Connector 117Can on outer vertical plate 111, arrange multiple, in the time that connector 117 is two, outside being just separately positioned onThe two ends of riser 111, when the quantity of connector 117 is during more than two, these connectors 117 canAlong longitudinally evenly arranging of outer vertical plate 111. For example be provided with three connectors 117, by wherein twoThe individual two ends that are arranged on outer vertical plate 111, another one is arranged on the connector 117 at outer vertical plate 111 two endsMidpoint. And be provided with at the top of inner vertical plate 113 to the clinch 119 of slot 115 interior extensions,As shown in Figure 5, this clinch 119, for being connected with the chassis cladding plate 40 on chassis 10, spreads in realityIf when the cladding plate 40 of chassis, chassis cladding plate 40 is overlapped on the upper surface of clinch 119.
As shown in Figure 7, after end wall 30 is connected with chassis 10, this is outer for the lateral surface structure of end wall 30Side is towards the outside of pallet box. By the I in Fig. 7 is in Fig. 8 and amplifies and can find out,Be provided with the connecting hole 50 for being connected with connector 117 in the bottom of end wall 30, end wall 30 withChassis 10 is exactly the connection that completes the two by connector 117 is inserted to this connecting hole 50 while connection.Connecting hole 50 shown in Fig. 8 is circular, is used for coordinating with the pin shown in Fig. 5. Fig. 9 shows and connectsThe another kind of embodiment that connects hole 50, connecting hole 50 is rectangle, and is used for protruding with shown in Fig. 6Hook coordinates.
The medial surface structure of end wall 30 as shown in figure 10, after end wall 30 is connected with chassis 10, is somebody's turn to doMedial surface is towards the inside of pallet box. By the II in Figure 10 is in Figure 11, amplify passableFind out, be provided with the first otch 70 in the bottom of end wall 30, the effect of this first otch 70 is,In the time that inserting slot 115, end wall 30 can dodge out above-mentioned clinch 119. In addition, according toDifferent situations can also arrange in the bottom of end wall 30 other otch except the first otch 70 withReach the object of dodging clinch 119.
Below in conjunction with accompanying drawing, end wall and end wall were further detailed with being connected of chassis.
Get back to Fig. 7, can find out, end wall 30 comprises the end wall column 31 that is arranged on end wall 30 both sides,End wall cladding plate 33 between the end wall column 31 of both sides and being positioned under the end wall of end wall 30 bottomsBeam 35.
With reference to Figure 10, end wall column 31 comprises orthogonal the first riser 311 and the second riser 313,The first riser 311 is parallel with outer vertical plate 111 in the time that end wall 30 connects with chassis 10 (also with inner vertical plate113 is parallel), the second riser 313 in the time that end wall 30 is connected with chassis 10 vertical with outer vertical plate 111 (alsoVertical with inner vertical plate 113), above-mentioned the first otch 70 is just arranged on the first riser 311 of both sidesRelative base angle place (referring to Figure 11, the dotted line shown in Figure 11 is the edge of the first riser 311).On the first riser 311, be provided with after the first otch 70, also will guarantee on the first riser 311 with firstThe width of otch 70 adjacent parts is less than the side girders slot 23 of the chassis side girders 20 shown in Fig. 5Width. Like this, the first riser 311 in the time end wall 30 being inserted to the slot 115 of chassis end side bar 11Can not interfere with clinch 119.
From Figure 10, it can also be seen that, end wall underbeam 35 be connected to both sides the first riser 311The bottom on one surface, this first surface refers to after end wall 30 is connected with chassis 10 outside pallet boxThe surface of portion. Above-mentionedly be arranged under end wall for 50 of connecting holes that are connected with connector 117On the surface of beam 35 away from first surface.
Or in Figure 10, end wall cladding plate 33 is connected to the second surface of the first riser 311 of both sidesUpper, this second surface is positioned at a side relative with first surface on the first riser 311, i.e. this second tableFace refers to after end wall 30 is connected with chassis 10 surface towards pallet box inside. At assembling end wall 30During with chassis 10, for end wall cladding plate 33 is not interfered with clinch 119, end wall cladding plate 33Lower limb must not be lower than the top edge of the first otch 70.
