DETAILED DESCRIPTION

[0027] The following is a combination of specific implementation cases and attached Figures 1 to 4 The present invention is further described below, but the present invention is not limited to these embodiments.

[0028] The existing device lacks sudden drop protection measures. Once the rope used to provide lifting power breaks, the fixed base and the cable will fall freely to the ground, causing damage to the fixed base and the cable. Figures 1 to 4 As shown, a communication cable support device with an adjustment mechanism is proposed, including a support frame 1, an outer wall of the support frame 1 is provided with a lifting seat 2 which slides up and down through a lifting mechanism, the outer wall of the support frame 1 is provided with a blocking mechanism for protecting the lifting seat 2, and multiple groups of blocking mechanisms are provided in the vertical direction. The lifting seat 2 can be blocked by the multiple groups of blocking mechanisms, and a limit rod 4 is fixedly installed in the inner cavity of the support frame 1 in the horizontal direction, and two first movable plates 5 are slidably sleeved on the outer wall of the limit rod 4. The two first movable plates 5 are symmetrically arranged with the vertical center line of the limit rod 4 as the axis, and the blocking mechanism is installed on the outer wall of the first movable plate 5. The movement of the first movable plate 5 can cause the blocking mechanism to be retracted into the inner cavity of the support frame 1.

[0029] See also Figure 2 and Figure 3 As shown, the blocking mechanism includes an elastic damper 7 installed on the side wall of the first movable plate 5. The elastic damper 7 is an existing component. Under the action of external force, the elastic damper 7 undergoes elastic deformation and returns to its initial state when the external force is removed. It also includes a stopper 8 installed on the outer wall of the elastic damper 7. The stopper 8 slides outward and penetrates the outer wall of the support frame 1, and the outer wall of the stopper 8 is arranged to be inclined downward from the outside to the inside. The inclined end surface of the stopper 8 can ensure that when the lifting seat 2 moves upward to touch the stopper 8, the stopper 8 is automatically retracted into the inner cavity of the support frame 1 without the need for other external force driving, and when the lifting seat 2 moves upward to completely separate from the outer wall of the stopper 8, the stopper 8 can automatically extend outward under the elastic force of the elastic damper 7 to prepare for blocking and protecting the lifting seat 2. The design is ingenious and reasonable; specifically, the stoppers 8 on the left and right sides are arranged on the same horizontal line to ensure that the blocking force of the stoppers 8 on the left and right sides of the lifting seat 2 is balanced, so as to prevent the lifting seat 2 from tilting to one side.

[0030] See also Figure 2 and Figure 3 As shown, a driving rod 6 is vertically installed at the bottom end of the first movable plate 5, and the driving rod 6 slides outward and penetrates the outer wall of the support frame 1. The arrangement of the driving rod 6 and the first movable plate 5 can cause the blocks 8 on both sides to be synchronously retracted into the inner cavity of the support frame, so as to lift the lifting seat 2 that has descended to the bottom end of the outer wall of the support frame 1 to the top end of the support frame 1 to support the cables. The protective support of the block 8 is reusable, which can save application costs compared with the disposable block 8.

[0031] See also Figure 2 and Figure 4 As shown, the left and right sides of the lifting seat 2 are respectively provided with support mechanisms, and each group of support mechanisms realizes the support and positioning of two groups of cables; each group of support mechanisms includes a fixing frame 9 fixedly installed on the outer wall of the lifting seat 2, and the fixing frame 9 is provided with a slide groove 10 in the vertical direction. The inner wall of the slide groove 10 is rotatably connected with a screw rod 11, and the upper and lower sides of the outer wall of the screw rod 11 are provided with threads in opposite directions and symmetrically, and the upper and lower sides of the outer wall of the screw rod 11 are respectively threadedly sleeved with a second movable plate 12, and the bottom end of the outer wall of the second movable plate 12 is provided with a first positioning component, and the outer wall of the lifting seat 2 is provided with a relative position to the first positioning component The corresponding second positioning assembly can realize the formation of a closed positioning space between the first positioning assembly and the second positioning assembly through the supporting mechanism; the first positioning assembly includes a first connecting rod 13 installed on the outer wall of the second movable plate 12, and the outer wall of the first connecting rod 13 is installed with a first positioning claw 14; the second positioning assembly includes a second connecting rod 15 installed on the outer wall of the lifting seat 2, and the outer wall of the second connecting rod 15 is installed with a second positioning claw 16, and the second positioning claw 16 corresponds to the position of the first positioning claw 14; the positioning of the cable is realized by the docking of the first positioning claw 14 and the second positioning claw 16;

