Abstract
The utility model discloses a cylindrical pin which is characterized by comprising a pin body portion (1) installed in a pin hole, and a pin tail portion (2). The section of the pin body portion (1) is round, the pin tail portion (2) is arranged on the end portion of the pin body portion, the pin tail portion is provided with an arc-shaped side wall (20) and a cutting face (21), and the circumference diameter of the pin tail portion gradually changes in the free end direction of the pin tail portion. The cylindrical pin has the advantages that the structure of a plurality of sections in different sizes of the cylindrical pin can play a good role of guiding, installation and placement of a workpiece is rapider and more stable, and the accuracy rate of assembly is improved.
Description
Technical field
The utility model relates to a kind of straight pin.
Background technique
It is comparatively extensive that straight pin uses, be equipped with usually match and pin-and-hole, for the straight pin afterbody outside being exposed to pin-and-hole, do not possess guide function usually, can't realize fast installing the needs of workpiece.
The model utility content
The purpose of this utility model is exactly in order to address the above problem, and a kind of straight pin is provided.
To achieve these goals, the utility model adopts following technological scheme:
A kind of straight pin is characterized in that, has:
Be installed on the shank part (1) of pin-and-hole, its cross section is rounded;
Be located at the pin portion (2) of shank part end, the pin portion has a curved wall (20) and a cutting face (21), and described pin portion is the gradual change shape towards its free end direction Zhou Jing.
Further, described pin portion diminishes gradually towards its free end direction Zhou Jing.
Further, described pin portion is provided with equal-diameter part and non-equal-diameter part and the length of the two than being 1:1.
Further, described non-equal-diameter part contains the pilot unit that two sections Zhou Jing gradually change at least.
Further, described cutting face contains:
First plane (21a) that extend towards the top bottom of self-marketing portion;
Second plane (21b) adjacent with first plane;
Three plane (21c) adjacent with second plane.
The beneficial effects of the utility model are:
(1) the different size shape structures of the multistage of straight pin can play good leading role, can make workpiece quick more, stable when installation is put, and improve the accuracy rate of assembling.
(2) the cutting face design helps the assembling of straight pin, and the cutting face presents the multistage design.

Embodiment
For technological means, creation characteristic that the utility model is realized, reach purpose and effect is easy to understand, below in conjunction with concrete diagram, further set forth the utility model.
Shown in Fig. 1～5, a kind of straight pin, it has: be installed on the shank part 1 of pin-and-hole, its cross section is rounded; Be located at the pin portion 2 of shank part end, the pin portion has a curved wall 20 and a cutting face 21, and described pin portion is the gradual change shape towards its free end direction Zhou Jing.
Described pin portion diminishes gradually towards its free end direction Zhou Jing.
Described pin portion is provided with equal-diameter part and non-equal-diameter part and the length of the two than being 1:1.
Described non-equal-diameter part contains the pilot unit that two sections Zhou Jing gradually change at least, particularly, referring to Fig. 4, non-equal-diameter part have the first guide section M that is positioned at pin portion top and with the second guide section N.
Referring to Fig. 5, described cutting face contains: the first plane 21a that extend towards the top bottom of self-marketing portion; The second plane 21b adjacent with first plane; The three plane 21c adjacent with second plane.
The above only is preferred implementation of the present utility model, and protection domain of the present utility model is not limited in above-mentioned mode of execution, and every technological scheme that belongs to the utility model principle all belongs to protection domain of the present utility model.For a person skilled in the art, some improvement of under the prerequisite that does not break away from principle of the present utility model, carrying out, these improvement also should be considered as protection domain of the present utility model.
