Description

Technical Field

[0001] This utility model relates to the technical field of cots, and in particular to a cot support structure that can be quickly unfolded and retracted. Background Technology

[0002] Camp beds are foldable beds used by troops during marches. They are made of metal frames and canvas, and their small size when folded and bagged makes them easy to carry. They are also commonly used for outdoor work and are a relatively common outdoor tool.

[0003] Most existing cot frames are fixed-disassembly structures, consisting of support legs and latches bolted to the frame. When assembling the cot, each support leg must be individually bolted to the frame, the latches secured to the rods on the cot surface, and then bolted again to lock them in place. This assembly process is inefficient, significantly impacting the speed of cot assembly and folding. Furthermore, each individual support leg and latch needs to be stored separately, resulting in poor portability and indicating room for improvement. Utility Model Content

[0004] The purpose of this utility model is to provide a quick-expanding and retractable cot support structure to solve the problem mentioned in the background art that most existing cot supports use bolt structures to assemble the support legs and claw structures, which not only affects the assembly and retraction efficiency of the cot, but also requires separate storage of multiple support legs and claw structures after disassembly, reducing the portability of the cot.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a cot support structure for quick deployment and folding, comprising a cot assembly and a support assembly. The cot assembly includes a cot body, on the left side of which two circular grooves are provided, and aluminum rods are provided on the inner walls of the circular grooves. Several snap-fit ​​holes are provided on the lower surface of the cot body at positions corresponding to the circular grooves. The bracket assembly includes two sets of support rods, each set of support rods having several limiting holes on its upper surface. The opposite ends of the two sets of support rods are provided with telescopic mechanisms, and the ends of the two sets of support rods away from the telescopic mechanisms are provided with bracket mechanisms. The bracket mechanisms include integrated brackets, and the ends of the two sets of support rods away from the telescopic mechanisms are respectively fixedly connected to two integrated brackets.

[0006] Preferably, the telescopic mechanism includes a telescopic frame with left and right openings, and two limiting grooves are provided on the inner top wall and inner bottom wall of the telescopic frame.

[0007] Preferably, four locking bolts are threadedly connected to the upper surface of the telescopic frame at positions corresponding to the two limiting grooves, and limiting blocks are fixedly connected to the upper and lower surfaces of the two sets of support rods.

[0008] Preferably, the limiting block is slidably connected to the inner wall of the limiting groove, the locking bolt is adapted to the limiting hole, the support rod can slide in the limiting groove in the telescopic frame through the limiting block, and the position of the support rod in the telescopic frame can be locked by the locking bolt and the limiting hole. In addition, due to the limiting effect of the limiting block and the limiting groove, the two sets of support rods will not detach from the telescopic frame.

[0009] Preferably, the surface of the integrated bracket is fixedly connected to two semi-circular frames, and the surface of the integrated bracket is fixedly connected to two angled cylinders. The inner walls of the two angled cylinders are fixedly connected to elastic ropes. The end of the elastic rope away from the angled cylinder is fixedly connected to a support leg, and the support leg is adapted to the semi-circular frames. The inner wall of the integrated bracket is fixedly connected to a rotating shaft, so that the support leg can be taken out from the angled cylinder. After being taken out, it is connected by the elastic rope and will not detach from the angled cylinder. At this time, the support leg can be locked in the semi-circular frames and does not need to be stored separately.

[0010] Preferably, a circular rod is rotatably connected to the surface of the rotating shaft. Two slots are formed on the surface of the circular rod. A positioning shaft is fixedly connected to the surface of the circular rod. A snap-fit ​​frame is rotatably connected to both ends of the positioning shaft. Through holes are formed on both the front and back of the snap-fit ​​frame. An arc-shaped claw is fixedly connected to the end of the snap-fit ​​frame. The arc-shaped claw is adapted to the aluminum rod. The rotating shaft allows the circular rod to rotate on the integrated bracket. When the cot needs to be unfolded and supported, the circular rod rotates to the side position of the integrated bracket. When the cot needs to be dismantled, the circular rod rotates to the bottom position of the integrated bracket.

[0011] Preferably, the front and back of the snap-fit ​​frame are fixedly connected to a clamping frame, the inner wall of the clamping frame is rotatably connected to a damping shaft, the surface of the damping shaft is fixedly connected to a pressing block, and the opposite surfaces of the two pressing blocks are fixedly connected to a locking block, which is adapted to the through hole and the locking slot respectively.

