Description

A portable cable cutting device Technical Field

[0001] This utility model relates to the field of cable cutting technology, specifically a portable cable cutting device. Background Technology

[0002] A cable is an insulated conductor assembly used to transmit electrical energy or signals, typically composed of a conductor (copper or aluminum), insulation layer, shielding layer, and sheath. Its core function is to efficiently and safely transmit electricity or data, and it is widely used in power systems, communication networks, transportation facilities, and industrial equipment. Based on application, cables can be classified into power cables (such as high-voltage transmission cables), communication cables (such as fiber optic cables), and special cables (such as fire-resistant and waterproof types). Modern cable design balances conductivity, durability, and safety, making it a core infrastructure for energy transmission and information interconnection. During cable installation, personnel sometimes need to cut the cable using cable cutting devices.

[0003] For example, according to authorization announcement number CN221552663U, a portable cable cutting device includes a frame with a cavity inside. A cutting blade is slidably mounted in the cavity. Symmetrically distributed grooves are provided on the frame, and U-shaped sliders are slidably connected in two of the grooves. The cutting blade is placed between the two U-shaped sliders. A U-shaped connecting block is provided on the top of the cutting blade. Two hexagonal bolts are threaded onto both the U-shaped sliders and the U-shaped connecting block, with the threads of the hexagonal bolts penetrating the cutting blade. An L-shaped block is fixedly connected to the front of the U-shaped connecting block, and a connecting rod is fixedly connected to the L-shaped block. A stop block is fixedly connected to the other end of the connecting rod. A spring sleeved on the outside of the connecting rod is fixedly connected between the L-shaped block and the stop block. An insert rod is fixedly connected to the back of the stop block, and a round block is fixedly connected to the top of the U-shaped connecting block. This application allows for easy removal and replacement of the cutting blade, and allows the support rod and the first handle to be removed, making the device easy to carry and improving its convenience.

[0004] The aforementioned technology uses a person pressing down on the handle to drive the cutting blade to cut the cable. However, when the cable diameter is large, it is difficult to effectively cut the cable by simply pressing down. Therefore, there is an urgent need in the market to develop a portable cable cutting device to help people solve the existing problems. Summary of the Invention

[0005] The purpose of this utility model is to provide a portable cable cutting device to solve the problem mentioned in the background art that the existing technology uses personnel to press down on the handle to drive the cutting blade to cut the cable, but when the cable diameter is large, it is difficult to effectively cut the cable by simply pressing down.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a portable cable cutting device, comprising a supporting base plate, a supporting seat fixedly connected to the upper middle part of the supporting base plate, a semi-circular placement groove provided in the upper middle part of the supporting seat, a C-shaped support frame connected to the upper end of the supporting seat, a cutting blade connected to the upper inner side of the C-shaped support frame, a pressure plate fixedly connected to the upper middle part of the cutting blade, a manual hydraulic rod fixedly connected to the upper middle part of the C-shaped support frame, the lower end of the telescopic end of the manual hydraulic rod passing through the upper middle part of the C-shaped support frame and extending to the upper end of the pressure plate and fixedly connected to a circular pressure plate.

[0007] Preferably, rectangular slots are provided on both sides of the upper surface of the support base, and the lower sides of the C-shaped support frame are respectively inserted into the two rectangular slots. The lower end of the C-shaped support frame and the support base are fixed together by two L-shaped pins.

[0008] Preferably, a T-shaped limiting groove is provided on both sides of the inner end face of the C-shaped support frame, and a guide rod is fixedly connected to the middle of the two T-shaped limiting grooves.

[0009] Preferably, a T-shaped slider is fixedly connected to the upper ends of both sides of the cutting blade, and a guide hole is provided in the middle of the T-shaped slider.

[0010] Preferably, the T-shaped sliders on both sides of the cutting blade slide into the two T-shaped limiting grooves respectively.

[0011] Preferably, the two guide rods pass through the guide holes of the two T-shaped sliders respectively.

[0012] Preferably, a flange is fixedly connected to the lower end of the manual hydraulic rod, and the flange is fixedly connected to the upper end face of the C-shaped support frame by multiple bolts.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] (1) In this utility model, the design of manually driven hydraulic rod to drive the cutting knife is adopted. The cutting force is significantly improved by the hydraulic force amplification principle, which can easily cut large-diameter cables and solve the problem of insufficient force of traditional pressure cutting device.

