referring to fig. 5, two wiping rollers 8 are rotatably arranged on one of the wiping frames 5 at intervals longitudinally, cotton cloth 9 (shown in fig. 8) is wound around the bottom of the wiping frame 5 between the two wiping rollers 8, one wiping roller 8 is wound with clean and to-be-used cotton cloth 9, the other wiping roller 8 is used for collecting used cotton cloth 9, referring to fig. 7, one wiping roller 8 (namely, the one wiping roller 8 used for collecting used cotton cloth 9) is connected with a direction adjusting device arranged on the wiping frame 5 through a wiping transmission device, the direction adjusting device is connected with a wiping gear 10 rotatably arranged on the wiping frame 5, the wiping gear 10 is meshed with a wiping rack 11 fixedly arranged on one cantilever of the U-shaped frames 4, and when the wiping frame 5 moves along the cantilever of the U-shaped frame 4 under the driving of a reciprocating transmission device, the wiping rack 11 is used for driving the wiping gear 10 to rotate and adjusting the direction of the wiping gear by the direction adjusting device (namely, the wiping rack 5 is enabled to drive one of the wiping rollers 8 to always rotate towards the same direction by the direction adjusting device in the process of reciprocating along the cantilever of the U-shaped rack 4, and the wiping gear 10 is inevitably subjected to periodic reciprocating forward and backward rotation in the process of reciprocating the wiping rack 5), so that the wiping roller 8 which is driven by the wiping gear and used for collecting the used cotton cloth 9 is always driven to rotate towards the same direction, and the effect of collecting and winding the used cotton cloth 9 on the wiping roller 8 is achieved;

referring to fig. 1, the device is initially installed at a position where the U-shaped frame 4 is rotatably installed with the semi-cylinder 2 and the protection cylinder 1, the end of the U-shaped frame 4 away from the telescopic shaft 3 is away from the position where the patient needs to be examined (such as abdomen, chest, etc.), when the device is used, a doctor first places the device at a position where the patient needs to be examined (such as abdomen, chest, etc.) and makes the lower end surface of the suction cup 75 contact with the position where the patient needs to be examined, then presses the protection cylinder 1 downwards with force to discharge the air inside the suction cup 75 outwards, at the same time, positions the protection cylinder 1 at the position where the patient needs to be examined under the action of atmospheric pressure, and sets the telescopic shaft 3 rotatably installed on the semi-cylinder 2 to be in a compressed state when we press the protection cylinder 1 downwards with force and make the air inside the suction cups 75 discharge outwards (refer to fig. 5, that is, at this time, the bottom of the wiping frame 5 with the wiping roller 8 installed at the same ) When the disinfection device is used specifically, a doctor firstly enables a storage barrel containing disinfection solution to pour the disinfection solution downwards by controlling an electric valve arranged at the bottom of the storage barrel, the electric valve is closed after a certain amount of disinfection solution is poured, then the doctor starts a motor (not shown in the figure, the doctor can use a micro motor, because a large force is not needed when wiping a part to be inspected of a patient), referring to the attached drawing 5, the motor is started to drive the incomplete gear 12 to rotate (initially, the upper end surface of the sector gear 13 vertically and slidably arranged with the incomplete gear 12 is as high as the upper end surface of the incomplete gear 12, namely, the upper end surface and the upper end surface are matched to form a complete gear), the complete gear is driven by the complete gear formed by the incomplete gear 12 and the sector gear 13 to drive the rotating gear 15 meshed with the incomplete gear to rotate along with the starting of the motor, and the rotating gear 15 is fixedly sleeved at the upper end of the telescopic shaft 3 to, with the rotation of telescopic shaft 3 and then drive U-shaped frame 4 and rotate in the circular cylinder that half cylinder 2 and protective barrel 1 are constituteed, when U-shaped frame 4 rotated, rotate and install two drive one-way gear 6 and the ring gear 7 corresponding with it that U-shaped frame 4 kept away from telescopic shaft 3 one end and vertical interval set up and mesh in U-shaped frame 4, we set for: at the moment, only the driving one-way gear 6 corresponding to the wiping rack 5 provided with the wiping roller 8 can drive the wiping rack 5 to reciprocate along the cantilever of the U-shaped rack 4 through the reciprocating transmission device along with the rotation of the U-shaped rack 4, and under the meshing action of the other driving one-way gear 6 and the inner gear ring 7 matched with the other driving one-way gear, the other driving one-way gear can only idle and can not transmit power to the corresponding reciprocating transmission device (at the moment, the wiping rack 5 can not move along the cantilever of the U-shaped rack 4, namely, the two driving one-way gears 6 can only realize the effect of driving the reciprocating transmission device to act when being meshed with the inner gear ring 7 at the lower part, the direction of the motor for driving the U-shaped rack to rotate is certain, when the U-shaped rack rotates for half a circle, the driving one-way gear at the upper part rotates 180 degrees to the lower part and the driving one-way gear 6 at, when the power transmission device is arranged, the driving one-way gear 6 is matched with the inner gear ring and performs power transmission when being positioned at the lower part, and when the driving one-way gear 6 rotates to the upper part by turning 180 degrees, the driving one-way gear 6 cannot realize power transmission);

