Specific embodiment
A kind of full water dispenser of concrete vacuum, as depicted in figs. 1 and 2, including shell 1 and the seal box being mounted in shell 1
2, upper cover 3 is covered on seal box 2, upper cover 3 has been uniformly distributed circumferentially multiple otic placodes 31, has been connected with spring 4 on otic placode 31,
The other end of spring 4 is fixed on shell 1.The tensile elongation of spring 4 is consistent with coefficient of elasticity, so that upper cover 3 is by uniform
Lower pressure, when seal box 2 vacuumizes, upper cover 3 is mobile to seal box 2 at atmosheric pressure and compresses.Since 3 stress of upper cover is equal
Even, upper cover 3 is uniform with the variation of 2 gap of seal box in compaction process, improves sealing effect.
Referring to figs. 2 and 3, the case mouth of seal box 2 is higher by 1 a distance of shell, and upper cover 3 is equipped with the case mouth with seal box 2
Adaptable groove 33, the roof of groove 33 correspond to the sealing ring 331 that annular is equipped at case mouth, and sealing ring 331 can be rubber
Circle improves sealing effect.
The flexible flange 21 of annular is equipped on the case mouth lateral wall of seal box 2, flange 21 can be sheet rubber, flange 21
Inclination obliquely is simultaneously arranged with case mouth wall in angle.When the lid of upper cover 3 closes at the case mouth of seal box 2, upper cover 3 pushes flange 21
So that flange 21 is bent, so that flange 21 can block completely case mouth outer wall and 33 inner wall of groove, external sky is further decreased
Gas enters the possibility of seal box 2 through gap, and the effect for playing dual-seal is cooperated with sealing ring 331.
Spring 4 and shell 1 are articulated and connected, and one end that spring 4 is connect with upper cover 3 is equipped with hook, and spring 4 passes through hook and ear
The cooperation of plate 31 is fixed, so that spring 4 is easily from removal and installation in upper cover 3.As needed, the quantity of spring 4 can be 2,3
A, 4,5 or 6 and the above quantity, take 4 herein.
Referring to figs. 2 and 3, mounting hole 11, the shaft 32 that upper cover 3 passes through insertion mounting hole 11 are equipped with vertically on shell 1
Connect with shell 1, the diameter of shaft 32 is identical as the aperture of mounting hole 11, enable shaft 32 in mounting hole 11 circumferentially
Rotation and vertically lower slider.
The limiting slot 321 of annular, the cross section semicircular in shape of limiting slot 321 are equipped with far from one end of upper cover 3 in shaft 32.
32 position of shaft between limiting slot 321 and upper cover 3 is equipped with locating slot 322 along generatrix direction, and locating slot 322 can be rectangle
Slot.The depth of locating slot 322 is gradually increased from 321 one end of limiting slot to upper cover one end.
Limited position mechanism 5 is installed on the side wall of mounting hole 11, position-limit mechanism 5 includes wearing simultaneously phase along 11 radial direction of mounting hole
The elastic component 52 of limited post 51 and connection limited post 51 and 11 side wall of mounting hole to sliding, elastic component 52 can be spring.
The diameter and limiting slot 321 of limited post 51 and the diameter of locating slot 322 are adapted, so that limited post 51 is able to snap onto limit
In position slot 321 and locating slot 322.When upper cover 3 is aligned with the case mouth of seal box 2, locating slot 322 and limited post 51 exist shaft 32
On same perpendicular, prevent it from circumferentially rotating so that limited post 51 is connected in locating slot 322, it can be with accurate judgement upper cover 3
Accuracy is closed with the lid of seal box 2.
After the lid of upper cover 3 closes on seal box 2, it is spaced a distance between the top and limited post 51 of locating slot 322, so that
When upper cover 3 compresses mobile to seal box 2 during vacuumizing, shaft 32 is moved down along mounting hole 11, avoids generating
It hinders.
With reference to Fig. 3 and Fig. 4, after vacuumizing, need to remove spring 4 from upper cover 3, so that the air pressure in seal box 2
Restore normal pressure, opens upper cover 3 to move up.In order to facilitate control pressure is adjusted, tracheae, gas can be installed in upper cover 3
Pressure regulator valve is installed on pipe, pressure regulator valve is opened after experiment, extraneous gas is entered in seal box 2, it is easy to operate.
When shaft 32, which is moved upwards up to limited post 51, to be snapped onto limiting slot 321, can not continue to move up, at this time upper cover 3
It is kept completely separate with case mouth, rotary upper cover 3 leaves case mouth position.
The application method of the full water dispenser of the concrete vacuum is as follows:
Sample is put into seal box 2, then rotary upper cover 3 is mobile to the case mouth of seal box 2, when limited post 51 is caught in
It when into limiting slot 321, can not further rotate, show that upper cover 3 is aligned with the case mouth of seal box 2 at this time, push upper cover 3 and make
It, which is covered, closes on case mouth.
Then the grab of spring 4 is fixed at the otic placode 31 of upper cover 3 respectively.Carry out vacuumize process.
As vacuum degree increases, upper cover 3 is mobile to seal box 2 under atmospheric pressure, so that upper cover 3 squeezes sealing ring 331 and becomes
Shape plays sealing function.4 proper restoration of spring at this time but still to upper cover 3 generate elastic pulling force.
After pumpdown time, opens pressure regulator valve and gas is made to enter the recovery normal pressure of seal box 2.Then spring 4 is removed
And upwards lift upper cover 3, when lift power increase suddenly when, show that limited post 51 snaps onto limiting slot 321, rotary upper cover 3 from
Unpacking mouth.
The above is only the preferred embodiment of the utility model, and the protection scope of the utility model is not limited merely to
Above-described embodiment, technical solution belonging to the idea of the present invention belong to the protection scope of the utility model.It should refer to
Out, for those skilled in the art, it is without departing from the principle of the utility model it is several improvement and
Retouching, these improvements and modifications also should be regarded as the protection scope of the utility model.
