Description

Technical Field

[0001] This utility model relates to the field of quick-release connector technology, and in particular to a magnetic quick-release connector structure. Background Technology

[0002] In our daily lives, quick-release connectors are frequently used in accessories such as backpacks, briefcases, keychains, pet leashes, and fishing gear. For example, a keychain consists of a belt buckle and a loop. The belt buckle is typically used to secure the keychain to a belt or trousers. The loop and belt buckle are connected by a quick-release connector. Items (such as keys) are hung on the loop. When you need to use the item (such as keys), simply disconnect the quick-release connector to separate the loop from the belt buckle, making it easy to use the item on the loop (such as using a key to open a door). After using the item, quickly reassemble the quick-release connector between the loop and the belt buckle to hang the loop back on the belt buckle.

[0003] To facilitate quick access to keys, existing quick-release connection structures generally employ magnetic connections. However, relying solely on magnetic connections makes it easy for the loop to accidentally detach from the belt buckle when heavy items are suspended on the connector or loop. This design is unreliable and poses a safety hazard. Existing quick-release connection structures only have magnetic connections without a locking mechanism, meaning that the magnetic force alone cannot support heavy items, making it easy for the magnetic connection to break. Utility Model Content

[0004] The purpose of this invention is to provide a magnetic quick-release connection structure, which aims to solve the technical problem that the structural design in the prior art is not reliable enough.

[0005] To achieve the above objectives, the present invention provides a magnetic quick-release connection structure, comprising:

[0006] The main locking pin is generally columnar in shape, and a first connecting hole is provided at the upper end of the main locking pin along the horizontal direction.

[0007] The secondary locking pin has a second connecting hole at its lower end along the lateral direction. The upper end of the secondary locking pin is detachably magnetically connected to the lower end of the main locking pin, and an annular groove is formed on the outer surface of the secondary locking pin.

[0008] The locking assembly includes an outer sleeve, an elastic element, and a limiting ring. The outer sleeve is slidably fitted onto the main locking pin along the axial direction, and a limiting structure is provided between the outer sleeve and the main locking pin to prevent the outer sleeve from sliding off the main locking pin. A limiting groove is formed on the side wall of the outer sleeve, and the limiting ring is slidably disposed in the limiting groove. The elastic element is disposed between the limiting ring and the side wall of the outer sleeve, so that when the outer sleeve is slidably fitted onto the secondary locking pin, it is engaged in the annular groove by the limiting ring, thereby keeping the outer sleeve and the secondary locking pin axially locked. By pushing and pressing the limiting ring to slide and squeezing the elastic element, the limiting ring is disengaged from the annular groove, thereby realizing the disconnection between the secondary locking pin and the main locking pin.

[0009] Furthermore, the limiting ring includes an annular ring and a pressing plate, the plane of the annular ring and the plane of the pressing plate are arranged at an angle, and the elastic element is disposed between the pressing plate and the side wall of the outer sleeve; and / or

[0010] The elastic element is a compression spring.

[0011] Furthermore, a positioning groove is provided on the side wall of the outer sleeve, and one end of the elastic element is disposed in the positioning groove.

[0012] Furthermore, the limiting ring is provided with a guide groove, which extends along the sliding direction of the limiting ring. A guide structure is provided in the limiting through groove, which is disposed in the guide groove so as to restrict the limiting ring from disengaging from the limiting through groove by cooperating with the guide groove.

[0013] Furthermore, the guide structure is a positioning post, and the lower end of the outer sleeve is provided with an insertion hole in a direction parallel to the axial direction. The insertion hole is connected to the limiting through groove so that the positioning post is inserted into the insertion hole and extends into the limiting through groove. The opposite side walls of the outer sleeve are both provided to form the limiting through groove.

[0014] Furthermore, the lower end of the main locking pin is provided with a first receiving groove, and a first magnetic attracting element is provided in the first receiving groove. The upper end of the secondary locking pin is provided with a second receiving groove, and a second magnetic attracting element is provided in the second receiving groove, so that the secondary locking pin and the main locking pin are magnetically connected by the magnetic attraction between the first magnetic attracting element and the second magnetic attracting element.

[0015] Furthermore, the main locking pin includes a coupled pin body and a connector to form a columnar structure by combining the pin body and the connector. The first connecting hole is opened on the connector, the first receiving groove is opened at the lower end of the pin body, the pin body is disposed inside the outer sleeve, and the limiting structure is disposed between the inner wall of the outer sleeve and the pin body.

[0016] Furthermore, the lower end of the connector is provided with a threaded rod, and the upper end of the column is provided with a threaded hole, so that the column and the connector are joined together by threading the threaded rod with the threaded hole; and / or

[0017] The limiting structure includes a first limiting step and a second limiting step. The first limiting step is disposed on the inner wall of the outer sleeve, and the second limiting step is disposed on the outer circumferential surface of the column. The second limiting step is located below the first limiting step, so that the outer sleeve is restricted from sliding off the main locking column by the first limiting step and the second limiting step abutting against each other.

