As shown in fig. 1 to 12, an embodiment of the present invention provides a multifunctional dismounting tool for a nozzle assembly, which includes a barrel 100, a clamping mechanism 200, a locking pin 900, a housing 400, and a force-releasing ring 300; wherein, the barrel 100 is axially provided with a containing hole 110, the barrel 100 is radially provided with a first locking hole 150, and the side wall of the barrel 100 is provided with a first elastic positioning mechanism 700; the clamping mechanism 200 is rotatably arranged in the accommodating hole 110, a plurality of straight clips 210 are arranged on the clamping mechanism 200, the plurality of straight clips 210 are uniformly distributed on the circumferential surface, and a second locking hole 221 is arranged in the radial direction of the clamping mechanism 200; the locking pin 900 penetrates through the first locking hole 150, or the locking pin 900 penetrates through the first locking hole 150 and the second locking hole 221 in sequence; the shell 400 is arranged in the accommodating hole 110, the shell 400 is connected with the clamping mechanism 200, an accommodating space is arranged in the shell 400, the straight-going clamping pieces 210 are arranged in the accommodating space, the outer side surfaces of the straight-going clamping pieces 210 are abutted against the inner wall of the accommodating space, and a clamping space for clamping the nozzle 1 is formed between the inner side surfaces of the straight-going clamping pieces 210; the force-releasing ring 300 is arranged in the accommodating hole 110, a plurality of positioning holes 320 are uniformly arranged on the side wall of the force-releasing ring 300, the positioning holes 320 are matched with the first elastic positioning mechanism 700, and the force-releasing ring 300 is also provided with a mounting hole 310 used for being matched with the nozzle base 2.

The existing high-pressure micro-mist nozzle assembly generally comprises a base 2 and a nozzle 1, wherein one end of the base 2 is in threaded connection with the nozzle 1, the other end of the base 2 is provided with a stud 3 for connecting with equipment, and the high-pressure micro-mist nozzle assembly is mounted or dismounted by applying torque force to the base 2. The base 2 is generally a hexagonal cylinder, and in this embodiment, the mounting hole 310 of the force-releasing ring 300 may also be a hexagonal hole that is matched with the hexagonal cylinder in order to be matched with the base 2.

When the nozzle assembly needs to be disassembled, the cylinder body 100 in this embodiment may be connected to the driving mechanism, and the other end of the cylinder body 100 is connected to the base 2 through the mounting hole 310 on the force-releasing ring 300, and at the same time, the nozzle 1 may pass through the mounting hole 310 and then extend into the clamping space formed between the inner side surfaces of the straight clips 210. Wherein, the clamping space is a space with approximate hole shape, the diameter of the clamping space is slightly smaller than the outer diameter of the nozzle 1, when the nozzle 1 is inserted into the clamping space, each of the clips 210 can be pressed, the pressed clips 210 are twisted and inclined at a certain angle, that is, one straight traveling jaw 210 is pressed and twisted close to an adjacent straight traveling jaw 210, meanwhile, part of the straight clips 210 have a tendency of expanding outward in the radial direction after being extruded, but are blocked by the housing 400, and the straight clips 210 are simultaneously extruded by the housing 400 and the nozzle 1 and then elastically deformed, so that the extrusion force of the straight clips 210 on the nozzle 1 is increased, thereby can promote the tight fixity of clamp to nozzle 1, when base 2 is pulled down from equipment, through the centre gripping of craspedodrome clamping piece 210 to nozzle 1, can make whole high pressure little fog nozzle assembly can not drop from this assembly and disassembly tools.

In the dismounting process, the cylinder 100 can be driven to rotate by the driving mechanism, the cylinder 100 drives the force-unloading ring 300 to synchronously rotate, so that the base 2 can be driven to rotate by the force-unloading ring 300 to realize the dismounting of the base 2, and the nozzle 1 is fixed on the base 2, so that the base 2 and the nozzle 1 can be integrally dismounted simultaneously when the base 2 is dismounted.

