[0035] The technical solutions provided by the embodiments of the present application are described below in conjunction with the drawings.

[0036] Please refer to Figures 1-8 In the present embodiment, a double-curved gear reducer shell convenient to install includes a shell 1 and a cover plate 2 detachably mounted on the upper end of the shell 1. A plurality of connecting pieces 3 are arranged on the lower end surface of the cover plate 2. The plurality of connecting pieces 3 are respectively distributed at the edges of each side of the cover plate 2 and arranged along the length direction of each side of the cover plate 2. The upper end surface of the shell 1 is provided with a connecting groove 11 matched with the connecting pieces 3. The connecting piece 3 includes a protruding portion 31 and a protruding portion 32 arranged on the side surface of the protruding portion 31. The protruding portions 32 of the plurality of connecting pieces 3 are arranged in the same direction. The connecting groove 11 includes a protruding portion 111 and a pressing portion 112. The protruding portion 32 is arranged in the pressing portion 112 through the protruding portion 111. A single connecting hole 21 is arranged at the edge of each side of the cover plate 2. The upper end surface of the shell 1 is provided with a fixing hole 12 matched with the connecting hole 21. The connecting hole 21 and the fixing hole 12 are connected by a bolt.

[0037] The protruding portion 32 is arranged in the pressing portion 112 through the protruding portion 111, realizing the connection of the shell 1 and the cover plate 2. A small amount of bolts are sequentially inserted through the connecting hole 21 and the fixing hole 12, realizing the close connection of the shell 1 and the cover plate 2. The arrangement of the connecting piece 3 realizes the connection of the shell 1 and the cover plate 2 through simple buckling. The four sides are further double-fixed by the bolts, realizing the close connection and the quick and convenient installation. The arrangement of the connecting piece 3 realizes higher connection stability.

[0038] In some embodiments, as Figures 1-5 shown, an annular retainer 13 is arranged in the fixing hole 12. The bolt is inserted into the inner cavity of the annular retainer 13. The outer side of the annular retainer 13 is sleeved with a return spring 4. The two ends of the return spring 4 are respectively abutted with the bottom of the fixing hole 12 and the lower end surface of the cover plate 2. It should be noted that the arrangement of the return spring 4 loosens the bolt and makes the protruding portion 32 separate from the pressing portion 112. The return spring 4 restores the deformation, thereby pushing out the cover plate 2 and making the cover plate 2 separate more easily.

[0039] In some embodiments, as shown in Figures 1-5 The upper end of the reset spring 4 is connected with a push plate 5, and the push plate 5 is provided with a through hole 51 matched with the connecting hole 21. The bolt is inserted into the fixed hole 12 through the connecting hole 21 and the through hole 51 in sequence. It should be noted that the setting of the push plate 5 increases the stress area of the shell 1, so that the push cover plate 2 is more stable.

[0040] In some embodiments, as shown in Figures 7-8 The convex portion 32 is a inclined block gradually inclined downward from inside to outside. It should be noted that when the reset spring 4 recovers the elastic deformation, the inclined surface of the convex portion 32 abuts against the inclined surface of the abutting portion 112, so that the cover plate 2 gradually separates from the shell 1, and the process is more stable.

[0041] In some embodiments, as shown in Figures 7-8 The inclined surface of the convex portion 32 is provided with an anti-skid pad 33. It should be noted that the setting of the anti-skid pad 33 prevents the inclined surface of the convex portion 32 from being abraded during the contact with the inclined surface of the abutting portion 112, and enhances the service life.

[0042] In some embodiments, as shown in Figure 6 The connecting pieces 3 on the front and rear sides of the cover plate 2 are symmetrically arranged and are in the form of long strips. It should be noted that the connection of the cover plate 2 and the shell 1 is more stable, and the cover plate 2 will not sway forward and backward.

[0043] In some embodiments, as shown in Figure 6 The connecting pieces 3 on the left and right sides of the cover plate 2 are symmetrically arranged. It should be noted that the connection of the cover plate 2 and the shell 1 is more stable, and the cover plate 2 will not sway left and right and forward and backward.

[0044] In some embodiments, the number of the connecting pieces 3 on the same side of the cover plate 2 is two, and the connecting pieces 3 on the same side of the cover plate 2 are located on the upper and lower symmetrical sides of the connecting hole 21. It should be noted that the connection of the left and right sides of the cover plate 2 and the shell 1 is more stable.

[0045] In some embodiments, as shown in Figure 6 The lower end surface of the cover plate 2 is provided with a buffer pad 22. It should be noted that the hard collision between the shell 1 and the cover plate 2 is prevented, the parts are not abraded, and the service life is longer.

[0046] Working principle: when the cover plate 2 is installed on the shell 1, the connecting pieces 3 on the cover plate 2 are aligned with the connecting grooves 11 of the shell 1, the convex portion 32 of the connecting piece 3 is placed in the abutting portion 112 through the extension portion 111 of the connecting groove 11, and the connecting hole 21 on the cover plate 2 is aligned with the fixed hole 12 on the shell 1. The bolt is inserted into the fixed hole 12 through the connecting hole 21 and the fixed hole 12 in sequence, and the installation of the cover plate 2 is completed.

[0047] When the cover plate 2 is detached from the shell 1, first, the bolt is detached, and the cover plate 2 is moved so that the protruding part 32 is moved out of the abutting part 112, in the moving process, the reset spring 4 restores the deformation, the reset spring 4 pushes the cover plate 2 upward to be detached through the pushing plate 5, the inclined surface of the protruding part 32 abuts against the inclined surface of the abutting part 112, preventing the cover plate 2 from being suddenly detached, so that the cover plate 2 is more stable in the detaching process, when the protruding part 32 is completely moved out of the abutting part 112, the cover plate 2 is detached.

[0048] The same or similar parts among the various embodiments in the specification can be referred to each other, and each embodiment focuses on the difference from other embodiments.

[0049] The above merely illustrates the specific embodiments of the present application, but the protection scope of the present application is not limited to this. Any person skilled in the art can easily think of the changes or replacements within the technical scope disclosed by the present application, which should be covered in the protection scope of the present application. Therefore, the protection scope of the present application should be subject to the protection scope of the claims.
