Description

Technical Field

[0001] This utility model relates to the field of pipe clamping technology, specifically to a clamping structure for an oxygen delivery pipe. Background Technology

[0002] In practice, gas transportation is mostly carried out through pipelines. Due to the different properties of different gases, the requirements for the transportation pipelines are also different. Existing oxygen transportation methods include cylinder transportation and pipeline transportation. Pipeline transportation requires the use of pipes, and at the pipe joints, clamping structures are needed for connection and fixation.

[0003] Chinese utility model patent CN222502959U discloses an oxygen delivery pipe clamping structure. This device drives two moving plates to move simultaneously by rotating a bidirectional screw, and uses arc-shaped clamping blocks to hold the oxygen pipe, achieving a certain level of work efficiency. However, when the device is used for a long time, the arc-shaped clamping blocks deform under external force or the two wear to different degrees. After one arc-shaped clamping block clamps the oxygen pipe, there is a certain gap between the other arc-shaped clamping block and the oxygen pipe, and it is not clamped on one side of the oxygen pipe. At this time, the device needs to be repaired. However, the device does not have a mechanism to adjust the distance between the two arc-shaped clamping blocks in order to clamp the oxygen pipe simultaneously, so its practicality is not very good. Utility Model Content

[0004] (a) Technical problems to be solved

[0005] To address the shortcomings of existing technologies, this utility model provides an oxygen delivery pipeline clamping structure, which improves practicality.

[0006] (II) Technical Solution

[0007] To achieve the above objectives, this utility model provides the following technical solution: an oxygen delivery pipe clamping structure, comprising a shell, an oxygen delivery pipe, and a bidirectional threaded rod. Two threaded tubes are connected to the bidirectional threaded rod by reverse threads. A fixing pipe is sleeved onto the outer tubes of both threaded tubes. The fixing pipe has an internal cavity extending through both its upper and lower ends. The inner wall of the cavity is flush with the outer tube of the threaded tube. A through hole is formed in the side wall of the fixing pipe, with one end of the through hole penetrating the cavity of the fixing pipe. A compression fixing rod is connected through the through hole. In use, the compression fixing rod moves within the through hole, approaching the threaded tube and ultimately compressing it. A lifting plate is fixedly installed on the outside of the fixing pipe. A clamping assembly is provided on one side of the lifting plate for clamping and fixing the oxygen delivery pipe. The fixing pipe slides on the threaded tube, adjusting the position of the clamping assembly.

[0008] Furthermore, the compression fixing rod is a screw rod, and the screw rod has external threads on its outside, with the inner wall of the through hole fitting against the external threads.

[0009] Furthermore, a fixing plate is fixedly installed at the end of the screw away from the fixing tube, and a slot is opened on the fixing plate.

[0010] Furthermore, a support plate is fixedly installed on the lifting plate, and a threaded hole is opened on the support plate. The inner wall of the threaded hole is provided with an internal thread, which matches the external thread of the screw.

[0011] Preferably, the clamping assembly includes a clamping plate, and a sealing gasket is fixedly provided at one end of the clamping plate near the oxygen delivery tube.

[0012] Preferably, a turntable is fixedly provided on the top of the bidirectional threaded rod, and anti-slip stripes are provided on the outer wall of the turntable.

[0013] (III) Beneficial Effects

[0014] Compared with the prior art, this utility model provides an oxygen delivery pipeline clamping structure, which has the following characteristics:

[0015] Beneficial effects:

[0016] This oxygen delivery pipe clamping structure allows for different distances between the upper and lower clamping plates and the oxygen delivery pipe. By rotating the bidirectional threaded rod, the clamping plates are brought closer to the oxygen delivery pipe. When one clamping plate is clamped on one side of the oxygen delivery pipe, simply rotating the screw stops it from pressing against the threaded pipe. As the bidirectional threaded rod rotates, it stops moving the clamping plate, while the other clamping plate continues to move towards the oxygen delivery pipe. This allows the upper and lower clamping plates to clamp the oxygen delivery pipe again without needing to align their positions, thus improving practicality. Attached Figure Description

[0023] 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.

