Sample box opening/closing device
Technical field
The utility model relates to start-stop system, refers to the opening/closing device opened and closed the wind sample presentation box transporting sample particularly.
Background technology
Device for releasing closures is the instrument of modernism sample presentation indispensability, and old-fashioned wind sample presentation shell adopts rotation to uncap pattern, and for mating modern full automaticity wind sample presentation, sample box changes extruded sample box into, so steelworks scene needs a manual opening cover device.Because device for releasing closures is fixed measure, and conventional shell is divided into multiple size: 189mm, 190mm, 196mm etc., and often kind of shell bore need be equipped with device for releasing closures corresponding thereto.Meanwhile, common device for releasing closures is all use cylinder, and be provided with two fixing switch over travels, the position of travel switch sets for shell, therefore can only be applicable to a kind of shell of model size.Therefore, the manual opening cover device of multiple stage different model, type and size is just had to be equipped with in production scene, adds maintenance and the cost used.
Summary of the invention
The purpose of this utility model is to provide a kind of sample box opening/closing device, can not only the sample box of compatible sizes open and close, simultaneously need not the dismounting of actuating device and easy to maintenance, and durability is strong, trouble point is few.
For achieving the above object, the sample box opening/closing device of the utility model design, for opening and closing sample box, is characterized in that: it comprises the housing of a side opening and is located at the dividing plate in housing, housing being divided into atrium and enclosed cavity; Be provided with rotating shaft in described enclosed cavity, described rotating shaft and housing sidewall are rotationally connected, and described rotating shaft one end is connected with the control lever be located at outside housing, and described rotating shaft is provided with gear; The tooth bar that described dividing plate sliding block joint one is vertically arranged, described gear engages with described tooth bar; Be provided with sample box pedestal in described atrium, described sample box pedestal is provided with the first opening bottom engaging sample box; Be provided with portable plate above described sample box pedestal, described portable plate is provided with the second opening of engaging sample lid, and described portable plate one end is connected with described tooth bar through dividing plate, and described dividing plate is provided with the breach being not less than described portable plate stroke.
Further, described dividing plate is fixedly connected with tooth bar seat, described tooth bar seat is provided with rack slide, and described tooth bar slides and is embedded in described rack slide.
Further, described first opening and/or the second opening are U-shaped opening.
Further, described first overthe openings is also provided with caulking groove.Like this, inserting with spacing of sample box is facilitated.
Further, the two opposite side walls that described housing is positioned at atrium is provided with at least two group regulating tanks; Regulating part is connected with sample box pedestal through regulating tank, and sample box pedestal is fixed on any position in regulating tank stroke.
Further, described regulating part comprises and stretching in sample box pedestal and the adjust bar stretched out in regulating tank, is threaded and end face is connected to the setting nut of housing sidewall with adjust bar.
Further, described control lever comprises the handle set be connected with rotating shaft, the handle be connected with handle set.
The beneficial effects of the utility model are: the utility model is specifically designed to and opens and closes transporting the wind sample presentation box of sample, need not cylinder equal energy source medium, and equipment cost reduces 50%; Adopt manual operation, and simple to operate, laborsaving, not only reduce the fault rate of equipment, ensure that the promptness rate in steel-making laboratory.

Detailed description of the invention
As depicted in figs. 1 and 2, the sample box opening/closing device of the utility model design, for opening and closing sample box, it comprises the housing 1 of a side opening and is located at the dividing plate 2 in housing 1, housing 1 being divided into atrium 1.1 and enclosed cavity 1.2; Be provided with rotating shaft 3 in described enclosed cavity 1.2, described rotating shaft 3 is rotationally connected with housing 1 sidewall, and described rotating shaft 3 one end is connected with the control lever 4 be located at outside housing 1, and described rotating shaft 3 is provided with gear 5; The tooth bar 6 that described dividing plate 2 sliding block joint one is vertically arranged, described gear 5 engages with described tooth bar 6; Be provided with sample box pedestal 7 in described atrium 1.1, described sample box pedestal 7 is provided with the first opening 7.1 bottom engaging sample box; Be provided with portable plate 8 above described sample box pedestal 7, described portable plate 8 is provided with the second opening 8.1 of engaging sample lid, and described one end is connected with described tooth bar 6 through dividing plate 2, and described dividing plate 2 is provided with the breach 2.1 being not less than described portable plate 8 stroke.Further, described first opening 7.1 and/or the second opening 8.1 are U-shaped opening.Further, described sample box pedestal 7 is also provided with and is convenient to sample box and inserts and spacing caulking groove 7.2, described caulking groove 7.2 is positioned at the first overthe openings.
Again as shown in Figure 2, further, described dividing plate 2 is fixedly connected with tooth bar seat 9, described tooth bar seat 9 is provided with rack slide 9.1, and described tooth bar 6 slides and is embedded in described rack slide 9.1.
As illustrated in figs. 1 and 2 again, further, the two opposite side walls that described housing 1 is positioned at atrium 1.1 is provided with at least two group regulating tanks 1.3; Regulating part 10 is connected with sample box pedestal 7 through regulating tank 1.3, sample box pedestal 7 is fixed on any position in regulating tank 1.3 stroke.Further, described regulating part 10 comprises and stretching in sample box pedestal 7 and the adjust bar 10.1 stretched out in regulating tank 1.3, is threaded and end face is connected to the setting nut 10.2 of housing 1 sidewall with adjust bar 10.1.Unclamp setting nut 10.2, adjust bar 10.1 moved to suitable position, then tighten setting nut 10.2 complete sample box pedestal 7 height regulate.
Again as shown in Figure 2, further, described control lever 4 comprises the handle set 4.1 be connected with rotating shaft 3, the handle 4.2 be connected with handle set 4.1.
Sample box is placed in atrium 1.1, and by being fastened in the first opening 1.1 bottom sample box, sample lid is fastened in the second opening 1.2.Lift handle 4.2, rotating shaft 3 is rotated, thus driven gear 5, promote tooth bar 6 and upwards operate, sample lid upwards for dynamic, is opened by rack drives portable plate 8; Put into steel sample in sample box, being placed in by sample box in atrium 1.1, to pressing down handle, sample lid is closed tight to lower cover by portable plate 8.
