[0037] The specific implementation of the present invention will be described in detail below with reference to specific embodiments.

[0038] See attached document Figure 1-6 A box-type locking structure includes a first connector 1 and a second connector 2, which are connected to both sides of the box and are respectively disposed on the parallel end faces of the box, facilitating subsequent box-type installation operations.

[0039] The bottom support 3 is provided with at least one guide component 4, and the guide component 4 is located on one side of the bottom support 3. Please refer to the following. Figure 2On the left side, the guide component 4 is provided with at least one protrusion, and the first connector 1 is provided with a groove that is complementary in shape to the protrusion. The outline size of the protrusion is adapted to the accommodating space of the groove, and the two are interlocked to achieve a detachable connection between the guide component 4 and the first connector 1. The other end of the bottom support 3 is rotatably connected to the locking mechanism 6 through the first rotating shaft 5, and the locking mechanism 6 is matched and connected to the second connector 2.

[0040] When this device is in operation, the first connector 1 and the second connector 2 are installed on both sides of the box that needs to be locked and disassembled. The bottom support 3 is installed on the platform to be installed. When installing the box, align the bottom of the box with the bottom support 3, and align the guide component 4 with the first connector 1 for limiting. Then, connect and engage the locking mechanism 6 on the other side of the box with the second connector 2. The following is an example of a common case. This device is used to fix a pickup truck storage box. First, connect the first connector 1 and the second connector 2 to both sides of the pickup truck storage box. Install the bottom support 3 in a suitable position in the pickup truck bed. When it is necessary to fix the pickup truck storage box, align the pickup truck storage box with the guide component 4, and then connect the locking mechanism 6 with the second connector.

[0041] Please refer to this carefully. Figure 5 The bottom support 3 includes a concave support plate 31. The top of the concave support plate 31 is connected to the load-bearing base plate 32. One end of the concave support plate 31 is connected to the guide component 4. One end of the load-bearing base plate 32 is connected to the first rotating shaft 5. The concave support plate 31 and the load-bearing base plate 32 have aligned first mounting holes 33. The bottom of the concave support plate 31 can be connected to the position where the box needs to be placed. The concave support plate 31 and the load-bearing base plate 32 are connected by bolts at the first mounting holes 33. The box is placed directly on the load-bearing base plate 32. The concave support plate 31 and the load-bearing base plate 32 can also be directly welded together.

[0042] Please refer to this carefully. Figure 5 The guide assembly 4 includes a supporting vertical plate 41, with a guide pin 42 connected to the inner side of the supporting vertical plate 41. The first connecting member 1 includes a guide plate 43, with a guide hole 44 in the middle of the guide plate 43. The guide hole 44 matches the guide pin 42. The guide plate 43 is connected to the box body through a second mounting hole 45. The guide assembly 4 positions one side of the box body through the cooperation of the guide pin 42 and the guide hole 44. When installing the box body, the guide pin 42 on the side of the box body is inserted into the guide hole 44. It should be noted that multiple guide pins 42 and guide holes 44 can be set according to the installation requirements of the box body to improve the stability when the two are matched.

[0043] Please refer carefully to the locking process of the locking mechanism 6. Figure 2-4The engaging mechanism 6 includes a rotating connecting block 61. One end of the rotating connecting block 61 is rotatably connected to the first rotating shaft 5 at the end of the load-bearing base plate 32, and the other end of the rotating connecting block 61 is rotatably connected to a locking plate 62. The locking plate 62 has a concave notch 63 at the connection point with the rotating connecting block 61, and a latching block 64 is provided at the top of the locking plate 62. The second connecting member 2 includes a "J"-shaped latching block 65, and the latching block 64 and the "J"-shaped latching block 65 are interlocked. Both ends of the connecting block 61 are rotatably connected, ensuring that the snap-fit ​​plate 62 rotates and locks around the two pivots. When locking is required, the snap-fit ​​block 64 is rotated around the pivot of the load-bearing base plate 32 in the direction of the "J"-shaped snap-fit ​​block 65. Then, the concave part of the snap-fit ​​block 64 is aligned with the "J"-shaped snap-fit ​​block 65 and moved downward. The rotation of the connecting block 61 causes the snap-fit ​​block 64 and the "J"-shaped snap-fit ​​block 65 to engage with each other. At this time, the tilt angle of the connecting block 61 is towards the concave support plate 31, forming a locking structure.

[0044] Please refer to this carefully. Figure 6 The rear end of the snap-fit ​​plate 62 is connected to the actuating plate 66, which allows the operator to rotate the snap-fit ​​block through the actuating plate 66, thereby connecting the "J"-shaped snap-fit ​​block 65 with the snap-fit ​​block 64.

[0045] Please refer to this carefully. Figure 5-6 The actuating plate 66 and the locking plate 62 are integrally formed, which helps to ensure the stability of the locking plate 62.

[0046] Please refer to this carefully. Figure 6 It also includes a rotation limiting pin 7, which is connected to the bottom of the snap-fit ​​plate 62. The concave notch 63 at the bottom of the concave support plate 31 cooperates with the rotation limiting pin 7. In order to ensure the stability of the box after snap-fit, the rotation limiting pin 7 is provided. After the rotation limiting pin 7 rotates and snaps into the concave notch 63, it can limit the snap-fit ​​mechanism 6.

[0047] Please refer to this carefully. Figure 6 The rotating limiting pin 7 and the locking plate 62 are connected by rubber damping. The rear end of the rotating limiting pin 7 is connected to the rotating handle 71, and the front end of the rotating limiting pin 7 is connected to the locking strip 72. When the locking mechanism 6 needs to be limited, the locking block 64 and the "J"-shaped locking block 65 are first locked together. Then, the rotating limiting pin 7 is rotated by rotating the rotating handle 71, so that the locking strip 72 is rotated into the corresponding concave notch 63 at the bottom. In this way, even if the box is subjected to pressure from the side, the locking plate 62 will not slide outward under the action of the locking strip 72, thereby ensuring the stability of the box.

[0048] In this embodiment, the "J"-shaped locking block 65 is detachably connected to the box body. The "J"-shaped locking block 65 can be bolted to any box body, making it highly adaptable.

[0049] The above-described embodiments are merely illustrative of certain implementations of this utility model, and their descriptions are relatively specific and detailed. However, they should not be construed as limiting the scope of this utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these modifications and improvements all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model patent should be determined by the appended claims.
