The beneficial effects of the utility model are：By the bottom of protecting stand is contacted with the upper surface of mainboard, and make The through hole of protecting stand is corresponding with the lead to the hole site on mainboard, and in assembling, screw recycles sealed after initially passing through through hole The sealed rotating shaft of instrument is fastened, and in fastener cycle, even if sealed rotating shaft occurs to depart from screw, sealed rotating shaft also will not It is slipped on mainboard, breaks the components and parts on mainboard, its protected effect is good, and easy to use.

Description of the drawings

In order to be illustrated more clearly that this utility model embodiment or technical scheme of the prior art, below will be to embodiment Or accompanying drawing to be used is briefly described needed for description of the prior art, it should be apparent that, drawings in the following description are only It is some embodiments of the present utility model, for those of ordinary skill in the art, in the premise for not paying creative work Under, can be with according to these other accompanying drawings of accompanying drawings acquisition.

Fig. 1 is the structural representation that intelligent terminal of the present utility model fastens preventer；

Fig. 2 is the sectional view of the protecting stand of intelligent terminal's fastening preventer of the present utility model.

Specific embodiment

Below in conjunction with the accompanying drawings preferred embodiment of the present utility model is described in detail, so that advantage of the present utility model Can be easier to be readily appreciated by one skilled in the art with feature, it is apparent clear and definite so as to make to protection domain of the present utility model Define.

Refering to shown in Fig. 1-2, intelligent terminal of the present utility model fastens preventer, and the intelligent terminal includes 1 He of mainboard Multiple through holes 3 and multiple screwed holes 4 are respectively equipped with housing 2, mainboard 1 and housing 2, through hole 3 and screwed hole 4 are corresponded, it is main Plate 1 and housing 2 are mutually locked with screwed hole 4 through after through hole 3 by screw 5, and the preventer includes protecting stand 6, protecting stand 6 Bottom is contacted with the upper surface of mainboard 1, and the center of protecting stand 6 is additionally provided with pass through aperture 7 from top to down, through hole 7 Position is corresponding with the position of screwed hole 4 to be locked, also including a closure tool 8 with sealed rotating shaft 81, sealed rotating shaft 81 end is engaged with screw 5, and the external diameter of the maximum outside diameter of screw 5 and sealed rotating shaft 81 is respectively less than the minimum of through hole 7 Internal diameter.

This utility model is by the bottom of protecting stand 6 is contacted with the upper surface of mainboard 1, and makes running through for protecting stand 6 Hole 7 is corresponding with 3 position of through hole on mainboard 1, and in assembling, screw 5 recycles closure tool 8 after initially passing through through hole 7 Sealed rotating shaft 81 is fastened, and in fastener cycle, even if sealed rotating shaft 81 occurs to depart from screw 5, sealed rotating shaft 81 is not yet Can be slipped on mainboard 1, break the components and parts on mainboard 1, its protected effect is good, and easy to use.

Specifically, protecting stand 6 includes being oriented to extension block 61 and protection block 62, is oriented to the shape of extension block 61 and protection block 62 Respectively up-small and down-big truncated cone-shaped and cylinder, are oriented to the top that extension block 61 is arranged on protection block 62, protect the bottom of block 62 Portion is contacted with the upper surface of mainboard 1.The guiding extension block 61 of truncated cone-shaped not only can be played and mitigate 6 overall weight of protecting stand Effect, and the effective depth of through hole 7 can be increased, make sealed rotating shaft 81 can extend into the inside of through hole 7, so as to play Prevent the effect of the components and parts of the collision mainboard 1 of sealed rotating shaft 81.The protection block 62 of cylinder is increased and is connect with the upper surface of mainboard 1 Contacting surface is accumulated, and improves the stability during use.
