DETAILED DESCRIPTION

[0020] 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.

[0021] See also Figure 1-5 The utility model provides a technical solution: a school sports field marking device, including a base 1, a paint bucket 7 is detachably connected to the top of the base 1, a cover 5 is threadedly connected to the upper side of the paint bucket 7, a delivery pipe 14 is connected to the upper side of the base 1, the delivery pipe 14 is connected to the paint bucket 7, a horizontal plate 11 is fixedly arranged on the lower side of the base 1, a pressure rod 9 is hinged on the front side of the horizontal plate 11, a hollow mounting rod 19 is fixedly connected to the lower end of the pressure rod 9, a roller head 10 is threadedly connected to the outer side of the mounting rod 19, the delivery pipe 14 is penetrated into the inner side of the pressure rod 9 and is connected to the inside of the roller head 10; a tension spring 15 is arranged on the upper side of the pressure rod 9, and the upper and lower ends of the tension spring 15 are rotatably connected with a pin rod 16, the upper pin rod 16 is fixedly connected to the horizontal plate 11, and the lower pin rod 16 is fixedly connected to the pressure rod 9, the left and right sides of the base 1 are fixedly connected to support plates, and the front and rear sides of the support plates are connected to wheels 4.

[0022] First, open the cover 5, add the paint for marking the sports field into the paint bucket 7, and tighten the cover 5. According to the need of marking the sports field, move the position of the device. Since the delivery pipe 14 is connected with the paint bucket 7, the school sports field is marked by the roller head 10 on the lower side of the mounting rod 19. The pressure rod 9 and the tension spring 15 are used in conjunction to prevent the roller head 10 from being uneven on the ground during movement, which may cause line breakage during marking, and also prevent the roller head 10 from being damaged by the ground during marking.

[0023] A plurality of fixed ribs 6 are fixedly connected to the outer circumference of the upper side of the paint bucket 7 , and a through hole is opened on the lower side of the fixed rib 6 . A locking screw is passed through the inner side of the through hole, and the lower side of the locking screw is threadedly connected to the base 1 .

[0024] The position of the fixed rib plate 6 on the base 1 is fixed by a locking screw, so as to facilitate fixing the position of the paint bucket 7 on the base 1.

[0025] A hollow joint is fixedly connected to the lower side of the paint bucket 7, and two positioning pins 17 are fixedly connected to the lower side of the joint. A sealing gasket 18 is inserted into the positioning pins 17. A positioning hole 21 is opened at the upper end of the middle part of the base 1, and the positioning pins 17 are plugged into the positioning hole 21.

[0026] The delivery pipe 14 is fixedly connected to the joint and is plugged into the positioning pin 17 and the positioning hole 21 so that the lower part of the joint of the paint bucket 7 is located directly above the upper end of the delivery pipe 14 .

[0027] An adjusting plate 8 is slidably connected to the middle of the base 1. The base 1 has an opening hole 22. The upper end of the delivery pipe 14 is fixedly connected to the opening hole 22. The opening hole 22 is coaxial with the joint. The adjusting plate 8 has a connecting hole 12. The upper end of the delivery pipe 14 is flush with the lower end of the adjusting plate 8.

[0028] When it is necessary to close the connection between the delivery pipe 14 and the paint bucket 7, the position of the adjusting plate 8 is moved forward, so that the connecting hole 12 is moved away from the position of the opening hole 22, thereby blocking the connection between the lower end joint of the paint bucket 7 and the opening hole 22, and making the connecting hole 12 and the opening hole 22 deviate from the coaxial position, so that the lower end of the joint is blocked by the rear side position of the connecting hole 12 of the adjusting plate 8.

[0029] The rear side of the adjusting plate 8 is fixedly connected with a top plate 13 , the top plate 13 is plugged with a limit plate 20 , and the limit plate 20 is fixedly connected to the base 1 .

[0030] The limiting plate 20 has the function of limiting the forward and backward movement of the adjusting plate 8. When the adjusting plate 8 is moved forward, the connection between the lower joint of the paint bucket 7 and the conveying pipe 14 is closed, and the adjusting plate 8 is pulled back. When the adjusting plate 8 contacts the limiting plate 20, the joint, the opening hole 22 and the conveying pipe 14 are interconnected.

[0031] A handrail 2 is fixedly connected to the upper rear portion of the support plate, and a handrail 3 is fixedly connected to the upper end of the handrail 2.

[0032] The utility model moves the handrail 3. Due to the fixed connection between the handrail 3 and the handrail 2 and the connection between the support plate and the wheel 4, it is convenient to move the position of the device and to mark the sports field through the roller head 10.

[0033] When the utility model is used, the cover 5 is first opened, the paint for marking the sports field is added into the paint bucket 7, and the cover 5 is hung. According to the need of marking the sports field, the position of the device is moved, and the school sports field is marked by the roller head 10 on the lower side of the mounting rod 19.

[0034] Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments, or make equivalent substitutions for some of the technical features therein.
