In order to ensure the normal operation of a wireless communication system, a signal transmitting antenna is generally arranged at the highest point of a communication tower to increase the service radius, thereby achieving an ideal communication effect. The communication tower is generally laid with a device for supplying power to or transmitting signals from the signal transmitting antenna, and the cable is fixed by adopting the cable fixing device, so that the cable is prevented from being broken due to collision between the wind swing and the main body of the communication tower.

In the related art, the cable fixing device generally adopts a bolt fastening mode to fix the cable, and when the cable is laid, the bolt is required to be screwed by using tools such as a wrench, a screwdriver and the like, so that the cable is fixed, the operation is complex, and the laying efficiency of the cable is low.

Based on this, an embodiment of the present utility model provides a fixing device 100 for fixing a cable, as shown in fig. 1, and fig. 1 is a schematic diagram of the overall structure of the fixing device according to some embodiments of the present utility model. The fixture 100 comprises a mounting tube 1, two clamps 2 and a plurality of elastic restoring assemblies 3.

Referring to fig. 2, fig. 2 is a front view of a mounting tube according to some embodiments of the present utility model. The mounting tube 1 has an axis extending in a first direction. The mounting tube 1 is provided with two through holes 11 coaxially arranged, and the axial directions of the two through holes 11 are perpendicular to the first direction. That is, the mounting tube 1 is provided with one through hole 11 at opposite sides thereof, respectively, and the two through holes 11 extend along the same axis, which is perpendicular to the axis of the mounting tube 1.

It will be appreciated that the cross section of the mounting tube 1 parallel to the first reference plane may be a circular ring, a rectangular ring, or other regular or irregular shapes, which may be specifically selected according to the actual situation, and this disclosure is not limited specifically. The first reference surface is perpendicular to the axis of the mounting tube 1.

Illustratively, as shown in fig. 1, the cross section of the mounting tube 1 parallel to the first reference surface may be a circular ring, e.g. the mounting tube 1 is a circular tube. The arrangement in this way is beneficial to reducing the space inside the installation tube 1, and can perform preliminary guiding and limiting on the cable when the cable is penetrated, thereby improving the laying efficiency of the cable; on the other hand, the space occupied by the installation tube 1 can be reduced, and the space utilization rate is improved.

Referring to fig. 3, fig. 3 is a cross-sectional view of a fixture at the axis of a through hole provided in some embodiments of the present utility model. The two clamping members 2 are respectively inserted into the two through holes 11, that is, one clamping member 2 is disposed in each through hole 11, and one end of the clamping member 2 extends to the inner side of the mounting tube 1 and the other end extends to the outer side of the mounting tube 1.

Wherein the clamping member 2 is movable in the axial direction of the through hole 11 (Z direction as shown in fig. 1) between a first position and a second position. When the clamping members 2 are in the first position, the distance between the two clamping members 2 is smaller than the radial dimension of the cable; when the clamping members 2 are in the second position, the spacing between the two clamping members 2 is larger than the radial dimension of the cable.

It will be appreciated that when the cable is laid, the portion of the clamping member 2 located outside the installation tube 1 may be pulled to move the clamping member 2 from the first position to the second position, and when the distance between the two clamping members 2 is greater than the radial dimension of the cable, the cable may be threaded between the two clamping members 2. At this time, the clamp 2 is moved in a direction approaching the first position, so that the clamp 2 can be brought into contact with the cable, and the cable can be clamped between the two clamps 2.

In this manner, the fixing device 100 can be adapted to more size cables, which is advantageous in improving versatility of the fixing device 100.

On this basis, referring to fig. 1, each elastic restoring assembly 3 is connected to one clamping member 2 and the installation tube 1, and at least one elastic restoring assembly 3 is provided between each clamping member 2 and the installation tube 1. That is, the elastic restoring assembly 3 is disposed between the grip 2 and the mounting tube 1, and is connected with the corresponding grip 2 and mounting tube 1.

When the clamping member 2 is in the first position, the elastic restoring member 3 is in a natural state. That is, the elastic restoring member 3 is not elastically deformed when the clip 2 is in the first position. The resilient restoring assembly 3 is arranged to provide a restoring force to the clamp 2 directed from the second position to the first position when the clamp 2 is in the second position or between the first position and the second position. That is, when the clamping member 2 moves from the first position toward the second position, the elastic restoring member 3 is elastically deformed, and provides a restoring force to the clamping member 2 from the second position toward the first position.

