Description

螺栓组件和空调热泵机组
本申请要求以下中国专利申请的优先权：于2020年05月09日提交中国专利局的申请号为202020763301.0、发明创造名称为“螺栓组件和空调热泵机组”的中国专利申请。上述专利申请的全部内容通过引用结合在本申请中。
技术领域
本公开涉及螺栓领域，特别地，涉及一种改进的防转固定螺栓组件。
背景技术
本部分的内容仅提供了与本公开相关的背景信息，其可能并不构成现有技术。
在空调热泵机组中，通常使用螺栓来对空调热泵机组的各个相关部件进行固定。与氟机空调相比，在空调热泵机组中，内部安装的部件较多、在结构上更为紧凑，因此在使用普通螺栓的情况下，对例如水泵的部件进行安装和维护非常困难。
图1是现有技术的空调热泵机组的动力水泵侧视图，图2是现有技术的空调热泵机组的动力水泵的前视图，图3是现有技术的用于安装动力水泵的螺栓和螺母的示意图。如图1所示，水泵100通过螺栓110安装在空调热泵机组内。如图2所示，水泵100包括本体101和底座102，并且在底座102上设置有用于螺栓110的孔例如多个孔。空调热泵机组包括用于安装水泵的结构板301，并且在结构板301上也设置有相同数量的孔。在安装水泵100时，首先将水泵100的底座102放置在空调热泵机组的结构板301上，并且将水泵100的底座102上的孔与空调热泵机组的结构板301上的相应的孔对准。然后，在水泵100的底座102的孔上分别放置垫片，并且利用如图3所示的螺栓110和螺母120来将水泵100的底座102固定在空调热泵机组的结构板301上以将水泵安装在空调热泵机组中。具体地，在例如采用两个螺栓110时，使它们分别穿过对准的水泵100的底座102上的孔和空调热泵机组的结构板301上的相应的孔，然后将两个如图3所示的螺母120分别旋拧在两个螺栓110上，使得螺母120抵靠在空调热泵机组的结构板301上，从而完成螺栓110的固定，以最终将水泵100安装在空调热泵机组中。由此可知，在水泵100的安装过程中，需要分别 对两个螺栓110进行紧固，并且在安装过程中，需要两个扳手，其中一个扳手用于在旋拧螺母120时防止螺栓110的转动，而另一个扳手用于旋拧螺母120。由于空调热泵机组的结构较为紧凑，内部空间较小，因此在进行上述安装过程中，由于空间的限制，使用两个扳手来通过螺栓安装例如水泵的部件在操作上较为困难，不便于例如水泵的部件的安装和维护。
因此，存在对一种改进的固定螺栓组件的需要，该固定螺栓组件能够实现以更为便利的方式对部件进行安装，使部件的安装和维护更为方便，并且能够实现更加牢固及可靠的部件安装。

具体实施方式
下面参照附图、借助具体实施方式对本公开进行详细描述。对本公开的以下详细描述仅仅是出于说明目的，而绝不是对本公开及其应用或用途的限制。
首先，参照图4-图7描述根据本公开的第一实施方式的防转固定螺栓组件的构型及实际应用。
图4是根据本公开的第一实施方式的防转固定螺栓组件的立体图，其中，从上方观察该防转固定螺栓组件。图5是根据本公开的第一实施方式的防转固定螺栓组件的另一角度的立体图，其中，从下方观察该防转固定螺栓组件。图6是根据本公开的第一实施方式的防转固定螺栓组件的前视图。
如图4-图6所示，根据本公开的第一实施方式的防转固定螺栓组件1包括两个螺栓11、12和将两个螺栓11、12连接在一起的呈长形片状的连接件13，例如钣金连接片。需要注意的是，连接件的长形片状包括在沿着连接件的厚度方向观察时，连接件在连接件的长度方向上笔直地延伸的情况以及连接件在连接件的长度方向上稍微弯折的情况。在图6所示的本公开的第一实施方式中，连接件13构造成：在沿着连接件13的厚度方向(如图6中的上下方向)观察 时，连接件在连接件的长度方向(如图6中的左右方向)上笔直地延伸。在连接件13的两个端部部段设置有供两个螺栓11、12穿过的两个孔，并且连接件13的设置有孔的两个端部部段与连接件13的中央部段处于高度相同的平面上(即，在沿着连接件的宽度方向——即如图6中的纸面方向——观察时，连接件13呈平直状)。螺栓11、12分别穿过连接件13中相应的孔并且通过例如焊接或铆接等的固定方式与连接件13固定在一起。特别地，螺栓11、12穿过连接件13中的孔，使得螺栓11、12的头部抵靠呈长形片状的连接件13的一侧表面。