[0044] The embodiments of the present invention are described in detail below. The embodiments described with reference to the accompanying drawings are exemplary. Figure 1-Figure 13 The fastener 100 according to the embodiment of the utility model comprises: a body 10, at least one swinging member 20, and at least one plug-in member 30. The fastener 100 has a first direction A, a second direction B and a third direction C, which are orthogonal to each other.

[0045] Specifically, if Figure 1-Figure 13 As shown, a accommodating cavity 11 is defined in the body 10, and at least one opening 12 is formed on the side wall of the accommodating cavity 11, and the opening 12 passes through the outer circumference of the body 10; one end of the swinging member 20 is pivotally connected to the body 10 at the opening 12, and the other end of the swinging member 20 can swing around one end of the swinging member 20, and the swinging member 20 has a first matching portion 23; the plug-in component 30 is at least partially matched in the accommodating cavity 11, and the plug-in component 30 has a second matching portion 35, and the first matching portion 23 and the second matching portion 35 can be separated and matched. During the matching process between the first matching portion 23 and the second matching portion 35, at least part of the swinging member 20 protrudes from the outer circumference of the body 10; wherein the first matching portion 23 extends obliquely from one end of the swinging member 20 to the other end in the direction toward the center of the accommodating cavity 11; or the second matching portion 35 extends obliquely from one end of the swinging member 20 to the other end in the direction toward the center of the accommodating cavity 11.

[0046] Combination Figure 1-Figure 6The main body 10 extends along the first direction. The main body 10 is a columnar structure or a rod-shaped structure. The lower end of the main body 10 along the first direction is a pointed end. The outer contour of the cross section of the main body 10 perpendicular to the first direction can be circular, square or other regular or irregular shapes, which is convenient for loading and unloading the fastener 100. The upper end of the main body 10 along the first direction is open and is used for assembling and disassembling the plug-in component 30 in the accommodating cavity 11. The lower end of the main body 10 along the first direction is a closed end. The plug-in component 30 extends along the first direction. The lower end of the plug-in component 30 along the first direction has a chamfered surface or a small end area, which is convenient for the movement of the plug-in component 30 in the accommodating cavity 11 and the loading and unloading of the plug-in component 30.

[0047] The swinging member 20 can be swingably engaged at the opening 12, and the swinging member 20 can swing between the storage position and the extended position relative to the body 10. The plug-in connector 30 is engaged in the accommodating cavity 11, and the first engaging portion 23 of the swinging member 20 is located in the accommodating cavity 11. In some embodiments, the first engaging portion 23 extends obliquely from one end of the swinging member 20 to the other end in a direction away from the center of the accommodating cavity 11. Alternatively, the second engaging portion 35 extends obliquely from one end of the swinging member 20 to the other end in a direction away from the center of the accommodating cavity 11. Then, the oblique extension of the first engaging portion 23 of the swinging member 20 or the second engaging portion 35 of the plug-in connector 30 can realize that when the plug-in connector 30 moves in the accommodating cavity 11 along the axial direction of the body 10, through the cooperation between the first engaging portion 23 and the second engaging portion 35, the plug-in connector 30 can push the swinging member 20 to swing between the storage position and the extended position.

[0048] Optionally, a first mating surface is formed on the first mating portion 23 of the swinging member 20, and a second mating surface is formed on the second mating portion 34 of the plug-in member 30. When the first mating surface is mated with the second mating surface, a portion of the swinging member 20 is mated at the opening 12, and a portion protrudes from the outer peripheral surface of the fastener 100 body 10, and the swinging member 20 is located in the extended position. When the first mating surface is separated from the second mating surface, the swinging member 20 is located in the opening 12 and the accommodating cavity 11, and the swinging member 20 is located in the storage position.

[0049] The accommodating cavity 11 extends along the first direction A, and the openings 12 may be multiple, and the multiple openings 12 are arranged at intervals along the circumference of the body 10, and the openings 12 penetrate the side wall of the body 10 along the radial direction of the body 10. In this embodiment, taking the provision of two openings 12 opposite to each other along the radial direction of the body 10 as an example, the openings 12 penetrate the side wall of the body 10 along the second direction B. The swinging member 20 extends along the first direction A, and the upper end of the swinging member 20 along the first direction A is rotatably connected to the housing, and the lower end of the swinging member 20 along the first direction A can swing at the opening 12 along the second direction B relative to the outlet between the storage position and the extended position.

