Description

Technical Field

[0001] This utility model relates to the field of tire technology, specifically to a tire lever. Background Technology

[0002] When a bicycle or other vehicle's tire leaks air, it is necessary to pry open the outer tire and remove the inner tube to repair or replace it.

[0003] Existing tire pry bar structures typically have a pry head at the end of a handle. This pry head is inserted between the tire and the rim to pry out the tire sidewall. To facilitate tire installation, the pry head also has a guide mechanism to guide the tire sidewall into the mounting groove of the rim. As the pry head moves along the rim, it gradually guides the tire sidewall into the mounting groove. However, the mounting groove of the rim has a certain depth, and the portion of the tire sidewall outside the mounting groove corresponds to the depth of the groove. Therefore, it is difficult for the tire sidewall located on the outer side of the rim to cross over the outer side of the rim and enter the mounting groove, making it difficult for users to install the tire using the pry head.

[0031] Please see Figure 1 One embodiment of this utility model provides a tire lever, including: a handle 10 and a tire lever head 20;

[0032] The handle 10 is connected to the tire lever head 20. The tire lever head 20 is provided with a rim pressing part 21, a tire support part 22 and a tire guide part 23. The rim pressing part 21 extends in a preset direction. The tire support part 22 and the rim pressing part 21 are located on adjacent sides of the tire lever head 20. The tire support part 22 and the tire guide part 23 are arranged sequentially in a preset direction. The tire guide part 23 has a tire hook part 231 formed on it. The side of the tire guide part 23 facing the tire support part 22 has a tire guide part 232 for guiding part of the structure of the tire 40 from the tire support part 22 to the side of the tire lever head 20 near the rim pressing part 21.

[0033] The working principle of the tire lever according to one embodiment of this utility model is explained below:

[0034] When tire 40 needs to be removed, insert the tire hook 231 between tire 40 and rim 30 to pry out the tire sidewall of tire 40. At this time, the tire guide 23 is attached to rim 30. Then, the user operates the tire pry head 20 by holding the handle 10 and moving it along rim 30 in the same direction as the preset direction. The part of tire sidewall of tire 40 located in the mounting groove 31 of rim 30 will be driven by the tire guide 23 and disengaged from the mounting groove 31 of rim 30, thereby removing tire 40.

[0035] When tire 40 needs to be installed, the rim pressing part 21 is pressed against the outside of the rim 30, and the tire guide 23 is arranged on the outside of the rim 30 to near the groove of the mounting groove 31 of the rim 30. The tire support part 22 is also located on the outside of the rim 30 and can lift the tire sidewall of the tire 40 to a position closer to the groove of the mounting groove 31 of the rim 30. The user operates the tire pry head 20 by holding the handle part 10 and moves it along the rim 30 in a direction opposite to the preset direction. The tire sidewall of the tire 40 will gradually reach the tire support part 22, then contact the tire guide part 232, and finally be guided by the tire guide part 232 to move from the outside of the rim 30 toward the mounting groove 31 of the rim 30, thereby facilitating the installation of the tire 40.

[0036] In some alternative embodiments, a limiting protrusion 221 is provided on the tire support 22. The limiting protrusion 221 extends in a preset direction, and an avoidance notch 222 for avoiding the passage of the tire 40 is formed between the end of the limiting protrusion 221 facing the tire guide 23 and the tire guide 23.

[0037] When the tire 40 needs to be installed, the limiting protrusion 221 hooks onto the inside of the tire sidewall of the tire 40, thereby preventing the tire sidewall of the tire 40 from directly contacting the rim 30. Then the tire sidewall of the tire 40 can pass through the clearance notch 222 and then move toward the mounting groove 31 of the rim 30.

[0038] In some alternative embodiments, the tire guide portion 232 includes a guide arc portion 2321, which extends gradually away from the side of the tire lever head 20 with the tire support portion 22 in a predetermined direction. When the tire 40 is installed, the tire sidewall and the tire bead of the tire 40 abut against the guide arc portion 2321, and the tire lever head 20 can effectively guide the tire sidewall and the tire bead of the tire 40 to move toward the mounting groove 31 of the rim 30 when it moves. In this embodiment, the clearance notch 222 is located between the guide arc portion 2321 and the limiting protrusion 221.

