[0017] In order to make the purpose, technical solution and advantages of the embodiments of the present invention clearer, the technical solution in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0018] A cable bracket for communication construction, such as Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6As shown, it includes a mounting plate 1, on which are provided several insertion holes 2, in which the insertion holes 2 are slidably fitted with insertion rods 3, the upper end of the insertion rod 3 is installed with a same support plate 8, the support plate 8 is an arc-shaped plate, which can better fit the cable, and the mounting plate 1 is provided with a clamping device for clamping the cable; the clamping device includes a transverse axis 4, and the transverse axis 4 is rotatably installed on both sides of the mounting plate 1, the transverse axis 4, the support plate 8 and the mounting plate 1 are arranged in parallel, with one end at the front and the other end at the back, and the clamping plates 5 are fixedly installed on the transverse axis 4 by connecting rods, and coaxial gear rings 6 are respectively installed on the transverse axis 4, and a rack 7 is meshingly fitted on one side of the gear ring 6, and the rack 7 can only move up and down relative to the mounting plate 1, and the rack 7 is installed on the insertion rod 3, and the mounting plate 1 is provided with a limiting mechanism for limiting the upward reset of the rack 7. The present invention has a simple structure and an ingenious design. The clamping plate 5 for fixing the cable is set on the mounting plate 1. When fixing the cable, it is only necessary to place the cable on the support plate 8, and by pressing the cable, the cable drives the support plate 8 to move downward, and at the same time the clamping plate 5 closes to clamp and fix the cable. The operation is convenient, and the degree of closing of the clamping plate 5 is different according to the different diameters of the cables, so as to meet the clamping and fixing of cables of different diameters. The present invention has strong applicability, can meet actual needs, and is suitable for promotion. When using the present invention, first install the mounting plate 1 in an appropriate position. When installing the cable, the clamping plate 5 is rotated back to open, and then the cable to be installed is placed on the support plate 8, and pressure is applied to the cable or the support plate 8, so that the support plate 8 drives the insertion rod 3 to move downward, the insertion rod 3 drives the rack 7 to move downward, the rack 7 drives the gear ring 6, the horizontal axis 4 and the clamping plate 5 to rotate, and the clamping plates 5 on both sides rotate towards each other and close, so that the cable is clamped between the clamping plates 5 and the support plate 8 on both sides. The limit mechanism limits the rack 7 to move upward and reset, and the clamping plate 5 will not rotate back to open, so as to keep the cable clamped and fixed; When it is necessary to remove the cable support plate 8, the limit mechanism is adjusted to release the limit on the rack 7, the rack 7 can move upward, the clamping plate 5 is rotated back to open, and the support plate 8 is moved upward to reset for the next use; since the speed at which the clamping plates 5 rotate toward each other and close is greater than the speed at which the support plate 8 moves downward, when the clamping plate 5 clamps and fixes the cable, there is no need for the support plate 8 to be in low contact with the mounting plate 1, and the cable is clamped and fixed between the clamping plate 5 and the support plate 8. At this time, the support plate 8 continues to move downward, and the clamping force on the cable continues to increase, so it can meet the clamping and fixation of cables of different diameters.

[0019] Specifically, if Figure 1 , Figure 2 and Figure 5As shown, the limiting mechanism described in this embodiment includes a limiting gear 20, one of the racks 7 is meshed with the limiting gear 20, the limiting gear 20 is rotatably connected to one end of the spring telescopic rod 21 through a one-way bearing, the other end of the spring telescopic rod 21 is fixedly connected to the mounting plate 1, the spring telescopic rod 21 includes an inner rod and an outer tube, the inner rod is slidably installed in the outer tube, the inner rod can only slide relative to the outer tube and cannot rotate in the outer tube, a reset spring is provided between the inner rod and the outer tube, under the action of the reset spring, the spring telescopic rod 21 maintains an extended state, so that the limiting gear 20 maintains meshing with the rack 7, the inner rod is fixedly connected to the inner ring of the one-way bearing, the outer ring of the one-way bearing is fixedly connected to the limiting gear 20, and the outer tube is fixedly connected to the mounting plate 1. The limit gear 20 is meshed with the rack 7. When the rack 7 moves downward, it can drive the limit gear 20 to rotate forward. The one-way bearing does not hinder the limit gear 20 from rotating forward, and the limit gear 20 rotates forward relative to the spring telescopic rod 21; when the rack 7 moves upward to reset, due to the action of the one-way bearing, the limit gear 20 cannot rotate reversely relative to the spring telescopic rod 21, so the rack 7 cannot move upward to reset; when it is necessary to move the rack 7 upward to reset, the limit gear 20 is pushed to compress the spring telescopic rod 21, and the limit gear 20 is gradually separated from the rack 7, thereby releasing the restriction of the limit gear 20 on the rack 7; through the cooperation between the rack 7 and the limit gear 20, the rack 7 can be continuously limited, thereby increasing the applicability of fixing cables of different diameters.

[0020] Specifically, Figure 1 and Figure 2 As shown, the outer periphery of the plug rod 3 of this embodiment is equipped with a thrust spring 50, one end of the thrust spring 50 is in contact with the bottom side of the support plate 8, and the other end is in contact with the top side of the mounting plate 1. Under the action of the thrust spring 50, the support plate 8 can be moved upward and reset, and the clamping plate 5 can be in an open state, so that the cable can be placed on the support plate 8 when installed.

