Detailed Implementation

[0028] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0029] Please see Figure 1-5 A small mobile single-clamp loading and unloading smoke device includes a base plate 1, a support plate 2 is provided above the base plate 1, two placement rods 3 are symmetrically and detachably provided on one side of the support plate 2, and a lifting and rotating assembly 4 is provided on the base plate 1 for driving the support plate 2 to lift and rotate.

[0030] The lifting and rotating assembly 4 includes a support plate 41 disposed above the base plate 1, a rotating assembly 42 disposed inside the base plate 1 to drive the support plate 41 to rotate, a vertical tube 43 with a square cross-section fixedly connected above the support plate 41, a threaded rod 44 rotatably disposed on the inner wall of the bottom of the vertical tube 43, a threaded sleeve 45 threadedly connected to the other end of the threaded rod 44, the threaded sleeve 45 with a square outer shape and slidably disposed inside the vertical tube 43, the top end of the threaded sleeve 45 being fixedly connected to the support plate 2, and a driving assembly 46 disposed on the support plate 41 to drive the threaded rod 44 to rotate.

[0031] This design, through the setting of the lifting and rotating component 4, not only allows for flexible adjustment of the height of the placement rod 3 as needed, making it convenient for people of different heights to hang or remove cigarette clips, thus improving comfort and convenience; it also allows for changing the orientation of the support plate 2 and the placement rod 3, effectively solving the problem that the angle of the cigarette clip cannot be automatically adjusted during the hanging or removal of the cigarette clip, requiring frequent manual adjustment of the entire device's position and angle, which is inconvenient to use. This makes the loading and unloading of cigarette clips smoother and allows for precise loading and unloading at different positions.

[0032] The drive assembly 46 includes a first motor 461 fixedly mounted on the top of the support plate 41. The power output end of the first motor 461 extends through the vertical tube 43 into its interior and is connected to a first bevel gear 462. A second bevel gear 463 is fixedly sleeved on the threaded rod 44. The first bevel gear 462 and the second bevel gear 463 are meshed together.

[0033] When the height of the placement rod 3 needs to be adjusted, the first motor 461 is started first. The first motor 461 starts running and drives the first bevel gear 462, which is connected to it, to start rotating. Since the first bevel gear 462 is meshed with the second bevel gear 463, which is fixedly sleeved on the threaded rod 44, when the first bevel gear 462 rotates, according to the transmission characteristics of the bevel gear, it will drive the second bevel gear 463 to rotate, thereby causing the threaded rod 44 to start rotating. Since the threaded sleeve 45 is square on the outside and is slidably set in the vertical tube 43, the threaded sleeve 45 will rise or fall in the vertical tube 43, causing the support plate 2, which is fixedly connected to it, to change its height, thereby changing the height of the placement rod 3, and thus adapting to the loading and unloading needs of different heights.

[0034] The rotating assembly 42 includes a slot 421 formed inside the base plate 1. A worm gear 422 is rotatably disposed inside the slot 421. One end of the worm gear 422 is rotatably connected to the inner wall of the slot 421, and the other end of the worm gear 422 is drivenly connected to a second motor 423. The second motor 423 is fixedly mounted on the base plate 1.

[0035] The top of the base plate 1 is rotatably fitted with a rotating rod 424. The top end of the rotating rod 424 is fixedly connected to the support plate 41. The bottom end of the rotating rod 424 extends through the top of the base plate 1 into the slot 421 and is fixedly connected to a worm gear 425. The worm 422 is meshed with the worm gear 425.

[0036] When the angle of the placement rod 3 needs to be adjusted, the second motor 423 is started. The second motor 423 drives the worm gear 422, which is connected to it, to start rotating in the slot 421 inside the base plate 1. As the worm gear 422 rotates, it meshes with the worm wheel 425, which is fixedly connected to the bottom end of the rotating rod 424. According to the transmission principle of the worm gear 422 and the worm wheel 425, the rotation of the worm gear 422 will drive the worm wheel 425 to rotate.

