Elastic component preferentially from cylindroid helical-coil compression spring, can also be other elastic components such as rubber, spring leaf.According to bullet The difference of property part planform, alignment pin can also be cancelled.Rotating shaft 414 is preferably vertical with end wall body 110 so that jam plate Plane where 430 rotating path is parallel with the place plane of end wall body 110, in this way, no matter under opening or locked state, lock The outermost surfaces of plate 430 do not protrude from the outer surface of end wall back timber 120, and end wall back timber 120 plays protection to lockset 400 Effect, after end wall 100 can be avoided to fold, the damage such as the extruding of side wall 200 to lockset 400.Being designed and sized to of rotating shaft 414 makes lock Plate 430 can be rotated freely.

From Fig. 5 and 6, stopper 440 is connected on side wall column 220, and including fixed part 441 and stopper section 442. Fixed part 441 is fixedly connected with side wall column 220.Stopper section 442 is tabular, parallel to side wall body 210 to pallet box end wall 100 inner sides extend.Fixed part 441 and stopper section 442 are integrally formed, and plane where the two is mutually perpendicular to.

As Fig. 6 is shown specifically, stopper section 442 includes stopper section body 442a, the first limiting section 442b, guiding surface 442c and the second limiting section 442d.First limiting section 442b is close to the side of fixed part 441 and from the fixed part of fixed part 441 The vertical surface that top surface 441a is extended vertically upwards.Guiding surface 442c is from the first limiting section 442b highest position, Xiang Yuan It is sloped downwardly from fixed part 441 1.Second limiting section 442d is laterally away from the direction of fixed part 441 from stopper section body 442a mono- Protrude and form hook-type projection, and its upper surface smoothly connects with guiding surface 442c, and at grade.Second is spacing Portion 442d size just can insertion end stand like a wall post 130 U-shaped portion 132 end wall sticking part 132b spacing hole 134 in, such as scheme 13rd, 15 and 16 optimally show.

The sealed and releasing process of pallet box 1 is illustrated below.

The sealed process of pallet box 1：

From Fig. 7-Fig. 9, operator lifts side wall 200 first, and when side wall 200 arrives erectility, side wall 200 is fixed On chassis.Next lifts end wall 100, as case inner face of the end face of end wall 100 along side wall lifts, is arranged on end wall 100 Jam plate 430 locking part 432 touch first the stopper 440 being arranged in side wall stopper section 442 guiding surface 442c (Fig. 8).If now continuing to pull at end wall 100, locking part 432 is against guiding surface 442c and moves up, guiding surface 442c provides upward support force, and the support force is downward more than what the spring being arranged between end wall 100 and locking part 432 provided Elastic force so that locking part 432 continues along guiding surface 442c upward slidings.Herein, in order that locking part 432 can smoothly edge Guiding surface 442c upward slidings, inclined-plane that the bottom of locking part 432 is arranged to match with guiding surface 442c (such as Fig. 7 and Shown in Fig. 8), this inclined-plane coordinates with guiding surface 442c so that lockset can smoothly complete automatic locking process.Work as locking part 432 when crossing guiding surface 442c top, and locking part 432 falls along the first limiting section 442b, the close end of locking part 432 The inner surface of wall side is close to the first limiting section 442b surface, and in the presence of elastic component 420, under locking part 432 End is leaned against on the fixed part top surface 441a of fixed part 441 (Fig. 9).Meanwhile as shown in figure 13, the second limiting section 442d insertions are set In spacing hole 134 on end wall column 130.As shown in figure 15, the side elevation of stopper section body 442a close side wall 200 is tight Paste in the side wall column sticking part 132c of the U-shaped portion 132 of the end wall column 130 U-shaped portion on facade, in this way, passing through lock 410th, jam plate 430 and stopper 440 and the mutual cooperation of end wall column 130 act on, the opposing sidewalls 200 of end wall 100 it is forward and backward, left, Right, upper and lower is fixed upwards.Because side wall 200 has been relatively fixed with chassis, end wall 100 by side wall 200 with Chassis is also relatively fixed.The sealed process of whole lockset operates lockset without operator, it is only necessary to which operator is simultaneously to case foreign side Make lockset sealed to pull end wall.Also, after lockset is sealed, the pressure of elastic component 420 makes jam plate remain at latched position, Lockset is set to remain locked state.Further, since the first limiting section 442b is located at the inner side of jam plate, therefore, first can be passed through Limiting section 442b prevents end wall 100 from toppling over into case, locked state lower end wall 100 is kept stable.

Figure 10 and Figure 11 shows the unlocking manner of lockset 400.In releasing process, operator is with hand lifting or mediates jam plate 430 make it be rotated up to around rotating shaft 414 or close to highest position H, and highest position H is the top of fixed hole 133, And the direction into case pushes away end wall 100 simultaneously for holding.Now, the locking part 432 of jam plate 430 crosses the stopper section 442 of stopper 440 First limiting section 442b so that jam plate 430 separates with stopper 440.Thus, the second limiting section 442d of stopper also from be arranged on end Depart from the spacing hole 134 to stand like a wall on post 130, lockset 400 is in released state.The unlocking motion can be with one-handed performance, so Operator can two hands operate two locksets simultaneously, two locksets unlock simultaneously, and operating efficiency is greatly improved.

