Description

Technical Field

[0001] This utility model relates to the field of bed technology, and in particular to a telescopic guardrail mechanism and a bed. Background Technology

[0002] A bed generally consists of a bed frame and a mattress. The mattress is placed on the bed frame. Depending on the user's different needs, the mattress may need to be replaced. However, because mattresses vary in size, they may not fit the original bed frame well, resulting in the mattress not being able to be fixed in place. To address this issue, related technologies have proposed placing a baffle on the bed frame and elastically connecting the baffle to the bed frame using springs, allowing the baffle to move on the bed frame to accommodate mattresses of different sizes. However, in the above solutions, the springs are often exposed, which can easily cause interference, resulting in the baffle not moving smoothly and reducing the user experience. Utility Model Content

[0003] The purpose of this utility model is to provide a telescopic guardrail mechanism and bed to solve the problem of springs being easily interfered with.

[0004] To achieve this objective, the present invention adopts the following technical solution:

[0005] A telescopic guardrail mechanism is provided, comprising:

[0006] The support member is provided with a receiving cavity;

[0007] A guardrail component, comprising a guardrail body and a connecting rod, wherein the connecting rod passes through the cavity wall of the receiving cavity to allow the guardrail body to move relative to the support member; a blocking member is provided on the connecting rod and the blocking member is disposed within the receiving cavity;

[0008] An elastic element is disposed within the receiving cavity, one end of which is constrained on the connecting rod, and the other end is constrained on the inner wall of the receiving cavity.

[0009] In some embodiments, a blocking member is provided on the connecting rod, and the blocking member is disposed within the receiving cavity; the elastic member is constrained between the blocking member and the inner wall of the receiving cavity.

[0010] In some embodiments, the inner wall of the receiving cavity and / or the blocking member is provided with a buffer pad, and when the elastic member resets the blocking member, the blocking member and the inner wall of the receiving cavity can clamp the buffer pad.

[0011] In some embodiments, the elastic element is a spring, which is sleeved on the connecting rod.

[0012] In some embodiments, the support member is a box with an open top, the connecting rod passes through the opposite side wall of the box, the guardrail body covers the opening of the box and is connected to one end of the connecting rod, and the other end of the connecting rod is provided with a limiting head, which can prevent the connecting rod from detaching from the support member.

[0013] In some embodiments, the guardrail body includes a first plate and a second plate, the first plate and the second plate being set at an angle, the second plate covering the opening of the box body, and an extension plate being provided on the side of the second plate away from the first plate, the connecting rod being connected to the extension plate.

[0014] In some embodiments, there is a gap between the second plate and the open end face of the box body.

[0015] In some embodiments, the telescopic guardrail mechanism further includes a fixing member, through which the support member can be fixed to an external component.

[0016] In some embodiments, the support member is provided with a first connecting hole, and the fastener can pass through the first connecting hole to connect to the external component.

One end of the elastic element is restricted to the connecting rod, and the other end is restricted to the inner wall of the receiving cavity. Thus, when the guardrail body is subjected to an external force that causes the connecting rod to move, the elastic element can accumulate potential energy. When the external force is lost, the elastic element drives the guardrail body to return to its original position. During this period, the elastic element remains within the receiving cavity, preventing interference and avoiding problems with smooth movement caused by interference, thereby improving the user experience.

[0037] The technical solution of this utility model will be further described below with reference to the accompanying drawings and specific embodiments.

[0038] like Figures 1 to 5 As shown, this utility model provides a telescopic guardrail mechanism 10 for adapting to and adjusting mattresses of different sizes. The telescopic guardrail mechanism 10 includes a support member 1, a guardrail member 2, and an elastic member 3. The support member 1 is provided with a receiving cavity 11. The guardrail member 2 includes a guardrail body 21 and a connecting rod 22. The connecting rod 22 passes through the cavity wall of the receiving cavity 11 and is movably connected to the support member 1, thereby allowing the guardrail body 21 to move relative to the support member 1. The elastic member 3 is disposed in the receiving cavity 11. One end of the elastic member 3 is restricted to the connecting rod 22, and the other end is restricted to the inner wall of the receiving cavity 11.

[0039] The guardrail body 21 moves on the support member 1 via the connecting rod 22. The support member 1 has a receiving cavity 11, and the elastic member 3 is disposed in the receiving cavity 11. One end of the elastic member 3 is restricted to the connecting rod 22, and the other end is restricted to the inner wall of the receiving cavity 11. Thus, when the guardrail body 21 is subjected to an external force that drives the connecting rod 22 to move, the elastic member 3 can accumulate potential energy. When the external force is lost, the elastic member 3 drives the guardrail body 21 to return to its original position. During this period, the elastic member 3 remains in the receiving cavity 11, which will not cause interference and will not cause problems with movement due to interference, thus improving the user experience.

[0040] To limit the elastic element 3, in some embodiments, a blocking element 221 is provided on the connecting rod 22, and the blocking element 221 is disposed within the receiving cavity 11; the elastic element 3 is disposed within the receiving cavity 11, and the elastic element 3 is limited between the blocking element 221 and the inner wall of the receiving cavity 11. For example, one end of the elastic element 3 is fixedly connected to the blocking element 221, and the other end is fixedly connected to the inner wall of the receiving cavity 11; or both ends of the elastic element 3 abut against the blocking element 221 and the inner wall of the receiving cavity 11, respectively. In the current embodiment, the elastic element 3 can be a spring, which abuts against the blocking element 221 and the inner wall of the receiving cavity 11. To maintain the stability of the elastic element 3 during compression and reset, the spring can be sleeved on the connecting rod 22. In other alternative embodiments, the elastic element 3 can also be arranged parallel to the connecting rod 22.

