After having adopted above -mentioned structure, through elevating gear can be fine deliver to the air outlet with amount of wind cover, do not need artifical hand to lift the operation, need not set up the platform yet, reduced manpower, time and test cost, improved efficiency of software testing, alleviateed artifical burden.
Description
Technical field
The utility model relates to a kind of air quantity shield in wind speed measurement technical field, especially relates to a kind of sealing air quantity shield with lifting.
Background technology
Air quantity shield is formed primarily of three parts: air quantity cover body, pedestal, PDA are formed.Air quantity cover body is mainly used in gathering air quantity, wind is collected to the wind speed homogenizer on basis.The workshop of pharmacy corporation is after air cleaning system high efficiency particulate air filter is installed, in order to confirm and check whether air quantity meets the requirements, usually actual air volume cover is needed to test the ventilation situation in air cleaning system certain hour, need tester's hand to lift air quantity shield when usual test and arrive air outlet, long-time operation can make tester's arm ache, when top, workshop is higher, a tester can not complete test assignment, need to set up platform and many people to operate and just can complete, like this by waste a large amount of time and manpower, add testing cost.
Summary of the invention
Technical problem to be solved in the utility model is to provide a kind of sealing air quantity shield with lifting not needing hand act can complete test.
The technical scheme in the invention for solving the technical problem is: a kind of sealing air quantity shield with lifting, comprise air quantity cover body, pedestal below air quantity cover body and be positioned at the signal transacting terminal of base interior, described base bottom is provided with jacking gear, described jacking gear comprises base, described base side is provided with directive slide track, described directive slide track is provided with guide runner, and described guide runner is fixed on base bottom; Arrange rack combination at the opposite side of described base, the bottom of described pedestal is provided with a gear, and described wheel and rack combination engagement, described gear is driven by motor.
Concrete further, described rack combination comprises the location tooth bar be fixed on base, described location tooth bar has two, in the middle part of the location tooth bar described in two, be provided with movable rack, the side of described location tooth bar and movable rack is equipped with locate square hole and fixed by square bearing pin.
Concrete further, described movable rack at least one.
Concrete further, described movable rack side arranges to connect protrudes, opposite side arranges connecting groove, adjacent described movable rack is located with connecting groove by connecting to protrude, location tooth bar described in one of them protrudes for connecting near the side of movable rack, and the location tooth bar described in another is connecting groove near the side of movable rack.
The beneficial effects of the utility model are: after have employed said structure, can be good at air quantity shield to deliver to air outlet by jacking gear, artificial hand is not needed to lift operation, do not need to set up platform yet, reduce manpower, time and testing cost, improve testing efficiency, alleviate artificial burden.
Accompanying drawing explanation
Fig. 1 is side-looking structural representation of the present utility model;
Fig. 2 is main TV structure schematic diagram of the present utility model.
In figure: 1, air quantity cover body; 2, pedestal; 3, base; 4, directive slide track; 5, guide runner; 6, gear; 7, tooth bar is located; 8, movable rack; 9, square bearing pin.
Embodiment
Below in conjunction with accompanying drawing, the utility model is explained in detail.
A kind of sealing air quantity shield with lifting as depicted in figs. 1 and 2, comprise air quantity cover body 1, pedestal 2 below air quantity cover body 1 and be positioned at the signal transacting terminal of pedestal 2 inside, jacking gear is provided with bottom described pedestal 2, described jacking gear comprises base 3, described base 3 side is provided with directive slide track 4, described directive slide track 4 is provided with guide runner 5, and described guide runner 5 is fixed on bottom pedestal 2; Arrange rack combination at the opposite side of described base 3, the bottom of described pedestal 2 is provided with a gear 6, and described gear 6 engages with rack combination, and described gear 6 is driven by motor; Described rack combination comprises fixing location tooth bar 7 on the base 3, described location tooth bar 7 has two, in the middle part of the location tooth bar 7 described in two, be provided with movable rack 8, described location tooth bar 7 with the side of movable rack 8 be equipped with locate square hole fixing by square bearing pin 9; Described movable rack 8 at least one; Described movable rack 8 side arranges to connect protrudes, opposite side arranges connecting groove, adjacent described movable rack 8 is located with connecting groove by connecting to protrude, location tooth bar 7 described in one of them protrudes for connecting near the side of movable rack 8, and the location tooth bar 7 described in another is connecting groove near the side of movable rack 8.
When using, device is on the ground, movable rack 8 is also fixed by square bearing pin 9 to assigned address with connecting groove activity by connecting to protrude, motor action, and motor driven gear 6 moves in rack combination, guide runner 5 moves on directive slide track 4, after air quantity shield is delivered to assigned address, motor stop motion, now air quantity shield is started working, structure is simple, easy to operate.
Do not need artificial hand to lift, save manpower, improve measuring accuracy and test effect, reduce testing cost and running time.
It is emphasized that: be only preferred embodiment of the present utility model above, not any pro forma restriction is done to the utility model, every above embodiment is done according to technical spirit of the present utility model any simple modification, equivalent variations and modification, all still belong in the scope of technical solutions of the utility model.
