The limiting plate is slidably connected to the wire pay-off reel body through a limiting groove, and the guide rod is slidably connected to the rotating disk through a guide groove, and the guide groove is inclined. The above application document can rotate the rotating disk by pushing the push rod, so that the guide rod can slide in the guide groove, and at the same time, the limiting plate can slide in the limiting groove until the block on the outside of the limiting plate is stuck in the groove on the inside of the cable reel. Through the above operation, the auxiliary support limit of the cable reel can be achieved, so that the cable reel can be prevented from self-deflecting due to the tension generated by the wire pay-off. At the same time, it can be applicable to the auxiliary support limit of cable reels with various inner diameters, with a wide range of applications, and the process does not require the use of a wrench, and the operation process is simple and quick.

[0004] Although the above application document can prevent the cable roll from deflecting due to tension by pushing the push rod, in actual use, since the staff usually need to arrange the cables at a distance from the support frame, it takes a lot of manpower to only use the push rod to lay the cables. Therefore, a cable laying device is proposed to solve the above problem. Utility Model Content

DETAILED DESCRIPTION

[0033] 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 in 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.

[0034] Reference Figure 1 , Figure 2 and Figure 4 The utility model provides an embodiment: a cable laying device, including a base plate 1, the bottom end of the base plate 1 is flat, and the inner wall of the base plate 1 is provided with a through hole fixed to the ground. The way the base plate 1 is fixed to the ground is the prior art and will not be described in detail in this case. Mounting plates 2 are fixedly connected to the left and right sides of the top of the base plate 1. The number of mounting plates 2 is set to two, and the shapes and materials of the two mounting plates 2 are the same. A roller 3 is provided at one end of the two mounting plates 2 close to each other, and the diameters of the two sides of the roller 3 are larger than the middle diameter. A cable body 4 is provided on the outside of the roller 3, and one end of the cable body 4 is fixedly connected to the outer wall of the roller 3, and the other parts of the cable body 4 are wound around the outer wall of the roller 3.

[0035] Reference Figure 3 - Figure 5 The mounting plate 2 is connected to the roller 3 through a connecting assembly 5, which includes a slide groove 51. The shape of the slide groove 51 is approximately a rectangular parallelepiped. The slide groove 51 is opened at one end of the two mounting plates 2 that are close to each other. The slide grooves 51 opened on the inner walls of the left and right mounting plates 2 are in the same horizontal area. The inner wall of the slide groove 51 is slidably connected with a slider 52. The height of the slider 52 matches the height of the slide groove 51. The surface of the slider 52 is smooth. The front end of the slider 52 is elastically connected to the inner wall of the slide groove 51 through a spring 53. One end of the spring 53 is fixedly connected to the front end of the slider 52, and the other end of the spring 53 is fixedly connected to the inner wall of the slide groove 51. The setting of the spring 53 ensures that when the roller 3 and the slider 52 are not subjected to force, the slider 52 can be maintained at the rearmost end of the slide groove 51 under the elastic force of the spring 53.

[0036] Reference Figure 3 , Figure 5 and Figure 6 The inner wall of the slider 52 passes through and is rotatably connected with a rotating block 54, which is in the shape of a cylinder. The outer wall of the rotating block 54 is fixedly connected to the outer wall of the drum 3, and the circles of the side view corresponding to the rotating block 54 and the drum 3 are concentric circles. A fixing component 6 is arranged inside the rotating block 54, and the fixing component 6 includes a mounting groove 61, which is arranged on the inner wall of the rotating block 54. A starting block 62 is slidably connected to the inner wall of the rotating block 54, and the shape of the starting block 62 is similar to a shape formed by connecting a cylinder and a truncated cone, and the truncated cone part of the starting block 62 is at the end away from the drum 3, and the diameter of the truncated cone part of the starting block 62 close to the drum 3 is consistent with the diameter of the cylinder, and the diameter of the side away from the drum 3 is smaller than the diameter of the cylinder. The shape setting of the starting block 62 ensures that the starting block 62 can enter the mounting groove 61 after being thrust in the front and rear directions.

