Description

Technical Field

[0001] The utility model belongs to the technical field of container equipment, and particularly relates to a lightweight folding and sealed container. Background Art

[0002] A container is an important integrated transportation equipment in the logistics industry. Whether it is land transportation or sea transportation, it is inseparable from using containers to transport materials. At present, most of the containers used in the industry are containers with fixed shapes and volumes, and some are containers with expandable volumes. However, the existing containers at present are relatively large in volume during empty transportation and occupy a lot of space. Moreover, in order to ensure their own structural strength, the self-weights of containers are relatively heavy (the self-weight of a 1C type dry cargo container is generally about 2 tons, and the self-weight of an insulated container is 3 - 4 tons). All these undoubtedly cause waste of transportation resources. In addition, in the high-humidity, high-temperature and high-salt mist environment in coastal areas, the sealing conditions of containers are not ideal, resulting in goods being eroded by rainwater, salt mist, etc.

[0003] Based on the above problems, there is an urgent need for a container with a lightweight structure that can be folded during empty transportation to avoid occupying more transportation resources. At the same time, since the foldable container faces changes in the positions of structural members during the folding and unfolding processes, it is also necessary to design a sealing structure for the container to ensure that the unfolded container has good sealing performance. This type of container can solve the problems of the relatively large self-weight of the container, the relatively large volume during empty transportation, resulting in waste of transportation resources, and the relatively poor sealing performance after unfolding.

[0057] Sealing structures 10 are provided at the connecting edges between the end plate 3 and the adjacent side plate 4, the connecting edges between the bottom plate 1 and the four walls, and the connecting edges between the top plate 2 and the four walls.

[0058] It should be noted that the frame structure preferably adopts steel profiles. Steel profiles have the advantages of light weight, high strength, strong plasticity, long service life, good weather resistance, etc., which can meet the structural requirements; the vertical columns on both sides of the frame preferably adopt double C-shaped steel, and the cross beams at the upper and lower ends of the frame adopt rectangular steel pipes; the panel is preferably made of aluminum alloy corrugated board with a thickness of 2 mm, and the density of aluminum alloy is generally about 2.5-2.88 g / cm; compared with alloy steel, aluminum alloy has good corrosion resistance and plasticity, is suitable for various pressure processing, and is widely used in mechanical manufacturing; in addition, aluminum alloy also has good corrosion resistance, high reflectivity to light, heat and radio waves, good surface performance, basically non-toxic, sound absorption, good acid resistance; good anti-nuclear radiation performance, small elastic modulus, excellent casting and welding performance, good impact resistance, gluing performance and surface treatment performance, etc.; the aluminum alloy plate used in the present invention can meet the structural requirements of all aspects of the container.

[0059] In specific implementation, by setting the side plate 4 and the bottom plate 1 to be connected by a rotatable hinge mechanism 5, the side plate 4 can be rotated and folded inward relative to the bottom plate 1, constituting a link in the overall unfolding and folding process of the container;

[0060] By setting the side plate 4 and the top plate 2 to be movably connected by a buckle locking mechanism 6, the fixation and separation of the side plate 4 and the top plate 2 can be realized, constituting a link in the overall unfolding and folding process of the container;

[0061] By setting the connection between the side plate 4 and the adjacent end plate 3 to be movably connected by a pressing plate locking mechanism 7, the fixation and separation of the side plate 4 and the end plate 3 can be realized, constituting a link in the overall unfolding and folding process of the container;

[0062] By setting the lower end and the upper end of the end plate 3 to be movably connected to the bottom plate 1 and the top plate 2 by a pin locking mechanism 8, the fixation and separation of the end plate 3 from the bottom plate 1 and the top plate 2 can be realized, so that the end plate 3 can be rotated and folded inward, and the top plate 2 can be stacked on the upper end of the bottom plate 1, constituting a link in the overall unfolding and folding process of the container;

[0063] The frame adopts steel materials and the panel adopts corrugated aluminum alloy materials, which can effectively reduce the weight of the container on the premise of ensuring the overall strength and achieve lightweight;

[0064] By setting a sealing structure at the connection edges between the end plate 3 and the adjacent side plate 4, between the bottom plate 1 and the four walls, and between the top plate 2 and the four walls, the sealing function of the container after unfolding can be realized without affecting the folding function of the container.

