[0048] In the following description, only certain exemplary embodiments are briefly described. As those skilled in the art will recognize, the described embodiments can be modified in various ways without departing from the spirit or scope of this application. Therefore, the drawings and description are considered to be exemplary in nature and not restrictive.

[0049] See Figures 1-11 This invention illustrates a preferred embodiment of a locking pin adjustment device, comprising:

[0050] Door frame 1, door frame 1 has a first connecting hole 11;

[0051] Locking pin 2;

[0052] Adjusting seat 4 supports locking pin 2. Adjusting seat 4 has an adjusting hole 411 that extends vertically. The vertical dimension of adjusting hole 411 is greater than its horizontal dimension; that is, adjusting hole 411 is an elongated hole extending vertically.

[0053] The head of the locking component 5 is located on the side of the adjusting seat 4 away from the door frame 1. The outer diameter of the head of the locking component 5 is larger than the lateral dimension of the adjusting hole 411. The rod of the locking component 5 can be vertically moved through the adjusting hole 411, and the rod of the locking component 5 can be detachably connected to the first connecting hole 11 to connect the adjusting seat 4 and the door frame 1 together.

[0054] This utility model discloses a locking pin adjustment device. A first connecting hole 11 is provided on the first door frame 1, an adjustment hole 411 is provided on the adjustment seat 4 supporting the locking pin 2, and a locking component 5 connects the adjustment hole 411 and the first connecting hole 11. During installation, the head of the locking component 5 is positioned on the side of the adjustment seat 4 facing away from the door frame 1. The rod of the locking component 5 passes through the adjustment hole 411 and the first connecting hole 11 in sequence, thereby fixing the adjustment seat 4 to the door frame 1 and achieving a fixed connection between the locking pin 2 and the door frame 1. When the locking pin 2 and the lock body 10 on the door 9 are not aligned, the locking component 5 can be loosened, allowing the adjustment seat 4 to move vertically along the door frame 1, adjusting the position of the locking pin 2 until it is accurately aligned with the lock body 10, and then the locking component 5 can be re-locked. Thus, by adjusting the position of the locking pin 2, reliable cooperation between the locking pin 2 and the lock body 10 is ensured, making the door 9 close tightly, effectively preventing the door 9 from accidentally opening during driving and ensuring driving safety.

[0055] See Figures 7-8 In one embodiment, the door frame 1 further has a receiving cavity 12, a first notch 13 and a second notch 14, the first notch 13 and the second notch 14 are both connected to the receiving cavity 12, and the second notch 14 is connected to the door opening 15 of the door frame 1.

[0056] Adjustment seat 4 includes:

[0057] Main seat 41, the main seat 41 is disposed on the door frame 1, the main seat 41 covers the first notch 13, and the main seat 41 has an adjustment hole 411; and

[0058] Support body 42 is disposed on main body 41 and inside receiving cavity 12. Support body 42 enters and exits receiving cavity 12 through first notch 13.

[0059] The locking pin 2 is mounted on the support body 42, with at least a portion of the locking pin 2 passing through the second notch 14, so that at least a portion of the locking pin 2 is exposed in the door opening 15 of the door frame 1. Thus, during installation, the support body 42 extends into the receiving cavity 12 through the first notch 13, while at least a portion of the locking pin 2 extends into the door opening 15 of the door frame 1 through the second notch 14. The main seat 41 covers the first notch 13, thereby concealing the support body 42 within the door frame 1. This avoids the adjusting seat 4 and the locking pin 2 occupying excessive external space of the door frame 1, thus saving external space. Furthermore, when the support body 42 is installed in the receiving cavity 12, the locking pin 2 can be positioned in the second notch 14, making installation simple, convenient, and greatly improving installation efficiency.

[0060] See Figures 9-11 In one embodiment, the adjusting seat 4 further includes:

[0061] The connector 43 has a first side connected to the main seat 41 and a second side connected to the support 42. The second side of the connector 43 is adjacent to its first side and is located within the receiving cavity 12. Because the connector 43 is positioned between the main seat 41 and the support 42, it strengthens the structural integrity of both, preventing deformation and ensuring reliable connection between the adjusting hole 411 and the first connecting hole 11. It also ensures stable engagement between the locking pin 2 and the locking body 10.

