Description

Technical Field

[0001] This utility model relates to the field of fuse production equipment technology, and in particular to a folding bed. Background Technology

[0002] A crib is a bed used by infants and toddlers to provide them with a safe sleeping or play environment. However, cribs can also pose some safety hazards, which parents should pay attention to and address promptly. When choosing a crib, it's important to consider both safety and practicality.

[0003] Existing folding cribs have a base in the middle with multiple supports hinged to it. Limiting parts are set on the base to block the corresponding supports in the appropriate position, which helps to support the mesh fabric. However, this method only limits the unfolded position and cannot fix the supports. If you hook one support and pull it up, it is easy to accidentally fold the support. In addition, each support swings independently, so each support needs to be folded individually when unfolding or folding, which is inefficient. Utility Model Content

[0004] To address the aforementioned problems, the purpose of this utility model is to provide a folding bed with a central section.

[0005] This utility model is implemented using the following method: a folding bed-in-bed includes two bases arranged symmetrically side by side. Multiple supports are hinged to both sides of each base. A linkage component connects the multiple supports on the same side of each base. Two supports opposite each other on the same side of the two bases are connected as one unit so that the multiple supports on the same side of the base can be linked. A first limiting part is connected to the base. Limiting rods are connected to the supports on both sides of the base. A second limiting part is provided at the end of all the limiting rods away from the support. The second limiting part cooperates with the first limiting part to fix the support.

[0006] Preferably, two brackets are hinged to each side of the base, and a linkage component is provided on each side of the base, the linkage component being connected between the two brackets on the same side and the base.

[0007] Preferably, the linkage assembly includes two linkage rods, one end of which is hinged to the bottom support of the base, and the other end is movably connected to a support hinged to the middle of the base; the other linkage rod is hinged to the upper part of the base, and the other end is movably connected to a support hinged to the middle of the base.

[0008] Preferably, the linkage assembly further includes a sliding sleeve fitted onto a bracket hinged in the middle of the base, and both linkage rods are hinged to the bracket through the sliding sleeve.

[0009] Preferably, the hinge points of the two linkage rods and the sliding sleeve are coaxial.

[0010] Preferably, the linkage assembly further includes a sliding groove on a bracket hinged to the center of the base, and two linkage rods are slidably connected to the sliding groove, with the two linkage rods hinged to each other at the sliding groove.

[0011] Preferably, the first limiting part is a spring piece disposed on the base, the spring piece is provided with a limiting hole, the limiting rod is hinged to the bracket, and the second limiting part is a snap-fit ​​shaft disposed at the end of the limiting rod away from the hinge point with the bracket, the snap-fit ​​shaft can snap into the limiting hole.

[0012] Preferably, the top of the spring piece has a curved surface that bends away from the other base, and the limiting hole is located on the curved surface.

[0013] Preferably, a limiting rod is provided on both sides of the same base, the limiting rod is hinged to one of the brackets on the same side, and the limiting rods on both sides of the same base are hinged to each other. The hinge point of the two limiting rods is coaxial with the locking shaft, and the two mutually hinged limiting rods share a locking shaft.

[0014] Preferably, two brackets are hinged to each side of the base, one bracket being hinged to the bottom of the base and the other bracket being hinged to the middle of the base; the limiting rod is hinged to the bracket hinged to the bottom of the base, and the limiting rods on both sides of the base are symmetrically arranged.

[0015] The beneficial effects of this utility model are as follows: This utility model provides a folding bed with a middle section, which, compared with the prior art, has at least the following technical effects: 1. The linkage component allows multiple supports on the same side to swing synchronously, eliminating the need to operate each support individually during folding, significantly improving operational efficiency; through the cooperation of the first limiting part, the limiting rod, and the second limiting part thereon, the folding bed can be fixed after unfolding, and can only be folded when the first and second limiting parts are disengaged. 2. A linkage component connects the supports on the same side, facilitating the operation of the supports on one side by both hands, which is beneficial for quick unfolding or folding. 3. Two linkage rods, the base, and the supports on the same side form a parallelogram linkage structure; rotating one support will also cause the other support to rotate, realizing the linkage of multiple supports and enabling quick folding and unfolding of the folding bed. 4. A sliding sleeve is added to the middle support, making the connection and sliding between the linkage rod and the support smoother, thus eliminating the need to drill holes in the support and ensuring the structural strength of the support. 5. The first limiting part is designed as a spring piece fixed to the base. A limiting hole is provided on the spring piece, which cooperates with the locking shaft of the limiting rod. The spring piece can deform to facilitate the locking shaft to engage or disengage, making it convenient to fix or fold the folding bed after unfolding. 6. The top of the spring piece has an outward curved surface, and the limiting hole is located at the curved surface. The curved surface guides the locking shaft to slide into the limiting hole, reducing the difficulty of alignment. Simply grasp one side of the bracket with both hands and pull outward to unfold the bracket while the locking shaft slides into the limiting hole. 7. The limiting rods on both sides share a locking shaft, achieving simultaneous locking on both sides in one operation. 8. The limiting rods are connected to the bottom bracket and are symmetrically arranged. The bottom bracket serves as the main load-bearing point, and the symmetrical locking of the limiting rods enhances the base's anti-tipping ability. Attached Figure Description

