The slide block 40013 drives the U-shaped plate 40016 to slide through the slide rod 40015. The U-shaped plate 40016 can push the limit ring 6006 to drive the polygonal rod 6005 to slide and adjust.

[0069] In this embodiment, a fixing frame 40017 is fixedly connected to the outside of the side frame 100, a guide sleeve 40019 is fixedly connected to the fixing frame 40017, a positioning rod 40018 is slidably connected to the guide sleeve 40019, a top plate 40020 is fixedly connected to the top of the positioning rod 40018, a second spring 40021 is sleeved on the outside of the positioning rod 40018, and the two ends of the second spring 40021 are respectively connected to the top plate 40020 and the fixing frame 40017, and a second spring 40021 is provided on the top of the gear 5002.

[0070] The above technical solution is explained as follows: when it is necessary to store the two side frames 100, it is only necessary to rotate the threaded rod 4005 to allow the first nut block 4006 and the second nut block 4007 to slide synchronously toward the side frame 100; since the pitch of the first thread groove 4008 is greater than the pitch of the second thread groove 4009, under the same number of turns, the distance moved by the second nut block 4007 is greater than the straight-line distance moved by the first nut block 4006. When the first nut block 4006 slides, it will drive the first rack 4001 and the second rack 4002 to slide synchronously, and the second rack 4002 will first drive the arc plate 4001 0 contacts the rotating wheel 40023. With the contact of the arc plate 40010, the positioning rod 40018 is pushed up. When the positioning rod 40018 is completely disengaged from the second positioning port 40024, the second rack 4002 begins to mesh with the gear 5002. When the second nut block 4007 slides, it drives the connecting plate 40011 and the slider 40013 to slide synchronously. The slider 40013 drives the sliding rod 40015 and the U-shaped plate 40016 to slide. The U-shaped plate 40016 pushes the limiting ring 6006 to drive the multi-shaped rod to disengage from the rotating sleeve 5006 and retract into the rotating cylinder 6001.

[0071] When the first rack 4001 and the second rack 4002 are meshed with the gear 5002, the gear 5002 is driven to rotate, and the gear 5002 drives the mounting seat 5003 to rotate through the rotating rod 5001, and the mounting seat 5003 drives the wheel 5004 to rotate until the wheel 5004 is perpendicular to the side frame 100, and then the two side frames 100 are pushed to move toward each other for storage;

[0072] As another embodiment, a film 7002 laying assembly is provided in this embodiment, and the film 7002 laying assembly includes a plurality of groups of adjusting columns 800, one end of the adjusting column 800 is fixedly connected with a threaded column 8003, and the other end of the adjusting column 800 is provided with a threaded recess, wherein the outside of two groups of adjusting columns 800 is fixedly connected with a connecting piece 8001, the outside of the connecting piece 8001 is provided with a through hole 8002, the outside of the adjusting column 800 is provided with a winding sleeve 700, and the winding sleeve 700 is threadedly connected with a positioning bolt 7001 , a film 7002 is wrapped around the outside of the winding sleeve 700; according to the unfolded distance of the side frame 100, multiple groups of adjusting columns 800 can be threadedly spliced ​​with each other, so that the threaded column 8003 on the outside of one adjusting column 800 is connected to the threaded recess on the outside of another adjusting column 800 to achieve splicing and fixation, and then the winding sleeve 700 is set on the outside of the adjusting column 800, and the positioning bolt 7001 is rotated to fix it, and then the connecting piece 8001 is passed through the long bolt on the outside of the rotating column 6002 for threaded fixation, refer to the attached Figure 6 A long bolt is fixedly connected to an outer section of the rotating column 6002. The long bolt is used to pass through the through hole 8002, and the nut on the outer side of the long bolt is used to resist the fixed connecting piece 8001. When the wheel 5004 rotates, it will drive the rotating sleeve 5006 to rotate, the rotating sleeve 5006 drives the polygonal rod 6005 to rotate, the polygonal rod 6005 drives the rotating drum 6001 to rotate, and the rotating drum 6001 drives the rotating column 6002 to rotate through the cooperation of the sprocket 6003 and the chain 6004. The rotating column 6002 drives the adjusting column 800 to rotate, and the adjusting column 800 drives the winding sleeve 700 to rotate. The winding sleeve 700 can release the wound film 7002, so that the film 7002 can be laid on the watered road surface to maintain the road surface.

[0073] In order for those skilled in the art to fully understand the technical solution, the method of using this embodiment is as follows:

[0074] First, rotate the dial plate 20019 to allow the dial plate 20019 to drive the limiting rod 20023 to disengage from the notch 20022;

[0075] Then, the two side frames 100 are pulled to move away from each other. Due to the scissor-type structure of the first connecting rod 200, the second connecting rod 300, the third connecting rod 3001 and the square tube 2001, the two side frames 100 can be opened and moved away from each other. At the same time, the pulley 20010 slides in the first track 2004 and the second track 2008 respectively, and the positioning plate 20013 also drives the positioning head 20014 to be continuously engaged in the first positioning port 20011.