so, 4 along semicylinder 2 at U-shaped frame, when circular motion is done in the circular cylinder that protective barrel 1 constitutes (i.e. make antiseptic solution along semicylinder 2, protective barrel 1's periphery evenly paints), make in step that install wiping jig 5 of wiping roller 8 carry out reciprocating motion along U-shaped frame 4 cantilever (i.e. make the disinfection along protective barrel 1, the circular cylinder that semicircular barrel 2 constitutes radially evenly paints), and then will empty the antiseptic solution that will examine the position at the patient and at protective barrel 1, the regional effect of evenly painting that encloses of semicircular barrel 2, it is here that need notice: referring to fig. 7, when the wiping frame 5 with the wiping rollers 8 mounted thereon reciprocates along the cantilever of the U-shaped frame 4, the direction adjusting device is further driven by the wiping rack 11 and the wiping gear 10, and the wiping roller 8 for collecting the used cotton cloth 9 is driven to rotate by the direction adjusting device, during the process that the U-shaped frame 4 drives the wiping frame 5 to uniformly apply the disinfectant, the cotton cloth 9 wound on the two wiping rollers 8 and bypassing the bottom wall of the wiping frame 5 directly contacts with the part to be inspected of the patient and uniformly applies the disinfectant (as shown in fig. 8), so that the unused cotton cloth 9 wound on the wiping rollers 8 bypasses the bottom wall of the wiping frame 5 and is finally wound on the wiping rollers 8 for collecting (during the process that the cotton cloth 9 is transferred from one wiping roller 8 to the other wiping roller 8, uniform application of the disinfectant is realized during the process that the wiping frame 5 with the wiping rollers 8 mounted thereon moves along the cantilever of the U-shaped frame 4 (as shown in fig. 8) Level application), care should be taken here to: when the cotton cloth 9 is transferred from one wiping roller 8 to the other wiping roller 8, the effect of uniformly wiping the disinfectant is realized at the early stage, and the effect of wiping the disinfectant uniformly smeared on the part to be inspected of the patient is realized through the cotton cloth 9 at the later stage, so that the part to be inspected of the patient is kept in a relatively clean state before the couplant is smeared;

referring to fig. 12, in the process that the motor drives the rotating gear 15 to rotate through the incomplete gear 12, the rotating gear 15 drives the intermittent transmission device connected with the rotating gear 15 to act through the telescopic shaft 3, as shown in fig. 15, the intermittent transmission device drives the lifting rod 16 slidably mounted on the semi-cylinder 2 to move towards the direction close to the lifting device, that is, the rotating gear 15 drives the lifting rod 16 to move a certain distance towards the direction close to the lifting device through the intermittent transmission device every rotation circle (we set that the lifting rod 16 and the lifting device are in the mutually abutting state at the initial time, as shown in fig. 14, and at the moment, the sector gear 13 is just in the state of being meshed with the rotating gear 15, the motor starts to drive the incomplete gear 12 to rotate along the counterclockwise direction as shown in fig. 14), and when the lifting rod 16 moves towards the lifting device, the effect of driving the lifting device to move upwards for a certain distance is synchronously realized (when the incomplete gear moves towards the lifting device 12 drive the sector gear 13 to rotate and no longer contact with the jacking device, the sector gear 13 is reset under the action of the reset spring 14, as shown in fig. 13, a schematic connection relationship between the sector gear 13 and the stub gear 12 is shown, that is, the upper end surface of the sector gear 13 and the upper end surface of the stub gear 12 are leveled again, so that when the stub gear 12 drives the sector gear 13 to move again to contact with the jacking device, the jacking device is raised by a certain height and the vertical displacement of the sector gear 13 relative to the stub gear 12 is larger at this time, that is, when the stub gear 12 rotates for one circle, the jacking device moves upward for a certain distance, so that when the stub gear 12 drives the sector gear 13 to move again to contact with the jacking device and at this time, the lower end surface of the sector gear 13 is just higher than the upper end surface of the stub gear 12 under the action of the jacking device (at this time, the sector gear 13 and the rotating gear 15 are no longer in the same plane range, that is, the sector gear 13 and the rotating gear 15 are not overlapped in the vertical direction, and we set that at the beginning, the sector gear 13 and the jacking device are in a contact state and there is no interaction force between the jacking device and the sector gear 13 at this time, the motor just drives the incomplete gear 12 to rotate N full turns (so that the U-shaped frame 4 rotates N full turns in the circular cylinder formed by the protective cylinder 1 and the semi-circular cylinder 2), at this time, the sector gear 13 just rotates with the incomplete gear 12 to a position to be engaged with the turning gear 18 (the turning gear 18 is identical to the rotating gear 15 in size and number of teeth), and along with the continuous rotation of the motor, the incomplete gear 12 continues to rotate along the counterclockwise direction as in fig. 14 (at this time, the notch position on the incomplete gear 12 corresponds to the rotating gear 15 and at this time, the incomplete gear 12 cannot drive the rotating gear 15 to rotate, at this time, the U-shaped rack 4 is in a stopped state and the U-shaped rack 4 is at an initial position), at the same time, the incomplete gear 12 starts to engage with the direction-adjusting gear 18 and drives the U-shaped rack 4 to rotate through the direction-adjusting gear 18 and the direction-adjusting transmission device, so that when the sector gear 13 is separated from the direction-adjusting gear 18, the U-shaped rack 4 is just driven to rotate for a half circle (i.e., the wiping rack 5 with the wiping roller 8 mounted thereon is rotated to the upper side and the wiping rack 5 without the wiping roller 8 mounted thereon is moved to the lower side), and at this time, the teeth on the incomplete gear 12 just need to engage with the rotating gear 15 (the notch position on the incomplete gear 12 just completely passes over the rotating gear 15), and when the incomplete gear 12 is again engaged with the rotating gear 15, the telescopic shaft 3 starts to rotate again to synchronously drive the U-shaped rack 4 to rotate (at this time, the doctor opens the electric valve corresponding to the storage cylinder with the couplant and controls the storage cylinder The agent is poured to the part to be inspected of the patient), after the sector gear 13 is disengaged from the direction-adjusting gear 18 and the sector gear 13 is continuously rotated for a certain angle along with the incomplete gear 12, the sector gear 13 can be disengaged from the jacking device, and then the sector gear 13 is restored to the initial position under the action of the return spring 14 (namely, the upper end surface of the sector gear 13 is flush with the upper end surface of the incomplete gear 12 and is restored to the position shown in the attached figure 14), in the process that the motor continues to drive the telescopic shaft 3 to rotate through the incomplete gear 12, the telescopic shaft 3 drives the intermittent transmission device connected with the telescopic shaft 3 to realize the contact separation with the jacking rod 16 (namely, at the moment, the telescopic shaft 3 cannot drive the jacking rod 16 to move towards the direction close to the jacking device through the intermittent transmission device, and at the moment, the jacking rod 16 is not subjected to the acting force from the intermittent transmission device any more, so that the jacking rod 16 moves towards the initial position under the action of the jacking spring 17 and completes the reset);

