Detailed Description

The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the 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 in the present invention, all other embodiments obtained by a person skilled in the art without creative efforts all belong to the protection scope of the present invention.

Examples

Please refer to fig. 1-4, a go-no-go gauge convenient to change screw gauge head, including gauge body 1 and two screw gauge heads 2, polygon notch 3 has been seted up at the both ends of gauge body 1, thread groove 5 has been seted up to the bottom surface of polygon notch 3, the bottom surface fixedly connected with of screw gauge head 2 and the connecting rod 4 that polygon notch 3 matches, thread groove 7 has been seted up in the middle part of screw gauge head 2 and connecting rod 4 runs through, wear to be equipped with bolt 6 in the groove 7, the one end of bolt 6 extends outside connecting rod 4, and with thread groove 5 threaded connection, make when installing screw gauge head 2, insert connecting rod 4 in the polygon notch 3 on gauge body 1, pass bolt 6 through thread groove 7 in screw gauge head 2 and the connecting rod 4, rotate bolt 6, make it be connected with thread groove 5, bolt 6 restrict screw gauge head 2 and connecting rod 4 can, restrict screw gauge head 2 and connecting rod 4 through polygon notch 3 and bolt 6, can use one gauge body 1, cooperate the screw gauge head 2 of a plurality of different models, save cost, waste is reduced.

Referring to fig. 3, the polygonal slot 3 has not less than six sides and each side has the same length, so that the connecting rod 4 can be conveniently inserted into the polygonal slot 3 for easy installation.

Referring to fig. 1 and 2, the bolt 6 is a hexagon socket head cap screw, and the screw gauge head 2 is provided with a recess 8 matched with the bolt 6, so that after the bolt 6 is installed, the head of the bolt 6 is located in the recess 8 and does not protrude out of the screw gauge head 2, thereby preventing the phenomenon that the screw hole to be detected on a product is closed and too shallow, so that the bolt 6 blocks the screw gauge head 2 for detection.

Referring to fig. 4, a placing groove 10 is formed in the side wall of each edge of the polygonal notch 3, and a retaining piece 9 is fixedly connected to the inside of the placing groove 10, so that threaded holes with different specifications are detected on a product, when different thread gauge heads 2 need to be replaced for multiple times, temporary limitation is performed on the connecting rod 4 through the retaining piece 9, the mounting bolt 6 is not needed, and the practicability of the device is improved.

Referring to fig. 3 and 4, the abutting sheet 9 is made of an elastic metal material, and the abutting sheet 9 made of the elastic metal material is durable.

The working principle is as follows: when installation screw gauge head 2, insert in the polygon notch 3 on the gauge body 1 with connecting rod 4, support piece 9 and carry out certain centre gripping to connecting rod 4, pass the wearing groove 7 in screw gauge head 2 and the connecting rod 4 with bolt 6, rotate bolt 6, make it be connected with thread groove 5, the head of bolt 6 is located the groove of stepping down 8, and does not stand out screw gauge head 2, bolt 6 to screw gauge head 2 and connecting rod 4 restrict can.
