Description

Technical Field

[0001] The utility model relates to a spray gun, in particular to a dual-purpose spray gun device. Background Art

[0002] The spray gun is a commonly used tool for spraying paint, pigment, etc. When in use, the spray gun is held in the hand to spray. However, for this handheld spray gun, the volume of the material pot is generally small, otherwise it will increase the hand-held weight of the user, and the arm will be more easily fatigued. Therefore, this handheld spray gun is suitable for spraying small areas. When a large area needs to be sprayed, it is necessary to remove the material pot for liquid addition many times, and the operation is frequent. In order to increase the volume of the material pot, some spray guns are set to drag type, and rollers are installed on the base of the spray gun, and then the gun head assembly of the spray gun is connected to the gun body through a hose. However, this large-volume drag-type spray gun is not convenient to carry, and when only a small area needs to be sprayed, it causes a waste of resources. Summary of the invention

[0021] The present invention will be described in further detail below in conjunction with the accompanying drawings.

[0022] As shown in the figure, a dual-purpose spray gun device includes a base 1, a handheld spray gun 2 and a gun head assembly 3. A roller 9 is arranged at the lower end of the base 1, and an inner cavity with an upper end opening is arranged on the base 1 (not marked in the figure). A detachable large material pot 4 is arranged at the front end of the inner cavity. In order to prevent the large material pot 4 from slipping out of the inner cavity, an elastic positioning piece 12 can be arranged at the inner bottom of the front end of the inner cavity, and a positioning protrusion 44 is arranged at the bottom of the large material pot 4. When the large material pot 4 is loaded into the front end of the inner cavity, the elastic positioning piece 12 is abutted against the positioning protrusion 44. When the large material pot 4 needs to be taken out of the inner cavity, the large material pot 4 can be pulled hard to make the positioning protrusion 44 at the bottom of the large material pot 4 pass over the elastic positioning piece 12; when the handheld spray gun is 2 is placed in the inner cavity, the small material pot 21 and the nozzle assembly 22 on the handheld spray gun 2 are removed, the pot cover 23 on the handheld spray gun 2 is matched with the pot mouth 41 of the large material pot 4, the upper end of the large material pot 4 is provided with a feeding port 42, and a feeding cover 43 is screwed on the feeding port 42. When the feeding cover 43 is tightened on the feeding port 42, the feeding cover 43 presses the pot cover 23 on the handheld spray gun 2, and the gun head assembly 3 is connected to the front end of the handheld spray gun 2 through a hose 5. A power adapter is fixedly provided in the rear end of the base 1, one end of the power adapter is plugged and matched with the power end of the handheld spray gun 2, and the other end is connected to an external power supply. The base 1 is provided with a toggle mechanism 7 for toggling the trigger 24 on the handheld spray gun 2;

[0023] The toggle mechanism 7 includes a knob 71, a lever 72 and a spring 73. A mounting seat 13 is fixedly provided on the base 1, a locking sleeve 14 is fixedly provided on the mounting seat 13, and an L-shaped first locking groove 15 is provided on the locking sleeve 14. The knob 71 is fixed to the outer end of the lever 72, and the inner end of the lever 72 horizontally passes through the locking sleeve 14 and the mounting seat 13. An eccentric block 74 is fixedly provided at the inner end of the lever 72, and a locking pin 75 is radially fixed on the lever 72. The locking pin 75 passes through the first locking groove 15, and the spring 73 is sleeved on the lever 72 and the two ends thereof are against the locking pin 75 and the mounting seat 13. When the lever 72 is pushed inward and the locking pin 75 is screwed into the transverse groove 151 of the first locking groove 15, the eccentric block 74 pushes and locks the trigger 24 on the handheld spray gun 2, so that the handheld spray gun 2 is in a working state.

[0024] In order to ensure that the handheld spray gun 2 is stably placed in the inner cavity of the base 1 during operation, a locking mechanism can be further provided between the base 1 and the rear end of the handheld spray gun 2, and the locking mechanism includes a lock buckle 8, the lower end of the lock buckle 8 is hinged to the base 1, and a second locking groove 25 is provided at the rear end of the gun body of the handheld spray gun 2. The upper end of the lock buckle 8 is buckled into the second locking groove 25, and the feeding cover 43 on the large material pot 4 presses the pot cover 23 on the handheld spray gun 2. The two cooperate to ensure that the handheld spray gun 2 is stably locked.

[0025] In the above embodiments, the handheld spray gun 2 can be an electric spray gun or a high-pressure airless spray gun, preferably a high-pressure airless spray gun. The gun head assembly 3 and the nozzle assembly 22 are both existing conventional components. In addition, the external power supply can be a power cord electrically connected to a power adapter or a battery pack 6. When the external power supply is a battery pack, a slot 16 is provided on the rear end face of the base 1, and the battery pack 6 is inserted into the slot 16, and the other end of the battery pack 6 is plugged and matched with the power adapter. And when the handheld spray gun 2 is taken out of the inner cavity of the base 1, the battery pack 6 can be plugged on the power supply end of the handheld spray gun 2.

[0026] In the above embodiments, the usage method of the dual-purpose spray gun device is as follows: when only a small area needs to be sprayed, the handheld spray gun 2 can be directly held and used for spraying. When it is necessary to install the handheld spray gun 2 into the base 1 and use it as a drag-type spray gun, first remove the small material pot 21 and the nozzle assembly 22 on the handheld spray gun 2, put the handheld spray gun 2 into the inner cavity of the base 1, then match the kettle lid 23 on the handheld spray gun 2 with the kettle mouth 41 of the large material pot 4, tighten the feeding cover 43 on the feeding port 42 and press the kettle lid 23, and then fasten the buckle 8 on the base 1 with the second locking groove 25 at the rear end of the handheld spray gun 2, so that the handheld spray gun 2 is locked on the base 1. At the same time, the power supply end of the handheld spray gun 2 is plugged and matched with one end of the power adapter, and the battery pack 6 is inserted into the slot 16, and the other end of the battery pack 6 is plugged and matched with the power adapter, so that the handheld spray gun 2 is powered on. Then connect the gun head assembly 3 to the front end of the handheld spray gun 2 through a hose 5, then push the lever 72 inward and screw the locking pin 75 into the transverse groove 151 of the first locking groove 15. The lever 72 drives the eccentric block 74 to rotate, and the eccentric block 74 pushes and locks the trigger 24 on the handheld spray gun 2, so that the handheld spray gun 2 is in a working state. Then open the trigger on the gun head assembly 3 and spraying operation can be carried out. When the spraying is finished, rotate the knob 71 to make the locking pin 75 slide out of the transverse groove 151 of the first locking groove 15 and enter the longitudinal groove 152. The spring 73 pushes the lever 72 to move outward and reset. The eccentric block 74 releases the locking of the trigger 24 on the handheld spray gun 2, the trigger 24 resets, and the handheld spray gun 2 stops working.

[0027] The protection scope of the present invention includes but is not limited to the above embodiments. The protection scope is subject to the claims. Any replacement, deformation, and improvement that are easily conceivable by those skilled in the art to this technology fall within the protection scope of the present invention.