[0062] See Figures 9-11 In one embodiment, there are two connectors 43, which are placed on both sides of the locking pin 2 to prevent the main seat 41 and the support 42 from deforming on one side and to ensure that the locking pin 2 and the locking body 10 are accurately aligned for a long time.

[0063] To facilitate fixing the locking pin 2 to the support body 42, see [reference needed]. Figures 9-11 In one embodiment, the support 42 has a second connecting hole (not shown in the figure);

[0064] The locking pin 2 passes through the second connecting hole, and the locking pin 2 is provided with a first external thread (not shown in the figure) and a second external thread (not shown in the figure);

[0065] The locking pin adjustment device also includes:

[0066] The first locking nut 6 is sleeved on the first external thread portion and abuts against the first side of the support body 42.

[0067] The second locking nut 7 is sleeved on the second external thread and abuts against the second side of the support body 42.

[0068] Of course, in other embodiments, the locking pin 2 can also be fixed to the support body 42 by welding, or the locking pin 2 and the support body 42 can be integrally formed.

[0069] To improve the connection stability between the adjusting seat 4 and the door frame 1, see [reference needed]. Figures 1-11 In one embodiment, there are two sets of first connecting holes 11, adjusting holes 411 and locking components 5. The two sets of first connecting holes 11 are arranged vertically spaced apart, and the locking components 5 connect the corresponding adjusting holes 411 and the first connecting holes 11.

[0070] Of course, in other embodiments, the number of the first connecting hole 11, the adjusting hole 411 and the locking component 5 can be any suitable number of one set, three sets or more.

[0071] In one embodiment, two sets of first connecting holes 11 are respectively placed on the upper and lower sides of the first notch 13.

[0072] In one embodiment, the rod portion of the locking member 5 is threadedly connected to the first connecting hole 11.

[0073] A preferred embodiment of this utility model provides a carriage, comprising:

[0074] 8-section box;

[0075] The aforementioned lock adjustment device has the door frame 1 mounted on the body 8; and

[0076] The side door 9 is movably mounted on the door frame 1. The side door 9 is used to open or close the door opening 15 of the door frame 1. The side door 9 is equipped with a lock body 10. When the side door 9 closes the door opening 15, the lock pin 2 cooperates with the lock body 10.

[0077] The carriage of this utility model, employing the aforementioned locking pin adjustment device, also features a first connecting hole 11 on the first door frame 1, an adjustment hole 411 on the adjustment seat 4 supporting the locking pin 2, and a locking component 5 connecting the adjustment hole 411 and the first connecting hole 11. During installation, the head of the locking component 5 is positioned on the side of the adjustment seat 4 facing away from the door frame 1, and the rod of the locking component 5 passes through the adjustment hole 411 and the first connecting hole 11 in sequence, thereby fixing the adjustment seat 4 to the door frame 1 and achieving a fixed connection between the locking pin 2 and the door frame 1. When the locking pin 2 and the lock body 10 on the carriage door 9 are not aligned, the locking component 5 can be loosened, allowing the adjustment seat 4 to move vertically along the door frame 1, adjusting the position of the locking pin 2 until the locking pin 2 and the lock body 10 are accurately aligned, and then the locking component 5 can be re-locked. Therefore, by adjusting the position of the locking pin 2, the locking pin 2 and the lock body 10 are reliably matched, so that the door 9 is closed tightly, thereby effectively preventing the door 9 from being opened accidentally during driving and ensuring driving safety.

[0078] A preferred embodiment of this utility model provides a trackless human vehicle, including the aforementioned locking column adjustment device.

During installation, the head of the locking component 5 is positioned on the side of the adjustment seat 4 facing away from the door frame 1, and the rod of the locking component 5 passes through the adjustment hole 411 and the first connecting hole 11 in sequence, thereby fixing the adjustment seat 4 to the door frame 1 and achieving a fixed connection between the locking pin 2 and the door frame 1. When the locking pin 2 and the lock body 10 on the door 9 are not aligned, the locking component 5 can be loosened, allowing the adjustment seat 4 to move vertically along the door frame 1, adjusting the position of the locking pin 2 until the locking pin 2 and the lock body 10 are accurately aligned, and then the locking component 5 can be re-locked. Therefore, by adjusting the position of the locking pin 2, the locking pin 2 and the lock body 10 are reliably matched, so that the door 9 is closed tightly, thereby effectively preventing the door 9 from being opened accidentally during driving and ensuring driving safety.
