Description

Technical Field

[0001] This utility model relates to the technical field of infant bathing products, and in particular to a retractable and collapsible folding bathtub support mechanism and a folding bathtub. Background Technology

[0002] In modern childcare, baby bathtubs are an essential baby care product for every family, and folding bathtubs are favored by many parents because of their advantages such as saving space and being easy to carry.

[0003] Most current baby folding bathtubs have a fixed length and cannot be adapted to different baby sizes, making it difficult for babies to maintain a comfortable and stable posture during bathing. When babies are small, bathing in a large tub can cause them to roll or slide in the water if parents don't hold them properly, leading to water entering their ears and mouths, causing ear infections or other health problems. As babies grow older and the tub space becomes insufficient, they may struggle or move around due to their limited space, increasing the risk of the tub tipping over or the baby slipping out. Fixed-length baby folding bathtubs can only be used during specific stages of a baby's growth. As the baby grows beyond the tub's suitable size, parents need to replace it with a larger one, undoubtedly increasing childcare costs. Utility Model Content

[0033] Most existing folding baby bathtubs have a fixed length, making it difficult to adapt to the changing body size of infants as they grow, causing many problems in the childcare process. When infants are young, a bathtub that is too large can cause them to slide in the water, increasing the risk of water entering their ears and mouths and causing health problems. As infants grow, the bathtub may not have enough space, causing them to struggle due to their limited size, increasing the safety risks of the bathtub tipping over or the infant slipping. Furthermore, the fixed length design means that the bathtub can only be used at a specific stage, and frequent replacements undoubtedly increase the family's childcare costs. At the same time, even when folded, it may still take up a lot of space for storage. These problems urgently need to be solved.

[0034] To enable the support mechanism to flexibly adjust its length as the baby grows to fit different body shapes, and to be easily folded to save storage space, thereby improving the safety, comfort, and economy of bathtub use, this utility model proposes a retractable and foldable bathtub support mechanism.

[0035] Please see Figures 1-2In one embodiment of the present invention, the retractable folding bathtub support mechanism includes a first frame 100 and a second frame 300.

[0036] The first frame 100 has a first length adjustment component 200 at one end; the second frame 300 has a second length adjustment component 400 at the end opposite to the first length adjustment component 200. The first length adjustment component 200 and the second length adjustment component 400 are hinged together.

[0037] In this embodiment, a first length adjustment component 200 is provided at one end of the first frame 100, and a second length adjustment component 400 is provided at the opposite end of the second frame 300. These two adjustment components are connected by a hinge, forming a dual-function structure that allows for adjustable length and foldable storage. In actual use, parents can operate the first length adjustment component 200 and the second length adjustment component 400 to change the relative position of the first frame 100 and the second frame 300, thereby adjusting the length of the entire support mechanism. For example, when the baby is small, the relative distance between the two frames can be shortened to allow the bathtub's internal space to fit the baby's size and prevent the baby from sliding; as the baby grows, the distance between the two frames can be increased to provide sufficient space for the baby to move and maintain a comfortable and stable bathing posture.

[0038] When storing, since the first length adjustment component 200 and the second length adjustment component 400 are connected by hinges, the two frames can be rotated slightly to fold and close together around the hinge point, which can greatly reduce the overall volume of the support mechanism, making it convenient for parents to store it in a corner of the bathroom or in a storage space, reducing the space occupied in the home.

[0039] The technical solution of this utility model involves providing a first length adjustment component 200 at one end of the first frame 100, and a second length adjustment component 400 at the opposite end of the second frame 300, with the first length adjustment component 200 and the second length adjustment component 400 connected by a hinge. The relative position of the two frames is adjusted by operating the first length adjustment component 200 and the second length adjustment component 400, thereby adjusting the length of the support mechanism. Furthermore, the hinged connection between the first length adjustment component 200 and the second length adjustment component 400 allows the first frame 100 and the second frame to be folded for easy storage.

[0040] See Figures 3-6 In one embodiment, the first length adjustment component 200 includes: The first sleeve 210 has a first channel 211. The end of the first frame 100 is slidably connected to the first channel 211. The first sleeve 210 has a first side wall 212. The first side wall 212 has a first groove 213. The first groove 213 communicates with the first channel 211. The first groove 213 and the first side wall 212 form a first snap-fit ​​part 214. The first locking member 220 is disposed in the first groove 213 and connected to the end of the first frame 100. The first locking member 220 has a first sliding groove 221 on its side wall. The first sliding groove 221 is slidably connected to the first snap-fit ​​part 214. One end of the first locking member 220 has a first elastic arm 222. The first snap-fit ​​part 214 has at least one first limiting groove 215. The first elastic arm 222 has a first limiting protrusion 223, which is used to snap-fit ​​with the first limiting groove 215.

