[0029] The following embodiments of the present invention are described in further detail with reference to the accompanying drawings and examples. The following examples are used to illustrate the present invention, but are not intended to limit the scope of the present invention.

[0030] like Figures 1 to 4 As shown, the embodiment of the present invention provides a transmission assembly of a gear 108 and a cylindrical pin 104, comprising:

[0031] Base 100;

[0032] The column 102 is provided on the base 100. A plurality of cylindrical pins 104 are provided on the column 102 at intervals along the height direction of the column 102. The cylindrical pins 104 are adapted to slide relative to the column 102 along the axial direction of the cylindrical pins 104.

[0033] A slider 106 is slidably disposed on the column 102 , and a gear 108 is provided on the slider 106 for cooperating with the cylindrical pin 104 ;

[0034] The driving member 110 is in transmission connection with the gear 108 . When the driving member 110 is in motion, the gear 108 cooperates with the cylindrical pin 104 to drive the slider 106 to move along the height direction of the column 102 .

[0035] According to the gear 108 and cylindrical pin 104 transmission assembly provided by the embodiment of the present invention, a compact design of the transmission assembly is achieved through the ingenious cooperation of the column 102, the cylindrical pin 104, the slider 106 and the gear 108. At the same time, the meshing of the gear 108 and the cylindrical pin 104 ensures the stability and reliability of the transmission and reduces the noise and vibration during the transmission process. Since the cylindrical pin 104 is designed to slide relative to the column 102, the position or number of the cylindrical pin 104 can be adjusted as needed in actual application. Not only can the position or number of the cylindrical pin 104 be adjusted to match different transmission requirements, but the position or number of the cylindrical pin 104 can also be adjusted to limit the sliding stroke of the slider 106 relative to the column 102, thereby effectively limiting the sliding position of the slider 106. That is, the sliding design of the cylindrical pin 104 relative to the column 102 improves the flexibility and adaptability of the gear 108 and cylindrical pin 104 transmission assembly. The transmission system of gear 108 and cylindrical pin 104 offers high transmission efficiency and reduces energy loss. Furthermore, its compact structure and minimal moving parts reduce energy consumption and maintenance costs. The simple structure of the transmission assembly of gear 108 and cylindrical pin 104 makes it easy to maintain and overhaul.

[0036] Please continue to see Figures 1 to 4 The embodiment of the present invention provides a transmission assembly of a gear 108 and a cylindrical pin 104 , which mainly includes a base 100 , a column 102 , a slider 106 and a driving member 110 .

[0037] The base 100 serves as the supporting foundation of the entire transmission assembly, ensuring that all components can be stably and firmly installed thereon.

[0038] The column 102 is arranged perpendicular to the base 100 and serves as a guide for the movement of the slider 106. A plurality of cylindrical pins 104 are arranged at intervals along the height of the column 102. These cylindrical pins 104 are designed to slide relative to the column 102 along their axial direction (i.e., perpendicular to the column 102). This design allows the cylindrical pins 104 to move along the axial direction relative to the column 102.

[0039] The slider 106 is slidably mounted on the column 102 and is capable of freely moving in the height direction of the column 102. The slider 106 is provided with a gear 108 that cooperates with the cylindrical pin 104. This design allows the slider 106 to slide relative to the column 102 when the gear 108 engages with the cylindrical pin 104.

[0040] The driving member 110 is in transmission connection with the gear 108 and is the power source for driving the slider 106. When the driving member 110 is in motion, the power is transmitted to the slider 106 through the cooperation of the gear 108 and the cylindrical pin 104, thereby driving the slider 106 to move along the height direction of the column 102.

[0041] It is understood that when the transmission ratio between the gears 108 and the cylindrical pins 104 needs to be adjusted, this can be achieved by adjusting the number of cylindrical pins 104 or moving the positions of the cylindrical pins 104. For example, if six cylindrical pins 104 are provided on the column 102, and if the gears 108 need to be in one-to-one transmission engagement with the cylindrical pins 104, the six cylindrical pins 104 can be uniformly installed on the first side of the column 102. When the gears 108 need to be in transmission engagement with an odd number of cylindrical pins 104, the even number of cylindrical pins 104 can be removed or pushed to the second side of the column 102 so that the ends of the even number of cylindrical pins 104 are flush with the first side of the column 102, thereby achieving the above-mentioned purpose.

