DETAILED DESCRIPTION

[0029] In order to make the purpose, technical solutions and advantages of the present invention more clearly understood, the present invention is further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only intended to explain the present invention and are not intended to limit the present invention. In addition, the technical features involved in the various embodiments of the present invention described below may be combined with each other as long as they do not conflict with each other.

[0030] The utility model provides a hidden door lock assembly for a bathroom, such as Figure 1-4 As shown, it includes a component 1 and a structure 2. By applying external force to make the component 1 and the structure 2 contact and separate, the door lock can be closed and opened. The component 1 includes a roller paddle 11, a spiral compression spring 14 and a slide bar 15 with a lock tongue 112 fixed at the lower end.

[0031] The component 2 includes a lock tongue seating groove 24; by toggling the roller paddle 11, external force is applied to or released from the spiral compression spring 14, driving the spiral compression spring 14 to compress and rebound, thereby pulling the slide bar 15 up and down to achieve the separation and engagement of the lock tongue 112 and the lock tongue seating groove 24, thereby controlling the door lock switch, which is easy to operate.

[0032] like Figure 5-8 As shown, a fixed-point roller 12 is fixed on the roller paddle 11 of the component 1, and the other end of the fixed-point roller 12 is connected to a truncated cone pressing sheet 13. A truncated cone pressing sheet stress layer 19 is provided under the truncated cone pressing sheet 13. A first spring fixing groove 110 and a clamping groove 113 are provided under the truncated cone pressing sheet stress layer 19. One end of the spiral compression spring 14 is fixed in the first spring fixing groove 110, and the other end of the spiral compression spring 14 is fixed in the second spring fixing groove 111 of the finishing female groove 16 clamped with the upper part of the structure 2.

[0033] The slot 113 is clamped with the slide bar 15, the lower end of the slide bar 15 is fixed with a lock tongue 112, and the middle position of the lower part of the lock tongue 112 is provided with a shear-resistant female groove 18;

[0034] The structure 2 includes a lock tongue return groove 21, a shear-resistant male groove 22, a finishing male groove 23, and a lock tongue landing groove 24, wherein the structure 2 is connected with the finishing female groove 16 of the component 1 through the finishing male groove 23. When connected, the shear-resistant male groove 22 is limited by the shear-resistant female groove 18, thereby achieving a tight engagement between the lock tongue 112 and the lock tongue landing groove 24, solving the problem of door leaf shaking caused by loose lock tongue of traditional door locks and enhancing the service life of the door lock.

[0035] In the embodiment of the present invention, as Figure 1-8As shown, the door lock closing process is as follows: by toggling the roller paddle 11, the fixed-point roller 12 and the connected truncated cone pressing piece 13 are driven to rotate. The long axis of the truncated cone pressing piece 1 rotates to be perpendicular to the truncated cone pressing piece stress layer 19 and presses it downward. After the truncated cone pressing piece 13 is pressed downward, it drives the first spring fixing groove 110 to move downward, and the second spring fixing groove 111 remains in place. The spiral compression spring 14 is compressed. At the same time, the slide bar 15 engaged with the first spring fixing groove 110 moves downward, and the lock tongue 112 is inserted into the lock tongue seating groove 24 of the structure 2. The door lock is locked. At the same time, the shear-resistant male groove 22 is limited by the shear-resistant female groove 18 to prevent the door lock from shaking.

[0036] The door lock is opened by shifting the roller paddle 11 in the opposite direction, which drives the fixed roller 12 and the connected truncated cone pressure plate 13 to rotate. The short side of the truncated cone pressure plate 13 rotates until it is parallel to the truncated cone pressure plate pressure layer 19, thereby separating from the truncated cone pressure plate pressure layer 19 and moving upward. The upward movement of the truncated cone pressure plate 13 drives the first spring fixing groove 110 upward, while the second spring fixing groove 111 remains in place. The helical compression spring 14 rebounds, pulling the slide rod 15 to drive the lock tongue 112 back to the lock tongue return groove 21, thereby achieving door lock opening.

[0037] Component 1 of the above-mentioned door lock assembly is installed and hidden in the door panel, with only the roller paddle 11 exposed. Component 2 is installed and hidden in the door frame and door panel. The door panel as a whole is simple and beautiful. When in use, external force is applied to paddle the exposed roller paddle 11, driving the round table pressing piece 13 to rotate, applying or releasing external force to the spiral compression spring 14, pulling the slide rod 15 to move, driving the lock tongue 112 at the bottom end of the slide rod to engage and separate with the lock tongue landing groove 24 to realize opening and closing of the door. The door lock is easy to operate.