[0041] In this embodiment, the first length adjustment assembly 200 achieves length adjustment and locking through the sliding engagement of the sleeve and the locking member. The first sleeve 210 serves as the basic carrier for adjustment and has a first channel 211 inside for the end of the first frame 100 to move. The end of the first frame 100 can slide freely along the first channel 211, providing basic movement space for length changes. A first groove 213 communicating with the first channel 211 is formed on the first sidewall 212 of the first sleeve 210. The groove and the sidewall together form a first engaging portion 214, which not only reserves a position for the installation of the locking member but also provides a guiding structure for the sliding process.

[0042] The first locking member 220 is installed in the first groove 213 and connected to the end of the first frame 100, moving synchronously with the first frame 100. The first sliding groove 221 on its side wall forms a sliding fit with the first engaging portion 214. When the first frame 100 slides along the first channel 211, the first locking member 220 moves smoothly along the first engaging portion 214 via the first sliding groove 221, ensuring smooth adjustment. To achieve stable positioning after adjustment, one end of the first locking member 220 extends into a first elastic arm 222. At least one first limiting groove 215 is provided on the first engaging portion 214, and the first limiting protrusion 223 on the elastic arm can engage and fix with the limiting groove.

[0043] In actual adjustment, if it is necessary to change the relative length between the first frame 100 and the first sleeve 210, pressing and pushing the first locking member 220 can deform the first elastic arm 222, causing the first limiting protrusion 223 to disengage from the current first limiting groove 215. At this time, pushing or pulling the first frame 100 causes the first locking member 220 to slide the first frame 100 along the first channel 211 and the first locking part 214. Once the desired length is reached, the first elastic arm 222 is released, and the elastic arm resets under its own elastic force. The first limiting protrusion 223 then engages with the corresponding first limiting groove 215, completing the length locking. This structure achieves rapid adjustment and stable locking through the deformation and reset of the elastic arm. It is easy to operate and reliably positioned, ensuring the support mechanism remains stable at different lengths and providing safe and reliable support for the baby bathing process.

[0044] See Figures 6 to 8 as well as Figures 11-12 In one embodiment, the second length adjustment component 400 includes: The second sleeve 410 has a second channel 411. The end of the second frame 300 is slidably connected to the second channel 411. The second sleeve 410 has a second side wall 412. The second side wall 412 has a second groove 413. The second groove 413 communicates with the second channel 411. The second groove 413 and the second side wall 412 form a second snap-fit ​​part 414. The second locking member 420 is disposed in the second groove 413 and connected to the end of the second frame 300. The side wall of the second locking member 420 is provided with a second sliding groove 421, which is slidably connected to the second snap-fit ​​part 414. One end of the second locking member 420 is provided with a second elastic arm 422. The second snap-fit ​​part 414 is provided with at least one second limiting groove 415. The second elastic arm 422 is provided with a second limiting protrusion 423, which is used to snap-fit ​​with the second limiting groove 415.

[0045] In this embodiment, the second length adjustment assembly 400 adopts a structural design similar to that of the first length adjustment assembly 200. Length adjustment and secure locking are achieved through the coordinated cooperation of the second sleeve 410 and the second locking member 420, ensuring synchronous adaptation of the two frames during adjustment. The second sleeve 410, as the basic structure of the assembly, has a second channel 411 inside for the movement of the end of the second frame 300. The end of the second frame 300 can slide freely along the second channel 411, providing basic movement space for length changes. A second groove 413 communicating with the second channel 411 is formed on the second sidewall 412 of the second sleeve 410. This groove, together with the sidewall, forms a second engaging portion 414, providing both accommodating space for the installation of the locking member and precise guidance during the sliding process.

