Description

Operating handle

[Technical Field]

The present invention relates to an operating handle and, more particularly, to an operating handle that is pulled by magnetic force. 【Background technique】

Conventional operation levers using magnetic traction generally have magnetic blocks on the side of the operating device, which slide directly on the surface of the non-magnetically conductive medium. Because of the large frictional force, the operation force is large, the control precision is not easy to grasp, and the operation is not very good. Convenient, and sliding directly on the contact surface is also easy to scratch the surface. There is an operating handle with a common roller on the market, which can be directly rolled on the contact surface, which is convenient to operate. However, when the power on the operating device in the direction of the contact surface is cancelled, if the gravity of the operating device is in the horizontal direction along the contact surface, Then the friction between the circular roller and the contact surface is not enough to stop the operation device, and an additional limit mechanism needs to be added; even if the operation device is placed horizontally, slight touch and vibration are easy to slide, and the limit effect is not ideal.

Preferably, the distance between the rotating shaft and the center of the circle is between 0.05 mm and 0.5 mm, so that At the same time as the barrier is reliable, a better feel is obtained.

Preferably, the distance from the center of the rotating shaft to the center of the circle is between 0.1 mm and 0.3 mm, which provides a more preferable range of values, and a better hand feel while ensuring a reliable limit.

Preferably, the roller wheel surface has a plane, and the planes are connected by an outwardly curved arc surface.

The utility model adopts a roller with a resistance position, and the contact position between the roller and the non-magnetic medium is automatically formed at a position closest to the axis where the rotating shaft is located, and the power on the operating handle is cancelled when the roller is in the position. If the non-magnetic medium is horizontal, when the handle is subjected to a slight horizontal thrust, the roller resistance position is deviated from the contact surface, and the roller and the magnetic force of the vertical contact surface pull the roller back to the resistance position. The operating handle remains stationary; if the non-magnetically conductive medium is tilted, the horizontal component of gravity generated on the surface of the parallel non-magnetically conductive medium drives the roller to continue to rotate, but the pressure and magnetic force generated by the gravity on the surface of the vertical non-magnetically conductive medium are superimposed. When the resistance position deviates from the contact surface, the stress will be generated in the opposite direction to the horizontal component of gravity. Together with the friction between the roller and the contact surface, the static state of the operating handle can be maintained as long as the magnetic force is properly configured. The medium is vertical, and the magnetic force will be produced when the resistance is off the contact surface. The opposite of the gravity of the operating handle With force, plus the friction of the roller and the contact surface, the static state of the operating handle can be maintained as long as the magnetic force is properly configured.

【detailed description】

The invention will now be further described with reference to the drawings and preferred embodiments.

As shown in Fig. 1, an operating handle includes an operating device 1. A pulling device 5 opposed to the operating device 1, and a non-magnetic conductive medium 6 interposed between the operating device 1 and the pulling device 5. At least one of the operating device and the traction device includes a first support 21 structure. The first support structure 21 is fixed with a first rotating shaft 71. The first rotating shaft 71 is mounted with a first roller 31. The first roller 31 is in a At least one of the contact positions with the non-magnetically conductive medium 6 is closest to the first rotating shaft 71 during the rotation period. The first support structure 21 may be any other structural form in which the metal housing, the handle or the like can support the first roller 31. The operating device 1 and the traction device 5 are connected by magnetic force, so that at least one of the first magnetic materials 41 such as magnets and magnets is provided between the two. The first magnetic material 41 may be disposed at one or more locations of the first support structure 21 and the first roller 31.

The second rotating shaft 72 is mounted with a second roller 32. The second roller 32 has at least one contact position with the non-magnetically conductive medium 6 closest to the second rotating shaft 72 during one rotation period. The second support structure 22 can be any other form of metal housing, handle or the like that can support the second roller 32. The operating device 1 and the traction device 5 are connected by magnetic force, so that at least one of the two is provided with a second magnetic material 42 such as a magnet or a magnet. The second magnetic material 42 may be disposed at one or more of the first support structure 21, the second support structure 22, the first roller 31, and the second roller 32.

As shown in FIGS. 2-6, the first roller 31 and the second roller 32 are rollers with a resistance position, and the contact position of the roller with the non-magnetic medium 6 is the closest to the axis 9 where the rotating shaft is located. When the roller is in this position, the power on the operating handle is cancelled. At this time, if the non-magnetic medium 6 is horizontal, when the handle is subjected to a slight horizontal thrust, the roller resistance position is deviated from the contact surface, and the vertical contact is made. Under the action of gravity and magnetic force, the roller will be pulled back to the resistance position, so that the operating handle remains stationary; if the non-magnetically conductive medium 6 is inclined, the horizontal component force generated by gravity on the surface of the parallel non-magnetically conductive medium 6 drives the roller to continue. Rotation, but the pressure and magnetic force generated by gravity on the surface of the vertical non-magnetically conductive medium 6 are superimposed. When the resistance position deviates from the contact surface, a stress opposite to the horizontal component of gravity is generated, and the friction between the roller and the contact surface is generated. Force, as long as the magnetic force is properly configured, the static state of the operating handle can be maintained; if the non-magnetically conductive medium 6 is vertical, then the magnetic When the force is deviated from the contact surface at the resistance position, the force opposite to the operating handle is generated.

The distance between the axis 9 and the center of the circle ranges from 0.05 mm to 0.5 mm. Preferably, the distance Between 0.1mm~0.3mm, within this range, a better hand can be obtained while ensuring the limit effect.

The vertical distance of the axis 9 from the plane is smaller than the distance of the axis 9 from the arc surface. Therefore, when the respective planes of the roller are in contact with the contact surface, the distance between the operating device 1 and the traction device 5 is the closest, and the magnetic force is the strongest, and the position is the resistance. position. The roller can have multiple resistance positions, and the control precision is further improved. In addition, the non-resistance position is a curved surface, and the rolling process is smooth and the hand feel is good.
