Description

Technical Field

[0001] This utility model relates to the field of work technology, and in particular to a nitrogen cylinder rotation limiting device. Background Technology

[0002] Nitrogen cylinders are widely used as important containers for storing and transporting nitrogen in many fields such as industrial production, laboratory research and medicine. Because nitrogen cylinders store high-pressure gas, rotation limit devices are usually used to fix them during placement, handling and use to prevent gas leakage, explosion and other safety accidents caused by the nitrogen cylinder tipping over or rolling.

[0003] Most nitrogen cylinder rotation limiting devices on the market currently adopt a fixed structure design. The clamping parts of these limiting devices have a fixed height and can only be adapted to nitrogen cylinders of a specific height. When faced with nitrogen cylinders of different heights, the upper clamping block cannot be lowered to a suitable position, and the top of the nitrogen cylinder cannot be effectively limited. This makes the cylinder prone to rotation or even tipping over when subjected to external forces (such as shaking during transportation or slight collisions). At the same time, because the existing limiting devices cannot flexibly adapt to nitrogen cylinders of different heights, in actual use, operators may adopt some non-standard fixing methods to make do with the use, further reducing the safety of nitrogen cylinder use. Utility Model Content

[0004] The purpose of this utility model is to at least solve one of the technical problems existing in the prior art, and to provide a nitrogen cylinder rotation limiting device. This device can solve the problem that the clamping part of the limiting device is fixed in height and can only be adapted to nitrogen cylinders of a specific height. When faced with nitrogen cylinders of different heights, the upper clamping block cannot be lowered to a suitable position, and the top of the nitrogen cylinder cannot be effectively limited. This causes the cylinder to easily rotate or even tip over when subjected to external forces (such as shaking during transportation, slight collisions, etc.). At the same time, since the existing limiting device cannot flexibly adapt to nitrogen cylinders of different heights, in actual use, operators may adopt some non-standard fixing methods to make do with it, which further reduces the safety of nitrogen cylinder use.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a nitrogen cylinder rotation limiting device, comprising a mounting base and two lower clamping blocks, wherein the mounting base is provided with two adjusting devices;

[0006] The adjustment device includes a sliding block, a movable seat, an upper clamping block, and two support rods.

The outer walls of the two support rods away from the upper clamping block are provided with multiple first fixing bolt slots. The outer walls of the movable seat away from the upper clamping block are threaded with two first fixing bolts. The two adjustment devices are used in conjunction.

[0008] Preferably, the outer walls of the two support rods are slidably connected to the interior of the corresponding support rod groove, and the outer walls of the two protruding plates at the rear end of the upper clamping block are slidably connected to the interior of the corresponding groove.

[0009] Among them, the ends of the four second fixing bolts near the second fixing bolt grooves are all threaded into the inside of the grooves and respectively connected to the internal threads of the corresponding second fixing bolt grooves.

[0016] Preferably, the lower end of the sliding block is threadedly connected to the outer wall of the corresponding threaded rod;

[0030] Please see Figure 1-4 This utility model provides a technical solution: a nitrogen cylinder rotation limiting device, including a mounting base 1 and two lower clamping blocks 10;

[0031] The mounting base 1 is equipped with two adjustment devices;

[0032] The adjusting device includes a sliding block 2, a movable seat 4, an upper clamping block 5, and two support rods 3. Both support rods 3 are fixedly connected to the upper surface of the sliding block 2. The movable seat 4 has two support rod grooves 12, and the outer walls of the two support rods 3 are slidably connected to the interior of their respective support rod grooves 12. One outer wall of the movable seat 4 has a positioning groove 17, and the rear outer wall of the upper clamping block 5 is slidably connected to the interior of the positioning groove 17. Both outer walls of the movable seat 4 have grooves 16, and the outer walls of the two convex plates at the rear end of the upper clamping block 5 are slidably connected to the interior of their respective grooves 16. Each of the two grooves 16 has two second fixing bolt grooves 15. The outer walls of the two convex plates at the rear end of the upper clamping block 5 are slidably connected to the interior of their respective grooves 16. Each of the four second fixing bolts 8 is threadedly connected to the upper clamping block 5. The ends of the four second fixing bolts 8 near the second fixing bolt groove 15 are threaded into the interior of the groove 16 and respectively connected to the internal threads of the corresponding second fixing bolt groove 15. The front end of the upper clamping block 5 is arc-shaped. The outer wall of the two support rods 3 away from the upper clamping block 5 is provided with multiple first fixing bolt grooves 6. The outer wall of the moving seat 4 away from the upper clamping block 5 is threadedly connected to the upper clamping block 5 with two first fixing bolts 7. The ends of the two first fixing bolts 7 near the first fixing bolt groove 6 are threaded into the interior of the support rod groove 12 and respectively connected to the internal threads of the corresponding first fixing bolt groove 6. The two adjusting devices are used in conjunction.

