model utility content
The utility model has overcome the deficiencies in the prior art, and a kind of oil pipe mouth of pipe blocking device is provided, and has solved blocking device poor practicability in the past, awkward problem.
For solving above-mentioned technical problem, the utility model is by the following technical solutions: a kind of oil pipe mouth of pipe blocking device, comprise seal closure and seal closure fixing device, seal closure is hollow hemisphere shape, described seal closure internal cavities is sealed chamber, described seal closure fixing device comprises right angle connecting rod, connecting rod one end, right angle is connected with oil pipe clamping cover, the described right angle connecting rod the other end is connected with inner screw sheath, inner screw sheath screw-internal thread fit has adjustable lever, and knob is set in adjustable lever one end and the adjustable lever the other end withstands on seal closure outer peripheral surface middle part.
Described oil pipe clamping cover comprises two involutory annular clamps, and two described annular clamp one end are by the rotating connection of rotating shaft, and two described annular clamp the other ends arrange connecting head, is provided with through hole on connecting head.
Described two annular clamp inner side surfaces are provided with anti-slip tank.
Described sealed chamber inside is filled with the sealing gasket mating with sealed chamber profile.
On described knob, be radially provided with through hole.
Compared with prior art, the beneficial effects of the utility model are: the oil pipe mouth of pipe blocking device of the utility model design, and simple in structure, reasonable in design, good sealing effect, and easy to use, quick, be easy to carry, can be applicable to the oil pipe mouth of pipe shutoff of multiple diameter, practical.
Accompanying drawing explanation
Below in conjunction with the drawings and specific embodiments, the utility model is described in further detail.
Fig. 1 is structural representation of the present utility model.
Label in figure is: 1, knob; 2, inner screw sheath; 3, adjustable lever; 4, seal closure; 5, sealed chamber; 6, right angle connecting rod; 7, annular clamp; 8, connecting head; 9, anti-slip tank; 10, rotating shaft.
Embodiment
Below in conjunction with accompanying drawing, the utility model is further described.Mode of execution of the present utility model includes but not limited to the following example.
Embodiment 1
A kind of oil pipe mouth of pipe blocking device as shown in Figure 1, comprise seal closure 4 and seal closure fixing device, seal closure 4 is hollow hemisphere shape, described seal closure 4 internal cavities are sealed chamber 5, described seal closure fixing device comprises right angle connecting rod 6, connecting rod 6 one end in right angle are connected with oil pipe clamping cover, described right angle connecting rod 6 the other ends are connected with inner screw sheath 2, inner screw sheath 2 screw-internal thread fit have adjustable lever 3, and knob 1 is set in adjustable lever 3 one end and adjustable lever 3 the other ends withstand on seal closure 4 outer peripheral surface middle parts.
When the present embodiment is used, first oil pipe clamping cover is clamped on to oil pipe outer end, the corresponding oil pipe port of seal closure 4 is arranged, by screwing adjustable lever 3, seal closure 4 is held out against at oil pipe port, can reach oil pipe shutoff, prevent that inner unrecovered oil or error from opening and causing Oil spills; The adjustable lever 3 of the present embodiment arranges over against seal closure 4, seal closure 4 evenly can be held out against, and makes seal closure 4 stressed evenly, seals more thorough; At seal closure 4 outer peripheral surface middle parts, be provided with adjustable lever 3 positioning sheaths, can guarantee that adjustable lever 3 seal closure 4 when holding out against is stable, firm; The said structure of the present embodiment design is not only simple in structure, carrying and easy to use, and seal closure 4 directly covers on oil pipe port, and sealing facilitates, effective, can also be applicable to the oil pipe port shutoff of multiple diameter, practical.
Embodiment 2
The present embodiment has been done following optimization on embodiment 1 basis: described oil pipe clamping cover comprises two involutory annular clamps 7, two described annular clamp 7 one end are by the rotating connection of rotating shaft 10, and two described annular clamp 7 the other ends arrange connecting head 8, on connecting head 8, are provided with through hole.
In this enforcement, two annular clamps 7 mate with oil pipe external diameter, until needs, by two, annular clamp 7 is enclosed within oil pipe outside after within 10 minutes around the shaft, opening fixedly time, and by bolt, coordinate with the through hole of connecting head 8 after being combined, thereby two annular clamps 7 are clamped on to oil pipe outside, right angle connecting rod 6 is played a supporting role, guarantee adjustable lever 3 top tight sealing covers.
Further, described two annular clamp 7 inner side surfaces are provided with anti-slip tank 9.In order to strengthen the snap action of annular clamp 7, prevent that seal closure 4 annular clamp 7 when compressing is axially displaced along oil pipe, affect sealing effect, therefore at two annular clamp 7 inner side surfaces, anti-slip tank 9 is all set, the frictional force that strengthens annular clamp 7 and oil pipe by anti-slip tank 9, plays good skidproof effect.
Embodiment 3
The present embodiment has increased following structure on embodiment 1 or embodiment's 2 basis, is specially: described sealed chamber 5 inside are filled with the sealing gasket mating with sealed chamber 5 profiles.
In the present embodiment, for enhanced leaktightness cover 4 sealing effects, prevent seal leakage, in Te sealed chamber 5, add sealing gasket, seal closure 4 is when compressing oil pipe port, thereby sealing gasket is out of shape oil pipe port sealing under power effect, good sealing effect, and also can reduce the loss of seal closure 4, prevent that seal closure 4 and oil pipe port from directly contacting compression and damaging, Security improves.
Embodiment 4
The present embodiment has been done following optimization on above-mentioned arbitrary embodiment's basis, is specially: on described knob 1, be radially provided with through hole.
Originally be implemented in while regulating adjustable lever 3 top tight sealing cover 4, because needs reach good sealing effect, adjustable lever 3 need can by seal closure 4 pressing squares, and the inconvenience of not only exerting all one's strength when using knob 1 to screw, and impacting force is inadequate, not only increased use difficulty, and comparatively require great effort, therefore through hole is radially set on knob 1, when when screwing adjustable lever 3, resistance greatly or compression is firm not, can use long straight-bar through through hole, staff grasps straight-bar two ends and can easily rotate, time saving and energy saving, and for less place, some spaces, when being difficult for exerting all one's strength, hand also can adopt straight-bar to screw, very convenient.
Be as mentioned above embodiment of the present utility model.The utility model is not limited to above-mentioned mode of execution, and anyone should learn the structural change of making under enlightenment of the present utility model, every with the utlity model has identical or close technological scheme, within all falling into protection domain of the present utility model.
