Description

Technical Field

[0001] This invention relates to the field of pipeline installation technology, and more specifically to a pipeline anchoring device. Background Technology

[0002] Fire protection pipes and other large-diameter pipes in civil and industrial buildings need to be anchored to walls or beams using supports during installation.

[0003] After installation, pipelines may move or deform axially under external forces and environmental influences, affecting their stability and potentially causing cracking and shortening their service life. Summary of the Invention

[0004] The purpose of this invention is to provide a pipe anchoring device to improve the service life of pipes.

[0005] To achieve the above objectives, the technical solution proposed by this invention is as follows: A pipe anchoring device includes an anchoring mechanism, a pipe, and a self-locking mechanism. The anchoring mechanism includes a load-bearing beam and an anchoring assembly. The load-bearing beam is connected to an anchoring foundation via the anchoring assembly. The pipe is supported on the load-bearing beam. The self-locking mechanism includes a locking head structure and a locking seat assembly arranged along the axial direction of the pipe. One of the locking head structure and the locking seat assembly is connected to the pipe, and the other is connected to the load-bearing beam. The self-locking mechanism is configured to: when the pipe moves a first preset distance in a first direction, drive the locking head structure and the locking seat assembly to lock the pipe's displacement in a second direction; when the pipe continues to move a second preset distance in the first direction, release the locking head structure and the locking seat assembly from the pipe. The first direction is parallel to the axial direction of the pipe, the second direction is opposite to the first direction, and the second preset distance is less than the first preset distance.

[0006] The pipe anchoring device provided by the present invention is equipped with a self-locking mechanism. When the pipe moves or deforms to a large first preset distance in the first direction, the self-locking mechanism can limit the pipe to prevent excessive movement in the second direction. It also allows the pipe to continue moving a small second preset distance in the first direction to release the limitation on the pipe. This prevents the pipe from continuing to move significantly in the first direction after a large displacement has occurred, reducing the possibility of cracking or other damage to the pipe under excessive vibration and improving the service life of the pipe.

[0007] In addition, the pipe anchoring device according to the above embodiments of the present invention may also have the following additional technical features: In some embodiments of the present invention, the lock seat assembly includes a lock body and a sliding latch, the lock head structure is installed on the pipe, the lock body is connected to the load-bearing beam, the lock body is provided with a sliding rail, the sliding rail is provided with a first locking position and a first unlocking position, the sliding latch is slidably connected to the sliding rail, when the pipe moves a first preset distance along the first direction, the sliding latch moves to the first locking position to lock the displacement of the pipe along the second direction, when the pipe continues to move a second preset distance along the first direction, the lock head structure and the lock seat assembly enter the first unlocking position to release the restriction on the pipe.

[0008] In some embodiments of the present invention, the sliding track includes a first track portion, a second track portion, a third track portion, and a fourth track portion. The end of the first track portion away from the lock head structure and the end of the second track portion form a first acute angle. The other end of the second track portion and the end of the third track portion are connected and form a second acute angle. The ends of the third track portion and the fourth track portion away from the lock head structure are connected and form a third acute angle. The first locking position includes the second acute angle, the first unlocking position includes the third acute angle, the first acute angle and the third acute angle face the same direction, and the second acute angle faces the opposite direction to the first acute angle.

[0009] In some embodiments of the present invention, the end of the first track portion away from the second track portion is connected to the end of the fourth track portion away from the third track portion, so that the first track portion, the second track portion, the third track portion and the fourth track portion form a closed loop.

[0010] In some embodiments of the present invention, the sliding latch includes a sliding member and a latching structure. The sliding member is slidably connected to the sliding track, and the latching structure is connected to the side of the sliding member facing the lock head structure. The latching structure is configured to engage with the lock head structure and disengage from the lock head structure.

[0011] In some embodiments of the present invention, the locking structure includes two latching members, which are respectively hinged to the sliding member and spaced apart in a third direction perpendicular to the axial direction of the pipe. The two latching members are configured to move between a closed state and an unfolded state. In the closed state, the two latching members rotate to engage with the lock head structure respectively, and in the unfolded state, the two latching members rotate to release the engagement with the lock head structure.

[0012] In some embodiments of the present invention, the lock body is provided with two rotation limiting parts, which are arranged at intervals along the third direction. Two latching members are located between the two rotation limiting parts. In the closed state, the two rotation limiting parts abut against the two latching members one by one, so that the two latching members rotate to engage with the lock head structure respectively. In the unfolded state, the two rotation limiting parts and the two latching members form a gap along the axial direction of the pipe, so that the two latching members rotate to release the engagement with the lock head structure.

