Description

Technical Field

[0001] The utility model belongs to the technical field of disassembly tools, and in particular relates to a relay disassembly tool. Background Art

[0002] When inspecting and replacing relays, automobile maintenance personnel often encounter problems such as difficult to disassemble and easy damage of relays. Since the lower end of the relay is tightly embedded in the distribution box, it is not easy to pull it out by hand, and it often slips out of the hand, which makes the disassembly slow and inconvenient. After the relay is plugged in, there is almost no gap with other contact parts. When maintenance personnel disassemble the relay, it is affected by factors such as angle, direction, and small working space. It is also very difficult to use traditional tools such as needle-nosed pliers to quickly disassemble the relay without damage with one hand. The working space is too small, resulting in uneven contact between traditional disassembly tools and relays, different forces applied to each contact surface of the relay, and unconcentrated force, which makes the relay easily damaged during the removal process. Because the relays that need to be disassembled are of different sizes, it is necessary to replace tools of different sizes during disassembly, which is time-consuming, labor-intensive, and inefficient. Summary of the invention

[0003] The purpose of the utility model is to provide a relay disassembly tool, which is a pliers structure as a whole. The handle of the pliers body adopts a semicircular arc or a ring shape. The relay can be easily disassembled by inserting two fingers into it, overcoming the problem of narrow working space and difficult one-handed operation; elastic stretching parts such as springs are supported between the handles to open the pliers arm and keep the jaws in a naturally open state. When the maintenance personnel disassemble the relay, there is no need to stretch the jaws with effort, and the operation is more convenient and labor-saving; a pin position adjustment hole is provided at the hinge of the pliers body, and the installation position of the pin is changed through the pin position adjustment hole, and the width between the pliers arms can be easily adjusted to meet the needs of disassembling relays of different sizes, without the need to frequently replace different types of disassembly tools; the pliers arm is designed to be U-shaped, and the longer U-shaped pliers arm is convenient to extend between the relay and other contacts; the jaws are set at the top of the pliers arm and are in the shape of a flat shovel inclined inward, and the jaws are inserted into the gap between the relay and the bottom plate of the distribution box, and the relay is stuck and easily pulled up and removed. The utility model can solve the above-mentioned technical problems, has a simple structure, low production cost, and improves the disassembly efficiency of the relay.

[0004] The specific contents of the plan are as follows:

[0005] A relay disassembly tool comprises a first clamp body, a second clamp body and a pin shaft. The first clamp body and the second clamp body are hinged on the pin shaft, and a pin shaft position adjustment hole is arranged at the hinge of the first clamp body or the second clamp body.

[0006] Furthermore, the pin position adjustment hole includes a first mounting hole and a second mounting hole, the first mounting hole and the second mounting hole are connected to form a horizontal "8"-shaped through hole, and the pin limit is hinged on the first mounting hole or the second mounting hole of the pin position adjustment hole.

[0007] Furthermore, a hinge hole is provided at a hinged portion of the second clamp body or the first clamp body, and the hinge hole is a circular through hole.

[0008] The utility model is a pliers structure, comprising a first pliers body and a second pliers body, the first pliers body and the second pliers body are hinged by a pin shaft, and a pin shaft position adjustment hole is provided at the hinge of the first pliers body and the second pliers body. The pin shaft position adjustment hole comprises a first installation position hole and a second installation position hole, the first installation position hole and the second installation position hole are connected to form a horizontal "8"-shaped through hole, and the pin shaft limit is hinged on the first installation position hole or the second installation position hole of the pin shaft position adjustment hole. A hinge hole is provided at the hinge of the second pliers body or the first pliers body, and the hinge hole is a circular through hole. When disassembling a relay, maintenance personnel can choose to hinge the pin shaft limit in the hinge hole and the first installation position hole or in the hinge hole and the second installation position hole according to the size of the relay. Changing the position of the pin shaft hinged in the pin shaft position adjustment hole is to adjust the opening size of the two jaws of the first pliers body and the second pliers body to meet the needs of disassembling relays of different sizes. A hinge avoidance portion is provided on the opposite end surfaces of the hinge of the first pliers body and the second pliers body, and the hinge avoidance portion is a concave surface. The first pliers body and the second pliers body are hinged on the pin shaft, and the two hinged avoidance parts are matched and contacted to ensure that the handles, pliers arms and pliers of the first pliers body and the second pliers body after hinged connection are all in the same plane.

[0009] Furthermore, the first pliers body and the second pliers body both include a handle, a pliers arm and a jaw, the handle is the rear end portion of the hinged portion of the pliers body, and the handle is an outward-turned semicircular arc structure.

