Description

Technical Field

[0001] This utility model belongs to the field of aircraft wheel stop technology, specifically a new type of aircraft wheel stop. Background Technology

[0002] Aircraft wheel chocks are the most commonly used ground support equipment for most aircraft that rely primarily on tire rotation for ground movement. Their function is to prevent unplanned displacement of the aircraft when it is parked.

[0003] However, when managing existing aircraft wheel chocks in accordance with the SAE AI R 4905A-2021 standard, the weight of the rubber wheel chocks has far exceeded the load limit of the service personnel, and they are inconvenient to pick up and put down.

[0004] To address the problems raised in the background art, those skilled in the art have proposed a novel aircraft wheel stop. Utility Model Content

[0005] To address the aforementioned technical problems, this utility model provides a novel aircraft wheel stop to solve the problems in the prior art.

[0006] A novel aircraft wheel stop includes a body, the bottom of which has a plurality of recessed cavities evenly distributed, the top of which has a plurality of through holes vertically downward, and one side of which has a plurality of receiving holes horizontally distributed.

[0007] Preferably, the body is composed of an upper isosceles trapezoid and a lower rectangle, and the body is integrally made of polyurethane dyeing material.

[0008] Preferably, the recessed cavity includes a first recessed cavity, a second recessed cavity, a third recessed cavity, and a fourth recessed cavity.

[0009] Preferably, the through hole includes a first through hole, a second through hole, a third through hole, and a fourth through hole.

[0010] Preferably, the receiving hole includes a first receiving hole, a second receiving hole, and a third receiving hole.

[0011] Preferably, the first through hole, the second through hole, the third through hole, and the fourth through hole are respectively connected to the first recessed cavity, the second recessed cavity, the third recessed cavity, and the fourth recessed cavity.

[0012] Preferably, the first receiving hole, the second receiving hole, and the third receiving hole are all in communication with the fourth recessed cavity.

[0013] Compared with the prior art, the present invention has the following beneficial effects:

[0014] 1. This utility model uses the inclined surface of the isosceles trapezoid of the main body to make contact with the aircraft wheel, thereby enabling the main body 1 to limit the aircraft after it stops, making its parking state safer and more reliable, and avoiding unplanned displacement of the aircraft.

[0015] 2. This utility model achieves the placement and removal of the device by using two ropes in conjunction with the recessed cavity, through hole and receiving hole.

[0016] 3. This utility model uses polyurethane dyeing material and has an optimized overall structure design, which reduces the weight of the wheel chock body while meeting the specifications, significantly reducing the burden on service personnel and making it easier to identify in various usage scenarios.

Detailed Implementation

[0020] The embodiments of this utility model will be described in further detail below with reference to the accompanying drawings and examples. The following examples are for illustrative purposes only and should not be construed as limiting the scope of this utility model.

[0021] like Figures 1 to 2 As shown:

[0022] Example 1: This utility model provides a novel aircraft wheel stop, including a body 1, a plurality of recessed cavities 2 evenly opened at the bottom of the body 1, a plurality of through holes 3 vertically downward opened at the top of the body 1, and a plurality of receiving holes 4 horizontally opened on one side of the body 1.

[0023] Furthermore, the main body 1 is composed of an upper isosceles trapezoid and a lower rectangle. The main body 1 is integrally made of polyurethane dyeing material, which makes the wheel obstruction visible and easily identifiable day and night.

[0024] Furthermore, the recessed cavity 2 includes a first recessed cavity 21, a second recessed cavity 22, a third recessed cavity 23, and a fourth recessed cavity 24.

[0025] Furthermore, the through hole 3 includes a first through hole 31, a second through hole 32, a third through hole 33, and a fourth through hole 34.

[0026] Furthermore, the receiving hole 4 includes a first receiving hole 41, a second receiving hole 42, and a third receiving hole 43.

[0027] Furthermore, the first through hole 31, the second through hole 32, the third through hole 33 and the fourth through hole 34 are respectively connected to the first recessed cavity 21, the second recessed cavity 22, the third recessed cavity 23 and the fourth recessed cavity 24.

[0028] Furthermore, the first receiving hole 41, the second receiving hole 42 and the third receiving hole 43 are all connected to the fourth recessed cavity 24.

[0029] As can be seen from the above, by making contact between the inclined surface of the isosceles trapezoid of the main body 1 and the aircraft wheel, the main body 1 can limit the aircraft after it stops, making its parking state safer and more reliable, and avoiding unplanned displacement of the aircraft.

[0030] It should be noted that: the main body 1 is provided with two ropes, a first rope and a second rope. One end of the first rope is located in the first recessed cavity 21 and is tied in a knot. The other end of the first rope passes through the first through hole 31 and then through the fourth through hole 34, extending into the fourth recessed cavity 24 and passing through the second receiving hole 42. The end of the first rope that passes through is tied in a knot.

[0031] One end of the second rope is located in the fourth recessed cavity 24 and is knotted. The other end of the second rope passes through the first receiving hole 41, passes through the third receiving hole 43, enters the fourth recessed cavity 24, and is knotted.

[0032] Furthermore, when it is necessary to move the main body 1, pulling the first rope can lift the main body 1 upwards, thereby moving the main body 1. Pulling the second rope can move the main body 1 to one side, thereby dragging the main body 1.

[0033] The above operations are used to place and remove this device.

[0034] The embodiments of this utility model are given for the purpose of illustration and description. Although embodiments of this utility model have been shown and described above, it is understood that the above embodiments are exemplary and should not be construed as limiting the utility model. Those skilled in the art can make changes, modifications, substitutions and variations to the above embodiments within the scope of this utility model.
