Detailed Implementation

[0023] Various exemplary embodiments of the present application will now be described in detail with reference to the accompanying drawings. It should be noted that, unless otherwise specifically stated, the relative arrangement, numerical expressions, and values ​​of the components and steps set forth in these embodiments do not limit the scope of the present application.

[0024] The following description of at least one exemplary embodiment is merely illustrative and is in no way intended to limit the scope of this application and its application or use.

[0025] Techniques, methods, and equipment known to those skilled in the art may not be discussed in detail, but where appropriate, they should be considered part of the specification.

[0026] In all the examples shown and discussed herein, any specific values ​​should be interpreted as merely exemplary and not as limitations. Therefore, other examples of exemplary embodiments may have different values.

[0027] Please refer to Figures 1 to 4 The quick-connect pipe fitting disassembly device provided in this application includes a positioning plate 100, a transmission device 200, and a pressure plate 300. The positioning plate 100 has a positioning hole 110. The transmission device 200 is connected to the positioning plate 100. The pressure plate 300 includes a first surface 310 and a second surface 320 disposed opposite to each other. The first surface 310 is connected to the transmission device 200, and the second surface 320 has a slot 321 formed by the recess of the second surface 320. The transmission device 200 can drive the pressure plate 300 to move closer to or away from the positioning plate 100.

[0028] As those skilled in the art know, the insertion distance of the quick-connect pipe connector 710 during the insertion process is very small, approximately 2-3 millimeters. Therefore, in this embodiment, the transmission device 200 only needs to move the pressure plate 300 by about 2-3 millimeters to disassemble the pipe connector 710. Those skilled in the art should also know that the insertion point of the pipe connector 710 has a groove. In this embodiment, the positioning block on the positioning plate 100 is first fitted onto the plug 720 of the cigarette machine's adhesive spraying pipe 700, and the slot 321 of the pressure plate 300 is engaged in the groove of the pipe connector 710. Then, the transmission device 200 drives the pressure plate 300 closer to the positioning plate 100, thereby applying a disassembly force to the pipe connector 710 to disassemble it. This avoids manual disassembly of the pipe connector 710, reducing the difficulty of disassembling the pipe connector 710 and improving disassembly efficiency. In this embodiment, the pressure plate 300 is driven by the transmission device 200 to disassemble the pipe joint 710, thereby avoiding direct force on the pipe joint 710 during the disassembly process. This facilitates operation and allows the user to apply force more easily.

[0029] Those skilled in the art will understand that the relative positions of the positioning hole 110 and the slot 321 can be set according to actual conditions, as long as it ensures that when the positioning hole 110 is fitted onto the plug 720 of the adhesive spraying pipe 700, the slot 321 can be engaged in the groove of the pipe connector 710. In this embodiment, the central axis of the positioning hole 110 is perpendicular to the second surface 320. Those skilled in the art will also understand that the positioning hole 110 does not necessarily have to be fitted onto the plug 720 of the adhesive spraying pipe 700; only a suitable positioning point is required. In this embodiment, since the cigarette machine's adhesive spraying pipe 700 has a plug 720, this embodiment is used as an example for illustration.

[0030] In one embodiment, the transmission device 200 includes a driving rod 220, a rocker arm 210, and a driven rod 230; the rocker arm 210 includes a first end and a second end disposed opposite to each other, the middle portion of the rocker arm 210 is hinged to the positioning plate 100, the rocker arm 210 is rotatable about the hinge point, and the rotation axis of the rocker arm 210 is parallel to the central axis of the positioning hole 110; the driving rod 220 includes a first end and a second end disposed opposite to each other, the middle portion of the driving rod 220 is hinged to the first end of the rocker arm 210, and the driving rod 220... The second end of the rod 230 is hinged to the first surface 310; the driven rod 230 includes a first end and a second end disposed opposite to each other, the first end of the driven rod 230 is hinged to the second end of the swing rod 210, and the second end of the driven rod 230 is hinged to the first surface 310; applying a force to the first end of the driving rod 220 to rotate the driving rod 220 about the hinge point between the driving rod 220 and the swing rod 210 can cause the driving rod 220 and the driven rod 230 to move the pressure plate 300 closer to or away from the pressure plate 300. In this embodiment, the user only needs to rotate the driving rod 220 at the first end of the driving rod 220 to move the pressure plate 300 closer to or away from the positioning plate 100, thereby facilitating user operation. In this embodiment, the driving rod 220 moves the driven rod 230 by rotating the swing rod 210, which is a clever design.

