Problems solved by technology

There is a problem in the implementation of the above-mentioned steps: the cushion is fixed with the seat of the vehicle, that is, the cushion is fixed, and at the same time, in order to increase the comfort of the cushion, the outer surface of the existing cushion is basically passed through Made of leather, fluff, etc., that is, there is a certain roughness on the outer surface of the cushion
When the firefighters turn their bodies, there will be greater friction between the firefighters and the seat cushion, which greatly increases the time it takes for firefighters to get out of the car, thus affecting the fire fighting

Embodiment 1

[0027] Such as figure 1 As shown, the rotating seat cushion used by this fire truck is made up of counterweight plate 1, connecting plate 2, limit post 3, housing 4 and so on. Wherein, both the counterweight plate 1 and the connecting plate 2 are disc-shaped and coaxial. In actual use, the counterweight plate 1 is placed on the seat to position the entire swivel cushion, and at this time, the connecting plate 2 is located on the upper side of the counterweight plate 1 .

[0028] The center of the lower end surface of the connecting plate 2 has a cylindrically protruding rotating shaft 2 a, and the rotating shaft 2 a is axially fixed with the counterweight plate 1 . Specifically, a slot is provided on the upper end surface of the weight plate 1 , and a bearing 5 is arranged in the slot, and the outer ring of the bearing 5 and the weight plate 1 are fixed together by welding. The rotating shaft 2a is in interference fit with the inner ring of the bearing 5, so as to achieve th...

Embodiment 2

[0036] The structure and principle of the second embodiment are basically the same as those of the first embodiment, except that the friction mechanism is a friction disc sleeved on the rotating shaft 2a, one end of the friction disc is fixedly connected with the weight plate 1, And the other end of the friction disc is against the connecting plate 2 .

Abstract

The invention provides a rotating cushion for a fire truck, belongs to the technical field of machinery, and solves the problem that a conventional cushion can disturb a fireman to get off the fire truck. The rotating cushion for the fire truck comprises a weight plate and a connecting plate located on the upper side of the weight plate, wherein the connecting plate and the weight plate are in the shape of a circular plate and are coaxial; a protruding rotating shaft is arranged at the central position of the lower end surface of the connecting plate, and the rotating shaft and the weight plate are axially fixed; a friction mechanism for generating frictional resistance between the weight plate and the connecting plate is arranged between the weight plate and the connecting plate; a housing with a closed chamber is fixedly connected to the upper end surface of the connecting plate, and is manufactured from flexible materials; the chamber is stuffed with sponge; the housing adopts the shape of the circular plate in a stuffed state; a limiting column is fixedly connected to the lower end surface of the connecting plate; and two limiting pieces which can separately prop against the limiting column are separately arranged on the weight plate when the connecting plate rotates relative to the weight plate, and the two limiting pieces are separately located on two sides of the limiting column. The rotating cushion for the fire truck disclosed by the invention has the advantage of shortening the time for getting off.

Description

technical field [0001] The invention belongs to the technical field of machinery, and relates to a rotating seat cushion, in particular to a rotating seat cushion for a fire truck. Background technique [0002] The cushion used on the existing fire engine is identical to that used on the common car, and they are all fixed by the seat of the vehicle through the connecting strip. When the seat cushion is used on a fire truck, because there is a large distance between the cab of the fire truck and the ground, when the firefighter comes out of the cab, two steps are generally required: 1. Turn the body first to align the body with the exit of the cab. Right on; 2. Firefighters come out of the cab through the exit. There is a problem in the implementation of the above-mentioned steps: the cushion is fixed with the seat of the vehicle, that is, the cushion is fixed, and at the same time, in order to increase the comfort of the cushion, the outer surface of the existing cushion is...
