Description

Technical Field

[0001] The present invention relates to the technical field of installation tools, in particular to a tightening tool. Background Art

[0002] Currently, during the production and installation of panel furniture, fasteners are often used extensively to connect the panels and ensure reliable connections. However, these conventional fasteners are complex to install, require numerous components, and require drilling or slotting on the visible surfaces of the furniture, which can negatively impact its aesthetic appearance.

[0003] As people's living standards improve, the demand for the beauty and practicality of furniture is getting higher and higher. Two-in-one invisible fasteners have appeared on the market. The invisible fasteners include a first part and a second part. The first part is set in one mounting plate, and the second part is installed in another mounting plate. The connection between the two mounting plates is achieved through the cooperation of the first part and the second part. In addition, the invisible fastener can be hidden in the mounting plate, making the installed furniture more beautiful and seamless without exposed holes. Usually, invisible fasteners are installed in the mounting plate manually or electrically, and they must be installed in a preset position to facilitate the removal of the invisible fasteners. However, the current manual or electric installation methods cannot guarantee the effective installation of the invisible fasteners, which in turn affects the removal of the invisible fasteners and is inconvenient to use. Summary of the Invention

[0004] Based on this, it is necessary to provide a tightening tool that can ensure that the locking part is installed in a preset position to address the problem that the current invisible fastener is not accurately positioned after being installed on the mounting plate, which affects the removal of the invisible fastener.

[0005] A tightening tool for installing a mounting fastener in a furniture plate through an installation sleeve, the tightening tool comprising:

[0006] A mounting assembly, one end of which contacts the mounting sleeve in the mounting sleeve and the other end of which is connected to an operating tool; and

[0007] A positioning component, one end of which is telescopically arranged on the mounting component, and the other end of which is capable of extending into the mounting fastener, and the positioning component is capable of indicating the installation position of the locking member in the mounting fastener.

[0008] In one embodiment, the mounting assembly includes a mounting body and a connecting rod, the mounting body having a first end and a second end arranged opposite to each other in an axial direction, the first end having a mounting hole extending in the axial direction, the mounting hole being used for telescopically mounting the positioning assembly, the second end being a connecting rod extending in the axial direction, the connecting rod being used to connect the operating tool.

[0009] In one embodiment, the installation body also includes a hollow tightening section, which is arranged at the first end of the installation body and cooperates with the tightening groove of the installation sleeve. The tightening section drives the installation sleeve to be screwed into the furniture panel through the inner wall of the tightening groove.

[0010] In one embodiment, the positioning assembly includes a telescopic component and an indicating component. The telescopic component can be telescopically arranged in the mounting hole. The indicating component can be rotatably mounted on the mounting body and connected to the telescopic component. The indicating component can be telescopic and rotated with the telescopic component.

[0011] In one embodiment, a surface of the mounting body has a avoidance groove, the avoidance groove extends along the circumferential direction and the axial direction of the mounting body and communicates with the mounting hole, and the indicating component passes through the avoidance groove to connect with the telescopic component;

[0012] The central angle of the avoidance groove ranges from 60° to 180°.

[0013] In one embodiment, the telescopic component includes a positioning rod and an elastic member, the elastic member is arranged in the mounting hole, the positioning rod is installed in the mounting hole and abuts against the elastic member, and the positioning rod can compress the elastic member or the elastic force of the elastic member to reset the positioning rod.

[0014] In one embodiment, the indicating component includes a fixing piece, the positioning rod has a fixing hole in the radial direction, the fixing piece passes through the avoidance groove and is installed in the fixing hole of the positioning rod, and the fixing piece can move with the positioning rod in the avoidance groove.

[0015] In one embodiment, one end of the positioning rod has a positioning portion, and the positioning portion is engaged with the mating portion in the mounting fastener. The positioning portion and the mounting hole are arranged along the same axial direction to indicate the installation position of the locking member.

[0016] In one embodiment, the indicating component further includes a sliding sleeve, which can be slidably mounted on the outer side of the mounting body. The sliding sleeve has a through hole provided therethrough, and the fixing member can be installed in the fixing hole of the positioning rod by passing through the through hole and the avoidance groove.

[0017] In one embodiment, the mounting assembly further includes a mounting boss, which is disposed at the first end of the mounting body and located between the mounting body and the tightening section. The outer diameter of the mounting boss is smaller than the outer diameter of the mounting body and larger than the outer diameter of the tightening section. The mounting boss is used to screw the mounting sleeve into the interior of the furniture panel.

[0018] After adopting the above technical solution, the present invention has at least the following technical effects:

[0019] In the tightening tool of the present invention, one end of the positioning assembly can be telescopically mounted on the mounting assembly, and the other end of the positioning assembly can be detachably mounted on the mounting fastener. When the tightening tool is used, the other end of the positioning assembly is installed in the mounting fastener, and the mounting fastener is installed on the furniture plate through the mounting sleeve, and one end of the mounting assembly is brought into contact with the mounting sleeve, and then the operating tool is installed on the other end of the mounting assembly. When the operating tool rotates, it can drive the mounting sleeve and the mounting fastener therein to rotate through the mounting assembly, so that the mounting sleeve and the mounting space therein can be screwed into the furniture plate, and the installation position of the locking member in the mounting fastener is known through the positioning assembly, so that the locking member can be moved to a preset position during installation. In this way, the locking member can be adsorbed at the preset position with the help of an external adsorption member, so that the locking member is unlocked, effectively solving the problem that the current invisible fastener is inaccurately positioned after being installed on the mounting plate, which affects the removal of the invisible fastener, facilitating the installation and removal of the fastener and making it easier for users to use.

[0035] See also Figures 1 to 5 The present invention provides a tightening tool 200. This tightening tool 200 is used to install a mounting fastener 100 into a fixture plate. This allows the locking member 112 of the mounting fastener 100 to be positioned in a predetermined position after the mounting fastener 100 is installed into the furniture plate, making it easier for an outsider to remove the mounting fastener 100 using a suction member. Of course, in other embodiments of the present invention, this tightening tool 200 can also be used to tighten and install other rotating parts.

