Referring to fig. 1 to 4, the present embodiment provides a wristwatch including a housing mechanism, a shield member, a movement member, and a dial member, and the connection relationship and the operation principle of these components will be described in detail below.

The accommodating mechanism may be formed with an accommodating portion. Specifically, as shown in fig. 1, fig. 1 shows a schematic view of a cross-sectional view of a first angle of view of a wristwatch, and in this schematic view, the entire structure of the housing mechanism is schematically given, and the structure of the movement and the like is omitted. The accommodating mechanism may include the pressing member 10, the body member 30, the support member 34, and the bottom cover member 70, and the members included in the accommodating mechanism will be described in detail below in conjunction with the shielding member 20 and the moving member 40, respectively.

In an embodiment, the shielding member 20 may be formed in the shape of a ring with the central axis (i.e. the predetermined axis) as the axis shown in fig. 1, see fig. 2, the shielding member 20 comprises a first side portion 21 and a second side portion 22 facing away from each other, where "facing away" means that the aforementioned two side portions are oriented oppositely or substantially oppositely. In fig. 2, it is apparent that the second side portion 22 faces generally upward, while the first side portion 21 faces downward. Further, the height of the radially inner side of the second side portion 22 is lower than the height of the radially outer side of the second side portion 22 in the horizontal direction, the second side portion 22 may be further configured as an inclined surface, and the dial member 80 may be provided at a hole portion defined by the annular shielding member 20 and connected with the shielding member 20, see especially fig. 1 herein, so that the inclined arrangement of the second side portion 22 is especially advantageous for making the display structure stand out when the edge of the dial member 80 is provided with the display structure such as a projecting member representing time.

On this basis, the shielding member 20 may be formed with a plurality of cutaway portions 27, and the cutaway portions 27 may be configured so that objects in the environment below the shielding member 20 can be observed when the shielding member 20 is observed above, and therefore, the cutaway portions 27 may be formed as through holes that are relatively easy to machine, as an advantageous option. When the second side portion 22 of the shielding member 20 is viewed from above, at least some of the plurality of through-holes (e.g., all of the plurality of through-holes) may be evenly distributed on a predetermined circle having a center at a predetermined point, which may be passed by the central axis. The function of the arrangement of the plurality of through holes will be explained in the following description, and the mounting manner of the shielding member 20 will be described in detail below.

As shown in fig. 2, a third cylindrical surface 23 may be formed between the first side portion 21 and the second side portion 22 of the shield member 20, the third cylindrical surface 23 being located on the outer side in the radial direction of the shield member 20, the third cylindrical surface 23 may be formed with a second annular protrusion 24 protruding with respect to the third cylindrical surface 23, and a lower end of the second annular protrusion 24 and a lower end of the third cylindrical surface 23 may each be defined by a second annular surface 25. Based on the structure of the foregoing shielding member 20, the pressing member 10 and the body member 30 described below may be configured as follows.

Specifically, the pressing member 10 may be formed with a first cylindrical surface 11 having a central axis as an axis, and with continued reference to fig. 2, it is apparent that a space defined by the first cylindrical surface 11 is formed as a part of the above-described accommodating portion, a lower end of the first cylindrical surface 11 may be defined by a pressing end surface 12, and the pressing end surface 12 may be further formed with a first annular protrusion 13 protruding from the pressing end surface 12. The body member 30 may be formed with a first annular surface 31 having a central axis as an axis, and a radially outer side of the first annular surface 31 may be defined by a second cylindrical surface 32. Thereby, still referring to fig. 2, the second annular protrusion 24 may be urged against the first annular surface 31 via the pressing end surface 12, and further such that the first annular protrusion 13 is located between the second annular protrusion 24 and the second cylindrical surface 32, and a first gap is formed between the third cylindrical surface 23 and the first cylindrical surface 11.

