Description

Buckle pliers

This creation relates to the field of installation and removal of C-shaped buckles, and in particular to a buckle clamp.

The C-shaped buckle, also known as the circlip, is mostly used for fixing the shaft or the bearing or fixing the bearing in the hole. Therefore, the circlip is used for both internal and external applications and is used in the vehicle manufacturing and machinery industries.

The buckle clamp is also called a circlip pliers, and the inner circlip can be compressed to make the diameter smaller, and then the inner circlip is placed in the hole. Of course, the buckle clamp can also expand the diameter of the outer circlip and allow the outer circlip to be mounted on the drive shaft.

As shown in FIG. 5, the conventional buckle pliers 10 has a shaft 12 that pivotally couples a first caliper arm 20 to a second caliper arm 30. Centering on the shaft 12, the first caliper arm 20 and the second caliper arm 30 can reciprocate between the close and open positions, and the first caliper arm 20 and the second caliper arm 30 are restored to the original state through a spring 16. .

The shaft 12 is selected from one of the group consisting of screws and bolts. The shaft 12 passes through a reed 14, the first caliper arm 20 and locks the second caliper arm 30, allowing the first caliper arm 20 to rotate relative to the second caliper arm 30. In addition, the kinetic energy of the first caliper arm 20 and the second caliper arm 30 is absorbed by the reed 14 to prevent the shaft 12 from being disengaged from the second caliper arm 30 due to vibration.

The first caliper arm 20 has a first insertion section 22 and a first grip Department 24. The first insertion section 22 is straight and is located at a different end of the first jaw arm 20 from the first grip portion 24.

The second caliper arm 30 has a second insertion portion 32 and a second grip portion 34. The second insertion section 32 is also straight and is located at a different end of the second caliper arm 30 from the second grip 34.

As shown in FIGS. 6 and 7, the second caliper arm 30 further has a first screw hole 36 and a second screw hole 38. The shaft 12 passes through the first caliper arm 20 and locks the first screw hole 36 of the second caliper arm 30, so that the first caliper arm 20 is superposed on the second caliper arm 30. In the closed position, the first insertion segments 22 are substantially parallel and side by side to the right of the second insertion segment 32.

As shown in FIGS. 7 and 8, the shaft 12 passes through the first caliper arm 20 and locks the second screw hole 38 of the second caliper arm 30, so that the first caliper arm 20 is also stacked on the second caliper arm 30. In the closed position, the first insertion segments 22 are substantially parallel and side by side to the left of the second insertion segment 32.

In other words, when the buckle clamp 10 is in the close position, the first insertion section 22 and the second insertion section 32 are separated from each other by a fixed distance, which is defined as the minimum use distance of the buckle clamp 10. If the minimum use distance of the buckle clamp 10 is smaller than the spacing between the two ends of the circlip or the C-shaped buckle, the buckle clamp 10 can perform the setting operation with a circlip or a C-shaped buckle. However, the minimum use distance of the buckle clamp 10 is greater than the distance between the two ends of the circlip or the C-type buckle, and the buckle tong 10 cannot be inserted into the circlip or the C-type buckle, and of course, the inlay operation cannot be performed.

Therefore, how to make the buckle clamp apply more circlips or C-type buckles, which has become an urgent problem to be solved in this creation.

In view of this, this creation provides new buckle pliers, the main purpose is to use a slanted configuration, allowing the buckle pliers to apply more circlips or C-rings.

Due to the above objectives, the buckle of this creation includes: a first caliper arm having a first insertion section, the first insertion section being oblique; a second caliper arm having a second insertion section, the second insertion section being oblique; and a shaft passing through the shaft The first caliper arm is coupled to the second caliper arm, centered on the shaft, and the second caliper arm reciprocates in a closed position and an open position.

Wherein, the first caliper arm and the first insertion section have an angle therebetween. There is also an angle between the second caliper arm and the second insertion section. Each angle is in the range of 120° to 170°.

Of course, the second clamp arm has a first screw hole and a second screw hole. When the shaft passes through the first caliper arm and locks the first screw hole of the second caliper arm, the first insertion section is close to the second insertion section, and the front ends of the two are separated by a distance smaller than the distance between the roots. When the shaft passes through the first caliper arm and locks the second screw hole of the second caliper arm, the distance between the first insertion section and the root of the second insertion section is less than the distance separating the front ends.

Briefly, in the close position, the front ends of the first insertion section and the second insertion section face each other or opposite each other.

In particular, the front end of the first insertion section and the second insertion section are reduced in the minimum use distance, and of course, more circlips or C-type buckles are applied than the conventional buckle clamps.

Then, based on the detailed description of the related embodiments, the techniques, means and functions employed are described. It is believed that the above objects, structures and features of the present invention can be obtained from a deep and specific understanding.

Figures 6-8 show the continuous motion diagram of the conventional buckle clamp assembly.

In the first and second figures, the buckle pliers 10 also pivotally connects the first caliper arm 20 and the second caliper arm 30 with the shaft 12.

In this embodiment, the shaft 12 is selected from one of a group consisting of a screw and a bolt, which passes through the reed 14, the first caliper arm 20 and locks the first screw hole of the second caliper arm 30, allowing the first caliper arm 20 rotates relative to the second caliper arm 30.

Centering on the shaft 12, the first caliper arm 20 and the second caliper arm 30 are reciprocated between a closed position and an open position. Moreover, the kinetic energy of the first caliper arm 20 and the second caliper arm 30 is absorbed by the reed 14 to prevent the shaft 12 from being disengaged from the second caliper arm 30 due to vibration.

The first caliper arm 20 has a first insertion section 22 and a first grip portion, the first insertion section 22 being slanted at a different end of the first caliper arm 20 from the first grip. A imaginary line passing through the front end and the root of the first insertion section 22 is drawn, and an imaginary line passing through the end of the first caliper arm 20 is staggered so that an angle θ is sandwiched between the first caliper arm 20 and the first insertion section 22. The angle θ is in the range of 120° to 170°.

Similarly, the second caliper arm 30 has a second insertion section 32 and a second grip portion, which is also oblique, which is at a different end from the second grip portion 30 than the second grip portion. The imaginary line passes through the front end and the root of the second insertion section 32, and maintains an interlaced state with the b imaginary line passing through the end of the second caliper arm 30, so that the angle between the second caliper arm 30 and the second insertion section 32 is θ . The angle θ is in the range of 120° to 170°.

As shown in FIG. 1, the shaft 12 passes through the first caliper arm 20 and locks the first screw hole of the second caliper arm 30. In the closed position, the distance between the first insertion section 22 and the front end of the second insertion section 32 is less than the distance separating the roots.

In other words, the front ends of the first insertion section 22 and the second insertion section 32 face each other, reducing the minimum use distance of the buckle clamp, and is suitable for more circlips or C-type buckles.

As shown in FIG. 2, the shaft passes through the first caliper arm 20 and locks the second screw hole of the second caliper arm 30. In the closed position, the distance between the first insertion section 22 and the root of the second insertion section 32 is less than the distance H between the front ends. Briefly, the front ends of the first insertion section 22 and the second insertion section 32 are opposite to each other.

In Fig. 3, the first insertion section 22 of the first caliper arm 20 is embossed to form a plurality of lines 40. When the first insertion section 22 is inserted into the circlip or the C-shaped buckle, the circlip 40 prevents the circlip or the C-shaped buckle from leaving the first insertion section 22.

In Fig. 4, the second insertion section 32 of the second caliper arm 30 is formed with a concave-convex structure 42 to prevent the circlip or C-type buckle from leaving the second insertion section 32.
