Description
Technical field
The invention belongs to spring technical field of measurement and test, it is related specifically to a kind of spring and its fixing device.
Background technology
Spring suffers from be widely applied in many occasions, such as say motor vehicle, machinery equipment etc..Spring is using process
In can occur compression and tension repeatedly, therefore, the fixation of both ends of the spring must be secured, and otherwise spring will be deviate from.In space ratio
Larger occasion, fixed spring are easier, and welding, binding may be used, but in the very small occasion in space, for example joke
Has vehicle etc., because the fixed forms such as welding can not be used, the fixation of spring is with regard to extremely difficult.
Invention content
The purpose of the present invention is to propose to a kind of spring and its fixing device, can in small space by spring very easily
It is fixed.
The spring of the present invention includes spring body, and key is that the both ends of the spring body are equipped with disconnecting prevention structure, described
Disconnecting prevention structure includes a main disk spring and a connecting pole, and one end of the connecting pole and the middle part of main disk spring are fixed
Connection, the other end are fixedly connected with spring body；The direction that spring body is directed away from the middle part of the main disk spring protrudes.
The spring fitting device of the cooperation proposed by the present invention with above-mentioned spring includes the mounting cylinder of an at least one end open,
The inner wall of the mounting cylinder is equipped with annular groove；The internal diameter of mounting cylinder is less than the outer diameter of the disk spring.
When installing spring, as long as firmly will be in the main disk spring of spring end indentation mounting cylinder so that main dish bullet
The edge of spring snaps onto in annular groove.When pulling force of the spring by separate mounting cylinder direction, main disk spring will
Deformation is generated under the action of pulling force, the direction due to being directed away from spring body in the middle part of main disk spring protrudes,
The outer diameter of main disk spring can become larger under the pulling force effect, can not deviate to firmly snap onto in annular groove, thus
It can ensure the fastness of spring installation.
Further, the disconnecting prevention structure further includes an auxiliary dish between main disk spring and spring body
The middle part of spring, the auxiliary disk spring is equipped with through-hole, and the connecting pole passes through the through-hole of the auxiliary disk spring, and connects
Column is fixedly connected with auxiliary disk spring；Assist the bending direction of disk spring opposite with the bending direction of main disk spring；Institute
State main disk spring and auxiliary disk spring between there are deformation gaps.
With the spring fitting device of above-mentioned spring cooperation, the annular groove has two, and between two annular grooves
Spacing be equal to the deformation gap.When mounted, the edge of main disk spring and auxiliary disk spring is snapped onto two respectively
In annular groove, in this way when spring-compressed or stretching, it can ensure to increase and prevent there are one the outer diameter of disk spring
Spring arbitrarily moves, and realizes two-way fixation.
The spring and its fixing device of the present invention is not necessarily to larger operating space when mounted, is very suitable for toy car etc. and answers
With occasion, there is good practicability.
Description of the drawings
Fig. 1 is the spring of embodiment 1 and its structural schematic diagram of fixing device.
Fig. 2 is the spring of embodiment 2 and its structural schematic diagram of fixing device.
Attached drawing indicates：1, spring body；2, main disk spring；3, connecting pole；4, mounting cylinder；5, annular groove；6, it assists
Disk spring.
Specific implementation mode
Below against attached drawing, by the description to embodiment, for example involved to the specific implementation mode of the present invention is each
Mutual alignment and connection relation, the effect of each section and operation principle between the shape of component, construction, each section etc. are made into one
The detailed description of step.
Embodiment 1：
As shown in Figure 1, the spring of the present embodiment includes spring body 1, key is that the both ends of the spring body 1 are equipped with
Disconnecting prevention structure, the disconnecting prevention structure include a main disk spring 2 and a connecting pole 3, one end of the connecting pole 3 and main dish
The middle part of shape spring 2 is fixedly connected, and the other end is fixedly connected with spring body 1；The middle part of the main disk spring 2 is directed away from
The direction of spring body 1 protrudes.
Spring fitting device with the cooperation of above-mentioned spring includes the mounting cylinder 4 of an at least one end open, the mounting cylinder 4
Inner wall be equipped with annular groove 5；The internal diameter of mounting cylinder 4 is less than the outer diameter of the disk spring.
When installing spring, as long as firmly the main disk spring 2 of spring end is pressed into mounting cylinder 4 so that main dish
The edge of spring 2 snaps onto in annular groove 5.When pulling force of the spring by separate 4 direction of mounting cylinder, main disk spring
2 will generate deformation under the action of pulling force, since the direction that the middle part of main disk spring 2 is directed away from spring body 1 protrudes,
Therefore the outer diameter of main disk spring 2 can become larger under the pulling force effect, can not be taken off to firmly snap onto in annular groove 5
Go out, ensures that the fastness of spring installation in this way.
Embodiment 2：
As shown in Fig. 2, the spring of the present embodiment includes spring body 1, the both ends of the spring body 1 are equipped with anticreep knot
Structure, the disconnecting prevention structure include main disk spring 2, assist disk spring 6 and a connecting pole 3, the auxiliary disk spring 6
Center is equipped with through-hole, and the connecting pole 3 passes through the through-hole of auxiliary disk spring 6, and connecting pole 3 respectively with main disk spring 2, auxiliary
The middle part of disk spring 6 is helped to be fixedly connected；The bending direction of described two disk springs is opposite, and is stayed between two disk springs
Tangible Varied clearance；One end end of the connecting pole 3 is fixedly connected with spring body 1；Disk spring 6 is assisted to be located at main dish-shaped bullet
Between spring 2 and spring body 1.
Spring fitting device with the cooperation of above-mentioned spring includes the mounting cylinder 4 of an at least one end open, the mounting cylinder 4
Inner wall be equipped with two annular grooves 5；And the spacing between two annular grooves 5 be equal to the deformation gap, mounting cylinder 4 it is interior
Diameter is less than the outer diameter of the disk spring.
When mounted, main disk spring 2 and the edge of auxiliary disk spring 6 are snapped onto in two annular grooves 5 respectively,
In this way when spring-compressed or stretching, it can ensure to increase there are one the outer diameter of disk spring and prevent spring from arbitrarily moving,
Realize two-way fixation.
