Abstract
Description
Technical Field
[0001] The present application relates to the technical field of rubber tube inspection, and in particular to an improved rubber tube inspection tool. Background Art
[0002] A diesel engine is an engine that burns diesel to obtain energy release, and is a heat engine that converts chemical energy into mechanical energy. With the improvement of diesel engines in other aspects, its performance is getting closer and closer to that of gasoline engines, and its noise and vibration are not much greater than those of gasoline engines. Therefore, more and more diesel engines have gained an important position and been adopted in life. The oil pipeline of a diesel engine generally uses copper pipes, rubber hoses or nylon pipes. In order to ensure the normal operation of the diesel engine, the air tightness of the oil pipeline must be ensured. Therefore, it is necessary to test the air tightness of the rubber pipe. In the prior art, the air tightness test of rubber pipes is mostly done by manually sealing, pressing, immersing, and checking whether bubbles appear one by one to determine whether the rubber pipe is leaking.
[0003] After the existing rubber tubes are produced, they need to be inspected for sealing performance to prevent problems such as oil leakage during use. The current detection method is to connect the rubber tube to the air cylinder, inflate the rubber tube by releasing air from the air cylinder, and then observe whether there is leakage on the water surface. However, the conventional fixing method is to directly connect the rubber tube to the air cylinder, which often results in the connection not being tight enough, which is prone to underwater leakage, thus affecting the inspection effect.
[0004] Therefore, a new improved rubber tube check fixture is provided to solve the above problems. Utility Model Content

[0032] The present application is further described in detail below through drawings and examples.
[0033] Reference Figures 1 to 4 The embodiment of the present application provides an improved rubber tube inspection fixture, including a base plate 1 and a lifting assembly 2. A detection assembly 3 is arranged inside the base plate 1. The detection assembly 3 includes a rubber tube 31, an air outlet nozzle 36 and an air pump 34. A thread groove 37 is provided inside the air outlet nozzle 36. A thread 38 is installed on the outer surface of the rubber tube 31. A rotating ring 39 is screwed on the outer surface of the thread 38. An external thread 310 is provided on the outer surface of the rotating ring 39. The external thread 310 is screwed inside the thread groove 37.
[0034] Reference Figures 1 to 4 In one aspect of the present embodiment, a rotating block 311 is fixedly connected to the outer surface of the rotating ring 39, and the detection component 3 also includes a connecting shell 32, a tube body 33 is fixedly installed between the inner and outer walls of the connecting shell 32, one end of the tube body 33 is fixedly installed inside the air outlet nozzle 36, and a gas delivery pipe 35 is fixedly installed between the side wall of the connecting shell 32 and the inside of the air pump 34. When the user is testing the rubber tube 31, water is injected into the groove hole 21. After the water injection is completed, the rotating ring 39 is driven to rotate by rotating the rotating block 311. The rotating ring 39 rotates so that the external thread 310 and the thread groove 37 are rotated and docked, thereby making the air outlet nozzle 36 is docked with the rubber tube 31 by means of screw connection, so as to avoid the problem that the docking is not tight enough and underwater leakage may occur easily, thereby affecting the inspection effect. Then, the air pump 34 is turned on to inflate the gas delivery tube 35. The inflation of the gas delivery tube 35 inflates the interior of the connecting shell 32. The inflation of the interior of the connecting shell 32 inflates the tube body 33. The inflation of the tube body 33 inflates the rubber tube 31. When the inflation is completed, the lifting plate 23 is driven downward by turning on the electric push rod 26. The movement of the lifting plate 23 causes the rubber tube 31 to move downward into the water, so that it is convenient for the inspector to check whether there are bubbles generated underwater, thereby accelerating the inspection efficiency.
[0035] Reference Figures 1 to 4 In one aspect of the present embodiment, the lifting assembly 2 includes a slot 21 and a lifting plate 23 opened inside the bottom plate 1, the air outlet nozzle 36 is fixedly connected to the upper part of the lifting plate 23, a water-permeable hole 24 is opened between the inner and outer walls of the lifting plate 23, a fixed side plate 25 is fixedly installed on the outer surface of the bottom plate 1, and an electric push rod 26 is fixedly installed on the side wall of the fixed side plate 25, one end of the electric push rod 26 is fixedly connected to the outer surface of the lifting plate 23, and a supporting foot 22 is fixedly connected to the lower part of the bottom plate 1. When the inflation is completed, the lifting plate 23 is driven to move downward by turning on the electric push rod 26. The movement of the lifting plate 23 causes the rubber tube 31 to move downward into the water, which makes it convenient for the inspector to check whether bubbles are generated underwater, thereby speeding up the detection efficiency.
[0036] Working principle: When the user is testing the rubber tube 31, water is injected into the groove hole 21. After the water injection is completed, the rotating ring 39 is driven to rotate by rotating the rotating block 311. The rotating ring 39 rotates so that the external thread 310 and the thread groove 37 are rotated and docked, and then the air outlet nozzle 36 is docked with the rubber tube 31. The docking is performed by screwing, which avoids the problem of insufficient docking and underwater leakage, thereby affecting the inspection effect. Then, the air pump 34 is turned on to inflate the gas delivery tube 35. The inflation of the gas delivery tube 35 inflates the inside of the connecting shell 32. The inflation of the inside of the connecting shell 32 inflates the tube body 33. The inflation of the tube body 33 inflates the rubber tube 31. After the inflation is completed, the electric push rod 26 is turned on to drive the lifting plate 23 to move downward. The movement of the lifting plate 23 causes the rubber tube 31 to move down into the water, which makes it convenient for the inspector to check whether there are bubbles generated underwater, thereby speeding up the inspection efficiency.
