Throughout the entire operation, it is not necessary to release the pressing cover, which facilitates immediate shutdown of the switch body in case of an accident, making it relatively safe and reliable.

Description

Technical Field

[0001] This invention belongs to the field of push-button switch technology, specifically, it relates to a hand-operated or foot-operated switch. Background Technology

[0002] A hand-operated or foot-operated switch is a composite switch device that combines manual triggering and foot operation. It is typically suitable for scenarios that require hands-free and foot-operated operation, especially in industrial production, medical equipment, and entertainment facilities. It balances safety and convenience, effectively improving work efficiency and reducing human error.

[0003] The hand-operated foot switch mainly consists of a housing and a switch body installed inside the housing. The switch body is connected to the equipment. After pressing the button on the housing, the switch body can be turned on or off, thereby achieving the purpose of controlling the equipment to turn on or off. In order to facilitate the control of the equipment in a certain state, the switch body is mostly equipped with a self-locking setting. That is, after the button is pressed for the first time, the switch body will be locked in the open state. Only after releasing the button and pressing the button again will the switch body be turned off.

[0004] In actual use, when the switch body is turned on after the button is pressed, if the controlled equipment malfunctions, the operator still needs to release the button and press it again to turn off the switch body, which can easily lead to safety accidents. At the same time, the operator may also be nervous due to the equipment malfunction and reflexively press the button, further prolonging the time it takes for the switch body to turn off. Summary of the Invention

[0005] Existing hand-operated or foot-operated switches employ a self-locking mechanism. Once activated, if the controlled equipment malfunctions, the operator needs to press the button twice to close the switch. Furthermore, operator nervousness can easily cause the button to be pressed incorrectly, resulting in a slow and inefficient closing mechanism. To address this issue, the following invention is proposed:

[0006] A hand-operated foot switch includes a housing and a switch body disposed within the housing. The housing includes a top cover and a base. A mounting base is provided on the top cover, and a press cover is elastically connected to the mounting base. A button is provided on the top of the press cover. A press head that can be elastically pressed is provided on the upper part of the switch body. A first push block is vertically elastically connected to the mounting base, and a second push block is vertically elastically connected to the press cover. A first baffle and a second baffle are horizontally elastically connected. The bottom of the second push block is higher than the bottom of the first push block. The first baffle abuts against the top of the first push block, and the second baffle abuts against the top of the second push block. A first drive block and a second drive block extending vertically upward are also provided on the mounting base.

[0007] After pressing the button, the pressing cover moves downward, the first baffle drives the first push block to move downward and press the pressing head down. At the same time, the first drive block pushes the first baffle to move and releases the resistance to the first push block. The first push block is driven upward by the elastic force. Then the pressing head resets and the switch body enters the open state. Pressing the button again moves the pressing cover downward, the second baffle drives the second push block to move downward and press the pressing head down a second time. At the same time, the second drive block pushes the second baffle to move and releases the resistance to the second push block. Then the pressing head resets upward and the switch body enters the closed state.

[0008] Furthermore, the press cover is also provided with a boss, and the boss is provided with a protrusion. The first baffle is rotatably mounted on the boss. A first return spring is provided between the protrusion and one side of the first baffle, which are laterally elastically connected. A second return spring is provided between the second baffle and the side wall of the press cover, which are laterally elastically connected. After the button is released, the button cover moves upward, and at the same time, the first return spring and the second return spring drive the first baffle and the second baffle to reset.

[0009] Furthermore, the first baffle is provided with a first guide hole, and the first guide hole is provided with an oblique first guide surface. The first drive block is provided with an oblique first drive surface that matches the first guide surface. After the first baffle moves down with the pressing cover, the first drive surface abuts against the first guide surface, so that the first baffle rotates horizontally until it no longer abuts the first push block, and the first push block can then move upward.

[0010] Furthermore, the second baffle is provided with an oblique second guide hole, and a second guide surface is provided inside the second guide hole. The second drive block is provided with an oblique second drive surface that matches the second guide surface. After the second baffle moves down with the pressing cover, the second drive surface abuts against the first guide surface, so that the second baffle moves horizontally until it no longer abuts the second push block. The second push block can then move upward under the push of the pressing head.

[0011] Furthermore, a first reset spring is provided between the press cover and the mounting base to elastically connect the two, and horizontally extending reset arms are provided on both sides of the first push block. A second reset spring is provided between the reset arms and the mounting base to elastically connect the two, and a third reset spring is provided between the second push block and the press cover to elastically connect the two. The first reset spring, the second reset spring, and the third reset spring are respectively responsible for providing the spring force required for the reset of the button cover, the first push block, and the second push block when there is no pressing.