[0036] Understandably, to ensure both the aesthetics and practicality of furniture, invisible fasteners are currently used to connect two mounting plates. These fasteners consist of a first portion, which is mounted in one mounting plate, and a second portion, which is mounted in the other. The first and second portions cooperate to connect the two mounting plates, and the fasteners can be concealed within the mounting plates. However, after installation, the position of these fasteners cannot be guaranteed, hindering their removal and making them inconvenient for users.

[0037] To this end, the present invention provides a new type of tightening tool 200, which indicates the installation position of the locking member 112 in the installation fastener 100 during the process of installing the installation fastener 100 to the furniture panel, so that the locking member 112 can be in a preset position, facilitating the disassembly of the locking member 112.

[0038] See also Figures 6 to 8 In order to facilitate the description of the tightening tool 200 , the structure of the installation fastener 100 is briefly described first, so as to explain how the tightening tool 200 realizes the installation of the installation fastener 100 .

[0039] In one embodiment, a mounting fastener 100 is used to connect a first plate and a second plate 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 plate. The 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 and a locking groove 1112 disposed in the radial direction. The locking groove 1112 is connected to the mating hole 1111. The locking member 112 is disposed in the locking groove 1112 and can move radially along the locking groove 1112. The mounting rod 120 includes one end of the second mounting rod 120 disposed in the second plate, and the other end of the mounting rod 120 can extend into the mating hole 1111 and be locked by the locking member 112. When the locking member 112 moves away from the mounting rod 120 in the radial direction, the mounting rod 120 can move out of the mating hole 1111.

[0040] The mounting fastener 100 can achieve a spliced connection between furniture panels. This description will be made using the example of a furniture panel comprising a first panel and a second panel. A portion of the mounting fastener 100 is disposed at the end of the first panel, while the other end of the mounting fastener 100 is disposed at the end of the second panel. By coupling the portion of the mounting fastener 100 on the first panel with the portion of the mounting fastener 100 on the second panel, a spliced connection between the first panel and the second panel can be achieved. Furthermore, through the coupling of the mounting assembly 210, 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 aesthetics of the connected furniture panels.

[0041] Mounting assembly 210 includes a connecting assembly 110 and a mounting rod 120. The end of the first plate has a connecting hole, into which connecting assembly 110 is screwed. The end of the second plate also has an inner hole, into which one end of mounting rod 120 is fixedly mounted. When the first and second plates are spliced together, the other end of mounting rod 120 can extend into connecting assembly 110. Connecting assembly 110 locks mounting rod 120, restricting its axial movement. To disassemble the first and second mounting plates, unlock connecting assembly 110, allowing mounting rod 120 to be removed.

[0042] Connecting assembly 110 includes a mounting sleeve 111 and a locking member 112. Mounting sleeve 111 has a mating hole 1111 extending axially therethrough, enabling installation of mounting rod 120. Mounting sleeve 111 also has a locking slot 1112 extending radially therethrough, communicating with mating hole 1111. Locking member 112 can be mounted in slot 1112. Locking member 112 can move radially within slot 1112 to lock or unlock mounting rod 120.

[0043] Locking member 112 has a locked position and an unlocked position. Locking member 112 can move between the locked and unlocked positions when it moves radially within locking slot 1112. When in the locked position, locking member 112 can abut against mounting rod 120 in mating hole 1111, restricting axial movement of mounting rod 120. When in the unlocked position, locking member 112 disengages from mounting rod 120, allowing mounting rod 120 to move axially out of mating hole 1111.

[0044] Furthermore, the locking member 112 is normally in the locked position. During installation of the mounting rod 120 into the mating hole 1111, the mounting rod 120 can lift the locking member 112, causing the locking member 112 to move from the locked position to the unlocked position. Once the mounting rod 120 is fully seated in the mating hole 1111, the locking member 112 moves downward and resets, moving from the unlocked position to the locked position. At this point, the locking member 112 locks the mounting rod 120, completing the connection between the first and second panels.

[0045] When the first plate and the second plate need to be disassembled, the locking member 112 is controlled to move upward so that the locking member 112 is disengaged 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 matching hole 1111. It can be understood that the upward movement of the locking member 112 when unlocked can be controlled by an adsorption member. The adsorption member can adsorb the locking member 112 so that the locking member 112 moves 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 can also be other components that can achieve adsorption or a structure that controls the upward movement of the locking member 112.

[0046] The installation fastener 100 of the above embodiment realizes the locking and unlocking of the installation rod 120 through the radial movement of the locking member 112, thereby realizing the installation and disassembly of the first plate and the second plate. It can effectively solve the problems of complex structure and inconvenient disassembly when the current invisible fasteners are used to connect the installation plates, facilitate the rapid assembly and disassembly of the first plate and the second plate, and is easy for users to use.

[0047] See also Figures 6 to 8 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. 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 matching hole 1111.

[0048] Locking block 1121 is the main structure that locks and unlocks locking member 112. Locking block 1121 is installed in locking groove 1112 and can move radially along locking groove 1112. Resetting member 1122 has an elastic force that connects locking block 1121 to mounting sleeve 111. After locking block 1121 is installed in locking groove 1112, the elastic force generated by reset member 1122 can make locking member 112 and mounting sleeve 111 fit together, ensuring that locking block 1121 is in the locked position.

[0049] 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, thereby facilitating the installation of the mounting rod 120. After the mounting rod 120 moves to the specified 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. The elastic force of the reset member 1122 can then drive the locking block 1121 to reset, causing the locking block 1121 to move from the unlocked position to the locked position. The elastic force of the reset member 1122 cooperates with the locking block 1121 to lock the mounting rod 120.

