Description

Technical Field

[0001] The invention relates to the technical field of watches, and in particular to a plastic bottom cover of a watch with transverse waterproofing. Background Art

[0002] The watch case is generally composed of three parts: the bottom cover, the top cover, and the annular shell that fits between the bottom cover and the top cover. The movement, hands and dial are set in the shell. The top cover and the annular shell are tightly fixed, and the movement, hands and dial are installed from the bottom cover and fixed in the shell, and finally the bottom cover is installed and sealed. This kind of watch has independent designs between the top cover, bottom cover and annular shell. During assembly, it is necessary to ensure the sealing and waterproof performance between the top cover and the annular shell, and between the bottom cover and the annular shell at the same time. The requirements are high. As long as one of them is not completely sealed, air, dust or water may enter, affecting the performance and life of the watch.

[0003] Prior art, such as Chinese patent "CN218512805U", provides a waterproof structure of a watch, which relates to the technical field of watches. Its technical solution includes an upper cover, a lower cover and a watch case. A placement groove is provided on the upper surface of the watch case, a button battery is installed at the bottom of the placement groove, a first installation groove is formed between the placement groove and the button battery, a connecting block is provided on the outside of the button battery, a first waterproof sealing ring is fixedly connected to the top of the connecting block, a second waterproof sealing ring is provided inside the placement groove, a first installation convex ring is provided on the lower surface of the upper cover, a first groove is provided on the outside of the button battery near the first waterproof sealing ring, and a second groove is provided on the placement groove near the second waterproof sealing ring; when the upper cover is installed in the watch case, a gap appears at the connection between the watch case and the upper cover, and an edge sealing ring is provided at the edge of the watch case to prevent moisture from entering the watch through the gap connection.

[0004] This solution adopts a method of tightly fitting a rubber ring and a convex ring at the joint of the watch case and the case cover to seal the joint of the watch case and the case cover, so that the watch has waterproof performance. However, since the watch needs to replace the battery or overhaul it regularly, the case cover needs to be disassembled frequently, which can easily cause the rubber ring to wear and damage, affecting the sealing function. Summary of the invention

[0005] The purpose of the present invention is to provide a plastic bottom cover of a watch with horizontal waterproofness in order to solve the above problems, in order to overcome the defects of the prior art that the case cover needs to be frequently disassembled, which easily causes the rubber ring to wear and damage and affects the sealing function, as described below for details.

[0006] To achieve the above object, the present invention provides the following technical solutions: The present invention provides a horizontally waterproof plastic bottom cover for a watch, comprising a watch case, the watch case is provided with a mounting groove, an organic core shell is arranged inside the mounting groove, and a watch cover is connected to the bottom of the mounting groove; A sealing mechanism is provided at the connection between the installation groove and the table cover, for sealing the connection between the installation groove and the table cover; A limiting mechanism is provided inside the installation groove for fixing the watch cover; A supporting mechanism is provided at the bottom of the watch cover for fixing the movement housing; The sealing mechanism includes an annular airbag, which is fixedly connected to the bottom of the watch case at the edge of the mounting groove. The top of the inner wall of the mounting groove is fixedly connected with an air ring. The inner wall of the watch case is provided with multiple air passages for connecting the air ring and the annular airbag. By arranging the annular airbag at the bottom of the watch case at the edge of the mounting groove, when the watch cover is closed, the squeezed annular airbag will fill the gap between the watch cover and the watch case to ensure the sealing between the watch cover and the watch case, so as to ensure its waterproof performance.

[0007] Preferably, the inner wall of the air ring is slidably connected with a slip ring, and a plurality of first springs are fixed to the inner wall of the air ring and the slip ring. Since the annular airbag is connected to the air ring through an airway, when the cover is opened, the tension of the first spring pushes the slip ring to extend so that it is in a negative pressure state. At this time, the annular airbag connected through the airway will deflate, avoiding greater friction to the annular airbag, thereby avoiding the problem that each time the rubber ring is disassembled, the cover generates greater friction to the tightly installed rubber ring, which easily affects the service life of the rubber ring.

[0008] Preferably, the supporting mechanism comprises a pressure ring, which is slidably connected to the bottom of the watch cover, and a plurality of groups of spring sheets are fixedly connected to the position between the inner wall of the watch cover and the pressure ring. The spring sheets are evenly arranged on the bottom of the watch cover to support the pressure ring, so that when the watch cover is closed, the pressure ring will press against the movement case of the mounting groove for fixation, so as to facilitate installation. Moreover, since the watch is fixed with the tension of the spring sheets as support, when the watch is hit, the movement case containing the movement compresses the spring sheets for buffering, thereby reducing the influence of the impact force generated by the impact on the movement.