[0022] The following further describes the present utility model in conjunction with the accompanying drawings and specific embodiments.

[0023] Please refer to Figures 1 to 5 , a middle bed of a folding bed, including two bases 1 symmetrically arranged side by side. A plurality of brackets 2 are respectively hinged on both sides of each base 1. A linkage component is connected between the plurality of brackets 2 on the same side of each base 1. Two opposite brackets 2 on the same side of the two bases 1 are integrally connected, so that the plurality of brackets 2 on the same side of the base 1 are linked; a first limiting portion is connected to the base 1, limiting rods 3 are respectively connected to the brackets 2 on both sides of the base 1, and a second limiting portion is provided at one end of all the limiting rods 3 away from the brackets 2. The second limiting portion and the first limiting portion cooperate to fix the brackets 2. The setting of the linkage component enables the plurality of brackets 2 on the same side to swing synchronously. When folding, there is no need to operate each bracket 2 separately, significantly improving the operation efficiency; through the cooperation of the first limiting portion, the limiting rod 3 and the second limiting portion thereon, the folding bed can be fixed after being unfolded, and the folding bed can be folded only by separating the first limiting portion and the second limiting portion from contacting each other.

[0024] Please refer to Figures 1 to 5 , preferably, two brackets 2 are hinged on each side of the base 1, and a linkage component is provided on each side of the base 1. The linkage component is connected between the two brackets 2 and the base 1 on the same side. A linkage component is connected between the brackets 2 on the same side, which is convenient for operating the brackets 2 on one side with both hands respectively, and is beneficial to quickly unfold or fold. More brackets 2 can also be provided according to needs, and corresponding sliding sleeves 5 and linkage rods 4 can be added

[0025] Please refer to Figures 1 to 5 , preferably, the linkage component includes two linkage rods 4. One end of one linkage rod 4 is hinged to the bracket 2 at the bottom of the base 1, and the other end is movably connected to the bracket 2 hinged to the middle of the base 1; the other linkage rod 4 is hinged to the upper part of the base 1, and the other end is movably connected to the bracket 2 hinged to the middle of the base 1. The two linkage rods 4 and the base 1 and the brackets 2 on the same side form a parallelogram linkage structure. Only by rotating one bracket 2, the other bracket 2 will also be driven to rotate, realizing the linkage of the plurality of brackets 2, and enabling the folding bed to be quickly folded and unfolded.

[0026] Please refer to Figures 1 to 5Preferably, the linkage assembly further includes a sliding sleeve 5 fitted onto a bracket 2 hinged to the middle of the base 1, and both linkage rods 4 are hinged to the bracket 2 via the sliding sleeve 5. Adding the sliding sleeve 5 to the middle bracket 2 makes the connection and sliding between the linkage rods 4 and the bracket 2 smoother, thus eliminating the need to drill holes in the bracket 2 and ensuring the structural strength of the bracket 2.

[0027] Please see Figures 1 to 5 Preferably, the hinge points of the two linkage rods 4 and the sliding sleeve 5 are coaxial, forming a parallelogram to facilitate the synchronous rotation of the two supports 2.

[0028] Please see Figures 1 to 5 Preferably, the linkage assembly further includes a sliding groove on a bracket 2 hinged to the middle of the base 1, and two linkage rods 4 are slidably connected to the sliding groove, with the two linkage rods 4 hinged to each other at the sliding groove. It can also form a quadrilateral structure, where a change in position on one side causes a synchronous change in the others, achieving linkage.

