Description

Technical Field

[0001] The utility model relates to the technical field of gear locking, in particular to a gear locking structure. Background Art

[0002] A gear is a mechanical part with teeth on the rim that can continuously mesh to transmit motion and power. It is widely used in mechanical transmission and the entire mechanical field. When the gear stops transmitting motion, the gear itself may continue to move due to inertia. This situation will affect the use of the gear set and needs to be stopped in time. For example, the Chinese utility model with patent number CN218935110U discloses a gear locking structure, which controls the clamping plate and limit pin set on the surface of the gear roller sleeve by embedding and installing a micro electromagnet, and realizes the function of locking the gear when the gear stops operating by opening and closing the electromagnet.

[0003] The above utility model still has certain problems for users. During its use, the pin that plays a limiting role needs to be manually removed when the gear resumes its movement, which is not convenient for releasing the lock of the gear later. At the same time, it is not easy to judge the gear operation status by controlling the locking device through the electromagnet, resulting in the card plate in the device that stops the gear from moving causing additional bumps and wear to the gear when preventing the gear from continuing to move. Utility Model Content

[0004] In view of the above technical problems, the utility model provides a gear locking structure, which is characterized by comprising an operating structure and a braking structure, wherein the braking structure is installed on the operating structure.

[0005] The braking structure is composed of a limit gear A, a limit gear B, a face gear, a through shaft, a baffle, a support frame, and a handle. The limit gear A is installed on the top of the left end bracket of the support frame, and the limit gear A is meshed with the face gear. The limit gear B is installed on the top of the right end bracket of the support frame, and the limit gear B is meshed with the face gear. A through shaft is installed at a central hole of a horizontal plate on one side of the support frame, a handle is installed on the top of one side of the through shaft, the other end of the through shaft passes through the face gear, and a baffle is installed on the back of the face gear.

[0006] The operating structure comprises a power screw, a cylindrical gear, a transmission gear A and a transmission gear B. A cylindrical gear is installed on the top of the power screw, the cylindrical gear meshes with the transmission gear A, a through-shaft is installed in a central hole of the transmission gear A, a transmission gear B is installed on the right side of the transmission gear A, and a through-shaft is installed in a central hole of the transmission gear B.

[0007] Specifically, one end of the limit gear A is meshed with the face gear, and the other end opposite thereto is meshed with the transmission gear B; one end of the limit gear B is meshed with the face gear, and the other end opposite thereto is meshed with the transmission gear B.

[0008] Specifically, the through shaft passes through the transmission gear A, the transmission gear B, the face gear, and the central opening of the baffle in sequence.

[0009] Beneficial effects of the utility model:

[0010] The utility model is provided with a transmission gear A and a transmission gear B, both of which are meshed with the limit gear B. When the transmission gear A operates normally, the through shaft can drive the support frame and the handle to rotate together with the gear set. When the gear locking brake is required, it is only necessary to hold the handle to stop the through shaft and the support, thereby stopping the limit gear A and the limit gear B from rotating, and then driving the transmission gear A and the transmission gear B to stop rotating, so as to achieve a braking effect. The overall structure is simple and the operation is convenient. At the same time, the additional collision and wear of the gear set caused by braking are reduced, and it is easy to release the locked state and restore the movement of the gear set.

[0014] The technical solution of the utility model will be described clearly and completely below in conjunction with the accompanying drawings. Obviously, the described embodiments are part of the embodiments of the utility model, not all of the embodiments.

In addition, the terms "first", "second", and "third" are used for descriptive purposes only, and cannot be understood as indicating or implying relative importance.

[0016] In the description of the present utility model, it should be noted that, unless otherwise clearly specified and limited, the terms "installed", "connected" and "connected" should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be indirectly connected through an intermediate medium, or it can be the internal connection of two components. For ordinary technicians in this field, the specific meanings of the above terms in the present utility model can be understood according to specific circumstances. In addition, the technical features involved in the different embodiments of the present utility model described below can be combined with each other as long as they do not conflict with each other.

[0017] Example 1

[0018] like Figure 1 and Figure 2 As shown, a cylindrical gear 2 is installed at the head of the power screw 1, and the cylindrical gear 2 is meshed with the transmission gear A. The central opening of the transmission gear A3 passes through the through shaft 8, and a transmission gear B4 is installed on the right side of the transmission gear A3 on the through shaft 8. A face gear 7 is installed on the right side of the transmission gear B4 on the through shaft 8. A baffle 9 is installed on the back of the gear 7 on the through shaft 8. The through shaft 8 passes through the opening of the cross plate of the support frame 10, and a handle 11 is installed on the top of the through shaft 8. A limit gear A5 is installed on the top of the left end bracket of the support frame 10, and one end of the limit gear A5 is meshed with the face gear 7, and the other end is meshed with the transmission gear B4. A limit gear B6 is installed on the top of the right end bracket of the support frame 10, and one end of the limit gear B6 is meshed with the face gear 7, and the other end is meshed with the transmission gear B4.

[0019] Example 2

[0020] During use, when the gear set is operating normally, the power screw 1 provides operating power for the transmission gear A3, and the cylindrical gear 2 at the top of the power screw 1 engages with the transmission gear A4 to rotate, driving the through shaft 8 to rotate, and at the same time drives the transmission gear B5 to rotate, and then drives the limit gear A5 and the limit gear B6 to rotate, and then drives the support frame 10 to rotate.

[0021] When gear locking is required, the power screw 1 stops rotating and no longer provides power to the transmission gear A3. Holding the handle 11, the support frame 10 and the through shaft 8 stop rotating, thereby stopping the limit gear A5 and the limit gear B6, and then stopping the transmission gear A and the transmission gear B, thereby achieving a gear braking effect. When it is necessary to resume the movement of the transmission gear A3, release the handle 11, and resume the rotation of the power screw 1 to resume the movement of the gear set.
