Description

Taper lock compact form closure

Technical field

The invention belongs to sealing appliance field, more particularly to a kind of taper lock compact form closure, it is applied to different bores The oil tank conveying oil plant of tank mouth.

Background technology

During petroleum transported, to oil truck carry out oil plant add when need by oil filling riser insert tank mouth in, now in order to Ensure that volatile media obtains efficient recovery, it is to avoid environmental pollution, need effectively to seal tank mouth, although presently, there are many Oil tank sealing device is planted, but can only be sealed for the oil tank of a certain specific model or specified caliber, it is impossible to meet various The use of bore oil truck, so causes the problem of following aspect：Poor compatibility, a kind of sealing device can only correspond to a kind of mouth The oil tank in footpath, cannot meet the seal request in pouring process when there is the oil tank of multiple caliber simultaneously；

The content of the invention

For the problems referred to above, the present invention provides a kind of taper lock compact form closure, it is possible to achieve a kind of oil transportation sealing device Meet the use of various different bore oil tanks.

To solve the above problems, the solution of the present invention is：A kind of taper lock compact form closure, including lid, oil filling riser and lock Tight device, wherein, there are pilot hole, movement slots and air vent on described lid；Described oil filling riser is fixed on lid；Described Locking device is arranged on lid, and locking device includes driving means and latch segment.

Preferably, described driving means include air motor, turbine group, universal joint and leading screw, and air motor passes through whirlpool Wheel group and universal joint are connected with leading screw, leading screw connection latch segment.

Preferably, described driving means are the push rod connection latch segment of cylinder or hydraulic cylinder, cylinder or hydraulic cylinder.

Preferably, described driving means are air motor and rack-and-pinion, and air motor connection gear, tooth bar connection are locked Tight block.

Preferably, described latch segment is hook-shaped or claw-like structures, and described latch segment vertical direction section is olive-type.

Preferably, described lid truncated cone-shaped, described pilot hole are on the outside of lid, parallel with lid round platform bus.

Preferably, described lid is soft rubber material, and described movement slots are that insertion pilot hole is flat with frustum cone side Face otch.

Preferably, have latch segment to extract pin, limiting plate and accumulator tank on described lid, described latch segment extract pin with Lid relative position keeps constant, and quantity is consistent with locking device, and described limiting plate is located at lid bottom, near movement slots, , in lid bottom, shape is consistent with latch segment for described accumulator tank.

Preferably, there is anchor point on described latch segment, described locating point position is corresponding with locking pin position.

Preferably, described locking device, pilot hole, movement slots, latch segment extract pin, limiting plate and accumulator tank quantity one Cause, quantity is more than 1.

This using new principle is：

Latch segment in locking device can by driving means in the lid oblique movement, when the tank of cover cap to oil tank After mouthful, latch segment is moved upwards, blocks tank mouth, applies pressure to tank mouth, plays the effect for being sealed in locking, and oil transportation is locked after finishing Tight block is moved downward, and unclamps tank mouth, and lid easily can be extracted.

The present invention is accessible to be had the beneficial effect that：

1. taper lid is adapted to using cooperatively for multiple caliber tank mouth；

2. locking device can apply pressure to tank mouth, play a part of stabilized seal face.

Specific embodiment

With reference to the accompanying drawings and examples, the specific embodiment of the present invention is described in further detail.

As shown in figure 1, a kind of taper lock compact form closure, including lid 1, oil filling riser 2, locking device and air vent 5, lid For truncated cone-shaped, it is inverted and covers in tank mouth 3, oil filling riser 2 is inserted vertically into lid 1.Locking device includes air motor 41, turbine group 42, ten thousand To section 43, leading screw 44 and latch segment 45.Have pilot hole 11 and movement slots 12 on lid 1, leading screw 44 in pilot hole 11, lid 1 It is soft rubber material, movement slots 12 are Plane Notch, are closed at ordinary times, and latch segment 45 is planar as, with the movement slots 12 on lid 1 In same plane, movement slots 12 can be strutted into after movement slots 12 by latch segment 45.

Latch segment is also equipped with lid 1 and extracts pin 13 and limiting plate 14, with 1 geo-stationary of lid, latch segment is extracted Pin 13 moves to the position reached during bottom positioned at latch segment 45, has anchor point extract latch segment on latch segment 45 Pin card 13 enters, and limiting plate 14 is located at 1 bottom of lid, and there be accumulator tank 15 side of movement slots 12,1 bottom of lid.

Operation principle of the present invention is as follows：

When the lid of lid 1 is to tank mouth 3, accumulator tank 15 of the latch segment 45 positioned at position I is after starting air motor 41, pneumatic Motor drives leading screw 44, leading screw 44 to drive latch segment 45 to rotate after rotating by turbine group 42 and universal joint 43, turns to position II, now latch segment extract the anchor point that pin 13 snaps in latch segment 45, latch segment 45 is no longer rotated with leading screw 44, only along leading screw 44 Direction translates up.Movement slots 12 are led into by limiting plate 14 when latch segment 45 is continued up, latch segment 45 is flat, Vertical direction section is olive-type, can be strutted the movement slots 12 on the lid 1 of soft rubber material, as shown in Figure 2.Now lock Block 45 reaches position III, and as shown in Fig. 3 Fig. 4, the position that latch segment 45 is located in movement slots 12 struts, and other positions are in closure Shape, still possesses sealing effectiveness.Latch segment 45 is contacted with tank mouth 3 after continuing up translation, and applies pressure to tank mouth 3, plays lock Tight effect.Latch segment 45 is the hook being bent upwards, and in locking, 45 position of latch segment is less than tank mouth 3,3 height of tank mouth Movement slots 12 are still closed, and do not affect sealing.

After oil plant conveying is finished, air motor 41 is inverted, and latch segment 45 is translated downwards, due to not having after abjection lid 1 The guiding of movement slots 12, latch segment 45 are rotated with leading screw 44 under the drive of leading screw 44, reach stop motion after accumulator tank 15, lid 1 opens and completes an oil plant conveying.
