[0023] In order to be able to more clearly understand the technical means of the present utility model and implement it according to the content of the specification, the following combines the drawings and embodiments to further describe in detail the specific embodiments of the present utility model. The following embodiments are used to illustrate the present utility model but do not limit the scope of the present utility model.

[0024] Please refer to Figures 1-5 As shown, the handle throttle cruise control lock body structure disclosed in this embodiment includes an installed rear shell 1 and a cover plate 17 detachably provided on the outer side surface of the installed rear shell 1. The installed rear shell 1 and the cover plate 17 are mutually clamped to form an installation housing. A through groove 5 is penetrated and opened on the installation housing. The installation housing formed by installing the cover plate 17 on the outer side surface of the installed rear shell 1 is used to be installed on a motorcycle. And the inner cavity of the throttle installed rear shell 1 is divided into a positioning cavity 2, a locking cavity 3 and a reset cavity 4. The positioning cavity 2 is located below the inner cavity of the installed rear shell 1. The shape of the locking cavity 3 is circular and is located above the positioning cavity 2 and is communicated with the locking cavity 3. The reset cavity 4 is located on the side of the locking cavity 3 and is located above the positioning cavity 2. The reset cavity 4 is communicated with the locking cavity 3.

[0025] A limiting ring 12 is detachably arranged in the inner cavity of the through groove 5. The limiting ring 12 has a certain elasticity. Since the limiting ring 12 is installed in the inner cavity of the through groove 5, the throttle grip contacts the inner wall surface of the limiting ring 12 through the through groove 5. When the throttle grip rotates, the limiting ring 12 will also rotate. A locking mechanism for locking the limiting ring 12 is arranged in the inner cavity of the locking cavity 3. A driving mechanism for driving the locking mechanism to move is arranged in the inner cavity of the locking cavity 3. A limiting mechanism for positioning the driving mechanism is arranged in the inner cavity of the positioning cavity 2.

[0026] The locking mechanism includes two positioning rods 6 and two locking pieces 7. The bottom ends of the two positioning rods 6 are fixedly connected to the inner cavity of the locking cavity 3 and are arranged in a mirror image with respect to the center of the locking cavity 3. The two locking pieces 7 are both detachably arranged in the inner cavity of the locking cavity 3. One ends of the two locking pieces 7 respectively take the two positioning rods 6 as the rotation centers. One end of the locking piece 7 is rotatably sleeved on the positioning rod 6. The two locking pieces 7 are in a semi-circular shape. When installed in the inner cavity of the locking cavity 3, they form a circular ring. When the two locking pieces 7 rotate with the corresponding positioning rods 6 as the centers, the other ends of the two locking pieces 7 approach each other and move towards the center of the locking cavity 3, that is, the center direction of the through groove 5, so as to squeeze the limiting ring 12. The limiting ring 12 locks and positions the throttle grip through friction and abutment. When it is necessary to cancel the fixation of the throttle grip, the other ends of the two locking pieces 7 are reset to release the lock. Two auxiliary rods 20 are fixedly connected to the two locking pieces 7. When the two locking pieces 7 are installed on the locking cavity 3, their positions are arranged in a mirror image with respect to the center of the locking cavity 3.

[0027] A driving ring 8 is detachably arranged on the outer side surface of the locking cavity 3. Two first sliding grooves 22 are arranged on the surface of the driving ring 8 along the vertical direction, and the two first sliding grooves 22 correspond to the positioning rods 6. The top ends of the two positioning rods 6 respectively penetrate through the corresponding two first sliding grooves 22. Therefore, when the two locking pieces 7 rotate, the top ends of the positioning rods 6 can slide in the inner cavity of the first sliding grooves 22, playing a role in positioning the rotation direction of the locking pieces 7 and ensuring the contact effect between the locking pieces 7 and the limiting ring 12. Two second sliding grooves 23 are arranged horizontally on the surface of the driving ring 8. The two second sliding grooves 23 correspond to the two auxiliary rods 20 one by one and respectively penetrate to the corresponding second sliding grooves 23. When the two locking pieces 7 rotate, the auxiliary rods 20 move along the direction of the second sliding grooves 23, making the rotation of the locking pieces 7 more stable. And in the locked state, the moving directions of the two auxiliary rods 20 are towards each other. In the case of canceling the lock, the moving directions of the two auxiliary rods 20 are away from each other.

[0028] The surface of the driving ring 8 is fixedly connected with a fixed handle 9. An upper through hole 18 for the fixed handle 9 to penetrate to the outside is formed on the surface of the installation rear shell 1. Through the fixed handle 9, the user can rotate the driving ring 8. Through the rotation of the driving ring 8 and the cooperation of the first sliding groove 22 and the second sliding groove 23, the two locking members 7 can be driven to rotate, so as to lock or unlock the limiting ring 12. The upper through hole 18 can meet the requirement for the fixed handle 9 to move in the vertical direction.

