Detailed Description
As shown in fig. 1, a novel insert oiling stopper structure soon, it is including pulling out structure and locking structure, pull out the structure of inserting and include oiling stopper valve body 1, oiling stopper case 2, valve gap 3 and sealing washer 10, oiling stopper valve body 1 be the assembly base member, in oiling stopper case 2 installation oiling stopper valve body 1, oiling stopper case 2 is the case route of two-way oil circuit, accomplishes two-way opening through the difference of outside atmospheric pressure and internal pressure, valve gap 3 installs the top at oiling stopper valve body 1, the lower extreme at oiling stopper valve body 1 is installed to sealing washer 10, characterized in that: the pulling and inserting structure also comprises a cutting sleeve 4, a pulling and inserting spring 5 and a snap spring 6, wherein the snap spring 6 and the pulling and inserting spring 5 are sequentially arranged on the oil filling plug valve body 1, the cutting sleeve 4 is arranged on the oil filling plug valve body 1, the clamp spring 6 and the pull-plug spring 5 are arranged in the cutting sleeve 4, the cutting sleeve 4 is connected with the valve cover 3 in a sliding way, the locking structure comprises a limiting steel ball 7 and a steel ball limiting sleeve 8, the limiting steel ball 7 and the steel ball limiting sleeve 8 are arranged on a boss of a fuel filler 9 of the hydraulic pump, the oil filling plug valve body 1 is provided with a groove at the position matched with the mounting position of the limiting steel ball 7, the boss wall of the oil filling port 9 of the hydraulic pump is provided with a through hole, the position of the through hole is positioned at the contact position of the clamping sleeve 4 and the steel ball limiting sleeve 8, the diameter of the through hole is matched with the limiting steel ball 7, the limiting steel ball 7 is installed in the through hole, and a groove is formed in the contact position of the steel ball limiting sleeve 8 and the limiting steel ball 7.
Furthermore, cutting ferrule 4 be two concave shape, the internal diameter of upper recess opening and valve gap 3 external diameter phase-match, the internal diameter of lower recess opening and the boss external diameter phase-match of hydraulic pump oil filler hole 9, the middle diameter and the external diameter phase-match of oiling stopper valve body 1.
Furthermore, the diameter of the limiting steel ball 7 is equal to the sum of the length of a through hole of a boss wall of the oil filling port 9 of the hydraulic pump and the depth of a groove of the oil filling plug valve body 1 and the groove of the steel ball limiting sleeve 8.
Furthermore, the snap spring 6 limits the sliding stroke of the clamping sleeve 4 on the valve cover 3, and the snap spring 6 limits the stroke and the disengagement of the clamping sleeve 4.
