[0013] Preferably, in the pressed state, one side of the end of the top block is in contact with the end step of the ear, and the elastic force of the return spring can overcome the air pressure of the micro-sleeve airbag and the micro-cylindrical airbag in the natural state. The elastic force provided by the return spring is much smaller than the elastic force of the ear spring.

[0014] Preferably, the limiting assembly includes a protruding seat, which is located on one side of the pressing groove and fixed on the watch strap. A groove is provided on the protruding seat, and a mounting circular plate is provided at the opening of the groove.

[0015] Compared with the prior art, the present invention has the following beneficial effects:

[0016] 1. The present invention allows users to quickly remove and install the watch strap with a simple press, greatly facilitating the strap replacement process without the need for additional tools or skills. The design of the limit assembly allows users to press the strap without having to continue pressing. The insert will automatically lock the strap in place, simplifying the operation process and making it easier for users to perform other operations.

[0017] 2. The present invention ensures the stability of the watchband in its natural state and its safety during operation through designs such as the pressing spring, the ear spring, and the torsion spring in the abutment assembly. In particular, the friction force on the inner side of the sleeve at the connection between the abutment block and the watchband is increased, thereby improving the reliability of the quick-release structure.

[0018] 3. The micro cylindrical airbag and micro sleeve airbag in the push assembly of the present invention use the pneumatic transmission principle to reduce direct dependence on the ear spring, which helps to extend the service life of the ear spring and avoid the problem of loss of elasticity due to aging of the ear spring. The abutment component design at the end of the ear can automatically adjust its position during the extension and contraction process of the ear, ensuring smooth disassembly and installation actions and improving user experience.

DETAILED DESCRIPTION

[0030] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. 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 making creative efforts are within the scope of protection of the present invention.

[0031] See also Figure 1 The figure is an exploded schematic diagram of a push-button switch type quick-release spring ear structure of the present invention. The present invention provides a technical solution: a push-button switch type quick-release spring ear structure, comprising a watch strap 1 and spring ears 2. Ear holes 11 are formed at both ends of the watch strap 1. Two spring ears 2 are located in the ear holes 11 of the watch strap 1. The ends of the spring ears 2 form a stepped structure opening toward the ear holes 11. One end of the spring ears 2 has an inclined surface structure. A pressing groove 12 is formed on the watch strap 1, and a watch strap button 6 is placed in the pressing groove 12. The surfaces of the ear holes 11 and the pressing groove 12 on the watch strap 1 are both made of hard materials. The entire watch strap 1 is made of a composite material.

[0032] Figure 2 This is a schematic diagram of the structure of the push-button switch type quick-release spring ear structure in its natural state. Figure 3 This is a structural schematic diagram of the push-button switch-type quick-release ear structure of the present invention in the pressed state. A slot is provided on the strap button 6, and a pressing spring 5 is fixedly connected between the strap button 6 and the pressing slot 12. The pressing spring 5 presses against the slot of the strap button 6. Bevel grooves are provided on both sides of the strap button 6. The inclined surface of the ear 2 contacts the bevel groove of the strap button 6. A ear spring 3 is sleeved on the ear 2. A strap nut 4 is screwed on the opening of the ear hole 11 on the strap 1. The strap nut 4 is fixedly screwed on the strap 1 to limit the ear spring 3 and the ear 2.

[0033] Figure 2This is a structural schematic diagram of the push-button switch type quick-release spring ear structure of the present invention in its natural state. The spring ear 2 passes through the small hole of the strap nut 4. A step is made on the axis of the spring ear 2 passing through the small hole of the strap nut 4, which limits the length of the spring ear 2 extending out of the strap nut 4 and hooks the strap button 6 to prevent it from falling off. The spring ear spring 3 pushes the spring ear 2 toward the button spring 5. The elastic force provided by the button spring 5 causes the strap button 6 to push the spring ear 2 toward the strap button 6. The elastic force provided by the button spring 5 is much greater than the elastic force of the spring ear spring 3. In the natural state, the spring ear 2 presses the strap nut 4.

