Description

Technical Field

[0001] This utility model relates to the field of outdoor equipment technology, and in particular to a carabiner with a disconnection alarm function. Background Technology

[0002] In mountaineering, rock climbing, exploration, and industrial high-altitude operations, carabiners serve as crucial connecting components, their performance directly impacting personnel safety and the smooth progress of work. With the increasing popularity and development of these activities, the requirements for carabiners are becoming increasingly stringent. To enhance safety, some carabiners employ a threaded locking structure, achieving a secure fit by rotating the threaded buckle, significantly improving their resistance to accidental opening. Chinese utility model patent CN212880881U discloses a design including an ear-shaped rod and an upper threaded rod. The ear-shaped rod has an upper threaded rod and a connecting clamp at its two ends, located at opposite ends. The upper threaded rod is integrally formed at the upper end of the ear-shaped rod, and the connecting clamp is integrally formed at the lower end. A U-shaped sleeve is provided at the top of the connecting clamp, and the U-shaped sleeve is movably connected to the connecting clamp via a mandrel. A lower threaded rod is provided at the top of the U-shaped sleeve, integrally formed thereon. A rotating sleeve is provided around the lower threaded rod, and the rotating sleeve is fastened to the lower threaded rod by the interlocking of the threads. A spring is provided at the top of the rotating sleeve outside the lower threaded rod. However, a new problem arises. In actual operation, it is difficult for users to determine whether the threads are fully tightened by touch or visual inspection alone. In dimly lit environments or emergency situations, this uncertainty is further amplified. If the buckle is not tightened, it may loosen or even break under significant tension, endangering the user's life. Summary of the Invention

[0003] The purpose of this invention is to provide a carabiner with a release alarm function. This invention allows for real-time feedback on the carabiner's status via indicator light switching in dimly lit environments, thus improving safety during use.

[0004] The technical solution of this utility model is as follows: A carabiner with a disconnection alarm function includes a ring body, an opening on one side of the ring body, a locking rod hinged to the lower end of the ring body at the opening, and a thread on the upper end of the ring body at the opening. A threaded fastener is fitted onto the locking rod, and the upper part of the threaded fastener engages with the thread of the ring body. The locking rod comprises a first outer shell hinged to an upward protrusion. A second outer shell and a third outer shell are sequentially arranged above the first outer shell, and the second outer shell is threadedly connected to the first outer shell. A battery compartment with a built-in battery is located at the bottom of the inner cavity of the second outer shell, and a circuit board is located above the battery compartment. A switching circuit is provided on the circuit board. A first indicator light and a second indicator light connected to the switching circuit are located outside the first outer shell. A first copper sheet is provided on the inner wall of the threaded fastener, and a second copper sheet is provided on the upper part of the side wall of the third outer shell. The first and second copper sheets are connected to the switching circuit. When the threaded fastener is screwed to the top of the downward protrusion, the first and second copper sheets contact each other, triggering the switching circuit to switch the conduction of the first and second indicator lights.

[0005] In the aforementioned carabiner with an escape alarm function, the switching circuit includes a voltage comparator U1, the output of which is connected to a first indicator light and a second indicator light; the first copper plate and the second copper plate are in contact, the voltage at the input of the voltage comparator U1 switches between high and low, and the level signal at the output of the voltage comparator U1 switches between high and low, thereby switching the conduction of the first indicator light and the second indicator light.

[0006] In the aforementioned carabiner with a disconnection alarm function, the switching circuit includes a voltage comparator U1. The positive input terminal of the voltage comparator U1 is connected to a first copper plate and a first resistor R1, which is grounded. The negative input terminal of the voltage comparator U1 is connected to a second resistor R2 and a third resistor R3, which is connected to a battery, while the second resistor R2 is grounded. The output terminal of the voltage comparator U1 is connected to a fourth resistor R4, which is connected to the input terminal of a first indicator light, whose output terminal is grounded. The fourth resistor R4 is also connected to the output terminal of a second indicator light, whose input terminal is connected to a battery. The second copper plate is also connected to the battery via a circuit.

[0007] In the aforementioned carabiner with a disengagement alarm function, the upward protrusion has a horizontally penetrating connecting hole, which is connected to the movement hole via a connecting rod. The movement hole is located at the end of the locking rod.

[0008] In the aforementioned carabiner with a disengagement alarm function, a raised limiting ring is provided on the first outer shell, and both the first indicator light and the second indicator light are located on the raised limiting ring.

[0009] In the aforementioned carabiner with an escape alarm function, the second outer shell has a horizontal plate with a circular threaded gap running through the middle of the plate.

[0010] In the aforementioned carabiner with an escape alarm function, the battery compartment is fixed upside down at the bottom of the horizontal plate, and the circuit board is fixed upright at the top of the horizontal plate.

[0011] In the aforementioned carabiner with a release alarm function, the ring body is a ring shape that is larger at the top and smaller at the bottom, and a flat strip-shaped easy-grip area is provided on the side.

