Description

Technical Field

[0001] The utility model relates to the field of PIR tubes, in particular to a PIR connecting tube with reliable positioning. Background Art

[0002] PIR (Polyisocyanurate Foam, Chinese name is "polyisocyanurate") pipe, commonly used for cold preservation pipe. PIR is a flexible pipe. If the PIR pipe is set too long, the middle part will collapse downward. Therefore, in actual use, the PIR will be divided into several short pipes of appropriate lengths, and multiple short pipes will be spliced ​​together to form a delivery pipeline. At the connection of each PIR pipe, it is usually necessary to design a connecting pipe to connect the PIR pipes at both ends. In order to minimize the impact of collapse on the delivery pipeline, a pipe bracket must be installed on the connecting pipe. At the same time, because the pipe bracket is made of hard material, the hardness of the finished connecting pipe is usually greater than that of the general PIR pipe.

[0003] However, although the hardness of the connecting pipe is improved, the connecting pipe is made of a material similar to that of the general PIR pipe. When the pipe bracket is firmly connected to the connecting pipe, the connecting pipe will inevitably be squeezed, causing the connecting part between the connecting pipe and the pipe bracket to be severely bent and more prone to cracking, resulting in poor insulation effect of the connecting pipe. Therefore, a PIR connecting pipe with reliable positioning is designed. Utility Model Content

[0004] The utility model aims to provide a PIR connecting pipe with reliable positioning to solve the above problems.

[0005] In order to achieve the above-mentioned object, the embodiment of the utility model provides a PIR connecting pipe with reliable positioning, comprising: a pipe body, wherein the outer wall of the pipe body is provided with a plurality of assembly grooves along the axial direction;

[0011] The support rod is detachably arranged in the through hole.

[0012] Furthermore, the support rods are evenly distributed along the circumference of the tube body.

[0013] Furthermore, there are four support rods.

[0023] 2. Support rod. DETAILED DESCRIPTION

[0024] Now the utility model is further described in detail with reference to the accompanying drawings. These drawings are simplified schematic diagrams, which only illustrate the basic structure of the utility model in a schematic manner, and therefore only show the components related to the utility model.

[0025] like Figure 1As shown, at least one embodiment provides a PIR connecting pipe with reliable positioning, including: a pipe body 1, wherein the two ends of the pipe body 1 are respectively provided with matching protrusions 13, which are used to assist the pipe body 1 in splicing with other PIR pipes. The pipe body 1 is used to connect the PIR pipes at the front and rear ends, and the pipe body 1 is suitable for installing a pipe bracket to receive the entire pipeline. It should be noted that, on the one hand, the installation of the pipe bracket can also assist the pipe body 1 as a positioning component when splicing with other PIR pipes, and the form of the pipe bracket buckling the pipe body 1 can also be used as an auxiliary connection between the pipe body 1 and other PIR pipes. Therefore, the installation position of the pipe bracket on the pipe body 1 needs to be positioned, and other installation steps are performed. On the other hand, when the pipe bracket is firmly connected to the pipe body 1, it will inevitably squeeze the pipe body 1, so that the connection part between the pipe body 1 and the pipe bracket is severely bent, and it is more likely to crack, resulting in poor insulation effect of the pipe body 1.

[0026] In order to solve the above problems, Figure 1 As shown, the outer wall of the tube body 1 is provided with a plurality of assembly grooves 11 along the axial direction. The assembly grooves 11 are provided in a ring shape. Preferably, there are two assembly grooves 11. The two assembly grooves 11 are symmetrically arranged at the two ends of the tube body 1, and the assembly grooves 11 correspond to the tube bracket. That is, by thickening the tube body 1 of the connecting tube and pre-opening the assembly grooves 11 in advance, it is convenient to insert the sleeve part of the tube bracket into the assembly grooves 11 when installing the tube bracket, so as to ensure reliable positioning of the tube bracket, avoid the problem of asymmetric force application position on the tube body 1 caused by asymmetric installation, and then damage and cracking of the fixture tube body 1. On the other hand, since the tube body 1 is provided with a plurality of assembly grooves 11 along the axial direction, the tube body 1 is divided into multiple sections, so the part with the assembly grooves 11 is easier to bend than other parts. In order to solve the above problems, Figure 1 As shown, a plurality of support rods 2 are arranged inside the pipe body 1, and the support rods 2 sequentially penetrate the assembly grooves 11 along the axial direction. Preferably, there are six support rods 2. The support rods 2 can strengthen the strength of the assembly groove 11 to reduce the risk of the pipe body 1 being partially bent in the assembly groove 11.

[0027] In order to prevent the support rod 2 from interfering with the installation of the pipe bracket, in some embodiments, as preferred, Figure 2 As shown, the pipe body 1 is provided with a plurality of through holes 12 along the circumferential direction, and the through holes 12 are sequentially connected with the assembly grooves 11. The support rods 2 are detachably arranged in the through holes 12. When installing the pipe bracket, each support rod 2 can be pulled out from the through holes 12 to facilitate the insertion of the clamp part of the pipe bracket into the assembly groove 11. After the pipe bracket is installed, each support rod 2 is inserted into the through holes 12 to support the assembly groove 11.

[0028] In order to further ensure the reliability of the supporting effect of the support rods 2 , the support rods 2 are evenly distributed along the circumference of the pipe body 1 .

[0029] As an option, Figure 3 As shown, there are four support rods 2. Compared with six support rods 2, in the case of four support rods 2, the support rods 2 are more dispersed, which can provide more installation angles for the pipe bracket.

[0030] It is worth mentioning that the technical features such as other components involved in this utility model patent application should be regarded as prior art. The specific structure, working principle and possible control method and spatial layout method of these technical features can be selected by conventional methods in the field and should not be regarded as the invention point of this utility model patent.

For those skilled in the art, the utility model may have various modifications and changes.
