Two-door-linkage structure
Technical field
The invention belongs to the technical field of door, lid opening and closing structure, be specifically related to a kind of two-door-linkage structure.
Background technology
Existing two doors or lid opening and closing, or opening and closing simultaneously, or opening and closing respectively.The function of opening and closing is simultaneously simple, sometimes can not meet specific demand; Respectively opening and closing in requisition for Liang Tao mechanism, take up room large, loaded down with trivial details, cost is high.
Summary of the invention
The problems referred to above that the present invention exists to solve existing door closure opening and closing structure, provide a kind of two-door-linkage structure.
The present invention adopts following technical scheme to realize:
Two-door-linkage structure, comprises transmission arm, bearing, lock, hammerlock, stopping means and two-way cylinder,
Door I arranges transmission arm, and door II arranges two-way cylinder, two-way cylinder push rod connects hammerlock upper end, the lower end of hammerlock is provided with the locking round pin parallel with two-way cylinder push rod,
Bearing comprises left riser and right riser, left and right riser upper end all has coaxial through hole, one end of transmission arm also has the through hole coaxial with riser upper end, left and right through hole, two-way cylinder push rod is pluggable in the through hole of riser upper end, left and right and transmission arm, left riser lower end to extend outside a body and also has through hole
Lock is fixed on car body, lock has the through hole coaxial with left riser lower end through hole, and hammerlock lower end locking round pin is pluggable in the through hole of lock and left riser lower end,
Be connected with the stopping means that two parallel-plates are formed between two-way cylinder cylinder body and bearing, two parallel-plates are parallel with two-way cylinder push rod, and hammerlock clamps by two parallel-plates.
Beneficial effect of the present invention: can make two doors or cover opening and closing simultaneously or an only opening and closing, simply, reliable, cost is low.
Accompanying drawing explanation
Fig. 1 is structural representation of the present invention,
In figure: 1-door (or lid) I, 2-door (or lid) II, 3-transmission arm, 4-bearing, 5-lock, 6-hammerlock, 7-stopping means, 8-two-way cylinder, 9-two-way cylinder push rod, 10-locking round pin.
Detailed description of the invention
By reference to the accompanying drawings the specific embodiment of the present invention is described further.
As shown in Figure 1, two-door-linkage structure, comprises transmission arm 3, bearing 4, lock 5, hammerlock 6, stopping means 7 and two-way cylinder 8, and two-way cylinder is the qigong or surges,
Door I 1 arranges transmission arm 3, and door II 2 is arranged two-way cylinder 8, two-way cylinder push rod 9 connects hammerlock 6 upper end, the lower end of hammerlock 6 is provided with the locking round pin 10 parallel with two-way cylinder push rod 9,
Bearing 4 comprises left riser and right riser, left and right riser upper end all has coaxial through hole, one end of transmission arm 3 also has the through hole coaxial with riser upper end, left and right through hole, two-way cylinder push rod 9 is pluggable in the through hole of riser upper end, left and right and transmission arm, left riser lower end to extend outside a body and also has through hole
Lock 5 is fixed on car body, lock 5 has the through hole coaxial with left riser lower end through hole, and hammerlock 6 lower end locking round pin 10 is pluggable in the through hole of lock and left riser lower end,
Stopping means 7, two parallel-plate being connected with two parallel-plates formations between two-way cylinder 8 cylinder body and bearing 4 is parallel with two-way cylinder push rod, and hammerlock clamps by two parallel-plates.
When two-way cylinder push rod 9 is released, be cascaded through the hole on transmission arm 3 and bearing 4, simultaneously, hammerlock 6 stretches out with two-way cylinder push rod 9, locking round pin 10 on hammerlock 6 departs from from the hole bearing 4 and lock 5, relieve the locking states of door (or lid) II 2, door (or lid) II 2 and door (or lid) I 1 are cascaded completely, can transverse linkage opening and closing.
When two-way cylinder push rod 9 is retracted, depart from the hole on transmission arm 3 and bearing 4, namely door (or lid) II 2 is separated from series connection with door (or lid) I 1, simultaneously, hammerlock 6 is retracted with two-way cylinder push rod 9, and the locking round pin on hammerlock 6 is connected with the hole on lock 5 through bearing 4, and door (or lid) II 2 is in locking states, can not opening and closing again, door (or lid) I 1 still can horizontal opening and closing.The effect of stopping means 7 is that restriction hammerlock 6 rotates with two-way cylinder push rod 9, to guarantee that the locking round pin on hammerlock 6 can penetrate in the hole on bearing 4 and lock 5 smoothly.
