Description
Technical Field
The invention relates to the technical field of medical instrument manufacturing, in particular to a transfusion device convenient to use.
Background
At present, infusion is a common medical means, and the basic principle is to fill liquid medicine into infusion containers such as an infusion bottle, an infusion bag and the like, wherein one end of a plastic infusion tube is inserted into a sealing position of the infusion bottle or the infusion bag through a connecting end (usually a connecting needle) so as to enable the infusion tube to be communicated with the liquid medicine in the infusion bottle or the infusion bag, the other end of the infusion tube is connected with an infusion needle used for being connected with an arm of a patient, and a dripping speed control valve is further arranged in the middle of the infusion tube so as to regulate and control the infusion speed. During infusion, the infusion needle is required to be connected with the vein of the hand of a patient lying on a sickbed or a chair, and an infusion bottle or an infusion bag is required to be hung on an infusion support at a high position so as to be dripped into the vein of the patient by means of the potential energy of liquid medicine.
However, the prior infusion device has the following inconvenience in the use process: firstly, in order to ensure the normal operation of infusion, the infusion container needs to be hung on a higher infusion support, and in the infusion process, when a patient needs to go to a toilet by walking, a caregiver needs to be helped to lift the infusion container (to play a role similar to the infusion support), although the patient can also lift the infusion container by one hand, when the patient reaches the toilet to relieve the bowels, the patient cannot lift the infusion container by hand. In order to bring convenience to a patient to go to a toilet, a hook is specially arranged on a wall of the toilet, and when the patient enters the toilet, the infusion container can be firstly hung on the hook to free hands to solve the problem of going to the toilet. However, the solution still cannot meet the requirement that the patient needs to leave the transfusion position such as a ward for some reason. That is, the prior art infusion devices typically require an attendant to attend to the patient. Once the accompanying person temporarily leaves due to the accident, the patient will have inconvenience in movement. Secondly, because the link of transfer line is pegged graft in the sealed department of infusion bottle or infusion bag, and the infusion syringe needle of transfer line also "pegs graft" in the hand of disease, and through the sticky tape location, it is medical personnel's operation when convenient infusion, but its connection is not reliable enough, when the disease, or other medical care and even accompanying personnel touch the transfer line by mistake carelessly, then when pulling the transfer line formation, take place easily to connect the syringe needle and drop from the sealed department of infusion bottle or infusion bag, or the problem that the infusion syringe needle "pulled out" from the disease hand, waste expensive medicine then, if above-mentioned problem is not in time discovered, the problem that the disease caused the air cock because of vein "admits air" still can take place for another time.
Disclosure of Invention
The invention aims to provide a transfusion device convenient to use, which is convenient for a patient to freely move on the premise of no accompanying person on one hand, and can effectively avoid the separation of a transfusion tube from a transfusion container or the hand of the patient during transfusion on the other hand, thereby ensuring the safety of transfusion.
In order to achieve the purpose, the invention adopts the following technical scheme:
a transfusion device convenient to use comprises a transfusion support and a transfusion tube, wherein the transfusion support is used for hanging a transfusion container, one end of the transfusion tube is provided with a connecting end which is spliced with a sealing part of the transfusion container, the other end of the transfusion tube is provided with a transfusion needle head, the transfusion tube is also provided with a dripping speed control valve for controlling the transfusion speed, the transfusion device further comprises a movable base with a movable wheel, and a lifting rod vertically arranged on the movable base, the upper end of the lifting rod is provided with a butt joint strip, the free end of the butt joint strip inclines upwards, the movable base is provided with a driving mechanism for controlling the lifting rod to ascend and descend, a power mechanism for driving the movable base to walk through the movable wheel, and a control part for controlling the moving direction of the movable base, the transfusion support comprises a sliding rail which inclines downwards, the transfusion container comprises a sliding part which can movably arranged on the sliding rail, and the lower end of the sliding rail is provided with a limiting mechanism for preventing the sliding part from moving outwards, be equipped with anti brace on the transfer line, tensile strip one end is the first connecting portion of connection on infusion container, and the other end is the second connecting portion of connection at the disease hand, and when the disease needs to walk about, actuating mechanism makes the lifter extension, and the free end of butt joint strip butt slide rail, stop gear action release infusion container's sliding part this moment, infusion container slides down and gets into the butt joint strip, and control unit control removes the base and removes the position that needs the reacing to the disease.
