Description

Technical Field

[0001] The present application relates to the technical field of timing devices, and particularly to a front ring locking watch case and a watch. Background Art

[0002] During the use of a watch, especially in some specific application scenarios, such as diving, firefighting, underground operations, etc., it may be necessary to carry an oxygen cylinder. Therefore, it is necessary to accurately time the operation time so that the operator can evacuate in time before the oxygen is consumed; or, in daily life, to develop a good habit, a completion time is specified for each thing, and thus a relatively accurate timing is required. The time period of this kind of timing is usually short, ranging from a few minutes to dozens of minutes. However, using the timing of the watch or clock itself often requires a large amount of calculations, which is not conducive to the operation.

[0003] In the related art, a front ring is provided on the case of the watch or clock, and marks are made on the front ring in the form of scales or numbers. The front ring can rotate coaxially with the case; when in use, the zero mark on the front ring is adjusted to align with the pointer (usually align with the minute hand). In this way, it is equivalent to zeroing the minute hand. After the minute hand has passed for a period of time, it will directly indicate the operation time through the mark on the front ring, which facilitates the timing of the operation time.

[0004] However, in the related art, since the front ring needs to rotate to zero the minute hand; therefore, during the operation, the front ring may be accidentally touched and cause the front ring to rotate, resulting in inaccurate timing. Summary of the Invention

[0005] The present application provides a front ring locking watch case and a watch to solve the technical problem that the front ring of the watch in the related art is prone to rotate due to accidental touch, resulting in inaccurate timing.

[0006] According to the first aspect of the present application, a front ring locking watch case is provided, including:

[0007] A body having a first end face for observing time;

[0008] A front ring provided on the body and located at the first end face. The front ring is rotatably connected to the body coaxially. The front ring is used to cooperate with the watch hands to achieve time period timing; the bottom surface of the front ring has a plurality of positioning portions, and the plurality of positioning portions are arranged along the circumferential direction of the front ring;

[0009] A stop assembly provided on the body and movably connected to the body. The stop assembly is located on one side of the front ring; the top end of the stop assembly abuts against the positioning portion to position the front ring;

[0010] A locking member is provided on the body and is movably connected to the body. The locking member is located at one end of the stop assembly away from the front ring. The locking member is used to operably abut against the bottom end of the stop assembly so that the top end of the stop assembly limits the rotation of the front ring.

[0011] In a possible design, a receiving cavity is provided on the outer sidewall of the body, and the locking member is movably installed in the receiving cavity. The bottom end of the stop assembly extends into the receiving cavity.

[0012] In a possible design, the locking member includes a first part and a second part. The first end of the first part is hinged to the body, the second part is provided on the first part, and the second part is located between the first part and the body. The second part abuts against the bottom end of the stop assembly.

[0013] In a possible design, the locking member further includes a third part. The third part is located at the second end of the first part, and the third part protrudes from the receiving cavity.

[0014] In a possible design, a guiding surface is provided at the edge of the second part. The guiding surface is used to smoothly transition the bottom end of the stop assembly onto the second part.

[0015] In a possible design, a first channel is provided on the body along the axial direction. The stop assembly includes a stop member and a reset member. The first channel is located on one side of the front ring. The stop member is inserted into the first channel, the reset member is provided in the first channel, one end of the reset member is connected to the stop member, and the other end of the reset member is connected to the inner wall of the first channel. The reset member is used to push the stop member so that the top end of the stop member abuts against the positioning portion.

[0016] In a possible design, the stop member includes a first stop section, a positioning section, and a second stop section. The first stop section is connected to the second stop section through the positioning section. The first stop section abuts against the positioning portion, the positioning section is connected to the reset member, and the second stop section abuts against the locking member.

[0017] In a possible design, the positioning portion includes ratchet teeth. The end of the first stop section is a bevel surface, and the inclination direction of the bevel surface is the same as the inclination direction of the ratchet teeth.

[0018] In a possible design, a positioning groove is formed by recessing the peripheral wall of the second stop section, and the locking member is inserted into the positioning groove.