[0012] In the aforementioned carabiner with an escape alarm function, the outer surface of the buckle is provided with a diamond-shaped anti-slip texture.

[0013] In the aforementioned carabiner with a disconnection alarm function, the battery compartment is compatible with a button battery. The battery compartment is equipped with a battery contact spring. When the battery is inserted and pressed down, it provides power. The top of the battery compartment is equipped with an anti-drop latch.

[0014] Compared with the prior art, the present invention has the following advantages:

[0015] 1. The first outer shell of this utility model is provided with a protruding limiting ring, on which a first indicator light and a second indicator light are provided. The output terminal of the voltage comparator U1 is connected to the first indicator light and the second indicator light. A first copper sheet is provided on the inner side wall of the thread, and a second copper sheet is provided on the upper part of the side wall of the third outer shell. The first copper sheet and the second copper sheet are connected to the switching circuit. When the thread is screwed to the top of the downward protrusion, the first copper sheet and the second copper sheet are in contact, the voltage at the input terminal of the voltage comparator U1 switches between high and low, the level signal at the output terminal of the voltage comparator U1 switches between high and low, and the operational amplifier outputs a high level, thereby switching the conduction of the first indicator light and the second indicator light, so the first indicator light is lit. When the thread is not screwed to the top of the downward protrusion, the first copper sheet and the second copper sheet are not in contact, the voltage at the input terminal of the voltage comparator U1 switches between high and low, the level signal at the output terminal of the voltage comparator U1 switches between high and low, and the operational amplifier outputs a low level, thereby switching the conduction of the first indicator light and the second indicator light, so the second indicator light is lit. In this way, the status of the carabiner can be fed back in real time through the switching of indicator lights in dim environments, effectively avoiding safety hazards caused by the carabiner not being locked properly, and achieving the effect of ensuring user safety.

[0016] 2. The second outer shell of this utility model has a horizontal plate inside, with a circular wire-passing gap running through the middle of the horizontal plate. The battery compartment is fixed upside down at the bottom of the horizontal plate, and the circuit board is fixed upright at the top of the horizontal plate. Through the layered structure separated by the horizontal plate, electronic components such as the battery, battery compartment, and circuit board are rationally arranged. The design of the battery compartment being upside down and the circuit board being upright achieves the effect of effectively utilizing the internal space, and is compatible with button batteries, making it easy to replace and maintain. The upside-down fixing of the battery compartment to the bottom of the horizontal plate also prevents the button batteries inside the battery compartment from being accidentally knocked out when the second outer shell is removed from the first outer shell, reducing the trouble of searching for them and thus protecting the button batteries and the environment.

Detailed Implementation

[0027] The present invention will be further described below with reference to the accompanying drawings and embodiments, but this should not be construed as limiting the present invention.

[0028] Example: A carabiner with a disconnection alarm function, configured as follows Figure 1-8As shown, it includes a ring 101, which is a ring shape that is wider at the top and narrower at the bottom. A flat, easy-grip area 108 is provided on the side. The presence of the easy-grip area 108 improves the user's operating experience and reduces slippage. For everyday outdoor use, 7075 aluminum alloy is the preferred material for the ring 101. For products with CE / UIAA certification, 304 stainless steel or alloy steel are considered for extreme environments, but this requires accepting an increase in weight. When lightweighting is a priority, 7075 aluminum alloy is the only option, such as ultralight models weighing less than 30 grams (like the Camp Nano). 22) An opening 102 is provided on one side of the ring 101. A matching locking rod 201 and a thread 301 are provided at the opening 102. The two ends of the opening 102 have opposing protrusions, which are symmetrical to each other and each is a right trapezoid. The opposing protrusions include a downward protrusion 103 and an upward protrusion 104. The downward protrusion 103 at the upper end of the opening 102 has threads on both sides. The lower end of the opening 102 has an upward protrusion 104. The upper part of the upward protrusion 104 has a transverse through-hole 105. The through-hole 105 is connected to the movement hole 107 through a connecting rod 106. The two ends of the connecting rod 106 have protrusions that are slightly larger than the rod body to ensure movement. The stable connection between hole 107 and connecting hole 105 reduces mechanical wear and extends the service life of the carabiner. The movement hole 107 is located at the end of the locking bar 201, allowing the locking bar 201 to rotate at a fixed point within a range with the threaded buckle 301 under the limitation of the connecting hole 105, connecting rod 106 and movement hole 107. The threaded buckle 301 is sleeved on the outside of the locking bar 201 and slides on the locking bar 201. The upper inner side of the threaded buckle 301 is provided with threads that match the threads on both sides of the downward protrusion 103. The outer side of the threaded buckle 301 is provided with friction texture to optimize the user's operating experience. Even when wearing gloves, the threaded buckle can be easily rotated to complete the opening and closing, taking into account both convenience and anti-slip properties.

