技术领域 Technical field
本发明属于搭建结构中特别是用于商品交易会或商店结构装配 ***中的连接锁件，具体是一种用来连接装配***中其它 4. 3槽口支 撑型材或装配部件的锁具。 背景技术 The present invention is a connection lock in a construction structure, particularly for use in a trade fair or store structure assembly system, and more particularly a lock for attaching other 4. 3 notch support profiles or assembly components in an assembly system. Background technique
在原先的 4. 3槽口展览展示***中， 连接方式采用弹性簧片锁， 由于弹性簧片锁包括锁壳， 簧片以及偏心轮， 其锁壳与簧片分为内外 两层， 不仅制造复杂， 装配麻烦， 而且当运用到小槽口时， 这种设计 会进一步减少簧片的强度， 从而导致连接强度的下降； 现在的弹性簧 片锁还存在一个缺点， 就是只能适用于 90度方向连接， 对于个性化 要求越来越多的今天， 只是 90度的连接方式在很多展览展示结构中 具有局限性， 根据造型需要， 要求在 4. 3槽口展览展示***中有许多 斜向连接， 光靠机械连接不能满足展览快速拆装的要求。 发明内容 In the original 4.3 slot display system, the connection method uses elastic reed lock. Since the elastic reed lock includes the lock case, the reed and the eccentric wheel, the lock case and the reed are divided into inner and outer layers, which are not only manufactured. Complex, complicated to assemble, and when applied to small slots, this design will further reduce the strength of the reed, resulting in a decrease in the strength of the connection; the current elastic reed lock has a drawback, that is, it can only be applied to 90 degrees. Directional connection, for more and more personalized requirements today, only the 90 degree connection method has limitations in many exhibition display structures. According to the modeling needs, there are many oblique connections in the 4.3 slot display system. , the mechanical connection can not meet the requirements of the rapid disassembly of the exhibition. Summary of the invention
本发明所要解决的技术问题是针对上述现有技术的不足，提供一 种制造方便，可直接与搭建结构中其它 4. 3槽口型材或装配部件实现 连接的撑幵锁具。 The technical problem to be solved by the present invention is to provide a brace lock which is easy to manufacture and can be directly connected with other 4.3-notch profiles or assembly members in the construction structure in view of the above-mentioned deficiencies of the prior art.
