Description

一种锁扣式拼装组合式托盘 技术领域
本发明涉及货物运输和仓储的托盘，特别涉及一种拼装组合式的托盘。
背景技术
在货物的运输和仓储中，为了能用叉车搬运，托盘是必不可少的用具。
现有技术中，最常见的托盘从材质上分，有木质、塑料质以及铝合金质。木质托盘，最早出现，长期使用后易变形，甚至腐烂。塑料托盘，克服了木质易变形腐烂的缺点，但是其在长期使用后其表面也易藏菌，卫生性仍不佳。
铝合金托盘是近年来才出现的，其卫生性好，能用于运输食品等，但现国内的铝合金托盘都为固定式结构，从结构上看，它包括多根支撑梁，这些支撑梁在水平面上并列相距设置，在这些支撑梁的顶面上铺设多块栈板，栈板的长度方向与支撑梁的长度方向相垂直，并且，栈板与支撑梁间是通过焊接或铆接的方式固定连接，是无法重复安装和拆卸的。这样的托盘在不用时，其运输和存储都只能整体摆放和堆彻，占用空间大，运输和仓储成本均较高。
近年来，有尝试设计可拆卸组装的铝合金托盘，具代表性的结构，可参见授权公告号为CN204056575U的实用新型专利。该专利公开的托盘包括栈板和支撑梁，所述支撑梁采用中空的金属型材，各支撑梁顶面上沿其长度方向开设有嵌槽，该嵌槽的两槽壁上均向槽内设有卡边；所述各栈板底面上对应各支撑梁顶面上的嵌槽向下凸设有嵌入块，嵌入块沿嵌槽的长度方向嵌入对应嵌槽内，嵌入块在上下竖直方向上与卡边卡挡配合；并且，所述各支撑梁对应每一栈板的嵌入块设置有定位杆，该定位杆沿支撑梁宽度方向穿置于支撑梁上，而每一栈板的嵌入块上对应于定位杆开设有锁孔，定位杆穿过对应的嵌入块上的锁孔，将栈板锁定。该专利公开的方案具有栈板与支撑梁的连接可靠性高的优点，但是，就因为拆卸栈板只能是从嵌槽中平移出，若位于中部的某块栈板损坏要更换时，需要从外侧起一块块的栈板都平移卸下，才能更换到中部的栈板，费时费力。
发明内容
本发明目的是提供一种锁扣式拼装组合式托盘，在保留栈板与支撑梁的连接可靠性高的前提下，使栈板可从垂直方向安装于支撑梁上，解决了更换中部的栈板麻烦的问题。
为达到上述目的，本发明采用的技术方案是：一种锁扣式拼装组合式托盘，包括多根并列设置的支撑梁以及铺设于支撑梁顶面上的多块栈板，所述栈板的长度方向与支撑梁的长度方向相垂直；支撑梁顶面上沿其长度方向开设有嵌槽，各该嵌槽的至少一槽壁向槽内设有卡挡部；所述各栈板底面上对应各支撑梁顶面上的嵌槽设有嵌入块，所述各支撑梁 对应每一栈板的嵌入块设置有定位杆，该定位杆沿支撑梁宽度方向穿置于支撑梁，且穿过对应的嵌入块将栈板在沿嵌槽的长度方向上锁定；
所述嵌入块包括一主体，该主体在嵌槽的宽度方向的至少一侧侧部上设有一锁钩，该锁钩上端与主体转动配合形成支点，而下端外侧设有钩部与嵌槽的卡挡部卡挡配合；所述钩部和卡挡部的卡档配合的接触点上，至少一者上设有脱钩斜面；
所述嵌槽的槽底上对应于锁钩底部内侧设有一暂定位斜面，在所述定位杆未穿置的状态下，当嵌入块嵌入嵌槽后，锁钩的内侧与暂定位斜面滑动配合，使锁钩向外转动，其钩部与嵌槽的卡挡部卡挡配合，以此构成对嵌入块的暂定位结构；而当受到外力作用，钩部和卡挡部以脱钩斜面发生滑动配合，使锁钩的钩部脱出卡挡部，以使嵌入块能够在上下方向上脱出嵌槽；
而当所述定位杆穿置的状态下，所述定位杆将嵌入块在上下方向定位，使锁钩保持在其钩部与嵌槽的卡挡部卡挡配合的状态，即构成真正锁定状态。
上述方案中，所述嵌槽的两槽壁上均向槽内对称设有卡挡部，所述主体在嵌槽的宽度方向的两侧侧部上均对称设有锁钩，所述嵌槽的槽底上对应于两锁钩内侧均各设一暂定位斜面。
上述方案中，所述主体和锁钩上均设有通孔供所述定位杆穿过。
上述方案中，所述主体的底面中部与嵌槽的槽底面两者间，一者上设有卡槽，另一者上设有卡筋，卡槽与卡筋卡嵌配合。
上述方案中，所述主体上设有沿嵌槽的长度方向的截面为大于半圆的圆缺形的凹槽，所述锁钩上对应设有凸出部，该凸出部沿嵌槽的长度方向嵌入凹槽，凸出部与凹槽配合构成所述支点。
上述方案中，所述主体上设有沿嵌槽的长度方向的截面为小于或等于半圆的圆缺形的凹槽，所述锁钩上对应设有凸出部，该凸出部沿嵌槽宽度方向嵌入凹槽，凸出部与凹槽配合构成所述支点。

