Description

Technical Field

[0001] This invention relates to the field of installation tool technology, and in particular to an installation fastener. Background Technology

[0002] Currently, fasteners are widely used in the production and installation of panel furniture to connect and install the panels, ensuring reliable connections between them. However, conventional fasteners are complex to install, have numerous accessories, and require drilling or grooving on the exposed surfaces of the furniture, which affects its aesthetic appearance.

[0003] As people's living standards improve, their demands for the aesthetics and practicality of furniture are increasing. This has led to the emergence of two-in-one concealed fasteners on the market. These fasteners can be hidden within the mounting panels, making the installed furniture more aesthetically pleasing and achieving a seamless, hole-free finish. However, current concealed fasteners are difficult to remove after installation and have a complex structure, making them inconvenient for users. Summary of the Invention

[0004] Therefore, it is necessary to provide a simple and easy-to-disassemble installation fastener to address the problems of complex structure and inconvenient disassembly of current concealed fasteners.

[0005] A mounting fastener for connecting a first board and a second board of furniture panels, the mounting fastener comprising:

[0006] A connecting assembly, disposed in the first plate, includes a mounting sleeve and a locking member. The mounting sleeve has a mating hole extending in the axial direction and a locking groove disposed in the radial direction. The locking groove communicates with the mating hole. The locking member is disposed in the locking groove and is movable radially along the locking groove.

[0007] The mounting rod has one end disposed in the second plate, and the other end of the mounting rod can extend into the mating hole and be locked by the locking member. When the locking member moves away from the mounting rod in the radial direction, the mounting rod can move out of the mating hole.

[0008] In one embodiment, the locking element includes a locking block and a reset element, the locking block being installed in the locking groove, the reset element connecting the locking block to the mounting sleeve, and the elastic force of the reset element causing the locking block to be at least partially located in the mating hole.

[0009] In one embodiment, the reset member includes an elastic ring, the outer periphery of the locking block has a first limiting groove, the outer periphery of the mounting sleeve has a second limiting groove communicating with the first limiting groove, and the elastic ring is installed in the first limiting groove and the second limiting groove.

[0010] In one embodiment, the inner wall of the locking block has an arcuate groove for contacting the mating hole;

[0011] The locking block also has a flared groove at its end, which is located at the end of the arc-shaped groove and is used to guide the mounting rod through the arc-shaped groove to extend out.

[0012] In one embodiment, the mounting sleeve includes a first mounting section and a second mounting section. The outer diameter of the first mounting section is larger than the outer diameter of the second mounting section. The first mounting section has the locking groove, and the edge of the locking groove has a preset distance from the end of the first mounting section to limit the axial position of the locking member.

[0013] In one embodiment, the end of the second mounting segment away from the first mounting segment has a mating portion, the extension of which is located in the locking groove, and the mating portion is used to engage with the positioning portion of the tightening tool.

[0014] In one embodiment, the thickness of the second mounting segment gradually increases along the axial direction from the second mounting segment to the first mounting segment.

[0015] In one embodiment, the mounting fastener further includes a mounting sleeve, the outer surface of which has at least a portion of external threads for mounting in the connecting hole of the first plate, and the mounting sleeve is interference-fitted into the mounting sleeve;

[0016] The mounting sleeve has a first through hole and a second through hole. The first through hole communicates with the second through hole and extends through the mounting sleeve. The inner diameter of the second through hole is smaller than the inner diameter of the first through hole. The first through hole is used to install the first mounting section, and the second through hole is used to install the second mounting section. The end of the second through hole is connected to a tightening groove, which is used to cooperate with the tightening section of a tightening tool.

[0017] In one embodiment, the mounting rod includes a limiting section, a connecting section, and a fixing section connected in sequence. The fixing section is used to install in the second plate. After the limiting section extends into the mating hole, the limiting section can cooperate with the locking member to restrict the axial movement of the mounting rod.

[0018] In one embodiment, the limiting segment has a recess for mounting the locking block, and the inner wall of the recess can abut against the locking block;

[0019] The end of the limiting segment is pointed.

