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.

[0025] See also Figures 1 to 8The utility model provides a cable bridge that is convenient for fixing cables, including a trough body 1 and a cover plate 2 connected to the top of the trough body 1. Two support seats 5 are connected in the trough body 1, and the two support seats 5 are relatively distributed. A plurality of V-shaped plates 6 are fixed on the top of the support seat 5, and a movable pressing plate 7 is connected to the support seat 5, and the pressing plate 7 matches the corresponding V-shaped plate 6. A sliding block 18 is connected to the bottom of the pressing plate 7, and a guide groove 22 is provided on the top of the sliding block 18. The guide groove 22 is used to guide the pressing plate 7 to improve the stability of the movement of the pressing plate 7.

The support seat 5 is connected to a driving mechanism for driving the plurality of sliding blocks 18 to move synchronously, and the support seat 5 is connected to a positioning mechanism for positioning the cover plate 2, and the driving mechanism is connected to the positioning mechanism.

[0026] When the cable is laid, the rotating handle 9 drives the driving tooth 14 to rotate, and synchronously drives the two driven teeth 12 to rotate. The driven teeth 12 drive the corresponding rotating columns 19 to rotate, so that the multiple pressing plates 7 move synchronously toward the corresponding V-shaped plates 6. Figure 4 The middle X points to the direction where the guide block 21 slides in the slide slot 22 and the spring 1 23 is compressed, thereby achieving synchronous compression and fixation of multiple cables. The installation efficiency is high and the cable can be locked with cables of different diameters, which has strong applicability.

[0027] A guide block 21 is connected to the bottom of the pressure plate 7, and the guide block 21 is slidably connected to the guide groove 22. The end of the spring 23 is connected to the guide block 21. When facing cables of different directnesses, the compression displacement of the spring 23 corresponding to the cable with a larger diameter is greater than that of the cable with a smaller diameter. The difference in compression displacement is limited, and the cable with a smaller diameter can achieve the purpose of locking.

[0028] A guide post 24 is connected in the guide groove 22 . The guide post 24 passes through the guide block 21 . A spring 23 is sleeved on the guide post 24 .

[0029] The driving mechanism includes two rotating columns 19, two driven teeth 12, a transmission chain 13, a driving tooth 14, a rotating handle 9, and a locking head 10. The rotating column 19 is threadedly connected to a plurality of sliding blocks 18. The internal threads of the plurality of sliding blocks 18 have the same direction. The end of the rotating column 19 is connected to the driven teeth 12. The driven teeth 12 and the driving teeth 14 are meshed and connected through the transmission chain 13. The rotating handle 9 is used to drive the driving teeth 14 to rotate, and the locking head 10 is used to lock the rotating handle 9. When locking the cable, the rotating handle 9 is driven to drive the driving teeth 14 to rotate. The driving teeth 14 drive the two driven teeth 12 to rotate through the transmission chain 13. The transmission efficiency is high, and the rotation directions of the two driven teeth 12 are consistent. The driven teeth 12 drive the corresponding rotating column 19 to rotate, driving the sliding block 18 to move forward, that is, the pressing plate 7 moves toward the direction of the V-shaped plate 6, which is convenient for pressing the cable. Then, the rotary locking head 10 is connected to the limiting groove on the side of the connection box 8 to position the rotary handle 9 to prevent it from loosening and affecting the stability of the cable and the cover plate 2.

[0030] The side of the trough body 1 is connected to a connection box 8, and the driven gear 12, the transmission chain 13, and the driving gear 14 are located in the connection box 8. The connection box 8 has a protective effect on the driven gear 12, the transmission chain 13, and the driving gear 14, reducing the invasion of dust and impurities that affect the transmission effect. The driving gear 14 is rotatably connected to the connection box 8, and the driving gear 14 is connected to a rotating shaft, the end of the rotating shaft is fixedly connected to the rotating handle 9, and the locking head 10 is threadedly connected to the rotating handle 9. The side of the connection box 8 is provided with a limit groove matching the end of the locking head 10, and the locking head 10 is a common bolt.

