Self-locking leakage-proof emulsion pump

The utility model discloses a self-locking leakage-proof emulsion pump, and relates to the technical field of emulsion pumps. The device comprises a pressing head, a main column, a lock cover, screw teeth, a piston, an auxiliary column, a spring, a suction pipe and a glass bead, a clamping strip and a clamping block are fixedly connected to the peripheral side face of the main column, a clamping cover is slidably connected to the peripheral side face of the main column, a notch matched with the clamping strip and the clamping block is formed in one surface of the clamping cover, a through pipeis fixedly connected to the bottom of the locking cover, and a sliding groove is formed in the inner wall of the through pipe. According to the utility model, the clamping strip, the clamping block,the clamping cover, the notch, the through pipe and the sliding groove are designed; the bottom of the sliding groove is in a closed state, liquid in the emulsion pump is prevented from overflowing through the sliding groove, meanwhile, the bottom end of the clamping strip is prevented from moving downwards through the top of the clamping cover, and therefore the main column is prevented from moving downwards, and the problems of waste and pollution caused by leakage of the liquid in the emulsion pump are solved. 本实用新型公开了一种自锁式防泄漏的乳液泵，涉及乳液泵技术领域。本实用新型包括按头、主柱、锁盖、螺牙、活塞、副柱、弹簧、吸管以及玻璃珠，主柱周侧面分别固定连接有卡条和卡块，主柱周侧面滑动连接有卡盖，卡盖一表面开设有与卡条和卡块均匹配的缺口，锁盖底部固定连接有通管，通管内壁开设有滑槽，滑槽上端为开口状态，滑槽上端口延伸至卡盖顶部。本实用新型通过卡条、卡块、卡盖、缺口、通管和滑槽的设计，滑槽底部为封闭状态，避免了乳液泵内的液体通过滑槽溢出，同时使卡盖的顶部阻止卡条底端向下移动，从而阻止了主柱向下移动，避免了乳液泵内的液体发生泄漏，造成浪费，同时造成污染的问题。
