DETAILED DESCRIPTION

[0039] The embodiments of the utility model are described in detail below with reference to the accompanying drawings.

[0040] like Figure 1-Figure 13 As shown, a lightweight folding bed comprises a bed surface structure 1 and a plurality of supporting structures 2 which are self-lockingly arranged at the bottom of the bed surface structure 1; the bed surface structure 1 comprises a fabric body 11 and a bed surface tube 12 for supporting the structural strength of the fabric body 11, the supporting structure 2 comprises a transverse tube 3 and a support leg assembly 4 which is hingedly arranged at both ends of the transverse tube 3, and a clamp 43 which is self-locking with the bed surface tube 12 is formed on the top of the support leg assembly 4; the support leg assembly 4 comprises a support tube 41 and a leg tube 42 which are hingedly arranged on the transverse tube 3, and the end of the support tube 41 is hinged to the middle of the leg tube 42, and the end of the transverse tube 3 is hinged with a sliding member 44 for realizing the folding of the support leg assembly 4.

[0041] The leg assembly 4 is rotated to form an open state and a folded state during the articulation process, and the position of the clamp 43 is switched under the action of the open state and the folded state, thereby realizing a detachable connection between the clamp 43 and the bed surface tube 12, and realizing a detachable connection between the bed surface structure 1 and the support structure 2.

[0042] When the leg tube 42 is rotated under force, the support tube 41 hinged to the leg tube 42 causes the sliding member 44 to slide up and down along with the rotation of the leg tube 42 .

[0043] The bed surface tubes 12 are arranged on the opposite sides of the fabric body 11, and the fabric body 11 is fixedly connected to the bed surface tubes 12 by sewing. The clamps 43 of the support leg assemblies 4 at both ends of the cross tube 3 are respectively clamped with the bed surface tubes 12 on both sides of the fabric body 11. Under the action of the two clamps 43, the two bed surface tubes 12 are positioned and clamped at the same time, so that under the positioning and clamping action of the two bed surface tubes 12, support for the fabric body 11 is achieved.

[0044] The clamp 43 is fixedly arranged on the top of the support tube 41, and the opening direction of the clamp 43 is arranged opposite to the tightening direction of the bed surface tube 12 by the fabric body 11. The opening direction of the clamp 43 is arranged outward along the support leg assembly 4. When objects are placed on the fabric body 11 or someone is lying on it, the two bed surface tubes 12 are moved inwardly under the action of gravity, and the bed surface tubes 12 moved inwardly are supported under the action of the clamp 43, thereby realizing the limited abutment between the clamp 43 and the bed surface tube 12.

[0045] The end of the support tube 41 is hinged to the middle of the leg tube 42, and the end of the leg tube 42 is hinged to the middle of the cross tube 3. The support tube 41, the cross tube 3 and the leg tube 42 form a triangular structure when in the open state, so that the whole has better stability.

[0046] The sliding member 44 is sleeved on the support tube 41, and a stopper 45 is formed on the support tube 41 for limiting the sliding position of the sliding member 44. The stopper 45 is used to limit the position of the sliding member 44 to ensure that when the support leg assembly 4 is in an open state, the support tube 41, the cross tube 3 and the leg tube 42 are in a stable triangular structure.

[0047] Embodiment 1: The leg tube 42 includes two parallel foot branch tubes 47, which are hingedly arranged on opposite sides of the cross tube 3, and the support tube 41 is hingedly arranged between the two parallel foot branch tubes 47 of the leg tube 42. The arrangement of the two foot branch tubes 47 strengthens the overall strength of the leg tube 42 and facilitates the stable hinge between the support tube 41 and the leg tube 42.

[0048] A foot sleeve 46 connected to two foot branch tubes 47 is provided at the bottom of the foot tube 42. The bottom of the foot sleeve 46 forms a support seat abutting the ground. The bottom of the support seat is a horizontal structure, thereby increasing the contact area between the foot sleeve 46 and the ground under the action of the support seat, ensuring the support stability of the overall support leg assembly 4.

[0049] Embodiment 2: A supporting leg tube 5 for adjusting the height of the bed surface structure 1 is inserted at the bottom of the leg cover 46, and a plug-in hole 48 corresponding to the supporting leg tube 5 is formed at the bottom of the leg cover 46. The supporting leg tube 5 is in contact with the ground. At this time, the leg cover 46 is in an overhead state, thereby increasing the overall height of the supporting leg assembly 4 and the height of the bed surface structure 1 to meet actual needs.

[0050] The supporting leg tube 5 includes a supporting body 51 and a pin 52 arranged on the top of the supporting body 51. The size of the plug-in hole 48 corresponds to the size of the pin 52. A polyhedral support foot 53 that abuts against the ground is formed at the bottom of the supporting leg tube 5. At this time, the supporting body 51 abuts against the bottom of the foot cover 46 to ensure that the supporting leg tube 5 is stably plugged into the bottom of the foot cover 46. The polyhedral support foot 53 is used to abut against different ground surfaces to ensure the stable setting of the support leg assembly 4.

[0051] The supporting leg tube 5 may also be a columnar structure with the same diameter. The end of the supporting leg tube 5 is inserted into the insertion hole 48 , and the end of the supporting leg tube 5 abuts against the leg cover 46 .