[0020] By adopting the above technical solution, the present invention has at least the following technical effects:

[0021] The mounting fastener of this invention comprises a mounting sleeve for the connecting component housed in a first plate, a locking member installed radially in a locking hole of the mounting sleeve, and a mounting rod housed in a second plate. When the first and second plates need to be joined, the mounting rod is installed into the mating hole of the mounting sleeve, allowing the locking member to abut against the mounting rod, restricting its movement out of the mating hole and ensuring a reliable connection between the first and second plates. When the plates need to be disassembled, an adsorption member is used to attract the locking member, causing it to move radially away from the mounting rod. This allows the mounting rod to move out of the mating hole, enabling the disassembly of the first and second plates. This mounting fastener has a simple structure, using the radial movement of the locking member to lock and unlock the mounting rod, thereby facilitating the installation and disassembly of the first and second plates. This makes it convenient for quick assembly and disassembly of the first and second plates and user-friendly. Attached Figure Description

[0033] See Figures 1 to 4 This invention provides a mounting fastener 100. The mounting fastener 100 is used to connect furniture panels, enabling splicing and joining of the panels. Furthermore, the mounting fastener 100 is located inside the furniture panel and is not exposed, preventing gaps after splicing and ensuring the aesthetic appearance of the joined furniture panels. Of course, in other embodiments of this invention, the mounting fastener 100 can also be used to connect other two structural components.

[0034] Understandably, as people's living standards improve, their demands for the aesthetics and practicality of furniture are increasing, often leading to the use of concealed fasteners to connect the panels. However, current concealed fasteners, once installed, make it difficult to disassemble the panels, and their complex structure makes them inconvenient for users.

[0035] Therefore, the present invention provides a novel mounting fastener 100. The mounting fastener 100 has a simple structure, facilitating its installation. Furthermore, it is easy to disassemble, requiring only the use of an external adsorption component such as a magnet for quick removal, making it convenient for users. The specific structure of the mounting fastener 100 is described in detail below.

[0036] See Figures 1 to 4In one embodiment, the mounting fastener 100 is used to connect a first board and a second board of furniture panels. The mounting fastener 100 includes a connecting assembly 110 and a mounting rod 120. The connecting assembly 110 is disposed in the first board and includes a mounting sleeve 111 and a locking member 112. The mounting sleeve 111 has a mating hole 1111 extending in the axial direction and a locking groove 1112 disposed in the radial direction. The locking groove 1112 communicates with the mating hole 1111, and the locking member 112 is disposed in the locking groove 1112 and can move radially along the locking groove 1112. The second mounting rod 120 has one end disposed in the second board, and the other end can extend into the mating hole 1111 and be locked by the locking member 112. When the locking member 112 moves radially away from the mounting rod 120, the mounting rod 120 can move out of the mating hole 1111.

[0037] The mounting fastener 100 enables the splicing and connection of furniture panels. Taking a furniture panel consisting of a first panel and a second panel as an example, one end of the mounting fastener 100 is located at the end of the first panel, and the other end is located at the end of the second panel. By engaging the mounting fasteners 100 on the first panel and the second panel, the splicing and connection of the first and second panels can be achieved. Furthermore, through the cooperation of the mounting components, the end of the first panel can contact the end of the second panel, achieving a seamless connection between the first and second panels and ensuring the aesthetic appeal of the joined furniture panels.

[0038] Of course, in other embodiments of the present invention, when more boards need to be connected, multiple boards can be spliced ​​and connected by setting the mounting fastener 100 to realize the assembly of furniture boards.

[0039] The mounting assembly includes a connecting component 110 and a mounting rod 120. The first plate has a connecting hole at one end, and the connecting component 110 is screwed into this hole. The second plate also has an inner hole at one end, and one end of the mounting rod 120 is fixedly installed in this inner hole. When the first and second plates are joined together, the other end of the mounting rod 120 can extend into the connecting component 110, locking the mounting rod 120 and restricting its axial movement. When it is necessary to disassemble the first and second mounting plates, the connecting component 110 is unlocked, allowing the mounting rod 120 to be removed.

