Description

The louver controlling organization

Technical field

The utility model relates to the louver controlling organization, more particularly, relates to a kind of louver controlling organization that is used for its outer louver of novel double-layer vent window control.

Background technology

In the door and window of building, adopt double-decker, can completely cut off the transmission of heat, certain effect is arranged for the temperature in the holding chamber, simultaneously also can sound insulation, waterproof and dustproof.But during the broiling summer, the radiant energy of the sun can heat the air in the double window interlayer, if heated air can't be got rid of, interior temperature is raise.Keep lower room temperature, can strengthen the refrigerating capacity of air-conditioning, but this mode is stored the defective of consume electric power; Can adopt the mode of ventilation to lower the temperature in addition, but must open the window this moment, its shortcoming is to allow dust, rainwater etc. easily in the inlet chamber.

On the other hand, because the cause of traditional double window self structure, cleaning, the resisting wind press capacity of its ventilation, outer window all are restricted.Therefore, strengthen window heat insulation effect, improve sunshade and ventilation ability, solve the cleaning difficulty of outer window and how to increase draught area, improve the cross-ventilation mode and become the problem that industry is paid special attention to.Preferred mode is the form that the skin of double window is designed to louver, makes its ventilation performance better, and easilier carries out cleaning.But the On/Off of outer louver is controlled to for a new problem, therefore, must design a kind of new device, guides to the control section of louver indoor.

The utility model content

At the special construction of double-layer ventilation window, the utility model will solve the problem that is difficult at the outer louvre of indoor control, allows the user at the indoor opening angle that just can control the outer louver of vent window easily, and certain self-lock ability is arranged.

The technical scheme that its technical problem that solves the utility model adopts is: construct a kind of louver controlling organization, wherein each louver sheet is fixedlyed connected with a fixed axis, each root fixed axis is hinged with first end of a connecting rod respectively, it is characterized in that, also comprise rocking handle, first bevel gear, second bevel gear, worm screw, worm gear, power transmission shaft, spur gear, tooth bar and a plurality of bearing pin; Be provided with a chute between the end of the stage casing to the second of each root connecting rod, described bearing pin is contained on the tooth bar successively by preset space length, and stretches into respectively in the chute of a connecting rod wherein; Described spur gear is contained in first end of power transmission shaft, and meshes with described tooth bar; Described worm gear is contained in second end of power transmission shaft, and with described worm engaging, the described worm screw and second bevel gear all are contained in second rotating shaft; Described second bevel gear and the first bevel gear Vertical Meshing, described first bevel gear and rocking handle all are contained in first rotating shaft;

Cooperate by said structure, the active force that can become the pulling bearing pin in chute, to move the rotary action force transformation that is applied on the described rocking handle, thus connecting rod pulling fixed axis is rotated, reach the order of opening or closing louver.Allow the user at the indoor opening angle that just can control the outer louver of vent window easily.In addition, Worm gear mechanism wherein also can be realized laborsaving and auto-lock function.

Description of drawings

The utility model is described in further detail below in conjunction with drawings and Examples, in the accompanying drawing:

Fig. 1 is the structural representation of louver controlling organization in the novel preferred embodiment of this reality;

Fig. 2 is the schematic diagram of C when seeing the louver controlling organization from Fig. 1;

Fig. 3 is that the B of Fig. 2 is to partial view;

Fig. 4 is the A-A sectional view of Fig. 2.

The specific embodiment

A preferred embodiment of the present utility model as shown in Figure 1, Figure 2, Figure 3 and Figure 4, this louver controlling organization is made up of institutes such as rocking handle 1, first bevel gear 2, second bevel gear 3, worm screw 4, worm gear 5, power transmission shaft 6, casing 7, spur gear 8, tooth bar 9, bearing pin 10, connecting rod 11, fixed axis 12 and sunshade louver sheets 13.

Wherein, the right-hand member of first bevel gear 2, second bevel gear 3, worm screw 4, worm gear 5 and power transmission shaft 6 all is contained in the casing 7.

As can be seen from Figure 1, during installation, need on the perpendicular material of the vent window framework on glass 20 right sides, bore a hole, make power transmission shaft 6 pass perpendicular material, and lead to skin by internal layer by this hole.Top among Fig. 1 is indoor, and the bottom is outdoor.Then be that the left side is outdoor among Fig. 2, the right side is indoor.

As can be seen from Figure 2, when rocking handle 1 was shaken, first bevel gear 2 can rotate thereupon, and it rotates, and the axle with directions X is a central axis in Fig. 2.

Because

second bevel gear

3 and 2 engagements of first bevel gear, so second bevel gear 3 can rotate thereupon, it rotates, and the axle with the Y direction is the center in Fig. 2, thereby will become the rotation around the axle of Y direction around the rotational transform of the axle of directions X, has realized the vertical transmission of rotating.

Because worm screw 4 is fixed in same second rotating shaft 14 with second companion's gear 3, so can rotate simultaneously with second bevel gear 3, its rotation spool is the center with the Y direction also in Fig. 2.

As can be seen from Figure 4, because the engaging structure between worm gear 5 and the worm screw 4, so worm gear 5 can be along with worm screw 4 be rotated together, it rotates, and the axle with directions X is the center in Fig. 2, thus will around the Y direction spool rotation reverted to around directions X spool rotation.

Worm gear 5 drives fixedly connected with it power transmission shaft 6 and rotates thereupon, and power transmission shaft 6 drives the spur gear 8 that is contained in its right-hand member again and rotates thereupon, and three's rotation spool is the center with directions X all in Fig. 2.

As can be seen from Figure 3, because the engaging structure between tooth bar 9 and the spur gear 8, when spur gear 8 rotated, tooth bar 9 can move up or down thereupon, thereby had become the upper and lower of tooth bar 9 to move the rotational transform of rocking handle 1.

As can be seen from Figure 2, an end and the fixed axis 12 of connecting rod 11 are hinged, and fixed axis 12 is fixedlyed connected with louver sheet 13; Offer chute 15 at the middle part of connecting rod 11, an end of bearing pin 10 is contained on the tooth bar 9, and the other end extend in the chute 15 of connecting rod 11, and can slide in chute 15; Like this, when tooth bar 9 moved up or down, bearing pin 10 can slide in chute 15, thereby connecting rod 11 pulling fixed axis 12 are rotated, and the louver sheet 13 of fixedlying connected with fixed axis 12 is also rotated simultaneously, reached the purpose of opening or closing louver.Owing to wherein adopted worm screw 4, worm gear 5 fit structures, so also have the self-locking effect.