[0010] The first pliers body and the second pliers body both include a handle, a pliers arm and a jaw, and the handle is the rear end of the pliers body hinge. The handle is an outward-turned semicircular arc structure, and two fingers can be inserted into the two handles respectively to disassemble the relay. The semicircular arc structure can ensure that the fingers will not be disengaged during the disassembly process, which is convenient for operation. The handle can also be an arc structure and a ring structure, which can achieve the above effect, or even better.

[0011] Furthermore, the clamp arm is the front end part of the clamp body hinge, the two clamp arms form a U-shaped structure, the jaws are arranged at the top of the clamp arm, the jaws are an inward-inclined flat shovel-shaped structure, and the protruding parts of the two jaws are arranged opposite to each other.

[0012] The clamp arm is the front end of the hinged part of the clamp body, and the two clamp arms form a U-shaped structure. The jaws are set at the top of the clamp arm, and the jaws are flat spade-shaped structures that are tilted inward, and the protruding parts of the jaws are set opposite to each other. The clamp arm is designed as a U-shaped structure, which makes the clamp arm slender and more convenient to reach into the narrow distribution box to operate the relay than traditional tools such as needle-nosed pliers. The inward-tilted flat spade-shaped structure of the jaws enables the two jaws to clamp the gap between the bottom edge of the distribution box and the relay, and maintenance personnel can easily pull out the relay with two fingers.

[0013] Furthermore, the angle between the hypotenuse of the jaws and the jaw arms is 155 degrees to 160 degrees.

[0014] The angle between the hypotenuse of the jaws and the jaw arms is designed to be 155 degrees to 160 degrees. When the angle is greater than 160 degrees, the two jaws are too straight to hold the relay well, and the relay cannot be easily pulled out; when the angle is less than 155 degrees, the protruding parts of the two jaws are too large, and the jaws are not easy to extend into the bottom of the relay, which is also not conducive to the disassembly of the relay.

[0015] Furthermore, it also includes an elastic stretching piece, which is elastically connected between the two handles of the pliers body.

[0016] The utility model also includes an elastic stretching member, which is elastically connected between the two handles of the pliers body. The elastic stretching member is arranged between the two handles near the hinge, and plays a supporting or tightening role on the handles. When the elastic stretching member is in a supporting role, the two jaws remain in a naturally open state, and the distance between the two jaws is greater than the width of the relay. The maintenance personnel insert two fingers into the handles respectively, control the pliers arm to extend into the distribution box, and the two jaws are respectively located on both sides of the relay, and the two fingers are put together, and the jaws are inserted into the gap between the relay and the bottom plate of the distribution box, and the fingers are upward to easily pull up the relay. When the elastic stretching member is in a tightening role, the two jaws are in a closed state, and the maintenance personnel insert two fingers into the handles respectively and open them, and the jaws are stretched open, and the pliers arm is controlled to extend into the distribution box, and the two jaws are respectively located on both sides of the relay, and the two fingers are put together, and the two jaws are automatically closed and inserted into the gap between the relay and the bottom plate of the distribution box, and the fingers are upward to easily pull up the relay.

[0017] Furthermore, the elastic stretching member includes a compression spring, and two side walls of the handle corresponding to the compression spring are respectively provided with embedded blind holes, and two ends of the compression spring are respectively fixed in the two embedded blind holes.

[0018] When the elastic stretching member is a compression spring, two side walls of the handle corresponding to the compression spring are respectively provided with embedded blind holes, and two ends of the compression spring are respectively fixed in the two embedded blind holes.

[0019] Furthermore, the elastic stretching member also includes two fixing pins, each fixing pin is fixed to the corresponding embedded blind hole, the two ends of the compression spring are respectively sleeved and fixed on the corresponding fixing pins, and the sum of the lengths of the two positioning pins is less than the length of the compression spring.

[0020] When the elastic stretching member includes a compression spring, it may also include two fixing pins, each fixing pin is fixed in a corresponding embedded blind hole, and the two ends of the compression spring are respectively sleeved and fixed on the corresponding fixing pins. The fixing pin mainly supports the compression spring to prevent the compression spring from being squeezed and deformed by the handle during the disassembly of the relay due to insufficient strength, making it impossible to complete the disassembly of the relay. In order to allow the compression spring to have an elastic workload, the sum of the lengths of the two positioning pins needs to be less than the length of the compression spring.

[0021] Furthermore, the elastic stretching member is a torsion spring, and two ends of the torsion spring are respectively fixedly connected to the inner side walls of the two handles.

[0022] The elastic stretching member can be a torsion spring or a torsion spring, and the two ends of the torsion spring are respectively fixedly connected to the inner side walls of the two handles.

[0023] In addition, the inner circle of the handle is designed to be a smooth arc shape to improve the comfort of use. The connection between the jaws and the clamp arms is set to a rounded corner to prevent scratching adjacent relays.
