Description

Technical Field

[0001] This utility model relates to the field of gas separation technology, specifically to a nitrogen generator that is easy to transport. Background Technology

[0002] Easy-to-transport nitrogen generators can overcome the handling limitations of traditional nitrogen generators through structural optimization, while meeting the nitrogen production function. This allows for flexible deployment and efficient operation in different scenarios, thus balancing the needs for nitrogen production capacity and portability.

[0003] In the prior art, a nitrogen generator that is easy to transport is disclosed in patent publication number CN219906996U. It includes a base box, a fixed box fixed on the base box, a moving mechanism inside the base box, a buffer assembly inside the fixed box, a fixed plate on the buffer assembly, a nitrogen generator body attached to the fixed plate, a base fixed below the nitrogen generator body, a fixed assembly on the fixed plate, and a moving mechanism including a bracket, a drive mechanism, a support plate, a rotating rod, a transmission mechanism, an inclined block, a fixed block, a screw, a universal joint, a threaded block, and a screw-slider block. A bracket is fixedly installed on the top wall of the inner cavity of the base box, and a drive mechanism is provided on the top of the inner side of the bracket.

[0004] During use, the device absorbs and mitigates impact forces by using a slider, a second spring, and a hinge rod to buffer and protect the nitrogen generator body. However, when the nitrogen generator is subjected to severe bumps or collisions, it usually generates a large displacement force. The buffer structure is unable to provide sufficient restraint to limit the displacement of the nitrogen generator, which can easily lead to loosening of the connection between the nitrogen generator and the fixed plate or other fixed parts, or even detachment. Utility Model Content

[0005] In view of the above-mentioned shortcomings of the existing technology, the present invention provides a nitrogen generator that is easy to transport, which can effectively solve the problem that the existing technology, which uses a slider, a second spring and a hinge rod to absorb and mitigate impact force, is unable to provide sufficient constraint force to limit the displacement of the nitrogen generator.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] This utility model provides a nitrogen generator that is easy to transport, including a base, multiple fixed frames fixedly connected to the inner wall of the base, a limiting rod slidably connected to the inner surface of the fixed frame, a movable wheel fixedly installed on the outer end face of the limiting rod, a fixed box fixedly installed on the top of the base, and a nitrogen generator set above the fixed box.

[0008] The auxiliary mechanism includes a telescopic assembly for simultaneously controlling the extension and retraction of multiple limit rods and moving wheels, a protective assembly for stably transmitting the rotational torque of the telescopic assembly, and a positioning assembly for limiting or releasing the nitrogen generator as the protective assembly rotates.

[0009] The telescopic component is located inside the base, the protective component is located above the telescopic component and can automatically cut off the transmission when the rotational torque is obstructed, and the positioning component is located inside the fixed box.

[0010] The telescopic assembly includes a motor adapted to be installed on the outer surface of the fixed frame, a first bevel gear fixedly connected to the output end of the motor via a coupling, a second bevel gear meshing with the outer surface of the first bevel gear, and a connecting column fixedly connected to the inner surface of the second bevel gear.

[0011] Furthermore, the telescopic assembly includes a worm gear fixedly installed at the through end of the connecting column, a worm wheel meshing with the two sides of the worm gear, a driven column fixedly connected to the inner surface of the worm wheel, a pressure rod fixedly sleeved on the outer end face of the driven column, and a force-bearing column fixedly connected to the inner surface of the limiting rod and used in conjunction with the pressure rod.

[0012] Furthermore, a rotating bearing sleeve is installed at the connection between the connecting column and the fixed frame, the driven column is rotatably connected to the inner surface of the fixed frame, and the inner surface of the pressure rod is in sliding contact with the outer surface of the force-bearing column.

[0013] When the motor drives the second bevel gear to rotate via the first bevel gear, the second bevel gear drives the connecting column and the worm to rotate synchronously. The worm then drives the worm wheels on both sides and the driven column to rotate synchronously. The driven column then drives the pressure rod to squeeze the force-bearing column, thereby causing the limiting rod to move vertically along the inner surface of the fixed frame.

[0014] Furthermore, the protective assembly includes a first helical gear disk slidably sleeved on the outer surface of the connecting column, a second helical gear disk meshing with the outer surface of the first helical gear disk, a transmission column fixedly connected to the outer end face of the second helical gear disk, and a spring sleeved on the outside of the connecting column and used in conjunction with the first helical gear disk.

[0015] Furthermore, the spring is fixedly installed on the outer surface of the connecting column, and its other end abuts against the bottom of the first helical gear plate; the transmission column is rotatably connected to the inner surface of the fixed box.

[0016] When the connecting column drives the first helical toothed disk to rotate, the first helical toothed disk can drive the second helical toothed disk and the transmission column to rotate synchronously through friction. When the rotation of the transmission column is blocked, the first helical toothed disk cannot drive the second helical toothed disk to continue rotating. At this time, the external structures of the first and second helical toothed disks squeeze each other, causing the first helical toothed disk to slide along the outer surface of the connecting column, compressing the spring, and cutting off the rotation transmission.

