Description
Technical Field
[0001] This utility model belongs to the field of household goods technology, specifically relating to a spring pad equipped with a diagonal adjustment device. Background Technology
[0002] Currently, most spring mattresses and sofa cushions on the market still use traditional connection methods for the top of the support springs, such as snap-fit connections and spring insertion. The drawback of these methods is that they cannot effectively utilize the independent support function of the support springs to provide reasonable and effective support for the user's body's contours. A common solution is to add excessive amounts of sponge or cotton filling to compensate for this deficiency. However, after a period of use, these fillings may become insufficiently supportive, causing the main use area of the spring mattress to sag. In severe cases, the spring mattress must be replaced, resulting in resource waste. Patent application number 202410440783 discloses an intelligent adjustable spring mattress. Although it uses elastic mesh and elastic rubber sheets with connecting and stretching functions, it cannot adjust the tension of the connecting body at the top of the support spring, meaning it cannot adjust the supporting force of the connecting body at the top of the support spring. Therefore, it cannot meet the user's requirement for a spring mattress that provides more reasonable support for the body's contours. Utility Model Content

The nut 16 is connected to one end of the adjusting spring 18. One end of the adjusting soft belt 11 is connected to the other end of the adjusting spring 18 through the roller assembly B13. A connecting hole 20 is provided on the base plate 1. The lower end of the adjusting screw 15 is connected to one end of the hexagonal transmission rod 21 through the universal joint 19. The other end of the hexagonal transmission rod 21 passes through the connecting hole 20 and is connected to the intelligent transmission device 5. The intelligent transmission device includes an electrical control box 25, which is connected to a servo motor 27, a pressure sensor 28, an intelligent controller 29, and a camera 30 via a circuit 26. The servo motor 27 is connected to a transmission belt 31 via a drive wheel 39, and the transmission belt 31 is connected to a drive wheel 32. The drive wheel 32 has a hexagonal connection hole 33, and the hexagonal transmission rod 21 passes through the hexagonal connection hole 33 and is connected to the drive wheel 32. The servo motor 27, the drive wheel 32, and the camera 30 are all connected to the base plate 1, and the pressure sensor 28 is connected to the diagonal assembly block 3. The hexagonal transmission rod 21 is provided with a bidirectional pressure regulating cylinder 35 in the middle. A piston 36 is installed inside the bidirectional pressure regulating cylinder 35. A hexagonal hole cover 37 is installed at the upper end of the bidirectional pressure regulating cylinder 35. The lower end of the upper section 21-1 of the hexagonal transmission rod 21 passes through the hexagonal hole cover 37 and is fixedly connected to the piston 36. A control bearing 22 is provided on the connecting hole 20. The upper end of the lower section 21-2 of the hexagonal transmission rod 21 passes through the control bearing 22 and is fixedly connected to the bottom end of the bidirectional pressure regulating cylinder 35. The outside of the bidirectional pressure regulating cylinder 35 is connected to the bidirectional pressure regulating cylinder frame 23 through the control wheel 24. The bidirectional pressure regulating cylinder frame 23 is connected to the base plate 1. The diagonal assembly block 3 is provided with a limiting groove 40, and a tension spring 41 is installed in the limiting groove 40. The other end of the adjusting soft belt 11 connected to the roller assembly A10 is connected to the tension spring 41. The distance between one end of the tension spring 41 and the roller assembly A10 is set to 1-2 cm. A control frame A44 is installed on the base plate 1 inside the support spring 2. One end of the control frame A44 is connected to the buffer spring 45, and the other end of the buffer spring 45 is connected to the limiting bracket A46. A control frame B42 is installed on the lower side of the diagonal assembly block 3, and a limiting bracket B43 is installed at the lower end of the control frame B42.An elastic pad 48 is connected above the diagonal assembly block 3, and a face mask 49 is covered above the elastic pad 48. The face mask 49 is connected to the base plate 1 on all four sides, and the pressure sensor 28 is connected to the elastic pad 48. A four-corner divider sleeve 8 is fitted on the outside of the square assembly frame 7. The four-corner divider sleeve 8 is set between four adjacent diagonal assembly blocks 3. The four-corner divider sleeve 8 has four dividing corners 9. Each dividing corner 9 is set between two adjacent diagonal assembly blocks 3. The four-corner divider sleeve 8 and the diagonal assembly blocks 3 are pressed against each other and slid up and down.
