[0001] This utility model relates to the field of gear pump technology, specifically a gear pump that is easy to disassemble and assemble. Background Technology
[0002] A gear pump consists of two gears, a pump body, and a cover plate, forming two enclosed spaces. When the gears rotate, the volume of the space on the disengaged side increases from small to large, creating a vacuum that draws in liquid; the volume of the space on the meshing side decreases from large to small, squeezing the liquid into the pipeline. The suction chamber and the discharge chamber are separated by the meshing line of the two gears.
[0003] In the existing technology, the cover plate of the gear pump is usually fastened by multiple sets of bolts. During the fixing process, the cover plate needs to be rotated one set at a time to complete the installation. The installation is time-consuming and cumbersome. Therefore, we propose a gear pump that is easy to disassemble and assemble. Utility Model Content

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0020] Example 1
[0021] Please refer to Figure 1-3 As shown, this utility model provides a gear pump that is easy to assemble and disassemble, including a pump housing 1. One side of the pump housing 1 is sealed by a baffle 2. The other side of the pump housing 1 is provided with an adjustment component that can lock the baffle 2. The adjustment component includes a limit seat 3, a slider 4, a screw 5, a first motor 6, and a limit frame 7. The limit seat 3 is installed on one side of the baffle 2. A set of slidable sliders 4 is provided at each end of the inner cavity of the limit seat 3. The two sets of sliders 4 are threadedly connected to two sets of screws 5 respectively. The threads of the two sets of screws 5 are opposite and are respectively connected to two sets of output shafts of the first motor 6. A set of limit frames 7 is installed at the opposite ends of the two sets of sliders 4. The two sets of limit frames 7 are mirror images of each other and can penetrate the pump housing 1 to be inserted into the baffle 2 to lock it.
[0022] In this embodiment, the first motor 6 is specifically a dual-output shaft motor. By starting the first motor 6, two sets of screws 5 with opposite threads are driven to rotate, causing the two sets of sliders 4 connected to them to slide along the inner cavity of the limiting seat 3. The distance between the two sets of sliders 4 can be adjusted, thereby adjusting the distance between the two sets of limiting frames 7. The limiting frame 7 can be inserted through the pump housing 1 and locked to the baffle 2, so that the baffle 2 seals the pump housing 1. Compared with the prior art, the baffle 2 is faster to disassemble and is easier to disassemble and assemble.
[0023] Please refer to Figure 1-3As shown, a slot 8 that matches the baffle 2 is provided on one side of the pump housing 1. A sealing element 9 is provided on one side of the slot 8. The sealing element 9 can seal the gap between the pump housing 1 and the slot 8. Two sets of rotatable first gears 10 are installed in the inner cavity of the pump housing 1, and the two sets of first gears 10 mesh with each other. One set of first gears 10 is rotated by a drive assembly. The drive assembly includes a second gear 11, a third gear 12 and a second motor 13. One set of first gears 10 penetrates the pump housing 1 and connects to the second gear 11. The second gear 11 meshes with the third gear 12. The third gear 12 is connected to the output end of the second motor 13.
[0024] In this embodiment, by starting the second motor 13, the third gear 12 is driven to rotate, causing the second gear 11 meshing with it to rotate, which in turn drives a set of first gears 10 connected to it to rotate, causing another set of first gears 10 to rotate. The installed sealing element 9 can seal the gap between the pump housing 1 and the slot 8, thereby achieving the sealing of the pump housing 1.
[0025] Please refer to Figure 1-3 As shown, the drive assembly is covered by a protective shell 14, which is connected to the pump housing 1. The pump housing 1 and the bottom of the protective shell 14 are connected to a base 15. A set of water pipes 16 are installed on both sides of the pump housing 1 at the meshing positions of the two sets of first gears 10. One set of water pipes 16 is used for water inlet, and the other set of water pipes 16 is used for water outlet.
[0026] In this embodiment, the protective shell 14 can protect the drive assembly, and the base 15 can provide stable support for the pump housing 1. A set of water pipes 16 are installed on each side of the pump housing 1 at the meshing position of the two sets of first gears 10. One set of water pipes 16 is used for water inlet, and the other set of water pipes 16 is used for water outlet. When the two sets of first gears 10 rotate, the volume of the space on the disengaged side of the first gear 10 increases from small to large, forming a vacuum and drawing in the liquid; the volume of the space on the meshing side of the first gear 10 decreases from large to small, squeezing the liquid into the pipe. The suction chamber and the discharge chamber are separated by the meshing line of the two first gears 10.
[0027] Working principle: First, by starting the first motor 6, the two sets of screws 5 with opposite threads are driven to rotate, causing the two sets of sliders 4 connected to them to slide along the inner cavity of the limiting seat 3. The distance between the two sets of sliders 4 can be adjusted, thereby adjusting the distance between the two sets of limiting frames 7. The limiting frame 7 can be inserted through the pump housing 1 and locked to the baffle 2, so that the baffle 2 seals the pump housing 1. Compared with the prior art, the baffle 2 is quicker and easier to disassemble and assemble. By starting the second motor 13, the third gear 12 is driven to rotate, causing the second gear 11 meshing with it to rotate. The first gear 10 connected to it rotates, causing the other first gear 10 to rotate. When the two sets of first gears 10 rotate, the volume of the space on the disengaged side of the first gear 10 increases from small to large, forming a vacuum and drawing in the liquid; the volume of the space on the meshing side of the first gear 10 decreases from large to small, squeezing the liquid into the pipeline. The suction chamber and the discharge chamber are separated by the meshing line of the two first gears 10. A set of water pipes 16 are installed on each side of the pump housing 1 at the meshing position of the two sets of first gears 10. One set of water pipes 16 is used for water inlet, and the other set of water pipes 16 is used for water outlet.
