Description

Technical Field

[0001] The utility model relates to the technical field of children's beds, in particular to a connecting rod assembly and a bed frame of a foldable children's bed. Background Art

[0002] A bedside bed is a type of children's bed that can be placed right next to an adult's bed, making it easier for adults to keep an eye on the child. For ease of transport and storage, it's often foldable. When not in use, the sides of the bed fold together, creating a compact, space-saving design.

[0003] In a children's bed, the mattress is mounted on a bed tube assembly that supports it. A connecting rod assembly is located below the bed tube assembly. When the children's bed is folded, the bed tube assembly and the connecting rod assembly fold accordingly. Existing connecting rod assemblies generally consist of three connecting rods that are rotatably connected end to end. When the children's bed is folded, the three connecting rods gradually move from the left and right ends to the center. Although the connecting rod assembly consisting of three connecting rods has a simple structure, the rotation angles of the first connecting rod relative to the second connecting rod and the third connecting rod relative to the second connecting rod are both arbitrary and do not interact. Therefore, during the folding or unfolding process, the left and right sides cannot be folded or unfolded completely synchronously. Utility Model Content

[0004] In view of the above-mentioned deficiencies in the prior art, the technical problem to be solved by the present invention is to provide a connecting rod assembly and a bed frame for a foldable children's bed with synchronous movements on both sides when unfolding and folding.

[0005] The technical solution adopted by the present invention to solve the technical problem is to provide a connecting rod assembly for a foldable children's bed, comprising:

[0006] a left connecting rod, a first intermediate connecting rod, a second intermediate connecting rod and a right connecting rod;

[0007] One end of the left connecting rod can be connected to the left supporting leg of the child bed, and the other end of the left connecting rod is rotatably connected to one end of the first intermediate connecting rod;

[0008] One end of the right connecting rod can be connected to the right supporting leg of the child bed, and the other end of the right connecting rod is rotatably connected to one end of the second intermediate connecting rod;

[0009] One end of the first intermediate link away from the left link is rotatably connected to the right link, and one end of the second intermediate link away from the right link is rotatably connected to the left link;

[0010] When the child bed is folded or unfolded, the left connecting rod and the right connecting rod can be folded or unfolded synchronously.

[0011] Furthermore, the left connecting rod has a first connecting seat at one end close to the first intermediate connecting rod, and the first intermediate connecting rod and the second intermediate connecting rod are both rotatably connected to the first connecting seat.

[0012] Furthermore, the right connecting rod has a second connecting seat at one end close to the second intermediate connecting rod, and the second intermediate connecting rod and the first intermediate connecting rod are both rotatably connected to the second connecting seat.

[0013] Furthermore, the first connecting seat, the second connecting seat, the first intermediate connecting rod and the second intermediate connecting rod are rotatably connected end to end in sequence to form a quadrilateral structure.

[0014] Furthermore, the first connecting seat has a first buckle, the second connecting seat has a second buckle, and the first buckle and the second buckle both have an upward opening, and the bed pipe group of the children's bed can be respectively connected to the first buckle and the second buckle along the opening.

[0015] The technical solution adopted by the present invention to solve the technical problem is to provide a foldable bed frame for children, comprising:

[0016] A left supporting leg and a right supporting leg are arranged at intervals;

[0017] The connecting rod assembly mentioned above, wherein the end of the left connecting rod away from the first intermediate connecting rod is rotatably connected to the left supporting leg, and the end of the right connecting rod away from the second intermediate connecting rod is rotatably connected to the right supporting leg;

[0018] a bed pipe assembly, disposed above the connecting rod assembly, comprising a left bed pipe bracket and a right bed pipe bracket, wherein the left bed pipe bracket is rotatably disposed on the left support leg, and the right bed pipe bracket is rotatably disposed on the right support leg, and the left bed pipe bracket and the right bed pipe bracket are rotatably connected;

[0019] An upper frame, provided on top of the left supporting leg and the right supporting leg;

[0020] The bed frame has an unfolded state and a folded state. When the bed frame is in the unfolded state, the bed pipe assembly rests on the connecting rod assembly.

[0021] Furthermore, when the bed frame is in the unfolded state, the left bed pipe bracket is clamped on the left connecting rod, and the right bed pipe bracket is clamped on the right connecting rod;

[0022] When the bed frame switches from the folded state to the unfolded state, the left bed pipe bracket is disengaged from the left connecting rod, and the right bed pipe bracket is disengaged from the right connecting rod.

