Description

Technical Field

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

[0002] In our daily lives, retractable buckles are frequently used in accessories such as backpacks, briefcases, keychains, pet leashes, and fishing gear. A retractable buckle consists of a main body, a connector, and a retractable cord connecting the main body and the connector. If applied to a keychain, the main body is typically attached to a belt or waistband. The connector is magnetically attached to the main body. Items (such as keys) are hung on the connector. To use the item (e.g., keys), simply remove the connector and extend the retractable cord to detach the connector from the main body, making it easy to access the item (e.g., to open a door with a key). After use, the retractable cord is retracted, and the connector is magnetically attached to the corresponding position on the main body.

[0003] However, existing telescopic buckles typically rely solely on magnetic attraction between the buckle body and the connector. When heavy items are suspended from the connector, the connector can easily detach from the buckle body, making the structural design unreliable and posing a safety hazard. Furthermore, the lack of a locking mechanism between the existing buckle body and the connector means that the magnetic attraction alone cannot support heavy items, making it easy for the magnetic connection to break unexpectedly. Utility Model Content

[0004] The purpose of this invention is to provide a telescopic buckle magnetic connection structure, which aims to solve the technical problem of poor reliability in the existing structural design.

[0005] To achieve the above objectives, the present invention provides a telescopic snap-on magnetic connection structure, comprising:

[0006] The main body is provided with a connecting post, and a telescopic rope is telescopically provided inside the main body;

[0007] The connector is detachably magnetically connected to the connecting post. The end of the telescopic rope passes through the connecting post and is connected to the connector. The outer surface of the connector is provided with a locking groove.

[0008] A locking assembly includes a sliding sleeve, an elastic element, and a locking ring. The sliding sleeve is slidably fitted onto the connecting post along the axial direction, and a limiting structure is provided between the sliding sleeve and the connecting post to prevent the sliding sleeve from sliding off the connecting post. A through groove is formed on the side wall of the sliding sleeve, and the locking ring is slidably inserted into the through groove. The elastic element is disposed between the locking ring and the side wall of the sliding sleeve, so that when the sliding sleeve is slidably fitted onto the connector, the locking ring is engaged in the locking groove, thereby keeping the sliding sleeve and the connector axially locked. The locking ring can be disengaged from the locking groove by pushing and pressing the locking ring to slide and compressing the elastic element.

[0009] Furthermore, the locking ring includes a ring body and an abutment plate, the plane of the ring body is set at an angle to the plane of the abutment plate, and the elastic element is disposed between the abutment plate and the outer wall of the sliding sleeve.

[0010] Furthermore, the outer wall of the sliding sleeve is provided with a receiving groove, and one end of the elastic element is accommodated in the receiving groove.

[0011] Furthermore, the locking ring has a strip groove that extends along the sliding direction of the locking ring. A positioning element is provided in the through groove and passes through the strip groove to restrict the locking ring from disengaging from the through groove by cooperating with the strip groove.

[0012] Furthermore, the positioning element is a positioning post, and the lower end of the sliding sleeve is provided with a positioning hole along the vertical direction. The positioning hole is connected to the through groove so that the positioning post is inserted into the positioning hole and extends into the through groove. The opposite side walls of the sliding sleeve are both through-connected to form the through groove.

[0013] Furthermore, a first cavity is formed inside the connecting post, and a first ferromagnetic component is disposed inside the first cavity. A second cavity is formed at the upper end of the connector, and a second ferromagnetic component is disposed inside the second cavity, so that the connector and the connecting post are magnetically connected by the magnetic attraction between the first ferromagnetic component and the second ferromagnetic component.

[0014] Furthermore, the limiting structure includes a first limiting step and a second limiting step. The first limiting step is disposed on the inner circumferential surface of the sliding sleeve, and the second limiting step is disposed on the outer circumferential surface of the connecting post. The sliding sleeve is restricted from sliding off the connecting post by the first limiting step and the second limiting step abutting against each other. A connecting hole is provided on the connecting head.

[0015] Furthermore, by sliding the sliding sleeve upward relative to the engaging post until the locking ring is fitted onto the engaging post, the edge of the center hole of the locking ring abuts against the second limiting step of the engaging post.