[0046] The second locking member 420 is installed in the second groove 413 and fixedly connected to the end of the second frame 300, moving synchronously with the second frame 300. The second sliding groove 421 on its side wall forms a sliding fit with the second engaging portion 414. When the second frame 300 slides along the second channel 411, the second locking member 420 moves smoothly along the second engaging portion 414 via the second sliding groove 421, ensuring smooth adjustment. To achieve stable positioning after adjustment, a second elastic arm 422 extends from one end of the second locking member 420. At least one second limiting groove 415 is correspondingly provided on the second engaging portion 414, and the second limiting protrusion 423 on the elastic arm can engage and fix with these grooves.

[0047] In actual operation, when adjusting the relative length of the second frame 300 and the second sleeve 410, pressing and pushing the second locking member 420 can deform the second elastic arm 422, causing the second limiting protrusion 423 to disengage from the current second limiting groove 415. At this time, pushing or pulling the second locking member 420 causes the second frame 300 to slide along the second channel 411 and the second locking part 414. Once the desired length is reached, releasing the second locking member 420 allows the second elastic arm 422 to reset under its own elastic force, and the second limiting protrusion 423 engages with the corresponding second limiting groove 415, completing the length locking. This structural design allows the second length adjustment component 400 and the first length adjustment component 200 to cooperate, achieving flexible adjustment of the overall length of the support mechanism through their respective adjustment functions. The hinged connection between the two ensures both spatial adaptability for infants of different sizes and structural stability after adjustment, further enhancing the practicality and safety of the support mechanism.

[0048] See Figures 3-6 In one embodiment, the first snap-fit ​​portion 214 has a first protruding edge 216 along its edge, and the first limiting groove 215 is disposed on the first protruding edge 216.

[0049] See Figures 6 to 8 ,as well as Figures 11-12 In one embodiment, the edge of the second snap-fit ​​portion 414 is provided with a second protruding edge 416, and the second limiting groove 415 is disposed on the second protruding edge 416.

[0050] See Figures 3-6 In one embodiment, the first locking member 220 includes a first mounting portion 224, which is connected to the end of the first frame 100. The first mounting portion 224 is provided with a first protrusion 225, and the first protrusion 225 is provided with a first pressing portion 226. The first pressing portion 226, the side wall of the first protrusion 225 in the length direction, and the first mounting portion 224 form a first sliding groove 221. The first elastic arm 222 is disposed on the side wall of the first protrusion 225.

[0051] In this embodiment, a stable connection with the first frame 100 is achieved through the first mounting part 224. As the core component connecting the locking member and the frame, the first mounting part 224 is directly and fixedly connected to the end of the first frame 100. This connection method ensures that the frame can move synchronously with the locking member. The first mounting portion 224 has a first protrusion 225 integrally formed on it. The protrusion provides a carrier for the subsequent pressing structure and the sliding groove, and also enhances the overall structural strength of the locking component. The first protrusion 225 has a first pressing portion 226 for easy operation by parents. This pressing portion protrudes from the surface of the protrusion, allowing parents to apply force more easily during adjustment. It should be noted that the first pressing portion 226, the sidewalls of the first protrusion 225 along their length direction, and the first mounting portion 224 together form a first sliding groove 221. This sliding groove structure forms a sliding fit with the first engaging portion 214. When the locking component moves, the first sliding groove 221 slides smoothly along the engaging portion, effectively reducing the feeling of jamming during adjustment. The first elastic arm 222 is disposed on the side wall of the first protrusion 225 and is integrally formed with the protrusion. This arrangement allows for a more reasonable deformation space for the elastic arm. When a parent presses the first pressing part 226, the force can be transmitted through the first protrusion 225 to the first elastic arm 222, causing the first elastic arm 222 to deform and drive the first limiting protrusion 223 to disengage from the first limiting groove 215. When the first pressing part 226 is released, the first elastic arm 222 can quickly return to its original position using its own elasticity, ensuring that the limiting protrusion accurately engages with the corresponding groove.

[0052] See Figures 6 to 8 as well as Figures 11-12In one embodiment, the second locking member 420 includes a second mounting portion 424, which is connected to the end of the second frame 300. The second mounting portion 424 is provided with a second protrusion 425, and the second protrusion 425 is provided with a third pressing portion 426. A second sliding groove 421 is formed between the third pressing portion 426, the side wall of the second protrusion 425 in the length direction, and the second mounting portion. The second elastic arm 422 is disposed on the side wall of the second protrusion 425.

