Abstract
The utility model discloses a combined use structure with elastic cylindrical pins. The combined use structure comprises a first workpiece, a second workpiece, an outer elastic cylindrical pin and an inner elastic cylindrical pin, wherein pin holes are opened in the first workpiece and the second workpiece respectively; the outer elastic cylindrical pin is connected with the first workpiece and the second workpiece through the pin holes respectively; the outer diameter of the inner elastic cylindrical pin is less than the outer diameter of the outer elastic cylindrical pin; the inner elastic cylindrical pin is sleeved in the outer elastic cylindrical pin. The combined use structure disclosed by the utility model is simple in structure, capable of enhancing the strengths of the elastic cylindrical pins while improving the non-deformability of the elastic cylindrical pins, and effectively preventing the failure modes such as falling-off of the elastic cylindrical pins.
Description
Technical field
The link that the utility model relates to a kind of axially reciprocating or rotate to use, in particular a kind of elastic cylindrical pin is used in combination structure.
Background technique
At present, the use of elastic cylindrical pin is generally used aloned, the effect that mainly utilizes the opening of elastic cylindrical pin and the elasticity of material to play location, be connected.Elastic cylindrical pin is pressed into after pin-and-hole, and openings get smaller, cylindrical diminish, under elastic reaction with pin-and-hole drive fit.In actual use, because workpiece is frequently stressed, can cause elastic cylindrical pin elastic fatigue to lose efficacy or the inefficacy that gets loose, make to connect or locate failure.
Model utility content
The purpose of this utility model is to overcome the deficiencies in the prior art, and a kind of structure that is used in combination of elastic cylindrical pin is provided, and prevents from coming off and strengthening intensity.
The utility model is achieved through the following technical solutions, and the utility model comprises the first workpiece, second workpiece, outer elastic cylindrical pin and interior elastic cylindrical pin; On described the first workpiece and second workpiece, offer respectively pin-and-hole, outer elastic cylindrical pin connects respectively the first workpiece and second workpiece by pin-and-hole, and the external diameter of interior elastic cylindrical pin is less than the external diameter of outer elastic cylindrical pin, and interior elastic cylindrical pin is set in outer elastic cylindrical pin.
The opening of described outer elastic cylindrical pin and the opening angle of interior elastic cylindrical pin are 180 °, can producing balanced forces.
The utility model has the following advantages compared to existing technology: the utility model is simple in structure, when improving the non-deformability of elastic cylindrical pin, improves the intensity of elastic cylindrical pin, the failure mode such as effectively prevent that elastic cylindrical pin from coming off.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model;
Fig. 2 is the plan view of Fig. 1.
Embodiment
Below embodiment of the present utility model is elaborated; the present embodiment is implemented take technical solutions of the utility model under prerequisite; provided detailed mode of execution and concrete operating process, but protection domain of the present utility model is not limited to following embodiment.
As depicted in figs. 1 and 2, the present embodiment comprises the first workpiece 1, second workpiece 2, outer elastic cylindrical pin 3 and interior elastic cylindrical pin 4; On described the first workpiece 1 and second workpiece 2, offer respectively pin-and-hole, outer elastic cylindrical pin 3 connects respectively the first workpiece 1 and second workpiece 2 by pin-and-hole, the external diameter of interior elastic cylindrical pin 4 is less than the external diameter of outer elastic cylindrical pin 3, and interior elastic cylindrical pin 4 is set in outer elastic cylindrical pin 3.
The opening angle of the opening of described outer elastic cylindrical pin 3 and interior elastic cylindrical pin 4 is 180 °, can producing balanced forces.3 main connections of outer like this elastic cylindrical pin, positioning action, interior elastic cylindrical pin 4 plays supplemental support, improves non-deformability and proposes high-intensity effect.
