For disassembly, the operation is reversed. Due to the presence of the elastic member seat and the elastic member, the crossbar can adaptively adjust the length of its extension into the sliding sleeve, making the size easy to control, requiring low precision, and allowing for quick and easy installation.

Description

Technical Field

[0001] The present invention relates to the technical field of assembly structures, and in particular to a guardrail connecting mechanism and a guardrail bed. Background Art

[0002] A guardrail bed is a type of bed consisting of a bed frame and guardrails connected to the edge of the bed frame. It can prevent people from turning over and falling off the bed while sleeping. The guardrails usually include longitudinal uprights and transverse crossbars. Currently, the crossbars of bed guardrails on the market are generally assembled by plug-in assembly, and the size is difficult to control, making installation very inconvenient. Summary of the Invention

[0003] In order to solve the above problems, the present invention aims to propose a guardrail connecting mechanism and a guardrail bed to achieve the purpose of adaptive length adjustment, easy size control, low precision requirements, and convenient and quick installation.

[0004] To achieve the above object, the technical solution of the present invention is achieved as follows:

[0005] A guardrail connection mechanism includes a support seat, a sliding sleeve, an elastic member seat and an elastic member; the support seat is provided with a concave cavity, the front end of the sliding sleeve is provided with a boss, the boss is detachably mounted in the concave cavity, the elastic member seat is slidably installed in the sliding sleeve, and the elastic member is arranged in the sliding sleeve and is located in front of the elastic member seat.

[0006] When in use, first install the support seat on the first component to be installed, such as the vertical pole of the guardrail, and then insert the second component to be installed, such as the horizontal bar of the guardrail, into the sliding sleeve from the rear end. The sliding sleeve can slide back and forth within a certain range relative to the horizontal bar. During installation, compress the elastic part to make the sliding sleeve retreat, and then insert the boss into the concave cavity. After the external force is lost, the boss will be firmly embedded in the concave cavity under the action of the elastic part, realizing the connection between the two components. When disassembling, just reverse the operation. Due to the presence of the elastic part seat and the elastic part, the horizontal bar can adaptively adjust the length of extending into the sliding sleeve. The size is easy to control, the precision requirement is low, and the installation is convenient and quick.

[0007] Furthermore, the boss includes a limiting portion and a supporting portion distributed front and back, the limiting portion having a larger cross-sectional dimension than the supporting portion, a mounting opening for the limiting portion to enter the concave cavity is provided on the side of the support seat, and a clearance opening is provided at the rear end of the support seat for allowing the supporting portion to move out of position when the limiting portion enters the concave cavity, and the clearance opening forms a limiting fit with the limiting portion. With this design, the boss enters the concave cavity not along its axial direction, but along its radial direction. Since the clearance opening forms a limiting fit with the limiting portion, after installation, the boss cannot escape from the concave cavity through the clearance opening along its axial direction, thereby increasing the stability of the connection.

[0008] Furthermore, a plug post is provided at the front end of the boss, and a socket is provided on the bottom wall of the cavity. The plug post is inserted into the socket. The dimensions of the cavity and the mounting opening are such that the limiting portion and the plug post can be inserted simultaneously. During installation, the elastic member is first compressed to retract the sliding sleeve, and the limiting portion and the plug post are extended into the cavity from the mounting opening. The elastic member is then released. Under the action of the elastic member, the limiting portion moves toward the bottom of the cavity, and the plug post is inserted into the socket. With this design, the boss cannot radially escape from the cavity from the mounting opening due to the mutual interference between the plug post and the socket, thereby achieving bidirectional limiting and greatly increasing the stability of the connection.

[0009] Furthermore, the cross section of the limiting portion matches the cross section of the cavity. With this design, the limiting portion fits closely to the cavity wall, which can reduce shaking and provide greater stability.

[0010] Furthermore, the cross section of the limiting portion and the cross section of the cavity are square. This design prevents the two from rotating relative to each other, improves stability, and more importantly, the boss can be installed in the cavity in any direction of 90 degrees or 180 degrees, thus expanding its scope of use.

[0011] Furthermore, the support base includes a connecting portion and a cylindrical mounting portion, the concave cavity is formed in the connecting portion, the insertion hole is connected to the cylindrical mounting portion, and the insertion column extends into the cylindrical mounting portion. With this design, the component to be installed, such as the vertical pole of the guardrail, can be inserted into the cylindrical mounting portion, making installation more convenient and quick. In addition, the insertion column can be inserted into the vertical pole to further secure the pole.

[0012] Furthermore, a reinforcing rib is connected between the connecting portion and the cylindrical mounting portion to increase the structural strength and stability of the support seat.

