Description

Technical Field

[0001] The utility model relates to the technical field of hose connectors, in particular to a hose connector which is easy to disassemble. Background Art

[0002] Hose connector is a high-quality flexible pipe in modern industrial pipelines, which is mainly used to connect hoses or pipeline appliances.

[0003] Most of the existing hose connectors are connected to the hose only by threaded connection. The threaded connection between the hose connector and the hose is prone to thread slippage. After the thread slips, the hose connector and the hose are easily separated under the impact of water, which affects the use. In addition, the existing hose connector needs to be connected to the hose with the help of tools during installation and disassembly, which makes the installation and disassembly method more cumbersome. Utility Model Content

[0004] In order to overcome the disadvantages that when the thread of the hose connector and the hose is connected and slips, the hose connector and the hose are easily separated under the impact of water, which affects the use, and the existing hose connector needs tools during installation and removal, resulting in a cumbersome installation and removal method, the utility model provides a hose connector that is easy to disassemble.

[0005] The technical solution is as follows: A hose connector that is easy to disassemble, comprising a shell, connecting pipes are respectively provided at both ends of the shell, both ends of the shell are rotatably connected to fixing rings threadedly connected to the outer side surfaces of the connecting pipes, a thread groove is provided on the connecting pipe, and equidistantly distributed sliding grooves are provided on the connecting pipe, and the depth of the sliding grooves is the same as that of the thread grooves, and both sides of the shell are fixedly connected to limit plates for inserting into the inner sides of the sliding grooves.

[0006] Preferably, the outer structure of the connecting pipe is stepped, and the thread groove is opened on the side of the connecting pipe with a smaller outer diameter.

[0007] Preferably, the limiting plate is rotatably connected to a symmetrically distributed locking plate, a first hollow frame is embedded inside the limiting plate, a first slide is sealingly and slidingly connected inside the first hollow frame, and the first slide is rotatably connected to the locking plate, an annular airbag is provided inside the shell, and a plurality of delivery pipes are connected to the annular airbag, and the delivery pipes are inserted into the inner side of the limiting plate and connected to the first hollow frame.

[0008] Preferably, one end of the symmetrically distributed blocking plates that is close to each other is rotatably connected to the limit plate, and after the symmetrically distributed blocking plates swing, the two swing in different directions.

[0009] Preferably, the limiting plate is slidably connected to a support plate, a second hollow frame is embedded in the limiting plate, a second slide plate fixed to the support plate is sealingly and slidably connected in the second hollow frame, and the second hollow frame is connected to the conveying pipe.

[0010] Preferably, a locking groove and a rectangular groove are respectively provided at positions on the connecting pipe corresponding to the locking plate and the support plate, and the locking groove and the rectangular groove respectively cooperate with the locking plate and the support plate to fix the connecting pipe.

[0011] The beneficial effects of the utility model are as follows: the utility model connects the connecting pipe to the hose by means of a threaded connection, and moves the shell to insert the limit plate into the slide groove, so that the limit plate and the slide groove cooperate to clamp the connection between the connecting pipe and the hose, thereby preventing the connecting pipe from being rotated to separate from the hose, and at the same time rotating the fixing ring to fix it to the connecting pipe through a threaded connection, thereby completing the fixation of the shell and the connecting pipe.

DETAILED DESCRIPTION

[0020] The utility model is further described below in conjunction with the accompanying drawings and embodiments.

[0021] like Figure 1-Figure 7 The hose connector shown in the figure is easy to disassemble, comprising a shell 1, with connecting pipes 2 provided at the upper and lower ends of the shell 1 respectively, the connecting pipes 2 and the shell 1 are in contact and fit, the outer structure of the connecting pipe 2 is stepped, the upper and lower ends of the shell 1 are rotatably connected with fixing rings 3 threadedly connected to the outer side of the connecting pipe 2, a threaded groove 4 is provided on the side with a smaller outer diameter of the connecting pipe 2, the connecting pipe 2 is provided with four circumferentially equidistantly distributed slide grooves 5, and the slide grooves 5 have the same depth as the threaded grooves 4, the upper and lower sides of the shell 1 are fixedly connected with limit plates 6 for inserting into the inner side of the slide grooves 5, the connecting pipe 2 is connected to the hose by threaded connection, and then the limiting plate 6 is inserted into the slide groove 5 by moving the shell 1, and the connection between the connecting pipe 2 and the hose can be positioned through the cooperation of the limiting plate 6 and the slide groove 5 to avoid rotating the connecting pipe 2 to separate it from the hose.

