A kind of vent cabinet
Technical field
The utility model relates to laboratory equipment field, specifically a kind of vent cabinet.
Background technology
The function of laboratory hood is mainly by having outside the discharge chambers such as gas with foreign flavor, toxic gas or corrosive gas of producing when testing in laboratory.When experimental implementation person uses vent cabinet, position more than operator's head need be blocked with glass sliding door, sucks mouth and nose or injury eyes to have prevented gas with foreign flavor, toxic gas, corrosive gas.
The glass sliding door opening and closing mode of vent cabinet adopts the structure promoted up and down.But traditional vent cabinet, because the problem of manufacture craft and technology is not generally furnished with vent cabinet glass sliding door stopping means, automatically can not stops when glass sliding door arrives safe altitude, manually need adjust home.Operate time, common to situation be that, when operator touches glass sliding door, because do not have the stop of stopping means, glass sliding door usually can depart from home, thus causes experimental gas to hurt human body.
Existing vent cabinet glass door frame and the handrail being arranged on doorframe bottom mainly adopt square plastic section bar to make, what glass door frame adopted is the upper and lower way of propelling, the handrail of this structural glass doorframe, during use, finger can hold the corner angle of section bar, and Long-Time Service finger has discomfort.It is relatively short that plastic material makes life cycle, and structure is firm not, and appearance color is single, looks older.And when vent cabinet needs then need the overall structure of change vent cabinet when installing left and right sliding door and select glass door frame else, have influence on manufacturing schedule so to a certain extent.
Summary of the invention
The purpose of this utility model is for above-mentioned Problems existing and deficiency, automatically stops, ensure that the safety of operator, conveniently hold and pull glass door, meet the vent cabinet of ergonomics when providing one to enable glass sliding door arrive safe altitude.
The technical solution of the utility model is achieved in that a kind of vent cabinet, comprise cabinet, by blower fan, the ventilating system of variable air rate valve and pipeline composition and control system, described cabinet comprises base cabinet and working cabined, glass sliding door is provided with before working cabined, working cabined doorframe is provided with console board, on working cabined one side plate and the stopping means be provided with between glass sliding door for limiting glass sliding door height, described stopping means comprises, one can, be arranged on to bending the stop pulling part in can, the screwed swing arm in front end, knob and back-moving spring, the front side board bottom of described can, all transmission is set on the right of right plate bottom and lower side panel, described swing arm activity is connected with stop pulling part through can front side board again, swing arm section cover between described stop pulling part and can has back-moving spring, described stop pulling part is provided with the spacing stop part that level stretches out can transmission position to the right, during installation, described can 3 hexagon socket head cap screws are fixed in the side plate of the working cabined left side, described swing arm stretches out from the through hole that the left side functional column of working cabined doorframe is provided with, knob is contained in the outer end of swing arm, the glass sliding door doorframe guide groove side of working cabined has a square hole, stop that the spacing stop part of pulling part puts in the inside of guide groove from square hole, glass sliding door doorframe is also provided with a block and is fixed on doorframe side, when glass sliding door rises to home, block on doorframe can contact with spacing stop part and be stopped and stop, continue to rise to more than home to glass sliding door, just need to be rotated in the knob on the functional column of the left side, make spacing stop part not contact ability pull-up glass sliding door with the block on doorframe, under the restoring force effect of back-moving spring, spacing stop part can spring back to origin-location, and glass sliding door is open at every turn specifies home all can automatically stop.
Further, the underframe front portion of described glass door frame is provided with handrail, described handrail comprises handrail body, be arranged on the upper circular arc handrail of the past lordosis on handrail body top and be arranged on the down convex lower circular arc handrail of handrail body bottom, is respectively equipped with upper groove and the low groove that person easy to use points force above upper circular arc handrail and below lower circular arc handrail; Handrail body bottom is provided with the caulking groove of opening upwards.
Further, in the caulking groove of described handrail body, cover has a Flexible Connector, and the other end of Flexible Connector is provided with two elastic hooks, and Flexible Connector is connected as one with underframe in the connecting hole of underframe bottom by two elastic hook fasteners.
Further, described glass sliding door comprises glass door frame and double glazing, and glass door frame is provided with interior caulking groove and outer caulking groove, inlays inside and outside layer glass respectively in interior caulking groove and outer caulking groove.
The utility model is owing to being provided with stopping means, automatically stop when enabling glass sliding door arrive safe altitude, solving can not self-braking problem when glass sliding door in the past arrives operator's safe altitude, there are gas with foreign flavor, toxic gas, corrosive gas to suck mouth and nose or injury eyes when effectively prevent experimental implementation, guarantee the personal safety of operator.
The utility model is provided with circular arc handrail and lower circular arc handrail owing to have employed in the underframe front portion of glass door frame, be respectively equipped with person easy to use above upper circular arc handrail and below lower circular arc handrail and point the upper groove of force and the structure of low groove, employ the principle of ergonomics, facilitate experimental implementation person to hold handrail and open and close glass door, the long-time finger that uses can not be felt under the weather.Use the formed in mould section combination of aluminum alloy materials to install to form, structure is attractive in appearance, corrosion-resistant.Left and right suspending steel wire rope is hidden in C shape groove completely, avoids and contacts with the corrosive gas in cabinet.Convenient during installation, sound construction.When glass door frame needs to install horizontal sliding door, only need on doorframe, separately add an accessory and just can realize horizontal sliding door is installed.
The utility model is interior caulking groove and outer caulking groove because glass door frame is provided with, and inlays inside and outside layer glass respectively in interior caulking groove and outer caulking groove, solves in the past the shortcomings such as the hermetic seal of one side glass is poor, sound-insulating and heat-insulating is poor, easy Tibetan dust.
Below in conjunction with accompanying drawing, the utility model is further described.