[0015] (2) In this utility model, a dual guiding mechanism of T-shaped limiting groove and guide rod is set to ensure that the cutting blade maintains stable linear motion during the pressing process, avoids cutting deviation, and improves cutting accuracy and safety.

[0016] (3) In this utility model, the support base and the C-shaped support frame can be separated. When the cable is long and the cutting position is in the middle, the two L-shaped pins are pulled out to separate the C-shaped support frame from the upper end of the support base. The cable cutting position can be placed directly on the semi-circular placement groove. Then the C-shaped support frame and the support base can be fixed again by the two L-shaped pins 203 for cutting. The operation is convenient. Attached Figure Description

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0023] Please refer to Figures 1-4. One embodiment of this utility model provides a portable cable cutting device, including a support base plate 1. A support seat 2 is fixedly connected to the upper middle part of the support base plate 1. A semi-circular placement groove 201 is provided in the upper middle part of the support seat 2. A C-shaped support frame 3 is connected to the upper end of the support seat 2. A cutting blade 4 is connected to the upper inner side of the C-shaped support frame 3. A pressure plate 401 is fixedly connected to the upper middle part of the cutting blade 4. A manual hydraulic rod 5 is fixedly connected to the upper middle part of the C-shaped support frame 3. The lower end of the telescopic end of the manual hydraulic rod 5 passes through the upper middle part of the C-shaped support frame 3 and extends to the upper end of the pressure plate 401, where a circular pressure plate 503 is fixedly connected. The cable is passed through the inside of the C-shaped support frame 3, and the position where the cable needs to be cut is placed on the semi-circular placement groove 201. By operating the manual hydraulic rod 5, the telescopic end of the manual hydraulic rod 5 drives the circular pressure plate 503 to descend and press down on the pressure plate 401, causing the pressure plate 401 to drive the cutting blade 4 to descend and cut the cable.

[0024] Please refer to Figure 2. T-shaped limiting grooves 301 are provided on both sides of the C-shaped support frame 3. Guide rods 302 are fixedly connected to the center of each of the two T-shaped limiting grooves 301. T-shaped sliders 402 are fixedly connected to the upper ends of both sides of the cutting blade 4. Guide holes 403 are provided in the center of each T-shaped slider 402. The T-shaped sliders 402 on both sides of the cutting blade 4 slide into the two T-shaped limiting grooves 301 respectively. The two guide rods 302 pass through the guide holes 403 of the two T-shaped sliders 402 respectively. When the cutting blade 4 descends to cut the cable, the T-shaped sliders 402 slide along the T-shaped limiting grooves 301, and the guide holes 403 slide along the guide rods 302, providing dual guidance to ensure the stability of the cutting blade 4's descent and prevent deviation during descent.

[0025] Please refer to Figure 3. Rectangular slots 202 are provided on both sides of the upper surface of the support base 2. The lower sides of the C-shaped support frame 3 are inserted into the two rectangular slots 202 respectively. The lower end of the C-shaped support frame 3 and the support base 2 are fixed by two L-shaped pins 203. When the cable is long and the cutting position is in the middle, the C-shaped support frame 3 can be pulled out from the upper end of the support base 2 by pulling out the two L-shaped pins 203. The cable cutting position can then be placed directly on the semi-circular placement groove 201. The C-shaped support frame 3 and the support base 2 can then be fixed again by the two L-shaped pins 203 for cutting. The operation is convenient.

[0026] Please refer to Figures 2 and 4. The lower end of the manual hydraulic rod 5 is fixedly connected to a flange 501. The flange 501 is fixedly connected to the upper end face of the C-shaped support frame 3 by multiple bolts 502. By removing the multiple bolts 502, the manual hydraulic rod 5 can be separated from the C-shaped support frame 3 for easy disassembly and carrying.

[0027] Working Principle: During use, the cable to be cut is passed through the C-shaped support frame 3, and the cable is adjusted so that the cutting position is aligned with the semi-circular placement groove 201 of the support base 2. When the cable is long, the L-shaped pin 203 can be pulled out to separate the C-shaped support frame 3 from the support base 2, and the cable can be placed directly before reassembly. The operator turns the handle of the manual hydraulic lever 5, which hydraulically drives the circular pressure plate 503 to press down on the pressure plate 401, causing the cutting blade 4 to move steadily downwards along the T-shaped limiting groove 301 and the guide rod 302. The double guiding mechanism ensures that the cutting process does not deviate. Under the hydraulic amplification, the cutting blade 4 gradually cuts into the cable, and the mechanical advantage generated by the hydraulic transmission can easily cut large-diameter cables.

[0028] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.
