Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of switch positioning pins, in particular to a switch positioning pin. Background Art
[0002] An isolating switch is a switch used to isolate a circuit or device, disconnecting it from the power source to ensure safe operation or maintenance. Isolating switches are commonly used in industrial applications, particularly to ensure a completely safe circuit during equipment repair or component replacement. They also prevent the flow of current in the circuit, thereby preventing accidental electric shock or damage to equipment. Isolating switches typically feature clear markings and handles for ease of use. Isolating switch locating pins are primarily used to position the isolating switch's operating handle to open and close the switch. Existing switch locating pins have at least the following drawbacks: Existing switch locating pins often have a lifting ring on the nut to facilitate removal and portability. However, due to the rigidity of the lifting ring, the nut can only be turned with a fixed or adjustable wrench, not a socket wrench. This limits the removal of the locating pin when tools are limited. Therefore, we have developed a switch locating pin. Utility Model Content
[0003] The main purpose of the utility model is to provide a switch positioning pin, which can effectively solve the problems in the background technology.
[0004] In order to achieve the above purpose, the technical solution adopted by the utility model is:
[0005] A switch positioning pin comprises a threaded section, the upper end of which is fixedly connected to a pin head section, the lower end of which is fixedly connected to a nut section, an outer surface of which is sleeved with an angle adjustment mechanism, and an outer surface of which is threadedly connected to a protective sleeve.
[0006] Preferably, the angle adjustment mechanism includes a connecting ring with a circular groove formed inside the connecting ring, a connecting rod fixedly connected to the right part of the outer surface of the connecting ring, a rotating rod movably connected to the outer surface of the connecting rod through a bearing, a through hole formed inside the rotating rod, and a hanging ring movably connected to the through hole.
[0007] Preferably, a notch is provided on the upper portion of the outer surface of the nut segment.
[0008] Preferably, the connecting ring is movably connected to the notch through insertion.
[0009] Preferably, the connecting ring does not extend out of the slot, and the connecting rod and the rotating rod extend out of the slot.
[0010] Preferably, a plurality of anti-slip grooves are provided on the outer surface of the protective sleeve, and an internal thread is provided at the lower end of the protective sleeve.
[0011] Preferably, the protective sleeve is threadedly connected to the threaded section via an internal thread, and the pin head section is located inside the protective sleeve.
[0012] Compared with the prior art, the present invention has the following beneficial effects:
[0013] 1. By setting up an angle adjustment mechanism, the connecting ring is connected to the notch on the nut segment, so that the connecting rod, rotating rod and lifting ring can be adjusted, which improves the flexibility of the lifting ring. Since the connecting ring is located above the nut segment and does not extend out of the notch, the socket wrench can be connected to the nut segment and twisted, which improves convenience.
[0014] 2. By setting a protective sleeve, the protective sleeve is threadedly connected to the threaded section so that the protective sleeve wraps the pin head section and the threaded section, thereby protecting the threaded section and the pin head section when not in use, and preventing the threaded section from being bumped and deformed.

They are not intended to indicate or imply that the devices or components referred to must have a specific orientation, be constructed, or operate in a specific orientation. Therefore, they should not be construed as limitations on this utility model. Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.
[0022] In the description of this utility model, it should be noted that, unless otherwise expressly specified or limited, the terms "installed," "provided with," "connected," etc. should be understood in a broad sense. For example, "connected" can mean a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium, or it can be internal communication between two components. Those skilled in the art will be able to understand the specific meanings of the above terms in this utility model based on the specific circumstances.
[0023] See also Figure 1-4 , the utility model provides a technical solution:
[0024] A switch positioning pin includes a threaded section 1, a pin head section 2 is fixedly connected to the upper end of the threaded section 1, a nut section 5 is fixedly connected to the lower end of the threaded section 1, an angle adjustment mechanism 4 is sleeved on the outer surface of the nut section 5, and a protective sleeve 3 is threadedly connected to the outer surface of the threaded section 1.
