Specific embodiment
To make the objectives, technical solutions and advantages of the present invention clearer, With reference to embodiment
And referring to attached drawing, the utility model is further described.It should be understood that these descriptions are merely illustrative, and do not really want
Limit the scope of the utility model.In addition, in the following description, descriptions of well-known structures and technologies are omitted, to avoid not
Necessarily obscure the concept of the utility model.
As shown in Figs 1-4, the utility model proposes a kind of elevator door blocking device, including the first hanging plate 1, first hangs
The front surface of plate 1 is symmetrically installed with the second hanging plate 2 and fixed frame 5, side apical lateral wall of second hanging plate 2 close to fixed frame 5
First contact 3 is installed, the second hanging plate 2 is equipped with fixing seat 4, the front surface rotation of fixed frame 5 close to the lower section of the first contact 3
It is connected with latch hook 6, fixed frame 5 is equipped with follow block 7, the one end of follow block 7 far from fixed frame 5 close to the side bottom end of the second hanging plate 2
Upper surface is fixedly connected with support plate 8, and the bottom surface of support plate 8 is fixedly connected with the first spring 9, the separate support plate 8 of follow block 7
One end lateral wall is equipped with casing 13, is equipped with second spring 14 in casing 13, and second spring 14 is fixedly connected with follow block 7, and second
Spring 14 is fixedly connected with fixed plate 15 far from one end of casing 13；
The upper surface of fixing seat 4 offers the through slot 10 for fixing latch hook 6, and 10 inner sidewall of through slot is equipped with fixed link
11, the lateral wall of fixed link 11 is rotatably connected to idler wheel 12.
In the utility model, follow block 7 is fixed to by the outer of fixed frame 5 by casing 13, second spring 14 and fixed plate 15
Side wall, because support plate 8 is L font, when latch hook 6 is contacted with fixing seat 4, support plate 8 is contacted with latch hook 6, is risen by support plate 8
To the effect of support latch hook 6, and the elastic reaction of the first spring 9 is cooperated to slow down the impact force for carrying out latch nook 6, and disperses impact forces
To the second spring 14 of follow block 7, impact force is weakened again, reduces the impact force for being finally transferred to fixed plate 15 and fixed frame 5,
And then reduce active force of the latch hook 6 directly to follow block 7, have the function that protect follow block 7, extends the service life of follow block 7, work as lock
When hook 6 is caught in through slot 10, the idler wheel 12 in fixed link 11 not only avoids latch hook 6 from directly contacting with fixing seat 4, plays isolation
Effect, since idler wheel 12 is able to rotate in itself, and can assist for latch hook 6 being directed in through slot 10, auxiliary equally when latch hook 6 produces
It helps it to be detached from through slot 10, slows down latch hook 6 and fixing seat 4 generates the case where damaging, the clamping improved between latch hook 6 and through slot 10 is quasi-
True property.
As Figure 1 and Figure 4, support plate 8 is L font, and when latch hook 6 is contacted with fixing seat 4, support plate 8 connects with latch hook 6
Touching.
Both it should be noted that the support plate 8 of L font meets shape of the latch hook 6 far from the one end for determining croquet 61, improve
Between compactness, be conducive to stablize.
As shown in Figure 1, follow block 7 is fixedly connected by fixed plate 15 with fixed frame 5, and casing 13 is hollow structure.
It should be noted that follow block 7 and second spring 14 are fixed to the lateral wall of fixed frame 5 by fixed plate 15, the
Two springs 14 play intermediation, and the lateral wall of second spring 14 is set in convenient for casing 13.
As shown in Figure 1, the quantity of the first spring 9 is two, two the first springs 9 are symmetrically distributed in the bottom surface of support plate 8.
It should be noted that the elastic acting force phase that two the first springs 9 are subject to the upper surface both ends of support plate 8
Together, it is conducive to synchronous support plate 8 and synchronizes shaking.
As shown in Fig. 2, fixed link 11 and the quantity of idler wheel 12 are two, two fixed links 11 and two idler wheels 12 symmetrically divide
Cloth is in 10 inside of through slot.
It should be noted that the motive force that two idler wheels 12 are subject to the two sides of latch hook 6 is identical, latch hook 6 is improved from logical
The smooth degree being detached from slot 10.
As shown in Figure 1, latch hook 6 is equipped with far from one end front surface of the first contact 3 determines croquet 61, the outside of croquet 61 is determined
Wall is fixed with torsional spring 62, and latch hook 6 is equipped with touch base 63 far from one end upper surface for determining croquet 61.
It may make latch hook 6 fixed and 5 surface of fixed frame it should be noted that determining croquet 61, torsional spring 62 generates torsional forces band
Moveable lock hook 6 resets, and for touch base 63 for cooperating the first contact 3 to use, elevator door is closed in effect.
The working principle and process for using of the utility model: the first contact when elevator door is closed, on the second hanging plate 2
3 with 63 contact closure of touch base, determine 5 surface of fixed frame that croquet 61 may make latch hook 6 fixed with the first hanging plate 1, in the production of torsional spring 62
Under the action of raw torque force-fitting latch hook 6, so that latch hook 6 and fixing seat 4 are locked, door is closed, and passes through casing 13, the second bullet
Follow block 7 is fixed to the lateral wall of fixed frame 5 by spring 14 and fixed plate 15, because support plate 8 is L font, when latch hook 6 and fixing seat 4
When contact, support plate 8 is contacted with latch hook 6, plays the role of supporting latch hook 6 by support plate 8, and cooperate the bullet of the first spring 9
Property effect slow down the impact force for carrying out latch nook 6, and at disperses impact forces to the second spring 14 of follow block 7, weaken impact force again,
Reduce the impact force for being finally transferred to fixed plate 15 and fixed frame 5, and then reduce active force of the latch hook 6 directly to follow block 7, reaches
The effect of follow block 7 is protected, the service life of follow block 7, the idler wheel 12 when latch hook 6 is caught in through slot 10, in fixed link 11 are extended
Not only avoid latch hook 6 from directly contacting with fixing seat 4, play the role of isolation, since idler wheel 12 is able to rotate in itself, and can assist by
Latch hook 6 is directed in through slot 10, equally when latch hook 6 produces, it is assisted to be detached from through slot 10, slows down latch hook 6 and fixing seat 4 generates
The case where damage, improves the clamping accuracy between latch hook 6 and through slot 10, and touch base 63 is for cooperating the first contact 3 to use, effect
Close elevator door.
It should be understood that the above-mentioned specific embodiment of the utility model is used only for exemplary illustration or explains this reality
With novel principle, without constituting limitations of the present invention.Therefore, in the spirit and scope without departing from the utility model
In the case of any modification, equivalent substitution, improvement and etc. done, should be included within the scope of protection of this utility model.In addition,
The appended claims for the utility model are intended to cover to fall into attached claim scope and boundary or this range and boundary
Whole change and modification in equivalent form.
