Description

Technical Field

[0001] The utility model relates to the field of auxiliary disassembly components, in particular to an auxiliary component used for tire disassembly. Background Art

[0002] In the field of automobile maintenance, tire removal and installation is one of the common maintenance tasks. However, traditional tire removal methods often rely on manual operations, such as using tools such as jacks to lift the vehicle, and then manually removing the tire from the wheel hub. This process is not only time-consuming and labor-intensive, but also in some cases, due to the design limitations of the jack or other auxiliary tools, it is often difficult to complete the tire removal work efficiently and safely. At present, there are many tire removal auxiliary tools on the market, but many of them have a common problem: the inability to flexibly adjust the telescopic distance of the insert, resulting in the inability to effectively embed the tire to lift the tire in certain situations. Specifically, the inserts of these tools are usually fixed in length or have a limited adjustment range, and cannot adapt to tires of different models, different tire sizes, and different degrees of wear. Utility Model Content

[0003] The utility model provides an auxiliary component for tire disassembly, which overcomes the shortcomings described in the background technology.

[0004] The technical solution adopted by the utility model to solve its technical problem is:

[0005] An auxiliary component for tire removal, comprising a sleeve, a hexagonal rod, a screw, a transmission tube, and an anti-collision bearing, wherein the screw penetrates into the hexagonal rod to form a threaded connection therewith, the transmission tube is connected to the end of the screw, and the sleeve is sleeved outside the hexagonal rod, and the anti-collision bearing is sleeved outside the screw and abuts against the inner side surface of the sleeve, so that the telescopic length of the hexagonal rod can be adjusted by rotating the screw;

[0006] A second clamping plate is provided on the side of the hexagonal rod away from the transmission tube, and the second clamping plate extends vertically upward. A first clamping plate is provided on the side of the sleeve close to the second clamping plate. The upper part of the first clamping plate is inclined and the first clamping plate is inclined toward the second clamping plate.

[0007] A better technical solution: a hexagonal guide rail and a tubular hole are provided in the sleeve, the cross section of the hexagonal guide rail is hexagonal and fits with the outer side surface of the hexagonal rod, and the tubular hole is located at the end of the hexagonal guide rail, and the anti-collision bearing is sleeved on the corresponding surface of the screw and the tubular hole.

[0008] A preferred technical solution: an insert is provided on the side of the screw rod away from the second bolt clamping plate, and the transmission tube is sleeved outside the insert, and the cross section of the insert is polygonal, and the inner end contour of the transmission tube coincides with the cross section of the insert.

[0009] Compared with the prior art, this technical solution has the following advantages:

[0010] When the screw rotates, it pushes or pulls the hexagonal rod to move axially in the sleeve, thereby changing the extension length of the hexagonal rod; the sleeve provides a sliding track for the hexagonal rod to ensure its smooth movement. At the same time, the hexagonal guide rail in the sleeve further enhances the stability and accuracy of the sliding. When the hexagonal rod is extended to an appropriate length, the second clamping plate at its end and the first clamping plate on the sleeve together form a clamping structure. The inclined design of the first clamping plate helps to better adapt to the shape of the tire edge, while the second clamping plate provides vertical support and clamps the tire mounted outside the wheel hub when the first clamping plate retracts into the second clamping plate to facilitate tire replacement.

[0022] like Figures 1 to 5As shown, the utility model proposes an auxiliary component for tire disassembly, including a sleeve 1, a hexagonal rod 2, a screw 3, a transmission tube 4, and an anti-collision bearing 5. The screw 3 penetrates into the hexagonal rod 2 to form a threaded connection therewith, and the transmission tube 4 is connected to the end of the screw 3, and the sleeve 1 is sleeved outside the hexagonal rod 2, and the anti-collision bearing 5 is sleeved outside the screw 3 and abuts against the inner side surface of the sleeve 1, so that the telescopic length of the hexagonal rod 2 can be adjusted by rotating the screw 3. The screw 3 in the component serves as an adjusting component, which converts rotational motion into linear motion. A threaded connection is formed between the screw 3 and the hexagonal rod 2. Therefore, when the screw 3 rotates, it will push or pull the hexagonal rod 2 to move axially in the sleeve 1, thereby changing the extended length of the hexagonal rod 2; the sleeve 1 provides a sliding track for the hexagonal rod 2 to ensure its smooth movement. At the same time, the hexagonal guide rail 11 in the sleeve 1 further enhances the stability and accuracy of sliding. When the hexagonal rod 2 is extended to an appropriate length, the second clamping plate 21 at its end and the first clamping plate 13 on the sleeve 1 form a clamping structure together. The inclined design of the first clamping plate 13 helps to better adapt to the shape of the tire edge, while the second clamping plate 21 provides vertical support force, and when the first clamping plate 13 is retracted into the second clamping plate 21, the tire mounted outside the wheel hub is clamped to facilitate tire replacement.

[0023] A second clamping plate 21 is provided on the side of the hexagonal rod 2 away from the transmission tube 4, and the second clamping plate 21 extends vertically upward. A first clamping plate 13 is provided on the side of the sleeve 1 close to the second clamping plate 21, and the upper part of the first clamping plate 13 is arranged in an inclined shape, and the first clamping plate 13 is inclined toward the second clamping plate 21.

[0024] Furthermore, the sleeve 1 is provided with a hexagonal guide rail 11 and a tubular hole 12. The cross-section of the hexagonal guide rail 11 is hexagonal and fits with the outer side surface of the hexagonal rod 2, and the tubular hole 12 is located at the end of the hexagonal guide rail 11. The anti-collision bearing 5 is sleeved on the corresponding surface of the screw 3 and the tubular hole 12. The design of the entire auxiliary component takes into account the stability and safety of the operation. For example, the provision of the anti-collision bearing 5 reduces the friction and wear between the screw 3 and the sleeve 1, and at the same time provides the necessary buffering effect to prevent damage caused by hard contact. The transmission tube 4 is tightly matched with the insert 31 of the screw 3 to ensure the effective transmission of the rotational force and improve the accuracy and reliability of the adjustment process.

[0025] A preferred technical solution: an insert 31 is provided on the side of the screw rod 3 away from the second bolt clamping plate 21, and the transmission tube 4 is sleeved outside the insert 31, and the cross-section of the insert 31 is polygonal, and the inner end contour of the transmission tube 4 coincides with the cross-section of the insert 31.

[0026] The above description is only a preferred embodiment of the present invention, and therefore cannot be used to limit the scope of implementation of the present invention. That is, equivalent changes and modifications made according to the patent scope of the present invention and the contents of the specification should still fall within the scope covered by the present invention.
