Description

Technical Field

[0001] This utility model belongs to the field of hose technology, specifically, it relates to a hose structure. Background Technology

[0002] Rubber hoses, as a common type of flexible conduit, are widely used in many fields such as industrial production and daily life. Traditional rubber hoses typically consist of an inner rubber layer, a reinforcing layer, and an outer rubber layer. This simple structure has some shortcomings in practical use.

[0003] Utility model CN222864441U relates to the technical field of hydraulic hose auxiliary devices, specifically a hydraulic hose connection structure. It includes a connecting pipe, with multiple circumferentially arrayed arc clamps forming a circle installed at both ends of the connecting pipe. Hydraulic hoses are installed inside both ends of the connecting pipe, with one end positioned between the arc clamps and the connecting pipe. A fixing platform is installed in the middle of the connecting pipe. The advantages of this utility model are: two hydraulic hoses are connected together via the connecting pipe, with the hydraulic hoses extending into the connecting pipe. Multiple arc clamps are installed on both sides inside the connecting pipe, clamping the hydraulic hoses together with the connecting pipe to fix their position. Threaded rods are installed on the outside of each arc clamp. Multiple slots are opened at both ends of the connecting pipe, with the threaded rods placed within the slots. Locking caps are installed on the threads of the threaded rods to secure the arc clamps, facilitating installation and disassembly.

[0004] However, the aforementioned patents still have the following problems: In applications such as injection molding equipment where high-performance hoses are required, high-pressure hose delivery is necessary. The hose structure in the patents does not perform well in terms of temperature and pressure resistance. Under high pressure, the hose needs to withstand enormous internal pressure. If its pressure resistance is insufficient, it is prone to expansion, deformation, or even rupture, severely affecting delivery efficiency and leading to a decline in the quality of the injection-molded products. Simultaneously, injection molding equipment generates high temperatures during operation. Prolonged operation of the hose in such high-temperature environments alters its material properties, further weakening its pressure resistance and sealing performance, making the delivery process more unstable and difficult to guarantee delivery efficiency.

[0005] In view of this, this utility model is hereby proposed. Utility Model Content

[0029] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions in the embodiments will be clearly and completely described below with reference to the accompanying drawings. The following embodiments are used to illustrate this utility model.

[0030] Example 1: A hose structure, specifically as follows Figure 1 , Figure 2 and Figure 6As shown, it includes a Teflon inner tube 10, which is cylindrical; a heat-resistant structure, which includes a first heat-resistant part and a second heat-resistant part. The first heat-resistant part includes a first stainless steel braided layer 11 fixedly installed on the outer wall of the Teflon inner tube 10, a base layer 12 fixedly installed on the outer wall of the first stainless steel braided layer 11, and a steel heating wire 13 wrapped around the outer wall of the base layer 12; the second heat-resistant part includes a fiber layer 14 disposed outside the Teflon inner tube 10, the inner wall of the fiber layer 14 being in close contact with the outer wall of the steel heating wire 13, an insulation layer 15 fixedly installed on the outer wall of the fiber layer 14, and a corrugated pipe 16 fixedly installed on the outer wall of the insulation layer 15. The device is insulated and protected by a heat-resistant structure. The Teflon inner tube 10 is wrapped by a first stainless steel braided layer 11 and a base layer 12. The position of the steel heating wire 13 is limited by the fiber layer 14 and the base layer 12. The steel heating wire 13 is heated. The fiber layer 14 is wrapped by an insulation layer 15 and a corrugated pipe 16 is used to wrap the insulation layer 15.

[0031] The base layer 12 is made of high-temperature resistant silicone (advantage 1: prevents safety issues caused by damaged circuits coming into contact with the braided layer; advantage 2: fast thermal conductivity, as the easy heating and conductivity of silicone allows the heating layer to conduct heat to the Teflon inner tube more quickly); the fiber layer 14 (good insulation, strong heat resistance, good corrosion resistance, and high mechanical strength, providing better protection for the heating layer and the base layer); the insulation layer 15 (made of AEPS modified polystyrene insulation cotton, approximately three centimeters thick, with advantages: flame retardancy reaching A2 level; three layers are used for insulation, making the heat insulation of the heating tube more stable and avoiding more evaporation and loss; because of the use of three insulation layers, the temperature of the outer skin of the heating tube will not be too high).

[0032] Based on the above, the structure of the Teflon inner tube 10, the first stainless steel braided layer 11, the bottom layer 12, the steel heating wire 13, the fiber layer 14, and the insulation layer 15 achieves the purpose of sealing, heating, and insulating the rubber hose, improving the rubber hose's conveying efficiency, preventing the rubber hose from rupturing and causing the rubber to cool down and become unconvenienced, and improving the stability of the device.

By rotating the threaded connector 18, the second threaded groove 20 is threaded onto the outer wall of the first threaded groove 17, and the threaded connector 18 is installed on the outer wall of the Teflon inner tube 10.

[0036] Specifically, such as Figure 1 and Figure 2 As shown, a first nylon protective sleeve 21 is fixedly installed on the outer wall of one set of threaded joints 18, and a second nylon protective sleeve 22 is fixedly installed on the outer wall of another set of threaded joints 18. A locking buckle 23 is provided on the outer wall of the second nylon protective sleeve 22. The threaded joints 18 are wrapped and protected by the first nylon protective sleeve 21 and the second nylon protective sleeve 22.

[0037] The first nylon protective sleeve 21 and the second nylon protective sleeve 22 are made of impact-resistant nylon with fiber reinforcement, which makes the heating tube more aesthetically pleasing and protects the wiring terminals.

[0038] Specifically, such as Figure 1 , Figure 2 and Figure 3 As shown, an air valve connecting line 24 is provided on the outside of the first nylon protective sleeve 21. One end of the air valve connecting line 24 is fixedly installed inside the first nylon protective sleeve 21, and an aviation plug 27 is fixedly installed on the other end of the air valve connecting line 24.
