Abstract
Description
Technical Field
[0001] This utility model relates to a tie rod structure for a tie rod cart and a tie rod cart. Background Technology
[0002] The most common trolleys on the market are usually composed of a handlebar, a body, and casters. The body is used to place items, and the handlebar allows users to move the trolley without bending over.
[0003] In the use of trolleys, the handle is usually arranged perpendicularly to the body. Therefore, trolleys with handles are typically fixedly connected to the body and arranged perpendicularly. Such trolleys cannot be directly disassembled for storage and take up a lot of space during transportation. Even when not in use, trolleys still occupy a lot of living space, causing great inconvenience for storage. Trolleys with adjustable handle angles have also appeared on the market. However, since the handle is usually arranged perpendicularly to the body, the angle between the two cannot be stably fixed, and the handle angle is prone to swinging, resulting in a poor user experience. Utility Model Content
[0004] The purpose of this utility model is to provide a tie rod structure and a tie rod cart to solve at least one of the above-mentioned technical problems.
[0005] According to one aspect of the present invention, a tie rod structure for a trolley is provided, which is disposed between the trolley body and the tie rod, comprising:
[0006] Mounting bracket for mounting tie rods, the mounting bracket has through holes;
[0007] A base for mounting on a vehicle body, a mounting seat is disposed on the base and rotatably connected to the base, and the base is provided with a cavity; and
[0008] Insert plate, insert plate is inserted into the through hole, insert plate is inserted into the cavity.
[0009] This utility model discloses a pull rod structure for a trolley. The pull rod is mounted on a mounting base, and the base is mounted on the trolley's body. Because the mounting base and the base are rotatably connected, during transportation or when storage is required, the insert plate can be pulled out from the insert cavity, allowing the pull rod mounted on the mounting base to be flipped and folded onto the trolley's body. This reduces the space occupied by the trolley and facilitates transportation or storage. In addition, during use, the mounting base can be fixed to the base via the insert plate, forming a stable angle between the pull rod on the mounting base and the trolley's body. This ensures that the angle between the pull rod and the trolley is firmly fixed when the pull rod is arranged perpendicularly to the trolley body, preventing angular swaying during use and providing a better user experience.
[0010] In some embodiments, the mounting base may have at least a pair of parallel lugs, one of which has a protrusion on its sidewall near the other lug. The base has a hinge portion that is accommodated between the two lugs, and the two lugs are rotatably connected to the hinge portion. The sidewall of the hinge portion has an arc-shaped toothed band, and the protrusion engages with the toothed band.
[0011] When the mounting base rotates relative to the base, the protrusion can be displaced from one recess of the toothed belt to another recess.
[0012] Thus, through the cooperation of the lug and the hinge, the mounting base can rotate on the base. Through the cooperation of the protrusion and the toothed belt, when the pull rod on the mounting base is rotated, the pull rod can be suspended at any position. The user can pull the insert plate out of the insert cavity according to the needs of the usage scenario, and then adjust the angle between the pull rod and the vehicle body.
[0013] In some embodiments, the mounting base may have two pairs of parallel lugs, and the number of hinges is two. One pair of parallel lugs is located at one end of the mounting base, and the other pair of parallel lugs is located at the other end of the mounting base.
[0014] A hinge is housed between a pair of lugs, which are rotatably connected to the hinge.
[0015] Another hinge is housed between another pair of lugs, which are rotatably connected to the hinge.
[0016] Thus, the two pairs of lugs respectively engage with the two hinges, allowing the mounting base to rotate smoothly on the base.
[0017] In some implementations, snap-fit protrusions may be provided on both sides of the insert plate.
[0018] Therefore, the snap-fit protrusion ensures that the insert plate will not easily fall out when it is inserted into the perforation and cavity.
[0019] In some embodiments, the sidewall of the perforation may be provided with a snap-fit groove, and the insert plate may be provided with a buckle.
[0020] When the insert plate is inserted into the through hole and into the cavity, the clip engages in the engagement groove.
[0021] Therefore, the cooperation between the buckle and the slot can further ensure that the plug-in plate inserted into the hole and cavity will not easily fall out.
[0022] In some implementations, the insert plate may be provided with a clip.
[0023] Therefore, when it is necessary to remove the insert plate from the cavity and the perforation, the insert plate can be easily removed by using the prying part.
[0024] In some implementations, one end of the insert plate may be folded up.
[0025] Therefore, one end of the tapered insert can easily pass through the perforation and be inserted into the cavity.
[0026] According to another aspect of the present invention, a pull rod vehicle is also provided, including a vehicle body, a pull rod, and the above-described pull rod vehicle pull rod structure, wherein the pull rod is disposed on a mounting base and the base is disposed on the vehicle body.
[0027] This utility model of a trolley allows the insert plate to be pulled out of the insert cavity during transportation or when storage is required, and the trolley rod can be flipped and folded onto the vehicle body, reducing the space occupied by the trolley rod and facilitating transportation or storage. In addition, during use, the mounting base can be fixed to the base through the insert plate, so that the trolley rod and the vehicle body form a stable angle. When the trolley rod and the vehicle body are arranged perpendicularly, the angle between them is firmly fixed, ensuring that the trolley rod will not swing during use, thus providing a better user experience.
[0028] In some implementations, L-shaped protrusions may be provided at all four corners of the vehicle body.
[0029] Therefore, the raised edge ensures that items placed on the vehicle body will not easily slip off the side of the vehicle body.
[0030] In some implementations, the bottom of the vehicle body may be equipped with detachable casters with brakes.
[0031] Therefore, the casters can be removed during transportation or when storage is required, further reducing the space occupied by the product. Moreover, when the trolley needs to be fixed in a certain position during use, the casters can be braked to ensure that the vehicle body will not move easily. Attached Figure Description
