Description

Technical Field

[0001] The utility model relates to the technical field of hardware tools, in particular to a circlip pliers. Background Art

[0002] During the assembly and adjustment of mechanical parts, some shaft workpieces need to have retaining rings installed in the shaft grooves of machines and equipment to prevent the axial movement of parts on the shaft.

[0003] When commonly used circlip pliers are designed, the arc of the circlip pliers is slightly smaller than the diameter of the circlip in order to be able to clamp the circlip. Circlip pliers are generally divided into two types: removal type and installation type. When operating the installation type circlip pliers, the operator needs to wear protective gloves to put the circlip into the circlip pliers, and then push it hard to push the circlip into the shaft groove of the shaft workpiece; when using the removal type circlip pliers, the circlip opening needs to be rotated towards the circlip pliers, and then the circlip pliers are used to push the circlip out with force.

[0004] Thus, different types of circlip pliers are needed when installing and removing circlips, which makes the circlip pliers relatively single in function, and relatively troublesome in actual operation and inconvenient to use. Utility Model Content

[0030] Please refer to Figures 1 to 3The utility model proposes a circlip pliers 1000 for removing and installing a circlip 2000. The circlip pliers 1000 include a pliers handle 1, a pliers arm 2 and two magnetic blocks 3. The pliers arm 2 is arranged at one end of the pliers handle 1, and a through slot 21 capable of accommodating the circlip 2000 is formed at the end of the pliers arm 2 away from the pliers handle 1. A partition hole 22 extending along the length direction of the pliers arm 2 is formed on the slot wall of the through slot 21. Two limiting portions 23 are formed at the end of the pliers arm 2 away from the pliers handle 1, and the two limiting portions 23 can partially cover the notch of the through slot 21; each of the magnetic blocks 3 is connected to a limiting portion 23 and is located on the same side of the pliers arm 2. Partial structures of the two magnetic blocks 3 can partially cover the through slot 21 and are used to adsorb the circlip 2000.

[0031] In the technical solution of the utility model, when installing the retaining spring 2000, first put the retaining spring 2000 into the through groove 21 from the side facing away from the magnetic block 3. After the retaining spring 2000 is adsorbed and fixed by the magnetic block 3, the side of the clamp arm 2 facing away from the magnetic block 3 is close to the axis groove of the retaining spring 2000, and then the opening direction of the retaining spring 2000 is aligned with the axis groove of the retaining spring of the shaft workpiece. The retaining spring 2000 can be installed in the axis groove of the retaining spring by pushing it forward. After installation, the retaining spring pliers 1000 are pulled out along the axial direction of the shaft workpiece to complete the installation of the retaining spring 2000. When removing the retaining ring 2000, first move the clamp arm 2 of the retaining ring pliers 1000 toward the side facing away from the magnetic block 3 and close to the shaft workpiece, then move the retaining ring pliers 1000 along the axial direction of the shaft workpiece so that the retaining ring 2000 is accommodated in the through groove 21, and the end of the retaining ring 2000 abuts against the two limiting parts 23 and is adsorbed and fixed by the magnetic block 3, then drag the clamp handle 1 in the direction opposite to the opening of the retaining ring 2000, and the retaining ring 2000 can be removed under the dragging of the two limiting parts 23 on the end of the retaining ring 2000. The circlip pliers 1000 provided by the utility model can be used when disassembling or installing the circlip 2000. When the conventional disassembly type circlip pliers 1000 are used to disassemble the circlip 2000, the circlip 2000 is easy to pop out and fall off due to the large rigidity of the circlip 2000. The magnetic block 3 is provided to absorb and fix the circlip 2000, so that the circlip 2000 is not easy to fall off during the disassembly and assembly process, thereby improving the safety of the operation.

[0032] The retaining spring 2000 may be a C-type retaining spring or an E-type retaining spring, and the present invention does not impose any restriction on this. In order to ensure that the retaining spring 2000 can be adsorbed by the magnetic block 3, a magnetic coating may be coated on the surface of the retaining spring 2000, or magnetic material may be added during the production process of the retaining spring 2000, and the present invention does not impose any restriction on this.

[0033] In order to improve the structural stability of the clamp arm 2 and the limiting portion 23, in one embodiment of the utility model, the limiting portion 23 and the clamp arm 2 are an integrally formed structure. The integral forming can eliminate the weakness of the connection between the clamp arm 2 and the limiting portion 23, improve the strength and stability of the overall structure, and reduce the risk of material fatigue and fracture compared to threading, welding or other connection methods; through the integral forming, the number of parts to be manufactured can be reduced, and the design and assembly process can be simplified, which helps to reduce production costs and improve production efficiency.

[0034] In order to improve the structural stability of the magnetic block 3 and the limiting portion 23, in one embodiment of the utility model, the limiting portion 23 and the magnetic block 3 are an integrally formed structure. Integral forming can achieve a more complex design and structure, improve the performance and function of the product, and achieve higher sealing, wear resistance or pressure resistance; integral forming can eliminate the weakness of the connection between the magnetic block 3 and the limiting portion 23, improve the strength and stability of the overall structure, and reduce the risk of material fatigue and fracture compared to threading, welding or other connection methods; integral forming can eliminate gaps or defects at the connection, improve the appearance and surface quality of the product, and the overall component is usually more beautiful and refined.

