Therefore, the above terms should not be understood as limiting the present application.

[0056] The present application is further described in detail below in conjunction with the accompanying drawings. Figures 1 to 11 illustrate.

[0057] The present application provides a baby-walking luggage case bracket locking mechanism, which acts in a baby-walking luggage case 1, wherein the baby-walking luggage case 1 includes a frame 2 and a box body 3, wherein the frame 2 is connected to the box body 3, and the frame 2 includes a connecting seat 4 and a bracket 5, wherein the connecting seat 4 is connected to the box body 3, and the bracket 5 is connected to the box body 3. Figure 1 , Figure 2 As shown, the bracket 5 is connected to both sides of the connecting seat 4, the lower end of the bracket 5 is provided with a roller, the lower end of the connecting seat 4 is provided with a roller, the connecting seat 4 is fixedly connected to the box body 3, the bracket 5 is rotatably connected to the connecting seat 4, and the bracket 5 can be rotated at a certain angle relative to the box body 3, so that the bracket 5, the box body 3, and the ground form a triangular structure, which increases the support points of the baby walking suitcase 1, so that when the user pushes the suitcase, the movement of the suitcase is more stable and the required force is smaller, thereby improving the user's convenience; in the present application, a locking assembly 6 is provided, one end of the locking assembly 6 is connected to the connecting seat 4, and the other end is connected to the bracket 5, that is, the connecting seat 4 is connected to the connecting seat 4 through the locking assembly 6, and then the connecting seat 4 and the bracket 5 are locked;

[0058] Specifically, Figures 3 to 6 As shown, the locking assembly 6 is arranged in the connecting seat 4, and an adjustment groove is provided in the middle of the connecting seat 4. The adjustment groove is opened on the inner and outer end surfaces of the side wall of the connecting seat 4 along the radial direction. The end of the locking assembly 6 passes through the adjustment groove and is at least partially exposed to the outside of the connecting seat 4. The other end of the locking assembly 6 is connected to the bracket 5; wherein, as Figure 7As shown, at least two slots 22 are provided on the bracket 5, and the slots 22 are distributed along the axial direction. There are baffles between the slots 22 and the slots 22, and the locking assembly 6 is inserted into one of the slots 22, so that the connection position between the bracket 5 and the connecting seat 4 is changed, that is, the connection angle of the bracket 5 relative to the connecting seat 4 (box 3) can be adjusted, that is, an angle can be made between the bracket 5 and the box 3, and the bracket 5 and the connecting seat 4 work together to increase the fulcrum of the baby walking suitcase 1 in contact with the ground, and the bracket 5 can also be made to fit with the box 3, so that the connecting seat 4 can act alone on the movement of the baby walking suitcase 1.

[0059] In this embodiment, if Figure 7 As shown, the bracket 5 is provided with five slots 22, that is, the connection angles between the bracket 5 and the box 3 are five, that is, the rotation degrees of the bracket 5 are five, such as Figure 7 As shown, the axial length of the outer ring retaining ring corresponding to the two slots 22 is relatively low, which reduces the blocking length between the locking assembly 6 and facilitates the disengagement or insertion of the bracket 5 and the locking assembly 6.

[0060] In this embodiment, if Figure 3 , Figure 4 As shown, the locking assembly 6 is divided into a first locking portion 7 and a second locking portion 8. The first locking portion 7 and the second locking portion 8 have the same structure, but are symmetrically arranged along the center of the connecting seat 4. The first locking portion 7 and the second locking portion 8 are distributed along the axial direction. The facing ends of the first locking portion 7 and the second locking portion 8 are both located in the adjusting groove, and at least part of them pass through the adjusting groove to be exposed to the outside of the connecting seat 4. The other ends of the first locking portion 7 and the second locking portion 8 are respectively connected to the brackets 5 at both ends, thereby realizing the connection and locking of the brackets 5 at both ends of the connecting seat 4; wherein the first locking portion 7 and the second locking portion 8 are slidably connected to the connecting seat 4, and the first locking portion 7 and the second locking portion 8 can be displaced in the axial direction. The user can adjust the first locking portion 7 and the second locking portion 8 by adjusting the first locking portion 7 and the second locking portion 8. The part of the locking portion 8 exposed to the outside of the connecting seat 4 applies a force in the axial direction, which can conveniently and easily pull the first locking portion 7 and the second locking portion 8 to move in the axial direction, and then enable them to enter the bracket 5, or slide from the bracket 5, to achieve locking or unlocking of the bracket 5 and the connecting seat 4; in this embodiment, by dividing the locking component 6 into two parts, the two ends of the frame 2 are acted on separately, which actually shortens the axial length of the locking component 6 on the bracket 5, that is, the length from the adjustment groove to the connection position of the locking portion and the bracket 5 is reduced. Due to the reduced length, the force transmission length is shorter, so that the locking component 6 has a greater force on the bracket 5 and is less likely to be damaged, thereby achieving a better locking effect.

