Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of container production, and more specifically, it relates to a pressing structure door. Background Art
[0002] In actual production, originally, 4 outer steel door panel parts needed to be cut by laser. The remaining material was irregular as a whole and there was not much that could be directly utilized. The 4 outer steel door panel parts needed to go through two cold bending operations and then be assembled and welded, but the cutting route and the welding route were repetitive, which led to the exposure of the weld beads and repetitive processing, seriously affecting the overall aesthetics and construction efficiency, increasing the burden on employees, with a low waste recovery rate. The increase in weld beads would also cause negative problems such as easy deformation of the flat plate. Content of the Utility Model
[0003] Aiming at the deficiencies of the existing technology, the purpose of the utility model is to provide a pressing structure door to solve one or more of the above problems.
[0004] To achieve the above purpose, the utility model provides the following technical solutions:
[0005] The pressing structure door includes a main box door with grooves and a box door leaf. The box door leaf is hinged in the groove body of the main box door. The main box door is welded by an outer steel door panel and a door inner lining plate. The outer steel door panel and the door inner lining plate are provided with a folded edge facing each other at the groove body. The outer steel door panel and the door inner lining plate are connected by inserting a Z-shaped PVC board. A rubber strip is filled between the main box door and the box door leaf.
[0006] Further, the Z-shaped PVC board is provided with insertion openings at both ends, and chamfers are provided at the ends of the insertion openings on the Z-shaped PVC board.
[0007] Further, a transverse cross-recessed head screw is inserted through one end of the Z-shaped PVC board inserted into the outer steel door panel, and the cross-recessed head screw passes through the Z-shaped PVC board and the outer steel door panel at the same time.
[0008] Further, the box door leaf has a structure that is wider outside and narrower inside. Notches are opened at both ends of the box door leaf, and the plate parts at the notches are all of single-folded edge structure.
[0009] Further, a three-joint PVC board is inserted into the notch of the box door leaf. The three-joint PVC board has a Z-shaped cross-section. Openings are provided at both ends of the three-joint PVC board. One end of the three-joint PVC board has a turned-up edge. Fixing screws are inserted and fixed between the three-joint PVC board and the two notches of the box door leaf.
[0010] Further, the middle section of the three-piece PVC board is butt-jointed with the rubber strip through fixing screws. The rubber strip abuts against the Z-shaped PVC board. One end of the rubber strip abutting against the Z-shaped PVC board is spherical, and one end of the rubber strip butt-jointing with the three-piece PVC board is flat. A flared opening is provided on the side surface of the flat end of the rubber strip, and the flared opening points to the door leaf of the box door.
[0011] In summary, the present utility model has the following beneficial effects: By improving the PVC board structure and optimizing the plate bending process, the construction efficiency is improved, the number of bending times and the number of weld beads are reduced, the deformation of the flat plate after welding is avoided, there is no need for exposed weld beads, and it is more beautiful. The shape of the remaining material after laser cutting and hollowing is regular, which is convenient for recycling and effectively reduces costs. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION OF THE EMBODIMENTS
[0017] Embodiment:
[0018] The following will further describe the present utility model in detail in conjunction with the attached Figures 1-4 drawings.
[0019] For existing structural doors, as Figure 3 and Figure 4 shown, four outer steel door panels 3 are cut by laser, bent twice through cold working bending, and assembled and welded with the help of F-shaped PVC board parts. However, the assembly edges need to go through cutting and welding successively, with repeated routes. The two bending processes also increase the construction burden. The cut remaining materials are not regular as a whole, which is not convenient for subsequent consumption. There are relatively many and long welding beads in the whole process, which is easy to cause deformation of the flat plate, and the welding beads at the R corner are extremely unsightly.
[0020] For the pressing-type structural door, as Figure 1 andFigure 2 As shown, it includes a main door 1 and a door leaf 2. A special slot is provided on the main door 1, which is used to hinge the door leaf 2, one end of which is a hinged end and the other end is a locking end. The hinged end is connected to the door leaf 2 through hinges and other components, and the locking end is controllably connected to the door leaf 2 through a lock head and a lock body.
[0021] The main door 1 is welded by the outer steel door panel 3 and the door inner lining panel 4, eliminating the two processes of cutting and welding, and directly using laser to make an integrated part. The remaining material is regular and square, and can be recycled. The formed main door 1 is bent once at the trough position through a cold bending process, and the ends are facing each other, but edge sealing and grinding are required. The gap is sealed with the help of the newly improved Z-shaped PVC board 5.
[0022] The Z-shaped PVC board 5 plugged with the outer steel door panel 3 and the door lining panel 4 has a Z-shaped cross section as the name implies, and is provided with plug-in openings 7 at both ends, and the ends of the plug-in openings 7 are chamfered for easy plug-in. A transverse cross countersunk screw 8 is provided at one end of the Z-shaped PVC board 5 plugged into the outer steel door panel 3 to reinforce the plug-in structure of the Z-shaped PVC board 5 and the outer steel door panel 3.
[0023] The door leaf 2 is a structure that is wide outside and narrow inside. The notches at both ends have a structure similar to the bent edge structure of the main door 1 and are fixed by plugging in a special three-joint PVC plate 9. The three-joint PVC plate 9 also has a Z-shaped cross-section structure. The difference from the Z-shaped PVC plate 5 is that the middle section of the three-joint PVC plate 9 needs to fix other components.
[0024] A rubber strip 6 is provided in the gap between the main door 1 and the door leaf 2. The rubber strip 6 contacts the Z-shaped PVC board 5 and the three-joint PVC board 9. The end of the rubber strip 6 that contacts the Z-shaped PVC board 5 is a spherical surface, and the end that connects to the three-joint PVC board 9 is a flat surface, which is convenient for plugging and fixing screws. Both ends of the three-joint PVC board 9 are provided with plug-in openings, and fixing screws are inserted at the plug-in ends, and the end that connects to the lining door panel has a warped edge 10. A flared mouth 11 pointing to the door leaf 2 is provided on the side of the flat end of the rubber strip 6.
[0025] Compared with the existing structural door, the structure of the compression type structural door provided by the present application has no exposed welds after being blocked, and the overall appearance is kept beautiful. The reduction in the number of welds and the shortening of the weld length are conducive to reducing the structural brittle points, and the plate is not easy to deform after welding.
[0026] The processing process of the compression structure door of the present application is as follows: after laser cutting the whole plate, a hole is laser-cut in the middle to leave a slot body of the size of the door opening, and the edge of the slot body is bent by cold working with a knife, and only one bending is required. The Z-shaped PVC board 5 is glued into the bent edge and fixed with a cross countersunk screw 8.
[0027] It should be noted that this specific embodiment is only an interpretation of the present utility model, and it does not limit the present utility model. After reading this specification, those skilled in the art can make modifications to this embodiment that do not contribute creatively as needed, but as long as it is within the scope of the claims of the present utility model, it is protected by the patent law.
