Description

Technical Field

[0001] The invention relates to the technical field of apartment beds, in particular to an easily disassembled dormitory apartment bed and a production process thereof. Background Art

[0002] In modern universities, corporate dormitories and other accommodation environments, dormitory apartment beds are basic and key facilities. Their design rationality and ease of use have an important impact on the living experience of residents. However, the traditional dormitory apartment beds currently used in large quantities on the market have many disadvantages in structural design, especially the fixed structure of the bed, which brings great troubles to daily use, maintenance and space adjustment.

[0003] The bed frame and the supporting frames on both sides of the traditional dormitory apartment bed are mostly connected by welding, bolting and other non-detachable or difficult-to-detach connection methods. This fixed structure may meet the basic use needs in the early stage of dormitory space planning. When the dormitory is redecorated and the layout is adjusted, the dormitory apartment bed needs to be moved out to make room, so some dormitory apartment beds may need to be disassembled. When disassembling the dormitory apartment bed, only the two supporting frames and the bed frame under the bed board need to be disassembled and removed. The fixedly connected bed frame and supporting frame often need to be disassembled using tools such as screwdrivers and wrenches, which not only increases the complexity of the operation, but also affects the renovation progress of the dormitory. Therefore, we propose a dormitory apartment bed that is easy to disassemble and a production process thereof. Summary of the invention

This fixed structure may meet the basic usage needs in the early stage of dormitory space planning. When the dormitory is redecorated and the layout is adjusted, the dormitory apartment bed needs to be moved out to free up space, so some dormitory apartment beds may need to be disassembled. When disassembling the dormitory apartment bed, only the two supporting frames and the bed frame under the bed board need to be disassembled and moved out. The fixedly connected bed frame and supporting frame often need to be disassembled using tools such as screwdrivers and wrenches, which not only increases the complexity of the operation, but also affects the renovation progress of the dormitory.

The electrostatic spraying voltage is controlled at 60-80kV, the distance between the spray gun and the component is maintained at 20-25cm, and the topcoat thickness is controlled at 60-80μm to ensure that the bed surface has good wear resistance and aesthetics. After the topcoat is sprayed, it is sent to the drying room for drying again. The drying temperature is set to 150-180°C and the drying time is 40-60 minutes to fully dry and cure the topcoat;

[0024] S9: After the bed support rods are dried, an anti-skid pad is embedded at the bottom of the bed support rods;

[0025] S10: This makes it easy to connect the bed frame to the support frames on both sides through detachable connectors, preliminarily connect the bed frame crossbeams and longitudinal beams through bolts and nuts, adjust the position and angle, and ensure that the connection is firm and reliable.

The first connecting arm 2 and the second connecting arm 4 are made of 3mm thick steel, and the supporting bed rod 1 is made of 4mm thick steel;

[0051] S2: Prepare sufficient anti-rust paint, primer and environmentally friendly topcoat. The anti-rust paint is epoxy zinc-rich paint, the primer is alkyd primer, and the topcoat is wear-resistant and scratch-resistant polyurethane paint to ensure the protection and beauty of the bed surface;

[0052] S3: Bolts and nuts are made of carbon steel of grade 8.8 or above, and the surface is galvanized to enhance rust resistance;

[0053] S4: Use a cutting machine to cut the bed frame 7, the supporting bed rod 1, the first connecting arm 2, the bed rail 3 and the second connecting arm 4, and the cutting size error is controlled within ±0.5mm;

[0054] S5: For the parts of the bed body that do not need to be frequently disassembled but need to be firmly connected, carbon dioxide gas shielded welding is used for welding. The iron plates used for fixing bolts on the first connecting arm 2 and the second connecting arm 4 and the steel pipes on the bed rails 3 need to be welded;

[0055] S6: Perform comprehensive rust removal on the processed parts. First, use shot blasting to remove rust. The shot blasting machine will project the projectiles at high speed onto the surface of the parts to remove rust, scale and other impurities on the surface. The shot blasting time is determined according to the rust degree and surface roughness requirements of the parts, generally 5-10 minutes;

[0056] S7: Evenly spray epoxy zinc-rich primer on the surface of the component after rust removal, using air spraying, with the spray gun 15-20 cm away from the component surface, the spraying pressure controlled at 0.3-0.5 MPa, and the primer thickness controlled at 40-60 μm, to ensure that the primer can fully cover the surface of the component to form a good anti-rust barrier. After the primer is sprayed, the component is sent to a drying room for drying, the drying temperature is set to 120-150° C., and the drying time is 30-40 minutes to fully cure the primer;

[0057] S8: After the primer is completely cured, the polyurethane topcoat is sprayed, and an electrostatic spraying process is used to improve the adhesion and uniformity of the topcoat. The electrostatic spraying voltage is controlled at 60-80kV, the distance between the spray gun and the component is maintained at 20-25cm, and the topcoat thickness is controlled at 60-80μm to ensure that the bed surface has good wear resistance and aesthetics.

The electrostatic spraying voltage is controlled at 60-80kV, the distance between the spray gun and the component is maintained at 20-25cm, and the topcoat thickness is controlled at 60-80μm to ensure that the bed surface has good wear resistance and aesthetics. After the topcoat is sprayed, it is sent to the drying room for drying again. The drying temperature is set to 150-180°C and the drying time is 40-60 minutes to fully dry and cure the topcoat; S9: After the support bed rod (1) is dried, the anti-skid pad (6) is embedded at the bottom of the support bed rod (1); S10: This makes it easy to connect the bed frame to the support frames on both sides through detachable connectors, preliminarily connect the bed frame crossbeams and longitudinal beams through bolts and nuts, adjust the position and angle, and ensure that the connection is firm and reliable.
