[0021] A setting pin is placed at the bottom of the outer handle.

[0022] Compared with the prior art, the present invention has the following beneficial effects: the present invention has a scientific and reasonable structure and is safe and convenient to use:

[0023] 1. By setting the first bracket, the clamping arc block, the stopper, the mounting circular hole, the second bracket, the fixing hole and the special-shaped hole, the clamping arc block inside the first bracket is clamped with the scroll spring to limit the spring, which is convenient for the spring to realize the reset function and drive the handle to automatically reset after rotation. The stopper can block the pushing protrusion of the rotating ring to avoid reverse rotation, and the setting of the special-shaped hole can provide rotation space for the special-shaped block, so that the special-shaped block can rotate stably, thereby making the overall connection more compact and stable.

[0024] 2. By arranging a slider, a lock tongue, a lock core shaft, a push rod, a shift block, a card block, a rotating ring, an operating ring, a special-shaped block, a pushing protrusion and a scroll spring, the push rod is pushed by the shift block to drive the card block to engage with the special-shaped block. When the lock core shaft rotates, the push rod, the card block, the operating ring, the special-shaped block and the pushing protrusion can be driven to rotate at the same time. The pushing protrusion drives the slider to move and drives the lock tongue to separate from the lock core seat to achieve unlocking. The push rod is pushed to separate the card block from the special-shaped block. Rotating the lock core shaft again will not drive the operating ring to rotate, thereby failing to move the slider and the lock tongue, thereby achieving locking of the door lock.

[0025] 3. By setting an outer base, an outer handle, an inner base, an inner handle and a toggle hole, the outer handle and the inner handle are directly connected to the lock core shaft, which makes the operation more convenient and direct. In addition, a base embedded in the door panel is set for connection, so that the main body of the door lock can be fully embedded in the door panel. The operation can be completed by simply exposing the handle, which saves volume and is more beautiful.

[0026] To summarize, the lock core and lock core bracket are embedded in the door panel, and the inner handle and outer handle connected to the lock core shaft are installed on the outside of the door panel. The inner handle is held and the thumb block moves to drive the card block to move, so the door lock can be locked and opened. Compared with the traditional rotation locking method, the operation is more convenient. The handle is connected to the lock core shaft and can be rotated in the locked state to avoid damage caused by sudden pressure when locking. The structure is simpler and compact. The simple and compact structure also enables the door lock to be embedded in the door panel for installation. The door lock installation is more stable, saving installation space, and the door lock and door panel are integrated to be more beautiful. BRIEF DESCRIPTION OF THE DRAWINGS

A limiting protrusion 308 is arranged on the outside of the rotating ring 307, and an operating ring 309 is rotatably sleeved on one end of the rotating ring 307. A special-shaped block 310 is connected to the top of the rotating ring 307. A slot 311 is provided at the bottom of the special-shaped block 310, and the holes in the middle of the lock core shaft 303 and the rotating ring 307 are both rectangular structures. The top of the block 306 is engaged with the slot 311 at the bottom of the special-shaped block 310, so that the lock core shaft 303 and the rotating ring 307 are stably engaged and can rotate together. A pushing protrusion 312 is connected to the outer side of the rotating ring 307, and the rotating ring 307 and the limiting protrusion 308 are an integrated structure, which makes the limiting protrusion 308 more secure. The pushing protrusion 312 is engaged with one end of the slider 301, so that the pushing protrusion 312 drives the slider 301 to move when rotating. A spiral spring 313 is connected to the other end of the rotating ring 307, and one end of the inner side of the spiral spring 313 is connected to the rotating ring 307, and one end of the outer side of the spiral spring 313 is engaged with the clamping arc block 102, which is convenient for fixing the spiral spring 313 and resetting the rotating ring 307.

[0049] The two ends of the lock core shaft 303 are connected with handles 2, the lock core bracket 1 is embedded in the door panel, the lock core seat 4 is embedded in the outer frame of the door, and the lock tongue 302 is magnetically attracted to the lock core seat 4.

[0050] The handle 2 includes an outer handle 202 and an inner handle 204;

[0051] An outer handle 202 is clamped on one end of the lock core shaft 303, and an inner handle 204 is clamped on the other end of the lock core shaft 303. An outer base 201 is installed at the connection between the outer handle 202 and the lock core shaft 303, and an inner base 203 is installed at the connection between the inner handle 204 and the lock core shaft 303. A toggle hole 205 is opened on the top of the inner handle 204, and the toggle block 305 is slidably clamped in the toggle hole 205 of the inner handle 204. The toggle hole 205 is a long strip structure, which is convenient for limiting the toggle block 305.

[0052] A strip-shaped placement hole is provided at the bottom of the outer handle 202, a bolt is connected to the bottom of the outer handle 202, a placement plate for blocking the placement hole is connected to the bottom of the bolt, the dial pin 5 is placed in the placement hole and blocked by the placement plate, and a plurality of dialing circular holes are provided at one end of the push rod 304 corresponding to the placement hole position;

[0053] A spring is installed at the bottom of the inner handle, a ball is clamped on the top of the spring, and a groove is opened at the position of the push rod 304 corresponding to the ball.