[0065] In the implementation provided by the present invention, such as Figure 2 , Figure 3 andFigure 8 As shown, a folding linkage mechanism 9 is installed between the four corners of the end plate 3 and the top plate 2; the folding linkage mechanism 9 includes a guide rail 901, a long connecting rod 902, and a short connecting rod 903;

[0066] The guide rail 901 is fixedly installed on the top plate 2; one end of the long connecting rod 902 is slidably connected to the guide rail 901, and the other end is hingedly connected to the short connecting rod 903; one end of the short connecting rod 903 away from the long connecting rod 902 is hingedly connected to the end plate 3.

[0067] It should be noted that a ball head 904 is provided at one end of the long connecting rod 902, and preferably an axle pin structure is used for the movable connection with the long connecting rod 902; the guide rail 901 is preferably fixed to the top plate 2 by screws; a chute is provided inside the guide rail 901, and the ball head 904 is clamped in the chute and can move along the chute; the opposite folding linkage mechanisms 9 are connected by a cross bar 906 fixed to the upper end of the end plate 3, and the cross bar 906 is preferably fixed to the end plate 3 by screws; a through hole perpendicular to and intersecting with the chute is also provided in the middle of the guide rail 901, and a through hole is also opened at the corresponding position of the top plate 2 and the through hole, and a positioning pin 905 is inserted between the two through holes; the positioning pin 905 is inserted from the outside of the top plate 2 and passes through the guide rail 901, and the ball head 904 of the long connecting rod 902 can be limited at both ends of the chute.

[0068] It should be noted that when the container is in the unfolded state, one end of the long connecting rod 902 with the ball head 904 is located at the end of the guide rail 901 away from the end plate 3, and the positioning pin 905 passes through the through hole on the top plate 2 from the outside of the side of the top plate 2, and then passes through the through hole of the guide rail 901, so as to limit the ball head 904 to one end of the guide rail 901; in the process of the container changing from the unfolded state to the folded state, the top plate 2 is lifted a certain distance by a forklift or other lifting equipment; the guide rail 901 rises with the top plate 2, driving the ball head 904 in the slide groove and the long connecting rod 902 and the short connecting rod 903 to swing upward together; due to the presence of the positioning pin 905, the ball head 904 cannot move to the other end of the guide rail 901, and therefore the upper end of the end plate 3 will be driven to tilt toward the inside of the container through the long connecting rod 902 and the short connecting rod 903; at this time, the positioning pin 905 is removed, and the top plate 2 is lowered; the end plate 3 will continue to move inward under the action of its own gravity 905 is installed.

[0069] In the specific implementation, the folding linkage mechanism 9 can realize the linkage function of the unfolding and folding process of the top plate 2 and the end plates 3 on both sides, and drive the end plates 3 to fold and unfold by lifting and lowering the top plate 2, which is convenient and safe to operate; the positioning pin 905 can effectively position the ball head 904 within a certain range, thereby realizing the linkage effect; the setting of the short connecting rod 903 increases the movement freedom of the mechanism, which can effectively prevent jamming during the linkage process.

[0070] In one embodiment, if Figure 4 As shown, the hinge mechanism 5 includes an upper hinge 501, a lower hinge 502 and a damper 503; the upper hinge 501 is installed at the upper end of the damper 503 and hinges the damper 503 to the side panel 4; the lower hinge 502 is installed at the lower end of the damper 503 and hinges the damper 503 to the bottom panel 1; a plurality of hinge mechanisms 5 are arranged between the two side panels 4 and the bottom panel 1.

