Description

Technical Field

[0001] The utility model relates to the field of passage doors, and particularly relates to an anti-theft safety passage door. Background Art

[0002] As an important safety protection device, the anti-theft safety passage door is widely used in multiple fields, including but not limited to: places that require high protection of property safety, such as libraries, museums, archives, shopping malls and supermarkets. These places usually store a large number of books, cultural relics, archives or commodities. Therefore, the anti-theft safety passage door plays a crucial role in these places. Through its unique anti-theft technology and structural design, it effectively prevents unauthorized goods from entering and leaving and theft behavior.

[0003] The existing anti-theft detection passage door mainly consists of the following parts: an anti-theft detection transmitter and a receiver, which are respectively located on both sides of the passage door and are used for transmitting and receiving specific signals (such as electromagnetic waves, radio waves or acousto-magnetic signals). The outer shell is usually made of acrylic or metal materials, which is used to protect the internal components and provide an aesthetic appearance. It also includes a speaker and an alarm light, which are used to emit sound and light signals when an unauthorized item passes through, reminding the loss prevention staff or security personnel, thus achieving the anti-theft effect.

[0004] However, although the existing anti-theft passage doors meet the safety protection requirements to a certain extent, there are still defects. The installation structure of the detection end of the existing passage doors is relatively simple, and it is easily damaged or detached due to external collisions, thus affecting the stability and reliability of the installation. In addition, a detection controller is usually arranged inside the base of the existing passage door, and the existing heat dissipation for it only relies on its own structure or simple through-hole settings, resulting in being not conducive to long-term use, thus affecting the detection service life and reliability.

The installation end of the detection housing is connected to the base, and the detection end of the detection housing extends outward through the base. A magnetostrictive detection controller is connected inside the detection housing. An accommodation cavity for connecting the installation end is formed inside the base. A plurality of protruding positioning blocks are formed on the inner wall of the accommodation cavity, and a plurality of connection holes for connecting the installation end are provided in the accommodation cavity. A plurality of positioning slots are provided on the installation end. The installation end is paired and inserted with the positioning blocks through the positioning slots, and a plurality of installation holes coaxial with the connection holes are provided on the installation end. The installation holes are connected to the connection holes through connecting pieces.

[0008] Further, in the above description, the positioning blocks are formed inside the accommodation cavity, and the positioning blocks are distributed on both sides of the accommodation cavity. The positioning slots are distributed on both sides of the installation end and are paired with the positioning blocks.

[0009] Through the pairing of the positioning blocks and the positioning slots, the stability of the connection between the detection housing and the base is further improved, so that the detection housing can be limited, and the firmness and stability of use are improved.

[0010] Further, in the above description, a plurality of fixing holes for connecting with the outside are provided inside the base.

[0011] Through the provided fixing holes, in the specific implementation, expansion screws are used to fixedly connect with the external ground, improving the firmness and stability of the base, so that the connection between the detection housing and the base is more stable and reliable.

The positioning slots 9 are distributed on both sides of the installation end 3 and are paired with the positioning latches 7. Through the pairing of the positioning latches 7 and the positioning slots 9, the connection stability between the detection housing 2 and the base 1 is further improved, so that the detection housing 2 can be limited, and the firmness and stability of use are improved.

[0028] Fixing holes 13 for connecting to the outside are opened inside the base 1.

[0029] Through the provided fixing holes 13, in specific implementation, expansion screws are used to fixedly connect to the external ground, improving the firmness and stability of the base 1, so that the connection between the detection housing 2 and the base 1 is more stable and reliable.

[0030] A first fan 14 is connected to the inner wall of the accommodation cavity 6 near the air inlet hole 11, and a second fan 15 is connected to the inner wall of the accommodation cavity 6 near the air outlet hole 12. The input end of the first fan 14 extends towards the air inlet hole 11, and the output end of the first fan 14 extends towards the second fan 15. Through the first fan 14 and the second fan 15, the air inlet hole 11 and the air outlet hole 12 form a heat dissipation air duct. Specifically, by using the first fan 14 and the second fan 15, the air-cooled heat dissipation of the control components in the accommodation cavity 6 is accelerated, improving the stability and reliability of use.

[0031] A cover is snap-connected to the base 1. The cover is composed of a first cover plate 16 and a second cover plate 17. Both the first cover plate 16 and the second cover plate 17 are provided with clamping grooves 18 for clamping the detection housing 2 on the side surfaces close to the detection housing 2. A connection end 19 is formed on the first cover plate 16, and an installation groove 20 for clamping the connection end 19 is formed on the second cover plate 17.

[0034] For the specific installation and use in this embodiment, the fixing holes 13 of the base 1 are fixedly connected to the external ground through expansion bolts. Then, the assembled detection housing 2 is inserted into the accommodation cavity 6, and is inserted and paired with the protruding positioning block 7 through the positioning card slot 9, so as to quickly position the detection housing 2 and the base 1, simplify the assembly connection process between the detection housing 2 and the base 1, ensure the precise positioning between the detection housing 2 and the base 1, and effectively prevent problems such as shaking or misalignment caused by improper installation. At the same time, by combining the coaxial pairing of the mounting holes 10 and the connection holes 8 and tightening the connection with bolts, the stability and reliability of the connection structure are further enhanced. The air inlet holes 11 and the air outlet holes 12 provided on the base 1 form an effective heat dissipation channel. Driven by the first fan 14 and the second fan 15, an air convection is formed inside the accommodation cavity 6, so as to carry the heat generated by electronic components such as the acousto-magnetic detection controller 5 inside the base 1, form an air flow, and discharge it from the air outlet holes 12, effectively reducing the internal temperature of the accommodation cavity 6, ensuring the normal operation of the electronic components, and preventing performance degradation or damage caused by overheating.
