Abstract
The utility model discloses a seal detection clamp of a sealed container, which mainly comprises a locking block, a rubber ring, a push block, a mandrel, a shell, a blocking cover and a piston. Because the seal detection clamp adopts an air cylinder working principle, certain gas pressure enters from a side control hole of the shell to move the piston forwards; when the piston moves forwards, the push block is pushed to extrude the rubber ring forwards, the rubber ring expands outwards to play a seal function, then, when the seal detection clamp is used for testing, air passes through a longitudinal through hole of the locking block and is communicated with a detection counter hole of the mandrel, and a detection device can be connected with a detection counter hole by a pipeline to test. The lock block, the rubber ring and the push block can be replaced and can be selected according to different hole diameters. The seal detection clamp of the sealed container has wide application range and is suitable for a container with different openings.
Description
Technical field
The utility model relates to a kind of detection anchor clamps, particularly relates to a kind of sealing detection anchor clamps of closed container.
Background technology
For some closed containers, as: the automobile brake master cylinder pump housing, need carry out sealing detection, need the closure of openings on this closed container is inflated in container again in order to carry out sealing detection.Commonly use the opening air-tight manner and be that to adopt face seals (as shown in Figure 1) to carry out airtight, promptly use block rubber 1 ' shutoff on the opening 21 ' of container 2 '.But it is bigger to work as the hole, and the hole 101 (as shown in Figure 2) that product 10 intensity are less, this method just had no idea to block this class when the wind internal pressure was big, if can't block at the mode that this type of outlet of producing mouth adopts the plane to press, also just can't detect to it.
The utility model content
The purpose of this utility model is to provide the sealing detection anchor clamps of the wider closed container of a kind of applicable surface.
For achieving the above object, technical solution of the present utility model is:
The utility model is a kind of sealing detection anchor clamps of closed container, and it mainly is made up of latch segment, rubber ring, pushing block, axle, housing, door, piston; Described housing is to have the circular containing cavity that one one end opens wide, and offers mesopore and one in the bottom of this containing cavity and is used for the side opening that control piston moves; Described rubber ring is clamped between latch segment and the pushing block, and pushing block covers the open port of housing containing cavity; Described annular door is fixed in the open port of housing containing cavity, and the piston activity is nested with in the housing containing cavity and annular door is passed in the piston outer end and pushing block leans, and between piston circular outer wall and the housing containing cavity inwall O-ring seal is set; Described axle is arranged in the housing mesopore and passes the piston that is arranged in the housing containing cavity, the housing two ends are stretched out at the axle two ends, the inside traversing through end of one passes pushing block, rubber ring and latch segment and is fixed on the latch segment, the cascaded surface of its another outside traversing through end leans at housing mesopore ora terminalis, make axle can not move inward, and on the circumferential wall of this traversing through end, radially offer the detection counterbore, this detects counterbore and is communicated with vertical counterbore through inside traversing through end, and this vertical counterbore communicates with longitudinal hole on the latch segment.
Described latch segment is a disc element, and its middle part fixedly wears a bolt with longitudinal hole, and this bolt can be spirally connected with the inside traversing through end of axle.
After adopting such scheme, because the utility model adopts the cylinder operation principle, enter certain gaseous tension from housing control side opening and make piston forward move, it will promote pushing block and push rubber ring forward when piston forward moves, and play sealing function thereby make outside Peng of rubber ring expand; Gas when testing then communicates with detection counterbore on the axle by the longitudinal hole on the latch segment, and just can test as long as checkout equipment is connected with pipeline with the detection counterbore this moment.And the latch segment on the utility model, rubber ring, pushing block can change, and can select according to the difference of different pore diameter size, and usable range is wide, applicable to having the different openings container.
Below in conjunction with the drawings and specific embodiments the utility model is further described.

Embodiment
As shown in Figure 3, Figure 4, the utility model is a kind of sealing detection anchor clamps of closed container, and it mainly is made up of latch segment 1, rubber ring 2, pushing block 3, axle 4, housing 5, door 6, piston 7.
Described housing 5 is for having the circular containing cavity 51 that one one end opens wide, and offers mesopore 52 and one in the bottom of this containing cavity 51 and is used for the side opening 53 that control piston moves; Described rubber ring 2 is clamped between latch segment 1 and the pushing block 3, and pushing block 3 covers the open port of housing 5 containing cavities 51; Described annular door 6 is fixed in the open port of housing 5 containing cavities 51.Described piston 7 is stepped, and its large cylinder 71 activities are nested with in housing 5 containing cavities 51, and its small cylinder 72 passes annular door 6 and leans with pushing block 3, between the circular outer wall of piston 7 large cylinders 71 and housing 5 containing cavities 51 inwalls O-ring seal 8 is set.
Described latch segment 1 is a disc element, and its middle part fixedly wears a bolt 11 with longitudinal hole 12, and this bolt 11 can be spirally connected with the inside traversing through end 41 of axle 4.
Described axle 4 is arranged in housing 5 mesopores 52 and passes the piston 7 that is arranged in housing 5 containing cavities 51, housing 5 both ends of the surface are stretched out at axle 4 two ends, the inside traversing through end 41 of one passes pushing block 3, rubber ring 2 and latch segment 1 also are fixed on the latch segment 1, the cascaded surface 421 of its another outside traversing through end 42 leans at housing 5 mesopores 52 ora terminalis, make axle 4 can not move inward, and on the circumferential wall of this traversing through end 42, radially offer and detect counterbore 422, this detects counterbore 422 and is communicated with vertical counterbore 411 through inside traversing through end 41, and this vertical counterbore 411 communicates with longitudinal hole 12 on the latch segment 1.In addition, between axle 4 and piston 7, be provided with O-ring seal 9.
Principle of work of the present utility model:
Enter certain pressure from housing 5 side openings 53 and make piston 7 move forward, when piston 7 moves forward, it will promote pushing block 3 and push rubber ring 2 forward, play sealing function (as shown in Figure 5) thereby make rubber ring 2 outside Peng expand; Because the longitudinal hole 12 on the latch segment 1 communicates with detection counterbore 422 vertical counterbores 411, detection counterbore 422 on the axle 4, the gas during test can enter the inner chamber of detection receptacle by the longitudinal hole 12 on the detection counterbore 422 on the axle 4, detection counterbore 422, the latch segment 1.Just can detect as long as checkout equipment is connected with detection counterbore 422 usefulness pipelines this moment.
The above, it only is the utility model preferred embodiment, so can not limit the scope that the utility model is implemented with this, i.e. the equivalence of doing according to the utility model claim and description changes and modifies, and all should still belong in the scope that the utility model patent contains.
