Description

Technical Field

[0001] The present application relates to the technical field of bed guardrails, and in particular to a three-layer folding guardrail. Background Art

[0002] In the prior art, in order to facilitate patients to get in and out of bed during use, the guardrails on both sides of the bed body are foldable structures. However, most of the existing guardrails are foldable and can be flipped outwards. This type of guardrail can only be raised and lowered by personnel outside the bed, making it impossible for patients to get in and out of bed independently. Moreover, most of the existing guardrails are single-layer or double-layer structures, and their stability and support are poor. Utility Model Content

[0003] The problem to be solved by the present application is that existing medical beds mainly use a single-layer or double-layer structure with a foldable guardrail that folds outward. However, this type of guardrail cannot be raised or lowered by the patient alone and requires the assistance of others to perform the raising or lowering operation, which not only causes inconvenience in use, but also has a problem of poor supporting stability.

[0004] In order to solve the above-mentioned technical problems, the present application provides a three-layer folding guardrail, including a guardrail body composed of a tube body, the guardrail body and the bed board of the medical bed are rotatably connected, the number of the tube bodies is multiple, and they are all detachably connected to each other, a locking member is provided between the guardrail body and the bed board for connecting the two to temporarily fix the two, and a stabilizing member is provided between the guardrail body and the bed board for connecting the two to improve stability during rotation.

[0005] Since the guardrail of the present application is designed with a guardrail body, a locking piece and a stabilizing piece, it is possible to increase the number of tube bodies to improve the protective strength of the guardrail body, realize the locking and fixing operation of the guardrail body after it is unfolded through the locking piece, and realize the stability of the guardrail body when it is rotated through the stabilizing piece, thereby solving the problem that the medical beds in the prior art mainly use a single-layer or double-layer structure that is folded outward to store and fold. However, this type of guardrail cannot be raised or lowered by the patient alone, and requires the help of others to assist in the raising or lowering operation, which not only causes inconvenience in use, but also has poor supporting stability.

DETAILED DESCRIPTION

[0017] The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application. Example

[0018] The present application relates to a three-layer folding guardrail, such as Figure 1-10As shown, the guardrail includes a guardrail body 1 composed of a tube body, and in order to facilitate the folding or unfolding operation of the guardrail body 1 when it is raised or lowered, a rotatable active connection method is adopted between the guardrail body 1 and the bed board 2 of the medical bed. Since the guardrail body 1 is stored and folded by rotating around the bed board 2, in order to realize the rotation operation of the guardrail body 1, the number of the tube bodies is multiple, and they are all detachably connected to each other. When the guardrail is raised, in order to keep it in a stable supporting state, a locking member 4 is added between the guardrail body 1 and the bed board 2 to connect the two for temporary fixing. In order to improve the stability of the guardrail body 1 when it rotates around the bed board 2, the guardrail body 1 and the bed board 2 are connected by a stabilizing member 5.

[0019] The tube body is divided into a front tube, a middle tube and a rear tube according to their arrangement positions and functions. The front tube is arranged at the front end of the tube body and can rotate around the bed board 2. The rear tube is arranged at the end of the tube body and can rotate around the bed board 2. The middle tube is arranged between the front tube and the rear tube to connect the two. Since the middle tube is rotatably connected to the front tube and the rear tube, the fence body 1 can be rotated, stored and folded around the bed board 2.

[0020] In order to improve the supporting strength of the fence body 1, the number of middle tubes is three, which are arranged in parallel with the upper, middle and lower parts side by side. According to the different arrangement positions, they are divided into upper middle tube 17, middle middle tube 18 and lower middle tube 19 of equal length. The upper middle tube 17, middle middle tube 18 and lower middle tube 19 always remain in a horizontal state.

[0021] The front pipe fitting includes a front bent pipe 6, a front rotary pipe 10, a front short pipe 9, and a front long pipe 8. The front bent pipe 6 is arranged on one side of the bed board 2. The lower end of the front bent pipe 6 is provided with a front rotary pipe 10 rotatably connected to the bed board 2. A joint pipe 7 arranged vertically and connected to one end of the upper middle pipe 17 is arranged on one side of the front bent pipe 6. In order to facilitate the connection with the middle-middle pipe 18, a front long pipe 8 for connecting to one end of the upper middle pipe 17 is arranged in the upper-middle position of the upper bent pipe, and a front short pipe 9 for connecting to one end of the lower middle pipe 19 is arranged side by side directly below the front long pipe 8, so that the connection operation with the middle pipe fitting is performed with the help of the joint pipe 7, the front long pipe 8 and the front short pipe 9.

