Description

Technical Field

[0001] The utility model relates to the technical field of painting rooms of painting lines, in particular to a quick-disassembly cover structure applied to sheet metal bending columns of painting rooms of painting lines. Background Art

[0002] The processes in an automobile painting workshop include: pretreatment, electrophoresis, painting, drying, gluing, grinding, inspection, etc. The painting room is a room for painting operations. Usually, the body of the painting room is made by bending sheet metal flat plates, which is beautiful, generous in shape and high in cost performance. Glass windows are arranged at appropriate positions in the height direction of the room body to facilitate observing the internal spraying operation conditions. Lighting fixtures are installed in the upper area near the glass windows to provide effective illuminance for the spraying operation. The power supply wires for the lighting fixtures are usually routed inside the sheet metal bending column for aesthetic reasons. Power supply wires are led out through reserved holes on the side of the column at the position close to the power supply interface of the light box. After the construction is completed, a cover plate is covered on the bending column.

[0003] In the prior art, usually two methods are adopted to connect the cover plate with the column. Method 1: Use self-tapping screws to lock the cover plate and the column together. Method 2: Install countersunk rivet nuts on the column, and corresponding round holes on the cover plate, and then use large socket head cap screws to lock the cover plate and the bending column. The above two connection methods between the cover plate and the column mainly have the following disadvantages: When the lamp circuit fails and the internal circuit of the column needs to be repaired, in Method 1, the self-tapping screws of the cover plate need to be removed to open the cover plate. This method has an irreversible repair problem for reinstalling the cover plate. The locking positions of the original self-tapping screws will wear the drilling positions of the column and the cover plate during disassembly, which may lead to locking failure and only re-drilling is possible, affecting the aesthetics. In Method 2, each large socket head cap screw on the cover plate needs to be removed, which is time-consuming and laborious. Summary of the Utility Model

[0004] How to improve the convenience of disassembling and assembling the cover plate during circuit maintenance is a difficult point to be solved. At the same time, improving the effectiveness and reliability of the connection between the cover plate and the column before and after maintenance needs to be considered even more. Therefore, in view of these problems, the utility model designs a quick-disassembly cover structure applied to sheet metal bending columns of painting rooms of painting lines, which has reliable connection, convenient maintenance and simple and compact structure.

[0005] The utility model is realized by the following technical solutions: A quick-disassembly cover structure applied to sheet metal bending columns of painting rooms of painting lines includes a first sheet metal bending column, a second sheet metal bending column, two column sealing plates, and a bending cover plate. The first sheet metal bending column and the second sheet metal bending column are symmetrical structures and are symmetrically and fixedly connected to each other. The two column sealing plates are respectively plugged and connected to the upper and lower parts of the first sheet metal bending column and the second sheet metal bending column.

[0006] In order to improve the disassembly and assembly convenience of the connection between the bent cover plate and the sheet metal bent column, so as to improve the maintenance convenience, it further includes several groups of cover plate locking devices. The first sheet metal bent column and the second sheet metal bent column are respectively bent inward to form a first notch and a second notch. The first notch and the second notch jointly form a column notch. The first notch and the second notch are respectively provided with a first opening part and a second opening part. The first opening part and the second opening part jointly form a column opening part. The bent cover plate is arranged in the column opening part. The cover plate locking device is connected to the bent cover plate and can lock or disengage the bent cover plate from the column opening part.

[0007] In order to improve the connection reliability between the bent cover plate and the sheet metal bent column, the cover plate locking device includes a triangular rotary lock and a bent tongue. The triangular rotary lock is connected to the bent cover plate through its outer end and can rotate freely. The bent tongue is arranged on the inner side surface of the column opening part and is fixedly connected to the inner end of the triangular rotary lock and can rotate with the triangular rotary lock.

[0008] Further, the bent tongue has a symmetrically bent sheet-like structure, with a length greater than that of the column opening part and a width smaller than that of the column opening part. Both sides are bent inward to form opening part matching parts that can be attached to the inner side surface of the column opening part.

[0009] To further improve the connection reliability, several groups of the cover plate locking devices are evenly distributed along the vertical direction of the bent cover plate.

