Description
Technical Field
[0001] This utility model relates to the technical field of bridge construction, specifically to a reverse auxiliary structure for hanging basket travel. Background Technology
[0002] Using a formwork (also known as a cantilever formwork) for cantilever construction is a common method in bridge construction. During construction, the formwork needs to move along the main girder of the bridge, which is called formwork travel. The design of the traveling structure and the control of the operating speed are crucial in this process.
[0003] Because the hanging basket itself is a large structure, and usually has a large amount of construction materials such as formwork, steel bars, and concrete suspended at the front, its overall center of gravity is forward. If the walking speed is too fast, it will generate a large inertial force, and the center of gravity may move beyond the support point, causing it to tilt forward or overturn entirely.
[0004] The existing method uses speed limiting devices to prevent the formwork from overturning due to excessive travel speed. However, when the formwork moves at a high speed and suddenly stops or changes direction, inertial forces act on the front end of the structure, easily causing structural instability. This risk is even greater when the formwork is not fully fixed or the bridge deck structure is not fully formed, easily leading to instability of the center of gravity and overturning, thus posing a significant risk during use. Utility Model Content
[0005] This invention provides a reverse walking auxiliary structure for hanging baskets to solve the above-mentioned technical problems.
[0006] To achieve the above objectives, this utility model provides a reverse walking auxiliary structure for hanging baskets, comprising:
[0007] The main body of the hanging basket has a walking structure, and the walking structure is equipped with a gravity connecting beam;
[0008] A support frame is located at the end of the main body of the hanging basket that is furthest from the hanging basket.
[0009] A telescopic drive component, one end of which is fixed to the support frame;
[0010] A movable limiting arm is rotatably connected at one end to the support frame and at the other end to the telescopic drive member away from the support frame. A limiting space is formed between the movable limiting arm, the support frame, and the telescopic drive member. The gravity connecting beam is located within the limiting space.
[0011] When the main body of the hanging basket moves, it drives the gravity connecting beam to move within the limited space to limit the movement stroke of the gravity connecting beam. When the center of gravity of the main body of the hanging basket is unstable, the movable limiting arm provides a reverse pulling force.
[0012] Preferably, the movable limiting arm includes:
[0013] The first connecting arm has a first arm and a second arm rotatably connected to one end of the first arm. The end of the first arm away from the second arm is rotatably connected to the support frame, and the end of the second arm away from the first arm is rotatably connected to the telescopic drive member.
[0014] Preferably, the movable limiting arm further includes:
[0015] An auxiliary connecting arm has a third arm and a fourth arm rotatably connected to one end of the third arm. The end of the third arm away from the fourth arm is rotatably connected to the middle of the first arm, and the end of the fourth arm away from the third arm is rotatably connected to the middle of the second arm.
[0016] When the main body of the hanging basket moves, the movable limiting arm forms a quadrilateral structure. When a reverse pulling force is required, a triangular structure is formed between the movable limiting arm, the support frame, and the telescopic drive component.
[0017] Preferably, the support frame has a movable groove, one end of the movable limiting arm is received in the movable groove and is rotatably connected to the support frame.
[0018] Preferably, the movable groove is provided with a limiting area and a reverse tension area;
[0019] The movable limiting arm can move within the limiting area or the reverse pulling area.
[0020] Preferably, the basket walking reverse auxiliary structure further includes:
[0021] The first contact switch is located in the movable slot and is rotatably connected to the support frame.
[0022] The second contact switch is located within the reverse pulling force area;
[0023] When the device is in a limiting position, the movable limiting arm rotates in the limiting area. When a reverse pulling force is provided, the movable limiting arm rotates from the limiting area to the reverse pulling force area to push the first contact switch and the second contact switch to close, thereby limiting the operation of the telescopic drive member.
[0024] Preferably, the movable limiting arm has a protrusion located in the movable groove and capable of abutting against the first contact switch to push the first contact switch.
[0025] Preferably, the basket walking reverse auxiliary structure further includes:
[0026] An elastic element is disposed in the movable groove, with one end abutting against the first contact switch and the other end abutting against the inner wall of the movable groove.
[0027] Preferably, the support frame includes:
[0028] A fixed rod, wherein the telescopic drive component and the movable limiting arm are respectively installed at both ends of the fixed rod;
[0029] A reinforcing rod is provided on the side of the fixed rod away from the telescopic drive member and the movable limiting arm.
