When the separation of the first part (200) from the second part (300) is required, the threaded fastener (110) is rotated and withdrawn from the threaded mounting hole (140). The washer (120) is in an anti-retreat fit with the threaded fastener (110), and therefore the washer (120) can limit the threaded fastener (110), thereby preventing the threaded fastener (110) from retreating from the mounting through hole (130).

Description

Fastening components, fixed installation structures and product equipment Technical Field

[0001] This application relates to the field of mechanical technology, and in particular to a fastening component, a fixed installation structure, and product equipment. Background Technology

[0002] In the assembly of products and equipment, such as lithium battery devices, it is common to fasten two parts together with bolts. During subsequent use, it is necessary to frequently remove the bolts and separate the connected parts to facilitate maintenance and repair. However, bolts are prone to rolling off after disassembly, making them difficult to find during reassembly and thus affecting disassembly and assembly efficiency.

[0003] Application content

[0004] Therefore, it is necessary to provide a fastening component, a fixed installation structure, and product equipment that can improve the efficiency of disassembly and assembly to address the above problems.

[0005] A fastening assembly includes a threaded fastener and a washer. The threaded fastener includes a head and a shank extending from one side of the head. The shank includes a smooth section near the head and a threaded section away from the head. The washer has a threaded through hole through which the threaded fastener passes, and the threaded section is threadedly engaged with the threaded through hole.

[0006] A fixed mounting structure is provided for connecting a first part and a second part. The fixed mounting structure includes a threaded fastener, a washer, a mounting through hole in the first part, and a threaded mounting hole in the second part. The washer is capable of being clamped between the first part and the second part. The threaded fastener can pass through the mounting through hole and the washer in sequence and be screwed into the threaded mounting hole to fix the first part to the second part. The washer and the threaded fastener are anti-reversely engaged along the extension direction of the threaded fastener.

[0007] In one embodiment, the gasket has a threaded through hole through which the threaded fastener passes, and the threaded fastener can engage with the threaded through hole as it passes through the threaded through hole to achieve a non-reverse engagement with the gasket.

[0008] In one embodiment, the threaded fastener includes a head and a shank extending from one side of the head. The shank includes a smooth section near the head and a threaded section away from the head. The threaded section can pass through the mounting through hole and the threaded through hole in sequence and be screwed into the threaded mounting hole, and the smooth section passes through the threaded through hole.

[0009] In one embodiment, the outer diameter of the smooth rod segment is smaller than the outer diameter of the threaded segment.

[0010] In one embodiment, the gasket is annular, and the threaded through hole is coaxially arranged with the gasket.

[0011] In one embodiment, the threaded fastener includes a head and a screw extending from one side of the head, the screw being capable of passing sequentially through the mounting through hole and the threaded through hole and being screwed into the threaded through hole and the threaded mounting hole.

[0012] In one embodiment, the gasket is configured as a ring with a notch, and the threaded fastener can be engaged with the gasket through the notch to achieve a non-retractable engagement with the gasket.

[0013] In one embodiment, the threaded fastener includes a head and a shank extending from one side of the head. The shank includes a smooth section near the head and a threaded section away from the head. The outer diameter of the smooth section is smaller than the outer diameter of the threaded section. The threaded fastener can be engaged with the washer through the notch, and the washer is loosely fitted onto the smooth section.

[0014] In one embodiment, the threaded fastener includes a head and a shank extending from one side of the head. The shank includes a smooth section near the head and a threaded section away from the head. The outer diameter of the smooth section is smaller than the outer diameter of the threaded section. The threaded fastener can be engaged with the washer through the notch, and the washer is press-fitted with the smooth section.

[0015] In one embodiment, the threaded fastener includes a head and a screw extending from one side of the head, the threaded fastener being able to engage the washer through the notch and to cause the washer to have an interference fit with the screw.

[0016] In one embodiment, the mounting hole is configured as a light hole.

[0017] A product device includes a first part, a second part, and a fixing installation structure as described in any of the preferred embodiments above, or a fastening assembly as described in the embodiments above, wherein the first part and the second part are fixedly connected by the fixing installation structure or the fastening assembly.

[0018] In one embodiment, the first part is configured as a plastic component.

