Embodiment
With reference to a kind of Drop-proof protection damping device shown in explanation accompanying drawing 1; there is base plate 12 and be arranged on the mounting plate 7 on this base plate 12 by vibration damper; wherein mounting plate 7 is as the installation base plate of erection unit; this is the general configuration structure of damping device; should note; conceptive; below base plate 12 may not just be mounted in as installed; before and after may being, install; but in this case, no matter which type of mounting type it adopts, and the residing position of base plate is all thought below than mounting plate 7; correspondingly, mounting plate 7 in the above.
Mounting plate 7 in Fig. 1 is arranged on base plate 12 by aviation vibration damper 9, and 9, aviation vibration damper connects and cushioning effect, and aviation vibration damper 9 forms the shock reducing support leg of mounting plate 7 in other words.
As aviation vibration damper 9 will be subject to the impact of fatigue load, after certain time limit, may there is fatigue fracture, if there is no protective gear, will inevitably cause coming off of mounting plate 7, and then the equipment being arranged on mounting plate 7 is dropped.
In the structure shown in Fig. 1, also comprise breaker bolt 8, in base plate 12 or mounting plate 7 is fixed in these breaker bolt 8 one end, and the other end is sliding sleeve default via hole on another, and restrained through degrees of freedom reverse after via hole.
Structurally, the fixed end of breaker bolt 8 can not affect it on mounting plate 7 or base plate 12 to be used, but is preferably fixed on base plate 12.Comparatively speaking, base plate 12 is fixed, and mounting plate 7 is relatively movable, and this mounting structure is more reliable.
As shown in Figure 1, mounting plate 7 and the distance between base plate 12 of breaker bolt 8 constraints are greater than the distance that vibration damper supports, when vibration damper works, breaker bolt 8 can not be subject to load, while only having vibration damper to break down, breaker bolt 8 just can work, and guarantee breaker bolt 8 is in the controlled state of safety like this.
As shown in Figure 3, constraint breaker bolt 8 is that breaker bolt is furnished with thread section at this end through the restraining structure of reverse degrees of freedom after via hole, as the upper end on Fig. 3 b, is one section of screw thread, thereby retrains by nut through after via hole, and this structure is also for convenience detach.
Preferably, described breaker bolt disposes a plurality of, and take mounting plate 7 center as benchmark circumferentially uniform, this layout is conducive to symmetrical load, after defective shock absorber, can maintain relatively preferably equipment installment state, at short notice as watch-dog still can normally use.
Further, the number of described breaker bolt is 2 ~ 4, and in actual use, minimum should be furnished with 3, according to load, can also join and only have as the even numbers such as 6,8,10.But breaker bolt is mainly interim effect, should not configures too much, otherwise can increase unnecessary expenditure.Especially breaker bolt price is relatively high.
Described vibration damper is aviation vibration damper 9, and as the aviation vibration damper that Liaoyang aviation vibration damper Co., Ltd is produced, level of integration is higher, and mounting structure is succinct.
Nature, vibration damper plays and connects and cushioning effect, by the guide pillar of simple spring and cooperation, can construct, and those skilled in the art will readily understand.Therefore, the selection of vibration damper can be selected according to concrete cost control and structure aesthetic property.
The seat end of described vibration damper is fixed on described base plate 12, and head end is connected in the default hole on mounting plate 7, and its configuration structure as shown in Figure 4, as the connection of stainless steel socket head screw 4 is perfectly clear in the drawings, does not repeat them here in figure.
Described default hole is furnished with the screw cover 6 coordinating with this hole, default hole axle, and the upper end of this screw cover 6 is with bead, thereby screw cover is supported in the upper surface of mounting plate by this bead.Prevent mounting hole and screw direct collision friction on mounting plate, avoid causing the relatively serious problem of mounting hole wearing and tearing on mounting plate.
As shown in Figure 2, described mounting plate 7 has lightening hole, alleviates whole weight, and simultaneously based on same considering, as shown in Figure 6, base plate 12 also has lightening hole.
Preferably, described lightening hole comprises center lightening hole and the periphery lightening hole that is distributed in center lightening hole periphery, and clean and tidy structure aesthetic property is relatively good, and this distributed architecture can too much not reduce the structural strength of plate body part.
The utility model can pass through or adopt existing techniques in realizing without the technical characteristics of describing; do not repeat them here; certainly; above-mentioned explanation is not to restriction of the present utility model; the utility model is also not limited in above-mentioned giving an example; the variation that those skilled in the art make in essential scope of the present utility model, remodeling, interpolation or replacement, also should belong to protection domain of the present utility model.
