[0042] Preferably, the pushing block 104e is wedge-shaped, one side of which is inclined, and the clamping block 104f is arranged at the lower end of the inclined side of the pushing block 104e, and the pushing block 104e and the pushing column 201c are arranged in a matching manner, when the pushing column 201c rotates with the rotating column 201a, the pushing column 201c can push the inclined surface of the pushing block 104e and guide the inclined surface of the pushing block 104e downward, so that the adjusting ring 104a gradually rises under the restriction of the positioning teeth 105, until the clamping between the bottom positioning opening 104g of the adjusting ring 104a and the positioning teeth 105 is disengaged, and at the same time, the pushing column 201c moves to the end of the clamping block 104f and separates from the pushing block 104e, so that the adjusting ring 104a stops moving upward, and through the abutment between the pushing column 201c and the clamping block 104f, the adjusting ring 104a is driven to rotate with the further rotation of the rotating column 201a, and the purpose of adjusting the different corresponding openings 104b of the adjusting ring 104a to cooperate with the paint pipe 102 according to the spraying needs can be achieved, which ensures the stability of the use of the adjusting ring 104a and makes the adjustment of the spraying type more convenient.

[0044] Embodiment 2

[0045] Referring to FIGS. 1-6, the second embodiment of the present application is based on the previous embodiment, and the difference between the two embodiments is that:

[0046] The control member 201 further comprises a limiting disc 201d fixedly arranged at the top of the rotating column 201a, and the outer side of the middle part of the limiting disc 201d is coaxially sleeved with a pushing tooth ring 201e and a ratchet ring 201f from bottom to top.

[0047] The adjusting component 200 further comprises a transmission member 202 arranged outside the control member 201, the outer part of the transmission member 202 is provided with a lifting member 203, and the inner side of the lifting member 203 is provided with a transition member 204.

[0048] Specifically, the transmission member 202 comprises a driving tooth 202a located between the limiting discs 201d, which can be supported and limited by the limiting discs 201d to ensure stable placement and transmission of the driving tooth 202a. The inner side of the lower part of the driving tooth 202a is provided with a base 202b, the inside of the base 202b is provided with a supporting spring 202c, the outer side of the supporting spring 202c is provided with an abutting block 202d, the rear end of the abutting block 202d is located inside the base 202b, and the supporting spring 202c is located between the abutting block 202d and the base 202b, which can support the abutting block 202d to extend and contract in the base 202b. Meanwhile, the inner side of the upper part of the driving tooth 202a is also provided with a push rod 202e.

[0049] The lifting member 203 comprises a driven tooth 203a rotatably sleeved on the paint pipe 102, and the inner side of the lower part of the driven tooth 203a is integrally provided with a guide column 203b.

[0050] The transition member 204 comprises a transition pipe 204a arranged at the lower end inside the paint pipe 102, the bottom of the transition pipe 204a is provided with a sealing washer 204b, and the outer wall of the transition pipe 204a is provided with a guide groove 204c and a positioning rail 204d.

[0051] Further, the inner wall of the paint pipe 102 is also provided with a positioning groove 102a, and the positioning rail 204d on the transition pipe 204a is movably embedded in the positioning groove 102a. Therefore, through the sliding fit between the positioning groove 102a and the positioning rail 204d, the movement track of the transition pipe 204a is limited, so that the transition pipe 204a can only move axially under the external transmission.

[0052] The driven tooth 203a and the driving tooth 202a are in meshing fit, that is, through the rotation of the rotating column 201a, the driven tooth 203a can be rotated synchronously under the transmission of the driving tooth 202a. Meanwhile, the guide column 203b on the driven tooth 203a is movably embedded in the inside of the guide groove 204c, and the guide groove 204c is spirally and obliquely arranged along the outer wall of the transition pipe 204a. Therefore, under the pushing of the guide column 203b to the guide groove 204c and the oblique guidance of the guide groove 204c itself, the transition pipe 204a in the limiting state of the positioning groove 102a can be linked with the driven tooth 203a, that is, the transition pipe 204a can move axially along with the rotation of the driven tooth 203a to adjust the distance between the transition pipe 204a and the adjusting ring 104a before the rotation of the adjusting ring 104a, so as to avoid the resistance caused by the surface contact between the transition pipe 204a and the adjusting ring 104a to affect the smooth adjustment of the adjusting ring 104a.

[0053] Further, the periphery of the pushing gear ring 201e is uniformly distributed with several pushing gears, and the abutting block 202d can be matched with each pushing gear respectively, so that through the matching arrangement between the abutting block 202d and the pushing gear, when the rotating column 201a rotates, the abutting block 202d can be driven to rotate by the pushing force of the pushing gear, so as to realize the transmission of the driven gear 203a, and when the guide column 203b on the driven gear 203a slides to the other end of the guide groove 204c and causes the driven gear 203a to be locked, under the expansion and contraction matching of the abutting block 202d and the supporting spring 202c, the abutting block 202d can be retracted into the base 202b, so as to achieve the purpose that the rotating column 201a can still continue to rotate and the driving gear 202a stops linkage, and ensure the smooth adjustment of the adjusting ring 104a.

