Description
Technical Field
[0001] This utility model relates to the field of connection structure technology, specifically to a structure and auxiliary disassembly device for making it difficult for users to disassemble products without authorization. Background Technology
[0002] Some products have a casing that encloses the internal structure to prevent user damage. The casing is typically attached to the internal structure using ordinary screws. Specifically, when using screws, the screws are passed through mounting holes on the casing and then screwed into threaded holes on the internal structure. With this existing casing connection method, users can easily disassemble the casing using common tools (such as screwdrivers and wrenches), meaning users can easily disassemble the product themselves.
[0003] To reduce the possibility of product damage caused by users disassembling the product themselves, fragile stickers are usually affixed to the seams or screw holes of the product casing. The fragile stickers are printed with the words "tear to remove invalid" and the instruction manual, warranty terms or contract states that disassembly is prohibited, otherwise the warranty will be voided. However, this method lacks technical binding force, and users can still easily disassemble the product. Utility Model Content
[0004] In view of this, the purpose of this utility model is to provide a structure and auxiliary disassembly device for making it difficult for users to disassemble products without authorization, so as to solve the technical problem that existing methods for reducing the possibility of users disassembling products without authorization lack technical constraints and users can still easily disassemble products.
[0005] This utility model is achieved through the following technical solution:
[0006] A structure designed to prevent users from easily disassembling a product includes a cylinder, a cylindrical shell, a regular hexagonal prism, a screw, and a fixing part. The front end of the cylinder is used to fix and connect to the product shell. The cylinder mates with the inner cavity of the cylinder, and the cylinder has a cavity. The rear side wall of the cavity has a through hole communicating with the middle of the rear end face of the cylinder. The rear end of the regular hexagonal prism protrudes from the rear end of the cylinder and is slidably fitted within the through hole. The rear end of the screw is fixed to the middle of the front end face of the cylinder. The fixing part is located within the cavity and is used to fix the regular hexagonal prism when the rear end face of the regular hexagonal prism is flush with the rear end face of the cylinder.
[0007] Furthermore, the cavity has a cylindrical structure that is coaxial with the cylinder.
[0008] The fixing part includes a limiting member, a disc, and a rubber ring. The limiting member is fixed in the cavity. The disc is fixedly connected to the front end of the regular hexagonal prism. When the disc abuts against the limiting member, the rear end face of the regular hexagonal prism is flush with the rear end face of the cylinder. The outer circumference of the disc is recessed inward to form an annular groove. The rubber ring is located in the annular groove and is interference-fitted with the annular groove. The rubber ring is also interference-fitted with the cavity.
[0009] Furthermore, it also includes an exhaust channel, which is disposed on the cylinder and is used to discharge air from the portion of the cavity located in front of the rubber ring.
[0010] Furthermore, the exhaust channel includes a groove and a connecting hole. The groove is formed by recessing from the rear end of the cylinder and is cylindrical in shape with the cylinder as the center line. The groove is arranged around the cavity. The connecting hole is located on the inner side wall of the groove. The outer end of the connecting hole is connected to the front end of the groove, and the inner end is connected to the front end of the cavity.
[0011] Furthermore, a slot is formed by an inward recess in the middle of one side of the regular hexagonal prism. The slot is located on the rear side of the rear end face of the cylinder. A plug rod is inserted into the slot. The plug rod is arranged perpendicular to the axis of the cylinder, and one end of the plug rod is located outside the slot.
[0012] Furthermore, a circular groove is formed in the middle of one side of the regular hexagonal prism, and a rubber tube that mates with the circular groove is provided in the circular groove. The outer circumferential surface of the rubber tube is fixedly connected to the groove wall of the circular groove, and the inner cavity of the rubber tube forms the slot. The insertion rod is interference-fitted with the inner cavity of the rubber tube.
[0013] Furthermore, the end of the insert located within the slot gradually narrows and forms a frustum-shaped structure.
[0014] This utility model also provides an auxiliary disassembly device for assisting in the disassembly of the aforementioned structure designed to prevent users from disassembling the product themselves. The device includes a round rod, an air pump, and a connecting pipe. The diameter of the round rod matches the diameter of the inner cavity of the cylinder. The center of the front end face of the round rod is recessed to form a receiving groove for accommodating the regular hexagonal prism. The front end face of the round rod, corresponding to the position of the groove, is recessed to form an air supply groove. The air supply groove is cylindrical and surrounds the receiving groove, adapting to the groove. One end of the connecting pipe is fixedly connected to the round rod and communicates with the air supply groove, while the other end is fixedly connected to the air outlet of the air pump.
