Description

Technical Field

[0001] This utility model relates to the field of transfer vehicles, specifically a transfer vehicle storage structure. Background Technology

[0002] The current frame structure of a transfer vehicle mainly includes a base, two support legs connected to the outside of the base, support columns fixed to the base, and handrails connected to the support columns. However, the handrails and moving legs in current transfer vehicles are generally disassembled and stored, requiring reinstallation before use. The installation process is complicated, time-consuming, and labor-intensive, resulting in low efficiency. Moreover, after disassembly and reassembly, the components are scattered and difficult to store.

[0003] As shown in Chinese patent document, application number 202320096951.8, a folding structure for a transfer cart is described. Although the folding support (i.e., the moving leg) can be folded for storage, it can only be folded upwards. Therefore, after folding, the transfer cart only has two support points at the front end (two first pulleys in contact with the ground). This means that the transfer cart can only maintain its upright position when it is folded and is prone to tipping over, which increases the space occupied during storage. Therefore, the applicant has improved and perfected the transfer cart to solve the above problems and provide it for consumers to choose and use. Utility Model Content

[0023] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0024] See Figures 1 to 4 As shown, a transfer cart storage structure includes a frame 1, which includes a base 2, two support legs 3, a lifting column 4, and a support handle 5. Each of the two support legs 3 includes a rear support section 31 and a front support section 32. The rear support section 31 is connected to the outside of the base 2, and the front support section 32 is rotatably connected to the front end of the rear support section 31 and can be folded inward to the front of the base 2. Casters 6 are connected to the outer ends of both the rear support section 31 and the front support section 32. The lifting column 4 is connected to the upper side of the base 2, and the support handle 5 is connected to the movable end of the lifting column 4 and can reciprocate between the unfolded position and the stored position.

[0025] The support legs 3 and support handles 5 in this transfer cart can be folded for storage (e.g., Figure 2 As shown), the volume is further reduced when stored, and the components are no longer scattered when stored. It can also quickly switch between the storage state and the use state, eliminating the need to install the support legs 3 and / or support armrests 5 every time it is reused, thus improving the efficiency of use and making the operation simple and convenient.

[0026] Another point is that after the transfer cart is folded, the four casters 6 still remain in contact with the ground, maintaining relatively parallel support points, so that the transfer cart can still stand upright when folded, reducing the space occupied when storing.

[0027] It also includes a single-board seat cushion 7, and the left and right sides of the seat cushion 7 are provided with hanging connectors 8 that are connected to the support armrest 5. The seat cushion 7 is connected to the bottom of the support armrest 5 through the hanging connectors 8.

[0028] This structure supports the armrest 5 and seat 7 via the lifting column 4, eliminating the need for an additional mounting frame structure for the frame 1, reducing the complexity of the frame 1's construction, and making the frame 1 structure simpler. In addition, the height of the armrest and seat 6 can be adjusted simultaneously and freely by lifting the lifting column 4, without having to separate the two parts for operation, making it more convenient to use.

[0029] The front side of the movable end of the lifting column 4 is fixedly connected to a handrail support structure 9. When the handrail 5 is in the unfolded position, it abuts against the upper side of the handrail support structure 9, so that the handrail 5 extends laterally and is placed in front of the lifting column 4. The handrail support structure 9 can limit the position of the handrail 5 to flip forward, providing support for the handrail 5 while realizing the limiting function.

[0030] A single lifting column 4 is connected to the upper side of the base 2 along the central axis. The support handrail 5 has a "U" shaped structure, including a middle section 51 and two handrails 52. The middle section 51 is rotatably connected to the rear side of the movable end of the lifting column 4 through a tube clamp 53. The two handrails 52 are symmetrically connected to the two ends of the middle section 51.

[0031] This structure relies on a single lifting column 4 in conjunction with a "U"-shaped support armrest 5. When the user sits, the lifting column 4 is positioned between the two legs, while the outer side of the legs has more lateral movement space, which can improve the user's riding comfort and reduce the restriction on the legs.

[0032] The handrail support structure 9 includes a support horizontal tube 91, with two ends of the support horizontal tube 91 provided with upward-opening tube clamps 92. The middle of the support horizontal tube 91 is fixedly connected to the lifting column 4 through a connecting block 93. The two handrails 52 of the support handrail 5 are positioned and abutted (which may be a clearance fit or an elastic interference fit) within the tube clamps 92.

