简易安装的制动机构及采用该制动机构的升降立柱 技术领域
本发明涉及升降立柱技术领域，尤其是一种简易安装的制动机构及采用该制动机构的升降立柱。
背景技术
自动升降桌一般是以电为动力来源，通过电动机控制机械装置来调节升降桌的高低，也可以通过压缩机控制气压棒或液压棒来调节升降桌的高度。此类升降桌有单柱及双柱形式，升降方式有遥控及手控两种。自动升降桌在实际使用时需要可靠的自锁机构，这样就不会出现下滑现象。
公告号为CN210265590U的专利公开了一种升降柱的摩擦自锁机构，包括摩擦件和连接件，摩擦件和连接件分别位于驱动盒的内外两侧，驱动端通过摩擦件和连接件的轴向限位作用与升降柱的驱动盒可旋转地装配在一起，摩擦件作用在驱动盒的外侧面上，提供用于实现自锁的摩擦力。该专利的缺点是自摩擦力随着重力的增加会逐渐变大，并且摩擦阻力是双向的，会损耗驱动电机的性能。
公告号为CN208532163U的专利公开了一种传动装置，包括中空心轴，中空心轴内设有传动螺杆，还包括对传动螺杆制动的第一制动扭簧，和对中空心轴制动的第二制动扭簧。该专利的缺点是结构比较复杂，安装不方便，虽然提供了单向的摩擦力，但是在启动时很难做到两条升降立柱的阻力值接近，容易造成抖动。
公告号为CN212878226U的专利公开了一种转轴止动结构，其包括止动组件 和转轴，止动组件设置于转轴上，止动组件包括限位件和扭簧，扭簧套设于所述转轴一端的柱面上，限位件用于限制所述扭簧的一端。该专利的缺点同样是结构复杂，安装不方便，虽然提供了单向的摩擦力，但是在启动时很难做到两条升降立柱的阻力值接近，容易造成抖动。
故现需要解决的技术问题是：1.两只及以上升降立柱在启动时，升降阻力不趋近一致会引起升降桌的抖动；2.现有摩擦结构的阻力值与负载成比例增加，导致驱动电机效率损耗过大；3.现有的制动机构要分别从盒体两个方向进行安装，不能检测装配后的制动机构是否到位；4.电机本身的振动通过连接部件传递至升降立柱，导致振动增加。

具体实施方式
现在结合附图和优选实施例对本发明作进一步详细的说明。这些附图均为简化的示意图，仅以示意方式说明本发明的基本结构，因此其仅显示与本发明有关的构成。
实施例一
如图1所示，本实施例的简易安装的制动机构，包括第一连接件4、安装座5和第二连接件7，第一连接件4部分穿过安装座5，并限位于第二连接件7内，第一连接件4、安装座5和第二连接件7被轴向固定，形成一个整体后安装在盒体121内；安装座5与盒体121保持静止，第一连接件4和第二连接件7相对安装座5可以同步圆周转动。实现第一连接件4、安装座5和第二连接件7的固定方式可以是紧固螺钉、自攻螺钉或其他同等技术手段，例如，采用紧固螺钉1和螺母9，螺母9内嵌于第二连接件7中，紧固螺钉1依次穿过第一连接件4、安装座5和第二连接件7后与螺母9固定连接形成整体结构。
如图2所示，安装座5具有一定数量的周壁53，周壁53的数量不同会形成不同的周壁53外围形状，例如四边形、六边形等形状，优选四个周壁53，任两相对的周壁53的上边沿设置有外凸沿52，另两侧周壁53上设有倒扣51，倒扣51所在的周壁53上开设有避让孔57，避让孔57可设置为通孔，倒扣51沿避让孔57底边斜向上设置；安装座5还具有内环壁56，内环壁56的内圈形成安 装孔55；两个周壁53的内角处设有槽口54。结合图1，第二连接件7的外壁上抱紧设置有自锁弹簧8，自锁弹簧8与第二连接件7共中心轴线，自锁弹簧8具有弯钩81，弯钩81嵌入安装座5的槽口54内，以使自锁弹簧8与安装座5相对静止。
如图1和图3所示，第一连接件4包括花键部41、法兰部42和外齿圈部43，花键部41底部设有紧固螺钉1穿过的通孔；第二连接件7包括花键头71、圆柱部72和法兰边73；第一连接件4的花键部41穿过安装座5与第二连接件7配合连接，第二连接件7具有容纳所述花键部41的容腔，该容腔内壁设有与花键部41非圆配合的内花键，如此设置，保证第一连接件4和第二连接件7非圆配合，且能实现相对静止并同步转动；内环壁56分别与法兰边73和法兰部42贴合，具体地，法兰部42与内环壁56贴合的面上均匀设置有若干凸块，设置凸块，是为了更好地缓冲，且安装座5上安装孔55的内径大于花键部41的外径(图1中D3标注的该处外径)，并小于法兰部42及法兰边73的外径(图1中D2及D1标注的该处外径)。
实施例二
如图4～6所示，本实施例的简易安装的制动机构，包括第一连接件4、安装座5和第二连接件7，第一连接件4部分穿过安装座5，并限位于第二连接件7内，制动机构还包括紧固螺钉1、弹性件2、垫片3、橡胶垫6和螺母9，螺母9内嵌于第二连接件7中，紧固螺钉1依次穿过弹性件2、垫片3、第一连接件4、安装座5、橡胶垫6和第二连接件7后与螺母9固定连接形成整体结构，用于安装至升降立柱端部的盒体121上，其中，弹性件2可为碟簧、波簧、弹性垫片等，设置在紧固螺钉1和第一连接件4的连接处；垫片3设置于弹性件2与第一连接件4的连接处。本实施例中安装座5的结构与实施例一中的结构相 同，且第一连接件4、第二连接件7的结构也与实施例一中的结构相同。
