Abstract
The utility model discloses an elevator car ventilation unit, ventilation unit is including seting up skylight and the controlling means in the sedan -chair top outside, hinge and sedan -chair top swing joint are passed through to the rear end in skylight, controlling means comprises connecting piece, guide arm, compression spring and electro -magnet, the connecting piece is the zigzag structure and the rectangle through -hole has been seted up on its upper portion to the lower part fixed connection of connecting piece is at the front end in skylight, the lower extreme of guide arm passes the rectangle through -hole and sedan -chair top fixed connection on connecting piece upper portion, spring pocket connects on the guide arm between sedan -chair top and connecting piece, electro -magnet fixed mounting sedan -chair top, still be provided with the telescopic link that is used for pushing down the skylight on the electro -magnet. The device adopts electro -magnet fixed skylight, and the spring provides the power that opened in the skylight, and the sensitivity of safety action can effectively realize taking a breath in the car to the device simple structure, when the elevator had a power failure, the device provided sufficient air, guaranteed passenger's life safety.
Description
technical field:
The utility model belongs to elevator technology field, especially relates to a kind of elevator cage ventilating device.
background technology:
Along with the high stratification of building, elevator also achieves high speed.Because elevator speed is too fast, car will ensure good air-tightness, and passenger can not be excessive due to noise, and produce sense of discomfort, at this moment car can adopt exhaust fan to take a breath.When elevator power failure, exhaust fan stop working, supports not enough in car, passenger survival is difficult to safely ensure.
summary of the invention:
Technical problem to be solved in the utility model is: provide a kind of for the device for ventilating in elevator.
In order to solve the problems of the technologies described above, the utility model is achieved through the following technical solutions: a kind of elevator cage ventilating device, described drafting apparatus comprises and is opened in skylight outside sedan-chair top and control setup, the rear end in described skylight is flexibly connected with sedan-chair top by hinge, described control setup is by attaching parts, guide rod, Compress Spring and electromagnet composition, described attaching parts is zigzag structure and its top offers rectangular through-hole, and the bottom of attaching parts is fixedly connected on the front end in skylight, the lower end of described guide rod is fixedly connected with sedan-chair top through the rectangular through-hole on attaching parts top, described Compress Spring is socketed on the guide rod between sedan-chair top and attaching parts, on described electromagnet fixed installation sedan-chair top, described electromagnet is also provided with the expansion link for pushing down skylight.
As preferably, described sedan-chair top is also provided with the switch for controlling electromagnet opening and closing.
As preferably, described guide rod upper end is connected with locknut, and the guide rod between described locknut and attaching parts is socketed with recoil spring, and the elastic force of described recoil spring is less than the elastic force of Compress Spring.
As preferably, the length of the rectangular through-hole that described attaching parts top is offered is the length of 2 ~ 4 guide rod diameters.
Compared with prior art, usefulness of the present utility model is: this device adopts electromagnet fixed skylight, the power that spring provides skylight to open, the sensitieness of safety action, effectively can realize the ventilation in car, and this apparatus structure is simple, when elevator power failure, this device provides sufficient air, ensures the life security of passenger.
accompanying drawing illustrates:
Below in conjunction with accompanying drawing, the utility model is further illustrated.
Fig. 1 is structural representation of the present utility model.
In figure: 1, sedan-chair top; 2, skylight; 3, attaching parts; 4, guide rod; 5, Compress Spring; 6, electromagnet; 61, expansion link; 7, switch; 8, locknut; 9, recoil spring; 10, hinge.
detailed description of the invention:
Below in conjunction with the drawings and the specific embodiments, the utility model is described in detail:
A kind of elevator cage ventilating device as shown in Figure 1, described drafting apparatus comprises and is opened in skylight 2 outside sedan-chair top 1 and control setup, the rear end in described skylight 2 is flexibly connected with sedan-chair top 1 by hinge 10, described control setup is by attaching parts 3, guide rod 4, Compress Spring 5 and electromagnet 6 form, described attaching parts 3 is for zigzag structure and its top offers rectangular through-hole, and the bottom of attaching parts 3 is fixedly connected on the front end in skylight 2, the lower end of described guide rod 4 is fixedly connected with sedan-chair top 1 through the rectangular through-hole on attaching parts 3 top, described Compress Spring 5 is socketed on the guide rod 4 between sedan-chair top 1 and attaching parts 3, described electromagnet 6 fixedly mounts on sedan-chair top 1, described electromagnet 6 is also provided with the expansion link 61 for pushing down skylight 2.
For the ease of controlling the break-make of electromagnet 6 circuit, described sedan-chair top 1 is also provided with the switch 7 for controlling electromagnet 6 opening and closing.
In order to the impact concussion caused when being opened in low skylight 2, described guide rod 4 upper end is connected with locknut 8, and the guide rod 4 between described locknut 8 and attaching parts 3 is socketed with recoil spring 9, and the elastic force of described recoil spring 9 is less than the elastic force of Compress Spring 5.
The length of the rectangular through-hole that described attaching parts 3 top is offered is the length of 2 ~ 4 guide rod 4 diameters, adopt this structure, in car can air ventilation, skylight 2 can only opening and closing within the specific limits, avoids the situation that skylight 2 folding is excessive or too small.
It is emphasized that: be only preferred embodiment of the present utility model above, not any pro forma restriction is done to the utility model, every above embodiment is done according to technical spirit of the present utility model any simple modification, equivalent variations and modification, all still belong in the scope of technical solutions of the utility model.
