Description

Technical Field

[0001] The utility model relates to the technical field of lifting type curtains, in particular to a fixing seat of a lifting type rolling curtain. Background Art

[0002] The existing lifting curtain includes a fixed seat, a curtain, a head and a bottom frame. A rotatable reel is installed in the fixed seat, a reel for storing the reeling force is installed in the reel, the curtain is wound on the reel, the head is plugged into the reel and can transmit torque, and end caps are inserted at both ends of the fixed seat. The fixed seat is generally made of aluminum alloy profiles, and the fixed seat is a door-shaped structure. The fixed seat of this lifting curtain has the following technical defects when used: since the bottom of the fixed seat is a plane, the outer side of the bottom of the fixed seat is provided with a mounting groove for placing the clamping part, the two corners above the inner wall of the fixed seat are arc transitions and are provided with cavities, the end caps are inserted in the cavities at both ends of the fixed seat, and the front and rear sides of the fixed seat are extended with side panels. The bottom of the fixed seat has a certain width. Due to structural reasons, the rigidity of the bottom of the fixed seat is poor. During processing, assembly, transportation and use, the bottom of the fixed seat is prone to bending and deformation (the two side panels move inward), causing the end cover to twist and deform. The assembly accuracy of the reel is difficult to meet the design requirements, the curtain is not rolled up and put down smoothly, and even the plug-in parts on the end cover are broken and damaged. Summary of the invention

[0003] In order to solve the problem that the bottom of the fixing seat of the existing liftable curtain is prone to bending and deformation, the utility model provides a fixing seat for a liftable roller blind. The fixing seat of the liftable roller blind adopts a double-layer structure, and the inner layer is arched, which enhances the rigidity. The fixing seat body will not bend or deform, and raw materials are also saved. After the end cover, roller and other components are assembled, a higher assembly accuracy can be achieved. The curtain can be rolled up and put down without jamming, and the curtain can be raised and lowered smoothly.

[0004] The technical solution of the utility model is: a fixing seat of a lifting roller shutter, including a fixing seat body and an end cover, wherein the fixing seat body is an integrated structure, and the fixing seat body includes an inner layer and an outer layer, wherein the inner layer is arched upward in an arc shape, and an installation groove for accommodating a clamping part is provided at the outer center of the inner layer, and the outer layer extends horizontally from the installation groove and transitions through a right-angle arc segment to the lower end of the inner layer.

[0005] A cord snap-in groove is provided on one side of the inner layer.

[0006] The upper outer contour of the end cover matches the cross-sectional outer contour of the fixing seat body, and the lower edge of the end cover is arc-shaped, and the arc curvature of the lower edge of the end cover is consistent with the arc curvature of the inner layer arching upward.

[0007] The utility model has the following beneficial effects: due to the adoption of the above technical scheme, the fixing seat body is composed of a double-layer structure of an inner layer and an outer layer, and the inner layer is arched upward in an arc shape, and the inner layer has a better force-bearing structure. At the same time, under the action of the outer layer structure, the rigidity of the fixing seat body is enhanced, and the fixing seat body will not bend or deform. At the same time, raw materials are saved. After the end cover, reel and other components are assembled, a higher assembly accuracy can be achieved, the curtain can be rolled up and put down without jamming, and the curtain can be raised and lowered smoothly. BRIEF DESCRIPTION OF THE DRAWINGS

[0008] Attached Figure 1 It is a structural sectional view of the fixing seat body 1 in the utility model.

[0009] Attached Figure 2 It is a structural schematic diagram of the end cover 2 of the utility model.

[0010] In the figure, 1-fixed seat body, 2-end cover, 3-inner layer, 4-outer layer, 5-installation groove, 6-right-angle arc segment, 7-cord clamping groove. Implementation

[0011] The utility model is further described below in conjunction with the accompanying drawings:

[0012] Depend on Figure 1-2 As shown, a fixing seat of a lifting roller blind includes a fixing seat body 1 and an end cover 2. The fixing seat body 1 is an integrated structure. The fixing seat body 1 includes an inner layer 3 and an outer layer 4. The inner layer 3 is arched upward in an arc shape. The outer center of the inner layer 3 is provided with a mounting groove 5 for placing a clamping member. The outer layer 4 extends horizontally from the mounting groove 5 and transitions to the lower end of the inner layer 3 through a right-angle arc segment 6. Due to the adoption of the above technical solution, the fixing seat body 1 is composed of a double-layer structure of an inner layer 3 and an outer layer 4, and the inner layer 3 is arched upward in an arc shape. The inner layer 3 has a better force-bearing structure. At the same time, under the action of the outer layer 4 structure, the rigidity of the fixing seat body 1 is enhanced, and the fixing seat body 1 will not bend and deform. At the same time, raw materials are saved. After the end cover 2, the reel and other components are assembled, a higher assembly accuracy can be achieved. The curtain cloth is rolled up and put down without jamming, and the curtain cloth is lifted and lowered smoothly.

[0013] One side of the inner layer 3 is provided with a curtain snap-in groove 7. The curtain snap-in groove 7 is mainly used for double-layer rolling curtains.

[0014] The upper outer contour of the end cover 2 matches the cross-sectional outer contour of the fixing seat body 1, and the lower edge of the end cover 2 is arc-shaped, and the arc curvature of the lower edge of the end cover 2 is consistent with the arc curvature of the inner layer 3 that arches upward. The arc-shaped lower edge of the end cover 2 will not cause the curtain to be hung or rubbed, and also makes the overall external shape simple and neat, while saving raw materials.
