Abstract
The utility model discloses an air tightness detection device, which consists of a rotating disc, a pressure lead screw, a pressure meter, a connection rod, a limiting column, an upper press plate A, an upper press plate B, a soleplate, a ball valve, a rubber spacing piece A, a rubber spacing piece B and a bracket, wherein the sole plate, the upper press plate A and the upper press plate B are paralleled to each other; the rubber spacing piece A and the rubber spacing piece B are respectively adhered to the opposite surfaces of the soleplate, the upper press plate A and the lower press plate B, and one end of the pressure lead screw is connected with the rotating disc, and the other end passes through the upper press plate A after being engaged with the thread of an inner screwed hole on the bracket, and diameter of the lower part of the pressure lead screw which is intersected with the upper press plate A is slightly smaller than that of the upper part, and the intersection place between the pressure lead screw and the upper press plate A is free from thread, and the lower part of the pressure lead screw is connected with a nut. The air tightness detection device can ensure that the detection of an object to be detected is performed at a completely closed state, and has simple integral structure, convenient application and low cost.
Description
Technical field
The utility model relates to a kind of pick-up unit, particularly relates to a kind of air-tightness detection device that products air tightness is detected.
Background technology
In the prior art, air-tightness detection device generally is made up of base plate, pressing plate, limited post and pressure-detecting device, need during detection nut is moved downward along limited post rotating band dynamic pressure plate, make detected device reach closed state, but because each nut can not be consistent in rotary course, cause pressing plate and the base plate can't be parallel, make object to be detected under the state that seals, to detect, influence the authenticity of testing result, and cost of manufacture is higher.
The utility model content
The utility model provides a kind of air-tightness detection device at the deficiencies in the prior art.
For realizing the above object, the technical solution adopted in the utility model is:
A kind of air-tightness detection device is made up of rotating disk, pressure screw mandrel, tensimeter, connecting link, limited post, top board A, top board B, base plate, ball valve, rubber sheet gasket A, rubber sheet gasket B and support; Wherein base plate, top board A and top board B are parallel to each other, base plate and top board B equal and opposite in direction, its opposite face is bonded with rubber sheet gasket A and rubber sheet gasket B respectively, top board B is socketed on four limited posts vertical with base plate, top board B be provided with the identical coaxial through-hole of size with the rubber sheet gasket B of its bonding, be welded with the four piece connecting links vertical with top board B around the through hole, the other end of connecting link and top board A welding are connected; One end of pressure screw mandrel is connected with rotating disk, the other end be located at internal thread hole threaded engagement on the support after, pass top board A, it intersects the diameter that reaches following position with top board A and is slightly less than top, and the intersection do not have screw thread, the bottom is connected with nut; Ball valve is communicated with through hole on the top board B hermetically by draft tube, and the draft tube internal diameter is greater than through-hole diameter.
Described support lower end is welded on base plate one side.
Described tensimeter is communicated with draft tube.
The utility model utilizes limited post to limit the motion of top board B, make it parallel with base plate all the time, utilize connecting link again, the power that top board A is obtained passes to top board B equably, guaranteed the closure of object to be detected, beneficial features such as it is simple in structure, easy to operate that integral body has, with low cost.
Description of drawings
Fig. 1 is the utility model structural drawing;
Fig. 2 is the utility model partial structurtes figure;
Embodiment:
As shown in Figure 1, a kind of air-tightness detection device is made up of rotating disk 1, pressure screw mandrel 2, tensimeter 3, connecting link 4, limited post 5, top board A6, top board B7, base plate 8, ball valve 9, rubber sheet gasket A10, rubber sheet gasket B11, support 12 and draft tube 13; During enforcement, object to be detected is placed on the rubber sheet gasket B11 that bonds with base plate 8, opening is aimed at the through hole on the rubber sheet gasket A10, rotating disk 1 is moved in the direction of the clock, pressure screw mandrel 2 moves downward along the internal thread hole on the support 12, because its diameter is greater than top board A6 hole internal diameter, then drive top board A6, connecting link 4, top board B7, rubber sheet gasket A10 is together downwards along limited post 5 vertical movements, until object to be detected is airtight fully, open ball valve 9, gases at high pressure are sent into object to be detected inside by draft tube 13, close ball valve 9, recording manometer 3 numerical value are after placement a period of time, whether change the impermeability of judging detected device by observing tensimeter numerical value, after detection is finished, open ball valve 9, rotary turnplate 1 in the counterclockwise direction, utilization is fixed on the nut of pressure screw mandrel 2 lower ends with top board A6, connecting link 4, top board B7 and rubber sheet gasket A10 take out object to be detected along limited post 5 upwards vertical movements.
The utility model can guarantee that object to be detected detects under airtight fully state, one-piece construction is simple, easy to use, with low cost.
Claims (2)
1, a kind of air-tightness detection device is made up of rotating disk, pressure screw mandrel, tensimeter, connecting link, limited post, top board A, top board B, base plate, ball valve, rubber sheet gasket A, rubber sheet gasket B and support; It is characterized in that: an end of described pressure screw mandrel is connected with rotating disk, the other end be located at internal thread hole threaded engagement on the support after, pass top board A.
2, a kind of air-tightness detection device according to claim 1 is characterized in that: described pressure screw mandrel and top board A intersect and the diameter at following position is slightly less than top, and the intersection do not have screw thread, and the bottom is connected with nut.
