A mechanical transmission device

Abstract

This utility model discloses a mechanical transmission device, which includes a movable rod, a fixed rod, blades, and a booster. The movable rod includes a circular seat, a gear, an opening limit, a closing limit, and an auxiliary column. The fixed rod includes a square seat, a main column, and a limiting block. The movable rod is nested on the fixed rod. The blades are installed on the movable rod in a preset order. The limiting block on the fixed rod restricts the range of motion of the movable rod. The working principle of the mechanical transmission device is that when the push wheel moves, the transmission wheel changes speed, and then the drive wheel starts to rotate. The drive wheel then drives the top blade to rotate. As the top blade rotates, it drives the secondary blade to rotate, and the secondary blade rotates, driving the bottom blade. Finally, all the blades are in a 360-degree state, and the 360-degree blades can be designed into various desired solid shapes. This design can stimulate consumers' desire for exploration, bringing them a pleasant interactive experience and a unique sense of novelty.

Description

Technical Field

[0001] This utility model relates to the field of production technology in the packaging industry, and in particular to a mechanical transmission device. Background Technology

[0002] There are many ways to rotate an object using thrust, such as by using a crankshaft or by controlling the object's script to achieve rotation along a specific axis. Most of these methods require the use of rolling bearings, rotary cylinders, or electric motors. They also usually need to consider the required thrust, inertia, stability, and safety issues. Not only are they complex to construct and costly to manufacture, but they also cannot make the object rotate locally. Summary of the Invention

[0003] To overcome the shortcomings of existing technologies, a mechanical transmission device is proposed. The working principle of this device is as follows: when the drive wheel moves, it causes the transmission wheel to change speed, which in turn causes the drive wheel to rotate. The drive wheel then drives the top blade to rotate, which in turn drives the secondary blades, which in turn drive the bottom blades, ultimately causing all the blades to rotate 360 ​​degrees. Its advantage lies in the fact that the 360-degree blades can be designed into any desired solid shape. This solves many drawbacks of existing methods that use thrust to rotate objects, such as simplifying the structure, saving energy, improving production efficiency, and increasing reliability.

[0004] To achieve the above objectives, this utility model provides the following technical solution:

[0005] The mechanical transmission device includes a movable rod, a fixed rod, blades, and a booster. The movable rod includes a round seat, a gear, an opening limit, a closing limit, and an auxiliary column. The fixed rod includes a square seat, a main column, and a limiting block. The movable rod is nested on the fixed rod. The blades need to be installed on the movable rod in a preset order. The range of motion of the movable rod is limited by the limiting block on the fixed rod. When the range is minimal, the transmission device is in a closed state; when the range is maximum, the transmission device is in an open state.

[0006] Preferably, the auxiliary column is disposed on the circular seat and is integrated with the circular seat. The auxiliary column includes a balance groove, an auxiliary column notch, and a long notch. The auxiliary column divides the blade into multiple zones by controlling the long notch. Each zone can be designed with different blade decorations in 360-degree orientation.

[0007] Preferably, the main column has a main column gap that extends from the top to the bottom of the main column, and the size of the main column gap is the same as the size of the auxiliary column gap.

[0008] Preferably, the blades include bottom blades, middle blades, and top blades. The bottom blades include a ring, a long protrusion, and a decorative part. The middle blades include several layers, each with a slide rail on the front and a slider on the back. During installation, each slider needs to be aligned with the slide rail of the next layer. The top blades include a fixing protrusion and a balancing protrusion. The number of blades needs to be arranged sequentially in a 360-degree pattern. The more blades there are, the smaller the blades become.

[0009] Preferably, the booster includes a speed-changing wheel and a transmission wheel. The speed-changing wheel is a speed-changing transmission device used between the transmission wheel and the working machine. It adjusts the speed during rotation by changing the size of its circumference and the size of its teeth.

[0010] Preferably, when the transmission wheel is subjected to force, the transmission wheel drives the gear wheel, the gear wheel drives the gear to move, and the gear drives the auxiliary column to rotate. At this time, the top blade starts to move first through the cooperation of the balancing cam and the fixing cam with the auxiliary column, and then drives the middle layer blade to rotate in sequence.

[0011] Preferably, the movable rod, fixed rod, blade, and booster are made of rigid material, such as paper, wood, acrylic, or plastic.

[0012] Compared with the prior art, the beneficial effects of this utility model are:

[0013] The mechanical transmission device described in this utility model has the advantages of simple structure, rapid action, and convenient control. For example, when applied to drawer-type packaging boxes, it can achieve 360-degree omnidirectional rotation of the blades through a simple one-way pull-out action. At the same time, the lower part of the transmission device is cleverly hidden inside the packaging box, which is not only beautiful and elegant, but also stimulates consumers' desire to explore and brings them a pleasant interactive experience. Such a design is both practical and efficient, which can not only improve the aesthetics of the packaging box, but also enhance its appeal to consumers.

[0014] The mechanical transmission device can adjust the shape, size, number of layers, and other decorative parts driven by the movable rod and fixed rod according to usage requirements. The other decorative parts also include the blades. Attached Figure Description
