[0025] In the description of this application, it should be noted that, unless otherwise expressly specified and limited, the terms "installation," "connection," and "linking" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection between two components. Those skilled in the art can understand the specific meaning of the above terms in this application based on the specific circumstances.

[0026] This application relates to a cabinet, which includes a cabinet door and a cabinet lock, with the cabinet lock located on the cabinet door.

[0027] The other components and operation of the cabinet are already described in the relevant technology for those skilled in the art, and will not be described in detail here. The structure of the cabinet lock and lock cylinder assembly 1000 will be introduced below.

[0028] This application relates to a cabinet lock, which includes a lock housing 2100, a lock handle 2200, and a lock cylinder assembly 1000. The lock housing 2100 is connected to the cabinet door. The lock handle 2200 is disposed on the surface of the lock housing 2100, and the lock cylinder assembly 1000 is disposed on the lock housing 2100. The lock handle 2200 is connected to the lock cylinder assembly 1000. The user can rotate the latch 1200 of the lock cylinder assembly 1000 through the lock handle 2200 to unlock or lock the cabinet lock. It is understood that the side of the lock housing 2100 where the lock handle 2200 is located is the outer side of the cabinet door.

[0029] This application relates to a lock cylinder assembly 1000, which includes a lock cylinder spindle and a bolt 1200. One end of the lock cylinder spindle is connected to a lock handle 2200, and the bolt 1200 is connected to the other end of the lock cylinder spindle. It is understood that when the user rotates the lock handle 2200, the lock handle 2200 drives the lock cylinder spindle to rotate, and the lock cylinder spindle drives the bolt 1200 to rotate.

[0030] The lock cylinder assembly 1000 includes a lock cylinder seat 1100, which is disposed in the lock housing 2100. The lock cylinder spindle passes through the lock cylinder seat 1100 and is rotatable in the lock cylinder seat 1100.

[0031] Considering that the bolt 1200 is prone to bending during lock picking, the cabinet lock design includes a reinforcing component in the lock cylinder assembly 1000. This reinforcing component is fixedly connected to the bolt 1200 to enhance its bending resistance and improve its anti-pry capability. Specifically, the reinforcing component is located on the surface of the bolt 1200 to increase its thickness, thereby strengthening its structural strength.

[0032] Specifically, the reinforcing assembly includes a reinforcing base 1301, which abuts against the surface of the latch bolt 1200 facing the lock cylinder seat 1100. Further, the reinforcing base 1301 is rotatably disposed on the lock cylinder seat 1100 so that it can rotate with the latch bolt 1200. Specifically, the reinforcing base 1301 is sleeved on the outer side of the lock cylinder seat 1100 and is mounted to the lock cylinder seat 1100 via rolling bearings.

[0033] Furthermore, the reinforcing assembly includes a reinforcing cover plate 1302, which is attached to another surface of the latch 1200 and connected to the main shaft of the lock cylinder. Referring to the accompanying drawings, the latch 1200 is positioned between the reinforcing cover plate 1302 and the reinforcing base 1301 to further increase the thickness of the latch 1200 and improve its bending resistance. One end of the reinforcing cover plate 1302 is fixedly connected to the main shaft of the lock cylinder so that the reinforcing cover plate 1302 rotates synchronously with the latch 1200.

[0034] Understandably, the reinforcing cover 1302 is fixedly connected to the reinforcing base 1301 to improve the connection strength among the reinforcing cover 1302, the bolt 1200, and the reinforcing base 1301. Specifically, the reinforcing cover 1302 and the reinforcing base 1301 are fixedly connected by multiple bolts or screws. The reinforcing cover 1302 and the reinforcing base 1301 can effectively transfer the force of bending the bolt 1200 to the front end of the bolt 1200, so that the bending point of the bolt 1200 is far away from the connection position between the bolt 1200 and the main shaft of the lock cylinder, thereby improving the anti-pry capability of the bolt 1200.

[0035] In related technologies, when a cabinet lock is pried open, the bending position of the latch 1200 is close to the mounting position between the latch 1200 and the main shaft of the lock cylinder. Therefore, the strength of the structure at the bending position of the latch 1200 at this time determines the anti-pry capability of the latch 1200. Since the bending position of the latch 1200 is far from the other end of the latch 1200, according to the lever principle, the latch 1200 is easily bent. Therefore, this application designs a reinforcing component to thicken the area of ​​the latch 1200 near the main shaft of the lock cylinder, so that the bending position of the latch 1200 is shifted to the other end of the latch 1200, shortening the distance from the bending position to the other end of the latch 1200, making the latch 1200 less prone to bending, thereby improving the anti-pry capability of the latch 1200.

[0036] In some examples, the reinforcing cover plate 1302 is bent to form a recessed fitting area that conforms to the shape of the latch 1200. The bend in the fitting area extends along the length of the latch 1200, which is located within the fitting area. In this case, the fit between the latch 1200 and the reinforcing cover plate 1302 is improved, as is the structural strength and bending resistance of the reinforcing cover plate 1302.

