Description

Technical Field

[0001] This utility model relates to the field of buckle testing, and in particular to a fatigue resistance testing device for carabiner main locks. Background Technology

[0002] Carabiners are connecting rings made of materials such as aluminum alloy and stainless steel, primarily used for suspending and securely connecting items in outdoor sports and rock climbing. Common shapes include D-shape, figure-eight shape, and racetrack shape. They possess high load-bearing capacity, and some products are equipped with locking mechanisms for enhanced security. Professional carabiners must be UIAA certified, with a maximum load capacity of over 22 kN, playing a crucial role in rope connections and equipment mounting.

[0003] To ensure the security of carabiners, a locking mechanism is disclosed in the prior art (Announcement No.: CN211635133U, Announcement Date: 2020.10.09), which releases the carabiner by twisting a rotating rod, and then pressing the rotating rod after twisting it opens the carabiner.

[0004] The prior art (announcement number: TWM591575U, announcement date: 2020.03.01) also discloses the structure of a button-type fixed safety hook, which opens the hook by twisting and pressing the locking sleeve. The double locking method prevents the hook from disengaging on its own, ensuring its safety and firmness.

[0005] In the prior art (announcement number: CN308099999S, announcement date: 2023.06.27), a ring-shaped opening is disclosed. Among them, design 2, design 3, design 5 and design 6 all use a method of rotating first and then pressing to open the fastener.

[0006] In all the above-mentioned fastener schemes, opening the fastener requires two actions: twisting and pressing. In order to ensure the stability and fatigue resistance of the fastener, it is necessary to design a fatigue resistance testing device for the main lock of the carabiner. This device can be used to test the service life of the fastener, ensure the quality of the fastener at the time of manufacture, and thus improve the safety factor of the fastener when it is used in scenarios such as rope connection and equipment mounting. Utility Model Content

[0007] To overcome the shortcomings mentioned above, this utility model provides a technical solution that can solve the above problems.

[0008] A fatigue resistance testing device for carabiner main lock includes a side plate and a lifting mechanism. Clamps are fixedly installed at both ends of the front side of the side plate, and a carabiner is clamped between the two clamps. A rotating part is provided on the upper side of the carabiner, and a pressure ring is sleeved on the outer side of the rotating part.

[0009] The front side of the lower pressure ring is formed with a lower pressure edge, and the bottom side of the lifting mechanism is connected to a lower pressure rod. The lower pressure rod presses on the lower pressure edge and the lower pressure ring, causing the rotating part to rotate and press.

[0010] Furthermore: the middle part of the pressing rod is formed with a right-angled side, which is located above the pressing ring. The bottom end of the pressing rod presses on the pressing ring, causing the rotating part to rotate. The right-angled side presses on the pressing ring, causing the rotating part to press.

[0011] Furthermore: the front side of the side plate is fixedly installed with a positioning bottom edge by screws, and both clamps are set above the positioning bottom edge, with the bottom side of the carabiner placed on the positioning bottom edge.

[0012] Furthermore, the two clamps are arranged symmetrically to each other.

[0013] Furthermore: the clamp includes a first clamping plate, a second clamping plate, and a locking bolt. The locking bolt passes through the second clamping plate and the first clamping plate in sequence and locks onto the side plate. The carabiner is clamped and fixed between the first clamping plate and the second clamping plate.

[0014] Furthermore, the clamp has at least two locking bolts.

[0015] Furthermore, a clearance groove is formed in the middle of the front side of the side plate, and the lower pressure ring is fitted into the clearance groove with a gap fit.

[0016] Furthermore: the lower pressure ring is formed with screw holes, and a positioning bolt is screwed into the screw holes. The inner end of the positioning bolt is pressed against the outer side of the rotating part for installation and locking.

[0017] Furthermore, the lower pressing edge and the screw hole are spaced apart vertically from each other.

[0018] Compared with the prior art, the beneficial effects of this utility model are as follows: First, the carabiner to be tested is clamped firmly by the clamps on both sides. The clamps can provide the carabiner with the function of installation and positioning. The rotating part of the carabiner needs to be rotated before it can be pressed open. At this time, the lifting mechanism drives the lower pressure rod to move continuously up and down. The lower pressure rod will press on the lower pressure ring and the lower pressure edge to drive the rotating part to rotate and press. The rotating part of the carabiner can elastically return to its original position after rotation and pressing, thereby realizing continuous rotation and pressing test of the carabiner and ensuring the fatigue strength of the main lock of the carabiner.

Detailed Implementation

[0026] The technical solution of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are some embodiments of this utility model, but not all embodiments.

