Description

Technical Field

[0001] This utility model relates to the field of electrical engineering technology, and in particular to an adjustable mineral cable rapid stripping device. Background Technology

[0002] With the continuous development of the construction and installation industry, mineral cables have been widely used in various projects. During the installation process, according to the construction specifications, the cables in the distribution box (cabinet) need to be kept neat and aesthetically pleasing. Therefore, the cables entering and leaving the distribution box need to be stripped inside the box.

[0003] The traditional method for stripping mineral cables currently used is to cut them with a hand-held knife. Since the outer layer of mineral cables consists of a polyolefin sheath and a metal insulating layer, it is impossible to cut and remove the polyolefin sheath and the metal insulating layer at once, making the stripping process very difficult and inefficient. Utility Model Content

[0004] The purpose of this invention is to provide an adjustable mineral cable rapid stripping device to solve the problems mentioned in the background art.

[0005] An adjustable mineral cable rapid stripping device is characterized by comprising two parallel supporting square steels, namely a movable square steel located above and a fixed square steel located below, which are connected by a connecting rod. A ring-cutting blade and a longitudinal-cutting blade are rotatably connected to the bottom end face of the movable square steel, and two planar pulleys are provided on the top end face of the fixed square steel corresponding to the ring-cutting blade, and a U-shaped pulley is provided corresponding to the longitudinal-cutting blade.

[0006] Preferably, there are two connecting rods, which are fixedly connected to the fixed square steel, and the movable square steel is simultaneously sleeved on the two connecting rods and slidably connected to the connecting rods.

[0007] Preferably, a spring is fitted onto the connecting rod, and the spring is located between the fixed square steel and the movable square steel.

[0008] Preferably, the circumferential cutting blade and the longitudinal cutting blade are perpendicular to each other, and the U-shaped pulley and the flat pulley are arranged parallel to each other.

[0009] Preferably, the planar pulley includes a pulley seat, on which two clamping pulleys are slidably connected, and two steering columns are rotatably connected. A drive motor is fixedly connected to one side of the pulley seat, and a drive roller is provided on the output shaft of the drive motor. The drive roller is connected to the clamping pulleys and steering columns via a transmission belt.

[0010] Preferably, a screw is provided between the fixed square steel and the movable square steel. The bottom end of the screw is rotatably connected to the fixed square steel. The movable square steel is sleeved on the screw, and a nut is fixedly connected to the movable square steel. The nut is threadedly connected to the screw.

[0011] Preferably, a handle is fixedly connected to the upper end of the screw, and a sleeve is fitted onto the handle, with the sleeve rotatably connected to the handle.

[0012] Compared with the prior art, the advantages of this invention are as follows: This device can adjust the distance between the ring-cutting blade and the flat pulley through the adjustment of the stud and bolt, and can also adjust the distance between the longitudinal cutting blade and the U-shaped pulley. This allows the device to process mineral cables of different diameters. The ring-cutting blade and the flat pulley cooperate to fix the cable between them. By manually rotating the cable or controlling the drive motor to rotate the cable between the two flat gears, the ring-cutting blade can rotate and cut off the circumference of the cable, thus creating a ring-shaped cut in the cable. The cable should be placed on a U-shaped pulley, allowing the pulley and the slitting blade to press and fix the cable. Simultaneously, by adjusting the handle, the slitting blade continues to press down, piercing the cable's outer sheath. Then, the cable is pulled out along the U-shaped pulley, while the slitting blade rolls along the cable's axis, cutting a slit in the cable's axial direction. This allows for easy peeling of the cable sheath, exposing the internal conductor. The entire process is simple, easily cutting and removing the cable's end sheath to prepare the connection end. It is convenient, quick, and efficient, with an adjustable cutting diameter and wide applicability. Attached Figure Description

[0016] The following will describe specific embodiments and appendices. Figure 1-2 The technical solutions in the embodiments of this utility model will be clearly and completely described.

[0017] An adjustable mineral cable rapid stripping device includes two parallel supporting square steels, which are plate materials. The two supporting square steels are a movable square steel at the top and a fixed square steel 1 at the bottom. Two connecting rods 3 are fixedly connected to the top surface of the fixed square steel 1. The connecting rods 3 are arranged in a direction perpendicular to the top surface of the fixed square steel 1. A movable square steel 2 has through holes corresponding to the two connecting rods 3. The movable square steel 2 is connected to the two connecting rods 3 through the through holes and can slide freely relative to the connecting rods 3. A spring 31 is sleeved on the connecting rod 3. The spring 31 is located between the movable square steel 2 and the fixed square steel 1. It can provide elastic force when the gap between the movable square steel 2 and the fixed square steel 1 decreases, so that the movable square steel 2 can bear the force away from the fixed square steel 1.

