Detailed Description
The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.
Referring to fig. 1-4, the present invention provides an embodiment:
the utility model provides a spacing subassembly of oral cavity spread support ware, includes grab handle 1, curb plate 2, adjusts and props 3 and fixed 4 that prop, the left side on grab handle 1 top is provided with fixedly and props 4, fixedly prop 4 go up the articulated regulation that is connected with and prop 3, the fixed 1 top vertical curb plate 2 that is provided with of grab handle that props 4 backs, sliding arc 6 has been seted up on curb plate 2, the right-hand member that 3 backs were propped in the regulation is provided with sliding block 7, just sliding block 7 slidable mounting is in sliding arc 6.
Referring to fig. 1 and 2, the right end of the front surface of the adjusting support 3 is provided with an adjusting rod 5, and the medical staff can push the adjusting rod 5 to adjust the angle between the adjusting support 3 and the fixing support 4 by holding the grip handle 1 and using the thumb. The top of sliding block 7 is provided with first extension piece 11, draw-in groove 14 has been seted up to one side that first extension piece 11 is close to curb plate 2, curb plate 2 has evenly been seted up along the outside of slip arc 6 on one side that is close to first extension piece 11 and has been blocked ball groove 8, all install reset spring 15 in the card ball groove 8, reset spring 15 is close to the one end of first extension piece 11 and all is provided with spacing calorie of ball 9, spacing calorie of ball 9 is the arc near the one end of first extension piece 11, spacing calorie of ball 9 mutually supports with draw-in groove 14, has constituteed buckle structure.
In the process that the adjusting rod 5 is pushed upwards, the sliding block 7 on the back of the adjusting support 3 slides in the sliding arc 6, at the moment, the right end of the limiting blocking ball 9 is squeezed, as the right end of the limiting blocking ball 9 is arc-shaped, the limiting blocking ball 9 can move towards the inner side of the blocking ball groove 8 when being squeezed by enough force, so that the limiting blocking ball 9 can be separated from the clamping groove 14, the clamping structure formed by the clamping groove 14 and the limiting blocking ball 9 can be released, when the sliding block 7 is pushed upwards continuously, the next limiting blocking ball 9 can be clamped into the clamping groove 14 for fixing, when the angle supported by the adjusting support 3 and the fixed support 4 is pushed to be enough for observing the angle of the oral cavity of a patient, a medical worker can slowly put down the thumb downwards, the oral cavity can be slightly closed, so that the angle between the adjusting support 3 and the fixed support 4 is reduced, similarly, the sliding block 7 can slide downwards, and the clamping groove 14 can be squeezed into the lower limiting blocking ball 9, avoid the discomfort of the patient caused by the overlarge expansion.
Fixed slot 10 has all been seted up on the curb plate 2 of sliding arc 6 one side is kept away from in card ball groove 8, the one end that sliding block 7 was kept away from to first extension piece 11 is provided with second extension piece 12, transversely insert spacing rod 17 on the second extension piece 12, the one end that curb plate 2 was kept away from to spacing rod 17 is provided with press plate 13, the one end that curb plate 2 was close to spacing rod 17 is provided with adsorption magnet 16, the inside of fixed slot 10 all is embedded to have the iron sheet, adsorption magnet 16 has constituteed adsorption structure with the iron sheet. Through pushing away the pressing plate 13 to the left side, make the absorption magnet 16 card of gag lever post 17 left end carry on spacingly in going into fixed slot 10, the patient can't adjust by oneself this moment again and prop 3 and fixed angle of propping 4 props, and the iron sheet in absorption magnet 16 and the fixed slot 10 adsorbs, has also avoided absorption magnet 16 to break away from fixed slot 10.
A limiting baffle 18 is arranged at one end of the limiting rod 17 close to the adsorption magnet 16, and the limiting baffle 18 and the pressing plate 13 also have a limiting effect, so that the limiting rod 17 is prevented from being pulled down from the second extension block 12.
The working principle is as follows: when in use, the medical staff holds the grab handle 1, then the left ends of the fixed support 4 and the adjustable support 3 extend into the oral cavity of a patient, the medical staff pushes the adjusting rod 5 upwards by a thumb, so that the right end of the adjustable support 3 rises, the distance between the left ends of the adjustable support 3 and the fixed support 4 is enlarged, the oral cavity of the patient is enlarged, meanwhile, in the process that the adjusting rod 5 is pushed upwards, the sliding block 7 at the back of the adjustable support 3 slides in the sliding arc 6, refer to the attached drawings 2 and 4, at the moment, the right end of the limiting clamping ball 9 is extruded, and because the right end of the limiting clamping ball 9 is arc-shaped, the limiting clamping ball 9 can move towards the inner side of the clamping ball groove 8 when being extruded by enough force, so that the limiting clamping ball 9 can be separated from the clamping groove 14, the clamping structure formed by the clamping groove 14 and the limiting clamping ball 9 can be released, and.
The next limiting blocking ball 9 can be clamped into the blocking groove 14 for fixing, when the angle of the supporting angle of the support 3 and the fixed support 4 is enough for observing the angle of the oral cavity of a patient, medical staff can put down the thumb downwards slowly, the oral cavity of the patient can be closed slightly, so that the angle between the support 3 and the fixed support 4 is reduced, and similarly, the sliding block 7 can slide downwards, the blocking groove 14 can be extruded into the lower limiting blocking ball 9, and the discomfort caused by the patient due to the overlarge supporting expansion is avoided.
Then, the staff makes the absorption magnet 16 card of gag lever post 17 left end carry on spacingly in the fixed slot 10 through promoting the pressure board 13 to the left side, and the patient can't adjust by oneself again at this moment and adjust the angle that props 3 and fixed 4 props and prop up, and the iron sheet in absorption magnet 16 and the fixed slot 10 adsorbs, has also avoided absorption magnet 16 to break away from in the fixed slot 10, and limit baffle 18 has also played spacing effect with pressure board 13, avoids gag lever post 17 to be taken out from second extension piece 12.
It is obvious to a person skilled in the art that the invention is not restricted to details of the above-described exemplary embodiments, but that it can be implemented in other specific forms without departing from the spirit or essential characteristics of the invention. 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.
