Description

Technical Field

[0001] This invention relates to the field of communication cable laying technology, and in particular to a communication engineering cable positioning device. Background Technology

[0002] Laying communication cables is an essential part of communication engineering. There are a large number of communication cables, which are usually laid in cable trays on positioning frames. After a large number of cables are laid, they are in a relatively messy state in the cable trays. In order to facilitate laying and later maintenance and replacement, it is necessary to organize (cable management) and fix the position (positioning) of a large number of cables.

[0003] Currently, cable trays are commonly used when laying communication cables. These trays have a row of slots, each holding one or more cables. After the cables are laid, cable clamps are used to hold the cables in the slots in place. However, this positioning method has some drawbacks: 1. The arrangement of communication cables takes up a lot of space, which can easily cause interference; 2. When some cables need to be replaced, the arrangement of the cables can cause other cables to obstruct the removal of the current cable, making removal difficult and hindering future cable maintenance and replacement.

[0004] Therefore, the present invention proposes a cable positioning device for communication engineering. Summary of the Invention

[0005] The purpose of this invention is to provide a cable positioning device for communication engineering in order to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A communication engineering cable positioning device includes a base, a C-shaped ring fixedly disposed on one side of the base, and a combined disc clamp sleeved inside the C-shaped ring. The combined disc clamp includes a base shaft, an annular chuck, and an interleaving control component. There are two annular chucks, each sleeved outside the base shaft and inside the C-shaped ring. Both annular chucks are connected to the base shaft through the interleaving control component. The outer circumference of each annular chuck has several circumferentially evenly distributed inclined wire-passing grooves. The two annular chucks are coaxially fitted together, and the inclined directions of the inclined wire-passing grooves on them are opposite. The interleaving control component is used to control the two annular chucks to move synchronously in opposite directions and to move synchronously in the same direction relative to the C-shaped ring.

[0008] As a further description of the above technical solution:

[0009] The staggered control assembly includes a transmission sleeve, an intermediate shaft, and a switching shaft. A transmission sleeve is fixedly fitted inside each of the two annular chucks. The transmission sleeve is fitted onto the base shaft and the two are rotatably connected. One end of the intermediate shaft is rotatably connected to the outer peripheral wall of the base shaft, and its other end is fixedly connected to a bevel gear located between the transmission sleeves on the two annular chucks. One end of the transmission sleeve is fixedly connected to a bevel gear ring that meshes with the bevel gear. The switching shaft is fitted inside the base shaft and is slidably configured. This switching shaft is used to lock the intermediate shaft.

[0010] As a further description of the above technical solution:

[0011] The base shaft is a tubular structure, and the switching shaft is sleeved inside the base shaft. A limiting groove is formed on the outer peripheral wall of the switching shaft. The other end of the intermediate shaft is fixedly connected to a polygonal block extending into the limiting groove. A release groove that fits the polygonal block is formed in the middle of the limiting groove.

[0012] As a further description of the above technical solution:

[0013] It also includes an auxiliary operating unit, which includes a gate-shaped insert rod and a gate-shaped trigger rod. Two free ends of the gate-shaped insert rod are fixedly connected to cantilever arms, and the free ends of the cantilever arms are fixedly connected to insert shafts. The gate-shaped trigger rod is slidably disposed in the middle of the gate-shaped insert rod and both are in the same plane. Two free ends of the gate-shaped trigger rod are provided with elastic hooks. Both ends of the base shaft are fixedly fitted with transmission platforms. Several circumferentially evenly distributed slots are opened on the outer periphery of the transmission platform. The slots and the transmission platform are inserted and engaged. The other end of the transmission platform is fixedly connected to a transmission disc. Several circumferentially evenly distributed hanging grooves are opened on the surface of the transmission disc. The hanging grooves and the elastic hooks are engaged and engaged.

[0014] As a further description of the above technical solution:

[0015] The top view projection of the portal-shaped plug rod is Z-shaped. A guide sleeve is fixedly connected to the crossbeam at the top of the portal-shaped plug rod. The vertical rod on the portal-shaped trigger rod is sleeved in the guide sleeve. One end of the hanging groove extends to the outer peripheral wall of the transmission disc.

