Description

Rotating impact component structure improvement

This creation is about a "rotational impact component structure improvement", especially a component that is used in an impact tool (such as an impact wrench) to increase the rotational inertia to quickly loosen or tighten the lock. .

According to the conventional impact wrench, it is mainly used for loosening or tightening the screw lock. The common manual impact wrench, such as Taiwan Patent Publication No. M400389, is a manual impact wrench structure, which is formed with two pivots at one end of the body. A pivoting sleeve having a hollow cylindrical structure is disposed between the ears. The pivoting kit is provided with a spring and a reversing member. One end of the reversing member is received in the pivoting sleeve and abuts against the spring, and the other end is convexly formed with a driving. a reversing portion is formed on each of the two sides of the reversing member, and each of the reversing portions has a forward groove and a reverse groove with opposite slopes, and the forward groove and the reverse groove are connected by a turning groove to be positioned by two The column is respectively provided with a pivot ear, a pivot sleeve and a reversing member, and the end of the positioning post is accommodated in the reversing portion of the reversing member.

The above-mentioned conventional structure mainly uses a driving head to be engaged with a tool member such as a sleeve, and applies an external force to a hammering surface of the pivoting kit by a hand tool such as a hammer, and the tool member that is engaged with the driving head passes through the tool. Instantly displace the force to achieve the purpose of loosening or tightening the screw.

However, the components are complicated, and the user needs to use the hammer to forcefully hit the hammer surface of the pivot kit, which is not only troublesome, but also inconvenient in operation and at the same time, because each tap is performed once. The torque value is very small and fixed, so it takes a lot of time to loosen or tighten the screw lock; therefore, the various shortcomings of the above-mentioned conventional ones are necessary for further improvement.

In view of the fact that there are still some improvements in the current structure, the creator has been engaged in the multi-year production and sales experience of related products, and has been thinking about the existing problems and pondering the improvement methods. After many improvements and tests, the author finally created a kind of rotation. The structure of the impact component is improved.

Therefore, the main purpose of the present invention is to provide a structure for improving the rotational inertia and the amount of torque to quickly loosen or fasten the fastener, and the operation mode is simple and convenient.

Another object of the present invention is to provide a rotary impact assembly that can be combined with a plurality of specifications of the adapter sleeve, which is not only convenient for replacement but also can effectively reduce the purchase cost.

In order to achieve the above object, the present invention proposes a structural improvement of a rotary impact assembly which is composed of a rotary tool and a rotary impact assembly, the rotary tool being assembled with the rotary impact assembly to enable the rotary impact assembly to be rotated. The tool is activated and rotated; the improvement is that the rotary impact assembly has a weight plate, and the two sides of the weight plate have a first surface and a second surface, respectively, and a jack is disposed in the center of the first surface The socket has a plug portion at the center of the second surface.

Wherein, the first and second surface setting positions of the weight plate respectively have a circular ring-shaped recess.

Wherein, the weight plate has a plurality of through holes.

Wherein, the socket setting position of the weight plate has a positioning component.

Wherein, the insertion portion of the weight plate has a positioning component.

Wherein, the positioning component is composed of a spring and a steel ball.

Wherein, the rotating tool is a pneumatic tool or a power tool.

The following description of the preferred embodiment of the present invention is further described below in order to enable those skilled in the art to practice the present invention to be implemented in accordance with the present specification.

The second picture is a three-dimensional appearance of the creation.

The third picture is a schematic cross-section of the creation.

The fourth drawing is a schematic perspective view of another embodiment of the present creation.

The fifth drawing is a side view of another embodiment of the present creation.

First, please refer to the first to fifth figures. The present invention is a structural improvement of a rotary impact assembly, which is composed of a rotary tool 10 and a rotary impact assembly A, and the rotary tool 10 is capable of with the rotary impact. The assembly A is assembled so that the rotary impact assembly A can be rotated by the rotary tool 10; and it is worth noting that the rotary impact assembly A has a counterweight disk 20, and each side of the weight plate 20 has a The first surface 21 and the second surface 22 are disposed at the center of the first surface 21 with a socket portion 23 having a socket 231. The second surface 22 has a plug portion 24 at the center.

The first and second surfaces 21 and 22 of the weight plate 20 have a circular ring-shaped recess 25 respectively.

The weight plate 20 has a plurality of through holes 26 .

The sleeve portion 23 of the weight plate 20 has a positioning component (not shown) at a set position.

The insertion portion 24 of the weight plate 20 has a positioning component (not shown) at a set position.

Wherein, the positioning component is composed of a spring and a steel ball (not shown).

Wherein, the rotating tool 10 is a pneumatic tool or a power tool.

With the above combination, please refer to the first to fifth figures. When the user wants to use this creation to loosen or tighten the fasteners (not shown), first of all, only The operating portion 11 of the rotary tool 10 is mounted on the socket portion 23 or the plug portion 24 of the weight plate 20, wherein when the operating portion 11 is a male card, it is inserted into the socket portion 23, and if When the portion 11 is a female kit, it is sleeved in the insertion portion 24; in the embodiment, the operation portion 11 of the rotary tool 10 is a male insert.

Thereafter, an adapter sleeve 30 (shown in the first figure) is additionally disposed on the insertion portion 24 of the weight plate 20, and the user can assemble the other end of the adapter sleeve 30 to the fastener ( In the figure, the user can activate the rotary tool 10, which can be a pneumatic tool or a power tool, to rotate the operating portion 11 of the rotary tool 10, and synchronously rotate the counterweight disk 20 to make the adapter sleeve. The cylinder 30 can increase the amount of torque applied to the fastener by utilizing the increased rotational inertia of the weight plate 20 to quickly loosen or fasten the fastener, and the overall operation mode is simple and convenient, and has practical utility.

It should be noted that, in this embodiment, since the diameter of the weight plate 20 is larger than the diameter of the adapter sleeve 30, the inertial gravitational acceleration is based on the weight plate 20, and is loosened or rotated. When the fastener is tightened, the torque or rotational speed of the rotary tool 10 will increase its torque or rotational speed by a multiple of the diameter of the counterweight disk 20 and the adapter sleeve 30.

In addition, since the weight plate 20 of the present invention can be matched with the size of the sleeve of the plurality of specifications of the adapter sleeve 30, it is not only convenient to use, but also can effectively reduce the purchase cost and is practical.

In summary, the structure of the rotary impact component is improved, and the various shortcomings of the conventional structure are effectively improved, and the main technical means of the creation are not found in any related publications, and the application requirements of the new patent are met. To file an application, the Department of Health is requested to grant the patent right.
