Description

Technical Field

[0001] The utility model relates to the technical field of mask locking devices, in particular to a locking mechanism for an LED mask. Background Art

[0002] An LED mask is a decorative or functional mask made using light-emitting diode technology that can be used in a variety of occasions and for a variety of purposes. For example, LED masks are often used as fashion accessories at parties, nightclubs, music festivals, and other entertainment events. They are usually designed with various patterns and colors, and the lighting effects can change according to the music or the user's movements. In certain work environments, such as construction sites or night operations, LED masks can increase workers' visibility and improve safety. In medical applications, some LED masks are used for light therapy, such as treating skin problems or relieving pain.

[0003] Most existing LED masks use a binding mechanism as the locking mechanism, which uses a tether to wrap and knot the LED mask to fix it to the user's face. This design has many defects. Different people have different forehead widths, and the length of the tether needs to be selected according to needs, which is relatively cumbersome. In addition, it is difficult to ensure complete fixation for a long time by simply binding the tether. The user's slight shaking or swinging movements may cause the tether to loosen. Utility Model Content

[0004] The purpose of the present utility model is to provide a locking mechanism for an LED mask to solve the problems raised in the above background technology.

[0005] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a locking mechanism for an LED mask, comprising a central mask, a supporting plate on the left side of the central mask, and a central layer provided in the middle of the supporting plate, a bottom column installed inside the central layer, inlaid blocks installed at both ends of the bottom column, and an end fixing seat installed at the upper end of the inlaid block, a rewinding spring installed on the surface of the bottom column, an engaging plate installed on the right side of the central mask, and a receiving layer provided inside the engaging plate, and a bottom plate installed inside the receiving layer.

[0006] Preferably, an outer ring is assembled on the outer side of the rewind spring, and a fixing block is assembled on the surface of the outer ring, and an insertion opening is provided on the surface of the fixing block.

[0007] Preferably, an external post is assembled on the insertion port, and the surface of the external post is connected to the tether belt, and a locking buckle is assembled at the end of the tether belt.

[0008] Preferably, a fitting block is assembled on the surface of the bottom plate, and a pressure spring is assembled on the upper end of the fitting block, and a pressing block is mounted on the upper end of the pressure spring.

[0009] Preferably, a return spring is installed on the side of the fitting block, and a buckle block is installed on the upper end of the return spring, and a movable column is inserted in the middle of the buckle block.

[0010] Preferably, a locking port is provided on the surface of the locking buckle, and the upper end of the return spring is assembled and connected to the pressing plate.

[0011] Compared with the prior art, the beneficial effects of the present invention are:

[0012] 1. Compared with the locking mechanism of other LED masks, this device is equipped with a rewinding roller on one side that is fixedly connected by a rewinding spring, and a tether is assembled on the rewinding roller. This design provides a retraction and tightening effect for the tether. When the user pulls the front plug outward and extends the tether outward, the internal rewinding roller rotates, giving the rewinding spring a retraction force to pull the tether, thereby ensuring that the tether is taut during use and will not loosen.

[0013] 2. In addition, the other end of the device is equipped with a locking mechanism, which, combined with the automatic locking effect, makes the device easy to use. The device has a lightweight structure and is easy to perform subsequent maintenance and disassembly. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0020] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0021] See also Figures 1 to 5 , the utility model provides a technical solution:

[0022] refer to Figure 1 The main body is a central mask 1, a bearing plate 2 on the left side of the central mask 1, the bearing plate 2 is assembled on the left surface of the central mask 1, and a central layer is provided in the middle of the bearing plate 2, a bottom column 12 is installed inside the central layer, and mosaic blocks 7 are installed at both ends of the bottom column 12. The mosaic blocks 7 are assembled on the inner surface of the central layer to fix the bottom column 12, and the upper end of the mosaic block 7 is installed with an end fixing seat 8. A rewind spring 4 is assembled on the surface of the bottom column 12, and an engaging plate 3 is assembled on the right side of the central mask 1, and a receiving layer is provided inside the engaging plate 3, and a bottom plate is assembled inside the receiving layer;

[0023] refer to Figure 2 、 3 The main body is a rewind spring 4, an external ring 5 is assembled on the outside of the rewind spring 4, and the middle position of the rewind spring 4 is welded to the surface of the outer ring. When the external ring 5 starts to rotate, it will drive the rewind spring 4 in the middle part to twist, so as to give the rewind spring 4 the same rewinding force to drive the external ring 5 to rotate to the original angle, and a fixing block 11 is assembled on the surface of the external ring 5, and an insertion opening is provided on the surface of the fixing block 11, and an external column 10 is assembled on the insertion opening, and a tether belt 6 is connected to the surface of the external column 10, and a locking buckle 9 is assembled at the end of the tether belt 6. The locking buckle 9 is assembled on the outside of the bearing plate 2, and a connection port is provided at its connection point, and the size of the locking buckle 9 is designed to exceed the size of the connection port to prevent the rewind force from pulling the locking buckle 9 into the inside of the bearing plate 2;

[0024] refer to Figure 4 、 5 The main body is a bottom plate, the surface of the bottom plate is assembled with a fitting block, and the upper end of the fitting block is assembled with a pressure spring 14, and a pressure block 13 is installed on the upper end of the pressure spring 14. A return spring 16 is installed on the side of the fitting block, and a snap block 17 is installed on the upper end of the snap block 16. A movable column 15 is inserted in the middle of the snap block 17. A locking port is provided on the surface of the locking buckle 9, and a connecting pressing plate 18 is assembled on the upper end of the snap block 16. An engaging extension plate is provided on the outer side of the connecting plate, and the bottom is connected to the surface of the snap block 17. In addition, the bottom of the snap block 17 is also connected to the return spring 16.

[0025] In actual use, first place the LED mask on the user's face and align it with various positions. After completion, stretch the locking buckle 9 and press the locking buckle 9 toward the connection port of the engaging plate 3. As the locking buckle 9 contacts the pressing block 13, the pressing block 13 is pushed inward, and the pressure spring 14 at its bottom moves downward. The locking buckle 9 replaces the position of the pressing block 13. When the locking port on the surface contacts the front end of the buckle block 17, the return spring 16 at the bottom will push the buckle block 17 to rotate along the movable column 15 to press the end against the locking port to achieve the locking operation. When it needs to be opened, just press the connecting pressing plate 18 at the upper end of the buckle block 17 downward to make the return spring 16 move downward and the end move out. In addition, an external extension plate is provided on the outside of the connecting pressing plate 18 to prevent the pressing of the connecting pressing plate 18 from exceeding the limit of the return spring 16.
