Detailed Description

The following describes the embodiments of the present invention in further detail with reference to the accompanying drawings.

By figure 1 to 4 and give, axial and curved supporting seat 1 about including two, two supporting seats 1 are relative from top to bottom, curved driving groove 2 has been seted up to the coaxial in the supporting seat 1 of upside, the left and right sides rotates respectively in the driving groove 2 and is connected with axial band pulley 3 from top to bottom, two band pulleys 3 are connected through tooth belt 4, axial back shaft 5 about the 1 left and right sides of supporting seat of downside threaded connection respectively, two back shaft 5 upper ends run through supporting seat 1 and the coaxial transmission shaft 6 that is equipped with of downside respectively, two transmission shaft 6 upper ends insert respectively in driving groove 2 and rather than the coaxial fixed of band pulley 3 that corresponds the side, two transmission shafts 6 rotate respectively with the supporting seat 1 of upside and are connected.

In order to facilitate the use of the patient, the opposite sides of the two supporting seats 1 are respectively and coaxially provided with arc-shaped grooves 7 which are communicated left and right.

In order to move the belt wheel 3, a sliding groove 8 which is through from front to back is formed in the front side wall of the transmission groove 2, and a sliding block 9 with the front end extending out of the sliding groove 8 is arranged on the left side of the toothed belt 4.

In order to facilitate the movement of the belt wheel 3, the rear side wall of the transmission groove 2 is rotatably connected with a plurality of auxiliary wheels 10 which are uniformly distributed along the left-right direction, and the middle part of the transmission groove 2 is rotatably connected with a limiting wheel 14 which is meshed with the front side of the toothed belt 4.

In order to facilitate the examination of the laryngoscope, the opposite surfaces of the two supporting seats 1 are respectively provided with a rectangular groove 11 which is penetrated in the front and back direction.

In order to increase the sealing performance of the device, a dovetail groove with a forward opening is formed in the upper side wall of the sliding groove 8, an elastic cushion 12 is detachably connected in the sliding groove 8, and a dovetail block 13 capable of being inserted into the dovetail groove is arranged at the upper end of the elastic cushion 12.

When the utility model is used, the device is put into the mouth of a patient, so that the teeth at the upper side and the lower side of the patient are put into the arc-shaped grooves 7 at the corresponding sides, and the preparation stage is finished;

after the preparation stage is finished, the sliding block 9 slides rightwards, the sliding block 9 extrudes the elastic pad 12 upwards, meanwhile, the sliding block 9 drives the toothed belt 4 to rotate anticlockwise, the toothed belt 4 drives the two belt wheels 3 to rotate anticlockwise, meanwhile, the toothed belt 4 drives the limiting wheel 14 and the auxiliary wheel 10 to rotate, the two belt wheels 3 respectively drive the transmission shafts 6 on the corresponding sides of the two belt wheels to rotate anticlockwise, the two transmission shafts 6 respectively drive the support shafts 5 on the corresponding sides of the two belt wheels to rotate anticlockwise, as the support shafts 5 are in threaded connection with the support base 1 on the lower side, the two support shafts 5 push the support base 1 on the lower side to move downwards and prop open the oral cavity of a patient, as the sliding block 9 moves, when the oral cavity of the patient is expanded to a proper size, the sliding block 9 stops moving, and the elastic pad 12 is restored;

insert the laryngoscope position that the patient needs to inspect through rectangular channel 11, observe the patient's condition, if need relieve the support to patient's oral cavity, slide slider 9 left, slider 9 upwards extrudees cushion 12, slider 9 drives cog belt 4 clockwise rotation simultaneously, cog belt 4 drives two band pulleys 3 clockwise, two band pulleys 3 drive its transmission shaft 6 clockwise turning that corresponds the side respectively, two transmission shaft 6 drive its back shaft 5 clockwise turning that corresponds the side respectively, because back shaft 5 and the supporting seat 1 threaded connection of downside, along with the rotation of two back shaft 5, two back shaft 5 drive supporting seat 1 rebound of downside, along with the removal of slider 9, when two supporting seat 1 contact, stop moving slider 9, slider 9 resumes initial position and cushion 12 to the initial condition this moment.
