Abstract
The utility model discloses an over -and -under type exhaust hood, including the fan housing mouth, wherein, the fan housing mouth passes through telescopic tube and links to each other with the exhaust pipe, telescopic tube is including cup jointing continuous interior sleeve pipe and outer tube, overlap the outside of tubes including outer tube one end is cup jointed, the other end cup joints outside the exhaust pipe, be equipped with the wire rope riser on the outer tube, be equipped with the operation bracelet on the fan housing mouth, the operation bracelet that goes up and down links to each other through lift pulley and wire rope riser, the figure of lift pulley is two, and bilateral symmetry sets up, be equipped with perpendicular balancing weight on the wire rope riser, the continuous keep balance of two lift pulleys of the perpendicular balancing weight and the left and right sides. The utility model provides an it is continuous with fan housing mouth and exhaust pipe through telescopic tube, utilize lift pulley and wire rope to go up and down conveniently to realize upper and lower liter of fan housing mouth and contract to the efficiency that the operator worked had both been satisfied, the demand of the volume of airing exhaust on the control post that also can be fine, and simple structure, easy to carry out.
Description
Technical field
This utility model relates to a kind of exhaust hood, particularly relates to a kind of lift exhaust hood.
Background technology
In ventilating system, conventional exhaust hood does not have Telescopic, can only be single post is carried out air draft.If strictly controlling for post air draft, conventional exhaust hood cannot meet.Therefore, it is necessary to existing exhaust hood structure is improved, it is provided that a kind of lift exhaust hood.
Utility model content
Technical problem to be solved in the utility model is to provide a kind of lift exhaust hood, it is possible to conveniently realize upper and lower reduction, has both met the efficiency of operator's work, also can well control the demand of exhaust air rate on post.
This utility model employed technical scheme comprise that a kind of lift exhaust hood of offer for solving above-mentioned technical problem, including fan housing mouth, wherein, described fan housing mouth is connected with exhaust duct by telescopic tube, described telescopic tube includes inner sleeve and the trocar sheath that socket is connected, described trocar sheath one end is socketed in outside inner sleeve, the other end is socketed in outside exhaust duct, described trocar sheath is provided with steel wire rope lifter, described fan housing mouth is provided with descending operation bracelet, and described descending operation bracelet is connected with steel wire rope lifter by lifting pulley.
Above-mentioned lift exhaust hood, wherein, the number of described lifting pulley is two, is symmetrical set, and described steel wire rope lifter is provided with vertical counter-weight block, and described vertical counter-weight block is connected with two, left and right lifting pulley and keeps balance.
This utility model contrast prior art has following beneficial effect: the lift exhaust hood that this utility model provides, by telescopic tube, fan housing mouth is connected with exhaust duct, lifting pulley and steel wire rope lifting is utilized to conveniently realize the upper and lower reduction of fan housing mouth, thus both having met the efficiency of operator's work, also the demand of exhaust air rate on post can well be controlled, and simple in construction, it is easy to implement.

Detailed description of the invention
Below in conjunction with drawings and Examples, the utility model will be further described.
Fig. 1 is this utility model lift exhaust hood structure schematic diagram.
Refer to Fig. 1, the lift exhaust hood that this utility model provides, including fan housing mouth 8, wherein, described fan housing mouth 8 is connected with exhaust duct 9 by telescopic tube, described telescopic tube includes inner sleeve 6 and the trocar sheath 2 that socket is connected, described trocar sheath 2 one end is socketed in outside inner sleeve 6, the other end is socketed in outside exhaust duct 9, described trocar sheath 2 is provided with steel wire rope lifter 4, described fan housing mouth 8 is provided with descending operation bracelet 7, and described descending operation bracelet 7 is connected with steel wire rope lifter 4 by lifting pulley 1.
The lift exhaust hood that this utility model provides, wherein, the number of described lifting pulley 1 is two, is symmetrical set, and described steel wire rope lifter 4 is provided with vertical counter-weight block 3, and described vertical counter-weight block 3 is connected with two, left and right lifting pulley 1 and keeps balance.Trocar sheath 2 can arrange the axis of guide 5.
The lift exhaust hood that this utility model provides, is pulled by descending operation bracelet about 7, and while pulling descending operation bracelet 7, lifting pulley 1 drives vertical counter-weight block 3, traction steel wire lifter 4, and is carried out one by one by the axis of guide 5.In technique, optional rustless steel makes, it is ensured that the quality of exhaust hood is with attractive in appearance.In ventilating system, also just with operator, the air draft in post is played an important role.
Although this utility model discloses as above with preferred embodiment; so it is not limited to this utility model; any those skilled in the art; without departing from spirit and scope of the present utility model; when doing a little amendment and perfect, therefore protection domain of the present utility model is when with being as the criterion that claims define.
