Description

A New Type of Insulated Scissors

technical field

The utility model relates to an insulating scissors for cutting wires.

Background technique

In the work of disconnecting the lead wires under live conditions, after performing insulation shielding or setting insulation isolation measures, the No. 1 electrician uses insulating scissors to cut the lead wires. In order to prevent the lead wires from touching the other two phases and causing a short circuit during the falling process, the No. 2 electrician is required to assist. Insulated locking bar secures lead and lowers slowly. Due to the narrow space in the insulating bucket and the limited parking position of the insulating bucket arm, the two workers may have physical contact, which does not comply with the relevant regulations on live work, causing potential safety hazards, and the No. 2 electrician left the insulating bucket arm The console and the insulated bucket arm are in an unmanned state, and there are also certain potential safety hazards.

Utility model content

The technical problem to be solved by the utility model is to realize an insulating scissors that can simultaneously clamp and cut cables.

In order to achieve the above purpose, the technical solution adopted by the utility model is: a new type of insulating scissors, including a scissors bar and a scissors head; a cable clamp is provided on the side of the scissors head at one end of the scissors bar A push-type control handle is provided, the lower jaw of the cable clamp is fixed on the end of the hollow pipe sleeve, the upper jaw is fixed on the end of the connecting rod, and the connecting rod passes through the pipe sleeve and passes through the The pull wire is connected with the push-type control handle, and the connecting rod between the upper jaw and the lower jaw is provided with a return spring.

The scissors bar and the push-type operating handle are insulating parts.

The upper jaw is a single rod-shaped structure, and the lower jaw is composed of two split rods.

The opposing surfaces of the upper jaw and the lower jaw are provided with anti-slip lines.

The outer ends of the upper jaw and the lower jaw gradually bend toward each other.

The utility model has the advantage that the tool can be used to complete the work of disconnecting the live wire by a single person, which optimizes the process of locking the lead wire and breaking the lead wire, which not only saves time, but also ensures safety, and reduces the direct contact of the staff during live work. Or the time of the wire, which greatly guarantees the personal safety and the safety of the power grid.

Description of drawings

The following is a brief description of the content expressed in each piece of drawings in the specification sheet of the utility model and the marks in the figure:

Fig. 1 is the schematic diagram of the structure of the insulating scissors used at present;

Fig. 2 is a structural schematic diagram of one of the scissor bars of the utility model insulating scissors;

The marks in the above figures are: 1, scissors bar; 2, scissors head; 3, upper jaw; 4, lower jaw; 5, return spring; 6, push-type control handle.

Detailed ways

Referring to Fig. 1, it can be seen that the original insulated scissors are composed of a scissors bar 1 and a scissors head 2. Referring to Fig. 2, it can be seen that the insulated scissors of the present invention is to add a clamping mechanism on one of the scissors bars 1, and the clamping mechanism includes a push-type control handle 6. Pull wires and cable clamps, push-type control handle 6 and scissors bar 1 are preferably made of insulating materials, which have the effect of insulation protection.

The side of the scissors head 2 at one end of the scissors bar 1 is fixed with a cable clamp, and the other end of the scissors bar 1 is provided with a push-type control handle 6, and the pull wire passes through the hollow scissors bar 1 to connect the push-type control handle 6 and the cable clamp, and the push-type control The handle 6 is a device that can be tightened to tighten the pull wire; the cable clamp includes a return spring 5, a sleeve, a connecting rod, an upper jaw 3 and a lower jaw 4, and the sleeve is a hollow tube, one end of which is fixed on the scissors The end of the rod 1 and the other end are vertically fixed with the lower jaw 4, the upper jaw 3 is fixed at the end of the connecting rod, and both are vertical, the connecting rod passes through the sleeve and is connected with the push-type control handle 6 through a pull wire, and returns The spring 5 is installed outside the connecting rod between the upper jaw 3 and the lower jaw 4, so that the push-type control handle 6 is held tightly, and the pull wire is tightened, the upper jaw 3 and the lower jaw 4 move toward each other, and the clamping wire cable, if the push-type control handle 6 is released, the return spring 5 returns to release the cable.

In order to improve the reliability of use, the upper jaw 3 and the lower jaw 4 are provided with anti-slip lines on the opposite sides to increase the clamping stability, and the outer ends of the upper jaw 3 and the lower jaw 4 are gradually bent towards each other, which can avoid the lateral direction of the cable. In addition, the upper jaw 3 is a single rod-shaped structure, and the lower jaw 4 is composed of two split rods, so that the outer ends of the upper jaw 3 and the lower jaw 4 are gradually bent towards each other after being clamped. interference occurs.

The present invention has been exemplarily described above in conjunction with the accompanying drawings. Obviously, the specific implementation of the present invention is not limited by the above-mentioned manner, as long as various insubstantial improvements are carried out by adopting the method concept and technical solutions of the present invention, or without Improvements that directly apply the concept and technical solutions of the present invention to other occasions are within the protection scope of the present utility model.