[0042] Alternatively, when it is necessary to achieve sliding limitation of the slider 106 by adjusting the position of the cylindrical pin 104, the cylindrical pin 104 at the top and the cylindrical pin 104 at the bottom can be pushed to the second side of the column 102, so that the ends of the cylindrical pin 104 at the top and the cylindrical pin 104 at the bottom are flush with the first end of the column 102, so that the sliding position of the slider 106 can be limited on the second side of the column 102.

[0043] According to an embodiment of the present invention, a sliding groove 112 is provided on the slider 106 , and the sliding groove 112 is engaged with the column 102 . The slider 106 is adapted to be slidably connected to the column 102 through the sliding groove 112 .

[0044] In one embodiment of the present invention, a slide groove 112 is added to the slider 106. This design allows the slide groove 112 to be clamped on the column 102, and through the sliding contact between the slide groove 112 and the column 102, the slider 106 can move smoothly along the height direction of the column 102.

[0045] The slide groove 112 on the slider 106 is designed to match the shape of the column 102, ensuring that the slider 106 can be firmly and stably connected to the column 102. The shape and size of the slide groove 112 are precisely calculated to provide sufficient sliding area and guidance, thereby ensuring the stability and accuracy of the slider 106 during movement.

[0046] The locking mechanism between the slide slot 112 and the column 102 ensures that the slider 106 will not easily separate from the column 102 due to external forces. This design not only improves transmission reliability, but also ensures that the slider 106 maintains good contact with the column 102 during movement, further enhancing transmission stability and efficiency. In other words, in this embodiment of the utility model, the slider 106 can only slide relative to the column 102 along the height direction of the column 102.

[0047] Through the sliding connection between the slide groove 112 and the column 102, the slider 106 can move freely along the height direction of the column 102. This design allows the slider 106 to adjust its position as needed to adapt to different transmission requirements and working conditions.

[0048] The snap-fit ​​mechanism between the chute 112 and the column 102 significantly enhances the stability of the slider 106 during movement. This design reduces the possibility of the slider 106 deviating from the predetermined trajectory due to external forces, thereby improving the accuracy and reliability of the transmission. The sliding connection between the chute 112 and the column 102 reduces friction and resistance, allowing the slider 106 to move more smoothly along the column 102. This design not only improves the efficiency of the transmission, but also reduces energy loss, thereby reducing the energy consumption of the equipment. The chute 112 design simplifies the connection process between the slider 106 and the column 102, making installation and maintenance easier. In addition, the wear resistance and durability of the chute 112 also increase the service life of the transmission assembly and reduce the frequency of replacement and maintenance.

[0049] According to one embodiment of the present invention, the slider 106 includes:

[0050] A first sliding portion 114 , wherein the sliding groove 112 is disposed on the first sliding portion 114 ;

[0051] The second sliding portion 116 is connected to the first sliding portion 114 , and the gear 108 is disposed on the second sliding portion 116 .

[0052] In one embodiment of the present invention, the slider 106 is designed to include two main parts: a first sliding part 114 and a second sliding part 116. This design not only enhances the structural strength of the slider 106, but also improves its stability and efficiency during the transmission process.

[0053] The first sliding portion 114 is the part of the slider 106 that directly contacts the column 102 and is provided with a sliding groove 112. The design of the sliding groove 112 allows the slider 106 to be securely attached to the column 102, and through the sliding connection, achieves smooth movement along the height of the column 102. The material and shape of the first sliding portion 114 are carefully selected and designed to minimize friction and wear between it and the column 102, while providing sufficient strength and durability.

[0054] The second sliding portion 116 is connected to the first sliding portion 114 and is provided with a gear 108. The engagement of the gear 108 with the cylindrical pin 104 is a key component of the transmission process, responsible for transmitting the power from the driver 110 to the slider 106, thereby driving the slider 106 along the column 102. The material of the second sliding portion 116 and the design of the gear 108 have been optimized to ensure smooth and accurate engagement between the gear 108 and the cylindrical pin 104, while also reducing friction and wear.

