Description

Technical Field

[0001] This utility model relates to the field of support structure technology, and more specifically, to a gradient density composite sponge support structure. Background Technology

[0002] As people's demands for comfort and functionality increase, foam support structures are being used more and more widely in sofas, mattresses, medical equipment and other fields. Traditional foam support structures mostly use foam materials of a single density, which have a uniform density distribution and lack adjustability. After long-term use, they are prone to collapse and deformation, resulting in a decrease in support and an inability to effectively distribute pressure.

[0003] However, sponge support structures are generally fixed, making it difficult to adjust them flexibly according to the needs of different users or different usage scenarios, and thus failing to achieve personalized support effects.

[0004] There are currently no effective solutions to the problems in the relevant technologies. Utility Model Content

[0005] In view of the problems in the related technologies, this utility model proposes a gradient density composite sponge support structure to overcome the above-mentioned technical problems existing in the existing related technologies.

[0006] Therefore, the specific technical solution adopted by this utility model is as follows:

[0007] A gradient density composite sponge support structure includes a support frame one, an adjustment component on the inner wall of the support frame one, and adjustment rods one on both sides of one inner wall of the support frame one. A support frame two is provided on the surface of the adjustment rods one, and multiple adjustment ratchet wheels are provided on both sides of the support frame two. Adjustment blocks are engaged with the teeth of the adjustment ratchet wheels. A limiting post is in contact with one side of the adjustment block, and a spring is connected to the other side of the adjustment block. A limiting post is provided at one end of the spring, and adjustment rods two pass through the limiting post and the adjustment block. One end of the limiting post and one end of the adjustment rod two are connected to the inner side of the support frame one.

[0008] Furthermore, in order to better support the gradient density composite sponge, support components are provided on support frame one and support frame two. The support components include mounting slots that are evenly distributed on support frame one, wherein the inner walls of multiple mounting slots are provided with serpentine springs, and the inner walls of multiple mounting slots are nailed with support bandages, which are threaded onto the surface of the serpentine springs.

[0009] Furthermore, in order to better place the gradient density composite sponge and increase its density, gradient density composite sponge one is set on the support bandage and the serpentine spring. One side of gradient density composite sponge one is bonded to support frame one and support frame two, and gradient density composite sponge two is bonded to the inner wall of gradient density composite sponge one.

[0010] Furthermore, in order to better assist in restricting the gradient density composite sponge, multiple auxiliary spring pieces are provided on both sides of the outer wall of support frame one and support frame two. One end of the auxiliary spring piece is provided with a limiting plate, and one side of the limiting plate contacts the side of gradient density composite sponge one and gradient density composite sponge two.

[0011] Furthermore, in order to better install the gradient density composite sponge support structure, multiple mounting holes are provided on the support frame, and fixing screws are threaded onto the inner wall of the mounting holes.

[0012] Furthermore, in order to better fix the gradient density composite sponge support structure, a fixing plate is connected to the fixing screw, and one side of the fixing plate contacts one side of the support frame.

[0013] The beneficial effects of this utility model are as follows:

[0014] (1) By setting the adjustment component in the first support frame, the support angle can be easily adjusted flexibly to meet the personalized needs of different users for the support angle. This effectively avoids the problem of insufficient comfort caused by the inability of the traditional fixed support structure to adapt to different human body curves. It can also provide stable support force. At the same time, the support components set in the first and second support frames can enhance the strength and stability of the entire support structure, so that the sponge can be supported more evenly when under force, preventing local collapse and deformation, thereby extending the service life and providing users with more reliable support protection.

[0015] (2) By setting auxiliary springs and limiting plates in support frame one and support frame two, the support structure can adaptively adjust according to the body pressure distribution of different users, thereby assisting in limiting and adjusting the gradient density composite sponge. At the same time, the fixing screws and fixing plates set in support frame one facilitate the installation and fixing of the gradient density composite sponge support structure, which is conducive to quickly and firmly installing the support structure on the sofa frame or other base, improving installation efficiency, and also facilitating later disassembly and maintenance, enhancing the practicality and operability of the product.

