Description
Technical field
The utility model relates to apparatus for automatically lifting, refers in particular to a kind of elevator lock of the escalator for the automatic upper and lower stair of people.
Background technology
Nowadays, in each emporium in city, conveniently customer buys article, has all installed escalator between each floor.Rising below step at escalator, install and manyly safeguard the equipment that elevator normally runs, so that the producer of escalator carries out normal maintenance process simulation to this product, and this plays the fastened screw fastening of step on the fuselage of escalator.Due to machine work of not stopping work night and day, trip bolt easily loosens; Fastening screw nail leads directly to the equipment safeguarding that elevator normally runs, the dust accumulated over a long period, the water stain normal operation jeopardizing these equipment; Trip bolt is easily turned on, and is easy to the undue loss causing personal injury and machine.These, bring many inconvenience all to the producer of escalator.
Summary of the invention
The purpose of this utility model is to overcome above-mentioned the deficiencies in the prior art part, and provides a kind of elevator to lock.
The utility model is achieved by the following technical solution: the utility model forms primarily of tapered end, locking bar, base and key, described tapered end comprises dust cap and pad composition, dust cap is a closed tubular, its closed one end is a boss, the shaping well-regulated projection in its outer face or groove, chute is had in the circumferentially symmetry of the cylindrical shell of dust cap, pad is connected in the inner face that one end closed by dust cap, the centre bore of pad is the geometric form of rule, and in the surrounding of centre bore, uniform some holes, described locking bar is by screw rod, locking plate, spacer, greatly, little spring and ball composition, spacer center in disc-shaped is through hole, symmetrical blind hole is provided with in one end, and groove is provided with in the circumferential wall of longitudinal direction, ball one end compresses little spring in blind hole, the other end is pressed in the corresponding aperture of the surrounding of pad centre bore, one end and the centre bore of pad are that the screw rod that the geometry of rule is identical passes big spring, spacer centre bore, insert the pad centre bore of same shape with it, its other end is then through the aperture of base, and by securing member, the locking plate perpendicular to screw axis is connected, big spring one end is resisted against on the shaft shoulder of screw rod, the other end is resisted against the side of spacer, described base is tubular, its one end is provided with end cap, identical with the cylindrical shell external diameter circumferentially having chute of the cylindrical shell of dust cap away from the internal diameter of the macropore of end cap one end, the aperture of end cap one end wears for screw rod, base pin symmetry is fixedly arranged in the pin hole of base, and when the macropore of base is inserted in dust cap cylindrical shell, after being inserted through the chute circumferentially of the cylindrical shell of dust cap, the groove Inner that the circumferential wall embedding spacer longitudinal direction is provided with, described key one end is handle, and another termination and tapered end close the shaping well-regulated projection in outer face of one end or groove is that male and female matches.
At the contact surface of dust cap and base, be lined with wear-resistant seal circle.
The utility model is owing to being closed the starting pedal surface of escalator completely by dust cap, dust, the falling into of rain stain are stopped completely, also the problems such as the easy loose Off of trip bolt are fundamentally solved, only have the key of special coupling just can carry out unlatching operation, further increase application life and the safety factor of machine.

Accompanying drawing is the utility model structural representation.
Detailed description of the invention:
See accompanying drawing, the utility model forms primarily of tapered end 1, locking bar 2, base 3 and key 4, described tapered end 1 comprises dust cap 11 and pad 12 forms, dust cap 11 is a closed tubular, its closed one end is a boss, the shaping well-regulated projection in its outer face or groove, chute 111 is had in the circumferentially symmetry of the cylindrical shell of dust cap 11, pad 12 is connected in the inner face that one end closed by dust cap 11, the centre bore 121 of pad 12 is the geometric form of rule, and in the surrounding of centre bore, uniform some holes 122, described locking bar 2 is by screw rod 21, locking plate 22, spacer 23, greatly, little spring 24, 25 and ball 26 form, spacer 23 center in disc-shaped is through hole 231, symmetrical blind hole 232 is provided with in one end, and groove 233 is provided with in the circumferential wall of longitudinal direction, ball 26 one end compresses little spring 25 in blind hole 232, the other end is pressed in the corresponding aperture 122 of the surrounding of pad 12 centre bore 121, one end and the centre bore 121 of pad 12 are that the screw rod 21 that the geometry of rule is identical passes big spring 24, spacer 23 centre bore 231, insert pad 12 centre bore 121 of same shape with it, its other end is then through the aperture of base 3, and by securing member, the locking plate 22 perpendicular to screw rod 21 axis is connected, big spring 24 one end is resisted against on the shaft shoulder of screw rod 21, the other end is resisted against the side of spacer 23, described base 3 is in tubular, its one end is provided with end cap, identical with the cylindrical shell external diameter circumferentially having chute 111 of the cylindrical shell of dust cap 11 away from the internal diameter of the macropore 31 of end cap one end, the aperture 32 of end cap one end wears for screw rod 21, base pin 33 symmetry is fixedly arranged in the pin hole 34 of base, and when the macropore 31 of base 3 is inserted in dust cap 11 cylindrical shell, after being inserted through the chute circumferentially of the cylindrical shell of dust cap 11, groove 233 Inner that the circumferential wall embedding spacer 23 longitudinal direction is provided with, described key 4 one end is handle, and the shaping well-regulated projection in outer face of one end closed by another termination and dust cap 11 or groove is that male and female matches.
At the contact surface of dust cap 11 with base, be lined with wear-resistant seal circle.
When using the utility model, key 4 being inserted dust cap 11 closes in the shaping groove in the outer face of one end, because both are that male and female matches, turn shank, because base 3 has one end of end cap to be fixed on it elevator machine, and base pin 33 symmetry is fixedly arranged in the pin hole 34 of base, when the macropore 31 of base 3 is inserted in dust cap 11 cylindrical shell, after base pin 33 is inserted through the chute 111 circumferentially of the cylindrical shell of dust cap 11, groove 233 Inner that the circumferential wall embedding spacer 23 longitudinal direction is provided with, dust cap 11 rotates, that is be connected in pad 12 synchronous rotary that the inner face of one end closed by dust cap 11, with identical screw rod 21 synchronous axial system of geometry that the centre bore 121 of pad 12 is rule, and the locking plate 22 perpendicular to screw rod 21 axis is rotated by securing member by drive, open, block action, because base pin 33 limits the rotation of spacer 23, and pad 12 and the contact surface of spacer 23 be only one end compress little spring 25 in blind hole 232, the other end is pressed on ball 26 in the corresponding aperture 122 of the surrounding of pad 12 centre bore 121, when both produce relative motion, 26, ball skids off original position, until fall into the corresponding aperture 122 of the surrounding of next pad 12 centre bore 121, so far, the action of an open and close lock completes.
