Abstract
The utility model discloses a hold down gag for engine oil sprayer, comprising a jam block having a through hole and a female screw; a first flange and a second flange are provided on the two sides of the through hole of the jam block respectively; the first flange leans against one end face of the cylinder cap, while the second flange sticks into the groove of the oil sprayer; the binding bolt crosses the through hole and is connected to the screw thread on the cylinder cap; the female screw is provided inside the through hole of the jam block and has a diameter larger than the diameter of the female screw. The hold down gag is not only fast and reliable, but also convenient for the dismounting of the oil sprayer.
Description
Technical field
The utility model relates to technical field of engines, relates in particular to a kind of hold down gag of engine fuel injector.
Background technique
Oil sprayer is the vitals of motor, and it is fixed in the cylinder head by a hold down gag.Described hold down gag comprises a compact heap, described compact heap is provided with a through hole, the both sides of described through hole are respectively equipped with first flange and second flange, and described first flange is resisted against on the end face of cylinder head, and described second flange stretches in the compressed grooves of oil sprayer.A clamping bolt passes the through hole of compact heap, and its helical thread portion screws in the tapped hole of cylinder head, realizes compressing of oil sprayer.There is a shortcoming during oil sprayer in this structure in dismounting because the air cylinder head structure compactness, screw off clamping bolt after, still be difficult to oil sprayer is taken out in cylinder head, brought inconvenience to maintenance work.
The model utility content
Technical problem to be solved in the utility model is: provide a kind of hold down gag of engine fuel injector, to solve the problem of dismounting oil sprayer inconvenience.
For solving the problems of the technologies described above, the technical solution of the utility model is: the hold down gag of engine fuel injector comprises a compact heap and a clamping bolt that is provided with through hole; The through hole both sides of described compact heap are respectively equipped with first flange and second flange, and described first flange is resisted against on the end face of cylinder head, and described second flange stretches in the groove of oil sprayer; Described clamping bolt passes described through hole and is threaded with cylinder head, and the through hole of described compact heap is provided with the diameter of thread of the diameter of internal thread and described internal thread greater than described clamping bolt.
Because the diameter of internal thread of through hole that is arranged at described compact heap is greater than the diameter of thread of described clamping bolt, clamping bolt can pass from this through hole easily.After screwing clamping bolt, compact heap is fixed in oil sprayer in the cylinder head.Dismounting at first screws off clamping bolt during oil sprayer, screw in then one with suitable screw rod or the special tool of the internal thread of described through hole, compact heap and oil sprayer are taken out in cylinder head together, thereby have solved the problem of oil sprayer dismounting inconvenience.
Description of drawings
Below in conjunction with drawings and Examples the utility model is further specified.
Fig. 1 is the utility model embodiment's a structural representation;
Fig. 2 is the plan view of middle compact heap embodiment illustrated in fig. 1.
Embodiment
As shown in Figure 1, the hold down gag of engine fuel injector comprises a compact heap 4 and a clamping bolt 3 that is provided with through hole 43; Shown in Fig. 1 and Fig. 2 were common, through hole 43 both sides of described compact heap were respectively equipped with first flange 41 and second flange 42, and described first flange 41 is resisted against on the end face of cylinder head 2, and described second flange 42 stretches in the groove of oil sprayer 1.Described clamping bolt 3 passes described through hole 43 and is threaded with cylinder head 2, and the through hole 43 of described compact heap is provided with the diameter of thread of the diameter of internal thread and described internal thread greater than described clamping bolt 3.The length of the internal thread of the described through hole 43 that is arranged at compact heap should guarantee that screw thread has enough intensity, preferably through whole through hole 43.
Because the diameter of internal thread of through hole 43 that is arranged at described compact heap is greater than the diameter of thread of described clamping bolt 3, clamping bolt 3 can pass from this through hole 43 easily.After screwing clamping bolt 3, compact heap 4 is fixed in oil sprayer 1 in the cylinder head 2.Dismounting at first screws off clamping bolt 3 during oil sprayer 2, screw in then one with suitable screw rod or the special tool of the internal thread of described through hole 43, with the taking-ups in the cylinder head 2 together of compact heap 4 and oil sprayer 1.In other words, by said structure, this hold down gag is not only fastening reliable, and has had the effect of dismounting oil sprayer, has brought convenience for the dismounting of oil sprayer.
Claims (2)
1, the hold down gag of engine fuel injector comprises a compact heap (4) and a clamping bolt (3) that is provided with through hole (43); The through hole of described compact heap (43) both sides are respectively equipped with first flange (41) and second flange (42), and described first flange (41) is resisted against on the end face of cylinder head (2), and described second flange (42) stretches in the groove of oil sprayer (1); Described clamping bolt (3) passes described through hole (43) and is threaded with cylinder head (2), and it is characterized in that: the through hole of described compact heap (43) is provided with the diameter of thread of the diameter of internal thread and described internal thread greater than described clamping bolt (3).
2, the hold down gag of engine fuel injector as claimed in claim 1 is characterized in that: the length of the internal thread of the described through hole (43) that is arranged at compact heap is through whole through hole (43).
