Abstract

The utility model provides a wind adjusting device for the ventilation pipe of a passenger vehicle. The device comprises an arc-shaped wind-shielding plate, a screw cover, and a locating shaft piece. Two locating shaft sections are arranged on the two ends of the arc-shaped wind-shielding plate is connected in an adhesive manner on the inner side of a wind inlet, and matched in size with the wind inlet. The screw cover is provided with a poking block, which is embedded with the two sides of an arc-shaped slot opened on the ventilation pipe, and the two sides of an axial slot opened on the adjusting section of the ventilation pipe. Two locating sections are sleeved on the external circumference of the roller drum of the locating shaft piece and the inner circumference of the ventilation pipe. The bottom seat of the locating shaft piece is connected with the framework of the ventilation pipe. The device can facilitate the adjustment of the amount of wind from the ventilation pipe, and has the advantages of simple structure, low manufacture cost, convenient cleaning of the wind outlet and beautiful appearance of the vehicle.

Description

A kind of volume adjusting apparatus of ventilation of passenger train pipe

Technical field

The utility model relates to the drafting apparatus of passenger vehicle, specifically is meant a kind of volume adjusting apparatus of ventilation of passenger train pipe.

Background technology

The breather pipe of existing passenger vehicle adopts the air quantity of being located at the air outlet position to regulate cell sructure usually, air quantity is regulated by different passengers' needs, though this structure is easy to use, but also there are grid and adjustment means complexity thereof, the cost of manufacture height, fragile, simultaneously, dust is easily assembled at the grid position, and is not easy to clean, influenced the aesthetic in the compartment.

Summary of the invention

The purpose of this utility model is to overcome the shortcoming of above-mentioned prior art, proposes a kind of volume adjusting apparatus simple, low, easy to use, the attractive in appearance later-model ventilation of passenger train pipe of cost of making.

The purpose of this utility model realizes by following proposal: the volume adjusting apparatus of this ventilation of passenger train pipe, comprise the arc plate that keeps out the wind, rotation set, fix shaft spare, the described arc plate two ends of keeping out the wind are provided with the location shaft part, the middle part is provided with regulates section, amplexiform the inboard of the ventilation inlet position of described keep out the wind arc plate and breather pipe, and the arc plate that keeps out the wind is corresponding with the ventilation inlet size, described rotation set is provided with pulling block, described shifting block successively with breather pipe on the deep-slotted chip breaker both sides offered and regulate the axial groove both sides interlocking of offering on the section, two location shaft parts respectively with the inner peripheral surface socket of the beam barrel outer circumference surface and the breather pipe of fix shaft spare, the base of described fix shaft spare is captiveed joint with the framework of breather pipe.

For realizing the utility model better, when the described rotation set of rotation, make the deep-slotted chip breaker that the pulling block of rotation set offers and regulate in the axial groove of offering on the section and rotate on breather pipe, thereby driving the described arc plate that keeps out the wind rotates around fix shaft spare, the angular range of rotation is 0～45 °, so just, can control the position of the arc plate that keeps out the wind by rotation set, and then control breather pipe intake, realize the air quantity adjusting.

Integrated two wedges side by side that are located at the rotation set inner peripheral surface of described shifting block.

The beam barrel of described fix shaft spare is an end opening, the short tube that the other end seals.

The utility model has following advantage and effect with respect to prior art: by this volume adjusting apparatus, can conveniently regulate the breather pipe air output, it is simple in structure, and cost of manufacture is low, and air outlet is easy to clean, makes the compartment more attractive in appearance.
