Description

Technical Field

[0001] This utility model relates to the field of tire pry bar technology, and in particular to an anti-slip adjustable tire removal pry bar. Background Technology

[0002] A tire pry bar is a hand tool specifically designed for tire removal and installation. It primarily uses leverage to help users separate or install tires from rims. It is typically made of metal, possessing a certain strength and rigidity. The overall structure includes a handle for applying force, a lever for transmitting force, and a pry head for inserting into the gap between the tire and rim.

[0003] In existing technologies, when removing a tire, a pry bar is needed to gradually pry its edge off the rim. Specifically, the pry bar head is inserted into the gap between the tire and the rim, and leverage is applied to disengage the tire bead from the rim edge, thus easily removing the tire completely from the rim.

[0004] However, when using a pry bar to remove or install tires on an electric vehicle, and because the pry bar may be too short to apply force when it enters the rim, it cannot be flexibly adjusted according to the actual situation. The length cannot be adjusted according to the actual gap depth and rim size, making it difficult for the tip of the pry bar to accurately apply force to the separation point between the tire and the rim. It is easy for the pry bar to slip during the prying process, which may scratch the rim surface coating. Utility Model Content

[0005] The purpose of this invention is to address the shortcomings of existing technologies and provide an anti-slip adjustable tire removal pry bar.

[0007] In a preferred embodiment, the anti-slip mechanism includes a handle, an anti-slip sleeve is provided on the outer side of the handle, and the outer side of the handle is fixedly connected to the inner surface of the anti-slip sleeve.

[0008] In a preferred embodiment, an anti-disengagement loop is provided on the top side of one end of the handle, and the top side of one end of the handle is fixedly connected to the end of the anti-disengagement loop. One end of the handle is also fixedly connected to one end of the auxiliary pry bar.

[0009] In a preferred embodiment, a spring is provided on one side of the locking plate, and one side of the locking plate is fixedly connected to one end of the spring. A center plate is provided on the other end of the spring, and the other end of the spring is fixedly connected to one side of the center plate. A threaded rod is provided on the inner side of the center plate, and the bottom end of the threaded rod is rotatably connected to the inner side of the center plate.

[0010] In a preferred embodiment, a baffle is provided on the outer side of the threaded rod, and the outer side of the threaded rod is threadedly connected to the inner wall of the baffle. One end of the baffle contacts one side of the locking plate, and a drive cylinder is provided at the top end of the threaded rod, and the top end of the threaded rod is fixedly connected to the bottom end of the drive cylinder.

[0011] In a preferred embodiment, the inner side of the center plate is slidably connected to one side of the baffle, and the bottom end of the center plate is fixedly connected to the inner wall of the connecting plate.

[0014] Compared with the prior art, the advantages and positive effects of this utility model are as follows:

[0015] 1. By pulling the secondary pry bar, the overall length is increased. During this process, the locking plate, under the action of the spring, moves back and slides out from the locking plate in an undulating manner to slide and engage with the groove on the inner side of the main pry bar. By using a tool to rotate the drive cylinder, the threaded rod rotates and the baffle moves down from its original position. The baffle will then be located between the two locking plates, so that the locking plate is not affected by the elasticity of the spring and will resist the locking plate and restrict its sliding. Through the stable length of the main pry bar and the secondary pry bar, the locking state obtains a suitable operating length, allowing the operator to apply force in the best way.

