Description

Technical Field

[0001] This utility model relates to the field of transmission steel pin technology, and in particular to a transmission steel pin with a handle for tractors. Background Technology

[0002] Transmission steel pins are mainly used for connection and transmission, ensuring the accurate transmission of power and torque between mechanical parts. Agricultural machinery transmission steel pins are mainly used to connect transmission components in agricultural machinery such as tractors, such as drive shafts and universal joints, to ensure the accurate transmission of power and torque between mechanical parts.

[0003] Agricultural machinery typically operates in complex and variable environments, such as fields and grasslands. These environments may contain impurities such as dust, sand, and crop residues. These impurities can easily enter the transmission system and cause wear on the transmission pins. When replacing the transmission pins, the usual procedure is to remove the cotter pin that positions the pin, then tap the bottom of the transmission pin with a hammer to move it upwards. Next, align the transmission pin with the bottom of the transmission pin and tap it with a hammer. The transmission pin then transfers the force to the transmission pin, causing it to completely disengage from the drive shaft.

[0004] However, when the transmission steel pin of agricultural machinery is damaged and the agricultural machinery cannot drive the drive shaft to adjust the orientation of the pin cap end of the transmission steel pin, the transmission steel pin needs to be removed from one end of the pin cap due to the space limitation of the agricultural machinery. The pin cap is usually cylindrical and tightly attached to the drive shaft, which makes the removal of the transmission pin difficult. Therefore, a transmission steel pin with a handle for tractors is designed to solve the above problems. Utility Model Content

[0005] The purpose of this utility model is to solve the problems existing in the above-mentioned background art, and to propose a tractor transmission steel pin with a handle.

[0006] The technical problem to be solved by this utility model is to provide a tractor transmission steel pin with a handle, which solves the problem of inconvenient disassembly of transmission steel pins in agricultural machinery in the prior art.

[0007] This utility model provides a tractor transmission steel pin with a handle, including a steel pin body, a pin cap, and a cotter pin. The top of the steel pin body is integrally formed with a pin cap, and a through hole is opened at the bottom of the steel pin body. A cotter pin is inserted through the through hole. The left and right ends of the side of the pin cap are provided with an embedding groove, and a handle is rotatably arranged in the embedding groove.

[0008] Preferably, an opening is provided at the bottom of the handle, and the two ends of the opening are respectively embedded in the embedding groove.

[0009] Preferably, the handle has a downward-curving arc-shaped groove at the center of its upper part.

[0010] Preferably, the angle corresponding to the arc groove is 120-180°, and the diameter corresponding to the arc groove is equal to the diameter of the drive shaft connected by the drive steel pin.

[0011] Preferably, the diameter of the through hole is equal to the central diameter of the cotter pin, and the diameter of the through hole is smaller than the width of the bent end of the cotter pin.

[0012] Compared with the prior art, this utility model has at least the following beneficial effects:

[0013] 1. When it is necessary to disassemble the steel pin body from the direction of the pin cap, the cotter pin is first removed. With the handle, when the friction between the steel pin body and the drive shaft is small, the steel pin body can be disassembled by grasping the handle and pulling upwards. The disassembly is simple and convenient. When the friction between the steel pin body and the drive shaft is large, a rod-shaped tool is used to pass through the handle and rotate the handle to make the steel pin body rotate, thereby disassembling the steel pin body. Alternatively, the steel pin body can be disassembled by passing a rod-shaped tool through the handle and prying upwards. The operation is simple and convenient.

