Description

Technical Field

[0001] The utility model belongs to the field of emergency switches, and more particularly, relates to an emergency switch with a shielding component. Background Art

[0002] The primary function of an emergency switch is to provide rapid control and safety in an emergency. Typically used to control the main switch of a secondary circuit, an emergency switch can quickly cut off power or activate equipment in an emergency to prevent accidents or provide emergency assistance.

[0003] Emergency switches require high speed activation, so they often use a push-to-start mechanism consisting of an operating lever and a button cap. To facilitate the lever's telescopic movement, a gap is created between the operating lever and the housing. However, this gap allows external impurities such as moisture and dust to easily enter the housing, causing problems such as rust, jamming, and reduced sensitivity, affecting the emergency switch's proper operation.

[0004] To address this issue, the existing solution is to place the emergency switch inside a protective shell to shield the emergency switch. However, this design also reduces the activation speed of the emergency switch and makes it difficult to dissipate heat outward, which still affects the normal use of the emergency switch and requires further improvement. Utility Model Content

[0005] The utility model aims to solve the problem that the existing emergency switch is shielded by a protective shell, which leads to a reduced start-up speed and inconvenience in heat dissipation.

[0006] In order to achieve the above-mentioned object, the utility model provides an emergency switch with a shielding assembly, comprising:

[0007] The emergency switch body comprises a housing and an operating rod with its lower end inserted into the housing, and a button cap is sleeved on the upper end of the operating rod;

[0008] A shielding assembly is sleeved on the operating rod at the lower end of the button cap, and includes a protective cover, a spring, and an annular baffle arranged in sequence from top to bottom, and an extension portion is provided along the circumference of the lower end of the baffle;

[0009] The limiting assembly includes a first limiting plate and a second limiting plate which are relatively arranged on both sides of the operating rod and are configured to be able to move relative to or toward each other. The first limiting plate and the second limiting plate are both used to limit the extension part to the upper surface of the shell.

[0010] Optionally, the cross-section of the protective cover is in an inverted U shape.

[0011] Optionally, the upper end of the baffle exceeds the horizontal plane where the lower end of the protective cover is located.

[0012] Optionally, the first limiting plate and the second limiting plate are both arc-shaped.

[0013] Optionally, a connecting ring for connecting to the spring is provided inside the protective cover.

[0014] Optionally, the limiting assembly further includes a driving assembly for driving the first limiting plate and the second limiting plate to move relative to or toward each other.

[0015] Optionally, the drive assembly includes a first support and a second support symmetrically arranged on the upper surface of the shell, a first fastener and a second fastener, the first fastener and the second fastener are respectively arranged through the first support and the second support, and one end of the two extends into the first limit plate and the second limit plate respectively.

[0016] Optionally, both the first fastener and the second fastener are screws.

[0017] The beneficial effects of the present invention are:

[0018] The emergency switch with a shielding assembly proposed in this utility model is constructed by attaching a shielding assembly to the operating rod at the lower end of the button cap, and using a first limit plate and a second limit plate to limit the extension portion to the upper surface of the housing. This allows the shielding assembly to block the gap between the operating rod and the housing. At the same time, the protective cover can block and drain external moisture or dust, effectively preventing it from entering the interior of the housing through the gap. Compared with existing emergency switches, the emergency switch of this utility model can be activated quickly, and heat is dissipated through the gap between the protective cover and the baffle, thereby ensuring the normal use of the emergency switch.

[0019] According to the above content, the present invention can effectively solve the problem that the existing emergency switch is shielded by a protective shell, resulting in reduced startup speed and inconvenience in heat dissipation.

[0020] Other features and advantages of the present invention will be described in detail in the subsequent detailed description of the embodiments. BRIEF DESCRIPTION OF THE DRAWINGS

[0039] In order to enable those skilled in the art to more fully understand the technical solution of the present invention, the exemplary embodiments of the present invention will be described in more comprehensive and detailed in conjunction with the accompanying drawings below. Obviously, the one or more embodiments of the present invention described below are only one or more of the specific ways of implementing the technical solution of the present invention, and are not exhaustive. It should be understood that other ways belonging to a general utility model concept can be used to implement the technical solution of the present invention, and should not be limited by the exemplary embodiments described. Based on one or more embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative work should fall within the scope of protection of the present invention.

