Description

Technical Field

[0001] This utility model relates to the field of infant and toddler protective products technology, and in particular to a connection and locking structure for a bed rail. Background Technology

[0002] Bed rails can be installed on beds to prevent infants and toddlers from falling off while sleeping or playing, ensuring their safety. Traditional bed rails generally have upright posts and a top crossbar. The top crossbar can slide up and down along the upright posts or fold down along with part of the upright posts. When it is necessary to take the infant or toddler out of the bed, the two sides of the top crossbar are unlocked from the upright posts, allowing the top crossbar to descend along the upright posts, or the bed rail is flipped down to the horizontal position of the top crossbar.

[0003] However, traditional bed rails have the following shortcomings: Traditional vertically lifting bed rails typically only have one locking mechanism between the horizontal bar and the vertical bar. Accidentally pressing the unlock button on this mechanism may unlock the entire system, posing a safety hazard. Furthermore, the locking mechanism is relatively complex, inconvenient to operate, and prone to jamming. Foldable bed rails, on the other hand, require unlocking both sides of the foldable section connected to the vertical bar before the rail can be folded outwards, which is time-consuming and laborious.

[0004] Therefore, this utility model was created based on the above-mentioned shortcomings. Utility Model Content

[0005] The purpose of this invention is to overcome the shortcomings of the prior art and provide a simple, double-anti-accidental-touch connection and locking structure for bed rails. This connection and locking structure can prevent jamming, unlock quickly, and is safer and more convenient to use.

[0006] The objective of this utility model is achieved through the following technical solution:

[0007] A bed rail connection and locking structure includes a first connecting seat and a second connecting seat. The first connecting seat has a lock seat, and a first connecting part for connecting the bed rail is fixedly connected to the rear end of the lock seat. Each lock seat has independently controlled latching assemblies on both its left and right sides. Each latching assembly includes a switch latch movably mounted on the lock seat and a push spring located between the switch latch and the lock seat. The switch latch has a pressing end exposed on the lock seat. The second connecting seat has a locking part and a second connecting part fixedly connected thereto. Both sides of the locking part have lock holes adapted to the switch latch. When the first connecting seat and the second connecting seat are aligned, the switch latch is engaged in the lock holes under the action of the push spring to achieve locking. To unlock, the pressing ends of the switch latches on both sides must be pressed simultaneously to disengage them from the lock holes.

[0008] As described above, in the connection and locking structure, the locking part includes two side ears fixed to the left and right sides of the second connection part, and the lock hole is a through hole penetrating the side ears; in the connected state, the lock seat is located between the two side ears.

[0009] As described above, in the connection locking structure, the inner side of the side ear is provided with a guide groove for guiding the switch latch to slide into the lock hole during docking.

[0010] In the connection locking structure described above, the width of the guide groove gradually decreases from the end away from the lock hole to the end closer to the lock hole.

[0011] As described above, in the connection and locking structure, a cover is connected to the lock seat, and an operating hole is provided on the cover; the pressing end of the switch latch slides through the operating hole, and the switch latch is also provided with an anti-disengagement structure, which abuts against the cover in the locked state to prevent the switch latch from disengaging from the operating hole.

[0012] As described above, in the connection and locking structure, the lock seat is provided with a guide post; the switch latch is provided with a clearance hole, the clearance hole is coaxial with the guide post and its diameter is larger than the outer diameter of the guide post; the push spring is sleeved on the guide post and located in the clearance hole.

[0013] As described above, in the connection and locking structure, the cover is detachably connected to the lock seat; the cover is provided with an extension body, and the extension body is provided with a plurality of outwardly extending lugs; the lock seat is provided with a locking hole that matches the lugs, and the lugs engage with the locking hole to fix the cover.

[0014] As described above, in the connection and locking structure, the first connecting part is fixedly connected to the horizontal bar of the bed rail, the second connecting part is fixedly connected to the vertical bar of the bed rail, and the guide groove is located directly below the lock hole.

[0015] As described above, in the connection and locking structure, the first connecting part is fixedly connected to the vertical bar of the bed rail, the second connecting part is fixedly connected to the horizontal bar of the bed rail, and the guide groove is located directly above the lock hole.

[0016] Compared with the prior art, the present invention has the following advantages:

[0017] 1. The connecting and locking structure of this utility model bed rail has independent locking components on both sides. Both sides of the switch lock must be pressed simultaneously to unlock, which has a double anti-accidental touch function. Compared with the single-sided unlocking locking structure, it fundamentally solves the safety hazards and is safer to use.

[0018] 2. The connection and locking structure of the bed rail of this utility model is simple in structure. The guide post and the avoidance hole cooperate to prevent the push spring from deflecting. In addition, the guide groove width gradient design guides the switch lock to be accurately embedded into the lock hole, which effectively solves the jamming problem of the previous locking structure and makes the connection and locking structure of this utility model more reliable.

[0019] 3. The connection and locking structure of this utility model bed rail is easy to maintain; the cover can be removed by pressing the lugs. Attached Figure Description

[0025] The present invention will now be described in further detail with reference to the accompanying drawings and specific embodiments.

