Description
Technical field
The present invention relates to public chair field, in particular to a kind of rotation underframe for public chair that is applicable to the fields such as train, theater, meeting-place, aviation.
Background technology
Recent years, the public chair development of China was swift and violent, needed seat can realize the function of Rotate 180 ° in some fields, will guarantee security and the comfortableness of seat simultaneously.Seat rotation underframe function in existing same domain is unsound, and fault is occurred frequently, and maintenance cost is high.For reducing fault, and make seat rotation more comfortable light, this underframe is given birth to because of fortune.
Summary of the invention
The object of the invention is to overcome the above problem that prior art exists, a kind of rotation is provided, and more reliability is high, fault is low, rotation use dynamics is low, can fixed position, the more simple light rotation underframe for public chair of structure, it can overcome the fault problem occurred frequently of existing underframe, has reduced maintenance cost.
For realizing above-mentioned technical purpose, reach above-mentioned technique effect, the present invention is achieved through the following technical solutions:
For a rotation underframe for public chair, comprise the lower underframe and the upper underframe that by hollow rotating disk, are connected, 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 go to the bottom to set up be equipped with footstep mechanism, footstep mechanism is connected with the first roller, described the first roller is arranged at described lower underframe one side;
Described upper underframe is the frame structure that the handrail link of a pair of main stay pipe and both sides thereof forms, and main stay pipe is connected with central bracket, and described handrail link bottom is connected with respectively a leading truck, is provided with the second roller on leading truck.
Preferably, described lower chassis top surface is provided with lower draw runner, and described lower draw runner is provided with a pair of, 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 one side.
Preferably, described lower underframe both sides of the edge are connected with lower underframe guide plate.
The invention has the beneficial effects as follows:
This underframe is lightweight construction underframe, lightweight, and structural strength is high.Main body is divided into upper and lower two parts, and the frame body of going to the bottom, by welding fabrication, makes its weight reducing, lower underframe maintains static, and the center of upper and lower underframe is connected by hollow rotating disk, limited location structure on underframe, therefore upper underframe comes and goes Rotate 180 ° only, and this underframe has been realized rotatable function thus.Limited location lockable mechanism on underframe, after upper underframe Rotate 180 °, automatic locking is fixed, and prevents underframe axial rotation.Underframe is provided with rollover-resistant mechanism, prevents that underframe is because of the whole rollover of single load bearing, and destruction center's rotating mechanism, damages underframe.
Above-mentioned explanation is only the general introduction of technical solution of the present invention, in order to better understand technological means of the present invention, and can be implemented according to the content of description, below with preferred embodiment of the present invention and coordinate accompanying drawing to be described in detail as follows.The specific embodiment of the present invention is provided in detail by following examples and accompanying drawing thereof.

The specific embodiment
Below with reference to the accompanying drawings and in conjunction with the embodiments, describe the present invention in detail.
Shown in Figure 10, a kind of rotation underframe for public chair, comprise the lower underframe 1 and the upper underframe 2 that by hollow rotating disk 6, are connected, 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 the first roller 16 is arranged at described lower underframe 1 one sides;
The frame structure that the handrail link 9 that described upper underframe 2 is a pair of main stay pipe 7 and both sides thereof forms, main stay pipe 7 is connected with central bracket 10, and described handrail link 9 bottoms are connected with respectively a leading truck 8, are provided with the second roller 11 on leading truck 8.
