Description

Technical Field

[0001] The utility model relates to the technical field of light box locks, in particular to a new type of lock for a light box. Background Art

[0002] A light box is a viewing light box (illuminator) used for viewing X-rays (negatives). It's typically made of film, preferably PC. To attract attention and achieve publicity and promotional effects, light boxes are increasingly used, particularly in densely populated public places like airports, subways, and plazas. They often feature a lock to secure the panel to the main body of the light box.

[0003] Most existing light box locks only have a single unlocking method, namely key unlocking. In actual use, if the key breaks inside the keyhole or the key is lost, it is difficult for the operator to open the lock again. Subsequently, professional locksmiths are required to unlock the lock. The actual use of the device has certain limitations. For this reason, we propose a new type of lock for light boxes. Utility Model Content

[0005] In view of the above problems and / or the problems existing in existing light box locks, the present utility model is proposed.

[0006] Therefore, the purpose of the present invention is to provide a new type of lock for a light box, in which a second strong magnet is set to attract the first strong magnet inside, and the second strong magnet is controlled to drive the first strong magnet inside and the locking block to move. When the key insert plate is lost or damaged and breaks in the key hole, the locking block can be driven to move to both sides by the second strong magnet, thereby releasing the lock on the locking rod. Compared with the existing single key unlocking, the present invention has two unlocking methods: key unlocking and magnet unlocking. When the key is lost or damaged, the lock can also be quickly unlocked by the strong magnet, which enhances the practicality of the device.

[0007] In order to solve the above technical problems, according to one aspect of the present invention, the present invention provides the following technical solutions:

[0024] In order to make the purpose, technical solutions and advantages of the present invention more clear, the embodiments of the present invention will be described in further detail below with reference to the accompanying drawings.

[0025] The utility model provides a new type of lock for a light box, in which a second strong magnet is provided to attract the first strong magnet inside, and the first strong magnet inside and the locking block are driven to move by controlling the second strong magnet. When the key inserting plate is lost or damaged and breaks in the key hole, the locking block can be driven to move to both sides by the second strong magnet, thereby releasing the lock of the locking rod. Compared with the existing single key unlocking, the utility model has two unlocking methods: key unlocking and magnet unlocking. When the key is lost or damaged, the lock can also be quickly unlocked by the strong magnet, thereby enhancing the practicality of the device.

[0026] Figure 1-Figure 3 The following is a schematic diagram of a structure of a new type of lock for a light box according to the present invention. Figure 1-Figure 3 In this embodiment, a new type of lock for a light box has a main body including a locking assembly 100 and a locking rod assembly 200.

[0027] The locking assembly 100 includes two vertical plates 110 vertically arranged in the light box body, an elastic member 120 arranged on the inner side of the two vertical plates 110 and a locking block 130 arranged on the inner side of the elastic member 120. A telescopic rod is arranged inside the elastic member 120, and the two ends of the telescopic rod are fixedly connected to the vertical plates 110 and the locking block 130 respectively. A placement groove is provided at the front end of the locking block 130, and a first strong magnet 131 is provided in the placement groove. A second strong magnet 132 is provided at the front end of the first strong magnet 131, and the first strong magnet 131 and the second strong magnet 132 are opposite magnets. Preferably, in this embodiment, a mounting plate 111 is vertically fixed to the lower end of the vertical plate 110, and a bolt 112 is provided on the mounting plate 111. The vertical plate 110 is installed inside the light box body under the action of the mounting plate 111 and the bolt 112. The operator can remove the vertical plate 110 by removing the bolt 112 later, so as to disassemble and replace the locking assembly 100. A mounting hole 113 is provided on the inner side of the vertical plate 110, and a connecting block 121 is provided on the outer side of the elastic member 120. The connecting block 121 is threadedly connected to the vertical plate 110. The elastic member 120 and the locking block 130 are threadedly installed on the inner side of the vertical plate 110 under the action of the connecting block 121. The operator can remove it by rotating the connecting block 121, and then remove the elastic member 120 and the locking block 130, so as to disassemble and replace them.

[0028] The locking rod assembly 200 includes a locking rod body 210 vertically installed on the inner side of the light box panel, a card slot 220 opened on the outer wall opposite to the locking rod body 210, and a key inserting plate 230 inserted in the locking rod body 210, and the locking block 130 is clamped in the card slot 220. Preferably, in this embodiment, the end of the locking rod assembly 200 is provided with an ejection spring 201 located inside the light box body, and the front end of the ejection spring 201 is provided with an ejection plate 202. The ejection spring 201 and the ejection plate 202 provided at the end of the locking rod assembly 200 can eject the light box panel when the key insert plate 230 is inserted into the locking rod body 210 to unlock it. The front end of the outer wall of the locking rod body 210 is provided with an external thread 211, and a threaded through hole is provided on the light box panel. The locking rod body 210 is threadedly connected to the light box panel, and a limiting plate 212 is fixed on the outer wall of the locking rod body 210. The locking rod body 210 is threadedly installed on the light box panel under the action of the external thread 211 and the threaded through hole. It can be removed by rotating the locking rod body 210 later for disassembly and replacement. The limiting plate 212 provided on the outer wall of the locking rod body 210 plays a limiting role on the locking rod body 210 during the installation process.

[0029] Combine Figure 1-Figure 3 The new lock for a light box in this embodiment is specifically used as follows: when the light box panel is closed, the locking rod body 210 applies an outward force to the locking block 130, so that the elastic member 120 on the outside is compressed. When the light box panel and the light box body are fitted together, the locking block 130 is clamped in the locking groove 220 of the locking rod body 210 under the elastic action of the elastic member 120. At this time, the locking assembly 100 locks the locking rod assembly 200, and then locks the light box panel and the light box body together. Later, the locking block 130 can be released from the locking rod body by inserting the key inserting plate 230 into the locking rod body 210. 210 is locked, thereby achieving the purpose of unlocking. When the key inserting plate 230 is lost or damaged, the second strong magnet 132 is provided to attract the first strong magnet 131 inside, and then the second strong magnet 132 is controlled to drive the first strong magnet 131 inside and the locking block 130 to move to both sides, thereby releasing the locking block 130 from locking the locking rod body 210. Compared with the existing single key unlocking, the utility model has two unlocking methods: key unlocking and magnet unlocking. When the key is lost or damaged, the strong magnet can also be used to quickly unlock, thereby enhancing the practicality of the device.

[0030] While the present invention has been described above with reference to specific embodiments, various modifications may be made and equivalent components may be substituted without departing from the scope of the present invention. In particular, as long as no structural conflicts exist, the various features of the embodiments disclosed herein may be combined with one another in any manner, and the omission of an exhaustive description of these combinations in this specification is solely for the sake of space and resource conservation. Therefore, the present invention is not limited to the specific embodiments disclosed herein, but encompasses all technical solutions within the scope of the claims.
