[0002] Plunge locks, also known as push-button locks, are increasingly becoming the preferred lock for cabinet doors and drawers due to their ease of use—they can be opened and closed without a key. However, the structure of most plunge locks on the market is not compact enough, and their transmission is relatively complex, resulting in less smooth operation and less stable use. Therefore, improvements are urgently needed. Utility Model Content

[0003] The purpose of this utility model is to overcome the shortcomings of the prior art and provide a pop-up cabinet door lock.

[0004] To achieve the above objectives, the present invention adopts the following technical solution:

[0005] A pop-up cabinet door lock includes a housing and a latch and a guide member disposed within the housing. A transmission rod is connected between the latch and the guide member and extends through the housing. A notch is provided on one side of the housing. The latch has a sliding groove and a protrusion corresponding to the notch. The transmission rod has a guide post and a sliding post inserted into the sliding groove. A spring is provided on the housing to abut against the transmission rod. The sliding post slides along the sliding groove and drives the protrusion to extend outward through the notch. An annular groove is provided inside the guide member. The guide post is inserted into the annular groove. A retaining groove is provided at the lower end of the annular groove to abut against the limiting guide post.

[0006] Preferably, the guide member is provided with an elastic abutment rod that abuts against the side wall of the housing, the guide post is abutted in the annular groove, the upper and lower ends of the annular groove are provided with abutment surfaces, the abutment surfaces are arranged in a counterclockwise direction towards the annular groove, and the two sides of the annular groove are provided with inclined surfaces.

[0007] Preferably, the groove is inclined upward and extends towards the notch side, and the sliding column is slidably disposed within the groove.

[0008] Preferably, the housing is provided with an inner cover, the transmission rod slides through the inner cover, the through section of the transmission rod is provided with a connecting end, and a button is connected to the connecting end.

[0009] Preferably, the housing is equipped with a locking plate, and the button is provided with a bracket opposite to the locking plate, and the bracket has an inner groove for the button to slide.

[0025] The present invention will be further described below with reference to the accompanying drawings and specific embodiments:

[0026] In the description of this specification, the terms "upper", "lower", "left", "right", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are used only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or unit referred to must have a specific orientation or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0027] like Figures 1 to 7 As shown, the pop-up cabinet door lock includes a housing 8 and a latch 6 and a guide 7 disposed within the housing 8. A transmission rod 5 is connected between the latch 6 and the guide 7 and passes through the housing 8. An inner cover 4 is disposed on the housing 8. The transmission rod 5 slides through the inner cover 4. The inner cover 4 confines the latch 6 and the guide 7 within the housing 8.

[0028] The transmission rod 5 has a connecting end 51 on its through section, and a button 1 is connected to the connecting end 51. The housing 8 is equipped with a locking plate 3, which is fixedly installed on the housing 8. The locking plate 3 abuts inward against the inner cover 4 inside the housing 8. The button 1 is provided with a bracket 2 that is opposite to the locking plate 3. The installation and fixing of this embodiment is achieved by abutting and fixing the bracket 2 and the locking plate 3 to the plate to be installed.

[0029] The bracket 2 has an inner groove 21 for the button 1 to slide. The button 1 slides up and down along the inner groove 21 to achieve the pressing action. The bracket 2 is provided with a washer 22. The button 1 is set through the washer 22, that is, one end of the button 1 passes through the washer 22 on the bracket 2 and is connected to the connecting end 51. The washer 22 is spaced between the bracket 2 and the button 1, thereby reducing the noise generated by the button 1 when it moves up and down during the pressing process.

[0030] The bracket 2 is provided with a connecting post 23, and the housing 8 is provided with a through hole 82 corresponding to the position of the connecting post 23. External bolts can pass through the through hole 82 and be connected to the connecting post 23 to install and fix the bracket 2, so that the bracket 2 will not loosen or fall off during use in this embodiment.

[0031] The button 1 is threaded onto the connecting end 51, thereby allowing adjustment of the distance between the bracket 2 and the locking plate 3 on the button 1 to accommodate the installation requirements of plates of different thicknesses.

