Abstract
The utility model relates to a locking high -pressure oil plug. Oil plug (1) connects soon on oil circuit piece (2), oil plug (1) overcoat is equipped with the fender ring (3) of conflict on oil circuit piece (2), keeps off the fixed setting of ring (3) on oil circuit piece (2), keep off ring (3) including compressing tightly clamp plate (31) on oil plug (1) upper surface, clamp plate (31) lower surface protrusion is provided with bulge loop (32), bulge loop (32) form blockking oil plug (1) side. The utility model discloses a keep off the setting of ring, clamp plate, the clamp plate forms inseparable suppression to the oil plug from upper portion, and the clamp plate is through keeping off inseparable the fixing on the oil circuit piece of ring, therefore its locking effect obtains the strong guarantee, just the utility model discloses set up the bulge loop, setting up of bulge loop has formed blockking the oil plug for the oil plug can not produce lateral movement in the working process.
Description
Technical field
The utility model relates to a kind of locking high pressure oil stopper, and it is mainly used among high-pressure high flux hydraulic power system.
Background technique
In high-pressure high flux hydraulic power system, because system pressure is high, flow large, hydraulic shock power is large, cause the plug cock on manifold block (auxiliary hole plug) easily to loosen, thus produce leakage of oil, this is avoid greatly in hydraulic system; The most complex structure of existing anti-loose structure, easily damages, and needs to be improved further.
Model utility content
The utility model is for above-mentioned defect, and it is simple that object is to provide a kind of structure, has multiple anti-loose structure, thus guarantee the locking high pressure oil stopper of one that plug cock does not in use loosen.
The technical solution adopted in the utility model is for this reason: plug cock of the present utility model (1) is screwed on manifold block (2), and be arranged with the baffle ring (3) of conflicting on manifold block (2) outside described plug cock (1), baffle ring (3) is fixedly installed on manifold block (2); Described baffle ring (3) includes the pressing plate (31) be pressed on plug cock (1) upper surface; Described pressing plate (31) lower surface protrudes and is provided with bulge loop (32), and described bulge loop (32) forms the stop to plug cock (1) side.
Described baffle ring (3) side opening is provided with the through hole (33) of some lateral direction penetratings, and described through hole (33) place is equipped with screw rod (4) and is pushed against the side of plug cock (1).
Described plug cock (1) side is provided with the screw (11) arranged with described screw rod (4) correspondence.
Cushion (5) is set between described bulge loop (32) and plug cock (1).
The utility model has the advantages that: 1) the utility model is by the setting of baffle ring, pressing plate, pressing plate is formed plug cock from top and suppresses closely, and pressing plate is fixed on manifold block closely by baffle ring, therefore its anti-loosing effect obtains strong guarantee, and the utility model arranges bulge loop, the setting of bulge loop defines the stop to plug cock, makes plug cock in working procedure to produce lateral movement;
2) the utility model is further provided with through hole at baffle ring side opening, and be pushed against the side of plug cock by screw rod, such one rotation that can prevent plug cock, two can prevent moving axially of plug cock, three lateral movements that can stop plug cock, therefore further increase anti-loosing effect;
3) screw that the utility model is further arranged in plug cock side and screw rod is corresponding, this avoid the slip between screw rod and plug cock, further increases anti-loosing effect;
4) the utility model arranges cushion between bulge loop and plug cock, due to the existence of cushion, it can be made with plug cock and bulge loop contact more tight, further increase anti-loosing effect.
In sum, the utility model structure is simple, by the reasonable setting to each parts, achieves multiple anti-loosing effect, possesses good using effect.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
1 be plug cock, 2 be manifold block in figure, 3 be baffle ring, 4 be screw rod, 5 for cushion;
11 be screw, 31 be pressing plate, 32 be bulge loop, 33 for through hole.
Embodiment
Plug cock 1 of the present utility model is screwed on manifold block 2, and be arranged with the baffle ring 3 of conflicting on manifold block 2 outside described plug cock 1, baffle ring 3 is tightened on manifold block 2; Described baffle ring 3 includes the pressing plate 31 be pressed on plug cock 1 upper surface; Described pressing plate 31 lower surface protrudes and is provided with bulge loop 32, and described bulge loop 32 forms the stop to plug cock 1 side.
Described baffle ring 3 side opening is provided with the through hole 33 of some lateral direction penetratings, and described through hole 33 place is equipped with screw rod 4 and is pushed against the side of plug cock 1.
Described plug cock 1 side is provided with the screw 11 arranged with described screw rod 4 correspondence.
Between described bulge loop 32 and plug cock 1, cushion 5 is set.
Working procedure of the present utility model is: first screw baffle ring 3, baffle ring 3 is fixed on manifold block 2, and pressing plate 31 is closely conflicted on plug cock 1, then screw rod 4 is passed through hole 33, and be pushed against on the side of plug cock 1 by screw rod by screw 11, thus realize fastening to plug cock 1.
Claims (4)
