Abstract
Description
Technical Field
[0001] This utility model relates to the field of airtightness testing fixtures, and in particular to a turn signal airtightness testing fixture. Background Technology
[0002] Car rearview mirrors are located on the left and right sides of the front of the car, as well as in the front of the interior. They reflect the situation behind, to the sides, and below the car, allowing the driver to indirectly see these areas, acting as a "second eye" and expanding the driver's field of vision. Currently, some car models have turn signals integrated into their rearview mirrors to alert vehicles behind. To prevent water from entering the turn signals during daily use, they undergo an airtightness test before leaving the factory to ensure good airtightness. Traditional airtightness testing typically uses water testing; however, water residue on the turn signal surface is difficult to clean after a water test. If water leaks into the turn signal, it can damage the internal circuit board, making it unusable for recycling and increasing production costs. Utility Model Content

For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.
[0026] like Figures 1 to 5As shown, a turn signal airtightness testing fixture includes a base 1, which is set on a workbench (not shown in the figure). A test block 6 for airtightness testing of a turn signal 2 is set below the base 1. A mounting groove 3 for accommodating the turn signal 2 is opened on the top of the base 1. A side groove 4 is opened on the side wall of the base 1, which is connected to the mounting groove 3. A test hole 5 is opened at the bottom of the base 1, which is connected to the mounting groove 3. The test block 6 is set in the test hole 5. An air inflation channel is opened inside the test block 6. An air inlet pipe 7 and an air outlet pipe 18 are connected to the test block 6. Both the air inlet pipe 7 and the air outlet pipe 18 are connected to the air inflation channel. The air inlet pipe 7 is located on the side wall of the test block 6, and the air outlet pipe 18 is located on the top surface of the test block 6. A sealing plate 8 is also rotatably set on the test block 6. The sealing plate 8 is located on one side of the test block 6 and is located in the side groove 4.
[0027] In this utility model, the turn signal 2 is placed in the mounting groove 3 of the base 1. The bottom of the turn signal 2 has a wiring hole for wiring, and one side of the turn signal 2 also has a mounting hole for engaging with the rearview mirror. After the turn signal 2 is placed in the mounting groove 3, the air outlet pipe 18 can be inserted into the interior of the turn signal 2 through the wiring hole. The top surface of the detection block 6 is tightly fitted with the bottom surface of the turn signal 2 to seal the wiring hole. The mounting hole on one side of the turn signal 2 is located on one side of the side groove 4. The sealing plate 8 is fitted with one side of the turn signal 2 and can seal the mounting hole on one side of the turn signal 2. Then, the air inlet pipe 7 is connected to an external inflation device, which can be an air compressor, to inject air into the interior of the turn signal 2. Since the holes of the turn signal 2 are sealed, the air tightness of the turn signal 2 can be tested. If the turn signal 2 does not leak air, it proves that the air tightness is good.
[0028] Furthermore, a first support rod 9 is fixedly connected to the bottom of the base 1. The first support rod 9 is fixedly connected to the workbench and the base 1 is fixedly connected by bolts. The first support rod 9 is used to support the base 1, leaving a certain space below the base 1. The bottom of the detection block 6 is provided with a first telescopic member 10. The first telescopic member 10 is located below the base 1. The fixed end of the first telescopic member 10 is fixedly set on the workbench, and the movable end of the first telescopic member is fixedly connected to the bottom of the detection block 6. The telescopic movement of the movable end of the first telescopic member 10 can drive the detection block 6 to slide up and down in the detection hole 5. When the turn signal 2 is placed in the mounting slot 3, the movable end of the first telescopic member 10 extends out, which can make the top surface of the detection block 6 fit tightly with the bottom surface of the turn signal 2, thereby completely sealing the wiring hole.
[0029] Furthermore, a second telescopic member 11 is horizontally provided on one side of the base 1. The fixed end of the second telescopic member 11 is fixedly connected to the third support rod 21, which is fixedly set on the workbench. The movable end of the second telescopic member 11 is fixedly connected to a side pressure rod 12. The side pressure rod 12 has an L-shaped structure. The end of the side pressure rod 12 away from the second telescopic member 11 is located in the side groove 4 and abuts against the sealing plate 8. In this embodiment, when the turn signal 2 is placed in the mounting groove 3, the movable end of the second telescopic member 11 drives the side pressure rod 12 to move to one side of the turn signal 2. The side pressure rod 12 can drive the sealing plate 8 to rotate to one side of the turn signal 2, so that the sealing plate 8 is tightly fitted to one side of the turn signal 2. The sealing plate 8 can seal the mounting hole on one side of the turn signal 2. After the test is completed, the movable end of the second telescopic member 11 drives the side pressure rod 12 to reset, so that the turn signal 2 can be taken out from the mounting groove 3.
[0030] Furthermore, such as Figure 5 As shown, a rotating shaft is fixedly provided on the detection block 6, and the sealing plate 8 is rotatably mounted on the rotating shaft. An elastic element is provided between the sealing plate 8 and the rotating shaft. A limiting plate 19 is also fixedly provided on the detection block 6. The limiting plate 19 is located on the side away from the turn signal 2. In this embodiment, the elastic element is a torsion spring. One end of the elastic element is fixedly connected to the sealing plate 8, and the other end is fixedly connected to the detection block 6. Under normal conditions, the sealing plate 8 deflects to the side away from the turn signal 2 under the action of the elastic element, and the sealing plate 8 abuts against the limiting plate 19. The limiting plate 19 can limit the sealing plate 8. When performing an airtightness test, the sealing plate 8 rotates to the side closer to the turn signal 2 under the action of the side pressure rod 12, so that the sealing plate 8 seals the turn signal 2. During the rotation of the sealing plate 8, the elastic element is deformed. After the test is completed, the side pressure rod 12 retracts, the sealing plate 8 is reset under the action of the elastic element, and the sealing plate 8 abuts against the limiting plate 19 again.
[0031] Furthermore, a third telescopic component 13 is provided, which is fixedly installed on one side of the base 1. The fixed end of the third telescopic component 13 is fixedly installed on the workbench, and the movable end of the third telescopic component 13 is fixedly connected to a clamping rod 14. The clamping rod 14 is located above the base 1, and the third telescopic component 13 can drive the clamping rod 14 to move up and down. A clamping head 15 is fixedly installed at the end of the clamping rod 14 away from the third telescopic component 13. The clamping head 15 can clamp the turn light 2 in the mounting groove 3 to prevent the turn light 2 from being blown out of the mounting groove 3 during the inflation process.
[0032] Furthermore, a marking component is also provided, which includes a fourth telescopic member 16. The fourth telescopic member 16 is located on one side of the base 1. The fixed end of the fourth telescopic member 16 is fixedly connected to the second support rod 20, and the second support rod 20 is fixedly connected to the workbench. The movable end of the fourth telescopic member 16 is fixedly connected to a marking pen 17. The tip of the marking pen 17 faces the turn signal 2. After the turn signal 2 is tested for air tightness, if the air tightness of the turn signal 2 is good, the movable end of the fourth telescopic member 16 extends, driving the marking pen 17 to move closer to the turn signal 2. The marking pen 17 can mark points on the turn signal 2 to mark the turn signal 2. In subsequent statistics, it can be seen intuitively whether the turn signal 2 is qualified.
[0033] It should be noted that the first telescopic member 10, the second telescopic member 11, the third telescopic member 13 and the fourth telescopic member 16 in this utility model are all cylinders. The fixed end of the cylinder is the cylinder barrel and the moving end of the cylinder is the piston rod.
[0034] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and not to limit it; although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features; and these modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of this utility model.
