The specific embodiment
For technological means, creation characteristic that this utility model is realized, reach object and effect is easy to understand, below in conjunction with concrete diagram, further set forth this utility model.
Referring to Fig. 1, a kind of endoscope handwheel retaining mechanism that this utility model provides, it mainly comprises handwheel latch assembly 100, handwheel bent angle assembly 200 and main shaft 300.
Handwheel bent angle assembly 200 is placed on main shaft 300, its concrete setting is: the middle part of its inner all parts is all offered to through hole, then main shaft 300 runs through the through hole on all parts on handwheel bent angle assembly 200 successively, and all parts on handwheel bent angle assembly 200 successively lamination is placed on main shaft 300.
Handwheel bent angle assembly 200, when being subject to ambient pressure, can moving down certain distance along main shaft 300, and self can be locked.
Referring to Fig. 2, handwheel bent angle assembly 200 comprises the directed dish 270 of handwheel sealing frame 210, damping mechanism and handwheel from top to bottom successively, these parts are together run through by main shaft 300, and lamination is placed on main shaft 300 successively, and handwheel sealing frame 210 and damping mechanism can carry out displacement along main shaft 300.
The directed dish 270 of handwheel offers resettlement groove 271 on the directed dish 270 of handwheel, is provided with circular boss 272 in resettlement groove 271.
The inner circle of circular boss 272 is run through by main shaft 300, is provided with bayonet socket 272a on boss 272, in boss 272 both sides, is provided with connecting hole 273.
For the directed dish 270 of handwheel is axially fixed on main shaft 300, in the directed dish 270 of handwheel, be provided with opening inserted sheet 250.
Opening inserted sheet 250, is a rustless steel disk, overlays on boss 272, and its concrete size matches with the boss 272 on the directed dish 270 of handwheel, and position offers U-lag 251 therebetween, in its both sides, offers connecting hole 252.
U-lag 251 matches with the step cutting pattern 320 on main shaft 300, and opening inserted sheet 250 can be inserted on main shaft 300 by U-lag 251, and is axially fixed on main shaft 300.
The connecting hole 252 of opening inserted sheet 250 both sides matches with the fixing hole 272 on the directed dish 270 of handwheel, when opening inserted sheet 250 is placed on the step cutting pattern 271 on the directed dish 270 of handwheel, opening inserted sheet 250 can be fixed on the directed dish 270 of handwheel by screw and fixing hole 272.
Like this, opening inserted sheet 250 is fixedly connected with the step cutting pattern 320 on main shaft 300 by U-lag 251, by the directed dish 270 of connecting hole 252 and handwheel, be fixedly connected with, thereby realized, directed handwheel dish 270 is axially fixed on main shaft 300, the directed dish 270 of handwheel can only be rotated on main shaft 300, can not carry out displacement.
Damping mechanism comprises damping fin fixing head 220, damping fin 230, damping sheet 240 and plane spring 260, they successively lamination be placed in the directed dish 270 of handwheel, damping mechanism can be locked directed handwheel dish 270.
Damping fin fixing head 220, damping fin 230 and damping sheet 240 overlay on the spring leaf 261 on plane spring 260 successively.
When the bayonet socket 272a on the bayonet socket 241 on damping sheet 240 and boss 272 is not during in same straight line, damping sheet 240 can only be parked in the top of boss 272, and damping sheet 240 just can not be along with boss 272 rotates together like this.
When damping sheet 240 moves down on main shaft 300, can be by the spring leaf on plane spring 260 261 to pressing down, when damping sheet 240 is set on boss 272, damping sheet 240 can be pressed onto spring leaf 261 parallel with plane spring 260, at this moment, damping sheet 240 can be pressed on the circular ring plate of spring leaf 261, because spring leaf 261 is fixed on boss 272, damping sheet 240 can stop moving down, and this is that spring leaf 261 can provide lasting elastic potential energy to damping sheet 240.
When the ambient pressure of receiving when damping sheet 240 disappears, spring leaf 261 can eject damping sheet 240 from boss 272, and damping sheet 240 receives that the resilience force of spring leaf 261 can be reset to initial position, and at this moment damping sheet 240 can not rotate together along with boss 272.
Damping fin 230, Wei Yi opens at center round-meshed disk, and damping sheet 240 tops are set, and it adopts nylon material to make, and when damping sheet 240 is along with boss 272 is together initiatively time, damping fin 230 is understood produce stronger frictional force to damping sheet 240 like this.
Damping fin 230 is fixed on the below of damping fin fixing head 220 by glue.
Damping fin fixing head 220Wei mono-center is with the rustless steel disk of square hole 221, and this square hole 221 matches with square step 310 on main shaft 300, and damping fin fixing head 220 can be set on main shaft 300 by square hole 221 like this.
Because damping fin fixing head 220 center is square hole 221, so damping fin fixing head 220 can only be at the enterprising line displacement of main shaft 300, and can not rotate together along with main shaft 300, and damping fin 230 is the belows that are fixed on damping fin fixing head 220, so damping fin 230 also can only be at the enterprising line displacement of main shaft 300, and can not on main shaft 300, rotate, like this when damping sheet 240 is set in while rotating on boss 272, damping fin 230 can produce damping to damping sheet 240, thereby damping sheet 240 cannot be rotated along with boss 272, and also by damping sheet 240, boss 272 cannot be rotated, thereby by directed handwheel dish 270 lockings
Damping mechanism is as follows with coordinating of the directed dish 270 of handwheel:
When damping mechanism is subject to extraneous extruding, can be along main shaft 300 to bottom offset, after moving a certain distance, at this moment the damping sheet 240 on damping mechanism can rest on the boss 272 in the directed dish 270 of handwheel, and the directed boss 272 coiling in 270 of handwheel can rotate on main shaft 300, when the bayonet socket 272a on boss 272 turn to damping sheet 240 on bayonet socket 241 on same straight line time, damping sheet 240 can continue to move down, be set on boss 272, can be along with boss 272 rotates together, and at this moment, the damping fin 230 that is arranged on damping sheet 240 tops is fixed on damping fin fixing head 220, cannot on main shaft 300, rotate, so, when damping sheet 240 is set in while rotating on boss 272, damping fin 230 can produce damping to damping sheet 240, thereby damping sheet 240 cannot be rotated along with boss 272, and also by damping sheet 240, boss 272 cannot be rotated, thereby by directed handwheel dish 270 lockings,
When the pressure on damping mechanism disappears, plane spring 260 on damping mechanism can eject damping sheet 240 from boss 272, damping sheet 240 receives that the resilience force of spring leaf 261 can promote damping fin 230 again and damping fin fixing head 220 moves up along main shaft 300, thereby be reset to initial position, and at this moment damping sheet 240 can leave boss 272, the directed dish 270 of handwheel can be rotated further again, and locking disappears.
Referring to Fig. 3, handwheel latch assembly 100 comprises rotary apparatus, angle adjusting mechanism and spacing directed dish 150 from top to bottom successively, and these parts laminations are placed on main shaft 300.
Spacing directed dish 150, be provided with therebetween the screw 151 matching with the screw thread on square step 310, spacing directed dish 150 can be screwed on main shaft 300 by screw 151, and can on main shaft 300, carry out clockwise and be rotated counterclockwise, spacing directed dish 150, when being rotated counterclockwise, can push handwheel bent angle assembly 200.
