Description

Technical Field

[0001] This utility model belongs to the field of cable fixing technology, and in particular relates to a cable fixing device for laying communication cables. Background Technology

[0002] A cable fixing device is a device or tool used to fix, organize, and protect cables (such as optical fibers, coaxial cables, twisted pairs, etc.) during the laying process.

[0003] For example, Chinese patent CN206947910U discloses a cable fastener for building pipelines. This device uses clips on the fastener to secure the cables, making the cable paths clear and distinct. It can not only clearly distinguish the cables and prevent them from becoming messy, but also facilitate real-time monitoring of the pipelines.

[0004] When this patent uses elastic clips to fix communication cables, the elastic clips have a limited range of elastic deformation, so they can only fix communication cables of a certain size. Moreover, after long-term use, the elastic clips become weak and are prone to detachment, resulting in unstable fixing of the communication cables. Utility Model Content

[0005] The purpose of this utility model is to provide a cable fixing device for laying communication cables to solve the problems mentioned in the background art, including: The frame has several mounting holes inside, which can be used with bolts to install the frame at the location to be used. The frame also has an adjustment port inside. An adjustment assembly, part of which is disposed within an adjustment port, includes several limiting frames. The limiting frames and the frame surface can form a space to accommodate communication cables. The several limiting frames can be moved simultaneously to press communication cables of different sizes.

[0006] Preferably, the adjustment component further includes: The cam is located inside the adjustment port; A driving component that can drive the cam to rotate; Several plates are in contact with the surface of the cam; Several rods are fixedly installed on several plates respectively, the rods pass through the frame, and the limiting frame is fixedly installed on the rods; Several first elastic elements are able to push the plate and cam to maintain contact by means of their own elasticity.

[0007] Preferably, the cam is rhomboid in shape.

[0008] Preferably, the limiting frame is U-shaped, so that the limiting frame can clamp and fix two communication cables at the same time.

[0009] Preferably, the first elastic element is a first spring, which is sleeved around the rod body. The two ends of the first spring are fixed to the plate body and the frame body respectively, and the first spring is located on the side of the plate body away from the cam.

[0010] Preferably, the driving component is a knob, which can be rotated by an external force. The cam and the knob are fixed together by a rotating shaft, and the rotating shaft is rotatably connected to the frame.

[0011] Preferably, the outer wall of the knob in the circumferential direction is provided with a plurality of grooves, which can increase the contact area between the knob and the outside world.

[0012] Preferably, the outer wall of the knob in the circumferential direction is provided with a plurality of positioning grooves, and a positioning component is provided inside one of the positioning grooves, the positioning component being able to restrict the rotation of the knob.

[0013] Preferably, the frame has an internal cavity, and part of the positioning component is installed inside the cavity.

[0014] Preferably, the positioning component includes: A positioning rod that passes through the frame and the cavity, the positioning rod being able to be inserted into one of the positioning slots; A sliding plate is fixedly installed on the outer wall of the positioning rod, and the sliding plate is slidably installed in the cavity. The pull ring is fixedly mounted on the positioning rod. The second elastic element is a second spring that can push the slide plate closer to the positioning groove by its own elasticity. The second spring is sleeved around the positioning rod and is located on the side of the slide plate away from the positioning groove. The two ends of the second spring are fixed to the slide plate and the frame respectively.

[0015] This application uses a drive component to rotate a cam. When the cam rotates, the contact position between the plate and the cam changes, and the diameter from the contact surface between the plate and the cam to the center of the cam gradually decreases. At this time, the first elastic element pushes the plate to maintain contact with the cam. Simultaneously, the plate moves closer to the cam, and the plate moves the rod closer to the cam. The rod moves the limit frame closer to the cam. At the same time, the limit frame clamps and fixes communication cables of different diameters between the limit frame and the frame surface. Due to the U-shaped design of the limit frame, the communication cables cannot detach. Attached Figure Description

Detailed Implementation

[0018] The technical solutions of the embodiments of this application will be clearly described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this application. All other embodiments obtained by those skilled in the art based on the embodiments of this application are within the scope of protection of this application.

[0019] To address the issues of size and cable disconnection, this embodiment provides a cable fastener for laying communication cables, such as... Figure 2 As shown, it includes: a frame 100 and an adjustment assembly 200. Different sized communication cables are fixed by simultaneously moving several limiting brackets 250 of the adjustment assembly 200.

[0020] like Figure 2 As shown, the frame 100 (U-shaped) has four mounting holes 110 inside (located on the protrusions of the U-shaped edge). The mounting holes 110 can be used with bolts to install the frame 100 at the location to be used. The frame 100 also has an adjustment port 120 (rectangular) inside.

[0021] Continue as Figure 2 As shown, part of the adjustment component 200 is disposed within the adjustment port 120, such as... Figure 3 As shown, the adjustment assembly 200 includes six limiting frames 250, which can form a space with the surface of the frame 100 to accommodate communication cables. The six limiting frames 250 can be moved simultaneously to press communication cables of different sizes. Specifically, the adjustment assembly 200 also includes: a cam 210, a drive member 220, six plates 230, six rods 240, and six first elastic members 260.

