Description

TECHNICAL FIELD

[0001] The utility model belongs to the technical field of medical equipment, and particularly relates to a locking device and a moving device with the same. BACKGROUND

[0002] Moving devices are widely used in many fields, especially in the medical field. For example, a surgical bed has four casters, which can facilitate the pushing of a patient to a desired place. For another example, a trolley provided with casters is provided with medical equipment, such as an anesthetic or a surgical navigation device, which can be pushed to a desired place. In order to fix the moving device after reaching the predetermined position, so as to prevent it from moving, the moving device is provided with a locking device to lock the casters. The structure for locking a single caster is known. However, in the medical field, there are higher requirements for the locking of the moving device, because medical activities often require delicate operations, which require the moving device to be fixed quickly and reliably. If only one caster is locked, the reliable fixation of the moving device cannot be guaranteed, and if all casters are locked separately, since the positions of the caster locking plates are not unique, some caster locking plates are not easy to operate, thus being time-consuming and laborious, and one or more casters may be missed due to human operation.

[0003] Therefore, there is a need to improve the locking device of the moving device. SUMMARY

[0015] According to an aspect of the present application, the first manipulating device comprises a first member having a pedal, a second member connected to the first member, and a third member connected to the second member, the third member is connected to the first connecting rod in a non-rotatable manner, and the rotation direction of the first member and the third member is opposite.

[0016] According to one aspect of the present application, the first operating device further comprises a fourth member fixed to the support device, for providing support for the first member and the first connecting rod.

[0033] The technical solutions of the utility model will be described in detail below with reference to the drawings.

[0034] Embodiments of the utility model will be described below with reference to the drawings. In the following description, numerous specific details are set forth in order to provide a thorough understanding of the utility model and in order to enable one of ordinary skill in the art to implement the utility model. However, it will be apparent to one of ordinary skill in the art that the utility model can be implemented without some of these specific details. In addition, it should be understood that the utility model is not limited to the particular embodiments described. On the contrary, the utility model can cover any combination of the features and elements described below, whether they are involved in different embodiments or not. Therefore, the following aspects, features, embodiments and advantages are only for illustration and should not be regarded as features or limitations of the claims unless explicitly proposed in the claims.

[0035] In the following description, the description of orientation such as "upper", "lower", "inner", "outer", "radial", "axial" and the like, which can be used, unless explicitly stated, is only for the convenience of description, and does not intend to form any limitation on the technical solutions of the utility model. In addition, in the following, terms such as "first", "second" and the like are used to describe the elements of the present application, and these terms are only used to distinguish the respective elements, and do not intend to limit the nature, sequence, order or number of these elements.

[0036] Figure 1 A top view of the moving device of the utility model is shown. Figure 2 A bottom view of the moving device of the utility model is shown. From Figure 1 and Figure 2As can be seen from the diagram, the mobile device of this utility model includes a support device 10, a walking device 20, and a locking device 30. The support device 10 is used to provide support for other objects such as medical equipment, and at the same time, the support device 10 also provides a mounting base for the walking device 20 and the locking device 30.

[0037] The support device 10 is made of a material that meets strength requirements and has a body 11 and a walking device mounting part 12. It is used to support objects placed on it, such as medical equipment. The walking device mounting part 12 can also be used to mount the walking device 20. As a common practice, the support device 10 can be rectangular in shape, that is, the body 11 and the walking device mounting part 12 together form a rectangle. This is suitable for objects such as medical equipment with rectangular outlines, and the rectangular shape is also easy to process and manufacture.

[0038] However, the support device 10 can also have irregular shapes, such as Figure 1 The shape shown is such that the body 11 can be approximately rectangular, while the walking device mounting part 12 extends from the body 11. Of course, the body 11 can also have other regular shapes, such as triangles. When using this irregular shape, the object can be placed only on the body 11, not on the walking device mounting part 12. This allows for a more flexible installation method between the walking device 20 and the support device 10, and if maintenance or replacement of the casters is needed, the casters can be operated without moving the object. Furthermore, this irregular shape also allows for more flexible positioning of the walking device mounting part 12. The locking device proposed in this invention can be used not only for support devices 10 with simple shapes such as rectangles, but also for support devices 10 with irregular shapes.

[0039] The main body 11 may have multiple holes for connecting and fixing objects placed on it. The walking device 20 adopts the form of casters known in the prior art, and is mounted on the support device 10 through corresponding mounting structures such as holes on the walking device mounting part 12.

[0040] The mobile device of this utility model also includes a locking device 30, used to simultaneously lock or unlock all the casters in the walking device 20. Specifically, the locking device 30 includes... Figure 1 and Figure 2 The two pedals shown are part of the first control device 31 and the second control device 32, respectively. Figure 2 As shown, in order to protect the locking device, most of the structure of the locking device is encapsulated with a cover to prevent it from being touched by the outside world, which would affect the normal operation of the locking device or cause it to be damaged.

