Detailed Description

The following specific examples are given by way of illustration only and not by way of limitation, and it will be apparent to those skilled in the art from this disclosure that various changes and modifications can be made in the examples without inventive faculty, and yet still be protected by the scope of the claims.

Fig. 1 shows a board placing rack of the present invention, which includes a bottom frame 1 arranged in a flat-laying manner, and a middle partition 2 arranged on the bottom frame 1 in an upright manner and used for a board to lean against, wherein the middle partition 2 extends from left to right and divides the bottom frame 1 into front and rear sides, the front and rear side regions on the bottom frame 1 can be used for placing the board, and the front and rear sides are divided equally to ensure the balance of the front and rear sides of the placing rack, so as to ensure the stability of the placing rack. The rack is mainly used for placing plates, most of which are rectangular, so that the overall shape of the base frame 1 is preferably rectangular to adapt to the placement of the plates, and two parallel edges of the rectangular base frame extend along the left-right direction and the other two parallel edges extend along the front-back direction. During the in-service use, the panel is in the front and back both sides region of standing upright form placing on chassis 1, then inclines towards the centre of rack, and then leans on in the middle on separating fender 2, therefore the middle fender 2 that separates not only plays two even accommodation space's in front and back effect in the rack, still plays the supporting role to the panel. When a sheet material is placed on the base frame 1, although it is supported and restrained by the intermediate barrier 2 in the front-rear direction, it is not restrained in the left-right direction, and it may be left from the rack in the left-right direction, so that the rack further includes a left front bar 41 and a left rear bar 51 at the left end of the intermediate barrier 2, and a right front bar 42 and a right rear bar 52 at the right end of the intermediate barrier 2. The left front baffle rod 41 spans on the left side of the front area of the middle baffle 2, the right front baffle rod 42 spans on the right side of the front area of the middle baffle 2, and the left front baffle rod and the right front baffle rod block the plate in the left-right direction in the area of the placement frame positioned on the front side of the middle baffle 2; the left rear baffle rod 51 spans the left side of the rear area of the middle baffle 2, the right rear baffle rod 52 spans the right side of the rear area of the middle baffle 2, and the left rear baffle rod and the right rear baffle rod block the plate in the left-right direction in the area of the placement frame behind the middle baffle 2; therefore, the plate is fully limited on the placing frame, and the safety of the plate is ensured.

Considering the shape of the sheet material, it can be seen that when the sheet material leans against the intermediate barrier 2, the upper side edge line of the sheet material is in contact with the intermediate barrier 2, and the upper side edge line of the sheet material extends in the left-right direction, so that the sheet material can be maintained in a leaning state only by supporting a plurality of discrete positions on the upper side edge line, and the entire upper side edge line is not required to be supported by the intermediate barrier 2, and correspondingly, the intermediate barrier 2 is not required to be manufactured as a continuous whole, thereby reducing the manufacturing cost. The upper side edge line of the plate is discretely supported, and one condition is that the middle position of the upper side edge line of the plate is supported, so that the plate is supported in a balanced manner, and left and right deflection cannot occur; one is that the upper side line of the plate has at least two positions to be supported, and the plate is stably supported. According to the conclusion obtained by the above analysis, it is preferable that the middle partition 2 includes a plurality of first support columns 3 vertically fixed on the base frame 1, and the first support columns 3 are sequentially arranged from left to right, and according to the characteristic description that the middle partition 2 extends from left to right and equally divides the rectangular base frame 1 into front and rear sides, it can be known that the plurality of first support columns 3 are arranged into a straight line from left to right, and when a plate placed on the rack leans against the middle, the side lines of the upper side of the plate lean against the first support columns 3, and each first support column 3 is in contact with the plate. Therefore, the manufacturing cost of the middle baffle 2 is saved, and the stable support of the middle baffle 2 to the plate is ensured. Further improve, this embodiment prefers first bracing piece interval is evenly arranged, makes panel receive balanced support, further guarantees the stability and the safety of panel.

