Abstract

A dynamic shielding device comprises a cover body, a base, a rotary ring and at least two shielding plates, wherein the cover body is provided with a through hole; the base is provided with a straight line telescopic power source; the rotary ring installed on the base can be driven to rotate by the straight line telescopic power source; and the shielding plates are capable of shielding the through hole arranged on the cover body on the lower portion. A rotary hole and a slot hole are arranged on an outer section on one side of each shielding plate; the rotary hole is sleeved on a positioning post arranged on the base; the slot hole is sleeved on a shifting lever arranged on the rotary ring; the straight line telescopic power source is arranged on the base with the same tangent direction with that of the through hole of the cover body; a straight line push rod on the top portion of the straight line telescopic power source contacts with a support arm which is arranged transversely; one end of the support arm is used for positioning; and the other end of the support arm is tightly attached to a fluctuating post on the rotary ring. The dynamic shielding device has the advantages of reasonable and compact structure, convenient and reliable use, capability of effectively shielding internal electric appliances, keeping integral feeling of the inner portion, particularly of a suspended ceiling and the like.

Description

A kind of dynamic shielding device

Technical field

The utility model relates to a kind of means for screening that is exclusively used in ceiling appliance, super bath, ventilation fan, illuminating lamp.

Background technology

Present indoor furred ceiling adopts a kind of form of structure of whole furred ceiling, he forms comparatively complete one by one furred ceiling face to the electrical part (panel) that is used on the furred ceiling with hang ceiling panel, but this and the appliance panel of hang ceiling panel basically identical are still kept away unavoidably consistent with the electrical function that install on its top, as the top installation is the infrared heating bulb, will inevitably be provided with bulb hole on the appliance panel of its below so, if what installed on top is the warm heater of ventilation fan or wind, its underpart must be equipped with the appliance panel that has the air-out grid so, if the built-in illuminating lamp of installing above, the appliance panel that has transparent member must be installed in its underpart so.Therefore no matter appliance panel designs to such an extent that how to match with hang ceiling panel, still keep away situations such as there being hole on the unavoidable electrical equipment face, can see the heating bulb of hole the inside, ventilation fan main frame by these holes, the carbon fiber heating pipe, main frame and parts such as illuminating lamp light-passing board.The bathroom heating device of Ying Yonging in early days, also be referred to as super bath, it directly is installed under the furred ceiling by in the installing hole that plucks out, in use the heating source of entire product, illuminating lamp, miscellaneous parts such as panel all are exposed to the outside, have embodied more and the inconsistent and unmatched situation of hang ceiling panel.In addition under some other user mode, electric equipment especially as illumination, air regenerating device etc., is starved of a kind of device of giving to cover under user mode not.

Summary of the invention

The purpose of this utility model is to overcome the deficiency of above-mentioned existence, and provides a kind of rational in infrastructure, compact, and is easy to use, reliable, can effectively cover when using to be exposed a dynamic shielding device that can cover up after the use.

The purpose of this utility model is finished by following technical solution, it includes a cover body that has a through hole, also include a base that the linear telescopic power source is installed, one is placed on the base and can promotes the swivel becket that rotates by described linear telescopic power source, at least two shields that maybe can cover the through hole of offering on the cover body of below, the outer section of described shield one side is provided with one is changeed hole and a slotted eye, change borehole jack and put on the reference column that is provided with on the base, and slotted eye is nested with on the driving lever that is provided with on the swivel becket.

Described linear telescopic power source places on the base identical with cover body through hole tangential direction, and its top line handspike contacts with the support arm that end location, the other end of lateral arrangement are close proximity to fluctuation post on the swivel becket.

One microswitch also radially is installed on the described base, and this microswitch is extended with a touch pole, and swivel becket is provided with projection or the projection that matches with described touch pole.

It is a kind of via the push-and-pull of linear telescopic power source that the utility model belongs to, by the connecting rod transmission, make mechanism and then certainly then reach and open automatically or auto-closing by revolution, the dynamic shielding system that can effectively cover, can keep better associative perception, it has rational in infrastructure, compact, easy to use, reliable, effectively curtain-shaped cover member or part can keep characteristics such as outside, especially furred ceiling face associative perception.

The specific embodiment

Below in conjunction with accompanying drawing the utility model is described in detail: shown in the accompanying drawing 1, the utility model includes a cover body 2 that has a through hole 1, one base 4 that linear telescopic power source 3 is installed is arranged, one is placed on the base 4 and can promotes the swivel becket 5 that rotates by described linear telescopic power source 3, at least two or (multi-disc) can be covered the shield 6 of the through hole of offering on the cover body 2 of below 1, the outer section of described shield 6 one sides is provided with one is changeed hole 7 and a slotted eye 8, change hole 7 and be nested with on the reference column 9 that is provided with on the base 4, and slotted eye 8 is nested with on the driving lever 10 that is provided with on the swivel becket 5.Shown in the figure is can cover through hole 1 on the cover body 2 fully with two shields 6.

Linear telescopic power source 3 described in the utility model places on the base 4 identical with cover body through hole 1 tangential direction, and the top line handspike of linear telescopic power source 3 is close proximity to the support arm 12 of stirring post 11 on the swivel becket 5 and contacts with an end of lateral arrangement location, the other end.

One microswitch 13 also radially is installed on the described base 4, and this microswitch 13 is extended with a touch pole 14, and swivel becket 5 is provided with projection 15 or the projection that matches with described touch pole 14.

During use, behind flexible power source 3 connection power supplys, the protruding at a slow speed stroke L in its top, support arm 12 is pushed at the top to, drives two (sheet) shields 6 of swivel becket 5 linkages by support arm again and revolves round the sun around the center together, and make each shield produce rotation by driving lever 10, when reaching required stroke, open microswitch 13 contacts again, the power supply of connecting functions such as heating or ventilation makes its operate as normal, at this moment two shields are in separated position, see shown in the accompanying drawing 2.

Behind powered-down, flexible power source can be automatically at a slow speed to the recovery L stroke that contracts, two shields of linkage return back to original hidden position, see shown in the accompanying drawing 3, and disconnect the microswitch contact, stop to warm oneself or the work of function such as ventilation.