In an embodiment, the first gap may be formed as 50C ("C" here is a unit of measurement "wire" common in the mechanical field, 1 hundredth of a millimeter), which gap precision firstly ensures the feasibility of the compression member 10 being able to be inserted between the second cylindrical surface 32 and the third cylindrical surface 23 to obtain an assembly, and in the assembled state also avoids the poor friction between the first cylindrical surface 11 and the third cylindrical surface 23, and at the same time, as a watch for precision machines, such gap precision is particularly advantageous in preventing the intrusion of possible foreign bodies. And the first annular protrusion 13 is located between the second annular protrusion 24 and the second cylindrical surface 32, the fitting area of the pressing member 10 and the second cylindrical surface 32 can be increased to increase the stability of the pressing member 10.

In an embodiment, the shield member 20 may be further positioned as follows. As shown in fig. 3, the shielding member 20 may further include a first positioning portion 26 disposed on the second annular surface 25, the first positioning portion 26 may be formed as a positioning column, and correspondingly, the first annular surface 31 may be formed with a second positioning portion 33, the second positioning portion 33 may be formed as a positioning groove matched with the positioning column, and in a state where the second annular protrusion 24 is pressed against the first annular surface 31 by the pressing end surface 12, the first positioning portion 26 and the second positioning portion 33 may be matched with each other to prevent the rotational movement of the shielding member 20 around the central axis, so as to achieve the positioning, and as a result, the positioning is effectively matched with the installation manner of the shielding member 20, and the shielding member 20 is ensured to be installed in a precise manner. Alternatively, the first positioning portion 26 and the second positioning portion 33 may be provided in positions corresponding to the 3 o 'clock of the wristwatch, so that the view shown in fig. 3 shows a view of the wristwatch sectioned by a plane passing through both the 3 o' clock position and the central axis. The second adjusting mechanism 60 is also shown in the drawing, and the second adjusting mechanism 60 is used for adjusting the time of the watch, and may include a vertical gear 51, a clutch wheel and other members, and adjust the time of the watch in an operation manner in the prior art, which is not described in detail herein.

On the basis of the above-described features, still referring to fig. 2, the moving member 40 may be disposed below the above-described shielding member 20, and may also be formed in an annular shape with the central axis as an axis. The movement member 40 may further include a third side portion 41 and a fourth side portion 42 facing away from each other, the fourth side portion 42 is close to the first side portion 21 relative to the third side portion 41, that is, the fourth side portion 42 is located above, the third side portion 41 is located below, a second gap is formed between the fourth side portion 42 and the second annular surface 25, and the second gap may be formed to have a precision of 5C, and 5C, which particularly ensures stable rotation of the movement member 40, because when the gap size is greater than 5C, the movement member 40 will have a large shake during rotation, which particularly may affect precision of assembly and operation of other members of the watch, and when the gap size is less than 5C, the movement member 40 will be difficult to rotate smoothly, and a jam or even a dead jam will occur. The third side portion 41 located below may be further formed with a transmission portion that can be driven to rotate the moving member 40 about the central axis, and alternatively, the transmission portion may be formed as a ring gear 44 that can be driven by a gear 51 in a first adjustment mechanism 50 described below, which will be described in detail later in the description.

With reference to fig. 2 to 4, the support member 34 may be used to support the third side portion 41, thus achieving support of the moving member 40. The support member 34 may be formed as an annular wall structure and its upper end may be formed with a radially inward annular flange to increase the support area for improved stability of the support. A groove portion 35 may be formed between the support member 34 and the body member 30, and the gear 51 of the first adjustment mechanism 50 may be received in the groove portion 35. As a preferred embodiment, the support member 34 may be integrally formed with the body member 30.