[0013] In some embodiments of the present invention, the sliding member includes a swing rod and a sliding frame, one end of the swing rod is slidably connected to the sliding track, the other end of the swing rod is hinged to the sliding frame, the locking structure is mounted on the sliding frame, and the sliding frame is configured to move only in the first direction and the second direction when the swing rod moves along the sliding track.

[0014] In some embodiments of the present invention, the lock seat assembly further includes an elastic reset member, which is connected to the sliding latch and the lock body respectively. During the process of the sliding latch moving to the first locking position and the first unlocking position, the elastic reset member is compressed.

[0015] In some embodiments of the present invention, the anchoring mechanism further includes a first connecting component installed on a load-bearing beam, the pipe passing through the first connecting component, and the self-locking mechanism being installed on opposite sides of the first connecting component along the axial direction of the pipe, with the two self-locking mechanisms located on the first connecting component being symmetrically arranged about the first connecting component.

[0019] The principles and features of the present invention are described below with reference to the accompanying drawings. The examples given are only for explaining the present invention and are not intended to limit the scope of the present invention.

[0020] Exemplary embodiments of the present disclosure will now be described in more detail with reference to the accompanying drawings. While exemplary embodiments of the present disclosure are shown in the drawings, it should be understood that the present disclosure may be implemented in various forms and should not be limited to the embodiments set forth herein. Rather, these embodiments are provided so that this disclosure will be thorough and complete, and will fully convey the scope of the disclosure to those skilled in the art.

[0021] It should be understood that the terminology used herein is for the purpose of describing particular exemplary embodiments only and is not intended to be limiting. Unless the context clearly indicates otherwise, the singular forms “a,” “an,” and “described” as used herein may also include the plural forms. The terms “comprising,” “including,” “containing,” and “having” are inclusive and therefore indicate the presence of the stated features, steps, operations, elements, and / or components, but do not exclude the presence or addition of one or more other features, steps, operations, elements, components, and / or combinations thereof. The method steps, processes, and operations described herein are not construed as requiring them to be performed in a particular order described or illustrated unless the order of performance is explicitly indicated. It should also be understood that additional or alternative steps may be used.

[0022] Although terms such as first, second, third, etc., may be used in this document to describe multiple elements, components, regions, layers, and / or segments, these elements, components, regions, layers, and / or segments should not be limited by these terms. These terms may be used only to distinguish one element, component, region, layer, or segment from another. Unless the context clearly indicates otherwise, terms such as "first," "second," and other numerical terms used herein do not imply order or sequence. Therefore, the first element, component, region, layer, or segment discussed below may be referred to as the second element, component, region, layer, or segment without departing from the teachings of the exemplary embodiments.

[0023] For ease of description, spatial relative terms may be used in the text to describe the relationship of one element or feature relative to another element or feature, as shown in the figure. These relative terms include, for example, "inside," "outside," "middle," "outer," "below," "below," "above," "over," etc. Such spatial relative terms are intended to include different orientations of the device in use or operation, other than those depicted in the figure. For example, if the device in the figure is flipped, an element described as "below other elements or features" or "below other elements or features" would subsequently be oriented as "above other elements or features" or "above other elements or features." Therefore, the example term "below" can include both upper and lower orientations. The device may be otherwise oriented (rotated 90 degrees or in other directions), and the spatial relative descriptors used in the text will be interpreted accordingly.

[0024] Fire protection pipelines and other large-diameter pipelines in civil and industrial buildings can experience axial movement and deformation under the influence of external forces such as water flow vibration and earthquakes, as well as external environmental factors such as temperature changes.

[0025] In related technologies, pipe supports include two structural forms: rigid fixed supports and sliding fixed supports. Rigid fixed supports fix the pipe in a fixed position. However, under the aforementioned external forces or environmental factors, the pipe and support will experience significant stress that cannot be released or buffered, easily leading to pipe cracking or support failure. Sliding fixed supports allow the pipe to move along its axial direction, but they cannot effectively restrict the pipe's movement during this process, resulting in significant axial reciprocating displacement of the pipe, which can also easily damage the pipe.

