Description
Technical Field
[0001] This utility model relates to the field of scientific educational toys, specifically a detachable linkage water pump device for scientific educational toys. Background Technology
[0002] In the fields of science education and children's toys, interactivity and hands-on experience are key factors in enhancing learning interest and depth of understanding. This is especially true for the pumping principle in physics, a crucial component of fluid mechanics and mechanical principles, which is significant for cultivating students' practical skills and scientific thinking.
[0003] Traditional scientific teaching aids for water pumps often focus on demonstration rather than interaction. Students can only observe and cannot directly participate in the operation. Although this teaching method can transmit knowledge to a certain extent, it lacks interactivity and practicality, making it difficult to stimulate students' learning interest and desire for exploration. To a certain extent, it limits students' in-depth understanding and experience of the principles of water pumping. Therefore, a detachable and interconnected scientific teaching aid for water pumps is proposed to solve the above problems. Utility Model Content
[0004] To address the shortcomings of existing technologies, this invention provides a detachable linkage pumping device as a scientific educational toy, thereby overcoming the deficiencies in the aforementioned existing technologies.
[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows:
[0006] A detachable linkage water pump device is a scientific teaching aid, including a base plate, on the top of which is equipped with a manual water pumping mechanism;
[0007] The manual water pumping mechanism includes a horizontal cylinder fixedly installed on the top of the base plate. A vertical cylinder, which is interconnected with the horizontal cylinder, is fixedly installed on the top of the horizontal cylinder. A piston is slidably installed inside the vertical cylinder. A connecting rod structure for controlling the piston's lifting and lowering is provided on the top of the piston. Connecting cylinders penetrating the horizontal cylinder are threaded onto both the left and right sides of the horizontal cylinder. A water suction pipe is fixedly installed on the left side of the left connecting cylinder. A first bracket, located near the left side of the horizontal cylinder, is fixedly installed inside the first bracket. A first horizontal rod is slidably installed inside the first bracket. A circular ring plate A is fixedly installed inside the left connecting cylinder. A penetrating ring plate A is fixedly installed on the left side of the first horizontal rod. Inside component A, there is a sealing truncated cone a. A left return spring is movably installed on the outside of the first crossbar, located between the sealing truncated cone a and the first bracket. A drain pipe is fixedly installed on the right side of the connecting cylinder on the right side. A second bracket is fixedly installed inside the connecting cylinder on the right side. A second crossbar is slidably installed inside the second bracket. A circular ring plate B is fixedly installed inside the connecting cylinder on the right side, near its left side. A sealing truncated cone b, penetrating into the circular ring plate B, is fixedly installed on the left side of the second crossbar. A right return spring is movably installed on the outside of the second crossbar, located between the second bracket and the sealing truncated cone b.
[0008] The beneficial effects of this utility model are as follows: When the piston rises to draw air from the horizontal cylinder, the annular plate B and the sealing truncated cone b seal the connecting cylinder. The sealing truncated cone a moves to the right under pressure, and the interior of the annular plate A loses its seal, generating suction in the pumping pipe. When the piston descends to compress the air in the horizontal cylinder, the sealing truncated cone a seals the annular plate A. At the same time, the sealing truncated cone b moves to the right under pressure, and the interior of the annular plate B loses its seal, allowing the gas to be discharged. When students operate the piston to rise and fall, they can intuitively understand the operating principle of the pumping mechanism.
[0009] Based on the above technical solution, the present invention can be further improved as follows.
[0010] Furthermore, the connecting rod structure includes a support plate fixedly installed on the top of the base plate, a rotating plate rotatably installed on the front of the support plate near its top, a rotating wheel fixedly installed on the back of the rotating plate located on the back of the support plate, a first connecting rod rotatably installed on the surface of the rotating plate near its bottom, a second connecting rod rotatably installed at the bottom of the first connecting rod, and the second connecting rod fixedly installed on the top of the piston.
[0011] Furthermore, an acrylic water cylinder is fixedly installed on the top of the base plate, and both the water suction pipe and the water drain pipe penetrate into the interior of the acrylic water cylinder.
[0012] Furthermore, both the sealing frustum a and the sealing frustum b are fixedly installed with sliding blocks that penetrate into the interior of the two connecting cylinders, and the two sliding blocks are respectively slidably installed inside the two connecting cylinders.
[0013] Furthermore, limit rods are fixedly installed on the bottom of the inner walls of both connecting cylinders, and the two sliding blocks are slidably installed on the outside of the two limit rods respectively.
[0014] Furthermore, the height of the support plate is greater than the height of the vertical cylinder. Attached Figure Description

[0023] The principles and features of this utility model are described below with reference to the accompanying drawings. The examples given are only for explaining this utility model and are not intended to limit the scope of this utility model.
[0024] Example 1, as Figures 1-4 As shown, a detachable linkage water pump device is a scientific teaching aid, including a base plate 1, and a manual water pumping mechanism is provided on the top of the base plate 1.
