Description

Technical Field

[0001] This utility model belongs to the field of handcart technology, specifically relating to a reverse lever transfer and storage cart. Background Technology

[0002] Driving skills (commonly known as driving skills) are a craft and skill that requires repeated practice and continuous improvement. During driving practice, reversing poles (referred to as reversing poles) are usually used. A reversing pole consists of a horizontal chassis and a vertical pole inserted above the chassis. The outer surface of the pole is usually wrapped with reflective stickers at intervals. Especially when reversing large freight vehicles such as military trucks into parking spaces, due to the long length of the vehicle body, it is more difficult to observe with the rearview mirror. For new learners, it is even more necessary to set up relatively conspicuous reversing poles. However, due to the large number of parking spaces and the large area of ​​the parking lot for centralized training, the number of reversing poles needed is large and scattered, making the transportation and placement of reversing poles a time-consuming and laborious task. Currently, the placement of parking barriers still relies entirely on manual transport and placement. Each person can usually only carry two barriers at a time. After placing them at the entrance of a parking space, they have to go back to get another set of barriers. This back-and-forth running around is physically demanding, and the efficiency of setting up the barriers is also low. Moreover, when collecting the barriers after practice, the reverse operation has to be repeated several times, which is very time-consuming and laborious. Furthermore, the collected barriers take up a large area of ​​ground when laid out, and when piled up, they look messy and are not easy to retrieve and use next time. Utility Model Content

[0003] In response to the above situation, this utility model provides a reverse pole transfer and storage vehicle, which can help personnel quickly and efficiently complete the placement and retrieval of reverse poles.

[0004] To achieve the above objectives, the present invention adopts the following technical solution:

[0005] A reverse pole transfer and storage cart includes a trolley and a reverse pole placed on the trolley. The trolley includes a vertical frame and a push-pull handle welded to the front side of the vertical frame. Multiple horizontal frames of decreasing length are welded at intervals from bottom to top on the rear side of the vertical frame. The bottom horizontal frame has casters installed at the four corners. Multiple chassis clamps are arranged along the width direction above the rear of each of the other horizontal frames (excluding the top one) for positioning and clamping the chassis of the reverse pole. Multiple upright clamps corresponding to each of the chassis clamps are provided at the rear of each of the other horizontal frames (excluding the bottom one) for positioning and clamping the uprights of the reverse pole.

[0006] Furthermore, the chassis clamp includes a circular horizontal mounting plate and a plurality of C-shaped clamping arms evenly distributed in a ring above the circumferential edge of the horizontal mounting plate. The diameter of the horizontal mounting plate is larger than the diameter of the chassis of the reversing lever. The openings of each C-shaped clamping arm face the chassis. When the reversing lever is placed, the circumferential edge of the chassis is placed inside the openings of each C-shaped clamping arm. The middle part of each C-shaped clamping arm is rotatably hinged to the horizontal mounting plate through a hinge seat. A longitudinally rotatable pressure wheel is installed at the upper end of each C-shaped clamping arm, and a return spring is connected between the lower end of each C-shaped clamping arm and the horizontal mounting plate.

[0007] Preferably, the clamping wheel is a columnar rubber roller with a plum blossom-shaped cross-section, and its two ends are rotatably connected to a C-shaped clamping arm via a central shaft.

[0008] Preferably, the reset spring is a retractable flexible spring, with its two ends fixedly connected to the lower end of the C-shaped clamping arm and the upper surface of the horizontal mounting plate, respectively.

[0009] Furthermore, the pole clamp includes an installation body and two elastic arms integrally fixed to the left and right ends of the installation body. The two elastic arms are symmetrically arranged in a figure-eight shape. The ends of the two elastic arms away from the installation body are close to each other and each is equipped with a clamping wheel that can rotate laterally. An anti-slip pad is provided in the middle of the ends of the two elastic arms close to the installation body.

[0010] Preferably, the clamping wheel is a columnar rubber roller with a plum blossom-shaped cross-section, and its two ends are rotatably connected to the elastic clamping arm through a spindle.

[0011] Preferably, the anti-slip pad is made of elastic silicone strip with a certain degree of stretchability, and its two ends are fixedly connected to the two elastic arms respectively.

[0012] This utility model also includes other components that enable its normal use, all of which are conventional means in the field. In addition, devices or components not limited in this utility model, such as the chassis and upright of the reversing pole, as well as casters, return springs, clamping wheels, pressure wheels and upright clamps, all adopt the prior art in the field.

[0013] The beneficial effects of this utility model are as follows:

[0014] This utility model provides a reverse pole transfer and storage cart, which can help personnel transfer many reverse poles at once, and facilitates the quick and efficient placement and retrieval of reverse poles. The cart is easy to push and pull, which can effectively improve the placement efficiency of reverse poles, saving time and effort. Moreover, one cart can arrange and store many reverse poles in multiple layers, and storage can be done without getting off the cart, which saves space, keeps things neat and orderly, and makes it convenient to retrieve them next time.

