Description

Technical Field

[0001] This utility model relates to the field of reversing pole technology, and in particular to a novel reversing pole structure for special vehicle driving training. Background Technology

[0002] Reversing pole training, also known as parking test or reverse parking, is an important part of the driving license test subject two. It mainly tests the driver's spatial perception and precise control ability of the vehicle while it is in motion. Special vehicles have external dimensions and weight that exceed the design limits of vehicles, so the reversing pole is very easy to be damaged during driving training and is not easy to repair after damage, resulting in high training costs. At present, most of the reversing poles used in the market are iron reversing poles, and the connection between the pole and the base is welded. The base is usually a rectangular base with a thickness of about 8cm and a length and width of 20cm.

[0003] Existing reversing pole bases are generally placed directly on the ground. When the pole shifts or needs to be moved, the instructor usually has to bend over and lift it to a suitable position. However, because the base is heavy, frequent bending over can cause lower back pain. In addition, existing reversing poles are generally inserted directly into the base. When subjected to external force, the reversing pole may pop out of the base and be crushed by the wheel. Therefore, a new reversing pole structure for special vehicle driving training is needed. Utility Model Content

[0004] The purpose of this utility model is to provide a novel reversing pole structure for special vehicle driving training, so as to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a novel reversing pole structure for special vehicle driving training, comprising a malleable iron base, a rotating wheel rotatably mounted inside the malleable iron base, a groove formed on the malleable iron base, an mounting block fixedly mounted on the top of the malleable iron base, a disassembly and assembly mechanism provided inside the mounting block, a first reversing pole slidably mounted inside the mounting block, a connecting pipe fixedly mounted on the top of the first reversing pole, and a second reversing pole snapped into the connecting pipe.

[0006] Preferably, a slide bar is fixedly installed on the first reversing lever, and an installation groove is provided in the mounting block, and the slide bar is slidably installed in the installation groove.

[0007] Preferably, the first reversing pole is affixed with reflective stickers, and there are multiple reflective stickers.

[0008] Preferably, the disassembly and assembly mechanism includes a rotating rod fixedly installed in the mounting groove, a fixing plate rotatably mounted on the rotating rod, a torsion spring fixedly installed in the mounting groove, and the other end of the torsion spring fixedly mounted on the fixing plate.

[0009] Preferably, a locking block is fixedly installed on the side of the fixing plate near the first reversing pole, and a fixing hole is provided on the first reversing pole.

[0010] Preferably, the first reversing lever has a first reserved hole, the mounting block has a second reserved hole, a pressing block is slidably installed in the second reserved hole, and the pressing block is fixedly installed on the other side of the fixing plate.

[0011] The beneficial effects of this utility model are:

[0012] In this invention, through the design of the disassembly and assembly mechanism, when the first reversing lever is inserted into the mounting block, the first reversing lever will drive the locking block to rotate. The locking block will slide into the fixing hole and fix the first reversing lever in the mounting block. By pressing the pressing block, the first reversing lever can be pulled out from the mounting block. This design allows for quick disassembly and assembly of the first reversing lever, facilitating its replacement and assembly. At the same time, it can prevent the first reversing lever from being ejected from the mounting block and broken by the wheel when subjected to external force.

[0013] In this invention, the malleable iron base, rotating wheel, groove, and slide bar are designed to facilitate the movement of the malleable iron base by pushing the first reversing lever. The groove makes it easier to move the malleable iron base to the required position. This design allows for convenient transfer and handling of the malleable iron base, saving physical effort and improving training efficiency. Attached Figure Description

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0020] Example:

[0021] like Figure 1-4 As shown, this embodiment provides a novel reversing pole structure for special vehicle driving training, including a malleable iron base 1, a rotating wheel 2 rotatably installed inside the malleable iron base 1, a groove 3 formed on the malleable iron base 1, an installation block 4 fixedly installed on the top of the malleable iron base 1, a disassembly and assembly mechanism 5 provided inside the installation block 4, a first reversing pole 6 slidably installed inside the installation block 4, a connecting pipe 7 fixedly installed on the top of the first reversing pole 6, a second reversing pole 8 snapped into the connecting pipe 7, a sliding strip 9 fixedly installed on the first reversing pole 6, an installation groove 10 formed inside the installation block 4, the sliding strip 9 slidably installed in the installation groove 10, and reflective stickers 11 affixed to the first reversing pole 6, with multiple reflective stickers 11;