[0040] See Figures 1 to 4The connecting assembly 110 includes a mounting sleeve 111 and a locking member 112. The mounting sleeve 111 has a mating hole 1111 extending in the axial direction, which allows the mounting rod 120 to be installed. The mounting sleeve 111 also has a locking groove 1112 in the radial direction, which communicates with the mating hole 1111. The locking member 112 can be installed in the locking groove 1112. The locking member 112 can move radially in the locking groove 1112 to lock or unlock the mounting rod 120.

[0041] The locking member 112 has a locked position and an unlocked position. When the locking member 112 moves radially in the locking groove 1112, it can move between the locked position and the unlocked position. When the locking member 112 is in the locked position, it abuts against the mounting rod 120 in the mating hole 1111, restricting the axial movement of the mounting rod 120. When the locking member 112 is in the unlocked position, it disengages from the mounting rod 120, allowing the mounting rod 120 to move axially and exit the mating hole 1111.

[0042] Furthermore, the locking member 112 is normally in the locked position. During the installation of the mounting rod 120 into the mating hole 1111, the mounting rod 120 can push up the locking member 112, causing the locking member 112 to move from the locked position to the unlocked position. After the mounting rod 120 is installed in the mating hole 1111, the locking member 112 moves downward to reset, moving from the unlocked position to the locked position. At this time, the locking member 112 locks the mounting rod 120, realizing the connection between the first plate and the second plate.

[0043] When it is necessary to disassemble the first and second plates, the locking member 112 is controlled to move upward, so that the locking member 112 disengages from the mounting rod 120. The locking member 112 moves from the locked position to the unlocked position, and the mounting rod 120 can be removed from the mating hole 1111. It is understood that the upward movement of the locking member 112 during unlocking can be controlled by an adsorption member. The adsorption member can attract the locking member 112, causing the locking member 112 to move upward to disengage from the mounting rod 120, thereby unlocking the mounting rod 120. Optionally, the adsorption member is a magnet. Of course, in other embodiments of the present invention, the locking member 112 may also be other components capable of adsorption or structures that control the upward movement of the locking member 112.

[0044] The mounting fastener 100 in the above embodiment locks and unlocks the mounting rod 120 through the radial movement of the locking member 112, thereby enabling the installation and disassembly of the first plate and the second plate. This effectively solves the problems of complex structure and inconvenient disassembly when connecting and installing plates with concealed fasteners, facilitating the quick assembly and disassembly of the first plate and the second plate, and making it convenient for users.

[0045] In one embodiment, the locking member 112 includes a locking block 1121 and a reset member 1122. The locking block 1121 is installed in the locking groove 1112, and the reset member 1122 connects the locking block 1121 and the mounting sleeve 111. The elastic force of the reset member 1122 causes the locking block 1121 to be at least partially located in the mating hole 1111.

[0046] The locking block 1121 is the main structure for locking and unlocking the locking member 112. The locking block 1121 is installed in the locking groove 1112 and can move radially along the locking groove 1112. The reset member 1122 has an elastic force and can connect the locking block 1121 to the mounting sleeve 111. After the locking block 1121 is installed in the locking groove 1112, the elastic force generated by the reset member 1122 allows the locking member 112 to fit against the mounting sleeve 111, ensuring that the locking block 1121 is in the locked position.

[0047] When the locking member 112 is unlocked, the force applied by the mounting rod 120 to the locking block 1121 is greater than the elastic force generated by the reset member 1122. At this time, the mounting rod 120 can lift the locking block 1121, causing the locking block 1121 to move from the locked position to the unlocked position, which facilitates the installation of the mounting rod 120. After the mounting rod 120 moves to the designated position, the force applied by the mounting rod 120 to the locking block 1121 is less than the elastic force of the reset member 1122. Therefore, the elastic force of the reset member 1122 can drive the locking block 1121 to reset, causing the locking block 1121 to move from the unlocked position to the locked position. The mounting rod 120 is locked by the cooperation of the elastic force of the reset member 1122 and the locking block 1121.

