Embodiment
Embodiment of the present utility model is described below in detail, the example of the embodiment is shown in the drawings.Below by
The embodiment being described with reference to the drawings is exemplary, it is intended to for explaining the utility model, and it is not intended that new to this practicality
The limitation of type.
The Anti-looseness bolt device 10 according to the utility model embodiment is described in detail below with reference to Fig. 1-Fig. 8.
As shown in Fig. 1, Fig. 4 and Fig. 6, it can be included according to the Anti-looseness bolt device 10 of the utility model embodiment：Bolt
1st, packing ring 3 and the ratchet 2 and ratchet 4 that cooperate, packing ring 3 can be releasably set on bolt 1, in ratchet 2 and ratchet 4
One be fixedly installed on bolt 1, and another in ratchet 2 and ratchet 4 is fixedly installed on packing ring 3.That is,
When ratchet 2 is fixedly installed on bolt 1, ratchet 4 is fixedly installed on packing ring 3；When ratchet 2 is fixedly installed on packing ring 3,
Ratchet 4 is fixedly installed on bolt 1.
Wherein, by the cooperation between ratchet 4 and ratchet 2, it can make it that the circumferential clocking of turbine of packing ring 3 and bolt 1 is preferable,
So in the component vibration fixed by Anti-looseness bolt device 10, for example, part can be battery bag, when vehicle travels, electricity
Chi Bao can have Vibration Condition, and now, the ratchet 2 and ratchet 4 of mutual cooperation can effectively avoid bolt 1 from rocking caused screw thread
Wear and release phenomenon, so as to lift the fixation reliability of Anti-looseness bolt device 10, and check bolt dress can be extended
Put 10 service life.In addition, the Anti-looseness bolt device 10 being arranged such is simple in construction, easy to use, efficiency of assembling is high, cost
It is low.
It is described in detail below so that ratchet 2 is fixedly installed on bolt 1 and ratchet 4 is fixedly installed on packing ring 3 as an example.
As shown in Fig. 3, Fig. 5 and Fig. 7, packing ring 3 can include：Ring part 31 and extension 32, ring part 31 are set in spiral shell
On bolt 1, and extension 32 is connected to the outside of ring part 31, and extension 32 extends to radial outside, and ratchet 4 is connected to
Extension 32 is towards the side of ratchet 2.Specifically, so on the one hand can as shown in figure 1, ratchet 4 is located at the upside of extension 32
In order to the cooperation between ratchet 2 and ratchet 4, the fixation reliability between packing ring 3 and ratchet 4 on the other hand can be ensured.
Alternatively, packing ring 3 and ratchet 4 can be formed in one part, and bolt 1 and ratchet 2 can be formed in one part.Example
Such as, packing ring 3 and ratchet 4 can be integrated injection molding part, and bolt 1 and ratchet 2 can be integrated injection molding part.Above-mentioned portion
The injection material of part can be the materials such as nylon, PC plastic (makrolon), PP (polypropylene) and PVDF (Kynoar).And
And in order to increase intensity, glass fibre can be mixed.Thus, the Anti-looseness bolt device 10 made of above-mentioned at least one material
Applying has acid and alkali-resistance, anticorrosive in battery bag, and fire-protection rating is high, good insulation preformance and many advantages, such as light weight.
According to a specific embodiment of the present utility model, ring part 31 is provided with circumferential limit on the side away from ratchet 2
Position part, circumferential locating part are adapted to fit on the surface of fixture 7.Pass through the week between circumferential locating part and fixture 7
To spacing, so as to further avoid because bolt 1 loosens caused by vibration, it is ensured that the steadiness that bolt 1 connects.
Alternatively, as shown in Figure 4 and Figure 5, circumferential locating part can be helical teeth 5.The setting of helical teeth 5 can be effectively increased spine
Frictional force between the downside of wheel 2 and fixture 7, so as to avoid the rotation of packing ring 3 and bolt 1, and then can be protected
Demonstrate,prove the steadiness that bolt 1 connects.
Further, as shown in Figure 4 and Figure 5, helical teeth 5 can be multiple, and multiple helical teeth 5 are evenly distributed on ring part
On 31 side.By setting multiple helical teeth 5, the contact area between circumferential locating part and fixture 7 can be improved, can be with
So that synchronism is more preferable between packing ring 3 and fixture 7, bolt 1 can be preferably avoided to rotate and release.
Specifically, gradient of the helical teeth 5 on the side of ring part 31 is between 1 ° -2 °.Specifically, gradient can be
1.6 °, the reliability of helical teeth 5 being arranged such is preferable, and the circumference that can be effectively improved between packing ring 3 and fixture 7 is spacing
Ability.
Alternatively, as Figure 6-Figure 8, circumferential locating part can be projection 6 to another kind.It can be set on fixture 7
Fluted 8, projection 6 and groove 8 coordinate, and by the cooperation of projection 6 and groove 8, can effectively improve packing ring 3 and fixture 7
Between cooperation reliability, the rotation of bolt 1 can be avoided and released, thereby may be ensured that bolt 1 connect steadiness.
Alternatively, the free end of projection 6 can be circle.The projection 6 being arranged such preferably can coordinate with groove 8.
Alternatively, as shown in fig. 7, projection 6 is arranged on the position that ring part 31 faces with extension 32.Thus, projection 6
Position set suitable, extension 32 can play direction action at least to some extent, so as to reduce projection 6 and groove
8 cooperation difficulty.
In addition, when removing, only ratchet 4 need to outwards be ejected to the ratchet 2 being engaged with strength range, it is not necessary to
The original structure of 2 bolt of ratchet 1 is destroyed, dismounting loss can be so reduced, removal efficiency can be improved.
