[0039] Embodiment 1

[0040] Reference Figures 1 to 7This embodiment provides a stacking connection system comprising two stacking connection structures symmetrically arranged. Each stacking connection structure includes a first connecting portion 11 and a second connecting portion 2. The first connecting portion 11 is located on the upper object 3, and the second connecting portion 2 is located on the lower object 4; wherein the upper object 3 is stacked on top of the lower object 4. Of course, this invention does not limit the specific number of stacking connection structures in the stacking connection system or their relative positional relationship when multiple stacking connection structures are present, as long as the stacking connection system includes at least one stacking connection structure. The symmetrical arrangement of the two stacking connection structures effectively locks the stacked upper object 3 and lower object 4, while also facilitating operator operation (the operator can unlock both stacking connection structures simultaneously with both hands; if there are more than two, the operator must perform at least two unlocking operations).

[0041] The stacked connection structure will be described in detail below. It should be noted that, unless otherwise specified, the following description of this embodiment refers to a single stacked connection structure.

[0042] like Figure 5 As shown, the first connecting portion 11 includes a card interface 11, an abutment portion 12, and a limiting receiving groove. The first connecting portion 11 is directly disposed on the upper object 3, and preferably located on the side of the upper object 3 and near the bottom.

[0043] The second connecting part 2 includes a base 21, a sliding switch 22, a rotary knob 23, and an elastic element. The second connecting part 2 is preferably located on the side of the lower object 4 and near the top.

[0044] The sliding switch 22 is slidably connected to the object 4 below, meaning the sliding switch 22 can slide relative to the object 4 below. Specifically, the base 21 can be connected to the object 4 below, and the sliding switch 22 can be slidably connected to the base 21 (i.e., the sliding switch 22 is indirectly slidably connected to the base 21). More specifically, such as... Figure 3As shown, a base receiving groove 41 is provided on the side near the top of the object 4 below, and the base 21 is installed in the base receiving groove 41. The top of the base receiving groove 41 is empty to allow for the installation of components such as the sliding switch 22 without hindering their movement. A guide rail 411 and a limiting protrusion 412 are provided on the inner wall of the base receiving groove 41, and the base 21 has corresponding guide grooves 212 and limiting recesses. Inserting the base 21 into the base receiving groove 41 completes the installation of the base 21. During insertion, the guide groove 212 can align with the guide rail 411. After the guide rail 411 enters the guide groove 212, the sliding guide between the guide rail 411 and the guide groove 212 guides the insertion of the base 21 into the base receiving groove 41. When the limiting protrusion 412 is inserted into the limiting recess, the base 21 is fully inserted, completing the installation of the base 21. After the base 21 is inserted into place, the engagement of the limiting protrusion 412 and the limiting groove can limit the position of the base 21 on the object 4 below (preventing the base 21 from moving relative to the object 4 below). Simultaneously, the engagement of the guide rail 411 and the guide groove 212, and the base receiving groove 41 on the base 21 itself, also limit the position of the base 21 on the object 4 below. Of course, in other embodiments, other connection methods can be used between the base 21 and the object 4 below, such as screw connection, or the base 21 can be omitted, with the sliding switch 22 directly slidably connected to the object 4 below, etc. This invention does not limit the specific way the sliding switch 22 is slidably connected to the object 4 below.

[0045] A slide rail 211 is provided on the slide switch 22, and a slide groove 223 is provided on the base 21. The slide rail 211 is slidably connected within the slide groove 223, thereby achieving a sliding connection between the slide switch 22 and the base 21. The slide switch 22 is provided with a corresponding latching part 221 to the card interface 11. When the latching part 221 is inserted into the card interface 11, the stacked connection structure is in a locked state; when the latching part 221 is removed from the card interface 11, the stacked connection structure is in an unlocked state. For ease of description, the direction in which the latching part 221 is inserted into the card interface 11 is referred to as the first direction. Preferably, when the object 4 below is placed on the ground, the first direction is located in the horizontal plane.

[0046] An elastic element is disposed between the base 21 and the sliding switch 22, used to drive the sliding switch 22 to insert the latching part 221 into the corresponding card slot 11. That is, the elastic force of the elastic element allows the stacked connection structure to remain in the state where the latching part 221 is inserted into the card slot 11 without the influence of external force, i.e., it remains in the locked state. Preferably, in this embodiment, the elastic element is a compression spring 24, with both ends of the compression spring 24 abutting against the base 21 and the sliding switch 22 respectively, and the end of the compression spring 24 abutting against the sliding switch 22 is located in the first direction of the end of the compression spring 24 abutting against the base 21. Of course, other elastic elements and other arrangements of elastic elements can be used in other embodiments, and there is no limitation here.