[0015] Furthermore, a first and a second annular rubber pad are fixed on the front end face of the round rod. The outer circumferential surface of the first rubber pad is flush with the inner circumferential surface of the air supply groove, and the inner circumferential surface of the second rubber pad is flush with the outer circumferential surface of the air supply groove.
[0016] Furthermore, an exhaust hole is formed on the round rod, with one end connected to the receiving groove and the other end connected to the outer surface of the round rod.
[0017] The beneficial effects of this utility model are as follows:
[0018] After the outer shell of the product is installed on the internal structure of the product using the structure described in this utility model, which makes it difficult for the user to disassemble the product, the cylinder is completely located inside the cylindrical shell. The rear end face of the regular hexagonal prism remains flush with the rear end face of the cylinder. It is not easy for the user to apply force to the regular hexagonal prism and the cylinder for rotating the screw. The mechanical structure can restrain the user, making it difficult for the user to disassemble the product.

[0031] Therefore, the following detailed description of the embodiments of the present invention provided in the accompanying drawings is not intended to limit the scope of the claimed invention, but merely to illustrate selected embodiments of the invention. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without inventive effort are within the scope of protection of the present invention.
[0032] It should be noted that similar labels and letters in the following figures indicate similar items. Therefore, once an item is defined in one figure, it does not need to be further defined and explained in subsequent figures.
[0033] In the above description of this utility model, it should be noted that the terms "one side," "the other side," etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, or the orientation or positional relationship commonly used when the product of this utility model is in use. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model. In addition, the terms "first," "second," etc., are only used to distinguish descriptions and should not be construed as indicating or implying relative importance.
[0034] Furthermore, terms such as "identical" do not imply that components must be absolutely identical; minor differences are permissible. The term "perpendicular" simply means that the positional relationship between components is more perpendicular than "parallel," not that the structure must be perfectly perpendicular; a slight tilt is acceptable.
[0035] Please see Figure 1-5 This utility model provides a technical solution: a structure for making it difficult for users to disassemble a product without authorization, including a cylinder 1, a cylindrical column 2, a regular hexagonal prism 3, a screw 4, and a fixing part. The front end of the cylinder 1 is used to fix and connect the outer shell of the product. The cylindrical column 2 is fitted with the inner cavity of the cylinder 1. The cylindrical column 2 has a cavity 5 inside. The rear side wall of the cavity 5 has a through hole that connects to the middle of the rear end face of the cylindrical column 2. The rear end of the regular hexagonal prism 3 protrudes from the rear end of the cylindrical column 2. The regular hexagonal prism 3 is slidably fitted in the through hole. The rear end of the screw 4 is fixed to the middle of the front end face of the cylindrical column 2. The fixing part is located in the cavity 5 and is used to fix the regular hexagonal prism 3 when the rear end face of the regular hexagonal prism 3 is flush with the rear end face of the cylindrical column 2.
[0036] In this design, the length of the cylinder 1 is not less than the length of the cylinder 2, so that the cylinder 2 can be completely located inside the cylinder 1.
[0037] When the structure described in this utility model, which makes it difficult for users to disassemble the product without authorization, is in its initial state, the rear end of the regular hexagonal prism 3 protrudes beyond the rear end of the cylinder 2.
[0038] When manufacturing the outer shell of the product, the front end of the cylinder 1 in the structure of this utility model that makes it difficult for users to disassemble the product on their own is welded and fixed to the outer shell of the product, so that the mounting holes for mounting screws on the outer shell are located in the middle of the cylinder 1.
