Technical Field
[0001] This utility model belongs to the field of furniture and equipment installation technology, specifically an elastic support component for a shock-absorbing sofa. Background Technology
[0002] In existing technology, sofa shock absorption systems typically use a combination of serpentine springs and elastic bands for support. While this provides good elastic support, it generally suffers from the drawback of inconvenient replacement. When the elastic support components are damaged, the comfort of such shock-absorbing sofas will be significantly reduced. Furthermore, the elastic support components inside some sofas are often fixedly installed inside the sofa, requiring the disassembly of multiple interconnected parts for replacement. This makes it difficult for ordinary users to maintain and replace them themselves. Therefore, improvements are needed to address the current situation. Utility Model Content
[0003] In response to the above situation and to overcome the shortcomings of the prior art, this utility model provides an elastic support component for a shock-absorbing sofa. It effectively solves the problem that the existing sofa shock-absorbing system usually adopts a combination of serpentine springs and elastic bands for support. Although it can provide good elastic support, it generally suffers from the drawback of inconvenient replacement. When the elastic support component is damaged, the comfort of this type of shock-absorbing sofa will be greatly reduced. Moreover, the elastic support components inside some sofas are often fixedly installed inside the sofa, which requires the disassembly of multiple linkage parts for replacement, making it difficult for ordinary users to maintain and disassemble and replace them themselves.
[0004] To achieve the above objectives, this utility model provides the following technical solution: an elastic support component for a shock-absorbing sofa, comprising a base frame, mounting sleeves, serpentine springs, and elastic bands. The mounting sleeves are evenly connected to both sides of the top of the base frame. Multiple sets of serpentine springs and elastic bands are provided. Support components are evenly provided on the top of the base frame, and auxiliary components are provided inside the base frame.
[0005] The support assembly includes a serpentine spring, with connecting sleeves at both ends of the serpentine spring. Each connecting sleeve has an internal mounting groove, and each mounting groove has a positioning block connected to its internal side. One end of each positioning block is connected to a spring, and the other end of each spring is connected to the inner wall of the mounting groove. An elastic pad is connected to the top of the base frame, and a support plate is connected to the bottom of the elastic pad. Partitions are evenly distributed inside the base frame.
[0006] Preferably, the outer walls of both connecting sleeves are connected with anti-slip pads, and both anti-slip pads are elastic.
[0007] Preferably, the partitions are configured in four groups, which divide the internal space of the base frame into three groups. Each group of spaces is provided with three groups of serpentine springs and two groups of elastic bands.
[0008] Preferably, the elastic band is located at the bottom of the serpentine spring, and the elastic band and the serpentine spring are equidistantly distributed.
[0009] Preferably, the auxiliary component includes a mounting plate, both sides of which are connected to the top of the partition. The interior of both sides of the mounting plate is connected to a mounting rod, which is screwed to the partition. The elastic band is connected to the opposite side of both sides of the mounting plate. The inner wall of the base frame is evenly provided with sliding grooves on both sides. Both sides of the partition are connected to sliders, which match the sliding grooves.
[0010] Preferably, both sides of the mounting plate are connected to limit blocks, and the top of the partition is provided with a limit groove that matches the limit blocks.
[0011] Preferably, the top of the partition is provided with a groove, and a handle is connected inside the groove.
[0012] Compared with the prior art, the beneficial effects of this utility model are:
[0013] 1. The base frame serves as the basic support structure. The mounting sleeves are evenly fixed on both sides of its top for installing serpentine springs. When it is necessary to install serpentine springs, the user first lifts the elastic pad, pushes the connecting sleeves at both ends of the serpentine spring into the inside of the mounting sleeves on both sides, and makes the positioning blocks on both sides pass through the mounting sleeves and abut against them, thus completing the installation of the serpentine spring. When external force is applied to the elastic pad, the support plate transmits the pressure to the serpentine spring, and the serpentine spring absorbs the impact energy through deformation.
[0014] 2. When the spring shock absorption components inside the sofa are damaged, it is difficult for users to replace them themselves. The main reason is that its installation structure is complex and involves multiple linkage components. The two ends of the serpentine spring are fixed in the mounting sleeve through the connecting sleeve, and the positioning block inside the connecting sleeve is tightly matched with the spring. This makes it easy to remove the serpentine spring by simply pushing the positioning blocks on both sides and pushing them out of the mounting sleeve. This allows ordinary users to easily replace the serpentine spring without having to do anything extra.
[0015] 3. When the sofa is under pressure, the elastic pad presses down, causing the support plate to act on the serpentine spring. The serpentine spring then transmits the downward pressure to the elastic band. At this time, the mounting plate acts as the fixed base for the elastic band, and the elastic band is rotatably connected to the opposite sides of the mounting plates on both sides, thus allowing for automatic tension adjustment. When the elastic band is damaged, the user can rotate and remove the mounting rods on both sides to loosen the installation of the elastic band, allowing the user to easily remove and replace it for maintenance.

Detailed Implementation
[0027] 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.
[0028] Please see Figures 1-8 An elastic support component for a shock-absorbing sofa includes a base frame 100, a mounting sleeve 200, a serpentine spring 201, and an elastic band 209. The mounting sleeve 200 is evenly fixedly connected to both sides of the top of the base frame 100. Multiple sets of serpentine springs 201 and elastic bands 209 are provided. Support components are evenly provided on the top of the base frame 100, and auxiliary components are provided inside the base frame 100.
