Description
Technical field
The utility model relates to a kind of mechanical encapsulation field.
Background technology
In product design, often need to use provisional closing appliance to seal the parts that require encapsulation, guarantee that encapsulating products keeps product function and performance in transhipment and temporary transient storage process, under product when one assembling process, pull down provisional closing appliance, change the outfit into formal parts or equipment.Common closing appliance has flange connection and screw connection structure.The shortcoming of flange connection is to rely on screw to connect, and by pad adjusting play, operates more loaded down with trivial details; The shortcoming of screw connection structure is that screw thread is long, and weight is larger, and dismounting is inconvenient.
Utility model content
Technology of the present utility model is dealt with problems and is: overcome the deficiencies in the prior art, a kind of closing appliance is provided, can seal the parts that require encapsulation, have simple and easy lightweight, easy to operate feature, can simplify handling procedure, improves handling efficiency.
Technical solution of the present utility model is: a kind of closing appliance for gyro-rotor, comprises housing and blanking cover; Described housing is the cylinder that inside has stepped hole, and described stepped hole comprises unthreaded hole and tapped bore, and the diameter of unthreaded hole is less than the diameter of tapped bore; Be closed object and be positioned over unthreaded hole inside, be closed the inwall that end face of object and outer circumference surface are close to first order stepped hole; Described blanking cover is the cylinder of hollow, and one end of blanking cover is Closed End, and the other end of blanking cover is perforate end face; Described Closed End is close to the other end that is closed object; On the periphery of blanking cover, have circular protrusion, on described circular protrusion, have outside thread, the outside thread of circular protrusion coordinates with the tapped bore of enclosure interior.
The externally threaded length of described circular protrusion be less than the tapped bore of enclosure interior length 1/3.
Externally threaded external diameter and difference that the external diameter of the perforate end face of described blanking cover is less than on circular protrusion are no less than 30mm.
The utility model compared with prior art beneficial effect is: the utility model straightens footpath hollow circuit cylinder blanking cover by design, utilize the short thread of blanking cover and the long screw thread fit of housing, it is short, easy to loading and unloading that screw thread screws part size, saved loaded down with trivial details that long screw thread is connected with screw; By coordinating of short thread and long screw thread, blanking cover can be adjusted position in enclosure interior, by the precession of screw thread, can make blanking cover and be closed object close contact, does not need pad, has saved the trouble of dress pad; Blanking cover adopts hollow structure, and quality is little, operates light; The external diameter of blanking cover afterbody reserves operational space more than being less than the outside thread 30mm of circular protrusion, can load and unload with hand, does not need instrument.Whole utility model has simple and easy lightweight, and easy to operate feature can be simplified handling procedure, improves handling efficiency.
Accompanying drawing explanation
Fig. 1 structural representation of the present utility model.
The specific embodiment
As shown in Figure 1, the utility model comprises housing 1 and blanking cover 2.Housing 1 is the inner cylinder that has stepped hole, and one end of housing 1 is Closed End, other end perforate, and the axial overall length of housing 1 is 240mm, the length of stepped hole is 230mm.Stepped hole comprises unthreaded hole and tapped bore 4, and the diameter of unthreaded hole is less than the diameter of tapped bore 4, and the diameter of unthreaded hole is Φ 90mm, and tapped bore 4 has negative thread M120mm.Be closed object 3 for revolution shape, and be positioned over unthreaded hole inside.Be closed end face of object 3 and outer circumference surface and be close to the inwall of unthreaded hole.The cylinder that blanking cover 2 is hollow, one end of blanking cover 2 is Closed End, the other end of blanking cover, the afterbody 7 of blanking cover is perforate end face, the inner cavity 6 that forms of blanking cover 2; The Closed End of blanking cover 2 is close to the other end that is closed object 3; On the periphery of blanking cover 2, there is circular protrusion 5, on circular protrusion 5, there is outside thread M120mm, the outside thread of circular protrusion 5 coordinates with the tapped bore 4 of housing 1 inside, and the length of the tapped bore 4 of housing 1 inside is 100mm, and the external thread length of blanking cover 2 is less than 1/3 of housing 1 tapped bore 4 length; The external diameter of the afterbody 7 of blanking cover is less than on circular protrusion 5 externally threaded external diameter and difference is no less than 30mm.
The utility model adopts the short thread of blanking cover 2 and the long tapped bore 4 of housing 1 to coordinate, and it is short, easy to loading and unloading that screw thread screws part size, saved loaded down with trivial details that long screw thread is connected with screw; By coordinating of the short thread of blanking cover 2 and the long screw thread of housing 1, blanking cover 2 can, in housing 1 internal adjustment position, by the precession of screw thread, can make blanking cover and be closed object close contact, does not need pad, has saved the trouble of dress pad; Blanking cover 2 adopts hollow structure 6, and quality is little, operates light; Externally threaded diameter and difference that afterbody 7 external diameters of blanking cover are less than circular protrusion are no less than 30mm, reserve operational space, can load and unload with hand, do not need instrument.
The content not being described in detail in the utility model specification sheets belongs to those skilled in the art's known technology.
