Technical Field
[0001] This utility model relates to the field of water cup sleeve technology, and in particular to a water cup sleeve with a combination lock. Background Technology
[0002] Most existing cup sleeves are used to protect and seal cups. Some products have added latches or combination locks to prevent the cup sleeve lid from accidentally falling off or being opened at will. These cup sleeves are usually opened and closed by mechanical latches, simple lock cylinders or external combination locks, which can meet security requirements to a certain extent and are widely used in the market.
[0003] However, the existing technologies mentioned above still have shortcomings: their combination locks are mostly simple mechanical structures with a single lock tongue reset method. Users need to repeatedly turn or adjust the lock during the unlocking or locking process, which is cumbersome and cannot achieve quick and convenient opening and closing. When users need to frequently open and close water cups when they are out or in daily use, this design not only affects efficiency but also reduces the user experience. Utility Model Content

[0014] The technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.
[0015] like Figure 1 As shown, a water cup sleeve with a combination lock includes a cup sleeve body 21, a cup sleeve cover 22 attached to the upper surface of the cup sleeve body 21, a zipper 26 provided on the outside of the cup sleeve cover 22 and the cup sleeve body 21, a pull head 23 engaged with the zipper 26, a connecting rope 25 fixedly connected to the outside of the pull head 23, a locking ring 10 provided at the end of the connecting rope 25 away from the pull head 23, and a combination lock body 24 provided inside the cup sleeve cover 22. Specifically, in this embodiment, the cup sleeve cover 22 is attached to the upper surface of the cup sleeve body 21. By tightening the pull head 23 and the zipper 26, the upper port of the cup sleeve body 21 can be closed. When the locking ring 10 is inserted into the designated position inside the combination lock body 24, the locking ring 10 is restricted by the locking state of the combination lock body 24, thereby restricting the relative separation of the cup sleeve cover 22 and the cup sleeve body 21, and realizing the locking of the cup sleeve.
[0016] like Figures 2 to 5As shown, the combination lock body 24 includes a lock shell 1. Inside the lock shell 1 are a fingerprint recognition module 2, a motor 3, a controller module 4, a battery 5, a linkage plate 6, and a lock pin 7. The panel of the lock shell 1 has a fingerprint recognition window 11, a lock hole 12, and a charging port 17. The charging port 17 is used to charge the battery 5. The fingerprint recognition module 2 is located at the fingerprint recognition window 11. The controller module 4 is electrically connected to the battery 5, the motor 3, and the fingerprint recognition module 2. An eccentric guide wheel 31 is fixedly connected to the power output shaft of the motor 3. A shaft 32 is provided on the eccentric guide wheel 31. The linkage plate 6 has a sliding hole 61 that cooperates with the shaft 32. The lock pin 7 is connected to the linkage plate 6. A lock tongue 71 is fixedly connected to the lock pin 7. A support plate 13 is provided inside the lock shell 1. A first return spring (not shown in the figure) is provided between the support plate 13 and the lock pin 7. The first return spring drives the lock pin 7 to return to its original position, causing the lock tongue 71 to extend out of the lock hole 12. Furthermore, the motor 3 is placed horizontally on the lower side of the support plate 13, the linkage plate 6 is "7" shaped and placed sideways inside the lock housing 1, the locking pin 7 is connected to the horizontal plate 62 of the linkage plate 6, and the sliding hole 61 is set on the vertical plate 63 of the linkage plate 6; the support plate 13 is provided with a positioning pin 14, the locking pin 7 is a hollow structure, one end of the first reset spring is sleeved on the positioning pin 14, and the other end is fixed inside the locking pin 7.
[0017] When in use, a finger is pressed on the fingerprint recognition module 2. After receiving the signal, the controller module 4 controls the motor 3 to rotate. The motor 3 drives the eccentric guide wheel 31 to rotate. At this time, the shaft 32 rotates and pushes the sliding hole 61 to make the linkage plate 6 move accordingly. The rotation of the eccentric guide wheel 31 is converted into the up and down movement of the linkage plate 6. The linkage plate 6 drives the locking pin 7 to move downward and compress the first return spring. In this way, the locking tongue 71 disengages downward from the external locking ring 10, which can open the external locking ring 10 from the lock case 1. After the motor 3 rotates one revolution, it stops. The first return spring returns to its original deformation and drives the locking pin 7 to move upward and reset. At this time, the locking tongue 71 extends out from the lock hole 12.
[0018] The lock housing 1 is also provided with a base plate, and threaded posts (not shown in the attached figure) are provided at the four corners inside the lock housing 1. Bolt holes corresponding to the threaded posts are provided around the base plate. The base plate is screwed and fixed to the lock housing 1 by bolts in the bolt holes and threaded posts.
[0019] It also includes a locking spring 9, and a positioning pin 16 is provided on each side of the lock hole 12. The locking spring 9 is sleeved on the positioning pin 16 and can slide up and down along the positioning pin 16. A second return spring (not shown in the figure) is sleeved on the positioning pin 16. One end of the second return spring abuts against the locking spring 9 and the other end abuts against the base plate. When the lock tongue 71 is disengaged from the external lock ring 10 downwards, the second return spring drives the locking spring 9 to move towards the lock hole 12 and pops the external lock ring 10 out of the lock case 1.
