Description

Technical Field

[0001] This application relates to the field of parking assistance equipment, and in particular to a convenient wheel fixing device for oil tankers. Background Technology

[0002] Gas stations are retail outlets that supply gasoline and engine oil to cars and other motor vehicles. Refineries refine oil extracted from oil fields into gasoline, which is then transported to oil depots via pipelines, tankers, or trains. From there, it is transported by tanker trucks to gas stations and stored in underground storage facilities. During refueling, the gasoline is pumped out. When a tanker truck is fully loaded, its mass and inertia are enormous, resulting in a significant load on the braking system. To ensure stability and prevent rollover, the tanker truck must maintain constant braking, especially on uneven terrain. Prolonged exposure to this heavy load can reduce the lifespan of the braking system and even lead to brake failure. Wheel securing devices are typically used on tanker trucks at gas stations to maintain wheel stability.

[0003] Chinese Patent CN218400504U discloses a wheel-fixing device for tanker trucks at gas stations. The device includes a crossbeam, with a mounting block fixedly connected to the end of the crossbeam. A stop block is welded to the outer side of the mounting block. A roller bracket is fixedly installed at the bottom of the crossbeam, and a traveling wheel is movably sleeved at the bottom of the roller bracket. A first support rod is fixedly connected to the top of the crossbeam, and a handle ring is welded to the top of the first support rod. This wheel-fixing device for tanker trucks at gas stations, by placing the stop blocks on the front and rear sides of the tanker truck wheels, can limit and fix the wheels, preventing them from moving forward or backward. This eliminates the need for the tanker truck to be constantly braked, reducing the burden on the tanker truck's braking system and extending its service life.

[0004] Regarding the aforementioned technologies, the positions of the two blocks are fixed, and there is a possibility of a large gap between them, resulting in a significant space occupation. Utility Model Content

[0005] To reduce space requirements, this application provides a convenient wheel fixing device for oil tankers.

[0006] The present application provides a convenient wheel fixing device for oil tankers, which adopts the following technical solution: A convenient wheel fixing device for oil tankers includes a support rod and two stops. Each stop is connected to one end of the support rod. The two stops are spaced apart to form a positioning cavity for placing the tire. The two stops are respectively used to contact the two sides of the tire. The two support rods are hinged to each other.

[0007] By adopting the above technical solution, when in use, the two support rods rotate and unfold around the hinge point, so that the two blocks fit against the two sides of the tire to fix the tire. When not in use, they can be rotated and folded to reduce the volume, thereby reducing the space occupied and improving the portability.

[0008] Optionally, a locking element is provided between the two support rods for locking the two support rods.

[0009] By adopting the above technical solution, when using the device, after adjusting the included angle of the two support rods, the locking component will lock the support rods, thereby minimizing the risk of accidental rotation of the support rods during use and improving the stability of the stop block in fixing the tire.

[0010] Optionally, the bottom of the stop is connected to a roller.

[0011] By adopting the above technical solution and adding rollers, the device can be moved and transported more easily, reducing the effort required by operators and improving ease of use.

[0012] Optionally, a handle is attached to the end of the support rod away from the stop.

[0013] By adopting the above technical solution, when in use, the operator holds the handle to push or move the device, which facilitates the movement and directional control of the device, further improving the convenience of carrying and operation.

[0014] Optionally, the stop block has a contact surface at one end near the positioning cavity. The contact surface is inclined and is used to contact the tire. The stop block has several protrusions at one end of the contact surface, and the protrusions are used to contact the tire.

[0015] By adopting the above technical solution, when in use, the inclined contact surface fits the tire contour, and the raised strip increases the friction between the contact surface and the tire, thereby minimizing tire slippage on the stop block, improving the stability of the stop block in fixing the wheel, and enhancing safety performance.

