Description

Technical Field

[0001] The utility model belongs to the technical field of clocks and watches, and particularly relates to a mechanical clock movement. Background Art

[0002] The core of a mechanical clock is its movement. The movement's internal structure, including the mainspring's power transmission mechanism, the travel transmission mechanism, and the timekeeping control mechanism, constitutes the core technology of a mechanical clock. The movement is mounted within the clock case, with the dial, located at the center of the movement's front plate, housing the minute and hour hands. The pendulum, part of the escapement's speed-regulating mechanism, controls the clock's travel accuracy by adjusting its reciprocating frequency. Due to the exposed surface of the transmission mechanism, the external hour hand requires lubrication to maintain smooth movement. In existing technology, this is achieved by adding a paste lubricant along the drive shaft core. However, this approach suffers from poor penetration of the paste lubricant due to the traditional movement's transmission structure, which is located at the drive shaft center and the gap between the drive shafts. Summary of the Invention

[0004] The utility model provides the following technical solution: a mechanical clock movement, including a transmission mechanism, wherein a pointer transmission shaft, a transmission adapter assembly, and a threaded assembly seat are provided on the top of the transmission mechanism, the pointer transmission shaft passes through the transmission adapter assembly and the threaded assembly seat, and the pointer transmission shaft is engaged with the output end of the transmission mechanism, the transmission adapter assembly is fixedly connected to the threaded assembly seat, the threaded assembly seat is threadedly connected to the transmission mechanism, the pointer transmission shaft is fixedly connected to a rotating sleeve, and a linkage bearing is fixedly connected to the outer side of the rotating sleeve;

[0005] The transmission adapter assembly includes a connecting ring sleeve and a fixed ring sleeve, the connecting ring sleeve and the fixed ring sleeve are symmetrically distributed, a positioning clamp is fixedly connected to the bottom of the connecting ring sleeve, the fixed ring sleeve is provided with two groups of symmetrically distributed clamping grooves, the positioning clamp is engaged with the clamping grooves, and the linkage bearing is rotatably connected to the inner sides of the connecting ring sleeve and the fixed ring sleeve.

[0006] The transmission mechanism is fixedly connected to a vertical limiting sleeve, a threaded sleeve is fixedly connected to the inner side of the vertical limiting sleeve, and the threaded assembly seat is threadedly fixed to the threaded sleeve.

[0007] Wherein, the bottom end of the rotating sleeve passes through the threaded assembly seat, the threaded sleeve and the vertical limiting sleeve in sequence, and the bottom end of the rotating sleeve extends to the inner side of the transmission mechanism.

[0008] Wherein, anti-slip rotation grooves are provided on the inner sides of the connecting ring sleeve and the fixing ring sleeve, and the linkage bearing is rotatably connected to the anti-slip rotation grooves.

[0009] Wherein, two locking protrusions adapted to the protrusion grooves are fixedly connected to the inner side of the positioning clamp, and the locking protrusions are snap-connected to the inner side of the protrusion grooves.

[0010] The beneficial effects of the present invention are as follows: the linkage bearing is guided by the separately arranged connecting ring sleeve and the fixed ring sleeve, so that the rotating sleeve can be connected to the internal driving member of the transmission mechanism by the linkage bearing. At the same time, during regular maintenance and lubrication, the mutual engagement of the positioning clamp and the clamping groove can be released to expose the guiding space for the linkage bearing formed by the connecting ring sleeve and the fixed ring sleeve to the outside, and then the gap between the connecting ring sleeve and the fixed ring sleeve can be directly filled with paste lubricant, or the rotating sleeve can be directly pulled out from between the connecting ring sleeve and the fixed ring sleeve to the outside for lubrication, which is convenient for movement maintenance while not affecting the normal transmission efficiency of the transmission mechanism to the rotating sleeve.

DETAILED DESCRIPTION

[0017] See also Figure 1-Figure 4The utility model provides the following technical solutions: a mechanical clock movement, including a transmission mechanism 1, a pointer transmission shaft 2, a transmission adapter component 3, and a threaded assembly seat 4 are arranged on the top of the transmission mechanism 1, the pointer transmission shaft 2 passes through the transmission adapter component 3 and the threaded assembly seat 4, and the pointer transmission shaft 2 is engaged with the output end of the transmission mechanism 1, the transmission adapter component 3 is fixedly connected to the threaded assembly seat 4, the threaded assembly seat 4 is threadedly connected to the transmission mechanism 1, the pointer transmission shaft 2 is fixedly connected to a rotating sleeve 21, and a linkage bearing 22 is fixedly connected to the outer side of the rotating sleeve 21.

[0018] In this embodiment, in order to solve the operational inconvenience caused by the need to disassemble the entire machine for lubrication and maintenance of the traditional movement transmission structure, the utility model proposes a mechanical clock movement, which solves this technical problem by providing a linkage bearing 22, a transmission adapter component 3 and a threaded assembly seat 4. Among them, since the improvement content of the present invention is not the transmission connection part between the pointer transmission shaft 2 and the transmission mechanism 1, the pointer transmission shaft 2 is connected to the output end of the inner driving member of the transmission mechanism 1 by opening an inner hexagonal hole at the bottom of the rotating sleeve 21 to realize the driving of the pointer transmission shaft 2. Since this part is the existing technical content, in this embodiment, the transmission principle will not be repeated.

