In order to achieve the above purpose, the utility model adopts the following technical scheme:

the utility model provides a dismouting structure of chair back, including the cushion with the back that the cushion top set up, the cushion rear end is provided with the connecting plate A that is used for connecting back and cushion, the back bottom is provided with and is used for connecting plate A's connecting plate B, the cushion both ends are provided with the handrail, handrail top end is provided with the bolt hole that is used for connecting back and handrail, the back both ends are provided with the bolt that is used for connecting bolt hole and back.

As the utility model discloses a preferred, still be provided with connecting hole A on the connecting plate A, still be provided with connecting hole B on the connecting plate B, connecting hole A pass through the bolt with connecting hole B connects.

As a preferred aspect of the present invention, the rear end of the armrest is further provided with a mounting edge for connecting the backrest and the armrest.

As the utility model discloses a preferred, the back both ends still are provided with the mounting groove that is used for connecting back and installation limit.

As the utility model discloses a preferred, the installation limit is convex cambered surface, the mounting groove is concave cambered surface, the installation limit can imbed in the mounting groove.

Preferably, a thread is arranged in the connecting hole B.

As the utility model discloses a preferred, the supporting leg passes through the bolt and is connected with the cushion.

As the utility model discloses a preferred, the length of cushion is greater than the length of handrail.

As the utility model discloses a preferred, cushion both ends and handrail bottom junction are the arc.

As the utility model discloses a preferred, the back is the cambered surface of middle part undercut, be undercut arc above the back.

The utility model relates to a dismouting structure of chair back beneficial effect lies in: an object of the utility model is to provide a design is novel, because back and cushion pass through connecting plate A and are connected with connecting plate B, therefore the back can be dismantled, simple to operate.

Because the backrest and the cushion are detachably and separately arranged, the single piece has small weight and is convenient to transport.

Because connecting plate A and connecting plate B pass through bolted connection, have the internal thread that is used for connecting bolt on the connecting hole B on the connecting plate B, the installation limit is convex cambered surface, the mounting groove is concave cambered surface, the installation limit can imbed in the mounting groove, therefore the installation is firm.

Because cushion both ends and handrail bottom junction are the arc, and the back is the cambered surface that the middle part is sunken backward, be sunken arc down above the back, consequently handsome in appearance, the sofa that the back that the comfort level is high can the dismouting.

Detailed Description

The following are specific embodiments of the present invention, and the technical solutions of the present invention are further described, but the present invention is not limited to these embodiments.

Various exemplary embodiments of the present invention will now be described in detail with reference to the accompanying drawings. It should be noted that: the relative arrangement of the modules and structures set forth in these embodiments does not limit the scope of the present invention unless specifically stated otherwise.

The following description of at least one exemplary embodiment is merely illustrative in nature and is in no way intended to limit the invention, its application, or uses.

Techniques, methods, and systems known to those of ordinary skill in the relevant art may not be discussed in detail, but are intended to be part of the specification where appropriate.

The first embodiment is as follows: as shown in fig. 1 to 5, it is only one of them embodiment of the utility model, a dismouting structure of chair back, including cushion 2 with back 1 that cushion 2 top set up, cushion 2 rear end is provided with connecting plate a21 that is used for connecting back 1 and cushion 2, the back bottom is provided with and is used for connecting plate a 21's connecting plate B13, cushion 2 both ends are provided with handrail 3, handrail 3 top is provided with the bolt hole 32 that is used for connecting back 1 and handrail 3, back 1 both ends are provided with the bolt 11 that is used for connecting bolt hole 32 and back 1, simple to operate. The pin 11 and the pin hole 32 play a first reinforcement role.

Connecting plate A21 is located the rear end of cushion 2, and the height of connecting plate A21 is not higher than the height of cushion 2 top surface, and after installation back 1, back 1 can cover connecting plate A21, promotes pleasing to the eye degree. Still be provided with connecting hole A22 on connecting plate A21, still set up connecting hole B14 on connecting plate B13, after laminating connecting plate B13 and connecting plate A21, align connecting hole A22 with connecting hole B14, then through passing the internal threaded connection on connecting hole A22 and the connecting hole B14 to the bolt, it is fixed to connect connecting plate A21 and connecting plate B13, thereby pass through the bolt fastening on cushion 2 with back 1, the bolt plays its first reinforcing effect, stability is stronger, avoid rocking, and simple to operate.

The installation edge 31 is arranged below the bolt hole 32 at the rear end of the armrest 3, and the installation grooves 12 for connecting the backrest 1 and the installation edge 31 are arranged at the two ends of the backrest 1. The installation edge 31 is a convex arc surface, the installation groove 12 is a concave arc surface, the installation edge 31 and the concave arc surface can be matched with each other, and the installation edge 31 can be inserted into the installation groove 12 in an inserting mode. When installation back 1, will laminate the installation limit 31 on installation groove 12 on back 1 and the handrail 3 earlier, then align bolt 11 and bolt hole 32, slide the installation groove 12 of back 1 along installation limit 31 downwards, let in bolt 11 inserts bolt hole 32, fix back 1 bottom on connecting plate A21 with the bolt after a left side, the installation of back 1 and cushion is accomplished.