[0076] Multiple groups of adjusting columns 800 are connected by threads, and the winding sleeve 700 is placed on the outside of the adjusting column 800, and fixed by rotating the positioning bolt 7001, and then the connecting piece 8001 is passed through the long bolt on the outside of the rotating column 6002 for threaded fixation;

[0077] After unfolding to a suitable distance, the dial plate 20019 is rotated again to allow the limit rod 20023 to be engaged in the notch 20022. At the same time, the magnet 20021 is adsorbed on the iron plate to fix the position of the dial plate 20019. In this way, the positioning plate 20013 cannot slide, and the position of the slide plate 20012 is fixed, so that the two side frames 100 will not move closer to or away from each other, ensuring the stability of subsequent equipment operation.

[0078] Start the water pump, the water pump draws out the water in the water tank 20026, and delivers it to the square tube 2001 through the delivery pipe 2006. Through the setting of the hose 2002, multiple square tubes 2001 are connected, and finally the water is sprayed out through the nozzle 20025 at the bottom of the square tube 2001 and sprayed on the road surface, so as to realize the watering maintenance of the concrete road surface;

[0079] The motor 5005 is turned on to drive the wheel 5004 to rotate, and the push handle 1001 is manually held to assist the side frame 100 to move forward, thereby achieving continuous watering of the road surface;

[0080] When the wheel 5004 rotates, it drives the rotating sleeve 5006 to rotate, the rotating sleeve 5006 drives the polygonal rod 6005 to rotate, the polygonal rod 6005 drives the rotating drum 6001 to rotate, the rotating drum 6001 drives the rotating column 6002 to rotate through the cooperation of the sprocket 6003 and the chain 6004, the rotating column 6002 drives the adjusting column 800 to rotate, the adjusting column 800 drives the winding sleeve 700 to rotate, the winding sleeve 700 can release the wound film 7002, so that the film 7002 can be laid on the watered road surface to maintain the road surface;

[0081] When the two side frames 100 need to be stored, the dial plate 20019 only needs to be rotated again to disengage the limit rod 20023 from the notch 20022, and then the threaded rod 4005 is rotated to make the first nut block 4006 and the second nut block 4007 slide synchronously toward the side frame 100; since the pitch of the first thread groove 4008 is greater than the pitch of the second thread groove 4009, under the same number of turns, the distance moved by the second nut block 4007 is greater than the linear distance moved by the first nut block 4006;

[0082] When the first nut block 4006 slides, it will drive the first rack 4001 and the second rack 4002 to slide synchronously. The second rack 4002 will first drive the arc plate 40010 to resist the rotating wheel 40023. As the arc plate 40010 resists, the positioning rod 40018 will be pushed up. When the positioning rod 40018 is completely disengaged from the second positioning port 40024, the second rack 4002 starts to mesh with the gear 5002. When the second nut block 4007 slides, it will drive the connecting plate 40011 and the slider 40013 to slide synchronously. The slider 40013 drives the sliding rod 40015 and the U-shaped plate 40016 to slide. The U-shaped plate 40016 pushes the limiting ring 6006 to drive the multi-deformable rod to disengage from the rotating sleeve 5006 and retract into the rotating cylinder 6001.

[0083] When the first rack 4001 and the second rack 4002 are both meshed with the gear 5002, the gear 5002 is driven to rotate, and the gear 5002 drives the mounting seat 5003 to rotate through the rotating rod 5001, and the mounting seat 5003 drives the wheel 5004 to rotate until the wheel 5004 is perpendicular to the side frame 100 (at this time, the polygonal rod 6005 is separated from the rotating sleeve 5006 in advance, so as not to affect the rotation of the wheel 5004), and then the two side frames 100 are pushed to move toward each other for storage. Under the cooperation of the scissor-fork structure of the first connecting rod 200, the second connecting rod 300, the third connecting rod 3001 and the square tube 2001, the two side frames 100 can be quickly stored;

[0084] When opening again, the same principle is followed in reverse, the threaded rod 4005 is rotated to make the first nut block 4006 and the second nut block 4007 slide away from the side frame 100, and through the meshing of the first rack 4001, the second rack 4002 and the gear 5002, the rotating rod 5001 first drives the wheel 5004 to reset parallel to the side frame 100, and at the same time, the second nut block 4007 also drives the connecting plate 40011 to slide, so that the U-shaped plate 40016 plugs the polygonal rod 6005 into the rotating sleeve 5006 again;

[0085] When the first rack 4001 and the second rack 4002 are completely separated from the gear 5002, the arc plate 40010 slowly releases the positioning rod 40018, allowing the positioning rod 40018 to be engaged in the second positioning port 40024, thereby fixing the position of the gear 5002 again, and also fixing the position of the mounting seat 5003.
