Specific implementation mode

[0025] Next, the technical solutions in the embodiments of the present application will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present application. Obviously, the described embodiments are only a part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative efforts belong to the protection scope of the present application. In addition, the technical solutions between the various embodiments can be combined with each other, but it must be based on the fact that those of ordinary skill in the art can implement it. When the combination of the technical solutions is contradictory or cannot be implemented, it should be considered that such a combination of the technical solutions does not exist and is not within the protection scope of the present application.

[0026] Refer to Figures 1-7 As shown, for the new lower cover of the guide rail, a column 2 is provided on one side of the lower cover 1 of the guide rail, and a column cover 3 detachably arranged on the column 2. The lower cover 1 of the guide rail is composed of a main body 101 and a secondary body 102 that is snap-fitted with the main body 101 to form an integral body; a fitting surface 1011 is formed on the main body 101 and on the side where the secondary body 102 is fitted, and the fitting surface 1011 is fitted with the outer side surface of the column cover 3; the bottom surface of the secondary body 102 abuts against the bottom plate 4 of the column 2.

[0027] As Figure 2 shown, among them, the fitting surface 1011 is composed of three continuous cross-sections, including a vertical surface 10111, a horizontal surface 10112, and an inclined surface 10113 for connecting the vertical surface 10111 and the horizontal surface 10112. The horizontal surface 10112 is fitted on the upper wall surface of the column cover 3, the vertical surface 10111 is fitted on the side wall surface of the column cover 3, and the inclined surface 10113 is fitted on the inclined wall surface of the column cover 3. Refer to Figure 7 In the figure, a mating surface 1021 having the same shape as the outer wall surface of the column cover 3 and the fitting surface 1011 is provided on the secondary body 102. The mating surface 1021 also includes a mating horizontal surface 10211, a mating vertical surface 10212, and a mating inclined surface 10213.

[0028] When the column cover 3 is installed on the column 2, the lower rail cover 1 only has the main body 101 part, which is abutted against the column cover 3. When the column cover 3 is not installed on the column 2, the lower rail cover 1 is composed of the main body 101 and the auxiliary body 102, and the bottom surface of the auxiliary body 102 abuts against the bottom plate 4.

[0029] To ensure the connection reliability between the main body 101 and the auxiliary body 102, a first insertion structure and a second insertion structure are provided between the main body 101 and the auxiliary body 102. The first insertion structure is arranged at the horizontal plane 10112 and the fitting horizontal plane 10212, and the second insertion structure is arranged at the vertical plane 10111, the inclined plane 10113, the fitting vertical plane 10211, and the fitting inclined plane 10213. The fit between the main body 101 and the auxiliary body 102 is an interference fit, which can prevent the detachment of the two while ensuring disassembly.

[0030] The first insertion structure includes a step groove 5 arranged on the horizontal plane 10111 and a step boss 6 arranged on the fitting horizontal plane 10211. Specifically, as Figure 6 shown, at least two groups of the step groove 5 and the step boss 6 are provided and evenly arranged at the middle position. Through the step shape, it can effectively prevent the auxiliary body 102 from moving in the longitudinal direction after being installed on the main body 101.

[0031] The second insertion structure includes a strip groove 7 arranged at the vertical plane 10111 and the inclined plane 10113, and a strip block 8 arranged at the fitting vertical plane 10211 and the fitting inclined plane 10213. Specifically, as Figure 7 shown, the widths of the strip groove 7 and the strip block 8 are relatively small. At least two groups of them are arranged at both side positions. After the auxiliary body 102 is installed on the main body 101, the strip block 8 is inserted into the strip groove 7, effectively preventing the auxiliary body 102 from moving in the transverse direction (excluding the insertion direction of the auxiliary body 102).

[0032] Furthermore, for the same purpose of preventing the auxiliary body 102 from moving in the transverse direction, side plates 9 are arranged on both the left and right sides of the auxiliary body 102. The distance between the inner walls of the two groups of side plates 9 is the same as the width of the main body 101. When the auxiliary body 102 is inserted into the main body 101, the side plates 9 can wrap the side surface of the main body 101.

[0033] Furthermore, in order to prevent jamming during insertion, chamfers 10 are arranged on the side surfaces of the step boss 6 and the strip block 8 facing the main body 101.

[0034] While ensuring strength, material waste can be reduced. A cavity 11 is provided inside the secondary body 102, and a partition board 12 perpendicular to the strip block 8 is provided at the transverse middle position of the cavity 11. In cooperation with the two groups of strip blocks 8, the strength can be ensured.

[0035] A rolling curtain device includes a guide rail 13 provided inside the column 2. The guide rail lower cover 1 is provided at the bottom end of the guide rail 13. A rolling curtain 14 is provided between the guide rails 13. The lower edge of the rolling curtain 14 is pulled to move inside the guide rail 13 and is locked when pulled to the guide rail lower cover 1.

[0036] The working process of the present utility model is divided into two cases according to whether the column cover 3 is installed on the column 2. When the column cover 3 is installed on the column 2, the fitting surface 1011 of the main body 101 is attached to the surface of the column cover 3. When the column cover 3 is not installed on the column 2, it is necessary to insert the main body 101 and the secondary body 102 into one body, then place the secondary body 102 against the bottom plate 4. After the secondary body 102 is horizontally moved towards the main body 101, the step boss 6 is horizontally inserted into the step groove 5, and the strip block 8 is inserted into the strip groove 7. With the interference fit between the two, a combined integral state is formed.

To avoid obscuring the concept of the present application, some details well known in the art have not been described. Those skilled in the art can clearly understand how to implement the technical solutions disclosed here based on the above description.
