Description

Technical Field

[0001] The invention belongs to the technical field of doors and windows, and in particular relates to a method for using a combined rat-proof door for an equipment room. Background Art

[0002] There are a large number of cables, transformers, switch cabinets and other important equipment in equipment rooms such as subway station substations and communication rooms. If small animals such as rats enter, it will pose a huge safety hazard to the operation of the subway. Therefore, it is necessary to set up rat-proofing measures at the doors of relevant rooms.

[0003] At present, the rat-proofing measures in subway stations are generally to install a rat-proof board on the inside of the equipment room door. This method has the following shortcomings: 1. An additional slot with the same width as the door must be set on the inside of the door, which is inconvenient to install and there is a waste of installing extra rat-proof boards; 2. When installation and maintenance operations are carried out indoors, the rat-proof board must be removed and stored, and then installed after the operation is completed. The operation process is relatively complicated, causing inconvenience in use and requiring storage space; 3. In an emergency, the setting of the rat-proof board is not conducive to the rapid evacuation of personnel. Summary of the invention

[0004] The problem to be solved by the present invention is to provide a method for using a combined rat-proof door for an equipment room, which is particularly suitable for users to solve many problems existing in traditional rat guards, such as inconvenient installation, inconvenient use, inconvenient management and storage, and inconvenient evacuation.

[0005] In order to solve the above technical problems, the technical solution adopted by the present invention is: to provide a method for using a combined rat-proof door for an equipment room, comprising a door leaf and a door frame, the door leaf being rotatably installed in the door frame, the door leaf comprising an upper door leaf and a lower door leaf, a transmission rod being vertically slidably arranged in the upper door leaf, teeth being symmetrically arranged on both side walls of the transmission rod, a door handle being rotatably arranged on the upper door leaf, a first transmission gear being arranged in the upper door leaf, the first transmission gear being coaxially connected to the door handle, and the first transmission gear being meshed with teeth on one side of the transmission rod, a third transmission gear being rotatably arranged on the inner side of the upper door leaf, one side of the third transmission gear passing through the inner side wall of the upper door leaf, and the third transmission gear being meshed with teeth on one side of the transmission rod, The third transmission gear is meshed with the teeth on the other side of the transmission rod, a plug rod is vertically slidingly provided in the lower door leaf, and teeth are provided on one side wall of the plug rod, a second transmission gear is vertically rotated in the lower door leaf, the second transmission gear is meshed with the teeth on the side wall of the plug rod, a through hole is provided at the top of the lower door leaf, the top free end of the plug rod passes through the through hole, a blind hole is vertically provided at the bottom of the upper door leaf, the top free end of the plug rod is inserted into the blind hole, a slot one is provided at the top of the lower door leaf, the bottom free end of the transmission rod is inserted into the slot one, and the teeth on one side of the transmission rod are meshed with the second transmission gear, a ground slot is vertically provided at the bottom of the door frame, and the bottom free end of the plug rod is inserted into the ground slot.

[0006] Furthermore, a push rod lock is inserted into the inner wall of the upper door leaf, a pressure block is horizontally arranged on the push rod lock, a slot two is arranged on the inner wall of the upper door leaf, the pressure block is inserted into the slot two, and a return spring is arranged between the bottom of the pressure block and the bottom of the inner side of the slot two, a beveled tooth block is arranged on one end of the push rod lock, and beveled teeth are arranged on the third transmission gear, and the beveled tooth block matches the bevel teeth of the third transmission gear.

[0007] A method for using a combined rat-proof door for an equipment room comprises the following steps:

[0008] The door handle is turned downward at a small angle, at which time the transmission rod is not inserted into the slot 1, and the lower door leaf is still fixed by the slot connected by the insertion rod, and is used as a rat-proof door;

[0009] Close the upper door leaf, then turn the door handle downward at a large angle, control the transmission rod downward into slot 1 of the lower door leaf through the first transmission gear, and drive the second transmission gear to rotate through the transmission rod, and the second transmission gear drives the top of the insertion rod upward into the upper door leaf, and at the same time, the bottom of the insertion rod is pulled out of the ground slot, and the above operations realize the combination and opening of the upper and lower door leaves.

[0010] In an emergency (such as fire), push the push rod lock from indoors, the helical tooth block of the push rod lock and the third transmission gear rotate, thereby driving the transmission rod, the second transmission gear and the insertion rod to move together, so that the transmission rod moves down to slot one and the insertion rod moves up from the ground slot, opening the upper door leaf and the lower door leaf together.

[0011] When the door needs to be restored to the separated state, the door leaf is closed into the door frame, the door handle is turned upward, and the transmission rod is controlled by the first transmission gear to be retracted upward into the upper door leaf. At the same time, the transmission rod drives the second transmission gear, and the second transmission gear drives the insertion rod to be inserted into the ground slot to realize the separation of the upper and lower door leaves.

[0012] The advantages and positive effects of the present invention are: due to the adoption of the above technical solution, the rat guard is combined with the traditional equipment room door, that is, there is no need to set up a rat guard separately, so that the degree of component integration is high, and the installation and removal speed of the rat guard at the entrance and exit of the subway equipment room is slow and difficult to operate. The installation and use costs are saved, the efficiency of equipment handling is improved, and the local space layout is optimized. At the same time, it can prevent people from being tripped and improve the safety of personnel evacuation in emergency situations. The rat-proof door can be used in underground spaces such as subway stations or equipment room doors with relevant needs to block small animals; and the present invention has the advantages of convenient use, strong reliability, and cost saving.
