Description

A cutter for cutting the inner diameter of a cable sealing ring

technical field

The utility model belongs to the field of electromechanical technology, in particular to a cutter for cutting the inner diameter of a cable sealing ring.

Background technique

The inner diameter of the sealing ring used for cables in flameproof electrical equipment shall not exceed 1mm of the outer diameter of the cable, and damaged sealing rings shall not be used. There shall be no other binding materials between the sealing ring and the cable. Not only is it laborious and time-consuming, but the processing quality cannot be guaranteed, and it is easy to hurt hands during operation.

Utility model content

The purpose of the utility model is to provide a cutting knife for the inner diameter of the cable sealing ring, which solves the problem of time-consuming and labor-intensive cutting of the hole of the cable sealing ring in the prior art and easily hurts hands.

The technical solution adopted in the utility model is that the cutting knife for the inner diameter of the cable sealing ring includes a 90-degree curved knife tip, the knife tip includes a knife tip and a knife back, and the knife tip gradually becomes thinner and narrower from the knife back to the knife tip. The back of the knife is movably connected in the fixed pipe, and a pair of threaded holes are arranged on the fixed pipe, and the back of the knife inside the fixed pipe and the fixed pipe are fixed by bolts.

The utility model is also characterized in that,

On the side wall with threaded holes opposite to one end of the fixed pipe near the tip of the knife, a height-adjustable support column is vertically movably connected.

An end of the fixed pipe away from the tip of the knife is also connected with a handle.

The height-adjustable support column and the fixed pipe are connected by nuts.

The beneficial effect of the utility model is that the cutting knife for the inner diameter of the cable sealing ring can cut cable sealing rings of different diameters through the gradual thinning and narrowing of the tip of the knife, and the back of the knife and the fixed pipe are movably connected, so that the tip of the knife can be adjusted conveniently stretching length.

Fig. 1 is a structural schematic diagram of the inner diameter cutter of the cable sealing ring of the present invention.

In the figure, 1. Knife tip, 2. Threaded hole, 3. Handle, 4. Nut, 5. Height-adjustable support column, 6. Knife tip, 7. Bolt, 8. Fixed tube, 9. Knife back.

Detailed ways

The utility model will be described in detail below in conjunction with the accompanying drawings and specific embodiments.

The utility model is a cutting knife for the inner diameter of a cable sealing ring, as shown in Figure 1, including a 90-degree curved knife tip 1, the knife tip 1 includes a knife tip 6 and a knife back 9, and the knife tip 1 is from the knife back 9 to the knife The tip 6 gradually becomes thinner and narrower, the back of the knife 9 is flexibly connected in the fixed tube 8, and a pair of threaded holes 2 are opened on the fixed tube 8, and the back of the knife 9 inside the fixed tube 8 and the fixed tube 8 are fixed by bolts 7, and the fixed tube 8 On the sidewall that is oppositely provided with the threaded hole 2 near the end of the knife tip 6, a height-adjustable support column 5 is vertically movably connected, and the height-adjustable support column 5 and the fixed pipe 8 are connected by a nut 4, and the fixed pipe 8 is far away from the knife. One end of the tip 6 is also connected with a handle 3 .

The utility model is an inner diameter cutting knife for cable sealing rings. When in use, first loosen the bolt 7 in the threaded hole 2, and then extend the knife tip 6 into the appropriate cable seal by adjusting the distance that the back of the knife 9 extends into the fixed pipe 8. Then tighten the bolt 7, and then adjust the nut 4 to support the height-adjustable support column 5 in a suitable position, so that the position of the inner diameter cutter of the entire cable sealing ring is adjusted properly, and then hold the handle 3 horizontally Turn clockwise or counterclockwise to make the cable sealing ring successfully, and finally pour out the excess residue.

The inner diameter cutting knife of the cable sealing ring of the utility model can cut different direct cable sealing rings due to the special structure of the knife tip. Moreover, since the knife tip 1 bends from the back of the knife at 9 to 90 degrees, the knife tip 6 gradually becomes thinner and narrower. , so that it can be widely used to cut any diameter of the cable sealing ring, because the knife tip 1 is bent at 90 degrees, which increases the overall stability a lot, and makes the inner diameter cutting knife of the entire cable sealing ring easier to use Convenient, save time and effort.
