Description

Technical Field

[0001] This utility model relates to a connecting device, particularly a connecting shackle, and especially a novel quick shackle. Background Technology

[0002] like Figure 1 As shown, a shackle (including shackle body 1, pin 2, nut 3, and cotter pin 4) is a commonly used connecting device in the machinery industry. It is mainly used to connect different objects, such as steel cables and slings, to achieve safe lifting and movement of loads. It is primarily used in hoisting and transportation, shipbuilding and marine engineering, and construction engineering, among other industries. Pin 2 is the key fixing component of the shackle, responsible for connecting the two parts of shackle body 1 together. Pin 2 is usually fixed to shackle body 1 by nut 3 and cotter pin 4. Another connection method is to machine a threaded thread at one end of the ring body, and directly screw the threaded end of pin 2 onto the threaded thread. Yet another connection method is to have a small hole at one end of pin 2, through which the cotter pin is inserted for fixing. These connection methods have disadvantages in some industries, such as inconvenient disassembly, low work efficiency, and the easy loss of scattered parts after disassembly. Furthermore, workers are prone to misalignment of the threads during operation, creating certain safety hazards.

[0003] Therefore, how to provide a shackle that can be operated with one hand and is easier and faster to install and disassemble is an urgent problem to be solved. Summary of the Invention

[0004] To address the shortcomings mentioned above, this utility model provides a novel quick-release buckle that allows for rapid assembly and disassembly of the pin assembly with one-handed operation, offering convenience and speed while improving work efficiency.

[0005] To achieve the above objectives, this utility model provides a novel quick-release buckle, comprising a buckle body and a pin assembly. The buckle body has corresponding through holes a and b. When in a locked state, the pin assembly is fixed inside the through holes a and b. The pin assembly includes a pin body, a toggle shaft, a tongue assembly, a transmission block, and a transmission shaft. The pin body includes a head located outside the first part of the buckle body, a tail located outside the second part of the buckle body, and a middle part located between the first and second parts. A portion of the toggle shaft is rotatably disposed inside the pin body. The tongue assembly is embedded inside the tail and surrounds the outside of the toggle shaft. The transmission block is disposed inside the tail and located behind the tongue assembly and sleeved on the outside of the toggle shaft. A slide is formed on the tongue assembly. The transmission shaft is disposed inside the tongue assembly and the transmission block, respectively. When the actuating shaft rotates to the first position, the tongue assembly extends to the outside of the tail. When the actuating shaft rotates to the second position, the tongue assembly retracts into the inside of the head.

[0006] In one embodiment, the shape of the longitudinal section of the actuating shaft is the same as the shape of the first through hole on the transmission block, and both are non-circular structures.

[0007] In one embodiment, a torsion spring is also included, which is embedded in and fixed in a slot on the front end face of the head.

[0008] In one embodiment, a retaining ring is also included, located on the rear side of the transmission block, with a portion of the retaining ring embedded inside the actuating shaft.

[0009] In one embodiment, a sealing nut is also included, which is embedded inside the tail section, located on the rear side of the transmission block, and sleeved on the outside of the actuating shaft.

[0010] In one embodiment, the tongue assembly includes a first tongue and a second tongue that are positioned correspondingly, both of which surround the outside of the actuating shaft. An arc-shaped first slide is formed on the first tongue, and a second slide is formed on the second tongue. One drive shaft is placed in the drive block and the first slide, and another drive shaft is placed in the drive block and the second slide. When the actuating shaft rotates to the first position, one of the drive shafts moves from the first position in the first slide to the second position, and a portion of the first tongue extends out to the outside of the tail. The other drive shaft moves from the first position in the second slide to the second position, and a portion of the second tongue extends out to the outside of the tail. When the actuating shaft rotates to the second position, one of the drive shafts moves from the second position in the first slide to the first position, and the first tongue retracts into the interior of the tail. The other drive shaft moves from the second position in the second slide to the first position, and the second tongue retracts into the interior of the tail.