[0019] According to a second aspect of the present application, a watch is provided, comprising a front ring locking case provided by any possible design method of the first aspect of the present application.

[0020] In the embodiment of the present application, a locking member is provided on the housing, and the locking member is provided at the end of the stopper assembly away from the front ring. After the front ring is calibrated to zero time, the locking member abuts against the bottom end of the stopper assembly, so that the top end of the stopper assembly abuts against the positioning portion; thus, the position of the front ring can be fixed and will not rotate due to misoperation or contact. The accuracy of the timing of the front ring can be guaranteed.

[0036] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the technical solutions in the embodiments of this application will be clearly and completely described below in conjunction with the accompanying drawings in the embodiments of this application. Obviously, the described embodiments are part of the embodiments of this application, rather than all of them. Based on the embodiments in this application, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the scope of protection of this application.

[0037] In the description of the embodiments of this application, the terms "first" and "second" are only used for descriptive purposes and cannot be construed as indicating or implying relative importance or implicitly specifying the quantity of the indicated technical features. Thus, features defined with "first" and "second" may explicitly or implicitly include at least one such feature. In the description of this application, "a plurality" means at least two, such as two, three, etc., unless otherwise specifically defined.

[0038] In this application, unless otherwise clearly specified and limited, the terms "installed", "connected", "connected to", "fixed", etc. shall be construed in a broad sense. For example, it may be a fixed connection, a detachable connection, or integrated; it may be directly connected, or indirectly connected through an intermediate medium, and it may be the internal communication of two components or the interaction relationship between two components, unless otherwise clearly limited. For those of ordinary skill in the art, the specific meanings of the above terms in this application can be understood according to specific circumstances.

[0039] In this application, unless otherwise clearly specified and defined, the first feature being "on" or "under" the second feature may be that the first and second features are in direct contact, or the first and second features are indirectly in contact through an intermediate medium. Moreover, the first feature being "above", "over" and "on top of" the second feature may be that the first feature is directly above or obliquely above the second feature, or merely indicates that the horizontal height of the first feature is higher than that of the second feature. The first feature being "under", "beneath" and "underneath" the second feature may be that the first feature is directly below or obliquely below the second feature, or merely indicates that the horizontal height of the first feature is less than that of the second feature.

[0040] In the description of this application, it should be understood that the orientation or positional relationship indicated by terms such as "inside", "outside", "above", "bottom", "front", "rear", etc. (if any) is based on the orientation or positional relationship shown in the drawings. It is only for the convenience of describing this application and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be construed as a limitation to this application.

[0041] Watches or clocks are not uncommon as timekeeping devices in daily life. Currently, with the popularization of built-in electronic timers in smart mobile terminals, watches have gradually become high-end ornaments. On the one hand, they can function as timekeepers, and on the other hand, they can serve as personalized decorations; therefore, they have become an increasingly popular choice for people's personalized decoration.

[0042] Of course, in addition to being used as decorations and for regular timekeeping, watches also have some functional requirements, such as the display of the calendar, week, etc. Generally, a watch includes a watch body and a watch band; the watch band is connected to the watch body; the watch band is used to fix the watch body to the user's wrist to play a device role and also facilitates the user to observe the time.

[0043] The watch body usually includes a housing and a watch core disposed inside the housing. It can be understood that the watch core can be an electronic timekeeping core. For example, a single-chip microcomputer and a timer are integrated on an integrated circuit board or a printed circuit board (PCB), and a power source (such as a rechargeable battery, a button battery, etc.) is disposed inside the housing to achieve timekeeping. Such an electronic watch core can be provided with a liquid crystal display screen inside the housing, and the liquid crystal display screen is electrically connected to the integrated circuit board or the PCB board, and the time is displayed through the liquid crystal display screen. Of course, it can also be that a driving motor (such as a servo motor, a synchronous motor or a stepper motor) is disposed inside the housing, and a pointer system is connected to the output shaft of the driving motor. The driving motor is electrically connected to the integrated circuit board or the PCB board; the pointer system is driven to rotate by the driving motor to achieve the indication of time.

