Abstract
An air inlet device comprises a base and a panel. The pane is connected with the base through a press type opening and closing mechanism which comprises a cylinder sleeve fixed on the base and clamped with a switching sleeve. A switching spring, a switching rotor, a connection rod and a reset spring are arranged in space formed by the connection of the cylinder sleeve and the switching sleeve successively. The top of the connection rod is clamped with a rotation clamping position groove of a connection seat of the bottom of the panel, and a gear capable of pushing the switching rotor to rotate is arranged at the bottom of the connection rod. The switching rotor can slide in certain stroke clamping groove in the inner wall of the switching sleeve during rotation to control the distance of the connection rod stretching out of the switching sleeve. By means of the air inlet device, closed, semi-open and full-open gears of the air inlet are achieved, the air inlet sealing problem is solved, and the use reliability of products in severe environment conditions is improved.
Description
Technical field
The present invention relates to be convenient to modifying device field cooling, that ventilate, relate in particular to a kind of air inlet device.
Background technology
Existing air inlet device generally adopts unenclosed construction, change intake by blower fan or the aperture of blade, and change shape and the mounting means of air inlet base according to the applied equipment of air inlet, the long-time use of this air inlet easily accumulates dust or having foreign matter enters obstruction air inlet.Existing improvement air inlet provides cover part, while use, can close ventilating opening, but this outer cover exists two kinds of problems, first: conventionally adopt hinged bascule to open, long-time dependability reduces; Second: opening angle is wayward, if adopt wind-force to blow open, can make air inlet windage excessive, if adopt the panel of rotational structure, the vibrations of panel in the time of air intake are larger.In addition existing air inlet device base adopts chute connecting pipe, and structural stability is poor.
Utility model content
The utility model is in order to solve prior art problem, and design one has third gear and presses control mode, realizes air port closure, half-open, three kinds of patterns of standard-sized sheet, and the high air inlet device of firmness is installed.
The technical solution of the utility model is: a kind of air inlet device, comprise base and panel, and panel is connected with base by push type open-and-close mechanism, and push type open-and-close mechanism comprises: be fixed on the Connection Block on panel, have the screens of rotation groove on Connection Block; Be fixed on the jacket casing on base, jacket casing snap-action switch sleeve; Jacket casing and switch sleeve socket joint close in the space of formation and switch spring are housed successively, switch rotor, connecting rod and back-moving spring; There is and rotates the buckle of screens groove phase clamping at the top of connecting rod, the gear that connecting rod bottom has energy pull switch rotor to rotate; Switch rotor can slip in the stroke draw-in groove at switch sleeve lining place in the time rotating, thereby control connection bar stretches out the distance of described switch sleeve.
Preferred as one, stroke draw-in groove is realized panel closure, half-open, the third gear degree of depth of standard-sized sheet.
Preferred as one, switch sleeve shell place is also socketed with screen pack.
Preferred as one, the afterbody of base is provided with card fourth, and card fourth is hangnail spring leaf.
Preferred as one, connecting rod is the plastics of polyformaldehyde material.
In sum, the beneficial effects of the utility model are:
1, air port adopts push type open-and-close mechanism to realize totally-enclosed push type control mode, realizes air port closure, and half-open, three kinds of gears of standard-sized sheet, have solved the airtight problem in air port, have been improved the reliability that product uses under harsh environment scenarios.
2, hangnail spring leaf snap in another parts flat surface realize fixation.Solve air port and hard pipeline installation question, reduce mounting process and integrity problem, reduce labour cost.
Brief description of the drawings
Fig. 1 is assembling schematic diagram of the present utility model;
Detailed description of the invention
A kind of air inlet device, comprises panel 1 and base 2, and panel 1 is connected with base 2 by push type open-and-close mechanism, and push type open-and-close mechanism comprises: be fixed on the Connection Block 10 on panel 1, have the screens of rotation groove 11 on Connection Block 10; Be fixed on the jacket casing 20 on base 2, jacket casing 20 snap-action switch sleeves 4; Jacket casing 20 engages with switch sleeve 4 in the space forming and is equipped with successively: switch spring 8, switch rotor 7, connecting rod 6 and back-moving spring 5; There is and rotates the buckle 62 of screens groove 11 phase clampings at the top of connecting rod 6, the gear 61 that connecting rod 6 bottoms have energy pull switch rotor 7 to rotate; Board connects after the connecting rod 6 of push type open-and-close mechanism face to face, as long as press the optional position of panel, just can make connecting rod 6 go deep in switch sleeve 4, and pull switch rotor 7 rotates, the mode of pressing pressure-controlled refill expansion of the slide construction of similar existing automatic ball-pen, switch rotor 7 can turn over certain angle in the time of each rotation, and slip in certain stroke draw-in groove at switch sleeve 4 inwall places, stroke draw-in groove is realized panel closure, half-open, the third gear degree of depth of standard-sized sheet, thus control connection bar 6 stretches out the distance of described switch sleeve 4.Therefore panel can be according to closure at every turn in the time pressing, and half-open, the order of standard-sized sheet changes the gap between panel and base, realizes the control of intake.Solve the airtight problem in air port, be improved the reliability that product uses under harsh environment scenarios.It should be noted that, this push type open-and-close mechanism is not the slide construction of simply diverting automatic ball-pen, first this peculation is not that those skilled in the art can expect, and the design of third gear sliding tray is also a kind of progressive, and in push type open-and-close mechanism, switch spring 8 and back-moving spring 5 have played and have further realized switch rotor 7 flexibility ratios, and both symmetries play again the effect of rock-steady structure.
In addition in embodiment, connecting rod 6 is plastics of polyformaldehyde (POM) material, and this kind of material is wear resistant spends, and more corrosion-resistant and be not vulnerable to deformation.40 places, top of switch sleeve 4 shells are also socketed with screen pack 3.The afterbody of base 2 has card fourth locating hole 21, and the card fourth of hangnail spring leaf type is installed above, if by hangnail spring leaf snap in another parts flat surface realize fixation.Solve air port and hard pipeline installation question, reduce mounting process and integrity problem, reduce labour cost.
More than show and described general principle of the present utility model, principal character and advantage of the present utility model.The technical staff of the industry should understand; the utility model is not restricted to the described embodiments; that in above-described embodiment and description, describes just illustrates principle of the present utility model; under the prerequisite that does not depart from the utility model spirit and scope, the utility model also has various changes and modifications, and these changes and improvements all fall within the scope of claimed the utility model.The claimed scope of the utility model is defined by appending claims and equivalent thereof.
