Description

Technical Field

[0001] This utility model relates to the field of air brake technology, specifically to an air brake hose. Background Technology

[0002] Currently, brake hoses sold on the market are all brake hose assemblies with connectors. Based on the different types of vehicle braking, they are divided into hydraulic brake hoses, pneumatic brake hoses, and vacuum brake hoses. Based on the different materials, they are divided into rubber brake hoses and nylon brake hoses.

[0003] The existing air brake hose cannot solve the problem of external corrosion, and thermal expansion and contraction can cause the hose to break and become unusable. At the same time, it cannot guarantee that the device structure will not fall off. Therefore, we propose an air brake hose. Utility Model Content

[0004] The purpose of this invention is to provide an air brake hose to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] An air brake hose includes an inner rubber layer, a hose mechanism fixedly disposed on the outer side of the inner rubber layer, the hose mechanism including a reinforcing layer, a reinforcing layer fixedly disposed on the outer side of the inner rubber layer, an outer rubber layer fixedly disposed on the outer side of the reinforcing layer, a heat insulation layer movably disposed on the outer side of the outer rubber layer, a metal corrugated hose fixedly disposed on the outer side of the heat insulation layer, and an anti-detachment mechanism fixedly disposed on one side surface of the outer rubber layer.

[0007] Preferably, the anti-detachment mechanism includes an assembly tube, an assembly tube fixedly disposed on one side surface of the outer adhesive layer, a connector fixedly disposed on one side of the assembly tube, a threaded groove formed inside the connector, a retaining groove formed on the outer surface of the assembly tube, a first fixing tube movably disposed on the outer surface of the assembly tube, a connector fixedly disposed on one side of the first fixing tube, a second fixing tube fixedly disposed on one side of the connector, several bolts movably disposed at the top ends of the first and second fixing tubes, and several retaining blocks fixedly disposed on the inner surfaces of the first and second fixing tubes. This is achieved by providing an assembly tube on one side of the outer adhesive layer, welding a connector to one side of the assembly tube, and the connector's inner... The assembly tube has a threaded groove, and the outer surface of the assembly tube has a slot. A first fixing tube is movably installed on the outer surface of the assembly tube. A connector is installed on one side of the first fixing tube with a screw, and a second fixing tube is installed on the other side of the connector with a screw. Two bolts are installed at the top of the first and second fixing tubes. Multiple locking blocks are welded to the inner surfaces of the first and second fixing tubes. During the installation of the device, the connector is installed by a knob. After the installation is completed, the locking blocks on the first and second fixing tubes are inserted into the slots, and the first and second fixing tubes are fixed with bolts. Finally, the metal corrugated hose is welded to the tail of the first and second fixing tubes to ensure that the device structure will not fall off.

[0008] Preferably, the number and size of the card blocks and card slots are the same. By setting the size and number of the card blocks and card slots to be the same, it is easy for the card blocks to be inserted into the card slots, ensuring the normal use of the device.

[0009] Preferably, the diameter of the corrugated metal hose is slightly larger than the diameter of the insulation layer, with a gap between them. The slightly larger diameter of the corrugated metal hose compared to the insulation layer ensures that the internal structure of the device can move within a small range during pneumatic braking.

[0010] Preferably, a threaded plug is movably disposed inside the threaded groove, and a knob cover is fixedly disposed on one side of the threaded plug. By disposing of the threaded plug and the knob cover inside the threaded groove, the threaded plug can be installed into the threaded groove at the time of manufacture to ensure that dust does not enter the interior.

[0011] Preferably, a plurality of anti-slip strips are fixedly provided on the outer surface of the connector. By providing multiple anti-slip strips on the outer surface of the connector, the friction can be increased during installation or disassembly, thereby facilitating installation and disassembly.

[0012] Compared with the prior art, the beneficial effects of this utility model are:

[0013] 1. This air brake hose comprises an inner rubber layer with a reinforcing layer on the outside, an outer rubber layer on the outside of the reinforcing layer, a heat insulation layer on the outside of the outer rubber layer, and a metal corrugated hose on the outside of the heat insulation layer. During operation, the outer side may be corroded, and the metal corrugated hose protects it from corrosion. Furthermore, the heat insulation layer prevents the internal structure from expanding and contracting due to temperature changes, which could lead to air leakage and malfunction. This mechanism extends the service life of the device structure.

[0014] 2. This air brake hose comprises an assembly tube on one side of the outer rubber layer, a connector welded to one side of the assembly tube, a threaded groove inside the connector, a retaining groove on the outer surface of the assembly tube, a first fixing tube movably mounted on the outer surface of the assembly tube, a connector mounted on one side of the first fixing tube with screws, and a second fixing tube mounted on the other side of the connector with screws. Two bolts are installed at the top of the first and second fixing tubes. Multiple retaining blocks are welded to the inner surfaces of the first and second fixing tubes. During installation, the connector is installed using a knob. After installation, the retaining blocks on the first and second fixing tubes are engaged in the retaining grooves, and the first and second fixing tubes are secured with bolts. Finally, a metal corrugated hose is welded to the tail of the first and second fixing tubes, thus ensuring that the device structure will not detach. Attached Figure Description