[0044] Optionally, the watch movement can also be a mechanical movement. For example, it is wound by a mainspring and then drives the pointer system to rotate by gradually releasing the energy accumulated during winding, thereby indicating the time.

[0045] In some possible ways, the energy source of the rechargeable battery can come from charging by a charger, the collection and conversion of solar energy by the watch dial, or even by setting a swinging member inside the case to collect the mechanical energy of the watch during movement or vibration and convert it; of course, there can also be other ways, which are not enumerated one by one in the embodiments of this application.

[0046] In some possible ways, users may often use the watch across regions or time zones; that is to say, users may often need to adjust the time of the watch. To facilitate users in adjusting the time, in the embodiments of this application, a control chip can also be set inside the case, such as setting a central processing unit (CPU), a microcontroller unit (MCU), or a neural network processing unit, etc.; when the user adjusts the time through the time-adjusting handle or button, the control chip can control the rotation of the pointer system as needed, thereby facilitating the user to adjust the time.

[0047] After the watch meets the basic timing function, there may also be a need for timing requirements with specific functions. For example, in diving scenarios, underground operations, firefighting, or disaster relief operations, etc., operators usually need to wear oxygen cylinders. We know that the oxygen that an oxygen cylinder can hold is limited and usually can only maintain the normal breathing of an adult for a few minutes to dozens of minutes. For example, an air respirator with a pressure of 25 MPa generally maintains the normal breathing of an adult for 20 - 25 minutes, and the time that can be maintained during the operation will be shorter. This requires a timing device that can accurately time the operation time.

[0048] Although an ordinary watch can play a role in timing, it is obviously not very suitable in the aforementioned operation scenarios. The reason is that, assuming the current time is 17:36 and the time indicated by the watch hands is 5:36; the operation time is 15 minutes, that is to say, when the time indicated by the watch hands reaches 5:51, the operator must evacuate the operation site to avoid dangerous situations. However, during the operation, the operator obviously does not have extra time to calculate the time indicated by the watch hands, and it is also easy to make mistakes when observing. This can easily lead to the operator missing the best evacuation time and thus dangerous situations occurring.

[0049] In order to facilitate timekeeping and time observation for operators, in the related art, a bezel is provided on the case of a watch, and scales or numbers indicating time are provided on the bezel. The bezel is rotatably connected to the case coaxially. Moreover, a abutting post is provided below the bezel. Usually, the lower surface of the bezel is set as a rough ratchet surface, and a spring is provided on the abutting post. The spring abuts against the case. In this way, when the bezel is rotated in a certain direction, the abutting post compresses the spring. After determining the position of the bezel (for example, aligning the zero position with the minute hand of the pointer), the spring resumes deformation, and the abutting post abuts against the lower surface of the bezel, which can prevent the bezel from reversing.

[0050] That is to say, by setting a zero point on the bezel and adjusting the zero point to align with the minute hand of the pointer; in this way, when the minute hand turns a certain angle, the elapsed time can be directly read through the reading on the bezel.

[0051] Still taking the above operation scenario as an example, when an operator needs to dive or work underground, the available operation duration can be determined according to the pressure of the oxygen cylinder, and the zero point of the bezel is rotated to align with the minute hand of the pointer, which is equivalent to zeroing the minute hand. After the operator starts working, the current operation duration can be directly read from the reading on the bezel so as to be able to evacuate the operation site at any time. This facilitates timekeeping during operation. Of course, the operation scenario is only an example for illustration. The bezel can also be used for timekeeping in other non-operation scenarios (such as answering questions and timing).

[0052] Although the current bezel can facilitate timekeeping for operators in the above operation scenarios. However, in the operation scenarios, various emergencies usually occur, which may cause the bezel to rotate erroneously, resulting in inaccurate timekeeping.

[0053] In view of the foregoing problems, according to the first aspect of the present application, with reference to Figure 1 and Figure 2 as shown, Figure 1 is a schematic diagram of the overall structure of a bezel-locking case provided by an embodiment of the present application, Figure 2 is a cross-sectional view taken along line A-A in Figure 1 An embodiment of the present application provides a bezel-locking case, including:

[0054] A body 100, the body 100 has a first end face 101 for observing time.

