The upper beam 100 is an important supporting member of the blind, and referring to fig. 1, the upper beam 100 is mostly of a standard "U" shape structure, and both free ends of the upper beam 100 are bent inward.

In order to enable the blind to be opened and closed normally, a stay fixing seat is required to be arranged in the upper beam 100, and the stay is effectively wound and guided by the fixing seat, and the dotted line in fig. 1 is a guide line for installing the fixing seat on the upper beam 100, that is, the installation of the upper beam 100 and the fixing seat is completed in such a way.

In order to further show the structure of the fixing seat, referring to fig. 2, the fixing seat includes a seat body 11 and a receiving portion 12, the seat body 11 is a plate-shaped structure, and a rope threading hole 111 for a rope to pass through is formed in the seat body 11.

The bearing part 12 is located above the rope threading hole 111, fixed with the seat body 11, and used for bearing the rope penetrating through the rope threading hole 111.

The receiving portion 12 includes a winding shaft 121 capable of elastically contracting and a supporting base 122 fixed to the base body 11.

The number of the support platforms 122 is two, the two support platforms 122 are symmetrically arranged on two sides of the rope threading hole 111, and a through strip-shaped groove 122-1 is transversely arranged on the support platforms 122.

The winding shaft 121 is located between the two support tables 122, and two ends of the winding shaft 121 respectively penetrate through the strip-shaped groove 122-1.

The bobbin 121 having elastic contraction as described above means that the bobbin 121 can be compressed and shortened by pressing; the extension can be reset under the condition of not pressing.

Specifically, referring to fig. 3 to 4, the winding shaft 121 includes a winding portion 121-1, a shaft end portion 121-2 disposed at both ends of the winding portion 121-1, and an elastic portion 121-3 connecting the winding portion 121-1 and the shaft end portion 121-2, wherein the winding portion 121-1, the elastic portion 121-3, and the shaft end portion 121-2 are coaxially disposed.

The winding portion 121-1 is used for winding a pull rope, the shaft end portion 121-2 is used for penetrating the strip-shaped groove 122-1, a compression spring is arranged in the elastic portion 121-3, and the shaft end portion 121-2 is elastically connected with the compression spring.

Thus, when the bobbin 121 is installed in the strip-shaped groove 122-1, the shaft end part 121-2 on one side is firstly inserted into one strip-shaped groove 122-1, then the shaft end part 121-2 on the other side is squeezed by fingers, and the compression spring is compressed, so that the whole length of the bobbin 121 is shortened; at the moment, the compressed shaft end part 121-2 is pushed to the direction of the strip groove 122-1 to push the compressed shaft end part into the other strip groove 122-1; the compression spring is reset to restore the original length of the bobbin 121, so that both ends of the bobbin 121 are inserted into the bar-shaped grooves 122-1.

Thus, the purpose can be achieved by directly adjusting the spool 121 regardless of the adjustment of the pull cord.

For example, referring to fig. 5, when the pull rope needs to be adjusted to the left, an operator may adjust and slide the spool 121 to the left to position the spool at the left side of the strip-shaped groove 122-1, and then wind the pull rope passing through the rope threading hole 111 on the winding portion 121-1 of the strip-shaped groove 122-1; referring to fig. 6, when the pull rope needs to be adjusted to the right, an operator can adjust and slide the spool 121 to the right, so that the spool is positioned at the right side of the strip-shaped groove 122-1, and then the pull rope is wound on the spool 121-1.

Preferably: referring to fig. 7, the opposite sides of the two support bases 122 are provided with guide grooves 122-2 for guiding the bobbin 121 to be mounted to the bar grooves 122-1, and the bobbin 121 is advantageously mounted by the guide grooves 122-2.

Referring to fig. 2, the seat body 11 includes a bottom plate 110 and side plates 112 disposed at two sides of the bottom plate 110, the bottom plate 110 and the two side plates 112 together form the seat body 11 to be a "U" shaped structure, the above-mentioned rope threading hole 111 is disposed at the center of the bottom plate 110, and the whole receiving portion 12 is disposed on the upper end surface of the bottom plate 110.

Preferably: a rib plate is connected between the bottom plate 110 and the side plate 112 for reinforcing the connection therebetween.

Preferably: referring to fig. 2 and 8, a strip-shaped mounting hole 113 is formed in the bottom plate 110, an extended edge 113-1 protruding outwards is formed at an edge of the mounting hole 113, and the extended edge 113-1 is located on a lower end surface of the bottom plate 110.

The stability of the installation of the whole fixed seat is further ensured by utilizing the outward convex extension edge 113-1 to be matched with a strip-shaped hole (not shown) corresponding to the upper beam.

It should be noted that there are no specific structures in the above description, and it will be apparent to those skilled in the art that various modifications, decorations, or changes can be made without departing from the technical principles of the present invention; such modifications, variations, or combinations, or applying the concepts and solutions of the technology directly to other applications without further modifications, are intended to be within the scope of the present technology.
