An upper clamping groove is arranged on the circumference of the upper portion of the side face of the connector, a lower clamping groove is arranged on the circumference of the lower portion of the side face of the connector, an upper sealing ring which has an O-shaped cross section is arranged in the upper clamping groove in a limiting and clamping mode, a lower sealing ring which has an O-shaped cross section is arranged in the lower clamping groove in a limiting and clamping mode, an oil level gauge tube head is arranged on the connector in a sleeved mode and in interference fit with the upper sealing ring and the lower sealing ring, and a lock hook used for locking the dustproof cover on the upper end face of the oil level gauge tube head is fixedly arranged on the upper portion of the outer wall of the oil level gauge tube head. The bi-directional sealing locking oil level gauge has a good sealing property and can effectively prevent water, gas and dust from entering an engine, and quality of engine oil in the engine can be improved tremendously.
Description
Technical field
The utility model relates to a kind of engine fittings, specifically a kind of two way sealed locking oil rule.
Background technique
Engine motor oil is the lubricant oil of motor moving element, oil rule not only can check the height of engine motor oil pasta, and the composition that can also check up Engine oil by oil rule, aging, rotten situation, thereby the machine oil to motor is in time changed, avoid motor therefore to cause bent axle, piston, link motion assembly earlier period damage, thereby guaranteed the normal operation of motor, can say that the rationality of oil rule structure to guaranteeing the normal operation of motor, plays very important effect.
In view of above situation, very high requirement has been proposed for sealing and the assembly reliability of oil rule.Require the oil rule good seal, in use must not occur getting loose, machine oil leaks outside and steam, dust enter the phenomenons such as engine crankcase.If above-mentioned phenomenon occurs, will cause that engine motor oil is rotten, the serious consequences such as insufficient lubrication, scuffing of cylinder bore appear in motor.
But, the oil rule that uses in the market exist one-way sealing, pulling-out force little, seal not the defective such as consolidation, machine oil occurs easily to leak outside, steam, dust enter the phenomenons such as engine crankcase.
Summary of the invention
The defective that the utility model exists in order to remedy existing oil rule provides a kind of two way sealed locking oil rule.
The utility model is achieved through the following technical solutions: two way sealed locking oil rule, comprise the blade of being made by wire rope, be fixedly connected on the draw ring of blade upper end portion, be in series with the dust cover of pie on the blade of draw ring below, be in series with columned joint on the blade of dust cover below, the axis at the axis at dust cover and joint place and blade place is located along the same line, top, described joint side, the bottom has upper draw-in groove along circumference respectively, lower bayonet slot, upper draw-in groove, in the lower bayonet slot respectively limiting card be provided with the upper seal ring that the cross section is " O " shape, lower seal, be socketed with on the described joint and upper seal ring, the cylindrical oil rule tube head of lower seal interference fit, the outer wall top of oil rule tube head is installed with the latch hook that dust cover is lock onto oil rule tube head upper-end surface.
Upper draw-in groove on the joint, lower bayonet slot respectively and the limiting card establishing between the upper seal ring, lower seal close, can effectively avoid causing the problems such as seal ring (upper seal ring, lower seal) dissociates, gets loose because of engine vibration.The interference fit of upper seal ring, lower seal and oil rule tube head is so that sealing consolidation, reliable.
During concrete the use, in two way sealed locking oil rule insertion machine tubing and casing described in the utility model, namely the oil gauge pipe headgear enters in the machine oil sleeve pipe.Because upper seal ring, lower seal become sealing with the oil gauge pipe capitiform, form sealing between dust cover and the oil rule tube head, so that in-engine machine oil can not overflow from the motor oil filler, have good anti-steam, dust effect, guidance quality is good, has improved again the steadiness of oil rule assembling simultaneously.When needs are checked the machine oil consumption, extinguish motor, adjust the latch hook position, extract the blade that is in series with dust cover and joint by draw ring, by checking the oil trace position of machine oil on blade, determine the height of engine interior machine oil pasta, and judge whether that according to actual conditions needs add machine oil.
Two way sealed locking oil rule novel structure described in the utility model, reasonable in design, operation is simple, practical, has good sealing, effectively anti-aqueous vapor, dustproof, greatly improved engine motor oil quality situation, prolonged for 20% drain period, reduced more change engine oil number of times, improved economic benefit, reduce the wearing and tearing of motor, improved the working life of car load.
Description of drawings
Fig. 1 is the structural representation of two way sealed locking oil rule described in the utility model.
Fig. 2 is the sectional view of joint.
Among the figure: 1-blade, 2-draw ring, 3-dust cover, 4-joint, the upper seal ring of 5-, 6-lower seal, 7-oil rule tube head, 8-latch hook, the upper draw-in groove of 9-, 10-lower bayonet slot.
Embodiment
Two way sealed locking oil rule, comprise the blade 1 of being made by wire rope, be fixedly connected on the draw ring 2 of blade 1 upper end portion, be in series with the dust cover 3 of pie on the blade 1 of draw ring 2 belows, be in series with columned joint 4 on the blade 1 of dust cover 3 belows, the axis at the axis at dust cover 3 and joint 4 places and blade 1 place is located along the same line, top, described joint 4 side, the bottom has upper draw-in groove 9 along circumference respectively, lower bayonet slot 10, upper draw-in groove 9, lower bayonet slot 10 interior respectively limiting cards are provided with the upper seal ring 5 that the cross section is " O " shape, lower seal 6, be socketed with on the described joint 4 and upper seal ring 5, the cylindrical oil rule tube head 7 of lower seal 6 interference fit, the outer wall top of oil rule tube head 7 is installed with the latch hook 8 that dust cover 3 is lock onto oil rule tube head 7 upper-end surfaces.
During concrete the manufacturing, the diameter of the joint 4 of described lower seal 6 belows from top to bottom reduces gradually, can be so that in the joint 4 insertion machine dipstick tube heads.The inside and outside diameter in the bottom of oil rule tube head 7 all from top to bottom reduces gradually.Can be so that in the oil gauge pipe head insertion machine tubing and casing.
Described upper seal ring 5, lower seal 6 are all made by acrylate rubber.Acrylate rubber (be called for short ACM) is the elastomer that get through copolymerization take acrylate as main monomer, has oil resistant, high temperature resistant, ageing-resistant, anti-ozone, cost low, the characteristic of the excellence such as good manufacturability.
Further, described oil rule tube head 7 is made by Q235A low carbon steel.Q235A low carbon steel has good toughness, strength and stiffness, has guaranteed the seal request of oil rule tube head and seal ring (upper seal ring, lower seal).