[0037] The rotating rod 424 rotates along with the worm gear 425. Since the top of the rotating rod 424 is fixedly connected to the support plate 41, the support plate 41 will rotate synchronously with the rotating rod 424, which will drive the vertical pipe 43, threaded sleeve 45, support plate 2 and placement rod 3 installed above the support plate 41 to rotate together, thereby realizing the adjustment of the angle of the support plate 2, and thus realizing the adjustment of the angle of the placement rod 3.

[0038] During rotation, the rotation direction and duration of the second motor 423 can be controlled according to actual needs, thereby precisely adjusting the support plate 2 to a suitable angle position to meet different loading and unloading requirements.

[0039] Two threaded sleeves 5 are symmetrically fixedly connected to one side wall of the support plate 2. Each threaded sleeve 5 is threaded with a threaded connector 6. The end of the threaded connector 6 away from the threaded sleeve 5 is integrally connected to the placement rod 3.

[0040] This design ensures that, firstly, the threaded connection between the screw sleeve 5 and the threaded connector 6 makes the connection between the placement rod 3 and the support plate 2 stable, and can withstand the weight of the cigarette clamp and external force when loading and unloading cigarettes, preventing the placement rod 3 from loosening or shaking.

[0041] Secondly, during installation, simply align the threaded connector 6 with the threaded sleeve 5 and rotate it. No complicated tools or skills are required. This saves time and manpower and improves efficiency when assembling the equipment or replacing the placement rod 3. When disassembling, simply rotate it in the opposite direction to remove it. This makes it easy to replace it in time if it is damaged, without affecting the use of the device. When the placement rod 3 is not in use, it can also be removed to reduce the space occupied, which is beneficial for equipment maintenance and upgrades.

[0042] A push handle assembly 7 is provided on one side of the top of the base plate 1. The push handle assembly 7 includes two fixed tubes 71 that are symmetrically fixedly installed on the top of the base plate 1. Vertical rods 72 are slidably sleeved inside each fixed tube 71. The tops of the two vertical rods 72 extend to the outside of the fixed tubes 71 and are fixedly connected to the same push rod 73.

[0043] Multiple locking holes 74 are evenly provided on one side wall of the vertical rod 72 along its height direction. A fixing hole 75 is provided on the side wall of the fixing tube 71 corresponding to the locking hole 74. A locking rod 76 is slidably inserted into the fixing hole 75. One end of the locking rod 76 is engaged with the locking hole 74, and the other end of the locking rod 76 is fixedly connected to a pull plate 77.

[0044] A tension spring 78 is fitted on the lever 76, and the two ends of the tension spring 78 are fixedly connected to the pull plate 77 and the fixing tube 71, respectively.

[0045] When the operator needs to adjust the height of the push handle, first hold the pull plate 77 and pull it outward. The movement of the pull plate 77 causes the locking rod 76 to slide outward in the fixing hole 75. The locking rod 76 gradually disengages from the locking hole 74 of the vertical rod 72. During this process, the tension spring 78 is stretched and stores elastic potential energy.

[0046] After the locking rod 76 disengages from the locking hole 74, the vertical rod 72 is in a freely sliding state within the fixed tube 71. Subsequently, the operator can push or pull the vertical rod 72 upwards or downwards according to their own needs or the requirements of the work scenario. The vertical rod 72 slides along the inner wall of the fixed tube 71 until it is adjusted to a suitable height position. During this process, the operator can determine the range of height adjustment by observing the locking hole 74 on the vertical rod 72.

[0047] Once the vertical rod 72 reaches the desired height, the operator releases the pull plate 77. Due to the restoring force generated by the previously stretched spring 78, it pulls the locking rod 76 into the fixing tube 71. The locking rod 76 is then reinserted into the corresponding locking hole 74 of the vertical rod 72, thereby fixing the vertical rod 72 back to the new height position.

