Detailed Description
The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
The length adjustment of many watches among the prior art is very complicated difficult, just need use instrument and corresponding skill just can be more smooth dismantlement some section watchband joint piece for the length adjustment of steel watchband, also need very careful operation during the dismantlement to avoid the deformation damage of spare part, therefore very inconvenient.
The following is a preferred embodiment of the present invention for providing a quartz watch with an adjustable wrist strap that solves the above technical problems.
As the tuning fork will vibrate regularly, it will also vibrate regularly when the quartz crystal is affected by the battery power. The vibration frequency of the quartz crystal per second reaches 32768 times, a simple circuit can be designed to calculate the vibration frequency of the quartz crystal, and when the vibration frequency reaches 32768 times, the circuit transmits a message to enable the second hand to move forward for one second.
Because the vibration of quartz is fairly regular, even with inexpensive quartz watches, the error rate within a day will not exceed 1 second. The quartz watch can also be called a "quartz oscillator type electronic timepiece" because it utilizes the "oscillation phenomenon" of the quartz plate. When the quartz receives external stress voltage, the quartz has the properties of deformation and expansion, and conversely, if the quartz is compressed, electric power is generated at two ends of the quartz; such properties are also seen on many crystalline bodies, known as the "piezoelectric effect".
The quartz watch is a crystal which utilizes periodic continuous 'vibration' and brings accurate time for people. Firstly, the quartz plate in the quartz watch is electrified, and the quartz can correctly vibrate at the frequency of 32768 Hz; this frequency must then be changed to a signal current frequency of 1Hz (one change in current over one second). The amplitude of the signals is increased (because the current generated by vibration is weak), the rotor gear is started by the signal current, and the second hand of the watch is started. Then, the minute hand and the hour hand jump are related to the principle of mechanical structure, such as: when the second hand jumps by 60, the minute hand jumps by one.
All quartz watches are equipped with a battery. It provides power to an integrated circuit and a quartz resonator, vibrating 32768 times per second. The integrated circuit is the "brain" of the watch. It controls the vibration of the quartz resonator and acts as a frequency divider. 32768 oscillations were divided in half 15 times to achieve one pulse per second. With the "raw material" for one second, the timepiece can be driven.
The quartz watch comprises a quartz resonator, a CMOS integrated circuit, a stepping motor, a power supply and a pointer;
the quartz resonator is an artificial quartz crystal, formed by cutting in a certain form, and the positive and negative electricity of the quartz resonator are connected with electronic circuits, so that the quartz resonator can be used as a basic quartz oscillator and becomes a time reference of a clock.
The CMOS integrated circuit is one of the most important parts in the quartz watch, which has extremely high requirements for the elegance of the watch, and thus a special CMOS integrated circuit must be provided.
In the well-known pointer type quartz watch, a stepping motor is used as a transducer to drive a pointer to point to relevant time through relevant complex operation.
The power supply is used for supplying power to the quartz resonator, the CMOS integrated circuit and the stepping motor.
Prior art quartz watches are often configured with steel band watches for wearing by the user.

Referring to FIG. 3, FIG. 3 is a diagram of a second length-adjusting structure of the watch band of the quartz watch with the adjustable watch band of the present invention.
In the present invention, the length adjustment of the band 12 can take various forms, and when the length is required to be the longest, all the rotation shafts 23 can be connected to the second connection positions of the connection units 22, as shown in fig. 2;
on the other hand, because the length of the band 12 to be adjusted varies under different conditions, in order to seek beauty and comfort, when the length of the band 12 is adjusted, a plurality of adjacent connecting monomers 22 can be combined into a chain group, each chain group comprises two or more connecting monomers 22, and the number of the connecting monomers on the chain group can be selected according to specific requirements;
the state shown in fig. 2 can also be regarded as a chain set comprising one linking monomer 22.
When the distance between the adjacent chain groups is adjusted to be the second set distance, the first set distance is kept between the adjacent connecting monomers 22 on each chain group, so that the structure of the whole watchband 12 is more uniform and the watchband is more comfortable to wear.
On the other hand, it should be further noted that, adjacent connecting single bodies 22 are not only adjustable from the first set distance to the second set distance, when one rotating shaft 23 of two adjacent connecting single bodies 22 is connected to the second connecting position of the corresponding connecting single body 22, and the other rotating shaft 23 is connected to the first connecting position of the corresponding connecting single body 22, the distance between the two connecting single bodies 22 is an intermediate value between the first set distance and the second set distance, that is, two distance levels with selectable adjustment are provided between the adjacent connecting single bodies 22.
