Description
本发明属于船舶制造技术领域，尤其涉及一种埋入式人孔盖。
目前船舶上通常在通道内设置人孔，此类人孔处大多采用埋入式人孔盖进行封闭，以便于船员行走。如果通道内没有装饰要求，那么通道内大多会仅涂设油漆，如果通道内有装饰要求，那么会在此通道内敷设甲板敷料及PVC地板胶，地板胶敷设在整个通道内，将会粘接在通道的板面和埋入式人孔盖上。现有技术存在以下缺陷：1、若要打开埋入式人孔盖，需要先将整块PVC地板胶翻开，才能露出地板胶下面的人孔盖，操作极为不便；2、PVC地板胶翻开后，破坏了原来的粘结层，人孔盖使用完毕盖回后，必须要用胶水重新粘回去，增加了操作工序和操作难度；3、PVC地板胶反复粘接、撕开，容易起泡变形，破坏其美观度，增加了保养难度。
发明内容
本发明的目的在于：提供一种埋入式人孔盖，其结构简单，启闭方便，不仅能保证与地板胶之间的有效连接，保证通道的美观性，还能降低施工难度。
为达上述目的，本发明采用以下技术方案：
提供一种埋入式人孔盖，包括固定在甲板的人孔内的安装座和可拆卸设置在所述安装座上的盖本体，所述盖本体上设置有遮盖所述甲板和所述盖本体之间的间隙的压板组件，所述压板组件包括环形设置的压板和用于将所述压板可
拆卸固定在所述甲板上的紧固件，当所述压板与所述盖本体固定时，所述压板的宽度方向的一侧与设置在所述盖本体上的第一地板胶抵接，所述压板的宽度方向的另一侧与设置在所述甲板上的第二地板胶抵接，以将所述第一地板胶压紧在所述盖本体上。
作为埋入式人孔盖的一种优选方案，所述压板包括压板本体，所述压板本体的宽度方向两侧分别设置有第一抵接板和第二抵接板，所述第一抵接板与所述第二抵接板均设置在所述压板本体靠近所述盖本体的一侧面上，并且所述第一抵接板与所述第二抵接板均朝向远离所述压板本体的中心的一侧倾斜设置。
作为埋入式人孔盖的一种优选方案，所述第一抵接板和所述第二抵接板与水平面的夹角均为锐角。
作为埋入式人孔盖的一种优选方案，所述紧固件包括固定板和紧固螺钉，所述压板本体上开设第一固定孔，所述紧固件相对于所述甲板的位置固定，所述固定板上开设有第二固定孔，所述第二固定孔为螺纹孔，所述紧固螺钉贯穿所述第一固定孔与所述第二固定孔螺纹旋接。
作为埋入式人孔盖的一种优选方案，所述第一固定孔为沉孔，所述紧固螺钉的螺帽部分全部位于所述第一固定孔内。
作为埋入式人孔盖的一种优选方案，所述固定板与所述安装座固定连接；或，所述固定板通过连接件与所述甲板连接。
作为埋入式人孔盖的一种优选方案，所述固定板与所述甲板平行且间隔。
作为埋入式人孔盖的一种优选方案，所述压板上环形等间距设置有多个所述第一固定孔，所述甲板上设置有数量和位置与所述第一固定孔对应的紧固件。
作为埋入式人孔盖的一种优选方案，所述第一地板胶远离所述盖本体的一侧面与所述第二地板胶远离所述甲板的一侧面平齐。
作为埋入式人孔盖的一种优选方案，所述安装座为环形结构，所述安装座的外壁与所述甲板的人孔内壁焊接，所述安装座与所述第二地板胶之间具有供所述紧固件通过的空间。
本发明的有益效果为：通过设置压板，不仅可以遮盖住甲板与盖本体之间的间隙，还可以利用此压板将盖本体上的第一地板胶压紧在此盖本体上，这样可以省去在盖本体和第一地板胶上刷胶水的工序，即第一地板胶与盖本体之间的连接不需要通过胶水粘接，只需要压板压紧即可，进一步避免因粘结层破坏而重新涂抹胶水粘接地板胶，减少了施工工序，提高了工作效率，同时还很好的保护了甲板上的第二地板胶，防止因反复掀起、粘接对此地板胶造成破坏而最终需要重新更换新的地板胶的情况发生，进而降低了成本。对比现有技术，本方案的埋入式人孔盖具有结构简单、启闭方便的优点，不仅能保证与地板胶之间的有效连接，保证通道的美观性，还能降低施工难度。

