Description

Anti-dismantling structure suitable for casing type installation

Technical Field

The utility model relates to a prevent tearing open the equipment field, concretely relates to prevent tearing open structure suitable for casing type installation.

Background

For the electronic device installed in the metal pipeline and the metal box body, a general anti-dismantling mode is to paste a fragile paste at a key position and use the fragile paste as a proof of whether the electronic device is privately dismantled by a user according to whether the electronic device is broken or not. However, the method can only be used as a mark for proving whether the user privately carries out disassembly and assembly, and after the user privately carries out disassembly and assembly, the user can only know whether the user privately carries out disassembly and assembly through the examination of annual inspection personnel in the annual inspection period, and the real-time monitoring cannot be carried out. And the fragile sticker is easy to purchase, and the identification accuracy is not high.

SUMMERY OF THE UTILITY MODEL

The not high technical problem of the degree of accuracy of real-time supervision, discernment can not be realized to the mode of preventing tearing open for solving prior art, the utility model provides a solve the structure of preventing tearing open that is applicable to the installation of sleeve type of above-mentioned problem.

An anti-disassembly structure suitable for sleeve type installation comprises an outer sleeve ring, an inner sleeve ring, a magnet, a reed pipe and a monitoring circuit; the inner sleeve ring and the outer sleeve ring are of cylindrical structures, the inner sleeve ring is sleeved outside the pipeline, the outer sleeve ring is sleeved outside the inner sleeve ring, the inner wall of the outer sleeve ring is provided with a magnet, a reed pipe is arranged at the position, close to the magnet, of the outer wall of the inner sleeve ring, and the inner sleeve ring is further provided with the monitoring circuit connected with the reed pipe.

The utility model provides a be applicable to the sleeve type installation prevent tearing open a preferred embodiment of structure, the interior lantern ring includes first half, second half, in the pipeline outer wall amalgamation.

In a preferred embodiment of the anti-tamper structure adapted for sleeve-type installation, the inner sleeve ring and the outer sleeve ring are connected by screw threads, and when screwing is ensured by structural design, the magnet is located at the position closest to the reed pipe.

The utility model provides a be applicable to the sleeve type installation prevent tearing open a preferred embodiment of structure, monitoring circuit includes with circuit connection's detecting element, processing unit, communication unit to and the battery for each unit power supply.

Compared with the prior art, the utility model provides a be applicable to the break-make that the distance change that prevents tearing open structure between magnet and the tongue tube realized the circuit of casing type installation, as the judgement foundation whether the judgement equipment is unpacked apart. On one hand, the recognition accuracy is higher than that of the traditional fragile sticker, and on the other hand, remote real-time monitoring can be conveniently realized on the basis of the detection mode.

Drawings

Fig. 1 is a schematic structural diagram of an anti-dismantling structure suitable for casing type installation.

Detailed Description

The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments.

Please refer to fig. 1, which is a schematic structural diagram of an anti-detaching structure 1 suitable for casing installation according to the present invention.

The anti-dismantling structure 1 suitable for sleeve type installation comprises an inner sleeve ring 2 and an outer sleeve ring 3. Wherein the inner collar 2 comprises an upper half 21, a lower half 22, a reed switch 23, a battery 24 and a PCB 25; the outer collar 3 comprises a magnet 31.

The reed pipe 23 is arranged in the upper half part 21 and close to the outer wall, and the PCB 25 is arranged beside the reed pipe and is connected with the reed pipe through a circuit. The lower half part 22 is provided with a No. 5 battery for supplying power to the PCB 25 and the reed switch 23. The upper half part 21 and the lower half part 22 are mutually spliced to form the cylindrical inner lantern ring 2, the cylindrical inner lantern ring is sleeved on the outer wall of the gas pipeline 4, and contacts are arranged on the contact surfaces of the upper half part and the lower half part to realize electric conduction.

Further, the inner collar 2 should be sleeved on a key position of the gas pipeline 4, that is, the inner collar 2 and the outer collar 3 must be disassembled first when the pipeline is disassembled.

The PCB is integrated with a detection circuit for detecting the on-off of the reed switch 23, and an MCU and a Bluetooth for processing detection signals and transmitting the detection signals to the gas meter in a wireless mode. This part of the structure is a common technique in the art and will not be described herein.

The magnet 31 is arranged in the outer collar 3. The outer wall of the inner lantern ring 2 and the inner wall of the outer lantern ring 3 are provided with matched threads. And when the outer collar 3 is tightened, the magnet 31 is located at the position closest to the reed pipe 23.

The basic principle is as follows: normally, the magnet 31 magnetizes the contact of the reed switch 23 to keep the contact, and the circuit is kept open. When the outer collar 3 is disassembled, the magnet 31 is far away from the reed pipe 3, and the contact is disconnected, so that an open circuit is formed.

The detection circuit and the MCU transmit the characteristic signal to the gas meter. At present, most of the intelligent meters are networked, and signals can be directly merged into a server of a gas company to realize real-time monitoring.

The above only is the embodiment of the present invention, not limiting the scope of the present invention, all the equivalent structures or equivalent processes made by the present specification can be changed, or directly or indirectly applied to other related technical fields, and all the same principles are included in the protection scope of the present invention.
