Description

Technical Field

[0001] The utility model relates to the technical field of ornaments, in particular to a circulating ball type lever turning turntable automatic rotating device. Background Art

[0002] Ornamental objects, also known as decorative items or works of art, are objects created primarily for aesthetic, decorative, or collectible purposes. They can enhance the beauty of a space and the visual impact of an environment. They can also serve as educational tools, helping people understand art, history, and different cultures. Appreciating ornamental objects can also provide spiritual pleasure and relaxation, helping to reduce stress. Their aesthetic qualities can also inspire creativity and imagination. Humanities exhibitions, technology exhibitions, and science museums often feature ornamental objects representing humanities or scientific knowledge, helping adults and children understand these knowledge through appreciation. However, traditional ornamental objects have a simple operational structure, display relatively little scientific and humanistic knowledge, and are therefore less appealing. Utility Model Content

[0003] In view of the shortcomings of the existing technology, the utility model provides a circulating ball-type lever turning turntable automatic rotation device to solve the problems of low ornamental value and single operating structure of traditional ornaments.

[0004] The cam is provided with a plurality of movable lever grooves, and the outer edge of the cam is provided with a plurality of movable lever grooves. The cam is provided with a plurality of movable lever grooves in a circumferential direction. The outer edge of the cam is provided with a lever arm corresponding to each position of the movable lever groove. The end of the lever arm is provided with an ornamental blade for swinging along the penetration direction of the movable lever groove. The starting end of the lever arm is provided with a ball pocket groove. The base is provided with a guide pipe, and a plurality of power balls are rolled in the guide pipe. One end of the guide pipe is opened as a discharge port, and the other end is opened as an inlet. The base is provided with a lifting structure for lifting the lever arm near the inlet so that the ball pocket groove is close to the inlet and the power ball rolls into the ball pocket groove, and a reset structure for pushing the power ball in the ball pocket groove near the discharge port into the discharge port.

[0005] The above technical solution is beneficial in that: the turntable is divided into two parts along its center line and divided into a high potential energy zone and a low potential energy zone. Before operation, a power ball is placed in the ball pocket of each lever arm in the high potential energy zone, and each lever arm in the low potential energy zone does not accommodate a power ball, so that the overall weight of the high potential energy zone is greater than the overall weight of the low potential energy zone, thereby making the low potential energy zone part of the turntable higher than the high potential energy zone part, so that the turntable and the base are in a relatively tilted state. When the power balls are gradually installed in the high potential energy zone, the gravity along the outer edge of the turntable gradually increases, thereby making the high potential energy zone tilt relative to the low potential energy zone and causing the turntable to gradually rotate under the influence of gravity. When the turntable rotates, the power balls in the high potential energy zone will gradually approach the discharge port as the turntable rotates. At this time, the reset structure will push the power balls in the ball pocket groove near the discharge port into the discharge port. As the turntable rotates, the reset structure will push each power ball in the high potential energy zone into the discharge port, that is, into the guide pipe. When the lever arm loses the power ball, it will move to the low potential energy zone as the turntable rotates, and then be divided into the lever arm of the low potential energy zone. When the power ball pushes into the guide pipe, it will move along the guide pipe to the feed port. At the feed port, the ball pocket groove of the lever arm near the feed port is aligned with the feed port through the lifting structure, so that the power ball can roll The ball is put into the pocket, so that the lever arm accommodates the power ball and swings under the support of the power ball and the ornamental blades so that the ornamental blades are arranged perpendicular to the base. At this time, the weight of the ornamental blades plus the power ball is greater than the weight of the ornamental blades, so that the lever arm with the power ball is gradually divided into the high potential energy zone as the turntable rotates and applies a certain potential energy to the rotation of the turntable, thereby promoting the rotation of the turntable. In the above technology, the automatic replenishment and automatic replenishment of the power ball are realized by setting the lifting structure and the reset structure, so that the lever arm at the junction of the high potential energy zone and the low potential energy zone will automatically swing after accommodating the power ball and apply potential energy to the turntable, thereby making the turntable rotate and driving the power ball The lever arm of the ball moves to the high potential energy area, and the reciprocating power ball causes the turntable to rotate automatically. The entire operating principle includes the physics principle of high and low potential energy supplementation, the lever principle and the knowledge of reciprocating cycles, which helps adults or children understand scientific knowledge while appreciating it, and can inspire adults or children to explore and seek knowledge of the principles and knowledge involved. At the same time, the swinging of several ornamental blades and the switching of their relative vertical states with the base greatly improve the aesthetics, thereby enhancing the overall viewing experience. If placed in a science and technology exhibition, science and technology museum or company pavilion, it can add to the beauty of the space, enhance the visual effect of the environment, and at the same time provide spiritual pleasure and relaxation to the viewers, helping to relieve stress.

[0006] The utility model is further provided with: a connecting arm is connected to the position corresponding to each opening of the lever movable groove on the outer peripheral wall of the turntable, and a number of the connecting arms are arranged in a one-to-one correspondence with a number of lever arms. A connecting pin is rotatably connected to the end of the connecting arm and the center of the lever arm. The connecting pin is eccentrically arranged with the ornamental blade, and the end of the lever arm is connected to the center of the ornamental blade. A wrapping head is provided at the starting end of the lever arm, the ball pocket groove is opened on the wrapping head, and a notch for the power ball to roll into is opened on the outer peripheral wall of the wrapping head, the notch is connected to the ball pocket groove, the radial cross-section of the ball pocket groove is arranged in an arc shape, and the diameter of the ball pocket groove is adapted to the diameter of the power ball.

