Description

Technical Field

[0001] This invention belongs to the field of communication engineering technology, and specifically relates to a positioning device for communication engineering construction and cabling. Background Technology

[0002] In large building areas such as high-rise buildings or office buildings, communication cables are often laid out in a centralized manner. The communication cables are laid out in an orderly manner with the help of suspended cable trays to ensure the communication needs of all users in the building. In communication cabling projects, the corresponding positioning devices are an essential component.

[0003] Traditional cable positioning often uses integrated trays or simple cable ties for fixing, lacking a precise layered and individual cable positioning structure. Cables inside the cable tray are prone to tangling and stacking due to vibration and construction pulling, making it difficult to quickly identify the lines during later maintenance. Without a dedicated slot-type fixing design, replacing a faulty cable requires disassembling the entire fixing structure, which is cumbersome and can affect other normal cables. Furthermore, traditional positioning devices are mostly rigid linear structures, unsuitable for curved cable trays such as bends and corners. Cables are often unfixed at bends, relying solely on the natural restraint of the cable tray wall, which can lead to uneven stress and line deviation, potentially causing localized compression and deformation over time. Additionally, traditional positioning devices are often integrated designs, making them inconvenient to fix at "+" or "T" shaped intersections of cable trays, failing to improve the structural stability of the intersection. Moreover, during later maintenance, adding or removing cables or replacing faulty lines requires removing the fixing bolts of the entire positioning device, potentially interrupting the normal operation of adjacent lines, resulting in low operational efficiency and affecting communication stability. Summary of the Invention

[0004] The technical problem to be solved by the present invention is to overcome the shortcomings of the prior art and provide a positioning device for wiring construction in communication engineering.

[0005] The technical solution adopted to solve the above-mentioned technical problems is: a positioning device for construction and cabling of communication engineering, including a U-shaped frame, a fixed positioning mechanism for fixing communication cables is provided on the top of the U-shaped frame, a movable positioning mechanism for fixing communication cables is symmetrically provided at one end of the U-shaped frame, a bending positioning mechanism that cooperates with the movable positioning mechanism is provided at the end of the U-shaped frame near the movable positioning mechanism, the inner sides of the U-shaped frame are fixedly connected to the inner wall of the cable tray through a first fixing structure, the outer side of the movable positioning mechanism is fixedly connected to the inner bottom of the cable tray through a second fixing structure, and a connecting mechanism is provided on the top of the fixed positioning mechanism and the movable positioning mechanism.

[0006] Furthermore, the fixing and positioning mechanism includes a first screw hole, and two sets of the first screw holes are provided, with the two sets of first screw holes located at the middle position of the inner bottom of the U-shaped frame. The inner bottom of the U-shaped frame is symmetrically provided with two rows of first lower slots for placing communication cables. The two ends of the inner bottom of the U-shaped frame are symmetrically hinged with first cover plates. The bottom of each set of first cover plates is provided with a row of first upper slots that cooperate with the first lower slots. The two sets of first cover plates are provided with two sets of first insertion holes at their close ends. The first insertion holes are provided with first fixing screws that cooperate with the first screw holes.

[0007] Through the above technical solution, the first lower slot at the bottom of the U-shaped frame carries the communication cable. The first cover plate is flipped over and covered by the hinge, so that the first upper slot at the bottom of the first cover plate is aligned with the first lower slot to clamp the cable. Then, the first fixing screw passes through the first insertion hole and is screwed into the first screw hole to lock the first cover plate and the U-shaped frame in place. This achieves the "bottom bearing and top pressing" layered and individual cable fixing of the straight section cable. Each cable corresponds to an independent slot, avoiding tangling and ensuring that a single cable can be quickly located during later maintenance.

[0008] Furthermore, the moving positioning mechanism includes a rotating base, and two sets of rotating bases are provided, with the two sets of rotating bases symmetrically hinged at both ends of the same side of the U-shaped frame. A second cover plate is hinged to the top of the rotating base near the hinge axis between the rotating base and the U-shaped frame. A row of second upper slots is evenly provided at the bottom of the second cover plate, and a row of second lower slots that cooperate with the second upper slots are evenly provided at the top of the rotating base. Two sets of second fixing screws are threaded on the top of the second cover plate away from the hinge axis between the second cover plate and the rotating base. A second screw hole that cooperates with the second fixing screw is provided on the top of the rotating base near the second fixing screw.