[0030] Preferably, a triangular structure is formed between the fixing rod and the reinforcing rod.
[0031] The reverse walking auxiliary structure for the hanging basket proposed in this utility model has the following beneficial effects:
[0032] 1. The reverse auxiliary structure for the hanging basket proposed in this utility model can cause the gravity connecting beam to violently impact the front end of the limiting space under the action of inertia when the center of gravity shifts forward due to emergency braking, sudden stop due to excessive forward speed, or uneven construction materials.
[0033] The impact force acts on the movable limiting arm, forcing it to rotate and extend. The gravity connecting beam impacts the front end of the limiting space, forcing the movable limiting arm to rotate to its limit angle. The telescopic drive component stops moving. At this point, the movable limiting arm, the support frame, and the telescopic drive component form a stable triangular structure. In a critically dangerous structural state, it actively transforms into a rigid structure, providing a strong reverse tensile force to prevent further overturning.
[0034] The system does not affect the operation of the hanging basket during normal walking. Triangular support is only triggered in extreme situations where the center of gravity is severely unstable or the inertia is too great, ensuring that the smoothness and safety of the structure coexist.
[0035] In extreme conditions, it actively locks into a triangle shape, providing the strongest reverse tensile force from a structural mechanics perspective, effectively preventing overturning.
[0036] 2. The reverse auxiliary structure for the hanging basket proposed in this utility model allows the movable limiting arm to enter the reverse tension zone when in a dangerous critical state. The movable limiting arm continues to rotate under the impact force and enters the reverse tension zone.
[0037] The protrusion at the end of the limit arm pushes the first contact switch. The first contact switch rotates with the arm and physically closes (makes contact) with the second contact switch. After the contact switch is closed, the output electrical signal controls the system to execute logic, restricting or stopping the operation of the telescopic drive, which can realize stopping telescopic movement, locking action or emergency reverse pulling, so as to provide a dual protection mechanism.
[0038] When the first contact switch contacts the second contact switch, an electrical signal is triggered to limit the movement of the telescopic drive component, preventing damage caused by continuous stress on the structure or misoperation, and further preventing the hanging basket traveling structure from overturning due to excessive travel speed.

[0054] It should be understood that the specific embodiments described herein are merely illustrative of the present invention and are not intended to limit the present invention.

They are used solely for the convenience of describing this utility model and for simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model. Furthermore, the terms "first," "second," etc., are used for descriptive purposes only and should not be construed as indicating or implying relative importance.
[0056] This utility model proposes a reverse walking auxiliary structure 100 for hanging baskets, comprising:
[0057] The main body of the hanging basket 110 has a walking structure 111, and the walking structure 111 is provided with a gravity connecting beam 112;
[0058] A support frame 120 is located at the end of the main body 110 of the hanging basket that is away from the hanging basket.
[0059] The telescopic drive component 130 is fixed at one end to the support frame 120;
[0060] A movable limiting arm 140 is rotatably connected at one end to the support frame 120 and at the other end to the telescopic drive member 130 away from the support frame 120. A limiting space 140a is formed between the movable limiting arm 140, the support frame 120, and the telescopic drive member 130. The gravity connecting beam 112 is located within the limiting space 140a.
[0061] When the main body 110 of the hanging basket moves, it drives the gravity connecting beam 112 to move within the limiting space 140a to limit the movement stroke of the gravity connecting beam 112. When the center of gravity of the main body 110 of the hanging basket is unstable, the movable limiting arm 140 provides a reverse pulling force.
[0062] Please refer to Figures 1-7In this embodiment, the main body 110 of the hanging basket moves slowly on the bridge structure according to the construction rhythm. The support frame 120 set at its tail and the movable limiting structure form a preset limiting space 140a. The movement of the hanging basket drives the gravity connecting beam 112 below it to move within the limiting space 140a. At this time, the movable limiting arm 140 is in a naturally drooping or slightly extended state, the telescopic drive 130 is not under force or only provides slight support, and the overall structure is in a relaxed limiting state, allowing a certain degree of relative movement.
[0063] When emergency braking, sudden stop due to excessive forward speed, or uneven construction materials causing the center of gravity to shift forward, the gravity connecting beam 112 violently impacts the front end of the limiting space 140a under the action of inertia.
