Description

Technical Field

[0001] The present invention relates to the technical field of watches, and in particular to a magnetic watch clasp and a watch. Background Art

[0002] At present, there are many watches on the market that use magnetic clasps, but most of them have unstable connection methods or complex structures. Usually, it is easy for people to operate them inconveniently and the clasps are difficult to lock when they are worn.

[0003] On the one hand, it leads to high production costs, inconvenience in use, and is not conducive to people's daily use; on the other hand, some magnetic clasps with simple structures are easy to fall off during daily use due to the lack of a fixed structure, which may cause economic losses.

[0004] Therefore, whether it is possible to design a new type of magnetic clasp and watch that can simplify the structure of the magnetic clasp as much as possible while being easy to operate is the problem that this patent wants to solve. Summary of the invention

[0005] In view of the above defects in the prior art, the present invention provides a magnetic watch clasp and a watch, which effectively utilizes the attraction of the magnet and the shape structure of the clasp to simplify the structure of the magnetic watch clasp and facilitate operation.

[0006] The technical solution provided by the present invention is as follows:

[0007] A magnetic watch buckle, used to connect a first watch strap and a second watch strap, comprising a watch buckle seat and a watch buckle cover that cooperate with each other, wherein the watch buckle seat and the watch buckle cover are respectively mounted on the first watch strap and the second watch strap;

[0008] A button is arranged on the surface of the buckle seat facing the buckle cover, and a spring is accommodated between the button and the buckle seat; a button through hole matching the button position is arranged on the surface of the buckle cover facing the buckle seat; at least one of the buckle seat and the buckle cover is equipped with a magnet to generate magnetic attraction;

[0009] In the first state, the button and the button through hole are staggered in position, the buckle cover compresses the spring under the action of the magnetic force, and the buckle cover fits the buckle seat; in the second state, the button and the button through hole correspond in position, and the button is inserted into the button through hole; external force acts on the buckle seat or the buckle cover to complete the switching from the first state to the second state.

[0010] On the one hand, the present invention is connected to the first and second straps respectively through the buckle seat and the buckle cover. On the other hand, the buckle cover is first pressed against the button by magnetic attraction, and then the buckle is locked by the cooperation between the limit mechanism and the button on the buckle seat and the buckle cover. The most creative part of the present invention is that: first, the button installed on the buckle seat is automatically pressed by the magnetic attraction of the magnet, so when the user wears it, there is no need to press the buckle cover to press the button, which greatly facilitates the user's operation; secondly, the design of the snap-fit ​​method is ingenious, first the button is inserted into the button through hole to limit the relative movement of the buckle cover in the length and width direction of the strap; then the limit mechanism cooperates with each other to limit the relative movement of the buckle cover in the thickness direction of the strap. The snap-fit ​​method is ingeniously designed, simple in structure and low in manufacturing cost.

[0011] Furthermore, the buckle seat and the buckle cover are correspondingly provided with limiting mechanisms, and in the second state, the buckle seat and the buckle cover are positioned by the limiting mechanisms.

[0012] Specifically, the buckle seat includes:

[0013] The buckle seat body is an L-shaped structure, the L-shaped structure includes a first plate portion and a second plate portion at a certain angle, the first plate portion extends along the length direction of the strap, the second plate portion extends along the cross-sectional direction of the strap, and the second plate portion is hinged to the first strap;

[0014] A first limiting mechanism is provided on a surface of the first plate portion away from the first strap;

[0015] A second limiting mechanism is provided on a surface of the second plate portion away from the first strap;

[0016] The clasp cover comprises:

[0017] The buckle cover body is an L-shaped structure, the L-shaped structure includes a third plate portion and a fourth plate portion at a certain angle, the third plate portion extends along the length direction of the strap, the fourth plate portion extends along the cross-sectional direction of the strap, and the second plate portion is hinged to the second strap;

[0018] A third limiting mechanism is arranged on a surface of the third plate portion away from the second strap;

[0019] a fourth limiting mechanism, arranged on a surface of the fourth plate portion away from the second strap;

[0020] The magnet further includes a buckle base magnet and a buckle cover magnet. The buckle base magnet is embedded in the surface of the first plate portion facing the buckle cover, and the buckle cover magnet is embedded in the surface of the third plate portion facing the buckle base, and the position corresponds to the buckle base magnet.

