Detailed Description

The technical solution of the present patent will be described in further detail with reference to the following embodiments.

Example 1

Referring to fig. 1-3, the present embodiment provides a metal door opening device, which includes a base 1 and a clamping mechanism; the base 1 is provided with a clamping mechanism for clamping the metal door; the clamping mechanism comprises a clamping plate 2, a movable plate 3, a fixed rod 4, a toothed bar 5, a driven rotating shaft 6 and a driven lower gear 7; a plurality of fixed rods 4 are fixed inside the base 1, and movable plates 3 are symmetrically arranged at two ends of the fixed rods 4 in a sliding manner; clamping plates 2 for clamping the metal door are fixed on the two movable plates 3, and toothed bars 5 are symmetrically fixed on the lower ends of the two movable plates 3; a driven rotating shaft 6 is rotatably arranged on the base 1 positioned at the central parts of the two toothed bars 5, and a driven lower gear 7 which is mutually meshed with the two toothed bars 5 is fixed on the driven rotating shaft 6; the driving mechanism for driving the driven rotating shaft 6 to rotate is arranged in the base 1; set up like this, when actuating mechanism drive driven spindle 6 rotates to drive driven gear 7 down and rotate, thereby drive two ratchets 5 motions, thereby drive two fly leaf 3 and be close to and keep away from, thereby can be convenient for adjust the distance between two clamp plates 2, so that satisfy the demand of not equidimension metal door.

The driving mechanism comprises a driven upper gear 8, a driving gear 9, a rotating handle 10 and a driving rotating shaft 11; a driven upper gear 8 is fixed at the upper end of the driven rotating shaft 6; a driving gear 9 engaged with the driven upper gear 8 is rotatably arranged on the base 1 through a driving rotating shaft 11, the diameter of the driving gear 9 is larger than that of the driven upper gear 8, and a rotating handle 10 convenient for a worker to rotate is arranged on the driving gear 9; set up like this, when the staff rotates rotation handle 10 to drive driving gear 9 and rotate, because the diameter of driving gear 9 is greater than driven upper gear 8's diameter, thereby driven upper gear 8 rotates, thereby drives driven rotating shaft 6 and rotates, and the staff is at the rotation in-process comparatively laborsaving.

In order to prevent the metal door from falling off due to the reverse motion of the two clamping plates 2 in the hole opening process, a limiting mechanism for preventing the driven rotating shaft 6 from reversing is further arranged on the base 1; the limiting mechanism comprises a ratchet wheel 12, a rotating rod 13, an L-shaped fixing rod 14 and a limiting spring 15; a ratchet wheel 12 is fixed on the driven rotating shaft 6; a rotating rod 13 matched with the ratchet wheel 12 is rotatably arranged on the base 1; an L-shaped fixing rod 14 for limiting the rotating rod 13 to rotate anticlockwise is further fixed on the base 1, and the L-shaped fixing rod 14 is connected with the rotating rod 13 through a limiting spring 15; with such an arrangement, the ratchet 12 can be restricted from rotating clockwise by the cooperation of the ratchet 12, the rotating rod 13, the L-shaped fixing rod 14 and the limiting spring 15, so that the driven rotating shaft 6 is restricted from rotating clockwise, and the two clamping plates 2 can be restricted from being far away.
