Description

Technical Field

[0001] This utility model belongs to the field of children's beds, specifically relating to a convenient swing locking structure and a children's bed. Background Technology

[0002] As a common infant care product, children's beds are widely used in homes, childcare facilities, and medical institutions, mainly to soothe infants, help them fall asleep, or provide gentle passive movement stimulation.

[0003] Currently, children's beds on the market are mainly divided into fixed and swinging types. Fixed children's beds have a relatively simple structure and their use is often limited. In swinging children's beds, most designs achieve the swinging motion by having an arc-shaped bottom, or by suspending the bed from a support frame using flexible ropes, springs, or rigid linkages, relying on gravity and inertia to complete the swing. Although the above structures are effective in achieving basic swinging functions, they still reveal many shortcomings in actual use. For example, when parents want to temporarily fix the rocker in a static state (such as during feeding, diaper changing, preventing the baby from shaking when turning over, or avoiding accidental swinging during movement), they often have to rely on external objects (such as towels or wooden blocks) to prop up the base, or forcibly press down on the bed with their hands. This operation is extremely inconvenient and carries the risk of slipping. This "unlocked" design not only affects the user experience, but also may cause the rocker to swing uncontrollably in sudden situations (such as a baby kicking violently, a pet bumping into it, or uneven ground), leading to tipping over or pinching accidents, seriously affecting the safety of children's beds. Utility Model Content

[0004] The purpose of this invention is to address the aforementioned problems in the existing technology by proposing a simple, safe, and convenient swing locking structure for a children's bed that can lock the bed in the desired position.

[0005] The objective of this utility model can be achieved by addressing the following technical problem: proposing a convenient swing locking structure for unlocking and locking the bed, including:

[0006] Support frame, used to assemble and support the bed frame;

[0007] A swing assembly having a swing block that can switch between an initial position and a swing position of the support frame, the swing block being movably connected to the bed body to drive the bed body to swing relative to the support frame;

[0008] A locking assembly is provided within the support frame. The locking assembly includes an unlocking block and a stop pin. When the unlocking block moves, it can release the stop pin so that the stop pin can restrict the swing block to the initial position or the swing position.

[0009] When the swing block is in the initial position, the stop pin is inserted into the swing block, and the swing block is perpendicular to the bottom wall of the bed and aligned with the support frame.

[0010] When the swing block is in the swing position, the stop pin extends outside the support frame and abuts against the side wall of the swing block to restrict the swing block to an inclined posture.

[0011] In the aforementioned convenient swing locking structure, the locking assembly further includes a movable block, a vertical plate with a horizontal guide groove is formed on the support frame, the movable block is movably disposed in the horizontal guide groove, the stop pin is detachably connected to the movable block, and the unlocking block is movably inserted into the movable block.

[0012] In the aforementioned convenient swing locking structure, a mounting groove is formed inside the moving block, and an elastic element is connected between the inner wall of the mounting groove and the inner wall of the horizontal guide groove.

[0013] In the above-mentioned convenient swing locking structure, the unlocking block includes an unlocking button and a locking block. The unlocking button is movably disposed on the outer wall of the upright plate and connected to the locking block. A connecting hole is provided in the locking block, and a return spring is connected between the bottom wall of the connecting hole and the upright plate so that the locking block can be inserted into the moving block.

[0014] In the aforementioned convenient swing locking structure, a limiting groove is formed on the outer wall of the upright plate, and a limiting block is formed on the unlocking button, with the limiting block being movably engaged in the limiting groove.

[0015] In the aforementioned convenient swing locking structure, a locking hole is formed on the outer wall of the moving block, and a locking post is formed at the top of the locking block, with the locking post being movably inserted into the locking hole.

[0016] In the aforementioned convenient swing locking structure, the swing block has a first connecting end and a second connecting end, wherein:

[0017] The support frame is provided with a horizontal plate connected to the vertical plate. The first connecting end is pivotally connected to the horizontal plate through a first connecting pin, so that the swing block can rotate relative to the support frame around the first connecting pin.

[0018] The side wall of the bed is formed with a fixed support leg, and a second connecting pin is connected to the fixed support leg. An extension is formed on the side of the second connecting end away from the upright plate, and the extension and the second connecting end are connected to the second connecting pin.

[0019] In the above-mentioned convenient swing locking structure, a guide block is also formed at the first connecting end, and an arc-shaped guide groove is formed in the upright plate, with the guide block movably disposed in the arc-shaped guide groove.

