Similarly, the second end of the first rail 120 is provided with a second pulley, and the second pulley is arranged in the second guide rail, so that the first rail 120 can fall along the second guide rail more easily. Wherein, dustproof curtain adopts folding curtain cloth, is convenient for fold and expand, and it is more convenient to use.

Referring to fig. 3, a second cross bar 140 is connected to the upper end of the dust curtain, and the second cross bar 140 is connected to the top of the case 100. Specifically, a hook (not shown) is disposed at the top of the box 100, and the second cross bar 140 is clamped to the hook. In the assembly process, the second cross rod 140 is clamped on the clamping hook, the connection mode is simple and convenient, the dustproof curtain is convenient to replace, and the maintenance is convenient.

The special-shaped clamping piece 131 is formed by processing a sheet metal sheet, and the thickness of the sheet metal sheet is thin, so that the special-shaped clamping piece 131 can be tightly attached to the inner wall of the box body 100, thereby reducing gaps between a dustproof curtain and the top of the box body 100 and improving the dustproof shielding effect. It should be noted that, the second cross bar 140 may be provided with a recess for avoiding the shaped fastening member 131.

Referring to fig. 3, in order to improve the dust-proof effect, a seal groove 101 is provided at the front end of the case 100, and the door 200 can be covered on the seal groove 101. A sealing strip is installed in the sealing groove 101. Through seal groove 101 and sealing strip, can improve the leakproofness between box 100 and the chamber door 200, reduce in the dust gets into box 100, and dustproof curtain can block dust pollution electrical component under the condition that appears the gap between box 100 and chamber door 200, provide better dustproof effect.

The embodiments of the present utility model have been described in detail with reference to the accompanying drawings, but the present utility model is not limited to the above embodiments, and various changes can be made within the knowledge of one of ordinary skill in the art without departing from the spirit of the present utility model.
