Advantages and features of the invention will become apparent from.It should be noted that attached drawing is all made of very simplified form and using non-accurate
Ratio, only for the purpose of facilitating and clarifying the purpose of the embodiments of the invention.
It is as described in the background art, existing eccentric spring in the installation process of mechanism, need to pre-tighten in order to provide
The initial holding force of mechanical structure.Spring is right because the stress of itself, is easy to jump out, causes failure mechanisms in this process
In operator and security risk.
Therefore, in Design of Mechanical Structure technical field, to solve the above-mentioned problems, the present invention provides a kind of eccentric springs
Mechanism.
Refering to fig. 1, Fig. 1 is the fractionation structural representation of over-center spring mechanism provided in an embodiment of the present invention.
Specifically, as shown in Figure 1, the over-center spring mechanism includes eccentric spring 11, eccentric wheel 12, shell 13 and lid
Plate 14；Wherein, the eccentric spring 11 have the first spring leg 11a and second spring leg 11b, the first spring leg 11a and
The second spring leg 11b is directed toward same direction, and the end of the first spring leg 11a is equipped with bending 11c.
Further, with continued reference to Fig. 1 and Fig. 2, the eccentric wheel 12 is equipped with the first mounting hole 12a, the shell 13
It is equipped with the second mounting hole 13a；The first spring leg 11a passes through the first mounting hole 12a and is arranged in the eccentric wheel 12
On；The second spring leg 11b passes through the second mounting hole 13a and is arranged on the shell 13.
Further, refering to fig. 1, the angle between the bending 11c and the first spring leg 11a pointing direction is less than
Equal to 45 °.In one embodiment, the angle between the bending and the first spring leg pointing direction can be 30 °,
35 °, 40 °.
Further, the eccentric spring includes torsionspring.
Further, refering to fig. 1 and Fig. 2, the center of the eccentric wheel 12 is equipped with a connecting hole 12b, on the shell 13
Equipped with a connecting shaft 13b；The connecting hole 12b, which is nested on the connecting shaft 13b, makes the eccentric wheel 12 and the shell 13
Connection.Further, the connecting shaft 13b is fixed on the shell 13, the connecting hole 12b and the connecting shaft 13b
Rotation connection, so that the eccentric wheel 12 can be rotated around the connecting shaft 13b.
Further, second mounting hole is blind hole.
Further, the cover board is mounted on the eccentric wheel, when first spring leg and the second spring
After leg is installed, the cover board is installed.
In one embodiment, the eccentric spring can be torsionspring, first spring leg and second bullet
The direction of spring leg meaning can be straight down, the angle between the bending and vertically downward direction of the end of first spring
Less than or equal to 45 °, such as it can be 30 °, 35 °, 40 °；First mounting hole can be through-hole, and second mounting hole can be with
For blind hole.
Specifically, refering to fig. 1 and Fig. 2, the installation process of the over-center spring mechanism are as follows: first will be in the eccentric wheel 12
The connecting hole 12b of heart setting is nested on the connecting shaft 13b of the shell 13, makes the eccentric wheel 12 and 13 phase of shell
Even.Then the first spring leg 11a of eccentric spring 11 is inserted into the first mounting hole 12a, is mounted on eccentric wheel 12；It will be eccentric
The second spring leg 12b of spring 11 is inserted into the second mounting hole 12b, is mounted on shell 13.Refering to Fig. 3, as in the direction A-A
Shown in cross-sectional view, due to the limitation of the first spring leg 11a and the second spring leg 11b direction d, it is located at the first installation
The bending place of the bending 11c at the hole back side 12a can resist the first mounting hole 12a, prevent the first spring pin 11a from the first mounting hole
Deviate from 12a, so as to avoid in subsequent installation process, eccentric spring 11 is because the elastic force of itself is jumped from mechanism
Out.After two spring pins are installed, cover board 14 is finally installed on eccentric wheel 12, then the over-center spring mechanism installs
At.
In conclusion in over-center spring mechanism provided by the invention, comprising: eccentric spring, eccentric wheel, shell and lid
Plate；The eccentric spring has the first spring leg and second spring leg, and first spring leg and the second spring leg are directed toward
The end of same direction, first spring leg is equipped with bending.The two of the eccentric spring of over-center spring mechanism provided by the invention
Spring leg is directed toward same direction and the end of the first spring leg is equipped with bending, is installing the first spring pin and second spring foot
Afterwards, before installing cover board, due to the limitation in two spring pin directions, the bending of the first spring leg end can prevent the first spring
Leg is deviate from from mounting hole, thus can be to avoid spring because the elastic force of itself is jumped from mechanism in subsequent installation process
Out, the manufacturability of mechanism is improved.
