Detailed description of the invention
Below in conjunction with drawings and the specific embodiments, this utility model is described in further detail.
As in figure 2 it is shown, this utility model one structure for preventing plug from loose, including being placed between socket flange and socket screw thread
Floating bushing 1, as it is shown on figure 3, floating bushing 1 circumferentially has breach, make floating bushing 1 can have certain elasticity in radial direction,
Can rise after mouth through socket threaded portion, finally be placed between socket flange and socket screw thread, floating bushing 1 can be at socket flange
And move axially between screw thread.Also include being inserted in outside floating bushing 1 spring 2 being placed under floating bushing 1 end face step 1-1.Also
Including being placed in the circular arc projection 7 of socket flange, as shown in Figure 4, described circular arc projection 7 is inside the circular arc being perpendicular to flange direction
Center has a vertical slot 7-1, and has upper draw-in groove 3 and the lower bayonet slot 4 of the through hole form that is square, this circular arc in vertical slot 7-1
Projection 7 is placed in the middle of the screw mounting hole of flange, can avoid install time screw interference problem, vertical slot 7-1, upper draw-in groove 3 and under
The width of draw-in groove 4 is A, and the height of upper draw-in groove 3 and lower bayonet slot 4 is L.Also include that being placed in plug connects swivel nut top circumferentially
Uniform plug tooth-shape structure 5.Also include lock sleeve 6, as it is shown in figure 5, the endoporus of lock sleeve 6 with step 6-2 and with floating
The end face step 1-1 of set 1 forms matched in clearance；The top of lock sleeve 6 with the lock sleeve tooth-shape structure 6-3 being uniformly distributed along the circumference,
And form matched in clearance with plug tooth-shape structure 5；The bayonet lock 6-1 of lock sleeve 6 is placed in the cantilever end of lock sleeve 6, in radial direction side
To having certain elasticity, and formed during connector locking with upper draw-in groove 3, lower bayonet slot 4 and coordinate.The setting of vertical slot 7-1, makes
Even if obtaining bayonet lock 6-1 can not rotate when draw-in groove 3 and lower bayonet slot 4 on not falling within, it is ensured that bayonet lock 6-1 does not occurs when moving axially
Rotate；Bayonet lock 6-1 width A1 is less than A, forms width tolerance；Bayonet lock 6-1 height L1, less than draw-in groove height L, enables bayonet lock 6-1
Fall completely within draw-in groove 3 or draw-in groove 4.
When pin connector and the mutual timing of socket connector, for avoiding the lock sleeve tooth-shape structure 6-3 of lock sleeve 6 and being connected
The many toothings of plug 5 on swivel nut top interfere, and then affect threaded engagement, and the bayonet lock 6-1 of lock sleeve 6 need to be pressed into lower card
Groove 4, process is as follows: when being compressed to flange direction by lock sleeve 6, owing to the bayonet lock 6-1 front end of lock sleeve 6 is with chamfering, so
Draw-in groove in abjection 3 is moved by bayonet lock 6-1 to lower bayonet slot 4 direction, and meanwhile, lock sleeve 6 drives spring to be formed and is compressed axially, until card
Pin 6-1 falls in lower bayonet slot 4, owing to bayonet lock 6-1 rear end is right angle step, so bayonet lock 6-1 can be fixed stuck by lower bayonet slot 4.
Now can carry out the threaded engagement operation of socket and plug, as shown in Figure 6.
After pin connector and socket connector are at a fully engaged, use instrument presses bayonet lock 6-1, bayonet lock in radial direction
6-1 is stressed generation deformation, after abjection lower bayonet slot 4, makes bayonet lock 6-1 slide axially the axial force by spring, and finally falls
Entering in upper draw-in groove 3, the lock sleeve tooth-shape structure 6-3 of lock sleeve 6 will be formed with the plug tooth-shape structure 5 being connected swivel nut top simultaneously
Occlusion.Lock sleeve tooth-shape structure 6-3 should ensure that abundant quantity, at fixing circumference with the number of teeth of plug tooth-shape structure 5
Under degree, i.e. form less monodentate size, this monodentate should be made to be smaller in size than bayonet lock 6-1 and upper draw-in groove 3, the width appearance of lower bayonet slot 4
Difference, after the most sufficiently small monodentate size can ensure that bayonet lock 6-1 falls into draw-in groove 3, lock sleeve tooth-shape structure 6-3 ties with plug profile of tooth
Structure 5 automatic alignment.As shown in Figure 2.
In the bayonet lock 6-1 of lock sleeve 6 is placed in upper draw-in groove 3, lock sleeve 6 cannot rotate by counterpart receptacle, and due to lock sleeve 6
Engaged by tooth-shape structure with being connected swivel nut, so plug connects swivel nut and can not rotate by counterpart receptacle, avoiding problems
Connect getting loose of screw thread.
This connector anti-loose structure has higher reliability and facilitates the features such as operation, can be widely applied to requirement
The occasion being reliably connected, has wide market prospect.
