DETAILED DESCRIPTION

[0031] The preferred embodiments of the present invention are described in detail below in conjunction with the accompanying drawings so that the advantages and features of the present invention can be more easily understood by those skilled in the art, thereby making a clearer and more definite definition of the protection scope of the present invention.

[0032] like Figure 2-10 The figure shows a railway digital signal cable on-site processing device described in this embodiment, which can be carried to the railway digital signal cable wiring construction to perform wiring operations. The device includes a base 1, a first swing arm 2, a second swing arm 3 and other components. Among them, the base 1 is integrally formed with plastic. A cable insertion channel 11 extending along the first direction is processed on the base 1. The cable insertion channel 11 is arranged through the base 1. The inner diameter of the cable insertion channel 11 is adapted to the outer diameter of the cable, and the cable can be inserted into the cable insertion channel 11. In this embodiment, the first direction is defined as the thickness direction of the base 1. In specific use, the base 1 has a rotation state rotating around the central axis of the cable insertion channel 11 and a moving state moving along the first direction. In the specific structural design, the base 1 has a first hinge position 14 and a second hinge position 15 arranged relatively spaced in the second direction. The second direction is defined as the length direction of the base 1. The cable insertion channel 11 is arranged between the first hinge position 14 and the second hinge position 15. A plurality of cable insertion channels 11 are arranged at intervals between the first hinge position 14 and the second hinge position 15. Each cable insertion channel 11 has a different inner diameter. The cable insertion channels 11 with different inner diameters are arranged to meet the insertion requirements of cables with different outer diameters.

[0033] The aforementioned first swing arm 2 has a designed length, and its first end is hinged to the first hinge position 14 by the cooperation of the pin shaft and the pin hole, and its second end extends in the direction close to the second hinge position 15. The first swing arm 2 is hinged on the base 1, and it rotates around the first hinge position 14 to have a first cutting position and a first disengagement position. A first cutter 4 is installed on the first swing arm 2 corresponding to each cable insertion channel 11. In the first cutting position and the aforementioned rotation state, the first cutter 4 has a first cutting end extending into the cable insertion channel 11, and a cutting track having the first cutting end moving in the circumferential direction. When the cable is inserted into the cable insertion channel 11, the first cutting end of the first cutter 4 contacts the outer skin of the cable, and by rotating the base 1, the first cutting end moves along the cutting track, so that the outer skin 9 of the cable can be cut off in the circumferential direction. In this embodiment, the first cutter 4 is a sheet-like blade structure, which is fixedly mounted on the first swing arm 2 by screws. The cutting end of the first cutter 4 is a conventional blade structure, and the above-mentioned cutting effect is achieved by reasonably arranging the direction of the blade of the first cutter 4. In this embodiment, the direction of the blade edge of the blade is arranged perpendicular to the first direction. When in the aforementioned first disengaged position, the first swing arm 2 drives the first cutter 4 away from the cable insertion channel 11, so that the first cutter 4 moves out of the cable insertion channel 11.

[0034] In this embodiment, a relief groove 13 is processed on the base body 1, and the relief groove 13 is connected with the cable insertion channel 11. The first swing arm 2 drives the first cutter 4 to enter and exit the cable insertion channel 11 through the relief groove 13.

[0035] The aforementioned second swing arm 3 has a designed length, and its first end is hinged to the second hinge position 15 by the cooperation of the pin shaft and the pin hole, and its second end extends in the direction close to the first hinge position 14. The second swing arm 3 is hinged on the base 1, and it rotates around the second hinge position 15 to have a second cutting position and a second disengagement position. A second cutter is installed on the second swing arm 3 corresponding to each cable insertion channel 11. In the second cutting position and the aforementioned moving state, the second cutter has a second cutting end extending into the cable insertion channel 11, and a cutting track with the second cutting end moving along the first direction. When the cable is inserted into the cable insertion channel 11, the second cutting end of the second cutter contacts the outer skin of the cable, and by pushing the base 1 or pulling the cable, the base 1 moves relative to the cable in the first direction, and then the second cutting end moves along the aforementioned cutting track, so that the cable outer skin 9 can be cut along the length direction of the cable. In this embodiment, the second cutter is a sheet-like blade structure, which is fixedly mounted on the second swing arm 3 by screws. The second cutting end of the second cutter is a triangular structure, having a tip and a cutting edge located on one side or both sides of the tip. The above-mentioned cutting effect is achieved by reasonably arranging the direction of the cutting edge of the second cutter. In this embodiment, the cutting edge is arranged toward one side in the first direction. When in the aforementioned second disengaged position, the second swing arm 3 drives the second cutter away from the cable insertion channel 11, so that the second cutter moves out of the cable insertion channel 11.