[0007] The benefit of adopting the above technical solution is that: when the power ball rolls into the ball pocket groove, it will be placed in the ball pocket groove through the notch. After the power ball is placed in the ball pocket groove, as the turntable rotates, the lifting structure no longer applies force to the ornamental blades, so that the ornamental blades fall in the lever movable groove due to their own weight, thereby driving the lever arm to swing. When the lever arm swings, the wrapped head on its top rises and drives the power ball to rise through the arc-shaped ball pocket groove. Because the weight of the ornamental blades is greater than the weight of the wrapped head plus the power ball, the lever arm can swing due to the weight of the ornamental blades, thereby realizing the resetting of the ornamental blades.

[0008] The utility model is further provided with: a guide plate is provided near the notch position of the wrapping head, a notch is provided on the bottom wall of the guide pipe discharge port along the movement trajectory of the guide plate, and the surface of the guide plate is used for allowing the power ball to fall when the guide plate is at the opening of the notch and guiding the power ball to roll into the ball pocket groove through the notch.

[0009] The benefits of adopting the above technical solution are: when the lifting structure guides the ornamental blades to lift and brings the wrapping head close to the feed port, the guide plate will move to the notch as the turntable rotates, so that the power ball at the feed port can roll into the guide plate and enter the ball pocket groove through the notch, thereby completing the accommodation of the power ball; in order to improve the efficiency and accuracy of the power ball rolling into the ball pocket groove, a hook plate is provided at the front end of the guide plate. When the turntable swings, the guide plate is mainly inserted into the feed port and the power ball is first lifted up by the hook plate and then hooked into the guide surface, so that the power ball can pass through the guide surface and be placed into the ball pocket groove through the notch.

[0010] The present invention is further provided with: the lifting structure includes a lifting baffle, the lifting baffle is arranged near the feed port and the inner wall of the lifting baffle is a lifting surface for partially contacting the outer peripheral wall of the ornamental blade and lifting the ornamental blade as the turntable rotates, a support platform is provided at the top of the lifting baffle facing the opening of the feed port, the surface of the support platform is a support surface for partially contacting the outer peripheral wall of the ornamental blade on the lever arm close to the feed port and supporting the ornamental blade so that the notch and the ball pocket groove face the feed port, and the lifting baffle is arranged on the base.

[0011] The benefit of adopting the above technical solution is that: when the lever arm approaches the lifting baffle, the ornamental blades will first contact the lifting surface. Since the lifting baffle is in a fixed state, the ornamental blades are gradually lifted up by the lifting baffle as the turntable rotates, so that the ornamental blades are lifted upward in the movable groove of the lever. At the same time, the wrapping head gradually falls and approaches the feed port of the guide pipe. The support platform is set to make the support surface contact with the ornamental blades as the turntable rotates after the ornamental blades are lifted to a certain height, and the ornamental blades are supported and supported by the support surface due to their own weight, thereby realizing the temporary positioning of the wrapping head at the feed port, thereby ensuring that the power ball can roll smoothly into the ball pocket slot.

[0012] The utility model is further provided with: a fixed shaft is provided on the inclined plate, the turntable is coaxially arranged with the fixed shaft and the turntable rotation is arranged on the end of the fixed shaft, the end of the fixed shaft is coaxially connected to the limiting shaft, the reset structure includes a push rod, the push rod passes through the limiting shaft and the push rod is arranged perpendicular to the limiting shaft, the starting end of the push rod is arranged near the discharge port and the starting end of the push rod is a pushing end for pushing the power ball in the ball pocket groove near the discharge port into the discharge port when the turntable rotates.

[0013] The benefit of adopting the above technical solution is that: when the turntable rotates, the push rod is always in a state of being placed in the ball pocket groove, that is, when the wrapping head with the power ball approaches the pushing end, the turntable rotates so that the push rod and the power ball touch each other. Because the push rod is in a fixed state, the power ball can be blocked by the push rod and roll into the discharge port when the turntable rotates, thereby realizing the automatic filling of the power ball into the guide pipe, thereby ensuring the circulation, replenishment and discharge of the power ball.

[0014] The utility model is further provided with: a plurality of vertical frames are detachably connected between the guide pipe and the base, the discharge port is arranged higher than the feed port, the inclined plate is inclined toward the base from the feed port to the discharge port, and the inclined plate is arranged relatively parallel to the turntable.

[0015] The benefits of adopting the above technical solution are: in the above technology, the inclined plate is tilted toward the base from the inlet to the outlet, so that the turntable forms a height difference, and then when the turntable rotates, a certain potential energy is generated, so that the power ball has a certain inertia when it moves relative to the power ball, so that the top rod can make the power ball escape from the ball pocket and fall into the outlet when it touches the power ball. At the same time, the outlet is set higher than the inlet, so that the middle section of the guide pipe is tilted, so that when the power ball flows back to the guide pipe through the outlet, the power ball has a certain power and falls back to the inlet along the downhill section of the pipe.

[0016] The utility model is further provided with: a plurality of connecting bolts are detachably connected between the inclined plate and the base.

[0017] The benefit of adopting the above technical solution is that the connection bolts are set to achieve rapid disassembly between the tilting plate and the base, so that the operator can replace tilting plates of different sizes or adjust the tilting angle between the tilting plate and the base to adapt to different rotation amplitudes and rotation trends.

[0018] The utility model is further provided with: a through hole for the fixed shaft to pass through is opened at the center of the turntable, and a bearing is connected between the inner peripheral wall of the through hole and the outer peripheral wall of the end of the fixed shaft.

[0019] The advantages of adopting the above technical solution are that the smoothness and glide of the turntable rotation can be improved by disposing the bearings, thereby preventing the turntable from getting stuck. BRIEF DESCRIPTION OF THE DRAWINGS
