DETAILED DESCRIPTION

[0025] See attached Figures 1 to 8The utility model discloses a panel lock, comprising a panel 1 and a lock device 2, wherein the top of the panel 1 is provided with a handle groove 11, so that the panel 1 has a box-shaped body corresponding to the handle groove 11 and a skirt 13 on the edge of the box body. The panel 1 is usually designed with a sheet metal part, and an avoidance hole 12 is opened on the bottom wall of the handle groove 11. The lock device 2 comprises a handle assembly, a handle locking mechanism 21 and a lock hook assembly 24. The handle locking mechanism comprises a lock core assembly 211 and a lock catch portion 212 for locking / unlocking. The handle assembly comprises a handle 221 and a rotating shaft 222. The pull plate 2211 of the handle 221 is provided with oppositely arranged shaft connecting portions 2212 on both sides at one end. The lock core assembly 211 is installed on the other end of the pull plate 2211 of the handle 221. The shaft connecting portion 2212 of the handle 221 is connected to the rotating shaft 222 and can be rotated by operating the rotating shaft 222 through the handle 221. The assembly is installed on the rotating shaft 222, and the handle 221 drives the lock hook assembly through the rotating shaft 222. The lock device 2 is also equipped with a mounting base 23 with an assembly cavity 230. The mounting base 23 is detachably mounted in the handle groove 11. Shaft mounting holes 231 are provided on both sides of the mounting base 23. The pull plate 2211 of the handle 221 is placed above the mounting base 230. The shaft connecting part 2212 of the handle 221 corresponds to the position of the shaft mounting hole 231. Both ends of the rotating shaft 222 pass through the shaft mounting holes 231 and are connected to the shaft connecting part 2212. The lock hook assembly 24 is placed in the assembly cavity 230 of the mounting base 23. The assembly cavity 230 has an opening corresponding to the bottom of the mounting base 23. When the mounting base 23 is installed on the panel 1, the opening and the avoidance hole 12 correspond in position. The lock hook assembly can extend out of the handle groove 11 of the panel 1 along the opening and the avoidance hole, and the lock buckle part 212 is provided on the mounting base 23. In use, one option is to install the mounting base on the corresponding cabinet door without a panel, omitting the panel, providing customers with different options and reducing component costs. Another option is to install the mounting base in the panel's handle slot, achieving the same usage as a traditional panel lock. This panel lock adopts a modular design, reducing development and maintenance costs, and offers two lock variants of traditional panel locks, providing customers with more usage options.

[0026] To achieve the lock's waterproof seal; the mounting base 23 is a cover-shaped bottom opening, the opening end of the mounting base 23 is provided with a sealing gasket 232 surrounding the bottom opening of the assembly cavity (see Figure 3 ,exist Figure 5(Not shown in the figure), the rotating shaft 222 is provided with a sealing member that seals between the rotating shaft 222 and the shaft mounting hole 231. Thus, when the lock device is installed, the bottom of the mounting base is sealed against the door panel via the annular sealing ring, and the rotating shaft is sealed via the sealing member. Furthermore, this design offers the following advantages: when the lock device is assembled to the panel, the open end of the mounting base 23 is sealed against the bottom wall of the handle groove 11 via the sealing gasket 232. The independent mounting base covers the avoidance hole, sealing the avoidance hole. Furthermore, there is no need to open a hole in the panel for the rotating shaft installation, thus ensuring the integrity of the panel and improving the waterproof performance of the panel lock.

[0027] The mounting base's mounting structure utilizes a simple screw-locking mechanism. Specifically, the mounting base 23 is provided with a bolt connection 233, which is located within the annular space defined by the annular sealing ring 232. This ensures that the mounting area is also enclosed by the annular sealing ring, achieving a waterproof seal. Of course, under the guidance of this utility model and in combination with existing technology, those skilled in the art may also employ other detachable fixing structures, such as snap fasteners, other fasteners, and the like.

[0028] In order to achieve more convenient installation of the rotating shaft and ensure the waterproof sealing of the rotating shaft, the following design is adopted: the rotating shaft 222 includes an intermediate main shaft 2221 and a connecting end 2222 fixedly connected to the axial ends of the intermediate main shaft 2221, and fixed transverse pins 2223 are provided at both ends of the intermediate main shaft 2221. The fixed transverse pins 2223 are screws to achieve convenient and reliable fixation. The shaft connecting portion 2212 is provided with a shaft head insertion hole, and the head of the connecting end 2222 is in contact with the shaft connecting portion 2212. The shaft body of the connecting end 2222 is inserted into the end of the intermediate main shaft 2221 and is fixedly connected to the intermediate main shaft 2221 through the fixed transverse pin 2223. On the main shaft 2221, the connecting end 2222 is rotatably linked with the handle 221. The shaft head insertion hole is notched. The connecting end 2222 has a notched shaft portion 22221 that matches the shape of the shaft head insertion hole. The notched shaft portion 22221 is inserted into the notched shaft head insertion hole to achieve circumferential linkage. Of course, the shape for achieving circumferential linkage can also be in various forms, such as a spline shaft and hole, or a square hole and a square shaft; or fasteners can be used for fixation, etc. The sealing member is an O-ring 223 that is sleeved on the shaft body of the connecting end 2222. The O-ring 223 elastically presses axially against the outer end of the shaft mounting hole 231 to achieve sealing. The connecting end 2222 presses the O-ring 223 against the outer end of the shaft mounting hole 231 to achieve a reliable waterproof seal. At the same time, the O-ring can provide elasticity to facilitate the connection of the connecting end 2222 and the intermediate main shaft 2221. The assembly cavity 230 is provided with shaft auxiliary positioning parts 235 on the axial sides of the two shaft mounting holes 231. The shaft auxiliary positioning parts 235 have U-shaped positioning recesses, and the intermediate main shaft 2221 is supported in the U-shaped positioning recesses. In this way, when installing, the intermediate main shaft can be pre-positioned on the mounting base 23, making assembly more convenient. Figure 5 As shown, both axial ends of the intermediate main shaft 2221 are partially inserted into the corresponding shaft mounting holes 231. When installed in this way, after the lock hook assembly is assembled on the intermediate main shaft 2221, it can be pre-positioned on the inner mounting base, making assembly more convenient.

