Abstract
The utility model relates to a protecting cap nut, which is characterized in that the protecting cap is provided with a cavity structure. The inner wall of the cavity is provided with threads, the bottom of the cavity is a concave, a slot deeper than the outside diameter of the thread are arranged on the inner wall in the cavity along the threaded shaft direction, and the slot is communicated with the threads and the bottom of the cavity. Oil can be added on the cavity bottom of the protecting cap when using, and the protecting cap can be tightly screwed on an exposed screw shaft which is pre-fixed with a nut. The utility model can effectively protect the screw bolts and the nuts, so the dismounting is convenient.
Description
The utility model is a kind of Cap nut.
Existing screw is owing to expose outside for a long time, and very easily corrosion is to making screw dismounting difficulty.
The purpose of this utility model is to provide a kind of can prevent the screw corrosion, easy-to-dismount Cap nut.
Fig. 1, Fig. 2 are the design's structural representation.
Fig. 3 is the use figure of Cap nut.
Cap nut is cavity body structure, and cavity inner wall is shaped with screw thread 1, and cavity bottom is spill, along screw thread 1 axially, have a groove 2 darker than screw thread 1 external diameter at cavity inner wall, groove 2 is communicated with screw thread 1 and cavity bottom. Cavity bottom is placed the material of grease one class; Cap nut is screwed on the lead screw 4 of nut 3 afterbodys; rotation propelling along with Cap nut; grease is squeezed and enters in whole screw threads 1 along groove 2; and be coated on the thread surface of lead screw 4; until fit in helmet and nut 3 planes, completely cut off lead screw 4 and extraneous contacting, played the effect of protection screw.
In addition, the helmet top is spherical, has increased intensity, to strengthen the intensity that it is subjected to external force to collide with and pushed by the inner chamber grease.
And helmet is made hexagon, so that use.Cap nut also can adopt plastic productions such as PVC.
The utility model can be protected bolt, nut effectively, makes its convenient disassembly, during use; as long as grease be added in the helmet cavity bottom and be tightened on the lead screw 4 that fastening good nut 3 exposes; if it is longer to expose lead screw 4, but cushioning sheath 5, as shown in Figure 3.
