Description

Technical Field

[0001] This utility model relates to the field of watch fastener technology, and in particular to a convenient unlocking fastener. Background Technology

[0002] Watch clasps, typically made of stainless steel or titanium, are the movable part of the watch strap. Traditional watch clasps include: hook clasps, concealed clasps, butterfly clasps, leather snap clasps, folding safety clasps, and pin buckles. Folding clasps, with their folding structure, are commonly used with metal or partially leather straps. They secure the strap by folding and closing, and are the most widely used type of traditional watch clasp.

[0003] The folding clasp in existing watch clasps requires manual prying to lock and unlock, which necessitates a certain level of learning ability and operational skills, making it inconvenient in actual use. Utility Model Content

[0004] To overcome the shortcomings of existing watch fasteners that require manual opening and closing, which presents an operational hurdle and is inconvenient to use, this utility model provides a convenient unlocking fastener.

[0005] The technical solution is as follows: A convenient unlocking fastener includes a fastener base, a snap fastener, a first torque spring, a base, a lever, a second torque spring, and a fastener pin. The snap fastener is hinged to the left end of the fastener base. The first torque spring is provided at the connection between the snap fastener and the fastener base. A fastener pin is provided at the bottom of the snap fastener. A through hole is opened in the middle of the fastener base. A rectangular hole is opened on the rear side of the fastener base. A base is provided at the bottom of the fastener base. A lever is rotatably connected to the top of the base. A second torque spring is provided at the connection between the lever and the base. The lever is located in the rectangular hole. A guide slope is designed below the fastener pin. A pressure-bearing slope is designed at the top of the lever. The pressure-bearing slope and the guide slope are mutually compatible. A groove is opened at the lower middle part of the lever. The groove fits with the fastener pin.

[0006] As a further preferred embodiment, the buckle and the base are detachably connected by bolts.

[0007] As a further preferred embodiment, the contact surfaces of the base and the bottom of the buckle are completely flat and fit together.

[0008] As a further preferred embodiment, the rear portion of the lever extends outward from the rectangular hole.

[0009] As a further preferred embodiment, the edges of the exposed extension portion of the lever are chamfered.

[0010] As a further preferred option, it also includes an anti-slip protrusion, with an anti-slip protrusion provided at the rear right end of the lever.

[0011] The present invention has the following advantages: 1. The present invention has a low operating threshold and requires no additional learning ability or operating foundation. Whether locking or unlocking, it can be completed by simple pressing and flicking actions, avoiding the defects of existing folding buckles that require manual bending and complicated operation. It can be used by anyone.

[0012] 2. The locking and unlocking process of this utility model is efficient and labor-saving. When locking, pressing the snap button will automatically engage and lock the device. When unlocking, simply move the back of the lever. No complicated steps are required, which improves the ease of use. Attached Figure Description

[0019] The present invention will be further described below with reference to specific embodiments. It should also be noted that, unless otherwise explicitly specified and limited, terms such as "setting," "installing," "connecting," and "linking" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in the present invention based on the specific circumstances.

[0020] A convenient unlocking connector, such as Figures 1-5As shown, the watch includes a buckle base 1, a snap 2, a first torque spring 201, a base 3, a lever 4, a second torque spring 403, and a clasp 5. The snap 2 is hinged to the left end of the buckle base 1, and the right end of the buckle base 1 is used to connect the watch strap. The first torque spring 201 is located at the connection between the snap 2 and the buckle base 1. The clasp 5 is located at the bottom of the snap 2. A through hole 101 is opened in the middle of the buckle base 1, and a rectangular hole is opened on the rear side of the buckle base 1. The base 3 is located at the bottom of the buckle base 1. The buckle base 1 and the base 3 are detachably connected by bolts, which facilitates the disassembly and maintenance of the lever 4 and the second torque spring 403. The contact surface between the base 3 and the bottom of the buckle base 1 is completely flat and fits perfectly, ensuring a comfortable fit on the user's wrist without any discomfort when worn. To improve the fit of the overall structure, a lever 4 is rotatably connected to the top of the base 3. The rear of the lever 4 extends outward from the rectangular hole, making it convenient for the wearer to move the lever 4 to unlock. The exposed extension of the lever 4 has a chamfered edge to prevent sharp edges from scratching the skin or clothing, thus improving the comfort and safety of operation and wearing. A second torque spring 403 is provided at the connection between the lever 4 and the base 3. The lever 4 is located in the rectangular hole. A guide slope 501 is designed below the buckle 5. A pressure-bearing slope 401 is designed at the top of the lever 4. The pressure-bearing slope 401 and the guide slope 501 are compatible with each other. A groove 402 is opened in the lower middle part of the lever 4, which fits with the buckle 5.

[0021] like Figure 4 As shown, it also includes an anti-slip protrusion 404. The right end of the rear part of the lever 4 is provided with an anti-slip protrusion 404. The anti-slip protrusion 404 can increase the friction when the lever is turned, making it easier for the wearer to manually unlock the lever and less prone to slipping.

[0022] In use, the wearer places the watch with the clasp on their wrist, then passes the watch's tail ring under the clasp 2 and manually presses the clasp 2 to push the clasp 5 down. The guide slope 501 at the lower end of the clasp 5 engages with the pressure-bearing slope 401 at the top of the lever 4. Continuing to press down, the lever 4 rotates around its connection point with the base 3. Once the clasp 5 contacts the upper surface of the base 3, it embeds into the groove 402. At this point, releasing the clasp 2 causes the first torque spring 201 to provide an upward rebound force, pressing the groove upwards. 402, which makes the buckle 5 fit more tightly with the inner wall of the groove 402. The second torque spring 403 will provide a lateral elastic preload to the lever 4, further enhancing the fitting and locking effect between the buckle 5 and the groove 402. When it is necessary to unlock this connecting buckle, simply move the rear of the lever 4. The lever 4 rotates, and the groove 402 separates from the bottom of the buckle 5. At this time, the rebound force of the first torque spring 201 will drive the snap button 2 to pop up automatically. The buckle 5 will exit the through hole 101 of the buckle seat 1 at the same time as the snap button 2, and the connecting buckle can be quickly unlocked. The operation is simple and effortless.

[0023] The technical principles of the present invention have been described above with reference to specific embodiments. These descriptions are merely for explaining the principles of the present invention and should not be construed as limiting the scope of protection of the present invention in any way. Based on this explanation, those skilled in the art can conceive of other specific embodiments of the present invention without creative effort, and these embodiments will all fall within the scope of protection of the present invention.