[0052] Embodiment 3: A leg tube adapter 421 hinged to the support tube 41 is provided in the middle of the leg tube 42 , and a transverse tube adapter 422 hinged to the transverse tube 3 is provided at the end of the leg tube 42 . The leg tube adapter 421 and the transverse tube adapter 422 are both fixedly arranged on the leg tube 42 .

[0053] The leg tube adapter 421 is fixedly connected to the leg tube 42 by bolts. When the support leg assembly 4 is in the open state, the relative angle between the leg tube 42 and the support tube 41 changes with the swing of the leg tube 42. When the leg tube 42 swings to a certain angle, the outer wall of the support tube 41 abuts against the leg tube adapter 421, thereby achieving the limiting of the support tube 41 on the leg tube adapter 421, achieving the limiting support between the leg tube 42 and the support tube 41, and achieving support for the open state of the support leg assembly 4 by the abutment between the leg tube adapter 421 and the support tube 41.

[0054] The cross tube adapter 422 is fixedly connected to the leg tube 42 by bolts. When the support leg assembly 4 is in the open state, the relative angle between the leg tube 42 and the support tube 41 changes with the swing of the leg tube 42. When the leg tube 42 swings to a certain angle, the outer wall of the cross tube 3 abuts against the cross tube adapter 422, thereby achieving the limiting of the cross tube 3 on the cross tube adapter 422, and achieving the limiting support between the leg tube 42 and the support tube 41. The cross tube adapter 422 abuts against the cross tube 3 to achieve support for the open state of the support leg assembly 4.

[0055] The leg tube adapter 421 and the cross tube adapter 422 can be arranged separately on the leg tube 42, or they can be arranged on the leg tube 42 at the same time. At the same time, a pin that is plugged into the sliding member 44 can also be arranged on the support tube 41. When the sliding member 44 slides to a certain position on the support tube 41, the sliding member 44 and the support tube 41 are plugged into each other under the action of the pin, thereby supporting the open state of the support leg assembly 4.

[0056] During actual use, the supporting leg tube 5 can be inserted or pulled out to achieve the height switching of the bed surface structure 1. By directly inserting and pulling out the supporting leg tube 5, better strength can be provided, so that when the supporting leg assembly 4 is in the open state, the leg tube 42 can be sufficiently tilted outward, thereby making the entire supporting leg assembly 4 more stable. In addition, the insertion of the supporting leg tube 5 makes the entire leg tube 42 longer, and less force can be used to achieve opening and closing.

[0057] The leg tube 42 can be used as a labor-saving lever for switching the state of the support leg assembly 4, and the purpose of opening or closing can be achieved with less force. When the support leg assembly 4 is to be closed, the foot cover 46 is pressed, so that the foot cover 46 tends to move inward, driving the leg tube 42 to rotate inward around the hinge point with the cross tube 3, driving the support tube 41 to slide downward, so that the distance between the two clips 43 on the same support leg assembly 4 is shortened, so that the clip 43 can be loosened from the bed surface tube 12, and finally the entire product is closed. After closing, the cross tube 3 can be selectively plugged in and out according to actual needs.

[0058] When opening, the operation is reversed, and the foot cover 46 is supported outward, driving the foot tube 42 to rotate outward around the hinge point with the horizontal tube 3, driving the support tube 41 to slide upward, so that the final sliding member 44 contacts the stopper 45, and after reaching the predetermined position, the foot cover 46 is in the open state. In this state, due to the tension of the fabric body 11, the two clamps 43 on the same leg assembly 4 tend to approach each other, thereby forcing the final sliding member 44 and the clamp 43 to tend to move away from each other, but the stopper 45 plays a limiting role, so that the fabric body 11 can continue to remain tight.

[0059] At the same time, the leg tube 42 is arranged obliquely outward. When a person lies on the fabric body 11, the leg tube 42 has a tendency to rotate outward, thereby driving the support tube 41 to have a tendency to poke upward relative to the sliding member 44, and the stopper 45 plays a blocking role, so that the leg tube 42 maintains its original state. Since the stopper 45 plays a limiting role, when the support leg assembly 4 reaches the open state, the entire support leg assembly 4 is very stable, the fabric body 11 can be very tight, and when a person lies on it, there will be a tendency to be tighter.

[0060] The above description of the disclosed embodiments enables those skilled in the art to implement or use the present invention. Various modifications to these embodiments will be apparent to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the present invention; therefore, the present invention will not be limited to the embodiments shown herein, but will conform to the widest scope consistent with the principles and novel features disclosed herein.

[0061] Although the following terms are used more frequently in this article: bed surface structure 1, fabric body 11, bed surface tube 12, support structure 2, transverse tube 3, support leg assembly 4, support tube 41, leg tube 42, leg tube adapter 421, transverse tube adapter 422, clamp 43, sliding member 44, stopper 45, leg cover 46, leg branch tube 47, plug hole 48, support leg tube 5, support body 51, latch 52, polyhedral support leg 53, etc., the possibility of using other terms is not excluded. These terms are used only to more conveniently describe and explain the essence of the utility model; interpreting them as any additional restrictions is contrary to the spirit of the utility model.