[0055] It can be understood that a watch is usually worn on the wrist, and the first end face 101 can be the side away from the wrist after the user wears it. Usually, a watch glass 102 is provided on this side. The watch glass 102 can be made of a transparent or semi-transparent material, such as common plastic mirrors, organic glass, quartz glass or sapphire glass, etc.

[0056] Optionally, with reference toFigure 2 As shown, the main body 100 may further include a middle frame 103, a rear ring 104, and a rear cover 105.

[0057] Among them, the watch glass 102 can be fixed to the middle frame 103 by means of bonding, welding, embedding, etc. The material of the middle frame 103 can be a frame made of stainless steel, gold-plated, silver-plated, or copper-plated; of course, in some possible ways, the middle frame 103 can also be a hard plastic. The rear ring 104 is fixed to one end of the middle frame 103 facing away from the watch glass 102, and the rear ring 104 can be used to fixedly install the rear cover 105.

[0058] Optionally, the watch glass 102, the middle frame 103, the rear ring 104, and the rear cover 105 can be connected in a sealed manner. For example, they can be connected by means of sealant, sealing ring, sealing washer, etc. In this way, it can achieve an effective waterproof effect when diving.

[0059] It can be understood that in the embodiments of the present application, the sealing level can be different according to different waterproof levels. In the embodiments of the present application, no limitation is made in this regard.

[0060] The front ring 200 is disposed on the main body 100 and is located at the first end face 101. The front ring 200 is coaxially rotatably connected to the main body 100. Specifically, referring to Figure 2 As shown, beads can be provided on the side wall at the first end face 101 of the main body 100, and beads are also provided on the inner side wall of the front ring 200. The front ring 200 is coaxially rotatably connected to the main body 100 through the beads.

[0061] Optionally, the bead can be a convex rib protruding and extending from the side wall at the first end face 101 of the main body 100. A groove is formed between the convex rib and the side wall of the main body 100. The bead on the inner side wall of the front ring 200 is embedded into the groove and is slidably connected to the groove. In this way, the front ring 200 can be coaxially rotatably connected to the main body 100.

[0062] In some possible ways, in order to facilitate the assembly of the front ring 200, the upper surface of the bead on the main body 100 can be set as an inclined surface, and the lower surface of the bead on the inner side wall of the front ring 200 can also be set as an inclined surface. In this way, during assembly, the front ring 200 can be directly pressed onto the first end face 101 of the main body 100.

[0063] The front ring 200 is used to cooperate with the watch hands to achieve time period timing.

[0064] Specifically, referring to Figure 1As shown, measurement scales, numbers, or a combination of scales and numbers can be provided on the end face of the front ring 200 (specifically, the end face facing the same direction as the first end face 101). For the ice skates, a zero mark can be provided on the end face of the front ring 200. During specific use, the front ring can be rotated to align the zero mark with the minute hand. In this way, after the minute hand rotates a certain angle, the elapsed time length can be directly read according to the numbers or scales without performing addition or subtraction calculations.

[0065] Optionally, the scales, numbers, or the combination of scales and numbers can be provided on the end face of the front ring 200 in the form of paint printing, engraving, or embossing.

[0066] In some possible examples, to improve the overall texture or aesthetics of the watch, referring to Figure 1 As shown, decorative patterns or textures can also be engraved on the end face of the front ring 200, which can improve the feel and aesthetics of the front ring 200.

[0067] It can be understood that since the front ring 200 can rotate axially relative to the body 100, to facilitate the rotation of the front ring 200 and avoid difficulties in rotation or slipping; in the embodiments of the present application, a plurality of convex ribs, convex points, matte surfaces, or friction surfaces can also be provided on the outer side wall of the front ring 200. This can increase the friction between the front ring 200 and the hand and facilitate the rotation of the front ring 200.

[0068] The bottom surface of the front ring 200 has a plurality of positioning portions 201, and the plurality of positioning portions 201 are arranged along the circumferential direction of the front ring 200.

