Abstract
The utility model relates to a chair, in particular to a public chair convenient to dismantle, which comprises a chair surface, a seat fixedly connected with the side end of the chair surface and a bottom plate fixedly connected with the lower end of the seat, wherein the seat is formed by screwing an upper cylinder with a lower cylinder; a screw hole is arranged in the middle of the upper cylinder; a convex bolt with external thread is fixed in the middle of the lower cylinder; the internal thread of the screw hole is matched with the external thread of the convex bolt; the lower cylinder and the bottom plate are integrated and form an angle of 45 degrees; and two through holes are arranged in the bottom plate. As the seat is formed by screwing the upper cylinder with the lower cylinder, when the chair surface needs to be replaced, the upper cylinder is screwed, then the convex bolt in the middle of the lower cylinder is released from the screw hole of the upper cylinder, and then a new chair surface can be arranged; and the replacement of the whole public chair is not needed, therefore, the maintenance cost is saved. As the lower cylinder and the bottom plate are integrated and form an angle of 45 degrees, the connection is very firm. The public chair is very small and exquisite, and is convenient to transport and install.

Wherein, described seat is that three stairstepping stainless steel tubes constitute.
Wherein, described seat is that three circular arc stainless steel tubes constitute.
Wherein, the circular arc radian of described seat is 270 degree-330 degree.
Compared with prior art, the utility model has the advantages that: 1, the seat of described public chair and seat support can be dismantled, and be easy for installation, is convenient to maintenance and transportation.2, described public chair is small and exquisite nimble, can arbitrarily install according to required space size of putting.

As Fig. 1, Fig. 2, shown in Figure 3, a kind of public chair, seat support 2 of comprise seat 1, fixedlying connected and the base plate 3 of fixedlying connected with seat support 2 lower ends with seat 1 side place, cylinder 22 was spirally connected and forms under described seat support 2 was reached by last cylinder 21, the described cylinder 21 middle places of going up are provided with screw 24, the place is fixed with and is with externally threaded protruding bolt 23 in the middle of the described cylinder 22 down, and the external screw thread of the internal thread of screw 24 and protruding bolt 23 is complementary, and described cylinder 22 down is synthetic with 3 one-tenth miter angle one of base plate.Described base plate 3 is provided with two through holes 4.
Wherein, described seat 1 is that three stairstepping stainless steel tubes constitute.
Wherein, described seat 1 is that three circular arc stainless steel tubes constitute.
Wherein, the circular arc radian of described seat 1 is 270 degree-330 degree.
Because last cylinder 21 and down cylinder 22 be spirally connected and form, if when wanting to change seat, screw cylinder 21, the protruding bolt 23 at place is just unclamped from the screw 24 of last cylinder 21 in the middle of the following cylinder 22, it is just passable to replace with new seat, needn't all change whole public chair, saves maintenance cost.3 one-tenth miter angle one of following cylinder 22 and base plate are synthetic, and are very firm, not frangibility.Base plate 3 is provided with two through holes 4, securing member can be passed through hole 4 base plate 3 arbitrarily is fixed on metope or the ground.Strip on the non-traditional meaning of this kind public chair, but single fixing, very small and exquisite, be convenient to transportation and installation.
Described seat 1 is that three circular arc stainless steel tubes constitute, and its circular arc radian is 270 degree-330 degree.Such design is relatively more novel, allows the people that fresh and new sensation is arranged.