In this way, after the cable is threaded between the two clamps 2 and the force applied to the clamps 2 is removed, the two clamps 2 will move against the cable and provide a pressing force to the cable under the restoring force provided by the elastic restoring assembly 3. In this way, the cable is clamped between the two clamping members 2, and the cable is fixed.

It will be appreciated that only one elastic restoring assembly 3 may be provided between each clamping member 2 and the mounting tube 1, or a plurality of elastic restoring assemblies 3 may be provided, and this may be specifically selected according to the actual situation, which is not specifically limited in the present disclosure.

Illustratively, as shown in fig. 3, two elastic restoring assemblies 3 are provided between each clip 2 and the mounting tube 1, and the two elastic restoring assemblies 3 are provided on both sides of the through hole 11 and symmetrically disposed with respect to the axis of the through hole 11.

In this way, the clamping member 2 can be stressed more uniformly, which is beneficial to improving the fixing effect of the fixing device 100 and improving the stability of cable installation.

Illustratively, as shown in fig. 1, the fixing device 100 further includes a connection plate 4, one end of the connection plate 4 is connected to the mounting tube 1, and the other end is used for connection to a communication tower. Thus, the fixing device 100 can be fixed to the communication tower, and the cable can be fixedly mounted by the fixing device 100.

When the fixing device 100 provided by the utility model is used for fixing a cable, the distance between two clamping pieces 2 can be larger than the radial dimension of the cable only by applying a force to the clamping pieces 2 to enable the clamping pieces 2 to move from the first position to the second position. At this time, the cable is threaded between the two clamping members 2, and the acting force applied to the clamping members 2 is removed, so that the clamping members 2 can move towards the direction close to the first position under the action of the elastic recovery assembly 3, thereby clamping the cable between the two clamping members 2. The cable fixing device can fix the cable, is simple to operate, does not need tools, and is beneficial to improving the laying efficiency of the cable.

In some embodiments, as shown in fig. 4, fig. 4 is an enlarged view of the fixing device at the through hole according to some embodiments of the present utility model. The elastic restoring assembly 3 includes a stopper rod 31, a sleeve 32, and a compression spring 33. The limit rod 31 is connected with one of the mounting tube 1 and the corresponding clamping piece 2; the sleeve 32 is sleeved on the limit rod 31 and is connected with the other one of the mounting tube 1 and the corresponding clamping piece 2.

That is, in the case where the stopper rod 31 is connected to the mounting tube 1, the sleeve 32 is connected to the corresponding clip 2; the sleeve 32 is connected to the mounting tube 1 in the case that the stop bar 31 and the corresponding clamp will be connected. Specifically, the selection may be performed according to actual situations, and this disclosure is not limited specifically.

Illustratively, as shown in fig. 4, the stop bars 31 are connected with the corresponding clamps 2, and the bushings 32 are connected with the mounting tube 1.

Wherein the stop lever 31 is movable relative to the sleeve 32 in the axial direction of the through hole 11. The compression spring 33 is sleeved on the part of the limit rod 31, which is positioned outside the sleeve 32, and one end, which is close to the sleeve 32, is connected with the sleeve 32.

In this way, the compression spring 33 is compressed when the clamping member 2 moves from the first position to the second position, so that the compression spring 33 provides a restoring force to the clamping member 2 from the second position to the first position. The structure is simple and easy to realize.

It will be appreciated that the compression spring 33 may also be fitted over the sleeve 32 with one end in contact with the mounting tube 1 and the other end in contact with the clamp 2. Specifically, the selection may be performed according to actual situations, and this disclosure is not limited specifically.

In some embodiments, as shown in fig. 3, the clamp 2 includes a clamp portion 21 and an operating portion 22. The clamping portion 21 is provided inside the mounting tube 1, and has a dimension in the radial direction of the through hole 11 at least partially larger than the aperture of the through hole 11. In this way, when the clip 2 is fitted to the mounting tube 1, the clip 2 is prevented from moving to the outside of the mounting tube 1 through the through hole 11 and falling off from the mounting tube 1. In this way, the assembly efficiency of the fixing device 100 is advantageously improved. In addition, the contact area between the clamping piece 2 and the cable is increased, and the stability of cable fixation is improved.

