Description

Technical Field

[0001] The utility model relates to the technical field of pipe head protection, in particular to a pipe head protection structure for a thermal insulation pipe. Background Art

[0002] In a pipeline system, the pipe head usually refers to the part that is directly connected to the pump or pipeline system. By connecting the pipe head, good sealing and stability can be ensured to avoid fluid leakage and pipeline falling off. Usually, the pipe head protection structure for insulated pipes is a common structure during transportation, which can prevent the pipe head from being damaged by the transportation environment.

[0003] According to the Chinese patent publication number CN221569850U "A pipe head protection structure for insulation pipes", it mainly describes that an inflated elastic corrugated airbag is set as an elastic structure, so that when the sleeve tube collides with the ground or other objects, the inflated elastic corrugated airbag structurally eliminates the hidden danger of the insulation pipe head being damaged due to the impact of the sleeve tube, and the sleeve tube set on the pipe head of the insulation pipe also solves the problem of the staff accidentally bumping into the pipe head and causing scratches on the body, and the pear-shaped rubber sleeve set at the tail of the sleeve tube can improve the impact resistance of the sleeve tube, and the arc-shaped rubber ridges on the pear-shaped rubber sleeve are deformed after contacting the ground, which further protects the pipe head of the insulation pipe. When transporting the pipe head, the airbag is used to limit the pipe head, but the airbag will gradually deflate under time and pressure conditions, resulting in a worse protection effect of the elbow.

[0004] Therefore, a pipe head protection structure for an insulated pipe is proposed to solve the problem of using an airbag to limit the pipe head during transportation. However, the airbag will gradually deflate under time and pressure conditions, resulting in a deterioration in the protection effect of the elbow. Utility Model Content

[0005] The technical problem to be solved by the present invention is: when transporting the pipe head, an air bag is used to limit the pipe head. However, the air bag will gradually deflate under time and pressure conditions, resulting in a problem that the protective effect of the elbow becomes worse. Therefore, a pipe head protection structure for an insulation pipe is proposed.

[0006] The cam is fixedly provided with a protective sleeve and a locking plate, and the locking plate is fixedly secured to the bottom of the protective sleeve and is secured to a central position within the protective sleeve.

[0007] As a preferred technical solution of the present invention, the limiting airbags are located on four sides away from each other in the protective tube, and contact strips are evenly and fixedly connected to the limiting airbags. The contact strips are made of rubber material. By setting four limiting airbags in conjunction with the contact strips, the friction between the elbow and the airbags can be reduced when the elbow is limited.

[0008] As an optimal technical solution of the present invention, a gasket is glued to the bottom side of the protective tube, and four sides of the gasket that are far away from each other are fixedly connected to rubber protrusions. By arranging the gasket and rubber protrusions, the friction caused by the elbow directly colliding with the protective tube can be reduced.

[0009] As a preferred technical solution of the present invention, grooves are provided on the four sides of the pressure ring that are away from each other, and a pressure rod is rotatably connected to the groove through a third rotating shaft. By setting the pressure rod, the gas can be repeatedly pressed to pass through the first through hole and the first rotating plate into the limiting airbag and replenish the air.

[0010] As an optimal technical solution of the present invention, support balls are rotatably embedded on the upper and lower sides of the pressure rod, and the support balls are in contact with the grooves of the pressure ring. By setting the support balls, support is provided on one side of the first rotating shaft to improve the stability of the pressing rod.

[0011] The utility model has the following advantages: by arranging four limiting air bags in the protective tube in combination with gaskets and rubber protrusions, it can provide limiting protection for the head of the insulation pipe, and then repeatedly pressing the pressure rod drives the pressure ring to move up and down, and the negative pressure allows air to enter the folding sleeve and the protective tube, and then the air enters the limiting air bag from the first rotating plate, thereby achieving the effect of inflating the limiting air bag and reducing the problem of poor protection effect.

[0017] The present invention will be further described below with reference to the accompanying drawings.

