Description
(1) technical field
The present invention relates to a kind of quick test connector for pressure gauge.
(2) background technology
After producing, tensimeter needs it is carried out verification.Existing pressure meter calibration device is for installing joint on table top, adopt the mode that is threaded between this joint and the tensimeter: in the time of need carrying out verification to tensimeter, tensimeter need be tightened on the joint, the sealing between troublesome poeration and joint and the tensimeter is very unreliable yet.
(3) summary of the invention
In order to overcome the above-mentioned deficiency of existing pressure meter calibration joint, the invention provides a kind of tensimeter simple installation, reliable sealing quick test connector for pressure gauge when tensimeter is carried out verification.
The technical scheme that the present invention solves its technical matters is: a kind of quick test connector for pressure gauge, comprise the pressure source Connection Block of vertical layout, and described pressure source Connection Block is provided with the through hole of vertical perforation; Can slide up and down to be provided with piston in the described through hole, seal between the inwall of described piston and through hole; Be provided with vertical stage clip between the lower end of described piston and the pressure source Connection Block; Described piston offers the air hole of vertical perforation, and the upper end of described air hole is provided with O-ring seal; Described pressure source Connection Block is with fixedly cutting ferrule outward, and is affixed between described fixedly cutting ferrule and the pressure source Connection Block; Offer two openings on the described fixedly cutting ferrule, insert clamp clip in each opening, the width of described clamp clip is greater than the thickness of described fixedly cutting ferrule sidewall; Described clamp clip is positioned at the top of described pressure source Connection Block; Described fixedly cutting ferrule also is set with up and down cover outward, and the upper end of the inwall of described up and down cover is outward-dipping inclined-plane.
Further, two openings on the described fixedly cutting ferrule are about the central shaft symmetry of described fixedly cutting ferrule; The line of centres of two openings overlaps with the diameter of described fixedly cutting ferrule; Connect by connecting stage clip between described two clamp clips.
Further, seal by O-ring seal between the inwall of described piston and through hole; Be threaded between described fixedly cutting ferrule and the described pressure source Connection Block; Be provided with crossette in the endoporus of described pressure Connection Block, the upper end of described stage clip withstands on the lower surface of described piston, and the lower end of described stage clip withstands on the described crossette.
Further, the medial surface of described two clamp clips is outwards recessed arc, the inner side mounting thread of these two clamp clips.
The same through hole and the pressure source UNICOM that is fixedly mounted on the table top and makes the pressure source Connection Block of the pressure source Connection Block of this quick test connector for pressure gauge with existing joint.When carrying out manometric verification, only need tensimeter is inserted into fixedly and get final product in the cutting ferrule, make manometric lower end withstand on the O-ring seal of piston upper end and realize tentatively sealing.Be exposed at outside the outside of following two clamp clips of original state fixedly outside the cutting ferrule, after inserting tensimeter up and down putting carried, because the upper end of the inwall of up and down cover is the outward-dipping inclined-plane in face of clamp clip, therefore can two clamp clips inwardly be pushed away by this inclined-plane up and down putting in the process of carrying, after clamp clip slips over the inclined-plane, located, thereby tensimeter is held tightly by the inwall of up and down cover.
Behind the cut-in pressure source, gases at high pressure or liquid enter from the through hole of pressure source Connection Block, and promote to move on the piston, thereby make the O-ring seal and the seal degree between the tensimeter of piston upper end more reliable, and the pressure that pressure source provides is big more, and seal degree is reliable more.
Beneficial effect of the present invention is: 1. tensimeter is installed very conveniently when carrying out verification, only needs tensimeter inserted and get final product.2. tensimeter inserts the back and feeds high-pressure air source, and the sealing between tensimeter and the joint is very reliable.
(4) description of drawings
Fig. 1 is a structural representation of the present invention.
Fig. 2 is two connection diagrams between the clamp clip.
(5) embodiment
Below in conjunction with the drawings and specific embodiments the present invention is described in further detail.
With reference to Fig. 1, Fig. 2, a kind of quick test connector for pressure gauge comprises the pressure source Connection Block 1 of vertical layout, and described pressure source Connection Block 1 is provided with the through hole 2 of vertical perforation; Can slide up and down to be provided with piston 3 in the described through hole 2, seal by O-ring seal 4 between the inwall of described piston 3 and through hole 2;
Be provided with vertical stage clip 5 between the lower end of described piston 3 and the pressure source Connection Block 1: be provided with crossette in the endoporus of described pressure Connection Block 1, the upper end of described stage clip 5 withstands on the lower surface of described piston 3, and the lower end of described stage clip 5 withstands on the described crossette.
Described piston 3 offers the air hole 6 of vertical perforation, and the upper end of described air hole 6 is provided with O-ring seal 7;
Described pressure source Connection Block 1 is outer to be with fixedly cutting ferrule 8, between described fixedly cutting ferrule 8 and the pressure source Connection Block 1 by being threaded;
Offer two openings on the described fixedly cutting ferrule 8, two openings on the described fixedly cutting ferrule are about the central shaft symmetry of described fixedly cutting ferrule 8; The line of centres of two openings overlaps with the diameter of described fixedly cutting ferrule 8; Insert clamp clip 9 in each opening, connect by connecting stage clip 10 between described two clamp clips 9.The width of described clamp clip 9 is greater than the thickness of described fixedly cutting ferrule 8 sidewalls; The medial surface of described two clamp clips 9 is outwards recessed arc, the inner side mounting thread of these two clamp clips 9.Described clamp clip 9 is positioned at the top of described pressure source Connection Block 1;
