Description

Technical Field

[0001] The utility model belongs to the technical field of teaching instruments, and particularly relates to an inertia balance device. Background Technique

[0002] The inertia balance device uses the inertia principle of an object during the swinging process for measurement. It usually consists of a rod for hanging the object and a device capable of recording or displaying the vibration frequency. When the object swings on the balance, the inertia force will cause the balance to produce slight vibrations or deformations, and the frequency or deformation amount of these vibrations is proportional to the mass of the object.

[0003] The patent with the patent announcement number CN209625566U discloses an inertia balance device for college physics experiments, including a base. The outer wall of the base is sequentially and fixedly provided with a digital millisecond measuring instrument, a first shaft rod, and a motor. The outer wall of the top side of the digital millisecond measuring instrument is fixedly provided with a fixed rod, and the fixed rod is clamped with a photoelectric gate. The outer wall of the shaft rod is fixedly provided with an elastic plate. One end of the elastic plate close to the groove of the photoelectric gate is fixedly provided with a weight cylinder. The outer wall of the weight cylinder is symmetrically spiraled with threaded rods. One end of each threaded rod located in the inner cavity of the weight cylinder is fixedly provided with a rubber fixing piece. The end of the elastic plate is fixedly provided with a light-shielding plate. The end of the shaft rod is fixedly provided with a disc. An arc-shaped convex block is arranged on the side wall of the disc. The output end of the motor is provided with an L-shaped rod, and the end of the L-shaped rod is fixedly provided with a hollow circular block. This utility model not only avoids manually pulling the inertia plate, thereby improving the accuracy of the measurement result, but also realizes continuous measurement of the same object, improves the measurement efficiency, and at the same time improves the accuracy of the measurement result.

[0004] However, the current inertia balance device has the following problems: The shaft rod in the suspension assembly of the inertia balance device may be worn after long-term use, which may cause changes in the shape or size of the shaft rod, thereby affecting its original stability and accuracy, resulting in errors during the measurement process of the balance, and thus inaccurate measurement results. Therefore, we propose an inertia balance device. Content of the Utility Model

Lubrication can effectively reduce friction, thus slowing down the wear rate of the shaft surface, helping to maintain the original shape and dimensional stability of the shaft, and reducing shape changes caused by wear. At the same time, through the cooperation of the baffle, the inertia plate, and the shaft clamping assembly, the baffle can prevent the lubricating liquid from flowing to the clamping assembly through the inertia plate, thereby avoiding the problem that the clamping assembly is lubricated by the lubricating liquid and the weighed block it clamps slides off.

[0015] Through the provision of an application device, the cooperation of the hinge rod, the fixed block, the long rod, and the ring block enables the pressing end of the pressing member to push the fixed block to move through the hinge rod when being pressed.

[0023] In order to make the purpose and advantages of the present utility model clearer, the present utility model will be specifically described below in conjunction with embodiments. It should be understood that the following text only describes one or several specific implementation manners of the present utility model, and does not strictly limit the scope of protection of the specific claims of the present utility model.

[0024] As Figures 1-5 shown, an inertial balance device includes a base 1. A support frame 2 is fixedly connected to the bottom of the base 1. A digital millisecond measuring instrument 3 is fixedly connected to the top of the base 1. A fixed rod 4 is fixedly connected to the top of the digital millisecond measuring instrument 3. A clamping block 5 is fixedly connected to the top of the fixed rod 4. A photoelectric gate 6 is clamped to the side of the clamping block 5. A shaft rod 9 is fixedly connected to the top of the base 1. An inertial plate 10 is fixedly connected to the outer wall of the shaft rod 9. A clamping assembly 11 is arranged on the side of the inertial plate 10. A light-shielding plate is fixed to the outer wall of the clamping assembly 11. The cooperation of the light-shielding plate, the clamping assembly 11 and the inertial plate 10 can transmit signals to the digital millisecond measuring instrument 3. A ring plate 12 is fixedly connected to the top of the shaft rod 9. An anti-wear device 7 is arranged on the top of the base 1. The anti-wear device 7 includes a motor 71. The bottom of the motor 71 is fixedly connected to the top of the base 1. A rotating shaft 72 is fixedly connected to the output shaft of the motor 71. A plurality of arc-shaped blocks 73 are fixedly connected to the upper part of the outer wall of the rotating shaft 72. A semi-arc plate 74 is fixedly connected to the inner wall of the ring plate 12. An arc-shaped liquid storage tank 75 is fixedly connected to the bottom of the semi-arc plate 74. A pressing member 76 is fixedly connected to the side of the arc-shaped liquid storage tank 75. The working principle of the pressing member 76 here is similar to that of a sprayer. The pressing member 76 is composed of a pressing part and a spring pump, so as to realize reset through the elastic force of the spring pump. A hose 77 is fixedly connected to the arc surface of the arc-shaped liquid storage tank 75. One end of the hose 77 far away from the arc-shaped liquid storage tank 75 is fixedly connected to a nozzle 78. The top of the nozzle 78 is fixedly connected to the bottom of the ring plate 12. The pressing member 76 is used to control the lubricating liquid in the arc-shaped liquid storage tank 75 to be sprayed out through the nozzle 78, so as to lubricate the shaft rod 9. Lubrication can effectively reduce the friction force, thereby slowing down the wear speed of the surface of the shaft rod 9, helping to maintain the original shape and dimensional stability of the shaft rod 9, and reducing the shape change caused by wear;

