Detailed Description

The principles and features of the present invention are described below in conjunction with the following drawings, the examples given are only intended to illustrate the present invention and are not intended to limit the scope of the present invention. The invention is described in more detail in the following paragraphs by way of example with reference to the accompanying drawings. The advantages and features of the present invention will become more fully apparent from the following description and appended claims. It should be noted that the drawings are in simplified form and are not to precise scale, and are provided for convenience and clarity in order to facilitate the description of the embodiments of the present invention.

Referring to fig. 1 to 5, a detachable lock mechanism includes an unlocking button 1, a button compression spring 3, a transmission rod 7, a stop lock rod 9, a cam locking block 10, a locking block torsion spring 11, a locking block rotating shaft 12, and a fixing seat 13, wherein the button compression spring 3 can be directly sleeved on the unlocking button 1, or a button framework 2 is sleeved on the unlocking button 1, the button compression spring 3 is sleeved on the button framework 2, and the button framework 2 is arranged on a button installation framework 4;

the unlocking button 1 (or the button framework 2) and the transmission rod 7 are in inclined surface transmission, namely contact surfaces of the unlocking button 1 (or the button framework 2) and the transmission rod 7 are all arranged into inclined surfaces, when a horizontal force is applied to the unlocking button 1 (or the button framework 2), a vertical force is generated through inclined surface transmission to push the transmission rod 7, the transmission rod 7 is sleeved with a transmission rod pressure spring 71, a stop lock rod 9 is arranged below the transmission rod 7, a lock rod pressure spring 91 is sleeved on the stop lock rod 9, a cam locking block 10 is arranged on one side of the stop lock rod 9, the cam locking block 10 is arranged on a fixed seat 13 through a locking block rotating shaft 12, a locking block torsion spring 11 is arranged on the cam locking block 10, the stop lock rod 9 abuts against the cam locking block 10, and a lock hook 101 of the cam locking block 10 is clamped in a lock hole. A buffer block 8 is arranged between the transmission rod 7 and the stop lock rod 9, and the buffer force is started between the transmission rod 7 and the stop lock rod 9.

As shown in fig. 6-1 to 6-3, at this time, the vehicle-mounted refrigerator 20 is connected with the cladding framework 21 of the central channel on the automobile, the whole lock mechanism is connected with the cladding framework 21 through the lock mechanism upper support 5 and the lock mechanism lower support 6, the refrigerator and the cladding framework are locked and fixed by the lock mechanism, the refrigerator and the cladding framework are precisely close to each other without a gap, and the lock hook 101 of the cam locking block 10 is clamped in the lock hole of the refrigerator.
