Further, the hall switch is a unipolar hall switch, a bipolar hall switch or an all-pole hall switch.

Preferably, the hall switch is an all-pole hall switch.

Further, the magnet is fixed on the second shell in an adhering mode.

Further, be formed with the screw hole on the hall switch, the mounting panel corresponds hall switch is formed with the screw hole, hall switch passes through the screw fastening mode and installs on the mounting panel.

Further, the hall switch is fixed to the first housing in an adhering manner.

Further, the power source comprises a lithium battery or a button battery.

The utility model discloses a set up hall switch and come the response and dismantle the action on commodity to count through the counter, not only can discover that commodity is dismantled, also can take notes the number of times of being dismantled, have advantages such as effectual, low-power consumption, continuation of the journey length, can be used for the packing of commodity, the casing of commodity prevents tearing open, scenes such as after-sale appraisal.

Fig. 3 is a schematic view illustrating an installation of a hall switch according to another embodiment of the present invention.

Detailed Description

The present invention will be described in detail below with reference to the accompanying drawings and specific embodiments.

Referring to fig. 1 and 2, in this embodiment, the utility model provides a commodity anti-detaching device based on hall switch, including: first casing 1 and second casing 2, first casing 1 and second casing 2 are in the same place through the assembly structure assembly, first casing 1 orientation one side of second casing 2 is formed with mounting panel 11, be provided with hall switch 3 on mounting panel 11, this one end of hall switch 3's magnetic sensitivity is close to second casing 2, second casing 2 corresponds hall switch 3 is equipped with magnet 4, magnet 4 can be located through pasting the mode second casing 2 department, prevent that the dismouting is put still includes optoelectronic coupler 5, counter 6 and power 7, power 7 with hall switch 3 electric connection, optoelectronic coupler 5 with hall switch 3, counter 6 electric connection.

The utility model discloses the during operation, power 7 is used for giving hall switch 3 and optoelectronic coupler 5 provide operating voltage, hall switch 3 is used for the response magnet 4's state works as when first casing 1 and second casing 2 are dismantled the separation, magnet 4 is kept away from hall switch 3, hall switch 3 senses magnetic field variation, produces the high level, thereby makes optoelectronic coupler 5 works, and the produced signal of telecommunication sends for counter 6, the signal of telecommunication of counter 6 response and make the count number add 1. When first casing 1 and second casing 2 reconversion, magnet 4 gets back to the normal position again, hall switch 6 output low level, when being dismantled next time, can add 1 according to the last number of times of above-mentioned work flow work again. By adopting the scheme, whether the first shell 1 and the second shell 1 are disassembled or not can be known by checking the counting times of the counter 6, and the disassembling times are what.

It should be noted that, in this scheme, the distance between the magnet and the hall switch should meet the working requirement of the selected hall switch. The counter is connected with the Hall switch through the photoelectric coupler, so that the voltage can be isolated, and the condition of error counting caused by external magnetic field disturbance is prevented. The counter in the scheme belongs to a time sequence circuit for counting pulse times, the counter is widely applied in the prior art, the counter in the scheme can be completed by adopting the prior art, and the principle is not repeated. The anti-dismantling device of the scheme is not in conflict with other anti-dismantling means, so that the anti-dismantling device can be used together with the anti-dismantling means in the prior art to obtain a better using effect.

In some embodiments of the present disclosure, as shown in fig. 3, the hall switch 3A has a mounting screw hole 31A, the mounting plate 11A of the first housing 1A also has a screw hole, and the hall switch 3A is fixed on the mounting plate 11A by a screw fastening method. In some embodiments of the present disclosure, the hall switch may also be fixed on the mounting plate by means of adhesion.

In this scheme, hall switch can choose for use for unipolar hall switch, bipolar hall switch or full pole hall switch, preferably full pole hall switch, and above-mentioned embodiment is full pole hall switch promptly, and the model that common can choose for use is as: YS4913, YS1253 etc. do not appoint the magnetic pole when the all-pole Hall switch work, it is more convenient in the installation magnet process, need not have specific orientation, and the all-pole Hall switch work, magnet keep away from then can output high level. When the Hall switch is selected, the Hall switch preferably selects an element with low power consumption and high sensitivity, and the requirement on the response speed of the Hall switch is not high.

In the scheme, the power supply is used for working the Hall switch and the photoelectric coupler, the power supply can comprise a button cell or a lithium battery, and the power supply can also comprise a voltage stabilizing circuit. In specific application, in order to simplify the circuit, a hall switch capable of supporting a lower battery, such as an HAL248 series, can be selected, and the lower working voltage can be better adapted to the battery, so that the voltage stabilizing element and other materials are used less, the cost is reduced, the power is lower, and the cruising ability of the battery is improved.

To sum up, the utility model discloses a set up hall switch and come the response and dismantle the action on commodity to count through the counter, not only can discover that commodity is dismantled, also can take notes the number of times of being dismantled, have advantages such as effectual, low-power consumption, continuation of the journey length, can be used for the packing of commodity, the casing of commodity prevents tearing open, scenes such as after-sale appraisal.

The above description is only exemplary of the present invention and should not be construed as limiting the present invention, and any modifications, equivalents and improvements made within the spirit and principles of the present invention are intended to be included within the scope of the present invention.
