Technical Field

[0001] This utility model belongs to the field of venetian blind technology, and specifically refers to an embedded head control mechanism for venetian blind track beams. Background Technology

[0002] Venetian blinds are widely used in the field of architectural window and door shading due to their flexible light-adjusting function and elegant modern aesthetics. The core driving components of Venetian blinds usually include a track beam with a mounting cavity, a built-in cord winder, and end caps and spools installed at both ends of the track.

[0003] In traditional Venetian blind track designs, the head-locking assembly is typically integrated or fixedly connected to the end cap structure at one end of the track. This end cap not only needs to seal the end of the track but also needs to secure the head-locking mechanism. Because different series, colors, or functions of Venetian blinds vary in the cross-sectional shape, size, and color of their track, the head-locking mechanism needs to be designed and manufactured to match the end cap, increasing the number of matching head-locking molds and significantly raising production costs. Utility Model Content

Detailed Implementation

[0018] The present invention will be further described below with reference to the accompanying drawings and specific embodiments. See also: Figure 1 — Figure 3 : Example 1: As Figure 1 and Figure 2 As shown, an embedded head control mechanism for a Venetian blind track beam includes a track beam 1 with an upper opening. Both ends of the track beam 1 are provided with end cap openings 10, and each end cap opening 10 is covered with an end cap 2 of the same structure. A head control 3 is provided inside the track beam 1, and a limiting end 30 is provided on the side wall of the head control 3. A bead pull groove 11 is provided on the front side of the track beam 1, and the bead pull sprocket on the head control 3 is aligned with the bead pull groove 11. A guide sleeve 4 for guiding the bead pull is provided on the bead pull groove 11.

[0019] Preferably, the limiting end 30 includes a limiting groove 31 formed on the front side of the cutting head 3; the rear side of the guide sleeve 4 is provided with a limiting protrusion 40. When the guide sleeve 4 is installed in place, the limiting protrusion 40 is embedded in the limiting groove 31 to fix the cutting head 3 in the track beam.

[0020] Preferably, the guide sleeve 4 includes a plug sleeve 41 that is inserted into the bead groove 11, and the limiting protrusion 40 is formed on the left and right sides of the plug sleeve 41; the upper and lower side walls of the plug sleeve 41 are both formed with limiting barbs 42.
