现有市场上，在一些推拉门窗(例如壁柜门窗)上通常会设置阻尼器来起到缓冲作用，在门页或窗页开启或者关闭时，通过阻尼器辅助开启或关闭，从而减轻碰撞和降低噪音。
现有技术中公开了一种可用于双向阻尼系统的阻尼器(专利号为201721125021.1)，其壳体的侧面开设有导向槽，拨动块的两侧具有向外凸起的导向块，通过导向槽和导向块的配合，形成拨动块的导向结构。经过长时间的实际应用，发现上述结构存在以下严重缺陷和不足：
①、该阻尼器结构需要在壳体的中部开设导向槽，从而导致壳体通常只能由钣金件加工形成，而钣金件相对于其它材料而言，结构强度较低，在使用时间长后难以避免变形。若采用其它材料加工，则加工工艺过于复杂，成本极高，生产效益极低，无法作为常规用材来实际使用；
②、该阻尼器结构由于需要将带导向块放置入导向槽内，因此在生产过程中需要将壳体分开两半加工形成，在将拨动块放置入两半壳体中，再将两半壳体组装组合。而将两半壳体对准组合，对组装工艺要求极高，组装过程中报废率极高。另外，结合上述第①点，通过两半钣金组装形成的壳体也会更容易发生结构变形现象；
③、该阻尼器结构为了使拨动块到达导向槽的端部位置时快速下沉，以实现快速脱钩动作，以及在拨动块脱钩时，保持拉伸弹簧的拉伸状态， 故在导向槽的端部设有接近垂直的拐角，从而使拨动块到达导向槽的端部位置时下沉，且避免拉伸弹簧带动拨动块回移。但是，由于该拐角过于接近垂直，会导致难以将拨动块重新向内侧拨动，而若不设置该拐角或拐角不够垂直，则无法起到拨动块快速下沉以及避免拨动块回移的作用。
因此，现有技术中亟需发明一种能够克服以上缺陷的推拉门窗用的阻尼器。

进一步地，所述盒体的内部还设有第一弹性件，所述第一弹性件用于为所述限位端提供朝向所述拨动块方向的弹性作用力。
进一步地，所述第二限位件通过第二转轴可转动地设置于所述盒体的内部，所述限位端和所述控制端分别位于所述第二转轴的两侧；
其中，所述第一弹性件为压缩弹簧，所述第一弹性件的一端和所述盒体相抵接，另一端和所述限位端连接；
或者，所述第一弹性件为扭簧，所述第一弹性件套设在所述第二转轴上，且作用于所述第二限位件。
进一步地，所述第一弹性件为压缩弹簧，所述限位端与所述第一弹性件连接的一端设有凸起结构，且所述凸起结构插入所述第一弹性件内。
该推拉门窗用的新型阻尼器公开以上第一弹性件，可在第二限位件的控制端不和壳体的端部接触时，使第二限位件的限位端在第一弹性件的弹性作用力下朝拨动块方向转动，并最终和向上转动的拨动块相抵接，使拨动块在限位端的作用力下保持在盒体的上方位置。
进一步地，所述拨动块设有第一限位槽，当所述限位端和所述拨动块相抵接时，所述限位端卡设在所述第一限位槽中，以限制所述拨动块转动。
进一步地，所述拨动块设有第二限位槽，当所述第一限位件和所述拨动块相抵接时，所述第一限位件卡设在所述第二限位槽中，以限制所述盒体在所述壳体的内部移动。
该推拉门窗用的新型阻尼器通过公开以上两个限位槽结构，可分别用于实现拨动块和第一限位件之间、拨动块和第二限位件之间更好的结构配合效果。
进一步地，所述拨动块上设有限位轴，所述盒体设有第二轨道，所述 限位轴可滑动地设置在所述第二轨道中，所述第二轨道用于为所述拨动块以所述第一转轴为中心做旋转运动提供导向作用。

综上所述，本发明提供的推拉门窗用的新型阻尼器相比于现有技术，至少具有以下技术效果：
