A lifting and adjusting structure for bed guardrail

Abstract

The present invention discloses a bed guardrail lifting and adjustment structure, specifically relating to the technical field of bed guardrails. The structure comprises a vertical tube and a sliding sleeve slidably disposed on the outer side of the vertical tube. A through hole is formed in the sidewall of the upper end of the vertical tube. A bottom plug is mounted inside the vertical tube. A button corresponding to the through hole is connected to the bottom plug via an elastic component. One side of the button has an inclined surface (1). The sliding sleeve has a slot corresponding to the button. A second inclined surface is disposed on the inner side of the upper end of the sliding sleeve. When the sliding sleeve slides upward, the second inclined surface pushes the first inclined surface, causing the button to move inward of the vertical tube. When the sliding sleeve is in place, the button passes through the through hole and the slot, thereby locking the sliding sleeve on the vertical tube. Due to the provision of the first and second inclined surfaces, when the sliding sleeve needs to be moved to its original position, the sliding sleeve only needs to be slid upward. The second inclined surface can interfere with the first inclined surface, forcing the button to move inward of the vertical tube. That is, when adjusting the sliding sleeve to its original position, there is no need to press the button, making operation simple and convenient.

Description

Technical Field

[0001] The present invention relates to the technical field of bed guardrails, and more particularly to a lifting and adjusting structure of a bed guardrail. Background Art

[0002] There are various styles of cribs on the market, including solid wood cribs, bamboo cribs, rattan cribs, metal frame cribs, etc., and the functions are also varied, such as foldable portable cribs, adjustable cribs, smart cribs with controls, etc. When purchasing, people usually give priority to their safety and convenience.

[0003] In order to facilitate the placement and removal of babies, cribs are currently usually designed with a lifting and adjusting structure. Generally, a sliding sleeve is placed on the vertical riser of the crib, and two buttons are provided. A separate spring or shrapnel is provided between the two buttons for reset. The sliding sleeve is locked on the riser by pressing the button. When adjusting the height, the height of the sliding sleeve can be adjusted by pressing the button toward the middle.

[0004] However, the above structure has operational difficulties during adjustment. For example, in order to put a baby into the crib, the operator needs to first lower the height of the slide sleeve, and then adjust the slide sleeve to its original position after putting the baby in the crib. However, during the adjustment process to the original position, the operator needs to press two buttons before the slide sleeve can slide into place and be stuck by the buttons. Summary of the Invention

[0005] In order to overcome the above-mentioned defects of the prior art, the present invention provides a lifting and adjusting structure for a bed guardrail. When adjusting the sliding sleeve to the original position, there is no need to press a button. The sliding sleeve can be directly adjusted to the position and locked by the button.

[0006] To achieve the above object, the present invention provides the following technical solutions:

[0007] A bed guardrail lifting and adjusting structure includes a vertical tube and a sliding sleeve slidably arranged on the outside of the vertical tube. A through hole is formed in the side wall of the upper end of the vertical tube. A bottom plug is installed inside the vertical tube. A button corresponding to the through hole is connected to the bottom plug via an elastic component. One side of the button has an inclined surface 1. The sliding sleeve has a slot corresponding to the button. The inner side of the upper end of the sliding sleeve is provided with an inclined surface 2.

[0008] When the sliding sleeve slides upward, the second inclined surface pushes the first inclined surface to move the button toward the inside of the vertical pipe. When the sliding sleeve moves into place, the button passes through the through hole and the slot to clamp the sliding sleeve on the vertical pipe.

[0009] Preferably, there are two through holes, two buttons and two inclined surfaces 2, and the two through holes, the two buttons and the two inclined surfaces 2 are arranged relative to each other.

[0010] Preferably, the bottom end of the button can bear against the inner wall of the slot.

[0011] Preferably, the elastic component is an elastic plastic part, and the bottom plug, the elastic plastic part and the button are integrally formed.

[0012] Preferably, the slot is a circular hole.

[0013] Preferably, it also includes a pipe plug installed at the upper end of the vertical pipe, with clamping holes on both sides of the bottom end of the pipe plug, and elastic fixing buckles corresponding to the clamping holes on both sides of the bottom plug, and the elastic fixing buckles engage with the clamping holes to enable the bottom plug to be installed at the bottom end of the pipe plug.

