Abstract
The utility model discloses a plate spring supporting device which imitates the seismograph invented by Zhangheng in East Han Dynasty and comprises a plurality of plate spring supporting members uniformly distributed on a base disk, wherein, each of the plate spring supporting members comprises a fixed seat fixedly connected with the base disk. One end of a plate spring is fixedly connected with the fixed seat, and the other end of the plate spring is provided with a contact head which is contacted with a central column mechanism. The upper part of each of the fixed seat extends to the plate spring to form a cantilever, and a regulating bolt is arranged between the cantilever and the plate spring. The utility model has the advantages that the pre-pressure between the plate springs and the central column is regulated to ensure that when the central column is vertical, the pre-pressure between each contact head of eight plate spring support members and the central column is kept balanced, so that the measurement is accurate.
Description
The utility model relates to a kind of seismograph that shows earthquake generation region that is used to supervise, and relates to the leaf spring bracing or strutting arrangement that the weighing apparatus seismograph is opened by a kind of imitative Eastern Han Dynasty specifically.
Open in the leaf spring supporting construction of weighing apparatus seismograph in the imitative Eastern Han Dynasty in the past, mostly adopt the tooth machine righting mechanism or the wire drawing spring of position, the friction type four directions to set upright middle surely mechanism, but all exist sensitivity relatively poor, the defective that directionality is good inadequately, sensitive bottom valve is unadjustable simultaneously.
The purpose of this utility model just is to provide a kind of sensitivity higher and scalable, and the leaf spring bracing or strutting arrangement of weighing apparatus seismograph is opened by the better imitative Eastern Han Dynasty of directionality.
The purpose of this utility model can realize by following measure:
The utility model comprises the uniform a plurality of leaf spring support members that are arranged on the chassis, the leaf spring support member comprises the holder that is fixed on the chassis, one end of leaf spring is fixed on the holder, the other end of leaf spring is provided with the contact that contacts with post mechanisms all, the top of holder is stretched out direction to leaf spring and is extended with a cantilever, is provided with the adjusting bolt between cantilever and leaf spring.
Holder in the utility model can be made up of two parts up and down, leaf spring one end is inserted into holder by up and down between two parts, holder is fixed on the chassis by bolt, contact is fixed in leaf spring one end by nut, holder also can be designed to integral type, leaf spring can weld or other suitably mode be cemented on the holder.The leaf spring support member is eight, also can set number as required certainly.
Because the utility model adopts uniform leaf spring support member from all directions, each leaf spring support member adopts leaf spring and is used to regulate leaf spring and adjusting bolts of intercolumniation precompression all, make all post when the upright position in eight leaf spring support members each contact keep in balance with precompressions between the post all, make that measurement is more accurate.
Accompanying drawing drawing of the present utility model is described as follows:
Fig. 1 is the utility model front view.
Fig. 2 is that the utility model is placed in the overall diagram in the seismograph.
The utility model is done explanation in further detail below in conjunction with drawings and Examples:
As shown in the figure: principle of work of the present utility model is as follows: it comprises uniform eight leaf spring support members that are arranged on the chassis 10, the leaf spring support member comprises the holder 9 that is fixed on the chassis 10, one end of leaf spring 1 is fixed on the holder 9, the other end of leaf spring 1 is mounted with the contact 2 that contacts with post mechanisms 11 all, contact 2 is fixed in leaf spring 1 one ends by nut 4, between nut 4 and leaf spring 1 pad 3 is installed.The top of holder 9 is extended with cantilever to leaf spring 1 direction, is mounted with to regulate bolt 5 between cantilever and leaf spring 1, between adjusting bolt 5 and holder 9 set nut 6 is installed.Holder 9 is made up of two parts 7,9 up and down, and leaf spring 1 one ends are inserted into up and down between two parts of holder 9, and holder 9 is fixed on the chassis 10 by bolt 8.
Principle of work of the present utility model is as follows: regulate to regulate bolt make all post when the upright position in eight leaf spring support members each contact and all the precompression between the post keep in balance, thereby measure seismologic parameter more accurately.
