Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without making creative efforts shall fall within the protection scope of the present invention.

[0027] In the description of the present invention, it should be understood that the terms "upper", "middle", "outer", "inner", etc. indicating orientations or positional relationships are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the components or elements referred to must have a specific orientation, be constructed and operated in a specific orientation, and thus cannot be construed as a limitation of the present invention.

[0028] Embodiment 1: In combination with Figures 1 to 5A push-pull door locking assembly is described, which includes: a door leaf 1 and a door frame 2. The door leaf 1 is slidably connected to the door frame 2, and a locking mechanism 3 for locking the door leaf 1 to the door frame 2 is installed on the door leaf 1. The locking mechanism 3 includes: a first housing 301 and a second housing 302. The first housing 301 and the second housing 302 are installed on the door leaf 1. A locking frame 303 is installed between the first housing 301 and the second housing 302. A first U-shaped pin 304 and a second U-shaped pin 305 are slidably connected to the locking frame 303. A compressed first thrust spring is installed between the first U-shaped pin 304 and the second U-shaped pin 305. A first rotating shaft 306 is rotatably connected to the first housing 301. A first extrusion ring 307 is installed on the first rotating shaft 306. A first extrusion block 308 for extruding the first U-shaped pin 304 is installed on the first extrusion ring 307. A first handle 309 is installed on the first rotating shaft 306. A first torsion spring is installed between the first rotating shaft 306 and the first housing 301. A second rotating shaft 310 is rotatably connected to the second housing 302. A second extrusion ring 311 is slidably connected to the second rotating shaft 310. A second thrust spring is sleeved between the second rotating shaft 310 and the second extrusion ring 311. A second extrusion block 312 for extruding the second U-shaped pin 305 is installed on the second extrusion ring 311. A tongue plate 313 is installed on the door frame 2. A baffle 314 is rotatably connected to the tongue plate 313. A second torsion spring is installed between the baffle 314 and the tongue plate 313.

[0029] Among them, the first torsion spring is used to rotate the first rotating shaft 306. After the person rotates the first rotating shaft 306 counterclockwise or clockwise through the first handle 309, the first torsion spring will reset the first rotating shaft 306. After the person enters the bathroom, they will pull the door leaf 1 to slide towards the door frame 2 through the first handle 309. While sliding, the first handle 309 will rotate counterclockwise. The first handle 309 will drive the first pressing ring 307 to rotate through the first rotating shaft 306. The rotating first pressing ring 307 will press the first U-shaped pin 304 through the first pressing block 308. A compressed first thrust spring is installed between the first U-shaped pin 304 and the second U-shaped pin 305. The first U-shaped pin 304 will press the second U-shaped pin 305 to move forward together through the first thrust spring. The second U-shaped pin 305 moving forward will make the second pressing ring 311 press the second thrust spring forward through the second pressing block 312. When the person makes the door leaf 1 contact the door frame 2 through the first handle 309, the person will let go. The first torsion spring will reset the first rotating shaft 306, and the first U-shaped pin 304 and the second U-shaped pin 305 will be reset by the second thrust spring. The first U-shaped pin 304 moves from the front end of the baffle 314 to the left side of the baffle 314, and the door leaf 1 is locked on the door frame 2 by using the baffle 314 and the first U-shaped pin 304. When opening the door from the inside of the bathroom, the person will rotate the first handle 309 clockwise. The first pressing block 308 will press the first U-shaped pin 304 again, so that the first U-shaped pin 304 and the second U-shaped pin 305 press the second thrust spring forward through the second pressing block 312. Then the first U-shaped pin 304 moves to the front end of the baffle 314, and the person can pull the first handle 309 to the right to separate the first U-shaped pin 304 from the baffle 314 and move the sliding door. A second torsion spring is installed between the baffle 314 and the tongue plate 313. When the person is outside, when the door leaf 1 slides, the first U-shaped pin 304 and the baffle 314 will be on the same horizontal line. The door leaf 1 can contact the door frame 2 without gaps, but the first U-shaped pin 304 will not hook the baffle 314 to lock the door leaf 1.

