Description

Technical Field

[0001] This utility model relates to the field of gas supply connectors, and in particular to an automatic dustproof mechanism for gas supply in parking stations. Background Technology

[0002] In the field of industrial automation, air supply for parking stations is widely used as a convenient and highly reliable mechanical drive solution. However, since parking stations are generally located near welding and other work sites, welding slag and other impurities often enter the air supply connectors, affecting the normal operation of the air supply mechanism. Existing solutions are generally divided into two types: internal dust prevention mechanisms and external dust prevention mechanisms. Internal dust prevention mechanisms involve installing a filter screen inside the connector. These mechanisms are relatively small and can prevent impurities with a diameter exceeding a certain threshold from entering the air supply mechanism, but these particles can still adhere to the inner wall of the air connector. External dust prevention mechanisms involve installing a dust cover outside the connector. These mechanisms can prevent impurities from entering the connector, but they are larger and are generally manually operated, only able to be manually shut down when the production line is stopped.

[0003] Therefore, it is necessary to improve such a structure to overcome the above-mentioned defects. Utility Model Content

[0004] The purpose of this utility model is to overcome the shortcomings of the prior art and provide an automatic dust prevention mechanism for air supply in parking stations. This utility model is achieved through the following technical solution:

[0005] An automatic dustproof mechanism for gas supply in a parking station includes a first base plate and a second base plate. A female gas inlet is provided through the first base plate, and a male gas inlet is provided through the second base plate. The second base plate can be close to or away from the first base plate. A trigger platform is also slidably provided on the first base plate. The trigger platform can move up and down. A dust cover is rotatably provided on the trigger platform. A reset mechanism is provided on the dust cover to make the dust cover tend to maintain a horizontal posture. A trigger push rod is fixedly provided on the second base plate, and the trigger push rod is located above the trigger platform.

[0006] In the above technical solution: the first base plate is used to set the relevant structures on the parking station side; the second base plate is used to set the relevant structures on the tool side; the air connector and the air connector are used to connect the pipeline after mating; the up and down movement of the trigger platform is used to control the opening and closing of the dust cover; the dust cover is used to connect the air connector to the air connector to prevent dust when the air connector and the air connector are not connected; the reset mechanism is used to reset the dust cover; the trigger push rod is used to enable the trigger platform and the second base plate to move synchronously, so that the dust cover will only open when the air connector and the air connector are mated.

[0007] A further feature of this invention is that the reset mechanism is a reset spring, and the reset spring is disposed at the rotational connection shaft between the dust cover and the trigger platform. One end of the reset spring is fixedly connected to the dust cover, and the other end is fixedly connected to the trigger platform.

[0008] In the above technical solution: the reset spring is set at the rotating connection shaft between the dust cover and the trigger platform, so that when the dust cover rotates due to the obstruction of the side of the first base plate when the trigger platform moves downward, it can accumulate elastic potential energy, so as to release the elastic potential energy when the trigger platform moves upward in the subsequent stage, thereby covering the connecting female head to prevent dust.

[0009] A further feature of this invention is that: a receiving groove is provided on the triggering platform, and the dust cover is rotatably disposed in the receiving groove; the width of the receiving groove is not less than the width of the dust cover, and the depth of the receiving groove is not less than the thickness of the dust cover.

[0010] In the above technical solution: the placement groove is used to store the dust cover when the male and female connectors are mated, so as to avoid interference between the dust cover and the side position of the first base plate.

[0011] A further feature of this invention is that the side of the trigger platform with the receiving groove is parallel to the side of the first base plate, and the distance between the two is less than the thickness of the dust cover.

[0012] In the above technical solution, the corresponding setting of the size of the dust cover and the size of the receiving groove is used to avoid interference between the dust cover and the first base plate.

[0013] A further feature of this invention is that: a mounting plate is fixedly mounted on the first base plate, at least two guide rods are fixedly mounted on the mounting plate, and at least two guide holes are provided on the trigger platform, with the guide holes slidably connected to the guide rods.

[0014] In the above technical solution: the mounting plate is used to set the guide rod and determine the position of the trigger platform through the guide rod; the guide hole is used to cooperate with the guide rod so that the trajectory of the trigger platform moving up and down is fixed.

[0015] A further feature of this invention is that a spring is also fitted onto the guide rod, with one end of the spring contacting the mounting plate and the other end contacting the trigger platform.

[0016] In the above technical solution: the spring is used to enable the triggering platform to contact the triggering push rod.

[0017] A further feature of this invention is that the first base plate is provided with a plurality of guide shafts, and the second base plate is provided with a plurality of guide holes, wherein the positions of the guide shafts correspond to the positions of the guide holes.

[0018] In the above technical solution, the guide shaft and guide hole are designed to make the vertical movement trajectory of the second base plate inconvenient and to ensure accurate docking of the male and female connectors.

[0019] This utility model discloses an automatic dust prevention mechanism for gas supply in parking stations, which, compared with the prior art:

[0020] 1. This utility model, by setting up a dust cover, a reset spring, a trigger platform, and a trigger push rod, enables the dust cover to be opened when the female and male connectors are mated, while keeping the dust cover closed at other times, thereby improving the dustproof effect and preventing impurity particles from entering the connector.

[0021] 2. This utility model also uses the setting of spring, guide rod and guide hole to make the dust cover linked with the first base plate, so that the cover can be opened automatically during docking without the production line stopping. Attached Figure Description
