Description

Technical Field

[0001] The utility model relates to the technical field of timers, in particular to a timer display panel. Background Art

[0002] A timer is a device used for timing. In daily use, the timer can be used to control the opening and closing of certain electrical appliances, or to control time so that more efficient work can be performed within a limited time.

[0003] The existing timer mainly includes a shell, a dial and a shielding plate. A rotatable shaft is arranged in the shell, one end of the shaft extends out of the shell, the dial is installed in the shell, and the shaft passes through the dial. One side of the dial is printed with numbers 0-55 and a digital scale pattern layer of a dividing line that divides the circumferential direction of the dial into 60 equal parts. The shielding plate is sleeved outside the shaft and arranged opposite to the digital scale pattern layer. The dial is provided with a slit extending from the center position of the dial in the radial direction and dividing the dial into a starting end and an end, and the slit is located at the position of the number 0 in the digital scale pattern layer.

[0004] The Chinese utility model patent with publication number CN217606248U discloses a visual timer with a night light and a clock, including a rear shell, a dial, a scale plate, a through hole, a movement, a rotating shaft, a color film, a transparent lens, a frame and a time setting knob. The dial is arranged on the front of the rear shell, the scale plate is arranged in the inner cavity of the dial, the through hole is opened in the center of the front of the scale plate, the movement is arranged on the back of the scale plate, the rotating shaft is arranged on the front of the movement, the color film is set on the outer ring of the rotating shaft and is arranged on the front of the scale plate, the transparent lens is arranged on the front of the scale plate, the frame is arranged on the edge of the front of the transparent lens, the rotating shaft passes through the through hole and extends to the front of the transparent lens, the time setting knob is arranged on the front of the rotating shaft and is set on the outer ring of the rotating shaft, and when timing is required, the time setting knob is set by rotating the rotating shaft. Turning the time setting knob causes the shielding disk (i.e., the color film described in the above scheme) to rotate on the dial, thereby achieving the purpose of timing. However, when in use, when the shielding disk is driven to rotate by the rotating shaft, the end of the shielding disk must enter the front side of the dial from the slit, and the dial and the shielding disk are both sheet structures. The end of the shielding disk and the beginning of the dial are almost on the same plane. When the shielding disk is driven to rotate by the rotating shaft, the beginning of the shielding disk is easy to collide with the end of the dial, so that the shielding disk is stuck outside the slit and cannot enter, thereby causing the timer to fail to work. Moreover, since most existing rotating shafts are cylindrical, it is difficult for workers to align the shielding disk with the dial when installing it, and it often takes multiple adjustments to meet the standard, which reduces the efficiency of assembly.

[0005] In view of this, the inventor conducted in-depth research on the above-mentioned issues, which led to the creation of this case. Utility Model Content

[0006] The utility model provides a timer display plate, aiming to solve the problems that a shielding plate of the timer is easily stuck outside a slit, causing the timer to fail to work, and the shielding plate cannot be accurately aligned with a scale plate when being installed.

[0008] A timer display plate comprises a shell, a shielding plate and a dial, wherein a rotating shaft is arranged in the shell and can rotate and pass through the shielding plate and the dial in sequence, and a digital scale pattern layer for displaying time is printed around a side of the dial facing away from the shell, with the clockwise direction of the rotating shaft being the right and the counterclockwise direction being the left, a mounting groove is concavely arranged in the shell, a placement groove is concavely arranged in the bottom wall of the right half of the mounting groove, and a step-shaped is formed between the bottom wall of the placement groove and the bottom wall of the left half of the mounting groove; the rotating shaft comprises an expanding diameter section and a contracting section convexly arranged on the top surface of the expanding diameter section, the contracting section is polygonal, a timing knob is arranged at the end of the contracting section, and the center of the shielding plate is provided with a timing knob. A mounting hole matching the shape of the contraction section is provided in the center, an arc-shaped slit is provided around the periphery of the mounting hole, one end of the arc-shaped slit is closed, and the other end is connected to a vertical slit extending from a shielding disk and dividing the shielding disk into a starting end and an end end; the shape of the dial is matched with the mounting groove, and a limiting hole is provided in the center of the dial, a strip slit extending from the dial is provided upward from the center of the limiting hole, the starting end of the shielding disk enters the dial from the strip slit in a clockwise direction, and the strip slit divides the dial into a first half area and a second half area, and a guide portion for entering the vertical slit is convex to the left on the side of the second half area close to the first half area.

[0009] Furthermore, the rear half of the placement groove is gradually inclined toward the front half.

[0010] Furthermore, based on the bottom surface of the shell, the inclination angle between the rear half and the front half of the placement groove is 10° to 20°.

[0014] Furthermore, a bonding layer for bonding with the bottom wall of the mounting groove is provided on a side of the dial facing the housing.

[0015] Furthermore, the contraction section is a regular pentagon or a regular hexagon.

[0016] From the above description of the structure of the utility model, it can be seen that the utility model has the following advantages:

[0017] The utility model provides a stepped installation groove in the shell, and sets the contraction section of the rotating shaft to a polygon, and also opens a mounting hole, an arc-shaped slit and a vertical slit that are adapted to the shape of the contraction section at the center of the shielding disk, and opens a strip slit on the dial for the shielding disk to enter, and the dial is also provided with a guide portion for entering the vertical slit. In this way, when in use, since the mounting groove is stepped, there is a certain distance between the first half area and the second half area of ​​the dial, so that the shielding disk can rotate smoothly on the dial, avoiding interference or mutual influence with the dial, and because the contraction section of the rotating shaft is multi-deformable, compared with the existing cylindrical rotating shaft, it is easier to align the shielding disk and the dial when installing them, thereby improving the efficiency during assembly.

