Detailed Description

The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.

Referring to fig. 1-21, the present invention provides a technical solution: the utility model provides a clamp, includes anchor clamps body 2, crank lever 1 and bolt pull head 6 are articulated, and bolt pull head 6 is connected with nonstandard double-thread screw 10, and nonstandard double-thread screw 10 is connected with internal diameter chuck pull rod 19, and anchor clamps body 2 is connected with the internal diameter chuck, and internal diameter chuck 15 adopts elastic metal material to make, and internal diameter chuck 15 pull rod is used for strutting internal diameter chuck 15.

Specifically, the clamp tube 2 includes a horizontal portion 20 and a vertical portion 14.

Specifically, crank lever 1 is connected with gyro wheel 12 through gyro wheel round pin axle 5, and the vertical part 14 sliding contact of gyro wheel 12 and anchor clamps body 2 still is provided with location thin slice 3 on crank lever 1, is provided with plunger seat 7 on the vertical part of anchor clamps body 2, and location thin slice 3 is pegged graft on plunger seat 7 and fixed through knob stopper post 13, and it has nut 4 still to go up threaded connection on knob stopper post 13.

Specifically, the crank lever 1 and the plug pin pull head 6 are hinged in a mode that the crank lever 1 is connected through a pull head pin shaft 8, and a positioning clamp 9 for preventing the pull head pin shaft from falling off is further arranged on the pull head pin shaft 8.

Specifically, the plug pin slider 6 and the non-standard double-thread screw 10 are connected in a manner that the non-standard double-thread screw 10 is in threaded connection with a fixing nut 11 welded in the plug pin slider 6.

Specifically, the non-standard double-threaded screw 10 and the inner diameter chuck pull rod 19 are connected in a manner that the non-standard double-threaded screw 10 is connected with the inner diameter chuck pull rod 19 through a non-standard long nut 18 and a non-standard short nut 17.

Specifically, the clamp tube body 2 and the inner diameter chuck 15 are connected in a threaded manner, and a nut 16 is further connected between the inner diameter chuck 15 and the clamp tube body 2 in a threaded manner.

Specifically, the elastic metal material used for the inner diameter clamp 15 is Q235 carbon structural steel or Q275 carbon structural steel.

The working principle is as follows: the invention discloses a hinge which is formed by a crank lever 1 and a plug pin pull head 6 through a pull head pin shaft 8, and two roller pin shafts 5 are respectively used for connecting and fixing two rollers 12 and the crank lever 1 into a whole. The plug pin puller 6, the non-standard double-thread screw 10, the non-standard long nut 18, the non-standard short nut 17 and the inner diameter chuck pull rod 19 are connected into a whole through threads, and the clamp pipe body 2 and the inner diameter chuck 15 are connected into a whole through threads. While the toggle lever 1 is flattened, the roller 12 rolls on the vertical section 14 of the clamp tube 2. When the central lines of the pull head bolt 8, the roller 12 and the non-standard double-thread screw 10 are in the same straight line, the hinge four-bar mechanism of the invention can generate dead points, and simultaneously, due to the shapes of the inner diameter chuck pull rod 19 and the inner diameter chuck 15, the inner diameter chuck pull rod 19 can prop the inner diameter chuck 15 open, the maximum outer diameter size of the outer contour of the tail end of the inner diameter chuck 15 is enlarged and exceeds the inner diameter of a through hole of a corundum mullite brick, so that the corundum mullite brick can be hooked.

The plunger seat 7 is connected with the clamp tube body 2 into a whole through a screw. And the positioning sheet 3 is also connected with the crank lever 1 into a whole through a screw. When the hinge four-bar mechanism of the invention generates dead points, the pin holes on the positioning sheets 3 are matched with the positioning pins on the knob plugs 13, so as to prevent the invention from unhooking due to mistaken collision.

The invention controls the opening and closing of the inner diameter chuck 15 by pressing and pulling the crank lever 1. The operation process is as follows: when the inner diameter chuck 15 is closed, the inner diameter chuck 15 is extended to the bottom of the corundum mullite brick through hole, the crank lever 1 is pressed to open the inner diameter chuck 15, the corundum mullite brick is hooked, and then the positioning pin of the knob plunger 13 is inserted into the pin hole on the positioning sheet 3. At the moment, the invention patent can be lifted upwards to move the corundum-mullite brick. After the corundum mullite brick is moved into the heat accumulating type burner, the pin hole of the knob plunger 13 is firstly drawn out of the pin hole on the positioning sheet 3, then the crank lever 1 is pulled outwards, the inner diameter chuck 15 disappears due to the force originally applied to the inner diameter chuck 15, and the inner diameter chuck 15 rebounds to the original shape. The invention patent can now be pulled out of the corundum-mullite brick by an upward lifting movement.

Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that changes, modifications, substitutions and alterations can be made in these embodiments without departing from the principles and spirit of the invention, the scope of which is defined in the appended claims and their equivalents.
