Description

Technical Field

[0001] This utility model relates to the field of telescopic buckle technology, and in particular to a novel telescopic buckle. Background Technology

[0002] Currently, telescopic buckles mainly consist of a buckle body and a hanging ring. The hanging ring is generally used to hang on the buckle body of pants. The hanging ring and the buckle body are connected by a telescopic rope. Items (such as keys) are hung on the hanging ring. When you need to use the hung item (such as keys), simply remove the hanging ring from the buckle body, extend the telescopic rope, and then use the item on the hanging ring (such as using a key to open a door). After using the item, the spring roller inside the buckle body will automatically rewind the telescopic rope, and then the hanging ring can be hung back on the buckle body.

[0003] During use, due to the elastic winding action of the spring reel, every time a small section of the retractable cord is loosened between the item and the buckle body, the spring reel will wind up the excess cord. Existing retractable buckles generally lack a locking mechanism for the extended cord, leaving the cord constantly taut. This makes it inconvenient to use items freely for extended periods. Furthermore, to facilitate quick and easy access to items, existing retractable buckles typically use magnets to attach the loop to the buckle body, again lacking a locking mechanism for the cord's retracted state. As the magnetic force gradually weakens, the loop's load-bearing capacity becomes very low. Moreover, the torque increases with the movement of the user and the swinging of the item, making it easy for the item to fall off. Once fallen, the cord remains attached, posing a significant safety hazard, whether cycling, outdoor sports, or work, as the cord becomes entangled, tripping, or getting caught in wheels, potentially leading to accidents. Utility Model Content

[0004] The purpose of this utility model is to provide a new type of telescopic buckle, which aims to solve at least one of the technical problems existing in the prior art.

[0005] To achieve the above objectives, the present invention provides a novel telescopic buckle, comprising:

[0006] The main body is provided with a connecting post;

[0007] A connector that can be detachably engaged with the engagement post;

[0008] A reel, rotatably disposed within the main body, is used for winding and releasing a telescopic rope, the end of which passes through the connecting post and is connected to the connector.

[0009] A coil spring, the two ends of which are respectively connected to the spool and the main body, the coil spring being used to apply a force to the spool to rotate in the direction of winding the telescopic rope;

[0010] A ratchet, which is fixed to one side of the spool and has multiple protrusions spaced apart circumferentially;

[0011] A locking element, movably disposed within the main body, wherein the locking pawl of the locking element is correspondingly disposed with respect to the ratchet; and

[0012] A sliding member is slidably disposed within the main body, and one end of the sliding member protrudes from the inner wall of the main body to form a push key, so as to drive the sliding member to slide through the push key and push the locking member to rotate until the locking claw abuts against the protrusion, thereby restricting the rotation of the spool in the direction of winding or releasing the telescopic rope.

[0013] Furthermore, it also includes a torsion spring disposed within the main body, and the locking member is provided with an abutting end, with the two ends of the torsion spring respectively connected to the abutting end and the inner wall of the main body.

[0014] Furthermore, one end of the slider extends upward to form a top abutment, and the locking member is located above the slider so as to push the locking claw against the protrusion through the top abutment. The side wall of the main body is provided with a sliding groove along the transverse direction, and the push key is slidably disposed in the sliding groove.

[0015] Furthermore, the main body includes a shell, a left cover plate, and a right cover plate. The left cover plate and the right cover plate are respectively installed on the left and right sides of the shell. A first installation space is provided between the left cover plate and the shell, and a second installation space is provided between the right cover plate and the shell. A through hole is provided on the shell so that the first installation space and the second installation space can be connected through the through hole. A central shaft is provided on the left cover plate. The central shaft is inserted into the second installation space through the through hole. The reel is rotatably mounted on the central shaft and is housed in the second installation space.

[0016] Furthermore, the ratchet, locking member, and sliding member are all installed within the first mounting space, and the coil spring is housed within the spool, with one end of the coil spring inserted into the central shaft and the other end inserted into the inner wall of the spool.

[0017] Furthermore, a mounting post is provided in the first mounting space of the main body, the torsion spring is sleeved on the mounting post, and the torsion spring is located on the side of the abutment end away from the ratchet.

[0018] Furthermore, the locking element is rotatably disposed within the main body, and the locking element is generally T-shaped.