[0048] During unlocking, the adsorption force of the suction member on the locking block 1121 is greater than the elastic force generated by the reset member 1122. At this time, the suction member can overcome the elastic force of the reset member 1122 and drive the locking block 1121 upward to the unlock position. Then, the locking block 1121 disengages from the mounting rod 120, and the mounting rod 120 can move out of the mating hole 1111, realizing the disassembly of the first plate and the second plate. After disassembly, the locking block 1121 is removed, and the locking block 1121 is no longer subject to the suction force. The elastic force of the reset member 1122 causes the locking block 1121 to reset to the locked position.

[0049] Optionally, the length of the locking block 1121 is slightly less than the axial length of the locking groove 1112. That is, there is a certain gap between the locking element 112 and the inner wall of the locking groove 1112. This facilitates the radial movement of the locking block 1121 within the locking groove 1112, preventing interference between the locking element 112 and the inner wall of the locking groove 1112. Furthermore, the inner wall of the locking groove 1112 also limits the locking block 1121, restricting its axial movement and ensuring that the mounting rod 120 is reliably installed in the mating hole 1111. This prevents gaps and wobbling between the first and second plates, ensuring the reliability of their connection.

[0050] In one embodiment, the reset member 1122 includes an elastic ring. That is, the locking block 1121 switches between a locked position and an unlocked position by cooperating with the elastic ring. Specifically, after the locking block 1121 is disposed in the locking groove 1112, the elastic ring is simultaneously sleeved on the outside of both the mounting sleeve 111 and the locking block 1121. The elastic ring restricts the position of the locking block 1121, ensuring that the locking block 1121 is in the locked position. Furthermore, when the external force on the locking block 1121 exceeds the elastic force of the elastic ring, the locking block 1121 moves away from the mating hole 1111, allowing the mounting rod 120 to be installed in or removed from the mating hole 1111. When the locking block 1121 is not subjected to external force or the external force is less than the elastic force of the elastic ring, the elastic ring can move the locking block 1121 to the locked position. Optionally, the elastic ring is made of rubber or other elastic materials.

[0051] In one embodiment, the outer periphery of the locking block 1121 has a first limiting groove 11211, and the outer periphery of the mounting sleeve 111 has a second limiting groove 1113 communicating with the first limiting groove 11211. The elastic ring is installed in the first limiting groove 11211 and the second limiting groove 1113. The first limiting groove 11211 and the second limiting groove 1113 can restrict the position of the elastic ring, prevent the elastic ring from slipping out, and fix the elastic ring in the position of the locking block 1121, ensuring that the elastic ring can accurately drive the locking block 1121 to reset.

[0052] Optionally, the depth of the first limiting groove 11211 is greater than or equal to the thickness of the elastic ring. Alternatively, the depth of the first limiting groove 11211 can be less than the thickness of the elastic ring. The depth of the first limiting groove 11211 is the same as the depth of the second limiting groove 1113. Optionally, the width of the first limiting groove 11211 is slightly greater than the width of the elastic ring.

[0053] In one embodiment, the reset member 1122 includes a compression spring, which connects the inner wall of the locking groove 1112 and the edge of the locking block 1121. That is, the locking block 1121 switches between a locked position and an unlocked position through its cooperation with the compression spring. Specifically, after the locking block 1121 is positioned in the locking groove 1112, the compression spring simultaneously connects the mounting sleeve 111 and the locking block 1121. The elastic force of the compression spring restricts the position of the locking block 1121, thus placing it in the locked position. Furthermore, when the external force on the locking block 1121 exceeds the elastic force of the compression spring, the locking block 1121 moves away from the mating hole 1111, allowing the mounting rod 120 to be installed in or removed from the mating hole 1111. When the locking block 1121 is not subjected to external force or the external force is less than the elastic force of the compression spring, the compression spring can move the locking block 1121 to the locked position.