1)本发明提供的推拉门窗用的新型阻尼器，通过将盒体、拨动块等结构可滑动地设置在壳体的内部，从而无需在壳体上开设导向槽，可采用钣 金件以外的其他高强度、高性能材料作为壳体材料，实现壳体的结构和用材的升级，整体结构强度高、稳定性好，避免在长时间使用的情况下导致壳体发生结构变形现象。
2)本发明提供的推拉门窗用的新型阻尼器，进一步地，由于无需设置导向块和导向槽等结构，故无需将壳体分开两半加工，可直接在生产过程中一体加工形成，更容易控制整体结构的精度，同时极大地简化了阻尼器的组装工艺，不易在装配过程中出现报废现象，且一体加工形成的壳体结构强度更高，进一步避免其在长期使用的情况下发生结构变形现象。
3)本发明提供的推拉门窗用的新型阻尼器，通过在壳体的内部设置第一限位件和第二限位件，当第二限位件的控制端和壳体的端部接触时，限位端远离拨动块，拨动块在重力作用下以第一转轴为中心向下转动(也即下沉)，并转动至和该第一限位件相抵接，此时拨动块在第一限位件的阻挡作用下无法移动，从而避免拨动块在拉伸弹簧的作用力下发生回移现象，该结构设计方式无需设置导向槽的垂直拐角段，从而避免由于拐角段过于接近垂直而导致难以将拨动块重新向内侧拨动的技术问题。
4)本发明提供的推拉门窗用的新型阻尼器，通过在壳体的内部设置第一限位件和第二限位件，当第二限位件的控制端不和壳体的端部接触时，限位端在第一弹性件的作用力下靠近拨动块，拨动块在阻尼拨动块a的作用力下以第一转轴为中心向上转动并和限位端抵接，在限位端的作用力下保持在上方位置且无法向下转动。

具体实施方式
为了更好地理解和实施，下面将结合本发明实施例中的附图，对本发明实施例中的技术方案进行清楚、完整地描述。
在本发明的描述中，需要说明的是，术语“上”、“下”、“前”、“后”、“左”、“右”、“竖直”、“水平”、“顶”、“底”“内”、“外”等指示的方位或位置关系为基于附图所示的方位或位置关系，仅是为了便于描述本发明和简化描述，而不是指示或暗示所指的装置或元件必须具有特定的方位、以特定的方位构造和操作，因此不能理解为对本发明的限制。
除非另有定义，本文所使用的所有的技术和科学术语与属于本发明的技术领域的技术人员通常理解的含义相同。本文中在本发明的说明书中所使用的术语只是为了描述具体的实施例的目的，不是旨在限制本发明。
实施例1
参见图1-图5所示，在本发明的第一个实施例中，该推拉门窗用的新型阻尼器包括壳体1和盒体2，该盒体2可移动地设置在壳体1的内部，壳体1的内部还设有第一限位件4。其中，壳体1用于固定安装在推拉门的门体上，在门页开启或关闭时起到减轻碰撞和噪音的效果。盒体2可沿壳体1的长度方向在其内部移动，盒体2内用于设置拨动块3、第二限位件5等， 也即盒体2用作以上结构的承载部件，以此实现拨动块3、二限位件5等结构在壳体1的长度方向移动。
该推拉门窗用的新型阻尼器还包括拨动块3和第二限位件5，该盒体2的内部设有第一转轴6和第二转轴7。其中，拨动块3通过第一转轴6可转动地设置在盒体2的内部，第二限位件5通过第二转轴7可转动地设置在盒体2的内部。具体来说，第一转轴6和第二转轴7均沿壳体1的宽度方向设置，分别用于实现拨动块3和第二限位件5在盒体2内部的旋转运动。更为具体来说，第二限位件5包括设置于第二转轴7两侧的限位端51和控制端52，当盒体2朝向壳体1的端部移动，且使控制端52和壳体1的端部接触时，控制端52朝靠近拨动块3的方向转动，则限位端51朝远离拨动块3的方向转动，也即远离拨动块3。相反地，控制端52不和壳体1的端部接触时，控制端52朝远离拨动块3的方向转动，则限位端51朝靠近拨动块3的方向转动，也即靠近拨动块3。
