Description

Technical Field

[0001] The utility model relates to the technical field of watch parts, in particular to a watch structure with a stop-second device. Background Art

[0002] The biggest difference between a mechanical watch with stop-seconds and without stop-seconds lies in the movement state of the second hand. In the stop-seconds mode, the second hand will stop moving, which can make time adjustment more accurate; while in the non-stop-seconds mode, the second hand will keep moving, which can make time adjustment more convenient.

[0003] In the prior art, for example, the watch structure with a stop-second device in Chinese Patent CN203732887U includes a balance wheel, a clutch wheel, a vertical wheel, a stem and a stop-second lever installed on the main plate. One end of the stem is connected to the vertical wheel, and the vertical wheel meshes with the clutch wheel; the stop-second lever includes a driving arm and a braking arm. The driving arm is embedded in the clutch wheel groove, and the braking arm is located on one side of the balance wheel. Its beneficial effect is that, due to the components with the stop-second function, stop-seconds can be quickly performed, and its manufacturing process is simple. After stamping, blanking and bending, heat treatment and electroplating can complete the processing of parts.

[0004] In the above patent, by pulling the stem, the clutch wheel is separated from the vertical wheel. At this time, since the driving arm is in the middle of the groove of the clutch wheel, the driving arm drives the braking arm to rotate a certain angle under the action of the leftward movement force of the clutch wheel, so that the braking arm contacts the balance wheel, and the balance wheel in rapid movement stops instantly, realizing the stop-second function. However, the stem of the stop-second function is prone to rotate under the action of external friction or be accidentally touched by personnel, resulting in the second hand being in the braking state for a long time, causing damage to the movement or components. Therefore, a new watch structure with a stop-second device needs to be proposed. Summary of the Utility Model

[0005] The utility model mainly provides a watch structure with a stop-second device that can prevent the stem from rotating under the action of external friction, causing the second hand to be braked for a long time and damaging the movement or components.

[0006] To achieve the above object, the utility model adopts the following technical scheme: A watch structure with a stop-second device, including: a watch body, and a limiting component fixedly connected to the outer surface of the watch body; the limiting component, which includes a protective shell fixedly connected to the outer surface of the watch body, symmetrically fixed sliding rods on the inner surface of the protective shell, a limiting block is arranged between the outer surfaces of the two sliding rods, and the top of the limiting block is symmetrically fixedly connected with first springs, and both of the two first springs are fixedly connected to the inner top of the protective shell.

[0007] Preferably, a stem is provided on the outer surface of the watch body, and the outer surface of the stem fits with the outer surface of the limit block. By providing the limit block on the outer surface of the stem, when the limit block fits with the outer surface of the stem, it plays a braking role to prevent the stem from rotating under the action of external force and driving the second hand to stop or move.

[0008] Preferably, a plurality of raised blocks are equidistantly arranged on the outer surface of the stem, and a plurality of grooves are equidistantly formed on the outer surface of the limit block, which is convenient for increasing the friction between the stem and the limit block and preventing the stem from rotating under the action of external force.

[0010] Preferably, a second spring is fixedly connected between the fixed plate and the movable plate, and a contact block is fixedly connected to the outer surface of one side of the movable plate, which is convenient for using the resilience of the second spring to stretch between the fixed plate and the movable plate, so that the contact block always fits with the inner surface of the protective case.

[0011] Preferably, a fixing hole is formed on the inner surface of one side of the protective case, a pressing groove is formed on the outer surface of one side of the protective case, and the pressing groove is communicated with the fixing hole, which is convenient for a person's finger to press the pressing groove to force the contact block in the fixing hole to contract and move inward.

[0012] Preferably, the outer surface of the contact block fits with the inner surface of the protective case, and the position of the contact block is matched with that of the fixing hole, which is convenient for the contact block to be pushed into the fixing hole corresponding to the position under the action of the spring when the limit block moves up and touches the top, playing a limiting role to prevent the limit block from falling and affecting the person from rotating the stem.

[0013] Preferably, sliding tubes are symmetrically and fixedly connected to the inner surface of the limit block, and the outer surfaces of two sliding rods are respectively slidably connected to the inner surfaces of the two sliding tubes, which is convenient for the limit block to move up and down, and to slide on the outer surface of the sliding rod through the sliding tube, so that it can move smoothly.

[0014] Compared with the prior art, the advantages and positive effects of the present utility model are as follows

[0015] 1. In the utility model, when in use, through the cooperation of the watch body and the limit assembly, the limit block is pushed upward to separate it from the stem, and then the second spring pushes the movable plate to move outward, so that the contact block slides and inserts into the fixed hole for limiting, which is convenient for personnel to stop the seconds on the stem, and by pressing the pressing groove with fingers, the contact block is forced to separate from the fixed hole, and under the action of the rebound force of the two first springs, the arc surface of the limit block is pushed to contact the outer surface of the stem, which plays a limiting role and prevents the stem from rotating. This solves the problem in the background technology that the stem rotates due to accidental touch or external friction, causing the second hand to be braked for a long time without the personnel noticing, causing damage to the movement or parts.

[0023] To more clearly understand the above-mentioned objects, features, and advantages of the present utility model, the present utility model will be further described below in conjunction with the accompanying drawings and embodiments. It should be noted that, without conflict, the embodiments of the present application and the features in the embodiments may be combined with each other.

