Hurry up, high precision and the small Novel hung prism of error.
Above-mentioned technical problem of the present utility model is mainly what is be addressed by following technical proposals：
The Novel hung prism that the utility model is provided, including prism and reflective panel, the reflective panel are arranged on institute
State on the excircle of prism, it also includes hitch, fixed support and plumb bob, and the hitch and fixed support set respectively
Put at the upper middle position and lower middle position of the reflective panel, the hitch also through outside connecting line with
Point to be measured is connected, wherein, the support bracket fastened bottom also with the plumb bob detachable connection.
Further, the fixed support includes multiple connection pawl and mounting discs, the setting at multiple connection pawl intervals
On the upper surface circumferencial direction of the mounting disc, and bottom of the connection pawl also with the reflective panel is fixedly connected, institute
The inside for stating mounting disc is additionally provided with a screwed hole, and the upper surface of the plumb bob is provided with a screw rod, the screw rod and the screwed hole
It is engaged.
Further, the hitch includes through hole, and the through hole is located at the upper middle position of the reflective panel
Place, and the through hole a diameter of 1-3mm.
Further, the plumb bob is made using round steel, and the bottom of the plumb bob is additionally provided with a conical surface.
Further, multiple connection pawls are equally spaced on the upper surface circumferencial direction of the mounting disc.
Further, the diameter and length of the screw rod are respectively 15mm and 20mm.
The beneficial effects of the utility model are：Prism is directly hung on by hitch and connecting line for point to be measured
On, then recycle the plumb bob substitution tripod of fixed support bottom to carry out fixed prism, it is achieved thereby that under the complex environment of tunnel
Accessible measurement, it not only reduces human factor and brings measurement error, alleviates the labour intensity of survey crew, Er Qieti
High measuring speed and precision.
Brief description of the drawings
In order to illustrate more clearly of the utility model embodiment or technical scheme of the prior art, below will be to embodiment
Or the accompanying drawing to be used needed for description of the prior art is briefly described, it should be apparent that, drawings in the following description are only
It is some embodiments of the present utility model, for those of ordinary skill in the art, is not paying the premise of creative work
Under, other accompanying drawings can also be obtained according to these accompanying drawings.
Fig. 1 is the structural representation of Novel hung prism of the present utility model；
Fig. 2 is the prism of Novel hung prism of the present utility model and the structural representation of reflective panel；
Fig. 3 is the structural representation of the plumb bob of Novel hung prism of the present utility model.
Specific embodiment
Preferred embodiment of the present utility model is described in detail below in conjunction with the accompanying drawings, so that advantage of the present utility model
Can be easier to be readily appreciated by one skilled in the art with feature, it is apparent clear and definite so as to be made to protection domain of the present utility model
Define.
Refering to shown in Fig. 1-3, Novel hung prism of the present utility model, including prism 1 and reflective panel 2, reflective panel 2
It is arranged on the excircle of prism 1, it also includes hitch 3, fixed support 4 and plumb bob 5, hitch 3 and fixed support 4
Be separately positioned at the upper middle position of reflective panel 2 and lower middle position, hitch 3 also through outside connecting line with
Point to be measured is connected, wherein, the bottom of fixed support 4 also with the detachable connection of plumb bob 5, so facilitate the peace of plumb bob 5
Dress, dismounting and replacing.
The utility model is directly hung on point to be measured prism 1 by hitch 3 and connecting line, is then recycled
The substitution tripod of plumb bob 5 of the bottom of fixed support 4 carrys out fixed prism 1, it is achieved thereby that the accessible survey under the complex environment of tunnel
Amount, it not only reduces human factor and brings measurement error, alleviates the labour intensity of survey crew, and improves measurement speed
Degree and precision.
Specifically, fixed support 4 includes multiple connection pawl 41 and mounting discs 42, and what multiple connection pawl 41 was spaced is arranged on peace