[0016] Furthermore, the first ferromagnetic component has a first through hole in the vertical direction, and the second ferromagnetic component has a second through hole in the vertical direction, so that the end of the telescopic rope passes through the first through hole and the second through hole and is connected to the connector.

[0017] Furthermore, positioning notches are provided on both opposite side walls of the sliding sleeve, so that the lower part of the main body can be inserted into the positioning notches to position the sliding sleeve.

[0018] As can be seen from the above technical solution, the telescopic buckle magnetic connection structure of this utility model has a magnetic connection between the connector head and the connecting post of the main body. The connector head and the telescopic buckle main body are kept relatively locked by the locking component to prevent the connector head from accidentally detaching from the telescopic buckle main body. Specifically, the locking ring is slidably inserted into the through groove of the sliding sleeve. When the sliding sleeve is slidably fitted onto the connector head, the locking ring is locked in the locking groove of the connector head, thereby keeping the sliding sleeve and the connector head axially locked. This avoids the accidental disconnection of the magnetic connection between the connector head and the connecting post, thereby improving the reliability and safety of the connection structure. Furthermore, by pushing and pressing the locking ring to slide and compress the elastic element, the locking ring can be disengaged from the locking groove. At this time, the connector head and the connecting post can be separated. Users can adjust the locking or unlocking state of the locking component according to actual needs. It is convenient to use and simple and quick to operate.

[0032] 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.

[0033] Please refer to the following: Figures 1 to 6This embodiment provides a telescopic buckle magnetic connection structure, including a main body 100, a telescopic rope 200, a connector 300, and a locking assembly 400. A connecting post 110 is provided on the main body 100. The telescopic rope 200 is telescopically disposed within the main body 100. 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 connects to the connector 300. A locking groove 310 is provided on the outer surface of the connector 300. The locking assembly 400 includes a sliding sleeve 410, an elastic element 420, and a locking ring 430. The sliding sleeve 410 is slidably sleeved on the connecting post 110 along the axial direction. A limiting structure is provided between the 0 and the connecting post 110 to prevent the sliding sleeve 410 from sliding off the connecting post 110. The side wall of the sliding sleeve 410 is provided with a through groove 411. The locking ring 430 is slidably inserted into the through groove 411. The elastic element 420 is provided between the locking ring 430 and the side wall of the sliding sleeve 410. When the sliding sleeve 410 is provided on the connector 300, the locking ring 430 is locked in the locking groove 310, thereby keeping the sliding sleeve 410 and the connector 300 axially locked. The locking ring 430 can be disengaged from the locking groove 310 by pushing and pressing the locking ring 430 to slide and compressing the elastic element 420.

[0034] As can be seen, in this embodiment, the telescopic buckle magnetic connection structure and the telescopic buckle itself are magnetically connected between the connector 300 and the engaging post 110 of the main body 100, and the locking assembly 400 keeps the connector 300 and the telescopic buckle main body 100 locked relative to each other to prevent the connector 300 from accidentally detaching from the telescopic buckle main body 100. Specifically, the locking ring 430 is slidably inserted into the through groove 411 of the sliding sleeve 410 so that when the sliding sleeve 410 is placed on the connector 300, it is locked onto the connector 300 by the locking ring 430. The locking groove 310 of the 00 keeps the sliding sleeve 410 and the connector 300 axially locked, thereby preventing the magnetic connection between the connector 300 and the engaging post 110 from accidentally breaking, thus improving the reliability and safety of the connection structure. Furthermore, by pushing and pressing the locking ring 430 to slide and compress the elastic element 420, the locking ring 430 can be disengaged from the locking groove 310, at which point the connector 300 and the engaging post 110 can be separated. Users can adjust the locking or unlocking state of the locking component 400 according to actual needs, which is convenient to use and simple and quick to operate.

[0035] The telescopic rope 200 inside the main body 100 is wound and released by a spring reel. Its specific structure is existing technology and will not be described in detail here.

[0036] In this embodiment, the locking ring 430 includes a ring body 431 and an abutment plate 432. The plane of the ring body 431 is set at an angle to the plane of the abutment plate 432. An elastic element 420 is disposed between the abutment plate 432 and the outer side wall of the sliding sleeve 410. The elastic element 420 is pre-selected as a compression spring. One end of the ring body 431 is bent and extended to form the abutment plate 432, and the plane of the ring body 431 is approximately perpendicular to the plane of the abutment plate 432.

