Description

Technical Field

[0001] The present invention relates to the technical field of folding components, and particularly to a camp bed. Background Art

[0002] As a single-soldier supporting material for the army, the camp bed has the advantages of being foldable, easy to store and release, etc., and can effectively ensure the field camping of officers and soldiers. This bed can also be used for outdoor leisure, hospital escort, home use, etc.

[0003] In the prior art, for example, the Chinese utility model patent publication number CN217117953U discloses a camp bed that is convenient to store and is firm and reliable, including two symmetrically arranged strut assemblies, a fabric for human lying and sleeping laid on the strut assemblies, and a footrest assembly for supporting the strut assemblies and having a folding and unfolding function. The characteristics are as follows: the footrest assembly includes a first footrest rod and a second footrest rod. One end of the first footrest rod is fixed on one of the strut assemblies, and one end of the second footrest rod is fixed on the other strut assembly. The first footrest rod and the second footrest rod are cross-rotationally connected. A limiting component is provided on the second footrest rod, and the first footrest rod can rotate to contact the limiting component and is in a fully unfolded state at this time. However, the volume of this camp bed after folding is still relatively large, and one footrest cooperates with one strut, resulting in poor overall stability. Summary of the Invention

[0004] An object of the present application is to provide a camp bed that has a small volume after folding and good overall stability.

[0005] The technical solution adopted by the present application is: a camp bed, including a fabric and a folding bed frame. The folding bed frame includes a connecting member and two bed rods. At least two pairs of connecting members are provided. Each pair of connecting members is connected by a cross bar. At least two legs and at least one strut are provided on each connecting member. The legs and the strut are rotationally connected to the connecting member. The legs and the strut rotate inward or outward synchronously. The two bed rods are respectively connected to the struts on both sides; the two ends of the fabric are respectively connected to the two bed rods.

[0006] Compared with the prior art, the advantages of the present application are that multiple legs are provided on each connecting member, and the support stability is better and the load-bearing capacity is stronger than that of a single leg, so that the number of connecting members can be reduced and the overall cost can be reduced; the folding mode in which the legs and the strut rotate synchronously makes the volume after folding small and convenient for storage.

[0007] In some embodiments of the present application, the legs and the strut rotate synchronously through a first gear and a second gear that mesh with each other. The first gear and the second gear are both rotationally connected to the connecting member. The legs are connected to the first gear, and the strut is connected to the second gear. The synchronous rotation of the legs and the strut is realized through gear meshing, and the structure is simple and the rotation transmission is reliable.

[0008] Further, both the first gear and the second gear are rotatably connected to the connecting member through a rotating shaft. The rotating shaft is provided with a first plane, and the shaft holes of the first gear and the second gear are provided with a second plane, and the first plane fits with the second plane. The design of the first plane enables the rotating shaft to rotate synchronously with the first gear and the second gear without affecting the rotation of the rotating shaft on the through hole of the connecting member.

[0009] Further, the second gear is provided with a connecting block extending outward, and the support rod is connected to the connecting block; the leg is provided with a connecting hole, the rotating shaft is arranged in the connecting hole, and the connecting hole is provided with a third plane, and the third plane cooperates with the first plane. The connecting block and the second gear are of an integral structure, and the structural strength of the two is high; the support rod is connected to the connecting block, so that the installation position of the support rod is fixed, and the assembly efficiency is improved; the third plane cooperates with the first plane, so that the rotation of the rotating shaft can drive the leg to rotate.

[0010] In some embodiments of the present application, the support rod is provided with a limiting member, and the connecting member is provided with a limiting hole cooperating with the limiting member. The limiting member is used for limiting the rotation of the support rod in the unfolded state of the support rod; the connecting member is provided with an unlocking key for releasing the rotation limit of the support rod, and the unlocking key cooperates with the limiting member. The cooperation of the limiting member and the limiting hole can make the leg and the support rod unfold reliably, and at the same time prevent the leg and the support rod from unfolding beyond the range; the design of the unlocking key can conveniently release the rotation limit of the support rod and improve the use convenience of the user.