[0024] Please refer to Figures 1-5 , the present utility model provides a technical solution: a watch structure of a stop-second device, including: a watch body 1, and a limiting component 2 fixedly connected to the outer surface of the watch body 1; the limiting component 2, the limiting component 2 includes a protective case 201 fixedly connected to the outer surface of the watch body 1, sliding rods 202 symmetrically and fixedly connected to the inner surface of the protective case 201, a limiting block 203 is arranged between the outer surfaces of the two sliding rods 202, first springs 204 are symmetrically and fixedly connected to the top of the limiting block 203, and both of the two first springs 204 are fixedly connected to the inner top of the protective case 201.

[0025] As Figures 1-2 shown, a stem 3 is arranged on the outer surface of the watch body 1, and the outer surface of the stem 3 is in contact with the outer surface of the limiting block 203. By arranging the limiting block 203 on the outer surface of the stem 3, when the outer surface of the limiting block 203 is in contact with the outer surface of the stem 3, a braking effect is achieved, preventing the stem 3 from rotating under the action of an external force and driving the second hand to stop or move.

[0026] As Figures 2-3 and Figure 5 shown, a plurality of raised blocks 4 are arranged at equal intervals on the outer surface of the stem 3, and a plurality of grooves 206 are arranged at equal intervals on the outer surface of the limiting block 203, which is convenient for increasing the friction force between the stem 3 and the limiting block 203 and preventing the stem 3 from rotating under the action of an external force.

[0027] As Figure 5 shown, an installation groove 207 is formed on one side outer surface of the limiting block 203, a fixing plate 208 is fixedly connected to the inner surface of the installation groove 207, and a movable plate 209 is slidably connected to the inner surface of the installation groove 207, which is convenient for fixing the fixing plate 208 in the installation groove 207 and making the fixing plate 208 and the movable plate 209 contract into the installation groove 207.

[0028] As Figure 5 shown, a second spring 210 is fixedly connected between the fixing plate 208 and the movable plate 209, and a contact block 211 is fixedly connected to one side outer surface of the movable plate 209, which is convenient for using the resilience of the second spring 210 to stretch between the fixing plate 208 and the movable plate 209, so that the contact block 211 always fits on the inner surface of the protective case 201.

[0029] As Figure 4As shown, a fixing hole 212 is provided on one side of the inner surface of the protective case 201, and a pressing groove 213 is provided on the outer surface of one side of the protective case 201. The pressing groove 213 is communicated with the fixing hole 212, which facilitates the user's finger to press the pressing groove 213, forcing the contact block 211 in the fixing hole 212 to contract and move inward.

[0030] As Figures 3-5 shown, the outer surface of the contact block 211 fits the inner surface of the protective case 201, and the position of the contact block 211 matches that of the fixing hole 212. When the limiting block 203 moves upward and touches the top, the contact block 211 is pushed into the corresponding fixing hole 212 under the action of the spring, playing a limiting role to prevent the limiting block 203 from falling and affecting the user's rotation of the handle shaft 3.

[0031] As Figure 3 shown, sliding tubes 205 are symmetrically and fixedly connected to the inner surface of the limiting block 203, and the outer surfaces of two sliding rods 202 are respectively slidably connected to the inner surfaces of the two sliding tubes 205, which facilitates the smooth movement of the limiting block 203 when it moves up and down by sliding the sliding tubes 205 on the outer surfaces of the sliding rods 202.

[0032] The usage method and working principle of this device: When the watch stops the second hand, push the limiting block 203 upward, so that it moves upward along the outer surfaces of the two sliding rods 202 through the two sliding tubes 205. The limiting block 203 will squeeze the two first springs 204 during movement, causing them to deform and contract. At the same time, the fixing plate 208 fixed in the installation groove 207, and the second spring 210 fixed between it and the movable plate 209 will, under the action of elastic reset, make the contact block 211 fixedly arranged on the surface of the movable plate 209 always fit and slide upward on the inner surface of the protective case 201. When the limiting block 203 touches the top, the contact block 211 will slide and insert into the corresponding fixing hole 212 under the restoring force of the second spring 210, so that the limiting block 203 stays at the inner top position of the protective case 201, facilitating the user to rotate the handle shaft 3 to adjust the position where the second hand stays in the dial of the watch body 1 for precise time alignment. After the adjustment is completed, the user presses with a finger in the pressing groove 213, forcing the contact block 211 to contract towards the inside of the protective case 201, separating it from the fixing hole 212. At this time, under the restoring force of the two first springs 204, the limiting block 203 is pushed to move downward along the outer surfaces of the two sliding rods 202 until it touches the outer surface of the handle shaft 3. A plurality of grooves 206 are equidistantly arranged on the arc-shaped outer surface of the limiting block 203, and a plurality of raised blocks 4 are equidistantly arranged on the outer surface of the handle shaft 3, which increases the frictional force between the limiting block 203 and the handle shaft 3, limits the handle shaft 3, prevents it from rotating under the action of external force, and causes the handle shaft 3 to drive the second hand to be braked for a long time, damaging the movement or components, and improving the service life of the watch.

[0033] The above are only the preferred embodiments of the present utility model, and are not intended to limit the present utility model in other forms. Any person skilled in the art may use the technical content disclosed above to make changes or modifications into equivalent embodiments with equivalent changes and apply them to other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of the present utility model without departing from the content of the technical solution of the present utility model still fall within the protection scope of the technical solution of the present utility model.
