Description

Technical Field

[0001] This utility model relates to a telescopic column interlocking sealing fluid connector. Background Technology

[0002] A fluid connector is a specially designed connection device intended to ensure that fluids can flow smoothly through pipes without being obstructed by the presence of the fluid connector.

[0003] However, an existing type of sealed fluid connector has the following drawbacks due to the lack of a telescopic pin interlocking structure:

[0004] The ability to open the flow channel by operating the handle when the two fluid connectors are not connected increases the risk of accidental handle operation.

[0005] Even when two fluid connectors are connected and the flow channels are open, the two fluid connectors can still be rotated apart, causing fluid leakage. Summary of the Invention

[0006] The purpose of this utility model is to provide a telescopic column interlocking sealing fluid connector, including a valve body, a handle, and an interlocking assembly. The front end of the valve body is a locking surface, and the valve body is provided with a valve ball assembly for rotating and controlling the opening and closing of the flow channel of the valve body. The handle is disposed on the valve body and connected to the valve ball assembly. The interlocking assembly includes a telescopic locking rod, a ball bearing, and a first spring. The valve body is provided with a mounting cavity and a locking hole. The telescopic locking rod is slidably disposed in the mounting cavity along the axial direction. The front end of the telescopic locking rod passes through the locking surface and extends outward. The front end is a truncated cone head, the arc surface of which is adapted to the lock hole. The rear end of the telescopic locking rod is connected to a first spring. The telescopic locking rod is provided with a positioning groove group for axial limiting of the telescopic locking rod. The valve body is provided with a mounting through hole, which connects to the mounting cavity. The ball is disposed on the mounting through hole, which corresponds to the positioning groove group, and part of the ball is located within the positioning groove group. The handle is provided with a ball-embedded groove, which corresponds to the closed position of the handle, and part of the ball-embedded groove is adapted to the ball.

[0007] Preferably, the positioning groove group includes a deep groove and a shallow groove arranged axially. The deep groove has a left limiting slope on the side facing the truncated cone head, a transition slope is provided between the deep groove and the shallow groove, and the shallow groove has a right limiting slope on the side facing the spring.

[0008] Preferably, there are two valve bodies arranged symmetrically on the left and right. The locking surface of each valve body is provided with a snap-fit ​​part, and the rear end of each valve body is provided with a pipe connector. The two valve bodies are detachably connected through the snap-fit ​​part, and the arc surface of the truncated cone head is inserted into the locking hole of the opposite valve body.

[0009] Preferably, the locking surface edge of the valve body is provided with a first sealing ring, and the flow channel edge of the valve ball assembly is provided with a second sealing ring.

[0010] Preferably, a locking mechanism is provided between the valve body and the handle. The locking mechanism includes a locking bead, a second spring, and a button. The locking bead is slidably connected to the handle and is disposed on the handle. The valve body also has a first locking groove and a second locking groove, which correspond to the open and closed positions of the handle, respectively.

[0018] The specific embodiments of this utility model will be further described below with reference to the accompanying drawings and examples. The following examples are only used to more clearly illustrate the technical solution of this utility model and should not be construed as limiting the scope of protection of this utility model.

[0019] The specific technical solution of this utility model is as follows:

[0020] like Figure 1 As shown, a telescopic column interlocking sealing fluid connector includes a valve body 1, a handle 2, and an interlocking assembly 3. The front end of the valve body 1 is a locking surface 5. The valve body 1 has a valve ball assembly 4 inside for rotating to control the flow path opening and closing. The handle 2 is mounted on the valve body 1 and connected to the valve ball assembly 4. The interlocking assembly 3 includes a telescopic locking rod 31, a ball bearing 32, and a first spring 33. The valve body 1 has a mounting cavity 6 and a locking hole 7. The telescopic locking rod 31 is slidably disposed within the mounting cavity 6 along its axial direction. The front end of the telescopic locking rod 31 penetrates the locking surface 5 and extends outward. The front end of the telescopic locking rod 31 is a frustum-shaped head 311. The arc surface 312 of the truncated cone head 311 is adapted to the lock hole 7. The rear end of the telescopic locking rod 31 is connected to a first spring 33. The telescopic locking rod 31 is provided with a positioning groove group 10 for axially limiting the telescopic locking rod 31. The valve body 1 is provided with a mounting through hole 8, which connects to the mounting cavity 6. The ball bearing 32 is disposed on the mounting through hole 8, which corresponds to the positioning groove group 10. A portion of the ball bearing 32 is located within the positioning groove group 10. The handle 2 is provided with a ball-embedded groove 9, which corresponds to the closed position of the handle 2. A portion of the ball-embedded groove 9 is adapted to the ball bearing 32.

[0021] like Figure 5 As shown, the above-mentioned positioning groove group 10 includes a deep groove 102 and a shallow groove 101 connected axially. The deep groove 102 has a left limiting slope 103 on the side facing the frustum head 311. A transition slope 104 is provided between the deep groove 102 and the shallow groove 101. The shallow groove 101 has a right limiting slope 105 on the side facing the first spring 33.

