Abstract
Description
Technical Field
[0001] This utility model relates to the technical field of switches, and in particular to the technical field of self-locking switches. Background Technology
[0002] Press-type electronic components are devices that use mechanical pressing or touch to switch circuits on and off or input signals. They are widely used in consumer electronics, industrial control, medical equipment, and other fields. These include microswitches, mechanical buttons (tactile switches), membrane switches, capacitive touch buttons, etc. The problem with these switches is that they require pressing to activate, and maintaining the activated state requires continuous manual pressing, making them inconvenient and laborious to use. Summary of the Invention
[0003] The purpose of this invention is to solve the problems in the prior art by proposing a self-locking switch that can maintain the triggered state of the press-type electronic component when pressed, eliminating the need for manual pressing and making it more convenient to use.
[0004] To achieve the above objectives, this utility model proposes a self-locking switch, including an outer bracket and a push-button electronic component disposed within the outer bracket. The outer bracket is provided with a push-button, and the outer bracket or the push-button electronic component is provided with a handle for engaging with the pressing part of the push-button electronic component. The handle is movably disposed, and the outer bracket is provided with a latching member for engaging with the end of the handle to limit the position of the handle. When the handle engages with the latching member, the handle is in a state where the pressing part of the push-button electronic component is pressed down.
[0005] The outer bracket is also provided with an unlocking component that slides with it, the unlocking component being used to push open the buckle to separate the buckle from the end of the pressure handle.
[0006] Preferably, the unlocking component is provided with a reset elastic element for driving it to move away from the latch.
[0007] Preferably, the reset elastic element is an elastic sheet integrally formed with the unlocking element, and the elastic sheet cooperates with the outer wall of the press-type electronic component or the outer bracket.
[0008] Preferably, the reset elastic element is a reset spring provided on the unlocking element, and the other end of the reset spring cooperates with the outer wall of the press-type electronic component or the outer bracket.
[0009] Preferably, the fastener includes a limiting surface for engaging with the end of the pressure handle and a guide section disposed on the upper side of the limiting surface.
[0010] Preferably, the buckle is fixedly mounted on the unlocking member and moves synchronously with the unlocking member.
[0011] Preferably, the latching component and the unlocking component are separately provided, the latching component is fixedly connected to the outer bracket or the press-type electronic component, and the end of the unlocking component is provided with a top opening portion for cooperating with the latching component.
[0012] Preferably, the unlocking component is provided with a disconnector for cooperating with the pressure handle. The disconnector is elastic and has a relief portion for disengaging the disconnector from the push button.
[0013] When the push-button is pressed, it contacts the disconnector and causes the disconnector to elastically deform, thereby pressing down the handle. The handle then presses down and triggers the push-button electronic component. When unlocked by the unlocking member, the unlocking member pushes away the latch to separate the latch from the end of the handle. At the same time, the clearance part moves to the position corresponding to the push-button, causing the disconnector to disengage from the push-button. The disconnector loses the pressure of the push-button and automatically resets, and the handle also automatically resets.
[0014] Preferably, the unlocking component is equipped with a roller.
[0015] The beneficial effects of this self-locking switch are as follows: This invention can keep the push-button electronic component in the triggered state during use, eliminating the need for manual pressing of the component, making it more convenient to use. It features a mechanical structure, low cost, and easy installation and maintenance. It can be applied to the improvement of existing ordinary push-button electronic components. Unlocking is convenient; traditional self-locking switches typically lock upon first press and unlock upon second press, while this invention has a separate unlocking mechanism, making it more flexible and easier to operate.
[0016] The features and advantages of this utility model will be described in detail through embodiments and accompanying drawings. Attached Figure Description

Detailed Implementation
[0028] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. However, it should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit its scope. Furthermore, descriptions of well-known structures and technologies are omitted in the following description to avoid unnecessarily obscuring the concept of the present utility model.
[0029] In the description of this utility model, it should be noted that when an element is referred to as being "fixed to" or "set on" another element, it can be directly on or indirectly on the other element. When an element is referred to as being "connected to" another element, it can be directly connected to or indirectly connected to the other element.
