Technical Field

[0001] The utility model relates to a connecting mechanism and belongs to the technical field of pipeline connection. Background Art

[0002] Gas equipment is an important energy supply equipment in modern society. The safety and convenience of its connection mechanism are directly related to the operating efficiency of the equipment and the user experience. Bolt connection is a common connection method in gas equipment, with advantages such as simple structure and reliable connection. However, the traditional bolt connection mechanism has many inconveniences during the disassembly and assembly process.

[0003] In order to solve the above problems, a connecting mechanism is proposed. Utility Model Content

[0004] The purpose of the utility model is to provide a connecting mechanism to solve the problems raised in the above background technology.

[0005] In order to achieve the above-mentioned purpose, the utility model adopts the following technical solution: a connecting mechanism, comprising:

[0006] A connector 1, which is connected to the end of the tube body, and a plurality of protrusions are arranged on the outer wall of the connector 1;

[0007] The second connector is used to connect to the end of the gas hose. The second connector includes a sleeve portion, which is movably sleeved on the first connector. A buckle hole corresponding to the protrusion is provided on the side wall of the sleeve portion. When the sleeve portion is sleeved on the first connector, the protrusion and the buckle hole serve as a buckle assembly to fix the sleeve portion on the first connector.

[0008] Among them, outer bevels are formed on both sides of the protrusion, and inner bevels are formed on the two side walls of the snap-fit ​​hole. When joint one and joint two are rotated relative to each other, the guiding effect of the outer bevels and the inner bevels can make the protrusion and the snap-fit ​​hole rotate relative to each other, and the protrusion can be rotated out from the inside of the snap-fit ​​hole, thereby facilitating the removal of joint two from joint one.

[0009] Preferably, the outer surface of each protrusion is arranged in an inclined shape. When connecting, the inclined outer surface enables the protrusion to slide into the snap-on hole more easily, reducing the difficulty of connection, and each protrusion is provided with a clamping platform on an end face close to the tube body. When the protrusion is snapped into the snap-on hole, the clamping platform abuts against the side of the snap-on hole, which is used to limit the socket position of the sleeve part and the joint one, avoiding axial movement of the joint two and the joint one, and ensuring the reliability and safety of the connection mechanism during use.

[0010] Preferably, through hole 1 is opened inside connector 1, and through hole 2 is opened inside connector 2. When the sleeve portion is sleeved on connector 1, through hole 1 is connected with through hole 2, and the fluid passing through connector 1 can continue to enter the gas hose through connector 2 seamlessly.

[0011] Preferably, the sleeve portion is formed with an inner platform, and a sealing gasket is arranged on the opposite end surface of the connector one. When the sleeve portion is sleeved on the connector one, the sealing gasket is clamped between the inner platform and the end surface of the connector one.

[0012] Preferably, a plurality of pressure rings are provided on the surface of the inner platform. When the inner platform is butted against the end face of the joint one, the sealing gasket is clamped between the inner platform and the end face of the joint one, and the pressure ring is pressed on the sealing gasket, thereby increasing the sealing effect of the sealing gasket.

[0013] Preferably, a plug-in column is provided on the second connector, and a plurality of circles of barbed rings are provided on the outer wall of the plug-in column.

[0014] Preferably, a limiting groove is provided on the side wall of the first joint, and a clamping assembly which is clamped with the limiting groove is provided on the sleeve portion.

[0015] Preferably, the clamping assembly includes an elastic rod, the middle portion of the elastic rod is connected to the sleeve portion, a stopper is fixedly connected to the inner wall of one end of the elastic rod, and the stopper is movably connected to the inside of the limiting groove.

[0016] Preferably, the clamping assembly includes a bolt, which is meshedly connected to the sleeve portion, and a bolt end of the bolt penetrates the side wall of the sleeve portion and is movably inserted into the interior of the limiting groove.

[0017] Compared with existing technologies:

[0018] 1. The utility model can be movably sleeved on the joint through the sleeve part, and a buckle hole corresponding to the protrusion is opened on the side wall of the sleeve part. When the quick connector is connected to the joint, the protrusion will enter the buckle hole to achieve buckle fixation of the two.

