The purpose of this utility model can also further realize by following technical measures.
Aforesaid a kind of limit hinge, the lower end of wherein said movable bolt are spherical arc surface.
Aforesaid a kind of limit hinge, wherein said lockplate are provided with the locating hole with the spherical arc surface coupling in described movable bolt lower end; The center line of described locating hole and the center line of described movable bolt are that symmetrical centre is symmetrical with the center line of joint pin, described lockplate is provided with guiding surface towards joint pin one side, and the upper side of described lockplate arrives the distance D of limit hinge upside less than spherical circular arc summit, movable bolt lower end to the distance C of limit hinge upside.
Several oilholes radially that aforesaid a kind of limit hinge, wherein said joint pin are provided with the axial lubrication hole and communicate with it, described hinge axis both sides are provided with oil groove.
Aforesaid a kind of limit hinge, the material of wherein said packing ring are nonmetallic polytetrafluoroethylene (PTFE).
Limit function and hinge function after the utility model Ji Men opens are integrated, and the location is accurately reliable, and has auto-lock function; The utility model is easy and simple to handle.Can open fast, close car door, the utility model is easy to assembly, saves material, low cost of manufacture, good reliability, good looking appearance, is to prevent that car door from opening the reliable Hardware fitting that freely rotate the back.
Advantage of the present utility model and characteristics will illustrate by the non-limitative illustration of following preferred embodiment and explain that these embodiment only provide as an example with reference to accompanying drawing.
Description of drawings
Fig. 1 is a structural representation of the present utility model;
Fig. 2 is the vertical view of Fig. 1;
Fig. 3 is a joint pin full sectional view of the present utility model.
The specific embodiment
The utility model is described in further detail below in conjunction with drawings and Examples.
As shown in Figure 1 and Figure 2, the utility model comprises hinge plate A1, hinge plate B2, joint pin 3, packing ring 4, lock 5; The end of hinge plate A1, hinge plate B2 is respectively equipped with several profile of tooth hinged blocks 12,22, described profile of tooth hinged block 12,22 interlocks each other, be provided with 6 packing rings 4 between the profile of tooth hinged block 12,22, described packing ring 4 adopts nonmetallic polytetrafluoroethylmaterial material to make, after being installed, packing ring 4 avoided directly contact friction between the tooth profile metal hinged block 12,22, make the rotation of hinge more flexible, it is permanent also to have avoided using, because wearing and tearing cause the gap to be strengthened, cause the student to hang down and be difficult to close between the tooth profile metal hinged block 12,22.The profile of tooth hinged block 12,22 of hinge plate A1 and hinge plate B2 is hinged by joint pin 3, and the other end of hinge plate A1, hinge plate B2 is respectively equipped with several installing holes 11,21, can respectively hinge plate A1, hinge plate B2 be separately fixed on door and the doorframe with securing member.
Lock 5 comprises movable bolt 51, stage clip 52, locking cover 53, stop nut 54, lock bearing support 55, lockplate 56; Lock 5 is arranged on the both sides of joint pin 3, and a side is a lock bearing support 55, and opposite side is a lockplate 56.Locking cover 53 passes the installing hole up and down of lock bearing support 55, and with locking cover shoulder 531 location, fixedly connected with locking cover 53 lower ends by lock nut 54 in its lower end, and like this, locking cover 53 just is axially fixed in the lock bearing support 55.Movable bolt 51 is arranged in the locking cover 53, and stage clip 52 is arranged between movable bolt 51 and the locking cover 53, and for the ease of stage clip 52 is installed, the movable bolt 51 of present embodiment is divided into head 511 and bar portion 512, between the two by being threaded.For the ease of combining, throw off with lockplate 56, spherical arc surface is made in the lower end of movable bolt 51.
As shown in Figure 3, for fear of joint pin 3 because of the long-term exposed corrosion that causes outside, catching phenomenon when causing the open and close door, be provided with the installation screwed hole of lubricating cup 6 in the upper end of joint pin 3, radially oilhole 33 of axial lubrication hole 32, communicate with axial lubrication hole 32 6 is set respectively in the joint pin 3, for the ease of storing lubrication oil, joint pin 3 both sides also are provided with oil groove 31.
Door open limit schematic diagram after the utility model shown in Figure 2 is installed, chain-dotted line partly is in spacing state for opening α angle rear cargo door, vertical double dot dash line side is a mounting plane of the present utility model, with the unlatching that realizes car door, close, helps the transportation and the loading and unloading of van.
In the time of need opening the door, car door is applied the moment of opening the door, the utility model drives car door and counterclockwise rotates around joint pin 3, because the spherical arc surface in movable bolt 51 lower ends is lower than the upper side of lockplate 56, spherical arc surface is the guiding surface 562 of contact lockplate 56 earlier, the promotion that is subjected to guiding surface 562 makes movable bolt 51 overcome the elastic force of stage clip 52 and rises, along with further opening of car door is big, the spherical arc surface in movable bolt 51 lower ends further rises to the upper side of lockplate 56, under the effect of the elastic force of stage clip 52, the spherical arc surface in movable bolt 51 lower ends is dropped in the locating hole 561 of lockplate 56, car door locking is in the scope of opening the α degree, and the α angle of present embodiment is greater than 90 °.
Need at closing time, need elder generation that the movable bolt 51 of lock 5 is applied an axial force that makes progress gently, the elastic force that movable bolt 51 overcomes stage clip 52 moves to locking cover 53 tops, when the spherical arc surface in movable bolt 51 lower ends goes out of lock the locating hole 561 of plate 56, can unlock.Can adorn 2 or 3 the utility model according to car door size and weight, during installation, the movable bolt 51 of the lock 5 of each hinge, the locating hole 561 of lockplate 56 must be respectively on same axis.
The utility model was done preservative treatment after both can having adopted common iron to make, and also can adopt stainless steel material to make.The utility model shown in Figure 2 is the R.H.flapped door hinge, at this moment, and lock 5 motion and lockplate 56 is static; The utility model also can be used as the L.H.flapped door hinge, at this moment, and static and lockplate 56 motions of lock 5.
In addition to the implementation, the utility model can also have other embodiments, and all employings are equal to the technical scheme of replacement or equivalent transformation formation, all drop in the protection domain of the utility model requirement.
