Abstract

A controllable hook lock mechanism of a folding type escalator step is provided with a hook provided with a limiting groove, the hook is connected with a shifting block, the end part of the shifting block is provided with a roller, a pin shaft is fixed on the shifting block, the hook is movably connected with the pin shaft, a torsional spring is arranged on the pin shaft, one end of the torsional spring is fixed on the hook, the other end of the torsional spring is fixed on a pin shaft, one end of the torsional spring is fixed on a step counter axle, and the other end of the torsional spring is fixed on a lantern ring of the. The utility model discloses use when the installation with the couple loose joint on the counter wheel axle of step, be connected mutually supporting with other parts again and just can realize the step folding and the expansion at the operation in-process, provide necessary part for making the required foldable step of portable escalator.

Description

The controlled hook lock mechanism of folding automatic escalator step

Technical field

The utility model relates to escalator step, especially a kind of parts of folding automatic escalator step.

Background technology

The structure of existing escalator step is connected with other parts as load-carrying element with A-frame and forms the integral body of rigidity, this step is not suitable for makes portable escalator, because the use occasion of portable escalator can not be provided with the ladder hole, when step moves to the staircase nadir, can not fold up the thickness of step is reduced, thereby step tread height overhead is higher, is not easy to the upper and lower escalator of passenger.

Summary of the invention

Can fold and launch for escalator step is in operation, the utility model provides a kind of controlled hook lock mechanism of folding automatic escalator step, so that step can be realized collapsible expansion as required, the thickness of step can change in its operational process.

The controlled hook lock mechanism of the folding automatic escalator step that the utility model provides, has the hook that is provided with position-limited trough, hook is connected with the shifting block that roller is equipped with in the end, be fixed with bearing pin on the shifting block, hook and bearing pin loose joint, one end is housed on the bearing pin is fixed on that hook is gone up, the other end is fixed on the torsion spring on the bearing pin, also be fixed with an end that is installed in the torsion spring on the step accessory whorl axle on the hook, the other end of torsion spring is fixed on the collar of accessory whorl axle.

The beneficial effects of the utility model are: hook of the present utility model is actively socketed on the accessory whorl axle of escalator step, be connected with other parts again and cooperatively interact, just can realize the folding and expansion of step in operational process, provide necessary parts for making the required collapsible step of portable escalator.

Description of drawings

Fig. 1, Fig. 2 be the utility model and with the schematic perspective view of two kinds of different lines of vision of other associated components bonded assembly.

In Fig. 1, Fig. 2,1. swing arm, 2. slide-bar, 3. hook, 4. pin, 5. shifting block, 6. torsion spring, 7. bearing pin, 8. roller, 9. bearing pin, the 10. collar, 11. torsion springs, 12. accessory whorls, 13. locating dowel pins, 14. accessory whorl axles, 15. position-limited troughs.Wherein link up with 3, pin 4, shifting block 5, torsion spring 6, bearing pin 7, roller 8, bearing pin 9, the collar 10, torsion spring 11, locating dowel pin 13 be component part of the present utility model.

The specific embodiment

With reference to Fig. 1, Fig. 2, hook 3 of the present utility model and shifting block 5 usefulness bearing pins 7 couple together, shifting block 5 is fixed on the bearing pin 7 in that pin 4 is set on the shifting block 5, hook 3 and bearing pin 7 loose joints, one end is installed on the bearing pin 7 to be fixed on the other end on the hook 3 and to be fixed on torsion spring 6 on the bearing pin 7, roller 8 is equipped with in the end of shifting block 5, roller 8 usefulness bearing pins 9 are connected on the shifting block 5, on hook 3, also be fixed with an end that is installed in the torsion spring 11 on the step accessory whorl axle 14, the other end of torsion spring 11 is fixed on the collar 10 of accessory whorl axle 14, and the locating dowel pin 13 that is arranged in the swing arm 1 is inserted in the position-limited trough of linking up with on 3 15.To link up with 3 when the utility model uses installation and be actively socketed on the step accessory whorl axle 14, hook 3 can be rotated on step accessory whorl axle 14.

Claims

1, a kind of controlled hook lock mechanism of folding automatic escalator step, it is characterized in that this mechanism has the hook that is provided with position-limited trough, hook is connected with the shifting block that roller is equipped with in the end, be fixed with bearing pin on the shifting block, hook and bearing pin loose joint, one end is housed on the bearing pin is fixed on that hook is gone up, the other end is fixed on the torsion spring on the bearing pin, also be fixed with an end that is installed in the torsion spring on the step accessory whorl axle on the hook, the other end of torsion spring is fixed on the collar of accessory whorl axle.
