Description

Syndeton between the casing that a kind of LED lifting curtain wall display screen is used

Technical field

The utility model relates to LED lifting curtain wall display screen technology field, is specifically related to the improvement aspect of link between the casing of LED lifting curtain wall display screen.

Background technology

Traditional LED lifting curtain wall display screen is formed by a plurality of independently box body combinations, establishes the davit of two fixed lobes on the end face of casing, and davit extend in the casing of top from the tank floor of top, connects by the bolt pieces locking.If the user is after assembling whole LED lifting curtain wall display screen, when needing maintenance or changing one of them casing, because two davits of box top inject in another casing of top, and cause and can't separately this casing be split out, all casings below this casing need be split out, the casing that could will need repairing or change splits out, reversed in order during installation, the casing that needs repairing or change is installed, all casings below this casing could be installed; Resources such as a large amount of time and manpower, inefficiency are wasted in operation like this.

Summary of the invention

In sum, the syndeton that the purpose of this utility model is to solve between two the neighbouring casings that have LED lifting curtain wall display screen now is not easy to independent dismounting, maintenance or replacing complicated operation, ineffective problem, and syndeton between the casing that a kind of LED lifting curtain wall display screen that proposes is used.

The technical scheme that adopts for the solution technical matters that the utility model proposed is: syndeton between the casing that a kind of LED lifting curtain wall display screen is used, comprise at least two casings, be connected by being located at link in the lower box and the bolt pieces in the upper box between two neighbouring casings, it is characterized in that: described link includes davit, holder and coupling shaft, and described davit front end is provided with the locking bolt through hole that is connected with bolt pieces; Described holder is provided with the davit swivelling chute, and the davit tail end is located in the davit swivelling chute, and davit flexibly connects by coupling shaft and holder; The end face of described holder is fixedlyed connected with lower box roof medial surface, respectively is provided with a davit turnover breach on lower box roof and upper box diapire.

As being to the further improved technical scheme of the utility model:

Described davit tail end side is provided with pilot hole, is provided with the bayonet lock through hole on the sidewall of described holder, is provided with the bayonet lock of the clamping location of matching with pilot hole in the bayonet lock through hole, and the tail end of bayonet lock also is provided with the bayonet lock spring.

A wherein end of the aperture of described bayonet lock through hole and coupling shaft is provided with a slice mounting, and mounting is fixed on the side of holder by the mounting screw.

It is the right angle gap slot that 90 degree rotations are carried out in the center of circle with the coupling shaft for davit only that described davit swivelling chute is one.

The beneficial effects of the utility model are: after LED lifting curtain wall display screen assembles, when needing one of them casing of dismounting, the locking bolt of this bottom half is opened, the davit of this casing lower square box is pulled in this casing, simultaneously the lock inspection of this casing top bottom half is opened, the davit that connects on this casing holder with the coupling shaft on this Connection Block be the center of circle revolve turn 90 degrees after, put up with separately this casing is pulled down, need not to move other casing, the operation steps of this casing of assembling is opposite separately, the utility model is convenient to operation, increases work efficiency.

Embodiment

Below in conjunction with accompanying drawing and preferred specific embodiment structure of the present utility model is further described:

Shown in Fig. 5, the utility model is formed by connecting by a plurality of box body combinations, two neighbouring casings, the two ends, the inside bottom wall face left and right sides of its upper box 1 respectively are provided with a bolt pieces 3, be fixedly connected with a link 4 on the roof medial surface of its lower box 2, link 4 is provided with a davit 41 that can spin upside down 90 degree, is respectively equipped with

davit turnover breach

11,21 on lower box 2 roofs and upper box 1 diapire.When assembling connected, davit 41 overturn from

davit turnover breach

11,21 and enters in the upper box 1, connects by bolt pieces 3 lockings; During dismounting, withdraw from bolt pieces 3, davit 41 turns over to turn 90 degrees and returns in the lower box 2, can dismantle one of them casing in the LED lifting curtain wall display screen separately, and is convenient to use.

Link 4 also includes holder 42, coupling shaft 43, bayonet lock 44, bayonet lock spring 45, mounting 46 and mounting fixed screw 47 except including a davit 41.Davit 41 front ends are provided with the locking bolt through hole that is connected with bolt pieces, and the tail end side is provided with an axle connecting hole 412, are provided with hemispheric location blind hole 413 at the hole of axle connecting hole 412 periphery.The end face of holder 42 is to be fixedly connected on casing roof medial surface, end face and trailing flank at holder 42 are provided with a right angle gap slot 421, the left side wall of right angle gap slot 421 is provided with shaft through-hole 4211, right side wall is provided with corresponding axle blind hole 4212, is provided with bayonet lock through hole 4213 on the right side wall of right angle gap slot 421.Davit 41 tail ends are located in the right angle gap slot 421, after the shaft through-hole 4211 of coupling shaft 43 from the left side wall of right angle gap slot 421 inserts, in the axle connecting hole 412 of davit 41 tail ends is inserted in axle blind hole 4212 on right angle gap slot 421 right side walls.Davit 41 is subjected to the restriction of coupling shaft 43 and right angle gap slot 421, can only be that the center of circle becomes 90 degree rotations with connecting shaft 43, also is davit 41 90 degree of can turning over when upright state, becomes horizontality.Bayonet lock 44 is a cone-shaped body, be located in the bayonet lock through hole 4213 location of matching with the hemispheric location blind hole 413 of davit 41 tail ends, when davit 41 is upright state, bayonet lock 44 tops peak at hemispheric location blind hole 413, tail end at bayonet lock 44 also is provided with the bayonet lock spring 45 that is used for bayonet lock 44 is applied elastic force, the right-hand member of the aperture of bayonet lock through hole 4213 and coupling shaft 43 is provided with a slice mounting 46, mounting 46 is fixed on the right flank of holder 42 by mounting screw 47, prevents from that bayonet lock spring 45 and coupling shaft 43 from withdrawing to come off.
