Wherein the pull rod 102 is a U-shaped structure.

As shown in fig. 3, the tray body includes a top plate 301 and pedestals 302 removably secured, with the noted carrying gaps formed between adjacent pedestals 302. The top plate and the base can be fixed in various ways, and can be fixed in non-detachable fixing ways such as welding and the like, and can also be fixed in a threaded, clamping or suction manner. For example, the common fixing method can adopt a thread fixing method (fixing the two by using a screw), a magnet attracting method and the like. In this embodiment, the top plate 301 and the base 302 are fixed by screws.

In this embodiment, there are 9 bases 302, and the bases 302 are connected together by the reinforcing plate 303. The base 302, the reinforcing plate 303 and the top plate 301 are all plastic parts. The base and the reinforcing plate are of an integral structure and are directly processed and molded during processing. Can be processed by injection molding or blow molding. Of course, the base can be arranged independently, i.e. no reinforcing plate is arranged between the base and the base. Or several bases in a row are connected into a whole through a reinforcing plate.

A cavity structure is arranged in the top plate, and the positioning pipe is arranged in the cavity. By adopting the technical scheme, on one hand, the compactness and the attractiveness of the whole structure are improved, and meanwhile, the pull rod structure is protected. In this embodiment, the top plate is manufactured by a blow molding process, and the base communication reinforcing plate is processed by an injection molding process.

Referring to fig. 4, 5 and 6, a specific structure of the pull rod and its related installation components is that a positioning tube 401 is fixed in the pull rod receiving space, a limit block 402 is slidably arranged in the positioning tube, and one side of the limit block is hinged and fixed with the end of the pull rod 102. Through the registration arm, simple installation and the accomodating of having realized the pull rod. The end of the pull rod is provided with a hinge joint 403; a hinged seat 404 is slidably arranged in the positioning tube, one end of the hinged seat is a hinged end hinged with the hinged joint, and the other end of the hinged seat is provided with the limit block 402.

As an implementation scheme, the hinge joint comprises a mounting seat 501 with threaded holes at two ends and a hinge lug 502 fixed with the threaded hole at one end for being hinged with the hinge joint 403 of the pull rod, and a screw rod matched with the threaded hole at the other end of the mounting seat is arranged on the limiting block 402. The limiting block 402, the mounting seat 501 and the hinge lug 502 are fixed to each other sequentially in a threaded manner.

A positioning seat 503 and a limiting guide cylinder 504 which is fixed opposite to the positioning seat 503 and through which the pull rod passes are fixed on one side of the tray body. The positioning seat 503 is a U-shaped plate structure, and two mounting side plates of the U-shaped plate structure are fixed to the tray body by screws and the like. The positioning seat 503 and the limiting guide cylinder 504 may be welded, or may be fixed by other threads or may be an integral structure. One end of the limiting guide cylinder 504 is fixed relative to the positioning seat 503, and the other end is inserted into the positioning tube 401. The locating tube 401 side pipe, the stopper be with the square board of locating tube complex, the guide cylinder 504 terminal surface be circular terminal surface, the diameter is less than the width of limiting plate, can restrict the stopper in the locating tube. The setting of spacing guide cylinder has realized the direction to the pull rod on the one hand, guarantees that the pull rod pulls out smoothly, and spacing guide cylinder has still acted as the effect of above-mentioned spacing protruding simultaneously, right the stopper plays limiting displacement, prevents that the pull rod from being pulled out. According to the invention, the arrangement of the positioning seat realizes the installation and positioning of the positioning pipe and the limiting of the pull rod.

The limiting guide cylinder 504 is also provided with a positioning hole 505, and the pull rod is provided with a positioning bead 506 which limits the pull rod in the accommodating state when matched with the positioning hole. In the technical scheme, the positioning holes can be also arranged on other parts, and the positioning of the positioning beads can be realized. The setting of location pearl for when the pull rod does not use, can fix the pull rod in the pull rod storage space in the disk body avoids the automatic roll-off of pull rod. When the pull rod is needed to be used, the positioning balls can be separated from the positioning holes by applying a small force, and the pull rod can move freely at the moment.

In the invention, the tray body can be a plastic piece or a metal piece, and when the plastic piece is selected, the tray body can be subjected to one-time injection molding or blow molding during processing, namely, the integral structure or the split structure can be selected.

Referring to fig. 3, the bottom surface of the base forms a recessed area that can be used to mount casters 304. By adopting the technical scheme, the installation position of the caster is not required to be additionally arranged, and meanwhile, most of the volume of the caster is positioned in the concave area, so that the volume of the whole structure is reduced, and the whole structure is more compact. Of course, in the technical solution of the present invention, it is not necessary to provide casters on all of the bottom surfaces of the base, and at least three casters are generally provided as long as the stability of the entire tray can be ensured. In this embodiment, each base bottom surface is provided with a caster 304.

Alternatively, a hinge seat is arranged in the concave area, the caster wheel is connected in a caster seat, and the caster seat is hinged in the hinge seat; the caster wheel has a storage state of being stored in the concave area and a working state of being vertically arranged with the top plate after being turned over. And a locking piece for positioning the caster in the working state or the storage state is arranged between the hinged seat and the caster seat. The locking piece is equipped with at least one locating lever including sliding the slide that sets up in the depressed area on this slide, be equipped with on the articulated seat with the locking hole that the locating lever was adjusted well, be equipped with two at least locking holes on the truckle seat when the truckle is in storage state or operating condition, at least one locking hole with the locating hole is adjusted well.

As shown in fig. 1, 5, and 6, when the pull rod is not needed, the pull rod 102 is received in the positioning tube 401 by the positioning ball 506.

As shown in fig. 2, 7 and 8, when the pull rod is needed, a horizontal pulling force can be applied to the pull rod 102 to make the positioning bead come out of the positioning hole 505, and the pulling force is continuously applied until the whole pull rod extends out of the positioning tube 401, at this time, the pull rod is not limited by the positioning tube, and under the action of the hinge base 404, the pull rod can be turned over up and down to meet the actual requirement.

Referring to fig. 12 and 13, the invention is a basic technical solution, which comprises a tray body 101 provided with a conveying gap, one or more layers of supporting partitions 1201 arranged on the top surface of the tray body 101, and a connecting column 1202 for connecting the layers of supporting partitions in sequence or connecting the supporting partitions and the tray body through a detachable structure.
