Problems solved by technology

However, due to the limitation of the inclination angle of the locking slider, it is still necessary to manually open the door body (open to the state where people can freely enter and exit), close (close to the lock pin on the door body and the lock block on the door frame) corresponding position)
Because the door body is heavy, it is laborious, and it also affects the speed of opening the door, which is laborious and time-consuming, causing inconvenience to the work

Embodiment 1

[0019] Embodiment one: see Figure 1-3 , a fully automatic electromagnetic shielded door with an emergency opening device, comprising a door frame 1 and a door body 2, the door body 2 is hingedly installed in the door frame 1 through two hinges 3 arranged up and down on the first side. Two lock pins 4 are arranged up and down on the side B corresponding to the side A of the door body 2, and the two lock pins 4 are arranged laterally along the surface of the door body 2, and a connecting rod 6 is fixedly connected to the two lock pins 4, and the two lock pins 4 are connected to each other. The rods 6 are arranged concentrically and are respectively guided and slidably assembled through the corresponding fixed guide rails on the door body 2. Coaxial handwheels 7 are respectively rotated and installed in the middle of the inner and outer sides of the door body 2. The handwheel 7 is driven and connected with a gear rack Transmission mechanism, wherein, the hand wheel 7 is meshed w...

Embodiment 2

[0024] Embodiment two: see Figure 4-5 , Embodiment 2 is basically the same as Embodiment 1, and the similarities will not be repeated. The difference is that it also includes an emergency opening mechanism. The emergency opening mechanism includes a motor drive mechanism 10, a passive bevel gear 23, and a positioning ring groove 24. , positioning steel ball 25, rotating shaft 26, driving bevel gear 27, mounting frame 28, top cover 29 and spring 30.

[0025]The motor drive mechanism 10 is a two-axis motor, and the output shaft at one end of the two-axis motor is connected to the upper locking slider 5 through the rack and pinion transmission mechanism 9, so that the two locking sliders 5 can be driven to synchronize along the corresponding slide rail 8 Swipe up and down. A passive bevel gear 23 is fixedly installed on the output shaft of the other end of the double-axis motor, and a mounting frame 28 is fixed near the double-axis motor on the door frame 1, and a rotating shaf...

Abstract

A full-automatic electromagnetic screen door with an emergency opener comprises a door frame, a door body and a locking mechanism mounted between the door body and the door frame, the door body is hinged within the door frame through two hinges disposed on upper and lower portions of a side one, respectively, the side of the door body where the locking mechanism is located is fixedly provided with fastening heads, the door frame is fixedly provided with a fixing device close to the side one of the door body, the fixing device is connected with a door pivot-opening unit horizontally rotating along the fixing device, the door pivot-opening unit is provided with locking grooves in a generatrix direction, and the fastening heads are fastened in the fastening grooves; an engaging-disengaging device is disposed inside the door pivot-opening unit, an engaging-disengaging switch connected with the engaging-disengaging device is arranged above the door pivot-opening unit and is connected with a pull spring and a pull cord that apply opposite acting forces, the other end of the pull spring is fixed to the door pivot-opening unit, and the other end of the pull cord is wound to a hand wheel. By rotating the hand wheel on the inner side of the door body, the rotation of the hand wheel drives the pull cord, the pull cord pulls the engaging-disengaging switch so that the engaging-disengaging device disengages; when the hand wheel rotates, the hand wheel drives two lock pins to move up and down so that the door body is opened or locked.

Description

technical field [0001] The invention belongs to the technical field of electromagnetic shielding doors, and mainly relates to a fully automatic electromagnetic shielding door with an emergency opening device. Background technique [0002] At present, the screen door installed in the electromagnetic shielding room mainly adopts the swing door connected by hinges, and the opening and closing of the screen door has two kinds of locking mechanisms: electric control lock and manual lock. The electromagnetic shielded door that adopts electronic control to open and close only uses the biaxial motor installed above the door body to drive the locking slider installed on the door frame through the rack transmission mechanism, and utilizes the tilt angle on the locking slider to , so that when the lock pin installed on the door body is separated from the locking slider, the door body is separated from the door frame. However, due to the limitation of the inclination angle of the locki...