[0069] Specifically, the positioning portion 201 can be in the form of a groove formed by recessing from the bottom surface of the front ring 200 or a toothed ring, etc.

[0070] The stop assembly 300 is provided on the body 100 and is movably connected to the body 100. The stop assembly 300 is located on one side of the front ring 200; the top end of the stop assembly 300 abuts against the positioning portion 201 to position the front ring 200.

[0071] Specifically, referring to Figure 2 As shown, the stop assembly 300 can be located on one side of the bottom surface of the front ring 200. During specific design or implementation, a pin hole can be formed on the body 100, and the stop assembly 300 can be a pin shaft, which is inserted into the pin hole and can move axially along the pin hole (for example, the pin shaft is pushed to move by an elastic restoring member such as a silicone pad or a sponge block). In this way, when the front ring 200 rotates, the bottom surface of the front ring 200 will push the pin shaft downward, so that the front ring 200 can rotate. When the front ring 200 rotates a certain angle (for example, the angle between two adjacent positioning portions 201); the pin shaft is pushed by an elastic restoring member such as a silicone pad or a sponge block and sinks into the positioning portion 201, thereby positioning the front ring 200.

[0072] It is understandable that, in the embodiment of the present application, the top end of the pin can be a rounded top surface or a top surface with chamfers or rounded corners. In this way, when the front ring 200 is rotated next time, the top end of the pin can be ensured to move out of the positioning portion 201 smoothly.

[0073] The locking member 400 is arranged on the main body 100 and is movably connected to the main body 100. The locking member 400 is located at one end of the stop assembly 300 away from the front ring 200; the locking member 400 is used to operably abut against the bottom end of the stop assembly 300 so that the top end of the stop assembly 300 limits the rotation of the front ring 200.

[0074] Specifically, refer to Figure 2 As shown, in the embodiment of the present application, the locking member 400 can be arranged at one end of the stopper assembly 300 away from the front ring 200, and the locking member 400 can be operably abutted against the bottom end of the stopper assembly 300, so that the locking member 400 can limit the movement of the stopper assembly 300. Thus, the stopper assembly 300 can no longer move downward. In this way, when the front ring 200 is accidentally touched, it will not rotate. That is, after the front ring 200 is calibrated to zero, it will not change again, which can ensure the accuracy of the timing of the front ring 200.

[0075] In some possible examples, the locking member 400 may be rotatably connected to the main body 100; the locking member 400 may specifically be a swing arm disposed on the main body 100, and the swing arm may be moved so as to abut against the bottom end of the stop assembly 300 or leave the bottom end of the stop assembly 300.

[0076] In some other possible examples, the locking member 400 may also be a gear rotatably connected to the body 100 , and the teeth of the gear abut against the bottom end of the stop assembly 300 or leave the bottom end of the stop assembly 300 as it rotates.

[0077] It is understandable that the locking member 400 can also be in the form of a pull-out spring sheet, for example, which can be pushed in to abut against the bottom end of the stopper assembly 300 when it is needed, i.e., after the front ring 200 is zeroed for the minute hand. When the front ring 200 needs to be adjusted, the spring sheet can be pulled out.

[0078] In the embodiment of the present application, by providing a locking member 400 on the housing 100 and providing the locking member 400 at the end of the stopper assembly 300 away from the front ring 200, after the front ring 200 calibrates the time to zero, the locking member 400 abuts against the bottom end of the stopper assembly 300, so that the top end of the stopper assembly 300 abuts against the positioning portion 201; in this way, the position of the front ring 200 can be fixed and will not rotate due to misoperation or contact. The accuracy of the timing of the front ring 200 can be ensured.

[0079] Optional, see Figure 3 As shown, Figure 3 The outer wall of the body 100 is provided with a receiving cavity 106, and the locking member 400 is movably installed in the receiving cavity 106; the bottom end of the stopper assembly 300 extends into the receiving cavity 106.

[0080] Specifically, in the embodiment of the present application, the accommodating cavity 106 can be integrally formed with the body 100. Specifically, it can be integrally formed with the middle frame 103. Optionally, the accommodating cavity 106 can also be formed on the middle frame 103 by secondary hole digging. This embodiment of the present application is not limited to this.

