Description

Technical Field

[0001] The utility model relates to an emergency stop button, in particular to an emergency stop button with excellent waterproof performance, and belongs to the technical field of buttons. Background Art

[0002] At present, emergency stop buttons are one of the common components on equipment. When a malfunction or accident occurs during the operation of the equipment, pressing the emergency stop button will stop the equipment from running. For equipment installed outdoors, these emergency stop buttons need to be waterproof to prevent water from entering and affecting their internal electrical performance. For this purpose, our company has developed and applied for Chinese patent CN2024203504911 "Compact waterproof emergency stop button", which enhances the waterproof capability by combining a "waterproof plug" structure at the bottom with a wiring harness connection instead of a plug-in connection. However, in actual application, it was found that the waterproof performance of the above structure needs to be improved: it is impossible to achieve a complete seal when the wiring harness passes through the bottom of the base, so there are defects in situations where the bottom of the base needs to be fully sealed; in addition, the protection level at the mushroom head is not high enough. In outdoor applications, trace amounts of moisture will inevitably enter the mushroom head, thereby affecting the contact assembly. For this reason, it is necessary to design an emergency stop button with a higher protection level. Summary of the Invention

[0003] The purpose of the utility model is to overcome the above-mentioned shortcomings and provide a fully waterproof emergency stop button with better waterproof performance.

[0004] The purpose of this utility model is achieved in this way:

[0005] A fully waterproof emergency stop button comprises a base, wherein a waterproof plug is embedded in the bottom of the base, a contact piece is located in the base and embedded in the waterproof plug, and the conductive cable of the contact piece is led out through the threading hole on the bottom surface of the waterproof plug; a contact piece is inserted in the upper part of the base, and there is a flexible sealing airbag, the open end of the flexible sealing airbag covers the waterproof plug at the bottom of the base, and the conductive cable passing through the waterproof plug is led out through the flexible sealing airbag; the open end of the flexible sealing airbag is folded inward to form a flange with an annular structure, and an annular groove with an annular structure is provided in the middle of the outer wall of the waterproof plug, and the flange is embedded in the annular groove.

[0006] A fully waterproof emergency stop button comprises a base, a waterproof plug is embedded in the bottom of the base, a contact piece is located in the base and embedded in the waterproof plug, and the conductive cable of the contact piece is led out through the threading hole on the bottom surface of the waterproof plug; a contact piece is inserted in the upper part of the base, and there is a waterproof pad, which is pressed between the contact piece and the pressing piece; the edges of the waterproof pad are pressed between the step surface and the contact piece, and the middle part of the waterproof pad protrudes upward to form a boss structure; a plurality of water outlet holes connected to the inner cavity of the base are provided on the outer wall of the base, and the water outlet holes are located above the waterproof pad.

[0007] A fully waterproof emergency stop button includes a base, a waterproof plug is embedded in the bottom of the base, a contact piece is located in the base and embedded in the waterproof plug, and the conductive cable of the contact piece is led out through the threading hole on the bottom surface of the waterproof plug; a contact piece is inserted in the upper part of the base, and there is a flexible sealing airbag, the open end of the flexible sealing airbag covers the waterproof plug at the bottom of the base, and the conductive cable passing through the waterproof plug is led out through the flexible sealing airbag; there is a waterproof pad, which is pressed between the contact piece and the pressing piece.

[0008] Preferably, the flexible sealing airbag is made of rubber.

[0009] Compared with the prior art, the beneficial effects of the present invention are:

[0010] The utility model increases waterproofing capabilities by installing a flexible sealing airbag at the bottom. The advantage of using a flexible sealing airbag is that when the mushroom head of the button is pressed, the internal space shrinks and the internal air is pressurized, which inevitably overflows from the gap, causing the internal space of the button to be in a slightly negative pressure state, thereby affecting its automatic reset or failing to reset it properly, affecting subsequent work. It is often necessary to manually pull it up or rotate it to ensure its reset, which seriously affects its reliability. The design of the flexible sealing airbag can store the gas discharged through the threading hole to form a pressurized structure. Therefore, when resetting, the air at a slightly positive pressure in the flexible sealing airbag can be filled into the base to avoid the formation of negative pressure, ensuring the reliability of the reset.

