The specific embodiment
Be below specific embodiment of the utility model, now by reference to the accompanying drawings the utility model be described further.
Embodiment 1
As shown in Figures 1 to 4, a kind of engine shroud door is opened position-limit mechanism, and it comprises lock body 2, lock body fixed head 3 and the protecting hood door that is provided with lockhole 1 being used in conjunction with lock; Wherein lock body 2 and lock body fixed head 3 are arranged on one end of protecting hood door 1 hinge; Protecting hood door 1 is arranged on the other end of hinge; Lock body 2 comprises handle 21, fairlead 22, spring 23, plain cushion 24, bullet pad 25 and hold-down nut 26; Fairlead 22 is the little hollow circular cylinder in large one end, internal diameter one end and is fixed on lock body fixed head 3; Handle 21 comprises bar-shaped guide rod 214 and a baffle plate 213; Guide rod 214 one end fixed dams 213, guide rod 214 other ends are provided with screw thread, and fairlead 22 is inserted in the threaded one end of guide rod 214 from the little internal diameter of fairlead 22 one end; Spring 23 is enclosed within on guide rod 214 and is positioned at the large diameter of fairlead 22; Hold-down nut 26 is arranged on guide rod 214 ends of thread; Plain cushion 24 and bullet pad 25 are contained between spring 23 and hold-down nut 26; Under free state, described spring 23 is subject to a little pressure, and spring 23 one end prop up the little internal diameter of fairlead 22, the other end props up plain cushion 24.
Handle 21 one end welding strip limiting plates 212; On limiting plate 212, weld draw ring 211.
When protecting hood door 1 is during in closed condition, the spring 23 in lock body 2 in half compressive state, guarantees that whole lock body 2 each elements are in Pre strained state under the effect of plain cushion 24, bullet pad 25 and hold-down nut 26, prevents vibration; In the time opening protecting hood door 2, protecting hood door 2 is after 180 ° of upsets, the draw ring 211 of lock body 2 passes completely through the lockhole of protecting hood door 2, and now limiting plate 212, also in lockhole, pulls handle 21 until limiting plate 212 exposes lockhole completely with pointing through draw ring 211 vertically upward, in this process, spring 23 further compresses, and produces elastic force, then by handle 21 half-twists, now limiting plate 212 is perpendicular to lockhole, protecting hood door 2 limited plate 212 limiting lockings under the active force of spring 23 like this.
Embodiment 2
As shown in Fig. 3 to Fig. 7, a kind of engine shroud door is opened position-limit mechanism, and it comprises lock body 2, lock body fixed head 3 and the portable plate that is provided with lockhole 11 being used in conjunction with lock; Wherein the structure of lock body 2 is the same with the lock body in embodiment 1; Lock body fixed head 3 is fixed on protecting hood door 1 rotating shaft inner side, lock body 2 and protecting hood door 1 shaft parallel; Protecting hood door 1 inner side is fixed with the portable plate 11 coordinating with lock body 2, and portable plate 11 rotates around protecting hood door 1 rotating shaft; Hold-down nut 26 one end of lock body 2 prop up portable plate 11, and in the time that portable plate 11 is opened with protecting hood door 1, hold-down nut 26 ends embed lockhole 4 under the pressure of spring 23.
When protecting hood door 1 is during in closed condition, on protecting hood door 1 welding the portable plate with lockhole 11 make spring 23 in compressive state, now the threaded one end of guide peg 214 returns in fairlead 22 completely.Open in protecting hood door 1 process, once the lockhole of portable plate 11 is slipped in guide peg 214 terminations, the oppressive force of its end disappears, and under spring 23 effects, guide peg 214 stretches out fairlead 22 again, thereby reaches the object of limiting locking.While again closing protecting hood door 1, only need pull out handle 21, make the threaded termination of guide peg 214 leave portable plate 11 lockholes completely, protecting hood door 1 is again in movable state, thereby reaches the object of closing the door.
