Description

Technical Field

[0001] This invention belongs to the general technical field, specifically relating to a manually controlled, rapid engagement and disengagement device for shaft transmissions. Through simple operation, it enables rapid engagement and disengagement of the input and output shafts, thereby ensuring the reliability of the equipment's transmission and can be widely applied to similar transmission mechanisms. Background Technology

[0002] In certain shaft-type transmission processes, it is often necessary to effectively engage and disengage the input and output ends to ensure the accuracy and reliability of the mechanical transmission. In special circumstances where manual engagement and disengagement of the transmission is required, safety and reliability are compromised, and the operation is quite difficult. Summary of the Invention

[0003] The purpose of this invention is to provide a quick opening and closing device for a drive shaft, addressing the problems of low safety and reliability, and high operational difficulty in the existing technology of connecting and separating the input and output ends of the drive shaft.

[0004] The objective of this invention is achieved through the following technical solution:

[0005] The present invention provides a quick opening and closing device for a drive shaft, comprising a support base, a positioning ring, a rear connector, a drive handle, a front connector, a front positioning pin, and a rear positioning pin.

[0006] The support base has an axially connected connecting body mounting cavity in the middle, and two front and rear sections are connected. The front side wall of the support base has two symmetrical front positioning pin through holes, and the rear side wall of the support base has two symmetrically extended horizontal rear positioning pin connecting elongated holes. The lower part of the rear outer wall of the support base has two symmetrically opened shaft connecting blind holes.

[0007] The middle part of the front connector is a cylindrical positioning section with a diameter matching the diameter of the mounting cavity of the front connector of the support seat. The side wall of the cylindrical positioning section has an annular positioning groove. The rear end of the front connector is provided with a splined connecting platform. The front end of the front connector is provided with a cylindrical connecting section corresponding to the front connector of the drive shaft.

[0008] The positioning ring is an annular piece whose outer diameter matches the diameter of the mounting cavity of the rear section of the support base. The sidewall of the positioning ring has symmetrical holes for the rear positioning pin.

[0009] The rear connector has an annular outer diameter that matches the inner diameter of the positioning ring. The outer wall of the rear connector has an annular positioning groove. The inner diameter of the rear connector matches the outer diameter of the rear section connector of the drive shaft. The front end of the rear connector has a splined connecting sleeve corresponding to the rear end of the front connector.

[0010] The drive handle is composed of two parallel and fixed vertical plates. The lower part of the two vertical plates has symmetrical holes for the shaft to pass through, and the middle part of the two vertical plates has symmetrical holes for the vertically extending rear positioning pin connection.

[0011] The front connector is installed in the front connector mounting cavity of the support base. The front end of the front positioning pin passes through the front positioning pin through hole of the support base and is inserted into the annular positioning groove of the front connector, so that the front connector is rotatably connected and axially positioned in the front connector mounting cavity of the support base.

[0012] The positioning ring and the rear connector are sequentially installed into the mounting cavity of the rear connector of the support base. The lower parts of the two vertical plates of the drive handle are rotatably connected to the lower part of the rear outer wall of the support base through a rotating shaft. The front end of the rear positioning pin passes through the rear positioning pin connecting length of the drive handle, the rear positioning pin connecting length hole of the support base, and the rear positioning pin through hole of the positioning ring in sequence, and is inserted into the annular positioning groove of the rear connector, so that the rear connector and the positioning ring are rotatably connected and axially positioned.

[0013] When the drive handle is rotated forward, the positioning ring and the rear connecting body are driven to move axially forward through the rear positioning pin, so that the connecting sleeve of the rear connecting body is splinedly engaged with the connecting platform of the front connecting body; when the drive handle is rotated backward, the positioning ring and the rear connecting body are driven to move axially backward through the rear positioning pin, so that the connecting sleeve of the rear connecting body is disengaged from the connecting platform of the front connecting body.

[0014] Work process

[0015] The rear section of the drive shaft is inserted into the inner hole of the rear connector and connected by a key. The cylindrical connecting section of the front connector is inserted into the inner hole of the front section of the drive shaft. When the two drive shafts need to be connected, the drive handle is rotated forward, which drives the positioning ring and the rear connector to move axially forward through the rear positioning pin, so that the connecting sleeve of the rear connector is splinedly connected to the connecting platform of the front connector. When the two drive shafts need to be disconnected, the drive handle is rotated backward, which drives the positioning ring and the rear connector to move axially backward through the rear positioning pin, so that the connecting sleeve of the rear connector is disengaged from the connecting platform of the front connector.

[0016] Beneficial effects:

[0017] The quick-opening and closing device for the transmission shaft of the present invention has a simple structure and is easy to operate. It can realize the quick engagement and disengagement of the input end and output end of the transmission shaft, thereby ensuring the reliability of the equipment transmission. It can be widely used in similar transmission mechanisms. The transmission process can be manually operated, which is quick and convenient. Attached Figure Description