[0011] Alternatively, the utility model achieves focused sealing protection for the contact parts by installing a waterproof pad installed in the base at the bottom. At this time, the water entering the base can be promptly discharged through the water outlet hole to prevent it from invading and breaking through the waterproof pad; and by changing the installation position of the reset spring, its weather resistance can also be improved, which is beneficial to increasing its service life.

[0017] Base 1, contact member 2, waterproof pad 3, pressing member 4, mushroom head 5, waterproof plug 6, flexible sealing airbag 7;

[0018] Step surface 1.1, water outlet 1.2;

[0019] Return spring 2.1, conductive cable 2.2;

[0020] Annular slot 6.1, threading hole 6.2;

[0021] Flanging 7.1. DETAILED DESCRIPTION Example 1:

[0022] See also Figure 1 and Figure 2 The utility model relates to a fully waterproof emergency stop button, which includes a base 1, a waterproof plug 6 is embedded in the bottom of the base 1, a contact member 2 is located in the base 1 and embedded in the waterproof plug 6, and the conductive cable 2.2 of the contact member 2 is led out through the threading hole 6.2 on the bottom surface of the waterproof plug 6; a pressing member 4 with which the contact member 2 slides is inserted in the upper part of the base 1, and the top of the pressing member 4 is connected to a mushroom head 5 located outside the base 1. The pressing member 4 and the mushroom head 5 can be an integrated structure or a split structure.

[0023] To improve sealing performance, a flexible sealing bladder 7 (which can be made of an elastic material such as rubber) is added. An annular groove 6.1 is provided in the middle of the outer wall of the waterproof plug 6. The open end of the flexible sealing bladder 7 is folded inward to form an annular flange 7.1. The flange 7.1 is embedded in the annular groove 6.1, and the open end of the flexible sealing bladder 7 is engaged between the outer wall of the waterproof plug 6 and the inner wall of the base 1 near the flange 7.1. The design of the flexible sealing bladder 7 allows the compressed air to enter the flexible sealing bladder 7 through the threading hole 6.2 (i.e., through the gap between the conductive cable 2.2 and the threading hole 6.2) during the pressing of the pressing member 4, forming a slight positive pressure. When the hand releases the mushroom head 5, that is, when no pressure is applied to the pressing member 4, the pressing member 4 is reset downward under the force of the reset spring 2.1. The slightly positive pressure of the air in the flexible sealing bladder 7 can then be filled into the base 1 to prevent the formation of a negative pressure, thereby ensuring the normal reset of the contact member 2. At the same time, a plunger 8 is embedded in the bottom of the flexible sealing airbag 7 , and the cable passing through the waterproof plug 6 is led out through the plunger 8 . Example 2:

[0024] See also Figure 3 and Figure 4The utility model relates to a fully waterproof emergency stop button, which includes a base 1, a waterproof plug 6 is embedded in the bottom of the base 1, a contact member 2 is located in the base 1 and embedded in the waterproof plug 6, and the conductive cable 2.2 of the contact member 2 is led out through the threading hole 6.2 on the bottom surface of the waterproof plug 6; and a step surface 1.1 is provided on the inner wall of the base 1, and the top of the waterproof plug 6 rests on the step surface 1.1.

[0025] A pressing member 4 that slides in contact with the contact member 2 is inserted into the upper portion of the base 1 , and the top of the pressing member 4 is connected to a mushroom head 5 located outside the base 1 . The pressing member 4 and the mushroom head 5 can be an integrated structure or a split structure.

[0026] To improve the sealing performance: add a waterproof pad 3, the waterproof pad 3 is located between the contact piece 2 and the pressing piece 4, the edges of the waterproof pad 3 are pressed between the step surface 1.1 and the contact piece 2, and the middle part of the waterproof pad 3 protrudes upward to form a boss structure 3.1, the contact piece 2 is located in the groove below the boss structure 3.1, and the pressing piece 4 is connected to the top upper surface of the boss structure 3.1. The purpose of setting the boss structure 3.1 is to provide the waterproof pad 3 with more deformation stroke, so as to ensure that the waterproof pad 3 will not be damaged due to deformation when pressing during daily use of the button.