[0011] In one embodiment, a first concave region is formed in a local area of ​​the rear end face of the first tongue, and a second concave region is formed in a local area of ​​the rear end face of the second tongue, wherein the first concave region and the second concave region respectively surround a first portion and a second portion of the actuating shaft.

[0012] In one embodiment, a first slot and a second slot with corresponding positions are provided on the side wall of the tail. The first tongue is embedded in the first slot and the second tongue is embedded in the second slot. When at least a portion of the first tongue is placed in the first slot, the first tongue forms a 90-degree angle with the actuating shaft. When at least a portion of the second tongue is placed in the second slot, the second tongue forms a 90-degree angle with the actuating shaft.

[0013] Compared with the prior art, the present invention has one of the following advantages: By rotating the actuating shaft, the tongue assembly can be moved between the first and second positions, making it easy to lock the pin assembly onto or remove it from the shackle body. The pin assembly can be quickly disassembled and assembled with one hand, which is convenient and quick, improves work efficiency, reduces safety hazards caused by improper operation by workers, and is applicable to a variety of scenarios.

Detailed Implementation

[0016] To make the objectives, technical solutions, and advantages of this utility model clearer, the technical solutions of this utility model will be clearly and completely described below in conjunction with specific embodiments and corresponding drawings. Obviously, the described embodiments are only a part of the embodiments of this utility model, and not all of them. 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.

[0017] Example 1.

[0018] like Figures 2 to 5 As shown, this embodiment provides a novel quick-release buckle, including a buckle body 1 and a pin assembly 5.

[0019] Specifically, the shackle body 1 includes corresponding first part 101 and second part 102. The first part 101 has a through hole a penetrating through it, and the second part 102 has a through hole b penetrating through it. The positions of through holes a and b correspond to each other and are on the same axis. When the shackle body 1 and the pin assembly 5 are in the locked state, the pin assembly 5 passes through the interiors of through holes a and through holes b in sequence, thereby fixing the pin assembly 5 to the first part 101 and the second part 102.

[0020] Specifically, the pin assembly 5 includes a pin body, a pusher shaft 504, a tongue assembly, a transmission block 508, a sealing nut 511, a transmission shaft 509, a retaining ring 510, and a torsion spring 505.

[0021] Furthermore, the pin body includes a head 501 located outside the first part 101 of the shackle body 1, a tail 503 located outside the second part 102 of the shackle body 1, and an intermediate part 502 located between the first part 101 and the second part 102. A central hole penetrating the pin body is located at its axial center. A groove 5031 is formed on the end face of the tail 503, with the end of the central hole communicating with the internal area of ​​the groove 5031. A retaining groove 5010 is formed on the front end face of the head 501, located on one side of the central hole.

[0022] The end of the torsion spring 505 is placed inside the slot 5010, and the front end of the torsion spring 505 is fixed in the slot 5010.

[0023] The actuating shaft 504 includes a horizontal portion that can be inserted into a central hole and a curved portion located outside the head 501, wherein the curved portion forms a handle 5040, and by rotating the handle 5040, the horizontal portion can be rotated inside the central hole.

[0024] Both the sealing nut 511 and the transmission block 508 are placed inside the groove 5031. A second through hole and a first through hole are formed at corresponding positions on the sealing nut 511 and the transmission block 508. When the sealing nut 511, the snap ring 510, and the transmission block 508 are sequentially placed inside the groove 5031, the central hole, the first through hole, and the second through hole are on the same axis. When the horizontal portion is placed inside the central hole, its end passes through the first and second through holes sequentially. Simultaneously, a portion of the snap ring 510 is also embedded inside the horizontal portion. When the snap ring 510 is embedded inside the horizontal portion, it prevents the actuating shaft 504 from being pulled out of the pin body. When the sealing nut 511 is placed inside the groove 5031, it seals the tail portion 503.

[0025] Furthermore, the shape of the longitudinal section of the horizontal part is the same as the shape of the longitudinal section of the first through hole, so that when the horizontal part rotates in the central hole, it can drive the transmission block 508 to rotate synchronously.