[0025] A baffle 79 is fixedly connected to the bottom of the nozzle 78. The bottom of the baffle 79 is in contact with the top of the inertial plate 10. The baffle 79 can prevent the lubricating liquid from flowing to the clamping assembly 11 through the inertial plate 10, thus avoiding the problem that the weight held by the clamping assembly 11 slips due to the lubricating force of the lubricating liquid;

[0026] The pressing end of the pressing member 76 is located on the displacement track of the plurality of arc-shaped blocks 73. The shaft rod 9 is located at the nozzle of the nozzle 78;

[0027] According to the above structure, the shaft rod 9 is one of the core components of the suspension assembly. When the shaft rod 9 is used for too long, it may be worn. The wear may cause changes in the shape or size of the shaft rod 9, thereby affecting its original stability and precision, which will cause errors in the weighing process of the scale, resulting in inaccurate measurement results. Therefore, the motor 71 is started. The output shaft of the motor 71 will drive the rotating shaft 72 to rotate. The rotation of the rotating shaft 72 will drive the arc block 73 to rotate. The rotation of the arc block 73 will squeeze the pressing end of the pressing member 76, so that the lubricating liquid inside the arc-shaped liquid storage tank 75 is sprayed onto the surface of the shaft rod 9 through the hose 77 from the nozzle 78, thereby lubricating the shaft rod 9. Lubrication can effectively reduce friction, thereby slowing down the wear rate of the surface of the shaft rod 9, helping to maintain the original shape and size stability of the shaft rod 9, and reducing the shape change caused by wear. At the same time, the baffle 79 can prevent the lubricating liquid from flowing to the clamping assembly 11 through the inertia plate 10, thereby avoiding the problem that the clamping assembly 11 is lubricated by the lubricating liquid and the weighed weight clamped by it slips off.

[0028] As Figures 1-5 shown, a coating device 8 is provided at the bottom of the pressing end of the pressing member 76. The coating device 8 includes a hinge rod 81. One end of the hinge rod 81 is hinged to the bottom of the pressing end of the pressing member 76, and the other end of the hinge rod 81 is hinged with a fixed block 82. When the pressing end of the pressing member 76 is pressed, it will push the fixed block 82 to move through the hinge rod 81. The bottom of the fixed block 82 is fixedly connected with a long rod 83. The movement of the fixed block 82 will drive the long rod 83 to move. A plurality of ring blocks 84 are fixedly connected to the circumferential surface of the long rod 83. The movement of the long rod 83 will drive the ring blocks 84 to move;

[0029] The inner walls of the plurality of ring blocks 84 are in contact with the outer wall of the shaft rod 9. The plurality of ring blocks 84 are located below the nozzle 78. The plurality of ring blocks 84 will evenly coat the lubricating liquid on the surface of the shaft rod 9 to ensure that the lubricating liquid can cover the entire surface of the shaft rod 9;

[0030] The circumferential surface of the long rod 83 is in contact with the outer wall of the shaft rod 9. The long rod 83 is located below the arc-shaped liquid storage tank 75;

[0031] According to the above structure, when the pressing end of the pressing member 76 is pressed, it will push the fixed block 82 to move through the hinge rod 81. The movement of the fixed block 82 will drive the long rod 83 to move. The movement of the long rod 83 will drive the ring blocks 84 to move. The movement of the ring blocks 84 will evenly coat the lubricating liquid on the surface of the shaft rod 9 to ensure that the lubricating liquid can cover the entire surface of the shaft rod 9.

[0032] The above are only the preferred embodiments of the present utility model. It should be noted that for those of ordinary skill in the art, without departing from the principle of the present utility model, several improvements and modifications can be made, and these improvements and modifications should also be regarded as the protection scope of the present utility model.
