Description

Technical Field

[0001] The utility model belongs to the technical field of electric power equipment, in particular to a grip ring device for a cable head. Background Art

[0002] In today's power systems, ensuring a secure connection between the current and voltage circuits and the secondary circuits within the circuit breaker mechanism box is crucial. To achieve this, a grip ring is often used to connect the secondary wire connectors. This connection method requires the operator to possess certain professional skills and experience to ensure that the grip ring's size and quality meet standards. However, existing grip ring operation methods primarily rely on needle-nose pliers, which requires a relatively high level of operator experience.

[0003] In practice, operators may encounter problems when using needle-nose pliers to grip the screw. For example, sometimes the grip is too large, preventing the screw from being properly secured in place; while other times, the grip is too small, preventing the screw from being properly inserted, resulting in an insecure connection. These issues not only increase the difficulty of the operation but can also lead to repeated rework, impacting overall work efficiency and system stability. Utility Model Content

[0018] The following is a clear and complete description of the technical solutions in the embodiments of the present invention with reference to the accompanying drawings:

[0019] like Figure 1-5As shown, a grip ring device for a cable head comprises a base plate 1, a bracket 2 and a hand crank 3, wherein the upper surface of the base plate 1 is provided with two brackets 2; the two brackets 2 are welded into a triangular shape, and the triangular brackets play a stable supporting role; a rolling bearing 4 is welded at the intersection of the top ends of the two brackets 2; the hand crank 3 runs through the rolling bearing 4; an interface 9 is provided at one end of the hand crank 4; the outer wall of one end of the hand crank 4 is welded to the inner side wall of the inner ring of the rolling bearing 4, and the outer bottom of the outer ring of the rolling bearing 4 is welded to the bracket, and the inner side of the rolling bearing 4 is driven by the ball on the inner side of the hand crank 4. The rotation of the inner ring can realize the rotation effect, and the interior of the interface 9 at the end where the hand crank 4 extends is hollow, and an external thread is provided on the outside; the interface 9 is correspondingly provided with four strip-shaped notches for clipping screw bits 8 of different diameters, and the notches can be fixed with the tail clips of screw bits 8 of different diameters; one end of the inner side of the nut 5 is provided with an internal thread for use with the external thread of the interface 9, and a screw bit 8 is inserted into the interface 9, which is fixedly connected by the nut 5 and the interface 9. The nut 5 is provided with a wavy groove along the circumference, which effectively prevents slipping when rotating and tightening; the upper end of the nut 5 is provided with a clamping structure.

[0020] Specifically, the clamping structure includes a plywood 6, an anti-slip strip 7, a spring 11 and a round rod 12; one end of the plywood 6 is bent upward to facilitate construction workers to press the internal spring 11 downward to lift the other end upward, and the lower plate surface at the other end of the plywood 6 is in the shape of a trapezoidal groove, forming a trapezoidal space inside, which can be clamped and fixed according to wire cores of different diameters; two ear plates 10 are provided at the corresponding bending position of the lower plate surface at one end of the plywood 6, and both ear plates 10 are in the shape of discs; a groove 13 is provided on the upper part of the nut 5; the round rod 12 passes through the ear plate 10 and the spring 11 in sequence, and the two ends of the round rod 12 are fixed to the inner side of the middle of the groove 13.

[0021] Specifically, an anti-slip strip 7 is provided in the trapezoidal groove at the other end of the clamping plate 6, which better fits the outer wall of the wire core, effectively prevents sliding, and plays a clamping role.

[0022] When in use, the operator first places the entire device on the ground or on a table, selects a screwdriver bit 8 of corresponding diameter according to the diameter of the grip ring required, and inserts it into the interface 9, and fixes the screwdriver bit 8 with the nut 5. After being fixed, one end of the nut 5 is a distance away from one end of the rolling bearing 4, which does not affect the simultaneous rotation of the nut 5 and the screwdriver bit 8. The operator then presses down the raised end of the splint 6, raises the other end of the splint 6, and fixes the wire core that needs to be gripped through the trapezoidal space at the other end of the splint 6. The operator grabs one end of the wire core with one hand and starts to rotate the hand crank handle 4 with the other hand to start rotating the nut 5 to drive the splint 6 and the screwdriver bit 8 to rotate together, completing the gripping work.

[0023] The above merely describes a preferred specific embodiment of the present application, but the protection scope of the present application is not limited thereto, any skilled person in the art, according to the technical scheme and improvement concept of the present application, makes equivalent replacement or change within the technical range disclosed by the present application, which should be covered in the protection scope of the present application.