[0014] Preferably, an undercut is provided on one side of the pipe plug, and a bayonet is provided on the upper end of the vertical pipe, and the undercut is engaged with the bayonet so that the pipe plug is installed on the vertical pipe.

[0015] Preferably, two elastic fixing buckles are provided on both sides of the bottom plug.

[0016] Preferably, the bottom of the pipe plug is in an inverted U shape, and the button is arranged on the inner side of the inverted U shape.

[0017] The technical effects and advantages of the present invention are as follows:

[0018] 1. Through the setting of inclined surface 1 and inclined surface 2, when the sliding sleeve needs to be moved to its original position, it only needs to slide the sliding sleeve upward, and inclined surface 2 can conflict with inclined surface 1, which can force the button to move toward the inside of the riser. That is, when adjusting the sliding sleeve to its original position, there is no need to press the button, which is simple and convenient to operate.

[0019] 2. The lifting and adjusting structure has a small number of parts and components, no small parts, easy installation and operation, and low manufacturing cost. BRIEF DESCRIPTION OF THE DRAWINGS

[0027] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0028] Example

[0029] like Figures 1 to 5 As shown, this embodiment provides a bed guardrail lifting and adjusting structure, including a vertical tube 1 and a sliding sleeve 3 slidably arranged on the outside of the vertical tube 1. A through hole 11 is formed in the side wall of the upper end of the vertical tube 1. A bottom plug 2 is installed inside the vertical tube 1. A button 22 corresponding to the through hole 11 is connected to the bottom plug 2 via an elastic component 21. One side of the button 22 has an inclined surface 1 23. The sliding sleeve 3 has a slot 31 corresponding to the button 22. The inner side of the upper end of the sliding sleeve 3 is provided with an inclined surface 22.

[0030] When the sleeve 3 slides upward, the second inclined surface 32 pushes the first inclined surface 23 to move the button 22 toward the inside of the standpipe 1. When the sleeve 3 moves into place, the button 22 passes through the through hole 11 and the slot 31 to lock the sleeve 3 on the standpipe 1.

[0031] It should be noted that the button 22 can be positioned upright (i.e., vertically, facing the through-hole 11 and the slot 31), with the inclined surface 1 23 positioned on the front side of the button 22. The button 22 can also be tilted, where the front side is tilted, forming the inclined surface 1 23. In short, it is sufficient to ensure that the inclined surface 1 23 on the front side of the button 22 has an appropriate tilt angle.

[0032] By setting the above-mentioned inclined surface 1 23 and inclined surface 2 32, the sliding sleeve 3 can be moved downward after pressing the button 22 to release the lock of the sliding sleeve 3. When the sliding sleeve 3 needs to be moved to its original position, it only needs to slide the sliding sleeve 3 upward. The inclined surface 2 32 conflicts with the inclined surface 1 23, forcing the button 22 to move toward the inside of the standpipe 1. When the sliding sleeve 3 moves upward until the slot 31 is aligned with the button 22, the button 22 pops out and locks the movement of the sliding sleeve 3. That is, when adjusting the sliding sleeve 3 to its original position, there is no need to press the button 22, which makes the operation simple and convenient.

[0033] In this embodiment, if Figure 3 and Figure 5 As shown, two through holes 11, two buttons 22, and two second inclined surfaces 32 are each provided, and are arranged opposite to each other between the two through holes 11, the two buttons 22, and the two second inclined surfaces 32. By providing two buttons 22, locking of the sliding sleeve 3 is more stable, and during operation, both buttons 22 can be pressed simultaneously without causing any operational difficulties.

[0034] In this embodiment, if Figure 3 and Figure 5 As shown, the bottom end of the button 22 can bear against the inner wall of the slot 31. In other words, the inclination of the inclined surface 1 23 must be appropriately maintained. After the sleeve 3 is moved into position, i.e., the button 22 enters the slot 31, the bottom end of the button 22 must be located within the slot 31 so as to bear against the inner wall of the slot 31. This ensures that, after the sleeve 3 is moved into position, the sleeve 3 cannot move upward without pressing the button 22. If the bottom end of the button 22 is not located within the slot 31, the sleeve 3 can still slide upward without pressing the button 22, which reduces safety and may cause the baby to accidentally lift it.