[0041] like Figure 2 As shown, in some embodiments, for ease of disassembly, the blocking member 221 is detachably mounted on the connecting rod 22, allowing the connecting rod 22 to be pulled out of the receiving cavity 11 after the blocking member 221 is removed. Exemplarily, the blocking member 221 is a screw, and the connecting rod 22 has a screw hole, into which the screw is screwed, thereby abutting one end of the elastic member 3. It is understood that in other alternative embodiments, the blocking member 221 may also be welded to or integrally formed with the connecting rod 22.

[0042] like Figure 2 As shown, in some embodiments, the inner wall of the receiving cavity 11 and / or the blocking member 221 are provided with a buffer pad 4, so that when the elastic member 3 resets the blocking member 221, the buffer pad 4 can be clamped between the blocking member 221 and the inner wall of the receiving cavity 11, reducing noise. In the current embodiment, the buffer pad 4 is provided on the inner wall of the receiving cavity 11. It can be understood that since the connecting rod 22 needs to pass through the receiving cavity 11 through a through hole provided on the cavity wall of the receiving cavity 11, a buffer sleeve can also be provided in the through hole, and the connecting rod 22 passes through the buffer sleeve, thereby reducing the frictional noise generated by the connecting rod 22 and the hole wall of the through hole. Based on this, for easy fixation, the buffer sleeve can be integrally formed with the buffer pad 4.

[0043] like Figure 2As shown, in some embodiments, the support member 1 is a box with an open top. Exemplarily, the box is a U-shaped box, with both ends of the connecting rod 22 penetrating the opposite sidewalls of the box, thus providing the connecting rod 22 with two stable support points. The guardrail body 21 covers the opening of the box. To limit the connecting rod 22 and prevent it from disengaging from the through hole during resetting, one end of the connecting rod 22 is connected to the guardrail body 21, while the other end is provided with a limiting head 5. During the movement of the connecting rod 22, the limiting head 5 can abut against the support member 1 to prevent the connecting rod 22 from disengaging. It is understood that a buffer pad 4 can also be provided on the limiting head 5 and the outer wall of the support member 1, specifically in the same way as the buffer pad 4 at the blocking member 221, which will not be described further. Furthermore, to allow the connecting rod 22 to be pulled out, the limiting head 5 can be detachably connected to the connecting rod 22. For example, the limiting head 5 can be, but is not limited to, a nut, and the connecting rod 22 has threads to screw the aforementioned nut on.

[0044] like Figure 3 and Figure 4 As shown, in some embodiments, the guardrail body 21 includes a first plate 211 and a second plate 212. The second plate 212 covers the opening of the box body. The first plate 211 and the second plate 212 are set at an angle, so that the second plate 212 is used to support the mattress, while the first plate 211 is used to abut against the edge of the mattress, thereby limiting the mattress. In the current embodiment, the first plate 211 and the second plate 212 are set perpendicularly. In order to facilitate the connection of the connecting rod 22, an extension plate 213 is provided on the side of the second plate 212 away from the first plate 211. The connecting rod 22 is connected to the extension plate 213. At the same time, when the guardrail body 21 moves relative to the support member 1, the extension plate 213 can abut against the support member 1, thereby limiting the movement distance of the guardrail body 21. By limiting the stroke, excessive compression on the elastic member 3 is reduced.

[0045] like Figure 2 As shown, in the current embodiment, there is a gap between the second plate 212 and the open end face of the box. The gap between the two can prevent the second plate 212 from rubbing against each other when it moves relative to the box. This facilitates adjustment and also avoids friction noise.

[0046] Based on the gap between the second plate 212 and the upper end face of the box, multiple connecting rods 22 can be set to enhance the stability of the support.

[0047] like Figure 3 and Figure 4As shown, in some embodiments, the telescopic guardrail mechanism 10 is further provided with a fixing member 6, and the support member 1 is fixed to an external component, such as the bed frame 20, by the fixing member 6. Exemplarily, the support member 1 is provided with a first connecting hole 12, through which the fixing member 6 can pass to connect to the external component. In the current embodiment, the first connecting hole 12 is located on the bottom wall of the box body, and the fixing member 6 can be, but is not limited to, bolts or screws, thereby fixing the support member 1 to the external component. In other alternative embodiments, the fixing member 6 can also be a plug rod or a locking block, etc. Based on the provision of the first connecting hole 12 on the box body, the second plate 212 is provided with a second connecting hole 214 that mates with the first connecting hole 12, so that the fixing member 6 located at the first connecting hole 12 can be screwed on from above through the second connecting hole 214 for easy installation.

[0048] like Figure 5 As shown, this application also provides a bed, which includes a bed body 20 and the aforementioned telescopic guardrail mechanism 10. At least one telescopic guardrail mechanism 10 is provided. For example, one can be provided and installed at the foot of the bed body 20; two can be provided and installed on both sides of the bed body 20; or three can be provided and installed at the foot and both sides of the bed body 20. Thus, by adjusting the position of the guardrail 2, it can be adapted to mattresses of different sizes.

[0049] Obviously, the above embodiments of this utility model are merely examples for clearly illustrating the present utility model, and are not intended to limit the implementation of the present utility model. Those skilled in the art can make other variations or modifications based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations here.
