Detailed Implementation

[0026] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the following description, in conjunction with specific illustrations, further elaborates on this utility model.

[0027] Combination Figures 1 to 6 As shown, this utility model discloses a lockable folding device for folding vehicles, including a folding device. The folding device includes a first folding seat 1 and a second folding seat 2, which are hinged together. The first folding seat 1 is provided with a hinge seat 12, and the second folding seat 2 is provided with a hinge lug seat 22. The hinge lug seat 22 is used to cooperate with the hinge seat 12. The first folding seat 1 and the second folding seat 2 can be folded, flipped, or folded together through the hinge seat 12 and the hinge lug seat 22.

[0028] In conjunction with the above, the folding device also includes a locking mechanism 3, which includes a locking pin 31, a locking seat 32, and an opening / closing member 33. A locking pin seat 11 is provided within the first folding seat 1, and the locking pin seat 11 is mounted on the hinge seat 12. A locking pin hole 111 is provided within the locking pin seat 11, and the locking pin 31 corresponds to and engages with the locking pin hole 111. The locking pin 31 is typically a threaded rod, and the locking pin hole 111 is a threaded hole, allowing for a threaded fit and enabling the locking pin 31 to move into the locking pin hole 111. When the first folding seat 1 and the second folding seat 2 are combined, they form a locking cavity 4. The opening / closing member 33 drives the locking pin 31 and causes the locking seat 32 to engage with the locking cavity 4. The second folding seat 2 is provided with a locking pin cavity 21, which is used to accommodate a portion of the locking pin 31.

[0029] In combination with the above, the locking cavity 4 includes a first locking cavity 41 and a second locking cavity 42. The first locking cavity 41 is located inside the first folding seat 1, and the second locking cavity 42 is located inside the second folding seat 2. The first locking cavity 41 includes a first limiting part 411, and the second locking cavity 42 includes a second limiting part 421. The first limiting part 411 and the second limiting part 421 form a protrusion in the direction of the locking seat 32. The locking seat 32 includes a limiting cavity 321, and the limiting cavity 321 forms a recess in the direction of the opening and closing member 33. The shape of the limiting cavity 321 matches that of the first limiting part 411 and the second limiting part 421. When the locking seat 32 and the locking cavity 4 complete the locking engagement, the first limiting part 411 and the second limiting part 421 are engaged in the limiting cavity 321 and abut against the limiting cavity 321.

[0030] In combination with the above, the opening and closing component 33 includes a rotating handle 331 and a drive seat 332. The drive seat 332 is fixedly engaged with one end of the locking pin 31. By rotating the rotating handle 331, the drive seat 332 and the locking pin 31 can rotate together. The locking pin 31 passes through the locking pin cavity in the locking seat 32.

[0031] Based on the above installation structure, the working process and principle of this utility model are as follows:

[0032] In one preferred embodiment, the locking pin 31 and the locking pin hole 111 are provided with mating threads. After the first folding seat 1 and the second folding seat 2 are folded together, rotating the handle 331 causes the drive seat 332, the locking seat 32, and the locking pin 31 to rotate in tandem, causing the locking mechanism 3 as a whole to move toward the locking cavity 4 until the first limiting part 411 and the second limiting part 421 are engaged with the limiting cavity 321 and come into contact with it. At this point, the locking seat 32 completes the locking engagement with the locking cavity 4; otherwise... Rotating the handle 331 in the opposite direction will cause the drive seat 332 and the locking pin 31 to move away from the mounting cavity 4. The locking pin 31 is provided with a limiting pin 311, which is adjacent to the inner side of the locking seat 32. The limiting pin 311 passes through the locking pin 31 and its two ends protrude from the surface of the locking pin 31. The limiting pin 311 abuts against the locking seat 32 and drives the locking seat 32 to move away from the mounting cavity 4, so that the first limiting part 411 and the second limiting part 421 are disengaged from the limiting cavity 321, and the locking seat 32 is released from the locking engagement with the mounting cavity 4.

[0033] In another preferred embodiment, the locking pin 31 and the locking pin cavity are provided with mutually cooperating threads. After the first folding seat 1 and the second folding seat 2 are folded together, by rotating the rotating handle 331, the drive seat 332 and the locking pin 31 are rotated together. The locking pin 31 will not continue to extend into the locking pin cavity 111. Due to the rotation of the locking pin 31, the locking seat 32 will move along the locking pin 31 towards the locking cavity 4 until the first limiting part 411 and the second limiting part 421 are inserted into the limiting cavity 321 and abut against the limiting cavity 321. At this time, the locking seat 32 completes the locking engagement with the locking cavity 4. Conversely, by rotating the rotating handle 331 in the opposite direction, the locking seat 32 moves away from the locking cavity 4, causing the first limiting part 411 and the second limiting part 421 to disengage from the limiting cavity 321, and the locking seat 32 releases the locking engagement with the locking cavity 4.

[0034] In conjunction with the above, the folding device also includes a positioning boss 23 and a positioning groove 13. The positioning boss 23 is located in either the first folding seat 1 or the second folding seat 2, and the positioning groove 13 is located in the other seat. The positioning boss 23 and the positioning groove 13 are correspondingly engaged. Preferably, in this embodiment, the positioning groove 13 is located on the first folding seat 1, and the positioning boss 23 is located on the second folding seat 2. The positioning groove 13 and the positioning boss 23 are embedded and snap-fitted together. In other embodiments, commonly used mounting methods in the prior art, such as magnetic mounting, can also be used.

[0035] In summary, the first folding seat 1 includes a first folding seat body and a first folding assembly cavity 14, and the second folding seat 2 includes a second folding seat body and a second folding assembly cavity 24. When the first folding seat 1 and the second folding seat 2 are locked together, the first folding assembly cavity 14 and the second folding assembly cavity 24 are in relative communication. A first locking part 15 is provided on the inner wall of the first folding assembly cavity 14, and a second locking part 25 is provided on the inner wall of the second folding assembly cavity 24. The first locking part 15 and the second locking part 25 are used to correspondingly engage with the pipe fittings to be assembled, facilitating the implementation of commonly used fixed engagement methods in the prior art, such as end connection and fixed engagement.

[0036] This utility model has a simple structure, low manufacturing cost, quick and labor-saving operation, and eliminates the need for a spring mechanism, thus avoiding the problem of insufficient spring force caused by prolonged use or tight locking.

[0037] The above description is merely a preferred embodiment of the present utility model and does not constitute any limitation on the utility model. Any simple modifications, equivalent changes, or alterations made to the above embodiments based on the technical principles of the present utility model shall still fall within the scope of the technical solution of the present utility model.
