Embodiment Construction

[0027] The present invention will be further described below in conjunction with accompanying drawing.

[0028] The locking mechanism of the present invention includes a set screw 1 and a structural washer 2 used in conjunction.

[0029] Such as figure 1 As shown, the set screw 1 includes a nut 11, a first screw 12, a polished rod 13 and a second screw 14 connected in sequence; the nut 11 is used for an external operation interface; the screw 12 is provided with a threaded hole with the structure to be locked The matched external thread is used to constrain the position of the set screw; the second screw rod 14 is provided with an external thread. The diameter of the polished rod 13 is smaller than the major diameter of the thread of the first screw 12 ; the major diameter of the thread of the second screw 14 is smaller than the major diameter of the thread of the first screw 12 .

[0030] Such as figure 2 As shown, the structural gasket 2 is a cylindrical structure, and a...

Abstract

The invention provides a locking mechanism in order to solve the problems that an existing locking manner may damage matched threads between threaded structures, and consequently the matched threads are possibly locked permanently, and unlocking is hard. The locking mechanism comprises a set screw and a structural gasket made from plastic or copper or aluminum. The set screw comprises a nut, a first screw rod, a polished rod and a second screw rod which are connected in sequence. The first screw rod is matched with a threaded hole in a structural body to be locked. The structural gasket is overall cylindrical an, and the lower end of the structural gasket is sealed. A threaded hole groove and a cylindrical inner cavity capable of containing the second screw rod. An internal thread of the threaded hole groove is matched with an external thread of the second screw rod. During unlocking, along with screwing out of the set screw, the structural gasket is gradually matched with the thread of the second screw rod of the set screw, so that the structural gasket is easily taken out by the set screw, taking off and replacing of the structural gasket are benefited, and it is avoided that dueto repeated locking and unlocking of the structural gasket, gasket scraps fall off, and unlocking fails.

Description

technical field [0001] The invention relates to a locking mechanism, which can be used for the locking of threaded matching structures, and can also be used for locking between two structures without matching threads, but one of the structures has a relatively sharp convex structure on the surface. lock tight. Background technique [0002] In engineering applications, thread fitting structures are often used for fixing. However, due to the influence of thermal environment and vibration environment, when only relying on thread fitting, the fitting accuracy will often decrease or even fail over time. Therefore, it is necessary to design locking for thread fitting structures. Organization to ensure its matching accuracy. [0003] At present, the locking between the first structure to be locked and the second structure to be locked through thread fit is often achieved by using set screws; The threaded hole of the to-be-locked structure body 1 and the structure body 2 to be loc...
