DETAILED DESCRIPTION

[0028] In order to make the technical problems, technical solutions and beneficial effects to be solved by the present invention more clearly understood, the present invention is further described in detail below in conjunction with the accompanying drawings and embodiments.

[0029] like Figure 1 As shown, in this embodiment, a bedside flipping mechanism is disclosed, comprising a bed board 1, a guardrail 2 is arranged at one end of the bed board 1, a flipping and folding mechanism 3 is arranged at the bottom of the guardrail 2, and the flipping and folding mechanism 3 is connected to a sliding and telescopic mechanism 4 arranged at the bottom of the bed board 1. The flipping and folding mechanism 3 drives the guardrail 2 to flip to the bottom of the bed board 1, and then the sliding and telescopic mechanism 4 drives the sliding and telescopic mechanism 4 and the guardrail 2 to move toward the inner side of the bed board 1 as a whole, thereby realizing that the guardrail 2 is completely hidden at the bottom of the bed board 1.

[0030] like Figure 2 As shown, the flipping and folding mechanism 3 includes a fixed seat 301 and a movable seat 302 , the fixed seat 301 is connected to the sliding and telescopic mechanism 4 , and the movable seat 302 is connected to the guardrail 2 ; the fixed seat 301 and the movable seat 302 are rotatably connected via a clamping structure 303 .

[0031] As a specific structure that can realize the flipping and folding mechanism 3, as Figure 3 As shown, the fixed seat 301 includes two fixed plates 301 - 1 arranged at intervals, and the fixed plates 301 - 1 are fixedly connected to the sliding telescopic mechanism 4 . The movable seat 302 includes two movable plates 302 - 1 arranged at intervals, and the movable plates 302 - 1 are fixedly connected to the guardrail 2 .

[0032] A movable plate 302 - 1 is arranged on the side of each fixed plate 301 - 1 , and each movable plate 302 - 1 is connected to the corresponding fixed plate 301 - 1 via a clamping structure 303 .

[0033] like Figure 4 and 5As shown, the clamping structure 303 includes an upper positioning groove 303-1, a lower positioning groove 303-2, a guide slide hole 303-3, a positioning pin 303-4 and a limit pin 303-5; the upper positioning groove 303-1 is arranged at the top of the fixed plate 301-1, the guide slide hole 303-3 is arranged at the lower part of the fixed plate 301-1, the guide slide hole 303-3 is L-shaped, and the guide slide hole 303-3 is provided with a lower positioning groove 303-2 at the corner position. The positioning pin 303-4 and the limit 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 engages with the upper positioning groove 303-1, and at the same time, the limit pin 303-5 engages with the lower positioning groove 303-2. When the guardrail 2 needs to be folded and stowed, the guardrail 2 is pulled upward, and the limit pin 303-5 moves upward along the vertical part of the guide slide hole 303-3, and the limit pin 303-5 is disengaged from the lower positioning groove 303-2 below. At the same time, the positioning pin 303-4 is also disengaged from the upper positioning groove 303-1, and then the guardrail 2 is rotated 270 degrees (counterclockwise in this embodiment), and the guardrail 2 is turned over to the bottom of the bed board 1, and the guardrail 2 is pushed toward the inside of the bed, so that the limit pin 303-5 enters the horizontal part of the guide slide hole 303-3.

[0035] like Figure 6 As shown, the sliding telescopic mechanism 4 includes a guide sliding sleeve 401 and a guide sliding rod 402. The guide sliding sleeve 401 is fixed to the bottom of the bed board 1. The guide sliding rod 402 is slidably connected in the guide sliding sleeve 401. One end of the guide sliding rod 402 is connected to the flipping and folding mechanism 3, specifically fixed to 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 board 1.

[0036] In this embodiment, the guide slide rod 402 corresponds to the fixed plate 301-1, so there are two guide slide sleeves 401, and each guide slide sleeve 401 is provided with a guide slide rod 402. Both the guide slide sleeve 401 and the guide slide rod 402 are cylindrical structures.

[0037] In this embodiment, a magnetic block 403 is provided at one end of the guide rod 402 away from the flipping and folding mechanism 3, and the magnetic block 403 cooperates with a magnet assembly 404, and the magnet assembly 404 is fixed to the bottom of the bed board 1. When the guide rod 402 is pulled inward to drive the guardrail 2 to be completely hidden at the bottom of the bed board 1, the magnetic block 403 is attracted to the magnet assembly 404, thereby fixing the sliding and telescopic mechanism 4 to prevent the guardrail 2 from extending.

[0038] It should be noted that when the guardrail 2 needs to be unfolded and erected, the guide slide rod 402 is pulled outward, and the magnetic block 403 at the end of the guide slide rod 402 abuts against the guide slide sleeve 401, limiting the maximum distance that the guide slide rod 402 can be pulled outward.

[0039] In this embodiment, a guardrail hanger 5 is provided at the bottom of the bed board 1, and the guardrail hanger 5 is hung in coordination with the guardrail 2. Figure 7 As shown, when the guardrail 2 is folded and retracted, the magnetic block 403 and the magnet assembly 404 are attracted and matched in place, and the guardrail hanging seat 5 can limit the position of the guardrail 2.

[0040] In this embodiment, a locking top screw 501 is threadedly connected to the guardrail hanger 5 , and the locking top screw 501 is in contact with the guardrail 2 .

[0041] The embodiments described above are only descriptions of the preferred modes of the present invention, and are not intended to limit the scope of the present invention. Without departing from the design spirit of the present invention, various modifications and improvements made to the technical solutions of the present invention by ordinary technicians in this field should all fall within the protection scope determined by the claims of the present invention.
