Abstract
The utility model provides a combined nut, include: nut body, taper washer and nylon ring, wherein, the first end of nut body with the taper washer riveting, the nylon ring embedding the second end of nut body. The utility model discloses structurally neither destroy outer threaded surface coating, again the high -efficient locking performance that promotes.
Description
Technical field
This utility model relates to fastening structure technical field, particularly to a kind of combination nut.
Background technology
Now, blank is carried out cold-heading by the mould on nut many employings cold headers on market, tapping is made, and this kind of nut structure is single, and the locking pretensioning capacity of nut itself is poor, especially when connecting portion surface quality is poor and bottom outlet is bigger, the artificial packing ring that increases is needed to solve.
Although all-metal locking nut has locking effect, but its head construction is pressure point or ellipse, external screw thread there is injury, externally threaded face coat can be wiped off, reduce externally threaded anti-corrosion capability, flange surface nut can destroy connecting end surface quality when assembling simultaneously, and coefficient of friction increases, and the clamping force in the generation of identical assembling moment of torsion diminishes and occurs loosening.
Utility model content
This utility model provides a kind of combination nut, its purpose is to solve nut of the prior art and causes external screw thread and scrape damage and destroy assembly connection face quality and cause loosening problem.
In order to achieve the above object, embodiment of the present utility model provides a kind of combination nut, including: nut body, taper washer and nylon ring；Wherein,
First end of described nut body rivets with described taper washer；
Described nylon ring embeds the second end of described nut body.
Preferably, described nut body is provided with the first boss, and described first boss is that the first end of nut body radially extends formation at inwall.
Preferably, the inner ring at described taper washer is provided with the groove matched with described first boss.
Preferably, described nut body is riveted with described taper washer at described taper washer groove by described first boss.
Preferably, described nut body is additionally provided with the second boss, and described second boss is the second end of described nut body fluting at inwall radially.
Preferably, described nylon ring embeds in the second boss of described nut body, and is connected with described nut body.
Such scheme of the present utility model has a following beneficial effect:
(1) taper washer in such scheme is taper, and on the one hand it improve the locking property of nut, on the other hand effectively reduces the contact area of packing ring and assembly connection end face, it is to avoid make coefficient of friction increase because of the abrasion of assembling contact surface.
(2) in such scheme, taper washer rivets with nut body, and taper washer can be freely rotatable with nut body, this mode makes during assembling, taper washer will not rotate along with the rotation of nut, so the clamping force that its assembling moment of torsion produces can not be affected by connecting end surface quality, some position that connecting end surface surface quality is very poor can be used for by emphasis.
(3) in such scheme, nut body embeds nylon ring, on the one hand improve the locking property of nut, on the other hand nylon ring also has excellent impact resistance and resistance to vibration, compared with nut of the prior art, external screw thread is not injured, externally threaded face coat will not be wiped off, it is ensured that externally threaded anti-corrosion capability.

Detailed description of the invention
For making the technical problems to be solved in the utility model, technical scheme and advantage clearer, it is described in detail below in conjunction with the accompanying drawings and the specific embodiments.
As depicted in figs. 1 and 2, embodiment of the present utility model provides a kind of combination nut, including: nut body 1, taper washer 2 and nylon ring 3；Wherein, the first end of nut body 1 rivets with taper washer 2；Second end of described nylon ring 3 inserted num body 1.This embodiment solve nut of the prior art external screw thread is caused scrape damage and destroy assembly connection face quality and cause loosening problem.
Further, as shown in Figure 3 and Figure 4, for the structural representation of nut body 1.Nut body 1 is provided with the first boss 4, and the first end that the first boss 4 is nut body 1 radially extends formation at inwall.As shown in Figure 5 and Figure 6, for the structural representation of taper washer 2.Inner ring at taper washer 2 is provided with the groove matched with described first boss 4.Nut body 1 is riveted with taper washer 2 at taper washer 2 groove by the first boss 4.
Specifically, nut body 1 is to be formed by cold headers upsetting system, by the machined taper washer 2 completed (if there being requirement of strength, thermally processable HRC40～48) it is set on the first boss 4 of nut body 1, then rivet, and ensure riveting after can be freely rotatable between taper washer 2 and nut body 1.So during assembling, taper washer 2 will not rotate along with the rotation of nut body 1, so the clamping force that its assembling moment of torsion produces can not be affected by connecting end surface quality, can be used for some position that connecting end surface surface quality is very poor by emphasis.
Further, as shown in Figure 3 and Figure 4, nut body 1 is additionally provided with the second boss 5, and the second boss 5 is the second end of nut body 1 fluting at inwall radially.In second boss 5 of nylon ring 3 inserted num body 1, and it is connected with nut body 1.
In this embodiment, being embedded by nylon ring 3 in the second boss 5 being arranged on nut body 1, nylon ring 3 can play the effect of fastening further, can prevent again external screw thread from wearing and tearing.
The combination nut of such scheme had both had the fastening function of conventional nut, possess again taper washer 2 and the function of nylon ring 3 (life-span-50 DEG C～100 DEG C), especially during assembling, the clamping force that its assembling moment of torsion produces can not be affected by connecting end surface quality.It the most neither destroys external threaded surface coating, the most efficiently promotes locking property.
The above is preferred implementation of the present utility model; it should be pointed out that, for those skilled in the art, on the premise of without departing from principle described in the utility model; can also make some improvements and modifications, these improvements and modifications also should be regarded as protection domain of the present utility model.