[0026] Example 1

[0027] like Figure 1 - Figure 5As shown, this utility model provides a technical solution: an anti-slip adjustable tire removal pry bar, including an adjustment mechanism 1, an anti-slip mechanism 2 at one end of the adjustment mechanism 1, the adjustment mechanism 1 including a main pry bar 11, a secondary pry bar 13 provided on the inner wall of the main pry bar 11, the inner wall of the main pry bar 11 contacting one end of the secondary pry bar 13, a connecting plate 12 provided on one end of the secondary pry bar 13, one end of the secondary pry bar 13 being fixedly connected to one end of the connecting plate 12, a locking plate 16 provided on the inner wall of the connecting plate 12, the inner wall of the connecting plate 12 being slidably connected to the outer side of the locking plate 16, a protrusion on one side of the locking plate 16 being slidably engaged with a recess on the inner wall of the main pry bar 11, a spring piece 17 provided on one side of the locking plate 16, one side of the locking plate 16 being fixedly connected to one end of the spring piece 17, a center plate 18 provided on the other end of the spring piece 17, the other end of the spring piece 17 being fixedly connected to one side of the center plate 18, and the inner side of the center plate 18 being fixedly connected to the center plate 18. A threaded rod 19 is provided, with the inner side of the center plate 18 rotatably connected to the bottom end of the threaded rod 19. A baffle 110 is provided on the outer side of the threaded rod 19, and the outer side of the threaded rod 19 is threadedly connected to the inner wall of the baffle 110. One end of the baffle 110 contacts one side of the locking plate 16. A drive cylinder 111 is provided at the top end of the threaded rod 19, and the top end of the threaded rod 19 is fixedly connected to the bottom end of the drive cylinder 111. The inner side of the center plate 18 is vertically slidably connected to one side of the baffle 110, and the bottom end of the center plate 18 is fixedly connected to the inner wall of the connecting plate 12. A sub-plate 14 is provided on the inner side of the main pry bar 11, and the inner side of the main pry bar 11 is fixedly connected to one end of the sub-plate 14. The outer side of the sub-plate 14 is slidably connected to the inner wall of the connecting plate 12. A sub-rod 15 is provided at one end of the auxiliary pry bar 13, and one end of the auxiliary pry bar 13 is fixedly connected to one end of the sub-rod 15. The outer side of the sub-rod 15 is slidably connected to the inner wall of the main pry bar 11.

[0028] In this embodiment, the anti-slip adjustable tire removal pry bar is designed with a main pry bar 11 and a secondary pry bar 13, which are connected as a whole. A U-shaped space is formed on the inner wall of the main pry bar 11, and a connecting plate 12 is designed within this space. One end of the connecting plate 12 is fixed to one end of the secondary pry bar 13. When dealing with tires of different sizes, a center plate 18 is designed on the inner wall of the connecting plate 12, located at the middle of the inner wall of the connecting plate 12, while the left and right sides... Each side is designed with a spring clip 17, and the components connected to the spring clip 17 are all identical. A locking plate 16 is fixed to one end of the spring clip 17. The locking plate 16 has a protrusion on one side and can slide on the inner wall of the connecting plate 12. At the same time, a groove corresponding to the protrusion of the locking plate 16 is opened on the inner side of the main pry bar 11. Therefore, by pulling the auxiliary pry bar 13, the distance between the main pry bar 11 and the auxiliary pry bar 13 increases, and the overall length increases. During this process, the locking plate 16 will be locked under the action of the spring clip 17. The lever continuously retracts and slides out of the locking plate 16 in an undulating manner. Its protrusions alternately engage with different slots as the position of the corresponding slot on the inner side of the main pry bar 11 changes, progressively locking the extension and retraction lengths of the main pry bar 11 and the auxiliary pry bar 13. A baffle 110 is designed on the inner wall of the center plate 18, and a threaded rod 19 is installed at the middle of the inner side of the center plate 18. A drive cylinder 111 is fixed to the top of the threaded rod 19. Therefore, by using a tool to rotate the drive cylinder 111, the threaded rod 19 rotates, causing... The baffle 110 is moved down from its original position and will be located between the two locking plates 16. This allows the locking plates 16 to be resisted and restricted from sliding by the elasticity of the spring 17, thereby ensuring that the main pry bar 11 and the auxiliary pry bar 13 can be further fixed after the length is increased. In this way, when disassembling tires of different sizes, the operating length can be obtained by the stable length locking state of the main pry bar 11 and the auxiliary pry bar 13, allowing the operator to apply force in the best way.