[0071] It should be noted that the damper 503 is preferably a hydraulic damper 503, which includes a hydraulic cylinder and a hydraulic rod installed in the hydraulic cylinder. The resistance of the hydraulic rod movement is generated by the flow of hydraulic oil in the hydraulic cylinder. The upper end of the hydraulic rod is hinged to the side plate 4 through the upper hinge 501, and the lower end of the hydraulic cylinder is hinged to the bottom plate 1 through the lower hinge 502. During the process of the container changing from the unfolded state to the folded state, the side plate 4 will rotate inwards with the connection between the two as the center relative to the bottom plate 1 and fold to a state parallel to the bottom plate 1. During the rotation of the side plate 4, the hydraulic rod will be driven to move outside the hydraulic cylinder. When the hydraulic rod moves, the hydraulic oil will flow in the two chambers of the hydraulic cylinder and generate a certain resistance to prevent the hydraulic rod from moving outwards. This process can effectively generate resistance to the folding rotation of the side plate 4, so as to prevent the side plate 4 from quickly falling onto the bottom plate 1 due to the action of gravity. The connection edge between each side plate 4 and the bottom plate 1 is preferably connected by 4 hinge mechanisms 5.

[0072] It should be noted that the upper hinge 501 and the lower hinge 502 are preferably fixed to the side plate 4 and the bottom plate 1 by welding or screws respectively. The upper hinge 501 and the lower hinge 502 are rotatably connected to the hydraulic rod and the hydraulic cylinder through shaft pins respectively.

[0073] In specific implementation, by arranging the hinge mechanism 5 with the damper 503 between the side plate 4 and the bottom plate 1, it can effectively prevent the side plate 4 from quickly falling onto the bottom plate 1 due to the action of gravity, thus avoiding potential safety hazards to components and personnel.

[0077] It should be noted that when the container is in the unfolded state, the locking pin 603 extends into the locking pin hole 606 to lock the side plate 4 and the top plate 2; the buckle 601 cooperates with the buckle seat 602 to fasten, fixing the locking pin 603 and the manual operating rod 604 in the above locking position to prevent loosening; the lower end of the manual operating rod 604 is locked by the lock piece 608 to prevent it from tilting and swinging; when the container needs to be folded, manually rotate the lock piece 608 to unlock the lower end of the manual operating rod 604; move the manual operating rod 604 outward, and the manual operating rod 604 swings with the hinge point between its upper end and the locking pin 603 as the center, and at the same time drives the buckle link 607 and the buckle 601 hinged to the upper part of the manual operating rod 604 to move upward together, so that the buckle 601 is disengaged from the cooperation with the buckle seat 602, and then put down the manual operating rod 604; at this time, the buckle locking mechanism 6 is in the unlocked state; preferably, 4 sets of buckle locking mechanisms 6 are adopted between each side plate 4 and the top plate 2.

[0078] In specific implementation, the buckle locking mechanism 6 can conveniently lock and unlock the side plate 4 and the top plate 2 by manual operation, which is time-saving, labor-saving, safe and reliable; the lock piece 608 at the lower end of the manual operating rod 604 can prevent the accidental loosening of the buckle locking mechanism 6 caused by the swinging of the manual operating rod 604 in the locked state.

[0081] It should be noted that in the unfolded state of the container, the end plate 3 and the side plate 4 are locked and fixed to each other through the pressing plate locking mechanism 7; the locking tongue 702 protrudes outside the end plate 3 and can extend under the pressing plate 701; when it is necessary to lock the pressing plate locking mechanism 7, manually lift the pressing plate 701 upward, and the lower part of the middle protruding portion 703 of the pressing plate 701 presses on the locking tongue 702; continue to lift the pressing plate 701 so that the hook-shaped portion at its upper end cooperates with the locking ring 704 for locking. At this time, the pressing plate 701 undergoes a certain elastic deformation, and the locking tongue 702 can be tightly pressed under the pressing plate 701; when unlocking is required, disconnect the locking ring 704 from the pressing plate 701 and lower the pressing plate 701, then the suppression of the locking tongue 702 can be released, and the side plate 4 and the end plate 3 can be separated.

