DETAILED DESCRIPTION

[0040] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0041] Reference Figure 1 to Figure 15 This embodiment provides a shelf quick assembly system, including a stand 1, a bottom 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 frame. The fixing method of the tripod 1 can be flexibly selected, such as fixing by screws, fixing by 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 for carrying 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 mounting hole 21 is adjustable, so 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-board 3 is slidably mounted on the bottom plate 2, and the locking device 4 is used to limit the relative sliding of the sub-board 3 and the bottom plate 2. Specifically, guide grooves 24 are provided on both side edges of the bottom plate 2, and hook-shaped sliding portions 31 are provided on both side edges of the sub-board 3, and the ends of the sliding portions 31 extend into the guide grooves 24 and slide along the guide grooves 24. It can be understood that those skilled in the art can also set the guide grooves 24 on the sub-board 3 and the sliding portions 31 on the bottom plate 2, as long as the sub-board 3 and the bottom plate 2 can slide relative to each other.

[0046] There are many types of locking device 4, and those skilled in the art can select according to actual needs. For example, locking device 4 is a locking screw, which passes through sub-board 3 and is threadedly connected to bottom board 2 to achieve locking of the relative position of sub-board 3 and bottom board 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 plug hole 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 plug hole, 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 to extend out of the through hole through the shifting mechanism, so that one end of the locking pin 41 is inserted into the plug hole. 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 shifting mechanism includes a spring 42 and a slider 43, and the spring 42 is located between the locking pin 41 and the base plate 2. One end of the spring 42 is connected to the locking pin 41, and the other end of the spring 42 is connected to the base plate 2. The slider 43 is slidably mounted on the base plate 2, and an inclined profile 431 is provided on the slider 43, and the inclined profile 431 can be a plane or a curved surface. The locking pin 41 is provided with a protrusion 411 for sliding contact with the inclined profile 431. When the slider 43 slides along a first direction, the inclined profile 431 presses the locking pin 41 against the spring 42, causing the spring 42 to contract and the locking pin 41 to be retracted into the through hole. When the slider 43 slides along a second direction, the spring 42 pushes the locking 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 methods.

[0050] As a possible example, in this embodiment, the shift mechanism further includes a rotating member 44, which is rotatably mounted on the bottom plate 2. A lever 441 is eccentrically arranged on the rotating member 44, and a slide groove 432 is arranged on the slider 43, and the lever 441 extends into the slide groove 432. When the rotating member 44 rotates, the lever 441 slides along the slide groove 432 while rotating. The lever 441 pushes the side wall of the slide groove 432, so that the slider 43 slides on the bottom plate 2. Through the above-mentioned connection structure, this embodiment converts the rotational motion of the rotating member 44 into the 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 on the bottom plate 2 so that the rotating member 44 cannot rotate, thereby keeping the locking pin 41 inserted into the insertion hole. For example, the fixing member can be a positioning pin, and the circumferential position of the rotating member 44 is locked by passing the positioning pin through the bottom plate 2 and the rotating member 44 at the same time.

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

[0053] As a possible example, in this embodiment, the bottom plate 2 includes a plate body 22 and a cover 23, and the cover 23 is detachably fixed to one end of the plate body 22. The cover 23 is provided with a mounting hole for a password lock 45, and the password lock 45 is fixed at the mounting hole for the password lock 45. The portion of the password lock 45 for inputting a password is located outside the cover 23, and the connection portion between the password lock 45 and the rotating member 44 and the rotating member 44 are located inside the cover 23 to prevent the connection portion between the password 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-board 3 is used to connect with the basket through fasteners. According to different actual needs, those skilled in the art may also make the sub-board 3 a part of the basket, for example, make the sub-board 3 the lower cover of the basket. Alternatively, those skilled in the art may also connect the edge of the sub-board 3 with the upper edge of the side wall of the basket, so that the basket is suspended on 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, Figure 1 to Figure 5 In a representative example, there are four tripods 1, and the four tripods 1 are used to support the four corners of the base plate 2 respectively. Figure 10 to Figure 12 In a representative example, there are two tripods 1 , and the two tripods 1 are respectively used to support two side edges of the base plate 2 .

[0057] Specifically, Figure 10 to Figure 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 stage from the upper and lower sides respectively, and then the locking bolt 13 passes through the upper clamping plate 11 and is threadedly connected with the threaded hole on the lower clamping plate 12, so that the upper clamping plate 11 and the lower clamping plate 12 clamp the stage from the upper and lower sides respectively, thereby fixing the tripod 1 on the stage.

[0058] As a possible example, in this embodiment, a chamfer 33 is provided on the lower edge of the sub-board 3, and the chamfer 33 may be a right-angle chamfer or other types such as a circular chamfer. The chamfer 33 is provided at least on one side of the sub-board 3 close to the locking pin 41, so that when the sub-board 3 slides on the bottom plate 2 close to the locking pin 41, the chamfer 33 and the upper end of the locking pin 41 are in sliding contact, and the locking pin 41, whose upper end extends out of the upper surface of the bottom plate 2, is pressed down, so that the locking pin 41 can better avoid the sub-board 3. When the sub-board 3 slides to the insertion hole provided at its bottom and faces the locking pin 41, the locking pin 41 is extended from the upper surface of the bottom plate 2 again under the elastic force of the spring 42 and automatically inserted into the insertion hole.

[0059] As a possible example, in this embodiment, the bottom plate 2 further includes a support block 25 slidably disposed on the lower surface of the plate body 22, and the support block 25 is threadedly connected to the screw rod 26. The lock pin 41 is a cylindrical structure with an opening facing downward, the spring 42 is disposed in the lock pin 41, and the upper end of the support block 25 extends into the lock pin 41. The upper end of the spring 42 abuts against the bottom of the cylinder of the lock pin 41, and the lower end of the spring 42 abuts against the support block 25. By rotating the screw rod 26, the position of the support block 25 can be changed.

[0060] This embodiment also provides a carrier, including a frame, the frame having a loading platform. The carrier also includes the above-mentioned shelf quick installation system, and multiple tripods 1 are fixed on the loading platform. Since the carrier includes the above-mentioned shelf quick installation system, it also has the above-mentioned advantages of the shelf quick installation system, which will not be repeated here.

[0061] The present invention uses specific examples to illustrate the principle and implementation of the present invention. The above examples are only used to help understand the method and core idea of ​​the present invention. At the same time, for those skilled in the art, according to the idea of ​​the present invention, there will be changes in the specific implementation and application scope. In summary, the content of this specification should not be understood as limiting the present invention.
