[0041] Step 1.3, conversion from handle retracted locked state to handle extended state:

[0042] When the shrink assembly (100) is in the handle shrink locking state, the operating handle (101) is pushed forward, the operating handle (101) gives the push force to the forward movement of the guide rod (106), the second stretch compression spring (107) has the upward push force to the guide rod (106), the resultant force makes the top end of the guide rod (106) slide from the fourth position point to the fifth position point, at this time, the operating handle (101) moves to the deepest position, the first compression spring (103) is in the stretch state, at this time, the push force to the operating handle (101) is removed, the operating handle (101) starts to move backward to the handle extension position under the pull force of the first compression spring (103), at the same time, the pull force to the backward movement of the guide rod (106) is given, the second stretch compression spring (107) has the upward push force to the guide rod (106), the resultant force makes the top end of the guide rod (106) slide along the convex arc-shaped guide rail from the fifth position point back to the first position point, the operating handle (101) is in the extension state, the operating handle (101) can be operated, at this time, the shrink assembly (100) is in the handle extension state.

[0078] The application further provides a method for quickly locking the device, which comprises the following steps:

[0079] Step 1, the contraction assembly 100 has a handle extended state and a handle retracted and locked state; the handle extended state and the handle retracted and locked state of the contraction assembly 100 are converted by pressing the operation handle 101;

[0080] In step 1, the contraction assembly 100 is converted between the handle extended state and the handle retracted and locked state, and the specific method is as follows:

[0081] Step 1.1, the handle extended state:

[0082] When the contraction assembly 100 is in the handle extended state, at this time, the top end of the guide rod 106 slides to the first position point of the special-shaped guide rail 2011, and the second tensile compression spring 107 is in a tensile state; since the first compression spring 103 is in a compressed state, a pushing force in the extended direction is provided to the operation handle 101, so as to maintain the handle extended state;

[0083] Step 1.2, conversion from the handle extended state to the handle retracted and locked state:

[0084] The operation handle 101 is pushed forward, and the whole formed by the operation handle 101, the sliding frame body 102 and the fixed shaft sleeve 105 moves forward, and the fixed shaft sleeve 105 drives the guide rod 106 to move forward.

[0085] When the guide rod 106 moves forward, because the top end of the guide rod 106 is embedded in the special-shaped guide rail 2011, the top end of the guide rod 106 slides along the concave band inflection point arc-shaped guide rail from the first position point to the second position point, so that the guide rod 106 moves downward relative to the fixed shaft sleeve 105 in the vertical direction, when the top end of the guide rod 106 slides to the second position point, at this time, the second tensile compression spring 107 is in a free state; when continuously sliding to the third position point, the second tensile compression spring 107 is in a compressed state, the pushing force on the operating handle 101 is removed, the operating handle 101 moves backward under the pushing force of the first compression spring 103, thereby having a pushing force to drive the guide rod 106 to move backward, at the same time, the second tensile compression spring 107 has an upward pushing force on the guide rod 106, the resultant force makes the top end of the guide rod 106 slide to the fourth position point, and because the fourth position point is a turning point, the guide rod 106 is clamped to the fourth position point, the guide rod 106 is fixed in position, thereby fixing the operating handle 101 in position, in a retracted state, i.e. hidden in the workpiece, at this time, the retraction assembly 100 is in a handle retraction lock state; that is, the operating handle 101 is hidden in the workpiece, so that the workpiece has more safety and beauty in appearance.

[0086] Step 1.3, conversion of the handle retraction lock state to the handle extension state:

[0087] When the retraction assembly 100 is in the handle retraction lock state, the operating handle 101 is pushed forward, the operating handle 101 gives the guide rod 106 a forward movement pushing force, the second tensile compression spring 107 has an upward pushing force on the guide rod 106, the resultant force makes the top end of the guide rod 106 slide from the fourth position point to the fifth position point, at this time, the operating handle 101 moves to the deepest position, the first compression spring 103 is in a tensile state, at this time, the pushing force on the operating handle 101 is removed, the operating handle 101 starts to move backward to the handle extension position under the pulling force of the first compression spring 103, at the same time, a backward movement pulling force is given to the guide rod 106, the second tensile compression spring 107 has an upward pushing force on the guide rod 106, the resultant force makes the top end of the guide rod 106 slide along the convex arc-shaped guide rail from the fifth position point back to the first position point, specifically, the spring force of the first compression spring 103 is much larger than that of the second tensile compression spring 107, so that the operating handle 101 is sufficient to overcome the resistance to return to the first position point, at this time, the operating handle 101 is in an extended state, the operating handle 101 can be operated, at this time, the retraction assembly 100 is in a handle extension state.

