Summary of the invention
Technical problem to be solved in the utility model is the defect overcoming prior art, and provide a kind of shield door retaining mechanism, it can not only facilitate the locking of doorframe and door leaf, and reduces its operation noise.
In order to solve the problems of the technologies described above, the technical solution of the utility model is: a kind of shield door retaining mechanism, it comprises driving mechanism, locking drive connecting rod, lock passive connecting rod, locking member, door leaf pull bar, locking transverse axis and the doorframe angled-lift splits being arranged on the door leaf fixed block on door leaf and being arranged on doorframe, driving mechanism is connected to drive it to rotate around one end with locking drive connecting rod, the one end of locking passive connecting rod is hinged with locking drive connecting rod, the other end and the locking member of locking passive connecting rod are hinged, locking member is arranged on door leaf pull bar, locking transverse axis is arranged on door leaf pull bar, door leaf pull bar can axially movably be arranged on door leaf, one end of locking transverse axis is arranged on door leaf fixed block, the other end is sliding to be fitted in the oblique chute of doorframe angled-lift splits.
Further provide a kind of concrete structure of driving mechanism its function driving locking drive connecting rod to rotate around its one end can be realized, described driving mechanism comprises force piece and worm type of reduction gearing, force piece is connected with the power shaft of worm type of reduction gearing, and described locking drive connecting rod is sleeved on the output shaft of worm type of reduction gearing.
Further in order to enable driving mechanism no matter whether break down dead electricity all can both drive the action of locking drive connecting rod, force piece comprises reducing motor, helical gear steering gear and manual handle, and manual handle and reducing motor and helical gear steering gear be selective to be connected reducing motor when obtaining electric with convenient reducing motor and to drive helical gear steering gear work and manual handle drives helical gear steering gear work when reducing motor dead electricity.
Further in order to make the utility model structure not affect presentation quality, this shield door retaining mechanism is arranged in door leaf case.
After have employed technique scheme, driving mechanism (reducing motor or manual handle drive worm type of reduction gearing work) drives locking drive connecting rod and locks passive connecting rod work, thus drive door leaf pull bar to move axially, locking transverse axis contract is entered the doorframe angled-lift splits on doorframe, door leaf cuts out the most at last; Helical gear steering gear be mainly used in when electrically or machinery breaks down time directly drive worm type of reduction gearing work by direct for manual handle insertion groove, carry out switch gate.
Accompanying drawing explanation
Fig. 1 is the structural representation of shield door retaining mechanism of the present utility model;
Fig. 2 is the top view of Fig. 1;
Fig. 3 is the structural representation of doorframe angled-lift splits of the present utility model.
Detailed description of the invention
In order to make content of the present utility model more easily be clearly understood, below according to specific embodiment also by reference to the accompanying drawings, the utility model is described in further detail.
As shown in Figures 1 to 3, a kind of shield door retaining mechanism, it comprises driving mechanism, locking drive connecting rod 1, lock passive connecting rod 2, locking member 3, door leaf pull bar 4, locking transverse axis 5 and the doorframe angled-lift splits 7 being arranged on the door leaf fixed block 6 on door leaf and being arranged on doorframe, driving mechanism is connected to drive it to rotate around one end with locking drive connecting rod 1, the one end of locking passive connecting rod 2 is hinged with locking drive connecting rod 1, the other end and the locking member 3 of locking passive connecting rod 2 are hinged, locking member 3 is arranged on door leaf pull bar 4, locking transverse axis 5 is arranged on door leaf pull bar 4, door leaf pull bar 4 can axially movably be arranged on door leaf, one end of locking transverse axis 5 is arranged on door leaf fixed block 6, the other end is sliding to be fitted in the oblique chute of doorframe angled-lift splits 7.
As shown in Figure 1, driving mechanism comprises force piece and worm type of reduction gearing 8, and force piece is connected with the power shaft of worm type of reduction gearing 8, and locking drive connecting rod 1 is sleeved on the output shaft of worm type of reduction gearing 8.
No matter whether breaking down dead electricity all can both drive the action of locking drive connecting rod 1 to enable driving mechanism, as shown in Figure 1, described force piece comprises reducing motor 9, helical gear steering gear 10 and manual handle 11, manual handle 11 and reducing motor 9 and helical gear steering gear 10 be selective be connected with convenient reducing motor 9 electric time reducing motor 9 drive helical gear steering gear 10 to work and work as reducing motor 9 dead electricity time manual handle 11 drive helical gear steering gear 10 to work.
In order to make this structure not affect presentation quality, shield door retaining mechanism is arranged in door leaf case.
Operating principle of the present utility model is as follows:
Reducing motor 9 is by the electric drive axle of helical gear commutator 10, drive the power shaft of worm type of reduction gearing 8, rotate through worm gear reducer rear drive locking drive connecting rod 1, locking drive connecting rod 1 and the passive connecting rod 2 of locking form a crank-link mechanism, locking drive connecting rod 1 convert rotational motion be moving up and down of door leaf pull bar 4, moving up and down of door leaf pull bar 4 drives locking transverse axis 5 to move up and down, because inclined-plane produces the tangential motion vertical with door leaf pull bar 4 direction of motion when locking transverse axis 5 moves in the oblique chute 7-1 of doorframe angled-lift splits 7, thus produce locking stroke, door leaf is locked.When losing electric power, by inserting the rotatable handle of manual handle 11, the electric drive axle of helical gear commutator 10 is driven to rotate by orthogonal screw gear pair, worm type of reduction gearing 8 is driven to do crank and connecting rod movement, do the action of switch gate, big retarding ratio can being realized by worm type of reduction gearing 8, ensureing coupling mechanism force when increasing the rotatable handle number of turns.Reducing motor uses gear reduction unit, not strap brake, not self-locking during dead electricity.
Above-described specific embodiment; technical problem, technical scheme and beneficial effect that the utility model solves are further described; be understood that; the foregoing is only specific embodiment of the utility model; be not limited to the utility model; all within spirit of the present utility model and principle, any amendment made, equivalent replacement, improvement etc., all should be included within protection domain of the present utility model.
