Technical Field

[0001] This utility model relates to the field of automotive oxygen sensor disassembly and assembly tools, and in particular to a sleeve tool for disassembling and assembling automotive oxygen sensors. Background Technology

[0002] In automotive repair, oxygen sensors, as key components for monitoring engine combustion, are crucial for ensuring vehicle emissions compliance and power performance. However, the installation and removal of oxygen sensors has long faced numerous technical challenges: First, the sensor has its own wiring harness and connector, which traditional enclosed sockets cannot effectively avoid, easily damaging the harness during operation; second, the sensor is often located in confined spaces such as the engine compartment, and conventional tools are bulky, rigid, and difficult to position and apply force precisely, increasing the difficulty of the operation; third, ordinary tools are prone to heat deformation under high-temperature conditions, and their materials have poor insulation, posing a risk of short circuits or electric shock when operating near vehicle electrical circuits. Existing socket tools are mostly fully enclosed or have small openings, lacking sufficient obstacle avoidance capabilities, easily loosening the connection to the handle, and lacking high-temperature insulation properties, failing to meet the needs of installing and removing oxygen sensors with wiring harnesses in confined, high-temperature environments. Therefore, there is an urgent need for a specialized socket tool with wiring harness avoidance capabilities, suitable for operation in confined spaces, and possessing both high-temperature resistance and good insulation properties. Utility Model Content

[0003] In view of the above-mentioned shortcomings of current oxygen sensor installation and removal tools, this utility model provides a sleeve tool for installing and removing automotive oxygen sensors, which has a wire harness avoidance function, is suitable for operation in narrow spaces, and is resistant to high temperatures.

[0004] To achieve the above objectives, the embodiments of this utility model adopt the following technical solutions:

[0005] A socket tool for assembling and disassembling automotive oxygen sensors includes a socket body rod, a socket, and a socket connector connecting the socket body rod and the socket; one end of the socket is a first working end, and the socket is provided with a U-shaped clearance groove extending axially along the first working end; the other end of the socket is a first connecting end, and the first connecting end is connected to the socket connector; the socket is made of a high-temperature resistant composite insulating material.

[0006] According to one aspect of this utility model, the high-temperature resistant composite insulating material is an injection-molded engineering plastic.

[0007] According to one aspect of this utility model, the engineering plastic is polyetheretherketone or polyphenylene sulfide.

[0008] According to one aspect of the present invention, the first connecting end of the sleeve is provided with a square pin hole, and the sleeve connector is provided with a cuboid pin; the sleeve connector and the first connecting end are detachably rigidly connected by inserting the cuboid pin into the square pin hole.

[0009] According to one aspect of the present invention, the square pin hole is mainly square, and has semi-circular ear-shaped structures at its four vertices.

[0010] According to one aspect of the present invention, the sleeve main body rod includes a rod body and a sleeve handle, wherein the rod body and the sleeve handle are fixedly connected by injection molding.

[0011] According to one aspect of the present invention, the sleeve handle has at least two U-shaped grooves.

[0012] According to one aspect of the present invention, a connecting sleeve with a clearance groove is further included; one end of the connecting sleeve is a second connecting end, and a connecting blind hole is provided inside therein; the outline of the connecting blind hole matches the external shape of the first working end of the sleeve; by inserting and tightly fitting the first working end of the sleeve into the connecting blind hole, a detachable coaxial rigid connection between the connecting sleeve and the sleeve is achieved; the other end of the connecting sleeve is the second working end.

[0013] According to one aspect of this utility model, the inner wall of the second working end is provided with a stepped groove structure for adapting to a hexagonal head or a 12-corner head.

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] Example 1

[0025] like Figure 1 , Figure 2 , Figure 3 , Figure 4 As shown, a socket tool for disassembling and assembling automotive oxygen sensors includes a socket body rod 1, a socket 3, and a socket connector 2 connecting the socket body rod 1 and the socket 3. One end of the socket 3 is a first working end 33, and the socket 3 has a U-shaped clearance groove 32 extending axially along the first working end 33. The other end of the socket 3 is a first connecting end 31, which is connected to the socket connector 2. The socket 3 is made of high-temperature resistant composite insulating material. During operation, the U-shaped clearance groove 32 on the socket 3 can effectively avoid the wiring harness head of the sensor, making it easier to disassemble the sensor. The high-temperature resistant composite insulating material used in the socket 3 effectively prevents burns and electric shocks to the operator.

[0026] In practical applications, high-temperature resistant composite insulation materials are injection-molded engineering plastics.

[0027] Specifically, sleeve 3 is integrally formed from high-temperature resistant composite insulating material through injection molding.

