Description

Technical Field

[0001] This utility model relates to the field of automotive interior technology, and in particular to a passenger bus floor inspection cover. Background Technology

[0002] Bus floor inspection covers are an indispensable structure for inspecting components under the vehicle floor. They mainly serve to decorate the interior environment and protect the components under the floor.

[0003] In existing technologies, conventional small-diameter bus floor access covers are typically installed using screws. However, due to unavoidable assembly errors during the assembly of bus floor panels, on-site work is often required to install the access covers, involving drilling holes before securing the screws. This installation method presents several problems: First, the process is cumbersome, requiring additional drilling steps, consuming significant time, and reducing overall assembly efficiency; second, the use of screws can result in missing screws on the access cover surface, severely affecting the aesthetics of the bus interior; third, on-site drilling generates debris that can easily scratch the floor covering, affecting its lifespan and requiring additional cleaning, further increasing the labor intensity and operating costs for workers. Utility Model Content

[0004] Other features and advantages of this invention will be set forth in the description which follows, and will be apparent in part from the description, or may be learned by practicing the invention. The objects and other advantages of this invention may be realized and obtained by means of the structures particularly pointed out in the description and other accompanying drawings.

[0005] The purpose of this utility model is to overcome the above-mentioned shortcomings and provide a bus floor inspection cover.

[0006] To achieve the above objectives, the technical solution of this utility model is: a bus floor inspection cover, comprising: a sealing plate, a fixing ring, an outer cover, and an inner cover. The fixing ring is provided with a buckle for engaging with the sealing plate. The lower side of the outer cover is provided with an external thread. The inner ring of the fixing ring is provided with an internal thread that engages with the external thread. The inner cover covers the outer cover.

[0007] In some embodiments, the inner cover has a tool operating groove.

[0008] In some embodiments, a boss is provided around the inner cover.

[0009] In some embodiments, the inner wall of the outer cover has a notch for the boss to enter.

[0010] In some embodiments, an inner snap-fit ​​is installed on the inner wall of the outer cover.

[0011] In some embodiments, the inner snap-fit ​​is connected to the side of the notch and is used to engage and fix the boss with the inner snap-fit ​​after the boss enters the notch and rotates.

[0012] In some embodiments, the rotation direction of the inner cover is opposite to the rotation direction of the outer cover when it is screwed into the retaining ring.

[0013] By adopting the above technical solution, the beneficial effects of this utility model are as follows: This utility model eliminates the need for on-site drilling during the installation of the inspection cover, using threaded rotation for fixation, thus avoiding drilling and screw tightening, improving efficiency, simplifying the installation process, significantly shortening installation time, and increasing assembly efficiency. Simultaneously, the inspection cover surface is free of missing nails, effectively enhancing the aesthetics of the bus interior. Furthermore, the inner cover is easy to disassemble and can be reused repeatedly for a long time, reducing usage costs. In addition, its wide applicability further enhances the practicality and market competitiveness of this inspection cover.

[0022] The following detailed description of the embodiments of this utility model, in conjunction with the accompanying drawings, will provide a thorough understanding of how this utility model uses technical means to solve technical problems and achieve technical effects, enabling its implementation. It should be noted that, provided there is no conflict, the various embodiments and features within them can be combined with each other, and all resulting technical solutions are within the protection scope of this utility model.

[0023] Furthermore, numerous specific details are set forth in the following description for illustrative purposes to provide a thorough understanding of the embodiments of this invention. However, it will be apparent to those skilled in the art that this invention may be practiced without the specific details or particular methods described herein.

[0024] Please see Figure 1-5 This utility model provides a bus floor inspection cover, including: a sealing plate 1, a fixing ring 2, an outer cover 3, and an inner cover 4. The fixing ring 2 is provided with a buckle 5 for engaging with the sealing plate 1. The lower side of the outer cover 3 is provided with an external thread 6. The inner ring of the fixing ring 2 is provided with an internal thread 7 that engages with the external thread 6. The inner cover 4 covers the outer cover 3.

[0025] Before the inspection cover is installed, the bus floor has an inspection hole pre-drilled. The floor can usually be separated into a wooden board and a sealing plate 1. The sealing plate 1 with a clip or groove is placed into the inspection hole, and then the fixing ring 2 is placed on the inspection hole so that the buckle 5 of the fixing ring 2 is engaged with the edge of the sealing plate 1, thus achieving the pre-fixation of the fixing ring 2. Next, the outer cover 3 is aligned with the fixing ring 2. Through the cooperation of the internal thread 7 and the external thread 6, the outer cover 3 can be gradually screwed into the fixing ring 2 until the outer cover 3 and the fixing ring 2 cooperate to clamp and fix the wooden board. Finally, the inner cover 4 is placed on the outer cover 3.

[0026] According to some embodiments of this application, optionally, a tool operating groove 8 is provided on the inner cover 4. Workers can use tools to insert into the tool operating groove 8 and rotate or pull it open.

[0027] According to some embodiments of this application, optionally, a boss 9 is installed around the inner cover 4, and a notch 10 is opened on the inner wall of the outer cover 3 for the boss 9 to enter. The boss 9 and the notch 10 cooperate to position and guide the inner cover 4 when it is closed onto the outer cover 3, so that it is placed along the notch 10 and prevents it from shaking easily.

[0028] According to some embodiments of this application, optionally, an inner snap-fit ​​11 is installed on the inner wall of the outer cover 3. The inner snap-fit ​​11 is connected to the side of the notch 10 and is used to engage and fix the boss 9 with the inner snap-fit ​​11 after the boss 9 enters the notch 10 and rotates. The inner cover 4 is placed on the outer cover 3, so that the boss 9 of the inner cover 4 enters the notch 10 of the outer cover 3. Then, the inner cover 4 is rotated until the boss 9 is fixedly engaged and fixed with the inner snap-fit ​​11 of the outer cover 3, thus completing the installation of the entire inspection cover. When it is necessary to inspect the components under the bus floor, the staff uses a tool to insert into the tool operating groove 8 of the inner cover 4, rotates the inner cover 4, and separates the boss 9 of the inner cover 4 from the inner snap-fit ​​11 of the outer cover 3, so that the inner cover 4 can be removed and the components under the floor can be inspected. After the inspection is completed, the installation steps are reversed to reinstall the inner cover 4. The entire disassembly process is simple to operate, does not require complicated tools, and will not damage the inspection cover and the wooden floor, allowing for long-term reuse of the inspection cover.

[0029] According to some embodiments of this application, optionally, the rotation direction of the inner cover 1 is opposite to the rotation direction of the outer cover 2 when it is screwed into the fixing ring 3. The reverse rotation fixing design can effectively prevent the inner cover 1 from loosening due to vibration during bus operation, ensuring the stability of the inner cover 1, and also facilitating the disassembly of the inner cover 1 during subsequent maintenance.

[0030] According to some embodiments of this application, optionally, the bus floor inspection cover is not only applicable to the inspection of the bus floor, but can also be applied to the inspection locations of components such as the front and rear panels and air ducts inside the vehicle, thus expanding the scope of application of the inspection cover and increasing its value.
