[0029] As shown in the drawings, Figure 1 The utility model discloses a bed head turnover mechanism, including bed plate 1, the one end of bed plate 1 is provided with guardrail 2, and the bottom of guardrail 2 is provided with turnover folding mechanism 3, and turnover folding mechanism 3 is connected with the sliding telescopic mechanism 4 arranged at the bottom of bed plate 1.

[0030] As shown in the drawings, Figure 2 Turnover folding mechanism 3 includes fixed seat 301 and movable seat 302, and fixed seat 301 is connected with sliding telescopic mechanism 4, and movable seat 302 is connected with guardrail 2.

[0031] As a specific structure that can realize turnover folding mechanism 3, as shown in the drawings, Figure 3 Fixed seat 301 includes two interval arrangement fixed plates 301-1, and fixed plate 301-1 is fixedly connected with sliding telescopic mechanism 4. Movable seat 302 includes two interval arrangement movable plates 302-1, and movable plate 302-1 is fixedly connected with guardrail 2.

[0032] Among them, the side of each fixed plate 301-1 is arranged with one movable plate 302-1, and each movable plate 302-1 is connected with the corresponding fixed plate 301-1 through clamping structure 303.

[0033] As shown in the drawings, Figure 4 And 5As shown, the clamping structure 303 includes an upper positioning groove 303-1, a lower positioning groove 303-2, a guide sliding hole 303-3, a positioning pin 303-4 and a limiting pin 303-5; the upper positioning groove 303-1 is arranged at the top of the fixed plate 301-1, the guide sliding hole 303-3 is arranged at the lower part of the fixed plate 301-1, the guide sliding hole 303-3 is L-shaped, and the lower positioning groove 303-2 is arranged at the corner position of the guide sliding hole 303-3. The positioning pin 303-4 and the limiting pin 303-5 are both fixed on the movable plate 302-1.

[0034] When the guardrail 2 needs to be unfolded and erected, the positioning pin 303-4 is clamped and matched with the upper positioning groove 303-1, and at the same time, the limiting pin 303-5 is clamped and matched with the lower positioning groove 303-2. When the guardrail 2 needs to be folded and stored, the guardrail 2 is pulled upward, after the limiting pin 303-5 moves upward along the vertical part of the guide sliding hole 303-3, the limiting pin 303-5 is separated from the lower positioning groove 303-2 below, and at the same time, the positioning pin 303-4 is also separated from the upper positioning groove 303-1, then after the guardrail 2 rotates by 270 degrees (counterclockwise rotation in this embodiment), the guardrail 2 is turned to the lower side of the bed plate 1, the guardrail 2 is pushed to the inner side of the bed, so that the limiting pin 303-5 enters the guide sliding hole 303-3

[0035] horizontal part.

[0036] As shown, Figure 6 The sliding telescopic mechanism 4 includes a guide sliding sleeve 401 and a guide sliding rod 402, the guide sliding sleeve 401 is fixed at the bottom of the bed plate 1, the guide sliding rod 402 is slidingly connected in the guide sliding sleeve 401, one end of the guide sliding rod 402 is connected with the turnover folding mechanism 3, and specifically is fixed with the fixed plate 301-1 in this embodiment. By pulling the guide sliding rod 402 inward, the guardrail 2 can be completely hidden at the bottom of the bed plate 1.

[0037] In this embodiment, the guide sliding rod 402 corresponds to the fixed plate 301-1, therefore, the number of the guide sliding sleeves 401 is two, and the guide sliding rod 402 is arranged in each guide sliding sleeve 401.
