[0027] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and should not be construed as limiting the present invention.

[0028] The embodiments of this utility model will be described below based on its overall structure.

[0029] A vane pump with anti-offset protection structure, such asFigures 1-6 As shown, the pump includes a pump body 1. A protective plate 2 is fixedly installed at one end of the bottom of the pump body 1. Two support blocks 3 are fixedly installed on one side of the top of the protective plate 2. A rotating rod 4 is movably installed inside the support block 3. Movable rods 5 are fixedly installed on both sides of the rotating rod 4. A gear 6 is fixedly installed in the middle of the rotating rod 4. A toothed plate 7 is movably installed at one end of the top of the protective plate 2. The toothed plate 7 and the gear 6 are meshed. A connecting rod 8 is fixedly installed at one end of the toothed plate 7. Insert blocks 9 are movably installed on both sides of the top of the protective plate 2. Limiting rods 10 are fixedly installed on both sides of the insert blocks 9. A first spring 11 is sleeved on the outside of the limiting rod 10. An inclined groove 12 is opened in the middle of the insert block 9. A fixing block 13 is fixedly installed on one side of the top of the protective plate 2. A limiting post 14 is movably installed on one side of the part, and a pressing rod 16 is movably installed at one end inside the fixing block 13. A connecting plate 17 is fixedly installed at the bottom end of the pressing rod 16, and a pin 19 is fixedly installed at the bottom end of the connecting plate 17. The number of pins 19 is set in multiple groups. By adopting a multi-point insertion structure, the pin 9 and the pin 19 can provide support for the protective plate 2 and increase friction. Through multi-point insertion, multiple support points are distributed evenly, and the multi-point support effect is more stable. It will not shift when subjected to vibration, so that the vane pump can still be fixed even if the vibration is large during operation. This ensures that the water pipe will not bend when pumping water, the water supply is smoother, and the work efficiency is improved.

[0030] Please see Figure 2 , 3 A sealing plate 20 is fixedly installed at the other end of the toothed plate 7, and the sealing plate 20 cooperates with the fixing block 13. A pressing block 21 is fixedly installed on one side of the top of the movable rod 5, and the pressing block 21 cooperates with the pressing rod 16. A second spring 15 is sleeved on one side of the limiting post 14, and the limiting post 14 and the fixing block 13 are connected by the second spring 15. A slot that cooperates with the limiting post 14 is opened on one side of the fixing block 13, and a hole that cooperates with the limiting post 14 is opened in the middle of the pressing block 21. By setting the sealing plate 20, the pin 19 can be better protected and limited when not in use, improving the safety of the pin 19 and preventing accidental contact with the pin 19 during transportation.

[0031] Please see Figure 3 The bottom of the protective plate 2 has a hole for the insertion of the pin 19. The top of the connecting plate 17 has a third spring 18 installed on both sides. The connecting plate 17 and the protective plate 2 are connected by the third spring 18. The insertion hole at the bottom of the protective plate 2 can limit the downward movement of the pin 19. The pin 19 can move along a predetermined path during the downward movement to ensure that the final support point reaches the designated position.

[0032] Please see Figure 6A slider 22 is fixedly installed at one end of the bottom of the connecting rod 8, and sliding grooves that cooperate with the slider 22 are opened on both sides of the top of the protective plate 2. The connecting rod 8 and the protective plate 2 are slidably connected. By setting the slider 22, the movement of the connecting rod 8 and the toothed plate 7 can be made more stable. The toothed plate 7 and the connecting rod 8, which play a role in bearing force during the transmission process, move more smoothly. The slider 22 can limit the movement of both while reducing friction, thus ensuring more stable transmission.

[0033] Please see Figure 5 The protective plate 2 has slots on both sides of its top that mate with the insert block 9. The protective plate 2 and the insert block 9 are connected by a first spring 11. By setting the first spring 11, the insert block 9 can be automatically limited and will not occupy extra space when not in operation. At the same time, it is safer to move the vane pump.

[0034] Please see Figure 6 One end of the connecting rod 8 is set with an arc surface, and the cross section of the middle part of the inclined groove 12 is set with an inclined surface. The connecting rod 8 and the inclined groove 12 cooperate with each other. The arc surface setting of one end of the connecting rod 8 can make it easier for the connecting rod 8 to squeeze the inclined groove 12, thereby making the squeezing process smoother and reducing friction.

