Detailed Implementation

[0027] like Figures 1-11 As shown, a push-button door lock includes an outer handle 100 and an inner handle 200 installed inside and outside the door. Both the outer handle 100 and the inner handle 200 are provided with a button 400 for engaging with a lock body 300 on the door. The button 400 is rotatably connected to the outer handle 100 and the inner handle 200. The lock body 300 includes a housing 310, and a guide block 320 is provided inside the housing 310 for unlocking and locking the lock body 300 through reciprocating motion within the housing 310. The rotation of button 400 on the outer handle 100 and the inner handle 200 forces the guide block 320 to reciprocate, thus unlocking and locking. By setting button 400 as a rotating structure, the guide block 320 inside the lock body 300 reciprocates through rotation, thus unlocking and locking. If button 400 is located on the outer end face of the handle, pressing button 400 while rotating it creates an unlocking and pushing action because it is pressed towards the handle. Entering the door only requires one step, which is very convenient.

[0028] The button 400 is provided with a pressing part 410 for easy pressing and rotation by human hand. The back of the pressing part 410 is provided with a protruding post 420 for unlocking and locking in conjunction with the guide block 320. The lock body 300 unlocks and locks by rotating the button 400 through the protruding post 420. The protruding post 420 is mainly used to extend the force point of pressing the guide block 320, which is highly practical.

[0029] The protruding post 420 is provided with a socket 421 for installing the guide post 430. The guide post 430 is fixedly assembled with the protruding post 420 by snapping into the socket 421 and in a tight fit. The lock body 300 unlocks and locks by rotating the button 400 with the guide post 430. The guide post 430 itself can be an integral structure with the protruding post 420. Considering the different thicknesses of the door panel, a guide post 430 of appropriate length can be inserted into the socket 421 during installation. This means that making the protruding post 420 and the guide post 430 separate is mainly to adapt to door panels of different thicknesses, which is highly practical.

[0030] The connecting part 440 is located on one side of the protrusion 420 and near the edge of the button 400. The button 400 of this application can be unlocked by pressing the one-way pressing guide block 320. The button 400 does not need to be set to rotate in both directions. Therefore, the design of setting the connecting part 440 at the edge is mainly to make the button 400 focus on rotation to unlock, increase the area of ​​hand pressing, and is more in line with ergonomics.

[0031] Both the outer handle 100 and the inner handle 200 are provided with mounting holes 110 for accommodating the button 400 and allowing the button 400 to rotate. The button 400 is rotatably connected to the outer handle 100 and the inner handle 200 through the mounting holes 110. The button 400 is provided with a connecting part 440 for mounting the pin 441. The mounting hole 110 is provided with a limiting hole 111 for engaging the pin 441. The button 400 achieves rotational engagement within the mounting hole 110 through the engagement of the pin 441 and the limiting hole 111. The end face of the button 400 is flush with the opening of the mounting hole 110, which is aesthetically pleasing. The axial direction of the pin 441 can be parallel to the horizontal line as shown in the attached figure, which conforms to ergonomic principles.

[0032] The button 400 is provided with a protrusion 450 to prevent the pressing part 410 from disengaging from the mounting hole 110. Both the outer handle 100 and the inner handle 200 are provided with a stop part 120 for engaging with the protrusion 450 at a position relative to the mounting hole 110. The button 400 achieves rotation limit through the engagement of the protrusion 450 and the stop part 120. The button 400 has elastic restoring force through the engagement of the tension spring. Since the guide post 430 rests on the guide block 320, and the guide block 320 is reset by the tension spring, the engagement of the protrusion 450 and the stop part 120 is to prevent the button 400 from rotating out of the mounting hole 110, which is highly practical.

[0033] The guide block 320 is provided with a stop portion 321 that engages with the button 400. The housing 310 is provided with a guide groove 311 that engages with the stop portion 321 and allows the button 400 to be inserted. The housing 310 is provided with a locking tongue 330 that engages with the guide block 320. The guide block 320 is provided with a guide surface 322 that forces the locking tongue 330 to reciprocate within the housing 310. The locking tongue 330 is provided with an inclined surface 331 that engages with the guide surface 322. The locking tongue 330 is unlocked by engaging with the guide surface 322 and the inclined surface 331, and by engaging with the guide block 320. The locking tongue 330 and the guide block 320 are vertically distributed and are linked by engaging with the guide surface 322 and the inclined surface 331. The guide block 320 is also provided with a tension spring (not shown in the figure) to prevent the button 400 from unlocking. The button 400 thus has an elastic restoring force. The unlocking and locking of the lock body is a relatively mature technology on the market, and will not be described in detail here. The guide block 320 can be unlocked by moving up and down.

[0034] The outer handle 100 is provided with a mounting groove 130 for cooperating with the lock cylinder device 500. A decorative cover 140 is provided at the opening of the mounting groove 130 for sealing the mounting groove 130. The decorative cover 140 is fixed to the mounting groove 130 to achieve a limited position on the outer handle 100. The design of the split decorative cover 140 serves to conceal the lock cylinder device 500, and can also modify the wood grain and other design language to integrate into the home decoration style.

[0035] The mounting groove 130 is provided with a first magnet 131, and the decorative cover 140 is provided with a second magnet 141 or a magnetic material at a position relative to the first magnet 131. The decorative cover 140 and the outer handle 100 are attracted and fixed together by the magnetic force between the first magnet 131, the second magnet 141 or the magnetic material. The magnetic material includes materials such as iron, cobalt, and nickel. The decorative cover 140 can be equipped with a second magnet 141 or a magnetic material. The magnetic attraction effect makes it convenient to install and remove the decorative cover 140, and it is highly practical.

[0036] The mounting groove 130 is provided with a slot 132 for fixing the key. The key is fixed in the mounting groove 130 by inserting it into the slot 132 and in a tight fit. Since this application is for an interior door lock and there is no need for anti-theft, the slot 132 can facilitate the storage of the key in daily life and is highly practical.
