Description

Technical Field

[0001] The utility model belongs to the technical field of folding beds, and particularly relates to a folding bed. Background Art

[0002] A camp bed can be used in various places such as indoors, in the courtyard, and in the wild, providing comfort and convenience for people. When the camp bed is used in the wild environment, it separates the human body from the ground to prevent insects from crawling onto the human body; in the event of emergency natural disasters such as earthquakes and mudslides, when houses collapse or are damaged in the disaster, the camp bed is even more an essential tool for resettlement in life.

[0003] For example, Chinese Patent CN218898961U discloses a folding bed, which can remove the legs to adjust the height of the folding bed, but it is not convenient to store the legs after disassembly. Therefore, Chinese Patent CN218588650U discloses a folding bed, which is provided with two slots adapted to the legs on the support. When the legs are inserted into one of the slots, the angle between the legs and the crossbar is an obtuse angle, and the height of the folding bed is relatively high; when the legs are pulled out of one of the slots, the height of the folding bed decreases, and the legs are inserted into the other slot, and the legs are parallel to the crossbar to realize the height adjustment of the folding bed and the storage of the legs. The leg storage steps in the above patents are more, which is not conducive to the convenient use of users. Summary of the Utility Model

[0004] The purpose of the present utility model is to propose a folding bed in view of the above problems existing in the prior art. The technical problem to be solved by the present utility model is: how to facilitate the storage of the legs when adjusting the height of the folding bed.

[0005] The purpose of the present utility model can be achieved by the following technical solutions:

[0006] A folding bed, including a crossbar, with pedestals respectively provided at both ends of the crossbar. A support arm is connected upward on the pedestal, and a bed frame rod and a bed cloth are connected on the support arm. It is characterized in that a support rod is rotatably installed on the pedestal; a limiting structure for restricting the rotation angle of the support rod is provided on the pedestal. The support rod has a first assembly state and a second assembly state. When the support rod is in the first assembly state, the angle between the support rod and the crossbar is an obtuse angle, and the limiting structure restricts the rotation of the support rod, and the support rod supports the crossbar; a fastener adapted to receive the support rod in the second assembly state is provided on the crossbar. When the support rod changes from the first state to the second assembly state, the angle between the support rod and the crossbar decreases until the support rod is received by the fastener.

[0007] The support rod of this folding bed is rotationally connected to the base and the cross bar. When the support rod is in the first assembly state, the support rod is in an open state relative to the cross bar, and the angle between the support rod and the cross bar is an obtuse angle. The limiting structure restricts the rotation of the support rod so that the angle between the support rod and the cross bar can be maintained as an obtuse angle, enabling the support rod to support the cross bar. A fastener is provided on the cross bar, which can receive the support rod and keep the support rod in the second assembly state. The support rod is rotationally connected and can be switched between the first assembly state and the second assembly state, and the support rod is kept in the first assembly state and the second assembly state by the limiting structure and the fastener. Thus, when the user needs to use the folding bed in a state without support feet, the support feet can be switched to the second assembly state and kept in the second state by the fastener, and the user does not need to additionally store the support rod, thereby realizing the convenient storage of the support rod when the height of the folding bed is adjusted.

[0008] In the above folding bed, the limiting structure includes a plug-in part. One end of the support rod is an insertion end, and the insertion end is adapted to be inserted into the plug-in part. A pivot is provided on one of the plug-in part and the insertion end, and a guide groove corresponding to the pivot is provided on the other of the plug-in part and the insertion end. The pivot is slidably matched with the guide groove.

[0009] When the pivot slides to one end of the guide groove, the support rod is in the first assembly state and the support rod is stopped relative to the plug-in part. When the pivot slides to the other end of the guide groove, the support rod can rotate with the plug-in part, and the support rod rotates to the second assembly state.

[0010] In the above folding bed, an avoidance opening is provided on the plug-in part. When the support rod rotates with the plug-in part, the avoidance opening provides an avoidance space for the insertion end to rotate within the insertion part, enabling the support rod to rotate to the second assembly state.

[0011] In the above folding bed, when the support rod is in the first assembly state, the insertion direction of the support rod relative to the plug-in part is consistent with the extension direction of the guide groove.

