[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the scope of protection of the present utility model.

[0024] Please see Figures 1 to 5 This utility model provides a testing device for testing spray guns 6, including a support base 1, a pressing mechanism 2, a fixed bracket 3, an air source assembly 4, and a water source assembly 5. The pressing mechanism 2 and the fixed bracket 3 are both mounted on the support base 1. The fixed bracket 3 is used to mount several spray guns 6. The air source assembly 4 is used to connect to the air inlet channel 61 on the spray gun 6, and the water source assembly 5 is used to connect to the water inlet channel 62 on the spray gun 6. The pressing mechanism 2 includes several pressing heads 21, each corresponding to a button on one of the spray guns 6. The buttons include an air source button 64 and a water source button 63. The air source button 64 controls the air inlet channel 61 to connect with the outlet channel 65 on the spray gun 6, and the water source assembly 5 controls the water inlet channel 62 to connect with the outlet channel 65 on the spray gun 6. The pressing mechanism 2 drives the pressing heads 21 to press the water source button 63 and the air source button 64.

[0025] Since this application allows for the mounting of multiple spray guns 6 via the fixed bracket 3, multiple spray guns 6 can be tested simultaneously. Furthermore, because it includes an air source assembly 4 and a water source assembly 5, the air blowing function, water spraying function, or air-water mixed spraying function of the spray guns 6 can be tested on this testing equipment.

[0026] According to some embodiments of this utility model, the pressing mechanism 2 further includes a driving member 22, a connecting plate 23, a sliding plate 24, and an adjusting plate 25. The connecting plate 23 is disposed on the support base 1, the driving member 22 is disposed on the connecting plate 23, the sliding plate 24 is slidably connected to the connecting plate 23 and connected to the power output end of the driving member 22, and the adjusting plate 25 is disposed on the side of the sliding plate 24 away from the driving member 22. The pressing head 21 is detachably disposed on the adjusting plate 25. The driving member 22 is used to drive the sliding plate 24 to slide on the connecting plate 23 to drive the pressing head 21 to press the water source button 63 and the air source button 64. Preferably, the driving member 22 can be a cylinder or an electric cylinder. The driving rod on the cylinder or electric cylinder is directly connected to the sliding plate 24. Taking a cylinder as an example, when the driving rod of the cylinder extends, it pushes the sliding plate 24 to slide toward the button on the spray gun 6, and the pressing head 21 presses the button. When the cylinder's drive rod retracts, it pulls the sliding plate 24 away from the button on the spray gun 6, and the pressing head 21 releases the button. This cycle repeats, and the durability of the button on the spray gun 6 is tested by the repeated extension and retraction of the cylinder.

[0027] According to some embodiments of this utility model, both the sliding plate 24 and the connecting plate 23 are inclined. Since the buttons on the spray gun 6 are located on the inclined surface of the spray gun 6, the sliding plate 24 and the connecting plate 23 need to be adapted to be inclined in order to better drive the pressing head 21 to correspond with the buttons.

[0028] According to some embodiments of this utility model, the adjusting plate 25 has a mutually communicating insertion hole 251 and a threaded hole 252. The central axis of the insertion hole 251 is parallel to the inclination direction of the sliding plate 24, and the central axis of the threaded hole 252 is perpendicular to the inclination direction of the sliding plate 24. The pressing head 21 includes a pressing part 211 and a rod part 212 connected to each other. The pressing part 211 is used to abut against the water source button 63 and the air source button 64. The insertion hole 251 allows the rod part 212 to be inserted. The threaded hole 252 is used to be threadedly connected to a screw 253 to fix the rod part 212 in the insertion hole 251. In this embodiment, the pressing head 21 is made of plastic, which can effectively avoid wear on the buttons during pressing. The distance between the pressing head 21 and the buttons can be easily adjusted by simply tightening and loosening a screw. Specifically, loosen the screw, the rod part 212 slides into the insertion hole 251 to a suitable position, and then tighten the screw.

[0029] According to some embodiments of this utility model, the sliding plate 24 is provided with a slider 241, and the connecting plate 23 is provided with a guide rail 231, with the slider 241 slidably connected to the guide rail 231. In this embodiment, the slider 241 is used in conjunction with the guide rail. By reducing friction, the sliding plate 24 can move more smoothly, thereby extending the service life of the equipment. The guide rail can provide stable support and effectively prevent unnecessary shaking or displacement of the sliding plate 24 during movement, ensuring stable operation of the equipment.

[0030] According to some embodiments of this utility model, two sliders 241 and two guide rails 231 are provided. A connecting rod 242 is provided on the sliding plate 24. The connecting rod 242 is located in the middle of the two sliders 241. The connecting rod 242 is rotatably connected to the power output end of the driving member 22. The conveying direction of the power output end of the driving member 22 is perpendicular to the central axis of the connecting rod 242. Due to the cooperation between the sliders 241 and the guide rails, the sliding plate 24 will not deviate during movement. However, there may be slight installation errors between the various components. For example, there is usually a certain installation error between the driving member 22 and the sliding plate 24. The rotatable connection between the power output end of the driving member 22 and the connecting rod 242 can effectively compensate for the above errors, ensuring smooth and reliable movement.

[0031] According to some embodiments of this utility model, the fixed bracket 3 is threadedly connected to the spray gun 6. Typically, the spray gun 6 has threads, so it can be quickly installed on the fixed bracket 3 for testing by screwing it in; after testing, the spray gun 6 can be quickly removed from the fixed bracket 3 by screwing it in.

[0032] According to some embodiments of this utility model, the air source assembly 4 includes an air pump 41 and an air source valve group 42 that are interconnected. The air source valve group 42 is provided with a plurality of air switch valves 421 spaced apart, and each of the air switch valves 421 is connected to an air inlet channel 61 on a plurality of spray guns 6. In this embodiment, because multiple corresponding air switch valves 421 are provided, each spray gun 6 is an independent air source. When one of the spray guns 6 malfunctions, only the corresponding air switch valve 421 needs to be closed to suspend the testing of that spray gun 6 without affecting the normal testing of other spray guns 6.

[0033] According to some embodiments of this utility model, the support base 1 is provided with a water guide trough 7 and a water storage tank 8. The water guide trough 7 allows the outflow channel 65 to be inserted, and the water guide trough 7 is in communication with the water storage tank 8. In this embodiment, the water guide trough 7 collects the water flowing out of the outflow channel 65 and then returns it to the water storage tank 8. The water pump 51 then draws water from the water storage tank 8 to test the spray gun 6. This cycle is repeated to achieve water recycling and avoid water waste.

[0034] According to some embodiments of this utility model, the water source component 5 includes a water pump 51 and a water source valve group 52 that are interconnected. The inlet of the water pump 51 is connected to a water storage tank 8. The water source valve group 52 is provided with a plurality of water switch valves 521 at intervals, and the plurality of water switch valves 521 are connected one-to-one with the water inlet channels 62 on the plurality of spray guns 6. In this embodiment, since multiple corresponding water switch valves 521 are provided, each spray gun 6 is an independent water source. When one of the spray guns 6 malfunctions, only the corresponding water switch valve 521 needs to be closed to suspend the test of that spray gun 6 without affecting the normal test of other spray guns 6.