Similar to the prior art, the infusion device comprises an infusion tube, wherein one end of the infusion tube is provided with a connecting end inserted with the sealing part of an infusion container, the other end of the infusion tube is provided with an infusion needle, and the infusion tube is also provided with a dropping speed control valve for controlling the infusion speed. When infusion is needed, the connecting end can be inserted into the sealing position of the infusion container, then the infusion needle is connected with the hand vein of a patient, and the dropping speed control valve is adjusted, so that the liquid medicine in the infusion bottle or the infusion bag can be dropped into the vein of the patient.
Unlike the prior art, the infusion support of the present invention includes a slide rail and the infusion container includes a slide movably located on the slide rail. That is, the infusion container can move transversely on the slide rail, and because the slide rail inclines downwards, the infusion container can automatically slide to the lower end of the outer side of the slide rail under the action of self gravity and is positioned by the limiting mechanism.
In addition, the invention also comprises a movable base with movable wheels, and a lifting rod is arranged on the movable base. Therefore, when the disease need leave original infusion position, accessible actuating mechanism makes the lifter extend to as high as the infusion container, the free end of butt joint strip of up-slope of lifter upper end butt joint slide rail up to, stop gear action this moment, release infusion container's sliding part, infusion container is automatic to slide down and gets into the butt joint strip, the disease can remove the base through control unit control and remove the position that needs the arrival to the disease, and then drive infusion container through the lifter and follow the disease and arrive any place, make things convenient for going by oneself of infusion disease.
It should be noted that the control unit can be used to control the movement of the mobile base by using the existing wireless control technology, such as remote control car, so as to facilitate the control of the patient.
In addition, the invention also comprises an anti-pulling strip arranged on the infusion tube, wherein one end of the anti-pulling strip is a first connecting part connected to the infusion container, and the other end of the anti-pulling strip is a second connecting part connected to the hand of the patient. Therefore, when a patient, other medical care personnel or even accompanying personnel accidentally touch the infusion tube and pull the infusion tube, the anti-pulling strip is stressed firstly, so that the separation of the infusion tube and an infusion container or the extraction of the infusion needle from the hand of the patient can be effectively avoided. It will be appreciated that the effective length of the anti-pull strip between the first and second connections is shorter than the effective length of the tubing to ensure that the anti-pull strip is stressed prior to the tubing. Certainly, we should make the second connecting portion form the detachable connection with the hand of patient, make first connecting portion and infusion container form the detachable connection, both conveniently connect, conveniently demolish again, promote medical personnel's work efficiency then.
Preferably, the lifting rod is a multi-stage oil cylinder and comprises an outer cylinder sleeve connected with the moving base, a plurality of lifting sleeves arranged in the outer cylinder sleeve in a liftable and liftable mode, and a piston rod arranged in the innermost lifting sleeve, the butt joint strip is arranged at the upper end of the piston rod, a hydraulic oil tank is arranged in the moving base, an oil motor is arranged on the moving base, an oil inlet of the oil motor is communicated with the hydraulic oil tank through a pipeline, an oil outlet of the oil motor is communicated with the multi-stage oil cylinder through a pipeline, and an electromagnetic control valve is arranged on the pipeline connecting the oil outlet and the multi-stage oil cylinder.
It is known that a cylinder enables a simple telescopic mechanism in the prior art, and the prior cylinder usually comprises a cylinder body and a piston rod, and the telescopic length of the piston rod does not exceed the length of the cylinder body. Since the maximum length of the lift lever should be about 1.8m, when the lift lever adopts a cylinder structure, the initial length of the lift lever may be about 1m, which is inconvenient for storage and use. The lifting rod is a multi-stage oil cylinder and specifically comprises an outer cylinder sleeve connected with the movable base, a plurality of lifting sleeves which are overlapped in the outer cylinder sleeve in a lifting way, and a piston rod arranged in the innermost lifting sleeve. That is, the cylinder block therein includes an outer cylinder liner and a plurality of lift sleeves, so that the initial length of the entire lift lever can be significantly shortened. When the lifting rod needs to be lifted, hydraulic oil with pressure can be input into the multi-stage oil cylinder through the oil motor, so that the piston rod can extend out of the lifting sleeve on the innermost layer, the lifting sleeve on the inner layer extends out of the lifting sleeve on the outer layer, and the lifting sleeve is lifted out of the outer cylinder sleeve. Certainly, a radially outward-expanded flange ring can be arranged at the lower end of the inner-layer lifting sleeve, and a limiting necking is arranged at the upper end of the outer-layer lifting sleeve. When the lifting rod is provided with input hydraulic oil, the inner-layer lifting sleeve can upwards lift out of the outer-layer lifting sleeve until the flange ring of the inner-layer lifting sleeve abuts against the necking of the outer-layer lifting sleeve to be positioned.
