Problems solved by technology

[0002] At present, in order to maximize the indoor space, the user has smaller and smaller requirements for the size of the hoistway of the home elevator, which makes it difficult to realize the design of the automatic door opener. It can only be designed in the form of manual door opening, but this design is no car inner door. Therefore, laws and regulations also have clear regulations on the speed of this type of elevator.
However, there are still hidden dangers of shearing and extrusion during elevator operation.

Embodiment Construction

[0024] Such as figure 1 Schematic diagram of the installation structure of the folding manual telescopic car door device; figure 2 As shown in the schematic diagram of the structure of the folding manual telescopic car door device, a folding manual telescopic car door device is used as a home elevator car door, and guide devices are installed above and below the entrance and exit of the car. Alloy or stainless steel material sheets are made into leaves 1, and the leaf leaves are connected by connecting shafts 2 to form a louvered folding door. Hollow safety glass 3 is embedded in the louvered folding door. The upper or lower end of the door is divided into an upper sliding wheel 4' and a lower sliding wheel 4, which cooperate with the upper guide device 5 fixed on the lintel 10 or the lower guide device 6 fixed on the bed platform 10, and the upper sliding wheel 4' is along the The upper guide device 5 slides, and the lower sliding wheel 4 slides along the lower guide devic...

Abstract

A folding type manual telescopic car door serves as a household lift car door. Guide devices are arranged at the upper side and the lower side of an inlet and outlet of a lift car, wherein strip-shaped aluminum alloy or stainless steel material sheets are made into leaves, a shutter folding door is formed by connecting the leaves through couplers, hollow-out safe glass is embedded into the shutter folding door, sliding wheels are at least arranged at the upper end and the lower end of the shutter folding door, the sliding wheels are matched with the upper guide device fixed to a door header and the lower guide device fixed to a bed table, the sliding wheels slide along the guide devices, one end of the shutter folding door is fixed to a side wall plate of the lift car through fixing bolts, the other side of the shutter folding door is provided with a handle favorable for closing the door and an electrical contact switch confirming that the door is closed in place, when the door is closed in place, a safety circuit of a lift is connected, and the lift can be operated. The folding type manual telescopic car door avoids the danger of shearing and extruding in operation of the lift car and is simple in structure, attractive in appearance, convenient to operate, safe, reliable, low in fault rate and capable of sufficiently saving space.

Description

technical field [0001] The invention relates to a folding manually telescopic car door device, which relates to an elevator car door device, and is especially suitable for home elevators. Background technique [0002] At present, in order to maximize the indoor space, users have smaller and smaller requirements for the size of the hoistway of the home elevator, which makes it difficult to realize the design of the automatic door opener. It can only be designed in the form of manual door opening, but this design is no car inner door. Therefore, laws and regulations also have clear regulations on the speed of this type of elevator. However, there are still hidden dangers of shearing and extrusion during elevator operation. [0003] In order to meet the needs of customers and solve the above problems, it is necessary to develop a folding manual retractable car door that prevents the elevator car from being cut and squeezed during operation. Contents of the invention [0004...