[0019] 2. The utility model forms outer bevels on both sides of the protrusion, and inner bevels on the two side walls of the buckle hole, so that when the quick connector needs to be disassembled, it is only necessary to relatively rotate the quick connector. Due to the presence of the bevels, the protrusion can be smoothly rotated out from the inside of the buckle hole, thereby conveniently realizing the separation of the quick connector and the connector.

DETAILED DESCRIPTION

[0027] The present invention is described below with specific embodiments, but is not intended to be a limitation of the present invention.

[0028] Example 1

[0029] like Figure 1-Figure 6 As shown, in this embodiment, a connection mechanism is provided, including:

[0030] A connector 1, which is connected to the end of the tube body 3, and a plurality of protrusions 4 are arranged on the outer wall of the connector 1;

[0031] The connector 2 is used to connect to the end of the gas hose. The connector 2 includes a sleeve portion 201, which is movably sleeved on the connector 1. A buckle hole 202 corresponding to the protrusion 4 is provided on the side wall of the sleeve portion 201. When the sleeve portion 201 is sleeved on the connector 1, the protrusion 4 and the buckle hole 202 serve as a buckle assembly to fix the sleeve portion 201 on the connector 1.

[0032] Among them, both sides of the protrusion 4 are formed with outer bevels 402, and the two side walls of the buckle hole 202 are formed with inner bevels 203. When the joint 1 and the joint 2 are relatively rotated, the guiding effect of the outer bevels 402 and the inner bevels 203 can make the protrusion 4 and the buckle hole 202 rotate relative to each other, and the protrusion 4 can be rotated out from the inside of the buckle hole 202, and then the joint 2 2 is conveniently removed from the joint 1;

[0033] When the connector 2 and the connector 1 need to be separated, the working principle is as follows: the user needs to relatively rotate the connector 1 and the connector 2. Since the side edges of the protrusion 4 are designed with an outer bevel 402, and the side edges of the buckle hole 202 are designed with an inner bevel 203, the outer bevel 402 and the inner bevel 203 enable the protrusion 4 to smoothly slide out of the buckle hole 202 along the inner bevel 203 during the rotation process.

[0034] In addition, when separating connector 2 and connector 1, or connecting connector 2 and connector 1, the sleeve portion 201 is deformed by the action of the protrusion 4. Therefore, the sleeve portion 201 can be made of a deformable plastic material or metal material to adapt to the deformation caused by the thickness factor of the protrusion 4.

[0035] The outer surface of each protrusion 4 is arranged in an inclined shape. When connecting, the inclined outer surface enables the protrusion 4 to slide into the buckling hole 202 more easily, reducing the difficulty of connection, and each protrusion 4 is provided with a clamping platform 401 on an end face close to the tube body 3. When the protrusion 4 is buckled in the buckling hole 202, the clamping platform 401 abuts against the side of the buckling hole 202, which is used to limit the socket position of the sleeve portion 201 and the connector 1, avoiding axial movement of the connector 22 and the connector 1, and ensuring the reliability and safety of the connection mechanism during use.

[0036] A through hole 101 is provided inside the connector 1, and the through hole 101 is connected with the space inside the tube body, thereby allowing fluid (such as gas) to flow freely between the tube body and the connector 1. A through hole 207 is provided inside the connector 2. When the sleeve portion 201 is sleeved on the connector 1, the through hole 101 is connected with the through hole 207, and the fluid passing through the connector 1 can continue to enter the gas hose through the connector 22 seamlessly, ensuring the continuity and efficiency of the entire connection mechanism in fluid transmission.

[0037] like Figure 3 , Figure 4 As shown, in order to ensure the sealing when the joint 1 is connected to the joint 2, the sleeve part 201 is formed with an inner platform 204, and a sealing gasket 5 is arranged on the opposite end face of the joint 1. When the sleeve part 201 is sleeved on the joint 1, the sealing gasket 5 is clamped between the inner platform 204 and the end face of the joint 1, ensuring that the sealing gasket 5 can fit tightly on the end face of the joint 1 and is subjected to uniform pressure from the inner platform 204 and the end face of the joint 1. This pressure distribution not only helps to improve the sealing effect of the sealing gasket 5, but also prevents it from shifting or falling off during use.

