Utility model content
The purpose of this utility model is in view of the shortcomings of the prior art, there is provided one kind has anti-climbing ability and user
Just attached wall ladder, prevents unexpected climbing.
The technical solution of the utility model is：A kind of attached wall ladder, including ladder body, the lower end of the ladder body are set
Anti-creep door is equipped with, the width of the anti-creep door is not less than the width of ladder body；The side of the anti-creep door is hinged by hinge
In on the side lever of ladder body, the side of the opposite side of anti-creep door offers keying hole, and being provided with locking on the inside of the keying hole fills
Put, the anti-creep door back side position corresponding with locking device offers groove, and the ladder body is provided with position with leading to
The corresponding hole clipping of groove, the anti-creep door can be locked at ladder body surface by the mating reaction of locking device and hole clipping.
Using such structure design, anti-creep door can by all coverings of the front of ladder body, and locking device with
Under the mating reaction of hole clipping on ladder, ladder body surface is locked at, to prevent the unexpected of the unrelated persons such as child from climbing, is prevented
Only contingency occurs.
Further, the locking device includes curb girder, crossbeam and crook, and the curb girder is perpendicularly fixed at anti-creep door
On front and rear inner surface, one end vertical articulation of the crossbeam is fixedly connected with keying on curb girder on the other end of the crossbeam
Post, the keying post are stretched out outdoors through hole is opened and closed to anti-creep, and slot is offered on the outer face for opening and closing post；It is described hook-shaped
The one end in portion is perpendicularly fixed on crossbeam.
Further, the crook includes lock pillar, and one end of the lock pillar is connected with crossbeam, solid on the other end of lock pillar
Surely there is fixture block, the angle of the fixture block medial surface and lock pillar is not less than 90 °, ensures locking effect.
Using such structure, curb girder is fixed on anti-creep door inner surface, and curb girder is played a supporting role to crossbeam, and horizontal
Beam uses movable connection with curb girder, and crossbeam is located in the plane parallel with anti-creep door；In addition, open and close the protruding keying of post
Hole, open and close hole and also function to supporting role to opening and closing post, under the support of both, crossbeam can be rotated stably, correspondingly, hook
Shape portion stably can also rotate with crossbeam.In use, the handle or key of form fit therewith, rotational handle are inserted in slot
Or key, crossbeam rotate with post is opened and closed, crook rotates with crossbeam, and when rotating clockwise, crook is also clockwise
Rotate, crook is through groove and close to hole clipping, and subsequent crook is fastened in hole clipping, and anti-creep door is realized with ladder body to be locked
Close；When needing to open anti-creep door, handle or key are rotated counterclockwise, crook rotates to opposite direction, leaves hole clipping, now can be with
Anti-creep door is outwardly opened.
Locking device structure of the present utility model is simple, reasonable, and cost is cheap, and the cost of manufacture of attached wall ladder is influenceed not
Greatly.
Further, one kind being shaped as in rectangle, square, cross of the slot cross section is preferably long
Square or cross, convenient use personnel substitute corresponding handle or key to open anti-creep with a word bottle opener or cross driver
Door, and general child can't usually carry with these instruments, so can equally play a part of preventing child from climbing.
Further, the diameter of the outer end for opening and closing post is more than the diameter for opening and closing hole, improves the fixed stably of locking device
It is qualitative.
Further, the length of the anti-creep door is 1.4 ~ 2m, preferably 1.4 ~ 1.55m.
Further, the locking device is arranged on the top half of anti-creep door, and preferable installation site is anti-creep door
Upper 1/4 part, prevents unrelated person picking lock.
Attached wall ladder structure of the present utility model is reasonable, easy to use, while preventing the unrelated persons such as child from climbing,
Being provided convenience for workmen, user of service can open anti-creep door with carry-on instrument, without being equipped with special key, system
It is low to make cost.
