A shock-proof connection device and a fan with the device

Abstract

A shock-proof connection device and a fan with the same are used to solve the problem that the existing shock-proof connection device is prone to cracks or even broken. The fan of the present invention includes: a housing with at least one air inlet and an air outlet, a chamber in the housing communicates with the at least one air inlet and the air outlet; a fan wheel is accommodated in the chamber; a motor is driven by One of the at least one air inlet or the air outlet extends into the chamber, and has a rotating shaft, and the rotating shaft is combined with the fan wheel; a plurality of shock-absorbing connecting devices, each of which has a first joint part and a second joint part and a damping element, the first joint part is connected to the motor, the second joint part is connected to the casing, the shock resistance element is arranged between the first joint part and the second joint part and completely separates the first joint part A joint part and the second joint part.

Description

technical field [0001] The invention relates to a shock-absorbing connection device and a fan with the same, in particular to a shock-resistance connection device which is easy to install, can effectively block vibration and has better structural strength. Background technique [0002] Please refer to figure 1 As shown, it is a conventional fan casing with a shock-absorbing connection device disclosed in Taiwan Patent No. M531519, wherein the fan casing has an outer frame 8 and a plurality of shock-proof connection devices 9 . Each shock-proof connection device 9 forms a base 91, a covering sleeve 92 and two fixing plates 93 in an integrated manner, and the base 91 is attached to the outer surface of the outer frame 8 and screwed with a plurality of screws 94. Fixed on the outer frame 8, the covering sleeve 92 is used to cover the screw (not shown) that fixes the fan casing at a predetermined position, and one side of the two fixing plates 93 is respectively connected to th...

Problems solved by technology

[0003] However, since the shock-absorbing connecting device 9 is generally made of elastic rubber or plastic material, the overly complicated structure as above can easily weaken the overall structural strength.

In detail, after a period of use, the shock-proof connection device 9 is easy to form a bent position (such as the junction of the base 91 and any fixed plate 93) or a thin-walled perforated position (such as the base 91 at the hole for the screw 94) to produce cracks or even breakage

In addition, due to the above-mentioned complex structure, the shock-resistant connection device 9 is also less tolerant to manufacturing errors (for example: if the hole for the screw 94 to pass is closer to the periphery of the base 91 due to manufacturing errors, it may Make the wall surface between the hole and the periphery of the base 91 more likely to break when being squeezed by the screw 94)