[0032] The housing 8 has a notch 81 on one side, and the locking tongue 6 is provided with a sliding groove 62 and a protrusion 61 corresponding to the position of the notch 81. The outer contour of the protrusion 61 is smaller than the outer contour of the notch 81, and the protrusion 61 can extend out of the notch 81, thereby realizing the locking function of this embodiment.

[0033] The transmission rod 5 is provided with a guide post 53 and a sliding post 54 inserted into the sliding groove 62. The sliding post 54 is provided on both sides of the transmission rod 5. The sliding groove 62 and the sliding post 54 are provided in a one-to-one correspondence. The housing 8 is provided with a spring 9 that abuts against the transmission rod 5. Specifically, the bottom of the transmission rod 5 is provided with a groove 52. The spring 9 is provided in the groove 52. The lower end of the spring 9 abuts against the bottom plate of the housing 8 so that the transmission rod 5 always has an upward displacement tendency.

[0034] The sliding pin 54 slides along the sliding groove 62 and drives the protruding plate 61 to penetrate the notch 81 outward. Specifically, the sliding groove 62 is inclined upward and extends towards the notch 81. The sliding pin 54 is slidably disposed in the sliding groove 62. When the transmission rod 5 is displaced upward by the force of the spring 9, the sliding pin 54 moves upward synchronously. The upward sliding pin 54 moves along the sliding groove 62 and drives the lock tongue 6 to move inward, so that the protruding plate 61 can extend into the notch 81, thereby opening the lock.

[0035] Furthermore, the guide member 7 has an annular groove 71, and the guide post 53 is inserted into the annular groove 71. The lower end of the annular groove 71 is provided with a retaining groove 72 that abuts against and limits the guide post 53. When the sliding post 54 moves downward along the sliding groove 62 and the protruding plate 61 passes through the notch 81 outward, the guide post 53 is located in the retaining groove 72 at the lower end of the annular groove 71. The retaining groove 72 limits the guide post 53, thereby keeping the lock in the locked state of this embodiment.

[0036] Specifically, when the transmission rod 5 is pressed down by the button 1, the sliding column 54 moves down along the sliding groove 62 and drives the locking tongue 6 to move outward, so that the protruding plate 61 extends outward from the notch 81 to achieve the locking of the lock. At this time, the guide column 53 is engaged and limited in the slot 72, so that the lock can maintain the locked state.

[0037] When the transmission rod 5 is pressed again, the guide post 53 moves downward past the slot 72 and upward along the annular groove 71 (driven by the spring 9), and then the sliding post 53 moves upward synchronously to drive the bolt 6 to move inward, so that the convex plate 61 can extend into the notch 81, thereby opening the lock.

[0038] To improve the reliability of the operation in this embodiment, the guide member 7 is provided with an elastic abutment rod 75 that abuts against the side wall of the housing 8, and the guide post 53 is abutted against the annular groove 71, that is, the abutment rod 75 abuts against the side wall of the housing 8 so that the guide post 53 can always press against and fit against the annular groove 71.

[0039] Both the upper and lower ends of the annular groove 71 are provided with abutment surfaces 74, which are arranged in a counterclockwise direction toward the annular groove 71 (see reference). Figure 7 (As shown in the direction), when the guide post 53 is located at the lower end of the annular groove 71, the abutment surface 74 at the lower end of the annular groove 71 abuts against the left side of the guide post 53, so that the guide post 53 can only move upward along the right side of the annular groove 71. When the guide post 53 is located at the upper end of the annular groove 71, the abutment surface 74 at the upper end of the annular groove 71 abuts against the right side of the guide post 53, so that when the transmission rod 5 is pressed, the guide post 53 can only move downward along the left side of the annular groove 71.

[0040] The annular groove 71 has inclined surfaces 73 on both sides. The inclined surfaces 73 and the abutment surface 74 cooperate with each other to restrict and guide the displacement of the guide post 53, so as to ensure the reliability of the up and down displacement of the pressing transmission rod 5, that is, to realize the reliability of the lock opening and closing action. The cooperation structure of this embodiment is compact and the transmission structure is relatively simple. At the same time, the linkage switch action is more stable and smooth, and the practicality is better.

[0041] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
