[0032] The embodiments of the present utility model will be described in detail below with reference to the drawings.

[0033] As Figures 1 to 4 shown, the embodiments of the present utility model provide a self-weight locking structure, including:

[0034] A base 10, the base 10 includes an inclined surface 101 and a vertical surface 102, and a locking groove 1011 is formed on the inclined surface 101;

[0035] An installation plate 20, on which a first installation hole is provided;

[0036] A locking piece 30, the lower end of which is clamped in the locking groove 1011;

[0037] A rotating shaft 40, one end of which is connected to the upper end of the locking piece 30, and the other end passes through the first installation hole and is connected with a switch handle 50;

[0038] Wherein, the inclined surface 101 inclines towards the side away from the locking piece 30;

[0039] The locking piece 30 is locked and connected to the rotating shaft 40.

[0040] Specifically, both ends of the switch handle 50 are arc-shaped to prevent scratching the operator during unlocking, and the switch handle 50 is provided with anti-slip lines to prevent the unlocking failure caused by sliding during the unlocking process; the connection between the inclined surface 101 and the vertical surface 102 is arc-shaped, and the top angles of the inclined surface 101 and the vertical surface 102 are both arc-shaped, effectively preventing scratching the operator during the installation of the base 1, and also avoiding scratching the user during the use of the self-weight locking structure.

[0041] During use, rotate the switch handle 50 to make the rotating shaft 40 rotate, thereby driving the locking piece 30 to rotate away from the locking groove 1011 to achieve quick unlocking; when quickly closing the door, release the switch handle 50, and the locking piece 30 automatically falls into the locking groove 1011 due to its own weight to achieve locking, avoiding the situation of door closing failure caused by ineffective magnetic attraction, and the convenience is relatively high; the self-weight locking structure is simple, the operation is convenient, the manufacturing cost is low, and it can be widely used.

[0042] In order to prevent the switch handle 50 from rotating too large an angle, causing the locking piece 30 to fall to the side of the inclined surface 101 close to the locking piece 30, so that the locking piece 30 cannot be clamped into the locking groove 1011, resulting in door locking failure, a limiting hole 201 is further provided on the installation plate 20, and one end of the switch handle 50 is limited in the limiting hole 201, thereby controlling the rotation angle of the switch handle 50.

[0043] Specifically, in order to prevent part wear caused by friction between the switch handle 50 and the limiting hole 201 after repeated use, a wear-resistant layer is provided in the limiting hole 201, thereby improving the service life of the parts.

[0044] Further, a lock positioning sleeve 60 is provided at the position of the rotating shaft 40 between the lock piece 30 and the mounting plate 20. A locking nut 70 is provided at one end of the rotating shaft 40 passing through the lock piece 30. The lock piece 30 is limited and locked by the lock positioning sleeve 60 and the locking nut 70, preventing the lock piece 30 from being loosely connected to the rotating shaft 40, resulting in the inability of the rotating shaft 40 to drive the lock piece 30 to rotate out of the inside of the lock groove 1011 when the rotating shaft 40 rotates.

[0045] When the rotating switch handle 50 drives the rotating shaft 40 to rotate or the lock piece 30 drives the rotating shaft 40 to rotate due to its own weight falling, friction will occur between the rotating shaft 40 and the first mounting hole on the mounting plate 20. If the friction is too large, it will affect the opening or closing of the self-weight locking structure. Therefore, a lubricating layer is provided between the rotating shaft 40 and the first mounting hole to reduce the friction force and improve the smoothness of opening and closing the door.

[0046] Further, when closing the door, the lock piece 30 falls into the inside of the lock groove 1011 due to its own weight, and the lock piece 30 and the lock groove 1011 will collide. In order to prevent the lock piece 30 and the lock groove 1011 from being worn due to collision after repeated use, a buffer layer is provided inside the lock groove 1011 to reduce the impact force and improve the service life of the parts.

[0047] In order to prevent the top angle of the lock piece 30 from colliding and rubbing against the edge of the lock groove 1011 when the lock piece 30 falls into the lock groove 1011 due to its own weight, both sides of the bottom of the lock piece 30 are arc-shaped.

[0048] Further, a second mounting hole 1021 is provided on the vertical surface 102 for mounting the base 1. The user can install the base 1 at a position adapted to the lock piece 30 according to needs.

[0049] It should be noted that this self-weight locking structure is applicable to the use scenario of inward-opening doors without anti-theft requirements.

[0050] Finally, it should be noted that the above are only the preferred embodiments of the present invention and are not used to limit the present invention. Although the present invention has been described in detail with reference to the foregoing embodiments, for those skilled in the art, they can still modify the technical solutions recorded in the foregoing embodiments, or perform equivalent replacements for some of the technical features. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
