一种快速安装的桌架和升降平台 【技术领域】
本发明涉及一种快速安装的桌架和升降平台，属于家具设备领域。
【背景技术】
升降平台，尤其是电动升降平台，比如升降桌，目前在办公、家居领域越来越受欢迎，由于升降平台占用空间较大，不方便运输，故目前升降平台的生产厂家在出厂时通常是没有组装好的，消费者购买后自行组装或由厂家上门进行组装，故如何实现快速组装或者方便组装，是目前升降平台或电动升降平台亟待解决的问题。
目前的升降平台，其通常包括台面和桌架，而桌架则包括横梁、升降立柱，通常后期组装主要在于横梁与升降立柱之间，目前较为常见是采用螺钉固定，采用螺钉固定的方式需要借助工具，同时要拧动多颗螺钉，还要保证对孔，使得组装步骤较为繁琐，也较为费力。
【发明内容】
本发明所要解决的技术问题在于克服现有技术的不足而提供一种快速安装的桌架，使得桌架的组装更为快速、方便。
解决上述技术问题，本发明采用如下技术方案：

第二，本发明中升降立柱和横梁之间的固定方式是通过锁销与锁定件实现，与其他部件关系度不大，故只要保证锁销和锁定件的刚性或硬度即可，对于升降立柱表面硬度等要求并不高，可以采用成本相对较低的材料来实现；
第三，操作活动式的锁定件，比如旋转锁定件或者滑动锁定件，其操作便利性远比拧动多颗螺钉要快捷、省力；
第四，简化组装步骤，整个组装过程，只需要将锁销插入第一插入段并滑动至第一锁定段，该步骤一步即可完成，然后操作锁定件进行限位，故升降立柱与横梁之间的连接，实际上只需要两个步骤即可完成。
作为优选，所述横梁沿横向方向间隔设置有至少两个锁定槽；和/或，所述横梁上设有容置腔，所述升降立柱部分安装在容置腔内，所述容置腔沿纵向方向的两个相对壁上分别设置有所述锁定槽。

【具体实施方式】
下面结合本发明实施例的附图对本发明实施例的技术方案进行解释和说明，但下述实施例仅为本发明的优选实施例，并非全部。基于实施方式中的实施例，本领域技术人员在没有做出创造性劳动的前提下所获得其他实施例，都属于本发明的保护范围。
在下文描述中，出现诸如术语“内”、“外”、“上”、“下”、“左”、“右”等指示方位或者位置关系，仅是为了方便描述实施例和简化描述，而不是指示或暗示所指的装置或者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。
实施例一
如图1至图5所示，本实施例公开的为一种快速安装的桌架，包括横梁1，为了方便描述，本实施例中横梁1的长度方向定义为横向方向，宽度方向定义为纵向方向，所述横梁1上安装有升降立柱2，所述横梁1上设有锁定槽11，所述锁定槽11包括相互连通的第一插入段111和第一锁定段112，所述升降立柱2上设有锁销21，所述横梁1上活动安装有锁定件3，锁定件3包括解锁状态和锁定状态，解锁状态下，所述锁销21从第一插入段111装入并进入第一锁定段112，锁定状态下，所述锁定件3与锁销卡接，并将锁销21限位在第一锁定段112内，以使所述升降立柱2与横梁1连接固定。需要说明的是，这里所指的卡接，不仅仅局限于利用卡槽限位卡接，也可以是锁销21与锁定件3相互抵触限位实现卡接。
在组装时，可以将升降立柱2上的锁销21对准插入第一插入段111，并将锁销21从第一插入段111移动到第一锁定段112内，然后利用活动的锁定件3，与锁销21实现卡接，从而将锁销21限位在第一锁定段112内，从而间接使得升降立柱2与横梁1之间相对锁定，即完成了升降立柱2与横梁1之间的固定连接。 这种连接方式具备的优点：
首先，不需要借助工具，只需要操作原本就活动安装在横梁1上的锁定件3就可以；
其次，操作活动式的锁定件3，比如旋转锁定件3或者滑动锁定件3，其操作便利性远比拧动多颗螺钉要快捷、省力；
最后，简化组装步骤，整个组装过程，只需要将锁销21插入第一插入段111并滑动至第一锁定段112，该步骤一步即可完成，然后操作锁定件3进行限位，故升降立柱2与横梁1之间的连接，实际上只需要两个步骤即可完成。
具体的优选结构：
本实施例中锁销21优选是圆柱销，为了防止圆柱销在第一锁定段112内发生转动，所述横梁1沿横向方向间隔设置有至少两个锁定槽11，而升降立柱2上也相应设置有数量、位置相对应的锁销21，本实施例中横梁1沿横向间隔设置有两个锁定槽11，当横向方向两个锁销21进入第一锁定段112后，升降立柱2就无法实现转动，定位效果更好。