[0009] Preferably, the pressure ring fits with the bottom of the movement shell, and a plurality of first positioning balls are fixedly connected to the top of the movement shell. A first positioning hole for embedding the first positioning ball is opened at a position corresponding to the first positioning ball on the inner wall of the mounting groove. By opening the first positioning hole at a position corresponding to the first positioning ball on the top of the movement shell on the inner wall of the mounting groove, the movement shell can be limited when the first positioning ball is embedded in the mounting groove to ensure the stability of its installation.

[0010] Preferably, the limiting mechanism comprises two groups of hooks, the two groups of hooks are respectively fixedly connected to two sides of the top of the cover, and blocks are provided at positions of the inner wall of the mounting groove corresponding to the hooks.

[0011] Preferably, a support block is fixedly connected to the inner wall of the mounting groove above the clamping block, an elastic telescopic rod is slidably connected to the inner wall of the support block, and one end of the elastic telescopic rod away from the support block is fixedly connected to the clamping block.

[0012] Preferably, the ends of the clamping block and the clamping hook corresponding to each other are arranged in an inclined surface, and the inclined surfaces are arranged in a staggered manner.

[0013] Preferably, when the watch cover is attached to the bottom of the watch case, the hook contacts and presses against the slip ring, and there are clamping holes on both sides of the bottom of the watch cover. By arranging hooks on both sides of the watch cover, when installing the watch cover, you only need to align the watch cover with the installation slot, push the watch cover into the installation slot, and then twist the watch cover so that the inclined surface of the hook presses against the inclined surface of the block until the plane of the hook fits with the block. The tension of the elastic telescopic rod will push the block to press against the hook, so that the watch cover is tightly attached to the bottom of the watch case, and since the second positioning ball is supported by the tension of the second spring, when you need to remove the watch cover, you only need to use a tweezer-like tool to insert it into the two clamping holes on the watch cover and twist it to remove it.

[0014] Preferably, a second positioning hole is provided on one side of the block corresponding to the hook, and a round hole is provided at the position of the hook corresponding to the second positioning hole. A second positioning ball is slidably connected to the inner wall of the round hole, and a second spring is fixedly connected to the position between the second positioning ball and the inner wall of the round hole. The second positioning ball is provided on the hook and embedded in the second positioning hole on the block to facilitate the limiting of the hook, thereby preventing the hook from detaching from the block.

[0015] The beneficial effects are: 1. The present invention arranges an annular airbag at the edge of the mounting groove at the bottom of the watch case, so that when the watch cover is closed, the squeezed annular airbag fills the gap between the watch cover and the watch case to ensure the sealing of the watch cover between the watch case and its waterproof performance. Moreover, since the annular airbag is connected to the air ring through the airway, when the watch cover is opened, the tension of the first spring pushes the sliding ring to extend so that it is in a negative pressure state. At this time, the annular airbag connected through the airway will deflate, avoiding large friction on the annular airbag, thereby avoiding the problem that the watch cover generates large friction on the tightly installed rubber ring every time the rubber ring is disassembled, which easily affects the service life of the rubber ring.

[0016] Second, the present invention evenly arranges spring sheets to support the pressure ring at the bottom of the watch cover, so that when the watch cover is closed, the pressure ring will press against the movement case of the installation groove to fix it, so as to facilitate installation. Moreover, since the watch is fixed by the tension of the spring sheets, when the watch is hit, the movement case containing the movement compresses the spring sheets for buffering, thereby reducing the impact of the impact force generated by the impact on the movement. Moreover, by providing a first positioning hole on the inner wall of the installation groove corresponding to the position of the first positioning ball on the top of the movement case, when the first positioning ball is embedded in the installation groove, the movement case can be limited to ensure its installation stability.

[0017] 3. The present invention arranges hooks on both sides of the watch cover. When installing the watch cover, it is only necessary to align the watch cover with the installation slot, push the watch cover into the installation slot, and then twist the watch cover so that the inclined surface of the hook abuts against the inclined surface of the block until the plane of the hook fits with the block. The tension of the elastic telescopic rod pushes the block to press against the hook, so that the watch cover fits tightly to the bottom of the watch case. A second positioning ball is arranged on the hook to embed into the second positioning hole on the block to facilitate the positioning of the hook, thereby preventing the hook from detaching from the block. Since the second positioning ball is supported by the second spring tension, when it is necessary to remove the watch cover, it is only necessary to insert a tweezer-like tool into the two holes on the watch cover and twist it to remove it.