[0020] In the aforementioned convenient swing locking structure, the swing assembly further includes a bearing, which is installed on both the first connecting pin and the second connecting pin, and the outer wall of the bearing is interference-fitted with the inner wall of the first / second connecting end.

[0021] The technical solution adopted by this utility model to solve its technical problem is to also propose a children's bed, including one of the above-mentioned convenient swing locking structures.

[0022] Compared with the prior art, the present invention has the following beneficial effects:

[0023] (1) The present invention provides a convenient swing locking structure and a children's bed. Through the coordinated cooperation of the swing block and the stop pin, the bed can quickly switch between the initial position and the swing position, and can also complete the reliable and stable locking function of the bed. No complicated tools are required, which ensures the safety of children when using the bed, and the bed can maintain absolute stability when the caregiver is taking care of the child.

[0024] (2) By utilizing the cooperation between the guide block and the arc-shaped guide groove, the swing block is constrained by the trajectory of the arc-shaped groove during rotation, ensuring that its swing angle is precisely controllable, avoiding excessive swing or jamming, and improving the smoothness of the swing action and the accuracy of repeated positioning.

[0025] (3) The unlock button can only slide along the direction of the limit groove, which effectively prevents it from rotating or shifting during use, ensuring the linearity and reliability of the unlocking action. At the same time, the limit structure can also limit the unlocking stroke, avoid excessive pressing and damage to internal parts, and extend service life. Attached Figure Description

[0035] The following are specific embodiments of the present invention, which are described in conjunction with the accompanying drawings to further illustrate the technical solutions of the present invention. However, the present invention is not limited to these embodiments.

[0036] It should be noted that all directional indications (such as up, down, left, right, front, back, etc.) in the embodiments of the present invention are only used to explain the relative positional relationship and movement of each component in a certain specific posture (as shown in the figure). If the specific posture changes, the directional indication will also change accordingly.

[0037] like Figure 1 As shown, this solution mainly describes a convenient swing locking structure for use in children's beds. However, this convenient swing locking structure is not limited to use in children's beds, but can also be applied to rocking chair structures in daily life.

[0038] like Figures 1 to 5 As shown, a convenient swing locking structure is used to unlock and lock the bed 1, including a support frame 2, a swing assembly 3 and a locking assembly 4.

[0039] Specifically, in this embodiment, the support frame 2 is used to assemble and support the bed body 1; the swing assembly 3 has a swing block 30 that can switch between the initial position and the swing position of the support frame 2. The swing block 30 is movably connected to the bed body 1 to drive the bed body 1 to swing relative to the support frame 2; the locking assembly 4 is disposed in the support frame 2. The locking assembly 4 includes an unlocking block 40 and a stop pin 41. When the unlocking block 40 moves, it can release the stop pin 41 so that the stop pin 41 can restrict the swing block 30 to the initial position or the swing position; when the swing block 30 is in the initial position, the stop pin 41 is inserted into the swing block 30, and the swing block 30 is perpendicular to the bottom wall of the bed body 1 and aligned with the support frame 2; when the swing block 30 is in the swing position, the stop pin 41 extends out of the support frame 2 and abuts against the side wall of the swing block 30 to restrict the swing block 30 to an inclined posture.

[0040] When the swing block 30 is in the position as Figure 1 In the initial position shown, the swing block 30 is vertically aligned with the support frame 2, and the stop pin 41 is inserted into the swing block 30 at this time (see reference). Figure 2 The structure shown achieves rigid locking. It's worth noting that at this point, the bed 1 is in its lowest position relative to the support frame 2. When the position and height of the bed 1 need to be adjusted, the user manually pushes the unlocking block 40 along... Figure 2 Moving vertically downwards, the stop pin 41 can disengage from the swing block 30 after unlocking. With the constraint on the swing block 30 released, the user can easily push the bed 1, causing the swing block 30 to rotate relative to the support frame 2 from its initial position to the swing position around its hinge point. This allows the entire bed 1 to perform an arc-shaped horizontal lifting operation relative to the support frame 2 until the bed 1 reaches a comfortable position. At this point, the swing block 30 also reaches the preset swing position (i.e., the swing block 30 is in an inclined posture). Under the force of the locking component 4, the stop pin 41 automatically extends out of the support frame 2. With the unlocking block 40 locking the stop pin 41 again, the side wall of the inclined swing block 30 abuts against the stop pin 41, forming a rigid block and preventing the swing block 30 from rotating back to its original position. Figure 1 The bed 1 is reliably locked at the desired height position by the indicated position. Therefore, this embodiment enables rapid switching between the initial position and the swing position of the bed 1. Furthermore, the stop pin 41 automatically engages or abuts against the swing block 30 based on its position, effectively limiting the posture of the swing block 30 and preventing accidental shaking or tipping of the bed 1 during use. This structure simplifies the complex operation of traditional locking mechanisms, improves user convenience and safety, and is particularly suitable for scenarios such as children's beds that require frequent adjustments to position and height.

