As the technical scheme that the technical matters that the utility model proposed is adopted be: telescopic LED display casing davit includes: connecting link and holder; The top of described connecting link is provided with the locking bolt hole, the bottom is provided with stoping block, described holder is provided with the connecting rod through hole of being used to wear its end face and bottom surface, described connecting link is inserted in the connecting rod through hole on the holder, and it is characterized in that: the side of described holder is provided with the latch through hole of being used to wear the connecting rod through hole; Be provided with the resilient pin parts in the described latch through hole, on the bar wall of described connecting link, be provided with a pilot hole that cooperates with the resilient pin parts at least.
Described connecting link below be provided with one when connecting link becomes maximum contraction state downwards with respect to holder retaining bottom connecting link, prevent the connecting rod baffle plate that it comes off.
At least be provided with a contraction pilot hole that when connecting link becomes maximum contraction state downwards with respect to holder, cooperates the location on the sidewall of described connecting link, and one when upwards rising state with respect to holder one-tenth maximum, connecting link cooperates the rising pilot hole of locating with the resilient pin parts with the resilient pin parts.
Described resilient pin parts include: bolt rod, and the back-moving spring that bolt rod is advanced in the latch through hole, and the aperture that is provided with the latch through hole is encapsulated in latch mounting in the latch through hole with back-moving spring.
The top of described bolt rod is provided with the lateral pin that is used to stop back-moving spring, and back-moving spring is placed on the bolt rod, and the tail end of bolt rod extends outside the latch mounting, and crooked in the handle shape.
Be provided with in the described latch through hole for lateral pin and enter its interior lateral pin groove.
Of the present utility model produce effect for: can guarantee that the client is when the whole LED display that assembles of maintenance, do not tear open under the situation of other casings and can keep in repair or change any one casing separately, and can be with connecting link indentation display screen box body inside under the situation that does not need connecting link.Connecting link is subjected to can keep stable status under the effect of resilient pin parts, even when connecting link is collided in assembling process, connecting link can not shrink yet, and does not influence normal installation.
