[0002] A watch is mainly composed of a strap and a watch body. Whether it is the need to replace the strap to improve its diversity during use, or the need to remove the strap for repair when it is damaged during use. Therefore, the connection design between the strap and the watch body needs to be designed to be detachable. Generally, the watch body and the strap are connected through spring ears. The spring ear is a connecting steel shaft between the strap and the watch body. When it needs to be disassembled, the spring ear needs to be removed. Most existing designs require special tools for disassembly, and it is difficult to disassemble and assemble by hand or by non-professional personnel.

[0020] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0021] Figure 1 It is an overall schematic diagram of a watch using a strap-changing head structure with an automatically ejectable connector; Figure 2 It is a partial exploded schematic diagram of the lug of a watch using a strap-changing structure with an automatically ejectable connector; Figure 5The watch with the strap head structure that can automatically pop out the connector includes a strap B and a watch body A. The watch body is symmetrically provided with two lugs and matching lugs 10. The strap B is connected to the watch body through the lugs 10. The lugs include a left sub-lug and a right sub-lug. The left sub-lug is a fixed lug 4. The inner side of the left sub-lug is provided with a first lug hole 5 that is closed at one end. The right sub-lug includes a lug mounting frame 1, a fixed spring pin 9, a positioning spring 8 and a movable lug 7. The outer side of the lug mounting frame 1 is provided with a sliding groove in the horizontal direction. The groove width of the sliding groove is slightly larger than the width of the movable lug 7. The movable lug 7 can slide freely in the horizontal direction in the sliding groove without external force. The bottom of the sliding groove is provided with a limiting sliding groove 6. The sliding groove is provided with a spring pin mounting hole 12 on the side of the watch body along the sliding groove direction. The spring pin mounting hole 12 The aperture of the spring pin 9 is matched with the aperture of the fixed spring pin 9, and the sliding groove is provided with a raw ear through hole 2 whose aperture is slightly larger than the raw ear axis diameter along the axial direction of the raw ear at the end away from the watch body; the movable watch ear is provided with an arc-shaped recessed portion 71 along the axial inner side of the raw ear, and the movable watch ear is provided with a positioning spring mounting groove 72 on the side facing the sliding groove; a raw ear spring 3 is provided in the first raw ear hole; the fixed spring pin 9 is installed on the spring pin mounting hole 12, one end of the positioning spring is arranged in the positioning spring mounting groove 72, and the other end is sleeved on the fixed spring pin 9, the positioning spring presses the movable watch ear to the end away from the watch body, the arc-shaped recessed portion 71 is opposite to the raw ear 10, and the raw ear is pressed between the movable watch ear and the fixed watch ear; when the movable watch ear overcomes the elastic force of the positioning spring and is completely pushed to the side of the watch body, the movable watch ear is completely separated from the shielding raw ear through hole.

[0022] Figure 3 It is a cross-sectional view of the lug part of the watch ear being pressed into the state; during installation, first install the lug spring 3 into the first lug hole 5, and pass the lug 10 through the lug through-hole 2 and the strap head and extend into the first lug hole 5; the movable lug 7 can also be installed, specifically, first install the fixed spring pin 9 on the spring pin mounting hole 12, install one end of the positioning spring 8 in the positioning spring mounting groove 72, and the other end passes through the fixed spring pin 9; press the positioning spring 8, press the movable lug 7 into the sliding groove, and install the upper limit convex part on the limiting convex part mounting hole of the movable lug 7 from the outside of the limiting slide groove 6. A simplified structure is screwed in the screw 11; the nut diameter of the screw 11 is larger than the width of the limiting slide groove 6, and the diameter of the rotating part is smaller than the width of the limiting slide groove 6; the installation of the movable lug 7 is realized, and the movable lug 7 is pressed toward the end away from the watch body by the positioning spring when there is no external force, such as Figure 3 In this state, the arc-shaped recess 71 is directly opposite to the spring ear 10, so that the watchband is fixed. Figure 4It is a cross-sectional view of the lug of the watch ear in the pop-up state; when the watch strap needs to be replaced, no external force is required, and the movable lug 7 is directly pushed by hand to overcome the elastic force of the positioning spring and push the movable lug 7 away from the lug through hole 2. When it is completely pushed away, the lug is automatically popped out due to the elastic force of the lug spring 3, and the operation is very convenient and simple. In order to facilitate the pushing of the movable lug 7, the two ends of the lug 10 are preferably set to a hemispherical or curved design. The corresponding curved convex part is a semi-spherical, 1 / 3 spherical or 1 / 4 spherical.

[0023] In order to prevent the spring from deforming after long-term use and accidentally failing to pop out by itself, the bottom of the first ear hole 5 can also be designed to be through-hole, and the through-hole diameter is smaller than the diameter of the ear spring 3. It is convenient to push the ear out through the through-hole in case of an accident.

[0024] The above disclosure is only one embodiment of the present invention, which certainly cannot be used to limit the scope of the present invention. Ordinary technicians in this field can understand that all or part of the processes of the above embodiment can be implemented, and equivalent changes made according to the claims of the present invention still fall within the scope of the invention.