[0039] When connecting the outer shell of the product to its internal structure, align the mounting holes for screws on the outer shell with the corresponding screw holes on the internal structure. Then, align the front end of the screw 4 with the mounting hole and insert it into the screw hole position on the internal structure. Next, place a socket wrench adapted to the regular hexagonal prism 3 on the regular hexagonal prism 3. Rotate the regular hexagonal prism 3 with the socket wrench. The regular hexagonal prism 3 drives the cylinder 2 and the screw 4 to rotate, causing the screw 4 to move forward and enter the screw hole. After the screw 4, cylinder 2, and regular hexagonal prism 3 have moved forward a certain distance, the screw 4 can be tightened in the screw hole, and the cylinder 2 can be completely inserted into the cylinder 1. The front end of the cylinder 2 can abut against and press against the surface of the outer shell of the product, and the rear end face of the cylinder 2 will not protrude from the rear end face of the cylinder 1. Then, the socket wrench is removed from the regular hexagonal prism 3, and the regular hexagonal prism 3 is pushed forward. After the regular hexagonal prism 3 moves forward a certain distance, the rear end face of the regular hexagonal prism 3 becomes flush with the rear end face of the cylinder 2. At this point, the fixing part secures the regular hexagonal prism 3, preventing it from moving back and forth, and ensuring that the rear end face of the regular hexagonal prism 3 remains flush with the rear end face of the cylinder 2. This allows the outer shell of the product to be installed on the internal structure of the product.
[0040] After the outer shell of the product is installed on the internal structure of the product using the structure described in this utility model, which makes it difficult for the user to disassemble the product, the cylinder 2 is completely located inside the cylinder 1, and the rear end face of the regular hexagonal prism 3 remains flush with the rear end face of the cylinder 2. It is not easy for the user to apply force to the regular hexagonal prism 3 and the cylinder 2 for rotating the screw 4. The mechanical structure can restrain the user, making it difficult for the user to disassemble the product.
[0041] In this embodiment, the cavity 5 has a cylindrical structure that is coaxial with the cylinder 2;
[0042] The fixing part includes a limiting member 6, a disc 7, and a rubber ring 8. The limiting member 6 is fixedly disposed in the cavity 5. The disc 7 is fixedly connected to the front end of the regular hexagonal prism 3. When the disc 7 abuts against the limiting member 6, the rear end face of the regular hexagonal prism 3 is flush with the rear end face of the cylinder 2. The outer circumference of the disc 7 is recessed inward to form an annular groove. The rubber ring 8 is located in the annular groove and is interference-fitted with the annular groove. The rubber ring 8 is also interference-fitted with the cavity 5.
[0043] The limiting member 6 is specifically a limiting post. The front end of the limiting post is fixedly connected to the middle of the front sidewall of the cavity 5. When the disc 7 moves forward to abut the rear end of the limiting post, the rear end face of the regular hexagonal prism 3 is flush with the rear end face of the cylinder 2. Specifically, the distance from the rear end face of the regular hexagonal prism 6 to the rear end face of the cylinder 2 is equal to the distance from the front end face of the disc 7 to the rear end face of the limiting post.
[0044] The structure of this utility model for making it difficult for users to disassemble the product without authorization also includes an exhaust channel, which is provided on the cylinder 2 and is used to discharge the air in the part of the cavity 5 located in front of the rubber ring 8.
[0045] When the structure described in this utility model, which makes it difficult for users to disassemble the product without authorization, is in its initial state, the rear end of the regular hexagonal prism 3 protrudes beyond the rear end of the cylinder 2. Under the frictional force between the outer circumferential surface of the rubber ring 8 and the side wall of the cavity 5, the disc 7 and the regular hexagonal prism 3 are not easy to slide freely in the through hole.
[0046] When the regular hexagonal prism 3 needs to slide forward, a thrust is provided to the regular hexagonal prism 3 to overcome the friction between the outer peripheral surface of the rubber ring 8 and the side wall of the cavity 5, thus enabling the regular hexagonal prism 3 to slide forward within the through hole. During the forward sliding process of the regular hexagonal prism 3, the regular hexagonal prism 3 pushes the disk 7 and the rubber ring 8 to slide forward within the cavity 5. When the disk 7 abuts against the limiting member 6, the disk 7, the rubber ring 8, and the regular hexagonal prism 3 cannot continue to slide forward. Under the action of the friction between the outer peripheral surface of the rubber ring 8 and the side wall of the cavity 5, the disk 7, the rubber ring 8, and the regular hexagonal prism 3 are not easy to slide backward. At this time, the rear end face of the regular hexagonal prism 3 can remain flush with the rear end face of the cylinder 2. The fixing part can thus fix the regular hexagonal prism 3 when the rear end face of the regular hexagonal prism 3 is flush with the rear end face of the cylinder 2.