[0050] According to the fastener 100 of the embodiment of the utility model, when the first matching portion 23 is separated from the second matching portion 35, it is suitable for inserting the fastener 100 into the ground, stone cracks or other installation positions, or conveniently taking it out from the installation position. When the first matching portion 23 is matched with the second matching portion 35, a part of the swinging member 20 is matched at the opening 12, and a part protrudes from the outer peripheral surface of the fastener 100 body 10, so that the fastener 100 is firmly embedded in the installation position. The plug-in member 30 can limit the swinging member 20, so that the swinging member 20 can be fixed in the opening 12 or protrude from the outer peripheral surface of the body 10 to maintain the current position. The setting of the swinging member 20 facilitates the reuse of the fastener 100, thereby saving resources, and is also convenient for taking it out from the installation position to reduce damage to the environment, which is conducive to improving the practicality of the fastener 100.

[0051] According to some embodiments of the present invention, Figure 1-Figure 6 As shown, the opening 12 extends along the axial direction of the body 10; the plug-in connector 30 is movable along the axial direction of the body 10 so that the swing member 20 can swing between the storage position and the extended position; when the swing member 20 is in the storage position, the first matching portion 23 is separated from the second matching portion 35, and the swing member 20 is stored in the opening 12; when the swing member 20 is in the extended position, the first matching portion 23 is matched with the second matching portion 35, and the swing member 20 protrudes from the outer peripheral surface of the body 10. One end of the swing member 20 is pivotally connected to one end of the opening 12 in the axial direction of the body 10, and the other end of the swing member 20 can swing around one end of the swing member 20. When the swing member 20 is in the storage position, the swing member 20 is stored in the opening 12, and at this time, the first matching portion 23 of the swing member 20 is separated from the second matching portion 35 of the plug-in connector 30. When the swing member 20 is in the extended position, the swing member 20 protrudes from the outer peripheral surface of the body 10. At this time, the first matching portion 23 of the swing member 20 matches with the second matching portion 35 of the plug-in component 30, and the first matching portion 23 and the second matching portion 35 are arranged opposite to each other along the second direction of the fastener 100. The opening 12 extends along the first direction A, and the shape of the opening 12 is adapted to the shape of the swing member 20.

[0052] Thus, the connector 30 can push the swinging member 20 to swing by the cooperation between the first cooperation portion 23 and the second cooperation portion 35. One end of the swinging member 20 is pivotally connected to one end of the opening 12 in the axial direction of the main body 10 to facilitate the swinging member 20 to swing between the storage position and the extended position.

[0053] According to some embodiments of the present invention, Figure 2 and Figure 3As shown, when the swing member 20 is in the storage position, one end of the swing member 20 is located in the opening 12, and a part of the other end of the swing member 20 extends into the accommodating cavity 11. When the swing member 20 is in the storage position, a part of the swing member 20 is in the opening 12, and another part of the swing member 20 is in the storage cavity. The side surface of the swing member 20 away from the center of the accommodating cavity 11 along the second direction B is flush with the outer peripheral surface of the body 10, and the side surface of the swing member 20 away from the center of the accommodating cavity 11 is an arc surface. Therefore, when the swing member 20 is in the storage position, the swing member 20 is flush with the outer peripheral surface of the body 10, which is convenient for the storage of the fastener 100, and also convenient for the fastener 100 to be smoothly installed in the use scene such as land or trees, making the installation of the fastener 100 easier and improving the user experience.

[0054] In some embodiments, the cross-sectional area of ​​the other end of the swing member 20 is greater than the cross-sectional area of ​​one end of the swing member 20. The cross-sectional area of ​​the swing member 20 gradually increases from one end to the other end along the first direction A, and the projection of the swing member 20 in the third direction C is a fan-shaped structure. When the swing member 20 is in the extended position, a portion of the swing member 20 is located in the opening 12, and another portion of the swing member 20 protrudes from the body 10. Thus, the structural arrangement of the swing member 20 facilitates that when the swing member 20 is in the extended position, there is a partially protruding structure on the outer peripheral surface of the fastener 100, so that the fastener 100 can be firmly embedded in the soil or trees, thereby improving the firmness of the installation of the fastener 100.

