It should be understood that the specific embodiments described herein are merely illustrative of the invention and are not intended to limit the invention.
As shown in FIG. 1, be the embodiment of the utility model provides a structure schematic diagram of the watchcase of adjustable watchband elasticity, the watchcase of this adjustable watchband elasticity can be applied to wearing equipment technical field, and uses but the watchcase greatly reduced of this adjustable watchband elasticity to the material of watchband and structural design's requirement.
Referring to fig. 2, the watch case capable of adjusting the tightness of the watch band in the present embodiment includes a main case 1, a driving element 2, a spring locking assembly 3, and a pulling member 4, wherein the pulling member 4 is used for connecting to the head end of the watch band 5 to drive the watch band 5 to move by pulling, so as to achieve tightness adjustment. The traction means 4 is embodied as a flexible structure, which facilitates the retraction of the same without taking up a large space, such as a chain.
Specifically, driving piece 2 and spring locking subassembly 3 are installed respectively on main casing body 1, and driving piece 2 is connected with spring locking subassembly 3 (preferably connect with the mode of joint, and the joint mode is firm reliable, and is favorable to structural design) to accessible spring locking subassembly 3 fixes driving piece 2, realizes that driving piece 2 reliably opens and stops, spacing fixed driving piece 2 promptly, prevents that driving piece 2 from removing and causing the drive inefficacy.
The spring locking assembly 3 of the present embodiment comprises a locking member 31 and an opening and closing member 32, wherein the locking member 31 is connected with the driving member 2 to limit and fix the driving member 2. The switch member 32 is used to drive the locking member 31, and particularly when the switch member 32 is driven (i.e. pressed), the switch member 32 pushes the locking member 31 to move and contract in a direction away from the driving member 2, so that the locking member 31 is separated from the driving member 2, and thus the driving member 2 is not limited and fixed by the locking member 31 and can be normally driven by force.
Further, driving piece 2 is connected and is drawn member 4, and when retaining member 31 breaks away from driving piece 2, draw member 4 and drive under the drive of driving piece 2 the head end of watchband 5 (for main casing body 1) along the length direction removal of watchband 5 to increase or shorten the distance between two head ends of watchband 5, realize wearing length's adjustment (the length of actually wearing specifically comprises watchband 5 and a part of drawing member 4), and then reach the elasticity adjustment function to watchband 5. Moreover, the driving element 2 is preferably detachably connected with the pulling member 4, so that not only can the reliable connection between the pulling member 4 and the head end of the watchband 5 be ensured, but also the disassembly, assembly and maintenance operations of the watchband 5 are facilitated.
Above-mentioned watchcase of adjustable watchband elasticity is through setting up traction member 4, and the head end that drives watchband 5 with the mode of tractive by traction member 4 removes, has realized wearing the adjustment of length, and this simple structure is reasonable, and the drive mode is also comparatively reliable practical. And, adopt and pull member 4 and more be favorable to structural design, can make during the drive pull member 4 warp the shrink, both reduced the space that fuses to accomodate, can design around the structure of main casing 1 again to realize the reduction of volume.
In addition, because the watchcase generally all installs the dial plate subassembly that is used for showing the time, the volume is usually detained than the table greatly, consequently with driving piece 2 and spring locking subassembly 3 integrated respectively on main casing body 1, can further improve the designability of structure like this, effectively avoid the increase of table knot volume, both guaranteed the travelling comfort of wearing, make the outward appearance more pleasing to the eye again.
In an embodiment of the present invention, the two sides of the main housing 1 are respectively provided with a sliding channel along the length direction of the watchband 5, and the shape and size of the sliding channel are adapted to the shape and size of the head end of the watchband 5.
