Detailed Description of the Preferred Embodiments
[0031] The following further describes the present application in detail with reference to the attached Figures 1-5 drawings.
[0032] Figure 1 is a schematic three-dimensional view of the present application Figure 1 , Figure 2 is a schematic three-dimensional view of the present application Figure 2 . Referring to Figure 1 and Figure 2 , an integrated handle lock is installed on a cabinet door and includes a mounting panel 1. An installation groove is provided on the cabinet door, and the mounting panel 1 is embedded in the installation groove and fixed by screws. A gripping groove 11 and a perforation 12 are provided on the mounting panel 1, and the gripping groove 11 and the perforation 12 are arranged at intervals. A lock body 2 is provided in the perforation 12. The gripping groove 11 is used for a person to grip so as to facilitate the person to pull the mounting panel 1, thereby realizing the opening and closing of the cabinet door. That is, the gripping groove 11 functions as a handle, while the lock body 2 functions to lock the cabinet door to ensure that the cabinet door cannot be opened after being locked. In this way, the integrated design of the handle and the lock body 2 is realized on one mounting panel 1, thereby simplifying the installation steps, reducing the maintenance cost, and effectively improving the use convenience and overall aesthetics.
[0033] Figure 3It is a reference diagram of the exploded state of the lock body. Refer to Figure 3 The lock body 2 includes a toggle handle 21, a connecting shaft 24, a fixing member 23 and a locking piece 22. The fixing member 23 includes a limiting portion 232 and a threaded portion 231. The threaded portion 231 is provided with an external thread and the threaded portion 231 passes through the perforation 12 from the outside to the inside and is arranged on the mounting panel 1. At the same time, the outer diameter of the threaded portion 231 is smaller than the inner diameter of the perforation 12 and the outer diameter of the limiting portion 232 is larger than the inner diameter of the perforation 12. In this way, the limiting portion 232 cannot pass through the perforation 12 and will abut against the outer wall of the mounting panel 1. Further, a nut 233 is adaptively screwed on the threaded portion 231. When the nut 233 abuts against the inner wall of the mounting panel 1, the fixing member 23 will be firmly fixed on the mounting panel 1. The fixing member 23 has a hollow structure, and the toggle handle 21 is in the shape of a hollow cover. In this way, the toggle handle 21 can be sleeved outside the limiting portion 232, and the connecting shaft 24 is connected to the inner wall of the toggle handle 21. During the process of the toggle handle 21 being sleeved towards the outside of the limiting portion 232, the connecting shaft 24 will be inserted into the fixing member 23, that is, the connecting shaft 24 will sequentially pass through the limiting portion 232 and the threaded portion 231.
[0034] The length of the connecting shaft 24 is equal to the length of the fixing member 23. In this way, when the inner wall of the toggle handle 21 is attached to the end of the limiting portion 232, the end of the connecting shaft 24 away from the toggle handle 21 will be flush with the end of the threaded portion 231. Further, an internal thread hole 241 is provided on the end face of the connecting shaft 24 flush with the threaded portion 231. After the connecting shaft 24 is inserted in place, first place the end of the locking piece 22 on the end faces of the connecting shaft 24 and the threaded portion 231, and then pass the screw 242 through the locking piece 22 and screw it into the internal thread hole 241. In this way, the tail of the screw 242 will be screwed into the internal thread hole 241, and the head of the screw 242 will abut against and lock the locking piece 22. After the screw 242 locks the locking piece 22, a tightly attached state will also be formed between the locking piece 22 and the threaded portion 231. In this way, the toggle handle 21 can only rotate along its own axis and cannot move radially, thus realizing the fixation of the toggle handle 21.
[0035] Figure 4 It is a schematic three-dimensional view of the fixing member. Refer to Figure 4 And in combination with Figure 3, the limiting part 232 is in a circular tubular shape. There are two limiting holes 2321 on the outer wall of the limiting part 232, and the two limiting holes 2321 are spaced apart. In this way, a limiting rod 2322 is formed between the two limiting holes 2321. There is a hollow limiting protrusion 211 on the outer wall of the toggle handle 21. The limiting protrusion 211 and the toggle handle 21 are in a state of mutual communication. There are two connecting holes 212 at the connection between the limiting protrusion 211 and the toggle handle 21, that is, one end of the connecting hole 212 is located on the limiting protrusion 211, and the other end of the connecting hole 212 is located on the toggle handle 21, and the two connecting holes 212 are symmetrically arranged on both sides of the limiting protrusion 211. A pair of limiting strips 213 are provided at the inner end of the toggle handle 21, and a rotation area 214 is formed between the pair of limiting strips 213. A limiting block 2323 is provided at the end of the limiting part 232. When a person rotates the toggle handle 21, the limiting block 2323 will correspondingly rotate within the rotation area 214. When the limiting block 2323 rotates and contacts one of the limiting strips 213, the limiting block 2323 cannot continue to rotate. At this time, the limiting hole 2321 will be in a state of mutual communication with the connecting hole 212. At this time, the lock nose can be inserted into the limiting hole 2321 and the connecting hole 212 to achieve the locking effect on the toggle handle 21. At this time, the toggle handle 21 cannot rotate, and the locking piece 22 is also in a state of locking the cabinet door. When the cabinet door needs to be opened, pull out the lock nose and rotate the toggle handle 21 so that the limiting block 2323 can rotate to a state of contacting the other limiting strip 213. At this time, the limiting block 2323 is again in a state where it cannot continue to rotate, and the locking piece 22 also rotates to the unlocking state accordingly. That is to say, by controlling the rotation amount of the toggle handle 21 through the two limiting strips 213, the toggle handle 21 can be quickly and accurately switched between the locking and unlocking states, improving the convenience of operation.
[0036] Figure 5 is a reference diagram of the assembly state of the toggle handle and the connecting shaft. See Figure 5 and in combination with Figure 3, a plurality of convex ridges 243 are provided on the outer wall of the connecting shaft 24. The convex ridges 243 extend along the length direction of the connecting shaft 24. The plurality of convex ridges 243 are arranged at intervals along the circumferential direction of the connecting shaft 24 and are in contact with the inner wall of the threaded portion 231. A receiving groove 244 is provided between two adjacent convex ridges 243. The receiving groove 244 is opened on the outer wall of the connecting shaft 24. A spring 245 and a graphite sheet 246 are provided in the receiving groove 244. One end of the spring 245 is connected to the bottom of the receiving groove 244, and the other end of the spring 245 is connected to the bottom of the graphite sheet 246. The top of the graphite sheet 246 is attached to the inner wall of the threaded portion 231. The arrangement of the plurality of convex ridges 243 can realize the supporting effect on the connecting shaft 24, ensuring that the connecting shaft 24 can only rotate circumferentially in the threaded portion 231 and cannot move radially. At the same time, the contact between the convex ridges 243 and the inner wall of the threaded portion 231 can effectively reduce the friction during the rotation of the connecting shaft 24. Further, during the rotation of the connecting shaft 24, the spring 245 will push the graphite sheet 246 to keep it in a state of always being attached to the inner wall of the threaded portion 231. In this way, through the friction between the graphite sheet 246 and the threaded portion 231, a graphite lubricating layer can be formed on the inner wall of the threaded portion 231, thereby significantly improving the smoothness during the rotation of the connecting shaft 24, and also improving the feel of the operator rotating the handle 21.
[0037] The above are all preferred embodiments of the present application, and do not limit the protection scope of the present application accordingly. Therefore, all equivalent changes made according to the structure, shape, and principle of the present application should be covered within the protection scope of the present application.
