[0022] This utility model embodiment provides a top-press type detachable mechanical self-locking handle, such as Figure 1-4 As shown, the detachable connection and fixing parts have all core load-bearing components made of metal: including a connecting part and a grip part. The upper end face of the fixing part has a locking hole. The connecting part includes a front buckle and a rear buckle. The front buckle connects to the grip part. The front end of the grip part has a cavity, and a top button is vertically slidably installed at the top. An elastic element is provided between the front buckle and the rear buckle. When connected, the front end of the front buckle engages with the locking hole, and the rear buckle, under the elastic action of the elastic element, engages with the buckle on the lower side of the upper end face of the fixing part, thereby achieving connection with the fixing part. When disassembling, press the top button, which drives the rear buckle to slide backward, disengaging the rear buckle from the upper end face of the fixing part. Then, rotate the handle upward to pull it out, disengaging the front buckle from the locking hole and releasing the connection between the handle and the fixing part.
[0023] like Figure 4 As shown, a first inclined block is provided at the upper end of the rear buckle, and a second inclined block is provided at the lower end of the corresponding top button. The second inclined block is in contact with the inclined surface of the first inclined block. When the top button is pressed, the second inclined block drives the first inclined block to move the rear buckle backward. Through this inclined surface structure design, when the side button is pressed, the guiding effect of the inclined surface can be used to drive the rear buckle to slide more smoothly, ensuring the convenience of disassembly operation.
[0024] Preferably, the front buckle has a through groove, the first inclined block passes through the through hole and contacts the inclined surface of the second inclined block, and the through groove has a margin for the first inclined block to slide horizontally, and the elastic element is disposed between the rear side of the first inclined block and the inner wall of the rear side of the through groove.
[0025] Preferably, the grip portion is formed by an upper shell and a lower shell respectively wrapping around the front buckle, and the length of the front buckle is greater than the length of the upper shell and the lower shell. For example... Figure 1 and Figure 2 As shown, the grip is formed by an upper shell and a lower shell respectively wrapping around the front buckle. The upper shell and the lower shell are fixed together by bolts. The length of the front buckle is greater than the length of the upper shell and the lower shell. This structural design facilitates the assembly of the grip and the front buckle. At the same time, the longer front buckle provides a more stable connection base.
[0026] like Figure 2As shown, the front buckle has a hanging hole at its rear end for easy storage: the hanging hole at the rear end of the front buckle facilitates the hanging and storage of the handle, saving space and making it easy to manage.
[0027] like Figure 2 and 3 As shown, a limiting block is provided on the lower side of the top button, and a limiting groove is provided in the cavity of the corresponding upper shell. The limiting block slides within the limiting groove. The cooperation between the limiting block and the limiting groove can limit the sliding range of the side button, prevent the side button from detaching from the cavity of the hand grip during sliding, and ensure the normal use of the side button.
[0028] Preferably, the front end of the lower shell is provided with a horizontal groove, and the rear buckle is slidably connected in the groove.
[0029] Working principle: One end of the fixed part is connected to the cookware. When connecting the top-press detachable mechanical self-locking handle of this utility model to the fixed part, first align the front end of the front buckle with the locking hole at an angle and press the top button. During the pressing process, the top button drives the inclined block two to slide against the inclined surface of the inclined block one. The rear buckle is driven by the button and overcomes the elastic force of the elastic element to move backward in the slide groove. When the handle is in a horizontal position with the fixed part, release the top button. Under the elastic action of the elastic element, the rear buckle returns to its original position, moves forward, and locks into the lower end face of the fixed part. At this time, the front end of the front buckle also locks into the locking hole, completing the connection between the handle and the fixed part. The connection is stable and reliable.
[0030] When you need to remove the handle, press the top button with your finger. Since the inclined block one of the rear latch is slidably connected to the inclined block two of the top button, the top button drives the rear latch to slide backward during the pressing process. The rear latch gradually disengages from the rear fixing part. When the rear latch is completely disengaged from the rear fixing part, turn the handle and pull it backward to disengage the front latch from the locking hole, thereby removing the handle from the fixing part. The operation is simple and convenient.
[0031] In summary, the top-press detachable mechanical self-locking handle of this utility model, through its unique structural design, achieves simple operation, stable connection, and reasonable storage, and has high practical value and market promotion prospects.
[0032] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
