Abstract

The invention discloses a removable cover plate locking device for an escalator or a moving sidewalk. A key matched with a key hole is inserted in the key hole and then is rotated (namely a core bar is rotated) to drive a spray nozzle to rotate, so that the spray nozzle is inserted in a lock hole of a frame to lock the removable cover plate on the frame; and while the key is rotated in the opposite direction, the core bar is rotated to drive the spray nozzle to be released from the lock hole to unlock the removable cover plate (namely the removable cover plate is opened from the frame). Through the removable cover plate locking device, the movable cover plate is locked and unlocked with the frame, and the removable plate is unlocked only by the key, so that the removable cover plate is prevented from being stolen after being opened by non-professionals, which ensures the use safety of the escalator or the moving sidewalk.

The specific embodiment

Structure of the present invention is further set forth below in conjunction with accompanying drawing in .

are on escalator or moving sidewalk; Removable cover 1 covers on frame, and promptly removable cover 1 supports through frame, and frame generally comprises the side frame (not shown) that supports removable cover 1 left and right sides, the end frame 3 that supports removable cover 1 outer end; In Fig. 1-3; Blocking device avoids removable cover 1 arbitrarily to be opened or steal through locking removable cover 1 and end frame 3, certainly, and in other embodiment; Blocking device also can lock removable cover and side frame, and its principle is identical.

are in Fig. 1-3; Removable cover blocking device on escalator or the moving sidewalk; Comprise frame 3, be arranged on removable cover 1 on the frame 3, be opened in the mounting hole 11 of removable cover 1 upper surface, fixedly be inserted in lock core 4 in the mounting hole 11, be opened in the lockhole 12 on the frame 3, the lock mouth 9 that can insert lockhole 12 or be separated with lockhole 12, removable cover 1 is for having the section bar of die cavity 2, and mounting hole 11 is connected with die cavity 2; Lock core 4 passes mounting hole 11 and inserts in the die cavity 2; Be that lock core 4 is inserted in mounting hole 11 and the die cavity 2 simultaneously, the outer surface that lock core 4 is arranged in die cavity 2 is provided with outside thread, is combined with nut 7 on this outside thread; This nut 7 is pressed on the top inside face of removable cover 1 through pad 8; Extend to form protruding stop part 14 on the outer face of lock core 4 laterally, this stop part 14 is pressed on the top outside face of removable cover 1, and is as shown in Figure 3; Promptly be clamped in limit, the hole portion of mounting hole 11 on the removable cover 1, realize the fixed installation of lock core 4 on removable cover 1 through nut 7 and stop part 14.Lock core 4 has at the center and can offer on one end face of core bar 5 and be exposed to outer key hole 6 around the core bar 5 of its line of centers rotation, and an other end is provided with lock mouth 9; After the key that matches with key hole 6 like this was inserted in the key hole 6, the turn key promptly rotated core bar 5; Be with nozzle 9 to rotate, realizing that nozzle 9 inserts in the lockhole 11 of frame 3, realizes the locking of removable cover 1 on frame 3; Reversing sense turn key; Core bar 5 rotating bands nozzle 9 and are broken away from lockhole 11, and then the release removable cover 1, can open removable cover 1 from frame 3.Mention above, frame 3 is the end frame, and lock core 4 is in the middle part, outer end of removable cover 1, shown in Fig. 1-3, offers perforation 13 on the outer face of removable cover 1, and locking mouth 9 like this can pass 13 from boring a hole, thereby inserts lockhole 12.Through this removable cover blocking device; Realized removable cover 1 the locking and unlocking with frame 3; The release of removable cover 1 has only with key and could operate; Avoided removable cover to be opened like this, stoped removable cover to be stolen, guaranteed the safety that escalator or moving sidewalk use by the layman.

are in Fig. 3; The last outside face of removable cover 1 has the convex surface and the concave surface of permutation with repetition successively; The outer face of lock core 4 is pressed on through stop part 14 on the concave surface of outside face on the removable cover 1, the convex surface of the outside face setting that flushes on the outer face of lock core 4 and the removable cover 1.Though being set like this, lock core 4 still can guarantee the smooth of removable cover 1 surface.

are in Fig. 3; The fixed sturcture of lock mouth 9 on core bar 5 ends is following, and the end of core bar 5 is provided with outside thread, and this outside thread matches with a pair of nut 10; Offer perforation on the lock mouth 9; Core bar 5 passes the perforation of lock mouth 9, and this lock mouth 9 is clamped between a pair of nut 10, thereby realization core bar 5 is being with lock mouth 9 to rotate together.

to sum up; That this removable cover blocking device is installed is simple, easy to maintenance, good looking appearance, applicability are strong; The removable cover of escalator or moving sidewalk must just can be opened through the key of appointment; Play theft-proof effect, avoided removable cover arbitrarily to be opened the safety misadventure that causes.
