[0021] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0022] like Figure 1-7 As shown, a cable fixing device for communication engineering includes a lower fixing seat 1, an upper fixing seat 2, an adjustment mechanism 3 and a wire pressing mechanism 4. The lower fixing seat 1 is detachably connected to the upper fixing seat 2 by bolts. The inner cavities of the lower fixing seat 1 and the upper fixing seat 2 are correspondingly provided with an active cavity 5 that cooperates with the adjustment mechanism 3. The lower cavity of the active cavity 5 is a curved surface structure. The wire pressing mechanism 4 is threadedly connected to the upper fixing seat 2.

[0023] The adjustment mechanism 3 includes two sets of slide plates 31 symmetrically arranged in the active cavity 5. The slide plates 31 are used to adjust the range of wire pressing. The two sets of slide plates 31 are slidably connected to the inner wall of the active cavity 5. The sides of the two sets of slide plates 31 in contact with the cable are arc-shaped structures. The arc-shaped structures enable the two sides of the cable to fit more closely to the surface of the slide plates 31 when pressing the cable.

[0024] The wire pressing mechanism 4 includes a telescopic plate 41, which is used to squeeze and fix the cable. The telescopic plate 41 is an arc-shaped structure. The arc-shaped structure enables the top of the cable to fit more closely to the surface of the telescopic plate 41 when pressing the cable. Both ends of the telescopic plate 41 slide on the outer wall of the slide plate 31. The top of the telescopic plate 41 is rotatably connected to a pressure rod 42. The pressure rod 42 is used to adjust the height of the wire pressing mechanism 4. The pressure rod 42 is threadedly connected to the upper fixed seat 2. The top of the pressure rod 42 is threadedly connected to a limiting column 43. The limiting column 43 is used to prevent the wire pressing mechanism from detaching from the upper fixed seat 2.

[0025] Furthermore, mounting grooves 51 are symmetrically opened on both sides of the inner wall of the upper cavity portion of the movable cavity 5, and a plurality of support columns 52 are fixedly installed in the mounting grooves 51. Two groups of adjustment cavities 32 are symmetrically opened in the middle position near the top of the slide plate 31, and an elastic component 33 is fixedly installed at one end of the adjustment cavity 32 near the center. The corresponding adjustment cavities 32 at the two ends of the top of the slide plate 31 are symmetrically connected with slide grooves 34, and an L-shaped adjustment rod 35 is slidably connected in each group of slide grooves 34. One end of the L-shaped adjustment rod 35 is located at the top of the movable end of the adjustment mechanism 33, and the other end of the L-shaped adjustment rod 35 is clamped above the support column 52. The side wall of the upper fixed seat 2 is symmetrically opened with a clamping groove for matching the installation of the L-shaped adjustment rod 35.

[0026] From the above description, it can be seen that the support column 52 is used to support the L-shaped adjustment rod 35, the elastic component 33 is used to realize the clamping work of the L-shaped adjustment rod 35, and the L-shaped adjustment rod 35 is used to fix the height of the slide plate 31. Through the cooperation of the elastic component 33, the L-shaped adjustment rod 35 and the support column 52, the two ends of the upper top of the slide plate 31 can be fixed on the support column 52 at a height adapted to the size of the cable, thereby improving the stability of the device when pressing the cable.

[0027] Furthermore, the telescopic plate 41 includes an arc-shaped fixed plate 411, the top of the arc-shaped fixed plate 411 is rotatably connected to the pressure rod 42, two groups of telescopic cavities 412 are symmetrically opened at both ends of the arc-shaped fixed plate 411, the inner wall of the telescopic cavity 412 is slidably connected with an arc-shaped movable plate 413, and the two side walls of the arc-shaped movable plate 413 are symmetrically provided with limit blocks 414, and the two sides of the telescopic cavity 412 are matched with the limit blocks 414 to open a first arc groove 415, and handles 44 are symmetrically installed on both sides of the limit column 43.

[0028] From the above description, it can be seen that the arc-shaped movable plate 413 can always form a complete cable top extrusion arc surface with the slide plate 31, thereby increasing the extrusion area of ​​the cable and making the wire pressing more stable. The limit block 414 is used to prevent the arc-shaped movable plate 413 from separating from the arc-shaped fixed plate 411. The function of the handle 44 is to make the rotating limit column 43 drive the entire wire pressing mechanism 4 to squeeze the cable downward more labor-saving.

[0029] Furthermore, the elastic component 33 includes a spring 331 , one end of which is fixedly mounted on a side of the adjustment chamber 32 away from the slide slot 34 , and the other end of the spring 331 is fixedly connected to the adjustment plate 332 , so that the spring 331 is always in a compressed state.

[0030] It can be known from the above description that the spring 331 always applies pressure to the adjustment plate 332 , and thus the adjustment plate 332 always applies pressure to the L-shaped adjustment rod 35 at its top.

[0031] Furthermore, pulleys 36 are symmetrically arranged at both ends of the bottom of the slide plate 31 , and a second arc groove 53 for sliding with the pulley 36 is opened on the inner wall of the lower cavity of the movable cavity 5 .

[0032] From the above description, it can be known that by providing the pulley 36, the contact friction area between the bottom of the slide plate 31 and the lower fixed seat 1 is reduced when sliding, thereby increasing the service life of the device.

[0033] The working principle of the utility model is described as follows:

[0034] First install the lower fixing seat 1 at the specified position, then screw the pressure rod 42 upward into the upper fixing seat 2, then install the limit column 43 on its top, then clamp the cable at the top center of the lower fixing seat 1, and then install the upper fixing seat 2 with bolts to complete the preliminary installation of the entire device.

[0035] The two L-shaped adjusting rods 35 on one of the slide plates 31 are then pressed toward the middle position, so that the end of the L-shaped adjusting rod 35 away from the adjusting plate 332 is completely returned to the slide groove 34. At this time, the two L-shaped adjusting rods 35 simultaneously squeeze the adjusting plate 332 toward the middle, and then the adjusting plate 332 simultaneously squeezes the spring 331 toward the middle. At this time, the spring 331 is further in a compressed state. Then, the pulleys 36 at both ends of the bottom of the slide plate 31 are first installed in the second arc groove 53, and then the L-shaped adjusting rod 35 is released after adjusting upward to a suitable height according to the size of the cable. Then, the adjusting plate 332 is squeezed toward both sides by the elasticity of the spring 331. Then, the adjusting plate 332 is forced to squeeze the L-shaped adjusting rod 35 toward both sides, so that the end of the L-shaped adjusting rod 35 away from the adjusting plate 332 exits the slide groove 34 and is then stuck on the support column 52. The other slide plate 31 repeats this operation to complete the size adjustment of the entire device when fixing the cable.

[0036] Finally, the handle 44 is rotated, and then the pressure rod 42 drives the telescopic plate 41 to press the cable downward to fix it in the device, completing the entire cable fixing step.
