Description

Technical Field

[0001] The utility model relates to the field of splicing of honeycomb aluminum plates, and specifically relates to a splicing device for honeycomb aluminum plates used in bullet trains. Background Art

[0002] Honeycomb aluminum plates are a series of metal composite plate products developed by combining the composite honeycomb plate technology of the aviation industry. In decoration, we can basically use honeycomb plates to bear the weight of simple equipment, for better aesthetics, and they also have a certain sound insulation effect. However, when installed on the ceiling, the installation requirements not only require aesthetics, but also require the stability of the honeycomb plates.

[0003] Most of the existing installations of honeycomb aluminum plates use bolts for fixation. However, although bolt installation provides fixation stability, it is not convenient for quick installation and disassembly, thus failing to meet better comprehensive installation requirements. Therefore, new technical solutions need to be designed to solve this problem. Content of the Utility Model

[0004] The purpose of the utility model is to overcome the deficiencies of the prior art, meet the actual needs, and provide a splicing device for honeycomb aluminum plates used in bullet trains, so as to solve the technical problem that most of the current installations of honeycomb aluminum plates use bolts for fixation. Although bolt installation provides fixation stability, it is not convenient for quick installation and disassembly, thus failing to meet better comprehensive installation requirements.

[0005] In order to achieve the purpose of the utility model, the technical solution adopted by the utility model is as follows: design a splicing device for honeycomb aluminum plates used in bullet trains, including an aluminum plate body, a main cross plate, and a secondary cross plate. Both sides of the surface of the secondary cross plate are fixedly connected with mounting plates. Bolts penetrate through both mounting plates, and the bolts are threadedly connected to the surface of the main cross plate;

[0006] One end of the aluminum plate body is fixedly connected with a rectangular frame. Rectangular grooves are opened on the outer sides of both ends of the rectangular frame. Connecting shafts are rotatably connected between the two sides of the inner cavities of the two rectangular grooves. Clamping plates are fixedly connected to the middle parts of the two connecting shafts. Torsion springs are installed on the outer sides of the connecting shafts on both sides of the clamping plates.

[0007] Preferably, a plurality of threaded holes are equidistantly opened on the main cross plate, and the plurality of threaded holes are equidistantly distributed on the main cross plate, and the plurality of threaded holes are all adapted to the bolts.

[0008] Preferably, a clamping groove is opened on one side of the surface of the secondary cross plate, and the internal dimensions of the clamping groove are adapted to the external dimensions of the clamping plate.

[0009] Preferably, connecting pull rods are fixedly connected to both sides of one end of the main cross plate close to the threaded holes.

[0010] Preferably, the torsion springs on both sides of the clamping plate have the same size and specification.

[0011] Compared with the prior art, the beneficial effects of the present utility model are as follows:

[0012] 1. Through the combination of structures such as the main cross plate, the secondary cross plate, the clamping plate, the rectangular groove, the connecting shaft, the torsion spring, the aluminum plate body, and the rectangular frame, the present utility model turns the clamping plate vertically to wind up the torsion spring, and then inserts the clamping plate and the rectangular frame together between two main cross plates and two secondary cross plates. When the clamping plate passes over the secondary cross plate, the elastic force of the torsion spring drives the clamping plate to rotate and overlap on the secondary cross plate, thereby clamping the aluminum plate body on the two secondary cross plates, and then quickly splicing the aluminum plate body. When it is necessary to disassemble the aluminum plate body, by means of a suction cup (prior art) adsorbed on the middle of the aluminum plate body, and then pulling the aluminum plate body downward. When the pulling force on the aluminum plate body is greater than the winding force of the torsion spring, it drives the clamping plate to rotate and disengage from the secondary cross plate. Thus, only by sucking the aluminum plate body with the suction cup and pulling it downward can the disassembly of the aluminum plate body be completed. Compared with the prior art of splicing by bolts, the splicing efficiency of the aluminum plate body is greatly improved.