[0019] In one embodiment, the product device is a lithium battery device, the first part is a housing, and the second part is a frame.

[0020] In the aforementioned fixed installation structure and product equipment, threaded fasteners pass sequentially through the mounting through-hole and the washer, and are screwed into the threaded mounting hole to connect the first and second parts. When it is necessary to separate the first and second parts, the threaded fastener is rotated and pulled out of the threaded mounting hole. Because the washer and the threaded fastener have a locking mechanism, the washer can limit the threaded fastener, preventing it from exiting the mounting through-hole. Thus, the disassembled threaded fastener remains on the first part, preventing it from rolling off. During reassembly, the threaded fastener can be quickly screwed into the threaded mounting hole, thereby improving disassembly and assembly efficiency. Attached Figure Description

[0033] Please refer to Figure 1. This application provides a product device 10 and a fixed installation structure 100. The product device 10 includes a first part 200 and a second part 300, and the first part 200 and the second part 300 are fixedly connected by the fixed installation structure 100.

[0034] The aforementioned product equipment 10 can be lithium battery equipment, electrical equipment, mechanical automation equipment, and other equipment commonly found in production and daily life. For lithium battery equipment, the first part 200 can be a housing, and the second part 300 can be a frame. Typically, the housing, which is the first part 200, is molded from plastic materials such as PVC and is a plastic component.

[0035] Please refer to Figure 2. In one embodiment of this application, the fixed installation structure 100 includes a threaded fastener 110, a washer 120, a mounting through hole 130, and a threaded mounting hole 140.

[0036] A mounting through hole 130 is formed on the first part 200, and a threaded mounting hole 140 is formed on the second part 300. The first part 200 and the second part 300 can be installed using one fixed mounting structure 100 or multiple fixed mounting structures 100. Correspondingly, one or more mounting through holes 130 and threaded mounting holes 140 are formed on the first part 200 and the second part 300, respectively.

[0037] The washer 120 can be clamped between the first part 200 and the second part 300. The threaded fastener 110 can pass through the mounting hole 130 and the washer 120 in sequence and be screwed into the threaded mounting hole 140 to fix the first part 200 to the second part 300. The washer 120 can be made of metal or plastic, preferably metal, which is wear-resistant and deformation-resistant. When assembling the product equipment 10, the threaded fastener 110 can be passed through the mounting hole 130 first, then the washer 120 can be placed on the end of the threaded fastener 110 that extends out of the mounting hole 130, and finally the threaded fastener 110 can be inserted into the threaded mounting hole 140 and gradually tightened.

[0038] Furthermore, the washer 120 and the threaded fastener 110 are locked in place along the extension direction of the threaded fastener 110. That is, without applying external force to the washer 120, rotating the threaded fastener 110 will not cause the washer 120 to fall off the threaded fastener 110.

[0039] When product equipment 10 needs maintenance, the first part 200 and the second part 300 can be separated by rotating the threaded fastener 110 and removing it from the threaded mounting hole 140. As shown in Figure 3, because the washer 120 is in a locking fit with the threaded fastener 110, the washer 120 will remain on the threaded fastener 110 during the process of removing the threaded fastener 110 from the threaded mounting hole 140. In this way, the washer 120 can limit the threaded fastener 110, thereby preventing the threaded fastener 110 from exiting from the mounting through hole 130. That is to say, the disassembled threaded fastener 110 will still remain on the first part 200, so the threaded fastener 110 is not easy to roll off. During reassembly, the threaded fastener 110 can be quickly screwed into the threaded mounting hole 140 to fix the first part 200 to the second part 300, thereby improving the disassembly and assembly efficiency.

[0040] To address the issue of the threaded fastener 110 easily rolling off after disassembly, the applicant discovered that a threaded hole can also be provided on the first part 200 to mate with the threaded fastener 110 for installation. The threaded fastener 110 can be screwed into the threaded hole and then into the threaded mounting hole 140 on the second part 300, thereby fixing the first part 200 to the second part 300. Moreover, even after rotating the threaded fastener 110 and removing it from the threaded mounting hole 140, the threaded fastener 110 can still be screwed into the threaded hole of the first part 200 and remain on the first part 200. However, since the first part 200 (such as a cover) is usually made of plastic material such as PVC, creating a threaded hole can easily damage the first part 200, thereby affecting the service life of the product equipment 10.