[0033] The mounting base 1 has a fixed plate 9 on its upper surface. Cylinders 11 are installed on the outer walls of the two protruding plates on both sides of the mounting base 9. The output ends of the two cylinders 11 slide to the outside of the protruding plates and are fixedly connected to the outer walls of the corresponding lower clamping blocks 10. A dual-axis motor 14 is installed inside a groove on the upper surface of the mounting base 1. Threaded rods 13 are fixedly connected to the output ends of the dual-axis motor 14. The ends of the two threaded rods 13 away from the dual-axis motor 14 are rotatably connected to the inner walls of the groove on both sides of the upper surface of the mounting base 1. The lower ends of the two sliding blocks 2 are threadedly connected to the outer walls of the corresponding threaded rods 13. The outer walls of the tapered blocks at the lower ends of the two sliding blocks 2 are slidably connected to the inner walls of the tapered grooves on both sides of the mounting base 1.

[0034] Furthermore, when using this device, it is started by connecting to an external power source. First, the device is installed in the designated position via the mounting base 1. When it is necessary to limit and fix the nitrogen cylinder, the nitrogen cylinder is first placed on the placement plate 9, and the dual-axis motor 14 is started. The output ends of the dual-axis motor 14 drive the threaded rod 13 to rotate. Since the lower end of the sliding block 2 is threadedly connected to the threaded rod 13, and the tapered blocks on both sides of the lower end slide in engagement with the tapered grooves of the mounting base 1, the sliding block 2 will move horizontally along the track on the mounting base 1 under the drive of the threaded rod 13, causing the two adjusting devices to move closer to each other. Meanwhile, as the adjusting device approaches the nitrogen cylinder, depending on the size of the nitrogen cylinder, the first fixing bolt 7 can be loosened first, and the height of the moving seat 4 on the support rod 3 can be adjusted so that the upper clamping block 5 matches the height of the nitrogen cylinder. After adjustment, the first fixing bolt 7 is tightened to fix the position of the moving seat 4 and the upper clamping block 5. At the same time, the output end of the cylinder 11 extends and drives the lower clamping block 10 to move towards each other. At this time, the upper clamping block 5 and the lower clamping block 10 of the two adjusting devices cooperate to clamp the nitrogen cylinder from both the top and bottom, so that the nitrogen cylinder is firmly fixed in the device, thereby realizing the rotation limit of the nitrogen cylinder.

[0035] By adjusting the device according to the size of the nitrogen cylinder, the first fixing bolt 7 can be loosened first, and the height of the moving seat 4 on the support rod 3 can be adjusted so that the upper clamping block 5 is adapted to the height of the nitrogen cylinder. After the adjustment is completed, the first fixing bolt 7 is tightened to fix the position of the moving seat 4 and the upper clamping block 5. This can clamp and fix nitrogen cylinders of different heights, effectively improving the practicality and flexibility of the device, while also improving the safety of nitrogen cylinder use.

[0036] Structural Description: Mounting Base 1: As the basic component of the entire device, it serves as the carrier for mounting other components. Its upper surface is used to mount and place components such as plate 9 and dual-axis motor 14. The tapered grooves on both sides provide sliding guidance for sliding block 2, ensuring the stability and accuracy of sliding block 2 during movement.

[0037] Sliding block 2: The lower end is threadedly connected to the threaded rod 13, and the tapered blocks on both sides of the lower end slide in fit with the tapered groove of the mounting base 1. Driven by the threaded rod 13, the sliding block 2 can move horizontally along a specific track on the mounting base 1, thereby driving other components connected to it to move synchronously.

