Description
Technical field
The utility model relates to a kind of anti-loose structure that is applied to the threaded connector on the curved surface, especially is installed in the anti-loose structure of the lip-deep threaded fastener of cylindrical component, specifically a kind of anti-loose structure that is applied to the threaded fastener on the curved surface part.
Background technique
At the curvecd surface type part, be a kind of common mechanical structure as on the surface of cylindric part threaded fastener being installed, it is of many uses.Because attachment face is not the plane, in order to guarantee to connect reliably, must adopt special anti-loose method, especially be under the vibration working environment at the curvecd surface type part, guarantee that the reliability of its connection is even more important.The anti-loose method of the threaded fastener on the existing curvecd surface type part mainly contains rubbing manipulation and destroys the method for screw pair, it is locking that rubbing manipulation utilizes spring washer to carry out exactly, and the method for destroying screw pair is that the method for coated with metal adhesive glue between the screw on screw rod and the curved surface realizes locking.The anti-loosing effect of rubbing manipulation is not good, particularly under the vibration situation, thread connector is easy to come off from the surface of curvecd surface type part, though the method that needs to destroy screw pair connects reliable, in case but the workpiece of threaded fastener is when needing to change after damaging, then must change together with the curvecd surface type part, when if a plurality of threaded fastener is installed on the same curvecd surface type part, as long as there is a threaded fastener to damage, the necessary integral replacing of then whole curvecd surface type part, not only increased cost, and very difficult sometimes.
Summary of the invention
The purpose of this utility model provide a kind of locking reliable, change the anti-loose structure that is applied to the threaded fastener on the curved surface part easily.
The technical solution of the utility model is:
A kind of anti-loose structure that is applied to the threaded fastener on the curved surface part comprises screw rod 5, nut 4, pad 2, and nut 4 spinnings are on screw rod 5, and an end of screw rod 5 and the screw 6 on the curved surface part 1 are spirally connected, and it is characterized in that nut 4 and screw rod 5 are fixed to be one; Anti-loosing slice 3 and pad 2 are installed on the screw rod 5 between nut 4 and the curved surface part 1 successively, and the profile of pad 2 is a polygonal, and its upper surface 7 contacts with anti-loosing slice 3, and its lower surface 8 matches with the surface of curved surface part 1 and contacts; Anti-loosing slice 3 is whole at least be connected with that the side of following curved locking pawl 9 that a side with pad 2 offsets and and nut 4 offsets on bend locking pawl 10.
The utility model has also been taked following technical measures:
The profile of pad 2 can be square.
Curved surface part 1 can be the cylindrical shape part.
Nut 4 and screw rod 5 can fix as one by the affixed glue of filling metal between the connection screw thread, also can fix as one by the solder joint that spot welding method produces.
The beneficial effects of the utility model:
1, connects reliably, even also can not produce loosening in the use of vibration occasion.
2, change conveniently, help reducing maintenance cost, can realize man-to-man replacing, when the mounted on surface of same curved surface part has a plurality of spiral marking connection of the present utility model, if a damage is wherein arranged, then only need change this connecting piece and get final product, and need not have a threaded fastener damage just to need to change whole curved surface part, thereby can reduce maintenance cost greatly as of the prior art.
3, utilization scope is wide, can apply on the various curved surfaces.
4, simple in structure, manufacturing, easy for installation.

Embodiment
Below in conjunction with drawings and Examples the utility model is further described.
Shown in Fig. 1～4.
A kind of anti-loose structure that is applied to the threaded fastener on the curved surface part, comprise cylindrical component 1, screw rod 5, nut 4 (can be hexagon nut), pad 2, the barrel surface of cylindrical component 1 is provided with and connects screw 6, nut 4 spinnings are fixing as one on the screw rod 5 and by the method that is connecting the affixed glue of filling metal between the screw thread, an end of screw rod 5 and the connection screw 6 on the cylindrical component 1 be spirally connected (passing through spiral marking connection); Anti-loosing slice 3 and pad 2 are installed on the screw rod 5 between nut 4 and the cylindrical component 1 successively, and the profile of pad 2 is a square, and its upper surface 7 contacts with anti-loosing slice 3, and its lower surface 8 matches with the barrel surface of cylindrical component 1 and contacts; Anti-loosing slice 3 integral body are connected with going up that the side of following curved locking pawl 9 that a side with pad 2 offsets and two and nut 4 offsets and bend locking pawl 10.
During concrete enforcement, nut 4 also can fix as one by the method for spot welding with screw rod 5.
Installation of the present utility model and replacing process are:
At first an end of screw rod 5 is screwed in the connection screw 6 on the barrel surface of cylindrical component 1, be that the square washer 2 of cylndrical surface passes screw rod 5 its cylinder bottom surface is pressed on the barrel surface of cylindrical component 1 again with the bottom surface, put anti-loosing slice 3 then, again nut 4 is screwed on and screws put in place after, to the direction bending of pad 2 side of itself and pad 2 is fitted the following curved locking pawl 9 on the anti-loosing slice 3 with instrument, make curved locking pawl 10 side of itself and nut be fitted simultaneously to the direction bending of nut 4, the special-purpose metal adhesive glue (nut 4 also can link to each other by the method for spot welding with screw rod 5) of in the screw pair between nut 4 and the screw rod 5, annotating at last, making nut and screw rod fixed is one, screws out from nut to prevent screw rod.So far, the whole erection process finishes.
When the threaded fastener damage needs to change, as long as tool using will descend to bend locking pawl 9 and peel off pad 2 sides, the side that last curved locking pawl 10 is peeled off nut 4, rotating screw bolt 5 can take off together with nut 4, pad 2, anti-loosing slice 3 it from the cylinder of cylindrical component 1, by above-mentioned Connection Step a new threaded fastener is installed again and is got final product.
The locking functions of the present utility model at first bottom surface that matches with curved surface (cylndrical surface) by pad 2 is pressed on the curved surface (cylndrical surface) and makes it to produce relative movement, secondly fit by the plane shape side of the following curved locking pawl on the anti-loosing slice 39 with pad 2, fit by the side plane of going up curved locking pawl 10 and nut 4 on the anti-loosing slice 3 simultaneously, nut 4 and pad 2 down curved locking pawl 9 and on can not do relative movement under the acting in conjunction of curved locking pawl 10, thereby make nut 4, pad 2, anti-loosing slice 3 all can not be done relative movement along the curved surface (cylndrical surface) of curved surface part 1 (cylindrical component), method by binder or welding can not relatively rotate after making nut 4 and screw rod 5 affixed again, thereby even has realized the locking connection that also can not become flexible under vibration condition.
