Abstract

The invention provides a pedal lock for an escalator or an automatic pedestrian path. The pedal lock comprises a lock case, a lock cylinder, a spring, a lock rod, a locking plate and an end cover, wherein an outer ring stage of the lock cylinder and an inner ring stage of the lock case are stopped in a way of being matched with each other; the lock rod passes through a hole of the end cover, the spring and a central hole of the lock cylinder; a stop stage on the lock rod is matched with the lower end face of the lock cylinder; the end faces of the lock rod, the lock cylinder and the lock case are flush with one another; the lower end of the lock rod is provided with the locking plate; and the spring is arranged between the lock cylinder and the end cover. By adopting the structure, firstly, the lock cylinder and the lock case are in sliding fit with each other and the lock cylinder and the lock rod are in sliding fit with each other, a gap between the lock case and the lock cylinder and a gap between the lock case and the lock rod are small, so water and dust are prevented from entering the lock; and in the resetting process of the lock cylinder, dust or water between the lock cylinder and the lock case and between the lock cylinder and a carrier rod is ejected, so unavailable unlocking of a key of the lock is effectively prevented; secondly, since the end faces of the lock rod, the lock cylinder and the lock case are flush with one another, incorrect operation due to treading can be effectively prevented; thirdly, the lock can be unlocked in a staircase only by rotating the carrier rod; and fourthly, the pedal lock has the advantages of simple structure, no precision component and convenient manufacturing and maintenance.

Description

The pedal lock of a kind of escalator or automatic pedestrian path

Technical field

A kind of novel staircase pedal anti-theft device is particularly locked at a kind of pedal of public traffic type staircase.

Background technology

Prior art generally adopts the mode of key switch or screw to prevent that escalator treadboards is stolen at present.These locking devices have following deficiency: 1, generally core is a strip, when being used for the public traffic type staircase, trampling for a long time and can bring a large amount of earth into lockhole, and causing maintenance is that key can't be opened.2. lockhole is a precision component, and it is stuck to be used for easily getting rusty when outdoor.3. adopt screw that pedal is fixed on form on the pedal frame, illegally reach real antitheft order ground.4. adopting bolt can't reach EN115-2008 requires: " the pedal lock can be opened internally ".

Summary of the invention

The objective of the invention is: the pedal lock of a kind of escalator or automatic pedestrian path is provided, and it is not only safeguarded simply, and waterproof, prevents trampling the sand prevention function.

The present invention is achieved in that the pedal lock of a kind of escalator or automatic pedestrian path, comprises lock housing, lock core, spring, locking bar, latch and end cap, and its special character is: the outer shroud platform of lock core cooperates stop bit with the interior ring platform of lock housing; Locking bar passes the centre bore of hole, spring and the lock core of end cap, and the stop bit platform on the locking bar cooperates with the lower surface of lock core; Locking bar, lock core are concordant with the lock housing end face, and the locking bar lower end is provided with latch; Spring is arranged between lock core and the end cap.

The pedal lock of described a kind of escalator or automatic pedestrian path, its special character is: the upper end of locking bar has along the axial key hole of locking bar.

The pedal lock of described a kind of escalator or automatic pedestrian path, its special character is: there is the hexagon blind hole upper end of the centre bore of described lock core, and the locking bar upper end is six prismatics.

The pedal lock of a kind of escalator of the present invention or automatic pedestrian path, owing to adopt such structure, the one, lock core and lock housing and lock core and locking bar are slidingly matched, gap between lock housing and lock core and the locking bar is little, can prevent that sealing, sand and dust enter, and in the process that lock core resets, the dust between lock core and lock housing and lock core and the push rod or moisture are ejected, can prevent effectively that key from can't unblank; The 2nd, locking bar, lock core are concordant with the lock housing end face, can prevent from effectively to trample, and cause maloperation.The 3rd, in staircase, also can unblank, only need to rotate push rod and get final product; The 4th, simple in structure, no precise part, manufacturing and easy to maintenance.

Description of drawings

Fig. 1 is a sectional view of the present invention.

Fig. 2 is the sectional view of user mode of the present invention.

The specific embodiment

Below in conjunction with accompanying drawing the present invention is further described.

As shown in Figure 1, the pedal of a kind of escalator or automatic pedestrian path lock comprises lock housing 1, lock core 2, spring 3, locking bar 4, latch 5 and end cap 6, and the outer shroud platform of lock core 2 cooperates stop bit with the interior ring platform of lock housing 1; Locking bar 4 passes the centre bore of hole, spring 3 and the lock core 2 of end cap 6, and the stop bit platform 41 on the locking bar 4 cooperates with the lower surface of lock core 2; Locking bar 4, lock core 2 are concordant with lock housing 1 three's end face, and locking bar 4 lower ends are provided with latch 5; Push rod and end cap articulate.Locking bar 4 articulates with end cap 6.

Spring 3 is arranged between lock core 2 and the end cap 6.

The upper end of locking bar 4 has along the axial key hole 42 of locking bar 4.

As another kind of embodiment: there is the hexagon blind hole upper end that also can be the centre bore of lock core 2, and locking bar 4 upper ends are six prismatics.

As shown in Figure 2, the present invention in use, lock housing is fixed on the pedal 7, the state among Fig. 2 is that pedal 7 is locked together in framework 8.

Key cooperates with key hole on the locking bar 4, and key promotes lock core 2 and moves down, and the top of locking bar 4 enters in the hole on the key, rotates key then, and locking bar 4 is rotated, and latch 5 rotates with locking bar 4.Latch 5 leaves framework 8.Extract key, then lock core 2 resets under spring 3 effects.

Above-described only is preferential embodiment of the present invention.Should be pointed out that for the person of ordinary skill of the art under the situation that does not break away from the principle of the invention, can also make some improvement and modification, this also is considered as protection scope of the present invention.