[0023] Furthermore, when the bed frame switches from the expanded state to the folded state, the left bed pipe bracket and the right bed pipe bracket both rotate upward, and the connecting rod group drives the left supporting leg and the right supporting leg to move synchronously from the left and right sides to the middle.

[0024] Furthermore, the end of the left connecting rod close to the left supporting leg and the end of the right connecting rod close to the right supporting leg each have a vertical rod section;

[0028] In the present invention, the left and right connecting rods are connected via a first intermediate connecting rod and a second intermediate connecting rod, and both the first and second intermediate connecting rods are rotatably connected to the left and right connecting rods, forming a parallelogram structure. When the left connecting rod rotates, the right connecting rod is driven to rotate synchronously, and when the right connecting rod rotates, the left connecting rod is driven to rotate synchronously. Therefore, when the present invention is used in a foldable child's bed, the left connecting rod is connected to the left support leg, and the right connecting rod is connected to the right support leg. When the child's bed is folded, whether the left supporting leg is folded toward the right supporting leg or the right supporting leg is folded toward the left supporting leg, the other side can be folded synchronously, so that the left and right sides can be folded inward completely and synchronously. Similarly, the left and right sides can also be expanded outward completely and synchronously. BRIEF DESCRIPTION OF THE DRAWINGS

[0055] Example 1:

[0056] like Figure 1 As shown, a connecting rod assembly of a foldable children's bed in this embodiment mainly includes: a left connecting rod 1, a first middle connecting rod 2, a second middle connecting rod 3 and a right connecting rod 4.

[0057] Among them, one end of the left connecting rod 1 can be connected to the left support leg 5 of the child bed, and the other end of the left connecting rod 1 is rotatably connected to one end of the first intermediate connecting rod 2. One end of the right connecting rod 4 can be connected to the right support leg 6 of the child bed, and the other end of the right connecting rod 4 is rotatably connected to one end of the second intermediate connecting rod 3. The end of the first intermediate connecting rod 2 away from the left connecting rod 1 is rotatably connected to the right connecting rod 4, and the end of the second intermediate connecting rod 3 away from the right connecting rod 4 is rotatably connected to the left connecting rod 1. Specifically, the end of the left connecting rod 1 close to the first intermediate connecting rod 2 has a first connecting seat 10 that is separately provided and fixedly connected thereto, and the first intermediate connecting rod 2 and the second intermediate connecting rod 3 are both rotatably connected to the first connecting seat 10; the end of the right connecting rod 4 close to the second intermediate connecting rod 3 has a second connecting seat 40 that is separately provided and fixedly connected thereto, and the second intermediate connecting rod 3 and the first intermediate connecting rod 2 are both rotatably connected to the second connecting seat 40. Furthermore, the first connecting base 10, the second connecting base 40, the first intermediate link 2, and the second intermediate link 3 are rotatably connected end to end to form a parallelogram structure. In actual use, when the child bed is folded or unfolded, the left link 1 and the right link 4 can be folded or unfolded simultaneously, maintaining the same rotation angle of the left link 1 and the right link 4.

[0058] Specifically, in this embodiment, the first connecting base 10 has a first buckle 101, and the second connecting base 40 has a second buckle 401. Both the first buckle 101 and the second buckle 401 have an upward-facing opening, along which the bed tube assembly 7 of the child's crib can be respectively attached to the first buckle 101 and the second buckle 401. More specifically, the first buckle 101 is attached to the left bed tube bracket 71 of the bed tube bracket 7, and the second buckle 401 is attached to the right bed tube bracket 72 of the bed tube bracket 7.

[0059] Combine Figure 2-Figure 8 As shown, in the connecting rod assembly of this embodiment, the left connecting rod 1 and the right connecting rod 4 are connected by a first intermediate connecting rod 2 and a second intermediate connecting rod 3. Both the first intermediate connecting rod 2 and the second intermediate connecting rod 3 are rotatably connected to the left connecting rod 1 and the right connecting rod 4, forming a parallelogram structure. When the left connecting rod 1 rotates, it can drive the right connecting rod 4 to rotate synchronously, and when the right connecting rod 4 rotates, it can drive the left connecting rod 1 to rotate synchronously. Therefore, when used in a foldable child's bed, the left connecting rod 1 is connected to the left support leg 5, and the right connecting rod 4 is connected to the right support leg 6. When the child's bed is folded, whether the left supporting leg 5 is folded toward the right supporting leg 6 or the right supporting leg 6 is folded toward the left supporting leg 5, the other side can be folded synchronously, so that the left and right sides can fold inward completely and synchronously. Similarly, the left and right sides can also be deployed outward completely and synchronously, and the deployment and folding efficiency is also high.

