Embodiment
In order to clearly, complete description the utility model, below in conjunction with the utility model accompanying drawing, the utility model is described in further detail.
As shown in Figure 2-5, the utility model proposes a kind of quick connection lock for LED display, comprise top lifting plate 1 and bottom fixed board 2, top lifting plate 1 is installed on the sidewall of a LED display casing, bottom fixed board 2 is installed on the sidewall of another LED display casing, it also comprises locking device, and locking device is for locking top lifting plate 1 and bottom fixed board 2, and locking device comprises middle davit 3, horizontal pin 4 and bottom locking and regulating device 5.Each accessory of the present utility model is separate, adopts special mould to carry out standardized design, subsequent production flow process is accelerated and cost of production reduction.
As shown in Figure 6, middle davit 3 comprises cylindrical bar 31 and cylindrical bar base 32, cylindrical bar 31 and cylindrical bar base 32 be coaxial arrange and cylindrical bar 31 perpendicular to cylindrical bar base 32, the diameter of cylindrical bar 31 is less than the diameter of cylindrical bar base 32, cylindrical bar 31 is diametrically provided with a semi-circular through hole 33 near its top end, cylindrical bar 31 is provided with cylindrical bump 34 near cylindrical bar base 32 place, cylindrical bump 34 is perpendicular to cylindrical bar 31, described cylindrical bar 31 is through bottom fixed board 32, and horizontal pin 4 is through described semi-circular through hole 33.
As Figure 7-8, bottom locking and regulating device 5 is socketed on described middle davit 3, locking and regulating device 5 inside, bottom is provided with the screw thread notch 51 mated with described cylindrical bump 34, and middle davit 3 can be moved up and down with coordinating of screw thread notch 51 by described cylindrical bump 34.
When carrying out the assembling of locking device, first the cylindrical bar 31 of middle davit 3 is passed from the bottom surface of bottom locking and regulating device 5, make the cylindrical bar base 32 of middle davit 3 concordant with the bottom surface of bottom locking and regulating device 5, again middle davit 3 is lifted plate 2 through bottom, finally horizontal pin 4 is inserted into the assembling that the semi-circular through hole 33 corresponding with it can complete locking device.Preferably, also comprise supported spring 6, described supported spring 6 is arranged between bottom fixed board 2 and bottom locking and regulating device 5.
As a kind of preferred version, as Figure 7-8, the side of bottom locking and regulating device 5 is provided with regulating handle 52, and regulating handle 52 is along the downward-sloping setting of axis of bottom locking and regulating device 5.Locking and regulating device 5 side, bottom is provided with regulating handle 52, and the downward-sloping setting of regulating handle 52, when making rotating base locking and regulating device 5, be more easy to have an effect, thus reduce the waste of manpower.The utility model by middle davit 3 and bottom locking and regulating device 5 redesign, the own dimensions that quick links is locked diminishes, thus quick connection lock reduces the requirement of housing interior volume when follow-up use, reduce box house by the part stopped, thus improve the reliability of casing follow-up maintenance greatly.
Casing carries the splicing that quick connection lock structure can more rapidly and efficiently realize between casing.When splicing, by locking device through after bottom lifting plate 2, again through top lifting plate 1, then, rotating base locking and regulating device 2 left, cylindrical bump 34 due to the stop of the screw thread draw-in groove 51 of bottom locking and regulating device 5 inside, thus can make middle davit 3 follow bottom locking and regulating device 5 horizontal pin 4 to be snapped in top lifting plate 1 to anticlockwise; After horizontal pin 4 snaps in top lifting plate 1, rotating base locking and regulating device 5 to the right again, by the routing motion of cylindrical bump 34 with screw thread draw-in groove 51, middle davit 3 can be moved down, now, because horizontal pin 4 has snapped in top lifting plate 1, middle davit 3 moves down and top lifting plate 1 will be driven to move down, thus it is close to bottom lifting plate 2 to realize top lifting plate 1, continue rotating base locking and regulating device 5 and can realize the locking that top lifting plate 1 and bottom lift plate 2, finally, the splicing between two tanks can just be completed.When dismantling, only need by bottom locking and regulating device 5 to anticlockwise, middle davit 3 moves up, then bottom locking and regulating device 5 is made horizontal pin 4 90-degree rotation to right rotation, and can complete dismounting, operation is simple and reliable.
Only as described above, be only the preferred embodiment of the utility model, certainly the scope of this novel enforcement can not be limited with this, namely generally make simple equivalence change according to the content described in the utility model claim and model utility specification and modify, all still belong within the utility model claim scope.In addition, summary part and title are only used to the use of auxiliary patent document search, are not used for the interest field of restriction the utility model.