[0041] Figure 3 A bottom perspective view of the mobile device of the utility model is shown, wherein part of the cover is removed to better show the locking device. Figure 4 A top perspective view of the locking device of the utility model is shown separately. Figure 5 A partial top perspective view of the locking device of the utility model is shown. Figure 6 A partial perspective view of the locking device of the utility model from another angle is shown. Figures 3 to 6 The specific structure of the locking device is described in detail.

[0042] In Figure 3 , the structure of the walking device 20 is further shown, wherein the walking device comprises a caster body 21 and a connecting member 22 for connecting the caster body 21 to the support device 10, which can be clearly seen from Figure 6 . In addition, the connecting member 22 is also used to be connected with the locking device 30, so as to manipulate the brake member provided on the connecting member 22 for frictionally engaging with the caster body 21 through the locking device 30.

[0043] As Figure 4 shown, in the utility model, a first manipulating device 31 and a second manipulating device 32 are provided for locking or unlocking the casters. In order to be able to lock or unlock multiple casters at the same time, the first connecting rod 34 is used to transmit the manipulating action to the two casters on one side, and the linkage mechanism 35 is used to transmit the manipulating action to the second connecting rod 36 on the other side, so as to manipulate the two casters on the right side in the figure at the same time. Figure 4 In , the two casters on the left side are grouped as a group, and the two casters on the right side are grouped as a group, however, this is only an example, and the two casters on the upper side or the two casters on the lower side can also be grouped as a group, so as to manipulate them at the same time.

[0044] Figure 4 In , the fixing member 33 is also shown to fix the first manipulating device 31 and the second manipulating device 32 to the support device 10. In addition, other components of the locking device can also be connected to the support device 10 through threaded fasteners and the like, so as to provide positioning and support for these components.

[0045] Since the structures and locking modes of the locking devices adopted by the wheel groups on both sides are the same, the following Figure 5 is based on Figure 4 to describe the part on the left side. Referring to Figure 5For the first operating device 31 and the second operating device 32, when one of them is stepped down by the foot, the first connecting rod 34 can be rotated to the first direction to realize one of the locking and the unlocking of the caster; when the other one is stepped down by the foot, the first connecting rod 34 can be rotated to the second direction to realize the other one of the locking and the unlocking of the caster. When the first connecting rod 34 rotates, it can correspondingly rotate the linkage mechanism 35, and further rotate the second connecting rod 36.

[0046] Further, in order to make the locking mechanism of the utility model applicable to the special-shaped support device, especially Figure 1 It can be seen from the walking device mounting portion 12 extending obliquely from the body 11, referring to Figure 5 and Figure 6 It can be seen that an intermediate component 39 is further arranged between the first connecting rod 34 and the terminal operating part 38, so that there is an angle between the first connecting rod 34 and the terminal operating part 38 to adapt to the angle at which the walking device mounting portion 12 extends from the body 11. Especially from Figure 6 It can be seen that the intermediate component 39 comprises a first hinge joint arranged at one end of the first connecting rod 34, an intermediate hinge joint between the first connecting rod 34 and the terminal operating part 38, and a second hinge joint arranged at the corresponding end of the terminal operating part 38, thus forming two universal hinge mechanisms.

[0047] The two universal hinge mechanisms have the same structure and working mode. Here, the first hinge joint arranged at one end of the first connecting rod 34 and the intermediate hinge joint are taken as examples for illustration. As shown in Figure 6 The first hinge joint arranged at one end of the first connecting rod 34 can have two ears, and a square block can be arranged between the two ears, so that the square block can rotate around the axis of the two ears. The square block corresponds to an orthogonal coordinate system. The intermediate hinge joint has a hinge joint at each end, and each hinge joint has two ears, which are connected with the other two faces of the square block, so that the intermediate hinge joint can rotate in two directions of the orthogonal coordinate system relative to the first hinge joint and the first connecting rod 34, but cannot rotate in the third direction relative to the first hinge joint and the first connecting rod 34. Thus, first, since the intermediate hinge joint cannot rotate relative to the first hinge joint and the first connecting rod 34 in one direction, the power from the first connecting rod 34 can be transmitted through the intermediate hinge joint in this direction, so as to realize the locking or unlocking of the caster; second, since the intermediate hinge joint can rotate relative to the first hinge joint and the first connecting rod 34 in two directions, the spatial positional relationship between the intermediate hinge joint and the first connecting rod 34 is very flexible, and can be set as required.

[0048] Similarly, the end manipulator 38 and the intermediate joint also have corresponding structures and working modes.

[0049] Thus, the end manipulator 38 can be in the same plane as the first link 34, and the angle between the end manipulator 38 and the first link 34 can be adjusted by rotating the end manipulator 38 in one direction. Alternatively, the end manipulator 38 can be in a different plane from the first link 34, which can be achieved by rotating the end manipulator 38 in another direction. In any case, the end manipulator 38 can transmit the rotation from the first link 34 to lock or unlock the casters.

