Description
Technical Field
[0001] The utility model relates to a timer, in particular to a novel rotating structure of a timer. Background Art
[0002] In the existing timer, the user rotates the knob (rotating cover) to set the timing time. Usually, the driving force of the timer movement is not large, so a certain installation gap must be maintained when installing the rotating shaft of the timer movement to ensure flexible rotation without jamming. However, the knob (rotating cover) is fitted with the rotating shaft of the timer movement through a connecting shaft of a certain length, which enlarges the installation gap of the rotating shaft of the timer movement. Inevitably, the knob (rotating cover) shakes during use. Therefore, the rotating shaft and the connecting shaft cannot be perpendicular to the scale disk of the timer, and the knob (rotating cover) will also tilt, which is likely to cause the user to misunderstand the product quality. A larger gap needs to be reserved between the knob (rotating cover) and the timer housing to avoid friction when the knob (rotating cover) rotates.
[0003] Chinese Utility Model CN2022220903167 discloses a timer knob structure with stable rotation, which can eliminate the shaking phenomenon and ensure the stable rotation of the knob. This technical solution requires ball grooves to be provided on both sides of the sliding piece, and then the balls are placed in the grooves to support the sliding piece through the balls and reduce the friction during rotation. Its overall structure is relatively complex, the assembly is cumbersome, and the production cost is relatively high, which needs to be further improved. Summary of the Utility Model

Detailed implementation manner
[0027] In order to make the purpose, technical solution and advantages of the present utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present utility model and are not used to limit the present utility model.
[0028] Embodiment 1, a novel timer rotating structure, includes a stabilizing piece 1 and a connecting shaft 2. The connecting shaft is vertically fixed at the center of the stabilizing piece and is integrally formed with the stabilizing piece. The stabilizing piece is also provided with a protruding portion.
[0029] The protruding portion is arranged on the front and back sides of the stabilizing piece ( Figure 2 the left side is the front side and the right side is the back side), the protruding portion is integrally formed with the stabilizing piece, the protruding portion on the front side of the stabilizing piece is in sliding fit with the back side (the side facing the stabilizing piece) of the front cover 11, and the protruding portion on the back side of the stabilizing piece is in sliding fit with the front side (the side facing the stabilizing piece) of the movement 12.
[0030] As Figures 1 - 4 shown, the protruding portion is an annular rib 3, the connecting shaft is the center of the rib, the surface of the rib is an arc surface, and the ribs are respectively arranged at the edge positions on the front and back sides of the stabilizing piece.
[0031] The stabilizing piece is supported by the ribs, so that the stabilizing piece always remains parallel to the back side of the front cover and the front side of the movement. If the connecting shaft wants to shake, it will be blocked by the reaction forces generated by the front cover and the movement. The connecting shaft can always be perpendicular to the front cover and the movement and does not shake, ensuring the stability of the rotation of the knob (rotating cover). At the same time, the contact surface of the arc surface is small, which can reduce the friction during sliding and make the movement rotate smoothly.
[0032] As Figure 2 shown: The connecting shaft includes an inserting post 1-1 at the front end and an I-shaped pipe 1-2 at the rear end. The inserting post extends from the center of the front side of the stabilizing piece and the knob (rotating cover) is inserted and fitted with the inserting post. The I-shaped pipe is inserted and fitted with the rotating shaft of the movement.
[0033] During the installation of Embodiment 1, as Figure 10 shown, the movement 12, the circuit board 13 and the battery 18 are embedded in the rear cover 14; the connecting shaft connected with the stabilizing piece is inserted and fitted with the rotating shaft of the movement through the I-shaped pipe; the front cover 11 is then fixed to the rear cover as a whole by screws. After the above structure is installed, the dial 15, the indicating color piece 16 and the rotating cover 17 are installed in sequence. The above installation steps are the same as those of the existing timer.
[0034] The difference between Example 2 and Example 1 is that: Figures 5 - 8 As shown, the protrusions are a plurality of convex columns 4 arranged on the front and back sides of the stabilizing plate. These convex columns are arranged in a ring shape with the connecting shaft as the center, and the surface of the convex columns is an arc surface. Figure 7 and Figure 8 As shown, the front side of the stabilizing plate is provided with 6 convex columns evenly arranged at the edge position, and the back side of the stabilizing plate is also provided with 6 convex columns evenly arranged at the edge position.
[0035] The difference between Example 3 and Examples 1 and 2 is that: Figure 9 As shown, a gasket 5 is added; the outer diameter of the gasket is compatible with the outer diameter of the stabilizer, and the hole in the center of the gasket is larger than the outer contour of the I-tube at the rear end of the connecting shaft. When installing, care should be taken not to interfere with the rotation of the I-tube. The gasket is placed between the stabilizer and the housing of the timer movement, and is bonded and fixed to the front of the movement during installation; the front of the gasket (the side facing the stabilizer) is in sliding cooperation with the protrusion. Obviously, a space for accommodating the gasket is required between the stabilizer and the housing of the timer movement. If the front of the movement is enlarged, the gasket can also be omitted.
[0036] The difference between the fourth embodiment and the first, second and third embodiments is that the protrusion is not provided on the stabilizing plate, but is provided on the back of the front cover and the front of the movement, and both the front and back of the stabilizing plate are slidably matched with the protrusion. The protrusion can be an annular convex rib provided on the back of the front cover and the front of the movement, or a plurality of annularly arranged protrusions provided on the back of the front cover and the front of the movement.
[0037] The difference between Example 5 and Example 4 is that a gasket can also be set between the stabilizer and the timer movement housing, and the front side of the gasket is provided with a convex rib or a convex column that slides with the back side of the stabilizer; the gasket is bonded and fixed to the front side of the timer movement housing.
[0038] The preferred embodiments of the present invention are shown in the accompanying drawings. However, the present invention can be implemented in many different forms and is not limited to the embodiments described in this specification. On the contrary, the purpose of providing these embodiments is to make the understanding of the disclosure of the present invention more thorough and comprehensive.
