[0061] In the description of the present invention, it should be noted that the orientation or positional relationship indicated by the terms "upper", "middle", "lower", "inner", "outer", "front", "rear", etc. is based on the orientation or positional relationship shown in the accompanying drawings. It is only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or component referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation of the present invention. The terms "first", "second", "third" are only used for descriptive purposes and cannot be understood as indicating or implying relative importance. For those of ordinary skill in the art, the specific meanings of the above terms in the present invention can be understood according to specific circumstances. The following will describe its implementation manner according to the overall structure of the present invention.

[0062] Refer to Figure 1 As shown, the embodiment of this application provides a quick-release connection structure, including:

[0063] A supporting part 1, the supporting part 1 has a first end side 11 and a second end side 12;

[0064] A pressing part 2 installed on the first end side 11 of the supporting part 1, and the pressing part 2 can move relative to the supporting part 1;

[0065] A piston part 3 penetrating through the supporting part 1, the piston part 3 penetrates out of the first end side 11 from the second end side 12, and the piston part 3 is fixedly connected to the end side of the pressing part 2 facing the supporting part 1;

[0066] An elastic member 4 is sleeved on the outer wall of the supporting part 1, one end of the elastic member 4 is fixedly installed on the outer wall of the supporting part 1, and the other end of the elastic member 4 is fixedly installed on the inner wall of the pressing part 2;

[0067] Among them, a stop portion 142 and an inclined surface portion 143 are provided near the first end side 11 of the support portion 1, and at least one first blocking rib 211 and at least one second blocking rib 212 are provided on the inner wall of the pressing portion 2; when the first blocking rib 211 abuts against the stop portion 142, the piston portion 3 is stationary; when pressing the pressing portion 2 to separate the first blocking rib 211 from the stop portion 142, the second blocking rib 212 moves along the inclined surface portion 143, so that the piston portion 3 moves to lock or unlock.

[0068] According to Figure 1 , those skilled in the art can set the support portion 1, the pressing portion 2 and the piston portion 3 for installation, and the piston portion can move and rotate within the support portion 1, so as to realize the locking and unlocking of the connection of the piston portion 3.

[0069] Specifically, the support portion 1 has a first end side 11 and a second end side 12. The pressing portion 2 is installed on the first end side 11, and relative rotation and relative movement can be performed between the pressing portion 2 and the support portion 1. The piston portion 3 penetrates into the support portion 1 from the second end side 12, and the piston portion 3 penetrates out of the support portion 1 from the first end side 11. The end portion of the piston portion 3 is fixedly connected to the side wall of the pressing portion 2 facing the support portion 1 after passing through the first end side 11.

[0070] It should be noted that the end portion of the piston portion 3 can be fixedly connected to the pressing portion 2 by riveting or welding, or the piston portion 2 and the side wall of the pressing portion 2 facing the support portion 1 are of an integral structure.

[0071] With the above structure, the end portion of the piston portion 3 is fixedly connected to the side wall of the pressing portion 2 facing the support portion 1 after passing through the first end side 11. During the process of pressing the pressing portion 2 to move, the piston portion 3 can move along with the pressing portion 2.

[0072] Furthermore, an elastic member 4 is sleeved on the outer wall of the support portion 1, and both ends of the elastic member 4 are respectively installed on the inner wall of the pressing portion 2 and the outer wall of the support portion 1, so that the pressing portion 4 can be kept stable in relative position without external force through the elastic member 4.

[0073] Even further, those skilled in the art can set a stop portion 142 and an inclined surface portion 143 near the first end side 11 of the support portion 1, and at least one first blocking rib 211 and at least one second blocking rib 212 are provided on the inner wall of the pressing portion 2.

[0074] Specifically, a stop portion 142 and an inclined surface portion 143 are fixedly connected to the outer wall of the support portion 1 near the first end side 11, and a first blocking rib 211 and a second blocking rib 212 are provided on the inner wall of the pressing portion 2. During the connection and movement process, when the first blocking rib 211 abuts against the stop portion 142, the piston portion 3 is stationary; when the pressing portion 2 is pressed to separate the first blocking rib 211 from the stop portion 142, the second blocking rib 212 moves along the inclined surface portion 143, causing the piston portion 3 to move and be locked or unlocked.

