The threaded segment can be threadedly engaged with the threaded through hole.

[0005] A fixed mounting structure is used to connect a first part and a second part. The fixed mounting structure includes a threaded fastener, a gasket, a mounting through hole in the first part, and a threaded mounting hole in the second part. The gasket can be clamped between the first part and the second part. The threaded fastener can pass through the mounting through hole and the gasket in sequence and be screwed with the threaded mounting hole to fix the first part to the second part. The gasket and the threaded fastener are in retreat-proof engagement along the extension direction of the threaded fastener.

[0006] In one embodiment, the gasket has a threaded through hole for the threaded fastener to pass through.

[0007] In one embodiment, the threaded fastener includes a head and a rod portion extending from one side of the head. The rod portion includes a smooth rod segment near the head and a threaded segment away from the head. The threaded segment can pass through the mounting through hole and the threaded through hole in sequence and be screwed with the threaded mounting hole, and the smooth rod segment is arranged in the threaded through hole.

[0008] In one embodiment, the outer diameter of the smooth rod segment is smaller than the outer diameter of the threaded segment.

[0028] Please see Figure 1 This utility model 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.

[0029] 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.

[0030] Please refer to the following: Figure 2 In one embodiment of the present invention, the fixed installation structure 100 includes a threaded fastener 110, a washer 120, a mounting through hole 130, and a threaded mounting hole 140.

[0031] The mounting hole 130 is formed on the first part 200, and the threaded mounting hole 140 is formed on the second part 300. The first part 200 and the second part 300 can be mounted by one fixing mounting structure 100, or can be mounted by multiple fixing mounting structures 100. Correspondingly, one or more mounting holes 130 and threaded mounting holes 140 are formed on the first part 200 and the second part 300, respectively.

[0032] The gasket 120 can be clamped between the first part 200 and the second part 300, and the threaded fastener 110 can be sequentially threaded through the mounting hole 130 and the gasket 120 and screwed with the threaded mounting hole 140 to fix the first part 200 to the second part 300. The gasket 120 can be made of metal or plastic, preferably metal, which is wear-resistant and anti-deformation. When assembling the product equipment 10, the threaded fastener 110 can be threaded through the mounting hole 130 first, then the gasket 120 is sleeved on the end of the threaded fastener 110 protruding from the mounting hole 130, and finally the threaded fastener 110 is inserted into the threaded mounting hole 140 and gradually tightened.

[0033] Further, the gasket 120 and the threaded fastener 110 are in retreat-stopping cooperation along the extension direction of the threaded fastener 110. That is, without external force acting on the gasket 120, rotating the threaded fastener 110 cannot make the gasket 120 fall off the threaded fastener 110.

[0034] When the product equipment 10 needs to be overhauled and maintained, the threaded fastener 110 can be rotated and withdrawn from the threaded mounting hole 140 to separate the first part 200 and the second part 300. As shown in Figure 3 Since the gasket 120 and the threaded fastener 110 are in retreat-stopping cooperation, the gasket 120 will still be on the threaded fastener 110 during the process of withdrawing the threaded fastener 110 from the threaded mounting hole 140. In this way, the gasket 120 can limit the threaded fastener 110, thereby preventing the threaded fastener 110 from being withdrawn from the mounting hole 130. That is, the disassembled threaded fastener 110 will still be on the first part 200, so the threaded fastener 110 is not easy to roll off, and when reassembling, 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 efficiency.

[0035] In order to solve the problem that the threaded fastener 110 is easy to roll after being disassembled, the applicant finds that the threaded hole can also be arranged on the first part 200 to cooperate with the threaded fastener 110 to achieve installation. The threaded fastener 110 can be screwed with the threaded hole and the threaded mounting hole 140 on the second part 300 in sequence, so as to fix the first part 200 to the second part 300. Moreover, after rotating the threaded fastener 110 and making it exit from the threaded mounting hole 140, the threaded fastener 110 can still be screwed with the threaded hole of the first part 200 and be left on the first part 200. However, since the first part 200 (such as a cover) is usually formed by a plastic material such as PVC, opening the threaded hole is easy to cause damage to the first part 200, thereby affecting the service life of the product equipment 10.