It will be appreciated that the height of the docking bar and the height of the suspension of the infusion container are not very well defined data, and therefore, we can make the lifting rod as long as possible until the docking bar abuts the slide rail from the underside. Of course, a normally open position switch may be provided at the end of the docking head. When the docking bar abuts against the slide rail from the lower side, the position switch is activated, thereby stopping the oil motor.
Preferably, a plurality of lantern rings sleeved on the infusion tube are arranged on the anti-pulling strip at intervals along the axial direction, a hook is arranged on the infusion container, the first connecting part is hooked on the hook part, and the second connecting part surrounds the wrist of the patient and is connected into a ring shape through a magic tape.
The lantern ring makes anti brace and transfer line form structure side by side, and on the one hand, the transfer line can be dragged by the mistake with the tensile strip simultaneously to ensure that anti brace can the effectual atress of sharing the transfer line, on the other hand, ensure that the transfer line can be tensile strip freely movable relatively. It should be noted that the second connecting portion of the anti-pulling strip can be provided with a corresponding magic tape, and when the second connecting portion surrounds the wrist of the patient, the second connecting portion can be reliably connected into a ring sleeve shape through the magic tape, so that the connection and the removal are convenient, and the connection reliability is ensured.
Preferably, the movable base is in a disc shape, a liftable positioning rod is arranged at the center of the lower side of the movable base, a rotatable positioning disc is arranged at the lower end of the positioning rod, the positioning rod is associated with the control part, 3-4 wheels which are uniformly distributed in the circumferential direction are arranged at the lower side of the movable base, one of the wheels is a driving wheel with a wheel hub motor, the other wheels are universal wheels, the driving wheel comprises a wheel fork which is rotatably connected with the movable base, and a steering mechanism for driving the wheel fork to rotate, when the movable base needs to be moved, the wheel hub motor drives the driving wheel to rotate so as to enable the movable base to move forwards or backwards, and the rotating mechanism controls the rotation of the wheel fork so as to control the moving directions of the driving wheel and the movable base; when the movable base needs to be positioned, the positioning rod extends downwards, so that the positioning disc is contacted with the ground for positioning.
Because the center of the lower side of the movable base is provided with the liftable positioning rod and the lower end of the positioning rod is provided with the rotatable positioning disc, when the movable base moves to a certain position and needs to be positioned, the positioning rod can extend downwards through the control part until the positioning disc contacts the bottom surface to be positioned. Particularly, the positioning disc is rotatably connected with the positioning rod, so that when the mobile base needs to turn at a large angle or even turn around, the mobile base can be stopped from moving, then the center of the mobile base is positioned through the positioning rod, then the mobile base rotates at the original place by the required angle, then the positioning rod is contracted, the driving wheel is restarted, and the mobile base moves forwards. Certainly, a motor can be arranged on the movable base, an output shaft of the motor is connected with the positioning rod, when the positioning rod enables the movable base to be positioned, the motor can be started, and the movable base can rotate relative to the positioning rod at the moment.
In addition, the lower side of the movable base is provided with a driving wheel and 2-3 universal wheels, so that when the driving wheel operates to drive the movable base to move, the other universal wheels can automatically adjust the direction. That is, the moving direction of the movable base can be conveniently controlled by controlling the direction of one driving wheel through the steering mechanism.