[0011] In some embodiments of the present application, the connecting member includes a baffle. In the state where the leg and / or the support rod are unfolded, the leg and / or the support rod are in contact with the baffle. The design of the baffle can prevent the rotation of the support rod from exceeding the range. Since the leg and the support rod rotate synchronously, after the support rod is in contact and restricted from moving, the leg can no longer rotate outward, ensuring the reliable unfolding of the leg and the support rod. At the same time, the baffle can also provide a supporting effect on the support rod. When the limiting member fails, the support rod will also be blocked by the baffle to prevent the support rod from expanding outward and ensuring the safety of the camp bed.

[0012] In some embodiments of the present application, the connecting member includes at least one first installation groove and at least one second installation groove. One end of the leg is located in the first installation groove, and one end of the support rod is located in the second installation groove. The design of the first installation groove and the second installation groove limits the axial movement of the leg and the support rod towards the rotating shaft, ensuring the reliable installation of the leg and the support rod. At the same time, one end of the leg and the support rod are respectively located in the first installation groove and the second installation groove, which can reduce the influence of the outside on the connecting ends of the leg and the support rod and improve the protection of the leg and the support rod; the first gear and the second gear are located in the second installation groove, providing good protection for the gears. The gears are not easily in contact with foreign objects from the outside, which can reduce the influence of the outside on the rotation of the gears and ensure the reliable rotation of the gears.

[0013] Furthermore, two first mounting grooves are provided on the connecting member, one second mounting groove is provided, and two legs are provided on the connecting member. The two legs are respectively located in the two first mounting grooves; the second mounting groove is located between the two first mounting grooves; the first mounting grooves are symmetrically arranged relative to the second mounting groove. The cooperation of the two first mounting grooves and the two legs enables the two legs to be located in different first mounting grooves, so that interference between the two legs will not occur, and at the same time, the distance between the two legs is increased, making the support more stable; the second mounting groove is located in the middle, which also makes the strut located in the middle of the two legs. The force on the strut can be distributed to the two legs, and at the same time, the strut is located exactly in the middle of the two legs, so that the force can be evenly transmitted to the two legs, making the support more stable and firm.

[0014] In some embodiments of the present application, the connecting member is provided with horizontally arranged insertion holes, and both ends of the cross bar are respectively inserted into the two insertion holes of the same pair of connecting members. The design of the insertion holes facilitates the installation of the cross bar. After the cross bar is inserted into the insertion holes, riveting fixation can be carried out, so that the installation angle of the cross bar is uniformly fixed, ensuring the flatness of the camp bed; when the legs and the strut are in the retracted state, the insertion holes are located between the legs and the strut, and the insertion holes can play a role in limiting and blocking, ensuring the reliability of the retraction.

[0015] Furthermore, two insertion holes are provided on each connecting member, and the two insertion holes are respectively located on both sides of the strut; a handle is provided on the side of the connecting member away from the cross bar.

[0016] In some embodiments of the present application, the strut is detachably connected to the bed bar. Description of the Drawings

Detailed implementation manners

[0026] To further elaborate on the technical means and effects adopted by the present invention to achieve the predetermined invention purpose, the following combines the drawings and preferred embodiments to detail the specific implementation manners, structures, features and their effects of the present invention as follows.

[0027] Embodiment 1:

[0028] A folding camp bed provided in this embodiment, as Figure 1 , Figure 2 , Figure 3 shown, includes a fabric 1 and a folding bed frame. The folding bed frame includes a connecting member 2 and two bed rods 3. At least two pairs of the connecting members 2 are provided, and each pair of connecting members 2 is connected by a cross bar 4. At least two legs 5 and at least one support rod 6 are provided on each connecting member 2. The legs 5 and the support rods 6 are both rotatably connected to the connecting member 2, and the legs 5 and the support rods 6 rotate inwards or outwards synchronously. The two bed rods 3 are respectively connected to the support rods 6 on both sides; both ends of the fabric 1 are respectively connected to the two bed rods 3. In this embodiment, the legs 5 face obliquely downwards, and the support rods 6 face obliquely upwards; the rotation directions of the legs 5 and the support rods 6 are opposite; three pairs of the connecting members 2 are provided and are respectively arranged at the front, middle and rear parts of the bed rod 3, so that there is support at the front, middle and rear positions of the folding camp bed.

