The guide rod 5 is positioned below the screw rod 40, and before the sixth magnetic member 33 and the fifth magnetic member 14 are attracted, the second nut portion 32 slides and descends along the guide rod 5.
After the second nut portion 32 descends along the guide rod 5, the sixth magnetic member 33 in the second nut portion 32 can be attracted to the fifth magnetic member 14. When the spray gun 3 slides with the second housing 2, the second nut portion 32 can be separated from the first and second limit portions 34 and 35 on the spray gun body 30. As the spray gun 3 and the second housing 2 are further extended outward with respect to the housing portion 10, the second stopper portion 35 may be protruded from the second nut portion 32.
The screw 40 comprises a threaded section 400 and a polished rod section 401 which are arranged in sequence, the diameter of the polished rod section 401 is smaller than that of the threaded section 400, and the end part of the threaded section 400 penetrates out of the first support hole 120 and then is in transmission connection with the output shaft of the driving element 41. The pole segment 401 is arranged by the fifth magnetic element 14 in the second support 13.
When the second nut portion 32 moves from the threaded section 400 to the polished rod section 401 with the rotation of the screw 40, since the diameter of the polished rod section 401 is smaller than that of the threaded section 400, the second nut portion 32 is lowered.
As shown in fig. 12, the guide bar 5 includes a first horizontal bar portion 50, a second horizontal bar portion 51, and an inclined bar portion 52 inclined between the first horizontal bar portion 50 and the second horizontal bar portion 51. The diagonal portion 52 is located below the polished rod section 401, and the diagonal portion 52 is inclined obliquely downward.
When the second nut portion 32 moves from the threaded section 400 to the polished rod section 401 with the rotation of the screw 40, the second nut portion 32 slides down along the inclined rod section 52, thereby achieving sliding down along the guide rod 5.
In order to cooperate with the second nut portion 32 to slidably descend along the inclined rod portion 52, the second through hole 320 of the second nut portion 32 through which the guide rod 5 passes is a tapered hole extending in the axial direction. The taper of the tapered bore is adapted to the slope of the angled shaft portion 52.
In some embodiments, as shown in FIG. 13, the spray gun 3 further includes a guide post 36 secured to an outer surface of the spray gun body 30. The inner surface of the housing 10 is provided with a guide groove 101 which is slidably engaged with the guide post 36.
The guide post 36 and the guide groove 101 together form a guide structure which provides an effective guiding function when the spray gun 3 slides relative to the housing part 10.
The initial position of the spray gun assembly is shown in figure 1. When the driving element 41 drives the screw 40 to rotate in the forward direction, the first magnetic member 11 is attracted to the third magnetic member 22. Since the torque applied to the first nut portion 23 by the screw 40 is smaller than the magnetic attraction force between the first magnetic member 11 and the third magnetic member 22, the second housing 2 is restricted from moving by the magnetic attraction force, and the first nut portion 23 on the tubular portion 20 of the second housing 2 is not in threaded contact with the screw 40, so that the second housing 2 is not moved.
With the forward rotation of the screw 40, the lance 3 is pushed out of the second housing 2 by the second nut portion 32.
The spray gun 3 slowly extends out of the second casing 2, and after the fourth magnetic part 31 and the second magnetic part 21 are attracted, the spray gun 3 extends out to the limit position relative to the second casing 2.
Then, along with the forward rotation of the screw 40, the spray gun 3 pulls the second housing 2, so that the first magnetic part 11 and the third magnetic part 22 are disengaged, the first nut part 23 is in threaded connection with the screw 40, and the second housing 2 is driven by the first nut part 23 to extend out of the housing part 10.
Since the spray gun 3 is fixedly connected with the second housing 2 by the attraction of the fourth magnetic member 31 and the second magnetic member 21, the spray gun 3 moves continuously with the second housing 2.
As the screw 40 is rotated, the second nut portion 32 slides to the polished rod section 401, and at the same time, the second nut portion 32 slides down along the inclined rod portion 52. The sixth magnetic member 33 in the second nut portion 32 is attracted to the fifth magnetic member 14 in the second support portion 13, and the second nut portion 32 is stationary and does not slide.
The lance 3 and the second housing 2 continue to extend outwardly as the screw 40 rotates. Because the second nut portion 32 descends a small distance, the second position-limiting portion 35 of the torch body 30 can slide over the second nut portion 32, so that the torch 3 and the second housing 2 extend outward smoothly.
When the first nut portion 23 abuts on the second nut portion 32, the second housing 2 is extended to an extreme position with respect to the housing portion 10. The extending operation of the second housing 2 and the spray gun 3 is completed, and the spray gun 3 can perform the spray cleaning operation.
When the drive element 41 drives the screw 40 in reverse rotation, the lance 3 and the second housing 2 enter the return phase.
The second housing 2 is retracted into the housing portion 10 by the first nut portion 23.
Since the spray gun 3 is fixedly connected with the second housing 2 by the attraction of the fourth magnetic member 31 and the second magnetic member 21, the spray gun 3 starts a return motion with the second housing 2.
During the retraction movement of the torch 3 with the second housing 2, the first stopper portion 34 on the torch body 30 contacts the second nut portion 32.
As the screw 40 continues to rotate in the reverse direction, the second nut portion 32 rises along the inclined rod portion 52 and is finally caught in the space between the first stopper portion 34 and the second stopper portion 35 of the torch body 30. At the same time, the second nut portion 32 is again threadedly connected with the threaded section 400.
After the spray gun 3 moves back with the second housing 2 for a certain distance, the fourth magnetic member 31 and the second magnetic member 21 are disengaged because the torque applied to the second nut portion 32 by the screw 40 is greater than the magnetic attraction force between the fourth magnetic member 31 and the second magnetic member 21. As the screw 40 continues to rotate in the reverse direction, the lance 3 is retracted into the second housing 2 by the second nut portion 32.
As the first magnetic member 11 and the third magnetic member 22 are attracted, the second housing 2 is retracted into the housing portion 10. When the second nut portion 32 abuts against the first nut portion 23, the spray gun 3 is retracted into the second housing 2. Both the lance 3 and the second housing 2 are retracted to the initial position, awaiting the next extension command.
Intelligent closestool and spray gun subassembly in this application adopts second shell 2 and 3 two-stage extending structure of spray gun, has realized the flexible removal of low noise of spray gun, and occupation space is few to realize the motion control of second shell 2 and spray gun 3 through magnetism structure of inhaling.