Preferably, the steering mechanism comprises a steering motor and a poke rod, the poke rod comprises an inner rod and an outer rod, the inner rod is in cross connection with the wheel fork, the outer rod is sleeved on the inner rod, a motor shaft of the steering motor is connected with a screw rod, a driving sleeve is in threaded connection with the screw rod, the outer rod is hinged to the middle of the driving sleeve, when the steering motor drives the screw rod to rotate, the driving sleeve moves axially and then drives the outer rod to rotate, so that the wheel fork rotates, and the length of the poking rod is automatically adjusted by the aid of the axial movement of the outer rod relative to the inner rod at the moment.
When the movable base needs to be turned, the turning motor can be started, so that the screw rod is driven to rotate, the driving sleeve is driven to axially move, and the wheel fork and the driving wheel are driven to rotate through the poke rod to change directions. It can be understood that when the poke rod rotates, the movement of the hinged point of the poke rod and the driving sleeve is arc-shaped. Therefore, the poke rod comprises the inner rod and the outer rod which can move relatively, so that the poke rod is prevented from interfering with the driving sleeve. In addition, because the driving sleeve is hinged with the poke rod, the driving sleeve cannot rotate along with the screw rod, and therefore the forward and backward movement of the screw rod can be guaranteed. Of course, bearing seats can be arranged on the movable base to support the two ends of the screw rod.
Therefore, the invention has the following beneficial effects: on one hand, the transfusion tube can be conveniently and freely moved by a patient on the premise of no accompanying person, and on the other hand, the transfusion tube can be effectively prevented from being separated from the transfusion container or the hand of the patient during transfusion, so that the transfusion safety is ensured.

Detailed Description
The invention is further described with reference to the following detailed description and accompanying drawings.
As shown in fig. 1, a convenient infusion device comprises an infusion support 1 for hanging an infusion container, an infusion tube 3, one end of the infusion tube is provided with a connection end (usually a connection needle) inserted into a sealing position of the infusion container, the other end of the infusion tube is provided with an infusion needle, and the infusion tube is further provided with a dropping speed control valve 31 for controlling the infusion speed. When infusion is needed, the connecting end can be inserted into the sealing position of an infusion container 2 such as an infusion bottle or an infusion bag, then the infusion needle is connected with the hand vein of a patient, and the dropping speed control valve is adjusted, so that the liquid medicine in the infusion bottle or the infusion bag can be dropped into the vein of the patient.
In order to facilitate the patient to walk by himself during transfusion, as shown in fig. 2, the present invention further comprises a moving base 4 having moving wheels, and a lifting rod 5 vertically disposed on the moving base, wherein the upper end of the lifting rod is provided with a butt-joint strip 51, and the free end of the butt-joint strip is inclined upwards, so that the butt-joint strip and the lifting rod are connected into a 7-shape. The moving base is provided with a driving mechanism for controlling the lifting rod to lift up and down, a power mechanism for driving the moving base to move through the moving wheel, and a control component for controlling the moving direction of the moving base. Furthermore, the infusion support comprises a downwardly inclined slide rail 11, and the infusion container comprises a sliding part 21 movably arranged on the slide rail, and when the medical staff connects the sliding part of the infusion container on the slide rail in a sliding way, the infusion container can automatically slide to the lower end of the slide rail under the action of self gravity. Of course, it is necessary to provide a stop mechanism at the lower end of the slide rail to prevent the slide from moving outward so that the infusion container can be reliably positioned at the lower end of the slide rail.
When a patient needs to leave an original infusion position and walk, the lifting rod can be extended to be as high as an infusion container through the driving mechanism until the hanging end of the butt joint strip with the upper end of the lifting rod inclined upwards abuts against the hanging end of the sliding rail, the limiting mechanism acts at the moment to release the sliding part of the infusion container, the infusion container automatically slides downwards to enter the butt joint strip, the patient can move to the position where the patient needs to arrive through the control part control moving base, the lifting rod at the moment becomes a movable infusion support, and the infusion support can follow the patient to arrive at any place.
It should be noted that the control component can be used to control the movement of the movable base in the existing wired or wireless control manner similar to a remote control car, so as to facilitate the independent control of the patient. In addition, the invention can be provided with a general controller to control the extension and contraction of the lifting rod and the movement of the movable base.
