Description

Leak protection watercolor pencil Technical Field The utility model relates to the technical field of watercolor pencils, in particular to a leakage-proof watercolor pencils. Background In order to solve the defect, the ink bag and the pen body are separated, stored and transported by a part of improvement scheme, and the ink bag is manually assembled when in use, so that the risk of liquid leakage is reduced, the operation steps are complicated, and the convenience of products is destroyed. Disclosure of utility model The technical problem to be solved by the utility model is to provide the leakage-proof watercolor pencil, which can avoid the condition of liquid leakage in the transportation and storage processes in a mechanical blocking manner while maintaining convenience, so that the watercolor pencil is convenient to store, transport and use. The technical scheme includes that the leak-proof watercolor pen comprises a pen point, a pen head rod and a pen body rod, wherein the front end of the pen point is positioned outside the pen head rod, the rear end of the pen point is fixed inside the pen head rod, ink is poured into the pen body rod, the pen head rod is in threaded connection with the pen body rod, a blocking ring is arranged between the pen head rod and the pen body rod and used for preventing the pen head rod and the pen body rod from being in complete threaded connection, a protruding block is fixed inside the pen head rod, a valve component is fixed inside the pen body rod and connected with the protruding block, and the valve component is used for preventing the ink from flowing into the pen head rod. Further, the valve assembly comprises a valve core and a valve seat fixed in the pen body rod, a through groove with a narrow front and a wide rear is formed in the valve seat, the valve core slides in the through groove, when the valve core is positioned at the front end of the through groove, the valve assembly is in a closed state, the pen body rod is not communicated with the pen point rod, when the valve core is positioned at the rear end of the through groove, the valve assembly is in an open state, and the pen body rod is communicated with the pen point rod. Further, the pen body rod is divided into a connecting section and a main body section, the valve seat is fixed in the connecting section, threads are arranged on the outer portion of the connecting section, and the outer shell of the main body section is made of soft plastic which can be extruded. Further, one end of the lug is butted with the valve core, the other end of the lug is butted with the pen point, the outer diameter of one end of the lug butted with the valve core is the same as the outer diameter of the valve core, a through ink flow groove is formed in the lug, when the blocking ring is removed, the lug pushes the valve core to enable the valve core to move towards the rear end of the through groove, the lug is clamped into the front end of the through groove, so that the valve assembly is opened, and ink flows from the pen body rod to the pen point through the ink flow groove.
