Description
Technical field
The utility model relates to spring technical field, is related specifically to a kind of high-strength spring larger for pulling force.
Background technique
Along with the progress of society and the development of machine building industry, and at a kind of resetting means that mechanical machine tool inside often runs into, its inside is provided with spring, and the spring of prior art, the overwhelming majority comprises spring body and is arranged on the connecting body at spring body two ends, and the connecting body being arranged on spring body two ends is usually due to the strength problem of self, under larger pulling force, deform or rupture, and then bringing larger inconvenience to machinery production, the simultaneously also serious working life that have impact on spring.
But for the deficiencies in the prior art, developer be necessary to develop a kind of reasonable in design, structure is simple, tension is effective, not easily deformation and fracture, long service life, self-strength is high, stability is good tension spring.
Summary of the invention
For solving prior art Problems existing, the utility model object provide a kind of reasonable in design, structure is simple, tension is effective, not easily deformation and fracture, long service life, self-strength is high, stability is good tension spring.
For solving above technical problem, the utility model comes to be realize by the following technical solutions: a kind of tension spring, comprises
One spring body, described spring body entirety is cylindrical, and described spring body everywhere pitch is all identical;
Also comprise the upper connecting body being arranged on described spring body one end and the lower connecting body being arranged on the spring body the other end;
Described upper connecting body has into by mutual spiral metal bar spiral together with lower connecting body, and entirety is cylindrical;
Described upper connecting body and the lower connecting body spiral number of turns are more than 2 circles.
In a preferred embodiment of the present utility model, described upper connecting body, spring body and lower connecting body are by metal bar single forming.
In a preferred embodiment of the present utility model, described upper connecting body is excessively connected by the first circular arc with spring body.
In a preferred embodiment of the present utility model, described lower connecting body is excessively connected by the second circular arc with spring body.
In a preferred embodiment of the present utility model, described upper connecting body is identical with lower connecting body pitch, and is less than spring body pitch.
The beneficial effects of the utility model are; Compared with prior art, the utility model comprises spring body, and spring body entirety is cylindrical, and spring body pitch is all identical everywhere; The utility model also comprises the upper connecting body being arranged on spring body one end and the lower connecting body being arranged on the spring body the other end; Upper connecting body has into by mutual spiral metal bar spiral together with lower connecting body, and entirety is cylindrical, upper connecting body and the lower connecting body spiral number of turns are more than 2 circles, and then avoid because pulling force is larger, make the situation that the connecting body at spring body two ends deforms or ruptures, thus improve working life and the tensile strength of spring.
Accompanying drawing explanation
In order to be illustrated more clearly in the utility model embodiment 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 embodiments more of the present utility model, 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.
Fig. 1 is plan view of the present utility model;
Fig. 2 is right elevation of the present utility model;
Fig. 3 is structural representation of the present utility model;
Numeral and the corresponding part title represented by letter in figure:
1. go up connecting body 2. first circular arc 3. spring body 4. second circular arc 5. times connecting body 6. metal bars.
Embodiment
The technological means realized to make the utility model, creation characteristic, reaching object and effect is easy to understand, below in conjunction with concrete diagram, setting forth the utility model further.
Shown in Fig. 1-Fig. 3, the utility model is a kind of tension spring, comprises
One spring body 3, spring body 3 is overall cylindrical, and spring body 3 everywhere pitch is all identical, so the tension uniform making to act on spring be distributed in spring body everywhere, and then avoid pulling force and comparatively concentrate the destruction of causing to spring body 3, thus improve the working life of spring.
The upper connecting body 1 being arranged on spring body 3 one end and the lower connecting body 5 being arranged on spring body 3 the other end is also comprised in the present embodiment, upper connecting body 1 is identical with lower connecting body 5 pitch, and be less than spring body 3 pitch, and then make connecting body 1 and lower connecting body 5 uniform force, thus spring is not easily deformed under larger pulling force.
In the present embodiment, upper connecting body 1 has into by mutual spiral metal bar 6 spiral together with lower connecting body 5, and entirety is cylindrical, and upper connecting body 1, spring body 3 and lower connecting body 5 are by metal bar 6 single forming, and then improve mechanical strength and the stability of spring entirety, thus further increase the working life of spring.
In the present embodiment, upper connecting body 1 and the lower connecting body 5 spiral number of turns are more than 2 circles, thus make connecting body 1 and lower connecting body 5 under larger pulling force, not easily deform and rupture, thus improve tensile strength and the working life of spring.
In the present embodiment, upper connecting body 1 is excessively connected by the first circular arc 2 with spring body 3, lower connecting body 5 is excessively connected by the second circular arc 4 with spring body 3, joint is avoided to be that right angle connects, the stress caused concentrates the damage brought to spring, thus make tension uniform be distributed in spring everywhere, thus improve the tensile strength of spring.
The utility model comprises spring body in sum, and spring body entirety is cylindrical, and spring body pitch is all identical everywhere; The utility model also comprises the upper connecting body being arranged on spring body one end and the lower connecting body being arranged on the spring body the other end; Upper connecting body has into by mutual spiral metal bar spiral together with lower connecting body, and entirety is cylindrical, upper connecting body and the lower connecting body spiral number of turns are more than 2 circles, and then avoid because pulling force is larger, make the situation that the connecting body at spring body two ends deforms or ruptures, thus improve working life and the tensile strength of spring.
More than show and describe basic principle of the present utility model, major character and advantage of the present utility model.The technician of the industry should understand; the utility model is not restricted to the described embodiments; what describe in above-described embodiment and specification just illustrates principle of the present utility model; under the prerequisite not departing from the utility model spirit and scope, the utility model also has various changes and modifications, and these changes and improvements all fall within the scope of claimed the utility model.The claimed scope of the utility model is defined by appending claims and equivalent thereof.
