Detailed Description

The technical solution in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention.

Please refer to fig. 1 to fig. 6, which are schematic structural views of a watch band 100 according to a first embodiment of the present invention. As shown in fig. 1, the band 100 includes a plurality of unit segments 10 connected in sequence. As shown in fig. 2 and 3, the unit section 10 is provided with a connecting portion 101 and a connecting groove 102, and the connecting portion 101 is connected to the connecting groove 102 on another adjacent unit section 10 by the connecting mechanism 1. Through the connecting mechanism 1, the assembly and disassembly between two adjacent unit sections 10 can be realized.

Two blind holes 120 which are arranged oppositely are arranged on the connecting groove 102; the connecting portion 101 is provided with a T-shaped receiving cavity 110, and the receiving cavity 110 has a first opening 11a and two opposite second openings 11 b. The connecting mechanism 1 is disposed in the accommodating cavity 110, so as to ensure a simple overall appearance of the unit section 10 and avoid dust accumulation.

As shown in fig. 2, the connection mechanism 1 includes a button assembly 1a and two ejector pin assemblies 1b symmetrically disposed at both sides of the button assembly 1 a. The two ejector pin assemblies 1b are used for being correspondingly matched with the two blind holes 120, and the button assembly 1a is used for driving the two ejector pin assemblies 1b to move so as to realize assembly and disassembly.

The button assembly 1a includes a button 11 and a first spring 12 connected to the button 11. The button 11 is slidably disposed at the first opening 11 a. Two guide surfaces 111 are symmetrically arranged on the button 11, and the two guide surfaces 111 are respectively located at two sides of the button 11 and can be respectively correspondingly matched with the two ejector pin assemblies 1b to realize the actions of the two ejector pin assemblies 1 b. The two ends of the guide surface 111 are respectively a locking part 111a and a detaching part 111b, and the detaching part 111b is close to the outer side of the connecting part 101 relative to the locking part 111 a; the two guide surfaces 111 may be such that the button 11 at the position where the distance between the two locking portions 111a is greater than the distance between the two detaching portions 111b is substantially isosceles trapezoid. In this embodiment, the guiding surface 111 is preferably a straight inclined surface to facilitate processing and preparation, but in other embodiments, the guiding surface 111 may also be a curved surface, such as a convex arc surface or a concave arc surface structure.

The thimble assembly 1b comprises a thimble 13 and a second spring 14, the thimble 13 is slidably disposed in the second opening 11b, and the sliding direction of the thimble 13 is perpendicular to the sliding direction of the button 11; the thimble 13 has opposite guide and plug ends 131 and 132. The guiding end 131 can be correspondingly abutted and matched with the guiding surface 111, and the inserting end 132 can be correspondingly inserted into the blind hole 120. When the button 11 slides, the guiding end 131 can move along the guiding surface 111, so that the two ejector pins 13 move close to or away from each other, and the plugging end 132 moves out of the blind hole 120 or moves into the blind hole 120. The end surface of the guiding end 131 is preferably a convex arc surface, so that the guiding end 131 is in point contact with the guiding surface 111, and the friction force between the guiding end 131 and the guiding surface 111 is reduced, thereby facilitating the sliding of the guiding end 131 on the guiding surface 111.

As shown in fig. 4, when two adjacent unit sections 10 are connected together, the push button 11 is located at the first position, and at this time, the guide end 131 abuts against the locking portion 111a, and the distance between the two locking portions 111a is relatively large, so that the two ejector pins 13 are located at positions away from each other. The second spring 14 is deformed and provides the ejector pin 13 with an elastic force toward the inside of the second opening 11b, that is, the second spring 14 can provide a force to bring the two ejector pins 13 close to each other. The insertion end 132 is located outside the second opening 11b and is inserted into the blind hole 120 of another unit section 10. The insertion ends 132 of the two ejector pins 13 are respectively located in the two blind holes 120, so that the connecting portion 101 is limited in the connecting groove 102 of the other unit section 10, thereby realizing the assembly connection between the two unit sections 10.

As shown in fig. 5 and 6, when the two unit segments 10 need to be disassembled, the user can push the button 11 to slide the button 11 toward the inside of the first opening 11 a. When the button 11 slides to the second position toward the inner side of the first opening 11a, the first spring 12 deforms and provides an elastic force toward the outer side of the connecting portion 101 to the button 11, so that the button 11 is returned to the first position by the elastic force of the first spring 12, and the use is convenient. The guiding end 131 moves along the guiding surface 111 and abuts against the locking portions 111a, because the distance between the two locking portions 111a is relatively small, the two ejector pins 13 move close to each other under the elastic force of the second spring 14, the inserting end 132 moves into the second opening 11b and is located outside the blind hole 120 of the other unit section 10, at this time, the two ejector pins 13 are both completely retracted into the accommodating cavity 110, and the connecting portion 101 can be moved out of the connecting groove 102 of the other unit section 10, so that the two unit sections 10 are separated. After the user releases the acting force on the button 11, the button 11 can return to the first position under the elastic force of the first spring 12, and the insertion ends 132 of the two ejector pins 13 can extend out of the accommodating cavity 110 again.

Preferably, the button 11 is a long strip shape arranged along the sliding direction of the thimble 13 to facilitate the corresponding matching between the button 11 and the two thimbles 13, and at the same time, the user can press the button 11 with his own nail, so that the width of the button 11 is narrow, thereby avoiding the phenomenon that the button 11 is pressed to cause the disjointing of the unit section 10 due to the mistaken touch.
