It will be easily understood by those skilled in the art that other advantages and benefits of the present application can be easily understood from the disclosure of the present application. Obviously, the described embodiments are part of the embodiments of the present application, but not all the embodiments. Based on the embodiments of the present application, all other embodiments obtained by those skilled in the art without creative labor are within the scope of the present application.

[0055] The terms such as "upper," "lower," "left," "right," and "middle" used in this specification are merely for clarity of description and are not intended to limit the scope of the invention. Any changes or adjustments to their relative relationships, without substantially altering the technical content, should also be considered within the scope of the invention.

[0056] like Figures 1-18 As shown, this embodiment provides a reversing structure for a push-pull lock, applied to a door handle, including a handle cover 1, a round bar 2, a handle base 3, a return spring 4, a cover plate 5, a square core 6, an annular piece 7, a connecting rod 8, a lever 9, and several screws or bolts.

[0057] The handle cover 1 is an L-shaped hollow structural component, comprising an inner wall panel 11, an outer wall panel 12, a top wall panel 13, and a bottom wall panel 14, all of which are L-shaped. The inner wall panel 11, the top wall panel 13, and the bottom wall panel 14 are integrally formed and detachably connected to the outer wall panel 12 to form an L-shaped space. The near end of the handle cover 1 (the end closest to the door or cover plate 5) has an opening, serving as the protrusion of the handle seat 3 within the L-shaped space; the near end has an outwardly convex arc surface to fit the cover plate 5 and allow it to swing or slide along the arc. Two sets of positioning grooves are provided at the corner inside the handle cover 1. The two sets of positioning grooves are arranged in parallel. The first set of positioning grooves 15 and the second set of positioning grooves 16 are spaced apart in the left-right direction. The two sets of positioning grooves are located at the corner of the inner side of the outer wall panel 12 (towards the inner wall panel 11). In this embodiment, the distance of the first set of positioning grooves 15 from the far end of the outer wall panel 12 is greater than the distance of the second set of positioning grooves 16 from the far end of the outer wall panel 12. Each set of positioning grooves has at least two positioning grooves, and the positioning grooves in the same set are arranged coaxially. In this embodiment, each set of positioning grooves has two positioning grooves, and the two positioning grooves in the same set are respectively located at the upper and lower ends of the outer wall panel 12. Two protrusions are provided inside the handle cover 1. The first protrusion 17 and the second protrusion 18 are spaced apart in height. In this embodiment, the first protrusion 17 is close to the top wall panel 13. Each protrusion has a removable protrusion 19 at its proximal end (the end closest to the door or cover plate 5). For example, the proximal end of the protrusion has a countersunk hole or a blind hole, and the side has a threaded hole communicating with the countersunk hole or blind hole. One end of the protrusion 19 is inserted into the countersunk hole or blind hole, and a set screw is tightened in the threaded hole on the side to fix the protrusion 19 to the proximal end of the protrusion. Generally, the protrusion is integrally formed on the inner side of the outer wall panel 12 (the side facing the inner wall panel 11).

[0058] The round stick 2 is used as a rotating shaft connecting the handle cover 1 and the handle base 3, and is arranged in the L-shaped space and is detachably fixed in the first set of positioning grooves 15 or the second set of positioning grooves 16 (two sets of positioning grooves are selected, and the selection is determined in the assembly process in production), for example, the end of the round stick 2 is fixed in the positioning grooves by screws. Alternatively, the round stick 2 is rotatably fixed in the first set of positioning grooves 15 or the second set of positioning grooves 16 (two sets of positioning grooves are selected), and in this case, the round stick 2 and the handle base 3 can be directly fixed without rotating connection.

[0059] The handle base 3 is arranged in the L-shaped space, and the distal end (the end away from the door or cover plate 5) is rotatably sleeved on the round stick 2. If the round stick 2 is rotatable, the connection relationship between the handle base 3 and the round stick 2 can not be a rotating connection. The proximal end (the end close to the door or cover plate 5) of the handle base 3 is provided with two through grooves 31, which penetrate the thickness of the handle base 3 in the left-right direction, and the two through grooves 31 correspond to the two protrusions one by one, and are used for moving the two protrusions in the through grooves 31. The proximal end of the handle base 3 is also provided with a pivot for rotatably mounting the push piece 9. Generally, the proximal end (the end close to the door or cover plate 5) of the pivot is detachably fixed with a pressing piece 32 by screws, and the displacement of the push piece 9 in the axial direction of the pivot is limited by the pressing piece 32. The proximal end of the handle base 3 is also provided with a mounting groove 33, and the mounting groove 33 is provided with a core barrel 34 for rotatably mounting the square core 6. The core barrel 34 is below or above the height direction of the two through grooves 31.

The reset spring 4 in the embodiment is a torsion spring, and the legs of the torsion spring act on the handle cover 1 and the handle base 3. The installation of the torsion spring is divided into two types, which correspond to the push state and the pull state respectively. The torsion spring is a commonly used reset part, and when installed, only the reset of the handle cover 1 needs to be ensured. The specific installation form can be conventionally installed according to the specific structure of the torsion spring.

[0061] The hollow cover plate 5 is provided with an inner concave arc surface matched with the outer convex arc surface, and the arc plate where the inner concave arc surface is located is provided with two sets of positioning holes 51 corresponding to the two sets of positioning grooves. The cover plate 5 is detachably connected with the handle base 3 by rotating and tightening the screws in a certain set of positioning holes 51. Generally, each set of positioning holes 51 is provided with a plurality of positioning holes 51, and in the embodiment, each set of positioning holes 51 is provided with six positioning holes 51. The handle base 3 is provided with six threaded holes at positions corresponding to the six positioning holes 51.

[0062] The square core 6 is rotatably mounted in the core barrel 34, and one end of the square core 6 is exposed from the core barrel 34.
