Description

Technical Field

[0001] The utility model is applicable to the technical field of communication cabinets, and particularly relates to a communication cabinet which is convenient for internal maintenance. Background Art

[0002] At present, communication cabinets are a common type of communication equipment. With the continuous development of communication technology, people have higher and higher requirements for the use of communication cabinets. As the service life of communication cabinets continues to increase, maintenance personnel are often required to inspect and repair the communication equipment inside the communication cabinets.

[0003] However, when maintenance personnel are inspecting the interior of the communication cabinet, although there is a rain shield frame on the top of the communication cabinet, such a rain shield only protects the communication cabinet from rain, but there is no corresponding rain shield mechanism at the front of the communication cabinet door. As a result, when maintenance personnel stand in front of the communication cabinet to inspect the interior, rainwater dripping from above is very likely to drip into the maintenance cabinet, which will affect the maintenance work and delay the maintenance efficiency. Therefore, we propose a communication cabinet that is easy to inspect internally. Utility Model Content

[0004] The main purpose of the utility model is to provide a communication cabinet which is convenient for internal maintenance and can effectively solve the problems in the background technology.

[0005] In order to achieve the above purpose, the technical solution adopted by the utility model is:

[0006] A communication cabinet convenient for internal maintenance comprises a cabinet body, a cabinet door is hingedly connected to the side of the cabinet body through a rotating shaft, heat dissipation grooves are provided inside both ends of the cabinet body side, a hollow frame is fixedly installed on the top surface of the cabinet body, and a movable frame is movably installed inside the hollow frame;

[0007] Fixed rods are fixedly installed on both sides of the movable frame, and a rain shield is rotatably sleeved on the outer surface of each fixed rod, and the rain shield is movably installed inside the movable frame, and a return torsion spring is movably sleeved on the middle end surface of each fixed rod;

[0008] A transmission frame is fixedly installed on the middle end surface of the top of the hollow frame, a rotating screw is rotatably installed inside the transmission frame through a bearing, a transmission sleeve is movably sleeved on the outer surface of the rotating screw, a transmission rod is fixedly installed on the bottom surface of each transmission sleeve, and the transmission rod is slidably installed in the transmission frame and the hollow frame, and the bottom of the transmission rod is fixedly connected to the top of the movable frame.

[0009] By adopting the above technical solution, through the rotation transmission action of the screw rod on the transmission sleeve, and the reset pushing action of the reset torsion spring, the hollow frame and the rain shield can be used to shield the top of the front end of the cabinet to prevent rainwater from dripping from the front end of the cabinet into the interior and affecting the maintenance efficiency of the maintenance personnel inside the cabinet, and simultaneously prevent rainwater from corroding the communication parts inside the cabinet and affecting normal use.

[0010] As an optional solution of the technical solution of the present application, a servo motor is fixedly installed on the inner side of the transmission frame, and the side of the servo motor transmission shaft is fixedly connected to the top surface of the side of the rotating screw through a coupling.

[0011] By adopting the above technical solution, the corresponding driving force is provided to the rotating screw drive through the structural action of the servo motor.

[0012] As an optional solution of the technical solution of the present application, the bottom of the transmission frame and the middle end of the top of the hollow frame are both provided with limit grooves, and the transmission rod passes through and is slidably inserted into the limit grooves.

[0013] By adopting the above technical solution, the transmission adjustment rationality of the entire device is ensured by the guiding and limiting effect of the limiting groove on the transmission rod.

[0014] As an optional solution of the technical solution of the present application, abutment blocks are fixedly installed on the inner surface of both ends of the hollow frame, and the side edges of the abutment blocks are movably fitted to the outer surface of the rain shield.

[0015] By adopting the above technical solution, the rain shield can be pushed and restored to its position when it moves and restores due to the structural action of the abutment block.

[0016] Compared with the prior art, the utility model has the following beneficial effects:

[0017] The technical solution of the present application is a communication cabinet that is convenient for internal maintenance. By sleeve-connecting a transmission sleeve to the surface of a rotating screw rod, the transmission sleeve can be horizontally moved inside a transmission frame under the rotational transmission action of the rotating screw rod, and then the movable frame can be synchronously moved forward inside a hollow frame and moved out, so that the hollow frame can be shielded from rain on the top of the front end of the cabinet, thereby preventing rain from arbitrarily dripping from the front end of the cabinet into the interior thereof and affecting the maintenance efficiency of the maintenance personnel inside the cabinet, and simultaneously preventing rain from corroding the communication parts inside the cabinet and affecting normal use;

[0018] Through the structural action of the fixing rod and the reset torsion spring, the fan-shaped rain shield can be moved out of the hollow frame. After the side of the actuating block is separated from the outer side of the rain shield and the rain shield loses its actuating and limiting force, the rain shield can be rotated and spread open from both sides of the hollow frame under the restoring push of the reset torsion spring, thereby increasing the rain protection area of ​​the hollow frame and the top of the cabinet, further improving the maintenance efficiency of the maintenance personnel.