[0029] Furthermore, a convex block 21 penetrating into the inner cavity of the reset cavity 4 is also arranged on the surface of the driving ring 8. The inner cavities of the locking cavity 3 and the reset cavity 4 are connected. The convex block 21 can move upward or downward in the vertical direction under the rotation of the driving ring 8. A first elastic member 15 is arranged at the bottom of the inner cavity of the reset cavity 4. The bottom of the convex block 21 is in contact with the top end of the first elastic member 15. When the two locking members 7 lock and tighten the limiting ring 12 by rotating the driving ring 8, the convex block 21 moves downward in the vertical direction, and the first elastic member 15 is compressed to generate an elastic force, and the position of the driving ring 8 is limited through the limiting mechanism. When the limiting mechanism cancels the limitation of the driving ring 8, the first elastic member 15 drives the convex block 21 to move in the vertical direction, thereby generating an effect of driving the driving ring 8 to move and canceling the lock.

[0030] Furthermore, a positioning portion 14 is formed by the outer ring surface of the driving ring 8 being recessed inward. The positioning portion 14 and the outer ring surface of the driving ring 8 form a fold angle, which is convenient for the subsequent limiting mechanism to limit the position of the driving ring 8.

[0031] Furthermore, the limiting mechanism includes a rotating plate 10 and a second elastic member 16. The shape of the rotating plate 10 is bent downward in the middle. The rotating plate 10 is rotatably arranged in the inner cavity of the positioning cavity 2. The rotation axis of the rotating plate 10 is located in the direction away from the second elastic member 16 at the bent portion. A limiting block 11 capable of being clamped with the positioning portion 14 is arranged on the rotating plate 10. The second elastic member 16 is arranged in the inner cavity of the positioning cavity 2 and the top end is in contact with the bottom of the rotating plate 10. Before locking, the second elastic member 16 is compressed by the rotating plate 10 to generate an elastic force. When the driving ring 8 rotates and the limiting block 11 moves to the positioning portion 14, the elastic force of the second elastic member 16 makes one end of the rotating plate 10 where the limiting block 11 is located move upward to the fold angle to position the position of the driving ring 8.

[0032] Further, one end of the rotating plate 10 penetrates to the outside of the installation rear shell 1. A lower through hole 19 for one end of the rotating plate 10 to penetrate to the outside is formed on the surface of the installation rear shell 1. A connecting handle 13 is arranged at one end of the rotating plate 10. Anti-slip friction lines are arranged on the surface of the connecting handle 13. And through the arrangement of the connecting handle 13, it is more convenient to control the rotation of the rotating plate 10, so that the other end of the rotating plate 10 moves upward or downward. When the other end of the rotating plate 10 moves downward, it means that the limiting block 11 is engaged with the positioning portion 14. And in the case of needing to release the locking, the connecting handle 13 drives one end of the rotating plate 10 to move upward, the rotating plate 10 rotates and the other end moves downward, and the limiting block 11 is separated from the positioning portion 14, achieving the effect of releasing the locking.

[0033] Under normal circumstances, after the throttle handle has penetrated into the inner cavity of the through groove 5 and is in contact with the inner wall surface of the limiting ring 12, when it is necessary to lock and position the throttle handle, by pressing down the fixed handle 9 to drive the driving ring 8 to rotate, through the cooperation of the positioning rod 6 and the first sliding groove 22 and the cooperation of the auxiliary rod 20 and the second sliding groove 23, the driving ring 8 drives the two locking members 7 to rotate, and then the ends of the two locking members 7 with the auxiliary rod 20 approach each other, pressing tightly against the limiting ring 12, so as to limit the limiting ring 12 and the throttle handle located in the limiting ring 12, and the limiting is further strengthened by the friction force of the limiting ring 12.

[0034] When it is necessary to release the locking and positioning of the throttle handle, since the fixed handle 9 moves downward, the driving ring 8 drives the convex block 21 to move downward, and the first elastic member 15 is squeezed to generate an elastic force. And the rotating plate 10 makes the limiting block 11 snap into the positioning portion 14 through the elastic force of the second elastic member 16 to position the driving ring 8. Therefore, by moving the connecting handle 13 upward to drive the rotating plate 10 to rotate, the end close to the limiting block 11 moves downward. After the limiting block 11 is separated from the positioning portion 14, the convex block 21 moves upward through the elastic force of the first elastic member 15, the driving ring 8 rotates, and through the cooperation of the positioning rod 6 and the first sliding groove 22 and the cooperation of the auxiliary rod 20 and the second sliding groove 23, the two locking members 7 are reset, and the pressing against the limiting ring 12 is cancelled.

[0035] The above are only the preferred embodiments of the present invention and are not used to limit the present invention. It should be pointed out that for those of ordinary skill in the art in this technical field, without departing from the technical principle of the present invention, several improvements and modifications can still be made, and these improvements and modifications should also be regarded as the protection scope of the present invention.
