Description

TECHNICAL FIELD

[0001] The application belongs to the technical field of communication engineering, and particularly relates to a positioning device for communication engineering construction wiring. BACKGROUND

[0002] In large building areas such as high-rise buildings or office buildings, communication cables are often concentrated for wiring, and the communication cables are orderly wired in cooperation with the suspended cable bridge to ensure the communication needs of the users of the whole building. In the communication wiring engineering, the corresponding positioning device is an essential important component.

[0003] Traditional wiring positioning is mostly fixed by using an integral tray or a simple cable tie, and lacks a precise limiting structure for layering and root separation. The cables are easily entangled and stacked in the bridge due to vibration and construction pulling, which not only makes it difficult to quickly identify the line during later maintenance, but also lacks a special clamping groove type fixing design. When a single cable fails, the whole fixed structure needs to be disassembled for replacement, which is complicated to operate and may affect other normal cables. Moreover, the traditional positioning device is mostly a rigid straight structure, which cannot adapt to the curved wiring scenes such as the turning and corner of the cable bridge. The cable is often in a state of no fixation at the turning, and only relies on the natural limiting of the inner wall of the bridge, which may lead to line deviation due to uneven stress, and may cause local extrusion and deformation after long-term use. At the same time, the traditional positioning device is mostly designed in an integrated manner, which is not convenient for fixing and installing when encountering the "cross" intersection or "T" intersection of the cable bridge, and cannot improve the structural stability of the intersection of the cable bridge. Moreover, during later maintenance, if the cable needs to be increased or decreased or the faulty line needs to be replaced, the fixing bolts of the whole positioning device need to be removed, and even the normal operation of the adjacent line needs to be interrupted, which is low in operation efficiency and affects the stability of communication.

[0047] As Figures 5-9 and Figures 16-17As shown, the U-shaped bracket 1 of the embodiment is provided with a bending positioning mechanism 4 matched with the mobile positioning mechanism 3 at one end close to the mobile positioning mechanism 3. The bending positioning mechanism 4 comprises three groups of strip-shaped plates 401, and the same end of the three groups of strip-shaped plates 401 is hinged to one side of the one end of the U-shaped bracket 1. The hinged shafts of the three groups of strip-shaped plates 401 and the U-shaped bracket 1 and the axis of the hinged shaft of the rotating base 301 and the U-shaped bracket 1 coincide. The top of each strip-shaped plate 401 is uniformly provided with a row of third lower clamping grooves 402 for clamping communication cables. The two adjacent groups of strip-shaped plates 401 are connected through a connecting piece 403. The two groups of strip-shaped plates 401 at the head and tail are respectively connected to the rotating base 301 and the U-shaped bracket 1 through the connecting piece 403. The connecting piece 403 is composed of two groups of connecting rods 4031 hinged to each other. The two ends of the connecting piece 403 are respectively hinged to the two adjacent groups of strip-shaped plates 401. The two groups of strip-shaped plates 401 at the head and tail are respectively hinged to the rotating base 301 and the U-shaped bracket 1 through the connecting piece 403. The two sides of the strip-shaped plate 401 are symmetrically provided with a first strip-shaped groove 404 away from the bottom of the end of the hinged shaft of the strip-shaped plate 401 and the U-shaped bracket 1. The side close to the strip-shaped plate 401 of the rotating base 301 and the U-shaped bracket 1 is provided with a second strip-shaped groove 405. The first strip-shaped groove 404 and the second strip-shaped groove 405 are both used for accommodating the connecting rod 4031. The maximum included angle between the two adjacent groups of strip-shaped plates 401 is 30°. The maximum included angle between the two groups of strip-shaped plates 401 at the head and tail and the rotating base 301 and the U-shaped bracket 1 is 30°. The three groups of strip-shaped plates 401 are hinged to the U-shaped bracket 1 and are linked to the rotating base 301 through the connecting piece 403 composed of two groups of connecting rods 4031. When the rotating base 301 rotates, the connecting piece 403 drives the strip-shaped plate 401 to expand synchronously. The maximum included angle between the adjacent strip-shaped plates 401 and between the strip-shaped plate 401 and the rotating base 301 / U-shaped bracket 1 is 30°, forming a continuous supporting surface conforming to the turning radius. The cable clamped into the third lower clamping groove 402 of the strip-shaped plate 401 adapts to the turning direction with the strip-shaped plate angle. In a straight line scene, the connecting rod 4031 is accommodated in the first strip-shaped groove 404 and the second strip-shaped groove 405, keeping the structure compact. The 30° included angle design makes the device cover a wider turning angle of 60°, 90°, 120°, etc. (the total expansion angle is 30° x 4 = 120°), adapting to various bridge turning requirements, especially suitable for obtuse angle turning scenes. The strip-shaped plate 401 expands synchronously with the rotating base 301. The third lower clamping groove 402 always conforms to the cable direction, realizing "contour fixing", reducing cable bending stress and reducing the risk of bending damage. The connecting rod 4031 can be accommodated in the strip-shaped groove, not occupying extra space in a straight line scene, ensuring the compactness of the device structure.