[0027] The components of the present invention embodiments described and shown in the accompanying drawings can typically be arranged and designed in a variety of different configurations. Therefore, the following detailed description of the embodiments of the present invention provided in the drawings is not intended to limit the scope of the claimed invention, but merely to illustrate selected embodiments of the invention.

[0028] Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0029] In the description of this utility model, it should be noted that the terms "center," "upper," "lower," "left," "right," "vertical," "horizontal," "inner," and "outer," etc., indicating the orientation or positional relationship, are based on the orientation or positional relationship shown in the accompanying drawings and are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this utility model. Furthermore, the terms "first," "second," and "third" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0030] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0031] like Figure 1-4 As shown, the fatigue resistance testing device for the main lock of the carabiner 4 of this utility model includes a side plate 1 and a lifting mechanism 2. The left and right ends of the front side of the side plate 1 are fixedly installed with clamps 3. The carabiner 4 is clamped between the two clamps 3. A rotating part 5 is provided on the upper side of the carabiner 4. A pressure ring 6 is sleeved on the outer side of the rotating part 5.

[0032] The front side of the lower pressure ring 6 is formed with a lower pressure edge 7, and the bottom side of the lifting mechanism 2 is connected to a lower pressure rod 8. The lower pressure rod 8 presses on the lower pressure edge 7 and the lower pressure ring 6, driving the rotating part 5 to rotate and press.

[0033] The principle is as follows: First, the carabiner 4 to be tested is clamped firmly by the clamps 3 on both sides. Since the rotating part 5 of the carabiner 4 needs to be rotated before it can be pressed open, the lifting mechanism 2 is used to drive the pressing rod 8 to move up and down continuously. The pressing rod 8 will press on the pressing ring 6 and the pressing edge 7 to drive the rotating part 5 to rotate. After rotating to the correct position, it can be pressed. The rotating part 5 of the carabiner 4 can be elastically reset after rotation and pressing, which can realize the effect of continuous rotation and pressing test of the carabiner 4, thereby ensuring the fatigue strength of the main lock of the carabiner 4.

[0034] Furthermore: the middle part of the pressing rod 8 is formed with a right-angled side 9, which is located above the pressing ring 6. The bottom end of the pressing rod 8 presses on the pressing ring 6, driving the rotating part 5 to rotate. The right-angled side 9 presses on the pressing ring 6, driving the rotating part 5 to press. After pressing down the pressing ring 6, the pressing rod 8 can drive the rotating part 5 to rotate. After the rotating part 5 rotates to the position, the right-angled side 9 will directly press on the pressing ring 6, and then continue to drive the rotating part 5 to press, thereby realizing the automated cycle of rotation and pressing, and realizing the fatigue resistance test of the carabiner 4.

[0035] Furthermore: the front side of the side plate 1 is fixedly installed with a positioning bottom edge 10 by screws, and both clamps 3 are set above the positioning bottom edge 10, with the bottom side of the carabiner 4 placed on the positioning bottom edge 10; this facilitates the assembly of the carabiner 4 within the clamps 3.

[0036] Furthermore, the two clamps 3 are arranged symmetrically to each other, which can ensure the stable clamping of the carabiner 4.

[0037] Furthermore, the clamp 3 includes a first clamping plate 31, a second clamping plate 32, and a locking bolt 33. The locking bolt 33 passes through the second clamping plate 32 and the first clamping plate 31 in sequence and locks onto the side plate 1. The carabiner 4 is clamped and fixedly installed between the first clamping plate 31 and the second clamping plate 32. The distance between the first clamping plate 31 and the second clamping plate 32 can be adjusted by the locking bolt 33, thus making it suitable for fatigue resistance testing of carabiners 4 of different sizes and convenient for practical use.

[0038] Furthermore, the clamp 3 has at least two locking bolts 33, which makes the clamping of the carabiner 4 more secure.

[0039] Furthermore, a clearance groove 11 is formed in the middle of the front side of the side plate 1, and the lower pressure ring 6 is disposed in the clearance groove 11 with a clearance fit; this can avoid the rotating lower pressure ring 6, making the test more stable.

[0040] Furthermore: the lower pressure ring 6 is formed with screw holes 12, and a positioning bolt 13 is screwed into the screw holes 12. The inner end of the positioning bolt 13 presses against the outer side of the rotating part 5 for installation and locking; it can be applied to rotating parts 5 of different diameters for installation and testing.

[0041] Furthermore, the lower pressing edge 7 and the screw hole 12 are spaced apart vertically to prevent interference between the lower pressing rod 8 and the positioning bolt 13.

[0042] This embodiment does not impose any limitation on the shape, material, structure, etc. of this utility model. Any simple modifications, equivalent changes, and alterations made to the above embodiments based on the technical essence of this utility model shall fall within the protection scope of this utility model.