[0031] The positioning mechanism includes two moving plates 4, two sliding blocks 17, two pressing blocks 16, two springs 25, and two vertical slots 26. The sliding block 17 is connected to the support seat 5, and the top of the sliding block 17 is connected to the moving plate 4. The vertical slot 26 is set on the side of the moving plate 4. The pressing block 16 is slidably connected to the vertical slot 26. The two ends of the spring 25 are connected to the pressing block 16 and the moving plate 4. The rotating column 19 is used to drive the two sliding blocks 17 to move closer to or away from each other. The internal threads of the two sliding blocks 17 are in opposite directions. The rotation of the rotating column 19 can drive the two sliding blocks 17 to move away from each other, so that the two moving plates 4 move away from each other. The pressing block 16 is pressed against the inclined slot 15 of the limiting plate 3, and the spring 25 is compressed. The pressing block 16 has a downward force on the limiting plate 3, so that the cover plate 2 is pressed against the slot body 1, thereby improving the tightness of the connection between the two and achieving a good installation purpose, replacing the traditional multiple bolt locking, and the operation is flexible and convenient.

[0032] The inner side of the cover plate 2 is connected to a limiting plate 3 , and the side surface of the limiting plate 3 is provided with an inclined groove 15 matching with the pressing block 16 .

[0033] A plurality of positioning grooves 11 are provided on the top of the trough body 1, and the positioning grooves 11 match the protrusions connected to the bottom of the cover plate 2. When the cover plate 2 is installed, the protrusions are inserted into the corresponding positioning grooves 11 to achieve preliminary positioning of the cover plate 2. At this time, the pressing block 16 is aligned with the corresponding inclined groove 15, which is convenient for docking with the inclined groove 15.

[0034] A slide groove 20 is provided in the support seat 5, and the sliding block 17 and the sliding block 2 18 are slidably connected to the slide groove 20, so that the sliding block 17 and the sliding block 2 18 can move stably.

[0035] Working principle: After the cable is laid, the cover plate 2 is connected to the top of the trough body 1, and the rotating handle 9 is rotated to drive the driving tooth 14 to rotate. The driving tooth 14 drives the two driven teeth 12 to rotate synchronously through the transmission chain 13, and the driven teeth 12 drive the rotation of the corresponding rotating column 19. The rotating column 19 drives multiple sliding blocks 18 to move forward, so that the pressure plate 7 moves toward the corresponding V-shaped plate 6. When the rotating handle 9 rotates a certain angle, the pressure plate 7 is pressed against the cable. At this time, the spring 1 23 is in a compressed state, realizing the synchronous compression and fixation of multiple cables, with high installation efficiency and applicable to the locking of cables of different diameters. At the same time, the rotating column 19 drives the two moving plates 4 away from each other, and the moving plate 4 drives the pressing block 16 to move in the direction of the corresponding inclined slot 15. The pressing block 16 is pressed against the inclined slot 15 of the limit plate 3, and the spring 25 is compressed. The pressing block 16 exerts a downward force on the limit plate 3, so that the cover plate 2 is pressed against the tank body 1, and the tightness of the connection between the two is improved to achieve a good installation purpose, and then the locking head 10 is used to lock the rotating handle 9. When the inside of the tank body 1 needs to be repaired, the rotating locking head 10 is rotated to loosen the rotating handle 9, and then the rotating handle 9 is rotated to drive the driving tooth 14 to rotate, so that the two driven teeth 12 rotate synchronously, and the driven teeth 12 drive the corresponding rotating column 19 to rotate, so that multiple sliding blocks 2 18 move back synchronously, and the pressing plate 7 is gradually separated from the cable, so that multiple cables are loosened synchronously, and the two moving plates 4 are close to each other, so that the pressing block 16 is separated from the inclined slot 15, and the cover plate 2 is loosened, so that the cover plate 2 can be opened conveniently, and the inside of the tank body 1 can be inspected and repaired.