[0055] According to some embodiments of the present invention, Figure 6 As shown, the thickness of the other end of the swing member 20 in the radial direction of the body 10 is greater than the thickness of one end of the swing member 20 in the radial direction of the body 10. The thickness of the other end of the swing member 20 in the second direction B is greater than the thickness of one end of the swing member 20 in the second direction B. Thus, the structural strength of the swing member 20 can be enhanced, thereby enhancing the structural strength of the fastener 100 as a whole, improving the reliability and stability of the fastener 100 during assembly, and extending the service life of the fastener 100.

[0056] According to some embodiments of the present invention, Figure 2-Figure 6 As shown, one end of the swing member 20 is pivotally connected to one end of the opening 12 in the axial direction of the main body 10 through a pivot shaft 14; both end faces of the swing member 20 are formed as arc surfaces, and both side walls of the opening 12 in the axial direction of the main body 10 are formed as arc surfaces.

[0057] The fastener 100 further includes a pivot shaft 14, which extends along the third direction C. A first matching hole 13 is formed on the body 10 and penetrates the body 10 along the third direction C. A second matching hole 21 is formed on the swinging member 20 and penetrates the body 10 along the third direction C. The pivot shaft 14 is inserted into the first matching hole 13 and the second matching hole 21 to fix the swinging member 20 on the body 10. The first matching hole 13 is formed at the upper end of the opening 12 along the first direction A, and the second matching hole 21 is formed at the upper end of the swinging member 20 along the first direction A. The upper end of the swinging member 20 along the first direction A is pivotally connected to the upper end of the opening 12 along the first direction A through the pivot shaft 14, and the lower end of the swinging member 20 along the first direction A can swing around the pivot shaft 14 as the axis.

[0058] Therefore, when the swinging member 20 rotates relative to the opening 12, the gap between the upper end surface of the swinging member 20 along the first direction A and the upper end surface of the opening 12 along the first direction A is constant, and the gap between the lower end surface of the swinging member 20 along the first direction A and the lower end surface of the opening 12 along the first direction A is constant. This can prevent sand, stone, soil or other debris from entering the fastener 100 during use, causing the swinging member 20 to be unable to swing, thereby extending the service life of the fastener 100.

[0059] According to some embodiments of the present invention, Figure 2-Figure 6 As shown, the center of the arc surface of the end surface of the two ends of the swing member 20 is the pivot center of the swing member 20. The swing member 20 rotates relative to the opening 12 with the pivot axis 14 as the center. The end surfaces of the swing member 20 and the opening 12 along the first direction A are arc surfaces with the pivot axis 14 as the center. The arc surface of the swing member 20 is adapted to the arc surface of the opening 12. The upper end of the swing member 20 along the first direction is formed with an arc surface 1 24, and the lower end of the swing member 20 along the first direction is formed with an arc surface 25. Therefore, when the swing member 20 swings, it can be ensured that the distance between the arc surface 1 24 and the pivot center is equal everywhere, and the distance between the arc surface 25 and the pivot center is equal everywhere, so that the gaps between the upper and lower ends of the swing member 20 along the first direction and the upper and lower ends of the opening 12 along the first direction are constant, thereby improving the stability and reliability of the movement of the swing member 20.

[0060] According to some embodiments of the present invention, Figure 6As shown, one end of the accommodating cavity 11 is open, and the plug-in connector 30 is suitable for being assembled into the accommodating cavity 11 through one end of the accommodating cavity 11, and one end of the swinging member 20 is adjacent to one end of the accommodating cavity 11; when the plug-in connector 30 moves from one end of the accommodating cavity 11 toward the other end of the accommodating cavity 11, the swinging member 20 swings from the storage position to the extended position. The upper end of the accommodating cavity 11 along the first direction A is open, and the upper end of the swinging member 20 along the first direction A is adjacent to the upper end of the accommodating cavity 11 along the first direction A. The plug-in connector 30 extends along the first direction A, and the plug-in connector 30 is inserted into the accommodating cavity 11 from the open end of the accommodating cavity 11, and the plug-in connector 30 moves from one end of the accommodating cavity 11 to the other end along the first direction A. Therefore, the plug-in connector 30 is arranged in the accommodating cavity 11 and cooperates with the swinging member 20 to limit the swinging member 20, and the plug-in connector 30 can make the swinging member 20 move from the storage position to the extended position, ensuring the reliability and functionality of the fastener 100.

