Abstract

The invention discloses a blocking mechanism of an oil level indicator pipe. The blocking mechanism comprises a front sleeve body and a back sleeve body, the front portion of the back sleeve body is inserted into a hole of the front sleeve body, a spring is arranged between the front end of the back sleeve body and the inner end face of the front sleeve body, an annular groove is arranged in the inner side of the back portion of the front sleeve body, the annular groove is located in the outer side of the front portion of the back sleeve body, the diameter of the annular groove is gradually changed smaller from the front end to the back end, a hole is formed in the front portion of the back sleeve body, a steel ball is located in the hole, a screw rod is connected with the inner hole of the back sleeve body in a threaded mode, a blocking ring is connected with the front end of the screw rod, and a hand wheel is connected with the rear end of the screw rod. The blocking mechanism is simple in overall structure, tight in blocking and convenient to operate.

Description

technical field [0001] The invention relates to a plugging mechanism for an oil dipstick tube, which is used for plugging an oil dipstick tube of an automobile engine. Background technique [0002] The gas sealing test of the inner cavity channel of the automobile engine is a key process of the engine body assembly production line. The oil dipstick tube must be blocked. There is no good blocking mechanism at present, which brings trouble to the sealing test. In order to tightly seal the oil dipstick Tube operators have used a variety of methods for plugging with unsatisfactory results. SUMMARY OF THE INVENTION [0003] The purpose of the present invention is to provide an oil dipstick tube plugging mechanism with simple structure, tight sealing and convenient operation, and overcome the deficiencies of the prior art. [0004] The oil dipstick tube plugging mechanism of the present invention includes a front cover body and a rear cover body, the front part of the rear cove...
