Abstract
The utility model relates to an self-acting turnover treadle, particularly in an self-acting turnover treadle using for the bunk beds of the railway carriage, which one end of the base is provided with a shaft, one end of the pedal is actively connected with the shaft, and connected with a leaf spring arranged on the base, the front of the pedal is sealed with a cover plate, and a cavity is formed between the cover plate and the front of the pedal, a torsion spring which is used to control the angle position of the pedal is arranged in the cavity, a layer of padding plate is consolidated on the surface of the pedal rear part, a fluorescence plate is arranged on the pedal. The inner leaf spring achieves the angle limit of the pedal, the torsion spring achieves the dynamic function of self-acting turnover, to make the pedal achieve the effect of three different angle locations, different functions. The rubber padding plate improves comfort of the passengers, and reduces the weight of the shell shaped pedal, and the cavity formed by the shell shaped pedal and the cover can be used to fix the torsion spring. The utility model has the advantages of novel and practical structure, comfort, safety and reliability.
Description
Technical field:
The utility model relates to a kind of automatic folding steps, is used in particular for the automatic folding steps in passenger train two-berth that passenger train soft sleeper, the box-type sleeping berth of hard berth make things convenient for the passenger two-berth to use.
Background technology:
Existing train two-berth is ice-cold hard uncomfortable with its step tread plate of pedal, and the passenger uses inconvenience, is easy to the passenger that damages.Its structure is by the friction force of the nylon washer on the axle, manually realize two grades of folding positions of step tread plate.The passenger in lower berth steps on less than pedal when manually closing 0 ° of angle, for a long time when opening 90 ° of positions, the passenger that easily collides with again, when vehicle operating nylon washer loosening, when friction force reduces, easily vibrate and open the position from closing the position, easily produce noise.General effect no matter outward appearance, structure, traveling comfort is relatively poor.
Summary of the invention:
Goal of the invention of the present utility model be to overcome the deficiencies in the prior art, it is housing structure that a kind of stretcher is provided, and the curved surface slyness is comfortable, attractive in appearance, safe and reliable, practical, have fluorescent plate shows the automatic folding steps in passenger train two-berth bright, that make things convenient for the two-berth to use.
Realize the foregoing invention purpose by the following technical solutions: the automatic folding steps in a kind of passenger train two-berth, comprise installation stretcher base on the wall, its structural feature is: an end of described base is equipped with axle, stretcher one end flexibly connects with axle, touch with the leaf spring that is installed in base end, the front portion cover plate for sealing of this stretcher, the front portion of cover plate and stretcher forms cavity, the torsion spring of control pin pedal angle position is installed in this cavity, fixed one deck backing plate on the posterior face of described stretcher, stretcher and base are provided with fluorescent plate.
Owing to adopted technique scheme, compared with prior art, inner leaf spring of the utility model realizes that the angle of stretcher is spacing, and torsion spring realizes that upset automatically with moving function, achieves the effect of stretcher at three different angles positions, difference in functionality.Rubber pad has improved passenger's traveling comfort, has also reduced the weight of shelly stretcher, and shelly stretcher and cover plate form cavity and be used to install torsion spring, this structure utility model, comfortable, safe and reliable.
Description of drawings
Fig. 1 is a front view of the present utility model.
Fig. 2 is the lateral plan of Fig. 1.
Fig. 3 is a normality scheme drawing of the present utility model.
Fig. 4 is the scheme drawing of the utility model closed state.
The specific embodiment
Referring to accompanying drawing 1, Fig. 2, Fig. 3 and Fig. 4, the utility model is made up of stretcher 5, base 2, axle 6, packing ring 3, torsion spring 4, axle 6, cover plate 7 etc.One end installation shaft 6 of base 2, the front end of stretcher 5 flexibly connects with axle 6, cooperates with the leaf spring 8 that is installed in base 2 ends to touch.The front portion of stretcher 5 presss from both sides pad washer 3 with cover plate 7 sealings, cover plate 7 with the front portion of stretcher 5, and packing ring 3 is nylon washers.Cover plate 7 forms a narrow and small cavity with the front portion of stretcher 5, and the torsion spring 4 of control pin pedal 5 angle positions is installed in the cavity.Fixed one deck backing plate 9 on the posterior face of stretcher 5, backing plate 9 is rubber tie plates.Be provided with the fluorescent plate 1 that opens bright illumination for the two-berth on the bottom of stretcher 5 and the base 2.
Principle of work of the present utility model and process:
Stretcher 5 of the present utility model is formed one with base 2, axle 6, packing ring 3, torsion spring 4, cover plate 7, realizes that upset automatically is with moving function.Base 2 realizes that with leaf spring 8, stretcher 5 angle of stretcher is spacing, achieves the effect of stretcher 5 at three different angles positions, difference in functionality.The backing plate 9 that elastomeric material is made is bonded on the stretcher 5 of shelly, and this set can improve passenger's traveling comfort.As Fig. 3, when the common function position of stretcher 5 was located at 45 °, when foot-operated upward stretcher 5 was exerted oneself, stretcher 5 forwarded as shown in Figure 2 about 88 ° to, and this moment, sole was treaded stretcher 5.When pin leaves stretcher 5, be turned to back effect lower limit about 45 ° automatically at leaf spring 8 at stretcher 5 under the effect of torsion spring 4.As Fig. 4, when needs stretcher 5 closes or the passenger closes to 0 ° when running into stretcher 5 accidentally.Finger catches on stretcher 5 one and draws and get final product 45 ° to the common function position when needs stretcher 5 is opened.
