[0020] like Figures 1 to 10 As shown, the embodiment of the present invention provides an elastic locking device for a flip-top jewelry box, comprising a rotating mechanism 1 and a box cover 2, wherein the rotating mechanism 1 is mounted at the bottom of the box cover 2, a box body 3 is arranged below the box cover 2, the rotating mechanism 1 is rotatably mounted on the top of the box body 3, a wedge block 4 is fixedly arranged on the other side of the bottom of the box cover 2, a swing-type locking mechanism 5 is rotatably mounted on the front of the box body 3, the wedge block 4 is adapted to the swing-type locking mechanism 5, a lubricating portion 7 is sleeved on the outer side of the swing-type locking mechanism 5, and the box cover 2 is flipped and installed by the rotating mechanism 1 Installed on the top of the box body 3, the swing locking mechanism 5 includes an intermediate shaft 51, a toggle plate 52, a second wedge block 53, a second torsion spring 54 and a slot 55. The intermediate shaft 51 is rotatably sleeved on the front side of the box body 3. The toggle plate 52 and the second wedge block 53 are both fixedly sleeved on the outer surface of the intermediate shaft 51. The lubrication part 7 includes a collar 71, a storage groove 72 and an annular groove 73. The annular groove 73 is provided on the inner wall of the collar 71. The storage groove 72 is symmetrically provided on the inner wall of the collar 71 and is connected to the annular groove 73. Lubricating oil is stored in the storage groove 72.

[0021] Embodiment 1: When in use, flip the box cover 2 so that the box cover 2 rotates around the rotating shaft 112 in the rotating mechanism 1, the torsion spring 113 is compressed to store elastic potential energy, and the box cover 2 is flipped and gradually merged with the box body 3, and the wedge block 1 4 is driven to move downward and inserted into the assembly groove 8, and during the insertion process, the wedge block 1 4 pushes the wedge block 2 53 in the swing-type locking mechanism 5, and as the wedge block 2 53 is squeezed and pushed away, the swing-type locking mechanism 5 deflects, the torsion spring 2 54 is compressed to store elastic potential energy, and after the wedge block 2 53 is staggered from the wedge block 1 4, the torsion spring 2 54 is elastically reset, and the wedge block 2 53 is driven to swing and reset, so that the wedge block 1 4 and the wedge block 2 53 are engaged to complete the locking, and when it is necessary to unlock, the finger extends to the protective ring 6 The toggle plate 52 is pushed, so that the toggle plate 52 drives the intermediate shaft 51 to rotate, compresses the torsion spring 2 54, and moves the wedge block 2 53 out of the wedge block 1 4 to release the bite. At this time, the torsion spring 1 13 in the rotating mechanism 1 is elastically reset, and drives the box cover 2 to flip upward, and automatically opens the jewelry box. In the process of the intermediate shaft 51 in the swing-type locking mechanism 5 rotating, the intermediate shaft 51 rotates inside the lubrication part 7. When the intermediate shaft 51 rotates, the lubricating oil in the storage groove 72 is evenly coated on the outer surface of the intermediate shaft 51, lubricating the contact surface between the intermediate shaft 51 and the ring 71, and realizing swing lubrication; when the front of the jewelry box is bumped and pressed, the swing-type locking mechanism 5 is not affected, and the jewelry box remains locked.

[0022] Firstly, by utilizing the cooperation of the swing locking mechanism 5 and the rotating mechanism 1, the box cover 2 is pressed down to realize the automatic pushing of the wedge block 4 on the swing locking mechanism 5, and the automatic locking is completed by cooperating with the twisting and resetting of the swing locking mechanism 5. When unlocking is needed, the finger is inserted into the protective ring 6 and the toggle plate 52 is pushed to deflect, thereby driving the swing locking mechanism 5 to deflect and unlock. In actual application and use, the automatic opening of the jewelry box caused by frontal collision and pressure can be effectively avoided, the locking stability is provided, and it is ensured that the jewelry box can be opened only by accurate manual operation. While having the quick locking and opening of the jewelry box, it also has the safety of use, avoids accidental opening, and has a good comprehensive use effect.

[0023] In addition, by reusing the swing locking and opening states of the swing locking mechanism 5, in cooperation with the lubrication part 7 sleeved on the outside of the intermediate shaft 51, the lubricating oil is fully stored in the lubrication part 7 by utilizing the annular groove 73 and the storage groove 72 provided in the lubrication part 7, and the outer side surface of the intermediate shaft 51 in the swing locking is fully lubricated, thereby ensuring that the intermediate shaft 51 in the locking mechanism maintains rotation after lubrication, reducing the influence of friction on the locking mechanism, reducing the occurrence of friction gaps, avoiding activity noise after loosening, and increasing the service life of the swing locking mechanism 5 in the jewelry box. While maintaining the stability of the jewelry box locking, it also has the advantage of a long service life.