[0017] Furthermore, the positioning assembly includes a support plate fixedly sleeved on the through end of the transmission column, a movable rod hinged to both ends of the support plate, and a mounting plate hinged to the other end of the movable rod.

[0018] Furthermore, the positioning assembly also includes a fixing post fixedly connected to the top of the mounting plate, and a positioning block fixedly installed at the through end of the fixing post for fixing the nitrogen generator.

[0019] Furthermore, the fixing column is slidably connected to the inner surface of the fixing box;

[0020] When the transmission column drives the support plate to rotate, it can drive the mounting plate, fixed column and positioning block to move horizontally through the movable rod, thereby moving the positioning block closer to or further away from the nitrogen generator.

[0021] The technical solution provided by this utility model has the following advantages compared with the known prior art:

[0022] This utility model, by setting up an auxiliary mechanism, can not only control the extension of the moving wheels during the preparation for transporting the nitrogen generator, but also drive the positioning block to rigidly position the nitrogen generator, thus avoiding displacement of the nitrogen generator due to large displacement forces during transport. It can also automatically perform overload protection when the positioning block is in contact with the nitrogen generator, preventing damage to the nitrogen generator due to excessive clamping force. This ensures the stability of the nitrogen generator during transport while improving the smooth switching between moving and stationary states. Attached Figure Description

[0030] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the scope of protection of this utility model.

[0031] The present invention will be further described below with reference to the embodiments.

[0032] Example: A nitrogen generator that is easy to transport, see attached document. Figure 1 -Appendix Figure 5 ,include,

[0033] The base 110, multiple fixed brackets 120 fixedly connected to the inner wall of the base 110, a limiting rod 130 slidably connected to the inner surface of the fixed bracket 120, a moving wheel 140 fixedly installed on the outer end face of the limiting rod 130, a fixed box 150 fixedly installed on the top of the base 110, and a nitrogen generator 160 disposed above the fixed box 150.

[0034] It should be noted that the base 110 forms a layered structure with the lower moving wheels 140 and the upper nitrogen generator 160, so that the nitrogen generator body 100 can take into account both mobility and load-bearing capacity. The fixed frame 120 is used to provide a sliding track for the limiting rod 130. When the limiting rod 130 moves vertically along the inner surface of the fixed frame 120, it can drive the moving wheels 140 to move down to touch the ground or move up to lift off the ground, so as to facilitate the transportation or fixation of the nitrogen generator body 100. The fixed box 150 is used to support the nitrogen generator 160.

[0035] The auxiliary mechanism 200 includes a telescopic assembly 210 for simultaneously controlling the extension and retraction of multiple limit rods 130 and moving wheels 140, a protective assembly 220 for stably transmitting the rotational torque of the telescopic assembly 210, and a positioning assembly 230 for limiting or releasing the nitrogen generator 160 as the protective assembly 220 rotates.

[0036] The telescopic component 210 is located inside the base 110, the protective component 220 is located above the telescopic component 210 and can automatically cut off the transmission when the rotational torque is blocked, and the positioning component 230 is located inside the fixed box 150.

[0037] The telescopic assembly 210 includes a motor 211 adapted to be installed on the outer surface of the fixed frame 120, a first bevel gear 212 fixedly connected to the output end of the motor 211 via a coupling, a second bevel gear 213 meshing with the outer surface of the first bevel gear 212, and a connecting column 214 fixedly connected to the inner surface of the second bevel gear 213.

[0038] Specifically, the telescopic assembly 210 includes a worm 215 fixedly installed at the through end of the connecting column 214, a worm wheel 216 meshing with the two sides of the worm 215, a driven column 217 fixedly connected to the inner surface of the worm wheel 216, a pressure rod 218 fixedly sleeved on the outer end face of the driven column 217, and a force-bearing column 219 fixedly connected to the inner surface of the limiting rod 130 and used in conjunction with the pressure rod 218.

[0039] It should be noted that when the pressure rod 218 presses the force-bearing column 219, it can force the limiting rod 130 to move vertically along the inner surface of the fixed frame 120, so as to achieve the effect of controlling the moving wheel 140 to move down or retract up.

[0040] Furthermore, a rotating bearing sleeve is installed at the connection between the connecting column 214 and the fixed frame 120, the driven column 217 is rotatably connected to the inner surface of the fixed frame 120, and the inner surface of the pressure rod 218 slides in contact with the outer surface of the force-bearing column 219.

[0041] When the motor 211 drives the second bevel gear 213 to rotate via the first bevel gear 212, the second bevel gear 213 drives the connecting column 214 and the worm gear 215 to rotate synchronously. The worm gear 215 then drives the worm wheels 216 on both sides and the driven column 217 to rotate synchronously. The driven column 217 then drives the pressure rod 218 to squeeze the force-bearing column 219, thereby causing the limiting rod 130 to move vertically along the inner surface of the fixed frame 120.

[0042] Preferably, the protective assembly 220 includes a first helical gear 221 slidably sleeved on the outer surface of the connecting column 214, a second helical gear 222 meshing with the outer surface of the first helical gear 221, a transmission column 223 fixedly connected to the outer end face of the second helical gear 222, and a spring 224 sleeved on the outside of the connecting column 214 and used in conjunction with the first helical gear 221.