[0030] In this application, the first housing 301 and the second housing 302 are installed on the door leaf 1. A locking frame 303 is installed between the first housing 301 and the second housing 302. A first U-shaped pin 304 and a second U-shaped pin 305 are slidably connected to the locking frame 303. A compressed first thrust spring is installed between the first U-shaped pin 304 and the second U-shaped pin 305. A first rotating shaft 306 is rotatably connected to the first housing 301. A first extrusion ring 307 is installed on the first rotating shaft 306. A first extrusion block 308 for extruding the first U-shaped pin 304 is installed on the first extrusion ring 307. A first handle 309 is installed on the first rotating shaft 306. A first torsion spring is installed between the first rotating shaft 306 and the first housing 301. A second rotating shaft 310 is rotatably connected to the second housing 302. A second extrusion ring 311 is slidably connected to the second rotating shaft 310. A second thrust spring is sleeved between the second rotating shaft 310 and the second extrusion ring 311. A second extrusion block 312 for extruding the second U-shaped pin 305 is installed on the second extrusion ring 311. A tongue plate 313 is installed on the door frame 2. A baffle 314 is rotatably connected to the tongue plate 313. A second torsion spring is installed between the baffle 314 and the tongue plate 313, so that when a person touches the door leaf 1 and the door frame 2 through the first handle 309, the door will automatically lock, thus preventing people from forgetting to lock the door again, making the operation more convenient and saving time.

[0031] Embodiment 2: Based on Embodiment 1 and combined with Figure 3 it is described that a hook 315 is installed on the door frame 2, a second handle 316 is installed on the second rotating shaft 310, and a third torsion spring is installed between the second rotating shaft 310 and the second housing 302.

[0032] Among them, the second handle 316 can drive the second rotating shaft 310 to rotate. When the door leaf 1 is to be locked to the door frame 2 from the outside of the bathroom, the user rotates the handle counterclockwise, and the second pressing block 312 will no longer press the second U-shaped pin 305. The second U-shaped pin 305 moves forward under the action of the compressed first thrust spring, so that the second U-shaped pin 305 moves to the front end of the hook 315. After that, when the door leaf 1 contacts the door frame 2, the user releases the hand, and the third torsion spring will cause the second rotating shaft 310 to rotate and reset. The second pressing block 312 will press the second U-shaped pin 305 again, so that the second U-shaped pin 305 moves to the left side of the hook 315, and the second U-shaped pin 305 and the hook 315 are again on the same horizontal plane. When the door leaf 1 is to be opened, the user needs to rotate the second handle 316 clockwise on the outside, and the second U-shaped pin 305 will move to the front end of the hook 315 again. Then, the door leaf 1 is slid to the right through the second handle 316, and the door leaf 1 is separated from the door frame 2. The second U-shaped pin 305 and the hook 315 are used to lock or unlock on the outside of the bathroom. When the door leaf 1 is locked to the door frame 2 on the outside, the first U-shaped pin 304 will press the baffle 314 into the tongue plate 313. When the user rotates the first handle 309 inside the bathroom, the first U-shaped pin 304 and the second U-shaped pin 305 will move forward together. Even if the door leaf 1 is locked to the door frame 2 on the outside of the bathroom, the user inside the bathroom can also separate the door leaf 1 from the door frame 2 through the first handle 309.

[0033] In this application, a hook 315 is installed on the door frame 2, a second handle 316 is installed on the second rotating shaft 310, and a third torsion spring is installed between the second rotating shaft 310 and the second housing 302, enabling the user to lock the door leaf 1 to the door frame 2 on the outside of the bathroom, preventing the smell or moisture in the bathroom from escaping, and thus increasing the comfort of use.

[0034] Example 3: Based on Example 1 and combined with Figure 5 It is described that a limiting groove 317 is provided on the baffle 314, and a pin 318 for restricting the rotation of the baffle 314 is installed on the tongue plate 313. The pin 318 is slidably connected in the limiting groove 317.

[0035] In this application, a limiting groove 317 is provided on the baffle 314, a pin 318 for restricting the rotation of the baffle 314 is installed on the tongue plate 313, and the pin 318 is slidably connected in the limiting groove 317, so that the baffle 314 cannot rotate clockwise after being erected vertically. The locking strength between the baffle 314 and the first U-shaped pin 304 is increased through the pin 318, preventing the first U-shaped pin 304 from moving to the right after being on the same horizontal plane as the baffle 314, thereby improving the locking strength and increasing the safety factor.

[0036] Example 4: Based on Example 2 and combined with Figure 6It is described that a plurality of sliding grooves 319 are provided on the second rotating shaft 310, and a plurality of limiting blocks 320 for slidably connecting in the sliding grooves 319 are installed on the second pressing ring 311.

[0037] In this application, a plurality of sliding grooves 319 are provided on the second rotating shaft 310, and a plurality of limiting blocks 320 for slidably connecting in the sliding grooves 319 are installed on the second pressing ring 311, so that the second pressing ring 311 can rotate following the second rotating shaft 310 while sliding horizontally on the second rotating shaft 310, thereby increasing the connection strength between the second rotating shaft 310 and the second pressing ring 311 and extending the service life.