[0012] Furthermore, the first baffle is fan-shaped, the first guide hole is fan-ring shaped, the first drive block is fan-ring shaped to match the first guide hole, and the first push block and the second push block can pass vertically through the first guide hole and the second guide hole respectively, after which the first baffle and the second baffle are limited.

[0013] Furthermore, the pressing cover is also provided with an outer limiting platform, the first push block is movably disposed in the outer limiting platform, and the outer limiting platform is provided with a first limiting plate that abuts against one side of the first baffle.

[0014] Furthermore, an inner limiting platform is provided on the inner side of the outer limiting platform, the second push block is elastically disposed in the inner limiting platform, the side of the inner limiting platform is provided with an insertion hole located above the first push block, the end of the second baffle is inserted into the insertion hole and abuts against the top of the first push block, and a second limiting plate located outside the insertion hole is also provided on the second baffle.

[0015] This invention proposes a hand-operated foot switch. During the pressing process, the pressing head of the switch body is pressed downwards and transitions from the closed state to the open state, then locks itself. Afterwards, the operator can choose to release the button or continue pressing it. After continuing to press the button, the pressing head of the switch body is pressed downwards a second time and transitions from the open state to the closed state. The advantage is that when the switch body is in the open state, if the operator discovers an abnormality, they can directly close the switch body by continuing to press the button without having to release the button and press it a second time, thus improving the closing speed of the switch body and making it safer and more reliable.

[0024] The technical solution of the present invention will be clearly and completely described below with reference to the embodiments.

[0025] Based on the embodiments in this application, all other embodiments obtained by those skilled in the art without creative effort should fall within the scope of protection of this application.

[0026] It should be noted that the terms "first," "second," etc., in the specification, claims, and accompanying drawings of this application are used to distinguish similar objects and are not necessarily used to describe a specific order or sequence. It should be understood that such use of data can be interchanged where appropriate for the embodiments of this application described herein.

[0027] Furthermore, the terms “comprising” and “having”, and any variations thereof, are intended to cover non-exclusive inclusion, such that a process, method, system, product, or apparatus that includes a series of steps or units is not necessarily limited to those steps or units that are explicitly listed, but may include other steps or units that are not explicitly listed or that are inherent to such process, method, product, or apparatus.

[0028] In this application, the terms "upper," "lower," "left," "right," "front," "rear," "top," "bottom," "inner," "outer," "middle," "vertical," "horizontal," "lateral," and "longitudinal" indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. These terms are primarily for the purpose of better describing the invention and its embodiments, and are not intended to limit the indicated device, element, or component to having a specific orientation, or to be constructed and operated in a specific orientation.

[0029] like Figures 1-6As shown, this is a preferred embodiment of the present invention, a hand-operated foot switch, including a housing 1, a switch body 2, a pressing cover 4, and a button 13. The housing 1 includes an upper cover 12 and a base 11 fixedly installed below the upper cover 12. The switch body 2 is fixedly disposed between the upper cover 12 and the base 11. The upper cover 12 is provided with a mounting base 3, and the pressing cover 4 is elastically connected to the mounting base 3. The button 13 is fixedly provided on the top of the pressing cover 4. The upper part of the switch body 2 is provided with a pressing head 21 that can be elastically pressed downward, and the pressing head 21 is located at the center of the mounting base 3.

[0030] A first push block 5 is vertically elastically connected to the mounting base 3. The bottom of the first push block 5 vertically passes through the mounting base 3 and is located above the pressing head 21. A second push block 6 is vertically elastically connected inside the pressing cover 4. A first baffle 43 and a second baffle 46 are horizontally elastically connected. The first push block 5 is sleeved on the outside of the second push block 6, and the bottom of the second push block 6 is higher than the bottom of the first push block 5. The first baffle 43 abuts against the top of the first push block 5, and the second baffle 46 abuts against the top of the second push block 6. A first drive block 34 and a second drive block 36 are also provided on the mounting base 3, extending vertically upward. The first baffle 43 and the second baffle 46 are located directly above the first drive block 34 and the second drive block 36, respectively.

