Abstract
Description
Technical Field
[0001] The utility model relates to a button, in particular to an ultra-short self-locking button. Background Technique
[0002] A push-button switch refers to a switch that uses a button to push a transmission mechanism to make the moving contact and the static contact connect or disconnect to realize circuit switching. The push-button switch is a main control electrical appliance with a simple structure and wide application. In an electrical automatic control circuit, it is used to manually send a control signal to control contactors, relays, electromagnetic starters, etc. The ultra-short self-locking type is a self-locking switch, and basically all on the market are self-restoring types without self-locking function.
[0003] In addition, when the push-button switch is in use, since there are moving parts in the structure, that is, the button key, even if a waterproof sheet and other structures are provided in the structure, due to the existence of gaps in the structure, the possibility of water seepage is relatively large. Long-term water seepage is likely to cause poor contact and tripping and burning. Moreover, during use, once abnormal operation occurs and the switch is turned on, the user's finger directly touches it, there is a risk of electric shock. When the push-button switch is abnormal and is directly turned on, it will bring greater potential safety hazards. Content of the Utility Model
[0004] The purpose of the utility model is to provide an ultra-short self-locking button to solve the problems raised in the above background technique.
[0005] To achieve the above purpose, the utility model provides the following technical scheme: an ultra-short self-locking button, including a housing, the top of the inner wall of the housing is fixedly connected with a sliding seat, the inner wall of the sliding seat is vertically slidably connected with a lid, a waterproof sheet is arranged at the bottom end of the sliding seat, a waterproof rubber ring is fixedly connected to the center of the waterproof sheet, a tension film is fixedly connected to the center of the waterproof rubber ring, a middle seat is arranged at the bottom end of the waterproof sheet, and an integrated circuit board is installed at the bottom end of the middle seat;
[0006] A circular groove is opened at the center of the lid, a metal plate is fixedly connected to the top of the inner wall of the circular groove, a high-resistance resistor is fixedly connected to the bottom end of the metal plate, and a conductive column is fixedly connected to the bottom end of the high-resistance resistor.
[0007] As a preferred technical scheme of the utility model, a push rod is fixedly connected to the middle of the bottom end of the lid, a through groove is opened in the middle of the sliding seat, and the push rod penetrates through the through groove.
[0008] As a preferred technical scheme of the utility model, the middle seat is fixedly arranged in the middle of the inner wall of the housing.

[0010] As a preferred technical solution of the present utility model, the bottom end of the conductive column is connected to the push rod.
[0011] As a preferred technical solution of the present utility model, the lid is made of insulating plastic, and the metal plate is made of conductive metal material.
[0012] Compared with the prior art, the beneficial effects of the present utility model are as follows:
[0013] 1. By setting an integrated circuit board in the present utility model, it can be controlled by a chip, with a self-locking function, integrated circuit. Compared with ordinary micro-travel switches, the output current is larger, the functions are more comprehensive, and the application fields are wider. By installing a waterproof sheet inside, moisture can be isolated. Cooperating with the tension film connected by a waterproof rubber ring, since it has better flexibility relative to the waterproof sheet, it can avoid deformation and cracking at the pressing place caused by long-term active pressing, ensuring long-term waterproof effect. The provided expansion ring can expand when encountering water and tightly press against the gaps entering the integrated circuit board to prevent moisture from seeping in, with stronger waterproof effect.
[0014] 2. By setting the metal plate at the center of the lid in the present utility model, when pressing with a finger, it is certain to touch the metal plate. In this way, when dangerous situations such as poor contact or electric leakage occur inside the button, the high-resistance resistor at the bottom of the metal plate can divide the voltage of the generated electric leakage, so that the current flowing into the human body is a safe current. Therefore, even when the button works abnormally, the safety of the opening personnel is guaranteed. BRIEF DESCRIPTION OF THE DRAWINGS

[0021] 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. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.
[0022] Please refer to Figures 1-5 , the present invention provides a technical solution for an ultra-short self-locking button:
[0023] Embodiment 1:
[0024] According to Figure 1 、 Figure 2 As shown, an ultra-short self-locking button includes a housing 1. A sliding seat 3 is fixedly connected to the top of the inner wall of the housing 1. A lid 2 is vertically slidably connected to the inner wall of the sliding seat 3. A waterproof sheet 4 is provided at the bottom end of the sliding seat 3. A waterproof rubber ring 9 is fixedly connected to the center of the waterproof sheet 4. The waterproof rubber ring 9 tightly connects the tension film 10 and the waterproof sheet 4 to form an integral body. Therefore, a good waterproof effect still exists. However, compared with the waterproof sheet 4, the tension film 10 has better flexibility and can avoid deformation and cracking caused by multiple deformations during multiple pressing and bouncing processes, thus ensuring integrity and service life. A tension film 10 is fixedly connected to the center of the waterproof rubber ring 9. A middle seat 5 is provided at the bottom end of the waterproof sheet 4. An integrated circuit board 6 is installed at the bottom end of the middle seat 5;
[0025] A push rod is fixedly connected to the middle of the bottom end of the lid 2. A through groove is formed in the middle of the sliding seat 3. The push rod passes through the through groove. The middle seat 5 is fixedly arranged in the middle of the inner wall of the housing 1. A plurality of pins 7 are installed at the bottom end of the integrated circuit board 6. A base 8 is snap-connected to the bottom of the inner wall of the housing 1. The plurality of pins 7 pass through the base 8.
[0026] During specific use, the utility model is an ultra-short self-locking button. The operator can combine multiple structural parts together. During normal use of the button, the finger first presses the cover 2 on the shell 1, so that the cover 2 slides down vertically along the sliding seat 3, so that the push rod at the bottom thereof will pass through the through groove, and with the help of the resisting tension membrane 10, press the button body on the integrated circuit board 6. The integrated circuit board 6 has a self-locking function and is chip-controlled. During long-term pressing and use, if moisture enters through the gap of the cover 2, the moisture will be blocked by the waterproof sheet 4, and the moisture will gradually spread to the expansion ring 11. The expansion ring 11 made of water-swelling rubber will expand and fully press against the inner wall of the shell 1 to prevent moisture from spreading downward toward the integrated circuit board 6, thereby achieving a good waterproof effect. At the same time, under long-term pressing, the tension membrane 10 has good elasticity and is not easy to deform itself under pressing. At the same time, it is tightly connected to the waterproof sheet 4 with the help of the waterproof rubber ring 9, thereby achieving an overall waterproof effect.
[0027] Embodiment 2:
[0028] On the basis of the first embodiment, Figure 1 and Figure 3 , Figure 5 As shown, a circular groove is opened at the center of the cover 2, a metal plate 12 is fixedly connected to the top of the inner wall of the circular groove, a high-resistance resistor 13 is fixedly connected to the bottom end of the metal plate 12, a conductive column 14 is fixedly connected to the bottom end of the high-resistance resistor 13, and the bottom end of the conductive column 14 is connected to the push rod. The cover 2 is made of insulating plastic, and the metal plate 12 is made of conductive metal.
[0029] During specific use, the utility model provides an ultra-short self-locking button. When the self-locking button has dangerous conditions such as poor contact or leakage, when the operator presses it to open, the finger will inevitably touch the metal plate 12 on the cover 2 when pressing the button to open. In this way, the high-resistance resistor 13 at the bottom of the metal plate 12 will divide the possible leakage through the high-resistance resistor 13 and then flow into the human body as a safe current. In this way, even if the button is abnormal, the safety of the person opening the button is guaranteed.
