Description

Technical Field

[0001] The utility model relates to the technical field of mechanical watch movements, in particular to a double-balance wheel watch movement. Background Art

[0002] Patent No. CN218122472U discloses a double balance wheel mechanical watch movement. The utility model has a reasonable structural design and includes a double balance wheel watch movement. The bottom end of the double balance wheel watch movement is fixedly connected with a sleeve, one end of the sleeve is fixedly connected with a contraction structure, the contraction structure is internally movably connected with a clamping structure, and a through groove is provided inside the clamping structure. When the double balance wheel watch movement is fixedly connected, the extended clamping structure can be inserted into the connecting piece, and a movable ring with a through groove is provided on the outer side of the clamping structure, so that the movable ring can be rotated to drive the rotating gear meshingly connected on one side to rotate, and the rotating gear can be rotated to drive the clamping block fixedly connected on one side to rotate, and the clamping block can be rotated to extend outward through the extension port, so that the clamping block can clamp and fix the connecting piece, and the sleeve and the connecting piece can be effectively prevented from being separated, which has a certain convenience.

[0003] However, the above-mentioned existing double balance wheel mechanical watch movement completes the clamping by setting the gear to rotate and drive the clamping block to rotate. However, since the watch movement is small, the gears set are even smaller, which easily leads to increased production costs during production and is time-consuming and labor-intensive.

[0004] In order to solve the above problems, the utility model provides a double balance wheel watch movement. Utility Model Content

[0005] In view of the deficiencies in the prior art, the utility model provides a double balance wheel watch movement to solve the technical problem in the prior art that "the clamping block is driven to rotate by setting a gear to rotate, but since the watch movement is small, the set gears are even smaller, which easily leads to increased production costs during production and is time-consuming and labor-intensive."

[0006] To achieve the above objectives, the utility model is implemented through the following technical solutions: a double balance wheel movement, including a double balance wheel movement, a mounting hole is opened at the center of the double balance wheel movement, a first sleeve is fixedly connected in the mounting hole, a connecting tube is slidably connected in the first sleeve, a first gear is fixedly connected in the connecting tube, a second gear is meshingly connected to the inner surface of the first gear, a second sleeve is fixedly connected to the inner surface of the second gear, a third sleeve is slidably connected in the second sleeve, a first limit plate is fixedly connected to the lower end surface of the third sleeve, and the first limit plate is fixedly connected to the lower end surface of the first sleeve.

[0007] As a preferred technical solution of the utility model, a surface of one end of the connecting pipe is provided with a thread, the connecting pipe is slidably connected in the first sleeve, and one end of the connecting pipe is threadedly connected in the first sleeve through a thread.

[0008] As a preferred technical solution of the utility model, the upper end surface of the connecting pipe is fixedly connected with a second limit plate, and the second limit plate is arranged on the upper end surface of the first sleeve.

[0009] As a preferred technical solution of the utility model, four first fixing blocks are fixedly connected to the lower end surface of the second sleeve, and four second fixing blocks are fixedly connected to the upper end surface of the third sleeve.

[0010] As a preferred technical solution of the utility model, a first clamping rod is staggered and fixedly connected between every two of the first fixing blocks, and a second clamping rod is staggered and fixedly connected between every two of the second fixing blocks.

[0011] As a preferred technical solution of the utility model, the surfaces of the four first clamping rods are fixedly connected with first anti-slip grooves, and the surfaces of the four second clamping rods are fixedly connected with second anti-slip grooves.

[0012] The utility model provides a double balance wheel watch movement, which has the following beneficial effects:

[0013] 1. By setting the first gear and the second gear, the rotating connecting tube drives the first clamping rod to rotate and interact with the second clamping rod, so as to complete the clamping installation of the double balance wheel movement and the connecting piece. The first gear and the second gear are relatively large, and there is no need to make multiple small gears, which can reduce the increase of production cost during production, and save time and labor;

[0020] In order to make the technical problems, technical solutions and beneficial effects to be solved by the present invention more clearly understood, the present invention is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not used to limit the present invention.

[0021] Thus, a feature indicated in this specification will be used to illustrate one of the features of an embodiment of the utility model, rather than implying that each embodiment of the utility model must have the described feature. In addition, it should be noted that this specification describes many features. Although some features can be combined together to illustrate possible system designs, these features can also be used in other combinations that are not explicitly described. Thus, unless otherwise stated, the described combinations are not intended to be limiting.

[0022] The principle and structure of the present invention are described in detail below with reference to the accompanying drawings and embodiments:

[0025] Furthermore, a thread 4 is provided on the surface of one end of the connecting pipe 3 , the connecting pipe 3 is slidably connected in the first sleeve 2 , and one end of the connecting pipe 3 is threadedly connected in the first sleeve 2 through the thread 4 .

[0026] By providing the thread 4, the connecting pipe 3 can be moved up and down and placed stably;

[0027] Furthermore, a second limit plate is fixedly connected to the upper end surface of the connecting pipe 3 , and the second limit plate is arranged on the upper end surface of the first sleeve 2 .

[0028] By setting the second limiting plate, the connecting pipe 3 can be driven to rotate by the second limiting plate;

[0029] Furthermore, four first fixing blocks 8 are fixedly connected to the lower end surface of the second sleeve 6 , and four second fixing blocks 11 are fixedly connected to the upper end surface of the third sleeve 10 .
