[0028] As Figure 1-6As shown in the figure, a surface coating spray gun system includes a spray gun body 1. A connecting handle 5 is fixedly connected to the lower end of the spray gun body 1. A fixed storage mechanism 7 is fixedly connected to the lower side of the connecting handle 5. A spraying auxiliary mechanism 8 is fixedly connected to the left end of the fixed storage mechanism 7.

[0029] Further, the fixed storage mechanism 7 includes two first fixing frames 711. The relatively close ends of the two first fixing frames 711 are fixedly connected to the connection handle 5. The two first fixing frames 711 are respectively movably connected to the front and rear sides of the worm 710 through the connection holes opened inside their upper ends.

The second rotating shaft 71 is fixedly connected to the spraying auxiliary mechanism 8. By rotating the worm 710, under the action of the two worm wheels 79 provided, the two first rotating shafts 76 can be driven to rotate relatively. By the rotation of the two first rotating shafts 76, under the action of the first bevel gears 74 and the second bevel gears 73 provided, the second rotating shaft 71 can be driven to rotate upward, and then the spraying auxiliary mechanism 8 can be driven to rotate upward around the second rotating shaft 71 to the vertical state.

The front and rear ends of the fixing rod 713 are respectively fixedly connected to the two first fixing frames 711. The relatively far ends of the two first fixing frames 711 are respectively fixedly connected to the relatively close sides of the two second fixing frames 78. During the process of driving the two first rotating shafts 76 to rotate, under the action of the cams 77, the first spring 712 and the fixing rod 713 provided, the two clamping plates 72 can be driven to move away from each other, so that the two clamping plates 72 no longer play a role in clamping and fixing the storage tank 10. At this time, the storage tank 10 can be conveniently removed from the device, the paint can be conveniently added to the storage tank 10 or the storage tank 10 can be conveniently replaced.

[0030] Furthermore, the spraying auxiliary mechanism 8 includes two connecting blocks 88. Both of the two connecting blocks 88 are fixedly connected to the second rotating shaft 71. The left ends of the two connecting blocks 88 are fixedly connected with sleeve rods 84 respectively. Square frames 87 are sleeved on the two sleeve rods 84. Position-limiting pins 810 are arranged on the two square frames 87. Spring two 89 is sleeved on each of the two position-limiting pins 810.

Fixed frames three 86 are fixedly connected to the relatively far ends of the two square frames 87 respectively. Both of the two fixed frames three 86 are movably connected to the front and rear ends of the two third rotating shafts 81 respectively through two connecting holes opened inside them. Drums 83 are fixedly connected to the two third rotating shafts 81. During the spraying process, the drums 83 are made to closely adhere to the spraying surface, and then spraying is carried out from top to bottom. Thus, it can ensure the consistency of the distance between the nozzle 2 and the spraying surface during the spraying process, ensuring the uniformity of spraying. Correspondingly, by pulling up the two position-limiting pins 810 to move them out of the corresponding jacks 85, then the two square frames 87 can be driven to slide on the two sleeve rods 84. Thus, with the cooperation of the scale lines arranged on the two sleeve rods 84, the horizontal distance between the drum 83 and the nozzle 2 can be adjusted, so as to adjust the distance between the nozzle 2 and the spraying surface during the spraying process according to requirements.

[0031] The working principle of the present utility model is as follows:

[0032] When using this device for spraying, first make the left ends of the two drums 83 closely adhere to the spraying surface, then pull the trigger 3. Thus, with the cooperation of the spray gun main body 1, the nozzle 2, the connecting pipe 12 and the connecting head 11 arranged, the paint in the storage tank 10 can be pumped out and sprayed onto the spraying surface. Then, spraying can be carried out by the method of spraying from top to bottom. When the spraying of this device is completed, by rotating the worm 710, under the action of the two worm wheels 79 arranged, the two first rotating shafts 76 can be driven to rotate relatively. Through the rotation of the two first rotating shafts 76, under the action of the first bevel gear 74 and the second bevel gear 73 arranged, the spraying auxiliary mechanism 8 can be driven to rotate upward by 90 degrees around the second rotating shaft 71 until it rotates to the vertical state. At this time, the folding and storage process of the spraying auxiliary mechanism 8 can be realized, reducing the occupied space of this device. And with the cooperation of the connecting handle 5 and the T-shaped support plate 9 arranged, it can be stably placed on the table. During the process of driving the two first rotating shafts 76 to rotate, under the cooperation of the cam 77, the first spring 712 and the fixed rod 713 arranged, the two clamping plates 72 can be driven to move away from each other, so that the two clamping plates 72 no longer play a role in clamping and fixing the storage tank 10. Thus, the storage tank 10 can be conveniently removed from this device and replaced.

[0033] The above are only the preferred embodiments of the present utility model. It should be noted that for those of ordinary skill in the art, without departing from the principle of the present utility model, several improvements and modifications can be made, and these improvements and modifications should also be regarded as the protection scope of the present utility model.