[0016] As a further description of the above technical solution:

[0017] The auxiliary operating part includes a lead screw, one end of which is rotatably connected to the top of the crossbeam, and a threaded sleeve is fixedly installed on the crossbar of the gantry trigger rod, which is sleeved on the outside of the lead screw.

[0018] As a further description of the above technical solution:

[0019] Both of the two annular chucks have arc-shaped grooves on opposite sides. A pad is fixedly connected to one end of the arc-shaped groove, and a support spring located in the arc-shaped groove is connected between the pads on the two annular chucks.

[0020] As a further description of the above technical solution:

[0021] The annular chuck and the C-ring are fitted with a clearance and are axially detachable. One end of the base is welded with a support plate that is fixedly connected to the outer arc wall of the C-ring. Both sides of the support plate are fixedly connected with a stop shaft. One end of the stop shaft is bolted to a stop plate for limiting the position of the annular chuck.

[0022] In summary, due to the adoption of the above technical solution, the beneficial effects of the present invention are:

[0023] 1. In this invention, by setting up a combination disc clamp, an inclined wire guide groove and a C-shaped ring, the combination disc clamp is provided with two annular chucks, so that multiple cables will be positioned in multiple inclined wire guide grooves on the outer periphery of the annular chucks respectively, and the multiple cables are distributed around the annular chucks. This setting greatly reduces the space occupied after the cables are laid, and the multiple cables are distributed more neatly.

[0024] 2. In this invention, the C-shaped ring is configured to cooperate with the annular chuck that rotates within the C-shaped ring, so that each cable can move to the notch on the C-shaped ring and then be disassembled and replaced from the notch. This configuration ensures that when the current cable is disassembled and replaced, other cables are kept away, thus making it more convenient to replace a single cable.

[0025] 3. In this invention, by setting up an interleaved control component and a support spring, the cable has the function of being clamped and fixed, which improves the stability of the cable positioning. Moreover, the interleaved control component also has the function of simultaneously releasing the clamped cable, thereby reducing the resistance of the annular chuck rotation and making it easier for the supported cable to be disassembled and replaced after following the rotation of the annular chuck.

[0026] 4. In this invention, an auxiliary operation unit is provided, which makes the rotation operation of the annular chuck more labor-saving, thereby making cable replacement more convenient and greatly reducing the labor intensity of the operator.

[0027] 4. In this invention, the C-shaped ring and the combination disc clamp for fixing the cable have a splitting function. At the point where the C-shaped ring is detached, the combination disc clamp can separate a large number of communication cables for transmission, avoid them from getting tangled together, and improve the neatness of the cable laying.

Detailed Implementation

[0039] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0040] Example 1

[0041] Please see Figure 1-8 A communication engineering cable positioning device includes a base 1 with mounting holes for easy connection to an external cable frame via screws. A C-ring 11 is fixedly installed on one side of the base 1, with a notch on the C-ring 11 serving as a cable inlet and outlet. A combination disc clamp 2 is fitted inside the C-ring 11, which positions the cables and fixes them around the combination disc clamp 2.

[0042] Specifically, the combination disc clamp 2 includes a base shaft 21, an annular chuck 22, and an interlacing control component 23. There are two annular chucks 22, both of which are fitted outside the base shaft 21 and inside the C-ring 11. The annular chucks 22 and the C-ring 11 are rotatably engaged. Several circumferentially evenly distributed inclined wire-passing grooves 221 are provided on the outer periphery of the annular chucks 22. The two annular chucks 22 are coaxially fitted, and the inclined wire-passing grooves 221 on the two are inclined in opposite directions. The inclined wire-passing grooves 221 are radially inclined relative to the annular chucks 22. When in use, the two annular chucks 22 are controlled to rotate so that the inclined wire-passing grooves 221 on the two can form a wire hole and a notch. When forming a wire hole, the cable passing through the wire hole can be limited. When forming a notch, the cable can easily be disengaged from the notch. When the two annular chucks 22 are controlled to rotate synchronously and in the same direction until the notch and the notch of the C-ring 11 are opposite, the cable and the device can be easily disassembled and installed. The wire hole and notch are formed by controlling two annular chucks 22 to rotate synchronously in opposite directions.

