Description

Technical Field

[0001] This utility model relates to the field of children's bed technology, specifically a height-adjustable children's bed. Background Technology

[0002] As infants grow from birth to adulthood, their physical development changes continuously. Coupled with the diverse needs of different usage scenarios such as daily family care, nighttime sleep, and living room interaction, the height of cribs becomes particularly important to be flexible and precisely adjustable.

[0003] Traditional cribs, with their fixed height, have significant drawbacks as infants grow and in diverse usage scenarios. From an infant development perspective, during the newborn period, parents frequently need to bend over to check on and care for their babies. If the fixed-height crib is too high, prolonged bending can cause back pain. As the baby grows older, parents may need to take the baby out of the crib for interaction, diaper changes, etc. If the crib height is unsuitable, it is not only inconvenient but may also lead to safety issues due to improper holding posture. In different home environments, such as bedrooms, if the bed is high and a fixed-height crib is placed beside it, the significant drop when parents lift the baby from the bed to the crib can cause uneven arm strength, increasing the risk of injury and greatly impacting the overall user experience, failing to meet current needs. Utility Model Content

[0004] The purpose of this invention is to provide a height-adjustable crib to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a height-adjustable crib, comprising a crib frame, a height adjustment device, and a limiting device, wherein the height adjustment device is disposed at the bottom of the crib frame, and the limiting device is disposed on the surface of the height adjustment device.

[0006] The height adjustment device consists of a slide rod, a support leg, a connecting plate, a threaded rod, a threaded sleeve, a first bevel gear, a fixed plate, a fixed block, a rotating shaft, and a second bevel gear. The slide rod is fixedly installed at the bottom of the bed frame. The support leg is slidably installed on the outside of the slide rod. The connecting plate is fixedly installed on the surface of the support leg. The threaded rod is rotatably installed inside the connecting plate. The threaded sleeve is threadedly installed on the outside of the threaded rod. The first bevel gear is fixedly installed at the bottom of the threaded rod. The fixed plate is fixedly installed on the surface of the connecting plate. The fixed block is fixedly installed at the bottom of the fixed plate. The rotating shaft is rotatably installed inside the fixed block. The second bevel gear is fixedly installed at the left end of the rotating shaft.

[0007] The limiting device consists of a fixed cylinder, a slider, a limiting post, a moving rod, and a spring. The fixed cylinder is fixedly installed on the side of the right front support leg. The slider is slidably installed inside the fixed cylinder. The limiting post is fixedly installed at one end of the slider. The moving rod is fixedly installed at the other end of the slider. The spring is sleeved on the surface of the moving rod.

[0008] Preferably, the top of the threaded sleeve is fixedly connected to the bed frame, and the bed frame can be raised and lowered through the threaded sleeve.

[0009] Preferably, the first bevel gear and the second bevel gear mesh. When the shaft starts to rotate, the second bevel gear, which is fixedly connected to it, is driven. Since the first bevel gear and the second bevel gear are in a perpendicular and staggered meshing state, the rotational power of the second bevel gear is transmitted to the first bevel gear, driving it to rotate synchronously. The second bevel gear is also coaxially connected to the threaded rod. Thus, under the synergistic effect of the two, the threaded rod can be smoothly and stably rotated.

[0010] Preferably, a crank handle is fixedly installed at the right end of the rotating shaft, which can drive the rotating shaft to rotate.

[0011] Preferably, the sliding rod at the front right end has a limiting groove inside that matches the limiting post. The sliding rod can be adjusted to different heights according to actual needs. At this time, the limiting post precisely matches the limiting groove on the sliding rod. When the sliding rod is adjusted to the correct position, the limiting post is inserted into the corresponding limiting groove to form a stable limiting connection, effectively preventing the sliding rod from shifting due to external force and firmly fixing the sliding rod at different heights.

[0012] Preferably, one end of the spring abuts against the fixed cylinder, and the other end of the spring abuts against the slider. When the slider is displaced along the fixed cylinder under the action of external force, the spring, by virtue of its own elastic potential energy, can quickly and stably provide a reverse force to the slider, causing the slider to return to its initial position.

[0013] Preferably, a handle is fixedly installed at the right end of the movable rod, and the movable rod can be moved by the handle.

