The shell 10 is provided with a first through hole 15 and a second through hole 16; the first through hole 15 is used for the key 20 to pass through; the second through hole 16 is used for the telescopic rod 30 to pass through; specifically, the first through hole 15 longitudinally penetrates through the top case 12, and the key 20 can move along the first through hole 15 in the longitudinal direction; the second through hole 16 transversely penetrates through the bottom shell 11 and the top shell 12, and the telescopic rod 30 can move along the second through hole 16 in the transverse direction;
the key 20 is elastically connected to the housing 10; in this embodiment, a first elastic connection portion 17 is provided in the housing 10; the key 20 is provided with a second elastic connection portion 21 corresponding to the first elastic connection portion 17; a first spring 60 is connected between the first elastic part and the second elastic connecting part 21; specifically, the first elastic connection portion 17 is disposed on the bottom shell 11, and is a column; the second elastic connection part 21 comprises a groove body arranged on the bottom surface of the key 20 and a boss arranged on the groove body, the boss is axially aligned with the column, and the first spring 60 is connected between the column and the boss; the first spring 60 can be assembled conveniently by the structural design, and compression rebound is not run;
the size of the key 20 is limited, the springs are generally only smaller than the width of the key 20, the key 20 is in a long strip shape, and in order to ensure that the key 20 can keep balance when moving downwards, the first elastic connecting portion 17, the second elastic connecting portion 21 and the first spring 60 are provided with two groups and are symmetrically arranged at the left side and the right side of the center line of the shell 10 respectively; the above structure can ensure the balance of the key 20 under normal conditions, but when the spring at one side fails or fails, the phenomenon of the key 20 deflection will occur, which results in inconsistent key stroke between the left and right pressing, and affects the hand feeling, even the locking lever cannot be retracted and unlocked.
In order to ensure stable key stroke and pressing hand feeling of the key 20, a first guiding part 40 is arranged in the shell 10; the key 20 is provided with a second guiding part 50; the second guide part 50 slides in engagement with the first guide part 40; in this embodiment, the first guide portion 40 and the second guide portion 50 are disposed at a center line of the housing 10; the second guiding part 50 is a dovetail groove; the first guide part 40 is a dovetail guide rail block; when the key 20 is lifted longitudinally, the first guide portion 40 and the second guide portion 50 slide mutually, so that the movement of the key 20 in the front-back direction and the left-right direction is limited, the key can only move along the longitudinal direction, and even if one side spring fails, the key does not deflect, the pressing hand feeling is improved, and the running stability is improved.
The telescopic rod 30 is elastically connected to the casing 10, and the telescopic rod 30 is movably clamped with the key 20; in this embodiment, two telescopic rods 30 are symmetrically arranged and distributed on the left and right sides of the housing 10; the key 20 is connected with a first driving part 22; the telescopic rod 30 is connected with a second driving part 31; the second driving portion 31 is movably clamped with the first driving portion 22, specifically, the first driving portion 22 is a clamping column connected to front and rear end surfaces of the key 20; the second driving part 31 is a guide groove block connected to the telescopic rod 30; the guide groove blocks are provided with driving guide grooves which gradually descend from the center of the shell 10 to the left side and the right side of the shell 10; after assembly, the clamping column is inserted into the driving guide groove, the clamping column can longitudinally lift synchronously along with the key 20, and the guide groove block and the clamping column relatively move, so that the telescopic rod 30 transversely moves to realize insertion unlocking and rollback unlocking with the dial;
further, to increase the unlocking resilience after releasing the key 20, the telescopic rod 30 is connected with a third elastic connection part 32; a fourth elastic connection part 18 is arranged in the shell 10; a second spring 70 is connected between the third elastic connection portion 32 and the fourth elastic portion; specifically, the third elastic connection portion 32 is a column, and is coaxially disposed at the other end of the telescopic rod 30 for inserting into the dial end; the fourth elastic connecting part 18 is a groove structure; by adding the spring at this position, the compression rebound function of the transverse position can be increased, and the working stability can be improved.
Working principle:
as shown in fig. 5, the default state of the quick-release tab is a locked state, the quick-release tab is assembled in the watchband, at this time, the first spring 60 and the second spring 70 are in a rebound state, the key 20 is positioned at the uppermost end of the pressing stroke, the telescopic rod 30 is positioned at the outermost end of the extending stroke, and the first guide part 40 is positioned at the bottom end of the second guide part 50;
as shown in fig. 6, when the key 20 is pressed downwards, the first driving portion 22 drives the second driving portion 31 to slide relatively, so that the telescopic rod 30 connected with the second driving portion 31 gradually contracts towards the center of the housing 10, meanwhile, the first spring 60 and the second spring 70 compress, and when the head end of the telescopic rod 30 is separated from the dial, the watchband and the dial are unlocked, and quick disassembly is achieved. When the locking is needed, the key 20 is released, the first spring 60 and the second spring 70 rebound, the key 20 and the telescopic rod 30 are reset and pop up, the head end of the telescopic rod 30 is inserted into the corresponding position of the dial, and the locking of the watchband and the dial is completed.
When the above-mentioned locking state, unlocking state, and switching between two states, the first guiding portion 40 and the second guiding portion 50 are in sliding fit with each other, so that the key 20 can be ensured to move only along the longitudinal direction, and even if one side spring fails, the spring does not deflect, the pressing hand feeling is improved, and the running stability is improved.
Example 2:
the present embodiment is substantially the same as embodiment 1, except that only one set of telescopic rods 30 is provided, and as shown in fig. 7, a fixing pin 80 is provided at the other end of the housing 10 opposite to the telescopic rods 30. When the telescopic handle is used, the key 20 is pressed firstly to enable the telescopic rod 30 to shrink, at the moment, one end of the lug with the fixing pin is inserted into the dial, the other end of the lug is pushed into the mounting end of the other side of the dial, the key 20 is loosened, and the telescopic rod 30 is inserted into the dial in a rebound mode to finish locking.
The technical features of the above-described embodiments may be arbitrarily combined, and all possible combinations of the technical features in the above-described embodiments are not described for brevity of description, however, as long as there is no contradiction between the combinations of the technical features, they should be considered as the scope of the description.