[0034] In its natural state, the inclined surface of the strap button 6 presses against the inclined surface of the ear 2, causing the ear 2 to move outward toward the ear hole 11, completing the extension of the ear 2; when the strap button 6 is pressed, the ear spring 3 presses against the ear 2 and moves toward the pressing spring 5, shortening the length of the ear 2 extending from the strap nut 4, completing the contraction of the ear 2, and allowing the ear 2 to fall off the dial, making it easier to install and disassemble.

[0035] Figure 4 This is a structural schematic diagram of the end of the spring ear of the present invention. The end of the spring ear 2 is provided with an abutment assembly that is easy to adjust automatically. The abutment assembly includes a receiving groove 21. Receiving grooves 21 are provided on both sides of the end of the spring ear 2. A fixing pin 22 is fixedly inserted in the receiving groove 21 on the spring ear 2. An abutment block 24 is rotatably sleeved on the fixing pin 22. A torsion spring 23 is sleeved on the fixing pin 22. One end of the torsion spring 23 is fixedly connected to the abutment block 24, and the other end is fixedly connected to the fixing pin 22.

[0036] The accommodating groove 21 provides installation space for the fixing pin 22 and the abutment block 24, so that the abutment block 24 can be accommodated in the accommodating groove during the extension and contraction of the spring ear 2. A friction pattern 25 is fixed to one side of the end of the abutment block 24. Under the torsional force of the torsion spring 23, one side of the end of the abutment block 24 abuts on the inner side of the sleeve at the connection between the watch and the strap 1. The friction pattern 25 at the end of the abutment block 24 increases the friction force between the abutment block 24 and the inner side of the sleeve at the connection between the watch strap, thereby improving the reliability of the quick-release structure.

[0037] When the user needs to remove the watch strap, the abutment block 24 moves during the contraction of the spring ear 2, which overcomes the elastic force of the torsion spring 23 and reduces the contact pressure between the abutment block 24 and the inner side of the sleeve at the connection between the watch strap 1. When the contraction of the spring ear 2 is completed, the abutment block 24 can be accommodated in the accommodating groove 21. Once the external force is removed, the torsion spring 23 will push the abutment block 24 back to its original position and make close contact with the inner side of the sleeve at the connection between the watch strap again, thereby ensuring that the watch strap is fixed in place.

[0038] Figure 7 This is a schematic diagram of the structure inside the limiting cylinder of the pushing component of the present invention. Figure 8 For the present invention Figure 7 The structural schematic diagram enlarged at point B in the middle shows that the watch strap 1 is provided with a pushing component for easy automatic adjustment. The pushing component includes a limiting cylinder 8, which is fixedly inserted into the watch strap 1. The limiting cylinder 8 is connected to the pressing groove 12. A limiting screw 82 is provided at the opening of the limiting cylinder 8. An abutment rod 81 is slidably inserted into the limiting cylinder 8. The abutment rod 81 has a "T"-shaped structure. In a natural state, the end of the abutment rod 81 is in contact with the watch strap button 6. A micro cylindrical airbag 83 is bonded between the abutment rod 81 and the limiting screw 82. The micro cylindrical airbag 83 is located in the limiting cylinder 8, thereby limiting the circumference of the micro cylindrical airbag 83. The limiting screw 82 is screwed to the opening of the limiting cylinder 8, thereby limiting one end of the micro cylindrical airbag 83. One end of the micro cylindrical airbag 83 is fixedly connected to a connecting tube 84.

[0039] Figure 5 This is a schematic diagram of the structure of the push component chute of the present invention. Figure 6 For the present invention Figure 5 In the enlarged structural diagram at point A in the middle, a slide groove 85 is provided on one side of the ear hole 11 of the watch strap 1, a guide rod 86 is fixedly inserted into the slide groove 85, a top block 87 is slidably sleeved on the guide rod 86, a limiting slide bar 88 is provided on one side of the top block 87, one end of the limiting slide bar 88 extends to the depth of the slide groove 85, and limits the micro-block airbag 80 between the top block 87, a micro-block airbag 80 is provided between one side of the top block 87 and the slide groove 85, one end of the micro-block airbag 80 is connected to the connecting tube 84, and the connecting tube 84 connects the micro-cylindrical airbag 83 and the micro-block airbag 80, allowing gas to flow between the two to transmit pressure changes.

