In the figure: 1. a metal tube; 2. an embedding opening; 3. a curtain; 4. a fixed block; 5. a telescopic rod is provided.

Detailed Description

The technical solution of the present invention will be described clearly and completely with reference to the accompanying drawings, and obviously, the described embodiments are only some embodiments, not all embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by a person skilled in the art without creative efforts belong to the protection scope of the present invention.

The utility model provides a rail is used in filter leak hunting when carrying out the leak hunting to the high efficiency filter in the clean room or laminar flow filter, plays the effect that prevents around the air current disturbance from disturbing leak hunting data. The fence comprises a metal pipe 1, wherein soft magnets are arranged at the upper end of the metal pipe 1 and connected with a metal frame of a filter, a curtain 3 is fixedly connected to the lower end of the metal pipe 1, and embedding openings 2 are formed in two ends of the metal pipe 1. Because under general conditions, the frame of the filter in the clean room all is metallic, so the utility model discloses a soft magnet and the absorption fixed action of filter metal frame, on the metal frame of filter is fixed with tubular metal resonator 1, the curtain 3 that the 1 lower extreme of tubular metal resonator is connected realizes blockking to the air current on every side, avoids the air current disturbance on every side to influence the exactness of leak hunting result.

Specifically, the metal pipe 1 is a square hollow metal pipe 1. The hollow metal tube 1 is internally provided with a telescopic rod 5. The telescopic rod 5 is a plurality of loop bars which are connected together in a rotating way through threads. In practical application, two loop bars can be selected for screw thread rotary connection to form the telescopic rod 5, and the length of the telescopic rod 5 can be adjusted by screwing in or screwing out the screw thread rotary connection.

In addition, when the size of the frame of the filter is larger than the length of the fence, and a plurality of fences need to be connected in series, the series connection between the fences is realized through the embedding ports 2 at the two ends of the metal pipe 1, and the use requirements of filters in different sizes are met. In general, the metal pipe 1 has a male end fitting 2 and a female end fitting 2. The series connection between different fences is realized through the mutual matching of the male structure and the female structure.

In one embodiment, the metal pipe 1 may have a pin structure at one end fitting port 2 and a socket structure at the other end fitting port 2. Fixed connection between the metal tubes 1 is realized by inserting the contact pins into the slots, so that series connection between different fences is realized, and the use requirements of filters of different sizes are met.

The series connection of a plurality of fences can be a straight line series connection realized by end-to-end connection of the embedded openings 2 of the metal pipes 1 around a single side of a plurality of filters, or a fence series connection for blocking airflow disturbance around a single filter and realized around the periphery of the filter.

In order to improve the stability of the fixed connection of the metal tube 1 and the filter frame, two ends of the telescopic rod 5 can extend out of the hollow metal tube 1, and the end of the extending part is placed and fixed on the bracket.

In addition, in order to further improve the stability, a rectangular groove may be formed in the side surface of the hollow metal tube 1, and a fixing block 4 may be inserted into the rectangular groove to fixedly support the plurality of loop bars in the hollow metal tube 1.

Further, the lower part of fixed block 4 is the arc opening, the arc opening and the external diameter phase-match of telescopic rod 5. The fixed block 4 is inserted into the rectangular groove of the metal pipe 1, and the telescopic rod 5 is wrapped through the arc-shaped opening, so that the telescopic rod 5 is supported and fixed.