Conversely, when it is desired to install the nozzle assembly on the apparatus, the barrel 100 may be driven in a reverse direction to gradually tighten the stud 3 on the base 2 onto the apparatus. When the base 2 reaches a preset torque value in the installation process, the base 2 cannot continue to rotate, the barrel 100 still rotates under the action of the driving mechanism at the moment, and the force unloading ring 300 also has a tendency of rotating relative to the base 2; because the force-releasing ring 300 is fixedly connected with the base 2 through the mounting hole 310, the force-releasing ring 300 is restrained by the base 2 and can not rotate, at this time, torsion is generated between the rotating cylinder 100 and the stationary force-releasing ring 300, so that the part of the first elastic positioning mechanism 700, which is matched with the positioning hole 320, is moved out of the positioning hole 320 under the action of the torsion, so that the first elastic positioning mechanism 700 slightly retracts, at this time, the cylinder 100 can continuously rotate relative to the force-releasing ring 300, and when the first elastic positioning mechanism 700 reaches the next positioning hole 320, the first elastic positioning mechanism 700 can be matched with the positioning hole 320 again, and at the same time, the first elastic positioning mechanism 700 can impact the edge of the positioning hole 320, and can transmit the striking sense generated by the impact to the operator, and simultaneously generate striking sound, the operator can clearly judge that the base 2 is mounted through the sensing and sound, and stops the operation of the driving mechanism. Of course, since the driving mechanism drives the barrel 100 to rotate at a higher speed, when the operator recognizes that the preset torque is reached, the first elastic positioning mechanism 700 may be engaged with and disengaged from the plurality of positioning holes 320, and may make a sound of multiple impacts, so that the operator may accurately determine that the base 2 has reached the preset torque. In addition, through the cooperation of the first elastic positioning mechanism 700 and the force unloading ring 300, the torsion from the cylinder body 100 is released when the preset torque is reached, and the phenomenon that the driving mechanism is locked due to the clamping between the force unloading ring 300 and the cylinder body 100 when the preset torque is reached can be avoided.

In addition, when the nozzle assembly is installed, when the nozzle assembly reaches a preset torque, the base 2 does not rotate, but the barrel 100 continues to rotate, if the clamping mechanism 200 is fixedly connected with the barrel 100, the clamping mechanism 200 rotates along with the barrel 100, and since the straight clamping pieces 210 on the clamping mechanism 200 are clamped on the nozzle 1, when the clamping mechanism 200 rotates, continuous sliding friction occurs between the straight clamping pieces 210 and the nozzle 1, accelerated wear of the nozzle 1 is caused, and the service life of the nozzle 1 is reduced. For this reason, in the present embodiment, the clamping mechanism 200 is rotatably disposed in the accommodating hole 110 of the barrel 100, that is, the clamping mechanism 200 and the barrel 100 can rotate relatively, that is, when the barrel 100 rotates, the clamping mechanism 200 is kept still by the action of the large static friction between the nozzle 1 and the nozzle 1, so that the abrasion of the straight clip 210 to the nozzle 1 can be completely avoided, and the service life of the nozzle 1 is prolonged.

In the above description, the nozzle base 2 is detached or attached, and the nozzle 1 is fixed to the base 2, so that the base 2 and the nozzle 1 can be integrally detached when the base 2 is detached. In the process of disassembling and assembling the base 2, the locking pin 900 is only inserted into the first locking hole 150, and does not extend into the second locking hole 221.

When only the nozzle 1 needs to be disassembled and assembled, the force-releasing ring 300 can be removed from the dual-purpose disassembling and assembling tool, that is, the connection of the force-releasing ring 300 and the base 2 is not needed, but the nozzle 1 is directly inserted into the clamping space formed between the inner side surfaces of the plurality of straight clips 210 for clamping the nozzle 1, and the clamping of the nozzle 1 is realized through the cooperation of the straight clips 210 and the shell 400. Then, the locking pin 900 can be simultaneously inserted into the first locking hole 150 and the second locking hole 221 to achieve relative fixation between the cylinder 100 and the clamping mechanism 200, so that in the process of driving the cylinder 100 to rotate, the clamping mechanism 200 can be driven to synchronously rotate through the locking pin 900, thereby driving the nozzle 1 to synchronously rotate, and realizing the dismounting and mounting of the nozzle 1 on the base 2.

That is, when the base 2 is not damaged but the nozzle 1 is damaged, the removal of the nozzle 1 can be achieved by the simultaneous rotation of the clamping mechanism 200, the locking pin 900 and the cylinder 100 without removing the base 2; when the base 2 is damaged, the base 2 can be detached through the cooperation of the force-releasing ring 300, the clamping mechanism 200 and the cylinder 100. From this, this dual-purpose assembly and disassembly tools has realized the selective dismouting to nozzle base 2 or nozzle 1, has promoted dismouting efficiency, has also reduced the damage that the dismouting in-process caused.

