Detailed Description

The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by a person of ordinary skill in the art without creative efforts belong to the protection scope of the present invention.

Referring to fig. 1-3, the present invention provides a technical solution: the utility model provides a firm type T type double-screw bolt, includes screw post 1 and fixes dog 2 on 1 top of screw post, and two sets of swivel nuts 201 that are vertical distribution of the bottom bilateral symmetry fixedly connected with of dog 2, and the inside of two sets of swivel nuts 201 all closes soon and is connected with the screw 3 that runs through dog 2.

Specifically, as shown in fig. 1-3, the bottom end of the screw 3 is fixedly connected with a plug pin 301 having a conical structure, the two sides of the top of the stopper 2, which are located outside the screw 3, are provided with a placing groove 203, the plug pin 301 is arranged to facilitate the fixing treatment between the tail of the screw 3 and the section bar, and the placing groove 203 is arranged to facilitate the hidden placement treatment of the head of the screw 3 after the screw 3 is screwed in.

Specifically, as shown in fig. 1-3, the bottom of dog 2 is located the outside fixedly connected with sliding sleeve 202 of screw thread post 1, the outside below that the outside of screw thread post 1 is located sliding sleeve 202 is overlapped and is equipped with rubber slide 4, the outside of screw thread post 1 is located and is equipped with buffer spring 5 between dog 2 and the rubber slide 4, and buffer spring 5 is located the inboard of sliding sleeve 202, the inside of rubber slide 4 is located the outside of screw thread post 1 and has seted up the slide opening, and slide opening and screw thread post 1 are transition fit, the chooseing for use of transition fit mode, be convenient for the fixed processing of cup jointing between rubber slide 4 and the screw thread post 1.