[0037] In some examples, the reinforcing cover 1302 is longer than the reinforcing base 1301 along the direction from the center of rotation of the latch 1200 to the other end. Referring to the attached diagram, when the cabinet lock encounters a pry lock, the latch 1200 is forced to bend towards the side where the reinforcing cover 1302 is located. Therefore, designing the reinforcing cover 1302 to be longer than the reinforcing base 1301 can further prevent the latch 1200 from bending. Furthermore, the reinforcing base 1301 is connected to the reinforcing cover 1302 with bolts or screws near the middle of the reinforcing cover 1302, which can transfer the force borne by the reinforcing cover 1302 to the reinforcing base 1301, further preventing the latch 1200 from bending.

[0038] Based on the above description of the lock cylinder assembly 1000, the following is a supplementary description of the cabinet lock.

[0039] In one embodiment, one end of the lock handle 2200 is hinged to the main shaft of the lock cylinder, and the hinge axis between the lock handle 2200 and the main shaft of the lock cylinder is perpendicular to the central axis of the main shaft of the lock cylinder. The lock handle 2200 can rotate relative to the main shaft of the lock cylinder so that the lock handle 2200 fits against the surface of the lock housing 2100 to prevent accidental operation or rotation of the main shaft of the lock cylinder by the lock handle 2200 without a key.

[0040] The other end of the lock handle 2200 can be tilted up so that the lock handle 2200 is tilted up on the surface of the lock housing 2100, so that the user can hold the lock handle 2200.

[0041] Furthermore, the surface of the lock housing 2100 is provided with a recessed handle receiving area 2101, which conforms to the shape of the lock handle 2200. The lock handle 2200 is at least partially located in the handle receiving area 2101, so that the lock handle 2200 fits against the surface of the lock housing 2100. When it is necessary to operate the lock handle 2200 to unlock, the user automatically or manually ejects the lock handle 2200 from the handle receiving area 2101, so that one end of the lock handle 2200 is raised.

[0042] In some examples, a torsion spring is fitted on the hinge shaft between the lock handle 2200 and the lock cylinder spindle, which can cause the end of the lock handle 2200 to be lifted under the action of the torsion spring. In other alternative examples, the lock housing 2100 uses an elastic structure with compressive elastic potential energy to spring up the lock handle 2200, and the elastic structure with compressive elastic potential energy is provided in the handle receiving area 2101.

[0043] It should be noted that the other end of the lock handle 2200 is detachably snapped into the lock housing 2100. The end of the lock handle 2200 used to snap into the lock housing 2100 can be raised for the user to grip and rotate to unlock. Specifically, the lock housing 2100 is detachably snapped into the lock handle 2200 by a limiting pin. When the limiting pin is separated from the lock handle 2200, the end of the lock handle 2200 is raised.

[0044] In one embodiment, at least one sidewall of the handle receiving area 2101 is provided with a toothed groove 2102, and the lock handle 2200 is provided with a toothed protrusion 2201 on the side facing the handle receiving area 2101.

[0045] When the lock handle 2200 is fitted into the handle receiving area 2101, the toothed protrusion 2201 is located in the toothed groove 2102. In this case, the engagement of the toothed groove 2102 and the toothed protrusion 2201 increases the number of mating points, thereby reducing the gap between the side wall of the handle receiving area 2101 and the side wall of the lock handle 2200, preventing the insertion of lock picking tools, and thus improving the anti-pry capability of the lock handle 2200 on the surface of the cabinet lock.

[0046] Regarding the arrangement of the toothed groove 2102, at least the following examples exist.

[0047] In some examples, at least two toothed grooves 2102 are provided on the two sidewalls along the length direction of the handle receiving area 2101, and the toothed grooves 2102 are arranged at intervals.

[0048] In other examples, the handle receiving area 2101 has at least two toothed grooves 2102 on its sidewall along the width direction.

[0049] In some other examples, the handle housing has at least two toothed grooves 2102 on both the sidewalls along the width direction and the two sidewalls along the length direction.

[0050] In one embodiment, the lock handle 2200 is provided with a side stop 2202, which increases the length and width of the lock handle 2200 so that the side stop 2202 covers the surface of the lock housing 2100.

[0051] When the lock handle 2200 is engaged with the handle receiving area 2101, the side stop 2202 fits against the surface of the lock housing 2100 to cover the toothed groove 2102 and the toothed protrusion 2201, as well as to cover the gap between the side wall of the lock handle 2200 and the side wall of the lock housing 2100.

[0052] Referring to the attached drawings, the toothed protrusion 2201 is provided on the side of the side stop 2202 facing the lock housing 2100.

[0053] In one implementation, the toothed protrusion 2201 is formed into a tapered structure along the direction of the protrusion, forming a wedge-shaped anti-pry structure. Correspondingly, the toothed groove 2102 is formed into a tapered inner cavity.

[0054] In this case, when the toothed protrusion 2201 engages with the toothed groove 2102, the sidewall of the toothed groove 2102 and the toothed protrusion 2201 make an angled fit, eliminating the gap between the sidewall of the toothed groove 2102 and the toothed protrusion 2201, which can improve the stability of the lock handle 2200 in the handle receiving area 2101 and further prevent prying.

[0055] Specifically, at least one sidewall of the toothed groove 2102 is arranged at an angle to form a tapered inner cavity.

[0056] In some examples, the cross-section of the toothed protrusion 2201 is trapezoidal, and correspondingly, the cross-section of the toothed groove 2102 is trapezoidal to improve the stability of the lock handle 2200 in the handle receiving area 2101. Referring to the accompanying drawings, the toothed groove 2102 is formed as a dovetail groove.
