Description

Technical Field

[0001] The utility model belongs to the field of air tightness detection of pipe joints, in particular to an air tightness detection device for micro-cable micro-tube quick-plug connectors. Background Art

[0002] Optical fibers used in communication projects are easily damaged during construction and use, so they need to be protected. The optical fibers are placed in microcables. Microcables have less protective layer materials than traditional optical cables and must be laid in the pipeline in batches to reduce the number of microcable cores in the early stage. Since the construction and use process is generally in an outdoor environment, the microcable must be able to resist external pollution. Not only must the microcable be placed in a microtube, but also, when the two ends of the microtube are connected to other microtubes, quick-plug connectors with good sealing performance must be used. At present, air tightness is mostly tested.

[0003] An unlocking piece is provided inside the microcable microduct quick-plug connector. The microduct can be separated from the quick-plug connector by pressing the unlocking piece with external force, which is convenient for users to protect, repair and extend the microcable in the microduct.

[0004] At present, the existing technologies mostly inflate the ventilation tube and the quick-connector by plugging them together, and detect the sealing performance based on whether the air pressure inside the quick-connector changes within a certain period of time; however, after the ventilation tube and the quick-connector are plugged together, an external force is required to manually press the unlocking piece of the quick-connector to separate the micro-tube from the quick-connector, which greatly reduces the detection efficiency, and the micro-cable micro-tube quick-connector is damaged due to the uneven pressure applied by the hand.

[0005] Micro-cable and micro-tube quick-connectors are generally divided into single-end quick-connectors (which play the role of plug sealing) and double-end quick-connectors (which play the role of connectors). Different detection devices are required for the above two products. The existing detection devices are complex in structure and too costly. Utility Model Content

[0006] The utility model is dedicated to solving the technical problem that after the above-mentioned micro-cable micro-tube quick-plug connector is detected, it is necessary to manually press the quick-plug connector unlocking piece to realize the separation of the micro-tube and the quick-plug connector. The utility model can detect different types of quick-plug connectors to achieve multiple uses of one machine.

[0007] According to an embodiment of the utility model, a micro-cable micro-tube quick-plug connector air tightness detection device includes a first frame and a first driving device fixed to the outside of the first frame. A ventilation pipe is inserted on the first frame, and the ventilation pipe is connected to an air intake device. An air pressure sensor is also independently provided on the ventilation pipe. A first movable baffle is provided at the driving end of the first driving device. The first movable baffle is inserted on the ventilation pipe. The first movable baffle can be horizontally moved under the drive of the first driving device to contact the unlocking piece of the quick-plug connector and press it to unlock and disengage.

[0008] Preferably, the micro-cable micro-tube quick-plug connector air tightness detection device also includes a second frame arranged opposite to the first frame, a second driving device is provided on the outside of the second frame, a driving end of the second driving device is connected to a quick-plug plug for being inserted into the other end of the connector, a second movable baffle is passed through the quick-plug plug, and a fixed slide rod is also provided between the first frame and the second frame, and a limit baffle is fixed on the fixed slide rod. The second driving device resets and drives the quick-plug connector inserted at the driving end to move toward the second frame together, and the second movable baffle no longer moves after contacting the limit baffle until it conflicts with the unlocking piece at the other end of the connector and is pressed against the second movable baffle to unlock and disengage.

[0009] Preferably, two ends of the second movable baffle are connected to return springs, the other end of the return spring is connected to the second stand, and the second movable baffle can move toward the second stand under the action of the return spring.

[0010] Preferably, a plurality of vent pipes are provided, and the quick-insert plugs correspond one to one to the vent pipes.

[0011] Preferably, the lower portion between the first rack and the second rack is arranged as an inclined surface.

[0012] Preferably, the system further comprises a control device, the air pressure sensor being electrically connected to the control device, and an indicating device connected to the control device and matching the air pressure sensor one-to-one for indicating the air pressure state.

[0013] The beneficial effects of the utility model are:

[0014] 1. Driven by the first driving device, the first movable baffle can be horizontally moved to contact the unlocking piece of the quick-plug connector and press it to unlock and disengage, so as to realize the unlocking and disengagement of the single-head micro-cable micro-tube quick-plug connector and the vent pipe, and the unlocking piece is evenly squeezed by the movable baffle to reduce the damage to the unlocking piece caused by uneven pressure of the hand.

[0015] 2. Further add a second stand, a second drive device, a second movable baffle, a fixed slide rod, a limit baffle, etc. to unlock and disengage the other end of the micro-cable micro-tube quick-plug connector from the ventilation pipe, so as to realize rapid detection of the double-head micro-cable micro-tube quick-plug connector.

[0016] 3. Through the reset spring structure, when the second movable baffle is reset to the limit baffle, the second movable baffle is not easy to slide down under the pulling force of the reset spring, thereby improving the positive contact and extrusion between the second movable baffle and the quick-plug connector, and realizing the contact and pressing of the unlocking piece at the other end of the quick-plug connector and the second movable baffle to unlock and disengage.

[0017] 4. By setting up multiple ventilation pipes and quick-insert plugs, multiple inspections can be achieved at one time, thus improving inspection efficiency.

