Detailed Description

The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.

Referring to fig. 1-4, the present invention provides a technical solution: a gear shifting device by means of a carrier gear comprises a housing 10.

Wherein, be equipped with first pivot 20 and shifting yoke 30 on the casing 10, first pivot 20 is equipped with two, two first pivot 20 surface all is equipped with duplicate gear 201, duplicate gear 201 includes gear A21 and gear B22, two intermeshing between the gear A21, two intermeshing between the gear B22, shifting yoke 30 surface is equipped with shifting fork 31, shifting fork 31 cooperatees with duplicate gear 201 and uses, shell 10 one side is rotated through second pivot 41 and mounting bracket and is installed carrier gear 42, shifting fork 31 is close to carrier gear 42 one side fixedly connected with rack 32, rack 32 and carrier gear 42 mesh mutually, carrier gear 42 is close to shell 10 bottom one side welding and has handle 40, rotates carrier gear 42 through pulling handle 40.

Two mounting grooves 311 are formed in the shift fork 31, two self-locking springs 312 are fixedly mounted in the mounting grooves 311, a self-locking steel ball 313 is fixedly connected to one end, close to the shift fork shaft 30, of each self-locking spring 312, and two grooves 301 corresponding to the self-locking steel balls 313 are formed in one side, close to the mounting grooves 311, of the shift fork shaft 30.

An opening 101 is formed in the bottom of the housing 10 on one side close to the intermediate gear 42, and the handle 40 penetrates through the opening 101 and then penetrates to the outside of the housing 10, so that a user can conveniently pull the handle 40 to shift gears by rotating the intermediate gear 42.

Wherein, two the mounting groove 311 is coaxial setting, two the recess 301 is coaxial setting.

The self-locking steel ball 313 is arranged in a spherical shape, and the groove 301 is arranged in a V shape, so that the self-locking steel ball 313 can be locked in the groove 301 or separated from the groove 301 better.

The working principle is as follows: when the gear shifting device is used, the handle 40 is pulled by hand to enable the handle 40 to rotate towards the B direction, so that the intermediate gear 42 is driven to rotate anticlockwise, the intermediate gear 42 drives the rack 32 to move, so that the shift fork 31 moves downwards, when the shift fork 31 moves, the shift fork 31 drives one of the dual gears 201 to move downwards, so that the gear A21 in the dual gear 201 is meshed with the gear A21 in the other dual gear 201, so that the other dual gear 201 is driven to rotate to achieve the purpose of shifting for one time, the handle 40 is continuously pulled to enable the intermediate gear 42 to rotate, so that the gear B22 in one dual gear 201 is meshed with the gear B22 in the other dual gear 201, so that the purpose of shifting for the second time is achieved, the purpose of fast shifting can be achieved, the gear shifting is simple and convenient, in the gear shifting process, the self-locking steel ball 313 can overcome the pressure of the pressure self-locking spring 312 to extrude the groove 301, after gear shifting is completed, the self-locking steel ball 313 is just pressed into the groove 301 of the declutch shift shaft by the self-locking spring 312, so that the positioning effect is completed, and automatic gear shifting is avoided.