[0018] A circumferential cutting blade 6 and a longitudinal cutting blade 8 are rotatably connected to the bottom end face of the movable square steel. The circumferential cutting blade 6 and the longitudinal cutting blade 8 have the same basic structure, both including a blade base. A circular circumferential cutting blade 6 or longitudinal cutting blade 8 is rotatably connected to the blade base. The circumferential cutting blade 6 and the longitudinal cutting blade 8 can rotate freely relative to the blade base. Two flat pulleys 5 and one U-shaped pulley 7 are provided on the top end face of the fixed square steel 1. The two flat pulleys 5 are corresponding to the circumferential cutting blade 6, and the U-shaped pulley 7 is corresponding to the longitudinal cutting blade 8. The flat pulleys 5 are located directly below the circumferential cutting blade 6, and the U-shaped pulley 7 is located directly below the longitudinal cutting blade 8. Both the flat pulleys 5 and the U-shaped pulley 7 are rotatably connected to the fixed square steel 1.

[0019] The planar pulley 5 includes a pulley seat 51, on which two clamping pulleys 52 are slidably connected. The two clamping pulleys 52 are arranged side by side and have the same diameter. The distance between the two clamping pulleys 52 is greater than the sum of their radii, resulting in a small gap. However, this gap is not large enough to allow a cable to pass through. Two steering columns 53 are also rotatably connected to the pulley seat 51. One steering column 53 is located in the lower middle part of the pulley seat 51, and the other is located on the lower side of one side of the pulley seat 51. A drive motor 54 is also provided on one side of the pulley seat 51. 4. A drive roller is fixedly connected to the output shaft of the drive motor 54 and fixedly connected to the movable square steel 2. The drive roller is connected to two clamping pulleys 52 and two steering columns 53 through the transmission belt 55, so that the drive motor 54 can drive the two clamping pulleys 52 to rotate through the transmission belt 55. Therefore, when the cable is placed between the two clamping pulleys 52 and the movable square steel 2 is pressed down, the circumferential cutting blade 6 can contact and cut the outer sheath of the cable along the radial direction of the cable. The drive motor 54 can drive the two clamping pulleys 52 to drive the cable to rotate, so that the circumferential cutting blade 6 can cut the outer sheath of the cable along the circumference.

[0020] The circumferential cutting blade 6 and the longitudinal cutting blade 8 are arranged perpendicularly to each other, and the circumferential cutting blade 6 is arranged parallel to the U-shaped pulley 7. The U-shaped pulley 7 and the flat pulley 5 are also perpendicular to each other, so that the cable can be inserted from the same side of the device for operation. The U-shaped pulley 7 has a U-shaped groove, which can limit the cable and keep the cable at the bottom of the U-shaped groove. This allows the longitudinal cutting blade 8 above it to cut into the cable sheath along the cable axis and then pull it outward. While the cable moves in a straight line, the longitudinal cutting blade 8 will cut a mark along the radial direction of the cable. With the combined action of the circumferential cutting blade 6 and the longitudinal cutting blade 8, the outer sheath of the cable end can be cut and easily removed.

[0021] A screw 4 is provided between the fixed square steel 1 and the movable square steel 2. The bottom end of the screw 4 is rotatably connected to the fixed square steel 1, and a nut 41 is fixedly connected to the movable square steel 2. The screw 4 passes through the movable square steel 2 and is threadedly connected to the nut 41, so that the rotation of the screw 4 can adjust the distance between the movable square steel 2 and the fixed square steel 1. This allows the device to clamp and fix cables of different sizes, and thus perform stripping operations on cables of different sizes. A handle 42 is fixedly connected to the top end of the screw 4, making it easier to rotate the screw 4. A sleeve 43 is fitted onto the handle 42 and is rotatably connected to the handle 42. The sleeve 43 can rotate freely relative to the handle 42, making it easier for the operator to hold the sleeve 43 and rotate the handle 42.

[0022] Except for the technical features described in the specification, all other technologies are known to those skilled in the art.

[0023] In this utility model, "upper", "lower", "left", "right", "front" and "back" are relative positions used to facilitate the description of positional relationships, and therefore cannot be understood as absolute positions as a limitation on the scope of protection.

[0024] The above description is merely an example and illustration of the structure of this utility model. Those skilled in the art can make various modifications or additions to the specific embodiments described or use similar methods to replace them, as long as they do not deviate from the structure of the utility model or exceed the scope defined in the claims, they should all fall within the protection scope of this utility model.
