Abstract
The utility model discloses an arc spring. A spring body (1) of the spring is an arc structure; and the pitch of the spring body (1) becomes larger gradually from the middle of the spring body to the directions of the two ends or the pitch of the spring body (1) becomes smaller gradually from the middle of the spring body to the directions of the two ends. The arc spring can realize the better matching state of the spring with the used accessories, expand the change range of used moment to greater extent and have wider use range and simple and effective structure.
Description
Technical field
The utility model relates to a kind of spring, and especially a kind of spring body structure of spring is similar to the arc spring of banana.
Background technique
Spring is widely used a kind of elastic element in machinery and the electron trade, spring can produce bigger resiliently deformable when stand under load, mechanical work or kinetic energy are converted into energy of deformation, and the distortion of unloading rear spring disappears and reinstatement, and energy of deformation is converted into mechanical work or kinetic energy.Pressure spring is a kind of helical spring that bears pressure in the spring, be a kind of spring that is the most extensively used in all spring kinds, product application range extensively reaches occasions such as electronics, motor, steam turbine car, bicycle, hardware ﹠ tools, gift, toy and even national defense industry, because of its design and principle are easy to grasp, production control is also simple.Between the circle of pressure spring and the circle certain clearance is arranged, spring contraction deformation when being subjected to external load stores energy of deformation.And the distortion of unloading rear spring disappears and reinstatement, and energy of deformation is converted into mechanical work or kinetic energy, and purposes is the widest.During fabrication, the spiral ring that coiled separates, make each circle that pitch be arranged, so that stressed contraction maintains the tension force of upholding to two ends, can not be compressed fully by busy hour, retention gap between number of active coils is when still the space environment structure situation of installing and using when spring is required is more special, particularly when needing use under the situation in circular product or arc structure space, common spring can't satisfy this type of and use needs, more can't satisfy wide moment variations demand.
The model utility content
The utility model can't use in circular product or arc structure space for solving common spring, can't satisfy the present situation of wide moment variations and a kind of arc spring of providing.
The utility model is to solve the problems of the technologies described above the concrete technological scheme that is adopted to be: a kind of arc spring, and the spring body diameter of spring is an arcuate structure, the pitch of spring body becomes big by in the middle of the spring body gradually to direction of both ends.To a greater extent widened employed moment variations scope.
As preferably, the another kind of structure of spring body is that pitch diminishes to direction of both ends gradually by in the middle of the spring body.
The beneficial effects of the utility model are: can realize the better mated condition with the accessory that uses, to a greater extent widened employed moment variations scope.Using scope is wider, and is simple in structure effective.
Description of drawings:
Below in conjunction with the drawings and specific embodiments the utility model is described in further detail.
Fig. 1 is a kind of structural representation of the utility model arc spring.
Fig. 2 is the another kind of structural representation of the utility model arc spring.
Embodiment
Among the embodiment 1 shown in Figure 1, a kind of arc spring, spring body 1 external diameter of spring is an arcuate structure, the pitch of spring body 1 becomes big by in the middle of the spring body gradually to direction of both ends.
Among the embodiment 2 shown in Figure 2, a kind of arc spring, spring body 1 external diameter of spring is an arcuate structure, the pitch of spring body 1 diminishes to direction of both ends gradually by in the middle of the spring body.
Claims (2)
1. arc spring, it is characterized in that: the spring body (1) of described spring is shaped as arcuate structure, and the pitch of spring body (1) becomes big by in the middle of the spring body gradually to direction of both ends.
2. according to the described arc spring of claim 1, it is characterized in that: the pitch of described spring body (1) diminishes to direction of both ends gradually by in the middle of the spring body.
