Description

Technical Field

[0001] The utility model relates to the technical field of cable docking, in particular to a simple secondary cable alignment device. Background Technique

[0002] A cable is a wire made of one or more mutually insulated conductors and an outer insulating protective layer, which is laid underground, in the air, etc. A cable generally consists of three parts: a conductor, an insulating layer, and a protective layer. During the erection process, sometimes two cables need to be docked and combined, so a special docking device is required.

[0003] Therefore, a prior art rapid docking device for cables, with the publication number: CN216252136U. When in use, press two groups of connecting rods, then insert one end of the two groups of connecting rods into the connection slots at the same time, and then complete the docking between the first docking device and the second docking device. The trapezoidal blocks on the surface of the connecting rod automatically snap into the internal card slots. Secondly, the first spring presses against the first connecting block by its elastic force, pushing one end of the connecting rod towards the outside of the first docking device. The hinge block is affected by the torsion spring and pushes the other end of the connecting rod towards the outside, so that the connecting rod can be fixed. When releasing the docking, manually push the pushing module, so that the second connecting block drives the moving sliding rod to move, and then the moving sliding rod pushes the trapezoidal module into the internal card slot to push out the trapezoidal block on the surface of the connecting rod inserted into the card slot, and then open the first docking device and the second docking device to complete the release of the docking.

[0004] However, because the cable is exposed in the air for a long time, and the card slots and connection slots are located on the surfaces of the first connector and the second connector, the torsion spring and the first spring will also be exposed in the air and are easily corroded by rainwater in the air and then rust, which will affect the smoothness of elastic expansion and contraction, and thus will affect the smoothness of subsequent disassembly. Content of the Utility Model

[0005] The purpose of the utility model is to solve the problems existing in the prior art, and to propose a simple secondary cable alignment device.

[0006] To achieve the above purpose, the utility model adopts the following technical scheme: a simple secondary cable alignment device, including a left sleeve and a right sleeve for sleeving on two sections of cables. One ends of the outer walls of the left sleeve and the right sleeve are both fixedly connected with two fixing rings. A plurality of clamping blocks distributed in a circular array and used for biting the surface of the cable are inserted between the two fixing rings. A plurality of mounting seats distributed in a circular array and with the same quantity are installed at the other ends of the outer walls of the left sleeve and the right sleeve. One side of the mounting seat on the left sleeve is rotatably connected with a clamping strip, and the mounting seat on the right sleeve is fixedly connected with an inserting strip for inserting into the clamping strip, and the mounting seat on the right sleeve is inserted into the mounting seat on the left sleeve.

[0007] Preferably, a number of notches are formed on the surface of one of the fixing rings, and a clamping block is engaged at the position of the notch between the two fixing rings. A number of triangular cross-section protrusions are integrally formed on the inner arc surface of the clamping block, and one side of the clamping block is hinged to the side of the clamping block.

[0008] Preferably, the clamping block is inserted into the notch, and a bolt threaded to the two fixing rings is penetrated through the clamping block.

[0009] Preferably, the outer arc surface of the clamping block is concave-convex, and the depressions on the outer arc surfaces of a number of clamping blocks are connected and fixed by a clamp.

[0010] Preferably, the end face of the mounting seat on the left sleeve is hollowed out, and a convex strip inserted into the hollowed-out portion of the end face of the mounting seat on the left sleeve is fixedly connected to the end face of the mounting seat on the right sleeve.

[0011] Preferably, a slot is formed on the side of the inserting strip away from the right sleeve. The clamping strip is U-shaped and inserted into the slot, and a limiting strip for abutting against the clamping strip is inserted into the slot wall of the slot. A pin shaft is penetrated through the limiting strip.

[0012] Preferably, a pushing block for fixing the clamping strip is inserted into the other end face of the mounting seat on the left sleeve. A number of circular rings are fixedly connected to the end faces of the pushing blocks. Bolts are also threaded on the circular rings, and the bolts on the pushing blocks are used to abut against the side surface of the fixing ring.

[0013] Compared with the prior art, the advantages and positive effects of the present utility model are as follows.

