Fig. 2 is the structural representation that in Fig. 1, door lock is in opening.
Fig. 3 is the structural representation of the second embodiment of door-opened elevator lock construction of the present invention.
Fig. 4 is the structural representation of the third embodiment of door-opened elevator lock construction of the present invention.
Detailed description of the invention
The present invention is described in further detail for the embodiment provided below in conjunction with accompanying drawing.
As depicted in figs. 1 and 2, as the first embodiment of the present invention, this door-opened elevator lock construction comprises a layer door lock hook 1, layer door lock 2 and door latch spring 3, and described layer door lock 2 front end and layer door lock hook 1 hook, described door latch spring 3 is for the reset of layer door lock 2.
This door-opened elevator lock construction further comprises door lock connection bracket 4, pull bar upper bracket 5, pull bar 6, pull bar lower bracket 7, pouring weight 8, pouring weight adapter plate 9 and layer door triangulation chain 10.
The upper end of described door lock connection bracket 4 is fixedly connected with the tail end of layer door lock 2, and lower end is by the rotatable pivot joint of the first pivot 11 and pull bar upper bracket 5.Described pull bar 6 upper end is connected by adjustable screw with pull bar upper bracket 5, and lower end is connected by adjustable screw with pull bar lower bracket 7, by adjustable screw, freely up and down can adjust the position of pull bar 6.Rotatably be articulated in pouring weight adapter plate 9 by the second pivot 12 in the middle part of described pouring weight 8, described pouring weight adapter plate 9 is fixed on elevator door 13.Described pouring weight 8 one end is by the rotatable pivot joint of the 3rd pivot 14 and pull bar lower bracket 7, and the other end and layer door triangulation chain 10 close on and arrange and be struck according to the rotation of layer door triangulation chain 10.Large 10Nm ~ the 20Nm of described pouring weight 8 torque ratio pull bar 6 moment, for this reason, pouring weight 8 can be used for the weight of balancing pull rod 6, in state of nature, ensures that layer door lock 2 is in closure state.
Further, described door lock connection bracket 4, pull bar upper bracket 5, pull bar 6 and pull bar lower bracket 7 vertically set gradually, and described pouring weight 8 and layer door triangulation chain 10 are all arranged on the left side of pull bar lower bracket 7.This frame mode can the rational height of lower layer door triangulation chain, namely reduces the height of door lock.
Further, described pouring weight 8 is bending plate, it comprises horizontal part 81 and a bias portion 82, and described horizontal part 81 is by the rotatable pivot joint of the 3rd pivot 14 and pull bar lower bracket 7, and described bias portion 82 closes on layer door triangulation chain 10 and arranges and be struck according to the rotation of layer door triangulation chain 10.
When layer door triangulation chain 10 rotates, the bias portion 82 of pouring weight 8 is struck and rotates up, the horizontal part 81 of pouring weight 8 is rotated down according to lever principle, and drive pull bar lower bracket 7, pull bar 6, pull bar upper bracket 5, door lock connection bracket 4 and layer door lock 2 tail down action, make layer door lock 2 front end abscission layer door lock hook 1, layer door reaches opening.
As shown in Figure 3, as the second embodiment of the present invention, with the first embodiment difference be: described pull bar upper bracket 5 comprises vertical portion 51 and the portion anyhow 52 bent from this lower end, vertical portion 51 to the right, the lower end of described door lock connection bracket 4 is by the pivot joint rotatable with the vertical portion 51 of described pull bar upper bracket 5 of the first pivot 11, the upper end of described pull bar 6 is connected by adjustable screw with the portion anyhow 52 of described pull bar upper bracket 5, stagger between described door lock connection bracket 4 and pull bar 6 certain distance and being parallel to each other, described pouring weight 8 and layer door triangulation chain 10 are all arranged on the left side of pull bar lower bracket 7.In this frame mode, by changing the width value L of pull bar upper bracket 5, layer door triangulation chain 10 can change position in left and right; By changing the height value H of pull bar upper bracket 5, layer door triangulation chain 10 can change position up and down.
As shown in Figure 4, as the third embodiment of the present invention, with first, the second embodiment difference is: described pull bar upper bracket 5 comprises vertical portion 53 and the portion anyhow 54 bent from this lower end, vertical portion 53 left, the lower end of described door lock connection bracket 4 is by the pivot joint rotatable with the vertical portion 53 of described pull bar upper bracket 5 of the first pivot 11, the upper end of described pull bar 6 is connected by adjustable screw with the portion anyhow 54 of described pull bar upper bracket 5, stagger between described door lock connection bracket 4 and pull bar 6 certain distance and being parallel to each other, described pouring weight 8 and layer door triangulation chain 10 are all arranged on the right side of pull bar lower bracket 7.In this frame mode, by changing the width value L of pull bar upper bracket 5, layer door triangulation chain 10 can change position in left and right; By changing the height value H of pull bar upper bracket 5, layer door triangulation chain 10 can change position up and down.
As described above, be only preferred embodiment of the present invention, when not limiting scope of the invention process with this, the simple equivalence namely generally done according to the present patent application the scope of the claims and invention description content changes and modifies, and all still remains within the scope of the patent.