与现有技术对比，本发明具有以下优点：
1、由于本发明的特殊设计，在将定位杆卸掉后，栈板可在上下方向上嵌入或脱出嵌槽，当某块栈板损坏时，坏哪块就直接卸下和安装那一块即可，方便性大幅提高；
2、由于本发明的特殊设计，在定位杆穿置的装配状态下，嵌入块上的锁钩被锁定不能动，使钩部与卡挡部保持卡挡状态，此时嵌入块与嵌槽的配合形式等同于现有技术，嵌入块在 上下方向上是不能脱出嵌槽的，故而本发明保留了现有技术的栈板与支撑梁连接可靠的优点。

具体实施方式
下面结合附图及实施例对本发明作进一步描述：
实施例：一种锁扣式拼装组合式托盘，如图1-图9所示：
参见图1所示，所述托盘包括多根并列设置的支撑梁1以及铺设于支撑梁1顶面上的多块栈板2，所述栈板2的长度方向与支撑梁1的长度方向相垂直；各支撑梁的1的底面上再连接有底连接板4。
参见图1-2所示，所述支撑梁1顶面上沿其长度方向开设有嵌槽11，各该嵌槽11的两槽壁上均向槽内设有卡挡部111。所述各栈板2底面上对应各支撑梁1顶面上的嵌槽11设有嵌入块21，所述各支撑梁1对应每一栈板2的嵌入块21设置有定位杆3，该定位杆3沿支撑梁1宽度方向穿置于支撑梁1，且穿过对应的嵌入块21将栈板2在沿嵌槽11的长度方向上锁定。
参见图3-图9所示，所述嵌入块21包括一主体211，该主体211在嵌槽11的宽度方向的两侧侧部上各对称设有一锁钩212，该锁钩212上端与主体211转动配合形成支点，而下端外侧设有钩部2121与嵌槽11的卡挡部111卡挡配合；所述钩部2121和卡挡部111的卡档配合的接触点上，至少一者上设有脱钩斜面，具体如图3-图9所示，是钩部2121上设有脱钩斜面21211，而卡挡部111上也对应设与脱钩斜面21211配合的脱钩斜面1111。
具体，卡挡部111的上沿还设有与锁钩212的钩部2121的外侧底沿配合的配合斜面1112。
参见图3-图9所示，所述嵌槽11的槽底上对应于两锁钩212底部内侧各对称设有一暂定位斜面113，在所述定位杆3未穿置的状态下，当嵌入块21嵌入嵌槽11后，先是锁钩212的钩部2121触碰配合斜面1112以此越过卡挡部111，然后锁钩212的内侧与暂定位斜面113滑动配合，使锁钩212向外转动，其钩部2121与嵌槽11的卡挡部111卡挡配合，以此构成对嵌入块21的暂定位结构。而当受到外力作用，钩部2121和卡挡部111以脱钩斜面发生滑动配合，使锁钩212的钩部2121脱出卡挡部111，以使嵌入块21能够在上下方向上脱出嵌槽11。
而当所述定位杆3穿置的状态下，所述定位杆3将嵌入块21在上下方向定位，使锁钩212保持在其钩部2121与嵌槽11的卡挡部111卡挡配合的状态，即构成真正锁定状态，如图9所示。
所述主体211的底面中部与嵌槽11的槽底面两者间，一者上设有卡槽112，另一者上设有卡筋2111，卡槽112与卡筋2111卡嵌配合。
具体如图3-9所示，所述嵌槽11的槽底面上设有两个斜向壁面，这两斜向壁面均向内倾斜，构成八字形，这两斜向壁面之间的空间即构成所述卡槽112，而所述斜向壁面的外侧面即作为所述暂定位斜面113。所述卡筋2111是由主体211底面中部上向下设置的两个竖向壁构成，且竖向壁底端向内侧折弯形成与卡槽112的槽口配合的导向面。如此设计，有以下作用：一是在嵌入块21沿上下方向嵌入嵌槽11的过程中，卡槽112与卡筋2111的配合起到了导向的作用，以免嵌入块21左右偏移；二是在嵌入块21嵌入嵌槽11到位后，经卡槽112与卡筋2111卡嵌配合，主体211与嵌槽11的槽底连接成一体，以免穿入定位杆3时嵌入块2发生左右偏移，同时也提高了支撑强度。
参见图3-图9所示，所述主体211上设有沿嵌槽11的长度方向的截面为大于半圆的圆缺形的凹槽2112，所述锁钩212上对应设有凸出部2123，该凸出部2123沿嵌槽11的长度方向嵌入凹槽2112，凸出部2123与凹槽2112配合构成所述支点。如此设计，使锁钩212的凸出部2123仅能从嵌槽11的长度方向嵌入凹槽2112，使装配后，嵌入块21能自成一个整体，不会解架。