[0014] 1. In the present utility model, the left sleeve and the right sleeve are fixed on the cable. The relative positions of the right sleeve and the left sleeve are initially aligned. During the initial alignment process, by relatively moving the left sleeve and the right sleeve until the inserting strip fits on the surface of the mounting seat on the left sleeve, and pushing the clamping strip to rotate and insert into the inserting strip, the secondary docking of the cable can be achieved. The components in this solution are all rigid components and will not deform when exposed to the air for a long time, thus ensuring the smoothness of installation or disassembly.

[0015] 2. In the present utility model, after the left sleeve and the right sleeve are sleeved on the cable, the clamp is clamped at the depression on the outer arc surface of the clamping block, and the clamp is tightened, so that a number of clamping blocks can move closer to the cable direction. The protrusions on the clamping blocks are embedded into the surface of the cable to fix the relative position between the clamping blocks and the cable, and further fix the relative position between the left sleeve or the right sleeve and the cable.

[0021] In order to more clearly understand the above-mentioned objects, features and advantages of the present utility model, the following further describes the present utility model with reference to the drawings and embodiments. It should be noted that, without conflict, the embodiments of the present application and the features in the embodiments can be combined with each other.

[0022] In the following description, many specific details are set forth in order to fully understand the present utility model. However, the present utility model can also be implemented in other ways different from those described herein. Therefore, the present utility model is not limited by the specific embodiments disclosed in the following specification.

[0023] As Figures 1-4 shown, a simple secondary cable alignment device includes a left sleeve 1 and a right sleeve 2 for sleeving on two sections of cables. At one end of the outer walls of the left sleeve 1 and the right sleeve 2, two fixed rings 5 are fixedly connected respectively. Between the two fixed rings 5, a plurality of clamping blocks 4 distributed in an annular array and used for biting the surface of the cable are inserted. At the other end of the outer walls of the left sleeve 1 and the right sleeve 2, a plurality of mounting seats 3 distributed in an annular array and with the same quantity are installed. On one side of the mounting seat 3 on the left sleeve 1, a clamping bar 8 is rotatably connected. On the mounting seat 3 on the right sleeve 2, an insert bar 7 for inserting into the clamping bar 8 is fixedly connected. And the mounting seat 3 on the right sleeve 2 is inserted into the mounting seat 3 on the left sleeve 1.

[0024] Specifically, the left sleeve 1 and the right sleeve 2 are respectively sleeved on the end parts of the two sections of cables to be butt-jointed, and then the left sleeve 1 and the right sleeve 2 are fixed on the cables. During butt-jointing, first, the relative position is initially aligned directly by inserting the mounting seat 3 on the right sleeve 2 into the mounting seat 3 on the left sleeve 1. During the initial alignment process, the clamping bar 8 is in an inclined state. When the left sleeve 1 and the right sleeve 2 are butted until the insert bar 7 on the right sleeve 2 fits the surface of the mounting seat 3 on the left sleeve 1, and the clamping bar 8 is pushed to rotate and inserted into the insert bar 7, the secondary butt-joint of the cables can be achieved.

[0025] Moreover, the components in this solution are all rigid members and will not deform when exposed to air for a long time, thus ensuring the smoothness of installation or disassembly.

[0026] In addition, a number of notches 17 are formed on the surface of one of the fixing rings 5, and a clamping block 6 is clamped at the position of the notch 17 between the two fixing rings 5. A number of triangular protrusions 11 are integrally formed on the inner arc surface of the clamping block 4, and one side of the clamping block 4 is hinged to the side of the clamping block 6.

[0027] The clamping block 6 is inserted into the notch 17, and a bolt 10 that is threadedly connected to the two fixing rings 5 is penetrated through the clamping block 6.

[0028] The outer arc surface of the clamping block 4 is arranged in a concave-convex shape, and the depressions on the outer arc surfaces of a number of clamping blocks 4 are fixedly connected by a clamp.

