Description

Technical Field

[0001] This utility model relates to the field of spring mattress technology, and in particular to an adjustable segmented spring mattress. Background Technology

[0002] A segmented spring mattress is designed by dividing the mattress into segments, each corresponding to a different part of the body, with each segment having a different spring tension, thus making the body more comfortable when lying on a segmented spring mattress.

[0003] Reference document 1 discloses a nine-zone spring mattress in Chinese patent CN220734941U. This nine-zone spring mattress, through the setting of related mechanisms, allows the support force of the internal springs to be adjusted, enabling the nine-zone spring mattress to better support the nine zones of the human body, increasing the practicality of the nine-zone spring mattress, and reducing the production difficulty and cost of the nine-zone spring mattress. Prior art document 2 discloses a nine-zone sensor spring mattress in Chinese patent CN222397747U. This nine-zone sensor spring mattress is an improvement upon prior art document 1. The inclusion of a limiting component allows users to quickly adjust the mattress while simultaneously fixing it in place, thus increasing the mattress's efficiency and improving its performance. The adjustment component, in conjunction with the limiting component, compresses the cushioning springs, thereby adjusting the mattress's support strength. However, in both of the aforementioned nine-zone spring mattresses, in Reference Document 1, the mattress support sleeve is slidably connected inside the mattress fixing sleeve, and the mattress support spring inside the mattress fixing sleeve supports the mattress support sleeve; in Reference Document 2, the second guide plate is slidably installed in the guide groove on the first guide plate, and the cushioning spring supports the top plate on the second guide plate. Therefore, the springs in both reference documents are restricted, only allowing for up-and-down elastic movement, and cannot bend left or right. Therefore, both reference documents have the following defects: Firstly, when a person lies on a mattress, the springs are only compressed vertically, resulting in several compressed elastic support components forming a stepped shape. However, the surface of the human body is curved, so the top of the elastic support components cannot fully conform to the surface of the human body, affecting comfort.

[0004] Secondly, the components used to adjust the spring support are located under the mattress board. Therefore, when adjusting, the entire spring mattress needs to be flipped over. However, because spring mattresses have many internal spring support components, they are very heavy, making it inconvenient, time-consuming, and laborious to adjust the spring support. Utility Model Content

[0005] The purpose of this utility model is to at least solve one of the technical defects described in the background art.

[0006] Therefore, one objective of this utility model is to propose an adjustable segmented spring mattress, which aims to solve the problems of poor comfort and inconvenience, time and effort in adjusting the firmness of the two existing nine-zone spring mattresses.

[0007] To achieve the above objectives, one embodiment of the present invention provides an adjustable segmented spring mattress, including a mattress board. The top of the mattress board is provided with multiple elastic support components. Each elastic support component includes a support cylinder. A lead screw is rotatably connected to the middle of the support cylinder. A lifting plate is threadedly connected to the outer surface of the lead screw, and the lifting plate is slidably connected inside the support cylinder. A support spring is provided at the top of the lifting plate. A cloth cover is fitted onto the outer surface of the support spring, and the cloth cover is fixed to the support cylinder. An insertion hole is provided at the center of the top of the cloth cover.

[0008] The beneficial effects are as follows: The fabric cover restricts the height of the top of the support spring, allowing a tool to be inserted into the elastic support assembly through the insertion hole. By rotating the screw, the height of the lifting plate can be adjusted, thereby adjusting the height of the bottom of the support spring. This compresses or extends the support spring, adjusting the support force of the elastic support assembly. Furthermore, the upper part of the support spring is located above the support cylinder, allowing it to bend according to the curvature of the human body during use, fully conforming to the body and improving comfort. Adjusting the elastic support assembly does not require flipping the mattress, making the operation simple, time-saving, and labor-saving.

[0009] Furthermore, the top of the elastic support component is provided with a cushioning pad, the outer surface of the mattress board is fixedly connected with a rim, and the outer surfaces of the cushioning pad and the elastic support component are covered with a protective cover. The rim and the protective cover are connected by a zipper, which facilitates the removal and installation of the protective cover. After the protective cover is removed, the cushioning pad can be taken off, at which point all the elastic support components can be seen and adjusted accordingly.

[0010] Furthermore, a slot is provided at the center of the lifting plate, and a threaded sleeve is welded and fixed at the center of the bottom of the lifting plate. The lifting plate is threadedly connected to the outer surface of the lead screw through the threaded sleeve.

