Description

Transmission kit for wrench tools

The invention relates to a transmission kit of a wrench tool, in particular to a wrench tool transmission kit that can facilitate the operation of the wrench tool in a narrow space.

General wrench tools can be divided into pneumatic wrench tools and manual wrench tools. The conventional pneumatic wrench tool has a drive mechanism inside, which can drive the drive shaft protruding from the front end of the pneumatic tool to drive the sleeve sleeved on the drive shaft to rotate, thereby locking or unscrewing the locked bolt or nut through the sleeve . The conventional manual wrench tool is provided with a sleeve or opening at one end of the long grip. After the bolt or nut to be locked or unscrewed is sleeved through the sleeve or opening, the long grip can be used The principle of leverage turns a bolt or nut. In order to make the use of the conventional manual wrench tool more convenient, there is a socket wrench which can be used as an improvement. The conventional socket wrench has a joint on one end of the long handle, which can be used to socket various sockets. The socket is used to socket the bolt or nut to be locked or unscrewed, and the socket is swung. The long handle of the barrel wrench can be used to turn the bolt or nut.

Especially when there is no sufficient space above the locked bolt or nut, and the operator cannot place the pneumatic wrench tool above the bolt or nut, the operator will not be able to use the pneumatic wrench tool for work. The conventional manual wrench tools, including socket wrenches, require enough working space after socketing bolts or nuts, so that the operator can socket with sockets. The bolt or nut is the shaft center, and the long grip is used to form a lever swing to rotate the bolt or nut. When there is not enough working space around the bolt or nut, it will be difficult for the operator to drive the bolt or nut to rotate through the manual wrench tool. In view of this, after observing the above-mentioned shortcomings, the inventor of the present case believes that there is a need for further improvement of the conventional wrench tool, and thus the present invention was born.

The purpose of the present invention is to provide a transmission kit for a wrench tool, which can be smoothly used in a narrow space that is not enough to accommodate a pneumatic tool or a narrow space that is difficult to operate with a hand tool through a simple socket Work on it.

The driving shaft 210 of the pneumatic tool 200 drives the driving unit 20 through the socket hole 22, and drives the transmission unit 40 to rotate through the driving wheel 23 of the driving unit 20, and then further drives the driving unit 40 to engage with it through the transmission unit 40 The driven unit 30 rotates. In this way, the driven unit 30 can drive the bolt 300 to rotate, thereby completing the operation of locking or unscrewing the bolt 300. However, this is only an embodiment and does not limit the implementation of the present invention. The driven unit 30 can also be sleeved with a nut and locked or unscrewed.

When the present invention is assembled with a manual wrench tool, it is basically the same as the method of assembling a pneumatic wrench tool. It only requires a simple socketing action. Please refer to Fig. 2 again to coordinate the cover of the active unit 20. The socket 22 is sleeved on the socket of the socket wrench, and the clamping part 221 The joint of the socket wrench is clamped and fixed to the socket hole 22, and the assembly of the hand tool and the transmission kit can be easily completed.

Therefore, the present invention can easily complete the assembly with pneumatic tools or hand tools through simple sockets, allowing the operator to use wrench tools to work in a small space without having to prepare for the small working space encountered by chance Other dedicated tools.

It is worth mentioning that the driving unit 20 and its surrounding driving wheel 23, the driven unit 30 and its surrounding driven wheel 33, and the gears in the gear set of the transmission unit 40 are all integrally formed, so There is no gap when it rotates, and the accuracy of its assembly can be increased. In addition, it can have a higher structural strength and is not easy to be damaged, and it is not easy to generate noise during operation.

In addition, the gear train of the transmission unit 40 allows the driven unit 30 and the driving unit 20 to rotate in the same direction, so that the operator can use the transmission kit to work more intuitively. In the first embodiment of the present invention, the gear set is connected between the driving unit 20 and the driven unit 30 by pivoting an odd number of gears so that the driven unit 30 and the driving unit 20 can rotate in the same direction.