[0029] Setting multiple legs 5 on each connecting member 2 has better support stability and stronger load-bearing capacity compared to a single leg 5, which can reduce the number of connecting members 2 and lower the overall cost; the folding mode in which the legs 5 and the support rods 6 rotate synchronously results in a small volume after folding, which is convenient for storage.

[0030] To ensure the reliable synchronous rotation of the legs 5 and the support rods 6, as Figure 2As shown, the outrigger 5 and the strut 6 rotate synchronously through the first gear 7 and the second gear 8 that mesh with each other. Both the first gear 7 and the second gear 8 are rotatably connected to the connecting member 2. The outrigger 5 is connected to the first gear 7, and the strut 6 is connected to the second gear 8. The first gear 7 and the second gear 8 mesh with each other, so that the rotation of the first gear 7 or the rotation of the second gear 8 can drive the other gear to rotate synchronously. The outrigger 5 is connected to the first gear 7, and the strut 6 is connected to the second gear 8, so that rotating the outrigger 5 or rotating the strut 6 can drive the other to rotate synchronously through the gears, realizing the synchronous rotation of the outrigger 5 and the strut 6. In this embodiment, the number of teeth and the module of the first gear 7 and the second gear 8 are the same, so that the rotation angles of the outrigger 5 and the strut 6 are the same.

[0031] To ensure the reliable rotation of the first gear 7 and the second gear 8, both the first gear 7 and the second gear 8 are rotatably connected to the connecting member 2 through a rotating shaft 9. The rotating shaft 9 is provided with a first plane 10, and the shaft holes of the first gear 7 and the second gear 8 are provided with a second plane 11, and the first plane 10 fits with the second plane 11. The first plane 10 extends inward from one end of the rotating shaft 9, so that the first gear 7 and the second gear 8 can penetrate from the initial end of the first plane 10 of the rotating shaft 9, ensuring the reliable installation of the first gear 7 and the second gear 8. In this embodiment, both ends of the rotating shaft 9 are provided with threads and are connected to the connecting member 2 through nuts.

[0032] To ensure the reliable rotation of the strut 6, as Figure 4 , Figure 5 shown, the second gear 8 is provided with a connecting block 20 that protrudes outward, and the strut 6 is connected to the connecting block 20; the outrigger 5 is provided with a connecting hole 21, the rotating shaft 9 is inserted through the connecting hole 21, and the connecting hole 21 is provided with a third plane 22, and the third plane 22 cooperates with the first plane 10; the connecting block 20 and the second gear 8 are an integral structure. In this embodiment, the strut 6 is a square tube, the square tube is sleeved on the connecting block 20, and the square tube is riveted and fixed to the connecting block 20. The connection between the strut 6 and the connecting block 20 fixes the installation position of the strut 6, improves the assembly efficiency, and at the same time makes the connection between the strut 6 and the second gear 8 firm, ensuring reliable rotation; the cooperation between the third plane 22 and the first plane 10 enables the rotation of the rotating shaft 9 to drive the outrigger 5 to rotate.

[0033] To ensure the reliable deployment of the strut 6, the strut 6 is provided with a limiting member 12, and the connecting member 2 is provided with a limiting hole 13 that cooperates with the limiting member 12. The limiting member 12 is used to limit the rotation of the strut 6 in the deployed state. In this embodiment, the limiting member 12 adopts a limiting bead. The top of the limiting bead is hemispherical, and a return spring is provided at the bottom of the limiting bead. When the strut 6 is deployed in place, the top of the limiting bead just snaps into the limiting hole 13, so that when the strut 6 continues to move, it will abut against the side of the limiting bead, and the limiting bead plays a role in blocking the movement of the strut 6. Of course, the limiting member 12 can also adopt a V-shaped elastic piece.

[0034] To relieve the limit of the strut 6 and save effort, an unlocking key 14 for relieving the rotational limit of the strut 6 is provided on the connecting member 2, and the unlocking key 14 cooperates with the limiting member 12. In the unfolded state, pressing down the unlocking key 14 can press down the limiting member 12 to relieve the limit of the strut 6. In this embodiment, the unlocking key 14 is a button.