On the basis of the above-described features, the fourth side portion 42 of the moving member 40 is formed with a plurality of identification structures, at least one of which can be exposed through at least one of the plurality of through holes when the shielding member 20 is viewed above the shielding member 20 when the moving member 40 performs the rotational movement in the above-described manner. As a preferred embodiment, which will be described in detail below, the recognition structure may include a plurality of sets of recognition members 43, the plurality of sets of recognition members 43 being sequentially exposed through the aforementioned through-holes. Further, the identification structure referred to herein means a structure whose presence can be observed and determined by observation of a person, and for the plurality of groups of identification members 43, it may be configured such that each group of identification members 43 can be identified at least by the person to be distinguished from the other groups of identification members 43, and for example, each group of identification members 43 may be formed as a structure formed of a diamond material obtained by a different cutting manner, or may be formed of a different color as a distinguished diamond material.

In an embodiment, the above-mentioned plurality of groups of identification members 43 may be defined as n groups of identification members, and the n groups of identification members may be further defined as i-th group of identification members, respectively, and the i-th group of identification members may include m i-th identification members. The i-th group of identification members includes the i-th identification member in order j, and among the n-th group of identification members, all the i-th identification members in order j are arranged in sequence at equal intervals in the circumferential direction of the above-mentioned predetermined circle (i.e., when viewed above the moving member 40) so that the circumference of the predetermined circle is equally divided. On this basis, it may be defined that the number distributed in the above-described through holes is formed in m, the m through holes are arranged such that, at the initial position of the n groups of identification members, the m ith identification member is exposed through the m through holes respectively to form an exposed state, and the i +1 th group identification member to the nth group identification member sequentially undergo the exposed state when the motion member 40 rotates. The values of the aforementioned quantities may be: n is greater than or equal to 2, i is greater than or equal to 1 and i is less than or equal to n, m is greater than or equal to 2, j is greater than or equal to 1 and j is less than or equal to m, and n, i, m and j are integers.

It is particularly preferred that n may be equal to 4, m may be equal to 12, the positions of the 12 through holes corresponding to 1 hour to 12 hours of the watch, respectively. Therefore, the plurality of identification structures include first to fourth groups of identification members, 12 first identification members of the first group of identification members may be exposed through 12 through holes, respectively, in the initial position, 12 second identification members of the second group of identification members may be exposed through 12 through holes, respectively, when the moving member 40 rotates, and so on, and when the fourth group of identification members is in the exposed state, the moving member 40 is caused to return to the state in which the first group of identification members is in the exposed state by the continued movement of the moving member 40, thus realizing the process of cyclic switching of the four groups of identification members.

It is apparent that the first to fourth groups of identification members include 48 identification members in total, and thus the angle between each two adjacent identification members is 7.5 degrees, that is, in the exposed state of one group of identification members, the motion member 40 is rotated by 7.5 degrees to switch to the exposed state of the other group of identification members adjacent to the one group of identification members. The four groups of identification members may be mounted, for example, in a clockwise direction, by first mounting a first identification member, mounting a first second identification member at an interval of 7.5 degrees, then mounting a first third identification member at an interval of 7.5 degrees, then mounting a first fourth identification member at an interval of 7.5 degrees, and then further mounting a second first identification member to a second fourth identification member on the basis until all the identification members are mounted.

According to the above-described features, in the embodiment, the first adjustment mechanism 50 may be provided to the body member 30, and include an adjustment portion exposed to an outer side portion of the body member, and a fitting portion located in the housing portion, and the fitting portion may include the gear 51, and the adjustment portion may be used to screw to rotate the gear 51, and thus drive the ring gear 44 to rotate, so that the moving member 40 rotates. As an advantageous embodiment, the ring gear 44 may be formed with 3100 threads in diameter, the ring gear 44 may be formed with 106 teeth, the gear 51 may be formed with 350 threads in diameter, and 10 teeth may be formed, which is particularly advantageous in smooth meshing between the gear 51 and the ring gear 44.

The above description is only a preferred embodiment of the present application, and not intended to limit the scope of the present application, and all changes that can be made in the details of the present application and the equivalents thereof, or directly or indirectly applied to other related technical fields, without departing from the spirit of the present application are intended to be embraced therein.