[0009] Through the above technical solution, the rotating base can rotate around the hinge axis with the U-shaped frame, adapting to straight or turning scenarios. In a straight scenario, the rotating base is flush with the U-shaped frame, the second lower slot carries the cable, and after the second cover plate flips, the cable is pressed through the second upper slot and then fixed by the second fixing screw into the second screw hole, forming a double fixation with the fixed positioning mechanism, enhancing the stability of the cable in the straight section. In a turning scenario, the rotating base rotates to the cable tray in another direction and repeats the above fixing action. As an adjustable auxiliary positioning module, it adapts to the cable tray rotation by adjusting the angle, and works with the bending positioning mechanism to achieve precise load bearing at the cable turning point, reducing cable bending stress.

[0010] Furthermore, the bending positioning mechanism includes strip plates, and three sets of strip plates are provided. The same end of each of the three sets of strip plates is hinged to one side of one end of the U-shaped frame. The hinge axis of the three sets of strip plates and the U-shaped frame, and the axis of the rotating base and the hinge axis of the U-shaped frame are coincident. A row of third lower slots for holding communication cables are evenly opened on the top of each strip plate. Adjacent sets of strip plates are connected by connectors, and the first and last sets of strip plates are connected to the rotating base and the U-shaped frame respectively by connectors.

[0011] Through the above technical solution, three sets of strip plates are hinged to the U-shaped frame and linked to the rotating base through the connector. When the rotating base rotates, the strip plates are driven to rotate and unfold synchronously through the connector. The third lower slot at the top of the strip plate fits the curvature of the cable as it rotates, bearing and limiting the cable of the turning section, realizing the "shape-following fixation" of the cable of the turning section. Through the linkage adjustment of the angle of the strip plate, the third lower slot is always in contact with the cable direction, reducing the stress and damage caused by the bending of the cable. At the same time, in conjunction with the fixed positioning mechanism and the moving positioning mechanism, a continuous positioning of the straight-to-turn transition section is formed to avoid the cable from loosening.

[0012] Furthermore, the connector is composed of two sets of connecting rods hinged together. The two ends of the connector are respectively hinged to two adjacent sets of strip plates, and the first and last sets of strip plates are respectively hinged to the rotating base and the U-shaped frame through the connector.

[0013] Through the above technical solution, the connector consists of two sets of hinged connecting rods, with each end hinged to an adjacent strip plate (or the strip plate and the rotating base / U-shaped frame). When the rotating base rotates, the connecting rods fold or unfold to transmit power and drive the strip plate to rotate synchronously, while maintaining the angular coordination between adjacent strip plates. As the core component for power transmission and angular constraint, it ensures the linkage stability between the rotating base and the strip plate.

[0014] Furthermore, the bottom of the strip plate on both sides away from the hinge axis of the strip plate and the U-shaped frame is symmetrically provided with a first strip groove, and the rotating base and the side of the U-shaped frame near the strip plate are both provided with a second strip groove. The first strip groove and the second strip groove are both used to accommodate the connecting rod.

[0015] With the above technical solution, when the rotating base is retracted (in a straight line scenario), the connecting rod of the connector is folded and stored in the first strip groove of the strip plate and the second strip groove of the rotating base / U-shaped frame. This avoids the connecting rod being exposed and occupying space or interfering with cable placement, thus realizing the storage function of the connector. In a straight line scenario, the device structure remains compact, avoiding unnecessary parts from affecting cable placement and fixation, and improving the space utilization and ease of use of the device.

[0016] Furthermore, the maximum included angle between two adjacent sets of strip plates is 30°, and the maximum included angle between the first and last sets of strip plates and the rotating base and the U-shaped frame is 30° respectively.

[0017] With the above technical solution, when the rotating base unfolds, the three sets of strip plates unfold at 30° increments through the linkage of the connecting parts, and the total unfolding angle can reach 30°×4=120°. The angle between the rotating base and the U-shaped frame plus the angle between the three sets of strip plates can accommodate cable tray turning angles within 120°, such as 90° and 60°. The angle of the strip plates can be adjusted synchronously according to the turning arc of the communication cable in the cable tray, so that the third lower slot always fits the cable route, realizing "shape-following fixation".

[0018] Furthermore, the first fixing structure includes second insertion holes on both sides of the U-shaped frame, and a first fixing bolt is provided inside the second insertion hole. The U-shaped frame is fixedly connected to the inner wall of the cable tray through the second insertion holes and the first fixing bolt.

[0019] Through the above technical solution, the first fixing bolts are inserted through the second insertion holes on both sides of the U-shaped frame to tighten and fix the U-shaped frame to the inner wall of the cable tray, forming a lateral connection point between the device and the cable tray, providing a foundation for the device, ensuring the stability of the U-shaped frame in the straight section or near the intersection of the curve, avoiding displacement of the device due to cable tension or external vibration, and enhancing the overall structure's resistance to deformation.

