Abstract

The utility model discloses a high-speed train windscreen which comprises a frame, wherein, the frame is fixedly connected with a capsule which is formed by one-step compression molding through five-groove rotation and smooth transition, the other end of the capsule is fixedly connected with a compartment opening, a buffer assembly is installed between the upper part of the frame and the upper part of the compartment opening and along the direction of a central axis, the buffer assembly comprises a movable seat connected with the frame, a fixed seat connected with the compartment wall of the upper part of the compartment opening and a pressure spring between the two seats, the outer upper sides of both sides of the compartment opening and the outer lower sides of both sides of the frame are respectively connected through a draw rod with an extension spring, and one side of the outer end part of the frame is provided with a hooking fastener and a positioning pin. The utility model can better adapt to the railway environment of China and has the advantages of favorable rain-proof, sound-insulating, heat-insulating and heat-preserving properties, high strength, large extension, adaptation to a wide range of environmental temperature and long service life.

Description

Fast train windscreen

(1) technical field:

The utility model relates to the attaching parts between a kind of railway rapid compartment, relates in particular to a kind of Fast train windscreen.

(2) background technology:

Windscreen is the attaching parts between the passenger train railway car, its effect is the inner passage that forms anti-rainwater, sound insulation, heat insulation, security seal, the windscreen that generally uses has following several at present: one, homemade iron winds retaining and drum type brake are assembled windscreen, both ends of the surface do not have and connect hanging fastener, can not reach seal request thereby easily produce the slit when train is crossed bend, turnout.Iron winds retaining particularly, windproof, anti-rainwater, sound insulation, heat insulation, heat-insulating property is very poor, is unfavorable for the air-conditioning insulation compartment in, when train was crossed bend, turnout, the friction of iron winds retaining both ends of the surface was sent ear-piercing cry, the formation noise.Even more serious is to squeeze the hand and the pin of hindering the passenger easily, causes safety hazard.Two, import Tent folding windshield, though in profile, hang up all and improve to some extent, vestibule diaphragm thickness has only 2mm, is again that film is made and formed, sound insulation, heat insulation, rainproof water-based can be difficult to long-term the assurance.China railways is influenced by geographical conditions, and the detour turnout is many, and turning radius is little, the vestibule diaphragm of making, and extending range is little, and the huge pulling force when being difficult to resist the train turning is easy to cause canopy Bu Latuo, breakage.Aluminium chassis top does not have control, ceaselessly rocks back and forth, and causes the windscreen instability, is to quicken the key factor that canopy cloth damages yet, and therefore improving windscreen is the task of top priority.

(3) summary of the invention:

Technical problem to be solved in the utility model just provides and a kind ofly can adapt to the China railways environment better, have good anti-rainwater, sound insulation, heat insulation, heat-insulating property, and high strength, the big stretching, extension, the range of temperatures that conforms is wide, the Fast train windscreen of long service life.

In order to solve the problems of the technologies described above, the technical solution that Fast train windscreen of the present utility model adopted is such: it comprises framework, described framework is captiveed joint with capsule, this capsule is the once molding formed capsule of the revolution of five grooves, rounding off, and the other end of capsule is captiveed joint with the compartment mouth; Along the axis direction buffering assembly is installed between framework upper and the mouth top, compartment, this buffering assembly comprises the pressure spring between the railway carriage or compartment wall bonded assembly permanent seat on and framework bonded assembly sliding seat, and mouth top, compartment and two; Outside the mouth both sides, compartment outside upside and the framework both sides between the downside respectively the pull bar by a band extension spring be connected; Framework outer end one side is provided with hook fastener and locating dowel pin.

Described capsule is made with multilaminar high strength degree cord fabric and specific rubber mold pressing.

After adopting technique scheme, because Fast train windscreen of the present utility model adopts the once molding formed capsule of the revolution of five grooves, rounding off, captive joint with the compartment mouth with framework respectively in the two ends of capsule, form the inner passage, overcome canopy cloth make many because of joint, pin hole causes leaking gas more, seepy question; Mold pressing capsule non junction, maximum elongation and minimal compression that can realization itself, and elongation is the twice of import vestibule diaphragm, because of its sound insulation of compression molding, heat insulation, heat-insulating property all considerably beyond Tent folding windshield.Capsule is made with multilaminar high strength degree cord fabric and specific rubber mold pressing, and thickness is the twice of canopy cloth, thus the intensity height, long service life, good water-proof effect is easy to install, dismounting.Again owing to along the axis direction buffering assembly is installed between framework upper and the mouth top, compartment, this buffering assembly comprises the pressure spring between the railway carriage or compartment wall bonded assembly permanent seat on and framework bonded assembly sliding seat, and mouth top, compartment and two, application force by pressure spring is controlled at the spindle axis center with framework, big waving can not occur; Pressure spring is installed on the axis of windscreen, still be that capsule can not damaged in the turnout so cross bend, and the stability of windscreen has also improved greatly.The utility model good looking appearance is beautiful, and the range of temperatures that conforms is-50 ℃～+ 50 ℃, can adapt to the China railways environment better.

Fig. 1 is the scheme drawing of the utility model Fast train windscreen;

Fig. 2 is the front elevation of capsule in the windscreen shown in Figure 1;

Fig. 3 is the lateral plan of capsule in the windscreen shown in Figure 1.

(5) specific embodiment:

In conjunction with Fig. 1, Fig. 2, Fig. 3 as seen, Fast train windscreen of the present utility model comprises aluminum alloy frame 1, and framework 1 is captiveed joint with capsule 2, and this capsule 2 is five grooves, 3 revolving structures, 3 of each grooves are rounding off, capsule 2 usefulness multilaminar high strength degree cord fabric and specific rubber is once molding formed makes.The other end of capsule 2 is captiveed joint with compartment mouth 4, forms the inner passage.Along the axis direction buffering assembly is installed between framework 1 top and compartment mouth 4 tops; this buffering assembly comprises the spiral pressure spring 7 between the railway carriage or compartment wall bonded assembly permanent seat 6 on one and framework 1 bonded assembly sliding seat 5, and compartment mouth 4 tops and two 5,6; spring 7 usefulness nuts are separately fixed on sliding seat 5 and the permanent seat 6; its effect is that wave on control framework 1 top; increase the stability that windscreen is in operation; also be convenient to connect and hang, and protect capsule 2 to avoid damaging effectively.Outside compartment mouth 4 both sides outside upside and framework 1 both sides between the downside respectively the pull bar 8 by a band extension spring be connected, the effect of pull bar 8 is fixed frame 1 and capsule 2 on the whole.Windscreen internal channel bottom is equipped with pedal 9, and framework 1 outer end one side is provided with corrosion-resistant steel hook fastener 10 and locating dowel pin 11.Two windscreens connect extension and just can form a complete seal channel.

Certainly, the shock absorbers such as pressure spring that other also can be set between framework upper and the mouth top, compartment substitute spiral pressure spring; Connection mode between spiral pressure spring two ends and framework upper and the mouth top, compartment is not limit.Above-mentioned variation is all to realize the purpose of this utility model degree of being.
