Detailed description of the invention

The following is specific embodiment of the utility model and combine accompanying drawing, to skill of the present utility model Art scheme is further described, but this utility model is not limited to these embodiments.

As shown in Figure 1, Figure 2, Figure 4 shows, this utility model can come real by following technical proposal Existing, a kind of hex screw, including hexagonal (hexagon)nut 100 and screw rod 200, described interior hexagonal (hexagon)nut 100 include that hexagonal uppercap body 110 and lower cap body 120, lower cap body 120 are similar to six The column structure of limit shape, its length is longer, and uppercap body 110 is similar to hexagonal cap structure, One end of described lower cap body 120 offers the mounting groove 121 of annular, it is worthy of note herein, Mounting groove 121 is to be opened on the upper surface of lower cap body 120, and downwardly extends, lower cap body The bottom surface of 120 is connected with screw rod 200 one, and described uppercap body 110 is connected to described lower cap body One end of 120 corresponding described mounting grooves 121, say, that uppercap body 110 is connected to lower cap On the upper surface of body 120, and cover mounting groove 121, six sides of described lower cap body 120 On be provided with opening 122, opening 122 can be arranged to rectangle, described opening 122 and institute State mounting groove 121 to connect, in described mounting groove 121, be provided with collision piece 123 and elastic component 124, conflict on the inwall of described mounting groove 121 in described elastic component 124 one end, the other end Conflict on the one side of described collision piece 123, namely conflict in the inner side of collision piece 123 On face, in order to apply elastic force, the another side of described collision piece 123 to described collision piece 123 Extend to described mounting groove 121 from described opening 122, the namely outside of collision piece 123 Face is stretched out at opening 122, it is worthy of note herein, and the lateral surface of collision piece 123 is not Being to be all within opening 122, its lateral surface is stepped, and a part is conflicted at mounting groove On the inwall of 121, it is to avoid collision piece 123 drops out at opening 122, it is positioned at opening 122 Together with the portions of lateral side at place is conflicted with the inner concave of die nut, thus increasing friction force, Avoid skidding；When peacetime state, collision piece 123 by the elastic force effect of elastic component 124, Its lateral surface part is at outside opening 122, when die nut to turn this hex screw Time, the hexagonal indentations of die nut is enclosed within hexagonal (hexagon)nut 100, and collision piece 123 is by inwardly Extruding, the elastic force of elastic component 124 becomes big, thus collision piece 123 is tightly squeezed in hexagon On the inwall of groove, thus produce huge frictional force, by the most stuck for hexagonal (hexagon)nut 100 In hex-shaped recess, thus avoid skidding, conveniently turn this hex screw, and be worth referring to herein Going out, elastic component 124 can be preferably spring, and collision piece 123 can be preferably rubber material Matter.

As shown in Figure 1, Figure 2, Fig. 3, as indicated at 4, on the basis of above-mentioned embodiment, institute Stating collision piece 123 outward extending another side at described opening 122 is arcwall face 125, This arcwall face 125 can be so that the hexagonal indentations of die nut be inserted in so that die nut Hexagonal indentations is when being inserted in, along with the radian of arcwall face 125, and slowly extruding collision piece 123, Make collision piece 123 can contract in mounting groove 121, so that elastic component 124 produces elastic force.

As it is shown on figure 3, on the basis of above-mentioned embodiment, described arcwall face 125 is arranged Having the netted indenture 126 for increasing frictional force, netted indenture 126 can improve arcwall face 125 Coefficient of friction, thus be greatly improved frictional force, make the anti-slip effect of hexagonal (hexagon)nut 100 more Good.

As shown in Figure 1 and Figure 2, on the basis of above-mentioned embodiment, described uppercap body 110 On be provided with screw 111, described lower cap body 120 offers screw 127, described uppercap body 110 are threadeded with described lower cap body 120 with described screw 127 by described screw 111, This connected mode is very reliable, and is easy to produce installation.

As in figure 2 it is shown, on the basis of above-mentioned embodiment, described collision piece 123 is with described The quantity of elastic component 124 is six, respectively with six described opening 122 one_to_one corresponding.

Specific embodiment described herein is only to this utility model spirit theory for example Bright.This utility model person of ordinary skill in the field can be to described specific embodiment Make various amendment or supplement or use similar mode to substitute, but without departing from this reality By novel spirit or surmount scope defined in appended claims.
