For a plurality of air switches in a row, a plurality of devices are required to be connected in series. In the process, when the engagement plates 201a are inserted into each other, the telescopic columns 201b at the ends of the engagement arms 102c are squeezed to be retracted into the engagement arms 102c, when the engagement plates 201a move inward, the first connecting rods 201c connected with the telescopic columns 201b rotate, and when the first connecting rods 201c rotate, the second connecting rods 201d are driven to move horizontally, the shifting rods 201d-1 at the ends of the second connecting rods 201d move through the wedge-shaped blocks 201e-1 and shift the locking columns 201e to exit from the locking holes 101c-2 of the clamping plates 101c, and the clamping plates 101c are unlocked and can be extracted to be used as a device for fixing the signboard 101d and placed in the slide rails 101b of the mounting seats 101a.
Since the air switches have different sizes, the air switches do not correspond to the air switches below in order to prevent the plurality of mounting bases 101a from being shifted in position after being connected in series. When the clamping bar is connected, the pressing plate 202b-2 can be pulled, the adjusting rod 202b moves inwards at the moment, the clamping block 102d is separated from the connecting plate 102b and the clamping arm 102c, the clamping arm 102c is separated from the second spring 102a and can freely stretch and retract, the installation seat 101a is guaranteed to be positioned right above the air switch, and the toothed plate 202b-1 at the end part of the adjusting rod 202b is matched with the toothed rack 202d on the outer side of the installation seat 101a, so that the clamping arm 102c can be guaranteed to stop at any place.
After the bases are installed, the signboard 101d written with different signs is inserted between the two boards 101c in the slide rail 101 b. In the process of insertion, the two clamping plates 101c move towards two sides, when the clamping plates 101c move, the two clamping plates push against the ejector block 301b-1 to move, so that the first sliding rod 301b moves horizontally, the sixth spring 301d drives the second sliding rod 301c to move, and the second sliding rod 301c pulls the claw 301e to hook the clamping plate 101c at the end of the clamping arm 102c, so that the clamping plate is further clamped on two sides of the opening switch. It should be noted that when used in a plurality of air switches in a row, only the leftmost and rightmost fingers 301e need to be retained, and the rest can be turned over to avoid obstructing installation.
The device can be used on a single air switch and also can be used on a plurality of air switches in a row, so that the detached parts can also be directly used for fixing the signboard.
It should be noted that the above-mentioned embodiments are only for illustrating the technical solutions of the present invention and not for limiting, and although the present invention has been described in detail with reference to the preferred embodiments, it should be understood by those skilled in the art that modifications or equivalent substitutions may be made on the technical solutions of the present invention without departing from the spirit and scope of the technical solutions of the present invention, which should be covered by the claims of the present invention.
