AI Technical Summary
In existing sonar transducers, the sealing connection between the hose and the metal connector has size applicability issues, uneven crimping process leads to unstable sealing performance, and crimping failure requires destructive removal, resulting in economic losses.
The system employs a plug and connector threaded connection structure. A hose is pressed into the teeth of the connector by the plug to achieve a sealed connection. An air inlet is provided at the fixed end of the connector for airtightness testing, avoiding the need for water pressure testing.
It enables sealing connections to be completed in ordinary locations, saving manpower, ensuring reliable sealing, and allowing for simple replacement of the valve after leakage, avoiding damage and waste from hydrostatic testing.

Abstract
Description
TECHNICAL FIELD
[0001] The utility model relates to the technical field of underwater acoustic transducer, especially relates to a hose joint sealing connection structure. BACKGROUND
[0002] With the increasingly in-depth development of marine resources and the rapid development of marine military, the range of human activities in the ocean is expanding, and the detection technology related to the ocean is also attracting more and more attention. Sonar technology, as the main technology of ocean exploration, develops rapidly and is widely used in military submarines, offshore oil exploration, seabed topography survey and other fields. In the process of manufacturing sonar transducers, the sealing connection of the hose and the metal is a common structure form in the transducer.
[0003] The existing transducer manufacturing process generally clamps the metal joint and the hose through the clamping ring to form a sealed connection. Considering the specifications of the clamping machine, this method is only suitable for metal joints and hoses within a certain size range. Due to the different clamping strengths, too large joints are easy to damage, too small joints are easy to leak, and uneven stress is easy to fail to meet the sealing requirements. Therefore, the clamping process may bring many uncertain factors, and after the clamping fails, the joint needs to be removed destructively, causing economic losses. SUMMARY
[0004] The utility model aims at providing a hose joint sealing connection structure to solve the problems in the background art.
[0005] To solve the above technical problems, the utility model provides a hose joint sealing connection structure, which comprises a hose, a plug and a joint.
[0006] The hose penetrates into one side of the tapered small head of the plug, and the plug is located in the middle section of the hose, so that the interface of the hose is exposed.
[0007] The interface of the hose is sleeved into the joint, so that the tooth side of the joint is completely inserted, and the plug is connected with the joint through the thread pair.
[0008] Under the action of the plug, the hose is pressed into the tooth of the joint, realizing the sealed connection of the hose and the joint.
[0009] In one embodiment, the fixed end of the joint has an air inlet on one side, which is used for checking the sealing requirements through the air tightness test.
[0010] The utility model provides a kind of hose joint sealing connection structure, need not use press machine, just can be connected in ordinary production place, simple and convenient, save a lot of manpower;Sealing leaks without destructive removal, just need to replace cock again;The fixed end side of joint remains air inlet, just check sealing requirement by air tightness test, need not carry out hydrostatic test, save time, also avoid the damage caused by leakage under hydrostatic test. BRIEF DESCRIPTION OF DRAWINGS
[0011] Figure 1 It is a kind of hose joint sealing connection structure schematic diagram provided by the utility model. DETAILED DESCRIPTION
[0012] The utility model provides a kind of hose joint sealing connection structure further detailed explanation is made in combination with the drawings and specific embodiment.According to the following description, the advantages and characteristics of the utility model will be more clear.It should be noted that the drawings are all very simplified and all use non-precise scale, just to facilitate, clearly assist the purpose of explaining the embodiment of the utility model.
[0013] The utility model provides a kind of hose joint sealing connection structure, including hose 1, cock 2 and joint 3, the hose 1 is inserted into the conical small head side of the cock 2, the cock 2 is located in the middle section of the hose 1, make the interface of hose 1 expose;The interface of hose 1 is sleeved into joint 3, so that the gnawing side of joint 3 is completely inserted, the cock 2 is connected with joint 3 by screw pair.Hose 1 is pressed into the gnawing of joint 3 under the action of cock 2, so as to realize the sealing connection of hose 1 and joint 3.
[0014] The biggest feature of the utility model is that press machine is not needed, just can be connected in ordinary production place.
[0015] The operating method of the above connection structure, characterized in that it comprises the following steps:
[0016] (1) first, the hose 1 is inserted into the conical small head side of the cock 2, the cock 2 is located in the middle section of the hose 1, ensure that the interface of hose 1 is exposed,
[0017] (2) the interface of hose 1 is sleeved into joint 3, ensure that the gnawing side is completely inserted,
[0018] (3) the fixed end side of joint 3 is fixed, the cock 2 is connected with joint 3 by screw pair,
[0019] (4) air is blown from the fixed end side of joint 3 and air tightness is checked.
[0020] The utility model discloses the advantage: through the deformation of hose in advance calculation, the size of the joint's mesh tooth and plug is designed, to accurately control the compression of hose, reach sealing effect, the radial stress of hose is even under the action force of plug, can reach reliable sealing, the operation process can be carried out only in ordinary place, simple and convenient, save a lot of manpower, after the sealing leakage, need not destructive dismantling, only need to replace plug, the fixed end side of joint is left with air inlet, only through air tightness test can check the sealing requirement, need not carry out hydrostatic test, save time, also avoided the damage of leakage under the hydrostatic test.
[0021] The above description is only the description of the preferred embodiment of the utility model, and does not limit the scope of the utility model in any way, and any change or modification made by the ordinary skilled in the art according to the above disclosure is within the protection scope of the claims.
