Description

Technical Field

[0001] The utility model relates to the field of bridge frames, in particular to a high-strength tray-type sealed junction bridge frame. Background Art

[0002] Cable trays are divided into trough-type cable trays, tray-type cable trays and ladder-type cable trays. Tray-type cable trays can be further divided into open-type trays and closed-type trays. The open-type trays have good ventilation and heat dissipation properties, but poor waterproof and dustproof effects. The closed-type trays have good dust and water resistance effects, but poor ventilation and heat dissipation effects. Both have certain limitations in use and poor practicality. At the same time, the current tray-type cable trays generally use bolt-type fixed installation between the tray and the cover plate, which takes a lot of time to install, is troublesome to install, and has low efficiency. In order to solve the problems mentioned in the above background, we propose a high-strength tray-type sealed junction cable tray. Utility Model Content

[0005] By adopting the above technical scheme, the utility model installs a cavity at the bottom of the support shell, and hygroscopic masterbatch is installed inside the cavity. When the negative pressure fan inside the exhaust seat on the top of the cover plate is started, the external airflow enters the support shell through the air inlet groove, and the hygroscopic masterbatch absorbs moisture and filters dust during the process, so as to ensure the dryness and cleanliness of the air, ensure the dustproof and waterproof effects, and improve the ventilation and heat dissipation effects inside the support shell. A groove body is opened on the cover plate, and a card block is installed inside the groove body. When the cover plate and the support shell need to be installed together, it is only necessary to insert the protrusion of the cover plate into the inside of the support shell, and insert the card block into the card slot of the support shell, without using bolts, thereby improving the speed and efficiency of installation.

[0006] The utility model is further configured as follows: the surface of the air extraction seat is symmetrically connected with an exhaust cavity.

[0007] The above technical solution is adopted to facilitate the discharge of gas inside the support shell.

[0008] The utility model is further configured as follows: an air inlet groove communicating with the cavity is opened at the bottom of the support shell.

[0009] The above technical solution facilitates the gas inside the cavity to enter the support shell.

[0010] The utility model is further configured as follows: a mounting seat bolted to an exhaust seat is symmetrically bolted on the surface of the negative pressure fan.

[0011] The negative pressure fan is fixed by adopting the above technical solution.

[0012] The utility model is further configured as follows: a sealing strip is symmetrically clamped between the cover plate and the supporting shell.

[0013] The above technical solution is adopted to seal the cover plate and the support shell.

[0014] The utility model is further configured as follows: a guide rod which is slidably connected to the clamping block is bolted inside the groove body.

[0015] The above technical solution is adopted to slide and limit the block.

[0016] The utility model is further configured as follows: a buckle seat is bolted on the top of the cover plate, and a buckle bolt which is buckled with the buckle seat is rotatably connected to the top of the clamping block through a rotating shaft.

[0017] The above technical solution is adopted to limit the position of the card block.

[0018] The utility model is further configured as follows: a bearing grid used in conjunction with the moisture absorbing masterbatch is installed inside the cavity.

[0019] The above technical solution is adopted to carry the hygroscopic masterbatch.

[0020] In summary, the utility model has the following beneficial effects:

[0021] 1. The utility model installs a cavity at the bottom of the support shell, and hygroscopic masterbatch is installed inside the cavity. When the negative pressure fan inside the exhaust seat on the top of the cover plate is started, the external airflow enters the support shell through the air inlet groove, and the hygroscopic masterbatch absorbs moisture and filters dust during the process, thereby ensuring the dryness and cleanliness of the air, ensuring the dustproof and waterproof effect, and improving the ventilation and heat dissipation effect inside the support shell;

[0022] 2. The utility model has a slot body on the cover plate, and a card block is installed inside the slot body. When the cover plate and the support shell need to be installed together, it is only necessary to insert the protrusion of the cover plate into the inside of the support shell and insert the card block into the card slot of the support shell. No bolts are needed, which improves the speed and efficiency of installation. BRIEF DESCRIPTION OF THE DRAWINGS
