Abstract
The invention discloses a spring with pressure feet. The spring comprises a spring body which is mutually matched with an existing hinge folded sheet, wherein the spring body comprises a spring main body; the spring main body is integrally cylindrical; the spring also comprises an upper pressure foot arranged at the upper end of the spring main body and a lower pressure foot arranged at the lower end of the spring main body; the upper pressure foot and the lower pressure foot are formed by mutually twisting metal strips, and the bending angle is 180 degrees. The spring disclosed by the invention has the advantages of reasonable design, simple structure, small pressure intensity of the pressure feet and the hinge folded sheet, high mechanical strength, long service life and high stability.
Description
Technical field
The present invention relates to spring technical field, be related specifically to a kind of spring with presser feet.
Background technique
In order to make to relatively rotate between face and face, also home position can be automatically restored to simultaneously, and then need between two faces, be provided with a spring, then completed by this spring and relatively rotate, finally return to original position, such as hinge, automatically close in order to door can be made, and then in hinge mounting spring, thus complete this process.
And in prior art, be arranged on the spring of hinge inside, be provided with the presser feet at the upper and lower two ends of spring body, be pressed on two hinge folded pieces respectively, due to presser feet and hinge folded piece area of contact less, and then when spring receives larger warping force, make to produce larger pressure between presser feet and hinge folded piece, thus hinge folded piece is damaged, also certain destruction is caused to spring body simultaneously, thus have impact on the working life of spring.
But for the deficiencies in the prior art, developer is necessary to develop that a kind of reasonable in design, structure is simple, presser feet and hinge folded piece pressure is less, mechanical strength is high, long service life, homeostasis performance the are strong spring with presser feet.
Summary of the invention
For solving prior art Problems existing, the object of the invention provide a kind of reasonable in design, structure simple, presser feet and hinge folded piece pressure is less, mechanical strength is high, long service life, homeostasis performance the are strong spring with presser feet.
For solving above technical problem, the present invention comes to be realize by the following technical solutions: a kind of spring with presser feet, comprises the spring body cooperatively interacted with existing hinge folded piece;
Described spring body comprises spring body, and described spring body entirety is cylindrical;
Also comprise the upper presser feet be provided with in spring body upper end and the lower presser feet being arranged on spring body lower end;
Described upper presser feet is with lower presser feet by mutual metal bar is distorted into mutually, and bend angle is 180 °.
In a preferred embodiment of the invention, described spring body, upper presser feet and the once-through of lower presser feet metal bar.
In a preferred embodiment of the invention, described upper presser feet and spring body and to be all excessively connected with circular arc between presser feet and spring body down.
In a preferred embodiment of the invention, described upper presser feet and lower presser feet angle scope 45-60 °.
In a preferred embodiment of the invention, pitch is all identical everywhere for described Returnning spring body.
Beneficial effect of the present invention is; Compared with prior art, the present invention is provided with the spring body that existing hinge folded piece cooperatively interacts; Described spring body comprises spring body, and described spring body entirety is cylindrical; Also comprise the upper presser feet be provided with in spring body upper end and the lower presser feet being arranged on spring body lower end; Described upper presser feet with lower presser feet by mutual metal bar is distorted into mutually, and bend angle is 180 °, and then avoid presser feet and hinge folded piece area of contact is less, to the destruction that hinge brings, it also avoid the damage brought to spring self simultaneously, thus improve working life and the stability of spring.
Accompanying drawing explanation
In order to be illustrated more clearly in the embodiment of the present invention or technological scheme of the prior art, be briefly described to the accompanying drawing used required in embodiment or description of the prior art below, apparently, accompanying drawing in the following describes is only some embodiments of the present invention, for those of ordinary skill in the art, under the prerequisite not paying creative work, other accompanying drawing can also be obtained according to these accompanying drawings.

Embodiment
The technological means realized to make the present invention, creation characteristic, reaching object and effect is easy to understand, below in conjunction with concrete diagram, setting forth the present invention further.
Shown in Fig. 1-Fig. 3, the present invention is a kind of spring with presser feet, comprises the spring body cooperatively interacted with existing hinge folded piece;
The present embodiment medi-spring body comprises spring body 2, and spring body 2 is overall cylindrical, and spring body 2 pitch is all identical everywhere, thus improve spring body 2 self by force intensity, further increase the working life of spring.
The upper presser feet 1 be provided with in spring body 2 upper end and the lower presser feet 3 being arranged on spring body 2 lower end is also comprised in the present embodiment, and upper presser feet 1 is all excessively connected with circular arc 5 with spring body 2 with between lower presser feet 3 and spring body 2, and then avoid spring stress inequality, to the damage that spring brings, thus improve the stability of spring self.
Presser feet 1 is gone up with lower presser feet 3 by mutual metal bar 4 is distorted into mutually in the present embodiment, and bend angle is 180 °, also can be other angle, this angle is mainly used in the contact expanding presser feet and hinge folded piece, thus the pressure between reducing, further increase the working life of spring.
Metal bar 4 once-through of the present embodiment medi-spring body 2, upper presser feet 1 and lower presser feet 3, thus improve the mechanical strength of spring entirety, further increase the working life of spring.
Upper presser feet 1 and lower presser feet 3 angle scope 45-60 ° in the present embodiment, and go up presser feet 1 in the present embodiment and the preferred angle of lower presser feet 3 is 45 °.
The present invention is provided with the spring body that existing hinge folded piece cooperatively interacts in sum; Described spring body comprises spring body, and described spring body entirety is cylindrical; Also comprise the upper presser feet be provided with in spring body upper end and the lower presser feet being arranged on spring body lower end; Described upper presser feet with lower presser feet by mutual metal bar is distorted into mutually, and bend angle is 180 °, and then avoid presser feet and hinge folded piece area of contact is less, to the destruction that hinge brings, it also avoid the damage brought to spring self simultaneously, thus improve working life and the stability of spring.
More than show and describe basic principle of the present invention, major character and advantage of the present invention.The technician of the industry should understand; the present invention is not restricted to the described embodiments; what describe in above-described embodiment and specification just illustrates principle of the present invention; the present invention also has various changes and modifications without departing from the spirit and scope of the present invention, and these changes and improvements all fall in the claimed scope of the invention.Application claims protection domain is defined by appending claims and equivalent thereof.
