Background
Along with the progress and the innovation of the technology, the operation speed of equipment and various vehicles is faster and faster in the modern industry, the loosening of bolts and nuts caused by vibration is more and more frequent, the maintenance period of the equipment and the vehicles is correspondingly shortened, the labor intensity of maintenance personnel is increased, and greater hidden danger is brought to safety production. In order to solve the current situation, a plurality of physical locking modes exist, so that the workload is increased, the bolt and nut cannot be unlocked and reused, the bolt and nut cannot be effectively locked, the original bolt and nut thread machining process is changed, and the cost is increased.
The double nuts with the same-direction threads are locked and can be loosened in use due to vibration of equipment or parts.
The addition of flat or elastic cushions can also loosen due to vibrations of the equipment or parts.
The bolt and the nut are locked by using the cotter pin, the bolt is required to be drilled, the nut is required to be grooved, and the maximum locking effect cannot be achieved due to inaccurate positioning.
The welding is locked, dismantles and increases the degree of difficulty, influences structure intensity, influences used repeatedly.
The hexagonal head bolt and nut of each other locking and paralleling each other that the perforation iron wire is articulated need tightly decide bolt and nut distance near, and can be because of the paralleling deformation pine takes off behind equipment or the vibration of spare part.
Other 'never loose' nuts or novel thread locking changes the processing technology, increases the processing difficulty and time, and correspondingly increases the use cost.
SUMMERY OF THE UTILITY MODEL
The utility model provides a mutually exclusive anti-loosening bolt and nut as a solution aiming at the bolt and nut loosening caused by vibration when mechanical equipment and various vehicles are in operation.
The technical scheme adopted by the utility model for realizing the purpose is as follows:
a mutually exclusive anti-loosening bolt and nut. The mutually exclusive anti-loosening bolt and nut are as follows: the bolt head is provided with threads in the opposite direction to the original threads of the bolt, the diameter of the bolt is increased, and the bolt is matched with the locking nut with the increased type for use; the locking novel nut that moves of mutually exclusive formula, the nut is outer along processing out the screw thread and the model diameter that are opposite direction with the original screw thread of bolt increase, and the cooperation should increase the lock nut of model and use. The mutual exclusion type anti-loosening novel bolt is matched with a reverse locking nut and is suitable for fastening equipment or parts with threads, and after the bolt is locked, the bolt is clamped and the locking nut is screwed; the mutual exclusion type anti-loosening novel nut is matched with a reverse locking nut and is suitable for fastening through hole equipment or parts, and after the nut is locked, the nut is clamped and the locking nut is screwed; the mutual exclusion type anti-loosening bolt and the mutual exclusion type anti-loosening nut are also suitable for being mixed in two modes, and the mutual exclusion type anti-loosening novel bolt and the mutual exclusion type anti-loosening novel nut can be used simultaneously when the through hole equipment or parts are fixed.
As further improvement and optimization application, the mutually exclusive anti-loosening bolt and nut can enlarge the fastening bolt and the fastening nut cap head when applied to extreme working conditions, and a high-strength elastic cushion is added between the cap head and the locking nut or the cap head and the locking nut are locked by iron wires, so that the fastening bolt, the fastening nut and the locking nut are tightly attached, relative rotation is not generated, and mutual exclusion and anti-loosening are effectively achieved.
Drawings
FIG. 1 is a schematic diagram illustrating an application of the mutually exclusive anti-loosening bolt of the present embodiment. Fastening threaded equipment or parts by using a mutually exclusive anti-loosening bolt; a is a fastening instruction of combining a novel inner hexagon bolt with a locking nut; b is novel hexagon head bolt combines lock nut fastening signal, and the section shows that it is opposite with lock nut direction to decide bolt screw thread direction, and the bolt rotation that produces after vibrations can make lock nut and the threaded connection laminating of bolt head inseparabler, and it can make lock nut and equipment or spare part threaded connection laminating inseparabler equally to produce lock nut counter rotation after vibrations to it is locking to reach the mutual exclusion.
Fig. 2 is a schematic view illustrating an application of the mutually exclusive anti-loosening nut structure of the present embodiment. Fastening through hole equipment or parts by using a mutually exclusive anti-loosening nut; c is a fastening instruction of combining the novel inner hexagon nut with the locking nut; the section shows that the direction of the screw thread of the fastening nut is opposite to that of the locking nut, the screw thread connection of the locking nut and the fastening nut can be attached more tightly due to the rotation of the fastening nut generated after vibration, and the screw thread connection of the fastening nut and the bolt can be attached more tightly due to the reverse rotation of the locking nut generated after vibration, so that mutual exclusion and looseness prevention are achieved.
Fig. 2D is a schematic view illustrating the mutual-exclusion type anti-loosening bolt and nut of the present embodiment being used together. Use simultaneously can effectively prevent that the nut is not hard up also can effectively prevent that the bolt is not hard up.
Fig. 2E is a schematic view showing the locking between the cap head and the locking nut of the present embodiment by an iron wire. The position can also use a high-strength elastic cushion, and is also suitable for fastening between a bolt head and a locking nut. After the fastening bolt and the fastening nut are added, the fastening bolt and the fastening nut are tightly attached to the locking nut, so that relative rotation is not generated, and mutual exclusion and looseness prevention are effectively achieved.
