Description

Technical Field

[0001] The utility model relates to the technical field of wall clock hanging, in particular to a wall clock hanging connection device with a horizontal calibration structure. Background Art

[0002] A wall clock is a common timekeeping device, usually hung on a wall or other bracket. A wall clock consists of a clock movement and a casing, and can display time and timekeeping functions through mechanical gears, quartz crystals or other technologies.

[0003] For example, a gear wall clock with publication number CN208334927U comprises a dial and a pointer. The dial is provided with a hollow marking hole for indicating the hourly time, and a raised portion is provided on the outer edge of the dial. The decorative performance of the wall clock is improved by the hollow marking hole on the dial and the raised portion on the outer edge of the dial. At the same time, through a fixing piece movably connected to the dial, the dial can be hung or placed upright. The gravity balance block on the dial can be used in conjunction with the fixing piece so that the dial can always be turned to the correct position, thereby increasing the accuracy of the wall clock.

[0004] The above-mentioned comparative document uses a fixing part movably connected to the dial so that the dial can be hung or placed upright. The installation of the wall clock on the wall or bracket may cause angle changes due to environmental factors and structural differences, which not only affects the aesthetics of the wall clock, but may also lead to increased time errors in some specially designed wall clocks. Utility Model Content

[0005] The purpose of the utility model is to provide a wall clock hanging connection device with a horizontal calibration structure to solve the problem that the installation of the wall clock on the wall or the bracket in the above-mentioned background technology may cause angle changes due to environmental factors and structural differences, which not only affects the aesthetics of the wall clock, but also may cause the increase of time error in some specially designed wall clocks.

[0006] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a wall clock hanging connection device with a horizontal calibration structure, comprising a fixed plate, a dial, and a pointer group, wherein the dial is located outside the fixed plate, and the pointer group is arranged in the middle of the dial, a clock core is fixedly connected in the middle of the side of the fixed plate away from the dial, and the output end of the clock core is transmitted between the fixed plate and the dial and fixedly connected to the pointer group;

[0007] A protective shell is fixedly connected to the outer side of the fixed disk, and the clock core is located inside the protective shell, a fixed ring is fixedly connected to one side of the fixed disk, and a balancing structure is provided on the outer side of the protective shell, the balancing structure is provided with a gear ring, a driven gear is meshed on the outer side of the gear ring, and a hook is fixedly connected to one side of the driven gear, a centrifugal shaft is fixedly connected to the eccentric part of one side of the gear ring 7, and a moving ring is slidably connected to the outer side of the centrifugal shaft, the lower end of the moving ring is fixedly connected to a connecting rod, and the lower end of the connecting rod is fixedly connected to a counterweight block.

[0008] Furthermore, a limiting ring is provided on the side of the fixing ring away from the fixing disk, and the gear ring is located between the limiting ring and the fixing disk, and the gear ring is rotatably connected to the outside of the fixing ring, and the gear ring is located inside the protective shell.

[0009] Furthermore, the driven gear is rotatably connected to one side of the fixed plate, and the hook penetrates the top of the protective shell and extends to the outside of the top of the protective shell.

[0010] Furthermore, a fixed shaft is fixedly connected to the bottom of one side of the fixed plate, and the fixed shaft is located outside the gear ring, and the outer side of the fixed shaft is rotatably connected to the middle of the inner side of the connecting rod.

[0011] Furthermore, the centrifugal shaft drives the moving ring to slide along with it, and the connecting rod and the moving ring move around the fixed shaft to form a crank-connecting rod mechanism.

[0012] Furthermore, the counterweight block is made of metal, and the connecting rod passes through the top of the protective shell and extends to the outside of the bottom of the protective shell.

[0013] Furthermore, the counterweight block rotates around a fixed axis through a connecting rod to form a swing structure.

[0014] Compared with the prior art, the beneficial effects of the utility model are:

[0015] The wall clock hanging connection device with a horizontal calibration structure is provided with a balancing structure. When the wall clock is hung vertically, the hook component inside it is in a vertical state with the fixed plate component, and the counterweight block and the hook are on the same horizontal line. If the fixed plate cannot maintain a vertical state with the hook, the counterweight block will be forced to rotate and adjust around the fixed axis due to its heavy deadweight, so that the counterweight block gradually tends to a position vertical to the ground.

