Description

Technical Field

[0001] This utility model relates to the field of socket wrench technology, and in particular to a socket wrench for rapid operation. Background Technology

[0002] A socket wrench typically consists of a T-shaped rod and a socket head. The T-shaped rod can be connected to socket heads of different sizes to install and remove fasteners.

[0003] After loosening fasteners, socket wrenches need to be rotated several more times to remove them. However, controlling the rotation of the socket wrench several times is cumbersome, requiring the operator to hold the transverse handle inside the T-bar with both hands and rotate it one turn in the direction of the thread, which is time-consuming and laborious. To improve efficiency, the operator may hold the guide rod inside the T-bar with one hand and use the other hand to rotate the transverse handle. However, in this method, the palm of the hand holding the guide rod is prone to friction and heat, causing discomfort, and the socket wrench is prone to slipping. Furthermore, the transverse handle inside the T-bar can easily hit the operator's arm. Therefore, the existing socket wrench needs to be improved to make it easier to rotate quickly under low load.

For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection, an electrical connection, or a connection that allows communication between them; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components, unless otherwise explicitly limited. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0019] Reference Figures 1-4According to an embodiment of the present invention, a quick-operating socket wrench includes a guide rod 11. The lower end of the guide rod 11 is equipped with a mounting seat 12 for connecting a socket head. A spring ball can also be installed in the mounting seat 12 to increase the connection strength with the socket head. Of course, the lower end of the guide rod 11 can also be directly welded or integrally formed with a socket head. These are conventional settings in the prior art and will not be described in detail here.

[0020] In addition, such as Figure 2 and Figure 3 As shown, the upper end of the guide rod 11 is integrally formed with a turntable 13, and the upper side of the turntable 13 is provided with a drive column 14. It also includes a control component 15, which is used to control the rotation of the turntable 13 and the guide rod 11 to perform the rotation of the fastener.

[0021] Specifically, such as Figure 1-3 As shown, the control component 15 includes a disc body 21. The bottom surface of the disc body 21 has a circular groove 22 coaxially arranged with the disc body 21. The turntable 13 is rotatably connected to the circular groove 22, and the drive column 14 extends to the upper side of the disc body 21. The disc body 21 is provided with an acceleration drive assembly for driving the drive column 14 to rotate. In addition, two coaxial and oppositely distributed grip rods 23 are provided on the curved surface of the disc body 21. The curved surface of the circular groove 22 has a sliding hole 24 extending into the grip rod 23. A plug rod 25 is slidably connected in the sliding hole 24. The curved surface of the turntable 13 has a slot 26 for accommodating the plug rod 25. It also includes a clutch assembly for controlling the plug rod 25 to enter and exit the slot 26.

[0022] When the insertion rod 25 is inserted into the slot 26, the operator can rotate the handle 23 and then the insertion rod 25 to drive the turntable 13, the guide rod 11 and the mounting base 12 to rotate. This is suitable for operations that require large torque. When the insertion rod 25 leaves the slot 26, the worker can drive the drive column 14 to rotate through the acceleration drive assembly, which in turn drives the turntable 13 and the guide rod 11 to rotate quickly. This is suitable for fast operations that require less torque, i.e., for subsequent work after the bolts have been loosened.

[0023] In this embodiment, the acceleration drive assembly includes an eccentric disk 31 rotatably connected to the disk body 21. A gear ring 32 is provided inside the eccentric disk 31, and a gear meshing with the gear ring 32 is sleeved on the drive column 14. The gear ring 32 is not coaxial with the drive column 14.

[0024] In addition, a hand crank 33 is installed on the upper axis of the eccentric disk 31.

[0025] When the insertion rod 25 leaves the slot 26, the operator can use the hand crank 33 to drive the eccentric disk 31 and the gear ring 32 to rotate (the operator holds the handle 23 with one hand and drives the hand crank 33 to rotate with the other hand), thereby driving the drive column 14, the turntable 13 and the guide rod 11 to rotate rapidly.

[0026] In addition, such as Figure 4 As shown, the clutch assembly includes a sliding groove 41 disposed in the upper side of the sliding hole 24. A sliding plate 42 is slidably connected in the sliding groove 41. The sliding plate 42 extends downward into the sliding hole 24 and is inserted into the inclined groove 43 in the insert rod 25. The sides of the sliding plate 42 and the inclined groove 43 near the turntable 13 are both inclined surfaces that fit together. The insert rod 25 is also connected to the bottom surface of the sliding hole 24 by a return spring.

[0027] With the above configuration, when the operator presses the slide plate 42, the slide plate 42 will move downwards and push the insertion rod 25 inwards through the cooperation of the inclined surface. At this time, the insertion rod 25 can be inserted into the slot 26. Then, the rotation of the grip rod 23 and the disc body 21 can drive the guide rod 11 to rotate. When the slide plate 42 is no longer pressed, the return spring will drive the insertion rod 25 to return to its original position, causing the slide plate 42 to pop out. Furthermore, the upper side of the slide plate 42 is provided with a pressure plate 44, and the upper side of the pressure plate 44 is curved to facilitate user pressing.

[0028] With this design, the user can press the pressure plate 44 while holding the grip 23, which is convenient and requires no additional operation, reducing the learning cost. In order to make the movement of the pressure plate 14 stable, a guide rod is also provided at the edge of the pressure plate 14 to insert into the inner groove of the curved surface of the grip 23.

[0029] In the second embodiment of the fast-operating socket wrench, to prevent the downward pressing action of the pressure plate 44 from being hindered when the slot 26 is misaligned with the insert rod 25, the insert rod 25 is designed to consist of a pin rod 51 and a slotted rod 52. The inclined groove 43 is formed in the slotted rod 52, and the return spring is connected to the slotted rod 52. The end face of the pin rod 51 away from the turntable 13 is provided with a spring groove. One end of the slotted rod 52 is integrally formed with a small-diameter rod that is inserted into the spring groove, and the small-diameter rod is connected to the bottom surface of the spring groove through a compression spring.

[0030] With the above settings, even if the insertion rod 25 is misaligned in the slot 26, the insertion rod 25 will still be inserted into the slot 26 under the action of the compression spring during the rotation of the guide rod 11 and the turntable 13, so that the operator does not need to actively straighten it. In addition, the slot 26 is provided with four slots distributed at equal angles for easy operation.

[0031] The above description is only a specific embodiment of the present utility model, but the technical features of the present utility model are not limited thereto. Any changes or modifications made by those skilled in the art within the scope of the present utility model are covered by the patent scope of the present utility model.
