[0019] As Figures 1-5As shown in the figure, a new type of door lock for sliding doors includes a lock housing 1 and a lock base 2 that are fixedly installed on the door body. A hollow chamber 3 is formed between the lock housing 1 and the lock base 2. The chamber 3 has an opening on the lock housing 1. Inside the chamber 3, there is also a door handle 4 that enters and exits the chamber 3 through the opening, a mounting seat 5 fixedly assembled inside the chamber 3, and an elastic locking mechanism that elastically connects the door handle 4 and the mounting seat 5. The door handle 4 can be telescopically retracted into the lock housing 1 or the lock base 2, making the surface flush and having a better appearance effect. Through the elastic locking mechanism, the door handle 4 has three states. One is the state of short pressing to transition to locking and retracting, the second is that after locking is completed, the door handle 4 will not detach or pop out of the lock housing 1, and the third is that the door handle 4 is unlocked and smoothly pops out of the lock housing 1.

[0020] The elastic locking mechanism further includes a connecting rod 6, a hook rod, and a limiting rod 7 arranged in sequence. An elastic member is also provided between the connecting rod 6 and the limiting rod 7, and there is an elastic separation tendency between the connecting rod 6 and the limiting rod 7. The connecting rod 6 is used to connect the door handle 4. The hook rod adjusts the relative distance between the connecting rod 6 and the limiting rod 7, thereby realizing the hiding or protruding of the door handle 4. The limiting rod 7 is used to connect the mounting seat 5. The elastic member makes the connecting rod 6 and the limiting rod 7 have an elastic tendency to move away from each other, which is convenient for using the hook rod to pull the two closer to adjust the state, and is also beneficial to realizing the one-way cyclic movement in this embodiment.

[0021] One end of the hook rod is hingedly connected to the limiting rod 7. The hinge connection is achieved by setting holes and pins on the hook rod, so that the hook rod can still rotate within a certain range. For this reason, a wider groove is also provided on the limiting rod 7 to provide sufficient space, and no more elaboration and limitation will be made on this here. And the other end of the hook rod has a sliding portion that slidably cooperates with the connecting rod 6. A sliding groove 8 for limiting the sliding of the sliding portion is provided on the connecting rod 6. The sliding groove 8 is a continuous annular structure arrangement path, and the sliding portion slidably cooperates along the path of the sliding groove 8 in a one-way cycle. The sliding portion is generally a cylindrical protrusion, which is beneficial to smoothly slide and limit the cooperation in the sliding groove 8. It should be noted that the sliding groove 8 is not a regular circular ring structure, but a relatively closed annular path. To extend the telescopic distance of the door handle 4, an extension port and an extension groove 17 are specifically provided in this embodiment.

[0022] The slide 8 has a pressing section 9, a stop section 10 and an ejection section 11 which are sequentially inserted. The slide 8 is provided with a first clamping position 12 at the groove wall at the end of the pressing end. The slide 8 is provided with a concave second clamping position 13 at the groove wall of the stop section 10. The second clamping position 13 has a clamping point 14 corresponding to the first clamping position 12 and a clamping point 2 15 corresponding to the ejection section 11. The sliding part is blocked by the clamping point 14 to limit the reverse movement. The clamping point 2 15 is provided to be separated between the stop section 10 and the ejection section 11. The sliding part enters the pressing end and slides along the path. It stops at the first clamping position 12 and is acted upon by the elastic member. It automatically pulls back or rebounds in the opposite direction, thereby entering the stop section 10. In the stop section 10, it is restricted by the clamping point 14 and the clamping point 2 15, and it will neither return to the pressing section 9 in the opposite direction nor enter the ejection section 11. At this time, the door handle 4 is hidden in the lock housing 1 and remains in this state. When it needs to be released, an external force is pressed for a long time so that the sliding part enters the third position 16. After releasing the hand, the sliding part automatically slides out from the ejection section 11, and the door handle 4 extends out of the lock housing 1.

[0023] The stop section 10 is a hook-shaped structure, and the second stop point 15 is a hook-shaped structure arranged opposite to the stop section 10. Under this structural layout, it is fast to enter the stop section 10, but it is greatly limited to leave the stop section 10. The ejection section 11 is provided with a third stop position 16 connected to the stop section 10 at the beginning, and the first stop position 12 and the third stop position 16 are both arc-shaped limit grooves corresponding to the shape of the sliding part, and can play a sudden pause role, which is conducive to the rapid steering response of the sliding part, and enters the next designated position under the action of the spring. The slide 8 has an extending port and a connected extending groove 17 at the beginning of the pressing section 9 and the end of the ejection section 11. The extending port is close to the beginning of the pressing section 9, and the slide 8 has a guiding arc surface 18 on the groove wall at the extension port and the end of the ejection section 11. It can relatively extend the moving distance of the sliding part, that is, the telescopic distance of the door handle 4, and does not affect the basic design of the one-way circulation action, and the personnel operation is simple and reliable.

[0024] The door handle 4 is a U-shaped structure, and a ring groove 19 is provided near the end of one end of the connecting rod 6, and a clamping groove 20 is provided on the door handle 4 for the end of the connecting rod 6 to engage with. The connecting rod 6 is relatively hung on the door handle 4. In this embodiment, the installation direction is perpendicular to the movement direction of the door handle 4, which does not affect the stable use. The lock base 2 is also provided with a guide groove 21 on the chamber 3, and the door handle 4 is provided with a guide protrusion 22 that slides with the guide groove 21, so that the movement of the door handle 4 is more stable.

[0025] The connecting rod 6 and the limiting rod 7 are provided with flanges 23 for the elastic member to abut against. The elastic member is a spring. The side wall of the flange 23 is further provided with positioning blocks 24 which are in limiting cooperation with the mounting seat 5. The flanges 23 and the positioning blocks 24 play a role in stable guiding and reliable installation, and also facilitate the installation and use of the spring. The mounting seat 5 is provided with a positioning groove 25 for limiting sliding fit. The distance between the first clamping position 12 and the mounting seat 5 is shorter than the distance between the third clamping position 16 and the mounting seat 5. This feature enables the door handle 4 to be retracted and hidden by a short press, while a relatively long press is required to extend the door handle 4, thus avoiding accidental touching and opening of the door handle 4.