[0012] In the above folding bed, one end of the guide groove is the first limiting end and the other end is the second limiting end. When the pivot slides to the first limiting end of the guide groove, the support rod is in the first assembly state, the insertion end of the support rod extends into the plug-in part, and the support rod is stopped relative to the plug-in part. When the pivot slides to the second limiting end of the guide groove, the insertion end of the support rod is withdrawn from the plug-in part, and the insertion end can rotate around the pivot within the avoidance space, and the support rod can rotate relative to the plug-in part to the second assembly state.

[0013] In the above folding bed, an elastic member is provided inside the cross bar. Both ends of the elastic member pass through the bases at both ends of the cross bar and extend into the support rods located on the bases at both ends. The end of the elastic member is connected to the support rod. When the support rod is in the second assembly state, the elastic member exerts a pulling force on the support rod in the direction towards the insertion part.

[0014] In the above folding bed, at least two insertion parts are provided on each of the bases. A support platform is also provided on the base between the two insertion parts, and the bottom surface of the support platform is located below the two insertion parts.

[0015] In the above folding bed, when the support rod is in the second assembly state, the support rod is located above the bottom surface of the support platform.

[0016] In the above folding bed, the cross bar is provided with fasteners having the same number as the bases. Each fastener is provided with engaging grooves having the same number as the insertion parts on the base. When the support rod is in the second assembly state, the support rod is located in the engaging grooves.

[0017] In the above folding bed, the opening direction of the engaging groove is the same as that of the avoidance opening on its corresponding side.

[0018] Compared with the prior art, the present folding bed has the following advantages:

[0019] The present folding bed enables the support rod to be maintained in the first assembly state and the second assembly state through the limiting structure and the fasteners. In the second assembly state, the support rod is in the folded state, realizing convenient storage of the legs when adjusting the height of the folding bed.

[0020] The elastic member on the present folding bed can exert a pulling force on the support rod when converting from the second assembly state to the first assembly state, enabling the support rod to automatically return to the first assembly state under the action of the guiding groove and the pivot after disengaging from the fastener.

Detailed implementation mode

[0029] The following are specific embodiments of the present invention and in combination with the attached drawings, the technical solutions of the present invention are further described, but the present invention is not limited to these embodiments.

[0030] Embodiment 1

[0031] As Figure 1 and Figure 2 shown, the folding bed includes at least two bed frame rods 9, and a bed cloth 10 is threaded through the bed frame rods 9. The folding bed further includes a cross bar 1, bases 2 are provided at both ends of the cross bar 1, a support arm 11 is connected upward on the base 2, and the top end of the support arm 11 is clamped with the bed frame rod 9. Two support rods 3 are connected to each base 2, and the support rod 3 is rotatably connected to the base 2. Specifically, the support rod 3 and the base 2 are rotatably connected, and a limit structure for restricting the rotation angle of the support rod 3 is provided on the base 2, so that the support rod 3 can have a first assembly state and a second assembly state after rotation. As Figure 1 shown, when the support rod 3 rotates to the first assembly state, under the action of the limit structure, the support rod 3 can be kept in the first assembly state, the two support rods 3 face downward, and an angle with the opening facing downward is formed between the two support rods 3. In the first assembly state, the support rod 3 supports the cross bar 1, so that the folding bed can be supported on the ground through the support rod 3.

[0032] As Figure 2As shown, when the support rod 3 is switched from the first assembly state to the second assembly state, the support rod 3 rotates, and the angle between the support rod 3 and the cross bar 1 gradually decreases until the support rod 3 rotates to the second assembly state. A fastener 4 is provided on the cross bar 1, and a clamping groove 4a starts to appear on the fastener 4. Further, the number of fasteners 4 on the same cross bar 1 is the same as the number of bases 2, and the number of clamping grooves 4a is set according to the number of support rods 3 on the corresponding base 2. In this embodiment, two bases 2 and two fasteners 4 are provided on each cross bar 1, two support rods 3 are provided on each base 2, and two clamping grooves 4a are correspondingly provided on each fastener 4. When the support rod 3 rotates to be in the second assembly state, the support rod 3 is fixed by the clamping groove 4a of the fastener 4, so that the support rod 3 can be maintained in the second assembly state. A support platform 2c is also provided on the base 2. When the support rod 3 is in the second assembly state, the cross bar 1 is supported by the support platform 2c. Thus, the use height of the folding bed can be adjusted.

