Abstract

This utility model relates to a kind of fuel tank truck manhole, is specifically related to a kind of clamping hoop type low-loss fuel tank truck manhole.It includes lid, lid, left clip, right clip, flange nut, T-bolt, safety lock, hinge bolt, hex nut, hex bolts, locking nut, seal washer, described lid is coordinated with lid by hex bolts, described safety lock is fixed on lid by latch, safety lock boss is in below lid block, avoid unexpected unlatching, described left and right clip end is fixed on lid by hinges, described T-bolt is fixed in right clip, is coordinated with flange nut by groove outside safety lock.Which overcome conventional manhole's lid efficiency of loading and unloading low; the defect of sealing difference; solve the problem that lid discontinuity exists bending stress; there is efficiency of assembling high; good seal performance, oil product evaporating loss is low, long product lifecycle; take into account the beneficial effects such as protection environment, be particularly suitable for equipping the high leakproofness oil truck of manhole cover.

Description

A kind of clamping hoop type low-loss fuel tank truck manhole

Technical field

This utility model relates to a kind of fuel tank truck manhole, is specifically related to a kind of clamping hoop type low-loss fuel tank truck manhole.

Background technology

The kind of the fuel tank truck manhole that currently there are is a lot, and conventional manhole covers the 6-8 eye bolt that uses more, so One is to cause in use needing multiple bolts, nut dismounting, and the efficiency of loading and unloading is extremely low, and two is that discontinuity exists bending Stress, service life is short, and three is to cause that seal is low, oil loss is higher, damages environment.

Utility model content

This utility model aims to solve the problem that the problems referred to above, it is provided that a kind of clamping hoop type low-loss fuel tank truck manhole, it overcomes Traditional fuel tank truck manhole because using 6-8 eye bolt to cause the efficiency of loading and unloading extremely low, the defect of sealing difference, solve lid and be subject to The uneven problem that there is bending stress of power, its technical scheme used is as follows:

A kind of clamping hoop type low-loss fuel tank truck manhole, including lid, lid, left clip, right clip, flange nut, T-shaped Bolt, safety lock, hinge bolt, hex nut, hex bolts, locking nut, seal washer, described lid (1) passes through hinge Bolt (8) is connected with lid (2), and described hinge bolt (8) coordinates fastening, described seal washer (12) to put with hex nut (9) Putting in the lid (1) sealed groove with lid (2), described safety lock (7) is fixed on lid (1) by latch, and makes safety Lock boss is in below lid block, and described left clip (3) and right clip (4) end are fixed on lid by hex bolts (10) On, hex bolts (10) is locked by described locking nut (11), and described T-bolt (6) is fixed in right clip (4) front end, institute Stating flange nut (5) to be fixed in left clip (3) front end, described T-bolt (6) is by safety lock (7) outside groove and flange Nut (5) is fixed.

On the basis of technique scheme, described left clip (3) and right clip (4) are by single T-bolt (6) and flange Nut (5) fastens, it is achieved high assembling, and described lid (1) and lid (2) are by left clip (3) and the receipts of right clip (4) Compaction forces seals, it is achieved uniform force.

This utility model has the advantage that have efficiency of assembling height, and good seal performance, oil product evaporating loss is low, product Service life is long, takes into account the beneficial effects such as protection environment, is particularly suitable for equipping the high leakproofness oil truck of manhole cover.

Symbol description

1. lid, 2. lid, the most left clip, the rightest clip, 5. flange nut, 6.T type bolt, 7. safety lock, 8. hinge Bolt, 9. hex nut, 10. hex bolts, 11. locking nuts, 12. seal washers.

Detailed description of the invention

The utility model is described in further detail with example below in conjunction with the accompanying drawings:

As shown in Figure 1, Figure 2, Figure 3, Figure 4, a kind of clamping hoop type low-loss fuel tank truck manhole of the present utility model, described lid Son 1 is connected with lid 2 by hinge bolt 8, and described hinge bolt 8 coordinates fastening with hex nut 9, and described seal washer 12 is put Putting in the sealed groove of lid 1 and lid 2, described safety lock 7 is fixed on lid 1 by latch, and makes at safety lock boss Below lid block, described left clip 3 and right clip 4 end are fixed on lid by hex bolts 10, described locking screw Hex bolts 10 is locked by female 11, and described T-bolt 6 is fixed in right clip 4 front end, and described flange nut 5 is fixed on left card Binding round in 3 front ends, described T-bolt 6 is fixed with flange nut 5 by groove outside safety lock 7.

Preferably, described left clip 3 and right clip 4 are fastened by single T-bolt 6 and flange nut 5, it is achieved high Assembling, described lid 1 is sealed by the pressure that tightens up of left clip 3 and right clip 4 with lid 2, it is achieved uniform force.

In use, when carrying out opening manhole cover, using specialized nut rifle to turn on flange nut 5, left clip 3 is along with method Blue nut 5 to anticlockwise, extracts T-bolt 6 out, by clip 4 along with T-bolt 6 around hex bolts 10 to the right around hex bolts 10 Rotating, release clip is to lid 1 and the seal pressure of lid 2, with carrying safety lock 7 on hand, makes safety lock 7 lower end boss avoid lid Body 2 block, is lifted up lid 1 handle, and lid 1 rotates around hinge bolt 8, when carrying out closing manhole cover, checks sealing gasket Whether circle 12 is placed in lid 2 sealed groove, transfers lid 1 and seals with lid 2, spin safe lock 7 restriction lid 1 and lid The switch of 2, rotary flange nut 5 and T-bolt 6 so that it is cooperate, left clip 3 and right clip 4 are to lid 1 and lid 2 Carry out pressure sealing.

The most by way of example this utility model is illustrated, but this utility model is not limited to above-mentioned being embodied as Example, all any changes done based on this utility model or modification belong to the scope that this utility model is claimed.
