Description

Technical Field

[0001] The present application relates to the technical field of bridge plates, and more specifically, to a new type of bridge plate. Background Art

[0002] When transporting cargo into the aircraft cabin or a dining cart entering the cabin, a bridge plate is required to overlap the lift platform and the cabin door due to the certain distance between the lift platform and the cabin door to facilitate the movement of the transport vehicle or dining cart.

[0003] The existing bridge plates have no protection at both ends, which does not provide adequate protection for the lower edge of the cabin door. The overlaps at both ends are prone to scratching or indenting the cabin door and other parts. If cushioning pads are used for protection, the risk of foreign objects will increase. In addition, the existing bridge plates are mostly welded at the bends, which are prone to cracking after long-term use and have poor load-bearing capacity. Some of them are fastened by rivets or screws and nuts, which are prone to loosening and falling off. Utility Model Content

[0004] In order to solve the above problems, the present application provides a new type of bridge plate.

[0005] The new type of bridge plate provided in this application adopts the following technical solution:

[0006] A new type of bridge board includes a main board body, the left and right sides of the main board body are bent upward to form side support boards, one end of the main board body is bent downward to form a lap joint, and the bottoms and sides of both ends of the main board body are fixedly connected with flexible protective layers.

[0007] Furthermore, the flexible protective layer includes a first sheath plate and a second sheath plate, and the first sheath plate and the second sheath plate are respectively sleeved and fixedly connected to the outer bottom surface and the side walls at both ends of the main board body.

[0008] Furthermore, both sides of the first sheath plate and the second sheath plate are bent inward to form a clamping groove that is engaged with the side support plate.

[0009] Through the above technical solution, the first sheath plate and the second sheath plate wrap the outer edges of both ends of the main board body, which effectively protects the lower edge of the cabin door, and also makes the connection between the first sheath plate and the second sheath plate and the main board body more stable.

[0010] Furthermore, the length of the first sheath plate is 1 / 4 of the total length of the main plate body, and the length of the second sheath plate is twice the length of the overlapping portion.

[0011] Furthermore, the outer side surfaces of the second sheath plate are sprayed with a marking layer.

[0012] Through the above technical solution, the identification layer can use inkjet technology to spray yellow and black blocks at intervals, which can serve as a warning. At the same time, it can also be used as a scale mark in actual use, thereby improving practicality.

[0013] Furthermore, the total length of the main board body is 1400-1500 mm, the width is 500-550 mm, and the length of the overlapped portion is 1 / 5 of the total length of the main board body.

[0014] Furthermore, the bending angle of the overlapping portion is 10 to 15°.

[0015] Through the above technical solution, it can fit more closely to the overlap of the outer edge of the cabin door, making the placement more stable and having a better anti-slip effect.

[0016] Furthermore, an array of anti-slip grooves is provided on the inner surface of the main board body.

[0035] Embodiment 1:

[0036] The present application is further described in detail below in conjunction with the accompanying drawings.

[0037] The embodiment of the present application discloses a new type of bridge board, including a main board body 1. The main board body 1 is made of 5mm anti-slip aluminum plate. The left and right sides of the main board body 1 are bent upward by an integrated bending process to form side support plates 11, which can significantly enhance the load-bearing capacity. One end of the main board body 1 is bent downward to form a lap joint 12. The bottom and sides of both ends of the main board body 1 are fixedly connected with a flexible protective layer.

[0038] See also Figure 1 , Figure 2 and Figure 4 The flexible protective layer includes a first sheath plate 21 and a second sheath plate 22, which are respectively sleeved and fixedly connected to the outer bottom surface and the side wall at both ends of the main board body 1. The first sheath plate 21 and the second sheath plate 22 are preferably made of rubber. Both sides of the first sheath plate 21 and the second sheath plate 22 are bent inward to form a snap-in groove that is engaged with the side support plate 11. The first sheath plate 21 and the second sheath plate 22 are wrapped with the outer edges of both ends of the main board body 1 using a hot glue coating process to ensure that the glue surface is not easy to fall off, improve durability, and can effectively protect the lower edge of the cabin door to prevent the overlap from scratching the cabin door and other facilities. At the same time, it also makes the connection between the first sheath plate 21 and the second sheath plate 22 and the main board body 1 more stable.

[0039] See also Figure 1-4 The outer side surface of the second sheath plate 22 is sprayed with a marking layer 3, and the marking layer 3 uses inkjet technology to spray yellow and black blocks at intervals, which can serve as a warning and can also be used as a scale mark in actual use.

[0040] As a further preferred embodiment of the present invention, the total length of the main board body 1 is 1420 mm, and the width is 530 mm, wherein the length of the overlap portion 12 is 1 / 5 of the total length of the main board body 1. The length of the first sheath plate 21 is 1 / 4 of the total length of the main board body 1, and the length of the second sheath plate 22 is twice the length of the overlap portion 12. According to actual measurements, this size can be applied to various sizes of models, and is light and easy to use, and convenient to place and store.

[0041] See also Figure 1 or Figure 3 The bending angle of the overlapping portion 12 is 12°. The bending angle of the overlapping portion 12 and the height from the outer edge of the cabin door have been measured on-site for large and small aircraft models. It can fit more closely to the overlapping portion of the outer edge of the cabin door, making the placement more stable and the anti-slip effect better, and the dining cart can be pushed in and out of the cabin more smoothly.

[0042] As a further preference of this embodiment, the inner surface array of the main board body 1 is provided with anti-slip grooves, which can further improve the anti-slip effect of the main board body surface.

[0043] Embodiment 2:

[0044] The difference between this embodiment and embodiment 1 is that Figure 5 As shown, a plurality of through holes are arranged in an array on the main board body 1. The shape of the through holes can be square, circular, strip or special-shaped holes, which can improve the surface friction and prevent the accumulation of dirty liquids (such as rainwater, spilled beverages, etc.) on the surface, thereby achieving an anti-slip effect.

[0045] The implementation principle of a new type of bridge plate in the embodiment of the present application is:

[0046] The present application provides an overlapping portion 12 by bending on one side of the main board body 1, which can fit closely to the outer edge of the cabin door, be stably placed, and make the dining cart enter and exit the cabin more smoothly and steadily; the first sheath plate 21 and the second sheath plate 22 provided on both ends of the main board body 1 can provide better protection for the overlapping portions at both ends, and at the same time further improve the anti-slip effect; the main board body 1 is integrally bent, without welding and rivets, and the components are highly integrated and not easy to fall off. It is light and easy to use, compatible with a variety of models, and more practical. The anti-slip effect of the surface of the main board body 1 is improved by providing anti-slip patterns or anti-slip through holes on the surface, and the identification layer 3 can serve as a warning. At the same time, it can also be used as a scale mark in actual use, further improving its practicality.

[0047] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
