Abstract

The invention discloses a window lifter which is used for a device enabling a window to be closed by lifting the window. The window lifter comprises an upper cover an a lower shell body, wherein the upper cover and the lower shell body are matched, a connecting rod and a gear are connected between a chamber between the lower shell body and the upper cover in a sleeved and inserted mode in sequence, a positioning pillar is arranged in the upper cover, a connecting sleeve is fixed on the positioning pillar, the positioning hole of the connecting sleeve and the connecting rod is matched and connected with the gear in a sleeved mode, the gear is connected above the connecting rod through the connecting sleeve in an inserted mode, a gear arm is movably connected on the connecting rod, a worm base is arranged on the chamber of the lower shell body, a fixing cover matched with the worm base is arranged on the chamber of the upper cover in an outward protruding mode, a worm is placed on the worm base and is fixed through the matching between the fixing cover and the worm base, one end of the worm protrudes out of the fixing cover, and the worm, the gear and the gear arm are meshed with one another. When the window lifter is used, the moving amplitude of the worm is small, the transmission of the worm is steady, and the service life of the window lifter is prolonged.

Description

Window regulator

Technical field

The present invention relates to a kind of door and window lifting closing device, especially a kind of window regulator.

Background technique

Along with the progress of society, door and window lifting closing device has had bigger development, and the equipment of window regulator is also had higher requirement.

Existing window regulator is of a great variety; internal structure is similar mostly; it mainly is to reach lifting between the door and window with closed by carried out folding that transmission realizes connecting rod and gear arm by the worm and gear driven gear; for example: the patent No. is 201020518512.9 window regulator; comprise the loam cake and the lower shell body that cooperatively interact; sleeve is connected with connecting rod and gear successively between the chamber of the chamber of lower shell body and loam cake; be provided with locating column in the loam cake; setting sleeve is fixedly arranged on the locating column; the socket that matches of the positioning hole of connecting sleeve and connecting rod and gear; gear is plugged on the top of connecting rod by connecting sleeve; be connected with the gear arm at connecting rod; worm and gear transmission in such technology; because to the deficiency of the fixing and protection aspect of worm screw, worm screw can take place to walk about significantly in the course of the work, causes the transmission instability; gear also very easily damages, thereby influences the working life of window regulator.

Summary of the invention

The objective of the invention is a kind of stable drive that designs for the deficiency that solves above-mentioned technology and the window regulator that improves working life.

To achieve these goals, the window regulator that the present invention is designed, comprise the loam cake and the lower shell body that cooperatively interact, in the chamber between lower shell body and loam cake successively sleeve be connected with connecting rod and gear, be provided with locating column in the loam cake, setting sleeve is fixedly arranged on the locating column, the socket that matches of the positioning hole of connecting sleeve and connecting rod and gear, gear is plugged on the top of connecting rod by connecting sleeve, be connected with the gear arm at connecting rod, chamber at lower shell body is provided with the worm screw seat, is protruding with the fixed cover that cooperatively interacts with the worm screw seat on the chamber of loam cake laterally, is placed with worm screw on the worm screw seat, this worm screw is fixed by cooperating between fixed cover and the worm screw seat, and an end stretches out fixed cover, described worm screw, gear and gear arm are meshing with each other

During use, give gear by the rotation transferring power of worm screw, the transmission of power of gear is given the gear arm, realizes unlatching and the closure of gear arm and connecting rod at last.

Better for the fixed effect of worm screw, described worm screw seat is provided with the half slot that matches with worm screw, and fixed cover and half slot fit tightly.

The designed window regulator of the present invention amplitude of walking about of worm screw in the course of the work is less, stable drive and having improved working life.

Description of drawings

Fig. 1 is embodiment 1 explosive view;

Fig. 2 is embodiment 1 sectional view;

Fig. 3 is embodiment 1 overall structure schematic representation;

Fig. 4 is the structural representation of embodiment 1 worm screw means of fixation.

Among the figure: lower shell body 1, loam cake 2, worm screw seat 3, worm screw 4, gear 5, gear arm 6, fixed cover 7, connecting sleeve 8, rivet 9, connecting rod 10, locating column 12, half slot 14, positioning hole 15.

Embodiment

The invention will be further described by reference to the accompanying drawings below by embodiment.

Embodiment 1:

As Fig. 1, Fig. 2, shown in Figure 3, the described window regulator of present embodiment, comprise the loam cake 2 and the lower shell body 1 that cooperatively interact, in the chamber between lower shell body 1 and loam cake 2 successively sleeve be connected with connecting rod 10 and gear 5, be provided with locating column 12 in the loam cake 2, connecting sleeve 8 is fixedly arranged on the locating column 12, the socket that matches of the positioning hole 15 of connecting sleeve 8 and connecting rod 10 and gear 5, gear 5 is plugged on the top of connecting rod 10 by connecting sleeve 8, gear arm 6 is movably connected on the connecting rod 10 by rivet 9, chamber at lower shell body 1 is provided with worm screw seat 3, is protruding with the fixed cover 7 that cooperatively interacts with worm screw seat 3 on the chamber of loam cake 2 laterally, is placed with worm screw 4 on the worm screw seat 3, this worm screw 4 is fixed by cooperating between fixed cover 7 and the worm screw seat 3, and an end stretches out fixed cover 7, described worm screw 4, gear 5 and gear arm 6 are meshing with each other.

As shown in Figure 4, littler better with fixed effect for the amplitude of walking about of worm screw 4, described worm screw seat 3 is provided with the half slot 14 that matches with worm screw 4, and fixed cover 7 fits tightly with half slot 14.

During use, give gear 5 by the rotation transferring power of worm screw 4, the transmission of power of gear 5 is given gear arm 6, realizes unlatching and the closure of gear arm 6 and connecting rod 10 at last.

The window regulator described in the invention amplitude of walking about of worm screw in the course of the work is less, stable drive and having improved working life.