Specifically, the first locking hole 150 includes a lateral groove portion 152 and a straight hole portion 151, the straight hole portion 151 penetrates through the sidewall of the cylinder 100, the lateral groove portion 152 is recessed inward from the sidewall surface of the cylinder 100, and one end of the lateral groove portion 152 is vertically communicated with one end of the straight hole portion 151; the locking pin 900 includes locking section 910 and bending section 920, and locking section 910 and bending section 920 rotate to be connected, and when the bending section 920 rotated to the collinear position with locking section 910, locking section 910 wore to establish to the second locking hole 221 in, and bending section 920 wore to establish to straight hole portion 151 in to can make barrel 100 and clamping mechanism 200 relatively fixed, in order to realize the dismouting to nozzle 1. The locking segment 910 can be completely or partially inserted into the second locking hole 221, and after the bending segment 920 is inserted into the straight hole 151, the end of the bending segment 920 will not protrude out of the surface of the sidewall of the cylinder 100.

And when the bending section 920 rotates to the position perpendicular to the locking section 910, the locking section 910 penetrates through the straight hole portion 151, the bending section 920 is clamped in the transverse groove portion 152, and at this time, the locking section 910 does not penetrate through the second locking hole 221, so that the cylinder 100 and the clamping mechanism 200 can rotate relatively to realize the disassembly and assembly of the nozzle base 2. After the bending section 920 is clamped in the transverse groove portion 152, the surface of the bending section 920 and the surface of the sidewall of the cylinder 100 may form a complete arc surface.

In order to ensure that the locking pin 900 can be fastened in the second locking hole 221 and prevent the locking pin 900 from falling off during the synchronous rotation of the barrel 100 and the clamping mechanism 200, a partial internal thread may be provided in the second locking hole 221, and a partial external thread may be provided on the locking section 910 of the locking pin 900, so that the locking pin 900 can be fastened in the second locking hole 221 through the cooperation of the internal thread and the external thread. Of course, a partial internal thread may be provided in the first locking hole 150, and the locking section 910 may be screwed with the first locking hole 150, thereby preventing the locking pin 900 from falling off when the cylinder 100 is rotated alone.

A plurality of second locking holes 221 may be uniformly arranged in the circumferential direction of the clamping mechanism 200, so that the alignment of the first locking hole 150 and the second locking hole 221 can be achieved by rotating the cylinder 100 by a small angle.

Wherein, be provided with inclined plane or arcwall face 211 on the fastener 210 of going straight for the direction is provided to the insertion of nozzle 1, is convenient for nozzle 1 to insert to the tight space of clamp that is formed by each fastener 210 of going straight, also is convenient for nozzle 1 to extrude fastener 210 of going straight gradually at the insertion in-process simultaneously, makes it take place elastic deformation to press from both sides tight nozzle 1.

Further, in order to improve the clamping force of the straight clips 210 on the nozzle 1, the straight clips 210 are provided with wear-resistant coating glue.

In the embodiment, in order to realize that the rectilinear clip 210 has certain elasticity, so as to clamp the nozzle 1 through elastic deformation of the rectilinear clip 210, and simultaneously ensure that the rectilinear clip 210 has certain strength, and cannot be worn and broken after long-term use, the rectilinear clip 210 is preferably a copper sheet.

Specifically, the first elastic positioning mechanism 700 includes a spacing post 730, a first spring 720 and a first locking bolt 710; the side wall of the barrel 100 is provided with a first limiting hole 130, the limiting column 730 is arranged in the first limiting hole 130, the limiting end of the limiting column 730 extends out of the first limiting hole 130 and then is matched with the positioning hole 320 on the force-removing ring 300, two ends of the first spring 720 are respectively abutted against the limiting column 730 and the first locking bolt 710, and the first locking bolt 710 is fixedly connected with the first limiting hole 130.

After the positioning hole 320 of the force-releasing ring 300 is aligned with the limiting post 730, the limiting end of the limiting post 730 can be pressed against the positioning hole 320 by the elastic force of the spring, so that the force-releasing ring 300 is positioned in the cylinder 100, and the force-releasing ring 300 can rotate along with the cylinder 100.

When the nozzle assembly is installed on the apparatus, when the nozzle assembly is tightened to a predetermined torque, the force-releasing ring 300 is restrained by the nozzle base 2 and does not rotate any more, at this time, as the barrel 100 continues to rotate, a torsion force is generated between the barrel 100 and the force-releasing ring 300, the torsion force acts on the position-limiting post 730, and the torsion force generates a component force in the axial direction of the position-limiting post 730 to push the position-limiting post 730 to disengage from the position-limiting hole 320, and after the position-limiting post 730 is completely disengaged from the position-limiting hole 320, the position-limiting post 730 keeps contact with the side wall of the force-releasing ring 300 except the position-limiting hole 320 under the action of the spring, and as the barrel 100 rotates, the position-limiting end of the position-limiting post 730 slides on the side wall of the force-releasing ring 300, until the position-limiting post 730 reaches the next position-limiting hole 320, the position-limiting end of the position-limiting post 730 can be re-matched with the current position, the vibration touch feeling and the collision sound are brought to an operator, so that the operator is reminded that the nozzle assembly is installed; meanwhile, the matching mode of the limiting column 730 and the positioning hole 320 can realize automatic force unloading when the preset torque is reached, and the clamping stagnation problem is avoided.