[0050] When unlocking, the suction force exerted by the suction member on locking block 1121 is greater than the elastic force exerted by reset member 1122. At this point, the suction member is able to overcome the elastic force of reset member 1122 and drive locking block 1121 upward to the unlocked position. At this point, locking block 1121 is disengaged from mounting rod 120, allowing mounting rod 120 to move out of mating hole 1111, completing the disassembly of the first and second panels. After disassembly is complete, locking block 1121 is removed, and no longer subjected to the suction force. The elastic force of reset member 1122 resets locking block 1121 to its locked position.

[0051] In one embodiment, the reset member 1122 includes an elastic ring. That is, the locking block 1121 switches between the locked position and the unlocked position by cooperating with the elastic ring. Specifically, after the locking block 1121 is set in the locking groove 1112, the elastic ring is simultaneously sleeved on the outside of the mounting sleeve 111 and the locking block 1121, and the position of the locking block 1121 is restricted by the elastic ring, so that the locking block 1121 is in the locked position. In addition, when the external force applied to the locking block 1121 exceeds the elastic force of the elastic ring, the locking block 1121 moves away from the mating hole 1111, and the mounting rod 120 can be installed in the mating hole 1111 or removed from the mating hole 1111. When the locking block 1121 is not subjected to external force or the external force applied is less than the elastic force of the elastic ring, the elastic ring can drive the locking block 1121 to move to the locked position. Optionally, the elastic ring is made of a rubber ring or other material with elastic force.

[0052] See also Figures 6 to 8 In one embodiment, the outer circumference of the locking block 1121 has a first limiting groove 11211, and the outer circumference of the mounting sleeve 111 has a second limiting groove 1113 that communicates 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 limit the position of the elastic ring, preventing it from sliding out, so that the elastic ring is fixed in the position of the locking block 1121, ensuring that the elastic ring can accurately drive the locking block 1121 to return to its original position.

[0053] See also Figures 6 to 8 In one embodiment, the mounting sleeve 111 includes a first mounting segment 1114 and a second mounting segment 1115, the outer diameter of the first mounting segment 1114 is larger than the outer diameter of the second mounting segment 1115, the first mounting segment 1114 has the locking groove 1112, and there is a preset distance between the edge of the locking groove 1112 and the end of the first mounting segment 1114, which is used to limit the axial position of the locking member 112.

[0054] In one embodiment, the mounting fastener 100 further includes a mounting sleeve 130. The outer surface of the mounting sleeve 130 at least partially has external threads for installation in the connection hole of the first plate. The mounting sleeve 111 is interference fit within the mounting sleeve 130. The mounting sleeve 130 defines a first through hole 131 and a second through hole 132. The first through hole 131 communicates with the second through hole 132 and extends through the mounting sleeve 130. The inner diameter of the second through hole 132 is smaller than that of the first through hole 131. The first through hole 131 is used to mount the first mounting segment 1114, and the second through hole 132 is used to mount the second mounting segment 1115. The end of the second through hole 132 communicates with a tightening groove 133, which is configured to engage with the tightening segment 2115 of the tightening tool 200.

[0055] The installation sleeve 130 can play a protective role, in which the connecting component 110 is installed. The connecting component 110 is installed in the first plate through the installation sleeve 130. Specifically, the installation sleeve 111 is installed in the installation sleeve 130 with an interference fit, so that the installation sleeve 111 and the installation sleeve 130 form an integral structure, ensuring that the installation sleeve 111 will not rotate relative to the installation sleeve 130. In this way, when the installation sleeve 130 is installed on the first plate, the installation sleeve 111 is installed in the installation sleeve 130, and one end of the installation sleeve 130 is placed in the connecting hole. The installation sleeve 130 is rotated, and the installation sleeve 130 can drive the installation sleeve 111 therein to rotate synchronously, so that the installation sleeve 111 is installed in the first plate. It can be understood that the installation sleeve 130 is installed in the connecting hole of the first plate by self-tapping.

[0056] Optionally, the installation of the mounting sleeve 130 and the mounting sleeve 111 can be installed by knocking to ensure that the mounting sleeve 111 can be accurately installed in the mounting sleeve 130. Optionally, the mounting sleeve 130 can be installed in the first plate by electric means or manually.

[0057] The interior of the mounting sleeve 130 defines a first through-hole 131 and a second through-hole 132. The first through-hole 131 and the second through-hole 132 are connected to each other and extend axially through the entire mounting sleeve 130. The outer diameter of the first through-hole 131 is larger than that of the second through-hole 132. The first mounting segment 1114 can be mounted in the first through-hole 131, and the second mounting segment 1115 can be mounted in the second through-hole 132. The second through-hole 132 and the second mounting segment 1115 cooperate to secure the mounting sleeve 111.

[0058] See also Figures 6 to 8 、 Figure 1In one embodiment, the end of the second mounting section 1115 away from the first mounting section 1114 has a mating portion 11151, and the extension line of the mating portion 11151 is located in the locking groove 1112, and the mating portion 11151 is used to cooperate with the positioning portion 22111 of the tightening tool 200.

[0059] The mating portion 11151 is used to achieve the positioning of the locking member 112, so that the locking member 112 is in a preset position after installation, which facilitates the removal of the locking member 112 through the adsorption member. The preset position here is the position directly above the first plate. After the installation sleeve 130 drives the installation sleeve 111 and the locking member 112 to be screwed into the first plate, the locking member 112 is inside the first plate. When the locking member 112 is in the preset position, the adsorption member is moved in directly above the first plate, and the adsorption member can control the locking member 112 to unlock. If the locking member 112 deviates from the preset position, after the adsorption member is moved into the preset position, the adsorption force generated by the adsorption member on the locking member 112 is less than the elastic force generated by the reset member 1122, and the locking member 112 cannot be unlocked.

[0060] Therefore, when installing sleeve 130 into the first plate, it is necessary to ensure that locking member 112 is in the preset position. It will be appreciated that the number of rotations required for installing sleeve 130 into the first plate corresponds to the distance it moves. Therefore, when installing sleeve 130 is placed at the end of the connection hole in the first plate, with locking member 112 facing a certain direction, rotating sleeve 130 until fully installed into the first plate ensures that locking member 112 is in the preset position, facilitating installation and removal of mounting rod 120.

