Abstract
Description
Technical Field
[0001] This utility model relates to the field of outdoor sports equipment technology, specifically to a mountaineering safety buckle designed to prevent accidental opening. Background Technology
[0002] As a core safety connector in outdoor sports such as rock climbing, hiking, and rescue, the reliability of carabiners directly affects the safety of users. Existing carabiners mainly consist of a C-ring, a locking bar assembly, and a limiting protection mechanism, with the C-ring serving as the main load-bearing component. One end of the locking bar assembly is hinged to the C-ring, and the other end engages with it, forming an openable and closable loop. The limiting protection mechanism includes a rotatable limiting sleeve mounted on the locking bar and a return spring. The limiting sleeve, under the action of the spring, maintains its position by blocking the engaged end. Although the above structure provides basic protection through spring return, the preload of the return spring is usually small. In actual use, when the limiting sleeve is subjected to external forces such as user misoperation, rock wall protrusions, or scratches from the body, it is prone to rotational displacement, thereby exposing the engaged end and increasing the risk of disengagement, posing a certain safety hazard. Utility Model Content
[0003] In view of this, the purpose of this utility model is to provide a mountain climbing safety buckle that prevents accidental opening.
[0004] To achieve the above objectives, this utility model provides the following technical solution: A mountaineering safety buckle to prevent accidental opening includes a buckle ring, a locking rod, and a limiting sleeve rotatably fitted onto the locking rod. The locking rod is provided with an elastic locking mechanism, which includes a mounting hole, an elastic element, and a limiting pin. The mounting hole is radially opened along the locking rod, and the elastic element and the limiting pin are sequentially arranged within the mounting hole, with the outer end of the limiting pin protruding from the surface of the locking rod. The side wall of the limiting sleeve has a locking hole adapted to the outer end of the limiting pin.
[0005] Furthermore, a limiting ring is provided in the middle of the limiting pin, and the outer diameter of the limiting ring is larger than the diameter of the lock hole.
[0006] Furthermore, the elastic element is a spring.
[0007] Furthermore, one end of the locking rod is rotatably connected to one end of the buckle via a connecting shaft, and a strip hole is provided on the side wall of the limiting sleeve along the circumference. The end of the connecting shaft cooperates with the strip hole to form a circumferential limiting.
[0008] Furthermore, the other end of the locking rod is provided with a bayonet, and the other end of the buckle is provided with a snap-fit part that matches the bayonet; the end of the limiting sleeve near the bayonet is provided with a clearance opening.
[0009] This utility model's anti-accidental opening mountaineering safety buckle incorporates an elastic locking mechanism. When the limiting sleeve is in the protective state, this mechanism can completely lock the circumferential rotational freedom of the limiting sleeve. Even if due to misoperation or external forces such as rock wall protrusions or human scratches, the limiting sleeve will not rotate or shift, thus effectively avoiding the risk of disengagement and further improving safety.

Detailed Implementation
[0016] The present invention will be further described below with reference to the accompanying drawings and specific embodiments, so that those skilled in the art can better understand and implement the present invention. However, the embodiments are not intended to limit the present invention.
[0017] like Figures 1 to 4 As shown, this utility model discloses a climbing safety buckle to prevent accidental opening, comprising a C-shaped buckle ring 1, a locking rod 2, and a limiting sleeve 3 rotatably fitted onto the locking rod 2. The locking rod 2 is provided with an elastic locking mechanism, which includes a mounting hole 21, an elastic element 22, and a limiting pin 23. The mounting hole 21 is radially opened along the locking rod 2, and the elastic element 22 and the limiting pin 23 are sequentially arranged within the mounting hole 21, with the outer end of the limiting pin 23 protruding from the surface of the locking rod 2. The side wall of the limiting sleeve 3 has a locking hole 31 adapted to the outer end of the limiting pin 23.
[0018] When the safety buckle is closed, the locking rod 2 and the locking ring 1 engage, and the limiting sleeve 3 rotates back to its initial position (i.e., the protective position). At this time, the limiting pin 23 is axially aligned with the locking hole 31 on the limiting sleeve 3. The outer end of the limiting pin 23 automatically engages with the locking hole 31 under the action of the elastic element 22, forming a mechanical limiting fit, thereby locking the circumferential rotational freedom of the limiting sleeve 3. Even if due to misoperation or external forces such as rock wall protrusions or human scratches, the limiting sleeve 3 will not rotate or shift, effectively avoiding the risk of disengagement and significantly improving safety.
[0019] When the safety lock needs to be opened, simply press down on the limiting pin 23 to disengage it from the lock hole 31, thus releasing the lock on the limiting sleeve 3. This can be done using a special tool, key, or a thin rod-like object to press down on the limiting pin 23. Then, rotate the limiting sleeve 3 to the unlocked position to further separate the locking rod 2 from the latch ring 1, completing the opening operation of the safety lock. Furthermore, because the limiting pin 23 is small and embedded in the mounting hole 21 and the lock hole 31, it cannot be opened by hand alone, preventing accidental manual opening.
[0020] The limiting pin 23 has a limiting ring 231 in the middle. The outer diameter of the limiting ring 231 is larger than the diameter of the locking hole 31 so that the limiting ring 231 and the inner end face of the locking hole 31 form an axial limit to prevent the limiting pin 23 from falling off.
[0021] In this embodiment, the elastic element 22 is a compression spring, and the compression spring and the limiting pin 23 are coaxially arranged in the mounting hole 21. The compression spring can be located at the bottom of the limiting pin 23, or it can be sleeved on the limiting pin 23 and contact the limiting ring 231. In its natural state, the compression spring pushes the limiting pin 23 outward by its elastic restoring force, so that the outer end of the limiting pin 23 forms a limiting engagement with the locking hole 31 of the limiting sleeve 3.
[0022] One end of the locking rod 2 is rotatably connected to one end of the buckle 1 via the connecting shaft 4. The side wall of the limiting sleeve 3 is provided with a strip hole 32 along the circumference. The end of the connecting shaft 4 cooperates with the strip hole 32 to form a circumferential limit, so that the limiting sleeve 3 can rotate around the axis of the locking rod 2 within a preset angle range.
[0023] The other end of the locking rod 2 is provided with a latch 24, and the other end of the buckle 1 is provided with a snap-fit part 11 that is adapted to the latch 24; the end of the limiting sleeve 3 near the latch 24 is provided with a clearance opening 33. When the limiting sleeve 3 is in the protective position, the clearance opening 33 is offset from the latch 24 to block the snap-fit part 11. When it is necessary to open the buckle, the limiting sleeve 3 is rotated until the clearance opening 33 is flush with the latch 24, so that the locking rod 2 can be rotated to open the buckle.
[0024] Other components required for carabiners, such as the return spring structure that enables the limit sleeve and locking bar to automatically reset, can adopt existing structures and will not be described in detail here.
[0025] This utility model's anti-accidental opening mountaineering safety buckle incorporates an elastic locking mechanism. When the limiting sleeve is in the protective state, this mechanism can completely lock the circumferential rotational freedom of the limiting sleeve. Even if due to misoperation or external forces such as rock wall protrusions or human scratches, the limiting sleeve will not rotate or shift, thus effectively avoiding the risk of disengagement and further improving safety.
[0026] The above-described embodiments are merely preferred embodiments provided to fully illustrate the present invention, and the scope of protection of the present invention is not limited thereto. Equivalent substitutions or modifications made by those skilled in the art based on the present invention are all within the scope of protection of the present invention. The scope of protection of the present invention is defined by the claims.