在该实施例的技术方案中，通过在壳体1的内部设置第一限位件4和第二限位件5，可实现拨动块3两种状态的切换，具体如下：
①、当盒体2位于壳体1的端部时，第二限位件5的控制端52和壳体1的端部的物体接触时，限位端51远离拨动块3，拨动块3在重力作用下以第一转轴6为中心向下转动(也即下沉)，并转动至和该第一限位件4相抵接，此时拨动块3在第一限位件4的阻挡作用下无法移动，从而避免拨动块3发生回移现象；
②、当盒体2不位于壳体1的端部时，第二限位件5的控制端52不和壳体1的端部接触时，限位端51靠近拨动块3，拨动块3在阻尼拨动块a的作用力下以第一转轴6为中心向上转动并和限位端51抵接，拨动块3在限位端51的作用力下保持在上方位置，且无法向下转动。
因此，在该实施例中通过设置第一限位件4来实现避免拨动块3发生回移的作用，无需设置背景技术中所述的导向块、导向槽及其垂直拐角段， 也即可避免导向槽的拐角过于接近垂直导致难以将拨动块重新向内侧拨动等技术问题，结构设计简单合理。
更为具体来说，本发明通过将盒体2、拨动块3等结构可滑动地设置在壳体1的内部，实现推拉门窗用的新型阻尼器的缓冲减震功能，从而无需在壳体1上开设导向槽，也即可采用钣金件以外的其他高强度、高性能材料作为壳体1的材料，实现壳体1在结构和用材上的升级，整体结构强度高、稳定性好，避免在长时间使用的情况下导致壳体1发生结构变形现象。并且，由于无需设置背景技术中所述的导向块和导向槽等结构，故无需将壳体1分开两半加工，可直接在生产过程中一体加工形成，更容易控制壳体1的整体结构的精度，同时极大地简化了该新型阻尼器的组装工艺，不易在装配过程中出现报废现象，且一体加工形成的壳体1的结构强度更高，进一步避免其在长期使用的情况下发生结构变形现象。
其中，本发明的壳体1优选采用具有质量轻、成型优、强度高、耐腐蚀、寿命长、可再生、少污染、维护费低等多种优点的一体拉伸成型的铝型材形成。
在该实施例中，推拉门窗用的新型阻尼器的工作过程和工作原理具体如下：
a、进行关门操作前，参见图6的第一个附图所示，该推拉门窗用的新型阻尼器的初始状态为：盒体2靠近壳体1的端部设置，且第二限位件5的控制端52和壳体1的端部接触，限位端52远离拨动块3，拨动块3和壳体1内部的第一限位件4相抵接，拨动块3无法在拉伸弹簧的作用力下回移。
b、当进行关门操作时，参见图6的第二个和第三个附图所示，该推拉门窗用的新型阻尼器随着门体朝门框侧边的方向移动，即图中向左移动，拨动块3和阻尼拨动块a(阻尼拨动块a位于导轨上，位置固定)接触，并在其作用力下朝向远离壳体1的左端端部移动，此时和拨动块3连接的阻 尼管9起到缓冲减震作用，同时拨动块3以第一转轴6为中心向上转动，盒体2上的第二限位件5也朝向远离壳体1的左端端部移动，第二限位件5的控制端52不再和壳体1的端部的物体接触，限位端52朝靠近拨动块3的方向转动，使拨动块3和限位端51相抵接，在限位端51的作用力下无法向下转动，从而将拨动块3保持在盒体2的上方位置。
c、当门体完全关闭时，参见图6的第四个附图所示，盒体2滑动至壳体1的中间部分区域，阻尼拨动块a卡设在拨动块3的顶部，盒体2固定在壳体1的该位置，且拨动块3保持在盒体2的上方位置。
