Description
Technical field
This utility model relates to a kind of linkage with limit function, belongs to technical field of engineering machinery.
Background technology
It is known that be fitted with hood above most of engineering mechanical devices, for example, Engine Casing, radiator hood,
Main pump room hoods etc., on the one hand the existence of hood is played the effect of decoration, is on the other hand facilitated the ordinary maintenance of equipment to maintain.But
It is the problem that hood is opened that there is also while being equipped with hood, because being all to be fixed by hinge and framework above hood, how
Allow the realization that hood can be convenient open and close, and facilitate the maintenance of machinery equipment and ensure certain service clearance,
It it is the engineering machinery designer content that needs that when doing product design emphasis considers.
At present, on market, on engineering mechanical device, hood hinge type is more, mainly can be classified as two big classes, and the first kind is common
Linkage, function only as hood fix and ensure open effect, it is impossible to realize limit function；Equations of The Second Kind is that hood is being opened
After opening maximum position, can be spacing by it by strut.Wherein, Equations of The Second Kind Application comparison is many, but with limit function
How position-limit mechanism can be done simple and practical of hinge and to be not take up larger space be a problem demanding prompt solution.
Summary of the invention
The problem existed for above-mentioned prior art, this utility model provides a kind of linkage with limit function, Ke Yishi

To achieve these goals, a kind of linkage with limit function that this utility model uses, including main hinge, pair
Hinge, hinge pin and limited support assembly, described main hinge and secondary hinge are connected by hinge pin, hinge pin and main hinge
It is welded and fixed between chain；Described limited support assembly is arranged on main hinge, the top of secondary hinge, one end of limited support assembly with
Main hinge is fixing to be connected, the other end and secondary chain connection；Secondary hinge can slide along limited support assembly, and can be positioned.
Described limited support assembly includes limited support and spacing back-up ring, and limited support has chute and round tube hole, spacing back-up ring
At the round tube hole being welded on limited support；The round tube hole of limited support passes together with spacing back-up ring and is welded on the pin above main hinge
Axle II, and carry out spacing with split pin through bearing pin II；Chute on limited support passes bolt I fixing above secondary hinge, spiral shell
Bolt I can slide relatively along chute, rotates wing nut I and realize locking positioning when sliding into desired location.
Preferably, a packing ring is installed between described wing nut I and limited support.
Preferably, described bolt I is from bottom to top through the through hole on secondary hinge, and is positioned by wing nut II and washer locking.
Preferably, between described limited support and main hinge, accompany cushion block, in order to ensure limited support energy horizontal positioned.
Compared with prior art, this utility model passes through simple position-limit mechanism, realizes the spacing of hinge with less space structure
Function, design cost is low, time saving and energy saving, practical, and effect is obvious.

Detailed description of the invention
The utility model is described in further detail below in conjunction with the accompanying drawings.
As shown in Figures 1 to 4, a kind of linkage with limit function, including main hinge 1, secondary hinge 2, hinge pin
9 and limited support assembly 4, described main hinge 1 and secondary hinge 2 are connected by hinge pin 9, hinge pin 9 and main hinge 1
Between be welded and fixed；Described limited support assembly 4 is arranged on main hinge 1, the top of secondary hinge 2, limited support assembly 4
One end is fixing with main hinge 1 to be connected, and the other end is connected with secondary hinge 2；Secondary hinge 2 can slide along limited support assembly 4,
And can be positioned.
Described limited support assembly 4 includes limited support 41 and spacing back-up ring 42, and limited support 41 has chute and round tube hole,
Spacing back-up ring 42 is welded at the round tube hole on limited support 41；The round tube hole of limited support 41 passes together with spacing back-up ring 42
It is welded on main hinge 1 bearing pin II10 above, and carries out spacing with split pin 11 through bearing pin II10；On limited support 41
Chute can slide along chute relatively through secondary hinge 2 the most fixing bolt I7, bolt I7, rotates when sliding into desired location
Wing nut I6 realizes locking positioning.
Preferably, a packing ring 3 can be installed between described wing nut I6 and limited support 41.
Preferably, described bolt I7 is from bottom to top through the through hole on secondary hinge 2, and is positioned by nut 13 and washer locking.
Preferably, between described limited support 41 and main hinge 1, accompany cushion block 12, in order to ensure that limited support 41 can level be put
Put.
Preferably, described secondary hinge 2 also can be provided with bearing pin I5, bearing pin I5 and be positioned at the outside of bolt I7, bearing pin I5 sets up
Double insurance effect can be played.
During use, main hinge 1 is fixed on above hood by available bolt II8, and is fixed on above hood framework by pair hinge 2.
Assume to proceed by operation when hood is in and opens now, first wing nut I6 unclamped when hood closed by needs,
Then limited support assembly 4 is lifted up, until exceeding bearing pin I5 upper surface bottom limited support 41, as shown in Figure 2.
Then pushing inward hood, secondary hinge 2 will rotate along the chute above limited support 41, during this period if it is desired in office
Meaning position stops and keeping this position motionless, only need to be tightened by wing nut I6, only need to be shifted onto by hood as need not location
The end.When hood needs to open down, first pulling hood outwards to open, now secondary hinge 2 is same along spacing
Support 41 upper hopper chute slide, period optional position it can also be made to be locked in a certain position by tightening wing nut I6, as
Need not pull out hood the most always, until limited support 41 chute least significant end contacts with bolt II7, now limited support 41
Least significant end do not contact with bearing pin I5, limited support assembly 4 will be automatically lowered extreme lower position due to gravity as it is shown on figure 3,
The least significant end of limited support 41 just falls between bolt I67 and bearing pin I65, the most all cannot move, and now hood is in
Open position, and limited support 41 greatly is in a locked position, is locked by wing nut I6 simultaneously, plays double insurance
Effect, thus hood is carried out spacing.
Additionally, during processing and manufacturing, main hinge 1 and secondary hinge 2 can use sheet-metal baiting bending to form, limited support 41, limit
Position back-up ring 42 and cushion block 12 all use machine tooling molding, easy, easily manufactured and sound construction of drawing materials.Institute used by mechanism
There are bearing pin, bolt and wing nut all can use state's tender, add versatility and the convenience of whole mechanism.
From said structure, this utility model passes through simple position-limit mechanism, realizes the spacing of hinge with less space structure
Function, design cost is low, time saving and energy saving, practical, and effect is obvious.
