Description
防脱碗头挂板 Anti-off bowl head hanging board
技术领域 Technical field
本发明属于高压电线路金具的连接装置， 具体地说是一种供与高压电线 路金具的球头挂环连接的防脱碗头挂板。 背景技术 The invention belongs to a connecting device for a high-voltage electric circuit fitting, in particular to a anti-off bowl hanging plate for connecting with a ball-end hanging ring of a high-voltage electric wire fitting. Background technique
为了防止球头挂环从碗头挂板中脱落， 现有的碗头挂板中设有由不锈钢 扁钢压型结构的弹簧插销构成的防脱装置。当球头挂环和碗头挂板处于垂直 状态或倾斜角不大时，在重力和弹簧插销锁紧力的作用下，球头挂环 ^艮难从 碗头挂板中脱落。 但由于高压电线路长期处在野外十分恶劣的自然环境中， 在飓风等大风力的交变作用下， 会因 1 )球头挂环的球头与弹簧插销的立面 不断发生撞击性摩擦而使弹簧插销的立面严重磨耗断脱，导致球头从碗头挂 板的倒 T型槽中脱出； 或因 2 )球头挂环的球头在摆动或移动时产生的巨大 纵向摩擦力而使弹簧插销的钩头变形或断裂， 导致球头从碗头挂板的倒 T 型槽中脱出。 亦可能因弹簧插销的材质丧失弹性而失去对球头的制约，导致 球头从碗头挂板的倒 T型槽中脱出。 总之， 由于现有弹簧插销结构上的不 压线路遭受重大损失。 发明内容 In order to prevent the ball end hanging ring from falling off the bowl hanging plate, the existing bowl head hanging plate is provided with an anti-off device composed of a spring pin of a stainless steel flat steel pressing structure. When the ball head hanging ring and the bowl head hanging plate are in a vertical state or the tilt angle is not large, under the action of the gravity and the spring pin locking force, the ball end hanging ring is difficult to fall off from the bowl hanging plate. However, because the high-voltage electric line has been in the harsh natural environment for a long time in the wild, under the alternating effect of large winds such as hurricane, the collision between the ball head of the ball-end ring and the façade of the spring pin is constantly caused. However, the façade of the spring pin is severely worn and broken, resulting in the ball head coming out of the inverted T-shaped groove of the bowl hanging plate; or 2) the large longitudinal friction generated when the ball head of the ball sling is swinging or moving. The hook of the spring pin is deformed or broken, causing the ball to come out of the inverted T-shaped groove of the bowl hanging plate. It is also possible that the material of the spring pin loses its elasticity and loses its restriction on the ball head, so that the ball head is released from the inverted T-shaped groove of the bowl hanging plate. In summary, significant losses are due to the uncompressed lines on existing spring latch constructions. Summary of the invention
本发明的目的是为了克服上述不足提供一种结构筒单、 拆装和检修方 便、 防脱效果好的防脱碗头挂板。 SUMMARY OF THE INVENTION The object of the present invention is to provide an anti-off bowl hanging plate with a structural unit, a disassembly, assembly and maintenance, and a good anti-off effect.