[0047] As the disc 7 and the rubber ring 8 slide forward within the cavity 5, the air in the portion of the cavity 5 located in front of the rubber ring 8 can be discharged through the exhaust channel, so that the air pressure in the portion of the cavity 5 located in front of the rubber ring 8 will not increase, and the disc 7 and the rubber ring 8 will not be resisted by the air pressure in the cavity 5 during the forward sliding process.
[0048] In this embodiment, the exhaust channel includes a groove 9 and a connecting hole 10. The groove 9 is formed by recessing from the rear end face of the cylinder 2. The groove 9 has a cylindrical structure with the center line of the cylinder 2. The groove 9 is arranged around the cavity 5. The connecting hole 10 is provided on the inner side wall of the groove 9. The outer end of the connecting hole 10 is connected to the front end of the groove 9, and the inner end is connected to the front end of the cavity 5.
[0049] As the disc 7 and the rubber ring 8 slide forward within the cavity 5, air in the portion of the cavity 5 located in front of the rubber ring 8 can be discharged sequentially through the connecting hole 10 and the groove 9. The exhaust channel thus discharges the air from the portion of the cavity 5 located in front of the rubber ring 8. Because the groove 9 is formed by a forward indentation from the rear end face of the cylinder 2, and the groove 9 has a cylindrical structure coaxial with the cylinder 2, it is difficult for the user to apply force to the cylinder 2 for rotating the screw 4 through the groove 9.
[0050] In this embodiment, a slot is formed by an inward recess in the middle of one side of the regular hexagonal prism 3. The slot is located on the rear side of the rear end face of the cylinder 2. A plug rod 11 is inserted into the slot. The plug rod 11 is arranged perpendicular to the axis of the cylinder 2, and one end of the plug rod 11 is located outside the slot.
[0051] In the initial state of the structure described in this utility model for preventing users from easily disassembling the product, the rear end of the regular hexagonal prism 3 protrudes beyond the rear end of the cylinder 2. The slot is located on the rear side of the rear end face of the cylinder 2, and one end of the insert rod 11 is inserted into the slot. The insert rod 11 is also located on the rear side of the rear end face of the cylinder 2. Before the screw 4 is screwed into the screw hole, if the regular hexagonal prism 3 is accidentally pressed forward, the insert rod 11 can act as a limit, preventing the regular hexagonal prism 3 from being completely pressed forward into the through hole.
[0052] When the socket wrench is placed on the regular hexagonal prism 3, it can be placed on the portion of the regular hexagonal prism 3 located behind the insert 11.
[0053] After the screw 4 is tightened into the screw hole and the cylinder 2 is fully inserted into the cylinder 1, the socket wrench is removed from the regular hexagonal prism 3, and then the insert rod 11 is pulled out from the slot. Then the regular hexagonal prism 3 can be pushed forward so that the rear end face of the regular hexagonal prism 3 is flush with the rear end face of the cylinder 2.
[0054] In this embodiment, a circular groove is formed in the middle of one side of the regular hexagonal prism 3. A rubber tube 12 that mates with the circular groove is provided in the circular groove. The outer circumferential surface of the rubber tube 12 is fixedly connected to the groove wall of the circular groove. The inner cavity of the rubber tube 12 forms the slot. The insertion rod 11 is interference-fitted with the inner cavity of the rubber tube 12.
[0055] Because the insertion rod 11 is interference-fitted with the inner cavity of the rubber tube 12, after the insertion rod 11 is inserted into the inner cavity of the rubber tube 12, the insertion rod 11 can expand tightly within the inner cavity of the rubber tube 12, making it difficult for the insertion rod 11 to accidentally come out of the rubber tube 12 and to accidentally fall off the regular hexagonal prism 3. When it is necessary to pull out the insertion rod 11, it is only necessary to apply a pulling force that can overcome the friction between the outer circumferential surface of the insertion rod 11 and the inner circumferential surface of the rubber tube 12, and the insertion rod 11 can be pulled out of the rubber tube 12.
[0056] In this embodiment, the end of the insertion rod 11 located in the slot gradually narrows and forms a frustum-shaped structure 13.
[0057] When inserting the rod 11 into the slot, the smaller end of the frustum-shaped structure 13 on the rod 11 enters the slot first. Then, guided by the conical surface on the frustum-shaped structure 13, the rod 11 can be accurately inserted into the slot, making it easier to insert the rod 11 into the slot accurately.
