Description

Technical Field

[0001] The present invention relates to the technical field of bolts, and in particular to an installation method for a bolt assembly and a bolt assembly that is not easily disassembled. Background Art

[0002] A bolt is a cylindrical threaded fastener that is used with a nut. It is a type of fastener composed of two parts: a head and a screw rod (a cylinder with external threads). It is used in cooperation with a nut or a threaded sleeve, and is usually used for fastening and connecting two parts. This connection form is called a bolt connection. Unscrewing the nut or the threaded sleeve from the bolt can also separate these two parts. Therefore, the bolt connection belongs to a detachable connection.

[0003] Bolt assemblies are widely used in various fields. Traditional bolts are generally exposed externally, which is convenient for technicians to disassemble or install them with tools. However, at the same time, there are also problems. Non-technicians can also disassemble the bolt assembly with tools. The disassembly of the bolt assembly has an impact on the quality of the product and may even cause safety accidents. In the current technology, there are also bolt assemblies that are not detachable. However, due to the exposure of the bolts, non-technicians can disassemble the bolt assembly in a violent manner, and technicians can only disassemble such bolts in a violent manner. The disassembly is rather troublesome. For some furniture or handicrafts, the exposure of the bolt assembly also affects the aesthetics.

[0004] Therefore, the present invention discloses an installation method for a bolt assembly and a bolt assembly that is not easily disassembled. Compared with the prior art, the bolt assembly in the present invention is hidden in the parts after installation, which is more aesthetically pleasing, and non-technicians are not easily able to disassemble it with traditional tools, and it has a high safety factor. Summary of the Invention

[0005] The purpose of the present invention is to overcome the deficiencies of the prior art, and provide an installation method for a bolt assembly and a bolt assembly that is not easily disassembled. Compared with the prior art, the bolt assembly in the present invention is hidden in the parts after installation, which is more aesthetically pleasing, and non-technicians are not easily able to disassemble it with traditional tools, and it has a high safety factor.

[0006] The present invention is achieved through the following technical solutions: An easily non-detachable bolt assembly, whose structure includes a first structural member provided with a threaded hole and a second structural member corresponding to the first structural member. The second structural member includes a metal member, a bolt portion, and a bearing. The bolt portion is arranged to be connected to the metal member at one end, and the bearing is arranged to be sleeved on the surface of the metal member. Among them, the metal member is a magnetic metal and is sleeved on the end far from the bolt portion.

[0007] For the bolt assembly in the present invention, the installation between parts is completed through the cooperation between the first structural member and the second structural member. Among them, when installation is required, a slot is opened in one part, the first structural member is installed and inlaid in the slot, a slot is also opened in the other part, and the metal part sleeved with a bearing is inlaid in the slot of the other part, so that the bolt part is exposed relative to the slot. The metal part is rotated, and the metal part drives the bolt part to rotate. During the rotation process, the bolt part rotates into the first structural member, thereby completing the connection between the first structural member and the second structural member. The bolt assembly in the present invention will not be exposed outside the parts after installation, thus achieving the effect of anti-disassembly.

[0008] Preferably, in order to facilitate the repair and replacement between the bolt part and the metal part, the bolt part and the metal part are detachably connected. Since the price of the bolt assembly of the invention is higher than that of the ordinary bolt assembly and the repair cost is relatively high, when the bolt part or the metal part is damaged, there is no need to replace the whole, and only the damaged part needs to be replaced, thereby saving the repair cost and reducing

[0009] the repair cost.

[0010] Preferably, for the convenience of understanding, the present invention discloses a specific connection method between the metal part and the bolt part. The metal part is provided with an installation slot, and through holes are opened on the surface of the installation slot; the bolt part includes a connection section and a threaded section, and a first threaded hole is opened on the surface of the connection section; wherein, when the connection section is inlaid in the installation slot, the through holes are aligned with the first threaded hole, and the bolt passes through the first threaded hole and the through holes. When installation is required, first inlay the connection section of the bolt part into the installation slot of the metal part, and then fix the positions of the metal part and the bolt part by passing the bolt through the first threaded hole and the through holes. This connection method is relatively safe. When the first structural member and the second structural member rotate relative to each other, the bolt part will not rotate relative to the metal part, thus avoiding safety accidents.

[0011] Preferably, in order to prevent rotation between the first structural member and the second structural member after the installation of the first structural member and the second structural member, a second groove is also provided at one end of the metal member where the installation groove is opened. An elastic member and a limiting post are arranged inside the cavity of the second groove. The elastic member acts on the limiting post, and the material of the limiting post is magnetic metal. A limiting groove is provided on the surface of the first structural member, and the limiting groove is aligned with the limiting post. During installation, the limiting post contracts into the second groove under the action of the magnetic force of the installation tool. At this time, the first structural member and the second structural member are in a rotatable state. After the installation of the first structural member and the second structural member is completed, the magnetic force is no longer used to adsorb the limiting post. At this time, the limiting post moves towards the limiting groove under the action of the elastic member, and a part of it is inserted into the limiting groove. At this time, the first structural member and the second structural member are in a non-rotatable state. Among them, the structure of the limiting post can be designed as two cylinders with different thicknesses connected in sequence. The thick cylinder is arranged to slide inside the second groove, and the thin cylinder can pass through the second groove and extend to the outside.