[0024] Embodiment 2: When locking, while pressing down the pulling block 131 in the elastic component 13, as the pushing of the pulling block 131 moves downward along the chute 10, the rigid rope 134 is pulled, so that the rigid rope 134 passing through the internal cavity 11 pulls the bottom plate 132 downward, compresses the spring 133 while pulling the sponge pad 12 downward, causing the jewelry inserted on the sponge pad 12 to move downward and be completely inside the box body 3. When the lock is pressed and locked, the pulling block 131 in the elastic component 13 is released, the spring 133 elastically resets, and pushes the sponge pad 12 to move upward in the box body 3, driving the outer sealing ring 14 to move upward and move to the contact area between the box cover 2 and the box body 3, completing the surrounding seal, further isolating the air inside and outside the jewelry box. When the jewelry box drops, collides and vibrates, the sponge pad 12 and the bottom plate 132 inside the box body 3 vibrate along the top of the spring 133, and through the friction of the sponge pad 12 along the inner wall of the box body 3, the elastic potential energy of the spring 133 is gradually absorbed, completing the vibration buffering under damping treatment.

[0025] First of all, by using the elastic component 13 added inside the box body 3, the sponge pad 12 in the box body 3 is pulled downward before the jewelry box is locked and automatically moves upward after the box cover 2 is locked. Using the sealing ring 14 outside the sponge pad 12, it moves to the joint of the box cover 2 and the box body 3 to complete the enhanced seal, isolate the internal and external air, and reduce the oxidation and pollution of the internal items.

[0026] In addition, by using the elastic effect of the elastic component 13 again, combined with the friction damping between the sponge pad 12 and the inner wall of the box body 3, when the jewelry is placed inside the jewelry box and it falls, on the one hand, it prevents the jewelry box from opening, and on the other hand, the spring 133 cooperates with the sponge pad 12 to achieve elastic buffering under damping, further protecting the jewelry pieces in the jewelry box. Through maintaining stable locking and internal elastic buffering, a safe and reliable locking and storage process is comprehensively realized, and the use effect is good.

[0027] Among them, the rotating mechanism 1 includes a connecting column 111, a rotating shaft 112 and a first torsion spring 113.

[0028] The rotating mechanism 1 adapts to the connection between the box cover 2 and the box body 3 to achieve a flipping action, and with the elasticity of the first torsion spring 113, it is convenient to automatically open and open the box body 3.

[0029] Among them, an adaptation groove 9 is opened at the top of the box body 3, the rotating shaft 112 is located in the adaptation groove 9, and both ends are rotatably sleeved inside the box body 3. An assembly groove 8 is opened at the top of the box body 3, and a protective ring 6 is fixedly connected to the front of the box body 3.

[0030] The adapting groove 9 is adapted to the installation connection of the rotating mechanism 1, and the assembling groove 8 is adapted to the insertion of the wedge block 1 4 and provides a swing space for the wedge block 2 53 to maintain a stable locking action.

[0031] Among them, the toggle plate 52 is located on the outside of the box body 3 and in the protective ring 6, the wedge block 53 is located in the assembly groove 8, the torsion spring 54 is fixedly connected between the toggle plate 52 and the box body 3, the card slot 55 is opened on the side of the wedge block 53, the top left side of the wedge block 53 is provided with an inclined portion 1, the bottom of the wedge block 1 is provided with an inclined portion 2, and the side of the wedge block 1 is provided with a connecting groove, and the wedge block 14 and the wedge block 2 53 are movably locked.

[0032] By utilizing the toggle effect of the toggle plate 52, the deflection of the swing-type locking mechanism 5 is controlled to complete the unlocking operation. The elasticity of the torsion spring 2 54 facilitates the automatic reset of the wedge block 2 53 after deflection, thereby completing the automatic locking. By utilizing the shape and structure of the wedge block 1 4 and the wedge block 2 53, the bite process is completed to achieve locking.

[0033] A sponge pad 12 is provided inside the box body 3 , a sealing ring 14 is nested on the top of the outer side of the sponge pad 12 , an elastic component 13 is fixedly connected to the bottom of the sponge pad 12 , and one end of the elastic component 13 is slidably mounted on the front of the box body 3 .