[0012] Compared with the prior art, the beneficial effects of this utility model are: 1. This type of quick-expanding and retractable cot support structure, through the design of the support mechanism, utilizes the semi-circular locking frame and elastic rope to avoid separating the support legs for storage. Instead, the legs are directly locked into the semi-circular locking frame, forming an integral whole with the support mechanism. This makes assembly faster. At the same time, the locking frame and arc-shaped claws can also rotate to the bottom position of the integrated support through the cooperation of the rotating shaft and circular rod. This prevents the locking frame from separating from the integrated support, avoiding the need to store these structures separately. Instead, it forms a whole structure that can rotate and change volume, further improving the efficiency of the cot in unfolding and retracting.

[0013] 2. This quick-expanding and retractable cot support structure, through the setting of the telescopic mechanism, allows the two sets of support rods to move left and right within the telescopic frame during use, using the cooperation of the limiting groove and the limiting block. At the same time, the four locking bolts on the top of the telescopic frame can lock the position of the support rods within the telescopic frame. Therefore, after unfolding, it can be used for cot bodies of different sizes. After the support rods retract into the telescopic frame, the volume of the support assembly is further reduced, improving the overall portability of the cot. Attached Figure Description

[0016] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.

[0017] Please see Figure 1-8 This utility model provides a technical solution: Example 1: A quick-expanding and retractable cot support structure, including a cot assembly 1 and a support assembly 2. The cot assembly 1 includes a cot body 101. Two circular grooves are opened on the left side of the cot body 101. An aluminum rod 102 is provided on the inner wall of the circular grooves. Several snap-fit ​​holes 103 are opened on the lower surface of the cot body 101 at positions corresponding to the circular grooves. The bracket assembly 2 includes two sets of support rods 21. Each set of support rods 21 has several limiting holes on its upper surface. The opposite ends of the two sets of support rods 21 are provided with telescopic mechanisms 22. The ends of the two sets of support rods 21 away from the telescopic mechanisms 22 are provided with bracket mechanisms 23. The bracket mechanisms 23 include integrated brackets 2301. The ends of the two sets of support rods 21 away from the telescopic mechanisms 22 are respectively fixedly connected to the two integrated brackets 2301.

[0018] Furthermore, the telescopic mechanism 22 includes a telescopic frame 2201, which has a left and right open structure. The inner top wall and inner bottom wall of the telescopic frame 2201 are provided with two limiting grooves 2202. The upper surface of the telescopic frame 2201 is threaded with four locking bolts 2203 at positions corresponding to the two limiting grooves 2202. The upper and lower surfaces of the two sets of support rods 21 are fixedly connected with limiting blocks 2204. The limiting blocks 2204 are slidably connected to the inner wall of the limiting grooves 2202. The locking bolts 2203 are adapted to the limiting holes. After the locking bolts 2203 are unscrewed, the two sets of support rods 21 are no longer restricted within the telescopic frame 2201 and can slide within the limiting groove 2202 via the limiting block 2204, thus facilitating the unfolding or retraction of the support rods 21. When unfolded, they can support the cot, and when retracted, they can significantly reduce the volume of the overall support assembly 2, making it easy to store and carry.