The operation portion 22 is inserted into the corresponding through hole 11 and connected to the holding portion 21.

The operation portion 22 and the clamping portion 21 may be integrally formed; or two mutually independent components can be connected into a whole through welding, screw connection, bonding and other modes. Specifically, the selection may be performed according to actual situations, and this disclosure is not limited specifically.

Illustratively, as shown in fig. 3, the operating portion 22 is integrally formed with the clamping portion 21. In this way, not only the connection strength between the operation portion 22 and the clamping portion 21 can be improved, thereby improving the structural strength of the clamping member 2 and prolonging the service life of the first clamping member 2; the production process of the clamping piece 2 can be simplified, and the production efficiency of the clamping piece 2 can be improved.

Wherein the operating part 22 is located outside the installation tube 1 at an end remote from the clamping part 21. That is, an end of the operating portion 22 remote from the clamping portion 21 is exposed outside the installation tube 1. Thus, when the fixing device 100 is used to fix the cable, the clamping portion 21 can be moved from the first position to the second position by pulling the operation portion 22, so that the operation is convenient, and the cable laying efficiency can be improved.

It will be appreciated that in the case where the stopper includes the operation portion 22 and the grip portion 21, the elastic restoring member 3 may be disposed between the grip portion 21 of the corresponding grip 2 and the mounting tube 1, with one end connected to the mounting tube 1 and the other end connected to the grip portion 21 of the grip 2.

On this basis, in the case where the stopper rod 31 is connected to the corresponding clip 2 and the sleeve 32 is connected to the mounting tube 1, the compression spring 33 is provided on the side of the sleeve 32 near the clip portion 21 of the clip 2. When the clamping member 2 is in the first position, the compression spring 33 is in a natural state and is in contact with the clamping member 2 at an end remote from the sleeve 32.

In some embodiments, as shown in fig. 3, the clamping member 2 further includes a handle 23, where the handle 23 is disposed on a side of the operating portion 22 away from the clamping portion 21, and is connected to the operating portion 22.

In this way, the grip portion 21 can be moved from the first position to the second position by pulling the handle 23, which is advantageous for further improving the laying efficiency of the cable.

Illustratively, as shown in FIG. 3, the handle 23 is semi-circular in shape. It will be appreciated that the handle 23 may be formed in a third ring, a two-thirds ring, a rectangular frame, etc., and may be specifically selected according to practical situations, which is not specifically limited in this disclosure.

The handle 23 and the operation portion 22 may be integrally formed; or two mutually independent components can be connected into a whole through welding, screw connection, bonding and other modes. Specifically, the selection may be performed according to actual situations, and this disclosure is not limited specifically.

Illustratively, as shown in fig. 3, the handle 23 is integrally formed with the operating portion 22. In this way, not only the connection strength of the handle 23 and the operation portion 22 can be improved, thereby improving the structural strength of the clamping member 2 and prolonging the service life of the clamping member 2; the production process of the clamping piece 2 can be simplified, and the production efficiency of the clamping piece 2 can be improved.

In some embodiments, as shown in fig. 3, the cross section of the clamping portion 21 parallel to the first reference surface is a fan ring curved toward the approaching operation portion 22, i.e., the cross section of the clamping portion 21 parallel to the first reference surface may be regarded as a part of a circular ring, that is, the surfaces of the two clamping portions 21 approaching each other are curved surfaces.

In this way, when clamping the cable between the two clamping portions 21, the two clamping members 2 can play a limiting role to limit the movement of the cable between the two clamping members 2, thereby reducing the risk of the cable being detached from between the two clamping members 2, which is advantageous for improving the reliability of the cable fixation.

In some embodiments, as shown in fig. 4, clip 2 further includes a cushion 24, cushion 24 being disposed on a side of clip portion 21 (shown in fig. 3) remote from handle portion 22 (shown in fig. 3) and coupled to clip portion 21 (shown in fig. 3). By providing the cushion 24, the outer skin of the cable can be protected, which is beneficial to reducing the risk of breakage of the cable.

Cushion 24 may be a rubber cushion, a foam polystyrene cushion, or the like having elasticity. Specifically, the selection may be performed according to actual situations, and this disclosure is not limited specifically.