[0035] In this embodiment, if Figure 3-Figure 5 As shown, the elastic component 21 is an elastic plastic part, and the bottom plug 2, the elastic plastic part, and the button 22 are integrally formed. Of course, the elastic component 21 can also be a spring or a shrapnel that can reset the button 22.

[0036] In this embodiment, if Figure 1-Figure 2 As shown, the slot 31 is a circular hole, which is beautiful and easy to operate the button 22.

[0037] In this embodiment, if Figure 2-Figure 5 As shown, to facilitate installation of the bottom plug 2, a pipe plug 4 is provided, mounted on the upper end of the riser 1. The bottom end of the pipe plug 4 is provided with locking holes 41 on both sides. Both sides of the bottom plug 2 have elastic fixing buckles 24 corresponding to the locking holes 41. The elastic fixing buckles 24 engage with the locking holes 41, thereby securing the bottom plug 2 to the bottom end of the pipe plug 4. The bottom plug 2 is inserted from the bottom end of the pipe plug 4, allowing the elastic fixing buckles 24 to engage with the locking holes 41. The bottom plug 2 is then inserted from the upper end of the riser 1.

[0038] Furthermore, a buckle 42 is provided on one side of the pipe plug 4, and a bayonet 12 is provided on the upper end of the riser 1. The buckle 42 engages with the bayonet 12 to thereby secure the pipe plug 4 to the riser 1. This ensures that the pipe plug 4, the bottom plug 2, and the riser 1 are securely mounted.

[0039] Furthermore, two elastic fixing buckles 24 are provided on both sides of the bottom plug 2, making the installation more stable.

[0040] Furthermore, the bottom of the pipe plug 4 is in an inverted U shape, and the button 22 is arranged inside the inverted U shape, making the structure more compact and, at the same time, enabling the button 22 to be as close to the top as possible to prevent the upper end of the riser 1 from extending too long.

[0041] Installation method: Figure 2-Figure 5 As shown, first, the bottom plug 2 is inserted into the bottom end of the pipe plug 4, so that the elastic fixing buckle 24 is engaged with the locking hole 41, and then the sliding sleeve 3 is put on the vertical pipe 1. Next, the bottom plug 2 is facing downward, and the pipe plug 4 and the bottom plug 2 are inserted into the interior of the vertical pipe 1 together, so that the undercut 42 is engaged with the bayonet 12, and then the sliding sleeve 3 is moved upward to lock the sliding sleeve 3 with the button 22. The number of parts is small, there are no small parts, the installation is convenient, and the manufacturing cost is low.

[0042] Working principle: refer to Figure 1 The baby bed guardrail in the case shown has two sets of lifting and adjusting structures. A connecting piece 5 is rotatably installed on the sliding sleeve 3 of each set of lifting and adjusting structures. The connecting piece 5 is detachable, and an upper horizontal tube 51 is inserted between the two connecting pieces 5. When the height of the upper horizontal tube 51 needs to be lowered, the buttons 22 on both sides are pressed down at the same time to unlock the sliding sleeve 3 and slide down. During the sliding movement of the sliding sleeve 3, the connecting piece 5 rotates relative to the sliding sleeve 3 to realize unilateral lifting of the bed guardrail; when the sliding sleeve 3 slides from bottom to top until it contacts the button 22, the second inclined surface 32 conflicts with the first inclined surface 23. During the process of the sliding sleeve 3 continuing to move upward, the button 22 is forced to move toward the inside of the vertical tube 1 under the action of the second inclined surface 32. When the sliding sleeve 3 moves upward until the slot 31 is aligned with the button 22, the button 22 pops out and locks the movement of the sliding sleeve 3. The operation is simple and convenient.

[0043] Finally, a few points should be explained: First, in the description of this application, it should be noted that, unless otherwise specified or limited, the terms "mounted," "connected," and "connected" should be understood broadly, and may refer to mechanical or electrical connections, internal communication between two components, or direct connection.
