2. process plastic washer and spring washer：According to the outside diameter of screw, the mould of making plastic washer and spring washer,
Thin wire and synthetic resin are selected, punch forming is carried out, obtains finished plastic packing ring and spring washer；
3. machining support：The mould of stent is made, selects plastics to carry out plastic pressure forming, obtains finished product stent.
4. assemble screw, plastic washer, spring washer, stent：Spring washer is socketed on one end of screw nail capping, is made
Spring washer is located in the limited step of stent, inserts screws into the mounting hole of stent, and modeling is socketed in one end of screw thread
Backing strap circle, fixing screws and stent.
1. the step is divided into following steps：
(1.1) thin wire is put into the smelting furnace that temperature is 1800 degree and is melted；
(1.2) solution mould is poured into be molded；
(1.3) molding model is reprocessed by lathe car, miller sequence and tapping, obtains finished product screw.
2. the step is divided into following steps：
(2.1) according to the outside diameter of screw, the mould of plastic washer and spring washer is made；
(2.2) thin wire is put into the mould of plastic washer, synthetic resin is put into the mould of spring washer, is rushed
It is molded；
(2.3) molding model is carried out deburring, obtains finished plastic packing ring and spring washer.
The step 3. in plastics be 4344 plastics.
The beneficial effects of the present invention are：Stent, plastic washer, screw three are used cooperatively, and reach what anti-screw was scattered
Purpose, its is simple in structure, easy to implement, can effectively prevent screw and is scattered.

Embodiment
Be described further below technical scheme, but claimed scope be not limited to it is described.
As shown in Fig. 1,3,4, a kind of anti-screw is scattered structure, including screw 1 and stent 4；The stent 4 is equipped with installation
Hole and limited step, screw 1 are plugged in mounting hole；One end of the screw 1 is equipped with plastic washer 2, and the other end is equipped with spring
Packing ring 3, as shown in Figure 2；The spring washer 3 is located in limited step, makes to be fastened between product and screw 1, dismantled
Journey becomes simple and fast.
The spring washer 3 is arranged on one end of block, prevents screw 1 from rocking back and forth, and plastic washer 2 is arranged on the one of screw thread
End, selects the preferable plastic washer 2 of toughness, when ensureing that screw 1 penetrates, has certain deformation quantity, is unlikely to burst plastic washer
2, while also can guarantee that and be in close contact between plastic washer 2 and screw 1, to reach the effect for preventing that screw 1 from coming off.
The internal diameter of the plastic washer 2 is less than the outside diameter of screw 1, and less than 1mm, guarantee is acted on by slight external force,
Screw 1 can pass through the internal diameter of plastic washer 2, make 2 clamping stagnation of plastic washer on screw 1, have the function that anti-screw 1 is scattered.
The internal diameter of the mounting hole is less than the outside diameter of plastic washer 2.
It is scattered method based on a kind of anti-screw；Comprise the following steps：
1. process screw 1：Thin wire is selected, thin wire is put into the smelting furnace that temperature is 1800 degree and is melted, molten
Liquid pours into mould, is molded, and molding model is reprocessed by lathe car, miller sequence and tapping, obtains finished product spiral shell
Nail 1；
2. process plastic washer 2 and spring washer 3：According to the outside diameter of screw 1, plastic washer 2 and spring washer 3 are made
Mould, selects thin wire and synthetic resin, thin wire is put into the mould of plastic washer 2, synthetic resin is put into spring washer 3
Mould in, carry out punch forming, molding model carry out deburring, first examination processing several samples, if sample is in actual need
There is deviation, then mould is modified, if sample meet demand, finished plastic packing ring 2 and bullet can be obtained with batch machining
Spring packing ring 3；
3. machining support 4：The mould of stent 4 is made, selects 4344 plastics to carry out plastic pressure forming, obtains finished product stent 4.
4. assemble screw 1, plastic washer 2, spring washer 3, stent 4：Spring washer 3 is socketed in the one of 1 block of screw
On end, spring washer 3 is located in the limited step of stent 4, screw 1 is inserted into the mounting hole of stent 4, in 1 screw thread of screw
One end socket plastic washer 2, fixing screws 1 and stent 4, wear during plastic washer 2 without any special tool(s), directly
With hand, exert oneself slightly, 1 top of press-in screw, in securing bracket 4 afterwards, as screw 1 constantly enters mounting hole, modeling
Backing strap circle 2 can constantly be displaced downwardly to 1 bottom of screw, not only act as the effect that anti-screw 1 is scattered, and mechanical equipment is used, property
Can have no effect, in some special use environments, can effectively avoid screw 1 be scattered loss caused by peril and peace
Full hidden danger.