[0019] Furthermore, the lower end of the connecting post is provided with a first cavity, and a first ferromagnetic component is disposed in the first cavity. The upper end of the connector is provided with a second cavity, and a second ferromagnetic component is disposed in the second cavity, so that the connector and the connecting post can be magnetically connected in a separable manner through the magnetic attraction between the first ferromagnetic component and the second ferromagnetic component.

[0020] Furthermore, the upper end of the connecting post is threadedly connected to the main body, and the interior of the connecting post is a hollow structure. The end of the telescopic rope passes through the connecting post, the first ferromagnetic component, and the second ferromagnetic component and is connected to the connector.

[0021] Furthermore, the connector has a connection hole.

[0022] As can be seen from the above technical solution, the novel telescopic buckle of this utility model has a ratchet fixed on one side of the spool, and a locking member is movably set in the main body. The locking member is in a locked or unlocked state relative to the ratchet. By pushing the key, the sliding member is driven to slide and push the locking member to rotate until the locking claw abuts against the protrusion, thereby restricting the spool from rotating in the direction of winding or releasing the telescopic rope. When the ratchet is in the locked state, the spool is locked and cannot rotate to wind the telescopic rope. In this way, the telescopic rope will not be kept in a taut state when it is stretched, so that the items hanging on the connector can be used freely for a long time. Or, when the ratchet is in the locked state, the spool is locked and cannot rotate to release the telescopic rope. In this way, even if the connector is detached from the main body of the telescopic buckle, the telescopic rope will be locked and kept in the wound state and will not be stretched, so as to avoid accidents caused by the telescopic rope getting tangled due to the connector falling off. This effectively improves the safety and reliability of the structural design. The state of the spool or ratchet can be freely adjusted and switched according to the user's needs, which is convenient for the user.

[0036] To enable those skilled in the art to better understand the technical solutions of this application, the technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this application, and not all of the embodiments. 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 application.

[0037] Please refer to the following: Figures 1 to 7This embodiment provides a novel telescopic buckle, including a main body 100, a connector 300, a spool 180, a coil spring 181, a ratchet 140, a locking member 150, and a sliding member 160. The main body 100 is provided with a connecting post 110. The connector 300 is detachably magnetically connected to the connecting post 110. The end of the telescopic rope 200 passes through the connecting post 110 and is connected to the connector 300. The spool 180 is rotatably disposed within the main body 100 and is used to wind and release the telescopic rope 200. The two ends of the coil spring 181 are respectively connected to the spool 180 and the main body 100. The coil spring 181 applies a force to the spool 180 to rotate in the direction of winding the telescopic rope 200. The ratchet 140 is fixed to the side of the spool 180 away from the coil spring 181. Furthermore, the ratchet 140 is provided with a plurality of protrusions 141 spaced apart circumferentially; the locking member 150 is movably disposed within the main body 100, and the locking claw 151 of the locking member 150 is correspondingly disposed with respect to the ratchet 140; the sliding member 160 is slidably disposed within the main body 100, and one end of the sliding member 160 protrudes from the inner wall of the main body 100 to form a push key 161, so that the sliding member 160 is driven to slide by the push key 161 and pushes the locking member 150 to rotate until the locking claw 151 abuts against the protrusions 141, thereby blocking the ratchet 140 from rotating, thereby restricting the spool 180 from rotating in the direction of winding or releasing the telescopic rope 200. In this way, the end of the telescopic rope 200 can be stopped at a preset length, making it convenient for the user to freely use the items suspended on the connector 300.

[0038] As can be seen, the novel telescopic buckle of this utility model has a ratchet 140 fixed to one side of the spool 180, and a locking member 150 movably disposed within the main body 100. The locking member 150 is in a locked or unlocked state relative to the ratchet 140. By pushing the key 161, the sliding member 160 is slid and the locking member 150 is pushed to rotate until the locking pawl 151 abuts against the protrusion 141, thereby restricting the rotation of the spool 180 in the direction of winding or releasing the telescopic rope 200. When the ratchet 140 is in the locked state, the spool 180 is locked and cannot rotate to wind the telescopic rope 200. In this way, the telescopic rope 200 can be wound. When stretched, it will not remain taut, allowing for extended use of items hung on the connector 300; or, when the ratchet 140 is locked, the reel 180 is locked and cannot rotate to release the telescopic rope 200. Thus, even if the connector 300 detaches from the telescopic buckle body 100, the telescopic rope 200 will remain locked in a wound state and will not be stretched, preventing accidents caused by the telescopic rope 200 becoming entangled due to the connector 300 detaching. This effectively improves the safety and reliability of the structural design. The state of the reel 180 or ratchet 140 can be freely adjusted and switched according to user needs for ease of use.

