Description

Technical Field

[0001] The utility model relates to the technical field of pallet equipment, and particularly relates to an adjustable pallet. Background Technique

[0002] A pallet is an important logistics equipment. It can transform static goods into dynamic goods, improve logistics efficiency and reduce costs. In the prior art, since there are no pulleys at the bottom of the pallet, the movement of the pallet is relatively laborious and requires manual or equipment handling. For some pallets with pulleys, the pulleys are squeezed for a long time, resulting in easy damage of the pulleys. There is no function of storing the pulleys. At the same time, when small goods are placed on the pallet, the goods are prone to move and misalign. The pallet lacks the function of being compatible with both large and small goods.

[0003] For example, a forklift pallet disclosed in the authorized patent document with the application number CN202021769453.8 includes: a pallet body, a first support beam protruding from the pallet body, two second support beams, a reinforcing strip installed between the first support beam and the second support beams, a first fluorescent sticker installed at the end of the first support beam, and a second fluorescent sticker installed on the side of the second support beam. Two second support beams and the first support beam form two first insertion channels. The pallet body is provided with a plurality of weight reduction holes, and the weight reduction holes are communicated with the first insertion channels. The first support beam is provided with two first through holes, and the second support beam is provided with two second through holes arranged opposite to the first through holes. Two second insertion channels are formed between the second through holes and the first through holes. The structural layout of the forklift pallet is reasonable, with many channels, which is convenient for the forklift to accurately position and improves the handling efficiency.

[0004] The above-mentioned patent is a pallet with pulleys. The pulleys are squeezed for a long time, resulting in easy damage of the pulleys. There is no function of storing the pulleys. Therefore, we need to provide an adjustable pallet. Content of the Utility Model

[0005] The purpose of the present utility model is to provide an adjustable tray. Large or small goods are placed on the pallet, the distance between two limit angle seats is adjusted, and installation bolts pass through the limit angle seats and are threadedly installed with the hole parts to limit the large or small goods on the pallet. At the same time, when the goods are placed on the pallet, the weight of the goods is transmitted to the pallet, the pallet presses four springs, and drives four guide rods to slide in the bottom plate. As the pallet moves downward, it drives four adjusting frames to rotate, thereby pulling four pull rods. The pull rods move upward to store the pulleys inside the support seats, so that the bottom of the support seats contacts the ground for support, and the pulleys are retracted. The bottom of the pallet will contact the support bars, and the support bars play an auxiliary supporting effect on the pallet, avoiding the weight of the goods being transmitted to the pulleys and reducing the service life of the pulleys. When the goods are taken away from the pallet, under the action of the springs, the pallet moves upward, the four pulleys pop out, and the bottom plate is supported, making the movement of the bottom plate smoother, and solving the problems raised in the above-mentioned background technology.

[0006] To achieve the above object, the present utility model provides the following technical solutions: an adjustable tray, comprising: a bottom plate; and a pallet disposed on the top of the bottom plate; a limiting member installed on the top of the pallet for placing large and small goods; an adjusting member installed on the top of the bottom plate for retracting the pulleys;

One end of the adjusting frame 42 is hinged with a pull rod 43. The lower end of the pull rod 43 penetrates through the bottom of the bottom plate 1 and is hinged with a floating plate 44. A pulley 45 is rotatably installed at the bottom of the floating plate 44. Two mounting seats 46 are hinged inside the two adjusting frames 42. A frame 47 is fixedly installed on the top of the two mounting seats 46. The frame 47 is fixedly installed on the top of the bottom plate 1.

[0025] Four guide rods 5 are movably sleeved inside the four springs 41. The tops of the four guide rods 5 are fixedly installed at the bottom of the tray 2, and the surfaces of the four guide rods 5 are slidably installed inside the bottom plate 1;

