Description

Technical Field

[0001] The utility model relates to the field of logistics shelf auxiliary components, in particular to a logistics shelf with adjustable layer board spacing. Background Art

[0002] The important role of logistics in regional economic development is increasingly recognized by people. Many regions have included the development of modern logistics in their important agenda. Logistics modernization and economic development are closely related. In the process of logistics operations, logistics shelves are commonly used storage tools in logistics warehousing. Due to the special structure, they can usually accommodate many cargo packages at the same time, which greatly achieves the purpose of classification management and reduces the space occupied by cargo packages.

[0003] In the specific design of existing logistics racks, multiple layers of storage boards are usually provided for placing cargo packages. The multiple layers of storage boards are usually evenly stacked in the vertical direction to improve the utilization rate of the vertical space. However, since the multiple layers of storage boards are usually installed and set by riveting or screwing, the layer spacing between adjacent storage boards is fixed and cannot be adjusted. Therefore, only cargo packages with a certain height size range can be stored. In the process of placing and using cargo packages, when the vertical size specifications of the cargo packages exceed the layer spacing between adjacent storage boards, the cargo packages will not be able to be smoothly and neatly placed, resulting in poor versatility of the logistics rack. At the same time, since the board area of ​​the storage board is fixed and cannot be adjusted, when the cargo packages placed on the storage board obviously exceed the front and rear edges of the board surface, the placement will be unstable, resulting in the risk of the cargo packages falling and being damaged.

Specifically in operation, since the movable tooth plate of the locking block and the fixed tooth plate in the adjusting groove are meshed with each other at the beginning, the The meshing manner of the movable tooth plate and the fixed tooth plate can prevent the storage plate from changing its position in the vertical direction, so that the position height of the storage layer plate assembly is locked at this time. When the vertical position height of the storage layer plate assembly is adjusted, the clamping nuts at both sides are first loosened to leave them from the surface of the shelf side plate, and then two people simultaneously hold the handles at both sides and pull them outward, and the movable tooth plate of the locking block is separated from the fixed tooth plate of the adjusting groove by the compression of the spring, and then the locking block is driven to slide vertically along the adjusting groove by keeping the handle pulled outward, and the storage plate is immediately raised and lowered in the vertical direction to adjust the position height. When the storage plate is at a high position, When the height is adjusted to the right, the storage plate is kept stationary and the handle is released, and the spring immediately releases the compressed state to drive the locking block to return to its original position, so that the movable tooth plate is meshed with the fixed tooth plate again, thereby completing the locking of the vertical position height of the storage plate again. In this way, the locking block can slide vertically along the adjustment slot and the movable tooth plate of the locking block and the fixed tooth plate of the adjustment slot can be meshed with each other laterally to quickly adjust the vertical position height of the storage layer plate assembly and lock it. The adjustment method of the vertical position height of the storage layer plate assembly is simple and easy to operate, which makes it easy to quickly adjust the layer spacing between adjacent storage layer plate assemblies. At the same time, when the safety guide assembly is loosened, The lock member can be easily unlocked by pulling the connecting rod outward to release the locking state of the vertical position height of the storage shelf assembly after the compression nut is tightened. The locking state of the vertical position height of the storage shelf assembly can be released by pulling the connecting rod outward to separate the movable tooth plate of the locking block and the fixed tooth plate of the adjusting groove.

It should be noted that when the storage shelf assembly is detached from the shelf side panels at both sides, the storage shelf assembly should be detached in sequence from top to bottom. Specifically, in the use of the storage shelf assembly, since the storage shelf assembly has the function of expanding the storage area, when the placed cargo packages exceed the front and rear edges of the storage board surface, the locking screw is loosened, and then the distance between the extension plate and the storage board is expanded and adjusted by sliding the slide plate longitudinally along the sliding groove and tightening the locking screw to press against the bottom surface of the slide plate at the end of the sliding. Then, the storage area at the top of the storage shelf assembly can be expanded. Therefore, when the cargo packages placed on the storage board exceed the front and rear edges of the storage board surface, the storage area can be expanded by expanding the storage shelf assembly to improve the placement stability of the placed cargo packages, thereby avoiding the risk of cargo packages falling and being damaged.

