[0031] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0032] Example 1, please refer to Figures 1 to 5 One embodiment of this utility model is an integrated explosion-proof grinding wheel combination box, which includes a combination box body 100, a mounting frame 200, a mounting plate 300, and a positioning structure 500.

[0033] The combined housing 100 is used for the installation of electrical components of the explosion-proof grinding wheel machine. The combined housing 100 is located at the bottom base of the explosion-proof motor of the explosion-proof grinding wheel machine. The mounting bracket 200 is located inside the combined housing 100. The mounting bracket 200 is U-shaped. The mounting plate 300 is fixed inside the mounting bracket 200. The mounting plate 300 is provided with a snap-fit ​​rail for snapping on electrical components and has holes for wiring.

[0034] The positioning structure 500 is used for positioning the mounting bracket 200 and the combined housing 100. The positioning structure 500 includes a positioning block 501, which passes through an opening in the mounting bracket 200. The positioning end of the positioning block 501 is inserted into a positioning hole 101 opened in the inner wall of the combined housing 100. A connecting block 502 is fixedly provided at the connecting end of the positioning block 501. A spring 503 is provided between the connecting block 502 and the mounting bracket 200. The two ends of the spring 503 are fixedly connected to the connecting block 502 and the mounting bracket 200, respectively. The elastic coefficient of the spring 503 is selected and used by the technical personnel in this field according to the actual situation. The spring 503 is always in a stretched state. The force generated by the stretched spring 503 acts on the connecting block 502, so that the positioning block 501 is kept under the force of being pushed towards the positioning hole 101.

[0035] The positioning end of the positioning block 501 is arc-shaped, and the arc-shaped surface of the positioning end of the positioning block 501 does not completely extend into the opening on the mounting bracket 200. A limiting block 504 is fixed on the positioning block 501, and the limiting block 504 contacts and engages with the inner wall of the mounting bracket 200. After the limiting block 504 contacts the inner wall of the mounting bracket 200, it limits the positioning block 501, so that the arc-shaped surface of the positioning end of the positioning block 501 can correspond to the inner wall of the combined box 100. When the mounting bracket 200 is pushed into the combined box 100, the arc-shaped surface of the positioning end of the positioning block 501 contacts the inner wall of the combined box 100, and the positioning block 501 is pushed open along the arc-shaped surface of the positioning end of the positioning block 501, which facilitates the pushing into the mounting bracket 200.

[0036] This utility model, by setting a positioning hole 101, a positioning block 501, a connecting block 502, a spring 503, and a limiting block 504, has the advantages of positioning the mounting bracket 200 after pushing it into the combined housing 100, and being able to push in or pull out the mounting bracket 200, making it convenient for workers to install or disassemble electrical components outside the combined housing 100. It solves the problem that when workers reach into the combined housing, the space is relatively small, making it inconvenient for workers to install or disassemble electrical components.

[0037] Example 2, please refer to Figures 2 to 4 This utility model provides an embodiment of an integrated explosion-proof grinding wheel assembly box. Two guide structures 400 are symmetrically arranged on the inner bottom wall of the assembly box 100. Each guide structure 400 includes a guide block A401, which is fixed to the inner bottom wall of the assembly box 100. A guide block B402 is connected to the front end of the guide block A401 via multiple telescopic rods 403. The fixed section of the telescopic rod 403 is inserted into and fixed within the guide block A401, while the movable end of the telescopic rod 403 is fixed to the guide block B402. The guide block B402 and guide block A401 slide in cooperation with two symmetrically opened grooves on the bottom side of the mounting frame 200. The guide block B402 is not completely detached from the inner bottom wall of the assembly box 100. When the mounting bracket 200 is pushed into the combined housing 100, the guide block B402 is pulled out relative to the guide block A401. The sliding groove at the bottom rear end of the mounting bracket 200, located outside the combined housing 100, first engages with the guide block B402, limiting the direction of the mounting bracket 200's push-in. When the operator pushes the mounting bracket 200 into the combined housing 100, the mounting bracket 200 and the guide block B402 move together due to the friction between them. If the mounting bracket 200 and the guide block B402 do not move together due to other factors, the mounting bracket 200 can be pushed in first, and then the guide block B402 can be pushed in without affecting the operation.

[0038] This utility model, by setting guide block A401, guide block B402 and telescopic rod 403, has the advantage of initially limiting the mounting bracket 200 externally when it is pushed into the combined box 100, so that the mounting bracket 200 is pushed into the combined box 100 accordingly.

[0039] Working principle: When the mounting bracket 200 with the installed electrical components is pushed into the combined housing 100, the guide block B402 is pulled out relative to the guide block A401. The sliding groove at the rear end of the bottom of the mounting bracket 200, located outside the combined housing 100, first engages with the guide block B402. The operator pushes the mounting bracket 200 into the combined housing 100, and the arc-shaped surface of the positioning end of the positioning block 501 contacts the inner wall of the combined housing 100. The positioning block 501 is pushed open along the arc-shaped surface of the positioning end of the positioning block 501, and the connecting block 502 is pushed accordingly. The spring 503 is further stretched until the positioning end of the positioning block 501 enters the opening on the mounting bracket 200. After the mounting bracket 200 is pushed into the rear installation position inside the combined housing 100, the positioning end of the positioning block 501 corresponds to the positioning hole 101. Under the action of the spring 503, the positioning end of the positioning block 501 is inserted into the positioning hole 101, thus positioning the mounting bracket 200. To disassemble the electrical components, pull the connecting block 502 so that the positioning end of the positioning block 501 leaves the positioning hole 101, pull out the mounting bracket 200, and disassemble the electrical components outside the combined housing 100.

[0040] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.