[0026] In this embodiment, large or small goods are placed on the tray 2. The distance between the two limiting angle seats 31 is adjusted, and the mounting bolts 32 penetrate through the limiting angle seats 31 and are threadedly installed with the hole parts 33 to limit the large or small goods on the tray 2. At the same time, when the goods are placed on the tray 2, the weight of the goods is transmitted to the tray 2. The tray 2 presses the four springs 41 and drives the four guide rods 5 to slide inside the bottom plate 1. As the tray 2 moves downward, it drives the four adjusting frames 42 to rotate, thereby pulling the four pull rods 43. The pull rods 43 move upward to receive the pulley 45 into the support seat 8, so that the bottom of the support seat 8 contacts the ground for support, retracting the pulley 45. The bottom of the tray 2 will contact the support strip 12, and the support strip 12 provides an auxiliary support effect on the tray 2 to prevent the weight of the goods from being transmitted to the pulley 45, reducing the service life of the pulley 45. When the goods are taken away from the tray 2, under the action of the spring 41, the tray 2 moves upward, the four pulleys 45 pop out, and the bottom plate 1 is supported, making the movement of the bottom plate 1 smoother.

[0027] A reserved groove 6 for the movement of the pull rod 43 is provided inside the adjusting frame 42;

[0028] Among them, a reserved groove 6 for the movement of the pull rod 43 is provided inside the adjusting frame 42, which is sufficient to realize the swing of the pull rod 43 and smoothly drive the pulley 45 to move.

[0029] Two shielding plates 7 are fixedly installed inside the two frames 47, and the bottoms of the two shielding plates 7 are attached to the top of the tray 2;

[0030] Furthermore, when the spring 41 pushes the tray 2 out, the top of the tray 2 is attached to the bottom of the shielding plate 7, thereby limiting the tray 2.

[0031] The limiting member 3 includes two limiting angle seats 31 arranged on the top of the pallet 2. Two mounting bolts 32 are movably sleeved inside the two limiting angle seats 31, and a hole portion 33 for threaded mounting of the two mounting bolts 32 is formed inside the pallet 2.

[0032] It should be noted that when placing large or small goods on the pallet 2, adjust the distance between the two limiting angle seats 31, and thread-mount the mounting bolts 32 through the limiting angle seats 31 and the hole portion 33 to limit the large or small goods on the pallet 2.

[0034] It is worth noting that four support seats 8 are arranged at the bottom of the bottom plate 1. When goods are placed on the pallet 2, the bottom of the support seats 8 contacts the ground to support the bottom plate 1 and at the same time store and protect the pulleys 45.

[0035] Reinforcing strips 9 are fixedly installed at the bottom of the bottom plate 1, and placing grooves 10 for attaching label codes are embedded in the front and back of the reinforcing strips 9.

[0036] The reinforcing strips 9 are provided to support the bottom plate 1. At the same time, placing grooves 10 for attaching label codes are formed on the front and back of the reinforcing strips 9, which is convenient for marking the goods.

[0037] Protective strips 11 are installed at the four corners of the bottom plate 1, and a number of support strips 12 are fixedly installed at the top of the bottom plate 1.

[0038] Among them, the protective strips 11 are arranged at the four corners of the bottom plate 1 to provide anti-collision protection for the bottom plate 1. At the same time, the bottom of the pallet 2 will contact the support strips 12, and the support strips 12 provide auxiliary support for the pallet 2.

[0039] This device places large or small goods on the pallet 2, adjusts the distance between the two limit angle seats 31, and is threadedly installed through the limit angle seat 31 and the hole part 33 by the mounting bolt 32, which has a limiting effect on the large or small goods on the pallet 2. At the same time, when the goods are placed on the pallet 2, the weight of the goods is transmitted to the pallet 2, the pallet 2 presses the four springs 41, and drives the four guide rods 5 to slide in the bottom plate 1. As the pallet 2 moves downward, it drives the four adjusting frames 42 to rotate, thereby pulling the four pull rods 43. The pull rods 43 move upward to receive the pulleys 45 into the support seat 8, so that the bottom of the support seat 8 contacts the ground for support, and the pulleys 45 are retracted. The bottom of the pallet 2 will contact the support bar 12, and the support bar 12 has an auxiliary support effect on the pallet 2, avoiding the weight of the goods being transmitted to the pulleys 45 and reducing the service life of the pulleys 45. When the goods are taken away from the pallet 2, under the action of the springs 41, the pallet 2 moves upward, the four pulleys 45 pop out, and the bottom plate 1 is supported, making the movement of the bottom plate 1 smoother.
