Description
Technical field
The utility model relates to technical field of engines, especially relates to a kind of oil drain plug of oil pan.
Background technique
Purge cock is applied on engine sump tank, drains the oil and the function of sealing oil sump inner engine oil while mainly playing change engine oil more.Because purge cock role is very simple, therefore the purge cock using on current oil sump, its structure is generally that a simple bolt adds seal ring, or an additional magnetic core is used for adsorbing the metal impurities in machine oil in plug screw.The mounting point of oil drain plug of oil pan on motor is lower, carrying the lubricant oil of motor, bear larger oil liquid pressure, so in the time draining the oil, there is larger impulse force in machine oil, is difficult to control the dismounting of purge cock, if control bad, purge cock is easy to be washed away by machine oil, causes machine oil unrestrained.Machine oil is spouting under pressure in addition, and range is far, is not easy to collect the machine oil changed, machine oil be sprayed everywhere, easily pollute working site.
What prior art Patent application number was 200720036188.0 realize drains the oil controlled a kind of purge cock structure as shown in Figure 1, this purge cock comprises purge cock body 1, purge cock nut 13 and be located at plug screw screw thread on purge cock body, on the external cylindrical surface of the end of purge cock body 1, if protruding backing pin, the backing pin circumference chute that installs the backing pin straight runner being mated and be attached thereto in the corresponding positions of spiro pluging hole, the blind hole shape oil duct 14 of draining the oil is set on the axis of purge cock, on purge cock body 1 wall that plug screw oil outlet 15 arranges, when plug screw screw thread and spiro pluging hole internal thread unscrew lucky disengaging and coordinate, can realize and draining the oil.It is to be coordinated and realized by threaded plug screw and special spiro pluging hole that this purge cock is realized the controlled mode of draining the oil, and need to carry out special processing processing to the oil sump spiro pluging hole that plug screw is installed, and has increased processing cost; Purge cock need to unscrew the screw thread of cooperation in the time draining the oil, difficulty that may be certain in the situation that there is no driver's tool; After repeatedly changing oil, drain oil may stop up, and need to carry out periodic cleaning to purge cock.
Model utility content
Technical problem to be solved in the utility model is: a kind of oil drain plug of oil pan is provided, not only effectively preventing from dismantling purge cock in purge cock process is flushed away, and all of purge cock valve is general part, interchangeability is good, has reduced processing cost.
Solve the problems of the technologies described above, the technical solution of the utility model is: oil drain plug of oil pan, comprise the purge cock body with oil outlet, in described purge cock body, be provided with oil drain canal, described oil drain canal is communicated with described oil outlet, one end of described purge cock body is provided with purge cock nut, the other end of described purge cock body is provided with the screw thread assembly department suitable with the fuel outlet of described oil sump, in described purge cock body, be provided with the floating ball valve that is communicated with or disconnects described oil drain canal, the both sides that are positioned at floating ball valve in described purge cock body are provided with two seal washers, described floating ball valve is provided with valve rod by fastening piece, described valve rod stretches out described purge cock body, described valve rod is provided with handle.
Preferably, described purge cock body is provided with a boss, and described boss is arranged between described purge cock body and handle, and described boss is provided with a block, and described handle is provided with the swivelling chute suitable with described block.
Adopt technique scheme, the beneficial effects of the utility model are: owing to being provided with floating ball valve in purge cock body, the logical valve rod that is provided with of floating ball valve, lock pin is provided with handle, can realize easily the switching of purge cock, can effectively realize and drain the oil controlledly, the convenient machine oil of changing of collecting, also can facilitate machine oil sampling.This oil drain plug of oil pan not only effectively prevents from dismantling purge cock in purge cock process and is flushed away, and all of purge cock valve is general part, and interchangeability is good, has reduced processing cost.
Because purge cock body is provided with a boss, boss is provided with a block, and handle is provided with the swivelling chute suitable with block, can avoid handle to rotate freely, and can ensure the reliability of purge cock work.