[0019] Furthermore, two semi-circular frames 2302 are fixedly connected to the surface of the integrated bracket 2301, and two angled cylinders 2303 are fixedly connected to the surface of the integrated bracket 2301. Elastic ropes 2304 are fixedly connected to the inner walls of the two angled cylinders 2303. A support leg 2305 is fixedly connected to the end of the elastic rope 2304 away from the angled cylinder 2303, and the support leg 2305 is adapted to the semi-circular frames 2302. Two angled cylinders 2303 can support the support legs 2305. By cooperating with multiple sets of angled cylinders 2303 and support legs 2305, the entire cot can be supported. In addition, the support legs 2305 are fixed to the inner wall of the angled cylinders 2303 by elastic ropes 2304. Therefore, the support legs 2305 will not fall off after being taken out of the angled cylinders 2303. At this time, the support legs 2305 can be locked in the semi-circular frame 2302 to avoid separate storage and make assembly faster. Furthermore, a rotating shaft 2306 is fixedly connected to the inner wall of the integrated bracket 2301. A circular rod 2307 is rotatably connected to the surface of the rotating shaft 2306. Two slots are opened on the surface of the circular rod 2307. A positioning shaft 2308 is fixedly connected to the surface of the circular rod 2307. A snap-fit ​​frame 2309 is rotatably connected to both ends of the positioning shaft 2308. Through holes are opened on the front and back of the snap-fit ​​frame 2309. An arc-shaped claw 2310 is fixedly connected to the end of the snap-fit ​​frame 2309. The arc-shaped claw 2310 is adapted to the aluminum rod 102. The rotating shaft 2306 allows the circular rod 2307 to rotate within the integrated bracket 2301. After the circular rod 2307 rotates to the bottom of the integrated bracket 2301, the snap-fit ​​frame 2309 can be rotated to the same direction as the integrated bracket 2301 without removing it. This reduces the overall volume of the integrated bracket 2301, improves the efficiency of unfolding and assembly, and makes it easier to carry and store. Furthermore, clamping frames 2311 are fixedly connected to both the front and back of the snap-fit ​​frame 2309. A damping shaft 2312 is rotatably connected to the inner wall of the clamping frame 2311. A pressing block 2313 is fixedly connected to the surface of the damping shaft 2312. A locking block 2314 is fixedly connected to the opposite surfaces of the two pressing blocks 2313. The locking blocks 2314 are respectively adapted to the through hole and the slot. The pressing block 2313 can drive the damping shaft 2312 to rotate. At this time, the two pressing blocks 2313 can drive the two locking blocks 2314 to disengage from the locking groove on the surface of the circular rod 2307 and disengage from the through hole. At this time, the locking frame 2309 and the circular rod 2307 are no longer restricted. The locking frame 2309 can rotate relative to the circular rod 2307 around the positioning shaft 2308, so that the arc-shaped claw 2310 loses the squeezing force on the aluminum rod 102, which facilitates the quick clamping and disengagement of the aluminum rod 102.

[0020] Working principle: When the cot is needed, first insert the two aluminum rods 102 into the two circular slots of the cot body 101. At this time, the two aluminum rods 102 can support the cot body 101. At the same time, pull out the four locking bolts 2203 and pull the two sets of support rods 21 to their extreme positions. Due to the restriction of the limit block 2204, the two sets of support rods 21 will not disengage from the telescopic frame 2201. Then, use the four locking bolts 2203 to lock the position of the two sets of support rods 21, and remove the support legs 2305 from the semi-circular frame 2302. Insert the angled cylinder 2303, then use the rotating shaft 2306 to open the circular rod 2307, press down the two pressing blocks 2313 to move the two locking blocks 2314 away from each other. At this time, rotate the locking frame 2309 to the through hole position through the positioning shaft 2308. After releasing the two pressing blocks 2313, the reaction force of the damping rotating shaft 2312 drives the two locking blocks 2314 to pass through the through hole and enter the two locking slots on the surface of the circular rod 2307, thereby locking the position of the locking frame 2309 and the circular rod 2307. At this time, the two arc-shaped claws 23 10. The two aluminum rods 102 are secured to the surface of the locking holes 103, completing the assembly of the entire cot. During storage, the locking block 2314 is disengaged from the slot by pressing the block 2313, the damping shaft 2312, and the locking block 2314. At this time, the locking frame 2309 can rotate relative to the circular rod 2307 around the positioning shaft 2308, causing the two arc-shaped locking claws 2310 to disengage from the surface of the aluminum rods 102. Then, the circular rod 2307 is rotated to the bottom of the integrated bracket 2301 via the rotating shaft 2306, simultaneously securing the two supports... Leg 2305 is removed from the angled cylinder 2303. Due to the connection of the elastic rope 2304, the support leg 2305 will not fall off. At this time, the support leg 2305 is locked in the semi-circular frame 2302, so that the integrated bracket 2301 can form a whole without any disassembly of the structure, which improves the disassembly efficiency. At the same time, after the four locking bolts 2203 are removed, the two sets of support rods 21 can be retracted into the telescopic frame 2201 through the limiting block 2204, thereby reducing the overall volume of the bracket assembly 2 and further improving the storage and portability of the bracket assembly 2.