DETAILED DESCRIPTION

[0021] To make the purpose, technical solution and advantages of the present invention clearer, the technical solution of the present invention will be described in detail below. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other implementation methods obtained by ordinary technicians in this field without creative work belong to the scope of protection of the present invention.

[0022] See also Figure 1 - Figure 7 As shown, the present invention provides a plastic bottom cover of a watch with horizontal waterproofness, comprising a watch case 1, a mounting groove 11 is provided in the watch case 1, a core shell 3 is arranged inside the mounting groove 11, a watch cover 2 is connected to the bottom of the mounting groove 11, a sealing mechanism is provided at the connection between the mounting groove 11 and the watch cover 2, which is used to seal the connection between the mounting groove 11 and the watch cover 2, a limiting mechanism is provided inside the mounting groove 11, which is used to fix the watch cover 2, a supporting mechanism is provided at the bottom of the watch cover 2, which is used to fix the core shell 3, the sealing mechanism comprises an annular airbag 123, the annular airbag 123 is fixedly connected to the bottom of the watch case 1 at a position at the edge of the mounting groove 11, an air ring 12 is fixedly connected to the top of the inner wall of the mounting groove 11, a plurality of air passages 124 are provided on the inner wall of the watch case 1, which are used to connect the air ring 12 with the annular airbag 123, and a slip ring 121 is slidably connected to the inner wall of the air ring 12, Multiple groups of first springs 122 are fixed to the inner wall of the air ring 12 and the slip ring 121. An annular airbag 123 is arranged at the bottom of the watch case 1 at the edge of the mounting groove 11, so that when the watch cover 2 is closed, the squeezed annular airbag 123 will fill the gap between the watch cover 2 and the watch case 1 to ensure the sealing of the watch cover 2 between the watch case 1 to ensure its waterproof performance. Moreover, since the annular airbag 123 is connected to the air ring 12 through the airway 124, when the watch cover 2 is opened, the tension of the first spring 122 pushes the slip ring 121 to extend and put it in a negative pressure state. At this time, the annular airbag 123 connected through the airway 124 will deflate, avoiding greater friction on the annular airbag 123, thereby avoiding the problem that the watch cover 2 generates greater friction on the tightly installed rubber ring each time the rubber ring is disassembled, which easily affects the service life of the rubber ring.

[0023] In this embodiment, please refer to Figure 4 , Figure 7 The supporting mechanism includes a pressing ring 22, which is slidably connected to the bottom of the watch cover 2. A plurality of sets of spring sheets 21 are fixedly connected to the position between the inner wall of the watch cover 2 and the pressing ring 22. By evenly arranging the spring sheets 21 at the bottom of the watch cover 2 to support the pressing ring 22, when the watch cover 2 is closed, the pressing ring 22 will press against the movement case 3 of the mounting groove 11 for fixing, so as to facilitate installation. Moreover, since the tension of the spring sheets 21 is used as support for fixing, when the watch is hit, the movement case 3 equipped with the movement compresses the spring sheets 21 for buffering, thereby reducing the impact of the impact force generated by the impact on the movement.

[0024] For further information, see Figure 2 , Figure 7 The pressure ring 22 fits with the bottom of the movement shell 3, and a plurality of first positioning balls 31 are fixedly connected to the top of the movement shell 3. A first positioning hole 32 for embedding the first positioning ball 31 is opened at a position corresponding to the first positioning ball 31 on the inner wall of the mounting groove 11. By opening the first positioning hole 32 at a position corresponding to the first positioning ball 31 on the top of the movement shell 3 on the inner wall of the mounting groove 11, the movement shell 3 can be limited when the first positioning ball 31 is embedded in the mounting groove 11 to ensure the stability of its installation.

[0025] For further information, see Figure 2 , Figure 3 , Figure 6 The limiting mechanism includes two groups of hooks 43, which are fixedly connected to the two sides of the top of the cover 2, respectively. A block 42 is provided at the position of the inner wall of the mounting groove 11 corresponding to the hook 43. A support block 41 is fixedly connected to the position of the inner wall of the mounting groove 11 above the block 42. The inner wall of the support block 41 is slidably connected to an elastic telescopic rod 44, and one end of the elastic telescopic rod 44 away from the support block 41 is fixedly connected to the block 42. The ends of the block 42 and the hook 43 corresponding to each other are inclined. The watch cover 2 is provided with hooks 43 on both sides thereof, and when installing the watch cover 2, it is only necessary to align the watch cover 2 with the installation groove 11, push the watch cover 2 into the installation groove 11, and then twist the watch cover 2 so that the inclined surface of the hook 43 abuts against the inclined surface of the block 42 until the plane of the hook 43 fits with the block 42, and the tension of the elastic telescopic rod 44 pushes the block 42 against the hook 43, so that the watch cover 2 fits tightly to the bottom of the watch case 1.

