Description
Technical Field
[0001] The utility model belongs to the technical field of switches, and in particular relates to a switch for preventing misoperation. Background Art
[0002] The word switch means to open and close. It also refers to an electronic component that can open a circuit, interrupt the current or make it flow to another circuit. The most common switch is an electromechanical device that can be operated by a person, with one or more electronic contacts. The "closed" contact means that the electronic contact is conductive and allows current to flow; the "open" switch means that the electronic contact is not conductive and forms an open circuit, which does not allow current to flow.
[0003] In order to prevent erroneous operation, existing switches usually have a protective shell installed on the outside of the switch to prevent direct contact with the switch when not in use. However, the protective shell needs to be opened when in use and then the switch is operated. After the switch operation is completed, the protective shell needs to be closed, otherwise the protective shell cannot play a protective role. However, existing users usually forget to close the protective shell after the second step, that is, the switch operation is completed, so the protective shell cannot play a protective role and prevent erroneous operation. Therefore, there is room for improvement. Utility Model Content

DETAILED DESCRIPTION
[0022] In order to enable those skilled in the art to better understand the present invention, the technical solution of the present invention is further described below in conjunction with the accompanying drawings and embodiments.
[0023] Example 1: Figure 1-6 As shown, a switch for preventing misoperation of the utility model comprises a switch housing 1, switch buttons 11 are installed on the left and right sides of the switch housing 1, a mounting groove matching the switch button 11 is provided inside the switch housing 1, L-shaped sliders 12 are slidably connected to the left and right sides of the switch housing 1, and a switch cover 13 matching the switch housing 1 is slidably connected to the two L-shaped sliders 12, and sliding grooves 14 slidably connected to the L-shaped sliders 12 are provided on both sides of the switch housing 1, and a first spring 15 is installed between the sliding groove 14 and the L-shaped slider 12, a circular plate 16 is slidably connected to the switch housing 1 up and down, a plurality of second springs 17 are installed at the lower end of the circular plate 16, a trapezoidal locking block 18 is installed at the upper end of the circular plate 16, and a locking hole 19 matching the trapezoidal locking block 18 is provided at the lower end of the L-shaped slider 12, and a rebound component is installed inside the switch housing 1, and the rebound component is transmission-connected to the circular plate 16 and the switch button 11.
[0024] In the initial state, the switch cover 13 causes the L-shaped slider 15 to be located on the upper side of the sliding groove 14 under the resilience of the first spring 15, so that the switch cover 13 closes the switch housing 1, which plays a protective role when not in use to prevent incorrect operation or water ingress; when the switch button 11 needs to be operated, the switch cover 13 is driven to slide downward, so that the L-shaped slider 12 overcomes the resilience of the first spring 15 and moves downward to leak out of the switch button 11, and at the same time, when the switch cover 13 slides downward to the bottom of the sliding groove 14, it will abut against the inclined surface of the trapezoidal locking block 18, so that the L-shaped slider 12 pushes the trapezoidal locking block 18 to move downward, and then drives the return plate 16 to move downward to overcome the resilience of the second spring 17, so that the upper side of the trapezoidal locking block 18 abuts against the lower side of the L-shaped locking block 12 until the trapezoidal locking block 18 coincides with the locking hole 19, and then The second spring 17 drives the trapezoidal locking block 18 to move upward and enter the locking hole 19 to lock the L-shaped slider 12 under the rebound force of the second spring 17, so that the switch cover 13 can be fixed in the state of leaking the switch button 11. At this time, the operator can press the button switch 11 to perform the switch operation, and the switch button 11 will move upward when one side is pressed downward, and the other side will move upward. The switch button 11 on the side moving downward drives the rebound component to move, so that the circular plate 16 and the trapezoidal locking block 18 move downward, and then the trapezoidal locking block 18 exits the locking hole 19, so that the L-shaped slider 12 will move upward under the rebound force of the first spring 15 to return to the initial state. In this way, there is no need for the operator to manually operate the switch cover 13 to close the switch housing 1, thereby avoiding the operator's misoperation caused by forgetting to close the switch cover 13 after pressing the switch button 11.
[0025] The utility model can protect the switch button inside the switch housing through the switch cover when not in use, so as to prevent water from entering the interior thereof and also prevent the switch button from being operated accidentally. When in use, the switch button can be exposed for operation only by moving the switch cover downward, and after the switch button is operated, the switch housing automatically returns to its original state under the drive of the rebound component, so as to avoid the problem of forgetting to close the switch cover.
