Detailed Description
The following specific embodiments are merely illustrative of the present invention, and are not intended to limit the present invention, and those skilled in the art can make modifications of the present embodiments without inventive contribution as required after reading the present specification, but all the embodiments are protected by patent laws and protection within the scope of the present invention.
The scheme is realized by the following technical means:
example 1: a transmission connecting device comprises a rotary driving part 1, a rotary driven part 2 and a movable connecting part 3 arranged between the rotary driving part 1 and the rotary driven part 2. Specifically, the rotary driving member 1 is a belt pulley mounted on a fixed bracket, and the belt pulley can rotate around a fixed axis under the condition of external driving motor belt connection transmission; the rotary driven part 2 is a shaft for driving other parts to rotate, and an installation section for sleeving the movable connecting part 3 is formed at the lower end of the shaft; the main body of the movable connecting piece 3 is cylindrical with a central hole and is sleeved on the mounting section. At this moment the lateral wall of installation section forms location spigot surface 2a, 3 through-hole inner walls of swing joint spare form and lean on spigot surface 3a, location spigot surface 2a with lean on spigot surface 3a to lean on the laminating mutually for swing joint spare 3 can remove along the axial of driven shaft. All set up flutedly on swing joint spare 3 and driven shaft for the installation connecting key forms keyway structure 11, and swing joint spare 3 rotates this moment and will drive the driven shaft and rotate. The upper end part of the belt pulley as the rotary driving piece 1 is provided with a notch groove which is sunken downwards, and the side surface wall of the notch groove forms a first abutting surface 1a along the vertical direction; the lower end of the movable connecting piece 3 is formed with a convex portion protruding outward, and the side wall thereof forms a second abutting surface 3b in the vertical direction. When the movable connecting piece 3 moves downwards, the first abutting surface 1a and the second abutting surface 3b are abutted and abutted, the rotation of the belt pulley is transmitted to the driven rotating shaft through the structure, and when the movable connecting piece 3 moves upwards, the first abutting surface 1a and the second abutting surface 3b are not abutted and are separated from each other, so that the rotation of the belt pulley is not transmitted to the driven rotating shaft, and the separation between the parts and the cut-off of power transmission are realized.
Example 2: since the movable connecting piece 3 in the transmission connecting device needs to transmit power through rotation of the movable connecting piece, a structure for driving the movable connecting piece to move along the axial direction of the rotating driven piece 2 without influencing the rotation of the movable connecting piece 3 needs to be added. Therefore, a thrust roller bearing 5 is sleeved and installed on the outer side of the movable connecting piece 3, and a shifting block 4 is fixedly installed on the outer side of the thrust roller bearing 5. Under the action of external driving force, the shifting block 4 can move up and down along the axial direction of the rotating driven part 2; because the thrust roller bearing 5 between the shifting block 4 and the movable connecting piece 3 can transmit the axial acting force between the inner ring and the outer ring, the movable connecting piece 3 can move up and down along with the shifting block 4, and the switching between the two states of power transmission and cutting off between the rotary driving piece 1 and the rotary driven piece 2 is realized.
Further preferably, a shifting lever 6 arranged along the horizontal direction is further installed on the outer side of the shifting block 4 in order to control and operate the movement of the movable connecting piece 3 along the axial direction. The shift lever 6 comprises a driving handle 6a, a sleeving ring part 6b and a connecting section 6 c. Since the driving handle 6a is far from the rotary driving member 1, the rotary driven member 2 and the movable connecting member 3, when an external acting force is applied, the interference influence on the operation of the rotary member can be effectively avoided, and the safety of the operating device is improved while the state switching operation is more labor-saving. The cup joint ring part 6b is installed in the outside of shifting block 4, and the outside arch in both sides of shifting block 4 is formed with cylindrical end portion, and the mounting hole that supplies cylindrical end portion embedding is seted up to the both sides of cup joint ring part 6 b. The shifting block 4 is connected with the sleeving ring part 6b in a mode that the cylindrical end part protruding from the shifting block 4 is inserted into the mounting hole at the corresponding position of the sleeving ring part 6b to form a first hinge part 8, so that the shifting block 6 can rotate relative to the shifting block 4 around the center of the first hinge part 8; the end of the connecting section 6c is connected with the fixed bracket in a hinged manner to form a second hinge 9, so that the shift lever 6 can also rotate around the center of the second hinge 9. When an acting force which is upward or downward along the vertical direction is applied to the driving handle 6a of the shift lever 6, the entire shift lever 6 rotates around the rotation center of the second hinge portion 9, and at the same time, the sleeve ring portion 6b on the shift lever 6 moves up and down along the circular arc-shaped motion track. Under the action of the first hinge part 8, the shifting block 4 tends to move up and down along the circular arc track along the sleeving ring part 6 b. However, the shifting block 4 can only move along the axial direction of the rotating driven part 2, so that the situation of collision and blocking can occur in the moving process; meanwhile, as the sleeve joint ring part 6b rotates around the first hinge part 8 in the moving process, the front end and the rear end of the sleeve joint ring part 6b gradually approach the shifting block 4 along with the increase of the rotating angle of the sleeve joint ring part 6b, and interference occurs. In order to solve the above problem, a slide rail groove 10 for moving the second hinge portion 9 in the horizontal direction is further formed on the connecting section 6c, and a gap space 7 is further formed between the dial block 4 and the sleeve ring portion 6 b. In an initial state, the shift lever 6 is horizontally arranged, the main driving part and the auxiliary driving part are in a connection state, when the shift lever 6 rotates upwards around the center of the second hinge part 9, the first hinge part 8 moves upwards, at the moment, the distance between the first hinge part 8 and the second hinge part 9 tends to increase, and the second hinge part 9 is driven to move along the slide rail groove 10 to be far away from the first hinge part 8 so as to compensate the increased distance; at the same time, the bell and spigot ring portion 6b rotates about the first hinge portion 8, and the front and rear ends thereof enter the gap space 7 without interfering with other components. At the moment, the shifting block 4 transmits upward acting force to the movable connecting piece 3 through the bearing 5 and drives the movable connecting piece 3 to move upwards, so that the power transmission between the rotary driven piece 2 and the rotary driving piece 1 is cut off. When the rotary driven part 2 and the rotary driving part 1 need to be connected, the driving lever 6 only needs to be rotated downwards to restore to the horizontal position, and then the power transmission effect between the rotary driven part 2 and the rotary driving part 1 is achieved again.
The above description is only for the specific embodiments of the present invention, but the scope of the present invention is not limited thereto, and any person skilled in the art can easily think of various equivalent modifications or replacements within the technical scope of the present invention, and these modifications or replacements should be covered within the scope of the present invention. Therefore, the protection scope of the present invention shall be subject to the protection scope of the claims.
