DETAILED DESCRIPTION

[0040] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0041] Reference Figures 1 to 15 This embodiment provides a shelf quick assembly system, including a foot frame 1, a base plate 2, a sub-plate 3 and a locking device 4.

[0042] There are multiple tripods 1, and the tripods 1 are used to be fixed on the loading platform of the vehicle frame. The fixing method of the tripod 1 can be flexibly selected, such as fixing by screws, binding, etc. The base plate 2 is detachably mounted on the tripod 1 by a first fastener. After the tripod 1 is fixed on the loading platform, the floor is connected to the tripod 1 by the first fastener. The sub-board 3 is detachably mounted on the base plate 2. The sub-board 3 can be used directly to carry objects, or it can be connected to a tool for carrying objects (such as a basket). The locking device 4 is used to lock the relative position of the sub-board 3 and the base plate 2 to prevent the sub-board 3 from loosening. At least one of the tripod 1 and the base plate 2 is provided with a strip mounting hole 21, and the first fastener passes through the strip mounting hole 21.

[0043] The working principle of the shelf quick installation system in this embodiment is as follows:

[0044] In this embodiment, the position of the first fastener in the strip-shaped mounting hole 21 is adjustable, so that the relative distance between two adjacent tripods 1 can be adjusted, so that multiple tripods 1 can form different position distributions to adapt to different sizes of loading platforms and are easy to install.

[0045] As a possible example, in this embodiment, the sub-plate 3 is slidably mounted on the base plate 2, and the locking device 4 is used to restrict relative sliding of the sub-plate 3 and the base plate 2. Specifically, guide grooves 24 are provided on both sides of the base plate 2, and hook-shaped sliding portions 31 are provided on both sides of the sub-plate 3. The ends of the sliding portions 31 extend into and slide along the guide grooves 24. It will be understood that those skilled in the art could alternatively provide the guide grooves 24 on the sub-plate 3 and the sliding portions 31 on the base plate 2, as long as the sub-plate 3 and the base plate 2 can slide relative to each other.

[0046] There are many types of locking devices 4, and those skilled in the art can select one according to actual needs. For example, the locking device 4 is a locking screw that passes through the sub-plate 3 and is threadedly connected to the base plate 2 to lock the relative position of the sub-plate 3 and the base plate 2.

[0047] As a possible example, in this embodiment, the locking device 4 includes a locking pin 41 and a shifting mechanism. A through hole is provided on the base plate 2, and the locking pin 41 is slidably installed in the through hole. The shifting mechanism is connected to the locking pin 41 and is used to extend and retract the locking pin 41 into the through hole. A socket is provided on the sub-board 3, and when the part of the locking pin 41 extending out of the through hole is inserted into the socket, the relative position of the sub-board 3 and the base plate 2 is locked. After the sub-board 3 slides into place on the base plate 2, the locking pin 41 is controlled by the shifting mechanism to extend out of the through hole so that one end of the locking pin 41 is inserted into the socket. At this time, the sub-board 3 cannot slide relative to the base plate 2, and the relative position of the sub-board 3 and the base plate 2 is locked.

[0048] As a possible example, in this embodiment, the shift mechanism includes a spring 42 and a slider 43, and the spring 42 is located between the lock pin 41 and the base plate 2. One end of the spring 42 is connected to the lock pin 41, and the other end of the spring 42 is connected to the base plate 2. The slider 43 is slidably installed on the base plate 2, and the slider 43 is provided with an inclined surface 431, and the inclined surface 431 can be a plane or a curved surface. The lock pin 41 is provided with a protrusion 411 for sliding contact with the inclined surface 431. When the slider 43 slides along a first direction, the inclined surface 431 presses the lock pin 41 toward the spring 42, causing the spring 42 to contract and the lock pin 41 to be retracted into the through hole. When the slider 43 slides along a second direction, the spring 42 pushes the lock pin 41 out of the through hole. In this embodiment, the slider 43 slides along a straight line, and the second direction is opposite to the first direction.

[0049] The sliding position of the slider 43 can be controlled by manually moving the slider 43 or by other means.

[0050] As a possible example, in this embodiment, the shift mechanism further includes a rotating member 44, which is rotatably mounted on the base plate 2. A lever 441 is eccentrically mounted on the rotating member 44, and a slide groove 432 is provided on the slider 43. The lever 441 extends into the slide groove 432. As the rotating member 44 rotates, the lever 441 simultaneously slides along the slide groove 432. The lever 441 pushes against the sidewalls of the slide groove 432, causing the slider 43 to slide on the base plate 2. Through this connection structure, this embodiment converts the rotational motion of the rotating member 44 into linear motion of the slider 43.