[0055] A reinforcing rib 124 or other structural elements may be provided between the first sliding portion 114 and the second sliding portion 116 to enhance the overall structural strength and stability of the slider 106. These design elements not only improve the durability of the slider 106 but also enable it to better adapt to various working environments and transmission requirements.

[0056] By dividing the slider 106 into a first sliding portion 114 and a second sliding portion 116, the structures and materials of these two parts can be optimized, thereby improving the overall stability of the slider 106. This design reduces the possibility of the slider 106 deviating from the predetermined trajectory due to external forces during transmission, thereby improving transmission accuracy and reliability. The design of the slide groove 112 of the first sliding portion 114 and the gear 108 of the second sliding portion 116 have both been optimized to reduce friction and wear. This design not only improves transmission efficiency but also reduces energy loss, thereby reducing the energy consumption of the equipment.

[0057] According to an embodiment of the present invention, a rotating shaft 118 is rotatably connected to the second sliding portion 116 , and the rotating shaft 118 rotates synchronously with the gear 108 .

[0058] In one embodiment of the present invention, a rotating shaft 118 is additionally provided on the second sliding portion 116, and the rotating shaft 118 rotates synchronously with the gear 108. This design further enhances the functionality and efficiency of the transmission assembly of the gear 108 and the cylindrical pin 104.

[0059] The rotating shaft 118 is designed to be rotatably connected to the second sliding portion 116, and this connection allows the rotating shaft 118 to rotate freely within the second sliding portion 116. At the same time, the rotating shaft 118 and the gear 108 achieve synchronous rotation, that is, when the rotating shaft 118 rotates, the gear 108 also rotates at the same speed and direction.

[0060] In order to achieve synchronous rotation of the shaft 118 and the gear 108, a key connection, a spline connection, a pin connection or other types of synchronous transmission mechanisms may be used. These mechanisms ensure a close fit and accurate transmission between the shaft 118 and the gear 108, thereby improving the stability and efficiency of the transmission.

[0061] By achieving synchronized rotation between shaft 118 and gear 108, friction and energy loss during the transmission process can be further reduced. This design not only improves transmission efficiency but also makes the entire transmission assembly more energy-efficient and environmentally friendly. The synchronized rotation mechanism ensures a tight fit and accurate transmission between shaft 118 and gear 108, thereby improving transmission stability. This design reduces equipment failures and downtime caused by unstable transmission. By adding shaft 118 and the synchronized rotation mechanism, the transmission assembly can better adapt to various working environments and transmission requirements. This design increases the flexibility and adaptability of the transmission assembly, enabling its wide application in various mechanical equipment.

[0062] According to an embodiment of the present invention, the driving member 110 includes a handle, which is connected to a rotating shaft 118 , and the rotating shaft 118 rotates synchronously with the handle.

[0063] In one embodiment of the present invention, the driving member 110 is designed to include a handle, and the handle is synchronously rotated with the rotating shaft 118. This design provides users with a more intuitive and convenient operation method, while further enhancing the functionality and practicality of the transmission assembly of the gear 108 and the cylindrical pin 104.

[0064] The handle is the part that the user directly operates, ensuring that the user can hold it comfortably and operate it easily. The design of the handle also takes into account ergonomic principles to reduce user fatigue during use.

[0065] The handle and the shaft 118 are synchronously rotated, that is, when the handle rotates, the shaft 118 also rotates at the same speed and direction, ensuring a close fit and accurate transmission between the handle and the shaft 118, thereby improving the stability and efficiency of the transmission.

[0066] By designing a drive member 110 that includes a handle and achieving synchronous rotation of the handle and rotating shaft 118, users can operate the transmission assembly more intuitively and conveniently. This design not only improves the user experience but also reduces operational difficulty and the risk of misoperation. The synchronous rotation connection ensures a tight fit and accurate transmission between the handle and rotating shaft 118, thereby improving transmission efficiency. This design reduces energy loss and equipment failure caused by unstable transmission. By adding a handle and synchronous rotation connection, the transmission assembly can better adapt to various working environments and operational requirements. This design increases the flexibility and adaptability of the transmission assembly, enabling its wide application in various mechanical equipment.

