Abstract
The utility model relates to a door rolling machine which needs no chain transmission mechanism and can achieve self locking. The self-locking type door rolling machine comprises a motor, transmission gears, a roller shutter and a roller shutter shaft. Power drives the transmission gears through the motor, and the transmission gears drive the roller shutter to achieve ascending and descending of a roller door through the meshing function of meshing teeth I on the transmission gears and meshing teeth II on the roller shutter. The meshing function of the meshing teeth I and the meshing teeth II has the self-locking function of clamping and locating, and due to the fact that chain transmission is not needed, dropping of the roller door caused by aging and breaking of a chain is effectively prevented.
Description
Technical field
The utility model relates to a kind of door-rolling machine, and particularly a kind of chain drive that do not need can be realized the door-rolling machine of self-locking.
Background technology
At present; electric roll-up door mechanism adopts the chain drive structure more; in long use; because not well maintenance; chain in its transmission mechanism can or transship owing to wearing and tearing and fracture; mostly in the door-rolling machine safeguard protection falling proof device is not set, rolling door can freely fall and cause accident.The utility model mainly is exactly to have designed a kind of structure, does not use chain drive, and by the motor direct-drive rolling door, control it and move up and down fully, when running into accident, can the self-locking rolling door by motor.
The utility model content
Technical problem to be solved in the utility model provides a kind of simple in structure, and reliable self-locking door-rolling machine is perfectly safe, do not need traditional chain type transmission, utilize electric-machine directly-driven, in the rolling door lifting process, realized pinning the function that rolling door falls by the auto-lock function of motor and the engagement of travelling gear and rolling door.
For solving the problems of the technologies described above, the utility model is realized as follows: a kind of self-locking door-rolling machine described in the utility model comprises motor, travelling gear, roller shutter and curtain rolling shaft; The output shaft of motor is fixedlyed connected with curtain rolling shaft, and drives its rotation; Described travelling gear is separately fixed at the two ends of curtain rolling shaft; Described roller shutter and travelling gear are for being connected with a joggle.
Described travelling gear is provided with engaging tooth one.
Described roller shutter inboard is provided with engaging tooth two, and roller shutter is meshing with each other by the engaging tooth one on engaging tooth two and the travelling gear, and when travelling gear rotated with curtain rolling shaft, roller shutter carried out lifting by engagement.
Described motor is a band-type brake self-locking motor.
Good effect of the present utility model: a kind of self-locking door-rolling machine described in the utility model is simple in structure, and institute takes up space little, effectively prevents the unexpected free-falling danger of rolling door, the reliability height, and cost is low, is suitable for extensive popularization.

The specific embodiment
As shown in Figure 1 to Figure 3, a kind of self-locking door-rolling machine described in the utility model comprises motor (1), travelling gear (3), roller shutter (2) and curtain rolling shaft (4); The output shaft of motor (1) is fixedlyed connected with curtain rolling shaft (4), and drives its rotation; Described travelling gear (3) is separately fixed at the two ends of curtain rolling shaft (4); Described roller shutter (2) and travelling gear (3) are for being connected with a joggle.
Described travelling gear (3) is provided with engaging tooth one (5).
Described roller shutter (2) inboard is provided with engaging tooth two (6), roller shutter (2) is meshing with each other by the engaging tooth one (5) on engaging tooth two (6) and the travelling gear (3), when travelling gear (3) rotates with curtain rolling shaft (4), roller shutter (2) carries out lifting by engagement, owing to be to mesh by engaging tooth, it just no longer needs chain drive, therefore there has not been the chain problem of fracture suddenly yet, because motor (1) has the band-type brake auto-lock function, as long as motor (1) does not rotate, roller shutter (2) just can lifting, effectively stops roller shutter (2) free-falling.
The course of work of the present utility model:
A kind of self-locking door-rolling machine described in the utility model, under normal operating condition, power is passed to travelling gear (3) via motor (1), by the engaging tooth one (5) above travelling gear (3) and the roller shutter (2) and the engagement of engaging tooth two (6), travelling gear (3) drives roller shutter (2) lifting; The engagement of engaging tooth one (5) and engaging tooth two (6) plays the effect of stuck location, has effectively prevented the whereabouts of rolling door.
Some principles of work and power of the relevant a kind of self-locking door-rolling machine of the utility model that just explains through diagrams recited above; owing to concerning the technician in constructed field, be easy to carry out on this basis some modifications; therefore shown in this manual is not really wanted a kind of self-locking door-rolling machine described in the utility model is confined to or in the described concrete mechanism and the scope of application; so every corresponding modify that may be utilized and equivalent, all belong to the protection domain of the utility model patent.
Claims (4)