[0019] The transmission adapter assembly 3 includes a connecting ring sleeve 31 and a fixed ring sleeve 32. The connecting ring sleeve 31 and the fixed ring sleeve 32 are symmetrically distributed. A positioning clamp 33 is fixedly connected to the bottom of the connecting ring sleeve 31. The fixed ring sleeve 32 is provided with two groups of symmetrically distributed convex grooves 34. The positioning clamp 33 is engaged with the convex grooves 34, and the linkage bearing 22 is rotatably connected to the inner side of the connecting ring sleeve 31 and the fixed ring sleeve 32.

[0020] In this embodiment, when in use, the connecting ring 31 and the fixing ring 32 are in a combined state through the adaptive engagement of the positioning clamp 33 and the protruding retaining groove 34. This maintains the linkage bearing 22 integral with the connecting ring 31 and the fixing ring 32, while the cylindrical structure formed by the connecting ring 31 and the fixing ring 32 provides rotational guidance for the linkage bearing 22. During regular maintenance and lubrication, the mutual engagement of the positioning clamp 33 and the protruding retaining groove 34 can be released to expose the guide space for the linkage bearing 22 formed by the connecting ring 31 and the fixing ring 32 to the outside, allowing the gap between the connecting ring 31 and the fixing ring 32 to be directly filled with a paste lubricant.

[0021] The transmission mechanism 1 is fixedly connected with a vertical limiting sleeve 11 , the inner side of the vertical limiting sleeve 11 is fixedly connected with a threaded sleeve 12 , and the threaded assembly seat 4 is threadedly fixed with the threaded sleeve 12 .

[0022] The bottom end of the rotating sleeve 21 passes through the threaded assembly seat 4 , the threaded sleeve 12 and the vertical limiting sleeve 11 in sequence, and the bottom end of the rotating sleeve 21 extends to the inside of the transmission mechanism 1 .

[0023] Anti-slip rotation grooves 35 are formed on the inner sides of the connecting ring sleeve 31 and the fixing ring sleeve 32 , and the linkage bearing 22 is rotatably connected to the anti-slip rotation grooves 35 .

[0024] In this embodiment, the threaded assembly seat 4 is fixedly connected to the upper end of the vertical limiting sleeve 11 by being threadedly connected to the threaded sleeve 12. The vertical limiting sleeve 11, the threaded sleeve 12 and the threaded assembly seat 4 are all hollow structures. After the rotating sleeve 21 passes through the connecting ring sleeve 31, the fixed ring sleeve 32, the threaded assembly seat 4 and the threaded sleeve 12 in sequence and extends to the interior of the transmission mechanism 1, the output end of the driving member arranged on the inner side of the transmission mechanism 1 is engaged with the hexagonal hole opened at the bottom of the rotating sleeve 21 to realize the transmission of the pointer transmission shaft 2. During the transmission process, since the linkage bearing 22 is placed in the anti-slip rotation groove 35 opened between the connecting ring sleeve 31 and the fixed ring sleeve 32, the connecting ring sleeve 31 and the fixed ring sleeve 32 do not affect the normal transmission operation of the pointer transmission shaft 2.

[0025] In this embodiment, the threaded assembly seat 4 and the threaded sleeve 12 can be removed to separate the pointer transmission shaft 2 from the transmission mechanism 1, which is convenient for the installation of the pointer transmission shaft 2 and subsequent replacement.

[0026] Two locking protrusions 331 adapted to the protruding grooves 34 are fixedly connected to the inner side of the positioning clamp 33 , and the locking protrusions 331 are engaged with the inner side of the protruding grooves 34 .

[0027] In this embodiment, after the positioning clamp 33 is engaged with the outside of the fixed ring sleeve 32, the locking protrusion 331 is engaged with the inside of the protrusion groove 34. The adaptive engagement of the protrusion groove 34 and the locking protrusion 331 increases the connectivity of the connecting ring sleeve 31 and the fixing ring sleeve 32 after they are combined, avoiding the generation of gaps when the connecting ring sleeve 31 and the fixing ring sleeve 32 guide the rotation of the linkage bearing 22, thereby ensuring stability in use.

[0028] The working principle of the present utility model is as follows: when lubricating the components during maintenance, the mutual engagement between the positioning clamp 33 and the convex groove 34 can be released by pulling the fixing ring sleeve 32, so that the fixing ring sleeve 32 and the connecting ring sleeve 31 are separated, and the guiding space for the linked bearing 22 formed by the connecting ring sleeve 31 and the fixing ring sleeve 32 is exposed to the outside, and then the gap between the connecting ring sleeve 31 and the fixing ring sleeve 32 can be directly filled with paste lubricant, or the rotating sleeve 21 can be directly pulled out from between the connecting ring sleeve 31 and the fixing ring sleeve 32 to the outside for lubrication, which is convenient for the maintenance of the movement without affecting the normal transmission efficiency of the transmission mechanism 1 on the rotating sleeve 21.