[0021] This patent provides the specific structure of the buckle seat and the buckle cover and the connection position with the first strap and the second strap. The first limiting mechanism cooperates with the fourth limiting mechanism, and the second limiting mechanism cooperates with the third limiting mechanism to achieve the function of positioning the buckle seat and the buckle cover. In addition, it provides the embedding position of the magnet to facilitate practical application.

[0022] Further, the first limiting mechanism is a boss formed on the surface of the first plate portion away from the first strap along the length direction of the strap, and the size of the boss along the length direction of the strap is not greater than the size of the fourth plate portion along the length direction of the strap; the second limiting mechanism is a groove formed on the surface of the second plate portion away from the first strap along the length direction of the strap, and its shape corresponds to the button; the third limiting mechanism is a boss formed on the surface of the third plate portion away from the second strap, and its shape matches the groove of the second limiting mechanism; the fourth limiting mechanism is a groove formed on the surface of the fourth plate portion away from the second strap, and its shape matches the boss of the first limiting mechanism.

[0023] This patent provides a specific limiting mechanism, which is essentially realized by the cooperation between the convex and concave, and the relative movement of the buckle cover in the thickness direction of the strap is limited by the mutual cooperation between the convex platform and the concave platform. This limiting mechanism is not only very simple in structure and effectively reduces the size of the buckle, but also has high reliability, firmness and durability.

[0024] Specifically, the clasp base magnet includes a first magnet and a second magnet, which are respectively located on both sides of the button; the clasp cover magnet includes a third magnet and a fourth magnet, which correspond to the positions of the first magnet and the second magnet, respectively.

[0025] In this patent, corresponding magnets are installed on the buckle seat and the buckle cover respectively. Therefore, when the buckle seat and the buckle cover are close to each other, the button is automatically pressed under the attraction of the magnets. The buckle can be locked by simply pushing the buckle cover into the buckle seat along the strap, which is very convenient to use.

[0026] Furthermore, the first plate portion is provided with a button fixing through hole, in which a spring support seat is fixed; the spring is mounted on the spring support seat and connected to the button, and the button can slide relatively in the button fixing through hole.

[0027] This patent further designs the shape and installation structure of the key, the key position corresponds to the key through hole, is installed in the key fixing through hole, and is supported and fixed by the spring and the spring support seat. This installation structure is simple, practical, and convenient for the maintenance and replacement of the key spring.

[0028] Further preferably, the first plate portion, the second plate portion, the first limiting mechanism and the second limiting mechanism are an integrated structure; the second plate portion, the fourth plate portion, the third limiting mechanism and the fourth limiting mechanism are an integrated design.

[0029] In this patent, the integrated design of the buckle cover and the integrated design of the buckle seat can improve the reliability of the buckle and make it sturdy and durable.

[0030] Further preferably, the buckle cover, the buckle seat and the button are all metal parts or plastic parts. Different parts can be selected according to different users and usage scenarios.

[0031] This patent also discloses a watch, comprising the novel magnetic watch clasp. The novel magnetic watch clasp is hinged on the watch strap.

[0032] The technical effects of the present invention are:

[0033] 1. The button installed on the buckle seat is automatically pressed by the attraction of the magnet. When the user wears it, there is no need to press the buckle cover to press the button, which greatly facilitates the user's operation;

[0034] 2. The design of the snap-fitting method is ingenious. First, the button is inserted into the button through hole to limit the relative movement of the buckle cover in the length and width directions of the strap; then the third limiting mechanism cooperates with the second limiting mechanism, and the fourth limiting mechanism cooperates with the first limiting mechanism to limit the relative movement of the buckle cover in the thickness direction of the strap. The snap-fitting method is ingeniously designed, simple in structure and low in manufacturing cost.