[0022] The rotating wheel 2 allows the first reversing lever 6 to be pushed, which in turn moves the malleable iron base 1, making it easy to move the malleable iron base 1 to the desired position. The groove 3 makes it easier to move the malleable iron base 1. The second reversing lever 8 can be inserted into the malleable iron base 1 to connect the first reversing lever 6 and the second reversing lever 8 together. The sliding bar 9 makes it easier to fix the first reversing lever 6. This design facilitates the transfer and handling of the malleable iron base 1, saving physical effort and improving training efficiency. The malleable iron base 1 makes the device more stable overall, and its shape is more in line with the tire, preventing it from being crushed and increasing its load-bearing capacity. The disassembly and assembly mechanism 5 allows for quick disassembly and assembly of the first reversing lever 6 from the mounting block 4, facilitating the replacement and assembly of the first reversing lever 6. It also prevents the first reversing lever 6 from popping out of the mounting block 4 and being crushed by the wheel when subjected to external force. The reflective sticker 11 serves as a warning, making it easier for trainees to observe the positions of the first reversing lever 6 and the second reversing lever 8.

[0023] In this embodiment of the utility model, specifically, the disassembly and assembly mechanism 5 includes a rotating rod 51 fixedly installed in the mounting groove 10, a fixing plate 52 rotatably installed on the rotating rod 51, a torsion spring 53 fixedly installed in the mounting groove 10, the other end of the torsion spring 53 fixedly installed on the fixing plate 52, a locking block 54 fixedly installed on the side of the fixing plate 52 near the first reversing lever 6, a fixing hole 55 is opened on the first reversing lever 6, a first reserved hole 56 is opened on the first reversing lever 6, a second reserved hole 57 is opened on the mounting block 4, a pressing block 58 is slidably installed in the second reserved hole 57, and the pressing block 58 is fixedly installed on the other side of the fixing plate 52;

[0024] To quickly remove and install the first reverse lever 6 from the mounting block 4, align the slide bar 9 with the mounting groove 10 and insert the first reverse lever 6 into the mounting block 4. The first reverse lever 6 will cause the locking block 54 to rotate, pushing the locking block 54 open. When the locking block 54 slides into the fixing hole 55, due to the setting of the torsion spring 53, the locking block 54 will be fixed in the fixing hole 55, thereby fixing the first reverse lever 6 in the mounting block 4. Press the pressing block 58, and the pressing block 58 will drive the fixing plate 52 to rotate, and the rotation of the fixing plate 52 will drive... When the locking block 54 rotates, it moves out of the fixing hole 55, allowing the first reversing lever 6 to be pulled out from the mounting block 4. This design allows for quick disassembly and assembly of the first reversing lever 6, facilitating its replacement and reassembly. It also prevents the first reversing lever 6 from being ejected from the mounting block 4 and broken by the wheel when subjected to external force. The first reserved hole 56 provides sufficient space for the fixing plate 52 to rotate, and the second reserved hole 57 provides sufficient space for the pressing block 58 to rotate downwards.

[0025] Working principle: During use, the rotating wheel 2 pushes the first reversing lever 6, which in turn moves the malleable iron base 1, facilitating its movement to the desired position. The groove 3 further enhances the ease of transporting the malleable iron base 1. Inserting the second reversing lever 8 into the malleable iron base 1 connects the first and second reversing levers 6. The sliding bar 9 makes fixing the first reversing lever 6 easier. This design facilitates the transfer and transport of the malleable iron base 1, saving energy and improving training efficiency. Aligning the sliding bar 9 with the mounting slot 10 and inserting the first reversing lever 6 into the mounting block 4 causes the first reversing lever 6 to move the locking block 5. 4. Rotate to push the locking block 54 open. When the locking block 54 slides into the fixing hole 55, the torsion spring 53 will fix the locking block 54 in the fixing hole 55, thereby fixing the first reversing lever 6 in the mounting block 4. Press the pressing block 58, and the pressing block 58 will drive the fixing plate 52 to rotate. The rotation of the fixing plate 52 will drive the locking block 54 to rotate. The locking block 54 will rotate out of the fixing hole 55, and the first reversing lever 6 can be pulled out from the mounting block 4. This setting allows for quick disassembly and assembly of the first reversing lever 6, making it convenient to replace and assemble the first reversing lever 6. At the same time, it can prevent the first reversing lever 6 from being pushed out of the mounting block 4 and broken by the wheel when subjected to external force.

[0026] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
