Description
Technical Field
The invention relates to the technical field of medical instrument manufacturing, in particular to a convenient-to-use infusion device.
Background
At present, transfusion is a common medical means, the basic principle is that liquid medicine is filled in transfusion containers such as transfusion bottles, transfusion bags and the like, one end of a plastic transfusion tube is inserted into a sealing position of the transfusion bottle or the transfusion bag through a connecting end (usually a connecting needle head) so as to enable the transfusion tube to be communicated with the liquid medicine in the transfusion bottle or the transfusion bag, the other end of the transfusion tube is connected with the transfusion needle head which is used for being connected with an arm of a patient, and a dripping speed control valve is further arranged in the middle of the transfusion tube so as to regulate and control the transfusion speed. When in transfusion, the transfusion needle is connected with the vein of the hand of a patient lying on a sickbed or a chair, and the transfusion bottle or the transfusion bag is hung on a transfusion bracket at a high position, so that the transfusion needle can be dripped into the vein of the patient by means of the potential energy of the liquid medicine.
However, the existing infusion device has the following inconvenience in the use process: firstly, in order to ensure normal operation of infusion, an infusion container needs to be hung on a higher infusion support, and in the infusion process, when a patient needs to walk to go to a toilet, the patient needs to help a attendant to lift the infusion container (playing a role similar to that of the infusion support), and the patient can use one hand to lift the infusion container, but when the patient reaches the toilet, the patient cannot lift the infusion container by hand. The wall of the toilet is specially provided with a hook, and when a patient enters the toilet, the infusion container can be hung on the hook to vacate hands to solve the problem of toilet. However, this solution still fails to meet the requirement that the patient for some reason need to leave the infusion site such as the ward. That is, existing infusion devices typically require a caregiver to accompany the patient. Once the accompanying person leaves temporarily, the patient can be inconvenient to move. Secondly, because the connecting end of the infusion tube is inserted into the sealing position of the infusion bottle or the infusion bag, and the infusion needle of the infusion tube is inserted into the hand of a patient and positioned through the viscose tape, although the infusion tube is convenient for the operation of medical staff during infusion, the connection is not reliable enough, when the patient, or other medical staff and even accompanying staff carelessly touch the infusion tube, then drag the infusion tube, the problem that the connecting needle falls off from the sealing position of the infusion bottle or the infusion bag, or the infusion needle is pulled out from the hand of the patient easily occurs, and then expensive medicines are wasted, and if the problem is not found in time, the problem that the air lock of the patient is caused by vein air inlet is also likely to occur.
Disclosure of Invention
The invention aims to provide the infusion device which is convenient to use, on one hand, a patient can walk freely on the premise of no accompanying person, and on the other hand, the separation of an infusion tube and an infusion container or the hands of the patient can be effectively avoided during infusion, and the safety of infusion is ensured.
In order to achieve the above purpose, the present invention adopts the following technical scheme:
the utility model provides an infusion set who facilitates use, including being used for hanging infusion support, transfer line of infusion container, the one end of transfer line be equipped with the link that seals the department of infusion container pegging graft, the other end of transfer line is equipped with the infusion syringe needle, still be equipped with the drip speed control valve of control infusion speed on the transfer line, still including the removal base that has the removal wheel, vertically set up the lifter on removing the base, the upper end of lifter is equipped with the butt joint strip, the suspension end of butt joint strip upwards inclines, the removal base is equipped with the actuating mechanism who controls the lifter and goes up and down, the drive removes the actuating mechanism of base through the power unit who removes the wheel walking, the control part of base direction of movement is removed in the control, the infusion support includes the slide rail of downward sloping, the infusion container includes the movable sliding part that is located the slide rail, be equipped with the stop gear who prevents the outside removal of sliding part at the low end of slide rail, be equipped with anti-bracing piece on the transfer line, the first connecting portion of connecting on the infusion container is for the extension to be connected to the piece on the transfer line, the other end is the second connecting portion of connecting at patient's hand, when the patient need walk, actuating mechanism makes the lifter extend, the slide rail until the suspension end of butt joint strip goes up the actuating mechanism moves the control part to the control part of the control piece and reaches the control part that the infusion container of the control side of the position of the butt joint strip to arrive at the moment, when patient need to move the control part of the position of the control part of the control of the base that the butt joint strip to go down.
