Abstract
The invention discloses a kind of front edge board triangulation chain anti-theft device, it is arranged on front plate for escalators by middle position, described front edge board is placed in staircase peripheral frame, described anti-theft device includes triangulation chain device and pull bar head, described triangulation chain device end is flexibly connected by bolt with pull bar head front end, this front edge board triangulation chain anti-theft device, connected by triangulation chain and pull rod device, composition interlinked mechanism, pull bar limits the free degree of pull bar through limiting plate, and be allowed to can only be elastic, then turn triangulation chain by triangular key and interlock pull bar elastic realization pinning front edge board, therefore, not only achieve front edge board self-locking anti-theft function but also do not affect integrally-built installation, and cost of manufacture is low, install and easy to operate.
Description
Technical field
The present invention relates to a kind of anti-theft device, the front plate for escalators anti-theft device of a kind of band triangulation chain.
Background technology
The front edge board of escalator is arranged on staircase and imports and exports position; play protection internal unit and the effect of carrying passenger; but owing to general front edge board does not arrange antitheft self-locking device; therefore anyone can open front edge board, thus causes potential safety hazard and staircase internal unit parts to have stolen risk.
Summary of the invention
The technical problem to be solved in the present invention is to provide a kind of simple in construction, easy to operate and can realize the anti-theft device of front edge board self-locking.
For solving the problems referred to above, the present invention is achieved by the following technical solutions:
A kind of front edge board triangulation chain anti-theft device, it is arranged on front plate for escalators by middle position, described front edge board is placed in staircase peripheral frame, and described anti-theft device includes that triangulation chain device and pull bar head, described triangulation chain device end are flexibly connected by bolt with pull bar head front end.
As preferably, described triangulation chain device includes that triangle lock body and swivel plate, described swivel plate are positioned at triangle lock body bottom and are connected with triangle lock bolt body fixing, and described swivel plate the other end has a waist typed through hole.
As preferably, described pull bar head includes lower shoe, upper motion bar and limiting plate, described limiting plate near staircase peripheral frame edge and vertical with front edge board be connected fixing, described lower shoe is fixing with upper motion bar end to be connected, described lower shoe is movably connected on waist typed through hole by bolt with the swivel plate end of triangulation chain, the described upper motion bar other end passes limiting plate, when upper motion bar moves upward to extreme position, described upper motion bar end stretches on the downside of staircase peripheral frame and overlaps with the lower frame of staircase peripheral frame, when upper motion bar is moved downwardly to extreme position, do not overlap on the downside of described upper motion bar end removal staircase peripheral frame and with the lower frame of staircase peripheral frame.
Compared with prior art, the invention have benefit that: this front edge board triangulation chain anti-theft device, connected by triangulation chain and pull rod device, composition interlinked mechanism, pull bar limits the free degree of pull bar through limiting plate, and be allowed to can only be elastic, then turns triangulation chain by triangular key and interlocks that pull bar is elastic realizes pinning front edge board, therefore, not only achieve front edge board self-locking anti-theft function but also do not affect integrally-built installation, and cost of manufacture is low, install and easy to operate.
Accompanying drawing illustrates:
The present invention is further described below in conjunction with the accompanying drawings:

Detailed description of the invention:
Below in conjunction with the accompanying drawings and detailed description of the invention describes the present invention:
nullOne front edge board triangulation chain anti-theft device of the present invention，Such as Fig. 1、Shown in Fig. 2，Overall structure is arranged on front plate for escalators 1 by middle position，Described front edge board 1 is arranged in staircase peripheral frame 2，Described anti-theft device includes triangulation chain device and pull bar head，Described triangulation chain device end is flexibly connected by bolt with pull bar head front end，Described triangulation chain device includes triangle lock body 3 and swivel plate 4，Described triangle lock body 3 upper bolt is fixedly connected on front edge board 1，Described swivel plate 4 is positioned at triangle lock body 3 bottom and is connected with triangle lock body 3 bolt fixing，Described pull bar head includes lower shoe 6、Upper motion bar 7 and limiting plate 8，Described limiting plate 8 is fixed near staircase peripheral frame 2 edge and be connected vertical with front edge board 1，Described lower shoe 6 is fixing with upper motion bar 7 end to be connected，Additionally also have a waist typed through hole 5 in described swivel plate 4 the other end，Described swivel plate 4 is movably connected on waist typed through hole 5 by bolt with lower shoe 6 end，Described upper motion bar 7 other end passes limiting plate 8，In actual application，When rotating counterclockwise under triangle lock body 3 is at artificial action，Described swivel plate 4 then rotates the most counterclockwise，Thus drive the lower shoe 6 of its end to move together with upper motion bar 7，It is positioned on limiting plate 8 due to the body of rod of upper motion bar 7 and lower shoe 6 end is movably connected on waist typed through hole 5，The most described lower shoe end moves upward on waist typed through hole，Described upper motion bar 7 can only move upward on limiting plate 8，When triangle lock body 3 rotates to extreme position，Described upper motion bar 7 also moves to extreme position and stopping moves upward and its end moves to the downside of staircase peripheral frame 2 and overlaps with the lower frame of staircase peripheral frame 2，Now if it is intended to open front edge board 1，Existence due to pull rod device，Motion bar 7 end is caused to be stuck on the downside of staircase peripheral frame 2，Prevent the unlatching of front edge board 1，It is achieved thereby that the self-locking action of front edge board 1，Otherwise，When turning clockwise under triangle lock body 3 is at artificial action，Due to triangulation chain device and the annexation of pull bar head，The unlocking action that can realize front edge board 1 opens front edge board then，Therefore，This front edge board triangulation chain anti-theft device not only achieves front edge board self-locking anti-theft function but also does not affect integrally-built installation，And cost of manufacture is low，Install and easy to operate，Can be used more widely.
It is emphasized that: be the most only presently preferred embodiments of the present invention, not the present invention is made any pro forma restriction, every any simple modification, equivalent variations and modification made above example according to the technical spirit of the present invention, all still falls within the range of technical solution of the present invention.