[0039] In some alternative embodiments, the tire guide portion 232 further includes a guide surface 2322 connected to the guide arc portion 2321. The guide surface 2322 extends gradually away from the side of the tire head 20 with the rim 30 support portion in a preset direction. After the tire sidewall and tire edge of the tire 40 are guided by the guide arc portion 2321 to deviate towards the mounting groove 31 of the rim 30, the tire head 20 moves and the structure of the tire 40 is further guided by the guide surface 2322 to move towards the mounting groove 31 of the rim 30.

[0040] In some optional embodiments, the tire guide 23 is provided with a tire pressing part 233. The tire pressing part 233 and the tire support part 22 are respectively located on opposite sides of the tire guide 23 in a preset direction. The tire pressing part 233 can press against the sidewall and edge of the tire 40, thereby providing a support position for the tire 40 during the process of removing or installing the tire 40, which helps to maintain the position of the tire 40 and prevent the tire 40 from shifting.

[0041] In some optional embodiments, a rim positioning groove 234 extending in a preset direction is formed on the tire pressing part 233, and the tire guide part 232 extends to one side of the rim positioning groove 234. When removing the tire 40, after the tire hook part 231 pries out the tire sidewall of the tire 40, the rim positioning groove 234 of the tire guide part 23 adheres to the rim 30. At this time, the rim positioning groove 234 is positioned and engaged with the rim 30. When the user operates the tire prying head 20 by holding the handle part 10 and moving it along the rim 30 in the same direction as the preset direction, the rim positioning groove 234 moves along the rim 30. In this embodiment, the inner wall of the rim positioning groove 234 abuts against the outer side of the rim and the edge of the mounting groove 31, respectively. The two abutting positions facilitate the user to apply force to make the rim positioning groove 234 adhere tightly to the rim 30. When installing tire 40, due to its elasticity, after tire 40 is pressed onto tire pressing part 233, part of tire 40 will extend into rim positioning groove 234. By restricting rim positioning groove 234, the position of tire 40 is restricted, improving the stability of tire 40's position during tire removal or installation. In this embodiment, the guide surface 2322 of tire guide part 232 extends to one side of rim positioning groove 234.

[0042] In some alternative embodiments, a positioning hook groove 235 is formed between the tire guide 23 and the rim pressing part 21. When the tire 40 is installed, the positioning hook groove 235 can engage with the edge of the mounting groove 31 of the rim 30, so that the rim pressing part 21 can fit more closely to the rim 30. The positioning hook groove 235 restricts the tire head 10 from being squeezed out by the elasticity of the tire 40, and the tire head 20 is more stable when moving along the rim 30.

[0043] In some alternative embodiments, a guide groove 2331 for positioning and engaging with the rim 30 is formed on the rim pressing portion 21. The guide groove 2331 extends in a preset direction and can engage with the structure on the rim 30 for positioning and engaging, thereby making the rim pressing portion fit more closely with the rim 30 and improving the stability of the tire lever 20 during the process of removing or installing the tire 40.

[0044] In some optional embodiments, the handle 10 is provided with a storage groove 11 and a tire pry bar 12. The tire pry bar 12 is detachably stored in the storage groove 11, which allows for convenient storage of the tire pry bar 12 and good portability. When the tire 40 is tight and difficult to pry, the tire pry bar 12 can be removed from the handle 10. The user can hold the tire pry bar 12 with both hands to pry the tire 40, thereby making it easier for the user to apply more force to pry the tire 40 and avoiding the situation where the tire hook 231 on the tire pry head 20 is difficult to pry the tire 40. After the tire pry bar 12 pries out the tire sidewall, the tire pry head 10 is then arranged and installed relative to the rim 30 and the tire 40 to remove the tire 40.

[0045] To facilitate the removal of the tire pry bar 12, in some optional embodiments, the storage slot 11 has an end opening 111 and a side opening 112. The end opening 111 is located at the end of the handle 10 away from the tire pry head 20, and the side opening 112 is located on one side of the handle 10 and communicates with the end opening 111. A user can insert their finger into the side opening 112 and press it against the tire pry bar 12, thereby moving the finger toward the end opening 111 and moving the tire pry bar 12 toward the end opening 111, making it easy for the user to remove the tire pry bar 12 from the storage slot 11. In this embodiment, the tire pry bar 12 engages with the storage slot 11, thereby facilitating quick and easy fixation of the tire pry bar 12 in the storage slot 11.

[0046] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