[0075] That is, in the initial position, the first blocking rib 211 abuts against the stop portion 142, so that the pressing portion 2 cannot rotate and can only move. At the same time, the piston portion 3 fixedly connected to the pressing portion 2 also cannot rotate. A person skilled in the art can press the pressing portion 2 so that the pressing portion 2 moves in the direction of the support portion 1, so that the piston portion 3 can also move synchronously. When the pressing is moved until the first blocking rib 211 is separated from the stop portion 142, the pressing portion 2 can rotate. During the rotation of the pressing portion 2, the second blocking rib 212 moves along the inclined surface portion 143.

[0076] Through the above process, a person skilled in the art can make the pressing portion 2 enter the locked state after rotation. When the pressing portion 2 is further pressed, under the action of the elastic portion 4, the pressing portion 2 rotates in the opposite direction, so that the second blocking rib moves along the inclined surface portion 143 to the original position.

[0077] In a specific implementation, when the pressing portion 2 is in the initial position, a person skilled in the art presses the pressing portion 2 so that the first blocking rib 211 is separated from the stop portion 142, and the second blocking rib 212 moves along the inclined surface portion 142, causing the pressing portion 2 to rotate 90 degrees clockwise and then the first blocking rib 211 abuts against the stop portion 142. That is, the pressing portion 2 is locked. Subsequently, a person skilled in the art can press the pressing portion 2 again to separate the first blocking rib 211 from the stop portion 142, and the second blocking rib 212 moves along the inclined surface portion 142, causing the pressing portion 2 to rotate 90 degrees counterclockwise and then the first blocking rib 211 abuts against the stop portion 142. That is, the pressing portion 2 is unlocked.

[0078] In an alternative embodiment, preferably, two first blocking ribs 211 and one second blocking rib 212 are provided on the inner wall of the support portion 1, and two stop portions 142 are provided near the first end side of the support portion 1, and the two first blocking ribs 211 respectively correspond to the two stop portions 142 one by one.

[0079] Specifically, those skilled in the art set one second blocking rib 212 fixedly installed between two first blocking ribs 211. Among them, the two first blocking ribs 211 and the one second blocking rib 212 are arranged at intervals. At the same time, those skilled in the art can set two stop portions 142 near the first end side of the support portion 1, and the two first blocking ribs 211 respectively correspond to the two stop portions 142 one by one.

[0080] With the above structure, during the process of pressing and moving the pressing portion 2, the two first blocking ribs 211 are respectively separated from the two stop portions 142. During the process of the pressing portion 2 rotating, the second blocking rib 212 moves along the surface of the inclined surface portion 143. When the two first blocking ribs 211 respectively abut against the adjacent stop portions 142, the rotation process ends.

[0081] During the above process, the piston portion 3 can be locked. When those skilled in the art need to unlock, they can press the pressing portion 2, so that the pressing portion 2 drives the piston portion 3 to move reversely along the original trajectory under the action of the elastic member 4.

[0082] In an alternative embodiment, those skilled in the art can relatively arrange the two stop portions 142 on the first end side 11 of the support portion 1, and the connection line of the two stop portions 142 passes through the center of the first end side 11 of the support portion 1.

[0083] In the above embodiments, the stop portion 142 can be set in an "ear shape" with straight sides on both sides and a curved side away from the first end side 11.

[0084] In the above embodiment, those skilled in the art set the elastic member 4 to be sleeved on the outer wall of the support portion 1, and the two ends of the elastic member 4 are respectively connected to the pressing portion 2 and the support portion 1. Preferably, a receiving groove 213 is formed on the inner wall of the pressing portion 2, and a sliding groove 141 is formed on the outer wall of the support portion 1. The receiving groove 213 and the sliding groove 141 respectively accommodate the two ends of the elastic member 4.

