[0019] The utility model is further described below in conjunction with the accompanying drawings:

[0020] Embodiment 1:

[0021] See also Figure 1-5In the present embodiment, a prefabricated cable trench with stable assembly includes a square frame 1 and a round opening 6. The round opening 6 is respectively processed on the upper and lower sides of the right side of the square frame 1. The inner wall of the square frame 1 is connected with an adjustment structure 2. The right side of the adjustment structure 2 is connected with a straight plate 4. The top of the straight plate 4 is connected with a control structure 3. The top of the control structure 3 is connected with multiple arc plates 5. The arc plates 5 are made of plastic material and can undergo a small range of elastic deformation, which is convenient for clamping the cable. The outer wall of the control structure 3 is plugged into the top opening of the straight plate 4.

[0022] The adjustment structure 2 includes a first screw rod 201 and a cylinder 202. The upper and lower sides of the first screw rod 201 are respectively fixedly connected to the upper and lower sides of the inner wall of the square frame 1. The outer wall of the first screw rod 201 is threadedly connected to the inner wall of the cylinder 202. The cylinder 202 is subjected to force and rotates up and down through the outer wall of the first screw rod 201. The outer wall of the cylinder 202 is rotatably connected to a curved plate 203. The cylinder 202 is subjected to force and rotates through the inner wall bearing of the curved plate 203. The right side of the curved plate 203 is fixedly connected to the left side of the straight plate 4. The outer wall of the curved plate 203 fits the inner wall of the square frame 1. The curved plate 203 is subjected to force and moves up and down on the inner wall of the square frame 1.

[0023] By holding the cylinder 202 in the adjustment structure 2 and rotating it up and down on the outer wall of the first screw rod 201, the rotating cylinder 202 moves the curved plate 203 up and down on the inner wall of the square frame 1, and the moving curved plate 203 moves the position of the straight plate 4 to achieve adjustment of the spacing between the plurality of straight plates 4. Since the cylinder 202 and the first screw rod 201 are threadedly connected, as long as the cylinder 202 is not rotated, the position of the straight plate 4 can be kept unchanged, thereby improving stability, improving the protection effect of the prefabricated cable trench, and ensuring the normal use of the prefabricated cable trench.

[0024] The control structure 3 includes a horizontal plate 301 and a second screw rod 302. The bottom of the horizontal plate 301 fits with the top of the straight plate 4. The left and right sides of the bottom of the horizontal plate 301 are respectively fixedly connected to the top of the second screw rod 302. The outer wall of the second screw rod 302 is threadedly connected with a ring 303. The ring 303 is subjected to force to rotate up and down through the outer wall of the second screw rod 302. The top of the horizontal plate 301 is fixedly connected to the bottom of multiple arc plates 5, and the outer wall of the second screw rod 302 is plugged into the top opening of the straight plate 4.

[0025] Working principle:

[0026] Prefabricated cable trench installation:

[0027] The left side of the square frame 1 is made to fit with the inner wall of the ditch, and then the bolt thread passes through the round opening 6 and is threadedly connected with the inner wall of the ditch to complete the installation of the prefabricated cable trench.

[0028] Prefabricated cable trench cable laying:

[0029] Hold the cylinder 202 and rotate it up and down on the outer wall of the first screw rod 201. The rotating cylinder 202 brings the curved plate 203 to move up and down on the inner wall of the square frame 1. The moving curved plate 203 brings the straight plate 4 to move its position, so as to adjust the spacing between the multiple straight plates 4. Since the cylinder 202 and the first screw rod 201 are threadedly connected, as long as the cylinder 202 is not rotated, the position of the straight plate 4 can be guaranteed to remain unchanged, thereby improving the assembly stability.

[0030] Next, select the corresponding arc plate 5, and insert the second screw rod 302 at the bottom of the horizontal plate 301 into the through hole at the top of the straight plate 4 until the bottom of the horizontal plate 301 fits with the top of the straight plate 4, and then the ring 303 is threadedly connected with the outer wall of the second screw rod 302 from bottom to top, so that the top of the ring 303 is tightly pressed against the bottom of the straight plate 4, and then the cable is gradually inserted into the arc plate 5.

[0031] Embodiment 2:

[0032] See also Figure 1-5 : In this embodiment, a prefabricated cable trench with stable assembly also includes a sheath 7, and the inner wall of the sheath 7 is fixedly connected to the right side of the straight plate 4.

[0033] Working principle:

[0034] When the prefabricated cable trench is used, a person needs to go down into the trench to lay cables. The sheath 7 wraps the outer wall of the straight plate 4 to prevent people from being scratched and injured by the straight plate 4 when walking. The sheath 7 realizes the protection function.

[0035] Although the present invention has been shown and described with reference to the preferred embodiments, it will be understood by those skilled in the art that various changes in form and details may be made therein within the scope of the claims.
