Obviously, the embodiments described below are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0025] In the description of the present invention, it should be understood that the terms "upper", "lower", "top", "bottom", "inside", "outside" and the like indicate positions or positional relationships based on the positions or positional relationships shown in the drawings, and are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation of the present invention. It should be noted that when a component is considered to be "connected" to another component, it may be directly connected to the other component or there may be a centrally arranged component at the same time.

[0026] The technical solution of the present invention is further described below with reference to the accompanying drawings and through specific implementation methods.

[0027] Embodiment 1: See also Figure 1-7 A cable trench prefabricated member for cable installation in this embodiment includes a trench member 1, a mounting plate 3 is arranged on the side wall of the trench member 1, a mounting frame 2 is arranged between the two mounting plates 3, and the mounting frame 2 is used to support the cable; a plurality of mounting grooves 4 of equal length are provided on the side of the mounting plate 3 facing the mounting frame 2 along the height direction of the trench member 1 at equal intervals, and a plurality of plug holes 8 of equal height to the mounting plate 3 are provided on the mounting plate 3 corresponding to the mounting grooves 4 along the length direction of the trench member 1 at equal intervals, and the plug holes 8 are communicated with the mounting grooves 4; a connecting block 7 is provided on the side of the mounting frame 2 corresponding to the mounting groove 4, the connecting block 7 is arranged in the mounting groove 4, a connecting hole 71 is provided in the connecting block 7 corresponding to the plug hole 8, a plug rod 5 is inserted in the plug hole 8, and the plug rod 5 passes through the connecting hole 71.

[0028] When in use, before the cable needs to be installed, the connecting block 7 on the mounting frame 2 is first placed in the mounting groove 4 corresponding to the mounting groove 4, and then the mounting frame 2 is pushed to move the connecting block 7 in the mounting groove 4. After the connecting block 7 is moved until the connecting hole 71 is aligned with the plug hole 8, the plug rod 5 is inserted along the plug hole 8, and the plug rod 5 will pass through the plug hole 8 and the connecting hole 71, thereby fixing the connecting block 7 in the mounting groove 4. With the fixing of the connecting block 7, the mounting frame 2 for supporting the cable can also be installed in the groove member 1, and with the previous mounting frame 2 installed in the groove member 1, another mounting frame 2 can be installed in the same mounting groove 4 in the above manner. By limiting the installation positions of the two mounting frames 2 through the mounting groove 4, the front and rear mounting frames 2 installed in the groove member 1 can be on the same horizontal line, so that the subsequent cables are subjected to more uniform force during installation, thereby improving the service life and stability of the installed cables.

[0029] Embodiment 2: Basic content embodiment 1, the difference is: See also Figure 1-3 In this embodiment, the height of the connecting block 7 is equal to the height of the inner cavity of the mounting groove 4, the connecting block 7 moves linearly along its length direction in the mounting groove 4, the inner diameter of the jack 8 is equal to that of the connecting hole 71, the inner diameter of the jack 8 is matched with the outer diameter of the insertion rod 5, the height of the insertion rod 5 is equal to the height of the mounting plate 3, and the height of the mounting plate 3 is equal to the height of the inner cavity of the groove member 1.

[0030] During application, in the process of installing cables of different specifications in the groove member 1, the distance between the upper and lower mounting frames 2 can be adjusted conveniently and quickly through the provision of a plurality of mounting grooves 4, so that one of the mounting frames 2 can adapt to cables of different specifications on the adjacent mounting frames 2, thereby avoiding the limitation caused by the inability to adjust the distance between two upper and lower adjacent mounting frames 2, which leads to the inability to install cables of different specifications. At the same time, during the installation process of the mounting frame 2, the matching inner diameter of the jack 8, the connecting hole 71 and the outer diameter of the plug rod 5 can improve the stability of the connecting block 7 installed in the mounting groove 4, thereby improving the stability of the mounting frame 2, and the plug rod 5 having the same height as the mounting plate 3 can adapt to the connecting blocks 7 installed in different mounting grooves 4, so as to facilitate the installation of cables of different specifications.

[0031] Furthermore, a groove 31 is provided on the top surface of the mounting plate 3 corresponding to the socket 8, the groove 31 is connected to the socket 8, the inner diameter of the groove 31 is larger than the inner diameter of the socket 8, and the plug rod 5 is located in the groove 31; when the groove member 1 or the cable needs to be repaired, the groove 31 corresponding to the plug rod 5 can facilitate the removal of the plug rod 5 in the socket 8, so as to facilitate the separation of the mounting frame 2 from the groove member 1, and at this time the groove member 1 or the cable can be repaired.

[0032] It can be known that, through the design of the structures such as the jack 8, the plug rod 5, and the connecting block 7, the convenience of installing and disassembling the mounting frame 2 is improved, and the construction difficulty is reduced.