本实施例中的锁销21优选是固定在升降立柱2上的螺钉，考虑到固定时，均是依靠锁销21与锁定件3相互卡接来实现，所以锁销21和锁定键件3如果长期使用可能会存在一定磨损，故锁销21设置成可拆卸式或可更换式的，另外，本实施例中升降立柱2和横梁1之间的固定方式是通过锁销21与锁定件3实现，与其他部件关系度不大，故只要保证锁销21和锁定件3的刚性或硬度即可，对于升降立柱2表面硬度等要求并不高，可以采用成本相对较低的材料来实现。
所述横梁1上设有容置腔，所述升降立柱2部分安装在容置腔内，本实施例中为了让升降立柱2与横梁1之间的连接关系更稳固，所述容置腔沿纵向方向的两个相对壁上分别设置有所述锁定槽11。也就是说，本实施例中的横梁1其实设置有四个锁定槽11。
本实施例中所述锁销21在第一插入段111的行走轨迹和在第一锁定段112内的行走轨迹相交成一角度，相当于第一插入段111的走向与第一锁定段112的走向不在同一直线上，本实施例中第一锁定段112的走向与横梁1的长度方向 相同，而第一插入段111的走向与横梁1的长度方向基本垂直，故本实施例中的锁定槽11大致呈L形状，本实施例中的升降立柱2优选包括壳体22和立柱本体23，锁销21则设置在壳体22的侧壁上。
为了方便组装，同时所述第一插入段111贯通至横梁1的底部，由于横梁1的顶部是直接安装台面的，将第一插入段111贯通至横梁1的底部，即便在台面已经安装好后，也可以对将升降立柱2从横梁1底部插入，增加了组装的自由度。
需要说明的是，本领域技术人员也容易知晓，上述锁定槽11的形状结构只是优选方案，在其他实施方式中，第一插入段111不局限于贯通至横梁1的底部，也可以贯通至横梁1的顶部，或者贯通至横梁1的端部，均是可以的，另外，在其他实施方式中，锁定槽11的形状也不局限于L形，也可以是V形、C形、S形等等、甚至第一插入段111和第一锁定段112还可以是同一直线，这些实施方式均落入本发明的保护范围。
为了让台面安装到桌架上后稳定性更好，本实施例中的桌架还包括安装在横梁1端部的侧固定板4，侧固定板4优选有两块，分别安装在横梁1的两个端部，本实施例中为了方便组装侧固定板4，所述侧固定板4朝向横梁1延伸有延伸板41，所述延伸板41上设有限位槽42，所述限位槽42包括与第一插入段111匹配的第二插入段421、和与第一锁定段112匹配的第二锁定段422，所述锁销21进入锁定槽11的同时也进入限位槽42。
这里所指的第一插入段111和第二插入段421匹配、第一锁定段112与第二锁定段422匹配，是指当侧固定板4与横梁1初步定位完成后，第一插入段111的形状、位置与第二插入段421对应，第一锁定段112与第二锁定段422的形状、位置对应，需要说明的是，本领域技术人员也应知晓，这里所指的形状对应并不局限于形状完全相同，只要锁销21由第一插入段111进入第一锁定段112的同时，也相应从第二插入段421进入第二锁定段422，形状上可以允许存在一定差异。
将侧固定板4如此设置后，当侧固定板4与横梁1完成初步定位后，只需要一次操作锁定件3，就可以同时完成对升降立柱2、侧固定板4的锁定连接，即一个锁定步骤完成对两个零部件的组装锁定，组装更加方便。需要说明的是， 在其他实施方式中，并不局限于在侧固定板4上设置限位槽42，侧固定板4可以是单独通过紧固螺钉等方式单独与横梁1固定，这类实施方式均落入本发明的保护范围。
为了防止延伸板41与横梁1之间存在纵向方向位移，以避免锁销21沿纵向方向从第二锁定段422中脱离，所述横梁1包括两根沿纵向方向间隔设置的中空管10，两根中空管10之间的纵向空间形成所述容置腔，所述锁定槽11设置在中空管10壁上，所述延伸板41插入在所述中空管10的内部空腔101中，内部空腔101的两个纵向相对的内壁可以对延伸板41纵向限位，从而防止延伸板41纵向移动，作为优选，本实施例的延伸板41为U形板，其纵向长度基本与中空管10的内部空腔101的纵向长度相同。