[0038] like Figure 3 As shown, in order to further improve the sealing performance when connector 1 is connected to connector 2, a plurality of pressure rings 205 are provided on the surface of the inner platform 204. When the inner platform 204 is butted against the end face of connector 1, the sealing gasket 5 is clamped between the inner platform 204 and the end face of connector 1, and the pressure ring 205 is pressed on the sealing gasket 5, thereby increasing the sealing effect of the sealing gasket 5.

[0039] like Figure 1As shown, in order to be able to fix the gas hose on the connector 2, a plug-in column 206 is provided on the connector 2, and a plurality of circles of barb rings are provided on the outer wall of the plug-in column 206. When the gas hose is plugged on the plug-in column 206, the barb rings can fix the hose. Moreover, after the gas hose is plugged on the plug-in column 206, a clamp is clamped on the outer hoop of the hose to further fix it.

[0040] When the connector 2 is sleeved on the connector 1, in order to prevent the connector 2 and the connector 1 from deflecting and rotating relative to each other, a limiting groove 6 is provided on the side wall of the connector 1, and a clamping assembly clamped with the limiting groove 6 is provided on the sleeve portion 201.

[0041] Example 2

[0042] like Figure 1-Figure 5 As shown, on the basis of Example 1, in order to specifically prevent the joint 2 2 and the joint 1 from relative deflection and rotation, the clamping assembly of this embodiment includes an elastic rod 7, the middle part of the elastic rod 7 is connected to the sleeve part 201, and a stopper 8 is fixedly connected to the inner wall of one end of the elastic rod 7, and the stopper 8 is movably connected to the inside of the limiting groove 6. When the sleeve part 201 is sleeved on the joint 1, the stopper 8 is aligned with the mouth of the limiting groove 6. At this time, after the sleeve part 201 is sleeved on the joint 1, the stopper 8 is inside the limiting groove 6. At this time, the limiting effect of the stopper 8 and the limiting groove 6 can prevent the joint 2 2 and the joint 1 from relative deflection and rotation. In addition, when it is necessary to remove the joint 2 2 from the joint 1, press one end of the elastic rod 7 away from the stopper 8. At this time, after the elastic rod 7 is deflected, the stopper 8 is rotated out of the limiting groove 6. In this state, the relative rotation of the joint 2 2 and the joint 1 can be realized, thereby facilitating the separation of the joint 2 2 and the joint 1.

[0043] Example 3

[0044] like Figure 6 As shown, on the basis of Example 1, in order to specifically prevent the joint 2 2 and the joint 1 from relative deflection and rotation, the clamping assembly includes a bolt 9, the bolt 9 is meshedly connected to the sleeve portion 201, and the bolt end of the bolt 9 passes through the side wall of the sleeve portion 201 and is movably inserted into the interior of the limiting groove 6. After the sleeve portion 201 is sleeved on the joint 1, the bolt 9 is rotated, and the threaded end of the bolt 9 is inserted into the interior of the limiting groove 6. In this state, the limiting effect of the bolt 9 and the limiting groove 6 can prevent the joint 2 2 and the joint 1 from relative deflection and rotation. In addition, when it is necessary to remove the joint 2 2 from the joint 1, the bolt 9 is rotated to move the threaded end of the bolt 9 out of the interior of the limiting groove 6. In this state, the relative rotation of the joint 2 2 and the joint 1 can be realized, thereby facilitating the separation of the joint 2 2 and the joint 1.

[0045] Finally, it should be noted that the above embodiments are only used to illustrate rather than limit the technical solutions of the present invention. Although the present invention has been described in detail with reference to the above embodiments, those skilled in the art should understand that the present invention can still be modified or replaced by equivalents. Any modification or partial replacement that does not depart from the spirit and scope of the present invention should be included in the scope of the claims of the present invention.
