Description

Technical Field

[0001] The utility model belongs to the technical field of automobile maintenance, and in particular relates to a multifunctional tool for disassembling and assembling tire accessories of household vehicles and removing air conditioner valve needles. Background Art

[0002] Car maintenance is a general term for car maintenance and repair. It involves using technical means to troubleshoot a broken car, identify the cause, and then take appropriate measures to eliminate the problem and restore it to a certain performance and safety standard.

[0003] Since there are many types of automotive tools, and tools such as tire accessory disassembly and assembly and air-conditioning valve needles are small and numerous, they are relatively scattered to carry and difficult to find and use, resulting in the problem that conventional tire accessory disassembly and assembly and air-conditioning valve needle tools are relatively low in practicality.

[0004] For this reason, we propose a multifunctional tool for disassembling and assembling tire accessories of household vehicles and disassembling air-conditioning valve needle to solve the above problems. Utility Model Content

[0005] The utility model aims to solve the problem of low practicability of conventional tools for disassembling and assembling tire accessories and air conditioner valve needles, and proposes a multifunctional tool for disassembling and assembling tire accessories and removing air conditioner valve needles for household vehicles.

[0006] In order to achieve the above purpose, the present invention adopts the following technical solutions:

[0007] A multifunctional tool for disassembling and assembling tire accessories for household vehicles and removing air conditioner valve needles, comprising a deflation rod, a hooked wrench and an elastic clamp. The lower portion of the hooked wrench is buckled inside the deflation rod, the lower portion of the elastic clamp is slidably sleeved on the hooked wrench, and the elastic clamp is in active contact with the inner wall of the deflation rod. Aim the elastic clip at the nut of the target wheel, then press the elastic clip inward to shrink the elastic clip, embed the elastic clip in the nut groove, and then further tighten the elastic clip to clamp the column nut, and then take out the nut; when it is necessary to use a hook wrench to screw the car air conditioner nut, insert the elastic clip into the bleed rod, so that the bleed rod acts on the elastic clip to close the elastic clip until the hook wrench protrudes to the upper side of the elastic clip, screw the car air conditioner nut with the hook wrench, insert the hook wrench into the leather block of the wheel, and hook out the leather block with the hook wrench; insert the lower end of the bleed rod into the wheel air nozzle to release the air in the tire; it is convenient to perform maintenance operations on commonly used areas of the car.

[0008] Preferably, a bolt is threadedly mounted on the hook wrench, and the bolt is used to block the elastic clamp, thereby conveniently limiting the upward sliding range of the elastic clamp.

[0009] Preferably, the deflation rod comprises a shell and a deflation needle, wherein the deflation needle is fixedly connected to the lower end of the shell. The deflation needle is operated by holding the shell and inserted into the air nozzle of the wheel to facilitate deflation of the air in the tire.

[0010] Preferably, the hook wrench includes an operating block, a guide rail, and an inserting block. The upper end of the operating block is provided with a slot, the outer end of the operating block is provided with a hooking slot, the lower end of the operating block is fixedly connected to the upper end of the guide rail, and the inserting block is fixedly connected to the lower end of the guide rail. The slot is clamped on the air conditioner nut. When the hook wrench rotates, the slot drives the nut to rotate. When the operating block is inserted into the target leather block, the hooking slot hooks into the leather block, thereby increasing the friction between the hook wrench and the leather block.

[0011] Preferably, the hook spanner further comprises a spring buckle, which is installed in the insert block. The insert block is inserted into the interior of the housing and the spring buckle is engaged with the housing to increase the stability of the deflation rod and the hook spanner after docking.

[0012] Preferably, the elastic clamp includes a hook block, a spring plate, and a sliding sleeve. The spring plate is symmetrically fixed to the upper end of the sliding sleeve, and the hook block is fixed to the upper end of the spring plate. By pinching the upper portion of the spring plate, the elastic clamp is pushed downward to retract into the deflation rod. By pulling the upper portion of the spring plate upward, the elastic clamp is re-extended, making it easy to operate the elastic clamp.

[0013] Preferably, the elastic clamp further comprises anti-slip teeth, which are symmetrically fixedly connected to the upper part of the elastic sheet. The anti-slip teeth are used to increase the friction between the hand and the elastic clamp, making it easier to pinch the elastic clamp.

[0014] In summary, the technical effects and advantages of the utility model are:

[0015] 1. Aim the elastic clip at the nut of the target wheel, then press the elastic clip inward to shrink the elastic clip, embed the elastic clip in the nut groove, and then further tighten the elastic clip to clamp the column nut, and then take out the nut; when it is necessary to use a hook wrench to screw the car air conditioner nut, insert the elastic clip into the deflation rod, so that the deflation rod acts on the elastic clip to close the elastic clip until the hook wrench protrudes to the upper side of the elastic clip, screw the car air conditioner nut with the hook wrench, insert the hook wrench into the leather block of the wheel, and hook out the leather block with the hook wrench; insert the lower end of the deflation rod into the wheel air nozzle to release the air in the tire; it is convenient to perform maintenance operations on commonly used areas of the car, thereby improving practicality.

[0016] 2. Clamp the card slot on the air conditioner nut. When the hook wrench rotates, the card slot drives the nut to rotate. After the operating block is inserted into the target leather block, use the hook slot to hook into the leather block to increase the friction of the hook wrench on the leather block.

[0017] 3. Insert the plug into the inside of the shell and use the spring buckle to snap it into place with the shell to increase the stability of the bleed rod and the hook wrench after docking.

[0018] 4. Pinch the upper part of the spring and push the elastic clip downward to retract the elastic clip into the deflation rod. Pull the upper part of the spring upward to extend the elastic clip again, making it easier to operate the elastic clip. BRIEF DESCRIPTION OF THE DRAWINGS