[0030] In the description of this utility model, it should be noted that the terms "center," "length," "width," "thickness," "upper," "lower," "front," "rear," "left," "right," "vertical," "horizontal," "top," "bottom," "inner," and "outer," etc., indicating the orientation or positional relationship, are based on the orientation or positional relationship shown in the accompanying drawings, or the orientation or positional relationship commonly used when the utility model product is in use. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model. Furthermore, the terms "first," "second," and "third," etc., are only used to distinguish descriptions and should not be construed as indicating or implying relative importance. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this utility model, "multiple" means two or more, unless otherwise explicitly specified. "Several" means one or more, unless otherwise explicitly specified.
[0031] In the description of this utility model, it should also be noted that, unless otherwise explicitly specified and limited, the terms "set," "install," "connect," and "link" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances. Example 1:
[0032] See Figures 1-4This utility model discloses a self-locking switch, comprising an outer bracket 1, a push-button electronic component 2 disposed within the outer bracket 1, a push-button 3 disposed on the outer bracket 1, and a handle 4 disposed on the push-button electronic component 2 and used to cooperate with the pressing part of the push-button electronic component 2. In this embodiment, one end of the handle 4 is hinged to the push-button electronic component 2, and it can rotate around the hinge position. The handle 4 is driven to spring back to its original position by the elastic force of the button on the push-button electronic component 2 or by an additional elastic element. The push-button 3 is fixed on the outer bracket 1. When the push-button 3 is pressed, the push-button 3 can extend into the outer bracket 1. The outer bracket 1 contains a pressing handle 4, and a latching member 5 is provided inside the outer bracket 1 to engage with the end of the pressing handle 4. When the pressing handle 4 is engaged with the latching member 5, the pressing handle 4 is in a state where the pressing part of the pressing electronic component 2 is pressed down. The outer bracket 1 also has an unlocking member 6 that slides with it. The unlocking member 6 is used to push open the latching member 5 to separate the latching member 5 from the end of the pressing handle 4. The unlocking member 6 has a reset elastic member for driving it to move away from the latching member. In this embodiment, the pressing electronic component 2 is a micro switch, and the trigger part of the micro switch is set towards the pressing handle 4. When this embodiment is working, refer to Figure 3 When the push-button 3 is pressed, it extends into the outer bracket 1 and presses the handle 4. The handle 4 deforms elastically, triggering the push-button electronic component 2, i.e., the microswitch. The end of the handle 4 falls into the latch 5 and is locked in place, preventing the handle 4 from popping up and maintaining the state of triggering the push-button electronic component 2. When unlocking is required, refer to [the relevant documentation]. Figure 4 Pressing the unlocking component 6 causes the latching component 5 to move away from the handle 4, separating the end of the handle 4 from the latching component 5. The handle 4 then automatically springs back up, releasing the press-type electronic component 2 and unlocking it. This embodiment allows the press-type electronic component 2 to remain in the triggered state during use without requiring continuous manual pressing, making it more convenient to use. Its mechanical structure is low-cost and easy to install and maintain. It can be applied to the improvement of existing ordinary press-type electronic components 2, facilitating easy unlocking. In another optional embodiment, one end of the handle 4 can also be fixedly connected to the press-type electronic component 2 or the outer bracket 1, and the handle 4 can be configured with a self-elastic structure, automatically resetting based on its own elasticity.
[0033] See Figure 2 , Figure 3 In this embodiment, the reset elastic element is an elastic sheet 61 integrally formed with the unlocking element 6, and the elastic sheet 61 abuts against the outer wall of the press-type electronic component 2. The integrally formed elastic sheet 61 is easier to manufacture, has stable performance, and is easy to install.
[0034] Preferably, in this embodiment, the latching component 5 is integrally formed on the unlocking component 6 and moves synchronously with the unlocking component 6. This makes production more convenient, provides stable performance, facilitates installation, and ensures strong synchronization.