[0041] The locking assembly 4 also includes a movable block 42. A vertical plate 20 with a horizontal guide groove 200 is formed on the support frame 2. The movable block 42 is movably disposed in the horizontal guide groove 200. The stop pin 41 is detachably connected to the movable block 42. The unlocking block 40 is movably inserted into the movable block 42.

[0042] like Figure 2 As shown, this embodiment utilizes a horizontal guide groove 200 to ensure that the stop pin 41 can slide stably along the horizontal direction with the moving block 42, thereby accurately completing the locking function of the swing block 30. Specifically, as the user pulls the unlocking block 40 along the horizontal direction... Figure 2 When the moving block 42 moves downward and disengages from the moving block 42, the moving block 42 can drive the stop pin 41 along... Figure 2 Move to the right to change the position and height of the bed 1 by swinging the swing block 30. When adjusted to the desired position, the moving block 42 pushes the stop pin 41 out of the support frame 2. With the unlocking block 40 inserted into the moving block 42, the swing block 30 can be restricted to the initial position or swing position. During this process, the horizontal guide groove 200 effectively improves the guiding accuracy of the stop pin 41, avoids the skew, jamming or shaking problems that may occur in the traditional structure, and ensures that the stop pin 41 always moves in and out along the predetermined trajectory, improving the locking reliability and operation smoothness.

[0043] An installation groove 420 is formed inside the movable block 42, and an elastic element 420a is connected between the inner wall of the installation groove 420 and the inner wall of the horizontal guide groove 200.

[0044] Furthermore, such as Figure 2 As shown, when the unlocking block 40 disengages from the moving block 42, the moving block 42 can then rely on the elastic restoring force of the elastic element 420a to move along... Figure 2 Move horizontally to the right until the stop pin 41 disengages from the swing block 30. The bed 1 can then rotate relative to the support frame 2 to the desired height. After the operation is completed, the user squeezes the moving block 42, causing the elastic element 420a to gradually compress. As the stop pin 41 is inserted into or abuts against the swing block 30, the unlocking block 40 can move along... Figure 2 It moves vertically upward and is inserted into the movable block 42, restricting the movement of the movable block 42 together with the stop pin 41 along the opening direction of the horizontal guide groove 200 (i.e., along the direction of the opening). Figure 2 (Moves horizontally) to achieve automatic locking, improving the user experience and enhancing the reliability of locking.

[0045] The unlocking block 40 includes an unlocking button 400 and a locking block 401. The unlocking button 400 is movably disposed on the outer wall of the upright plate 20 and connected to the locking block 401. A connecting hole 401a is provided in the locking block 401. A return spring 201 is connected between the bottom wall of the connecting hole 401a and the upright plate 20 so that the locking block 401 can be inserted into the moving block 42.

[0046] like Figure 2 and Figure 3 As shown, during the unlocking process, the user pulls the unlock button 400 along... Figure 2 The vertical downward movement causes the locking block 401 to disengage from the moving block 42. At this point, the elastic restoring force of the elastic element 420a on the moving block 42 can drive the stop pin 41 along... Figure 2 The horizontal movement to the right disengages the swing block 30. During the unlocking process, the downward movement of the unlock button 400 will inevitably compress the return spring 201, allowing the subsequent moving block 42 to push the stop pin 41 out of the upright plate 20. The return spring 201 then drives the locking block 401 to insert into the moving block 42, completing the automatic locking function. It is worth noting that in this embodiment, the unlock block 40 adopts a separate structure of the unlock button 400 and the locking block 401. The unlock button 400 is exposed on the upright plate 20 for easy user operation, while the locking block 401, relying on the return spring 201, can maintain its inserted position into the moving block 42 without external force, ensuring normal and stable locking. This structure is intuitive to operate, provides clear feedback, and the return spring 201 ensures the stability of the locking state, preventing accidental triggering.

[0047] A limiting groove 202 is provided on the outer wall of the upright plate 20, and a limiting block 400a is formed on the unlock button 400. The limiting block 400a is movably engaged in the limiting groove 202.