[0029] Specifically, the bolt 10 and the notch 17 in this solution can ensure that the clamping block 6 is fixed between the two fixing rings 5. Since the clamping block 4 is hinged to one side of the clamping block 6, when the left sleeve 1 and the right sleeve 2 are sleeved on the cable, the movable connection of the clamping block 4 can make the clamping block 4 swing, ensuring that the cable will not contact the protrusion 11 and cause interference. After the left sleeve 1 and the right sleeve 2 are sleeved on the cable, the clamp is clamped at the depression on the outer arc surface of the clamping block 4, and the clamp is rotated and tightened, so that a number of clamping blocks 4 can be moved closer to the cable. By embedding the protrusion 11 on the clamping block 4 into the surface of the cable, the relative position between the clamping block 4 and the cable is fixed, and then the relative position between the left sleeve 1 or the right sleeve 2 and the cable is fixed.

[0030] In addition, the end face of the mounting seat 3 on the left sleeve 1 is arranged in a hollow shape, and a convex strip 15 that is inserted into the hollow part of the end face of the mounting seat 3 on the left sleeve 1 is fixedly connected to the end face of the mounting seat 3 on the right sleeve 2.

[0031] Specifically, by first inserting the convex strip 15 into the side of the mounting seat 3 on the left sleeve 1, the relative position between the left sleeve 1 and the right sleeve 2 can be initially fixed.

[0032] In addition, a slot 12 is formed on the side of the insertion bar 7 away from the right sleeve 2. The clamping bar 8 is arranged in a U shape that is inserted into the slot 12, and a limiting bar 13 for resisting the clamping bar 8 is inserted into the slot wall of the slot 12. A pin shaft 14 is penetrated through the limiting bar 13.

[0033] Specifically, when the clamping bar 8 is inserted into the slot 12 in a rotating posture, since the shape of the slot 12 is rectangular, a gap will be reserved between the clamping bar 8 and the slot 12. Therefore, by inserting the limiting bar 13 to fill the gap between the clamping bar 8 and the slot 12, the relative position between the clamping bar 8 and the slot 12 can be fixed, and then the relative position between the left sleeve 1 and the right sleeve 2 can be fixed.

[0034] In addition, on the other end face of the mounting seat 3 on the left sleeve 1, a push block 16 for fixing the clamping strip 8 is inserted. A circular ring 9 is fixedly connected to the end faces of a number of push blocks 16. A bolt 10 is also threadedly connected to the circular ring 9, and the bolt 10 on the push block 16 is used to abut against the side surface of the fixing ring 5.

[0035] Specifically, by rotating the bolt 10 on the circular ring 9, the circular ring 9 drives the push block 16 to approach the clamping strip 8, and pushes one side of the clamping strip 8, causing the clamping strip 8 to rotate. Therefore, it can be ensured that before the left sleeve 1 and the right sleeve 2 are inserted, the clamping strip 8 is in an inclined state, ensuring that the insertion strip 7 slides smoothly on the surface of the mounting seat 3 on the left sleeve 1.

[0036] Working principle: Rotate the bolt 10 on the circular ring 9 to drive the circular ring 9 to drive the push block 16 to push one side of the clamping strip 8, causing the clamping strip 8 to rotate into an inclined state. Slip the left sleeve 1 and the right sleeve 2 respectively onto the two ends of the cables to be docked. Then, use the bolt 10 to install the clamping block 6 again, and use a clamp to clamp the clamping block 4 to the surface of the cable. First, insert the convex strip 15 into the side surface of the mounting seat 3 on the left sleeve 1, and then continuously slide the left sleeve 1 and the right sleeve 2 until the insertion strip 7 on the right sleeve 2 fits the surface of the mounting seat 3 on the left sleeve 1. Pull out the push block 16, and the clamping strip 8 rotates to insert into the insertion strip 7. By inserting the limiting strip 13 to fill the gap between the clamping strip 8 and the slot 12, the relative position of the clamping strip 8 and the slot 12 can be fixed.

[0037] The above is only the preferred embodiment of the present invention, and it is not a limitation of the present invention in other forms. Any person skilled in the art may use the disclosed technical content to make changes or modifications into equivalent embodiments with equivalent changes and apply them to other fields. However, as long as it does not depart from the technical content of the technical solution of the present invention, any simple modification, equivalent change, and modification made to the above embodiments based on the technical essence of the present invention still fall within the protection scope of the technical solution of the present invention.
