Abstract
The utility model relates to a locking screw of the screw of which the solder is plated on. Compared with the prior art, the utility is characterized in that the fixing effect between the double-ended bolt and the screw pole can become much better due to the solder plated on the screw thread.
Description
[technical field]
The utility model relates to a kind of screw, refers in particular to a kind of screw that can not get loose between screw and the double-screw bolt.
[background technique]
Present widely used screw all is that double-screw bolt is engaged in the screw, so that object is fixed together.But in real life, often get loose phenomenon, promptly double-screw bolt is not tight from screw engagement, and this not only makes troubles to people's life, and on highly sophisticated device if screw gets loose phenomenon, can cause unthinkable loss.
Therefore, be necessary to design a kind of new screw, to overcome above-mentioned shortcoming.
[model utility content]
The purpose of this utility model is to provide a kind of anti-loose screw.
To achieve these goals, the anti-loose screw of the utility model kind is coated with scolder on the screw thread of screw.
Compared with prior art, the utlity model has following advantage:, can make the fixed effect between double-screw bolt and the screw better owing on screw thread, be coated with scolder.
[description of drawings]
Fig. 1 is the three-dimensional exploded view of the anti-loose screw of the utility model;
Fig. 2 is the sectional view of screw shown in Figure 1;
Fig. 3 is the sectional view that is coated with the double-screw bolt of scolder shown in Figure 1;
Fig. 4 is that Fig. 1 is the sectional view that is coated with the screw of scolder.
[embodiment]
Below in conjunction with accompanying drawing the anti-loose screw of the utility model is described further.
See also illustrated in figures 1 and 2ly, the anti-loose screw 100 of the utility model comprises double-screw bolt 20 and screw 30, and wherein double-screw bolt 20 is engaged in the screw 30 fixedly to place the object (scheming not show) between double-screw bolt 20 and the screw 30.
As shown in Figure 3, get loose in screw 30 in order to prevent double-screw bolt 20, be coated with scolder 40 on the screw thread 21 of double-screw bolt 20, this scolder 40 is tin cream (also can be zinc-plated), also is provided with soldering flux (figure does not show) in the screw thread 21 of double-screw bolt 20 and scolder 40 close zones.In the time of in double-screw bolt 20 is engaged on screw 30, makes scolder 40 high-temperature fusion (high temperature can utilize friction or the heating outside between double-screw bolt 20 and the screw 30 to obtain) under the effect of soldering flux, and making double-screw bolt 20 fixing more firm with screw 30, the phenomenon that can prevent to get loose takes place.
Figure 4 shows that second embodiment of the anti-loose screw of the utility model, different with the foregoing description is: do not plate scolder on the screw thread of double-screw bolt 20, but on the screw thread 61 of screw 30, be coated with scolder 50, and this scolder 50 also can be tin cream or zinc-plated, and still is provided with soldering flux (figure does not show) in the screw thread 31 of screw 30 and scolder 50 close zones.The same with the foregoing description, in the time of in double-screw bolt 20 is engaged on screw 30, make scolder 40 high-temperature fusion (high temperature can utilize friction or the heating outside between double-screw bolt 20 and the screw 30 to obtain) under the effect of soldering flux, and making double-screw bolt 20 fixing more firm with screw 30, the phenomenon that can prevent to get loose takes place.
It is exactly the 3rd embodiment of the anti-loose screw of the utility model that above-mentioned two embodiments are combined, as shown in Figures 2 and 3, promptly on the screw thread 21,31 of double-screw bolt 20 and screw 30, be coated with scolder 40,50 respectively, and scolder 40,50 also can be tin cream or zinc-plated, and screw thread 21,31 all is provided with soldering flux (figure does not show) with the close zone of scolder 40,50 respectively.The same with above-mentioned two embodiments, in the time of in double-screw bolt 20 is engaged on screw 30, make scolder 40 high-temperature fusion (high temperature can utilize friction or the heating outside between double-screw bolt 20 and the screw 30 to obtain) under the effect of soldering flux, and making double-screw bolt 20 fixing more firm with screw 30, the phenomenon that can prevent to get loose takes place.