[0054] In one embodiment, the inner wall of the locking block 1121 has an arc-shaped groove for contacting the mating hole 1111. That is, the cross-section of the locking block 1121 facing the mating hole 1111 is arc-shaped and extends axially. After the locking groove 1112 is formed on the mounting sleeve 111, a notch is formed in the mating hole 1111 at the location of the locking groove 1112, and the locking block 1121 is installed in the notch. To ensure the limiting effect of the locking block 1121 on the mounting rod 120, an arc-shaped groove is provided on the surface of the locking block 1121 located in the mating hole 1111. The arc-shaped groove can mate with the mating hole 1111 at the notch to form a complete circular hole. In this way, the inner wall of the arc-shaped groove can fit against the outer wall of the mounting rod 120, restricting the axial movement of the mounting rod 120.

[0055] In one embodiment, the locking block 1121 further has a flared groove at its end, which is disposed at the end of the arc-shaped groove to guide the mounting rod 120 through the arc-shaped groove and extend outward. The flared groove is located at one end of the arc-shaped section and serves as a guide, allowing the mounting rod 120 to enter and extend into the arc-shaped groove through the flared groove, facilitating the connection between the mounting rod 120 and the connecting assembly 110. The dimension of the end of the flared groove connected to the arc-shaped groove is smaller than the dimension of the end of the flared groove furthest from the arc-shaped groove, and the dimension of the flared groove gradually increases along the axial direction, forming a structure similar to a flared mouth, which facilitates the installation of the mounting rod 120.

[0056] In one embodiment, the mounting sleeve 111 includes a first mounting section 1114 and a second mounting section 1115. The outer diameter of the first mounting section 1114 is larger than the outer diameter of the second mounting section 1115. The first mounting section 1114 has the locking groove 1112, and the edge of the locking groove 1112 is spaced at a predetermined distance from the end of the first mounting section 1114 to limit the axial position of the locking member 112.

[0057] The first mounting section 1114 and the second mounting section 1115 are connected sequentially to form a complete mounting sleeve 111. The first mounting section 1114 and the second mounting section 1115 are both hollow structures, and their hollow structures communicate to form the mating hole 1111 of the mounting sleeve 111. Furthermore, a locking groove 1112 is provided on the first mounting section 1114 for mounting a locking block 1121. The outer diameter of the first mounting section 1114 is larger than the outer diameter of the second mounting section 1115. In other words, the first mounting section 1114 and the second mounting section 1115 are stepped cylinders. This facilitates the installation of the first mounting section 1114 and the second mounting section 1115 into the first plate.

[0058] Optionally, the first mounting section 1114 and the second mounting section 1115 are an integral structure. Optionally, the locking block 1121 is arc-shaped. That is, the outer contour of the locking block 1121 is a part of the cross-section of the first mounting section 1114.

[0059] In one embodiment, the mounting fastener 100 further includes a mounting sleeve 130, the outer surface of which at least partially has external threads for mounting in the connecting hole of the first plate. The mounting sleeve 111 is interference-fitted into the mounting sleeve 130. The mounting sleeve 130 has a first through hole 131 and a second through hole 132, the first through hole 131 communicating with and penetrating the mounting sleeve 130. The inner diameter of the second through hole 132 is smaller than the inner diameter of the first through hole 131. The first through hole 131 is used to install the first mounting section 1114, and the second through hole 132 is used to install the second mounting section 1115. The end of the second through hole 132 communicates with a tightening groove, which is used to cooperate with the tightening section 210 of the tightening tool 200.

[0060] The mounting sleeve 130 provides protection, and it houses the connecting assembly 110. The connecting assembly 110 is installed into the first plate through the mounting sleeve 130. Specifically, the mounting sleeve 111 is interference-fitted into the mounting sleeve 130, forming a single integral structure with the mounting sleeve 111, ensuring that the mounting sleeve 111 does not rotate relative to the mounting sleeve 130. Thus, when the mounting sleeve 130 is installed into the first plate, the mounting sleeve 111 is installed into the mounting sleeve 130, with one end of the mounting sleeve 130 placed in the connecting hole. Rotating the mounting sleeve 130 causes the mounting sleeve 111 to rotate synchronously, thus installing the mounting sleeve 111 into the first plate. It is understood that the mounting sleeve 130 is installed into the connecting hole of the first plate using a self-tapping method.

