Embodiment 1
Present embodiments provide a kind of laryngoscope, including display unit 100, hand-held part 200 and extending portion 300.
Pass through 400 locking of handle buckle assembly between hand-held part 200 and extending portion 300.
Handle buckle assembly 400 includes：Handle buckles 410, resetting-mechanism 420 and open-and-close mechanism 430.Handle is buckled 410 and is set to
Close to the outer wall of 300 one end of extending portion, the middle part that handle buckles 410 is rotated with by shaft 440 and hand-held part 200 for hand-held part 200
Connection, handle buckle the gap having between 410 tops and the outer wall of hand-held part 200 for accommodating resetting-mechanism 420；
Open-and-close mechanism 430 includes being set to handle to buckle the convex block 431 to the protrusion setting of hand-held part 200 of 410 lower parts, setting
In hand-held part 200 through-hole corresponding with convex block 431 and be set to the slot being connected to through-hole of extending portion 300；Convex
When block 431 is also cross through-hole and slot, hand-held part 200 and extending portion 300 are in lockup state, are not extended into convex block 431 slotting
When slot, hand-held part 200 and extending portion 300 are in the unlocked state.
The course of work of laryngoscope provided by the invention is described below：
When handle, which buckles 410 upper ends, is not affected by pressing active force, resetting-mechanism 420 is in the first stored energy state, and handle is buckled
410 rotate under the driving effect of resetting-mechanism 420 around shaft 440, and the convex block 431 of open-and-close mechanism 430 is also cross through-hole
And slot is stretched into, hand-held part 200 and extending portion 300 are in lockup state at this time.
When handle buckles the depressed active force in outside of 410 upper ends, resetting-mechanism 420 is in the second stored energy state, hand
Handle button 410 is rotated around shaft 440, and the convex block 431 of open-and-close mechanism 430 is detached with slot, at this time hand-held part 200 and extending portion
300 is in the unlocked state.
The advantageous effect that laryngoscope provided in this embodiment can reach is analyzed as follows：
Due to being provided with above-mentioned handle buckle assembly 400, under the action of open-and-close mechanism 430 of handle buckle assembly 400, hold
It can switch between unlocked state and lockup state between portion 200 and extending portion 300.At hand-held part 200 and extending portion 300
When lockup state, resetting-mechanism 420 provides a driving force outside, which has driving handle button 410 to surround
The trend that shaft 440 rotates, handle, which buckles the part that 410 are located at drive shaft lower part, to be had the tendency that towards 200 internal motion of hand-held part,
Thus convex block 431 can push against the inner wall of groove always, avoid loosening, securely be locked between hand-held part 200 and extending portion 300
It is fixed, thus the fastness connected between hand-held part 200 and extending portion 300 can be improved.Also, pass through the unlock of handle buckle assembly
Switching between state and lockup state can conveniently realize the dismounting between hand-held part and extending portion.
It elaborates below to resetting-mechanism 420：
Resetting-mechanism 420 include hand-held part 200 close handle buckle 410 side wall on the locating shaft that is arranged, Yi Jitao
410 springs for extending and offseting are buckled loaded on locating shaft, to handle.More preferably, 410 are buckled in the close handle of hand-held part 200
Side wall on be provided with fluting, locating shaft is installed in fluting.It is further preferable that the end face and hand-held part of the free end of locating shaft
200 lateral wall is located at same surface.Spring pocket is loaded on locating shaft, to ensure that it is inclined that position does not occur in the vertical direction for spring
It moves.Also, the width of fluting should be greater than the width of spring, to accommodate spring completely.
It should be noted that when hand-held part 200 and extending portion 300 are in lockup state, spring is in first and stores power shape
State, there is spring driving handle to buckle 410 trend moved outward, in the unlocked state in hand-held part 200 and extending portion 300
When, spring is in the second stored energy state, likewise, there is spring driving handle to buckle 410 trend moved outward.Also, bullet
Elastic force of the spring under the second stored energy state is more than elastic force of the spring under the first stored energy state.
In the alternative of the present embodiment, the junction of hand-held part 200 and extending portion 300 is additionally provided with laryngoscope and encircles component
500, wherein
Fig. 3, Fig. 6-Figure 10 are please referred to, it includes the contact pin mechanism for being set to 200 end of hand-held part that laryngoscope, which encircles component 500,
510, and it is set to the jack mechanism 520 of 300 end of extending portion, contact pin mechanism 510 and jack mechanism 520 are used cooperatively.It needs
It is noted that Fig. 3 and Fig. 6 are half sectional view, but Fig. 3 is the half sectional view in the directions A-A with reference to Fig. 2, and Fig. 6 is reference
The half sectional view in the directions B-B of Fig. 5, the handle buckle assembly 400 in Fig. 3 are located at front, the handle buckle assembly in Fig. 6 400
In left side.
It elaborates below to contact pin mechanism 510：
Please refer to Fig. 7 and Fig. 8, contact pin mechanism 510 includes contact pin mechanism shell 511, contact pin mechanism inner core 512 and multiple
Contact pin 513；Contact pin mechanism shell 511 is set as barrel-like structure, and contact pin mechanism inner core 512 is set in contact pin mechanism shell 511
The middle part of chamber is simultaneously detachably connected with the inner wall of contact pin mechanism shell 511, and multiple contact pins 513 pass through pin machine in the vertical direction
Structure inner core 512.More preferably, contact pin mechanism inner core 512 and contact pin mechanism shell 511 are threadedly coupled or are clamped.
Further, contact pin mechanism shell 511 includes sequentially connected epimere 5111 and hypomere 5112, epimere 5111
