Description

Technical Field

[0001] The utility model relates to the technical field of security, in particular to a security door with blocking. Background Art

[0002] Security gates are mainly used to detect whether people coming in and out are carrying prohibited items containing metal materials, such as guns, controlled knives and other dangerous metal materials. They are widely used in large public activity places such as civil aviation, stations, docks, museums, stadiums, and production and processing enterprises.

[0003] At present, most security gates sound an alarm when an abnormality is detected, which prompts security personnel to intercept the inspected person. This interception work is mostly completed by the staff, which requires security personnel to pay attention to which inspected person the alarm is issued by the security gate in real time, and also requires security personnel to quickly move in front of the person, stop him, and conduct further verification and inspection. When the crowd is large and crowded, how to accurately find and intercept the person also increases the difficulty and intensity of the work of security personnel; and increasing the difficulty and intensity of work will also make people easily tired during long-term work and increase the possibility of negligence.

[0004] In addition, some existing niche products may have interception devices installed on the security gates, but generally such interception devices are complex in design and may occupy the area through which the security gates pass, affecting normal passage, and requiring substantial modifications to the security gates.

[0005] Based on this, it is necessary to develop a security door that can automatically intercept and has a simple structure and can be easily produced and modified based on the existing security door. Utility Model Content

[0024] The principles and features of the present invention are described below in conjunction with the accompanying drawings. The examples given are only used to explain the present invention and are not used to limit the scope of the present invention.

[0025] Example 1

[0026] like Figure 1 As shown, the security door with blocking function in this embodiment includes a security door body 1 and an automatic blocking structure 2. The automatic blocking structure 2 is installed on one side of the security door body 1 to intercept or avoid people or objects passing through;

[0027] Among them, the automatic blocking structure 2 includes two groups of rotating mechanisms 21, rotating arms 22 and flexible blocking structures 23. The two groups of the above-mentioned rotating mechanisms 21 are respectively installed on one side of the vertical beams at both ends of the above-mentioned security door body 1, and one end of the two above-mentioned rotating arms 22 is respectively connected to the two groups of the above-mentioned rotating mechanisms 21 for transmission. The above-mentioned flexible blocking structure 23 is installed between the other ends of the two above-mentioned rotating arms 22. The two groups of the above-mentioned rotating mechanisms 21 are used to synchronously drive the two above-mentioned rotating arms 22 to rotate upward to vertical, and move the above-mentioned flexible blocking structure 23 to one side of the upper end cross beam of the above-mentioned security door body 1, or synchronously drive the two above-mentioned rotating arms 22 to rotate downward to vertical or inclined, and move the above-mentioned flexible blocking structure 23 to the lower part of one side of the above-mentioned security door body 1.

[0028] During use, the two sets of rotating mechanisms 21 operate synchronously, driving the two rotating arms 22 to flip downward to a vertical position and abut against one side of the two end vertical beams of the security door body 1, and the flexible blocking structure 23 will be intercepted at the middle and lower part of one side of the security door body 1, and it is a flexible structure itself, so it will not cause harm to personnel during interception. When interception is not needed, the rotating mechanism 21 drives the two rotating arms 22 to flip upward to a vertical position against the upper part of one side of the security door body 1, and the flexible blocking structure 23 will fall on one side of the upper end cross beam of the security door body 1, and will not stay in the area where the security door body 1 passes, and will not affect normal passage.

[0029] As a preferred embodiment, the rotating mechanism 21 includes a mounting plate 211 and a first motor 212. The mounting plate 211 is vertically mounted on one side of the vertical beam of the security door body 1. The first motor 212 is mounted on one end of the mounting plate 211. The main shaft of the first motor 212 passes horizontally through the mounting plate 211 and is connected and fixed to one end of the rotating arm 22.

[0030] In the above embodiment, the two first motors 212 rotate synchronously at the same angle, which can drive the two rotating arms 22 to flip up and down to achieve the interception or non-interception state. The first motor 212 can be installed on one side of the security door body 1 through the mounting plate 211, and can be installed on the basis of the existing security door body 1. It has good versatility and can be applied to the modification of different types of security doors.

[0031] In this embodiment, the flexible blocking structure 23 includes two bar-shaped connecting blocks 231 and a plurality of flexible blocking cables 232. The two connecting blocks 231 are respectively installed at the other ends of the two rotating arms 22 and are parallel to the rotating arms 22. The plurality of blocking cables 232 are vertically connected between the two connecting blocks 231 and are spaced apart along the length direction of the connecting blocks 231. The flexible blocking structure 23 has a simple structural design and can achieve interception through a plurality of blocking cables 232.

[0032] In this embodiment, the barrier rope 232 is a conventional elastic rope.

[0033] In this embodiment, the ends of the two connecting blocks 231 close to each other are provided with hanging rings at intervals along the length direction thereof, and hooks connected to the hanging rings are provided at both ends of the blocking rope 232. Both ends of the blocking rope 232 are assembled with hooks and hanging rings, which are easy to disassemble and assemble.

[0034] Example 2

[0035] like Figure 2As shown, the security door with blocking function in this embodiment includes a security door body 1 and an automatic blocking structure 2. The automatic blocking structure 2 is installed on one side of the security door body 1 to intercept or avoid people or objects passing through;

[0036] Among them, the above-mentioned automatic blocking structure 2 includes two sliders 24 and a pulling mechanism 25. The two sliders 24 are respectively slidably mounted on one side of the vertical beams at both ends of the above-mentioned security door body 1. The above-mentioned pulling mechanism 25 is mounted on the upper end of the above-mentioned security door body 1 and connected to the upper ends of the two sliders 24. A flexible blocking net 26 is provided between the two sliders 24. The above-mentioned pulling mechanism 25 is used to drive the two sliders 24 to move upward to the upper part of one side of the above-mentioned security door body 1, or drive the two sliders 24 to move downward to the middle or lower part of one side of the above-mentioned security door body 1.

[0037] During use, the pulling mechanism 25 drives the two sliders 24 to move up and down synchronously, so that the two sliders 24 and the blocking net 26 can move upward to one side of the upper crossbeam of the security door body 1 or the middle and lower part of the security door body 1, which plays a good interception role, and the non-interception state will not affect the passage. The overall design can use a conventional security door, and it can be used with only a slight modification, and it has good versatility.

[0038] As a preferred embodiment, the pulling mechanism 25 includes a rotating shaft 251, a second motor 252 and two take-up wheels 253. The rotating shaft 251 is horizontally arranged, and its two ends are respectively mounted on the upper end of the security door body 1 through side plates rotatably connected thereto. The second motor 252 is transmission-connected to one end of the rotating shaft 251, and the two take-up wheels 253 are respectively coaxially mounted on the two ends of the rotating shaft 251. Pulling ropes 254 are respectively wound on the take-up wheels 253, and the pulling ropes 254 are respectively connected to the upper ends of the two sliders 24 one by one.

[0039] In the above implementation scheme, the second motor 252 drives the rotating shaft 251 to rotate, which can drive the two take-up wheels 253 to rotate synchronously, thereby realizing the winding and unwinding operations of the two pulling ropes 254. During the winding or unwinding process, the two sliders 24 can be pulled upward to one side of the crossbeam of the security door body 1, or slide downward to the middle and lower part of the security door body 1 under the action of gravity. The operation is very simple.