[0026] Therefore, both of the above methods are prone to pipe cracking and damage. Thus, how to effectively limit and fix the pipe and prevent damage to the pipe under external forces or external environmental factors is an urgent problem to be solved in the field of pipe installation.

[0027] In view of this, the present application provides a pipe anchoring device that uses a self-locking mechanism to limit the pipe under large stroke movement or deformation, and allows the pipe to move or deform under small stroke, thereby solving the above-mentioned technical problems.

[0028] Combined with appendix Figure 1 and attached Figure 2 As shown in the figure, this application provides a pipe anchoring device 100, including an anchoring mechanism 10, a pipe 20 and a self-locking mechanism 30. The anchoring mechanism 10 includes a load-bearing beam 11 and an anchoring component 12. One or more pipes 20 can be installed on the load-bearing beam 11. Taking the multiple pipes 20 in the figure as an example, the multiple pipes 20 can be installed at intervals along the length direction of the load-bearing beam 11, and the axial direction or length direction of the pipes 20 is perpendicular to the length direction of the load-bearing beam 11.

[0029] In some embodiments, the pipe 20 can be installed on the load-bearing beam 11 by means of the first connecting component 13. The first connecting component 13 includes a first clamp 131, a first bolt 132 and a first nut 133. The first clamp 131 includes two arc-shaped parts. The two arc-shaped parts can be installed on the load-bearing beam 11 by mechanical fixing methods such as welding and bolt connection. The two arc-shaped parts form a space for the pipe 20 to pass through. The two arc-shaped parts are connected by the first bolt 132 and the first nut 133.

[0030] The anchoring assembly 12 may include multiple anchoring beams 121. One end of the anchoring beam 121 is hinged to the load-bearing beam 11, and the other end is connected to the anchoring foundation 200 through structures such as seismic connectors 122 and anchor bolts 123. The anchoring foundation 200 may be a wall or soil structure.

[0031] The anchoring component 12 in this embodiment can be any component used for anchoring the pipe 20 in the related art, and will not be described in detail in this embodiment.

[0032] In order to limit the movement or deformation of the pipe 20 under large stroke and allow the pipe 20 to move or deform under small stroke, this embodiment includes a self-locking mechanism 30 comprising a lock head structure 31 and a lock seat assembly 32 arranged along the axial direction of the pipe 20. One of the lock head structure 31 and the lock seat assembly 32 is connected to the pipe 20 and the other is connected to the load-bearing beam 11.

[0033] Taking the example of the lock head structure 31 being installed on the pipe 20 and the lock seat assembly 32 being connected to the load-bearing beam 11, the lock head structure 31 can be connected to the pipe 20 through the second connecting assembly 21. The structure of the second connecting assembly 21 is the same as or similar to the structure of the first connecting assembly 13 mentioned above. The lock head structure 31 is installed on the second clamp 211 of the second connecting assembly 21, and the second clamp 211 is tightly fitted onto the pipe 20.

[0034] The lock seat assembly 32 can be directly or indirectly connected to the load-bearing beam 11. For example, the lock seat assembly 32 can be installed on the load-bearing beam 11 through the first connecting assembly 13 mentioned above. Specifically, the lock seat assembly 32 can be installed on the first clamp 131.

[0035] Furthermore, the self-locking mechanism 30 of this embodiment is configured such that when the pipe 20 moves a first preset distance along the first direction X, it drives the lock head structure 31 and the lock seat assembly 32 to lock the displacement of the pipe 20 along the second direction Y, thereby preventing the pipe 20 from moving directly back along the second direction Y after moving a large first preset distance along the first direction X, which would cause the pipe 20 to sway excessively back and forth. At this time, the lock head structure 31 and the lock seat assembly 32 allow the pipe 20 to continue moving a small second preset distance along the first direction X, so that when the pipe 20 shows a tendency to continue moving or deforming along the first direction X, the self-locking mechanism 30 can meet the movement or deformation requirements of the pipe 20.

[0036] Furthermore, as the pipe 20 continues to move along the first direction X to a smaller second preset distance, the lock head structure 31 and the lock seat assembly 32 release their restraints from the pipe 20, thereby allowing the pipe 20 to reset along the second direction Y.

[0037] This limiting and releasing method allows the pipe 20 to first move a large first preset distance along the first direction X after being subjected to a large stress in the first direction X, and then be limited to the displacement in the second direction Y. After being limited by the displacement in the second direction Y, the pipe 20 is subjected to the stress in the first direction X by the locking seat assembly 32 or external stress, and then continues to move a small distance (second preset distance) along the first direction X. Subsequently, the limiting is released, and the pipe 20 can be reset to the initial position.

