Abstract
Description
Technical Field
[0001] The utility model relates to a plug-in type backrest chair. Background Art
[0002] The reclining chair with only a base and a backrest has been loved by many users. Its advantage is that it can be placed directly on an ordinary hard board chair, which can improve the comfort of the ordinary hard board chair and has the auxiliary effect of correcting sitting posture and preventing hunchback sitting posture. In the prior art, the reclining chair with only a base and a backrest is made of plastic in one piece. The disadvantage is that the mold is relatively large and the injection molding cost is significantly increased. In addition, since the reclining chair is L-shaped, a larger packaging box is required, and the transportation cost is increased again. Finally, storage will also take up a relatively large packaging box, which makes the overall cost high. Utility Model Content
[0003] In view of the above shortcomings, the utility model provides a plug-in type chair with a backrest, in which a base and a backrest are separately injection-molded, and the user can complete the installation by plugging and unplugging himself, which is convenient for transportation and storage.

[0006] Preferably, the socket structure is provided with a socket side wall, which forms a closed large ring structure, and the plug structure is provided with a plug side wall, which forms one or more closed small ring structures, and the one or more small ring structures can be inserted into the large ring structure.
[0007] Preferably, the outer side of the plug side wall is provided with a plurality of plug vertical grooves, and correspondingly, the inner wall of the socket side wall is provided with a plurality of vertical ribs, which can be inserted into the plug vertical grooves.
[0008] Preferably, the socket side wall is provided with more than one socket transverse reinforcing ribs and a plurality of socket vertical reinforcing ribs, wherein the vertical reinforcing ribs are connected to the vertical convex ribs.
[0009] Preferably, a plurality of base reinforcing ribs are provided on the back side of the base, and the base connecting sections are connected via the base reinforcing ribs.
[0010] Preferably, a plurality of backrest reinforcing ribs are provided on the back side of the backrest, and the backrest connecting sections are connected via the backrest reinforcing ribs.
[0011] Preferably, the base and the backrest are respectively made of plastic in one piece.
[0012] Preferably, the two adjacent small ring structures are connected by a connecting rib.
[0013] Preferably, the plug structure is provided with elastic barbs, and the socket structure is provided with long grooves. When the plug structure is inserted into the socket structure, the elastic barbs can hook the long grooves, thereby hooking and fixing the base and the backrest.
[0014] Compared with the prior art, the utility model has the following advantages:
[0015] By inserting the plug structure into the socket structure, the backrest chair can be separated into two parts, a base and a backrest. The separate base and backrest are easy to produce, the mold requirements are reduced, the overall cost is reduced, the packaging and storage can be reduced in size, and users can assemble them themselves, which greatly reduces the cost.
[0016] The utility model has the beneficial effects of simple structure, low cost, and convenient processing, packaging, transportation and storage. BRIEF DESCRIPTION OF THE DRAWINGS

[0021] Figure 5 for Figure 4 Rear view of . DETAILED DESCRIPTION
[0022] The utility model is now further described in conjunction with the accompanying drawings:
[0023] like Figure 1-Figure 5 As shown, a plug-in chair with an armrest includes a base 1 and a backrest 2, wherein the base 1 is provided with a base connecting section 11, and the backrest 2 is provided with a backrest connecting section 21, the base connecting section 11 is provided with a plug structure, and the backrest connecting section 21 is provided with a socket structure, and the plug structure can be inserted into the socket structure, thereby fixing the base 1 and the backrest 2; and / or, the backrest connecting section 21 is provided with a plug structure, and the base connecting section 11 is provided with a socket structure, and the plug structure can be inserted into the socket structure, thereby fixing the base 1 and the backrest 2.
[0024] In this embodiment, the backrest 2 is provided with a plug, such as Figure 4 As shown, the base 1 is provided with a socket, such as Figure 2 As shown; because the principles are the same, the backrest 2 is provided with a socket, which is omitted from the view, and the base 1 is provided with a plug, which is omitted from the view.
[0025] It should also be noted that the backrest 2 can also be provided with a plug and a socket at the same time, for example, a plug is provided on the left side and a socket is provided on the right side, and correspondingly, a socket is provided on the left side of the base 1 and a plug is provided on the right side.
[0026] The utility model can separate the backrest chair into two parts, a base 1 and a backrest 2, by inserting a plug structure into a socket structure. The separate base 1 and backrest 2 are easy to produce, the mold requirements are reduced, the overall cost is reduced, the packaging and storage can be reduced in size, and users can assemble it themselves, which greatly reduces the cost.
[0027] Preferably, the socket structure is provided with a socket side wall 41, which forms a closed large ring structure, and the plug structure is provided with a plug side wall 31, which forms one or more closed small ring structures. More than one small ring structure can be inserted into the large ring structure, and the closed structure helps to improve the strength.
[0028] In order to improve the strength and better increase the bite force to prevent the plug and the socket from falling off easily, a plurality of plug vertical grooves 34 are provided on the outer side of the plug side wall 31, and correspondingly, a plurality of vertical ribs 42 are provided on the inner wall of the socket side wall 41, which can be inserted into the plug vertical grooves 34.
[0029] In order to improve the strength, the socket side wall 41 is provided with one or more socket transverse reinforcing ribs 44 and a plurality of socket vertical reinforcing ribs 43 , wherein the vertical reinforcing ribs 43 are connected to the vertical convex ribs 42 .
[0030] In order to improve the strength, a plurality of base reinforcing ribs 51 are provided on the back of the base 1 , and the base connecting section 11 is connected via the base reinforcing ribs 51 .
[0031] In order to improve the strength, a plurality of backrest reinforcement ribs 22 are provided on the back of the backrest 2 , and the backrest connecting sections 21 are connected via the backrest reinforcement ribs 22 .
[0032] Preferably, the base 1 and the backrest 2 are respectively made of plastic in one piece.
[0033] Two adjacent small annular structures are connected by connecting ribs 32, and the strength of the annular structure can be improved.
[0034] In order to prevent the assembled base 1 and backrest 2 from automatically separating, the plug structure is provided with an elastic barb 33, and the socket structure is provided with a long groove 40. When the plug structure is inserted into the socket structure, the elastic barb 33 can hook the long groove 40, thereby hooking and fixing the base 1 and the backrest 2. This structure can add a safety factor to ensure that the base 1 and the backrest 2 are firmly fixed.
