Description

Technical Field

[0001] This utility model relates to the field of locking technology, specifically to a twisted safety lock. Background Technology

[0002] Safety precautions are necessary in outdoor sports, fitness activities, and pet activities. Typically, a webbing is attached to the body for safety, and one end of the webbing usually needs a locking buckle to connect it to the body. This buckle is called a safety lock or climbing hook.

[0003] In addition, climbing hooks also play an important role in high-altitude operations, rock climbing, and fire descent equipment. They mainly serve as a connection between the descender and the operator. After the operation or work is completed, the climbing hook needs to be opened and removed from the descender to ensure safety at high altitudes or in rock climbing.

[0004] As existing technology, Chinese utility model patent CN213332011U specifically discloses a climbing carabiner. This carabiner features a rotating sleeve that, when rotated, exposes a locking groove, allowing the locking block to disengage. When the operator releases the rotating sleeve, it automatically returns to its original position, locking the locking block back into the groove. This type of carabiner adds a self-locking function, eliminating the need for manual return by the operator, making it more convenient, practical, and safer. However, this climbing carabiner structure still uses a single working surface to place ropes and other items, which has significant shortcomings when performing multi-device load operations. On the one hand, its load-bearing capacity is relatively weak, easily leading to increased safety hazards; on the other hand, when multiple pieces of equipment are on the same working surface, tangling is very likely to occur, significantly increasing the danger and resulting in poor practicality. Summary of the Invention

[0005] In view of the shortcomings of existing rock climbing carabiner solutions in terms of safety and reliability, the purpose of this utility model is to provide a highly reliable twisted safety lock. This twisted safety lock has high overall strength and strong operability, reduces the occurrence of knotting, and thus can effectively improve the reliability of the twisted safety lock.

[0006] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0007] A twisted safety lock includes a latch and a lower latch hook fixedly installed below the latch. A connecting rod is fixedly installed at the other end of the lower latch hook away from the latch. An upper latch hook is fixedly installed at the other end of the connecting rod away from the lower latch hook. A fixing rod is fixedly installed at the other end of the upper latch hook away from the connecting rod. A rotating rod is rotatably installed on the inner side of the extension of the fixing rod. A latch rod is fixedly installed at both ends of the rotating rod outside the extension of the fixing rod. A groove is formed at one end of the latch rod located on the fixing rod. The lower latch hook, the connecting rod, and the upper latch hook are an integral structure.

[0008] Preferably, the buckle is provided with a limiting component on the inner surface of the groove. The limiting component includes a limiting sleeve fixedly installed on the inner surface of the groove. The inner surface of the limiting sleeve is provided with slots on the left and right sides near the buckle. The limiting sleeve is fitted with a locking block and a limiting block through the slots. The other end of the limiting block away from the buckle abuts against the fixing rod. The diameter of the limiting component is the same as the radius of the buckle.

[0009] Through the above technical solution, by cooperating with the limiting block and the fixing rod, when the buckle is rotated, it can only rotate inward. The limiting block can limit the fixing rod, thereby preventing the buckle from rotating outward. This can prevent the buckle from rotating away from the connecting bend rod due to improper operation or accidental contact by the user. At the same time, due to its radius design, it will not affect its normal rotation.

[0010] Preferably, the limiting block and the card block are an integral structure, and the card slot is adapted to the card block.

[0011] The above technical solution, by integrating the limiting block and the locking block into a single structure, enhances the overall strength. Furthermore, the cooperation between the locking slot and the locking block can quickly limit the movement during production, preventing misalignment during subsequent welding and thus ensuring production quality.

[0012] Preferably, the lower hook and the upper hook have a "C" shaped cross-section, and the center plane of the lower hook forms an angle with the center plane of the connecting bend rod. The angle between the center plane of the lower hook and the center plane of the connecting bend rod is 5° to 30°.

[0013] The above technical solution, through the design of the "C"-shaped lower and upper hooks, increases the strength of the lower and upper hooks, enabling them to better withstand external forces and reduce the risk of deformation or damage due to excessive force. This allows multiple pieces of equipment to be loaded and operated simultaneously. Furthermore, the special angle design ensures that the working surface of the overall safety lock is not restricted, making it more practical compared to the single working surface of traditional safety locks.

[0014] Preferably, the center plane of the connecting bend rod forms an angle with the center plane of the upper hook, and the angle between the center plane of the connecting bend rod and the center plane of the upper hook is 5° to 30°.

[0015] By using the above technical solution and designing the angle between the center plane of the connecting bend and the center plane of the upper hook, when multiple pieces of equipment are working simultaneously, not only can the equipment be placed on different planes, but also the equipment can be prevented from getting tangled, thereby reducing safety hazards.

[0016] Preferably, the extension portion of the buckle located at one end of the connecting sleeve is fixedly installed with a locking tongue adapted to the buckle, and the fixing rod is rotatably installed with the buckle via a rotating rod.

