Embodiment
The LED of the utility model embodiment shows the module rapid dismounting apparatus, and its structure is as depicted in figs. 1 and 2, comprising: lock core 11 and the lock dog 12 that under the driving of said lock core 11, can stretch out or withdraw, lock dog 13.Lock dog 12 is symmetrical set with lock dog 13 relative lock cores 11.
The structure of said lock core 11 is as shown in Figure 4, is the gear of band rotating shaft, comprising: rotating shaft 112 and gear 113, and the two ends of rotating shaft 112 are provided with lockhole portion 111.Said lockhole portion 111 in this embodiment for being arranged on the inner hexagonal hole on the said rotating shaft 112 two ends end faces; When LED demonstration module is perhaps dismantled in the later stage assembling; Can adopt hex wrench to insert in the said inner hexagonal hole; Can twist lock core 11, finally drive lock dog 13 and stretch out and pin or withdraw and throw off.Certainly; Lockhole portion 111 also can be other boring ratio such as common interior delthyrium, interior four jiaos of holes or the like; Even can also not be the hole but the axle; Such as triangular prism oblique crank Z, quadrangular oblique crank Z, hexagon axle etc., drive lock core 11 as long as can be connected with supporting with it instrument easily and rotate, but the inner hexagonal hole effect that facts have proved the employing of this embodiment is better.
The structure of said lock dog 12 and lock dog 13 is actually the same, so this paper only introduces one of them.The concrete structure of said lock dog 13 is as shown in Figure 3, comprises latch part 130 and drive division 131.As shown in Figure 5, an end of said latch part 130 need stretch out and LED is shown that module 2 pins (such as being locked on the led display unit casing), so latch part 130 is generouser.And as shown in Figure 3, in order in economical with materials, further to improve the intensity of latch part 130, latch part 130 is provided with crisscross reinforcement 1301.Said drive division 131 has the tooth bar 132 suitable with said gear 113.Assembling backgear 113 and tooth bar 132 engagements in said lockhole portion 111, can drive lock core 11 rotations through instrumental purpose, finally drive lock dog 13 simultaneously and stretch out with lock dog 12 or withdraw.
The LED of the utility model embodiment shows that module 2 is as shown in Figure 5, and it has the LED demonstration module rapid dismounting apparatus 1 that two covers are symmetrical set.Certainly, also can be more than a cover or three covers reach as required.Every cover LED shows that module rapid dismounting apparatus 1 is mounted on the module drain pan 20 through a cover plate 21 and two groups of guide and limit structures 22.
Particularly, cover plate 21 is placed on LED and shows module rapid dismounting apparatus 1 middle part, and is provided with through hole and supplies the rotating shaft 112 of lock core 11 to pass through.Module drain pan 20 is provided with a plurality of screw columns 202, and cover plate 21 detachably is fixedly connected with module drain pan 20 through said screw column 202.Lock core 11 is through said rotating shaft 112 rotating being arranged between module drain pan 20 and the cover plate 21.
Said guide and limit structure 22 comprises guide housing 212.The latch part 130 of the said lock dog 13 in assembling back (or lock dog 12) promptly is arranged in said guide housing 212, and can be in the driving lower edge of lock core 11 guide housing 212 linear reciprocating motion within the specific limits, thereby stretch out or the guide housing of withdrawing.After reaching to a certain degree, can LED be shown the locking of module and led display unit casing, be withdrawn into to a certain degree after, can make LED show module and the disengaging of led display unit casing.
In the optimized technical scheme,, respectively be provided with a ring stiffener 211 at its two ends in order to strengthen the intensity of guide housing 212.
Further in the optimized technical scheme; Also remove a part of material at the middle part of guide housing 212; Thereby form and the spacing cantilever 213 of guide housing 212 integrated elasticity, and the end of the spacing cantilever 213 of elasticity has spacing block set (spacing block set is not shown in the drawings).Simultaneously as shown in Figure 3, put in place and break away from two extreme positions that put in place in the correspondence locking of lock dog 13 (or lock dog 12) latch part 130, offered the spacing breach 1302 in two places.Stretch out when putting in place in latch part 130, the spacing block set of the end of the spacing cantilever 213 of elasticity snaps in the spacing breach 1302; In like manner, when latch part 130 withdrawals put in place, the spacing cantilever 213 terminal spacing block sets of elasticity snapped in another spacing breach 1302.This kind structure is not only at dress, feel is better when tearing LED open and showing module; The operator can be felt when should stop the application of force; And the crucial mechanical stability of LED demonstration module rapid dismounting apparatus when being to improve locking state and disengaged position, prevent that it lost efficacy when receiving the slight disturbance of external force.
At last, needing ben is that rotating shaft 112 is step axles; Assembling back one of which end runs through cover plate 21, and the other end then runs through module drain pan 20, and all has lockhole portion 111 on its two ends end face; Thereby not only can dismantle LED demonstration module from behind, can also dismantle LED from the front and show module.
Above content is the further explain that combines concrete preferred implementation that the utility model is done, and can not assert that the practical implementation of the utility model is confined to these explanations.For the those of ordinary skill of technical field under the utility model, under the prerequisite that does not break away from the utility model design, can also make some simple deduction or replace, all should be regarded as belonging to the protection domain of the utility model.
