Description

Automatic opening and closing unit for window

The utility model relates to a kind of window recloser.

Window has mobile window and rotates window with the opening/shutting mode branch, between mobile window window and the window frame roller or ball is housed, about promote window, realize opening and closing; Rotate window window and window frame by hinge or rotating shaft hinge, rotate window, realize opening and closing.Mobile window can be realized automatic open and close, but the cost height is difficult to wide popularization and application, and rotation window cost is low, generally use, but rotating window must the air distribution hook, latch is controlled opened and closed positions, is difficult to realize automatic open and close, brings inconvenience to people, when particularly meeting rain, rainwater is squeezed into indoor from the window that opens wide, trouble causes economic loss sometimes especially.

The purpose of this utility model is to provide a kind of automatic opening-closing for rotating window.

Fig. 1 is a window automatic open and close device embodiment running part sectional view;

Fig. 2 is the A-A sectional view

Fig. 3 is the control circuit schematic diagram;

Fig. 4 is the utility model user mode figure.

The utility model comprises motor (6), gear reduction, gear (16), tooth bar (4), pull bar (3), shell (5), motor (6) is fixedlyed connected with gear reduction master gear (8), gear, (16) fixedly connected with gear reduction output shaft (11), gear (16) is meshed with tooth bar (4), pull bar (3) two ends respectively with tooth bar (4), window (2) is hinged, tooth bar (4) at shell (5) but in move left and right, shell (5) is loaded on the horizontal windows framework (1), motor (6) rotates, by gear reduction gear (16) is rotated, drive tooth bar (4) move left and right, because the effect of pull bar (3), make window (2) around hinge axis, realize opening and closing.

Gear reduction can be the level Four gear reduction, comprise master gear (8), stem gear (7,9,12), driven gear (13), jackshaft (10) and output shaft (11), stem gear (7,9) sky respectively is enclosed within on the jackshaft (10), stem gear (12) sky is enclosed within on the output shaft (11), driven gear (13) fixes with output shaft (11), thereby forms gear level Four speed change.Motor (6) rotates, and master gear (8) is rotated, and by stem gear (9), stem gear (12), stem gear (7), driven gear (13) output shaft (11) is rotated successively.Motor (6) is selected DC micromotor for use, and when rotating speed was 8000T/min, the speed ratio of gear reduction can be 256:1.

Gear reduction output shaft (11) lower part is shaped on screw thread (11a), output shaft (11) can be made into two sections, the lower part and the top that are shaped on screw thread are fixed together, screw thread (11a) matches with shift fork (14), forms transmission, and shift fork (14) opening contains travel switch (xk), output shaft (11) rotates, drive shift fork (14) and move up and down, shift fork (14) is stirred travel switch (xk), window is reached and motor (6) stall when fastening.

Tooth bar can be two, i.e. tooth bar (4), tooth bar (4 '), parallel gear (16) both sides that place, be meshed with gear (16) respectively, pull bar (3) also is two, an end respectively with tooth bar (4), tooth bar (4 '), hinged, the other end is hinged with left and right sides window respectively, output shaft (11) rotates, and gear (16) is rotated, and drives two tooth bars and relatively moves, because the effect of pull bar (3) opens and closes two fan windows simultaneously.For the three-light window family, the no toothed portion lengthening of tooth bar (4 '), hinged with two pull bars respectively, like this, pull bar (3) is three, can realize that just the three-light window family opens and closes simultaneously.Upward or on the window dispose humistor (SR) at shell (5), connect, can realize meeting rain automatic close window family by correct circuit.Among Fig. 1,15 is the component part.

Control circuit comprises controllable silicon (SCR), resistance (R), diode (D), humistor (SR), travel switch (xk) and switch (k), the contact O of travel switch (xk) as shown in Figure 3 ₁, O ₂Between connect motor (6), contact D, E meet positive source a, negative pole b respectively, contact F, G connect the contact O and controllable silicon (SCR) emitter stage of switch (k) respectively, controllable silicon (SCR) colelctor electrode meets positive source a, resistance (R) and diode (D) series connection back cross-over connection are between the contact O and controllable silicon (SCR) trigger electrode of switch (k), humistor (SR) cross-over connection is in controllable silicon (SCR) trigger electrode and positive source a, and switch (k) contact A, B meet positive source a, negative pole b respectively.Such connecting circuit can be realized toggle switch (k) opening and closing windows and meet rain automatic close window family.Illustrated circuit, travel switch (xk) is in E, G position, and window is in opening.

Meet rain automatic close window family.State shown in Figure 3, switch (k) is in the C place, when rainy, drench humistor (SR), its resistance descends, and humistor (SR) flows through a small trigger current, make controllable silicon (SCR) conducting, electric current is from contact G, the O of a end through controllable silicon (SCR), travel switch (xk) ₁, motor (6), contact O ₂, E gets back to b end, motor (6) electricly just change, motor (6) stall is just cut off the electricity supply at automatic close window family, and make travel switch (xk) be allocated to D, F position automatically;

Toggle switch (k) is closed window.Illustrated circuit state, toggle switch (k) is communicated with contact A, O, and resistance (R), diode (D) are by a small electric current, trigger controllable silicon (SCR), make controllable silicon (SCR) conducting, electric current is flowed through identical when meeting rain automatic close window family, and motor (6) just changes, close window, travel switch (xk) is cut off the electricity supply to D, F position, motor (6) stall.

Toggle switch (k) is opened window.Travel switch (xk) is in D, F position, and toggle switch (k) is communicated with contact B, O, and electric current is held through contact D, O from a ₂And motor (6), contact O ₁, F, O, B be back to the b end, motor (6) reverse electricity, counter-rotating is opened window, and is made travel switch (xk) be allocated to E, G position automatically, cuts off the electricity supply motor (6) stall.

The utility model has realized rotating the automatic open close of window effectively, and switch is slow, and glass is not fragile, and switch is convenient, laborsaving, and high-order window is more demonstrated advantage. Owing to do not need the direct window opening-closing of hand, window screen cloth can be fixed on the window frame, and it is unnecessary that screen window frame just becomes. Pull bar has replaced window catch, and window catch does not need, and is provided with humistor, can realize meeting the rain automatic slowly and close window. The utility model compact conformation, low cost of manufacture.