[0014] 2. This utility model, by providing an arc-shaped groove, allows for easy disassembly of the steel pin body from the direction of the pin cap. First, remove the cotter pin. Then, grasp both ends of the handle and rotate it along the groove. This causes the arc-shaped groove above the handle to contact the drive shaft, forcefully impacting the drive shaft. The handle exerts an upward force on the pin cap, causing it to move upwards, thus moving the steel pin body upwards and disassembling it. Alternatively, by rotating the handle, the arc-shaped groove on the handle can contact the drive shaft. Then, a hammer can be used to strike the arc-shaped groove on the handle against one side of the steel pin body. The arc-shaped groove moves to the left along the drive shaft, causing the handle to rotate closer to the steel pin body. This pushes the pin cap upwards, achieving the disassembly of the steel pin body. The operation is simple and convenient. Attached Figure Description

[0021] Example:

[0022] like Figures 1-3 As shown, an embodiment of this utility model provides a steel pin with a handle for a tractor, including a steel pin body 1, a pin cap 2, and a cotter pin 3. The top of the steel pin body 1 is integrally formed with the pin cap 2, and a through hole 101 is provided at the bottom of the steel pin body 1. The cotter pin 3 is disposed through the through hole 101. The left and right ends of the side of the pin cap 2 are provided with an embedding groove 201, and a handle 4 is rotatably disposed in the embedding groove 201.

[0023] When it is necessary to disassemble the steel pin body 1 from the direction of pin cap 2, first remove the cotter pin. With the handle 4 in place, when the friction between the steel pin body 1 and the drive shaft is small, the steel pin body 1 can be disassembled by grasping the handle 4 and pulling it upward. The disassembly is simple and convenient. When the friction between the steel pin body 1 and the drive shaft is large, the steel pin body 1 can be disassembled by using a rod-shaped tool to pass through the handle 4 and rotating the handle 4. Alternatively, the steel pin body 1 can be disassembled by using a rod-shaped tool to pass through the handle 4 and prying it upward. The operation is simple and convenient.

[0024] In this embodiment, an opening is provided at the bottom of the handle 4, and the two ends of the opening are respectively embedded in the embedding groove 201, so that the handle 4 can rotate along the embedding groove 201 and the handle 4 will not block the top of the pin cap 2. When the Fangbaini steel pin body 1 is installed, the steel pin body 1 can be installed by hitting the pin cap 2 with a hammer.

[0025] In this embodiment, a downward-curving arc groove 401 is provided at the center of the upper part of the handle 4.

[0026] In this embodiment, the angle corresponding to the arc groove 401 is 120-180°, and the diameter corresponding to the arc groove 401 is equal to the diameter of the transmission shaft connected by the transmission steel pin, so that the arc groove 401 can be attached to the transmission shaft for the removal of the steel pin body 1.

[0027] With the arc groove 401 provided, when it is necessary to disassemble the steel pin body 1 from the direction of the pin cap 2, first remove the cotter pin 3, then grasp the left and right ends of the handle 4, and rotate the handle 4 along the embedded groove 201 so that the arc groove 401 above the handle 4 contacts the drive shaft, and the arc groove 401 forcefully impacts the drive shaft. The handle 4 generates an upward reverse force on the pin cap, causing the pin cap 2 to move upward, driving the steel pin body 1 to move upward, thus achieving the disassembly of the steel pin body 1. Alternatively, by rotating the handle 4 so that the arc groove 401 on the handle 4 contacts the drive shaft, and then using a hammer to strike the arc groove 401 part on the handle 4 on one side of the steel pin body 1, the arc groove 401 moves to the left along the drive shaft, thereby causing the handle 4 to rotate closer to the side of the steel pin body 1. The handle 4 pushes the pin cap 2 upward, thus achieving the effect of disassembling the steel pin body 1. The operation is simple and convenient.

[0028] In this embodiment, the diameter of the through hole 101 is equal to the central diameter of the cotter pin 3, and the diameter of the through hole 101 is smaller than the width of the bent end of the cotter pin 3, so as to prevent the bent end of the cotter pin from passing through the through hole 101 and ensure that the cotter pin 3 positions the steel pin body 1.

[0029] The above are merely preferred embodiments of this utility model. It should be noted that, for those skilled in the art, several modifications and improvements can be made without departing from the concept of this utility model, and these should also be considered within the scope of protection of this utility model. These will not affect the implementation effect of this utility model or the practicality of the patent.
