Technical Field
[0001] This utility model relates to the technical field of nitrogen filling devices, and in particular to a rapid nitrogen filling device. Background Technology
[0002] A nitrogen filling device is a specialized piece of equipment for filling nitrogen springs with nitrogen. It typically consists of a nitrogen cylinder, a pressure reducing device, a filling valve, a pressure gauge, and connecting pipes. During operation, the pressure reducing device first reduces the high-pressure nitrogen in the nitrogen cylinder to a suitable range. Then, the filling valve slowly fills the nitrogen spring with nitrogen. During the filling process, the pressure gauge displays the filling pressure in real time, allowing operators to accurately control the amount of nitrogen added and ensure that the nitrogen spring reaches the specified working pressure, thus enabling it to perform its elastic function normally.
[0003] Existing technologies often have the following drawbacks: when using a nitrogen filling device to inflate a nitrogen spring, it often takes a long time to align the filling tube with the filling port on the nitrogen spring, thus reducing the inflation efficiency of the nitrogen spring.

[0017] The effect achieved by the above components is that the V-groove on the fixing plate can provide a certain degree of support and positioning for the air tank.

Detailed Implementation
[0028] Reference Figure 1As shown, this utility model provides a technical solution: a rapid nitrogen filling device, including a control console 1 and a nitrogen spring 7. One side of the control console 1 is connected to a storage tank 2 via a hose, and the other side of the control console 1 is connected to a filling tank 3 via a hose. A support platform 4 is fixedly connected to the side wall of the control console 1. The filling tank 3 is located above the support platform 4. A filling pipe 8 is fixedly installed on the upper side of the filling tank 3. A positioning structure 5 is provided on the surface of the support platform 4, and an installation structure 6 is provided on the upper surface of the support platform 4.
[0029] The specific settings and functions of its positioning structure 5 and installation structure 6 will be explained in detail below.
[0030] Reference Figures 1-3 As shown in this embodiment: the positioning structure 5 includes a sliding plate 501 slidably connected to the end of the support platform 4 away from the control console 1. Two limiting strips 502 are slidably connected inside the sliding plate 501. A support plate 504 is fixedly connected to the upper end of the two limiting strips 502. Connecting plates 505 are fixedly connected to both sides of the support plate 504. Positioning strips 506 are slidably connected inside the connecting plates 505. Positioning blocks 507 are fixedly connected to the ends of the two positioning strips 506 that are close to each other. Trapezoidal grooves 512 are provided on the sides of the two positioning blocks 507 that are close to each other. The nitrogen spring 7 is located between the two positioning blocks 507. By setting the positioning structure 5, the quick docking of the inflation port positions of the gas tank 3 and the nitrogen spring 7 is facilitated, and the rapid inflation of the nitrogen spring 7 is facilitated, further improving the inflation efficiency of the nitrogen filling device. The side of the positioning strip 506 away from the positioning block 507 is a bent structure. Simultaneously pressing the inclined surfaces of the two positioning strips 506 enables the simultaneous driving of the two positioning blocks 507 towards each other. A mounting plate 508 is fixedly connected to the side wall of the support plate 504. Two rectangular bars 510 are slidably connected inside the mounting plate 508, and U-shaped frames 509 with U-shaped structures are fixedly connected to the ends of the two rectangular bars 510. The U-shaped frames 509 slide within the mounting plate 508 via the rectangular bars 510, simultaneously pressing against the inclined surfaces of the two positioning bars 506. A second drive rod 511 is threadedly connected inside the mounting plate 508, and the second drive rod 511 is rotatably connected to the inside of the U-shaped frame 509. Rotating the second drive rod 511 allows the U-shaped frame 509 to slide within the mounting plate 508 via the rectangular bars 510. A first drive rod 503 is threadedly connected inside the sliding plate 501, and the first drive rod 503 is rotatably connected to the inside of the support plate 504. When the first drive rod 503 rotates, the sliding plate 501 slides on the support platform 4, thereby moving the support plate 504, connecting plate 505, positioning bars 506, and positioning blocks 507.