[0037] Specifically, the outer wall of the sliding sleeve 410 is provided with a receiving groove 412, and one end of the elastic member 420 is accommodated in the receiving groove 412. By pressing the abutment plate 432 to slide and compress the elastic member 420, the edge of the central hole of the ring 431 is disengaged from the locking groove 310. At this time, the sliding sleeve 410 is slid upward relative to the engaging post 110 until the central hole of the ring 431 is fitted onto the engaging post 110, and the edge of the central hole of the ring 431 abuts against the second limiting step 111 of the engaging post 110. Figure 6 As shown, this allows the connector 300 to be switched to a magnetic connection with the engagement post 110, which can be used in various scenarios. This makes it easy for users to switch the connection method according to their needs. When the locking component 400 is unlocked, the connector 300 can be pulled out from the central hole of the ring 431. The locking groove 310 is an annular groove extending along the outer peripheral surface of the connector 300.

[0038] Furthermore, a strip groove 433 is provided on the locking ring 430. The strip groove 433 extends along the sliding direction of the locking ring 430. A positioning element is provided in the through groove 411. The positioning element passes through the strip groove 433 so as to restrict the locking ring 430 from disengaging from the through groove 411 by cooperating with the strip groove 433.

[0039] Furthermore, the positioning element is a positioning pin 414, and the lower end of the sliding sleeve 410 is provided with a positioning hole 413 along the vertical direction. The positioning hole 413 is connected to the through groove 411 so that the positioning pin 414 is inserted into the positioning hole 413 and extends into the through groove 411. The opposite side walls of the sliding sleeve 410 are both provided to form the through groove 411.

[0040] In this embodiment, a first cavity is provided in the connecting post 110, and a first ferromagnetic component 112 is provided in the first cavity. A second cavity is provided at the upper end of the connector 300, and a second ferromagnetic component 330 is provided in the second cavity. The connector 300 and the connecting post 110 are magnetically connected by the magnetic attraction between the first ferromagnetic component 112 and the second ferromagnetic component 330.

[0041] 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 112 and the second ferromagnetic component 330 and is connected to the connector 300.

[0042] Furthermore, the limiting structure includes a first limiting step 415 and a second limiting step 111. The first limiting step 415 is disposed on the inner circumferential surface of the sliding sleeve 410, and the second limiting step 111 is disposed on the outer circumferential surface of the connecting post 110. The sliding sleeve 410 is restricted from sliding off the connecting post 110 by the first limiting step 415 and the second limiting step 111 abutting against each other. The connector 300 is provided with a connecting hole 320 so that an item can be suspended on the connector 300 through the connecting hole 320.

[0043] In this embodiment, positioning notches are provided on both opposite side walls of the sliding sleeve 410 so that the lower part of the main body 100 can be inserted into the positioning notches to position the sliding sleeve 410. This allows the sliding sleeve 410 to slide only vertically on the connecting post 110 and not to rotate relative to the connecting post 110, thereby improving the stability and reliability of the structure.

[0044] As can be seen from the above description, the embodiments of this utility model achieve the following technical effects:

[0045] The telescopic buckle magnetic connection structure of this utility model magnetically connects the connector 300 to the engaging post 110 of the main body 100, and the locking assembly 400 keeps the connector 300 and the telescopic buckle main body 100 locked together to prevent the connector 300 from accidentally detaching from the telescopic buckle main body 100. Specifically, the locking ring 430 is slidably inserted into the through groove 411 of the sliding sleeve 410, so that when the sliding sleeve 410 is placed on the connector 300, the locking ring 430 is engaged with the locking groove of the connector 300. The sliding sleeve 410 is axially locked to the connector 300, thus preventing the magnetic connection between the connector 300 and the engaging post 110 from accidentally breaking, thereby improving the reliability and safety of the connection structure. Furthermore, by pushing and pressing the locking ring 430 to slide and compress the elastic element 420, the locking ring 430 can be disengaged from the locking groove 310, at which point the connector 300 and the engaging post 110 can be separated. Users can adjust the locking or unlocking state of the locking component 400 according to actual needs, making it convenient to use and easy and quick to operate.