after that, under the driving of the motor, the wiping frame 5 without the wiping roller 8 is used to achieve the effect of smearing the couplant poured to the part to be inspected of the patient, and the smearing manner of the couplant by the wiping frame 5 without the wiping roller 8 is the same as the smearing manner of the disinfectant by the wiping frame 5 with the wiping roller 8 (which has already been described above and will not be described in detail here), we set that, when the motor drives the sector gear 13 to rotate again in the counterclockwise direction shown in fig. 14 to the position to be engaged with the rotating gear 15 (i.e., when the positional relationship between the sector gear 13 and the rotating gear 15 is in the initial state), the motor stops rotating after the motor drives the telescopic shaft 3 to rotate again for N full circles from this moment (we electrically connect the motor controller with the microcontroller to achieve the control of the start and stop time of the motor, namely, the motor drives the telescopic shaft 3 to rotate for 2N +1 circles in the process from the start operation to the final stop operation, and at this point the sector gear 13 is again in the position to be engaged with the steering gear 18, as shown with reference to figure 4, when the motor stops working, the semi-cylinder 2 is rotated to open the circular cylinder part consisting of the protective cylinder 1 and the semi-cylinder 2 (a gap is generated at the moment), a doctor can place a probe for ultrasonic detection on the part to be detected of a patient through the gap and realize ultrasonic detection on the part of the patient coated with the coupling agent, at the moment, the doctor can only move the ultrasonic detection probe within the range of the protective cylinder 1, the situation that the couplant is diffused to the part which does not need to be checked due to the fact that the ultrasonic probe needs to be moved continuously in the detection process can be avoided well, and unnecessary troubles are avoided for subsequent cleaning work;

preferably, we can be with microcontroller and the electric valve of installing in two storage barrel bottoms and the discharge mechanism electric connection of setting in depositing couplant storage barrel, before the device put into operation, all can set for corresponding time parameter through microcontroller and can realize opening and closing time and the start-up and the stop time of discharge mechanism of controlling two electric valve through microcontroller.

Embodiment 2, on the basis of embodiment 1, referring to fig. 13, we fix an arc plate 19 vertically spaced from the bottom wall of the incomplete gear 12, referring to fig. 12, the jacking device includes an arc ramp 20 vertically slidably mounted on the semi-cylindrical barrel 2 and cooperating with the arc plate 19, the arc ramp 20 is coaxially disposed with the incomplete gear 12, and a telescopic spring 21 is connected between the arc ramp 20 and the semi-cylindrical barrel 2 (initially, the lower end surface of the arc plate 19 and the upper end surface of the arc ramp 20 contact each other, but there is no interaction force therebetween), referring to fig. 14, we fix an interference plate 22 cooperating with the jacking rod 16 on the lower end surface of the arc ramp 20, and initially, the interference plate 22 and the jacking rod 16 are in a contact state, we set the contact portion between the jacking rod 16 and the contact plate 22 to be arc, so that when the jacking rod 16 is driven by the intermittent transmission device, the abutting plate 22 connected with the arc-shaped ramp 20 can be lifted upwards through the arc-shaped surfaces of the contact parts of the arc-shaped ramp and the arc-shaped ramp 20, so that the arc-shaped ramp 20 is driven to move upwards, and the sector gear 13 vertically and slidably mounted with the incomplete gear 12 synchronously moves upwards along with the upward movement of the arc-shaped ramp 20 (so that the reset spring 14 between the sector gear 13 and the incomplete gear 12 is stretched to store energy);

that is, each rotation of the telescopic shaft 3 drives the lifting rod 16 to move a certain distance towards the direction close to the contact plate 22, and further the arc-shaped ramp 20 moves upwards a certain distance, so that when the incomplete gear 12 drives the sector gear 13 to rotate along the counterclockwise direction shown in fig. 14 to a position above the arc-shaped ramp 20, the distance that the sector gear 13 moves upwards can be further increased, when the incomplete gear 12 drives the arc-shaped plate 19 fixedly installed at the bottom of the sector gear 13 to contact one side of the arc-shaped ramp 20, the sector gear 13 is forced to move upwards under the action of the arc-shaped ramp 20, so that when the lower end surface of the arc-shaped plate 19 contacts with the horizontal position of the upper end surface of the arc-shaped ramp 20, the sector gear 13 does not move upwards any more and rotates counterclockwise with the incomplete gear 12, so that the horizontal position of the upper end surface of the arc-shaped ramp 20 is separated from the lower end surface of the arc-shaped plate 19, the sector gear 13 can only be reset under the action of the return spring 14 (we set that the teeth on the sector gear 13 are already no longer meshed with the rotary gear 15 but the teeth on the stub gear 12 carry the rotary gear 15).