[0058] Please see Figure 6-9 This utility model also provides another technical solution: an auxiliary disassembly device for assisting in the disassembly of the aforementioned structure designed to prevent users from easily disassembling the product themselves. It includes a round rod 14, an air pump (not shown in the figure), and a connecting pipe 15. The air pump can be an MDF-8805 air pump. The diameter of the round rod 14 matches the inner diameter of the cylinder 1. The center of the front end face of the round rod 14 is recessed rearward to form a receiving groove 16 for accommodating the regular hexagonal prism 3. The front end face of the round rod 14 corresponds to the recessed... A gas supply groove 17 is formed by a rearward indentation at the location of groove 9. The gas supply groove 17 is cylindrical and is arranged around the receiving groove 16. The gas supply groove 17 is adapted to the groove 9, that is, the diameter of the outer circumferential surface of the gas supply groove 17 is the same as the diameter of the outer circumferential surface of the groove 9, and the diameter of the inner circumferential surface of the gas supply groove 17 is the same as the diameter of the inner circumferential surface of the groove 9. One end of the connecting pipe 15 is fixedly connected to the round rod 14 and communicates with the gas supply groove 17, and the other end is fixedly connected to the air outlet of the air pump.
[0059] When the product malfunctions and requires internal structural repair, the product should be sent to the manufacturer's product repair department. The repair department staff will disassemble the aforementioned structure designed to prevent users from disassembling the product themselves and inspect the internal structure.
[0060] When product repair personnel disassemble the aforementioned structure designed to prevent users from easily disassembling the product: First, insert the front end of the round rod 14 forward into the cylinder 1, with the front end of the round rod 14 abutting against the rear end face of the cylinder 2. At this time, the receiving groove 16 is aligned with the through hole, and the air supply groove 17 is aligned with the groove 9. Then, push the round rod 14 forward by hand and start the air pump. The air discharged from the air pump outlet enters the cavity 5 sequentially through the air supply groove 17, the groove 9, and the connecting hole 10. The air pressure in the cavity 5 increases. Under the action of the air pressure in the cavity 5, the disc 7 and the rubber ring 8 can be pushed backward. The disc 7 and the rubber ring 8 can push the regular hexagonal prism 3 backward, causing the rear end of the regular hexagonal prism 3 to protrude again from the rear end face of the cylinder 2 and enter the receiving groove 16. Then, turn off the air pump and pull the round rod 14 out of the cylinder 1. Then, a socket wrench is placed on the portion of the regular hexagonal prism 3 that protrudes from the rear end face of the cylinder 2, and the socket wrench is rotated. The socket wrench causes the regular hexagonal prism 3 to rotate, which in turn causes the cylinder 2 and the screw 4 to rotate, causing the screw 4 to move backward within the screw hole in the internal structure of the product. After the screw 4 has moved backward a certain distance, it disengages from the screw hole in the internal structure of the product, thus completing the disassembly of the structure designed to prevent the user from easily disassembling the product.
[0061] The manufacturer only provides the aforementioned auxiliary disassembly device to its product repair department, and not to users.
[0062] In this embodiment, a first annular rubber pad 18 and a second rubber pad 19 are fixed on the front end face of the round rod 14. The outer peripheral surface of the first rubber pad 18 is flush with the inner peripheral surface of the air supply groove 17, and the inner peripheral surface of the second rubber pad 19 is flush with the outer peripheral surface of the air supply groove 17.
[0063] The first rubber pad 18 and the second rubber pad 19 can seal the gap between the front end face of the round rod 14 and the rear end face of the cylinder 2, so that the air entering the air supply groove 17 from the air pump outlet is not easy to leak out between the front end face of the round rod 14 and the rear end face of the cylinder 2.
[0064] In this embodiment, the round rod 14 has an exhaust hole 20 with one end connected to the receiving groove 16 and the other end connected to the outer surface of the round rod 14. When air is injected into the cavity 5, during the process of the regular hexagonal prism 3 moving backward and entering the receiving groove 16, the air in the receiving groove 16 can be discharged from the exhaust hole 20, so that the air pressure in the receiving groove 16 will not increase, and the air in the receiving groove 16 will not cause resistance to the backward movement of the disc 7 and the rubber ring 8, making it easier for the disc 7, the rubber ring 8 and the regular hexagonal prism 3 to move backward.
[0065] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of this utility model without departing from the spirit and scope of the technical solutions of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
