Embodiment

Need to prove that under the situation of not conflicting, embodiment and the feature among the embodiment among the application can make up mutually.Describe the utility model below with reference to the accompanying drawings and in conjunction with the embodiments in detail.

Fig. 1 and Fig. 2 show the structural representation according to the embodiment one of the application's led display unit, and embodiment one led display unit comprises LED framework 10, LED display modular 60 and fixing bolt 20.LED framework 10 comprises the installation through hole that extends along first direction, the second surface that LED framework 10 has first surface and is oppositely arranged with first surface, install through hole comprise near the first hole section 11 of first surface and near the aperture of the second hole section, 12, the first hole sections 11 of second surface greater than the second hole section 12.LED display modular 60 is installed on the first surface, and LED display modular 60 has and lead to the hole site first through hole 61 corresponding and that extend along first direction is installed.Fixing bolt 20 comprises bolt shank 21 and bolt head 22, and bolt head 22 is arranged in the first hole section 11, and bolt shank 21 is located in the second hole section 12, and bolt head 22 has force section 221 away from an end of bolt shank 21.Wherein, the cross-section area of the cross-section area of first through hole 61 and the second hole section 12 is all less than the cross-section area of bolt head 22.

Bolt head 22 that is to say in the first hole section 11 that along first direction is spacing the aperture of the aperture of the second hole section 12 and first through hole 61 all is located in the second hole section 12 less than the maximum radial dimension bolt shank 21 of bolt head 22.From the above, bolt head 22 can not pass the second hole section 12 and break away from LED framework 10.Fig. 3 and Fig. 4 show the installation process of led display unit, utilize instrument to pass first through hole 61 and cooperate with the force section of bolt head 22, thereby screw bolt shank 21 it are penetrated in fixed support 30 fixtures such as grade.Because LED display modular 60 is installed on the LED framework 10, so LED display modular 60 is fixed on the fixture such as fixed support 30, and fixed support 30 has the tapped hole 31 that cooperates with bolt shank 21.From the above, staff's just installing in the face of led display unit at led display unit.Fig. 5 and Fig. 6 show the unloading process of led display unit, because the diameter of first through hole 61 is less than the maximum radial dimension of bolt head 22, bolt head 22 can not pass first through hole 61, utilizing instrument to pass first through hole 61 cooperates with the force section of bolt head 22, thereby screwing bolt shank 21 withdraws from it from fixed support 30 fixtures such as grade, bolt head 22 is replaced at the back side of LED display modular 60 and is driven LED display modular 60 away from fixtures such as fixed supports 30, thereby in the led display unit front led display unit is disassembled from fixed support 30 fixtures such as grade.

In the unloading process of led display unit, bolt head 22 can be replaced the back side at LED display modular 60.In order to prevent that bolt head 22 from damaging LED display modular 60, especially at thinner LED display modular 60, as shown in Figure 2, embodiment one led display unit also comprises stop member 40.Through hole is installed is also comprised the 3rd hole section 13, the first hole section 11 is between the second hole section 12 and the 3rd hole section 13, the cross-section area of the 3rd hole section 13 is greater than the cross-section area of the first hole section 11, stop member 40 be removably mounted in the 3rd hole section 13 and have along first direction extend and with the aperture of first through hole, 61 corresponding second through hole, 41, the second through holes 41 diameter less than bolt head 22.Earlier fixing bolt 20 is penetrated LED framework 10 from the first surface of LED framework 10, then stop member 40 is installed in the 3rd hole section 13, again LED display modular 60 is fixed on the first surface of LED framework 10.From the above, bolt head 22 is limited between stop member 40 and the second hole section 12, and when the dismounting led display unit, bolt head 22 is replaced on stop member 40, thereby can not contact with LED display modular 60, also just can not damage LED display modular 60.

As shown in Figure 2, the 3rd hole section 13 internal surfaces have first internal thread, and the outer surface of stop member 40 has first outside thread with first screw-internal thread fit.Like this, the installation and removal of stop member 40 have been made things convenient for.Certainly, stop member 40 also can be installed in the 3rd hole section 13 by other means.

When bolt head 22 is replaced on stop member 40, bolt head 22 produces frictional force with stop member 40 contacted two surfaces, thereby makes 22 pairs of stop members of bolt head 40 produce warping forces.Preferably, first of the stop member 40 externally threaded rotation direction is opposite with the second externally threaded rotation direction of bolt shank 21.Can prevent effectively that like this stop member 40 is rotated out from the 3rd hole section 13, replace at the back side of LED display modular 60, and then damage LED display modular 60.

In the present embodiment, the hole wall of second through hole 41 has first application of force tangent plane.Can stretch in second through hole 41 by the instrument that cooperates with second through hole 41, and screw stop member 40, stop member 40 is installed in the 3rd hole section 13.The end face of stop member 40 can arrange the groove of yi word pattern, with the instrument that is similar to the yi word pattern screw-driver stop member 40 is screwed in the 3rd hole section 13.

To shown in Figure 6, the force section 221 of bolt head 22 is groove as Fig. 3, and the cell wall of groove is provided with second application of force tangent plane.Can pass first through hole 61 and second through hole 41 by the instrument with groove fit, drive bolt head 22 and rotate.Groove is preferably hexagonal indentations, just can drive fixing bolt 20 by hex wrench 50 commonly used in the prior art and rotate.Certainly, second through hole 41 in the stop member 40 will leave the gap with hex wrench 50, so that stop member 40 can not interfered the rotation of hex wrench 50.The cross section of second through hole 41 can be Hexagon, penetrates in second through hole 41 by the hex wrench bigger than the size of hex wrench 50, and stop member 40 is screwed in the 3rd hole section 13.

Embodiment two according to the application's led display unit is not shown in figures, embodiment two is with embodiment one difference, install in the through hole the 3rd hole section is not set, but directly stop member among the embodiment one is removably mounted in the first hole section, and be arranged on bolt head towards a side of LED display modular.Like this, bolt head is limited between stop member and the second hole section equally, and when the dismounting led display unit, bolt head is replaced on stop member, thereby can not contact with the LED display modular, also just can not damage the LED display modular.Stop member also can be installed in the first hole section by other means, also can internal thread be set in the position of the close first surface of the first hole section, and stop member is provided with outside thread, thus stop member and the first hole section screw-thread fit.

The application also provides a kind of LED display system, comprises a plurality of above-mentioned led display units according to the embodiment of the application's LED display system.Above-mentioned led display unit is rectangular distribution, when certain led display unit damage in the LED display system need remove maintenance or change, can carry out disassembling section easily from the front.Like this, make that the maintenance of LED display system is simple more, convenient.In order to make the shown image of LED display system more complete, fit between two adjacent led display units.

The above is preferred embodiment of the present utility model only, is not limited to the utility model, and for a person skilled in the art, the utility model can have various changes and variation.All within spirit of the present utility model and principle, any modification of doing, be equal to replacement, improvement etc., all should be included within the protection domain of the present utility model.
