Description

Technical Field

[0001] This utility model relates to the field of PTFE sleeve technology, and in particular to a PTFE sleeve that is easy to bend and position. Background Technology

[0002] PTFE tubing is a type of corrosion-resistant flexible tubing commonly used in chemical, mechanical, and other fields. Due to its stable chemical properties, electrical insulation properties, and anti-aging properties, PTFE tubing ensures safe transmission in various hazardous environments such as high temperatures and strong corrosive conditions.

[0003] When using PTFE tubing for equipment connection, if an obstacle exists between the two devices to be connected, the PTFE tubing needs to be bent to bypass the obstacle. Existing methods typically use corrugated PTFE tubing for bending. However, after bending, the corrugated PTFE tubing is difficult to position, causing the outer surface to easily adhere to the surrounding obstacle, which is inconvenient. Furthermore, when the corrugated PTFE tubing is impacted, it is easily squeezed between itself and the obstacle, leading to damage and reducing its protective properties. Therefore, it is necessary to propose a PTFE tubing that is easy to bend and position to solve these problems. Utility Model Content

[0004] The purpose of this invention is to provide a PTFE sleeve that is easy to bend and position, in order to solve the problem mentioned in the background art where, when using PTFE sleeves to connect equipment, if there is an obstacle between the two devices to be connected, the PTFE sleeve needs to be bent to bypass the obstacle. Existing methods generally use corrugated PTFE sleeves for bending; however, after bending, it is not easy to position the corrugated PTFE sleeve, causing the outer surface of the sleeve to easily adhere to the surrounding area of ​​the obstacle, which brings inconvenience to the use of the PTFE sleeve. Furthermore, when the corrugated PTFE sleeve is impacted, it is easily squeezed between itself and the obstacle, causing damage and reducing the protective function of the PTFE sleeve.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a PTFE sleeve that is easy to bend and position, comprising a corrugated PTFE tube, wherein a steel wire braided sleeve is fixedly connected to the outside of the corrugated PTFE tube, a fixed sleeve is fixedly connected to the outside of the steel wire braided sleeve, and a rotating sleeve is rotatably connected to the outside of the fixed sleeve.

[0006] The rotating sleeve is provided with a bending assembly on its exterior. The bending assembly includes a fixing block, a rotating shaft, a connecting block, and a positioning plate. The interior of the fixing block is rotatably connected to the exterior of the rotating shaft. The top end of the rotating shaft is fixedly connected to the bottom of the connecting block. The exterior of the connecting block is fixedly connected to one end of the positioning plate.

[0007] The positioning plate is internally provided with a positioning assembly, which includes a positioning bolt, a connecting plate, a first washer, a second washer, and a positioning nut. The outside of the positioning bolt is inserted into the inside of the connecting plate, the outside of the positioning bolt is inserted into the inside of the first washer, the outside of the positioning bolt is inserted into the inside of the second washer, and the outside of the positioning bolt is threadedly connected to the inside of the positioning nut.

[0008] Preferably, there are multiple fixing sleeves, and the multiple fixing sleeves are arranged in an array along the length direction of the corrugated PTFE tube.

[0009] Preferably, the bottom of the fixing block is fixedly connected to the outside of the rotating sleeve.

[0010] Preferably, the outside of the positioning bolt is inserted into the inside of the positioning plate.

[0011] Preferably, the first gasket is located on the side of the connecting plate, and the second gasket is located on the side of the positioning plate.

[0012] The technical effects and advantages of this utility model are as follows:

[0013] By coordinating the bending and positioning components, when an obstacle appears between two devices needing to connect corrugated PTFE tubes, requiring bending of the tubes, a suitable connecting plate can be selected and pulled according to the actual bending situation. This causes the connecting plate and positioning plate to fold, and the positioning plate will cause the corresponding corrugated PTFE tube to bend. The tightness between the connecting plate and positioning plate can be adjusted using the positioning nut. The compression of the first and second washers creates damping between the connecting plate and positioning plate, preventing the connecting plate and positioning plate from resetting. This facilitates the positioning of the corrugated PTFE tube and prevents the outside of the tube from easily sticking to the surrounding obstacle, thus bringing convenience to the use of the corrugated PTFE tube. Furthermore, the use of multiple fixing sleeves and the positioning and connecting plates set on the outside of the fixing sleeves can protect the outside of the PTFE sleeve, preventing damage from collisions and thus improving the protection of the PTFE sleeve.

