Detailed ways

In order to further understand the content, characteristics and effects of the present invention, the following examples are given and described in detail below with reference to the accompanying drawings.

Please refer to FIGS. 1 to 8 at the same time. The anti-theft cable trench cover and cable trench structure according to the embodiment of the present invention will be described in detail below in conjunction with the accompanying drawings.

As shown in Figure 1, the anti-theft cable trench cover and cable trench structure include a trench cover body 1 and a plug-in fixing rod 2. The characteristic is that the trench cover body 1 is provided with a first through-slot 3 and a third through-slot 3. Two through grooves 4, two first through grooves 3 and four second through grooves 4 are provided respectively at the corners of the trench cover plate body 1;

The plug-in fixing rod 2 is located inside the second through-slot 4 and extends toward the inside of the second through-slot 4 to the outside of the ditch cover. The two sides of the plug-in fixation rod 2 are elastically connected with snap plates 5 .

In this application, in order to improve the anti-theft effect and facilitate the opening of the trench cover, the above structure is provided. The specific implementation is as follows:

The cable trench structure in this application is used in conjunction with the aforementioned trench cover body 1 and includes a cable bracket 15 fixed inside the cable trench. A plug-in slot 16 is provided at the top of the cable bracket 15 for inserting the fixing rod 2. After the plug-in fixing rod 2 is inserted, the clamping plates 5 on both sides of the plug-in fixing rod 2 come into contact with the inner wall of the plug-in slot 16 away from the plug-in fixing rod 2 .

When the cable trench structure is poured, the cable bracket 15 with the plug-in slot 16 from the top is poured directly. The size of the plug-in slot 16 is slightly larger than the size of the plug-in fixing rod 2. Then during installation, the cable bracket 15 can be installed according to the shape of the trench cover body 1. The width adjusts the placement distance of the cable brackets 15. At the same time, the width of the trench cover body 1 can be customized according to the placement distance of the cable brackets 15. During installation, directly insert the plug-in fixing rod 2 into the plug-in slot 16.

The plug-in fixing rods 2 are provided at the four corners of the ditch cover body 1, as shown in Figure 1, and the second through-slots 4 are arranged corresponding to the positions of the plug-in fixing rods 2.

Specifically, the plug-in fixing rod 2 is hingedly connected to the snap-in plate 5 near the bottom end. Two snap-in plates 5 are provided symmetrically about the middle part of the plug-in fixation rod 2. There is a fixed connection between the snap-in plate 5 and the plug-in fixation rod 2. The spring 6 and the clamping plate 5 can rotate, so under the resistance of the connecting spring 6, the clamping plate 5 can be automatically moved away from the plug-in fixing rod 2 and against the inner wall of the plug-in slot 16, and the top of the plug-in fixing rod 2 is fixed. There is a driving part for driving the plug-in fixing rod 2 to lift and open the trench cover.

The driving part includes an elastic steel splint 7 hinged on the inside of the two clamping plates 5. The upper end of the elastic steel splint 7 is higher than the plug-in fixed rod 2, and the part above the plug-in fixed rod 2 is arc-shaped. The elastic steel splint 7 There are connecting plates 8 rotatably connected to both sides, and the end of the connecting plate 8 away from the elastic steel splint 7 is hingedly connected inside the trench cover plate body 1.

The elastic steel splint 7 can slide along the height direction of the plug-in fixed rod 2. When the elastic steel splint 7 is pulled upward, since both ends of the elastic steel splint 7 are hingedly connected to the connecting plate 8, the other end of the connecting plate 8 is connected to the trench cover plate. The connection of the body 1 is also a rotational connection, so the elastic steel splint 7 can move. At the same time, the bottom of the elastic steel splint 7 is hingedly connected to the sides of the two clamping plates 5. With the movement of the elastic steel splint 7, the two clamping plates 7 can be driven. The clamping plate 5 rotates, thereby releasing the conflicting effect between the clamping plate 5 and the plug-in slot 16, and then the trench cover body 1 can be opened.

At the same time, when not in use, a loose-leaf baffle 9 is hingedly connected inside the second through slot 4. One side of the loose-leaf baffle 9 is provided with a fixed block 10 fixed on the top of the ditch cover body 1. The loose-leaf baffle 9 and the fixed block 10 screws are fixed, and the loose-leaf baffle 9 and the fixed block 10 are locked by anti-theft screws. The anti-theft screws can be of any type purchased in the existing market.

This embodiment also includes a cover hook set for opening the ditch cover body 1. As shown in Figures 7 and 8, the cover hook set includes two independent cover hooks 11. The top of each cover hook 11 is A connecting ring 12 is fixed, and a chain 13 is connected between the two connecting rings 12. A rubber sleeve 14 is set on the outside of the chain 13. An oblique hook groove 17 is provided on the inside of the cover trench 11. When the trench cover body 1 is opened, By holding the rubber sleeve 14 on the cover hook set, the two cover hooks 11 can be placed inside the first through groove 3 and the second through groove 4 respectively, and the elastic steel splint 7 and the trench cover plate body can be pulled simultaneously 1. When the hook is pulled, it is clamped through the oblique hook groove 17, which is convenient for use. At the same time, it can be used alone to pull the elastic steel splint 7.

In this embodiment, the first through-slot 3 and the second through-slot 4 provided on the trench cover body 1 are both waist-shaped, so it is convenient to place the above-mentioned cover hook 11 .

In the present invention, the trench cover is directly used in combination with the cable trench, and the plug-in fixing rod and the anti-theft screw are used for double anti-theft, so that the anti-theft effect is greatly improved.

Although the embodiments of the present invention have been shown and described, those of ordinary skill in the art will understand that various changes, modifications, and substitutions can be made to these embodiments without departing from the principles and spirit of the invention. and modifications, the scope of the invention is defined by the appended claims and their equivalents.
