Embodiment
For the ease of understanding the utility model, below with reference to relevant drawings, the utility model is described more fully.In accompanying drawing, provided preferred embodiment of the present utility model.But the utility model can be realized with multiple different form, is not limited to embodiment described herein.On the contrary, providing these embodiments' object is to make to the understanding of disclosure of the present utility model more thoroughly comprehensively.
Unless otherwise defined, all technology of using are herein identical with the implication that belongs to the common understanding of those skilled in the art of the present utility model with scientific terminology.The term using in specification of the present utility model herein, just in order to describe the object of specific embodiment, is not intended to be restriction the utility model.
The connection set 10 of a mode of execution as shown in Figure 1 comprises handwheel 110, pinion (not shown), mounting shell 120, spur wheel 125, the first helical gear 130, actuator 140, clutch 150, buckle shaft 160, elastic component 165, pin 170, bounding means 175, ring set 180 and retaining ring 190.
Handwheel 110 is fixedly connected with pinion, pinion and spur wheel 125 engagements.
Actuator 140 comprises the second helical gear 142 and is fixed on the iron axle 144 of second helical gear 142 one end, the center of one end that is provided with iron axle 144 of actuator 140 is provided with groove, groove runs through described iron axle 144 and extends in the second helical gear 142, the periphery of iron axle 144 offers latch groove 1442, latch groove 1442 is parallel with the axial direction of iron axle 144, the first helical gear 130 and the second helical gear 142 engagements.The periphery of iron axle 144 offers latch groove 1442, and latch groove 1442 is parallel with the axial direction of iron axle 144.The periphery of iron axle 144 is provided with raised line 1444, and raised line 1444 is parallel with the axial direction of iron axle 144.
Clutch 150 is set on iron axle 144.The periphery of clutch 150 offers fixed via (not shown).Iron axle 144 can be with dynamic clutch 150 to rotate.The inwall of clutch 150 is provided with the hole groove with raised line 1444 couplings.Because raised line 1444 is parallel with the axial direction of iron axle 144, can make the relative clutch 150 of iron axle 144 carry out relative movement along the axial direction that is parallel to iron axle 144.The periphery of clutch 150 is provided with projection 152.
Bounding means 175 is fixed on running shaft 164 away from the periphery of one end of spring 165.In the present embodiment, bounding means 175 is cylinder spring.Cylinder spring is relatively fixed and is formed by two semicircular ring.Being screwed of two semicircular ring is connected to form ring.Two semicircular ring are fixedly connected with by pin with running shaft 164.Cylinder spring is comprised of two semicircular ring, easier for installation.
As shown in Figure 2, retaining ring 190 comprises top cover 194.Top cover 194 offers strip through-hole 192, and buckle 162 is through the rear rotation of strip through-hole 192, and buckle 162 and retaining ring 190 fasten.
When the buckle shaft 160 of above-mentioned connection set 10 and retaining ring 190 are fastened and connected, first the buckle of buckle shaft 160 162 is inserted in the strip through-hole 192 of retaining ring 190.Then, rotation hand wheel 110, the pinion on handwheel 110 is along with handwheel rotates, and due to pinion and spur wheel 125 engagements, pinion drives spur wheel 125 to rotate.Spur wheel 125 and the first helical gear 130 are coaxial, and when spur wheel 125 rotates, the first helical gear 130 is along with rotation, thereby drive the second helical gear 142 rotates.The second helical gear 142 drives iron axle 144 to rotate.The second helical gear 142 and iron axle 144 advance toward the direction of retaining ring 190 when rotating.Because clutch 150 is set on iron axle 144, when rotating, iron axle 144 is with dynamic clutch 150 to rotate forward, and clutch 150 band moving ring sleeves 180 rotate.When the inwall of bounding means 175 and retaining ring 190 contacts, ring set 180 continues the direction motion to retaining ring 190 under the thrust of the second helical gear 142, now, due to being fixedly connected with of bounding means 175 and running shaft 164, bounding means 175 is because keeping out of retaining ring 190 can not be advanced to retaining ring 190 directions again, thereby buckle shaft 160 is not readvanced.Because clutch 150 is fixedly connected with running shaft 164, clutch 150 no longer advances to the direction of retaining ring 190, thereby makes iron axle 144 continue to advance to retaining ring 190 direction rotations with respect to clutch, and band dynamic clutch 150 and running shaft 164 rotations.Thereby after making buckle 162 rotation and retaining ring 190 closely engage.When iron axle 144 moves in clutch 150, because clutch 150 and 160 rotations of buckle shaft are not advanced, thereby make buckle shaft 160 compression elastic pieces 165, make elastic component 165 in compressive state.
When the buckle shaft 160 of above-mentioned connection set 10 is separated with retaining ring 190, opposite spin handwheel 110, pinion is along with handwheel 110 rotations, and pinion drives spur wheel 125 to rotate.When spur wheel 125 rotates, the first helical gear 130 is along with rotation, thereby drive the second helical gear 142 rotates, and the second helical gear 142 drives iron axles 144 to rotate.The second helical gear 142 and iron axle 144 move toward the direction away from retaining ring 190 when rotating.Iron axle 144 rotates toward the direction away from retaining ring 190 with dynamic clutch 150.Clutch 150 drives buckle shaft 160 to rotate toward the direction away from retaining ring 190.Now, because elastic component 165 is in compressive state, elastic component 165 gives buckle shaft 160 1 thrusts toward retaining ring 190 directions, buckle shaft 160 can effectively reduce the suffered power away from retaining ring 190 directions of buckle shaft 160 under the effect of the elastic force of elastic component 165, buckle 162 can be rotated flexibly, thereby can from the strip through-hole 192 of retaining ring 190 out, make buckle shaft 160 separated with retaining ring 190.
Be appreciated that pinion can omit, and is now directly fixedly connected with handwheel 110 with spur wheel.Or handwheel 110 and pinion can omit, now, by directly spur wheel 125 being rotated, can drive the first helical gear 130 to rotate.Or handwheel 110, pinion and spur wheel 125 can omit, now, directly rotate the first helical gear.
Introduce the application of connection set 10 in display screen box body splicing below.As shown in Figure 3, the first display screen box body 20 offers the first mounting hole 22.Retaining ring 190 is located in the first mounting hole 22.Retaining ring 190 is fixedly connected with the first display screen box body 20.Second display screen casing 30 offers the second mounting hole 32.Mounting shell is located in the second mounting hole 32.Mounting shell is fixedly connected with second display screen casing 30.The buckle of buckle shaft is inserted after the strip through-hole of retaining ring 190, by rotation hand wheel 110, buckle shaft and retaining ring 190 can be fastened, thereby make the first display screen box body 20 and 30 splicings of second display screen casing.
Above-mentioned connection set 10, by rotation hand wheel 110, can drive buckle shaft 160 rotations, by clutch 150 and elastic component 165 are set, buckle shaft 160 fastens with retaining ring 190 or when separated, by compression elastic piece 165 or under the elastic force effect of elastic component 165, can effectively reduce the power along axial direction that buckle shaft 160 is subject to, thereby make buckling part 162 more flexible when retaining ring 190 rotates.10 of above-mentioned connection sets need rotation hand wheel 110 half-turns to settle at one go display screen box body is fastened together, and assembling mode is simple.
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.
