[0019] 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.

[0020] like Figure 1-Figure 2 As shown, a telescopic steel grating cable trench cover comprises a supporting frame 1, a fixed cover 2 is installed on the upper end of the supporting frame 1, and ventilation holes 201 are opened on both sides of the upper end surface of the fixed cover 2. The advantage of this arrangement is that, through the arrangement of the fixed cover 2, the fixed grille 101 can be blocked and protected to prevent dust and debris from entering the interior of the fixed grille 101. Through the arrangement of the ventilation holes 201, the fixed grille 101 can be protected and the entry of larger debris into the cable trench can be reduced, while the cable lines inside the cable trench can be cooled.

[0021] Furthermore, slide grooves 203 are provided on both sides of the inner wall of the front end of the support frame 1, and a telescopic cover 202 is slidably installed inside the slide groove 203. The telescopic cover 202 is arranged below the fixed cover 2. The advantage of this arrangement is that, through the arrangement of the telescopic cover 202, when the heat is dissipated to the cable, the telescopic cover 202 can be slid to expose the fixed grille 101 to dissipate heat to the internal cable line. During normal use, the telescopic cover 202 is extended to protect the cable, and it is also convenient to observe the condition of the cable.

[0022] Furthermore, a groove 204 is provided on the upper surface of the telescopic cover 202, and an insert block 205 is provided at the front end of the telescopic cover 202. The advantage of this arrangement is that the telescopic cover 202 can be limited and fixed by the insert block 205.

[0023] Furthermore, a slot 206 is provided on the inner wall of the front support frame 1 of the plug block 205, and the slot 206 and the plug block 205 are plug-in connected. Through the setting of the slot 206, the easily sliding telescopic cover 202 can be limited to prevent it from loosening and opening, causing debris to enter the interior of the cable trench through the fixed grille 101.

[0024] Furthermore, a fixed grille 101 is arranged inside the support frame 1, and the material of the fixed grille 101 is 404 stainless steel. The advantage of this arrangement is that the fixed grille 101 made of 404 stainless steel can effectively improve the protection capability of the fixed grille 101, thereby avoiding the risk of damage to the fixed grille 101 and personal injury due to stepping on or the like when the telescopic cover 202 is opened, if the fixed grille 101 is not strong enough.

[0025] like Figure 3 As shown, placement grooves 3 are provided on both side surfaces of the support frame 1, and rotating rods 302 are installed on the inner walls of the placement grooves 3. Through the setting of the rotating rods 302, the handle 301 can be assisted to rotate while limiting the handle 301, and the service life of the handle 301 can be improved, so that the handle 301 can be used to lift the support frame 1 at any time.

[0026] Furthermore, a torsion spring 303 is provided on the surface of the rotating rod 302, and the torsion spring 303 is installed in the middle of the surface of the rotating rod 302. The advantage of this arrangement is that the handle 301 can be reset after installation through the arrangement of the torsion spring 303.

[0027] Furthermore, a handle 301 is installed on the surface of the rotating rod 302, and the handle 301 and the rotating rod 302 are rotatably connected. The advantage of this arrangement is that the stacked support frames 1 can be easily taken out through the arrangement of the handle 301, and at the same time, the installation is more convenient and quick, thereby speeding up the installation of the support frames 1.

[0028] Working principle: When using the telescopic steel grating cable trench cover, first, hold the handle 301 and pull the support frame 1 upwards. After lifting the support frame 1, after moving it to the position of the cable trench, place the support frame 1 above the cable trench and release the handle 301. The torsion spring 303 rotates and drives the handle 301 along the rotating rod 302 to enter the placement slot 3 of the support frame 1 to complete the installation. When it is necessary to dissipate heat for the cables inside the cable trench, pull the pull slot 204 backward to drive the plug 205 at the front end of the telescopic cover 202 out of the restriction of the slot 206, and then slide the telescopic cover 202 slowly backward along the slide slot 203 until the fixed grille 101 leaks out, thereby increasing the heat dissipation space of the cables installed inside the cable trench and observing the condition inside the cables. If the cables are damaged, they can be inspected and maintained in time. This is the working principle of the telescopic steel grating cable trench cover.
