The application is described in further detail below with reference to fig. 1-10.
The embodiment of the application discloses a quick-assembly backrest frame, which comprises a frame main body 1, connecting pieces 21 and elastic pieces 9, wherein at least two connecting pieces 21 are arranged on the frame main body 1, the elastic pieces 9 are connected between any two connecting pieces 21, and the connecting pieces 21 are provided with connecting parts 213 for connecting the elastic pieces 9.
In this embodiment, the two connecting pieces 21 are disposed and distributed along the height direction of the frame body 1, so that for convenience of description, the two connecting pieces 21 are respectively referred to as a first connecting piece 211 and a second connecting piece 212, specifically, the first connecting piece 211 is mounted on the top of the frame body 1, and the second connecting piece 212 is mounted on the bottom of the frame body 1, so that the elastic piece 9 can provide a complete supporting effect for the back of the user along the height direction of the frame body 1 after being connected between the two connecting pieces 21, and in this embodiment, the elastic piece 9 adopts a serpentine spring.
In other embodiments, the number of the connection members 21 and the positions of the connection members 21 mounted on the frame body 1 can be customized according to the user's needs, and the elastic members 9 between the connection members 21 can be provided for a specific position of the user's back. Specifically, the connecting members 21 are provided with three or more connecting members 21 in the height direction of the frame body 1, and the elastic member 9 can be connected between any two connecting members 21 according to the user's need.
As for the connection relationship between the connection member 21 and the connection portion 213, referring to fig. 3 to 6, the present application provides the following embodiments:
Example 1
The connecting portion 213 is integrally formed with the connecting member 21, and the common integral forming method is extrusion molding and blow molding, but is not limited to the above two processes, and the connecting portion 213 and the connecting member 21 are generally but not limited to using a profile or plastic material.
In addition, the connecting piece 21 is integrally in a strip shape, and a plurality of connecting portions 213 can be arranged along the length direction of the connecting piece 21 so as to connect a plurality of elastic pieces 9, in this embodiment, after the connecting piece 21 and the connecting portions 213 are integrally formed and produced, a plurality of connecting portions 213 can be punched through a punching process, and the number of the connecting portions 213 and the intervals between the connecting portions 213 can be customized and punched according to the installation requirements of the actual elastic pieces 9.
In this embodiment, the blanking of the connecting portion 213 may be performed on the assembly site, and the position and the number of the connecting portion 213 may be flexibly adjusted, so that the applicability is strong.
Example two
The connecting part 213 and the connecting piece 21 are detachably and fixedly connected, namely, the connecting part 213 and the connecting piece 21 are two independent parts, and can be independently packed and transported before and after disassembly. Specifically, the detachable connection between the connection portion 213 and the connection member 21 may be, but not limited to, joggle, scarf, pre-buried, or bolt connection.
The detachable connection mode generally needs to preset mortises, embedded holes or embedded grooves and the like (not shown) for connection on the connecting piece 21, and can be prefabricated in the factory production process, so that the on-site processing is reduced, and the installation is simpler and more convenient.
Example III
The connecting part 213 and the connecting piece 21 are fixedly connected in a non-detachable mode, namely, the connecting part 213 and the connecting piece 21 are two independent parts before installation, and the connecting part 213 and the connecting piece 21 are not separated after installation or can only be separated in a mode of destroying the connecting structure. Specifically, the common non-detachable connection manner includes welding, bonding, and the like, and it should be noted that the bonding connection is to use solid glue or the like to adhesively connect the connection portion 213 and the connection member 21, and if the glued connection portion 213 is separated from the connection member 21, the solid glue needs to be destroyed, so the bonding manner is also defined as the non-detachable connection manner.
The non-detachable connection mode not only can be used for on-site customized connection, has high installation flexibility and good connection strength, but also can not cause excessive waste on materials of the connecting piece 21 and the connecting part 213.
The different connecting members 21 and the connecting portions 213 thereon may be connected in different connection manners, and in general, in order to facilitate the production and processing, all the connecting members 21 and the connecting portions 213 may be connected in any one of the three embodiments.

In this embodiment, the connecting portion 213 is provided with a through hole 2131 for connecting the end portion of the elastic member 9, the through hole 2131 is in a strip shape, when the elastic member 9 is pressed by the back of the user, the end portion of the elastic member 9 moves along the through hole 2131 to extend the elastic member 9, so as to better fit the back of the user, avoid the concave portion of the elastic member 9, which is pressed by the back of the user, to influence the use experience, and in addition, the connecting portion 213 can be hollowed out for lightening.
In another embodiment, the connecting portion 213 is provided with the through groove 2132, so that the end portion of the elastic member 9 can be directly hung on the connecting portion 213 from the notch of the through groove 2132, the installation is more convenient and quick, and the anti-falling portion 2133 is arranged at the notch, so that the situation that the elastic member 9 is separated from the notch is reduced, and the reliability is improved. It should be noted that the connecting portion 213 needs to have a certain elasticity, when the elastic member 9 is hung in the through groove 2132, the elastic member 9 needs to be pressed to push away the anti-falling portion 2133 to elastically deform until the elastic member 9 is hung in the through groove 2132, and if the elastic member 9 is to be separated from the through groove 2132, the force generated by the elastic deformation of the anti-falling portion 2133 needs to be overcome.