[0036] In this embodiment, a first spring is installed between the first swing arm 2 and the base 1. The first spring is a coil spring, and the first spring has an elastic force that drives the first swing arm 2 to move from the first cutting position to the first disengaged position. When the first swing arm 2 is located at the first cutting position, the elastic force of the first spring acts to automatically reset the first swing arm 2 to the first disengaged position. Among them, a first limiting assembly is installed between the first swing arm 2 and the second swing arm 3. The first limiting assembly includes two first stop blocks 5. The two first stop blocks 5 are respectively installed on the first swing arm 2 and the second swing arm 3. In the aforementioned first cutting position, the two first stop blocks 5 stop and cooperate with each other in the moving direction of the second swing arm 3 to limit the second swing arm 3 from moving from the second disengaged position to the second cutting position. Specifically, as Figure 4 As shown, the aforementioned first stop block 5 is installed on the end of the first swing arm 2 away from the first hinge position 14, and the aforementioned first stop block 5 is installed on the second swing arm 3 at a position close to the second hinge position 15. When the first swing arm 2 is located at the first cutting position and the second swing arm 3 is located at the second disengaged position, the first stop block 5 on the first swing arm 2 blocks the movement of the first stop block 5 on the second swing arm 3, thereby limiting the movement of the second swing arm 3 toward the second cutting position.

[0037] In this embodiment, a second spring 71 is installed between the second swing arm 3 and the base 1. The second spring 71 is a coil spring, and the second spring 71 has an elastic force that drives the second swing arm 3 to move from the first cutting position to the first disengaged position. When the second swing arm 3 is located at the second cutting position, the elastic force of the second spring 71 acts to automatically reset the second swing arm 3 to the second disengaged position. Among them, a second limiting assembly is installed between the first swing arm 2 and the second swing arm 3. The second limiting assembly includes two second stop blocks 6. The two second stop blocks 6 are respectively installed on the first swing arm 2 and the second swing arm 3. In the aforementioned second cutting position, the two second stop blocks 6 stop and cooperate with each other to limit the first swing arm 2 from moving from the first disengaged position to the first cutting position. Specifically, as Figure 6 As shown, the aforementioned second stop block 6 is installed on the end of the second swing arm 3 away from the second hinge position 15, and the aforementioned second stop block 6 is installed on the first swing arm 2 at a position close to the first hinge position 14. When the second swing arm 3 is located at the second cutting position and the first swing arm 2 is located at the first disengaged position, the second stop block 6 on the second swing arm 3 blocks the movement of the second stop block 6 on the first swing arm 2, thereby limiting the movement of the first swing arm 2 toward the first cutting position.

[0038] In the above structural design, the first hinge position 14 of the first swing arm 2 and the second hinge position 15 of the second swing arm 3 are arranged on opposite sides of the base 1 to distinguish the moving directions of the first swing arm 2 and the second swing arm 3, so that the overall operation process is clear and orderly, and the convenience of the operation is effectively improved. The free end of the first swing arm 2 (the end away from the first hinge position 14) corresponds to the second hinge position 15 of the second swing arm 3, and the free end of the second swing arm 3 (the end away from the second hinge position 15) corresponds to the first hinge position 14 of the first swing arm 2, so as to facilitate the position arrangement of the first limit assembly and the second limit assembly, and realize the corresponding stop function.

[0039] The cable insertion channel 11 on the base 1 is composed of two parts. The cable insertion channel 11 corresponding to the second swing arm 3 is an integrated structure. The cable insertion channel 11 corresponding to the first swing arm 2 is a split structure. Specifically, a plurality of semicircular structures are processed on the base 1. A plurality of semicircular structures are processed on the first swing arm 2. When the first swing arm 2 is located at the second cutting position, the semicircular structure on the base 1 and the semicircular structure at the corresponding position on the first swing arm 2 are combined to form a complete cable insertion channel 11.

[0040] In this embodiment, a hand grip 7 is installed at one end of the first swing arm 2 away from the first hinge position 14 and at one end of the second swing arm 3 away from the second hinge position 15. Correspondingly, a hand grip matching portion 812 is formed on the base 1 corresponding to the hand grip 7. Through the above structural design, by simultaneously holding the hand grip 7 and the hand grip matching portion 812, the first swing arm 2 can be switched to the first cutting position, and the second swing arm 3 can be switched to the second cutting position.

[0041] When in use, the digital signal cable is inserted into the corresponding cable insertion channel 11. Grip the hand grip 7 and the hand grip matching portion 812 on one side to switch the first swing arm 2 to the first cutting position, and rotate the base 1 at the same time to drive the first cutting end of the first cutter 4 to move in the circumferential direction, so that the outer skin of the cable can be cut in the circumferential direction. After releasing the first swing arm 2, grip the hand grip 7 and the hand grip matching portion 812 on the other side to switch the second swing arm 3 to the second cutting position, push the base 1 or pull the cable so that the base 1 and the cable move relative to each other, so as to drive the second cutting end of the second cutter to move in the length direction of the cable, so that the outer skin of the cable can be cut, and the cut outer skin is torn toward the root (i.e., the aforementioned position of cutting in the circumferential direction), and then the entire outer skin is peeled off. By combining the above methods, the outer skin of the cable can be stripped, and the outer skin end face 91 of the stripped cable is flat and consistent, retaining the integrity of the cable outer skin 9, and the overall volume is small, the weight is light, and it is easy to carry, effectively meeting the on-site construction requirements of digital signal cables. During the cutting operation, the first limit assembly and the second limit assembly are stopped and limited, which can prevent the first swing arm 2 and the second swing arm 3 from being in the cutting position at the same time, preventing interference with the operation process, and the operation process is safe, reliable, and highly practical.

[0042] The above description is only an embodiment of the present invention, and does not limit the patent scope of the present invention. Any equivalent structure or equivalent process transformation made using the contents of the present invention specification, or directly or indirectly applied in other related technical fields, are also included in the patent protection scope of the present invention.
