DETAILED DESCRIPTION

[0036] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. It should be understood that the specific embodiments described herein are only used to explain the utility model and are not used to limit the utility model. Based on the embodiments of the utility model, all other embodiments obtained by those skilled in the art without creative work belong to the protection scope of the utility model.

[0037] Embodiment 1:

[0038] like Figures 1 to 4 As shown, this embodiment provides a bracket locking device for a luggage case, comprising:

[0039] An articulated device, the articulated device comprises a fixed seat 2 and a rotating seat 4, the rotating seat 4 is rotatably connected to the fixed seat 2 via a rotating shaft 6; the rotating seat 4 comprises a first position and a second position relative to the fixed seat 2, and the rotating seat 4 is provided with a first locking portion corresponding to the first position and a second locking portion corresponding to the second position; and,

[0040] The locking mechanism comprises a pressing assembly, a locking block 7 and a reset member. The locking block 7 is slidably arranged on the fixing seat 2 along a direction perpendicular to the axis of the rotating shaft 6. Specifically, the fixing seat 2 is provided with a guide groove, and the locking block 7 is slidably arranged along the guide groove; the locking block 7 is provided with a third locking portion;

[0041] When the pressing component is pressed, the pressing component drives the locking block 7 to slide and causes the third locking portion to be separated from the first locking portion or the second locking portion;

[0042] When the pressing assembly is released, the reset member resets the pressing assembly and the locking block 7, and when the rotating seat 4 rotates to the first position, the third locking portion is locked with the first locking portion to keep the rotating seat 4 in the first position; when the rotating seat 4 rotates to the second position, the third locking portion is locked with the second locking portion to keep the rotating seat 4 in the second position.

[0043] When it is applied to a suitcase, the fixed seat 2 is fixedly connected to the case body 1 , and the rotating seat 4 is fixedly connected to the second bracket 13 , so that the second bracket 13 can rotate relative to the case body 1 through the rotating seat 4 .

[0044] In this embodiment, Figure 1 to Figure 2As shown, in order to make it more stable when applied to the box 1, there are two rotating seats 4, which are respectively located on the left and right sides of the fixed seat 2 and rotate synchronously to the first position or the second position; there are two locking blocks 7, and the two locking blocks 7 correspond to the two rotating seats 4 one by one; the pressing component has two driving ends, and the two driving ends drive the two locking blocks 7 respectively. When the pressing component is pressed, the pressing component drives the two locking blocks 7 to slide respectively through the two driving ends. This setting makes it more convenient to control the two locking blocks 7 at the same time through one button 3.

[0045] In this embodiment, Figures 1 to 4 As shown, as a specific structure of the first locking part, the second locking part and the third locking part, the first locking part is the first locking groove 41, the second locking part is the second locking groove 42, and the third locking part is the blocking block 71; when the rotating seat 4 is rotated to the first position, the blocking block 71 is engaged with the first locking groove 41 under the action of the reset member to keep the rotating seat 4 in the first position. At this time, since the locking block 7 is stuck between the rotating seat 4 and the fixed seat 2, the rotating seat 4 cannot rotate relative to the fixed seat 2; when the rotating seat 4 is rotated to the second position, the blocking block 71 is engaged with the second locking groove 42 under the action of the reset member to keep the rotating seat 4 in the second position. At this time, since the locking block 7 is stuck between the rotating seat 4 and the fixed seat 2, the rotating seat 4 cannot rotate relative to the fixed seat 2.

[0046] When the pressing assembly is pressed, the pressing assembly drives the locking block 7 to slide, and the third locking portion slides out of the first locking portion or the second locking portion. After the disengagement, the locking block 7 loses its clamping seat for the rotating seat 4, and the rotating seat 4 can rotate relative to the fixed seat 2.

[0047] Among them, the number of the card blocks 71, the first card slots 41 and the second card slots 42 are equal and there are at least two of them. When the rotating base 4 rotates to the first position, the card blocks 71 are correspondingly inserted into the first card slots 41; when the rotating base 4 rotates to the second position, the card blocks 71 are correspondingly inserted into the second card slots 42.

[0048] The above scheme is preferably: the number of the clamping block 71, the first clamping slot 41 and the second clamping slot 42 are all three, and the three clamping blocks 71 are located on the same straight line, the three first clamping slots 41 are located on the same straight line, and the three second clamping slots 42 are located on the same straight line. One of the clamping blocks 71 is located on the side of the rotating shaft 6 close to the pressing component, and the other two are located on the side of the rotating shaft 6 away from the pressing component. This arrangement allows the clamping blocks 71 to be clamped with the corresponding clamping slots on both sides of the rotating shaft 6, so that the rotating seat 4 is more stable when locked in the first position or the second position.

[0049] In this embodiment, Figures 1 to 4As shown, the reset member is preferably a spring 5, and the specific setting method is that the locking block 7 is provided with a protrusion 73, and the spring 5 is sleeved on the locking block 7 and is located between the protrusion 73 and the rotating shaft 6. The sleeve position of the spring 5 avoids the position of the clamping block 71, so as not to affect the clamping of the clamping block 71 with the corresponding first clamping groove 41 or second clamping groove 42. When the pressing component is pressed, the spring 5 is compressed. After the pressing component is released, the spring 5 is reset and drives the locking block 7 to slide until the third locking portion is locked with the first locking portion or locked with the second locking portion, thereby achieving automatic locking.

[0050] In this embodiment, as a specific structure of the pressing component, the pressing component includes a button 3 and a connecting rod 31 slidably arranged on the fixed base 2, and the driving ends of the pressing component are respectively the two ends of the connecting rod 31; the two ends of the connecting rod 31 are respectively connected to two locking blocks 7, and when the button 3 is pressed, the button 3 drives the two locking blocks 7 to slide through the connecting rod 31.

[0051] The specific structure of the connection between the connecting rod 31 and the locking block 7 may be that a slot is provided on the locking block 7, and the end of the connecting rod 31 is inserted into the corresponding slot.

[0052] In this embodiment, in order to facilitate the sliding of the locking block 7 along the fixing seat 2 , a guide hole 72 is provided on the locking block 7 , and the rotating shaft 6 is disposed through the guide hole 72 .

[0058] Working principle description:

[0059] When it is necessary to switch the second bracket 13 from the folded state to the unfolded state, the user presses the button 3, and the button 3 drives the two locking blocks 7 to slide through the connecting rod 31, so that the blocking block 71 disengages from the first slot 41, and the spring 5 is compressed. At this time, the rotating seat 4 can rotate relative to the fixed seat 2. When the user rotates the second bracket 13 to the unfolded state, the button 3 is released, and under the resetting action of the spring 5, the locking block 7 is driven to slide and reset, and the locking block 7 drives the connecting rod 31 and the button 3 to reset. After the locking block 7 is reset, the blocking block 71 on the locking block 7 is engaged in the second slot 42, so that the rotating seat 4 is locked in the second position, thereby locking the second bracket 13 in the unfolded state.

[0060] The present utility model is not limited to the above optional implementation modes. Under the premise of not conflicting with each other, the various schemes can be combined arbitrarily. Anyone can derive other forms of products under the inspiration of the present utility model.
