Description

Security door

Technical Field

The utility model relates to a security installations field indicates a security inspection door very much.

Background

The security door is mainly used for detecting metal objects and used in places with dense pedestrian streams, and when pedestrians and luggage pass through the security door, whether the large metal objects are carried or not can be automatically detected. Conventional security doors are generally designed to be fixed, and the door frame is generally placed directly on the ground, and no movable device is provided for the door frame, and the security door is generally not required to be moved. However, if the security doors are arranged at a dense pedestrian flow and the positions of the security doors need to be adjusted, such as in a subway station, the people flow can be guided and distributed more conveniently if the positions of the security doors can be adjusted according to the number of the pedestrian flow.

Based on this, the chinese utility model patent publication No. CN207650412U proposes a movable security inspection door, which includes a door frame and a roller connected to the bottom of the door frame through a screw, wherein the door frame includes a left door plate, a right door plate and a control box connected to the two door plates, the control box is connected to the tops of the two door plates, the roller is a universal wheel, and a brake pedal is arranged on the universal wheel, and the brake pedal is hinged to the universal wheel; the bottom of the door frame is connected with at least four rollers, and each roller is provided with a brake pedal; the control box includes integrated circuit board, alarm, controller, power and a plurality of joint, all is provided with a plurality of magnetic induction coils in left door plant and right door plant, and alarm and controller electricity are connected and are set up on integrated circuit board, and integrated circuit board is connected to the equal electricity of controller, power, a plurality of joint and magnetic induction coil. The utility model discloses can conveniently remove the security check door, can fix the security check door again and place subaerial.

The above scheme can solve the fixing problem of the security inspection door to a certain extent, but still has the following problems: most of the existing rollers comprise metal parts, and when the movable security inspection door is high in sensitivity, false alarm is possibly caused by the metal parts of the rollers, so that normal use of the security inspection door is influenced; moreover, when the security door is fixed for use, the surface of the universal wheel may be worn due to friction, and the roller may not be used for a long time.

Therefore, how to provide a movable security inspection door which can avoid false alarm and reduce roller loss becomes a technical problem which needs to be solved urgently in the industry.

Disclosure of Invention

The purpose of the invention is as follows: in order to overcome the defects in the prior art, the invention provides a security inspection door, and aims to provide a scheme for solving the problems of misinformation and large roller loss in the existing scheme.

The technical scheme is as follows: a security door, comprising:

the magnetic induction door comprises two door plates which are oppositely arranged, wherein a plurality of magnetic induction coils are arranged in the door plates, a cavity is arranged at the lower end of each door plate, at least two idler wheels are arranged in the cavity, and the idler wheels are connected with the cavity through an ejection assembly for driving the door plates to move along the vertical direction;

and the control box is connected with the top ends of the two door panels.

Further, the ejection assembly includes:

a support rod for connecting the roller;

and one end of the lever is hinged to the inner wall of the cavity, one end of the lever extends out of the outer side of the door plate, and the middle part of the lever is hinged to the supporting rod.

Furthermore, the idler wheel is a universal wheel, and a brake pedal is arranged on the universal wheel.

Furthermore, a shielding layer for preventing electromagnetic radiation from passing through is arranged on the inner wall of the cavity.

Further, the shielding layer is a lead coating.

Furthermore, at least two rollers are arranged in each door panel.

Has the advantages that: according to the security inspection door, the cavity is formed in the bottom end of the door plate, the roller is arranged in the cavity, and therefore the metal part of the roller is prevented from interfering the magnetic induction coil in the door plate, the occurrence of false alarm events is avoided, and the detection efficiency is improved.

Detailed Description

In order to make the objects, technical solutions and advantages of the present invention more apparent, the present invention is described in further detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the invention and are not intended to limit the invention. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.

It should be noted that the description relating to "first", "second", etc. in the present invention is for descriptive purposes only and is not to be construed as indicating or implying relative importance or implicitly indicating the number of technical features indicated. Thus, a feature defined as "first" or "second" may explicitly or implicitly include at least one such feature. In addition, technical solutions between various embodiments may be combined with each other, but must be realized by a person skilled in the art, and when the technical solutions are contradictory or cannot be realized, such a combination should not be considered to exist, and is not within the protection scope of the present invention.

Referring to fig. 1 to 3, an embodiment 1 of the security door of the present invention includes a door panel 1 and a control box 2. The door plate comprises two door plates 1 which are arranged vertically and oppositely, a plurality of magnetic induction coils are arranged in each door plate 1, a cavity 4 is arranged at the lower end of each door plate 1, at least two idler wheels 3 are arranged in each cavity 4, and the idler wheels 3 are connected with the cavities 4 through ejection assemblies used for driving the door plates to move along the vertical direction.

The control box 2 comprises a controller, an alarm, a driving circuit and a liquid crystal display screen, and is arranged at the top end of the door panel 1 and connected with the two door panels 1. According to the security inspection door, the cavity is formed in the bottom end of the door panel 1, the roller is arranged in the cavity 4, and the metal part of the roller 3 is prevented from interfering the magnetic induction coil in the door panel 1, so that the occurrence of false alarm events is avoided, and the detection efficiency is improved.

As a further optimization of this embodiment, the ejection assembly comprises: a support bar 31 and a lever 32. The support rod 31 is vertically arranged and is used for connecting the roller 3; one end of the lever 32 is hinged to the inner wall of the cavity 4, the other end of the lever extends out of the outer side of the door panel 1, and the middle part of the lever 32 is hinged to the supporting rod 31. Preferably, two levers 32 in the same door panel 1 are integrally connected after extending out of the door panel 1, so as to form a handle 33 convenient for manual operation. When the door is used, one end of the lever 32 extending out of the door panel 1 is pressed, the support rod 31 serves as a middle pressure bearing part, one end of the lever 32 located in the cavity 4 drives the door panel 1 to move upwards, so that the door panel 1 leaves the ground, and the roller 3 is exposed to form a movable state; when the door does not need to be moved, the end of the lever 32 extending out of the door panel 1 is lifted up, the lever 32 drives the door panel 1 to move down, and the roller 3 retracts into the cavity 4 and cannot move.
