Abstract
The invention relates to an anti-loose high-pressure oil plug. The oil plug (1) is rotatably connected to an oil path block (2), and the oil plug (1) is sleeved with a check ring (3) in contact with the oil path block (2) in an abutting manner; the check ring (3) is fixedly arranged on the oil path block (2) and comprises a pressing plate (31) compressed on the upper surface of the oil plug (1); and a protruding ring (32) is arranged on the lower surface of the pressing plate (31) in a protruding manner, and forms blocking to the side face of the oil plug (1). Through the arrangement of the check ring and the pressing plate, the pressing plate tightly presses the oil plug from the upper portion, and the pressing plate is tightly fixed to the oil path block through the check ring, so that the anti-loose effect is forcefully ensured; and due to the arrangement of the protruding ring, the protruding ring blocks the oil plug, and in the working process, the oil path cannot generate lateral movement.
Description
Technical field
The present invention relates to a kind of locking high pressure oil stopper, 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.
Summary of the invention
The present invention is directed to above-mentioned defect, 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 used in the present invention is for this reason: plug cock of the present invention (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).
Advantage of the present invention is: 1) the present invention 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 present invention 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 present invention 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 present invention 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 present invention 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, structure of the present invention 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 invention.
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 invention 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 invention 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)