[0082] In specific implementation, through the pressing plate locking mechanism 7, the side plate 4 and the end plate 3 can be effectively and firmly locked and fixed, which is time-saving, labor-saving, convenient and safe.

[0083] In the embodiment provided by the present utility model, as Figure 3 shown, upper mounting seats 201 are provided at the four corners of the top plate 2; lower mounting seats 102 are provided at the four corners of the bottom plate 1; inserting plates 302 are provided at the four corners of the end plate 3; the upper mounting seats 201 and the lower mounting seats 102 are both provided with inserting plate 302 grooves with openings facing the end plate 3; in the unfolded state, the corresponding inserting plates 302 are inserted into the inserting plate 302 grooves of the upper mounting seats 201 and the lower mounting seats 102.

[0084] It should be noted that both the upper mounting seats 201 and the lower mounting seats 102 are fixed at the four corners of the top plate 2 and the bottom plate 1 by an interference fit manner; the inserting plates 302 are preferably fixed at the four corners of the end plate 3 by welding or being made integrally.

[0085] In specific implementation, when the container is in the unfolded state, inserting the insertion plate 302 into the insertion plate 302 grooves of the upper mounting seat 201 and the lower mounting seat 102 can effectively increase the structural strength of the container and prevent it from falling off easily; adopting the above-mentioned plug-in type assembly structure can ensure the smooth disassembly and assembly between the end plate 3 and the top plate 2 and the bottom plate 1 during the conversion process between the unfolded state and the folded state.

[0086] In one embodiment, as Figure 7 shown, the pin locking mechanism 8 is installed at the four corner positions of the bottom plate 1 and the top plate 2, and includes a pin 801 and a baffle 802; the pin 801 includes a pin shaft 8011 and a handle 8012 vertically fixed to the pin shaft 8011; the pin shaft 8011 is movably installed at the four corner positions of the bottom plate 1 and the top plate 2 and can move along its own axis direction; one end of the pin shaft 8011 close to the end plate 3 passes through the pin hole 803 provided on the insertion plate 302 and extends into the pin positioning hole 804 provided on the upper mounting seat 201 or the lower mounting seat 102, and can be inserted into or withdrawn from the pin hole 803 and the pin positioning hole 804, so as to lock or unlock the end plate 3 with the bottom plate 1 and the top plate 2; the baffle 802 is slidably installed at the four corner positions of the bottom plate 1 and the top plate 2 and is located outside the pin 801, and is used to limit the handle 8012 in the locked or unlocked position, so as to limit the pin 801.

[0087] It should be noted that the handle 8012 and the pin shaft 8011 are preferably fixed by welding; taking the pin locking mechanism 8 installed on the bottom plate 1 as an example (the installation situation on the top plate 2 is the same), installation grooves for installing the pin locking mechanism 8 are reserved at the four corners of the bottom plate 1; a limiting block 811 is fixed in the installation groove, and is preferably fixed to the bottom plate 1 by welding. A middle positioning pin 805 is fixed at the middle position of the outer end face of the limiting block 811, and a first positioning pin 806 and a second positioning pin 807 are fixed on both sides. The three positioning pins are preferably screwed to the limiting block 811; a long hole 808 is provided on the baffle 802 and is sleeved on the middle positioning pin 805, and is blocked by the screw head of the middle positioning pin 805 and cannot be disassembled, but the baffle 802 can move horizontally on the middle positioning pin 805 along the direction of the long hole 808; a first card slot 809 and a second card slot 810 are provided at the lower edge of the baffle 802, and the first card slot 809 cooperates with the first positioning pin 806 to fix the baffle 802 in the locked position (as Figure 7The baffle 802 is horizontally moved to the position where the second card slot 810 cooperates with the second positioning pin 807, and then the baffle 802 is fixed at the unlocking position; when the baffle 802 is at the locking position and the unlocking position, one end of it can protrude outside the corresponding end of the limiting block 811; the bolt 801 can move along the axial direction of the locking pin 603 in the installation groove, and the operator moves the bolt 801 by operating the handle 8012; the handle 8012 is located on both sides of the limiting block 811 when the end plate 3 and the bottom plate 1 are locked and unlocked respectively.