[0085] With the above structure, those skilled in the art can set the two ends of the elastic member 4 to be respectively in the receiving groove 213 on the pressing portion 2 and the sliding groove 141 on the support portion 1, which can make the elastic member 4 more stable during the compression and recovery process.

[0086] More preferably, the elastic member 4 is a torsion spring. One end of the torsion spring is provided with a first mounting end 41 extending in a direction away from the support portion 1, and the first mounting end 41 passes through the receiving groove 213. The other end of the torsion spring is provided with a second mounting end 42 extending in a direction close to the support portion 1, and the second mounting end 42 passes through the sliding groove 141.

[0087] With the above structure, those skilled in the art can set the torsion spring so that the torsion spring can be distorted when the pressing part 2 rotates and locks. Further, during the second pressing of the pressing part 2 by those skilled in the art, the torsion spring automatically restores its deformation, so that the pressing part 2 can be unlocked in the reverse direction along the original trajectory.

[0088] It can be understood that when the elastic member 4 is set as a torsion spring, the torsion spring can continue to be provided with a first mounting end 41 and a second mounting end 42. In the above embodiment, those skilled in the art can set the torsion spring sleeved on the outer wall of the support part 1, and the first mounting end 41 of the torsion spring extends in the direction away from the position where the support part 1 is located, so that the first mounting end 41 can be accommodated in the accommodation groove 213. Further, those skilled in the art can set the second mounting end 42 of the torsion spring to extend in the direction close to the position where the support part 1 is located, so that the second mounting end 42 extends into the sliding groove 141.

[0089] With the above structure, the cooperation between the first mounting end 41 and the accommodation groove 213 and the cooperation between the second mounting end 42 and the sliding groove 141 can make the relative position of the elastic member 4 more stable.

[0090] In the above embodiment, those skilled in the art set the pressing part 2 and the piston part 3 to be fixedly connected. Preferably, the pressing part 2 includes a knob 21 and a cap 22. The cap 22 is fixedly installed in the middle position of the knob 21, and the piston part 3 is fixedly connected to the cap 22.

[0091] That is, those skilled in the art can set the pressing part 2 to include a knob 21 and a cap 22. Among them, the cap 22 is fixedly connected to the middle position of the knob 21, and the piston part 3 is fixedly connected to the side wall of the cap 22 facing the inner cavity of the knob 21.

[0092] With the above structure, those skilled in the art can facilitate the installation of the piston part 3 and the support part 1, and continue to install the piston part 3 with the cap 22 after the installation of the piston part 3 is completed, so that the installation structure of the pressing part 2 and the piston part 3 is more stable.

[0093] More preferably, the cross-section of the cap 22 is a water droplet shape with one side protruding. That is, those skilled in the art can judge the rotation angle of the cap 22 according to the protruding part, so as to determine the unlocked and locked states.

[0094] In the structure where the pressing part 2 includes a cap 22 and a knob 21 connected to each other, preferably, the accommodation groove 213, at least one first blocking rib 211 and at least one second blocking rib 212 are all arranged on the side of the cap 22 facing the support part 1, and the accommodation groove 213, at least one first blocking rib 211 and at least one second blocking rib 212 all extend in the direction away from the support part 1.

[0095] In the above structure, those skilled in the art can set the receiving groove 213, the first blocking rib 211, and the second blocking rib 212 on the side of the cap 22 facing the support portion 1, so that the first blocking rib 211, the second blocking rib 212, the stopping portion 142, and the inclined surface portion 143 can be stably matched.

[0096] In an optional preferred manner, the knob 21 is made of plastic, and vertical stripes are provided on the outer wall of the knob 21. It should be noted that those skilled in the art can set the cap 22 to be made of metal and the knob 21 to be made of plastic, so that the structure of the pressing portion 2 is more stable.

[0097] In the above structure, a piston portion 3 is disposed through the support portion 1, and an elastic member 4 is sleeved on the outer wall of the support portion 1. Preferably, the support portion 1 includes a support frame 13 and a sleeve 14, and the sleeve 14 is sleeved on the outer wall of the support frame 13.

