Description
Technical field
The utility model belongs to stopping sliding door technical field, and in particular to a kind of stopping sliding door transmission mechanism.
Background technology
With developing rapidly for bullet train and urban track traffic, the quality of stopping sliding door is also with continuous improvement. and it is existing
Sliding plug door system is unstable due to being driven, and quality is larger, and noise is larger, particularly on the rail vehicle under high-speed motion, meeting
Certain dangerous generation, existing plug door device is caused without interruption means in door opening process, to be held when door leaf reaches two ends
Easily collide, cause stopping sliding door to be damaged.Therefore design that a kind of stable drive, good airproof performance, lighter weight, noise be little and band
The sliding plug door system for having interruption means is very necessary.
The content of the invention
The purpose of this utility model is to provide a kind of stopping sliding door transmission mechanism, and stopping sliding door is without in solution prior art
Disconnected device, door leaf is susceptible to collision when reaching two ends, cause the impaired technical problem of stopping sliding door.
For above-mentioned technical problem, the utility model is adopted the following technical scheme that：
A kind of stopping sliding door transmission mechanism, including support, the first leading screw and the second leading screw, the first leading screw and the second leading screw pass through
Shaft coupling connects, and the first leading screw, the second leading screw are rotatably arranged on support respectively away from one end of shaft coupling by bearing, and first
The thread rotary orientation of leading screw and the second leading screw is arranged with the first nut conversely, pitch is identical on the first screw mandrel, be arranged on the second leading screw
Second nut, the first nut is fixedly connected with the first Xie Men mechanisms, and the second nut is fixedly connected with the second Xie Men mechanisms, first
Bar is connected away from one end of shaft coupling with actuator；First leading screw, the second leading screw are respectively provided with one end of bearing
There is proximity switch.
During enabling, driving means drive the first leading screw to rotate, and the first leading screw is rotated and drives the second leading screw to rotate, due to first
The thread rotary orientation of leading screw and the second leading screw conversely, then the first nut, the second nut towards contrary reverse movement, so as to drive first
Xie Men mechanisms, the second Xie Men mechanisms are moved away from, and door is opened.Because the first leading screw, the pitch of the second leading screw are identical, then first
Nut, the second nut translational speed are identical, improve resistance to overturning, it is ensured that the enabling speed of two door leafs is identical.At closing time, drive
Dynamic device drives the first leading screw to rotate backward, then the first nut, the second nut be towards contrary reverse movement, so as to drive first to take
Door mechanism, the relative movement of the second Xie Men mechanisms, door is closed.By being positioned proximate to switch, in door opening process, first takes a machine
Structure, second take a mechanism contacts to the proximity switch at two ends, then driving means quit work, prevent the first Xie Men mechanisms, second
Support collides in Xie Men mechanisms, causes whole device unstability, damages.
Further improve, also including supporting slider mechanism, the supporting slider mechanism includes support bar and two sliding sleeves,
Strut two ends are fixed on support, and support bar be arranged in parallel with the first leading screw, the second leading screw, the equal slidingtype of described two sliding sleeves
It is set on support bar, and two sliding sleeves are connected respectively with the first Xie Men mechanisms, the second Xie Men mechanisms.Due to Xie Men mechanisms, door
Fan is heavier, during switch gate is repeated several times, the first leading screw, the deformation of the second leading screw can be made, so as to cause whole stopping sliding door to be tied
Structure is damaged, and by arranging supporting slider mechanism, support bar plays a part of to make to Xie Men mechanisms, load-bearing, prevent the first leading screw,
Second leading screw deforms because of excessive load-bearing.
Compared with prior art, the beneficial effects of the utility model are：
1st, by being positioned proximate to switch, in door opening process, the first Xie Men mechanisms, second take a mechanism contacts and arrive two ends
Proximity switch, then driving means quit work, prevent the first Xie Men mechanisms, the second Xie Men mechanisms collision support, cause whole dress
Unstability is put, is damaged.
2nd, by arranging supporting slider mechanism, support bar plays a part of to make to Xie Men mechanisms, load-bearing, prevents first
Thick stick, the second leading screw deform because of excessive load-bearing.
Description of the drawings
Fig. 1 is a kind of dimensional structure diagram of stopping sliding door transmission mechanism described in the utility model.
Fig. 2 is the front view of Fig. 1.
Specific embodiment
Below in conjunction with the accompanying drawings the utility model is described in further detail with specific embodiment：
As shown in Figure 1, 2, a kind of stopping sliding door transmission mechanism, including support 1, the first leading screw 2, the second leading screw 3, proximity switch
4 and the first Xie Men mechanism 5, the second Xie Men mechanisms 6, support bar 7 and sliding sleeve 8 etc..
A kind of stopping sliding door transmission mechanism, including support, the first leading screw and the second leading screw, the first leading screw and the second leading screw pass through
Shaft coupling connects, and the first leading screw, the second leading screw are rotatably arranged on support respectively away from one end of shaft coupling by bearing, and first
The thread rotary orientation of leading screw and the second leading screw is arranged with the first nut conversely, pitch is identical on the first screw mandrel, be arranged on the second leading screw