[0024] Example 1:

[0025] like Figures 1-3As shown, a gradient density composite sponge support structure according to an embodiment of the present invention includes a support frame 1 for supporting the gradient density composite sponge. An adjustment component 2 is provided on the inner wall of the support frame 1. The adjustment component 2 includes adjustment rods 201 on both sides of one inner wall of the support frame 1 for adjusting the angle of a support frame 202. The surface of the adjustment rods 201 is provided with the support frame 202. Two adjustment ratchet wheels 203 are provided on both sides of the support frame 202 to assist in limiting the angle of the support frame 202. The teeth of the adjustment ratchet wheels 203... An adjusting block 204 is engaged with the adjusting ratchet 203 to restrict the adjusting ratchet 203. One side of the adjusting block 204 contacts a limiting post 205 to restrict the adjusting block 204. The other side of the adjusting block 204 is connected to a spring 206 to assist in restricting the adjusting block 204. One end of the spring 206 is provided with a limiting block 207. An adjusting rod 208 passes through the limiting block 207 and the adjusting block 204 to adjust the limiting block 207 and the adjusting block 204. One end of the limiting post 205 and one end of the adjusting rod 208 are connected to one side of the inside of the support frame 1.

[0026] The support frame 1 has four mounting holes, and the inner wall of the mounting holes is threaded with fixing screws 8 for fixing the support frame 1. Fixing plates 9 are connected to the fixing screws 8 for auxiliary fixing of the support frame 1. In actual use, the fixing plates 9 and fixing screws 8 are connected to the sofa frame, and one side of the fixing plate 9 contacts one side of the support frame 1.

[0027] Example 2:

[0028] like Figures 1-4 As shown, according to an embodiment of the present invention, a gradient density composite sponge support structure is provided on a support frame 1 and a support frame 202. The support component 3 includes mounting grooves 301 evenly distributed on the support frame 1. The inner walls of the mounting grooves 301 are provided with serpentine springs 302. The serpentine springs 302 and the inner walls of the mounting grooves 301 are connected by screws in actual use. The serpentine springs 302 are provided with balance lines (not shown in the figure) in actual use. In addition, the inner walls of the mounting grooves 301 are nailed with support bandages 303, and the support bandages 303 are threaded through the surface of the serpentine springs 302.

[0029] A gradient density composite sponge 4 is provided on the support bandage 303 and the serpentine spring 302. One side of the gradient density composite sponge 4 is bonded to the support frame 1 and the support frame 202. A gradient density composite sponge 5 is bonded to the inner wall of the gradient density composite sponge 4. Two auxiliary springs 6 are provided on both sides of the outer wall of the support frame 1 and the support frame 202 for adaptive adjustment according to the placement of the gradient density composite sponge. One end of the auxiliary spring 6 is provided with a limiting plate 7 for auxiliary restriction of the gradient density composite sponge. One side of the limiting plate 7 is in contact with the side of the gradient density composite sponge 4 and the gradient density composite sponge 5.

[0030] To facilitate understanding of the above-mentioned technical solutions of this utility model, the working principle or operation method of this utility model in actual process will be described in detail below.

[0031] In summary, with the help of the above-mentioned technical solution of this utility model, during use, the user can flexibly adjust the support angle through the adjusting rod 201 set on the inner wall of the support frame 1. The adjusting rod 201 is connected to the support frame 202, and the teeth of the adjusting ratchet 203 engage with the adjusting block 204. By pressing the adjusting block 204 to overcome the resistance of the spring 206, the adjusting ratchet 203 is released from locking, thereby adjusting the angle of the support frame 202. After the adjustment is completed, the spring 206 pushes the limiting block 207 to reset, fixing the position of the adjusting block 204 and ensuring the angle is stable.

[0032] A serpentine spring 302 and a support bandage 303 are installed in the mounting groove 301 of the support frame 1. The serpentine spring 302 provides lateral elastic support, and the support bandage 303 is stretched longitudinally. The two are interwoven to form a grid structure, which disperses the force and enhances the overall rigidity. The gradient density composite sponge 4 and gradient density composite sponge 5 set in the support frame 1 and the support frame 202 can evenly disperse the pressure in different areas by density gradient, prevent local collapse, and conform to the curve of the human body.

[0033] The auxiliary spring pieces 6 on both sides of the support frame 1 and the support frame 202 are connected to the limiting plate 7. When the sponge is deformed by force, the auxiliary spring pieces 6 are bent by pressure, pushing the limiting plate 7 to apply dynamic constraint force to the side of the sponge to avoid excessive deformation. At the same time, the support strength is adaptively adjusted according to the pressure distribution.

[0034] The fixing screws 8 on the support frame 1 cooperate with the fixing plate 9. By screwing them into the threaded holes of the external frame, such as the sofa base, quick installation can be achieved. The fixing plate 9 increases the contact area, ensuring the stability of the support structure and facilitating later disassembly and maintenance.

[0035] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
