Description

Technical Field

[0001] The invention belongs to the field of emergency stop devices, and more specifically, relates to an emergency stop button with mechanical indication. Background Art

[0002] The emergency stop button is also called the emergency stop button. It is a protective measure that people can quickly press when an emergency occurs. Existing products generally do not have the function of displaying the emergency stop status. Some existing products use indicator lights to display the emergency stop status, such as adding an indicator light on the outside, or directly adding a light on the emergency stop button.

[0003] However, further research shows that the above-mentioned prior art still has the following defects or shortcomings: for some special industry cabinets, due to the limitations of usage conditions, there is only one emergency stop button on its surface and other indicator lights cannot be set; when the operator powers on, due to failure to promptly discover that the emergency stop button has been pressed, the equipment may be powered on or off instantly, and a short-term current shock may be generated, which may have an adverse effect on the equipment; in addition, even for occasions where a status indicator light can be added to the cabinet door, since it requires 220V or 24V power, it also brings a risk of electric shock to a certain extent.

[0004] Accordingly, the art urgently needs to make further research and improvement in this regard, so as to better solve the status display requirements of the emergency stop button. Summary of the invention

[0005] In response to one or more of the above defects or needs in the prior art, the present invention provides an emergency stop button with mechanical indication, wherein by studying and improving the specific structural composition and setting method of the emergency stop cover, the status display of the emergency stop button can be realized in a safe, reliable and easy-to-control mechanical manner without using any indicator light.

[0036] Figure 1 It is a schematic diagram of the main components of the emergency stop cover provided in the preferred embodiment of the present application. Figure 2a and 2b They are the structural cross-sectional views of the entire emergency stop button provided by the present application, and the emergency stop cover in the two figures is in the state of executing the emergency stop or releasing the emergency stop. Figure 1 and Figure 2a , 2b To explain the present invention in more detail.

[0037] The emergency stop button of the present invention includes an emergency stop cover, an emergency stop seat and an emergency stop action trigger mechanism. Figure 2a and 2b As specifically shown in the figure, the emergency stop button mainly includes an emergency stop cover 1, an emergency stop seat 2 and an emergency stop core 3 as an emergency stop action triggering mechanism, and also includes a locking element 4 for locking the emergency stop cover in different working states. Since the present invention focuses on making targeted improvements and redesigns on the key component, namely, the emergency stop cover, it is mainly explained below, and other components can adopt various well-known structural forms and functional designs in the art.

[0038] See also Figure 1 The emergency stop cover 1 mainly includes a boss 11, a left window 12, a right window 13, a first slide, a second slide and a transparent observation port 14. The present invention improves the specific structure and setting method of these components in order to realize an emergency stop button with a mechanical indication function.

[0039] Specifically, the boss 11 is arranged between the first ends of the left window 12 and the right window 13 and is pressed against them respectively, and the second end tail of the left window 12 and the right window 13 is respectively connected with a torsion spring (not clearly shown in the figure); the first slide is arranged along the vertical direction to provide a track for the boss to perform up and down movement; the second slide is arranged along the circumferential direction to provide a track for the left window 12 and the right window 13 to perform left and right rotation, that is, circumferential rotation; the transparent observation port 14 is arranged on the upper surface of the emergency stop cover and corresponds to the boss 11 located therebelow.

[0040] Referring to Figure 2, the emergency stop upper cover is, for example, a cylindrical structure with a variable diameter, in which a lower cylinder with a relatively small diameter is fitted inside the emergency stop seat and transmits the downward pressing action to the emergency stop action trigger mechanism installed on the lower side of the emergency stop seat, thereby triggering the emergency stop of the relevant equipment.

[0041] Through the above conception, when performing an emergency stop operation, by pressing the emergency stop cover downward, the boss will move upward along the first slide and push the left window and the right window to the horizontal sides, and the upper surface of the boss with a first indicator symbol (for example, OFF) will be exposed in the transparent observation port; and when the emergency stop is canceled, by pressing and rotating the emergency stop cover, the left window and the right window will rotate in the circumferential direction under the action of the torsion spring and push the boss to move downward, and the upper surface of the left window and / or the right window with a second indicator symbol (for example, ON) will be exposed in the transparent observation port.

[0042] According to a preferred embodiment of the present invention, the horizontal cross-section of the boss 11 is preferably in the shape of an arc surface, and its two side inclined portions are respectively pressed against the first ends of the left window 12 and the right window 13; the upper sides of the left window 12 and the right window 13 are respectively provided with a horizontal protrusion, which is used to block the upper surface of the boss when not in an emergency stop state.

[0043] According to another preferred embodiment of the present invention, a mounting seat is preferably provided in the center of the emergency stop cover, and the outer surface of the mounting seat cooperates with the inner surface of the emergency stop cover to mount the first slideway and the second slideway. Figure 6 As shown in , the outer surface of the mounting seat is further provided with a protruding limiting rib 112, and the boss is provided with a corresponding limiting groove 111, thereby ensuring that the boss 11 can only move up and down without rotating or moving left and right.

[0044] The use process of the emergency stop button of the present invention will be specifically explained below.

[0045] like Figure 3a and 3bSee also Figure 4a and 4b When an emergency stop operation is required, by pressing the emergency stop upper cover downward, the boss will move upward along the first slide and push the left window and the right window to both sides horizontally, and the upper surface of the boss with the first indicator symbol will be exposed in the transparent observation port; then, the emergency stop upper cover will transmit the downward pressing action to the emergency stop action trigger mechanism installed on the lower side of the emergency stop seat, thereby triggering the emergency stop of the relevant equipment.

[0046] When the emergency stop is canceled, the emergency stop cover can be pressed and rotated, and the left window and the right window will rotate in a circular direction under the action of the torsion spring and push the boss to move downward. At this time, the boss can no longer support the left window and the right window, thereby exposing the upper surface of the left window and / or the right window with the second indicator symbol in the transparent observation port.

[0047] See also Figure 5a , showing the situation that the boss moves upward to the right position and pushes the left window and the right window to the horizontal sides. At this time, only the first indicator symbol (OFF) can be seen from the transparent observation port; see Figure 5b , showing the situation where the left window and the right window are rotated in the circumferential direction and the boss moves downward, at which time only the second indicator symbol (ON) can be seen through the transparent observation port.

[0048] In summary, the emergency stop button according to the present invention can realize the status display of the emergency stop button in a safe, reliable and easy-to-operate mechanical manner without using any indicator light. At the same time, it has the advantages of compact structure and good environmental adaptability. Therefore, it is particularly suitable for application occasions such as cabinets for ship equipment, and has good practical value and application prospects.

[0049] It will be easily understood by those skilled in the art that the above description is only a preferred embodiment of the present application and is not intended to limit the present application. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present application shall be included in the scope of protection of the present application.
