[0038] During specific use, the length of the guardrail is adjusted according to the length of the bed body 1 to make it adapt to the bed body 1, and the main support frame 3 and the fence support 2 are fixed by the L-shaped clamp 71. By rotating the push rod 73, the push rod 73 drives the clamping column 72 to rotate, so that the end of the clamping column 72 is locked with the clamping groove at the end of the L-shaped clamp 71, and finally the main support frame 3 is fixed. Further, by adjusting the distance between the connecting rod 51 and the sliding frame 52, after the adjustment is completed, the block 55 set at the bottom of the sliding frame 52 is locked with the clamping hole 53 set at the bottom of the connecting rod 51, so as to achieve the adjustment and fixation of the position of the main support frame 3 and the auxiliary support frame 4 at the bottom of the guardrail.

[0039] Furthermore, the height adjustment assembly 8 includes a telescopic frame 81 and a telescopic frame 82 slidably connected to the top of the main support frame 3, and a telescopic frame 82 slidably connected to the top of the auxiliary support frame 4.

The telescopic frame 82 and the auxiliary support frame 4 are fixed by a locking assembly 10, and the telescopic frame 81 and the top of the telescopic frame 82 are slidably connected with a folding and rotating assembly 6.

[0040] It should be noted that the telescopic frame 82 is a frame structure, so that the telescopic frame 82 will not be blocked by the L-shaped clamp 71 and the clamp column 72 during the sliding downward adjustment process.

[0041] As an example, the limiting component 9 includes an elastic sheet 91 fixedly connected to the telescopic frame 81, and both ends of the elastic sheet 91 are fixedly connected to limiting blocks 92. Each of the limiting blocks 92 slides through the side wall of the telescopic frame 81 and cooperates with the limiting holes 93 arranged on both sides of the main support frame 3; the locking component 10 includes a spring B101 connected to both sides of the bottom of the telescopic frame 82, and the ends of the spring B101 are connected to locking columns 102, and the locking columns 102 cooperate with the locking grooves 103 arranged on both sides of the top of the auxiliary support frame 4.

[0043] During the specific operation process, the storage component 11, the telescopic rod 63 and the connecting rod 62 can be flipped, so as to make the storage component 11, the telescopic rod 63 and the connecting rod 62 be on the same vertical plane as the main support frame 3 and the auxiliary support frame 4. It can make the storage component 11 slide onto the support plate 83 arranged in the telescopic frame 81, and the cross bar 64 is rotatably connected through a rotating shaft, so that the guardrail can be folded forward and backward, and thus it is suitable for the angle change of the bed body bending. Embodiment 2

[0044] On the basis of Embodiment 1, referring to Figure 1-17 As shown, in order to facilitate placing tools and items on the guardrail, a storage component 11 is arranged on the guardrail. Specifically, the storage component 11 includes two hollow convex blocks 111 that are rotatably connected. A C-shaped groove 112 is formed through the upper surface of each convex block 111. A C-shaped plate 113 is slidably arranged in the C-shaped groove 112, and a storage tray 114 is placed between the two C-shaped plates 113.

[0045] Furthermore, a lever 115 is rotatably connected to the front and rear inner walls of each C-shaped plate 113. A heavy object block 116 is rotatably connected to the end of the lever 115. A lever shaft 117 is fixedly connected to the middle of the lever 115. An activity groove 118 is formed on one side inner wall of the convex block 111, and the lever shaft 117 is matched with the activity groove 118.

[0046] During the specific operation process, the heavy object block 116 in the convex block 111 drives the lever 115 to rotate around the lever shaft 117, so that the lever 115 drives the C-shaped plate 113 to move upward along the C-shaped groove 112, thus facilitating placing the storage tray 114 between the C-shaped plates 113; when it is necessary to contract the guardrail, remove the storage tray 114, press the C-shaped plate 113, so that the C-shaped plate 113 moves downward and contracts along the C-shaped groove 112, and flip the convex block 111, so that the lever 115 is flipped synchronously, so that the lever 115 will not rotate driven by the heavy object block 116. Embodiment 3

[0047] On the basis of Embodiment 1 and Embodiment 2, referring to Fig. 9 、 16 -17 shown, in order to further restrain and limit the patient, a restraint component 12 is arranged on the guardrail.

