[0002] The axle of a car is mainly used to bear the load of the vehicle to maintain the normal driving of the car on the road. The axle of the car needs to be transported with the help of a transport rack, and the axle is fixed on the transport rack for transportation to reduce bumps. In order to facilitate the stacking of transport racks and improve space utilization, the existing transport racks usually include a base and several support columns vertically fixed on the base. The base is used to support and fix the axle, and the several support columns of the lower transport rack are suitable for cooperating with the base of the upper transport rack. However, in order to avoid bumping the axle, the top height of the support column is usually higher than the height of the axle on the base, resulting in a larger size of the transport rack in the vertical direction. When the transport rack is in an empty state, it takes up a lot of space, which is not conducive to storage in a limited space.

[0003] Therefore, it is necessary to improve the prior art to overcome the above defects. Utility Model Content

[0020] Further, the notch of the support faces the support adjacent to the support in a clockwise direction; or,

[0021] The notch of the support faces the support adjacent to the support in a counterclockwise direction.

[0022] Furthermore, the mounting groove is a square groove, the support column is a square column adapted to the mounting groove, and the lower end surface and the side surface of the support column are directly connected.

[0023] Furthermore, the connection hole is a circular hole; or, the connection hole is a strip-shaped hole whose length direction is parallel to the vertical direction.

Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of this application.

[0034] As used herein, the terms "comprise," "comprising," and "having," and any variations thereof, are intended to cover non-exclusive inclusions. For example, a process, method, system, product, or apparatus comprising a series of steps or elements is not limited to the listed steps or elements but may optionally include steps or elements not listed, or may optionally include other steps or elements inherent to the process, method, product, or apparatus.

[0035] References herein to "embodiments" mean that a particular feature, structure, or characteristic described in connection with the embodiments may be included in at least one embodiment of the present application. The appearance of this phrase in various places in the specification does not necessarily refer to the same embodiment, nor does it constitute an independent or alternative embodiment that is mutually exclusive of other embodiments. It is understood, both explicitly and implicitly, by those skilled in the art that the embodiments described herein may be combined with other embodiments.

[0036] See also Figures 1 to 4 As shown, a foldable transport frame corresponding to a preferred embodiment of the utility model is used to support and fix the axle to facilitate the centralized transportation of the axle. The transport frame includes a base 100, a support 200 and a support column 300. The base 100 is used to support and fix the axle (not shown in the figure), and the support 200 is fixed to the top of the base 100. There are multiple supports 200, and they are arranged at intervals along the circumference of the base 100. The support 200 is recessed inward from its side to form a mounting groove 210, and the mounting groove 210 passes through the top of the support 200 in the vertical direction. The support column 300 is suitable for vertically inserting into the mounting groove 210 from the top of the support 200. There are multiple support columns 300, and they correspond one to one to the support 200.

[0037] The transport rack further includes a guide structure supported between the support column 300 and the support 200. The support column 300 is adapted to translate under the guidance of the guide structure to a locked position close to the bottom of the mounting groove 210 or an unlocked position away from the bottom of the mounting groove 210. When the support column 300 is in the locked position, the support column 300 is adapted to remain in an upright position. When the support column 300 is in the unlocked position, the support column 300 is adapted to rotate from the notch of the mounting groove 210 toward the base 100. In this embodiment, the bottom of the mounting groove 210 specifically refers to the end surface of the mounting groove 210 at the end of the recess, and the notch of the mounting groove 210 is an open opening located on the side of the support 200 and opposite to the bottom of the groove.

[0038] The utility model sets a support 200, and the support 200 is recessed from its side to form a mounting groove 210, and the mounting groove 210 passes through the top of the support 200 in the vertical direction. The support column 300 can be vertically inserted into the mounting groove 210 from the top of the support 200 to support and position the support column 300; a guide structure is connected between the support column 300 and the support 200, and the support column 300 can be translated to a locking position close to the bottom of the mounting groove 210 or away from the bottom of the mounting groove 210 under the guidance of the guide structure. When the support column 300 is moved to the unlocked position, the support column 300 is suitable for being maintained in the first state of being upright on the base 100 under the limitation of the mounting groove 210, so that the transport rack can be stacked through the support column 300 during transportation. When the support column 300 is moved to the unlocked position, the support column 300 is not limited by the bottom of the mounting groove 210, so that it can be turned from the notch of the mounting groove 210 to the base 100, reducing the space occupied by the transport rack in the empty state, which is beneficial to the storage of the transport rack in a limited space.

