[0017] In order to make the purpose, technical scheme and advantages of the embodiments of the utility model clearer, the technical scheme of the embodiments of the utility model will be described clearly and completely below in combination with the drawings in the embodiments of the utility model. Obviously, the described embodiments are part of the embodiments of the utility model, not all the embodiments. The components of the embodiments of the utility model described and shown in the drawings can be arranged and designed in various different configurations.

[0018] Therefore, the following detailed description of the embodiments of the utility model provided in the drawings is not intended to limit the scope of the claimed utility model, but only represents selected embodiments of the utility model. Based on the embodiments in the utility model, all other embodiments obtained by those of ordinary skill in the art without creative labor are within the scope of protection of the utility model.

[0019] It should be noted that similar reference numerals and letters represent similar items in the following drawings. Therefore, once an item is defined in one drawing, it does not need to be further defined or explained in subsequent drawings. In addition, the terms "first," "second," etc. are used only to distinguish the descriptions and are not to be understood as indicating or implying relative importance.

[0020] In the description of the embodiments of the present invention, it should be noted that the terms "inside", "outside", "upper", etc. indicate orientations or positional relationships based on the orientations or positional relationships shown in the accompanying drawings, or are the orientations or positional relationships in which the product of the present invention is usually placed when in use. They are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation. Therefore, they cannot be understood as a limitation on the present invention.

[0021] like Figs. 1-3 As shown, a combination lock for a two-wheeled vehicle trunk includes a lock body 4, a lock cover 1 disposed at one end of the lock body 4, a lock hook 3 disposed at the other end of the lock body 4, a lock cylinder housing 2 disposed outside the lock body 4, and a return spring disposed between the lock body 4 and the lock cylinder housing 2. The above are all prior art disclosed in Chinese Patent CN206874094U. The lock surface of the lock cover 1 is configured as an electroplated surface, which improves the aesthetics of the lock cover 1.

[0022] The lock body 4 and the lock cover 1 are arranged in the trunk, so that the trunk can be used to protect the lock body 4 and the lock cover 1. On the one hand, the probability of damage to the lock body 4 and the lock cover 1 can be reduced, and on the other hand, the aesthetics of the entire combination lock on the trunk can be improved.

[0023] The inner side wall of the lock cylinder housing 2 is arranged away from the outer surface of the lock body 4. By setting the inner diameter of the lock cylinder housing 2 to be larger than the outer diameter of the lock body 4, the friction area between the two can be effectively reduced. A support ring 6 is fixedly mounted on the inner side wall of the lock cylinder housing 2, and the inner annular surface of the support ring 6 is in sliding contact with the lock body 4. A support bar 5 is provided on the inner side wall of the lock cylinder housing 2 on one side of the support ring 6. With the help of the support ring 6 and the support bar 5, the lock cylinder housing 2 and the lock body 4 can be brought into contact with each other while reducing the friction area, maintaining the stability of the rotation process between the two. A plurality of support bars 5 are provided, and the plurality of support bars 5 are distributed at equal intervals. Arranging a plurality of support bars 5 can further enhance the stable positioning effect of the lock body 4 during the rotation process.

[0024] In summary: after the combination lock is opened, when the lock hook 3 and the lock core sleeve housing 2 are driven by the lock body 4 to rotate relative to each other, the actual contact area between the two is reduced, thereby reducing the wear of the lock body 4 during the rotation process, thereby increasing the number of times the lock body 4 can rotate and improving its service life.

[0025] The above description enables one of ordinary skill in the art to make or use the application. Various modifications to these embodiments will be readily apparent to those skilled in the art, and the generic principles defined herein can be applied to other embodiments without departing from the spirit or scope of the application. Thus, the present application is not intended to be limited to the embodiments shown herein but is to be accorded the widest scope consistent with the principles and novel features disclosed herein.
