The technical scheme in the invention for solving the above technical problem is: should, for regulating the translation geared assembly of laryngoscope to comprise handle, it is characterized in that: be also provided with translational adjustment assembly, screw rod and bevel gear two; Described translational adjustment assembly comprises power transmission shaft, holder, bevel gear one and forward and backward pad; Described handle and power transmission shaft are fixed, and power transmission shaft and bevel gear one are fixing; Described front pad is between bevel gear one and holder, and rear pad is between handle and holder; Described power transmission shaft and bevel gear one are sleeved in holder; Described bevel gear two is connected with screw rod, and bevel gear one and bevel gear two engagements.Make translational adjustment convenient, and can stablize self-locking, can be positioned at any position.
Handle described in the utility model comprises handwheel and hand wheel handle, and they interfix.
Handwheel described in the utility model and power transmission shaft are fixed by pin, and power transmission shaft and bevel gear one are fixed by screw.Make structure more rationally simple, easy to operate; Easily power is passed to bevel gear one from hand wheel handle, during adjusting, handle is stable, and in operation process, handling safety is reliable.
Handwheel described in the utility model, holder, bevel gear one are arranged in the outer surface of power transmission shaft successively.Make transmission convenient and reliable.
This utility model compared with prior art, have the following advantages and effect: structural design is more reasonable, by coordinating of this utility model and handle main body in laryngoscope, can realize moving horizontally of index glass sheet, in operation on larynx, use convenient, reliable and safety, the resultant effect of operation is better.
Accompanying drawing explanation
Fig. 1 is for being used the structural representation of this utility model laryngoscope.
Fig. 2 is the structural representation cutaway view of A-A in Fig. 1.
Fig. 3 is the structural representation cutaway view of Fig. 1.
Fig. 4 is structural representation of the present utility model.
The specific embodiment
Referring to Fig. 1-Fig. 4, use laryngoscope of the present utility model mainly by handle main body 1, translational adjustment assembly 2, rotation adjusting part 3, apparatus gatherer 4, horizontal glass sheet 5 and index glass sheet 6, to be formed.Handle main body 1 is fixing with horizontal glass sheet 5, and translational adjustment assembly 2 is fixing by screw and handle main body 1, and one end of rotation adjusting part 3 is positioned at handle main body 1, and apparatus gatherer 4 is fixing with index glass sheet 6.Handle main body 1 comprises body 11, index glass bar 13, screw rod 14, bevel gear 2 15 and back-up ring 16; Index glass bar 13 is fixed and is connected with index glass plate rack 12 by bearing pin with screw rod 14 by pin, and bevel gear 2 15 is connected with screw rod 14 and is limited in handle body 1 by back-up ring 16, and back-up ring 16 is fixed by a pin in body 11.
This utility model comprises translational adjustment assembly 2, screw rod 14 and bevel gear 2 15; Wherein: translational adjustment assembly 2 comprises the handwheel 21 that interfixes and hand wheel handle 22 and power transmission shaft 23, holder 24, bevel gear 1 and front pad 26, rear pad 27; Handwheel 21 is fixed by pin with power transmission shaft 23, and power transmission shaft 23 is fixed by screw with bevel gear 1, and power is passed to bevel gear 1 from hand wheel handle 22; Front pad 26 is between bevel gear 1 and holder 24, and rear pad 27 is between handwheel 21 and holder 24, and holder 24 is fixed by screws in handle main body 1; Handwheel 21, holder 24, bevel gear 1 are arranged in the outer surface of power transmission shaft 23 successively; This bevel gear 1 and bevel gear 2 15 engagements.
