Abstract
The utility model relates to a structure for preventing oil pipe joints from tripping at high pressure. The periphery of the sleeved part of the nozzle tip pipe is provided with a plurality of mating surfaces to form a polygon pressing rings. A feed nozzle tip is fixedly sleeved on the shrinkage pipe part of the periphery to apply strong force to bitingly clamp, and the feed nozzle tip and the plurality of mating surfaces of the sleeved part of the nozzle tip pipe are combined as a whole. By the polygonal mating surfaces and the shrinkage pipe part of the periphery of the sleeved feed nozzle tip, the nozzle tip pipe is not rotated to loose at the time of bearing high voltage.
Description
A kind of structure of unscrewing when oil connection bears high pressure of preventing, relating in particular to a kind of draw portion with the portion that is nested that increases the oil nozzle pipe and oil nozzle fixed cover nibbles in brute force and contacts the clamping area when pressing from both sides, it is loosening to prevent that oil nozzle pipe and oil nozzle pipe fixed cover from rotating, and guarantees the safe handling state of high-pressure oil pipe joint.
General high oil pressure pipe piecing devices, please cooperate consult shown in Figure 1: the three-dimensional exploded view that is traditional joint.Its structure mainly by: a pipe joint (1), a screw connecting sheath (2) and oil pipe fixed cover (a 3) suit combine; Wherein: screw connecting sheath (2) directly is set in the pipe joint (1), be provided with one at aforementioned tube joint (1) outer rim place and nibble embedding portion (1A), directly be placed in another oil pipe fixed cover (3), necking section (3A) on oil pipe fixed cover (3) imposes the folder effect of nibbling of brute force, makes the embedding portion of nibbling (1A) of pipe joint (1) and the necking section (3A) of oil pipe fixed cover (3) be the engages fixed state.
But above-mentioned traditional high oil pressure pipe piecing devices when offering device and make the oil pressure pipe joint and use, have the problem that following one critical defect and the utmost point treat actively to overcome solution at least:
Above-mentioned traditional pipe joint; with the embedding portion of nibbling of its outer rim circle shape and the necking section of oil pipe fixed cover outside; add brute force nibble the folder and fixedly become one; this structure is because the embedding portion of nibbling of circle shape; when being subjected to the stress of high oil pressure; usually the slippage rotation phenomenon can take place, very cause the possibility that gets loose and separate, may cause mutual major injury to device and personnel.
Therefore, the present utility model people is with the practice manufacturing of being engaged in high Oil-pressure joint, the accumulation of knowhow, research and develop into a kind of structure-improved of unscrewing when oil connection bears high pressure of preventing, help at present breakthrough and progress about automatic control industry.
Main purpose of the present utility model: the peripheral region that provides a kind of portion that is nested at the oil nozzle pipe, grind a plurality of joggle(d) joint faces that are equipped with, draw portion for another oil nozzle fixed cover, when imposing brute force engagement folder, have preferable contact lifting surface area and nibble the folder effect, reach tight engagement the effect of setting, prevent that oil nozzle pipe and oil nozzle pipe fixed cover from rotating effect loosening and safe handling.
Fig. 1 is the three-dimensional exploded view of traditional oil connection.
Fig. 2 is the three-dimensional exploded view of the utility model oil connection.
The function and benefit of understanding structure content of the present utility model in depth and can reach for those skilled in the art is easy to, now enumerate detailed introduction of a specific embodiment and conjunction with figs. and be described as follows:
A kind of structure-improved of rotating when oil connection bears high pressure of preventing please cooperate and consult shown in Figure 2ly, is three-dimensional exploded view of the present utility model, and its structure mainly is:
Oil nozzle pipe (10), it is an adapter shape that connects, the mouth of pipe is opening-like, pipe shaft outer rim appropriate position is installed with the portion (11) that is nested, it is characterized in that: the peripheral region of this portion that is nested (11), be equipped with a plurality of joggle(d) joint faces (12) that grind, to form a portion that is nested (11) with a plurality of edges shape;
One clutch collar (20), inboard contain and are provided with a thread section, are inserted in wherein by the below of above-mentioned oil nozzle pipe (10), can be screwed together in the Oil-pressure joint of arbitrary device by free pivot knot;
One oil nozzle fixed cover (30) with oil nozzle pipe (10) fit, and is provided with a draw portion (31) in the appropriate position, apply brute force for it and nibble folder, the three is nested becomes one.
Above-mentioned the utility model that structure assembled by each element, a kind of structure-improved that prevents to execute when oil connection from bearing high pressure pine, it is characterized in that, a plurality of joggle(d) joint faces (12) on the portion that is nested (11) periphery of oil nozzle pipe (10), just for the draw portion (31) of another oil nozzle fixed cover (30) when imposing brute force and nibble folder, increase the lifting surface area that contacts clamping each other between the two, reach tight engagement and set effect, can prevent the portion that is nested (11) and the draw portion (31) of oil nozzle pipe (10) and oil nozzle pipe fixed cover (30), bearing for a long time under the high pressure conditions, rotate the loosening danger that gets loose and separate that very causes, guarantee operator's life safety.
Comprehensively above-mentioned, a kind of structure-improved of unscrewing when oil connection bears high pressure of preventing, at the high oil pressure pipe joint of tradition bear for a long time high oil pressure into and out of the thrust influence, regular meeting causes that the oil pressure pipe joint produces that the turn pine changes both deposits drawback, the improvement of innovating; Simultaneously, the inventor thinks repeatedly and actual fabrication, use after, verifiedly fully can reach model utility institute not function and benefit in advance, that is solve the safety problem of traditional product at all.