本实施例的制动机构与盒体的安装，如图7所示，盒体121上开设有与周壁53外围形状适配的装配孔122，装配孔122的内侧壁与安装座5的周壁53配合，安装座5由倒扣51受挤压进入避让孔57，装入装配孔122中并经形变复位后与盒体121卡紧，从而盒体121固定在安装座5的倒扣51和外凸沿52之间，实现安装座5和盒体121的快速安装，与焊接、螺钉连接等方式相比，该装配过程更简便，省时省力；安装座5的外凸沿52和盒体121之间还可以增设橡胶垫6，橡胶垫6贴合在外凸沿52下表面，从而通过软连接起到减振和降噪的作用，特别是可以隔绝驱动电机11的振动向升降立柱的传递。
如图8和如图9所示，一种升降立柱的实施例，包括嵌套设置的内管组件12、中管组件18和外管组件16和驱动管19，内管组件12的一端设有安装驱动部的盒体121，盒体121内置有驱动电机11和传动机构，盒体121上设有实施例一或实施例二中简易安装的制动机构(优选实施例二中简易安装的制动机构)，传动机构与制动机构的第一连接件4相连，驱动管19与制动机构的第二连接件7非圆配合，驱动管19伸入内管组件12中，中管组件18和外管组件16内分别设有空心丝杆组件14和实心丝杆组件17。其中，外管组件16一端设有固定板161，固定板161上开设有花键孔162，实心丝杆组件17通过其一端的花键端与花键孔162配合，使得实心丝杆组件17一端固定连接至固定板161上。结合图2，第二连接件7的一端设有花键头71，驱动管19的一端设有与花键头71相配合的内花键。
内管组件12的管口安装有空心丝杆螺母13，空心丝杆螺母13安装在空心丝杆组件14外，两者通过螺纹配合。如图10和图11所示，空心丝杆螺母13上设有方槽131，内管组件12的管口处对应安装好空心丝杆螺母13的方槽131 处设有冲铆片123；空心丝杆螺母13的方槽131下方设有凹坑132。
如图12所示，空心丝杆组件14的一端设有实心丝杆螺母20，实心丝杆组件17设置在空心丝杆组件14内，且与实心丝杆螺母20螺纹配合。实心丝杆螺母20的外周面呈圆形，其外周面上设有与其配合的哈弗箱体，结合图8和图13所示，哈弗箱体由两个内侧面带半圆的块状哈弗件15拼合而成，实心丝杆螺母20外周面上开设有至少一个储油槽201，哈弗件15的半圆上开设有储油半环151，两个储油半环151拼合后形成容纳实心丝杆螺母20的环腔。哈弗箱体的外壁上设有凹槽152，中管组件18管口处对应安装好哈弗箱体的凹槽152处设有冲铆片。
具体工作原理：实施例二中简易安装的制动机构安装好并进行扭力测试，测试达标的用来安装到升降立柱驱动部的盒体121上，在制动机构向盒体121的装配孔122中持续下压时，倒扣51会产生形变，待到制动机构安装到位，倒扣51则会弹出，从而使得制动机构完成装配工作；
驱动管19从内管组件12的一端伸进去，通过其内花键与制动机构的第二连接件7的花键头71配合，通过内管组件12管口的冲铆片123，将空心丝杆螺母13固定在内管组件12管口上；同时，空心丝杆组件14伸入中管组件18内，通过其一端的实心丝杆螺母20与哈弗箱体定位，再通过冲压中管组件18上的冲铆片将定位了空心丝杆组件14的哈弗箱体限位在中管组件18管口处；且实心丝杆组件17的一端与外管组件16一端的固定板161固定，两者相对静止；然后将实心丝杆组件17通过实心丝杆螺母20安装到空心丝杆组件14中，再将空心丝杆组件14通过空心丝杆螺母13安装到驱动管19内；当需要升高升降立柱时，驱动电机11启动带动传动机构转动，使得制动机构转动，进而带动驱动管19转动，由于驱动管19内螺纹与空心丝杆组件14的内螺纹配合，使得空心 丝杆组件14相对驱动管19上升，由于空心丝杆组件14一端固定在中管组件18上，所以中管组件18跟随空心丝杆组件14上升，当空心丝杆组件14上升到最高处时，相对于驱动管19静止了，此时，实心丝杆组件17的外螺纹与空心丝杆组件14的内螺纹配合，使得实心丝杆组件17相对空心丝杆组件14上升，由于实心丝杆组件17一端与外管组件16连接，所以外管组件16跟随实心丝杆组件17上升，上升到需要的位置，通过制动机构实现自锁；当需要降低升降立柱的高度时，驱动电机11启动带动传动机构反向转动，外管组件16、中管组件18依次下降，下降到需要的位置，通过制动机构实现自锁，制动机构与驱动管19之间还设有挡圈21，用于阻止自锁弹簧8的轴向窜动，保证自锁功能不受干扰和影响。
以上说明书中描述的只是本发明的具体实施方式，各种举例说明不对本发明的实质内容构成限制，所属技术领域的普通技术人员在阅读了说明书后可以对以前所述的具体实施方式做修改或变形，而不背离发明的实质和范围。