[0061] It's worth noting that the preset position isn't limited to the top of the first plate; it can also be a position where other adsorbents can unlock the locking member 112. Assuming that installation can be completed after nine rotations of the installation sleeve 130, when the installation sleeve 130 is placed at the end of the connection hole of the first plate, with the locking member 112 facing the preset position, after nine rotations, the locking member 112 is in the preset position. Of course, in other embodiments of the present invention, the installation sleeve 130 can also be rotated a different number of times to achieve installation.

[0062] After the locking member 112 is installed in the mounting sleeve 130 and the mounting sleeve 130 is installed on the first plate, it is difficult for the user to know the installation position of the locking member 112, and therefore it is impossible to determine whether the locking member 112 has reached the preset position. To this end, the mounting fastener 100 of the present invention is provided with a mating portion 11151 at the end of the second mounting section 1115 of the mounting sleeve 111. After the mating portion 11151 is connected to the positioning portion 22111 of the tightening tool 200, the user can know the installation position of the locking member 112 through the positioning portion 22111 of the tightening tool 200, so that the locking member 112 is in the preset position after installation, facilitating the removal of the mounting fastener 100.

[0063] Optionally, the central axis of the mating portion 11151 coincides with the central axis of the locking groove 1112. In this way, the mating portion 11151 can indicate the installation position of the locking member 112 by mating with the tightening tool 200. Of course, in other embodiments of the present invention, the central axis of the mating portion 11151 can also be located in the locking groove 1112. In this way, the mating portion 11151 can also indicate the installation position of the locking member 112 by mating with the tightening tool 200. Optionally, the mating portion 11151 is a mating groove that extends axially to the end of the second mounting section 1115. Of course, in other embodiments of the present invention, the mating portion 11151 can also be other structures that can cooperate with the positioning portion 22111 for positioning.

[0064] See also Figures 6 to 8 In one embodiment, the mounting rod 120 includes a limiting section 121, a connecting section 122 and a fixing section 1213 connected in sequence. The fixing section 1213 is used to be installed in the second plate. After the limiting section 121 extends into the matching hole 1111, the limiting section 121 can cooperate with the locking member 112 to limit the axial movement of the mounting rod 120.

[0065] Mounting rod 120 is a stepped rod. One end of connecting section 122 is connected to fixing section 1213, and the other end of connecting section 122 is connected to limiting section 121. Fixing section 1213 is fixedly mounted within the inner hole of the second plate, while limiting section 121 and connecting section 122 extend beyond the second plate. When the second plate is connected to the first plate, limiting section 121 gradually extends along mating hole 1111 into mounting sleeve 111 in the first plate. The limiting section 121 engages with locking member 112 to lock mounting rod 120, thereby achieving the connection between the first and second plates.

[0066] When the first plate and the second plate are disassembled, the adsorption member adsorbs the locking member 112 on the first plate, so that the locking member 112 moves to the unlocking position, and the limiting section 121 can be moved out of the locking member 112, and then the installation sleeve 111 is moved out, thereby realizing the disassembly of the first plate and the second plate.

[0067] Optionally, the limiting section 121, the connecting section 122, and the fixing section 1213 are integrally formed. Optionally, the fixing section 1213 has external threads, and the inner hole of the second plate has internal threads, and the internal and external threads cooperate to achieve a fixed connection between the fixing section 1213 and the second plate. Of course, in other embodiments of the present invention, the fixing section 1213 and the second plate may also be connected in other ways, as long as the connection is reliable.

[0068] In one embodiment, the limiting section 121 has a recessed portion 1211, which is used to mount the locking block 1121. The inner wall of the recessed portion 1211 can abut against the locking block 1121. The recessed portion 1211 is recessed in the surface of the limiting section 121. After the locking block 1121 is engaged with the mounting rod 120, the locking block 1121 is located in the recessed portion 1211. The inner wall of the recessed portion 1211 can abut against the end of the locking block 1121. The inner wall of the recessed portion 1211 limits the axial movement of the locking block 1121. At the same time, the locking block 1121 can also limit the axial movement of the mounting rod 120, thereby locking the mounting rod 120.

[0069] In one embodiment, the end of the limiting section 121 is a pointed end 1212 , which can reduce the installation resistance of the mounting rod 120 and facilitate the installation of the mounting rod 120 into the matching hole 1111 .

[0070] In one embodiment, the locking member 112 is made of a magnetic material, while the mounting sleeve 130, the mounting sleeve 111, the reset member 1122, and the mounting rod 120 are made of a non-magnetic material. This allows the attracting member to attract only the locking member 112, allowing the locking member 112 to move from the locked position to the unlocked position without causing other components to move, thus ensuring reliable unlocking of the locking member 112.

[0071] See also Figures 6 to 8 When the above-mentioned mounting fastener 100 is in use, the locking block 1121 is installed in the locking groove 1112 of the mounting sleeve 111, and the locking block 1121 and the mounting sleeve 111 are connected by the reset member 1122, so that the locking block 1121 is in the locked position. Subsequently, the mounting sleeve 111 is installed in the mounting sleeve 130, and the two are ensured to be reliably connected. One end of the mounting sleeve 130 is placed in the connection hole of the first plate by a tightening tool 200 or other tool, and the locking member 112 is directed toward the preset position by the cooperation of the fitting portion 11151 and the positioning portion 22111. The mounting sleeve 130 is rotated by means of the tightening tool 200 or other means, so that the mounting sleeve 130 is screwed into the first plate and the locking block 1121 is directed toward the preset position.