为使本发明解决的技术问题、采用的技术方案和达到的技术效果更加清楚，下面将结合附图对本发明实施例的技术方案作进一步的详细描述，显然，所描述的实施例仅仅是本发明一部分实施例，而不是全部的实施例。基于本发明中的实施例，本领域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，都属于本发明保护的范围。
在本发明的描述中，除非另有明确的规定和限定，术语“相连”、“连接”、“固定”应做广义理解，例如，可以是固定连接，也可以是可拆卸连接，或成一体；可以是机械连接，也可以是电连接；可以是直接相连，也可以通过中间媒介间接相连，可以是两个元件内部的连通或两个元件的相互作用关系。对于本领域的普通技术人员而言，可以具体情况理解上述术语在本发明中的具体含义。
如图1至3所示，于本实施例中，本发明的埋入式人孔盖，包括固定在甲板1的人孔内的安装座2和可拆卸设置在安装座2上的盖本体3，盖本体3上设置有遮盖甲板1和盖本体3之间的间隙的压板组件，压板组件包括环形设置的压板4和用于将压板4可拆卸固定在甲板1上的紧固件，当压板4与盖本体3固定时，压板4的宽度方向的一侧与设置在盖本体3上的第一地板胶5抵接，压板4的宽度方向的另一侧与设置在甲板1上的第二地板胶6抵接，以将第一地板胶5压紧在盖本体3上。通过设置压板4，不仅可以遮盖住甲板1与盖本体3之间的间隙，还可以利用此压板4将盖本体3上的第一地板胶5压紧在此盖本体3上，这样可以省去在盖本体3和第一地板胶5上刷胶水的工序，即第一地板胶5与盖本体3之间的连接不需要通过胶水粘接，只需要压板4压紧即可，进一步避免因粘结层破坏而重新涂抹胶水粘接地板胶，减少了施工工序，提高
了工作效率，同时还很好的保护了甲板1上的第二地板胶6，防止因反复掀起、粘接对此地板胶造成破坏而最终需要重新更换新的地板胶的情况发生，进而降低了成本。对比现有技术，本方案的埋入式人孔盖具有结构简单、启闭方便的优点，不仅能保证与地板胶之间的有效连接，保证通道的美观性，还能降低施工难度。
在本发明的一个优选的实施例中，压板4包括压板本体41，压板本体41的宽度方向两侧分别设置有第一抵接板42和第二抵接板43，第一抵接板42与第二抵接板43均设置在压板本体41靠近盖本体3的一侧面上，并且第一抵接板42与第二抵接板43均朝向远离压板本体41的中心的一侧倾斜设置。位于压板本体41同侧设置的两个抵接板均呈倾斜设置，且均沿远离压板本体41的中心的一侧倾斜，可以使压板本体41与甲板1或人孔盖上的地板胶之间均具有一定的距离，此距离可以有效防止压板4抵接在地板胶上的侧边发生翘边的情况，且倾斜结构的抵接板可以在紧固件对压板4施加紧固力时更加贴合盖本体3或者甲板1上的地板胶，有效防止灰尘堆积在压板4与地板胶的连接处，也可以防止盖本体3处的地板胶固定失效，另外此设计可以在紧固件的作用力越大的情况下，抵接在地板胶处的作用力也越大，且越不容易发生翘边的情况。
如果采用的压板4是平板结构，那么在紧固件将压板4固定在盖本体3上时，作用力越大，越容易出现翘边的情况，翘边具体是指：施加在压板4中部的作用力较大，使得压板4产生中部下凹，两边上翘的变形，翘边情况的发生会出现以下两个问题：第一、使压板4与盖本体3上的地板胶之间的抵接作用力失效，盖本体3上的地板胶由于未与盖本体3粘接，在压板4抵接作用力失效的情况下，地板胶长期使用后会脱离压板4和盖本体3，影响使用；第二、翘边后，压板4边缘部分会与地板胶之间产生缝隙，此缝隙会收集灰尘、固体颗