[0014] Compared with the prior art, the beneficial effects of this utility model are: the height-adjustable crib can be moved by pulling the handle to drive the moving rod, so that the limiting post is disengaged from the limiting groove. The crank handle drives the rotating shaft to rotate, which can cause the threaded sleeve to drive the bed frame to rise and fall. When the handle is released, the limiting post can be inserted into the corresponding limiting groove under the action of the spring. The crib frame at different heights can be fixed, and the use effect is good. Attached Figure Description

Detailed Implementation

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. 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.

[0021] Please see Figure 1-4 This utility model provides a technical solution: a height-adjustable crib, including a bed frame 1, a height adjustment device 2, and a limiting device 3. The height adjustment device 2 is disposed at the bottom of the bed frame 1, and the limiting device 3 is disposed on the surface of the height adjustment device 2.

[0022] The height adjustment device 2 consists of a slide rod 201, a support leg 202, a connecting plate 203, a threaded rod 204, a threaded sleeve 205, a first bevel gear 206, a fixing plate 207, a fixing block 208, a rotating shaft 209, and a second bevel gear 210. The slide rod 201 is fixedly installed at the bottom of the bed frame 1. The support leg 202 is slidably installed on the outside of the slide rod 201. The connecting plate 203 is fixedly installed on the surface of the support leg 202. The threaded rod 204 is rotatably installed inside the connecting plate 203. The threaded sleeve 205 is threadedly installed on the outside of the threaded rod 204. The top of the threaded sleeve 205 is fixedly connected to the bed frame 1, allowing the bed frame 1 to be raised and lowered via the threaded sleeve 205. The first bevel gear 206 is fixedly installed at the bottom of the threaded rod 204. The fixing plate 207 is fixedly installed on the connecting plate 209. On the surface of 03, a fixing block 208 is fixedly installed at the bottom of a fixing plate 207. A rotating shaft 209 is rotatably installed inside the fixing block 208. A crank is fixedly installed at the right end of the rotating shaft 209, which can drive the rotating shaft 209 to rotate. A second bevel gear 210 is fixedly installed at the left end of the rotating shaft 209. The first bevel gear 206 and the second bevel gear 210 mesh. When the rotating shaft 209 starts to rotate, the second bevel gear 210 fixedly connected to it is driven. Since the first bevel gear 206 and the second bevel gear 210 are in a perpendicular and staggered meshing state, the rotational power of the second bevel gear 210 is transmitted to the first bevel gear 206, driving it to rotate synchronously. The second bevel gear 210 is coaxially connected to the threaded rod 204. Thus, under the synergistic action of the two, the threaded rod 204 can be smoothly and stably rotated.

[0023] The limiting device 3 consists of a fixed cylinder 301, a slider 302, a limiting post 303, a moving rod 304, and a spring 305. The fixed cylinder 301 is fixedly installed on the side of the right front support leg 202. The slider 302 is slidably installed inside the fixed cylinder 301. The limiting post 303 is fixedly installed at one end of the slider 302. The inside of the right front slider 201 has a limiting groove that matches the limiting post 303. The slider 201 can be adjusted to different heights according to actual needs. At this time, the limiting post 303 precisely matches the limiting groove on the slider 201. When the slider 201 is adjusted to the correct position, the limiting post 303 is inserted into the corresponding limiting groove to form a stable limiting connection. Effectively prevents the slider 201 from shifting due to external force, and steadily fixes the slider 201 at different heights. The moving rod 304 is fixedly installed at the other end of the slider 302. A handle is fixedly installed at the right end of the moving rod 304. The moving rod 304 can be moved by the handle. The spring 305 is sleeved on the surface of the moving rod 304. One end of the spring 305 abuts against the fixed cylinder 301, and the other end of the spring 305 abuts against the slider 302. When the slider 302 shifts along the fixed cylinder 301 under the action of external force, the spring 305 can quickly and stably provide a reverse force to the slider 302 by virtue of its own elastic potential energy, so that the slider 302 returns to the initial position.

[0024] In use, pulling the handle moves the moving rod 304, causing the limiting post 303 to disengage from the limiting groove. The crank handle drives the rotating shaft 209 to rotate. Under the action of the first bevel gear 206 and the second bevel gear 210, the threaded rod 204 can rotate. Under the guidance of the slide rod 201, the threaded sleeve 205 can drive the bed frame 1 to rise and fall. Releasing the handle allows the limiting post 303 to be inserted into the corresponding limiting groove under the action of the spring 305, effectively preventing the slide rod 201 from shifting due to external force. This allows the bed frame 1 at different heights to be fixed.