[0048] This design allows for convenient and quick adjustment of the height of the push rod 73, thus accommodating not only operators of different heights but also various work scenarios.

[0049] The base plate 1 is equipped with universal wheels 8 with braking devices at each of the four corners at the bottom.

[0050] This design, with the universal wheels 8, makes it easy to move the loading and unloading smoke device to the required position. The braking device stops the universal wheels 8 from rotating and quickly fixes the device, ensuring stability during loading and unloading of smoke and preventing movement caused by collisions or uneven ground, thus ensuring operational accuracy and safety.

[0051] When in use, the operator adjusts the height of the push handle assembly 7 according to their own height. First, they hold the pull plate 77 and pull it outward. The movement of the pull plate 77 causes the locking rod 76 to slide outward in the fixing hole 75. The locking rod 76 gradually disengages from the locking hole 74 of the vertical rod 72. During this process, the tension spring 78 is stretched and stores elastic potential energy.

[0052] After the locking rod 76 disengages from the locking hole 74, the vertical rod 72 is in a freely sliding state within the fixed tube 71. Subsequently, the operator can push or pull the vertical rod 72 upwards or downwards according to their own needs or the requirements of the work scenario. The vertical rod 72 slides along the inner wall of the fixed tube 71 until it is adjusted to a suitable height position. During this process, the operator can determine the range of height adjustment by observing the locking hole 74 on the vertical rod 72.

[0053] Once the vertical rod 72 reaches the desired height, the operator releases the pull plate 77. Due to the restoring force generated by the previously stretched spring 78, it pulls the locking rod 76 into the fixing tube 71. The locking rod 76 is then reinserted into the corresponding locking hole 74 of the vertical rod 72, thereby fixing the vertical rod 72 back to the new height position.

[0054] Then push the push handle assembly 7, and the caster wheel 8 will move the loading and unloading smoke device to the appropriate position, and then lock the caster wheel 8.

[0055] When the height of the placement rod 3 needs to be adjusted, the first motor 461 is started. The rotation of the first motor 461 drives the first bevel gear 462 to rotate. Since the first bevel gear 462 and the second bevel gear 463 are meshed, the first bevel gear 462 drives the second bevel gear 463 to rotate synchronously, which in turn drives the threaded rod 44 to rotate.

[0056] Since the threaded sleeve 45 is threadedly connected to the threaded rod 44 and is slidably disposed inside the vertical tube 43, as the threaded rod 44 rotates, the threaded sleeve 45 will rise or fall inside the vertical tube 43, causing the support plate 2 fixedly connected to it to change its height, thereby changing the height of the placement rod 3, and thus adapting to the loading and unloading needs of different heights.

[0057] When the angle of the placement rod 3 needs to be adjusted, the second motor 423 is started. The second motor 423 drives the worm gear 422, which is connected to it, to start rotating in the slot 421 inside the base plate 1. As the worm gear 422 rotates, it meshes with the worm wheel 425, which is fixedly connected to the bottom end of the rotating rod 424. According to the transmission principle of the worm gear 422 and the worm wheel 425, the rotation of the worm gear 422 will drive the worm wheel 425 to rotate.

[0058] The rotating rod 424 rotates along with the worm gear 425. Since the top of the rotating rod 424 is fixedly connected to the support plate 41, the support plate 41 will rotate synchronously with the rotating rod 424, which will drive the vertical pipe 43, threaded sleeve 45, support plate 2 and placement rod 3 installed above the support plate 41 to rotate together, thereby realizing the adjustment of the angle of the support plate 2, and thus realizing the adjustment of the angle of the placement rod 3, thereby meeting the needs of different loading and unloading operations.

[0059] For those skilled in the art, any changes, modifications, substitutions, and variations made to the implementation methods without departing from the principles and spirit of this utility model, based on the teachings of this utility model, still fall within the protection scope of this utility model.