[0020] Furthermore, the second fixing structure includes a first fixing seat, which is located at one end of the rotating base. A second fixing bolt is provided on the first fixing seat, and the rotating base is fixedly connected to the inner bottom of the cable tray through the first fixing seat and the second fixing bolt.

[0021] Through the above technical solution, the first fixed seat on one side of the rotating base is tightened and fixed to the inner bottom of the cable tray by the second fixed bolt. In the straight scenario, it forms a double fixation of "inner wall + bottom" with the first fixed structure. In the turning scenario, it fixes the position of the rotating base in the cable tray in the other direction, supplements the fixing point of the device, enhances the overall stability in the straight scenario, and ensures that the rotating base is stable in the position after turning in the turning scenario, avoids the displacement of the rotating base due to the tension of the cable turning, ensures the reliability of the cable positioning in the turning section, and also helps to improve the stability of the connection between the end of the straight cable tray and the intersection of the cable tray.

[0022] Furthermore, the connecting mechanism includes a second fixing seat, which is located at one end of the first cover plate near the rotating base. Two sets of third fixing screws are provided through the top of the second fixing seat. Two sets of third screw holes that cooperate with the third fixing screws are provided on one side of the top of the second cover plate. The first cover plate is fixedly connected to the second cover plate through the second fixing seat, the third fixing screws and the third screw holes.

[0023] Through the above technical solution, the second fixing seat on the first cover plate is screwed into the third screw hole of the second cover plate by the third fixing screw, connecting the first cover plate and the second cover plate into a whole, realizing synchronous opening and closing. In straight line scenarios, the operation of the cover plate is simplified. When adding or removing cables later, only one set of screws needs to be removed to open the two sets of cover plates at the same time, without separate operation, improving maintenance convenience. At the same time, it enhances the integrity of the cover plate after it is closed, and avoids the loosening of a single set of cover plates from affecting the cable fixing effect.

[0024] The beneficial effects of the present invention are as follows: (1) The present invention adopts a double-layer limiting design of "lower slot + upper slot". In the fixed positioning mechanism, the first lower slot at the bottom of the U-shaped frame corresponds one-to-one with the first upper slot at the bottom of the first cover plate. Each set of slots can fix one cable individually. The second lower slot of the moving positioning mechanism and the second upper slot, and the third lower slot of the bending positioning mechanism are similar, forming a layout of "one cable, one fixed position". The layered and root-based fixing method makes the position of each cable clearly identifiable. During later maintenance, there is no need to disassemble all the lines. The faulty cable can be directly located, which greatly improves maintenance efficiency. At the same time, it avoids signal interference caused by cable entanglement and ensures the stability of communication transmission. (2) The present invention, through the cooperation of the moving positioning mechanism and the bending positioning mechanism, when the rotating base unfolds, the rotating base uses the connecting parts to drive the three sets of strip plates to gradually rotate and unfold. During construction, the angle of the strip plates can be adjusted synchronously according to the turning arc of the communication cable in the cable tray, so that the third lower slot always fits the cable direction, realizing "fixed according to shape", and thus realizing direct fixation. The communication cable is fixed at the bend, which reduces the stress caused by bending of the communication cable and extends its service life. At the same time, it reduces the risk of bending damage to the communication cable during construction. When the rotating base is not unfolded, the rotating base, together with the second cover plate and the fixed positioning mechanism, forms a double positioning effect, which helps to further improve the fixing effect of the communication cable in the straight cable tray. (3) The present invention achieves the connection with the cable tray through two independent fixing structures, the first fixing structure and the second fixing structure. After the rotating base is unfolded, the second fixing structure is used to fix the positioning device to the inner bottom of the cable tray intersection. Then, the first fixing structure is used to fix the positioning device to the inner wall of the cable tray near the intersection. This helps to improve the stability of the connection between the end of the straight cable tray and the intersection of the cable tray. When the rotating base of the positioning device is not unfolded, the first cover plate and the second cover plate can be connected into a whole through the connecting mechanism. When adding or removing cables later, only the screws of the corresponding cover plate need to be removed to open the first cover plate and the second cover plate together, which improves the convenience of adding or removing cables later.

Detailed Implementation

[0027] To make the objectives, technical solutions, and advantages of this invention clearer, the invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the invention.

