Certain key effect is served, is fixed in water pump lower bearing, always be originally and prevented with double nut fastening method and return pine, very
Easily cause axle sleeve to come off, cause product quality accident.
For above-mentioned deficiency, need design and develop a kind of fastener for preventing water pump lower bearing from returning pine, can
Supply above-mentioned each shortcoming.
Utility model content
In order to solve above-mentioned problem, the utility model provides a kind of fastening for preventing water pump lower bearing from returning pine
Device.
The utility model is to be achieved through the following technical solutions:
A kind of fastener for preventing water pump lower bearing from returning pine, including lower fastener, lower fastener draw-in groove, tightly
Gu screw thread, lower fastener elastic opening pin, interface chamfering, upper fastener, upper fastener elastic opening pin and thread groove,
The lower fastener inside is machined with fastening thread by Vehicle Processing, and groove is threaded between the fastening thread, described
Lower fastener lower section is provided with interface chamfering, and the lower fastener top is provided with fastener, and described tightening is fixedly mounted with
Put top and be machined with fastener elastic opening pin, the lower fastener draw-in groove top processing sets up has lower fastener bullet
Property split pin.
Preferably, the thread groove is arranged indirectly with the fastening thread.
Preferably, the fastening thread tiltedly upper 37 degree of settings, under the upper fastener elastic opening pin and water pump
The axis hole correspondence of bearing.
Preferably, the lower fastener elastic opening pin and upper fastener elastic opening pin logical are set using upper simultaneously
Meter.
Preferably, the thread groove and the fastening thread are formed in one structure.
Compared with prior art, the beneficial effects of the utility model are:The utility model design is simple, makes reasonable,
Compact conformation, is effectively prevented sleeve nut and is being produced the phenomenon for returning pine by revolving force and frictional force, preferably solves double
Nut returns the problem of pine, uses stainless steel pin, is difficult to get rusty in water, corrosion-resistant, and dress folding is convenient, 37 degree of settings of fastening thread, energy
Preferably carry out preventing returning pine, the interface chamfering of lower section can be more convenient the installation to fastener.