粒物等杂质。
在本实施例中，第一抵接板42与第一地板胶5抵接，第二抵接板43与第二地板胶6抵接。
优选的，压板本体41靠近甲板1的一侧与第一地板胶5远离盖本体3的一侧面之间的间距为3～5mm。通过将压板本体41与第一地板胶5之间的距离设置为上述距离，一方面是为了保证此压板4在被紧固件固定时具有一定的调节空间，另一方面是为了防止压板4太凸出于通道的表面，对使用者行走造成障碍。
在本实施例中，第一抵接板42和第二抵接板43与水平面的夹角均为锐角。通过将两个抵接板与水平面之间的夹角设置为锐角，可以在保证压板4较小的凸出高度的同时具有较宽的与各个地板胶的压接面。
在本发明的另一个优选的实施例中，紧固件包括固定板7和紧固螺钉8，压板本体41上开设第一固定孔44，紧固件相对于甲板1的位置固定，固定板7上开设有第二固定孔，第二固定孔为螺纹孔，紧固螺钉8贯穿第一固定孔44与第二固定孔螺纹旋接。通过采用紧固螺钉8将压板4固定在固定板7上，可以便于后期人孔盖的启闭操作，降低操作难度，即拧开紧固螺钉8移开压板4和第一地板胶5就能开启人孔盖。
在本实施例中，第一固定孔44为沉孔，紧固螺钉8的螺帽部分全部位于第一固定孔44内。通过将第一固定孔44设置为沉孔，可以将紧固螺钉8整个拧入到压板4内，避免紧固螺钉8突出到压板4外影响使用者使用。
进一步的，固定板7与安装座2固定连接；或，固定板7通过连接件与甲板1连接。为了使固定板7与甲板1之间的相对位置固定，可以选择将固定板7直接与安装座2连接或者固定板7通过连接件与甲板1连接。
具体的，固定板7与甲板1平行且间隔。通过将固定板7与甲板1平行设
置，使得固定板7上的第二固定孔的轴线垂直于甲板1，进而更加便于将紧固螺钉8拧紧在固定板7上。
在本发明的又一个优选的实施例中，压板4上环形等间距设置有多个第一固定孔44，甲板1上设置有数量和位置与第一固定孔44对应的紧固件。
进一步的，在甲板1靠近压板4一侧设置有多个与第一固定孔44位置对应的固定板7；或，固定板7呈环形，固定板7上开设有数量和位置与第一固定孔44相对应的第二固定孔。
在本发明的一个实施例中，第一地板胶5远离盖本体3的一侧面与第二地板胶6远离甲板1的一侧面平齐。在其他实施例中，第一地板胶5的上表面和第二地板胶6的上表面还可以设置为非平齐结构，即第一地板胶5的上表面的高度不等于第二地板胶6的上表面的高度。
由于本发明的压板4采用的是压板本体41的同侧设置两个朝向远离压板本体41中心的一侧倾斜的抵接板，使得第一地板胶5的上表面即使不与第二地板胶6的上表面平齐也可以在此压板4的压紧作用下保持与压板4呈良好的抵接状态。
在本发明的另一个实施例中，安装座2为环形结构，安装座2的外壁与甲板1的人孔内壁焊接，安装座2与第二地板胶6之间具有供紧固件通过的空间。优选的，第二地板胶6与甲板1之间还设置有敷料9。
进一步的，固定板7呈环形，其内孔的尺寸大于安装座2的内孔的尺寸并小于安装座2的外尺寸，固定板7的内孔的壁面与安装座2焊接。
在本发明的一个具体的实施例中，如图1至3，此埋入式人孔盖包括安装座2和盖本体3，安装座2固定在甲板1的人孔内并部分凸出于甲板1的上表面，盖本体3可转动设置在此安装座2内，盖本体3的上表面与安装座2的上端面