[0072] The mounting rod 120 is installed into the second plate through the fixing section 1213. When connecting the first plate and the second plate, the limiting section 121 of the mounting rod 120 is installed in the matching hole 1111 and moves along the matching hole 1111. When the limiting section 121 of the mounting rod 120 contacts the locking block 1121, the limiting section 121 can lift the locking block 1121, allowing the locking block 1121 to overcome the elastic force of the return member 1122 and move from the locked position to the unlocked position. The limiting section 121 continues to move along the matching hole 1111. When the limiting section 121 does not apply a 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, and the locking block 1121 can be clamped in the recessed portion 1211. The axial movement of the mounting rod 120 is limited by the cooperation between the locking block 1121 and the recessed portion 1211, thereby achieving the locking of the mounting rod 120 and further achieving the connection between the first plate and the second plate.

[0073] When the first and second plates need to be disassembled, an adsorption member, such as a magnet, is moved to a preset position on the first plate, and the adsorption member adsorbs the locking block 1121. At this point, the adsorption force exerted by the adsorption member on the locking block 1121 is greater than the elastic force exerted by the reset member 1122 on the locking block 1121. Under the action of the adsorption force, the locking block 1121 moves from the locked position to the unlocked position. At this point, the second plate is dragged outward, and the second plate can drive the mounting rod 120 out of the mating hole 1111, thereby achieving the disassembly of the first and second plates. After the adsorption member is removed, the elastic force of the reset member 1122 can drive the locking block 1121 from the unlocked position to the locked position.

[0074] To ensure that the locking member 112 in the mounting fastener 100 can be installed in the preset position, the present invention adds a tightening tool 200. The tightening tool 200 locates the installation position of the locking member 112, so that the locking member 112 can be in the preset position after installation, making it convenient for the user to remove it. The specific structure of the tightening tool 200 is described in detail below.

[0075] See also Figures 1 to 5 In one embodiment, a tightening tool 200 is used to install a mounting fastener 100 into a furniture panel through an installation sleeve 130. The tightening tool 200 includes an installation assembly 210 and a positioning assembly 220. One end of the installation assembly 210 contacts the installation sleeve 111 in the installation sleeve 130, and the other end is connected to an operating tool. One end of the positioning assembly 220 is retractably mounted within the installation assembly 210, while the other end of the positioning assembly 220 is capable of extending into the mounting fastener 100. The positioning assembly 220 can indicate the installation position of the locking member 112 in the mounting fastener 100.

[0076] The tightening tool 200 is capable of installing the mounting sleeve 111 of the connecting assembly 110 of the fastener 100 into the first panel of the furniture board through the mounting sleeve 130. Specifically, after the mounting sleeve 111 is installed in the mounting sleeve 130, the positioning assembly 220 of the tightening tool 200 is connected to the end of the mounting sleeve 111. Then, the tightening tool 200 is used to place one end of the mounting sleeve 130 into the connection hole of the first panel. After the operating tool is installed in the mounting assembly 210, the operating tool is controlled to rotate, thereby driving the tightening tool 200 to rotate. As the tightening tool 200 rotates, the tightening tool 200 can control the mounting sleeve 130 to be screwed into the first panel. Because the tightening tool 200 is connected to the mounting sleeve 111, it can locate the installation position of the locking member 112. After the mounting sleeve 111 is installed in the first panel, the tightening tool 200 can indicate the installation position of the locking member 112, facilitating the installation of the locking member 112 to the preset position and facilitating the removal of the fastener 100.

[0077] Specifically, the tightening tool 200 includes a mounting assembly 210 and a positioning assembly 220. The mounting assembly 210 serves as the mounting body 211 of the tightening tool 200, supporting the various components of the tightening tool 200. One end of the mounting assembly 210 is retractably mounted to the positioning assembly 220, while the other end of the mounting assembly 210 can be mounted with an operating tool. The end of the positioning assembly 220, distal from the mounting assembly 210, can be mounted in the mounting sleeve 111 of the mounting fastener 100, indicating the installation position of the locking member 112 through the positioning assembly 220.

[0078] When installing the mounting fastener 100 to the first plate, first mate one end of the mounting sleeve 111 with the end of the positioning assembly 220. Then, tightening tool 200 installs the mounting sleeve 111 to one end of the first plate and adjusts the installation angle of the mounting sleeve 111. Then, tightening tool 200 rotates and drives the mounting sleeve 130 to rotate and install it in the first plate. At this point, the orientation indicated by the positioning assembly 220 is the preset position of the locking member 112. When removing the mounting fastener 100, the suction member is moved to the preset position, which unlocks the locking member 112, thereby unlocking the mounting sleeve 111 and the mounting rod 120, thereby achieving the removal of the first and second plates.

[0079] The tightening tool 200 in the above embodiment can ensure the effective installation of the locking member 112, so that the locking member 112 can be in a preset position, facilitating the removal of the installation fastener 100. Specifically, when the operating tool rotates, the installation assembly 210 can be used to drive the installation cover 130 and the installation fastener 100 therein to rotate, so that the installation cover 130 and the installation space therein can be screwed into the furniture plate. The positioning assembly 220 is used to know the installation position of the locking member in the installation fastener 100, so that the locking member can be moved to the preset position during installation. In this way, the locking member can be adsorbed at the preset position with the help of an external adsorption member, so that the locking member is unlocked. This effectively solves the problem of the current invisible fastener being inaccurately positioned after being installed on the installation plate, which affects the removal of the invisible fastener, facilitates the installation and removal of the installation fastener 100, and is convenient for users to use.

[0080] See also Figures 1 to 5 In one embodiment, the mounting assembly 210 includes a mounting body 211 and a connecting rod 212, the mounting body 211 having a first end and a second end arranged opposite to each other in the axial direction, the first end having a mounting hole 2111 extending in the axial direction, the mounting hole 2111 being used for telescopically mounting the positioning assembly 220, the second end being a connecting rod 212 extending in the axial direction, the connecting rod 212 being used to connect the operating tool.

[0081] The mounting body 211 is the main structure of the mounting assembly 210, supporting the various components of the tightening tool 200. Axially, the mounting body 211 has a first end and a second end that are positioned opposite each other. The first end of the mounting body 211 has a mounting hole 2111, and the second end of the mounting body 211 is used to securely mount a connecting rod 212. The other end of the connecting rod 212 can be used to mount an operating tool.