The infusion tube comprises an infusion tube, one end of the infusion tube is provided with a connecting end which is spliced with a 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 dripping speed control valve for controlling infusion speed. When transfusion is needed, the connecting end can be spliced with the sealing part of the transfusion container, then the transfusion needle is connected with the hand vein of a patient, and the liquid medicine in the transfusion bottle or the transfusion bag can be dripped into the vein of the patient by adjusting the dripping speed control valve.
Unlike the prior art, the infusion support of the present invention includes a slide rail and the infusion container includes a slide movably positioned on the slide rail. That is, the transfusion container can move transversely on the slide rail, and because the slide rail inclines downwards, the transfusion container automatically slides to the lower end outside 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 patient needs to leave original infusion position, accessible actuating mechanism makes the lifter extend to and is as high as the infusion container, until the suspension end butt joint slide rail of the butt joint strip of lifter upper end tilt up's suspension end, stop gear action this moment releases the sliding part of infusion container, the infusion container automatically slides down and gets into the butt joint strip, the patient can remove the base through the control part control and need the position that arrives to the patient, and then drive the infusion container through the lifter and arrive everywhere along the patient, make things convenient for the walking of infusion patient.
It should be noted that, the control unit may be used to control the movement of the mobile base by using the existing wireless control technology like a remote control car, so as to facilitate the control of the patient.
In addition, the invention also comprises a tensile bar arranged on the infusion tube, one end of the tensile bar is a first connecting part connected to the infusion container, and the other end is a second connecting part connected to the hand of a patient. Thus, when a patient, or other medical care or even accompanying personnel carelessly touches the infusion tube, and then pulls the infusion tube, the infusion tube is stressed by the anti-bracing strip, so that the separation of the infusion tube and the infusion container, or the pulling of the infusion needle from the hand of the patient can be effectively avoided. It will be appreciated that the effective length of the tension strip between the first and second connection portions is shorter than the effective length of the infusion tube to ensure that the tension strip is forced prior to the infusion tube. Of course, we should make the second connecting portion form the detachable connection with patient's hand, make first connecting portion form the detachable connection with infusion container, both conveniently connect, conveniently demolish again, promote medical personnel's work efficiency in succession.
Preferably, the lifting rod is a multi-stage oil cylinder, comprising an outer cylinder sleeve connected with the movable base, a plurality of lifting sleeves capable of being sleeved in the outer cylinder sleeve in a lifting manner, and a piston rod arranged in the innermost lifting sleeve, wherein the butt joint strip is arranged at the upper end of the piston rod, a hydraulic oil tank is arranged in the movable base, an oil motor is arranged on the movable 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 with the multi-stage oil cylinder.
It is known that a cylinder is a simple telescopic mechanism in the prior art, and the existing cylinder generally 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 lifting rod is about 1.8m, when the lifting rod adopts an oil cylinder structure, the initial length of the lifting rod may be about 1m, so that the lifting rod is inconvenient to store and use. The lifting rod is a multi-stage oil cylinder, and particularly comprises an outer cylinder sleeve connected with a movable base, a plurality of lifting sleeves which are sleeved in the outer cylinder sleeve in a lifting manner, and a piston rod arranged in the innermost lifting sleeve. That is, the cylinder block therein includes the outer cylinder jacket and the plurality of lifting jackets, so that the initial length of the entire lifting rod 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 extends out of the lifting sleeve at the innermost layer, the lifting sleeve at the inner layer extends out of the lifting sleeve at the outer layer, and the lifting sleeve is lifted out of the outer cylinder sleeve. Of course, we can set up the radial flange ring that expands outward in the lifting sleeve lower extreme of inlayer, set up spacing throat in outer lifting sleeve upper end. When hydraulic oil is input into the lifting rod, the lifting sleeve of the inner layer can lift up to the lifting sleeve of the outer layer until the flange ring of the lifting sleeve of the inner layer is positioned against the necking of the lifting sleeve of the outer layer.