[0053] In this embodiment, a second protrusion 425 is integrally formed on the second mounting part 424. The protrusion not only provides a solid support for the subsequent formation of the pressing structure and the sliding groove, but also enhances the overall structural strength of the second locking member 420, making it less prone to deformation during long-term use. A third pressing part 426 is provided on the second protrusion 425 for easy operation by parents. This pressing part protrudes from the surface of the second protrusion 425, allowing parents to apply force more easily during adjustment and improving the ease of operation. It should be noted that the third pressing part 426, the sidewall of the second protrusion 425 along its length, and the second mounting part 424 together form a second sliding groove 421. This sliding groove structure forms a sliding fit with the second locking part 414. When the second locking member 420 moves, the second sliding groove 421 slides smoothly along the second locking part 414, making length adjustment smoother. The second elastic arm 422 is disposed on the side wall of the second protrusion 425 and is integrally formed with the second protrusion 425. When the parent presses and pushes the third pressing part 426, the force can be transmitted to the second elastic arm 422 through the second protrusion 425, causing the second elastic arm 422 to deform and drive the second limiting protrusion 423 to disengage from the second limiting groove 415. When the third pressing part 426 is released, the second elastic arm 422 can quickly return to its original position with its own elasticity, ensuring that the second limiting protrusion 423 is accurately engaged in the corresponding groove, thereby achieving a stable locking of the relative length between the second frame 300 and the second sleeve 410.

[0054] See Figures 3-6 In one embodiment, a second pressing part 227 is further included. One end of the second pressing part 227 is provided with a first clamping part 228 and a second clamping part 229 at a distance.

[0056] In one embodiment, the first length adjustment assembly 200 includes a first connector 230, a first mounting hole 2241 is provided on the first mounting part 224, and a second mounting hole 110 is provided on the end of the first frame 100. The first mounting part 224 is detachably connected to the end of the first frame 100 by means of the first connector 230 passing through the first mounting hole 2241 and being threadedly connected to the second mounting hole 110.

[0057] In this embodiment, the first connecting member 230 enables a detachable connection between the first mounting part 224 and the end of the first frame 100, further improving the assembly flexibility and maintenance convenience of the structure. The first mounting part 224 has a first mounting hole 2241 for the connecting member to pass through, and the corresponding end of the first frame 100 has a second mounting hole 110. The diameters of the two mounting holes are adapted to the size of the first connecting member 230, providing a corresponding mating structure for the threaded connection. During assembly, the first connector 230 is passed through the first mounting hole 2241 of the first mounting part 224 and then threadedly connected to the second mounting hole 110 at the end of the first frame 100. The two are firmly fixed by the interlocking action of the threads.

[0058] See Figures 6 to 8 as well as Figures 11-12 In one embodiment, the second length adjustment assembly 400 includes a second connector 430, a third mounting hole 4241 is provided on the second mounting part 424, and a fourth mounting hole 310 is provided on the end of the second frame. The second mounting part 424 is detachably connected to the end of the second frame 300 by means of the second connector 430 passing through the third mounting hole 4241 and being threadedly connected to the fourth mounting hole 310.

[0059] In this embodiment, similarly, the second length adjustment assembly 400 achieves a detachable connection between the second mounting part 424 and the end of the second frame 300 via the second connector 430, further enhancing the assembly flexibility and maintenance convenience of the structure. The second mounting part 424 has a third mounting hole 4241 for the second connector 430 to pass through, and the end of the second frame 300 has a corresponding fourth mounting hole 310. The diameters of the two mounting holes are adapted to the dimensions of the second connector 430, providing a corresponding mating structure for the threaded connection and ensuring the stability of the connection. During assembly, the second connector 430 is passed through the third mounting hole 4241 of the second mounting part 424 and then threadedly connected to the fourth mounting hole 310 at the end of the second frame 300. The two are firmly fixed by means of the tight engagement between the threads.

[0060] See Figures 1 to 8In one embodiment, it further includes a first rotating shaft 500, and a first connecting portion 120 is provided on one end of the first length adjusting component 200 opposite to the second length adjusting component 400. The first connecting portion 120 is provided with a first through hole 121. The second length adjustment component has a second connecting part 320 on one end opposite to the first length adjustment component 200. The second connecting part 320 has a first mounting position 321 and a second through hole 322. The first connecting part 120 is at least partially inserted into the first mounting position 321. The first rotating shaft 500 passes through the first through hole 121 and the second through hole 322. The first length adjustment component 200 is hinged to the second length adjustment component 400 through the first rotating shaft 500.

