Abstract
The invention relates to a lithologic density probe fastening screw. At present, the lower end of a universal lithologic density probe fastening screw is flatheaded, and in a mounting process, due to the unreasonable design, the conditions that the mounting is difficult and other fitting pieces are easy to damage are caused, which is not beneficial to product assembly and maintenance. The lithologic density probe fastening screw comprises a screw head and a threaded rod, wherein the lower end of the threaded rod is tapered. In the invention, the design of the universal lithologic density probe fastening screw is changed, and the lithologic density probe fastening screw disclosed by the invention is easy to install and is beneficial to the reduction of the probability of damaging the other fitting pieces, the improvement of working efficiency and the reduction of the production and maintenance cost of an instrument.
Description
Technical field
The present invention relates to a kind of lithology and density logging probe holding screw.
Background technology
At present, the screw rod of general lithology and density logging probe holding screw, structure design is unreasonable, causes difficulty is installed, and the situation of fragile other counterparts is unfavorable for product assembling and maintenance.
Summary of the invention
The present invention is in order to overcome the installation difficulty of lithology and density logging probe holding screw, and fragile other accessory keeps in repair and the problem of assembling difficulty provides a kind of novel lithology and density logging probe holding screw.
Technical scheme of the present invention is: a kind of lithology and density logging probe holding screw, to form by screw terminal and screw rod, and the lower end of described screw rod is taper.
The invention has the beneficial effects as follows: easily install, reduce the probability of damaging other counterparts, improve the efficient of work, lowered the production and the maintenance cost of instrument.
