However, the installation buckle structure of the existing cabinet door lock is integrally formed on the lock shell, and the lock is disassembled and assembled by forcing the elastic foot of the buckle to deform to avoid the side wall of the lock installation hole on the cabinet door panel. The cabinet door lock is inconvenient to disassemble, and the buckle structure is easily damaged during the disassembly process. In severe cases, the foot of the buckle structure will be broken, and after the buckle structure is damaged, the entire lock shell will be unusable. Summary of the invention

[0019] See attached Figures 1 to 4The utility model discloses a cabinet door lock installation structure, including a lock shell, the lock shell having a convex seat 1, the convex seat 1 is inserted into the lock installation hole 90 on the cabinet door plate 9, the side wall of the convex seat 1 is provided with a buckle 2 for fixing the lock shell buckle to the lock installation hole 90, the buckle 2 includes a base 21, the base 21 is provided with a clamping portion 22 for clamping with the periphery of the lock installation hole 90 when the convex seat 1 is inserted into the lock installation hole 90, the convex seat 1 of the lock shell is provided with an insertion fixing seat 11, the base 21 of the buckle 2 is provided with an insertion portion 23, the insertion portion 23 of the buckle 2 is detachably inserted into the insertion fixing seat 11, the insertion portion 23 of the buckle 2 is positioned and inserted into the insertion fixing seat 11 after the convex seat 1 is inserted into the lock installation hole 90, and the buckle 2 is limited to the clamping position (such as the clamping position) where the clamping portion 22 can clamp the periphery of the lock installation hole 90. Figure 4 After the protrusion 1 of the lock housing is inserted into the lock installation hole 90, the buckle 2 is inserted into the protrusion 1, and the buckle 2 is inserted into the limited position (that is, the buckle is inserted into the protrusion), and the clamping part of the buckle is clamped to the periphery of the lock installation hole to fix the lock on the door panel; compared with the traditional lock installation structure, another lock installation operation mode is provided, which makes the lock easy to disassemble and assemble, and the buckle 2 can be replaced independently.

[0020] The insertion portion 23 of the buckle 2 is inserted on the insertion fixing seat 11 along the insertion direction of the vertical protrusion 1 into the lock mounting hole 90 (the X-axis direction in the figure), so that the insertion direction of the buckle 2 is perpendicular to the insertion direction of the protrusion 1 into the lock mounting hole 90 (which is also the clamping direction of the clamping portion against the cabinet door panel), so that the buckle can clamp and fix the lock on the cabinet door panel more reliably, and the lock has better anti-pry performance.

[0021] In this specific embodiment, the buckle 2 is further provided with an elastic member that provides the clamping portion 22 to be elastically clamped on the periphery of the lock installation hole 90. The buckle is clamped on the cabinet door panel under the action of elastic force, ensuring that the buckle is reliably clamped on the cabinet door panel; and, because the buckle is inserted into the lock housing, under the limitation of processing accuracy, there is inevitably a matching gap between the insertion portion of the buckle and the insertion fixing seat, and under the existence of elastic force, the buckle can be elastically compressed, thereby eliminating the risk of shaking that may exist after the buckle is installed.

[0022] In order to further achieve a more stable installation of the buckle, the boss 1 is provided with a support boss 12 for supporting the elastic member, and the elastic member is supported on the support boss 12. The elastic member is supported on the support boss of the boss, and an elastic force is directly formed between the buckle and the boss, so that the buckle is installed on the boss more stably and reliably. On the other hand, the matching accuracy requirements between the plug-in part and the plug-in fixing seat are also reduced, the processing difficulty is reduced, and the setting of the elastic member is also relatively easy. As a feasible solution of the utility model, the elastic member can be an elastic connecting part on the clamping part for connecting to the base, that is, the elastic deformation of the clamping part itself is used to provide an elastic clamping force, but under this design, there is a problem that the clamping part is insufficient in strength and easy to break.

[0023] The buckle 2 is limited to a clamping position where the clamping portion 22 can clamp the periphery of the lock installation hole 90 through the concave-convex positioning match between the elastic member and the supporting boss 12. The elastic member and the supporting boss both have the function of positioning the buckle, and the elastic deformation of the elastic member can simultaneously provide displacement avoidance of the concave-convex positioning matching structure during the assembly process, making the buckle easier to disassemble and assemble. When the buckle is inserted and assembled, it has a certain gear sense.

[0024] As an embodiment of the present utility model, the elastic member is an arched spring sheet 24, both ends of which are fixed on the base 21, and the spring sheet 24 is supported on the supporting boss 12. The spring sheet can be integrally formed on the base of the buckle, or can be fixed on the base of the buckle; in this specific embodiment, integral forming is adopted to facilitate the processing and forming of the buckle. Of course, the structural form of the elastic member is not limited to the above specific embodiment, and can also be a spiral spring, a steel ball spring pin, etc.

[0025] Furthermore, a positioning groove 241 is recessed in the middle of the spring piece 24 , and the supporting boss 12 has a positioning support portion 121 that is inserted into the positioning groove 241 .

[0026] As a specific embodiment of the utility model, a seat body 111 of the plug-in fixing seat 11 is protruded on the end surface of the protruding seat 1, and a dovetail groove 112 is provided on the seat body 111 of the plug-in fixing seat 11, and the plug-in portion 23 of the buckle 2 is an plug-in block with a dovetail cross-sectional shape. At least two support convex ribs 13 arranged in the transverse direction are protruded on the seat body 111 of the plug-in fixing seat 11, which are supported by the wall of the lock installation hole 90, and the support convex ribs 13 have a sloped guide surface 131. The support convex rib is inserted into the lock installation hole under the guidance of the sloped guide surface, so that the lock and the lock installation hole wall are reliably supported, and the assembly is smoother.
