Abstract
The utility model relates to an automatic positioning mechanism for counter weight lifting doors, which comprises a frame. The front end of both sides of the frame is respectively provided with a guide rail clamped with a cabinet door which can move up and down, and two edges of the cabinet door are respectively connected to a rope which turned to extend out through an upper pulley wheel and downward connected to the upper end of a main counter weight board through a pulley wheel. Both sides of the main counter weight board are respectively arranged in a guide groove, and a secondary counter weight board which is wider than the guide groove is arranged on the main counter weight board, and a hook piece arranged on the upper end of the secondary counter weight board is to hook the main counter weight board. The whole weight of the two counter weight boards is equal to the weight of the cabinet door, and the upper end of both sides of the secondary counter weight board is respectively provided with a stop board, wherein, the surface corresponding to the guide groove is provided with a positioning wheel. The utility model has the advantages of reasonable structure, easy cabinet door positioning, accurate positioning, energy saving, convenient operation, etc.
Description
The utility model relates to a kind of counterweight overhead door automatic positioning mechanism, refers to that especially a kind of cabinet door of testing with exhaust gas cabinet that makes allows the operation aperture of cabinet door produce the location structure that extremely partly closes left and right sides state from the home of closing in mechanical mode.
Known general this overhead door structure as shown in Figure 6, the moving door of exhaust gas cabinet only has the function of moving up and down, when in exhaust gas cabinet, doing experiment, need the function of bleeding, if rate of air sucked in required is one regularly, then more the move up surface wind speed of opening portion of cabinet door is littler, otherwise it is stronger, this all can influence, and generation is bad, and the cabinet door is difficult to accurate location, and deciliter experimental implementation etc. is carried out in inconvenience.
The purpose of this utility model is to provide a kind of counterweight overhead door automatic positioning mechanism, the cabinet door has the function in home of closing and the easy location of operation aperture part, and have standard-sized sheet installation site to operation aperture part and return the function of closing automatically, so that experiment is accurate with the cabinet door location of exhaust gas cabinet, conveniently closing the experiment of branch carries out, air-flow in also preventing to bleed leaks, save and use the energy, allow the experimenter that operating means is more easily arranged, more can prevent the experimenter to test to do half to forget to close leaking that the cabinet door caused, to increase safety in utilization.
The purpose of this utility model is achieved in that a kind of counterweight overhead door automatic positioning mechanism, it comprises a framework, front end respectively is provided with a guide rail in the framework both sides, the guide rail card has a cabinet door moving up and down, in the both sides of cabinet door, respectively be connected to a rope, rope outwards passes through the pulley turnover of upper end, be connected to the upper end of a main Weight plate downwards with a pulley, main Weight plate both sides respectively place a guide groove, and other is provided with Weight plate one time, inferior Weight plate is wider than guide groove, sheet is colluded in upper end in inferior Weight plate, catches on main Weight plate, and the summation of two Weight plates and cabinet door etc. are heavy, respectively there is a baffle plate upper end, both sides of inferior Weight plate, and retaining is pulled corresponding guide groove appearance and established locating wheel.
According to the technique scheme analysis as can be known, the utility model utilization master, inferior Weight plate and pulley, the rope winding, the cabinet door has the latter half function of location easily, and produce the function that the first half is gone back to the pass automatically, so that experiment is accurate with the cabinet door location of exhaust gas cabinet, convenient experiment is carried out, and the air-flow in also preventing to bleed leaks, save and use the energy, allow the experimenter that operating means is more easily arranged, particularly experiment is carried out half, often need add the situation of medicine or observed result, at this moment the utility model need not all to open the cabinet door, can open suitable operation aperture according to need, this opening is changeable, even if forgotten the pass, also can not influence the carrying out of experiment, increase the safety of using, and low cost, than full-automatic induction type control device simple and wear well, wherein can set the position of counterweight, with the automatic height of opening of switch board door.
Below in conjunction with accompanying drawing and specific embodiments the utility model is described in further detail.
Fig. 1 is a stereogram of the present utility model.
Fig. 2 is a three-dimensional rear view of the present utility model.
Fig. 3 is a three-dimensional exploded view of the present utility model.
Fig. 4 is semi-automatic time OFF state side-looking action diagram of the present utility model.
Fig. 5 is a semi-automatic location attitude side-looking action diagram down of the present utility model.
Fig. 6 is known stereogram.
The utility model is a kind of counterweight overhead door automatic positioning mechanism, extremely shown in Figure 5 as Fig. 1, be useful on the exhaust gas cabinet 1 for experiment, this exhaust gas cabinet has a framework 10, respectively be provided with the cabinet door 12 that a guide rail 11 card moves formula on having at both sides front end on the framework 10, stage casing, the both sides inner face of cabinet door 12 respectively is connected to a rope 13, by rope 13 and cabinet door 12 joints can divide into door first and second, second is that the home of closing is to the operation aperture position of opening, first is the be provided with installation site of operation aperture position to standard-sized sheet, after rope 13 passes trailing flank backward through pulley 14 turnover of upper end, after turning to parallel trailing flank with pulley 15 again, be connected to the upper end of a main Weight plate 17 in addition downwards through a pulley 16, make in the two side ends of main Weight plate 17 and a pair of guide groove 18 and move, other is provided with Weight plate 19 one time, inferior Weight plate 19 is wider than the spacing of two guide grooves 18, on the centre of inferior Weight plate 19, kick one and collude sheet 20 with place 171 in the middle of the end face that catches on main Weight plate 17, two Weight plates 17,19 gross weight is identical with the weight of cabinet door 12, so that cabinet door 12 second can be motionless in opening the arbitrary position balance in back, because heavy equilibrium states such as the Weight plate group of cabinet door in front and back is, kicking on the both sides of inferior Weight plate 19 respectively has a retaining to pull 21, when Weight plate group 17,19 are upwards promoted by the cabinet door, oppositely drop to place, location 22, time Weight plate 19 is hung on this locating wheel 23 to guide groove 18 appearances with baffle plate 21, then cabinet door disequilibrium attitude is the light state in preceding heavy back.After the operator lets go, produce and to return the function of closing automatically, upwards take up time Weight plate with main Weight plate once again, the cabinet door only can and all can be located to the home place of closing the door thus automatically by semi-open and be set motionlessly to locating 22 places.If will reach the installation site that is provided with of opening fully, can be provided with catch in cabinet 10 appropriate positions of complete opening, to catch on the bottom of cabinet door 12, prevent that cabinet Men Zaixiang from descending, and conveniently carries out the setting that swings in of instrument and medicine.
