Description

Technical Field

[0001] The invention belongs to the technical field of spring pads, and in particular relates to a supporting combined spring pad. Background Art

[0002] The spring pads currently on the market include spring pads with double-layer springs, with soft springs on the upper part. The purpose of providing the soft springs is to improve the comfort of the spring pads, but the upper ends of the soft springs are interconnected to form an integral spring pad, which loses the elastic effect that can be achieved by each spring being able to support independently, that is, the lasting soft performance. Therefore, the only way is to increase the amount of filling materials such as sponges. However, after being used for a period of time, the resilience of the filling materials is weakened, and they are prone to aging and deformation, losing the soft elastic function they should have when they were originally made, affecting product quality or requiring replacement, resulting in waste. Summary of the invention

[0003] In order to solve the above problems, the present invention provides a supporting combined spring pad.

[0004] The technical solution of the present invention is implemented as follows: a supporting combined spring pad comprises a bottom plate, a multi-supporting support rod is arranged on the bottom plate, a sheath is arranged on the top of the support rod, a supporting spring is sheathed on the outer side of the support rod, a sheath tube is installed in the lower end of the support rod and is slidably connected with the sheath tube, the sheath tube is fixedly connected with the bottom plate, a support plate is arranged on the support rod, one end of the support spring is fixedly connected with the support plate, and the other end is fixedly connected with the bottom plate, a roller frame is arranged above the support plate, the support rod passes through the roller frame and is slidably connected with the roller group on the roller frame, and adjacent roller frames are connected by supporting springs;

[0005] Preferably, the roller group includes more than two rollers, the rollers are slidably connected to the supporting rods, and the roller frames form a connection network through supporting springs;

[0006] Preferably, a limit support is provided on the supporting rod;

[0007] Preferably, the outer edge of the sheath is connected to the supporting spring, and the movable distance between the inner edge of the sheath and the roller frame is 2-5 cm.

[0008] The beneficial effect of the present invention is that a connecting net with rollers is provided on the upper part of the supporting spring. When the spring pad is locally under pressure, the local sheath drives the supporting rod to move downward, and the supporting plate moves downward synchronously. At this time, the supporting plate compresses the supporting spring to play a soft supporting force under light pressure. When the pressure is further increased, the inner edge of the center of the sheath contacts the connecting net roller frame and continues to move downward. The connecting net here will extend downward to all sides, driving other parts of the supporting plate and the supporting spring to move downward. The mutual cooperation of the supporting spring and the connecting net can achieve a hard supporting force under heavy pressure, that is, soft support first and then hard support, combining soft and hard, and having both independent support and combined support functions. Even if the amount of fillers used is reduced, there is still a good comfort effect, the structure is simple, and it is convenient and practical. BRIEF DESCRIPTION OF THE DRAWINGS

[0013] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0014] In the description of the present invention, it is necessary to understand that the terms "upper", "lower", "front", "back", "left", "right", "top", "bottom", "inside", "outside", etc., indicating the orientation or position relationship are based on the orientation or position relationship shown in the drawings, and are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on the present invention.

[0015] See attached Figure 1-3, a supporting combined spring pad comprises a bottom plate 1, a multi-supporting support rod 7 is arranged on the bottom plate 1, a sheath 8 is arranged on the top of the support rod 7, a supporting spring 2 is sleeved on the outer side of the support rod 7, a sheath tube 10 is installed at the lower end of the support rod 7, the support rod 7 is slidably connected to the sheath tube 10, the sheath tube 10 is fixedly connected to the bottom plate 1, a support plate 4 is arranged on the support rod 7, one end of the support spring 2 is fixedly connected to the support plate 4, and the other end is fixedly connected to the bottom plate 1, a roller frame 5 is arranged above the support plate 4, and the support rod 7 Passing through the center hole of the roller frame 5 and slidingly connected with the roller group 3 on the roller frame 5, adjacent roller frames 5 are connected by supporting springs 6, the roller group 3 includes more than two rollers, the rollers are slidingly connected with the supporting rod 7, each roller frame 5 forms a connection network through the supporting spring 6, and the supporting rod 7 is provided with a limit support 9, the outer edge of the sheath 8 is connected with the supporting spring 6, the material of the outer edge is soft and foldable material, and the movable distance between the inner edge 11 of the sheath 8 and the roller frame 5 is 3cm

[0016] Specifically, when the spring pad is locally subjected to pressure, the local sheath 8 drives the supporting rod 7 to move downward with the cooperation of the roller group 3, and the support plate 4 moves downward synchronously. At this time, the support plate 4 compresses the support spring 2 to play a soft supporting force under light pressure. When the pressure is further increased, the inner edge of the sheath 8 contacts the roller frame on the connecting net, and continues to move downward after contact. Here, the connecting net will extend to the surroundings to transmit downward pressure, driving the other parts of the support plate 8 and the supporting spring 2 to move downward. The cooperation of the supporting spring 2 and the connecting net can achieve a hard supporting force under heavy pressure, that is, soft support first and hard support later, a combination of soft and hard, with both independent support and combined support functions, reducing the amount of filler used, and achieving a better comfortable use effect. When the limit support 9 drops to the bottom and contacts the top of the sheath tube 10 synchronously with the supporting rod 7, the supporting rod 7 stops falling. The supporting rod 7 can reduce wear and noise by sliding and lifting after the cooperation of the roller group 3, making it softer and quieter when used.

[0017] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical scheme and inventive concept of the present invention within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.