[0061] Optionally, the mounting sleeve 130 and the mounting socket 111 can be installed by tapping to ensure that the mounting socket 111 is accurately installed into the mounting sleeve 130. Optionally, the mounting sleeve 130 can be installed into the first plate by electric means or by manual means.

[0062] The mounting sleeve 130 has a first through hole 131 and a second through hole 132 inside, which connect and extend axially through the entire mounting sleeve 130. The outer diameter of the first through hole 131 is larger than the outer diameter of the second through hole 132. The first mounting section 1114 can be installed in the first through hole 131, and the second mounting section 1115 can be installed in the second through hole 132. The mounting sleeve 111 is fixed by the cooperation between the second through hole 132 and the second mounting section 1115.

[0063] Furthermore, the mounting sleeve 130 also has a tightening groove, which is located at the end of the second through hole 132 away from the first through hole 131. This tightening groove can cooperate with the tightening section 210 of the tightening tool 200. After the tightening section 210 is installed into the tightening groove, the outer wall of the tightening section 210 can fit against the inner wall of the tightening groove. When the tightening tool 200 rotates, it can drive the tightening section 210 to rotate, which in turn drives the tightening groove to rotate. The rotation of the tightening groove drives the mounting sleeve 130 to rotate, allowing the mounting sleeve 130 to be screwed into the first plate. In this way, the seamless connection between the first plate and the second plate can be achieved through the cooperation of the connecting component 110 and the mounting rod 120.

[0064] Optionally, the inner wall of the tightening groove is polygonal, and correspondingly, the outer wall of the tightening section 210 is also polygonal. The engagement between the tightening section 210 and the tightening groove drives the mounting sleeve 130 to rotate. For example, the tightening section 210 is an outer hexagon, and the tightening groove is an inner hexagon. Of course, in other embodiments of the invention, a recessed area can be provided in the tightening groove to engage with the protrusion of the tightening section 210.

[0065] In one embodiment, the end of the second mounting segment 1115 away from the first mounting segment 1114 has a mating portion 11151, the extension of which is located in the locking groove 1112, and the mating portion 11151 is used to engage with the positioning portion 220 of the tightening tool 200.

[0066] The mating part 11151 is used to position the locking member 112, ensuring that the locking member 112 is in a preset position after installation, facilitating its removal via the suction member. This preset position is directly above the first plate. When the mounting sleeve 130 drives the mounting sleeve 111 and the locking member 112 into the first plate, the locking member 112 is positioned inside the first plate. When the locking member 112 is in the preset position, the suction member is moved directly above the first plate, allowing it to unlock the locking member 112. If the locking member 112 deviates from the preset position, moving the suction member into the preset position will result in a suction force on the locking member 112 that is less than the elastic force generated by the reset member 1122, preventing the locking member 112 from unlocking.

[0067] Therefore, when installing the mounting sleeve 130 into the first plate, it is necessary to ensure that the locking member 112 is in the preset position. Understandably, the number of rotations of the mounting sleeve 130 into the first plate is consistent with the distance it moves. Therefore, when placing the mounting sleeve 130 at the end of the connecting hole in the first plate, with the locking member 112 facing a certain direction, rotating the mounting sleeve 130 until it is fully installed into the first plate will ensure that the locking member 112 is in the preset position, facilitating the installation and removal of the mounting rod 120.

[0068] It is worth noting that the preset position is not limited to the top of the first plate; it can also be any position where other adsorption components can unlock the locking member 112. Assuming that installation can be completed after rotating the mounting sleeve 130 nine times, when the mounting sleeve 130 is placed at the end of the connecting hole in the first plate, with the locking member 112 facing the preset position, after rotating nine times, the locking member 112 will be in the preset position. Of course, in other embodiments of the present invention, the mounting sleeve 130 can also be rotated a different number of times to achieve installation.

