Description

Technical Field

[0001] The utility model relates to the technical field of tube retainers, and specifically relates to a tube retainer. Background Technique

[0002] Tubes are pipes for fixing, supporting and heat dissipation, and are usually used in shell-and-tube heat exchangers and the research on atmospheric pressure high-efficiency rectification methods. When installing tubes in equipment, a tube retainer is required to isolate each pipe in the tubes, and at the same time, it also plays a role in guiding the pipes and keeping them in a fixed position.

[0003] At present, when most tube retainers are in use, the tubes are inserted into the retainer and fixed with fixing bolts. Using this method, during maintenance and disassembly, due to the small size of the bolts, the bolts are prone to damage or loss during repeated disassembly and assembly, and the disassembly and installation efficiency is low, thus making it inconvenient to use. Content of the Utility Model

[0004] The purpose of the utility model is to provide a tube retainer to solve the problems raised in the above background technique.

[0005] To achieve the above purpose, the utility model provides the following technical solution: A tube retainer, including a retainer body, an installation cylinder is installed on the inner wall of the retainer body, an installation groove is opened on one side inside the installation cylinder, an installation ring two is fixedly connected to the inner wall of the installation groove, a plurality of elastic metal soft plates are fixedly connected to one side of the installation ring two, a threaded groove is opened on one side of the inner wall of the installation cylinder, a threaded cylinder is threadedly connected to the inner wall of the threaded groove, a rotating ring is fixedly connected to one end of the threaded cylinder, an inclined groove is opened on one side of the inner wall of the threaded cylinder and near the edge, and the inner wall of the inclined groove is slidably connected to one side of the plurality of elastic metal soft plates.

[0006] As a further preferred of this technical solution, a rubber cylinder is fixedly connected to the other side of the inner wall of the installation cylinder.

[0009] As a further preferred of this technical solution, a fixing ring is fixedly connected to the outer wall of the retainer body.

[0010] The utility model provides a tube cage, which has the following beneficial effects:

[0011] (1) By rotating the rotating ring of the utility model, the threaded cylinder rotates in the threaded groove. When the threaded cylinder moves a certain distance in the threaded groove, the threaded cylinder separates from the elastic metal soft plate, releasing the restriction of the elastic metal soft plate. The elastic force of the elastic metal soft plate itself will separate each elastic metal soft plate, releasing the restriction of the tubes, so that the tubes can be taken out from the cage body. The design of the elastic metal soft plate and the threaded cylinder is simple in structure and convenient in operation, and the tubes can be quickly disassembled. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0017] Next, the technical solutions in the embodiments of the utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the utility model.

[0018] The utility model provides a technical solution: as Figure 1 - Figure 4As shown in the figure, in this embodiment, a tube cage includes a cage body 1. An installation cylinder 2 is installed on the inner wall of the cage body 1. An installation groove 14 is opened on one side inside the installation cylinder 2. An installation ring two 7 is fixedly connected to the inner wall of the installation groove 14. A plurality of elastic metal soft plates 8 are fixedly connected to one side of the installation ring two 7. A threaded groove 12 is opened on one side of the inner wall of the installation cylinder 2. A threaded cylinder 9 is threadedly connected to the inner wall of the threaded groove 12. One end of the threaded cylinder 9 is fixedly connected to a rotating ring 3. An inclined groove 13 is opened on one side of the inner wall of the threaded cylinder 9 and near the edge. The inner wall of the inclined groove 13 is slidably connected to one side of the plurality of elastic metal soft plates 8. By rotating the rotating ring 3, the threaded cylinder 9 rotates in the threaded groove 12. When the threaded cylinder 9 moves a certain distance in the threaded groove 12, the threaded cylinder 9 is separated from the elastic metal soft plate 8, releasing the restriction on the elastic metal soft plate 8. The elastic force of the elastic metal soft plate 8 itself will separate each elastic metal soft plate 8, releasing the restriction on the tube, so that the tube can be taken out from the cage body 1. The design of the elastic metal soft plate 8 and the threaded cylinder 9 has a simple structure and convenient operation, and the tube can be quickly disassembled. A plurality of installation cylinders 2 are installed on the cage body 1, and the installation and disassembly of each installation cylinder 2 are the same.

[0019] As Figure 4 shown, a rubber cylinder 11 is fixedly connected to the other side of the inner wall of the installation cylinder 2. Through the structural design of the rubber cylinder 11, it can play a role in buffering and shock absorption, reducing the wear and noise between the tube and the installation cylinder 2, and improving the stability and service life of the equipment.

[0020] As Figure 1 、 Figure 3 and Figure 4 shown, an installation ring one 5 is fixedly connected to one side of the outer wall of the installation cylinder 2. A plurality of fixing bolts 6 are threadedly connected to one side of the installation ring one 5. One ends of the plurality of fixing bolts 6 are threadedly connected to one side of the cage body 1. By loosening the fixing bolts 6, the installation cylinder 2 can be disassembled from the cage body 1, facilitating the replacement of the installation cylinder 2.

[0021] As Figure 1 、 Figure 3 and Figure 4 shown, a plurality of reinforcing ribs 10 are fixedly connected to one side of the installation ring one 5. One sides of the plurality of reinforcing ribs 10 are fixedly connected to the outer wall of the installation cylinder 2. Through the structural design of the plurality of reinforcing ribs 10, the strength of the installation cylinder 2 can be improved, preventing the installation cylinder 2 from deforming after long-term use.

[0022] As Figure 1 and Figure 2 shown, a fixing ring 4 is fixedly connected to the outer wall of the cage body 1. Through the structural design of the fixing ring 4, the cage body 1 is placed inside the pipeline, and the fixing structure connects the fixing ring 4 with the pipeline, thereby installing the cage body 1 inside the equipment.

[0023] The utility model provides a tube cage, and the specific working principle is as follows:

[0024] When installing the tubes in the cage, first pass the tubes through the rotating ring 3 and the mounting cylinder 2, and then rotate the rotating ring 3 to make the threaded cylinder 9 rotate in the threaded groove 12. When the threaded cylinder 9 moves a certain distance in the threaded groove 12, the inclined groove 13 of the threaded cylinder 9 contacts the elastic metal soft plate 8, and one end of the threaded cylinder 9 presses on the plurality of elastic metal soft plates 8. At the same time, the inner walls of the plurality of elastic metal soft plates 8 wrap the outer surface of the tubes, so that the elastic metal soft plates 8 fix the tubes. When removing the tubes from the cage body 1, rotate the rotating ring 3 in the reverse direction, and the threaded cylinder 9 releases the restriction on the elastic metal soft plates 8. The elastic force of each elastic metal soft plate 8 itself will separate each elastic metal soft plate 8 to release the restriction on the tubes, so as to draw out the tubes from the cage body 1. When the mounting cylinder 2 is deformed and needs to be replaced after long-term use, loosen the fixing bolts 6 to remove the mounting cylinder 2 from the cage body 1.

[0025] Although the embodiments of the present utility model have been shown and described, those of ordinary skill in the art can understand that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principle and spirit of the present utility model. The scope of the present utility model is defined by the appended claims and their equivalents.
