[0024] The specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are for illustration and explanation only and are not intended to limit the scope of this utility model.

[0025] In this utility model, unless otherwise stated, directional words such as "upper," "lower," "inner," and "outer" included in the terminology only represent the orientation of the term in its conventional use or are common terms understood by those skilled in the art, and should not be regarded as limitations on the term.

[0026] like Figure 1-6 As shown, a foldable quick-release nozzle for a drone includes: a foldable support tube and a flexible hose 1 mounted on the foldable support tube. The two ends of the flexible hose 1 are respectively fixedly mounted on the two ends of the foldable support tube. The foldable support tube includes at least two sections of branch pipe 2 connected by a connecting mechanism.

[0027] In the above technical solution, before cleaning the high altitude, the cleaning equipment needs to be assembled. The folded support tube is opened and the two adjacent branch tubes 2 are fixed by the connecting mechanism. When in use, one end of the hose 1 is connected to the nozzle and the other end is connected to the water supply pipe. The folded support tube is not only easy to carry, but also easy to unfold, which can improve the work efficiency during assembly. When folding, the hose 1 and the folded support tube cooperate to bend.

[0028] In a preferred embodiment of this utility model, both ends of the hose 1 are equipped with connectors 3, and the branch pipe 2 is movably equipped with a limiting sleeve 4 that can move on the hose 1.

[0029] In the above technical solution, the connector 3 can be a commonly used movable connector in the field, which not only facilitates various types of nozzles, but also facilitates the quick connection of the other end of the hose 1 to the water supply pipe.

[0030] The drone sprays water from the ground to the nozzles at high altitudes, requiring corresponding water pressure. Therefore, the hose 1 also needs to have corresponding pressure resistance. When the hose 1 has high pressure resistance, its performance will affect the minimum bending radius when it is bent. Therefore, a movable limiting sleeve 4 is set. When it is unfolded for use, it can restrain the hose 1. When unfolded, the limiting sleeve 4 can be moved away from the connecting mechanism to increase the bending radius of the hose 1, protect the hose 1, and improve the service life of the hose 1.

[0031] In a preferred embodiment of the present invention, a convex-shaped locking block 5 is fixedly mounted on the drone frame, and a quick-release mechanism that can be detachably connected to the convex-shaped locking block 5 is mounted on one end of the folding support tube.

[0032] In the above technical solution, the U-shaped locking block 5 can be assembled onto the drone frame by bolts or welding. During assembly, the quick-release mechanism can be assembled onto the U-shaped locking block 5 to quickly complete the assembly and improve the efficiency of the assembly work.

[0033] In a preferred embodiment of the present invention, the connecting mechanism includes a first connecting member 6 fixedly connected to the end of the branch pipe 2 and a second connecting member 7 hinged to the first connecting member 6 and connected to the end of the adjacent branch pipe 2. The first connecting member 6 is equipped with a plug rod 8 that can be detachably engaged with the second connecting member 7.

[0034] In the above technical solution, when it is necessary to unfold the folding support tube, the two adjacent branch tubes 2 are rotated around the hinge of the first connector 6 and the second connector 7 so that the first connector 6 and the second connector 7 abut against each other, and then the first connector 6 and the second connector 7 are connected together by the insertion rod 8.

[0035] When folding and storage are required, the control rod 8 allows the first connector 6 and the second connector 7 to rotate around the hinge, so that the two adjacent tubes 2 are folded into a parallel state.

[0036] In a preferred embodiment of the present invention, the insertion rod 8 is slidably mounted on the first connecting member 6 along its own length direction, a snap-fit ​​rod 9 is fixedly connected to the insertion rod 8, a snap-fit ​​part 10 matching the snap-fit ​​rod 9 is mounted on the second connecting member 7, and an auxiliary spring 11 is provided on the insertion rod 8.

[0037] In the above technical solution, when the first connector 6 and the second connector 7 are in contact, the locking rod 9 will engage with the locking part 10; when separating, the control rod 8 drives the locking rod 9 to separate from the locking part 10, and then the first connector 6 or the second connector 7 is rotated. The function of the auxiliary spring 11 is to push the locking rod 9 to engage with the locking part, so as to prevent the two from separating during use.

[0038] In a preferred embodiment of the present invention, one end of the insertion rod 8 slides outward through the first connector 6 and a button portion 12 protrudes from the end. The two ends of the auxiliary spring 11 respectively abut against the button portion 12 and the first connector 6. A strip-shaped through groove 13 is provided through the first connector 6 for the end of the locking rod 9 to slide into.

[0039] In the above technical solution, when separating, pressing the button part 12 causes the insertion rod 8 to drive the locking rod 9 to separate from the locking part 10; releasing the button causes the auxiliary spring 11 to drive the insertion rod 8 to slide back to its original position, and the end of the locking rod 9 slides in the strip groove, which plays a limiting role and prevents the insertion rod 8 from slipping off the first connector 6.

[0040] In a preferred embodiment of the present invention, the quick-release mechanism includes a sleeve 14 fixedly mounted on the end of the folding support tube and matching the U-shaped locking block 5. A spring pin 15 is mounted on the sleeve 14, and the U-shaped locking block 5 is recessed with a hole matching the spring pin 15.

[0041] In the above technical solution, the spring pin 15 is an existing mature technology, and its structure and working principle will not be described in this article. The sleeve 14 is placed on the convex-shaped card block 5, and the end of the spring pin 15 is inserted into the corresponding hole, so that the sleeve 14 can be assembled on the convex-shaped card block 5.

[0042] In a preferred embodiment of the present invention, one side of one end of the sleeve 14 is a slidable clamping block 16, and the sleeve 14 is equipped with a quick-pressing cam screw buckle 17 that can press and hold the clamping block 16.

[0043] In the above technical solution, the quick-press cam screw clip 17 is an existing mature technology. Its structure and working principle will not be described in this article. The quick-press cam screw clip 17 presses the cam onto the clamping block 16 so that the clamping block 16 is tightly pressed onto the convex-shaped pressure block, thereby improving the stability and firmness of the connection between the sleeve 14 and the convex-shaped clamping block 5.

[0044] The preferred embodiments of the present invention have been described in detail above with reference to the accompanying drawings. However, the present invention is not limited to the specific details of the above embodiments. Within the scope of the technical concept of the present invention, various simple modifications can be made to the technical solution of the present invention, and these simple modifications all fall within the protection scope of the present invention.

[0045] It should also be noted that the various specific technical features described in the above specific embodiments can be combined in any suitable way without contradiction. In order to avoid unnecessary repetition, this utility model will not describe the various possible combinations separately.

[0046] Furthermore, various different embodiments of this utility model can be combined in any way, as long as they do not violate the spirit of this utility model, they should also be regarded as the content disclosed by this utility model.
