Abstract
The utility model discloses a U-shaped pin which comprises two clamping parts and a bending part enabling the upper portions of the clamping parts to be connected. The two clamping parts are respectively provided with a free end, the free end of each clamping part is provided with an arc-shaped structure bending towards the direction far away from the other clamping part, the free ends of the two clamping parts form a trumpet-shaped opening, the straight line parts of the two clamping parts are parallel to each other, and arc-shaped chamfering is arranged on the outer side of the U-shaped pin. According to the U-shaped pin, structural improvement is achieved on the U-shaped pin, the U-shaped pin is simple in structure, stress concentration is not prone to generating, and the U-shaped pin is not prone to breaking.
Description
Technical field
The utility model relates to technical field of fastening, relates in particular to a kind of U-shaped pin.
Background technique
U-shaped pin, as a kind of fastening piece, is commonly used to connect or fixing different parts.Because U-shaped pin has easy accessibility, fixed, use the advantages such as simple, be used widely.In prior art, in use, find that U-shaped pin can rupture because stress is concentrated.
Model utility content
In order to solve the technical problem existing in background technique, the utility model proposes a kind of U-shaped pin, realize the architecture advances to U-shaped pin, it is simple in structure, is difficult for producing stress and concentrates and easy-rupturing not.
A kind of U-shaped pin the utility model proposes, comprise two clamping parts and the curved part that is connected described clamping part top, two described clamping parts all have free end, the oriented arcuate structure away from another clamping part direction bending of free ending tool of described clamping part, and the free end that adds the portion of holding described in two forms horn-like opening, the straight section of two described clamping parts is parallel to each other, and the arranged outside of described U-shaped pin has arc angling.
Preferably, described U-shaped pin is symmetrical with the perpendicular bisector of described curved part.
Preferably, the arc of described U-shaped pin outer arcuate chamfering is semicircle.
In the utility model, the opening forming by the free end of two clamping parts connects article to be connected or to be clamped or clamp, and is designed to arcuate structure by adding the free end of holding, and forms horn-like opening, and connection or clamp operation are more prone to; At the arranged outside arc angling of U-shaped pin, can effectively prevent that stress is concentrated, improve the bearing capacity of U-shaped pin, and the working life that can effectively improve U-shaped pin.
Accompanying drawing explanation
Fig. 1 is the structural representation of a kind of U-shaped pin that the utility model proposes;
Fig. 2 is the schematic cross-section of U-shaped pin in Fig. 1.
Embodiment
As shown in Figure 1 and Figure 2, Fig. 1 is the structural representation of a kind of U-shaped pin that the utility model proposes; Fig. 2 is the schematic cross-section of U-shaped pin in Fig. 1.
See figures.1.and.2, a kind of U-shaped pin the utility model proposes, comprise two clamping parts 1 and the curved part 3 that is connected described clamping part 1 top, two described clamping parts 1 all have free end, the oriented arcuate structure 2 away from another clamping part 1 direction bending of free ending tool of described clamping part 1, and the straight section that the free end that adds the portion of holding described in two forms 4, two described clamping parts 1 of horn-like opening is parallel to each other, and the arranged outside of described U-shaped pin has arc angling 5.
In specific design process, described U-shaped pin is symmetrical with the perpendicular bisector of described curved part 3, thereby makes the clamping part 1 of U-shaped pin stressed more even.
In the present embodiment, the arc of described U-shaped pin outer arcuate chamfering 5 is semicircle.
In the utility model, the opening 4 forming by the free end of two clamping parts 1 connects article to be connected or to be clamped or clamp, be designed to arcuate structure 2 by adding the free end of holding, form horn-like opening 4, connection or clamp operation are more prone to; At the arranged outside arc angling 5 of U-shaped pin, can effectively prevent that stress is concentrated, improve the bearing capacity of U-shaped pin, and the working life that can effectively improve U-shaped pin.
The above; it is only preferably embodiment of the utility model; but protection domain of the present utility model is not limited to this; any be familiar with those skilled in the art the utility model disclose technical scope in; be equal to replacement or changed according to the technical solution of the utility model and model utility design thereof, within all should being encompassed in protection domain of the present utility model.
