[0086] It should be understood that, in some other embodiments, the snap block 230 is provided with three or more snap slots 232 , which can serve as support points for the connection of the connector 220 to assist in achieving the connection and fixation between the connector 220 and the snap block 230 .

[0087] It is understandable that in this embodiment, the sofa also includes two wear-resistant plates, one of which is sandwiched between the lower end of the spring body 140 and the bottom wall of the bag body 130, thereby improving the connection stability between the spring body 140 and the bag body 130, and helping to reduce the mutual slippage between the lower end of the spring body 140 and the bottom wall of the bag body 130.

[0088] Reference Figure 1 、 Figure 2 and Figure 3 As shown, another wear-resistant sheet is connected between the upper end of the spring body 140 and the gasket to improve the connection stability between the spring body 140 and the gasket, which is beneficial to reduce the mutual slippage between the upper end of the spring body 140 and the gasket. The wear-resistant sheet has wear-resistant physical properties and can effectively reduce the risk of material powdering after long-term use, thereby improving the durability of the sofa.

[0089] Reference Figure 1 、 Figure 2 and Figure 3 As shown, specifically, the wear-resistant sheet can be a blended material of polyester fiber and fiber, as well as various materials with high wear resistance.

[0090] It should be understood that in some other embodiments, the sofa further includes a second pull-shaped strip, which is connected to the inner surface of the outer shell, and the second pull-shaped strip is embedded in the junction of two adjacent backrests 110, and the second pull-shaped strip is connected to multiple connectors 220 and multiple fasteners. The production personnel can connect one end of the connector 220 to the second pull-shaped strip, and then connect the other end of the connector 220 to the needle body, and pass the needle body horizontally through the backrest 110, so that the other end of the connector 220 passes through the backrest 110. After removing the needle body from the other end of the connector 220, the other end of the connector 220 can be connected to the fastener, and the fastener can abut against the outer side of the backrest 110, thereby tightening the second pull-shaped strip, so that the second pull-shaped strip is embedded between the two adjacent backrests 110, so that the outer shell forms a fold between the two adjacent backrests 110, thereby improving the fit between the outer shell and the seat 100.

[0091] It is understandable that in this embodiment, it is understandable that the sofa also includes glue-free cotton. After the bag body 130, the spring body 140, the seat body 120 and the backrest 110 are assembled into the seat body 100, the production personnel can stick a layer of glue-free cotton on the upper end of the seat body 100. The glue-free cotton can cover the joints of the bag body 130, the spring body 140, the seat body 120 and the backrest 110. Through the fitting of the glue-free cotton, the tactile feel provided by the seat body 100 to the user can be improved, thereby reducing the sense of separation produced at the joints of the bag body 130, the spring body 140, the seat body 120 and the backrest 110.

[0092] That is, the glue-free cotton is sandwiched between the upper end of the base 100 and the outer cover. The glue-free cotton is a cotton layer that does not contain glue, which can avoid the problem of glue emitting bad odor.

[0093] Reference Figures 8 to 13 As shown, a production process according to an embodiment of the present invention is used to produce a sofa as shown in any of the above embodiments, and the production process includes the following steps:

[0094] Step S100: assembling a plurality of vertical springs 141 into a spring body 140 according to product design, wherein the plurality of vertical springs 141 are arranged in a plane, and the sides of the plurality of vertical springs 141 are connected to each other;

[0095] Step S200: insert the lower end of the spring body 140 into the bag body 130 and connect the spring body 140 to the bag body 130;

[0096] Step S300: Attaching a cotton body to the upper end of the spring body 140 to form the seat body 120 and the backrest body 110. The spring body 140, the bag body 130, the seat body 120, and the backrest body 110 together constitute the seat body 100. The backrest body 110 is adjacent to the seat body 120 for supporting the back or hands of the human body.

[0097] In step S400 , the outer cover is covered on the outer side of the base 100 so that the inner surface of the cover fits the outer surface of the base 100 .