[0026] Optionally, the longitudinal cross-section of the actuating shaft 504 and the shape of the first through hole on the transmission block 508 are both non-circular structures. This design makes it easier for the actuating shaft 504 to drive the transmission block 508 to rotate.

[0027] In this embodiment, a first slot and a second slot with corresponding positions are formed on the side wall of the tail portion 503. The ends of the first slot and the second slot are both connected to the central hole, and the end of the first slot and the end of the second slot form a 90-degree angle with the central hole. The tongue assembly includes a first tongue 506 and a second tongue 507 with corresponding positions, and the transmission block 508 and the sealing nut 511 are located sequentially on the rear side of the first tongue 506 and the second tongue 507.

[0028] Furthermore, the first tongue 506 is placed inside the first slot, and the second tongue 507 is placed inside the second slot. Both the first tongue 506 and the second tongue 507 surround the outer side of the horizontal portion. A first concave region is formed in a localized area of ​​the rear end face of the first tongue 506, and a second concave region is formed in a localized area of ​​the rear end face of the second tongue 507. The first and second concave regions respectively surround the first and second portions of the horizontal portion. An arc-shaped first slide rail 5060 is formed on the first tongue 506, and a second slide rail 5070 is formed on the second tongue 507. One drive shaft 509 is placed in the drive block 508 and the first slide rail 5060, and another drive shaft 509 is placed in the drive block 508 and the second slide rail 5070.

[0029] Since the shape of the first through hole is the same as the shape of the horizontal part, when the transmission block 508 is sleeved and fastened to the outside of the horizontal part, the horizontal part drives the transmission block 508 to rotate, which in turn drives the first tongue 506 and the second tongue 507 to move through the two transmission shafts 509 respectively. When the actuating shaft 504 is in the first position, the first tongue 506 and the second tongue 507 are also in the first position (that is, the first tongue 506 and the second tongue 507 are located inside the first slot and the second slot respectively). The outer end face of the first tongue 506 and the outer wall face of the tail are on the same plane, and the outer end face of the second tongue 507 and the outer wall face of the tail are on the same plane. At this time, in the orthographic projection state, the first tongue 506 and the second tongue 507 are both located inside the through hole b. When the actuating shaft 504 rotates to the second position, the two transmission shafts 509 move in the first slide rail 5060 and the second slide rail 5070 respectively, so that a part of the first tongue 506 and a part of the second tongue 507 move to the outside of the first slot and the second slot respectively, and are simultaneously located in the second position. At this time, in the orthographic projection state, the first tongue 506 and the second tongue 507 are both located outside the through hole b.

[0030] In this embodiment, when the pin is placed inside through holes a and b, and it is necessary to fasten the pin to the shackle body 1, the actuating shaft 504 is rotated from the first position to the second position. The actuating shaft 504 drives the transmission block 508 to rotate. At this time, the two transmission shafts 509 move in the first slide rail 5060 and the second slide rail 5070 respectively, causing a part of the first tongue 506 to move from the inside of the first slot to the outside of the first slot, and a part of the second tongue 507 to move from the inside of the second slot to the outside of the second slot. Under the action of the first tongue 506 and the second tongue 507, the pin is fastened to the shackle body 1. At this time, the torsional force generated by the torsion spring keeps a part of the first tongue 506 and a part of the second tongue 507 in an extended state. When it is necessary to remove the pin from the shackle body 1, rotate the actuating shaft 504 from the second position to the first position. The actuating shaft 504 drives the transmission block 508 to rotate. At this time, the two rotating shafts 509 move in the first slide rail 5060 and the second slide rail 5070 respectively. A part of the first tongue 506 moves from the outside of the first slot to the inside of the first slot, and a part of the second tongue 507 moves from the outside of the second slot to the inside of the second slot. At this time, the pin can be removed from the shackle body 1.

[0031] The above description is merely a preferred embodiment of the present utility model and is illustrative rather than restrictive. Those skilled in the art will understand that many changes, modifications, and even equivalents can be made within the spirit and scope defined by the claims of the present utility model, all of which will fall within the protection scope of the present utility model.