[0040] Example: Figure 1 A schematic structural diagram of an emergency switch with a shielding assembly according to an embodiment of the present utility model is shown; Figure 2 A cross-sectional view of a shielding assembly according to an embodiment of the present invention is shown.

[0041] Reference Figure 1-2 , an embodiment of the utility model provides an emergency switch with a shielding component, comprising:

[0042] The emergency switch body comprises a housing 1 and an operating rod 2 whose lower end is inserted into the housing 1, and a button cap 3 is sleeved on the upper end of the operating rod 2;

[0043] The shielding assembly is mounted on the operating rod 2 at the lower end of the button cap 3, and includes a protective cover 4, a spring 5, and an annular baffle 6 arranged in sequence from top to bottom. The lower end of the baffle 6 is provided with an extension portion 61 along its circumference;

[0044] The limiting assembly includes a first limiting plate 7 and a second limiting plate 8 which are relatively arranged on both sides of the operating rod 2 and are configured to be able to move relative to or towards each other. The first limiting plate 7 and the second limiting plate 8 are both used to limit the extension part 61 to the upper surface of the shell 1.

[0045] Specifically, there is a contact assembly inside the shell. When the operating lever is pressed so that the electrode sheet in the contact assembly is in contact, the terminal on the emergency switch body is electrically connected or disconnected with the external power supply equipment to quickly control the power supply or equipment. The specific structure of the contact assembly is existing technology and will not be repeated here.

[0046] In a specific embodiment, the cross section of the protective cover 4 is in the shape of an inverted U. The inverted U shape can guide external impurities outwards and prevent them from approaching the gaps in the housing.

[0047] In one embodiment, a connecting ring 41 for connecting to the spring 5 is provided inside the protective cover 4 .

[0048] In one embodiment, the upper end of the baffle 6 exceeds the horizontal plane where the lower end of the protective cover 4 is located.

[0049] Specifically, when external impurities fall on the protective cover, they will flow out along its outer wall to the lower side. The upper end of the baffle is set to exceed the horizontal plane of the lower end of the protective cover, so that the baffle can block the external impurities again and effectively prevent the entry of external impurities.

[0050] In a specific embodiment, the first limiting plate 7 and the second limiting plate 8 are both arc-shaped.

[0051] In one embodiment, the limiting assembly further includes a driving assembly for driving the first limiting plate 7 and the second limiting plate 8 to move relative to or toward each other.

[0052] In one embodiment, the driving assembly includes a first support 9 and a second support 10, a first fastener 11 and a second fastener 12 symmetrically arranged on the upper surface of the housing 1. The first fastener 11 and the second fastener 12 are respectively arranged through the first support 9 and the second support 10, and one end of the two extends into the first limit plate 7 and the second limit plate 8 respectively.

[0053] In a specific embodiment, the first fastener 11 and the second fastener 12 are both screws.

[0054] When the emergency switch of the utility model is activated, the button cap can be directly pressed. At this time, the protective cover moves downward along with the operating rod, compressing the spring to seal the gap between the housing and the telescopic rod. When the emergency switch is reset, the protective cover and the baffle can continuously cover the gap.

[0055] The emergency switch with a shielding assembly proposed by the utility model is equipped with a shielding assembly on the operating rod at the lower end of the button cap, and uses the first limit plate and the second limit plate to limit the extension part to the upper surface of the shell, so that the baffle can block the gap between the operating rod and the shell. At the same time, the protective cover can block and drain external moisture or dust, effectively preventing it from entering the interior of the shell through the gap.

[0056] Therefore, compared with the existing emergency switch, the emergency switch of the present invention can be quickly activated and dissipated through the gap between the protective cover and the baffle, thereby ensuring the normal use of the emergency switch.

[0057] Although one or more embodiments of the present invention have been described above, it should be understood by those skilled in the art that the present invention can be implemented in any other form without departing from its spirit and scope. Therefore, the embodiments described above are illustrative and not restrictive, and many modifications and substitutions will be apparent to those skilled in the art without departing from the spirit and scope of the present invention as defined in the appended claims.
