Description
Technical field
The utility model is related to component of machine fields, and in particular to a kind of bullet is not easy the shrapnel of deviation.
Background technology
Shrapnel is for the instrument in machinery, the buffer anti-seismic device of vehicle and relay deferred mount, and the characteristics of shrapnel is,
It is only easily bent in minimum rigidity plane in one direction, and there is big tensible rigidity and bending in the other directions just
Degree.Therefore, flat spring is very suitable is used for doing detection instrument or sensing element in automatic device, elastic bearing, positioning device, scratch
Property connection etc..
Existing shrapnel is because of drum after punching press, plating, and paper tape friction bullet, under external force effect, bullet is to a direction
Crooked, bullet is inconsistent to two hem width degree of safe edge when slight, and bullet ear can not clasp safe edge when serious, withstands on one side safe edge
On.Why existing shrapnel can make bullet crooked after stressBecause bullet size 0.65-0.70mm, safe edge internal diameter
, there are about 0.15mm gaps in 0.9mm, when unilateral limit, and operating range is larger.External force is caused to act on and being plastically deformed causes bullet askew
Tiltedly.Why bullet understands stressIt after shrapnel drum, carries, the vibrations in transportational process easily make material strip and paper tape is generated and rubbed
It wipes, makes bullet stress.Make bullet crooked after stress so as to cause shrapnel, influence normal use.
Utility model content
In order to solve the above technical problems, we have proposed the shrapnel that a kind of bullet is not easy deviation, avoid shrapnel carry,
Vibrations in transportational process make bullet stress, and shrapnel is caused to make the crooked deviation of bullet after stress.
In order to achieve the above objectives, the technical solution of the utility model is as follows：
A kind of bullet is not easy the shrapnel of deviation, including main part, bullet, two panels earflap and two panels hook；The two panels shield
Ear is respectively arranged at main part one end both sides, and the two panels hook is connected on the inside of the earflap upper end, and towards in main part
Portion extends, and bottom is buckled in main part upper end two sides, and the main part other end is arc elastic structure, the bullet
Head is connected to above described main part one end, and upwardly extends the arc-shaped lapel shape in its rear end, and the bullet heel is broadened
It handles to 0.8 ± 0.05mm, and the gap between bullet heel and the earflap of both sides is not more than 0.05mm, the main part and institute
Bullet junction is stated in up-narrow and down-wide shape, and is thickened processing.
Preferably, the main part and the arc-shaped structure in bullet junction front.
Preferably, the main part is equipped with support portion with the positive Middle face in bullet junction.
Through the above technical solutions, the utility model is by by bullet heel widening treatment to 0.8 ± 0.05mm, and bullet
Gap between heel and the earflap of both sides is no more than 0.05mm, and the main part is with the bullet junction in up-narrow and down-wide
Shape, and it is thickened processing.Avoiding vibrations of the shrapnel in carrying, transportational process makes bullet stress, leads to shrapnel in stress
After make the crooked deviation of bullet, enable shrapnel normal use, reduce fraction defective, so as to reached it is novel in design, rational in infrastructure,
And the purpose of good application effect.
Description of the drawings
It in order to illustrate the embodiment of the utility model or the technical proposal in the existing technology more clearly, below will be to embodiment
Or attached drawing needed to be used in the description of the prior art is briefly described, it should be apparent that, the accompanying drawings in the following description is only
It is some embodiments of the utility model, for those of ordinary skill in the art, in the premise not made the creative labor
Under, it can also be obtained according to these attached drawings other attached drawings.
Fig. 1 is not easy the side view of the shrapnel of deviation for a kind of bullet disclosed in the utility model embodiment；
Fig. 2 is not easy the front view of the shrapnel of deviation for a kind of bullet disclosed in the utility model embodiment.
Corresponding component title of the number represented by with letter in figure：
1. 4. hook of main part 2. bullet, 3. earflap, 5. support portion
Specific embodiment
The following is a combination of the drawings in the embodiments of the present utility model, and the technical scheme in the embodiment of the utility model is carried out
It clearly and completely describes, it is clear that the described embodiments are only a part of the embodiments of the utility model rather than whole
