Description

Technical Field

[0001] The invention belongs to the field of loaders for transport, and in particular relates to a loading box. Background Art

[0002] There are human living areas (for example, stationed troops) in remote areas such as mountains, deserts, and villages. The roads in these remote areas are complex and vehicles cannot pass through. The distribution of materials such as fuel usually relies on manual transportation, which has a long distribution distance, heavy distribution tasks, and huge physical consumption of distribution personnel. In order to reduce the labor intensity of existing distribution personnel, (powered) exoskeletons have been developed and designed in the prior art (for example, "a wearable lower limb load-bearing exoskeleton with active and passive switching" disclosed in announcement number CN112999018A). After wearing the exoskeleton, the distribution personnel can reduce the load pressure, increase the power of load and travel, and greatly reduce the intensity of distribution work.

[0003] The existing loading box (for example, fuel tank) for loading materials is shown in the technical solution of "a field mobile modular combined fuel tank group" disclosed in the announcement number CN211770271U, which includes:

[0004] The fuel tank module, pump module, filtration and separation module and refueling module are connected in sequence through pipelines: the fuel tank module includes a jumper telescopic hose and a multi-layer fuel tank group stacked in a building block style, each layer of the fuel tank group includes a number of modular fuel tanks, the modular fuel tanks are provided with a three-way connecting hose, the three-way connecting hose is used for sequentially connecting the modular fuel tanks on the same layer to form an oil circuit, and the jumper telescopic hose is used for sequentially connecting the oil circuits of the multi-layer fuel tank group end to end; the pump module includes a first box body, the first box body is provided with an electric refueling pump; the filtration and separation module includes a second box body, the second box body is used to filter the inflowing oil and separate the oil and water; the refueling module includes a bracket, the bracket is provided with an aircraft pressure connector and a refueling gun with a flow meter, and a reel for winding the tape of the refueling gun with a flow meter.

[0005] However, the above-mentioned "a field mobile modular combination fuel tank group" still has the shortcomings that it focuses on modular design to improve the convenience of refueling and using the fuel tank, but it is still not convenient to cooperate with the exoskeleton to achieve loading and distribution.

[0006] Based on this, the applicant considered designing a loading box that is easy to use with an exoskeleton. Summary of the invention

[0007] In view of the above-mentioned deficiencies in the prior art, the technical problem to be solved by the present invention is: how to provide a loading box that is easy to be used with an exoskeleton.

[0008] In order to solve the above technical problems, the present invention adopts the following technical solutions:

[0009] The loading box comprises a box body, and the box body is provided with a loading inlet and / or a pouring outlet; the characteristic is that the box body is also provided with a locking matching structure for loading, and the locking matching structure for loading is used to be fixedly connected with the locking structure on the supporting mechanism.

[0010] Compared with the prior art, the loading box of the present invention has the following advantages:

[0011] There is no need to bundle the loading box, that is, it can be directly fixedly connected with the locking structure on the supporting mechanism of the exoskeleton through the loading locking matching structure, so that the loading box is easier to install, fix and disassemble on the exoskeleton.

[0047] The present invention will be further described in detail below in conjunction with the accompanying drawings.

[0048] The first embodiment, such as Figures 1 to 12 As shown:

[0049] The loading box comprises a box body A, which is provided with a loading inlet 1 and / or a pouring outlet 2; the box body A is also provided with a locking matching structure for loading, and the locking matching structure for loading is used to be fixedly connected with the locking structure on the supporting mechanism.

[0050] The loading locking matching structure on the box body A includes a locking groove C and at least one plug-in limiting protrusion 8, and the locking groove C and the plug-in limiting protrusion 8 are both arranged on the bottom surface of the box body A; the plug-in limiting protrusion 8 is an L-shaped structure as a whole when viewed from above, and a reinforcing rib block 81 is connected to the position adjacent to the lower end surface between the two side surfaces where the inner angle of the L-shaped structure is located;

[0051] The support mechanism includes a support plate 13, and the locking structure on the support plate 13 includes a locking block 15 and plug-in limit recessed holes E that are arranged in a one-to-one correspondence with the number and position of the plug-in limit protrusions 8, each of the plug-in limit recessed holes E is located on the upper surface of the support plate 13, and the plug-in limit recessed holes E are in a b-type structure as a whole when viewed from above, and the D portion of the b-type structure is just enough for the plug-in limit protrusions 8 to be filled and inserted, and the side surface of the I portion of the b-type structure has an abutment block E that can be vertically abutted by the reinforcing rib block 81, so as to realize the limited matching connection between the box body A and the support plate 13 in the vertical direction;

[0052] The locking block 15 is used to align and insert into the locking groove C after the box body A and the support plate 13 are connected in a vertical limiting manner to achieve lateral limiting positioning and locking of the box body A and the support plate 13, and is also used to withdraw from the locking groove C to achieve unlocking.