[0035] See Figure 2 , Figure 3 The latching member 5 includes a limiting surface 51 for engaging with the end of the pressure handle 4 and a guide section 52 disposed on the upper side of the limiting surface 51. The limiting surface 51 is used to engage with the pressure handle 4 and limit the pressure handle 4, while the guide section 52 is used to abut against the end of the pressure handle 4 and guide its end into the limiting surface 51 when the pressure handle 4 is pressed down. Example 2:
[0036] See Figures 5-8 Based on Embodiment 1, the difference between this embodiment and Embodiment 1 is that: the latching component 5 and the unlocking component 6 are separately configured; the latching component 5 is fixedly connected to the press-type electronic component 2; and the end of the unlocking component 6 is provided with a top opening portion 63 for cooperating with the unlocking component 6. This embodiment provides another way for the latching component 5 and the unlocking component 6 to cooperate, that is, the two are separately configured. When the unlocking component 6 moves towards the latching component 5, the top opening portion 63 contacts the latching component 5, thereby causing the latching component 5 to elastically deform. The top opening portion 63 pushes the latching component 5 open until the pressure handle 4 separates from the end of the latching component 5. In this embodiment, the latching component 5 and the unlocking component 6 are separately configured, and a gap is left between them as a play to prevent impact during use, causing the unlocking component 6 to move under inertia; or the manufacturing or installation accuracy of the parts on the tool used to cooperate with the unlocking component 6 to drive the unlocking component is poor, causing the unlocking component 6 to move and accidentally push open the latch.
[0037] See Figure 5 The unlocking component 6 is provided with a disconnector 7 that cooperates with the pressure handle 4. The disconnector 7 is elastic and has a relief portion for disengaging the disconnector 7 from the push button 3.
[0038] See Figure 8 When the push-button 3 is pressed, it contacts the disconnector 7, causing the disconnector 7 to elastically deform, thereby pressing down the handle 4 through the disconnector 7. The handle 4 then presses down and triggers the push-button electronic component 2. At this time, the avoidance part 71 and the push-button 3 are in a misaligned position. See also Figure 9When the unlocking member 6 is pressed, the unlocking member 6 pushes open the latching member 5 to separate the latching member 5 from the end of the pressure handle 4. At the same time, the avoidance part 71 moves to the position corresponding to the press button 3, so that the disconnector 7 is disengaged from the press button 3. The disconnector 7 loses the pressure of the press button 3 and automatically resets. At the same time, the pressure handle 4 also automatically resets. In this embodiment, by setting the disconnector 7 to cooperate with the pressure handle 4, when unlocking, when the unlocking member 6 pushes open the buckle 5, the avoidance part 71 can move to the corresponding position of the press button 3. The press button 3 can fall into the avoidance part 71, the disconnector 7 loses the pressure of the press button 3, the disconnector 7 automatically resets and pops up, and at the same time the pressure handle 4 also automatically pops up, and the press electronic component 2 is deactivated. In this embodiment, by setting the disconnector 7, unlocking can be convenient, ensuring that when the unlocking member 6 unlocks, the trigger part of the press electronic component 2 can definitely pop up, and unlocking can be performed even if the press button 3 is kept in the pressed state.
[0039] See Figure 5 The difference between this embodiment and Embodiment 1 is that the reset elastic element is a reset spring 62 disposed on the unlocking element 6, and the other end of the reset spring 62 cooperates with the outer bracket 1. This embodiment provides another reset elastic element solution, directly using a finished spring as the reset elastic element, which is convenient for production.
[0040] See Figure 5 The unlocking component 6 is also equipped with a roller 8. The roller 8 can cooperate with other rotating components, such as... Figure 9 , Figure 10 As shown, a rotatable disc is set next to the roller 8, and a protruding part is set on the disc. When the disc is rotated, the protruding part on the disc can cooperate with the roller 8 to unlock. When the protruding part rotates to the roller 8, the protrusion can make the unlocking part 6 move towards the buckle part 5, thereby unlocking. The disc can be connected to components such as a motor to realize electric unlocking.
[0041] The working process of this utility model:
[0042] In operation, this utility model discloses a self-locking switch. When the push-button 3 is pressed, it extends into the outer bracket 1 and presses the handle 4. The handle 4 elastically deforms, thereby triggering the push-button electronic component 2, i.e., the micro switch. The end of the handle 4 falls into the latch 5 and is locked by the latch 5, thus preventing the handle 4 from popping up and maintaining the state of triggering the push-button electronic component 2. When unlocking is required, the unlocking component 6 is pressed. The unlocking component 6 pushes the latch 5 to separate the latch 5 from the end of the handle 4, and the handle 4 automatically pops up, thereby releasing the push-button electronic component 2 and realizing unlocking.
[0043] All standard parts used in this application can be purchased from the market. The specific connection methods of each part adopt conventional methods such as bolts, rivets, and welding that are mature in the existing technology. The internal components of the electric slide rail, cylinder, welding machine, electric telescopic rod and controller all adopt conventional models in the existing technology, and their internal structure belongs to the existing technology structure. Workers can complete the normal operation of them according to the existing technical manual.
