Description
Technical field
The utility model relates to dumping car technical field, espespecially a kind of door in door lockset.
Background technology
Common rear board of self-dump truck door in door generally uses the lockset of freight container to fix door in door, although can play certain locking effect, but the severe industrial and mineral using with respect to dumping car, safe reliability is unsatisfactory, due to the enormous impact power of goods to back door, make door in door lockset after using a period of time, be easy to distortion or come off, can not continue to maintain former function, make a big impact to the safe reliability of vehicle.
Utility model content
The purpose of this utility model is to provide a kind of door in door lockset, and it can effectively reduce the lockset damage phenomenon that goods causes the impact of self dumping lorory back door jack, and it is easy to use and reliable, simple in structure, and safety improves greatly.
To achieve these goals, technical solution of the present utility model is: a kind of door in door lockset, comprising the handle being articulated with on door in door, on described handle, be positioned at a left side for itself and door in door pin jointed end, right-hand respectively with first, one end of two pipe links is hinged, described first, the other end of two pipe links is respectively with first, one end of two locking rods is hinged, the other end of described the first locking rod is from top to bottom through being placed through in the first locking seat after the first guiding mechanism being installed on door in door, described the first locking seat is fixed on door in door lower frame, the other end of described the second locking rod is from bottom to top through being placed through in the second locking seat after the second guiding mechanism being installed on door in door, described the second locking seat is fixed on door in door upper ledge, one end of described handle is stuck on stop gear, described stop gear is arranged on door in door.
The utility model door in door lockset, the pin jointed end of wherein said first and second pipe link and handle is symmetricly set in the pin jointed end arranged on left and right sides of handle and door in door.
The utility model door in door lockset, wherein said second a, pipe link lower symmetrical in shape, described second a, locking rod lower symmetrical in shape.
The utility model door in door lockset, wherein said the first guiding mechanism is two upper and lower spaced the first orienting lugs, the rear surface of each the first orienting lug is respectively arranged with the first open slot, described the first locking rod is through two the first open slots, described the second guiding mechanism is two upper and lower spaced the second orienting lugs, the rear surface of each the second orienting lug is respectively arranged with the second open slot, and described the second locking rod is through two the second open slots.
The utility model door in door lockset, wherein said stop gear is a limiting stopper.
Adopt after such scheme, the utility model door in door lockset is articulated with the handle on door in door by setting, be articulated with first on handle, two pipe links, be articulated with first, on two pipe links first, two locking rods, first, two guiding mechanisms and first, two locking seats, when turning handle makes first, two locking rods are inserted in respectively first, in two locking seats, and one end of handle is stuck on stop gear, now the utility model door in door lockset locking, and in the time rotating backward handle, handle departs from stop gear, and the first locking rod departs from the first locking seat, the second locking rod departs from the second locking seat, now the utility model door in door lockset is opened, it is simple in structure, can effectively reduce the lockset damage phenomenon that goods causes the impact of self dumping lorory back door jack, easy to use and reliable, safety improves greatly.
Accompanying drawing explanation
Fig. 1 is the lockup state structural representation of the utility model door in door lockset;
Fig. 2 is the open mode structural representation of the utility model door in door lockset.
The specific embodiment
As shown in Figure 1, the utility model door in door lockset lockup state structural representation, it comprises the handle 2 that is articulated with the horizontal positioned on door in door 1 by bearing pin, and the left and right side who is positioned at itself and door in door 1 pin jointed end on handle 2 is hinged by the upper end of bearing pin and head rod 3 and the lower end of the second pipe link 4 respectively.The pin jointed end of head rod 3, the second pipe link 4 and handle 2 is symmetricly set in the pin jointed end arranged on left and right sides of handle 2 and door in door 1.The upper and lower symmetry of shape of the second pipe link 4 and head rod 3.The lower end of head rod 3 is hinged by the upper end of bearing pin and the first locking rod 5, and the upper end of the second pipe link 4 is hinged by the lower end of bearing pin and the second locking rod 6.The lower symmetry in shape of the second locking rod 6 and the first locking rod 5.The lower end of the first locking rod 5 is from top to bottom through being placed through in the first locking seat 9 after the first guiding mechanism 7 being installed on door in door 1.The first guiding mechanism 7 is two upper and lower spaced the first orienting lugs, the rear surface of each the first orienting lug is respectively arranged with the first open slot (not shown) that connects upper and lower side, the rear surface of two the first orienting lugs is fixed on door in door 1, and the first locking rod 5 is through two the first open slots.The first locking seat 9 is fixed on door in door lower frame 11.The upper end of the second locking rod 6 is from bottom to top through being placed through in the second locking seat 10 after the second guiding mechanism 8 being installed on door in door 1.The second guiding mechanism 8 is two upper and lower spaced the second orienting lugs, the rear surface of each the second orienting lug is respectively arranged with the second open slot (not shown) that connects upper and lower side, the rear surface of two the second orienting lugs is fixed on door in door 1, and the second locking rod 6 is through two the second open slots.The second locking seat 10 is fixed on door in door upper ledge 12.The right-hand member of handle 2 is stuck on stop gear 13.Stop gear 13 is a limiting stopper, and it is fixed on door in door 1, now lockset locking.
