[specific embodiment]
The nut inner thread protective device, extremely shown in Figure 12 such as Fig. 1, when being mainly used in the air-conditioning production and assembly and removing new clothes in order to keep the air-conditioning air-tightness and to prevent the air conditioner connecting pipe place that dust enters, nut 1 inner chamber of this device is provided with the tubulose skirt cover 2 that has certain interval with its negative thread, the shirt rim 20 of tubulose skirt cover 2 is nested in the outer end of nut 1, tubulose skirt cover 2 inside be the round empty cavity 21 with the nut concentric, evenly are provided with four ends on tubulose skirt cover 2 and the nut 1 negative thread inner chamber mating part and are connected in the tubulose skirt and overlap on 2 and the other end is free-ended distending sheet 22; Be provided with a relief groove 3 in nut 1 negative thread inside top, the free end top outer of each distending sheet 22 is provided with the projection 220 that can embed relief groove 3, and the inboard of each distending sheet 22 is provided with the block 221 that stretches into round empty cavity; Be combined with rib axle knob 4 in the round empty cavity 21 of tubulose skirt cover 2, be provided with on rib axle 41 tops of rib axle knob 4 and overlap 2 latches with the tubulose skirt and cooperates also rotatable bearing pin 5; The whole tubulose skirt of knob end 40 shutoff of rib axle knob 4 overlaps 2 ports, the rib axle 41 of rib axle knob 4 be provided with all distending sheets 22 on block 221 between the distending rib 410 that cooperates respectively of the endplay that forms, extremely shown in Figure 12 such as Fig. 9, when rib axle knob 4 turns an angle, distending rib 410 on the rib axle knob 4 promotes block 221 makes the projection 220 on distending sheet 22 free ends embed relief groove 3, the tubulose skirt is overlapped 2 sealing shrouds be connected on the nut 1; Like this, make between nut 1 relief groove 3 on tubulose skirt cover 2 and the air conditioner connecting pipe and be in tightr swelling state, and tubulose skirt cover 2 also keeps certain gap with nut 1 negative thread inner chamber mating part, keeping air conditioner connecting pipe to have dust-proof effect simultaneously, can't damage the negative thread of nut 1.
Wherein, described nut 1 is copper nut, tubulose skirt cover 2 elastic bodys that are one of the forming, the hard moulding that rib axle knob 4 is one of the forming.
As shown in Figure 5, also be provided with the swivelling chute 23 of knob handle 42 anglecs of rotation of control rib axle knob 4 on the tubulose skirt cover 2, knob handle 42 anglecs of rotation that concrete swivelling chute 23 limits rib axle knob 4 are 45 °, closely tension force is maximum between nut 1 relief groove 3 on tubulose skirt cover 2 and the air conditioner connecting pipe at this moment, and the swelling effect is best.
During assembling, first rib axle knob 4 is put in the tubulose skirt cover 2, cooperated compact; Then, the tubulose skirt cover 2 that assembles is put in the copper nut 1, in the swivelling chute 23 of tubulose skirt cover 2, the knob handle 42 of rotation rib axle knob 4 reaches 45 °, distending rib 410 on the rib axle 41 rotates with rib axle knob 4, distending rib 410 promotes the block 221 of distending sheet 22 and makes distending sheet 22 distendings, and the projection 220 on distending sheet 22 free ends embeds in the relief groove 3, the tubulose skirt is overlapped 2 sealing shrouds be connected on the nut 1; During dismounting, only need the knob handle 42 of reverse 45 ° of rotation rib axle knobs 4, allow 4 pairs of tubulose skirts of rib axle knob overlap the cancellation of 2 application forces, thereby the projection 220 that the tubulose skirt is overlapped on 2 distending sheets, 22 free ends withdraws from, and can take out related accessory from relief groove 3.
The above embodiment for preferred embodiment of the present invention, is not to limit practical range of the present invention with this just, and the equivalence that all shapes according to the present invention, structure and principle are done changes, and all should be covered by in protection scope of the present invention.
