DETAILED DESCRIPTION
[0025] In order to make the technical means, creative features, objectives and effects achieved by the present invention easier to understand, the present invention is further described below in conjunction with specific embodiments and drawings. However, the following embodiments are only preferred embodiments of the present invention and are not exhaustive. Based on the embodiments in the implementation manner, other embodiments obtained by those skilled in the art without creative work are all within the scope of protection of the present invention.
[0026] The specific embodiments of the present utility model are described below with reference to the accompanying drawings.
[0027] Example 1
[0028] like Figure 1 As shown, in this embodiment, a new timer movement with self-limiting function is proposed, which includes a mounting shaft 120; the mounting shaft 120 is provided with a driven gear 160 coaxial with the axis of the mounting shaft 120, a first ring 130, a second ring 140 and a limiting ring 150 from top to bottom; the driven gear 160, the first ring 130 and the second ring 140 are sleeved on the mounting shaft 120, and the driven gear can drive the first ring 130 and the second ring 140 to rotate around the axis of the mounting shaft 120.
[0029] like Figure 2 As shown; a notch 1301 is provided on the first ring 130, and a first protrusion 1401 is provided on the upper end surface of the second ring 140 to be engaged with the notch 1301. The driven gear 160 first drives the first ring 130 to rotate around the axis of the mounting shaft 120, and then the second ring 140 follows the rotation of the first ring 130 through the cooperation of the first protrusion 1401 and the notch 1301.
[0030] At the same time, a second protrusion 1402 is provided on the lower end surface of the second ring 140 , and the first protrusion 1401 and the second protrusion 1402 are staggered.
[0031] The second protrusion 1402 extends into the limiting ring 150 and can rotate around the axis of the installation shaft 120. A blocking portion 1501 located on the rotation path of the second protrusion 1402 is embedded in the limiting ring 150. When the first ring 130 rotates axially or the first ring 130 and the second ring 140 rotate axially together, the limiting ring 150 is stationary relative to the installation shaft 120.
[0032] In the initial state of the movement, the second protrusion 1402 abuts against the right end wall of the blocking portion 1501. When the timing state of the movement starts, the second protrusion 1402 rotates around the mounting shaft 120 until it abuts against the left end wall of the blocking portion 1501. After the movement starts timing, the gear slowly drives the first ring 130 and the second ring 140 to rotate. When the second protrusion 1402 rotates until it abuts against the right end wall of the baffle, the timing ends.
[0033] like Figure 3-6 The mounting shaft 120 shown is installed on the housing 110, and one end of the mounting shaft 120 extends out of the housing 110. A gear set 170 and a driving part 200 are provided in the housing 110 for driving the driven gear 160 to rotate. The gear set 170 and the driving part 200 drive the gear set 170 to rotate (the gear set is a common technology and will not be described here), thereby realizing the clockwise and counterclockwise rotation of the driven gear 160.
[0034] like Figure 7 To prevent the movement of the timer from shifting in position when the movement is at rest, causing the second protrusion 1402 to leave the right end wall of the blocking portion 1501 and leading to inaccurate timing, first and second slots 1302 and 1403 are provided on the first and second rings 130 and 140, respectively. A linear switch 180 and a rocker 190 for pressing the linear switch 180 are provided on the housing 110. The rocker 190 screws into the first and second slots 1302 and 1403. Rocker 190 limits the movement in its non-operating state, improving its timing accuracy. When the first and second slots 1302 and 1403 become misaligned, they are screwed out, allowing the movement to resume operation.
[0035] Example 2
[0036] In the movement of Example 1, the blocking portion 1501 occupies a certain space on the rotation path of the second protrusion 1402, resulting in a maximum rotation angle of the second protrusion 1402 being less than 360°.
[0037] Therefore, in this embodiment, the size of the first protrusion 1401 is set to be smaller than the size of the notch 1301, so that the first protrusion 1401 extends into the notch 1301 and can only contact one end of the notch 1301 at the same time, and the movement loss caused by the blocking part 1501 is compensated by the movement distance of the first protrusion 1401 in the notch 1301.
[0038] When the first protrusion 1401 moves from one end of the notch 1301 to the other end of the notch 1301, the distance moved by the second protrusion 1402 is the same as the length of the blocking portion 1501 in the direction of the rotation path, so that the first ring 130 and the second ring 140 on the movement can rotate 360°.
[0039] The above shows and describes the basic principles, main features, and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited to the above embodiments. The above embodiments and descriptions are merely preferred examples of the present invention and are not intended to limit the present invention. Various changes and improvements may be made to the present invention without departing from the spirit and scope of the present invention, and such changes and improvements fall within the scope of the present invention. The scope of protection claimed in the present invention is defined by the appended claims and their equivalents.