[0098] Reference Figure 1 、 Figure 2 and Figure 8 As shown, in step S100, the production personnel can combine multiple vertical springs 141 into a spring body 140 according to the product design. For example, the product design requires combining 12 rows of vertical springs 141 into one body, with each row of vertical springs 141 having 13 vertical springs 141, that is, the spring body 140 is a 12*13 combination pattern. The multiple vertical springs 141 are arranged in a plane, and the sides of the multiple vertical springs 141 are connected to each other.

[0099] Reference Figure 1 、 Figure 2 and Figure 8 As shown, specifically, each row of vertical springs 141 includes a plurality of bagged springs connected to each other, and two adjacent rows of vertical springs 141 can be bonded by hot melt adhesive to achieve fixation of the two adjacent rows of vertical springs 141, so that the multiple vertical springs 141 are combined into a whole, so as to improve the connection stability of the multiple vertical springs 141, and enable subsequent combination or processing on the spring body 140.

[0100] Reference Figure 1 、 Figure 2 and Figure 8 As shown, in step S200 , the production personnel may sleeve the lower end portion of the spring body 140 into the bag body 130 and connect the spring body 140 to the bag body 130 to achieve relative fixation of the spring body 140 and the bag body 130 .

[0101] Reference Figure 1 、 Figure 2 and Figure 8 As shown, in traditional processes, workers need to cut sponge sheets according to the size of the seat cushion and splice them together to surround the lower end of the seat cushion, thereby reducing the foreign body sensation caused by the internal support base for the user. The bag body 130 of the production process provided by the embodiment of the present invention has a accommodating cavity 131 with an upward opening. The lower end of the spring body 140 is sleeved within the accommodating cavity 131, thus wrapping the lower end of the spring body 140, thereby reducing the foreign body sensation caused by the spring body 140 for the user. The bag body 130 can cover the lower end of the spring body 140, which is beneficial to improving the production efficiency of sofas.

[0102] Reference Figure 1 、 Figure 2 and Figure 8As shown, specifically, the production process can be formed into a bag body 130 by sewing the pleated fabric. After the lower end of the spring body 140 is directly placed in the bag body 130, the bag body 130 can cover the lower end of the spring body 140. The bag body 130 has a certain thickness and cushioning performance after the pleating, which can effectively reduce the foreign body sensation caused by the spring body 140 to the user, can effectively simplify the production process, and improve the production efficiency of the sofa.

[0103] Reference Figure 1 、 Figure 2 and Figure 8 As shown, in step S300, the upper end of the spring body 140 is formed with a seat 120 and a backrest 110. The seat 120 is used to provide a comfortable sitting feeling for the user, and the backrest 110 is arranged beside the seat 120 to support the back or hands of the human body.

[0104] Reference Figure 1 、 Figure 2 and Figure 8 As shown, in step S400, the outer cover is wrapped around the base 100 from top to bottom to achieve the connection between the outer cover and the base 100. The outer cover is wrapped around the outer side of the base 100 to cover the outer surface of the base 100, so as to hide the connection between the bag body 130, the spring body 140, the seat body 120 and the backrest body 110. The outer cover can serve as the fabric that comes into contact with the user.

[0105] Reference Figure 1 、 Figure 2 and Figure 9 As shown, it can be understood that the production process, in step S200, sleeves the lower end of the spring body 140 into the bag body 130, and connects the spring body 140 to the bag body 130, including the following steps:

[0106] Step S210: Sewing the fabric into a bag 130 with an upward opening, and inserting the lower end of the spring 140 into the bag 130;

[0107] Step S220: Connect multiple fasteners around the upper edge of the bag body 130, and connect the bag body 130 and the spring body 140 with the fasteners.

[0108] Reference Figure 1 、 Figure 2 and Figure 9 As shown, in step S210, the production personnel can obtain a sheet material for producing the bag body 130 by pleating and cutting. Then, notches are cut at the four edges of the sheet material, and two adjacent edges of the notches are connected to each other by sewing, so that the sheet material forms a bag body 130 with an upward opening. The size of the sheet material and the size of the notches can be designed according to the size of the lower end of the spring body 140 and are not limited here.

[0109] Reference Figure 1 、 Figure 2 and Figure 9 As shown, in step S220, the assembler can connect multiple fasteners at the upper edge of the bag body 130 by nailing or fastening, so that the fasteners at least partially pass through the upper edge of the bag body 130 and the side wall of the spring body 140, thereby achieving relative fixation of the upper edge of the bag body 130 and the side wall of the spring body 140, which is beneficial to improving the connection stability between the bag body 130 and the spring body 140.