[0043] Furthermore, both annular chucks 22 are connected to the base shaft 21 via an interleaved control component 23. The interleaved control component 23 is used to control the synchronous reverse movement of the two annular chucks 22 and their synchronous same-direction movement relative to the C-shaped ring 11. In other words, the combination and separation of multiple cables and this device can be controlled through the interleaved control component 23 and the base shaft 21.

[0044] Specifically, the staggered control assembly 23 includes a transmission sleeve 231, an intermediate shaft 232, and a switching shaft 233. The transmission sleeve 231 is fixedly sleeved inside each of the two annular chucks 22. The transmission sleeve 231 is sleeved on the base shaft 21 and the two are rotatably connected. One end of the intermediate shaft 232 is rotatably connected to the outer peripheral wall of the base shaft 21, and the other end is fixedly connected to a bevel gear 2321 located between the transmission sleeves 231 on the two annular chucks 22. The intermediate shaft 232 is perpendicular to the base shaft 21. One end of the transmission sleeve 231 is fixedly connected to a bevel gear ring 2311 that meshes with the bevel gear 2321. At this time, when the base shaft 21 is fixed and one of the annular chucks 22 is rotated, the other annular chuck 22 will rotate in the opposite direction under the transmission of the bevel gear ring 2311 and the bevel gear 2321.

[0045] The switching shaft 233 is fitted inside the base shaft 21 and is slidably configured. This switching shaft 233 is used to lock the intermediate shaft 232. When the intermediate shaft 232 is locked, the bevel gear 2321 cannot rotate. When the base shaft 21 is rotated, the two transmission sleeves 231 will be simultaneously driven to rotate in the same direction. Therefore, when it is necessary to control the two annular chucks 22 to rotate in opposite directions, the intermediate shaft 232 needs to be pulled; when it is necessary to control the two annular chucks 22 to rotate synchronously in the same direction, the intermediate shaft 232 needs to be reset.

[0046] Furthermore, the base shaft 21 is a tubular structure, and the switching shaft 233 is sleeved inside the base shaft 21. The outer peripheral wall of the switching shaft 233 is provided with a limiting groove 2331. The other end of the intermediate shaft 232 is fixedly connected to a polygonal block 2322 extending into the limiting groove 2331. In this embodiment, the polygonal block 2322 is a square block. The middle part of the limiting groove 2331 is provided with a release groove 23311 that is in clearance fit with the polygonal block 2322. That is, when the switching shaft 233 slides until the polygonal block 2322 enters the release groove 23311, the intermediate shaft 232 is in a state where it is not restricted from rotating. Conversely, the polygonal block 2322 will be limited by the limiting groove 2331 and cannot rotate.

[0047] In this embodiment, the annular chuck 22 and the C-shaped ring 11 are clearance-fitted and axially detachable. A support plate 12 is welded to one end of the base 1 and fixedly connected to the outer arc wall of the C-shaped ring 11. A stop shaft 121 is fixedly connected to both sides of the support plate 12. A stop plate 6 for limiting the position of the annular chuck 22 is connected to one end of the stop shaft 121 by a bolt 5. The end of the stop shaft 121 is provided with a threaded hole connected to the bolt 5. After the stop plate 6 is removed, the combined disc clamp 2 and the C-shaped ring 11 can be easily separated. The disassembled combined disc clamp 2 can be used to separate and position multiple cables. That is to say, the combined disc clamp 2 can be installed at equal intervals on the cables so that multiple cables are in a separated state after being laid.

[0048] The two annular chucks 22 each have an arc-shaped groove 222 on opposite sides. A pad 2221 is fixedly connected to one end of the arc-shaped groove 222. A support spring 3 located in the arc-shaped groove 222 is connected between the pads 2221 on the two annular chucks 22. The purpose of this arrangement is to facilitate the two annular chucks 22 to elastically clamp the cable using the inclined wire groove 221. In other words, when the notch appears, the support spring 3 will be compressed.

[0049] Example 2

[0050] Please see Figure 1 , Figure 5 , Figure 6 and Figure 9 The difference from Embodiment 1 is that it also includes an auxiliary operation unit 4. The function of the auxiliary operation unit 4 is to assist the operator in controlling the rotation of the base shaft 21 and the annular chuck 22, thereby reducing the labor intensity of the operator.