[0035] 3. The limit mechanism uses convex and concave matching, and the relative movement of the buckle cover in the thickness direction of the strap is achieved through the mutual cooperation between the boss and the groove. This limit mechanism is not only very simple in structure and effectively reduces the size of the buckle, but also has high reliability, firmness and durability.

[0036] 4. The button position corresponds to the button through hole, and is installed in the button fixing through hole, supported and fixed by the spring and the spring support seat. This installation structure is simple, practical, and convenient for the maintenance and replacement of the button spring.

[0037] 5. The integrated design of the buckle cover and the buckle seat improves the reliability of the buckle and makes it sturdy and durable. BRIEF DESCRIPTION OF THE DRAWINGS

[0052] In addition, in the description of the present application, the terms "first", "second", etc. are only used to distinguish the description and cannot be understood as indicating or implying relative importance.

[0053] In order to more clearly illustrate the embodiments of the present invention or the technical solutions in the prior art, the specific implementation methods of the present invention will be described below with reference to the accompanying drawings. Obviously, the accompanying drawings described below are only some embodiments of the present invention. For ordinary technicians in this field, other drawings and other implementation methods can be obtained based on these drawings without creative work.

[0054] As a specific example, Figure 1 As shown, a new type of magnetic watch buckle is provided, wherein the first watch strap 40 and the second watch strap 10 are connected respectively through the watch buckle seat 30 and the watch buckle cover 20, a button 34 is provided on the surface of the watch buckle seat 30 facing the watch buckle cover 20, and a spring 35 is accommodated between the button 34 and the watch buckle seat 30; a button through hole 22 matching the position of the button 34 is provided on the surface of the watch buckle cover 20 facing the watch buckle seat 30; at least one of the watch buckle seat 30 and the watch buckle cover 20 is equipped with a magnet to generate magnetic attraction. If only one magnet is provided on the watch buckle seat 30, the watch buckle cover 20 is magnetic, and vice versa; if multiple magnets are provided, they can be respectively provided at the corresponding positions of the watch buckle seat 30 and the watch buckle cover 20.

[0055] In the first state, the button 34 and the button through hole 22 are staggered in position, and the buckle cover 20 compresses the spring 35 under the action of the magnetic force, so that the buckle cover 20 and the buckle seat 30 fit together; in the second state, the button 34 and the button through hole 22 correspond in position, and the button 34 is inserted into the button through hole 22; external force is applied to the buckle seat 30 or the buckle cover 20 to complete the switching from the first state to the second state.

[0056] Furthermore, limiting mechanisms are correspondingly provided on the buckle seat 30 and the buckle cover 20. In the second state, the buckle seat 30 and the buckle cover 20 are positioned by the limiting mechanisms.

[0057] Specifically, Figure 1As shown, the buckle seat 30 includes: an L-shaped buckle seat body, including a first plate portion extending along the length direction of the strap at a certain angle and a second plate portion extending along the cross-sectional direction of the strap, and the second plate portion is hinged to the first strap 40; a first limiting mechanism 31 is arranged on the surface of the first plate portion away from the first strap 40; a second limiting mechanism 33 is arranged on the surface of the second plate portion away from the first strap 40; a button 34 and a buckle seat magnet 36 are arranged on the surface of the first plate portion facing the buckle cover 20.

[0058] The buckle cover 20 includes: an L-shaped buckle cover body, including a third plate portion extending along the length direction of the strap at a certain angle and a fourth plate portion extending along the cross-sectional direction of the strap, and the fourth plate portion is hinged to the second strap 10; a third limiting mechanism 23 is provided on the surface of the third plate portion away from the second strap 10; a fourth limiting mechanism 24 is provided on the surface of the fourth plate portion away from the second strap 10; Figure 2 As shown, a button through hole 22 and a buckle cover magnet 21 are provided on the surface of the third plate portion facing the buckle seat 30 , and the position of the buckle cover magnet 21 corresponds to the buckle seat magnet 36 .