[0020] In one embodiment, the locking pin 7, the locking tongue 71, and the linkage plate 6 are integrally formed. The sliding hole 61 is a semi-circular hole with an opening facing downwards, and the radius of the arc edge of the sliding hole 61 matches the rotation radius of the shaft 32. A vertical clearance groove 611 is provided on one side of the sliding hole 61. When the locking tongue 71 extends out of the lock hole 12, the shaft 32 is located on one side of the sliding hole 61 and below the clearance groove 611. A limiting plate 19 is provided inside the lock housing 1, and the limiting plate 19 is located on the upper side of the linkage plate 6. When motor 3 rotates clockwise, shaft 32 is located on the right side of sliding hole 61. As motor 3 rotates clockwise, shaft 32 follows suit and presses downwards against the straight lower edge of sliding hole 61. At this time, linkage plate 6 moves downwards. When motor 3 rotates 90°, locking tongue 71 retracts from locking hole 12. As motor 3 continues to rotate, the first return spring drives linkage plate 6 to return to its original position. When motor 3 rotates 180°, the upper side of linkage plate 6 contacts limiting plate 19, thus limiting plate 19 prevents linkage plate 6 from continuing to move upwards. At this time, the latch 71 extends out from the lock hole 12; the motor 3 continues to rotate, and the shaft 32 rotates along the arc edge of the sliding hole 61 to the right side of the sliding hole 61; when it is necessary to lock the external locking ring 10 onto the lock housing 1, the locking ring 10 is inserted into the lock hole 12 and the edge of the locking ring 10 presses down on the latch 71. At this time, the linkage plate 6 moves downward, and the shaft 32 enters the clearance groove 611. Then, the first return spring drives the linkage plate to return to its original position, and the latch 71 pops out from the locking ring 10, thus locking the external locking ring 10 onto the lock housing 1. When the motor 3 rotates counterclockwise, the shaft 32 is located at the leftmost side of the sliding hole 61, and the movement process is the same as described above.
[0021] In another embodiment, the sliding hole 61 is an elongated hole arranged laterally along the width of the linkage plate 6. The clearance groove 611 is located in the middle of the upper edge of the sliding hole 61. When the latch 71 extends out of the lock hole 12, the shaft 32 is located in the middle of the sliding hole 61, that is, below the clearance groove 611. When the motor 3 rotates, the shaft 32 rotates and presses the lower edge of the sliding hole 61 downward. At this time, the linkage plate 6 moves downward, and the latch 71 retracts downward to press the first return spring. When the shaft 32 rotates 180°, the latch 71 retracts completely from the lock hole 12, and the external lock ring 10 disengages. The motor 3 continues to rotate, and the shaft 32 rotates and presses the upper edge of the sliding hole 61 upward. After the motor 3 rotates one revolution, the shaft 32 returns to the middle of the sliding hole 61. At this time, the first return spring drives the latch 71 to extend out of the lock hole 12. When it is necessary to lock the external locking ring 10 onto the lock housing 1, the locking ring 10 is inserted into the lock hole 12 and the edge of the locking ring 10 presses down on the locking tongue 71. At this time, the linkage plate 6 moves downward and the shaft 32 enters the clearance groove 611. Then, the first return spring drives the linkage plate to reset, and the locking tongue 71 pops out from the locking ring 10, thus locking the external locking ring 10 onto the lock housing 1.
[0022] In one embodiment, the locking pin 7 is movably connected to the linkage plate 6. Specifically, a through hole 64 is provided on the horizontal plate 62 of the linkage plate 6, and a retaining edge 72 is provided on the lower side of the locking pin 7. The locking pin 7 passes through the through hole 64 and the retaining edge 72 is engaged with the lower side of the linkage plate 6. The sliding hole 61 is an elongated hole arranged horizontally along the width of the linkage plate 6. When the locking tongue 71 extends out of the locking hole 12, the shaft 32 is located in the middle of the sliding hole 61. When motor 3 rotates, shaft 32 rotates accordingly and presses downward against the lower edge of sliding hole 61. At this time, linkage plate 6 moves downward, and latch 71 retracts downward, pressing the first return spring. When shaft 32 rotates 180°, latch 71 retracts completely from lock hole 12, and external lock ring 10 disengages. Motor 3 continues to rotate, shaft 32 rotates accordingly and presses upward against the upper edge of sliding hole 61. After motor 3 rotates one revolution, shaft 32 returns to its original position and stops at the middle of sliding hole 61. At this time, the first return spring drives latch 71 to extend out of lock hole 12. When it is necessary to lock external lock ring 10 onto lock housing 1, lock ring 10 is inserted into lock hole 12, and the edge of lock ring 10 presses downward against latch 71. At this time, linkage plate 6 remains stationary, and the first return spring is compressed. Then, the first return spring drives latch 71 to return to its original position and extend out of lock hole 12, thus locking external lock ring 10 onto lock housing 1.
[0023] Working principle: When using the water cup sleeve with a combination lock, the pull head 23 is connected to the locking ring 10 via the connecting rope 25. To lock the water cup sleeve, pull the pull head 23 to the closed state, aligning the locking ring 10 with the lock hole 12 and pressing it inward. The edge of the locking ring 10 pushes the latch spring 9 into the lock housing 1 and presses the bolt 71 downward. When the keyhole on the locking ring 10 is aligned with the bolt 71, the first return spring drives the bolt 71 upward and into the keyhole, thus locking the water cup sleeve. To unlock, place your finger on the fingerprint recognition module 2. The fingerprint recognition module 2 recognizes the fingerprint and sends a signal back to the controller module 4. After successful fingerprint verification, the controller module 4 controls the motor 3 to rotate. The shaft 32 on the eccentric guide wheel 31, in conjunction with the sliding hole 61, drives the linkage plate 6 and the locking pin 7 downward, causing the bolt 71 to retract into the lock hole 12. The second return spring drives the latch spring 9 to pop out the locking ring 10, thus unlocking the water cup sleeve.
[0024] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