[0064] The impact force acts on the movable limiting arm 140, forcing it to rotate and unfold. The gravity connecting beam 112 impacts the front end of the limiting space 140a, forcing the movable limiting arm 140 to rotate to its limit angle. The telescopic drive component 130 stops moving. At this point, the movable limiting arm 140, the support frame 120, and the telescopic drive component 130 form a stable triangular structure. In a critically dangerous structural state, it actively transforms into a rigid structure, providing a strong reverse tensile force to prevent the structure from overturning further.
[0065] The system does not affect the operation of the hanging basket during normal walking. Triangular support is only triggered in extreme situations where the center of gravity is severely unstable or the inertia is too great, ensuring that the smoothness and safety of the structure coexist.
[0066] In extreme conditions, it actively locks into a triangle shape, providing the strongest reverse tensile force from a structural mechanics perspective, effectively preventing overturning.
[0067] It should be noted that the main body 110 of the hanging basket and the walking structure 111 are existing technologies and will not be described in detail here. The gravity connecting beam 112 is a rectangular horizontal rod.
[0068] The telescopic drive component 130 is a hydraulic cylinder, the limiting space 140a is an open space, and the gravity connecting beam 112 passes through the limiting space 140a.
[0069] Preferably, the movable limiting arm 140 includes:
[0070] The first connecting arm 141 has a first arm 1411 and a second arm 1412 rotatably connected to one end of the first arm 1411. The end of the first arm 1411 away from the second arm 1412 is rotatably connected to the support frame 120, and the end of the second arm 1412 away from the first arm 1411 is rotatably connected to the telescopic drive member 130.
[0071] Please refer to Figures 1-7In this embodiment, under normal conditions, the movable limiting arm 140 hangs down naturally or extends slightly. The first arm 1411 is rotatably connected to the support frame 120, and the second arm 1412 can rotate freely with the telescopic drive member 130, so that the entire movable limiting arm 140 is in a non-rigid state. Under this state, the gravity connecting beam 112 runs freely within the limiting space 140a, and the movable limiting arm 140 does not interfere with the normal movement of the hanging basket.
[0072] When the hanging basket experiences an inertial impact and its center of gravity becomes unstable, the gravity connecting beam 112 violently impacts the movable limiting arm 140. The impact pushes the second arm 1412 outward. At the same time, under the pulling force of the telescopic drive component 130, the second arm 1412 cannot continue to rotate or retract, ultimately forcing the first arm 1411, the second arm 1412, and the telescopic drive component 130 to stretch to their limit angle. At this point, the first arm 1411, the second arm 1412, and the drive component form an approximately folded and stretched state, and the movable limiting arm 140 becomes a rigid force-bearing structure, forming a supporting triangle.
[0073] Under normal conditions, the two-arm structure can move freely and has good adaptability. Under extreme stress conditions, the movable limiting arm 140 will form a stable stress structure due to the tension, and quickly transform from a flexible structure to a rigid structure.
[0074] Once the center of gravity exceeds the limit or an inertial impact occurs, the movable limit arm 140 immediately extends and resists the telescopic drive component 130 to form a reverse torque. This process relies purely on mechanical linkage and does not require sensor control, resulting in fast response and high reliability.
[0075] The unfolded triangular structure is extremely stable and can provide maximum reverse tensile support in the most dangerous pre-overturning critical state, effectively preventing risks such as forward imbalance, forward tilting, and overturning of the hanging basket.
[0076] It should be noted that the first arm 1411, the third arm 1421, and the fourth arm 1422 are all rod-shaped structures, while the second arm 1412 is roughly an "H"-shaped frame structure. The first arm 1411, the second arm 1412, the third arm 1421, and the fourth arm 1422 are all connected by bearings to achieve rotational connection.
[0077] Preferably, the movable limiting arm 140 further includes:
[0078] The auxiliary connecting arm 142 has a third arm 1421 and a fourth arm 1422 rotatably connected to one end of the third arm 1421. The end of the third arm 1421 away from the fourth arm 1422 is rotatably connected to the middle of the first arm 1411, and the end of the fourth arm 1422 away from the third arm 1421 is rotatably connected to the middle of the second arm 1412.
[0079] When the main body 110 of the hanging basket moves, the movable limiting arm 140 forms a quadrilateral structure. When a reverse pulling force is required, a triangular structure is formed between the movable limiting arm 140, the support frame 120 and the telescopic drive member 130.
[0080] Please refer to Figures 1-7 In this embodiment, when the basket moves smoothly, the first arm 1411, the second arm 1412, the third arm 1421 and the fourth arm 1422 form a frame similar to a rhombus or parallelogram, allowing the movable limiting arm 140 to swing or deform with a small stroke as the gravity connecting beam 112 moves, keeping the structure conforming to the movement of the basket.
