Description

Technical Field

[0001] The utility model relates to an ultra-long clean stainless steel seamless pipe. Background Art

[0002] Extra-long clean stainless steel seamless pipes are often used to transport media. Due to the extra-long length of this steel pipe, the middle part will inevitably sag. Once the medium in the pipe body produces turbulence and water hammer, the pipe body will also vibrate or jump, which will cause a violent collision between the pipe body and the ground, which is very likely to cause damage to the pipe body;

[0003] In order to avoid the above situation, a bracket is generally set between the ground and the pipe body. However, when the corresponding pipe body vibrates or jumps, the impact force will be transmitted to the bracket, which may cause severe friction or collision between the pipe body and the bracket, and may also cause the bracket fixed to the ground to loosen, and then the pipe body will hit the ground with the bracket, and it is still difficult to avoid damage to the pipe body. In addition, the assembly of such a bracket and the pipe body is also relatively complicated, and it is inconvenient to install and disassemble. Utility Model Content

[0004] The utility model aims to overcome the deficiencies of the above-mentioned prior art and to provide an ultra-long clean stainless steel seamless pipe, which is equipped with a more reliable support seat to prevent the pipe body from being damaged due to turbulence or water hammer and severe impact with the ground, and the support seat and the pipe body are more convenient to disassemble and assemble.

[0005] The technical solution of the utility model is: an ultra-long clean stainless steel seamless pipe, comprising a pipe body and a support seat arranged on the pipe body at equal distances, wherein the support seat is composed of a left body and a right body;

[0006] The left body comprises an upper body and a lower body rotatably connected to the bottom of the upper body, the inner sides of the upper body and the lower body respectively have arc-shaped surfaces corresponding to the outer surface of the tube body, the inner side of the upper body also has a slot, the inner side of the slot has a limit groove, the limit groove has a through hole that passes through the outer side of the upper body, a rod body is telescopically connected in the through hole, and the outer end of the rod body has a button;

[0007] The structure of the right body is the same as that of the upper body;

[0008] The two sides of the tube body are respectively provided with a limiting boss, the outer side of the limiting boss is telescopically connected with a limiting block, the limiting boss is inserted into the corresponding slot of the upper body, the limiting block is stuck in the limiting groove, and the arc surface of the lower end of the upper body is in contact with one side of the lower end of the tube body;

[0009] The lower bodies of the left body and the right body are spaced apart and connected by elastic ropes. When the tube body does not vibrate violently, the arc surfaces of the lower bodies of the left body and the right body are respectively in contact with the two side surfaces of the lower end of the tube body.

[0010] Further, a clamping groove is respectively provided on the front and rear sides of the slot, and a clamping bar is respectively provided on the front and rear sides of the limiting boss.

[0011] Further, a first spring is provided in the through hole, a spring seat corresponding thereto is provided on the rod body, a limiting hole corresponding to the first spring is further provided in the through hole, the first spring is sleeved on the rod body and its two ends respectively abut against the spring seat and the outer end of the limiting hole.

Aligning the support seat with the limiting boss on the pipe body and clamping it in can complete the combination. Pressing the button to make the rod body press the limiting block to retract can pull out the support seat from the pipe body; In the normal state of the pipe body, the lower bodies of the left body and the right body are arranged close to both sides of the lower end of the pipe body under the action of the elastic cable and cooperate with the two upper bodies to support the pipe body; When turbulence or water hammer occurs in the pipe body, the pipe body generates violent跳动.

DETAILED DESCRIPTION

[0023] The technical solution of the utility model is further specifically described below through embodiments and in conjunction with the accompanying drawings.