[0029] Please see Figures 1 to 5 Preferably, the first limiting part is a spring piece 6 disposed on the base 1, the spring piece 6 having a limiting hole 7, the limiting rod 3 being hinged to the bracket 2, and the second limiting part is a snap-fit ​​shaft 8 disposed at the end of the limiting rod 3 away from the hinge point with the bracket 2, the snap-fit ​​shaft 8 being able to snap into the limiting hole 7. Designing the first limiting part as a spring piece 6 fixed on the base 1, with a limiting hole 7 on the spring piece 6, allows it to cooperate with the snap-fit ​​shaft 8 of the limiting rod 3. The spring piece 6 can deform to facilitate the snap-fit ​​shaft 8 snapping in or out, making it convenient for the folding bed to be fixed or folded up after unfolding.

[0030] Please see Figures 1 to 5 Preferably, the top of the spring piece 6 has a curved surface that bends away from the other base 1, and the limiting hole 7 is located on the curved surface. The top of the spring piece 6 has an outward curved surface, and the limiting hole 7 is located on the curved surface. The curved surface guides the locking shaft 8 to slide into the limiting hole 7, reducing the difficulty of alignment. Simply hold one side of the bracket 2 with both hands and pull it outward to unfold the bracket 2 while the locking shaft 8 slides into the limiting hole 7.

[0031] Please see Figures 1 to 5 Preferably, a limiting rod 3 is provided on both sides of the same base 1. The limiting rod 3 is hinged to one of the brackets 2 on the same side, and the limiting rods 3 on both sides of the same base 1 are hinged to each other. The hinge point of the two limiting rods 3 is coaxial with the locking shaft 8, and the two mutually hinged limiting rods 3 share a locking shaft 8. The limiting rods 3 on both sides share the locking shaft 8, and double-sided synchronous locking is achieved in one operation.

[0032] Please see Figures 1 to 5Preferably, two supports 2 are hinged to each side of the base 1, one support 2 is hinged to the bottom of the base 1, and the other support 2 is hinged to the middle of the base 1; the limiting rod 3 is hinged to the support 2 hinged to the bottom of the base 1, and the limiting rods 3 on both sides of the base 1 are symmetrically arranged. The limiting rods 3 connect to the bottom support 2 and are symmetrically arranged. The bottom support 2 serves as the main load-bearing point, and the symmetrical locking by the limiting rods 3 enhances the anti-overturning ability of the base 1.

[0033] Please see Figures 1 to 5 Preferably, the two supports 2 on the same side of the two bases 1 are connected together at the ends away from the hinge point to form two U-shaped frames. In the folded state, one frame is located inside the other frame. Four hinge points are symmetrically arranged on both sides of the base 1, with two arranged side by side on each side. The bottom hinge point is on the inside of the base 1, and the top hinge point is on the outside of the base 1. This staggered hinge method avoids interference between the support 2, the limiting rod 3, and the linkage rod 4.

[0034] The working principle of this utility model is as follows:

[0035] Folding steps: Press the locking shafts 8 out of the limiting holes 7 of the two spring clips 6. With both hands, from bottom to top, fold the bottommost brackets 2 on both sides of the base 1 together from both sides towards the middle. When the upper bracket 2 in the unfolded state is almost perpendicular to the ground, the folding is complete. Figure 5 As shown.

[0036] Unfolding steps: With both hands, unfold the upper support 2 outwards. When the lower support 2 touches the ground, press the locking shafts 8 of the limiting rods 3 of the two bases 1 into the corresponding limiting holes 7 of the spring pieces 6 to complete the unfolding. Figure 3 As shown.

[0037] The structural design is based on the stability of a triangle. When folding, the locking shaft 8 is pushed out of the limiting hole 7, releasing the stability of the large triangle. The lowermost bracket 2 is lifted upwards, causing the linkage rod 4, hinged to the lowermost bracket 2, to push the sliding sleeve 5 upwards on the upper bracket 2. The linkage rod 4, hinged to the base 1, pulls the upper bracket 2 upwards during unfolding, folding it up until it is nearly perpendicular to the ground. During unfolding, the upper bracket 2 is unfolded to both sides. The two linkage rods 4, hinged to the base 1, work together to pull the sliding sleeve 5 downwards along the bracket 2, thereby driving the linkage rod 4, hinged to the lower bracket 2, to push the lower bracket 2 downwards. After unfolding to the desired position, the locking shaft 8 is pressed into the limiting hole 7. At this point, the limiting rod 3, the base 1, and the lower bracket 2 form a large triangle stability lock, and the entire structure is in a stable state, completing the unfolding process.
