[0025] The present invention is described in detail below in conjunction with specific embodiments.

[0026] In the present utility model, when directional words appear, they are used to facilitate the description of the utility model and simplify the description, rather than to indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and cannot be understood as limiting the specific protection scope of the present utility model.

[0027] In the present invention, unless otherwise specified and limited, when terms such as "disposed on", "connected" and "connected" appear, these terms should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can also be a mechanical connection; it can be directly connected, or it can be connected through an intermediate medium, or the two elements can be internally connected. For those skilled in the art, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0028] like Figures 1 to 4 As shown, a double-row four-wheel fixed-distance ball bearing of a curtain track includes: a ball frame 1 is composed of a ball frame end 110 and a ball frame base 109, the ball frame end 110 is connected to the ball frame base 109, the ball frame 1 is a one-piece symmetrically formed part along the center line, and the ball frame end 110 is provided with a pulley baffle 101, an anti-rope top pin 102, a rivet shaft hole 103, a card slot 104, and a wire groove 105. There are two rivet shaft holes 103, which are symmetrically arranged on the left and right sides of the ball frame end 110 along the center line of the ball frame 1, and the ball frame base 109 A curtain support platform snap-in 107 and a guide chamfer 108 are provided on it, and a hollow part 106 is provided at the junction of the end 110 of the ball frame and the base 109 of the ball frame, so that the ball frame can save more material costs; the rivet 301 is arranged in the rivet shaft hole 103, and pulleys 3 are arranged at both ends of the rivet 301; the rivet 301 passes through the pulley 3 and is inserted into the rivet shaft hole 103 and riveted and fixed to the ball frame 1, and the fixed distance bead 4 is arranged on the card slot 104; the curtain hanging buckle support platform 2 is composed of a hanging buckle card interface 201 and a hanging buckle slide groove 202, and the hanging buckle card interface 201 is connected to the curtain hanging buckle support platform 2.

[0029] The clamping slot 104 is arranged at the top of the ball bearing frame 1 . The clamping slot 104 is arranged between the two rivet shaft holes 103 . The clamping slot 104 is a double half-moon inverted T-shaped structure. The distance bead 4 is clamped in the clamping slot 104 .

[0030] The pulley baffle 101 is symmetrically arranged on the two sides of the front end and the rear end of the bead frame end 110, and the anti-rope pin 102 is arranged in the middle of the bead frame end 110. The anti-rope pin 102 is arranged on both sides of the front end and the rear end of the bead frame end 110. The wire groove 105 is arranged along the outer wall of the bead frame end 110. The guide chamfer 108 is arranged on both sides of the front end and the rear end of the bead frame base 109. The curtain support platform clamp 107 is funnel-shaped. There is a gap between the rivet 301 and the pulley 3 and the bead frame 1. The hook card interface 201 and the hook slide 202 constitute an I-head card interface, the bead frame end 101 is arranged in the curtain track 5, and the bead frame end 110 is supported in the curtain track 5 through the pulley 3.

[0031] During the specific implementation: the end 110 of the ball frame is arranged in the track 4, and the four pulleys 3 arranged at the end 110 of the chain frame are supported on the curtain track 5, so that the ball frame 1 can slide more smoothly, stably and more balanced, and it is very good to prevent the ball frame 1 from swinging left and right to cause the curtain buckle support 40 to collide with the curtain track 5 to generate noise, and the curtain pulley baffle 101 and the anti-rope top pin 102 are flush with the highest tangent of the arc of the pulley 3, and the pulley baffle 101 and the anti-rope top pin The clearance between the two pulleys is not more than 0.7 mm, which prevents the distance bead rope 401 from being entangled with the pulley 301 during production or assembly. The slot 104 is provided with a chamfer to facilitate the assembly of the distance bead 4. The double semi-moon inverted T-shaped slot 22 holds the distance bead 4 tightly and prevents the distance bead 4 from loosening. A guide groove 105 is provided to arrange the distance bead rope 401 neatly and orderly. The edge of the end 110 of the bead frame is provided with a guide chamfer to prevent the bead frame 1 from shaking during sliding. The curtain rail 5 is hit hard and noisy. The head of the curtain hook support 2 is an I-shaped head design. The front platform of the curtain hook support 2 is a taper design with a low outside and a high inside. The inner height of the curtain support bayonet 107 is an interference fit with the I-shaped head of the curtain hook support 2. There is a cavity above the curtain support bayonet 107. When the hook clamp interface 201 is connected to the curtain support bayonet 107, the top is set in the cavity. After passing through the I-shaped head of the curtain hook support 2 for assembly, it is not easy to loosen out of the curtain support bayonet. The funnel design of the opening 107 of the curtain support is snapped into the funnel design of the opening 107 of the curtain support. The minimum position of the funnel is an interference fit with the neck of the I-head of the curtain hook support 2. After the I-head of the curtain hook support 2 is snapped in, it can be well fixed on the center hole of the curtain support opening 107. The I-head of the curtain hook support and the center hole of the curtain support opening 107 are an interference fit. The I-head of the curtain hook support can be rotated at will on the curtain support opening 107 of the curtain hook support 2.

[0032] In the absence of conflict, the above-mentioned embodiments and features thereof may be combined with each other.

[0033] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the utility model, rather than to limit the protection scope of the utility model. Although the utility model has been described in detail with reference to the preferred embodiments, ordinary technicians in this field should understand that the technical solution of the utility model can be modified or replaced by equivalents without departing from the essence and scope of the technical solution of the utility model.