[0039] Furthermore, a guide structure is located near the lower end of the support column 300. The guide structure includes a connection hole 220, a guide portion 310, and a connector 400. The connection hole 220 is formed through at least one horizontal side wall of the mounting slot 210. The guide portion 310 is recessed inward from the side of the support column 300 and corresponds to the connection hole 220. The connector 400 is fixedly inserted into the connection hole 220, at least partially positioned within the guide portion 310, and can translate along and rotate relative to the guide portion 310. With this structure, the guide portion 310 and the connector 400 are suitable for cooperating to guide the support column 300 along a predetermined path.

[0040] In one embodiment, the connection hole 220 only extends through one side wall of the mounting slot 210. However, with this structure, only one side of the support column 300 is connected to the guide structure, resulting in poor stability of the support column 300 after connection and hindering the guide structure from reliably guiding the translation and rotation of the support column 300. Preferably, in this embodiment, the connection hole 220 extends horizontally from one side wall of the mounting slot 210 to the other side wall, with the first hole portion 221 and the second hole portion 222 formed on each side wall of the mounting slot 210, respectively. This allows both sides of the support column 300 to connect with the guide structure, improving the stability of the support column 300 after connection and providing a better guiding effect of the guide structure.

[0041] Specifically, the guide portions 310 can be two slotted structures, each recessed inward from two opposing sides of the support column 300. Accordingly, the connectors 400 are two in number and positioned between the first hole portion 221 and one of the guide portions 310, and between the second hole portion 222 and the other of the guide portions 310. In this case, the connection hole 220 is a circular hole, and the connector 400 can be a threaded member such as a bolt or screw, which is threadedly connected to the connection hole 220. The head of the connector 400 is positioned in the guide portion 310 to guide and limit the support column 300. However, with the above structure, the installation of the guide structure is relatively complicated. Since the support 200 is formed with a mounting groove 210, which is a thin-walled structure, it is difficult to form a deeper connecting hole 220. The reliability of the connecting member 400 after connection is low, and the connecting member 400 is easy to loosen after the transport rack is used for a long time. In order to reduce the weight of the transport rack and reduce the cost, the support column 300 usually adopts a hollow thin-walled structure, which makes it difficult for the slotted guide part 310 to form a reliable depth to accommodate the connecting member 400.

[0042] As a preferred embodiment, the guide portion 310 is an open hole structure that passes through from one side of the support column 300 to the other side. The connector 400 is suitable for passing from the first hole portion 221 through the guide portion 310 into the second hole portion 222, so that there is no need to set up two connectors 400. The structure is simple and installation is convenient. The open hole guide portion 310 can reliably accommodate the connector 400, which is convenient for application to support columns 300 with hollow thin-walled structures. In this case, the connector 400 can be a threaded member such as a bolt, screw, or threaded rod, which can be axially movably inserted into the connecting hole 220 and the guide portion 310. The connecting hole 220 can be a circular hole or a strip hole with a length direction parallel to the vertical direction. Preferably, it is a strip hole, so that the position of the connector 400 in the vertical direction can be adaptively adjusted as needed, thereby adjusting the installation position of the support column 300. When the connector 400 is a bolt, screw, or other structure with a cap formed on one end, the cap of the connector 400 is located at the outer end of the first hole 221, and the head of the connector 400 extends out of the outer end of the second hole 222 and is threadedly connected to a lock nut 500. By tightening the lock nut 500, the support 200 is tightened between the cap of the connector 400 and the lock nut 500, thereby securing the connector 400 to the support 200. When the connector 400 is a threaded rod, its ends are respectively located at the outer ends of the first hole 221 and the second hole 222, and the lock nut 500 is threadedly connected to each end of the connector 400. The support 200 is tightened between the lock nuts 500 at both ends of the connector 400, thereby securing the connector 400 to the support 200. Obviously, compared to the guide portion 310 with a slotted structure, the guide portion 310 with an open hole structure facilitates the installation of the guide structure and has better reliability and adaptability after installation.