[0081] Optionally, the accommodating cavity 106 may be a groove formed along a side wall of one side of the middle frame 103 (eg Figure 3 As shown), the groove may be specifically located on the side wall away from the side where the time adjustment handle of the watch is provided.

[0082] In some possible embodiments, the accommodating cavity 106 may also be a notch formed directly below the stop assembly 300. For example, when the locking member 400 is a gear or a spring, the locking member 400 may be disposed in the notch.

[0083] For further information, please refer to Figure 3 As shown, the locking member 400 includes a first part 401 and a second part 402; the first end 4011 of the first part 401 is hinged to the body 100. Specifically, an axial hole is provided on the middle frame 103, and a shaft rod is provided at the first end 4011, and the shaft rod is inserted into the axial hole to achieve hinge connection; or, an axial hole is also provided at the first end 4011, and the shaft rod is inserted into two axial holes in sequence to achieve hinge connection.

[0084] In some possible embodiments, the shaft rod may be disposed on the middle frame 103 , and an shaft hole may be opened at the first end 4011 .

[0085] The second portion 402 is disposed on the first portion 401 , and the second portion 402 is located between the first portion 401 and the body 100 , and the second portion 402 abuts against the bottom end of the stop assembly 300 .

[0086] Specifically, refer to Figure 3 As shown, the second part 402 can be arranged on the side wall of the first part 401 close to the body 100. After the first part 401 is received in the accommodating cavity 106, the second part 402 is located below the stopper assembly 300, thereby abutting against the bottom end of the stopper assembly 300.

[0087] In a specific example, the second part 402 may be located directly below the stop assembly 300.

[0088] It can be understood that the second part 402 may also be located below the side of the stop assembly 300. For example, a horizontal stop wall is provided at the bottom end of the stop assembly 300, and the second part 402 may also abut against the horizontal stop wall.

[0089] Optionally, in the embodiments of the present application, the locking member 400 may be an integrally formed structure; or in some possible ways, the locking member 400 may be formed by turning on a lathe.

[0090] It is easy to understand that, in order to ensure the beauty of the appearance of the watch, in the embodiments of the present application, the shape of the first part 401 may be adapted to or match the shape of the side wall of the body 100. For example, it is in the Figure 3 arc structure shown.

[0091] It can be understood that when it is necessary to rotate the front ring 200 to zero the minute hand of the watch; it is necessary to let the second part 402 leave from the bottom end of the stop assembly 300, that is, no longer abut against the bottom end of the stop assembly 300. This requires pulling out the first part 401 from the accommodation cavity 106. In order to facilitate pulling out the first part 401 from the accommodation cavity 106, referring to Figure 1 and Figure 3 shown, in the embodiments of the present application, a third part 403 is further provided at the second end 4012 of the first part 401; the third part 403 protrudes from the accommodation cavity 106.

[0092] In this way, it is possible to conveniently pull out the first part 401 and the second part 402 from the accommodation cavity 106 through the third part 403, facilitating the re-rotation and adjustment of the front ring 200.

[0093] It can be understood that in some possible examples, it may also be that a dial (not shown in the figure) is provided at the hinge joint between the first end 4011 and the body 100, and the dial is toggled to drive the rotating shaft and the first part 401 to leave the accommodation cavity 106. In this case, the shaft rod may be fixedly connected to the first end 4011.

[0094] Furthermore, since the second part 402 needs to abut against the bottom end of the stop assembly 300, in order to facilitate the second part 402 to be easily and smoothly inserted into the bottom end of the stop assembly 300. Continuing to refer to Figure 3 shown, in the embodiments of the present application, a guiding surface 4021 is provided at the edge of the second part 402, and the guiding surface 4021 is used to smoothly transition the bottom end of the stop assembly 300 to the second part 402.

[0095] Specifically, in the embodiments of the present application, the guiding surface 4021 can be an inclined surface formed by chamfering; in some possible ways, the guiding surface 4021 can also be an arc surface formed by rounding.

