具体实施方式Detailed ways
下面结合附图并通过具体实施方式来进一步说明本实用新型的技术方案。The technical scheme of the utility model will be further described below in conjunction with the accompanying drawings and through specific embodiments.
如图1、图2所示，一种货车车厢暗锁结构，包括车厢和铰接在车厢后部或侧部两旁的车厢门3，车厢门3的内侧壁下端部固定连接有连接板14，连接板14活动连接有插销限位板12，车厢包括车厢底板1，车厢底板1连接有向下延伸的车厢底板翻边2，车厢底板翻边2连接有可上下运动的插销组件；As shown in Figures 1 and 2, a built-in lock structure for a truck compartment includes a compartment and compartment doors 3 hinged on both sides of the rear or sides of the compartment, and the lower end of the inner side wall of the compartment door 3 is fixedly connected with a connecting plate 14, the connecting plate 14 is movably connected with a latch limiting plate 12, the carriage includes a carriage floor 1, the carriage floor 1 is connected with a carriage floor flanging 2 extending downward, and the carriage floor flanging 2 is connected with a latch assembly that can move up and down;
锁闭时，插销限位板12随着车厢门3的关闭而自动向上翻转以搭接在车厢底板1上，插销组件自下而上穿过车厢底板1及插销限位板12；When locking, the latch limiting plate 12 is automatically turned upwards with the closing of the compartment door 3 to overlap the compartment floor 1, and the latch assembly passes through the compartment floor 1 and the latch limiting plate 12 from bottom to top;
开锁时，插销组件自上而下移出插销限位板12，插销限位板12随着车厢门3的打开而自动向下翻转以贴附于车厢门3的内侧壁上。When unlocking, the latch assembly moves out of the latch limiting plate 12 from top to bottom, and the latch limiting plate 12 automatically turns downwards to be attached to the inner side wall of the compartment door 3 as the compartment door 3 is opened.
该货车车厢暗锁结构，通过设置在车厢底板向下延伸的车厢底板翻边上，因而在操作时需要将手伸入车厢底部进行操作，操作人员站在车厢的外侧不容易直接观察到，具有较好的隐蔽性，且插销组件上下运动的方式使得操作方便，不仅能够有效防止厢门自动打开或恶意打开，起到较好的防盗效果；另外，车厢门打开后，插销限位板翻转并贴附在车厢门的内侧壁，避免其凸出而挂扯物品或者伤害操作人员，使得操作更加方便，占用空间小，广泛应用于物流、快递、道路运输设备上，还可以应用于集装箱，其应用范围广。The built-in lock structure of the truck compartment is arranged on the flange of the compartment floor that extends downward from the compartment floor, so it is necessary to extend the hand into the bottom of the compartment during operation, and it is difficult for the operator to directly observe it when standing on the outside of the compartment.

当插销柄8的底侧与位于下方的插销安装凸起5的顶部相抵时，插销7移出插销限位板12。When the bottom side of the latch handle 8 abuts against the top of the lower latch mounting protrusion 5 , the latch 7 moves out of the latch limiting plate 12 .
利用插销柄8的限位，操作人员在操作时无需通过观察就能感知到是否锁紧到位或者打开到位，因而无需弯腰或者将头伸入车厢底板1的底部观看，降低操作人员的劳动强度，降低危险。Utilizing the position limit of the latch handle 8, the operator can sense whether the locking is in place or the opening is in place without observing during operation, so there is no need to bend down or put his head into the bottom of the compartment floor 1 to watch, reducing the labor intensity of the operator , to reduce the risk.
优选的，插销柄8开设有插销柄连接孔9，车厢底板翻边设置有锁舌10，插销柄8通过锁舌10伸入插销柄连接孔9形成配合，以限位插销7。进一步通过锁舌10与插销柄连接孔9进行限位，当插销7上移到位后，可以直接固定，避免因松手后自动掉落，进一步优选的，锁舌10开设有锁舌孔11，当插销柄8与锁舌10配合后，锁舌孔11连接有挂锁，利用挂锁进一步起到固定可靠，达到双重保险左右能够。当然，此处的挂锁也可以是其他的销钉或者铁丝之类的，只要是能够起到固定作用即可。Preferably, the latch handle 8 is provided with a latch handle connecting hole 9 , and the flange of the compartment floor is provided with a deadbolt 10 , and the latch handle 8 extends into the latch handle connecting hole 9 through the deadbolt 10 to form a fit to limit the latch 7 . Further, the locking bolt 10 and the bolt handle connection hole 9 are used to limit the position. When the bolt 7 moves up to the position, it can be fixed directly to avoid falling automatically after letting go. Further preferably, the dead bolt 10 is provided with a dead bolt hole 11. When After the latch handle 8 cooperates with the dead bolt 10, the dead bolt hole 11 is connected with a padlock, and the padlock is further used to fix reliably, so that double insurance can be achieved. Of course, the padlock here can also be other pins or iron wires, as long as it can play a fixing role.
优选的，插销限位板12开设有插销限位孔13，车厢底板1开设有通孔，通孔、插销限位孔13均与插销安装孔6同轴设置。Preferably, the bolt-limiting plate 12 is provided with a bolt-limiting hole 13 , and the compartment floor 1 is provided with a through hole, and both the through-hole and the bolt-limiting hole 13 are arranged coaxially with the bolt installation hole 6 .
在本实施例中，插销安装板4、插销限位板12等均为不锈钢材质的硬质的结构，其具体尺寸为5mm*40mm*L，L根据后门框结构确定，并且其分别与车厢底板翻边2、或者车厢门3的连接可以使用M8*35或M8*40内六角螺栓及螺母，插销组件中的插销7的直径≥12mm，其实现简单容易，材料简单易见，成本低。In this embodiment, the bolt mounting plate 4 and the bolt limiting plate 12 are all hard structures made of stainless steel, and their specific dimensions are 5mm*40mm*L. The flange 2 or the compartment door 3 can be connected using M8*35 or M8*40 hexagon socket head bolts and nuts. The diameter of the bolt 7 in the bolt assembly is ≥12mm, which is simple and easy to implement, easy to see and low in cost.
具体安装步骤如下：The specific installation steps are as follows:
1、车厢的后下门框若为槽钢结构，需要焊接固定板(板厚3-5mm)或切缺口，焊接位置为距离车厢中线向右150mm-250mm；下门框若为矩形方管，则省略此步骤；1. If the rear lower door frame of the carriage is of channel steel structure, it needs to weld the fixing plate (thickness 3-5mm) or cut a gap. The welding position is 150mm-250mm to the right from the middle line of the carriage; if the lower door frame is a rectangular square pipe, omit it this step;
2、将插销组件通过插销安装板4贴合在车厢底板翻边2的表面，用粉笔在车厢底板1的底面上对应插销7画出通孔位置，用电钻从下向上在车厢底板1上钻通孔(钻头直径5-8mm均可)；2. Fit the bolt assembly on the surface of the flange 2 of the carriage floor through the bolt installation plate 4, use chalk to draw the position of the through hole corresponding to the bolt 7 on the bottom surface of the carriage floor 1, and use an electric drill to drill on the carriage floor 1 from bottom to top Through hole (drill diameter 5-8mm is acceptable);
3、关闭右侧门，根据通孔的位置，根据插销限位板12上的插销限位孔13与通孔对应的尺寸，焊接连接板14；复合板车厢后门使用两个内六角螺栓连接；3.