[0081] When the hanging basket impacts the movable limiting arm 140 due to excessive inertia or a sudden forward shift of the center of gravity, the quadrilateral structure deforms rapidly under the impact force. The third arm 1421 and the fourth arm 1422 will come into contact with the first arm 1411 and the second arm 1412 due to the change in the force angle at the connection point. At this time, the first arm 1411 and the second arm 1412 of the first connecting arm 141 are forced to rotate and straighten. The telescopic drive component 130 generates a reverse pulling force at this time. The rigid triangular structure formed by the support frame 120, the movable limiting arm 140 and the telescopic drive component 130 can effectively resist the torque of continued overturning.
[0082] The quadrilateral structure can initially buffer some of the inertial impact. If the impact continues or the structure becomes further unstable, the triangular locking structure will be triggered for final protection, enhancing the structure's multi-level response capability during dangerous phases.
[0083] It should be further explained that a telescopic cylinder can be installed at the connection between the first arm 1411 and the second arm 1412. One end of the telescopic cylinder is fixed at the connection between the first arm 1411 and the second arm 1412, and the other end is located at the connection between the support frame 120 and the telescopic drive member 130, so that the first arm 1411, the telescopic cylinder and the support frame 120 form a triangle, and the second arm 1412, the telescopic cylinder and the telescopic drive member 130 form a triangular structure. Under inertial impact, the telescopic cylinder can further provide a reverse pulling force to further protect the entire hanging basket structure.
[0084] Telescopic cylinders are either telescopic hydraulic cylinders or pneumatic cylinders.
[0085] Preferably, the support frame 120 has a movable groove 120a, one end of the movable limiting arm 140 is received in the movable groove 120a and is rotatably connected to the support frame 120.
[0086] Please refer to Figures 1-7In this embodiment, when the main body 110 of the hanging basket moves forward normally, the gravity connecting beam 112 moves within the limiting space 140a. At this time, the movable limiting arm 140 is in the initial position within the movable groove 120a, and can rotate and swing slightly, forming a flexible limit with the walking structure 111, without interfering with the walking behavior of the hanging basket.
[0087] When the hanging basket suddenly stops or experiences an inertial impact, the gravity connecting beam 112 strikes the movable limiting arm 140, forcing the movable limiting arm 140 to rotate. One end of the arm rotates around the pivot in the movable groove 120a, rotating to its limit position within the limiting range of the groove. It then works in conjunction with the telescopic drive component 130 to gradually form a rigid support structure (i.e., a triangular reverse support shape).
[0088] The function of the movable groove 120a at this time is to limit the maximum swing range of the movable arm, prevent excessive rotation from damaging the structure, and, in conjunction with the rotating connection point, achieve a controllable rotation angle.
[0089] When the angle exceeds the allowable range, a limiting device (such as a groove wall, contact switch, etc.) is used to brake, realizing a dual protection mechanism of advance buffering and rear locking.
[0090] It should be noted that the movable groove 120a is roughly a groove, and is roughly a rectangular groove.
[0091] Preferably, the movable groove 120a is provided with a limiting area 120b and a reverse pulling area 120c;
[0092] The movable limiting arm 140 is capable of moving within the limiting region 120b or the reverse tension region 120c.
[0093] Preferably, the basket walking reverse auxiliary structure 100 further includes:
[0094] The first contact switch 150 is located in the movable groove 120a and is rotatably connected to the support frame 120.
[0095] The second contact switch 151 is located within the reverse pull region 120c;
[0096] When the device is in a limiting position, the movable limiting arm 140 rotates in the limiting region 120b. When a reverse pulling force is provided, the movable limiting arm 140 rotates from the limiting region 120b to the reverse pulling force region 120c to push the first contact switch 150 and the second contact switch 151 to close, thereby limiting the operation of the telescopic drive member 130.
[0097] Please refer to Figures 1-7In this embodiment, the limiting area 120b is the normal range of motion, allowing the movable limiting arm 140 to rotate freely without triggering the safety device.
[0098] Reverse tension zone 120c: When an inertial impact or structural instability occurs, the movable limit arm 140 rotates further to this zone, triggering the structural protection mechanism.
