Abstract
The utility model discloses a kind of mechanical type nudging device, comprise base, described base is provided with base plate, described base plate is connected with and is rotationally connected bar, described in be rotationally connected bar one end be connected with adapter shaft strut, the other end is connected with roller, described base plate and described being rotationally connected between bar are provided with extension spring, described extension spring is fixed on described base plate by spring joint pin, and be provided with roller lifting arm in the middle of described roller, described roller lifting arm is also connected with the support that puts in place.The utility model is a kind of mechanical type nudging device, overcomes a shortcoming that machine-operated door confining force is inadequate, a machine is put in place close the door more reliable.
Description
Technical field
The utility model relates to a kind of door closing device, is specifically related to a kind of mechanical type nudging device.
Background technology
At present, the door closing device of elevator has a lot, but more or less can there is the shortcoming that door office door confining force is inadequate, a machine is put in place close the door not comprehensive, make elevator there is potential safety hazard, and the utility model overcomes a shortcoming that machine-operated door confining force is inadequate, a machine is put in place and closes the door comprehensively, greatly reduce existing potential safety hazard, and use also more convenient.
Utility model content
The purpose of this utility model is to overcome prior art Problems existing, provides a kind of mechanical type nudging device.
For realizing above-mentioned technical purpose, reach above-mentioned technique effect, the utility model is achieved through the following technical solutions:
A kind of mechanical type nudging device, comprise base, described base is provided with base plate, described base plate is connected with and is rotationally connected bar, described in be rotationally connected bar one end be connected with adapter shaft strut, the other end is connected with roller, described base plate and described being rotationally connected between bar are provided with extension spring, described extension spring is fixed on described base plate by spring joint pin, and be provided with roller lifting arm in the middle of described roller, described roller lifting arm is also connected with the support that puts in place.
Further, described base and described base plate are fixed on the link plate of described device, are the fixed positions that described device is connected with link plate.
Further, described spring joint pin, is rotationally connected bar and extension spring forms a swinging structure by the action of spring elongation power.
Preferably, described spring joint pin has two.
Further, the support that puts in place described in is provided with groove.
The beneficial effects of the utility model:
The utility model is a kind of mechanical type nudging device, overcomes a shortcoming that machine-operated door confining force is inadequate, a machine is put in place close the door more reliable.
Accompanying drawing explanation
Fig. 1 is the structural representation of the utility model mechanical type nudging device.
Number in the figure illustrates: 1, base, 2, spring joint pin, 3, adapter shaft strut, 4, be rotationally connected bar, 5, roller lifting arm, 6, roller, 7, extension spring, 8, put in place support, 9, base plate.
Detailed description of the invention
Below with reference to the accompanying drawings and in conjunction with the embodiments, describe the utility model in detail.
With reference to shown in Fig. 1, a kind of mechanical type nudging device, comprise base 1, described base 1 is provided with base plate 9, described base plate 9 is connected with and is rotationally connected bar 4, described one end being rotationally connected bar 4 is connected with adapter shaft strut 3, the other end is connected with roller 6, described base plate 9 and described being rotationally connected between bar 4 are provided with extension spring 7, described extension spring 7 is fixed on described base plate 9 by spring joint pin 2, be provided with roller lifting arm 5 in the middle of described roller 6, described roller lifting arm 5 is also connected with the support 8 that puts in place.
Further, described base 1 and described base plate 9 are fixed on the link plate of described device, are the fixed positions that described device is connected with link plate.
Further, described spring joint pin 2, is rotationally connected bar 4 and forms a swinging structure by the action of spring elongation power with extension spring 9.
Preferably, described spring joint pin 2 has two.
Further, the support 8 that puts in place described in is provided with groove.
Principle of the present utility model:
When being about to put in place when closing the door, roller 6, near putting support 8 in place, enters the guide rail of the support 8 that puts in place, extension spring 7 pulls open has a pulling force afterwards to being rotationally connected bar 4, and make to be rotationally connected bar 4 action, roller 6 enters the groove of the support 8 that puts in place, door-closing in-place, is equivalent to a mechanical confining force of closing the door.
When door is motor-driven open the door time, base assembly is to left movement, and roller 6 exits the groove of the support 8 that puts in place, and to put in place support 8 until roller 6 departs from, door opening action completes.
The foregoing is only preferred embodiment of the present utility model, be not limited to the utility model, for a person skilled in the art, the utility model can have various modifications and variations.All within spirit of the present utility model and principle, any amendment done, equivalent replacement, improvement etc., all should be included within protection domain of the present utility model.