About being connected of end wall cladding plate 33 and the first riser 311, can adopt the mode of welding, andBecause end wall cladding plate 33 is very thin, thickness is in 0.3 ~ 0.4mm left and right conventionally. Therefore can in the time of weldingEnd wall cladding plate 33 is welded on the first riser 311 and end wall underbeam 35 simultaneously, and at the first riser311 with the intersection of end wall underbeam 35, end wall cladding plate 33 is the natural transition state shown in Figure 12.
In addition, preferably, end wall column 31 can directly use angle bar, orthogonal by angle barOne in two flat boards uses as the first riser 311, and another makes as the second riser 313With.
And, in order to strengthen and improve the structure of end wall 30, equally preferably, also can as shown in Figure 7,Top with the first surface of the first riser 311 in both sides arranges end wall upper beam 37.
Connection procedure below in conjunction with brief description of the drawings end wall 30 with chassis 10.
First with reference to Figure 13, the structure of clinch 119 is described first. As can be seen from Figure 13,Clinch 119 comprises that top from inner vertical plate 113 is to the horizontally extending level board 1191 of slot 115,And the hang plate 1193 being obliquely installed to inner vertical plate 113 from the end of level board 1191, and waterBetween flat board 1191 and hang plate 1193, it is arc transition.
Continue with reference to Figure 13, end wall 30 inserts in slot 115 obliquely, now due to the first otch70(is referring to Figure 11) existence, hang plate 1193 can not touch on end wall cladding plate 33 with end wall verticalThe part that post 31 connects, but contact with end wall underbeam 35 through the first otch 70. Subsequently by end wall30 rightings (referring to Figure 14), make connector 117 insert end wall underbeam 35, can complete end wall 30Assembling with chassis 10.
As shown in figure 15, pallet box in use end wall 30 can be subjected to displacement and to hang plate 1193Mobile, still, due to the existence of the first otch 70, when end wall 30 inserts, hang plate 1193 is and endWall underbeam 35 contacts, and therefore the width of slot 115 can suitably reduce, even end wall 30 like thisTouch as shown in figure 15 arc transition place between level board 1191 and hang plate 1193 also all rightEnsure that connector 117 and end wall underbeam 35 have enough amounts of articulating, ensure that end wall 30 can be from not insertingIn groove 115, depart from, thereby guaranteed that end wall 30 is connected with the reliable of chassis 10.
Mentioning above between the level board 1191 of clinch 119 and hang plate 1193 is arc transition,The advantage arranging is like this, the process of carrying out righting after end wall 30 is inserted to slot 115 obliquelyIn, the top edge of the first otch 70 can be by the round and smooth mistake between level board 1191 and hang plate 1193The place of crossing is blocked, thereby can be successfully by end wall 30 rightings, for end wall 30 and the assembling on chassis 10 are carriedSupply facility. The existence of level board 1191 can facilitate chassis cladding plate 40(referring to Fig. 5) installation.And hang plate 1193 both can play end wall 30 to enter in the time that end wall 30 is inserted to slot 115 obliquelyThe effect of row guiding, also contributes to strengthen the intensity of clinch 119, and clinch 119 is being heldWhen the shock of wall 30, can not be out of shape easily.
In addition, as shown in figure 13, for end wall 30 can be inserted in slot 115 obliquely, withTime also in order to facilitate connector 117 to insert in end wall underbeam 35 when the righting end wall 30, can connectThe end that fitting 117 is positioned at slot 115 is set to have inclined plane, and this place, inclined planePlane is crossing with the bottom surface of outer vertical plate 111 and slot 115, i.e. the setting on this inclined plane makes connector 117Top edge be less than lower limb, be so just conducive to end wall 30 and insert obliquely slot 115, simultaneously alsoBe convenient to connector 117 in the process of righting end wall 30 and insert end wall underbeam 35 through connecting hole 50In. Protruding hook shown in pin as shown in Figure 5 and Fig. 6, all adds in the end that is positioned at slot 115Work has gone out inclined plane.