[0027] The present invention will now be further described in detail in conjunction with the accompanying drawings. These drawings are simplified schematic diagrams that only illustrate the basic structure of the present invention in a schematic manner, and therefore only show the components related to the present invention.

[0028] Example 1

[0029] refer to Figure 1 This embodiment can be used to detect single-ended micro-cable micro-duct quick-plug connectors, which have one end that is quick-plugged and the other end that is closed.

[0030] The air tightness detection device for micro-cable micro-tube quick-plug connectors comprises a first frame 1 and a first driving device 3 fixed on the outside of the first frame 1. A vent pipe 4 is inserted on the first frame 1. Before the inflation detection, the micro-cable micro-tube quick-plug connector is first inserted into the vent pipe 4 to simulate the quick-plug connection of the micro-cable micro-tube. The vent pipe 4 is connected to an air intake device 5, which controls the inflation of air into the quick-plug connector through the vent pipe 4 and the solenoid valve 13. An air pressure sensor 14 is also independently provided on the vent pipe 4. After quantitative inflation, the solenoid valve 13 is automatically closed. The pressure sensor 14 detects whether the internal pressure of the quick-plug connector changes to detect its air tightness. A first movable baffle 6 is provided at the driving end of the first drive device 3. The first movable baffle 6 is inserted into the vent pipe 4. After the air pressure detection is completed, the first movable baffle 6 can move horizontally under the drive of the first drive device 3. At this time, the first movable baffle 6 contacts the unlocking piece of the quick-plug connector and presses it. After the force is applied, the unlocking piece is unlocked from the vent pipe, and the first movable baffle 6 continues to move horizontally under the drive of the first drive device 3, and the quick-plug connector is detached from the vent pipe.

[0031] In this embodiment, a control device is also included, the air pressure sensor 14 is electrically connected to the control device, and an indicating device connected to the control device and matched with the air pressure sensor 14 for indicating the air pressure state is also included. When in use, the quick-plug connector to be tested is inserted into the vent pipe 4, and then the test is started. During the test, the solenoid valve 13 is opened for air pressure filling, and then the solenoid valve 13 is closed, and the air pressure sensor 14 detects the air pressure in the closed pipeline. If the value of the air pressure detection device changes significantly, the control device issues a prompt through the indicating device.

[0032] Example 2

[0033] refer to Figure 2 , Figure 3 , Figure 4 and Figure 5 This embodiment is an improvement based on Embodiment 1. On the basis of Embodiment 1, a double-ended micro-cable micro-tube quick-connect connector is tested.

[0034] The air tightness detection device for the micro-cable micro-tube quick-plug connector also includes a second stand 2 arranged opposite to the first stand 1, a second driving device 7 is arranged on the outer side of the second stand 2, and a driving end of the second driving device 7 is connected to a quick-plug plug 8 for being inserted into the other end of the quick-plug connector. One end of the quick-plug connector is first inserted into the ventilation pipe 4 on the first stand 1. At this time, the quick-plug plug 8 at the driving end of the second driving device 7 moves horizontally until the quick-plug plug is inserted and connected with the quick-plug connector, simulating the quick-plug connection at both ends of the micro-cable micro-tube. At this time, the air intake device 5 controls the inflation of the quick-plug connector through the ventilation pipe 4 and the solenoid valve 13. After quantitative inflation, the solenoid valve 13 is automatically closed. The air pressure sensor 14 detects whether the internal pressure of the double-headed micro-cable micro-tube quick-plug connector changes to detect its air tightness; after the air pressure detection is completed, the first movable baffle 6 can be moved horizontally under the drive of the first driving device 3. At this time, the first movable baffle 6 contacts one end of the double-headed micro-cable micro-tube quick-plug connector. The end unlocking piece is unlocked and pressed, and the unlocking piece and the vent pipe 4 are unlocked after being stressed, and the first movable baffle 6 continues to move horizontally under the drive of the first driving device 3, and one end of the double-headed micro-cable micro-tube quick-plug connector is detached from the vent pipe 4. At this time, the second driving device 7 begins to reset, and a second movable baffle 9 is passed through the quick-plug plug 8. A fixed slide bar 10 is also provided between the first stand 1 and the second stand 2, and a limit baffle 11 is fixed on the fixed slide bar 10. The second driving device 7 resets and drives the double-headed micro-cable micro-tube quick-plug connector inserted at the driving end to move toward the second stand 10 together, and the second movable baffle 9 moves toward the second stand 2 under the action of the reset spring 12. After the second movable baffle 9 contacts the limit baffle 11, it no longer moves. At this time, the double-headed micro-cable micro-tube quick-plug connector continues to move under the reset drive of the second driving device 7, and the unlocking piece at the other end of the double-headed micro-cable micro-tube quick-plug connector begins to be pressed tightly to unlock and disengage.

[0035] In this embodiment, the micro-cable micro-tube quick-plug connector detaches and falls between the first rack 1 and the second rack 2. By setting the lower part between the first rack 1 and the second rack 2 as an inclined surface, the quick-plug connector that has fallen off after detection slides out through the inclined surface, thereby solving the problem of sample accumulation between the racks.

[0036] In this embodiment, four ventilation pipes 4 are provided, and the quick-insert plugs 8 correspond to the ventilation pipes 4 one by one.
