Technical Field

[0001] This utility model relates to the field of baby crib technology, specifically a baby crib that can be quickly raised and lowered for adjustment. Background Technology

[0002] A crib is a sleep device specially designed for infants and toddlers. It not only provides a safe and comfortable sleep environment, but also helps to cultivate a baby's independent sleep habits.

[0003] To fit into home beds, existing cribs typically have one side adjustable for height. To align with the home bed, this height adjustment is achieved using an end spring post. The adjustment is done by pressing the spring post, requiring both sides to be raised and lowered sequentially, which is time-consuming, laborious, and impractical. Therefore, a crib that allows for convenient, quick, and simultaneous raising and lowering is needed to improve usability. Utility Model Content

[0004] The purpose of this utility model is to provide a baby crib that can be quickly raised and lowered to solve the problem mentioned in the background art. In order to fit with home beds, existing baby cribs generally have one side that is adjustable in height to make it level with the home bed. However, the height adjustment of one side of the baby crib is connected by an end spring column. The raising and lowering is completed by pressing the spring column. The raising and lowering process needs to be carried out step by step on both sides, which is time-consuming, laborious and not suitable for all situations.

[0005] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution:

[0006] This utility model is a baby crib that can be quickly raised and lowered, comprising:

[0007] A frame structure, comprising mounting blocks, mounting frames, and lower sleeves, wherein a set of mounting blocks are symmetrically arranged, and a mounting frame is fixedly connected to the center of the inner side of the mounting blocks, and a lower sleeve is fixed to the upper corner of the mounting frame.

[0008] An adjustable lifting structure includes a guide frame, an adjusting crossbar, a sleeve, a torsion spring, a connecting block, an adjusting button, a steel wire, a movable spring, and a guide block. The guide frame is symmetrically fixed to the upper end of the lower sleeve at the front end. The adjusting crossbar is fitted with a sleeve in the middle, and torsion springs are symmetrically fixed to the middle section of the inner wall of the sleeve. One end of the torsion spring is fixed to an adjusting button via a connecting rod, and one end of the connecting rod is fixed to one end of the steel wire. The other end of the steel wire is fixed to a movable spring, and one end of the movable spring is fixed to a guide block. The guide block is slidably connected to the inner side of the guide frame and inserted into the opening at the upper part of the inner side of the guide frame.

[0009] Furthermore, the frame structure also includes columns, upper sleeves, and fixed crossbars. The columns are symmetrically fixed to the upper ends of the lower sleeves at the rear end, and the upper sleeves are fixed to the upper ends of the columns. The fixed crossbars are sleeved on the inner side of the upper sleeves.

[0010] Furthermore, the frame structure also includes protruding columns, reinforcing columns, longitudinal rods, collars, and movable rods. The protruding columns are symmetrically fixed through the middle of the front and rear ends of the mounting frame, and a reinforcing column is fixed on the outer side of the front end of the mounting frame. A group of longitudinal rods are symmetrically arranged, and the end of the longitudinal rod is sleeved on one side of the upper sleeve. A collar is sleeved in the middle of the longitudinal rod, and a movable rod is fixed at the lower end of the collar and extends out of the middle of the mounting block.

[0011] Furthermore, it also includes a movable support structure, which includes a support rod and a braked movable wheel. The support rod is symmetrically fixed at the front and rear ends of the mounting block, and the lower end of the support rod is fixed with a braked movable wheel.

[0012] Furthermore, the movable support structure also includes a first support column, a second support column, and a third support column. The second support column and the first support column are respectively sleeved on the lower part of the inner wall of the support rod, and the third support column is sleeved on one side of the support rod.

[0013] Furthermore, it also includes a descent limiting structure, which includes a limiting post, a buzzer, a connecting spring, and a contact block. One end of the limiting post is fixed to the middle of the back of the sleeve. The buzzer is embedded in the upper part of the outer surface of the protruding post. A connecting spring is fixed on the upper end of the buzzer to the push switch, and a contact block is fixed on the upper end of the connecting spring. The upper end of the contact block contacts the other end of the limiting post.