d、进行开门操作时，参见图7的四个附图所示，该推拉门窗用的新型阻尼器随着门体朝远离门框侧边的方向移动，即图中向右移动，拨动块3在阻尼拨动块a的作用力下朝向壳体1的左端端部移动，当盒体2移动至壳体1的端部时，第二限位件5的控制端52和壳体1的端部的物体接触，使第二限位件5另一端的限位端52远离拨动块3，拨动块3失去限位端52的作用力后，受重力作用向下转动至和壳体1内部的第一限位件4相抵接，此时拨动块3在第一限位件4的阻挡限位作用下可避免其在拉伸弹簧10的作用力下回移，恢复为初始状态。
更为具体来说，本实施例中所述的壳体1的端部的物体可以为该推拉门窗用的新型阻尼器的滑轮结构，也可以为壳体1端部的刚性结构，在本发明的实施例中不做具体限定。
参见图2所示，在该实施例的其中一个优选方案中，盒体2的内部还设有第一弹性件8，第一弹性件8用于为限位端51提供朝向拨动块3方向的弹性作用力。在该优选技术方案中，当第二限位件5的控制端52不和壳体1的端部的物体接触时，第二限位件5的限位端51在第一弹性件8的弹性作用力下朝拨动块3方向转动，并最终和向上转动的拨动块3相抵接，使拨动块3在限位端51的作用力下保持在盒体2的上方位置。
参见图2和图4所示，在该实施例的另一个优选方案中，第一弹性件8 为压缩弹簧，限位端51朝向弹簧的一端设有凸起结构53，且凸起结构53插入弹簧设置，以使限位端51和弹簧连接在一起。具体而言，在该实施例中的第一弹性件8采用弹簧结构，且为了适配于该弹簧结构，在限位端51朝向弹簧的一端设置凸起结构53，该凸起结构53插入弹簧中，从而将二者连接在一起，使限位端51在控制端52不接触壳体1的端部的物体时，在弹簧的作用力下朝拨动块3方向转动。
另外，在该实施例的另一个优选方案中，第一弹性件8为扭簧，第一弹性件8套设在第二转轴7上，且作用于第二限位件5，通过扭簧的作用，使得第二限位件5起到与上一优选方案中相同的作用，使限位端51在控制端52不接触壳体1的端部的物体时，在扭簧的作用力下朝拨动块3方向转动。
实施例2
在本发明的第二个实施例中，该推拉门窗用的新型阻尼器公开了两个限位槽结构，分别用于实现拨动块3和第一限位件4之间、拨动块3和第二限位件5之间更好的配合效果。
参见图2和图4所示，在该实施例的其中一个可选方案中，拨动块3朝向第二限位件5的一端设有第一限位槽31，当限位端51和拨动块3相抵接时，限位端51卡设在第一限位槽31中，从而限制拨动块3以第一转轴6为中心向下转动。在该实施例的技术方案中，第一限位槽31具体为设置在拨动块3朝向限位端51的端部、且朝向拨动块3内侧凹进所形成的凹槽结构，限位端51为第二限位件5朝向拨动块3方向凸出所形成的较为细小的凸起结构。当拨动块3在阻尼拨动块a的作用力下以第一转轴6为中心向上转动时，限位端51卡在第一限位槽31中，使拨动块3和第二限位件5相配合，阻挡拨动块3向下转动并保持拨动块3在盒体2的上方位置。
参见图1和图4所示，在该实施例的另一个可选方案中，拨动块3设 有第二限位槽32，当第一限位件4和拨动块3相抵接时，第一限位件4卡设在第二限位槽32中，从而限制拨动块3在壳体1的内部移动。在该可选技术方案中，第二限位槽32具体为设置在拨动块3的底部、且朝向拨动块3的内侧凹进所形成的凹槽结构，当拨动块3以第一转轴6为中心向下转动时，第一限位件4卡在第二限位槽32中，使拨动块3和第一限位件4相配合，从而阻挡拨动块3在拉伸弹簧的作用力下回移。
更为具体来说，第二限位槽32的开口大小大于或等于第一限位件4，以确保其能够容纳第一限位件4。