[0011] In a preferred embodiment, multiple guide columns are fixedly connected to the bottom of the support cylinder, and multiple guide holes are opened at the bottom of the lifting plate. The multiple guide columns are slidably inserted into the multiple guide holes to limit the lifting plate and prevent the lifting plate from rotating along with the lead screw during the rotation process.

[0012] In a preferred embodiment, a bracket is fixedly installed on the top of the guide post, and an avoidance hole is provided in the middle of the bracket, with the lead screw located inside the avoidance hole, and the two structures do not contact each other.

[0013] Furthermore, a screw is fixedly connected to the top of the guide post, and a through hole is provided at the edge of the bracket. The bracket is sleeved on the outer surface of the screw through the through hole at the edge, and a nut is threadedly connected to the outer surface of the screw to fix the bracket.

[0014] Furthermore, a square connecting shaft is fixedly connected to the top of the lead screw, and a connector is slidably sleeved on the outer surface of the connecting shaft. The connector is located above the bracket, and rotating the connector can drive the lead screw to rotate. A hexagonal head is fixedly connected to the top of the connector. By using a T-shaped socket wrench on the outer surface of the hexagonal head, the connector can be rotated.

[0015] Furthermore, a return spring is sleeved on the outer surface of the top end of the lead screw, and the return spring provides elastic support to the connector. A support rod is fixedly connected to the top of the bracket, and a sleeve is fixedly connected to the top end of the support rod. The inner wall of the sleeve is provided with several toothed grooves, and several racks that are adapted to the toothed grooves are fixedly connected to the outer surface of the top end of the connector.

[0016] The beneficial effect is that when the reset spring support connector is inserted into the sleeve, the rack inserts into the tooth groove, making the connector unable to rotate, thus preventing the lead screw from rotating. Therefore, the problem of the lead screw rotating during mattress use, causing the support spring support force to change, can be avoided.

[0017] In a preferred embodiment, a positioning ring is fixedly connected to the bottom end of the fabric cover, a positioning sleeve is threadedly connected to the top end of the support cylinder, and a pressure ring is fixedly connected to the inner wall of the top end of the positioning sleeve. The pressure ring presses down on the positioning ring, thereby fixing the fabric cover to the top of the support cylinder.

[0018] The beneficial effects are: the fabric cover is detachable, so it is convenient to replace the support spring and fabric cover individually in the future, without having to replace the entire elastic support assembly, thus saving on maintenance costs in the future.

[0019] Furthermore, a positioning cylinder is fixedly connected to the top edge of the lifting plate, and the support spring is inserted into the inside of the positioning cylinder to prevent the bottom end of the support spring from swaying left and right.

[0033] This invention provides an adjustable segmented spring mattress.

[0034] Example 1: like Figure 1 , Figure 8 and Figure 9 As shown, it includes a mattress board 1 and multiple elastic support components. The top of the elastic support components is provided with a cushioning pad 11. The outer surface of the mattress board 1 is fixedly connected with a rim 12. The outer surfaces of the cushioning pad 11 and the elastic support components are covered with protective covers 13. The rim 12 and the protective covers 13 are connected by a zipper 14.

[0035] Please see Figure 2 The elastic support assembly includes a support cylinder 2, a lifting plate 3 that can be lifted and connected inside the support cylinder 2, a bracket 4, a connector 5, a cloth sleeve 6, and a positioning sleeve 7. Please see Figures 2-4 A slot is provided at the center of the bottom of the support cylinder 2, and a bearing is fixedly connected in the slot. A lead screw 21 is fixedly connected in the inner ring of the bearing, so that the lead screw 21 is rotatably connected to the middle of the support cylinder 2. The lifting plate 3 is slidably connected inside the support cylinder 2. A slot is provided at the center of the lifting plate 3, and a threaded sleeve 31 is welded and fixed at the center of the bottom of the lifting plate 3. The lifting plate 3 is threadedly connected to the outer surface of the lead screw 21 through the threaded sleeve 31. Multiple guide posts 22 are fixedly connected to the bottom of the support cylinder 2. Multiple guide holes 32 are provided at the bottom of the lifting plate 3. The multiple guide posts 22 are slidably inserted into the multiple guide holes 32, so that rotating the lead screw 21 can drive the lifting plate 3 to rise and fall. A positioning cylinder 33 is fixedly connected to the top edge of the lifting plate 3. A support spring 34 is inserted inside the positioning cylinder 33. By adjusting the height of the lifting plate 3, the height of the bottom end of the support spring 34 can be adjusted.