[0034] The sponge pad 12 ensures stable placement of the jewelry piece and cooperates with the elastic component 13 to absorb vibration energy and provide buffering protection with a damping effect.

[0035] Among them, a slide groove 10 is opened on the front of the box body 3, and an internal cavity 11 is opened inside the box body 3. The upper end of the internal cavity 11 is connected to the slide groove 10, and the lower end is connected to the inside of the box body 3. The elastic component 13 includes a pulling block 131, a bottom plate 132, a spring 133 and a rigid rope 134. The bottom plate 132 is fixedly connected to the bottom of the sponge pad 12, one end of the spring 133 is fixed to the bottom surface of the bottom plate 132, and the other end is fixed to the bottom of the inner cavity of the box body 3. The pulling block 131 is "T-shaped" and is slidably sleeved in the slide groove 10. One end of the rigid rope 134 is fixedly connected to the bottom surface of the bottom plate 132, and the other end passes through the interior of the internal cavity 11, extends into the slide groove 10, and is fixedly connected to the pulling block 131.

[0036] By utilizing the elastic component 13, in coordination with the slide groove 10 and the internal cavity 11, the position of the sponge pad 12 can be actively controlled, and the elastic reset effect can be utilized to adjust the position of the sponge pad 12 and the sealing ring 14 when opening and closing the cover, thereby preventing the sponge pad 12 that is too high from affecting the closure of the box cover 2, and dynamically achieving seam sealing.

[0037] The working principle and use process of the present invention are as follows: when in use, the box cover 2 is flipped so that the box cover 2 rotates around the rotating shaft 112 in the rotating mechanism 1, the torsion spring 113 is compressed to store elastic potential energy, and the box cover 2 is flipped and gradually merged with the box body 3, and the wedge block 114 is driven to move downward and inserted into the assembly groove 8, and during the insertion process, the wedge block 114 pushes the wedge block 2 53 in the swing-type locking mechanism 5, and as the wedge block 2 53 is squeezed and pushed away, the swing-type locking mechanism 5 deflects, the torsion spring 2 54 is compressed to store elastic potential energy, and after the wedge block 2 53 is staggered from the wedge block 114, the torsion spring 2 54 is elastically reset and drives the wedge block 2 53 to move downward. 3 is swung back to reset, so that wedge block 1 4 and wedge block 2 53 are engaged to complete the locking. When unlocking is required, the finger extends into the protective ring 6 and pushes the toggle plate 52, so that the toggle plate 52 drives the intermediate shaft 51 to rotate, compresses the torsion spring 2 54, and makes the wedge block 2 53 move out of the wedge block 1 4 to release the engagement. At this time, the torsion spring 1 13 in the rotating mechanism 1 is elastically reset and drives the box cover 2 to flip upward to automatically open the jewelry box. In the process of the intermediate shaft 51 in the swing locking mechanism 5 rotating, the intermediate shaft 51 rotates inside the lubrication part 7, and the lubricating oil in the storage groove 72 is evenly coated when the intermediate shaft 51 rotates. The outer surface of the intermediate shaft 51 is arranged to lubricate the contact surface between the intermediate shaft 51 and the sleeve ring 71, so as to realize swing lubrication; when the front of the jewelry box is bumped and pressed, the swing locking mechanism 5 is not affected, and the jewelry box remains locked; when locking, the pulling block 131 in the elastic component 13 is pressed down at the same time, and as the pulling block 131 is pushed down along the slide groove 10, the rigid rope 134 is pulled, so that the rigid rope 134 passing through the inner cavity 11 pulls the bottom plate 132 to move downward, and the spring 133 is compressed while pulling the sponge pad 12 downward, so that the jewelry inserted on the sponge pad 12 moves downward and is completely locked. It is inside the box body 3. After pressing and locking, the pulling block 131 in the elastic component 13 is released, the spring 133 is elastically reset, and pushes the sponge pad 12 to move upward in the box body 3, driving the outer sealing ring 14 to move upward and move to the contact area between the box cover 2 and the box body 3, completing the surrounding seal, and further isolating the air inside and outside the jewelry box. When the jewelry box falls, collides and vibrates, the sponge pad 12 and the bottom plate 132 inside the box body 3 vibrate along the top of the spring 133, and the sponge pad 12 rubs along the inner wall of the box body 3, gradually absorbing the elastic potential energy of the spring 133, completing the vibration buffering under the damping treatment.

[0038] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
