Description

[Detailed description of the invention] This invention provides vertical grooves and dogleg grooves in the stationary lid and rotating lid,
The present invention relates to a paint container for a spray gun in which the paint cup can be easily attached and removed by making it possible to pull up a locking pin provided on the upper end of the paint cup using the groove.

Conventionally, in the case of a suction type paint container for a spray gun, a lid is provided on the suction pipe that is placed below the spray gun.
Fix the paint cup by screwing it directly onto the lid, or extend a yoke from the suction pipe, lock the end of the yoke with a locking pin installed on the side of the paint cup, and then pull up the yoke. As a result, it is formed so as to be in close contact with the lid body.

The above-mentioned screw type requires time to attach the lid and has poor workability, and those using a yoke are usually installed with a clearance between the yoke and the suction pipe, so the yoke is not necessary. As a result of being stable, there are inconveniences such as requiring time and effort to fit it.

The object of the present invention is to provide a paint container for a spray gun (hereinafter referred to as a container) that is equipped with a stationary lid and a rotating lid that is attached to the stationary lid and can solve the above-mentioned problems. Examples will be described based on the drawings.

In the figure, the container 1 of the present invention fixes a paint cup 5 using a stationary lid 3 fixed to a suction pipe 2 and a rotating lid 4 attached to the stationary lid 3. The upper pipe 2 is connected to a paint nozzle 7 provided on the spray gun 6 and is fixed to a nipple 10 screwed into the bottom of the spray gun 6, so that the upper pipe 2 hangs down from the spray gun 6 at a lower level.

In this embodiment, the nipple 10 has a stepped flange portion 11 into which a cylinder 12 is fitted.

The stationary lid 3 has a cap shape made of sheet metal, and a boss portion 13 that fits into the cylinder 12 is provided with first and second step portions 15 and 16 in the shape of concentric circles having a center position in front of the boss portion 13. The stationary lid 3 has a cylindrical inner circumferential wall 17 on which the paint cup 5 is fitted, and the static lid 3 has a seal inserted from the back side into the second stepped portion 16. By sandwiching the ring 18 and the plate 19 and tightening the nut 20, it is attached to the suction pipe 2 while pressing the intervening cylinder 12.

The rotating lid 4 has an inner hole 22 into which the second stepped portion 16 can be fitted, and a bulge 24 formed at a position slightly apart from the inner edge of the inner hole 22 and concentric with the inner hole 22. Further, an outer circumferential wall 26 is provided around the outer circumference of the inner circumferential wall 17 in proximity to the inner circumferential wall 17.

The rotating lid 4 is placed outside the second stepped portion 16.
The inner hole 22 is connected between the wave spring 27 and the ring 29 made of synthetic resin with a small coefficient of friction, and the retaining ring 30 which is screwed on the outside of the first stepped portion 15 and whose outer edge is located near the bulge 24 . By pinching the periphery, it is attached to the stationary lid 3 in a rotatable but non-removable manner.

The retaining ring 30 is provided with a notched portion 31.31 in the outer circumference within a range of about 60°, and a knob 33 forming an inverted shape is attached to the rotating lid 4.

The knob 33 is screwed to the bulge 24 of the rotating lid 4, and its inner end extends inward to the bulge 24, and the extension 35 is located within the cutout 31. The rotating lid 4 can be rotated in forward and reverse directions only within the angular range of the cutout portion 31.

Furthermore, vertical grooves 36 are provided in the inner circumferential wall 19 and the outer circumferential wall 26.
and a dogleg groove 37 are formed.

The vertical groove 36 rises almost perpendicularly from the lower edge of the inner circumferential wall 19 to the vicinity of its upper end, and the doglegged groove 37 consists of a vertical portion 39 rising from the lower edge and an inclined portion 40 at its upper end. The upper end position coincides with the upper end height of the vertical groove 36.

The vertical groove 36 and the vertical portion 39 are such that the knob 33 is connected to the cutout portion 3.
The vertical groove 36 and the doglegged groove 37 are each formed in the middle of the knob 33 and symmetrically with respect to the center of rotation of the rotating lid 4.

The paint cup 5 has a pair of locking pins 42 symmetrically protruding from its upper end, and the vertical groove 36 and the doglegged groove 37 have widths suitable for loosely inserting the locking pins 42 therein.

Note that 50 in the figure is an extension of the suction pipe 2 extending forward of the lower end of the paint cup 5, and can be connected using a joint 51.

However, in the container 1 of the present invention, after rotating the rotary lid 4 using the knob 33 and aligning the vertical groove 36 and the vertical part 39, the locking pin of the paint cup 5 is pushed up to the upper end of the vertical part 39. Insert 42.

Thereafter, by rotating the knob 33, the locking pin 42 is pulled up in the vertical groove 36 along the inclined portion 40, as shown by the dashed line in FIG. The paint cup 5 is fixed by applying strong pressure to the back surface.

When removing the paint cup 5, the paint cup 5 can be removed from the aligned vertical groove 36 and three vertical parts by rotating the knob 33 in the opposite direction.

Further, since the vertical groove 36 is provided in the inner circumferential wall 19 of the stationary lid 3, the locking pin 42 does not rotate when the locking pin 42 is pulled up, thus allowing stable attachment.

Furthermore, since a wave spring 27 is interposed between the stationary lid 3 and the rotating lid 4 and a ring 29 is attached, there is no play between the two, and the rotating lid 4 can rotate smoothly. do.

The paint container of the present invention has vertical grooves and dogleg grooves on the inner and outer walls of a stationary lid fixed to a suction pipe and a rotating lid attached to the stationary lid. Since the locking pin inserted into each groove pulls up the paint cup, the paint cup can be fixed by simply rotating the rotary lid within a small angle range, and can be fixed easily with the stationary lid. A rotating lid is a paint container for a spray gun that can be stably and firmly attached to the bottom of the suction pipe, making it easy to insert a locking pin, making it easy to handle, and allowing the paint cup to be attached and removed easily and quickly. can be provided.

Note that when a vertical groove is provided in a stationary cover, the locking pin is prevented from rotating when the locking pin is pulled up, but the rotating cover allows the locking pin to be tightened with a relatively small rotation range. To make this possible, the rotating lid may be provided with a dogleg groove, and the stationary lid can be attached not only through the cylinder, but also by extending the stationary lid upward and directly contacting the bottom surface of the spray gun with a rising wall. It may be provided as a suction pipe, or it may be modified in various ways, such as by providing a larger number of knobs.