[0036] Please see Figure 2-3 and Figures 5-6The top of the guide post 22 is fixedly connected to the screw 23. The edge of the bracket 4 is provided with a through hole 41 and the middle of the bracket 4 is provided with a clearance hole 42. The bracket 4 is sleeved on the outer surface of the screw 23 through the through hole 41 at the edge. The screw 21 is located in the clearance hole 42 and the two structures do not contact each other. The outer surface of the screw 23 is threaded with a nut to fix the bracket 4. A square connecting shaft 24 is fixedly connected to the top of the lead screw 21. A square connecting hole 51 is opened at the bottom of the connector 5. The connector 5 is slidably sleeved on the outer surface of the connecting shaft 24 through the connecting hole 51. The connector 5 is located above the bracket 4. Rotating the connector 5 can drive the lead screw 21 to rotate. A hexagonal head 52 is fixedly connected to the top of the connector 5. The connector 5 can be rotated by using a T-shaped socket wrench on the outer surface of the hexagonal head 52. A return spring 43 is sleeved on the outer surface of the top end of the lead screw 21. The return spring 43 is located between the bracket 4 and the connector 5, providing elastic support for the connector 5. A support rod 44 is fixedly connected to the top of the bracket 4, and a sleeve 45 is fixedly connected to the top end of the support rod 44. The inner wall of the sleeve 45 is provided with several toothed grooves 46. Several racks 53 that are adapted to the toothed grooves 46 are fixedly connected to the outer surface of the top end of the connector 5. When the return spring 43 supports the connector 5 inserted into the sleeve 45, the racks 53 are inserted into the toothed grooves 46, making it impossible for the connector 5 to rotate. After the top end of the rack 53 abuts against the top end of the toothed groove 46, it can limit the height of the connector 5 and prevent the connector 5 from sliding out of the top of the sleeve 45. When downward pressure is applied to the connector 5, the return spring 43 is compressed, and the connector 5 slides downward out of the sleeve 45, thereby allowing the connector 5 to rotate.

[0037] Please see Figure 2 and Figure 7 The cloth sleeve 6 is fitted onto the outer surface of the support spring 34, and a positioning ring 61 is fixedly connected to the bottom end of the cloth sleeve 6. The positioning ring 61 overlaps the top of the support cylinder 2. The positioning sleeve 7 is threadedly connected to the top of the support cylinder 2, and a pressure ring 71 is fixedly connected to the inner wall of the top of the positioning sleeve 7. The pressure ring 71 presses down on the positioning ring 61, thereby fixing the cloth sleeve 6 to the top of the support cylinder 2. An insertion hole 62 is provided at the center of the top of the cloth sleeve 6. A T-shaped socket wrench can be inserted through the insertion hole and then fitted onto the surface of the hexagonal head 52, thereby applying pressure to the connector 5 and applying torque to the hexagonal head 52.

[0038] The working principle of this utility model is as follows: When adjusting the supporting force of the local elastic support component, the protective cover 13 is removed through the zipper 14, and the buffer pad 11 is taken off, so that all the elastic support components can be seen. Then, the T-shaped socket wrench is inserted into the elastic support component through the insertion hole 62, so that the T-shaped socket wrench is connected to the hexagonal head 52, and pressure is applied to the connector 5, so that the connector 5 slides downward from the sleeve 45. At this time, the connector 5 can be rotated, which drives the lead screw 21 to rotate, thereby adjusting the height of the lifting plate 3, and realizing the purpose of adjusting the height of the bottom end of the support spring 34. Since the height of the top end of the support spring 34 is limited by the cloth cover 6, the raising or lowering of the lifting plate 3 will cause the support spring 34 to be adjusted. 4. Compression or extension can adjust the support force of the support spring 34. After adjustment, slowly lift the T-shaped socket wrench to reset the spring 43 and lift the connector 5, so that the connector 5 is inserted into the sleeve 45 (if the rack 53 on the connector 5 is not aligned with the tooth groove 46, causing the connector 5 to be unable to be inserted into the sleeve 45, the T-shaped socket wrench can be used to slightly rotate the connector 5 clockwise or counterclockwise so that the rack 53 corresponds to the tooth groove 46). With the rack 53 inserted into the tooth groove 46, the connector 5 can be limited, so that the connector 5 cannot rotate, and thus the screw 21 cannot rotate, avoiding the problem that the screw 21 rotates during mattress use, causing the support force of the support spring 34 to change.
