[0019] The utility model is further introduced below in conjunction with drawings Figures 1-2 And one specific embodiment of the utility model is described in detail, but it should be understood that the protection scope of the utility model is not limited by specific embodiment.

[0020] A kind of pull-out type pedal device that can realize limit fixing, including the ladder body component of pedal ladder, storage plate 7, limit plate 4 and locking device 5.

[0021] The ladder body assembly comprises a ladder 1, a round pipe 3, a guide plate 6 and a sliding plate 8. The ladder 1 is fixedly connected between the two guide plates 6, and the feet of the passengers can be stepped on when the ladder is used. The round pipe 3 is fixed at the ends of the two guide plates 6 and extends out of the guide plates 6. The two sliding plates 8 are fixedly arranged on the two sides of the guide plate 6, and the sliding plates 8 are made of polytetrafluoroethylene material, which is used for the stable sliding of the ladder body assembly in the pulled-out state, and saves the labor and prevents the outer side of the ladder body assembly from colliding with and scratching the vehicle body when the ladder is used.

[0022] As shown in the figure, the storage plate 7 is fixedly installed in the limited installation space of the special vehicle, and is used for storing the ladder body assembly in the non-use state of the ladder device. The guide groove 2 is arranged on the storage plate 7, and the two ends of the round pipe 3 extending out of the guide plate 6 are installed in the guide groove 2. The round pipe 3 slides along the length direction of the guide groove 2, thereby driving the whole ladder body assembly to slide along the length direction of the guide groove 2.

[0023] The two limiting plates 4 are arranged at the lower parts of the two sides of the guide groove 2. The limiting plates 4 are installed on the storage plate 7 by welding or screwing. The limiting plates 4 are in the shape of a long rectangular strip, and one end is provided with a bent structure. The angle of the bending is calculated according to the angle formed by the guide plate 6 and the storage plate 7 when the ladder body assembly is pulled out for use. The strength of the limiting plate 4 is calculated and determined according to the load requirement when the ladder body assembly is pulled out for use. When the ladder body assembly is stored in the storage plate 7 in the non-use state, the limiting plate 4 provides the support and storage functions. When the ladder body assembly is used, the ladder body assembly is pulled out to the outermost side of the guide groove 2. The round pipe 3 is used as the shaft, and is rotated to the position where the guide plate 6 contacts the bent part of the limiting plate 4. At this time, the limiting plate 4 provides the support and limiting functions.

[0024] The locking device 5 is a touch locking mechanism, which is fixedly installed on the bottom ladder. When the handle of the pulling mechanism is pulled, the protrusion on the ladder body assembly is stored in the assembly, the ladder body assembly is smoothly pulled out, the handle is released, the protrusion is returned to the original position, the locking mechanism is unlocked, and the device is in the working state. When the ladder assembly needs to be stored, the handle of the pulling mechanism is pulled, the protrusion is stored in the assembly, the ladder assembly is pushed to the innermost side of the guide groove, the handle is released, the protrusion is returned to the original position, the locking device 5 is locked, and the device is in the closed state.

[0025] In specific use, the locking device 5 is unlocked, the ladder body assembly is pulled out along the direction of the guide groove 2 to the outermost side of the guide groove 2, the round pipe 3 is used as the shaft, and is rotated to the position of the limiting plate 4, so as to realize the working state of the ladder. After use, the lowermost part of the ladder body assembly is supported, the round pipe 3 is used as the shaft, the ladder body assembly is rotated to the horizontal position first, and then the ladder body assembly is pushed into the guide groove 2 along the direction of the guide groove 2 until the innermost side of the guide groove 2, so as to complete the storage of the ladder body assembly. Finally, the locking mechanism is locked, and the closed state of the ladder is realized.

[0026] Combination Figure 1In the closed state of the pedaling device, the round pipe is located at the innermost side of the guide groove, and the pedaling device is locked by the locking device 5 of the ladder;

[0027] In combination Figure 2 In the working state of the pedaling device, when the pedaling device is needed to be used, the pedaling ladder is pulled out along the guide groove, the round pipe is located at the outermost side of the guide groove, and the pedaling ladder is rotated around the round pipe to be clamped by the limiting plate, so that the normal use of the pedaling device is realized.

[0028] Although the embodiments of the utility model have been shown and described, it can be understood by those skilled in the art that various changes, modifications, replacements and variations can be made to these embodiments without departing from the principles and spirits of the utility model, and the scope of the utility model is defined by the appended claims and their equivalents.