[0016] Optionally, the support rod is connected to a rotating rod, and the end of the rotating rod away from the support rod is hinged to another rotating rod. A moving component is provided between the two support rods, and the moving component is used to drive the end of the rotating rod away from the support rod to move, thereby changing the included angle between the two support rods.

[0017] By adopting the above technical solution, when in use, the moving component drives the end of the rotating rod to move, causing the two support rods to rotate around the hinge point to change the included angle, thereby making it easier to adapt to the fixing requirements of tires of different sizes and improving the versatility of the device.

[0018] Optionally, a mounting plate is provided between the two support rods, the support rods are rotatably connected to the mounting plate, the movable component includes a threaded rod and a movable block, one end of the threaded rod passes through and is threadedly connected to the mounting plate, the movable block is rotatably connected to one end of the threaded rod, and the rotating rod is hinged to the movable block.

[0019] By adopting the above technical solution, when in use, rotating the threaded rod drives the moving block to move axially, the moving block drives the rotating rod to move, and the rotating rod pushes the support rod to rotate, thereby facilitating the adjustment of the included angle between the two rotating rods.

[0020] Optionally, the stop block is rotatably connected to the support rod, and the support rod is connected to a positioning component. The positioning component is used to position the stop block on the support rod. When the positioning component positions the stop block on the support rod, the contact surface is oriented towards the side closer to the positioning cavity.

[0021] By adopting the above technical solution, when not in use, rotating the support rod reduces the angle between the two support rods and folds them. At the same time, the stop block can be rotated and folded to reduce space occupation and facilitate the storage and transportation of the device. When in use, the stop block is positioned on the support rod by the positioning component to improve the connection stability between the stop block and the support rod.

[0022] Optionally, one end of the stop block is connected to a sleeve, and the support rod is rotatably connected inside the sleeve. The positioning component includes a spring and a locking block. The support rod has an installation groove on its periphery. One end of the spring is connected to the inner wall of the installation groove, and the other end of the spring is connected to the locking block. The sleeve has a locking hole on its periphery. The spring is used to drive the locking block to move and drive the locking block through the locking hole.

[0023] By adopting the above technical solution, when folding, pressing the locking block compresses the spring and disengages it from the locking hole, allowing the stop block to be rotated, thus facilitating the storage of the device. When in use, rotating the stop block brings the locking hole closer to the locking block. When the locking hole connects with the mounting groove, the spring pushes the locking block through the locking hole, thus ensuring that the stop block is stably connected to the support rod.

[0024] In summary, this application includes at least one of the following beneficial technical effects: 1. When in use, the two support rods rotate and unfold around the hinge point, so that the two stops fit against the two sides of the tire to fix the tire. When not in use, they can be rotated and folded to reduce the volume, thereby reducing the space occupied and improving the portability. 2. When in use, after adjusting the included angle of the two support rods, the locking device will lock the support rods to minimize the risk of accidental rotation of the support rods during use and improve the stability of the stop block in fixing the tire. 3. When folding, press the locking block to compress the spring and disengage it from the locking hole, then rotate the stop block to facilitate storage of the device. When in use, rotate the stop block so that the locking hole is close to the locking block. When the locking hole is connected to the mounting slot, the spring pushes the locking block through the locking hole, thus making the stop block stably connected to the support rod.

Detailed Implementation

[0030] The following is in conjunction with the appendix Figure 1-4 This application will be described in further detail.

[0031] Reference Figure 1 A convenient wheel fixing device for oil tankers includes two support rods 100 and stops 200. One support rod 100 is hinged to the middle of the other support rod 100. Each stop 200 is connected to the bottom end of its respective support rod 100. The two stops 200 are spaced apart and have positioning cavities 230 for placing the tire. Each stop 200 is designed to contact both sides of the tire. The two support rods 100 are hinged together, facilitating the storage of the device and reducing space requirements.

