Description

Technical Field

[0001] The present application relates to the field of pipe joints, and in particular to a hose joint that is easy to install. Background Art

[0002] Pipe fittings are commonly used components in hydraulic systems, mainly used to connect two or more pipes.

[0003] In the related art, a Chinese patent with the patent number CN201428883Y discloses a hose-to-hose connection joint, which includes a joint and a locking nut threadedly connected to both ends of the joint, and a conical tube for connecting with the hose is coaxially arranged at both ends of the joint. When in use, the hose is sleeved on the conical tube, and then the locking nut is tightened and fixed on the joint, and the locking nut presses the hose on the joint, thereby realizing the connection of the two hoses.

[0004] In actual use, it is found that when the hose is put on the conical tube, the end of the hose needs to be expanded to make the hose produce elastic deformation and fit on the conical tube in a trumpet shape. In order to improve the overall practical life and strength of some hoses, a reinforced layer structure is set on the side wall of the hose, which makes the hose unable to expand radially, resulting in the inability to use the above structure for connection, which needs to be improved. Summary of the invention

[0005] In order to facilitate the connection of a hose, the present application provides a hose connector that is easy to install.

[0006] The present application provides a hose connector that is easy to install and adopts the following technical solution:

[0007] A hose connector that is easy to install, comprises a connector and a connecting sleeve installed at both ends of the connector, and also comprises a clamp coaxially arranged in the connecting sleeve, wherein the clamp is arranged as an elastic open ring; connecting pipes adapted to the hose are coaxially fixed at both ends of the connector; connecting threads that match each other are arranged on the outer wall of the connector and the inner wall of the connecting sleeve, and when the connector is installed on the connecting sleeve, an installation gap for installing the hose is reserved between the clamp and the connecting pipe; mutually matching slopes are arranged at positions on the connector corresponding to the clamp, and when the connecting sleeve is tightened on the connector, the slope on the connector presses the clamp radially inward.

[0008] By adopting the above technical solution, the connecting pipes are coaxially fixed at both ends of the connecting head. When connecting the hose, it is only necessary to put the hose sleeve on the two connecting pipes, place the end of the hose in the installation gap, and then tighten the connecting sleeve on the connecting head through the connecting thread; in the process of tightening the connecting sleeve, the clamp moves toward the middle of the connecting head driven by the connecting sleeve. Since the clamp is an open ring structure, when the clamp moves, the clamp will elastically shrink inward in the radial direction under the action of the slope to squeeze the hose, thereby pressing the hose against the connecting pipe to achieve a sealed connection; in the process of the clamp pressing the hose, the clamp continues to move toward the middle of the connecting head, and the clamp will form a tendency to push the hose toward the middle of the connecting head, thereby making the end of the hose press against the connecting head, further improving the sealing effect of the hose and the connecting head.

[0009] Optionally, a limiting sleeve is coaxially fixed on the outer side of the connector at one end close to the clamp, and the slope is located at one end of the limiting sleeve close to the clamp; a sealing groove is formed between the limiting sleeve and the connecting pipe, and the end of the hose is inserted into the sealing groove.

[0010] By adopting the above technical solution, a limit sleeve is provided, and a slope is provided at the end of the limit sleeve. When the connecting sleeve is tightened onto the connecting head, after the clamp abuts against the slope, the clamp can gradually shrink and be inserted into the sealing groove, thereby improving the compression and sealing performance of the hose. As the clamp is continuously inserted, the clamp will push the end of the hose to press against the bottom of the sealing groove, thereby improving the sealing of the hose.

[0011] Optionally, a sealing ring is installed in the sealing groove.

[0012] By adopting the above technical solution, a sealing ring is installed in the sealing groove. During the process of tightening the connecting sleeve, the clamp pushes the hose to the bottom of the sealing groove, and the end of the hose is pressed against the sealing ring, further improving the overall sealing effect.

[0013] Optionally, a first elastic groove is formed on the side wall of the clamp at one end close to the slope surface, and a plurality of first elastic grooves are distributed along the circumferential direction of the clamp.