[0038] Wherein, the first direction X is parallel to the axial direction of the pipe 20, the second direction Y is opposite to the first direction X, and the second preset distance is less than the first preset distance. In some embodiments, the second preset distance is one-tenth to one-fifth of the first preset distance.

[0039] In summary, when the pipe 20 moves or deforms to a large first preset distance along the first direction X, the self-locking mechanism 30 of the pipe anchoring device 100 provided in this embodiment can limit the pipe 20 to prevent excessive movement along the second direction Y, and allow the pipe 20 to continue moving a small second preset distance along the first direction X to release the limitation on the pipe 20. This prevents the pipe 20 from continuing to move a large displacement along the first direction X after a large displacement has occurred, reduces the possibility of cracking or other damage to the pipe 20 under excessive vibration, and improves the service life of the pipe 20.

[0040] Combined with appendix Figure 3-6 As shown, in some examples, the lock seat assembly 32 may optionally include a lock body 321 and a sliding latch 322. The lock head structure 31 is installed on the pipe 20. Specifically, the lock head structure 31 is installed on the pipe 20 via the second connecting assembly 21 described above. The end of the lock head structure 31 facing the lock body 321 is provided with a limiting end, the width of which is greater than the width of the middle part of the lock head structure 31.

[0041] The lock body 321 is connected to the load-bearing beam 11. Specifically, the lock body 321 may be installed on the first connecting component 13 mentioned above, and the lock body 321 is installed on the load-bearing beam 11 through the first connecting component 13.

[0042] In this embodiment, the lock body 321 is provided with a sliding track 3211. The sliding track 3211 is provided with a first locking position 32115 and a first unlocking position 32116. The sliding latch 322 is slidably connected to the sliding track 3211.

[0043] like Figure 1 As shown, at this time, the pipe 20 is not subjected to external stress or environmental disturbance, and the lock head structure 31 is at a certain distance from the lock body 321 and the sliding lock 322.

[0044] like Figure 4 As shown, when the pipe 20 moves along the first direction X, the pipe 20 drives the locking head structure 31 to approach the sliding latch 322 and abut against the sliding latch 322.

[0045] like Figure 5As shown, when the pipe 20 drives the lock head structure 31 to move along the first direction X to the first preset distance, the sliding lock 322 moves to the first locking position 32115 to lock the displacement of the pipe 20 along the second direction Y.

[0046] like Figure 6 As shown, when the pipe 20 continues to move a second preset distance along the first direction X, the lock head structure 31 and the lock seat assembly 32 enter the first unlock position 32116 to release the restriction on the pipe 20, thereby allowing the pipe 20 to return to its original position. Figure 1 The state in.

[0047] After the self-locking mechanism 30 releases the limit on the pipe 20, when the pipe 20 is subjected to a large stress in the first direction X again, the above process is repeated.

[0048] In addition, in order to enable the pipe 20 to first undergo a large displacement in the second direction Y (a third preset distance) under the action of an external force in the second direction Y, and then restrict the displacement of the pipe 20 in the first direction X, the restriction on the pipe 20 can be released after the pipe 20 is allowed to continue to move in the second direction Y to a smaller displacement (a fourth preset distance). This allows the pipe 20 to be restricted by the self-locking mechanism 30 in both the first direction X and the second direction Y. The self-locking mechanism 30 can be installed on opposite sides of the first connecting assembly 13 along the axial direction of the pipe 20, that is, two self-locking mechanisms 30 are installed on each first clamp 131, and the two self-locking mechanisms 30 on the first connecting assembly 13 are symmetrically arranged about the first connecting assembly 13.

[0049] Combined again with the appendix Figure 3-6 As shown, in some examples, optionally, the sliding track 3211 includes a first track portion 32111, a second track portion 32112, a third track portion 32113, and a fourth track portion 32114. One end of the first track portion 32111 facing away from the lock head structure 31 and one end of the second track portion 32112 form a first acute angle. The other end of the second track portion 32112 and one end of the third track portion 32113 are connected and form a second acute angle. The ends of the third track portion 32113 and the fourth track portion 32114 facing away from the lock head structure 31 are connected and form a third acute angle. The first locking position 32115 includes the second acute angle, and the first unlocking position 32116 includes the third acute angle.