[0048] As Figures 1-9 and Figures 18-19As shown, the two sides of the U-shaped bracket 1 in the embodiment are fixedly connected with the inner wall of the cable bridge through the first fixing structure 5, and the outer side of the moving positioning mechanism 3 is fixedly connected with the inner bottom of the cable bridge through the second fixing structure 6. The first fixing structure 5 includes a second jack 501 arranged on the two sides of the U-shaped bracket 1, and a first fixing bolt 502 is arranged in the second jack 501. The U-shaped bracket 1 is fixedly connected with the inner wall of the cable bridge through the second jack 501 and the first fixing bolt 502. The second fixing structure 6 includes a first fixing seat 601 arranged on one end of the rotating base 301. A second fixing bolt 602 is arranged on the first fixing seat 601. The rotating base 301 is fixedly connected with the inner bottom of the cable bridge through the first fixing seat 601 and the second fixing bolt 602. The second jack 501 arranged on the two sides of the U-shaped bracket 1 penetrates the first fixing bolt 502 to fix the U-shaped bracket 1 with the inner wall of the cable bridge, thereby forming a horizontal stable support. The first fixing seat 601 arranged on one side of the rotating base 301 and the second fixing bolt 602 fix the rotating base 301 with the inner bottom of the cable bridge. In a straight line scene, the first fixing structure 5 forms a double fixing of “inner wall + bottom”. In a turning scene, the rotating base 301 is fixed at the position after turning. The two groups of independent fixing structures fix the device from different directions (inner wall and bottom), so that the device can be stably installed in a straight line section or at a turning position, and displacement of the device caused by cable tension or vibration is avoided. In a turning scene, the double fixing enhances the connection strength between the straight line bridge and the intersection, improves the anti-deformation ability of the overall structure, and ensures the long-term reliability of cable positioning.

[0049] As shown in Figures 1-7 and Figures 10-11 As shown, the top of the fixed positioning mechanism 2 and the moving positioning mechanism 3 in the embodiment is provided with a connecting mechanism 7. The connecting mechanism 7 includes a second fixing seat 701 arranged on one end of the first cover plate 201 close to the rotating base 301. Two groups of third fixing screws 702 are arranged through the top of the second fixing seat 701. Two groups of third screw holes 703 matched with the third fixing screws 702 are arranged on one side of the top of the second cover plate 302. The first cover plate 201 is fixedly connected with the second cover plate 302 through the second fixing seat 701, the third fixing screws 702 and the third screw holes 703. The second fixing seat 701 arranged on the first cover plate 201 is used to screw the third fixing screws 702 into the third screw holes 703 of the second cover plate 302, so that the first cover plate 201 and the second cover plate 302 are connected into a whole, and synchronous opening and closing are realized. In a straight line scene, the cover plate linkage design simplifies the operation. When the number of cables is increased or decreased in the later period, it is not necessary to separately disassemble the two groups of cover plates. It is only necessary to unscrew the third fixing screws 702 to synchronously open, thereby improving the maintenance convenience. After the cover plates are connected into a whole, the stability during closing is stronger, and cable fixing failure caused by loosening of a single group of cover plates is avoided, thereby further ensuring the cable positioning effect.

[0050] The working principle of this embodiment is as follows: First fixing bolts 502 are inserted through the second insertion holes 501 on both sides of the U-shaped frame 1, directly fixing the U-shaped frame 1 to the inner wall of the cable tray. If used in a straight cable tray (i.e., the communication cable does not bend or turn), the rotating base 301 is not unfolded; instead, the first fixing seat 601 on one side of the rotating base 301 is directly fixed to the inner bottom of the cable tray (as shown in the instruction manual) via the second fixing bolts 602. Figure 18 As shown in the diagram, the first cover plate 201 and the second cover plate 302 are fixedly connected by tightening the third fixing screw 702. When placing the communication cable, the first cover plate 201 and the second cover plate 302 are opened simultaneously. Then, the communication cable is sequentially inserted into the first lower slot 203, the third lower slot 402, and the second lower slot 304. Next, the first cover plate 201 and the second cover plate 302 are closed, and the positions of the first cover plate 201 and the second cover plate 302 are fixed by the first fixing screw 205 and the second fixing screw 305, respectively. If the communication cable needs to be bent or turned (as shown in the instruction manual), the following steps can be taken: Figure 19 As shown), after placing the positioning device inside the first set of cable trays, the inner sides of the U-shaped frame 1 are then fixedly connected to the inner walls of the first set of cable trays via the second insertion hole 501 and the first fixing bolt 502. The rotating base 301 is then rotated and unfolded, moving it into the second set of cable trays (forming a "T" shape with the first set of cable trays). The rotating base 301 is then fixedly connected to the inner bottom of the second set of cable trays via the second fixing bolt 602 and the first fixing seat 601. During this process, the rotating base 301 pulls the three sets of strip plates 401 through the connector 403, rotating and unfolding them around the hinge axis between the rotating base 301 and the U-shaped frame 1. Then... Open the first cover plate 201 and the second cover plate 302, and sequentially insert the communication cable into the first lower slot 203, the third lower slot 402 and the second lower slot 304, so that the communication cable bends from the first set of cable trays into the second set of cable trays. Then, put the two sets of first cover plates 201 and second cover plates 302 back on, and let the first fixing screw 205 pass through the first insertion hole 204 and screw it into the first screw hole 206 to fix the two sets of first cover plates 201 to the inner bottom of the U-shaped frame 1. Then, screw the second fixing screw 305 on the second cover plate 302 into the second screw hole 306 on the rotating base 301 to fix the second cover plate 302 to the top of the rotating base 301.

[0051] The above description is merely a preferred embodiment of the present invention and is not intended to limit the scope of protection of the present invention.