[0054] The working principle and use process of the present invention are as follows: when installing the door lock, grooves are made at the corresponding positions of the door panel, holes are punched at the corresponding positions of the rotating ring 307, and then the lock core 3 is installed between the first bracket 101 and the second bracket 105, and the lock core rotating shaft 303, the push rod 304, and the shift block 305 of the lock core 3 are pulled out, and then the first bracket 101 and the second bracket 105 are clamped together, and fixed in the fixing holes 106 in the middle of the first bracket 101 and the second bracket 105 with screws, and then the first bracket 101 and the second bracket 105 are clamped together in the door panel, and then screwed into the fixing holes 106 at the ends of the second bracket 105 to fix them with the door panel;

[0055] Insert the inner base 203 into the door panel from the outside so that the inner base 203 is connected to the special-shaped hole 107, insert the outer base 201 into the door panel from the outside so that the outer base 201 is connected to the mounting circular hole 104, and then insert the lock core shaft 303 and the push rod 304 into the middle of the rotating ring 307 from the middle of the inner base 203, so that the block 306 in the middle of the push rod 304 is connected to the inside of the slot 311 at the bottom of the special-shaped block 310, and one end of the lock core shaft 303 passes through the outer base 201;

[0056] Then, the inner handle 204 is clamped and fixed to the end of the lock core shaft 303, so that the shifting block 305 is placed inside the shifting hole 205 at the top of the inner handle 204, and one end of the inner handle 204 is in contact with the inner base 203, and the outer handle 202 is clamped and fixed to the end of the lock core shaft 303, so that one end of the outer handle 202 is in contact with the outer base 201;

[0057] Finally, the lock core seat 4 is embedded and installed in the door outer frame to complete the installation of the door lock;

[0058] After the door lock is installed, only the outer handle 202 and the inner handle 204 are placed outside the door panel, and the lock core 3 and the lock core bracket 1 are embedded in the door panel. The outer handle 202 and the inner handle 204 are directly connected through the lock core shaft 303. When unlocking, the clamping block 306 is clamped with the clamping groove 311 of the special-shaped block 310, and the outer handle 202 is rotated outside the door to drive the lock core shaft 303 to rotate, thereby driving the rotating ring 307, the push rod 304 and the clamping block 306 to rotate, the limiting protrusion 308 contacts the stopper 103, and the spiral spring 313 is wound tighter inside, and the clamping block 306 drives the operating ring 309, the special-shaped block 310 and the pushing protrusion 312 to rotate, and the special-shaped block 310 moves in the special-shaped hole 107, and the pushing protrusion 312 pushes the slider 301 and the lock tongue 302 to move, so that the lock tongue 302 moves out of the lock core seat 4 to achieve unlocking;

[0059] After the outer handle 202 is released, the rotating ring 307 is driven to rotate and reset through the reset movement of the spiral spring 313, so that the lock core shaft 303, the operating ring 309, the special-shaped block 310 and the pushing protrusion 312 are all rotated and reset, driving the slider 301 and the lock tongue 302 to move, so that the lock tongue 302 is stuck in the lock core seat 4;

[0060] When the door lock is locked, the shift block 305 is moved along the shift hole 205, so that the push rod 304 and the block 306 are moved, and the block 306 is moved out of the slot 311 of the special-shaped block 310. At this time, the outer handle 202 and the inner handle 204 are rotated, and the lock core shaft 303, the push rod 304, the block 306 and the rotating ring 307 are still rotated. However, since the block 306 is separated from the special-shaped block 310, it cannot drive the operating ring 309 and the slider 301 to move, thereby realizing the locking of the door lock;

[0061] After the door lock is locked inside, the bolt is unscrewed from the outer handle outside the door to remove the placement plate, and the pin 5 is taken out from the placement hole. The pin 5 is inserted into the dialing hole from the placement hole to move the push rod 304, so that the lock can be released, which is convenient for unlocking from outside the door in an emergency;

[0062] When the push rod 304 is being pushed, the ball is squeezed into the groove at the bottom of the push rod 304 by the spring. The user hears a click sound of the ball, indicating that the groove is pushed into position, making it convenient for the push rod 304 to be pushed into place.

[0063] The outer handle 202 and the inner handle 204 are directly connected by a lock core shaft 303, and a push rod 304 that can be pushed is set inside the lock core shaft 303 to control the movement of the block 306 on the push rod 304, so that when the block 306 is engaged with the special-shaped block 310, the slider 301 and the lock tongue 302 are driven to move. When the block 306 is separated from the special-shaped block 310, the slider 301 and the lock tongue 302 do not move with the rotation of the lock core shaft 303. The structure is simple and compact, occupies a small volume and is easy to fix. Only the outer handle 202 and the inner handle 204 need to be exposed outside the door panel, which is more beautiful.

[0064] Finally, it should be noted that the above description is only a preferred example of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or replace some of the technical features therein by equivalents. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