Please refer to FIG. 4 again, which discloses the second embodiment of the present invention. The main structure of the second embodiment of the present invention is the same as that of the aforementioned first embodiment of the present invention, so it will not be repeated. The main difference is that this embodiment is provided with an adjusting sleeve 34 in the polygonal hole 32 of the driven unit 30, and the outer diameter of the adjusting sleeve 34 matches the inner diameter of the polygonal hole 32, so that the The adjusting sleeve 34 can be assembled with the polygonal hole 32 through a socketing method, and clamped and fixed in the polygonal hole 32, and a polygonal hole is also formed in the adjusting sleeve 34, and the polygonal hole of the adjusting sleeve 34 and The polygonal holes 32 of the driven unit 30 have the same shape but different inner diameters. Thereby, the transmission kit can be fitted with the adjusting sleeve 34 to sleeve bolts or nuts of different sizes, so that the transmission kit can be applied to bolts or nuts of different sizes.

Please refer to Figure 5 again, which discloses a third embodiment of the present invention. The difference from the aforementioned first embodiment of the present invention is that the sleeve body 50 is provided with a bent portion 52 to form an included angle, and The bending portion 52 is located between the driving unit 60 and the driven unit 70 so that the first axis A′ of the driving unit 60 and the second axis B′ of the driven unit 70 are non-parallel. Wherein, the transmission unit 80 is pivotally provided with a fifth gear 83 at the bending portion 52, and the fifth gear 83 is a bevel gear, that is, the fifth gear 831 circumferentially arranged on the peripheral side of the fifth gear 83 is The helical teeth enable the transmission unit 80 to be bent at the bending portion 52 through the fifth gear 83.

In detail, in the third embodiment of the present invention, the driving wheel 63 of the driving unit 60 is engaged with the third tooth 811 of the third gear 81, and the third gear 81 passes through the third tooth on the other side. The portion 811 meshes with the fifth tooth portion 831 of the fifth gear 83. Since the fifth tooth 831 is a helical tooth, the fifth gear 83 and the third gear 81 will form a bending angle at the meshing position. The fifth gear 83 meshes with the fourth gear 82 on the opposite side of the third gear 81, so that the fifth gear 831 of the fifth gear 83 can mesh with the fourth gear 821 of the fourth gear 82. The fifth gear 83 and the fourth gear 82 also form a bending angle because the fifth tooth 831 is a helical tooth. The fourth gear 82 passes through the fourth tooth portion 821 on the other side of the fourth gear 82 to engage the driven wheel 73 of the driven unit 70 again.

Thereby, the fifth gear 83 can rotate through the conical pitch surface of the bevel gear to transmit the torque of the third gear 81 that is intersected with it, and then further transmit to the fourth gear 82, so that the driving unit 60 The transmission unit 80 can drive the driven unit 70 to rotate. And because an umbrella-shaped fifth gear 83 is pivoted between the third gear 81 and the fourth gear 82, and a bending angle can be formed at the meshing position, the transmission unit 80 can be attached to the fifth gear 83. A bend is formed so that the transmission unit 80 is bent in accordance with the bending portion 52 of the sleeve body 50. The operator can easily use the transmission kit to extend into the narrow and tortuous working space to perform operations through the transmission kit with the bending portion 52.

Hereinafter, the characteristics of the present invention and the expected effects that can be achieved are described as follows: The transmission kit for the wrench tool of the present invention can be combined with the wrench tool through a simple socket action. When the wrench tool is sleeved on the transmission kit, it can extend into the narrow working space through the transmission kit, and lock or unscrew the bolts or nuts in the narrow space through the driven unit, so that the operator can easily work in the narrow space Use the wrench tool for work.

In summary, the present invention has excellent practicality in similar products. At the same time, we have checked the domestic and foreign technical information about this type of structure. The literature has not found the same structure. Therefore, The present invention actually has the requirements for a patent for invention, and an application is filed according to law.

However, the above is only one of the preferred and feasible embodiments of the present invention. Therefore, any equivalent structural changes made by applying the specification of the present invention and the scope of the patent application should be included in the patent scope of the present invention.
