In the figure: the screw comprises a nut 1, a screw 2, an external thread 200, a slide bar 201, a fixture block 3, a fixture block rib 300, a fixture block through hole 301, a chute 302, a spring 4, a section bar 5, a vertical groove 500 and a transverse groove 501.

Detailed Description

The present invention will be further explained with reference to the accompanying drawings.

As shown in fig. 1 and 2, a quick T-shaped bolt, including the bolt body, the bolt body includes nut 1 and screw rod 2 of fixed connection in nut 1 upper end, the upper end of screw rod 2 has external screw thread 200, set up the screw rod sliding part on the lower extreme side of screw rod 2, the screw rod sliding part is draw runner 201, fixture block 3 is established to the cover on the screw rod 2, both ends fixed connection fixture block flange 300 about 3 upper end width direction of fixture block, the middle part of fixture block 3 has the fixture block through-hole 301 that is used for cup jointing with screw rod 2, set up the fixture block sliding part identical with screw rod sliding part shape on the fixture block through-hole 301, the fixture block sliding part is spout 302, when draw runner 201 and spout 302 sliding connection, the length direction of fixture block 3 is perpendicular with the length direction of nut 1.

The utility model discloses an in another kind of embodiment, cooperation coupling spring 4 between the lower terminal surface of fixture block 3 and the up end of nut 1, spring 4 is tensile state, makes fixture block 3 and nut 1 can be stable when using fix on the section bar.

As shown in fig. 3 and 4, the connecting structure of the quick T-shaped bolt comprises the T-shaped bolt and the section bar 5, wherein the section bar 5 is provided with an inverted T-shaped groove, the inverted T-shaped groove comprises a vertical groove 500 matched with the nut 1 in shape and a transverse groove 501 matched with the fixture block 3 in shape, and the transverse groove 501 is located at the lower end of the vertical groove 500. Nut 1 sets up in horizontal groove 501, and fixture block 3 sets up in vertical groove 500, and fixture block flange 300 and the up end butt of section bar 5.

The utility model discloses a T type bolt is when the installation, earlier puts into the transverse groove 501 of section bar 5 with nut 1, then moves fixture block 3 downwards along draw runner 201, makes fixture block 3 card go into vertical groove 500. The whole installation process is fast and smooth, and the installed T-shaped bolt cannot rotate or swing, so that the installation of parts on the external thread 200 part of the T-shaped bolt is more convenient and fast.
