Description

Technical Field

[0001] This utility model relates to the field of mattress technology, specifically to a multi-layer sponge mattress with shock absorption function. Background Technology

[0002] A mattress is an item placed between the human body and a bed to ensure that consumers get healthy and comfortable sleep.

[0003] Existing multi-layer foam mattresses with shock absorption function have problems in actual use. Because there is no positioning device between the springs in the spring layers, the springs will tilt after a long period of use. This causes the springs to touch each other, resulting in friction when the springs contract, producing a lot of abnormal noise and affecting the user experience. At the same time, because the springs are fixed independently, if one spring is damaged, all the outer springs need to be removed and replaced. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model provides a multi-layer foam mattress with shock absorption function, which has the advantages of limiting the support springs and making it easy to remove and replace the support springs, thus solving the problems mentioned in the background art.

[0005] This utility model provides the following technical solution: a multi-layer sponge mattress with shock absorption function, including a support layer, a sponge layer on top of the support layer, a latex layer on top of the sponge layer, a detachable surface on the outer wall of the support layer, a hook and loop fastener fixedly installed on the outer wall of the support layer, a hook and loop fastener fixedly installed on the outer wall of the detachable surface, a sliding plate slidably connected to the inner wall of the support layer, a limit groove formed on the outer wall of the sliding plate, a limit slider fixedly installed on the inner wall of the support layer, a fixed seat fixedly installed on the top of the sliding plate, a hollow column fixedly installed on the top of the fixed seat, a sliding post slidably connected to the inner wall of the hollow post, a limit plate fixedly installed on the top of the sliding post, a support spring on the outer wall of the hollow post, a sliding groove formed on the outer wall of the hollow post, a tension spring on the inner wall of the sliding post, and a telescopic head slidably connected to the inner wall of the sliding post.

[0006] As a preferred technical solution of this utility model: the shape of the limiting slider is adapted to the inner wall of the limiting groove, and the limiting slider is located on the inner wall of the limiting groove.

[0007] As a preferred technical solution of this utility model: the support spring is located between the limiting plate and the fixed seat, and the diameters of the limiting plate and the fixed seat are both larger than the support spring.

[0008] As a preferred technical solution of this utility model: the diameter of the telescopic head is the same as the width of the inner wall of the slide groove, and the telescopic head is located inside the slide groove.

[0009] As a preferred technical solution of this utility model: the number of the sliding groove, the tension spring and the telescopic head is two, and the two sliding grooves are symmetrically arranged on both sides of the outer wall of the hollow column, and the two tension springs and the telescopic heads are symmetrically arranged on the inner wall of the sliding column.

[0010] As a preferred technical solution of this utility model: the diameter of the sliding column is the same as the diameter of the inner wall of the hollow column, and the part of the sliding column located on the inner wall of the hollow column is in contact with the inner wall of the hollow column.

[0011] Compared with the prior art, the present invention has the following beneficial effects:

[0012] 1. This multi-layered foam mattress with shock absorption function works by pressing down on the support layer, which in turn presses down the limiting plate inside the support layer. This causes the limiting plate to move the sliding column downwards, which in turn presses down on the top of the support spring, causing the support spring to contract. During the contraction and release of the support spring, the hollow column and the sliding column limit the support spring, preventing it from tilting inside the support layer after prolonged use. This prevents adjacent support springs from sticking together and avoids abnormal noises during the contraction of the support spring, thus preventing a poor user experience.

[0013] 2. This multi-layered foam mattress with shock absorption function can be disassembled by removing the outer surface and then pulling the sliding plate outwards, thus removing the sliding plate from the inner wall of the support layer. At this time, press the two telescopic heads, which will move the two telescopic heads towards the inner wall of the sliding column, thereby compressing the tension spring on the inner wall of the sliding column. When the telescopic heads are fully inserted into the interior of the sliding column, the telescopic heads will disengage from the sliding groove. At this time, move the limiting plate upwards, which will cause the limiting plate to move the sliding column upwards, thereby causing the sliding column to move the telescopic heads upwards, thus disengaging the sliding column from the hollow column. At this time, the support spring at the top of the fixing base can be removed and replaced. Attached Figure Description

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0021] Please see Figure 1 - Figure 5 A multi-layered foam mattress with shock absorption function includes a support layer 1, a foam layer 2 on top of the support layer 1, a latex layer 3 on top of the foam layer 2, a detachable surface 4 on the outer wall of the support layer 1, a hook-and-loop fastener 5 fixedly installed on the outer wall of the support layer 1, a hook-and-loop fastener 6 fixedly installed on the outer wall of the detachable surface 4, a sliding plate 7 slidably connected to the inner wall of the support layer 1, a limit groove 8 on the outer wall of the sliding plate 7, a limit slider 9 fixedly installed on the inner wall of the support layer 1, a fixed seat 10 fixedly installed on the top of the sliding plate 7, a hollow column 11 fixedly installed on the top of the fixed seat 10, a sliding column 12 slidably connected to the inner wall of the hollow column 11, a limit plate 13 fixedly installed on the top of the sliding column 12, a support spring 14 on the outer wall of the hollow column 11, a sliding groove 15 on the outer wall of the hollow column 11, a tension spring 16 on the inner wall of the sliding column 12, and a telescopic head 17 slidably connected to the inner wall of the sliding column 12.

