[0021] 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.

[0022] Embodiment 1

[0023] See also Figure 1-5 As shown, a telescopically installed cable bridge comprises a first bridge body 1; a fixing mechanism is arranged on the side of the first bridge body 1, a telescopic mechanism is arranged on the inner side of the first bridge body 1, a positioning mechanism is arranged on the top side of the telescopic mechanism, and cylinders 8 are fixed at both ends of the side of the first bridge body 1.

[0024] The fixing mechanism includes a cylinder 8, a piston 9 is slidably mounted inside the cylinder 8, a fixing rod 10 is fixed to one side of the piston 9, and a piston rod 11 is fixed to the other side of the piston 9, one end of the piston rod 11 passes through the cylinder 8 and is fixed with a disc 12, and the piston rod 11 is slidably connected to the cylinder 8, and a pull rod 13 is fixed to one side of the disc 12, fixing grooves 7 are evenly opened on both sides of the second bridge body 4, through holes 2 are respectively opened at both ends of the side of the first bridge body 1, and the through holes 2 are located at one end of the inner side of the cylinder 8, the fixing rod 10 is inserted and installed in the through hole 2, and one end of the fixing rod 10 is buckled in the fixing groove 7;

[0025] During operation, when encountering the problem that the fixing screws need to be disassembled and installed before and after the cable bridge is extended or retracted, and the operation is rather cumbersome, through the structure of the fixing mechanism, the pull rod 13 is used to pull the disc 12, and the piston 9 is driven to move in the cylinder 8 with the cooperation of the piston rod 11, and the air in the cylinder 8 is compressed. At the same time, the piston 9 pulls the fixing rod 10 to pull it out of the fixing groove 7. At this time, the second bridge body 4 can slide and retract in the first bridge body 1. When it is extended or retracted to the appropriate length, the pull rod 13 is released. At this time, the compressed air in the cylinder 8, with the cooperation of the piston 9, pushes the fixing rod 10 to buckle in the fixing groove 7 to fix the cable bridge. The operation is simple and easy to use, and the telescopic length of the cable bridge can be changed at any time.

[0026] The telescopic mechanism comprises a first bridge frame body 1, a limiting groove 3 is provided inside the first bridge frame body 1, and a second bridge frame body 4 is slidably mounted inside the first bridge frame body 1 through the limiting groove 3;

[0027] During work, if the cable tray cannot be used due to length inconsistency, the cable tray can be adjusted to a suitable length as needed through the structure of the telescopic mechanism, and the first tray body 1 and the second tray body 4 can be removed separately, which is more convenient for storage and transportation.

[0028] The positioning mechanism comprises a second bridge frame body 4, the top and bottom sides of which are respectively fixed with sliders 5, the sliders 5 are slidably installed in the limiting grooves 3, and a scale groove 6 is provided on the top side of the second bridge frame body 4 at the middle position of the sliders 5;

[0029] During operation, when encountering the problem that the cable tray cannot be accurately extended and retracted to the required length, which causes the cable to be easily aged and damaged, the positioning mechanism is used to pull the first tray body 1 at one end to extend and retract the cable tray as a whole. At this time, the scale groove 6 on the top side of the second tray body 4 will be exposed to the external environment. At this time, the extension length of the cable tray can be known by observing the position of the scale groove 6, thereby improving the installation accuracy of the cable tray and extending the working life of the cable.

[0030] Embodiment 2

[0031] See also Figure 6 As shown, compared with Example 1, as another implementation mode of the utility model, rubber plugs 14 are provided on both sides of the second cable tray body 4, and the rubber plugs 14 are buckled in the fixing groove 7; during operation, when the cable tray is extended, dust is easily accumulated in the fixing groove 7 exposed to the external environment, resulting in loose fixation when the extension length of the cable tray is subsequently changed, thereby reducing its working life. Through the structure of the rubber plug 14, it can be buckled in the fixing groove 7 exposed to the external environment, so that dust will not accumulate inside, which is convenient for subsequent maintenance and use, and extends the working life of the cable tray.

[0032] Working principle: Cable trays can be used to lay communication cables, control cables, computer cables, etc. They have the function of shielding interference and preventing cable corrosion and damage. They can be divided into ladder-type, tray-type and trough-type structures, and are mainly installed on various buildings and pipe gallery brackets. The upper cover plate of the existing cable tray is fixed to the main body of the tray by fixing screws. When the telescopic length needs to be changed again, the fixing screws must be removed first, which is cumbersome to operate. In addition, when in use, the telescopic length accuracy of the cable tray is low, and it cannot be accurately telescoped to a fixed size. In order to solve this problem, a fixing mechanism is set up, and the pull rod 13 pulls the disc 12, and with the cooperation of the piston rod 11 The piston 9 is driven to move in the cylinder 8 to compress the air in the cylinder 8. At the same time, the piston 9 pulls the fixing rod 10 to pull it out of the fixing groove 7. At this time, the second bridge frame body 4 can slide and retract in the first bridge frame body 1 with the cooperation of the slider 5 and the limit groove 3. At this time, the telescopic length of the cable bridge can be known by observing the position of the scale groove 6. When it is retracted to the appropriate length, the pull rod 13 is released. At this time, the compressed air in the cylinder 8, with the cooperation of the piston 9, pushes the fixing rod 10 to buckle in the fixing groove 7 to fix the cable bridge, which solves the problem that the fixing screws need to be disassembled and installed before and after the cable bridge is extended and retracted, the operation is cumbersome and the accuracy of the telescopic length of the cable bridge is low.

[0033] The above shows and describes the basic principle, main features and advantages of the utility model. Those skilled in the art should understand that the utility model is not limited by the above embodiments, and the above embodiments and descriptions are only for explaining the principle of the utility model.