[0012] Preferably, for the convenience of maintenance, the first structural member can also be replaced for maintenance. The first structural member includes a first metal member and a second metal member detachably connected to the first metal member. The limiting groove is provided on the surface of the first metal member, and the threaded hole is arranged on the surface of the second metal member.

[0013] The present invention also discloses an installation method for a bolt assembly for installing the bolt assembly. The installation method includes the following steps:

[0014] S101: Completely embed the first structural member in the first object, and embed the bearing of the second structural member in the second object;

[0015] S102: Align the bolt part with the threaded hole on the surface of the first structural member, fix the first object, and install the installation tool on the surface of the second object. The installation tool includes a motor and a magnetic adsorption mechanism driven by the motor to rotate;

[0016] S103: The magnetic adsorption mechanism adsorbs the metal member, and the motor drives the magnetic adsorption mechanism and the metal member to rotate;

[0017] S104: While performing step S103, the magnetic adsorption mechanism adsorbs the limiting post, and the limiting post contracts into the second groove;

[0018] S105: When the installation of the bolt part is completed, the limiting post is aligned with the limiting groove. Remove the installation tool from the surface of the second object. The limiting post moves towards the first metal member under the action of the elastic member, so that the limiting post is embedded in the limiting groove, and the installation of the bolt assembly is completed.

[0019] When the bolt assembly needs to be disassembled, the installation tool is placed on the surface of the second object. At this time, the limiting post is adsorbed into the limiting groove again. The driving motor is driven, and the motor drives the magnetic adsorption mechanism to rotate. Further, the magnetic adsorption mechanism drives the metal part to rotate, and the bolt part is disassembled from the first structural member.

[0020] Preferably, in order to facilitate the easy insertion of the limiting post when the limiting post is not adsorbed, the size of the limiting post is smaller than the size of the limiting groove.

[0021] Preferably, for easy understanding, the specific structure of the magnetic adsorption mechanism is disclosed in the present invention. The magnetic adsorption mechanism is an electromagnet. The installation tool further includes a bracket for supporting the motor and a power supply device for supplying power to the magnetic adsorption mechanism. One end of the power supply device is connected to the motor shaft part, and the other end is connected to the magnetic adsorption mechanism.

[0022] Preferably, in order to fix the positions of multiple installation tools at the same time, and then install or disassemble multiple bolt groups

[0023] The installation tool is connected to a support system. The support system includes a frame, at least two clamping mechanisms and a power supply device. The clamping mechanisms are arranged to be movably connected to the frame through a connecting component. The power supply device is arranged to supply power to the motor. Among them, at least two wire arrangement sockets are arranged on the surface of the power supply device. The clamping mechanisms can move positions on the surface of the frame, and then the positions of the installation tools can be adjusted. The power supply device supplies power to the motors at the same time, and then the installation tools start to work at the same time, which is convenient for installing the bolt assemblies on a plane.

[0024] Preferably, for easy understanding, the present invention also discloses the specific structure of a connecting component. The connecting component includes a sliding sleeve slidably connected to the frame. A second threaded through hole is formed on the surface of the sliding sleeve, and a second bolt member is threadedly connected to the second threaded hole.

[0035] The following provides a detailed description of the embodiments of the present invention. These embodiments are implemented on the premise of the technical solution of the present invention, and detailed implementation manners and specific operation processes are given. However, the protection scope of the present invention is not limited to the following embodiments.

[0036] Such as Figure 1As shown, the present invention discloses a bolt assembly that is not easy to disassemble, including a first structural member 1 with a threaded hole and a second structural member 2 arranged corresponding to the first structural member 1, the second structural member 2 includes a metal member 21, a bolt portion 22 and a bearing 26, the bolt portion 22 is arranged to be connected to the metal member 21 at one end, and the bearing 26 is arranged to be sleeved on the surface of the metal member 21, wherein the metal member 21 is a magnetic metal and is sleeved on an end away from the bolt portion 22.

[0037] Based on the above structure, for the bolt assembly in the present invention, the first structural member 1 and the second structural member 2 are connected to each other.

[0038] The parts are installed by matching each other, wherein when installation is required, a part is slotted and the first structural member 1 is installed.