[0050] This universal connection greatly improves the flexibility of the structure of the support device 10. For example, the walking device mounting portion 12 can be in the same plane as the body 11, but extend from the body 11 in an inclined manner, and different walking device mounting portions 12 can extend at different angles, or in different planes, i.e., upward or downward relative to the plane in which the body 11 is located.

[0051] Figure 6 Also shown in FIG. 6 is a support 37 for rotatably supporting the end manipulator 38. The support 37 is fixed to the support device 10, for example, by a threaded fastener, and the end manipulator 38 can pass through the support 37 and rotate relative to the support 37, but cannot move axially relative to the support 37. The end manipulator 38 is provided with a recess on both sides adjacent to the support 37, and a spacer or the like is provided in the recess to axially limit the end manipulator 38 relative to the support 37. The first link 34 can also use the same support. The end manipulator 38 extends into the walking device 20 at one end, and rotation of the end manipulator 38 can be transmitted to the internal mechanism of the walking device 20 to lock or unlock the walking device 20.

[0052] In combination Figure 5 and Figure 6 When the first and second manipulators 31 and 32 are manipulated to rotate, the first link 34 is rotated in opposite directions, and in addition to rotating the end manipulator 38 on one side through the universal connection mechanism described above, the first link 34 also rotates the linkage mechanism 35, which in turn rotates the second link 37 on the other side, thereby locking or unlocking the set of casters on the other side. As a possible implementation, as shown in FIG. 7, the linkage mechanism 35 can be a lever, and the second link 37 can be a rod that is rotatably connected to the lever. Figure 6As shown, the linkage mechanism 35 comprises a first part connected to the first link 34 and unable to rotate relative to the first link 34, a second part in the form of a rod connected to the first part, and a third part at the other end of the second part and arranged on the second link 36. As a preferred embodiment, the first link 34 and the second link 36 as well as the end manipulator 38 all have a hexagonal cross section, so that the power can be better transmitted and the normal locking and unlocking is not affected by the relative rotation.

[0053] Figure 7 A perspective view of a first manipulator of the locking device of the utility model is shown. Figure 8 A perspective view of a second manipulator of the locking device of the utility model is shown. For the first manipulator 31 and the second manipulator 32, both are connected to the first link 34 through respective linkage mechanisms, so that when one of the manipulators is manipulated, the other one will move accordingly. However, for any one of the manipulators, the action taken by the operator is to step down, without the need to stretch the foot under the pedal to lift the pedal upward with the instep, which simplifies the operation mode. When one of them is stepped down, the locking can be realized, and when the other one is stepped down, the locking can be released.

[0054] Specifically, referring to Figure 7 , the first manipulator 31 comprises a first member 31c having a pedal, the first member 31c is connected to a second member 31b, and the second member 31b is connected to the first link 34 through a third member 31a. As can be seen from Figure 7 , a rotation shaft is arranged on the pedal, and the first member 31c can rotate around the rotation shaft. When the pedal is stepped down, the first member 31c rotates counterclockwise around the rotation shaft, thereby driving the second member 31b to move upward, and further driving the third member 31a to rotate clockwise, and the first link 34 also rotates clockwise. This movement of the first manipulator 31 corresponds to one of the locking or the releasing.

[0055] The first manipulator 31 can further comprise a fourth member 31d for providing support for the first member 31c and the first link 34.

[0056] Referring to Figure 8 , the second manipulator 32 comprises a fifth member 32c having a pedal, the fifth member 32c is connected to a sixth member 32b, and the sixth member 32b is connected to the first link 34 through a seventh member 32a. As can be seen from Figure 8As can be seen, the pedal is provided with a rotating shaft, and the fifth member 32c can rotate around the rotating shaft. When the pedal is stepped on, the fifth member 32c rotates counterclockwise around the rotating shaft, thereby driving the sixth member 32b to move upward to the right, and further driving the seventh member 32a to rotate counterclockwise, and the first connecting rod 34 also rotates counterclockwise. This movement of the second operating device 32 corresponds to the other of the locking or the unlocking.

[0057] The second operating device 32 can further include an eighth member 32d for providing support for the fifth member 32c and the first connecting rod 34.

[0058] The first operating device 31 and the second operating device 32 are not directly connected to the first connecting rod 34 by pedals, but a connecting rod mechanism is adopted, so that more labor can be saved.

[0059] The utility model has been clearly and completely explained with reference to the above-mentioned illustrative embodiments, and those skilled in the art should understand that various other embodiments can be conceived by modifying the disclosed technical solutions without departing from the spirit and scope of the utility model. These embodiments should be understood to fall within the scope of the utility model as defined by the claims and any equivalent technical solutions thereof.
