Abstract
The utility model provides a locking structure of taking off of interior jump ring, this structure of includes interior axle, overcoat, spring, interior jump ring and locking ring etc. And interior axle is step cylinder shape structure, overlaps shock mount, locking ring in proper order at thinner interior shaft part, and spring one end is fixed through interior pillow block rank, at thicker interior shaft part suit overcoat, the overcoat tail end is equipped with jump ring groove, jump ring in the assembly of jump ring inslot, establish to ladder cylindrical structures locking ring outside, and thicker excircle section diameter is greater than jump ring internal diameter in the assembly back, and thinner excircle section diameter is lighter than jump ring internal diameter in the assembly back, interior jump ring assembly back, the spring is compression situation, and locking annular shaft pastes tight interior jump ring side to the step face, and the excircle section that locking ring is thinner stretches into in the interior jump ring hole. This structure can be eliminated the product and use the radial deformation space that the jump ring is caused by external force in, and the jump ring atress is out of shape the too big problem that comes off from the jump ring groove in avoiding using, improves the resistant mechanical environment performance of product and uses the reliability.
Description
Technical field
This utility model relates to jump ring anti-loose structure in one.
Background technology
Interior jump ring is part commonly used in product structure design, and it is typically used in two and is slidably matched between part axially solid
Determine and inner body occasion of axial restraint in cavity.During product uses, owing to External Force Acting causes by interior jump ring solid
There is axial deflection in fixed part, causes interior jump ring to be shunk by radial force, and when contraction distortion is excessive, interior jump ring can be from jump ring
Groove is deviate from, causes product quality problem.
Summary of the invention
The purpose of this utility model is to provide a kind of interior jump ring anti-loose structure, and this structure can be applicable to use interior jump ring to realize
The occasion of mating parts axial restraint, can solve the problem that interior jump ring is got loose by external force in product uses.
Jump ring anti-loose structure in the technical scheme is that one of this utility model, this structure include interior axle, overcoat,
Spring, interior jump ring and anti-DNA releaxed circular DNA etc., interior axle is stepped cylindrical shape structure, at thinner interior shaft part pocketed springs successively, locking
Ring, at thicker interior shaft part suit overcoat, described overcoat tail end is provided with jump-ring slot, jump ring in assembling in jump-ring slot.
Being set to ladder barrel shape structure outside described anti-DNA releaxed circular DNA, thicker cylindrical section diameter is interior jump ring internal diameter more than after assembling, relatively
Thin cylindrical section diameter less than jump ring internal diameter in after assembling, an anti-DNA releaxed circular DNA part can be made to stretch into interior jump ring endoporus and not from interior jump ring
Endoporus gets loose.It is provided with radial clearance between anti-DNA releaxed circular DNA endoporus and interior axle periphery, is provided with between anti-DNA releaxed circular DNA cylindrical and overcoat inner headed face
Radial clearance, can slide axially.
Described spring bores is equipped with radial clearance with interior axle periphery, spring cylindrical with overcoat inner hole surface, and spring vertically may be used
Freely to stretch；Spring one end is fixed by interior pillow block rank, and the spring other end is adjacent to anti-DNA releaxed circular DNA side, and spring is initially and is subject to
Pressure condition.
After described interior jump ring loads overcoat jump-ring slot, under spring axial compressive force, locking annulate shaft is to step surface and interior jump ring side
Being adjacent to, the cylindrical section that anti-DNA releaxed circular DNA is thinner extend in interior jump ring endoporus.
The beneficial effects of the utility model are, in using this utility model, jump ring anti-loose structure can eliminate during product uses interior
Emptying of the radial shape that jump ring is caused by external force, in solving during product uses, jump ring stress deformation is excessive from asking that jump-ring slot comes off
Topic, improves product resistance to mechanics environmental performance and dependability.
Accompanying drawing explanation
Fig. 1 is the structural representation of interior jump ring anti-loose structure of the present utility model
Axle, 2. overcoat, 3. spring in 1. in figure, 4. in jump ring, the most anti-DNA releaxed circular DNA.
Detailed description of the invention
In Fig. 1, interior axle (1) is stepped cylindrical shape structure, at thinner interior shaft part (12) pocketed springs successively (3), prevents
DNA releaxed circular DNA (5), at thicker interior shaft part (11) suit overcoat (2), thicker interior shaft part (11) diameter is more than spring (3)
Internal diameter, it is achieved spring (3) one end is fixed.Overcoat (2) tail end is provided with jump-ring slot (21), assembles in jump-ring slot (21)
Interior jump ring (4).It is matched in clearance between anti-DNA releaxed circular DNA (5) and interior axle (1) periphery and overcoat (2) inner headed face, spring (3)
And it is matched in clearance between interior axle (1) periphery and overcoat (2) inner headed face, it is ensured that anti-DNA releaxed circular DNA (5) and spring (3) are equal
Can the most slidably.Anti-DNA releaxed circular DNA (5) is outside is set to ladder barrel shape structure, and thicker cylindrical section (51) diameter is more than
Jump ring (4) internal diameter in after assembling, thinner cylindrical section (52) diameter is interior jump ring (4) internal diameter less than after assembling, it is ensured that interior
After jump ring (4) assembling, spring (3) and anti-DNA releaxed circular DNA (5) are limited between interior axle (1) step and interior jump ring (4).Bullet
Spring (3) is initially pressured state, and side is adjacent to anti-DNA releaxed circular DNA (5), under spring (3) axial compressive force, and anti-DNA releaxed circular DNA (5) axle
Being adjacent to interior jump ring (4) side to step surface, the cylindrical section (52) that anti-DNA releaxed circular DNA is thinner extend in interior jump ring (4) endoporus.
In use, spring (3) pressurized all the time, in spring one end holds out against anti-DNA releaxed circular DNA (5) and makes one part extend into this structure
In jump ring (4) endoporus, jump ring (4) radial deformation space in eliminating, it is to avoid interior jump ring is excessive from card by external force radial deformation
The problem of spring groove abjection, it is achieved product is interior jump ring anti-loose function in using.
