Description

Technical Field

[0001] The utility model belongs to the technical field of filter wrenches, and in particular relates to a bowl-shaped filter wrench. Background Art

[0002] The oil filter, also known as the oil filter, is used to remove impurities such as dust, metal particles, carbon deposits and soot particles in the oil to protect the engine. During maintenance, a specific wrench is usually required to remove the oil filter.

[0003] A Chinese patent with publication number CN209478075U discloses a bowl-shaped filter disassembly and assembly wrench, comprising a bowl-shaped sleeve, a rotating sleeve head is fixedly installed at the center position of the upper end surface of the bowl-shaped sleeve, a circle of internal grooves is provided on the inner wall of the bowl-shaped sleeve, a rotating hole is provided inside the rotating sleeve head, the rotating sleeve head is connected to a rotating rod through the rotating hole, the rotating rod is connected to a clamping head through a rotating shaft pin, and a movable telescopic cavity running through both sides is provided inside the rotating rod above the rotating shaft pin, and a telescopic limit marble is provided at each end of the movable telescopic cavity.

[0004] Although the bowl-shaped filter disassembly and assembly wrench is provided with a folding rod, a hexagonal socket and a through pin, the disassembly and assembly wrench can be used conveniently at multiple angles and is suitable for use in places with small surrounding space; the filter can be disassembled and assembled by directly twisting the rotating socket through the hexagonal socket; foreign matter on the filter can be easily removed, which is simple and practical.

[0005] However, the above-mentioned bowl-shaped filter disassembly and assembly wrench is found to have the following defects during actual use:

[0006] The rotating rod and the folding rod are connected by a rotating shaft pin, and can be used vertically or horizontally according to the on-site conditions. However, the position of the front end of the folding rod on the rotating rod cannot be changed, so that the distance between the front end of the folding rod and the bowl-shaped sleeve cannot be adjusted, resulting in it still being difficult to use for removing the filter in places with small surrounding space. Utility Model Content

[0007] The utility model aims to provide a bowl-shaped filter wrench to solve the technical defects that the existing disassembly and assembly wrenches cannot be adjusted during use and are extremely inconvenient to use in a limited space.

[0008] In order to achieve the above purpose, the utility model provides the following technical solutions:

[0009] A bowl-type filter wrench, comprising:

[0010] A bowl-shaped sleeve matched with the filter, the bottom of which has a regular polygonal inner cavity;

The sliding rod slides through the adjustment through groove, and the U-shaped connecting seat is fixedly installed at both ends of the sliding rod;

[0012] A telescopic handle, which is installed on the outer side of the U-shaped connecting seat and is perpendicular to the sliding rod.

[0013] As a further solution of the present invention, the telescopic handle includes a hollow outer sleeve rod, a connecting rod and a locking sleeve. A plurality of notches are formed at the front end of the hollow outer sleeve rod, and an external thread is formed on the outer side surface of the front end of the hollow outer sleeve rod. One end of the connecting rod is inserted into the front end inside of the hollow outer sleeve rod, and the other end of the connecting rod is fixedly installed on the outer side surface of the U-shaped connecting seat. The locking sleeve is threadedly sleeved on the outside of the front end of the hollow outer sleeve rod. When the locking sleeve is tightened, the front end of the hollow outer sleeve rod can contract under the action of the plurality of notches and clamp the connecting rod.

[0014] As a preferred solution of the present invention, the plurality of notches are arranged at equal angles in the circumferential direction, and at least four notches are provided.

[0015] As a preferred solution of the present invention, a protective sleeve is sleeved on the outside of the rear end of the hollow outer sleeve rod.

[0016] As a further solution of the present invention, the protective sleeve is a rubber sleeve, and the outer surface of the protective sleeve is a matte surface.

[0017] As a further solution of the present invention, a reinforcing seat is fixedly installed at the connection between the center position of the top of the bowl-shaped sleeve and the connecting column.

[0018] As a preferred solution of the present invention, the bowl-shaped sleeve is a stainless steel bowl-shaped sleeve, and a ring is integrally provided on the outside of the bottom edge of the bowl-shaped sleeve.

[0019] Compared with the prior art, a bowl-shaped filter wrench provided by the present invention has the following beneficial effects:

[0020] 1. The position-adjustable connecting component in the bowl-shaped filter wrench is mainly composed of a connecting column, a sliding rod and a U-shaped connecting seat. At the same time, an adjustment through groove is formed along the length direction of the connecting column. The provided sliding rod slides through the adjustment through groove, and the U-shaped connecting seat is fixedly installed at both ends of the sliding rod. The telescopic handle is installed on the outer side of the U-shaped connecting seat, so that the distance between the front end of the telescopic handle and the bowl-shaped sleeve can be adjusted, which can be better suitable for disassembling the filter in a place with a small surrounding space;

[0021] 2. The telescopic handle provided in the bowl-shaped filter wrench can adjust its overall length under the action of the hollow outer sleeve rod, several notches, the connecting rod, and the locking sleeve. That is to say, the length of the force arm can be adjusted, so that the bowl-shaped filter wrench can be adapted to different users. BRIEF DESCRIPTION OF THE DRAWINGS
