Detailed Description

Reference will now be made in detail to embodiments of the present invention, examples of which are illustrated in the accompanying drawings, wherein like reference numerals refer to the same or similar elements or elements having the same or similar function throughout. The embodiments described below with reference to the drawings are exemplary and intended to be used for explaining the present invention, and should not be construed as limiting the present invention. In the description of the present invention, it should be understood that the terms "upper", "lower", "front", "upper surface", and the like indicate orientations or positional relationships based on the orientations or positional relationships shown in the drawings, and are only for convenience of description and simplification of the description, but do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and thus should not be construed as limiting the present invention.

Referring to fig. 1-8, the present invention provides an embodiment: a head making and a tail making for a curtain comprise a head making 10 and a tail making 11; the head making part 10 and the tail making part 11 both comprise a base 1 and angle iron 3, and the base 1 is also provided with a cavity 2 for accommodating the angle iron 3; the head making 10 also comprises a chain wheel 13 connected with the pull bead and a head making cover 15 connected with one end of the curtain scroll; the chain wheel 13 is connected with a main shaft body 12 through a planet wheel assembly, and one end of the main shaft body 12 is connected with the head manufacturing cover 15 through a first bearing 14; the tail-making 11 also comprises a linkage mechanism 9 arranged at the other end of the curtain scroll, one end of the linkage mechanism 9 is connected with a second bearing 4 arranged in the middle of the angle iron 3, and the other end of the linkage mechanism 9 is connected with the other end of the curtain scroll through a tail plug 7 arranged on the other end of the linkage mechanism 9.

In summary, the first bearing 14 is used for connecting the head making cover 15 with the main shaft body 12, so that the vibration of the head making 10 during working caused by the direct friction between the head making 10 and the angle iron 3 is avoided, and the stability of the curtain during lifting is further improved; meanwhile, the cavity 2 is used for accommodating the angle iron 3, so that the overall thickness of the head making part 10 and the tail making part 11 is reduced, and the light transmission areas on the two sides of the curtain can be effectively reduced under the condition of the same bearing rate; the linkage mechanism 9 is further connected with the angle iron 3 on the tail 11 by utilizing the second bearing 4, so that direct friction between the linkage mechanism 9 and the angle iron 3 is avoided, and the stability of the curtain during lifting can be further improved.

In addition, the device can also complete the integral replacement of the head making 10 and the tail making 11 by directly removing the angle iron 3, so that the base 1 can not be replaced to reduce the number of the holes when the curtain is replaced.

Because angle bar 3 with base 1 swing joint utilizes behind the bolt passing angle bar 3 with cavity 2 screw-thread fit, and then can with angle bar 3 direct mount on base 1, have based on this, this equipment can also be through directly tearing down angle bar 3, has accomplished the replacement of whole link gear 9, therefore when the (window) curtain was changed, can not change base 1 in order to reduce the waste of base 1.

Because the cover plate 16 is arranged between the chain wheel 13 and the head making cover 15, and the planetary wheel assembly is covered in the chain wheel 13 through the cover plate 16, the planetary wheel assembly can be protected from dust contacting with the gear, which causes the problems of gear abnormal sound and gear jamming.

In order to facilitate the assembly of the head making 10, one end of the main shaft body 12, which is far away from the angle iron 3, penetrates through the head making cover 15 and then is connected with the provided fastener 17, and the fastener 17 penetrates through the head making cover 15 and then is connected with the end face of the main shaft body 12, so that the head making cover 15 and the main shaft body 12 are convenient to disassemble and assemble, and the first bearing 14 is convenient to disassemble and assemble.

On the basis of the scheme, the linkage mechanism 9 comprises a driving part 5 linked with the tail plug 7, and the driving part 5 is connected with the tail plug 7 through a linkage shaft 6. Therefore, the two ends of the curtain reel can synchronously rotate, and the curtain provided with the braking head 10 and the braking tail 11 can lift more stably.

Further, one end of the linkage shaft 6 is provided with a toothed pin 60; the tail plug 7 is internally provided with a tooth groove 8 matched with the tooth pin 60, and the driving part 5 is matched and connected with a guide rod 61 arranged on the linkage shaft 6 through a guide groove 52. The tail plug 7 is connected with the other end of the curtain scroll, and when the tail plug 7 rotates, the guide rod 61 slides along the guide groove 52, so that the linkage shaft 6 can extend or shorten in the tail plug 7, and the distance between the tail plug 7 and the base 1 can be enlarged; therefore, the tail-making 11 can adapt to the roller shafts with different lengths, for example, if the roller shaft of the curtain is shorter, the linkage shaft 6 slides outwards, namely slides towards one end far away from the base 1; if the curtain reel is long, the linkage shaft 6 slides inwards, namely slides towards the direction of the base 1, so that the tail 11 can adapt to the change of the length of the curtain reel.

Furthermore, because the driving part 5 includes the driving wheel 50 and the sleeve 51 made integrally with the driving wheel 50, wherein the guide groove 52 is provided on the sleeve 51, and the two ends of the guide groove 52 are both provided with the positioning surfaces 53, when the guide rod 61 is inconsistent with the positioning surfaces 53, the tail plug 7 after rotating can be supported, so as to avoid the curtain reel from swinging left and right.

In particular, the number of the guide grooves 52 is three, and the positioning surface 53 on each guide groove 52 gradually increases along the counterclockwise direction, i.e. gradually moves towards the end of the sleeve 51 far away from the driving wheel 50, so that the device also has three adjustable gears.

The embodiments of the present invention have been described in detail with reference to the accompanying drawings, but the present invention is not limited to the described embodiments. It will be apparent to those skilled in the art that various changes, modifications, substitutions and alterations can be made in the embodiments without departing from the principles and spirit of the invention, and the scope of the invention is to be accorded the full scope of the claims.
