[0033] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings.

[0034] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Those skilled in the art can make similar extensions without departing from the spirit of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0035] Secondly, the term "an embodiment" or "embodiment" as used herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The phrase "in one embodiment" appearing in different places in this specification does not necessarily refer to the same embodiment, nor is it a single or selective embodiment that excludes other embodiments.

[0036] Example 1: Refer to Figures 1-5This is the first embodiment of the present utility model. This embodiment provides a bolt and nut sealing cover assembly, which can achieve the same results as most bolt and nut sealing cover assemblies currently on the market. When fixing and installing the engine sealing cover assembly, the operator needs to use a wrench to clamp the nut to install it with the bolt. This installation method is inconvenient for the operator and increases the labor intensity of the operator. It includes a generator mechanism 1, which includes a first mounting plate 101. The first mounting plate 101 is fixedly installed at one end of the generator mechanism 1. A second mounting plate 102 is provided at the end of the first mounting plate 101 away from the generator mechanism 1. A filter screen frame 103 is installed inside the second mounting plate 102. A bolt body 104 is rotatably installed inside the second mounting plate 102 through a bearing. The first mounting plate 101 has a first through hole 1011. A disc body 105 is installed at one end of the bolt body 104. The disc body 105 and the bolt body 104 are welded as an integral structure. A rubber sleeve is installed on the outer wall of the disc body 105 to protect the operator's hands when rotating the disc body 105.

[0037] The positioning and fixing mechanism 2 includes a fixed round rod 201, which is fixedly installed on the side wall of one end of the first mounting plate 101. A nut collar 203 is sleeved on the outer wall of the fixed round rod 201, and a nut sleeve 202 is installed at one end of the nut collar 203. A rubber ring 205 is sleeved on the outer wall of the fixed round rod 201.

[0038] The nut collar 203 has a second through hole 204 inside, and the second through hole 204 cooperates with the fixed round rod 201. The inner walls of the nut sleeve 202 and the nut collar 203 are both provided with threaded teeth 2031, and the threaded teeth 2031 are threadedly connected to the bolt body 104. Through the threaded connection between the threaded teeth 2031 and the bolt body 104, the bolt body 104 is rotated, thereby driving the nut collar 203 and the nut sleeve 202 to slide on the outer wall of the bolt body 104.

[0039] Each rubber ring 205 has a third through hole 206 inside, and the third through hole 206 cooperates with the fixed round rod 201. Through the cooperation between the third through hole 206 and the fixed round rod 201, the bolt body 104 is rotated, thereby causing the rubber ring 205 to slide on the outer wall of the bolt body 104.

[0040] The specific working principle is as follows: when it is necessary to position and fix the first mounting plate 101 and the second mounting plate 102, the bolt body 104 is first rotated by rotating the disc body 105. The bolt body 104 is threadedly connected to the threaded teeth 2031 and cooperates with the fixed round rod 201 through the second through hole 204. Furthermore, it cooperates with the fixed round rod 201 through the third through hole 206. The rotation of the bolt body 104 causes the nut sleeve 202 and the nut collar 203 to slide on the outer wall of the bolt body 104 through the fixed round rod 201. This facilitates the sliding of the nut sleeve 202 and the nut collar 203, which in turn compresses the rubber ring 205. Thus, the second mounting plate 102 and the first mounting plate 101 are fixedly installed by the sliding of the nut collar 203 and the rubber ring 205, making it easier for the operator to operate.

[0041] Example 2: Refer to Figures 1-5 This is the first embodiment of the present invention. This embodiment provides a bolt and nut sealing cover assembly, which can solve the problem that most bolt and nut sealing cover assemblies on the market require operators to use a wrench to clamp the nut and install it with the bolt when fixing and installing the engine sealing cover assembly.

The nut sleeve 202 includes a first stainless steel layer 2021, a reinforcing layer 2022 is provided at the bottom end of the first stainless steel layer 2021, a copper alloy layer 2023 is provided at the bottom end of the reinforcing layer 2022, a titanium alloy layer 2024 is provided at the bottom end of the copper alloy layer 2023, and a second stainless steel layer 2025 is provided at the bottom end of the titanium alloy layer 2024. Through the design of the copper alloy layer 2023 and the titanium alloy layer 2024, the service life of the nut sleeve 202 is extended.

[0042] The top of the inner core 2022 is equipped with an upper reinforcing rib 20221 arranged horizontally, and the bottom of the inner core 2022 is equipped with a lower reinforcing rib 20222 arranged horizontally. The lower reinforcing rib 20222 and the upper reinforcing rib 20221 cooperate with each other. Through the cooperation of the lower reinforcing rib 20222 and the upper reinforcing rib 20221, the nut sleeve 202 is more secure.

[0043] The specific working principle is as follows: First, the bottom and top of the reinforcing layer 2022 are horizontally arranged with lower reinforcing ribs 20222 and upper reinforcing ribs 20221, which improve the firmness of the nut sleeve 202. At the same time, the design of the copper alloy layer 2023 and the titanium alloy layer 2024 extends the service life of the nut sleeve 202.

[0044] The above description of the disclosed embodiments enables those skilled in the art to make or use the present invention.
