Mattress capable of releasing pressure and buffering

Abstract

The utility model relates to the technical field of mattresses, in particular to a pressure-releasing and buffering mattress which comprises a wrapping layer, a covering layer is arranged at the top end of the wrapping layer, and a supporting spring is arranged between the wrapping layer and the covering layer. A protection assembly used for protecting the supporting spring is arranged in an inner cavity of the wrapping layer and comprises a main telescopic rod and an auxiliary telescopic rod which are fixedly installed in the wrapping layer, and the top end of the main telescopic rod is fixedly connected with a supporting plate. By arranging the protection assembly, when the mattress is stressed, the supporting springs in the protection assembly can play a role in pressure relief and buffering, and in the stress shrinkage process, the covering layer at the top end of the protection assembly moves downwards to apply pressure to the supporting plate, so that the supporting plate applies pressure to the main telescopic rod at the bottom end, and the main telescopic rod is prevented from being damaged. When the main telescopic rod contracts under pressure, the auxiliary telescopic rod extends, so that the supporting spring does not contract under the matching action of the main telescopic rod and the auxiliary telescopic rod, and the situation that the supporting spring is damaged due to the fact that the stress is too large and exceeds the contraction range is avoided.

Description

Technical Field

[0001] The utility model relates to the technical field of mattresses, in particular to a pressure-releasing and cushioning mattress. Background Art

[0002] A mattress is a large, usually rectangular cushion used to support a lying person. It is designed to be used as a bed, or as part of a bed placed on a bed frame, to ensure that consumers get healthy and comfortable sleep. In order to improve comfort and increase the pressure relief and cushioning effect, a support layer of springs is often added to the mattress.

[0003] However, the spring support layer in most existing mattresses does not have a protective structure. Therefore, when the mattress is subjected to external pressure, such as overload, jumping on the bed, or often sitting on the edge of the bed, the springs will frequently exceed their contraction range due to the overload, resulting in damage, gradual weakening of elasticity, and even deformation or breakage, making the mattress unable to rebound.

[0004] For this reason, a mattress capable of releasing pressure and providing cushioning is proposed. Utility Model Content

[0005] The purpose of the present invention is to provide a pressure-releasing and cushioning mattress to solve the problem, as mentioned in the background art, that the spring support layer of most mattresses does not have a protective structure. As a result, when the mattress is subjected to external pressure, such as overload, jumping on the bed, or frequent sitting on the edge of the bed, the springs will frequently exceed their contraction range due to the overload, resulting in damage, gradual weakening of elasticity, and even deformation or breakage, resulting in the inability of the mattress to rebound.

[0006] To achieve the above-mentioned objectives, the present invention provides the following technical solutions: a pressure-releasing and cushioning mattress, comprising a wrapping layer, a covering layer being provided on the top of the wrapping layer, and a support spring being provided between the wrapping layer and the covering layer; a protective component being provided in the inner cavity of the wrapping layer for protecting the support spring, the protective component comprising a main telescopic rod and a secondary telescopic rod fixedly installed in the wrapping layer, the top of the main telescopic rod being fixedly connected to a support plate; and a clamping component being provided at the bottom end of the inner cavity of the wrapping layer for fixing the support spring, the clamping component comprising a limiting sleeve being provided in the wrapping layer, a pressure block being provided in the limiting sleeve, and a rotating rod being rotatably connected to the pressure block.

[0007] Preferably, a connecting tube is fixedly connected between the main telescopic rod and the auxiliary telescopic rod, a first return spring is fixedly connected between the support plate and the main telescopic rod, a circular plate is fixedly connected to the top end of the auxiliary telescopic rod, and a tension spring is fixedly connected between the circular plate and the auxiliary telescopic rod.

[0008] Preferably, a circular slot is provided on the support plate, and the support spring passes through the circular slot.

[0009] Preferably, a sliding groove is provided in the limiting sleeve, and the pressure block is slidably connected in the sliding groove. An arc groove adapted to the support spring is provided on the pressure block, and the rotating rod and the limiting sleeve are threadedly connected.

[0010] Preferably, a frame layer is fixedly connected to the covering layer, and a card slot is provided in the frame layer, a card plate is slidably connected to the wrapping layer, a limit plate is fixedly installed on the card plate, and a second return spring is fixedly connected between the limit plate and the wrapping layer.

[0011] Preferably, the card plate and the frame layer are both provided with inclined surfaces of the same angle, and when the main telescopic rod and the auxiliary telescopic rod are stationary, the main telescopic rod is positioned higher than the auxiliary telescopic rod.

[0012] Preferably, a pull plate is fixedly connected to the card plate, and a non-slip rubber pad is provided on the pull plate.

[0013] Beneficial effects of the utility model:

[0014] The utility model provides a protective component so that when the mattress is under pressure, the support spring inside it can play a role of pressure relief and buffering. During the process of its contraction under force, the covering layer at its top moves downward to apply pressure to the support plate, so that the support plate applies pressure to the main telescopic rod at the bottom end. When the main telescopic rod is contracted under pressure, the secondary telescopic rod is extended. Therefore, under the cooperation of the main telescopic rod and the secondary telescopic rod, the support spring no longer contracts, so that it will not be damaged due to excessive force exceeding its contraction range. In addition, a clamping component is provided to rotate the rotating rod to drive the pressure block to move downward, so that the pressure block can limit and fix the support spring to keep it stable. At the same time, reverse rotation can make the pressure block disengage from the support spring and cancel the fixation, so that it is easy to remove and replace it.

[0022] In order to make the purpose, technical solutions and advantages of the present invention more clearly understood, the present invention is further described in detail below in conjunction with specific embodiments.