[0039] Embedded in the groove, another part is also grooved, and the metal part 21 with the bearing 26 is embedded in the groove of the other part, so that the bolt part 22 is exposed relative to the groove, and the metal part 21 is rotated. The metal part 21 drives the bolt part 22 to rotate. The bolt part 22 rotates into the first structural member 1 during the rotation process, thereby completing the connection between the first structural member 1 and the second structural member 2. The bolt assembly in the present invention will not be exposed to the outside of the part after the installation is completed, thereby achieving an anti-disassembly effect.

[0040] In order to save maintenance costs and facilitate the maintenance and replacement between the bolt part 22 and the metal part 21, the bolt part

[0041] 2 and the metal part 21 are detachably connected. Because the price of the bolt assembly of the present invention is higher than that of the ordinary bolt assembly, if the cost of replacing and repairing the entire assembly is high, when the bolt part 22 or the metal part 21 is damaged, there is no need to replace the entire assembly, but only the damaged part, thereby saving the cost of repair and reducing the cost of maintenance.

[0042] For ease of understanding, the present invention discloses a specific embodiment of the connection between a metal member 21 and a bolt portion 22. As shown in the figure, the metal member 21 is provided with a mounting groove, and a through hole is provided on the surface of the mounting groove; the bolt portion 22 includes a connecting section and a threaded section, and a first threaded hole is provided on the surface of the connecting section; wherein, when the connecting section is embedded in the mounting groove, the through hole is aligned with the first threaded hole, and the bolt member 23 passes through the first threaded hole and the through hole. When installation is required, the connecting section of the bolt portion 22 is first embedded in the mounting groove of the metal member, and then the bolt member 23 passes through the first threaded hole and the through hole to fix the position of the metal member 21 and the bolt portion 22. This connection method is relatively safe. When the first structural member 1 and the second structural member 2 rotate relative to each other, the bolt portion 2 will not rotate relative to the metal member 21, thereby not causing a safety accident.

[0043] In order to further enhance the anti-disassembly effect of the bolt assembly in the present invention, after the installation of the first structural member 1 and the second structural member 2 is completed, rotation between the first structural member 1 and the second structural member 2 will not occur, as Figure 2 and Figure 3 shown, at one end of the metal member 21 where the installation groove is opened, a second groove body is also opened. Inside the cavity of the second groove body, an elastic member 24 and a limiting post 25 are arranged. The elastic member 24 acts on the limiting post 25, and the material of the limiting post 25 is magnetic metal; a limiting groove 111 is opened on the surface of the first structural member 1, and the limiting groove 111 is aligned with the limiting post 25. During installation, the limiting post 25 contracts into the second groove body under the action of the magnetic force of the installation tool. At this time, the first structural member 1 and the second structural member 2 are in a rotatable state. After the installation of the first structural member 1 and the second structural member 2 is completed, the limiting post 25 is no longer adsorbed by magnetic force. At this time, the limiting post 25 moves towards the limiting groove 111 under the action of the elastic member 24, and a part of it is inserted into the limiting groove 111. At this time, the first structural member 1 and the second structural member 2 are in a non-rotatable state. Among them, the structure of the limiting post 25 can be designed as two cylinders with different thicknesses connected in sequence. The thick cylinder is arranged to slide in the second groove body, and the thin cylinder can pass through the second groove body and extend to the outside.

[0044] Among them, in order to facilitate maintenance, the first structural member 1 can also be repaired and replaced. As Figure 1 shown, the first structural member 1 includes a first metal member 11 and a second metal member 12 detachably connected to the first metal member 11. The limiting groove 111 is opened on the surface of the first metal member 11, and threaded holes are arranged on the surface of the second metal member 12.

[0045] The present invention also discloses an installation method for a bolt assembly, which is used to install the bolt assembly. The installation method includes the following steps:

[0046] S101: Completely embed the first structural member 1 in the first object, and embed the bearing 26 of the second structural member 2 in the second object;

[0047] S102: Align the bolt part 22 with the threaded hole on the surface of the first structural member 1, fix the first object, and install the installation tool 3 on the surface of the second object. The installation tool 3 includes a motor 31 and a magnetic adsorption mechanism 34 driven by the motor 31 to rotate;

[0048] S103: The magnetic adsorption mechanism 34 adsorbs the metal member 21, and the motor 31 drives the magnetic adsorption mechanism 34 and the metal member 21 to rotate;

[0049] S104: While performing step S103, the magnetic adsorption mechanism 34 adsorbs the limiting post 25, and the limiting post 25 contracts into the second groove body;

[0050] S105: When the installation of the bolt part is completed, the limit post 25 is aligned with the limit groove 111. The installation tool 3 is removed from the surface of the second object. Under the action of the elastic member 24, the limit post 25 moves towards the first metal part 11, so that the limit post 25 is embedded in the limit groove 11, completing the installation of the bolt assembly. Among them, when the installation of the bolt part is completed, the metal part 21 cannot rotate continuously. At this time, the adsorption force existing between the magnetic adsorption mechanism 34 and the metal part 21 becomes the resistance to the rotation of the motor 31. When the technician finds that the rotation of the motor 31 is abnormal, it means that the installation of the bolt part is completed. At this time, there is no need to rotate the metal part 21 through the installation tool 3 anymore, and only need to stop supplying power to the motor 31.

