Description

Technical Field

[0001] This utility model relates to the field of sleeve structure technology, and in particular to a multi-purpose tire sleeve. Background Technology

[0002] In fields such as automotive repair, construction machinery, and heavy equipment maintenance, tire removal and bolt tightening are high-frequency operations. Traditional tools are usually single-function; for example, a regular socket wrench can only be used for bolt removal, and a tire pry bar can only be used for tire removal. This forces maintenance personnel to carry multiple tools, increasing their workload. In addition, existing tools are difficult to operate in low-light conditions, and some tools are not strong enough, making them prone to deformation or breakage with prolonged use, affecting work efficiency and safety.

[0003] Chinese patent discloses a wrench sleeve (publication number: CN 213259184 U) for use in rotating a ratchet wrench assembly. The wrench sleeve has a cylindrical body that can be fitted onto the outer edge of a rotating component. The inner wall of the cylindrical body is provided with a plurality of first locking parts and second locking parts at intervals. The first locking parts are located between two second locking parts. The sleeve is characterized by having a center defined inside. The first locking parts are arc-convex, and the second locking parts have a sloping straight surface. The end of the sloping straight surface that connects with the inner wall of the cylindrical body has an inwardly concave arc. However, this type of sleeve has a single function, poor adaptability, inconvenient operation, and insufficient durability. Therefore, a multi-purpose tire sleeve is needed. Utility Model Content

[0004] The purpose of this utility model is to solve the problems of traditional sleeve structures in the prior art, such as single function, poor adaptability, inconvenient operation and insufficient durability, and to propose a multi-purpose tire sleeve.

[0005] The technical solution adopted by this utility model to solve its technical problem is as follows: A multi-purpose tire sleeve of this utility model includes a sleeve body, characterized in that: the sleeve body includes a double-ended sleeve and a pry bar; the double-ended sleeve and the pry bar are connected by a locking structure; the double-ended sleeve includes a central connecting rod, with sleeve heads at both ends of the central connecting rod; the sleeve heads have polygonal inner holes inside, and lateral through holes on their sidewalls; the central connecting rod and the sleeve heads are coaxially connected and are integrally formed. Multi-functional integration: Combining the double-ended sleeve with the pry bar allows for both bolt installation and removal, as well as tire prying, reducing the number of tools required; Stable structure: The integrally formed design enhances the strength of the sleeve heads, preventing deformation or breakage due to prolonged use; Lateral through hole expansion function: Facilitates use with a lever, improving torque transmission capability, suitable for high-torque installation and removal scenarios.

[0006] Preferably, the pry bar has a U-shaped groove, and the U-shaped groove contains 8 to 12 LED beads arranged in a rectangular array. In low-light environments (such as at night or when working under a vehicle), the LED beads can illuminate the bolt position, improving operational accuracy; the rectangular array arrangement makes the light distribution more uniform, avoiding local dark areas that affect work efficiency.

[0007] Preferably, the pry bar has reinforcing ribs on both sides of its outer wall. These ribs improve the pry bar's resistance to bending, preventing deformation or breakage due to excessive force when prying a tire; the reinforced structure extends the tool's service life and adapts to high-intensity working environments.

[0008] Preferably, the engaging structure includes a protrusion on the outer wall of the pry bar and a groove on the outer wall of the double-ended sleeve, wherein the protrusion and the groove are interference-fitted. The engaging structure allows the double-ended sleeve and the pry bar to be quickly engaged or disengaged, facilitating switching between tool modes according to different operational needs; the interference fit ensures a tight connection between the two, preventing accidental detachment during use and improving safety.

[0009] Preferably, one end of the pry bar is provided with a handle, the handle has a hanging hole, and the outer wall of the handle is provided with an anti-slip coating. The anti-slip coating increases friction, prevents slippage during operation, and improves safety; the hanging hole design facilitates hanging and storing the tool, saves space, and avoids damage caused by random stacking.

[0010] Preferably, the sleeve body is made of high-strength alloy steel, wherein the tensile strength of the high-strength alloy steel is not less than 800MPa and the hardness is HRC 40~45. The high-strength material ensures that the sleeve is not easily deformed or damaged when disassembling and assembling high-torque bolts; the high-hardness surface enhances wear resistance, extends tool life, and reduces the need for frequent replacements.

[0011] The advantages of this utility model are:

[0012] This multi-purpose tire socket integrates bolt assembly / disassembly and tire prying functions through a modular design combining a double-ended socket and a pry bar, reducing the number of tools required and improving work efficiency. The one-piece molded intermediate connecting rod and socket head structure enhance overall strength, avoiding the loosening or breakage issues common in traditional split designs. The side through-hole design allows for the insertion of a force-adjusting rod, significantly improving torque transmission capability and making it suitable for high-torque bolt assembly / disassembly scenarios. The LED array within the U-shaped groove provides stable working illumination, solving the problem of operation in dark environments. The reinforcing rib structure greatly improves the pry bar's bending resistance, ensuring structural stability when forcefully prying the tire. The interference fit allows for quick assembly / disassembly of the double-ended socket and pry bar, adapting to different operational needs. The anti-slip handle and suspension hole optimize the human-machine interface, improving grip safety and facilitating tool storage and management. The application of high-strength alloy steel ensures the tool's wear resistance and deformation resistance under long-term high-intensity operation. Attached Figure Description