[0019] The beneficial effects are as follows: 1. The utility model can adjust and lock the vertical position height of each layer of the storage layer assembly through the layer spacing adjustment assembly, so that the layer spacing between adjacent storage layer assemblies can be expanded or contracted, which is convenient for adaptively adjusting the layer spacing between adjacent storage layer assemblies according to the vertical size of the placed cargo packages, ensuring that the cargo packages can be smoothly and neatly placed, while improving the use flexibility of the storage layer assembly;

[0020] 2. The vertical position height of the storage layer plate assembly can be quickly adjusted and locked by sliding the locking block vertically along the adjustment groove and engaging the movable tooth plate of the locking block and the fixed tooth plate of the adjustment groove laterally close to each other. The vertical position height adjustment method of the storage layer plate assembly is simple and easy to operate, and the interlayer spacing between adjacent storage layer plate assemblies can be quickly adjusted.

[0021] 3. The guide stud of the safety guide assembly slides vertically along the guide groove to guide the vertical lifting and lowering adjustment process of the storage layer assembly, which is conducive to the storage layer assembly to smoothly complete the vertical position height adjustment process. At the same time, after the vertical position height of the storage layer assembly is adjusted and locked, the compression nut of the safety guide assembly is tightened on the surface of the shelf side plate to perform another safety lock when the height adjustment of the storage layer assembly is completed, which is conducive to improving the stability of the storage layer assembly during the use of placing regular cargo packages;

[0022] 4. After loosening the compression nut of the safety guide assembly, the locking state of the vertical position height of the storage layer assembly can be released by simply pulling the connecting rod outward to separate the movable tooth plate of the locking block and the fixed tooth plate of the adjustment groove from each other. The unlocking method of the vertical position height of the storage layer assembly is simple and easy to operate, which further facilitates the rapid adjustment of the layer spacing between adjacent storage layer assemblies.

[0023] 5. The top ends of the guide grooves of the safety guide assembly and the adjustment grooves of the layer spacing adjustment assembly are both openly arranged, and then the storage layer assembly can be quickly detached from the top of the shelf side panel by sliding the guide studs and the locking blocks vertically upward and respectively disengaging from the guide grooves and the adjustment grooves. The separation method of the storage layer assembly between the two side shelf side panels is simple and easy to operate, and then the storage layer assembly can be quickly detached for regular maintenance. At the same time, it is convenient to flexibly combine and set the number of storage layer assemblies, which is conducive to further improving the flexibility of the use of the storage layer assembly;

The distance between the extension plate and the storage plate can be expanded and adjusted by sliding the slide plate longitudinally along the sliding groove and tightening the locking screws to press it against the bottom surface of the slide plate. Then, the storage area on the top of the storage shelf assembly can be expanded. When the cargo packages placed on the storage board exceed the front and rear edges of the storage board, the storage area can be expanded by using the storage shelf assembly to improve the placement stability of the cargo packages, thereby avoiding the risk of the cargo packages falling and being damaged.

At the same time, the advantage of using the above-mentioned storage layer assembly 1 is that, since the storage layer assembly 1 has a storage area As for the expansion function, the distance between the extension plate 101 and the storage plate 102 can be expanded and adjusted by sliding the slide plate 106 longitudinally along the sliding groove 105 and tightening the locking screws 108 to press the slide plate 106 against the bottom surface, and then the storage area on the top of the storage layer assembly 1 can be expanded. When the cargo packages placed on the storage plate 102 exceed the front and rear edges of the storage plate 102, the storage area can be expanded by expanding the storage layer assembly 1 to improve the placement stability of the cargo packages.