[0059] Specifically, there are three states during use, among which,

[0060] In the first state, Figure 3 As shown, the clasp cover 20 is close to the clasp seat 30. At this time, the spring 35 is compressed under the attraction between the clasp cover magnet 21 and the clasp seat magnet 36, so that the clasp cover 20 presses the button 34, and the clasp cover 20 fits with the clasp seat 30.

[0061] The most significant feature of this state is that the spring 35 can be compressed under the attraction between the clasp cover magnet 21 and the clasp seat magnet 36, and the clasp cover 20 and the clasp seat 30 can be fitted together. On the contrary, if the attraction between the clasp cover magnet 21 and the clasp seat magnet 36 cannot compress the spring 35, the clasp cover 20 and the clasp seat 30 cannot be fully fitted together, and only artificial pressure can be applied to make the clasp cover 20 and the clasp seat 30 fully fit together.

[0062] In the second state, if Figure 4 As shown, the buckle cover 20 is pushed into the buckle seat 30 along the length direction of the strap. At this time, the button 34 rebounds and is inserted into the button through hole 22, limiting the relative movement of the buckle cover 20 in the length direction of the strap; the third limiting mechanism 23 cooperates with the second limiting mechanism 33, and the fourth limiting mechanism 24 cooperates with the first limiting mechanism 31, limiting the relative movement of the buckle cover 20 in the thickness direction and width direction of the strap.

[0063] The premise for achieving this state is that the buckle cover 20 and the buckle seat 30 are completely fitted together in the illustrated state 1, otherwise, when the buckle cover 20 is pushed into the buckle seat 30 along the length direction of the strap, the third limiting mechanism 23 and the second limiting mechanism 33 cannot cooperate, and the fourth limiting mechanism 24 and the first limiting mechanism 31 cannot cooperate;

[0064] In the third state, the button 34 is manually pressed and the buckle cover 20 and the buckle seat 30 are pulled open. At this time, the button 34 exits the button through hole 22, the third limiting mechanism 23 disengages from the second limiting mechanism 33, and the fourth limiting mechanism 24 disengages from the first limiting mechanism 31, that is, the buckle cover 20 disengages from the buckle seat 30 along the length direction of the strap.

[0065] Specifically, the first limiting mechanism 31 is a boss formed on the surface of the first plate portion away from the first strap 40 along the length direction of the strap, and is designed as a square structure in the drawings of this patent specification, but other shapes can be used in specific implementations, such as other polygonal or circular shapes. And the size of the boss along the length direction of the strap is not greater than the size of the fourth plate portion along the length direction of the strap;

[0066] The second limiting mechanism 33 is a groove formed on the surface of the second plate portion away from the first strap 40 along the length direction of the strap, and is designed as a rectangular parallelepiped structure in the drawings of this patent, and can also be designed as a boss of other shapes;

[0067] The third limiting mechanism 23 is a boss formed on the surface of the third plate portion away from the second strap 10, and its shape matches the groove of the second limiting mechanism 33;

[0068] The fourth limiting mechanism 24 is a groove formed on the surface of the fourth plate portion away from the second strap 10 , and its shape matches the boss of the first limiting mechanism 31 .

[0069] In another specific embodiment, the first limiting mechanism 31 is a groove on the surface of the first plate portion away from the first strap 40 along the length direction of the strap; the second limiting mechanism 33 is a boss formed on the surface of the second plate portion away from the first strap 40 along the length direction of the strap; the third limiting mechanism 23 is a groove formed on the surface of the third plate portion away from the second strap 10, and its shape matches the boss of the second limiting mechanism 33; the fourth limiting mechanism 24 is a boss formed on the surface of the fourth plate portion away from the second strap 10, and its shape matches the groove of the first limiting mechanism 31.