[0029] A sub-plate 14 is fixed in the U-shaped space of the main pry bar 11. A connecting plate 12 is on the outside of the sub-plate 14. This ensures that the connecting plate 12 remains connected to the main pry bar 11 when the auxiliary pry bar 13 is separated from the main pry bar 11. It also ensures that the rigidity between the main pry bar 11 and the auxiliary pry bar 13 is not insufficient due to separation. At the same time, an auxiliary rod 15 is installed at one end of the auxiliary pry bar 13. The auxiliary rod 15 is located on the inner wall of the main pry bar 11. The auxiliary rod 15 also increases the rigidity and prevents deformation due to relative movement or separation of the two. This ensures that the force can be stably transmitted when prying force is applied to the tire.

[0030] Example 2

[0031] like Figure 1As shown, the anti-slip mechanism 2 includes a handle 21, an anti-slip sleeve 22 is provided on the outside of the handle 21, the outside of the handle 21 is fixedly connected to the inner surface of the anti-slip sleeve 22, an anti-disengagement loop 23 is provided on the top side of one end of the handle 21, the top side of one end of the handle 21 is fixedly connected to one end of the anti-disengagement loop 23, and one end of the handle 21 is fixedly connected to one end of the auxiliary pry bar 13.

[0032] In this embodiment, a handle 21 is installed at one end of the auxiliary pry bar 13. The handle 21 is in the shape of a horizontal column. The original pry bar handle 21 is a one-piece molded plate. The horizontal column handle 21 design improves the comfort of grip and the convenience of exerting force. Compared with the original one-piece molded plate handle 21, it fits the hand grip posture better. In addition, an anti-slip sleeve 22 is installed on the outside of the handle 21. The anti-slip sleeve 22 can increase the friction between the hand and the handle 21 and prevent the tool from falling off due to hand slippage during operation. At the same time, an anti-disengagement loop 23 is fixed on the top side of the handle 21. When the hand grips the anti-slip sleeve 22, the anti-disengagement loop 23 is located on the back of the hand, which further forms a reverse restraint to prevent the hand from slipping off the end of the handle 21 during the exertion of force. Thus, the safety of grip can be ensured when performing high-intensity operations such as prying tires.

[0033] like Figure 1 - Figure 5 As shown:

[0034] By pulling the secondary pry bar 13, the distance between the main pry bar 11 and the secondary pry bar 13 increases, and the overall length also increases. During this process, the locking plate 16, under the action of the spring piece 17, will continuously retract and slide out from within the locking plate 16 in an undulating manner. Its protrusions will alternately embed into different slots as the position of the corresponding slot on the inner side of the main pry bar 11 changes, locking the extension and retraction lengths of the main pry bar 11 and the secondary pry bar 13 segment by segment. A baffle 110 is designed on the inner wall of the center plate 18, and a threaded rod 19 is installed at the middle of the inner side of the center plate 18. The top of the threaded rod 19 is fixed with a drive cylinder 111. Therefore, by making Rotating the drive cylinder 111 with a tool causes the threaded rod 19 to rotate, causing the baffle 110 to move downwards from its original position. The baffle 110 will then be positioned between the two locking plates 16, allowing the locking plates 16 to be resisted and restricted from sliding by the elasticity of the spring 17. This makes it easier to apply force when disassembling tires of different sizes. Secondly, when the secondary pry bar 13 separates from the main pry bar 11, the connecting plate 12 always remains connected to the main pry bar 11, ensuring that the rigidity between the main pry bar 11 and the secondary pry bar 13 is not insufficient due to separation. Additionally, a secondary rod 15 is installed at one end of the secondary pry bar 13, which also serves to increase rigidity.

[0035] A handle 21 is installed at one end of the secondary pry bar 13. The handle 21 is in the shape of a horizontal column. The horizontal column design of the handle 21 improves the comfort of gripping and the convenience of exerting force. An anti-slip sleeve 22 is installed on the outside of the handle 21. The anti-slip sleeve 22 can increase the friction between the hand and the handle 21. At the same time, an anti-disengagement loop 23 is fixed on the top side of the handle 21. When the hand grips the anti-slip sleeve 22, the anti-disengagement loop 23 is located on the back of the hand, which further forms a reverse restraint.

[0036] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of the present utility model without departing from the technical solution of the present utility model shall still fall within the protection scope of the technical solution of the present utility model.