[0088] Step 2, when the retraction assembly 100 is in the handle extension state, rotate the operating handle 101 by a certain angle, for example 90°, in the set rotation direction, the operating handle 101 drives the sliding frame body 102 to rotate, thereby driving the guide rail plate 201 and the gear 203 to rotate;

[0089] When the gear 203 rotates, the rack 206 is driven to move horizontally, thus driving the guide plate 205 to move horizontally, and further driving the positioning pin shaft 207 to descend into the holes of the kitchen insert lock hole K1 and the cabinet lock hole K2, thereby realizing the locking function between the kitchen insert and the cabinet;

[0090] Step 3, then, the operation of the retracting assembly 100 is performed to convert the retracting assembly 100 into the handle retracted locked state, at this time, the handle 101 is hidden in the kitchen insert;

[0091] Step 4, when the unlocking between the kitchen insert and the cabinet is needed, the operation of the retracting assembly 100 is performed to convert the retracting assembly 100 into the handle extended state, and then the handle 101 is reversely rotated to drive the positioning pin shaft 207 to ascend and leave the holes of the kitchen insert lock hole K1 and the cabinet lock hole K2, thereby realizing the unlocking function between the kitchen insert and the cabinet.

[0092] The present application provides a quick locking device and method, which has the advantages of being retractable and hidden and only needing manual operation, and can effectively solve the defects that the civil aviation kitchen insert cannot be hidden or needs to be operated by means of tools.

[0093] The above description is only the preferred embodiments of the present application, and it should be pointed out that, for ordinary skilled in the art, several improvements and refinements can be made without departing from the principles of the present application, and these improvements and refinements should be considered as the protection scope of the present application.

5. A method for a quick locking device as described in claim 3 or 4, characterized in that, Includes the following steps: Step 1, the retractable assembly (100) has a handle extended state and a handle retracted and locked state. By pressing the operating handle (101), the retractable assembly (100) can switch between the handle extended state and the handle retracted and locked state. Step 2: When the retractable component (100) is in the handle extended state, rotate the operating handle (101) by a certain angle according to the set rotation direction. The operating handle (101) drives the sliding frame (102) to rotate, thereby driving the guide plate (201) and gear (203) to rotate. When the gear (203) rotates, it drives the rack (206) to move horizontally, thereby driving the guide plate (205) to move horizontally, which in turn causes the positioning pin (207) to descend and extend into the holes of the kitchen plug-in lock hole (K1) and the cabinet lock hole (K2), thereby realizing the locking function between the kitchen plug-in and the cabinet.

6. The method for a rapid locking device according to claim 5, characterized in that, In step 1, the retraction component (100) switches between the handle extended state and the handle retracted and locked state, specifically as follows: Step 1.1, with your hand extended: When the retraction assembly (100) is in the extended state, the top of the guide rod (106) slides to the first position point of the irregular guide rail (2011), and the second tension compression spring (107) is in the stretched state; since the first compression spring (103) is in the compressed state, it gives the operating handle (101) a push in the extension direction, thereby keeping the handle in the extended state. Step 1.2, the transition from the extended handle state to the retracted and locked handle state: Push the operating handle (101) forward, and the entire assembly formed by the operating handle (101), the sliding frame (102), and the fixed bushing (105) moves forward. At the same time, the fixed bushing (105) drives the guide rod (106) to move forward. When the guide rod (106) moves forward, since the top end of the guide rod (106) is embedded in the irregular guide rail (2011), the top end of the guide rod (106) slides along the irregular guide rail (2011) from the first position point along the concave arc-shaped guide rail with an inflection point, causing the guide rod (106) to move downward relative to the fixed bushing (105) in the vertical direction. When the top end of the guide rod (106) slides to the second position point, the second tension compression spring (107) is in a free state. When it continues to slide to the third position point, the second tension compression spring (107) is in a compressed state, and the thrust on the operating handle (101) is released. The operating handle (101) moves backward under the thrust of the first compression spring (103), thereby having a thrust that drives the guide rod (106) to move backward. At the same time, the second tension compression spring (107) has an upward thrust on the guide rod (106). The combined force causes the top of the guide rod (106) to slide to the fourth position point. Since the fourth position point is a turning point, the guide rod (106) is locked at the fourth position point. The position of the guide rod (106) is fixed, thereby fixing the position of the operating handle (101) and putting it in a retracted state, i.e., hidden inside the kitchen insert. At this time, the retracting assembly (100) is in the handle retracted and locked state. Step 1.3, the transition from the handle retracted and locked state to the handle extended state: When the retraction assembly (100) is in the retracted and locked state, pushing the operating handle (101) forward creates a forward thrust on the guide rod (106). The second tension compression spring (107) exerts an upward thrust on the guide rod (106), and the combined force causes the top of the guide rod (106) to slide from the 4th position point to the 5th position point. At this time, the operating handle (101) moves to its deepest position, and the first compression spring (103) is in the stretched state. Releasing the thrust on the operating handle (101) at this point allows the operating handle to resume operation. The handle (101) begins to move backward to the handle extension position under the pull of the first compression spring (103), and at the same time, it provides a pull force to the guide rod (106) to move backward. The second tension compression spring (107) has an upward pushing force on the guide rod (106). The combined force causes the top of the guide rod (106) to slide back from the 5th position point to the 1st position point along the raised arc-shaped guide rail. The operating handle (101) is in the extended state, and the operating handle (101) can be operated. At this time, the retraction assembly (100) is in the handle extension state.