Embodiment 3, on the basis of embodiment 2, referring to fig. 15, we have a plurality of driving tooth systems 23 at one end of the lifting rod 16 away from the touch plate 22, and the driving tooth systems 23 are engaged with an incomplete gear 24 rotatably mounted on the semi-cylinder 2 (i.e., a part of the outer circumferential surface of the gear is not provided with tooth systems, as shown in fig. 15), the intermittent transmission device includes a sheave 25 coaxially rotating with the incomplete gear 24, and the sheave 25 is matched with a driving wheel 26 fixedly sleeved on the telescopic shaft 3 (the sheave 25 is matched with the driving wheel 26 to realize intermittent transmission, which is the prior art and widely used, and the above transmission mode can be easily obtained by those skilled in the art when in setting, so that the transmission principle of the two will not be described in detail herein, referring to fig. 15, we have four grooves on the sheave 25, so that each rotation of the driving wheel 26 can realize a quarter-turn of the sheave 25, that is, each time the telescopic shaft 3 rotates one turn, the incomplete gear 24 can be driven to rotate one quarter turn (the part of one quarter turn on the outer circumferential surface of the incomplete gear 24 is not provided with a tooth system), we set that initially, the tooth system of the outer circumferential surface of three quarters of the incomplete gear 24 is not meshed with the driving tooth system 23 on the lifting rod 16, when the motor is started to drive the telescopic shaft 3 to rotate and further drive the incomplete gear 24 to rotate through the driving wheel 26 and the sheave 25 which are matched with each other, the tooth system on the incomplete gear 24 is meshed with the driving tooth system 23 on the lifting rod 16 so as to drive the lifting rod 16 to move in the direction of exceeding the extrusion abutting plate 22 (so that the lifting spring 17 connected between the lifting rod 16 and the semi-cylinder 2 is compressed), so that the rotation is stopped after the incomplete gear 24 rotates one quarter turn, at this time, the lifting rod 16 and the plate 22 are matched with each other to drive the arc-shaped ramp 20 to move upwards for a certain distance, because the number of rotation turns of the telescopic shaft 3 is synchronous with the incomplete gear 12 (the radius of the incomplete gear 12, the rotating gear 15 and the direction-adjusting gear 18 are set to be the same), when the arc-shaped ramp 20 moves upwards for a certain distance and stops moving, the incomplete gear 12 just drives the arc-shaped plate 19 fixedly connected with the sector gear 13 to rotate to a contact part with one side of the arc-shaped ramp 20, and the sector gear 13 moves upwards for a certain distance under the action of the arc-shaped ramp 20 along with the continuous rotation of the incomplete gear 12, so that after the arc-shaped plate 19 is separated from the upper end surface of the arc-shaped ramp 20, the sector gear 13 is reset under the action of the reset spring 14, and when the arc-shaped plate 19 is completely separated from the arc-shaped ramp 20, the driving wheel 26 drives the grooved pulley 25 to rotate again and the sector gear 13 rotates again to make the arc-shaped plate 19 contact with one side of the arc-shaped ramp 20, the driving wheel 26 drives the arc-shaped ramp 20 to move upwards for a certain distance again through the grooved wheel 25;

because the grooved pulley 25 is provided with four grooves, one rotation of the driving wheel 26 drives the grooved pulley 25 to rotate a quarter of a turn, that is, when the grooved pulley 25 drives the tooth system on the incomplete gear 24 to just separate from the driving tooth system 23 on the jacking rod 16 (at this time, the incomplete gear 24 rotates three quarters of a turn, that is, the driving wheel 26 and the telescopic shaft 3 rotate three turns), at this time, the arc-shaped ramp 20 moves upwards to the maximum distance and at this time, under the action of the arc-shaped plate 19 and the arc-shaped ramp 20 which are matched with each other, the lower end surface of the sector gear 13 is just higher than the upper end surface of the incomplete gear 12 (at this time, the sector gear 13 just vertically overlaps with the steering gear 18), at this time, although the sector gear 13 rotates to the position where the sector gear 15 will be meshed with the rotary gear, because the sector gear 13 does not vertically overlap with the rotary gear 15, at this time, at the moment, the sector gear 13 just meshes with the direction-adjusting gear 18 and drives the direction-adjusting gear 18 to rotate (in the process, the notch position on the incomplete gear 12 is matched with the rotating gear 15, but the rotating gear 15 cannot be driven), when the sector gear 13 is separated from the direction-adjusting gear 18 along with the continuous rotation of the incomplete gear 12, the direction-adjusting gear 18 stops rotating and drives the U-shaped frame 4 to rotate for half a circle through the direction-adjusting transmission device connected with the direction-adjusting gear (namely, after the U-shaped frame 4 rotates 180 degrees, the two wiping frames 5 are exchanged in position), the separation of the sector gear 13 and the direction-adjusting gear 18 is set to occur before the arc-shaped plate 19 is separated from the arc-shaped ramp 20, namely, after the U-shaped frame 4 rotates for half a circle, the lower end face of the arc-shaped plate 19 is separated from the upper end face of the arc-shaped ramp along with the continuous rotation direction of the incomplete gear 12 (the sector gear 13 is, and then the driving wheel 26 drives the incomplete gear 24 to rotate through the grooved wheel 25 (at this time, the tooth system on the incomplete gear 24 is completely separated from the driving tooth system 23, at this time, the circumferential surface provided with the tooth system on the incomplete gear 24 corresponds to the driving tooth system 23, at this time, the driving tooth system 23 is not subjected to the meshing acting force of the incomplete gear 24, so that the jacking rod 16 moves towards the initial position under the action of the jacking spring 17 and completes the resetting);

during the period that the incomplete gear 24 stops rotating, a locking device for locking the incomplete gear 24 is provided, so that when the driving wheel 26 is disengaged from the sheave 25, the incomplete gear 24 can be kept in the current state and the jacking rod 16 cannot move due to the action force of the jacking spring 17, referring to fig. 16, a locking column 28 is vertically and slidably mounted on the semi-cylinder 2, a locking spring 29 is connected between the locking column 28 and the semi-cylinder 2, four locking holes 27 are formed in the lower end face of the incomplete gear 24 at equal intervals in a surrounding manner, so that the locking column 28 can be inserted into the locking hole 27 under the action of the locking spring 29 to achieve the locking effect on the incomplete gear 24, namely, the locking column 28 can be inserted into the locking hole 27 arranged on the lower end face of the incomplete gear 24 to achieve the locking on the incomplete gear 24 each time the driving wheel 26 is disengaged from the sheave 25, namely, after the lifting rod 16 moves forward for a certain distance, the lifting rod can be kept at the current position (the elastic coefficient of the locking spring 29 set by us is larger than that of the lifting spring 17, namely, the elastic force of the lifting spring 17 on the lifting rod 16 can be overcome through the cooperation of the locking column 28 and the locking hole 27, and the lifting rod 16 is stably kept at the current position), the chamfering setting is carried out at the end, inserted into the locking hole 27, of the locking column 28, so that when the incomplete gear 24 is driven by the grooved wheel 25, the locking column 28 can be forced to exit the locking hole 27 downwards, and the grooved wheel 25 is not prevented from driving the incomplete gear 24 to rotate;

