Abstract
Description
Technical Field
[0001] This utility model belongs to the field of timer technology, and in particular relates to an anti-sway structure for a dual-axis timer. Background Technology
[0002] With the progress of the times and the development of society, washing machines with soaking functions have occupied a large market share. The advantages of such washing machines are obvious: the soaking function allows detergent to dissolve fully, resulting in a high degree of washing and good cleaning. For a washing machine to have a soaking washing function, its timer must first also have a soaking washing function. Due to the characteristics of soaking washing, the total washing time needs to be divided into several segments, generally designed to be around 35 minutes or more. This requires the timer's gear train to meet certain speed requirements and also necessitates the addition of certain components to segment the total washing time. Especially when the entire washing process is finished, the timer needs to be stopped, i.e., the escapement pendulum's swing needs to be restricted. The existing structure involves a time lever with a column passing through one of the through holes on both sides of the escapement pendulum, which then abuts against a spring on the housing to restrict the time lever. The time lever then controls the swing of the escapement pendulum. This structure is relatively complex, inconvenient to disassemble and assemble, and has low stability. Furthermore, it restricts the amplitude of the escapement pendulum's swing during operation. Summary of the Invention
[0003] The purpose of this invention is to overcome the shortcomings of the existing technology and provide a oscillation stop structure for a dual-axis timer that is easy to assemble and disassemble, has good stability, and does not limit the swing amplitude of the escapement pendulum.
[0004] The purpose of this utility model is achieved through the following technical solution: the anti-swing structure of this dual-axis timer includes a housing, a time cam, a time lever, and an escapement pendulum; both the time cam and the time lever are mounted in the housing via a rotating shaft, and the arrow block at one end of the time lever abuts against the outer peripheral wall of the time cam. An elastic unit is provided on the housing, the height of which is higher than the height of the escapement pendulum, and the elastic unit abuts against the stop block at one end of the time lever. A limiting post is provided on the escapement pendulum; when the arrow block of the time lever abuts against the outer peripheral wall of the time cam, the stop block of the time lever pushes away the elastic unit, allowing the escapement pendulum to swing freely; when the arrow block of the time lever abuts against the groove of the time cam, the stop block of the time lever abuts against the limiting post, and the elastic force of the elastic unit limits the time lever, thus stopping the escapement pendulum's swing.
[0005] The beneficial effects of this utility model are as follows: Compared with the prior art, by setting an elastic unit inside the housing and placing the height of the elastic unit higher than the height of the escapement pendulum, the anti-swing structure of the escapement pendulum is located above the escapement pendulum, which has the advantages of convenient assembly and disassembly, good stability and no restriction on the swing amplitude of the escapement pendulum.
[0006] Preferably, the elastic unit includes a column and an elastic plate. The column is integrally injection molded at the end corner inside the housing, and the height of the column is higher than the height of the escapement pendulum. The elastic plate is fixed above the column and located above the escapement pendulum, and the elastic plate abuts against the stop bar of the time lever. With the above structure, the elastic plate is easier to assemble and disassemble, and the fit stability between it and the time lever is also better.
[0007] Preferably, one end of the elastic sheet is L-shaped, and the upper end face of the column that matches the L-shaped end face is provided with an L-shaped snap-fit groove. The elastic sheet is inserted and fixed in the L-shaped snap-fit groove of the column. With the above structure, the elastic sheet is easier to assemble and disassemble, thus making it easier to replace the elastic sheet.
[0008] Preferably, the width of the other end of the elastic sheet is smaller than the width of the L-shaped end of the elastic sheet, and the other end of the elastic sheet abuts against the stop block of the time lever; with the above structure, the time lever exerts less force on the elastic sheet during the rotation of the time cam, which is more conducive to the rotation of the time cam and greatly improves the service life of the time cam.
[0009] Preferably, the elastic plate, the time lever, and the time cam are all on the same plane and located above one side of the escapement pendulum; this makes the force points between them more uniform, all on the same plane, and also makes disassembly and assembly more convenient.
[0010] Preferably, the stop bar block and the arrow bar block are distributed in an L-shape on the time lever; this ensures that the force point is always on the same plane as the swing of the time lever, and also on the same plane as the force point of the time cam, resulting in better stability.

[0015] The present invention will now be described in detail with reference to the accompanying drawings: as shown in the drawings Figures 1 to 3 As shown, this utility model includes a housing 1, a time cam 2, a time lever 3, and an escapement 4. The time cam 2 and the time lever 3 are both mounted in the housing 1 via a rotating shaft. The arrow block 31 at one end of the time lever 3 abuts against the outer peripheral wall of the time cam 2. An elastic unit 5 is provided on the housing 1. The height of the elastic unit 5 is higher than the height of the escapement 4. The elastic unit 5 abuts against the stop block 32 at one end of the time lever 3. A limiting post 41 is provided on the escapement 4. When the arrow block 31 of the time lever 3 abuts against the outer peripheral wall of the time cam 2, the stop block 32 of the time lever 3 pushes away the elastic unit 5 to realize the free swing of the escapement 4. When the arrow block 31 of the time lever 3 abuts against the groove 21 of the time cam 2, the stop block 32 of the time lever 3 abuts against the limiting post 41, and the elastic force of the elastic unit 5 limits the time lever 3 to realize the stop swing of the escapement 4.
[0016] The elastic unit 5 includes a column 51 and an elastic plate 52. The column 51 is integrally injection molded on the end corner inside the housing 1, and the height of the column 51 is higher than the height of the escapement pendulum 4. The elastic plate 52 is fixed above the column 51 and located above the escapement pendulum 4, and the elastic plate 52 abuts against the stop bar 32 of the time lever 3.
[0017] One end of the elastic sheet 52 is L-shaped, and the upper end face of the column 51, which is adapted to the L-shaped end face, is provided with an L-shaped snap-fit groove 53. The elastic sheet 52 is inserted and fixed in the L-shaped snap-fit groove 53 of the column 51.
[0018] The width of the other end of the elastic sheet 52 is smaller than the width of the L-shaped end of the elastic sheet 52, and the other end of the elastic sheet 52 abuts against the stop bar 32 of the time lever 3.
[0019] The elastic plate 52, the time lever 3, and the time cam 2 are all on the same plane and located above one side of the escapement pendulum 4.
[0020] The stop bar block 32 and the arrow bar block 31 are distributed in an L-shape on the time lever 3.
[0021] The working principle of this utility model is as follows: When the dual-axis timer is running normally, the arrow block 31 of the time lever 3 abuts against the outer peripheral wall of the time cam 2, and the time cam 2 moves in a circular motion. At this time, the stop block 32 of the time lever 3 pushes open the elastic plate 52, and the escapement pendulum 4 can swing at a normal amplitude. When the dual-axis timer stops working, the arrow block 31 of the time lever 3 abuts against the groove 21 of the time cam 2, and the time cam 2 stops rotating. At this time, the stop block 32 of the time lever 3 is reset by the elastic plate 52, and the elastic force of the elastic plate 52 abuts the stop block 32 of the time lever 3 against the limit post 41, thereby stopping the swing of the escapement pendulum 4.
[0022] The above are merely specific embodiments of this application, but the scope of protection of this application is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this application should be included within the scope of protection of this application. Therefore, the scope of protection of this application should be determined by the scope of the claims.
