[0003] Currently, most common household interior door locks use rotary handles. When the lock is not engaged, the handle needs to be turned to open the door, whether inside or outside. This method of opening the door does not quite conform to people's habits, as people are more accustomed to opening and closing doors by pushing or pulling handles. Especially in some special situations, such as when carrying heavy objects, using a rotary handle is very inconvenient. Summary of the Invention

[0004] In view of the above problems, the purpose of this invention is to provide a one-way rotating indoor sliding door lock to solve the problem of inconvenience of existing rotating door opening methods.

[0005] This invention provides a one-way rotating interior sliding door lock, comprising: sliding bases disposed on both sides of the door leaf, a lock body disposed inside the door leaf, and a square core penetrating the lock body and connected to the sliding bases on both sides.

[0006] The push-pull seat includes a handle, a panel, and a functional module fixed to the panel. The functional module includes: a handle return spring, a toggle piece, a one-way rotating block, a square-core toggle, a rotating piece engaging with the square-core toggle, and a square-core return toggle spring engaging with the rotating piece. One end of the one-way rotating block is hinged to a stud, the other end abuts against a small pin, and the middle part engages with a toggle fork at the lower end of the toggle piece.

[0007] The handle drives the actuating plate to rotate under the action of external force. The actuating plate actuates the one-way rotating block to rotate. The one-way rotating block rotates the rotating plate by actuating the small pins on the rotating plate. The rotating plate drives the square core actuating plate to rotate to complete the opening of the door.

[0008] After the door is opened, the handle automatically resets under the action of the handle reset spring, and the square core reset torsion spring rotates to drive the square core pusher to reset.

[0009] Furthermore, in a preferred embodiment, the functional module further includes: a noise-muffler block, wherein a return spring recess and a toggle plate fixing hole are provided within the noise-muffler block, wherein,

[0010] One end of the handle return spring is embedded in the return spring recess, and the actuating piece is inserted into the actuating piece fixing hole.

[0011] Furthermore, in a preferred embodiment, the functional module further includes: a bottom cover, studs, small pins, and positioning springs; wherein,

[0012] The stud is riveted to the bottom cover, and the small pin is riveted to the rotating plate;

[0013] The square core pusher passes through the bottom cover, the rotating plate engages with the square core pusher and the square core reset torsion spring, and the positioning spring is secured to the top of the square core pusher and the square core reset torsion spring on the bottom cover.

The fitting 41 is fitted into the fitting 21 of the cover 2, and the support plates 42 extend out from the cover hole 22. The support base 4 is fixed to the panel 3, and the functional module 5 is fixed to the panel 3 by the support base 4. The support plates 42 are fixed to the fittings; wherein, the sound-dampening block 501 and the actuating piece 502 are hinged to the upper end of the support plate 42 by a pin 511.

[0050] The specific structure of functional module 5 is further described in detail below. Functional module 5 includes: a muffler block 501, a toggle piece 502, a bottom cover 503, a stud 504, a square core toggle piece 505, a rotating piece 506, a small pin 507, a positioning spring 508, a one-way rotating block 512, a square core return torsion spring 513, and a pin 511. The muffler block 501 is provided with a toggle piece fixing hole 5011 and a return spring embedding hole 5012; the lower end of the toggle piece 502 is provided with a toggle fork 5021; the muffler block 501 is embedded in the muffler groove 43, and the support plate 42 and the muffler block 501 are both embedded in the fitting part 12 of the handle 1; the toggle piece 502 passes through the toggle piece fixing hole 5011, one end of the handle return spring 510 is embedded in the return spring embedding hole 5012, and the pin 511 hinges the muffler block 501 and the toggle piece 502 to the upper end of the support plate 42. A square core pusher 505 passes through the bottom cover 503. A rotating plate 506 engages with the square core pusher 505 and a square core return torsion spring 513. A positioning snap ring 508 is secured to the upper end of the square core pusher 505, fixing the square core pusher 505, rotating plate 506, and square core return torsion spring 513 onto the bottom cover 503. A stud 504 is riveted to the bottom cover 503, and a small pin 507 is riveted to the rotating plate 506. A through hole is provided at one end of the one-way rotating block 512, and one end of the one-way rotating block 512 is hinged to the stud 504 through the through hole. A support leg is provided at the other end of the one-way rotating block 512, and the other end of the one-way rotating block 512 abuts against the small pin 507 through the support leg. The middle part of the one-way rotating block 512 engages with the fork 5021 at the lower end of the toggle plate 502.

[0051] In an embodiment of the invention, when people open the door, they push or pull the handle 1. The handle 1 drives the actuating plate 502 to rotate, which in turn drives the one-way rotating block 512 to rotate. The one-way rotating block 512, by actuating the small pin 507 on the rotating plate 506, causes the rotating plate 506 to rotate, thereby driving the square core latch 505 to rotate. This, in turn, drives the latch bolt to move towards the inside of the lock body, causing the latch bolt to leave the lock hole, thus opening the door. After the door is opened, the external force disappears, the square core return torsion spring 513 rotates, driving the square core latch 505 to return to its original position. The noise-dampening block 501 provides cushioning at the hinge points of the main rotating components in this mechanism, reducing and lowering operating noise, and greatly improving the quietness effect.

[0052] This invention primarily utilizes the push-pull mechanism of the handle 1 to rotate the actuating piece 502 within it. The actuating piece 502 then rotates the one-way rotating block 512, which in turn rotates the rotating piece 506, thereby causing the square-core toggle 505 to rotate and achieve the door-opening function. After opening, the handle return spring 510 within the muffler block 1 automatically resets the handle 1, and the square-core return torsion spring 513 resets the square-core toggle 505. This invention features a simple structure, low manufacturing cost, and promising industrialization prospects.