实施例3
在本发明的第三个实施例中，该推拉门窗用的新型阻尼器公开了两个轨道结构，分别用于为拨动块3位于盒体2内和盒体2位于壳体1内的运动轨迹提供导向、限位作用。
参见图1和图4所示，在该实施例的一个可选方案中，拨动块3上设置有限位轴33，盒体2设有第二轨道21，限位轴33可滑动地设置在第二轨道21中，第二轨道21用于为拨动块3以第一转轴6为中心做旋转运动提供导向作用。在实施例的技术方案中，第二轨道21具体为设置在盒体2在其宽度方向两侧的互为对称的弧形孔，拨动块3上的限位轴33的两端分别插入该两个弧形孔设置，并可滑动地设置在该两个弧形孔中，从而确保拨动块3以第一转轴6为中心做旋转运动的运动轨迹不发生偏移，也即起到导向、限位作用。
参见图1和图5所示，在该实施例的另一个可选方案中，壳体1的内部设有沿壳体1的长度方向延伸的第一轨道11，盒体2可滑动地设置在第一轨道11上，第一轨道11用于为盒体2在壳体1的内部移动提供导向作用。在该可选技术方案中，第一轨道11具体为设置在盒体1内部两侧壁上的互为对称的轨道结构，盒体2可滑动地设置在该两个轨道结构上，从而 确保盒体2沿壳体1的长度方向做直线运动的运动轨迹不发生偏移，也即起到导向、限位作用。
实施例4
参见3和图5所示，在本发明的第四个实施例中，该推拉门窗用的新型阻尼器还包括阻尼管9，该阻尼管9设置于壳体1的内部，盒体2、拨动块3、第一限位件4和第二限位件5的数量均为两个，阻尼管9的两端分别和该两个拨动块3直接连接，或通过两个盒体2与分别和该两个拨动块3间接连接。在该实施例的技术方案中，推拉门窗用的新型阻尼器设有两组盒体2、拨动块3、第一限位件4和第二限位件5，可实现推拉门或窗在其两侧门框的双向缓冲减震功能，具体原理如下：
如图5所示，当朝左边门框方向关门时，推拉门窗用的新型阻尼器会跟随门体一起朝左运动时，移动到一定位置，阻尼器上的拨动块3将会遇到阻尼拨动块a的阻挡，使得拨动块3无法相对于阻尼拨动块a继续移动，而壳体1则跟随门体在惯性的作用下继续朝左边门框方向移动，此时阻尼管9即可发生阻尼缓冲减震作用，使得门体移动速度不至于过快，并缓慢地靠近左边门框。
同样的原理，当朝右边门框方向关门时，推拉门窗用的新型阻尼器会跟随门体一起朝右运动时，移动到一定位置，阻尼器上的拨动块3将会遇到阻尼拨动块a的阻挡，使得拨动块3无法相对于阻尼拨动块a继续移动，而壳体1则跟随门体在惯性的作用下继续朝右边门框方向移动，此时阻尼管9即可发生阻尼缓冲减震作用，使得门体移动速度不至于过快，并缓慢地靠近右边门框。
因此，本发明通过仅设置两组盒体2、拨动块3、第一限位件4和第二限位件5，即可实现双向阻尼系统的功能，结构设计简单合理，成本也更加低廉。更为具体地，两组盒体2之间的距离可调整，或者门框顶部的阻尼 拨动块a之间的距离可根据实际需求调整，用于适应相应的门体或窗的宽度，以此提高产品的适应性。
在使用推拉门阻尼器过程中，关门时阻尼器将跟随门体一起向门框移动，当移动到一定位置时，阻尼器中的拨动块3会遇到阻尼拨动块a的阻挡，此时阻尼器中的阻尼管9发生阻尼缓冲作用，使得门体移动速度不至于过快，并缓慢地靠近门框。但这样的结构设计方式不可避免会产生以下
技术问题：
在关门过程中，由于阻尼管9的缓冲作用，门体的移动速度将被逐渐削弱，但由于不同型号的门体的重量各不相同，当门体较重或者关门时门体移动的速度本来就比较慢时，会导致出现门体速度虽已被削弱为零(也即停止移动)，但门体仍然没有到达门框的情况发生，这样就会造成门关不严实，严重影响用户的使用体验。