[0017] Through the above technical solution, the locking tongue and the latch are matched to ensure the security lock is secure in the locked state and is not easily opened by external force, thus improving security. The fixed rod is installed by rotating the rod and the latch rod, making the operation more flexible and convenient. Users can easily rotate the latch rod to the appropriate position for locking and unlocking operations, which can adapt to different usage scenarios and angles, thus improving the versatility of the security lock.

[0018] Preferably, the other end of the buckle away from the fixing rod is threadedly connected to a connecting sleeve, and the outer surface of the connecting sleeve has multiple anti-slip patterns that are equidistantly distributed in a ring around the connecting sleeve.

[0019] Through the above technical solution, the threaded connection sleeve can be installed and disassembled as needed, increasing the adjustability of the safety lock and making it suitable for locked items of different sizes. The anti-slip texture on the outer surface of the connection sleeve can increase the friction between the hand and the lever, preventing the hand from slipping during operation and improving the stability and safety of operation. The annularly distributed anti-slip texture makes the anti-slip effect more uniform, and it can play a good anti-slip role no matter which angle you hold the lever from.

[0020] Compared with the prior art, the torsion safety lock solution provided by this utility model has the following advantages:

[0021] 1. This twisted safety lock, through the design of the "C"-shaped lower and upper hooks, increases the strength of the lower and upper hooks, enabling them to better withstand external forces and reducing the risk of deformation or damage due to excessive force. This allows multiple pieces of equipment to be loaded and operated simultaneously. Furthermore, the special angle design ensures that the working surface of the overall safety lock is not restricted, making it more practical compared to the single working surface of traditional safety locks. By designing the angle between the center plane of the connecting bend and the center plane of the upper hook, when multiple pieces of equipment are operating simultaneously, not only can they be placed on different planes, but it can also prevent the equipment from getting tangled, thereby reducing safety hazards.

[0022] 2. This twisted safety lock, through the cooperation of the limiting block and the fixed rod, can only rotate inward when the lever is rotated. The limiting block can limit the fixed rod, thereby preventing the lever from rotating outward. This can prevent the lever from rotating away from the connecting bent rod due to improper operation or accidental contact by the user. At the same time, due to its radius design, it will not affect its normal rotation. Attached Figure Description

[0030] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0031] Example 1:

[0032] See Figure 1 and Figure 2 The above is only a structural example of a twisted safety lock given in this example.

[0033] Based on the illustration, the twisted safety lock shown in this example mainly includes a latch 1 and a lower latch hook 2 fixedly installed under the latch 1.

[0034] Among them, the other end of the hook 2 away from the lock 1 is fixedly installed with a connecting bent rod 3, the other end of the connecting bent rod 3 away from the lower hook 2 is fixedly installed with an upper hook 4, the other end of the upper hook 4 away from the connecting bent rod 3 is fixedly installed with a fixing rod 5, a rotating rod 6 is rotatably installed on the inner side of the extension of the fixing rod 5, and hook rods 7 are fixedly installed at both ends of the rotating rod 6 outside the extension of the fixing rod 5. A groove 11 is opened at one end of the hook rod 7 located on the fixing rod 5. The lower hook 2, the connecting bent rod 3 and the upper hook 4 are an integral structure.

[0035] See further Figure 3 , Figure 4 as well as Figure 6 In some embodiments of this example, a limiting component 12 is provided on the inner surface of the buckle 7 located in the groove 11. The limiting component 12 includes a limiting sleeve 1201 fixedly installed on the inner surface of the groove 11. The inner surface of the limiting sleeve 1201 is provided with slots 1202 on the left and right sides near the buckle 7. The limiting sleeve 1201 is inserted and installed with a locking block 1203 and a limiting block 1204 through the slots 1202. The other end of the limiting block 1204 away from the buckle 1 abuts against the fixing rod 5. The diameter of the limiting component 12 is the same as the radius of the buckle 7.

[0036] With this configuration, through the cooperation of the limiting block 1204 and the fixing rod 5, when the buckle 7 rotates, it can only rotate inward. The limiting block 1204 can limit the fixing rod 5, thereby preventing the buckle 7 from rotating outward. This can prevent the buckle 7 from rotating away from the connecting bent rod 3 due to improper operation or accidental contact by the user. At the same time, due to its radius design, it will not affect its normal rotation.

[0037] Based on the above solution, in this example, the limiting block 1204 and the locking block 1203 are further designed as an integrated structure, with the locking slot 1202 compatible with the locking block 1203. By making the limiting block 1204 and the locking block 1203 an integrated structure, the overall strength is enhanced. Furthermore, the cooperation between the locking slot 1202 and the locking block 1203 allows for rapid positioning during production, preventing misalignment during subsequent welding and thus ensuring production quality.

[0038] See further Figure 3 and Figure 4 In some embodiments of this example, the lower hook 2 and the upper hook 4 are configured with a "C"-shaped cross-section. The center plane of the lower hook 2 forms an angle with the center plane of the connecting bent rod 3, and the angle between the center plane of the lower hook 2 and the center plane of the connecting bent rod 3 is 5° to 30°.

