Description
Technical field
The utility model relates to a kind of ear mount more particularly to a kind of eyelet bolt fixed ear bases.
Background technique
Currently, the fixed ear base of eyelet bolt is directly welded in equipment after being processed using steel plate, there are some problems, tear open
When unloading eyelet bolt, bolt and eyenut can hit cylinder when rotating whereabouts centered on fixed pin under the effect of gravity, produce
Raw great sound may lead to barrel distortion because of shock if it is the cylinder of thin-walled, and secondly nut and washer may be because of
Vibration causes to loosen, and slides from opening, and equipment damage and working media is caused to leak out, serious to can cause casualties.
Utility model content
The technical problems to be solved in the utility model is in order to overcome the defects of the prior art, now to provide a kind of movable joint spiral shell
Bolt fixed ear base, the anti-loose structure of boss avoid nut and gasket because vibration causes to loosen, slide, keep away from opening
Exempt from damage caused by the shock to equipment, using block, effectively prevents the shock of eyelet bolt.
The utility model is to solve above-mentioned technical problem by following technical proposals:
A kind of eyelet bolt fixed ear base of the utility model, it is characterized in that, the eyelet bolt fixed ear base includes cylinder
Body flange, upper ear seat, lower ear base, eyelet bolt, fixed pin, eyenut and gasket, the upper ear seat are set to the lower ear
The upper surface of seat, a side of the upper ear seat and lower ear base are set to the upper surface of described shell flange, and the one of the eyelet bolt
With the lower ear base by the fixed pin connection, the other end of the eyelet bolt engages phase with the eyenut screw thread at end
Connection, the gasket are set to the centre of the eyelet bolt and eyenut.
Preferably, the upper ear seat includes first picking up the ears plate, first crossbeam and boss, the both ends of the first crossbeam and institute
It states one end that first picks up the ears plate to be connected, the boss is set to the described first other end side top for picking up the ears plate.
Preferably, described first pick up the ears plate, first crossbeam and boss setting be an integral structure.
Preferably, the lower ear base includes second side otic placode, second cross beam and block, the both ends of the second cross beam and institute
The one end for stating second side otic placode is connected, and the block is set to the side lower end of the plate of picking up the ears.
Preferably, second side otic placode, second cross beam and block setting are an integral structure.
Preferably, second side otic placode is provided with fixed pin holes, and the fixed pin is set in the fixed pin holes.
The positive effect of the utility model is:
The utility model uses the anti-loose structure of boss, avoids nut and gasket because vibration causes to loosen, from opening
It is slid at mouthful, avoids damage caused by the shock to equipment, using block, effectively prevent the shock of eyelet bolt.
Detailed description of the invention