[0014] By adopting the above technical solution, a first elastic groove is opened at one end of the clamp close to the slope, so that the end of the clamp close to the slope has a certain elasticity. During the process of tightening the connecting sleeve, the end of the clamp close to the slope can be elastically tightened.

[0015] Optionally, a clamping ring is coaxially fixed on the inner wall of the connecting sleeve at a position corresponding to the clamping hoop, and a matching clamping groove is coaxially provided on the outer wall of the clamping hoop at a position corresponding to the clamping ring.

[0016] By adopting the above technical solution, a clamping ring is arranged on the inner wall of the connecting sleeve, and a clamping groove is opened on the outer wall of the clamp. During assembly, it is only necessary to insert the end of the clamp with the slope into the clamping ring. The clamp will shrink inwardly under the action of the slope until the clamping ring is inserted into the clamping groove, which facilitates assembly.

[0017] Optionally, a second elastic groove is formed at one end of the clamp away from the slope, and a plurality of the second elastic grooves are distributed along the circumferential direction of the clamp.

[0018] By adopting the above technical solution and opening a second elastic groove on the clamp, the entire clamp can have the ability to elastically shrink, thereby preventing the clamp from being over-deformed and causing failure during the process of installing the clamp into the connecting sleeve.

[0019] Optionally, teeth are provided on the inner side wall of the clamp at one end close to the slope surface.

[0020] By adopting the above technical solution, the teeth can increase the friction between the clamp and the hose, so that when tightening the connecting sleeve, the clamp can push the hose inward, thereby improving the sealing performance.

[0021] Optionally, a twisting portion is coaxially arranged in the middle of the connector, and the twisting portion is arranged to be a polygonal column structure.

[0022] By adopting the above technical solution, a screwing part is provided on the connecting head, and when tightening or disassembling the connecting sleeve, the screwing part on the connecting head can be screwed by a tool, which is convenient for use.

[0023] In summary, the present application includes at least one of the following beneficial technical effects:

[0024] 1. By coaxially fixing the connecting pipes at both ends of the connector, when connecting the hose, it is only necessary to put the hose sleeve on the two connecting pipes, place the ends of the hose in the installation gap, and then tighten the connecting sleeve on the connector through the connecting thread. In the process of tightening the connecting sleeve, the clamp moves toward the middle of the connector under the drive of the connecting sleeve. When the clamp moves, the clamp will contract radially inward under the action of the slope to squeeze the hose, thereby pressing the hose against the connecting pipe to achieve a sealed connection. In the process of the clamp pressing the hose, the clamp continues to move toward the middle of the connector, and the clamp will form a trend of pushing the hose toward the middle of the connector, so that the end of the hose is pressed against the connector, further improving the sealing effect of the hose and the connector;

[0025] 2. By providing a limit sleeve and providing a slope surface at the end of the limit sleeve, when the connecting sleeve is tightened onto the connecting head, after the clamp abuts against the slope surface, the clamp can be gradually contracted and inserted into the sealing groove, thereby improving the compression and sealing performance of the hose, and as the clamp is continuously inserted, the clamp will push the end of the hose to the bottom of the sealing groove, thereby improving the sealing of the hose;

[0026] 3. By installing the sealing ring in the sealing groove, when tightening the connecting sleeve, the clamp pushes the hose to the bottom of the sealing groove, and the end of the hose will be pressed against the sealing ring, further improving the overall sealing effect.

[0032] The following is combined with Figure 1-4 This application is described in further detail.

[0033] The present application embodiment discloses a hose connector which is easy to install. Figure 1 and Figure 2 , including a connector 1, a connector sleeve 2 and a clamp 3. Connecting pipes 11 are coaxially formed at both ends of the connector 1. The connecting pipes 11 are cylindrical tubes, which are convenient for installing the hose 6. Two clamps 3 are provided corresponding to the connecting sleeves 2. The clamps 3 are set as open ring structures and are installed on the inner side of the connecting sleeve 2. Connecting threads 12 are integrally formed on both ends of the outer wall of the connector 1 and the inner wall of the connecting sleeve 2. The connecting threads 12 are threads with the same rotation direction. The connecting sleeve 2 is tightened and installed on the connector 1 through the connecting threads 12. When in use, the two hoses 6 to be connected are respectively sleeved on the connecting pipes 11 at both ends, and then the connecting sleeve 2 is tightened and fixed on the connector 1. After the connecting sleeve 2 is tightened and fixed, the clamp 3 will seal and fix the hose 6 on the connecting pipe 11.