[0067] According to an embodiment of the present invention, an elastic return member 120 is disposed between the pillar 102 and the first sliding portion 114 .

[0068] In one embodiment of the present invention, an elastic reset member 120 is provided between the column 102 and the first sliding portion 114. This design is intended to enhance the stability and self-reset capability of the slider 106 during the transmission process, thereby further improving the performance and reliability of the entire transmission assembly.

[0069] The elastic reset member 120 can be a spring, a tension spring or other types of elastic elements. The selection of these elements depends on factors such as their elastic modulus, rigidity, durability, etc., to ensure that they can provide enough restoring forces and stability during the transmission process.

[0070] The elastic return member 120 is installed between the column 102 and the first sliding portion 114 and can be fixed to the column 102 and the first sliding portion 114 by bolts, snaps, or other connection methods. This installation method ensures that the elastic return member 120 can provide a stable return force when the slider 106 moves, while avoiding malfunctions caused by loosening or falling off.

[0071] When the slider 106 is subjected to an external force and moves along the column 102, the elastic return member 120 is stretched. Once the external force disappears, the elastic return member 120 releases its stored elastic potential energy, pushing the slider 106 back to its initial position or predetermined position. This self-resetting capability not only improves transmission stability but also reduces equipment failures caused by misoperation or external interference. Furthermore, when the user turns the handle, the provision of the elastic return member 120 can also increase a certain damping effect, preventing damage to the transmission assembly of the gear 108 and the cylindrical pin 104.

[0072] The elastic return element 120 provides a stable restoring force for the slider 106, enabling it to maintain its predetermined position or trajectory during transmission. This design reduces equipment failure and downtime caused by the slider 106 deviating from its predetermined trajectory. By installing the elastic return element 120, the slider 106 automatically returns to its initial or predetermined position upon removal of the external force. This self-resetting capability not only improves transmission reliability but also reduces user operational difficulty and the risk of misoperation.

[0073] According to an embodiment of the present invention, a connecting head 122 is provided on the column 102 , and two ends of the elastic return member 120 are connected to the connecting head 122 and the first sliding portion 114 .

[0074] In one embodiment of the present invention, a connector 122 is added to the column 102, and the two ends of the elastic return member 120 are respectively connected to the connector 122 and the first sliding portion 114. This design is intended to further accurately control the installation position and force direction of the elastic return member 120, thereby optimizing the stability and return effect of the slider 106 during the transmission process.

[0075] The connector 122 is designed to fit tightly with the column 102 and be fixed at a predetermined position on the column 102, ensuring a firm and reliable connection between the connector 122, the elastic return member 120, and the first sliding portion 114. The design of the connector 122 also takes into account the need for easy installation and removal to simplify the maintenance process.

[0076] The ends of the elastic return member 120 are respectively fixed to the connector 122 and the first sliding portion 114 by appropriate connection methods (such as bolts, snaps, welding, etc.). This installation method ensures that the elastic return member 120 can stably provide the return force when the slider 106 moves, while avoiding malfunctions caused by loosening or falling off.

[0077] In addition, by adjusting the position and shape of the connector 122, the direction of the force of the elastic return member 120 can be precisely controlled. This design enables the elastic return member 120 to provide an appropriate return force when the slider 106 moves, helping the slider 106 to stably return to its initial position or predetermined position.

[0078] By precisely controlling the installation position and force direction of the elastic return member 120, the reset accuracy of the slider 106 can be further improved. This design reduces equipment failure and downtime caused by inaccurate reset. The presence of the connector 122 enables the elastic return member 120 to provide a more stable reset force, thereby enhancing the stability of the slider 106 during the transmission process. This design reduces the risk of failure caused by the slider 106 deviating from the predetermined trajectory.

[0079] According to one embodiment of the present invention, a reinforcing rib 124 is provided between the column 102 and the base 100 .

