Description

Technical Field

[0001] The utility model relates to the field of hardware tools, in particular to a portable large-torque manual mechanical knob. Background Art

[0002] Nowadays, mechanical structures are widely used in life, especially linear motion devices based on screws and rotary motion devices based on worm gears are widely used in many fields. In various fields, these devices usually use the rotation of motors to drive the mechanical parts to move, and finally achieve the required movement. During the design process, designers usually reserve mechanical interfaces to ensure that when electrical failures occur or manual debugging is required, debugging can be performed through the reserved mechanical interfaces. Most devices have high performance and large specifications, so a certain amount of external force is required to realize the operation of the mechanism. In response to this situation, designers usually use hand-cranked devices in the form of cranks or manual knobs in conjunction with mechanical interfaces to achieve work needs.

[0003] Existing crank devices need to be of a certain length, occupy a large space, and are not very convenient to carry. They need a certain amount of space to be used normally during use and carrying. Especially in special occasions, due to space limitations, it is impossible to reserve sufficient space for the crank to be used, so when manual debugging is required, the device cannot be manually debugged according to the operating manual.

[0004] Some small manual knobs are only suitable for use on small equipment. When used on equipment with larger specifications or longer strokes, the operator's hand cannot provide sufficient torque due to the small diameter of the knob, or the operator's hand becomes uncomfortable after manually rotating a certain angle and cannot continue to work normally.

[0005] Therefore, it is of great significance to design a portable large-torque manual mechanical knob device. Utility Model Content

[0006] The utility model aims to provide a portable large torque manual mechanical knob, which comprises a knob and a protrusion.

[0007] The top surface of the knob is provided with a protrusion.

[0008] The shape of the protrusion is adapted to the shape of the reserved interface at the input end of the device.

[0009] The bottom surface of the knob is provided with a groove.

[0010] The side wall of the groove is provided with an internal thread which matches the external thread reserved at the input end of the device.

[0011] Further, the protrusion is arranged at the center of the top surface of the knob.

[0012] Furthermore, the bottom height of the knob is higher than the input terminal height of the device.

[0013] Furthermore, the outer side wall of the knob is provided with vertical stripes or knurling.

[0014] Furthermore, when not in use, the manual mechanical knob is connected to the external thread reserved at the input end of the device through the internal thread of the groove side wall.

[0015] Furthermore, in the debugging state, the protrusion of the manual mechanical knob is located in the reserved interface of the device input terminal.

[0016] Furthermore, inside the knob, a connecting groove is provided at the exact center of the bottom surface of the groove; the notch of the connecting groove is connected to the bottom of the groove, and the bottom of the connecting groove is close to the protrusion.

[0017] Furthermore, the length and width of the connecting groove are both smaller than the diameter of the groove.

[0018] Furthermore, the shape of the connecting groove matches the specification of the ratchet wrench.

[0019] Furthermore, when a torque greater than 20 N·m is required, the protrusion (2) of the manual mechanical knob is located in a reserved interface at the input end of the device, and the ratchet wrench is inserted into the connection slot.

[0020] The technical effect of the utility model is unquestionable, and the beneficial effects of the utility model are as follows:

[0021] 1. The manual mechanical knob of the utility model overcomes the problems that the existing manual crank is too large in size, requires sufficient operating space or the manual knob has insufficient torque and is only suitable for small and short-stroke equipment.

[0022] 2. The manual mechanical knob of the utility model can be directly installed on the product and does not need to be packaged separately.

[0023] 3. The manual mechanical knob designed in the utility model can conveniently realize the manual debugging function of the linear motion device with the screw as the core or the N×360° rotating device with the worm gear as the core. BRIEF DESCRIPTION OF THE DRAWINGS