[0038] Support rod 3: It is fixedly connected to the upper surface of the sliding block 2, and plays a supporting and guiding role. Its outer wall is slidably connected to the support rod groove 12 on the movable seat 4, so that the movable seat 4 can move up and down along the direction of the support rod 3. At the same time, the multiple first fixing bolt grooves 6 opened on the support rod 3 are used to cooperate with the first fixing bolts 7 to fix the position of the movable seat 4.

[0039] The movable seat 4 is a key component connecting the upper and lower clamping blocks. It is slidably connected to the support rod 3 through the support rod groove 12 and can be adjusted in the vertical direction. The positioning groove 17 on one side and the grooves 16 on both sides cooperate with the upper clamping block 5 to provide sliding space for the upper clamping block 5. The second fixing bolt groove 15 in the groove 16 cooperates with the second fixing bolt 8 to fix the upper clamping block 5.

[0040] Upper clamping block 5: The rear end is slidably connected to the positioning groove 17 and groove 16 of the movable seat 4, and is fixed to the movable seat 4 by the second fixing bolt 8. The front end is arc-shaped. This design can better fit the outer surface of the nitrogen cylinder, thereby achieving clamping and fixing of the nitrogen cylinder.

[0041] First fixing bolt 7 and first fixing bolt groove 6: The first fixing bolt 7 is threadedly connected to the movable seat 4. When it is necessary to adjust the height of the movable seat 4 on the support rod 3, the first fixing bolt 7 is loosened and the movable seat 4 can slide along the support rod 3. After adjusting to the appropriate position, the first fixing bolt 7 is tightened so that it is threadedly connected to the first fixing bolt groove 6, and the movable seat 4 is fixed at the corresponding height.

[0042] Second fixing bolt 8 and second fixing bolt groove 15: The second fixing bolt 8 is threadedly connected to the two protruding plates on the rear end of the upper clamping block 5. When the second fixing bolt 8 is loosened, the upper clamping block 5 can slide in the positioning groove 17 and groove 16 of the movable seat 4. After adjusting to the appropriate position, tighten the second fixing bolt 8 so that it is threadedly connected to the second fixing bolt groove 15 to fix the upper clamping block 5.

[0043] Lower clamping block 10: works in conjunction with upper clamping block 5 to clamp and fix the nitrogen cylinder, ensuring the stability of the nitrogen cylinder in the device;

[0044] Placement plate 9: Fixed on the upper surface of mounting base 1, used to place nitrogen cylinder, providing a stable support plane for nitrogen cylinder; the two protruding plates on both sides of placement plate 9 are used to install cylinder 11.

[0045] Cylinder 11: Installed on the two convex plates on both sides of the placement plate 9, its output end can slide to the outside of the convex plate. The function of cylinder 11 is to drive the lower clamping block 10 to cooperate with the upper clamping block 5 to clamp, further ensuring the fixation effect of the nitrogen cylinder.

[0046] Dual-axis motor 14: Installed in the groove opened on the upper surface of the mounting base 1, with its two output ends connected to the threaded rod 13 respectively. The dual-axis motor 14 provides power to the entire device and drives the threaded rod 13 to rotate, thereby realizing the horizontal movement of the sliding block 2.

[0047] Threaded rod 13: Both ends are rotatably connected to the output end of the dual-axis motor 14 and the inner walls of the slots on the upper surface of the mounting base 1, respectively. The outer wall is threadedly connected to the lower end of the sliding block 2. Under the drive of the dual-axis motor 14, the rotation of the threaded rod 13 is converted into the horizontal linear motion of the sliding block 2.

[0048] Positioning groove 17, groove 16 and support rod groove 12: Positioning groove 17 is used to position and guide the upper clamping block 5, groove 16 provides sliding space for the upper clamping block 5 and cooperates with the second fixing bolt groove 15 to fix the upper clamping block 5, and support rod groove 12 provides sliding space for the support rod 3 and cooperates with the first fixing bolt groove 6 to realize the height adjustment of the moving seat 4.

[0049] The embodiments of the present utility model have been described in detail above with reference to the accompanying drawings. However, the present utility model is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present utility model.