[0029] To achieve a more compact design, the following optimizations are employed: the outer end of the shaft mounting hole 231 has a stepped flared opening 234, an O-ring is positioned within the stepped flared opening 234, and the handle 221 has a side panel formed with a shaft connecting portion 2212. The shaft connecting portion 2212 is concave outward and convex inward along the axis of the rotating shaft 222 on the side panel, and the head of the connecting end 2222 is positioned within a recess 2212a on the outer side of the shaft connecting portion 2212. This achieves a compact fit, for example, ensuring a stable and reliable fit between the shaft connecting portion on the side panel and the inner base, and maintaining a large gap between the main portion of the side panel and the inner base to prevent scratches.

[0030] In order to further improve the sealing performance between the panel and the door panel, an annular sealing gasket 14 is provided on the skirt 13 of the panel 1. Moreover, in a further optimized design, a groove 141 is provided on the top surface of the sealing gasket 14, and the skirt 13 of the panel 1 is embedded in the groove 141.

[0031] One implementation method of the present utility model is as follows Figure 1 、 Figure 3 and Figures 5-7 As shown; the lock hook assembly includes a driven lock hook 241, a driving lock tongue 242 and a lock hook torsion spring 243, one elastic arm of the lock hook torsion spring 243 is hung on the driven lock hook 241, and the other elastic arm of the lock hook torsion spring 243 is abutted on the mounting base 23. The driven lock hook 241 is configured to be sleeved on the rotating shaft 222 in a manner that it can rotate relative to the rotating shaft 222. The hanging hole of the driven lock hook 241 is a circular hole, and the circular hole cooperates with the circumferential surface of the rotating shaft 222 to realize the positioning of the driven lock hook 241 on the rotating shaft 222 and the rotation relative to the rotating shaft. The driving lock tongue 242 is configured to be sleeved on the rotating shaft 222 in a manner of circumferential linkage with the rotating shaft 222, and an axial cross-section is provided on the rotating shaft 222. The sleeve hole of the driving lock tongue 242 adopts an adaptive shape to the shaft The cross-sections are matched to achieve rotational linkage. The driving lock tongue 242 has a toggle portion 2421. The spring force of the lock hook torsion spring 243 drives the driven lock hook 241 to rest against the toggle portion 2421. The driving lock tongue 242 is provided with a lock tongue torsion spring 244. The spring coil of the lock tongue torsion spring 244 is sleeved on the rotating shaft 222. One elastic arm of the lock tongue torsion spring 244 is hung on the driving lock tongue 242. The other elastic arm of the lock tongue torsion spring 244 rests on the mounting base 23. A lock tongue limiting wall 236 is provided on the mounting base 23. The driving lock tongue 242 is stopped and limited by the lock tongue limiting wall 236 relative to the other side of the side abutting the driven lock hook 241. The spring force of the lock tongue torsion spring 244 drives the driving lock tongue 242 to rest against the lock tongue limiting wall 236. Under this design, the driven lock hook 241 is driven by the driving lock tongue 242 on the rotating shaft 222, and the driving lock tongue 242 is provided with a lock tongue torsion spring 244. When the driven lock hook shakes or moves unexpectedly, the driving lock tongue is pressed against the lock tongue limiting wall under the force of the lock tongue torsion spring, and will not move with the driven lock hook, thereby avoiding abnormal noise from the handle and realizing a silent design of the lock.

[0032] The driving lock tongue 242 is a U-shaped member having two hanging arms 2422, and the toggle portion 2421 connects the two hanging arms. The U-shaped driving lock tongue is not only convenient for installation, but also achieves reliable cooperation with the driven lock hook and positioning cooperation with the mounting base.

[0033] In order to ensure reliable operation of the driving lock tongue and facilitate the installation and arrangement of the lock tongue torsion spring 244, the lock tongue torsion spring 244 is designed as a small torsion spring. A lock tongue torsion spring 244 is provided on each of the two hanging arms 2422 of the driving lock tongue 242. The driving lock tongue 242 is fitted on the hole on the rotating shaft 222 and has a side hole extending laterally. The end of the elastic arm of the lock tongue torsion spring 244 is bent to form a U-shaped hook head, and the U-shaped hook head passes through the side hole to be hung on the hanging arm 2422.