[0029] like Figure 3-9As shown: The locking lever 201 includes a first outer shell 215 hinged to the upward protrusion 104. A protruding limiting ring 202 is provided at the top of the first outer shell 215. The limiting ring 202 is a protruding circular ring. A first indicator light 2031 and a second indicator light 2032 are both located on the protruding limiting ring 202. A second outer shell 216 and a third outer shell 217 are sequentially arranged above the first outer shell 215. The second outer shell 216 is threadedly connected to the first outer shell 215. A battery compartment 205 with a built-in battery is located at the bottom of the inner cavity of the second outer shell 216. A circuit board 206 is located above the battery compartment 205. A switching circuit is provided on the circuit board 206, including a voltage comparison circuit. The voltage comparator U1 has a positive input terminal connected to a first copper plate 209 and a first resistor R1, which is grounded. The negative input terminal of the voltage comparator U1 is connected to a second resistor R2 and a third resistor R3, with the third resistor R3 connected to a battery and the second resistor R2 grounded. The output terminal of the voltage comparator U1 is connected to a fourth resistor R4, which is connected to the input terminal of a first indicator light 2031, whose output terminal is grounded. The fourth resistor R4 is also connected to the output terminal of a second indicator light 2032, whose input terminal is connected to a battery. The second copper plate 210 is also connected to the battery via a circuit. The inner wall of the screw thread 301 is provided with a first copper piece 209, and the upper part of the side wall of the third housing 217 is provided with a second copper piece 210. The first copper piece 209 and the second copper piece 210 are connected to the switching circuit. When the screw thread 301 is screwed to the top of the downward protrusion 103, the first copper piece 209 and the second copper piece 210 are in contact, the voltage at the input terminal of the voltage comparator U1 switches between high and low, the level signal at the output terminal of the voltage comparator U1 switches between high and low, and the operational amplifier outputs a high level, thereby switching the conduction of the first indicator light 2031 and the second indicator light 2032, so the first indicator light 2031 is lit. When the screw thread 301 is not screwed to the top of the downward protrusion 103, the first copper piece 209 and the second copper piece 210 are not in contact, the voltage at the input terminal of the voltage comparator U1 switches between high and low, the level signal at the output terminal of the voltage comparator U1 switches between high and low, and the operational amplifier outputs a low level, thereby switching the conduction of the first indicator light 2031 and the second indicator light 2032, so the second indicator light 2032 is lit. In this way, the status of the carabiner can be fed back in real time through the switching of indicator lights in dim environments, effectively avoiding safety hazards caused by the carabiner not being locked properly, thus ensuring user safety and improving user security during use.

[0030] like Figure 4-6As shown: The internal threads at the bottom of the second housing 216 are compatible with the protruding threads on the upper part of the limiting ring 202. When replacement or maintenance is needed, simply rotate the second housing 216 to unscrew it from the protruding threads on the upper part of the limiting ring 202 for convenient and quick replacement or maintenance. The second housing 216 has a horizontal plate 212 with a wire-passing gap 213 in the middle. The wire-passing gap 213 is circular, allowing the wire harness to pass through and connect the battery, circuit board 206, etc., for power supply. The battery compartment 205 is fixed upside down at the bottom of the horizontal plate 212. The battery compartment 205 is compatible with button batteries and has a battery contact spring inside. Power is supplied after the battery is inserted and pressed down. The top of the battery compartment 205 has an anti-drop latch. The circuit board 206 is fixed upright at the top of the horizontal plate 212 for detecting whether the carabiner is locked, which is convenient for use. The layered structure separated by horizontal plates allows for a rational arrangement of electronic components such as batteries, battery compartments, and circuit boards, effectively utilizing internal space and facilitating replacement and maintenance. The battery compartment's inverted position at the bottom of the horizontal plate prevents accidental dislodgement of the button battery when removing the second outer casing from the first, reducing the hassle of searching and protecting the button battery and the environment. It should be noted that, as a preferred embodiment, the battery compartment 205 can also house a lithium battery for charging via a charging port; alternatively, a wireless charging module can be incorporated for wireless charging, improving practicality and convenience. As another preferred embodiment, the upper middle part of the second outer casing 216 can be painted green, and the third outer casing 217 can be painted red. When the screw 301 is fully engaged, the red portion of the third outer casing 217 is obscured, while the green portion of the upper middle part of the second outer casing 216 is fully exposed, indicating that the screw 301 is fully secured. Conversely, if some of the red portion of the third outer casing 217 is exposed, it indicates that the screw 301 is not fully tightened and the fixation is inadequate. The above design can provide auxiliary judgment when the battery compartment 205 is out of power.

[0031] like Figure 3 As shown: The upper part of the locking rod 201 is provided with a downward limiting groove 207 that matches the downward protrusion 103; the lower part of the locking rod 201 is provided with an upward limiting groove 214 that matches the upward protrusion 104.