[0050] Taking the movement of pipe 20 along the first direction X under the action of external force as an example, at this time Figure 1 The self-locking mechanism 30, located above the first connecting assembly 13, limits the first pipe 20. The specific process is as follows: The lock head structure 31 first moves to abut against the sliding latch 322, forming... Figure 3In the state of the lock, the sliding latch 322 slides within the first track 32111 (the sliding direction includes the sub-direction along the first direction X). For ease of understanding, this embodiment designs the sliding track 3211 as a thickened line and shows the internal structure of the lock body 321 that is not visible from the outside.

[0051] When the sliding latch 322 slides to the first acute angle between the first track portion 32111 and the second track portion 32112, the sliding latch 322, guided by the second track portion 32112, enters the second acute angle formed by the connection of the second track portion 32112 and the third track portion 32113, thereby forming as shown in the figure. Figure 4 In the state of being locked, the sliding latch 322 is in the first locking position 32115. At this time, the sliding latch 322 and the pipe 20 can only slide along the guide of the third track 32113 (the sliding direction includes the sub-direction along the first direction X) to a short distance (the second preset distance).

[0052] Subsequently, the sliding latch 322 enters the third acute angle, at which point the sliding latch 322 is located in the first unlock position 32116, thereby allowing the sliding latch 322 to slide out along the fourth track to unlock.

[0053] During the sliding process of the sliding latch 322, the sliding friction between the sliding latch 322 and the sliding track 3211 also has a certain limiting effect on the pipe 20.

[0054] Furthermore, it should be noted that the shape of the sliding track 3211 in this embodiment is not limited to this. For example, the first track portion 32111 and the fourth track portion 32114 can be straight structures along the first direction X. In this case, a sliding track 3211 with an approximate W shape can be formed, and the above-mentioned locking and unlocking process can also be realized.

[0055] In some examples, optionally, in this embodiment, the end of the first track portion 32111 away from the second track portion 32112 is connected to the end of the fourth track portion 32114 away from the third track portion 32113, so that the first track portion, the second track portion 32112, the third track portion 32113 and the fourth track portion 32114 form a closed loop.

[0056] When the sliding latch 322 enters the connection between the fourth track section 32114 (pipeline 20 unlocks) and the first track section 32111, if the pipeline 20 continues to displace along the first direction X, the sliding latch 322 can directly enter the first track section 32111 to continue the above locking and unlocking process. This structural design conforms to the law of reciprocating motion of the pipeline 20 when subjected to external force, thereby achieving better limitation and protection of the pipeline 20.

[0057] Combined again with the appendix Figure 3-6 As shown, in some examples, optionally, the sliding latch 322 includes a slider 3221 and a latching structure 3222. The slider 3221 is slidably connected to the sliding track 3211 and is capable of moving along the first track portion 32111, the second track portion 32112, the third track portion 32113 and the fourth track portion 32114.

[0058] The locking structure 3222 is connected to the side of the sliding member 3221 facing the locking head structure 31. The locking structure 3222 is configured to engage with and disengage from the locking head structure 31. When the locking head structure 31 engages with the locking structure 3222, the locking head structure 31 can drive the locking structure 3222 to move along the second direction Y. When the pipe 20 moves along the second direction Y, the sliding locking structure 322 can also reset and prepare to accept the next engagement with the locking head structure 31. After the locking head structure 31 and the locking structure 3222 are disengaged, the locking structure 3222 will not affect the reset of the pipe 20 and the locking head structure 31 along the second direction Y.

[0059] There are various structural forms that enable the locking structure 3222 to engage and disengage with the locking structure 3222.

[0060] For example, the self-locking mechanism 30 can be designed with a distance sensor, a control component, and a drive component (this embodiment is not shown in the figure). The distance sensor is used to detect the displacement of the lock head structure 31 along the first direction X and the second direction Y. The control component is communicatively connected to both the distance sensor and the drive component. When the distance sensor detects that the lock head structure 31 has moved to a certain displacement along the first direction X, the control component sends a command to the drive component, causing the drive component to drive the latch structure 3222 to move, thereby engaging the lock head structure 31 with the latch structure 3222. Similarly, after the lock head structure 31 has moved to a certain displacement along the second direction Y, the drive component causes the latch structure 3222 to disengage from the lock head structure 31. At this time, the drive component may include a motor, and the latch structure 3222 may include two grippers that are driven to rotate by the motor.

