Abstract
The invention relates to a locking mechanism which comprises a fixed lug 1, a rocker arm 2, a limiting column 3 on the rocker arm, and a limiting piece 4, wherein the rocker arm 2 is mounted on the fixed lug 1 in a rotating manner; one end of the limiting piece 4 is mounted on the fixed lug 1 in the rotating manner; the limiting column 3 is mounted on the rocker arm 2; the limiting piece 4 is mounted on the limiting column 3, and moves along with the limiting column 3. According to the mechanism, no unnecessary operation is required in an opening locking process, and a cabin door can be automatically locked when being maximally opened; few parts are required, and only the limiting column and the limiting piece are added on the basis of an original structure, so that the mechanism is simple in structure and light in weight, and weight loss caused by unnecessary functions can be reduced to a great extent; the structure is purely mechanical, and only mechanical connection and movement fixation are adopted, so that the mechanism is low in failure rate and reliable in running, and servicing and maintenance flows are reduced.
Description
Technical field
The present invention relates to the spacing and locking mechanism after a kind of locking mechanism, especially hatch door unlatching.
Background technology
Hatch door is the important component part of modern machinery and equipment, and the passage that carry personnel's turnover and working service etc. is opened
The effect of closing.Using frequent, the convenience to operating requires very high.Hook or pneumatic spring etc. are used mostly now to cabin
Position after door is opened carries out limiting and locked, the shortcomings of this mode has complex operation, construction weight big, high cost.And
And do not possess error-preventive design, once forget the generation of situations such as locked situation easily causes the damage of hatch door.
The content of the invention
To solve the spacing and locked defect after existing hatch door is opened and deficiency, problem to be solved by this invention is to carry
For a kind of spacing locking mechanism of hatch door simple to operate, lightweight, with error protection.
To solve the problems, such as the spacing locking mechanism of existing hatch door, the technical solution used in the present invention is：A kind of hatch door
Limited post 3 and banking stop 4 on spacing locking mechanism, including fixed ear base 1, rocking arm 2, rocking arm；Rocking arm 2 is rotatably pacified
It is mounted on fixed ear base 1, the one end of banking stop 4 is rotatably arranged on fixed ear base 1, and limited post 3 is arranged on rocking arm 2, limit
Bit slice 4 is arranged on limited post 3, follows limited post 3 to move.
Used as the spacing locked improvement of the present invention, banking stop has guide rail 41 and stopper slot 42, between guide rail and stopper slot
It is provided with raised 43.
Raised 43 directions are towards guide rail 41.
The line of the center of stopper slot 42 and the spindle central of banking stop 4 is little with raised 43 angles near one side of stopper slot 42
In 90 °.
In the normal moving process of hatch door, limited post 3 is moved with rocking arm 2, is moved in banking stop guide rail, drives banking stop
Motion, hatch door is opened to precalculated position, and limited post 3 is entered in the stopper slot of banking stop.Directly close hatch door when, guide rail with it is spacing
Projection between groove can limit the motion of limited post 3, play locked effect.
When hatch door is opened, the limited post on rocking arm drives banking stop motion, spacing during the angle of hatch door unlatching to setting
Stroke of the post in banking stop guide rail reaches the limit of stuck into stopper slot；When closing hatch door, touching banking stop returns limited post
To in banking stop guide rail, hatch door is promoted to close.
Advantageous Effects：This device during unlatching is locked, without the need for nuisance operation, open automatic to most conference by hatch door
It is locked；Part is few, and limited post and banking stop are only increased on original structure, and simple structure is lightweight, can reduce unnecessary with limits
The weight loss that function is caused；Pure mechanic structure, is all fixed by being mechanically connected and moving, and fault rate is low, reliable, subtracts
Few maintaining and maintenance process.

Specific embodiment
The present invention is described in further detail with reference to Figure of description.
Refer to shown in Fig. 1, a kind of spacing locking mechanism of hatch door, it includes spacing on fixed ear base 1, rocking arm 2, rocking arm
Post 3 and banking stop 4；Rocking arm 2 is rotatably arranged on fixed ear base 1, and the one end of banking stop 4 is rotatably arranged on and fixes
In ear mount 1, limited post 3 is arranged on rocking arm 2, and banking stop 4 is arranged on limited post 3, follows limited post 3 to move, and is being used
Cheng Zhong, fixed ear base 1 is fixed on basal body structure, is fixed structure, and the one end of rocking arm 2 is rotatably mounted on fixed ear base 1,
The other end is arranged on hatch door, can be with hatch door folding, and banking stop 4 plays spacing locked effect.
Used as the spacing locked improvement of the present invention, banking stop has guide rail 41 and stopper slot 42, between guide rail and stopper slot
Raised 43 are provided with, limited post 3 is fixed through guide rail 41 with rocking arm 2, when rocking arm 2 is rotated, guide rail of the limited post 3 in banking stop 4
Middle motion, drives banking stop 4 to follow limited post 3 to move, as shown in Figure 2.
Above-mentioned raised 43 direction is defined towards guide rail 41 to hatch door opening angle.
The line of the center of stopper slot 42 and the spindle central of banking stop 4 is little with raised 43 angles near one side of stopper slot 42
In 90 °, make hatch door stuck in fixed position.
When hatch door opens operation, hatch door is opened to defined position, and limited post enters stopper slot, hold-down support, rocking arm, spacing
Piece forms triangle stabilizing mechanism.
Refer to shown in Fig. 2, when rocking arm 2 is opened to precalculated position with hatch door, limited post 3 is transported in the guide rail of banking stop 4
Extreme position is moved, in the stopper slot 42 of banking stop 4, triangle stabilizing mechanism is formed, it is locked, as shown in Figure 1.
During hatch door shutoff operation, hatch door is promoted to opening direction, nudge banking stop 4, return to limited post 3 spacing
In the guide rail 41 of piece 4, hatch door is promoted to close, as shown in Figure 3.