Due to the fact that the types of the plates are various and the sizes of the plates are different, two situations can occur on the premise that the length of the first supporting column 3 is determined, one situation is that the height of the side edge of the upper portion of the plate is equal to or lower than the height of the highest point of the first supporting column 3 when the plate leans against the first supporting column 3, and the plate leans against the first supporting column 3 through the side edge of the upper portion of the plate; one is that the height of the upper side edge of the sheet material is higher than the height of the highest point of the first support column 3 when the sheet material leans against the first support column 3, and the sheet material leans against the first support column 3 through the side surface of the sheet material. In the two situations, the first situation is an ideal leaning state, and in the second situation, the plate exceeds the height of the highest point of the first support column 3, which may cause the instability of the first support column 3 to support the plate, and meanwhile, the upper end of the first support column 3 abuts against the side surface of the plate, which may cause the side surface to be damaged, thereby causing the damage of the plate, so the second leaning state should be avoided. For the support of guaranteeing panel be above-mentioned first condition all the time, just need the upper end of first support column 3 to be higher than the upper portion side line of panel all the time, for the panel that adapts to multiple size difference, improve the compatibility of this rack, the preferred first support column 3 of this embodiment comprises vertical branch 31 and the location installation pole 32 that is located vertical branch 31 below and fixes on chassis 1 to vertical branch 31 is dismantled and assembled to be fixed on location installation pole 32, is pegging graft between preferred vertical branch 31 and the location installation pole 32. During actual installation, the vertical supporting rods 31 fixed on the positioning installation rod 32 are of the same specification, and the placement of plates within a certain specification range is met; when the plate to be placed exceeds the range, all the vertical supporting rods 31 are replaced by a batch with larger length, and all the vertical supporting rods 31 of a new batch are consistent in specification. Above-mentioned scheme has improved the compatibility of this rack through the change of the vertical branch 31 of different specifications, nevertheless because vertical branch 31 is discrete, needs to change one by one, has increased workman's work load, has reduced efficiency. To above-mentioned problem, this embodiment is preferred middle baffle 2 still includes crossbeam 6, and all vertical branch 31 all is fixed through the upper end on crossbeam 6, and all vertical branch 31 of here are same specification, just so make vertical branch 31 and crossbeam 6 constitute a whole to realize that all vertical branch 31 once only install on location installation pole 32, accelerated the installation effectiveness greatly, also effectively improved all vertical branch 31's support intensity simultaneously, thereby make panel receive more stable support. In addition, when a whole body formed by the plurality of vertical supporting rods 31 and the cross beam 6 is manufactured in a factory machining process, the specification of each vertical supporting rod 31 in each whole body is consistent, and the specification of each vertical supporting rod 31 in different whole bodies is different, so that the whole body formed by one proper vertical supporting rod 31 and the cross beam 6 can be selected according to the size of a plate on a project site and is installed on the positioning installation rod 32, and the replacement efficiency of the vertical supporting rods 31 is accelerated.

Since the aforementioned left front bar 41, left rear bar 51, right front bar 42 and right rear bar 52 are all provided on the intermediate barrier 2, and the intermediate barrier 2 is composed of the discrete first support bars 3 and cross members 6, the left front bar 41, left rear bar 51, right front bar 42 and right rear bar 52 are provided on the vertical struts 31 or on the cross members 6. However, the vertical struts 31 are all used for leaning of the sheet, and the left front bar 41, the left rear bar 51, the right front bar 42 and the right rear bar 52 are located at the left and right ends to limit the sheet, so it is preferable that the left front bar 41 and the left rear bar 51 are fixed on the cross beam 6 through the upper ends, the right front bar 42 and the right rear bar 52 are fixed on the cross beam 6 through the upper ends, and the left front bar 41, the left rear bar 51, the right front bar 42 and the right rear bar 52 all extend outwards back to the cross beam 6, so as to block the sheet. Since the whole body formed by the cross beam 6 and the vertical strut 31 is detachable from the underframe 1, the left front stop lever 41, the left rear stop lever 51, the right front stop lever 42 and the right rear stop lever 52 fixed on the cross beam 6 can also be detached from the underframe 1 along with the whole body, but if the left front stop lever 41, the left rear stop lever 51, the right front stop lever 42 and the right rear stop lever 52 are fixed on the cross beam 6 only through the upper ends, the strength is obviously lower, and the structure is unstable. To the above problem, so the preferred left front pin 41 and right front pin 42 of this embodiment are the slope form and extend to chassis 1 from the upper end to the front below, and left back pin 51 and right back pin 52 are the slope form and extend to chassis 1 from the upper end to the back below, make after the installation left front pin 41, left back pin 51, right front pin 42 and right back pin 52 all support and lean on chassis 1, guarantee the stability of structure, improve the intensity of four pins simultaneously, guarantee its full restriction to panel along left and right direction. Further improve, the shape profile of chassis 1 has been preferred in the foregoing for the rectangle, and have two edges that are parallel to each other to extend along left right direction and two other edges that are parallel to each other to extend along the fore-and-aft direction in the rectangle chassis, the lower extreme of the above-mentioned four pin poles of this embodiment preferred supports respectively and leans on the juncture at two edges that the rectangle chassis is mutually perpendicular, just so make as long as panel is located the space region of rack front and back both sides, panel moves left or right and just can certainly receive arbitrary one in the above-mentioned four pin poles and block, guarantee the safety of panel, in addition, four pin poles slope form sets up and also make partly of panel expose, thereby be convenient for workman's the seek and take.