由此，可以容易地在螺栓11、12的头部与连接件13的该一侧表面之间进行焊接，并且/或者，在螺栓11、12的柱状部的位于孔中的部分与孔之间进行焊接。例如，螺栓11、12可以是电阻焊接螺栓，并且通过电阻焊接而与连接件13固定在一起。螺栓11、12均具有头部和柱状部，并且在柱状部上设置有螺纹。需要注意的是，防转固定螺栓组件1的螺栓11、12的规格、连接件13的尺寸以及连接件13的用于螺栓11、12的孔的位置可以根据情况而改变。在图示的示例中，连接件13构造成：在沿着连接件13的厚度方向(如图6中的上下方向)观察时，连接件在连接件的长度方向(如图6中的左右方向)上笔直地延伸。由于连接件13具有在沿厚度方向观察时在长度方向上笔直地延伸的形状，与连接件弯折地延伸的相关方案相比，笔直延伸的连接件可以使螺栓组件本身的结构更加简单并且使螺栓组件本身的结构更加牢固。
图7是使用根据本公开的第一实施方式的防转固定螺栓组件安装的动力水泵的示意图。如图7所示，动力水泵2包括本体21和底座22，并且在底座上设置有供螺栓穿过的孔，例如两个孔。空调热泵机组包括用于安装动力水泵2的结构板31，并且在结构板31上也设置有用于螺栓的相同数量的孔，例如两个孔。在安装动力水泵2时，首先将动力水泵2的底座22放置在空调热泵机组的结构板31上，并且将动力水泵2的底座22上的孔与空调热泵机组的结构板31上的相应的孔对准。然后，使用防转固定螺栓组件1来将动力水泵2安装到空调热泵机组的结构板31上。例如，使用一个防转固定螺栓组件1来安装该动力水泵2。具体地，使防转固定螺栓组件1的螺栓11、12分别穿过对准的动力水泵2的底座22上的两个孔和结构板31上的相对应的两个孔，从而使防转固定螺栓组件1的下表面抵靠在动力水泵2的底座22的上表面上。然后将两个螺母分别从下方旋拧到防转固定螺栓组件1的两个螺栓11、12的柱状部上，最终使螺母紧紧抵靠空调热泵机组的结构板31的下表面以固定防转固定螺栓组件1，从而完成动力水泵2的固定和安装。
在上述安装过程中，由于根据本公开的第一实施方式的防转固定螺栓组件1的螺栓11、12和连接件13已经固定在一起，因此在拧紧螺母的过程中，仅需要一个扳手，而不需要另一个扳手来防止螺栓11、12的转动。而且，由于防转固定螺栓组件1的螺栓11、12可以是电阻焊接螺栓，并且通过电阻焊接与连接件13固定，因此可以实现防转固定螺栓组件1的快速和批量生产，并且使得防转固定螺栓组件1的成本较低。此外，由于使用了防转固定螺栓组件1，还可以在安装过程中省去垫片，进一步简化了安装过程。由此可见，通过使用根据本公开的第一实施方式的防转固定螺栓组件，可以大大提高了在结构较为紧凑的机组、例如空调热泵机组中安装诸如动力水泵的部件的便利性，并且还利于对诸如水泵的部件进行维护和拆卸。另外，与例如螺栓与连接件之间通过形状配合方式进行连接以限制螺栓的旋转的相关技术相比，在根据第一实施方式的防转固定螺栓组件1中，由于连接件与螺栓例如通过焊接或铆接而固定地连接，因此也限制了螺栓相对于连接件的其他运动，从而能够确保更加牢固及可靠的部件安装。
在下文中，将参照图8-图11描述根据本公开的第二实施方式的防转固定螺栓组件的构型及实际应用。
图8是根据本公开的第二实施方式的防转固定螺栓组件的立体图，其中，从上方观察该防转固定螺栓组件。图9是根据本公开的第二实施方式的防转固定螺栓组件的另一角度的立体图，其中，从下方观察该防转固定螺栓组件。图10是根据本公开的第二实施方式的防转固定螺栓组件的前视图。
如图8-图10所示，根据本公开的第二实施方式的防转固定螺栓组件10包括两个螺栓14、15和将两个螺栓14、15连接在一起的呈长形片状的连接件16，例如钣金连接片。在连接件16的两个端部部段17、18中设置有供两个螺栓14、15穿过的两个孔。螺栓14、15分别穿过连接件16中相应的孔并且通过例如焊接或铆接等的固定方式与连接件16固定在一起。例如，螺栓14、15可以是电阻焊接螺栓，并且通过电阻焊接而与连接件16固定在一起。螺栓14、15均具有头部和柱状部，并且在柱状部上设置有螺纹。根据第二实施方式的防转固定螺栓组件10与根据第一实施方式的防转固定螺栓组件1的不同之处在于，连接件16具有凸台形状、即连接件16的中央部段和两个端部部段17、18处于高度不同的平面上。换言之，在沿着连接件的宽度方向——即如图10中的纸面方向——观察时，连接件16呈中间隆起的凸台状。