[0022] Two symmetrically distributed card plates 7 are rotatably connected to the limiting plate 6. One end of the two symmetrically distributed card plates 7 is close to the limiting plate 6. After the two symmetrically distributed card plates 7 swing, the two swing in different directions. The different swing directions of the two can strengthen the fixed relationship between the connecting pipe 2 and the shell 1, and prevent the threaded buckle from causing relative slip and separation between the shell 1 and the connecting pipe 2, thereby affecting the use. A first hollow frame 8 is embedded in the limiting plate 6, and a first slide plate 9 is sealed and slidably connected in the first hollow frame 8, and the first slide plate 9 is rotatably connected to the card plate 7. An annular airbag 10 is provided inside the shell 1, and a conveying pipe 11 is connected to the annular airbag 10, which is inserted into the inner side of the limiting plate 6 and is connected to the first hollow frame 8. A support plate 12 is slidably connected to the limiting plate 6, and a second hollow frame 13 is embedded in the limiting plate 6. The second hollow frame 13 is sealed and slidably connected to the support plate 12 is fixedly connected to the second slide plate 14, and the second hollow frame 13 is connected to the delivery pipe 11. The positions corresponding to the positioning plate 7 and the support plate 12 on the connecting pipe 2 are respectively provided with a positioning groove 15 and a rectangular groove 16. The positioning groove 15 and the rectangular groove 16 cooperate with the positioning plate 7 and the support plate 12 respectively, and are used to fix the connecting pipe 2. The water pressure can compress the annular airbag 10 and transport the gas inside it to the first hollow frame 8 and the second hollow frame 13 through the delivery pipe 11, and respectively push the first slide plate 9 and the second slide plate 14 to move, so that the two positioning plates 7 swing with the rotation connection with the limiting plate 6 as the rotation point, and then snap into the corresponding positioning groove 15, and at the same time, the support plate 12 is moved and snapped into the rectangular groove 16 (when the annular airbag 10 is not squeezed, the positioning plate 7 and the support plate 12 are respectively in a vertically flush state with the side of the limiting plate 6), so that the fixed relationship between the shell 1 and the connecting pipe 2 can be further strengthened.

[0023] When in use, the user first connects the connecting pipe 2 to the hose by means of a threaded connection, and then moves the shell 1 to insert the limit plate 6 into the slide groove 5. At this time, the limit plate 6 can block the threads on the hose (the threads on the hose are not continuous, but intermittent). Through the cooperation of the limit plate 6 and the slide groove 5, the connection between the connecting pipe 2 and the hose can be locked to avoid rotating the connecting pipe 2 to separate it from the hose. In this process, the user rotates the fixing ring 3 to fix it to the connecting pipe 2 by a threaded connection, completing the fixation of the connecting pipe 2 and the shell 1. Then the user connects another hose or directly connects the instrument pipe to be used in the above manner.

[0024] During use, there will be water pressure in the shell 1, and the water pressure can compress the annular airbag 10 and transport the gas inside it to the first hollow frame 8 and the second hollow frame 13 through the delivery pipe 11, respectively pushing the first slide plate 9 and the second slide plate 14 to move, so that the locking plate 7 and the support plate 12 are respectively locked into the corresponding locking groove 15 and the rectangular groove 16, thereby further strengthening the fixing relationship between the shell 1 and the connecting pipe 2, and the greater the water pressure, the more firmly the fixing between the shell 1 and the connecting pipe 2 is made. By symmetrically arranged locking plates 7 with different swing directions, the fixing relationship between the connecting pipe 2 and the shell 1 can be strengthened, and the threaded buckle can be prevented from causing relative slip and separation between the shell 1 and the connecting pipe 2, thereby affecting use.

[0025] Although the utility model is described in detail with reference to the above embodiments, it is obvious to those skilled in the art through this disclosure that various changes or modifications can be made to the utility model without departing from the principle and spirit of the utility model defined by the claims. Therefore, the detailed description of the embodiments of the present disclosure is only used to explain, not to limit the utility model, but the scope of protection is limited by the content of the claims.