The matching relationship and size design of each part related to lockset 400 is described more particularly below.

Figure 12 is the front view in Fig. 1 A portions.Figure 13 and Figure 14 is the sectional view that is cut along the I-I lines in Figure 12, and Figure 13 shows What is gone out is that lockset 400 is in locked state, and Figure 14 is illustrated that the released state of lockset 400.Figure 15 is along the H-H lines in Figure 12 The sectional view cut, Figure 16 is checks the sectional perspective schematic diagram in A portions from box house, and now, lockset 400 is in sealed shape State.

In the unlocked state, as shown in figure 14, the second limiting section 442d is not placed in spacing hole 134.In locked state Under, as shown in Figure 13,15 and 16, the second limiting section 442d and spacing hole 134 size match, and the second limiting section 442d is housed In spacing hole 134, the locking part 432 of jam plate 430 is placed on the fixed part 441 of stopper 440.As an example, specific size is set Meter is as follows：

Elastic force is downwardly applied in elastic component 420 and makes the lower edge of the retainer 433 of jam plate 430 in extreme lower position During point L (Figure 17), the vertical range A (Figure 17) of the upper open end of the upper surface of retainer 433 to fixed hole 133 is more than or equal to First limiting section 442b of stopper section 442 highest position to the fixed part top surface 441a of fixed part 441 vertical range A1 (Figure 20), with allow the locking part 432 of jam plate 430 smoothly cross stopper section 442 the first limiting section 442b highest order Put and be resisted against on the fixed part top surface 441a of fixed part 441, locking part 432 can also be resisted against the first limiting section simultaneously On 442b.

The lower open end of fixed hole 133 is to the distance B (Figure 17) of the lower surface of spacing hole 134 and the fixation of fixed part 441 Portion top surface 441a to the distance B1 (Figure 20) of the second limiting section 442d bottom matches, to be in sealed in lockset 400 During state, the second limiting section 442d is just inserted in spacing hole 134, also ensures that the locking part 432 of jam plate 430 can be supported stably Lean against on the fixed part top surface 441a of fixed part 441.

The height C (Figure 17) and the second limiting section 442d of spacing hole 134 height C1 (Figure 20) match, to cause pallet In the vertical state of group, end wall 100 is fixedly connected case with chassis 300.

The U-shaped portion 132 of end wall column 130 is less than in the thickness D (Figure 17 and 18) of the wall portion close to the side of side wall column 220 The width D 1 (Figure 21) in the space formed between stopper section 442 and side wall column 220.So, when lockset 400 is sealed, backstop Portion 442 and side wall column 220 just bare terminal end stand like a wall post 130 U-shaped portion 132 the close side of side wall column 220 wall portion.

The size E (Figure 17 and 18) of the width of spacing hole 134 and the second limiting section 442d of stopper 440 length E1 (figures 21) match, to enable the second limiting section 442d to be smoothly placed in spacing hole 134.

The distance F of the end wall sticking part 132b of the U-shaped portion 132 of end wall column 130 lateral surface to the interior plate of casing (schemes 18) the length F1 (Figure 20) that stopper section body 442a is protruded from the second limiting section 442d is of substantially equal.If F1 is significantly greater than F, then cause the second limiting section 442d to advance by leaps and bounds in case and projection is formed in case, this projection can influence end wall and be stacked to the extreme end of chassis Height after the stationarity of wall, and pallet box folding, can also cause damage to the bottom plate on chassis 300, can after pallet box group is vertical Built-in goods can be damage.If F1 is significantly less than F, then the second limiting section 442d can not provide reliable position-limiting action.

The inner surface of the locking part 432 of jam plate 430 to the end wall sticking part 132b of U-shaped portion 132 outer surface away from Insertion depth G1 (Figure 20) from G (Figure 18) and stopper section body 442a matches, to enable the locking part 432 of lockset 400 Enough the first limiting section 442b against stopper section 442, locking part 432 can make against the first limiting section 442b of stopper section 442 The locked state of lockset 400 is more stable.

The minimum point of second limiting section 442d upper surface to the fixed part top surface 441a of fixed part 441 vertical range m The minimum point that (Figure 20) is greater than the 0, and second limiting section 442d upper surface will be less than the fixed part top surface of fixed part 441 441a, with ensure it is sealed during, the base of the locking part 432 of jam plate 430 can touch leading for the stopper section 442 of stopper 440 To inclined-plane 442c, the automatic locking of lockset is realized.

Based on above technical scheme, there is following beneficial effect relative to prior art for the utility model：