[0069] Since the locking member 112 is installed onto the mounting sleeve 130, and the mounting sleeve 130 is installed onto the first plate, the user cannot easily know the installation position of the locking member 112, and therefore cannot determine whether the locking member 112 has reached the preset position. Therefore, the mounting fastener 100 of the present invention provides a mating part 11151 at the end of the second mounting section 1115 of the mounting sleeve 111. After the mating part 11151 is connected to the positioning part 220 of the tightening tool 200, the user can know the installation position of the locking member 112 through the positioning part 220 of the tightening tool 200, ensuring that the locking member 112 is in the preset position after installation, facilitating the disassembly of the mounting fastener 100.

[0070] Optionally, the central axis of the mating portion 11151 coincides with the central axis of the locking groove 1112. This allows the mating portion 11151 to indicate the installation position of the locking member 112 through the engagement of the tightening tool 200. Alternatively, in other embodiments of the invention, the central axis of the mating portion 11151 may be located within the locking groove 1112. This also allows the mating portion 11151 to indicate the installation position of the locking member 112 through the engagement of the tightening tool 200. Optionally, the mating portion 11151 is a mating groove extending axially to the end of the second mounting section 1115. Alternatively, in other embodiments of the invention, the mating portion 11151 may be any other structure capable of engaging with the positioning portion 220 for positioning.

[0071] In one embodiment, the thickness of the second mounting segment 1115 gradually increases along the axial direction from the second mounting segment 1115 towards the first mounting segment 1114. That is, the dimension of the connection portion between the second mounting segment 1115 and the first mounting segment 1114 is larger than the dimensions of the remaining portions of the second mounting segment 1115. This ensures that when the second mounting segment 1115 mates with the second through hole 132 of the mounting sleeve 130, the second mounting segment 1115 is reliably fixed in the second mounting hole, preventing axial movement of the second mounting sleeve 111.

[0072] Optionally, along the axial direction, from the mating part 11151 to the connection between the second mounting section 1115 and the first mounting section 1114, the thickness of the second mounting section 1115 gradually increases. That is, the mounting sleeve 111 has a certain taper on the second mounting section 1115 to ensure reliable installation of the mounting sleeve 111.

[0073] Furthermore, this design with increased thickness can also reduce the connection gap between the first and second plates. Understandably, when there is a connection gap between the first and second plates, striking the second plate towards the first plate causes the mounting rod 120 to move towards the first plate. This movement, in turn, allows the mounting rod 120 to move via the locking element 112, thus reducing the connection gap between the first and second mounting plates. During this process, the increased thickness design ensures a reliable fit between the second mounting section 1115 and the second through hole 132, preventing the mounting sleeve 111 from wobbling within the mounting sleeve 130.

[0074] In one embodiment, the mounting rod 120 includes a limiting section 121, a connecting section 122, and a fixing section 123 connected in sequence. The fixing section 123 is used to install in the second plate. After the limiting section 121 extends into the mating hole 1111, the limiting section 121 can cooperate with the locking member 112 to restrict the axial movement of the mounting rod 120.

[0075] Mounting rod 120 is a stepped rod. One end of connecting section 122 is connected to fixing section 123, and the other end of connecting section 122 is connected to limiting section 121. Fixing section 123 is fixedly installed in the inner hole of the second plate, while limiting section 121 and connecting section 122 extend out of the second plate. When the second plate is connected to the first plate, limiting section 121 gradually extends into mounting sleeve 111 in the first plate along mating hole 1111, and locks the mounting rod 120 by engaging with locking member 112, thereby achieving the connection between the first plate and the second plate.

[0076] When the first plate and the second plate are disassembled, the adsorption component adsorbs the locking component 112 on the first plate, causing the locking component 112 to move to the unlock position. The limiting segment 121 can be removed from the locking component 112, and then the mounting sleeve 111 can be removed, thus realizing the disassembly of the first plate and the second plate.

[0077] Optionally, the limiting section 121, the connecting section 122, and the fixing section 123 are an integral structure. Optionally, the fixing section 123 has external threads, and the inner hole of the second plate has internal threads. The fixing section 123 and the second plate are fixedly connected through the cooperation of the internal and external threads. Of course, in other embodiments of the present invention, the fixing section 123 and the second plate can also adopt other forms of connection, as long as the connection is reliable.

