It should be noted that, without conflict, the embodiments of the present application and the features in the embodiments can be combined with each other. In the following description, many specific details are set forth in order to fully understand the present utility model. The described embodiments are only a part of the embodiments of the present utility model, rather than all of the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without making creative efforts fall within the scope of protection of the present utility model.

[0033] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by those of ordinary skill in the technical field to which the present utility model belongs. The terms used in the description of the present utility model herein are only for the purpose of describing specific embodiments, and are not intended to limit the present utility model.

[0034] Embodiment:

[0035] As Figure 1-10 shown, in this embodiment, a push - pull door anti - misoperation device with a structure of avoiding milling holes and height self - adaptation is provided, including a fixed base 1, a slider 2, a pushing rod member 3, and a telescopic member 4;

[0036] The slider 2 is in sliding fit with the fixed base 1, the lever member 3 is in hinged fit with the fixed base 1, a first elastic member 5 is provided at the hinge of the lever member 3 and the fixed base 1, the telescopic member 4 is in sliding fit with the lever member 3, and a second elastic member 6 is provided at the sliding fit of the telescopic member 4 and the lever member 3;

[0037] The specific structure of the lever member 3 in this embodiment is as follows:

[0038] A limiting portion 301 is provided at one end of the lever member 3, and a protruding extension portion 302 is provided at the other end. The limiting portion 301 can abut against the limiting boss 202. The extension portion 302 is provided with a first sliding groove 3021 for sliding fit with the telescopic member 4. The second elastic member 6 is provided in the first sliding groove 3021. A first link mounting hole 303 is provided in the middle of the lever member 3, and a link member 7 is provided in the first link mounting hole 303.

[0039] At the same time, a guiding and limiting groove 3022 is provided on the groove wall surface of the first sliding groove 3021. A limiting convex edge 401 is provided on the outer wall surface of the telescopic member 4 and is matched with the guiding and limiting groove 3022. A second mounting groove 402 for matching with the second elastic member 6 is provided on the telescopic member 4. The matching structure of the guiding and limiting groove 3022 and the limiting convex edge 401 can prevent the telescopic member 4 from being completely separated from the extension portion 302.

[0040] The specific structure of the fixed base 1 in this embodiment is as follows:

[0041] A second link mounting hole 101, a first mounting groove 102 for mounting the first elastic member 5, and an avoidance groove 103 for the extension portion 302 to pass through are provided on the fixed base 1. The second link mounting hole 101 is matched with the link member 7, and the lever member 3 is hinged to the fixed base 1 through the link member 7.

[0042] Finally, the specific structure of the slider 2 in this embodiment is as follows:

[0043] A second sliding groove 201 for sliding fit with the fixed base 1 is provided on the slider 2, and a limiting boss 202 is provided on the groove wall surface of the second sliding groove 201.

[0044] More specifically, the first elastic member 5 in this embodiment is a torsion spring member, and the second elastic member 6 is a spring member.

[0045] In this embodiment, the fixed base 1 is installed at the door leaf 8, and one end of the slider 2 is used to connect the lock point 10 or the transmission link.

[0046] When the door leaf 8 and the door frame 9 are in the separation stage, refer to Figure 3 and Figure 5, the anti-misoperation device is in a normally closed state. At this time, the limiting part 301 of the shifting rod 3 abuts against the limiting boss 202, and the first elastic member 5 is in a first compressed state. Because of the structure where the limiting part 301 abuts against the limiting boss 202, the relative movement of the slider 2 can be blocked, and thus the movement of the locking point 10 or the transmission connecting rod can be blocked.

[0047] When the door leaf 8 and the door frame 9 are in the closing stage, refer to Figure 4 and Figure 6 , the door frame 9 presses against the telescopic member 4. The spring pressure of the second elastic member 6 is greater than the elastic force of the first elastic member 5 on the shifting rod 3. The first elastic member 5 is in a second compressed state, and the shifting rod 3 will rotate clockwise until the limiting part 301 of the shifting rod 3 separates from the limiting boss 202 of the slider 2. At this time, the locking point 10 can push the slider 2 to move along the Figure 6 direction indicated by the arrow in the figure. After the locking point 10 moves upward, it can also move downward in the reverse direction, and drive the slider 2 of the anti-misoperation device to move downward together or the slider 2 moves downward by itself under the action of gravity during the downward movement.

[0048] Therefore, during the closing stage of the door leaf 8 and the door frame 9, various lap sizes of the door leaf 8 and the door frame 9 are often encountered. When the fitting space is relatively small, the door frame will further squeeze the anti-misoperation device. Since the two-stage compression stroke can be realized through the swinging structure of the shifting rod 3 and the telescopic structure of the telescopic member 4, while improving the profile adaptability, the operation of manually adjusting the height can also be eliminated, thus improving the efficiency.

[0049] One end of the slider 2 in this embodiment can directly abut against the locking point 10 or the connecting rod, or refer to Figure 10 , a connecting step portion 203 is provided at one end of the slider 2, and a connecting groove matching with the connecting step portion is provided on the locking point 10 and the connecting rod to realize the connection.

[0050] The above are only the preferred embodiments of the present invention, and do not impose any form of limitation on the present invention. Therefore, any modifications, equivalent changes and decorations made to the above embodiments based on the technical essence of the present invention without departing from the content of the technical solution of the present invention still fall within the scope of the technical solution of the present invention.