[0082] The positioning assembly 220 is retractably mounted in the mounting hole 2111, allowing the positioning assembly 220 to abut against the mounting sleeve 111, thereby allowing the end of the mounting sleeve 130 to abut against the second end of the mounting body 211. This facilitates the mounting body 211 to rotate the mounting sleeve 130, thereby screwing the mounting sleeve 130 into the first plate. Optionally, the operating tool is a wrench or electric drill. Optionally, the mounting body 211 and the connecting rod 212 are integrally formed, which enhances the structural strength of the mounting assembly 210 and ensures its performance.

[0083] See also Figures 1 to 5In one embodiment, the mounting body 211 further includes a hollow tightening section 2115 disposed at a first end of the mounting body 211 and engaging with the tightening slot 133 of the mounting sleeve 130. The tightening section 2115 drives the mounting sleeve 130 into the furniture panel via the inner wall of the tightening slot 133. The engagement of the tightening section 2115 with the tightening slot 133 allows the mounting sleeve 130 to be screwed into the first panel, facilitating a seamless connection between the first and second panels.

[0084] It is understood that the connection between the positioning assembly 220 and the installation sleeve 111 is primarily to position the locking member 112 so that the locking member 112 can be installed in a predetermined position. After the positioning assembly 220 positions the locking member 112, when the tightening tool 200 needs to screw the installation sleeve 130, the installation sleeve 111, and the locking member 112 therein into the first plate, the cooperation between the installation body 211 and the installation sleeve 130 is achieved, thereby preventing the positioning assembly 220 and the installation sleeve 111 from being subjected to force, thereby preventing damage to the positioning assembly 220 and allowing the installation sleeve 130 to move into position.

[0085] A tightening section 2115 is provided at the first end of the mounting body 211. Tightening section 2115 protrudes from the cross-section of the first end of the mounting body 211. Tightening section 2115 is hollow and communicates with the mounting hole 2111, allowing positioning assembly 220 to pass through. After positioning assembly 220 is positioned and connected to mounting sleeve 111, tightening section 2115 is partially located within mounting sleeve 130 and engages with tightening groove 133 of mounting sleeve 130. The outer wall of tightening section 2115 is able to abut against the inner wall of tightening groove 133.

[0086] When screwing in, the installation body 211 is pushed toward the installation sleeve 130. The installation body 211 compresses the positioning assembly 220, so that the tightening section 2115 is completely located in the tightening groove 133, and the end of the installation sleeve 130 is able to abut the first end of the installation body 211. When the operating tool drives the installation body 211 to rotate via the connecting rod 212, the installation body 211 can drive the tightening section 2115 to rotate. The rotation of the tightening section 2115 can also drive the tightening groove 133 to rotate. The rotation of the tightening groove 133 drives the installation sleeve 130 to rotate, allowing the installation sleeve 130 to be screwed into the first plate.

[0087] Optionally, the inner wall of the tightening groove 133 is polygonal, and accordingly, the outer wall of the tightening section 2115 is also polygonal. The tightening section 2115 cooperates with the tightening groove 133 to drive the installation sleeve 130 to rotate. For example, the tightening section 2115 is an outer hexagon, and the tightening groove 133 is an inner hexagon. Of course, in other embodiments of the present invention, a recessed area can be provided in the tightening groove 133 to cooperate with the protrusion of the tightening section 2115.

[0088] See also Figures 1 to 5 In one embodiment, the positioning assembly 220 includes a telescopic component 221 and an indicating component 222. The telescopic component 221 can be telescopically arranged in the mounting hole 2111, and the indicating component 222 can be rotatably mounted on the mounting body 211 and connected to the telescopic component 221. The indicating component 222 can be telescopic and rotated with the telescopic component 221.

[0089] One end of the telescopic member 221 is retractably disposed within the mounting hole 2111 of the mounting body 211. The other end of the telescopic member 221 is free and detachably connectable to the mounting sleeve 111, thereby indicating the position of the locking member 112. Furthermore, when the telescopic member 221 is retracted, it securely connects the tightening groove 133 of the mounting sleeve 130 with the tightening section 2115, facilitating the tightening tool 200 to screw the mounting sleeve 130 into the first plate.

[0090] The indicator component 222 is connected to the telescopic component 221. Rotation of the telescopic component 221 drives the indicator component 222 to rotate. Furthermore, when the operating tool rotates the mounting body 211 via the connecting rod 212, the mounting body 211 drives the positioning assembly 220 and the indicator component 222 to rotate simultaneously. The indicator component 222 is positioned outside the mounting body 211, allowing the user to determine the orientation of the locking member 112 by observing the orientation of the indicator component 222. When the mounting sleeve 130 is screwed onto the first plate, the orientation of the indicator component 222 indicates the installed position of the locking member 112, ensuring that the locking member 112 is in the desired position.

[0091] See also Figures 1 to 5 In one embodiment, the surface of the mounting body 211 has a avoidance groove 2112, which extends along the circumferential direction and the axial direction of the mounting body 211 and is connected to the mounting hole 2111. The indicating component 222 passes through the avoidance groove 2112 to connect to the telescopic component 221.

[0092] The avoidance groove 2112 serves as a relief mechanism. It is located on the outer circumference of the mounting body 211 and radially connects to the mounting hole 2111. The avoidance groove 2112 has a predetermined length in the axial direction and a predetermined width in the circumferential direction. The indicator component 222 can pass through the avoidance groove 2112 and be mounted on the telescopic component 221 in the mounting space. Furthermore, the indicator component 222 can move axially and / or circumferentially within the avoidance groove 2112.

[0093] When the indicator member 222 moves in the circumferential direction, it can adjust the angle of the tightening section 2115 in the installation body 211 so that the tightening section 2115 can mate with the tightening groove 133 of the installation sleeve 130. It is understood that after the telescopic member 221 is connected to the end of the installation sleeve 111, there will be a phase difference between the tightening section 2115 and the tightening groove 133. At this time, the installation body 211 rotates relative to the telescopic member 221 to adjust the angle of the tightening section 2115 so that the tightening section 2115 can be installed in the tightening groove 133, thereby facilitating the installation body 211 to drive the installation sleeve 130 to be screwed into the first plate.

