The specific embodiment

Provide the utility model preferred embodiment below in conjunction with accompanying drawing, to describe the technical solution of the utility model in detail.

Fig. 1 is the structural representation of the utility model normal operation, Fig. 2 is the birds-eye view of Fig. 1, referring to Fig. 1 and 2, the utility model comprises lock body 100, lockhole 200, indicator lamp 300 and safety door 400, first spring 401 and second spring 402 of double deformation are installed on the safety door 400, the stiffness coefficient of first spring 401 is greater than the stiffness coefficient or second spring 402 of second spring 402, and the cross section of safety door 400 is a rhombus.

Novel subway anti-pinch safety door is invented in order to eliminate similar potential safety hazard, and the difference of novel subway anti-pinch safety door and common subway safe door is: 1, the seam of Men Yumen utilizes the deformable principle of rhombus, is designed to part rhombus door body; 2, can open certain angle to the platform direction in the rhombus door body portion of whole door, inwardly interior is then not all right; 3, assign close an instruction after, subway train door and compartment doorframe are provided with safety pin, the situation of closing of opposite house is confirmed, if the green light that door is closed on the compartment doorframe then fully lights, and safety pin guarantees the locking state of door in the vehicle operating process, certain fan door was hindered if door had not both been closed wherein fully, then the lockhole vital circuit loop that can't insert on the respective doors of safety pin can not be connected, be designated as red light, expression is closed the door unusual, and prompting chaufeur and platform train person restart train after need getting rid of unusually.

The subway anti-pinch safety door principle of work that the utility model provides is as follows, and after train driver was assigned the instruction of closing the door, the anti-pinch safety door was closed, and the amber light flicker is closed the door with indication platform passenger train in the closed procedure of pass.If situation is normally closed the door without hindrance, then the anti-pinch safety door should be in buttoned-up status, two safety pins in top, compartment this moment fall simultaneously, are inserted the lockhole on two fan anti-pinch safety door tops respectively, and this moment, two lockhole internal circuits were connected, form series loop, as shown in Figure 1, compartment green safety lamp will light, and the prompting train driver can start train, safety lock is in closed condition all the time in train operation, door can't be opened during the assurance train operation; When door is closed if abnormal condition take place, promptly as long as wherein Yishanmen is hindered, do not close fully, then the safety pin of compartment doorframe falls and can not enter lockhole on the respective doors, and because of the circuit layout of two safety locks be series connected, then do not close fully as long as also have one, vital circuit all will be for opening circuit, and this moment indicator lamp blinking red lamp and warning reminds train driver to close the door unusually, should open door and close the door again and remind the platform staff to check unusually, avoid accident; Guaranteeing that door is not if close train driver fully and can both indicate according to safety light, chaufeur does not start under the big safe prerequisite of train, the passenger that also considered to prevent in the design of door entering is crushed novel subway anti-pinch safety, and prevent that characteristics that the passenger utilizes the anti-pinch safety door can not be crushed from deliberately clamp-oning the bad phenomenon in compartment by force, its principle of work is as follows: the cause that is designed to rhombus when the passenger is pressed from both sides owing to a part of holding in front of the door, rhombus door body portion sends deformation in the moment that contacts encumbrance, then personnel only have the extruding sense but can't damage body part at this moment, shown in Fig. 3 and 4, if encumbrance is excessive, as illustrated in Figures 5 and 6, this moment, the second heavily deformation took place in door, the rhombus door body of not only original deformation but also past again platform direction rotate certain angle, make opening become bigger, here to emphasize a bit, the rhombus door body portion of anti-pinch safety door can only integral body outwards both the platform direction produce subtended angle, inwardly be that direction is then not all right in the compartment, promptly end on the plane that inwardly arrives normal door at most.For special extreme case, if the opening size of this moment does not still satisfy the size of encumbrance, as: run into three people one and come at closing time and enter simultaneously, this moment is because the buffering of twice deformation of anti-pinch safety door, the subconscious extruding that can resist door, the people just is not easy injured after subconscious defence is arranged, in addition through twice deformation the door body, be to contact clipped object with the clipped object contact site with the inclined-plane, what clipped object was stressed is face rather than line, thereby reduced the pressure of plane of action greatly, can not damage personnel.In addition for preventing the characteristics that a few passengers utilizes the anti-pinch safety door can not be crushed, after seeing the instruction of closing the door, the still generation of deliberately clamp-oning the bad phenomenon in compartment by force, the anti-pinch safety door is to consider so in design: it is to continue to clamp-on in the compartment or withdraw from the compartment that personnel are pressed from both sides that the descendant can select, get back to platform, if by the folder personnel selection the former, mentioning a few passengers both utilizes these characteristics of safety door deliberately to clamp-on by force, this moment the anti-pinch safety door since during design monoblock rhombus door body portion can only be outwards both the platform direction produce subtended angle, and inside subtended angle can only be got back to the plane of door at most, therefore rhombus door body portion can reduce because of the power subtended angle that clipped object is clamp-oned to the compartment, and the rhombus part also can get flat because of inside power deformation, both the opening of door can reduce thereupon at this moment, stoped caught object to enter the compartment, thereby prevented the uncivil generation of behavior by bus, if to clipped object outside power subtended angle be increased select outwards promptly get back to platform then whole rhombus door body portion by the folder personnel this moment, opening also will increase, then clipped object is withdrawed from smoothly, this moment, the anti-pinch safety door was because elastic hinge common on the market is equipped with in design, elastic reaction by hinge, the normal shape of door will be recovered, door is able to close fully once more, the safety pin in compartment is inserted the pin clamp on the security protection folder safety door at this moment, vital circuit forms C/LOOP, green light lights, the expression door is closed again fully, sees that the chaufeur of green light indication can start train this moment.If being pressed from both sides because of extraordinary circumstances, personnel can't break away from voluntarily or the clipped object shape is special can't to be removed, though this moment, the compartment safety pin fell, but because of Yishanmen is not wherein closed fully, cause latch can't insert pin hole and therefore still be the blinking red lamp that opens circuit, this moment, chaufeur should reopen car door, again close the door after a period of time, goalkeeper closes the demonstration green light fully if foreign matter is got rid of then when opening the door, if foreign matter is not got rid of yet, then repeat control step, this moment, the platform personnel should assist to get rid of unusually, after foreign matter confirms that eliminating anti-pinch safety door is closed fully, green indicating lamp lights, and chaufeur just can start train.
