Abstract

The utility model discloses a built-in automatic rolling curtain for an electric motor; the previous manual rolling curtain machine has inconvenient use, which is easy to damage the rolling curtain, and has an external power device for the power-driven rolling curtain machine with complicated structure, easy failure, as well as high cost; the utility model comprises a rolling curtain tube, a support device, as well as a rotary device, the left and right roller bearings of the support device are supported on the rolling curtain tube inner wall, the electric motor is built in the rolling curtain tube, because the electric motor is built in the rolling curtain tube and is connected with the rotary device through a driving force transmission shaft, once the electric motor is energized or the electric motor is switched on by remote control, the electro motor starts work, the driving force transmission shaft propels the rotary device to rotate, the whole rolling curtain is propelled, thereby controlling the involution and drawdown of the rolling curtain. Because the rolling tube inner wall is supported by the left and right roller bearings, the arrangement is quite convenient, the friction of the rolling curtain tube is decreased during rotation, and the noise is reduced, the whole device has simple and novel structure and convenient operation; the utility model is widely applied in families, hotels, as well as office sites.

Description

The built-in automatic curtain device of motor

Technical field

The utility model relates to a kind of roller blind device, the built-in automatic curtain device of particularly a kind of motor.

Background technology

Manual roller shutter machine in the past generally all is to adopt rolling and putting down of manually-operated control roller shutter, the opening and closing expense, use extremely inconvenient, if operate miss can not in time stop action, be easy to damage roller shutter, in addition, also there is a kind of electric rolling mechanomotive force device external now, complex structure, easy break-down, and for general domestic household or some hotels, hotel, such automatic curtain machine will be installed on each window, and cost is incited somebody to action height very, and the financial burden that has increased the weight of the user has virtually also limited its application and popularization.

Summary of the invention

At the problems referred to above, the utility model provides a kind of simple in structure, easy to operate motor built-in automatic curtain device.

The technical scheme that its technical problem that solves the utility model adopts is:

The built-in automatic curtain device of motor, comprise the roller shutter pipe, the bracing or strutting arrangement of forming by left pipe holder, right pipe holder, the tumbler of forming by shifting block, slide block, fixed block, be set with the dynamic bearing that rolls left of a band bearing length lid on the left pipe holder of bracing or strutting arrangement, on the right pipe holder a right rolling bearing is installed, left and right roller bearings is on the roller shutter inside pipe wall, one end of motor is sleeved on the periphery that bearing length covers by the motor installing rack, and the other end links to each other with the shifting block of tumbler by power transmission shaft.

The beneficial effects of the utility model are: link to each other with tumbler owing to ensconce in the roller shutter pipe and by power transmission shaft in the motor, in case give electrical power or remote control starter motor, motor is started working, and power transmission shaft drives tumbler and rotates, and whole roller shutter pipe is driven, thereby control rolling or putting down of roller shutter, because the roller shutter inside pipe wall is by left and right roller bearings, installs very convenient, and roller shutter pipe friction minimizing when rotating, noise reduces, and whole apparatus structure is simple, easy to operate.

Description of drawings

Below in conjunction with drawings and Examples the utility model is further specified:

Fig. 1 is a structural representation of the present utility model;

Fig. 2 is a tumbler structure enlarged drawing of the present utility model.

The specific embodiment

With reference to Fig. 1, the built-in automatic curtain device of motor, comprise roller shutter pipe 1, by left pipe holder 2, the bracing or strutting arrangement that right pipe holder 2 ' is formed, by shifting block 9, slide block 10, the tumbler that fixed block 11 is formed, be set with the dynamic bearing 4 that rolls left of a band bearing length lid 5 on the left pipe holder 2 of bracing or strutting arrangement, on the right pipe holder 2 ' a right rolling bearing 4 ' is installed, a left side, right rolling bearing 4,4 ' is supported on roller shutter pipe 1 inwall, and adopt being connected of pine with the inwall of roller shutter pipe 1, make roller shutter pipe 1 light activity up and down when rotating, reduce the rotation friction of roller shutter pipe 1, thereby reduce the rotational noise of roller shutter pipe 1, reduce simultaneously to make that to the requirement of axiality is installed whole Unit Installation is convenient; One end of motor 7 is sleeved on the periphery of bearing length lid 5 by motor installing rack 6, the other end links to each other with the shifting block 9 of tumbler by power transmission shaft 8, when the power supply of connecting motor 7 or after by 7 work of remote controller starter motor, motor 7 rotates by power transmission shaft 8 drive shifting blocks 9; And along with the rotation of motor 7, power transmission shaft 8 drives shifting block 9 and rotates, and rotates thereby drive whole tumbler; Again owing to fixed block 11 links to each other with roller shutter pipe 1 inwall tight fit by a recess 11 ', fixed block 11 drives roller shutter pipe 1 and rotates, variation or remote controller remote-control motor 7 along with the dc source polarity of supplying with motor 7, can arbitrarily change the rotation direction of motor 7, the convenient rotation direction of controlling roller shutter pipe 1 freely, thus rolling or putting down of roller shutter controlled; For the vibration that reduces to bring for whole device when motor 7 rotates, the groove of one and half garden shapes can be opened in the middle part of shifting block 9; In addition, be set with the slide block 10 that with fixed block 11 tenons cooperation link to each other because shifting block 9 other ends are placed outward, form a special crosshead shoe mechanism between the three, can realize the steady transmission of power with certain fit clearance, make whole device stability of rotation, rotational noise is low.

Claims (2)

1, the built-in automatic curtain device of motor, comprise roller shutter pipe (1), by left pipe holder (2), the bracing or strutting arrangement that right pipe holder (2 ') is formed, by shifting block (9), slide block (10), the tumbler that fixed block (11) is formed, it is characterized in that being set with on the left pipe holder (2) of bracing or strutting arrangement the dynamic bearing that rolls left (4) of a band bearing length lid (5), on the right pipe holder (2 ') a right rolling bearing (4 ') is installed, a left side, right rolling bearing (4), (4 ') is supported on roller shutter pipe (1) inwall, one end of motor (7) is sleeved on the periphery that bearing length covers (5) by motor installing rack (6), and the other end links to each other with the shifting block (9) of tumbler by power transmission shaft (8).
