Abstract

The utility model discloses a lifting frame mechanism, which mainly comprises a frame. The frame is provided with a motor 1; the motor 1 is connected with a box body 2; the box body 2 is respectively connected with a first screw rod 3 and a second crew rod 4 by a first worm wheel 31 and a second worm wheel 41; and a nut 5 is connected with the second screw rod 41. The utility model has the advantages that: the lifting frame mechanism has two functions of manual control and remote control; when the lifting frame mechanism has the function of automatically opening a flapping cover when being installed in a TV cabinet; when the flapping cover is closed, the lifting frame mechanism has the protecting function of preventing hands from being gripped; and a two-section extending mode of a three-section sliding rail with a single motor, double worm wheels and double screw rods are adopted, the used stroke is larger, and the running stroke and the speed are improved by one time compared with a single extending mode.

Description

A kind of lifting frame mechanism

Technical field

The utility model relates to the elevator mechanism in a kind of TV cabinet and all kinds of Office furniture.

Background technique

The lowering or hoisting gear of existing furniture or other occasion generally all is the single-unit stretched if adopt screw mandrel and the nut drive mechanism, and the stroke of operation is less, and noise is big, and stroke be inconvenient to regulate, prevent the tong function.

Summary of the invention

At the shortcoming of existing lowering or hoisting gear, the utility model provides a kind of lifting frame mechanism.

To achieve these goals, the technological scheme that the utility model proposed is:

A kind of lifting frame mechanism, it mainly comprises framework, and framework is provided with motor 1, is connected with casing 2 on the motor 1, is connected with a screw mandrel 3 and No. two screw mandrels 4 by a worm gear 31 and No. two worm gears 41 respectively on the casing 2, and nut 5 is connected on No. two screw mandrels 4.

The beneficial effects of the utility model: can manual and two kinds of functions of remote control, be installed in the TV cabinet, have and open the function of renovating automatically, when renovating closure, protective function with anti-tong, adopt three-section type sliding track two joints to stretch out, the stroke of use is bigger, and stroke that is moved and speed all are doubled than single-unit stretched; Noise is low, load is high, and stroke can be regulated according to actual conditions.

Embodiment

See also its implementation process of description of drawings:

A kind of lifting frame mechanism, it mainly comprises framework, and framework is provided with motor 1, is connected with casing 2 on the motor 1, is connected with a screw mandrel 3 and No. two screw mandrels 4 by a worm gear 31 and No. two worm gears 41 respectively on the casing 2, and nut 5 is connected on No. two screw mandrels 4.When motor 1 is just changeing, meeting drives a worm gear 31 and No. two worm gears 41 rotate simultaneously, wherein a worm gear 31 is to rotate counterclockwise, because a worm gear 31 is to depend on a screw mandrel 3 to move (this moment, a screw mandrel 3 was fixed), so this moment, whole casing 2 will upwards move, therefore second of the slide rail 6 that the is attached thereto joint will rise; And meanwhile, No. two worm gears 41 are to move clockwise, close-fitting No. two screw mandrels 4 can rotate also that (this moment, a screw mandrel 3 was actionless with it, and No. two screw mandrels 4 rotate), rotation owing to No. two screw mandrels 4 can drive the rising of this nut 5 above screw mandrel, thereby will drive the 3rd joint rising of slide rail 6, second joint and the 3rd joint that will produce slide rail 6 like this rise simultaneously, and speed and stroke all are doubled.When mechanism rises to certain altitude, because the effect of spring can spur the upset of renovating connection strap, make flip structure open automatically, when rising to certain altitude, mechanism can touch position limit switch and stop motion.

Otherwise when motor reversed, worm gear all can inverted running; mechanism will descend, when drop to certain apart from the time will oppress the auto-closing of flip-open cover mechanism, in the process of closure; if run into certain resistance, can flick the absorption of magnet, play the effect of protection.

Claims

1, a kind of lifting frame mechanism, it mainly comprises framework, it is characterized in that, framework is provided with motor (1), be connected with casing (2) on the motor (1), be connected with a screw mandrel (3) and No. two screw mandrels (4) by a worm gear (31) and No. two worm gears (41) respectively on the casing (2), nut (5) is connected on No. two screw mandrels (4).