[0026] Embodiment 2: Further improvement is made on the basis of Embodiment 1, the rebound component includes two trapezoidal blocks 20, the two trapezoidal blocks 20 are symmetrically installed on the upper and lower sides of the circular plate 16, the switch housing 1 is provided with four through slots 21 connecting the mounting slots and the circular plate 20, a horizontal plate 22 is slidably connected inside the through slots 21, the horizontal plate 22 is provided with a first inclined surface on the upper and lower sides, a vertical plate 23 is fixedly connected to the lower side of the horizontal plate 22, a second inclined surface is provided on the side of the vertical plate 23 close to the trapezoidal block 20, and abutment bars 24 are fixedly installed on the upper and lower sides of the switch button 11.
[0027] In the initial state, the circular plate 16 and the trapezoidal block 20 have a tendency to move upward, so that the inclined surface of the trapezoidal block 20 abuts against the second inclined surface of the vertical plate 23, and pushes the second inclined surface of the vertical plate 23 and the cross plate 22 to extend toward the installation groove, so that the first inclined surface of the cross plate 22 can extend into the installation groove, one is located at the lower side of the abutment strip 24, and the other is located at the upper side of the abutment strip 24; in this way, when any side of the switch button 11 is pressed, the cross plate 22 will be driven to enter the through groove 21 under the action of the first inclined surface, and the trapezoidal block 20 will be pushed downward by the vertical plate 23 and the second inclined surface to overcome the resilience of the second spring 17 and move downward, so that the circular plate 16 can drive the trapezoidal locking block 18 to exit the lock hole 19, so that the L-shaped locking block 12 slides upward to restore the initial state;
[0028] Similarly, the upward movement of the other abutting strip 24 will also push the second inclined surface, thereby driving the trapezoidal locking block 18 to exit the locking hole 19 .
[0029] The L-shaped slider 12 is equipped with a buffer assembly, which includes a limit block 25 slidably connected to the L-shaped slider 12, a limit groove slidably connected to the limit block 25 is provided inside the L-shaped slider 12, a third spring 26 is installed between the limit groove and the limit block 25, the limit block 25 is provided with third inclined surfaces 27 on both sides along the sliding direction of the L-shaped slider 12, and a groove 28 matching the limit block 25 is provided inside the switch housing 1.
[0030] The rebound force of the first spring 15 is greater than the rebound force of the third spring 26, so that when the operator drives the switch cover 13 to move, when the L-shaped slider 12 overcomes the rebound force of the first spring 15 and moves downward, it is also necessary to drive the limit block 25 to move downward, so that the third inclined surface 27 of the limit block 25 abuts against the side ridges of the groove 28, and then push the third inclined surface 27 and the limit block 25 to extend into the limit groove, and then the L-shaped slider 12 slides downward again. When the L-shaped slider 12 encounters the groove 28 again during the downward sliding process, the limit block 25 will extend outward from the limit groove into the groove 28 under the rebound force of the third spring 26, and then the third inclined surface 27 continues to move downward. The limit block 25 will then abut against the side edges of the groove 28 to drive the limit block 25 to extend into the limit groove, and the cycle will cause the limit block 25 to enter and exit the groove 28. Similarly, when the L-shaped slider 12 moves upward under the rebound force of the first spring 15, since the rebound force of the first spring 16 is greater than the third spring 26, the limit block 25, the third spring 26 and the third inclined surface 27 cooperate with each other to repeatedly enter and exit the groove 28. In this way, there is time buffer during the upward sliding process of the L-shaped slider 12, and the trapezoidal locking block 18 will not be unlocked and will not immediately rebound to the initial state, thereby preventing the switch cover 13 from clamping the finger pressing the switch button 11.
[0031] A buffer sponge 29 is installed inside the groove 28. The buffer sponge 29 can not only improve the buffering effect of the limit block 25, but also prevent the limit block 25 and the groove 28 from producing a hard collision sound.
[0032] The abutment strip 24 is made of a hollow transparent material and is filled with fluorescent liquid. The fluorescent liquid can illuminate the hollow abutment strip 24 in the dark, and play a positioning role for the switch button 11. At the same time, the hollow abutment strip 24 on the pressed side is located under the horizontal plate 22, and the fluorescent liquid is shielded by the horizontal plate 22, so that it can be distinguished which side is the part that needs to be pressed, making the operation more convenient.
[0033] The switch cover 13 is made of transparent acrylic material, and a plurality of friction strips 30 are installed on the left and right sides of the switch housing 1. The friction strips 30 increase the friction between the switch cover 13 and the switch housing 1, thereby reducing the speed of the rebound force of the switch cover 13.
[0034] The above embodiments are merely illustrative of the principles and effects of the present invention, and are not intended to limit the present invention. Anyone familiar with the technology may modify or change the above embodiments without violating the spirit and scope of the present invention. Therefore, all equivalent modifications or changes made by those with ordinary knowledge in the relevant technical field without departing from the spirit and technical ideas disclosed in the present invention shall still be covered by the claims of the present invention.