[0043] Furthermore, the guide portion 310 includes at least a horizontal section 311. When the support column 300 is in an upright position, the length of the horizontal section 311 is parallel to the recessed direction of the mounting slot 210. The horizontal section 311 has a first end 312 distal from the bottom of the mounting slot 210 and a second end 313 proximal to the bottom of the mounting slot 210. The support column 300 is adapted to move along the horizontal section 311 to a locked position or an unlocked position. The connector 400 is positioned at the first end 312 in response to the support column 300 moving to the locked position, and at the second end 313 in response to the support column 300 moving to the unlocked position. When the connector 400 is positioned in the horizontal section 311, a rotational clearance is provided between the lower end of the support column 300 and the vertical sidewalls of the mounting slot 210 to prevent rotation of the support column 300.

[0044] However, with the above structure, the support column 300 in the vertical state is prone to move along the recessed direction of the mounting groove 210 when subjected to a horizontal force, making the support column 300 in the locked position less reliable. Moreover, when there is a gap between the side of the support column 300 and the bottom of the mounting groove 210, it is difficult for the support column 300 to remain in a completely upright state, and the assembly requirements for the two are relatively high.

[0045] As a preferred embodiment, the guide portion 310 also includes a vertical section 314 extending upward from the first end 312 in a direction perpendicular to the horizontal section 311, and the vertical section 314 has a third end 315 away from the first end 312. The support column 300 in the locked position is suitable for moving downward along the vertical section 314 under the action of gravity so that the third end 315 moves toward the connecting member 400. With the above structure, when the support column 300 is in the locked position, the support column 300 drives the connecting member 400 to be in the vertical section 314 under the action of gravity, and the connecting member 400 can limit the support column 300 in the recessed direction of the mounting groove 210, so that the support column 300 in the locked position is not easy to move along the recessed direction of the mounting groove 210. When the support column 300 needs to be switched to the unlocked position, the support column 300 needs to be lifted up first so that the connecting member 400 is at the first end 312, and then the support column 300 is moved along the horizontal section 311 so that the connecting member 400 is at the second end 313, thereby effectively improving the reliability of the support column 300 in the locked position and improving its supporting effect.

[0046] Furthermore, the top of the support 200 is recessed inward to form at least one locking groove 230. A locking block 320 is protruding from the side of the support column 300, corresponding one-to-one with the locking groove 230. In response to the support column 300 moving downward along the vertical section 314, the connector 400 engages with the locking block 320, further securing the support column 300. The locking groove 230 and the connecting hole 220 are located on the same side, allowing the two opposing sidewalls of the locking groove 230 to reliably retain the locking block 320 in the recessed direction of the mounting groove 210. Furthermore, since the mounting groove 210 formed in the support 200 is a thin-walled structure, the locking groove 230 preferably has a through-hole structure in the direction of the connecting hole 220, facilitating the formation of the locking groove 230. There are two locking grooves 230, located on the side of the support 200 where the first hole portion 221 and the side where the second hole portion 222 are formed, respectively. Accordingly, there are two locking blocks 320, one corresponding to each of the locking grooves 230. In this embodiment, the locking grooves 230 are preferably V-shaped grooves, whose inner dimensions gradually decrease in the direction of their concavity. The outer contour of the locking block 320 matches the inner contour of the locking groove 230, so that the locking block 320 can be securely inserted into or removed from the locking groove 230.

[0047] Furthermore, when the support column 300 moves down to the extreme position along the vertical section 314, the support column 300 is supported on the side wall of the installation groove 210 opposite to the top of the support 200, and / or the support column 300 is supported on the connecting piece 400, and / or the support column 300 is supported on the locking groove 230, and the present invention does not limit this.

