It should be noted that in the description of the embodiments of this application, terms such as "first" and "second" are used only for the purpose of distinguishing descriptions and should not be construed as indicating or implying relative importance, nor should they be construed as indicating or implying order.

[0043] The terms "parallel" and "perpendicular" used in this application refer to "basically parallel" and "basically perpendicular" in practical operation. "Basically parallel" can be understood as parallelism with a certain degree of error, and similarly, "basically perpendicular" can be understood as perpendicularity with a certain degree of error.

[0044] like Figures 1-15 As shown, the latch provided in this embodiment includes a first housing 100, a second housing 200, and a lock cylinder 300. The first housing 100 is capable of engaging with the upper cover 401 of the box, and the second housing 200 is connected to the lower cover 402 of the box. The first housing 100 and the second housing 200 are rotatably coupled, so that the upper cover 401 and the lower cover 402 of the box are locked by rotating the first housing 100 to engage with the upper cover 401.

[0045] The lock core 300 is rotatably connected to the first shell 100, and the lock core 300 includes a locking state and an unlocking state; in the locking state, the lock core 300 is limitedly matched with the second shell 200 to relatively fix the first shell 100 and the second shell 200, and to limit the rotation between the first shell 100 and the second shell 200, so that the separation of the first shell 100 and the upper cover 401 of the box due to accidental touch is reduced, the stability of the locking of the upper cover 401 of the box and the lower cover 402 of the box is improved, and the locking effect of the box is improved; and in the unlocking state of the lock core 300, the lock core 300 can release the limitation with the second shell 200, so that the first shell 100 can rotate relative to the second shell 200 to realize the normal unlocking of the upper cover 401 of the box and the lower cover 402 of the box.

[0046] In actual situations, the first shell 100 and the lower cover 402 of the box can also be buckled, and the second shell 200 and the upper cover 401 of the box are connected to realize the locking of the upper cover 401 of the box and the lower cover 402 of the box, and the embodiments of the application do not limit this.

[0047] In order to facilitate the buckling of the first shell 100 and the upper cover 401 of the box, as shown in Figures 5-6 The first shell 100 is provided with a buckling part 105, and the upper cover 401 of the box is provided with a protrusion limitedly matched with the buckling part 105 to realize the buckling of the first shell 100 and the upper cover 401 of the box.

[0048] In some embodiments, the first shell 100 is of an elastic material, so that the buckling part 105 can be deformed during the buckling and matching with the upper cover 401 of the box to realize the buckling and limiting of the first shell 100 and the upper cover 401 of the box.

[0049] As shown in Figures 5-6 The lock core 300 includes a knob 301, a connecting piece 302, a limiting plate 303 and a locking piece 304. The knob 301, the connecting piece 302 and the limiting plate 303 are sequentially detachably fixedly connected through the locking piece 304, so that in the process of rotating the knob 301, the knob 301 can drive the limiting plate 303 to rotate at the second side of the first shell 100 through the connecting piece 302 from the first side of the first shell 100.

[0050] The first shell 100 is provided with a through hole 101 capable of accommodating the connecting piece 302, so that the connecting piece 302 can rotate inside the through hole 101 to realize the transmission of the acting force of the knob 301 from the first side of the first shell 100 to the limiting plate 303 on the second side of the first shell 100; and the second shell 200 is provided with a limiting groove 205 limiting matched with the limiting plate 303, and the relative rotation of the first shell 100 and the second shell 200 is limited by the limiting matching of the limiting plate 303 and the limiting groove 205, thereby improving the locking effect of the lock catch on the box body.

[0051] It should be noted that the first side and the second side of the first shell 100 are oppositely arranged, the first side of the first shell 100 is the side facing the outside, and the second side of the first shell 100 is the side facing the box body.

[0052] In some embodiments, the locking piece 304 is a threaded fastener, and the knob 301, the connecting piece 302 and the limiting plate 303 are all provided with threaded holes matched with the threaded fastener, so that the knob 301, the connecting piece 302 and the limiting plate 303 can be connected on the threaded fastener in sequence, thereby improving the stability of the lock cylinder 300 as a whole and ensuring the stability of the lock cylinder 300 during use.

[0053] In other embodiments, the locking piece 304 is a rubber column, and the knob 301, the connecting piece 302 and the limiting plate 303 are all provided with through holes matched with the rubber column, thereby improving the efficiency of connecting the knob 301, the connecting piece 302 and the limiting plate 303 on the rubber column in sequence and improving the assembly efficiency of the lock cylinder 300.