[0027] At the same time, a plurality of water outlet holes 1.2 connected to the inner cavity of the base 1 are provided on the outer wall of the base 1, and the water outlet holes 1.2 are located above the waterproof pad 3, which can be used to discharge the water entering the base 1 in time.

[0028] Moreover, at this time, the return spring 2.1 needs to be installed in the closed space between the waterproof pad 3 and the waterproof plug 6. Compared with the conventional return spring 2.1 located in the upper space of the base 1 and directly acting on the pressing part 4, after the return spring 2.1 is located in the closed space, it is not easy to rust due to the humid environment and other conditions that affect its elasticity. Example 3:

[0029] Embodiment 3 is a combination of embodiment 1 and embodiment 2. The utility model relates to a fully waterproof emergency stop button, which includes a base 1, a waterproof plug 6 is embedded in the bottom of the base 1, and the contact member 2 is located in the base 1 and embedded in the waterproof plug 6. A reset spring 2.1 is provided between the contact member 2 and the bottom surface of the waterproof plug 6, and the conductive cable 2.2 of the contact member 2 is led out through the threading hole 6.2 on the bottom surface of the waterproof plug 6; and a step surface 1.1 is provided on the inner wall of the base 1, and the top of the waterproof plug 6 rests on the step surface 1.1.

[0030] A pressing member 4 that slides in contact with the contact member 2 is inserted into the upper portion of the base 1 , and the top of the pressing member 4 is connected to a mushroom head 5 located outside the base 1 . The pressing member 4 and the mushroom head 5 can be an integrated structure or a split structure.

[0031] There is a waterproof pad 3, which is located between the contact member 2 and the pressing member 4. The edges of the waterproof pad 3 are pressed between the step surface 1.1 and the contact member 2, and the middle part of the waterproof pad 3 is raised upward to form a boss structure 3.1. The contact member 2 is located in a groove below the boss structure 3.1, and the pressing member 4 is connected to the top upper surface of the boss structure 3.1. The purpose of providing the boss structure 3.1 is to provide the waterproof pad 3 with more deformation travel, thereby ensuring that the waterproof pad 3 will not be damaged due to deformation during daily use of the button. At the same time, a plurality of water outlet holes 1.2 connected to the inner cavity of the base 1 are provided on the outer wall of the base 1. The water outlet holes 1.2 are located above the waterproof pad 3 and can be used to promptly discharge water that enters the base 1. Moreover, at this time, the return spring 2.1 needs to be installed in the closed space between the waterproof pad 3 and the waterproof plug 6. Compared with the conventional return spring 2.1 located in the upper space of the base 1 and directly acting on the pressing part 4, after the return spring 2.1 is located in the closed space, it is not easy to rust due to the humid environment and other conditions that affect its elasticity.

[0032] A flexible sealing airbag 7 (which can be made of an elastic material such as rubber) is provided in the middle of the outer wall of the waterproof plug 6. An annular groove 6.1 is provided. The open end of the flexible sealing airbag 7 is folded inward to form an annular flange 7.1. The flange 7.1 is embedded in the annular groove 6.1, and the open end of the flexible sealing airbag 7 is clamped between the outer wall of the waterproof plug 6 and the inner wall of the base 1 near the flange 7.1. Due to the design of the flexible sealing airbag 7, when the pressing member 4 is pressed, the squeezed air enters the flexible sealing airbag 7 through the threading hole 6.2 (i.e., through the gap between the conductive cable 2.2 and the threading hole 6.2) to form a slight positive pressure. When the hand releases the mushroom head 5, that is, when the pressure on the pressing member 4 is no longer applied, the pressing member 4 is reset downward under the action of the reset spring 2.1. At this time, the air at the slight positive pressure in the flexible sealing airbag 7 can be filled into the base 1 to prevent it from forming a negative pressure, thereby ensuring the normal reset of the contact member 2. At the same time, a plunger 8 is embedded in the bottom of the flexible sealing airbag 7 , and the cable passing through the waterproof plug 6 is led out through the plunger 8 .

[0033] In addition: It should be noted that the above specific implementation is only an optimization scheme of this patent. Any changes or improvements made by technicians in this field based on the above concept are within the scope of protection of this patent.
