Description

Technical Field

[0001] This utility model relates to the field of children's furniture technology, and in particular to a children's bed with adjustable railings. Background Technology

[0002] Children's furniture refers to home furnishing products specifically designed and manufactured for children, encompassing various types such as beds, desks, wardrobes, and storage cabinets. This type of furniture is designed with children's height and dimensions in mind. In terms of safety, children's furniture adheres to strict requirements, using environmentally friendly and non-toxic materials, avoiding sharp edges to prevent bumps and injuries, and featuring a sturdy structure to prevent the risk of tipping over.

[0003] Some existing children's beds have a relatively simple design with a fixed height. The placement and height of the children's bed and the parents' bed are not matched, making it difficult for parents to notice abnormalities (such as turning over or crying) in time. They need to frequently adjust their posture, which affects the quality of their rest. Moreover, as children grow taller, traditional fixed-height children's beds cannot provide enough space for standing and playing. This may cause children to bump into the railings or the top of the bed while playing, which restricts their autonomy. Therefore, in order to solve the above problems, a children's bed with adjustable railings is proposed. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of traditional children's beds in the prior art, namely that the height and activity area are not adjustable, and to propose a children's bed with adjustable enclosure.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] An adjustable-enclosure children's bed includes a movable frame with a base plate mounted on top of the movable frame. The height of the base plate is adjustable. The movable frame is provided with an adjustment mechanism for the base plate. The adjustment mechanism includes a lifting cylinder and a lifting screw disposed inside the lifting cylinder. The lifting screw is used to raise the height of the base plate.

[0007] A surrounding fence is slidably disposed on the outer side of the base plate. The surrounding fence can move up and down. An adjusting screw for moving the surrounding fence is installed on the outer side of the surrounding fence. A side fence is rotatably disposed on the outer side of the base plate. A locking mechanism is provided on the base plate for fixing the side fence.

[0008] The above technical solution further includes:

[0009] The adjustment mechanism also includes a rotating handle, which is rotatably mounted on the inner side of a mounting plate fixedly connected to the movable frame. A limit cylinder is fixedly connected to the top of the mounting plate, and the lifting screw is rotatably connected to the mounting plate.

[0010] The inner wall of the limiting cylinder is provided with a protrusion, and the outer wall of the lifting cylinder is provided with a groove, and the lifting cylinder and the limiting cylinder slide relative to each other.

[0011] A threaded ring is fixedly connected to the bottom of the lifting cylinder, and the threaded ring is threadedly connected to the lifting screw.

[0012] The rotating handle is fixedly connected to a driving bevel gear at one end near the lifting screw, and a driven bevel gear is fixedly connected to the other end of the lifting screw near the driving bevel gear. The driving bevel gear and the driven bevel gear mesh with each other.

[0013] A sliding frame is fixedly connected to the outer side of the base plate. The sliding frame slides relative to the fence plate. A rotating block is fixedly connected to the outer side of the sliding frame. A threaded block is fixedly connected to the outer side of the fence plate. The threaded block is threadedly connected to the adjusting screw. The rotating block is rotatably connected to the adjusting screw. A support slide rod is installed on the side of the sliding frame and the fence plate away from the adjusting screw.

[0014] The top of the mobile frame is slidably provided with multiple sliding rods, which are fixedly connected to the base plate. A baffle is fixedly connected to one side of the base plate, and a rotating rod is rotatably connected to the side of the base plate near the baffle. The rotating rod is rotatably connected to the side grid plate.

[0015] The locking mechanism includes a pawl, ratchet wheels are fixedly connected to both sides of the rotating rod, support plates are fixedly connected to both sides of the baffle, and a pawl is rotatably connected to the support plate, with the pawl and ratchet wheels engaging with each other.

[0016] This utility model has the following beneficial effects:

[0017] In this invention, the height of the base plate is adjustable by using a lifting screw and a lifting cylinder, which can accommodate the different bed heights of parents in different families. This eliminates the inconvenience of bending over and stepping when parents are taking care of children due to height differences, improves the efficiency of nighttime monitoring and emergency response, meets the needs of children at different growth stages for bed height, and extends the product's service life.

[0018] In this invention, the fence panel can slide up and down and is controlled by an adjusting screw, the side fence panel can rotate and is fixed by a locking mechanism, and parents can flexibly adjust the height and shape of the fence according to the child's age. The side fence panel can be adjusted in angle, thereby adjusting the child's activity area. Attached Figure Description

[0026] 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.

[0027] Example

[0028] like Figures 1-6 As shown, the present invention proposes an adjustable children's bed with adjustable enclosure, including a movable frame 1, a base plate 3 installed on the top of the movable frame 1, the height of the base plate 3 being adjustable, and an adjustment mechanism for the base plate 3 provided on the movable frame 1. The adjustment mechanism includes a lifting cylinder 42 and a lifting screw 43 provided inside the lifting cylinder 42. The lifting screw 43 is used to raise the height of the base plate 3.

