Abstract

The invention discloses an anti-theft inner hexagon nut, which comprises a first cylinder, a second cylinder, a plug, a blocking block, a movable rod, a pull wire, a spring, a side groove, and a limit rod. The bottom of the first cylinder is connected to the There is a second cylinder, the first cylinder and the second cylinder are both cylindrical, the first cylinder is provided with a regular hexagonal tightening hole with an open upper end, and the second cylinder is provided with a screw thread with an open end hole, the side wall of the tightening hole is provided with several side grooves, the groove bottom of the side groove is provided with a through hole, the through hole penetrates to the outer wall of the first cylinder, and a movable rod is plugged in the through hole, A limit plate is arranged on the movable rod, and a spring is clamped between the groove bottom of the side groove and the limit plate. The present invention cooperates the plug post and the blocking block with the tightening hole, so that the nut can be tightened relatively easily when the plug post and the blocking block are not installed, and the nut is not easy to be twisted after the plug post and the blocking block are installed, and has a relatively high performance. Good anti-theft effect.

Description

【Technical field】 [0001] The invention relates to the technical field of hardware, in particular to the technical field of anti-theft inner hexagon nuts. 【Background technique】 [0002] The hexagon socket nut is a commonly used nut, which is more convenient to install, and the outside looks smoother and more beautiful. The anti-theft effect of the existing hexagon socket nut is not ideal enough, and cannot well meet the demand. 【Content of invention】 [0003] The purpose of the present invention is to solve the problems in the prior art, and propose an anti-theft inner hexagon nut, which can make the inner hexagon nut have good anti-theft performance. [0004] In order to achieve the above object, the present invention proposes an anti-theft inner hexagon nut, which includes a first cylinder, a second cylinder, a plug, a blocking block, a movable rod, a pull wire, a spring, a side groove, and a limit rod. A second cylinder is connected to the bottom of a cylinder, the fi...
