其实礼堂椅最重要的部位不是在外观，就像人一样，不是看他外表，椅子的质量我们主要是看他的心脏--底盘，在礼堂椅的坐垫下面有个重要的部分就是底盘，底盘的质量是我们在生产过程发现的最最重要的部件，他能有几种损坏的结果，椅子吱吱响基本就是底盘的问题，椅子的左右摇晃也是底盘问题，椅子升降不起来很多也是底盘问题，靠背的松垮基本也是底盘的链接部位发生问题。

In fact, the most important part of the auditorium chair is not in appearance, like people, not see his appearance, the quality of the chairs we basically is to see his heart - chassis, chair cushion in the hall there is an important part of the following is the chassis, chassis quality is that we found in the production process of the most important components, he can have several damaged as a result, the chair is squeaking basic chassis, chair swung and chassis, chair lift up a lot of is also chassis problem, back of a chair of loose basic problems is also links to parts of the chassis.

如何判读一只好的底盘，首先是底盘的铁的厚度，一般好的底盘厚度是在2mm以上的钢板的厚度，才能有效的支撑整张椅子和人的重量。

How to reading a good chassis, the thickness of the first is the iron of the chassis, general good chassis in more than 2 mm is the thickness of the steel plate thickness, to effectively support the whole chair and the weight of the people.

第二要看底盘的机构，简单的底盘称为蝴蝶盘，这是最简单很多小椅子用，还有底盘是小飞机座，大飞机座，还有青蛙底盘，当然也有尾板底盘，也有线控底盘，这里的机构都比较复杂，设计椅子时候通常就是在底盘上下功夫，底盘的结构约好，则功能越多，底盘的机构约合理则礼堂椅较结实。

Second to look at the institution of chassis, simple chassis called butterfly plate, this is the simplest many small chair, and chassis is small aircraft, large aircraft, and the frog chassis, of course, there are tail plate chassis, chassis, wire and the agency here are more complex, the design when the chair is usually in the chassis, chassis structure of appointment, the function, the chassis of the institutions about the rational criterion auditorium chair is strong.

底盘的中心在礼堂椅的距离里面起着非常重要的作用，靠前了容易前翻，靠后了容易后翻，当然靠左右时，容易左右摇晃，受力不均匀。所以底盘安装在椅子上后需要试坐，并要摇晃椅子判断这是否好的椅子。

The center of the chassis at the auditorium chair range plays a very important role, from the easy to move forward, back, after the easy, of course, depend, easily swung, stress is not uniform. After the chassis to install on the chair so need to try to sit, and rocking chair judge whether it is good.

底盘和背铁的链接件，普通的椅子都是通过手雷上面的弯铁链接，这个弯管容易变形很多人的课桌椅后来都靠背歪斜，断裂等都是这个原因，所以一定要看底盘和背铁的链接件，好的椅子都是通过非常厚实的加强过的背铁链接，链接的螺丝是三个及以上，所以我们一定要把底盘的前后都看过。

Chassis and back iron links, ordinary bending chains by grenades on the chair, the bend easy deformation of many desks and chairs are later back askew, fracture is for this reason, so be sure to see the links, chassis and back iron good chair is very thick with strengthening the back chains, link the screws are three or more, so we must have seen before and after the chassis.

更好的椅子的扶手都是和底盘来链接的，因为只有这样才是最稳当的，国外新款设计的人性工学椅通常都是在底盘上链接扶手，如果扶手打在座椅的底板上，其实还是不是很理想，目前绝大部分都是这样的链接方式，相信后面产品应该可以得到更大的改进。

Better chair armrest and chassis to link, because only in this way is the most secure, chair of the new design of human engineering abroad are usually link handrails on the chassis, if the handrail in the seat of the floor, it is not very ideal, at present most of the links, believe that the product should be able to get a bigger improvement.

底盘是礼堂椅的心脏

The chassis is the heart of the auditorium chairs
