When the buckle shaft 70 of above-mentioned linkage structure 100 and retaining ring 130 are fastened and connected, first the buckle of buckle shaft 70 74 is inserted in the strip through-hole 138 of retaining ring 130.Then, rotation hand wheel 10, the pinion on handwheel 10 is along with handwheel rotates, and because pinion and spur wheel 30 engage, pinion drives spur wheel 30 to rotate.Spur wheel 30 and the first helical gear 40 are coaxial, and when spur wheel 30 rotates, the first helical gear 40 is along with rotation, thereby drive the second helical gear 52 rotates.The second helical gear 52 drives iron axle 54 to rotate.When rotating, the second helical gear 52 and iron axle 54 advance toward the direction of retaining ring 130.Because clutch 80 is set on iron axle 54, when rotating, is with on iron axle 54 dynamic clutch 80 to rotate forward, and clutch 80 is with moving ring sleeve 120 to rotate.In the time that bounding means 110 contacts with the inwall of retaining ring 130, ring set 120 continues the direction motion to retaining ring 130 under the thrust of the second helical gear 52, now, due to being fixedly connected with of bounding means 110 and running shaft 72, bounding means 110 is because keeping out of retaining ring 130 can not be advanced to retaining ring 130 directions again, thereby buckle shaft 70 is not readvanced.Because clutch 80 is fixedly connected with running shaft 72, clutch 80 no longer advances to the direction of retaining ring 130, thereby makes iron axle 54 continue to advance to retaining ring 130 direction rotations with respect to clutch 80, and is with dynamic clutch 80 and running shaft 72 to rotate.Thereby after making buckle 74 rotation and retaining ring 130 closely engage.When iron axle 54 moves in clutch 80, because clutch 80 and 70 rotations of buckle shaft are not advanced, thereby make buckle shaft 70 compression elastic pieces 60, make elastic component 60 in compressive state.
When the buckle shaft 70 of above-mentioned linkage structure 100 separates with retaining ring 130, opposite spin handwheel 10, pinion is along with handwheel 10 rotates, and pinion drives spur wheel 30 to rotate.When spur wheel 30 rotates, the first helical gear 40 is along with rotation, thereby drive the second helical gear 52 rotates, and the second helical gear 52 drives iron axle 54 to rotate.When rotating, the second helical gear 52 and iron axle 54 move toward the direction away from retaining ring 130.Iron axle 54 rotates toward the direction away from retaining ring 130 with dynamic clutch 80.Clutch 80 drives buckle shaft 70 to rotate toward the direction away from retaining ring 130.Now, because elastic component 60 is in compressive state, elastic component 60 gives buckle shaft 70 1 thrusts toward retaining ring 130 directions, buckle shaft 70 can effectively reduce the suffered power away from retaining ring 130 directions of buckle shaft 70 under the effect of the elastic force of elastic component 60, buckle 74 can be rotated flexibly, thereby can be from the strip through-hole of retaining ring 130 138 out, buckle shaft 70 is separated with retaining ring 130.
Be appreciated that pinion can omit, and is now directly fixedly connected with handwheel 10 with spur wheel.Or handwheel 10 and pinion can omit, now, by directly spur wheel 30 being rotated and can driving the first helical gear 40 to rotate.Or handwheel 10, pinion and spur wheel 30 can omit, now, directly rotate the first helical gear 40.
Introduce the application of linkage structure 100 in display screen box body connects below.In this application, the edge of the first display screen box body 200 and second display screen casing 300 has certain radian.Please also refer to Figure 10 and Figure 11, the first display screen box body 200 offers the first mounting hole 220.The sidewall of the first mounting hole 220 is provided with boss 224, offers screw (figure is mark not) on boss 224.Sliding assembly 140 and retaining ring 130 are located in the first mounting hole 220.Sliding assembly 140 with on boss 224, offer screw and be directly fixedly connected with.Second display screen casing 300 offers the second mounting hole 320.Mounting shell 20 is located in the second mounting hole 320.Mounting shell 20 is fixedly connected with second display screen casing 300.Pinion, spur wheel 30, the first helical gear 40, actuator 50, elastic component 60, buckle shaft 70, clutch 80, pin 90, bounding means 110 are located in mounting shell 20.The buckle of buckle shaft 70 74 is inserted after the strip through-hole 138 of retaining ring 130, buckle shaft 70 and retaining ring 130 can be fastened by rotation hand wheel 10, the first display screen box body 200 is connected with second display screen casing 300.By moving the first display screen box body 200, sliding assembly 140 can slide with respect to the arc flank 134 of retaining ring 130, sliding assembly 140 drives the first display screen box body 200 to produce and slide with respect to retaining ring 130, thereby makes to produce certain radian between the first display screen box body 200 and second display screen casing 300.
Above-mentioned linkage structure 100, can drive buckle shaft 70 to rotate by rotation hand wheel 10, by clutch 80 and elastic component 60 are set, when buckle shaft 70 fastens or separates with retaining ring 130, by compression elastic piece 60 or under the elastic force effect of elastic component 60, can effectively reduce the power along axial direction that buckle shaft 70 is subject to, thereby make buckle 74 more flexible in the time that retaining ring 130 rotates.100 of above-mentioned linkage structures need rotation hand wheel 10 half-turns to settle at one go display screen box body is fastened together, and assembling mode is simple.
Above-mentioned linkage structure 100, can drive buckle shaft 70 to rotate by rotation hand wheel 10, thereby buckle 74 and retaining ring 130 are fastened.When linkage structure 100 is applied to casing connection, after buckle 74 and retaining ring 130 are fastened, by slip sliding assembly 140, sliding assembly 140 can drive the box body-sliding being fixedly connected with sliding assembly 140, thereby two casings that linkage structure 100 is connected are curved.Above-mentioned linkage structure 100 low cost of manufactures, can directly flat display panel be spliced to form to curved face type display screen.
The above embodiment has only expressed several mode of execution of the present utility model, and it describes comparatively concrete and detailed, but can not therefore be interpreted as the restriction to the utility model the scope of the claims.It should be pointed out that for the person of ordinary skill of the art, without departing from the concept of the premise utility, can also make some distortion and improvement, these all belong to protection domain of the present utility model.Therefore, the protection domain of the utility model patent should be as the criterion with claims.
