Description

Technical Field

[0001] The invention relates to the technical field of quartz watches, in particular to a quartz electronic watch with improved precision. Background Art

[0002] A quartz watch, also known as a quartz vibration electronic watch, is a type of wristwatch. When a quartz crystal is affected by battery power, it will produce regular vibrations. The vibration frequency of a quartz crystal is as high as 32,768 times per second. People can design a simple circuit to count the number of vibrations. When it counts to 32,768 times, the circuit will send a message to let the second hand move forward one second. Compared with mechanical watches, quartz watches have a lower error rate due to their stable vibration frequency. They are also popular among the general public because of their simple structure and low cost. The quartz crystal and the circuit board inside the existing quartz watch are fixed by welding with wires. Then, after the battery provides a specific voltage to the integrated circuit, the quartz resonator is started to vibrate through the oscillation circuit and the quartz resonator therein to form an oscillation circuit source; an alternating bidirectional pulse signal is formed, thereby driving the stepping motor to rotate intermittently, and further driving the transmission gear train, so that the watch hands can accurately display the time. However, the welding method is more troublesome to install and disassemble during subsequent maintenance, and requires professional personnel to operate. It is easy to cause damage during subsequent maintenance, resulting in insufficient accuracy in the later stage. In addition, the influence of temperature on the quartz crystal needs to be avoided during the welding process, which causes inaccurate accuracy in the subsequent stage.

The vibration frequency of the quartz body 403 in one second is fixed, thereby pushing the vibration frequency to the circuit board 402, and then the needle plate mechanism 3 is rotated.

A disassembly hole 506 is provided at one end of the disassembly seat 503 close to the fixed block 504. The disassembly hole 506 is adapted to the diameter of the fixed block 504. A line hole 507 is provided at the top of the clamping rod 502. The line hole 507 is adapted to the connecting line 404. A limiting groove 508 is provided inside the disassembly seat 503 at the disassembly hole 506. A first spring 509 is fixedly connected inside the limiting groove 508. The limiting groove 508 The plug-in block 510 is slidably connected inside, and the plug-in block 510 contacts the fixed block 504; the inner side of the fixed block 504 is fixedly connected with the circuit chip 10, and the circuit chip 10 contacts the end of the connecting wire 404, and the plug-in block 510 is fixedly connected with the tin block 11 on the side close to the fixed block 504; after the connecting wire 404 passes through the line hole 507, the disassembly seat 503 is pushed to squeeze the first spring 509 and the plug-in block 510. Since the fixed block 504 is conical, It slides to between the fixed block 504 and the limit block 505 to engage, and then the first spring 509 pushes out the plug-in block 510, allowing the connecting wire 404 to contact the tin block 11, forming a circuit signal connection, completing subsequent use, and continuing to push during disassembly to allow the plug-in block 510 to be located behind the limit block 505. Since the limit block 505 slides on the engaging rod 502, the limit block 505 is moved to the fixed block 504, and then it is detached along the cone, making disassembly convenient.

[0020] Combination Figure 5 The locking mechanism 6 includes a locking groove 601, a second spring 602, a first clamping plate 603 and a second clamping plate 604.

The second clamping plate 604 is slidably connected to the inside of the locking groove 601 through the second spring 602. The first clamping plate 603 and the second clamping plate 604 are in contact with the connecting line 404, and the second spring 602 squeezes the second clamping plate 604 so that the connecting line 404 can be fixed and stored.

[0021] Combination Figure 2 The bottom shell 7 is rotatably connected to the side of the shell body 1 with a connecting rod 8, and the top of the disassembly seat 503 is fixedly connected to the I-shaped piece 9.

[0022] Working principle: during installation, the second spring 602 is pressed against the second clamping plate 604 to allow the connecting wire 404 to pass through and be fixed. After the connecting wire 404 passes through the line hole 507, the disassembly seat 503 is pushed to press the first spring 509 and the plug-in block 510. Since the fixing block 504 is conical, it slides to the fixing block 504 and the limit block 505 for engagement. Then the first spring 509 pushes the plug-in block 510 out to allow the connecting wire 404 to contact the tin block 11. Then the connecting rod 8 and the I-shaped piece 9 in the bottom shell 7 are installed, and the bottom shell 7 is inserted into the shell 1. The connecting rod 8 rotates the I-shaped piece 9 to drive the disassembly seat 503 to move, ensuring that the connecting wire 404 is in close contact with the circuit chip 10. During disassembly, the bottom shell 7 is taken out, and then the connecting rod 8 is separated, and then the push is continued to allow the plug-in block 510 to be located behind the limit block 505. Since the limit block 505 slides on the locking rod 502, the limit block 505 is moved to the fixed block 504, and then the disassembly seat 503 is pushed. As the cone is detached, the connecting line 404 can be peeled off to facilitate disassembly.