[0080] In one embodiment of the present invention, a reinforcing rib 124 is provided between the column 102 and the base 100. This design is intended to increase the strength and rigidity of the structural connection, thereby improving the load-bearing capacity and durability of the entire transmission assembly.

[0081] The ribs 124 are designed as additional structural elements connecting the columns 102 and the base 100. They can be in the form of plates, rods, or other shapes to maximize their reinforcing effect. The layout of the ribs 124 is also optimized to ensure that they can effectively distribute and resist loads from all directions.

[0082] The connection between the reinforcement 124 and the column 102 and the base 100 may include welding, bolting, riveting, etc. The selection of these connection methods depends on the specific application scenario and requirements to ensure the strength and durability of the connection.

[0083] The presence of reinforcing ribs 124 significantly increases the strength and rigidity of the connection between the column 102 and the base 100. This design enables the entire transmission assembly to withstand greater loads and impacts, thereby improving its load-bearing capacity and durability. The layout of reinforcing ribs 124 helps optimize stress distribution and reduce the risk of structural damage caused by stress concentration. This design extends the service life of the transmission assembly and reduces maintenance costs.

[0084] According to one embodiment of the present invention, the intervals between the plurality of cylindrical pins 104 are equal.

[0085] In one embodiment of the present invention, the plurality of cylindrical pins 104 are designed to be evenly distributed on the column 102, that is, the spacing between the plurality of cylindrical pins 104 is equal. This design is intended to optimize the force distribution during the transmission process by ensuring the uniform spacing between the cylindrical pins 104, thereby improving transmission efficiency and stability.

[0086] The cylindrical pins 104 are designed to be evenly distributed throughout the transmission mechanism, with consistent spacing between each pin. This layout ensures that the forces during transmission are evenly distributed across each pin 104, thus preventing excessive wear or damage caused by uneven force distribution. By ensuring uniform spacing between the cylindrical pins 104, the forces during transmission are evenly distributed across each pin 104. This design reduces excessive wear or damage caused by uneven force distribution, improving transmission efficiency and stability.

[0087] According to an embodiment of the present invention, along the height direction of the column 102 , through holes 126 corresponding to the plurality of cylindrical pins 104 are opened on the column 102 , and the cylindrical pins 104 are loosely fitted in the through holes 126 .

[0088] In one embodiment of the present invention, the column 102 is designed to have through-holes 126 along its height, corresponding one-to-one with the cylindrical pins 104. A clearance fit is employed between the cylindrical pins 104 and the through-holes 126. This design aims to optimize transmission efficiency and assembly flexibility by ensuring that the cylindrical pins 104 can be easily inserted and secured in the through-holes 126 of the column 102 while maintaining a certain clearance to allow for slight movement or adjustment.

[0089] Through holes 126 are formed in the column 102, corresponding one to each of the cylindrical pins 104. The size and shape of the through holes 126 are designed to match the cylindrical pins 104, but with a certain amount of clearance to allow the cylindrical pins 104 to move freely within the through holes 126. The through holes 126 are evenly distributed along the height of the column 102, ensuring a uniform layout of the cylindrical pins 104 on the column 102.

[0090] The cylindrical pin 104 is designed to easily insert into the through hole 126 of the column 102 and maintain a stable fixed state. Due to the use of a clearance fit, the cylindrical pin 104 has a certain amount of space to move within the through hole 126, which helps absorb and distribute impact loads during transmission, improving the stability and durability of the transmission.

[0091] More importantly, when the transmission ratio between the cylindrical pin 104 and the gear 108 needs to be adjusted, or when the cylindrical pin 104 needs to be used to limit the slider 106, the above purpose can be achieved by adjusting the position or number of the cylindrical pin 104. By adopting a clearance fit, the adjustment convenience between the cylindrical pin 104 and the through hole 126 is improved, which helps to improve the flexibility and efficiency of assembly and reduce the difficulty and cost of assembly. The clearance fit between the cylindrical pin 104 and the through hole 126 helps to absorb and disperse the impact load during the transmission process, reducing the risk of damage caused by stress concentration. At the same time, the uniform layout of the cylindrical pins 104 also helps to optimize the force distribution during the transmission process, improving the stability and efficiency of the transmission.
