Description of the Invention: [Technical Field] The present invention relates to a brake crying pull, such as a high load bearing reel brake for driving a reel take-up roller blind. [Prior Art] Referring to Fig. 1 and Fig. 2, for example, the Ο-brake 2 of the drive-discussion of the Mu-reel il roll and the roller blind 12 is mainly composed of _ ▲ 丄 ± Λ and anti-21, the tooth is fixed a shaft seat 22 of the housing 21, a ring bundle 22 w - μ Ί elastic member 23, a chain ring 24 surrounding the elastic π member 23 and rotatably disposed in the ramming cliff 21 The shaft member 22 can be movably engaged with the shaft seat 22, and the collar 24 can be inserted and the bead chain 26 of the housing 21 can be inserted. # - "不缝26.

The shaft member 25 is synchronously rotated to drive the roller, because the brake 2 is generally It is made of plastic. Therefore, for 201100624, the shaft seat 22 is prevented from being damaged or cut and the elastic member 23 is prevented from being rotated. Therefore, the elastic element with strong elastic force (tightening force) cannot be applied. Piece 23, there is a lack of insufficient tightening force, only small or lightweight roll I 12 can be used. If the large or heavy roller blind 12' is used, the reel u can easily be driven in the reverse direction (four) 7" 23 and the link 24, the roller blind 12 is hung down and the method is stabilized in the current situation. [Explanation] The purpose of this month is to provide a high load-bearing reel brake capable of improving the load capacity. The invention relates to a high load-bearing reel brake, which is coupled to a reel, the brake comprising a housing, a positioning group, a planetary wheel set, and a driving group. The positioning group has a (4) threaded to the housing - a shaft seat, a shaft seat and a set of rings engaged with the shaft seat, and a ring bundle of the ring to the ring. The sinusoidal gear set is rotatably disposed in the housing An internal U-position, a group, the driving group having a main body driving the planetary gear set driven by the planetary gear set and dialing the elastic element to loosen the collar, and the (four) coupling of the passive component and The reel is blocked by a transmission member of the elastic member. The effect of the present invention is in the planetary gear set. The above-mentioned and other technical contents of the present invention can be improved by reducing the setting of the collar and enhancing the collision of the elastic member. Features and effects, which will be apparent from the detailed description of a preferred embodiment of the reference drawings, will be apparent from 201100624. Referring to Figures 3, 4 and 5, the preferred embodiment of the high load bearing reel brake of the present invention comprises a housing 3, a group 4, a planetary gear 5, and a driving group 6. The soft seat 3 has a slot 31 formed on an inner surface, formed on one side and communicating with the chamber 31. Opening σ 32, and a first annular groove 33 formed on the inner surface and surrounding an axis X. The positioning group 4 has a ring 42 that is fastened to the shaft seat 41 of the housing 3, the ring (four) shaft seat 41, and an elastic member of the ring bundle. The shaft seat 41 is made of plastic material, and And a pair of elastic snaps 413 extending along the axis X, and a plurality of engaging portions 4ΐ4 formed on the outer surface of the branch body and having a convex shape. The collar 4 has a plurality of matching portions 421 formed on an inner surface and engaging with the engaging portions 414; This is a strong secret - the number of the batch is 431. The movable element U has a separation-distance. The planetary gear set 5 is a slidable inner ring and has a circumference around the shaft seat 41. 41: the housing 3 of the housing 3 is externally toothed ring "--tooth 2 2 An outer ring gear 51, a plurality of planetary teeth surrounding the ji, the outer ring gear 52, 51 mesh with the J ω 竿 net j. s inner ring gear, 鲞 S 9 1 η ', formed in a The plurality of grooves 52 of the outer surface and the plurality of recesses surrounding the axis have an active:; two-ring rib 522 on the opposite side. Rhododendron 丄i: cattle 61, a passive member 02, and a turbulent member 63. The active member 61 is in the concave shape of the permanent transmission ring 52, and the #5211+ is a bead chain, which is a sleeve-to-W genus and has the housing 3 through the opening 02. The disk holder 621 of the special star gear 53 and the sleeve 412 of the shaft seat 201100624 41 and surrounding the elastic member 43 are formed on the sleeve 622 and defined with - The two dialing portions 624 of the hollow portion (2) and the second ring groove 625 formed on the inner surface of the disk holder 621 around the axis X. The bell hollow portion 623 is a protruding end 431 exposing the elastic member 43. The department seems to be forced to The first element slot 625 is respectively engaged with the ring ring 522 of the inner ring gear η. The transmission member 63 is engaged with the passive member Q. And having a ring wall 631 of the axis X, a perforation 632 extending through the axis and for the pair of latches 413, and an inner surface formed on the ring wall (3) to protrude from the elastic member 43 Between the ends 431 - the limiting portion ❿ the preferred embodiment is that the transmission member 63 is coupled with the rotating shaft Η to drive the rotating shaft 71 to roll and release a roller blind D. When, 5, and 6 and FIG. 7, when the driving member 6! is not subjected to an external force, the collar 42' is tightened and the passive portion 62 is stabilized by the dialing portion 624' of the protruding end (3) J 4 of the moving member 62 In the current situation, the moving member 61 is driven by an external force to drive the inner ring gear 52 forward or the (four) ring 52 will drive the planetary members during the spinning process to rotate the active member 62, thereby 'passively meaning★ In the middle of the control unit 624, the elastic member 43 is controlled to be slid, and the elastic member 43 is released from the collar and the shovel, 633 and the elastic member are rotated around the shaft 41. 43* The transmission member 63 of the last name transmission member 63 restricts the relationship between the transmissions Μ X % 431, and the timing of the rotation of the moving member 63 is rotated, thereby achieving the purpose of driving the rotating shaft and releasing the roller blind 201100624 72. The high load bearing reel brake of the present invention has the following advantages and effects: 1. Since the side collar 42 is made of a metal material, it has higher strength and hardness than plastic, and therefore can withstand strong elastic force (tightening force). The elastic member 43 is not only suitable for the large or heavy-weight roll I 72, but also can maintain the stability of the reel 71 in the case where the tightening force 足够 足够 is sufficient, thereby improving the load carrying capacity of the reel 71. 2.4 The comet gear set 5 is a gear structure with small volume, light weight, high transmission efficiency and large load capacity, which not only can increase the torque, but can also drive the reel 71 in a labor-saving manner. Therefore, the present invention is used. High elastic: (elastic force) elastic member 43, but can improve the transmission efficiency under the problem of reducing the active member "driver", without affecting the convenience and smoothness of the invention in the operation of the operation. However, the above is only the preferred embodiment of the present invention, and is not intended to limit the scope of the present invention to the extent that the invention is in accordance with the present invention: Variations and modifications are still within the scope of the patents of this month.