[0032] Reference Figure 1 A handle 110 is connected to the top of the support rod 100. A locking member 300 is provided between the two support rods 100 to lock the two support rods 100. The locking member 300 includes a bolt 310 and a nut 320. The bolt 310 passes through the two support rods 100 and is threadedly connected to the nut 320. One end of the nut 320 contacts the support rod 100.

[0033] Reference Figure 1 Two stops 200 have contact surfaces 210 near the positioning cavity 230. The contact surfaces 210 are inclined, with their tops tilted away from the positioning cavity 230. Several protrusions 220 are connected to one end of the contact surface 210 of each stop 200. The length of each protrusion 220 is aligned with the width of the stop 200, and the protrusions 220 are distributed along the extension direction of the contact surface 210. These protrusions 220 are used to contact the tire. A connecting groove 240 is formed at the bottom of each stop 200, and a roller 250, which is a swivel wheel, is connected to the inner wall of the connecting groove 240.

[0034] The implementation principle of Embodiment 1 of this application is as follows: When in use, rotate the support rod 100 to open the positioning cavity 230. When the positioning cavity 230 is opened to the size corresponding to the tire, rotate the bolt 310 to lock the support rod 100 with the nut 320, so as to facilitate the adaptation to different tire models. After use, rotate the bolt 310 to unlock the support rod 100 and rotate the support rod 100 to reduce the distance between the two stops 200, so as to facilitate the storage of the device and reduce the space occupied.

[0035] Example 2 The difference between this embodiment and Embodiment 1 is as follows: Reference Figure 2 and Figure 3 A rotating rod 120 is hinged to one end of the support rod 100 near the stop block 200, and the ends of the two rotating rods 120 away from the support rod 100 are hinged to each other. A mounting plate 130 is provided between the two support rods 100, and a rotating shaft 131 is connected to the mounting plate 130. The middle part of the support rod 100 is rotatably sleeved on the rotating shaft 131.

[0036] Reference Figure 2 and Figure 3 A movable assembly 400 is provided between the two support rods 100. The movable assembly 400 includes a threaded rod 410 and a movable block 420. One end of the threaded rod 410 passes through and is threadedly connected to the mounting plate 130. A rotating head 411 is connected to the top end of the threaded rod 410. The movable block 420 is rotatably connected to the bottom end of the threaded rod 410. The rotating rod 120 is hinged to the movable block 420.

[0037] Reference Figure 2 and Figure 4A stop block 200 is rotatably connected to a support rod 100. A sleeve 260 is connected to one end of the stop block 200 along its width direction. The length direction of the sleeve 260 is consistent with the width direction of the stop block 200. The bottom end of the support rod 100 is rotatably connected to the sleeve 260. A positioning assembly 500 is connected to the support rod 100. A mounting groove 140 is formed on the circumference of the support rod 100. The depth direction of the mounting groove 140 is consistent with the radial direction of the support rod 100. The positioning assembly 500 includes a spring 510 and a locking block 520. The length direction of the spring 510 is consistent with the depth direction of the mounting groove 140. One end of the spring 510 along its length direction is connected to the inner wall of the mounting groove 140, and the other end of the spring 510 is connected to the locking block 520. A locking hole 261 is formed on the circumference of the sleeve 260. The spring 510 is used to drive the locking block 520 to move and drive the locking block 520 through the locking hole 261.

[0038] The implementation principle of Embodiment 2 of this application is as follows: In use, rotating the rotating head 411 drives the threaded rod 410 to rotate and move it along its length. The moving block 420 moves with the threaded rod 410, and the moving block 420 drives the rotating rod 120 to move. The rotating rod 120 drives the support rod 100 to rotate, thereby adjusting the angle between the two support rods 100 and changing the size of the positioning cavity 230 to accommodate different tire models. When storing, rotating the support rod 100 brings the two stops 200 closer together. At the same time, pressing the locking block 520 causes it to embed into the mounting groove 140 and move away from the locking hole 261, facilitating the rotation of the stops 200 and thus facilitating the storage of the device and further reducing space occupation.

[0039] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