[0038] Example 5: Based on Example 4, it is combined with Figure 7 It is described that the second handle 316 is rotatably connected to the second rotating shaft 310, a lock core 321 is rotatably connected inside the second rotating shaft 310, a plurality of insertion blocks 322 for locking the second handle 316 and the second rotating shaft 310 are slidably connected inside the second handle 316, and a third thrust spring is installed between the insertion blocks 322 and the second handle 316.

[0039] Among them, the lock core 321 needs to be rotated using a key. After the door leaf 1 is locked on the door frame 2, a person uses the key to rotate the lock core 321 from the outside of the bathroom. The lock core 321 will no longer press on the plurality of insertion blocks 322, and the third thrust spring will push the insertion blocks 322 from the second handle 316 into the second rotating shaft 310. Without the restriction of the plurality of insertion blocks 322, the second rotating shaft 310 cannot be rotated through the second handle 316, and the person cannot separate the door leaf 1 from the door frame 2 outside the bathroom. However, the person can still separate the door leaf 1 from the door frame 2 through the first handle 309 inside the bathroom. To open the door leaf 1 from the outside of the bathroom, the lock core 321 can only be reset using the key, and then the door leaf 1 can be separated from the door frame 2 through the second handle 316.

[0040] In this application, the second handle 316 is rotatably connected to the second rotating shaft 310, a lock core 321 is rotatably connected inside the second rotating shaft 310, a plurality of insertion blocks 322 for locking the second handle 316 and the second rotating shaft 310 are slidably connected inside the second handle 316, and a third thrust spring is installed between the insertion blocks 322 and the second handle 316, so that a person can lock the door leaf 1 on the door frame 2 outside the bathroom to prevent the person from opening the door leaf 1 from the outside, and the person can still open the door leaf 1 from the inside of the bathroom, thereby increasing the locking security and preventing the person from being locked inside the bathroom.

[0041] Example 6: Based on Example 2, it is combined with Figure 6 It is described that fluff pads 323 are installed on both the second pressing ring 311 and the first pressing ring 307.

[0042] In this application, fluff pads 323 are installed on both the second extrusion ring 311 and the first extrusion ring 307. The fluff pads 323 can reduce the friction between the second extrusion ring 311 and the first extrusion ring 307 and the second U-shaped pin 305 and the first U-shaped pin 304, extend the service life, and can also use the fluff pads 323 to absorb the impact force when the second U-shaped pin 305 and the first U-shaped pin 304 fall from the second extrusion block 312 and the first extrusion block 308, thereby reducing the generation of noise and increasing the comfort of use.

[0043] Example 7: On the basis of Example 1, it is combined with Figure 2 for description. A plurality of rib plates 4 for increasing the connection strength are installed between the first housing 301 and the second housing 302.

[0044] In this application, a plurality of rib plates 4 for increasing the connection strength are installed between the first housing 301 and the second housing 302, which increases the connection strength between the first housing 301 and the second housing 302, and thereby extends the service life.

[0045] Example 8: On the basis of Example 1, it is combined with Figure 3 and Figure 5 for description. A rubber pad 5 for buffering is installed on the door frame 2.

[0046] In this application, a rubber pad 5 for buffering is installed on the door frame 2. When the door leaf 1 or the locking frame 303 contacts the door frame 2, the rubber pad 5 can buffer the impact force of the door leaf 1 or the locking frame 303, further extending the service life and reducing noise.

[0047] Example 9: On the basis of Example 2, it is combined with Figure 3 for description. A plurality of anti-slip grooves are provided on both the first handle 309 and the second handle 316.

[0048] In this application, a plurality of anti-slip grooves are provided on both the first handle 309 and the second handle 316, preventing people from slipping when moving the door leaf 1 using the first handle 309 or the second handle 316, and thus the operation is more convenient and labor-saving.

[0049] Example 10: On the basis of Example 2, it is combined with Figure 5 for description. The edge part of the baffle 314 is set as a first chamfer, and the edge part of the hook 315 is set as a second chamfer.

[0050] In this application, by setting the edge part of the baffle 314 as a first chamfer and the edge part of the hook 315 as a second chamfer, the first U-shaped pin 304 or the second U-shaped pin 305 slides along the first chamfer or the second chamfer to the left side of the baffle 314 or the hook 315, and thus the operation is more convenient and labor-saving.

[0051] Working process:
