Description

Technical Field

[0001] This invention relates to the field of wall hanging base technology, specifically an easy-to-use assisted wall hanging base. Background Technology

[0002] The medical irrigation tower assist bracket (irrigation fluid bag pressurizer) is a medical device that uses mechanical assistance to adjust the height and stably pressurize the irrigation fluid bag. It is widely used in operating rooms, emergency departments, orthopedics, obstetrics and gynecology, and other departments. Its core functions are to improve irrigation efficiency, ensure surgical safety, and reduce the workload of medical staff. The bracket typically has a base with wheels, usually using high-strength, silent omnidirectional casters. These casters not only allow for flexible and effortless movement, enabling quick repositioning in spaces such as operating rooms and emergency rooms, but also maintain absolute stability when locked, preventing the device from sliding and affecting surgical procedures, thus providing efficient and safe irrigation support for medical staff.

[0003] The invention disclosed in CN111853495A is an instrument support base, which consists of a top plate, a bottom plate, and support rods. The top plate has a mounting hole in the center, and the lower end of the support rod is inserted into the mounting hole. Four support legs are provided between the top and bottom plates, with one end inserted between the top and bottom plates and the other end extending outwards in a radial structure. Four fixing bolts pass through the top and bottom plates, each bolt penetrating one end of a support rod. Each support rod can rotate horizontally around the four fixing bolts. This invention allows for adjustment of the support center of gravity according to the shape of the instrument being supported by rotating and adjusting the state of the four support legs, thereby improving the stability of the support.

[0004] While the aforementioned technical solution offers the advantage of improving support stability by adjusting the center of gravity, it suffers from significant drawbacks. Like traditional hanger bases, it uses wheels as ground-contact components, resulting in extremely limited contact area between the wheels and the ground. This makes it difficult to provide sufficiently stable support and significantly reduces its anti-tipping ability. When the upper side of the hanger is subjected to external force, the entire base, using the wheels as a fulcrum, is prone to tipping over, seriously threatening the safety of the equipment. Furthermore, the wheels used in this technical solution are all-purpose wheels, which have excessive freedom of movement. During pushing, these wheels are prone to deviation or rotation, especially when there are significant differences in sensitivity between some wheels and others. For example, some wheels rotate flexibly while others are relatively sluggish. During pushing, the base may shift towards the more sensitive wheels, making it difficult to follow the intended path. This not only increases the difficulty of operation but also may cause damage to the equipment due to collisions or other accidents, leading to numerous inconveniences. Therefore, to address these issues, a user-friendly assisted hanger base is proposed. Summary of the Invention

[0005] To address the technical problems in comparative technologies, such as the difficulty in providing stable support for the hanger base, particularly its poor performance in resisting tipping over, and the tendency for deviation or rotation during pushing, which causes numerous inconveniences in actual use, this invention provides an easy-to-use assist hanger base.

[0006] The technical solution adopted by the embodiments of this application to solve its technical problem is:

[0007] A user-friendly power-assisted hanging bracket base includes a base body with several multi-functional support components fixedly installed at its end. These multi-functional support components can switch between a moving state and a supported state. Each multi-functional support component includes a mounting base with a rotatably mounted flip-up anti-slip foot. A lockable swivel wheel is detachably mounted on each flip-up anti-slip foot. Symmetrically arranged multi-functional locking components are mounted on the mounting base. When the multi-functional support component is in a moving state, the flip-up anti-slip foot rotates and tilts upwards, and the lockable swivel wheel touches the ground. When the multi-functional support component is in a supported state, the flip-up anti-slip foot rotates and falls downwards, simultaneously touching the ground with the lockable swivel wheel.

[0008] In one possible implementation, the multifunctional locking component includes guides fixedly mounted on both sides of the mounting base, and a sliding rod slidably mounted on the mounting base and the guides, with a locking pin fixedly connected to its inner end.

[0009] In one possible implementation, a positioning magnetic base is fixedly provided at the junction of the slide bar and the locking pin, which can be attracted and connected to the outer wall of the mounting base and the guide frame respectively, and a lever is fixedly provided on the positioning magnetic base.

[0010] In one possible implementation, the flip-type anti-slip support includes a foot base with a hinge joint fixedly mounted on its upper side for rotatably connecting to the mounting base, and a ground-contacting fork fixedly mounted on its outer end. The inner end is machined with a groove for mounting a lockable omnidirectional wheel. A positioning connecting plate is fixedly mounted on the foot base. When the multi-functional support is in a supported state, the foot base is pressed against the lower end face of the mounting base, the locking pin is inserted into the positioning connecting plate, and the positioning magnetic seat is attached to the mounting base.

[0011] In one possible implementation, the bottom of the ground contact fork is provided with an anti-slip pad, and the lower end face is machined with a number of anti-slip patterns. The inner wall of the ground contact fork is fixedly provided with a number of snap-fit ​​protrusions, and the anti-slip pad is fixedly provided with a connector, which is machined with a number of slots that engage with the snap-fit ​​protrusions.

[0012] In one possible implementation, the lockable swivel wheel includes a mounting base detachably installed in a groove in the foot base, with several connecting bearings embedded inside, and a rotating shaft rotatably connected to the mounting base via the connecting bearings. A wheel cylinder is fixedly connected to one end of the rotating shaft, and rollers are rotatably connected to both ends of the rotating shaft.

[0013] In one possible implementation, the rotating shaft is provided with several angle locking slots arranged in a circular array. When the multifunctional support is in a moving state, if the positioning magnetic seat is attached to the mounting seat and the locking pin is inserted into the angle locking slot, the roller orientation is locked. By locking the orientation of some rollers, it can prevent the rollers from deviating and rotating due to excessive freedom of the wheel body when pushing the bracket. If the positioning magnetic seat is attached to the guide frame and the end of the locking pin separates from the angle locking slot and retracts into the mounting seat, the rotating shaft rotates freely and the roller orientation is free.

[0014] In one possible implementation, a magnetic suction plate is embedded in the hinge joint, and a limit plate is fixedly provided on the top of the mounting base. When the multifunctional support is in a moving state, the hinge joint and the limit plate are pressed together, and the magnetic suction plate is attracted to the limit plate.

[0015] In one possible implementation, a wheel bracket is fixedly provided at the end of the base body, which includes a support column. A positioning arc plate is fixedly provided at the bottom of the support column. When the multifunctional support is in a supporting state, the positioning arc plate is pressed and fitted against the upper side of the wheel cylinder.

[0016] In one possible implementation, when the multifunctional support is in a supported state, the lowest point of the roller is at the same level as the lower end face of the anti-slip pad.

[0017] In summary, the present invention has the following beneficial technical effects:

[0018] The multi-functional support design allows for flexible switching between mobile and supported states. Users can easily adjust the base to the appropriate state according to their actual needs, improving the applicability and ease of use of the rack. In mobile state, the flip-up anti-slip feet tilt up during movement, reducing friction with the ground and making pushing easier and less strenuous. The magnetic connection between the hinge joint and the limiting plate further ensures stability during movement. In supported state, the flip-up anti-slip feet and the lockable omnidirectional wheels simultaneously contact the ground, increasing the contact area and improving support stability. The extended flip-up anti-slip feet greatly enhance the rack's anti-tipping ability. The multi-functional locking component inserts the locking pin into the positioning connecting plate and fixes it to the mounting base via the magnetic positioning base, strengthening the connection between the flip-up anti-slip feet and the mounting base and preventing shaking and displacement.

[0019] Furthermore, when the multi-functional support is in a moving state, if the positioning magnetic base is attached to the mounting base and the locking pin is inserted into the angle locking groove, the roller orientation is locked. By locking the orientation of some rollers, it can prevent the rollers from deviating and rotating due to excessive freedom of movement when pushing the bracket. If the positioning magnetic base is attached to the guide frame and the end of the locking pin separates from the angle locking groove and retracts into the mounting base, the rotating shaft rotates freely and the roller orientation is free. The moving direction of the bracket base can be flexibly adjusted according to actual needs. Attached Figure Description

[0030] The technical solution in this application embodiment is to solve the problems mentioned in the background art, and the overall idea is as follows:

[0031] like Figure 1 - Figure 2 As shown, this embodiment provides a user-friendly assisted hanging bracket base, including a base body 1. Several multi-functional support members 2 are fixedly installed at the end of the base body 1. These multi-functional support members 2 can flexibly switch between a moving state and a supporting state to meet the needs of the hanging bracket equipment in different usage scenarios. Figure 2 In the image, the left side shows the multi-functional support component 2 in a moving state, while the right side shows it in a supporting state.

[0032] The multi-functional support component 2 includes a mounting base 3, which serves as the basic structure of the multi-functional support component 2 and provides mounting support for other components. A flip-type anti-slip support leg 4 is rotatably mounted in the mounting base 3. The flip-type anti-slip support leg 4 can rotate around the mounting base 3 to achieve position adjustment in different states. Lockable corner casters 5 are detachably mounted on the flip-type anti-slip support leg 4. The design of the lockable corner casters 5 allows the bracket base to flexibly change direction when moving. A symmetrically arranged multi-functional locking component 6 is installed on the mounting base 3. The multi-functional locking component 6 is used to lock the relevant components in different states to ensure the stability and reliability of the base.

[0033] The following is a detailed explanation of the movement and working principle of each component in two different working states of the base: the moving state and the supporting state.

[0034] First, let's introduce the core working component that connects the two different working states—the multi-functional locking component 6, such as... Figure 4As shown, the multifunctional locking component 6 includes guide frames 61 fixedly mounted on both sides of the mounting base 3. The guide frames 61 provide guidance for the sliding of the slide rod 62. The slide rod 62 is slidably mounted on the mounting base 3 and the guide frames 61. The slide rod 62 can slide linearly under the guidance of the guide frames 61. Its inner end is fixedly connected to a locking pin 63. The locking pin 63 is used to insert into the positioning hole or connecting plate of the relevant component to realize the locking function.

[0035] To ensure that the locking pin 63 does not slide out of position after reaching the designated position and thus affect its locking function, a positioning magnetic base 64 is fixedly provided at the junction of the slide rod 62 and the locking pin 63. The positioning magnetic base 64 can be magnetically connected to the outer wall of the mounting base 3 and the guide frame 61 respectively, enhancing the stability of the locking through magnetic attraction. A lever 65 is fixedly provided on the positioning magnetic base 64, which allows the user to manually operate the slide rod 62 to achieve locking and unlocking functions. When it is necessary to lock the relevant components, push the lever 65 to slide the slide rod 62, causing the locking pin 63 to be inserted into the corresponding position, while the positioning magnetic base 64 is magnetically fixed to the mounting base 3 or the guide frame 61. When it is necessary to unlock, pull the lever 65 to slide the slide rod 62 in the opposite direction, causing the locking pin 63 to retract from the corresponding position, and the positioning magnetic base 64 to separate from the magnetic surface.

[0036] Secondly, such as Figure 3 As shown, the flip-type anti-slip support 4 includes a foot base 41, which serves as the main structure of the flip-type anti-slip support 4 and bears the weight of the hanging equipment. A hinge joint 42 is fixedly installed on the upper side of the foot base 41 and is rotatably connected to the mounting base 3. The hinge joint 42 is rotatably connected to the mounting base 3, allowing the flip-type anti-slip support 4 to rotate flexibly. A ground contact fork 43 is fixedly installed at the outer end of the foot base 41, which increases the contact area with the ground and improves the support stability. A groove is machined at the inner end of the foot base 41 to install a lockable swivel wheel 5, providing installation space for the lockable swivel wheel 5.

[0037] To further improve the support stability of the ground contact fork head 43, such as Figure 8 As shown, the bottom of the ground contact fork 43 is provided with an anti-slip pad 46, which can effectively increase the friction between the fork and the ground and prevent the rack equipment from sliding under the support. The lower end surface of the anti-slip pad 46 is machined with several anti-slip textures to further enhance the anti-slip effect. Several snap-fit ​​protrusions 431 are fixedly provided on the inner wall of the ground contact fork 43, and a connector 461 is fixedly provided on the anti-slip pad 46. Several slots are machined on the connector 461 to engage with the snap-fit ​​protrusions 431. Through the snap-fit ​​cooperation between the snap-fit ​​protrusions 431 and the slots, the anti-slip pad 46 and the ground contact fork 43 can be quickly installed and removed, which is convenient for replacement and maintenance.

[0038] like Figure 3As shown, when the multi-functional support 2 is in the supported state, the flip-type anti-slip foot 4 rotates and falls down, simultaneously touching the ground with the lockable swivel wheel 5, providing stable support for the hanging equipment. At this time, the foot base 41 and the lower end face of the mounting base 3 are pressed and fitted together, and the locking pin 63 in the multi-functional locking component 6 is inserted into the positioning connecting plate 44 fixedly set on the foot base 41. The positioning magnetic seat 64 is attached to the mounting base 3, further enhancing the connection stability between the flip-type anti-slip foot 4 and the mounting base 3, preventing shaking or displacement during the support process. At the same time, the wheel bracket 7 fixedly set at the end of the base body 1 also plays a role, such as... Figure 5 As shown, the wheel bracket 7 includes a support column 71, and a positioning arc plate 72 is fixedly installed at the bottom of the support column 71. The positioning arc plate 72 is pressed and fitted against the upper side of the wheel cylinder 54, providing auxiliary support and positioning for the lockable swivel wheel 5, further improving the stability of the base in the supported state. It should be noted that when the multi-functional support 2 is in the supported state, the lowest point of the roller 55 is at the same level as the lower end surface of the anti-slip pad 46, ensuring that the hanging equipment is placed stably and will not wobble due to height differences.

[0039] like Figure 6 As shown, when the multi-functional support 2 is in a moving state, the flip-type anti-slip foot 4 rotates and tilts up, so that the lockable omnidirectional wheel 5 touches the ground. At this time, the bracket base can be moved easily. At this time, the hinge joint 42 and the limiting plate 31 are pressed and fitted together, and the magnetic suction plate 45 embedded in the hinge joint 42 is attracted and connected to the limiting plate 31 fixedly set on the top of the mounting base 3, which further ensures the stability of the flip-type anti-slip foot 4 in the moving state and prevents it from falling accidentally during the movement.

[0040] Among them, such as Figure 5 As shown, the lockable swivel caster 5 includes a mounting base 51 detachably installed in the groove of the foot base 41. The mounting base 51 provides a mounting foundation for other components of the lockable swivel caster 5. Several connecting bearings 52 are embedded inside the mounting base 51. The connecting bearings 52 are used to reduce friction between rotating parts and improve rotational flexibility. It also includes a rotating shaft 53, which is rotatably connected to the mounting base 51 through the connecting bearings 52, so that the rotating shaft 53 can rotate freely relative to the mounting base 51. A wheel cylinder 54 is fixedly connected to the end of the rotating shaft 53, and the wheel cylinder 54 provides mounting support for the rollers 55. Rollers 55 are rotatably connected to both ends of the wheel cylinder 54. The rollers 55 contact the ground to realize the movement function of the bracket base.

[0041] However, in actual use, due to the high degree of freedom of the casters, they are prone to veering off course or rotating during pushing, especially when the sensitivity of some casters differs significantly from that of other casters. Therefore, if... Figure 5As shown, the rotating shaft 53 has several angle locking grooves 56 arranged in a circular array. The angle locking grooves 56 are used to cooperate with the locking insert shaft 63 to lock the orientation of the rollers 55. When the multi-functional support 2 is in a moving state, if the positioning magnetic seat 64 is attached to the mounting seat 3 and the locking insert shaft 63 is inserted into the angle locking groove 56, the orientation of the rollers 55 is locked. By locking the orientation of some rollers 55, it is possible to prevent the wheels from shifting and rotating due to excessive freedom of movement when pushing the bracket. (Refer to...) Figure 7 In state A; if the positioning magnetic base 64 is attached to the guide frame 61, the end of the locking pin 63 separates from the angle locking groove 56 and retracts into the mounting base 3, then the rotating shaft 53 rotates freely, and the roller 55 can freely face the direction of movement. The direction of movement of the bracket base can be flexibly adjusted according to actual needs. (Refer to...) Figure 7 In state B. By locking some of the rollers 55 in the correct orientation, the rollers can be prevented from rotating out of position due to excessive wheel freedom when pushing the hanger, thus enabling the hanger to move stably in the predetermined direction and improving the accuracy and controllability of the movement.

[0042] The principle and process of using this invention:

[0043] I. Assembly Process

[0044] Install the mounting base 51 into the groove of the foot base 41, ensuring a secure connection; embed the connecting bearing 52 into the mounting base 51, and then rotatably connect the rotating shaft 53 to the mounting base 51 via the connecting bearing 52; fix the wheel cylinder 54 to the end of the rotating shaft 53, and then rotatably connect the roller 55 to both ends of the wheel cylinder 54 to complete the assembly of the lockable swivel wheel 5; fix the hinge joint 42 to the upper side of the foot base 41, and embed the magnetic plate 45 into the hinge joint 42; attach the anti-slip pad 46 to the bottom of the ground contact fork 43 via the plug 461 and the snap-fit ​​protrusion 431 on the inner wall of the ground contact fork 43 to complete the assembly of the flip-up anti-slip foot 4; rotatably connect the assembled flip-up anti-slip foot 4 to the mounting base 3 via the hinge joint 42.

[0045] The guide frame 61 is fixedly installed on both sides of the mounting base 3. Then, the slide rod 62 is slidably installed on the mounting base 3 and the guide frame 61. The locking pin 63 is fixedly connected to the inner end of the slide rod 62. The positioning magnetic seat 64 is fixedly installed at the junction of the slide rod 62 and the locking pin 63. The paddle 65 is fixedly installed on the positioning magnetic seat 64 to complete the assembly of the multi-functional locking component 6.

[0046] The assembled multi-functional support component 2 is fixedly installed to the end of the base body 1, and the support column 71 is fixedly installed to the end of the base body 1. The positioning arc plate 72 is fixedly installed at the bottom of the support column 71 to complete the installation of the wheel bracket 7 and finally complete the assembly of the entire power-assisted hanging bracket base.

[0047] II. Usage Method

[0048] Moving state: When it is necessary to move the rack equipment, manually push the flip-up anti-slip support 4 upward to make it rotate and tilt up. At the same time, push the lever 65 to make the slide bar 62 slide, which will drive the locking pin 63 to insert into the angle locking groove 56 on the rotating shaft 53, and make the positioning magnetic seat 64 adhere to the mounting base 3. At this time, the roller 55 is locked and the corner caster 5 touches the ground. The rack base is in the moving state, and the user can easily push the rack equipment to move.

[0049] Support Status: After moving the hanging rack equipment to the designated position, manually push down the flip-up anti-slip support foot 4 to make it rotate and fall down, simultaneously touching the ground with the lockable angle caster wheel 5. Then pull the lever 65 to make the slide rod 62 slide in the opposite direction, the locking pin 63 disengages from the angle locking groove 56, and the positioning magnetic seat 64 separates from the mounting base 3. Continue to push the lever 65 to make the locking pin 63 insert into the positioning connecting plate 44, and make the positioning magnetic seat 64 adhere to the mounting base 3. At this time, the foot base 41 is pressed against the lower end face of the mounting base 3, and the positioning arc plate 72 is pressed against the upper side of the wheel cylinder 54. The hanging rack base is in a supported state, providing stable and reliable support for the hanging rack equipment.

[0050] Finally, it should be noted that the above embodiments are merely examples for clearly illustrating the present invention and are not intended to limit the implementation. Those skilled in the art will recognize that other variations or modifications can be made based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations. However, obvious variations or modifications derived therefrom are still within the scope of protection of this invention.
