[0019] (III) Beneficial Effects

[0020] Compared with the prior art, this utility model provides an overall multi-directional folding and fixing structure, which has the following beneficial effects:

[0021] This invention utilizes a folding mechanism to fold and retract the front and rear sections of the frame assembly. Simultaneously, the front tube folding mechanism independently controls the folding of the front tube relative to the front section of the frame assembly. The locking body and the compression spring work together to ensure stability in the unfolded state. After folding, the column hook is guided by an inclined surface to automatically trigger the folding buckle slider to engage with the slot, completing the first layer of anti-pull-out locking. Combined with the sliding engagement of the front tube hook and the top clamping shaft, a second layer of anti-loosening locking is formed, ensuring that the folding state in both dimensions is simultaneously stable. Only three consecutive actions—pressing to unlock, flipping the frame, and sliding the hook—are required to complete the bidirectional folding and unlocking with one hand, significantly improving folding efficiency, storage compactness, and operational convenience.

[0033] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model. Example

[0034] like Figure 1-10As shown, an embodiment of the present invention proposes an overall multi-directional folding and fixing structure, including a rear section 1 of the frame assembly, a front section 2 of the frame assembly, and a front tube assembly 3. One end of the front section 2 of the frame assembly is movably mounted on the rear section 1 of the frame assembly via a folding member 4, and the other end of the front section 2 of the frame assembly is movably connected to the front tube assembly 3 via a front tube folding assembly 6. A folding handle assembly 41 is provided on the folding member 4.

[0035] like Figure 4-5 As shown, in some embodiments, the folding member 4 includes a first connecting seat 42 and a second connecting seat 43 that are hinged to each other. The first connecting seat 42 is fixed to one end of the rear section 1 of the frame assembly, and the second connecting seat 43 is fixed to one end of the front section 2 of the frame assembly. The folding handle assembly 41 is movably disposed at the end of the first connecting seat 42 away from the hinge.

[0036] Connector 1 42 and Connector 2 43 are respectively fixed on the rear section 1 and the front section 2 of the frame assembly. The hinged layout of Connector 1 42 and Connector 2 43 forms a rotation fulcrum, and Connector 1 42 and Connector 2 43 are thickened to improve the overall structural strength of the product.

[0037] like Figure 4 As shown, in some embodiments, the folding handle assembly 41 includes a locking handle 411, and a locking body 412 is rotatably disposed inside the locking handle 411. One end of the locking body 412 is hook-shaped and engages with the locking hole 21 on one side of the front section 2 of the frame assembly, and the other end is provided with a compression spring 413.

[0038] The spring 413 continuously abuts against the locking body 412, so that the hook-shaped end of the locking body 412 is stably engaged with the lock hole 21. When unlocking, press the locking handle 411 to compress the spring 413, so that the hook-shaped end is disengaged from the lock hole 21, and the front section 2 of the frame assembly can be folded.

[0039] like Figure 4 As shown, in some embodiments, a folding locking assembly 5 is also included. The folding locking assembly 5 includes a folding buckle slider 1 51 and a folding buckle slider 2 52 located outside and inside the front section 2 of the frame assembly, respectively. A folding buckle handle seat 53 is provided on one side of the folding buckle slider 2 52. The three are coaxially fixed by screws 54.

[0040] The folding buckle slider 1 51, folding buckle slider 2 52 and folding buckle handle base 53 are fixed by screws 54 to achieve synchronous movement, and the number of screws 54 is not less than two.

[0041] like Figure 4 As shown, in some embodiments, a waist-shaped hole 22 is provided on one side of the front section 2 of the frame assembly, which is fitted with a screw 54, and a spring 23 located on one side of the screw 54 is provided inside the waist-shaped hole 22.

[0042] The number of waist-shaped holes 22 is the same as the number of screws 54 and they correspond one-to-one. The spring 23 continuously abuts against the screws 54 through its elastic force. The screws 54 drive the folding buckle slider 52 and the folding buckle handle seat 53 to continuously block one side of the connecting hole 24. When the column hook 11 passes through the connecting hole 24, it is locked into the slot on it, thus limiting the column hook 11.

[0043] like Figure 5 As shown, in some embodiments, the end of the folding buckle handle seat 53 away from the folding buckle slider 52 extends to the outside of the front section 2 of the frame assembly and is bent into a hook shape.

[0044] The folding buckle handle 53 extends to the outside of the front section 2 of the frame assembly, which facilitates user operation. The hook-shaped design of one end of the folding buckle handle 53 makes it easy for the user to pull the folding buckle handle 53.

[0045] like Figure 4 As shown, in some embodiments, a connecting hole 24 located on one side of the waist-shaped hole 22 is provided on one side of the front section 2 of the frame assembly, and one end of the folding buckle slider 52 and the folding buckle handle seat 53 extends to one side of the connecting hole 24.

[0046] After the connecting hole 24 flips with the front section 2 of the frame assembly and comes into contact with the rear section 1 of the frame assembly, the connecting hole 24 and the column hook 11 are coaxially opposite each other.

