Description
Technical Field
The utility model belongs to the chest protection plate field of laryngoscope operation usefulness especially relates to a worm wheel lifting unit of chest protection plate of laryngoscope operation usefulness.
Background
In laryngoscope surgery, a breast plate assembly is used which serves to support the laryngoscope. The structure of chest protection plate component comprises a lifting shaft with the lower end connected with the side wall of the sickbed, and a tray connected in a rotating manner is arranged at the upper end of the lifting shaft. When the laryngoscope is used for surgery, a doctor firstly adjusts the height of the tray through the lifting shaft, then rotates the tray, suspends the tray above the chest of a patient by about 3-10cm, then fixes the laryngoscope on the tray, and finally performs surgery. The structure of telescopic shaft is equipped with the inner tube of being connected with the tray including being used for the person in charge of being connected with the sick bed in being responsible for, is equipped with the screw of being connected with the inner tube on being responsible for's the lateral wall, and the doctor can drag the inner tube after unscrewing the screw and reciprocate to the height of regulation tray. Because the tray is supported on the inner tube, the weight is large, and the doctor is led to waste labor in adjusting the height of the tray. The doctor is fixed in the tray with the laryngoscope to insert patient throat back with the laryngoscope, sometimes for convenient operation, still can continue fine adjustment tray height, but current telescopic shaft does not possess continuous and slight regulatory function, and the doctor probably need relapse a lot of experiments, and the inner tube height is removed to several times, dismantles the screw repeatedly, just can adjust the height of tray, and regulation efficiency is lower.
Therefore, the existing telescopic shaft for adjusting the height of the tray has the defects of labor waste and low adjusting efficiency.
SUMMERY OF THE UTILITY MODEL
An object of the utility model is to provide a chest protection plate worm wheel lifting unit. The utility model is used for tray altitude mixture control has laborsaving and the higher advantage of regulation efficiency.
The technical scheme of the utility model: the utility model provides a chest protection plate worm wheel lifting unit, is equipped with the screw rod including being responsible for, and the lower extreme of screw rod is equipped with the stopper of being connected with being responsible for, and the top of stopper is equipped with the nut of being connected with the screw rod, is equipped with the suit on the nut in the inner tube of screw rod, and the upper end of inner tube stretches out the person in charge, is equipped with the worm wheel of being connected with the screw rod between nut and the stopper, and one side of worm wheel is equipped with the worm, and the worm passes through the box and is connected with being.
In the above mentioned worm wheel lifting assembly for the breast protection plate, the outer side wall of the upper end of the nut is provided with a step embedded into the inner tube.
In the above-mentioned chest protection plate worm wheel lifting unit, be equipped with the transition lantern ring between being responsible for and the inner tube, the transition lantern ring is located the top of being responsible for.
In the above mentioned worm wheel lifting assembly for breast plate, a vertical chute is provided on the outer peripheral surface of the inner tube, and a sliding block connected with the main tube is provided in the chute.
Compared with the prior art, the utility model discloses regard as driver part with the handle, the handle passes through worm gear mechanism and drives the inner tube and goes up and down. Because the worm gear has good deceleration, the doctor can rotate the handle by a small force to drive the inner tube to lift and the tray connected with the inner tube to lift, so that the doctor can adjust the height of the tray in a labor-saving manner. The doctor is fixed in the tray with the laryngoscope to insert patient's throat back with the laryngoscope, if continue fine adjustment tray height, only need rotate the handle, and need not dismantle the screw repeatedly, improved regulation efficiency, and, under worm gear's deceleration, the handle rotates the round, and tray amplitude of rise is less, is favorable to the precision control of doctor to the tray height more.
Therefore, the utility model is used for tray altitude mixture control has laborsaving and the higher advantage of regulation efficiency.

Detailed Description
The following description is made with reference to the accompanying drawings and examples, but not to be construed as limiting the invention.
Examples are given. Chest protection plate worm wheel lifting unit, as shown in fig. 1, including being responsible for 1, be equipped with screw rod 2 in being responsible for 1, the lower extreme of screw rod 2 is equipped with the stopper 12 of being connected with being responsible for 1, the top of stopper 12 is equipped with the nut 3 of being connected with screw rod 2, be equipped with the suit on the nut 3 in the inner tube 4 of screw rod 2, the upper end of inner tube 4 stretches out and is responsible for 1, be equipped with the worm wheel 5 of being connected with screw rod 2 between nut 3 and the stopper 12, one side of worm wheel 5 is equipped with worm 6, worm 6 passes through box 7 and is connected with being responsible for 1, the one end of worm 6 stretches out box. The main pipe 1 penetrates through the box body 7, and an opening through which the worm 6 penetrates is formed in the main pipe 1.