[0032] Place the cable in the inner cavity of the space formed by the first positioning claw 14 and the second positioning claw 16, drive the screw 11 to rotate, and the screw 11 drives the second movable plate 12 symmetrically threaded on the upper and lower sides of the outer wall to move synchronously toward the middle, so as to prompt the first connecting rod 13 connected to the outer wall of the second movable plate 12 and the first positioning claw 14 to move synchronously toward the middle, until the first positioning claw 14 and the second positioning claw 16 form a closed space, so as to position and support the cable in the inner cavity of the second positioning claw 16.

[0033] In addition, a guide rod 17 is installed on the side of the fixed frame 9 opposite to the outer wall of the lifting seat 2, and the second movable plate 12 is slidably mounted on the outer wall of the guide rod 17, thereby ensuring that when the second movable plate 12 moves, it can move along the outer wall of the guide rod 17 and guide the displacement direction of the second movable plate 12.

[0034] A base 18 is installed at the bottom end of the support frame 1, and a universal wheel 19 is installed at the bottom end of the base 18. The arrangement of the universal wheel 19 can enable the entire device to be moved and transported to a suitable position, and the use is flexible and convenient.

[0035] In the present application, the lifting mechanism is the same as the mechanism used to lift the fixed seat in the patent with announcement number CN213093840U, and no further details are given here. It is sufficient that it can drive the lifting seat 2 to lift in the vertical direction.

[0036] The working principle of a communication cable support device with an adjustment mechanism in this embodiment is as follows:

[0037] When the lifting seat 2 is in free fall under an unexpected situation, it will first slow down under the blocking action of the top stopper 8 in the process of sliding down along the outer wall of the support frame 1. If the top stopper 8 is broken by the impact of the lifting seat 2, the lifting seat 2 will continue to move downward after slowing down, and will continue to slow down under the action of the middle layer stopper 8. As a result, under the blocking action of the layer-by-layer stopper 8, the lifting seat 2 is gradually decelerated and stops sliding down, thereby protecting the lifting seat 2 and the cables positioned at the top of the lifting seat 2 and preventing them from directly hitting the ground; and the inclined end face of the stopper 8 can ensure that when the lifting seat 2 moves upward to touch the stopper 8, the stopper 8 is automatically retracted into the inner cavity of the support frame 1 without the need for other external force driving, and when the lifting seat 2 moves upward to completely separate from the outer wall of the stopper 8, the stopper 8 can automatically extend outward under the elastic force of the elastic damper 7 to prepare for blocking and protecting the lifting seat 2. The design is ingenious and reasonable.

[0038] When positioning and supporting two groups of cables in the vertical direction, the cables are placed in the inner cavity of the space formed by the first positioning claw 14 and the second positioning claw 16, and the screw 11 is driven to rotate. The screw 11 drives the second movable plate 12 symmetrically threaded on the upper and lower sides of the outer wall to move synchronously toward the middle, so as to cause the first connecting rod 13 and the first positioning claw 14 connected to the outer wall of the second movable plate 12 to move synchronously toward the middle, until the first positioning claw 14 and the second positioning claw 16 form a closed space, so as to position and support the cables in the inner cavity of the second positioning claw 16;

[0039] The utility model can block and receive the sudden drop of the lifting seat 2 layer by layer, and block and protect the lifting seat 2 that falls freely in an unexpected situation, so as to prevent the lifting seat 2 and the supporting device from directly hitting the ground, so as to protect the cables and the lifting seat 2, and the protection of the block 8 is reusable, which can save application cost compared with the disposable block 8. In addition, two groups of cables corresponding to the upper and lower cables can be positioned synchronously, the number of cables positioned is more, and the positioning requirements can be better met, and the step of realizing the synchronous positioning of the two cables by the same driving force is more convenient.

[0040] The above description is only the preferred embodiment of the utility model, and is not intended to limit the utility model. For those skilled in the art, the utility model can have various modifications and changes. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the utility model shall be included in the protection scope of the utility model.
