本申请涉及锁具技术领域，具体而言，涉及一种锁具及具有该锁具的门体。
背景技术
如图1所示，现有的三点锁由智能锁体90、上连杆92、下连杆93和导向块94等组成，智能锁体90具有三角式钢栓91，上连杆92和下连杆93分别与三角式钢栓91连接，智能锁体90的转轴与三角式钢栓91驱动连接，上连杆92和下连杆93与导向块94滑动连接。智能锁体90开启和关闭时，智能锁体90带动三角式钢栓91转动，上连杆92和下连杆93随三角式钢栓91转动的同时上下运动，以使上连杆92和下连杆93远离或插入门框的锁孔内。由于上连杆92和下连杆93的运动幅度较大，因此，上连杆92和下连杆93与导向块94之间的间隙较大，并且上连杆92和下连杆93与门框锁孔之间的间隙较大，如此导致门体和门框之间的密封性较差，无法满足门体在关门时的密封要求。

根据本申请的一个方面，提供了一种锁具，包括：锁体，锁体设置在门体上，锁体包括转轴和锁栓，锁栓具有卡接端，锁栓设置在转轴上，锁栓通过转轴转动以使卡接端卡住或远离门框；第一连杆，第一连杆具有相对设置的第一端和第二端，第一连杆的第一端与锁栓铰接；第二连杆，第二连杆具有相对设置的第一端和第二端，第二连杆的第一端和第一连杆的第二端铰接，第二连杆的第二端用于与门框配合抵接；第一导向部，第二连杆与第一导向部滑动连接，第一导向部能够使第二连杆沿直线方向移动。
进一步地，锁具还包括：第三连杆，第三连杆具有相对设置的第一端和第二端，第三连杆的第一端与锁栓铰接，且第三连杆的第一端与第一连杆的第一端分别位于转轴两侧；第四连杆，第四连杆具有相对设置的第一端和第二端，第四连杆的第一端和第三连杆的第二端转动连接，第四连杆的第二端用于与门框配合抵接；第二导向部，第二导向部与第四连杆滑动连接，第四连杆沿第二导向部做直线运动。
进一步地，第二连杆的第二端和第四连杆的第二端均设置有锁紧部，锁紧部与门框相抵接。
进一步地，锁紧部包括滚轮，滚轮可转动地设置在第二连杆的第二端和/或第四连杆的第二端，滚轮用于与门框相抵接锁紧。
进一步地，卡接端与第一连杆的第一端之间的距离等于卡接端与第三连杆的第一端的距离。
进一步地，第一导向部具有第一导向孔，第二连杆穿设在第一导向孔内，第一导向孔的截面形状与第二连杆的截面形状相适配；所述第二导向部具有第二导向孔，所述第四连杆穿设在所述第二导向孔内，所述第二导向孔的截面形状与所述第四连杆的截面形状相适配。
进一步地，第一导向部具有多个，多个第一导向部沿第二连杆的移动方向间隔排列；第二导向部具有多个，多个第二导向部沿第四连杆的移动方向间隔排列。

具体实施方式
下面将结合本申请实施例中的附图，对本申请实施例中的技术方案进行清楚、完整地描述，显然，所描述的实施例仅仅是本申请一部分实施例，而不是全部的实施例。以下对至少一个示例性实施例的描述实际上仅仅是说明性的，决不作为对本申请及其应用或使用的任何限制。基于本申请中的实施例，本领域普通技术人员在没有作出创造性劳动前提下所获得的所有其他实施例，都属于本申请保护的范围。
如图2-3所示，本申请实施例提供一种锁具，包括：锁体10、第一连杆20、第二连杆30和第一导向部40。锁体10设置在门体上，锁体10包括转轴11和锁栓12，锁栓12具有卡接端121，锁栓12设置在转轴11上，锁栓12通过转轴11转动以使卡接端121卡住或远离门框。卡接端121卡在门框上，从而将门锁住。可选的，锁体可为智能锁或机械锁。第一连杆20具有相对设置的第一端和第二端，第一连杆的第一端21与锁栓12铰接。第二连杆30具有相对设置的第一端和第二端，第二连杆的第一端31和第一连杆的第二端22铰接，第二连杆的第二端32用于与门框配合抵接。第二连杆30与第一导向部40滑动连接，第一导向部40能够使第二连杆30在第一连杆20的驱动下沿直线方向移动，第二连杆30可沿水平方向或竖直方向等方向做直线运动。一般地，第一导向部40沿竖直方向延伸，第二连杆30在第一连杆20的驱动下沿竖直方向做直线运动。第一导向部40限制了第二连杆30的运动方向，防止第二连杆30随第一连杆20转动。锁栓12和第一连杆20组成曲柄连杆结构，锁栓12绕转轴11转动时，第一连杆20随锁栓12转动的同时向靠近或远离锁栓12的方向移动，第二连杆30随第一连杆20做直线运动。可选的，锁栓12的材质可选用钢材质，这样可以保证足够的结构强度。
在本技术方案中，第一连杆20随锁栓12转动的同时向靠近或远离锁栓12的方向移动，而第二连杆30在第一连杆20传动下仅做直线运动，因此，第二连杆30的摆动幅度很小，进而可以使第二连杆30与第一导向部40之间的缝隙、第二连杆30与门框的间隙缩减到很小，使第二连杆的第二端与门框紧密抵接，进而保证了门体和门框之间的密封性。