[0043] It should be noted that the spring 224 is fixedly installed on the outer surface of the connecting column 214, and its other end abuts against the bottom of the first helical gear plate 221. The transmission column 223 is rotatably connected to the inner surface of the fixed box 150.

[0044] When the connecting column 214 drives the first helical gear disk 221 to rotate, the first helical gear disk 221 can drive the second helical gear disk 222 and the transmission column 223 to rotate synchronously through friction. When the rotation of the transmission column 223 is blocked, the first helical gear disk 221 cannot drive the second helical gear disk 222 to continue rotating. At this time, the external structures of the first helical gear disk 221 and the second helical gear disk 222 squeeze each other, causing the first helical gear disk 221 to slide along the outer surface of the connecting column 214, compressing the spring 224, and cutting off the rotation transmission.

[0045] Furthermore, the positioning assembly 230 includes a support plate 231 fixedly sleeved on the through end of the transmission column 223, a movable rod 232 hinged to both ends of the support plate 231, and a mounting plate 233 hinged to the other end of the movable rod 232.

[0046] Specifically, the positioning component 230 also includes a fixing post 234 fixedly connected to the top of the mounting plate 233, and a positioning block 235 fixedly installed at the through end of the fixing post 234 for fixing the nitrogen generator 160.

[0047] It should also be noted that when the positioning block 235 is in contact with the nitrogen generator 160, the rotation of the transmission column 223 will be blocked. At this time, the second helical gear disk 222 cannot continue to rotate. Through the mutual squeezing force generated by its meshing surface with the first helical gear disk 221, the first helical gear disk 221 overcomes the elastic force of the spring 224, forcing the first helical gear disk 221 to slide down along the outer surface of the connecting column 214 and compress the spring 224. Finally, the first helical gear disk 221 and the second helical gear disk 222 disengage, cutting off the rotation transmission and preventing the positioning block 235 from continuously applying pressure and causing damage to the nitrogen generator 160.

[0048] Preferably, the fixing post 234 is slidably connected to the inner surface of the fixing box 150;

[0049] When the transmission column 223 drives the support plate 231 to rotate, it can drive the mounting plate 233, the fixed column 234 and the positioning block 235 to move horizontally through the movable rod 232, thereby moving the positioning block 235 closer to or further away from the nitrogen generator 160.

[0050] When using,

[0051] The starting motor 211 drives the first bevel gear 212 to rotate, and then the first bevel gear 212 drives the second bevel gear 213, the connecting column 214 and the worm gear 215 to rotate synchronously. The worm gear 215 then drives the worm wheels 216 on both sides and the driven column 217 to rotate, so that the driven column 217 drives the pressure rod 218 to rotate synchronously, and the pressure rod 218 squeezes the force-bearing column 219, thereby forcing the limiting rod 130 to move vertically downward along the inner surface of the fixed frame 120, so that the limiting rod 130 drives the moving wheel 140 to touch the ground.

[0052] When the connecting column 214 rotates, it can also drive the first helical gear disk 221 to rotate synchronously under the elastic force of the spring 224, which in turn drives the second helical gear disk 222, the transmission column 223 and the support plate 231. This causes the support plate 231 to pull the mounting plate 233 through the movable rod 232, and then, through the cooperation between the mounting plate 233 and the fixed column 234, drive the positioning block 235 to move horizontally closer to the nitrogen generator 160.

[0053] When the positioning block 235 is in contact with the nitrogen generator 160: the rotation of the transmission column 223 is obstructed. At this time, the first helical toothed disc 221 and the second helical toothed disc 222 squeeze each other, driving the first helical toothed disc 221 to overcome the elastic force of the spring 224 and slide down along the connecting column 214, cutting off the transmission and completing the positioning of the nitrogen generator 160. When it needs to be moved again, the motor 211 is started to move the positioning block 235 away from the nitrogen generator 160, so as to ensure that the positioning block 235 will not damage the nitrogen generator 160 when the moving wheel 140 extends to each length. At this time, the nitrogen generator body 100 can be pushed to move.

[0054] After being transported to the target location, the control motor 211 rotates in the opposite direction, driving the pressure rod 218 to move in the opposite direction, which in turn drives the moving wheel 140 to rise off the ground and drives the positioning block 235 away from the nitrogen generator 160.

[0055] In summary, by setting up the auxiliary mechanism 200, not only can the extension of the moving wheel 140 be controlled during the transportation preparation of the nitrogen generator 160, while driving the positioning block 235 to rigidly position the nitrogen generator 160, thus avoiding displacement of the nitrogen generator 160 due to large displacement forces during transportation, but also the positioning block 235 can automatically perform overload protection when it is in contact with the nitrogen generator 160, thus preventing damage to the nitrogen generator 160 due to excessive clamping force. This achieves the effect of ensuring the stability of the nitrogen generator 160 during transportation while improving the smooth switching between the moving and fixed states of the nitrogen generator 160.

[0056] The above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Such modifications or substitutions will not cause the essence of the corresponding technical solutions to deviate from the protection scope of the technical solutions of the embodiments of this utility model.