[0031] After button 13 is pressed, button 13 moves the pressing cover 4 downward. The first baffle 43 and the second baffle 46 move downward together with the button 13 cover. The first baffle 43 will abut against and drive the first push block 5 to move downward. After the first push block 5 moves downward, it presses the pressing head 21. During this process, the first drive block 34 will push the first baffle 43 to move until it releases the abutment against the first push block 5. After the first push block 5 loses the abutment, it will be driven by elastic force to move upward relative to the second push block 6, and then will no longer move downward together with the pressing cover 4. After that, the pressing head... When the first push block 5 is released, the button 21 will spring back upward and move closer to the second push block 6, at which point the switch body 2 enters the open state. Pressing button 13 further moves the pressing cover 4 downward, causing the second baffle 46 to abut against and drive the second push block 6 downward. The second push block 6 then presses the pressing head 21 a second time. During this process, the second drive block 36 pushes the second baffle 46 until it releases its contact with the second push block 6. After the second push block 6 loses its contact, the pressing head 21 returns to its upward position, and the switch body 2 enters the closed state. In other words, a single press by the operator can switch the switch body 2 from closed to open with self-locking, and then from open with self-locking back to closed. When the switch body 2 enters the open self-locking state or enters the closed state for the second time, the operator can release button 13. Then, the button 13 cover moves upward and returns to its original position, while the switch body 2 maintains its current state.

[0032] like Figures 3-6As shown, further, a boss 49 is provided inside the pressing cover 4, and a protrusion 50 is provided on the boss 49. The first baffle 43 is fan-shaped and is rotatably mounted on the boss 49. A first return spring 41 is provided between the protrusion 50 and one side of the first baffle 43, which is also fan-shaped. A second return spring 42 is provided between the second baffle 46 and the side wall of the pressing cover 4, which is also fan-shaped.

[0033] The structure of the first baffle 43 and the second baffle 46 is further described in detail below, such as Figure 3 and Figure 5 As shown, the first baffle 43 is provided with a fan-shaped first guide hole 44, and the first guide hole 44 is provided with an oblique first guide surface 45. The first drive block 34 is fan-shaped and matches the first guide hole 44. The first drive block 34 is provided with an oblique first drive surface 35 that matches the first guide surface 45. After the first baffle 43 moves down with the pressing cover 4, the first drive surface 35 abuts against the first guide surface 45. The first baffle 43 rotates horizontally due to the force on the first drive surface 35 until it no longer abuts the first push block 5. Then the first push block 5 moves upward and the first drive block 34 passes vertically through the first guide hole 44.

[0034] Furthermore, the second baffle 46 is provided with an oblique second guide hole 47, and a second guide surface 48 is provided inside the second guide hole 47. The second drive block 36 is provided with an oblique first drive surface 35 that matches the second guide surface 48. After the second baffle 46 moves down with the pressing cover 4, the second drive surface 37 abuts against the first guide surface 45. The second baffle 46 rotates horizontally due to the force on the second drive surface 37 until it no longer abuts against the second push block 6. Then the second push block 6 can be pressed up by the pressing head 21 and moved upward. The second push block 6 passes vertically through the second guide hole 47.

[0035] Furthermore, such as Figure 5 As shown, a first reset spring 31 is provided between the pressing cover 4 and the mounting base 3 to elastically connect the two. The first push block 5 has horizontally extending reset arms 51 on both sides. A second reset spring 32 is provided between the reset arms 51 and the mounting base 3 to elastically connect the two. A third reset spring 33 is provided between the second push block 6 and the pressing cover 4, with its end fixedly connected to both, thereby elastically connecting the two. The elastic force provided by the third reset spring 33 is weaker than the elastic force received by the pressing head 21 when it resets. That is, after the second push block 6 loses the pressure of the second baffle 46, it cannot prevent the pressing head 21 from resetting upward.

[0036] Furthermore, such as Figures 5-6As shown, the pressing cover 4 is also provided with an outer limiting platform 14 and an inner limiting platform 15 located inside the outer limiting platform 14. The first push block 5 is movably disposed inside the outer limiting platform 14. The outer limiting platform 14 is provided with a first limiting plate 52 that abuts against the other side of the first baffle 43, so as to limit the rotation of the first limiting plate 52 within a certain angle. When the first baffle 43 no longer abuts against the first push block 5, it will be passed through by the first push block 5 and limited. After the pressing cover 4 moves upward, the first baffle 43 is driven by the elastic force to restart. The rotation continues until it is blocked by the first limiting plate 52; the second push block 6 is elastically disposed in the inner limiting platform 15, and the inner limiting platform 15 has insertion holes 16 on both sides located above the first push block 5. The end of the second baffle 46 is inserted into the insertion hole 16 and abuts against the top of the first push block 5. After being driven by the second baffle 46, the second baffle 46 moves horizontally to the outside of the insertion hole 16. A second limiting plate 61 located outside the insertion hole 16 is also provided on the second baffle 46 to prevent the second baffle 46 from going too deep into the insertion hole 16.

[0037] The above description is merely a specific embodiment of the present application, but the scope of protection of the present application is not limited thereto. Any changes or substitutions that can be easily conceived by a person skilled in the art within the technical scope disclosed in this application should be included in the scope of protection of this application. Therefore, the scope of protection of this application should be based on the scope of protection of the claims.