It will be appreciated that the height of the docking bar and the hanging height of the infusion container are not a very well defined datum, and that, therefore, one can extend the lifting rod as far as possible until the docking bar abuts the rail from the underside. Of course, we can also set a normally open position switch at the end of the abutment. When 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.
Preferably, the tensile bar is provided with a plurality of lantern rings sleeved on the infusion tube at intervals along the axial direction, 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 the patient and is connected into a ring sleeve shape through the magic tape.
The lantern ring makes anti brace and transfer line form side by side structure, on the one hand, the transfer line can be pulled by mistake simultaneously with the tensile strip to ensure that anti brace can effectually share the atress of transfer line, on the other hand, ensure that the transfer line can freely move about relative tensile strip. It should be noted that, the second connecting portion of anti brace can set up corresponding magic subsides, and when second connecting portion encircleed in the wrist department of disease, second connecting portion accessible magic subsides connect into the loop cover shape reliably, both conveniently connect and demolish, ensure the reliable of connection again.
Preferably, the movable base is disc-shaped, 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 hub motor, the other of the wheels is a universal wheel, the driving wheel comprises a wheel fork rotationally connected with the movable base and a steering mechanism for driving the wheel fork to rotate, when the movable base needs to move, the hub motor drives the driving wheel to rotate so as to enable the movable base to advance or retreat, and the rotating mechanism controls the rotation of the wheel fork and then controls the movement 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 contacts 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 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 rotationally connected with the positioning rod, so that when the movable base needs to turn around at a large angle, the movable base can stop moving firstly, then the center of the movable base is positioned through the positioning rod, then the movable base is rotated in situ at a required angle, and then the positioning rod is contracted and the driving wheel is restarted, so that the movable base moves forwards. Of course, we can set up a motor on the removal base, and the output shaft of motor is connected with the locating lever, and when the locating lever made the removal base location, can start the motor, the removal base of this moment can rotate relative to the locating lever.
In addition, the invention is provided with a driving wheel and 2-3 universal wheels at the lower side of the movable base, so that when the driving wheel operates to drive the movable base to move, the direction of the rest universal wheels can be automatically adjusted. That is, the direction of the moving 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 poking rod, the poking rod comprises an inner rod connected with the wheel fork in a cross manner and an outer rod sleeved on the inner rod, a motor shaft of the steering motor is connected with a screw rod, a driving sleeve is connected to the screw rod in a threaded manner, 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, then the outer rod is driven to rotate, so that the wheel fork rotates, and the outer rod moves axially relative to the inner rod to automatically adjust the length of the poking rod.
When the movable base is required to turn, the steering motor can be started to drive the screw rod to rotate, so that the driving sleeve axially moves, and the steering rod drives the wheel fork and the driving wheel to rotate to change the direction. It can be appreciated that when the toggle rod rotates, the movement of the hinge point of the toggle rod and the driving sleeve is arc-shaped. Therefore, the invention enables the poke rod to comprise the inner rod and the outer rod which can move relatively, thereby avoiding the poke rod from interfering with the driving sleeve. In addition, because the driving sleeve is hinged with the poking rod, the driving sleeve can not rotate along with the screw rod, so that the driving sleeve can be ensured to move forwards and backwards. Of course, we can provide bearing blocks on the mobile base to support both ends of the screw.
Therefore, the invention has the following beneficial effects: on one hand, the patient can walk freely without accompanying personnel, and on the other hand, the separation of the infusion tube and the infusion container or the hands of the patient can be effectively avoided during infusion, so that the safety of infusion is ensured.

Detailed Description
The invention is further described below with reference to the drawings and detailed description.
As shown in figure 1, the infusion device convenient to use comprises an infusion support 1 for hanging an infusion container and an infusion tube 3, wherein one end of the infusion tube is provided with a connecting end (usually a connecting needle) which is inserted into a sealing part of the infusion container, the other end of the infusion tube is provided with the infusion needle, and the infusion tube is also provided with a dripping speed control valve 31 for controlling the infusion speed. When transfusion is needed, the connecting end can be spliced with the sealing part of the transfusion container 2 such as a transfusion bottle or a transfusion bag, then the transfusion needle is connected with the hand vein of a patient, and the dripping speed control valve is regulated, so that the liquid medicine in the transfusion bottle or the transfusion bag can be dripped into the vein of the patient.