[0054] In order to facilitate the rotation of the knob 301, as shown in Figures 1-2 The first side of the knob 301 is provided with a handle to facilitate the rotation of the knob 301 by the handle, thereby improving the convenience of the operation process of the lock cylinder 300.

[0055] As shown in Figures 8-11 The second side of the knob 301 is provided with a first protrusion 3011, and the first side of the connecting piece 302 is provided with a recess 3021 matched with the first protrusion 3011, so that the connecting piece 302 and the knob 301 are quickly positioned by the first protrusion 3011 and the recess 3021, thereby facilitating the quick assembly of the lock cylinder 300.

[0056] In some embodiments, the second side of the connecting piece 302 is further provided with a second protrusion 3022, and the limiting plate 303 can be clamped inside the second protrusion 3022 to realize the quick positioning of the limiting plate 303 and the connecting piece 302, thereby further improving the assembly efficiency of the lock cylinder 300.

[0057] In this way, in the process of assembling the lock cylinder 300, through positioning of the first protrusion 3011 and the recess 3021 and positioning of the second protrusion 3022 and the limiting plate 303, the mounting hole of the knob 301, the mounting hole of the connecting piece 302 and the mounting hole of the limiting plate 303 are coaxially distributed, so as to facilitate the connection of the locking piece 304 in sequence, improve the assembly efficiency of the lock cylinder 300; at the same time, through the abutment of the first protrusion 3011 and the recess 3021 and the abutment of the second protrusion 3022 and the limiting plate 303, in the process of rotating the knob 301, the synchronous rotation of the knob 301, the connecting piece 302 and the limiting plate 303 can be further ensured, and the stability of the lock cylinder 300 in the unlocking and locking process is improved.

[0058] As shown in Figure 6 , the axis of the knob 301, the axis of the connecting piece 302, the axis of the limiting plate 303 and the axis of the locking piece 304 are consistent, so as to further ensure the synchronous rotation of the knob 301, the connecting piece 302 and the limiting plate 303.

[0059] In order to facilitate the rotation of the limiting plate 303, as shown in Figure 6 (only for distinction, not actually provided), the limiting plate 303 includes a fitting portion 3031 and an outwardly expanding portion 3032, the fitting portion 3031 is fitted with the second side of the connecting piece 302; the outwardly expanding portion 3032 is outwardly expanded from the first side of the limiting plate 303 to the second side of the limiting plate 303, and the outwardly expanding portion 3032 is farther away from the connecting piece 302 than the fitting portion 3031, and is limited and matched with the limiting groove 205 of the second shell 200 through the outwardly expanding portion 3032, so as to reduce the interference in the process of rotating the limiting plate 303, improve the smoothness in the process of rotating the lock cylinder 300, and improve the operation efficiency of the lock.

[0060] It should be noted that the first side of the knob 301, the first side of the connecting piece 302 and the first side of the limiting plate 303 are all the sides facing the outside, and the second side of the knob 301, the second side of the connecting piece 302 and the second side of the limiting plate 303 are all the sides facing the box.

[0061] As shown in Figures 14-15 , the connecting piece 302 is further provided with a guide block 3023, and the through hole 101 is provided with a guide groove 1011, so that the guide block 3023 can move along the guide groove 1011, and the guide groove 1011 can be limited and matched with the guide block 3023, so that the guide block 3023 can only move within the range of the guide groove 1011, reducing the over-rotation in the process of rotating the knob 301 to drive the limiting plate 303, and through the limitation of the movement of the guide block 3023 in the guide groove 1011, the switching of the limiting plate 303 between the unlocking and locking states can be more convenient, and the operation efficiency of the lock cylinder 300 is improved.

[0062] In some embodiments, the guide groove 1011 restricts the rotation range of the guide block 3023 to 90° so that the rotation angle of the limiting plate 303 is 90°. Of course, it can also be restricted to a rotation angle such as 60° or 120° that can realize the unlocking and locking of the lock cylinder 300. This application embodiment does not limit this.