preferably, in order to avoid the rotation of the telescopic shaft 3 in the process that the sector gear 13 is engaged with the direction-adjusting gear 18 and drives the U-shaped frame 4 to rotate, the locking rod 72 is vertically slidably mounted on the semi-cylinder 2, the locking spring 73 is connected between the locking rod 72 and the semi-cylinder 2, the locking hole 74 matched with the locking rod 72 is arranged at the upper end of the telescopic shaft 3, namely, when the telescopic shaft 3 rotates for one circle, the locking rod 72 can be inserted into the locking hole 74 under the action of the locking spring 73, when the locking hole 74 rotates to the position corresponding to the locking rod 72 in the continuous rotation process of the telescopic shaft 3, the locking rod 72 tends to be inserted into the locking hole 74 under the action of the locking spring 73, but because the telescopic shaft 3 rotates continuously, only one end part of the head of the locking rod 72 can be inserted into the locking hole 74, and then the top of the locking rod abuts against the telescopic shaft 3 under the action of the lifting spring, only when the telescopic shaft 3 rotates N full circles of stop rotation under the drive of the incomplete gear 12 (at this moment, the notch position on the incomplete gear 12 is corresponding to the rotating gear 15), the locking rod 72 is inserted into the locking hole 74 under the action of the locking spring 73 to realize the locking effect on the telescopic shaft 3, so as to avoid the rotation of the telescopic shaft 3 caused by the engagement of the sector gear 13 and the direction-adjusting gear 18 to drive the U-shaped frame 4 to rotate, we perform the chamfering setting on the top of the locking rod 72, so that when the telescopic shaft 3 rotates again, the locking rod 72 can be forced to withdraw from the locking hole 74 downwards.

Embodiment 4, on the basis of embodiment 3, referring to fig. 4, the telescopic shaft 3 includes a first shaft 30 rotatably mounted on the semi-cylinder 2, and a second shaft 31 is axially slidably mounted at the bottom of the first shaft 30, and a flexible spring 32 is connected between the first shaft 30 and the second shaft 31 (the flexible spring 32 can change hard contact into elastic contact between the wiping frame 5 and the part to be inspected of the patient, so that the patient can feel more comfortable during wiping of the disinfectant and smearing of the coupling agent), referring to fig. 5, the rotating gear 15 is fixedly sleeved on the upper end of the first shaft 30, and the U-shaped frame 4 is rotatably mounted at the bottom of the second shaft 31, referring to fig. 11, the direction-adjusting transmission device includes a first rod 33 rotatably mounted in the first shaft 30, and the direction-adjusting gear 18 is fixedly sleeved on the first rod 33, and a second rod 34 rotatably mounted in the second shaft 31 is axially slidably mounted at the bottom of, the bottom of the second rod 34 is connected with a bevel gear set 35 and drives the U-shaped frame 4 to rotate through the bevel gear set 35 (one bevel gear and the second rod 34 rotate coaxially, the other bevel gear and a rotating shaft of the U-shaped frame 4 rotate coaxially), and when the sector gear 13 is completely disengaged from the direction-adjusting gear 18 after being engaged with the direction-adjusting gear 18, the U-shaped frame 4 can be driven to rotate 180 degrees through the transmission of the bevel gear set 35 (by setting a proper transmission ratio), so that the positions of the wiping frame 5 for smearing disinfectant and the wiping frame 5 for smearing couplant are interchanged, and the smearing of the disinfectant and the smearing of the couplant are switched;

preferably, in order to prevent the U-shaped frame 4 from rotating with the second shaft 31 when the U-shaped frame 4 is driven by the telescopic shaft 3, that is, a certain positioning device is required to be arranged between the U-shaped frame 4 and the second shaft 31 for ensuring that the U-shaped frame 4 does not rotate with the second shaft 31 when driven by the telescopic shaft 3 to rotate in the semi-cylinder 2 and the protection cylinder 1, as shown in fig. 11, we slidably install a positioning rod 66 at the bottom of the second shaft 31 along the extending direction of the U-shaped frame and connect the positioning spring 67 with the bottom of the second shaft 31, we arrange a positioning hole 68 matching with the positioning rod 66 on the U-shaped frame 4 and chamfer one end of the positioning rod 66 inserted into the positioning hole 68, as shown in fig. 6, when the U-shaped frame 4 is not rotated, the positioning rod 66 is inserted into the positioning hole 68 under the action of the positioning spring 67 and realizes the positioning effect on the U-shaped frame 4, when the steering gear 18 drives the U-shaped frame 4 to rotate through the steering transmission device, the positioning rod 66 is forced to withdraw from the positioning hole 68 (one end of the positioning rod 66 inserted into the positioning hole 68 is chamfered, and when the positioning rod 66 receives a rotational acting force applied from the steering transmission device, the positioning rod 66 is forced to withdraw), so that when the U-shaped frame 4 rotates for a half turn, the positioning rod 66 is inserted into the positioning hole 68 again under the action of the positioning spring 67 to position the U-shaped frame 4.