本实施例中还对锁定件3进行了优化设计，所述锁定件3转动安装在横梁1上，所述锁定件3上设有卡槽33，锁定件3在锁定状态下，所述锁销21卡在所述卡槽33内。利用转动的方式来实现解锁和锁定，操作更为方便。
具体如图3至图5所示，所述锁定件3包括相互铰接的第一连杆31和第二连杆32，第一连杆31铰接在横梁1上，所述卡槽33位于第二连杆32上，锁定件3从解锁状态到锁定状态过程中，所述第一连杆31相对于横梁1的转动方向，与第二连杆32相对于第一连杆31的转动方向相反。如图3至图4，当从解锁状态到锁定状态时，第二连杆32相对于第一连杆31的转动方向是顺时针转动，而第一连杆31相对于横梁1的转动方向，是逆时针转动方向，这样的连杆机构，更加容易形成一死点，以避免轻易被解锁。
可参见图4，所述第一连杆31与第二连杆32的铰接点为第一中心点301，第一连杆31与横梁1的铰接点为第二中心点302，锁销21的中心为第三中心点303，在锁定状态下，所述第一中心点301、第二中心点302、第三中心点303不在同一直线上，如此第一连杆31、第二连杆32在锁定状态下，形成一个死点。
为了方便消费者操作锁定件3，所述锁定件3上还设有锁定或解锁用的操作手柄34。本实施例中的操作手柄34是第二连杆32上折弯形成的拨片，作为优选，锁定件3在锁定状态下，该拨片刚好贴合在横梁1的底面，这样锁定件3在锁定状态下，更加稳定，晃动度更小。本实施例中锁定件3优选有两个，两个锁定件3分别转动安装在横梁1纵向方向的两个相对壁上，每个锁定件3上均有操作手柄34。
实施例二
如图6至图7所示，本实施例与实施例一的区别在于，本实施例中对卡槽33进行了改进优化，本实施例中的卡槽33与实施例一一样均为开口槽，但是本实施例中在开口槽的开口位置设置一个凸起331，在锁定件3锁定状态时，该凸起331的凸起方向大致朝向第一锁定段112的滑出方向，锁定件3从锁定状态到解锁状态的过程中，具体而言，所述第二连杆32从锁定状态朝解锁状态转动过程中，所述凸起331与所述锁销21相抵并对锁销21产生解锁方向的推力，这里所指的解锁方向，是锁销21从第一锁定段112内的滑出方向。
由于第一锁定段112与锁销21之间的匹配是比较紧凑的，两者之间的间隙较小，故锁销21滑入第一锁定段112内后，有几率会卡死在第一锁定段112内，导致即便是锁定件3已经解锁，但是锁销21仍在第一锁定段112内无法滑出，而本实施例设计这一凸起331后，使得第二连杆32在朝解锁方向转动时，凸起331会顶住锁销21，并且第二连杆22在转动过程中，凸起331会对锁销21产生推力，从而实现对锁销21产生松动效果，以方便用户将锁销21从第一锁定段112内推出。
另外，本实施例与实施例1的区别，还包括：本实施例中的所述锁定件3的数量包括两个，两个锁定件3分别位于横梁1纵向方向的两个相对壁上，所述两个锁定件3之间连接有连接板35，连接板35可以将两个锁定件3连接起来，加强稳定性，同时连接板35可以作为操作手柄来使用，拨动连接板35可以同时操作两个锁定件3同步转动，即两个锁定件3、连接板35是一体式的。
需要说明的是，实施例一中的两个分离式的锁定件结构，也可以替换成本实施例中的一体式的锁定件结构，本实施例中的一体式的锁定件结构，也可以替换成实施例一中的分离式的锁定件，这类实施方式变化均落入本发明的保护范围内。
实施例三
本实施例与实施例一的区别在于，锁定件并非是转动安装在横梁上，锁定件可以是滑动安装在横梁上，当锁销进入到第一锁定段内后，消费者可以滑动锁定件，锁定件与锁销外壁相互抵触，以实现卡接，从而使得锁销限位在第一锁定段内，至于锁定件如何保持在锁定状态，可以在横梁上设置一个扣孔，锁 定件上设置一个卡扣，当锁定件滑动到锁定位置时，卡扣嵌入扣孔内，当然还可以是其他固定方式，这里不再穷举。
实施例四
本实施例为一种升降平台，包括台面和桌架，其中所述桌架采用实施例一或实施例二或实施例三或与其相等同的实施方式的桌架。
以上所述，仅为本发明的具体实施方式，但本发明的保护范围并不局限于此，熟悉该本领域的技术人员应该明白本发明包括但不限于附图和上面具体实施方式中描述的内容。任何不偏离本发明的功能和结构原理的修改都将包括在权利要求书的范围中。
