The purpose of this utility model can also adopt following technical measures to solve:
As a kind of scheme more specifically, described torsion spring system adopts steel wire to be formed to the both sides winding by the middle part, and the curved steel wire that goes out one section U-shaped in its middle part forms described first group of conflict pin, and the steel wire two ends form described second group of conflict pin.
Described latch hook is tabular, its middle part is provided with connecting bore, two ends respectively corresponding door lock link plate and collision block are provided with fastener and round steel, round steel horizontally set, its two ends extend the latch hook outside, described lock takes the shape of the letter U, torsion spring and latch hook all are arranged on lock inboard and latch hook and are positioned at the torsion spring middle part, and bolt passes lock both sides, torsion spring and latch hook is connected connecting bore and is connected with nut.
Described latch hook both sides also are provided with middle spacing sleeve, and middle spacing sleeve is set between torsion spring and the bolt.
Described collision block is connected with cage by another bolt, and the round steel of the corresponding latch hook of collision block downside is provided with the dip plane.
The beneficial effects of the utility model are as follows:
Therefore (1) spring of this kind of mechanical interlock adopts special torsion spring, and torsion spring set can not come off in bolt, and mechanical interlock is safe and reliable, and easy for installation, accuracy of positioning is high, outward appearance is graceful;
(2) the latch hook rear end is welded with round steel, to increase the area of contact of itself and collision block, reduces wearing and tearing between the two.

The specific embodiment
Below in conjunction with drawings and Examples the utility model is further described.
Extremely shown in Figure 5 such as Fig. 1, this mechanical interlocking device for feeding door of lift cage, comprise latch hook 3, lock 7, elastic reset spare and the collision block 2 that is connected with cage 1, lock 7 is to be connected with the outer cage door frame 8 of elevator, outer cage door frame 8 is provided with feeding gate 5, feeding gate 5 is provided with the door lock link plate 4 with latch hook 3 snappings, described latch hook 3 rotates by bolt 6 and is arranged on the lock 7, elastic reset spare is torsion spring 9, torsion spring 9 is set in outside the bolt 6, and torsion spring is provided with two groups of conflict pin, wherein, first group of conflict pin 91 joins with latch hook 3, and second group of conflict pin 92 conflicted with lock 7 or outer cage door frame 8.
Described torsion spring 9 is to adopt steel wire to be formed to the both sides winding by the middle part, and the curved steel wire that goes out one section U-shaped in its middle part forms described first group of conflict pin 91, and the steel wire two ends form described second group of conflict pin 92.
Described latch hook 3 is tabular, its middle part is provided with connecting bore 33, two ends respectively corresponding door lock link plate 4 and collision block 2 are provided with fastener 32 and round steel 31, round steel 31 horizontally sets, its two ends extend latch hook 3 outsides, described lock 7 takes the shape of the letter U, torsion spring 9 and latch hook 3 all are arranged on lock 7 inboards and latch hook 3 is positioned at torsion spring 9 middle parts, and bolt 6 passes the connecting bore 33 of lock 7 both sides, torsion spring 9 being connected with latch hook and is connected with nut 12.Wherein, round steel 31 is welded and fixed with latch hook 3 and is integrated.
Described latch hook 3 both sides also are provided with middle spacing sleeve 11, and middle spacing sleeve 11 is set between torsion spring 9 and the bolt 6.
Described collision block 2 is connected with cage 1 by another bolt 10, and the round steel 31 of the corresponding latch hook 3 of collision block 2 downsides is provided with the dip plane.
Principle of work: in the whole working cycle, if the feeding gate of not opening cage then latch hook 3 without any action.When elevator craning cage 1 is positioned at bottom station, by the terminal round steel 31 that is installed in collision block 2 on the elevator craning cage 1 and down pushes down latch hook 3, overcome the torsion of torsion spring 9, make latch hook 3 leave door lock link plate 4 on the feeding gate 56, can up open feeding gate 5(feeding gate this moment is vertical upper and lower opening and closing).When cage 1 leaves bottom station, collision block 2 on the elevator craning cage 1 just leaves latch hook 3, latch hook 3 is under the twisting force of torsion spring 9, the fastener 32 of latch hook 3 just hooks the door lock link plate 4 on the feeding gate 5, therefore the cage feeding gate just can't upwardly open and open, play prevent that cage from leaving bottom stop after, feeding gate 5 is opened or artificial effects of opening automatically.In the whole interlocking process, because latch hook 3 ends have round steel 31, so frictionally damage is very little, and torsion spring 9 is through the centre of bolt 11, so torsion spring can Automatic-falling, improves reliability and the service life of interlock mechanism, the safety performance that raising equipment uses.
