Abstract
Description
Technical Field
[0001] This utility model relates to the field of sprayer technology, specifically to a filling device for a sprayer's liquid storage tank. Background Technology
[0002] A sprayer is short for spraying equipment. A sprayer is a device that uses air suction to turn medicine or other liquids into a mist and spray it evenly onto other objects. It consists of a compressed air device, a thin tube, a nozzle, etc. The sprayer's liquid tank is the container used to store and hold the medicine in the sprayer. After the medicine in the sprayer's liquid tank is used up, it needs to be refilled with medicine through the filling device.
[0003] The existing injection device has the following problems: When existing injection devices are connected to the storage tank, it is usually necessary for personnel to support the delivery pipe, which leads to inconvenience in operation. Utility Model Content
[0004] The purpose of this invention is to provide a filling device for a sprayer's liquid storage tank to solve the problems mentioned in the background art.
[0005] To achieve the above objectives, the present invention adopts the following technical solution: a filling device for a sprayer storage tank, comprising a conveying pipe, a connector connected to the conveying pipe, a docking structure provided on the conveying pipe, the docking structure comprising a docking cylinder, a docking cylinder fixed on the conveying pipe, a liquid delivery pipe provided inside the docking cylinder, a gas guide pipe provided inside the docking cylinder, a first rotating plate and a second rotating plate provided on the docking cylinder, a clamping plate provided on both the first rotating plate and the second rotating plate, a handle block provided on both the first rotating plate and the second rotating plate, a rotating rod connected to the handle block, a connecting plate provided on the rotating rod, and an insertion rod connected to the connecting plate.
[0006] Preferably, the clamping plate has a central bulge when it is in its natural, unloaded state.
[0007] Preferably, the insertion rod can be inserted into the handle block on the first rotating plate.
[0008] Preferably, when the first rotating plate and the second rotating plate are rotated into the docking cylinder, there is a certain distance between the handle blocks on the first rotating plate and the second rotating plate.
[0009] Preferably, the insertion rod is fixed with an elastic clip, and the elastic clip is under force when the insertion rod is inserted into the handle block.
[0010] Preferably, the surface of the elastic card is provided with a card head.
[0011] Compared with the prior art, the beneficial effects of this utility model are: When the delivery pipe is connected to the storage tank, the docking cylinder is aligned with the storage tank. Then, the delivery pipe and the gas guide pipe are inserted into the storage tank. Next, the first and second rotating plates are rotated so that the clamping plate is pressed against the port of the storage tank. Then, the insertion rod is aligned with the handle block on the first rotating plate, thereby positioning and fixing the first and second rotating plates. The clamping plate holds the port of the storage tank, thus achieving the docking and fixing of the docking cylinder with the storage tank. Under the clamping action of the clamping plate, it can be ensured that the docking cylinder is not easily tilted after docking. The delivery pipe is docked and fixed with the storage tank through the docking structure, achieving the beneficial effect of high convenience when re-injecting the medicine into the storage tank without the need for staff to support the delivery pipe.

[0013] In the diagram: delivery pipe-1, connector-2, docking structure-3, docking cylinder-31, infusion pipe-32, air guide pipe-33, first rotating plate-34, second rotating plate-35, clamping plate-36, handle block-37, rotating rod-38, connecting plate-39, insertion rod-310, elastic clip-311, clip head-312. Detailed Implementation
[0014] To further explain the technical solution of this utility model, a detailed description is provided below through specific embodiments.
[0015] Please see Figure 1 and Figure 2 This utility model provides a filling device for a sprayer storage tank, including a conveying pipe 1, a connector 2 connected to the conveying pipe 1, the connector 2 being connected to a liquid delivery pump, and a docking structure 3 provided on the conveying pipe 1.
[0016] Specifically, the delivery pipe 1 is connected to the reservoir port of the sprayer through the docking structure 3, and the liquid delivery pump injects the liquid into the reservoir through the delivery pipe 1.
[0017] Please see Figure 3 , Figure 4 and Figure 5This utility model provides a filling device for a sprayer storage tank. The docking structure 3 includes a docking cylinder 31. The docking cylinder 31 is docked to the conveying pipe 1 and is secured with a cable tie. An infusion pipe 32 is integrally formed inside the docking cylinder 31. An air guide pipe 33 is fixed inside the docking cylinder 31 and leads to the outside of the docking cylinder 31.
[0018] A first rotating plate 34 and a second rotating plate 35 are rotatably connected to the docking cylinder 31. A clamping plate 36 is fixed on both the first rotating plate 34 and the second rotating plate 35. A handle block 37 is provided on both the first rotating plate 34 and the second rotating plate 35. A rotating rod 38 is vertically connected to the handle block 37. A connecting plate 39 is integrally formed on the rotating rod 38. An insert rod 310 is connected to the connecting plate 39.
[0019] Among them, the middle part of the clamp 36 protrudes when it is in a natural state without being stressed.
[0020] The insertion rod 310 can be inserted into the handle block 37 on the first rotating plate 34. When the first rotating plate 34 and the second rotating plate 35 are rotated into the docking cylinder 31, there is a certain gap between the handle blocks 37 on the first rotating plate 34 and the second rotating plate 35, which facilitates the gripping of the connecting plate 39. An elastic clip 311 is fixed in the insertion rod 310. When the insertion rod 310 is inserted into the handle block 37, the elastic clip 311 is under force. The surface of the elastic clip 311 is provided with a clip head 312, which has a better locking effect.
[0021] Specifically, when the delivery pipe 1 is connected to the storage tank, the docking cylinder 31 is docked with the storage tank, and then the delivery pipe 32 and the air guide pipe 33 are inserted into the storage tank. Next, the first rotating plate 34 and the second rotating plate 35 are rotated so that the clamping plate 36 is pressed onto the port of the storage tank. Then, the insertion rod 310 is docked with the handle block 37 on the first rotating plate 34, thereby positioning and fixing the first rotating plate 34 and the second rotating plate 35. The port of the storage tank is clamped by the clamping plate 36, so that the docking cylinder 31 is docked and fixed with the storage tank. Under the clamping action of the clamping plate 36, it can be ensured that the docking cylinder 31 is not easily tilted after docking. The delivery pipe 1 is docked and fixed with the storage tank through the docking structure 3, so that when the medicine is re-injected into the storage tank, no staff need to support the delivery pipe 1, which has the beneficial effect of high convenience.
[0022] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