[0039] This design, through the "C"-shaped lower hook 2 and upper hook 4, effectively increases the strength of the lower hook 2 and upper hook 4, enabling them to better withstand external forces and reduce the risk of deformation or damage due to excessive force. This allows multiple pieces of equipment to be loaded and operated simultaneously. Furthermore, the special angle design ensures that the working surface of the overall safety lock is not restricted, making it more practical compared to the single working surface of traditional safety locks.

[0040] Example 2:

[0041] This example provides a further specific optimization scheme based on the scheme in Example 1.

[0042] See Figures 1 to 4 As shown, in this example, the center plane of the connecting bend rod 3 and the center plane of the upper hook 4 are set to form an angle, and the angle between the center plane of the connecting bend rod 3 and the center plane of the upper hook 4 is 5° to 30°.

[0043] This example demonstrates how the design of the angle between the center plane of the connecting rod 3 and the center plane of the upper hook 4 can ensure that multiple pieces of equipment are on different planes when multiple pieces of equipment are working simultaneously, while also preventing them from getting tangled, thus reducing safety hazards.

[0044] See further Figure 3 and Figure 4 In this example, a locking tongue 10 adapted to the latch 1 is fixedly installed on the extension of the latch 7 at one end of the connecting sleeve 8, and the fixing rod 5 is rotatably installed with the latch 7 via the rotating rod 6.

[0045] This design allows the latch 10 to be matched with the latch 1, ensuring the safety lock's stability in the locked state and making it difficult to be opened by external force, thus improving security. The fixing rod 5 is rotated and installed with the latch rod 7 via the rotating rod 6, making operation more flexible and convenient. Users can easily rotate the latch rod 7 to the appropriate position for locking and unlocking operations, adapting to different usage scenarios and angles, thus improving the versatility of the safety lock.

[0046] See further Figure 5 In this example, a connecting sleeve 8 is threaded to the other end of the buckle 7 away from the fixing rod 5. Multiple anti-slip patterns 9 are provided on the outer surface of the connecting sleeve 8 in a ring-shaped and equidistant pattern.

[0047] The threaded connection sleeve 8 can be installed and removed as needed, increasing the adjustability of the safety lock and making it suitable for locked items of different sizes. The anti-slip texture 9 on the outer surface of the sleeve 8 increases the friction between the hand and the lever 7, preventing the hand from slipping during operation and improving the stability and safety of operation. The annularly distributed anti-slip texture 9 makes the anti-slip effect more uniform, and it can play a good anti-slip role no matter which angle you hold the lever 7 from.

[0048] The following section, in conjunction with the accompanying drawings, further explains the operation of the twisted safety lock described in the above example scheme.

[0049] See Figures 1 to 6 When this twisted safety lock is in use, the limiting block 1204 cooperates with the fixed rod 5 so that when the latch 7 is rotated, it can only rotate inward. The limiting block 1204 can limit the fixed rod 5, thereby preventing the latch 7 from rotating outward. This can prevent the latch 7 from rotating away from the connecting bent rod 3 due to improper operation or accidental contact by the user. At the same time, due to its radius design, it will not affect its normal rotation.

[0050] Meanwhile, the integrated structure of the limiting block 1204 and the locking block 1203 enhances the overall strength. Furthermore, the cooperation between the locking slot 1202 and the locking block 1203 can quickly limit the movement during production, preventing misalignment during subsequent welding and thus affecting production quality.

[0051] Based on the "C"-shaped lower hook 2 and upper hook 4, the strength of the lower hook 2 and upper hook 4 is increased, enabling them to better withstand external forces and reduce the risk of deformation or damage due to excessive force. This allows multiple pieces of equipment to be loaded and operated simultaneously. Furthermore, through a special angle design, the working surface of the overall safety lock is not restricted, making it more practical compared to the single working surface of traditional safety locks.

[0052] Furthermore, based on the angle between the center plane of the connecting bend rod 3 and the center plane of the upper hook 4, when multiple pieces of equipment are working simultaneously, not only can the equipment be placed on different planes, but it can also prevent the equipment from getting tangled, thereby reducing safety hazards. The locking tongue 10 is compatible with the locking buckle 1, which can ensure the firmness of the safety lock in the locked state and make it difficult to be opened by external force, thus improving safety. The fixing rod 5 is rotated and installed with the buckle 7 through the rotating rod 6, making the operation more flexible and convenient. Users can easily rotate the buckle 7 to the appropriate position for locking and unlocking operations, which can adapt to different usage scenarios and angles, thus improving the versatility of the safety lock.

[0053] Furthermore, the threaded connecting sleeve 8 can be installed and removed as needed, increasing the adjustability of the safety lock and making it suitable for locked items of different sizes. The anti-slip texture 9 on the outer surface of the connecting sleeve 8 can increase the friction between the hand and the lever 7, preventing the hand from slipping during operation and improving the stability and safety of operation. The annularly distributed anti-slip texture 9 makes the anti-slip effect more uniform, and it can play a good anti-slip role no matter which angle you hold the lever 7 from.

[0054] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