[0070] like Figure 5 As shown, the first plate portion is provided with a button fixing through hole, in which a spring support seat 32 is fixed; a spring 35 is mounted on the spring support seat 32 and connected to a button 34, and the button 34 can slide relatively in the button fixing through hole.

[0071] In another specific embodiment, Figure 6 As shown, the button 34 is a concave structure with a flange, which is arranged in the button fixing through hole. The flange structure of the button 34 is essentially matched with the step inside the button fixing through hole, which is used to clamp the button 34 in the button fixing through hole to prevent the button 34 from popping out of the button fixing through hole along the thickness direction of the watchband. The concave structure of the button 34 is used to fix one end of the spring 35 to prevent the spring 35 from being unevenly stressed on the button 34 during use, causing the button 34 to be stuck in the button fixing through hole after being pressed into the button fixing through hole.

[0072] Furthermore, if Figure 7 As shown, a spring support seat 32 having a shape matching that of the key through hole 22 is fixed to the end of the key fixing through hole away from the key 34, for fixing a support spring 35. Specifically, the spring support seat 32 and the key fixing through hole are threaded or interference fit. A groove can also be provided at the end of the spring support seat 32 facing the key 34 for fixing one end of the spring 35. In addition, one end of the spring 35 can also be directly welded or embedded on the end of the spring support seat 32 facing the key 34, but this solution is not conducive to replacing the spring 35.

[0073] As a specific embodiment, a total of four magnets are provided in this patent. In this patent, the first magnet and the second magnet are respectively provided on both sides of the button 34 on the buckle seat 30; and the third magnet and the fourth magnet are provided at the corresponding position of the buckle cover 20.

[0074] In this patent, the first magnet and the second magnet are respectively arranged on both sides of the button 34 on the buckle seat 30, and the third magnet and the fourth magnet are arranged at corresponding positions of the buckle cover 20. This arrangement of magnets is only a specific embodiment of this patent.

[0075] Further preferably, only a first magnet and a clasp cover 20 located next to the button 34 on the clasp base 30, and a third magnet corresponding to the first magnet may be provided, and the attraction between the first magnet and the third magnet can compress the spring 35 to make the clasp cover 20 fit with the clasp base 30; for another example, a plurality of buttons may be provided on the clasp base 30, each button is provided with a spring 35 corresponding to the button, and a plurality of magnets are respectively provided on the clasp base 30 and the clasp cover 20, and the attraction between the magnets can compress the spring 35 to make the clasp cover 20 fit with the clasp base 30.

[0076] This patent adopts the integrated structure of the buckle seat 30 and the integrated structure of the buckle cover 20, specifically, the first plate portion, the second plate portion, the first limiting mechanism 31 and the second limiting mechanism 33 are integrated structures; the second plate portion, the fourth plate portion, the third limiting mechanism 23 and the fourth limiting mechanism 24 are integrated structures. In practical applications, a multi-component assembly method can also be used.

[0077] The buckle cover 20, the buckle seat 30 and the button 34 are all metal parts or plastic parts. If metal parts are used, the reliability of this new type of magnetic clasp can be enhanced, and the use of metal parts has a certain texture and a better wearing experience, but metal parts have a large mass and are not convenient for children to wear. However, in actual production, metal parts require higher production costs, and the manufacturing process is more complicated than plastic parts, which is suitable for use in the field of adult watches; on the other hand, the use of plastic parts is simple to make, and other molding processes including injection molding can be used, which is convenient for integrated design and can reduce production costs. In terms of wearing experience, the use of plastic parts has a lighter mass, which is more conducive to the promotion and use in the field of children's watches.