[0033] Further, as Figure 3 and Figure 4 shown, the limiting structure includes a plugging portion 2a. The plugging portion 2a is in a cylindrical shape. The support rod 3 has an insertion end 5 that can be inserted into the plugging portion 2a. When the insertion end 5 is located inside the plugging portion 2a, the plugging portion 2a and the insertion end 5 cooperate with each other to limit the rotation of the support rod 3. Further, a pivot 6 is provided on the plugging portion 2a, and a guiding groove 7 adapted to the pivot 6 is provided on the insertion end 5. The cooperation between the pivot 6 and the guiding groove 7 enables the support rod 3 to move along a predetermined trajectory. As Figure 3 shown, when the pivot 6 slides to the first limiting end 7a of the guiding groove 7, the support rod 3 is in the first assembly state, and the support rod 3 is stopped relative to the plugging portion 2a. As Figure 4 shown, when the pivot 6 slides to the second limiting end 7b of the guiding groove 7, the support rod 3 can rotate with the plugging portion 2a, and the support rod 3 rotates to the second assembly state.

[0034] Further, as Figure 4 and Figure 5 shown, when the support rod 3 is in the first assembly state, the insertion direction of the support rod 3 relative to the plugging portion 2a is consistent with the extending direction of the guiding groove 7. An avoidance opening 2b is formed on the plugging portion 2a. When the support rod 3 needs to be switched from the first assembly state to the second assembly state, the support rod 3 is pulled outwards relative to the plugging portion 2a, and the guiding groove 7 is slid from the first limiting end 7a to the second limiting end 7b. The avoidance opening 2b provides an avoidance space for the support rod 3 to rotate inside the insertion portion, so that the support rod 3 rotates to the second assembly state with the pivot 6 as the rotation axis. The formation of the avoidance opening 2b provides a rotation space for the rotation of the support rod 3 on the one hand, and can provide guidance for the rotation of the support rod 3 on the other hand. Further, the opening direction of the avoidance opening 2b on the outer peripheral surface of the plugging portion 2a is perpendicular to the axial direction of the pivot 6. Further, asFigures 2 to 6 As shown, the clamping groove 4a on one side of the fastener 4 has the same opening direction as the avoidance opening 2b on the same side. Specifically, the opening direction of the avoidance opening 2b refers to the opening direction of the avoidance opening 2b on the circumferential surface of the insertion part 2a. At the same time, the clamping base groove also penetrates the bottom surface of the fastener 4.

[0035] Furthermore, as Figure 6 and Figure 7 shown, an elastic member 8 is provided inside the cross bar 1. The two ends of the elastic member 8 respectively pass through the bases 2 at both ends of the cross bar 1 and extend into the support rods 3 located on the bases 2 at both ends. The two ends of the elastic member 8 are respectively connected to the corresponding support rods 3. When the support rod 3 is in the second assembly state, the elastic member 8 is stretched under the action of the support rod 3. The support rod 3 is fixed on the cross bar 1 through the fastener 4, thereby resisting the pulling force of the elastic member 8. When the support rod 3 is separated from the fastener 4, the elastic member 8 exerts a pulling force on the support rod 3 in the direction towards the inside of the insertion part 2a. Under the action of the pivot 6 and the guide groove 7, the support rod 3 rotates inside the insertion part 2a, and the support rod 3 automatically switches from the second assembly state to the first rotation state along a predetermined route. The elastic member 8 can be a rubber band or a tension spring. Preferably, a rubber band is used.

[0036] This folding bed realizes the high and low switching use of the folding bed by rotating the support rod 3 to switch between the first assembly state and the second assembly state and cooperating with the support platform 2c; the fastener 4 on the cross bar 1 can fix the support rod 3 on the cross bar 1 when the support rod 3 is in the second assembly state, which is convenient for users to use and does not require additional storage of the support rod 3; at the same time, under the action of the elastic member 8, the pivot 6 and the guide groove 7, the support rod 3 can be automatically switched from the second assembly state to the first assembly state, which is convenient for users to operate.

[0037] Embodiment 2

[0038] This embodiment is substantially the same as the above embodiment. The difference between this embodiment and the above embodiment is that the pivot 6 in this embodiment is U-shaped, and the two ends of the pivot 6 are connected to the base 2. The limiting structure in this embodiment includes a stop block provided on the base 2. The stop block is located outside the base 2. When the support rod 3 is in the first assembly state, the stop block abuts against the support rod 3 to limit its rotation.