[0098] Those skilled in the art set the support portion 1 to be composed of the sleeve 14 sleeved on the outer wall of the support frame 13. The piston portion 3 is disposed through the support frame 13, and the stopping portion 142 and the inclined surface portion 143 are disposed on the outer wall of the sleeve.

[0099] With the above structure, the piston portion 3 is disposed through the support frame 13, and the stopping portion 142 and the inclined surface portion 143 are disposed on the outer wall of the sleeve, which can make the connection between the support portion 1 and the piston portion 3 and the pressing portion 2 more stable.

[0100] More preferably, the sleeve 14 and the support frame 13 are in interference connection, so that the sleeve 14 can be more stable after being sleeved on the support frame 13, and the structural stability of the support portion 1 is significantly improved.

[0101] In the setting of the support frame 13, the support frame 13 includes a rod portion 131 and a bottom portion 132. The rod portion 131 is fixedly connected to the side wall of the bottom portion 132. The sleeve 14 is sleeved on the outer wall of the rod portion 131, and the sleeve 14 is in contact with the bottom portion 132. The elastic member 4 abuts against the bottom portion 142.

[0102] With the above structure, those skilled in the art can set the sleeve 14 to be sleeved on the outer wall of the rod portion 131, and the sleeve 14 is in contact with the bottom portion 132, so that the relative position of the sleeve 14 can be positioned. At the same time, the elastic member 4 abuts against the bottom portion 142, so that the elastic member 4 can be more stable during the compression process.

[0103] Preferably, the outer diameter of the bottom portion 142 is larger than the outer diameter of the pressing portion 2, so that the pressing portion 2 can abut against the side wall of the bottom portion 142 facing the pressing portion 2 in the extreme case of pressing. The above setting can make the relative structure between the pressing portion 2 and the support portion 1 more stable.

[0104] According to the above structure, those skilled in the art set a chute 141 on the outer wall of the support portion 1, and the second mounting end 42 of the torsion spring extends in the direction close to the position where the support portion 1 is located, so that the second mounting end 42 can extend into the chute 141. Preferably, the chute 141 extends axially along the sleeve 14 and penetrates, and stabilizing blocks 144 are fixedly connected to both sides of the end portion of the chute 141 close to the bottom, for restricting the movement of the elastic member 4.

[0105] By means of the above structure, the relative position of the elastic member 4 can be more stable during the sliding process in the chute 141 through the stabilizing blocks 144 fixedly connected to both sides of the end portion of the chute 141 close to the bottom.

[0108] Further, a pressing portion is fixedly connected to one end of the piston portion 3 away from the pressing portion 2. Those skilled in the art press the piston portion 3, so that the first blocking rib 211 is separated from the stopping portion 142, and the second blocking rib 212 moves along the inclined surface portion 142, so that after the pressing portion 2 rotates clockwise by 90 degrees, the first blocking rib 211 abuts against the stopping portion 142. During the above process, the piston portion 2 moves through the second board 6. After the pressing portion 2 rotates clockwise by 90 degrees, the first blocking rib 211 abuts against the stopping portion 142, so that the pressing portion on the piston portion 2 abuts against the wall surface of the second board 6 away from the first board 5 after passing through the second board 6.

[0109] By means of the above process, the locking of the second board 6 can be completed by driving the movement and rotation of the piston portion 3 by the pressing portion 2. According to another embodiment in this specification, a force can be continuously applied to the pressing portion 2, so that the piston portion 3 is reset, and thus the unlocking of the second board 6 can be completed.

[0110] In summary, the first plate 5 can be fixedly connected through the supporting portion 1, and at the same time, the second plate 6 can be locked and unlocked through the piston portion 3, the supporting portion 1, and the pressing portion 2, so that the connection and unlocking of the two plates can be completed.

[0111] Preferably, the first plate 5 and the second plate 6 are parallel to each other, so that the above-mentioned connecting member can connect two parallel plates.