[0022] Example

[0023] like Figure 1-5 As shown, a reversing pole transfer and storage vehicle includes a trolley and a reversing pole placed on the trolley. The trolley includes a vertical frame 1 and a push-pull handle 2 welded to the front side of the vertical frame. Multiple horizontal frames 3 with decreasing lengths are welded at intervals from bottom to top on the rear side of the vertical frame. Universal wheels 4 are installed at the four corners of the bottom horizontal frame. Multiple chassis clamps 5 are arranged along the width direction on the upper rear part of each horizontal frame except the top one, for positioning and clamping chassis 101 of the reversing pole. Multiple upright clamps 6, corresponding to each chassis clamp, are provided at the rear end of each horizontal frame except the bottom one, for positioning and clamping uprights 102 of the reversing pole.

[0024] The chassis clamp includes a circular horizontal mounting plate 501 and a plurality of C-shaped clamping arms 502 evenly distributed in a ring above the circumferential edge of the horizontal mounting plate. The diameter of the horizontal mounting plate is larger than the diameter of the chassis of the reversing lever. The openings of each C-shaped clamping arm face the chassis. When the reversing lever is placed, the circumferential edge of the chassis is placed inside the openings of each C-shaped clamping arm. The middle part of each C-shaped clamping arm is rotatably hinged to the horizontal mounting plate through a hinge seat 503. A longitudinally rotatable pressure wheel 504 is installed at the upper end of each C-shaped clamping arm. A return spring 505 is connected between the lower end of each C-shaped clamping arm and the horizontal mounting plate.

[0025] The clamping wheel is a columnar rubber roller with a plum blossom-shaped cross-section, and its two ends are rotatably connected to the C-shaped clamping arm through the central shaft 506.

[0026] The reset spring is a retractable flexible spring, with its two ends fixedly connected to the lower end of the C-shaped clamping arm and the upper surface of the horizontal mounting plate, respectively.

[0027] When the reverse lever is placed from top to bottom onto the chassis clamp, the lower edge of the reverse lever's chassis first contacts the inner surface of each clamping roller. Then, each clamping roller rotates up and down, while the upper ends of each C-shaped clamping arm open outwards slightly, allowing the chassis to smoothly enter between the C-shaped clamping arms of the chassis clamp. As the chassis continues to press down, the lower ends of each C-shaped clamping arm are pressed down, and the upper ends of each C-shaped clamping arm also pry downwards to press against the upper surface of the chassis. Moreover, the upper surface of the reverse lever's chassis is generally a sloped surface with a higher center and lower perimeter. Therefore, the clamping rollers at the upper ends of each C-shaped clamping arm can press against the upper surface of the chassis very well. Even after the reverse lever is released, the clamping rollers can still maintain the state of pressing against the chassis due to the reverse lever's own weight. When a person takes the reversing lever, the components of the chassis clamp move in the opposite direction. After the reversing lever is removed, the return spring automatically resets, restoring each clamping wheel to its initial open state.

[0028] The pole clamp includes a mounting body 601 and two elastic arms 602 integrally fixed to the left and right ends of the mounting body. The two elastic arms are symmetrically arranged in a figure-eight shape. The ends of the two elastic arms away from the mounting body are close to each other and each is equipped with a clamping wheel 603 that can rotate laterally. An anti-slip pad 604 is provided in the middle of the ends of the two elastic arms near the mounting body. The structure and principle of the pole clamp are similar to those of a mop clamp disclosed in the prior art patent document CN213821278U, and will not be described in detail here.

[0029] The clamping wheel is a columnar rubber roller with a plum blossom-shaped cross-section, and its two ends are rotatably connected to the elastic arm via a spindle 605.

[0030] The anti-slip pad is made of elastic silicone strips with a certain degree of stretchability, and its two ends are fixedly connected to the two elastic arms respectively.

[0031] After the chassis of the reversing lever is firmly positioned inside the chassis clamp, align the upright of the reversing lever with the opening between the two clamping wheels of the upright clamp, and push it from back to front into the triangular encircling space formed by the two clamping wheels and the anti-slip pad. Release the reversing lever, and its upright will be stably clamped and positioned in the center of the upright clamp. At this point, the chassis of the reversing lever is stably secured in the center of the chassis clamp, and the upright of the reversing lever is stably secured in the center of the upright clamp, thus working together to stably clamp the entire reversing lever. Even when the trolley is being pushed or pulled at high speed, the reversing levers will remain neatly and stably upright on the trolley without wobbling or tipping over.

[0032] The technical solution of this utility model is not limited to the specific embodiments described above. Without departing from the scope and spirit of the described embodiments, many modifications and changes will be obvious to those skilled in the art. Any technical modifications made within the spirit and principles of this utility model shall fall within the protection scope of this utility model.