在本实施例中，锁具还包括第三连杆50、第四连杆60和第二导向部70。第三连杆50具有相对设置的第一端和第二端，第三连杆的第一端51与锁栓12铰接，且第三连杆的第一端51与第一 连杆的第一端21分别位于转轴11两侧。第四连杆60具有相对设置的第一端和第二端，第四连杆的第一端61和第三连杆的第二端52转动连接，第四连杆的第二端62用于与门框配合抵接；第二导向部70与第四连杆60滑动连接，第四连杆60沿第二导向部70做直线运动。具体地，第二导向部70可固定在门体上。第二导向部70用于限制第四连杆60的移动方向，防止第四连杆60随第三连杆50转动。锁栓12转动时，第三连杆50随锁栓12转动的同时向靠近或远离锁栓12的方向移动，第四连杆60在第三连杆50的驱动下沿直线方向移动，第四连杆60可沿水平方向或竖直方向等方向做直线运动。一般地，第二导向部70沿竖直方向延伸，第四连杆60在第三连杆50的驱使下沿竖直方向做直线运动。由于第四连杆60做直线运动，所以第四连杆60与第二导向部70之间的缝隙可以足够小，第四连杆的第二端62与门框之间可以保持紧密抵接，在锁体处于关闭状态时，进一步保证了门体和门框之间的密封性。第二连杆的第二端32和第四连杆的第二端62在锁体的两端与门框相抵接，利用第二连杆的第二端32、锁体10、第四连杆的第二端62与门框相配合，能够使门体稳定地锁在门框上。采用上述结构，可使门体和门框之间的缝隙足够小从而保证了门体的密封性。
其中，第一连杆20和第三连杆50可以为直线型连杆、弧形连杆、弯曲式连杆等，第一连杆20、第二连杆30、第三连杆50以及第四连杆60可以设计为扁杆或者圆杆。
在本实施例中，第二连杆的第二端32和第四连杆的第二端62均设置有锁紧部，锁紧部与门框相抵接。锁紧部可为卡块或滚轮，锁紧部随第二连杆30和第四连杆60做直线运动，两个锁紧部分别与门框上部的内表面和下部的内表面相抵接，从而将门体锁紧在门框上。
具体地，锁紧部包括滚轮80，滚轮80可转动地设置在第二连杆的第二端32和/或第四连杆的第二端62，滚轮80用于与门框相抵接锁紧。滚轮80与门体之间的摩擦力小，从而使第二连杆30和第四连杆60更顺畅地移动。
在本实施例中，卡接端121与第一连杆的第一端21之间的距离等于卡接端121与第三连杆的第一端51的距离。具体地，可将锁栓12设置为T形结构，卡接端121、第一连杆的第一端21和第三连杆的第一端51分别位于锁栓12的三个端部，上述设计结构简单，方便部件之间连接。
在本实施例中，第一导向部40具有第一导向孔，第二连杆30穿设在第一导向孔内，第一导向孔的截面形状与第二连杆30的截面形状相适配；第二导向部70具有第二导向孔，所述第四连杆60穿设在所述第二导向孔内，所述第二导向孔的截面形状与所述第四连杆60的截面形状相适配。第一导向孔的延伸方向与第二连杆30的运动方向相同，第二连杆30沿第一导向孔做直线运动。第一导向孔与第二连杆30之间的缝隙很小，从而保证了第二连杆的第二端32与门框紧密抵接，进而保证了门体和门框之间的密封性。第二导向孔的延伸方向与第四连杆60的运动方向相同，第四连杆60沿第二导向孔做直线运动。第二导向孔与第四连杆60之间的缝隙很小，从而保证了第四连杆的第二端62与门框紧密抵接，进而保证了门体和门框之间的密封性。
在其它实施例中，第一导向部40和第二导向部70还可设置为滑轨，第二连杆30和第四连杆60与滑轨相适配且沿滑轨做直线运动。
在本实施例中，第一导向部40具有多个，多个第一导向部40沿第二连杆30的移动方向间隔排列；第二导向部70具有多个，多个第二导向部70沿第四连杆60的移动方向间隔排列。将第一导向部40和第二导向部70设置为多个，可进一步保证第二连杆30和第四连杆60做直线运动，且使第二连杆30和第四连杆60与门框抵接时不会歪斜，从而进一步保证了锁紧部紧密地与门框抵接。
在本实施例中，第二连杆30的轴线与第四连杆60的轴线相重合。即，第二连杆30与第四连杆60在同一条直线上移动，如此设置，可使锁具和门框之间的作用力均衡，以保证整体结构的稳定性。
在本实施例中，锁体10还包括把手13，把手13与转轴11驱动连接，把手13通过转轴11驱动锁栓12转动。把手13带动转轴11转动，进而带动锁栓12转动，锁栓12转动时，卡接端121卡住或远离门框，第一连杆20和第三连杆50转动，第二连杆30和第四连杆60随之做直线运动，锁紧部抵住或远离门框，从而实现锁具的关闭或开启。设置把手13方便打开或关闭锁具。
本申请还提供一种门体，包括上述技术方案描述的锁具。采用上述技术方案描述的锁具，可使门体和门框之间密封性更好。
在本技术方案中，采用多连杆的结构，可以将两端的连杆与门框紧密抵接，进而保证了门体和门框之间的密封性；在第二连杆的第二端32和第四连杆的第二端62上设置滚轮80，能够使第二连杆30和第四连杆60顺畅地移动。通过本申请提供的技术方案，其结构简单，便于生产和拆装，其能够满足门体与门框之间密封性的要求。