[0033] Embodiment 3: Basic content embodiment 1, the difference is: See also Figure 4-7 The mounting frame 2 in this embodiment is a U-shaped seat, and a positioning unit 6 for positioning the cable is provided on the mounting frame 2. The positioning unit 6 includes a plurality of partitions 61 and a clamping plate 62. The plurality of partitions 61 are arranged in the mounting frame 2, and the plurality of partitions 61 are evenly spaced along the length direction of the mounting frame 2. A positioning area 21 is formed between two adjacent partitions 61. A top plate 63 is hinged on the mounting frame 2 through a hinge shaft. A plurality of clamping plates 62 are abutted in groups of two, and are arranged on the top plate 63 corresponding to the positioning area 21. The top plate 63 is connected to the mounting frame 2 through a clamping unit. An opening 64 is opened on the top plate 63 corresponding to the positioning area 21. The two abutting clamping plates 62 are slidably connected in the opening 64, and the opposite side of the two abutting clamping plates 62 and the part near the bottom end thereof are set as an inclined surface 65. The clamping plate 62 is elastically connected to the inner side wall of the opening 64, and the bottom end of the clamping plate 62 abuts on the inner bottom wall of the mounting frame 2.

[0034] In application, after the mounting frame 2 is installed in the groove member 1, the cable can be placed on the mounting frame 2. During installation, the top plate 63 is rotated to open the positioning area 21, and then the cable is placed in the positioning area 21. After the cable is placed, the top plate 63 is rotated to make the top plate 63 abut against the partition plate 61. When the top plate 63 moves, the clamping plate 62 will also move synchronously and gradually move into the positioning area 21. When the clamping plate 62 enters the positioning area 21, the inclined surface 65 on the clamping plate 62 will contact the surface of the cable. As the top plate 63 continues to move, the top plate 63 will squeeze the clamping plate 62 through the cable, so that the two clamping plates 62 entering the positioning area 21 move toward the corresponding partition 61. After the top plate 63 rotates to abut against the top surface of the partition 61, the elastic force generated by the elastically connected clamping plate 62 can clamp the cable in the positioning area 21 and position the cable in the positioning area 21. At the same time, through the clamping plate 62 elastically set on the top plate 63, cables of different specifications can also be positioned, thereby improving adaptability.

[0035] It can be known that, through the positioning unit 6, in the process of the flipping clamp 62 abutting against the partition 61, the clamp 62 can complete the positioning of the cable, so that the cable can be positioned in the positioning area 21 between the two partitions 61 quickly, thereby improving the positioning efficiency of the cable.

[0036] It should be noted that after the flip clamping plate 62 abuts against the partition plate 61 , the top plate 63 can be fixed on the mounting frame 2 by a clamping unit.

[0037] Furthermore, a connecting rod 67 is provided in the opening 64 along its length direction, and the clamping plate 62 is sleeved on the connecting rod 67. The clamping plate 62 and the inner wall of the opening 64 are connected by a spring 66. Through the spring 66 and the connecting rod 67, the clamping plate 62 can be more stable when moving in the opening 64, and the clamping plate 62 can clamp and position the cable under the action of the elastic force of the spring 66.

[0038] Furthermore, the bottom surface of the clamping plate 62 is set to be an arc surface; when the top plate 63 squeezes and positions the cable through the clamping plate 62, the arc surface can avoid damage to the surface of the cable, thereby improving the protection effect.

[0039] Embodiment 4: Basic content embodiment 1, the difference is: See also Figure 8 In this embodiment, the top surface of the groove member 1 is clamped with a cover plate 9, and the groove member 1 includes two half-pieces 11, which are abutted against each other. A connecting piece 12 is fixed at the abutting point of one of the half-pieces 11, and a slot 13 is opened at the abutting point of the other half-piece 11 corresponding to the connecting piece 12. The connecting piece 12 is inserted into the slot 13, and a screw is vertically arranged on the connecting piece 12, and the screw is threadedly connected to the half-piece 11 corresponding to the slot 13.

[0040] When in use, by splicing the two half pieces 11, the connecting piece 12 can be moved into the slot 13, and then the two half pieces 11 are assembled into the groove piece 1 by screws. After the assembly is completed, the mounting frame 2 and the cable can be gradually installed. Finally, after the cable is installed, the cover plate 9 is snapped onto the groove piece 1. At this time, the entire installation of the cable is completed; the groove piece 1 is spliced ​​by two half pieces 11. The spliced ​​groove piece 1 is easy to transport and carry. In actual use, it also has the advantages of high flexibility and easy and quick installation. The spliced ​​groove piece 1 is also convenient for subsequent repair and maintenance work.

[0041] Embodiment 5: Basic content embodiment 1, the difference is: See also Figure 1 A cable trench for cable installation in this embodiment includes a plurality of trench members 1 as in the above-mentioned embodiment 1, and each trench member 1 is spliced ​​in sequence along its length direction.
