Abstract
The utility model relates to a sliding screw, wherein the upper end of a screw body is provided with a screw head on which a cross groove is arranged; the bottom end of the screw body is provided with a semi-spherical protrusion which is designed with the screw body into a whole; the diameter of the semi-spherical protrusion is 1/2 that of the screw body; and the periphery of the screw body is provided with external thread. When in use, the sliding screw is screwed into a part through the external thread on the screw body, and slides along the surface of an object through the semi-spherical protrusion at the bottom end, thus not scratching the object. Compared with the prior art, the sliding screw has simple structure, low manufacturing cost, and more convenient and labor-saving use.
Description
Technical field
The utility model relates to a kind of can the slip along body surface, and does not scratch the screw of object, is specifically related to a kind of sliding screw.
Background technique
There are many parts to cooperate with body surface as fulcrum in the life with the screw bottom, slide along body surface, the general employing in the bottom of common flat screw of sliding screw now bored shrinkage pool, and the method for embedded steel ball is made in shrinkage pool then, technology is cumbersome, causes the fabricating cost height; Another kind of sliding screw, be be provided with and follow closely in the bottom of nail body body be designed to one, diameter is also protruding with nail body corresponding to hemisphere, because the arc diameter of nail body front end is consistent with nail body diameter, thereby make the cambered surface and the object area of contact of nail body front end bigger, surface friction drag is big when causing sliding, and stroke is slow.
Summary of the invention
In order to address the above problem, the purpose of this utility model provides a kind of sliding screw, and be provided with and follow closely body to be designed to the hemisphere of one protruding in the bottom of nail body, and the protruding diameter of hemisphere is 1/2 of nail body diameter, and it is simple in structure, and is economical and practical.
The purpose of this utility model is achieved in that a kind of sliding screw, the upper end of nail body is provided with ailhead, ailhead is provided with cross recess, the bottom of nail body is provided with and follows closely body, and to be designed to the hemisphere of one protruding, and the protruding diameter of described hemisphere is 1/2 of the diameter of nail body, and the outer rim of described nail body is provided with outside thread, during use, the utility model is screwed in the part by the outside thread on the nail body, and the hemisphere convex edge body surface slip by the bottom can not scratch object.
The utility model has the advantages that the bottom of nail body is provided with and follows closely body, and to be designed to the hemisphere of one protruding, do not need at nail body bottom hole and nail steel ball again that it is simple in structure, fabricating cost is low; The protruding diameter of hemisphere is 1/2 of the diameter of nail body, has reduced the area of contact with object, has reduced the frictional force with body surface, uses more convenient laborsaving.
Description of drawings
Fig. 1 is a plan view of the present utility model;
Fig. 2 is a plan view of the present utility model.
Among the figure: 1, ailhead; 2, cross recess; 3, nail body; 4, hemisphere is protruding.
Embodiment
The utility model is described in further detail below in conjunction with accompanying drawing:
As shown in Figure 1, a kind of sliding screw, the upper end of nail body 3 is provided with ailhead 1, the bottom of nail body 3 is provided with and follows closely the hemisphere protruding 4 that body 3 is designed to one, the diameter of described hemisphere protruding 4 for the nail body 3 diameter 1/2, the outer rim of described nail body 3 is provided with outside thread, as shown in Figure 2, ailhead 1 is provided with cross recess 2, during use, the utility model is screwed in the part by the outside thread on the nail body 3, regulates the position that the nail body matches with part with screw-driver by the cross recess 2 of ailhead 1, to regulate the suitable gap of part and object, get final product by the slip of hemisphere convex edge body surface, can not scratch object,, operate more laborsaving because hemisphere protruding 4 is little with the body surface area of contact.
Claims (1)
1. sliding screw, the upper end of nail body is provided with ailhead, and ailhead is provided with cross recess, and the outer rim of nail body is provided with outside thread, and the bottom of nail body is provided with and follows closely body, and to be designed to the hemisphere of one protruding, it is characterized in that: the protruding diameter of hemisphere is 1/2 of the diameter of nail body.
