Some embodiments of the present utility model are described in detail below with reference to the accompanying drawings. Features of the embodiments described below may be combined with each other without conflict.

Example 1

Referring to fig. 1 and 2, an embodiment of a detachable seat structure is disclosed, the detachable seat structure includes a back frame 1, a left side frame 3 and a right side frame 2 in plug-in fit with the back frame 1, plug-in blocks 11 are arranged on two sides of the back frame 1, corresponding slots 22 are arranged on the left side frame 3 and the right side frame 2, and the plug-in blocks 11 on two sides of the back frame 1 are plugged in the slots 22 on the left side frame 3 and the right side frame 2, so that connection and fixation between the three can be realized. The lower part of one end of the left side frame 3 and the right side frame 2 far away from the splicing fit with the back frame 1 is connected with a connecting rod piece 4, the connecting rod piece 4 can be an independent piece according to actual needs or can be an assembly formed by connecting and fixing a first connecting rod 41 and a second connecting rod 42 through a screw 43 after being spliced, when the package is required to be disassembled, the screw 43 can be disassembled, the first connecting rod 41 and the second connecting rod 42 are separated and then packaged, and the package size can be reduced. An upper groove 23 and a lower groove 24 are formed in the side, far away from the right handrail surface 21, of the right side frame 2, an L-shaped connecting end 44 is arranged on the first connecting rod 41, the connecting end 44 is arranged in the lower groove 24, and a bolt 7 downwards penetrates through the right side frame 2 from the upper groove 23 to be connected with a threaded hole 45 of the connecting end 44 so as to fixedly connect the first connecting rod 41 with the right side frame 2. When the package needs to be disassembled, the first link 41 and the right side frame 2 can be separated by simply screwing the bolt 7 out of the screw hole 45. A foot 6 is connected below the first link 41 and the second link 42 for supporting in contact with the ground. The bolts 7 may be either butterfly bolts or hexagonal bolts.

Referring to fig. 2 and 3, support plates are disposed on the first link 41 and the second link 42, and the support plates may be integrally designed or split into a first support plate 51 and a second support plate 52 for saving packaging space, where the first support plate 51 abuts against the first link 41, and the second support plate 52 abuts against the second link 42. The lower part of the back frame 1 is fixedly connected with a support 12, a first convex part 121 is arranged on the support 12, a second convex part 411 is arranged on the first connecting rod 41 and the second connecting rod 42, a first concave part 511 and a second concave part 512 are arranged on the first supporting plate 51 and the second supporting plate 52, the first concave part 511 of the first supporting plate 51 and the second supporting plate 52 are in plug-in fit with the first convex part 121, the second concave part 512 is in plug-in fit with the second convex part 411, the placement stability of the first supporting plate 51 and the second supporting plate 52 can be realized, and the first supporting plate 51 and the second supporting plate 52 are prevented from moving in the using process.

In the above scheme, the structures of the left side frame 3 and the right side frame 2 are the same, so that the left side frame 3 will not be described again.

Referring to fig. 4 and 5, the connection structure of the first link 41 and the right frame 2 is more clearly shown in the sectional view. The first connecting rod 41 is a hollow section bar, a certain wall thickness is reserved between the upper groove 23 and the lower groove 24, the upper groove 23 is provided with enough space so that the bolt 7 can penetrate through the right side frame 2 from the upper groove 23 to be in threaded connection with the first connecting rod 41, and the bolt 7 is positioned inside the first connecting rod 41, so that firm connection can be ensured, and the appearance cannot be influenced by protruding outside. In a specific design, the bolt 7 may also be designed to pass through the first link 41 and then be screwed with the leg 6 to fix the right side frame 2, the first link 41, and the leg 6 together.

Example two

Referring to fig. 6, another structure of the side frame of the detachable seat structure of the present application is different from the embodiment in that the lower groove 24 is omitted, and the structure is simpler.

Example III

Referring to fig. 7 and 8, the present embodiment is different from the first embodiment in that the bracket 12 is rotatably connected to the back frame 1. The support 12 is rotatable within a range of 0 ° to 90 ° relative to the back frame 1, and when the support 12 is rotated to a state of 90 ° relative to the back frame 1, the support 12 cannot continue to rotate, the support 12 forms a stable support surface with the first link 41 and the second link 42, and the first support plate 51 and the second support plate 52 are placed on the support surface. This design allows the stand 12 to be folded during shipping of the package, and does not take up space, resulting in a smaller package size. In order to improve the supporting strength, auxiliary legs are provided under the first and second links 41 and 42, and the number of the specific auxiliary legs may be determined according to the size of the seat, and one leg is provided under each of the first and second links 41 and 42 in the present embodiment.

Example IV

Referring to fig. 9, this embodiment discloses a sofa, which is provided with the detachable seat structure and the integrally and flexibly connected backrest 81, the middle section 82 and the base 83 as described in any one of the embodiments, and the base 83 is abutted against the first support plate 51 and the second support plate 52. When the base 83 and the middle section 82 are folded and the headrest 81 abuts against the back frame 1, a sofa state is formed. The base 83 completely shields the recess from view, so that the recess is not visible from the outside, and thus the aesthetics of the sofa is not affected.

Referring to fig. 10, in order to facilitate the use requirement of the user, an interface 9 is provided on the left side frame 3 or the right side frame 2, and the interface 9 may be a USB interface 9 or a socket.

Referring to fig. 11, when the middle section 82 and the backrest 81 both extend away from the back frame 1 and form a plane with the base 83 in the direction of the armrest surface, a bed state is formed for the user to lie down and rest. The integrated flexible connection of the backrest 81, the middle section 82 and the base 83 is an optimal scheme, in practical application, the backrest 81, the middle section 82 and the base 83 can be designed to be split, and the same function can be realized, but the disadvantage is that relative movement can occur in the use process, so that the use experience is affected.

The foregoing has shown and described the basic principles, principal features and advantages of the utility model. It will be understood by those skilled in the art that the present utility model is not limited to the embodiments described above, and that the embodiments and descriptions described herein are merely illustrative of the principles of the present utility model, and various changes, modifications, substitutions and alterations can be made herein without departing from the spirit and scope of the utility model, which are to be defined by the appended claims.
