Description

Technical Field

[0001] This invention relates to a maintenance tool for diesel vehicle filters, and more particularly to a belt-type filter removal and installation tool. Background Technology

[0002] The installation and removal of diesel vehicle filters is an essential part of automotive repair and maintenance. Some existing filter removal tools are belt-driven. These tools have a circular tooth at the end of the handle to grip the filter cartridge wall. A lifting lug is attached to the side of the circular tooth via a pin. The lower end of the lug is connected to a belt, and the other end of the belt loops around the lug to form a ring that tightens around the filter cartridge. Turning the handle applies torque to the filter cartridge, twisting it to remove or install it. The problem with this tool is that the engagement between the circular tooth and the belt is not ideal, causing the belt to slip on the filter cartridge. Even adding a round tooth welded to the circular tooth does not solve the problem. Therefore, it is necessary to improve this type of belt-driven filter removal tool. Summary of the Invention

[0003] The purpose of this invention is to address the above-mentioned problems by proposing a new belt-type filter element disassembly and assembly tool, which has a reasonable structure, does not slip, and has high disassembly and assembly efficiency, thereby overcoming the problems of the existing technology.

[0004] The objective of this invention is achieved by the following means.

[0005] A belt-type filter cartridge installation and removal tool has a handle, a lifting lug, and a belt. The handle is characterized by having an anti-slip block pinned to its end. The anti-slip block has teeth on its lower side and a belt hole in its middle. The lifting lug is pinned to the side of the anti-slip block. The lower end of the lifting lug is connected to the belt. The belt passes through the belt hole of the anti-slip block and then through the lifting lug to form a ring, which is then fitted onto the filter cartridge and tightened to allow the handle to apply torque.

[0006] The handle end is equipped with a connecting block that becomes part of the handle, and the connecting block has a pin hole for the anti-slip block and the lifting lug to connect.

[0007] The connecting block is made of metal, and the handle is made of wood, plastic, or / and metal.

[0008] The connection between the connecting block and the handle can be a threaded connection, a bolted connection, or a welded connection.

[0009] The connecting block and the handle can be made as one piece.

[0010] The connection between the belt and the lifting lug is also a pin joint.

[0011] The belt is a toothed belt.

[0012] The teeth of the anti-slip block are distributed on the left and right sides of the belt hole, with the tips of the teeth tilted outwards and each side having 2-4 teeth.

[0013] The anti-slip strip belt hole also has teeth on both the front and back sides, with the tips of the teeth tilted to one side.

[0014] The anti-slip pin holes protrude symmetrically on both sides of the belt hole, making the anti-slip block form a saddle shape.

[0015] This invention is used as follows: To use, wrap the belt around the filter cartridge and pull the handle in one direction. The belt will tighten around the filter cartridge, and the anti-slip strip's teeth will engage to prevent slippage. The torque from the handle will then be applied to the cartridge, causing it to twist. To loosen the belt, remove it from the filter cartridge, rotate it 180 degrees, and then re-wrap it. Simply pull the handle in the opposite direction.

[0016] Regardless of whether the belt passes through the top or bottom of the belt hole, the anti-slip block will be pressed against the filter cartridge by the belt. The more you turn the handle, the tighter it is pressed. This effectively prevents slippage and ensures that the torque of the handle is fully applied to the filter cartridge, avoiding empty turning and thus improving the efficiency of disassembly and assembly.

[0017] The present invention has a reasonable structure, is non-slip, quick to assemble and disassemble, has high efficiency, and is easy to use. Attached Figure Description

Detailed Implementation

[0028] The invention will be further described below with reference to the accompanying drawings.

[0029] like Figure 1-9 As shown, the handle 4 is a straight rod, basically the same as existing ones, made of materials such as plastic, metal, and wood. The upper end of the handle can directly mount the anti-slip block 1 and the lug 7 via the anti-slip pin 5, or a connecting block 2 can be added to the upper end of the handle, effectively extending the handle. Mounting pin holes (201 and 202) for the anti-slip block and lug 4 are drilled on the connecting block, and the anti-slip block and lug 4 are mounted via the anti-slip pin 5 and the lug pin 6. For easier gripping, its lower section is designated as the grooved section 9.

[0030] Belt 3 is a toothed belt and can be ordered commercially. The belt is mounted on the lifting lug via belt pin 8. The structure and shape of the lifting lug are similar to those of existing filter cartridge belt removal and installation tools.

[0031] The anti-slip block 1 has an overall shape that is approximately saddle-shaped. It has a raised anti-slip block pin hole 103 on the upper side, a belt hole 104 in the center, and left teeth 101 and right teeth 102 on the lower side of the belt hole. Teeth may also be present on the front and back sides of the belt hole.

[0032] When installing the anti-slip block using a connecting block, the tooth setting during belt threading is as follows: Figure 8 As shown; the tooth setting when the belt is threaded under is as follows Figure 9 As shown.

[0033] Components and designations not mentioned are as described above.

[0034] This invention is also applicable to the disassembly and assembly of threaded objects with cylindrical structures, such as oil filters. Therefore, applying this invention to the disassembly and assembly of such objects falls within the scope of protection of this invention.