[0110] Reference Figure 1 and Figure 2 As shown, it can be understood that the production process in step S200 includes the following steps:

[0111] Reference Figure 1 and Figure 2 As shown, one layer of the wear-resistant sheet is stacked on the bottom wall of the accommodating cavity 131 of the bag body 130, and then the lower end of the spring body 140 is sleeved in the bag body 130, that is, one layer of the wear-resistant sheet is sandwiched between the lower end of the spring body 140 and the bottom wall of the accommodating cavity 131, thereby improving the connection stability between the spring body 140 and the bag body 130, and helping to reduce the mutual slippage between the lower end of the spring body 140 and the bottom wall of the bag body 130.

[0112] Reference Figure 1 and Figure 2 As shown, another layer of wear-resistant sheet and sitting sponge are stacked from bottom to top on the upper end of the spring body 140, so that the other layer of wear-resistant sheet is sandwiched between the spring body 140 and the gasket, so as to improve the connection stability between the spring body 140 and the gasket, which is beneficial to reduce the mutual slippage between the upper end of the spring body 140 and the gasket. The wear-resistant sheet has wear-resistant physical properties, which can effectively reduce the risk of material pulverization after long-term use, thereby improving the durability of the sofa.

[0113] Reference Figure 1 and Figure 2 As shown, the seat body 100 also includes a sitting sponge, which is laid on the upper end of the wear-resistant plate at the upper end of the spring body 140. The sitting sponge is used to improve the sitting feel of the sofa and improve the user's comfort.

[0114] Reference Figure 1 、 Figure 2 and Figure 10 As shown, it can be understood that the cotton body includes a gasket and a surrounding block, the gasket includes a lower piece 121, a middle piece 122 and an upper piece 123, and the upper surface of the spring body 140 is arranged in a plane.

[0115] In step S300, the production process includes the following steps: attaching a cotton body to the upper end of the spring body 140 to form the seat body 120 and the back body 110 on the upper end of the spring body 140;

[0116] Step S310 , connecting the lower piece 121 to the upper surface of the spring body 140 , and connecting the surrounding block to the upper surface of the lower piece 121 to form the backrest 110 ;

[0117] Step S320, connect the middle piece 122 and the upper piece 123 in sequence on the upper surface of the lower piece 121, the outer edge of the upper piece 123 and the outer edge of the lower piece 121 are both located outside the outer edge of the middle piece 122 to form the seat 120, and the backrest 110 is arranged around the seat 120.

[0118] Reference Figure 1 、 Figure 2 and Figure 10 As shown, in step S310, production personnel can fix the surrounding blocks to the upper surface of the lower piece 121 according to product design requirements. The surrounding blocks can be made of high-density sponge to provide strong support for the user's hands or back. Specifically, two surrounding blocks are provided, and the two surrounding blocks are arranged at right angles to form two backrests 110. The area enclosed by the two backrests 110 can be used for the user to sit on.

[0119] Reference Figure 1 、 Figure 2 and Figure 10 As shown, in step S320, the production personnel can sequentially stack the middle piece 122 and the upper piece 123 on the upper end of the lower piece 121, and make the middle piece 122 and the upper piece 123 located between the two backrests 110 to form a seat 120 for the user to sit on. The outer edge of the upper piece 123 and the outer edge of the lower piece 121 are both located outside the outer edge of the middle piece 122, that is, the area of the middle piece 122 is smaller than the area of the upper piece 123 and the lower piece 121, so that a gap is formed between the outer edge of the upper piece 123 and the outer edge of the lower piece 121. When the upper piece 123, the middle piece 122 and the lower piece 121 are pressed tightly, the outer edge of the upper piece 123 has a downward curvature, thereby improving the comfort of the user's legs contacting the edge of the seat 120.