In some embodiments, referring to fig. 5, fig. 5 is a partial cross-sectional view of a fixation device at a sleeve provided in some embodiments of the present utility model. The fixture 100 further comprises a guide rod 5 and a sleeve 6. The guide rod 5 is disposed between two clamping portions 21 (shown in fig. 3) of the two clamps 2 (shown in fig. 3) and the inner wall of the installation tube 1 (shown in fig. 3), and is connected to one of the two clamping portions 21. The sleeve 6 is sleeved on the guide rod 5 and is connected with the other of the two clamping parts 21. The guide rod 5 is movable relative to the sleeve 6 in the axial direction of the through hole 11.

Wherein, set up guide bar 5 between two clamping parts 21 of two clamping pieces 2 and the inner wall of installation tube 1, can avoid guide bar 5 to cause the interference to the cable when wearing to establish the cable, be favorable to improving the laying efficiency of cable. In addition, the guide rod 5 and the sleeve 6 can prevent the cable from deviating from between the two clamping pieces 2 when the cable is threaded, which is beneficial to further improving the laying efficiency of the cable.

In this way, the guide rod 5 and the sleeve 6, which are mutually matched, can limit and guide the two limiting members, preventing the clamping members 2 from deflecting when moving along the axial direction of the through hole 11, thereby reducing the risk of dislocation of the two clamping members 2 and improving the fixing effect of the fixing device 100.

It will be appreciated that the fixture 100 may also include a plurality of guide rods 5 and a plurality of sleeves 6, with one sleeve 6 corresponding to each guide rod 5. Specifically, the selection may be performed according to actual situations, and this disclosure is not limited specifically.

The fixing device 100 comprises, for example, two guide rods 5 and two sleeves 6, one sleeve 6 being provided on each guide rod 5, and the two guide rods 5 being provided on either side of the through hole 11. In this way, the risk of deflection of the two clamping members 2 can be further reduced, thereby improving the fixing effect of the fixing device 100.

In some embodiments, as shown in fig. 3, the fixation device 100 further comprises two guiding structures 7. Two guide structures 7 are provided on the outside of the mounting tube 1, and each guide structure 7 is connected to one clamping member 2.

The guide structure 7 comprises two guide plates 71, two sliding blocks 72 and two connecting rods. Two guide plates 71 are connected to the mounting tube 1 and located on opposite sides of the through hole 11. The guide plate 71 is provided with a slide groove 711, and the slide groove 711 extends in the second direction, and the second direction, the first direction, and the axial direction of the through hole 11 are perpendicular to each other. Each slide 72 corresponds to one slide slot 711 and is slidably connected to the corresponding slide slot 711. Each connecting rod corresponds to one sliding block 72, one end of each connecting rod is rotationally connected with the corresponding sliding block 72, and the other end of each connecting rod is rotationally connected with the clamping piece 2.

Thus, when the holder 2 moves from the first position to the second position, the slider 72 moves in the second direction in a direction approaching the through hole 11; when the holder 2 moves from the second position to the first position, the slider 72 moves in the second direction in a direction away from the through hole 11.

In this way, the guiding structure 7 can guide the clamping piece 2 to move along the axial direction of the through hole 11, so that the risk that the clamping piece 2 interferes with the wall of the through hole 11 in the moving process is reduced, and the clamping piece 2 can move more smoothly. In this way, the force is saved when the clamping member 2 is pulled.

Illustratively, the chute 711 is a T-shaped slot, and the shape of the slider 72 is adapted to the shape of the chute 711.

On this basis, as shown in fig. 4, the guide structure 7 further includes rollers 8 and a rotation shaft. The roller 8 is disposed between the slider 72 and the chute 711, and is in contact with the slider 72 and the chute 711. The roller 8 is provided with a shaft hole, and a rotating shaft is arranged in the shaft hole in a penetrating way and is connected with the sliding block 72. The roller 8 is rotatable about a rotation axis.

In this way, the friction force applied when the slider 72 slides relative to the chute 711 can be reduced, thereby making the operation of the fixing device 100 more labor-saving.

The foregoing is merely illustrative of the present utility model, and the present utility model is not limited thereto, and any person skilled in the art will readily recognize that variations or substitutions are within the scope of the present utility model. Therefore, the protection scope of the present utility model shall be subject to the protection scope of the claims.