[0028] like Figures 1-4 and Figures 8-15As shown in this embodiment, a positioning device for communication engineering construction cabling includes a U-shaped frame 1. A fixing and positioning mechanism 2 for fixing communication cables is provided on the top of the U-shaped frame 1. A movable positioning mechanism 3 for fixing communication cables is symmetrically provided at one end of the U-shaped frame 1. The fixing and positioning mechanism 2 includes two sets of first screw holes 206, located at the middle of the inner bottom of the U-shaped frame 1. Two rows of first lower slots 203 for placing communication cables are symmetrically provided on the inner bottom of the U-shaped frame 1. First cover plates 201 are symmetrically hinged to both ends of the inner bottom of the U-shaped frame 1. Each set of first cover plates 201 has a row of slots 203 connected to the first lower slots 206. The first upper slot 202 cooperates with each other. Two sets of first cover plates 201 are provided with two sets of first insertion holes 204 at their close ends. The first insertion hole 204 is provided with a first fixing screw 205 that cooperates with the first screw hole 206. The moving positioning mechanism 3 includes a rotating base 301. Two sets of rotating bases 301 are provided, and the two sets of rotating bases 301 are symmetrically hinged at both ends on the same side of the U-shaped frame 1. A second cover plate 302 is hinged to the top of the rotating base 301 near the hinge axis between the rotating base 301 and the U-shaped frame 1. A row of second upper slots 303 are evenly opened at the bottom of the second cover plate 302, and a row of slots 303 are evenly opened at the top of the rotating base 301. The second lower slot 304, which cooperates with the slot 303, has two sets of second fixing screws 305 threaded on the top of the second cover plate 302 away from the hinge axis between the second cover plate 302 and the rotating base 301. The top of the rotating base 301, near the second fixing screws 305, has a second screw hole 306 that cooperates with the second fixing screws 305. The communication cable is carried by the first lower slot 203 at the bottom of the U-shaped frame 1. After the hinged first cover plate 201 is flipped, the first upper slot 202 at the bottom is precisely aligned with the first lower slot 203, forming a clamping effect on the cable. Then, the first fixing screw 205 passes through the first insertion hole 204 and is screwed into the first screw hole 206 to complete the straight-line connection. For cable segment fixing, the rotating base 301 can rotate around the hinge axis with the U-shaped frame 1. The second lower slot 304 at the top of the base supports the cable. After the second cover plate 302 is flipped, the cable is clamped by the second upper slot 303 and the second lower slot 304. Finally, the second fixing screw 305 is screwed into the second screw hole 306 for fixing. It is suitable for straight or turning scenarios. It adopts a double-layer limiting design of "lower slot + upper slot" to achieve "one cable, one fixing position", avoiding cable tangling. In later maintenance, a single cable can be directly positioned to improve efficiency. In straight scenarios, it can form double fixing to enhance cable stability. In turning scenarios, the angle of the rotating base 301 can be adjusted to provide support for cable turning.

[0029] like Figures 5-9 and Figures 16-17As shown, in this embodiment, a bending positioning mechanism 4 is provided at one end of the U-shaped frame 1 near the moving positioning mechanism 3, which cooperates with the moving positioning mechanism 3. The bending positioning mechanism 4 includes strip plates 401, and three sets of strip plates 401 are provided. The same end of the three sets of strip plates 401 is hinged to one side of one end of the U-shaped frame 1. The hinge axis of the three sets of strip plates 401 and the U-shaped frame 1 and the axis of the rotating base 301 coincide with the axis of the hinge axis of the U-shaped frame 1. A row of third lower slots 402 for holding communication cables are evenly opened on the top of the strip plates 401. Adjacent sets of strip plates 401 are connected by connectors 403, and the first and last sets of strip plates 401 are connected by connectors 404 and 405. 3 is connected to the rotating base 301 and the U-shaped frame 1 respectively. The connecting member 403 is composed of two sets of connecting rods 4031 hinged together. The two ends of the connecting member 403 are respectively hinged to two adjacent sets of strip plates 401. The first and last sets of strip plates 401 are respectively hinged to the rotating base 301 and the U-shaped frame 1 through the connecting member 403. The bottom of the two sides of the strip plate 401 away from the hinge axis between the strip plate 401 and the U-shaped frame 1 is symmetrically provided with a first strip groove 404. The rotating base 301 and the U-shaped frame 1 are both provided with a second strip groove 405 on the side near the strip plate 401. The first strip groove 404 and the second strip groove 405 are both used to accommodate the connecting rods 4031. The two adjacent sets of strip plates The maximum included angle between the strip plates 401 is 30°. The maximum included angle between the first and last sets of strip plates 401 and the rotating base 301 and the U-shaped frame 1 is 30° respectively. The three sets of strip plates 401 are hinged to the U-shaped frame 1 and linked to the rotating base 301 through a connector 403 consisting of two sets of connecting rods 4031. When the rotating base 301 rotates, the connector 403 drives the strip plates 401 to unfold synchronously. The maximum included angle between adjacent strip plates 401 and between the strip plates 401 and the rotating base 301 / U-shaped frame 1 is 30°, forming a continuous support surface that fits the turning arc. The cable is inserted into the third lower slot 402 of the strip plate 401, adapting to the turning direction according to the angle of the strip plate. In a straight-line scenario, the connecting rod 4031 is housed in the first strip groove 404 and the second strip groove 405, maintaining a compact structure. The 30° included angle design allows the device to cover a wider range of turning angles, such as 60°, 90°, and 120° (total unfolding angle reaches 30°×4=120°), adapting to various cable tray turning requirements, especially suitable for obtuse-angle turning scenarios. The strip plate 401 unfolds synchronously with the rotating base 301, and the third lower slot 402 always conforms to the cable routing, achieving "shape-following fixation," reducing cable bending stress and lowering the risk of bending damage. The connecting rod 4031 can be housed in the strip groove, without occupying extra space in a straight-line scenario, ensuring the compact structure of the device.

