Description
Technical field
The utility model discloses the accessory of a kind of petrochemical industry pump, specifically refer to a kind of coupling guard being applied to petrochemical industry pump.
Background technology
Petrochemical industry pump (petrochemical industry pump) is the spcific power equipment transported for oil and inflammable, explosive, the poisonous or valuable medium of chemical field.Existing petrochemical industry pump structure generally comprises the pump housing, for the motor driving pump leaf in the pump housing to rotate and the shaft coupling for being linked by the power shaft of the output shaft of motor with pump leaf.
The structure of the existing shaft coupling being applied to petrochemical industry pump generally comprises coupling guard and is arranged at the shaft coupling unit within coupling guard.Existing coupling guard is generally all mutually butted by left cover body and right cover body, and be fixed with screw bolt and nut.This fixed structure, dismounting is required for just dismounting by instruments such as spanners, and inconvenience is safeguarded in dismounting.
It addition, shaft coupling is after a long time use, its temperature meeting height, thus causing coupling guard expanded by heating, causing that expanding occurs in bolt and loosening.
Summary of the invention
The purpose of this utility model is the shortcoming and defect in order to overcome prior art to exist, and provides a kind of dismounting easy to maintenance, and adapts to the coupling guard being applied to petrochemical industry pump of coupling guard expanded by heating.
For achieving the above object, the technical solution of the utility model is to include the first semicircle cover body and the second semicircle cover body, the first described semicircle cover body and the second semicircle cover body while being hinged fixing connection, this the first semicircle cover body and the second semicircle cover body are provided with the snap close locked for the first semicircle cover body and the second semicircle cover body relative to the opposite side of its hinged place, it is characterized in that: described snap close includes the snap close main body being fixed on the first semicircle cover body and the snap fit being fixedly installed on the second semicircle cover body, described snap close main body includes the snap close substrate being fixed on the first semicircle cover body, the front end of this snap close substrate is hinged is provided with snap close switching plate, this snap close switching plate is hinged relative to the rear interval location of its hinged place with snap close substrate is provided with snap close piece, described snap close piece includes and is positioned at its front end and is fixedly installed on the snap close piece supporting leg of front buckle shaft both sides with the front buckle shaft of described snap fit snap-fit and symmetry, every described snap close piece supporting leg all includes front support leg and rear support leg, the front end of described front support leg is fixing with front buckle shaft to be connected, the rear end of rear support leg and snap close switching plate are hinged, between this front support leg rearward end with rear support leg leading section, laminating sliding coordinates side by side in opposite directions, and jointly it is arranged with compression spring outside front support leg rearward end and rear support leg leading section, described supporting leg rear end is respectively arranged with the spacing spacing block set that coordinate mutual to the two ends compressing spring with rear support leg front end.
By this setting, the front buckle shaft of snap close piece is fastened on snap fit, realize the fixing fastening to the first semicircle cover body and the second semicircle cover body, and when the first semicircle cover body and the second semicircle cover body, because expanding with heat and contract with cold, change in volume occurs, compression spring on snap close piece supporting leg adapts to its change in volume and deformation automatically, the generation sliding making front support leg and rear support leg shifts, thus changing the length of whole snap close piece supporting leg, to adapt to the change of expanding with heat and contract with cold of the first semicircle cover body and the second semicircle cover body, such that it is able to very well solve whole coupling guard volumetric expansion and problem that the first semicircle cover body and the second semicircle cover body burst mutually.
The the second semicircle cover body being described is set further on the Mosaic face of snap close side, is provided with the strip groove of indent, being provided with and the elastic packing convex tendon of strip groove phase inserting on the Mosaic face of the first described semicircle cover body, the height of this elastic packing convex tendon is more than the degree of depth of strip groove.By this setting, elastic packing convex tendon can increase elastic buffer ability between the first semicircle cover body and the second semicircle cover body further, improves its fixing stability connected.
Below in conjunction with specification drawings and specific embodiments, this utility model is described further.
