Abstract
The utility model relates to a protective device for a CPIII surveying mark embedded part. A high-speed railway foundation pile control net (CPIII) has the characteristics of multiple observing points, onerous surveying task, high precision, and the requirement of high automation on the operation process and the like; and the surveying mark embedded part needs to be repeatedly used for a long time, and due to the lack of protection, outside air and rainwater and the like often enter the surveying embedded part. The utility model provides the protective device for the CPIII surveying mark embedded part, which comprises a protective cap, and one end of the protective cap is in threaded connection with a screwing screw. By the adoption of the structure, when surveying dose not need to be conducted, and after the screwing screw is screwed into the protective cap, the protective cap is inserted into the surveying mark embedded part, and then the screwing screw is screwed out and take away, thus preventing foreign bodies from entering the mark embedded part, and realizing effective protection.
Description
Technical field:
The utility model belongs to the high-speed railway field of measuring technique, relates to a kind of CPIII survey mark built-in fitting protective device.
Background technology:
High-speed railway foundation pile control net (CPIII) has that observation point is many, the measurement task is heavy, high accuracy and the characteristics such as high automation that require operation process; yet the survey mark built-in fitting needs long-term the repeated use; in order to prevent that outside air and rainwater etc. from entering the measurement built-in fitting; traditional guard member just adopts the steel screw to stop up; yet the steel screw can not secluding air and rainwater; be easy to generate corrosion, and should not take out built-in fitting after the corrosion, be unfavorable for the long preservation of built-in fitting.
The utility model content:
The technical problems to be solved in the utility model provides a kind of CPIII survey mark built-in fitting protective device, solves to be difficult for taking out after the conventional steel screw is easy to generate corrosion and corrosion, is unfavorable for the problem of built-in fitting long preservation.
For solving the problems of the technologies described above, the technical solution adopted in the utility model is: a kind of CPIII survey mark built-in fitting protective device, comprise protective cap, and the threaded one end connection of protective cap screws screw.
Above-mentioned protective cap is made up of cap head, cock body and sealing ring, and the first end of cap connects cock body, sheathed sealing ring on the cock body.
Above-mentioned protective cap is structure as a whole.
Above-mentioned protective cap adopts plastic material to make.
This kind structure that the utility model adopts; when in the time need not measuring; after will screwing screw screw-in cap head; protective cap is inserted the survey mark built-in fitting; screw out again and take away and screw screw and get final product, can prevent that foreign matter from entering the sign built-in fitting, realize effectively protection; and protective cap is made by plastic material, can not get rusty.
Description of drawings:
Fig. 1 is the utility model structural representation.
Among the figure, the 1-cock body, the 2-sealing ring, 3-cap head, 4-screws screw.
The specific embodiment:
Below by accompanying drawing the utility model is specifically described:
Referring to Fig. 1; a kind of CPIII survey mark built-in fitting protective device; comprise a protective cap; protective cap is by cap head 3; cock body 1 and sealing ring 2 are formed; the three is structure as a whole; cap head 3 one ends connect cock body 1; the sheathed sealing ring 2 in cock body 1 top and the bottom; the other end internal thread of cap head 3 is connected with and screws screw 4; screwing screw 4 can screw in freely; screw out cap head 3; and in cap head 3, break away from, cap head 3 is the end cap shape and is connected with cock body 1, and diameter is greater than cock body 1 diameter; both adopt the moderate plastic material of hardness to make; both outer main diameters are corresponding with the internal diameter of survey mark built-in fitting, and sealing ring 2 adopts the soft slightly plastic production of hardness, can guarantee effectively to deaden foreign matters such as outside air and rainwater and enter the measurement built-in fitting.
In the time need not measuring, will screw screw and screw in the cap head, protective cap is inserted the survey mark built-in fitting, screw screw again and take away, prevent that foreign matter from entering; When need measuring, will screw in the screw precession protective cap head, and extract protective cap in the built-in fitting then and get final product.
