[0002] Municipal engineering refers to municipal infrastructure construction projects. Landscaping is a type of municipal engineering. It is a beautiful natural environment and recreational space created by using engineering technology and artistic means in a certain area, through transforming the terrain (or further building mountains, stacking stones, and managing water), planting trees and flowers, creating buildings, and arranging garden paths. Sprinklers are commonly used equipment in landscaping.

[0003] According to the Chinese utility model disclosure number CN212520269U, an intelligent municipal garden greening spray device includes a water outlet pipe, and the top of the water outlet pipe is movably connected to the spray device body. By setting a slot, a moving rod, a moving plate, a limit block and a limit slot, the user can rotate the rotating rod, the rotating rod rotates on the rotating shaft, pulls the moving rod to move, the moving rod drives the moving plate to move, the moving plate drives the limit block to enter the fixed shell, the moving plate drives the first spring to deform under force, the fixed shell rotates and snaps into the slot, releases the moving rod, and the moving rod drives the limit block to snap into the limit slot, which solves the problem that the existing garden greening spray devices are mostly threaded and the spray devices are prone to clogging. The user needs to replace the spray, and frequent replacements are prone to damage to the internal threads, causing the phenomenon of thread slippage, and the spray cannot be sprayed evenly, which increases the difficulty of operation for the user. This is worth promoting.

[0004] Most gardening sprinkler devices are thread-locked, and the sprinkler devices are prone to clogging. Users need to replace the sprinkler, and frequent replacements can easily damage the internal threads and cause thread stripping. When replacing the sprinkler device, the above disclosure requires first pulling the positioning rod, and then pulling the limit rod downward to release the restriction on one side. When disassembling the entire sprinkler device, the operation needs to be repeated twice, which is relatively complicated and is not convenient for improving the efficiency of disassembling the sprinkler device.

[0041] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0042] Embodiment 1

[0043] See also Figure 1-4 A municipal gardening and greening spraying device comprises a main body component 1, wherein the main body component 1 comprises: a spray box 11, on which a connecting pipe 12 is connected through; a spray head 13, which is movably connected to the right end of the connecting pipe 12; a connecting component 2 is arranged on the connecting pipe 12 and the spray head 13, and the connecting component 2 comprises: a connecting block 21, which is arranged outside the spray head 13; a blind hole 22, which is symmetrically opened on the connecting block 21; a frame 23, which is arranged outside the connecting pipe 12; a spring 24, which is symmetrically arranged on the inner wall of the frame 23; a movable plate 25, which is symmetrically arranged at the opposite end of the spring 24, and the two ends of the movable plate 25 extend out of the frame 23; a fixed block 26, which is symmetrically arranged on the opposite surface of the movable plate 25, and the fixed block 26 is used in conjunction with the blind hole 22; a driving mechanism 27, which is symmetrically arranged on the frame 23 and the spring 24. The driving mechanism 27 includes: a spring 271 symmetrically arranged on the outer wall of the frame 23; a pressure rod 272 arranged on the end of the spring 271 away from the frame 23; a pressure plate 273 arranged on the end of the pressure rod 272 away from the spring 271; a connecting rod 274 symmetrically hinged on the outer wall of the pressure rod 272; a push block 275 symmetrically rotationally connected to the end of the connecting rod 274 away from the pressure rod 272; a dovetail block 276 arranged on the outer wall of the push block 275; a dovetail groove 277 symmetrically opened on the outer wall of the frame 23, and the dovetail block 276 is slidably connected to the dovetail block 276. A telescopic rod 4 is fixedly connected between the frame 23 and the pressure rod 272, and the spring 271 is sleeved on the outside of the telescopic rod 4.

