[0002] In modern industrial and commercial environments, mobile structures are widely used in various equipment and devices, especially in display racks, logistics trolleys, furniture, and medical equipment, where they greatly enhance the flexibility and adaptability of the equipment. However, with the continuous expansion of application scenarios and the increasing demands of users, the design of traditional mobile structures has begun to show its limitations.

[0003] These limitations are mainly reflected in the fixed nature of the structure, that is, they are usually fixedly installed at the bottom of the device and lack the ability to be dynamically adjusted according to actual usage needs. They can provide convenience when the device needs to be moved, but they are not flexible enough when it is not necessary to move the device or when space saving and stability need to be improved. Utility Model Content

The retractable moving structure drives the transmission rod to rotate through the drive rod, thereby realizing the lifting and lowering control of the moving structure. At the same time, the limiting structure can fix and limit the moving structure after it is lowered, ensuring the stability of the equipment in the moving state.

[0005] The technical solution adopted by this utility model to solve its technical problem is: A retractable movable structure includes: a transmission rod, at least two movable structures, a drive rod, and a limiting structure; the transmission rod is vertically hinged to the movable structures, and the drive rod and the limiting structure are both fixedly installed on the transmission rod.

[0006] Optionally, the movable structure includes a connecting shaft, a support frame, and casters. The connecting shaft is hinged to the transmission rod, the support frame is fixedly connected to the lower part of the connecting shaft, and the casters are installed inside the support frame.

[0007] Optionally, the limiting structure includes an eccentric workpiece, which is fixedly connected to the transmission rod; a first limiting part is formed between the eccentric workpiece and the mounting equipment base.

[0008] Optionally, the limiting structure further includes a limiting rod, and a second limiting part is formed between the limiting rod and the base of the installation equipment.

[0009] Optionally, the telescopic movable structure further includes a fixing member, and the connecting shaft is provided with a mounting hole for the transmission rod to be inserted.

[0010] Optionally, the eccentric workpiece is an eccentric cam or a U-shaped part.

[0011] Optionally, the eccentric workpiece is an eccentric column.

[0012] Optionally, the drive rod and the limiting rod are fixedly connected to form an "L-shaped" structure.

[0013] The beneficial effects of this utility model are: This utility model's retractable movable structure uses a drive rod to drive a transmission rod to rotate, thereby achieving lifting and lowering control of the movable structure. Simultaneously, a limiting structure can fix the movable structure after it descends, ensuring the stability of the equipment during movement. Furthermore, this utility model features a simple structure, low cost, and convenient operation. The entire retractable operation process requires no bending over and can be easily completed with one foot. When moving the equipment, simply step on the drive rod lightly, and the movable structure will automatically lower, allowing you to push the equipment to any location.

Detailed Implementation

[0016] The present invention will now be described in further detail. The embodiments described below are exemplary and intended to explain the present invention, and should not be construed as limiting the present invention. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without inventive effort are within the scope of protection of the present invention.

[0017] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings.

[0018] Traditional mobile structures in existing technologies are usually fixedly installed at the bottom of the device, lacking the ability to be dynamically adjusted according to actual usage needs. That is, they can provide convenience when the device needs to be moved, but they are not flexible enough when movement is not required or when space saving and stability need to be improved.

[0019] In addition, while existing scalable and mobile structures on the market offer some solutions, they still have some shortcomings, such as complex operation, insufficient structural stability, and relatively high cost. These problems not only affect the user experience but also limit the application potential of these structures in a wider range of fields.

[0020] To address the issues of poor flexibility, complex structure, and high cost associated with traditional mobile structures in the prior art, this utility model provides a retractable mobile structure, see [link to relevant documentation]. Figures 1-13 As shown, the retractable movable structure includes: a transmission rod 1, at least two movable structures 2, a drive rod 3, and a limiting structure 4; wherein, the transmission rod 1 is vertically hinged to the movable structure 2, and the drive rod 3 and the limiting structure 4 are both fixedly installed on the transmission rod 1.

[0021] The retractable movable structure of this utility model drives the transmission rod 1 to rotate via the drive rod 3, thereby realizing the lifting and lowering control of the movable structure 2. At the same time, the limiting structure 4 can fix the movable structure 2 after it descends, ensuring the stability of the equipment in the moving state. In addition, this utility model has a simple structure, low cost, and convenient operation. The entire telescopic operation does not require the user to bend over and can be easily completed with one foot. When we want to move the equipment, we only need to lightly step on the drive rod 3, and the movable structure 2 will automatically fall down. Then we can push the equipment to any location. When we reach the destination, we only need to lightly hook the drive rod 3 with our toes, and the movable structure 2 will automatically lift up, so that the equipment lands stably and is fixed in place, realizing flexible switching between the fixed and moving states.

[0022] The present invention preferably has two movable structures 2, which are respectively located at both ends of the transmission rod 1. This not only simplifies the structure and saves costs, but also enhances the overall balance and durability of the structure, achieving a balance between structural stability and cost-effectiveness.

[0023] The preferred movable structure 2 of this utility model includes a connecting shaft 21, a support frame 22 and casters 23. The connecting shaft 21 is hinged to the transmission rod 1, the support frame 22 is fixedly connected to the lower part of the connecting shaft 21, and the casters 23 are installed inside the support frame 22.

[0024] The preferred limiting structure 4 of this utility model includes an eccentric workpiece 41, which is fixedly connected to the transmission rod 1. The axis of the eccentric workpiece 41 and the axis of the transmission rod 1 have an eccentric distance. Furthermore, a first limiting part 411 is formed between the eccentric workpiece 41 and the transmission rod 1 and the mounting base of the equipment. When the driving rod 3 drives the transmission rod 1 and the eccentric workpiece 41 to rotate to a certain position, the eccentric workpiece 41 can abut against the mounting base of the equipment, thereby forming the first limiting part 411, which can effectively achieve stable limiting after the moving structure 2 descends.

[0025] The preferred limiting structure 4 of this utility model also includes a limiting rod 42, and a second limiting part 421 is formed between the limiting rod 42 and the base of the installation equipment, so that the second limiting part 421 between the limiting rod 42 and the equipment base provides an additional fixing point, further ensuring that the moving structure 2 can land and move stably after descent.

[0026] The preferred telescopic movable structure of this utility model also includes a fixing member 5, and the connecting shaft 21 is provided with a mounting hole 211 for inserting the transmission rod 1. After the transmission rod 1 is inserted into the mounting hole 211, one end of the transmission rod 1 is fixed by the fixing member 5 to prevent it from sliding out of the mounting hole 211.

[0027] In this invention, the design of the eccentric workpiece 41 offers high flexibility. Specifically, the eccentric workpiece 41 can be configured as an eccentric cam or a U-shaped component, providing operators with diverse options to meet different practical application needs. However, considering both cost control and reduced structural complexity, this invention further prefers to use an eccentric column as the eccentric workpiece 41, which not only reduces manufacturing difficulty but also ensures the stability of its performance, thereby achieving effective cost control while guaranteeing performance.

[0028] The preferred embodiment of this invention is that the drive rod 3 and the limiting rod 42 are fixedly connected to form an "L-shaped" structure, which helps to provide clear guidance during operation and ensures precise control of the moving structure 2.

[0029] Based on the above-described preferred embodiments of this utility model, and through the foregoing description, those skilled in the art can make various changes and modifications without departing from the technical concept of this utility model. The technical scope of this utility model is not limited to the contents of the specification, but must be determined according to the scope of the claims.