[0036] Based on the above consideration, in order to solve the problem that the threaded fastener 110 is easy to roll after being disassembled without affecting the service life of the product equipment 10, the applicant designs a fixed mounting structure 100 through in-depth research, which can be left on the first part 200 by increasing the gasket 120 capable of being screwed with the threaded fastener 110. In this way, the first part 200 will not need to open a threaded hole, so as not to adversely affect the service life of the product equipment 10.

[0037] Preferably, in the embodiment, the mounting through hole 130 is arranged as a light hole. That is, the inner wall of the mounting through hole 130 is smooth and does not form an internal thread, so that the threaded fastener 110 will not be screwed with the mounting through hole 130 when passing through the mounting through hole 130.

[0038] The gasket 120 and the threaded fastener 110 can be screwed with each other to achieve the stop-retaining cooperation. Specifically, in the embodiment, the gasket 120 is provided with a threaded through hole 121 for the threaded fastener 110 to pass through, and the threaded fastener 110 can be screwed with the threaded through hole 121 during the process of passing through the threaded through hole 121 to achieve the stop-retaining cooperation with the gasket 120.

[0039] 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 gasket 120 is to be exited from the threaded fastener 110, the gasket 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 cooperation of the internal thread and the external thread can play a stop-retaining role on the gasket 120.

[0040] Please refer to Figure 2 and refer to Figure 4In the embodiment, the threaded fastener 110 includes a head 111 and a shank 112 extending from the head 111, the shank 112 includes a smooth shank section 1121 close to the head 111 and a threaded section 1122 away from the head 111. The threaded section 1122 can pass through the mounting hole 130 and the threaded hole 121 in sequence and be screwed with the threaded mounting hole 140, and the smooth shank section 1121 is arranged in the threaded hole 121.

[0041] The surface of the smooth shank section 1121 is not provided with external threads, and the surface of the threaded section 1122 is provided with external threads. When the product equipment 10 is assembled, the threaded section 1122 passes through the mounting hole 130 and then completely passes through the threaded hole 121, and finally extends into the threaded mounting hole 140 and is screwed with the threaded mounting hole 140. The outer diameter of the threaded section 1122 is equivalent to the inner diameter of the threaded hole 121, and the threaded section 1122 can be screwed with the threaded hole 121 when passing through the threaded hole 121.

[0042] After the threaded fastener 110 is tightened in place, the smooth shank section 1121 is arranged in the threaded hole 121. Since the smooth shank section 1121 is not provided with external threads, there will be no threaded connection between the threaded fastener 110 and the threaded hole 121 after the product equipment 10 is assembled. Therefore, when the threaded fastener 110 is removed, rotating the threaded fastener 110 will not drive the gasket 120 to rotate along the threaded fastener 110, thereby better preventing the gasket 120 from being removed.

[0043] Further, in the embodiment, the outer diameter of the smooth shank section 1121 is smaller than the outer diameter of the threaded section 1122. Since the outer diameter of the threaded section 1122 is equivalent to the inner diameter of the threaded hole 121, the outer diameter of the smooth shank section 1121 is also smaller than the inner diameter of the threaded section 1122. Therefore, the gasket 120 can be loosely arranged on the smooth shank section 1121, so that the gasket 120 will not rotate when the threaded fastener 110 is rotated, and the gasket 120 is better prevented from being removed.

[0044] More specifically, in the embodiment, the gasket 120 is in the shape of a ring, and the threaded hole 121 is coaxially arranged with the gasket 120. Therefore, after the threaded fastener 110 passes through the threaded hole 121, the gasket 120 and the threaded fastener 110 will also be coaxially arranged, so that the gasket 120 better limits the threaded fastener 110.

[0045] Please refer to Figure 5 In another embodiment, the threaded fastener 110 can also adopt a common bolt structure. Specifically, the threaded fastener 110 includes a head 111 and a screw rod 113 extending from the head 111, the screw rod 113 can pass through the mounting hole 130 and the threaded hole 121 in sequence and be screwed with the threaded hole 121 and the threaded mounting hole 140.

[0046] When the threaded fastener 110 is disassembled, the washer 120 will not rotate with the threaded fastener 110 at the initial stage due to the clamping of the first part 200 and the second part 300, so that the washer 120 is angularly displaced relative to the rotating threaded fastener 110 and retracts a certain distance relative to the threaded fastener 110. With the continuous rotation of the threaded fastener 110, once the first part 200 and the second part 300 are loosened, the washer 120 will rotate synchronously with the threaded fastener 110 due to the loss of the clamping of the first part 200 and the second part 300. At this time, the washer 120 does not have angular displacement relative to the threaded fastener 110, so it will not continue to retract relative to the threaded fastener 110, thereby achieving the purpose of retraction.