[0041] Based on the above considerations, in order to solve the problem of threaded fasteners 110 easily rolling off after disassembly without affecting the service life of product equipment 10, the applicant, after in-depth research, designed a fixed installation structure 100. By adding a washer 120 that can engage with the threaded fastener 110 to prevent it from rolling back, the disassembled threaded fastener 110 can be placed on the first part 200. In this way, there is no need to drill a threaded hole on the first part 200, thus avoiding any adverse impact on the service life of product equipment 10.

[0042] Preferably, in this embodiment, the mounting through hole 130 is a smooth hole. That is, the inner wall of the mounting through hole 130 is smooth and does not have internal threads, so the threaded fastener 110 will not have a threaded engagement with the mounting through hole 130 when passing through it.

[0043] The gasket 120 and the threaded fastener 110 can achieve a lock-locking engagement through a threaded connection. Specifically, in this embodiment, the gasket 120 has a threaded through hole 121 through which the threaded fastener 110 passes, and the threaded fastener 110 can engage with the threaded through hole 121 during the process of passing through the threaded through hole 121 to achieve a lock-locking engagement with the gasket 120.

[0044] The internal thread of the threaded through hole 121 matches the external thread of the threaded fastener 110. When the threaded fastener 110 passes through the threaded through hole 121, if the washer 120 is to be removed from the threaded fastener 110, the washer 120 needs to be rotated relative to the threaded fastener 110 to overcome the blocking effect of the external thread on the surface of the threaded fastener 110. In this way, the engagement of the internal and external threads can prevent the washer 120 from retracting.

[0045] Please refer again to Figure 2 and also to Figure 4. In this embodiment, the threaded fastener 110 includes a head 111 and a shank 112 extending from one side of the head 111. The shank 112 includes a smooth shank section 1121 near the head 111 and a threaded section 1122 away from the head 111. The threaded section 1122 can pass through the mounting through hole 130 and the threaded through hole 121 in sequence and be screwed into the threaded mounting hole 140, while the smooth shank section 1121 passes through the threaded through hole 121.

[0046] The smooth section 1121 has no external threads on its surface, while the threaded section 1122 has external threads on its surface. During assembly of the product equipment 10, the threaded section 1122 passes through the mounting through hole 130 and then completely passes through the threaded through hole 121, finally extending into the threaded mounting hole 140 and screwed into it. The outer diameter of the threaded section 1122 is approximately equal to the inner diameter of the threaded through hole 121, and the threaded section 1122 can engage with it by thread when passing through the threaded through hole 121.

[0047] After the threaded fastener 110 is tightened to the correct position, the smooth section 1121 passes through the threaded through hole 121. Since the smooth section 1121 does not have external threads, there will be no threaded engagement between the threaded fastener 110 and the threaded through hole 121 after the product equipment 10 is assembled. Therefore, during the disassembly of the threaded fastener 110, rotating the threaded fastener 110 will not cause the washer 120 to unscrew along the threaded fastener 110, thus providing a better anti-reverse effect for the washer 120.

[0048] Furthermore, in this embodiment, the outer diameter of the smooth rod section 1121 is smaller than the outer diameter of the threaded section 1122. Since the outer diameter of the threaded section 1122 is approximately equal to the inner diameter of the threaded through hole 121, the outer diameter of the smooth rod section 1121 is also smaller than the inner diameter of the threaded section 1122. Thus, the washer 120 can be loosely fitted onto the smooth rod section 1121, preventing the washer 120 from rotating when the threaded fastener 110 is rotated, resulting in a better anti-reverse effect on the washer 120.

[0049] More specifically, in this embodiment, the gasket 120 is annular, and the threaded through hole 121 is coaxially arranged with the gasket 120. Therefore, after the threaded fastener 110 passes through the threaded through hole 121, the gasket 120 and the threaded fastener 110 will also be coaxially arranged, thus the gasket 120 has a better limiting effect on the threaded fastener 110.

[0050] Referring to Figure 5, in another embodiment, the threaded fastener 110 may also adopt a common bolt structure. Specifically, the threaded fastener 110 includes a head 111 and a screw 113 extending from one side of the head 111. The screw 113 can pass through the mounting through hole 130 and the threaded through hole 121 in sequence and be screwed into the threaded through hole 121 and the threaded mounting hole 140.

