SUMMARY

[0005] The utility model provides a kind of foldable wheel stopper for the above problems existing in prior art, the technical problems to be solved by the utility model are: improve the operation convenience of wheel stopper.

[0006] The purpose of the utility model can be realized by the following technical schemes:

[0007] A kind of foldable wheel stopper, including strip-shaped front leg and strip-shaped rear leg, the upper end of the front leg is hinged with the upper end of the rear leg, characterized in that, wheel stopper further includes one end hinged pull rod one and pull rod two, the other end of the pull rod one is hinged at the lower end of the front leg, the other end of the pull rod two is hinged on the rear leg, when the front leg and rear leg are close to each other, the pull rod one and the pull rod two can be folded.

[0008] By connecting the two hinged pull rods one and two between the lower end of the front leg and the rear leg, when the wheel stop is opened, only the pull rods one and two need to be tensioned to form a line, which means that the opening angle of the front leg and the rear leg is stable to form a triangular structure, without the need for special alignment and without the need for the use of a large cap to fix it. When the wheels of the car act on the front leg, the downward pressure makes the front leg and the rear leg have a tendency to open, and the pull rods one and two remain tensioned to meet the stable wheel stopping needs, making it more convenient to use when opened; when it needs to be stored, control the front leg and the rear leg to close, and make the hinge points of the pull rods one and two arch upward, control the front leg and the rear leg to close, and make the pull rods one and two also be forced to finally form a fold, which is achieved by one force, the steps are more simple and the operation is more convenient. The front leg and the rear leg close to each other effectively reduces the space occupied by the wheel stop. The pull rods one and two used to maintain the open state of the front leg and the rear leg can accommodate the space between the front leg and the rear leg after folding, making the space utilization rate higher when the wheel stop is stored, and the storage is more efficient and convenient.

[0009] In the above foldable wheel stop, the cross sections of the front leg and the rear leg are U-shaped, and the pull rods one and two are located in the space formed by the folding of the front leg and the rear leg when the front leg and the rear leg are closed to each other and mutually engaged. When the storage is completed, the U-shaped front leg and rear leg form a relatively closed and stable cavity, which can accommodate the folded pull rods one and two, achieving more effective protection and shielding, and improving the storage effect.

[0010] In the above foldable wheel stop, the wheel stop further comprises a horizontally arranged positioning plate having a vertically arranged cylindrical sleeve on the positioning plate, and the positioning plate is connected to the lower end of the rear leg. The sleeve on the positioning plate facilitates the user to drive the pin into the lower wood plate through the sleeve to fix the positioning plate, thereby effectively restricting the position of the rear leg to ensure the supporting effect of the wheel stop.

[0011] In the above foldable wheel stop, the length of the rear leg is less than the length of the front leg, and the positioning plate further has a U-shaped connecting seat, and the lower end of the rear leg is hinged to the connecting seat and can be flipped backward relative to the connecting seat. In this way, the length of the rear leg is smaller, which is beneficial to reduce the slope of the opening of the front leg, so that the front leg maintains a stable structure under the downward load when forming a wheel stop. The lower end of the rear leg is hinged to the connecting seat, which is beneficial to flip the connecting seat backward to drive the positioning plate to swing backward when storing, avoiding interference between the positioning plate and the front leg during folding to affect normal storage, ensuring the compact storage effect, and the space in the middle of the U-shaped connecting seat can provide space for the pull rod one or the rear leg.

[0012] In the foldable wheel stopper, the horizontal width dimension of the rear legs is smaller than the width dimension of the front legs, the lower end of the rear legs is fork-shaped and forms two horizontally opposite clamping plates, the connecting seat is hinged between the two clamping plates, and the outer side of the connecting seat is provided with a limiting surface, and the side edges of the clamping plates can abut against the limiting surface to prevent the bottom of the connecting seat from being flipped forward relative to the clamping plates. In this way, the strength of the front leg structure directly subjected to pressure is higher, and when the rear leg is subjected to load and flipped forward relative to the connecting seat, the limiting surface can provide blocking and sufficient support, so that the hinge shaft of the clamping plate and the connecting seat is not subjected to excessive load, and meanwhile, the connecting seat can be flipped backward from the space between the two clamping plates during storage, so that interference is avoided during flipping, and the storage operation is smoother.

[0013] In the foldable wheel stopper, the front legs and the rear legs are both two, the upper and lower ends of the two front legs are fixed by the cross beam to form a frame shape, and the lower ends of the two rear legs are connected with the positioning plate. In this way, the frame-shaped structure formed by the two front legs can provide a larger wheel stopping area while ensuring structural stability, and the linkage structure formed by the two rear legs ensures the consistency of the operation, so that the storage is more convenient.

[0014] In the foldable wheel stopper, the pin sleeve is located between the lower ends of the two rear legs. In this way, the pin sleeve can be misaligned with the front legs during storage to avoid interference during storage, and the pin sleeve can be stored in the space between the two rear legs after being flipped with the positioning plate, so that the storage compactness is improved.

[0015] Compared with the prior art, the foldable wheel stopper has the following advantages:

[0016] When the foldable wheel stopper is used, the front legs and the rear legs are only needed to be spread apart by the pull rod one and the pull rod two to be limited to a predetermined angle, so that the placement and use requirements are met. When storage is needed, the front legs and the rear legs are brought close to each other, so that the folding of the pull rod one and the pull rod two is simultaneously realized, and the storage is completed, so that the operation is more convenient and efficient.
