Description

Technical Field

[0001] The utility model relates to the technical field of fasteners, in particular to a stabilizing bolt for a booster. Background Art

[0002] Bolts are a commonly used fastener, mainly used to connect two or more parts, and are fastened by the combination of threads and nuts. There are many types of bolts, which are classified according to different characteristics such as head shape, thread type, material and performance grade. Common bolt types include hexagonal head bolts, square head bolts, bolts for reamed holes, special purpose bolts, etc. Special connectors sometimes require high-strength bolts, which have the ability to withstand higher loads.

[0003] Most of the existing booster stabilizing bolts use two nuts to fix the connecting foot at one end of the booster stabilizing bolt. The two nuts have the function of adjusting the position of the connecting foot. However, the booster stabilizing bolt needs to withstand the intermittent pressure applied by the connecting foot, which may cause the nut on the booster stabilizing bolt to loosen. When the nut is loosened, the position will move, causing the position of the connecting foot to move, and ultimately the booster stabilizing bolt cannot start the booster. In order to solve this technical problem, the utility model proposes a booster stabilizing bolt. Utility Model Content

[0004] The main purpose of the utility model is to provide a stabilizing bolt for a booster, which can effectively solve the problems mentioned in the background technology.

[0022] In order to make the technical means, creative features, objectives and effects achieved by the present invention easier to understand, the present invention is further described below in conjunction with specific implementation methods.

[0023] like Figure 1-6 As shown, a stabilizing bolt for a booster includes a bolt body 1 and a nut 2. The nut 2 is threadedly connected to the threaded section of the bolt body 1. The nut 2 is used to limit the moving position of the connecting foot and provide supporting force to maintain the stability of the connecting foot. A sliding groove 3 is provided on the inner side of the bolt body 1. The inner wall of the sliding groove 3 is slidingly connected to a support seat 4. The sliding groove 3 is used to provide space for the support seat 4 to move and guide the direction of movement of the support seat 4. The inner wall of the support seat 4 is slidingly connected to a sliding rod 6. One end of the sliding rod 6 is connected to the inner top wall of the sliding groove 3, and the other end of the sliding rod 6 is connected to the inner bottom wall of the sliding groove 3. The sliding rod 6 provides supporting force for the moving position of the support seat 4 to maintain the stability of the support seat 4 during movement.

[0024] A spring 7 is sleeved on the outside of the slide rod 6, one end of the spring 7 is connected to the inner top wall of the slide groove 3, and the other end of the spring 7 is connected to the inner bottom wall of the slide groove 3. The spring 7 provides elastic thrust for the support seat 4, and the support seat 4 pushes the gear disc 1 8 to always contact the gear disc 2 9.

[0025] The upper surface of the support seat 4 is connected to the toothed disc 1 8, and the lower surface of the nut 2 is connected to the toothed disc 2 9. The outer surface of the toothed disc 2 9 contacts the outer surface of the toothed disc 1 8. Both the toothed disc 1 8 and the toothed disc 2 9 have latching teeth. Through the staggered contact between the latching teeth, mutual obstruction is formed to limit the rotation of the nut 2.

[0026] The interior of the support seat 4 is provided with a positioning mechanism 5, which is used to adjust the position of the support seat 4. When the toothed disc 1 8 and the toothed disc 2 9 need to be separated, the support seat 4 is pulled to drive the toothed disc 1 8 to move its position. After the toothed disc 1 8 moves to its position, it disengages from the contact with the toothed disc 2 9, and then the positioning block 502 contacts the positioning groove 503 to limit the movement of the support seat 4. The positioning mechanism 5 includes a guide rod 501, the outer surface of the guide rod 501 is slidably connected to the inner wall of the support seat 4, and one end of the guide rod 501 is connected to the positioning block 502. The inner side of the slide rod 6 is provided with a positioning groove 503, and the positioning groove 503 is adapted to the positioning block 502. The positioning block 502 contacts the positioning groove 503 to form a block on the support seat 4, limiting the movement of the support seat 4. The positioning groove 503 and the positioning block 502 both have an inclined angle, which makes it easier for the positioning block 502 to disengage from the contact with the positioning groove 503.

[0027] The outer surface of the guide rod 501 is connected to a support block 504, and the outer surface of the support block 504 is slidably connected to the inner wall of the support seat 4. A spring 2 505 is sleeved on the outside of the guide rod 501, and one end of the spring 2 505 is connected to one side of the support block 504, and the other end of the spring 2 505 is connected to the inner wall of the support seat 4. The support block 504 provides support force for the guide rod 501 to maintain the stability of the guide rod 501. When the guide rod 501 drives the support block 504 to move its position, the support block 504 compresses the spring 2 505, and the compressed spring 2 505 provides power for the positioning block 502 to reset.

[0028] The other end of the guide rod 501 is rotatably connected to a pull rod 506, and the outer surface of the pull rod 506 is connected to a stop block 507. One side of the stop block 507 contacts one side of the support seat 4, and the inner side of the support seat 4 is provided with multiple stop grooves 508, and the multiple stop grooves 508 are arranged at equal distances, and the stop grooves 508 are adapted to the stop block 507. When the positioning block 502 needs to be separated from the positioning groove 503, the guide rod 501 is moved by pulling the pull rod 506, and the guide rod 501 simultaneously drives the positioning block 502 to move its position. After the positioning block 502 moves its position, it disengages from the positioning groove 503, and at the same time, the stop block 507 passes through the support seat 4 through the stop groove 508. When the pull rod 506 is rotated to drive the stop block 507 to move its position, the stop block 507 deviates from the stop groove 508, and is blocked by the support seat 4 to reset the stop block 507, while keeping the positioning block 502 at a distance from the positioning groove 503.

[0029] It should be noted that in actual use of the device, the nut 2 is first rotated to the set position of the connecting foot to form a support for the connecting foot, and then the toothed disc 1 8 is brought into contact with the toothed disc 2 9. The elastic support force provided by the spring 1 7 keeps the toothed disc 1 8 and the toothed disc 2 9 in contact without external force. When the position of the nut 2 needs to be adjusted, the toothed disc 1 8 is first separated from the toothed disc 2 9. First, the guide rod 501 is pulled to move the position by the pull rod 506. When the guide rod 501 moves, the positioning block 502 is disengaged from the positioning groove 503. 1 moves to a new position, and at the same time, the spring 2 505 is compressed by the support block 504, and then the support seat 4 is pulled downward to drive the gear disc 1 8 to separate from the gear disc 2 9. After a distance is generated between the gear disc 1 8 and the gear disc 2 9, the pull rod 506 is released, and then the spring pushes the support block 504 to move. The support block 504 drives the positioning block 502 to contact the positioning groove 503 through the guide rod 501. After the positioning block 502 contacts the positioning groove 503, it forms a block to the support seat 4, limiting the movement of the support seat 4. After the gear disc 2 9 loses the blockage of the gear disc 1 8, the nut 2 can be rotated to adjust its position.