[0018] Furthermore, the first connecting hole and / or the second connecting hole are circular holes extending in a direction perpendicular to the axial direction.

[0019] Furthermore, the second receiving groove extends axially along the secondary locking pin, and the second receiving groove is not connected to the second connecting hole.

[0020] As can be seen from the above technical solution, the magnetic quick-release connection structure of this utility model magnetically connects the upper end of the secondary locking pin to the lower end of the main locking pin. When the outer sleeve is slidably fitted onto the secondary locking pin, the limiting ring is engaged in the annular groove, thereby keeping the outer sleeve and the secondary locking pin axially locked, thus preventing the magnetic connection between the secondary locking pin and the main locking pin from accidentally breaking off. The designed locking assembly locks the outer sleeve and the secondary locking pin relative to each other, thereby improving the reliability and safety of the connection structure. Furthermore, by pushing and pressing the limiting ring to slide and squeezing the elastic element, the limiting ring is disengaged from the annular groove, thus realizing the disconnection between the secondary locking pin and the main locking pin. Users can adjust the locking or unlocking state of the locking assembly according to actual needs. The quick-release connection is convenient to use and simple and quick to operate.

[0034] 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.

[0035] Please refer to the following: Figures 1 to 7 This embodiment provides a magnetic quick-release connection structure, including:

[0036] The main locking pin 100 is generally columnar in shape, and a first connecting hole 111 is provided at the upper end of the main locking pin 100 in a transverse direction.

[0037] The secondary locking post 200 is generally columnar in shape. The lower end of the secondary locking post 200 is provided with a second connecting hole 220 in the transverse direction. The upper end of the secondary locking post 200 is detachably magnetically connected to the lower end of the main locking post 100. The outer surface of the upper end of the secondary locking post 200 is provided with an annular groove 210.

[0038] The locking assembly 300 includes an outer sleeve 330, an elastic element 320, and a limiting ring 310. The outer sleeve 330 is slidably sleeved on the main locking pin 100 along the axial direction, and a limiting structure is provided between the outer sleeve 330 and the main locking pin 100 to prevent the outer sleeve 330 from slipping off the main locking pin 100. A limiting groove 331 is formed on the side wall of the outer sleeve 330, and the limiting ring 310 is slidably disposed in the limiting groove 331. The elastic element 320... The limiting ring 310 is positioned between the side wall of the outer sleeve 330 and the inner sleeve 330. When the outer sleeve 330 is slidably sleeved on the upper end of the secondary locking pin 200, the limiting ring 310 is engaged in the annular groove 210, thereby keeping the outer sleeve 330 and the secondary locking pin 200 axially locked. Furthermore, by pushing and pressing the limiting ring 310 to slide and squeezing the elastic element 320, the limiting ring 310 is disengaged from the annular groove 210 to unlock the device, thereby disconnecting the secondary locking pin 200 from the main locking pin 100.

[0039] As can be seen, in this embodiment, the upper end of the secondary locking pin 200 is magnetically connected to the lower end of the main locking pin 100. When the outer sleeve 330 is slidably sleeved on the secondary locking pin 200, it is locked in the annular groove 210 by the limiting ring 310, thereby keeping the outer sleeve 330 and the secondary locking pin 200 axially locked, thus preventing the magnetic connection between the secondary locking pin 200 and the main locking pin 100 from accidentally breaking off. The designed locking assembly 300 makes the outer sleeve 330 and the secondary locking pin 200 relatively locked, thereby improving the reliability and safety of the connection structure. Furthermore, by pushing and pressing the limiting ring 310 to slide and squeezing the elastic element 320, the limiting ring 310 is disengaged from the annular groove 210, thereby realizing the disconnection between the secondary locking pin 200 and the main locking pin 100. Users can adjust the locking or unlocking state of the locking assembly 300 according to actual needs. The quick-release connection is convenient to use and simple and quick to operate. In addition, the structure is simple and compact, stable and reliable, and has low production cost.

[0040] In this embodiment, the limiting ring 310 includes an annular ring 311 and a pressing plate 312. The plane of the annular ring 311 and the plane of the pressing plate 312 are set at an angle, preferably a right angle. The pressing plate 312 and the outer sleeve 330 are integrally formed, and the elastic element 320 is disposed between the side wall of the pressing plate 312 and the outer sleeve 330. The elastic element 320 is a compression spring.

[0041] Specifically, the outer sleeve 330 has a positioning groove 332 on its side wall, and one end of the elastic member 320 is disposed in the positioning groove 332 so that the elastic member 320 can apply an outward force to the annular ring 311.

[0042] Furthermore, the limiting ring 310 is provided with a guide groove 313, which extends along the sliding direction of the limiting ring 310. A guide structure is provided in the limiting through groove 331, which is located in the guide groove 313. The guide structure cooperates with the guide groove 313 to restrict the limiting ring 310 from disengaging from the limiting through groove 331.