[0026] Also, see Figure 6When the cover 2 is attached to the bottom of the case 1, the hook 43 contacts and presses against the slip ring 121. The two sides of the bottom of the cover 2 are respectively provided with the holes 23. A second positioning hole 434 is provided on the side of the block 42 corresponding to the hook 43. A circular hole 431 is provided at the position of the hook 43 corresponding to the second positioning hole 434. A second positioning ball 432 is slidably connected to the inner wall of the circular hole 431. A second spring 433 is fixedly connected to the position between the second positioning ball 432 and the inner wall of the circular hole 431. When the cover 2 is closed, the hook 43 will squeeze the slip ring 121 to make it slide into the inner wall of the gas ring 12. , the air inside the air ring 12 is squeezed into the annular airbag 123 through the airway 124, so that the annular airbag 123 expands to fill the space between the watch case 1 and the watch cover 2 to facilitate sealing. A second positioning ball 432 is provided on the hook 43 to be embedded in the second positioning hole 434 on the block 42 to facilitate limiting the hook 43, thereby preventing the hook 43 from detaching from the block 42. Since the second positioning ball 432 is supported by the tension of the second spring 433, when it is necessary to remove the watch cover 2, it only needs to be inserted into the two holes 23 on the watch cover 2 with tweezers and twisted to remove it.

[0027] How it works When in use, by evenly arranging the spring sheets 21 at the bottom of the watch cover 2 to support the pressing ring 22, when the watch cover 2 is closed, the pressing ring 22 will press against the movement case 3 of the installation groove 11 to fix it, so as to facilitate installation. Moreover, since the tension of the spring sheets 21 is used as support for fixation, when the watch is hit, the movement case 3 with the movement installed compresses the spring sheets 21 for buffering, thereby reducing the impact of the impact force generated by the impact on the movement. By opening a first positioning ball 31 at the top of the movement case 3 on the inner wall of the installation groove 11, the movement case 3 with the movement installed can be easily fixed. By means of the positioning hole 32, when the first positioning ball 31 is embedded in the installation groove 11, the movement case 3 can be limited to ensure the stability of its installation, and by setting the hooks 43 on both sides of the watch cover 2, when installing the watch cover 2, it is only necessary to align the watch cover 2 with the installation groove 11, push the watch cover 2 into the installation groove 11, and then twist the watch cover 2 so that the inclined surface of the hook 43 is against the inclined surface of the block 42 until the plane of the hook 43 is in contact with the block 42. Due to the tension of the elastic telescopic rod 44, the block 42 is pushed against the hook 43, so that The watch cover 2 fits tightly to the bottom of the watch case 1. When the watch cover 2 is closed, the hook 43 squeezes the sliding ring 121 to make it slide into the inner wall of the air ring 12, and squeezes the air inside the air ring 12 into the annular air bag 123 through the air channel 124, so that the annular air bag 123 expands to fill the space between the watch case 1 and the watch cover 2, so as to facilitate sealing. In addition, by arranging a second positioning ball 432 on the hook 43 to embed into the second positioning hole 434 on the block 42, it is convenient to limit the hook 43, so as to prevent the hook 43 from being separated from the block 4 2, and because the second positioning ball 432 is supported by the tension of the second spring 433, when it is necessary to remove the watch cover 2, it is only necessary to use a pair of tweezers to insert the two clamping holes 23 on the watch cover 2 and twist it to remove it. Since the annular airbag 123 is connected to the air ring 12 through the air channel 124, when the watch cover 2 is opened, the tension of the first spring 122 pushes the sliding ring 121 to extend and put it in a negative pressure state. At this time, the annular airbag 123 connected through the air channel 124 will deflate, avoiding greater friction on the annular airbag 123.

[0028] The above is only a specific embodiment of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art can easily think of changes or substitutions within the technical scope disclosed by the present invention, which should be included in the protection scope of the present invention. Therefore, the protection scope of the present invention should be based on the protection scope of the claims.
