Description
Technical Field
The invention relates to a wire-breaking alarm device.
Background
With the rapid development of society and economy, markets and supermarkets are more and more, the scale is larger and larger, the theft prevention of commodities in the markets and supermarkets is an important part of the operation of the markets and supermarkets, the markets and supermarkets need to consider the reduction of labor cost and the improvement of customer experience, and meanwhile, the problem of commodity theft prevention is solved, which is a contradiction problem for the markets and supermarkets in practice. Particularly items of footwear that the consumer is required to try on. The existing anti-theft device for the shoes is fixed on the shoes through steel wires, and in practice, the condition that a malicious operator cuts the steel wires to take away the shoes often occurs.
Disclosure of Invention
Aiming at the problems in the prior art, the invention provides a wire breakage alarm device which can give an alarm in time when a malicious operator cuts a steel wire, and can improve the anti-theft performance of shoes.
In order to achieve the aim, the invention provides a wire breakage alarm device which comprises a cover body, a rotating shaft, a proximity switch and an L-shaped bracket, wherein the cover body is provided with a first opening and a second opening;
the rotating shaft is rotatably connected in the right end plate of the cover body, the part of the rotating shaft in the cover body is provided with an induction plate, the part of the rotating shaft outside the cover body is provided with a connecting plate corresponding to the induction plate, the induction plate is connected with the bottom of the cover body through a spring, and the end part of the connecting plate is provided with a connecting hole B;
the proximity switch is arranged in the cover body through the mounting seat, and the sensing surface of the proximity switch faces towards the right side and is matched with the sensing plate;
the vertical section of the L-shaped bracket is fixedly connected to the upper end of the cover body, the horizontal section of the L-shaped bracket extends towards the right side, and a connecting hole A is formed in the end part of the L-shaped bracket;
the connecting hole A and the connecting hole B are connected and tensioned through a steel wire rope, and the distance between the connecting hole A and the connecting hole B is the shortest in the tensioned state.
Preferably, the rotating shaft is connected with the right end plate of the cover body through a bearing.
And the proximity switch and the audible and visual alarm are connected with the controller.
In the invention, in a locking state, the steel wire rope pulls the connecting end of the connecting plate and the horizontal section of the L-shaped bracket to be in a nearest state, the induction plate is far away from the proximity switch at the moment, when the steel wire rope is cut off, the induction plate is pulled to the proximity switch under the action of the spring, the proximity switch induces the induction plate to send an induction signal to the processor, and the processor receives the induction signal and then controls the audible and visual alarm to give a local alarm to remind a salesperson to pay attention.
Drawings
Fig. 1 is a schematic structural view of the present invention.
In the figure: 1. the device comprises a cover body, 2, a rotating shaft, 3, an L-shaped support, 4, an induction plate, 5, a connecting plate, 6, connecting holes B and 7, a proximity switch, 8, connecting holes A and 9, a steel wire rope, 10 and a mounting seat.
Detailed Description
The present invention will be further explained below.
As shown in fig. 1, the disconnection warning device comprises a cover body 1, a rotating shaft 2, a proximity switch 7 and an L-shaped bracket 3;
the rotating shaft 2 is rotatably connected in a right end plate of the cover body 1, a sensing plate 4 is arranged on the part of the rotating shaft 2 in the cover body 1, a connecting plate 5 corresponding to the sensing plate 4 is arranged on the part of the rotating shaft 2 outside the cover body 1, the sensing plate 4 is connected with the bottom of the cover body 1 through a spring, and a connecting hole B6 is formed in the end part of the connecting plate 5;
the proximity switch 7 is installed in the cover body 1 through the installation seat 10, and the sensing surface of the proximity switch 7 faces towards the right side and is matched with the sensing plate 4;
the vertical section of the L-shaped bracket 3 is fixedly connected to the upper end of the cover body 1, the horizontal section of the L-shaped bracket extends towards the right side, and the end part of the L-shaped bracket is provided with a connecting hole A8;
the connecting hole A8 and the connecting hole B6 are connected and tensioned through the steel wire rope 9, and the distance between the connecting hole A8 and the connecting hole B6 is the shortest in the tensioned state.
The rotating shaft 2 is connected with the right end plate of the cover body 1 through a bearing.
The device further comprises a processor and an audible and visual alarm, wherein the proximity switch 7 and the audible and visual alarm are both connected with the controller.
When locking state, wire rope draws nearest state with the link of connecting plate and the horizontal segment of L shape support, and proximity switch is kept away from to the tablet this moment, and when wire rope was cut, the effect of spring was down drawn proximity switch with the tablet, and proximity switch senses the tablet and sends inductive signal to the treater, and the treater receives this inductive signal after-control audible-visual annunciator and carries out local warning to remind the sales force to pay attention to.