In order to facilitate the patient to walk by himself when in transfusion, as shown in fig. 2, the invention also comprises a movable base 4 with movable wheels and a lifting rod 5 vertically arranged on the movable base, wherein the upper end of the lifting rod is provided with a butt joint strip 51, and the suspension 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 movable base is provided with a driving mechanism for controlling the lifting rod to lift up and down, a power mechanism for driving the movable base to walk through the movable wheels, and a control part for controlling the moving direction of the movable base. In addition, the transfusion support comprises a downward inclined slide rail 11, the transfusion container comprises a sliding part 21 movably arranged on the slide rail, and when a medical staff slidingly connects the sliding part of the transfusion container on the slide rail, the transfusion container can automatically slide to the lower end of the slide rail under the action of self gravity. Of course, a limiting mechanism capable of preventing the sliding part from moving outwards is arranged at the lower end of the sliding rail, so that the infusion container is reliably positioned at the lower end of the sliding rail.
When a patient needs to leave the original transfusion position and walk, the lifting rod can be extended to be as high as the transfusion container through the driving mechanism until the suspension end of the butt joint strip which is inclined upwards at the upper end of the lifting rod is abutted against the suspension end of the sliding rail, at the moment, the limiting mechanism acts to release the sliding part of the transfusion container, the transfusion container automatically slides downwards to enter the butt joint strip, the patient can move to the position which the patient needs to reach through the control part control moving base, and the lifting rod at the moment becomes a movable transfusion bracket which can reach any place along with the patient.
It should be noted that, the control part can be used for controlling the movement of the movable base in a wired or wireless control mode similar to a remote control car, thereby being convenient for independent control of patients. In addition, the invention can be provided with a general controller for controlling the expansion 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 sliding rail and is approximately vertical, an avoidance groove 112 which is communicated with the limiting hole is arranged at the end part of the sliding 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 downwards out of the limiting hole, a limiting ring 73 is arranged between the control section and the stop pin, a moving section 113 with an 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 compression spring 74 which downwards presses the limiting ring is arranged in the moving section.
In the initial state, the pressure spring drives the stop pin to move downwards to retract into the limit hole through the limit ring, the lower part of the limit section at the moment is positioned in the limit hole, the upper part of the limit section stretches out of the limit hole, and the sliding part of the infusion container moves outwards along the sliding rail to be positioned against the limit section. When a patient needs to leave the original transfusion position to walk, the lifting rod ascends, the suspension end of the butt joint strip with the upper end inclined upwards is abutted against the control section at the lower side of the suspension end of the sliding rail, so that the stop pin moves upwards, and at the moment, the limiting section hinged with the stop pin rotates outwards under the action of the transfusion container and is trapped in the avoidance groove. At this time, the sliding part of the transfusion container can continue to slide outwards along the sliding rail and enter the butt joint strip. Of course, a slope may be provided at the end of the rail to facilitate smooth transition of the infusion container to the docking head.
It will be appreciated that patients often need to continuously infuse several bottles or bags of medication, that is, 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 of the straight rod, wherein one end of the cross rod is a sliding rail inclined downwards, and the other end of the cross rod is used for hanging an infusion container to be infused. When 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 to continue the transfusion.
Preferably, a pulley with a hook is arranged on the sliding rail, a net bag is arranged on the outer side of the hard infusion bottle, and a hanging ring is arranged on the net bag; or a hanging hole is arranged on the flexible infusion bag. When in transfusion, the transfusion container can be smoothly slipped to the lower end of the sliding rail by only hanging the hanging ring or the hanging hole of the transfusion container on the hanging hook of the pulley.
It should be noted that, the pulley with the hook and the corresponding sliding rail may refer to the existing curtain rail structure, and will not be described in detail in this embodiment.
In addition, as shown in fig. 5, an anti-pulling strip 32 may be disposed on the infusion tube, where one end of the anti-pulling strip is a first connection portion connected to the infusion container, and the other end is a second connection portion (not shown) connected to the patient's hand.