[0088] It should be noted that when the container is in the unfolded state, the end of the locking pin 603 close to the end plate 3 passes through the bolt hole 803 of the end plate 3 (as Figure 3 shown) and then is inserted into the bolt positioning hole 804 of the lower mounting seat 102 of the bottom plate 1 to lock the end plate 3 and the bottom plate 1; at this time, the handle 8012 is located on one side of the limiting block 811, and the first card slot 809 of the baffle 802 cooperates with the first positioning pin 806 to fix the baffle 802 at the position as Figure 7 shown; and the end of the baffle 802 protruding from the limiting block 811 limits the handle 8012 at the current position; during the process of the container changing from the unfolded state to the folded state, the operator separates the first card slot 809 from the first positioning pin 806, moves the baffle to the middle position where the middle positioning pin 805 is close to the long hole 808, then raises the handle 8012 and moves it in the direction away from the end plate 3, so that the bolt 801 moves as a whole; when the handle 8012 moves to the other end of the limiting block 811, put down the handle 8012, and at this time the end of the locking pin 603 close to the end plate 3 is withdrawn from the bolt hole 803 and the bolt positioning hole 804; continue to move the baffle 802 along the long hole 808 until the second card slot 810 cooperates with the second positioning pin 807, and the end of the baffle 802 away from the end plate 3 limits the handle 8012 at the other side position of the limiting block 811; at this time, the end plate 3 and the bottom plate 1 are in the unlocked state.

[0089] In specific implementation, the bolt locking mechanism 8 can effectively and firmly lock and fix the end plate 3 and the bottom plate 1, which is time-saving, labor-saving, convenient and safe; by setting the installation groove, the bolt locking mechanism 8 will not protrude outside the container to affect the overall transportation size of the container; by setting the baffle 802, the handle 8012 can be fixed at the locking and unlocking positions to prevent the bolt 801 from accidentally moving out of the locked or unlocked state due to transportation bumps.

[0090] In one embodiment, as Figure 3 shown, hinge plates 301 are fixedly installed at the lower ends of both side edges of the end plate 3; one end of the hinge plate 301 away from the end plate 3 is hinged to a hinge shaft 101 fixedly installed at the lower end of the bottom plate 1 where the bolt 801 is located.

[0091] It should be noted that the articulated plate 301 is preferably fixed to the end plate 3 by welding; the articulated shaft 101 is preferably fixed to the bottom plate 1 by welding; one end of the articulated plate 301 away from the end plate 3 is provided with a through hole, which can cooperate with the articulated shaft 101 to achieve an articulated connection.

[0092] In specific implementation, when the container is in a folded state, the side plate 4 is below the end plate 3. Therefore, there should be a relatively high space between the end plate 3 and the bottom plate 1 after folding; by arranging the articulated plate 301, after the end plate 3 is folded, one end connecting the end plate 3 and the bottom plate 1 can be lifted by a certain distance, so as to meet the above requirements and achieve smooth folding.

[0093] In the embodiment provided by the present utility model, as Figure 9 shown, the sealing structure 10 includes a waterproof flap 1001; the waterproof flap 1001 is arranged on the outer end face of the frame of the top plate 2 and extends downward, and a first sealing strip 1002 is arranged on the inner surface.

