Description
Technical field
The utility model belongs to nut applied technical field, refers in particular to a kind of just installation pressure-bearing self-tightening type nut.
Background technique
In modern industry field, nut is largely used to locking mechanism part, but is especially applied in many cases,
Under vibrational state, needs to carry out periodic inspection reinforcing to the structural member locked, prevent because of nut loosening bring structure
Dislocation, therefore, the fastening locking under many vibration environments have been applied to self-tightening nut, and still, self-tightening nut is in installation process
In, since self-tightening nut and self-tightening washer are metal structure, carried out in fastener cycle in nut, construction personnel may be due to
Excessive rotating nuts, excessive pressure may cause the anti-loose structure between nut and washer and generates damage, meanwhile, nut is big
It can only mostly be rotated by the spanner of certain fixing model, if not carrying the spanner of respective model when construction, work progress can be made
At delay.
Summary of the invention
In view of the deficienciess of the prior art, a kind of the purpose of the utility model is to provide load performances good, portable installation
Self-tightening type nut.
Purpose of the utility model is realized as follows: a kind of just install pressure-bearing self-tightening type nut, including nut and self-tightening
Washer, the nut are located at self-tightening bead top, and the nut includes the first parent, and the is provided at the top of first parent
Two parents, the second parent top are provided with third parent, and the outer diameter of first parent, the second parent and third parent is each
Not identical, the self-tightening bead interior is inlaid with pressure-bearing pad, and the pressure-bearing pad extends to self-tightening washer face, the self-tightening
Upper surface of washer edge is provided with ring set, and the internal diameter of ring set is matched with the first parent.
The utility model advanced optimizes are as follows: the atop part that the pressure-bearing pad is located at self-tightening washer face is provided with slow
Pressure pad.
The utility model advanced optimizes are as follows: the slow pressure pad is rubber pad.
The utility model advanced optimizes are as follows: the ring set is structure as a whole with self-tightening washer.
The utility model advanced optimizes are as follows: the self-tightening washer bottom, which is provided with, is circumferentially uniformly distributed groove.
The utility model advanced optimizes are as follows: the first parent, the second parent and the third parent outer diameter is sequentially reduced.
Compared with the prior art, the utility model has prominent and beneficial technical effects that: the pressure-bearing pad of the utility model can be prevented
Only nut stress is excessive and damage to washer, and the parent of multiple outer diameters, applicable a variety of different models are provided on nut
Spanner, facilitate installation.
Detailed description of the invention
Fig. 1 is the structural schematic diagram of the utility model；
Fig. 2 is the top view of the utility model.
In figure: 1- self-tightening washer, the first parent of 2-, the second parent of 3-, 4- third parent, 5- pressure-bearing pad, 6- groove, 7-
Ring set, 8- delay pressure pad.
Specific embodiment
The utility model is further described with specific embodiment with reference to the accompanying drawing, referring to Fig. 1-2: one kind is just pacified
Pressure-bearing self-tightening type nut, including nut and self-tightening washer 1 are filled, the nut is located at 1 top of self-tightening washer, the nut installation
In on self-tightening washer 1, the nut includes the first parent 2, is provided with the second parent 3 at the top of first parent 2, and described the
Third parent 4 is provided at the top of two parents 3, first parent 2, the second parent 3 and third parent 4 are structure as a whole, and
First parent 2, the second parent 3 and 4 outer diameter of third parent are sequentially reduced, and using this structure, multiple outer diameters are provided on nut
Parent, the spanner of applicable a variety of different models, facilitates installation.
In the present invention, 1 inside of self-tightening washer is provided with self-tightening mechanism with 2 junction of the first parent, described
Self-tightening washer 1 inside be inlaid with pressure-bearing pad 5, the pressure-bearing pad 5 extends to 1 surface of self-tightening washer, and the pressure-bearing pads 5
Atop part in 1 surface of self-tightening washer is provided with slow pressure pad 8, and the slow pressure pad 8 is rubber pad.Using this structure, can subtract
Pressure between slow nut and self-tightening washer 1, the self-tightening mechanism between effective protection nut and self-tightening washer 1, meanwhile, rubber material
The slow pressure pad 8 of material can further slow down pressure, while increase the frictional force between nut and self-tightening washer 1, further increase spiral shell
Stability after mother's installation.
In this reality specific embodiment, the 1 upper surface edge of self-tightening washer is provided with ring set 7, the internal diameter of ring set 7
It is matched with the first parent 2, ring set 7 is sheathed on around the first parent 2, can be by the self-tightening mechanism between nut and self-tightening washer 1
Sealing, prevents self-tightening mechanism from getting rusty locked.
The utility model advanced optimizes as 1 bottom of self-tightening washer, which is provided with, is circumferentially uniformly distributed groove 6, can
Increase self-tightening washer 1 and the frictional force between workpiece is installed, the stability after promoting installation.
Above-described embodiment is only the preferred embodiment of the utility model, not limits the protection model of the utility model according to this
It encloses, therefore: the equivalence changes that all structures, shape, principle according to the utility model are done should all be covered by the protection of the utility model
Within the scope of.