[0061] According to some embodiments of the present invention, Figure 1-Figure 6 As shown, the connector 30 is detachably mated with the accommodating cavity 11, and the connector 30 has a switchable first mating state and a second mating state relative to the accommodating cavity 11. When the connector 30 is in the first mating state, the swinging member 20 is locked to keep the swinging member 20 in the storage position. When the connector 30 switches from the first mating state to the second mating state, the connector 30 releases the swinging member 20, and the connector 30 is suitable for pushing the swinging member 20 to swing from the storage position to the extended position.

[0062] When the plug connector 30 is in the first mating state, the plug connector 30 is located in the accommodating cavity 11, and the plug connector 30 is mated with the swinging member 20, and the plug connector 30 can limit the swinging member 20, so that the swinging member 20 is kept in the storage position. The plug connector 30 is taken out of the accommodating cavity 11, and the plug connector 30 is switched to the second mating state and then inserted into the accommodating cavity 11. During the insertion process of the plug connector 30, the lower end of the plug connector 30 along the first direction A stops against the swinging member 20, and pushes the lower end of the swinging member 20 along the first direction A to swing toward the extended position. After the plug connector 30 is fully inserted into the accommodating cavity 11, it stops moving. The plug connector 30 and the swinging member 20 are mated, and the swinging member 20 are limited, so that the swinging member 20 is kept in the extended position.

[0063] Thus, the connector 30 can be detachably matched with the accommodating cavity 11 and with the swinging member 20, so that the swinging member 20 is maintained in the storage position or the extended position, which is convenient for the installation of the fastener 100 and also convenient for the recycling and reuse of the fastener 100, and can improve the structural stability of the fastener 100.

[0064] According to some embodiments of the present invention, Figure 3 and Figure 6As shown, a locking groove 22 is formed on one of the swing member 20 and the plug-in member 30, and a locking protrusion 31 is provided on the other of the swing member 20 and the plug-in member 30. When the plug-in member 30 is in the first mating state, the locking protrusion 31 is engaged in the locking groove 22 to keep the swing member 20 in the storage position. For example, a locking groove 22 is formed on the swing member 20, and the locking groove 22 extends along the first direction A. The locking groove 22 is formed by a part of the surface of one side of the swing member 20 along the third direction C being concave toward a side close to the center of the swing member 20. A locking protrusion 31 is formed on the plug-in member 30, and the locking protrusion 31 extends along the first direction A. The locking protrusion 31 is formed by a part of the surface of one side of the swing member 20 along the third direction C being protruded toward a direction away from the swing member 20. Thus, the locking protrusion 31 of the connector 30 fits in the locking groove 22 of the swinging member 20. The arrangement of the locking protrusion 31 and the locking groove 22 can enable the connector 30 to limit the swinging member 20 in the second direction B, so as to keep the swinging member 20 in the storage position.

[0065] According to some embodiments of the present invention, Figure 6 As shown, there are two openings 12, and the two openings 12 are opposite to each other along the radial direction of the main body 10; there are two swinging members 20, and the two swinging members 20 are respectively matched with the two openings 12; there are two connectors 30, when the two connectors 30 are in the first matching state, the connectors 30 lock the two swinging members 20, and when the two connectors 30 are in the second matching state, the two connectors 30 respectively push the corresponding swinging members 20 to swing from the storage position to the extended position.

[0066] The two openings 12 are arranged opposite to each other along the second direction B, and the two swinging members 20 are arranged opposite to each other along the second direction B. When the two connectors 30 are in the first mating state, the two connectors 30 are arranged opposite to each other along the third direction C on one side surface of the locking protrusion 31 , and the two swinging members 20 are located between the two connectors 30 .

