[0017] The utility model has the following advantages:

[0018] 1、Adjusting the lower adjusting frame: the bed guard rail convenient to lift and disassemble is arranged on the side of the bed, the mattress presses the bottom plate, according to the thickness of the mattress, the rear end of the locking button is pressed down, the locking button spring hole is compressed, the locking pin slides out of the lifting hole, the lower sliding sleeve locking pin hole and the stand pipe locking pin hole, the lower sliding sleeve drives the stand pipe to slide up and down along the lifting rod by force, when the next horizontal rod and the second horizontal rod contact the upper surface of the mattress, the rear end of the locking button is released, the locking button spring hole is elastically driven to swing, the locking pin slides through the lower sliding sleeve locking pin hole, the stand pipe locking pin hole and is clamped into the lifting hole.

[0019] 2、Disassembling the lower adjusting frame: the rear end of the locking button is pressed down, the locking button spring hole is compressed, the locking pin slides out of the lifting hole, the lower sliding sleeve locking pin hole and the stand pipe locking pin hole, the stand pipe is lifted, the lower sliding sleeve is separated from the stand pipe; the elastic column is pressed down to pull the lower sliding sleeve outward, the lower sliding sleeve is separated from the next horizontal rod and the second horizontal rod; the lower adjusting frame is convenient to disassemble.

[0020] 3. Adjusting the upper adjustment frame: When it is necessary to lower the upper first or second crossbar, press the first and second buttons simultaneously. The button springs are compressed, pressing down the upper sliding sleeve. The upper sliding sleeve slides down along the riser, and the upper sliding sleeve drives the upper first and second crossbars to fall through the support frame and hinge frame. When it is necessary to raise the upper first or second crossbar, lift the upper sliding sleeve and slide it up along the riser. The upper sliding sleeve is compressed by the inclined surfaces of the first and second buttons. When the first and second buttons correspond to the button holes on the riser and the upper sliding sleeve, the elastic force of the button springs causes the first and second buttons to slide out of the button holes on the riser and the upper sliding sleeve, thus positioning the upper sliding sleeve with the riser. The upper sliding sleeve drives the upper first and second crossbars to rise through the support frame and hinge frame. The upper sliding sleeve is firmly positioned with the riser, and the upper first and second crossbars are easy to raise and lower.

[0021] 4. Disassembling the upper crossbar: After the upper sliding sleeve falls, lift the support frame. The support frame slide rail slides upward along the upper sliding sleeve groove. The upper sliding sleeve slide rail disengages from the support frame groove, thus separating the upper sliding sleeve from the support frame. Press the spring pin to pull the support frame outward, thus separating the hinge frame from the first and second crossbars. The first and second crossbars are easy to disassemble.

[0022] 5. The connecting plate between the first and second bed rails, which are easy to lift and disassemble, improves the stability of both bed rails. Attached Figure Description
