Description

Technical Field

[0001] This utility model relates to the field of fastener technology, and in particular to a height-adjustable adapter for motorcycle rearview mirrors. Background Technology

[0002] With the acceleration of urbanization, electric vehicles, as an environmentally friendly and convenient means of transportation, have been widely used globally. To improve riding safety, electric vehicles are usually equipped with rearview mirrors so that drivers can observe traffic conditions behind them. However, in actual use, due to vehicle design and ergonomics, the rearview mirrors of some electric vehicles are installed too low, making it difficult for drivers to obtain a good field of vision. To solve this problem, height-adjustable adapters for electric vehicle rearview mirrors have appeared on the market, improving the driver's field of vision by increasing the height of the rearview mirrors. However, the height of currently available height-adjustable adapters is fixed and cannot be adjusted; only different models of height-adjustable adapters can be replaced.

[0003] Therefore, it is necessary to improve upon the shortcomings of the existing technologies mentioned above. Summary of the Invention

[0004] The technical problem to be solved by this utility model is to provide a height-adjustable adapter for motorcycle rearview mirrors, which addresses the shortcomings of the prior art and solves the problem that the height of the height-adjustable adapter is not adjustable in the prior art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a height-adjustable adapter for a motorcycle rearview mirror, comprising a body, the body being divided into a first part and a second part. The first part has a screw at one end and a receiving groove at the other end that can be axially slidably connected to the second part. The second part has an internal threaded hole at one end away from the screw and several radially evenly distributed protrusions at the other end. The inner wall of the receiving groove has movable grooves that can adapt to the radial protrusions and move along the axial direction of the first part. An axial protrusion is formed between the several movable grooves. Each axial protrusion is axially arrayed with several snap-fit ​​grooves. The radial protrusions can be rotated and snapped into the snap-fit ​​grooves. A limiting mechanism is provided between the radial protrusions and the snap-fit ​​grooves to restrict the deflection between them.

[0006] Using the above technical solution, when assembling the adapter, align the radial protrusion of the second part with the movable groove in the receiving groove of the first part and slide it into the appropriate depth. Then, rotate the first or second part to make the radial protrusion of the second part snap into the snap-fit ​​groove of the first part. After rotating to the appropriate position, the relative deflection of the first and second parts is restricted by the limiting mechanism. When it is necessary to adjust the height of the adapter, rotate the first or second part again to release the restriction of the limiting mechanism and make the radial protrusion of the first part disengage from the snap-fit ​​groove and rotate into the movable groove. Then, readjust the axial relative position of the first and second parts, and rotate the first or second part again to make the radial protrusion of the second part snap back into the snap-fit ​​groove of the first part and be re-limited by the limiting mechanism. In summary, the adapter can be adjusted to the appropriate height in multiple positions according to actual needs, with high flexibility, and there is no need to purchase multiple models of adapters separately.

[0007] A further configuration of the above technical solution is as follows: the limiting mechanism includes a blind hole at one end of the radial protrusion, a spring and a ball installed in the blind hole, a retaining ring fixedly connected to the opening of the blind hole, and an arc-shaped groove on the inner wall of the locking groove that can abut and fit with the ball. One end of the spring abuts against the bottom of the blind hole and the other end abuts against the ball. The middle part of the retaining ring is provided with a through hole with a smaller diameter at one end and a larger diameter at the other end near the arc-shaped groove. The ball can extend out of the surface of the radial protrusion through the through hole and be locked into the arc-shaped groove.

[0008] Using the above technical solution, when the radial protrusion is aligned with the locking groove and rotated into the locking groove, it continues to rotate until the side wall of the locking groove abuts against the ball and squeezes the ball. The ball then squeezes the spring, causing the spring to contract. Continuing to rotate until the ball slides to the arc-shaped groove, the ball is locked into the arc-shaped groove under the elastic force of the spring. This limits the deflection between the radial protrusion and the locking groove, meaning that the first and second parts are less likely to deflect, thus improving stability. Similarly, releasing the limit can be achieved simply by reversing the operation.

[0009] A further provision of the above technical solution is that a recessed groove is provided at the opening of the blind hole, and the retaining ring is installed in the recessed groove with an interference fit.

[0010] By using the above technical solution, the retaining ring is installed in the recess with an interference fit, which not only limits the movement of the balls but also prevents protrusion interference and makes the installation simple and aesthetically pleasing.

[0011] A further provision of the above technical solution is that: a limiting block is provided at the end of the snap-fit ​​groove away from the arc-shaped groove, which can abut against the side of the radial protrusion.

