In the figure: 1. an insulating operating rod; 2. a pawl; 3. a cylindrical rod; 4. a helical compression spring; 5. a fixed head; 6. a movable head; 7. a linear ratchet; 8. a ground wire connecting screw; 9. a base body.
Detailed Description
The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without any creative effort belong to the protection scope of the present invention. In the following description, for the sake of clarity of illustrating the structure and operation of the present invention, reference will be made to the accompanying drawings by means of directional terms, but the terms "front", "rear", "left", "right", "up", "down", etc. should be construed as convenient terms and not as limitative terms.
The self-locking grounding wire clamp convenient to assemble and disassemble as shown in fig. 1-3 comprises a fixed head provided with a grounding wire connecting screw, a movable head matched with the fixed head, an insulating operating rod, a spiral pressure spring, a base body provided with a pawl therein and a through hole in the middle, and a cylindrical rod with a linear ratchet; the pawl of the seat body points to the through hole; the seat body is fixedly arranged on the fixed head and is opposite to the opening of the fixed head; the cylindrical rod penetrates through the through hole in the seat body and can rotate relative to the through hole; one end of the cylindrical rod is fixedly connected with the movable head, and the other end of the cylindrical rod is fixedly connected with the end part of the insulating operating rod; the spiral pressure spring is sleeved on the cylindrical rod and is positioned between the base body and the fixing head, and the spiral pressure spring is limited by the base body and the fixing head; the pawl and the linear ratchet on the cylindrical rod form a ratchet mechanism; when the pawl is engaged with the linear ratchet on the cylindrical rod, the cylindrical rod can only move towards the direction far away from the fixed head.
In this embodiment, the cylindrical rod and the fixing head are connected by screws, and obviously, the cylindrical rod and the fixing head can also be connected by rivets, clamping or bonding. The cylindrical rod and the insulating operating rod are connected by screws, obviously, the cylindrical rod and the insulating operating rod can also be connected by rivets, clamping or bonding and the like.
The cylinder pole in this implementation is made with the cylinder stick, and straight line ratchet is directly seted up on its wall, and straight line ratchet is the linearity along the length direction of cylinder pole, ensures that the through-hole on cylinder pole and the pedestal rotates steadily.
The working process is as follows:
when the pawl is not engaged with the linear ratchet on the cylindrical rod, as shown in fig. 2, the insulating operating rod is pulled to open the space between the movable head and the fixed head, the insulating operating rod is operated to rotate the cylindrical rod by 180 degrees, at the moment, the pawl is engaged with the linear ratchet on the cylindrical rod, as shown in fig. 3, the cylindrical rod cannot move towards the direction of the fixed head due to the engagement effect of the pawl and the linear ratchet on the cylindrical rod, and the spring is compressed and limited to be incapable of extending; at the moment, after the fixed head of the wire clamp is hung on the wire, the insulating operating rod is operated again to enable the cylindrical rod to rotate 180 degrees, so that the pawl is disengaged from the linear ratchet on the cylindrical rod, and under the resilience action of the spring, the movable head moves upwards and clamps the wire; the operation steps are opposite when the device is disassembled.
The above description is only a preferred embodiment of the present invention, and should not be taken as limiting the invention, and any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