[0051] When the bolt assembly needs to be disassembled, the installation tool 3 is placed on the surface of the second object again. At this time, the limit post 2 is adsorbed into the limit groove 111 again. The driving motor 31 is driven, and the motor 31 drives the magnetic adsorption mechanism 34 to rotate. Furthermore, the magnetic adsorption mechanism 34 drives the metal part 21 to rotate, disassembling the bolt part 22 from the first structural part 1. In order to facilitate the easy insertion of the limit post 25 when it is not adsorbed, the size of the limit post 25 is smaller than the size of the limit groove 111.

[0052] For easy understanding, the present invention discloses a specific embodiment of the structure of the magnetic adsorption mechanism 34, as Figure 5 shown. The magnetic adsorption mechanism 34 is an electromagnet. The installation tool 3 further includes a bracket 32 for supporting the motor 31 and a power supply device 33 for supplying power to the magnetic adsorption mechanism 34. One end of the power supply device 33 is connected to the shaft part of the motor 31, and the other end is connected to the magnetic adsorption mechanism 34. For the bracket 32, it is arranged in a "concave" shape. A motor is fixedly installed at its concave part, and a cooling fan is also arranged at its concave part to dissipate heat from the motor 3. Moreover, by controlling the energization or de-energization of the electromagnet, it is convenient to control whether the magnetic adsorption mechanism 34 adsorbs the metal part 21.

[0053] Among them, in order to fix the positions of multiple installation tools 3 at the same time, and thus install or disassemble multiple bolt assemblies, the present invention also discloses a support system 4, as Figure 4 and Figure 6As shown, the installation tool 3 is connected to the support system 4. The support system 4 includes a frame body 41, at least two clamping mechanisms 42, and a power supply device 43. The clamping mechanisms 42 are arranged to be movably connected to the frame body 41 through a connection component. The power supply device 43 is arranged to supply power to the motor 31. Among them, at least two cable sockets are arranged on the surface of the power supply device 43. The clamping mechanisms 42 can move positions on the surface of the frame body 41, and thus the position of the installation tool 3 can be adjusted. The power supply device 43 supplies power to the motor 31 at the same time, and thus the installation tool 3 starts to work simultaneously, facilitating the installation of bolt components on a plane. Among them, the present invention also discloses a specific structure of the connection component. In the figure, the connection component includes a sliding sleeve 441 slidably connected to the frame body 41. A second threaded through hole is provided on the surface of the sliding sleeve 441, and a second bolt member 442 is threadedly connected to the second threaded through hole.

[0054] The present invention discloses a specific method for installing parts through bolt components to facilitate public understanding. For example Figure 7 as shown, in Figure 7 , the position marked at a is the tabletop, and the position marked at b is the table leg. The installation of the tabletop and the table leg is completed through bolt components. A groove is provided on the surface of the tabletop, and the groove is provided at the position c. The second structural member 2 is embedded in the groove. The table leg is also provided with a groove, and the first structural member 1 is completely embedded in the groove of the table leg. The metal member 21 is set in a cylindrical shape, and the size of the outer wall of the metal member 21 is the same as the size of the inner wall of the groove of the table leg. When the metal member 21 is embedded in the groove of the table leg, the bolt portion 22 and the threaded hole are aligned, and thus the stability during the installation process can be improved. By rotating the metal member 21 with the installation tool 3, the first structural member 1 and the second structural member 2 can be connected together to complete the installation.

[0055] In summary, compared with the prior art, the bolt components in the present invention are hidden in the parts after installation, which is more beautiful, and it is not easy for non-technical personnel to disassemble them with traditional tools, and the safety factor is high.

[0056] The above is only a preferred specific embodiment of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present invention, according to the technical solution and inventive concept of the present invention, makes equivalent replacements or changes, and should be covered by the protection scope of the present invention.

[0057] It should be noted that in this article, relational terms such as first and second are only used to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply a relationship between these entities or operations

[0058] There is no such actual relationship or sequence. Moreover, the terms "comprising", "including" or any other variant thereof are intended to cover non-exclusive inclusion, such that a process, method, article or apparatus that comprises a series of elements includes not only those elements but also other elements not expressly listed, or elements that are inherent to such process, method, article or apparatus. Without further limitation, an element defined by the statement "comprising an..." does not exclude the presence of additional identical elements in the process, method, article or apparatus that comprises the element.
