Moreover, the specific features, structures, materials or characteristics described may be combined in an appropriate manner in any one or more embodiments or examples.
[0038] As a specific implementation method, Figure 1-5 As shown, this embodiment provides a self-assembled spring balance experimental device, including a spring balance body 1, the spring balance body 1 includes: a writing board 2, a through hole 3 is arranged above the writing board 2, and a control ring 4 is arranged to lock the through hole 3;
[0039] A hollow groove 5 is provided in the center of the writing board 2, and the length direction of the hollow groove 5 is consistent with the length direction of the writing board 2;
[0040] A fixing column 6 connected to the writing board 2 is arranged between the hollow groove 5 and the through hole 3, and the fixing column 6 is connected to the tension ring 7; the side of the tension ring 7 away from the fixing column 6 is connected to one end of the tension spring 8; a circular chuck 9 is arranged at the other end of the tension spring 8 away from the tension ring 7; the cylinder formed by the circular chuck 9 and the tension spring 8 is on the same axis; a hook is connected to the center of the bottom surface of the circular chuck 9; the hook includes a hook column 10 connected to the bottom surface of the circular chuck 9 and a hook head 11 connected to the other end of the hook column 10; a pointer 12 is arranged in the middle part of the hook column 10, and the pointer 12 points to the writing board 2 located on both sides of the hollow groove 5, and the length of the pointer 12 extends to the upper surface of the writing board 2.
[0041] Furthermore, the writing board 2 is perpendicular to the length direction of the hook column 10; the pointer 12 includes a bidirectional pointer 12 and a unidirectional pointer 12, and the pointer 12 is a bidirectional pointer 12 in this embodiment.
[0042] In the specific use process, the spring balance body 1 is placed vertically, and a certain force is applied to the hook head 11 (or the object to be measured is hung on the hook head 11, and the pointer 12 moves along the gravity direction under the action of gravity); at this time, the tension spring 8 undergoes vertical deformation in the hollow groove 5, and the upper end of the tension spring 8 is fixed by the fixing column 6 connected by the tension ring 7 (the tension ring 7 plays a role in the spatial transition between the fixing column 6 and the tension spring 8). After deformation, the hanging circular chuck 9 connected to the other end of the tension spring 8 and the hook connected to the circular chuck 9 move in the deformation direction of the tension spring 8, and the pointer 12 on the hook column 10 also moves accordingly, and finally stops at a certain place. At this time, the position indicated by the pointer 12 represents the force applied. Students can mark the corresponding scale on the wooden writing board 2 of the device according to the law of exploration; due to the large amplitude of the wooden writing board 2, the corresponding knowledge and the relevant laws of spring elastic force can be written on it, which is easy to check or understand by others.
[0043] Optionally, the length of the hollow groove 5 is 4 / 7-6 / 7 of the length of the writing board 2; the width is 1 / 3-2 / 5 of the width of the writing board 2; and the thickness of the writing board 2 is 0.3-1.5 cm. In this case, the space of the hollow groove 5 can provide a sufficient deformation and stretching space for the tension spring 8, and the area of the writing board 2 can be ensured to be sufficient for students to write corresponding knowledge and relevant laws of spring elastic force, which is easy to check or for others to understand.
[0044] Optional, such as Figure 2-3 As shown, the control ring 4 includes a first ring segment 13 and a second ring segment 14; the connection between the head end of the first ring segment 13 and the tail end of the second ring segment 14 is the first connection point 15 of the control ring; the connection between the head end of the second ring segment 14 and the tail end of the first ring segment 13 is the second connection point 16 of the control ring.
[0045] Furthermore, the outer side of the first connection point 15 of the control ring is fixedly connected, and the inner side is connected by snap connection;
[0046] The first connection point 15 of the control ring is connected by hinge; the tail end of the first ring segment 13 is fixedly provided with a tethering column 17 that passes through the control ring 4, and the head end of the second ring segment 14 is provided with a tethering hole 18 that cooperates with the tethering column 17, and the connection between the head end of the second ring segment 14 and the tail end of the first ring segment 13 is achieved through the cooperation of the tethering column 17 and the tethering hole 18.
[0047] In this way, the spring balance can be placed better when idle. When it is hung for use, first pull out the tail end of the first ring section 13 with the tie column 17 that penetrates the control ring 4 at the second connection point 16 of the control ring. At this time, the tie column 17 is separated from the tie hole 18. Under the action of the pulling force, the inner side of the head end of the first ring section 13 located at the first connection point is pulled inward and separated from the inner side of the tail end of the second ring section 14; in this way, the control ring 4 is opened, and after it is hung, it is closed in the opposite order. In this way, the control ring 4 can be ensured to be stable when closed and can be hung under different conditions, which is very convenient and solves the high requirements and difficulties of traditional spring balances when placed.
[0048] Optionally, the length of the tension spring 8 is 1 / 5-1 / 4 of the length of the hollow groove 5. At this time, in a static state, the force on the spring is 0. At this time, the sufficient deformation length of the spring can be guaranteed.
[0049] Optional, such as Figure 5 As shown, the circular chuck 9 and the hook column 10 are connected by threads. Specifically, an adjustment hole is set in the center of the circular chuck 9, and a convex thread is set on the side of the adjustment hole; the part of the hook column 10 that contacts the adjustment hole is provided with a concave thread that matches the convex thread, and the length of the hook column 10 outside the circular chuck 9 is adjusted by rotating the thread. When in use, it can be adjusted to the optimal length according to the situation.
[0050] Optionally, a groove 19 matching the edge of the writing board 2 is symmetrically arranged around the periphery of the circular chuck 9 .
[0051] Furthermore, the diameter of the columnar body formed by the spring is smaller than the width of the hollow groove 5; the diameter of the circular chuck 9 is larger than the width of the hollow groove 5; and the distance between the bottoms of the two centrally symmetrically arranged grooves 19 is smaller than the width of the hollow groove 5. In this way, during use, the circular chuck 9 plays a role in connecting the hook and the spring on the one hand; on the other hand, the groove 19 provided around the chuck matches the edge of the writing board 2, which plays a role in limiting the spring during the force-bearing process.
[0052] Optionally, the length of the hook column 10 is 1 / 5-1 / 3 of the length of the hollow groove 5 , which refers to the length of the hook column 10 between the bottom surface of the circular chuck 9 and the hook head 11 .
[0053] Optionally, the material of the pointer 12 includes plastic;
[0054] Optionally, the connection modes of the fixing column 6 and the tension ring 7 include fixed connection, clamping connection and through connection.
[0055] Optionally, the corners of the writing board 2 are arc-shaped. The top and bottom surfaces of the hollow groove 5 are both arc-shaped to accommodate the arc-shaped hook head 11, which is more convenient.
[0056] Optional, such as Figure 4 As shown, the tip of the pointer 12 is arc-shaped; a scale line is set in the center of the upper surface of the pointer 12 in the same direction as the pointer 12. The arc shape is to avoid poking students; because students are more irritable and tender, they are easily injured. The scale line can overcome the problem of unclear scale caused by the arc-shaped tip pointer 12.
[0057] Each embodiment in this specification is described in a progressive manner, and the same or similar parts between the embodiments can be referred to each other, and each embodiment focuses on the differences from other embodiments. In particular, for the system embodiment, since it is basically similar to the method embodiment, the description is relatively simple, and the relevant parts can be referred to the partial description of the method embodiment.
[0058] The above is only an embodiment of the present application and is not intended to limit the present application. For those skilled in the art, the present application may have various changes and variations. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present application should be included in the scope of the claims of the present application.