[0099] During the normal travel phase of the hanging basket: the movable limiting arm 140 moves within the limiting area 120b, and the movable limiting arm 140 swings at a natural angle within the limiting area 120b to adapt to the slight inertial changes of the hanging basket without triggering any contact switches. The telescopic drive component 130 is in normal operating condition, and can extend and retract. The entire structure is in a state of passive following and initial limiting, without interfering with the normal construction and advancement of the hanging basket, and only restricting the range of motion of the gravity connecting beam 112.
[0100] When in a critical state, the movable limit arm 140 enters the reverse tension region 120c. Driven by the impact force, the movable limit arm 140 continues to rotate and enters the reverse tension region 120c.
[0101] The protrusion 1413 at the end of the limit arm pushes the first contact switch 150. The first contact switch 150 rotates with the arm and physically closes (makes contact) with the second contact switch 151. After the contact switch is closed, the output electrical signal controls the system to execute logic, restricting or stopping the operation of the telescopic drive 130. This can achieve stopping telescopic movement, locking action, or emergency reverse pulling, providing a dual protection mechanism.
[0102] When the first contact switch 150 contacts the second contact switch 151, an electrical signal is triggered to limit the movement of the telescopic drive component 130, preventing the structure from being continuously subjected to force or damage caused by misoperation, and further preventing the hanging basket traveling structure 111 from overturning due to excessive traveling speed.
[0103] It should be noted that both the first contact switch 150 and the second contact switch 151 are electrical contact pieces, and the internal circuit boards are electrically connected to the first contact switch 150 and the second contact switch 151 respectively. When the first contact switch 150 is electrically connected to the second contact switch 151, electrical conduction is achieved.
[0104] Preferably, the movable limiting arm 140 is provided with a protrusion 1413, which is located in the movable groove 120a and can abut against the first contact switch 150 to push the first contact switch 150.
[0105] Please refer to Figures 1-7In this embodiment, during normal operation, the basket moves smoothly and the movable limiting arm 140 rotates slightly within the limiting area 120b of the movable groove 120a. At this time, the protrusion 1413 does not contact the actuating surface of the first contact switch 150, or the contact angle is insufficient to drive it to rotate. The first contact switch 150 remains in its original position and cannot close with the second contact switch 151. The system is in standby mode.
[0106] When an inertial impact or sudden change in center of gravity occurs, the movable limiting arm 140 rotates under the push of the gravity connecting beam 112. The protrusion 1413 on the movable limiting arm 140 contacts the edge of the first contact switch 150 in a tangential manner. Due to the eccentricity of the contact position, a driving effect similar to that of a cam on a swing arm is formed, which pushes the first contact switch 150 to rotate around its rotation axis. After the first contact switch 150 rotates to a specific angle, it contacts and closes with the fixed second contact switch 151. After the two close, an electrical signal is output. The system recognizes this as an extreme state and then triggers the control logic (such as stopping the drive, alarm, switching states, etc.), such as: the telescopic drive component 130 stops running, an alarm is issued, or the telescopic drive component 130 is activated to pull in the opposite direction, etc.
[0107] The non-concentric contact between the protrusion 1413 and the first contact switch 150 ensures that the first contact switch 150 will only be triggered when the limit arm rotates to the set limit angle. This ensures that the system only triggers a response in a truly dangerous situation, avoids false triggering, and effectively improves the intelligent response capability and structural safety of the entire hanging basket walking auxiliary structure.
[0108] It should be noted that the protrusion 1413 is roughly an arc-shaped protrusion, and protrudes outward along the outer edge of the first arm 1411 away from the end of the second arm 1412 to form the protrusion 1413.
[0109] The first contact switch 150 is roughly an "L"-shaped swing arm structure and is provided with an electrical contact piece, which can be electrically connected to the second contact switch 151.
[0110] The first contact switch 150 is rotatably connected to the support frame 120 via a bearing.
[0111] Preferably, the basket walking reverse auxiliary structure 100 further includes:
[0112] The elastic element 152 is disposed in the movable groove 120a, with one end abutting against the first contact switch 150 and the other end abutting against the inner wall of the movable groove 120a.
[0113] Please refer to Figures 1-7In this embodiment, during the normal movement of the hanging basket, the gravity connecting beam 112 swings within the limiting space 140a, and its stroke is constrained by the limiting area 120b. Since it does not exceed the set range, the movable limiting arm 140 will not rotate significantly, the protrusion 1413 will not trigger the first contact switch 150, the elastic element 152 is in a natural elastic state, and the entire system is in a standby operation state.