[0031] In one embodiment, the transmission device 200 further includes a first connecting rod 240 and a second connecting rod 250; the second end of the driving rod 220 is hinged to the first surface 310 via the first connecting rod 240, and both ends of the first connecting rod 240 are respectively hinged to the second end of the driving rod 220 and the first surface 310; the second end of the driven rod 230 is hinged to the first surface 310 via the second connecting rod 250, and both ends of the second connecting rod 250 are respectively hinged to the second end of the driven rod 230 and the first surface 310. Those skilled in the art will understand that by providing the first connecting rod 240 and the second connecting rod 250, the mutual constraint between the connecting rods can prevent the pressure plate 300 from moving in a direction perpendicular to the pressure plate 300 and close to the positioning plate 100, thereby ensuring that the pressure plate 300 only moves in a direction close to or away from the positioning plate 100.

[0032] It should be noted that, as Figure 2 As shown, when the first link 240, the pressure plate 300, and the second link 250 are collinear, this is called an indeterminate state. In this state, when the driving rod 220 is rotated, the direction of movement of the pressure plate 300 is uncertain. The pressure plate 300 may retract inwards, i.e., move towards the positioning plate 100; or it may extend outwards, i.e., move away from the positioning plate 100. Therefore, in actual use, the initial position of the pressure plate 300 is either in the retracted state, such as... Figure 3As shown; it is either in an abducted state, such as Figure 1 As shown, this ensures that the pressure plate 300 can move in the required direction when the active rod 220 is rotated. Those skilled in the art will understand that whether the pressure plate 300 is in a retracted or extended state can be determined by the distance between the plug 720 and the pipe connector 710 on the adhesive spraying pipe 700. If the distance is small, the initial state of the pressure plate 300 can be a retracted state; conversely, if the distance is large, it is an extended state. In this embodiment, this configuration allows for flexible application to different distances between the plug 720 and the pipe connector 710 of the adhesive spraying pipe 700, increasing the applicability of the quick-connect pipe connector 710 disassembly device provided in this embodiment.

[0033] In one embodiment, the quick-connect pipe fitting 710 disassembly device further includes a power unit 400, which is connected to the positioning plate 100. The drive end of the power unit 400 drives the first end of the active rod 220. In this embodiment, the active rod 220 is moved by the power unit 400, which is convenient and quick.

[0034] In one embodiment, the power unit 400 includes a transmission rod 410 and a drive unit 420. The first end of the transmission rod 410 is hinged to the first end of the drive rod 220. The drive unit 420 is connected to the positioning plate 100, and its drive end is drivenly connected to the second end of the transmission rod 410. The drive unit 420 and the positioning plate 100 are integrated, facilitating overall movement. In this embodiment, since the drive rod 220 needs to rotate around the hinge point between the drive rod 220 and the swing rod 210, the first end of the transmission rod 410 is hinged to the first end of the drive rod 220 to avoid interference with the movement of the drive rod 220. In this embodiment, the first end of the active rod 220 moves in a straight line under the drive of the transmission rod 410. Since the swing rod 210 is hinged to the positioning plate 100, when the first end of the active rod 220 moves up and down under the drive of the transmission rod 410, the swing rod 210 will rotate around the hinge point between the swing rod 210 and the positioning plate 100, thereby preventing the active rod 220 from getting stuck.

