Description

Technical Field

[0001] This utility model relates to the field of watch blank technology, and in particular to a watch blank formed by one-piece casting. Background Technology

[0002] In the existing technology, the watch blank, as the core outer casing component of the watch, mainly functions to support and protect the movement and dial. During the watch assembly process, the dial needs to be precisely installed into the predetermined position within the watch blank. Traditional watch blank designs are usually fixed to the dial in one go. Once installed, the position and rotation angle of the dial are difficult to readjust. If there are slight deviations during assembly, or if the viewing angle and position of the dial need to be finely adjusted during subsequent use or maintenance, the existing watch blank structure cannot provide the corresponding adjustment function and lacks flexibility.

[0003] In addition, in certain specific application scenarios, such as watch testing, display, or specific process steps, it may be necessary to temporarily or semi-permanently fix the watch blank device to a workbench or bracket. Existing fixing methods are inconvenient to operate, or their fixing structure may be accidentally touched, causing the entire watch blank device to loosen or shift, affecting the stability and safety of the installation.

[0004] Therefore, this utility model proposes a one-piece cast watch blank to overcome the shortcomings of the prior art. Utility Model Content

[0005] In view of the problems in the existing technology of one-piece cast watch blanks, such as the fixed position and angle of the dial after installation, making it difficult to adjust flexibly, and the risk of accidental loosening of the installation and fixing structure, the present invention aims to provide a one-piece cast watch blank with an improved structure that can effectively solve the above problems.

[0006] This utility model provides a one-piece cast watch blank, comprising: a watch blank, a rotating column mounted on the watch blank, a mounting plate rotatable around the rotating column, and a watch dial fixed on the mounting plate; as well as an adjustment mechanism and a disassembly mechanism.

[0007] The adjustment mechanism is fixed to the mounting plate and includes a bevel gear two for inputting external operating power and a rotating rod that is connected to the dial in a transmission manner. The adjustment mechanism drives the rotating rod through the bevel gear two to adjust the rotation angle of the dial along the mounting plate.

[0008] Furthermore, the disassembly and assembly mechanism is fixed to the base of the watch blank. The disassembly and assembly mechanism includes a bidirectional threaded rod and a mounting clip. The disassembly and assembly mechanism drives the mounting clip to move by rotating the bidirectional threaded rod, so as to install and fix the one-piece cast watch blank.

[0009] Preferably, the adjusting mechanism further includes a first bevel gear, a bevel gear rod, and a bevel gear disk; the second bevel gear meshes with the first bevel gear, the first bevel gear drives the bevel gear rod to rotate, the bevel gear rod drives the bevel gear disk to rotate, and the bevel gear disk is fixedly connected to the rotating rod.

[0010] Preferably, the disassembly and assembly mechanism further includes a first movable block, a second movable block, and a connecting frame; the second movable block is threaded onto the bidirectional threaded rod, and the first movable block is slidably sleeved on the rotating column.

[0011] Preferably, the two ends of the connecting frame are respectively connected to the first movable block and the second movable block.

[0012] Preferably, when the second movable block moves along the axial direction of the bidirectional threaded rod under the drive of the bidirectional threaded rod, the first movable block moves along the rotating column through the connecting frame.

[0013] Preferably, the movement of the mounting clip is driven by the movement of both the first moving block and the second moving block.

[0014] Preferably, the rotation of the rotating column can drive the mounting plate and the dial to rotate as a whole along the dial blank, so as to adjust the position of the dial.

[0015] Preferably, the disassembly and assembly mechanism must be operated by rotating the bidirectional threaded rod to prevent the mounting clip from moving due to accidental contact.

[0016] This utility model has the following beneficial effects:

[0017] 1. This utility model solves the problem in the prior art where the position and angle of the dial are fixed after installation and difficult to adjust flexibly by setting a rotating column to drive the installation plate to rotate, and by setting an adjustment mechanism, using a second bevel gear to drive a first bevel gear, a bevel gear rod, a bevel gear disk and a rotating rod to rotate. This achieves the technical effect of being able to easily adjust the overall position of the dial and accurately adjust the rotation angle of the dial.