[0037] Reference Figure 3 , Figure 4 and Figure 6 The end of the starting block 62 close to the drum 3 is elastically connected to the inner wall of the mounting groove 61 through a spring 2 63, one end of the spring 2 63 is fixedly connected to the end of the starting block 62 close to the drum 3, and the other end of the spring 2 63 is fixedly connected to the inner wall of the mounting groove 61. The elastic force of the spring 1 53 is much greater than the elastic force of the spring 2 63. A connecting rod 64 is hinged on the outer wall of the starting block 62. The initial state of the connecting rod 64 is a horizontal state. The end of the connecting rod 64 away from the starting block 62 is hinged on a fixed block 65. The shape of the fixed block 65 is a cylinder. A fixing hole 66 is provided on the inner wall of the slider 52. The shape of the fixing hole 66 matches the shape of the fixed block 65. A moving hole 67 is provided on the inner wall of the mounting plate 2. The setting of the moving hole 67 ensures that when the starting block 62 moves forward, there is space to move in the direction away from the drum 3, thereby achieving the expected effect.

[0038] Reference Figure 5 and Figure 7The interior of the fixed block 65 is provided with a deceleration assembly 7, which includes a moving bin 71, the shape of which is approximately a shape formed by a cylindrical groove and two rectangular grooves connected together, the moving bin 71 is opened on the inner wall of the fixed block 65, and a baffle 72 is slidably connected to the inner wall of the moving bin 71, the shape of the baffle 72 is approximately a shape formed by a cylinder and two rectangular blocks and a hemisphere connected together, and the hemispherical shape of the baffle 72 is located on the outer side of the moving bin 71, and the shape setting of the baffle 72 ensures that there are rounded objects on the outer sides of the baffle 72 and the fixed block 65, so as to achieve the effect of facilitating the baffle 72 and the fixed block 65 to enter the fixing hole 66, and the outer wall of the baffle 72 protrudes away from the connecting rod 64 and is elastically connected to the inner wall of the moving bin 71 by a spring three 73, one end of the spring three 73 is fixedly connected to the end of the outer wall of the baffle 72 protruding away from the connecting rod 64, and the other end of the spring three 73 is fixedly connected to the inner wall of the moving bin 71.

[0039] Working principle: During use, when a worker who is far away from the bottom plate 1 needs to release the line, the worker pulls the cable body 4, so that the cable body 4 is subjected to a force to move forward, thereby driving the roller 3 to move forward, so that the slider 52 moves forward driven by the roller 3.

[0040] When the slider 52 moves forward so that the starting block 62 and the moving hole 67 are at the same horizontal position, the starting block 62 enters the moving hole 67 under the elastic force of the spring 2 63. At this time, the starting block 62 drives the connecting rod 64 to move, so that the connecting rod 64 tilts, thereby reducing the projection length of the connecting rod 64 at the same horizontal position as the fixed block 65, so that the fixed block 65 moves in the direction close to the starting block 62, so that the starting block 62 leaves the fixed hole 66.

[0041] When the starting block 62 leaves the fixing hole 66, the rotating block 54 can rotate relative to the slider 52, so the drum 3 can rotate at this time, and the cable body 4 can achieve the wire-releasing effect during the rotation of the drum 3. When the force pulling the cable body 4 is small, since the drum 3 and the slider 52 cannot move forward, the rotating block 54 will be fixed by the fixing block 65 and cannot rotate relative to the slider 52. Therefore, the cable body 4 will not release the wire due to the small force, thereby achieving the effect of preventing the drum 3 from rolling and releasing the wire by itself.

[0042] At the same time, in the normal process of paying out the wire, when the drum 3 rotates at a faster speed, the centrifugal force applied to the baffle rod 72 is relatively large. Therefore, at this time, the baffle rod 72 can overcome the elastic force of the spring three 73 and move in the direction away from the starting block 62. When the baffle rod 72 enters the fixing hole 66 or makes the edge of the baffle rod 72 contact with the edge of the fixing hole 66 under the drive of the centrifugal force, there is resistance when the rotating block 54 continues to rotate. Therefore, the rotation speed of the rotating block 54 can be slowed down to achieve deceleration, thereby preventing the occurrence of excessive cable payout and ensuring the payout effect.

[0043] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent substitutions for some of the technical features therein. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