[0053] In practice, the support plate 13 is provided with a mounting portion for mounting on the back side of the exoskeleton, and the mounting portion can be a pair of inserting tubes arranged on the side of the support plate 13 and for the mounting shaft on the exoskeleton to be inserted. In this way, the support plate 13 can be turned over into a flat plate when needed and used for fixing the loading box; it can also be conveniently folded up when not in use.

[0054] During implementation, a mounting groove for the support plate to be inserted is provided in the middle of the length direction of the bottom surface of the box body A. This can achieve: relatively accurate positioning between the box body and the support plate during assembly, ensuring that the box body can be loaded on the support plate more quickly.

[0055] During implementation, it is preferred that the plug-in limit protrusions 8 are at least two pairs symmetrically arranged in the left-right direction, so that the plug-in limit protrusions 8 and the corresponding plug-in limit recesses E can be connected reliably after being plugged in, ensuring the stable installation of the loading box on the exoskeleton.

[0056] The loading locking fitting structure arranged on the box body A, the locking block 15 arranged on the support plate 13 and the plug-in limiting recessed hole E corresponding one-to-one to the plug-in limiting protrusion 8 have the advantages of simple and reasonable structure and easy processing and manufacturing, and the vertical and horizontal upper limit connection effects are reliable, and the locking effect is also reliable, ensuring that the exoskeleton and the loading box can be reliably connected during the transportation process, thereby ensuring the smooth transportation.

[0057] The locking structure on the support plate 13 further includes a stopper drive control mechanism, and the stopper drive control mechanism includes a connecting rod 14, a tension spring 16 and a pull ring 17;

[0058] The connecting rod 14 is an elongated structure as a whole and its length direction is parallel to the plate surface of the support plate 13. The connecting rod 14 is slidably inserted on the mounting protrusion protruding downward on the lower plate surface of the support plate 13. The side of the connecting rod 14 is fixedly connected with the locking block 15 protruding radially outward. One end of the connecting rod 14 is connected to one end of the tension spring 16, and the other end of the tension spring 16 is connected to the connecting protrusion protruding downward on the lower surface of the support plate 13. The other end of the connecting rod 14 is connected to the pull ring 17.

[0059] After adopting the above-mentioned block drive control mechanism, the locking block 15 can be conveniently controlled to realize the locking and unlocking between the loading box and the support plate 13, specifically:

[0060] A. Locking and installation process of the loading box and the exoskeleton (support plate 13)

[0061] During the installation and connection process of the loading box and the exoskeleton, first align the four insertion and limiting protrusions 8 on the bottom of the loading box with the four insertion and limiting recesses E on the support plate 13 of the exoskeleton. When the bottom of the loading box is completely fitted with the support plate 13 of the exoskeleton, push the loading box along the rotation axis of the support plate 13 of the exoskeleton. At this time, the loading box only has the degree of freedom along the direction parallel to the installation surface of the support plate 13. Pull and rotate the pull ring 17, and the pull ring 17 drives the locking block 15 fixed on the connecting rod 14 to rotate 90 degrees. The locking block 15 is in a vertical state and stuck in the recessed cavity at the bottom of the loading box. At this time, the loading box is completely fixed on the support plate 13 of the exoskeleton.

[0062] B. Loading box and exoskeleton disassembly process

[0063] The disassembly process of the loading box and the exoskeleton is the opposite of the locking installation process.

[0064] First, pull the pull ring 17 and rotate it to rotate the connecting rod 14, driving the locking block 15 to rotate to a horizontal state. After pulling it backward along the mounting surface of the support plate 13 to a stop point, the loading box can be taken out upward, so that the insertion limit protrusion 8 at the bottom of the loading box is separated from the insertion limit concave hole E on the support plate 13 of the exoskeleton, and the loading box and the exoskeleton are disassembled.

[0065] When implemented, the locking structure is located at the bottom of the support plate 13 of the exoskeleton, and the structure is encapsulated in the baffle 18 by screws 19.

[0066] During implementation, the box body A is also provided with a steel shaft 6, which can play a role in binding and fixing.

[0067] During implementation, the side surfaces of the loading box are provided with outwardly convex reinforcement structures (9, 10), which play a role in strengthening the structural strength of the oil tank.

[0068] The box body A is a cubic structure as a whole; it also includes a stacking stabilization structure, and the stacking stabilization structure includes a stacking lock plate 4 and a lock ear 5;

[0069] The stacking lock plate 4 is a cross-shaped structure as a whole when viewed from above. The upper surfaces of the four protruding parts of the cross-shaped structure have upwardly convex plug-in bosses 405, and the lower surface of the middle part of the cross-shaped structure is provided with an elastic reset structure.

[0070] The four inner corners of the upper surface of the box body A are each provided with a quarter-circle notch for stable stacking, and the locking ear 5 is protruded outwardly at the upper end of the middle part of the arc-shaped side surface of the notch for stable stacking, and the locking ear 5 is vertically penetrated with a socket for the insertion boss 405 on the stacking lock disk 4 to be aligned and inserted.