[0013] Furthermore, the sliding sleeve is provided with one or more limiting structures, each comprising a suspended spring piece formed by a U-shaped groove in the sliding sleeve and a buckle disposed on the inner side of the spring piece. This design allows the spring piece formed by the U-shaped groove to have a certain degree of elasticity, allowing the buckle to be fastened to the second component to be mounted, such as a guardrail crossbar with a limiting hole in the crossbar. When the crossbar enters the sliding sleeve, the crossbar squeezes the spring piece and the buckle, causing them to bend outward. When the crossbar slides to the limiting hole, the spring piece returns to its original position, and the buckle enters the limiting hole, securing the crossbar in place.

[0014] Furthermore, a mounting post is provided at the front end of the elastic member seat, a mounting hole is provided in the boss, one end of the elastic member is sleeved on the mounting post, and the other end is inserted into the mounting hole. This design is not only convenient for installation, but also makes the elastic member less likely to shake and more stable.

[0015] In order to achieve the above-mentioned purpose, the present invention also provides a guardrail bed, comprising a bed body and a guardrail, wherein the guardrail is installed using the above-mentioned guardrail connecting mechanism.

[0016] The advantages of the guardrail bed and the above-mentioned guardrail connecting mechanism over the prior art are the same and will not be repeated here. BRIEF DESCRIPTION OF THE DRAWINGS

[0035] The present invention will be described in detail below with reference to the accompanying drawings and in conjunction with embodiments.

[0036] It should be noted that the embodiments described are only some of the embodiments of the present invention, rather than all of the embodiments. In the absence of conflict, the embodiments in this application and the features in the embodiments may be combined with each other. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present invention.

[0037] If the embodiments of the present invention involve directional indications (such as up, down, left, right, front, back, etc.), such directional indications are only used to explain the relative positional relationship, movement, etc. between the components under a certain specific posture (as shown in the accompanying drawings). If the specific posture changes, the directional indication will also change accordingly.

[0038] In addition, if there are descriptions involving "first," "second," etc. in the embodiments of the present invention, such descriptions are for descriptive purposes only and should not be understood as indicating or implying their relative importance or implicitly specifying the number of the technical features indicated. Therefore, features specified as "first," "second," etc. may explicitly or implicitly include at least one of such features.

[0039] See also Figures 1 to 4 To facilitate understanding of the present invention, Figure 1 The coordination with the vertical and horizontal bars of the guardrail is shown in FIG.

[0040] A guardrail connection mechanism according to an embodiment of the present invention includes a support seat 1, a sliding sleeve 2, an elastic member seat 3 and an elastic member 4; a concave cavity 13 is provided on the support seat 1, a boss 21 is provided at the front end of the sliding sleeve 2, and the boss 21 is removably mounted in the concave cavity 13, the elastic member seat 3 is slidably installed in the sliding sleeve 2, and the elastic member 4 is arranged in the sliding sleeve 2 and located in front of the elastic member seat 3.

[0041] When in use, first install the support seat on the component to be installed, such as the vertical pole 5 of the guardrail, and then insert the component to be installed, such as the cross bar 6 of the guardrail, into the sliding sleeve from the rear end. The sliding sleeve can slide back and forth within a certain range relative to the cross bar. During installation, compress the elastic member to make the sliding sleeve retreat, and then insert the boss into the concave cavity, release the elastic member, and after the external force is lost, the boss will be firmly embedded in the concave cavity under the action of the elastic member, thereby realizing the connection between the two components. When disassembling, just reverse the operation. Due to the presence of the elastic member seat and the elastic member, the cross bar can adaptively adjust the length of extending into the sliding sleeve, the size is easy to control, the precision requirement is low, and the installation is convenient and quick.

[0042] To ensure connection stability, see Figures 1 to 4 The boss 21 includes a limiting portion 211 and a supporting portion 212 distributed front and back. The cross-sectional dimension of the limiting portion 211 is larger than that of the supporting portion 212. The side of the support seat 1 is provided with an installation opening 14 for the limiting portion 211 to enter the concave cavity 13. The rear end of the support seat 1 is provided with a clearance opening 15 for making way for the supporting portion 212 when the limiting portion 211 enters the concave cavity 13. The clearance opening 15 forms a limiting fit with the limiting portion 211. With this design, the boss does not enter the concave cavity along its axial direction, but enters the concave cavity along its radial direction. Since the clearance opening forms a limiting fit with the limiting portion, after installation, the boss cannot escape from the concave cavity along its axial direction from the clearance opening, thereby increasing the connection stability.