[0024] Combination Figure 1-3 As shown, an ultra-long clean stainless steel seamless pipe comprises a pipe body 1 and a support seat equidistantly arranged on the pipe body 1, wherein the support seat consists of a left body and a right body;

[0025] The left body comprises an upper body 2 and a lower body 3 rotatably connected to the bottom of the upper body 2. The inner sides of the upper body 2 and the lower body 3 respectively have arc-shaped surfaces corresponding to the outer surface of the tube body 1. The inner side of the upper body 2 also has a slot 4. The inner side of the slot 4 has a limit groove 5. The limit groove 5 has a through hole 6 that passes through the outer side of the upper body 2. A rod body 7 is telescopically connected in the through hole 6. The outer end of the rod body 7 has a button 8.

[0026] The structure of the right body is the same as that of the upper body 2;

[0027] The tube body 1 is provided with a limiting boss 9 on both sides, and a limiting block 10 is telescopically connected to the outer side of the limiting boss 9. The limiting boss 9 is inserted into the corresponding slot 4 of the upper body 2, and the limiting block 10 is inserted into the limiting groove 5. The arc surface of the lower end of the upper body 2 is in contact with one side of the lower end of the tube body 1.

[0028] The lower bodies 3 of the left and right bodies are spaced apart and connected by elastic ropes 11 . When the tube body 1 does not vibrate violently, the arc surfaces of the lower bodies 3 of the left and right bodies abut against the two side surfaces of the lower end of the tube body 1 .

[0029] In the above structure, the combination and separation of the pipe body 1 and the support are simple and convenient. The combination is completed by aligning the support with the limit boss 9 on the pipe body 1 and snapping it in.

Under normal conditions of the pipe body 1, the lower bodies 3 of the left body and the right body are arranged close to both sides of the lower end of the pipe body 1 under the action of the elastic cable 11, and cooperate with the two upper bodies 2 to support the pipe body 1. When turbulence or water hammer occurs inside the pipe body 1, the pipe body 1 generates violent跳动. At this time, the two lower bodies 3 of the left body and the right body turn outwards by a corresponding amplitude under the action of the impact force to play a role in unloading force. After the impact force disappears, the two lower bodies 3 reset under the action of the elastic cable 11, and the two upper bodies 2 always keep supporting the pipe body 1, which can avoid violent collisions between the pipe body 1 and the support with the ground and between the pipe body 1 and the support, thereby ensuring the reliability of the pipe body 1.

The clamping strip 13 cooperates with the corresponding clamping groove 12 to limit the front and rear ends of the left body or the right body.

[0031] In another embodiment, in combination Figure 1 and Figure 3 as shown, a first spring 14 is arranged in the through hole 6, a corresponding spring seat 15 is provided on the rod body 7, a limit hole 16 corresponding to the first spring 14 is also provided in the through hole 6, and the first spring 14 is sleeved inside the rod body 7 and its two ends respectively abut against the spring seat 15 and the outer end of the limit hole 16.

[0032] In another embodiment, as Figure 3 shown, a cover plate 17 is fixed outside the through hole 6, and the cover plate 17 is provided with a connection hole corresponding to the rod body 7 to facilitate the assembly of the rod body 7 and the spring.

[0033] In another embodiment, as Figure 3 shown, the limit block 10 is in the shape of a right trapezoid, the inclined surface of the limit block 10 is downward, and the limit block 10 is connected to the limit boss 9 through spring expansion and contraction to facilitate the limit block 10 to be snapped into the corresponding limit groove 5.

[0034] In another embodiment, as Figure 3 shown, the rod body 7 is arranged corresponding to the upper end of the limit block 10.

[0035] In another embodiment, as Figure 1 shown, the bottom of the lower body 3 is further provided with a "factory"-shaped avoidance groove 18 to enable the lower body 3 to better turn outwards for unloading force.

[0036] In another embodiment, as Figure 1As shown, a first elastic cushion layer 19 is also provided at the bottom of the lower body 3 to play a buffering role.

[0037] In another embodiment, if Figure 1 As shown, a second elastic cushion layer 20 is also provided on the arc surface of the lower body 3 to prevent the lower body 3 from violently hitting the outer surface of the tube body 1 when it is reset after unloading the force.