[0035] In order to better limit the position of the clamping spring 2000 in the through slot 21, in one embodiment of the present invention, refer to Figure 3 , the through groove 21 is an arc groove adapted to the clip 2000. The arc groove adapted to the clip 2000 can ensure that the clip 2000 is correctly installed therein, preventing the clip 2000 from shifting or falling off during use; the arc groove can ensure that the clip 2000 is firmly fixed therein, reducing the risk of accidental falling off, thereby improving the safety of operation; the arc groove can make the clip 2000 easier to install and disassemble, improve assembly efficiency, save time and labor costs, and also make the overall structure more beautiful and improve the product appearance quality.

[0036] In order to improve the working efficiency, safety and comfort of the circlip pliers 1000, in one embodiment of the utility model, the pliers handle 1 is provided with an anti-skid groove extending along the length direction of the pliers handle 1. The anti-skid groove can provide additional friction, increase the stability when holding the pliers handle 1, and prevent the hand from sliding, so that it is easier to control the use of the pliers handle 1, and less effort is required when holding the pliers handle 1, reducing hand fatigue and improving work efficiency. It can also reduce the risk of accidental sliding or loss of control, ensuring that the hand is firmly held when using the circlip pliers 1000, reducing the possibility of accidental injury, and providing an anti-skid groove makes it easier to control the force and direction when holding the pliers handle 1, improves the accuracy of the operation, and avoids inaccurate operation caused by hand sliding.

[0037] Specifically, see Figure 3In one embodiment of the utility model, the partition hole 22 separates part of the structure of the clamp arm 2 into a first clamp arm 24 and a second clamp arm 25 arranged side by side, and the two limiting parts 23 are respectively connected to the first clamp arm 24 and the second clamp arm 25. By separating the clamp arms, a more uniform clamping force can be provided, and the two clamp arms can share the pressure and load of the two limiting parts 23, increase the stability of the clamping spring 2000, and reduce the risk of accidental sliding or movement. In addition, the two clamp arms can open a certain angle during the process of disassembling and installing the clamp spring 2000 to better adapt to the installation and disassembly of the clamp spring 2000, and can also increase the limiting effect on the clamp spring 2000 in one direction, so that the clamp spring 2000 is not easy to fall during the installation and disassembly process.

[0038] See also Figure 3 In one embodiment of the utility model, the clamp arm 2 is provided with a plurality of through holes 26, which are arranged at intervals along the length direction of the clamp arm 2, and the plurality of through holes 26 are all connected to the partition hole 22. On the one hand, the provision of the through holes 26 can save materials, and on the other hand, the provision of the plurality of through holes 26 can make the through slot 21 open freely, so that when the clamp spring 2000 is pushed by the clamp arm 2, the through slot 21 at the front end of the clamp arm 2 opens, and at the same time, the clamp arm 2 forms a counter-clamping force, so that the clamp spring 2000 is firmly locked.

[0039] See also Figure 3 In one embodiment of the utility model, the plurality of through holes 26 are equally spaced, and the central axis of the plurality of through holes 26 is collinearly arranged with the central axis of the partition hole 22. The collinear arrangement design also helps to reduce stress concentration of the clamp arm 2, improve the durability and reliability of the clamp arm 2, and enable the clamp arm 2 to be more evenly stressed.

[0040] In one embodiment of the utility model, the circlip pliers 1000 further include an anti-slip sleeve, which is provided on the end of the pliers handle 1 away from the pliers arm 2. The provision of the anti-slip sleeve can improve the comfort and operational stability of the operator, and reduce the risk of hand fatigue and slippage. The anti-slip sleeve is usually made of soft material, which can provide a good grip and anti-slip effect, and can ensure that the operator can better control the circlip pliers 1000 during use, thereby improving the operational accuracy and efficiency. In addition, the anti-slip sleeve can also protect the surface of the pliers handle 1 and extend the service life of the circlip pliers 1000.

[0041] In one embodiment of the utility model, the clamp arm 2 is located on the central axis of the clamp handle 1. Placing the clamp arm 2 on the central axis of the clamp handle 1 can achieve balanced distribution, which makes the user feel more stable and comfortable when using it, which helps to reduce hand fatigue, especially when used for a long time. The design of the central axis can also make the opening and closing action of the clamp arm 2 more stable and precise, so that the clamping force and clamping position can be controlled more accurately, and the operation accuracy can be improved. Moreover, since the clamp arm 2 is located on the central axis, the force applied to the clamped object will be more evenly distributed, reducing the risk of accidental sliding or loss of control, improving safety, and making it easier for the user to control the opening and closing action of the clamp arm 2, so as to more conveniently clamp the retaining spring 2000 and complete the operation.

[0042] The above description is only a preferred embodiment of the present invention, and does not limit the patent scope of the present invention. All equivalent structural changes made by using the contents of the present invention specification and drawings under the inventive concept of the present invention, or directly / indirectly applied in other related technical fields are included in the patent protection scope of the present invention.
