Claims3
A lifting device for a playard, where the playard is mainly composed of a frame body and enclosures, the enclosures provide a safe space for a child to play and which can prevent the child from climbing out and falling, the lifting device comprising:
- a slide rail and a connector, wherein a slide groove is provided on a left side of the slide rail;
- a slide portion cooperating with the slide groove is provided on a right side of the connector;
- an elastic movable part is configured to move left and right relative to the connector and is provided inside the connector;
- the elastic movable part is in transmission connection with a pulling member;
- an upper part of the pulling member is hinged with the connector;
- a positioning post is fixed on a night end surface of the elastic movable part;
- a positioning hole for the positioning post to pass through is provided on the right side of the connector;
- a plurality of upper and lower limiting holes are provided on the left side of the slide rail;
- a front end surface of the pulling member is provided with a post hole extending backward;
- an elastic pressing post adapted to the post hole is provided inside the post hole;
- a front end of the elastic pressing post extends out of the post hole;
- a top surface of the front end of the elastic pressing post is provided with a baffle;
- a pressing portion is provided on the front end of the elastic pressing post;
- the pressing portion is located on a front side of the baffle, and an outer diameter of the pressing portion is greater than an outer diameter of the elastic pressing post;
- a bottom surface of a front end of the connector is provided with a downward extension plate;
- a bottom surface of the extension plate is adapted to the pressing portion to hold an upper part of the pressing portion;
- and the baffle is located on a rear side of the extension plate and is configured to abut against the extension plate;
- wherein the lifting device is configured such that when the connector needs to be lifted or lowered, the pressing post is first pressed backward, so that the pressing portion is separated from the extension plate, then, the pulling member is pressed such that the movable part is made to move to the left, so that the positioning post is separated from a currently cooperating limiting hole, so that the connector can be lifted or lowered in a tamper-proof manner.