[0094] When the indicator component 222 moves in the axial direction, the end of the telescopic component 221 is connected to the end of the mounting sleeve 111, and the tightening section 2115 is partially installed in the tightening groove 133. At this time, the mounting body 211 is pushed toward the mounting sleeve 130, and the mounting body 211 can move relative to the indicator component 222, causing the telescopic component 221 to retract into the mounting hole 2111, thereby allowing the tightening section 2115 to fully enter the tightening groove 133 and causing the end of the mounting sleeve 130 to abut against the first end of the mounting body 211. In this way, when the mounting body 211 rotates, the mounting body 211 can drive the mounting sleeve 130 to be screwed into the first plate through the cooperation between the tightening section 2115 and the tightening groove 133.

[0095] In one embodiment, the central angle of the relief groove 2112 ranges from 60° to 180°. This ensures that the tightening section 2115 precisely mates with the tightening groove 133, facilitating screwing the installation sleeve 130. Optionally, the central angle of the relief groove 2112 ranges from 120°.

[0096] See also Figures 1 to 5 In one embodiment, the telescopic component 221 includes a positioning rod 2211 and an elastic member 2212. The elastic member 2212 is arranged in the mounting hole 2111. The positioning rod 2211 is installed in the mounting hole 2111 and abuts against the elastic member 2212. The positioning rod 2211 can compress the elastic member 2212 or the elastic force of the elastic member 2212 can reset the positioning rod 2211.

[0097] Positioning rod 2211 is a cylindrical rod, and elastic member 2212 provides elastic force for the telescopic movement of telescopic member 221. Elastic member 2212 is installed in mounting hole 2111, with one end of elastic member 2212 abutting the inner wall of mounting hole 2111. After positioning rod 2211 is installed in mounting hole 2111, the end of positioning rod 2211 can abut against the other end of elastic member 2212. The end of positioning rod 2211 extending beyond mounting body 211 can connect to the end of mounting sleeve 111.

[0098] After the positioning rod 2211 is connected to the installation sleeve 111, it pushes the installation body 211 toward the installation sleeve 130. When the pushing force on the positioning rod 2211 is greater than the elastic force of the elastic member 2212, the positioning rod 2211 compresses the elastic member 2212, allowing the installation body 211 to move toward the installation sleeve 130. When the installation body 211 is released, the positioning rod 2211 is no longer subject to external force. At this time, the elastic force of the elastic member 2212 can push the installation body 211 or the positioning rod 2211 to return to its original position.

[0099] Optionally, the elastic member 2212 is a spring. Of course, in other embodiments of the present invention, the elastic member 2212 can also be other components with elastic force.

[0100] See also Figures 1 to 5 In one embodiment, the indicating component 222 includes a fixing member 2221, the positioning rod 2211 has a fixing hole 22112 along the radial direction, the fixing member 2221 passes through the avoidance groove 2112 and is installed in the fixing hole 22112 of the positioning rod 2211, and the fixing member 2221 can move with the positioning rod 2211 in the avoidance groove 2112.

[0101] The fixing member 2221 is the indicator element of the indicator component 222. The fixing member 2221 can pass through the avoidance groove 2112 and be installed in the fixing hole 22112 of the positioning rod 2211. The positioning rod 2211 can drive the fixing member 2221 to move and rotate synchronously. At the same time, the fixing member 2221 can also contact the inner wall of the avoidance groove 2112, limiting the rotation and movement of the positioning rod 2211.

[0102] The fixing member 2221 is positioned outside the mounting body 211, and its position is collinear with the position of the locking member 112. After the positioning rod 2211 is connected to the mounting sleeve 111, the fixing member 2221 can indicate the position of the locking member 112. When the mounting body 211 rotates the positioning rod 2211, the positioning rod 2211 drives the fixing member 2221 to rotate synchronously, allowing the fixing member 2221 to accurately indicate the position of the locking member 112. Alternatively, the fixing member 2221 can be a bolt, pin, or the like.

[0103] See also Figures 1 to 5 In one embodiment, one end of the positioning rod 2211 has a positioning portion 22111, and the positioning portion 22111 is connected to the matching portion 11151 in the mounting fastener 100. The positioning portion 22111 and the mounting hole 2111 are arranged along the same axial direction to indicate the installation position of the locking member 112.

[0104] The positioning portion 22111 is used to indicate the installation position of the locking member 112. After the positioning rod 2211 is connected to the installation sleeve 111, the positioning portion 22111 is engaged with the mating portion 11151. Since the central axis of the mating portion 11151 is located within the locking member 112, the positioning portion 22111 can indicate the installation position of the locking member 112. Furthermore, since the positioning portion 22111 and the fixing member 2221 are arranged colinearly, the positioning portion 22111 and the mating portion 11151 engage to indicate the position of the locking member 112 through the fixing member 2221, allowing the locking member 112 to be installed in the preset position.

[0105] Optionally, the positioning portion 22111 is a protrusion extending in the radial direction, and correspondingly, the matching portion 11151 is a groove. Of course, in other embodiments of the present invention, the positioning portion 22111 and the matching portion 11151 can also be other structures capable of positioning.

[0106] See also Figures 1 to 5 In one embodiment, the indicating component 222 also includes a sliding sleeve 2222, which can be slidably mounted on the outer side of the mounting body 211, and the sliding sleeve 2222 has a through hole set therethrough, and the fixing member 2221 can be installed in the fixing hole 22112 of the positioning rod 2211 by passing through the through hole and the avoidance groove 2112.

[0107] Sliding sleeve 2222 is mounted on the outside of mounting body 211 and can slide along mounting body 211. Mounting body 211 has a through hole, through which fixing member 2221 passes and through retaining groove 2112 to be installed in fixing hole 22112 of positioning rod 2211. Sliding sleeve 2222 provides a shielding function, preventing debris from entering the sliding groove, ensuring the performance of tightening tool 200, while also preventing accidental contact and ensuring safety.