Thus, when a patient, or other medical care or even accompanying personnel carelessly touches the infusion tube, and then pulls the infusion tube, the infusion tube is stressed by the anti-bracing strip, so that the separation of the infusion tube and the infusion container, or the pulling of the infusion needle from the hand of the patient can be effectively avoided. It will be appreciated that the effective length of the tension strip between the first and second connection portions is shorter than the effective length of the infusion tube to ensure that the tension strip is forced prior to the infusion tube. Of course, we should make the second connecting portion form the detachable connection with patient's hand, make first connecting portion form the detachable connection with infusion container, both conveniently connect, conveniently demolish again, promote medical personnel's work efficiency in succession.
Preferably, the first connecting portion includes a flexible winding belt, when infusion is required, the winding belt can be adhered to the outer side of the infusion container through double faced adhesive tape, or the winding belt can be adhered to the outer side of the infusion container through magic tape winding, even, the first connecting portion can be provided with a connecting hook, and a connecting hanging hole is formed in the infusion container. 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 can be reliably connected. The present invention is not focused on such connection, and thus, detailed description is not made in this embodiment.
Further, the anti-bracing piece is provided with a plurality of collars 321 sleeved on the infusion tube at intervals along the axial direction, of course, the collars are fixedly connected with the anti-bracing piece, the diameters of the collars can be reduced as much as possible, and the infusion tube can slide freely in the collars. 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 the patient and is connected into a loop shape through a magic tape.
The lantern ring makes anti brace and transfer line form side by side structure, on the one hand, the transfer line can be pulled by mistake simultaneously with the tensile strip to ensure that anti brace can effectually share the atress of transfer line, on the other hand, ensure that the transfer line can freely move about relative tensile strip. That is, when the anti-pulling strip and the infusion tube are simultaneously pulled, the infusion tube is in an 'unstressed state' capable of sliding freely relative to the anti-pulling strip, so that the infusion tube can be effectively prevented from being separated from the infusion container or the wrist of a patient. It should be noted that, the second connecting portion of anti brace can set up corresponding magic subsides, and when second connecting portion encircleed in the wrist department of disease, second connecting portion accessible magic subsides connect into the loop cover shape reliably, both conveniently connect and demolish, ensure the reliable of connection again.
As a preferable scheme, as shown in FIG. 6, the lifting rod is a multi-stage oil cylinder, and specifically comprises an outer cylinder sleeve 52 connected with a movable base, a plurality of lifting sleeves 53 which are liftably sleeved in the outer cylinder sleeve, and a piston rod 54 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 movable base, an oil motor is arranged on the movable 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 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.
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 extend upwards to the lifting sleeve at the innermost layer, the lifting sleeve at the inner layer extends to the lifting sleeve at the outer layer, and the lifting sleeve is lifted out of the outer cylinder sleeve. Of course, we can set up the flange ring 531 that radially expands outward in the lifting cover lower extreme of inlayer to set up the sealing washer on the flange ring, in order to realize the sealing between flange ring and the outer lifting cover. That is, the flange ring at this time acts like a piston. In addition, a limiting constriction 532 is provided at the upper end of the outer lifting sleeve. When hydraulic oil is input into the lifting rod, the lifting sleeve of the inner layer can lift up to the lifting sleeve of the outer layer until the flange ring of the lifting sleeve of the inner layer is positioned against the necking of the lifting sleeve of the outer layer.
It should be noted that, by reasonably setting the diameter of each layer of lifting sleeve and the area parameters of the corresponding flange ring, the elongation of the lifting rod is ensured according to the following sequence when hydraulic oil with pressure is input into the multistage oil cylinder: the wire extends out of the piston rod, then extends out of the innermost lifting sleeve on the outer side of the piston rod, and then sequentially extends out of all layers of lifting sleeves from inside to outside.
To control the extension height of the lifter, we can provide a normally open position switch at the end of the butt-strap and associate the position switch with the oil motor. When the lifting rod stretches and the butt joint strip abuts against the sliding rail from the lower side, the position switch is started, and therefore the oil motor is stopped through the controller.
