Abstract
The utility model provides a sealed lid for aircraft tank oil filler hole, it is including pressing from both sides tight latch segment (9, 12) and control with closing cap (7) axial handle (1) of latch segment action and will seal the lid and connect connecting bolt as an organic whole (3), handle (1) is installed and is connected with connecting bolt (3) in recess (17) on closing cap surface and through round pin spool (2). The utility model discloses make the outstanding oil tank surface of the sealed lid of oil tank oil filler hole few as far as, when refueling, the sealed lid of oil filler hole can convenient and fast ground and the separation of oil filler hole seat, has added the oil back, and the oil filler hole seals and covers the undamaged sealed oil filler hole of ability.
Description
Technical field
This utility model relates to fuel oil box design field, is specifically related to a kind of sealing lid for fuel tanker oil filler.
Background technology
Convenience and the requirement of sealing that lid uses is sealed for meeting fuel tanker oil filler, the oil filler of fuel tank seals lid and is typically threaded connection and seals, it is more that tank filler seals the prominent tank surface of lid, and oiling all must turn on oil filler sealing lid every time, seal lid can not separate with oil filler seat quickly, life-time service can cause thread abrasion, oil filler sealing it cannot be guaranteed that, during turning on, metal and metal friction can produce electrostatic, affect aviation safety.
Summary of the invention
This utility model is for above-mentioned technical problem, a kind of sealing lid for fuel tanker oil filler is proposed, tank filler is made to seal the prominent tank surface of lid the fewest, when refueling, oil filler seals lid and can separate with oil filler seat conveniently and efficiently, after adding oil, oil filler seals the sealing oil filler that lid can be intact.
For achieving the above object, the technical solution adopted in the utility model is: provide a kind of sealing lid for fuel tanker oil filler, including capping, 2nd O RunddichtringO, it is characterized in that: it includes with covering the latch segment of axial grip and to control the handle of described latch segment action and sealing the connecting bolt that lid connects as one, the hole that connecting bolt and the second latch segment connect is square opening, connecting bolt is provided with bearing pin, first pad, first sealing ring, spring, split nut, it is connected with connecting bolt in handle is arranged on the groove of closure surface and by bearing pin.
Further scheme is, above-mentioned handle is right angle trapezoidal shape, and its thickness is more than the distance between bearing pin axle center and described first pad.
This utility model is compressed with oil filler seat by compact heap, so that oil filler seals lid and is connected with oil filler seat, utilize what handle rotation realized oil filler to open with airtight, it is to avoid threaded and seal, handle is arranged in the groove of closure surface, it is achieved oil filler seals lid and casing level.

Detailed description of the invention
Below in conjunction with accompanying drawing, this utility model detailed description of the invention is described in further detail.
As shown in Figure 1, oil filler seals lid makes latch segment enter in fuel tank by the groove on oil filler seat, handle 1 is connected with connecting bolt 3 by latch 2, capping 7 is connected (the first latch segment 9 is connected with the second latch segment 12 by bolt 13 and is fastened with nut 14) by connecting bolt 3 with latch segment 9,12, and fasten with the first self-locking nut 11, centre is provided with spring 8, and handle 1 is arranged in the groove 17 of closure surface.When handle 1 is mentioned, because there are differences between handle thickness and latch junction point distance the first pad 5, the former is 2.55mm, exceeds certain distance (exceeding 1.4mm) than the 1.15mm of the latter, connecting bolt 3 moves toward latch segment 9,12 direction, makes latch segment 9,12 separate with tank internal surface.Handle 1 rotates counterclockwise 90 °, the connecting bolt 3 being attached thereto rotates counterclockwise 90 ° therewith, the hole being connected with the second latch segment 12 due to connecting bolt 3 is square opening, therefore latch segment 9,12 rotates counterclockwise 90 ° the most therewith, now cover 7 upper limit boss 16 and completely disengage from limit point on the first latch segment and contact, handle 1 rotates clockwise 90 °, cover 7 upper limit boss 16 locked limit point complete with on the first latch segment to contact, by lower handle 1, spring 8 compresses, 2nd O RunddichtringO 6 is in close contact with oil filler seat 15, it is achieved seal.
This utility model compresses oil filler seat by latch segment, and the 2nd O RunddichtringO in capping 7 is in close contact with oil filler wall thus realizes sealing；By mentioning handle 1, make latch segment unclamp, by rotary handle 1, make latch segment upper limit position groove turn to fully open or completely enclosed point thus realize opening and sealing of oil filler.
Claims (2)
1. the sealing lid for fuel tanker oil filler, including capping (7), sealing ring (6), it is characterized in that: it includes can be with the latch segment (9 of capping (7) axial grip, 12) and control the handle (1) of described latch segment action and the connecting bolt (3) that connects as one of lid will be sealed, the hole that connecting bolt (3) is connected with latch segment (12) is square opening, connecting bolt (3) is provided with bearing pin (2), pad (5), sealing ring (4), spring (8), nut (14), it is connected with connecting bolt (3) in handle (1) is arranged on the groove (17) of closure surface and by bearing pin (2).
2. as claimed in claim 1 for the sealing lid of fuel tanker oil filler, it is characterised in that: handle (1) is right angle trapezoidal shape, and its thickness is more than the distance between bearing pin axle center and described pad (5).
