Technical Field

[0001] The invention relates to the technical field of rotary gyroscopic motion mechanisms, and in particular to a mechanism for converting linear reciprocating motion into gyroscopic motion. Background Art

[0002] There are many mechanical ways to convert linear motion into rotational motion, such as crank slider mechanism, ball screw mechanism, rack and pinion mechanism, etc., and the above structures all use the one-way work of the drive to realize the conversion of linear motion into rotational motion. Rotational motion can be used to control the device, among which the rotary control knob is commonly used to control a variety of devices. The control knob is installed to perform rotational motion and is manually rotated by the user to control the output of the device or input to the device.

[0003] However, when the existing rotary control buttons are used, the rotation angle cannot be accurately controlled and there is a problem of cumulative error.

[0004] In order to solve the above problems, the applicant has designed a mechanism that can convert both linear reciprocating motion into rotation in the same direction based on the existing transmission mechanical principles, and can control the angle of each rotation through a dividing mechanism, thus avoiding the cumulative error of multiple consecutive rotations in the same direction. Summary of the invention

[0005] The technical problem to be solved by the present invention is to overcome the defects of the above-mentioned technology and provide a mechanism for converting linear reciprocating motion into rotary motion, the purpose of which is to drive one-way gear one and one-way gear two to rotate respectively through relatively staggered racks one and two, and utilize their one-way rotation function to achieve the technical effect of driving the rotating shaft to rotate unidirectionally.

[0006] In order to solve the above technical problems, the technical solution provided by the present invention is as follows: a linear reciprocating motion conversion rotary motion mechanism, comprising a fixed frame, a moving rack frame linearly reciprocatingly slidably connected thereto is arranged in the fixed frame, a rotating shaft is arranged in the moving rack frame, the rotating shaft is rotatably connected to the fixed frame, and a one-way gear 1 and a one-way gear 2 are sleeved on the rotating shaft;

[0007] A rack 1 matched with a one-way gear 1 is arranged on one side of the movable rack frame, and a rack 2 matched with a one-way gear 2 is arranged on the other side of the movable rack frame.

[0008] Furthermore, one end of the rotating shaft extends out of the fixed frame and is connected to a dividing turntable, the outer ring of the dividing turntable is evenly provided with a plurality of sharp corners, and the front and rear of the movable rack frame are provided with limit blocks that cooperate with the sharp corners, and the limit blocks are two symmetrically arranged in an staggered manner.

[0009] Furthermore, the rack 1 and the rack 2 are arranged in an alternating manner relative to each other, and the one-way gear 1 and the one-way gear 2 have the same rotation direction.

[0010] Furthermore, a hole is provided at the bottom of the fixing frame, a connecting piece is slidably provided in the hole, one end of the connecting piece is fixedly connected to the movable rack frame, and the connecting piece is used to pull the movable rack frame to perform reciprocating linear motion.

[0011] The advantages of the present invention over the prior art are: the present invention realizes the technical effect of bidirectional driving of the rotating shaft by moving the rack frame in a linear reciprocating motion in the fixed frame so that the rack one and rack two respectively drive the one-way gear one and one-way gear two to rotate; at the same time, the limited sliding distance in the fixed frame, i.e., the cooperation of the limit blocks and the sharp angles set before and after the moving rack frame, makes the angle of each driving rotation of the rotating shaft fixed, which can effectively eliminate the technical effect of cumulative error. The present invention has a simple structural design and strong stability. By moving the limit blocks set before and after the rack frame, the rotating shaft rotates at a certain angle each time; by adjusting the number of teeth of the rack and the gear, the angle of each rotation can be changed, which eliminates the cumulative error. The rotating shaft can be driven to rotate back and forth by rack one and rack two, achieving the technical effect of reciprocating two-way drive, with high driving efficiency and strong practicality.

[0021] Embodiment 1:

[0022] Combined with Figures 1 to 3 A linear reciprocating motion conversion rotary motion mechanism, comprising a fixed frame 1, a movable rack frame 2 slidably connected to the fixed frame 1 is arranged inside the fixed frame 1, a rotating shaft 3 is arranged inside the movable rack frame 2, the rotating shaft 3 is rotatably connected to the fixed frame 1, and a one-way gear 1 4 and a one-way gear 2 5 are sleeved on the rotating shaft 3;

[0023] A rack 2 - 1 cooperating with a one-way gear 4 is arranged on one side of the movable rack frame 2, and a rack 2 - 2 cooperating with a one-way gear 2 5 is arranged on the other side of the movable rack frame 2.