[0051] Specifically, the auxiliary operation unit 4 includes a gate-shaped insert rod 41 and a gate-shaped trigger rod 42. Two free ends of the gate-shaped insert rod 41 are fixedly connected to cantilever arms 411, and the free ends of the cantilever arms 411 are fixedly connected to insert shafts 4111. The gate-shaped trigger rod 42 is slidably disposed in the middle of the gate-shaped insert rod 41, and both are in the same plane. Two free ends of the gate-shaped trigger rod 42 are provided with elastic pins 421. The elastic pins 421 adopt a common limit pin structure with built-in springs, and the limit pins are in an extended state. Transmission platforms 211 are fixedly sleeved at both ends of the base shaft 21. Several circumferentially evenly distributed slots 2111 are opened on the outer periphery of the transmission platform 211. These slots 2111 and the transmission platform 211 are inserted into each other. The two insert shafts 4111 on the gate-shaped insert rod 41 are inserted into the slots 2111 on both sides of the staggered control component 23. Then, swinging the gate-shaped insert rod 41 controls the rotation of the base shaft 21, thereby facilitating the synchronous and unidirectional rotation of the two annular chucks 22. The other end of the transmission sleeve 231 is fixedly connected to a transmission disc 2312. The surface of the transmission disc 2312 is provided with several circumferentially evenly distributed hanging slots 23121. The hanging slots 23121 are engaged with the elastic hanging pins 421. That is, when the insert shaft 4111 is inserted into the slot 2111, the elastic hanging pins 421 are then controlled to insert into the hanging slots 23121, which controls the gate-shaped insert rod 41 and the gate-shaped trigger rod 42 to move closer. At this time, the elastic hanging pins 421 can push the transmission disc 2312 to rotate. It should be noted that the two transmission discs 2312 rotate in different directions, thereby controlling the two annular chucks 22 to rotate synchronously in different directions.

[0052] Furthermore, the top view projection of the portal-shaped insert 41 is Z-shaped. This design facilitates the synchronous but opposite rotation of the two annular chucks 22 without interfering with the cables. It also facilitates the insertion of the insert shaft 4111 and the slot 2111, as well as the docking of the elastic hanging pin 421 and the hanging groove 23121. A guide sleeve 41011 is fixedly connected to the crossbeam 4101 at the top of the portal-shaped insert 41. The vertical rod 4201 on the portal-shaped trigger rod 42 is fitted inside the guide sleeve 41011. One end of the hanging groove 23121 extends to the outer peripheral wall of the transmission disk 2312. This design facilitates the disengagement of the hanging groove 23121 from the elastic hanging pin 421 after it moves. In other words, when the elastic hanging pin 421 pushes the transmission disk 2312 to rotate to a certain angle through the corresponding hanging groove 23121, it will disengage from the hanging groove 23121, which facilitates the separation of the entire auxiliary operation unit 4.

[0053] Furthermore, the auxiliary operation unit 4 includes a lead screw 43, one end of which is rotatably connected to the top of the crossbeam 4101. A threaded sleeve 42021 is fixedly provided on the crossbar 4202 of the gate-shaped trigger rod 42, which is sleeved outside the lead screw 43. The lead screw 43 makes it easier to control the relative movement between the gate-shaped insert rod 41 and the gate-shaped trigger rod 42.

[0054] Working principle: Taking the fixed installation of base 1 as an example, when multiple cables need to be positioned, first control the base shaft 21 to rotate so that the inclined wire passage grooves 221 on the two annular chucks 22 (the two inclined wire passage grooves 221 form wire holes) are close to the notch at the top of the C-ring 11. Then pull the switching shaft 233 to release the lock on the intermediate shaft 232. Then control the two annular chucks 22 to rotate in the opposite direction. At this time, the inclined wire passage grooves 221 on the two annular chucks 22 form notches with their openings facing the notch at the top of the C-ring 11. The cable is fed into the notch through the notch. Control the base shaft 21 to rotate to switch other notches to face the notch at the top of the C-ring 11. Then place another cable. In this way, all the cables can be installed. After all the cables are placed, control the two annular chucks 22 to rotate in the opposite direction and reset the switching shaft 233 to lock the intermediate shaft 232. At this time, the current cable is positioned.

[0055] The above description is only a preferred embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and inventive concept of the present invention, should be covered within the scope of protection of the present invention.
