Shaftless edge tangential-rotating door

Abstract

The invention discloses a shaftless edge tangential-rotating door, which relates to a rotating door without a door shaft. An upper rail 1 corresponds to a ground rail 7. The upper rail and the ground rail are respectively formed by two straight section parts which are respectively provided for the outer side of a door leaf 3 to move tangentially or for the inner side of the door leaf 3 to move horizontally, wherein the two straight section parts keep the identical included angles. The door leaf 3 moves horizontally and slides inwards simultaneously along the upper rail 1 and the ground rail 7, the opening method is unique, the structure is simple, the installation is convenient, the construction cost is low, the opening and the closing are flexible and labor-saving, the load bearing is balanced, the maintenance is facilitated, the structural deformation is avoided, the labor intensity is reduced, the time for installation and work is effectively reduced when the shaftless edge tangential-rotating door is used as a garage door, the civil engineering investment is saved, the wind resistance function is obvious, no external space is occupied, a vehicle can be caused to turn at the same time of leaving, the vehicle line haul hour is saved, and the shaftless edge tangential-rotating door is particularly suitable to be used for a firefighting and redeployment garage. In addition, according to the need, the shaftless edge tangential-rotating door can be additionally provided with an electric device, a remote control device and the functions of preventing thieves, breaking and bullets.

Description

Technical field: [0001] The invention relates to a revolving door without a door shaft, in particular to a revolving door without a shaft. Background technique: [0002] The traditional door adopts a shaft-type inner and outer swing, or track sliding translation, rotation, or up and down, left and right folding and other methods. As the Chinese patent application 92210275.9 left-handed sliding door with hinges, upper and lower tracks are arranged, and the door panels are connected by hinges. 96241839.0 push-pull mobile rolling door, the transmission mechanism includes a power reversing device, the main body of which is a pair of ratchets set in opposite directions, which are respectively driven and rotated by the transmission frame fixed to the transmission shaft. When one ratchet transmits power, the other One ratchet is idling, and the transmission mechanism also includes one to two sets of braking devices, which respectively brake the sprockets driven by the two ratchets...

AI Technical Summary

Problems solved by technology

[0003] Especially for large-scale building doors such as outdoor garages, it is required to be solid and durable, and to be convenient and flexible to operate. However, the aforementioned folding doors in the prior art are limited in their application due to their limited thermal insulation and impact resistance, while the track sliding translation doors need to be installed between the two sides of the door. A track with at least the same width is reserved on the side for parking the door leaf after the door is opened, so it cannot be implemented under many conditions; for a door leaf with a shaft door, a larger rotation radius and unobstructed ground and space are required during the opening process. Opening, and there is a snowy weather, it is necessary to have a special person to guard the door firmly to prevent the door leaf from blowing back under the action of the wind and hurting people or things. At the same time, the door shaft on one side is loaded with the weight of the door leaf for a long time, resulting in serious wear and deformation of the door frame.