[0120] It should be understood that in some other embodiments, the cotton body includes a gasket and multiple buffer pads, the gasket includes a lower piece 121, a middle piece 122 and an upper piece 123; the spring body 140 includes a seat 142 and a leaning portion 143, the leaning portion 143 is arranged around the seat 142, and the upper end of the leaning portion 143 is located above the upper end of the seat 142; the spring body 140 includes multiple first springs and multiple second springs, and the height of the first spring is higher than the height of the second spring.

[0121] Reference Figure 7 As shown, in step S100, the production process combines multiple vertical springs 141 into a spring body 140 according to the product design. The multiple vertical springs 141 are arranged in a plane, and the sides of the multiple vertical springs 141 are connected to each other. The process includes the following steps:

[0122] The side portions of the plurality of second springs are connected to each other to form a seat portion 142, and the upper end surface of the seat portion 142 is flat;

[0123] A plurality of first springs are disposed around the seat portion 142 to form a leaning portion 143 surrounding the seat portion 142 .

[0124] Reference Figure 7 As shown, this production process can utilize a first spring and a second spring of different heights to assemble, with the upper end of the taller first spring forming the support portion 143, and the upper end of the shorter second spring forming the seat portion 142. This means that the spring body 140 can not only serve as a support base for the seat 120, but can also extend upward and serve as a support base within the backrest 110. The production process provided by this embodiment of the present invention allows the spring body 140 to be assembled in such a way that it extends into the interior of the backrest 110, thereby providing strong support for the user's hands and back.

[0125] Reference Figure 1 、 Figure 2 and Figure 11 As shown, in step S300, the production process is to attach a cotton body to the upper end of the spring body 140 so that the upper end of the spring body 140 is formed into the seat body 120 and the back body 110, including the following steps:

[0126] Step S330 , attaching a plurality of cushioning pads around the upper end of the support portion 143 to form the support body 110 ;

[0127] In step S340, the lower piece 121, the middle piece 122 and the upper piece 123 are sequentially attached to the upper end of the seat 142, and the outer edges of the upper piece 123 and the lower piece 121 are both located outside the outer edge of the middle piece 122 to form the seat 120.

[0128] Reference Figure 1 、 Figure 2 and Figure 11 As shown, in step S330, the production personnel can fit multiple buffer pads on the upper side and surrounding side of the backrest 143, that is, fit multiple buffer pads around the upper end of the first spring to form the backrest 110. The buffer pads can reduce the foreign body sensation caused by the first spring to the user, and the upper end of the first spring can serve as a supporting base for the backrest 110.

[0129] Reference Figure 1 、 Figure 2 and Figure 11As shown, in step S340, the lower sheet 121, the middle sheet 122, and the upper sheet 123 are sequentially attached to the upper end of the seat portion 142, that is, the gasket is connected to the upper portion of the seat portion 142, thereby forming the seat body 120. The outer edges of the upper sheet 123 and the lower sheet 121 are both located outside the outer edge of the middle sheet 122. In other words, the area of the middle sheet 122 is smaller than the areas of the upper sheet 123 and the lower sheet 121, so that a gap is formed between the outer edges of the upper sheet 123 and the lower sheet 121. When the upper sheet 123, the middle sheet 122, and the lower sheet 121 are pressed tightly together, the outer edge of the upper sheet 123 has a downward curvature, thereby improving the comfort of the user's legs contacting the edge of the seat body 120.

[0130] The production process further includes the following steps in step S400:

[0131] Connect the second pull-shaped strip to the inner surface of the outer shell, and connect one end of the connector 220 to the second pull-shaped strip;

[0132] The other end of the connector 220 connected to the second pull-shaped strip passes through the base 100 , and then the other end of the connector 220 is connected to the buckle, thereby tightening the second pull-shaped strip so that the second pull-shaped strip is embedded between two adjacent leaning bodies 110 .

[0133] The sofa also includes a second pull-shaped strip, which is connected to the inner surface of the outer shell and is embedded in the junction of two adjacent backrests 110. The second pull-shaped strip is connected to multiple connectors 220 and multiple snap fasteners. The production personnel can connect one end of the connector 220 to the second pull-shaped strip, and then connect the other end of the connector 220 to the needle body, and pass the needle body horizontally through the backrest 110, so that the other end of the connector 220 passes through the backrest 110. After removing the needle body from the other end of the connector 220, the other end of the connector 220 can be connected to the snap fastener, and the snap fastener can abut against the outer side of the backrest 110, thereby tightening the second pull-shaped strip, so that the second pull-shaped strip is embedded between the two adjacent backrests 110, so that the outer shell forms a fold between the two adjacent backrests 110, thereby improving the fit between the outer shell and the seat 100.

