Description

TECHNICAL FIELD

[0001] The utility model relates to the technical field of access door, specifically, personnel access guide door. BACKGROUND

[0002] In the personnel centralized public place, safety has been the focus of government, society and operating unit, and its management content includes personal, property and public safety, etc., due to the diversification of the circulating personnel, the management of personnel is difficult.

[0003] In the safety management, the effective circulation of personnel is an important problem, and the smooth circulation of personnel in the place can improve the consumer experience and avoid the safety hidden danger caused by personnel congestion. At the same time, based on the fire prevention demand of the place, the fire door needs to be set in part to isolate, and the fire door is usually required to be closed to prevent emergency events.

[0004] Through market feedback, the closed fire door affects the personnel circulation efficiency on the one hand, and on the other hand, it is easy to cause personnel congestion. At present, the fire door configuration on the market is usually single side opening, and the single side opening in public places has the problem of unfairness of double side access conditions. Figure 1 The structure diagram of the general opening mode of the channel door in the prior art is shown: since the door leaf opening direction is B side, the A side traffic efficiency is higher than that of B side; the personnel traffic on A and B sides is easy to form personnel counterflow, and the traffic efficiency is reduced.

[0005] Therefore, a personnel access guide door is proposed. UTILITY MODEL CONTENT

[0024] The technical scheme of the utility model will be described clearly and completely in combination with embodiments. Obviously, the described embodiments are only part of the embodiments of the utility model, not all the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by the person skilled in the art without creative labor belong to the protection scope of the utility model.

[0025] Please refer to Figures 2-7 The utility model provides a technical scheme:

[0026] A personnel access guide door, comprising a door frame 101 installed in a personnel passageway; the door frame 101 is hinged with two door bodies 201, and any door body 201 is hinged with the door frame 101 through a spring hinge 901. When the two door bodies 201 are closed, the spring hinges 901 on the two door bodies 201 are respectively located at the two sides of the two door bodies 201. The installation mode of the spring hinges 901 makes the two door bodies 201 block the personnel passageway in a natural state, and the two door bodies 201 can rotate and open in opposite directions under the action of external force. Figure 4 From the perspective, the rotation range of the two door bodies 201 will be limited under the limitation of the spring hinges 901: the door body 201 located at the top can only rotate at the left side of the door frame 101, and cannot rotate to the right side of the door frame 101 after rotating into the door frame 101; the door body 201 located at the bottom can only rotate at the right side of the door frame 101, and cannot rotate to the left side of the door frame 101 after rotating into the door frame 101.

[0027] Any door body 201 is rotationally provided with a rotation shaft 301, any rotation shaft 301 is drivingly connected with a door locking mechanism, and the bottom cross beam of the door frame 101 is provided with two limit slots 401 corresponding to the two door locking mechanisms.

[0028] Referring to Figure 5 and Figure 6In the embodiment, in order to facilitate installation of the door locking mechanism, a sliding groove 501 is formed in the door body 201 and faces the corresponding limiting groove 401. Specifically, the door locking mechanism includes a crank 601 fixedly connected to the corresponding rotating shaft 301, a connecting rod 602 rotatably connected to one end of the crank 601 away from the rotating shaft 301, and a limiting strip 603 slidably connected to the sliding groove 501. The top end of the limiting strip 603 is rotatably connected to one end of the connecting rod 602 away from the crank 601, and the bottom end of the limiting strip 603 can extend into the corresponding limiting groove 401. When the two door bodies 201 are closed, the bottom ends of the two limiting strips 603 extend into the two limiting grooves 401 under the action of gravity, thereby locking the two door bodies 201 and preventing the two door bodies 201 from being pushed or pulled open.

[0029] Referring to Figure 7 When the bottom of the door body 201 moves to the bottom crossbeam of the door frame 101, in order to facilitate retraction of the bottom end of the limiting strip 603 into the sliding groove 501, the bottom end of the limiting strip 603 is designed as an arc surface structure. When the door body 201 is moved to the bottom crossbeam of the door frame 101 under the action of a pushing force or a pulling force, extrusion force exists between the arc surface structure and the bottom crossbeam of the door frame 101. One component of the extrusion force acts on the arc surface at the bottom of the limiting strip 603, and the force causes the limiting strip 603 to move upward and retract into the sliding groove 501. When the door body 201 is completely in the door frame 101, the limiting strip 603 falls into the limiting groove 401 under the action of gravity, thereby locking the door.

[0030] In the embodiment, in order to facilitate control of upward and downward movement of the limiting strip 603, both ends of the rotating shaft 301 extend out of the door body 201, and a handle 801 is mounted at each end of the rotating shaft 301. The handle 801 can be operated to control upward and downward movement of the limiting strip 603.

[0031] The above description is only preferred embodiments of the present application, and it should be understood that the present application is not limited to the forms disclosed herein, and should not be considered as excluding other embodiments, but can be used in various other combinations, modifications and environments, and can be modified within the scope of the concepts described herein by using the above teachings or related technologies or knowledge. Any modification and change made by those skilled in the art without departing from the spirit and scope of the present application should be within the scope of protection of the claims of the present application.
