Description

Gold jewelry showcase is robbed in theftproof

Technical Field

The invention relates to a counter for displaying jewelry gold, in particular to an anti-robbery counter.

Background

Due to the development of social economy, the population density of the urban districts is quite high, and therefore, the frequent transmission of events such as robbery cases and the like is caused. Although some jewelry stores, gold shops, museums or financial institutions are provided with security devices, the devices can only send out an alarm or automatically alarm in a detection or starting mode when robbers invade, valuable articles or money cannot be hidden in time, and therefore financial loss and personal injury and death are caused to some extent when robbers happen.

Disclosure of Invention

The invention aims to provide a jewelry display cabinet which can instantly hide jewelry when robbery happens.

In order to solve the technical problem, the anti-theft and anti-robbery gold and jewelry showcase comprises a showcase body, wherein glass is arranged above the showcase body, a jewelry bearing platform is arranged below the glass, a jewelry placing device is placed on the jewelry bearing platform, an opening is formed in the jewelry bearing platform, a movable plate is arranged at the opening, an opening and closing mechanism capable of enabling the movable plate to be rapidly opened and closed is arranged below the movable plate, an exciting device is connected to the opening and closing mechanism, and the jewelry placing device is connected with a pull-back device arranged in the showcase body.

In the technical scheme, when gangsters smash glass, the excitation device sends a signal, the opening and closing mechanism drives the movable plate at the opening to open, the pulling device drives the jewelry placing device to enter the cabinet body through the opening, and then the opening and closing mechanism drives the movable plate to return to close the opening, so that gangsters cannot rob the jewelry.

As an improvement, the movable plate is hinged to the object bearing platform, the opening and closing mechanism comprises a locking mechanism, a triggering mechanism and a return mechanism, the locking mechanism is connected with the sensor, the movable plate is fixed by the locking mechanism when the locking mechanism is not triggered, the movable plate is loosened when the locking mechanism is triggered, the triggering mechanism is fixedly installed on the position where the movable plate can be touched when the movable plate is overturned, and the return mechanism pushes the movable plate back to the original position when the triggering mechanism is triggered.

In the technical scheme, the movable plate is hinged to the object bearing table, after the sensor is excited, the sensor transmits a signal to the locking device, the locking device releases the movable plate, the movable plate overturns downwards around one end of the hinge under the action of gravity and touches the trigger mechanism, and after the trigger mechanism is excited, the return mechanism closes the movable plate.

As an improvement, the return mechanism comprises a supporting plate, one end of the supporting plate is hinged to the cabinet body, the other end of the supporting plate is hung on the trigger mechanism, and the supporting plate is connected with a supporting plate spring which can enable the supporting plate to push the movable plate to return.

In above-mentioned technical scheme, when trigger mechanism was not aroused, trigger mechanism caught the backup pad, and the backup pad spring has stored a large amount of potential energy, and trigger mechanism loosens the backup pad after arousing, and the backup pad is turned down around articulated department fast under the effect of backup pad spring, and the backup pad is beated on the fly leaf, makes the fly leaf return to close the opening. At the moment, the jewelry holding device is pulled into the cabinet body by the spring, the process is very fast, and the process can be completed between winks, so that a gangster cannot know what happens to make the jewelry invisible at once.

As an improvement, a trigger plate is fixedly arranged on the lower portion of the movable plate, the movable plate is in contact with the trigger mechanism through the trigger plate when being overturned, and the position of the trigger plate is matched with the positions of the support plate and the trigger mechanism, so that the support plate can reach the trigger plate when being excited, and the movable plate is pushed to return.

In the technical scheme, the trigger plate is arranged below the movable plate, so that the trigger device is triggered when the movable plate is turned over, the mechanism for the support plate to act is more stable and reliable, the range of the trigger mechanism touched by the movable plate can be expanded, and the trigger mechanism and the return device can be arranged at more proper positions in the cabinet body due to the design.

As an improvement, the locking mechanism secures and releases the movable plate by locking and releasing the firing plate. The locking mechanism can be arranged at the position where the lower end of the firing plate is located when the whole device is not excited, and the locking mechanism can be used for locking the movable plate more firmly and reliably.

As an improvement, trigger mechanism includes fixed mounting in the pivot of holding thing platform bottom and the couple that can revolute the pivot rotation, the crescent moon board that fixed connection and trigger plate position match on the couple, set up on the couple with couple vertically support arm, the support arm passes through the support arm spring coupling cabinet body. The fly leaf drives the trigger board when overturning and hits the crescent moon board, because the crescent moon board has certain radian, the crescent moon board can drive the couple rotation, and the backup pad drops from the couple, and the backup pad hits the trigger board under the effect of backup pad spring and promotes the trigger board to close the fly leaf. The trigger mechanism has simple, sensitive, stable and reliable structure, and can ensure that the movable plate can be opened and closed quickly at once.

As a refinement, the excitation device is a sensor arranged in the vicinity of the glass. The sensor can be a sound sensor, a vibration sensor and the like, the sensor senses that the glass of the jewelry cabinet body is smashed, a signal is transmitted to the opening and closing device, and the opening and closing device starts to act.

As an improvement, the pull-back device is a spring fixed on the cabinet body. The jewelry placing device on the object bearing table is connected to the spring, when the movable plate is closed, the spring is squeezed, and when the movable plate is opened, the jewelry placing device is pulled into the cabinet body by the spring.

The jewelry placing device is a piece of tablecloth, the tablecloth is arranged in two layers, a rigid strip matched with the length of an opening is arranged at the edge of the opening of the object bearing table between the two layers of tablecloth, and the spring is connected with the tablecloth through the rigid strip. The jewelry box is characterized in that a piece of table cloth is laid on the article bearing table, a small box for loading jewelry is fixed on the table cloth, the jewelry is fixedly placed in the small box, the spring is connected to the table cloth through a thin steel wire, and the jewelry can be smoothly packed up after being triggered. Further, the tablecloth is arranged into two layers, a rigid strip is arranged between the two layers of tablecloth and hidden between the two layers of tablecloth, the rigid strip is not easy to find, and the tablecloth can be more smoothly and rapidly collected after being triggered.

After the structure is adopted, the anti-theft and anti-robbery gold and jewelry showcase can transfer jewels into a firm cabinet body at the moment when robbery occurs, complete the jewel and gold collection at the moment when an unknown person cannot clearly see, and simultaneously close the movable plate for only a fraction of a second in the whole process, so that an unknown ruffian can take measures. The mechanism has the advantages of compact matching, rapid action, strong reliability, difficult failure and performance greatly superior to other similar products.
