DETAILED DESCRIPTION

[0017] The present invention will be described more fully below with reference to the accompanying drawings, in which exemplary embodiments of the present invention are illustrated. In the accompanying drawings, the same reference numerals represent the same or similar components or elements.

[0018] like Figure 1 and Figure 4 As shown, a convenient and beautiful lock device is used to lock a door cover 1 and a cover body 2 covered by the door cover 1. It includes a rotating body 3 rotatably mounted on the door cover 1. The rotating body 3 is located outside the door cover 1. The cover body 2 is provided with a locking groove 4 inside the rotating body 3. The rotating body 3 is provided inside the rotating body 3 with a locking portion that slides into or out of the locking groove 4 when the rotating body 3 is rotated back and forth. A reciprocating rotation limiter for the rotating body 3 is provided between the door cover 1 and the cover body 2. The reciprocating rotation limiter can improve the accuracy of locking and opening the lock.

[0019] like Figure 1-4 As shown, the door cover 1 is provided with a circular hole 5, and a connecting post 6 is provided protruding from the inner side of the rotating body 3. The connecting post 6 passes through the circular hole 5 and rotates with the circular hole 5. The end of the connecting post 6 is detachably connected to a cover 7. The connecting post 6 and the cover 7 can be detachably connected using a connecting bolt 8. Alternatively, an elastic hook can be provided at the end of the connecting post 6, and a hole groove is provided on the cover 7. The elastic hook passes through the hole groove and is hung on the cover at the hole groove by the elastic hook. The connecting post 6 is cylindrical, and a positioning groove 9 is provided on the cylindrical wall of the end of the connecting post 6. The cover 7 is recessed toward the rotating body 3 and is provided with a positioning ring groove 10 for accommodating the end of the connecting post 6. The positioning ring groove 10 is provided with a positioning protrusion 11 that is inserted into the positioning groove 9. In this way, the rotating body 3 and the cover 7 can rotate synchronously, preventing the rotating body 3 and the cover 7 from being disengaged after long-term use.

[0020] like Figure 3 and Figure 4 As shown, the reciprocating rotation limit device is a limit protrusion 12 protruding from both sides of the circular hole 5 on the door cover 1, and a limit ring groove 13 is provided on the inner side of the rotating body 3 at the outer periphery of the connecting column 6 for allowing the limit protrusion 12 to extend into. A limit block 14 is provided in the limit ring groove 13, and the rotation trajectory of the limit block 14 is located between the two limit protrusions 12. In this way, when the rotating body 3 rotates to lock and unlock the lock, the limit block 14 cooperates with the two limit protrusions 12 to achieve the accuracy of locking and opening.

[0021] like Figure 1 、 Figure 3 and Figure 4As shown, the door cover 1 is provided with a protrusion 15 protruding downward at the lower side of the circular hole 5, and the upper end of the cover body 2 is provided with a groove 16 cooperating with the protrusion 15, which can improve the tightness of the fit between the door cover 1 and the cover body 2, reduce the volume of the rotating body 3, and improve the overall compactness and aesthetics; the two limiting protrusions 12 are arc-shaped and the bottom extends into the protrusion 15 to be connected together, so that the bottom is in a closed state, which can improve the shielding and protection of the connecting column 6 and the circular hole 5, and a distance is left between the top ends of the two limiting protrusions 12. After the rotating body 3 and the stop cover 7 are connected through the connecting column 6, the limiting block 14 is located in the interval between the top ends of the two limiting protrusions 12 and rotates back and forth, and realizes the accuracy of locking and opening by cooperating with the top ends of the two limiting protrusions 12; the locking groove 4 is located at the lower side of the groove 16. The locking portion is an arcuate protrusion 17 protruding from the inner side of the outer ring wall of the retaining ring groove 13. The locking groove 4 is a locking strip 18 protruding from the cover body 2. The locking groove 4 is located between the locking strip 18 and the cover body 2 and opens downward. In this way, the arcuate protrusion 17, the locking strip 18, and the locking groove 4 all fall into the retaining ring groove 13 and are obscured by the rotating body 3, thereby greatly improving the aesthetics. The outer ring wall of the retaining ring groove 13 may be provided with a notch 19 to facilitate observation and avoidance of the locking strip 18. Furthermore, a certain amount of damping is provided during the rotation between the connecting post 6 and the circular hole 5, which improves the rotation feel and enhances the stability of the lock when opening or closing.

[0022] like Figure 2-3 As shown, the door cover 1 and the cover body 2 of the present invention can be respectively taken as an example of the cage cover and cage body of a hamster cage. The rear side of the cage cover is hinged to the rear side of the cage body, and a circular hole 5 is provided on the front side of the cage cover. The connecting post 6 of the rotating body 3 rotates through the circular hole 5 and is detachably connected to the blocking cover 7 via a connecting bolt 8. The cage cover is provided with a protrusion 15 protruding downward from the lower side of the circular hole 5. The upper end of the cage body is provided with a groove 16 that cooperates with the protrusion 15. A locking strip 18 is provided on the cage body below the groove 16. The locking strip 18 forms a downwardly opening locking groove 4 between the cage body and the rotating body 3. The rotating body 3 covers the circular hole 5, the connecting post 6, the connecting bolt 8, the protrusion 15, the groove 16, the locking strip 18, the locking groove 4, and the limiting protrusion 12, thereby improving the aesthetic quality of the viewing experience. When in use, the cage cover is tightly covered on the cage body, and the rotating body 3 is rotated to make the arc-shaped convex strip 17 slide into the locking groove 4 until the limit block 14 contacts one limit protrusion 12 to realize locking of the cage cover and the cage body. The rotating body 3 is rotated to make the arc-shaped convex strip 17 slide out of the locking groove 4 until the limit block 14 contacts another limit protrusion 12 to realize opening of the cage cover and the cage body. The rotating body 3 also serves as the handle of the cage cover. Grab the rotating body 3 and lift it up to open the cage cover, which is convenient and quick to operate.
