Detailed Description

The present invention will be described in detail with reference to the following embodiments, wherein like or similar elements are designated by like reference numerals throughout the drawings or description, and wherein the shape, thickness or height of the various elements may be expanded or reduced in practical applications. The embodiments of the present invention are provided only for illustration, and not for limiting the scope of the present invention. Any obvious and obvious modifications or alterations to the present invention can be made without departing from the spirit and scope of the present invention.

Example 1

Please refer to fig. 1-5, in the embodiment of the present invention, a safety lock comprises a lock sleeve 1, a fixing cover 2 and a rotation shaft 3, the rotation shaft 3 is inserted into a through hole formed in the fixing cover 2, the rotation shaft 3 can only be taken out from the lower side of the fixing cover 2, and cannot be taken out from the upper side of the fixing cover 2, the fixing cover 2 plays a role in limiting the position of the rotation shaft 3, the whole body formed by the rotation shaft 3 and the fixing cover 2 is inserted into the first cavity 11 of the lock sleeve 1 through the first fixture block 21, and the rotation shaft 3 is pressed to rotate in the fixing cover 2 and the lock sleeve 1 to realize the unlocking and locking functions, so that the safety lock has the advantages of simple operation, high safety performance and low cost.

Furthermore, a first chamber 11 is arranged on the lock sleeve 1, the first chamber 11 is used at a position where the bed fence is linked to lift, and the first chamber 11 is inserted on an iron pipe of the bed fence to play a role in fixing the iron pipe and facilitating the lifting of the bed fence; the four first clamping grooves 12 on the lock sleeve 1 are clamped with the four first clamping blocks 21 on the fixed cover 2, so that the fixed cover 2 can be fixed in the lock sleeve 1; be equipped with stopper 14 on the second chamber 13 in the lock sleeve 1, stopper 14 and the spacing groove 22 joint on the fixed cover 2, stopper 14 and spacing groove 22's quantity is one, in the installation, at first aim at stopper 14 in the second chamber 13 with the spacing groove 22 on the fixed cover 2, insert first draw-in groove 12 with the first fixture block 21 on the fixed cover 2 again, can install and accomplish, through stopper 14 and spacing groove 22's cooperation, both easy to assemble have improved the stability between fixed cover 2 and the lock sleeve 1 again.
