Technical Field

[0001] The utility model relates to the technical field of gear tight-fitting shifting rod structures, in particular to a gear tight-fitting shifting rod structure. Background Art

[0002] The gear tight-fitting lever structure is a device that can clamp the half gear through a rivet column. When using the gear tight-fitting lever structure, that is, when the half gear needs to be clamped, the rivet column is directly passed through the half gear, so that the half gear can be clamped well.

[0003] The inventors have found in their daily work that the gear-fitting lever structure still has at least the following problems: when using the gear-fitting lever structure, that is, when the half gear needs to be stuck, the rivet stud is directly passed through the half gear, which can well clamp the half gear. However, in actual use, after the rivet stud is passed through the half gear, the rivet stud is not fixed inside the half gear, which will affect the rivet stud's clamping of the half gear to a certain extent.

[0006] The effect achieved by the above components is: when using the limit device, in the process of passing the rivet post through one side of the half gear, one side of the rivet post squeezes the inclined surface opened on the top of the extrusion block, thereby stretching the first spring; when the rivet post completely passes through the half gear, the first spring contracts, so that the extrusion block is squeezed on one side of the rivet post, which can effectively limit the rivet post inside the half gear.

[0007] Preferably, a groove is provided on one side of the inclined surface, a round rod is fixedly connected to the inner wall of the groove, and a roller is rotatably sleeved on the surface of the round rod.

This can well adjust the length of the rivet column, making it easier to set the gear tight-fitting lever structure at different positions.

[0015] Preferably, a second damping rod is fixedly connected to the bottom of the inner wall of the storage groove, and the end of the second damping rod away from the storage groove is fixedly connected to one end of the sliding rod.

When the limiting device is used, in the process of passing the rivet post through one side of the half gear, one side of the rivet post squeezes the inclined surface opened on the top of the extrusion block, thereby stretching the first spring.

When the gear tight-fitting lever structure is used, that is, when the half gear 1 needs to be stuck, the rivet column 2 is directly passed through the half gear 1, so that the half gear 1 can be stuck well.

[0028] Reference Figure 2 and Figure 3 The limiting device 4 includes a first damping rod 401, one end of the positioning frame 3 is fixedly connected to the first damping rod 401, the end of the first damping rod 401 away from the positioning frame 3 is fixedly connected to the extrusion block 403, the surface of the first damping rod 401 is provided with a first spring 402, one end of the first spring 402 is fixedly connected to one side of the positioning frame 3, the end of the first spring 402 close to the first damping rod 401 is fixedly connected to the extrusion block 403, and a slope 404 is provided on one side of the extrusion block 403. 4, when the rivet stud 2 passes through one side of the half gear 1, one side of the rivet stud 2 squeezes the inclined surface 404 on the top of the squeezing block 403, thereby stretching the first spring 402. When the rivet stud 2 completely passes through the half gear 1, the first spring 402 contracts, so that the squeezing block 403 is squeezed on one side of the rivet stud 2, which can effectively restrict the rivet stud 2 inside the half gear 1. A groove 405 is formed on one side of the inclined surface 404, and a round rod 406 is fixedly connected to the inner wall of the groove 405. The surface of the round rod 406 is rotatably sleeved with a roller 407. When the rivet column 2 squeezes the inclined surface 404, the roller 407 is driven to rotate, so that the rivet column 2 can pass through the inclined surface 404 well. A blocking block 408 is inserted and slidably penetrated on one side of the positioning frame 3. A second spring 410 is fixedly connected to one side of the blocking block 408. The end of the second spring 410 close to the positioning frame 3 is fixedly connected to one side of the positioning frame 3. The blocking block 408 passes through one side of the positioning frame 3, and then the blocking block 408 is squeezed. On one side of the rivet post 2, the locking block 408 is pulled toward the positioning frame 3 by the second spring 410, so that the locking block 408 is squeezed on one side of the rivet post 2. In this way, the rivet post 2 can be restricted inside the positioning frame 3 by the locking block 408. The side of the locking block 408 close to the positioning frame 3 is fixedly connected to a rubber block 409, and the rubber block 409 is slidably inserted into one side of the positioning frame 3. After the locking block 408 passes through the positioning frame 3, the rubber block 409 is squeezed to the side of the rivet post 2 away from the top of the rivet post 2.