[0048] Furthermore, the mounting slot 210 is a square slot, and the support column 300 is a square column that matches the mounting slot 210, facilitating the insertion of the support column 300 into the mounting slot 210. Furthermore, the mounting slot 210 can reliably limit the horizontal position of the support column 300 and guide the support column 300 for translation along a predetermined direction. The lower end surface and the side surface of the support column 300 are directly connected, i.e., there is no chamfered structure between the two. This ensures that when the support column 300 is in the locked position, the bottom of the mounting slot 210 can always reliably block the side surface of the support column 300, preventing the support column 300 from rotating.

[0049] Furthermore, the base 100 is a square frame, which facilitates the orderly horizontal arrangement of transport racks and creates a more compact space between adjacent transport racks, thereby improving space utilization during transport of the racks. The base 100 is provided with support blocks 110 for supporting and positioning the axles. Support blocks 110 can be made of materials such as rubber and silicone to prevent damage to the axles. Axles placed on support blocks 110 are securely positioned horizontally, ensuring reliable positioning during transport.

[0050] There are four supports 200, distributed at different corners of the base 100. The bottom of the base 100 is provided with embedding holes (not shown) that correspond one-to-one with the support columns 300. The upper ends of the multiple support columns 300 of the lower transport rack can be embedded in the different embedding holes of the base 100 of the upper transport rack to ensure the stability of the transport racks after stacking. Preferably, the upper ends of the support columns 300 are detachably mounted with pads 330. The pads 330 can be made of materials such as rubber and silicone to cushion the transport racks during stacking and prevent damage. The pads 330 also have relatively high friction, which can make the stacked transport racks more stable.

[0051] Furthermore, a receiving area 600 is formed between two adjacent supports 200. Multiple support columns 300 are adapted to be folded and accommodated in different receiving areas 600, with the upper ends of the support columns 300 supported on the top of the side of the base 100. Specifically, the notches of a support 200 face the support 200 adjacent to it clockwise; alternatively, the notches of a support 200 face the support 200 adjacent to it counterclockwise. That is, the notches of the multiple supports 200 all face different directions: the notches of two adjacent supports 200 face perpendicularly to each other, while the notches of two diagonally opposite supports 200 face opposite directions. Because the length of the support columns 300 is limited by the spacing between the two adjacent supports 200, compared to folding two adjacent support columns 300 and accommodating them in the same receiving area 600, the solution of the present invention allows the support columns 300 to have a wider range of optional lengths, adapting to axles of various heights.

[0052] The use process of the transport rack of the present invention is as follows: when the axle needs to be transported, the transport rack in the folded state is unfolded, first the support column 300 is rotated upward to the upright state, then the support column 300 is moved along the horizontal section 311 toward the bottom of the installation groove 210, and when the connecting member 400 is at the first end 312, the support column 300 is suitable for moving downward along the vertical section 314 under the action of gravity, during this process, the third end 315 gradually moves toward the connecting member 400, and the locking block 320 gradually snaps into the locking block 320 until the support column 300 moves down to the limit position, and each support column 300 repeats the above action until After each support column 300 is unfolded, the transport rack is unfolded; when the transport axle is no longer needed, the transport rack in the unfolded state is folded. First, the support column 300 is lifted up along the vertical section 314, the locking block 320 disengages from the locking groove 230, and the connecting piece 400 is at the first end 312. Then, the support column 300 is moved along the horizontal section 311 in the direction away from the bottom of the installation groove 210 until the connecting piece 400 is at the second end 313. At this time, the support column 300 can be flipped and folded toward the base 100. The above actions are repeated for each support column 300 until each support column 300 is folded, and the folding of the transport rack is completed.

[0053] The above description is only an implementation method of the present application and does not limit the patent scope of the present application. Any equivalent structure or equivalent process transformation made using the contents of the description and drawings of this application, or directly or indirectly applied in other related technical fields, are also included in the patent protection scope of the present application.