[0035] In one embodiment, the driving device 420 includes an adjusting rod 430; the adjusting rod 430 includes an adjusting section 431 and a snap-fit ​​section 432 fixedly connected, the adjusting section 431 having an internal thread at one end away from the snap-fit ​​section 432, the snap-fit ​​section 432 including a first snap-fit ​​platform 433, a snap-fit ​​post, and a second snap-fit ​​platform 434 fixedly connected in sequence, the adjusting section 431 being fixedly connected to the end of the second snap-fit ​​platform 434 away from the first snap-fit ​​platform 433; the second end of the transmission rod 410 has an external thread 411; the positioning plate 100 includes a positioning part 120 and a snap-fit ​​part 130, the positioning part 120 including a third surface disposed opposite to each other. The third surface 121 and the fourth surface, and the fifth surface 122 connecting the third surface 121 and the fourth surface, the positioning hole 110 is located on the fourth surface, and the rocker arm 210 is hinged to the third surface 121; the snap-fit ​​part 130 is fixedly connected to the fifth surface 122, and a first groove is provided at the end of the snap-fit ​​part 130 away from the fifth surface 122; the snap-fit ​​post is located in the first groove, the first snap-fit ​​platform 433 and the second snap-fit ​​platform 434 are respectively located on both sides of the first groove, the external thread 411 is screwed to the internal thread, and the adjusting rod 430 can be turned so that the transmission rod 410 can move along the axial direction of the transmission rod 410. Those skilled in the art will understand that by setting the hinge point of the rocker arm 210 and the positioning hole 110 on different surfaces, in use, the positioning hole 110 on the fourth surface is fitted onto the plug 720 of the adhesive spraying pipe 700, thereby avoiding interference of the rocker arm 210 and facilitating operation.

[0036] In this embodiment, when the adjusting rod 430 is rotated, since the adjusting rod 430 and the transmission rod 410 are screwed together, the adjusting rod 430 and the transmission rod 410 will move relative to each other. The locking pin of the adjusting rod 430 is located in the first groove, and the first locking platform 433 and the second locking platform 434 are located on opposite sides of the first groove. Therefore, due to the restriction of the first locking platform 433 and the upper and lower walls of the first groove, the adjusting rod 430 will not move axially. Consequently, when the adjusting rod 430 is rotated, the transmission rod 410 will move axially along the adjusting rod 430, thereby driving the drive rod 220 to move.

[0037] In one embodiment, the positioning plate 100 further includes a limiting portion 140, which is fixedly connected to the fifth surface 122. The limiting portion 140 has a through hole, and at least part of the end of the adjusting section 431 away from the locking section 432 is located in the through hole. In this embodiment, by providing a through hole in the limiting portion 140, radial movement of the adjusting rod 430 can be avoided, thereby ensuring that when the adjusting rod 430 is rotated, the transmission rod 410 can only move axially along the adjusting rod 430.

[0038] In one embodiment, the quick-connect fitting 710 disassembly device further includes a connecting block 500, which has a second groove. The connecting block 500 is fixedly connected to the snap-fit ​​portion 130, and the first groove and the second groove surround the snap-fit ​​post. This arrangement prevents the snap-fit ​​post from falling out of the first groove. Those skilled in the art will understand that the connecting block 500 can be fixedly connected to the snap-fit ​​portion 130 by bolts.

[0039] In one embodiment, at least one of the first locking plate 433 and the second locking plate 434 is multifaceted. Those skilled in the art will understand that the first locking plate 433 or the second locking plate 434 can be shaped like a hexagonal nut 600. This arrangement facilitates the user's use of tools to rotate the adjusting rod 430, such as a wrench.

[0040] In another embodiment, the driving device 420 includes a telescopic motor; the telescopic motor is fixed to the positioning plate 100, and the driving end of the telescopic motor is connected to the transmission rod 410. In this embodiment, an electric telescopic motor is used for driving, which can save the physical strength of the user. Those skilled in the art will understand that a battery can also be provided on the third surface 121 of the positioning plate 100 for driving the telescopic motor.

[0041] In one embodiment, the positioning hole 110 extends from the fourth surface to the third surface 121. This arrangement facilitates observation.

[0042] Those skilled in the art will also know that all the hinges in the embodiments of this application can be implemented using pins and nuts, and the specific implementation methods are existing technologies, which will not be described in detail here.

[0043] While specific embodiments of this application have been described in detail by way of examples, those skilled in the art should understand that the above examples are for illustrative purposes only and are not intended to limit the scope of this application.
