Description

Technical Field

[0001] This utility model relates to the field of wheel accessories technology, specifically a lightweight folding transport wheel. Background Technology

[0002] In logistics transportation, warehousing management, and various handling scenarios, lightweight folding handling wheels are components located at the bottom of the vehicle body. They are used to move and use the handling equipment, making the handling process less strenuous.

[0003] Traditional methods of connecting transport wheels to the mounting plate often involve welding or a single bolt. While welding provides a strong connection, damage to the wheel necessitates replacing the entire transport equipment or performing complex cutting and welding repairs, resulting in high maintenance costs and significant time consumption. Single bolt fixation, while offering strong load-bearing capacity during transport, involves numerous parts, complex assembly and disassembly procedures requiring tools, and is time-consuming and labor-intensive. Furthermore, it is inconvenient for subsequent maintenance and lacks lateral impact resistance, making it prone to wheel sway under heavy loads. To address these shortcomings, this invention provides a lightweight folding transport wheel to solve the aforementioned problems. Utility Model Content

[0028] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions in the embodiments of this utility model are described clearly and completely. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0029] To better understand the above technical solutions, the following will provide a detailed explanation of the technical solutions in conjunction with the accompanying drawings and specific implementation methods.

[0030] This utility model discloses a lightweight folding transport wheel, according to the attached... Figure 1-5 As shown, the device includes a fixed plate 1, a bearing seat 2 at the bottom of the fixed plate 1, and a wheel body 3 rotatably connected to the bottom of the bearing seat 2. An installation mechanism is provided between the fixed plate 1 and the bearing seat 2. The installation mechanism includes a sleeve 4, a snap-fit ​​component 5, and a locking unit 6. The sleeve 4 is fixedly connected to the fixed plate 1. The snap-fit ​​component 5 is fixedly connected to the bearing seat 2 and movably snap-fitted inside the sleeve 4. The cross-section of the snap-fit ​​component 5 is T-shaped. The locking unit 6 is provided on the sleeve 4 and is used to lock the snap-fit ​​component 5.

[0031] According to the appendix Figure 2 , 4 As shown, furthermore, the sleeve 4 has a slot 41 inside that corresponds to the snap-fit ​​component 5. The slot 41 is T-shaped. Through the cooperation of the T-shaped slot 41 and the T-shaped snap-fit ​​component 5, the shaft seat 2 and the fixing plate 1 are initially positioned and snapped together, preventing relative displacement between the two in the horizontal direction.

[0032] According to the appendix Figure 3-4As shown, the snap-fit ​​component 5 has several sets of locking holes 51 on its side. The locking unit 6 includes a guide rail frame 61, a control block 62, and several sets of locking rods 63. The guide rail frame 61 is fixedly connected to the sleeve 4; the control block 62 is slidably connected to the guide rail frame 61; and the several sets of locking rods 63 are all fixedly connected to the control block 62 and are respectively movably snapped into the corresponding locking holes 51. By moving the locking rods 63 driven by the control block 62, the locking rods 63 are inserted into the locking holes 51 of the snap-fit ​​component 5, thereby locking the snap-fit ​​component 5 vertically and preventing the shaft seat 2 from separating from the fixing plate 1.

[0033] According to the appendix Figure 4 As shown, a lead screw 64 is threaded onto the guide rail frame 61, and the lead screw 64 is rotatably connected to the control block 62. By rotating the lead screw 64, the control block 62 is moved along the guide rail frame 61 using threaded transmission, thereby achieving precise positioning and locking of the locking rod 63.

[0034] According to the appendix Figure 4 As shown, a rotating handle 641 is further fixedly connected to the lead screw 64. The rotating handle 641 provides an operating fulcrum, facilitating manual rotation of the lead screw 64 and improving the convenience of the locking operation.

[0035] According to the appendix Figure 2 , 3 As shown in Figure 4, furthermore, a reinforcing rod 7 is fixedly connected to the guide rail frame 61, and a reinforcing tube 71 that engages with the reinforcing rod 7 is fixedly connected to the bearing seat 2. The engagement between the reinforcing rod 7 and the reinforcing tube 71 enhances the connection stability between the bearing seat 2 and the fixing plate 1, preventing loosening during transportation.

[0036] According to the appendix Figure 1 As shown, the fixing plate 1 is provided with several sets of fixing holes 11. The fixing plate 1 can be installed on the handling equipment using fasteners such as bolts through the fixing holes 11, so as to realize the quick installation and removal of the wheel.

[0037] The working principle of this lightweight folding transport wheel is as follows:

[0038] Initial positioning is achieved through the cooperation of T-shaped snap-fit ​​5 and T-shaped slot 41. Then, vertical locking is achieved by inserting the locking rod 63 of locking unit 6 into locking hole 51. Finally, the connection stability is enhanced by the snap-fit ​​of reinforcing rod 7 and reinforcing tube 71, forming a multi-level fixing structure. When the wheel body 3 malfunctions, jams, or is damaged, it is easy to quickly disassemble and replace it from below the fixing plate 1 for maintenance.

[0039] The steps for using these lightweight folding transport wheels are as follows:

[0040] Align the snap-fit ​​5 of the bearing seat 2 with the snap-fit ​​groove 41 of the sleeve 4 and insert it;

[0041] Rotating the handle 641 drives the lead screw 64 to rotate, causing the control block 62 to move along the guide rail frame 61;

[0042] Observe that the locking rod 63 is fully inserted into the locking hole 51 of the snap-fit ​​component 5;

[0043] Check whether the reinforcing rod 7 is fully engaged with the reinforcing tube 71;

[0044] The fixing plate 1 is installed on the handling equipment through the fixing hole 11.

[0045] The benefits of this lightweight folding transport wheel are as follows:

[0046] The T-shaped snap-fit ​​structure enables rapid positioning and installation, ensuring the connection strength and stability at the joints while improving assembly efficiency.

[0047] A multi-stage locking mechanism ensures connection stability and prevents loosening during handling;

[0048] The modular design facilitates disassembly and maintenance, allowing for the individual replacement of damaged parts.