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0019] This utility model provides, for example Figures 1-3 The PTFE sleeve shown is easy to bend and position, including a corrugated PTFE tube 1 and a connecting plate 10. A steel wire braided sleeve 2 is fixedly connected to the outside of the corrugated PTFE tube 1. A fixing sleeve 3 is fixedly connected to the outside of the steel wire braided sleeve 2. A rotating sleeve 4 is rotatably connected to the outside of the fixing sleeve 3. The steel wire braided sleeve 2 can be used to improve the protection of the corrugated PTFE tube 1.

[0020] In addition, a bending assembly is provided on the outside of the rotating sleeve 4. The bending assembly includes a fixing block 5, a rotating shaft 6, a connecting block 7, and a positioning plate 8. The inside of the fixing block 5 is rotatably connected to the outside of the rotating shaft 6. The top of the rotating shaft 6 is fixedly connected to the bottom of the connecting block 7. The outside of the connecting block 7 is fixedly connected to one end of the positioning plate 8. There are multiple fixing sleeves 3, and the multiple fixing sleeves 3 are arranged in an array along the length direction of the corrugated PTFE tube 1. The bottom of the fixing block 5 is fixedly connected to the outside of the rotating sleeve 4. When there is an obstacle between two devices that need to connect corrugated PTFE tubes 1, and it is necessary to bend the corrugated PTFE tube 1, a suitable connecting plate 10 can be selected and pulled according to the actual bending situation, so that the connecting plate 10 and the positioning plate 8 fold together. The positioning plate 8 will drive the corresponding corrugated PTFE tube 1 to bend, thus facilitating the bending of the corrugated PTFE tube 1.

[0021] Finally, a positioning assembly is provided inside the positioning plate 8. The positioning assembly includes a positioning bolt 9, a first washer 11, a second washer 12, and a positioning nut 13. The outside of the positioning bolt 9 is inserted into the inside of the connecting plate 10, and the outside of the positioning bolt 9 is inserted into the inside of the first washer 11. The outside of the positioning bolt 9 is inserted into the inside of the second washer 12, and the outside of the positioning bolt 9 is threadedly connected to the inside of the positioning nut 13. The outside of the positioning bolt 9 is inserted into the inside of the positioning plate 8. The first washer 11 is located on the side of the connecting plate 10, and the second washer 12 is located on the side of the positioning plate 8. The tightness between the connecting plate 10 and the positioning plate 8 can be adjusted using the positioning nut 13. The compression of the first washer 11 and the second washer 12 creates damping between the connecting plate 10 and the positioning plate 8, making it less likely for the connecting plate 10 and the positioning plate 8 to reset. This facilitates the positioning of the corrugated PTFE tube 1 and prevents the outside of the corrugated PTFE tube 1 from easily sticking to the surrounding obstacles, thus bringing convenience to the use of the corrugated PTFE tube 1. Furthermore, the multiple fixing sleeves 3 and the positioning plate 8 and connecting plate 10 set on the outside of the fixing sleeves 3 can protect the outside of the corrugated PTFE tube 1, preventing the corrugated PTFE tube 1 from being damaged by collision, thereby improving the protection of the corrugated PTFE tube 1.

[0022] Working principle: When an obstacle appears between two devices with corrugated PTFE tubes 1 to be connected, and the corrugated PTFE tubes 1 need to be bent, a suitable connecting plate 10 can be selected and pulled according to the actual bending situation, causing the connecting plate 10 and the positioning plate 8 to fold. The positioning plate 8 will drive the corresponding corrugated PTFE tube 1 to bend. Then, the tightness between the connecting plate 10 and the positioning plate 8 can be adjusted using the positioning nut 13. The compression of the first washer 11 and the second washer 12 creates damping between the connecting plate 10 and the positioning plate 8, making it less likely for the connecting plate 10 and the positioning plate 8 to reset. This facilitates the positioning of the corrugated PTFE tube 1 and prevents the outside of the corrugated PTFE tube 1 from easily sticking to the surrounding area of ​​the obstacle, bringing convenience to the use of the corrugated PTFE tube 1. In addition, the multiple fixing sleeves 3 and the positioning plate 8 and connecting plate 10 set on the outside of the fixing sleeves 3 can protect the outside of the corrugated PTFE tube 1, avoiding the problem of the corrugated PTFE tube 1 being damaged by collision, thereby improving the protection of the corrugated PTFE tube 1.