Embodiment 5, on the basis of embodiment 1, referring to fig. 6, the wiping frame 5 includes a wiping body 36, the wiping body 36 is slidably mounted on the corresponding cantilever of the U-shaped frame 4 through a sliding rod 37 connected with the wiping body 36, the reciprocating transmission device includes a pulley set 38 rotatably mounted on the cantilever of the U-shaped frame 4 and a connecting frame 39 is fixedly mounted on the pulley set 38, the connecting frame 39 and the corresponding sliding rod 37 are rotatably mounted, when the telescopic shaft 3 drives the U-shaped frame 4 to rotate along the inside of the protection tube 1, the driving one-way gear 6 at the lower part is engaged with the corresponding inner gear ring 7, the driving one-way gear 6 is driven to rotate and transmit power to a first worm and gear transmission device 40 connected with the driving one-way gear 6, the first worm and gear transmission device 40 further realizes the rotation of the pulley set 38, and the rotation of the pulley set 38 and further synchronously drives the wiping frame 5 along one end of the cantilever of the U-shaped frame 4 through the connecting frame 39 connected with the driving one-way gear set 38, when the connecting frame 39 moves from one end of the pulley set 38 to one end of the pulley set 38, the pulley set 38 drives the connecting frame 39 and the corresponding slide rod 37 to rotate (the wiping frame 5 does not move in the process), so that after the connecting frame 39 passes over the end position of the pulley set 38, the pulley set 38 continues to drive the wiping frame 5 to move in the opposite direction through the connecting frame 39 (thereby realizing the effect of driving the wiping frame 5 to reciprocate);

when the driving one-way gear 6 is arranged, when the driving one-way gear 6 on the upper side is meshed with the inner gear ring 7 on the upper side, the driving one-way gear 6 can only idle under the action of the inner gear ring 7 corresponding to the driving one-way gear 6, and cannot transmit power to the corresponding belt wheel set 38, so that the effect of driving the wiping frame 5 on the upper side to move cannot be realized, and due to the arrangement of the first worm and gear transmission device 40, when the wiping frame 5 on the upper side does not move along the cantilever of the U-shaped frame 4, the shaking cannot be generated (the principle of worm and gear one-way transmission).

Embodiment 6, on the basis of embodiment 5, referring to fig. 7, the wiping gear 10 is rotatably mounted on one of the sliding rods 37, referring to fig. 8, the bottom of the sliding rod 37 is provided with a transmission gear 41 which coaxially rotates with the wiping gear 10, referring to fig. 9, the direction adjusting device comprises an input gear 42 which is meshed with the transmission gear 41, a first one-way gear 43 and a second one-way gear 44 are vertically arranged on the shaft of the input gear 42 at intervals, and when the transmission gear 41 drives the input gear 42 to rotate (whether the input gear rotates forward or reversely), the effect of transmitting power to an output gear 46 can be realized only through one of the one-way gears (at this time, the mounting mode of the first one-way gear 43 and the second one-way gear 44 on the shaft of the input gear 42 needs to be adjusted, that is, when the shaft of the input gear 42 rotates, only one of the one-way gears can be driven to rotate, while the other one-way gear is idle with the input gear 42 shaft);

assuming that the input gear 42 rotates forwards, the power is transmitted to the interval transmission device through the first one-way gear 43, the idle gear 45 and the output gear 46, and the meshing between the output gear 46 and the second one-way gear 44 does not prevent the idle rotation between the second one-way gear 44 and the input gear 42 in the process, assuming that the input gear 42 rotates backwards, the power is transmitted to the interval transmission device through the second one-way gear 44 and the output gear 46, and the meshing between the output gear 46 and the idle gear 45 as well as the meshing between the idle gear 45 and the first one-way gear 43 does not prevent the idle rotation between the first one-way gear 43 and the input gear 42 in the process;

that is, no matter the wiping gear 10 rotates forward or backward, the output gear 46 can be driven to rotate in the same direction through the cooperation of the gears, the interval transmission device is connected with the output gear 46, that is, the output gear 46 drives the interval transmission device to rotate in the same direction all the time and transmits power to the wiping transmission device at intervals, that is, when the interval transmission device does not drive the wiping transmission device 2, the wiping roller 8 does not rotate (in the process, the cotton cloth 9 wound around the bottom wall of the wiping frame 5 does not move and the wiping, cleaning and wiping of the disinfectant are realized), only when the interval transmission device drives the wiping transmission device to act, the wiping roller 8 is synchronously driven to rotate, the cotton cloth 9 covered on the bottom wall of the wiping frame 5 is replaced and collected and wound on the other wiping roller 8, can realize saving the beneficial effect of the 9 use amounts of cotton through setting up above-mentioned structure, use a period of time after through the cotton 9 that will cover at the 5 diapalls of wiping frame, change its use that can save cotton 9 again.

Embodiment 7, on the basis of embodiment 6, referring to fig. 10, the spacing transmission device includes a driving plate 47 rotating coaxially with the output gear 46, and a shift lever 48 is vertically slidably mounted on the driving plate 47, a driving spring 49 is connected between the shift lever 48 and the driving plate 47, a circular plate 50 (the circular plate 50 is disposed at a distance from the rotating shaft of the driving plate 47) coaxially with the driving plate 47 is rotatably mounted on the wiping body 36, referring to fig. 9, a torsion spring 51 is connected between the circular plate 50 and the wiping body 36 (one end of the torsion spring 51 is fixed on the circular plate 50, the other end is fixed on the wiping body 36, and the torsion spring 51 is disposed coaxially with the circular plate 50), a circular ring 52 is rotatably mounted coaxially on the outer circumferential surface of the circular plate 50, and ratchet teeth 53 are circumferentially disposed on the inner circumferential surface of the circular plate 52 at a distance, a pawl 54 matching with, a baffle plate 56 matched and matched with the deflector rod 48 is arranged on the lower end face of the circular plate 50 along the radial direction, an annular frame 57 which is positioned below the circular plate 50 and is coaxially arranged with the circular plate 50 is fixedly arranged on the wiping body 36, a sloping platform 58 which is coaxially arranged with the annular frame 57 is fixedly arranged on the lower end face of the annular frame 57, an arc-shaped bulge matched with the sloping platform 58 is fixedly arranged at the position, far away from the center of the circular plate 50, of the deflector rod 48 (as shown in the attached drawing 10), when the output gear 46 drives the driving plate 47 to rotate along the anticlockwise direction shown in the attached drawing 10 (whether the input gear 42 rotates forwards or backwards, the output gear 46 can be driven to rotate along the anticlockwise direction shown in the attached drawing 10 through the first one-way gear 43, the second one-way gear 44 and the idler gear 45 which;