In addition, in order to simplify the structure, as shown in fig. 3 and 4, the limiting mechanism comprises a limiting hole 111 which is arranged near the suspension end of the slide rail and is approximately vertical, an avoiding groove 112 communicated with the limiting hole is arranged at the end part of the slide rail, a stop pin 7 is arranged in the limiting hole, the upper end of the stop pin is hinged with a limiting section 71, the stop pin comprises a control section 72 which extends out of the limiting hole downwards, a limiting ring 73 is arranged between the control section and the stop pin, a moving section 113 with enlarged aperture is arranged in the limiting hole, and the limiting ring is positioned in the moving section, so that the stop pin can move up and down. In addition, a pressure spring 74 which is pressed downwards against the limiting ring is arranged in the moving section.
Under initial condition, the pressure spring drives the stop pin to move downwards through the limiting ring and retracts into the limiting hole, the lower part of the limiting section at the moment is positioned in the limiting hole, the upper part of the limiting section extends out of the limiting hole, and the sliding part of the infusion container outwards moves along the sliding rail to abut against the limiting section for positioning. When the patient needs to leave the original transfusion position and walk, the lifting rod rises, the suspended end of the butt joint strip with the upper end inclined upwards abuts against the control section on the lower side of the suspended end of the slide rail, the stop pin moves upwards, and the limiting section hinged with the stop pin rotates outwards under the action of the transfusion container and sinks in the avoiding groove. At the moment, the sliding part of the transfusion container can continuously slide outwards along the sliding rail and enter the butt joint strip. Of course, a slope may be provided at the end of the slide rail to facilitate a smooth transition of the infusion container to the docking head.
It will be appreciated that patients often require the continuous infusion of several bottles or bags of medication, i.e. there will be more than one infusion container. Therefore, the infusion support can be made into a T shape (which is suitable for the infusion support fixed on the ground) or an inverted T shape (which is suitable for the infusion support hung on the ceiling of a ward), and the infusion support comprises a well-known straight rod and a cross rod connected to the end part of the straight rod, wherein one end of the cross rod is a sliding rail inclining downwards, and the other end of the cross rod is used for hanging an infusion container to be infused. After the transfusion of the transfusion container on one side of the slide rail is finished, the medical staff can hang the transfusion container on the other side on the slide rail for continuous transfusion.
Preferably, a pulley with a hook can be arranged on the sliding rail, a mesh bag is arranged on the outer side of the hard infusion bottle, and a hanging ring is arranged on the mesh bag; or a hanging hole is arranged on the flexible infusion bag. During infusion, the infusion container can smoothly slide to the lower end of the sliding rail only by hanging the hanging ring or the hanging hole of the infusion container on the hook of the pulley.
It should be noted that the pulley with the hook and the corresponding slide rail can refer to the existing curtain rail structure, and are not described in detail in this embodiment.
In addition, as shown in fig. 5, the infusion tube may be provided with an anti-pulling strip 32, one end of which is a first connection part connected to the infusion container, and the other end of which is a second connection part connected to the hand of the patient (not shown).
Therefore, when a patient, other medical care personnel or even accompanying personnel accidentally touch the infusion tube and pull the infusion tube, the anti-pulling strip is stressed firstly, so that the separation of the infusion tube and an infusion container or the extraction of the infusion needle from the hand of the patient can be effectively avoided. It will be appreciated that the effective length of the anti-pull strip between the first and second connections is shorter than the effective length of the tubing to ensure that the anti-pull strip is stressed prior to the tubing. Certainly, we should make the second connecting portion form the detachable connection with the hand of patient, make first connecting portion and infusion container form the detachable connection, both conveniently connect, conveniently demolish again, promote medical personnel's work efficiency then.
Preferably, first connecting portion include flexible winding area, and when needing the infusion, the winding is taken the accessible double faced adhesive tape and is bonded in the infusion container outside, perhaps, the winding is taken the accessible magic and is pasted the winding adhesion in the infusion container outside, and even, first connecting portion can set up the connection couple, sets up on the infusion container and connects the hanging hole, and when the connection couple hook of first connecting portion hung on the connection hanging hole of infusion container, can realize first connecting portion and infusion container's reliable connection. In addition, the second connecting part can be wound on the wrist of the patient through a quick connecting structure such as a magic tape or a Chinese character 'ri' buckle and is reliably connected. The present invention is not focused on such connection, and therefore, the present embodiment will not be described in detail.