[0044] See also Figure 1-Figure 4As shown, the front and rear positions on both sides of the storage layer board assembly 1 are installed with layer distance adjustment components 5, and the layer distance adjustment components 5 are partially arranged on the inner surface of the shelf side panels 3, and the storage layer board assembly 1 is detachably fixed between the shelf side panels 3 at both sides through the layer distance adjustment components 5, so as to adjust the vertical position height of the storage layer board assembly 1 through the layer distance adjustment components 5, so as to expand or shrink the layer distance between adjacent storage layer board assemblies 1. Specifically, the layer distance adjustment component 5 includes an adjustment groove 502 and a mounting plate 504, and the end surfaces of the shelf side panels 3 at both sides are opposite to each other. Adjustment slots 502 are vertically opened at the front and rear positions, and the outer end surfaces of the adjustment slots 502 at the two side positions facing each other are open, and the inner end surfaces of the adjustment slots 502 at the two side positions facing each other are covered and fixed with fixed tooth plates 506 with longitudinal teeth, and the four corners of the bottom surface of the storage plate 102 are all vertically extended and fixed with mounting plates 504 in the longitudinal direction, and the mounting plates 504 are interspersed with connecting rods 507 in a transverse sliding fit manner, and the inner ends of the connecting rods 507 at the two side positions close to each other are coaxially fixed with handles 505, and the outer ends of the connecting rods 507 at the two side positions away from each other are fixed with locking blocks 501, and the locking blocks 501 corresponds to the adjustment slot 502 one by one and is slidably matched vertically. The outer end surfaces of the locking blocks 501 at the two sides that are away from each other are covered and fixed with movable tooth plates 508, and the movable tooth plates 508 are meshed with the adjacent fixed tooth plates 506. The part of the connecting rod 507 located between the corresponding locking block 501 and the mounting plate 504 is coaxially gap-matched with a spring 503, and both ends of the spring 503 are fixedly connected to the corresponding locking block 501 and the mounting plate 504. The purpose of this arrangement is that in the process of adjusting the position height of the storage layer plate assembly 1 through the layer spacing adjustment assembly 5, the locking block 501 By sliding vertically along the adjustment groove 502 and engaging with the movable tooth plate 508 of the locking block 501 and the fixed tooth plate 506 of the adjustment groove 502 when they are laterally approached to each other, the vertical position height of the storage layer plate assembly 1 can be quickly adjusted and locked, thereby facilitating the rapid adjustment of the layer spacing between adjacent storage layer plate assemblies 1. After loosening the clamping nut 202 of the safety guide assembly 2, it is only necessary to pull the connecting rod 507 outward to separate the movable tooth plate 508 of the locking block 501 and the fixed tooth plate 506 of the adjustment groove 502 from each other to release the locked state of the vertical position height of the storage layer plate assembly 1.

[0045] See also Figure 1 , Figure 2 , Figure 8 , Fig. 9 and Fig.10As shown, safety guide components 2 for guiding and locking the vertical adjustment of the storage layer assembly 1 are installed at both sides of the storage layer assembly 1, and the safety guide components 2 are partially arranged on the adjacent shelf side panels 3, and the storage layer assembly 1 is also detachably fixed between the shelf side panels 3 at both sides through the safety guide components 2. Specifically, the safety guide components 2 include guide grooves 203 and guide studs 204, and the middle parts of the shelf side panels 3 at both sides are vertically opened with guide grooves 203 in the horizontal direction, and the guide grooves 203 are through grooves in the horizontal direction, and the middle parts of both sides of the storage plate 102 are fixed with guide studs 204 in the horizontal direction, and the guide studs 204 pass through the adjacent guide grooves 203 in a horizontal sliding fit manner. The portion of the guide stud 204 extending out of the corresponding guide groove 203 is coaxially engaged with a clamping nut 202. Such a configuration facilitates the vertical lifting and lowering adjustment process of the storage shelf assembly 1 to be guided by the guide stud 204 of the safety guide assembly 2 sliding vertically along the guide groove 203, which is beneficial for the storage shelf assembly 1 to smoothly complete the vertical position height adjustment process. At the same time, after the vertical position height of the storage shelf assembly 1 is adjusted and locked, the clamping nut 202 of the safety guide assembly 2 is tightened on the surface of the shelf side panel 3 to perform another safety lock when the position height adjustment of the storage shelf assembly 1 is completed, which is beneficial for improving the stability of the storage shelf assembly 1 during the use of placing regular cargo packages.

[0046] See also Figure 1-Figure 5 As shown, the storage layer plate assembly 1 is optimized as follows. First, the front end surface of the storage plate 102 is provided with a plurality of guide holes 103 along the longitudinal direction at both sides of the sliding groove 105, and the guide holes 103 are all through holes in the longitudinal direction. The extension plates 101 at the front and rear positions are fixed with a plurality of guide rods 104 along the longitudinal direction at both sides of the end surface close to the storage plate 102. The guide rods 104 correspond to the guide holes 103 one by one and extend into the corresponding guide holes 103 in a longitudinal sliding manner. The purpose of such a setting is that, first, in the process of the sliding plate 106 sliding along the sliding groove 105, the sliding of the sliding plate 106 can be guided and corrected by the guide rods 104 sliding longitudinally along the guide holes 103. At the same time, by arranging a plurality of guide rods 104 between the storage plate 102 and the extension plate 101, the guide rods 104 can also be used to block the position between the storage plate 102 and the extension plate 101, which is beneficial to improving the stability of the extension plate 101 after expansion.

