Description

A kind of for convenience detach and the fixing device that fan is installed

Technical field

The utility model relates to a kind of fixing device, refer to a kind of fixing device of for convenience detach and the kind fan that fan is installed especially.

Background technique

The sink that generally uses at present is fan, because its use is the most convenient and efficient is also the highest, yet because of fan the vibration of start mostly since its inner some is uneven or stressed via the energy that structure sent out, and cause the vibration of fan integral body.

The reason of general fan forced vibration has aftermentioned several: loosening, cunning bad, the damage of bearings of the inadequate balance of uneven strength, revolving meber, parts, electromagnetic action, blade wear, axle be not to factors such as the heart and bending shafts.

So, when the vibration transfer that is ejected when fan inside arrives each corner of fan integral body, rely on the place of inquiring into internal defects in mechanism's outside measurement fan vibration amount in order to improve the noise that fan vibration produces.

Present fan vibration test is that a fan is fixed on the platform, and with the vibration index of measurement fan, and at present general fan means of fixation is as follows:

Mounting hole with the corresponding fan of screw locks it on platform;

Use pneumatic cylinder and anchor clamps utilize air pressure by the outside (opposite side of opposite side, or the left and right sides up and down) clamping of fan on platform;

Hang the mounting hole or the two sided plaster of described fan pastes with fine rule;

Block the fan mounting hole with the wedge type latch.

But above-mentioned have its problem to exist on reality is used, and removing and installing of aforementioned first kind of means of fixation is difficult and time-consuming; Aforementioned second and third kind mode then user mode with fan is different, and actual use condition does not coexist so cause the vibrational mode of measuring (or claiming data); Aforementioned the 4th kind of strength because of fixing is quite big, measures quality and increases man-hour if the fan dismounting then can will be destroyed the mounting hole influence of fan, and it is required really not to be inconsistent the user.

Edge is, because every shortcoming that above-mentioned existing product are derived, the model utility designer of this case exhausts its intelligence then, to be engaged in described industry experience for many years, concentrate on studies and innovated improvement, finally successfully the fixing device case that this part is for convenience detach and fan is installed is finished in research and development, is the model utility that a tool effect is promoted in fact.

Summary of the invention

Embodiment

The utility model provides a kind of for convenience detach and the fixing device that fan is installed, icon is the utility model preferred embodiment, seeing also Fig. 1 shows, described fan 10 has a framework 11, a mounting hole 111 is set up in four corners of framework 11 separately, and framework 11 has a gas channel 112, and described fixing device comprises a pedestal 21, a fixed block 22, a movable part 23 and power plant 24, aforementioned fixation part 22 is installed on the described pedestal 21, and its end face hangs down and establishes at least one first fixing rod group 221; Aforementioned movable part 23 is located at the opposite side of described pedestal 21 and relative aforementioned fixation part 22, and its end face hangs down and establishes at least one second fixing rod group 231.A side of aforementioned fixation part 22 relative movable parts 23 is provided with at least one nose bar 222 in addition.

Aforementioned power plant 24 have at least one drive link 241 and connect a not side of relative fixed part 22 of aforementioned movable part 23, described power plant 24 can for example be a Pneumatic pressure power or spring powered operation, to drive aforementioned movable part 23 relative to described fixed block 22 reciprocal moving.

Consult Fig. 2, Fig. 3 icon in the lump, aforementioned power plant 24 drive described movable part 23 and move to second place B from primary importance A, be that a straight line moves between described primary importance A and second place B, when described movable part 23 moves to second place B place, then the mounting hole 111 in fan 10 4 corners is can be respectively corresponding and wear first and second fixing rod group 221,231 that is positioned at both sides, work as aforementioned movable part 23 in addition and return back to primary importance A from second place B, then aforementioned first and second fixing rod group 221,231 produces a retention force to aforementioned framework 11 in mounting hole 111.

Moreover, the more described second place B of the described primary importance A of expression is relatively away from described fixed block 22 in Fig. 2, Fig. 3 figure, then described movable part 23 returns back to primary importance A place, and aforementioned first and second fixing rod group 221,231 acts on aforementioned framework 111 from the mounting hole 111 interior rightabout retention forces (expansionary force that promptly draws back) that produce; Aforementioned being not limited thereto of thought, though not icon but described primary importance A can more aforementioned second place B relatively near aforementioned fixation part 22, when described movable part 23 returns back to primary importance A place, aforementioned first and second fixing rod group 221,231 acts on aforementioned framework 11 from mounting hole 111 interior generations towards the retention force (i.e. Ya Suo urgent power) of opposite direction, relies on above-mentioned retention force fan 10 is fixed on fixed block 22 and the movable part 23.

Moreover, because of a side of aforementioned fixation part 22 relative movable parts 23 is provided with at least one nose bar 222, so when movable part 23 moves to second place B place, one side of movable part 23 relative fixed parts 22 contacts described nose bar 222, be to keep a contact space C not, the not contact space C that then aforementioned gas channel 12 corresponding fixed blocks 22 and movable part are 23 between fixed block 22 and the movable part 23.

Aforementioned in addition pedestal 21 is provided with at least one through hole 211 correspondences between aforementioned fixation part 22 and aforementioned movable part 23, and then relative with the gas channel 12 of aforementioned framework 11, then can make effluent air discharge from described through hole 211 when fan 10 starts.

Fig. 4 is to shown in Figure 7 in addition, establish at least one guide rail 26 in that aforementioned pedestal 21 and aforementioned movable part 23 are wherein arbitrary, then another is provided with the guide channel 27 that cooperates with described guide rail 24 and (is located on the pedestal 21 at the guide rail described in this figure 26, described guide channel 27 is located on the movable part 23), when described movable part 23 is mobile by power plant 24 drives, follows described guide rail 26 and move back and forth at primary importance A and second place B.

Please consult Fig. 8, shown in Figure 9 in addition again, be another preferable enforcement of the utility model, itself and last preferable enforcement do not exist together and be to omit the setting of nose bar, and establish a blocked part 261 on aforementioned guide rail 26, with block or limit moving of described movable part 23.

Via aforementioned, a kind of fixing-assembly that need not dismantle or lock fan attachment is provided, make described fan assemble more easily or dismantle, and more can meet the assembling kenel of the actual use of fan, to obtain the every test data under the actual behaviour in service of fan.

In sum, a kind of for convenience detach and the fixing device that fan is installed provided by the utility model really meet the important document that grants a patent, and propose patent application in accordance with the law.

More than explanation is novel just illustrative for this; and it is nonrestrictive; those of ordinary skills understand; under the situation of the spirit and scope that do not break away from following claims and limited; can make many modifications; change, or equivalence, but all will fall in the protection domain of the present utility model.
