The specific embodiment
Below in conjunction with accompanying drawing, the specific embodiment of the present utility model is elaborated.
Refer to the machine room interlock step device shown in Fig. 1 to Fig. 4, comprise that it comprises support 1, the first rotating shaft 2, the second rotating shaft 3, connecting rod 4, axle sleeve 5, pedal 6 and lock pin 7.
Support 1 vertically arranges, and its upper end is fixedly mounted on the entrance of leading to escalator or moving sidewalk machine room.For easy to make, support 1 adopts the support of both sides bending.
The quantity of pedal 6 is a plurality of, and the present embodiment is preferably two.Two pedals 6 are along the short transverse inner side that is arranged on support 1 spaced apart of support 1, and one end of each pedal 6 is rotatably connected on support 1 by the first rotating shaft 2.The first rotating shaft 2 is extended setting along the width of support 1, and its two ends activity runs through the both sides of support 1 and by a lock pin 7, is fixed on support 1 respectively, and each pedal 6 is provided with the oval hole of passing for the first rotating shaft 2 activities.The other end of each pedal 6 can be from turning to a fixed angle with support 1 state that fits along the first rotating shaft 2, and the fixed angle described in the present embodiment is 90 °.In the present embodiment, the first rotating shaft is for having strong market potential.
Each pedal 6 is provided with in the same side along the width of support 1 and extends the second rotating shaft 3 arranging.Described machine room interlock step device also comprises the connecting rod 4 that extends setting along the short transverse of support 1, and the second rotating shaft 3 on each pedal 6 is rotatably connected on connecting rod 4.On connecting rod 4, corresponding each second rotating shaft 3 is installed with axle sleeve 5, and axle sleeve 5 is set in the second rotating shaft 3 rotatably.The second rotating shaft 3 is fixed by a lock pin 7 after running through rotationally connecting rod 4.In the present embodiment, the second rotating shaft 3 is short pin, and its one end is welded on the side of pedal 6.
By the drive of connecting rod 4, support 1, two pedals 6 and connecting rod 4 form parallelogram folding structures.While pulling connecting rod 4, can drive two pedals 6 to launch simultaneously or be folded to and the support state that fits.
Refer to Fig. 3, the second rotating shaft 3 on the side of support 1 on corresponding each pedal 6 offers L shaped draw-in groove 8, L-type draw-in groove 8 has the notch 81 of offering towards the open side of support 1, and is connected with notch 81 and the chute 82 along the short transverse of support 1 to downward-extension.
Under not use state, together with two pedals 6 all fit with support 1, shown in laminating protruding Fig. 1 of shape and Fig. 2.Now connecting rod 4 is positioned at the outside of support 1, and the lateral projection of connecting rod 4 overlaps on the lateral surface of support 1.The second rotating shaft 3 is positioned at the bottom of chute 82.Refer to Fig. 3, in use, connecting rod 4 is upwards carried, the second rotating shaft 3 moves up to the position of notch 81 along chute 82, the first rotating shaft 2 is positioned at the least significant end in the oval hole of pedal 6 relatively, then connecting rod 4 is pulled outwardly, and pedal 6 is turned to support 1 and be a step of 90 ° of formation.The end of pedal 6 is also provided with a chamfering, when rotating, the end of pedal 6 is fitted better with the inner side of support 1, more firm.
Mathematical Modeling in the present embodiment as shown in Figure 4, the state that support 1 and pedal fit, the first rotating shaft 2 be b with respect to the bottom distance of pedal 6, as the pedal 6 oval hole circle heart O that the first rotating shaft 2 is passed through on pedal 6 during in non-working condition
1be rotating hole 61, make pedal 6 abut in the inner side of support 1, because the radius of gyration b of pedal 6 is now greater than the space length a that 2, pedal can pass through, so pedal 6 can not overturn, also just can not damage operating personnel.When using this equipment, upwards lift pull bar 4, make the oval hole on pedal 6 slip over the first rotating shaft 2, thereby make oval hole circle heart O
2it is the position that rotating hole 62 arrives the first rotating shaft 2, now the radius of gyration a of pedal 6 equals the space length a that 6, pedal can pass through just, pedal 6 can be reversed, when pedal 6 is turned to 90 °, the bottom surface of pedal 6 just and stand 1 fit together, now upset finishes, and pedal 6 is in level, easy to use.Use while finishing, only need pull-up connecting rod 4 by all 6 while of pedals reverse flip, and the second rotating shaft 3 is entered in the notch 81 of L-type draw-in groove 8, all pedals 6 all turn to and stand fit-state, then put down connecting rod 4, the second rotating shaft 3 slides down to chute 82 bottoms, now all pedals 6 all relative the first rotating shaft 2 along self oval hole down sliding, reset.
As can be seen here, machine room interlock device with pedal of the present utility model, by connecting rod 4, link, can launch a plurality of pedals 6 simultaneously or a plurality of pedals 6 are packed up simultaneously to the support device that fits, and by the effect that snaps in of the L-type draw-in groove 8 on support 1 and the second rotating shaft 3, can avoid the non-artificial effect of connecting rod 4 and be lifted.When pedal is launched, only have first connecting rod 4 is upwards carried, then to support 1 outside pull-up, just can make the second rotating shaft 3 exit L-type draw-in groove 8, thereby a plurality of pedals 6 could be launched.Therefore, the utility model is easy to operate, uses safer.
Above-described embodiment is only explanation technical conceive of the present utility model and feature; its object is to allow person skilled in the art can understand content of the present utility model and implement according to this; can not limit protection domain of the present utility model with this; all equivalences of doing according to the utility model Spirit Essence change or modify, within all should being encompassed in protection domain of the present utility model.
