Description

Technical Field

[0001] The present invention relates to the technical field of watchband quick-release devices, in particular to a key switch type ear-opening mechanism. Background Art

[0002] Existing watch straps generally use spring tabs to connect the dial to the strap. The traditional spring tab structure consists of a rod and spring pins elastically connected to both ends of the rod. When disassembling, special screw pins need to be inserted from both ends of the strap to compress the spring pins, causing the spring pins to loosen from the strap. This makes assembly and disassembly complicated and inconvenient for users to replace the strap by themselves.

[0003] To this end, watch manufacturers have developed spring tabs that use buttons for unlocking, such as publication number CN217065569U, entitled "Chinese Invention of a Quickly Removable Strap and Dial Connection Structure and Watch." This system includes a head, a cover, a button, a spring, a spring tab, a buckle, and a ball bearing. The buckle and the spring tab are interlaced and connected within the head, with one end of the buckle connected via a ball bearing and the other end connected to the wall of the head via a spring. Pressing the button retracts the spring tab toward the head to unlock the watch. While this solution eliminates the need for an external screw pin for unlocking, increasing unlocking efficiency, it requires screws to connect the buckle and the spring tab, and a ball bearing to connect the spring tab and the buckle. This results in numerous parts, a complex structure, high manufacturing costs, and significant assembly difficulties. Therefore, improvements are needed. Summary of the Invention

[0004] Based on this, the present invention provides a key switch type ear-opening mechanism.

[0005] In order to achieve the purpose of the present invention, the present invention adopts the following technical solutions:

[0039] like Figures 1-9 As shown,

[0040] A push-button switch type ear mechanism includes a housing 100, an abutment member 200, an ear 300, and a button 400;

[0041] The housing 100 provides overall load-bearing function;

[0042] In this embodiment, the housing 100 includes a bottom cover 110 and a top cover 120 ; the bottom cover 110 and the top cover 120 are welded together;

[0043] The housing 100 is provided with a longitudinal lifting groove 130 ; the bottom cover 110 is provided with three connecting posts 131 at the interface with the longitudinal lifting groove 130 ; the three connecting posts 131 are arranged in a triangular pattern, providing a stable guiding effect;

[0044] The housing 100 is provided with a transverse slot 140 connected to the longitudinal lifting slot 130. The transverse slots 140 are located on either side of the longitudinal lifting slot 130 and are connected to the wall of the housing 100 through holes 141. A snap ring 142 is provided in the transverse slot 140 away from the hole 141. The bottom cover 110 has an upwardly protruding cover plate 143 in an area corresponding to the hole 141, so that the hole 141 is positioned in the bottom cover 110 to facilitate subsequent alignment and assembly of the spring ears 300.

[0045] The abutment member 200 is slidably assembled in the housing 100 , and a first elastic member 210 is connected between the abutment member 200 and the wall of the housing 100 ;

[0046] In this embodiment, the abutting member 200 is provided with a connecting groove 220 that fits with the connecting post 131, so that the abutting member 200 can be raised and lowered longitudinally along the connecting post 131. The first elastic member 210 is a spring and is sleeved on the connecting post 131. One end of the first elastic member 210 abuts against the inner wall of the bottom cover 110, and the other end abuts against the abutting member 200.

[0047] The left and right side walls of the abutment member 200 are connected to mutually connected sliding inclined surfaces 230 and abutting straight surfaces 240; the sliding inclined surfaces 230 are inclined upward from the transverse sliding groove 140 to the longitudinal lifting groove 130, and the abutting straight surface 240 is away from the abutment member 200 and is connected to the lowest end of the sliding inclined surfaces 230;

[0048] The abutment 200 is provided as a transmission member between the button 400 and the ear 300, and has the functions of guiding lifting and transmission, and can slide relative to the ear 300, so that the ear 300, the first elastic member 210 and the second elastic member 310 are linked to achieve the function of locking and unlocking the watchband. The abutment 200 is provided with a connecting groove 220 corresponding to the triangularly distributed connecting column 131 to achieve stable lifting; the left and right side walls of the abutment 200 are connected with a sliding inclined surface 230 and an abutting straight surface 240, which respectively match the retracted state and the extended state of the ear 300, and the transmission is stable. Compared with the previous method of using the button 400 to directly move relative to the ear 300, this method is more adaptable to use in the case where the housing 100 has a complex inner cavity structure, reduces the design difficulty of the button 400, and greatly improves the stability of use;

[0049] The spring ears 300 are provided in two sets and are slidably assembled at the left and right ends of the housing 100, respectively, and slidably abut against the side walls of the abutment member 200; a second elastic member 310 is connected between the spring ears 300 and the wall of the housing 100;

[0050] In this embodiment, the spring ear 300 includes a protruding portion 320, a clamping portion 330, and an abutting round-headed rod 340, which are connected in sequence. The protruding portion 320 and the clamping portion 330 are correspondingly located in the transverse sliding groove 140. The abutting round-headed rod 340 passes through the clamping ring 142 and slidably abuts against the abutting member 200. The second elastic member 310 is a spring and is sleeved on the protruding portion 320. One end of the second elastic member abuts against the wall of the bottom cover 110, and the other end abuts against the clamping portion 330.

[0051] One end of the button 400 is connected to the abutment member 200 , and the other end extends out of the housing 100 ;

[0052] In this embodiment, the top cover 120 in the shell 100 is provided with a through slot 150; the through slot 150 is adjacent to the inner wall surface of the top cover 120 and is provided with a first alignment portion 151; the button 400 includes a cap body 410 and a base 420 connected to each other; the cap body 410 is matched with the through slot 150; the outer diameter of the base 420 is larger than the outer diameter of the through slot 150, and the base 420 is provided with a second alignment portion 421 that is matched with the first alignment portion 151; the first alignment portion 151 is a boss structure, and the second alignment portion 421 is a matching groove structure, which can ensure the accurate lifting and lowering of the button 400 and ensure the stability of the use of the Bensen ear 300 mechanism.

[0053] Working principle:

[0054] In the default state, the first elastic member 210 is in a rebound state. At this time, the button 400 and the abutting member 200 are raised, and the abutting straight surfaces 240 on the left and right sides of the abutting member 200 abut against the abutting round-headed rod 340 in the spring ear 300, causing the spring ear 300 to compress the second elastic member 310 and push it out into the hole 141, locking the watchband. To unlock the watchband, the button 400 is pressed, causing the button 400 and the abutting member 200 to descend and compress the first elastic member 210. The abutting inclined surfaces on the left and right sides of the abutting member 200 abut against the abutting round-headed rod 340 in the spring ear 300. As these abutting inclined surfaces gradually descend, the second elastic member 310 gradually rebounds, causing the spring ear 300 to retract into the housing 100, ultimately unlocking the watchband.

[0055] The technical features of the above-mentioned embodiments can be combined arbitrarily. In order to make the description concise, not all possible combinations of the technical features in the above-mentioned embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0056] The above-described embodiments merely illustrate several implementations of the present invention, and while their descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the patent. It should be noted that a person skilled in the art would be able to make numerous variations and improvements without departing from the spirit of the present invention, all of which fall within the scope of protection of the present invention. Therefore, the scope of protection of the patent for this invention shall be determined by the appended claims.