[0047] At the same time, the cross-sectional shapes of the sliding groove 105 and the sliding plate 106 along the horizontal vertical plane are both rectangular, and the cross-sectional shapes of the guide hole 103 and the guide rod 104 along the horizontal vertical plane are both circular. And further optionally, the end faces of the extension plate 101 and the storage plate 102 close to each other are in contact with each other, and the ends of the sliding plates 106 close to each other at the front and rear positions are in contact with each other, and the ends of the guide rods 104 close to each other at the front and rear positions are in contact with each other. Such a setting first facilitates the sliding groove 105 to have a good positioning and guiding design when the sliding plate 106 slides longitudinally along the sliding groove 105, and at the same time facilitates when the end faces of the extension plate 101 and the storage plate 102 contact each other, it can be clearly prompted by the close contact of the ends of the sliding plates 106 close to each other at the front and rear positions and the close contact of the ends of the guide rods 104 close to each other at the front and rear positions.

[0048] See also Figure 1-Figure 7 As shown, the layer spacing adjustment component 5 is optimized as follows: the top of the adjustment groove 502 is open, and the horizontal cross-sectional shapes of the adjustment groove 502 and the locking block 501 are both rectangular, and the tooth shapes of the fixed tooth plate 506 and the movable tooth plate 508 are both straight teeth. The purpose of this arrangement is, firstly, to facilitate the locking block 501 to slide vertically along the adjustment groove 502, and the adjustment groove 502 has a good positioning and guiding design. At the same time, since the tooth shapes of the fixed tooth plate 506 and the movable tooth plate 508 are both straight teeth, it is ensured that the movable tooth plate 508 can achieve the meshing of the two by approaching the fixed tooth plate 506 laterally.

[0049] At the same time, the springs 503 are in an unstretched state, and the outer peripheries of the handles 505 do not contact the bottom surfaces of the corresponding storage plates 102. With this arrangement, firstly, since the springs 503 are in an unstretched state, the springs 503 are prevented from exerting force to cause the movable tooth plate 508 and the fixed tooth plate 506 to separate from each other. At the same time, since the outer peripheries of the handles 505 do not contact the bottom surfaces of the corresponding storage plates 102, the storage plates 102 can be prevented from interfering with the smooth pulling of the handles 505.

[0050] See also Figure 8-Figure 10As shown, the safety guide assembly 2 is optimized as follows: the adjustment slots 502 are all waist-shaped slots set vertically and open at the top, so that the guide studs 204 can slide out smoothly from the top of the adjustment slots 502, and at the same time, the adjustment slots 502 have a sufficiently wide vertical sliding guide length. Specifically, at the guide studs 204, the clamping nuts 202 are all hand-tightened knurled nuts and the outer diameters are larger than the longitudinal slot width of the guide slots 203. The outer ends of the guide studs 204 at both sides are coaxially fixed with end plates 201. Such a setting makes it easier for the clamping nuts 202 to be tightened or loosened by direct hand tightening. At the same time, the setting of the end plates 201 can also prevent the clamping nuts 202 from detaching from the outer ends of the guide studs 204. Moreover, the setting of the end plates 201 also facilitates the holding and driving of the guide studs 204 to slide vertically along the guide slots 203.