[0025] Specifically, the manual water pumping mechanism includes a horizontal cylinder 2 fixedly installed on the top of the base plate 1. A vertical cylinder 3, which is connected to the horizontal cylinder 2, is fixedly installed on the top of the horizontal cylinder 2. A piston 4 is slidably installed inside the vertical cylinder 3. A connecting rod structure for controlling the lifting and lowering of the piston 4 is provided on the top of the piston 4. Connecting cylinders 5, which penetrate into the horizontal cylinder 2, are threadedly installed on both the left and right sides of the horizontal cylinder 2. A water pumping pipe 6 is fixedly installed on the left side of the left connecting cylinder 5. A first bracket 7, located near the left side of the horizontal cylinder 2, is fixedly installed inside the first bracket 7. A first horizontal rod 8 is slidably installed inside the first bracket 7. A circular ring plate A9 is fixedly installed inside the left connecting cylinder 5. A sealing truncated cone, which penetrates into the circular ring plate A9, is fixedly installed on the left side of the first horizontal rod 8. A left return spring 11 is movably installed on the outside of the first crossbar 8 (a10). The left return spring 11 is located between the sealing frustum a10 and the first bracket 7. A drain pipe 12 is fixedly installed on the right side of the right connecting cylinder 5. A second bracket 13 is fixedly installed inside the right connecting cylinder 5. A second crossbar 14 is slidably installed inside the second bracket 13. A circular ring plate B15 is fixedly installed inside the right connecting cylinder 5 near its left side. A sealing frustum b16, penetrating into the circular ring plate B15, is fixedly installed on the left side of the second crossbar 14. A right return spring 17 is movably installed on the outside of the second crossbar 14. The right return spring 17 is located between the second bracket 13 and the sealing frustum b16.
[0026] When the right return spring 17 unfolds, it can push the sealing platform b16 to move into the annular plate B15. When the left return spring 11 unfolds, it can push the sealing platform a10 to move into the annular plate A9. When the piston 4 rises, it will draw air from the inside of the horizontal cylinder 2. At this time, the connecting cylinder 5 on the right side is blocked by the annular plate B15 and the sealing platform b16, and the air cannot flow. Under pressure, the sealing platform a10 inside the annular plate A9 moves to the right. At this time, the inside of the annular plate A9 is unblocked, so that the water pipe 6 can generate suction. When the piston 4 falls, it will squeeze the air inside the horizontal cylinder 2, and then push the sealing platform a10 to block the annular plate A9. At this time, the pressure inside the horizontal cylinder 2 will push the sealing platform b16 to move to the right. At this time, the inside of the annular plate B15 is unblocked, and the gas can be discharged outward through the annular plate B15 and the drain pipe 12. While controlling the piston 4 to rise and fall, students can clearly and intuitively understand the operating principle of the pump mechanism.
[0027] It should be noted that the horizontal cylinder 2, the vertical cylinder 3, and the two connecting cylinders 5 are all made of acrylic.
[0028] Example 2, as Figures 1-4 As shown, this embodiment is a further improvement based on embodiment 1, and its specific details are as follows:
[0029] The linkage structure includes a support plate 18 fixedly installed on the top of the base plate 1, a rotating plate 19 rotatably installed on the front of the support plate 18 near its top, a rotating wheel 20 fixedly installed on the back of the rotating plate 19 located on the back of the support plate 18, a first connecting rod 21 rotatably installed on the surface of the rotating plate 19 near its bottom, a second connecting rod 22 rotatably installed at the bottom of the first connecting rod 21, and the second connecting rod 22 fixedly installed on the top of the piston 4.
[0030] With this configuration, the rotating plate 19 is supported above the base plate 1 by the support plate 18. The rotating plate 19 can be rotated by holding the rotating wheel 20. In the rotating state, the rotating plate 19 can drive the second connecting rod 22 and the piston 4 to make linear reciprocating motion inside the vertical cylinder 3 through the 31.
[0031] Example 3, as Figures 1-2 As shown, this embodiment is a further improvement based on embodiment 1, and its specific details are as follows:
[0032] An acrylic water cylinder 23 is fixedly installed on the top of the base plate 1, and the water pumping pipe 6 and the drain pipe 12 both penetrate into the interior of the acrylic water cylinder 23.
[0033] With this setup, when the suction pipe 6 generates suction, it can draw water from inside the acrylic water cylinder 23. Then, the water enters the interior of the horizontal cylinder 2 and passes through the connecting cylinder 5 and the drain pipe 12 to be discharged into the interior of the acrylic water cylinder 23, thus forming a water cycle. This achieves the goal of saving water while teaching.
[0034] Example 4, as Figure 3 and Figure 6 As shown, this embodiment is a further improvement based on embodiment 1, and its specific details are as follows:
[0035] Both the sealing frustum a10 and the sealing frustum b16 have sliding blocks 24 fixedly installed at their bottoms, which penetrate into the interior of the two connecting cylinders 5. The two sliding blocks 24 are slidably installed inside the two connecting cylinders 5 respectively.
[0036] With this configuration, the sealing frustum a10 and sealing frustum b16 are supported and slid inside the two connecting cylinders 5 by the two sliding blocks 24 respectively, so that the sealing frustum a10 and sealing frustum b16 can be accurately reset when moving.
[0037] Example 5, as Figure 3 and Figure 6 As shown, this embodiment is a further improvement based on embodiment 4, and its specific details are as follows:
[0038] Limiting rods 25 are fixedly installed on the bottom of the inner walls of the two connecting cylinders 5, and two sliding blocks 24 are slidably installed on the outside of the two limiting rods 25 respectively.
[0039] This configuration, with two limiting rods 25 respectively, restricts the two sliding blocks 24 inside the two connecting cylinders 5, making the sealing frustum a10 and sealing frustum b16 more stable during sliding.
[0040] Example 6, as Figures 1-2 As shown, this embodiment is a further improvement based on embodiment 2, and its specific details are as follows:
[0041] The height of the support plate 18 is greater than the height of the vertical cylinder 3.
[0042] With this setup, the rotating plate 19 is supported above the vertical cylinder 3 by the support plate 18 for stable output.
[0043] Although embodiments of the present invention have been shown and described above, it is understood that the above embodiments are exemplary and should not be construed as limiting the present invention. Those skilled in the art can make changes, modifications, substitutions and variations to the above embodiments within the scope of the present invention.