[0013] 2. Through the setting of the clamping groove, when splicing the aluminum plate body, the clamping plate is placed in the clamping groove, thereby limiting the clamping plate, and further improving the stability of the aluminum plate body after splicing. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0019] The present utility model will be further described below in conjunction with the drawings and embodiments:

[0020] Embodiment 1: A splicing device for honeycomb aluminum plates used in bullet trains, see Figures 1 to 4, comprising an aluminum plate body 1, a main transverse plate 21 and a secondary transverse plate 2, both sides of the surface of the secondary transverse plate 2 are fixedly connected with mounting plates 23, both mounting plates 23 are penetrated by bolts 24, and the bolts 24 are threadedly connected to the surface of the main transverse plate 21;

[0021] One end of the aluminum plate body 1 is fixedly connected to a rectangular frame 11, and rectangular grooves 3 are provided on the outer sides of both ends of the rectangular frame 11. A connecting shaft 31 is rotatably connected between the two inner cavities of the two rectangular grooves 3. A clamping plate 33 is fixedly connected to the middle of the two connecting shafts 31. Torsion springs 32 are installed on the outer sides of the connecting shafts 31 on both sides of the clamping plate 33. The torsion springs 32 on both sides of the clamping plate 33 have the same size and specification. When working, the secondary cross plate 2 and the main cross plate 21 are vertically connected to each other by tightening the bolts 24, and the distances between the two main cross plates 21 and the two secondary cross plates 2 are respectively adapted to the length and width of the rectangular frame 11. At the same time, the bottoms of the main cross plate 21 and the secondary cross plate 2 are placed on the same horizontal plane, and then the clamping plate 33 is moved to be placed vertically, so as to adjust the torsion springs 32. After tightening, the card plate 33 and the rectangular frame 11 are inserted between the two main cross plates 21 and the two secondary cross plates 2. When the card plate 33 passes over the secondary cross plates 2, the elastic force of the torsion spring 32 drives the card plate 33 to rotate and overlap on the secondary cross plates 2, thereby clamping the aluminum plate body 1 on the two secondary cross plates 2, and then quickly splicing the aluminum plate body 1. When it is necessary to disassemble the aluminum plate body 1, it is adsorbed on the middle part of the aluminum plate body 1 with the help of a suction cup (existing technology), and then the aluminum plate body 1 is pulled downward. When the pulling force on the aluminum plate body 1 is greater than the force of the torsion spring 32, the card plate 33 is driven to rotate and detach from the secondary cross plates 2, so that the aluminum plate body 1 can be disassembled by only sucking the aluminum plate body 1 with the suction cup and pulling it downward. Compared with the existing splicing through bolts 24, the efficiency of splicing of the aluminum plate body 1 is greatly improved.

[0022] For details, see Figure 2 A plurality of threaded holes 26 are equidistantly provided on the main cross plate 21, and the plurality of threaded holes 26 are equidistantly distributed on the main cross plate 21, and the plurality of threaded holes 26 are all adapted to the bolts 24. By setting the plurality of threaded holes 26, the distance between the two sub-cross plates 2 can be adjusted when the bolts 24 are connected to different threaded holes 26, so that aluminum plate bodies 1 of different sizes can be clamped, thereby improving the practicability of splicing the aluminum plate bodies 1.

[0023] For further information, see Figure 2 A card slot 25 is provided on one side of the surface of the secondary cross plate 2, and the internal size of the card slot 25 is adapted to the external size of the card plate 33. Through the setting of the card slot 25, when the aluminum plate body 1 is spliced, the card plate 33 is placed in the card slot 25, thereby limiting the card plate 33, thereby improving the stability of the aluminum plate body 1 after splicing.

[0024] It is worth noting that seeFigure 1 On both sides of one end of the main cross plate 21 close to the threaded hole 26, connecting pull rods 22 are fixedly connected, and the main cross plate 21 can be conveniently fixed to the top inside the room through the connecting pull rods 22.

[0025] In addition, the components designed in the present utility model are all common standard components or components known to those skilled in the art. Their structures and principles can all be learned by those skilled in the art through technical manuals or through conventional experimental methods. Those skilled in the art can fully implement them without further elaboration. The content protected by the present utility model does not involve improvements to the internal structure and method either.
