Description

Technical Field

[0001] The utility model relates to the technical field of rail transit communication equipment maintenance, in particular to an optical cable stripper. Background Art

[0002] Railway communication channels are the "highways" for the collection and transmission of various railway signals. Electric telecontrol, traction power supply, signal CTC (centralized traffic control system), GSM-R wireless (railway wireless communication system based on the global mobile communication system) and other functions must realize signal transmission and collection through this channel, and optical cables are the main channels for railway communication channels to collect and transmit signals. The layout of optical cables around railways is divided into overhead, direct buried, pipeline and other laying methods. Optical cables are relatively special and fragile, and optical cable breakage occurs from time to time, requiring optical cable maintenance operations, but it is difficult to strip optical cables in a confined space environment, which affects the maintenance efficiency.

[0003] At present, conventional optical cable strippers need to be operated with both hands, and one hand needs to pull the optical cable with force, while the other hand needs to hold the stripper. For example, a Chinese invention patent with publication number CN103454725A discloses an optical cable stripper, comprising a first arm and a second arm, the ends of the first arm and the second arm are hinged together, a groove for accommodating the optical cable is provided on the contact surface between the second arm and the first arm, a blade is provided at a position opposite to the groove, a screw rod connected to the second arm is provided on the first arm, and a nut for adjusting the distance between the first arm and the second arm is provided at the end of the screw rod.

[0004] The maintenance of optical cables may be carried out in a variety of complex situations. Traditional optical cable strippers require two-handed operation, which is inconvenient to operate and has a slow stripping speed. It is not convenient to work in confined spaces or at heights. In addition, during the stripping process, due to factors such as the operator's unskilled skills or uneven force, it is easy to cause optical fiber breakage and uneven cutting, affecting the connection and transmission quality.

[0005] Therefore, it is necessary to study an optical cable stripper to solve the above problems or alleviate the impact of the above problems. Utility Model Content

[0028] The utility model will be further described below in conjunction with the accompanying drawings.

[0029] like Figures 1 to 4 As shown, the optical cable stripper of the utility model may include two mirror-symmetrical shear arms 1, one end of the two shear arms 1 is hinged to each other, the side of the two shear arms 1 facing each other is the inner side, the inner side of the shear arm 1 is provided with a clamping block 2, and the inner side of the clamping block 2 is provided with a cutter 3;

[0030] The two clamping blocks 2 can clamp the optical cable, and the two cutters 3 can break the outer sheath of the optical cable under the action of the clamping force.

[0031] Specifically, the two shear arms 1 have the same structure and are symmetrically arranged. One end of the two shear arms 1 is hinged to each other, and the two can rotate relative to the hinged end, so that the ends away from the hinge can be closed to clamp the optical cable to be stripped between the two. A clamping block 2 is provided on the inner side of the two shear arms 1, and a tool 3 is provided on the inner side of the clamping block 2. When the two shear arms 1 are closed, the two clamping blocks 2 can clamp the optical cable for circumferential fixation, and at the same time, the two tools 3 can break the outer sheath of the optical cable under the action of the clamping force. In this way, as the optical cable stripper moves along the length direction of the optical cable, the two tools 3 can easily strip the outer sheath of the optical cable, so as to speed up the stripping speed and improve work efficiency. It is also easy to operate with one hand and convenient for working in confined spaces.

[0032] Furthermore, the hinged ends of the two shear arms 1 are each provided with a connecting hole, and the two connecting holes are connected by a connecting bolt 12 .

[0033] In one example, an adjusting member 4 is provided between the clamping block 2 and the shearing arm 1, and the adjusting member 4 can adjust the position of the clamping block 2 inside the shearing arm 1. Thus, when the two shearing arms 1 are in a closed state, the distance between the two clamping blocks 2 can be adjusted by the adjusting member 4 to be suitable for clamping optical cables of different sizes.

[0034] In an example, Figures 1 to 3 As shown, the adjusting member 4 is an adjusting bolt, the shear arm 1 is provided with a mounting hole 5 which runs through the inner and outer sides thereof, and the adjusting member 4 is passed through the mounting hole 5; one end of the adjusting member 4 located on the inner side of the shear arm 1 is connected to the clamping block 2, and the other end of the adjusting member 4 located on the outer side of the shear arm 1 is a rotating adjusting head.

[0035] Specifically, the adjusting member 4 is an adjusting bolt, and the position of the clamping block 2 can be adjusted by adjusting the adjusting bolt axially. The shear arm 1 is provided with a mounting hole 5 that runs through the inside and outside thereof, and the mounting hole 5 is provided with an internal thread that matches the external thread of the adjusting bolt. The adjusting bolt is passed through the mounting hole 5, and the end of the adjusting bolt located on the inside of the shear arm 1 is connected to the clamping block 2, and the end of the adjusting bolt located on the outside of the shear arm 1 is a rotating adjusting head. In this way, the rotating adjusting head is rotated by an external tool, so that the adjusting bolt is telescopically adjusted in the mounting hole 5 along the axial direction, and then the clamping block 2 connected to the adjusting bolt is adjusted in position along the axial direction of the adjusting bolt on the inside of the shear arm 1. It should be noted that the two mounting holes 5 are symmetrical and have the same axis, and the two adjusting members 4 can be adjusted synchronously to achieve the distance between the two clamping blocks 2.

[0036] Further, the rotation adjustment head can be a hexagonal head, a square head or a disc head. Of course, the rotation adjustment head can also be a head structure that is rotationally matched with a flat (cross) screwdriver.