[0029] Reference Figure 4The adjusting device 5 includes a sliding rod 502, a receiving groove 501 is provided on one side of the rivet column 2, and the inner wall of the receiving groove 501 is slidably connected to the sliding rod 502. A bolt 503 is inserted through a thread on one side of the rivet column 2. When the adjusting device 5 is used, the sliding rod 502 is manually controlled to slide on the inner wall of the receiving groove 501. When the sliding rod 502 moves to a suitable position inside the receiving groove 501, the bolt 503 is manually controlled to rotate, thereby causing the bolt 503 to be squeezed on one side of the rivet column 2. This can well adjust the length of the rivet column 2, thereby facilitating the setting of the gear-matching lever structure at different positions. A second damping rod 504 is fixedly connected to the bottom of the inner wall of the receiving groove 501, and the end of the second damping rod 504 away from the receiving groove 501 is fixedly connected to one end of the sliding rod 502. A third spring 505 is sleeved on the surface of the second damping rod 504. One end is fixedly connected to one side of the inner wall of the receiving groove 501, and the end of the third spring 505 close to the second damping rod 504 is fixedly connected to one end of the sliding rod 502. The third spring 505 squeezes the rivet column 2 in the direction away from the receiving groove 501, thereby facilitating the control of the rivet column 2 to slide outward inside the receiving groove 501. The bottom of the inner wall of the receiving groove 501 is fixedly connected with a connecting rope 506, and the end of the connecting rope 506 away from the receiving groove 501 is fixedly connected to one end of the sliding rod 502. The sliding rod 502 is pulled toward the bottom of the receiving groove 501 through the connecting rope 506. This can prevent the sliding rod 502 from completely sliding out of the receiving groove 501. The surface of the sliding rod 502 is fixedly connected with a rubber sleeve 507, which is sleeved on the surface of the bolt 503. The rubber sleeve 507 is sleeved on the surface of the bolt 503, thereby avoiding accidental touching of the bolt 503 to a certain extent.

[0030] Working principle: when using the gear tight matching lever structure, that is, when the half gear 1 needs to be stuck, the rivet post 2 is directly passed through the half gear 1, so that the half gear 1 can be well stuck. When using the limit device 4, in the process of passing the rivet post 2 through one side of the half gear 1, one side of the rivet post 2 squeezes the inclined surface 404 opened on the top of the extrusion block 403. When the rivet post 2 squeezes the inclined surface 404, the roller 407 is driven to rotate, so that the rivet post 2 can pass through the inclined surface 404 well, thereby stretching the first spring 402. When the rivet post 2 completely passes through the half gear 1, the first spring 402 contracts, which allows the extrusion block 403 to be squeezed on one side of the rivet post 2, and the blocking block 408 is passed through the side of the positioning frame 3, and then the blocking block 408 is squeezed on one side of the rivet post 2. The blocking block 408 is pulled toward the direction close to the positioning frame 3 by the second spring 410, and the rubber block 409 is squeezed to the rivet post. 2 is away from the side of the top of the rivet stud 2, so that the rivet stud 2 can be well restricted inside the half gear 1. When using the adjustment device 5, the sliding rod 502 is manually controlled to slide on the inner wall of the receiving groove 501, and the rivet stud 2 is pressed in the direction away from the receiving groove 501 by the third spring 505, thereby facilitating the control of the rivet stud 2 to slide outward inside the receiving groove 501. When the sliding rod 502 moves to a suitable position inside the receiving groove 501, the bolt 503 is manually controlled to rotate, so that the bolt 503 is pressed against one side of the rivet stud 2. In this way, the length of the rivet stud 2 can be well adjusted, and the gear tight fitting lever structure can be easily set at different positions. The rubber sleeve 507 is sleeved on the surface of the bolt 503, thereby avoiding accidental contact with the bolt 503 to a certain extent. The sliding rod 502 is pulled toward the bottom of the receiving groove 501 by the connecting rope 506, so as to prevent the sliding rod 502 from completely sliding out of the receiving groove 501.

[0031] It should be noted that all damping rods in this case are retractable dampers that can absorb energy during the retraction and extension process.