Further, the movable base is disc-shaped, a positioning rod 41 capable of lifting is vertically arranged in 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 part. In addition, 3-4 wheels 43 are uniformly distributed in the circumferential direction at the lower side edge of the movable base, one of the wheels is a driving wheel with an in-wheel motor, the other is a follow-up universal wheel, and the driving wheel comprises a fork rotationally connected with the movable base and a steering mechanism for driving the 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 is enabled to move forwards or backwards. Of course, the positioning rod is in a contracted state, and the positioning disc at the lower end of the positioning rod is separated from the bottom surface. Meanwhile, the rotation of the wheel fork can be controlled through the rotating mechanism, so that the moving direction of the driving wheel and the moving base can be controlled; when the movable base needs to stop positioning, the controller stops the hub motor and the driving wheel on one hand, and enables the positioning rod to extend downwards on the other hand, and then enables the positioning disc to contact the ground for positioning.
It will be appreciated that when the drive wheel is operated to move the mobile base, the remaining universal wheels will automatically adjust direction. That is, the direction of the moving 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 movable base needs to turn around or even turn around at a large angle, the movable base can be stopped to move, then the center of the movable base is positioned through the positioning rod, then the movable base can be rotated in situ by a required angle through the driving wheel, the positioning rod is retracted, and the driving wheel is restarted, so that the movable base can move forwards.
Alternatively, as shown in fig. 7, a motor 44 may be fixed on the movable base, the output shaft of the motor is connected with the positioning rod, and a threaded sleeve 45 connected with the positioning rod in a threaded manner is arranged on the movable base. When the motor is running, the positioning rod can extend downwards or retract upwards. When the positioning rod extends downwards to the position where the positioning disc abuts against the ground to be positioned, the motor continues to rotate, the positioning disc cannot continue to rotate at the moment, and the movable base and the motor generate rotation relative to the positioning rod and the positioning disc, so that the in-situ steering of the movable base is realized. Of course, the positioning disc and the positioning rod are fixedly connected, and the output shaft of the motor and the positioning rod can be inserted through a spline or a regular hexagon jack and a bolt, so that the positioning rod moves relative to the output shaft.
In order to facilitate the turning of the movable base, as shown in fig. 8, the turning mechanism comprises a turning motor 6 and a toggle rod 61, wherein the toggle rod comprises an inner rod 611 which is in cross connection with a fork 431 and an outer rod 612 which is sleeved on the inner rod, a motor shaft of the turning motor is connected with a screw rod 62, a driving sleeve 63 is in threaded connection with the screw rod, and the middle part of the outer rod is hinged with the middle part of the driving sleeve. When the steering motor drives the screw rod to rotate, the driving sleeve moves along the axial direction, and then drives 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 is required to turn, the steering motor can be started to drive the screw rod to rotate, so that the driving sleeve axially moves, and the steering rod drives the wheel fork and the driving wheel to rotate to change the direction. It can be appreciated that when the toggle rod rotates, the movement of the hinge point of the toggle rod and the driving sleeve is arc-shaped. Therefore, the invention enables the poke rod to comprise the inner rod and the outer rod which can move relatively, thereby avoiding the poke rod from interfering with the driving sleeve. In addition, because the driving sleeve is hinged with the poking rod, the driving sleeve can not rotate along with the screw rod, so that the driving sleeve can be ensured to move forwards and backwards. Of course, we can provide bearing blocks on the mobile base to support both ends of the screw. Of course, the steering motor may employ a stepping motor to precisely control the rotation direction thereof.
It will be appreciated that in the steering mechanism described above, the steering motor does not directly drive the fork to rotate, and therefore the power of the steering motor can be reduced.
Because the wheel fork is in a vertical state, the poking rod is in a horizontal state, so that the poking rod and the wheel fork are in cross connection. Furthermore, the above solution does not allow the fork and the drive wheel to be turned in situ more than 180 °. Therefore, if the driving wheel needs to rotate more than 180 degrees in situ to realize the in situ steering of the movable base, the 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 can be in transmission connection with the wheel fork through the gear transmission mechanism.