最佳的，所述主体211上在凹槽2112的外侧还设有一向下的阻挡面，该阻挡面与锁钩212的顶面配合将锁钩212向外转动的极限位置限制为上下垂直状态。
参见图3-图9所示，所述主体211和锁钩212上均设有通孔供所述定位杆3穿过。较佳的，所述锁钩212内侧还设有一面朝上的台阶定位面2122，当所述定位杆3穿置的状态下，定位杆3与台阶定位面2122相抵配合，将锁钩212保持在其钩部2121与嵌槽11的 卡挡部111卡挡配合的状态。
本实施例使用状态如下：
参见图4所示，所述嵌入块21从上向下嵌入嵌槽11，图5是嵌入一半的状态，当嵌入至图6的状态时，所述锁钩212的钩部2121的底沿外侧与配合斜面1112相抵接触，使锁钩212向内转让开卡档部111，然后当达到图7的状态下，所述锁钩212的底部内暂定位斜面113相抵滑动配合，使锁钩向外侧转动，直至锁钩212的钩部2121与嵌槽11的卡挡部111卡挡配合，以此构成对嵌入块21的暂定位结构，此状态见图8。最后，穿入定位杆3，即将嵌入块21在长度方向和上下方向均定位，使锁钩212保持在其钩部2121与嵌槽11的卡挡部111卡挡配合的状态，即构成真正锁定状态，如图9所示。上述为嵌入块21嵌入嵌槽11的过程，将嵌入块21从嵌槽11中取出的过程即相反，先卸掉定位杆3，此时如图3，然后以外力(一般是人工取出)向上拉栈板2即带动嵌入块21，锁钩212的钩部2121的脱钩斜面21211与卡档部111上的脱钩斜面1111滑动配合，使锁钩212向内转，钩部2121脱出卡档部111，如图7和图6所示，然后即可直接取出，如图5和图4所示。
本实施例，在将定位杆3卸掉后，栈板2可在上下方向上嵌入或脱出嵌槽11，当某块栈板2损坏时，坏哪块就直接卸下和安装那一块即可，方便性大幅提高；并且，在定位杆3穿置的装配状态下，嵌入块21上的锁钩212被锁定不能动，使钩部2121与卡挡部111保持卡挡状态，此时嵌入块21与嵌槽11的配合形式等同于现有技术，嵌入块21在上下方向上是不能脱出嵌槽的，故而本实施例保留了现有技术的栈板2与支撑梁1连接可靠的优点。
上述实施例不较佳方案，实际中，还可有以下变化：
1、所述嵌入块21中，主体211可仅一侧设锁钩212，以单边锁钩212与嵌槽11的卡挡部111卡挡配合，这也是可行的。
2、所述凹槽2112的截面可以是小于或等于半圆的圆缺形，凸出部2123沿嵌槽11宽度方向嵌入凹槽2112。
3、所述卡挡部111的上沿还设有与锁钩212的钩部2121的外侧底沿配合的配合斜面1112，这一特征不是必要的，实际中没有这个配合斜面1112也可行，在向下嵌入的较大压力下，锁钩212的钩部2121必然会越过卡挡部111，或者在侧向上以外力抵压一下锁钩212即可。
4、钩部2121上设有脱钩斜面21211，而卡挡部111上也对应设与脱钩斜面21211配合的脱钩斜面1111，实际中，脱钩斜面21211和脱钩斜面1111选择其一也可达到同样的脱钩效果。
5、所述定位杆3可以两头都突出于支撑梁1，也可以仅一头突出于支撑梁1，甚至 定位杆3仅穿透嵌槽11的一侧壁即可，而另一侧壁不穿透，或者是不穿到都可。
6、所述锁钩212内侧还设有一面朝上的台阶定位面2122，这个台阶定位面2122不是必要的，实际中可以没有。比如，当锁钩212的厚度够厚时，定位杆与锁钩212上的通孔配合即可达到嵌槽11的长度方向和上下竖直方向上的锁定效果，就不必再设台阶定位面2122。或者，所述锁钩212具有两个平行的竖向锁钩壁，这两竖向锁钩壁相平行间隔设置，两竖向锁钩壁均对应定位杆3开设有通孔，这么定位杆3穿置在这两壁的通孔中，也同样保证了较好的受力承载能力。
上述实施例只为说明本发明的技术构思及特点，其目的在于让熟悉此项技术的人士能够了解本发明的内容并据以实施，并不能以此限制本发明的保护范围。凡根据本发明精神实质所作的等效变化或修饰，都应涵盖在本发明的保护范围之内。
