Detailed Description

The utility model is further illustrated by the following specific figures and examples.

As shown in fig. 1 to 4, an embodiment discloses an integrated retractor, which includes a hauling rope 1, a pulley 2 and a hauling weight 3, wherein one end of the hauling rope 1 is provided with a multi-section movable buckle assembly for connecting a hauling bow 7, the multi-section movable buckle assembly includes a first connecting buckle 4, a second connecting buckle 5 and a plurality of mutually connected quick-release movable buckles 6 located therebetween, the first connecting buckle 4 is used for connecting the hauling bow 7, the second connecting buckle 5 is connected with one end of the hauling rope 1, the other end of the hauling rope 1 is provided with a third connecting buckle 8 for connecting the hauling weight 3, and the third connecting buckle 8 is a connecting buckle capable of opening and closing; the traction weight 3 comprises a weight seat 9 and a plurality of weights 10, a vertical rod 11 is arranged at the center of the top of the weight seat 9, a buckling hole 12 for butting with the third connecting buckle 8 is formed in the upper end of the vertical rod 11, the weights 10 are of an annular structure with a through hole in the center, and the weights 10 are sleeved on the vertical rod 11.

When the multi-section movable buckle component is used, the pulley 2 is fixed on a traction bed, the first connecting buckle 4 in the multi-section movable buckle component is connected to a traction bow 7, the second connecting buckle 5 in the multi-section movable buckle component is connected with one end of a traction rope 1, the other end of the traction rope 1 bypasses the pulley 2 and then naturally hangs, and then the quick-release movable buckle 6 in the multi-section movable buckle component is increased or reduced according to the individual condition of a patient, so that the other end of the traction rope 1 is proper in height; then, a weight 10 with proper weight is configured for the traction weight 3 according to the traction requirement, and the third connecting buckle 8 is connected with a buckle hole 12 at the upper end of the vertical rod 11, so that the installation of the traction weight 3 is realized. Because the length of the multi-section movable buckle component is adjusted by increasing or decreasing the quick-release movable buckle 6, the trouble and inconvenience caused by repeatedly knotting the rope to increase or decrease the length in the prior art are overcome. Because the traction weight 3 is not of a side opening structure, the risk that the weight 10 accidentally falls is avoided, and the safety is higher. When the traction weight needs to be increased or decreased, the third connecting buckle 8 can be quickly opened to be separated from the vertical rod 11, so that the weight 10 of the balance weight can be conveniently increased or decreased.

As shown in fig. 1 and 2, in the present embodiment, the third connecting buckle 8 is a rotary type connecting buckle of an openable speed switch. The first and second coupling links 4 and 5 have the same structure as the third coupling link 8. Therefore, the multi-section type movable buckle component can be quickly straightened, and the bending and twisting of the multi-section type movable buckle component and the traction rope 1 are avoided. The rotary-type connector fastener may be a conventional one in the art.

The quick-release movable buckle 6 of the utility model can also adopt a key buckle product in the prior art. However, such products in the prior art are generally large-end-small structures, and the stability of traction is affected by direct adoption. Therefore, the present embodiment provides an optimized quick-release movable buckle 6, the structure of which is shown in fig. 1 and fig. 3, the quick-release movable buckle 6 includes a buckle ring 61 and a buckle tongue 62, the buckle ring 61 is an ellipse with a notch on one side, the buckle tongue 62 is installed in the notch, one end of the buckle tongue 62 is hinged to one end of the buckle ring 61 through a pin shaft 63, the other end of the buckle tongue 62 is provided with a bayonet, an anti-release bayonet 64 is installed in the bayonet, the other end of the buckle ring 61 is provided with a flat head 61a matched with the bayonet, and the inner side surface of the flat head 61a is provided with an arc-shaped anti-release positioning slot 61b matched with the anti-release bayonet 64. With the arrangement, when the quick-release movable buckle 6 is closed, the bayonet is matched with the flat head 61a, so that the buckling tongue 62 can be prevented from being inclined; the anti-falling bayonet lock 64 is matched with the U-shaped anti-falling positioning bayonet lock 61b, so that the quick-release movable buckle 6 can be prevented from being opened accidentally.

In addition, as shown in fig. 3, in this embodiment, in order to facilitate opening the quick-release movable buckle 6, an anti-slip sleeve 65 is further fixedly sleeved on one side of the buckle ring 61 opposite to the notch. The traction rope 1 of the present invention is preferably a lightweight, strong plastic cord.
