Description
Technical field
The utility model relates to high ferro accessory, particularly a kind of rotary support composite lock locking mechanism.
Background technology
Current most of high-speed rail seat can rotate, and is therefore provided with rotating disk, but rotating disk is relative to the biased segment distance of seat center, and this is unfavorable to structure stress.Be provided with secondary support means, this device is again catch gear simultaneously for this reason.
Summary of the invention
The purpose of this utility model is the deficiency overcoming above-mentioned technology, thus provides a kind of rotary support composite lock locking mechanism, can support and can reach the object of locking.
The technical scheme that the utility model adopts is such: rotary support composite lock locking mechanism, comprise underframe, described underframe rotates and is provided with wheel shaft, one end of described wheel shaft is provided with locking wheel, its other end is provided with support wheel, described locking wheel is provided with the projection matched with the locked groove on balladeur train, described wheel shaft is fixedly installed drive wheel, described drive wheel is connected with drag-line, described wheel shaft slides axially along it and is provided with clutch dog, described clutch dog is provided with lock pin, described locking wheel offers the lockhole matched with described lock pin, be provided with between described clutch dog and described drive wheel and make described lock pin insert elastic component in described lockhole, described underframe is provided with and makes described locking take turns the release mechanism unlocked with described clutch dog.
Further improvement: described release mechanism comprises middle part and rotates the rod be arranged on described underframe, and match with balladeur train in one end of described rod, its other end has driving inclined-plane, described clutch dog has the guiding surface matched with described driving inclined-plane.
Further improvement: be connected by pin between described drive wheel with described wheel shaft.
Further improvement: described drag-line is connected with control pedal.
By adopting preceding solution, the beneficial effects of the utility model are: support wheel supports balladeur train, and locking wheel, for locking balladeur train, therefore possesses and supports and locking two functions.

Fig. 2 is cutaway view of the present utility model.
Wherein: 1, underframe; 2, wheel shaft; 3, locking wheel; 4, support wheel; 5, protruding; 6, balladeur train; 7, drive wheel; 8, drag-line; 9, clutch dog; 10, lock pin; 11, lockhole; 12, elastic component; 13, rod.
Detailed description of the invention
The utility model is further illustrated below in conjunction with the drawings and specific embodiments.
As Figure 1-Figure 2, the utility model discloses a kind of rotary support composite lock locking mechanism, comprise underframe 1, described underframe 1 rotates and is provided with wheel shaft 2, one end of described wheel shaft 2 is provided with locking wheel 3, its other end is provided with support wheel 4, described locking wheel 3 is provided with the projection 5 matched with the locked groove on balladeur train 6, described wheel shaft 2 is fixedly installed drive wheel 7, described drive wheel 7 is connected with drag-line 8, described wheel shaft 2 slides axially along it and is provided with clutch dog 9, described clutch dog 9 is provided with lock pin 10, described locking wheel 3 offers the lockhole 11 matched with described lock pin 10, be provided with between described clutch dog 9 and described drive wheel 7 and make described lock pin 10 insert elastic component 12 in described lockhole 11, described underframe 1 is provided with and makes described locking take turns 3 release mechanisms unlocked with described clutch dog 9.
The technical scheme optimized in the present embodiment is, described release mechanism comprises middle part and rotates the rod 13 be arranged on described underframe 1, match with balladeur train 6 in one end of described rod 13, its other end has driving inclined-plane, described clutch dog 9 has the guiding surface matched with described driving inclined-plane.
The technical scheme optimized in the present embodiment is, is connected between described drive wheel 7 with described wheel shaft 2 by pin.
The technical scheme optimized in the present embodiment is, described drag-line 8 is connected with control pedal.
Principle of work: when step affects drag-line 8, drag-line 8 affects drive wheel 7 to rotate, locking wheel 3 rotates, protruding 5 depart from the locked groove on balladeur train 6, rotate and unlock, the lock pin 10 of clutch dog 9 end face inserts in the lockhole 11 of locking wheel 3 simultaneously, locking wheel 3 locking is no longer lifted, balladeur train 6 is rotatable, seat commutates, seat commutation puts in place, balladeur train 6 overlaps with underframe 1 gradually, the block of balladeur train 6 bottom promotes rod 13 and presses down, rod 13 other end tilts, driving slope driving clutch dog 9 on it moves vertically, the lock pin 10 of clutch dog 9 end face is extracted out from the lockhole 11 locking wheel 3, support wheel 4 lifts, play supporting role, the locking wheel 3 of band protruding 5 is wedged bottom balladeur train 6 and in locked groove, balladeur train 6 is locked simultaneously.
More than show and describe groundwork of the present utility model and principal character and advantage thereof; the technical personnel of the industry should be understood; the utility model is not restricted to the described embodiments; above-described embodiment just illustrates principle of the present utility model with description in explanation; under the prerequisite not departing from the utility model spirit and scope; the utility model also has various changes and modifications; these changes and improvements all fall within the scope of claimed the utility model, and the claimed scope of the utility model is defined by appending claims and equivalent thereof.
