Abstract
The utility model discloses a test fixture with fast packing, comprising an end cover, a compression bolt and a clamp connecting hole, wherein the end cover is connected with the compression bolt, and a boss of the end cover is used for being connected with a clamp which is clamped at the boss of the end cover and a pipe workpiece to virtually ensure the connection between the end cover and the pipe workpiece; and three sections of clamp are adopted and are connected through a bolt hole by the bolt. After the pipe workpiece is inserted into the end cover, the three sections of clamp lean against on the pipe workpiece and are screwed tightly by the bolt, so that the clamp is firmly clamped on the pipe workpiece and the boss of the end cover; a sealing ring consists of six parts, namely an inner steel ring, an inner V-shaped ring, an O-shaped ring, an outer V-shaped ring, an outer steel ring and a pressing ring, and the pressing ring is connected with the end cover through the bolt; and the pressing ring adopts the structure form of a flat washer and is embedded in the end cover, so that the pressing ring can be ensured to be compacted, and the blocking to the installation of the clamp can be avoided. The test fixture with fast packing has the advantages that the installation is convenient and the sealing effect is good.
Description
Technical field
The utility model relates to a kind of plastic pipe withstand voltage test field, is specifically related to a kind of test fixture of quick encapsulation.
Background technology
The withstand voltage plugging device pattern of tubing various kinds has different separately characteristics at present.The experimenter finds still that in the course of work there are some defectives in each anchor clamps, generally concentrate on the following aspects: the one, sealing means, existing anchor clamps generally adopt the sealing of O type circle, also have and adopt the V-type circle to seal, though also can reach the effect of sealing, but in clamping process, need very strong strength that O-ring seal is compressed, O-ring seal is pressed on the tubing reliably, when carrying out High-Voltage Experimentation, still occur the problem of leaking easily.The 2nd, compress on the Design of device of O-ring seal and have certain problem, from patent retrieval, can find, the L type structure that the trim ring of narration adopts in the patent 200520080342.5 is a kind of mode that typically compresses, but this mode in use needs to install reliably, could guarantee that O-ring seal is compacted, could guarantee that clip can be in place, and in use is easy to go wrong.The 3rd, whether easy to install in the process of clamping, existing anchor clamps generally adopt the two-piece type clip, and this clip semicircle position in clamping process must be stuck on the pipe closely, effort relatively, and be easy in clamping process, damage tubing, cause defective.
Summary of the invention
For solving the deficiencies in the prior art, the utility model provides a kind of test fixture of quick encapsulation.
Technical solution adopted in the utility model is: a kind of test fixture of quick encapsulation, form by end cap, hold-down bolt, clamp connection hole, end cap is connected with hold-down bolt, be provided with the clamp connection hole in the end cap, establish two holes on the end cap, rapid-acting coupling is installed in a hole, is connected with the high-potting pipeline, the air hole that another is equipped with pressure duct and vent valve is used to test the incipient stage exhaust; The boss of end cap is used for and clamp connection, and clip is stuck on end cap boss and the tubing, guarantees being connected of end cap and tubing conscientiously; Clip adopts three lobes, adopts bolt to connect by bolt hole.Tubing leans against three lobe clips on the tubing after inserting end cap, tightens by bolt, and clip is stuck on tubing and the end cap boss firmly; Seal ring assembly is made up of six parts, forms safe and reliable sealing.Six parts are respectively interior steel ring, interior V-type circle, O type circle, outer V-type circle, outer rim and trim ring.Trim ring is connected with end cap by bolt; Trim ring adopts the version of plain washer, and embeds end cap, can either guarantee to compress O-ring seal, can avoid hindering the installation of clip again.
The beneficial effects of the utility model are: easy for installation, and good sealing effect.
Description of drawings
Accompanying drawing 1 is a structural representation of the present utility model.
Accompanying drawing 2 is the cut-open view of test fixture of the present utility model.
Wherein: air hole, 12 bolts hole, 13 bolts of ring gasket, 2 interior V-type circles, 3O type circle, 4 outer V-type circles, 5 outer rims, 6 trim rings, 7 clips, 8 hold-down bolts, 9 clamp connection holes, 10 end caps, 11 pressure ducts and vent valve in 1.
Embodiment
The utility model is described in further detail below in conjunction with accompanying drawing.
As shown in the figure, a kind of test fixture of quick encapsulation, form by end cap 10, hold-down bolt 8, clamp connection hole 9, end cap 10 is connected with hold-down bolt 8, is provided with clamp connection hole 9 in the end cap 10, establishes two holes on the end cap 10, rapid-acting coupling is installed in a hole, be connected with the high-potting pipeline, the air hole 11 that another is equipped with pressure duct and vent valve is used to test the incipient stage exhaust.
The boss of end cap 10 is used for being connected with clip 7, and clip 7 is stuck on end cap 10 boss and the tubing, guarantees being connected of end cap 10 and tubing conscientiously; Clip 7 adopts three lobes, adopts bolt 13 to connect by bolt hole 12.Tubing leans against three lobe clips 7 on the tubing after inserting end cap 10, tightens by bolt 13, and clip 7 is stuck on tubing and end cap 10 boss firmly.
Seal ring assembly is made up of six parts, forms safe and reliable sealing, and six parts are respectively interior steel ring 1, interior V-type circle 2, O type circle 3, outer V-type circle 4, outer rim 5 and trim ring 6, and trim ring 6 is connected with end cap 10 by bolt 13; Trim ring 6 adopts the version of plain washer, and embeds end cap 10, can either guarantee to compress O-ring seal, can avoid hindering the installation of clip 7 again.