[0061] Furthermore, in this embodiment, one or two adjustment slots may be provided; Figure 5As shown, when there are two adjustment grooves, they are the first adjustment groove 20 and the second adjustment groove 21, the first adjustment groove 20 and the second adjustment groove 21 are spaced apart in the axial direction, one end of the first locking portion 7 is at least partially located in the first adjustment groove 20, the first locking portion 7 at least partially passes through the first adjustment groove 20 and is exposed to the outside of the connecting seat 4, one end of the second locking portion 8 is at least partially located in the second adjustment groove 21, the second locking portion 8 at least partially passes through the second adjustment groove 21 and is exposed to the outside of the connecting seat 4; a partition is provided between the first adjustment groove 20 and the second adjustment groove 21, as shown in FIG. Figure 4 As shown, a stopper is correspondingly provided in the partition, and the stopper is located between the first locking part 7 and the second locking part 8. The stopper cooperates with the partition to limit the displacement between the first locking part 7 and the second locking part 8, thereby avoiding collision when the first locking part 7 and the second locking part 8 move toward each other at the same time, thereby ensuring the locking stability of the locking assembly 6 on the bracket 5.

[0062] like Figures 4 to 6 As shown, the locking assembly 6 is further described; the first locking portion 7 includes an adjusting member 10 and a limiting member 9, the adjusting member 10 and the limiting member 9 are axially arranged, and the adjusting member 10 and the limiting member 9 are both slidably connected to the connecting seat 4, wherein one end of the limiting member 9 is fixedly connected to the adjusting member 10, and the end of the limiting member 9 away from the adjusting member 10 is inserted into the slot 22 of the bracket 5 to achieve connection with the bracket 5; the end of the adjusting member 10 away from the limiting member 9 passes through the adjusting groove and is exposed to the outside of the connecting seat 4, and by applying an axial force to the adjusting member 10, the limiting member 9 can be pulled or pushed to move in the axial direction to achieve locking or unlocking of the limiting member 9 and the bracket 5.

[0063] Specifically, Figure 4 , Figure 6 , Figure 8 As shown, the limiting member 9 is provided with a second connecting portion 14 and a limiting portion 15, the end of the second connecting portion 14 is provided with a connecting protrusion 32 protruding toward the axial direction of the connecting seat 4, the limiting portion 15 protrudes outward along the axial direction, and the limiting portion 15 is used to be inserted into the slot 22 to limit the bracket 5, so that the bracket 5 is fixed relative to the connecting seat 4; Fig. 9 As shown, the adjusting member 10 includes a first connecting portion 12 and an adjusting portion 13. A collar 31 is provided at the end of the first connecting portion 12. The collar 31 is sleeved on a connecting protrusion 32 of the second connecting portion 14. The inner wall of the collar 31 fits with the outer wall of the connecting protrusion 32, thereby realizing a relatively fixed connection between the adjusting member 10 and the stopper 9. The other end of the second connecting portion 14 is connected to the adjusting portion 13. Figure 4As shown, the adjusting portion 13 protrudes radially outward, the adjusting portion 13 is a convex block, the adjusting portion 13 is located in the adjusting groove, and the adjusting portion 13 at least partially passes through the adjusting groove and is exposed to the outside of the connecting seat 4, and in this embodiment, the axial length of the adjusting groove is greater than the axial width of the adjusting portion 13, so that the adjusting portion 13 has a sliding space, that is, the difference between the length of the adjusting groove and the axial width of the adjusting portion 13, that is, the sliding length of the adjusting member 10 along the axial direction, that is, the axial sliding length of the limiting member 9;

[0064] It should be noted that the minimum sliding length needs to ensure that the limit member 9 can be inserted into the slot 22, and block and limit the slot 22 in the radial direction, so that the bracket 5 can be locked with the connecting seat 4; the maximum sliding length needs to ensure that the limit member 9 can be completely disengaged from the slot 22, and the slot 22 cannot be completely blocked and limited in the radial direction, so that the bracket 5 can be disengaged from the connecting seat 4; in the natural state, that is, when the sliding length is at the minimum value, the adjusting member 10 is in the absence of external force, and the limit member 9 acts on the bracket 5. When the user applies a force to the adjusting member 10, that is, when the sliding length is at the maximum value, it is necessary to ensure that the limit member 9 is completely pulled out of the slot 22.

[0065] Further, such as Figure 4 , Figure 6 , Figure 8 As shown, the stopper 9 further includes a rebound portion 16, which is disposed on the second connecting portion 14 and is used to mount the first spring 17. The rebound portion 16 is disposed along the axial direction. Figure 6 , Figure 8 As shown, in the radial direction, the rebound portion 16 is provided with a baffle, so as to limit the first spring 17 and ensure the stability of the first spring 17 placed in the rebound portion 16; Figure 6 As shown, one end of the first spring 17 is fitted with the limit member 9, and the other end is fitted with the connecting seat 4, that is, when the limit member 9 moves axially, the end of the first spring 17 fitted with the limit member 9 moves with the limit member 9, and the end of the first spring 17 fitted with the connecting seat 4 remains stationary. The first spring 17 generates an elastic force after being compressed. When the external force applied to the limit member 9 disappears, the elastic force generated by the first spring 17 pushes the limit member 9 to reset, so that the limit member 9 has an automatic reset function, thereby ensuring the locking effect of the limit member 9 on the bracket 5, thereby ensuring the connection stability of the bracket 5 and the connecting seat 4.

