[0043] As Figures 1-7As shown, the utility model embodiment provides a kind of locking device, for being locked object is installed on the main frame of ice maker. The locking device includes fixed frame 1 and locking assembly 2, wherein, fixed frame 1 is arranged on main frame, and fixed frame 1 includes multiple surrounding rods, multiple surrounding rods are sequentially connected head-to-tail and are surrounded to form through opening 11, being locked object can be limited in through opening 11, at least one surrounding rod is provided with sliding hole 12 communicated with through opening 11. Locking assembly 2 includes turnover buckle 21 and locking rod 22, locking rod 22 is slidably arranged in sliding hole 12, and one end of locking rod 22 is connected with turnover buckle 21;Turnover buckle 21 has locking state and unlocking state, when turnover buckle 21 is in locking state, turnover buckle 21 can make the other end of locking rod 22 extend sliding hole 12 to through opening 11 and lock being locked object, to realize being locked object and the locking of fixed frame 1;When turnover buckle 21 is in unlocking state, turnover buckle 21 can make the other end of locking rod 22 retract to sliding hole 12 and be unlocked with being locked object, to realize being locked object and the unlocking of fixed frame 1.

[0044] The locking device switches between unlocking state and locking state by turnover buckle 21, to make locking rod 22 can extend sliding hole 12 to through opening 11 or retract to sliding hole 12, realizes the quick disassembly and quick locking of being locked object and fixed frame 1;And when locking, being locked object is limited in through opening 11, and being locked object is locked by locking rod 22 extending sliding hole 12 to through opening 11, so that being locked object is fixed firmly, effectively prevent being locked object from falling off, also avoid using screw, improve the appearance.

[0045] Optionally, as Figures 3-4 As shown, locking rod 22 includes main body part 221 and plug-in part 222 arranged at one end of main body part 221, the cross-sectional dimension of plug-in part 222 is greater than the cross-sectional dimension of main body part 221, and the end of main body part 221 away from plug-in part 222 is connected with turnover buckle 21;The inner wall of sliding hole 12 is provided with annular limiting portion 121;The locking device further includes elastic member 23, and elastic member 23 is arranged in sliding hole 12 and elastically abuts between plug-in part 222 and annular limiting portion 121. When turnover buckle 21 is in locking state, plug-in part 222 can be moved towards being locked object and extend sliding hole 12 under the action of elastic member 23, when turnover buckle 21 is in unlocking state, turnover buckle 21 makes locking rod 22 move away from being locked object and retract to sliding hole 12 against the action of elastic member 23, by setting elastic member 23, turnover buckle 21 can be limited in locking state and unlocking state, to prevent turnover buckle 21 from switching between locking state and unlocking state accidentally, and being locked object from falling off accidentally.

[0046] Optionally, elastic member 23 can be selected as spring or multiple superimposed disc springs.

[0047] Optionally, as Figure 5 The turnover buckle 21 includes two spaced side plates 211 and a connecting plate 212 vertically connected between the two side plates 211, a hinge shaft 213 is arranged between the two side plates 211, and one end of the main body 221 of the locking rod 22 is hinged to the hinge shaft 213. When the turnover buckle 21 is in the locked state, the locking rod 22 is vertically distributed with the connecting plate 212, and when the turnover buckle 21 is in the unlocked state, the locking rod 22 is parallelly distributed with the connecting plate 212. This structure realizes that when the turnover buckle 21 switches between the locked state and the unlocked state, the locking rod 22 can realize linear movement, so that the locking rod 22 can extend out of or retract into the sliding hole 12.