DETAILED DESCRIPTION

[0024] The technical solution of the present utility model will be clearly and completely described below in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present utility model, rather than all of the embodiments.

[0025] Reference Figures 1 to 5A timer display plate comprises a housing 10, a shielding plate 30 and a dial 40. A rotating shaft 20 is provided in the housing 10 and can rotate and pass through the shielding plate 30 and the dial 40 in sequence. A digital scale pattern layer (not shown in the figure) for displaying time is printed around the side of the dial 40 facing away from the housing 10, such as 0-55, and scale lines are provided between adjacent numbers. A timing element (not shown) is driven by a motor (not shown in the figure) inside the housing 10 to realize the timing function. Since the internal structure of the timer is an existing well-known technology, only the improved points of this scheme will be described in detail later.

[0026] Reference Figures 1 to 5 In the present embodiment, the shielding plate 30 and the dial 40 are both elastic plastic sheets, with the clockwise direction of rotation of the rotating shaft 20 as the right and the counterclockwise direction as the left. The shell 10 is square, and a mounting groove 11 is concavely provided in the shell 10. A placement groove 12 is concavely provided in the bottom wall of the right half of the mounting groove 11. The bottom wall of the placement groove 12 and the bottom wall of the left half of the mounting groove 11 are stepped, that is, the left half of the mounting groove 11 is high and the right half is low. The rotating shaft 20 includes an expansion section 21 and a contraction section 22 convexly provided on the top surface of the expansion section 21. The contraction section 22 is any one of a regular pentagon, a regular hexagon, a regular heptagon, etc. A timing knob 50 is installed at the end of the contraction section 22. A mounting hole 31 adapted to the shape of the contraction section 22 is opened in the center of the shielding plate 30. When the shielding plate 30 is installed on the rotating shaft 20, the side thereof facing the shell 10 conflicts with the top surface of the expansion section 21.

[0027] Reference Figures 1 to 5An arc-shaped slit 32 is also provided around the outer circumference of the mounting hole 31, one end of the arc-shaped slit 32 is closed, and the other end is connected to a vertical slit 33 extending from the shielding plate 30 and dividing the shielding plate 30 into a starting end and an end. The shape of the scale plate 40 is adapted to the mounting groove 11, and a limiting hole 41 is provided at the center of the scale plate 40, and a strip slit 42 extending from the scale plate 40 is provided upward at the center of the limiting hole 41. The starting end of the shielding plate 30 enters the scale plate 40 from the strip slit in a clockwise direction, and the strip slit 42 divides the scale plate 40 into a first half area and a second half area, wherein the side of the second half area of ​​the scale plate 40 close to the first half area is protruding to the left with a guide portion for entering the vertical slit 33, In addition, a bonding layer for bonding with the bottom wall of the mounting groove 11 is provided on one side of the dial 40 facing the shell 10. Thus, when the dial 40 is bonded to the bottom wall of the mounting groove 11, since the mounting groove 11 and the placement groove 12 are stepped, there is a certain distance between the front side of the first half zone and the front side of the second half zone of the dial 40. This distance allows the starting end of the shielding plate 30 to enter and exit. In addition, the limiting portion of the second half zone of the dial 40 prevents the starting end of the shielding plate 30 from interfering with or colliding with the dial 40 when the timing knob 50 is rotated. Furthermore, since the contraction section 22 of the rotating shaft 20 is polygonal, the shielding plate 30 can be more easily aligned with the dial 40 during installation, thereby improving the efficiency of assembly.

[0028] Reference Figures 1 to 5 The rear half of the placement groove 12 is gradually inclined toward the front half. Based on the bottom surface of the shell 10, the inclination angle between the rear half and the front half of the placement groove 12 is 10° to 20°.

[0029] Reference Figures 1 to 5 The strip slit 42 includes an arc portion 421, a lower vertical portion 422, a horizontal turning portion 423 and an upper vertical portion 424 which are connected in sequence. The lower vertical portion 422 corresponds to the vertical slit 33, and the lower vertical portion 422 of the second half of the dial 40 is convexly provided with an arc-shaped guide piece 4221 to the left, and the guide piece 4221 is the above-mentioned guide portion. The first half of the dial 40 is provided with a guide groove 43 that is adapted to the shape of the guide piece 4221. Under normal circumstances, the guide piece 4221 is located in the guide groove 43. When the dial 40 is assembled into the shell 10, the guide piece 4221 conflicts with the side of the shielding plate 30 that is away from the dial 40, thereby further increasing the distance between the dial 40 and the shielding plate 30, reducing the probability of interference or collision between the dial 40 and the shielding plate 30, and avoiding the situation where the timer cannot work.

[0030] Reference Figures 1 to 5The utility model provides a stepped mounting groove 11 in the shell 10, and sets the contraction section 22 of the rotating shaft 20 to be a polygon, and also opens a mounting hole 31, an arc-shaped slit 32 and a vertical slit 33 that are adapted to the shape of the contraction section 22 at the center of the shielding plate 30, and opens a strip slit 42 for the shielding plate 30 to enter on the scale plate 40, and the scale plate 40 is also provided with a guide portion for entering the vertical slit 33. In this way, when in use, due to the stepped mounting groove 11, there is a certain distance between the first half area and the second half area of ​​the scale plate 40, so that the shielding plate 30 can rotate smoothly on the scale plate 40, avoiding collision or mutual interference with the scale plate 40. In addition, because the contraction section 22 of the rotating shaft 20 is multi-deformable, the shielding plate 30 and the scale plate 40 can be more accurately aligned when installing the two, thereby improving the efficiency during assembly.

[0031] The above is only a specific implementation method of the utility model, but the design concept of the utility model is not limited to this. Any non-substantial changes to the utility model using this concept shall be deemed as an infringement of the protection scope of the utility model.