[0066] Further, such as Figure 4 , Fig. 9As shown, the adjusting member 10 is provided with a first slide groove 18, which is arranged in the middle of the first connecting portion 12, that is, the first slide groove 18 is located between the collar 31 and the adjusting portion 13, and two first slide grooves 18 are provided, which are respectively arranged on one side of the first connecting portion 12 away from the adjusting portion 13, and the length direction of the first slide groove 18 is parallel to the axial direction, and the adjusting member 10 can slide along the axial direction; Figure 4 As shown, a first limiting column 19 is provided on the connecting seat 4, and the first limiting column 19 is at least partially located in the first sliding groove 18. The first limiting column 19 and the first sliding groove 18 act together to limit and guide the sliding of the adjusting member 10, thereby ensuring the sliding stability of the adjusting member 10.

[0067] like Figures 4 to 6 As shown, in the present application, the locking assembly 6 also includes a locking member 11, the locking member 11 is connected to the limiting member 9, and the locking member 11 is radially slidably connected to the connecting seat 4; the locking member 11 is also provided with a mounting hole 30, and the mounting hole 30 axially penetrates the locking member 11, and the bracket 5 is provided with a mounting column 29, and the mounting column 29 is at least partially inserted into the mounting hole 30, so as to realize the connection and positioning of the bracket 5 and the locking member 11, so that the connection between the bracket 5 and the connecting seat 4 can be further stabilized; as shown in FIG. Figure 6 As shown, a locking groove 23 is provided on the locking member 11, and the locking groove 23 penetrates the locking member 11 along the axial direction, and the limiting portion 15 of the limiting member 9 passes through the locking groove 23 and enters the slot 22, wherein the side of the limiting portion 15 facing the axis center direction is in contact with the inner wall of the locking groove 23, and the side surface of the limiting portion 15 in contact with the locking groove 23 is an inclined surface, and the side surface of the locking groove 23 in contact with the limiting portion 15 is an inclined surface, and the inclined surface of the limiting portion 15 is consistent with the inclined surface of the locking groove 23, and the outer thickness of the limiting portion 15 is greater than the inner thickness, and the angle between the inclined surface and the axis of the connecting seat 4 is an acute angle, and the radial thickness of the limiting portion 15 gradually decreases from the outside to the inside; Through the cooperation between the limiting portion 15 and the inclined surface of the locking groove 23, when the limiting member 9 moves axially, the axial force of the limiting member 9 is transmitted to the locking member 11 through the inclined surface and converted into a radial force, so that the locking member 11 slides radially, so that the locking member 11 releases the locking of the limiting member 9, so that the limiting member 9 can be disengaged from the slot 22 to release the locking of the bracket 5 by the limiting member 9. The locking member 11 locks the limiting member 9 in the radial direction, and together with the limiting member 9, the locking effect of the locking assembly 6 on the bracket 5 is better, so that the bracket 5 and the connecting seat 4 are not easy to be disengaged, and the stability and safety of the baby walking suitcase 1 are better.

[0068] Further, such as Fig.10 , Fig.11As shown, the locking member 11 is provided with a second slide groove 24, the length direction of the second slide groove 24 is parallel to the sliding direction of the locking member 11, and the second slide groove 24 is provided with two, which are respectively arranged on both sides of the locking groove 23. The second slide groove 24 axially penetrates the locking member 11, and a second limiting column 25 is provided on the connecting seat 4. The second limiting column 25 is at least partially located in the second slide groove 24. The second slide groove 24 and the second limiting column 25 act to limit and guide the sliding of the locking member 11, thereby ensuring the sliding stability of the locking member 11.

[0069] like Figure 6 , Figure 10 to Figure 11 As shown, the locking member 11 is provided with a guide column 26, which is arranged radially. The guide column 26 is arranged at one end of the locking member 11 away from the limiting member 9, and the length extension direction of the guide column 26 is parallel to the length direction of the second slide groove 24. Figure 6 As shown, a second spring 27 is sleeved on the guide column 26, and the guide column 26 has a guiding and stabilizing connection function for the second spring 27. A limit block 28 is provided on the connecting seat 4, and the limit block 28 is used to limit the second spring 27 on the guide column 26. The second spring 27 is located between the guide column 26 and the locking member 11, and one end of the second spring 27 is in contact with the limit block 28, and the other end is in contact with the locking member 11. By arranging the second spring 27, the locking member 11 has an automatic resetting function in the radial direction, which can ensure the locking effect of the locking member 11 on the limit member 9.
