Description

Connection set and LED box structure

Technical field

The utility model relates to a kind of connection set, especially a kind of connection set and LED box structure.

Background technique

LED display is formed by multiple casing is assembled, and it, as a kind of large display screen, is more and more applied.But in the occasion that some are of little use, such as concert, need often dismounting LED display or be assembled into difform LED display as required, for this reason, designer devises a kind of connection set of casing is assembled or dismounting fast.

Model utility content

The purpose of this utility model solves the deficiencies in the prior art, provides a kind of connection set and application thereof.

A kind of technological scheme of the present utility model:

A kind of connection set comprises the first link, controlling rod and the second link being axially arranged with through hole; Second link comprises pedestal and is located at the boss of pedestal upper surface, and the both sides of edges of pedestal lower surface is provided with the buckle along the second link axial direction, boss be circumferentially provided with gradually away from the chute of pedestal and chute be communicated with through hole; One end of first link is inserted in through hole in pedestal lower surface, and controlling rod inserts chute and is fixedly connected with the first link and slides up and down along through hole for controlling the first link, and the both sides of edges of the first link the other end is radially extended with intermediate plate; Also comprise the bounding means that restriction first link rotates freely in through hole.

Scheme is known thus, when two objects to be fixed are between the first link and the second link, controlling rod controls the first link along through hole upward sliding, after sliding into certain position, two objects to be fixed are sandwiched between the first link and the second link, bounding means limits the first link and rotates freely in through hole, and now, what two objects to be fixed were fixing is sandwiched between the first link and the second link; When unclamping two objects, pivoting lever in opposite direction, controlling rod controls the first link along through hole slide downward, and now, two objects are in releasing orientation.

Preferred version is that the middle part of the first link is provided with a screens portion, and bounding means is wire spring, and wire spring is located at the lower surface of pedestal and is rotated freely for limiting screens portion.

A kind of preferred version is that through hole is provided with internal thread away from pedestal side, and the first link inserts through-hole side and is provided with the outside thread with screw-internal thread fit.

Scheme is known thus, and the first link and the second link are threaded connection, and when object to be fixed is sandwiched in the first link and the second link, prevents loosening of object to be fixed better.

Another technological scheme of the utility model is:

A kind of LED box structure, comprises square casing, and the LED being located at tank surface shows module and connection set, and the frame of adjacent two tanks is sandwiched between the first link of connection set and the second link.

Comprehensive technique scheme is known, and the utility model has following beneficial effect: structure is simple, can firmly fix two objects to be fixed fast.

Above-mentioned explanation is only the general introduction of technical solutions of the utility model, in order to technological means of the present utility model can be better understood, and can be implemented according to the content of specification, and can become apparent to allow above and other object of the present utility model, feature and advantage, below especially exemplified by preferred embodiment, and coordinate accompanying drawing, be described in detail as follows.

Embodiment

It should be noted that, when not conflicting, the embodiment in the application and the feature in embodiment can combine mutually.Below in conjunction with accompanying drawing, the utility model is described further.

First embodiment, as shown in Figure 1 to Figure 3, a kind of connection set, comprising: the first link 1, controlling rod 3 and the second link 2 being axially arranged with through hole 25; Second link 2 comprises pedestal 22 and is located at the boss 21 of pedestal 22 upper surface, the both sides of edges of pedestal 22 lower surface is provided with the buckle 24 along the second link 2 axial direction, boss 21 be circumferentially provided with gradually away from the chute 23 of pedestal 22 and chute 23 be communicated with through hole 25; One end of first link 1 is inserted in through hole 25 in pedestal 22 upper surface, controlling rod 3 inserts chute 23 and is fixedly connected with the first link 1 and slides up and down along through hole 25 for controlling the first link 1, and the both sides of edges of first link 1 the other end is radially extended with intermediate plate 11; Also comprise the bounding means that restriction first link 1 rotates freely in through hole.

In the present embodiment, as depicted in figs. 1 and 2, the quantity of buckle 24 is 2.When two objects to be fixed are between the first link 1 and the second link 2, controlling rod 3 controls the first link 1 along through hole 25 upward sliding, after sliding into certain position, two objects to be fixed are sandwiched between the first link 1 and the second link 3, bounding means limits the first link 1 and rotates freely in through hole 25, now, what two objects to be fixed were fixing is sandwiched between the first link 1 and the second link 2; When unclamping two objects, pivoting lever 3 in opposite direction, controlling rod 3 controls the first link along through hole 25 slide downward, and now, two objects are in releasing orientation.

As shown in Figure 1, the middle part of the first link 1 is provided with screens portion 12, and bounding means is wire spring 26, and wire spring 26 is located at the lower surface of pedestal 22 and is rotated freely for limiting screens portion 12.When the first link 1 rotates to several angle, screens portion 12 clamps by wire spring 26, prevents from rotating freely in screens portion 12.

Second embodiment, the present embodiment and the first embodiment unlike: through hole 25 is provided with internal thread away from pedestal 22 side, and the first link 1 inserts through hole 25 side and is provided with the outside thread with screw-internal thread fit.First link 1 inserts after in through hole 25, and under the effect of external force, the first link 1 rotates along through hole about 25, prevents loosening of object to be fixed better.

3rd embodiment, as shown in Figures 4 to 6, a kind of LED box structure, comprises square casing 4, and the LED being located at casing 4 surface shows module and connection set, and the frame of adjacent two tanks is sandwiched between the first link 1 of connection set and the second link 2.

As Fig. 1, shown in Fig. 5 and Fig. 6, pivoting lever 3, makes controlling rod 3 be positioned at the bottommost of chute 23, now, the spacing of the first link 1 and the second link 2 is in maximum rating, is stuck between two buckles 24 by the frame of adjacent two tanks 4, then pivoting lever 3, controlling rod 3 is made to be positioned at the top of chute 23, now adjacent two tanks 4 is sandwiched between pedestal 22 and intermediate plate 11, and meanwhile, bounding means prevents that the first link 1 is relative with the second link 2 to be rotated; When adjacent two tanks 4 dismantled by needs, pivoting lever 3 in opposite direction, takes out connection set between adjacent two tanks 4 afterwards.

It is more than embodiment of the present utility model; it should be pointed out that for those skilled in the art, under the prerequisite not departing from the utility model principle; can also make some improvements and modifications, these improvements and modifications are also considered as protection domain of the present utility model.
