Abstract
The utility model discloses a flow regulation device and a spray gun, which belongs to the technical field of spraying equipment and accessories of the spraying equipment. In order to overcome the shortcoming that the existing flow regulation device of the spray gun is apt to damage a gun pin and inconvenient to regulate, a corresponding bead screw and a corresponding hemisphere hole are arranged between a regulation knob and a regulation rod of the spray gun, so that the regulation rod and the regulation knob can rotate relatively, and the abutting strength between the regulation rod and the regulation is larger than that between the regulation rod and a swivel nut. On one hand, when the gun pin coincides with a muzzle, namely, flow quantity is zero, the regulation knob and the regulation rod rotate relatively, and the gun pin does not eject forward and damage the muzzle. On the other hand, due to a dial and a dividing ruler on the flow regulation device, each time using the spray gun, users can regulate the regulation rod to enable the regulation rod to coincide with the gun pin and the muzzle, then rotate the regulation knob clockwise to reach a zero position of the dial, finally rotate the regulation knob in an opposite direction to regulate output quantity and record shooting scales of the spray gun. When coatings with different thickness need to be sprayed at different time, the users can quickly regulate needed output quantity without repeat regulation, so that efficiency is increased.
Description
Technical field
The utility model relates to spraying equipment and accessory technical field thereof, specifically is meant a kind of spray gun and flow regulator thereof that sprays liquid.
Background technology
Along with the raising of people's esthetic requirement, the spraying effect of various product requirements is also improving constantly, and impels spraying equipment constantly to improve; In paint spraying, spraying effect embodies by situations such as coating thickness, the uniformity, and the volume control device of spray gun is being controlled the size of coating flow, and the uniformity during to the thickness of spraying and atomizing all has crucial effect.In existing spray-gun flow regulator, typical structure be provided with threaded adjusting rod, with the swivel nut of adjusting rod coupling and the adjusting knob that is loaded on the adjusting rod end, control the aperture of spray gun rifle pin by the screw thread transmission; There are many weak points in this structure: such as in the spray gun use, adjusting knob produces displacement because of shaking or colliding, and discharge-amount changes, and causes spraying uneven; In order to improve this defective, occurred a kind ofly radial wave pearl screw being set, the ball locating slot has been set in the corresponding adjusting knob, be used for adjusting knob is located at the swivel nut outer wall, the discharge-amount that has solved in using changes, but still there is following defective in this structure: the first, when aperture is regulated, there is not the torsion control structure, only, after rifle pin top puts in place, continue the rotation adjusting knob and can make rifle pin needle point top bad with operating personnel's feel control; The second, when spray gun need spray same thickness paint at different times, need contrast debugging repeatedly, efficient is low.
Summary of the invention
Damage rifle pin rifle mouth, the complicated defective of debugging easily at existing flow regulator, the utility model provides a kind of rifle pin that prevents to damage, the spray gun of debugging flow regulator easily again and using this device.
For achieving the above object, the technical solution adopted in the utility model is as follows:
A kind of flow regulator comprises the rifle pin and axially is connected to a threaded adjusting rod of rifle backshank end that this adjusting rod passes the axle center of a swivel nut, is provided with the internal thread that is complementary with the adjusting rod screw thread in the swivel nut; The sheathed adjusting knob of the other end of adjusting rod, one end of described swivel nut also is positioned at adjusting knob, wherein, swivel nut is positioned at one section first ripple pearl screw that is provided with radially of adjusting knob, its ball protrudes the swivel nut lateral wall, and accordingly, the madial wall of described adjusting knob is provided with some axial ball locating slots equably, first this ball locating slot of ripple pearl screw butt, swivel nut and adjusting knob can relatively rotate; Around the outer edge of adjusting knob, corresponding ball locating slot is provided with dial, and is provided with axial rule at the outer wall of described swivel nut, and dial cooperates the displacement that can determine adjusting rod with rule; Lower shaft heart place is provided with cylindrical pit in the described adjusting knob, described adjusting rod is loaded in this pit, be provided with the second ripple pearl screw radially in the sidewall of this adjusting knob pit, its ball one end stretches out the pit sidewall, accordingly, be provided with annular groove around described adjusting rod sidewall, be provided with the hemisphere hole in the groove equably, circumferential slippage also can be done along annular groove in second this hemisphere hole of ripple pearl screw butt; The butt dynamics in the second ripple pearl screw and hemisphere hole is greater than the butt dynamics of the first ripple pearl screw and ball locating slot.
Further, an end of described adjusting rod butt rifle pin is used for adjusting rod and described swivel nut relative fixed for the close-fitting of the band T prefix structure of splicing.
Spray gun comprises rifle body, shower nozzle and above-mentioned flow regulator, and the rifle pin of this flow regulator is installed in the described rifle body by back-moving spring, and its swivel nut is fixed on the rifle body.
The beneficial effects of the utility model are: 1, correspondence is arranged at the first ripple pearl screw on the swivel nut and the ball locating slot on the adjusting knob inwall, can locate adjusting knob, and knob slides and discharge-amount is changed when preventing to use; 2, the corresponding setting of the second ripple pearl screw of the hemisphere hole on the adjusting rod and adjusting knob pit inwall, and the butt dynamics in the second ripple pearl screw and hemisphere hole is greater than the butt dynamics of the first ripple pearl screw and ball locating slot, after the rotation adjusting knob puts rifle pin top in place, when continuing the rotation adjusting knob, the rifle pin can not continue jacking and damage, but adjusting knob and adjusting rod relatively rotate; When 3, using spray gun at every turn, earlier the rifle pin being rotated to discharge-amount is zero, adjusting knob to the dial that continues then to turn clockwise makes zero, last reverse rotation adjusting knob is to regulate required discharge-amount, and record shooting scale value, in the time of in the time of difference, need spraying same thickness, as long as just can regulate required discharge-amount apace according to shooting scale value record, do not need to contrast repeatedly debugging, greatly improved efficient.
