Description

Technical Field

[0001] The utility model relates to the technical field of control buttons, in particular to a magnetic absorption reset button. Background Art

[0002] The reset of traditional control buttons is mostly of the spring reset type. Although adding a spring facilitates the reset of the button, inevitably, after frequent pressing and use, the spring is prone to fatigue damage, resulting in the inconvenience of button reset. In order to avoid such problems, a magnetic absorption reset button is proposed to solve the existing problems. Summary of the Invention

[0003] Aiming at the deficiencies of the prior art, the utility model provides a magnetic absorption reset button, which solves the problem that the traditional spring-type control button loses its reset ability due to spring fatigue.

[0004] To achieve the above object, the utility model is realized through the following technical solutions: A magnetic absorption reset button includes a plastic assembly housing and an upper cover iron sheet. The upper cover iron sheet is arranged at the top of the plastic assembly housing. On both sides of the bottom of the inner cavity of the plastic assembly housing, a first metal pin and a second metal pin are respectively installed. A plastic support plate is movably arranged inside the plastic assembly housing. A plurality of soft plastic spacer blocks are fixedly arranged around and equidistantly on the top of the plastic support plate. A magnet used in cooperation with the upper cover iron sheet is installed on the top of the plastic support plate and between a plurality of the soft plastic spacer blocks. The tops of the plurality of soft plastic spacer blocks are fixedly connected together with a key cap.

[0005] Preferably, slots are opened on both sides of the upper cover iron sheet, and clamping plates used in cooperation with the slots are fixedly connected to both sides of the plastic assembly housing.

[0006] Preferably, a limit sliding groove slidably adapted to the key cap is opened on the top of the upper cover iron sheet.

[0007] Preferably, a pressing head used in cooperation with the second metal pin is fixedly connected to the bottom of the plastic support plate. Advantageous Effects

[0008] The utility model provides a magnetic absorption reset button. Compared with the existing technology, it has the following advantageous effects: By arranging a magnet between the plastic support plate and the key cap, and arranging an upper cover iron sheet used in cooperation with the magnet at the top of the plastic assembly housing, the elastic reset of the key cap can be easily completed through the adsorption cooperation between the magnet and the upper cover iron sheet, avoiding the problem that the traditional spring is prone to fatigue damage and the key cap loses its reset ability;

[0009] Secondly, a soft plastic spacer block is arranged on the top of the plastic pallet, so that when the magnet adsorbs the iron sheet of the upper cover, the adsorption space between the magnet and the iron sheet of the upper cover can be increased through the soft plastic spacer block, facilitating the labor-saving detachment cooperation between the iron sheet of the upper cover and the magnet. Moreover, by making the magnet contact the iron sheet of the upper cover at a small interval, the sound generated during reset can also be weakened.

[0010] Secondly, a pressing head is arranged at the bottom of the plastic pallet, so that the second metal pin is easy to be stressed and contact the first metal pin stably and well. Description of the Drawings

[0018] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model.

[0019] Please refer to Figures 1-6 , the present utility model provides a technical solution: a magnetic reset button, including a plastic assembly housing 1 and an iron sheet 2 of the upper cover. The iron sheet 2 of the upper cover is arranged on the top of the plastic assembly housing 1. On both sides of the bottom of the inner cavity of the plastic assembly housing 1, a first metal pin 3 and a second metal pin 4 are respectively installed. Card slots 10 are opened on both sides of the iron sheet 2 of the upper cover, and card boards 11 matching the card slots 10 are fixedly connected to both sides of the plastic assembly housing 1. As a detailed explanation: both the first metal pin 3 and the second metal pin 4 are made of copper.

[0020] Furthermore, for the convenience of the relatively silent reset of the keycap 8, a plastic support plate 5 is movably arranged inside the plastic assembly housing 1. A number of soft plastic spacer blocks 6 are fixedly arranged at equal intervals around the top of the plastic support plate 5. A magnet 7 that is used in cooperation with the upper cover iron sheet 2 is installed between a number of the soft plastic spacer blocks 6 on the top of the plastic support plate 5. The tops of a number of the soft plastic spacer blocks 6 are fixedly connected together with the keycap 8. A limiting sliding groove 12 that is slidably adapted to the keycap 8 is opened at the top of the upper cover iron sheet 2. A pressing head 9 that is used in cooperation with the second metal pin 4 is fixedly connected to the bottom of the plastic support plate 5.

[0021] During use, when a finger presses down the keycap 8, it causes the keycap 8 to drive the magnet 7, the soft plastic spacer blocks 6, and the plastic support plate 5 to descend. The plastic support plate 5 drives the pressing head 9 to press down the contact elastic piece in the middle of the second metal pin 4, causing the elastic piece of the second metal pin 4 to contact the first metal pin 3 to form a circuit. After releasing the keycap 8, the magnet 7, through the magnetic adsorption with the upper cover iron sheet 2, causes the magnet 7 to drive the plastic support plate 5, the soft plastic spacer blocks 6, the keycap 8, and the pressing head 9 to rise. The pressing head 9 rises to disengage from the pressing and cooperation with the elastic piece of the second metal pin 4. When the soft plastic spacer blocks 6 rise, an adsorption interval will be formed between the upper cover iron sheet 2 and the magnet 7.