[0035] Please see Figure 3 The top of the fixed block 13 has slots on both sides that cooperate with the movable rod 5. One end of the extrusion block 21 is arc-shaped. The slots on both sides of the fixed block 13 facilitate the placement of the movable rod 5. When the extrusion block 21 is limited by the limiting post 14, the second spring 15 can be placed above the fixed block 5 without taking up extra space, making it easier for the operator to use.

[0036] The working principle of this utility model is as follows: When using this utility model, the user pulls the movable rod 5, causing the movable rod 5 to drive the rotating rod 4 to rotate. When the rotating rod 4 rotates, the support block 3 provides support for the rotating rod 4 and rotates inside the support block 3. When the rotating rod 4 rotates, it drives the gear 6 to rotate. At this time, the gear 6 meshes with the tooth groove on the surface of the tooth plate 7. When the gear 6 rotates, under the action of the tooth groove, the tooth plate 7 moves to one side. At the same time, the tooth plate 7 pushes the connecting rod 8 to move. The connecting rod 8 gradually contacts the inclined groove 12 on one side of the insert block 9. At this time, one end of the connecting rod 8 presses against the inclined groove 12. Under the action of the inclined groove 12, the inclined groove 12 is compressed, causing the insert block 9 to move downward. This causes the limiting rod 10 to move downwards. At this time, the first spring 11 is compressed and contracted by the insertion block 9 and the protective plate 2. At this time, the insertion block 9 is inserted into the soil. When the toothed plate 7 moves, the toothed plate 7 drives the sealing plate 20 to move to one side. When the sealing plate 20 moves, the sealing plate 20, which completely covers the fixing block 13, gradually opens the top of the fixing block 13. When the movable rod 5 rotates to a certain position, the pressing block 21 begins to press the pressing rod 16. At this time, the pressing rod 16 is pressed down by the sealing plate 20, and at the same time, the third spring 18 is stretched. Meanwhile, the connecting plate 17 moves inside the protective plate 2, and the pin 19 at the bottom of the connecting plate 17 is inserted into the soil through the insertion hole at the bottom of the protective plate 2.

[0037] Furthermore, when the extrusion block 21 extrudes the extrusion rod 16, the limiting post 14 on one side is subjected to the extrusion effect of the extrusion block 21 and moves to one side. The displacement between the limiting post 14 and the fixed block 13 drives the second spring 15 to stretch. When the hole in the middle of the extrusion block 21 contacts the limiting post 14, the limiting post 14 loses its limit. At this time, the second spring 15 resets and drives the limiting post 14 to insert into the hole in the middle of the extrusion block 21. At this time, the extrusion block 21 is fixed, thereby fixing the movable rod 5. At this time, the whole is subjected to the limiting effect. At this time, both the insert block 9 and the insert nail 19 are inserted into the soil, increasing the overall support force and friction, preventing the protective plate 2 from shifting. The water pipe is connected to the pump body 1 through the flange on the top of the pump body 1, and the water leakage is prevented by the waterproof sleeve. This is the prior art, so it will not be elaborated on here.

[0038] Furthermore, this utility model employs a multi-point insertion structure. The insertion block 9 and the pin 19 provide support for the protective plate 2 while increasing friction. Multiple insertion points distribute the support evenly, resulting in more stable multi-point support and preventing displacement during vibration. This ensures the vane pump remains fixed even under significant vibration, preventing pipe bending and ensuring smoother water pumping, thus improving work efficiency. The enclosed plate 20 provides better protection and limits the pin 19 when not in operation, enhancing its safety and preventing accidental contact during transport. The insertion holes at the bottom of the protective plate 2 limit the downward movement of the pin 19, allowing it to move along a predetermined path and ensuring all support points reach their designated positions. By setting the slider 22, the movement of the connecting rod 8 and the toothed plate 7 can be made more stable. The toothed plate 7 and the connecting rod 8, which play a role in the force during the transmission process, move more smoothly. The slider 22 can reduce friction and limit the movement of both, ensuring more stable transmission. By setting the first spring 11, the insert block 9 can be automatically limited. It will not occupy extra space when not in operation, and it will be safer when moving the vane pump. The arc surface of one end of the connecting rod 8 can make it easier for the connecting rod 8 to squeeze the inclined groove 12, so that the squeezing process is smoother and friction is reduced. The slots opened on both sides of the fixed block 13 can facilitate the placement of the movable rod 5. When the squeezing block 21 is limited by the limiting post 14, the second spring 15 can be placed on the fixed block 5 without occupying extra space, making it easier for the operator to use.
