Detailed description of the invention
The utility model is described in further detail with embodiment below in conjunction with the accompanying drawings, but not as new to this practicality
Any restriction of type.
A kind of molectron being realized locking function by screw, as it is shown in figure 1, include screw 1 and inner thread part 2, spiral shell
Nail 1 is provided with external screw thread 3, and inner thread part 2 is provided with screwed hole 4；The complete thread of at least 6 times of pitch in screwed hole 4.Spiral shell
Screw thread in pit 4 is coarse thread or fine thread, and the grade of tolerance of coarse thread is 5H6H, the grade of tolerance of fine thread
For 6H.The aperture of screwed hole 4 is provided with chamfering 11, and the diameter Da of chamfering 11 is at least bigger 0.4mm than Major Diam D.The angle of chamfering 11
Degree is 90～120.External screw thread 3 is that starting point is followed successively by screw-in section 5, locking section 6, reserved section 7 and screw thread by screw 1 end face
Changeover portion 8；Locking section 6 is provided with groove 9, is provided with latch segment 10 in groove 9.Screw in the length of section 5 at least equal to 2 times of pitch.Lock
The minimum length of tight section 6 is 5 times of pitch.The greatest length of locking section 6 for screw between section 5 to screw thread changeover portion 8 all completely
The total length of screw thread.The (see figure 2) generally circular in shape of groove 9, oval (see figure 3), Long Circle (see figure 4), prismatic (see figure 5)
Or rectangle (see figure 6), the shape of latch segment 10 is corresponding with the shape of groove 9.Latch segment 10 is embedded or pouring-in nylon system
Part；Nylon material is: nylon 1010 or anti-aging nylon F-6601.
Embodiment
When being embodied as, it is when processing screw or bolt, the screw rod of screw or bolt is processed a groove 9, so
After in groove 9, inlay one piece of latch segment, latch segment uses plasticity preferable as far as possible, and coefficient of friction is relatively big, and has some strength
Material make, when screw or bolt are threaded into hole, latch segment can produce certain deformation, closely cooperates with female thread
Produce coupling mechanism force.
Latch segment in this example uses nylon material, the nylon 1010 in concrete optional HG2-869 or selection Q/
Black anti-aging nylon F-6601 in HG179.Specifically adding man-hour, groove preferably band point dovetail shaped, to prevent latch segment from recessed
Groove is deviate from.The shape of groove can be processed into the different shapes such as circle, ellipse, Long Circle, prismatic or rectangle as required
Shape.The shape of latch segment should be corresponding with the shape of groove, latch segment can be pre-fabricated after be pressed into groove, it is also possible to pass through
Injection molded, is directly injected into groove.It is too many that latch segment can not exceed screw thread, after latch segment installs, should be checked by ring gauge, should
Bolt or screw can be made freely through the ring gauge of predetermined diameter by means of the pressure of finger.Latch segment installation position on screw rod
Put and can determine as required, in general, reach on screw rod can be divided into screw-in section as shown in Figure 1, locking section, pre-
The section of staying and screw thread changeover portion, wherein screw thread changeover portion is the length that screw thread itself has, when screw thread determines rear thread changeover portion one
As be changeless.Latch segment is definitely to be arranged on screw thread changeover portion.Remaining length of each section can be the most true
Fixed, latch segment should be arranged in locking segment limit.This example pair also there are certain requirements with the screwed hole of screw or bolt matching.Screw thread
The grade of tolerance (coarse thread 5H6H, closely-pitched 6H) higher for Kong Yingyou, screwed hole length should ensure that the complete spiral shell of at least 6 times of pitch
Stricture of vagina.Screwed hole on inner thread part bearing-surface must be shaped with chamfering, and chamfering diameter Da is at least bigger 0.4mm than Major Diam.
This utility model is mainly applied on the product of space flight, aviation field.Owing to this product has been worn certainly relative to needs
For the self-locking nut of lock function just can be produced from lock function assembling, clamping screw, screw product are easier to processing, manufacturing cost
Less expensive, therefore, is worth the product of other industry field to use, is worthy to be popularized.