[0014] This utility model has the following beneficial effects:

[0015] I. This utility model utilizes the insertion between the guide block and the top opening on the inner side of the guide frame to ensure the stability of the adjusting crossbar after raising. When lowering the adjusting crossbar, pressing the adjustment button activates the torsion spring, which in turn moves the guide block inward to disengage from the opening. Pressing the adjusting crossbar downward completes the lowering operation. This lifting and adjusting method is time-saving, labor-saving, convenient, and fast, meeting the needs of users.

[0016] II. Based on the above-mentioned beneficial effects, in the process of adjusting the horizontal bar by lowering it, the limiting post is gradually lowered to contact the contact block and the force is transmitted to the connecting spring. After the connecting spring is deformed and gradually compressed until the switch at the top of the buzzer is pressed, the buzzer generated after the switch is turned on is used to indicate that the lowering position of the horizontal bar has reached the limit, so as to avoid deformation and damage to the installation frame caused by the continuous application of force and improve the structural applicability.

Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0026] To make the objectives, technical solutions, and advantages of this utility model clearer, the embodiments of this utility model will be described in further detail below with reference to the accompanying drawings.

[0027] Please see Figure 1-5As shown, this utility model is a baby crib that can be quickly raised and lowered, comprising:

[0028] The frame structure includes a mounting block 11, a mounting frame 12, and a lower sleeve 13. A set of mounting blocks 11 are symmetrically arranged, and the mounting frame 12 is fixedly connected to the center of the inner side of the mounting block 11. The lower sleeve 13 is fixed to the upper corner of the mounting frame 12.

[0029] The mounting block 11, together with the mounting frame 12, provides an installation environment, and the lower sleeve 13 satisfies the installation of the column 14 and the guide frame 21 structure.

[0030] The frame structure also includes columns 14, upper sleeves 15, and fixed crossbars 17. The columns 14 are symmetrically fixed at the upper end of the lower sleeves 13 at the rear end, and the upper sleeves 15 are fixed at the upper end of the columns 14. The fixed crossbars 17 are sleeved on the inner side of the upper sleeves 15.

[0031] The uprights 14 form the side of the crib, and the upper sleeve 15 is fitted and fixed to the horizontal bar 17 and the vertical bar 110.

[0032] The frame structure also includes protruding columns 18, reinforcing columns 19, longitudinal rods 110, collars 111, and movable rods 112. The protruding columns 18 are symmetrically fixed through the middle of the front and rear ends of the mounting frame 12, and the reinforcing columns 19 are fixed on the outer side of the front end of the mounting frame 12. A group of longitudinal rods 110 are symmetrically arranged, and the end of the longitudinal rod 110 is sleeved on one side of the upper sleeve 15. The collar 111 is sleeved in the middle of the longitudinal rod 110, and the movable rod 112 is fixed at the lower end of the collar 111 and extends out of the middle of the mounting block 11.

[0033] The protruding column 18 works in conjunction with the inner edge of the mounting frame 12 to support the mattress. The reinforcing column 19 helps to improve the structural strength of the mounting frame 12. The longitudinal bar 110 forms the upper side of the crib. The collar 111 supports the movable bar 112 and provides side support for the crib.

[0034] The adjustable lifting structure includes a guide frame 21, an adjusting crossbar 22, a sleeve 23, a torsion spring 24, a connecting block 25, an adjusting button 26, a steel wire 27, a movable spring 28, and a guide block 29. The guide frame 21 is symmetrically fixed to the upper end of the lower sleeve 13 at the front end. The sleeve 23 is sleeved in the middle of the adjusting crossbar 22, and the torsion spring 24 is symmetrically fixed in the middle section of the inner wall of the sleeve 23. One end of the torsion spring 24 is fixed to the adjusting button 26 through the connecting rod, and one end of the connecting rod is fixed to one end of the steel wire 27. The other end of the steel wire 27 is fixed to the movable spring 28, and one end of the movable spring 28 is fixed to the guide block 29. The guide block 29 is slidably connected to the inner side of the guide frame 21 and inserted into the opening in the upper part of the inner side of the guide frame 21.