Mention above, in some cases, except the first otch 70 is set also in the bottom of end wall 30Other otch can be set, below the another kind of embodiment about otch with regard to accompanying drawings.
Identical with front a kind of embodiment, still can be with reference to accompanying drawing above, end wall cladding plate 33 weldsOn the second surface of the first riser 311 of both sides, the first otch 70 is arranged on the first riser of both sides311 relative base angle places, the setting of connecting hole 50 does not also change. Difference is, in this realityExecute in mode, the height of end wall underbeam 35 decreases, simultaneously in order to ensure end wall underbeam 35 and endThe abundant contact of wall cladding plate 33, as shown in figure 16, need to move down the lower limb of end wall cladding plate 33,Will cause like this lower limb of end wall cladding plate 33 lower than the top edge of the first otch 70, to such an extent as to subtractThe little height of the first otch 70. In order not make the first otch 70 lose efficacy, also need end wall cladding plate33 parts that overlap with the first otch 70, and the portion that is connected with end wall underbeam 35 of end wall cladding plate 33At least a portion of dividing is set to the second otch 90, to ensure that cut out portion has enough height and wideDegree. In Figure 16, dotted line represents the edge of the first riser 311, end wall cladding plate 33 and the first otch70 parts that overlap are positioned at the right side of this dotted line, the part that end wall cladding plate 33 is connected with end wall underbeam 35Be positioned at the left side of this dotted line. Mention above, as shown in figure 12, end wall cladding plate 33 is positioned at the first riser311 and the part of end wall underbeam 35 intersections be nature transition state, because this nature transition portion inclinesTiltedly be arranged between the first riser 311 and end wall underbeam 35, will protrude from end wall underbeam 35. ForAvoid hang plate 1193 to contact with this nature transition portion inserting when end wall 30, end wall is being coveredWhen being set to the second otch 90, at least a portion of the part that plate 33 is connected with end wall underbeam 35 should will be somebody's turn to doNature transition portion is removed.
Preferably, the top edge of the second otch 90 is not less than the top edge of the first otch 70, so justCan in the case of the size of the first otch 70 is definite, ensure that cut out portion has maximum height. WithTime, under the end wall using due to pallet box, depth of beam is conventionally all smaller, so adopt this enforcementMode just can be used the end wall underbeam of common-use size, does not need to make separately end wall underbeam.
The process that the end wall of present embodiment 30 is connected with chassis 10 can be with reference to Figure 17 to Figure 19,Now two of hang plate 1193 ends still can be through the first otch 70 of both sides not with end wallThe part contact being connected with the first riser 311 on cladding plate 33. And the longitudinal pars intermedia of hang plate 1193Branch and the part contact (referring to Figure 18) being connected with end wall underbeam 35 on end wall cladding plate 33. But asAbove-mentioned, the thickness of end wall cladding plate 33 is very little, only has 0.3 ~ 0.4mm left and right, so wholeBetween hang plate 1193 and end wall underbeam 35, also only there is the interval of 0.3 ~ 0.4mm, can look approxFor hang plate 1193 contacts with end wall underbeam 35, like this, also just can suitably reduce equally slot115 width.
As shown in figure 19, even if end wall 30 touches between level board 1191 and hang plate 1193Arc transition place, also can also ensure that connector 117 and end wall underbeam 35 have enough amounts of articulating,Ensure that end wall 30 can not depart from from slot 115, thereby guaranteed the reliable of end wall 30 and chassis 10Connect.
The present invention is illustrated by above-described embodiment, but should be understood that, above-mentioned enforcementExample is the object for giving an example and illustrating just, but not is intended to the present invention to be limited to described embodimentIn scope. In addition it will be appreciated by persons skilled in the art that the present invention is not limited to above-mentioned enforcementExample, can also make more kinds of variants and modifications according to instruction of the present invention, these variants and modificationsAll drop in the present invention's scope required for protection. Protection scope of the present invention is wanted by attached rightAsk book and equivalent scope thereof to define.