因此，为解决该技术问题，该实施例公开了以下优选方案：
参见3和图5所示，该推拉门窗用的新型阻尼器还包括第二弹性件10，该第二弹性件10设置于壳体1的内部，第二弹性件10的两端分别和两个拨动块3连接，且第二弹性件10和阻尼管9相互平行设置。在该优选技术方案中，当拨动块3被阻尼拨动块a阻挡，且阻尼管9发挥阻尼缓冲减震作用时，第二弹性件10在自身拉力的作用下，可以拉动门体继续往门框方向移动，从而避免门关不严的情况发生。
更为具体来说，以上实施例中所述的第二弹性件10采用可拆卸的结构设计方式，或者该第二弹性件10的拉力大小可调整，使拆卸更换后的第二弹性件10或者调整拉力大小后的第二弹性件10和门体的重量相适应，进一步提高该新型阻尼器的适应性。
在该实施例的另一个优选方案中，所述第二弹性件10为拉伸弹簧，所述拉伸弹簧用于为两个所述拨动块3提供方向相反的弹性作用力。具体而言，由于该拉伸弹簧的两端分别和该新型阻尼器的两个拨动块3连接，故 当门体朝向左侧关门时，拉伸弹簧为左侧的拨动块3提供弹性拉力；当门体朝向右侧关门时，伸弹簧为右侧的拨动块3提供弹性拉力，最终起到拉动门体继续移动的效果。
更为具体来说，由于该新型阻尼器设有左右两个拨动块3，故拉伸弹簧无需直接或间接通过其他辅助连接机构和壳体1连接，拉伸弹簧在该推拉门窗往左或者往右移动时，均可起到继续拉动门窗移动的作用，避免门窗没关严。
综上所述，本发明提供的推拉门窗用的新型阻尼器，无需在壳体1上开设导向槽，故可采用钣金件以外的其他高强度、高性能材料作为壳体1材料，整体结构强度高、稳定性好，避免在长时间使用的情况下导致壳体1发生结构变形现象。进一步地，由于无需设置导向块和导向槽等结构，故无需将壳体1分开两半加工，可直接在生产过程中一体加工形成，可极大地简化本发明的阻尼器的组装工艺，不易在装配过程中出现报废现象，且一体加工形成的壳体1结构强度更高，进一步避免其在长期使用的情况下发生结构变形现象。
并且，本发明提供的推拉门窗用的新型阻尼器，通过在壳体1的内部设置第一限位件4来替代导向槽的垂直拐角段，当拨动块3以第一转轴6为中心向下转动(也即下沉)，并转动至和该第一限位件4相抵接时，拨动块3在第一限位件4的阻挡作用下无法移动，从而避免拨动块3在拉伸弹簧的作用力下发生回移现象。此外，该推拉门窗用的新型阻尼器还通过在盒体2的内部设置可转动的第二限位件5来实现拨动块两种使用状态的切换，其具体原理为：当拨动块3移动至壳体1的端部的物体时，第二限位件5的控制端52接触到壳体1端部，使限位端51远离拨动块3，此时拨动块3可转动至和第一限位件4相抵接，避免拨动块3发生回移现象；将拨动块3向上升起，使第二限位件5的限位端重新和拨动块3相抵接，此 时拨动块3在第一弹性件8的作用力下保持在上方位置无法转动，使盒体2在壳体1的内部恢复为可移动状态。
值得一提的是，本发明的新型阻尼器可应用于推拉门、推拉窗或其他推拉型门窗产品，为避免赘述，在以上四个实施例中，统一通过“门体”、“门页”等术语指代多种推拉型门窗产品的门体或窗体结构。
本发明方案所公开的技术手段不仅限于上述实施方式所公开的技术手段，还包括由以上技术特征任意组合所组成的技术方案。应当指出，对于本技术领域的普通技术人员来说，在不脱离本发明原理的前提下，还可以做出若干改进和润饰，这些改进和润饰也视为本发明的保护范围。
