Description

Technical Field

[0001] The utility model belongs to the technical field of disassembly devices, and in particular relates to a water tank cover assembly and disassembly tool used in a hydrogen fuel cell cooling system. Background Art

[0002] In hydrogen fuel cell vehicles, the expansion water tank is usually called an "expansion water separator" or "expansion tank". It is an essential safety functional component in the hydrogen fuel cell cooling system.

[0003] Ensure that the supply of hydrogen and oxygen in the system is stable and safe. At present, the lid of the expansion tank has the problem of being difficult to unscrew. Although the water tank cover is provided with anti-slip convex patterns, after long-term use, due to the expansion of the cover mouth, a tight seal is formed between the lid and the cover mouth, which increases the difficulty of disassembly. Therefore, it is necessary to use external tools to assist in disassembling the water tank cover. Chinese patent document: CN201922132844.2 discloses a fuel tank cap disassembly device. The clamping ring in the application is provided with multiple slots corresponding to multiple ridges, each ridge is accommodated and limited in each slot, and the bending assembly includes a connecting plate and a handle assembly connected to the connecting plate. The clamping ring is arranged on the side of the connecting plate facing away from the handle assembly. By twisting the handle assembly, the connecting plate can be driven, and then the clamping ring can be driven to rotate. The clamping ring further drives the box cover to rotate through the limiting clamping cooperation of multiple slots and multiple ridges, thereby realizing the disassembly of the box cover. Due to the integrated connection structure between the wrench assembly and the connecting plate, the disassembly structure of the disassembly device in the application is relatively simple, and the overall structure is relatively complex, and the size structure is relatively large, which is not convenient for operation. Utility Model Content

[0004] In view of the above problems, the utility model discloses a water tank cover assembly and disassembly tool, which can be fully adapted to the surface of the water tank cover and can be used with various types of wrenches, and is simple and convenient to operate.

[0005] The specific technical solutions are as follows:

[0006] A water tank cover assembly and disassembly tool is used to disassemble the water tank cover. The outer peripheral wall of the cover is convexly provided with a plurality of convex ridges arranged at intervals. The disassembly tool comprises a set cover for being mounted on the water tank cover. The set cover is circular, and a plurality of card slots adapted to the convex ridges are opened on the inner side wall of the set cover, and the lower ends of the card slots extend to the bottom end of the set cover and correspond one-to-one with the convex ridges; a wrench seat is fixedly provided at the top center of the set cover, and the wrench seat is a regular polygonal prism structure, and a wrench groove for inserting a wrench is opened at the top center of the wrench seat.

[0007] Furthermore, the wrench slot has a square structure or a regular hexagonal structure.

[0008] Further, the wrench groove includes a square hole groove provided at the upper end for a square wrench to be inserted therein, and a hexagonal groove provided at the lower end of the square hole groove for an internal hexagonal wrench to be inserted therein.

[0009] Further, the inner walls at the front and rear ends of the hexagonal groove are flush with the edges of the inner walls at the front and rear ends of the square hole groove. Both the left and right ends of the hexagonal groove are provided with V-shaped grooves, and the two V-shaped grooves extend upward to the inner wall of the square hole groove.

[0010] Further, a polygonal structure projection block is convexly provided at the center of the top of the sleeve cover. An insertion groove adapted to the projection block is provided at the bottom of the wrench seat, and the projection block and the insertion groove are fixedly connected by a fastening member.

[0011] Further, both sides at the bottom end of the card slot are provided with flared openings.

[0012] The beneficial effects of the present utility model are embodied in:

[0013] The present utility model directly sleeved the sleeve cover on the water tank cover, so that the convex rib and the card slot are mutually engaged. Subsequently, various wrench tools can be inserted into the wrench groove or sleeved on the wrench seat, so that the water tank cover can be quickly disassembled, the operation is simple and convenient, and it can be used for various types of wrenches.

[0022] Embodiment 1

[0023] As Figure 1-2 shown, this embodiment provides a water tank cover assembly and disassembly tool for disassembling the water tank cover 1. A plurality of convex ribs 11 are provided on the outer peripheral wall of the cover 1 at intervals. The disassembly tool includes a sleeve cover 2 for sleeving on the water tank cover 1. The sleeve cover 2 is circular. A plurality of clamping grooves 21 adapted to the convex ribs 11 are provided on the inner side wall of the sleeve cover 2. The lower ends of the clamping grooves 21 extend to the bottom end of the sleeve cover 2 and correspond to the convex ribs 11 one by one. A wrench seat 3 is fixedly provided at the center of the top of the sleeve cover 2. The wrench seat 3 is connected to the sleeve cover 2 by welding. The wrench seat 3 has a regular hexagonal prism structure and can be sleeved with an external hexagonal wrench for screwing and disassembling operations. A wrench groove 31 for the wrench to be inserted is provided at the center of the top of the wrench seat 3. The wrench groove 31 has a square structure or a regular hexagonal structure, so that a square wrench or an internal hexagonal wrench can be inserted into the wrench groove 31 for screwing and disassembling operations.

[0024] Embodiment 2

[0025] As Figure 3 shown, in this embodiment, in order to avoid the problem that the welding joint breaks due to excessive acting force during screwing of the wrench seat 3, the difference between this embodiment and Embodiment 1 is that a polygonal structure raised block is provided convexly at the center of the top of the sleeve cover 2, and an insertion groove 30 adapted to the raised block is provided at the bottom of the wrench seat 3. The raised block and the insertion groove 30 are fixedly connected by longitudinally penetrating a screw fastener 4. Through the cooperation of the raised block and the insertion groove 30, horizontal direction limitation is achieved, thereby avoiding the problem that the wrench seat 3 is separated from the sleeve cover 2 during screwing.

[0026] In this embodiment, both sides of the bottom end of the card slot 21 are flared, so as to facilitate the quick insertion between the card slot 21 and the convex rib 11 and avoid jamming.

[0027] Embodiment 3

[0028] As Figure 4-5 shown, in this embodiment, in order to further improve the adaptation range of the wrench seat 3, the difference between this embodiment and Embodiment 1 is that the wrench slot 31 includes a square hole slot 32 provided at the upper end for a square wrench to be inserted and a hexagonal slot 33 provided at the lower end of the square hole slot 32 for an internal hexagonal wrench to be inserted. The inner walls at the front and rear ends of the hexagonal slot 33 are flush with the edges of the inner walls at the front and rear ends of the square hole slot 32. Both the left and right ends of the hexagonal slot 33 are provided with V-shaped slots, and the two V-shaped slots extend upward to the inner wall of the square hole slot 32. By opening the hexagonal slot 33 in the deep hole at the bottom of the square hole slot 32, the wrench slot 31 can be applicable to both the square wrench and the internal hexagonal wrench, and the application range is wider.

[0029] The above is only a preferred specific embodiment of the present invention, but the protection scope of the present invention is not limited thereto. Any changes or substitutions that can be easily thought of by those skilled in the art within the technical scope disclosed by the present invention should be covered by the protection scope of the present invention. Therefore, the protection scope of the present invention should be subject to the protection scope of the claims.
