[0004] Therefore, it is necessary to provide a new direct drive compact transmission structure to solve the above technical problems. UTILITY MODEL CONTENTS

[0005] To solve the above technical problems, the utility model provides a direct drive compact transmission structure, which solves the problem that in prior art, when motor is directly driven, since the length of its output end is fixed, it will lead to installation and cooperation difficulty, affecting subsequent use.

[0006] The direct drive compact transmission structure provided by the utility model includes a base, a motor is installed on the base, a first pulley is installed on the output end of the motor, a support seat is fixed on one side of the base, an installation shaft is movably arranged on the support seat, a second pulley is installed on the installation shaft, and the first pulley and the second pulley are connected by a belt.

[0007] An adjusting spline is fixed on the installation shaft, a sliding cylinder is slidably arranged on the adjusting spline, and a connecting sleeve with one end in closed form is fixed on the sliding cylinder.

[0008] In a preferred embodiment, an adjusting ring is movably arranged on the sliding cylinder, a limiting seat is arranged on one side of the adjusting ring, a threaded sleeve is movably arranged on the limiting seat, a threaded jack is threadedly connected to the threaded sleeve, and the threaded jack is fixedly connected with the adjusting ring.

[0009] In a preferred embodiment, two side seats are fixed on the support seat at intervals, a worm is movably arranged on the two side seats, a worm wheel is installed on the threaded sleeve, and the worm wheel is engaged with the worm.

[0010] In a preferred embodiment, the threaded jack is subjected to galvanizing treatment.

[0011] In a preferred embodiment, a shaking hand is installed on the worm.

[0012] The beneficial effects of this utility model are:

[0013] When this transmission structure is in use, the connecting sleeve can be used to install transmission components and play the role of outputting power. When the motor starts, it can drive the first pulley to rotate. Under the transmission action of the two pulleys and the belt, the mounting shaft can rotate. Under the action of adjusting the spline, the sliding cylinder and the connecting sleeve will rotate to complete the drive. The power of the motor is transmitted to the connecting sleeve through the belt, which can play the role of overload protection.

[0014] When the position of the connecting sleeve needs to be adjusted, the operator only needs to turn the crank to drive the worm gear to rotate. Under the transmission action of the worm gear and worm wheel, the threaded push rod will drive the sliding cylinder to slide along the mounting shaft. The operation is simple and convenient.