[0031] Reference Figures 1-2 and Figure 4As shown, specifically, the installation structure 6 includes a fixing plate 61 fixedly connected to the upper surface of the support platform 4, and a V-groove 62 is formed on the surface of the fixing plate 61. The V-groove 62 on the fixing plate 61 can provide a certain degree of support and positioning for the inflation tank 3. A rectangular block 63 is fixedly connected to the upper surface of the support platform 4. Two pressure frames 64 are slidably connected inside the rectangular block 63. The pressure frames 64 have a U-shaped structure. An anti-slip pad 66 is glued to the side of the pressure frame 64 near the inflation tank 3. A screw 65 is threadedly connected inside the rectangular block 63. The screw 65 is rotatably connected to the inside of the pressure frame 64. Rotating the screw 65 can drive the pressure frame 64 to slide inside the rectangular block 63. The anti-slip pad 66 on one side of the pressure frame 64 can press the inflation tank 3 tightly, further enhancing the stability of the inflation tank 3, ensuring smooth inflation, and effectively improving the inflation efficiency of the nitrogen spring 7.
[0032] Working principle: When using this rapid nitrogen filling device, firstly, the nitrogen spring 7 is placed on the support plate 504. Rotating the first drive rod 503 causes the slide plate 501 to slide on the support platform 4. Since the slide plate 501 is internally threaded to the first drive rod 503, and the first drive rod 503 is rotatably connected to the support plate 504, rotating the first drive rod 503 causes the slide plate 501 to move, thereby moving the support plate 504, connecting plate 505, positioning strip 506, and positioning block 507. When the nitrogen spring 7 is positioned between the two positioning blocks 507, the trapezoidal groove 512 on the positioning block 507 can adapt to the shape of the nitrogen spring 7, providing initial positioning. The two positioning blocks 507 can be adjusted according to the size of the nitrogen spring 7, improving the applicability of the device. Rotating the second drive rod 511, which is threaded to the mounting plate 508 and rotatably connected to the U-shaped frame 509, further facilitates the movement of the nitrogen spring 7. The second drive rod 511 allows the U-shaped frame 509 to slide within the mounting plate 508 via the rectangular strip 510, simultaneously pressing the inclined surfaces of the two positioning strips 506. This enables the two positioning blocks 507 to move closer to each other simultaneously, thus achieving more precise positioning of the nitrogen spring 7. The operator only needs to rotate the nitrogen spring 7 between the two positioning blocks 507 to accurately align its inflation port with the inflation tube 8. After positioning, sliding the slide plate 501 allows for docking between the inflation tank 3 and the nitrogen spring 7. Opening the control panel 1 allows nitrogen from the storage tank 2 to enter the inflation tank 3 after adjustment by the control panel 1, and then inflate the nitrogen spring 7 through the inflation tube 8. By setting the positioning structure 5, the rapid docking of the inflation ports of the inflation tank 3 and the nitrogen spring 7 is facilitated, making it easier to quickly inflate the nitrogen spring 7 and further improving the inflation efficiency of the nitrogen filling device.
[0033] The mounting structure 6 set on the support platform 4 also plays a role. The V-groove 62 on the fixing plate 61 can provide a certain support and positioning for the inflation tank 3, preventing the inflation tank 3 from shaking. At the same time, rotating the screw 65 can drive the pressure frame 64 to slide within the rectangular block 63. The anti-slip pad 66 on one side of the pressure frame 64 can press the inflation tank 3 tightly, further enhancing the stability of the inflation tank 3 and ensuring that the inflation process is smooth. This effectively improves the inflation efficiency of the nitrogen spring 7. By setting the mounting structure 6, it is convenient to flexibly fix the inflation tank 3 according to the usage requirements, further improving the performance of the nitrogen filling device.