[0028] In practical applications, engineering plastics are polyetheretherketone or polyphenylene sulfide.

[0029] Specifically, in a preferred embodiment, the material uses polyetheretherketone as the matrix resin, to which chopped glass fibers are added to enhance its mechanical strength and abrasion resistance. At the same time, a composite flame retardant is added, which not only gives it excellent insulation properties, but also allows it to maintain structural stability and performance for a long time in high-temperature environments. This effectively prevents slippage or deformation caused by high-temperature softening, and insulates against heat, protecting operators from burns and electric shocks.

[0030] In practical use, the first connecting end 31 of the sleeve 3 is provided with a square pin hole 311, and the sleeve connector 2 is provided with a cuboid pin 21; the sleeve connector 2 and the first connecting end 31 are detachably rigidly connected by inserting the cuboid pin 21 into the square pin hole 311. During assembly, the cuboid pin 21 is aligned and inserted into the square pin hole 311 to achieve a detachable rigid connection between the sleeve 3 and the sleeve connector 2, without any shaking when transmitting torque.

[0031] In practical use, the square pin hole 311 is based on a square shape, and its four vertices have semi-circular ear supports 312. The semi-circular ear supports 312 can further improve the connection reliability and facilitate insertion.

[0032] In practical use, the main sleeve rod 1 includes a rod body 11 and a sleeve handle 12, which are fixedly connected by injection molding.

[0033] Specifically, the rod body 11 is made of 45# steel and galvanized to prevent rust. The sleeve handle 12 is made of heat-resistant rubber and is molded onto one end of the rod body 11 through a secondary injection molding process, providing a comfortable and insulated grip.

[0034] In actual use, the sleeve handle 12 has at least two U-shaped long grooves 121.

[0035] Specifically, at least two U-shaped grooves 121 are provided on the outer wall of the sleeve handle 12, which increases the elastic deformation space of the sleeve handle 12, prevents slippage, and enhances the stability of the operator's grip and the force application effect.

[0036] Example 2

[0037] This embodiment adds a connecting sleeve with a fully open side to expand the applicability of the tool, based on embodiment one.

[0038] In practical use, the sleeve tool for disassembling and assembling automotive oxygen sensors described in Embodiment 1 also includes a connecting sleeve with a clearance groove; one end of the connecting sleeve is a second connecting end, and a connecting blind hole is provided inside; the outline of the connecting blind hole matches the external shape of the first working end 33 of the sleeve 3; by inserting and tightly fitting the first working end 33 of the sleeve 3 into the connecting blind hole, a detachable coaxial rigid connection between the connecting sleeve and the sleeve 3 is achieved; the other end of the connecting sleeve is the second working end.

[0039] Specifically, the connecting sleeve is also made of high-temperature resistant composite material. Coaxially connecting the connecting sleeve to sleeve 3 in Embodiment 1 effectively extends the tool's length, making it suitable for repair scenarios in deeper and narrower spaces. The clearance groove of the connecting sleeve can have different structures. In one structure, the clearance groove is a semi-open groove with the same structure as the U-shaped clearance groove 32 on sleeve 3. In another structure, the clearance groove of the connecting sleeve adopts a fully open design. When the connecting sleeve is connected to sleeve 3, its fully open side can align with the U-shaped clearance groove 32 of sleeve 3, thereby forming a continuous and unobstructed clearance channel on the wire harness side.

[0040] In practical use, the inner wall of the second working end is provided with a stepped groove structure to adapt to hexagonal or 12-pin heads.

[0041] Specifically, hexagonal heads can be hexagonal heads with opposite side dimensions of 17mm-22mm, and dodecagonal heads can be dodecagonal heads with opposite side dimensions of 19mm-24mm.

[0042] Example 3

[0043] like Figure 5 As shown, this embodiment provides another socket tool for removing and installing automotive oxygen sensors. Its structure is basically the same as socket 2 in Embodiment 1, the difference being the absence of a U-shaped clearance groove. This socket tool is suitable for removing oxygen sensors without wiring harnesses or ordinary bolts. Due to its uniform wall thickness and higher structural strength, it can be used as a standard socket, further enriching the tool's applications.

[0044] The advantages of this utility model are: the U-shaped clearance groove 32 on the sleeve 3 can effectively avoid the wire harness head of the sensor, making it easier to disassemble the sensor; the sleeve 3 is made of high temperature resistant composite insulating material, which can effectively prevent operators from being burned or electrocuted. At the same time, it can be matched with a connecting sleeve to extend the length of the sleeve and adapt to different corner heads.

[0045] The above description is merely a specific embodiment of this utility model, but the protection scope of this utility model is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this utility model should be included within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the protection scope of the claims.
