[0040] Please see Figure 1 and Figure 2 As shown, this utility model is a quick-release mechanism for a connecting hub on an infant rocker, including a lower housing 1, a quick-release component, and an unlocking mechanism 4. The quick-release component is disposed above the lower housing 1; the unlocking mechanism 4 is disposed on the lower housing 1, and the quick-release component is locked or unlocked to the lower housing 1 by means of the unlocking mechanism 4.

[0041] During use, the lower housing 1 of this application can be connected to the base frame on the baby rocker. The disassembly component is located between the base frame and the rocker frame on the baby rocker. During the quick-release operation, the operator can remove the quick-release component from the lower housing 1 through the unlocking mechanism 4, so that the rocker frame can be removed from the base frame when not in use, reducing the floor space occupied and thus improving the convenience when carrying it out. In addition, disassembly facilitates the replacement and maintenance of the components of the connecting hub. This application has a simple structure and is easy to operate and use.

[0042] In this specific implementation, such as Figures 3 to 7 As shown, the quick-release assembly includes an upper housing 2, a bracket 3, an upper snap cover 5, and a lower snap cover 6 arranged in layers from top to bottom. The upper housing 2, bracket 3, upper snap cover 5, and lower snap cover 6 are connected by a coaxial mechanism. The coaxial mechanism can ensure the coaxiality installation accuracy between the upper housing 2, bracket 3, upper snap cover 5, and lower snap cover 6. After the quick-release assembly is disassembled, the upper housing 2, bracket 3, upper snap cover 5, and lower snap cover 6 can be disassembled in sequence, making the operation convenient.

[0043] In this specific embodiment, the coaxial mechanism includes an inner positioning post 21, a locking post 22, and a ring locking block 24. The inner positioning post 21 is integrally set at the center of the upper housing 2. The inner positioning post 21 is inserted and connected to the upper snap cover 5 and the lower snap cover 6. The T-shaped locking post 22 is threadedly connected to the central threaded hole of the inner positioning post 21. A locking groove 23 is formed between the T-head end of the locking post 22 and the top end of the inner positioning post 21. The ring locking block 24 is threadedly connected to the outer wall of the inner positioning post 21. The lower snap cover 6, the upper snap cover 5, and the bracket 3 are limited and installed on the upper housing 2 by the ring locking block 24.

[0044] The coaxial mechanism also includes an outer positioning post 20, which is integrally set on the upper housing 2. The diameter of the outer positioning post 20 is larger than that of the inner positioning post 21. The upper housing 2 is connected to a bracket 3 by a snap fastener, and the outer positioning post 20 is inserted into the bracket 3. The upper snap fastener cover 5 is set on the port surface of the upper housing 2 and is used to abut against the bracket 3. The lower snap fastener cover 6 is set on the port surface of the lower housing 1 and is used to abut against the upper snap fastener cover 5.

[0045] When using the coaxial mechanism, the bracket 3 is pre-attached to the upper housing 2. The bracket 3 is positioned and installed by the outer positioning post 20, which is convenient for installation. Then, the upper snap cover 5 and the lower snap cover 6 are installed in sequence along the inner positioning post 21. Finally, the lower snap cover 6, the upper snap cover 5 and the bracket 3 are limited and installed on the upper housing 2 by the ring block on the inner positioning post 21, which can ensure the installation accuracy of the quick-release assembly. When the quick-release assembly is removed from the lower housing 1, it is disassembled in sequence. In addition, the locking groove 23 formed between the inner positioning post 21 and the locking post 22 facilitates locking by the unlocking mechanism 4.

[0046] In this specific implementation, such as Figures 8 to 11 As shown, the unlocking mechanism 4 includes an unlocking button 40, a connecting plate 41, and an unlocking plate 42 connected in an integral structure. The unlocking plate 42 has a strip-shaped unlocking hole. One end of the unlocking hole is a locking part 420, and the other end is an unlocking part 421. The hole diameter width decreases from the unlocking part 421 to the locking part 420. The integrated unlocking button 40, connecting plate 41, and unlocking plate 42 can move synchronously, thereby locking or unlocking the quick-release assembly to the lower housing 1 through the unlocking mechanism 4.

[0047] When the quick-release assembly is locked to the lower housing 1 by the unlocking mechanism 4, one end of the return spring 43 of the unlocking mechanism 4 abuts against the spring abutment 102 inside the lower housing 1, and the other end abuts against the tail end of the unlocking plate 42. The return spring 43 is used to press the unlocking button 40 into the button socket 100 on the lower housing 1, and the locking part 420 is snapped into the lock groove 23. When the lock is installed and used, the return spring 43 presses the unlocking plate 42, the connecting plate 41 and the unlocking button 40 to move under its own elastic force, so that the unlocking button 40 can be easily inserted into the button socket 100 on the lower housing 1 for locking. At this time, the locking part 420 at one end of the unlocking hole reaches the connection position with the lock groove 23, so that the unlocking plate 42 can be snapped between the lock post 22 and the inner positioning post 21, so that the lower housing 1 and the quick-release assembly are locked and connected.

[0048] When the quick-release assembly is unlocked and locked to the lower housing 1 by the unlocking mechanism 4, the unlocking button 40 presses and compresses the return spring 43, and the locking pin 22 moves to the unlocking part 421 position. The width of the unlocking part 421 is greater than the diameter of the head end of the locking pin 22T. When using the quick-release mechanism, the user can press the unlocking button 40, and the unlocking button 40 retracts into the lower housing 1 along the button socket 100. At this time, the unlocking part 421 at one end of the unlocking hole moves to the locking pin 22 position. The width of the unlocking part 421 is greater than the diameter of the head end of the locking pin 22T, so that the locking pin 22 can be pulled out from the unlocking part 421 position to complete the overall removal of the quick-release assembly.

[0049] During the movement of the unlocking mechanism 4, there is a height difference between the locking pin 22 and the unlocking plate 42. To maintain the stability of the overall lateral movement of the unlocking mechanism 4, a stabilizing plate 410 is abutted on the connecting plate 41. One end of the stabilizing plate 410 is vertically connected to the lower insertion pin 411, and the other end is vertically connected to the upper insertion pin 412. The lower insertion pin 411 is used to insert and connect with the stabilizing pin 101 on the lower housing 1, and the upper insertion pin 412 is used to slide along the contour groove formed between the guide block 413 and the guide groove 414. The guide block 413 is set in the guide groove 414, and the guide groove 414 is located on the stabilizing plate 410. During the lateral movement of the unlocking mechanism 4, the lower insertion pin 411 is always inserted and connected with the stabilizing pin 101 on the lower housing 1, and the upper insertion pin 412 slides along the contour groove formed between the guide block 413 and the guide groove 414, thereby ensuring the stability of the overall lateral movement of the unlocking mechanism 4.

[0050] The above description provides a detailed account of one embodiment of the present invention. However, this description is merely a preferred embodiment and should not be construed as limiting the scope of the present invention. All equivalent variations and improvements made within the scope of the claims of the present invention should still fall within the patent coverage of the present invention.
