The connecting pipe 4 is generally a hollow steel pipe.
如图 2所示，它是现有集装箱锁头安装大托架后的示意图。一般 在连接管 4的外部套设一大托架 6， 其中大托架 6的弯头 Ί被卡在根 部 2的端面和连接管 4的焊接头 A之间， 二者有一段安全距离 B。 一 般在连接管 4和大托架 6之间还有一圈衬套 5。这样大托架 6在安全 距离 B之向可以有一定的活动余地。  As shown in Figure 2, it is a schematic view of the existing container lock after installing the large bracket. Generally, a large bracket 6 is placed outside the connecting pipe 4, wherein the elbow of the large bracket 6 is caught between the end face of the root 2 and the welding head A of the connecting pipe 4, which have a safe distance B. There is also a bushing 5 between the connecting pipe 4 and the large bracket 6. Such a large bracket 6 can have a certain amount of room for movement in the direction of the safe distance B.
上述集装箱锁头有一个缺点， 就是连接管 4被直接焊接在柄部 3 上， 其焊接方式采用搭接的接头形式（图中 A处)， 而由于搭接结构 特点， 不可避免的存在应力集中， 而锁杆在使用过程中， 特别是海运 途中， 集装箱在重载时， 船体受到海浪颠簸， 锁头的连接管 4也会不 " 断受到拉伸和压缩两种不同的力的交替作用，长期如此，搭接的结构 形式由于应力集中产生的可能性越大，锁杆在连接管 4处的焊接容易 受到破坏， 导致锁头脱落而失效。  The above container lock has a disadvantage in that the connecting pipe 4 is directly welded to the shank 3, and the welding method is in the form of a lap joint (at the point A in the figure), and the stress concentration is inevitable due to the lap joint structure. When the lock bar is in use, especially on the sea, when the container is under heavy load, the hull is bumped by the waves, and the connecting pipe 4 of the lock is not broken and subjected to the alternating effects of stretching and compression. For a long time, the greater the possibility that the overlapping structure is generated due to stress concentration, the welding of the lock bar at the connecting pipe 4 is easily damaged, and the lock head is detached and fails.

最佳实施例  Best embodiment
下面结合附图和具体实施方式对本发明做进一步阐述。  The present invention will be further described below in conjunction with the drawings and specific embodiments.
如图 3、 4所示， 它们分别是本发明集装箱锁头的示意图和本发 明集装箱锁头安装大托架后的示意图。和现有技术相比，其中很多地 方类似， 比如它也包括齿部 10、 根部 11和柄部 12。 齿部 10用于和 锁座的齿部进行卡合， 柄部 12上用于焊接连接管 14， 起到连接上下 锁头用。 连接管 14一般为中空的钢管。  As shown in Figures 3 and 4, they are respectively a schematic view of the container lock of the present invention and a schematic view of the container lock of the present invention after the large bracket is mounted. Many of them are similar in comparison to the prior art, for example, it also includes the tooth portion 10, the root portion 11, and the handle portion 12. The tooth portion 10 is for engaging with the tooth portion of the lock seat, and the handle portion 12 is for welding the connecting tube 14 for connecting the upper and lower locks. The connecting tube 14 is generally a hollow steel tube.
另外， 一般在连接管 14的外部套设一大托架 16， 在连接管 14 和大托架 16之间还有一圈衬套 15。 ·  Further, a large bracket 16 is generally provided outside the connecting pipe 14, and a bushing 15 is further provided between the connecting pipe 14 and the large bracket 16. ·
本发明与现有技术最大的区别在于，在柄部 12设有环状突起 13， 连接管 14直接悍接在环状突起 13的一侧， 其中， 环状突起 13的高 度可以使连接管 14与环状突起 13采用对接方式焊接，其中焊点为 D。 大托架 16的弯头 17被卡在根部 11的端面和环状突起 13之间，二者 有一段安全距离^ The greatest difference between the present invention and the prior art is that the handle portion 12 is provided with an annular projection 13 which is directly spliced to one side of the annular projection 13, wherein the height of the annular projection 13 allows the connecting tube 14 to be connected. The annular protrusion 13 is welded in a butt joint manner, wherein the solder joint is D. The elbow 17 of the large bracket 16 is caught between the end surface of the root portion 11 and the annular projection 13 with a safe distance ^
由于焊点 D为对接方式焊接形成，所以其相对于现有技术的搭接 方式焊接形成的焊点牢固。 另外， 由于环状突起 13和根部的位置相 对固定，所以安全距离 H更容易确定和掌握。安全距离 H可以根据集 装箱大托架 17的弯头 71大小以及大托架 17的变形进行确定。  Since the solder joint D is formed by soldering in a butt joint manner, it is firmly soldered to the solder joint formed by the prior art lap joint method. Further, since the positions of the annular projection 13 and the root are relatively fixed, the safety distance H is easier to determine and grasp. The safety distance H can be determined according to the size of the elbow 71 of the large bracket 17 of the container and the deformation of the large bracket 17.
另外，环状突起 13的大小尤其是其厚度根据其受力的大小设定， 而其形状可以为两个共底部的圆锥台。 当然也可以采用圆柱等形状。  Further, the size of the annular projection 13 is particularly set depending on the magnitude of its force, and its shape may be two truncated cones having a common bottom. Of course, a shape such as a cylinder can also be used.
环状突起 13的高度根据连接管 14的靠近环状突起 13—侧的端 面大小设定，一般来讲环状突起 13的直径要与连接管 14的直径相匹 配， 这样是为了实现环状突起 13和连接管 14的对接方式焊接。  The height of the annular projection 13 is set according to the size of the end surface of the connecting tube 14 near the annular projection 13 side. Generally, the diameter of the annular projection 13 is matched with the diameter of the connecting tube 14, so as to achieve the annular projection. 13 is welded to the butt joint of the connecting pipe 14.
工业实用性  Industrial applicability
由于本发明是在现有技术上的改进，在现有集装箱柄部上设置一 用于焊接连接管的环状突起，主要的好处在于由于环状突起可以使连 接管采用对接方式焊接在环状突起上，这样就可以提供连接管的焊接 强度， 进而提高了集装箱的安全性能。  Since the present invention is an improvement in the prior art, an annular projection for welding a connecting pipe is provided on the existing container handle, and the main advantage is that the connecting pipe can be welded in a ring shape by abutting manner due to the annular protrusion. On the protrusions, the welding strength of the connecting pipe can be provided, thereby improving the safety performance of the container.