[0044] When in use, the staff adds water to the spray box 11, uses a trolley to move the spray box 11, and the spray head 13 sprays water to spray the greenery in the circular forest. When the spray head 13 is blocked and needs to be replaced, the staff uses the connecting component 2 to conveniently disassemble and replace it: when the spray head 13 is connected to the connecting pipe 12, the fixing block 26 enters the blind hole 22 to fix the spray head 13. When it needs to be disassembled, the pressure plates 273 on both sides are pressed at the same time, and the pressure plate 273 drives the pressure rod 272 to compress the spring 271, and the connecting rod 274 hinged at two places is linked to push the push block 275 at the same time, and the dovetail block 276 on the push block 275 slides in the dovetail groove 277, and the push block 275 moves outward. When the spring 271 is moved, the two movable plates 25 are driven to separate from each other, and the spring 1 24 is compressed, and the fixed block 26 is separated from the blind hole 22 at the same time, and the restriction on the connection block 21 is released. At this time, the connection block 21 and the sprinkler head 13 can be removed together. When the sprinkler head 13 needs to be replaced, it is only necessary to press the pressing plate 273 at the same time. The pressing plate 273 links the two movable plates 25 to drive the fixed block 26 to separate from each other, and the connection block 21 is extended into the frame 23. The pressing plate 273 is released, and the elastic force released after the spring 271 and the spring 1 24 are compressed brings the driving mechanism 27 back to the original position, and pushes the movable plates 25 to approach each other, and the fixed block 26 enters the blind hole 22, completing the connection between the connecting pipe 12 and the sprinkler head 13. The staff uses the driving mechanism 27 on both sides, so that when the two pressing plates 273 are pressed at the same time, the movable plates 25 on both sides move outward at the same time, so that the fixed block 26 is separated from the blind hole 22 at the same time, realizing the convenient disassembly and installation of the sprinkler head 13, and improving the replacement efficiency. When the pressure rod 272 compresses the spring 271, the telescopic rod 4 expands and contracts with the expansion and contraction of the spring 271. The telescopic rod 4 guides the expansion and contraction of the spring 271 to prevent the spring 271 from being skewed when it is expanded and contracted by the pressure of the pressure rod 272, thereby affecting the normal driving effect of the connecting rod 274 and the push block 275.

[0045] Embodiment 2

[0046] On the basis of the first embodiment, an auxiliary function is added.

[0047] See also Figure 1-4 The fixed block 26 has an inclined surface on one side close to the spray head 13. The inner wall of the movable plate 25 is symmetrically provided with sliders 251, and the inner wall of the frame 23 is symmetrically provided with slide grooves 252, and the sliders 251 are slidably connected to the slide grooves 252. The outer wall of the frame 23 is symmetrically hinged with a protective shell 3, and the protective shell 3 is sleeved on the outside of the driving mechanism 27.

[0048] The inclined surface on the front side of the fixed block 26 allows the staff to install the sprinkler head 13 without pressing the pressing plate 273 in advance: when the sprinkler head 13 needs to be installed, the connecting block 21 only needs to be inserted into the frame 23. When the connecting block 21 contacts the inclined surface on the fixed block 26, the fixed block 26 is automatically pushed in the direction of the spring 1 24, so that the fixed block 26 is automatically separated. When the connecting block 21 moves to the blind hole 22 and the fixed block 26 are on the same axis, the elastic force released after the compression of the spring 1 24 will bounce the fixed block 26 into the blind hole 22, and the automatic connection of the connecting block 21 is completed, which improves the convenience of the device when in use. When the moving plate 25 moves, the slider 251 on the moving plate 25 slides in the slide groove 252, and the slider 251 and the slide groove 252 guide the movement of the moving plate 25, thereby increasing the stability of the moving plate 25 when it moves. The protective shell 3 can be rotated to open to protect the pressure plate 273 and the pressure rod 272 in the driving mechanism 27, so as to prevent the staff from accidentally touching the pressure plate 273 during the spraying operation, thereby contacting the fixation of the spray head 13 and affecting the normal use of the spray head 13.

[0049] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
