DETAILED DESCRIPTION

[0021] In order to make the technical problems, technical solutions and beneficial effects solved by the utility model more clearly understood, the utility model is further described below in conjunction with the accompanying drawings and embodiments.

[0022] Example 1

[0023] like Figure 1 As shown, this embodiment provides a sponge-edged spring mattress, including a mattress cover 1, in which a first edge-edged sponge 2, a second edge-edged sponge 3 and a spring layer 4 are arranged, two first edge-edged sponges 2 are arranged along the width direction of the mattress cover 1, and two second edge-edged sponges 3 are arranged along the length direction of the mattress cover 1, both ends of the first edge-edged sponge 2 are provided with rounded corner structures 5, and both ends of the second edge-edged sponge 3 are provided with rounded corner grooves 6 for the rounded corner structures 5 to be inserted, and the spring layer 4 includes a plurality of spring groups 41 with different elastic forces arranged in parallel, and the spring layer 4 is surrounded by the first edge-edged sponge 2 and the second edge-edged sponge 3.

[0024] The first edging sponge 2 and the second edging sponge 3 are connected end to end to form a rectangular edging, and the spring layer 4 is surrounded in the rectangular edging to cushion and protect the constantly deformed spring layer 4. At the same time, the spring layer 4 is composed of spring groups 41 with different elastic forces. The elastic force of multiple positions of the mattress is modularly set to adapt to different user groups and meet the different hardness requirements of two lying positions on a double bed, which is more humane.

[0025] Furthermore, the first edge sponge 2 and the second edge sponge 3 can be fixed to the mattress cover 1 by glue on one side facing away from the spring layer 4. That is, the rectangular edge is glued to the inner wall of the mattress cover 1, and during the use of the mattress, the first edge sponge 2 and the second edge sponge 3 are fixed in position and will not move.

[0026] Furthermore, a comfort pad 7 is provided in the mattress cover 1, and the comfort pad 7 is provided on the spring layer 4, the first edge sponge 2 and the second edge sponge 3. The comfort pad 7 is movable, and the top surface of the mattress cover 1 is detachable by a zipper or the like. When the mattress cover 1 is opened, the comfort pad 7 of different thickness or different material can be replaced, and the manufacturer can customize various types of comfortable mattresses for greater personalization.

[0027] A fixing layer 8 is fixed to the inner bottom surface of the mattress cover 1, and a guide groove 9 is provided on the fixing layer 8. A guide strip 10 that can slide along the guide groove 9 is provided at the bottom of each spring group 41. When assembling the mattress, the mattress cover 1 is first opened, and the three of the first edge sponge 2 and the second edge sponge 3 are interlaced and glued together end to end, and glued to the side wall of the mattress cover 1 at the same time. Then, according to the needs, the guide strip 10 on the spring group 41 is aligned with the guide groove 9 in turn, and gradually slides into the mattress cover 1. When the positions of all the spring groups 41 are determined, the last edge sponge is interlaced with the other edge sponges, and the interlacing can be fixed by glue.

[0028] Of course, the last edge sponge can also be fixed without glue, because the internal size of the mattress cover 1 is fixed. When the three edge sponges and all the spring groups 41 are installed in the mattress cover 1, the mattress cover 1 only leaves a specific position on the horizontal plane of the spring layer 4 for the last edge sponge to be inserted. Because the other structural positions are fixed or limited, and the comfort pad 7 will press on the rectangular edge and the spring layer 4, even if the last edge sponge is not fixed with glue, it will not move when the mattress is used. In addition, when the user needs to adjust the position of different spring groups 41, he only needs to take out the edge sponge that is not glued and fixed to move the spring group 41, which is convenient to operate and more practical.

[0029] Example 2

[0030] like Figure 2 and Figure 3 As shown, this embodiment provides a sponge-bound spring mattress. Based on Embodiment 1, a fixed layer 8 is provided with a plurality of guide grooves 9 along its length direction, and a spring layer 4 is provided with a plurality of guide strips 10 that can slide along the guide grooves 9 at the bottom of its length direction.

[0031] Furthermore, the spring layer 4 has six spring groups 41 , three groups in the length direction of the spring layer 4 and two groups in the width direction of the spring layer 4 , and each spring group 41 is provided with a guide strip 10 at the bottom in the length direction thereof.

[0032] Furthermore, the spring group 41 includes a spring cover 411, a fixing plate 412 and a plurality of independent pocket springs 413. The bottom of the spring cover 411 is provided with a protruding receiving groove 414, the bottom of the fixing plate 412 is provided with a protruding guide strip 10, the fixing plate 412 is fixed to the inner bottom surface of the spring cover 411, the guide strip 10 is fixed in the receiving groove 414, and a plurality of independent pocket springs 413 are evenly fixed on the fixing plate 412.

[0035] Furthermore, the spring layer 4 has six spring groups 41 , three groups in the length direction of the spring layer 4 and two groups in the width direction of the spring layer 4 , and each spring group 41 is provided with a guide strip 10 at the bottom in the width direction thereof.

[0036] Furthermore, the spring group 41 includes a spring cover 411, a fixing plate 412 and a plurality of independent pocket springs 413. The bottom of the spring cover 411 is provided with a protruding receiving groove 414, the bottom of the fixing plate 412 is provided with a protruding guide strip 10, the fixing plate 412 is fixed to the inner bottom surface of the spring cover 411, the guide strip 10 is fixed in the receiving groove 414, and a plurality of independent pocket springs 413 are evenly fixed on the fixing plate 412.
