The utility model realizes that technical solution used by its technical purpose is:
A kind of Lumbar structure being easily installed, including the chair back, Lumbar part and at least one mounting base, the mounting base are solid
Fixed to be arranged on the chair back, the mounting base is equipped with sliding slot；The Lumbar part include Lumbar ontology and by Lumbar ontology in the middle part of
The clamping portion extended, the clamping portion are correspondingly arranged with mounting base, and the clamping portion and sliding slot slide up and down cooperation.
Preferably, the mounting base is respectively arranged on the left side and the right side two sliding slots, the mounting base is equipped with and left and right
The slot of two side chutes connection；The clamping portion two sides are respectively at least provided with two positioning protrusion, the positioning protrusion and sliding slot
Cooperation is slided up and down, one is equipped in the middle part of the clamping portion convenient for the clamping portion groove that inwardly deformation occurs；When installation, clamping portion to
Slot is inserted into interior generation elastic deformation, restores deformation after clamping portion insertion slot, the positioning protrusion of two sides is installed in sliding slot.
Preferably, the groove includes inner groovy and external groove, the section of the inner groovy is triangle, described outer recessed
The section of slot is rectangle.Convenient for the inside extruding of groove.
Preferably, the mounting base is that mounting base described in two, two is symmetricly set in the chair back lower position.
Preferably, the clamping portion two sides are respectively equipped with two positioning protrusion, the positioning protrusion is cylindrical body.It is convenient for
Lumbar slides up and down in sliding slot, reduces the contact area between positioning protrusion and sliding slot, reduces frictional force when Lumbar sliding.
Further, the end of the positioning protrusion is equipped with chamfering.It is snapped fits into sliding slot convenient for clamping portion.
Preferably, the Lumbar ontology is in the arc setting being bonded with human body waist.
The beneficial effects of the utility model are:
The utility model realizes the Fast Installation of Lumbar part using the elasticity of clamping portion.
Specifically, can enabling clamping portion, inwardly deformation occurs, and at the same time, after slot is inserted into clamping portion, clamping portion is restored
After deformation, the positioning protrusion of two sides is installed in sliding slot.
The utility model does not need that installation can be realized using parts such as additional plastic, screw, self threading pins.Easy peace
The step of dress, reduces the possibility that worker installs error, improves the quality and efficiency of production.

Specific embodiment
The technical solution of the utility model is described in further detail below by specific embodiment and in conjunction with attached drawing.
As shown in figs. 1-7, a kind of Lumbar structure being easily installed, including the chair back 1, Lumbar part 2 and two mounting bases 3,
The mounting base 3 is fixed on the chair back 1, corresponding human body waist position.The mounting base 3 is equipped with sliding slot 31；The waist
Lever 2 includes Lumbar ontology 21 and the clamping portion 22 by extending in the middle part of the Lumbar ontology 21, the clamping portion 22 and mounting base 3
It is correspondingly arranged, the clamping portion 22 slides up and down cooperation with sliding slot 31.
Specifically, as shown in Fig. 2, the mounting base 3 is respectively arranged on the left side and the right side two sliding slots 31, the mounting base 3
It is equipped with the slot 32 being connected to left and right sides sliding slot 31；22 two sides of clamping portion are respectively equipped with two positioning protrusion 23, institute
Stating positioning protrusion 23 is cylindrical body, and slides up and down cooperation with sliding slot 31.It is equipped with one in the middle part of the clamping portion 22 and is convenient for clamping portion
22 grooves 24 that inwardly deformation occurs.When installation, clamping portion 22 inwardly occurs elastic deformation and is inserted into slot 32, and clamping portion 22 is inserted into
Restore deformation after slot 32, the positioning protrusion 23 of two sides is installed in sliding slot 31.For the ease of being caught in for positioning protrusion 23, institute
The end for stating positioning protrusion 23 is equipped with chamfering.
As shown in figure 5, the groove 24 includes inner groovy 241 and external groove 242, the section of the inner groovy 241 is three
Angular, the section of the external groove 242 is rectangle.
