Description

Curtain curtain deceleration structure

The invention provides a speed reducing device, in particular to a curtain curtain deceleration structure.

Press, common curtains include general single and double curtains, roller blinds or blinds, etc., and the top of the roller blind is attached to the rotating shaft of a reel, which is driven by the reel to drive the rotating shaft and the roller blind. A return spring is arranged on the reel for conveniently winding the curtain curtain directly to the top; however, in the actual use of the roller blind, there is no buffer structure on the reel. As a result, the roller blind will generate a strong momentary retracting force when it is retracted, which not only causes the curtain to be damaged due to excessive impact, but also causes the operator to have the doubt of injury and is not practical.

In order to improve the above-mentioned use, the manufacturer has developed a damper. Please refer to the figures 10 to 13, which include: a curtain damper, which is mainly provided with a accommodating seat 51 for the damper 50. A receptacle 511 is formed in the receptacle 51, and a transposition 52 is disposed in the chamber 511. The outer edge of the transpose 52 is convexly provided with a plurality of convex ribs 521, and between the convex ribs 521 An oil-receiving portion 522 is formed to inject a viscous oil A between the chamber 511 and the yoke 52, and a rod body 53 is protruded from the outer end of the rotator 52. The rod body 53 is received by the accommodating seat 51. The bulge is protruded outwardly. In this way, when the curtain shaft 60 is in the process of winding up and dropping the curtain, the damper is engaged with the curtain shaft 60 through the coupling seat 54 by the damper 50. The rotation seat 52 of the 50 and the rod body 53 are combined with the return spring rod member 61, so that the curtain shaft 60 needs to be driven to rotate the accommodating seat 51 during the rotation. The oil absorbing material A is injected between the chamber 511 of the accommodating portion 51 of the damper 50 and the oil-receiving portions 522 of the rotator 52, so that the oil material A needs to pass through during the rotation of the accommodating seat 51. The gap between the chamber 511 of the seat 51 and each of the ribs 521 of the swivel 52 increases the oil-repellent area by the blocking effect of the ribs 521, and allows the rotation to have an excellent damping force. Relatively, it can improve its buffering effect; it is not difficult to find out that there are some shortcomings in the above-mentioned conventional structure. The main reason is as follows: The conventional damper 50 uses the damping oil A and the rib 521. The damping deceleration effect is achieved. Under long-term use, the oil material A is easily leaked, which not only affects the cleanliness and cleanliness of the curtain, but also fills the oil in time with the refilling, which is not practical.

In view of this, the inventors have been engaged in the manufacturing development and design experience of related products for many years, and after detailed design and careful evaluation of the above objectives, the present invention has finally become practical.

According to the conventional roller blinds, when the coiler is not provided with any cushioning structure, the roller blind will generate a strong momentary retracting force during the winding, which will not only cause excessive curtains. The impact of the impact of damage, on the other hand, it is easy to cause operator injury.

Furthermore, another conventional damper uses a damping oil to cooperate with each rib to achieve a damping deceleration effect. Under long-term use, it is easy to cause oil leakage, which not only affects the cleanliness and cleaning of the curtain, but also presses on the other hand. When it is combined with refilling and filling the oil, it is not practical, and this is the technical problem to be solved by the present invention.

Therefore, the present invention provides a curtain curtain deceleration structure comprising: a casing, a drive shaft and a shaft, the casing having a hollow chamber having a cavity and forming an opening at one end and a piercing at the other end a through hole is communicated with the chamber, and a perforation is provided by the outer peripheral wall, and For the assembly of a driving pin, a driving shaft has a receiving groove in the axial direction, and an interlocking gasket is arranged on the inner side wall of the receiving groove, and then is combined with an inner shaft tube, and the inner diameter of the inner shaft tube is formed. The utility model has a circular hole shape, and an outer circumferential wall of the driving shaft is provided with an oblique guiding rail, and a clutch tooth is arranged at one end portion, a shaft rod has an axial center section, and a deceleration unit is closely arranged, and the deceleration unit protrudes with a tilting The lever and the clutch shaft of the drive shaft abut against each other, and then the non-cylindrical displacement rod portion extends from the shaft core portion for the inner shaft tube assembly limitation, so that the drive shaft can slide and displace on the displacement rod portion, and finally drive The shaft and the shaft rod are assembled into the housing of the outer casing, and the oblique guide rail of the driving shaft is opposite to the perforation of the outer casing, and is further restricted by the insertion of the driving pin. With the above structure, a curtain curtain deceleration structure can be completed.

The invention provides a deceleration device, which utilizes the forward and reverse movements generated when the curtain surface of the curtain unit is rolled, so that the deceleration device is formed in a state of being disengaged or decelerated inside the curtain unit, so that the curtain curtain is retracted and recovered. When the deceleration device has a deceleration state, the speed of the curtain winding is reduced, thereby increasing the safety of the use of the curtain unit, and avoiding the doubt of the manipulation of the curtain, and having practicality.