[0018] Please refer to Figure 1-4When the folding sleeve 6 is pulled, the gap between the folding sleeve 6 and the protective sleeve 1 is in a negative pressure state, and the torsion spring on the second rotating shaft is stressed, and the second rotating plate 20 opens downward, and the folding sleeve 6 takes in air. Then, when the pressure ring 5 squeezes the folding sleeve 6 and the spring 7, the gas of the folding sleeve 6 and the protective sleeve 1 will be squeezed through the first through hole 8 and the first rotating plate 11 into the limiting airbag 13, so that the gas in the limiting airbag 13 is filled and the pipe head is clamped. The pressure ring 5 is slidably connected to the protective sleeve 1, and the protective sleeve 1 is fixedly connected with a folding sleeve 6 at the bottom end, and a spring 7 is contacted inside the folding sleeve 6. Four sides away from each other are provided with first through holes 8 in the protective tube 1. The protective tube 1 is fixedly connected with a square frame 9 at the first through hole 8. A first rotating plate 11 is rotatably connected to the square frame 9 through a first rotating shaft 10. A torsion spring is sleeved on the first rotating shaft 10. One side of the first rotating plate 11 contacts a limit block 12. The limit block 12 is fixedly connected to the square frame 9. A limit airbag 13 is fixedly connected to one side of the square frame 9. A second through hole is provided on the upper side of the pressure ring 5. The second through hole is rotatably connected to a second rotating plate 20 through a second rotating shaft. A torsion spring is sleeved on the second rotating shaft. The second rotating plate 20 contacts a limit strip and the limit strip is fixedly connected to one side of the second through hole. When the pipe head needs to be removed, the pressure ring 5 can be brought into contact with the fixed ring 3 to make the first through hole 8 leak out. The limit airbag 13 can be deflated by pushing a single first rotating plate 11 with a small object.

[0019] Among them, the contact strip 16 is evenly fixedly connected to the limiting airbag 13, and the limiting airbag 13 is located on four sides away from each other in the protective tube 1. The contact strip 16 is made of rubber material. By setting the contact strip 16, the friction between the tube head and the limiting airbag 13 in direct contact is reduced, and the wear of the limiting airbag 13 is reduced.

[0020] Among them, the rubber protrusion 15 is fixedly connected to the four sides of the upper end of the gasket 14 that are away from each other. The gasket 14 is glued to the bottom side of the protective tube 1. The gasket 14 is made of rubber material. The gasket 14 and the rubber protrusion 15 contact the tube head, which can reduce the friction between the tube head and the protective tube 1.

[0021] The pressure rod 18 is connected to the groove by rotating through the third rotating shaft 17, and the groove is located on four sides of the pressure ring 5 that are away from each other. By setting the pressure rod 18, the length of the force arm can be increased, which is convenient for pressing and pulling the pressure ring 5.

[0022] Among them, the inner wall of the groove of the pressure ring 5 contacts the support ball 19, and the support ball 19 is rotatably embedded in the upper and lower sides of the pressure rod 18. By setting the support ball 19, the rotation friction of the pressure rod 18 is reduced, and at the same time, support is provided when the pressure rod 18 is pressed and pulled.

[0023] Working principle: Place the tube head in the protective tube 1, the side of the tube head contacts the contact strip 16, one side of the tube head contacts the gasket 14 and the rubber protrusion 15, and then continuously press and pull the pressure rod 18 to make the pressure ring 5 move up and down. When the pressure ring 5 moves up, there is a negative pressure state between the folding sleeve 6 and the protective tube 1. At this time, the second rotating plate 20 is forced to unfold, and air enters between the folding sleeve 6 and the protective tube 1. When the pressure ring 5 is pressed down, the folding sleeve 6 contracts, and the spring 7 contracts at the same time, and squeezes the gas through the first rotating plate 11 into the limiting airbag 13, and gradually squeezes the contact strip 16 into contact with the tube head, and then rotates the sealing plate 2 to provide protection for the tube head. When the tube head needs to be disassembled, you only need to press down the pressure ring 5 and use a small object to push the single first rotating plate 11 to rotate, which can deflate the limiting airbag 13 and facilitate the removal of the tube head.