referring to fig. 9, an incomplete tooth system 59 is arranged on the outer circumferential surface of the circular ring 52, the incomplete tooth system 59 is matched with a wiping transmission device arranged on the wiping body 36, referring to fig. 10, an arc-shaped protrusion fixedly arranged on the shift lever 48 at the beginning is set to be just contacted with the higher end of the ramp 58 (and the shift lever 48 is abutted against the side wall of the baffle 56 at the moment), when the output gear 46 drives the driving plate 47 to rotate along the counterclockwise direction shown in fig. 10, the circular plate 50 is driven to synchronously rotate counterclockwise through the shift lever 48 (in the process, the torsion spring 51 connected between the wiping body 36 and the circular plate 50 generates torsion along with the counterclockwise rotation of the driving plate 47, referring to fig. 9, the circular ring 52 is synchronously driven to rotate through the matched ratchet teeth 53 and pawls 54 along with the counterclockwise rotation of the circular plate 50), during the rotation of the driving plate, synchronously driving the arc-shaped protrusion fixed on the shift lever 48 to move along the ramp 58, in the process, the shift lever 48 gradually moves downwards under the action of the matched ramp 58 and arc-shaped protrusion and causes the driving spring 49 to be compressed, so that when the shift lever 48 is no longer in contact with the baffle 56, the driving plate 47 cannot continuously drive the circular plate 50 to rotate (and the circular plate 50 rotates in the opposite direction under the action of the torsion spring 51 to rotate to the initial position, as shown in fig. 9, when the circular plate 50 rotates in the clockwise direction, the pawl 54 rotatably mounted on the circular plate 50 cannot drive the ring 52 to rotate through the ratchet 53);

preferably, referring to fig. 9, we install a limit rod 69 on the wiping body 36 in a vertical sliding manner, and connect a limit spring 70 between the limit rod 69 and the wiping body 36, we have a plurality of limit holes 71 matching with the limit rod 69 on the lower end surface of the ring 52 in a surrounding manner (the angle interval between the limit holes 71 is the same as the angle of the circular plate 50 driven by the driving plate 47 each time), we set the initial time, the limit rod 69 is inserted into the limit hole 71 under the action of the limit spring 70, we perform chamfering on the top of the limit rod 69, when the driving plate 47 drives the circular plate 50 to rotate through the matching deflector rod 48 and the baffle plate 56, we force the limit rod 69 to withdraw from the limit hole 71, so that the deflector rod 48 and the baffle plate 56 are completely separated (at this time, the ring 52 stops rotating, and just make another limit hole 71 installed on the lower end surface of the ring 52 rotate to a position corresponding to the limit rod 69, then the limit rod 69 is inserted into the limit hole 71 under the action of the limit spring 70 and achieves a certain limit effect on the circular ring 52), then the circular plate 50 rotates in the opposite direction under the action of the torsion spring 51 and rotates to the initial position, and the reset is completed (at this time, the incomplete tooth system 59 arranged on the outer circular surface of the circular ring 52 is not meshed with the wiping transmission device, so the wiping roller 8 does not rotate, and the cotton cloth 9 covering the bottom wall of the wiping body 36 is used for wiping and smearing the disinfectant all the time in the process);

because the driving plate 47 always rotates along the counterclockwise direction, when the driving plate 47 drives the shift lever 48 to rotate again along the counterclockwise direction to the position shown in fig. 10 (that is, the shift lever 48 rotates again to the position contacting with the baffle 56 fixedly installed on the lower end surface of the circular plate 50), at this time, the driving plate 47 drives the circular plate 50 to rotate again through the shift lever 48 and the baffle 56, and then the following process is the same, so that the incomplete tooth system 59 arranged on the outer circumferential surface of the circular ring 52 is meshed with the wiping transmission device and drives the wiping transmission device to rotate, and the wiping transmission device rotates to drive the wiping roller 8 to rotate, thereby replacing the cotton cloth 9 covered on the bottom wall of the wiping body 36 (avoiding that the effect of wiping the disinfectant clean after the cotton cloth 9 is used for a long time is not achieved), we can correspondingly set the arc length corresponding to the incomplete tooth system 59 according to the actual situation when the incomplete tooth system 59 is, so that when the incomplete toothing 59 is disengaged from the wiping drive, the wiping roller 8 is driven into rotation and the effect of completely replacing the cotton cloth 9 covering the bottom wall of the wiping body 36 is achieved.

Embodiment 8, on the basis of embodiment 7, referring to fig. 9, the wiping transmission device includes a spacing gear 60 rotatably mounted on the wiping body 36 and engaged with the incomplete gear train 59, the spacing gear 60 drives a second worm gear 61 provided on the wiping body 36 (the second worm gear 61 is disposed such that the wiping roller 8 does not rotate when the incomplete gear train 59 is not engaged with the spacing gear 60, and the one-way transmission principle of the worm gear is utilized), and the second worm gear 61 drives the wiping roller 8 to rotate through a belt transmission 62, thereby achieving the effect of replacing the cotton cloth 9 covered on the bottom wall of the wiping body 36.