[0010] Specifically, after power is supplied to the electrical control box 25, the intelligent control unit 29 automatically controls the servo motor 27 to work according to the program set by the user and the signal transmitted by the pressure sensor 28. This drives the drive wheel 32 to rotate via the transmission belt 31, which in turn drives the lower section 21-2 of the hexagonal transmission rod 21 to rotate. Through the linked bidirectional pressure regulating cylinder 35 and the hexagonal hole cover 37, the upper section 21-1 of the hexagonal transmission rod 21 rotates. This, in turn, drives the adjusting screw 15 to rotate via the universal joint 19. The nut 16, through the action of the adjusting screw 15, causes the adjusting spring 18 to rise or fall. The rise or fall of the adjusting spring 18 changes the tension on the adjusting soft belt 11. Simultaneously, the rolling connection between the adjusting soft belt 11 and the roller group A10 and roller group B13 reduces motion resistance. The diagonal combination block 3 and the four-corner separating sleeve 8 are connected by the tension of the connecting soft belt 11. The change in force causes a change in the mutual squeezing force, which in turn causes a change in the supporting force of the diagonal assembly 4 connected to the top of the supporting spring 2 on the spring pad. Therefore, by adjusting the tension of the adjusting soft belt 10, the supporting force of a certain area of the spring pad can be adjusted, so as to achieve the effect of soft support or hard support in a certain area of the spring pad. The universal joint 19 can improve the flexibility of the spring pad. For example, when the spring pad needs to have a slight lateral sway function, the hexagonal transmission rod 21 connected longitudinally on the diagonal adjustment device 6 can achieve the vibration effect of the square assembly frame 7 with sway function through the universal joint 19. The four corner separator sleeves 8 are set between adjacent diagonal assembly blocks 3 through the separator angle 9, which can separate adjacent diagonal assembly blocks 3, thereby reducing the friction and collision generated when the diagonal assembly blocks 3 rise and fall with each other. The upper surface area of the diagonal assembly block is set to 30-60 square centimeters, and the upper surface area of the four corner divider sleeves 8 is set to 10-30 square centimeters. This is mainly to ensure that the structural dimensions of the spring mattress and sofa cushion designed and manufactured are more in line with their functions, thus saving costs while achieving the soft and comfortable effect of the spring mattress. A limiting groove 40 is provided. By adjusting the connection between the soft straps 11 and the tension springs 41, the telescopic movement distance of each connecting soft strap 11 can be controlled between 1-2 centimeters. The telescopic movement distance of the connecting soft straps 11 controls the height difference between the diagonal assembly block 3 and the four corner divider sleeves 8. The size of this height difference determines the effectiveness of the independent support function produced by the combination of the support spring 2 and the diagonal assembly 4, that is, the effectiveness of the spring mattress in supporting the convex and concave parts of the human body.By setting control bearings 22 in the gaps between four adjacent support springs 2, and allowing the hexagonal transmission rod 21 to pass through the control bearings 22, the internal structural space of the spring pad is fully utilized. A bidirectional pressure regulating cylinder 35 is installed in the middle of the hexagonal transmission rod 21, allowing the piston 36 to smoothly raise and lower the upper section 21-1 of the hexagonal transmission rod 21 under the action of lubricating oil. This ensures long-term use without abnormal noise and improves the flexibility of the spring pad. The intelligent control unit 29 on the intelligent transmission device 5 displays the operating status of the various components connected to the spring pad in real time via the camera 30, enabling timely maintenance and repair of any problems. The corresponding upper and lower positions of the control frame, buffer spring 45, and limit support control the descent height of the diagonal assembly block 3 due to excessive or rapid pressure, reducing damage to the relevant components. The purpose of setting the elastic pad 48 is to increase the flexibility of the spring pad by leveraging its elasticity. Since the elastic pad 48 is connected to the upper part of the diagonal assembly block 3, its lifting and lowering process does not affect the support function of the spring pad. Furthermore, the elastic pad 48 reduces the thickness of the face mask 49, indirectly improving the soft support of the spring pad and reducing the amount of filling materials such as cotton and silk used in the face mask 49. The diagonal adjustment device enhances the independent support function of the diagonal assembly 4, giving the spring pad the advantage of not denting or deforming after long-term use. This invention, through the above-mentioned technical design, overcomes the shortcomings and deficiencies of the prior art, providing consumers with higher-quality products and improving their rest and health.

Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present utility model, based on the technical solution and inventive concept of the present utility model, should be included within the scope of protection of the present utility model.
