Description
Technical Field
[0001] The utility model relates to the technical field of physics teaching, in particular to a force measuring device. Background Art
[0002] When an object is deformed by an external force, the force that allows the object to return to its original shape when the external force is removed is called "elastic force". Its direction is opposite to the direction of the external force that causes the object to deform. Because the deformation of an object is varied, the elastic force generated also has various forms.
[0003] After searching, the patent document publication number is CN215954603U. The utility model discloses an elastic force demonstration device for physics teaching, which relates to the technical field of physics teaching.

A fixed frame is fixedly installed on the top of the workbench, and a scale line is arranged on the front side of the fixed frame. A distance measuring assembly is fixedly installed on the top of the workbench. Through the coordinated use of the impact block, the assembly threaded rod, the threaded block and the weight block, the number of weight blocks can be added, thereby changing the overall mass during descent, thereby demonstrating the degree of deformation caused by different masses and different heights on the first spring, increasing the scope of the demonstration, and ensuring the correct demonstration conclusion. Through the coordinated use of the hollow cylinder, the second spring, the movable block, the marking pen and the marking ruler rod, the maximum distance caused by the deformation of the first spring can be measured, and the measurement data can be accurately obtained. The formula detection can be carried out through the measurement data to obtain other conclusions.

The existing device requires people to pull the rope, but since there is no fixing device at one end of the rope, when the staff pulls the rope, it is easy to cause the weight block at the other end of the rope to be out of its original position due to different forces or shaking hands, thereby affecting the accuracy of the experimental data.

[0026] Reference Figure 2 and Figure 3 The limit assembly 2 is provided with an elastic assembly 3, and the elastic assembly 3 includes second magnetic rings 31 respectively sleeved on the plurality of vertical columns 23, and the plurality of second magnetic rings 31 are respectively magnetically connected to the plurality of first magnetic rings 22, and the upper ends of the plurality of second magnetic rings 31 are fixedly connected with springs 32, and the upper ends of the plurality of springs 32 are fixedly connected with fixing rings 33, and the upper ends of the plurality of fixing rings 33 are fixedly connected with third magnetic rings 34, and the plurality of third magnetic rings 34 are respectively magnetically connected to the impact plates 24.
[0027] In actual operation, the user can directly place different second magnetic rings 31 into the first magnetic ring 22, so that the spring 32 and the fixing ring 33 can be respectively sleeved on the vertical column 23, and then the impact plate 24 is placed. With the assistance of the third magnetic ring 34, the spring 32 can be made more stable, thereby facilitating the staff to replace springs with different elastic forces, further facilitating the staff's work and indirectly improving the staff's work efficiency.
[0028] Reference Figure 1 and Figure 4 A winding assembly 4 is connected to the side wall of the base 1, one end of the sliding assembly 5 is connected to the winding assembly 4, the winding assembly 4 includes two fixed plates 41 fixedly connected to the side wall of the base 1, a winding cylinder 42 is provided between the two fixed plates 41, the winding cylinder 42 is rotatably connected to the two fixed plates 41 through two rotating shafts, one end of one of the rotating shafts passes through the side wall of the fixed plate 41 and is fixedly connected to a rotating plate 43, one of the fixed plates 41 is fixedly connected to a horizontal plate 44, and a screw 45 in contact with the rotating shaft is threaded on the horizontal plate 44.
[0029] In actual operation, the staff can rotate the rotating plate 43 so that the pull rope can be wound around the winding drum 42, thereby moving the weight block to a suitable position. After the weight block is moved to a suitable position, the staff can directly rotate the screw 45 to fix the winding drum 42, thereby avoiding the movement of the weight block.