[0060] Example 2:

[0061] like Figures 9-12As shown, the bed frame of a foldable children's bed in this embodiment mainly includes the following structures:

[0062] The left supporting leg 5 and the right supporting leg 6 are spaced apart; wherein the left supporting leg 5 and the right supporting leg 6 can be adjusted upward and downward. Since the left supporting leg 5 and the right supporting leg 6 are prior art, their specific structures are not described here.

[0063] In the connecting rod assembly of the first embodiment, the end of the left connecting rod 1 away from the first intermediate connecting rod 2 is rotatably connected to the left supporting leg 5, and the end of the right connecting rod 4 away from the second intermediate connecting rod 3 is rotatably connected to the right supporting leg 6. Specifically, a vertical rod segment 140 is provided at the end of the left connecting rod 1 near the left supporting leg 5 and the end of the right connecting rod 4 near the right supporting leg 6. The left connecting rod 1 is rotatably connected to the left supporting leg 5 via its own vertical rod segment 140, and the right connecting rod 4 is rotatably connected to the right supporting leg 6 via its own vertical rod segment 140.

[0064] The bed tube assembly 7 is arranged above the connecting rod assembly and includes a left bed tube bracket 71 and a right bed tube bracket 72. Both the left bed tube bracket 71 and the right bed tube bracket 72 are arranged in a convex shape, which not only has sufficient support range and strength, but also is easy to fold. The left bed tube bracket 71 is arranged on the left support leg 5 and can be rotated up and down, while the right bed tube bracket 72 is arranged on the right support leg 6 and can be rotated up and down. The left bed tube bracket 71 and the right bed tube bracket 72 are rotatably connected. When the bed frame is in the unfolded state, the left bed tube bracket 71 is clamped to the left connecting rod 1. Specifically, the left bed tube bracket 71 is clamped to the first clamp 101 on the first connecting seat 10 of the left connecting rod 1; the right bed tube bracket 72 is clamped to the second clamp 401 on the second connecting seat 40 of the right connecting rod 4, ensuring the structural stability of the bed frame when unfolded and in use. When the bed frame switches from the folded state to the unfolded state, the left bed pipe bracket 71 is disengaged from the first buckle 101 on the left connecting rod 1, and the right bed pipe bracket 72 is disengaged from the second buckle 401 on the right connecting rod 4;

[0065] The upper frame 8 is provided on top of the left supporting leg 5 and the right supporting leg 6. A locking mechanism (not shown) is provided on the upper frame 8. When the locking mechanism is unlocked, the upper frame 8 can be folded along with the folding of the bed frame. The structure of the upper frame 8 is conventional and will not be described in detail here.

[0066] The children's bed frame of this embodiment has an extended state and a folded state. When the bed frame is in the extended state, the bed pipe assembly 7 rests against the connecting rod assembly, which supports and limits the bed pipe assembly 7. When the bed frame switches from the extended state to the folded state, the left and right bed pipe brackets 71 and 72 both rotate upward, and the connecting rod assembly drives the left and right supporting legs 5 and 6 to move synchronously toward the center from the left and right sides. When the bed frame switches from the folded state to the extended state, the connecting rod assembly ensures that the left and right supporting legs 5 and 6 move synchronously away from the center to the left and right sides.

[0067] The folding and unfolding principle of the children's lathe frame of this embodiment is as follows:

[0068] When the child's bed is in normal use, the bed frame is in the unfolded state (such as Figure 9 When the bed frame needs to be folded, the two locking mechanisms on the upper frame 8 are first unlocked, and the middle part of the upper frame 8 can be rotated downward; the bed tube assembly 7 is lifted, so that the left bed tube bracket 71 and the right bed tube bracket 72 are respectively disengaged from the first buckle 101 and the second buckle 401, and rotated upward, driving the left support leg 5 and the right support leg 6 to move toward the middle synchronously, and the connecting rods move toward the middle (as shown in FIG. Figure 10 until it is folded to Figure 11 In the state shown, the folding in the left and right directions is completed, and then the left supporting leg 5 and the right supporting leg 6 are retracted downward to adjust to the lowest state (such as Figure 12 The folding process is the opposite of the folding process.
