Control loop, the motor control loop its unlatching and closure that the clamshell doors are controlled by controlling the positive and negative rotation of motor, institute
Stating clamshell doors includes interior door body and outer door body, and the outer door body is socketed in the interior door body in a manner of elastic telescopic；
Travel switch is additionally provided in the interior door body, the travel switch includes a normally opened contact, when the outer door body quilt
When compression, the travel switch is pressed；
Power-off delay relay is equipped in the motor control loop, the power-off delay relay includes a normally-closed contact
And a normally opened contact, normally-closed contact with make the motor be closed the clamshell doors electric switch is connected, normally opened contact
With make the motor open the clamshell doors electric switch it is in parallel, the normally opened contact of the travel switch is as the power-off
Time-delay relay obtains electric switch.
Further, parallel is furnished with several linear bearings along the vertical direction in the interior door body, in the outer door body
Several linear guides for corresponding to linear bearing sliding are fixed with, are arranged with spring, the bullet in the linear guide
For spring between the linear bearing and the fixing end of the linear guide, the linear guide stretches out the cunning of the linear bearing
It moves on end and is connected with circlip.
Further, the end of the sliding-end of the linear guide is in bulb shape.
Further, towards closing direction, bumper rubber is provided in the outer door body.
After adopting the above technical scheme, the utility model compared with the background art, has the advantages that
1, the utility model improves clamshell doors, and outer door body is socketed in the interior door body in a manner of elastic telescopic
On so that passenger when being clamped by protective door there are the spatial margin of limb activity, prevent from being pinched；Meanwhile it can make
Motor operating is obtained to open clamshell doors, so that passenger gets rid of poverty, and reaches the setting time of delay cut-off relay in the opening time
When, it is closed again.
2, bumper rubber is provided in the outer door body of the utility model, there are two effects herein for the bumper rubber: firstly,
It can further decrease injury of the clamshell doors to passenger；Secondly, its effect that can further promote isolation cold air.
Detailed description of the invention
Fig. 1 is the utility model nuclear structure schematic diagram；
Fig. 2 is the utility model core circuit figure.
Specific embodiment
In order to make the purpose of the utility model, technical solutions and advantages more clearly understood, below in conjunction with attached drawing and implementation
Example, the present invention will be further described in detail.It should be appreciated that specific embodiment described herein is only used to explain
The utility model is not used to limit the utility model.
In the present invention it should be noted that term " on " "lower" " left side " " right side " "vertical" "horizontal" "inner" "outside" etc.
It is to be based on the orientation or positional relationship shown in the drawings, it is only for convenient for description the utility model and simplify description, without
It is that the device of indication or suggestion the utility model or element must have a particular orientation, therefore should not be understood as practical new to this
The limitation of type.
Embodiment
It please refers to shown in Fig. 1, the utility model discloses a kind of underground space protective doors, including clamshell doors and driving mechanism
(not shown).In the driving mechanism include motor and motor control loop, the motor control loop its pass through control
The positive and negative rotation of motor controls the unlatching and closure of the clamshell doors.
The clamshell doors include interior door body 1 and outer door body 2, and the outer door body 2 is socketed in described in a manner of elastic telescopic
In interior door body 1.In the present embodiment, by being realized with flowering structure: parallel is furnished with several along the vertical direction in the interior door body 1
Linear bearing 11 is fixed with several linear guides 21 for corresponding to the linear bearing 11 sliding in the outer door body 2, described
Be arranged with spring 22 in linear guide, the spring 22 be located at the linear bearing 11 and the linear guide 21 fixing end it
Between, the linear guide 21, which is stretched out on the sliding-end of the linear bearing 11, is connected with circlip 23.
Towards closing direction, bumper rubber 24 is provided in the outer door body 2.
Travel switch 12 is additionally provided in the interior door body 1, the travel switch 12 includes a normally opened contact, when the external door
When body 2 is compressed, the travel switch 12 is pressed.
Since the latching circuit of the positive and negative rotation circuit of motor, interlock circuit and relay is the routine of this field, herein not
It repeats, the core circuit figure for only winning the utility model involved in the motor control loop is explained.
It please refers to shown in Fig. 2, it is assumed that motor is closed clamshell doors when rotating forward, then the normally opened contact KA1 of intermediate relay
Be in the motor control loop for control motor rotating forward electric switch, and it keeps after intermediate relay KA1 obtains electricity
Closed state, KM1 are the main relays for controlling motor rotating forward；The normally opened contact KA2 of intermediate relay is the motor control
For controlling the electric switch that obtains of motor reversal in circuit processed, KM2 is in the motor control loop for controlling motor reversal
Main relay；KT is powered off time-delay relay comprising a normally-closed contact and a normally opened contact and make described normally-closed contact
Motor closure the electric switch normally opened contact KA1 of intermediate relay (herein be) series connection, normally opened contact and make the electricity
Machine open the clamshell doors electric switch (the i.e. normally opened contact KA2 of intermediate relay herein) parallel connection, the travel switch 12
Normally opened contact SB as the power-off delay relay KT electric switch.
In this way, outer door body 2 is compressed first when someone or object are clamped by clamshell doors, prevent to people or gripped object
It damages；Simultaneously as outer door body 2 is compressed, travel switch 12 is pressed at the bulb end of linear guide 21, then SB's is normally opened
Contact closure, the power-off delay relay KT obtain electric, then the normally-closed contact closure of KT, normally opened contact disconnect, thus make it is main after
Electric appliance KM1 power loss, main relay KM2 obtain electric, and motor reversal opens clamshell doors.
After people or clamping object detach, due to the effect of spring 22,2 return of outline border door, the bulb end of linear guide 21 from
The press-side of travel switch 12 slips, and travel switch 12 resets, then power-off delay relay KT power loss, when reaching setting time
When (the present embodiment 2S), each contact return of power-off delay relay, since the normally opened contact KA1 holding of intermediate relay is closed
It closes, so motor rotates forward again, is closed the clamshell doors.
The preferable specific embodiment of the above, only the utility model, but the protection scope of the utility model is not
It is confined to this, anyone skilled in the art within the technical scope disclosed by the utility model, can readily occur in
Change or replacement, should be covered within the scope of the utility model.Therefore, the protection scope of the utility model should
It is subject to the protection scope in claims.