如图10所示，中 央部段相对于两个端部部段17、18朝向上侧隆起，亦即，朝向连接件16的与螺栓的头部所处位置对应的一侧隆起。具体地，连接件16的设置有孔的两个端部部段17、18通过弯曲部段25、26分别与中央部段相连接，从而使得端部部段17、18与中央部段处于高度不同的平面上。例如，连接件16是通过模具冲压而成型的。由于连接件16具有凸台形状，因此可以适应与防转固定螺栓组件10的下表面接触的固定件接触面不平的情况，使得连接件的设置有螺栓的端部部段能够与固定件接触面贴合，从而避免预紧力的下降。需要注意的是，防转固定螺栓组件10的螺栓14、15的规格、连接件16的尺寸和弯曲部段25、26的具体形状，以及连接件16的用于螺栓14、15的孔的位置可以根据情况而改变。
图11是使用根据本公开的第二实施方式的防转固定螺栓组件安装的动力水泵的示意图。如图11所示，动力水泵20包括本体23和底座24，并且底座24的上表面具有凸台形状，其中央部段相对于端部部段向上突起，在底座24的端部部段中设置有供螺栓穿过的孔，例如两个孔。空调热泵机组包括用于安装动力水泵20的结构板32，并且在结构板32上也设置有用于螺栓的相同数量的孔，例如两个孔。在安装动力水泵20时，首先将动力水泵20的底座24放置在空调热泵机组的结构板32上，并且将动力水泵20的底座24上的孔与空调热泵机组的结构板32上的相应的孔对准。然后，使用防转固定螺栓组件10来将动力水泵20安装到空调热泵机组的结构板32上。例如，使用一个防转固定螺栓组件10来安装该动力水泵20。具体地，使防转固定螺栓组件10的螺栓14、15分别穿过对准的动力水泵20的底座24上的两个孔和空调热泵机组的结构板32上的相对应的两个孔。在该实施方式中，防转固定螺栓组件10的连接件16具有与底座24的上表面的凸台形状相配合的凸台形状，使得当防转固定螺栓组件10的连接件16的中央部段抵靠在底座24的中央部段上时，防转固定螺栓组件10的连接件16的端部部段17、18也能够抵靠在底座24的相应的端部部段上，并且在防转固定螺栓组件10的连接件16的端部部段17、18与动力水泵20的底座24的端部部段之间没有间隙。然后，在防转固定螺栓组件10的连接件16的中央部段和端部部段17、18分别抵靠在动力水泵20的底座24的中央部段和端部部段的情况下，将两个螺母分别从下方旋拧到防转固定螺栓组件10的两个螺栓14、15的柱状部上，最终使螺母紧紧抵靠空调热泵机组的结构板32的下表面以固定防转固定螺栓组件10，从而完成动力水泵20的固定和安装。
通过上述描述可知，根据本公开的第二实施方式的防转固定螺栓组件10具有与根据本公开的第一实施方式的防转固定螺栓组件1的优点相同的优点。除此之外，根据本公开的第二实施方式的防转固定螺栓组件10还可以适应具有不同形状的固定件接触面的部件，例如底座呈凸台状的动力水泵。在安装底座呈凸台状的动力水泵的情况下，通过使用根据本公开的第二实施方式的防转固定螺栓组件10，由于该防转固定螺栓组件10具有与动力水泵的底座的上表面的凸台形状相配合的凸台形状，因此可以使防转固定螺栓组件的连接件的下表面与动力水泵的底座的上表面紧密贴合，从而能够更好地保持预紧力，提高固定的可靠性。
此外，需要注意的是，根据本公开的防转固定螺栓组件不仅适用于将动力水泵安装在热泵空调机组中，并且还适用于将其他部件安装在其他结构紧凑的机组的应用中。而且，虽然如前所述，仅使用一个防转固定螺栓组件来完成动力水泵的安装，并且防转固定螺栓组件均包括两个螺栓，但是在根据本公开的防转固定螺栓组件的应用中，可以根据实际需要而使用两个或更多个防转固定螺栓组件来完成各种部件的安装，并且根据本公开的防转固定螺栓组件不限于包括两个螺栓，而是可以包括两个或更多个螺栓。并且，本公开的防转固定螺栓组件的连接件也不限于呈长形片状，而是根据实际需要可以具有各种形状。另外，在上文中，具体描述的是连接件设置有供螺栓穿过的孔以实现螺栓与连接件的固定连接，然而，应当理解的是，连接件也可以不设置有孔而是采用其他合适的方式实现螺栓与连接件的固定连接，例如，使连接件的两端直接地与螺栓的头部焊接。
虽然已经参照示例性具体实施方式对本公开进行了描述，但是应当理解，本公开并不局限于文中详细描述和示出的具体实施方式，在不偏离权利要求书所限定的范围的情况下，本领域技术人员可以对示例性具体实施方式做出各种改变。
