Description

Technical Field

[0001] The utility model belongs to the technical field of connectors, and particularly relates to a connector for preventing hose loosening. Background Art

[0002] Hose connectors are important components for connecting hoses to equipment or pipes and are widely used in liquid and gas transmission systems. They are usually made of metal or plastic materials and can withstand certain pressures and temperatures to ensure the safe transmission of media. These connectors come in various types, including clamp type, threaded type, and flange type, and are applicable to various industries such as industrial manufacturing, automotive, and agriculture. After long-term use of the hose, the connection between the hose and the connector is prone to loosening. The main reason is that after repeated bending and stretching of the hose, the sealing structure at the connector gradually loosens. In addition, environmental factors such as vibration, corrosion, and aging may also cause the connector to lose its original firmness, leading to loosening. The conventional countermeasure is to use connectors with anti-loosening designs, such as lock nuts or special sealing structures, to enhance the connection stability. However, the drawback of this method is that although using connectors with anti-loosening designs can enhance stability, the installation may be complex, increasing the operation difficulty. Therefore, a new structure is proposed to solve the above problems. Summary of the Invention

Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0024] Please refer to Figures 1 to 5 : A joint for preventing a hose from loosening, comprising: a joint body 100, a compression ring 200, and a docking ring 310. An annular area away from the center of the bottom of the joint body 100 is recessed upward to form a docking groove 110. A first sealing ring 120 is adhesively bonded to the side surface of the docking groove 110 close to the center.

[0025] A second sealing ring 130 is adhesively bonded to the inner top of the docking groove 110. An internal thread groove is provided on the side surface of the docking groove 110 away from the center. A compression ring 200 is provided below the joint body 100. A docking pipe 210 is provided on the top of the compression ring 200. A thread matching the specification of the internal thread groove is provided on the outside of the docking pipe 210.

[0026] A third sealing ring 220 is adhesively bonded to the inner side of the docking pipe 210. A hose body 300 is provided below the compression ring 200. A docking ring 310 is provided on the top of the hose body 300. An embedding groove is formed by the upward depression of the annular area away from the center of the bottom of the docking ring 310. The top of the hose body 300 is adhesively bonded to the inside of the embedding groove.

[0027] The radius length of the compression ring 200 matches the radius length of the joint body 100. The radius length of the docking pipe 210 matches the radius length of the docking groove 110. The height of the docking pipe 210 matches the depth of the docking groove 110.

[0028] The inner circle radius length of the docking pipe 210 is greater than the outer circle radius length of the docking ring 310. The sum of the thickness of the docking pipe 210 and the thickness of the docking ring 310 matches the width of the docking groove 110, ensuring that the docking pipe 210 can be tightly rotationally connected to the docking groove 110.

[0029] The height of the docking ring 310 is equal to the height of the docking pipe 210. Both the docking pipe 210 and the docking ring 310 are made of stainless steel. Both the inner side and the outer side of the docking ring 310 are matte surfaces, increasing the friction on the outer side and the inner side of the docking ring 310 and enhancing the anti-loosening effect.

[0030] The docking pipe 210 and the compression ring 200 are of an integral structure. The bottom of the compression ring 200 is a frustum-shaped structure with a gradually decreasing diameter from top to bottom. A through hole is provided at the center of the bottom of the compression ring 200. The radius length of the through hole matches the radius length of the docking ring 310, ensuring that the docking ring 310 and the hose body 300 can pass through the compression ring 200 and be inserted into the inside of the docking groove 110.

[0031] The first sealing ring 120, the second sealing ring 130, and the third sealing ring 220 are all made of rubber. The height of the first sealing ring 120 matches the depth of the docking groove 110, the width of the second sealing ring 130 matches the width of the docking groove 110, and the height of the third sealing ring 220 matches that of the docking pipe 210.

[0032] The side of the first sealing ring close to the center of the circle is adhesively fixed to the side of the docking groove 110 close to the center of the circle. The top of the second sealing ring 130 is adhesively fixed to the upper part inside the docking groove 110. The outer side of the third sealing ring 220 is adhesively fixed to the inner side of the docking pipe 210. Both the first sealing ring 120 and the third sealing ring 220 are in close contact with the docking ring 310, so as to effectively prevent the docking ring 310 from loosening inside the docking groove 110, and then effectively prevent the hose body 300 from loosening from the joint body 100. At the same time, the first sealing ring 120, the second sealing ring 130, and the third sealing ring 220 can also effectively prevent leakage.

[0033] Example 1: Please refer to Figures 1 to 5 , in actual use, first insert the top of the hose body 300 upward along the embedding groove opened at the bottom of the docking ring 310, and then use neoprene glue to adhesively fix the hose body 300 to the inside of the embedding groove, so that the hose body 300 can be more easily inserted into the docking groove 110 through the docking ring 310. Then pick up the pressing ring 200, insert the docking ring 310 upward along the bottom of the pressing ring 200, and make the docking ring 310 pass through the top of the docking pipe 210, so as to temporarily place the pressing ring 200 outside the hose body 300. Then pinch the docking ring 310 and insert the docking ring 310 upward into the docking groove 110 opened at the bottom of the joint body 100, so that the inner side of the docking ring 310 is in close contact with the outer side of the first sealing ring 120;

[0034] Then pinch the pressing ring 200 to make the top of the docking pipe 210 face the bottom of the docking groove 110, and rotate the pressing ring 200 to rotatably connect the thread on the outer side of the docking pipe 210 with the internal thread groove opened on the side of the docking groove 110 away from the center of the circle, so that the docking pipe 210 rotates upward along the docking groove 110, and then install the pressing ring 200 below the joint body 100. At this time, the third sealing ring 220 adhesively bonded to the inner side of the docking pipe 210 is in close contact with the outer side of the docking ring 310, the inner side of the docking ring 310 is in close contact with the first sealing ring 120 adhesively bonded to the side of the docking groove 110 close to the center of the circle, and the bottom of the second sealing ring adhesively bonded to the top inside the docking pipe 210 is in close contact with the top of the docking groove 110, so as to greatly increase the friction force of the docking ring 310 inside the docking groove 110, and then greatly increase the anti-loosening effect of the hose body 300, and at the same time, it can also play an anti-leakage effect.

[0035] Example 2: Please refer to Figures 1 to 4, when maintenance is required for the joint body 100 and the compression ring 200, you can first pinch the compression ring 200 and rotate it in the reverse direction to make the docking pipe 210 rotate and disconnect from the docking groove 110. Then, pinch the hose body 300 and pull it downward to pull the docking ring 310 out of the inside of the docking groove 110, thereby removing the hose body 300 and the docking ring 310. Finally, pinch the compression ring 200 and keep it stationary, and pull the hose body 300 downward, so that the hose body 300 drives the docking ring 310 to move downward from the top of the docking pipe 210 until the docking ring 310 disengages from the bottom of the compression ring 200, thereby removing the compression ring 200. The final effect is to facilitate the quick installation and disassembly of the hose body 300, the compression ring 200, and the joint body 100, thereby improving the installation and disassembly efficiency, and then facilitating maintenance and replacement.

[0036] The above are only the preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included within the protection scope of the present invention.