[0035] To ensure the reliable rotational range of the leg 5 and the strut 6, the connecting member 2 includes a baffle 15. In the state where the strut 6 is unfolded, the strut 6 is in contact with the baffle 15. The design of the baffle 15 can prevent the strut 6 from rotating beyond the range. Since the leg 5 and the strut 6 rotate synchronously, after the strut 6 is in contact and restricted from moving, the leg 5 can no longer rotate outwards, ensuring the reliability of the unfolding of the leg 5 and the strut 6. At the same time, the baffle 15 can also provide a supporting effect on the strut 6. When the limiting member 12 fails, the strut 6 will also be blocked by the baffle 15 to prevent the strut 6 from expanding outwards, ensuring the safety of the camp bed. Of course, the baffle 15 can also block the leg 5 alone, or block both the leg 5 and the strut 6 at the same time.

[0036] In this embodiment, the baffle 15 is located on the side opposite to the insertion hole 18, and both the leg 5 and the strut 6 are located between the baffle 15 and the insertion hole 18. When the leg 5 and the strut 6 are opened outwards, they will be limited and blocked by the baffle 15. When the leg 5 and the strut 6 are folded inwards, they will be limited and blocked by the insertion hole 18, ensuring the reliability of unfolding and folding.

[0037] To ensure the reliability of the connecting member 2, the connecting member 2 includes at least one first installation groove 16 and at least one second installation groove 17. One end of the leg 5 close to the connecting member 2 is located in the first installation groove 16, and one end of the strut 6 close to the connecting member 2 is located in the second installation groove 17. The design of the first installation groove 16 limits the axial movement of the leg 5 towards the rotating shaft 9, ensuring the reliable installation of the leg 5. At the same time, one end of the leg 5 is located in the first installation groove 16, which can reduce the influence of the outside world on the connecting end of the leg 5 and improve the protection of the leg 5. The design of the second installation groove 17 limits the axial movement of the strut 6 towards the rotating shaft 9, ensuring the reliable installation of the strut 6. At the same time, one end of the strut 6 is located in the second installation groove 17, which can reduce the influence of the outside world on the connecting end of the strut 6 and improve the protection of the strut 6. The second gear 8 is located in the second installation groove 17, providing good protection for the second gear 8. The second gear 8 is not easily in contact with foreign objects in the outside world, which can reduce the influence of the outside world on the rotation of the second gear 8 and ensure the reliable rotation of the second gear 8. The first gear 7 is located in the second installation groove 17, providing good protection for the first gear 7. The first gear 7 is not easily in contact with foreign objects in the outside world, which can reduce the influence of the outside world on the rotation of the first gear 7 and ensure the reliable rotation of the first gear 7. At the same time, the first gear 7 and the second gear 8 are located in the same installation groove, providing good protection for the meshing transmission.

[0038] To ensure the reliability of the connecting member 2, two first mounting grooves 16 are provided on each connecting member 2, one second mounting groove 17 is provided, two legs 5 are provided on each connecting member 2, and one support rod 6 is provided. The two legs 5 are respectively located in the two first mounting grooves 16; the second mounting groove 17 is located between the two first mounting grooves 16; the first mounting grooves 16 are symmetrically arranged relative to the second mounting groove 17; the legs 5 are symmetrically arranged relative to the second mounting groove 17. Two first mounting grooves 16 are provided to facilitate the two legs 5 being respectively located in one first mounting groove 16, so that the two legs 5 do not affect each other, increasing the distance between the two legs 5 and making the support more stable; the second mounting groove 17 is located in the middle, which also makes the support rod 6 located in the middle of the two legs 5. The force on the support rod 6 can be distributed to the two legs 5. At the same time, the support rod 6 is located exactly in the middle of the two legs 5, enabling the force to be evenly transmitted to the two legs 5, making the support more stable and firm.

[0039] Of course, four first mounting grooves 16 can also be provided. The four first mounting grooves 16 can enable the legs 5 on both sides of each pair of connecting members 2 to be arranged staggeredly, so that the legs 5 on both sides can be staggered from each other after folding.