[0029] A fence plate 20 is slidably provided on the outer side of the base plate 3. The fence plate 20 can move up and down. An adjusting screw 22 for moving the fence plate 20 is installed on the outer side of the fence plate 20. A side fence plate 31 is rotatably provided on the outer side of the base plate 3. A locking mechanism is provided on the base plate 3 for fixing the side fence plate 31.

[0030] Furthermore, when the height of the base plate 3 needs to be adjusted, the user can rotate the lifting screw 43 inside the lifting cylinder 42. Utilizing the helical transmission characteristics of the thread, the rotational motion of the lifting screw 43 is converted into the vertical lifting motion of the base plate 3. For example, rotating the lifting screw 43 clockwise causes the engagement of the lifting screw 43 with the thread to push the base plate 3 upward, while rotating it counterclockwise lowers the height.

[0031] Furthermore, the up-and-down movement of the fence panel 20 is achieved through an adjusting screw 22 installed on its outer side. When the user rotates the adjusting screw 22, the fence panel 20 can slide up and down. When the child is young and requires higher protection, rotating the adjusting screw 22 clockwise raises the fence panel 20 to increase the height of the enclosure; when a parent is supervising, rotating the adjusting screw 22 counterclockwise lowers the fence panel 20 to increase the permeability of the bed.

[0032] Furthermore, users can manually rotate the side grille 31 to the desired angle (e.g., close it as a barrier or open it as an entrance to the activity area). Once the side grille 31 is rotated to the target position, its position is secured by a locking mechanism on the base plate 3 to prevent children from pushing it and causing it to loosen. At the same time, the side grille 31 can be laid flat, parallel to the base plate 3, which can increase the activity area for children. Since the side grille 31 is open, parents can also interact with their children more effectively.

[0033] The adjustment mechanism also includes a rotating handle 41, which is rotatably mounted on the inner side of the mounting plate 4 fixedly connected to the movable frame 1. A limit cylinder 40 is fixedly connected to the top of the mounting plate 4, and the lifting screw 43 is rotatably connected to the mounting plate 4.

[0034] The inner wall of the limiting cylinder 40 is provided with a protrusion, and the outer wall of the lifting cylinder 42 is provided with a groove, and the lifting cylinder 42 and the limiting cylinder 40 slide relative to each other.

[0035] A threaded ring 44 is fixedly connected to the bottom of the lifting cylinder 42, and the threaded ring 44 is threadedly connected to the lifting screw 43;

[0036] A drive bevel gear 45 is fixedly connected to one end of the rotating handle 41 near the lifting screw 43, and a driven bevel gear 46 is fixedly connected to one end of the lifting screw 43 near the drive bevel gear 45. The drive bevel gear 45 and the driven bevel gear 46 mesh with each other.

[0037] Furthermore, the height adjustment mechanism of the children's bed base 3 is achieved through the following components: a rotating handle 41 is rotatably mounted inside the mounting plate 4 of the movable frame 1, with one end near the lifting screw 43 fixedly connected to a driving bevel gear 45, and the other end of the lifting screw 43 near the driving bevel gear 45 fixedly connected to a driven bevel gear 46, the two transmitting power through gear meshing; the inner wall of the limiting cylinder 40 fixedly connected to the top of the mounting plate 4 has a protrusion, which cooperates with the groove on the outer wall of the lifting cylinder 42 to form a sliding guide structure, ensuring that the lifting cylinder 42 can only slide vertically along the axial direction of the limiting cylinder 40; the bottom of the lifting cylinder 42 is fixedly connected to The threaded ring 44 is threadedly connected to the lifting screw 43. When the user rotates the handle 41, the driving bevel gear 45 drives the driven bevel gear 46 and the lifting screw 43 to rotate synchronously. At this time, the threaded ring 44 converts the rotational motion into the linear motion of the lifting cylinder 42 due to the threaded engagement. Since the protrusion of the limiting cylinder 40 and the groove of the lifting cylinder 42 restrict the degree of rotational freedom, the lifting cylinder 42 can only rise or fall axially, thereby driving the base plate 3 installed on its top to achieve height adjustment. This design, through the combination of bevel gear transmission and threaded lifting, not only ensures the accuracy of adjustment, but also improves safety through the limiting structure.

[0038] A sliding frame 2 is fixedly connected to the outer side of the base plate 3. The sliding frame 2 slides relative to the fence plate 20. A rotating block 21 is fixedly connected to the outer side of the sliding frame 2. A threaded block 23 is fixedly connected to the outer side of the fence plate 20. The threaded block 23 is threadedly connected to the adjusting screw 22. The rotating block 21 is rotatably connected to the adjusting screw 22. A support sliding rod 24 is installed on the side of the sliding frame 2 and the fence plate 20 away from the adjusting screw 22.