[0054] The ratchet teeth on the ratchet ring 201f are inclinedly distributed in the counterclockwise direction, and the push rod 202e on the driving gear 202a is clamped between the ratchet ring 201f, when the rotating column 201a rotates counterclockwise to adjust the adjusting ring 104a, because of the direction of the ratchet teeth on the ratchet ring 201f, the push rod 202e can be continuously pushed on the ratchet ring 201f by the rotation of the ratchet ring 201f, and the relative movement between the push rod 202e and the ratchet ring 201f, and when the rotating column 201a rotates counterclockwise to control the adjusting ring 104a to reset, at this time, the ratchet teeth on the ratchet ring 201f can act on the push rod 202e on the convex side, so that the driving gear 202a is synchronously rotated under the pushing of the ratchet ring 201f on the push rod 202e, so as to realize the rotation control of the driving gear 202a, so as to achieve the purpose of synchronously controlling the transition pipe 204a to move downward when the adjusting ring 104a is reset and locked, so that the bottom sealing ring 204b of the transition pipe 204a abuts against the adjusting ring 104a, so as to ensure that the type of paint spraying can be conveniently controlled, and the sealing of the spray head adjusting mechanism can be considered.

[0055] In use, the rotating rotating column 201a is rotated, and the adjusting ring 104a is moved upward under the action of the push column 201c and the push block 104e, so as to be separated from the connection of the positioning teeth 105, so as to adjust the position of the corresponding port 104b on the adjusting ring 104a in sequence. At the same time, the main gear 202a is driven by the rotating column 201a through the cooperation between the abutting block 202d and the push gear ring 201e, so as to drive the driven gear 203a to rotate, and the transition pipe 204a and the sealing washer 204b are moved upward under the cooperation of the guide column 203b and the guide groove 204c. In particular, the projection length of the guide groove 204c in the axial direction is greater than the length of the push block 104e in the axial direction, so that the upward movement distance of the transition pipe 204a is greater than that of the adjusting ring 104a, so as to realize the separation between the adjusting ring 104a and the transition pipe 204a. Finally, the rotating column 201a is continuously rotated, the push column 201c moves to the clamping block 104f, and the position adjustment of the corresponding port 104b on the adjusting ring 104a is performed. At this time, the guide column 203b moves to the end of the guide groove 204c, so that the driven gear 203a is in a locked state. Through the extension and retraction of the abutting block 202d, the push gear ring 201e can extrude the abutting block 202d to meet the continuous rotation requirement of the transmission column, and through the cooperation of the push gear block outside the push gear ring 201e and the abutting block 202d, the rotation indication of the adjusting ring 104a is realized. When the rotating column 201a is blocked, the corresponding port 104b is located below the transition pipe 204a. After the outer wall of the adjusting ring 104a is adjusted, the rotating column 201a is reversed. At this time, the push column 201c is gradually reset along the push block 104e. The adjusting ring 104a is moved downward and is positioned again through the cooperation of the positioning teeth 105. At the same time, through the cooperation of the ratchet ring 201f and the push rod 202e, the main gear 202a is rotated again synchronously with the rotating column 201a, so as to drive the transition pipe 204a to reset through the driven gear 203a, so that the sealing washer 204b is in contact with the adjusting ring 104a to realize sealing again. At this time, the spray port adjustment is completed, and the spraying operation can be performed. Through the cooperation between the control member 201, the adjusting member 104, the transmission member 202 and the lifting member 203, the position adjustment and positioning of the corresponding port 104b can be realized by rotating the rotating column 201a, so that the operation of the spray port adjustment is more convenient and efficient. Without replacing the spray gun, the user's use requirement in different working conditions can be met. In the adjusting process, the paint pipe 102 can be closed. After the adjustment is completed, the connection between the transition pipe 204a and the adjusting ring 104a can be sealed, so as to avoid the overflow of paint as much as possible, and the stability and sealing performance of the spray port adjusting mechanism in the whole adjusting and using process are ensured.

[0059] The closure 205 comprises an inner pipe 205a fixed to the inner wall of the paint pipe 102, the bottom of the inner pipe 205a is provided with a through hole for paint to pass through, and the inside of the through hole is hingedly provided with a sealing plate 205b on both sides, the bottom surface of the sealing plate 205b is provided with a clamping rail 205c, the inside of the clamping rail 205c is provided with a jacking rod 205d, the other end of the jacking rod 205d is fixed to the inner wall of the transition pipe 204a, and the two sides of the sealing plate 205b are further provided with a curtain 205e.

[0060] The top end of the jacking rod 205d slides inside the clamping rail 205c, and its movement is guided by the clamping rail 205c, and the top of the jacking rod 205d is always in abutment with the sealing plate 205b, when the transition pipe 204a moves up, the sealing plate 205b can be rotated and reset under the jacking of the jacking rod 205d, and the bottom through hole of the inner pipe 205a is closed, so as to avoid paint leakage when the adjusting ring 104a is adjusted, at the same time, the curtain 205e on both sides of the sealing plate 205b is arranged, when the sealing plate 205b is lowered, it can form a complete channel with the sealing plate 205b to pass the paint, so as to avoid the influence of scattered paint on the spraying effect, and when the sealing plate 205b is retracted, the sealing plate 205b can bring the paint on the inside of the sealing plate 205b back to the transition pipe 204a under the cooperation of the curtain 205e, so as to avoid a large amount of paint remaining on the adjusting ring 104a to affect the normal adjustment of the adjusting ring 104a.