[0061] For example, the self-locking mechanism 30 can be designed as a distance sensor and control circuit with communication connection (this embodiment is not shown in the figure). The latch structure 3222 can be designed to include two electromagnetic components, and the lock head structure 31 can be designed as a magnetically attracted metal component. The distance sensor is used to detect the displacement of the lock head structure 31 along the first direction X and the second direction Y. When the distance sensor detects that the lock head structure 31 has moved to a certain displacement along the first direction X, the control circuit energizes the two electromagnetic components, thereby realizing the engagement of the two electromagnetic components with the lock head structure 31. Similarly, after the lock head structure 31 has moved to a certain displacement along the second direction Y, the control circuit de-energizes the two electromagnetic components, and the two electromagnetic components can release the engagement with the lock head structure 31 under the action of the spring or other reset component.

[0062] The above two methods require the configuration of sensors and circuits, which are complex and costly, and are prone to damage to electronic control components. Therefore, this embodiment provides a locking structure 3222 with purely mechanical action.

[0063] Specifically, the locking structure 3222 includes two latching members 32221, which are respectively hinged to the sliding member 3221 and arranged at intervals along a third direction Z perpendicular to the axial direction of the pipe 20. The two latching members 32221 are configured to move between a closed state and an open state. In the closed state, the two latching members 32221 rotate to engage with the locking head structure 31 respectively. In the open state, the two latching members 32221 rotate to release the engagement with the locking head structure 31.

[0064] Furthermore, the lock body 321 is provided with two rotation limiting parts 3212 (shown as dashed lines in the figure for easy distinction from other structures). The two rotation limiting parts 3212 are arranged at intervals along the third direction Z. Two latching members 32221 are located between the two rotation limiting parts 3212. When the pipe 20 moves the lock head structure 31 and the sliding member 3221 to a certain position of the first track part 32111, the second track part 32112, the third track part 32113, or the fourth track part 32114 (for example, when...), Figure 3 and 4 When the two latching parts 32221 are in the closed position, the two rotation limit parts 3212 abut against the two latching parts 32221 one by one, so that the two latching parts 32221 rotate to engage with the lock head structure 31 respectively.

[0065] When the lock head structure 31 drives the sliding member 3221 to a certain position of the first track part 32111 or the fourth track part 32114 (e.g. Figure 6As shown), the two latching parts 32221 are reset to the unfolded state, and the two rotation limiting parts 3212 and the two latching parts 32221 form an axial gap along the pipe 20, so that the two latching parts 32221 rotate to release the locking head structure 31.

[0066] The reset of the latch 32221 can be achieved by installing a torsion spring (not shown in the figure) at the connection between the latch 32221 and the slider 3221. When the latch 32221 is rotated from the unfolded state to the closed state, the torsion spring is compressed. When the latch 32221 is rotated from the closed state to the unfolded state, the torsion spring provides rotational force.

[0067] In some examples, optionally, the slider 3221 of this embodiment includes a swing rod 32211 and a sliding frame 32212. One end of the swing rod 32211 is slidably connected to the sliding track 3211, and the other end of the swing rod 32211 is hinged to the sliding frame 32212. The locking structure 3222 is installed on the sliding frame 32212.

[0068] Furthermore, in this embodiment, the end of the swing rod 32211 connected to the sliding rail 3211 is provided with a rotatable rotating part 322111. The rotating part 322111 is slidably connected to the sliding rail 3211, and the rotation axis of the rotating part 322111 is perpendicular to the length direction of the load-bearing beam 11 and the axis of the pipe 20, respectively.

[0069] The reason for designing the slider 3221 to include a swing rod 32211 and a sliding frame 32212 is that, in some embodiments, the sliding track 3211 is located at an angle to the first direction X and the second direction Y, or the sliding track 3211 is located in a curved or arc-shaped position. Therefore, by utilizing the rotation of the rotating part 322111 of the swing rod 32211 and the rotation of the swing rod 32211 on the sliding frame 32212, the slider 3221 only needs to move along the first direction X and the second direction Y, without the slider 3221 needing to move in other directions, thus not affecting the engagement or disengagement of the locking head structure 31 and the latching structure 3222 on the slider 3221.

[0070] The above description is merely a preferred embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in the present invention should be included within the scope of protection of the present invention. Therefore, the scope of protection of the present invention should be determined by the scope of the claims.