[0024] A preferred implementation of this embodiment is that one end of the rotating shaft 3 extends out of the fixed frame 1 and is connected to a dividing turntable 6, the outer ring of the dividing turntable 6 is evenly provided with a plurality of sharp corners 6-1, the front and rear of the movable rack frame 2 are provided with limit blocks 2-3 that cooperate with the sharp corners 6-1, and the limit blocks 2-3 are two staggered and symmetrically arranged. The rack 1 2-1 and the rack 2 2-3 are staggered and oppositely arranged, and the one-way gear 1 2-1 and the one-way gear 2 2-2 have the same rotation direction.

[0025] In specific implementation, the moving rack frame slides forward, driving rack 1 and rack 2 to move forward, rack 1 cooperates with one-way gear 1, and rack 2 cooperates with one-way gear 2, driving one-way gear 1 and one-way gear 2 to rotate clockwise. At this time, one-way gear 1 drives the rotating shaft to rotate; while one-way gear 2 idles. That is, when the moving block slides forward, the rotating shaft rotates in the positive direction.

[0026] The moving rack frame slides backward, driving rack 1 and rack 2 to move backward. Rack 1 cooperates with one-way gear 1, and rack 2 cooperates with one-way gear 2, driving one-way gear 1 and one-way gear 2 to rotate counterclockwise. At this time, one-way gear 1 is idle, while one-way gear 2 drives the rotating shaft to rotate clockwise. That is, when the moving block slides backward, the rotating shaft also rotates in the positive direction.

[0027] Thus, the technical effect of bidirectional driving and unidirectional output of the steering shaft is achieved. During the sliding process of the moving frame, the rotation direction of the one-way gear 1 and the one-way gear 2 is always the same.

[0028] A preferred implementation of this embodiment is that a hole 1-1 is provided at the bottom of the fixed frame 1, a connecting member 7 is slidably provided in the hole 1-1, one end of the connecting member 7 is fixedly connected to the moving rack frame 2, and the connecting member 7 is used to connect the reciprocating linear motion mechanism to drive the moving rack frame 2 to perform reciprocating linear motion. The fixed frame 1 is rectangular, the moving rack frame 2 reciprocates along the length direction of the fixed frame 1, and the rack 1 2-1 and the rack 2 2-2 are both provided along the length direction of the moving rack frame 2.

[0029] In the specific implementation of the present invention, slide rails are arranged on both sides of the movable rack frame, and slide grooves cooperating with the slide rails are arranged on both sides of the fixed frame. The connecting piece is pulled to move back and forth, thereby driving the movable rack frame to slide back and forth in the fixed frame. Four sharp corners are arranged around the turntable, and the sharp corners are triangular; and a notch cooperating with the sharp corners is arranged on one side of the limit block.

[0030] Each one-way sliding of the mobile rack frame drives rack 1 and rack 2 to slide one-way, and then drives one-way gear 1 and one-way gear 2 to rotate at a certain angle. After each sliding, the limit block is stuck with the sharp corner, so that the angle of each turntable rotation is 90 degrees, avoiding cumulative errors.

[0031] The sharp angle of the turntable can also be set to 6, 8, etc. according to the needs, and the angle of each rotation can also be adjusted according to the needs. When adjusting, the number of teeth of the rack can be adjusted to achieve the effect of adjusting the rotation angle.

[0032] The utility model can be used in the field of continuous motion, such as an engine; and can also drive a dividing turntable to rotate for one-way control in industrial automation.

[0033] The present invention and its embodiments are described above, and such description is not restrictive. The drawings show only one embodiment of the present invention, and the actual structure is not limited thereto. In short, if ordinary technicians in the field are inspired by it, without departing from the purpose of the invention, they can design a structure and embodiment similar to the technical solution without creativity, which should belong to the protection scope of the present invention.
