Description

TECHNICAL FIELD

[0001] The utility model belongs to the technical field of pointer clock, concretely relates to an adjusting device of pointer clock. BACKGROUND

[0002] In the process of producing pointer clock, time adjustment and calibration become an indispensable link. When adjusting the time of the pointer clock, the time is usually adjusted by rotating the time knob. If the time span is large, such as adjusting from an arbitrary time point to another time point far apart, especially from zero point to zero point as required in production inspection, that is, the debugging span of 12 hours, the number of rotating knobs will increase accordingly, and the time spent will naturally be prolonged.

[0003] The traditional time adjustment and calibration work relies on manual operation. Since the time and alarm clock settings need to start from zero point and return to zero point to complete a complete verification cycle, such operation will undoubtedly greatly reduce the work efficiency in the case of manual time adjustment. Therefore, how to improve this link, reduce the time and effort of manual operation, and improve the production efficiency has become a problem to be solved in the field of pointer clock production.

[0021] In order to make the purpose, technical scheme and advantages of the present application more clear, the technical scheme of the present application will be described in detail below in combination with the specific embodiments of the present application and the corresponding drawings. Obviously, the described embodiments are only a part of the embodiments of the present application, but not all the embodiments. Based on the embodiments in the present application, all the other embodiments obtained by those skilled in the art without creative labor fall within the scope of protection of the present application.

[0022] One embodiment of the adjusting device of the pointer clock of the present application, as shown in the figure, comprises a device support 1 which serves as a support, an installation space 11 is formed on the device support 1, Figs. 1-3 and a device support 1 which serves as a support, an installation space 11 is formed on the device support 1,

[0023] A first rotating shaft 2 is transversely arranged in the mounting space 11 and rotatably connected to the mounting space 11 through bearings at both ends of the first rotating shaft 2. One end of the first rotating shaft 2 extends out of the mounting space 11 and is detachably connected to a hand wheel 3. The hand wheel 3 is rotatable to drive the first rotating shaft 2 to rotate relative to the device support 1.

[0024] The first rotating shaft 2 is fixedly connected to a first bevel gear 4.

[0025] A second rotating shaft 5 is longitudinally arranged and rotatably connected to the device support 1. The second rotating shaft 5 is rotatably connected to the device support 1 through a bearing at the middle part of the second rotating shaft 5. The lower end of the second rotating shaft 5 extends into the mounting space 11, and the upper end of the second rotating shaft 5 extends out of the device support 1. The lower end of the second rotating shaft 5 is connected to a second bevel gear 6 that is engaged with the first bevel gear 4. The tooth number ratio of the first bevel gear 4 to the second bevel gear 6 is 1:2, 1:3 or 1:4, which can be set according to actual needs.

[0026] The upper end of the second rotating shaft 5 is connected to a limiting rod 7 made of rubber. The top of the limiting rod 7 is provided with a limiting groove 71 that is adapted to the pointer knob of the pointer clock.

[0027] In operation, the device support 1 is fixed on a workbench. The pointer knob of the pointer clock is limited and fixed relative to the limiting groove 71 of the limiting rod 7. At this time, the pointer clock needs to be held by hand. Then, the hand wheel 3 is rotated to drive the first rotating shaft 2 to rotate. The rotation of the first rotating shaft 2 is realized through the engagement of the first bevel gear 4 and the second bevel gear 6. The rotation of the limiting rod 7 is realized to quickly adjust the pointer knob of the pointer clock and realize the quick adjustment time of the pointer clock.

A screw rod 82 is longitudinally arranged on the connecting frame 81 and is threadedly connected to the connecting frame 81. One end of the screw rod 82 is connected to a pressing block 83, which is located in the connecting frame 81 and forms a clamping space with the connecting frame 81. The other end of the screw rod 82 extends out of the connecting frame 81 and is connected to a cross rod 84 arranged transversely. The clockwise or counterclockwise rotation of the cross rod 84 drives the clamping space formed between the pressing block 83 and the connecting frame 81 to become smaller or larger.

[0030] When connected, the clamping space is matched with the workbench, and then the pressing is adjusted through the cross rod 84, so that the device support 1 is connected with the workbench.

[0031] The operation process of the embodiment is as follows: the clamping space formed between the pressing block 83 and the connecting frame 81 is connected with the workbench, the cross rod 84 is screwed, and the device support 1 is fixed on the workbench.

[0032] Take out the pointer clock, the clock face of the pointer clock faces up, the pointer knob of the pointer clock faces down, the pointer knob that needs to adjust time is aligned to the limiting slot 71 of the limiting rod 7, and the pointer knob and the limiting slot 71 are limited to each other;

[0033] Hold the pointer clock, do not loosen between the pointer knob and the limiting slot 71, and rotate the hand wheel 3 in the positive direction or the reverse direction to quickly adjust the time, which is simple in operation and high in efficiency.