[0026] like Figure 1 and Figure 2 As shown, in this utility model, a bed rail connection and locking structure includes a first connecting seat 1 and a second connecting seat 2; the first connecting seat 1 is provided with a lock seat 11, and the rear end of the lock seat 11 is fixedly connected to a first connecting part 12 for connecting the bed rail 3; the left and right sides of the lock seat 11 are provided with independently controlled latching assemblies 13, each latching assembly 13 including a switch latch 131 movably disposed on the lock seat 11 and a push spring 132 disposed between the switch latch 131 and the lock seat 11. The first connecting seat 1 has a pressing end 1311 exposed on the lock seat 11; the second connecting seat 2 is provided with a locking part 21 and a second connecting part 22 fixed thereto, and the left and right sides of the locking part 21 are provided with lock holes 23 adapted to the switch latch 131; when the first connecting seat 1 and the second connecting seat 2 are connected, the switch latch 131 is inserted into the lock hole 23 under the action of the push spring 132 to achieve locking; when unlocking, the pressing ends 1311 of the switch latch 131 on both sides must be pressed at the same time to disengage it from the lock hole 23.

[0027] The bed rail of this utility model has an independent locking structure on both sides with locking components 13. Both locking components 131 on both sides must be pressed simultaneously to unlock it, which has a double anti-accidental touch function. Compared with the locking structure that unlocks on one side, it fundamentally solves the safety hazards and is safer to use.

[0028] like Figure 1-2 As shown, the locking part 21 of this utility model includes two side ears 211 fixed to the left and right sides of the second connecting part 22, and the lock hole 23 is a through hole penetrating the side ears 211; in the connected state, the lock seat 11 is located between the two side ears 211. When the locking structure is locked, the pressing end 1311 on the two side switch latches 131 is embedded in the lock hole 23 and can be exposed on the side ears 211, which makes it easier for the operator to press the pressing end 1311 on the switch latches 131 to unlock.

[0029] Specifically, such as Figure 2 As shown, the inner side of the side ear 211 of this utility model is provided with a guide groove 2111 for guiding the switch latch 131 to slide into the lock hole 23 during docking. The guide groove 2111 guides the switch latch 131 to be embedded into the lock hole 23, preventing jamming during the operation of the locking structure.

[0030] Furthermore, in this embodiment of the invention, the width of the guide groove 2111 gradually decreases from the end furthest from the lock hole 23 to the end closest to the lock hole 23. This allows for more precise guidance of the switch latch 131 into the lock hole 23. In practical applications, to further ensure precise guidance of the switch latch 131 into the lock hole 23, the depth of the guide groove 2111 can also gradually decrease from the end furthest from the lock hole 23 to the end closest to the lock hole 23.

[0031] like Figure 3-4 As shown, the lock base 11 of this utility model is connected to a cover 14, and the cover 14 is provided with an operation hole 141; the pressing end 1311 of the switch latch 131 is slidably inserted into the operation hole 141, and the switch latch 131 is also provided with an anti-disengagement structure 1312. The anti-disengagement structure 1312 abuts against the cover 14 in the locked state to prevent the switch latch 131 from disengaging from the operation hole 141.

[0032] Specifically, the cover 14 is detachably connected to the lock base 11; the cover 14 is provided with an extension 142, and the extension 142 is provided with multiple outwardly extending lugs 143; the lock base 11 is provided with locking holes 112 that match the lugs 143, and the lugs 143 engage with the locking holes 112 to fix the cover 14. Pressing the lugs 143 allows the cover 14 to be removed, making the connection and locking structure of this bed rail more convenient to maintain.

[0033] Furthermore, such as Figure 3-4As shown, the lock base 11 of this utility model is provided with a guide post 111; the switch latch 131 is provided with a clearance hole 133, which is coaxial with the guide post 111 and has a diameter larger than the outer diameter of the guide post 111; the push spring 132 is sleeved on the guide post 111 and located in the clearance hole 133. The cooperation between the guide post 111 and the clearance hole 133 prevents the push spring 132 from deflecting, further solving the jamming problem of previous locking structures, making the connection locking structure of this utility model more reliable.

[0034] like Figure 5 As shown, this utility model relates to an installation embodiment of the connecting and locking structure of the bed rail in a bed rail. In this embodiment, the first connecting part 12 is fixedly connected to the horizontal bar 31 of the bed rail 3, and the second connecting part 22 is fixedly connected to the vertical bar 32 of the bed rail 3. The guide groove 2111 is located directly below the lock hole 23. Thus, when the switch latches 131 on both sides of the first connecting seat 1 are pressed simultaneously, due to the gravity of the horizontal bar 31 and the first connecting seat 1, the switch latches 131 will slide into the guide groove 2111 directly below the lock hole 23 more quickly. This allows the first connecting seat 1 on the horizontal bar 31 to unlock more quickly from the second connecting seat 2 connected to the vertical bar 32, thereby allowing the horizontal bar 31 and the vertical bar 32 on the bed rail 3 to separate more quickly.

[0035] During normal installation, the first connecting part 12 on the first connecting seat 1 is inserted into the inner cavity of the crossbar 31 or sleeved on the outside of the crossbar 31 and fixedly connected by screws; the second connecting part 22 on the second connecting seat 2 is generally provided with an adjustable vertical hole and sleeved on the outside of the vertical bar 32.

[0036] Of course, in actual installation and use, the first connecting part 12 can also be fixedly connected to the vertical bar 32 of the bed rail 3, and the second connecting part 22 can be fixedly connected to the horizontal bar 31 of the bed rail 3, with the guide groove 2111 located directly above the lock hole 23. In this way, when the switch latches 131 on both sides of the first connecting seat 1 are pressed at the same time, due to the gravity of the vertical bar 32 and the second connecting seat 2, the switch latches 131 will slide into the guide groove 2111 directly above the lock hole 23 more quickly, so that the second connecting seat 2 on the vertical bar 32 can unlock from the first connecting seat 1 connected to the horizontal bar 31 more quickly, thereby allowing the horizontal bar 31 and the vertical bar 32 on the bed rail 3 to separate more quickly.