[0034] Reference Figure 2 and Figure 3 A limiting sleeve 13 is coaxially integrally formed on the outer side of the connector 1. Two limiting sleeves 13 are provided at positions corresponding to the clamp 3. A sealing groove 15 is formed between the limiting sleeve 13 and the connecting pipe 11. The clamp 3 is an elastic cylindrical sleeve structure. The clamp 3 is detachably connected to the inner side of the connecting sleeve 2. An installation gap 4 is formed between the clamp 3 and the connecting pipe 11. After installation, the hose 6 is inserted into the installation gap 4. A slope 14 is formed at one end where the clamp 3 and the limiting sleeve 13 are close to each other. When the hose 6 is connected, the end of the hose 6 is inserted into the sealing groove 15. During the process of tightening the connecting sleeve 2, the slope 14 will tighten the end of the clamp 3 inward, so that the clamp 3 presses and seals the hose 6.

[0035] At one end of the clamp 3 close to the slope 14, teeth 31 protruding inward are arranged on the inner side wall of the clamp 3, and a sealing ring 5 is installed at the bottom of the sealing groove 15. In the process of tightening the connecting sleeve 2, the clamp 3 will follow the connecting sleeve 2 to move toward the middle of the connector 1. In the process of moving the clamp 3, the end of the clamp 3 will be squeezed inward under the action of the slope 14, so that the teeth 31 are pressed tightly against the hose 6, and as the clamp 3 continues to move inward, the clamp 3 will drive the hose 6 to move toward the middle of the connector 1, so that the end of the hose 6 presses the sealing ring 5, thereby effectively improving the sealing of the hose 6.

[0036] Reference Figure 3 and Figure 4 The first elastic groove 32 and the second elastic groove 33 are respectively provided at both ends of the clamp 3. The first elastic groove 32 is located at the end of the clamp 3 close to the slope 14. The first elastic groove 32 and the second elastic groove 33 are parallel to the axial direction of the clamp 3. The first elastic groove 32 and the second elastic groove 33 are evenly distributed in multiple paths along the circumferential direction of the clamp 3 and are spaced apart from each other, so that the clamp 3 as a whole can produce elastic deformation in the radial direction. A clamp ring 21 is coaxially provided on the inner side wall of the connecting sleeve 2 at the position corresponding to the clamp 3. A clamping groove 34 is coaxially provided on the outer side wall of the clamp 3 at the end away from the slope 14. When installing the clamp 3, the end of the clamp 3 with the slope 14 is inserted from the clamp ring 21. Under the action of the clamp ring 21, the clamp 3 elastically contracts in the radial direction until the clamp ring 21 is inserted into the clamping groove 34, thereby realizing the connection between the clamp 3 and the connecting sleeve 2.

[0037] A hexagonal prism-shaped screwing portion 16 is coaxially integrally formed on the middle outer wall of the connector 1. During installation or removal, a screwing force can be applied to the screwing portion 16 by a tool to facilitate tightening or loosening the connector 1 and the connecting sleeve 2.

[0038] The implementation principle of a hose connector that is easy to install disclosed in an embodiment of the present application is as follows: by arranging the clamp 3 on the connecting sleeve 2, and arranging a limiting sleeve 13 on the outer side of the connecting sleeve 2 corresponding to the clamp 3, when connecting the hose 6, during the process of tightening the connecting sleeve 2, the slope 14 on the limiting sleeve 13 will press and shrink the clamp 3 inward, so that the clamp 3 presses the hose 6 against the connecting sleeve 2 for sealing, and the connecting sleeve 2 is further tightened, the clamp 3 will drive the hose 6 to move inward, so that the end of the hose 6 is pressed against the sealing ring 5, thereby achieving double sealing, which can effectively improve the connection sealing of the hose 6.

[0039] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
