Description
Technical field
The invention belongs to spring technical field of measurement and test, be related specifically to a kind of spring and fixing device thereof.
Background technique
Spring all has a wide range of applications in a lot of occasion, such as, say Motor Vehicle, machinery equipment etc.In use can there is compression and tension in spring, therefore, the fixing of both ends of the spring must be firm, otherwise spring will be deviate from repeatedly.The occasion larger in space, fixing spring ratio is easier to, and can adopt welding, binding, but the occasion very little in space, such as toy car etc., because cannot adopt the means of fixation such as welding, the fixing of spring just difficult for very much.
Summary of the invention
The object of the invention is to propose a kind of spring and fixing device thereof, in small space, spring can be fixed very easily.
Spring of the present invention comprises spring body, key is that the two ends of described spring body are provided with disconnecting prevention structure, described disconnecting prevention structure comprises a main belleville spring and an attachment post, and one end of described attachment post is fixedly connected with the middle part of main belleville spring, and the other end is fixedly connected with spring body; The middle part of described main belleville spring is given prominence to towards the direction away from spring body.
The spring fitting device coordinated with above-mentioned spring that the present invention proposes comprises the mounting cylinder of an at least one end opening, and the inwall of described mounting cylinder is provided with annular groove; The internal diameter of mounting cylinder is less than the external diameter of described main belleville spring.
When mounting spring, as long as firmly by the main belleville spring press-in mounting cylinder of spring end, make the edge of winner's belleville spring snap onto in annular groove.When spring is subject to the pulling force away from mounting cylinder direction, main belleville spring will produce deformation under the effect of pulling force, because the middle part of main belleville spring is given prominence to towards the direction away from spring body, therefore under this pulling force effect, the external diameter of main belleville spring can become large, thus firmly snap onto in annular groove and cannot deviate from, so just can ensure the soundness of spring fitting.
Further, described disconnecting prevention structure also comprises an auxiliary belleville spring between main belleville spring and spring body, the middle part of described auxiliary belleville spring is provided with through hole, and described attachment post is through the through hole of this auxiliary belleville spring, and attachment post is fixedly connected with auxiliary belleville spring; The bending direction of auxiliary belleville spring is relative with the bending direction of main belleville spring; Deformation gap is left between described main belleville spring and auxiliary belleville spring.
In the spring fitting device coordinated with above-mentioned spring, described annular groove has two, and the spacing between two annular grooves equals described deformation gap.When mounted, respectively the edge of main belleville spring and auxiliary belleville spring is snapped onto in two annular grooves, like this when spring-compressed or when stretching, the external diameter that can ensure a belleville spring increases and prevents spring arbitrarily movement, achieves two-way fixing.
Spring of the present invention and fixing device thereof without the need to larger operating space, are very suitable for the applications such as toy car when mounted, have good practicability.
Accompanying drawing explanation
Fig. 1 is the spring of embodiment 1 and the structural representation of fixing device thereof.
Fig. 2 is the spring of embodiment 2 and the structural representation of fixing device thereof.
Accompanying drawing indicates: 1, spring body; 2, main belleville spring; 3, attachment post; 4, mounting cylinder; 5, annular groove; 6, auxiliary belleville spring.
Embodiment
Contrast accompanying drawing below, by the description to embodiment, the effect and working principle etc. of the specific embodiment of the present invention as the mutual alignment between the shape of involved each component, structure, each several part and annexation, each several part are described in further detail.
Embodiment 1:
As shown in Figure 1, the spring of the present embodiment comprises spring body 1, key is that the two ends of described spring body 1 are provided with disconnecting prevention structure, described disconnecting prevention structure comprises a main belleville spring 2 and an attachment post 3, one end of described attachment post 3 is fixedly connected with the middle part of main belleville spring 2, and the other end is fixedly connected with spring body 1; The middle part of described main belleville spring 2 is given prominence to towards the direction away from spring body 1.
The spring fitting device coordinated with above-mentioned spring comprises the mounting cylinder 4 of an at least one end opening, and the inwall of described mounting cylinder 4 is provided with annular groove 5; The internal diameter of mounting cylinder 4 is less than the external diameter of described belleville spring.
When mounting spring, as long as be firmly pressed in mounting cylinder 4 by the main belleville spring 2 of spring end, the edge of winner's belleville spring 2 is snapped onto in annular groove 5.When spring is subject to the pulling force away from mounting cylinder 4 direction, main belleville spring 2 will produce deformation under the effect of pulling force, because the middle part of main belleville spring 2 is given prominence to towards the direction away from spring body 1, therefore under this pulling force effect, the external diameter of main belleville spring 2 can become large, thus firmly snap onto in annular groove 5 and cannot deviate from, so just can ensure the soundness of spring fitting.
Embodiment 2:
As shown in Figure 2, the spring of the present embodiment comprises spring body 1, the two ends of described spring body 1 are provided with disconnecting prevention structure, described disconnecting prevention structure comprises main belleville spring 2, auxiliary belleville spring 6 and an attachment post 3, the central authorities of described auxiliary belleville spring 6 are provided with through hole, described attachment post 3 is through the through hole of auxiliary belleville spring 6, and attachment post 3 is fixedly connected with the middle part of main belleville spring 2, auxiliary belleville spring 6 respectively; The bending direction of described two belleville springs is relative, and leaves deformation gap between two belleville springs; The end, one end of described attachment post 3 is fixedly connected with spring body 1; Auxiliary belleville spring 6 is between main belleville spring 2 and spring body 1.
The spring fitting device coordinated with above-mentioned spring comprises the mounting cylinder 4 of an at least one end opening, and the inwall of described mounting cylinder 4 is provided with two annular grooves 5; And the spacing between two annular grooves 5 equals described deformation gap, the internal diameter of mounting cylinder 4 is less than the external diameter of described belleville spring.
When mounted, respectively main belleville spring 2 is snapped onto in two annular grooves 5 with the edge of auxiliary belleville spring 6, like this when spring-compressed or when stretching, the external diameter that can ensure a belleville spring increases and prevents spring arbitrarily movement, achieves two-way fixing.