[0022] Two valve bodies 1 are provided, and the two valve bodies 1 are arranged symmetrically from left to right. The locking surface 5 of the valve body 1 is provided with a snap-fit ​​part 51, and the rear end of the valve body 1 is provided with a pipe connector 52. The two valve bodies 1 are detachably connected through the snap-fit ​​part 51. The arc surface 312 of the truncated cone head 311 is inserted into the locking hole 7 of the opposite valve body 1.

[0023] like Figure 1 As shown, the locking surface 5 of the valve body 1 is provided with a first sealing ring 11, and the flow channel opening of the valve ball assembly 4 is provided with a second sealing ring 12.

[0024] like Figure 6As shown, a locking mechanism 13 is provided between the valve body 1 and the handle 2. The locking mechanism 13 includes a locking bead 131, a second spring 134, and a button 135. The locking bead 131 is slidably connected to the handle 2 and is disposed on the handle 2. The valve body 1 also has a first locking groove 132 and a second locking groove 133. The first locking groove 132 and the second locking groove 133 correspond to the open and closed positions of the handle 2, respectively. The first locking groove 132 and the second locking groove 133 cooperate with the locking bead 131. The button 135 is slidably mounted on the handle 2. The button 135 is provided with a clearance groove 136 for accommodating the locking bead 131. The two ends of the second spring 134 are respectively connected to the button 135 and the handle 2. The second spring 134 is located inside the handle 2.

[0025] Specifically, the second spring 134 elastically drives the button 135 to move, causing the end of the button 135 to extend out of the handle 2. At this time, the clearance groove 136 is misaligned with the locking bead 131, causing the button 2 to drive the locking bead 131 to move downward, thereby allowing the locking bead 131 to extend into the first locking groove 132 or the second locking groove 133, locking the handle 2. When it is necessary to rotate the handle 2, the operator needs to press the button 135 to align the clearance groove 136 with the locking bead 131. Then, rotating the handle 2 will allow the locking bead 131 to move upward into the clearance groove 136. At this time, the handle 2 can be rotated to change the open or closed state, further avoiding the risk of accidental activation.

[0026] When using: such as Figure 2 As shown, when the two valve bodies 1 are not connected, the telescopic locking rod 31 protrudes from the locking surface 2 of the valve body 1, and the ball 32 is stuck between the mounting through hole 8 of the valve body 1, the ball groove 9 of the handle 2 and the shallow groove 101 of the telescopic locking rod 31. The ball 32 locks the handle 2 in the closed position to prevent accidental contact with the handle 2 and fluid leakage. At the same time, the ball 32 prevents the telescopic locking rod 31 from coming out of the mounting cavity 6.

[0027] like Figure 3 As shown, when the two valve bodies 1 are pressed together, the telescopic locking rod 31 is pushed into the mounting cavity 6 of the valve body 1, and the first spring 33 is deformed by force. When the two valve bodies 1 are rotated to make the locking part 51 lock into place, the truncated cone head 311 of the telescopic locking rod 31 is aligned with the locking hole 7 of the other valve body 1. The rebound force of the first spring 33 causes the arc surface 312 of the truncated cone head 311 to be inserted into the locking hole 7. The deep groove 102 on the telescopic locking rod 31 moves to the corresponding position of the ball 32, and the handle 2 is unlocked.

[0028] like Figure 4As shown, when the handle 2 is moved to the open position, the flow channel is opened, the ball groove 9 on the handle 2 is misaligned with the position of the ball 32, the handle 2 presses the ball 32 downward, and the ball 32 is pushed into the mounting through hole 8 of the valve body 1 and the deep groove 102 of the telescopic locking rod 31, so that the telescopic locking rod 31 is axially limited. Since the arc surface 312 of the truncated cone head 311 of the telescopic locking rod 31 is located in the locking hole 7 of another valve body 1, the locking connection between the two valve bodies 1 is completed, preventing fluid leakage between the two fluid connectors.

[0029] like Figure 2 As shown, the handle 2 is then moved to the closed position, the flow channel is closed, and the ball groove 9 on the handle 2 moves to the corresponding position of the ball 32. Since the truncated cone head 311 of the telescopic locking rod 31 has an arc surface 312, during the process of the two valve bodies 1 disengaging from the locking part 51 by rotation, the arc surface 312 of the truncated cone head 311 is squeezed. The truncated cone head 311 drives the telescopic locking rod 31 into the mounting cavity 6. The first spring 33 is deformed by force, and the left limiting inclined surface 103 of the telescopic locking rod 31 squeezes the ball 32 upward. The ball 32 moves upward from the deep groove 102 to between the mounting through hole 8 of the valve body 1 and the ball groove 9 of the handle 2, locking the handle 2. When the two valve bodies 1 are completely separated, the rebound force of the first spring 33 causes the truncated cone head 311 of the telescopic locking rod 31 to protrude from the locking surface 5 of the valve body 1, and the shallow groove 101 of the telescopic locking rod 31 moves to the corresponding position of the ball 32.

[0030] The above description is only a preferred embodiment of the present utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the technical principles of the present utility model, and these improvements and modifications should also be considered within the protection scope of the present utility model.
