Detailed implementation manners

[0019] Next, in combination with the accompanying drawings in the embodiments of the present utility model, the technical solutions in the embodiments of the present utility model will be clearly and completely described. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0020] Please refer to Figures 1-4 , an intelligent communication manhole security device, including a straight pipe 1, the outer wall of the straight pipe 1 is rotatably connected with a top cover 2, an installation groove 5 is opened on the outer wall of the top cover 2, a base 3 is arranged on the inner wall of the installation groove 5, a main body 4 is fixedly assembled on the outer wall of the base 3, a chute 6 is opened on the outer wall of the base 3, a card hole 10 is opened on the inner wall of the chute 6, a limiting rod 11 is fixedly assembled on the inner wall of the card hole 10, a snap spring 13 is sleeved on the outer wall of the limiting rod 11, a retaining pin 12 is slidably connected to the outer wall of the limiting rod 11, a movable strip 14 is fixedly assembled on the outer wall of the retaining pin 12, a steel wire rope 9 is fixedly assembled on the outer wall of the movable strip 14, a winding wheel 7 and a rotating wheel 8 are rotatably connected to the outer wall of the base 3, a first winding groove 15 and a second winding groove 16 are respectively opened on the outer wall of the winding wheel 7, and a handle 17 is fixedly assembled on the outer wall of the base 3.

[0021] In the above structure, through the structures of the base 3, the main body 4, the retaining pin 12, and the limiting rod 11, during the use of the security device, the movable strip 14 slides along the inner wall of the chute 6, so that the retaining pin 12 moves, and thus the retaining pin 12 contracts to enable the base 3 to be placed into the installation groove 5. Then, the elastic force of the snap spring 13 is used to push the retaining pin 12 into the card hole 10, thereby achieving the effect of quickly installing the base 3 and the main body 4 and improving the installation efficiency of the installer for the security device.

[0022] In a preferred implementation manner: the diameter and shape of the card hole 10 are both adapted to the diameter and shape of the retaining pin 12, one end of the snap spring 13 abuts against the inner wall of the chute 6, and the other end of the snap spring 13 abuts against the outer wall of the retaining pin 12.

[0023] In the above structure, through the structures of the card hole 10, the retaining pin 12, and the snap spring 13, when the length of the steel wire rope 9 becomes shorter when the winding wheel 7 rotates, the steel wire rope 9 pulls the movable strip 14, so that the retaining pin 12 slides along the inner wall of the chute 6, thereby ensuring that both retaining pins 12 can be disengaged from the card hole 10 when the user rotates the winding wheel 7, and thus achieving the effect of quickly and labor-saving disassembly and assembly of the base 3.

[0024] In a preferred embodiment: the number of steel wire ropes 9 is two. One end of a steel wire rope 9 away from the movable bar 14 is fixedly assembled with the inner wall of the first winding groove 15, and one end of the other steel wire rope 9 away from the movable bar 14 is fixedly assembled with the inner wall of the second winding groove 16.

[0025] In the above structure, through the structure of the steel wire ropes 9 and the second winding groove 16 provided, the two steel wire ropes 9 are respectively located in different moving spaces. When the installer rotates the winding wheel 7, the winding wheel 7 drives the two steel wire ropes 9 to wind simultaneously, achieving the effect that the two pins 12 move synchronously, thereby ensuring that both sides of the base 3 can be fixed during the installation process, and further improving the stability of the base 3 after installation.

[0026] In a preferred embodiment: the base 3 is fixedly connected to the top cover 2 through the cooperation of the pins 12 and the pin holes 10, and the pins 12 are made of galvanized iron metal.

[0027] In the above structure, the galvanized iron metal has the characteristics of hardness and wear resistance, which can effectively reduce the wear degree of the pins 12 during the moving process. At the same time, its hardness characteristic can also ensure the fixing effect of the pins 12 on the base 3, and the galvanized iron metal also has the characteristic of low cost, reducing the production cost of this security equipment.

[0028] In a preferred embodiment: the inner wall of the chute 6 is slidably connected to the outer wall of the movable bar 14, and the outer wall of the steel wire rope 9 is rollingly connected to the middle of the rotating wheel 8.

[0029] In the above structure, through the structure of the chute 6 provided, the chute 6 can facilitate the installer to install the limiting rod 11, and the limiting rod 11 can limit the pin 12, ensuring that the pin 12 can only move horizontally when the steel wire rope 9 generates tension, improving the stability of the pin 12 during the moving process. At the same time, the chute 6 can also provide a moving space for the movement of the movable bar 14, ensuring that the pin 12 can be received into the base 3, avoiding interference caused by the pin 12 when the base 3 is connected to the installation groove 5, and further ensuring that the installer can achieve an effective installation operation.

[0030] In a preferred embodiment: the outer wall of the winding wheel 7 is fixedly assembled with stress plates. The number of stress plates is two, and the two stress plates are evenly distributed along the outer wall of the winding wheel 7.

[0031] In the above structure, through the stress plates provided, the user can respectively touch one stress plate with two fingers, and then rotate the fingertips to make the winding wheel 7 wind the steel wire rope 9, thereby achieving the effect of winding the steel wire rope 9 easily and labor - savingly, facilitating the operation of the installer, and further improving the practicability of this security equipment.

[0032] Working principle: First, the installer needs to rotate the top cover 2 so that the top cover 2 is perpendicular to the straight pipe 1. Then pick up the base 3 and touch one force-bearing plate with each of two fingers. Subsequently, rotate the fingertips so that both wire ropes 9 are wound around the winding wheel 7 as the center. At this time, the wire rope 9 will pull the wire rope 9, so that both pins 12 move into the interior of the base 3. At this time, the user can hold the handle 17 with one hand and continue to pinch the winding wheel 7 with the other hand. Then align the base 3 with the installation groove 5, and then push the base 3 into the installation groove 5. Then release the winding wheel 7. At this time, under the elastic action of the snap spring 13, the winding wheel 7 automatically reverses, releasing the wire rope 9, and the movable strip 14 will reset along the inner wall of the chute 6 so that the pin 12 is inserted into the inner wall of the card hole 10, achieving the effect of quickly fixing the base 3.

[0033] Although the embodiments of the present invention have been shown and described, for those of ordinary skill in the art, it can be understood that various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principle and spirit of the present invention. The scope of the present invention is defined by the appended claims and their equivalents.