[0040] To facilitate the connection of the crossbar 4, a horizontally arranged insertion hole 18 is provided on the connecting member 2. The two ends of the crossbar 4 are respectively inserted into the two insertion holes 18 of the same pair of connecting members 2. The design of the insertion hole 18 facilitates the installation of the crossbar 4. After the crossbar 4 is inserted into the insertion hole 18, riveting fixation can be carried out, making the installation angle of the crossbar 4 uniformly fixed and ensuring the flatness of the camp bed. In this embodiment, the insertion hole 18 is located between the two first mounting grooves 16.

[0041] To facilitate storage, the support rod 6 is detachably connected to the bed rod 3. In this embodiment, a card slot 19 is provided on the support rod 6, and the card slot 19 cooperates with the bed rod 3. For installation, only the bed rod 3 needs to be inserted into the card slot 19, and for disassembly, only the bed rod 3 needs to be pulled out of the card slot 19, which is quick and convenient for disassembly and assembly.

[0042] A through hole is provided on the connecting member 2, and the rotating shaft 9 is inserted through the through hole. In the folded state, the support rod 6, the crossbar 4, and the legs 5 are stacked in sequence.

[0043] When folding, press the unlocking key 14 to make the support rod 6 in the unlocked state, and grasp the legs 5 to fold them inward. The legs 5 drive the rotating shaft 9 to rotate, and the rotation of the rotating shaft 9 drives the first gear 7 to rotate, so that the second gear 8 rotates synchronously. The connecting block 20 on the second gear 8 drives the support rod 6 to fold inward to complete the folding;

[0044] Of course, it can also be to grasp the support rod 6 to fold it inward. The support rod 6 drives the second gear 8 to rotate through the connecting block 20, so that the first gear 7 rotates synchronously. The first gear 7 drives the rotating shaft 9 to rotate, and the rotating shaft 9 drives the legs 5 to fold inward to complete the folding.

[0045] When unfolding, grasp the outrigger 5 and unfold it outwards. The outrigger 5 drives the rotation of the rotating shaft 9. The rotation of the rotating shaft 9 drives the rotation of the first gear 7, causing the second gear 8 to rotate synchronously. The connecting block 20 on the second gear 8 drives the support rod 6 to unfold outwards until the limiting member 12 is engaged in the limiting hole 13, completing the unfolding.

[0046] Of course, it is also possible to grasp the support rod 6 and unfold it outwards. The support rod 6 drives the rotation of the second gear 8 through the connecting block 20, causing the first gear 7 to rotate synchronously. The first gear 7 drives the rotation of the rotating shaft 9, and the rotating shaft 9 drives the rotation of the outrigger 5 until the limiting member 12 is engaged in the limiting hole 13, completing the unfolding.

[0047] The cross bar 4 between each pair of connecting members 2 can be either a single bar or two bars. As Figure 6 shown, the design of two cross bars 4 can make the overall structure stronger and the bearing capacity greater.

[0048] Embodiment 2:

[0049] A folding cot provided in this embodiment, as Figure 7 、 Figure 8 shown, in addition to the features described in Embodiment 1, two insertion holes 18 are provided on each connecting member 2, and the two insertion holes 18 are respectively located on both sides of the support rod 6; a handle 23 is provided on the side of the connecting member 2 away from the cross bar 4. The design of the two insertion holes 18 enables each pair of connecting members 2 to be connected by two cross bars 4, with a higher structural strength. The two insertion holes 18 are respectively located on both sides of the support rod 6, and the load-bearing is more balanced; the design of the handle 23 facilitates the carrying of the folding cot.

[0050] The above is only a preferred embodiment of the present invention and does not impose any form of limitation on the present invention. Although the present invention has been disclosed above with a preferred embodiment, it is not intended to limit the present invention. Any person skilled in the art can make some changes or modifications to the above-disclosed technical content to form an equivalent embodiment with equivalent changes, but as long as the technical content of the present invention is not departed from, any brief modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of the present invention still fall within the scope of the technical solution of the present invention.