[0037] In an example, Figures 1 to 3As shown, the clamping block 2 has a center block 6, which is fixed and passes through the clamping block 2. The center block 6 protrudes toward the inside of the clamping block 2 and is used to install the tool 3. The side of the center block 6 facing the shear arm 1 is connected to the adjustment member 4.

[0038] Specifically, the center block 6 is a part in the middle of the clamping block 2, and the side of the center block 6 facing the shear arm 1 is connected to the adjusting member 4, so that the adjusting member 4 can adjust the position of the clamping block 2 and the center block 6 as a whole. The center block 6 protrudes toward the inner side of the clamping block 2 for installing the cutter 3, so that the cutter 3 can break the outer sheath of the optical cable under the action of the clamping force.

[0039] In an example, Figure 3 As shown, a groove 7 is provided on one side of the central block 6 facing the shear arm 1 , one end of the adjusting member 4 extends into the groove 7 and the two are connected to each other via an elastic member 8 .

[0040] Specifically, a groove 7 is provided on one side of the center block 6 facing the shear arm 1, and the end of the adjusting member 4 connected to the clamping block 2 extends into the groove 7 and can move in the groove 7. An elastic member 8 is provided in the groove 7, one end of the elastic member 8 is connected to the end surface of the adjusting member 4, and the other end thereof is connected to the bottom of the groove 7.

[0041] The adjusting member 4 is an adjusting bolt. When the adjusting member 4 is adjusted along its axial direction, the elastic member 8 is deformed to squeeze the center block 6 and the clamping block 2 together to press against the optical cable, so that the clamping block 2 has sufficient pressure to clamp the optical cable, and the tool 3 has sufficient pressure to break the outer sheath of the optical cable. At the same time, the contact between the two and the optical cable is flexible to avoid hard contact so that the tool 3 may damage the internal optical fiber when stripping the outer sheath, thereby ensuring that the force for stripping the optical cable is uniform and improving the cutting quality of the stripped optical cable.

[0042] Furthermore, the elastic member 8 may be a spring.

[0043] In one example, the cutter 3 is conical, and the tips of the two cutters 3 face the same side. In this way, when the blade of the cutter 3 breaks the outer sheath of the optical cable under the action of the clamping force and moves along the length direction of the optical cable, the tip of the cutter can easily break the outer sheath of the optical cable along the length direction of the optical cable, which can reduce the force required for stripping the optical cable, reduce labor intensity, speed up the stripping speed, and do not need to pull the optical cable laboriously, so that one-handed operation can be adopted, which is convenient for confined space operations. Further, the cutter 3 can be triangular cone-shaped.

[0044] In an example, Figure 4As shown, a stopper 9 is provided on one side of the cutter 3 away from the cutter tip, and the width of the stopper 9 is greater than the width of the cutter 3. Thus, after the cutter 3 strips the outer sheath of the optical cable along its length direction, the stopper 9 can further open the stripping opening of the outer sheath to separate the two parts of the outer sheath and expose the required optical fiber, so as to prevent the outer sheath from recovering to form a closed shape and wrapping the optical fiber.

[0045] In one example, the inner sides of the shearing arm 1 and the clamping block 2 are both concave structures to form an escape space for clamping the optical cable. In this way, when the two shearing arms 1 rotate relative to the hinged end to form a closed state, there is a space between the two to accommodate the installation of the clamping block 2, the tool 3 and the clamped optical cable.

[0046] In one example, the shear arm 1 is in a semi-circular structure, and the clamping block 2 is in an arc structure. Thus, when the two shear arms 1 are closed, a circular escape space can be formed. The arc of the clamping block 2 is less than 180°, and is in a C shape.

[0047] In one example, a handle 10 is provided at one end of the shear arm 1 away from the hinge, and an anti-slip rubber sleeve 11 is provided on the handle 10 .

[0048] Specifically, one of the handles 10 on the two shear arms 1 has several concave structures matching the fingers, so that the two handles 10 cooperate with each other to conform to the ergonomic design, facilitate one-handed operation, and provide a comfortable hand feel. The anti-slip rubber sleeve 11 can increase the hand-held friction force to prevent slipping, facilitate hand-held operation, and also improve the comfortable hand feel.

[0049] In order to better understand the above embodiments, the working process of the optical cable stripper of the present invention is further described below in conjunction with the accompanying drawings.

[0050] When using the optical cable stripper, the operator only needs to place the optical cable to be stripped between the two shear arms 1 and between the two clamping blocks 2, align the tool 3 with the edge of the optical cable, and deform the elastic member 8 by adjusting the adjustment member 4. The clamping block 2 clamps the edge of the optical cable, and the tool 3 generates pressure on the outer sheath of the optical cable under the clamping action of the clamping block 2. The operator holds the handle 10 to move the optical cable stripper along the length direction of the optical cable. The tools 3 on both sides can easily strip the outer sheath of the optical cable along the length direction of the optical cable, and the stripped outer sheath can be separated by the positioning block 9 to prevent the outer sheath from recovering, thereby speeding up the stripping speed and improving work efficiency.

[0051] Although the present invention has been described with reference to preferred embodiments, various modifications may be made thereto and parts thereof may be replaced with equivalents without departing from the scope of the present invention. In particular, the various technical features mentioned in the various embodiments may be combined in any manner as long as there is no structural conflict.
