A kind of plastic chair

Technical field

The utility model relates to field of furniture, specifically, it is related to a kind of plastic chair.

Background technique

Chair is a kind of daily life furniture, and the chair that general chair is made of cushion and chair leg, while having can also increase Add backrest and handrail to improve comfort.

Authorization Notice No. is that the Chinese utility model patent of CN204410206U discloses a kind of plastic chair, passes through injection molding one It is body formed, including seat plate, the chair back and chair leg, the seat plate is circle, after the chair leg is including two front chair legs and two Chair leg, the chair back include arc-shaped support rod, and the both ends of the support rod are connect with chair leg after two respectively, two preceding chairs Foot is directly anchored on seat plate, and chair leg is fixed by the connecting rod respectively in the edge of seat plate, the extension of the connecting rod after two Line passes through the center of circle of the seat plate, and the angle between the connecting rod is 120~150 degree.

Above-mentioned plastic chair is structurally reasonable, and reliability is higher.But since chair leg length is fixed, and the figure of different people is Difference, therefore the comfort level of the chair of fixed height will be affected for different people.

Utility model content

In view of the deficienciess of the prior art, height is adjustable the purpose of this utility model is to provide a kind of plastic chair, It can be improved the comfort of user.

To achieve the above object, the utility model provides the following technical solutions:

A kind of plastic chair, including chair plate and chair leg；The chair leg includes fixing pipe and regulation pipe, the fixing pipe with it is described Chair plate releasable connection, regulation pipe sliding be threaded through in the fixing pipe and with ground face contact；In the tube wall of the regulation pipe Axis hole is offered, several adjustment hole is provided in the axial direction on the tube wall of the fixing pipe；The fixing pipe with it is described The elastic spacing one of the axis hole and the adjustment hole is provided through between regulation pipe.

So set, can play the role of directly supporting to chair plate after fixing pipe is mounted on chair plate, by that will adjust It is fixed in pipe sliding insertion fixing pipe and using elastic spacing one, so that user can adjust chair according to own situation Highly, to improve comfort level when plastic chair uses；And plastic chair has the characteristics that light weight, corrosion-resistant, intensity is sufficient.

Further setting: the U-shaped sheet setting of elastic spacing one, the elastic spacing one sliding are located at the adjusting In pipe, both ends are abutted with the inner wall of the regulation pipe；Described in being provided in one end of the locating part and outwardly protrude and pass through The short axle of axis hole and the adjustment hole.

So set, regulation pipe is locked in fixing pipe when short axle is also cross axis hole and adjustment hole；It is short when pressing When axis is allowed to be detached from adjustment hole, regulation pipe can be slid in fixing pipe to realize the height adjustment to chair leg.

Further setting: stud ends edge rounded corner.

So set, guiding function is played in the movement that fillet can enter short axle adjustment hole, it is allowed to be more easier to slide Across adjustment hole without being accurately aligned.

Further setting: it is provided in the elastic spacing one far from one end of the short axle and is pasted with the adjusting inside pipe wall The stabilizers of conjunction.

So set, enabling elastic spacing one to be preferably connected to inside regulation pipe by adding stabilizers, avoid It shifts when chair leg height is adjusted.

Further setting: one end of the regulation pipe and ground face contact is provided with the reinforcing edge close to axis.

So set, reinforcing along regulation pipe bottom end can be made not deform when being pressurized, to reinforce the knot of regulation pipe Structure intensity.

Further setting: the chair plate lower end surface setting for the fixing pipe insertion pipe sleeve, the pipe sleeve it is interior Wall is provided with internal screw thread, is provided with external screw thread on the periphery wall of the fixing pipe.

So set, to realize the installation of chair leg, being conveniently replaceable simultaneously by the way that fixing pipe is inserted into pipe sleeve and is screwed.

Further setting: the lower end surface of the chair plate is provided with reinforcing rib, the outer wall of the reinforcing rib and the pipe sleeve Connection.

So set, by adding reinforcing rib, so that guaranteeing that the structure of chair plate is strong in the case where directly not thickening chair plate Degree with higher load-bearing capacity, while keeping lighter weight；Reinforcing rib is connected with pipe sleeve, pipe sleeve can be reduced Deformation when stress improves stability when chair stress.

Further setting: the fixing pipe and the regulation pipe pass through blow molding and form hollow tubular structure.

So set, fixing pipe and regulation pipe is made using blow moulding process, energy under the premise of guaranteeing structural strength The enough weight for further mitigating plastic chair, at the same it is few compared to the clout that injection molding generates, play the role of saving material.

Further setting: the C-shaped setting of elastic spacing one, the elastic spacing one are connected to the interior of the regulation pipe In wall, the both ends of the elastic spacing one are provided with the spindle nose for outwardly protruding and passing through the axis hole and the adjustment hole.

So set, regulation pipe is locked in fixing pipe when two spindle noses are also cross axis hole and adjustment hole；When pressing When two spindle noses being pressed to be allowed to be detached from adjustment hole, regulation pipe can be slid in fixing pipe to realize the height adjustment to chair leg.

Further setting: the bottom of the regulation pipe is provided with neonychium.

So set, neonychium can prevent the bottom of regulation pipe from directly contacting bottom surface and causing to wear.

In conclusion the utility model has the following beneficial effects:

1. user can be according to their needs by adjusting chair leg length to change chair height, to improve sitting posture Comfort；

2. plastic chair is light-weight, structural strength is higher, has good bearing capacity.
