Description

Technical Field

[0001] The utility model relates to the field of cable bridges, in particular to a cable bridge which is convenient for fixing wires. Background Art

[0002] At present, a Chinese utility model with the announcement number CN212114650U discloses a trough-type cable tray structure, which relates to the technical field of cable trays, including a cable support arm, the cable support arm includes two oppositely arranged first cable baffles and second cable baffles, a cable support plate fixed on the bottom of the first cable baffle and the second cable baffle; a cavity, the cavity is opened inside the first cable baffle, a side of the first cable baffle is opened with a channel, and the channel and the cavity are connected; a rotating rod is rotatably connected to the inner side of the cavity, and a partition cloth-like object is wound on the rotating rod, and the partition cloth-like object is used to separate the cables inside the cable support arm from top to bottom. The partition cloth-like object provided by the utility model can separate the cables in the support arm from top to bottom, so that more cables are no longer piled up together, and the cables in the support arm are divided into two parts separated from each other, which effectively improves the ventilation of the space where the cables are located. In addition, the partition cloth-like object can be conveniently taken out and fixed in conjunction with the traction plate and the fixed trough plate, and the fixing process is also relatively simple.

[0003] Although the existing cable tray can improve the ventilation effect inside the tray through the air holes, there are still other problems during use, such as poor dust prevention effect. When the outside air enters the interior of the tray through the air holes, dust will enter together. After entering, the dust will fall down and adhere to the surface of the cable, which will have a certain impact on the heat dissipation effect of the cable. In addition, the cable cannot be limited. When the rear end of the cable is accidentally pulled by a person after being placed, the cable in the tray will be displaced, which may easily cause the connection at the other end of the cable to loosen and fall off, and the practicality is poor. In order to solve the above-mentioned problems, we propose a cable tray that is easy to fix the wires. Utility Model Content

[0004] The utility model aims to provide a cable bridge which is convenient for fixing wires, solves the problem that the existing bridge has good ventilation and dustproof effects and can facilitate the positioning of cables and wires.

[0006] The above technical solution can achieve good ventilation and dust prevention effects, the overall stability and reliability, and it is also convenient to clean. At the same time, it is easy to limit the cable conductors, the operation is simple and labor-saving, and the cable can be prevented from shifting due to accidental pulling, and it is highly practical.

[0007] The utility model is further configured as follows: a threaded rod is welded at the bottom of the filter plate, the other end of the threaded rod penetrates and extends to the bottom of the supporting plate, and a nut is threadedly connected to the surface of the threaded rod.

[0008] By adopting the above technical solution, the filter plate can be fixed by setting the threaded rod and the nut, so as to prevent the filter plate from shifting when the bridge frame shakes.

[0009] The utility model is further configured as follows: a handle is installed on the top of the filter plate.

[0010] By adopting the above technical solution and providing the handle, it is convenient for personnel to pull the filter plate upwards out of the supporting plate.

[0011] The utility model is further configured as follows: a limiting rod is symmetrically welded on the top of the limiting seat, and the other end of the limiting rod penetrates and extends to the inside of the fixing frame.

[0012] By adopting the above technical solution, the limiting seat can be limited by setting the limiting rod to prevent the limiting seat from tilting when moving up and down.

[0013] The utility model is further configured as follows: a pull rod is welded on the surface of the fixing rod, and a sliding groove is opened on the front side of the fixing frame.

[0014] By adopting the above technical solution, through the arrangement of the pull rod and the sliding groove, it is convenient for personnel to pull the limit seat upwards.

[0015] The utility model is further configured as follows: the support plate and the cover plate are both made of stainless steel.

[0016] By adopting the above technical solution, the support plate and the cover plate have the characteristics of high strength, low density and excellent corrosion resistance.

[0017] The utility model is further configured as follows: the fixing spring is made of carbon spring steel.

[0018] By adopting the above technical solution, the fixed spring has the characteristics of excellent mechanical properties, good anti-elasticity, low temperature resistance and corrosion resistance.

[0019] The utility model is further configured as follows: a rubber pad is installed inside the limit seat.

[0020] By adopting the above technical solution, the cable can be protected by the provision of the rubber pad, so as to prevent the limit seat from scratching the surface of the cable when pressing.

[0021] In summary, the utility model has the following beneficial effects:

[0022] 1. The utility model places the cover plate on the support plate first, and then lifts the filter plate by holding the handle after the cover plate is placed. After lifting the filter plate, it is placed in the support plate through the through slot. When the filter plate falls to the bottom, the bottom end of the threaded rod will pass downward, and finally the nut is turned onto the threaded rod and tightened. Good ventilation and dustproof effects can be achieved, the overall stability is firm, and it is also more convenient to clean.

[0023] 2. The utility model allows the user to grasp the pull rod and pull it upwards. When the pull rod is pulled upwards, it will drive the limit seat to move upwards through the fixed lower part of the fixed rod. When the limit seat moves upwards, it will compress the fixed spring to make it enter a contracted state. When the pull rod is pulled up to the bottom, the cable conductor at the rear will be pulled out, and then the cable will be placed under the limit seat and the pull rod will be released. After the pull rod is released and reset, it will clamp the cable, which can facilitate the limitation of the cable conductor. The operation is simple and labor-saving, and the cable can be prevented from shifting due to accidental pulling. The utility model is highly practical. BRIEF DESCRIPTION OF THE DRAWINGS