[0096] It can be understood that in the embodiments of the present application, the bottom end of the stopper assembly 300 can be set in the form of a dome, a rounded chamfer or a chamfer. In this way, it can be further ensured that the second part 402 is smoothly inserted into the bottom end of the stopper assembly 300.

[0097] It should be noted that after the locking member 400 is received in the accommodation cavity 106, that is, after the second part 402 abuts against the bottom of the stopper assembly 300; this can limit the position of the front ring 200 and can prevent the front ring 200 from rotating due to accidental touch. However, it is also necessary to prevent the locking member 400 from popping out or falling out of the accommodation cavity 106 and failing to lock the front ring 200. To avoid this situation, in the embodiments of the present application, convex points (not shown in the figure) are provided on the upper and lower surfaces of the second end 4012. The convex points can be round dots protruding from the upper and lower surfaces of the second end 4012 and can be integrally formed with the second end 4012. In this way, after the locking member 400 is received in the accommodation cavity 106, the convex points of the second end 4012 will generate a large frictional force with the inner wall of the accommodation cavity 106, which can prevent the locking member 400 from coming out.

[0098] In some possible examples, it can also be that a silica gel layer is covered on the surface of the second end 4012, and the frictional force is generated between the silica gel layer and the inner wall of the accommodation cavity 106, which can also effectively prevent the locking member 400 from coming out.

[0099] In other possible examples, a magnetic member (such as an iron block or a magnet) can also be provided on the inner side wall of the accommodation cavity 106; and a magnetic member is also provided at the second end 4012, and the two magnetic members can be arranged with opposite poles. In this way, the attraction of the two magnets can be used to prevent the locking member 400 from coming out.

[0100] In a specific example, referring to Figure 4 shown, Figure 4 is Figure 2 a partial enlarged view of B in. In the embodiments of the present application, a first channel 107 is axially provided on the main body 100. The stopper assembly 300 includes a stopper 301 and a reset member 302; the first channel 107 is located on one side of the front ring 200. The stopper 301 is inserted into the first channel 107, and the reset member 302 is arranged in the first channel 107. One end of the reset member 302 is connected to the stopper 301, and the other end of the reset member 302 is connected to the inner wall of the first channel 107. The reset member 302 is used to push the stopper 301 so that the top end of the stopper 301 abuts against the positioning portion 201.

[0101] Optionally, in the embodiments of the present application, the first channel 107 may be a counterbore as shown in Figure 4 . The reset member 302 may be a spring, and one end of the spring connected to the first channel 107 abuts against the transition step of the counterbore.

[0102] In some other possible ways, the reset member 302 may also be two magnets. One magnet is disposed on the inner wall of the first channel 107, and the other magnet is disposed on the stopper 301. The attraction or repulsion of the magnets can be used to reset the stopper 301.

[0103] Further, referring to Figure 5 and Figure 6 shown, Figure 5 is a schematic structural view of the front ring of the front ring locking watch case provided by the embodiments of the present application, Figure 6 is a schematic structural view of a stopper of the front ring locking watch case provided by the embodiments of the present application.

The first stopper section 3011 abuts against the positioning portion 201, the positioning section 3012 is connected to the reset member 302, and the second stopper section 3013 abuts against the locking member 400.

[0104] Optionally, the positioning portion 201 includes ratchet teeth, and the end of the first stopper section 3011 is an inclined surface, and the inclination direction of the inclined surface is the same as the inclination direction of the ratchet teeth.

[0105] It can be understood that the positioning portion 201 may also be the groove formed by recessing from the bottom surface of the front ring 200 as described above. The groove may be a circular groove, a polygonal groove, or an elliptical groove. The end of the first stopper section 3011 may be a round top surface or an arc surface. In this way, the front ring 200 can achieve bidirectional rotation.

[0106] Optionally, referring to Figure 7 shown, Figure 7 is another schematic structural view of the stopper of the front ring locking watch case provided by the embodiments of the present application. In the embodiments of the present application, a positioning groove 3013a is recessed on the peripheral wall of the second stopper section 3013, and the locking member 400 is inserted into the positioning groove 3013a.
