灌缝胶注胶器是一种对混凝土裂缝持压注胶的小型设备，采用注胶活塞和弹簧的灌缝胶注胶器结构的改进,舍去了胶囊,通过在推杆前端固定注胶活塞，在推杆上套置高强度弹簧,在松开推杆的锁扣后，利用高强度弹簧的张力,可推动注胶活塞连同推杆前移,将注胶筒内的胶液完全压出注入建筑结构的裂缝中,价格低廉,，操作方便，施工安全，清洗方便，可多次重复使用。
joint-seal glue injector is a smalldevice which is used to inject the glue into the concrete jointwith the pressure, adopting the glue-injection piston and springstructure design, without the glue bag, fixing the piston in thefront the push rod, installing the high strength spring onto thepush rod, after release the lock latch of the push rod, pushing thepiston and the push rod forward with the tensile force of the highstrength spring, so pressing all of the glue liquid from theglue-injection cylinder into the joint. the injector has manyadvantages, such as the low price, the high cost-efficiency, theconvenient operation, the safe construction, the easy cleaning, andthe repetitious usage.