[0051] When disassembling the threaded fastener 110, initially, the washer 120, due to being clamped by the first part 200 and the second part 300, cannot rotate with the threaded fastener 110. This causes the washer to experience angular displacement relative to the rotating threaded fastener 110, and the washer 120 to retract a certain distance relative to the threaded fastener 110. However, as the threaded fastener 110 continues to rotate, once the first part 200 and the second part 300 become loose, the washer 120, having lost the clamping effect of the first part 200 and the second part 300, will rotate synchronously with the threaded fastener 110. At this point, the washer 120 has no angular displacement relative to the threaded fastener 110, and therefore will not continue to retract relative to the threaded fastener 110, thus achieving the purpose of preventing retraction.

[0052] In addition, the gasket 120 can also achieve a locking engagement with the threaded fastener 110 in other ways. For example, in one embodiment, the gasket 120 can be configured as a ring with a notch (not shown), and the threaded fastener 110 can be inserted into the gasket 120 through the notch to achieve a locking engagement with the gasket 120. The gasket 120 can be a metal retaining ring with elastic deformation capability, and its notch is smaller than the outer diameter of the threaded fastener 110, allowing the threaded fastener 110 to be squeezed through its notch and thus locked into the gasket 120.

[0053] When the threaded fastener 110 is a regular bolt, the washer 120 can be press-fitted with the bolt 113 to achieve a lock-lock fit. When the threaded fastener 110 includes a head 111 and a shank 112, the washer 120 is fitted onto the smooth shank 1121. Furthermore, the washer 120 can either be press-fitted with the smooth shank 1121 or left unfitted on the smooth shank 1121 and achieve a lock-lock fit through the threaded section 1122 with a larger outer diameter.

[0054] Furthermore, this application also provides a fastening assembly (not shown in the figure), through which the first part 200 and the second part 300 can also be fixedly connected. The fastening assembly may be a part of the fixed installation structure 100, wherein the fastening assembly includes a threaded fastener 110 and a washer 120.

[0055] The threaded fastener 110 includes a head 111 and a shank 112 extending from one side of the head 111. The shank 112 includes a smooth section 1121 near the head 111 and a threaded section 1122 away from the head 111. The washer 120 has a threaded through hole 121 through which the threaded fastener 110 passes, and the threaded section 1122 can be threadedly engaged with the threaded through hole 121.

[0056] During assembly of product equipment 10, the threaded segment 1122 passes through the mounting through hole 130 and then completely through the threaded through hole 121, finally extending into the threaded mounting hole 140 and screwed into it, thereby fixing the first part 200 and the second part 300. The outer diameter of the threaded segment 1122 is approximately the same as the inner diameter of the threaded through hole 121, allowing for threaded engagement when passing through it. When separating the first part 200 and the second part 300, the threaded fastener 110 is rotated and withdrawn from the threaded mounting hole 140. Because the threaded through hole 121 of the washer 120 engages with the threaded segment 1122 to prevent retraction, the washer 120 effectively limits the threaded fastener 110, ensuring that the disassembled threaded fastener 110 remains on the first part 200.

[0057] The aforementioned fixed mounting structure 100 and product equipment 10, with the threaded fastener 110 passing sequentially through the mounting through hole 130 and the washer 120 and screwed into the threaded mounting hole 140, connect the first part 200 and the second part 300. When it is necessary to separate the first part 200 and the second part 300, simply rotate the threaded fastener 110 to remove it from the threaded mounting hole 140. Because the washer 120 engages with the threaded fastener 110, it acts as a stop, preventing the threaded fastener 110 from exiting the mounting through hole 130. Thus, the disassembled threaded fastener 110 remains on the first part 200, preventing it from rolling off. During reassembly, the threaded fastener 110 can be quickly screwed into the threaded mounting hole 140, thereby improving disassembly and assembly efficiency.

[0058] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above 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.

[0059] The embodiments described above are merely illustrative of several implementation methods of this application, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the patent application. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this application, and these all fall within the protection scope of this application. Therefore, the protection scope of this patent application should be determined by the appended claims.