[0047] In addition, the washer 120 can also be connected with the threaded fastener 110 in other ways. For example, in an embodiment, the washer 120 can be provided in the form of a ring with a notch (not shown), and the threaded fastener 110 can be clamped into the washer 120 through the notch to achieve the retraction with the washer 120. The washer 120 can be a metal snap ring with elastic deformation capability, and the notch is smaller than the outer diameter of the threaded fastener 110, so that the threaded fastener 110 can be squeezed through the notch to be clamped into the washer 120.

[0048] For the case that the threaded fastener 110 is a common bolt, the washer 120 can be in interference fit with the threaded rod 113 to achieve the retraction. For the case that the threaded fastener 110 includes the head 111 and the rod 112, the washer 120 is sleeved on the smooth rod segment 1121. Moreover, the washer 120 can be in interference fit with the smooth rod segment 1121, or can be in empty sleeve on the smooth rod segment 1121 and achieve the retraction through the threaded segment 1122 with a larger outer diameter.

[0049] In addition, the utility model also provides a fastening assembly (not shown), and the first part 200 and the second part 300 can also be fixedly connected through the above-mentioned fastening assembly. The above-mentioned fastening assembly can be part of the above-mentioned fixed mounting structure 100, wherein the above-mentioned fastening assembly includes the threaded fastener 110 and the washer 120.

[0050] The threaded fastener 110 includes the head 111 and the rod 112 extending from one side of the head 111, and the rod 112 includes the smooth rod segment 1121 close to the head 111 and the threaded segment 1122 away from the head 111. The washer 120 is provided with a threaded through hole 121 for the threaded fastener 110 to pass through, and the threaded segment 1122 can be in threaded fit with the threaded through hole 121.

[0051] When the product equipment 10 is assembled, the threaded section 1122 passes through the mounting hole 130, then passes through the threaded hole 121 completely, and finally extends into the threaded mounting hole 140 and is screwed with the threaded mounting hole 140, thereby fixing the first part 200 and the second part 300. The outer diameter of the threaded section 1122 is equivalent to the inner diameter of the threaded hole 121, and the threaded section 1122 can be screwed with the threaded hole 121 when passing through the threaded hole 121. When the first part 200 and the second part 300 are separated, the threaded fastener 110 is rotated and withdrawn from the threaded mounting hole 140. Since the threaded hole 121 of the gasket 120 can be screwed with the threaded section 1122 to achieve retreat prevention, the gasket 120 can limit the threaded fastener 110, so that the disassembled threaded fastener 110 can be placed on the first part 200.

[0052] The fixed mounting structure 100 and the product equipment 10 described above, the threaded fastener 110 passes through the mounting hole 130 and the gasket 120 in sequence and is screwed with the threaded mounting hole 140, thereby connecting the first part 200 and the second part 300. When the first part 200 and the second part 300 need to be separated, the threaded fastener 110 is rotated and withdrawn from the threaded mounting hole 140. Since the gasket 120 is in retreat prevention with the threaded fastener 110, the gasket 120 can limit the threaded fastener 110, thereby preventing the threaded fastener 110 from being withdrawn from the mounting hole 130. In this way, the disassembled threaded fastener 110 will still be placed on the first part 200, so that the threaded fastener 110 is not easy to roll off, and when reassembled, the threaded fastener 110 can be quickly screwed into the threaded mounting hole 140, thereby improving the disassembly and assembly efficiency.

[0053] The technical features of the above-described embodiments can be combined in any manner. To make the description concise, all possible combinations of the technical features in the above-described embodiments are not described, but as long as the combinations of the technical features do not contradict, they should be considered within the scope of the present disclosure.

[0054] The above-described embodiments only express several implementation manners of the present application, and the description is relatively specific and detailed, but it should not be understood as a limitation on the scope of the present application. It should be noted that for ordinary skilled persons in the art, without departing from the concept of the present application, a number of modifications and improvements can be made, which are within the protection scope of the present application.