In addition, the length of the connecting units 22 varies, and here, if the length of the connecting unit 22 is less than 16mm, the adjustable distance between the adjacent connecting units 22 is approximately between 2mm and 10 mm.
The working principle of the invention is as follows: taking the difference value between the first set distance and the second set distance as a first adjusting distance, and taking the difference value between the first set distance and a middle value or the difference value between the second set distance and the middle value as a second adjusting distance;
when the length of the watchband needs to be adjusted, how many first adjustment distances or how many second adjustment distances need to be adjusted are calculated according to the total length of the watchband 12 to be adjusted, the adjustable length range between the adjacent connection single bodies 22 and the number of the connection single bodies 22 on the watchband 12, and then how many adjacent connection single bodies 22 need to be combined into a chain group can be calculated.
The operation of specifically adjusting the distance between two adjacent connection units 22 is as follows:
if the rotating shafts 23 at the two ends of one connecting unit 22 need to be switched from the first connecting position to the second connecting position in a sliding manner, the fixing members 21 at the two ends of the connecting unit 22 need to be forced to rotate outwards relative to the connecting unit 22;

If the rotating shafts 23 at the two ends of one connecting unit 22 need to be switched from the second connecting position to the first connecting position in a sliding manner, the fixing members 21 at the two ends of the connecting unit 22 need to be forced to rotate inwards relative to the connecting unit 22;
when the fixing member 21 and the connecting unit 22 rotate to be in limit contact with each other or are about to be in limit contact with each other, the unlocking member 26 is located at or close to the third rotation position, and the limiting member 24 is located at or close to the second sliding position, at this time, an external force can be gradually applied to pull the rotating shafts 23 at the two ends from the second connection position to the first connection position;
in the process that the rotating shaft 23 slides from the second connection position to the first connection position, along with the second extrusion convex portion 262 or the rotating shaft 23 no longer extrudes the limiting member 24, the limiting member 24 gradually slides from the second sliding position to the first sliding position under the elastic force action of the spring 25, and when the rotating shaft 23 slides to the first connection position, the limiting member 24 is located at the first sliding position, so as to limit the rotating shaft 23 located at the first connection position, and thus the rotating shaft 23 is stably and rotatably connected to the first connection position.
If the rotating shafts 23 at the two ends of one connecting unit 22 are located at the first connecting position, and the rotating shaft 23 at the left end needs to be switched to the second connecting position in a sliding manner from the first connecting position, and the rotating shaft 23 at the right end needs to be kept at the first connecting position, the fixing members 21 at the left end and the right end of the connecting unit 22 need to be forced to rotate outwards relative to the connecting unit 22, so that the limiting members 24 at the two ends can be extruded, and uniform pressure is formed on the spring 25;
when the fixing member 21 and the connecting unit 22 rotate to be in limit contact with each other or are about to be in limit contact with each other, the unlocking members 26 at both ends are located at or close to the second rotation position, and the limiting member 24 is located at or close to the second sliding position;
at this time, an external force can be gradually applied to pull the rotating shaft 23 at the left end from the first connection position to the second connection position, and simultaneously, the unlocking piece 26 at the right end gradually rotates from the second connection position to the first connection position, so that the first extrusion convex part 261 gradually keeps away from the limiting piece, and the extrusion on the limiting piece 24 is released until the rotating shaft 23 at the left end slides to the second connection position, and the unlocking piece 26 at the right end rotates to the first connection position, so that the limiting pieces 24 at the two ends can synchronously slide from the second sliding position to the first sliding position, and simultaneously, the rotating shaft 23 at the left end is stably connected to the second connection position, and the rotating shaft 23 at the right end is stably connected to the first connection position.
Similarly, if the rotating shafts 23 at the two ends of one connecting unit 22 are respectively located at the first connecting position and the second connecting position, and when one or two of the two rotating shafts 23 need to slide to switch positions, the fixing members 21 at the two ends need to rotate to drive the two limiting members 24 to slide to the second sliding position, and then the rotating shafts 23 at the two ends need to slide synchronously, so as to synchronously release the extrusion on the corresponding limiting members 24, or the rotating shaft 23 at one end slides while being matched with the unlocking member 262 at the other end to rotate to synchronously release the extrusion on the corresponding limiting members 24, so that the limiting members 24 at the two ends can synchronously slide from the second sliding position to the first sliding position, and the detailed description of the specific process is omitted here.
This completes the band adjustment process of the quartz watch with the adjustable wrist band of the preferred embodiment.
