Utility model content
The purpose of this utility model is the above problem overcoming prior art existence, more reliability is high, fault is low, it is low to rotate use dynamics to provide one to rotate, can the more simply light rotation underframe for public chair of fixed position, structure, it can overcome the fault of existing underframe problem occurred frequently, reduces maintenance cost.
For realizing above-mentioned technical purpose, reach above-mentioned technique effect, the utility model is achieved through the following technical solutions:
For a rotation underframe for public chair, comprise the lower underframe and upper underframe that are connected by hollow rotating disk, described lower underframe is connected with described hollow rotating disk by lower rotary table gripper shoe, and described upper underframe is connected with described hollow rotating disk by top rotary table gripper shoe; Described erection of going to the bottom is equipped with footstep mechanism, and footstep mechanism is connected with the first roller, and described first roller is arranged at described lower underframe side;
Described upper underframe is the frame structure that the handrail link of a pair main stay pipe and both sides thereof is formed, and main stay pipe is connected with central bracket, is connected to a leading truck, leading truck is provided with the second roller bottom described handrail link.
Preferably, described lower chassis top surface is provided with lower draw runner, and described lower draw runner is provided with a pair, lays respectively at lower underframe both sides.
Further, the batter that described footstep mechanism comprises foot-operated spring and is connected to foot-operated spring one end is stepped on, and described batter is stepped on and is arranged at described lower underframe side.
Preferably, described lower underframe both sides of the edge are connected with lower underframe guide plate.
The beneficial effects of the utility model are:
This underframe is lightweight construction underframe, and lightweight, structural strength is high.Main body is divided into upper and lower two parts, and frame body of going to the bottom, by welding fabrication, makes its weight reduce, lower underframe maintains static, and the center of upper and lower underframe is connected by hollow rotating disk, limited location structure on underframe, therefore go up underframe and come and go rotation 180 ° only, this underframe achieves rotatable function thus.Limited location lockable mechanism on underframe, after upper underframe rotates 180 °, automatic locking is fixed, and prevents underframe axial rotation.Underframe is provided with rollover-resistant mechanism, and prevent underframe overall rollover because of single load bearing, destruction center's rotating mechanism, damages underframe.
Above-mentioned explanation is only the general introduction of technical solutions of the utility model, in order to better understand technological means of the present utility model, and can be implemented according to the content of description, coordinates accompanying drawing to be described in detail as follows below with preferred embodiment of the present utility model.Detailed description of the invention of the present utility model is provided in detail by following examples and accompanying drawing thereof.

Detailed description of the invention
Below with reference to the accompanying drawings and in conjunction with the embodiments, describe the utility model in detail.
Shown in Figure 10, a kind of rotation underframe for public chair, comprise the lower underframe 1 and upper underframe 2 that are connected by hollow rotating disk 6, described lower underframe 1 is connected with described hollow rotating disk 6 by lower rotary table gripper shoe 3, and described upper underframe 2 is connected with described hollow rotating disk 6 by top rotary table gripper shoe; Described lower underframe 1 is provided with footstep mechanism 4, and footstep mechanism 4 is connected with the first roller 16, and described first roller 16 is arranged at described lower underframe 1 side;
Described upper underframe 2 is the frame structure that the handrail link 9 of a pair main stay pipe 7 and both sides thereof is formed, and main stay pipe 7 is connected with central bracket 10, is connected to a leading truck 8 bottom described handrail link 9, leading truck 8 is provided with the second roller 11.
Described lower underframe 1 upper surface is provided with lower draw runner 5, and described lower draw runner 5 is provided with a pair, lays respectively at lower underframe 1 both sides.The batter that described footstep mechanism 4 comprises foot-operated spring 14 and is connected to foot-operated spring 14 one end steps on 15, and described batter is stepped on 15 and is arranged at described lower underframe 1 side.Described lower underframe 1 both sides of the edge are connected with lower underframe guide plate 13.
Lower underframe 1 maintains static, and the center of upper and lower underframe is connected by hollow rotating disk 6, limited location structure on lower underframe 1, and position-limit mechanism is made up of footstep mechanism 4 and leading truck 8.Upper underframe 2 comes and goes rotation 180 ° only, and when arrival 180 °, footstep mechanism 4 and leading truck 8 locking, prevent underframe axial rotation.This underframe achieves the function of rotatable function and spacing locking thus.Underframe is provided with rollover-resistant mechanism, is made up of leading truck 8 and lower underframe guide plate 13.After upper underframe 2 rotates 180 °, the second roller 11 blocks leading truck 8, and prevent underframe 2 overall rollover because of single load bearing, destruction center's rotating mechanism, damages underframe.Pedal power given by foot-operated spring 14, makes batter step on 15 and can automatically stick in the groove of leading truck 8.