[0022] Among them, cam 210 is diamond-shaped (the advantage of the diamond shape is that it can drive such as...) Figure 3 The upper and lower multiple sets of plates 230 shown are arranged in the adjustment port 120; the driving component 220 can drive the cam 210 to rotate, and the driving component 220 is a knob (such as...). Figure 4As shown), the knob can be rotated by external force. The cam 210 and the knob are fixed together by a rotating shaft. The rotating shaft and the frame 100 are rotatably connected by a bearing. Six plates 230 (square) are in contact with the surface of the cam 210. Six rods 240 (square rods) are respectively fixedly installed on the side of the six plates 230 away from the cam 210. The rods 240 pass through the frame 100 and can slide along the frame 100. The limiting frame 250 is fixedly installed at the end of the rod 240. The limiting frame 250 is in the shape of a square rod. The U-shaped rod 240 is installed at the center of the U-shape. This design allows the limiting frame 250 to clamp and fix two communication cables simultaneously, improving the load-bearing capacity of the device. Six first elastic elements 260 can use their own elasticity to push the plate 230 and the cam 210 to maintain contact. The first elastic element 260 is a first spring, which is sleeved around the rod 240. The first spring is located on the side of the plate 230 away from the cam 210, and the two ends of the first spring are fixed to the plate 230 and the frame 100, respectively.

[0023] When it is necessary to fix communication cables of different sizes, such as Figure 3 In the state shown, the communication cable to be fixed is first placed between the surface of the limiting frame 250 and the frame 100. Then, the rotating drive 220 drives the cam 210 to rotate (before the cam 210 rotates, the two longest diameter surfaces of the rhombus are in contact with the plate 230). When the cam 210 rotates, the contact position between the plate 230 and the cam 210 will change. The diameter from the contact surface of the plate 230 and the cam 210 to the center of the cam 210 gradually decreases. At this time, the first elastic element 260 will push the plate 230 to maintain contact with the cam 210. At the same time, the plate 230 moves closer to the cam 210. The plate 230 drives the rod 240 to move closer to the cam 210. The rod 240 drives the limiting frame 250 to move closer to the cam 210. At the same time, the limiting frame 250 clamps and fixes the communication cables of different diameters between the limiting frame 250 and the surface of the frame 100. Due to the U-shaped design of the limiting frame 250, the communication cable cannot be detached.

[0024] To reduce slippage when using the knob, a further solution, such as... Figure 4 As shown, the outer wall of the knob in the circumferential direction is provided with a plurality of grooves 221. The grooves 221 can increase the contact area between the knob and the outside world. The increased contact area between the hand and the knob increases the friction and makes it less likely to slip.

[0025] To prevent the communication cable from being over-clamped due to the cam 210 being pushed and rotated by the plate 230 without external support, a further solution is, such as Figure 4As shown, the outer wall of the knob in the circumferential direction is also provided with a number of positioning grooves 222 (square), and a positioning component 300 is provided inside one of the positioning grooves 222. The positioning component 300 can restrict the rotation of the knob. Specifically, the frame 100 is provided with a cavity 130 (rectangular), and part of the structure of the positioning component 300 is installed in the cavity 130. The positioning component 300 includes: a positioning rod 310, a sliding plate 320, a pull ring 330, and a second elastic element 340.

[0026] The positioning rod 310 (a square long rod) passes through the frame 100 and the cavity 130, and can be inserted into one of the positioning slots 222; the sliding plate 320 (square) is fixedly installed on the outer wall of the positioning rod 310, and the sliding plate 320 is slidably installed in the cavity 130 and positioned in the cavity 130 near the positioning slot 222; the pull ring 330 (square) is fixedly mounted on the top of the positioning rod 310 and can be pulled by external force; the second elastic element 340 can push the sliding plate 320 closer to the positioning slot 222 by its own elasticity. The second elastic element 340 is a second spring, which is sleeved around the positioning rod 310 and is located on the side of the sliding plate 320 away from the positioning slot 222. The two ends of the second spring are fixed to the sliding plate 320 and the frame 100, respectively.

[0027] When the knob needs to be used, pull the pull ring 330 to move the positioning rod 310 out of the positioning groove 222. At this time, the positioning rod 310 drives the slide plate 320 to compress the second elastic element 340. Then, the knob can be used normally. When the knob is finished, release the pull ring 330. The second elastic element 340 pushes the slide plate 320 to drive the positioning rod 310 into the positioning groove 222, thereby limiting the rotation of the knob and preventing the cam 210 from being pushed by the plate 230 to rotate without external support, which would cause the communication cable to be over-clamped.

[0028] The embodiments of this application have been described above with reference to the accompanying drawings. Unless otherwise specified, the embodiments and features in the embodiments of this application can be combined with each other. This application is not limited to the specific embodiments described above. The specific embodiments described above are merely illustrative and not restrictive. Those skilled in the art can make many other forms under the guidance of this application without departing from the spirit and scope of the claims, and all of these forms are within the protection scope of this application.