[0040] A return spring 89 is provided on one side of the top block 87 on the guide rod 86. In the pressed state, one end side of the top block 87 is in contact with the end step of the spring ear 2. The elastic force of the return spring 89 can overcome the air pressure of the micro-sleeve airbag 80 and the micro-cylindrical airbag 83 in the natural state. The elastic force provided by the return spring 89 is much smaller than the elastic force of the spring ear spring 3. The models of the micro-cylindrical airbag 83 and the micro-sleeve airbag 80 can be selected according to actual working conditions.

[0041] When the user presses the strap button 6 on the strap 1, the end of the strap button 6 moves toward the pressing groove 12, and the end surface of the strap button 6 pushes the abutment rod 81 to move. The micro cylindrical airbag 83 is compressed by the squeezing force of the abutment rod 81, so that the gas in the micro cylindrical airbag 83 is transmitted to the micro sleeve airbag 80 through the connecting tube 84. The micro sleeve airbag 80 is expanded by the gas and squeezes the top block 87 to slide along the guide rod 86, and the limit slide 88 also slides accordingly. The top block 87 is in the slide groove 85. During the upward movement, the step of the ear 2 is further pushed to move, so that the ear 2 moves toward the pressing spring 5, further ensuring the smooth contraction of the ear 2 and avoiding the loss of the elastic force of the ear 2 pushing the spring 5 due to the service life limit of the ear spring 3; when the user stops pressing the strap button 6, the elastic force of the reset spring 89 will push the top block 87 back to its original position, the pressing spring 5 presses against the slot of the strap button 6, and the entire pushing assembly returns to its natural state, ready for the next operation.

[0042] Figure 9 This is a schematic diagram of the structure inside the protruding seat of the present invention. Figure 10 For the present invention Figure 9 In the enlarged structural diagram at point C, a slot 61 is provided on one side of the strap button 6, and a limit assembly is provided on the strap 1. The limit assembly includes a protruding seat 7, which is located on one side of the pressing groove 12 and is fixed to the strap 1. A groove 71 is provided on the protruding seat 7, and a mounting circular plate 72 is provided at the opening of the groove 71. The mounting circular plate 72 is fixed to the protruding seat 7 by screws, and the protruding seat 7 is made of a hard material.

[0043] A pulling rod 73 is slidably inserted into the mounting circular plate 72, and an insert block 75 is fixedly connected to the end of the pulling rod 73. The insert block 75 has a "T"-shaped block structure, and the end has an inclined surface structure. The end of the insert block 75 is correspondingly arranged with the slot 61, and a support spring 74 is sleeved on the pulling rod 73. The model of the support spring 74 can be selected according to the actual working conditions.

[0044] When the user presses the strap button 6 on the strap 1, one side of the strap button 6 contacts the inclined surface of the insert block 75 and slides relative to it. When the end of the insert block 75 corresponds to the slot 61 on the strap button 6, the elastic force of the support spring 74 pushes the end of the insert block 75 to move outward, and then the end of the insert block 75 is inserted into the corresponding slot 61, thereby locking the position of the strap button 6, making it easier for the strap button 6 to be pressed so that the end of the ear 2 can stably complete the contraction action without continuous pressing, which is convenient for the user to perform other operations; when installation is required, only the pulling rod 73 needs to be pulled, the support spring 74 is compressed, and the insert block 75 is separated from the slot 61. Under the elastic force of the pressing spring 5, the pressing spring 5 presses the slot of the strap button 6 to restore the initial state.

