The beneficial effect is: since the handle is made of insulating epoxy resin, the wrench can carry out emergency repairs on the equipment with electricity, ensuring the safety of the repair personnel; in addition, the fixed opening of the wrench body is equipped with a self-locking device to lock the nut, washer and spring pad , to prevent the parts from slipping, which greatly facilitates the construction personnel, and at the same time avoids the safety hazard caused by the falling parts.

Description

A self-locking insulating wrench

technical field

The invention relates to a fastening tool; in particular, it relates to an insulating wrench used in the power supply industry.

Background technique

Due to the quality problems of the equipment itself, problems with the installation or improper connection process, poor contact of the connection parts, aging equipment, large load and other problems of the power equipment in the power supply industry, the joints will heat up. Due to load requirements and power outage time constraints, defective equipment cannot be repaired in a timely manner, and live work can only be used to deal with it.

At present, the ratchet wrench used in live work is hand-held, small in size, light in weight, and easy to operate. However, because it is a high-altitude live work worker, it is necessary to wear insulating gloves. Spring pad.

Contents of the invention

The technical problem to be solved by the present invention is to provide an insulating wrench capable of fixing parts on the insulating wrench, having a self-locking function, and capable of live working.

The technical solution adopted in the present invention is: an insulating wrench with self-locking, including a handle and a wrench body; one end of the wrench body is connected to the handle, and the other end of the wrench body is two fixed openings; the one A self-locking device is installed on the fixed opening.

The self-locking device includes a spring and a lock body; a groove is formed on the outer peripheral surface of the fixed opening, and the groove goes from shallow to deep from the lower end of the fixed opening to the upper end, and between the inner side of the lower end of the lock body and the outer side of the fixed opening A spring is fixedly installed between them, and the upper end of the lock body is on the same plane as the fixed opening, and is inclined to the inside of the fixed opening.

A protrusion is formed at the lower end of the lock body.

The material of the lock body is the same as that of the wrench body.

The material of the handle is insulating epoxy resin.

The beneficial effects of the present invention are: since the handle is made of insulating epoxy resin, the wrench can carry out emergency repairs on the equipment with electricity, ensuring the safety of the repair personnel; in addition, the fixed opening of the wrench body is equipped with a self-locking device, and the nut, washer and spring pad It is locked to prevent the parts from slipping, which greatly facilitates the construction personnel, and also avoids the safety hazard caused by the falling of the parts.

detailed description

Below in conjunction with accompanying drawing and specific embodiment the present invention is described in further detail:

As shown in Figures 1 to 4, the present invention has a self-locking insulating wrench, including a handle 10 and a wrench body 20; one end of the wrench body 20 is connected to the handle, and the other end of the wrench body 20 is two fixed openings ; A self-locking device 30 is fixedly installed on the fixed opening. The material of the lock body 31 is the same as that of the wrench body 20; the material of the handle 10 is insulating epoxy resin; the self-locking device 30 includes a spring and the lock body 31; The groove is from the lower end of the fixed opening from shallow to deep to the upper end. The width of the groove is the same as the width of the lock body 31. A spring is fixedly installed between the inner side of the lower end of the lock body 31 and the groove on the outer peripheral surface of the fixed opening. The lock body The upper end of 31 is on the same plane as the fixed opening, and is inclined to the inner side of the fixed opening; the lower end of the lock body 31 is formed with a protrusion 32, which is convenient for pressing the nut by hand to loosen the clamped timely; After the nut, the washer and the spring pad, the spring is extruded and gives a reaction force to the lock body 31, so that the front end of the lock body 31 clamps the placed object, which solves the inconvenience in operation caused by wearing safety protective equipment; in addition, the handle 10 is insulating epoxy resin, and the dielectric strength is 4.5 times the rated voltage, which meets the requirements of the preventive test regulations and meets the professional requirements for live work.

Because the handle is insulated in the present invention, the fastening wrench can carry out emergency repairs on the equipment with electricity, avoiding power outage maintenance, and ensuring the safety of repair personnel; security risks.

It is worth pointing out that the protection scope of the present invention is not limited to the above-mentioned specific examples, and the purpose of the present invention can still be achieved according to the basic technical concept of the present invention; Embodiments all belong to the protection scope of the present invention.
