Abstract
The utility model provides an antitheft and anti-loosening device for a machine room cover plate, which comprises a front-edge plate connected with a machine room cover plate, a front-edge plate enclosure frame, a triangular lock, a triangular lock barrier strip, and a truss string beam. The front-edge plate arranged in the front-edge plate enclosure frame is provided with the triangular lock. The truss string beam is arranged below the triangular lock. The triangular lock barrier strip is arranged between the triangular lock and the truss string beam. A clip spring is provided to cling to the triangular lock barrier strip. The bottom of the clip spring is fixedly connected with the truss string beam. According to the utility model, the barrier strip is clamped by the clip spring, so that the stopping of a ladder due to the frequent vibration of the barrier strip is avoided.
Description
Technical field
The utility model relates to a kind of escalator machine room cover plate anti-theft anti-loosing device.
Background technology
Machine room cover plate anti-theft anti-loosing device generally is the triangulation chain blend stop to be set enclosing to be provided with between frame and the truss between the loosing-proof device; Because the vibrations of forward position plate in the staircase operational process; The staircase operation is of a specified duration, and bolt is loosening easily, can cause the blend stop displacement; Thereby cause non-artificial property to stop ladder, make troubles to the passenger
Summary of the invention
The utility model is the deficiency that overcomes prior art, and machine room cover plate anti-theft anti-loosing device is improved, and a kind of staircase long-time running machine room cover plate loosing-proof device is provided.
The utility model is realized through following technical scheme: machine room cover plate anti-theft anti-loosing device; Comprise that the forward position plate, the forward position plate that are connected on the machine room cover plate enclose frame, triangulation chain, triangulation chain blend stop and truss string beam; Said forward position plate encloses the forward position plate is set in the frame; Said forward position plate is provided with said triangulation chain, is truss string beam below the said triangulation chain, between said triangulation chain and said truss string beam, is provided with the triangulation chain blend stop; One jump ring is close to said triangulation chain blend stop, and said jump ring bottom is fixedly connected on the said truss string beam.
Adopt jump ring to block blend stop at present, avoid frequently stopping ladder because of shaking.
Description of drawings
Fig. 1 is the utility model machine room cover plate anti-theft anti-loosing apparatus structure scheme drawing;
Fig. 2 is that Figure 1B is to view;
Wherein: 1, forward position plate; 2, the forward position plate encloses frame; 3, triangulation chain; 4, triangulation chain blend stop; 5, truss string beam; 6, jump ring.
The specific embodiment
Below in conjunction with accompanying drawing the invention is explained further details.
As shown in Figure 1; Machine room cover plate anti-theft anti-loosing device; Comprise that the forward position plate 1, the forward position plate that are connected on the machine room cover plate enclose frame 2, triangulation chain 3, triangulation chain blend stop 4 and truss string beam 5, said forward position plate encloses forward position plate 1 is set in the frame 2, and said forward position plate 1 is provided with said triangulation chain 3; Below the said triangulation chain 3 is truss string beam 5; Between said triangulation chain 3 and said truss string beam 5, be provided with triangulation chain blend stop 4, it is characterized in that: a jump ring 6 is close to said triangulation chain blend stop 4, and said jump ring 6 bottoms are fixedly connected on the said truss string beam 5.
Adopt jump ring to block blend stop at present, avoid frequently stopping ladder because of shaking.