[0067] In some embodiments, locking grooves 22 are formed on both side surfaces of the swinging member 20 along the third direction C, and two locking protrusions 31 are formed on one side surface of the connector 30 along the third direction C. The two locking protrusions 31 are arranged at intervals along the second direction B. When the connector 30 is in the first mating state, the two locking protrusions 31 on one connector 30 respectively cooperate with the locking grooves 22 on the same side surface of the two swinging members 20 along the third direction C, and the two locking protrusions 31 on the other connector 30 respectively cooperate with the locking grooves 22 on the other side surface of the two swinging members 20 along the third direction C. Both connectors 30 can limit the two swinging members 20 so that the two swinging members 20 remain in the storage position.

[0068] When the plug connectors 30 are in the second mating state, the other side planes of the two plug connectors 30 without the locking protrusions 31 contact and stop along the second direction B, and the side surfaces of the two plug connectors 30 with the locking protrusions 31 are respectively arranged opposite to the two swing members 20 along the second direction B. The two plug connectors 30 are mated in the accommodating cavity 11 to push the swing member 20 to swing from the storage position to the extended position.

[0069] Therefore, the setting of the two openings 12 is convenient for accommodating the two swinging members 20. The setting of the two swinging members 20 can improve the reliability of the fastener 100 during use. The setting of the two plug-in members 30 can make the limiting of the swinging members 20 by the plug-in members 30 more reliable, thereby improving the overall reliability of the fastener 100.

[0070] According to some embodiments of the present invention, Figure 2-Figure 5 As shown, when the two connectors 30 are in the first mating state, the two connectors 30 are opposite to each other along the radial direction of the body 10, and the connecting line of the two connectors 30 is perpendicular to the connecting line of the two swing members 20; when the two connectors 30 are in the second mating state, the two connectors 30 are located between the two swing members 20.

[0071] When the two connectors 30 are in the first mating state, the two connectors 30 are arranged on one side surface of the locking protrusion 31 and are arranged opposite to each other along the second direction B. The connector 30 is an axisymmetric structure, and the symmetry axis of the connector 30 is parallel to the third direction C. The swing member 20 is an axisymmetric structure, and the symmetry axis of the swing member 20 is parallel to the second direction B. The symmetry axes of the two connectors 30 are perpendicular to the symmetry axes of the two swing members 20. Along the third direction C, the two swing members 20 are arranged between the two connectors 30. When the two connectors 30 are in the second mating state, along the second direction B, the two connectors 30 are located between the two swing members 20.

[0072] Therefore, when the two connectors 30 are in the first mating state, the two connectors 30 and the two swinging members 20 can be completely located in the accommodating cavity 11 and the opening 12, making full use of the space in the accommodating cavity 11. When the two connectors 30 are in the second mating state, the two connectors 30, while playing the role of limiting the swinging member 20, improve the space utilization rate inside the fastener 100, facilitate the storage of the fastener 100, and help to improve the practicability of the fastener 100 and simplify the internal structure of the fastener 100.

[0073] According to some embodiments of the present invention, Figure 7-Figure 13 As shown, the plug-in component 30 and the swing component 20 are threadedly matched along the axial direction of the body 10, so that the first matching portion 23 and the second matching portion 35 can be separated and matched.

[0074] In some embodiments, the connector 30 is a threaded rod structure with a threaded outer wall. The connector 30 extends along the first direction A. The swinging member 20 and the inner wall of the accommodating cavity 11 are both provided with threads suitable for cooperating with the connector 30. The threaded end of the connector 30 moves from one end of the accommodating cavity 11 toward the other end of the accommodating cavity 11 to push the swinging member 20 to swing from the storage position to the extended position.

[0075] Thus, when the plug-in component 30 is installed in the accommodating cavity 11, the swinging member 20 can be pushed to swing to the extended position, and the plug-in component 30 and the swinging member 20 are threadedly matched, so that the plug-in component 30 can limit the swinging member 20 to keep the swinging member 20 in the extended position. The threaded match also has the characteristics of simple structure, high reliability, convenient assembly and detachability, which can make the assembly between the plug-in component 30 and the swinging member 20 easier, improve the reliability of the fastener 100 when in use, and also facilitate the reuse of the fastener 100.

[0076] According to some embodiments of the present invention, Figure 7-Figure 13 As shown, there are multiple swing members 20, which are arranged at intervals along the circumference of the body 10, and the inner wall of the accommodating cavity 11 defines a threaded hole, and the plug-in member 30 cooperates with the threaded hole.