[0043] To further ensure installation stability, see Figures 1 to 4 The front end of the boss 21 is provided with a plug post 213. The bottom wall of the cavity 13 is provided with a socket 16. The plug post 213 is inserted into the socket 16. The dimensions of the cavity 13 and the installation opening 14 are such that the limiting portion 211 and the plug post 213 can be inserted simultaneously. During installation, the elastic member is first compressed to retract the sliding sleeve, and the limiting portion and the plug post are extended into the cavity from the installation opening. The elastic member is then released. Under the action of the elastic member, the limiting portion moves toward the bottom of the cavity, and the plug post is inserted into the socket. With this design, the boss cannot radially escape from the cavity from the installation opening due to the mutual interference between the plug post and the socket, thereby achieving two-way limiting and greatly improving the connection stability.

[0044] In order to further ensure the installation stability, the cross section of the limiting portion 211 is consistent with the cross section of the cavity 13. In this design, the limiting portion fits closely with the cavity wall of the cavity, which can reduce shaking and provide greater stability.

[0045] Preferably, see Figures 1 to 4 The cross section of the limiting portion 211 and the cross section of the cavity 13 are square. With this design, the two cannot rotate relative to each other, and the stability is good. More importantly, the boss can be installed in the cavity in any direction by changing 90 degrees or 180 degrees. Figure 3 and Figure 4 As shown, the scope of use is expanded. In this way, the guardrail can be installed in a lying position so that the crossbar presses on the mattress to achieve the effect of pressing the mattress, and can also be installed in a vertical position so that the crossbar is close to the side of the mattress.

[0046] To improve the connection performance, see Figures 1 to 4The support base 1 includes a connecting portion 11 and a cylindrical mounting portion 12. The concave cavity 13 is provided on the connecting portion 11. The insertion hole 16 is connected to the cylindrical mounting portion 12. The insertion column 213 extends into the cylindrical mounting portion 12. With this design, a component to be installed, such as the vertical pole 5 of the guardrail, can be sleeved into the cylindrical mounting portion, making installation more convenient and quick. Moreover, the insertion column can be inserted into the vertical pole 5 to further secure the vertical pole 5. As shown in the figure, a limiting groove 51 is provided on the vertical pole 5, and the insertion column 213 is snapped into the limiting groove 51.

[0047] Preferably, see Figures 1 to 4 A reinforcing rib 17 is connected between the connecting portion 11 and the cylindrical mounting portion 12 to increase the structural strength and stability of the support seat.

[0048] To increase the connection effect, see Figure 1 and Figure 2 The sliding sleeve 2 is provided with one or more limiting structures, including a suspended spring piece 23 formed by a U-shaped groove 22 provided on the sliding sleeve 2, and a buckle 24 provided on the inner side of the spring piece 23. This design allows the spring piece formed by the U-shaped groove to have a certain elasticity, allowing the buckle to be buckled onto the second component to be installed, such as the crossbar 6 of the guardrail. As shown in the figure, the crossbar 6 is provided with a limiting hole 61. When the crossbar 6 enters the sliding sleeve 2, the crossbar 6 squeezes the spring piece 23 and the buckle 24 and bends them outward. When it slides to the limiting hole 61, the spring piece 23 returns to its original position and the buckle 24 enters the limiting hole 61, thereby limiting the crossbar.

[0049] Preferably, the elastic member 4 of the present invention is a spring, which is easy to install and provides a uniform and reliable elastic force.

[0050] Preferably, see Figure 1 and Figure 2 The front end of the elastic member seat 3 is provided with a mounting post 31, and the boss 21 is provided with a mounting hole 214. One end of the elastic member 4 is sleeved on the mounting post 31, and the other end is inserted into the mounting hole 214. This design is not only convenient for installation, but also makes the elastic member less likely to shake and more stable.

[0051] The guardrail connection mechanism of the present invention can be used on any product with guardrails, such as beds. Specifically, the present invention provides a guardrail bed, comprising a bed frame and guardrails. The guardrails are assembled using the guardrail connection mechanism of the present invention, resolving the problems of the prior art. Both the bed frame and guardrails are conventional structures and, for the sake of simplicity, are not shown in the accompanying drawings. The figure only shows a schematic diagram of the guardrail's vertical and horizontal bars connected using the guardrail connection mechanism of the present invention.

[0052] Preferably, see Figure 1 and Figure 2The cross bar 6 of the guardrail is a hollow structure. The cross bar 6 is sleeved outside the elastic member seat 3. The front end of the elastic member seat 3 is provided with a circle of flanges 32 that cooperate with the cross bar 6 in a limiting manner.

[0053] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
