Abstract
The utility model relates to a rolling door electric door opener, which adopts a gear ring with inner teeth as a speed reducing and transmission drive, the reducing and transmission drive is tightly combined with a machine casing, and the structure is compact. A power source adopts low voltage direct current and is free of electric shock hazard, an accumulator cell also can be adopted to supply power, and the worry that the rolling door can not be opened because of power off can be avoided. When being installed, an axle hole is only required to be drilled at the center of the rolling door, the destructibility to the original door body structure is small, and the installation is convenient. The rolling door is directly fixed on the gear ring, and compared with a chain driven type door opener, the utility model has small running noise. The door opener can be widely applied in the rolling doors of a garage, a warehouse, a plant and a storefront.
Description
Technical field
The utility model relates to a kind of door opener, is meant a kind of electric door-opening machine that is used for rolling door specifically.
Background technology
Existing door lifter generally is made up of casing and motor, speed reduction gearing and the self-con-tained unit fixed on it, self-con-tained unit generally comprises travel switch and clutch, this deceleration device generally is made of one group of train of reduction gears, rotating speed of motor is reduced, this structure is complicated, causes the volume of door lifter bigger.Transmission device generally adopts chain to drive the rolling door motion, and the noise during operation is big.
The utility model content
The utility model provides a kind of compact conformation, the little rolling door electric door-opening machine of operation noise.
The utility model adopts following technical scheme: this rolling door electric door-opening machine, comprise annular casing and motor, speed reduction gearing and the self-con-tained unit fixed on it, self-con-tained unit comprises travel switch and clutch, wherein, described casing is provided with cannelure along its periphery, this casing radially is divided into ring and encircles two parts down along it, and last ring and following ring are by a bolt; Described deceleration device is one to be provided with the ring gear of internal tooth, and this ring gear radially is divided into ring and ring two parts down along it, last ring and encircle down and pass through screw, and this ring gear is located in the described cannelure; The output of described motor is positioned at cannelure and mutually meshing with ring gear.
A kind of preferable casing structure is made up of 2 semicircular ring and 4 halfround bar slices that are fixedly arranged on this semicircular ring side, and the diameter of described halfround bar slice is greater than the semicircular ring diameter, and the cavity that described 4 halfround bar slices surround constitutes described cannelure.
Also be provided with spring bearing on the described casing inner wall, this spring bearing is close proximity to described ring gear inwall, and it is more steady that ring gear is rotated.
For ease of installing, described bolt is along the radial direction setting of casing.During installation, centre drill one axis hole at the rolling door axle is buckled in casing on the axis hole, and bolt passes axis hole, makes casing fixedly on the rolling door axle.
By above-mentioned description to the utility model structure as can be known, compare with prior art, the utility model adopts the ring gear that is provided with internal tooth as slowing down and transmission device, combines closely compact conformation with the structure of casing.During installation, only need centre drill one axis hole, destroy little, easy for installation former door body structure at the rolling door axle.Rolling door is directly fixed on the ring gear, drives the formula door lifter with chain and compares, and the operation noise is little.This door lifter can be widely used in the rolling door of garage, warehouse, factory building, StoreFront.

The specific embodiment
Describe the specific embodiment of the present utility model in detail below with reference to Fig. 1-4.
Casing is made up of 2 semicircular ring 3 and 4 halfround bar slices 6, and halfround bar slice 6 is fixed in semicircular ring 3 sides, and two parts are fixing by bolt 5 up and down for it.Ring gear 1 is divided into ring and ring two parts are also fixing by screw 4 down, and its gear teeth 11 are located on the inwall.Motor 2, clutch 7 and travel switch 8 are fixed on the casing, and motor 2 is selected direct current generator for use, and its output is mutually meshing with ring gear 1.Spring bearing 61 is hubbed on the halfround bar slice 6, plays to make ring gear 1 rotate effect more stably.
During installation, as shown in Figure 4, bore an axis hole 91 earlier on rolling door axle 9, this door lifter is taken apart, bolt 5 passes casing and axis hole 91, and casing is fixed on the rolling door axle 9, ring gear 1 is installed on the casing again, and motor 2 is connected power supply and is connected with control panel.Power supply adopts low-voltage DC, does not have the danger of electric shock, and also available battery power supply can be avoided the sorrow that has a power failure and cause rolling door to open.
Above-mentioned is a specific embodiment of the present utility model, but design concept of the present utility model is not limited thereto, and allly utilizes this design that the utility model is carried out the change of unsubstantiality, all belongs to the behavior of invading the utility model protection domain.
