Abstract

The invention discloses a helix pull rod type door opening machine, which can be used while various flat opened type doors are opened or closed electrically. The helix pull rod type door opening machine comprises a machine body, a machine body base box and a pull rod, wherein the machine body is composed of a motor, a speed reducer or a reduction gear, a helix rod, a helix rod screw sleeve, an adjusting rod and a screw sleeve stabilizing bearing; the components are integrated with a machine body shell; the machine body base box is similar to a power supply switch base box; the machine body is hidden inside a door column; U-shaped clamps are arranged at two ends of the pull rod; and the machine body and a door body are connected through an adjusting column on the machine body and a connecting column on the door column. When the motor in the machine body is started, the helix rod is driven to rotate through the speed reducer or the reduction gear, the helix rod screw sleeve is driven to move forwards and backwards, then the pull rod is driven so as to realize the purpose of closing a door. The machine body and the pull rod are separated and are not integrated; and the machine has the advantages of small volume, low cost and simple structure; the machine body can be hidden inside the door column, and the length of the pull rod is shortened greatly, and therefore, the machine is practical, hard to damage, attractive and the like.

Description

A kind of spiral rod-pulling type door lifter

Technical field

The present invention relates generally to the motorized open and close door, and more specifically, the present invention can be used for various vertical hinged door electric openings or closes.

Background technology

At present the electric horizontal-opening door machine of production and selling has the hydraulic pressure draw-bar formula on market, the conventional helical rod-pulling type, walk wheeled, several kinds of rocker arms etc.But more than various vertical hinged door chance exist many such as involving great expense, complex structure, infringement easily, shortcoming such as pull bar is long, and is very not attractive in appearance.

Summary of the invention

The objective of the invention is to overcome shortcoming of the prior art, provide a kind of body to separate with pull bar, is not one, and it is little to have a volume, and cost is low, and is simple in structure, can make body hide with door pillar within, and the electric door-opening machine that shortens greatly of pull bar length.

The object of the invention is achieved through following technical proposals.

Spiral rod-pulling type door lifter of the present invention is by body, and box and pull bar are formed at the bottom of the body.

Said body is by motor, reducer or reduction gearing, and screw rod, the screw rod silk braid, adjustable column, the silk braid stable bearing constitutes, one and body shell.At the bottom of the said body box similar with power switch at the bottom of box, with body hide with door pillar within.Said pull bar, two ends are provided with U type folder, body are connected with a body with joint pin on the door body through the adjustable column on the body.Electric motor starting in body through reducer or reduction gearing, drives the screw rod rotation, thereby makes the screw rod silk braid movable back and forth, drives pull bar, realizes the purpose of switch door.

Good effect of the present invention is:

1. volume is little, and cost is low, and is simple in structure;

2. can make body hide with door pillar within;

3. pull bar length shortens greatly.

The specific embodiment

Below in conjunction with accompanying drawing the present invention is further described.

This spiral rod-pulling type door lifter body is by motor 1, reducer or reduction gearing 2, and screw rod 3, screw rod silk braid 4, adjustable column 5, silk braid stable bearing 6 constitutes one and body shell 7.Shown in Figure 4 like Fig. 1 Fig. 2 Fig. 3.Said pull bar 8, two ends are provided with U type folder 9.Shown in Figure 6 like Fig. 5.

Body can be installed in the box of the supporting end, thereby hides in door pillar.Adjustable column 5 is installed on the screw rod silk braid, and its length of scalable or height, thus the body end of adjusting yoke and the distance of door-hinge, to adapt to position various and door pillar.Silk braid stable bearing 6 can be stablized screw rod silk braid 4 and adjustable column 5, keeps its horizontal motion, guarantees the smooth keying of door.

When body of the present invention was installed, its screw rod 3 was parallel to ground, also can be perpendicular to ground (few situation needs).

Pull bar 8 of the present invention and screw rod 3 adopt the length of 30cm or 50cm, can satisfy the needs of all vertical hinged doors.Shown in Figure 10 like Fig. 7 Fig. 8 Fig. 9.