[0114] When the hanging basket is subjected to inertial impact or a significant shift in its forward center of gravity, the gravity connecting beam 112 swings dramatically and impacts the movable limiting arm 140, forcing it to rotate around the axis of the support frame 120. The protrusion 1413 on the movable limiting arm 140 then enters the reverse tension region 120c of the movable groove 120a and, via a cam mechanism, pushes the first contact switch 150 to rotate. During this process, the elastic element 152 is compressed or deformed as the switch rotates, storing elastic potential energy. When the first contact switch 150 rotates to a specified angle and closes with the second contact switch 151, the system outputs a control signal to limit or stop the operation of the telescopic drive element 130.
[0115] Subsequently, when the structural load stabilizes and the impact is released, the movable limit arm 140 rotates under its own gravity or drive control, the protrusion 1413 moves away from the first contact switch 150, the elastic element 152 releases its elastic force, actively pushes the first contact switch 150 back to its initial position, the contact switch is disconnected, the system is reset, and it returns to the initial standby state.
[0116] The elastic element 152 ensures that the first contact switch 150 can quickly return to its original position after being triggered, ensuring that the system can be used multiple times during construction without manual intervention.
[0117] The elastic element 152 provides a continuous thrust, keeping the first contact switch 150 at a preset initial angle, thereby improving the accuracy of the trigger point position and the repeatability of the action.
[0118] During the rotation of the switch, the elastic element 152 absorbs part of the impact force, avoiding direct impact between rigid components and extending the service life of the system.
[0119] It should be noted that the elastic element 152 is a spring.
[0120] Preferably, the support frame 120 includes:
[0121] The fixed rod 121, the telescopic drive component 130 and the movable limiting arm 140 are respectively installed at both ends of the fixed rod 121;
[0122] A reinforcing rod 122 is provided on the side of the fixed rod 121 away from the telescopic drive member 130 and the movable limiting arm 140.
[0123] Please refer to Figures 1-7 In this embodiment, the fixed rod 121 is the main load-bearing component of the support frame 120. The fixed rod 121 is roughly a rectangular upright, with the telescopic drive component 130 and the movable limiting arm 140 fixedly installed at both ends to provide a stable installation foundation.
[0124] The reinforcing rod 122 is set on the other side of the fixed rod 121, thus forming an oblique support connection, thereby forming a triangular reinforcement structure with the fixed rod 121 to enhance the overall rigidity and load-bearing capacity.
[0125] This invention solves the problems of deformation, swaying, and structural instability faced by the movable limit system under inertial impact and structural displacement during the operation of the hanging basket, thereby improving the overall stability and safety of the system.
[0126] When the hanging basket is in normal walking state, the gravity connecting beam 112 swings within the limiting space 140a, the movable limiting arm 140 remains rotatably connected, and the entire support frame 120 provides a reliable installation foundation for it. Once extreme states such as inertial impact or instability of the center of gravity occur, the movable limiting arm 140 is impacted by the gravity connecting beam 112 and forced to rotate. At the same time, the telescopic drive component 130 is fixed and forms a rigid reverse support.
[0127] At this time, the movable limiting arm 140 and the telescopic drive component 130 installed at both ends of the fixed rod 121 will be subjected to a large reverse tensile force or structural impact. If it is supported by only a slender fixed rod 121, it may bend, swing or become unstable. The addition of the reinforcing rod 122 makes the fixed rod 121 and it form a triangular stable structure, which effectively resists bending moment and impact force, and keeps the shape of the support frame 120 stable and the force balanced throughout the deformation process.
[0128] Through the connection between the fixed rod 121 and the reinforcing rod 122, the support frame 120 forms a triangle with spatial stability, which can effectively resist the combined forces in the horizontal, vertical and inclined directions.
[0129] The reinforcing rod 122 serves as an auxiliary support to alleviate the problem of stress concentration on the fixed rod 121 and prevent bending, breakage, or structural swaying.
[0130] Preferably, the fixing rod 121 and the reinforcing rod 122 form a triangular structure.
[0131] Please refer to Figures 1-7 In this embodiment, a triangular structure is formed between the fixing rod 121 and the reinforcing rod 122, which makes it more stable, provides better tension on the hanging basket, and prevents the hanging basket from tipping over due to unstable center of gravity or other reasons.
[0132] The above are merely preferred embodiments of this utility model and do not limit the patent scope of this utility model. Any equivalent structural transformations made based on the description and drawings of this utility model, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of this utility model.
