The general structure of desks and chairs is divided into: desktop/chair surface/chair back, table bucket, steel frame and other main components;
Seat/back/table top: usually use multi-layer hot pressing adhesive bonded refractory board or molded board, but also can use PP (polypropylene) injection molding panel, or PE(polyethylene) hollow blow molding panel;
Stand/table bucket: the surface of low-carbon A3 cold-rolled steel tube is generally welded, polished, oil removed, rust removed, pickling, phosphating and high temperature electrostatic spraying anti-rust protection treatment, or the table bucket can be molded by injection.
1. Healthy and comfortable, environmentally friendly and durable.
Unique design, ergonomic, second design.Make the back get very good relax.
2. Bright color and no peculiar smell.
Humanized design, read and write without lowering one's head, effectively help children correct sitting position, prevent hunchback myopia.
3. Focus on posture adjustment and improvement.
Leaning desktop science, arc engineering back rest, relieve pressure, relax learning.
4. Powder spraying and welding.
Spray powder with high quality texture plastic powder, prevent falling off, more resistant to dirt, wear resistance, scratch resistance, easy to clean characteristics.Using intelligent welding technology, smooth, smooth, stronger and more beautiful.
5.Lifting sleeve and high quality screw.
Select the high quality fixed lifting cover, so that the desks and chairs are more durable, there will be no lifting cover up or fall off the situation.High quality screws are adopted to reduce wear and prolong service life.Prevent screw damage in the process of adjusting the lift.
1. Material description.
The tabletop uses the high density medium fiber board, the injection molding machine once forms the sealing edge. The book net is made of thick steel wire after stamping and welded by touch welding machine. The table frame is made of high quality thickened steel tubes bent by automatic pipe bending machine, without wrinkles, with smooth surface and non-slip rubber pad in contact with the ground.
2. Strong and durable.
Table legs and table legs adopt elliptical steel tubes for better tensile strength and wear resistance.After advanced electrostatic spraying process, the coating and metal surface adhesion is stronger, not easy to corrosion, not easy to fall off.
3. Simple appearance design.
Abandon the complex structure, simple design, simple and firm structure.Let students not confined in the space, with a small amount of material, set aside more storage space.
4. Drawer design.
Hollow-out drawer design, open drawer, more convenient to find things, a number of hooks design, let the bag can be put.
5. Foot cover design.
Adopt new polyethylene environmental protection material, non-toxic and tasteless, with rounded corner design, can effectively prevent children collision injury, avoid noise when moving.
Inspection System: Checking quality before packing.
Professional packaging, attention to detail.
Disassembly structure: flat packing, reduce the volume of product packaging, convenient logistics transportation and handling, effectively reduce the rate of damage.
Internal packaging: double-layer foam board is used to cushion and resist pressure, and the four corners are covered with kraft paper to prevent knock and collision. Each part is wrapped with pearl cotton to prevent abrasion and skid, thus greatly reducing the damage to the product during transportation.
External packaging: The external carton is made of double-sided five-layer corrugated paper, namely three-core double-sided seven-layer cardboard, with two layers of cardboard and three layers of corrugated base paper.
Special packing: for some commodities or special customers, we will use the form of carton + wooden frame/wooden case for packing, to protect the products intact to the greatest extent.
Provide all kinds of training special desks and chairs, multi-function meeting product model simple and novel, quality durable, widely used in various places in primary and secondary school classroom, large and medium-sized institutions, professional on-the-job training structure, cram schools, enterprises and institutions training classrooms, a large lecture hall, meeting training classrooms, multimedia classrooms, multi-functional conference hall, etc.
Main Manufacturing process
Production process: from procurement to sheet metal mechanical treatment to anti-rust decontamination painting, every step is meticulously produced.
Sheet metal mechanical processing: cutting processing, stamping processing, bending, welding processing;
Spray pretreatment: hot water washing, preparation for degreasing, main degreasing, three lines of water washing, skin film generation, three lines of water washing;
Electrostatic powder spraying: the use of environmentally friendly phosphor-free organic film conversion layer, coating uniform appearance, degree of crystalline density, adhesion, mechanical strength, wear resistance and rust resistance performance is better.
A) Strictly calibrate and position materials to ensure the accuracy of material size.
B) Before welding: check again whether the material is damaged, dented or unequal in size;
C) In welding: false welding, missing welding and large welding scar are not allowed;
D) Before delivery, factory inspection or photo inspection can be carried out as required by the customer;
Improper desks and chairs have a great effect on students' health
(1) chair is too high, too high, can't tread flat on the ground, the gravity of the calf makes back thigh blood vessels and nerves oppressed, poor blood flow, lower limb numbness, or in order to make the feet step on the ground, to the whole body move forward, make hip sit in the chair front, double upper body weight, body fell on the table.
(2) the chair is too low: when the chair is too low, ham cannot focus on chair face entirely, big crus presents acute Angle, cox bears heavy load greatly, easy fatigue.
(3) The height difference of desks and chairs is too large: when the table is too high or the chair is too low, the height difference of desks and chairs can increase. The height difference of desks and chairs is too close to the table when students read and write. When they write, their shoulders are hunched or they can only put one arm on the table, which can easily form scoliosis and myopia.
(4) Too small height difference between tables and chairs: if the height difference is too small, the head, neck and torso can be bent forward, and the upper limbs can support the weight of the upper body on the table, forming the posterior protrusion of the spine.The above four conditions are habitual postures at the beginning, which are relatively easy to correct.However, this kind of habitual posture without correction for a long time is likely to cause fixed bone bending, which needs to be systematically corrected for a long time.