[0051] By adopting the above structure, specifically in the process of neatly placing cargo packages, the vertical position height of the storage layer board assembly 1 of each layer can be raised and lowered and locked through the layer spacing adjustment assembly 5, so that the layer spacing between adjacent storage layer board assemblies 1 can be expanded or contracted, which is convenient for adaptively adjusting the layer spacing between adjacent storage layer board assemblies 1 according to the vertical size of the cargo packages, ensuring that the cargo packages can be smoothly and neatly placed, while improving the use flexibility of the storage layer board assembly 1. Specifically in operation, since the movable tooth plate 508 of the locking block 501 and the fixed tooth plate 506 in the adjustment slot 502 are meshed with each other at the beginning, the movable tooth plate 508 and the fixed tooth plate 506 are meshed with each other at this time. This meshing mode can prevent the storage plate 102 from changing its position in the vertical direction, so that the position height of the storage layer plate assembly 1 is locked at this time. When the vertical position height of the storage layer plate assembly 1 is adjusted, the clamping nuts 202 at the two sides are loosened first to leave them from the surface of the shelf side plate 3. Then, two people hold the handles 505 at the two sides and pull them outward at the same time, and the moving tooth plates 508 of the locking block 501 are separated from the fixed tooth plates 506 of the adjustment groove 502 by the compression of the springs 503. Then, the locking block 501 can be driven to slide vertically along the adjustment groove 502 by keeping the handles 505 pulled outward. The storage plate 102 is then adjusted vertically to adjust its position height. When the position height of the storage plate 102 is adjusted to the right When the handle 505 is released, the spring 503 releases the compressed state and drives the locking block 501 to return to its original position, so that the movable tooth plate 508 is meshed with the fixed tooth plate 506 again, so as to complete the locking of the vertical position height of the storage plate 102 again. In this way, the locking block 501 slides vertically along the adjustment slot 502 and the movable tooth plate 508 of the locking block 501 and the fixed tooth plate 506 of the adjustment slot 502 are meshed with each other horizontally. The vertical position height of the storage layer assembly 1 can be quickly adjusted and locked. The vertical position height adjustment method of the storage layer assembly 1 is simple and easy to operate, which makes it easy to quickly adjust the layer spacing between adjacent storage layer assemblies 1. At the same time, when the safety guide assembly 501 is loosened, the vertical position height of the storage layer assembly 1 can be quickly adjusted. After the compression nut 202 of the component 2 is tightened, it is only necessary to pull the connecting rod 507 outward to separate the movable tooth plate 508 of the locking block 501 and the fixed tooth plate 506 of the adjustment groove 502 from each other to release the locking state of the vertical position height of the storage layer plate assembly 1. The unlocking method of the vertical position height of the storage layer plate assembly 1 is simple and easy to operate, which further facilitates the rapid adjustment of the layer spacing between adjacent storage layer plate assemblies 1. At the same time, during the process of adjusting the vertical position height of the storage layer plate assembly 1, the guide stud 204 of the safety guide assembly 2 can slide vertically along the guide groove 203 to guide the vertical lifting and lowering adjustment process of the storage layer plate assembly 1, which is conducive to the storage layer plate assembly 1 to smoothly complete the vertical position height adjustment process.At the same time, after the vertical position height of the storage layer board assembly 1 is adjusted and locked, the compression nut 202 of the safety guide assembly 2 is tightened and pressed against the surface of the shelf side panel 3, so that the storage layer board assembly 1 can be locked again when the position height adjustment is completed, which is beneficial to improve the stability of the storage layer board assembly 1 during the use of placing regular cargo packages, and because the guide slot 203 of the safety guide assembly 2 and the top of the adjustment slot 502 of the layer adjustment assembly 5 are both open, the storage layer board assembly 1 can be quickly detached from the top of the shelf side panel 3 by the guide stud 204 and the locking block 501 sliding vertically upward and disengaging from the top of the guide slot 203 and the adjustment slot 502 respectively. The disassembly method of the storage layer board assembly 1 between the two side shelf side panels 3 is simple and easy to operate, which makes it convenient to quickly disassemble the storage layer board assembly 1 for regular maintenance, and at the same time, it is convenient to flexibly combine and set the number of storage layer board assemblies 1, which is beneficial to further improve the storage layer board assembly 1 Flexibility in use. It should be noted that when the storage shelf assembly 1 is removed from the shelf side panels 3 on both sides, the storage shelf assembly 1 should be removed in sequence from top to bottom. Specifically, in the use of the storage shelf assembly 1, since the storage shelf assembly 1 has the function of expanding the storage area, when the placed cargo packages exceed the front and rear edges of the storage board 102, the locking screws 108 are loosened, and then the slide plate 106 is longitudinally slid along the sliding groove 105 and tightened to press the locking screws 108 against the bottom surface of the slide plate 106 at the end of the sliding, so that the distance between the extension plate 101 and the storage board 102 can be expanded and adjusted, and then the storage area on the top of the storage shelf assembly 1 can be expanded. Therefore, when the cargo packages placed on the storage board 102 exceed the front and rear edges of the storage board 102, the storage area can be expanded by the storage shelf assembly 1. The placement stability of the placed cargo packages can be improved, and the risk of cargo packages falling and being damaged can be avoided.
