Description

Auxiliary nut thread detector

technical field

The utility model relates to an auxiliary nut thread detector.

Background technique

In recent years, with the continuous development of the national economy, the society has higher and higher requirements for the quality of power supply. Improving the reliability of power supply is an important task; It is necessary to vigorously carry out the live work of the distribution network to reduce the power outage inspection and maintenance work of the power distribution network as much as possible. During the operation of the 10 kV distribution network, the operators need to wear insulating gloves to carry out the work according to the regulations. 10 kV live working gloves are generally thicker due to the need for safety protection, and in order to prevent being scratched by sharp objects during operation, a layer of sheepskin gloves is generally added on top. This can play a very good role in assisting the protection of the workers, but at this time when the workers are wearing these thick gloves, the hand feeling is not so sensitive, especially when holding small-sized nuts and confirming the thread. , The existence of the nut is often not felt, and the nut often slips from the hand, which increases the time spent on the operation and consumes the physical strength of the operator, causing the operator to stay in the live area for a long time, and the safety risk is greater.

When wearing thick insulating gloves to carry out operations, it is inconvenient to recognize the status quo of thread buckles, improve the work efficiency of operators, save time and effort, and have good economic benefits.

The auxiliary nut thread detector is safe and firm, easy to rotate, not easy to be damaged, simple in structure, easy to maintain, and saves time and effort. It can reduce the time of workers staying in the live area and reduce the operation risk of live work. It has good performance. Safety benefits.

The ratchet mechanism of the auxiliary nut thread recognition device is equipped with a hand-held collar on the outside, the axis of the hand-held collar is on a straight line with the rotation axis of the ratchet mechanism, and at least one thread communicating with the inner hole is provided on the side wall of the hand-held collar The threaded holes are in one-to-one correspondence with the ratchet mechanism, at least one limit bolt is matched with the corresponding threaded hole and one end of the limit bolt extends into the inner hole of the hand-held collar and leans against the side wall of the ratchet mechanism superior.

After adopting such a structure, the hand-held collar is added to increase the area of the hand surface acting on the auxiliary nut thread detector, making the operation of the auxiliary nut thread detector more convenient and labor-saving.

In addition, the combination of the threaded hole and the limit bolt can increase the solidity of the ratchet mechanism in the hand-held collar, and will not shake back and forth.

The outer wall of the hand-held collar of the auxiliary nut thread detector is provided with a friction surface; after adopting such a structure, the frictional force against the hand-held collar of the operator is increased, and it is not easy to slip.

The number of ratchet mechanisms of the auxiliary nut thread detector is two, and the two ratchet mechanisms are respectively set in the hand-held collar. The connecting ejector rods extend out of the upper and lower end surfaces of the hand-held collar respectively.

After adopting such a structure, the connecting ejector rod of the lower ratchet mechanism can cooperate with the nut casing, and the operator can directly hold the hand-held collar to install and disassemble the nut. If the bolt and the nut are too tightly matched, The connecting ejector rod of the upper side ratchet mechanism can be used to cooperate with the wrench to increase the power arm acting on the nut, increase the acting torque, and complete the installation and disassembly operations.

The ratchet mechanism of the auxiliary nut thread detector is an internal meshing ratchet mechanism; after adopting such a structure, the space occupied by the ratchet mechanism can be reduced, and it is convenient and reasonable to place it.

A limit protrusion is arranged on the side wall of the auxiliary nut thread detector connected to the ejector rod.

detailed description

As shown in Figures 1 to 3

This auxiliary nut thread recognizer comprises a nut sleeve 4 and two ratchet mechanisms.

The two ratchet mechanisms are the first ratchet mechanism 1 on the upper side and the second ratchet mechanism 2 on the lower side. Taking the first ratchet mechanism 1 as an example: the first ratchet mechanism 1 is an internal meshing ratchet mechanism, and the first ratchet mechanism 1 A connecting push rod 11 is fixed on the output shaft, and a limit protrusion 12 is provided on the side wall of the connecting push rod 11. The structure of the first ratchet mechanism 1 and the second ratchet mechanism 2 is the same, and the second ratchet mechanism 2 will not be described here. .

The outside of the first ratchet mechanism 1 and the second ratchet mechanism 2 is equipped with a hand-held collar 3, the rotation axis of the first ratchet mechanism 1 and the second ratchet mechanism 2 is on a straight line with the axis of the hand-held collar 3, and the first ratchet mechanism 1 The connecting push rod 11 of the second ratchet mechanism 2 protrudes out of the upper and lower end faces of the hand-held collar 3 respectively;

There are two threaded holes communicating with the inner hole on the side wall of the hand-held collar 3, and the two threaded holes are distributed on the side wall of the hand-held collar 3 one by one. The two threaded holes correspond to the two ratchet mechanisms one by one. The hole cooperates with the stop bolt 5, and one end of the stop bolt 5 extends into the inner hole of the hand-held collar 3 and leans against the side wall of the corresponding ratchet mechanism, and the outer wall of the hand-held collar 3 is provided with an uneven friction surface 31.
