V型锁式接链环是只可用于立环使用，由于采用了不与链轮接触的立式连接，所以可以防止链轮由于制造误差对接链环造成的损坏，提高了接链环的使用寿命。V型锁式接链环可以与D级链条配合使用。

V lock connectors are designed specially for joining the mining chain in vertical plane of the chain only ,without directly engaged with the sprocket which may cause abrasion. This kind of connector can be fitted with chain connector in Grade 100 and leads the longer work life

    “V型锁”接链环是专门为连接圆环链和“紧凑”链而设计。因为在制造过程中选择了富含Cr、Ni、Mo合金元素的高合金钢原材料和多重热处理工艺，具有非常高的拉伸性能和疲劳寿命。 

    这种接链环只可垂直使用，其外形大小符合DIN 22258 part 3标准要求，并经过精心设计，以确保与配套链轮的配合。   “V型锁”接链环的重量比其它类型接链环较轻。V型锁式接链环装配一定要注意装配方向，保证箭头方向与传动方向一致。

    V lock connectors have benn designed specially for joining together  Mining chains of either round like compact con-figuration .the tensile and fatigue performance is particularly impressive and has been achieved by careful selection of raw material and heat treatment during the manufacruring process.

     the connectors which are for use in the vertical plane only are produced dimensionally in accordance with DIN22258 part 3 and are extremely sprocket  friendly where these have been designed with this specification in mind.

     V lock connectors are lighter in weidht compared with the equivalent chainlock connector .Notice the direction when link the Vlock connector with the chain .Keep the arrow in the connector align with the direction of the transmission.