[0033] It can fix the handrail 5 on the handrail support structure 9, and can position the handrail 52 so that it will not sway left and right, maintain the stability of the handrail 5, and is not easily deformed when bearing weight.

[0034] The rear support section 31 is provided with a pipe connector 311 at its front end, and the front support section 32 is provided with a pipe fork 321 at its rear end. The pipe fork 321 is rotatably connected to the pipe connector 311 through a hinge shaft 33, and the two front support sections 32 are folded in front of the base 2 respectively.

[0035] In this embodiment, the front end of the rear support section 31 is positioned relative to the base, and the two front support sections 32 have pipe connectors 311 at different positions with different lengths. After the two front support sections 32 are folded inward by 90°, they can be folded back and forth on the front side of the base 2. After folding, they remain on the same horizontal plane and do not interfere with each other, keeping the folded state compact and saving space.

[0036] In addition, the rear support section 31 includes an outer tube and an inner tube. The outer tube is sleeved outside the inner tube, and at least one end of the inner tube extends out of the outer tube, with the extended portion forming a pipe connector 311. Therefore, when the front support section 32 is unfolded relative to the rear support section 31, the front support section 32 can maintain the same pipe diameter as the outer tube, making the support leg 3 more consistent.

[0037] The upper part of the pipe fork 321 is provided with a movable locking structure. When the front support section 32 is unfolded relative to the rear support section 31, the movable locking structure locks with the pipe connector 311. The movable locking structure keeps the front support section 32 in a relative position with the rear support section 31 when the front support section 32 is unfolded.

[0038] Specifically, the active locking structure includes a hexagonal head 34, with an external threaded sleeve 341 at the bottom of the hexagonal head 34 and a lower clutch part 342 at the top of the hexagonal head 34. The upper part of the pipe fork 321 has a threaded hole 322 that connects to the external threaded sleeve 341.

[0039] It also includes a manual knob 35, the bottom of which is provided with a pin 351 that passes through the hexagonal head 34 and the external threaded sleeve 341, and an upper clutch part 352 that cooperates with the lower clutch part 342. The pipe connector 311 has a pin hole that cooperates with the pin 351. The pin hole includes a first pin hole 312 and a second pin hole 313 corresponding to the unfolded position and the folded position of the front support section 32.

[0040] During installation, the hexagonal head 34 is screwed into the threaded hole 322 through the external threaded sleeve 341, thereby fixing it to the pipe fork 321. The hexagonal head 34 can be screwed in using a tool for better tightening. Alternatively, after the manual knob 35 is coupled with the lower clutch 342 through the upper clutch 352, the manual knob 35 can be used to drive the hexagonal head 34 to rotate synchronously, so that the external threaded sleeve 341 can be screwed into the threaded hole 322.

[0041] When the current support section 32 is unfolded, the user can use the manual knob 35 to pull out the pin 351. After the pin 351 is aligned with the first pin hole 312, the user can then control the manual knob 35 to insert the pin 351 into the first pin hole 312 to complete the unfolding and locking. Conversely, when the current support section 32 is folded, the user can use the manual knob 35 to pull out the pin 351 from the first pin hole 312 to unlock it. Then, the user can fold the front support section 32 inward until the pin 351 is aligned with the second pin hole 313. Finally, the user can control the manual knob 35 to insert the pin 351 into the second pin hole 313 to complete the folding and locking.

[0042] The hanging connector 8 includes several flexible strips 81 arranged at intervals. The lower end of the flexible strip 81 is fixedly connected to the seat cushion 7, and the upper end of the flexible strip 81 is connected to the support armrest 5. The seat cushion 7 is suspended below the support armrest 5 by the flexible strip 81.

[0043] When the support armrest 5 can be folded, the seat cushion 7 is connected to the support armrest 5 by a flexible strap 81, which can save space when folded. Moreover, the flexible connection between the seat cushion 7 and the support armrest 5 can also play a certain role in shock absorption and cushioning during the use of the transfer vehicle, which can improve the comfort of the user.

[0044] The supporting horizontal tube 91 is also connected to two handles 94 arranged on the left and right; each handle 94 is fitted with an anti-slip grip sleeve 941; the two handles 94 are mainly for the convenience of the user. When the user needs to stand up or lift his / her buttocks, he / she can hold the handles 94 to help the user's arms to support the body; while the anti-slip grip sleeve 941 has the effect of preventing the hand from slipping.