[0061] In this embodiment, the first length adjustment component 200 and the second length adjustment component 400 are hinged together via a first pivot 500, enabling the bathtub to be folded and retracted. A first connecting portion 120 is provided at one end of each of the first and second length adjustment components 200 and 400, and a first through hole 121 is provided on this connecting portion for the pivot to pass through. The diameter of the through hole is matched with the diameter of the first pivot 500, ensuring that the pivot can pass through smoothly and the connection is secure. See Figures 11-12 The second length adjusting component 400 has a second connecting portion 320 at one end opposite to the first length adjusting component 200. The second connecting portion 320 has not only a second through hole 322 corresponding to the first through hole 121, but also a first mounting position 321 for accommodating the first connecting portion 120. During assembly, the first connecting portion 120 is at least partially inserted into the first mounting position 321, ensuring that the axes of the first through hole 121 and the second through hole 322 coincide. Then, the first rotating shaft 500 is sequentially inserted through the first through hole 121 and the second through hole 322, achieving hinged connection between the two through the tight fit between the rotating shaft and the through hole.

[0062] When the bathtub needs to be folded, the first length adjustment component 200 and the second length adjustment component 400 can rotate relative to each other around the first pivot 500, causing the first frame 100 and the second frame 300 to fold closer to each other, significantly reducing the overall volume of the support mechanism and facilitating storage. When unfolded for use, the ends of the first frame 100 and the second frame 300 restrict the relative position of the two adjustment components, ensuring that the support mechanism maintains a stable unfolded shape under load, providing reliable support for the bathtub. This hinged structure design satisfies both the functional requirements of folding and retracting and ensures structural strength during use, allowing the support mechanism to be both flexible and safe and durable. See Figure 8 as well as Figures 11-12In one embodiment, the first connecting portion 120 is provided with a first slot 122, and the inner wall of the first mounting position 321 is provided with a first extension portion 323, a first bending portion 324 and a second extension portion 325 connected in sequence. The first extension portion 323 is provided with a first protrusion 328, and the first protrusion 328 and the first bending portion 324 form a second mounting position 326. The first protrusion 328 is used to engage with the first slot 122, and the second mounting position 326 is used to engage with the side wall of the first slot 122.

[0063] See Figure 6 In one embodiment, it further includes a first fixing member 600, wherein the first connecting portion 120 and the second connecting portion 320 are respectively provided with a third through hole 123 and a fourth through hole 327, and the first fixing member 600 is inserted into the third through hole 123 and the fourth through hole 327.

[0064] In this embodiment, when the support mechanism is unfolded to the use state, the first fixing member 600 is inserted into the third through hole 123 and the fourth through hole 327. The cooperation between the fixing member and the through holes restricts the relative rotation of the first connecting part 120 and the second connecting part 320 around the first rotating shaft 500, thereby firmly locking the first frame 100 and the second frame 300 in the unfolded position. In this dual-positioning structure, the first rotating shaft 500 performs the hinge rotation function, ensuring the realization of folding and unfolding actions; the first fixing member 600 performs the locking function, preventing accidental rotation of the two adjusting components in the use state, preventing the frame from shaking or folding, and providing solid structural support for the baby bathing process. When folding and storage are required, simply pull out the first fixing member 600 to release the restriction on the rotation of the connecting parts. The first connecting part 120 and the second connecting part 320 can then rotate flexibly around the first pivot 500, allowing the first frame 100 and the second frame 300 to fold and close smoothly. Through the division of labor and cooperation between the fixing member and the pivot, reliable locking of the two frames during use is achieved, ensuring the structural stability and safety of the support mechanism, without affecting the convenience of folding and storage.

[0065] See Figure 6 Specifically, in one embodiment, the first fixing member 600 includes a first fixing part 610, a third groove 611 is provided in the middle of one end of the first fixing part 610, a first limiting part 612 is provided at the end of one end of the first fixing part 610, and a pull ring 613 is provided at the other end of the first fixing part 610.

[0066] See Figure 1 , Figure 2 and Figure 6 In one embodiment, the first frame 100 includes: The first support portion 130 is provided with a first length adjustment component 200 at both ends; At least one first support column 140, one end of which is connected to the first support portion 130. The second support portion 150 is spaced apart from the first support portion 130, and the other end of the first support column 140 is connected to the second support portion 150.