[0043] One end of the guide groove 313 is connected to the inner ring hole of the annular ring 311, so that the annular ring 311 is engaged in the annular groove 210 of the secondary locking pin 200 through the edge of the inner ring hole of the annular ring 311, thereby locking the secondary locking pin 200.

[0044] In this embodiment, the guide structure is a positioning post 333. The lower end of the outer sleeve 330 is provided with an insertion hole 334 in a direction parallel to the axial direction. The insertion hole 334 is connected to the limiting through groove 331. The positioning post 333 and the insertion hole 334 are interference-fitted so that the positioning post 333 is inserted into the insertion hole 334 and extends into the limiting through groove 331. The positioning post 333 is located in the guide groove 313 of the limiting ring 310. The opposite side walls of the outer sleeve 330 are both provided to form the limiting through groove 331.

[0045] When it is necessary to unlock and disconnect, the pressing plate 312 drives the annular ring 311 to slide and compress the elastic element 320. The edge of the inner ring hole of the annular ring 311 disengages from the annular groove 210 of the secondary locking pin 200. The inner ring hole of the annular ring 311 is aligned with the upper end of the secondary locking pin 200, so that the outer sleeve 330 and the secondary locking pin 200 are unlocked. The outer sleeve 330 can slide upward along the main locking pin 100, and then the secondary locking pin 200 can be pulled downward to disconnect the magnetic connection between the secondary locking pin 200 and the main locking pin 100, so that the secondary locking pin 200 can be separated and removed for use.

[0046] Furthermore, the lower end of the main locking pin 100 is provided with a first receiving groove 124, and a first magnetic attracting member 123 is provided in the first receiving groove 124. The upper end of the secondary locking pin 200 is provided with a second receiving groove 230, and a second magnetic attracting member 231 is provided in the second receiving groove 230, so that the secondary locking pin 200 and the main locking pin 100 are magnetically connected by the magnetic attraction between the first magnetic attracting member 123 and the second magnetic attracting member 231.

[0047] The first magnetic attractor 123 and the second magnetic attractor 231 are both cylindrical, the first receiving groove 124 and the second receiving groove 230 are both circular blind holes, the first magnetic attractor 123 is embedded and fixed in the first receiving groove 124, and the second magnetic attractor 231 is embedded and fixed in the second receiving groove 230.

[0048] Specifically, the main locking pin 100 includes a pin body 120 and a connector 110 that are joined together to form a columnar structure. A first connecting hole 111 is opened on the connector 110, and a first receiving groove 124 is opened at the lower end of the pin body 120. The pin body 120 is disposed inside the outer sleeve 330. A limiting structure is disposed between the inner wall of the outer sleeve 330 and the pin body 120. The outer sleeve 330 is installed between the pin body 120 and the connector 110 through a detachable connection between the pin body 120 and the connector 110. The connector 110 is located outside the upper end of the outer sleeve 330, and the pin body 120 is located inside the outer sleeve 330.

[0049] Furthermore, the lower end of the connector 110 is provided with a threaded rod 112, and the upper end of the column 120 is provided with a threaded hole 121, so that the column 120 and the connector 110 are combined by threading the threaded rod 112 and the threaded hole 121.

[0050] In this embodiment, the limiting structure includes a first limiting step and a second limiting step 122. The first limiting step is disposed on the inner wall of the outer sleeve 330, and the second limiting step 122 is disposed on the outer peripheral surface of the column 120. The second limiting step 122 is located below the first limiting step, so that the outer sleeve 330 is restricted from sliding off the main locking column 100 by the first limiting step and the second limiting step 122 abutting against each other.

[0051] Specifically, the first connecting hole 111 and / or the second connecting hole 220 are circular holes extending in a direction perpendicular to the axial direction, so as to be connected to an external hanging ring or belt buckle through the first connecting hole 111 and the second connecting hole 220 respectively for use.

[0052] Furthermore, the second receiving groove 230 extends axially along the secondary locking post 200, and the second receiving groove 230 is not connected to the second connecting hole 220.

[0053] As can be seen from the above description, the embodiments of this utility model achieve the following technical effects:

[0054] The magnetic quick-release connection structure of this utility model magnetically connects the upper end of the secondary locking pin 200 with the lower end of the main locking pin 100. When the outer sleeve 330 is slidably sleeved on the secondary locking pin 200, it is locked in the annular groove 210 by the limiting ring 310, thereby keeping the outer sleeve 330 and the secondary locking pin 200 axially locked, thus preventing the magnetic connection between the secondary locking pin 200 and the main locking pin 100 from accidentally breaking off. The designed locking assembly 300 locks the outer sleeve 330 and the secondary locking pin 200 relative to each other, thereby improving the reliability and safety of the connection structure. Furthermore, by pushing and pressing the limiting ring 310 to slide and squeezing the elastic element 320, the limiting ring 310 is disengaged from the annular groove 210, thereby realizing the disconnection between the secondary locking pin 200 and the main locking pin 100. Users can adjust the locking or unlocking state of the locking assembly 300 according to actual needs, which is convenient to use and simple and quick to operate.
