Description

Belt shear brake block structure

This creation is related to the band shear, especially the brake pad structure of the band shear.

The figure shown in Fig. 6 is a conventional band cutter having two pivoting grips 71, 72, one of which has a brake block 73 pivoted thereon. The strap cutter is adapted to pass through a strap (not shown) of the loop bundle, wherein the strap is provided with an inverted tooth, and the brake block 73 is engaged with the inverted tooth of the strap and operated The two grips 71, 72 are pivoted back and forth to tension the strap to tighten the article, and then operate a grip 74 that controls the cutter 75 to cut the strap.

However, the conventional brake band 73 of the band cutter is used to form a blade-shaped blade for the card abutting portion 731 of the band, and the card abutting portion 731 is pressed against the band 8 as shown in FIG. The ground is pressed against the inverted tooth 81, and the band 8 has a similar cutting effect. If the thickness of the band 8 is thin, it is easily accidentally cut off, resulting in the band 8 being unable to continue to be used, resulting in waste. The production.

In view of this, how to improve the above problems is the primary issue that the creative office wants to solve.

The main purpose of the present invention is to provide a belt-scissor brake block structure, the front end of which is used to form a tooth-tooth shape against the card abutting portion of the belt, and the belt-shaped contact avoids cutting the belt to ensure the belt. The normal use of the scissors.

For the purpose of the foregoing, the present invention provides a belt shear brake block structure, comprising: a body; a pivoting portion disposed on the body for pivoting the body to the belt shear; The abutting portion is disposed at one end of the body, and the card abutting portion can be engaged with a belt controlled by the band shear with the pivoting of the body; the card abutting portion is formed by a plurality of teeth Row of teeth.

In one embodiment, the two outermost teeth of the teeth are respectively provided with a chamfered surface that is recessed toward the inner side.

The above objects and advantages of the present invention are not to be understood in detail from the detailed description and the accompanying drawings.

Please refer to FIG. 1 , which shows a bundle shear brake block structure provided by the present invention, comprising a block-shaped body 1 , which is provided with a pivoting portion 11 , thereby being pivoted on the belt clip, and the body is One of the ends is formed in a tip shape and is provided with a catching portion 12 for engaging with a band 6 controlled by the band shearing with the pivoting operation of the band shear. The card abutting portion 12 is provided with a tooth 13 composed of a plurality of teeth 131, 132. In the present embodiment, as shown in FIG. 2, two of the teeth are located at the outermost teeth 132. A chamfered surface 133 recessed toward the inner side is respectively provided, thereby preventing the teeth 132 on both sides from protruding toward the sides of the band cutter and injuring the user.

The band cutter matched with the present invention, as shown in Figs. 1 and 3, includes a first grip 2, a second grip 3, a grip 4 and a cutter 5, and the cut strap is cut. 6 has a reverse tooth 61 on one side, wherein the first grip 2 and the second grip 3 are pivotally connected by a shaft member 21, and the first grip 2 has a bottom plate 22 at the front end, and the bottom plate 22 is available The band 6 passes through the through hole 221, and the brake block of the present invention is pivoted with the pivoting portion 11 at the front end of the second grip 3, and the card abutting portion 12 is engaged with the inverted tooth 61 of the band 6. .

As shown in FIG. 4, the latching portion 12 is engaged with the teeth 61 of the strap 6 by the teeth 13 , and the teeth of the teeth 13 are in point contact with the strap 6 . Since the contact area is small, the contact pressure is increased, whereby a strong carding effect can be obtained; on the other hand, each tooth in the tooth 13 is only in contact with the band 6 in a point shape, and the band is not attached. 6 produces a cutting effect, which can effectively avoid the situation in which the band 6 is accidentally cut.

Furthermore, as shown in FIG. 3, at least one limiting member 23 is disposed on the first gripping member 2 adjacent to the bottom plate 22. A spacing D is formed between the limiting member 23 and the bottom plate 22, and the width thereof corresponds to the cutting blade 5 The thickness of the cutter 5 is set on the bottom plate 22 and just through the spacing D, the cutting belt grip 4 is pivotally connected to the first grip 2 by the shaft member 41 and connected to the cutter 5, so that the cutter 5 can be subjected to the cutter 5 The strap grip 4 is interlocked and is restrained by the stopper 23 to be attached to the bottom plate 22 for movement. In this embodiment, the limiting member 23 is two rods which are respectively disposed laterally on the first grip 2 with respect to the bottom plate 22.

In the present embodiment, the second grip 3 is provided with a notch 31. The rear end of the cutter 5 is provided with a barb-shaped bent portion 51 corresponding to the notch 31, and the pusher grip 4 is provided with a push rod 42. It passes through the notch 31 and the bent portion 51. With the above configuration, when the gripping belt grip 4 is pivoted, as shown in FIG. 5, the push rod 42 is driven to move in the notch 31, and the bending portion 51 is pushed to move the cutter 5, thereby The strap 6 is cut.

Through the above description, it can be found that the advantage of the present invention is that during the operation of the belt shearing, the teeth 13 are contacted with the belts 6 in a point shape, so that the pressure of the card is increased and the card can be firmly stuck. The strap 6 further smoothly pushes the strap 6 to tighten the object; on the other hand, the point contact of the tooth 13 and the strap 6 avoids the cutting effect on the strap 6, and the strap 6 can be effectively avoided. In the case of accidental cutting, the normal use of the band shear is maintained.

However, the above description of the embodiments is merely illustrative of the present invention and is not intended to limit the present invention. Therefore, the replacement of equivalent elements should still be within the scope of the present invention.

In summary, it can be made clear to the skilled person that the creation can achieve the aforementioned objectives, and it has already met the requirements of the Patent Law and submitted an application according to law.