[0016] Furthermore, during this process, the rotation of the connecting rod will drive the moving ring to rotate around the fixed axis and cause the centrifugal shaft to slide inside the moving ring. As the centrifugal shaft moves, it will drive the gear ring to rotate. When the gear ring rotates, it will form a linkage with the driven gear. Since the driven gear and the outer side of the gear ring are meshed with each other, the driven gear will drive the hook to rotate around it, thereby reducing the internal angle between the hook and the connecting rod.

[0017] Furthermore, since the rotation of the hook makes it impossible to maintain perpendicularity with the fixed plate, the hook will maintain a certain angle with the fixed plate through the rotation of the gear ring. As the counterweight rotates in a direction perpendicular to the ground, the hook and the counterweight will rotate in the opposite direction, causing the center of gravity of the wall clock to move toward the outer angle direction of the hook and the connecting rod, thereby keeping the center of gravity of the fixed plate stable when moving and keeping it parallel to the ground.

[0025] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0026] In a further preferred embodiment of the present invention, Figure 1 - Figure 6As shown, a protective shell 5 is fixedly connected to the outer side of the fixed disk 1, and the clock core 4 is located inside the protective shell 5, a fixed ring 6 is fixedly connected to one side of the fixed disk 1, and a balancing structure is provided on the outer side of the protective shell 5, and a gear ring 7 is provided on the balancing structure, a driven gear 8 is meshed on the outer side of the gear ring 7, and a hook 9 is fixedly connected to one side of the driven gear 8, a centrifugal shaft 10 is fixedly connected to the eccentric part of one side of the gear ring 7, and a moving ring 11 is slidably connected to the outer side of the centrifugal shaft 10, a connecting rod 12 is fixedly connected to the lower end of the moving ring 11, and a counterweight 13 is fixedly connected to the lower end of the connecting rod 12; a limiting ring is provided on the side of the fixed ring 6 away from the fixed disk 1, and the gear ring 7 is located between the limiting ring and the fixed disk 1, and the gear ring 7 is rotatably connected to the fixed ring 6, and the gear ring 7 is located inside the protective shell 5; the driven gear 8 is rotatably connected to one side of the fixed disk 1, and the hook 9 penetrates the top of the protective shell 5 and extends to the outside of the top of the protective shell 5; a fixed shaft 14 is fixedly connected to the bottom of one side of the fixed disk 1, and the fixed shaft 14 is located outside the gear ring 7, and the outside of the fixed shaft 14 is rotatably connected to the middle of the inside of the connecting rod 12; the centrifugal shaft 10 drives the moving ring 11 to slide with it, and the connecting rod 12 and the moving ring 11 move around the fixed shaft 14 to form a crank connecting rod mechanism; the counterweight 13 is made of metal, and the connecting rod 12 penetrates the top of the protective shell 5 and extends to the outside of the bottom of the protective shell 5; the counterweight 13 rotates around the fixed shaft 14 through the connecting rod 12 to form a swinging structure;

[0027] When the wall clock is hung vertically, the hook 9 inside is in a vertical state with the fixed plate 1, and the counterweight 13 is on the same horizontal line with the hook 9. If the fixed plate 1 cannot maintain a vertical state with the hook 9, the counterweight 13 has a large deadweight, which will cause the connecting rod 12 to rotate and adjust around the fixed axis 14, so that the counterweight 13 gradually tends to a position vertical to the ground.

[0028] During this process, the rotation of the connecting rod 12 will drive the moving ring 11 to rotate around the fixed shaft 14, and cause the centrifugal shaft 10 to slide inside the moving ring 11. As the centrifugal shaft 10 moves, it will drive the gear ring 7 to rotate. When the gear ring 7 rotates, it will form a linkage with the driven gear 8. Since the driven gear 8 is meshed with the outer side of the gear ring 7, the driven gear 8 will drive the hook 9 to rotate around it, thereby reducing the internal angle between the hook 9 and the connecting rod 12.

[0029] Since the rotation of the hook 9 makes it impossible to maintain perpendicularity with the fixed plate 1, the hook 9 will maintain a certain angle with the fixed plate 1 through the rotation of the gear ring 7. As the counterweight 13 rotates in a direction perpendicular to the ground, the hook 9 and the counterweight 13 will rotate in the opposite direction, so that the center of gravity of the wall clock moves toward the outer angle direction of the hook 9 and the connecting rod 12, thereby keeping the center of gravity of the fixed plate 1 stable when moving, so that it remains parallel to the ground.