[0051] As a possible example, in this embodiment, the shifting mechanism further includes a fixing member, which is used to fix the rotating member 44 to the base plate 2, preventing the rotating member 44 from rotating, thereby maintaining the locking pin 41 inserted into the insertion hole. For example, the fixing member can be a positioning pin, which is simultaneously passed through the base plate 2 and the rotating member 44 to lock the circumferential position of the rotating member 44.

[0052] As a possible example, in this embodiment, the fixed member is a combination lock 45. The combination lock 45 has a rotating shaft that is fixedly connected to the rotating member 44. When the correct password is entered, the rotating shaft rotates. When an incorrect password is entered, the rotating shaft cannot rotate. By using the combination lock 45 to control the circumferential position of the rotating member 44, the daughter board 3 can be prevented from being stolen.

[0053] As a possible example, in this embodiment, the base plate 2 includes a plate body 22 and a cover 23. The cover 23 is removably fixed to one end of the plate body 22. The cover 23 is provided with a mounting hole for a combination lock 45, to which the combination lock 45 is fixed. The portion of the combination lock 45 for entering a password is located outside the cover 23. The connection between the combination lock 45 and the rotating member 44, as well as the rotating member 44, are located inside the cover 23 to prevent the connection between the combination lock 45 and the rotating member 44 from being damaged.

[0054] As a possible example, in this embodiment, after the relative positions of the sub-board 3 and the base plate 2 are locked, the sub-board 3 and the base plate 2 are detachably fixedly connected by the second fastener 32, thereby strengthening the locking effect of the sub-board 3 and the base plate 2 and preventing the sub-board 3 from loosening.

[0055] As a possible example, in this embodiment, the sub-plate 3 is connected to the basket via fasteners. Depending on actual needs, those skilled in the art may also make the sub-plate 3 a part of the basket, for example, making the sub-plate 3 the lower cover of the basket. Alternatively, those skilled in the art may connect the edge of the sub-plate 3 to the upper edge of the basket's sidewall, thereby allowing the basket to be suspended to the side of the loading platform.

[0056] There are many ways to arrange the tripod 1, and those skilled in the art can flexibly choose. For example, Figures 1 to 5In a representative example, there are four tripods 1, which are used to support the four corners of the base plate 2. For another example, Figures 10 to 12 In a representative example, there are two tripods 1 , which are used to support two side edges of the base plate 2 respectively.

[0057] Specifically, Figures 10 to 12 In a representative example, the tripod 1 includes an upper clamping plate 11, a lower clamping plate 12, and a locking bolt 13. The upper clamping plate 11 and the lower clamping plate 12 contact the loading platform from the upper and lower sides, respectively. The locking bolt 13 then passes through the upper clamping plate 11 and is threadedly connected to the threaded hole in the lower clamping plate 12. The upper clamping plate 11 and the lower clamping plate 12 clamp the loading platform from the upper and lower sides, respectively, to secure the tripod 1 to the loading platform.

[0058] As a possible example, in this embodiment, a chamfer 33 is provided on the lower edge of the sub-board 3. The chamfer 33 can be a right-angle chamfer, or another type of chamfer, such as a circular chamfer. The chamfer 33 is provided on at least one side of the sub-board 3 near the locking pin 41, so that when the sub-board 3 slides on the base plate 2 and approaches the locking pin 41, the sliding contact between the chamfer 33 and the upper end of the locking pin 41 presses down the locking pin 41, which extends from the upper surface of the base plate 2, so that the locking pin 41 can better avoid the sub-board 3. When the sub-board 3 slides until the socket provided on its bottom is aligned with the locking pin 41, the locking pin 41 re-extends from the upper surface of the base plate 2 under the elastic force of the spring 42 and automatically inserts into the socket.

[0059] As a possible example, in this embodiment, the base plate 2 further includes a support block 25 slidably mounted on the lower surface of the plate body 22. The support block 25 is threadedly connected to a screw 26. A locking pin 41 is a downwardly opening cylindrical structure. A spring 42 is disposed within the locking pin 41. The upper end of the support block 25 extends into the locking pin 41. The upper end of the spring 42 abuts the bottom of the locking pin 41, while the lower end of the spring 42 abuts the support block 25. The position of the support block 25 can be changed by rotating the screw 26.

[0060] This embodiment also provides a vehicle comprising a frame having a loading platform. The vehicle also includes the aforementioned quick-installation rack system, with multiple tripods 1 secured to the loading platform. Because the vehicle includes the aforementioned quick-installation rack system, it also possesses the aforementioned advantages of the quick-installation rack system, which will not be further elaborated here.

[0061] The present invention uses specific examples to illustrate the principles and implementation methods of the present invention. The above examples are only intended to help understand the method and core concept of the present invention. At the same time, those skilled in the art will find that the specific implementation methods and application scopes may vary based on the concept of the present invention. In summary, the contents of this specification should not be construed as limiting the present invention.
