Description

Technical Field

[0001] The utility model belongs to the technical field of guardrail folding joints, in particular to a folding joint structure of a children's bedside guardrail. Background Art

[0002] The ideal height for children's bedside guardrails is 50cm above the mattress. If they are too low, there's a risk that children will climb over them and fall once they're able to hold onto them. If they are too high, it's very difficult for parents to lift or lower their babies.

[0003] The folding joint is particularly important for children's bedside guardrails. As the supporting component that keeps the bedside guardrail upright, the folding joint directly affects the safety of the children's bedside guardrail. Currently, children's bedside guardrails have the following problems:

[0004] Referring to the patent document with application number 201921044336.2, it includes a first connecting part, a first rod, a second connecting part, and a second rod. The first rod and the second rod are connected and fixed by the first connecting part and the second connecting part that are staggered and docked with each other. This structure is a traditional commonly used structure. When the middle bolt becomes loose, the connection between the first connecting part and the second connecting part loses stability and is very prone to cracking and breaking.

[0005] Traditional folding joints use a single lock and a single unlocking part; the single lock has a small limiting ability on the folding joint, and after being subjected to a certain pressure, the bracket will automatically lose its limiting ability. At the same time, the single unlocking part has the problem of accidental unlocking, which poses a certain safety hazard. Utility Model Content

DETAILED DESCRIPTION

[0022] To make the objectives, technical solutions, and advantages of the present invention more clearly apparent, the present invention is described below using specific embodiments illustrated in the accompanying drawings. However, it should be understood that these descriptions are merely illustrative and are not intended to limit the scope of the present invention. Furthermore, descriptions of known structures and technologies are omitted in the following description to avoid unnecessary confusion regarding the concepts of the present invention.

[0023] It should also be noted here that, in order to avoid obscuring the present invention due to unnecessary details, only structures and / or processing steps closely related to the solution according to the present invention are shown in the accompanying drawings, while other details that are not closely related to the present invention are omitted.

[0024] See Figure 1-Figure 4As shown, this specific embodiment adopts the following technical solution: it includes an upper seat 1 and a lower seat 2, and the lower seat 2 is composed of a lower seat assembly 1 21 and a lower seat assembly 2 22; the upper seat 1 is movably connected to the front end reserved groove of the lower seat 2, and a rivet 10 is inserted into the middle reserved hole of the upper seat 1 and the lower seat 2, and the upper seat 1 and the lower seat 2 are movably connected together by the limiting effect of the rivet 10; wherein, a through-type embedded groove 3 is provided inside the upper seat 1, and a pair of positioning blocks 5 are movably embedded at the two ends of the embedded groove 3. The two positioning blocks 5 are connected by a return spring 4. The positioning blocks 5 engage with the limiting slots 6 on the inner surfaces of the lower assembly 1 21 and the lower assembly 2 22 to lock the upper seat 1 and the lower seat 2. The outer surfaces of the front connecting plates of the lower assembly 1 21 and the lower assembly 2 22 are provided with a locking slot 7. A button 9 is movably engaged with a spring 8 in the locking slot 7. Pressing the button 9 causes the positioning block 5 to retract and separate from the limiting slot 6, thereby unlocking the upper seat 1 and the lower seat 2. The surface of the positioning block 5 is provided with a boss, which is kept plugged into the limiting slot 6 to achieve the purpose of limiting.

[0025] Meanwhile, lower seat assembly 1 21 and lower seat assembly 2 22 maintain identical structures, each consisting of a rear connecting arm 23 and a front connecting disc 24. The two sets of rear connecting arms 23 snap together to form a flat tube 25, into which the lower support assembly is inserted. The space between the two front connecting discs 24 forms an upper seat insertion slot 26. The width of the upper seat insertion slot 26 matches the width of the upper seat 1, ensuring a perfect insertion of the two. The rivet 10 inserted between them secures them. If the rivet 10 becomes damaged or loosened, the button 9 prevents the rivet 10 from completely disengaging from the insertion slot, thus preventing the upper seat 1 from falling apart.

[0026] In addition, the inner side of the front connecting disc 24 is provided with a circle of supporting ribs 27, one side of which is connected to an integral retaining groove 6, which aligns with the flat tube 25. The supporting ribs 27 support the positioning block 5, effectively preventing it from disengaging from the slot 3 during movement. The outer side of the front connecting disc 24 is provided with an inner recessed slot 28, with several retaining grooves 29 arranged along its edge. The outer edge of the button 9 is provided with a circle of barbed posts 91, which engage with the retaining grooves 29. A spring 8 is provided between the button 9 and the inner recessed slots 28 to realize a press-to-reset mechanism for the button 9. One set of retaining grooves 29 aligns with the retaining groove 6, allowing the barbed posts 91 inserted into the retaining grooves 29 to eject the positioning block 5, which is engaged in the retaining groove 6, thereby unlocking the button 9.

[0027] After adopting the above structure, the beneficial effects of the utility model are: it adopts a two-way locking structure, which can improve the structural stability of the folding joint after locking, and avoid safety problems caused by unstuck under extreme pressure. In addition, it adopts a double-sided press unlocking structure to further improve the safety of the folding joint and avoid the problem of misoperation caused by unilateral squeezing. Example

The lower end of the adjustable flat tube bracket B is connected to the bottom bracket C. A protective net D is connected between the cross beams of the U-shaped support frame A and the H-shaped adjustable flat tube bracket B. The bottom bracket C is pressed against the lower end of the mattress. In addition, the height of the specific adjustable flat tube bracket B is adjusted to keep the folding joint flush with the upper edge of the mattress. In addition, the folding joint remains in an outward folded state.