[0018] 2. This utility model, by setting up a disassembly and assembly mechanism, uses a rotating bidirectional threaded rod to drive the second moving block, the connecting frame, and the first moving block to move, thereby driving the mounting clamp to clamp and fix. This solves the problem of unstable structure of the fixing device in the prior art, or loosening due to accidental contact, and achieves the technical effect of reliable installation and fixation, and can effectively prevent accidental contact.

[0025] To make the objectives, technical solutions, and advantages of this utility model clearer, the technical solutions in the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the protection scope of this utility model.

[0026] Example:

[0027] Please refer to Figure 1 and Figure 2A one-piece cast watch blank includes a watch blank 1, on which a rotating column 4 is mounted. A mounting plate 5 is rotatably fitted onto the rotating column 4 and can rotate around the rotating column 4. A watch dial 6 is fixed to the mounting plate 5. The one-piece cast watch blank also includes an adjustment mechanism 2 and a disassembly mechanism 3, which are respectively provided. The adjustment mechanism 2 is fixed to the mounting plate 5 and is used to adjust the rotation angle of the watch dial 6 along the mounting plate 5. The disassembly mechanism 3 is fixed to the base of the watch blank 1 and is used to disassemble the one-piece cast watch blank. The watch blank is installed and fixed. Specifically, the adjustment mechanism 2 includes a bevel gear 23 for inputting external operating power and a rotating rod 25 that forms a transmission connection with the dial 6. The disassembly and assembly mechanism 3 includes a bidirectional threaded rod 31 and a mounting clamp 34. The adjustment mechanism 2 drives the rotating rod 25 through the bevel gear 23 to adjust the rotation angle of the dial 6. The disassembly and assembly mechanism 3 drives the mounting clamp 34 to move through the rotation of the bidirectional threaded rod 31. The rotation of the rotating column 4 can drive the mounting plate 5 and the dial 6 to rotate as a whole along the watch blank 1 to adjust the position of the dial 6.

[0028] Please refer to Figure 3 The adjustment mechanism 2 is fixed on the mounting plate 5. The adjustment mechanism 2 includes a bevel gear 23 for inputting external operating power, a bevel gear 21, a bevel gear rod 22, a bevel gear disk 24, and a rotating rod 25 that forms a transmission connection with the dial 6. The bevel gear 23 is rotatably mounted on the mounting plate 5 and meshes with the bevel gear 21. The bevel gear 21 is fixed to one end of the bevel gear rod 22. The bevel gear rod 22 is rotatably mounted on the mounting plate 5. The other end of the bevel gear rod 22 is fixedly connected to the bevel gear disk 24. The bevel gear disk 24 is fixedly connected to the rotating rod 25. The end of the rotating rod 25 is transmissionally connected to the dial 6. When the bevel gear 23 is rotated, the bevel gear 23 drives the bevel gear 21 to rotate. The bevel gear 21 drives the bevel gear rod 22 to rotate. The bevel gear rod 22 drives the bevel gear disk 24 to rotate. The bevel gear disk 24 drives the rotating rod 25 to rotate, ultimately realizing the adjustment of the dial 6 along the rotation angle of the mounting plate 5.

[0029] Further, please refer to Figure 4The disassembly and assembly mechanism 3 is fixed on the base of the watch blank 1. The disassembly and assembly mechanism 3 includes a bidirectional threaded rod 31, a first movable block 32, a second movable block 33, an mounting clip 34, and a connecting frame 35. The bidirectional threaded rod 31 is rotatably mounted on the watch blank 1. The second movable block 33 is threadedly engaged with the bidirectional threaded rod 31. The first movable block 32 is slidably sleeved on the rotating column 4. The two ends of the connecting frame 35 are respectively hinged to the first movable block 32 and the second movable block 33. The movement of the mounting clip 34 is jointly driven by the movement of the first movable block 32 and the second movable block 33. When the bidirectional threaded rod 31 is rotated, the second movable block 33 moves along the axial direction of the bidirectional threaded rod 31. The second movable block 33 drives the first movable block 32 to slide along the rotating column 4 through the connecting frame 35. The coordinated movement of the first movable block 32 and the second movable block 33 jointly drives the mounting clip 34 to move along the watch blank 1, so as to install and fix a one-piece cast watch blank. The operation of the disassembly and assembly mechanism 3 must be realized by rotating the bidirectional threaded rod 31 to prevent accidental activation.

