The invention has the advantages that: when the adjustable examination device for the ear-nose-throat department is used for examining a patient, the working process is as follows:

as shown in fig. 1, 2, 4 and 5, a patient is placed on the examination position 26, the corresponding examination part is adjusted to the examination position 26 according to the examination part of the patient, during adjustment, the motor 33 is started, the motor 33 drives the polygon bar 34 to rotate, the rotation of the polygon bar 34 synchronously drives the rotating shaft four 35 to rotate, the rotating shaft four 35 drives the gear wheel six 40 to rotate through the gear wheel seven 42, and at the moment, the gear wheel eight 43 is separated from the gear wheel five 39 without contact, so that the gear wheel six 40 drives the worm 32 to rotate through the rotating shaft five 41, further the worm 32 drives the worm wheel 31 to rotate, the rotation of the worm wheel 31 drives the gear wheel four 28 to rotate through the gear wheel three 29, so that the gear wheel four 28 drives the rotating shaft one 18 to rotate through the gear wheel two 9, further, the rotating shaft one 18 drives each extension accommodating mechanism to rotate through the hanger plate 16, and further the corresponding examination part on the extension accommodating mechanism is positioned on the guide plate 21, so as to use the inspection part carries out the inspection that corresponds to the disease on the inspection position 26 to be convenient for carry out the transposition adjustment to ear inspection part, nasal part inspection part, throat inspection part according to the sick position of disease, practical convenient reduces medical staff's intensity of labour, improves the practicality.

As shown in fig. 1, during the rotation of the first rotating shaft 18, each sliding rod 11 is synchronously driven to rotate by the circular plate 20, when the sliding rod 11 moves onto the guide plate 21 and moves upwards along the trend of the upper surface of the guide plate 21, the third connecting rod 14 applies an upward thrust to the corresponding first connecting rod 13, so that the first connecting rod 13 rotates around a hinge shaft of the first connecting rod and the fourth connecting rod 17, so that the first connecting rod 13 drives the corresponding inspection part to ascend through the mounting frame 12, the balls 19 play a role in reducing friction and noise, so that the extension accommodating mechanism works smoothly, when the balls 19 are positioned at the highest point of the guide plate 21, the first connecting rod 13 is in a horizontal state, the motor 33 stops working, so that the extension accommodating mechanism is unfolded and the inspection part is lifted to the highest point for taking the inspection part, and as the first connecting rod 13, the second connecting rod 15, the fourth connecting rod 17 and the mounting frame 12 form a parallel four-bar mechanism, therefore, the shape of the inspection component is not changed in the process of unfolding the stretching and accommodating mechanism, and the stable lifting of the inspection component is ensured.

When another inspection part needs to be used, the starting motor 33 drives the first rotating shaft 18 to rotate, the sliding rod 11 at the highest point of the guide plate 21 moves downwards, at the moment, a downward pressure is applied to the sliding rod 11 through the mounting frame 12, the first connecting rod 13 and the third connecting rod 14 under the self-weight action of the inspection part, so that the first connecting rod 13 rotates around the hinge shaft of the fourth connecting rod 17 in the opposite direction and resets, the first connecting rod 13 drives the corresponding inspection part to descend through the mounting frame 12 and reset, when the ball 19 is located on the upper surface of the cover plate 10, the inspection part is at the lowest position at the moment, and the stretching and containing mechanism is in a containing state, so that the occupied space is reduced, the management is facilitated, and the cleaning and maintenance of the inspection part are also facilitated.

As shown in fig. 1, 3 and 4, when the rising height of the examination part is found to be not suitable for use according to the physical characteristics or the examination part of the patient, the cylinder 36 is enabled to extend out of the piston rod by starting the cylinder 36, the collar 37 is enabled to drive the convex ring 38 and the rotating shaft four 35 to move to the right in fig. 4, the gear eight 43 is enabled to be meshed with the gear five 39, the gear seven 42 is enabled to be separated from the gear six 40 without contact, after the gear eight 43 is meshed with the gear five 39, the cylinder 36 stops working and keeps working, the motor 33 is enabled to work, the motor 33 is enabled to drive the rotating shaft four 35 to rotate by the multi-edge rod 34, so that the rotating shaft four 35 drives the gear five 39 to rotate by the gear eight 43, the gear five 39 drives the gear three 25 to rotate by the rotating shaft two 23, the rotation of the gear three 25 synchronously drives each gear one 5 to rotate by the tooth column 6, and further enables the gear one 5 to synchronously drive the corresponding screw rod 4 to rotate, make screw rod 4 rise or descend through screw drive ring frame 3, and then make ring frame 3 drive lifting column 7 in step and rise or will down, make lifting column 7 rise or descend through indexing mechanism and extension receiving mechanism drive inspection part, adjust to suitable height, so as to the more suitable use of inspection part, reduce medical staff intensity of labour, and can carry out the adaptability according to the physical characteristics of disease or inspection part to inspection part height and adjust, adopt independent indexing mechanism, elevating system driven mode, the transposition adjustment to inspection part that can make things convenient for the accuracy, the altitude mixture control carries out steady drive, can not receive the interference each other.

It will be evident to those skilled in the art that the invention is not limited to the details of the foregoing illustrative embodiments, and that the present invention may be embodied in other specific forms without departing from the spirit or essential attributes thereof. The present embodiments are therefore to be considered in all respects as illustrative and not restrictive, the scope of the invention being indicated by the appended claims rather than by the foregoing description, and all changes which come within the meaning and range of equivalency of the claims are therefore intended to be embraced therein. Any reference sign in a claim should not be construed as limiting the claim concerned.

In the description of the present invention, "a plurality" means two or more unless otherwise specified; the terms "upper", "lower", "left", "right", "inner", "outer", "front", "rear", "head", "tail", and the like, indicate orientations or positional relationships based on the orientations or positional relationships shown in the drawings, are only for convenience in describing and simplifying the description, and do not indicate or imply that the device or element referred to must have a particular orientation, be constructed in a particular orientation, and be operated, and thus, should not be construed as limiting the invention. Furthermore, the terms "first," "second," "third," and the like are used for descriptive purposes only and are not to be construed as indicating or implying relative importance.
