Abstract
The utility model discloses a rotary curtain controlling device, which is composed of a lower straining beam, a fixing frame, a rotating shaft, a locating sleeve, a spring, a end cover, a ratchet mechanism and a speed reducing mechanism. The lower straining beam is made of metal material, and the ratchet shaft and a ratchet wheel in the ratchet mechanism are made of nonmetal material. The utility model can conveniently control the lifting of a curtain. Good engaging and disengaging action can be provided, and the utility model has the advantages of reliable performance and long service life.
Description
The utility model is about the curtain control device.
In existing curtain control device, adopt spring control turning cylinder, following straining beam uses plastic material and is provided with inserted sheet, and this device is very high to the quality requirement of clutch spring, if use general spring, very fragile, performance is unreliable; The curtain control device is lighter, when wind is moved, sound is arranged; The curtain decrease speed is too fast, and window shade arrangement is damaged.
The purpose of this utility model is to overcome shortcoming of the prior art, provide that a kind of handsome in appearance, easy to use, manufacturing process is simple, the rotary curtain control device of dependable performance, long service life, it also has, and curtain steadily descends when drop-down, and the method for the bunting that is installed is easy.
The purpose of this utility model is achieved by following technical proposals:
Curtain control device of the present utility model comprises straining beam, fixed mount, rotating shaft, positioning sleeve, spring and end cap down, and ratchet mechanism one end is connected with rotating shaft, and the other end is connected with spring, and following straining beam is made up of two semi-circular members.
The utility model also can be provided with deceleration device, and deceleration device is connected with spring, and following straining beam is made by metal material, and ratchet shaft and ratchet in the ratchet mechanism are made one by nonmetallic materials.
The utility model will be further described below in conjunction with accompanying drawing and embodiment.
Fig. 1 is a structural representation of the present utility model;
Fig. 2 is the A-A cutaway view among Fig. 1.
In the drawings, an end of rotating shaft 3 is connected with fixed mount 1 by positioning sleeve 2, and other end inwall is installed ratchet mechanism, and its top is connected with fixed mount 14, and rotating shaft 3 is located axle sleeve 11 with the ratchet in positioning sleeve 2 and the ratchet mechanism and matched, and makes it to rotate simultaneously ratchet.Ratchet locating shaft 10 1 ends are processed into ratchet, preferably use nonmetallic materials.On the axle sleeve 11 of location pawl disk 12 is installed, rotatable two ratchets 13 are housed on 90 ° of angles of pawl disk, rivet 15 is fixing with pawl disk 12 with ratchet 13.During rotation since centrifugation effect ratchet 13 break away from ratchet shaft 10; When stopping operating, the ratchet engaged on ratchet 13 and the ratchet locating shaft 10 stops operating rotating shaft 3.Enclosing cover 16 is sealed ratchet mechanism.Ratchet mechanism is connected with deceleration device by spring 9, and deceleration device comprises decelerator input overcoat 4, eccentric bushing 5, gear 6, output inner gear 7, ring washer 8.When decelerator input overcoat 4 rotates a circle, be connected with spring 9 with internal gear 7 outputs by gear 6, when rotating shaft 3 rotates a circle, 9 0.6～0.7 weeks of rotation of spring.Following straining beam 18 is made up of two identical semi-circular members, as shown in Figure 2.The end of following straining beam 18 is provided with end cap 17.Following straining beam preferably uses aluminum alloy materials, and its interface is the bayonet socket of bunting.
The utility model compared with prior art has the following advantages.
1. make spring tension more reasonable. When pulling down curtain, the curtain slow decreasing uses more convenient.
2. have better clutch action, prolonged service life.
3. the bunting that is installed is easy, more reliable performance.
4. the ratchet shaft of nonmetal disjunctor and ratchet structure make manufacturing process simpler.
Claims (4)
1. rotary curtain control device, comprise fixed mount, rotating shaft, positioning sleeve, spring, end cap and following straining beam, it is characterized in that an end of ratchet mechanism is connected with described rotating shaft, the other end is connected with described spring, and described straining beam down is made up of two semi-circular members.