[0010] In order to improve the strength of the bent cover plate on the premise of cost saving, both sides of the bent cover plate are bent inward to form notch matching parts that can be matched with the column notch. In order to improve the overall aesthetics, the bent cover plate is integrally embedded in the column notch, and the outer surface of the bent cover plate is flush with the outer surfaces of the first sheet metal bent column and the second sheet metal bent column.

[0011] The beneficial effects of the present utility model are as follows: The quick-disassembly cover plate structure applied to the sheet metal bent column of the spray booth in the painting line, by designing a cover plate locking device that can realize the quick disassembly and assembly of the cover plate and the sheet metal bent column, greatly improves the disassembly and assembly convenience of the connection between the cover plate and the sheet metal bent column, thereby improving the maintenance convenience; by further optimizing the structure of the cover plate locking device, the connection reliability between the cover plate and the sheet metal bent column is improved; by optimizing the cover plate structure, its strength is greatly improved on the premise of cost saving; in addition, the quick-disassembly cover plate structure applied to the sheet metal bent column of the spray booth in the painting line has a simple and compact structure and beautiful appearance.

[0018] As Figures 1-5 shown, a quick-detachable cover plate structure applied to the sheet metal bending column of the spray booth in the painting line includes a first sheet metal bending column 1, a second sheet metal bending column 2, two column sealing plates 3, a bending cover plate 4, and a plurality of groups of cover plate locking devices 5 evenly distributed along the vertical direction of the bending cover plate 4. The first sheet metal bending column 1 and the second sheet metal bending column 2 are symmetrical structures and are symmetrically fixedly connected to each other. The two column sealing plates 3 are respectively plugged and connected to the upper and lower parts of the first sheet metal bending column 1 and the second sheet metal bending column 2.

[0019] The first sheet metal bent column 1 and the second sheet metal bent column 2 are respectively bent inward to form a first notch 11 and a second notch 21. The first notch 11 and the second notch 21 together form a column notch 6. The first notch 11 and the second notch 21 are respectively provided with a first opening 111 and a second opening 211. The first opening 111 and the second opening 211 together form a column opening 7. The bent cover plate 4 is arranged in the column opening 7. Both sides of the bent cover plate 4 are bent inward to form notch matching parts 41 that can cooperate with the column notch 6. The whole bent cover plate 4 is embedded in the column notch 6, and the outer surface of the bent cover plate 4 is flush with the outer surfaces of the first sheet metal bent column 1 and the second sheet metal bent column 2. The cover plate locking device 5 is connected to the bent cover plate 4 and can lock or unlock the bent cover plate 4 from the column opening 7.

[0020] The cover plate locking device 5 includes a triangular rotary lock 51 and a bent tongue 52. The bent tongue 52 is in a symmetrically bent sheet-like structure, with a length greater than that of the column opening 7 and a width less than that of the column opening 7. Both sides are bent inward to form opening matching parts 521 that can be attached to the inner side surface of the column opening 7. The triangular rotary lock 51 is connected to the bent cover plate 4 through its outer end and can rotate freely. The bent tongue 52 is arranged on the inner side surface of the column opening 7 and is fixedly connected to the inner end of the triangular rotary lock 51 and can rotate with the triangular rotary lock 51.

[0021] During use, the bent cover plate 4 is embedded in the column notch 6 so that it can completely seal the column opening 7. The triangular rotary lock 51 is rotated so that the bent tongue 52 is in a horizontal state. As Figures 2-3 shown, the opening matching parts 521 on both sides of the bent tongue 52 are attached to the inner side surface of the column opening 7, and thus the locking of the bent cover plate 4 with the first sheet metal bent column 1 and the second sheet metal bent column 2 can be completed. When it is necessary to repair the internal lines of the column, only the triangular rotary lock 51 needs to be rotated in the reverse direction by a certain angle. As Figures 4-5 shown, the unlocking of the bent cover plate 4 can be quickly achieved, and it can be disassembled and assembled repeatedly without damaging the bent cover plate 4, which is different from the connection structure between the column and the cover plate in the prior art shown in Figure 6 shown, and the maintenance is convenient.
