Abstract

A safety self-locking bolt device is composed of self-locking bolt, vibration supporting plate, motor bottom, bolt nut and bolt key, and is characterized by that the self-locking bolt is passed through the through holes of vibration supporting plate and motor bottom, the bolt nut is cover-mounted on the external thread of self-locking bolt from top to bottom and tightened, the bolt key is screwed into central screw hole of self-locking bolt, and the 4 equi-divided bolt bodies separated from cross open slot of self-locking bolt upper portion are extended toward periphery and fastened on the internal thread of bolt nut, and the back-turning phenomenon of thread can not be produced, so that it can attain the goal of preventing bolt nut from loosening, and the safety self-locking bolt detection device can be used for rail connection of railway, connection of vibration motor and supporting plate of vibration sieve and connection of engine and base, when it is vibrated for a long time, the back-turning thread phenomenon can not be produced, the effect that the tightening torque of the lock bolt nut is not changed is realized.

Description

Safety self-locking bolt device
The technical field is as follows: a safety self-locking bolt device belongs to the technical field of threaded connection.
Secondly, background art: it is known that the connection of vibration motor and vibration sieve, rail connection in railway and connection of engine and foundation are all bolt connection, and under the action of long-term vibration force, the nut can be returned and loosened, if the loosened nut is not checked frequently, the non-safety accident can be resulted, so that it is a difficult problem in bolt connection technology.
Thirdly, the invention content: in order to solve the difficult problem in the background art, the invention aims to provide a safe self-locking bolt device, which consists of a self-locking bolt detector, a vibration supporting plate, a motor footing, a lock bolt nut and a bolt key, and comprises the following components: the device is characterized in that a self-locking bolt penetrates through holes of a vibration supporting plate and a motor bottom foot, a lock bolt nut is sleeved on an external thread of the self-locking bolt from top to bottom and is screwed, a bolt key is screwed into a central screw hole of the self-locking bolt, 4 equal parts of bolt bodies separated by a cross-shaped open slot on the upper portion of the self-locking bolt extend to the periphery and are clamped on an internal thread of the lock bolt nut, the phenomenon that threads revolve and back up is avoided, the lock bolt nut is prevented from loosening, the screwing and positioning are safe, rail connection can be achieved, a vibration motor is connected with a supporting plate of a vibration screen and an engine is connected with a foundation, when long-term vibration is received, the phenomenon that threads revolve and back up is avoided, the acting force for screwing the bolt is not changed, and the screwing.
The technical scheme adopted by the device is as follows: safe self-locking bolt device comprises self-locking bolt, vibration layer board, motor footing, lock bolt nut and bolt key, its characterized in that: a round hole sinking to a certain depth is formed in the center of the bolt end face of the self-locking bolt, internal threads are formed in the middle lower portion of the round hole, an inverted cone-shaped circular pit is formed below the center of the end face of the self-locking bolt, an annular space is formed below the inverted cone-shaped circular pit, a cross-shaped open slot is formed in the upper portion of the self-locking bolt, and the bottom of the cross-shaped open slot and the lower plane of the annular space are located on the same plane; the vibrating support plate is a support plate for supporting a vibrating motor on the vibrating screen; the bottom foot of the motor is a bottom foot plate of the vibrating motor; the lock bolt nut is a nut in a standard piece; the bolt key is a hexagon socket bolt, and the neck shank of the hexagon socket head of the hexagon socket bolt inspection is an inverted cone-shaped body; the safe self-locking bolt device comprises: the device is characterized in that a self-locking bolt penetrates through holes of a vibration supporting plate and a motor bottom foot, a lock bolt nut is sleeved on an external thread of the self-locking bolt from top to bottom and is screwed, a bolt key is screwed into a central screw hole of the self-locking bolt, so that 4 equal parts of bolt bodies separated by a cross-shaped open slot on the upper portion of the self-locking bolt extend to the periphery and are clamped on an internal thread of the lock bolt nut, and the lock bolt nut does not generate a backward and rotary thread phenomenon.
The device has the advantages that: at present, the rail connection of a railway, the connection of a vibration motor and a vibration supporting plate of a vibration sieve and the connection of an engine and a foundation are all connected by bolts, and because of the action of vibration force, a screwed nut is vibrated for a long time to generate the phenomenon of circling round and reversing threads, so that the screwed nut is loosened, and non-safety accidents are caused. The self-locking bolt is adopted to replace bolt connection in the prior art, the self-locking bolt is used for rail connection, connection of a vibration motor and a vibration supporting plate of a vibration screen and connection of an engine and a foundation, when the self-locking bolt is subjected to long-term vibration, the phenomenon of backspin thread is not generated, the acting force for screwing the bolt is not changed, and the lasting safety effect of the nut screwing torque is realized.
