After learning the technical scheme disclosed in the invention publication text, the inventor of the present invention makes improvements on the basis of the technical scheme, mainly aiming at the improvement of the needle head, and the rest of the technical scheme is the same as the technical features disclosed in the prior art, and is not repeated in the present application.

An embodiment 1 of a glass curtain wall sunshade device comprises a needle and a needle head 2 connected with the needle, as shown in figures 1-6, the needle head comprises a top pressing barrel 3, the lower end of the top pressing barrel is frosted to increase the friction force at the lower end of the top pressing barrel, a top push rod 4 is arranged in the top pressing barrel in a sliding mode, a spiral groove 5 is axially arranged on the outer surface of the top push rod, a pressing and rotating mechanism with the upper end connected with the needle is sleeved on the periphery of the top pressing barrel, the top pressing barrel is provided with a guide through groove 6, the pressing and rotating mechanism is provided with a guide head 7 which penetrates through the guide through groove to be matched with the spiral groove, a certain friction force is formed between the guide head 7 and the spiral groove to enable the guide head to drive the top push rod to move downwards together, the guide head 7 can be a telescopic rod structure or an elastic rod capable of being bent elastically, the lower end of the top push rod is provided with a thread fixing mechanism 8 for fixing the head end of a thread rope, the upper end is provided with an elastic piece 9 for returning the ejector rod.

The pressing and rotating mechanism comprises an upper guide ring 10 and a lower guide ring 11 which are sleeved on the periphery of the jacking cylinder body, the upper guide ring 10 is in sliding fit with the jacking cylinder body, the lower guide ring 11 is in rotating fit with the jacking cylinder body and cannot move axially relative to the jacking cylinder body (the conventional technical means are not repeated), at least three spiral elastic strips 12 are distributed between the upper guide ring and the lower guide ring, the upper ends and the lower ends of the spiral elastic strips are distributed in a staggered and spaced mode on the projection of the horizontal plane, the middle of each spiral elastic strip protrudes outwards to enable the pressing and rotating mechanism to be in a spindle shape with two thin ends and a thick middle part, an offset surface 13 used for lifting a guide head upwards is arranged at the lower end of each guide through groove, the thread fixing mechanism comprises a magnet 14 embedded at the lower end of the jacking rod, and the magnet is fixed with the jacking rod in a magnetic attraction mode.

An embodiment 2 of the glass curtain wall sunshade device is different from the embodiment 1 in that an upper guide ring is provided with a connecting cylinder 15 which is fixedly connected with a threading needle, and the connecting cylinder is provided with a connecting thread 16; the guide head is of a spring telescopic rod structure and specifically comprises a support barrel and a rod body in sliding fit with the support barrel, and a spring for enabling the rod body to be far away from the support barrel is arranged between the rod body and the support barrel; the upper end of the jacking cylinder body is provided with a baffle 17 for preventing the guide head from being separated from the guide through groove, the elastic part is a spiral compression spring, and the lower end of the jacking rod is a hemispherical surface.

In other embodiments, sponge is filled between the spiral elastic strip and the jacking cylinder body, so that a groove for accommodating the cord is formed between the sponge and two adjacent spiral elastic strips, and the sponge plays a role in supporting the cord.

When the device is used, the thread end of the thread rope is placed between the magnet 14 and the ejector rod 4 to be fixed by means of the magnetic attraction force of the magnet 14 and the ejector rod 4, the thread rope passes through a gap between adjacent spiral elastic strips, then the needle is penetrated to drive the needle head to move downwards, when the jacking cylinder body 3 moves to the upper surface of the locking block, the locking block is pushed and stops moving downwards, and at the moment, the spiral elastic strips 12 are positioned between the ejector rods; because the top pressure cylinder 3 stops moving downwards, when the needle threading continues to move downwards, the needle threading presses the connecting cylinder 15 and the upper guide ring 10 downwards to enable the spiral elastic strip 12 to be compressed axially and rotate circumferentially, and at the moment, the spiral elastic strip 12 also pushes the ejector rod to move towards two sides along with circumferential outward expansion, because the upper guide ring 10 is in sliding fit with the top pressure cylinder, the lower guide ring 11 is in rotating fit with the top pressure cylinder, and the upper guide ring 10 and the top pressure cylinder cannot move axially relative to each other, the lower guide ring 11 finally rotates; because there is certain frictional force between the guide head 7 and the spiral groove 5, the guide head can drive the ejector rod to move downwards together, when the lower end of the ejector rod 4 is pushed between two locking blocks and does not move downwards, the guide head 7 moves downwards and drives the ejector rod 4 to rotate through the spiral groove 5, and at the moment, the cord is clamped by the adjacent spiral elastic strips, the rotating direction of the ejector rod 4 is opposite to that of the guide ring 11, the cord close to the magnet 14 is twisted along with the rotation of the ejector rod 4, the length of the cord is forced to be shortened along with the twisting of the cord, the cord end is forced to be separated from the magnet 14, the portion of the cord close to the magnet 14 is curled into a cord knot by the reverse twisting force of the twisting, at the moment, the guide head 7 moves downwards to the offset plane 13, the offset plane 13 is obliquely arranged to enable the guide head 7 to move along the offset plane 13 so as to be separated from the spiral groove 5, therefore, the spiral groove 5 is separated from the limit of the guide head 7, so that the ejector rod 4 moves upwards under the action of the elastic piece 9 to reset and is separated from the two locking blocks, the spiral elastic strip 12 is continuously pressed downwards, the circumferential expansion of the spiral elastic strip 12 drives the ejector rod to move towards two sides to the limit position, and then the two locking blocks are close to each other to clamp the knot.

The above description is only for the purpose of illustrating the preferred embodiments of the present invention and is not to be construed as limiting the invention, and any modifications, equivalents, improvements and the like that fall within the spirit and principle of the present invention are intended to be included therein.