[0024] like Figures 1 to 5As shown, a specific embodiment of the present invention provides a pressure-releasing and cushioning mattress, comprising a wrapping layer 1, a covering layer 2 being provided at the top of the wrapping layer 1, and a supporting spring 3 being provided between the wrapping layer 1 and the covering layer 2; a protective component for protecting the supporting spring 3 is provided in the inner cavity of the wrapping layer 1. By providing the protective component, the supporting spring 3 can be protected, thereby preventing it from exceeding its contraction range and causing damage when frequently subjected to large pressure. The protective component comprises a main telescopic rod 4 and a secondary telescopic rod 5 fixedly mounted in the wrapping layer 1, the main telescopic rod 4 and the secondary telescopic rod 5 can be filled with hydraulic oil, the top of the main telescopic rod 4 is fixedly connected to a support plate 6, and also comprises a clamping component provided at the bottom end of the inner cavity of the wrapping layer 1 for fixing the supporting spring 3. By providing the clamping component, the supporting spring 3 can be quickly fixed, limited or disassembled, thereby facilitating its replacement. The clamping component comprises a limiting sleeve 7 provided in the wrapping layer 1, a pressure block 8 is provided in the limiting sleeve 7, and a rotating rod 9 is rotatably connected to the pressure block 8.

[0025] like Figures 1 to 5 As shown, specifically, a connecting tube 10 is fixedly connected between the main telescopic rod 4 and the secondary telescopic rod 5, a first return spring 11 is fixedly connected between the support plate 6 and the main telescopic rod 4, a circular plate 12 is fixedly connected to the top of the secondary telescopic rod 5, and a tension spring 13 is fixedly connected between the circular plate 12 and the secondary telescopic rod 5, a circular slot hole 14 is provided on the support plate 6, and the support spring 3 passes through the circular slot hole 14. When the entire mattress is subjected to excessive pressure, the covering layer 2 is forced to sink downward and squeeze the supporting spring 3 at the bottom. At this time, the supporting spring 3 is forced to shrink and move downward under the action of the covering layer 2 until the covering layer 2 moves downward and contacts the support plate 6, causing the support plate 6 to move downward under pressure, and the downward moving support plate 6 squeezes the main telescopic rod 4 at the bottom and causes the main telescopic rod 4 and the first return spring 11 to shrink. During the contraction process, the main telescopic rod 4 pushes the hydraulic oil in the inner cavity to flow to the secondary telescopic rod 5 through the connecting tube 10, so that the hydraulic oil pushes the secondary telescopic rod 5 and the tension spring 13 to stretch it. When the main telescopic rod 4 and the auxiliary telescopic rod 5 are stationary, the main telescopic rod 4 is higher than the auxiliary telescopic rod 5. When the main telescopic rod 4 is shortened and the auxiliary telescopic rod 5 is extended, the support plate 6 moves downward and the circular plate 12 moves upward. In this process, the circular plate 12 contacts the support plate 6, so that the upward moving circular plate 12 provides support for the support plate 6, preventing it from moving downward, thereby preventing the covering layer 2 from moving downward and the supporting spring 3 from contracting. At this time, it protects the supporting spring 3, so that it will not be damaged by excessive force exceeding its contraction range. When there is no pressure, the auxiliary telescopic rod 5 contracts under the reaction force of the tension spring 13 and pushes the hydraulic oil to flow to the main telescopic rod 4, and pushes the top support plate 6 to return to its original position under the cooperation of the reaction force of the first return spring 11. At this time, the support spring 3 pushes the top covering layer 2 to return to its original position under the reaction force.

[0026] like Figures 1 to 5 As shown, specifically, the covering layer 2 is fixedly connected with a frame layer 16, and a card slot 17 is provided in the frame layer 16, and a card plate 18 is slidably connected in the wrapping layer 1, and a limit plate 19 is fixedly installed on the card plate 18, and a second return spring 20 is fixedly connected between the limit plate 19 and the wrapping layer 1, and a pull plate 21 is fixedly connected to the card plate 18, and a non-slip rubber pad is provided on the pull plate 21. When the supporting spring 3 is replaced, the pull plate 21 is pulled to drive the card plate 18 to move, so that the card plate 18 is disengaged from the card slot 17. At this time, the moving card plate 18 drives the limit plate 19 to move, so that the second return spring 20 is forced to contract and generate a reaction force. After the card plate 18 is disengaged from the card slot 17, the covering layer 2 and the frame layer 16 can be removed from the wrapping layer 1, a sliding groove 15 is provided in the limiting sleeve 7, and the pressure block 8 is slidably connected in the sliding groove 15, and the pressure block 8 is provided with an arc groove adapted to the supporting spring 3, and the rotating rod 9 is connected to the limit The sleeves 7 are threadedly connected, and after removing the covering layer 2, the pull plate 21 is loosened so that the card plate 18 is reset under the reaction force of the second return spring 20, and the rotating rod 9 is rotated so that the rotating rod 9 drives the pressure block 8 to gradually disengage from the supporting spring 3, that is, the limiting fixation of the supporting spring 3 is cancelled. Then the supporting spring 3 can be taken out for replacement. After the replacement is completed, the rotating rod 9 is rotated in the opposite direction to push the pressure block 8 to move downward in the sliding groove 15 and make the arc groove limit and fix the supporting spring 3. Then the covering layer 2 and the frame layer 16 are placed on the top of the wrapping layer 1, and pressure is applied to them to move downward. Since the card plate 18 and the frame layer 16 are both provided with inclined surfaces of the same angle, the card plate 18 is moved to one side until the card groove 17 on the frame layer 16 moves to the card plate 18, and the card plate 18 is engaged into the card groove 17 under the reaction force of the second return spring 20, so that the covering layer 2 is limited and fixed on the wrapping layer 1.