[0134] It can be understood that in this embodiment, after the bag body 130, the spring body 140, the seat body 120 and the backrest 110 are assembled into the seat body 100, the production process can stick a layer of glue-free cotton on the upper end of the seat body 100. The glue-free cotton can cover the joints of the bag body 130, the spring body 140, the seat body 120 and the backrest 110. Through the fitting of the glue-free cotton, the tactile feel provided by the seat body 100 to the user can be improved, thereby reducing the sense of separation produced at the joints of the bag body 130, the spring body 140, the seat body 120 and the backrest 110.

[0135] Reference Figure 5 、 Figure 6and Figure 12 As shown, it can be understood that, in this embodiment, the production process in step S400, in which the outer cover is covered on the outer side of the base body 100 so that the inner surface of the outer cover is in contact with the outer surface of the base body 100, includes the following steps:

[0136] Step S410: Wrap the outer cover around the base 100, connect one end of the connector 220 to the cover, connect the other end of the connector 220 to the needle, and insert the needle through the base 100, so that the connector 220 is installed through the base 100.

[0137] In step S420 , the other end of the connector 220 is separated from the needle body and connected to the fastener. The fastener abuts against the outer side of the base 100 to tighten the outer cover so that the outer cover fits the outer surface of the base 100 .

[0138] Reference Figure 5 、 Figure 6 and Figure 12 As shown, in step S410, the production personnel can initially cover the outer side of the base body 100 with the outer sleeve, connect one end of the connector 220 to the inner side of the outer sleeve, connect the other end of the connector 220 to the needle body, and pass the needle body through the base body 100, so that the two ends of the connector 220 are respectively located at the two ends of the back of the base body 100, so that the connector 220 is set through the base body 100.

[0139] Reference Figure 5 、 Figure 6 and Figure 12 As shown, in step S420, the production personnel can separate the other end of the connector 220 from the needle body and withdraw the needle body from the base 100, so that the other end of the connector 220 is connected to the fastener, that is, the other end of the connector 220 is retained on the outside of the base 100 through the fastener, and the fastener abuts against the outside of the base 100 to tighten the coat so that the coat is tightly attached to the outer surface of the base 100, thereby improving the fit between the coat and the base 100 and enhancing the styling of the sofa. In addition, through the positioning of the connector 220, the matching stability of the coat and the base 100 can be improved, thereby reducing the offset between the coat and the base 100.

[0145] Reference Figure 5 、 Figure 6 and Figure 13 As shown, in step S411 , the production staff may connect the first pull-shaped strip 210 to the inner side of the outer jacket, and then tie one end of the connector 220 to the first pull-shaped strip 210 .

[0146] Reference Figure 5 、 Figure 6 and Figure 13 As shown, in step S421, the production personnel can tie the other end of the connecting piece 220 to the needle body, pass the needle body through the seat body 100 from top to bottom, so that the other end of the connecting piece 220 passes through the seat body 100. After removing the needle body from the other end of the seat body 100, the other end of the connecting piece 220 can be passed through the through hole 231 of the snap block 230, and then the snap block 230 is pressed against the end of the seat body 100 facing away from the seat body 120, and then the connecting piece 220 is wrapped around the two slots 232 for multiple turns, so that the connecting piece 220 is embedded in the slot 232 to achieve the fixation of the other end of the connecting piece 220 and the snap block 230, so that the first pull-shaped strip 210 is embedded in the junction of the seat body 120 and the back body 110, so that the outer coat forms a fold at the junction of the seat body 120 and the back body 110, thereby improving the fit between the outer coat and the seat body 100.

[0147] This production process allows the connector 220 to pass through the bottom end of the bag body 130 and abut against the bottom surface of the bag body 130 through the snap block 230, thereby assisting in positioning and fixing the bag body 130 and the base body 100.
