Detailed Description

The invention will be further described in the following with reference to specific embodiments thereof,

as shown in fig. 5 to 6, in the conventional fastener tape transmitting clip, the second movable ends 35 of the upper and

lower clips

31 and 32 are not directly connected to the push rod 5, and the conventional push rod 5 is tapered, so that when a force is applied to the second movable ends 35 of the upper and

lower clips

31 and 32, the force applied to the second movable ends 35 by the tapered push rod 5 is always perpendicular to the tapered surface of the push rod 5 regardless of the change in the rotation angle of the upper and

lower clips

31 and 32. Therefore, although the upper clip half 31 and the lower clip half 32 are closed, the force of the engagement between the two is not so large, and the tape may be detached from the clip 3 during the tape pulling process.

As shown in fig. 1-3, in the chain belt transmission clip of the present invention, the overall structure is substantially the same as that of the existing chain belt transmission clip, including a clip base 1, a cylinder 2 and a clip 3, the clip 3 is also divided into an upper clip 31 and a lower clip 32, the upper clip 31 and the lower clip 32 each include a rotating portion 33, a first movable end 34 and a rotating portion 33 of a second movable end 35 fixed on the clip base 1 through a connecting component such as a pin, a push rod 5 is connected on a piston rod of the cylinder 2, a connecting rod 4 is hinged on the second movable end 35 of the upper clip 31 and the lower clip 32, the connecting rod 4 is also fixed on the second movable end 35 through a connecting component such as a pin, the front end of the push rod 5 draws together the connecting rods 4 on the upper clip 31 and the lower clip 32, and the three are hinged, when the push rod 5 moves forwards or backwards, the two sections of the connecting rod 4 are driven to move together, according to the actual test results, when the push rod 5 is pushed forward, the action angle between the connecting rod 4 and the second movable end 35 becomes larger, that is, the angle between the connecting rod 4 and the horizontal axis becomes smaller as shown in fig. 3, so that the force applied to the second movable end 35 by the connecting rod 4 becomes very large, and the engaging force of the first movable end 34 of the upper half clamp 31 and the lower half clamp 32 becomes very large, and the chain belt engaged therein is not easily disengaged therefrom.

Further, as shown in fig. 2-4, a push rod slide seat 6 is arranged in the clip seat 1, a slide groove 61 is arranged in the push rod slide seat 6, slide blocks 53 are arranged on two sides of the opposite push rod 5, the push rod 5 moves back and forth in the slide groove 61 of the push rod slide seat 6 under the action of the cylinder 2, and because the push rod 5 needs to apply an acting force to the connecting rod 4, the connecting rod 4 can apply a reaction force to the push rod 5, and in order to stabilize the movement of the push rod 5, the whole system tends to be stable, and the purpose is further achieved through the push rod slide seat 6.

Further, when the piston rod of the cylinder 2 is pushed to the maximum stroke, the angle formed by the connecting rods 4 of the upper half clamp 31 and the lower half clamp 32 is less than 180 °. Since the angle formed between the two connecting rods 4 is 180 ° as a critical point, when the two connecting rods 4 are pushed forward, the angle between the two connecting rods 4 is gradually reduced, and the acting force on the second movable end 35 of the upper half clamp 31 and the lower half clamp 32 is lost, so that the stroke of the piston rod of the cylinder 2 needs to be limited, and when the stroke reaches the maximum value, the angle formed by the two connecting rods 4 needs to be less than 180 °, and therefore, the cylinder 2 used in the mechanism is also an adjustable cylinder.

As shown in fig. 2, the first movable ends 34 of the upper and

lower clips

31 and 32 are formed with a holding portion 36, and the holding portion 36 is provided with anti-slip teeth 37 to further enhance the friction force when the clip 3 clamps the fastener tape.

Further, when the grasping portions 36 of the upper and

lower clips

31 and 32 are engaged with each other, the portions of the upper and

lower clips

31 and 32 located between the grasping portions 36 and the rotating portion 33 are not in contact with each other. This is mainly designed to make the force applied when the upper clip half 31 and the lower clip half 32 are clamped to each other concentrate on the clamping portion 36, and to clamp the fastener tape more tightly without being dispersed to other portions.

Further, as shown in fig. 2 and 3, the distance from the first movable end 34 to the rotating portion 33 is greater than the distance from the second movable end 35 to the rotating portion 33. This design makes it possible to stabilize the force exerted by the push rod 5 when it is translated into the first movable end 34.

The above-mentioned embodiment is only the preferred embodiment of the present invention, and does not limit the protection scope of the present invention according to this, so: all equivalent changes made according to the structure, shape and principle of the utility model are covered within the protection scope of the utility model.