Further, a plurality of lantern rings 321 sleeved on the infusion tube are axially arranged on the anti-pulling strip at intervals, the lantern rings are fixedly connected with the anti-pulling strip, the diameter of the lantern rings can be reduced as much as possible, and the infusion tube can freely slide in the lantern rings. The infusion container is provided with a hook, the first connecting part is hooked on the hook part, and the second connecting part surrounds the wrist of a patient and is connected into a loop shape through a magic tape.
The lantern ring makes anti brace and transfer line form structure side by side, and on the one hand, the transfer line can be dragged by the mistake with the tensile strip simultaneously to ensure that anti brace can the effectual atress of sharing the transfer line, on the other hand, ensure that the transfer line can be tensile strip freely movable relatively. That is to say, when the tensile bar and the infusion tube are pulled simultaneously, the infusion tube is in an unstressed state which can freely slide relative to the tensile bar, thereby effectively avoiding the disconnection of the infusion tube and an infusion container or a wrist of a patient. It should be noted that the second connecting portion of the anti-pulling strip can be provided with a corresponding magic tape, and when the second connecting portion surrounds the wrist of the patient, the second connecting portion can be reliably connected into a ring sleeve shape through the magic tape, so that the connection and the removal are convenient, and the connection reliability is ensured.
As a preferable scheme, as shown in fig. 6, the lifting rod is a multi-stage cylinder, and specifically includes an outer cylinder sleeve 52 connected to the moving base, a plurality of lifting sleeves 53 stacked in the outer cylinder sleeve in a lifting manner, and a piston rod 54 disposed in the innermost lifting sleeve, the butt joint strip is disposed at the upper end of the piston rod, a hydraulic oil tank is disposed in the moving base, an oil motor is disposed on the moving base, an oil inlet of the oil motor is communicated with the hydraulic oil tank through a pipeline, an oil outlet of the oil motor is communicated with the bottom of the multi-stage cylinder through a pipeline, and an electromagnetic control valve is disposed on the pipeline connecting the oil outlet and the multi-stage cylinder.
When the lifting rod needs to be lifted, the oil motor can be started, so that hydraulic oil with pressure is input into the multi-stage oil cylinder, at the moment, the piston rod can upwards extend out of the lifting sleeve on the innermost layer, the lifting sleeve on the inner layer extends out of the lifting sleeve on the outer layer, and the lifting sleeve is lifted out of the outer cylinder sleeve. Of course, a radially outward-expanded flange ring 531 may be disposed at the lower end of the inner lifting sleeve, and a sealing ring may be disposed on the flange ring to seal the flange ring and the outer lifting sleeve. That is, the flange ring now functions like a piston. In addition, a limiting necking 532 is arranged at the upper end of the outer-layer lifting sleeve. When the lifting rod has input hydraulic oil, the lifting sleeve on the inner layer can upwards lift out of the lifting sleeve on the outer layer until the flange ring of the lifting sleeve on the inner layer abuts against the necking of the lifting sleeve on the outer layer to be positioned.
It should be noted that we can reasonably set the diameter of each layer of lifting sleeve and the area parameter of the corresponding flange ring to ensure the following sequence of the extension of the lifting rod when inputting hydraulic oil with pressure into the multi-stage oil cylinder: the wire extends out of the piston rod, then extends out of the innermost lifting sleeve outside the piston rod, and then sequentially extends out of the lifting sleeves of all layers from inside to outside.
To control the extension height of the lifting rod, a normally open position switch can be arranged at the end of the butt joint strip, and the position switch is connected with an oil motor. When the lifting rod extends and the butt joint strip abuts against the sliding rail from the lower side, the position switch is started, so that the oil motor stops running through the controller.
Further, the movable base is disc-shaped, a positioning rod 41 capable of lifting is vertically arranged at the center of the lower side of the movable base, a positioning disc 411 is arranged at the lower end of the positioning rod, and the positioning rod is associated with a controller of the control component. In addition, 3-4 wheels 43 which are uniformly distributed in the circumferential direction are arranged at the lower side edge of the movable base, one of the wheels is a driving wheel with a hub motor, the rest wheels are driven universal wheels, and the driving wheel comprises a wheel fork which is rotationally connected with the movable base and a steering mechanism which drives the wheel fork to rotate.
