[0030] Example:

[0031] Please see Figure 1-4 A quick-assembly and disassembly universal ball joint includes a ball base 1, a cavity 2 at the top of the ball base 1, a main ball 3 rotatably connected within the cavity 2, an end cap 4 fixedly connected within the cavity 2, and the main ball 3 movably passing through the end cap 4. Two mounting grooves 5 are formed on the outer surface of the ball base 1, and a bottom groove 6 is formed at the bottom end of the ball base 1, communicating with the two mounting grooves 5. Buttons 7 are slidably connected within the two mounting grooves 5, with the ends of the two buttons 7 approaching each other extending into the bottom groove 6. A compression spring is fitted onto the outer surface of each of the two buttons 7. Spring 8, and two compression springs 8 are respectively located in two mounting slots 5. A limit block 9 is fixedly connected to the outer surface of the ball seat 1, and the ends of the two buttons 7 that are far apart both extend to the outside of the limit block 9. A connecting seat 11 is fixedly connected to the bottom end of the ball seat 1, and a cover 12 is fixedly connected to the bottom end of the connecting seat 11. A limit block 13 is provided in the connecting seat 11, and the top end of the limit block 13 extends into the bottom groove 6 and corresponds to the two buttons 7. A lifting spring 14 is provided between the bottom of the limit block 13 and the bottom wall of the cover 12.

[0032] In this embodiment, the main ball 3 is placed inside the cavity 2 at the top of the ball seat 1. The end cap 4 is fixed inside the cavity 2 to restrict the main ball 3, allowing the main ball 3 to roll stably on the top of the ball seat 1 for product transport. Compression springs 8 are respectively fitted onto the outer surfaces of the two buttons 7. The two buttons 7, each with its own compression spring 8, are inserted into the two mounting slots 5. The ends of the two buttons 7 that are close together extend into the bottom groove 6. By fixing the limiting block 9 to the outer surface of the ball seat 1, the limiting block 9 restricts the two buttons 7, ensuring that the two buttons 7 are stably positioned within the two mounting slots 5. The limiting block 13 is slidably installed inside the connecting seat 11, with its top extending into the bottom groove 6 corresponding to the two buttons 7. The bottom of the limiting block 13 is connected to one end of the lifting spring 14. The cover 12 seals the bottom of the connecting seat 11, ensuring that the limiting block 13 and the lifting spring 14 are stably installed within the connecting seat 11. When the universal ball is installed on the conveyor table, pressing the two buttons 7 causes the two buttons 7 to move in opposite directions. The two mounting slots 5 slide and compress the two compression springs 8. At the same time, the two buttons 7 contact the top of the limiting block 13 and press it downward. The limiting block 13 moves down and presses the lifting spring 14. During the downward movement, it contacts the cover 12 and retracts inward. By inserting the cover 12 into the mounting hole on the conveyor table, the bottom end of the limiting block 9 contacts the top end of the conveyor table. Then, the pressure on the two buttons 7 is released. The two compression springs 8 move the two buttons 7 away from the reset position. The lifting spring 14 raises the limiting block 13 to the reset position. After the limiting block 13 is reset, it unfolds and is located on the lower side of the conveyor table. The limiting block 13 and the limiting block 9 cooperate to restrict the ball seat 1 on the conveyor table. The main ball 3 rolls and transports the product. When the universal ball needs to be removed from the conveyor table for maintenance, the two buttons 7 are pressed to make the limiting block 13 move down and retract again, releasing the limitation of the limiting block 13 on the conveyor table. This allows the ball seat 1 to be pulled out of the conveyor table and removed, realizing the disassembly of the universal ball.

[0033] Specifically, the cavity 2 includes an annular cavity 21 and an arc-shaped cavity 22, which are sequentially opened from top to bottom at the top of the ball seat 1. The main ball 3 is rolled and connected in the arc-shaped cavity 22, and the end cap 4 is fixedly connected in the annular cavity 21.

