Description

It is a kind of from limitation locking hinge and its shelter door

Technical field

A kind of hinge is the utility model is related to, more particularly to it is a kind of from limitation locking hinge and its shelter door.

Background technology

Opening door hinge common at present, without limitation locking function, it is real that limiter need to be installed additional on door-plate and doorframe Existing limiting locking, has the adjustable advantage of spacing angle.

But the hinge of such a structure and spacing combination have the following disadvantages：

1st, door is opened to after opening angle, it is necessary to the locking nut operated on limiter realizes limiting locking, cumbersome.

2nd, because hinge does not possess limiting locking function in itself, finished parts expense and dress are added simultaneously when increasing stopping means With man-hour, processing and fabricating cost increases.

3rd, because adding limiter this mechanical mechanism, the trouble point increase of product, reliability decreases.

Utility model content

In order to solve the problems, such as in background technology, the utility model provide it is a kind of simple in construction and collect open and close function and The shelter door from limitation locking hinge and its using the hinge of limit function one.

Concrete technical scheme of the present utility model is：

The utility model provides a kind of from limitation locking hinge, including two flaps and bearing pin；Two flaps lead to Cross hinge；It is characterized in that：Wherein, a flap is provided with 2N the first recesses and N number of close to the position of pin joint First is raised, and it is convex that another flap is provided with the 2N individual second being adapted with the 2N the first recesses close to the position of pin joint N number of second recess for rising and being adapted with N number of first projection；N≥1.

Above-mentioned first projection or the second projection are being provided with ball spring lock pin on flap direction of rotation；Phase Answer, second projection or the first projection offer aperture on the position corresponding with the ball spring lock pin.

Above-mentioned hinge also includes split pin；Bearing pin is fixed on flap by the split pin.

Mounting hole is offered on above-mentioned flap, mounting hole is strip hole.

Lubrication groove, pin roll end face installation grease zerk are offered on above-mentioned bearing pin.

Above-mentioned ball spring lock pin is connected with the first projection or the second raised thread.

Above-mentioned first recess and the first projection are inclined-plane.

It is flexible contact between above-mentioned first projection and the second recess and the first recess and the second projection.

It is a kind of using described in claim 1-8 from the shelter door of limitation locking hinge, including movable doorboard, doorframe and peace Hinge between movable doorboard and doorframe.

The utility model has the advantages that：

1st, the utility model is using raised and recesses fit and ball spring lock pin, realizes collection conventional hinge and spacing In one, door is opened to after spacing angle and limitation locking can be achieved the keying limitation locking function of device, simple and convenient.

2nd, after installing the patented product, without installing single limiter, process and assemble cost reduces, and reliability improves.

3rd, the hinge is provided with adjustable strip hole, the adjustment of hinge pin axiality, assembling when being easy to the multiple hinges to install Good manufacturability.

4th, it is that flexibility connects between the first projection and the second recess and the first recess and the second projection of the present utility model Touch, avoid impact of the opening-closing process to flap, add the service life of locking hinge.

Brief description of the drawings

Fig. 1 is the structure diagram of the utility model open mode；

Fig. 2 is the structure diagram of the utility model closure state.

Reference is as follows：

1- flaps, 2- bearing pins, 3- ball springs lock pin, the recesses of 4- first, 5- first are raised, 6- second is raised, 7- the Two recesses, 8- positioning aperture, 9- split pins, 10- mounting holes.

Embodiment

In conjunction with structural representation Fig. 1 and 2, the structure, annexation and position relationship of product are described in detail.

The utility model uses a kind of from limitation locking hinge, including two flaps 1 and bearing pin 2；Two hinges Plate 1 is be hinged by bearing pin 2；Wherein, a flap 1 is provided with 2N the first recesses 4 and N number of first close to the position of pin joint Projection 5, it is raised that another flap is provided with 2N second be adapted with the 2N the first recesses 4 close to the position of pin joint 6 and N number of second recess 7 for being adapted with N number of first projection 5；N≥1；Preferably, wherein, the first recess 4 and the second projection 6 Inclined-plane is used, such limit effect is more preferably.

In order that it is spacing after locking, the utility model first projection 5 or second projection 6 perpendicular to articulated slab Ball spring lock pin 3 is installed on the direction of 1 rotation；Second projection 6 or first projection 5 with the ball spring lock pin phase Positioning aperture 8 is offered on corresponding position.

It should be noted that the bearing pin 2 of the locking hinge is fixed on flap 1 by split pin 9.Except above-mentioned side Formula, bearing pin 2 can also use expansion riveting pin shaft end head mode to fix with the fixation of flap, to replace existing split pin fixed solution.

The adjustment of hinge pin axiality when being installed for the ease of multiple hinges, offer on the good flap of assembly process process Mounting hole 10, mounting hole are strip hole.

In order that hinge rotates flexibly, lubrication groove, pin roll end face installation grease zerk are offered on bearing pin.

In order to prevent ball spring lock pin 3 from coming off, ball spring lock pin 3 is connected with the first projection or the second raised thread.

In order to avoid impact of the opening-closing process to flap, add the service life of locking hinge, the first projection 5 with It is flexible contact between second recess 7 and the first recess 4 and the second projection 6.

It is a kind of using the above-mentioned shelter door from limitation locking hinge, including movable doorboard, doorframe and installed in dodge gate It is above-mentioned from limitation locking hinge between plate and doorframe.

The operation principle or working method of product.

The utility model mainly connects two flaps 1 using bearing pin 2, and one of flap is fixed with doorframe, another Individual flap 1 is fixed with door-plate, by rotation of the flap 1 around bearing pin 2 door-plate can be driven to rotate, on movable doorboard Flap 1 touches two ramp projections on the flap on doorframe by two ramp projections thereon after overturning Realize it is spacing, while spacing, by the ball spring bearing pin 3 that is separately positioned on two flaps and positioning aperture clamping, Locking is realized, so as to realize from limitation locking function.