[0063] To facilitate switching between unlocked and locked states of the lock cylinder 300, such as Figures 1-2 , Figures 14-15 As shown, a locking mark and an unlocking mark are provided on the first side of the first housing 100, and a directional mark is provided on the knob 301 of the lock cylinder 300. By rotating the knob 301, the directional mark is switched between the locking mark and the unlocking mark, which can drive the guide block 3023 to move in the guide groove 1011, so as to realize the limiting plate 303 and the second housing 200 to be limited and released. In this way, the status of the lock cylinder 300 can be clearly identified by the locking mark, the unlocking mark and the directional mark, and the working efficiency of the lock can be improved.

[0064] To facilitate rotation between the first housing 100 and the second housing 200, such as Figures 12-13 As shown, the first housing 100 includes a first connecting shaft 103; the first housing 100 has a connecting groove 102, and the second housing 200 is provided with a connecting protrusion 201 that is positioned and engaged with the connecting groove 102. The first housing 100 has a first connecting hole 104, and the connecting protrusion 201 has a second connecting hole 202. The first connecting shaft 103 can pass through the first connecting hole 104 and the second connecting hole 202, so that the connecting protrusion 201 can rotate relative to each other in the connecting groove 102, thereby realizing the rotational engagement between the first housing 100 and the second housing 200.

[0065] To achieve the connection between the second housing 200 and the box body, such as Figure 13 As shown, the second housing 200 includes a second connecting shaft 204, and the second housing 200 has a third connecting hole 203. The second connecting shaft 204 can pass through the third connecting hole 203 and the lower cover 402 of the housing, so that the second housing 200 can be detachably connected to the lower cover 402 of the housing.

[0066] The first connecting shaft 103 and the second connecting shaft 204 are arranged in parallel, so that a larger rotation angle can be provided during the relative rotation of the first housing 100 and the second housing 200.

[0067] In some embodiments, the first connecting shaft 103 and the second connecting shaft 204 are both damping rotating shafts, so that the first connecting shaft 103 and the first connecting hole 104 and the second connecting hole 202 are separated, the second connecting shaft 204 and the third connecting hole 203 and the lower cover 402 of the box body are separated, and the stability of the lock installation is improved while the first shell 100 and the second shell 200 are rotatably matched.

[0068] In practice, the lower cover 402 of the box body is provided with a mounting hole for the second connecting shaft 204 to pass through, so as to realize the connection between the second shell 200 and the lower cover 402 of the box body.

[0069] In the lock operation provided by the embodiments of the present application, first, the connecting piece 302 is placed in the through hole 101 of the first shell 100, then the knob 301 is positioned on the first side of the connecting piece 302, the limiting plate 303 is positioned on the second side of the connecting piece 302, and the lock cylinder 300 is assembled on the first shell 100 by sequentially connecting through the locking piece 304; then the connecting protrusion 201 is positioned and matched with the connecting groove 102, the first connecting shaft 103 passes through the first connecting hole 104 and the second connecting hole 202, and the assembly of the first shell 100 and the second shell 200 is realized; then the second connecting shaft 204 passes through the lower cover 402 of the box body and the third connecting hole 203, and the second shell 200 is installed on the lower cover 402 of the box body, so as to complete the assembly of the lock and the box body.

[0070] In the case of locking the box body, the first shell 100 is rotated to make the first shell 100 and the upper cover 401 of the box body engaged, then the knob 301 is rotated to the pointing mark on the knob 301 pointing to the locking mark, the limiting plate 303 and the second shell 200 are limited to match, the rotation between the first shell 100 and the second shell 200 is limited, and the locking effect of the box body is improved; in the case of unlocking the box body, the knob 301 is rotated to the pointing mark pointing to the unlocking mark, so that the limiting plate 303 is released from the limiting of the second shell 200, and the first shell 100 is rotated to release the engagement between the first shell 100 and the box body, so as to realize the unlocking of the box body.

[0071] As shown in Figure 16 The embodiments of the present application also provide a box body, which includes the lock described in the above embodiments.

[0072] Since the lock has the above technical effects, and the box body includes the lock, the box body also has corresponding technical effects, which will not be repeated here.

[0073] As shown in Figure 16 The lock includes various sizes to adapt to box bodies of different sizes, which can be adjusted and adapted according to actual conditions, and the embodiments of the present application do not limit this.

[0074] The above description of disclosed embodiments enables one of ordinary skill in the art to make and use the application. Various modifications to these embodiments will be readily apparent to those skilled in the art, and the generic principles defined herein can be applied to other embodiments without departing from the spirit or scope of the application. Thus, the present application is not intended to be limited to the embodiments shown herein but is to be accorded the widest scope consistent with the principles and novel features disclosed herein.
