DETAILED DESCRIPTION

[0027] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0028] Example

[0029] See Figures 1 to 3 As shown, a watch case with a quick-release watchband structure comprises an upper watch base 1, an inner liner 2 and a watchband buckle 3, wherein the outer diameter of the inner liner matches the inner diameter of the watchband buckle.

[0030] During installation, the inner shell is arranged on the inner side of the watch strap buckle, and the upper seat is arranged on the top of the watch strap buckle. The above assembly is a conventional structure of the prior art, so it is not described in detail. In this embodiment, at least three card cavities 4 are arranged at equal intervals on the inner wall of the watch strap buckle, and a plastic card 5 is adhered in the card cavity. In this embodiment, the number of the card cavity and the plastic card is three, four or five. The inner side of the plastic card protrudes from the inner surface of the watch strap buckle; at the same time, a card groove 6 is arranged on the outer wall of the inner shell, and the position matches the position of the card cavity; the height of the card groove is less than the height of the card cavity. During assembly, a stop convex edge is arranged on the upper part of the outer wall of the inner shell; the inner shell is clamped in the watch strap buckle, and the inner side of the plastic card is clamped in the clamp groove of the inner shell; the inner wall of the upper seat is pressed against the top surface of the stop convex edge. The liner is set on the inner side of the strap buckle and is locked in place by plastic clips, which not only improves the convenience of disassembly and assembly, but also plays a role in friction and fixing to ensure the stability and reliability of the connection. It can also prevent the movement from slipping under force, thereby improving the effectiveness of use.

[0031] In this embodiment, the cross section of the plastic card includes a "7"-shaped pressing portion 51, a pressing convex edge 52 integrally formed at the left end of the top surface of the "7"-shaped pressing portion, and a positioning block 53 integrally formed at the bottom end of the "7"-shaped pressing portion; in this embodiment, the left end is for the convenience of explanation and is not intended to limit it. During installation, the top edge of the pressing convex edge and the bottom edge of the positioning block are pressed against the top wall and bottom wall of the card cavity respectively and bonded to position; the corner of the "7"-shaped pressing portion protrudes from the inner surface of the watchband buckle and is inserted into the positioning groove of the liner. After installation, the corner of the "7"-shaped pressing portion presses against the top wall of the positioning groove to limit the position of the liner, which is highly practical.

[0032] In actual application, the thickness of the pressing convex edge and the stop block is 1 / 2 of the depth of the card cavity; a pressing frame 7 is arranged outside the pressing convex edge and the stop block; the inner surface of the pressing frame matches the inner surface of the watchband buckle after installation. The pressing frame is used to press and limit the plastic card to ensure the stability and reliability of its installation position, and at the same time, it will not affect the normal installation and use of the liner.

[0033] In actual application, the upper seat is an inclined seat inclined toward the center; the upper seat is provided with a pressing step 8 and an inclined pressing surface 9; during installation, the top end and the pressing convex edge of the strap buckle are respectively pressed against different surfaces of the pressing step, and the inclined pressing surface is attached to the top of the outer surface of the liner. In this embodiment, the inclined pressing surface matches the upper surface of the outer wall of the liner, so that after installation, the inclined pressing surface is attached to the top of the outer surface of the liner, which not only ensures the effectiveness of the connection, but also ensures the stability of the position of the connection through the above structure, and is also conducive to improving the overall appearance.

[0034] In actual application, the watchband buckle is provided with a crown avoidance groove 10 for installing the movement crown. In this embodiment, the crown avoidance groove is mainly used for installing the movement crown.

[0035] It is further preferred that: the utility model has positive effects: the structure of the utility model is reasonably arranged, and there is a card cavity on the inner wall of the watch strap buckle, and at the same time there is a plastic card block in the card cavity, and cooperates with the card groove on the outer wall of the inner liner. When the inner liner is connected to the watch strap buckle, the card connection can be achieved through the plastic card block, which not only has a friction and fixing effect, but also can prevent the movement from sliding down under force, ensuring the stability and reliability of use, and can also realize the rapid disassembly and assembly of the watch strap buckle, improving the convenience of disassembly and assembly, and has strong applicability and good practicality.

[0036] The standard parts used in this embodiment can be purchased directly from the market, and the non-standard structural components recorded in the specification can also be directly processed according to existing technical common sense. At the same time, the connection method of each component adopts the mature conventional means in the prior art, and the machinery, parts and equipment all adopt the conventional models in the prior art, so no specific description will be given here.

[0037] Obviously, the above embodiments of the present invention are merely examples for clearly explaining the present invention, and are not intended to limit the implementation methods of the present invention. For ordinary technicians in the relevant field, other different forms of changes or modifications can be made based on the above description. It is not necessary and impossible to list all the implementation methods here. However, these obvious changes or modifications derived from the essential spirit of the present invention still belong to the protection scope of the present invention.