[0094] It should be noted that the waterproof flap 1001 is preferably made of an aluminum alloy material plate, preferably fixed to the outer end face of the frame of the top plate 2 by a screw structure, and a sealing gasket 1003 is installed at the edge where it is in contact with the outer end face of the frame of the top plate 2; the first sealing strip 1002 is preferably fixed to the inner surface of the waterproof flap 1001 by a card slot method; in the unfolded state, the outer surfaces of the side plate 4 and the end plate 3 are in contact with the sealing strip, playing a sealing role.

[0095] In specific implementation, after the side plate 4 and the end plate 3 are turned outwards and unfolded, the upper ends abut against the inner end face of the waterproof flap 1001, which can effectively prevent rainwater and salt spray from entering the interior of the container from the joint with the top plate 2, playing a good waterproof effect.

[0096] In one embodiment, as Figure 10 、 Figure 11 shown, the sealing structure 10 further includes an H-shaped sealing strip 1004 and a second sealing strip 1005; the H-shaped sealing strip 1004 is respectively installed on the lower end faces of the bottom frames of the side plate 4 and the end plate 3 and between the two door panels 303; the second sealing strip 1005 is respectively installed on the end faces of the two side frames of the end plate 3 close to the side plate 4.

[0097] It should be noted that Figure 10 the H-shaped sealing strip 1004 between the two door panels 303 of the end plate 3 at the rear end of the container; Figure 11It is the H-shaped sealing strip 1004 between the bottom plate 1 and the side plate 4; the H-shaped sealing strip 1004 is preferably installed at the corresponding position through the self-borne card slots, and the second sealing strip 1005 is fixed at the corresponding position by opening card slots or bonding on the plate. The present utility model preferably adopts the fixing method of opening card slots. The above installation method can realize the replacement of the sealing strip; the first sealing strip 1002, the H-shaped sealing strip 1004 and the second sealing strip 1005 are all preferably made of silicone rubber material; silicone rubber is a high-performance and all-round sealing material, with excellent sealing performance, and at the same time has extremely high high-temperature resistance and anti-aging performance; silicone rubber can still maintain its original elasticity and mechanical properties in a high-temperature environment, and performs better than other rubber materials at high temperatures; and silicone rubber has outstanding ozone resistance and weather aging resistance, and can maintain its unique use elasticity, ozone resistance, weather resistance, etc. within the working temperature range of -70 to 260 °C, and is suitable for manufacturing sealing products in high and low temperature environments.

[0098] In specific implementation, setting the H-shaped sealing strip 1004 and the second sealing strip 1005 can effectively seal between the movable connecting parts; especially in the unfolded state of the container, it can better prevent the intrusion of external impurities such as dust and rain.

[0099] Such as Figure 12 and Figure 13 shown, the working process of the lightweight folding sealed container for folding and unfolding is as follows:

[0100] In the unfolded state, the operator unlocks the buckle locking mechanism 6 of the two side plates 4 of the container, and then unlocks the pressing plate locking mechanism 7 that locks the side plate 4 and the end plate 3, and pushes the two side plates 4 inward. The side plates 4 slowly tilt towards the inside of the container under the damping action of the hinge mechanism 5 until both side plates 4 are horizontal with the bottom plate 1; the operator then unlocks the pin locking mechanism 8 between the end plate 3, the bottom plate 1 and the top plate 2, and then uses a forklift or other lifting equipment to lift the top plate 2 and then put it down until both end plates 3 and the top plate 2 fall on the bottom plate 1 and are parallel to the bottom plate 1. At this time, the folding operation of the container is completed; as Figure 14 shown, the folded containers can be stacked and placed;

[0101] The operation sequence of the unfolding process is opposite to that of the folding process. First, lift the top plate 2 and then put it down, so that the end plate 3 is unfolded to be perpendicular to the bottom plate 1, and lock the pin locking mechanism 8; lift both side plates 4 to be perpendicular to the bottom plate 1, and sequentially lock the pressing plate locking mechanism 7 and the buckle locking mechanism 6 to complete the unfolding operation.