The first limiting hole 130 is a tapered hole, the limiting column 730 is a tapered column matched with the tapered hole, and the end surface of the limiting column 730 is a spherical surface.

The tapered shape of the limiting post 730 means that the diameter of the limiting post 730 is gradually reduced toward the direction of the limiting end, and when the limiting post 730 is engaged with the first limiting hole 130, the limiting post 730 can be prevented from automatically falling off from the first limiting hole 130; by setting the end surface of the position-limiting post 730 to be a spherical surface, when a torque force is generated between the force-releasing ring 300 and the barrel 100, a component force for pushing the position-limiting post 730 is generated after the inner wall of the positioning hole 320 contacts the spherical surface, so as to avoid the clamping stagnation between the positioning hole 320 and the position-limiting post 730.

Further, the positioning hole 320 includes a conical surface 322 and a cylindrical surface 321, the conical surface 322 and the cylindrical surface 321 are two opposite surfaces in the positioning hole 320, and the conical surface 322 and the cylindrical surface 321 are both disposed in the rotation direction of the force-removing ring 300, where the conical surface 322 indicates that an acute angle is formed between an inner surface in the positioning hole 320 and the axis direction, and the cylindrical surface 321 indicates that the inner surface in the positioning hole 320 is parallel to the axis direction.

When the nozzle 1 needs to be disassembled, the barrel 100 drives the force-releasing ring 300 to rotate through the limiting column 730, and at the moment, the limiting column 730 is always attached to the cylindrical surface 321 in the positioning hole 320, so that a tangential force which can drive the force-releasing ring 300 to rotate is generated on the side wall of the positioning hole 320, a component force in the radial direction of the force-releasing ring 300 cannot be generated, the force-releasing ring 300 can be ensured to rotate reliably, and the nozzle 1 can be disassembled.

When the nozzle 1 needs to be installed, the barrel 100 drives the force-discharging ring 300 to rotate through the limiting column 730, at the moment, the spherical surface of the limiting column 730 is always in contact with the conical surface 322 in the positioning hole 320, at the moment, the spherical surface of the limiting column 730 can generate a tangential force for driving the force-discharging ring 300 to rotate on the conical surface 322, and meanwhile, a radial force for pushing the limiting column 730 to be far away from the force-discharging ring 300 can be generated, when the base 2 of the nozzle 1 does not reach a preset torque, the tangential force can always drive the force-discharging ring 300 to rotate, and the limiting column 730 cannot be pushed out of the positioning hole 320 by the radial force; when the base 2 of the nozzle 1 reaches the preset torque, the force-releasing ring 300 does not rotate, and the radial force can push out the limit column 730 to release the force.

Further, as shown in fig. 4, the receiving hole 110 includes a first hole 111 and a second hole 112, the diameter of the first hole 111 is larger than the diameter of the second hole 112, the force-releasing ring 300 is disposed in the first hole 111, the clamping mechanism 200 and the housing 400 are disposed in the second hole 112, and the first stopper hole 130 communicates with the first hole 111.

When the nozzle assembly reaches a preset torque during installation, the continuous rotation of the barrel 100 can cause the limit column 730 to be continuously clamped and separated with the plurality of positioning holes 320 until the driving mechanism stops; the long-term collision, engagement or disengagement between the positioning hole 320 and the position-limiting post 730 will cause accelerated wear of the positioning hole 320, and the positioning hole 320 will not receive enough tangential force to drive the force-releasing ring 300 to rotate. In order to reduce the abrasion to the positioning hole 320, when the nozzle assembly is installed to reach a preset torque, an operator can apply a certain thrust to the barrel 100 in the direction of the nozzle assembly when hearing the sound generated by the collision of the first sound or the second sound limiting column 730 with the positioning hole 320, when the limiting column 730 rotates along with the barrel 100 and contacts with the part outside the positioning hole 320, the barrel 100 moves axially relative to the force-releasing ring 300 under the action of the thrust, and the moving distance is less than or equal to the gap 113, so that the axial dislocation of the force-releasing ring 300 of the limiting column 730 relative to the positioning hole 320 can be caused, and the limiting column 730 does not engage with or separate from the subsequent positioning hole 320 along with the rotation of the barrel 100 until the driving mechanism stops; thereby reducing the matching times of the limiting column 730 and the positioning hole 320, effectively reducing the abrasion on the positioning hole 320 and prolonging the service life.