[0030] As a preferred embodiment, please refer to Figure 1 The rotating column 4 is fixedly installed vertically at the center of the watch blank 1. The mounting plate 5 is a horizontal disc. The center hole of the mounting plate 5 is rotatably fitted onto the rotating column 4. The dial 6 is flatly fixedly connected to the upper surface of the mounting plate 5. This structure allows the mounting plate 5 to support the dial 6 and rotate around the rotating column 4, thereby adjusting the overall planar position of the dial 6.

[0031] As another preferred embodiment, please refer to Figure 3 The precision transmission structure of the adjustment mechanism 2 is defined. The second bevel gear 23 is rotatably mounted on the side wall bracket of the mounting plate 5, and the first bevel gear 21 is rotatably mounted on the top surface of the mounting plate 5. The tooth surface of the second bevel gear 23 meshes with the tooth surface of the first bevel gear 21 at a 90-degree angle. One end of the bevel gear rod 22 is coaxially fixedly connected to the first bevel gear 21. The bevel gear rod 22 is rotatably inserted inside the mounting plate 5. The other end of the bevel gear rod 22 is coaxially fixedly connected to the bevel gear disk 24. The bevel gear disk 24 is fixedly connected to the rotating rod 25. The output end of the rotating rod 25 forms a transmission connection with the edge of the dial 6, which is used to realize the adjustment of the rotation angle of the dial 6 around its own center.

[0032] As another preferred embodiment, please refer to Figure 4The clamping transmission structure of the disassembly and assembly mechanism 3 is defined. The bidirectional threaded rod 31 is rotatably mounted on the base of the blank 1 in the horizontal direction. The interior of the second movable block 33 is provided with a threaded hole that matches the thread direction of the bidirectional threaded rod 31. The second movable block 33 is threadedly fitted onto the bidirectional threaded rod 31. The inner hole of the first movable block 32 forms a sliding fit with the outer peripheral wall of the rotating column 4. The first movable block 32 can slide up and down along the axial direction of the rotating column 4. The connecting frame 35 is a rigid connecting rod. One end of the connecting frame 35 is rotatably connected to the first movable block 32, and the other end of the connecting frame 35 is rotatably connected to the second movable block 33. The input end of the mounting clamp 34 is rigidly connected to both the first movable block 32 and the second movable block 33 to achieve synchronous clamping.

[0033] As another preferred embodiment, the structural design of the disassembly and assembly mechanism 3 makes it possible to operate by using a specific tool or manually rotating one end of the bidirectional threaded rod 31. The self-locking property of the threaded pair is used to prevent the mounting clip 34 from moving or loosening due to accidental contact or vibration.

[0034] Working principle:

[0035] The rotation of the rotating column 4 can drive the mounting plate 5 to rotate along the dial blank 1 to adjust the position of the dial 6. At the same time, the rotation of the bevel gear 23 in the adjustment mechanism 2 can drive the bevel gear 21, and the rotation of the bevel gear 21 can drive the bevel gear rod 22 to rotate. At this time, the rotation of the bevel gear rod 22 can drive the bevel gear disk 24 and the rotating rod 25 to rotate, adjusting the rotation angle of the dial 6 along the mounting plate 5.

[0036] Furthermore, by rotating the bidirectional threaded rod 31 in the disassembly and assembly mechanism 3, the second movable block 33 can be moved back and forth. At this time, as the second movable block 33 moves, the first movable block 32 can be moved along the rotating column 4 through the connecting frame 35. At this time, by moving the first movable block 32 and the second movable block 33, the mounting clip 34 can be moved along the blank 1. Thus, the device is installed and fixed by moving the mounting clip 34. At the same time, this disassembly and assembly method requires the operation of the bidirectional threaded rod 31 to rotate, which can also prevent accidental contact.
