Description

Technical Field

[0001] The utility model belongs to the technical field of pipe end protection, and particularly relates to a pipe end protection device for a heat preservation pipe. Background Technique

[0002] The pipe end protection device for a heat preservation pipe is a device specially designed to protect the ends of pipelines or tubes. Its main purpose is to prevent the pipelines from being damaged during transportation, storage, installation and use, so as to extend the service life of the pipelines and improve their service performance. After the steel-sheathed steel heat preservation pipe is manufactured, the pipe orifices are all exposed. During the outdoor stacking process, since there is no protective structure installed at the end of the pipe body of the steel-sheathed steel heat preservation pipe, the steel-sheathed steel heat preservation pipe is very easy to be worn, and the heat preservation layer in the exposed pipe orifice is very easy to absorb moisture, thus affecting the heat preservation function of the materials in the heat preservation layer.

[0003] At the same time, after the heat preservation pipes are produced, they will be stacked together. The heat preservation pipes at the bottom layer may not be stacked firmly, resulting in the stacked heat preservation pipes rolling down, causing property losses and personal injuries. Therefore, a pipe end protection device for a heat preservation pipe is proposed. Summary of the Invention

[0004] The purpose of the utility model is to provide a pipe end protection device for a heat preservation pipe to solve the existing problems.

[0005] To solve the above technical problems, the utility model is realized through the following technical solutions:

[0006] The utility model is a pipe end protection device for a heat preservation pipe, which includes an outer pipe and an inner pipe. External threads are provided on the circumferential sides of both ends of the inner pipe. A protective sleeve is threadedly connected to one end of the inner pipe. Thread grooves are provided in the protective sleeve. The threads on the circumferential side of the inner wall of the thread grooves are internal threads. The external threads are in threaded cooperation with the internal threads. Card slots are provided on the surface of the thread grooves. Multiple groups of limiting blocks are provided on the circumferential side of the protective sleeve. A fixing seat is nested outside the protective sleeve. A circular groove is provided in the fixing seat. Multiple groups of limiting grooves are provided on the circumferential side of the circular groove. The shape and size of the protective sleeve are adapted to those of the fixing seat. The shape and size of multiple groups of limiting blocks are adapted to those of multiple groups of limiting grooves. The positions of multiple groups of limiting blocks are adapted to those of multiple groups of limiting grooves. The protective sleeve and the fixing seat are in clamping fit.

[0007] A through hole is provided on the upper surface of the fixing seat. A round hole is provided on the upper surface of the limiting block. The shape and size of the through hole are adapted to those of the round hole. The positions of the through hole and the round hole are adapted to each other. A pin is provided in the round hole. The pin penetrates through the through hole and is in clamping fit with the round hole.

[0008] A placement groove is provided at the bottom of the protective sleeve. A moisture-proof layer is provided in the placement groove. The material of the moisture-proof layer is any one of non-woven fabric, dust-free paper, high molecular water-absorbing resin and pure cotton fabric.

[0009] The shapes and sizes of the two end faces of the outer tube are adapted to the card slots, and the two end faces of the outer tube are fitted with the card slots in a snap-fit manner.

[0010] After the protective sleeve is nested on the fixing seat, the fixing seat lifts the heat preservation pipe; after the heat preservation pipe is lifted, it is prevented from rubbing against the ground.

[0011] The utility model has the following beneficial effects:

[0012] In the utility model, protective sleeves are threadedly connected to both ends of the inner tube. The moisture-proof layer in the protective sleeve can absorb moisture in the air, preventing the heat preservation layer from absorbing moisture and thus affecting the heat preservation function of the materials in the heat preservation layer. At the same time, the pin in the fixing seat can fix the heat preservation pipe, preventing it from hitting back and forth during emergency braking during transportation and causing damage to the connection. Since the limit blocks on the circumferential side of the protective sleeve are fitted with the limit grooves in the fixing seat, the heat preservation pipe will not rotate back and forth after the protective sleeves and the fixing seats are installed at both ends. When the heat preservation pipe, the protective sleeves and the fixing seats are assembled together, due to the fixing seats, a certain distance will be generated between the surface of the heat preservation pipe and the ground, further avoiding damage caused by uneven ground or rubbing of the surface by stones.

[0013] Of course, when implementing any product of the utility model, it is not necessarily required to achieve all the above-mentioned advantages simultaneously. Description of the Drawings