[0022] In the above structure, by aligning the disassembly surface 4 with the opening surface of the support layer 1, the hook and loop fastener 1 5 and the hook and loop fastener 2 6 are aligned. Then, the hook and loop fastener 1 5 and the hook and loop fastener 2 6 are bonded together, thereby fixing the support layer 1 and the disassembly surface 4 by the adhesive between the hook and loop fastener 1 5 and the hook and loop fastener 2 6.

[0023] In a preferred embodiment, the shape of the limiting slider 9 is adapted to the inner wall of the limiting groove 8, and the limiting slider 9 is located on the inner wall of the limiting groove 8.

[0024] In the above structure, the limiting groove 8 is limited by the limiting slider 9, so that the limiting groove 8 will not move when it is fixed inside the support layer 1, so that the sliding plate 7 will not move after it is fixed. At the same time, the movement trajectory of the limiting groove 8 is limited, so that the limiting groove 8 will not tilt when it moves, so that the sliding plate 7 will not tilt.

[0025] In a preferred embodiment, the support spring 14 is located between the limiting plate 13 and the fixing seat 10, and the diameters of both the limiting plate 13 and the fixing seat 10 are larger than that of the support spring 14.

[0026] In the above structure, the diameters of the limiting plate 13 and the fixed seat 10 are larger than those of the support spring 14, so that the two ends of the support spring 14 are limited by the limiting plate 13 and the fixed seat 10, thereby preventing the support spring 14 from detaching from the outer wall of the hollow column 11 and the sliding column 12.

[0027] In a preferred embodiment, the diameter of the telescopic head 17 is the same as the width of the inner wall of the groove 15, and the telescopic head 17 is located inside the groove 15.

[0028] In the above structure, the elasticity of the tension spring 16 pushes the telescopic head 17 out toward the outer wall of the sliding column 12, thereby causing the telescopic head 17 to enter the interior of the slide groove 15, thus limiting the telescopic head 17 so that it cannot detach from the slide groove 15, and thus preventing the sliding column 12 from separating from the inner wall of the hollow column 11.

[0029] In a preferred embodiment, there are two slide grooves 15, two tension springs 16 and two telescopic heads 17, with the two slide grooves 15 symmetrically arranged on both sides of the outer wall of the hollow column 11, and the two tension springs 16 and two telescopic heads 17 symmetrically arranged on the inner wall of the sliding column 12.

[0030] In the above structure, by pressing the two telescopic heads 17, the two telescopic heads 17 move towards the inner wall of the sliding column 12, thereby compressing the tension spring 16 on the inner wall of the sliding column 12. When the telescopic heads 17 are fully inside the sliding column 12, the telescopic heads 17 disengage from the slide groove 15. At this time, the limiting plate 13 moves upward, causing the limiting plate 13 to drive the sliding column 12 to move upward, thereby causing the sliding column 12 to drive the telescopic heads 17 to move upward, thereby causing the sliding column 12 to disengage from the hollow column 11. At this time, the support spring 14 at the top of the fixed base 10 can be removed and replaced.

[0031] In a preferred embodiment, the diameter of the sliding column 12 is the same as the inner wall diameter of the hollow column 11, and the portion of the sliding column 12 located on the inner wall of the hollow column 11 is in contact with the inner wall of the hollow column 11.

[0032] In the above structure, the sliding column 12 is attached to the inner wall of the hollow column 11, so that the inner wall of the hollow column 11 limits the sliding column 12, thereby preventing the sliding column 12 from tilting when sliding on the inner wall of the hollow column 11.

[0033] Working Principle: When using this device, the entire device is laid flat on the bed, and the user lies on it. The pressure exerted by the user is transmitted through the latex layer 3 and the sponge layer 2 to the support layer 1. This causes the limiting plate 13 inside the support layer 1 to be pressed downwards. The limiting plate 13 then moves the sliding column 12 downwards, further pressing the top of the support spring 14 downwards, causing the support spring 14 to contract. During the contraction and release of the support spring 14, the hollow column 11 and the sliding column 12 limit the support spring 14, preventing it from tilting inside the support layer 1 after prolonged use. This prevents adjacent support springs from sticking together, causing abnormal noise during the contraction of the support spring 14 and affecting the user experience. Furthermore, if the support spring 14 breaks after prolonged use... Remove the detachment surface 4 and pull the sliding plate 7 outward, thus removing the sliding plate 7 from the inner wall of the support layer 1. At this time, the sliding plate 7 drives several fixed seats 10, hollow columns 11, sliding columns 12, limiting plates 13, support springs 14, slide grooves 15, tension springs 16, and telescopic heads 17 to be removed. Press the two telescopic heads 17, causing them to move towards the inner wall of the sliding column 12, thus compressing the tension springs 16 on the inner wall of the sliding column 12. When the telescopic heads 17 are fully inside the sliding column 12, they disengage from the slide grooves 15. Move the limiting plate 13 upward, causing it to move the sliding column 12 upward, which in turn causes the telescopic heads 17 to move upward, thus disengaging the sliding column 12 from the hollow column 11. At this time, the support spring 14 at the top of the fixed seat 10 can be removed and replaced.

[0034] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