[0077] In some embodiments, threads are provided on the outer peripheral wall of the plug-in component 30, and threads are provided on the inner wall of the accommodating cavity 11, and the threads on the plug-in component 30 cooperate with the threads on the accommodating cavity 11. Thus, the threaded hole on the inner wall of the accommodating cavity 11 cooperates with the plug-in component 30, which is conducive to improving the assembly firmness between the plug-in component 30 and the body 10, so that the plug-in component 30 can be more reliably installed in the accommodating cavity 11, and the structural strength of the fastener 100 is improved.

[0078] According to some embodiments of the present invention, Figure 6 and Fig.13As shown, one end of the accommodating cavity 11 is open, and the plug-in connector 30 is suitable for being assembled into the accommodating cavity 11 through one end of the accommodating cavity 11; a first through hole 33 is formed on the plug-in connector 30, and the first through hole 33 is adjacent to one end of the accommodating cavity 11; or a groove is formed on the plug-in connector 30, and the groove is adjacent to one end of the accommodating cavity 11. A lug 32 is formed at the upper end of the plug-in connector 30 along the first direction A, and a first through hole 33 is formed on the lug 32, and the first through hole 33 is arranged through the lug 32 along the thickness direction of the lug 32. The groove is formed by a part of the upper end of the lug 32 along the first direction A being recessed in the direction away from the plug-in connector 30 along the thickness direction. Or a groove is formed on the lug 32 of the plug-in connector 30, and the first through hole 33 is formed on the groove. Therefore, the provision of the first through hole 33 facilitates the user to pass a rope through the first through hole 33 for installing or removing the plug-in connector 30, thereby simplifying the difficulty of installing and removing the plug-in connector 30. The groove formed on the connector 30 also facilitates the user to apply force to the connector 30 when removing or installing the connector 30, thereby improving the user experience comfort.

[0079] According to some embodiments of the present invention, Figure 6 As shown, when both a through hole and a groove are formed on the plug connector 30, the groove is connected to the first through hole 33. That is, the first through hole 33 is arranged to penetrate the groove along the thickness direction of the plug connector 30. Thus, the difficulty of installing and removing the plug connector 30 can be simplified, and no special tools are required, so that the assembly and removal of the plug connector 30 can be completed manually in a short time.

[0080] According to some embodiments of the present invention, Fig.13 As shown, a second through hole 16 is formed on the body 10, and the second through hole 16 is adjacent to one end of the accommodating cavity 11. The second through hole 16 is arranged to penetrate the body 10 along the thickness direction of the body 10, and the second through hole 16 is arranged at the upper end of the body 10 along the first direction A. Therefore, the arrangement of the second through hole 16 facilitates the user to pass a rope through the second through hole 16 for installing or removing the fastener 100. When the user uses the fastener 100 and installs the fastener 100 in the land or a tree, the user installs the plug-in component 30 in the accommodating cavity 11 to swing the swinging component 20 to the extended position, so that the fastener 100 is firmly fixed in the land or the tree. When the user recycles the fastener 100, the user first takes out the connector 30 from the accommodating cavity 11 to release the limit of the connector 30 on the swinging member 20, and then passes the rope into the second through hole 16 to take the fastener 100 out of the ground or the tree. During this process, the swinging member 20 naturally swings to the storage position, and the fastener 100 can be recovered, which is convenient for the reuse of the fastener 100.

[0081] According to some embodiments of the present invention, Fig.13As shown, the body 10 is provided with two standing ears 15 opposite to each other in the radial direction of the body 10, and the two standing ears 15 are respectively formed with second through holes 16. The standing ears 15 are formed by a portion of the upper end surface of the body 10 along the first direction A protruding in the first direction A in a direction away from the body 10, and the two standing ears 15 are arranged at intervals along the circumference of the body 10, and the two standing ears 15 are arranged opposite to each other along the second direction B of the body 10. The second through hole 16 penetrates the standing ears 15 along the thickness direction of the standing ears 15.

[0082] Therefore, the two vertical ears 15 are respectively formed with second through holes 16 to facilitate the installation of the rope. The arrangement of the two vertical ears 15 can also facilitate the installation and removal of the fastener 100 when the user applies force to the rope, thereby reducing the force applied to each vertical ear 15, extending the service life of the vertical ears 15, and further extending the service life of the fastener 100.
