易熔合金消防喷淋头一般包括框架、分别设于框架两端的管接头和溅水盘、设于框架内的支撑件，管接头上设有喷水口，喷水口上设有密封用的堵头，支撑件用于压住堵头，支撑件由两个以上元件组合成不稳定的支撑结构，依赖易熔合金锁定。在冷态时，易熔合金有足够的强度，不稳定的支撑结构仍然保持稳定支撑着密封件。

The fusible alloy fire sprinkler head generally includes a frame, pipe joints and splash pans respectively arranged at both ends of the frame, and supports arranged in the frame. The pipe joints are equipped with water spray ports, and the water spray ports are equipped with sealing plugs. The supports are used to press the plugs. The supports are composed of more than two components to form an unstable support structure, which depends on the fusible alloy to lock. In the cold state, the fusible alloy has sufficient strength, and the unstable support structure still stably supports the seal.

当火灾发生时，易熔合金熔化失去锁定力，不稳定的支撑结构解体，密封件失去支撑后被水流冲开，喷头开始喷水灭火。现有的易熔合金支撑件结构比较复杂，加工和安装不方便，如称为一种易熔合金喷头的，公开了一种由支撑架、支架、定位板、顶子、易熔合金件组成的支撑件。

When a fire occurs, the fusible alloy melts and loses its locking force, the unstable support structure disintegrates, the seal loses its support and is washed away by the water flow, and the sprinkler starts to spray water to extinguish the fire. The existing fusible alloy support has complex structure and inconvenient processing and installation. For example, the patent called a fusible alloy nozzle discloses a support composed of a support frame, a support, a positioning plate, a top and a fusible alloy part.

消防喷头的易熔合金动作元件，包括上顶板、下顶板，上顶板包括依次设置的横板部、弯折部和竖板部，下顶板的顶面抵住横板部的底面，竖板部的内侧面贴住下顶板的内侧面，竖板部的内侧面和下顶板的内侧面上均设有滚花或网纹，竖板部和下顶板的贴合处设有易熔合金，下顶板的上部与弯折部构成容纳腔，容纳腔内设有易熔合金。

The fusible alloy action element of the fire sprinkler includes an upper top plate and a lower top plate. The upper top plate includes a transverse plate part, a bending part and a vertical plate part arranged in sequence. The top surface of the lower top plate is against the bottom surface of the transverse plate part, the inner surface of the vertical plate part is close to the inner surface of the lower top plate, the inner surface of the vertical plate part and the inner surface of the lower top plate are both provided with knurling or reticulation, and the joint between the vertical plate part and the lower top plate is provided with fusible alloy, The upper part of the lower top plate and the bending part form a holding cavity, and a fusible alloy is arranged in the holding cavity.

优选的，下顶板的顶面中部设有凹槽，凹槽与横板部的底面之间设有易熔合金。

Preferably, a groove is arranged in the middle of the top surface of the lower top plate, and a fusible alloy is arranged between the groove and the bottom surface of the transverse plate.

优选的，下顶板的上部和上顶板的弯折部均为下宽上窄的形状。

Preferably, the upper part of the lower top plate and the bending part of the upper top plate are in the shape of wide at the bottom and narrow at the top.

优选的，横板部的顶面设有用于定位螺丝的凹孔，下顶板的底面中部设有凸点。

Preferably, the top surface of the transverse plate part is provided with a concave hole for positioning screws, and the middle part of the bottom surface of the lower top plate is provided with a convex point.

优选的，上顶板和下顶板为均为磷铜板。

Preferably, both the upper and lower top plates are phosphorous copper plates.

川消小编认为通过采用上述的技术方案，本实用新型的有益效果是：本实用新型为上顶板和下顶板通过易熔合金焊接而成，结构简单。而且上顶片和下顶片的简单形状，只需冲压机冲压一次就可以成型，加工方便。

Chuanxiao Xiaobian believes that by adopting the above technical scheme, the beneficial effect of the utility model is that the upper and lower top plates are welded by fusible alloy, and the structure is simple. Moreover, the simple shape of the upper top sheet and the lower top sheet can be formed by stamping with a stamping machine once, which is convenient for processing.

易熔合金设置在容纳腔、竖板部的滚花贴合面以及下顶板的凹槽，使上顶板的横板部、弯折部和竖板部均与下顶板焊接，连接牢固。下顶板底部的凸点作为支点，当热熔合金熔化时，更容易瓦解。

The fusible alloy is arranged in the holding cavity, the knurled fitting surface of the vertical plate part and the groove of the lower top plate, so that the transverse plate part, bending part and vertical plate part of the upper top plate are welded with the lower top plate and firmly connected. The convex point at the bottom of the lower top plate is used as the fulcrum, which is easier to collapse when the hot-melt alloy melts.