[0067] See Figure 1 , Figure 2 and Figure 6 In one embodiment, the first support column 140 includes: The first support member 141, one end of which is hinged to the first support portion 130; The second support member 142 has one end hinged to the other end of the first bracket member 141, and the other end hinged to the second support portion 150.

[0068] In this embodiment, the first frame 100 includes a first support portion 130 and a second support portion 150 spaced apart, connected by at least one first support column 140, which provides stable structural support for the frame. The first support column 140 employs a segmented hinged design, consisting of a first bracket 141 and a second support member 142. One end of the first bracket 141 is hinged to the first support portion 130, and the other end is hinged to one end of the second support member 142. The other end of the second support member 142 is hinged to the second support portion 150. When further folding and storage is required, the first support portion 130 and the second support portion 150 can be pushed closer together. At this time, the first bracket 141 and the second support member 142 rotate around the hinge point and fold together, causing the first frame 100 to fold in half as a whole, significantly reducing its longitudinal dimension.

[0069] With this design, after the length adjustment component is folded, the first frame 100 can be folded a second time through the folding of the support column, further compressing the storage space and making it easier to store the bathtub in a small space when not in use. At the same time, the hinge structure maintains sufficient structural strength when unfolded, ensuring that the first frame 100 provides stable support for the bathtub, thus meeting the dual requirements of space saving and safety.

[0070] See Figure 1 , Figure 2 and Figure 6 In one embodiment, the second frame 300 includes: The third support part 330 is provided with a second length adjustment component 400 at both ends; At least one second support column 340, one end of which is connected to the third support portion 330. The fourth support portion 350 is provided at a distance from the second support column 340, and the other end of the second support column 340 is connected to the fourth support portion 350.

[0071] See Figure 1 , Figure 2 and Figure 6 In one embodiment, the second support column 340 includes: The third support member 341, one end of which is hinged to the third support portion 330; The fourth support member 342 is hinged at one end to the other end of the third support member 341, and the other end of the fourth support member 342 is hinged to the fourth support portion 350.

[0072] In this embodiment, the second frame 300 adopts a structural design similar to the first frame 100, achieving a folding function through a hinge structure, thereby maximizing space saving. The second frame 300 includes a third support portion 330 and a fourth support portion 350 spaced apart. Both ends of the third support portion 330 are equipped with second length adjustment components 400 to ensure coordinated operation with the adjustment function of the first frame 100. The third support portion 330 and the fourth support portion 350 are connected by at least one second support column 340, which provides stable structural support for the second frame 300, ensuring the load-bearing capacity of the bathtub during use.

[0073] The second support column 340 also adopts a segmented hinge design, consisting of a third support member 341 and a fourth support member 342. One end of the third support member 341 is hinged to the third support part 330, and the other end is hinged to one end of the fourth support member 342, while the other end of the fourth support member 342 is hinged to the fourth support part 350. This multi-segment hinge structure provides a flexible rotation basis for the folding action of the second frame 300. When the second frame 300 needs to be folded for storage, the third support part 330 and the fourth support part 350 are pushed closer to each other. At this time, the third support member 341 and the fourth support member 342 will rotate around their respective hinge points and fold together, so that the second frame 300 is folded in half as a whole, greatly reducing the longitudinal dimension.

[0074] See Figure 9 The present invention also proposes a folding bathtub, including the retractable folding bathtub support mechanism as described above, wherein the bathtub body is suspended on the folding bathtub support mechanism.

[0075] Since this folding bathtub adopts all the technical solutions of all the above embodiments, it has at least all the beneficial effects brought about by the technical solutions of the above embodiments, which will not be repeated here.

[0076] The technical solution of this utility model involves providing a first length adjustment component 200 at one end of the first frame 100, and a second length adjustment component 400 at the opposite end of the second frame 300, with the first length adjustment component 200 and the second length adjustment component 400 connected by a hinge. The relative position of the two frames is adjusted by operating the first length adjustment component 200 and the second length adjustment component 400, thereby adjusting the length of the support mechanism. Furthermore, the hinged connection between the first length adjustment component 200 and the second length adjustment component 400 allows the first frame 100 and the second frame to be folded for easy storage.

[0077] The above description is merely an exemplary embodiment of the present utility model and does not limit the patent scope of the present utility model.
