Description

Technical Field

[0001] This utility model relates to the technical field of auxiliary equipment on fire trucks, specifically a flip-up pedal structure. Background Technology

[0002] Fire trucks often have storage compartments above the wheels to increase their carrying capacity because they need to carry a large amount of fire-fighting equipment. However, this location is usually quite far from the ground, and operators face the following technical problems when retrieving and placing equipment.

[0003] First, when there is no dedicated step under the storage box on the fire truck, the standing platform is missing. As a result, personnel have to climb the vehicle or use temporary tools, which poses a risk of slipping and is inefficient. If a fixed step is installed, it will encroach on the tire movement space, affect the vehicle's steering or passability, and create a spatial interference hazard. Therefore, a flip-up step structure is proposed. Utility Model Content

[0004] Based on the above description, this utility model provides a flip-up pedal structure, which solves the technical problems pointed out in the background art.

[0005] The technical solution of this utility model to solve the above-mentioned technical problems is as follows: A flip-up pedal structure for use on fire trucks includes a mounting plate, a flip-up frame, a gas spring, a panel, and a lever-type flat lock. There are two sets of mounting plates. The flip-up frame is flipped and arranged between the two sets of mounting plates. There are two gas springs, which are hinged between the flip-up frame and the two sets of mounting plates. The panel is fixed to the front side of the flip-up frame.

[0009] Furthermore, the flipping frame also includes two sets of reinforcing square tubes, which are inclined at a 45-degree angle and fixed between the bottom of the connecting square tube and the side walls of the front and rear square tubes.

[0010] Furthermore, a second reinforcing square tube is fixed between the two first reinforcing square tubes.

[0011] Furthermore, a reinforcing square tube three is fixed between the two sets of reinforcing square tube one and the adjacent front or rear square tube. A notch is provided on the outer side of the reinforcing square tube three to provide space for the rotation of the gas spring two.

[0025] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0026] Since fire trucks need to accommodate a large number of firefighting equipment, storage compartments are usually designed above the wheels to accommodate more equipment. Therefore, it is necessary to study how to make it easy for operators to access the firefighting equipment in these storage compartments. For this purpose, a flip-up pedal structure was designed.

[0027] like Figure 1-7 As shown, this embodiment presents a flip-up pedal structure for use on a fire truck, comprising mounting plates 1. There are two sets of mounting plates 1, spaced apart and symmetrically distributed. Both sets of mounting plates 1 are provided with bolt holes. When bolts are driven into the bolt holes and connected to the fire truck frame through the bolts, the flip-up pedal structure can be installed. The mounting plates 1 are L-shaped and consist of an integrally connected long plate and a short plate. The bolt holes are opened on the long plate. A flip-up frame 2 can be flipped between the two sets of mounting plates 1. Specifically, the flip-up pedal structure also includes two gas springs 3, which are hinged between the flip-up frame 2 and the two sets of mounting plates 1.

[0028] Under normal conditions, gas spring 3 generates thrust by expanding gas to restore its original shape when stretched, thus providing support and assistance, and the flip frame 2 maintains its stability at this time. When the flip frame 2 is flipped 90 degrees, gas spring 3 generates elastic force by compressing the internal gas when compressed, thus forming a limiting support for the flip frame 2.

[0029] Further explanation: To provide a standing platform and to avoid interference with the tires, Figure 1 Taking the perspective as an example, a panel 4 is fixed on the front side of the flip frame 2. An installation port is opened through the front side of the panel 4, and a lever-type flat lock 5 is installed at the installation port. The preferred model is MS718-3, which is existing technology and will not be described in detail here. On the side of the flip frame 2 away from the panel 4, a baffle 6 is rotatably connected by a pivot. The baffle 6 is connected to the lever of the lever-type flat lock 5. Furthermore, it should be noted that a gas spring 7 is hinged between the flip frame 2 and the baffle 6, so that the flip angle of the baffle 6 is ninety degrees.

[0030] It should be noted that, to ensure stability, there are two sets of lever-type planar locks 5, which are symmetrically distributed.

[0031] Under normal circumstances, such as Figure 1 As shown, the baffle 6 is in the unfolded state, thus not interfering with the tires. The gas spring 7, in its stretched state, generates thrust by expanding the gas to return to its original shape, providing support for the baffle 6. When a person needs to stand on the baffle 6, after the flip frame 2 flips ninety degrees, the flipping pedal structure... Figure 2 As shown, the subsequent flip-up baffle 6 is 90 degrees, and the flip-up pedal structure is as follows. Figure 3 As shown, when the gas spring 7 is compressed, it generates elastic force through the compression of internal gas, which forms a limiting support for the baffle. In this way, the baffle 6 can provide a standing space for personnel, making it convenient for personnel to access fire-fighting equipment. In addition, when it is necessary to press the button of the lever-type flat lock 5, the baffle 6 can be flipped open. Of course, it is understandable that the outer side of the baffle 6 can also have anti-slip texture for anti-slip purposes.

[0032] In the preferred embodiment, the flip frame 2 includes a square tube component 21, which includes a front tube, a rear tube, and a connecting square tube. The square tube component 21 is U-shaped, and a groove is provided on the outer side of the connecting square tube to facilitate the flipping of the lever of the lever-type flat lock 5 and limit its maximum flipping angle. The flip frame 2 also includes two sets of reinforcing square tubes 1 22. The reinforcing square tubes 1 22 are inclined, for example, at a 45-degree angle, and fixed between the bottom of the connecting square tube and the side walls of the front and rear tubes. To further enhance the structural strength, a reinforcing square tube 23 is fixed between the two reinforcing square tubes 1 22, and a reinforcing square tube 3 24 is fixed between the two sets of reinforcing square tubes 1 22 and the adjacent front or rear tube. It should be noted that a notch is provided on the outer side of the reinforcing square tube 3 24 to provide space for the rotation of the gas spring 2 7.

[0033] In addition, an upper sealing strip 8 is fitted on the top of panel 4, and panel 4 has a hollow area, on which a double bubble sealing strip 9 is fitted on the side wall of the hollow area of ​​panel 4.

[0034] In the above design, the device has a simple structure and a smooth flipping mechanism. When the baffle 6 and the flipping frame 2 are unfolded and retracted, the operation is convenient and quick. The designed gas spring 1 3 and gas spring 2 7 can provide good support, and have reliability and safety. In addition, the designed flipping frame 2 and baffle 6 allow personnel to stand on the baffle 6 to retrieve fire-fighting equipment, providing convenient operation.

[0035] The above are merely preferred embodiments of this utility model, but the scope of protection of this utility model is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in this utility model, based on the technical solution and inventive concept of this utility model, should be included within the scope of protection of this utility model.