[0048] Specifically, a restraint component 12 is arranged on the convex block 111. The restraint component 12 includes a reel 121 arranged on two convex blocks 111 on one side. A restraint belt 122 is wound on the reel. An insertion plate 123 is arranged at the end of each restraint belt. A slot 124 is formed in the insertion plate 123, and the slot 124 is matched with an insertion piece 125 arranged on the convex block 111 on the other side.

[0049] The further restraint of the patient can be achieved through the restraint belt 122. The combination of the guardrail and the restraint belt 122 effectively ensures the safety of the patient. Specific operation process

[0050] Now, in combination with Embodiment 1, Embodiment 2, and Embodiment 3, the operation process of a retractable and bendable guardrail for an operating bed in the actual application process of the present application will be specifically described: Adjust the length of the guardrail according to the length of the bed body 1 to make it fit the bed body 1. Fix the main support frame 3 and the fence support 2 through the L-shaped fastener 71. By rotating the push rod 73, the push rod 73 drives the clamping column 72 to rotate, so that the end of the clamping column 72 is locked with the card slot at the end of the L-shaped fastener 71, and finally the fixation of the main support frame 3 is realized. Further, by adjusting the distance between the connecting rod 51 and the sliding frame 52, after the adjustment is completed, the card block 55 provided at the bottom of the sliding frame 52 is matched and locked with the card hole 53 provided at the bottom of the connecting rod 51 to realize the adjustment and fixation of the positions of the main support frame 3 and the auxiliary support frame 4 at the bottom of the guardrail.

[0051] Flip the convex block 111 so that the convex block 111 is in a horizontal state. At this time, under the action of the heavy object block 116, the lever 115 is driven to rotate around the lever shaft 117, so that the lever 115 drives the U-shaped plate 113 to move upward along the U-shaped groove 112, which is convenient for placing the storage tray 114 between the U-shaped plates 113, and finally realizes the installation and fixation of the whole guardrail.

[0052] The cross bars 64穿设 on adjacent two convex blocks 111 are rotationally connected through a rotating shaft, which can realize the corresponding bending of the guardrail when the bending angle of the bed body 1 changes, improving its applicability.

[0053] When the guardrail is not needed, remove the storage tray 114, press the U-shaped plate 113, so that the U-shaped plate 113 moves downward and contracts along the U-shaped groove 112, and flip the convex block 111, so that the lever 115 is flipped synchronously, so that the lever 115 will not rotate driven by the heavy object block 116.

[0054] During the rotation of the convex block 111, the connecting rod 62 and the telescopic rod 63 are driven to rotate synchronously. Finally, all components are in the same vertical plane. By pressing the telescopic rod 63 and the convex block 111, the connecting rod 62 and the telescopic rod 63 move downward along the telescopic frame 81, and the sliding block 61 moves downward along the telescopic frame 82. During the movement, the clamping position column 102 is released from the restriction with the clamping position groove 103 under the action of the spring B101, and finally the sliding block 61 slides to the support plate 83 provided in the telescopic frame 81.

[0055] It should be noted that there may be some inaccuracies in the translation of some terms due to the lack of specific context. You can adjust them according to the actual situation.Furthermore, during the continuous pressing process, the telescopic frame 81 and the telescopic frame 82 slide downward along the main support frame 3 and the auxiliary support frame 4 respectively. At this time, under the action of the elastic sheet 91, the restriction between the limit block 92 and the limit hole 93 is released, and the height adjustment of the guardrail is finally achieved. The height of the adjusted guardrail does not exceed the height of the bed surface, and will not affect the medical staff in performing surgical operations.

[0056] It should be pointed out that for those skilled in the art, several modifications and improvements can be made without departing from the structure of the present invention, which should also be regarded as the protection scope of the present invention, and these will not affect the effect of the implementation of the present invention and the practicality of the patent. The protection scope required by this application shall be based on the content of its claims, and the specific implementation methods and other records in the specification can be used to interpret the content of the claims.