[0047] like Figure 7 As shown, in some embodiments, a column hook 11 matching the connection hole 24 is provided on one side of the rear section 1 of the frame assembly.

[0048] The end of the column hook 11 away from the rear section 1 of the frame assembly is inclined, and the column hook 11 is also provided with a slot, which is engaged with one end of the folding buckle slider 52 and the folding buckle handle seat 53 to achieve the limit.

[0049] like Figure 1 As shown, in some embodiments, the front tube folding assembly 6 is rotatably disposed inside one end of the front section 2 of the frame assembly, the front tube assembly 3 is rotatably disposed on one end of the front tube folding assembly 6, and the front tube assembly 3 is also movably fitted with a front tube hook 31.

[0050] A button is provided on one side of the front tube folding assembly 6, and a limit post is provided on the side of the button. At least two sets of holes are provided at one end of the front tube assembly 3 to match the limit post, which correspond to the opening angle and folding angle of the front tube assembly 3 respectively. By pressing the button to drive the limit post out of the hole, the front tube assembly 3 can be rotated. After adjustment, the limit post is inserted into the hole to lock it. The front tube hook 31 is set up to cooperate with the top clamping shaft 44 to further ensure the stability of the front tube assembly 3 in the folded state.

[0051] like Figure 8 As shown, in some embodiments, the end of the second connecting seat 43 away from the hinge is provided with a tightening shaft 44 that matches the front tube hook 31, and the opposite surfaces of the second connecting seat 43 and the first connecting seat 42 are respectively provided with matching positioning pins 45 and positioning grooves 46.

[0052] After the second connecting seat 43 and the first connecting seat 42 are attached together, the positioning post 45 extends into the interior of the positioning groove 46, which further ensures the relative stability of the first connecting seat 42 and the second connecting seat 43. They can only rotate around the hinge point and will not shift or wobble back and forth.

[0053] When the overall multi-directional folding and fixing structure needs to be folded, open the front tube folding assembly 6 and rotate the front tube assembly 3 backward to fold it. Place it against one side of the front section 2 of the frame assembly and press one end of the locking body 412 to compress the spring 413, so that the hook-shaped end of the locking body 412 disengages from the locking hole 21.

[0054] Then rotate the front section 2 of the frame assembly 180 degrees relative to the rear section 1 of the frame assembly, so that it comes close to the rear section 1 of the frame assembly, while simultaneously making the connecting seat 42 and the connecting seat 43 unfold 180 degrees.

[0055] After the front section 2 and the rear section 1 of the frame assembly are brought together, one end of the column hook 11 is inserted into the interior of the connecting hole 24. During this process, the inclined surface of one end of the column hook 11 abuts against one end of the folding buckle slider 2 52 and the folding buckle handle seat 53, so that the folding buckle slider 2 52, the folding buckle slider 1 51 and the folding buckle handle seat 53 are linked together and the screw 54 compresses the spring 23 to avoid them. When the slot on the column hook 11 is opposite to the folding buckle slider 2 52 and the folding buckle handle seat 53, the folding buckle slider 2 52 and the folding buckle handle seat 53 spring back and lock into the slot on the column hook 11, thereby locking the front section 2 and the rear section 1 of the frame assembly in the folded state and preventing them from opening.

[0056] Then the front tube hook 31 is slid down and locked onto the top clamping shaft 44 to lock the front tube assembly 3 and the front section 2 of the frame assembly in the folded state, preventing them from opening.

[0057] When folded and then opened again, slide the front tube hook 31 up to disengage from the top clamping shaft 44, open the front tube folding assembly 6, rotate the front tube assembly 3 to open, and then lock it through the front tube folding assembly 6.

[0058] Next, lift the folding buckle handle seat 53. The folding buckle handle seat 53 will cause the folding buckle slider 52 to disengage from the locking limit of the column hook 11. Then, rotate the front section 2 of the frame assembly to open it. After opening, insert the buckle body 412 into the lock hole 21.

[0059] In summary, this overall multi-directional folding and fixing structure achieves the folding and closing of the front section 2 and rear section 1 of the frame assembly through the folding component 4. At the same time, the front tube folding assembly 6 independently controls the folding of the front tube assembly 3 relative to the front section 2 of the frame assembly. The locking body 412 and the compression spring 413 work together to ensure the stability of the unfolded state. After folding, the column hook 11 is automatically triggered by the inclined surface to trigger the folding buckle slider to engage with the slot, completing the first layer of anti-pull-out locking. Combined with the sliding engagement of the front tube hook 31 and the top clamping shaft 44, a second layer of anti-loosening locking is formed, so that the folding state in both dimensions is stable simultaneously. Only three consecutive actions of pressing to unlock, flipping the frame, and sliding the hook are required to complete the bidirectional folding and unlocking with one hand, which greatly improves folding efficiency, storage compactness, and operation convenience.

[0060] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
