A locking operating device is arranged between the base and the locking plate. By means of the structure, the transmission wheel can be locked and operated conveniently, and locking is reliable.
Description
Technical field
The utility model relates to stage lighting, particularly the belt wheel position locking mechanism in stage lighting.
Background technology
In light fixture, particularly in stage lamp, movable parts pass through motor driving gear or band wheel drive as focus control, effect disk, color dish or pattern disk, and in the actual use procedure of light fixture, need to lock movable parts, past is common realizes by controlling motor, but the locking of this method is insecure.
Summary of the invention
In order firmly to lock movable parts, the utility model provides a kind of belt wheel position locking mechanism.
For achieving the above object, a kind of belt wheel position locking mechanism, comprise pedestal, on pedestal, be provided with drive, on drive, depart from pivot and be provided with lock-bit post, be articulated with lock-bit plate in the upper side in drive of pedestal, lock-bit plate is provided with the lock-bit groove of energy holding lock-bit post, between pedestal and lock-bit plate, is provided with the first elastic component; Between pedestal and lock-bit plate, be provided with locking operation device.
Said structure, under the effect of the first elastic component and locking operation device, can allow lock-bit plate swing, in the time that lock-bit plate swings towards drive direction, lock-bit post snaps onto in lock-bit groove, prevents drive rotation, in the time that lock-bit backboard the swing of drive direction, lock-bit post separates with lock-bit groove, and drive is rotatable, and the lock-bit plate direct effect of the utility model structure is realized the locking to drive to drive, therefore, the locking of drive firmly, reliably.
Further, described locking operation device comprises rotary handle, arm-tie and the second elastic component; Rotary handle is located on pedestal; One end of arm-tie is provided with chute, on lock-bit plate, is provided with and draws pin, draws one end of pin through chute, and the other end of arm-tie is articulated on rotary handle; The second elastic component is located between pedestal and arm-tie.This structure, when to a direction rotation rotary handle, arm-tie under the effect of the second elastic component by chute and draw the guiding of pin to move towards drive direction, remove the restriction of arm-tie to lock-bit plate, lock-bit plate is at the effect lower swing of the first elastic component, lock-bit groove is snapped onto on lock-bit post, thereby reach the object of restriction drive rotation.When rotating in the opposite direction rotary handle, arm-tie overcomes the second elastic component elastic force and moves in the opposite direction, pulls lock-bit plate to depart from lock-bit post.Therefore, this structure is convenient to the lock operation of drive, and locking is reliable.
Further, be provided with the first drag hook in one end of lock-bit plate, pivot joint position is near one end of the first drag hook, and lock-bit groove is located on the lock-bit plate away from first drag hook one end; The first described elastic component is the first extension spring, and one end of the first extension spring is located on the first drag hook, and the other end of the first extension spring is located on pedestal by the first hanging column.By the first drag hook, the first extension spring is set, the first extension spring easy to connect, reliable.
Further, described arm-tie is provided with the second drag hook; The second described elastic component is the second extension spring, and one end of the second extension spring is located on the second drag hook, and the other end of the second extension spring is located on pedestal by the second hanging column.By the second drag hook, the second extension spring is set, the second extension spring easy to connect, reliable.
Brief description of the drawings
Fig. 1 is the schematic diagram of the utility model structure.
Fig. 2 is the exploded view of the utility model structure.
Detailed description of the invention
Below in conjunction with the drawings and specific embodiments, the utility model is further elaborated.
As depicted in figs. 1 and 2, belt wheel position locking mechanism comprises pedestal 1, and pedestal 1 comprises that base plate 11 and two relative edges from base plate are bent upwards the side plate 12 of moulding.
On base plate 11, by bearing, drive 2 is installed, in the present embodiment, drive 2 is belt wheel.The position of departing from pivot on belt wheel is provided with lock-bit post 3.A side that is positioned at belt wheel on base plate 11 is provided with drive-connecting shaft 4, is articulated with lock-bit plate 5 on drive-connecting shaft 4, and the side near drive-connecting shaft 4 on lock-bit plate 51 is provided with the first drag hook 51, on arm-tie 5, is provided with lock-bit groove 52 away from drive-connecting shaft and on a side of belt wheel; The first hanging column 7 is installed on base plate 11, between the first hanging column 7 and the first drag hook 51, is provided with the first elastic component 6, the first described elastic component is the first extension spring.
On base plate 11, be also provided with locking operation device, described locking operation device comprises rotary handle 81, arm-tie 82 and the second elastic component 83.Rotary handle 81 is located on base plate 11; One end of arm-tie 82 is provided with chute 821, be provided with and draw pin 53 away from one end of drive-connecting shaft at lock-bit plate 5, draw cover on pin 53 to have a collar 531, draw one end of pin through chute 821, and the collar is positioned at chute, in the time of arm-tie rectilinear motion, the collar 531 can be relative to drawing pin 53 to rotate, thereby the resistance that reduces arm-tie motion, the other end of arm-tie 82 is articulated on the edge of rotary handle; Described arm-tie is provided with the second drag hook 822.On base plate 11, be provided with the second hanging column 84.The second described elastic component is the second extension spring, and the second extension spring is located between the second hook and the second hanging column.
The operating process of this structure is: when the rotary handle 81 that turns clockwise, arm-tie 82 moves towards drive direction by the guiding of chute 821 and the collar 531 under the effect of the second extension spring, remove the restriction of arm-tie 82 to lock-bit plate 5, lock-bit plate 5 is at the effect lower swing of the first extension spring 6, lock-bit groove 52 is snapped onto on lock-bit post 3, thereby reach the object of restriction belt wheel rotation.Be rotated counterclockwise rotary handle 81, the elastic force that arm-tie 82 overcomes the second extension spring moves in the opposite direction, pulls lock-bit plate 5 to depart from lock-bit post 3, and belt wheel is rotatable.Therefore, this structure is convenient to the lock operation of drive, and locking is reliable.
