Description

Technical Field

[0001] This utility model relates to the field of experimental apparatus technology, and in particular to an experimental apparatus for the synthesis and decomposition of forces. Background Technology

[0002] The composition and decomposition of forces is the foundation of vector mechanics and one of the core experiments in physics teaching. Traditional experimental equipment usually includes spring balances, rubber bands, thin ropes, drawing boards, and protractors for demonstration or operation.

Second, the position of the experimental node is difficult to maintain precisely when multiple forces act simultaneously, especially when the angle between the component forces changes. The node is prone to deviating from the preset center, directly affecting the accuracy of the experiment and the verification effect of the parallelogram law, resulting in low experimental efficiency and impacting the stability and ease of use of the equipment.

[0049] This utility model provides, for example Figures 1-4 The apparatus shown is for the experiment of force composition and decomposition.

[0050] Example 1: Includes a base 100, an experimental tray 200, a slot 300, and a connector 600. The experimental tray 200 is fixed to the top of the base 100. The slot 300 is located on the top of the experimental tray 200. A circular scale 400 is provided in the middle of the experimental tray 200.

The connector 600 is sleeved on the bottom of the first pull rope 500. Multiple tension detection components 700 are installed on the bottom of the experimental tray 200. At least one tension detection component 700 uses the connector 600 to elastically pull the first pull rope 500 at multiple angles for mechanical experimental analysis, facilitating the downward pulling of the first pull rope 500 and enabling the study of forces at different angles.

[0051] The experimental disc 200 includes a disc body 201 and an arc-shaped groove 202. The disc body 201 is fixed to the top of the base 100. A slot 300 is opened on the top of the disc body 201. A vertical line is opened on the top of the disc body 201. The top of the first pull rope 500 is slidably engaged with the inner cavity of the slot 300 and pulled vertically to facilitate the connection 600 connected to the tension detection component 700 to move to the center of the circumferential scale 400. The circumferential scale 400 is opened in the middle of the disc body 201. The arc-shaped groove 202 is opened at the bottom of the disc body 201. The arc-shaped groove 202 has an arc-shaped structure with the central axis of the disc body 201. The bottom of the tension detection component 700 is installed in the inner cavity of the arc-shaped groove 202. Through multiple tension detection components 700, it is convenient to synthesize multiple forces on the vertical first pull rope 500.

[0052] The connector 600 includes a pin 601, a connecting post 602, a snap-fit ​​assembly 603, and a connecting rope 604. The two ends of the pin 601 form a connected cavity structure. The bottom of the first pull rope 500 and the top of the second pull rope 705 are both sleeved on the outer wall of the pin 601. The connecting post 602 is snapped into one end of the pin 601. Multiple snap-fit ​​assemblies 603 are respectively installed on both sides of the inner wall of the connecting post 602. The snap-fit ​​assembly 603 is movably snapped into one end of the inner cavity of the pin 601. The connecting rope 604 is installed between two opposite snap-fit ​​assemblies 603. The snap-fit ​​assembly 603 facilitates the elastic snap-fit ​​of the connecting post 602 into the inner cavity of the pin 601.

[0053] Specifically, the snap-fit ​​assembly 603 includes a snap-fit ​​block 631, a tension spring 632, and an arc rod 633. The snap-fit ​​block 631 is rotatably inserted into the side of the connecting post 602 via a pin. The snap-fit ​​block 631 is inserted into the inner wall of the pin 601. The connecting rope 604 is fixed between two opposing snap-fit ​​blocks 631. The tension spring 632 is fixed between the snap-fit ​​block 631 and the inner wall of the connecting post 602. The arc rod 633 is fixed to the outer wall of the snap-fit ​​block 631 and is sleeved in the inner cavity of the tension spring 632. The arc rod 633 and the connecting post... The inner wall of 602 is slidably inserted. The tension spring 632 has an arc-shaped structure. One end of the tension spring 632 is fixedly connected to the outer wall of the locking block 631, and the other end of the tension spring 632 is fixedly connected to one end of the connecting post 602. When the connecting post 602 is inserted into the inner cavity of the pin 601, the two locking blocks 631 are brought together to stretch the tension spring 632. When the spring extends into one end of the inner cavity of the pin 601, the locking block 631 can be locked into the inner wall of the pin 601, thereby improving the stability of the position of the connecting post 602.

[0054] Furthermore, the tension detection assembly 700 includes a positioning element 701, a screw 702, a tension sensor 703, a hook 704, and a second pull rope 705. The positioning element 701 slides within the inner cavity of the arc-shaped groove 202. The screw 702 is threadedly connected to one end of the positioning element 701. The tension sensor 703 is installed at the other end of the positioning element 701 and is used to sense tension. The hook 704 is fixed to the top of the tension sensor 703. The second pull rope 705 is sleeved on the top of the hook 704, and one end of the second pull rope 705 is movably sleeved in the middle of the connector 600. Through the tension sensing of the tension sensor 703, the magnitude of the force can be displayed on the screen.

[0055] Specifically, the positioning component 701 includes a chuck 711, a cylinder 712, a roller 713, and a threaded groove 714. Multiple chucks 711 slide on the front of the disk body 201. The chucks 711 are fixedly connected to the outer wall of the adjacent tension sensor 703. The cylinder 712 is fixed in the middle of the chuck 711. The roller 713 rotates and passes through the middle of the cylinder 712. The roller 713 is rolledly connected to the inner cavity of the arc-shaped groove 202. The threaded groove 714 is opened at one end of the cylinder 712. The screw 702 is threadedly connected to the inner cavity of the threaded groove 714. The setting of the roller 713 facilitates smooth rolling in the inner cavity of the arc-shaped groove 202, which facilitates the tension sensor 703 to be pulled at an angle on the disk body 201 with a fixed axis.

[0056] Multiple tension detection components 700 are connected by the same connector 600 for multi-angle pulling of the bottom of the first pull rope 500. When the connecting post 602 is not installed with the pin 601, the bottom of the first pull rope 500 and the top of the second pull rope 705 can be sleeved on the outer wall of the pin 601. Then, the connecting post 602 is inserted into the inner cavity of the pin 601, so that the bottom of the first pull rope 500 and the top of the second pull rope 705 can be stably positioned between the pin 601 and the connecting post 602. This allows the second pull rope 705 to elastically pull the first pull rope 500, enabling force synthesis and decomposition experiments.

[0057] Example 2: Based on Example 1, the connector 600 further includes a jacking assembly 605. The jacking assembly 605 is installed at the other end of the pin 601. The jacking assembly 605 includes a jacking post 651, a compression spring 652, and a jacking rod 653. The jacking post 651 slides through the inner cavity of the pin 601. One end of the compression spring 652 is fixed to one end of the jacking post 651, and the other end of the compression spring 652 is fixedly connected to the inner wall of the pin 601. The jacking rod 653 slides through the middle of the pin 601, and the compression spring 652 is sleeved on the outer wall of the jacking rod 653. One end of the rod 653 is fixedly connected to one end of the top post 651, and the other end of the rod 653 is inserted and locked into the outer wall of the connecting rope 604. By pressing the top post 651, the connecting rope 604 is pushed, so that the two locking blocks 631 can slide out of the inner wall of the pin 601, which facilitates the disassembly and assembly between the connecting post 602 and the pin 601, and makes it easy to connect the top of the first pull rope 500 and the second pull rope 705 to the connecting piece 600, which facilitates the disassembly and assembly between multiple 700 and 600, and realizes the pulling of 500 by different angle pulling forces.