[0034] In this embodiment, the cavity 2 is composed of an annular cavity 21 and an arc-shaped cavity 22. The main ball 3 is placed in the arc-shaped cavity 22, and the end cap 4 is installed in the annular cavity 21 to restrict the main ball 3, so that the main ball 3 can roll stably in the arc-shaped cavity 22 to transport the product.

[0035] Specifically, each button 7 includes a pressing post 71 and a limiting protrusion 72. The pressing post 71 is slidably inserted into a mounting groove 5, and one end of the pressing post 71 extends into the bottom groove 6. The limiting protrusion 72 is fixedly connected to the outer surface of the pressing post 71, and a compression spring 8 is sleeved on the outer surface of the pressing post 71 and corresponds to the limiting protrusion 72.

[0036] In this embodiment, pressing the two pressing posts 71 can push the limiting block 13 down, realizing the assembly and disassembly of the universal ball on the conveyor table. The two limiting protrusions 72 correspond to the two compression springs 8 respectively, so that the two pressing posts 71 can squeeze the two compression springs 8 when pressed, which facilitates the two compression springs 8 to reset the two pressing posts 71. In addition, the two limiting protrusions 72 correspond to the limiting block 9. The limiting block 9 can restrict the two pressing posts 71 through the two limiting protrusions 72, preventing the two pressing posts 71 from detaching from the two mounting slots 5.

[0037] Specifically, the limiting block 9 includes an annular sleeve 91 and two limiting ports 92. The annular sleeve 91 is fixedly connected to the outer surface of the ball seat 1. The two limiting ports 92 are both opened on the annular sleeve 91, and the ends of the two pressing posts 71 that are far apart pass through the two limiting ports 92 respectively.

[0038] In this embodiment, the annular sleeve 91 is fixed to the outer surface of the ball seat 1. The two pressing posts 71 pass through the annular sleeve 91 through the two limiting holes 92, so that the ends that are far apart pass through to the outside for easy pressing. The diameter of the two limiting protrusions 72 is greater than the width of the two limiting holes 92, so that the annular sleeve 91 can limit the penetration distance of the two pressing posts 71 and prevent the two pressing posts 71 from falling off.

[0039] Specifically, the connecting seat 11 includes a connecting cylinder 111 and multiple sliding grooves 112. The connecting cylinder 111 is fixedly connected to the bottom end of the ball seat 1. The multiple sliding grooves 112 are all opened on the connecting cylinder 111 and are distributed at equal intervals. The limiting block 13 is slidably connected in the multiple sliding grooves 112.

[0040] In this embodiment, the limiting block 13 is slidably connected to the connecting cylinder 111 and multiple sliding grooves 112. The limiting block 13 is in the unfolded state in the initial position. It extends through multiple sliding grooves 112 to the outside of the connecting cylinder 111, which can restrict the universal ball on the conveyor table. When the limiting block 13 is pressed down, it will contact the cover 12, causing the part that extends through multiple sliding grooves 112 to retract inward, which can remove the restriction on the conveyor table and realize the removal of the universal ball.

[0041] Specifically, the cover 12 includes a bottom cover 121 and multiple plates 122. The bottom cover 121 is fixedly connected to the bottom of the connecting cylinder 111. The multiple plates 122 are all fixedly connected to the top of the bottom cover 121 and are distributed at equal intervals. The multiple plates 122 are respectively inserted into multiple sliding grooves 112 and correspond to the limiting block 13.

[0042] In this embodiment, the bottom cover 121 is fixed to the bottom of the connecting cylinder 111, which restricts the limiting block 13 and the lifting spring 14 within the connecting seat 11. Multiple plates 122 are located in multiple sliding grooves 112 and correspond to the limiting block 13. When the limiting block 13 moves down, it will contact multiple plates 122 to retract, which facilitates the assembly and disassembly of the universal ball on the conveyor table.

[0043] Specifically, the limiting block 13 includes a top post 131, a base 132, and multiple posts 133. The top post 131 is slidably inserted into the bottom groove 6, and the posts 133 correspond to the two pressing posts 71. The base 132 is fixedly connected to the bottom of the top post 131 and is slidably connected to the connecting cylinder 111. The multiple posts 133 are all fixedly connected to the base 132 and are equidistantly distributed. The multiple posts 133 are slidably connected to multiple grooves 112 and correspond to multiple plates 122.