[0039] Multiple sliding rods 10 are slidably arranged on the top of the mobile frame 1. The multiple sliding rods 10 are fixedly connected to the base plate 3. A baffle 30 is fixedly connected to one side of the base plate 3. A rotating rod 35 is rotatably connected to the side of the base plate 3 near the baffle 30. The rotating rod 35 is rotatably connected to the side grid plate 31.

[0040] Furthermore, the height adjustment of the side rails 20 and the opening and closing function of the side rails 31 of the children's bed are achieved through the following components: the slide rail frame 2 fixedly connected to the outside of the base plate 3 and the side rails 20 form a guide structure through sliding engagement; the threaded block 23 fixedly connected to the outside of the side rails 20 is threadedly connected to the adjusting screw 22; and the rotating block 21 on the outside of the slide rail frame 2 is rotatably connected to the adjusting screw 22. When the user rotates the adjusting screw 22, the rotating block 21 restricts the axial movement of the adjusting screw 22, and the threaded block 23 converts the rotational motion into the linear sliding of the side rails 20 along the slide rail frame 2 due to the threaded engagement, thereby adjusting the height of the side rails 20.

[0041] Furthermore, the support slide rod 24, which is installed on the side of the slide frame 2 and the fence plate 20 away from the adjusting screw 22, further improves the stability of the fence plate 20 when it slides; multiple slide rods 10, which are slidably set on the top of the movable frame 1, are fixedly connected to the base plate 3. When the base plate 3 moves up and down due to the adjusting mechanism, the slide rods 10 slide synchronously on the top of the movable frame 1 to ensure the smoothness of the lifting and lowering of the base plate 3.

[0042] Furthermore, the baffle 30 fixedly connected to one side of the base plate 3 serves as a limiting reference when the side grid 31 is closed. The rotating rod 35 rotatably connected to the side of the base plate 3 near the baffle 30 is rotatably connected to the side grid 31. Users can push the side grid 31 to make it rotate around the rotating rod 35 to open and close the side grid 31. When closed, the side grid 31 and the baffle 30 fit together to form a complete enclosure. When open and closed, it expands the activity space of the children's bed. This design, through the combination of sliding adjustment and rotating opening and closing, not only meets the safety protection needs of children at different growth stages, but also improves the convenience of operation for parents.

[0043] The locking mechanism includes a pawl 34, ratchet 32 ​​fixedly connected to both sides of the rotating rod 35, support plate 33 fixedly connected to both sides of the baffle 30, and pawl 34 rotatably connected to the support plate 33. The pawl 34 and ratchet 32 ​​are in contact with each other.

[0044] Furthermore, when the user pushes the side grille 31 to rotate and close around the rotating rod 35, the rotating rod 35 drives the ratchet 32 ​​to rotate synchronously. At this time, the pawl 34 slides on the back of the teeth of the ratchet 32, which does not hinder the rotational movement of the ratchet 32, allowing the side grille 31 to close smoothly until it fits against the baffle 30 to form a complete enclosure. After the side grille 31 is closed, if a child tries to push the side grille 31 to make it rotate in the opposite direction, the ratchet 32 ​​will have a tendency to rotate in the opposite direction, but because the pawl 34 is engaged with the teeth of the ratchet 32... The pawl 34 will prevent the ratchet 32 ​​from rotating in the opposite direction, thereby locking the position of the lever 35 and preventing the side gate 31 from opening accidentally. When it is necessary to open the side gate 31, the user needs to manually move the pawl 34 to disengage it from the tooth groove of the ratchet 32 ​​and release the lock on the ratchet 32. Only then can the side gate 31 be pushed to rotate around the lever 35 to open. This design effectively improves the safety of the side gate 31 in the closed state through the one-way locking characteristics of the ratchet and pawl, and prevents children from accidentally operating it and causing the barrier to fail.

[0045] In this embodiment, the height adjustment of the base plate 3 is accomplished by the adjustment mechanism. The user rotates the handle 41 on the mounting plate 4, and the lifting screw 43 is driven to rotate through the meshing of the active bevel gear 45 and the driven bevel gear 46. The lifting screw 43 cooperates with the threaded ring 44 at the bottom of the lifting cylinder 42, so that the lifting cylinder 42 slides along the axial direction of the limiting cylinder 40, thereby driving the base plate 3 to rise and fall, so that the base plate 3 can be level with the height of the parent bed, making it convenient for the parent to take care of the child.

[0046] The height of the fence panel 20 is adjusted via a sliding frame 2 and an adjusting screw 22. When the adjusting screw 22 is rotated, the threaded block 23 drives the fence panel 20 to slide along the sliding frame 2, supporting the sliding rod 24 to improve stability. The side fence panel 31 is rotatably connected to the baffle 30 via a rotating rod 35. When closed, the ratchet 32 ​​rotates with the rotating rod 35, and the pawl 34 engages with the tooth groove of the ratchet 32 ​​on the support plate 33, forming a one-way lock to prevent the side fence panel 31 from opening accidentally. To open, the pawl 34 must be manually moved to unlock. This design takes into account both the safety protection needs of children at different stages of growth and the convenience of operation for parents.
