detailed description

The specific embodiments of the present invention will be further described below in conjunction with the accompanying drawings.

The technical solution adopted by the present invention is: as shown in Figure 1 and Figure 2, a garage door motor chain head assembly that fits the C-shaped track, it includes a garage door motor shaft 1, and the garage door motor shaft 1 is located at Inside the garage door motor, a sprocket 2 is sheathed outside the circumference of the garage door motor shaft 1, and the sprocket 2 includes a sprocket sleeve 21 sleeved on the outside of the garage door motor shaft 1 and can be wound around the garage door motor shaft 1. A rotating metal sprocket 22, one side of the sprocket 21 is provided with a head piece 3 matching with the sprocket 2, the head piece 3 is engaged with the outside of the sprocket 2, and the metal sprocket 22 A chain is fitted on it, and the two ends of the head piece 3 are clamped in the C-shaped track.

Preferably, the head piece 3 includes a semicircular slot 31 above the head piece 3, a sprocket groove 32 inside the head piece 3, and chain grooves 33 on both sides of the head piece 3. The garage door The upper part of the motor shaft 1 is engaged with the semicircular slot 31 above the head piece 3, the sprocket 2 is engaged with the sprocket slot 32 inside the head piece 3, and the chain slot 32 is provided with a metal chain The chain of wheel disc 22 motions.

In this application, the sprocket 2 is set on the outside of the circumference of the garage door motor shaft 1, and the upper part of the garage door motor shaft 1 is clamped through the semicircular slot 31 on the top of the head piece 3. The sprocket groove 32 is clamped to the sprocket 2 , and the chain groove 33 in the head piece 3 is used to place the chain moving with the metal sprocket piece 22 , thereby realizing the seamless connection between the head piece 3 and the sprocket 2 .

The preferred solution is that the outer two sides of the chain groove 33 are clamped in the C-shaped track 4, and the matching between the head piece 3 and the C-shaped track 4 is realized by clamping the outer two sides of the chain groove 33 in the C-shaped track 4 , the garage door motor is realized running on the C-shaped track 4 through the chain, and the cumbersome bolt connection is replaced by the clamping method, and the use strength is guaranteed at the same time.

Preferably, the material of the sprocket sleeve 21 and the head piece 3 is a mixture of nylon 6 and 30% glass fiber material, and the mixture has good heat aging resistance and oil resistance.