[0044] In this embodiment, when the two pressing columns 71 are pressed, they squeeze the top of the top column 131 and cause it to move downward. The top column 131 drives the card seat 132 to slide downward in the connecting cylinder 111 within the bottom groove 6. The downward movement of the card seat 132 causes multiple card columns 133 to slide downward in multiple sliding grooves 112 and contact multiple plates 122. The multiple plates 122 cause the downward-moving multiple card columns 133 to retract into the connecting cylinder 111, which facilitates the quick assembly and disassembly of the universal ball on the conveyor table.

[0045] Specifically, a positioning groove 10 is provided at the bottom end of the top column 131, and the top end of the lifting spring 14 is fixedly connected to the positioning groove 10.

[0046] In this embodiment, the positioning groove 10 is used to position the lifting spring 14, so that the elastic force of the lifting spring 14 can act stably on the limiting block 13.

[0047] Specifically, a secondary ball 15 is provided inside the arc-shaped cavity 22, and the secondary ball 15 is in contact with the outer surface of the main ball 3.

[0048] In this embodiment, the secondary ball 15 is placed before the main ball 3 is placed into the arc-shaped cavity 22. The secondary ball 15 is located between the inner wall of the arc-shaped cavity 22 and the outer surface of the main ball 3, which can reduce the friction of the main ball 3 when it rolls in the arc-shaped cavity 22 and improve the rolling and conveying effect of the product.

[0049] Specifically, the outer surface of the ball seat 1 is provided with a first assembly groove 16, and the annular sleeve 91 is fixedly connected to the first assembly groove 16. The bottom of the connecting cylinder 111 is provided with a second assembly groove 17, and the bottom cover 121 is fixedly connected to the second assembly groove 17.

[0050] In this embodiment, the first assembly groove 16 is used to position the annular sleeve 91, which facilitates the installation of the annular sleeve 91 on the outer surface of the ball seat 1, and the second assembly groove 17 is used to position the bottom cover 121, which facilitates the installation of the bottom cover 121 on the bottom of the connecting cylinder 111.

[0051] Working principle: When installing the omnidirectional ball on the conveyor table, pressing the two pressing posts 71 causes them to slide within the two limiting ports 92. The two pressing posts 71 drive the two limiting protrusions 72 to compress the two compression springs 8 within the two mounting grooves 5. Simultaneously, the two pressing posts 71 press downwards on the top of the top post 131, causing the top post 131 to compress the lifting spring 14 through the bottom cover 121. During the downward pressure of the top post 131, the locking seat 132 slides downwards within the connecting cylinder 111. The locking seat 132 then drives multiple locking posts 133 to move downwards within multiple sliding grooves 112. During this downward movement, the multiple locking posts 133 contact multiple plates 122, causing the multiple plates 122 to retract the multiple locking posts 133 into the connecting cylinder 111. This retraction is achieved by the bottom cover 121 corresponding to the mounting holes on the conveyor table. Insert the ring sleeve 91 so that the bottom end contacts the top of the conveyor table. Then release the two pressing pins 71. The two compression springs 8 elastically reset the two pressing pins 71 through the two limiting protrusions 72. The lifting spring 14 elastically resets the top pin 131. The top pin 131 drives multiple pins 133 to move upward in multiple slide grooves 112 through the pin seat 132. After the multiple pins 133 move upward, they cancel contact with multiple plates 122, thus unfolding at the bottom of the conveyor table, allowing the ball seat 1 to be installed on the conveyor table. The main ball 3 rolls and conveys the product. When the universal ball needs to be removed from the conveyor table for maintenance, press the two pressing pins 71 again to move the four pins 133 downward into the connecting cylinder 111 and retract, thereby canceling the restriction on the conveyor table and allowing the ball seat 1 to be pulled out and disassembled from the conveyor table.

[0052] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model based on the technical solution and its improved concept should be covered within the protection scope of the present utility model.
