Abstract
The beneficial effects of a locking device for LED box body connection in the utility model are that: the face-to-face edges of one LED box body are provided with an LED box body locking groove and a fixation portion respectively; when an edge lock hooks a fixation pin in a fixation portion of another LED box body to be connected, an inner angle wrench is utilized to rotate an inner angle screw of an edge lock in a screw hole of a cover plate; since the inner angle screw and the edge lock are not in the same circle center, when the inner angle screw is rotated, naturally, the edge lock stretches forward and backward, and the fixation pin can be loosened or locked; a locking arc bar on the round edge bottom of a locking portion in the edge lock is matched with an arc groove in a rotation gear, so that when the inner angle wrench rotates the inner angle screw, a positioning pin with toothed bars is in telescoping movement through the rotation gear, the positioning pin can enter or leave a positioning pin hole in the fixation portion; and when positioning pin enters the positioning pin hole, the two LED box body cannot be in dislocation movement.
Description
Technical field
The utility model relates to a kind of connection locking device, the mechanical structure technical field that particularly LED casing connects.
Background technology
Development along with LED display, for large LED display, by a plurality of little LED displays, formed, the weight ratio of LED display casing is larger, and along with overall panel is increasing, the weight of LED casing is also increasing, and stable connection between LED casing just directly affects display quality effect and the fail safe of LED display, during due to installation LED casing, work high above the ground mostly, and the locking method of traditional LED casing, but waste time and energy, can not meet current work and pursue high efficiency requirement, convenient for the connection between LED casing, save time, laborsaving and guaranteed just to have become safely LED large display screen installation instantly pursuit.
Utility model content
In view of background, the purpose of this utility model is install for LED casing convenient, save time, laborsaving and safety provides a kind of LED casing to connect locking device.
LED casing connects a locking device, comprising:
LED casing locked groove, described LED casing locked groove is arranged at the edge of LED casing;
Fixed part, comprises fixing pin and dowel hole, and described fixed part is arranged at the opposite side of LED box lock groove edge, and described fixing pin is vertical with fixed part plane, and described dowel hole is on LED casing edge side; And
Be positioned at square shape on the annular cushion block, annular cushion block of LED box lock trench bottom as the transmitting gear of " T " shape, be positioned at transmitting gear top the lock of the limit with interior angle screw, be placed in the other dowel with tooth bar of transmitting gear side;
Cover plate, has a screw hole and is placed on LED casing locked groove on described cover plate.
Preferably, described limit lock shape is as " 9 " word, and limit lock head is provided with movable circular tight lock part.
Preferably, the interior angle screw that described tight lock part is set and limit lock head be concentric protrude from limit lock head not, and described interior angle screw size is coincide with the screw hole of cover plate, and the round edge bottom of tight lock part is provided with locking arc bar.
Preferably, described transmitting gear top is circular, is provided with arc-shaped trench in annulus, and described arc-shaped trench coincide with locking arc bar.
The beneficial effects of the utility model are, in the edge of a LED casing, wherein on one side be provided with LED casing locked groove and another side is made as fixed part, after fixing pin in another LED casing fixed part that latch hook residence, limit will connect, with exterior angle spanner, the interior angle screw of the tight lock part in cover plate screw hole is rotated, because interior angle screw and limit lock head be not or not the same center of circle, during rotation, nature is done elastic by limit lock, with this, reach and unclamp or the tip that is locked, on the locking arc bar of the tight lock part round edge bottom of Bian Suozhong and transmitting gear, arc-shaped trench coincide, when exterior angle spanner rotates interior angle screw, by transmitting gear, the dowel with tooth bar is made to stretching motion, with this, reach the dowel hole that enters or leave fixed part, when entering dowel hole, be, the movement that can not misplace of two LED casings, thus, compared with prior art, the utility model is simple in structure, manufacture installation convenient, save time, laborsaving, two pretty good displacements of casing that can guarantee again locking are moving to reach firm safety.
Accompanying drawing explanation
Fig. 1 is the structure chart in the LED casing of place of the present utility model.
Fig. 2 is the enlarged drawing of A part in Fig. 1, is the enlarged drawing of the utility model structure chart.
In conjunction with structure chart of the present utility model, be described in detail.
Embodiment
In Fig. 1, the utility model comprises: LED casing locked groove 1, fixed part 2, comprise fixing pin 201 and dowel hole, be positioned at the annular cushion block 3 of LED casing locked groove 1, dowel 4 with tooth bar, shape is as the transmitting gear 5 of " T " shape, limit lock 6, cover plate 7, described annular cushion block 3 is positioned at the bottom of LED casing locked groove 1, the bottom of " T " of described transmitting gear 5 is arranged in annular cushion block 3, limit lock 6 is above transmitting gear 5, in the lock 6 of limit, the locking arc bar of the round edge bottom of tight lock part 601 and the arc-shaped trench on transmitting gear 5 501 coincide, cover plate 7 covers on limit lock 6, in the screw hole 701 of the interior angle screw 611 of tight lock part 601 in cover plate 7, described dowel 4 is in transmitting gear 5 one sides, the tooth bar of the tooth bar of transmitting gear 5 and dowel 4 coincide, when LED casing 10, after LED casing 20 is stitched together, the hook 602 of limit lock 6 is hooked in the fixing pin 201 in fixed part 2, by outer spanner, the interior angle screw 611 in the screw hole 701 of cover plate 7 is rotated counterclockwise, due to interior angle screw 611 and the not same center of circle of limit lock head, when interior angle screw 611 rotates, naturally make hook 602 have Telescopic, now, the hook 602 of limit lock 6 tip 201 that is strained and fixed, simultaneously, transmitting gear 5 rotates, dowel 4 is protruding enters the dowel hole in the fixed part 2 of the LED casing 20 that will connect, thus, two LED casings are stitched together and connect locking.To the utility model, provide described LED casing lifting locking device to be described in detail above, for one of ordinary skill in the art, thought according to the utility model embodiment, all will change in specific embodiments and applications, in sum, this description should not be construed as restriction of the present utility model.