When the patient needs to walk and the movable base needs to move, the controller enables the hub motor to operate, so that the driving wheel is driven to rotate, and the movable base moves forwards or backwards. Of course, the positioning rod is in a contracted state, and the positioning disc at the lower end is separated from the bottom surface. Meanwhile, the rotation of the wheel fork can be controlled through the rotating mechanism, and then the moving directions of the driving wheel and the moving base are controlled; when the movable base needs to be stopped for positioning, the controller enables the hub motor to stop and the driving wheel to stop rotating on one hand, and enables the positioning rod to extend downwards on the other hand, and then the positioning disc is enabled to be in contact with the ground for positioning.
It can be understood that when the driving wheel is operated to drive the movable base to move, the other universal wheels can automatically adjust the direction. That is, the moving direction of the movable base can be conveniently controlled by controlling the direction of one driving wheel through the steering mechanism.
Preferably, the positioning disc is rotatably connected with the positioning rod, so that when the mobile base needs to turn around at a large angle, the mobile base can be stopped from moving, then the center of the mobile base is positioned through the positioning rod, then the mobile base can rotate in place at a required angle through the driving wheel, and then the positioning rod is retracted and the driving wheel is restarted, so that the mobile base can move forwards.
Alternatively, as shown in fig. 7, a motor 44 may be fixed to the movable base, an output shaft of the motor is connected to the positioning rod, and a threaded sleeve 45 connected to the positioning rod is disposed on the movable base. When the motor runs, the positioning rod can extend downwards or retract upwards. When the positioning rod extends downwards to the position disc to be abutted against the ground for positioning, the motor continues to rotate, the position disc cannot continue to rotate at the moment, and the movable base and the motor generate rotation relative to the positioning rod and the position disc, so that the movable base is rotated in situ. Certainly, the locating disc and the locating lever at this moment should be fixed connection to accessible spline or regular hexagon jack and bolt are pegged graft between the output shaft of motor and the locating lever, so that the relative output shaft of locating lever removes.
In order to facilitate the steering of the movable base, as shown in fig. 8, the steering mechanism includes a steering motor 6 and a shifting rod 61, the shifting rod includes an inner rod 611 cross-connected with the wheel fork 431 and an outer rod 612 sleeved on the inner rod, a motor shaft of the steering motor is connected with a screw 62, a driving sleeve 63 is connected to the screw in a threaded manner, and the outer rod is hinged to the middle of the driving sleeve. When the steering motor drives the screw rod to rotate, the driving sleeve moves along the axial direction to drive the outer rod to rotate, so that the wheel fork rotates, and the outer rod moves axially relative to the inner rod at the moment to automatically adjust the length of the toggle rod.
When the movable base needs to be turned, the turning motor can be started, so that the screw rod is driven to rotate, the driving sleeve is driven to axially move, and the wheel fork and the driving wheel are driven to rotate through the poke rod to change directions. It can be understood that when the poke rod rotates, the movement of the hinged point of the poke rod and the driving sleeve is arc-shaped. Therefore, the poke rod comprises the inner rod and the outer rod which can move relatively, so that the poke rod is prevented from interfering with the driving sleeve. In addition, as the driving sleeve is hinged with the poke rod, the driving sleeve cannot rotate along with the screw rod, so that the forward and backward movement of the driving sleeve can be ensured. Of course, bearing seats can be provided on the mobile base to support the two ends of the screw. Of course, the steering motor may employ a stepping motor to precisely control the rotation direction thereof.
It is understood that, in the steering mechanism, the steering motor does not directly drive the wheel fork to rotate, and therefore, the power of the steering motor can be reduced.
Because the wheel fork is in a vertical state, the poke rod is in a horizontal state, so that the poke rod and the wheel fork are in cross connection. Furthermore, the above solution does not allow the wheel fork and the driving wheel to rotate in situ by more than 180 °. Therefore, if the driving wheel needs to rotate in place by more than 180 degrees to realize the in-place steering of the movable base, a vertical motor shaft of the steering motor formed by the stepping motor can be directly connected with the wheel fork, or the vertical motor shaft of the steering motor formed by the stepping motor is in transmission connection with the wheel fork through a gear transmission mechanism.
