Abstract
The utility model discloses a rear seal plug assembly of a core gun. The assembly is provided with an inner metal core and a rubber seal component. The rubber seal component is sheathed on the periphery of the inner metal core. The utility model is characterized in that the rubber seal component is an integral hollow cylindrical rubber seal column, the rubber seal column is tightly wrapped on the middle periphery of the inner metal core, and the outer circle of the rubber seal column is bigger than the outer circle of the lower end of the inner metal core. At least one pair of groove and rib which are mutually engaged is arranged on the combination surface of the inner metal core and the rubber seal plug. The lower end periphery of the rubber seal column forms a reverse angle shape. The utility model is suitable for being used as the rear seal plug of a core gun. The utility model having the advantages of perfect structure, convenient use, little damage possibility, firmness and durability can largely improve core taking construction efficiency and safety.
Description
Technical field
The utility model relates to a kind of accessory of drilling equipment, specifically is a kind of stifled assembly of the back sealing of getting the core rifle that is used to drill through stratum geology sample core.
Background technology
Obtain in the instrument of stratum geology sample core, have a kind of crying to get the core rifle, put it to when getting geology sample core and bore in the good boring, the rifle head is squeezed in the sidewall of boring, obtain geology sample core by gunpowder explosion.The rifle head back of getting the core rifle is provided with a shutoff, and custom is called and gets the stifled assembly of sealing behind the core rifle on the industry.The stifled assembly of sealing is made of a metal inner core and a seal, and the seal of the stifled assembly of this sealing of using is two rubber seal rings at present, and it is enclosed within the periphery of metal inner core.Because they are two annulus that width is narrower that separate, and are poorly sealed close so sealing effectiveness is bad, and be very easy to damage, easy damage because of the sealing ring influences and gets normally carrying out of core in construction, has reduced the efficient and the safety of construction.Therefore, this is needed improve.
The utility model content
The purpose of this utility model is in order to solve the problems of the technologies described above, and proposes a kind of stifled assembly of sealing behind the core rifle of getting, and this total bearing structure is a global shape, combines closely with the metal inner core, is not easy to come off and damage, firm and durable.
The purpose of this utility model is achieved through the following technical solutions: assembly is blocked up in sealing after getting the core rifle, be provided with metal inner core, rubber seal, rubber seal is enclosed within the periphery of described metal inner core, it is characterized in that: the hollow cylindrical rubber seal post that described rubber seal is as a whole, this rubber seal post closely is wrapped in the middle part periphery of metal inner core, and the periphery circle of this rubber seal post is greater than the periphery circle of metal inner core lower end.
The utility model further improves and the additional project of enforcement is:
On the bonding surface that described metal inner core and rubber seal are blocked up, be provided with the groove and the fin of at least one pair of concave-convex clutch.
The periphery edge, lower end of described rubber seal post is a chamfer shape.
It is perfect to the utlity model has structure, easy to use, not fragile, and the advantage of firm and durable can improve greatly and establish the efficient and the safety of getting the core construction.
Description of drawings
Fig. 1 is the structural representation of embodiment 2 of the present utility model;
Fig. 2 is the structural representation of embodiment 1 of the present utility model.
The specific embodiment
The utility model is done the explanation of into going up the step below in conjunction with drawings and Examples: embodiment 1: referring to accompanying drawing 2, assembly is blocked up in sealing after getting the core rifle, be provided with metal inner core 1.1, rubber seal, rubber seal is enclosed within the periphery of described metal inner core, the hollow cylindrical rubber seal post 2 that described rubber seal is as a whole, this rubber seal post closely is wrapped in the middle part periphery of metal inner core, and the periphery circle of this rubber seal post is greater than the periphery circle of metal inner core lower end.On the bonding surface that described metal inner core and rubber seal are blocked up, be provided with the groove and the fin 3 of 2 pairs of concave-convex clutch.The periphery edge, lower end of described rubber seal post is a chamfer shape.
Embodiment 1: referring to accompanying drawing 2, get the stifled assembly of sealing behind the core rifle, the upper end of described metal inner core 1 is provided with a disk 1.2, and other structure is identical with embodiment 1.
The foregoing description is very good through trial effect.
Claims (3)
1. get the stifled assembly of sealing behind the core rifle for one kind, be provided with metal inner core (1,1.1), rubber seal, rubber seal is enclosed within the periphery of described metal inner core, it is characterized in that: the hollow cylindrical rubber seal post (2) that described rubber seal is as a whole, this rubber seal post closely is wrapped in the middle part periphery of metal inner core, and the periphery circle of this rubber seal post is greater than the periphery circle of metal inner core lower end.
2. according to claim 1ly get the stifled assembly of sealing behind the core rifle, it is characterized in that: on the bonding surface that described metal inner core and rubber seal are blocked up, be provided with the groove and the fin (3) of at least one pair of concave-convex clutch.
