Detailed Description
In order that the utility model may be more readily understood, a more particular description of the utility model will be rendered by reference to specific embodiments that are illustrated in the appended drawings.
Referring to fig. 1 to 4, the present embodiment provides an insulating spacer for a driving assembly of an electric endoscope, which includes: the cylindrical body 2 is used for being sleeved outside the motor 3 in the driving assembly of the electric endoscope and coating the joint part of the reduction gearbox 4 and the motor 3 in the driving assembly, and the two axial ends of the cylindrical body 2 are both open ends. In this case, that is to say, the axial length of the overall cylindrical body 2 is greater than that of the motor 3, and in such a design, the connection part of the reduction gearbox 4 and the motor 3 is circumferentially surrounded by the cylindrical body 2, and even if part of grease leaks from the gap between the motor 3 and the reduction gearbox 4 during continuous use of the electric endoscope, the leaked grease can be prevented from directly leaking onto the inner wall of the handle housing 1 of the electric endoscope, so that the grease can be prevented from leaking onto the outer surface of the handle housing 1 because the insulation spacer covers the connection part of the reduction gearbox 4 and the motor 3 in the driving assembly.
Next, specifically, first, the cylindrical body 2 is made of an insulating material, which may be, for example, but not limited to, HDPE plastic material. With this structure, even when the cable 9 is broken to expose the electric wire, the insulating spacer can isolate the cable from the motor 3. The insulating isolation sleeve made of plastic material can be matched with the outer side wall of the motor 3 in an interference fit mode, so that the design of an assembly structure between the insulating isolation sleeve and the motor 3 is not needed, and the assembly process is simplified.
Furthermore, for guiding and fixing the cable 9 inside the electric endoscope, the outer side wall of the cylindrical body 2 adopted in the embodiment is provided with a plurality of parallel and spaced cards 5, and a clamping groove 6 for clamping the cable 9 is formed between every two adjacent cards 5. In combination with the generally conventional use of two cables 9, three cards 5 can be provided here, whereby two clamping grooves 6 are formed, each for clamping one cable 9. The card 5 here is optionally injection molded integrally with the tubular body 2.
Based on the above structure, further, in order to meet the requirement of the cable 9, the edge of the shaft end of the cylindrical body 2 far from the reduction gearbox 4 in the embodiment is provided with a plurality of protruding blocks 7, and a fixing groove 8 for fixing the cable 9 is formed between every two adjacent protruding blocks 7. Preferably, the plurality of projections 7 and the plurality of cards 5 are distributed along the axial direction of the cylindrical body 2. Under this kind of structure, the draw-in groove 6 that card 5 formed is mainly used for the spacing guide of cable 9 on the lateral wall of tube-shape body 2, and the fixed slot 8 that lug 7 formed is fixed at the axial end of tube-shape body 2 to cable 9 to through lug 7 and card 5 along the axial design of tube-shape body 2 distribution make holistic cable 9 can not appear buckling along the axial dimension of tube-shape body 2, thereby can reduce the probability that cable 9 appears damaging because of buckling.
In an alternative implementation case, the outer side wall of the cylindrical body 2 is provided with a plurality of reinforcing ribs 10 extending along the axial direction of the cylindrical body 2; and a plurality of reinforcing ribs 10 are provided at intervals in the circumferential direction. The use strength of the integral insulating isolation sleeve can be improved through the design of the reinforcing ribs 10, and deformation of the insulating isolation sleeve in the interference sleeving process with the motor 3 is prevented.
Finally, it is also necessary to state that, in an alternative embodiment, the edge of the tubular body 2 facing the shaft end of the reduction gearbox 4 is provided with a raised positioning block 11; and the positioning groove 12 for being in clamping fit with the positioning block 11 is formed on the outer side wall of the reduction gearbox 4, so that the integration of the coupling structure formed between the cylindrical body 2 and the reduction gearbox 4 and the motor 3 is stronger.
In summary, when the insulating spacer according to the present embodiment is applied to the driving assembly of the electric endoscope, the insulating spacer can play a role in isolating the cable from the motor 3 even when the cable 9 is damaged to expose the cable. Furthermore, even if some grease leaks from the gap between the motor 3 and the reduction gearbox 4 during the continuous use of the electric endoscope, for the leaked grease, the insulation isolation sleeve covers the connection part between the reduction gearbox 4 and the motor 3 in the driving assembly, so that the insulation isolation sleeve can form a stop for the leaked grease, so that the grease cannot directly leak onto the inner wall of the handle shell 1 of the electric endoscope, and the grease is prevented from leaking onto the outer surface of the handle shell 1. In addition, the clamping groove 6 for clamping and limiting the cable 9 is formed in the outer side wall of the insulating isolation sleeve, so that the cable 9 used in the electric endoscope can be effectively fixed and limited, and the problem that the cable 9 is damaged and exposed due to line crush caused by disordered distribution is solved.
In addition, in the operation process of the driving assembly of the electric endoscope, the motor 3 has certain vibration sense, and the insulation isolation sleeve is arranged between the motor 3 and the handle shell 1 of the electric endoscope, so that the isolation effect on the vibration sense caused by the operation of the motor 3 can be formed, and the vibration sense when a medical staff holds the handle shell 1 is reduced, thereby improving the comfort of operation and avoiding the influence of the vibration sense on the operation.