[0047] Preferably, the latching part 221 has a guide surface 2211 that slopes downwards in a first direction. Thus, when the operator moves the upper object 3 onto the lower object 4, the bottom of the upper object 3 first abuts against the guide surface 2211. Under the action of the guide surface 2211, the sliding switch 22 overcomes the resistance of the elastic element and moves in the opposite direction to the first direction until the upper object 3 is in place. At this point, the latching part 221 is aligned vertically with the card interface 11, allowing the latching part 221 to insert into the card interface 11 under the action of the elastic element, achieving self-locking. In other words, the guide surface 2211 allows the process of placing the upper object 3 onto the lower object 4 to be utilized itself, eliminating the need for additional external force to unlock the stacked connection structure during this process.

[0048] The rotary knob 23 is rotatably connected to the slide switch 22. Specifically, the rotary knob 23 is provided with a rotating shaft 222, and the slide switch 22 is provided with a corresponding mounting hole 233. The rotating shaft 222 is installed in the mounting hole 233 and can rotate in the mounting hole 233, thereby realizing the rotatable connection between the rotary knob 23 and the slide switch 22.

[0049] The rotary knob 23 has a limiting part 232 and a force-receiving part 231. The force-receiving part 231 is used to receive external force to drive the slide switch 22 to slide against the resistance of the elastic element, and the force-receiving part 231 can also provide a force to drive the rotary knob 23 to rotate when it is subjected to external force. In the unlocked fixed state, the limiting part 232 on the rotary knob 23 abuts against the locking part 221, and at this time the locking part 221 leaves the card interface 11, and the rotary knob 23 rotates a certain angle relative to the unlocked state (the unlocked state is achieved as soon as the locking part 221 exits the card interface 11; for ease of description, this special state is referred to as the unlocked fixed state). That is, when the operator applies external force to the force-receiving part 231, the external force will cause the slide switch 22 to slide, so that the locking part 221 on the slide switch 22 will leave the card interface 11, unlocking and locking. On the other hand, it will drive the rotary knob 23 to rotate, so that the limiting part 232 on the rotary knob 23 can abut against the abutting part 12. When the limiting part 232 abuts against the abutting part 12, the external force can be released. At this time, the locking part 221 has withdrawn from the card interface 11, and because the limiting part 232 abuts against the abutting part 12, the slide switch 22 cannot slide back and remains in the unlocked state (specifically, the unlocked fixed state).

[0050] In the locked state, the limiting part 232 is housed within the limiting receiving groove. When the operator applies external force to the force-receiving part 231, before the limiting part 232 retracts from the limiting receiving groove, the limiting part 232 on the rotary knob 23 is restricted by the inner wall of the limiting receiving groove and will not rotate or will rotate only slightly. After the limiting part 232 retracts from the limiting receiving groove, the external force causes the rotary knob 23 to rotate, and the limiting part 232 quickly rotates to a position that can abut against the abutting part 12. Then, the external force is released, and under the action of the elastic element, the limiting part 232 will abut against the sliding switch 22, thus preventing the sliding switch 22 from moving further. Specifically, the limiting receiving groove can be provided in the first direction of the abutting part 12 and located below the abutting part 12. The limiting receiving groove can be connected downward to the bottom surface of the lower object 4. That is, the limiting receiving groove does not have an inner wall close to the lower position. In fact, the limiting receiving groove does not have to appear in the form of a groove. As long as there is an area between the upper object 3 and the lower object 4 that can accommodate the limiting part 232 in the locked state.

[0051] Preferably, the rotatable connection between the rotary knob 23 and the slide switch 22 is located below the force-receiving part 231, and the limiting part 232 and the force-receiving part 231 on the rotary knob 23 are located on both sides of the rotatable connection between the rotary knob 23 and the slide switch 22. More preferably, the force-receiving part 231 is a force-receiving plate, which tilts from top to bottom in the first direction in the locked state.

[0052] Preferably, the second connecting part 2 includes a rotary knob 23, two locking parts 221 and two compression springs 24; in the direction of the rotation axis of the rotary knob 23 and the slide switch 22, the two locking parts 221 are provided on both sides of the rotary knob 23, and the two compression springs 24 are also provided on both sides of the rotary knob 23.