[0029] The support assembly includes a serpentine spring 201, with connecting sleeves 202 fixedly connected to both ends of the serpentine spring 201. Each connecting sleeve 202 has an internal mounting groove 203, and each mounting groove 203 has a movably connected positioning block 204. One end of each positioning block 204 is fixedly connected to a spring 205, and the other end of each spring 205 is connected to the inner wall of the mounting groove 203. An elastic pad 206 is movably connected to the top of the base frame 100, and a support plate 207 is fixedly connected to the bottom of the elastic pad 206. Partitions 208 are evenly movably connected inside the base frame 100. The base frame 100 serves as the basic support structure, and the mounting sleeves 200 are evenly fixed to its top two sides for installing the serpentine spring 201. When installing the serpentine spring 201, the user first lifts the elastic pad 206 and pushes the connecting sleeves 200 at both ends of the serpentine spring 201 into the sides. The installation of the serpentine spring 201 is completed by successfully placing the two side positioning blocks 204 inside the mounting sleeve 200 and ensuring they abut against it. When external force is applied to the elastic pad 206, the support plate 207 transmits the pressure to the serpentine spring 201. The serpentine spring 201 absorbs the impact energy through deformation. When the spring damping components inside the sofa are damaged, it is difficult for the user to replace them themselves, mainly because the installation structure is complex and involves multiple linkage components. The two ends of the serpentine spring 201 are fixed inside the mounting sleeve 200 by the connecting sleeve 202. The positioning blocks 204 inside the connecting sleeve 202 are tightly engaged with the spring 205, so that the disassembly process only requires pushing the two side positioning blocks 204 outward from the mounting sleeve 200 to easily remove the serpentine spring 201. This allows ordinary users to easily replace the serpentine spring 201 without performing any extra operations.
[0030] Anti-slip pads are fixedly connected to the outer walls of the connecting sleeves 202 on both sides. The anti-slip pads on both sides are elastic, so that the positioning blocks 204 on both sides can stably abut against the mounting sleeve 200.
[0031] The partitions 208 are set into four groups, which divide the internal space of the base frame 100 into three groups. Each group of space is equipped with three sets of serpentine springs 201 and two sets of elastic bands 209. By setting the partitions 208 into four groups and dividing the internal space of the base frame 100 into three groups, and arranging three sets of serpentine springs 201 and two sets of elastic bands 209 in each group of space, the overall support performance and stability of the shock-absorbing sofa can be significantly improved.
[0032] The elastic band 209 is located at the bottom of the serpentine spring 201. The elastic band 209 and the serpentine spring 201 are equidistantly distributed. Placing the elastic band 209 at the bottom of the serpentine spring 201 and maintaining an equidistant distribution can optimize the collaborative working effect of the shock absorption system and improve the overall support performance.
[0033] The auxiliary components include mounting plates 300, with both sides of the mounting plates 300 movably connected to the top of the partition 208. Mounting rods 301 are rotatably connected inside each of the two mounting plates 300, and each mounting rod 301 is screwed onto the partition 208. Elastic bands 209 are rotatably connected to opposite sides of the two mounting plates 300. Slide grooves 302 are evenly distributed on both sides of the inner wall of the base frame 100. Sliding blocks 303 are fixedly connected to both sides of the partition 208, and the sliding blocks 303 match the slide grooves 302. When the sofa is subjected to pressure, the elastic pads 20... 6. The downward pressure drives the support plate 207 to act on the serpentine spring 201, which in turn transmits the downward pressure to the elastic band 209. At this time, the mounting plate 300 serves as the fixed base for the elastic band 209, and the elastic band 209 is rotatably connected to the opposite sides of the mounting plates 300 on both sides, so that the tension can be automatically adjusted. When the elastic band 209 is damaged, the user can rotate and remove the mounting rods 301 on both sides to loosen the installation state of the elastic band 209, so that the user can easily remove it and replace and maintain it.
[0034] Both sides of the mounting plate 300 are fixedly connected to limit blocks 304. The top of the partition plate 208 is provided with a limit groove that matches the limit block 304, so that the mounting plate 300 can be quickly positioned and the mounting rod 301 can be stably screwed into the partition plate 208.
[0035] The top of the partition 208 has a groove, and a handle 305 is fixedly connected inside the groove, so that the user can easily pull out the partition 208.
[0036] Working principle: The base frame 100 serves as the basic support structure. Mounting sleeves 200 are evenly fixed to both sides of its top for installing serpentine springs 201. When installing serpentine springs 201, the user first lifts the elastic pad 206. By pushing the connecting sleeves 200 at both ends of the serpentine spring 201 into the interior of the mounting sleeves 200 on both sides, and ensuring the positioning blocks 204 on both sides successfully pass through and abut against the mounting sleeves 200, the installation of the serpentine spring 201 is completed. When external force acts on the elastic pad 206, the support plate 207 transmits the pressure to the serpentine spring 201. The serpentine spring 201 absorbs impact energy through deformation. When the spring shock-absorbing components inside the sofa are damaged, it is difficult for the user to replace them themselves, mainly because its installation structure is complex and involves multiple linkage components. The two ends of the serpentine spring 201 are fixed inside the mounting sleeves 200 by connecting sleeves 202. The positioning block 204 inside 202 fits tightly with the spring 205, making the disassembly process simple. Just push the positioning blocks 204 on both sides and push them out of the mounting sleeve 200 to easily remove the serpentine spring 201. This allows ordinary users to easily replace the serpentine spring 201 without any extra operations. When the sofa is under pressure, the elastic pad 206 presses down, causing the support plate 207 to act on the serpentine spring 201. The serpentine spring 201 then transmits the downward pressure to the elastic band 209. At this time, the mounting plate 300 acts as a fixed base for the elastic band 209. The elastic band 209 is rotatably connected to the opposite sides of the mounting plates 300 on both sides, thus automatically adjusting the tension. When the elastic band 209 is damaged, the user can rotate and remove the mounting rods 301 on both sides to loosen the installation of the elastic band 209, allowing the user to easily remove and replace it for maintenance.