[0108] See also Figures 1 to 5 In one embodiment, the mounting assembly 210 further includes a mounting boss 2113, which is disposed at the first end of the mounting body 211 and located between the mounting body 211 and the tightening section 2115. The outer diameter of the mounting boss 2113 is smaller than the outer diameter of the mounting body 211 and larger than the outer diameter of the tightening section 2115. The mounting boss 2113 is used to screw the mounting sleeve 130 into the interior of the furniture panel.

[0109] As is understood, the sheet material typically has a rim to ensure both the aesthetics and practicality of the sheet material. The rim has a certain thickness. The mounting boss 2113 enables the mounting sleeve 130 to be screwed into the first sheet material and is located on the inner side of the rim.

[0110] Specifically, the mounting boss 2113 is disposed between the mounting body 211 and the tightening section 2115. The outer diameter of the mounting boss 2113 is larger than the outer diameter of the tightening section 2115, but smaller than the outer diameter of the mounting body 211. When the positioning rod 2211 is connected to the mating portion 11151 of the mounting sleeve 111 via the positioning portion 22111, the mounting body 211 is pushed, allowing the tightening section 2115 to be installed into the tightening groove 133. At this point, the end of the mounting sleeve 130 can abut against the mounting boss 2113.

[0111] When tightening tool 200 screws mounting sleeve 130 into the first sheet, mounting boss 2113 also enters the first sheet and forms the corresponding edge. This ensures that mounting sleeve 130 is fully inserted into the first sheet, preventing a gap from forming at the junction between the first and second sheets. Optionally, mounting boss 2113 has the same thickness as the edge.

[0112] In one embodiment, the mounting body 211 is cylindrical. Optionally, the mounting body 211 is tapered at the end where the mounting body 211 is connected to the connecting rod 212. This can reduce the weight of the mounting body 211 while ensuring a reliable connection.

[0113] In one embodiment, the mounting body 211 further comprises a limiting step 2114 disposed on the outer periphery of the mounting body 211. The limiting step 2114 can limit the displacement of the sliding sleeve 2222, preventing the sliding sleeve 2222 from overtravel. Optionally, the outer diameter of the limiting step 2114 is the same as the outer diameter of the sliding sleeve 2222.

[0114] See also Figures 1 to 5 When the tightening tool 200 of the present invention is used, the mounting sleeve 111 and the locking member 112 are installed in the mounting sleeve 130 to form an integral structure. Subsequently, the mounting sleeve 111 is connected to the end of the tightening tool 200. Specifically, the angle of the mounting sleeve 130 is adjusted so that the positioning rod 2211 is connected to the matching portion 11151 in the mounting sleeve 111 through the positioning portion 22111. Subsequently, the mounting body 211 is rotated left and right so that the mounting body 211 is rotated relative to the fixing member 2221 through the avoidance groove 2112, and the angle of the tightening section 2115 on the mounting body 211 is adjusted so that the tightening section 2115 can be installed in the tightening groove 133 of the mounting sleeve 130.

[0115] Then, one end of the mounting sleeve 130 is placed in the first plate, and the mounting body 211 is pushed toward the mounting sleeve 130, so that the tightening section 2115 is completely inserted into the tightening groove 133, ensuring that the mounting sleeve 130 is attached to the mounting boss 2113 at the first end of the mounting body 211. The operating tool is controlled to operate. When the operating tool is rotated, it can drive the mounting body 211 to rotate via the connecting rod 212. The mounting body 211 drives the mounting sleeve 130 to rotate through the tightening section 2115 and the tightening groove 133, so that the mounting sleeve 130 is screwed into the first plate.

[0116] After the installation sleeve 130 is installed on the first plate, the position indicated by the fixing member 2221 is achieved. During the actual installation process, the number of rotations of the installation sleeve 130 in the first plate is determined. Then, the installation sleeve 130 is placed at the end of the first plate in the manner indicated by the fixing member 2221. In this way, after the installation sleeve 130 is rotated the predetermined number of times, the locking member 112 will be exactly in the predetermined position.

[0117] Assuming that installation is completed after nine rotations of the installation sleeve 130, when the installation sleeve 130 is placed at the end of the connection hole of the first plate, the locking member 112 is oriented in the direction of the preset position. After the tightening tool 200 controls the installation sleeve 130 to rotate nine rotations, the locking member 112 is in the preset position. Of course, in other embodiments of the present invention, the installation sleeve 130 can also be rotated a different number of times to achieve installation.

[0118] After mounting rod 120 is mounted on mounting sleeve 111, locking member 112 is used to lock mounting rod 120, thereby connecting the first and second panels. To disassemble the first and second panels, the suction member is moved to a predetermined position. The suction member releases locking member 112 through suction, allowing mounting rod 120 to be removed from the first panel, thereby disassembling the first and second panels.

[0119] The tightening tool 200 of the present invention locates the position of the locking member 112 through the cooperation between the positioning portion 22111 and the matching portion 11151, and indicates the orientation of the locking member 112 through the fixing member 2221, and then screws the installation sleeve 130 into the first plate through the cooperation between the tightening section 2115 on the installation body 211 and the tightening groove 133. While ensuring the accurate installation of the installation sleeve 130, it can also effectively locate the position of the locking member 112, making it convenient for users to disassemble and install the fastener 100.

[0120] The technical features of the above-mentioned embodiments can be combined arbitrarily. In order to make the description concise, not all possible combinations of the technical features in the above-mentioned embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0121] The above-described embodiments merely illustrate several implementations of the present invention, and while their descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the patent. It should be noted that a person skilled in the art would be able to make numerous variations and improvements without departing from the spirit of the present invention, all of which fall within the scope of protection of the present invention. Therefore, the scope of protection of the patent for this invention shall be determined by the appended claims.