Embodiment 9, based on embodiment 8, referring to fig. 6, we provide a collision round bar 63 at one end of the U-shaped frame 4 away from the telescopic shaft 3 along the radial direction of the semi-cylinder 2, referring to fig. 5, when the U-shaped frame 4 rotates circumferentially along the inside of the protective cylinder 1, the collision round bar 63 is synchronously driven to rotate along the inner walls of the protective cylinder 1 and the semi-cylinder 2, and when the motor drives the U-shaped frame 4 to rotate N full circles, the U-shaped frame 4 rotates to the initial position again (i.e., as shown in fig. 1, when the initial position is reached, one end of the U-shaped frame 4 away from the telescopic shaft 3 is located at the rotation installation position of the semi-cylinder 2 and the protective cylinder 1);

referring to fig. 5, a jacking ramp 64 capable of moving along the radial direction of the protection cylinder 1 is arranged at the rotary mounting position of the semi-cylinder 2 and the protection cylinder 1 (referring to fig. 2, the jacking ramp 64 is driven by an electric push rod 65 fixed on the protection cylinder 1 to further achieve the effect of driving the jacking ramp 64 to move along the radial direction of the protection cylinder 1), when a motor drives the U-shaped frame 4 to rotate in the protection cylinder 1, the electric push rod 65 is controlled to enable the jacking ramp 64 not to hinder the rotation of the U-shaped frame 4 in the circular cylinder formed by the protection cylinder 1 and the semi-cylinder 2 (i.e. the electric push rod 65 is contracted to drive the jacking ramp 64 to move outwards along the radial direction), when the motor drives the U-shaped frame 4 to rotate 2N +1 for a full circle, the electric push rod 65 extends and drives the jacking ramp 64 to move towards the position close to the center of the protection cylinder 1 along the radial direction, so that when the abutting round rod 63 fixed on the U-shaped frame 4 rotates 2N +1 full circle along with the telescopic shaft 3 (i.e. at the initial position), the abutting round rod 63 moves upward under the action of the jacking ramp 64 to drive the U-shaped frame 4 to move upward and shorten the telescopic shaft 3 (i.e. to make the second shaft 31 and the first shaft 30 move vertically, and we set that when the abutting round rod 63 contacts with the arc-shaped surface of the jacking ramp 64, the driving one-way gear 6 rotatably mounted on the U-shaped frame 4 is already separated from the inner gear ring 7 corresponding thereto), referring to fig. 4, when the abutting round rod 63 contacts with the horizontal part of the jacking platform, we can open the semi-cylindrical barrel 2 and rotate to open it, and at this time, a doctor can put the ultrasonic probe into the protective barrel 1 to perform subsequent ultrasonic examination;

a buckle (not shown in the figure) is arranged at one free rotating end of the semi-cylinder 2, the semi-cylinder 2 and the protective cylinder 1 are positioned through the buckle, when the semi-cylinder 2 needs to be opened, the buckle is unlocked, the positioning between the semi-cylinder 2 and the protective cylinder 1 is further released, in the process of rotating the semi-cylinder 2, the abutting round rod 63 always abuts against the horizontal position of the upper end face of the jacking platform, so that the jacking platform is arranged, when the semi-cylinder 2 is opened, the situation that the lower end face of the wiping frame 5 below the U-shaped frame 4 is lower than the bottom of the protective cylinder 1 and is provided with a plurality of suckers 75 is avoided, the semi-cylinder 2 cannot be opened due to the fact that the wiping frame 5 below the U-shaped frame 4 touches the sucker 75 at the bottom of the protective cylinder 1 when the semi-cylinder 2 is opened, and the jacking platform can be used for opening the semi-cylinder 2, lifting the wiping frame 5 below the U-shaped frame 4 upwards for a certain distance and enabling the wiping frame to outwards cross the protective cylinder 1 along with the rotation of the semi-cylinder 2 and be provided with a plurality of suckers 75, after the user finishes the over-life examination, the semi-cylinder 2 needs to be closed, after the semi-cylinder 2 and the protective cylinder 1 are positioned through a buckle, the electric push rod 65 is controlled to contract, the jacking platform moves towards the direction far away from the telescopic shaft 3, and the jacking platform resets;

it is to be noted here that: when the motor drives the telescopic shaft 3 to rotate for N whole circles, the U-shaped frame 4 is driven to rotate through the direction-adjusting gear 18, so that the positions of the two wiping frames 5 are exchanged, at this time, the electric push rod 65 is also controlled to move the jacking sloping platform 64 towards the direction close to the telescopic shaft 3, so that when the motor drives the telescopic shaft 3 to rotate for N whole circles, the U-shaped frame 4 is lifted upwards by a certain distance under the action of the abutting round rod 63 and the jacking sloping platform 64, so as to reserve space allowance for the rotation of the U-shaped frame 4 (when the U-shaped frame 4 is wiped by a normal disinfectant, the wiping frame 5 positioned below is in contact with the part to be inspected of the patient, if the U-shaped frame 4 is not lifted upwards, the U-shaped frame 4 cannot be rotated or the U-shaped frame 4 is rotated, so that the part to be inspected of the patient is punctured), and after the U-shaped frame 4 rotates for half a circle (namely, after the positions of the two U, we control the electric push rod 65 to move the lifting ramp 64 away from the telescopic shaft 3 so that it does not interfere with the rotation of the subsequent U-shaped frame 4 (i.e. the coating process of the coupling agent).

The uniform coating device can firstly realize the wiping and disinfection of the part to be inspected of a patient, and then coats the coupling agent on the part to be inspected after the disinfection and cleaning are finished, the whole process is within the range of the protective cylinder 1 and the semi-cylinder 2 which are matched, so that the phenomenon that part of the disinfection solution or the coupling agent is diffused to the part which does not need to be inspected in the wiping process of the disinfection solution and the coating process of the coupling agent, the waste of the disinfection solution and the coupling agent is caused, the area of a cleaning area required by the later-stage completion of the inspection and the cleaning is equivalent to that of the part area to be inspected, and the cleaning work in the later stage is easier;
