Description

Technical Field

[0001] This utility model belongs to the field of drone assembly technology, specifically relating to a self-tightening wire tie pliers suitable for confined operating spaces. Background Technology

[0002] Aviation cable connectors are widely used in the field of UAV manufacturing. The reliability of the anti-loosening binding wire treatment of aviation cable connectors during UAV assembly directly affects the assembly quality and electrical system stability of UAVs. In order to improve the reliability and efficiency of anti-loosening binding wire, special binding pliers are usually designed to perform anti-loosening binding wire operation of aviation cable connectors.

[0003] The drawbacks of traditional wire binding tools:

[0004] Traditional methods of securing anti-loosening cable ties in aviation cables use surgical hemostats. Because surgical hemostats have an "X" shaped lever structure, with the hinge axis close to the jaws and far from the handle, significant handle displacement is required to open and close the jaws. Furthermore, the oval-shaped handguard at the handle end further increases the operating space required. Due to the complex internal structure and limited operating space of drones, surgical hemostats cannot perform precise tying operations, failing to meet the assembly requirements of drones. Therefore, a cable tying clamp suitable for confined operating spaces is more advantageous, improving the reliability and efficiency of anti-loosening ties. Utility Model Content

[0032] To make the objectives, contents, and advantages of this utility model clearer, the specific embodiments of this utility model will be described in further detail below with reference to the accompanying drawings and examples.

[0033] This embodiment provides a self-tightening wire pliers suitable for confined operating spaces, including: a fixed clamp body 1, a pin 2, a movable clamp body 3, a steel wire 4, a handle 5, a button 6, a return spring 7, and a pull rod 8;

[0034] The fixed clamp body 1 has a slotted jaw at the front end with a countersunk hole for the pin thread, a rectangular cross-section rod-shaped body in the middle section, and a stepped shaft with external threads and an axial through hole at the end. The front end of the fixed clamp body 1 is connected to the movable clamp body 3 through the pin 2. The external thread of the stepped shaft at the end is connected to the handle 5. The end of the handle 5 is inserted into the button 6. The stepped shaft at the end of the fixed clamp body 1 is provided with a pull rod 8. The end of the pull rod 8 is inserted into the front end of the button 6. A return spring 7 is provided at the connection between the pull rod 8 and the button 6.

[0035] The front end of the movable clamp body 3 is configured as a jaw, the middle section is provided with a pin hole, and the end is configured as a rectangular cross-section sheet with a wire-passing hole. The end of the movable clamp body 3 is connected to the front end of the wire-drawing 4 through the wire-passing hole, and the end of the wire-drawing 4 is fixed to the front end of the pull rod 8.

[0036] The pin 2 has an external thread at one end and a slot at the other end. The pin 2 serves as a rotating shaft between the fixed clamp body 1 and the movable clamp body 3.

[0037] The front end of the steel wire 4 is set as a C-shaped open ring, which is inserted into the wire threading hole through the switch ring. The steel wire 4 is used to connect the movable clamp body 3 and the pull rod 8, and plays the role of pushing and pulling the movable clamp body 3 to rotate around the pin shaft 2.

[0038] The handle 5 is a long tube structure, with an internal threaded hole at the front end and anti-slip knurling and stepped smooth holes on the outer diameter of the end.

[0039] The button 6 is designed as a two-stage stepped shaft structure, with a thin end at the front end and an internal thread.

[0040] The button 6 has a thicker end with a concave spherical anti-slip groove, which is located outside the end of the handle 5.

[0041] The reset spring 7 is a helical compression spring structure, used to push the pull rod 8 and the steel wire 4, thereby driving the movable clamp 3 to close, clamp, and reset.

[0042] The pull rod 8 has a three-section stepped shaft structure. The front end of the pull rod 8 has an axial inner hole as a receiving end of the end of the steel wire 4. The middle section of the pull rod 8 has five equally divided radial countersunk holes. The end of the pull rod 8 has an external thread that is threaded to the button 6 to transmit the force of the reset spring 7 and the button 6 to the steel wire 4.

[0043] The tie rod 8 is fixed to the steel wire 4 by welding in the axial inner hole at the front end.

[0044] By pressing and releasing button 6, the fixed clamp body 1 and the movable clamp body 3 are opened and closed to clamp the tie wire and insert it into the anti-loosening hole of the aviation cable connector. By rotating handle 5, the tie wire is rotated and tightened to complete the anti-loosening tie wire operation.

[0045] The working process of this utility model:

[0046] The working process of this utility model is mainly divided into two processes: threading the binding wire and tightening the binding wire to prevent loosening.

[0047] During the wire threading process, pressing button 6 compresses the return spring 7, simultaneously moving the pull rod 8 and the steel wire 4 towards the movable clamp body. The steel wire 4 pushes the movable clamp body 3 to rotate around the pin 2, opening the jaws. Place the wire into the jaws formed by the fixed clamp body 1 and the movable clamp body 3. Release button 6; under the pressure of the return spring, button 6 moves the pull rod 8 and the steel wire 4 away from the movable clamp body. The steel wire 4 pulls the movable clamp body 3 to rotate around the pin 2, closing the jaws and clamping the wire. By holding the handle 5, thread the wire through the wire-binding holes at both ends of the aviation cable connector. Press button 6 to open the jaws, separating the wire pliers from the wire, completing the threading process.

[0048] To tighten the cable tie to prevent loosening, release button 6 to close the jaws, and simultaneously clamp both ends of the cable tie into the jaws, forming a closed loop. Rotate handle 5 clockwise or counterclockwise, causing the jaws to rotate the two ends of the cable tie together, causing them to spiral and cross, gradually forming a "twisted" shape. The length of the non-crossing section of the cable tie between the two ends of the aviation cable connector gradually decreases. When the two ends of the connector are pulled together, the tightening process to prevent loosening is complete.

[0049] The above description is only a preferred embodiment of the present utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the technical principles of the present utility model, and these improvements and modifications should also be considered within the protection scope of the present utility model.