[0021] Further, such as Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 and Figure 6 As shown, the clamping plate 5 described in this embodiment is a C-shaped plate, and the circles where the C-shaped plates on the left and right sides are coaxially arranged, and a row of several avoidance grooves 60 are respectively opened on the adjacent sides of the C-shaped plates on both sides, and the C-shaped plate is provided with a plurality of protrusions 61 on one side of the avoidance groove 60 and cross-distributed with the avoidance groove 60 in the front and back, and the avoidance grooves 60 on the C-shaped plates on the left and right sides are cross-distributed in the front and back. When the clamping plates 5 on the left and right sides are closed, the protrusions 61 of the C-shaped plate extend into the corresponding avoidance grooves 60, forming a protective cover above the cable to protect the cable.

[0022] Furthermore, Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 As shown, the inner side of the protrusion 61 described in this embodiment is respectively fixedly connected to one end of the fixing rope 70, and the other end of the fixing rope 70 is fixedly connected to the corresponding C-shaped plate. The length of the fixing rope 70 is greater than the straight-line distance between the two ends of the fixing rope 70. In this embodiment, the length of the fixing rope 70 is 1.5 times the straight-line distance between the two ends of the fixing rope 70, so that the fixing rope 70 can be distributed along the curved surface of the cable, so that the fixing rope 70 can fit with cables of different diameters. The fixing rope 70 is tilted, so that when the fixing rope 70 fits with the cable, it is spirally distributed, increasing the fitting area between the fixing rope 70 and the cable. When the clamp 5 clamps and fixes the cable, the clamp 5 does not directly contact the cable. The clamp 5 fixes and clamps the cable through the fixing rope 70. The clamp 5 and the cable are in soft contact, and the fixing rope 70 fits better with the cable, which can be applied to the fixing of cables of more diameters, increasing applicability.

[0023] Furthermore, Figure 1 , Figure 2 and Figure 5 As shown, the lower part of the outer periphery of the plug rod 3 described in this embodiment is provided with an external thread, and the thread is matched with the mounting nut 80, the rack 7 is fixedly connected with the nut 80 through a connecting rod, the upper end of the plug rod 3 is rotatably connected with the support plate 8 through a bearing, and a stopper 81 is fixedly provided on the mounting plate 1, and the bottom side of the support plate 8 is in contact with the upper end of the stopper 81. When the support plate 8 moves to the bottom, it is in contact with the stopper 81; the rack 7 is movably connected with the plug rod 3 through the nut 80 and the external thread on the plug rod 3, and the height of the rack 7 on the plug rod 3 can be adjusted, thereby adjusting the distance between the support plate 8 and the stopper 81, and then the degree of closing of the clamp plate 5 can be adjusted.

[0024] Furthermore, Figure 3 , Figure 4 and Figure 5As shown, the transverse axis 4 described in this embodiment is rotatably mounted on the mounting plate 1 through a sleeve 90, and the gear ring 6 is fixedly mounted on the outer periphery of the sleeve 90. The gear ring 6 and the sleeve 90 are coaxially arranged, and the outer periphery of the transverse axis 4 is movably sleeved on the sleeve 90. The sleeve 90 is rotatably mounted on the mounting plate 1 through a bearing, and the sleeve 90 is fixedly connected to the inner ring of the bearing, and the outer ring of the bearing is fixedly connected to the mounting plate 1. The transverse axis 4 can rotate in the sleeve 90 and can move back and forth relative to the sleeve 90. A compression spring 91 is provided between the sleeve 90 and the corresponding transverse axis 4, and the compression spring 91 is sleeved on the outer periphery of the transverse axis 4. One end of the compression spring 91 is in contact with one end of the sleeve 90, and the other end is in contact with a retaining ring. The retaining ring is fixed on the transverse axis 4, and V-shaped grooves 92 are respectively provided on the outer periphery of the transverse axis 4. Slide rods 93 are slidably installed in the V-shaped grooves 92, and the slide rods 93 are fixed on the sleeve 90. Under the elastic thrust of the compression spring 91, the slide bar 93 is located in the middle of the V-shaped slide groove 92. When the cable receives a forward or backward pulling force, the cable drives the clamping plate 5 and the horizontal axis 4 to move forward or backward through the friction force. The horizontal axis 4 moves forward or backward relative to the sleeve 90, and the slide bar 93 slides in the V-shaped slide groove 92, which can make the sleeve 90 have a tendency to rotate in the opposite direction. The sleeve 90 drives the gear ring 6 to rotate in the opposite direction, and the rack 7 moves upward. Because the rack 7 cannot move upward and reset under the action of the limit mechanism, the sleeve The tube 90 cannot rotate in the opposite direction, so the horizontal axis 4 drives the clamping plate 5 to rotate in the forward direction, and the clamping plate 5 moves toward the cable, thereby increasing the clamping effect on the cable, forming a tightening effect. That is, when the cable drives the clamping plate 5 and the horizontal axis 4 to slide back and forth relative to the mounting plate 1 through friction, the clamping force of the clamping plate 5 on the cable increases, thereby preventing the cable from being separated from the clamping plate 5; when the forward or backward pulling force on the cable is cancelled, the above process is performed in reverse order, and the clamping force of the clamping plate 5 on the cable is reduced, thereby avoiding damage to the cable caused by long-term high-strength clamping of the cable.

[0025] Furthermore, Figure 1 and Figure 6 As shown, the mounting plate 1 of this embodiment is fixedly mounted with a fixing plate 31 through a connecting plate 30, and a mounting hole 32 is provided on the fixing plate 31. Bolts are passed through the mounting holes 32 to mount the fixing plate 31 at an appropriate position, thereby completing the fixing of the mounting plate 1.

[0026] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or make equivalent replacements for some of the technical features therein. However, these modifications or replacements do not deviate the essence of the corresponding technical solutions from the spirit and scope of the technical solutions of the embodiments of the present invention.
