Specific embodiment
As shown in accompanying drawing 1,2.A kind of anti-explosion movable joint, including the first joint 10, the connection that is arranged on the first joint 10
The second joint 30 that nut 20 is threadedly coupled with attaching nut 20, be arranged at it is close between the first joint 10 and the second joint 30
Seal washer 40.
In this example, the first joint 10 is the power connection being connected with power end, and the second joint is to be connected with light fixture
Lamp joint 30.
As shown in Fig. 2 the first joint 10 includes the first joint body 11, one end edge part footpath by the first joint body 11
To the connection wall 12 for extending inwardly to form, the connection neck being extending axially outward form by the end of the connection wall 12 for extending out
13rd, extended radially outwardly the joint clasp 14 for being formed by the end of connection neck 13, the one end of attaching nut 20 have radially to
Interior to extend the nut snap ring 21 for being formed, nut snap ring 21 is sheathed on connection neck 13, and nut snap ring 21 and joint clasp 14
Mutually hook, so that attaching nut 20 can not be separated with the first joint 10.Between joint clasp 14 and connection wall 12 or joint card
Annular groove is formed between the end of the joint body 11 of ring 14 and first, nut snap ring 21 is inserted in annular groove.
Attaching nut 20 includes the female nut body 23 of tool, inner ring face can be tight with the edge part of seal washer 40
The nut extruded segment 22 of cooperation, nut extruded segment 22 is connected between nut snap ring 21 and nut body 23.Nut extruded segment 22
Internal diameter less than nut body 23 internal diameter.Namely nut extruded segment 22 and nut body 23 form platform between inner surface
Rank.In order that the outer peripheral surface of seal washer 40 and the inner peripheral surface clamping of nut extruded segment 22, are in order at the purpose for being easy to assembling.Such as
Shown in accompanying drawing 3, the formation on step between nut extruded segment 22 and nut body 23 is that the outer surface of nut extruded segment 22 is subject to
Extruding is led everywhere so as to deforming, during installation, by the corresponding annular groove of nut snap ring 21, to the outer surface of nut extruded segment 22 radially-inwardly
Extruding deforms it, is allowed in the insertion annular groove of nut snap ring 21, and nut snap ring 21 is mutually hooked with joint clasp 14.
Second joint 30 is including the joint linkage section 32 for being mutually threadedly coupled with attaching nut 20, positioned at the second joint 30
One end and abutting joint linkage section 32 push against end 31, the back-up ring 33 positioned at the other end of joint linkage section 32, positioned at the
The other end of two joint 30 and the second joint body 34 of adjacent back-up ring 33.
Seal washer 40 clamps connection neck 13, the abutting of the joint 30 of joint clasp 14 and second for being arranged at the first joint 10
Between end 31.When Product Assembly, it is necessary to attaching nut 20 is separated with the second joint, and when now backing out, due to sealing gasket
Circle 40, by the presence of pushing against end 31, is squeezed in nut extruded segment 22 previously, is difficult to drop out, so that convenient install.
The characteristics of using the first joint and constant the second nipple orifice internal diameter, connection wall, connection neck and joint clasp can be right
The standard value of hole internal diameter is answered, corresponding attaching nut can also take standard value, so as to greatly save production material, and reduce production
Cost.
As above, we are illustrated fully according to spirit of the invention, but the present invention is not limited to above-described embodiment
And implementation.The practitioner of correlative technology field can carry out different changes in the range of technological thought of the invention license
And implement.