[0045] During actual installation, when the strap button 6 is pressed, the ear spring 3 pushes the ear 2 toward the pressing spring 5, shortening the length of the ear 2 extending out of the strap nut 4, completing the contraction of the ear 2. At the same time, one side of the strap button 6 contacts the inclined surface of the plug 75 and slides relative to it. When the end of the plug 75 corresponds to the slot 61 on the strap button 6, the elastic force of the support spring 74 pushes the end of the plug 75 to move outward, and then the end of the plug 75 is plugged into the corresponding slot 61, realizing the position locking of the strap button 6, making it easier for the strap button 6 to press the ear 2 The end of the strap can stably complete the contraction action without continuous pressing, which is convenient for the user to perform other operations. At the same time, when the user presses the strap button 6 on the strap 1, the end of the strap button 6 moves toward the pressing groove 12, and the end surface of the strap button 6 pushes the abutment rod 81 to move. The micro cylindrical airbag 83 is compressed by the squeezing force of the abutment rod 81, so that the gas in the micro cylindrical airbag 83 is transmitted to the micro sleeve airbag 80 through the connecting tube 84. The micro sleeve airbag 80 is expanded by the gas and squeezes the top block 87 to slide along the guide rod 86. The limit slide 88 also slides accordingly, and the top block 87 moves on the slide groove 85 During the contraction of the ear 2, the abutment force of the abutment block 24 overcomes the elastic force of the torsion spring 23 and moves, reducing the contact pressure between the abutment block 24 and the inner side of the sleeve at the connection between the abutment block 24 and the strap 1, so that the contraction of the ear 2 is completed and the abutment block 24 can be accommodated in the accommodating groove 21, and then the ear on the strap 1 is aligned with the dial hole. When the user stops pressing the strap button 6, the pulling rod 73 is pulled, the supporting spring 74 is compressed, and the insert block 75 is separated from the slot 61. Under the elastic force of the pressing spring 5, the pressing spring 5 presses against the slot of the strap button 6 to restore the initial state. In the natural state, the inclined surface of the strap button 6 presses against the inclined surface of the ear 2, so that the ear 2 moves outward toward the ear hole 11, completing the extension of the ear 2. Once the external force is removed, the torsion spring 23 pushes the abutment block 24 back to its initial position, and again contacts the inner side of the sleeve at the strap connection, thereby ensuring that the strap is fixed in place, thereby facilitating the quick installation of the ear.

[0046] When the user presses the strap button 6 on the strap 1, one side of the strap button 6 contacts the inclined surface of the insert block 75 and slides relative to it. When the end of the insert block 75 corresponds to the slot 61 on the strap button 6, the elastic force of the support spring 74 pushes the end of the insert block 75 to move outward, and then the end of the insert block 75 is inserted into the corresponding slot 61, thereby locking the position of the strap button 6. At the same time, the ear spring 3 pushes the ear 2 toward the pressing spring 5, shortening the length of the ear 2 extending out of the strap nut 4, completing the contraction of the ear 2. In this process, the end of the strap button 6 moves toward the pressing groove 12. The end surface of the watchband button 6 pushes the abutment rod 81 to move, and the micro cylindrical airbag 83 is compressed by the squeezing force of the abutment rod 81, so that the gas in the micro cylindrical airbag 83 is transmitted to the micro sleeve airbag 80 through the connecting tube 84. The micro sleeve airbag 80 is expanded by the gas and squeezes the top block 87 to slide along the guide rod 86, and the limiting slide 88 also slides accordingly. In the process of moving the top block 87 on the slide groove 85, it further pushes the step of the raw ear 2 to move, so that the raw ear 2 moves toward the pressing spring 5, further ensuring the smooth contraction of the raw ear 2 and avoiding the service life limiting factor of the raw ear spring 3 and the loss of the elastic force of the raw ear 2 pushing the raw ear 2 toward the pressing spring 5.

[0047] While embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions, and variations may be made to these embodiments without departing from the principles and spirit of the invention, and that the scope of the invention is defined by the appended claims and their equivalents.