[0024] Please see Figure 1-5 This utility model discloses an oxygen delivery pipe clamping structure, comprising a housing 1, an oxygen delivery pipe 2, and a bidirectional threaded rod 3. A turntable 13 is fixedly mounted on the top of the bidirectional threaded rod 3. The outer wall of the turntable 13 is provided with anti-slip stripes. When the operator grasps the anti-slip stripes on the outside of the turntable 13 and rotates it, the bidirectional threaded rod 3 can be rotated on the housing 1. Two threaded tubes 4 are connected to the bidirectional threaded rod 3 by reverse threads. When the bidirectional threaded rod 3 rotates, it rotates relative to the threaded tubes 4. A fixing tube 5 is sleeved on the outer tube of each of the two threaded tubes 4. The fixing tube 5 has a cavity inside, extending through both the upper and lower ends. The inner wall of the cavity is fitted together with the outer tube of the threaded tube 4. A through hole 6 is opened through the side wall of the fixing tube 5. One end of the through hole 6 penetrates the cavity of the fixing tube 5. A compression fixing rod is connected through the through hole 6. In use... The compression fixing rod moves within the through hole 6, approaches the threaded tube 4, and finally compresses the threaded tube 4, fixing the fixing tube 5 and the threaded tube 4 together. A lifting plate 7 is fixedly installed on the outside of the fixing tube 5. The lifting plate 7 can restrict the fixing tube 5 and prevent it from rotating, so that the threaded tube 4, which is fixed by the compression fixing rod, no longer rotates when the bidirectional threaded rod 3 rotates. Instead, the threaded tube 4 moves up and down along the axis of the bidirectional threaded rod 3. A clamping component is provided on one side of the lifting plate 7 to clamp and fix the oxygen delivery tube 2. After fixing the oxygen delivery tube 2, one end of the compression fixing rod no longer compresses and fixes the threaded tube 4. At this time, the fixing tube 5 is no longer fixed to the threaded tube 4. The fixing tube 5 slides on the threaded tube 4. Adjust the position of the clamping component so that the clamping components at both ends are clamped on the oxygen delivery tube 2.

[0025] The compression fixing rod is a screw 8, which has an external thread. The inner wall of the through hole 6 is fitted to the external thread. A fixing plate 9 is fixedly installed at the end of the screw 8 away from the fixing tube 5. The fixing plate 9 has a slot. The operator inserts the end of a screwdriver into the slot and then rotates the screwdriver, which drives the fixing plate 9 to rotate, thereby driving the screw 8 to rotate. A support plate 10 is fixedly installed on the lifting plate 7. The support plate 10 has a threaded hole. The inner wall of the threaded hole has an internal thread that matches the external thread of the screw 8. When the screw 8 is rotated, the screw 8 rotates in the threaded hole of the support plate 10.

[0026] The clamping assembly includes a clamping plate 11 for clamping and fixing the oxygen delivery tube 2. A sealing gasket 12 is fixedly provided at one end of the clamping plate 11 near the oxygen delivery tube 2. The sealing gasket 12 is attached to the outer wall of the oxygen delivery tube 2 to improve the sealing performance.

[0027] In summary, this oxygen delivery pipe clamping structure, when the distances of the clamping plates 11 in the vertical direction from the oxygen delivery pipe 2 are different, can grip and rotate the turntable 13, causing the bidirectional threaded rod 3 to rotate. This causes the threaded pipe 4, the fixed pipe 5, and the lifting plate 7 to move closer to each other, and the clamping plates 11 to move closer to the oxygen delivery pipe 2. When the sealing gasket 12 at one end of one of the clamping plates 11 is in contact with the outer wall of the oxygen delivery pipe 2, the screw 8 on the lifting plate 7 is rotated so that one end of the screw 8 no longer abuts against the threaded pipe 4. Then the bidirectional threaded rod 13 is rotated. The threaded rod 3 drives the threaded tube 4 to rotate. The threaded tube 4 rotates inside the fixed tube 5, while the clamping plate 11 on one side of the other lifting plate 7 continues to move closer to the oxygen delivery tube 2 until the sealing gasket 12 at one end of the clamping plate 11 is attached to the outer wall of the oxygen delivery tube 2. Then, the previously adjusted screw 8 is rotated so that the screw 8 enters the through hole 6 of the fixed tube 5 and finally tightly abuts against the threaded tube 4, fixing the fixed tube 5 and the threaded tube 4 together. At this time, the clamping plates 11 at both ends hold the oxygen delivery tube 2, and it can continue to be used.

[0028] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
