Detailed Description
The technical solution of the present invention will be further explained with reference to the accompanying drawings.
Referring to fig. 1-5, the housing of the direct-reading dust detector includes a bottom case 1, a top case 2 detachably disposed on the bottom case 1, a plurality of third threaded holes 10 are disposed on two side edges of the bottom case 1, a plurality of one-to-one fourth threaded holes 11 disposed above the third threaded holes 10 are disposed on two side edges of the top case 2, and the housing further includes locking bolts inserted into the third threaded holes 10 and the corresponding fourth threaded holes 11.
In the present embodiment, referring to fig. 3 and 5, the bottom shell 1 has four third threaded holes 10 opened along each side of the length direction thereof, and the top shell 2 has four fourth threaded holes 11 opened along each side of the length direction thereof. Through this setting, the dismouting is swift convenient between drain pan 1 and the top shell 2.
Above-mentioned direct-reading dust detector's housing still includes first slot 3 of locating drain pan 1 one end, locate 2 one end of top shell and be located the second slot 4 directly over first slot 3, can pull out the end plate 5 of locating in first slot 3 and second slot 4 of inserting. The opening direction of the first slot 3 faces the second slot 4, and the opening direction of the second slot 4 faces the first slot 3. That is, the first slot 3 is opened upward, the second slot 4 is opened downward, the lower end of the end plate 5 is inserted into the first slot 3, and the upper end of the end plate 5 is inserted into the second slot 4. The bottom shell 1, the top shell 2 and the end plate 5 enclose each other to form a sealed shell.
The housing of the direct-reading dust detector further comprises a first mounting mechanism arranged on the end plate 5 and used for mounting the dust sampling head 6 in a matching mode, and a second mounting mechanism arranged on the end plate 5 and used for mounting the temperature and humidity sensor 7 in a matching mode. Dust sampling head 6 and temperature and humidity sensor 7 are all detachable and are located on end plate 5.
