Embodiment Construction

[0055] The present invention will be further described below in conjunction with the accompanying drawings and specific embodiments.

[0056] refer to figure 2 and image 3 , shows schematic diagrams of two embodiments of socket brackets for car seats. Figure 4 and Figure 5 It is a schematic diagram of two embodiments of the installation state of the self-locking plug of the car seat. structure Figure 2 to Figure 5As shown, the seat back of the car seat 1 is generally provided with a socket frame 3 adapted to the self-locking plug 2, and the self-locking plug is installed by inserting and fixing the self-locking plug 2 into the socket frame 3 of the seat back 1 2. The position of socket frame 3 can be positioned at the top or the rear portion of the chair back. In this embodiment, the self-locking plug 2 is connected to the neck bracket for installing the neck bracket on the back of the car seat.

[0057] refer to Figure 6 to Figure 8 , shows a sectional view of t...

Abstract

The invention relates to a self-locking plug and an installation method thereof. The self-locking plug can be locked in a jack frame. The plug comprises a plug frame, a pair of clamping hooks, a sliding block, an elastic piece, and a locking mechanism. The clamping hooks that are hinged to the plug frame oppositely can rotate around the hinged parts, so that the clamping hooks partially protrude out of the side part of the plug frame to be clamped with the jack frame; the sliding block arranged on the plug frame in a sliding mode can slide to the position between the pair of clamping hooks along the plug frame and push the pair of clamping hooks to rotate around the hinged positions of the clamping hooks. The elastic piece arranged on the plug frame is connected with the sliding block, andthe elastic piece supports the sliding block to the position between the pair of clamping hooks and is abutted against the clamping hooks; the locking mechanism is rotatably arranged on the plug frame, the sliding block is limited to the side, away from the pair of clamping hooks, of the plug frame through the locking mechanism, and the elastic piece is compressed to generate an elastic force; the jack frame drives the locking mechanism to rotate to unlock the sliding block, the sliding block slides to the position between the pair of clamping hooks under the action of the elastic piece, thepair of clamping hooks are pushed to rotate around the hinged positions so that part of the clamping hooks can protrude out of the side portion of the plug frame to be clamped with the jack frame, andthe sliding block extrudes the pair of clamping hooks to be partially pressed on the jack frame.

Description

technical field [0001] The invention relates to the field of car seats, in particular to a self-locking plug and an installation method thereof. Background technique [0002] refer to figure 1 , shows a cross-sectional view of a prior art plug and socket frame connection. to combine figure 1 As shown, the plug frame 10a is inserted into the socket of the socket frame 50a to achieve fixed connection. Specifically, a block 20a is formed in the middle of the plug frame 10a, and a pair of hooks 30a are formed on opposite sides of the block 20a. The first end of the hook 30a is hinged to the plug frame 10a, and the second end of the hook 30a is formed with The protrusion, the middle part of the hook 30a and the stopper 20a are elastically connected by a spring 40a. The socket frame 50a is formed with a socket, and two opposite ends of the socket are formed with grooves for limiting protrusions. During installation, the plug frame 10a is inserted into the socket frame 50a thr...