[0035] The guide frame 21 allows the guide block 29 to slide up and down, and is used to adjust the height of the crossbar 22. When the crossbar 22 rises, it forms an isolation barrier; when it falls, it can be used to adapt to the indoor bed. The torsion spring 24 and the connecting block 25 are used in conjunction with the adjustment button 26. By using the elastic force of the torsion spring 24, the adjustment button 26 can be pressed to activate the steel wire 27, which in turn activates the movable spring 28, which in turn activates the guide block 29, causing it to disengage from the opening, thus completing the lowering of the adjustment crossbar 22.

[0036] It also includes a movable support structure, which includes a support rod 31 and a braked movable wheel 32. The support rod 31 is symmetrically fixed at the front and rear ends of the mounting block 11, and the lower end of the support rod 31 is fixed with a braked movable wheel 32.

[0037] The support rod 31 is installed and fixed to the braked movable wheel 32. The movement of the crib is achieved by the rolling between the braked movable wheel 32 and the contact surface.

[0038] The movable support structure also includes a first support column 33, a second support column 35 and a third support column 36. The second support column 35 and the first support column 33 are respectively sleeved on the lower part of the inner wall of the support rod 31, and the third support column 36 is sleeved on one side of the support rod 31.

[0039] The first support column 33, the second support column 35, and the third support column 36 reinforce the lower structure of the crib.

[0040] Working principle: Before using the crib, a protective cloth should be placed around the crib, and a mattress should be placed on the upper part of the protruding column 18 and the mounting frame 12. Then, a pushing force is applied to the crib, and the crib is moved to the side of the indoor bed by the rolling of the braked moving wheels 32 on the ground. It can be used independently. When used with the indoor bed, the adjustment button 26 can be pressed directly. The force is applied to the adjustment button 26. At this time, the torsion spring 24 deforms and is linked to the steel wire 27 to act on the movable spring 28, which in turn acts on the guide block 29, causing the guide block 29 to move into the adjustment bar 22 to disengage from the opening on the upper inner side of the guide frame 21. Then, pressing force is applied to the adjustment bar 22 to complete the lowering adjustment of the adjustment bar 22.

[0041] This solution can simultaneously raise and lower the adjusting bar 22 in one go, saving time and effort, and is convenient and quick, meeting the needs of use.

[0042] Please see Figure 1-5As shown, this embodiment is based on the above embodiment 1, and further includes a descending limiting structure. The descending limiting structure includes a limiting post 41, a buzzer 42, a connecting spring 43, and a contact block 44. One end of the limiting post 41 is fixed to the middle of the back of the sleeve 23. The buzzer 42 is embedded in the upper part of the outer surface of the protrusion 18. The connecting spring 43 is fixed on the upper end of the buzzer 42 and the upper end of the connecting spring 43 is fixed with the contact block 44. The upper end of the contact block 44 contacts the other end of the limiting post 41.

[0043] The connecting spring 43 connects the buzzer 42 to the contact block 44. After the limiting post 41 contacts the contact block 44, it can transmit force to the connecting spring 43. After acting on the buzzer 42, the buzzer 42 switch can be turned on to generate a buzzer and provide a warning of the descending position.

[0044] Working principle: During the descent of the adjusting bar 22, as the limiting post 41 gradually contacts the contact block 44, the force is transmitted to the connecting spring 43. The connecting spring 43 deforms and then transmits the force to the upper end of the buzzer 42 press switch. After the press switch is open, the buzzer 42 sounds to indicate that the adjusting bar 22 has reached the descent position.

[0045] This design avoids the continuous application of force to the mounting frame 12 during the descent of the adjusting crossbar 22, which could cause deformation and damage to the mounting frame 12.

[0046] The preferred embodiments of this utility model disclosed above are merely illustrative of the present utility model. These preferred embodiments do not exhaustively describe all details, nor do they limit the utility model to the specific implementations described. Clearly, many modifications and variations can be made based on the content of this specification.