[0022] The rear pipe fittings include a rear bent pipe 11, a rear rotary pipe 16, a rear short pipe 12, and a rear long pipe 13. The rear bent pipe 11 is arranged on one side of the bed board 2. The lower end of the rear bent pipe 11 is provided with a rear rotary pipe 16 rotatably connected to the bed board 2. The upper end of the rear bent pipe 11 is directly connected to the other end of the upper middle pipe 17. The surface of the rear bent pipe 11 is connected with a rear short pipe 12 and a rear long pipe 13 coaxially arranged with the front long pipe 8 and the front short pipe 9, respectively. The rear short pipe 12 is connected to the other end of the middle-middle pipe 18, and the rear long pipe 13 is connected to the other end of the lower middle pipe 19.

[0023] In order to prevent the front pipe, the middle pipe and the rear pipe from having dead points when rotating around the bed board 2, the length ratios of the middle pipe, the joint pipe 7, the front short pipe 9, the rear long pipe 13, the rear long pipe 13 and the rear short pipe 12 are 35.89:4.64:3.25:2.13:2.13:1, so that the front pipe, the middle pipe and the rear pipe can rotate smoothly.

[0024] In order for the locking member 4 to achieve the locking effect, a base plate 3 is fixedly arranged on the upper part of the bed rail 2, and a positioning hole 27 is provided on the upper part of the base plate 3 for achieving fixed positioning operation. In order for the fence body 1 to rotate in a stable state, a slide groove 26 is also provided on the upper part of the base plate 3 for guiding and limiting the movement direction of the fence body 1, and a sliding pin 15 that fits with the slide groove 26 is arranged at the lower end of the rear bent pipe 11, so that the fence body 1 can slide along the slide groove 26 with the help of the sliding pin 15, thereby effectively improving the stability of the fence body 1 during rotation.

[0025] The locking member 4 includes a pin rod 20, a sleeve 14, a baffle 23, and a spring 22. The sleeve 14 is arranged through the rear bent tube 11, and the pin rod 20 is sleeved inside the sleeve 14 and can slide back and forth. The front end of the pin rod 20 can penetrate into the positioning hole 27 to achieve a position locking operation. When the pin rod 20 is pulled out of the positioning hole 27, the fence body 1 can be freely rotated. In order to enable the pin rod 20 to achieve an elastic self-locking operation, a baffle 23 is arranged at the end of the pin rod 20, and a spring 22 sleeved with the pin rod 20 is arranged between the baffle 23 and the sleeve 14, so that the pin rod 20 has an elastic self-tightening ability with the help of the elastic force of the spring 22.

[0026] The stabilizing member 5 includes a fixing sleeve 21 and a retaining ring 25. The fixing sleeve 21 passes through the bottom plate 3 and is fixed thereto, and the front rotary tube 10 and the rear rotary tube 16 are respectively sleeved inside the fixing sleeve 21. With the help of the fixing sleeve 21, the front rotary tube 10 and the rear rotary tube 16 have stable supporting performance when rotating. In order to prevent the front rotary tube 10 and the rear rotary tube 16 from shaking along the axial direction of the fixing sleeve 21, a connecting member 24 for limiting the position is added between the fixing sleeve 21 and the front rotary tube 10 and the rear rotary tube 16. The connecting member 24 can be a bolt, a nut, or a rivet structure. Since both ends of the fixing sleeve 21 are open structures, a retaining ring 25 for auxiliary limiting the position is added at one end of the fixing sleeve 21.

[0027] When in use, the locking member 4 is located near the patient's chest, so that it is convenient for the patient to operate manually. When the guardrail is to be folded, it is only necessary to pull the pin rod 20 outward with one hand to disengage the pin rod 20 from the positioning hole 27, and then the rear pipe can be pushed toward the foot, so that the rear pipe will drive the middle pipe and the front pipe to rotate around the bed rail 2, and then the rotation operation of the fence 1 is realized under the action of the gravity of the fence 1 itself, and because the front pipe, the middle pipe and the rear pipe are all active connection structures and have appropriate size ratios, the fence 1 can be smoothly folded. The folding operation avoids the occurrence of dead points; and when the guardrail needs to be raised, only one hand needs to pull the rear pipe piece toward the head, and the rear pipe piece will drive the middle pipe piece and the front pipe piece to rise until the pin rod 20 is inserted into the positioning hole 27, and the guardrail deployment operation is completed. Compared with the traditional guardrail that flips outward, the convenience of the patient's independent operation is greatly improved. In the absence of others, the guardrail can be independently stored and deployed, which is convenient for users to get in and out of bed. The guardrail body 1 uses the stabilizing member 5 to achieve stability when flipping, and the increased guardrail height will not affect its folding and storage operation.
