Abstract
The utility model is related to mapping equipment technical field more particularly to a kind of novel prism centering rods.The novel prism centering rod includes the body of rod and prism, and the prism is fixed on body of rod top by prism bracket, and body of rod lower end is equipped with sleeve, is fixed with symmetrically arranged connecting rod on sleeve, the integration of connecting rod end is connected with support plate；The body of rod bottom end is threaded with head protective device, and head protective device is to be internally provided with the cylindrical structure of through-hole, and internal thread is equipped in through-hole.The novel prism centering rod reasonable design, head protective device can play a protective role to head, reduce the abrasion of head, improve measurement accuracy；The setting of support plate can enhance the stability of centering rod, convenient for correction, improve the accuracy of measurement data.
Description
（One）Technical field
The utility model is related to mapping equipment technical field more particularly to a kind of novel prism centering rods.
（Two）Background technology
Centering rod is the matching used instruments of instruments such as a kind of and total powerstation, theodolite, is generally used for positioning, to work(
Energy.The vertical of centering rod all manually operates at present, and due to artificial origin when engineering survey or setting-out, centering rod is difficult to reach
To high-precision vertical or during vertical needing to take a significant amount of time, and centering club head tip is easy to wear, can lead
Cause the decline of measurement accuracy.
（Three）Utility model content
The utility model in order to make up for the deficiencies of the prior art, provides a kind of novel prism centering rod.
The utility model is achieved by the following technical solution：A kind of novel prism centering rod, including the body of rod and prism,
It is characterized in that：The prism is fixed on body of rod top by prism bracket, and body of rod lower end is equipped with sleeve, is fixed on sleeve pair
The connecting rod of setting, the integration of connecting rod end is claimed to be connected with support plate；The body of rod bottom end is threaded with head protection dress
It sets, head protective device is to be internally provided with the cylindrical structure of through-hole, and internal thread is equipped in through-hole.
Further, the sleeve is sleeved on the body of rod and is tightened by bolt.
Further, it is installed with air-bubble level on the body of rod.
The utility model has the beneficial effects that：The novel prism centering rod reasonable design, head protective device can be to bar
Head plays a protective role, and reduces the abrasion of head, improves measurement accuracy；The setting of support plate can enhance the stabilization of centering rod
Property, convenient for correction, improve the accuracy of measurement data.
（Four）Description of the drawings
The utility model will be further described below with reference to the accompanying drawings.
Attached drawing 1 is the structural schematic diagram of the utility model.
In figure, 1, the body of rod, 2, prism, 3, prism bracket, 4, sleeve, 5, connecting rod, 6, support plate, 7, head protection dress
It sets, 8, head, 9, bolt, 10, air-bubble level.
（Five）Specific implementation mode
The utility model is described in further detail with reference to specific embodiment.
As shown in Fig. 1, which includes the body of rod 1 and prism 2, and the prism 2 is fixed on the body of rod by prism bracket 3
1 top, 1 lower end of the body of rod are equipped with sleeve 4, and symmetrically arranged connecting rod 5,5 end integration connection of connecting rod are fixed on sleeve 4
There is support plate 6；1 bottom end of the body of rod is threaded with head protective device 7, and head protective device 7 is to be internally provided with through-hole
Cylindrical structure, through-hole is interior to be equipped with internal thread.
The sleeve 4 is sleeved on the body of rod 1 and is tightened by bolt 9.
Air-bubble level 10 is installed on the body of rod 1.
In use, head protective device 7 is turned upwards, head 8 is made to expose, then adjusts height of the sleeve 4 on the body of rod 1
Degree, and rotational sleeve 4, make two support plates 6 be contacted with ground, tighten bolt 9 later, can enhance the stabilization of centering rod in this way
Property, convenient for correction, improve the accuracy of measurement data；Head protective device 7 is turned downwards after use, it is made to wrap bar
First 8, to reduce the abrasion of head 8, improve measurement accuracy.
Embodiment described above, only one kind of the utility model more preferably specific implementation mode, the skill of this field
The usual variations and alternatives that art personnel carry out within the scope of technical solutions of the utility model should all be included in the guarantor of the utility model
It protects in range.
