Technical Field

[0001] The utility model relates to the structure of a bed guardrail and belongs to the field of medical equipment. Background Art

[0002] Rehabilitation beds are essential medical devices for rehabilitation treatment. They are used for patient diagnosis, rest, injections, and postoperative rehabilitation. In order to adapt to the patient's needs and prevent the patient from rolling off the bed and improve its safety performance, guardrails are often required. That is, guardrails are often installed on both sides of the hospital bed or rehabilitation bed. However, the guardrails in the prior art are mostly fixedly connected to the two sides of the bed with bolts, which are inconvenient to install and disassemble, and the installation position is not flexible enough. The position of the guardrail cannot be flexibly adjusted according to the patient's needs. Especially when it is inconvenient for the patient to get in and out of bed, or other instruments need to be placed, due to the limited space in the ward, if the position of the guardrail cannot be flexibly adjusted, it is easy to cause bumps, or the items and instruments are not placed reasonably in the narrow space, wasting space, affecting operation, etc.

However, it should be understood that these descriptions are only exemplary and are not intended to limit the scope of the utility model. In addition, in the following description, the description of well-known structures and technologies is omitted to avoid unnecessary confusion of the concept of the utility model.

[0025] The connection mentioned in the present invention is divided into fixed connection and detachable connection. The fixed connection is a non-detachable connection, including but not limited to conventional fixed connection methods such as folding connection, rivet connection, bonding connection and welding connection. The detachable connection includes but is not limited to conventional detachable methods such as threaded connection, snap connection, pin connection and hinge connection. When the specific connection method is not clearly defined, it is assumed that at least one connection method can always be found in the existing connection methods to achieve the function. Those skilled in the art can choose according to their needs. For example: choose welding connection for fixed connection and hinge connection for detachable connection.

[0026] Specific implementation method 1: Combination Figure 1-Figure 10 The present embodiment is described. The structure of the bed guardrail of the present embodiment comprises a slide rail 1, a slider 2, a locking device 3 and a folding guardrail 4. The slide rail 1 is fixedly mounted on both sides of the bed. The slider 2 is fixedly mounted with a folding guardrail 4. The slider 2 is slidably mounted in the slide rail 1 and is fixedly connected with the slide rail 1 through the locking device 3. The locking device 3 comprises a fixing plate 31, a sliding shaft 32, a spring 33, a bottom plate 34 and a locking hole 35. The slide rail 1 is processed with a slide groove 11 that runs through the top and bottom. The top of the sliding shaft 32 is hingedly mounted with a fixing plate 31. The bottom of the sliding shaft 32 is fixedly connected with the bottom plate 34 through a spring 33. The bottom of the bottom plate 34 is provided with a locking hole 35. The slider 2 is provided with at least two storage grooves 21 that run through the top and bottom. At the same time, a locking groove 22 that passes through the front side wall of the slider 2 and is vertically and horizontally arranged is processed below the storage groove 21. The front end surface of the fixing plate 31 and the top end surface of the bottom plate 34 are both attached with an anti-slip rubber layer.

[0027] The locking device 3 of this embodiment can be in two use states, including an adjustment state of the folding guardrail 4 and a locking state of the locking device 3;

[0028] When the folding guardrail 4 is in the adjustment state, that is, when the spring 33 is compressed, the fixing plate 31 and the sliding shaft 32 do not flip over, the lateral direction of the front end surface of the fixing plate 31 is set parallel to the sliding direction of the slide rail 1, and the fixing plate 31 and the bottom plate 34 are completely placed in the storage groove 21, the locking hole 35 at the bottom of the bottom plate 34 is aligned with the locking groove 22, and is temporarily fixed and connected by the pin 36. At this time, the locking device 3 is completely retracted and placed in the storage groove 21, which does not affect the installation and disassembly of the slide rail 1 and the slider 2;

[0029] When the locking device 3 is in the locked state, the pin 36 is pulled out, and when the spring 33 is stretched, the locking device 3 is rotated 90 degrees as a whole, and the fixed plate 31 and the sliding shaft 32 are flipped. The axes of the fixed plate 31 and the sliding shaft 32 are perpendicular to each other. The fixed plate 31 passes through the slide groove 11 at the top of the slide rail 1, and the front end surface of the fixed plate 31 fits with the top end surface of the slide rail 1, and the lateral direction of the front end surface of the fixed plate 31 is set perpendicular to the sliding direction of the slide rail 1. The bottom plate 34 passes through the slide groove 11 at the bottom of the slide rail 1, and the top end surface of the bottom plate 34 fits with the bottom end surface of the slide rail 1. At this time, due to the tension of the spring 33, the fixed plate 3 The anti-skid rubber layer attached to the front end surface of 1 and the top end surface of the bottom plate 34 clamps the slide rail 1 tightly. At the same time, the top end surface of the slide rail 1 is located on both sides of the slide groove 11 and is processed with two rows of threaded holes 12 arranged side by side. The fixing plate 31 is processed with a locking through hole 311. The locking through hole 311 of the fixing plate 31 is fixedly connected with the threaded hole 12 through a bolt, so that the locking device 3 is fixed in any threaded hole 12, thereby making the folding guardrail 4 fixedly connected to the bed body. It should be noted that the threaded hole 12 plays a further positioning role when the bolt connected to it plays a fixing role when only the fixing plate 31 and the bottom plate 34 are tightened.

[0030] The slide rail 1 is a U-shaped slide rail with openings facing the left and right sides of the bed body. When the spring 33 is compressed, the slide rail 1 and the slider 2 can be quickly disassembled and installed.

[0031] The folding guardrail 4 includes a mounting frame 41, a flip frame 42, a connecting frame 43, a bottom shell 44, a hand buckle 45, a hook 46, a clamping shaft 47, a pull rod 48 and a guardrail 49. The mounting frame 41 is fixedly installed on the front side of the slider 2, and both ends of the flip frame 42 and the connecting frame 43 are respectively hinged to the mounting frame 41 and the guardrail 49, and the bottom of the connecting frame 43 is installed with a bottom shell 44, one end of the hand buckle 45 is clamped through the bottom shell 44 and placed on the outside, and the other end of the hand buckle 45 is installed with a hook 46, and a clamping shaft 47 is provided at the bottom of the flip frame 42, and both ends of the pull rod 48 are respectively hinged to the mounting frame 41 and the connecting frame 43, and the guardrail 49 can be pulled up or down by manually pulling the hand buckle 45, and the pull rod 48 will stretch or shrink accordingly, and when the clamping shaft 47 is clamped and connected with the hook 46, the state of the guardrail 49 is fixed.