[0039] In this embodiment, the telescopic buckle also includes a torsion spring 170, which is disposed inside the main body 100, and the locking member 150 is provided with an abutment end 152. The two ends of the torsion spring 170 are respectively connected to the abutment end 152 and the inner wall of the main body 100, and the locking member 150 is generally T-shaped.

[0040] Specifically, the main body 100 includes a housing 120, a left cover plate 130, and a right cover plate 190. The left cover plate 130 and the right cover plate 190 are respectively installed on the left and right sides of the housing 120. A first installation space is provided between the left cover plate 130 and the housing 120, and a second installation space is provided between the right cover plate 190 and the housing 120. A through hole 121 is provided on the housing 120 to connect the first installation space and the second installation space. A central shaft 131 is provided on the left cover plate 130, and the central shaft 131 is inserted into the second installation space through the through hole 121. Inside the space, the spool 180 is housed in the second mounting space and is rotatably arranged around the central axis 131. The coil spring 181 is disposed inside the spool 180, with one end of the coil spring 181 inserted into the central axis 131 and the other end of the coil spring 181 inserted into the inner wall of the spool 180. The ratchet 140, locking member 150, sliding member 160 and torsion spring 170 are housed in the first mounting space, and the telescopic rope 200 on the spool 180 passes through the bottom of the second mounting space. The first mounting space is provided with a mounting post 171, and the torsion spring 170 is sleeved on the mounting post 171.

[0041] In this embodiment, a first cavity is provided in the connecting post 110, and a first ferromagnetic component is disposed in the first cavity. A second cavity is provided at the upper end of the connector 300, and a second ferromagnetic component is disposed in the second cavity, so that the connector 300 and the connecting post 110 are magnetically connected by the magnetic attraction between the first ferromagnetic component and the second ferromagnetic component.

[0042] Specifically, the upper end of the connecting post 110 is threaded to the main body 100, and the interior of the connecting post 110 is a hollow structure. The telescopic rope 200 passes through the connecting post 110, the first ferromagnetic component, and the second ferromagnetic component and is connected to the connector 300.

[0043] The connector 300 has a connection hole 320, through which an item can be hung.

[0044] Furthermore, one end of the slider 160 extends upward to form a top abutment 162, and the locking member 150 is located above the slider 160 so that the top abutment 162 pushes the locking claw 151 against the protrusion 141. The side wall of the main body 100 is provided with a sliding groove 132 in the transverse direction, and the push key 161 is slidably disposed in the sliding groove 132 so that the locking state or unlocking state between the locking member 150 and the ratchet 140 can be switched by sliding the push key 161.

[0045] As can be seen from the above description, the embodiments of this utility model achieve the following technical effects:

[0046] The novel telescopic buckle of this embodiment features a ratchet 140 fixed to one side of the reel 180, and a locking member 150 movably disposed within the main body 100. The locking member 150 is in a locked or unlocked state relative to the ratchet 140. By pushing the key 161, the sliding member 160 slides and the locking member 150 rotates until the locking pawl 151 abuts against the protrusion 141, thereby restricting the rotation of the reel 180 in the direction of winding or releasing the telescopic rope 200. When the ratchet 140 is locked, the reel 180 is locked and cannot rotate to wind the telescopic rope 200. Thus, when the telescopic rope 200 is stretched... It will not be in a taut state all the time, so that items hanging on the connector 300 can be used freely for a long time; or when the ratchet 140 is in the locked state, the spool 180 is locked and cannot be rotated to release the telescopic rope 200. In this way, even if the connector 300 is detached from the main body 100 of the telescopic buckle, the telescopic rope 200 will be locked and kept in the coiled state and will not be stretched, so as to avoid accidents caused by the telescopic rope 200 getting tangled due to the connector 300 falling off. This effectively improves the safety and reliability of the structural design. The state of the spool 180 or the ratchet 140 can be freely adjusted and switched according to the user's own needs, which is convenient for the user.
