The car of elevator
Technical field
The utility model relates to a kind of car of elevator.
Background technology
In the prior art, the car of elevator comprises car cab, and car cab integral body is square column type.This car cab moves up and down under the drive of the trailer coupling of elevator, and the top of car cab is subjected to the resistance of air very big in motion process, and can produce strong noise during the elevator operation, easily influence is equipped with the interior environment of building of elevator, easily causes use cost to increase again.
Summary of the invention
The utility model purpose provides a kind of car of elevator, and its resistance suffered when upward movement is less, the sound of generation a little less than.
For achieving the above object, the technical solution adopted in the utility model is: a kind of car of elevator, comprise car cab, and the top of described car cab has car roof, and described car roof is truncated cone-shaped.
Because technique scheme utilization, the utility model compared with prior art has following advantage: because car roof is truncated cone-shaped, so when the car cab upward movement, it is less that it is the truncated cone-shaped suffered air resistance of car roof, a little less than making sound that car cab when motion produce, thereby the noise pollution that makes elevator operate in to cause in the building is less, is convenient to elevator and extends in the buildings such as office building and use.
Description of drawings
Accompanying drawing 1 is installed on front view on the car frame for the utility model;
Accompanying drawing 2 is installed on right elevation on the car frame for the utility model;
Accompanying drawing 3 is a birds-eye view of the present utility model;
Wherein: 1, car frame; 2, car cab; 3, trailer coupling; 4, car roof;
The specific embodiment
Referring to accompanying drawing 1-accompanying drawing 3, a kind of car of elevator comprises car cab 2, and the top of described car cab 2 has car roof 4, and described car roof 4 is truncated cone-shaped.In each embodiment shown in the drawings, the cross section of car cab 2 is square, so described car roof 4 is designed to be the taper of truncation side.
The utility model is installed on the car frame 1, the trailer coupling 3 of elevator also is installed on car frame 1, when elevator is opened operation, trailer coupling 3 traction car cabs 2 make it move up and down along car frame 1, when car cab 2 upward movements, because car roof 4 is the taper of truncation side, so the drag effect of car roof 4 suffered air is less, the noise that makes car cab 2 produce in motion process is also less, can avoid in the building of elevator is installed, causing noise emission, can save use cost again, be convenient to elevator is generalized to as using in the buildings such as office office building.