[0078] In one embodiment, the limiting segment 121 has a recess 1211 for mounting the locking block 1121. The inner wall of the recess 1211 can abut against the locking block 1121. The recess 1211 is recessed into the surface of the limiting segment 121. After the locking block 1121 is engaged with the mounting rod 120, the locking block 1121 is located in the recess 1211. The inner wall of the recess 1211 can abut against the end of the locking block 1121. The axial movement of the locking block 1121 is restricted by the inner wall of the recess 1211. At the same time, the locking block 1121 can also restrict the axial movement of the mounting rod 120, thereby locking the mounting rod 120.

[0079] In one embodiment, the end of the limiting segment 121 is a pointed tip 1212. This reduces the installation resistance of the mounting rod 120, making it easier for the mounting rod 120 to be installed into the mating hole 1111.

[0080] In one embodiment, the locking member 112 is made of a magnetic material, while the mounting sleeve 130, mounting sleeve 111, reset member 1122, and mounting rod 120 are made of non-magnetic materials. This allows the adsorption member to only adsorb the locking member 112, enabling it to move from the locked position to the unlocked position without moving other components, thus ensuring the reliability of the locking member 112's unlocking.

[0081] In use, the mounting fastener 100 of the present invention involves installing the locking block 1121 in the locking groove 1112 of the mounting sleeve 111, and connecting the locking block 1121 and the mounting sleeve 111 via the reset member 1122, thereby locking the locking block 1121 in a locked position. Subsequently, the mounting sleeve 111 is installed in the mounting sleeve 130, ensuring a reliable connection between the two. Using a tightening tool 200 or similar tool, one end of the mounting sleeve 130 is placed in the connecting hole of the first plate, and the locking member 112 is oriented towards a preset position through the engagement of the mating part 11151 and the positioning part 220. The mounting sleeve 130 is then rotated using the tightening tool 200 or similar means, causing it to screw into the first plate and oriented the locking block 1121 towards the preset position.

[0082] The mounting rod 120 is installed into the second plate through the fixing section 123. When connecting the first plate and the second plate, the limiting section 121 of the mounting rod 120 is installed into the mating hole 1111 and moves along the mating hole 1111. When the limiting section 121 of the mounting rod 120 contacts the locking block 1121, the limiting section 121 can push up the locking block 1121, so that the locking block 1121 overcomes the elastic force of the reset member 1122 and moves from the locked position to the unlocked position, and the limiting section 121 continues to move along the mating hole 1111. When the limiting segment 121 does not apply force to the locking block 1121, or the force is small, the reset member 1122 can drive the locking block 1121 to reset from the unlocked position to the locked position. The locking block 1121 can be locked in the recess 1211. The axial movement of the mounting rod 120 is restricted by the cooperation between the locking block 1121 and the recess 1211, thereby locking the mounting rod 120 and connecting the first plate and the second plate.

[0083] When it is necessary to disassemble the first and second plates, the adsorption component, such as a magnet, is moved to a preset position on the first plate, and the locking block 1121 is adsorbed by the adsorption component. At this time, the adsorption force generated by the adsorption component on the locking block 1121 is greater than the elastic force applied by the reset component 1122 to the locking block 1121. Under the action of the adsorption force, the locking block 1121 moves from the locked position to the unlocked position. Then, the second plate is pulled outward, and the second plate can drive the mounting rod 120 to move out of the mating hole 1111, realizing the disassembly of the first and second plates. After the adsorption component is removed, the elastic force of the reset component 1122 can drive the locking block 1121 to reset from the unlocked position to the locked position.

[0084] The mounting fastener 100 of this invention, by locking or unlocking the mounting rod 120 through the locking member 112, effectively solves the problems of complex structure and inconvenient disassembly when connecting and installing plates with current concealed fasteners, enabling quick installation and disassembly of the first plate and the second plate, making it convenient for users. At the same time, the mounting fastener 100 has a simple structure, is quick and convenient to install, shortens installation time, and improves assembly efficiency.