[0048] like Figure 4 As shown, during the unlocking action of the unlocking button 400 moving down, the movement of the limiting block 400a within the limiting groove 202 ensures that the unlocking button 400 can only slide along the direction of the limiting groove 202, effectively preventing it from rotating or shifting during use, and ensuring the linearity and reliability of the unlocking action. At the same time, this limiting structure can also limit the unlocking stroke, avoid excessive pressing and damage to internal parts, extend service life, and also prevent the automatic reset locking stroke from being too long and affecting the user's normal use.

[0049] The outer wall of the movable block 42 has a locking hole 420b, and the top of the locking block 401 has a locking pin 401b, which is movably inserted into the locking hole 420b.

[0050] like Figure 2 and Figure 3 As shown, after the moving block 42 drives the stop pin 41 to lock the position of the swing block 30, the locking block 401 can be pushed by the force of the return spring 201 to insert the locking pin 401b into the locking hole 420b, ensuring that the stop pin 41 will not move with the moving block 42. Figure 2The horizontal movement enables precise positioning and secure locking (preventing the moving block 42 from rotating or shifting), preventing loosening under vibration or stress, and further enhancing the stability and safety of the locking state.

[0051] The swing block 30 has a first connecting end 300 and a second connecting end 301, wherein: the support frame 2 is provided with a horizontal plate 21 connected to the upright plate 20, the first connecting end 300 is pivotally connected to the horizontal plate 21 through a first connecting pin 302, so that the swing block 30 can rotate relative to the support frame 2 around the first connecting pin 302; a fixed support leg 10 is formed on the side wall of the bed body 1, and a second connecting pin 303 is connected to the fixed support leg 10; an extension 301a is formed on the side of the second connecting end 301 away from the upright plate 20, and the extension 301a and the second connecting end 301 are connected to the second connecting pin 303.

[0052] like Figure 2 As shown, when the stop pin 41 releases its constraint on the swing block 30, the first connecting end 300 on the swing block 30 can rotate relative to the cross plate 21 around the axis of the first connecting pin 302. At the same time, due to the movable connection between the second connecting end 301 and the second connecting pin 303, the second connecting end 301 rotates synchronously relative to the fixed support leg 10 when the first connecting end 300 swings (i.e., the two are in a movable hinge). Thus, by utilizing the formed double-hinged linkage structure, the bed 1 can swing smoothly around the two fulcrums (the bed 1 always moves in an arc in a horizontal posture). This design not only ensures the smoothness of the swing process but also improves the rigidity and load-bearing capacity of the overall structure. Preferably, in this embodiment, the extension 301a significantly improves the torsional and shear resistance at the second connecting pin 303, avoiding pin wear or breakage caused by unilateral force and extending the service life of the component. It should be noted that in this embodiment, the first connecting pin 302 is inserted into the upright plate 20 and can be locked and fixed by a locking pin; the second connecting pin 303 can be connected to the fixed support leg 10 by a threaded connection. The connection method and principle are the same as those in the prior art, and will not be described in detail here.

[0053] A guide block 300a is also formed at the first connecting end 300, and an arc-shaped guide groove 203 is formed in the vertical plate 20. The guide block 300a is movably disposed in the arc-shaped guide groove 203.

[0054] like Figure 5 As shown, during the rotation of the first connecting end 300 relative to the upright plate 20, the swing block 30 is always constrained by the trajectory of the arc groove, ensuring that its swing angle is precisely controllable and avoiding excessive swing or jamming. This guide structure improves the smoothness of the swing action and the accuracy of repeated positioning, and is especially suitable for children's bed application scenarios with high requirements for posture adjustment accuracy.

[0055] The oscillating assembly 3 also includes a bearing 31, such as Figure 2 As shown, in this embodiment, bearings 31 are installed on both the first connecting pin 302 and the second connecting pin 303. The outer wall of the bearing 31 is interference-fitted with the inner wall of the first / second connecting end 301. The design of the bearing 31 can significantly reduce the frictional resistance during the swinging process, making the bed 1 swing more smoothly and easily. At the same time, the bearing 31 structure can also effectively absorb vibration, reduce wear, improve the durability and quietness of the swinging assembly 3, and enhance the user experience.

[0056] It should be noted that the elastic element 420a in this embodiment can be replaced by other elastic devices such as compression springs or return springs 201. In addition, in this embodiment, cover plates 22 are detachably connected to both the swing block 30 and the upright plate 20 (using screws, bolts, or snap-fit ​​structures). The cover plates 22 can prevent dust and impurities from entering the internal parts, which helps to extend the service life of the structure and also facilitates subsequent disassembly, assembly, and maintenance.
