Abstract

The utility model discloses a knockout support, including the support subject who is used for supporting the knockout, it still includes the bump leveller, and the bump leveller includes: connecting rod, quality piece and elastic component. The connecting rod sets up between support subject and knockout, and erect on support subject at the both ends of connecting rod, and quality piece cover is established and can follow the axis direction slip of connecting rod on the connecting rod, carries out spacing and automatic re -setting for the position of confrontation gage block, has set up the elastic component in the both sides of quality piece. Through the aforesaid setting, the quality piece keeps motionless when initial, and trembles the in -process at compressor start -stop machine, and the quality piece changes with support subject relative position, causes the elastic component compressed and the drawing at quality piece both ends. Because elastic component compressed and the tensile change that arouses the elastic force, effort and reaction force, elastic force reverse action effectively prevent the knockout shake on support subject. The utility model also provides an air conditioner that has above -mentioned knockout support.

Accompanying drawing explanation

In order to be illustrated more clearly in the utility model embodiment or technical scheme of the prior art, be briefly described to the accompanying drawing used required in embodiment or description of the prior art below, apparently, accompanying drawing in the following describes is only embodiment of the present utility model, for those of ordinary skill in the art, under the prerequisite not paying creative work, other accompanying drawing can also be obtained according to the accompanying drawing provided.

The structural representation of the knockout support that Fig. 1 provides for the utility model embodiment.

Detailed description of the invention

Core of the present utility model is to provide the utility model and provides a kind of knockout support, to alleviate the vibration of knockout.Another core of the utility model is to provide a kind of air-conditioning with above-mentioned knockout support.

Below in conjunction with the accompanying drawing in the utility model embodiment, be clearly and completely described the technical scheme in the utility model embodiment, obviously, described embodiment is only the utility model part embodiment, instead of whole embodiments.Based on the embodiment in the utility model, those of ordinary skill in the art are not making the every other embodiment obtained under creative work prerequisite, all belong to the scope of the utility model protection.

As shown in Figure 1, the utility model discloses a kind of knockout support, comprise the rack body 2 for supporting knockout 1, it also comprises bump leveller, and this bump leveller specifically comprises: connecting rod 3, mass 5 and elastic component 4.Wherein, connecting rod 3 is arranged between rack body 2 and knockout 1, and the two ends of this connecting rod 3 are erected on rack body 2, above-mentioned mass 5 to be set on connecting rod 3 and can to slide along the axis direction of connecting rod 3, in order to carry out the position of mass 5 spacing and automatically reset, be provided with elastic component 4 in the both sides of mass 5.By above-mentioned setting, time initial, mass 5 keeps motionless, and in compressor startup-shutdown dither process, mass 5 and rack body 2 relative position change, and cause the elastic component 4 at mass 5 two ends compressed and stretch.Compressed due to elastic component 4 and stretch and cause the change of elastic force, according to Newton's third law (active force and reaction force), elastic force acting in opposition, on rack body 2, effectively stops knockout shake.

In specific embodiment, rack body 2 disclosed in the application is U-shaped support body, namely there is the side plate of horizonal base plate and both sides, knockout 1 is erected between two side plates of rack body 2, in order to increase the stability that rack body 2 pairs of knockouts 1 support, the end of two side plates of rack body 2 all has arcwall face, to increase the contact area of rack body 2 and knockout 1.When knockout 1 is erected at after on U-shaped support body, between the base plate of knockout 1 and the base plate of rack body 2, there is space, in order to prevent interfering the work of knockout 1, preferably, between base plate bump leveller being arranged on knockout 1 and rack body 2, other spaces of the air-conditioning that bump leveller also can be avoided to take.

In further embodiment, the axis of this connecting rod 3 is vertical with the axis direction of knockout 1, to absorb the vibrational energy that knockout 1 passed to by compressor as much as possible.In practice, for connecting rod 3 axis also can with the axes intersect of knockout 1, but the vibrational energy along knockout 1 vertical direction can be reduced.

When the intrinsic frequency of knockout 1 can resonate equal or close to when compressor operating frequency and integer frequency thereof, therefore, by basically identical with the intrinsic frequency of knockout 1 for the design of the intrinsic frequency of bump leveller, to make effectiveness in vibration suppression better.

In addition, for the weight of mass 5 and the weight relationships of knockout 1 be: the quality of knockout 3 is m ₁, the quality of mass 5 is m ₂, and meet: 1) μ=m ₂/ m ₁2)

$1.25<1+\frac{\mathrm{\&mu;}}{2}+\sqrt{\mathrm{\&mu;}+\frac{{\mathrm{\&mu;}}^2}{4}}3)---0.8<1+\frac{\mathrm{\&mu;}}{2}-\sqrt{\mathrm{\&mu;}+\frac{{\mathrm{\&mu;}}^2}{4}}.$

In preferred embodiment, above-mentioned elastic component 4 is set to spring, particularly, one end of this spring is connected with mass 5, and the other end and rack body 2 offset, in the provisioning process mass 5 is arranged on the middle part of rack body 2, now the spring of mass 5 both sides is drift, when there is skew in mass 5, the spring of both sides can compress accordingly or stretch, make mass 5 position skew, i.e. the centre-of gravity shift of this knockout support, can alleviate under the effect of inertia force knockout 1 shake phenomenon.

For the mounting means of spring, also one end of spring can be fixed on rack body 2, and the other end and mass 5 offset, or one end of spring is fixed on rack body 2, and the other end is fixed on mass 5.Concrete mounting means for spring can be selected according to different needs, and all in protection domain.

In order to lead to the direction of motion of spring, preferably spring housing can be located on connecting rod 3, in addition, in one embodiment, all counterbore is provided with at the two ends of mass 5, and by the bottom of spring fitting at counterbore, to prevent spring from bending under the effect of the pressure, improve the stability of whole knockout support.

Connecting rod 3 disclosed in the application is screw rod, and through the through hole on rack body 2, then be locked on rack body 2 by nut 6 and pad, merely provide a kind of concrete structure of connecting rod 3 herein, but be not limited in said structure, as long as being fixed on the rod-like structure on rack body 2.

In addition, disclosed herein as well is a kind of air-conditioning, it comprises knockout and knockout support, and this knockout support is the support of knockout disclosed in above-described embodiment, and therefore, the air-conditioning with this knockout support also has above-mentioned all technique effects.

In this description, each embodiment adopts the mode of going forward one by one to describe, and what each embodiment stressed is the difference with other embodiments, between each embodiment identical similar portion mutually see.

To the above-mentioned explanation of the disclosed embodiments, professional and technical personnel in the field are realized or uses the utility model.To be apparent for those skilled in the art to the multiple amendment of these embodiments, General Principle as defined herein when not departing from spirit or scope of the present utility model, can realize in other embodiments.Therefore, the utility model can not be restricted to these embodiments shown in this article, but will meet the widest scope consistent with principle disclosed herein and features of novelty.