[0078] The embodiment of the present invention further provides a watch, such as Figures 1 to 5 As shown, the novel magnetic watch clasp in the above embodiment is hinged on the watch strap, specifically, the first watch strap 40 and the second watch strap 10 of the watch are hinged respectively through the watch clasp seat 30 and the watch clasp cover 20. The hinged connection can be made by opening a through hole and using an axis connection, or by opening a blind hole and using a spring ear connection.

[0079] Specifically, on this type of watch, the connection method between the magnetic clasp and the strap can also be selected according to different usage scenarios. There are currently three common connection structures:

[0080] Through holes are respectively provided at one end of the buckle cover 20 and the buckle seat 30 for connecting the first strap 40 and the second strap 10, and through holes are also provided at corresponding positions of the straps, and then hinged through a rotating shaft. This connection structure is simple to manufacture and has low production cost. It is suitable for children or students, but the user experience is relatively poor.

[0081] Through holes are respectively provided at one end of the buckle cover 20 and the buckle seat 30 connecting the first strap 40 and the second strap 10, and blind holes are also provided at corresponding positions of the straps, and then hinged through the spring ears. This hinge structure is relatively complex to manufacture and has a high cost, but the blind hole design is conducive to the neatness of the product appearance and is suitable for users who have high requirements for appearance.

[0082] By connecting one end of the first strap 40 to the buckle cover 20, setting an axis with two ends fixed to the buckle cover 20 and a gap in the middle; the buckle seat 30 connects one end of the second strap 10, setting an axis with two ends fixed to the buckle seat 30 and a gap in the middle. Then pass one end of the first strap 40 through the gap between the buckle cover 20 and the axis; pass one end of the second strap 10 through the gap between the buckle seat 30 and the axis. And fix one end of the first strap 40 passing through the gap on the surface of the first strap 40; fix one end of the second strap 10 passing through the gap on the surface of the second strap 10. At this time, the through hole formed by the first strap 40 is fixed on the axis of the buckle cover 20, and the through hole formed by the second strap 10 is fixed on the axis of the buckle seat 30, so as to realize the connection between the magnetic buckle and the strap. This connection structure is mostly used in scenarios where the strap is thin and the material is soft, such as a cloth strap. This connection method is simple to make, low in production cost, and high in reliability, but the replacement of the strap is more complicated.

[0083] In addition, for different usage scenarios, other hinge structures in the prior art can also be used for connection. If there is no hinge requirement between the strap and the magnetic clasp, the strap can also be directly fixed to one end of the clasp cover 20 or the clasp seat 30. Therefore, this patent has a very wide range of applications.

[0084] When the magnetic clasp is worn, first, the clasp cover 20 is close to the clasp seat 30. At this time, the spring 35 is compressed under the magnetic attraction between the clasp cover magnet 21 and the clasp seat magnet 36, so that the clasp cover 20 presses the button 34, and the clasp cover 20 fits the clasp seat 30.

[0085] Secondly, the buckle cover 20 is pushed into the buckle seat 30 along the length direction of the strap. At this time, the button 34 rebounds and inserts into the button through hole 22, limiting the relative movement of the buckle cover 20 in the length direction of the strap; the third limiting mechanism 23 cooperates with the second limiting mechanism 33, and the fourth limiting mechanism 24 cooperates with the first limiting mechanism 31, limiting the relative movement of the buckle cover 20 in the thickness direction and width direction of the strap;

[0086] Finally, when disconnecting this new type of magnetic clasp, manually press the button 34 and pull open the clasp cover 20 and the clasp seat 30 along the length direction of the strap. At this time, the button 34 exits the button through hole 22, the third limiting mechanism 23 disengages from the second limiting mechanism 33, and the fourth limiting mechanism 24 disengages from the first limiting mechanism 31, that is, the clasp cover 20 disengages from the clasp seat 30 along the length direction of the strap.

[0087] The above is only a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the principle of the present invention. These improvements and modifications should also be regarded as the scope of protection of the present invention.