[0030] like Figures 1-9 and Figures 18-19As shown, in this embodiment, the inner sides of the U-shaped frame 1 are fixedly connected to the inner wall of the cable tray via the first fixing structure 5, and the outer side of the moving positioning mechanism 3 is fixedly connected to the inner bottom of the cable tray via the second fixing structure 6. The first fixing structure 5 includes second insertion holes 501 opened on both sides of the U-shaped frame 1, and a first fixing bolt 502 is provided inside the second insertion hole 501. The U-shaped frame 1 is fixedly connected to the inner wall of the cable tray via the second insertion hole 501 and the first fixing bolt 502. The second fixing structure 6 includes a first fixing seat 601, which is located at one end of the rotating base 301. A second fixing bolt 602 is provided on the first fixing seat 601. The rotating base 301 is fixedly connected to the inner bottom of the cable tray via the first fixing seat 601 and the second fixing bolt 602. The first fixing bolt 502 is inserted into the second insertion holes 501 on both sides of the U-shaped frame 1 to fix the U-shaped frame 1 to the inner wall of the cable tray, forming a stable lateral support. The first fixing seat 601 and the second fixing bolt 602 on one side of the rotating base 301 are rotated to fix the rotating base 301 to the bottom of the inner wall of the cable tray. In a straight line scenario, it forms a double fixation of "inner wall + bottom" with the first fixing structure 5. In a turning scenario, the rotating base 301 is fixed in the position after the turn. The two sets of independent fixing structures fix the device from different directions (inner wall and bottom) to ensure stable installation in straight sections or turns, and avoid device displacement due to cable tension or vibration. In a turning scenario, the double fixation enhances the connection strength between the straight cable tray and the intersection, improves the overall structural deformation resistance, and ensures the long-term reliability of cable positioning.

[0031] like Figures 1-7 and Figures 10-11 As shown, in this embodiment, the top of the fixed positioning mechanism 2 and the moving positioning mechanism 3 are jointly provided with a connecting mechanism 7. The connecting mechanism 7 includes a second fixed seat 701, which is located at one end of the first cover plate 201 near the rotating base 301. Two sets of third fixing screws 702 are provided through the top of the second fixed seat 701. Two sets of third screw holes 703 are provided on one side of the top of the second cover plate 302, which cooperate with the third fixing screws 702. The first cover plate 201 is connected to the second cover plate 301 through the second fixed seat 701, the third fixing screws 702 and the third screw holes 703. 2. Fixed connection: The second fixing seat 701 on the first cover plate 201 is screwed into the third screw hole 703 of the second cover plate 302 by screwing the third fixing screw 702 into the second fixing seat 701, so that the first cover plate 201 and the second cover plate 302 are connected as a whole, realizing synchronous opening and closing. In a straight line scenario, the cover plate linkage design simplifies the operation. When adding or removing cables later, there is no need to disassemble the two sets of cover plates separately. Just unscrew the third fixing screw 702 to open synchronously, improving maintenance convenience. After the cover plates are connected as a whole, the stability when closing is stronger, avoiding the failure of cable fixing due to the loosening of a single set of cover plates, and further ensuring the cable positioning effect.

[0032] 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...