[0012] By adopting the above technical solution, the radial protrusion is limited away from the limiting mechanism by the limiting block, and the simultaneous limiting of both ends of the radial protrusion is achieved, which further improves the stability.

[0013] A further feature of the above technical solution is that the cylindrical surface of the second part is provided with a plurality of marking grooves for marking positions.

[0014] By adopting the above technical solution, the marking groove on the cylindrical surface of the second part can be used as a reference to check the relative position of the marking groove and the upper edge of the first part when adjusting the height of the adapter, making it easier to align the radial protrusion with the snap-fit ​​groove.

[0015] A further provision of the above technical solution is that: the first split body near the screw end and the second split body near the internal thread hole end are both provided with hexagonal disassembly and assembly parts for use with tools during disassembly and assembly.

[0016] By adopting the above technical solution, the adapter can be more easily disassembled and assembled with the help of tools through the hexagonal disassembly and assembly parts provided on the first and second parts.

[0017] The beneficial effects achieved by this utility model are: it can adjust the adapter to a suitable height in multiple gears according to actual needs, has high flexibility, and does not require the purchase of multiple models of adapters. Attached Figure Description

Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] like Figure 1-4 As shown, a height-adjustable adapter for a motorcycle rearview mirror includes a body 1, which is divided into a first part 2 and a second part 3. One end of the first part 2 has a screw 4, and the other end has a receiving groove 20 that can slide axially with the second part 3. The second part 3 has an internal threaded hole 30 at one end away from the screw 4, and four circumferentially evenly distributed radial protrusions 5 at the other end. The inner wall of the receiving groove 20 has movable grooves 21 that can adapt to the radial protrusions 5 and move axially along the first part 2. An axial protrusion 22 is formed between the four movable grooves 21. Each axial protrusion 22 has six locking grooves 23 arranged axially. The radial protrusions 5 can be rotated into the locking grooves 23. A limiting mechanism is provided between the radial protrusions 5 and the locking grooves 23 to restrict deflection between them. The limiting mechanism includes a blind hole 50 at one end of the radial protrusion 5, a spring 6 and a ball 7 installed in the blind hole 50, and a... The retaining ring 8 is fixedly connected to the opening of the hole 50, and the inner wall of the snap-fit ​​groove 23 has an arc-shaped groove 230 that can abut against the ball 7. One end of the spring 6 abuts against the bottom of the blind hole 50 and the other end abuts against the ball 7. The middle of the retaining ring 8 is provided with a through hole 80 with a smaller diameter at one end and a larger diameter at the other end near the arc-shaped groove 230. The ball 7 can extend out of the surface of the radial protrusion 5 through the through hole 80 and be snapped into the arc-shaped groove 230. The opening of the blind hole 50 is provided with a recess 51, and the retaining ring 8 is installed in the recess 51 with an interference fit. The end of the snap-fit ​​groove 23 away from the arc-shaped groove 230 is provided with a limiting block 24 that can abut against the side of the radial protrusion 5. The cylindrical surface of the second part 3 is provided with five marking grooves 31 for marking the position. The end of the first part 2 near the screw 4 and the end of the second part 3 near the opening of the internal thread hole 30 are both provided with hexagonal disassembly and assembly parts 11 for use with tools during disassembly and assembly.

[0025] In the above embodiment, when assembling the adapter, after aligning the radial protrusion 5 of the second part 3 with the movable groove 21 in the receiving groove 20 of the first part 2 and sliding it into the appropriate depth, rotate the first part 2 or the second part 3 so that the radial protrusion 5 of the second part 3 is engaged in the snap-fit ​​groove 23 of the first part 2. After rotating to the appropriate position, the spring 6 acts to engage the ball bearing 7 in the arc-shaped groove 230 to restrict the relative deflection of the first part 2 and the second part 3. When it is necessary to adjust the height of the adapter, rotate the first part 2 or the second part 3 again to allow the ball bearing 7 to slide out of the arc-shaped groove 230. After that, the radial protrusion 5 of the first split 2 is further disengaged from the snap-fit ​​groove 23 and rotated into the movable groove 21. Then, after readjusting the relative axial positions of the first split 2 and the second split 3, the first split 2 or the second split 3 is rotated again so that the radial protrusion 5 of the second split 3 is re-engaged into the snap-fit ​​groove 23 of the first split 2 and repositioned into the arc-shaped groove 230 by the ball bearing 7. In summary, the beneficial effect achieved by this embodiment is that the adapter can be adjusted to a suitable height in six positions according to actual needs, with high flexibility, and no need to purchase multiple models of adapters.
