Description

Technical Field

[0001] The utility model relates to the field of gas stove accessories, and particularly relates to an anti-misoperation structure for a timer. Background Technique

[0002] A gas stove timer is a device that can automatically control the switch of a gas stove. It cuts off or supplies gas by controlling an electromagnetic valve to achieve the function of timing the closing of the gas stove.

[0003] Currently, the normal open gears of mechanical timers with a normal open function are usually in the direction of closing the timer and then turning counterclockwise by a certain angle. Such a structure is very likely to cause users, when using, to inadvertently turn to the normal open gear when they need to close the timer in advance without achieving the closing of the timer, posing a safety hazard. Therefore, those skilled in the art have provided an anti-misoperation structure for a timer to solve the problems raised in the above background technique. Content of the Utility Model

[0004] To solve the above technical problems, the utility model provides an anti-misoperation structure for a timer, including a knob and a timer body. A knob is installed on the timer body. One end of the knob is fixedly connected to a rotating rod, and the rotating rod is inserted into the timer body. A limiting piece is installed on the timer body, and elastic bumps are provided on the limiting piece. A screwing bump is formed on one side of the rotating rod, and the screwing bump can contact the elastic bump.

[0005] Preferably: An activity circle is formed on the limiting piece, and the diameter of the activity circle is not less than the cross-sectional width of the rotating rod. A deformation groove is provided on the limiting piece on one side of the activity circle. One side of the activity circle is provided with a port communicating with the inside of the deformation groove. A deformable strip-shaped part is formed between the activity circle and the deformation groove, and one end of the strip-shaped part forms an elastic bump, and the elastic bump bends towards the inside of the activity circle.

[0006] Preferably: A plurality of limiting piece mounting holes are formed on the limiting piece, and threaded holes corresponding to the limiting piece mounting holes are provided on the timer body. The threaded holes on the timer body are also within the range of the deformation groove.

[0007] Preferably: A circular groove hole is provided at one end of the deformation groove.

[0008] Preferably: A timer mounting hole is formed inside the rotating rod, and the knob is connected to the timer body through the timer mounting hole.

[0009] Preferably: The inside of the timer mounting hole is not circular.

[0010] Preferably: The screwing bump has a radian.

[0011] Technical Effects and Advantages of the Utility Model:

[0012] The utility model is designed with elastic bumps to catch the screwing bumps inside the knob handle, so that when the user turns the knob to close it, the user can easily locate the closed position without deliberately paying attention to the positioning, thus avoiding accidental touch and facilitating the user's operation.

[0019] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0020] Please refer to Figures 1 to 4 , in this embodiment, a timer anti-accidental touch structure is provided, including a knob 1 and a timer body 2. The timer body 2 is equipped with a knob 1. One end of the knob 1 is fixedly connected to a rotating rod 11. The rotating rod 11 is inserted into the timer body 2. A limit piece 21 is installed on the timer body 2. An elastic bump 24 is provided on the limit piece 21. A screwing bump 112 is formed by a protrusion on one side of the rotating rod 11. The screwing bump 112 can contact the elastic bump 24.

[0021] During use, when the user manually turns the knob handle counterclockwise (the direction to close the timer) to reach the closed timing position, the elastic bump 24 of the limit piece 21 catches the screwing bump 112 inside the knob 11 handle, thereby preventing it from easily being turned counterclockwise to the normally open gear. If it needs to be turned to the normally open contact, an obvious jerky operating torque is required to overcome the elastic bump 24 of the limit piece 21 to turn it to the normally open gear.

[0022] In a further embodiment, referring to Figures 3 to 4 , an activity circle 23 is formed on the limiting piece 21, the diameter of the activity circle 23 is not less than the cross-sectional width of the rotating rod 11, a deformation groove 25 is arranged on the limiting piece 21 at one side of the activity circle 23, one side of the activity circle 23 is provided with a port communicating with the inside of the deformation groove 25, a deformable strip-shaped part is formed between the activity circle 23 and the deformation groove 25, one end of the strip-shaped part forms an elastic bump 24, and the elastic bump 24 bends towards the inside of the activity circle 23. The activity circle 23 provides a space for the rotation of the screwing bump 112, the deformation groove 25 provides a space for the deformation of the strip-shaped part, and the elastic bump 24 faces towards the inside of the activity circle 23 to hinder the rotation of the screwing bump 112.

[0023] In a further embodiment, referring to Figures 3 to 4 , a plurality of limiting piece mounting holes 22 are formed on the limiting piece 21, the timer body 2 is provided with threaded holes corresponding to the limiting piece mounting holes 22, and the timer body 2 is further provided with threaded holes within the range of the deformation groove 25. The limiting piece 21 is fixedly mounted on the locator body 2 by screwing a bolt through the limiting piece mounting holes 22 into the threaded holes.

[0024] In a further embodiment, referring to Figures 3 to 4 , one end of the deformation groove 25 is provided with a circular groove hole. By providing a circular hole groove at one end of the deformation groove 25, the width of the connection between the deformable strip-shaped part and the whole limiting piece 21 becomes narrower, so that a relatively small force is maintained during deformation to deform the strip-shaped part, ensuring that after the screwing bump is hindered by the elastic bump 24, its elastic deformation can be easily achieved to switch to the normally open contact.

[0025] In a further embodiment, referring to Figures 1 to 3 , a timer mounting hole 111 is arranged inside the rotating rod 11, and the knob 1 is connected to the timer body 2 through the timer mounting hole 111.

[0026] In a further embodiment, referring to Figure 2 , the inside of the timer mounting hole 111 is not circular. By the inside of the mounting hole 111 not being circular, when the rotating rod 111 is connected to the timer body 2, the internal parts of the timer body 2 can be driven to rotate by the rotating rod 111. If it is circular, relative rotation will occur, resulting in the rotating rod 111 being unable to drive the internal parts of the timer body 2 to rotate.

[0027] In a further embodiment, referring to Figures 2 to 3 , the screwing bump 112 has a radian. By the outer side of the screwing bump 112 being a radian, the resistance can be reduced when rotating to the normally open state.

[0028] Although embodiments of the present invention have been shown and described, it will be understood by those of ordinary skill in the art that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principles and spirit of the present invention, and the scope of the present invention is defined by the appended claims and their equivalents.
