DETAILED DESCRIPTION

[0021] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0022] Reference Figure 1-5 A handrail box of an engineering machinery comprises a storage box 2, a storage slot 16 is provided in the storage box 2, an armrest board 1 is fixedly connected to the upper end of the storage box 2, a cup board 7 is fixedly connected to the side wall of the storage box 2, two cup slots 15 are provided in the cup board 7, the cup slots 15 are symmetrically distributed at both ends of the cup board 7, four small springs 18 are fixedly connected to the inner wall of the cup slot 15, one end of the small spring 18 away from the cup slot 15 is fixedly connected to a U-shaped plate 12, eight slide slots 22 are provided in the cup slot 15, and the slide slots 22 are distributed at the bottom ends of adjacent U-shaped plates 12. It should be noted that the width of the slide slot 22 is slightly larger than the width of the U-shaped plate 12, so that the U-shaped plate 12 can slide freely in the slide slot 22 to prevent the cup from getting stuck.

[0023] The U-shaped plate 12 slides in the slide groove 22, and a smoke extinguishing groove 11 is provided on the water cup plate 7. An ashtray 17 is slidably connected to the smoke extinguishing groove 11. A guiding mechanism for guiding the ashtray 17 is installed on the smoke extinguishing groove 11. The guiding mechanism includes two sliders 20. Two slideways 13 are provided on the inner wall of the smoke extinguishing groove 11. Each slider 20 is fixedly mounted on the side wall of the ashtray 17, and the sliders 20 slide in adjacent slideways 13.

[0024] A handle 19 is fixedly connected to the upper end of the ashtray 17, and a water spraying mechanism for extinguishing smoke is installed on the smoke extinguishing groove 11. The water spraying mechanism includes a connecting rod 10, a spring 9, a piston 8, a water bucket 5, a water inlet pipe 4, a water spraying pipe 6, and a water tank 3. One end of the spring 9 is fixedly connected to the bottom end of the water cup plate 7, and the other end of the spring 9 is fixedly connected to the upper end of the piston 8. It should be noted that the function of the spring 9 is that when the connecting rod 10 drives the piston 8 to move downward, the elastic force generated by the spring 9 can reset the piston 8 and the spring 9 for the next operation. The connecting rod 10 is fixedly installed on the upper end of the piston 8, and the connecting rod 10 slides in the water cup plate 7, and the piston 8 slides tightly in the water bucket 5. One end of the water spraying pipe 6 is connected to the smoke extinguishing groove 11, and the other end of the water spraying pipe 6 is connected to the water tank 3. The water bucket 5 is fixedly installed on the side wall of the water tank 3, and the water tank 3 is fixedly installed at the bottom of the storage box 2.

[0025] The upper end of the water spray pipe 6 is fixedly connected with a telescopic tube 14. It should be noted that when the ashtray 17 is picked up, the telescopic tube 14 is pressed inward to prevent the telescopic tube 14 from hindering the movement of the ashtray 17, and when the ashtray 17 is put back into the smoke extinguishing groove 11, the telescopic tube 14 is pulled back into the ashtray 17 to prevent water from spilling into the smoke extinguishing groove 11 when spraying water.

[0026] Four U-shaped plates 12 are evenly distributed around the water cup groove 15 , four small springs 18 are evenly distributed around the water cup groove 15 , and a telescopic pipe groove 21 is opened on the side wall of the ashtray 17 .

[0027] A one-way water inlet valve is installed in the water inlet pipe 4, and a one-way water spray valve is installed in the water spray pipe 6. It should be noted that the function of the one-way water inlet valve is that when the piston 8 moves upward, the one-way water inlet valve opens, so that water can only flow from the water tank 3 through the water inlet pipe 4 to the water bucket 5. The function of the one-way water spray valve is that when the piston 8 moves downward, the one-way water spray valve opens, so that water can only be sprayed out from the water bucket 5 along the water spray pipe 6.

[0028] When sundries need to be placed, the armrest 1 is opened and the sundries are placed in the storage groove 16. When a cup needs to be placed, the cup is pressed down along the cup groove 15, at which time, the U-shaped plate 12 presses the small spring 18 inward, and the force generated by the small spring 18 outward fixes the cup in the cup groove 15.

[0029] If you want to extinguish a cigarette butt, place the cigarette butt in the ashtray 17, press the connecting rod 10 downward, and the connecting rod 10 drives the piston 8 to move downward. At this time, under the action of the water spray check valve, the water in the bucket 5 can only be sprayed out from the water spray pipe 6 through the telescopic tube 14, and the cigarette butt is extinguished. At the same time, the elastic force of the spring 9 resets the piston 8 and the connecting rod 10. At this time, under the action of the water inlet check valve, the water in the water tank 3 can only flow into the bucket 5 through the water inlet pipe 4 for the next water spray operation. It should be noted that it is not necessary to spray water every time a cigarette butt is thrown. When the water in the ashtray 17 is not enough to extinguish the cigarette butt, the water spray operation is performed, which can save water and avoid waste of water resources.

[0030] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