[0071] By adopting the above-mentioned stacking stabilization structure, four loading boxes in a group can be quickly arranged and locked by using the stacking lock plate 4 and the lock ear 5 to ensure the neatness and stability of the stacking, thereby ensuring more stable transportation and stacking. The specific stacking locking operation is as follows:

[0072] The stacking lock plate 4 is placed into a circular groove formed by the quarter-circle stable stacking notches of each of the four adjacent loading boxes, and the fast stacking lock plate 4 is rotated so that its four plug-in protrusions 405 are plugged into the corresponding plug holes on the four lock ears 5 to form a limit fit.

[0073] In practice, it is preferred that the upper surface of the stacking lock disk 4 is further provided with an upper convex portion 401, which can not only abut against the lock ear 5 by the side to rotate and position, but also enhance the overall structural strength of the stacking lock disk 4 to ensure structural reliability.

[0074] The elastic reset structure includes a base 403, a cover plate 402 and a compression spring 404. The lower surface of the middle part of the cross-shaped structure of the stacking lock plate 4 is convexly formed with a cylindrical sleeve portion. The cover plate 402 is an annular structure as a whole and is slidably sleeved on the sleeve portion. The lower end of the outer side surface of the sleeve portion has an axial limiting flange convex outward in the radial direction.

[0075] The cover plate 402 is a cover-shaped structure as a whole, with the opening facing upward and the inner side of the opening covering and connected with the circumferential edge of the cover plate 402;

[0076] The compression spring 404 is disposed inside the cover plate 402 and has two ends abutting between the inner side surface of the cover plate 402 and the lower end surface of the sleeve portion.

[0077] During implementation, the compression spring 404 and the stacking lock plate 4 are installed between the base 403 and the cover plate 402 by bolts and nuts. It is easy to load the compression spring 404 into the base 403 and the cover plate 402 inside.

[0078] During implementation, it is preferred that a convex ridge for twisting is formed on the middle portion of the upper surface of the stacking lock disk 4, so that it is convenient for gripping operation during twisting.

[0079] The elastic reset structure of the stacking lock disk 4 can be compressed under the action of pressing, and the downward pressure is maintained and the stacking lock disk 4 is turned. Under the action of the restoring force of the compression spring 404, the plug-in boss 405 and the socket on the lock ear 5 complete the limiting cooperation, which can realize the quick lock fixation of stacking multiple loading boxes or the coordinated installation of a single loading box during carrying.

[0080] When removing the stacking lock disk 4, the stacking lock disk 4 is also pressed down and rotated in the opposite direction. When the plug-in boss 405 is disengaged from the insertion hole on the lock ear 5, the stacking lock disk 4 is separated from the oil tank body or the stacking oil tank.

[0081] Therefore, the stacking lock plate 4 has a reasonable structure, is easy to assemble, and is convenient and reliable to operate.

[0082] Among them, the side of the box body A is provided with a placement groove B for placing the stacking lock disk 4, and the placement groove B is a circular groove structure as a whole. A plug-in protrusion is protruded radially inward at a position adjacent to the notch on the side of the placement groove B, and two or four plug-in protrusions are evenly spaced in the circumferential direction of the placement groove B. Each of the plug-in protrusions is provided with a through hole that penetrates along the axial direction, and the through hole is used for the insertion boss 405 on the stacking lock disk 4 to align and insert to achieve snap-on limiting.

[0083] In this way, a stacking lock disk 4 can be placed on each loading box, so that the stacking lock disks 4 on the loading boxes stacked in groups of four are more abundant, avoiding the situation where the loss of a single stacking lock disk 4 affects the reliable stacking of batch loading boxes.

[0084] The side of the box body A on which the placement groove B is provided is the side for placing the stacking lock disc 4, and the side for placing the stacking lock disc 4 is provided with a ring-shaped stacking alignment groove 7 at the periphery of the placement groove B;

[0085] An annular stacking alignment protrusion 10 is provided on the outer surface of the shell of the box body A, which is opposite to the side for placing the stacking lock disk 4. The stacking alignment protrusion 10 on one box body A can be inserted into the stacking alignment groove 7 on another box body A to achieve limited docking.

[0086] After the above-mentioned stacking alignment grooves 7 and stacking alignment protrusions 10 are provided on a single box body A, it can not only play the role of a reinforcing rib and enhance the structural strength of the two opposite side faces and the structural strength of the box body A, but also enable the two box bodies A to be accurately aligned and positioned by inserting the stacking alignment protrusions 10 on one box body A into the stacking alignment grooves 7 on the other box body A, better ensuring the neatness and reliability of stacking.

[0087] Among them, the upper surface of the box body A is provided with the large-diameter pouring inlet and the small-diameter pouring outlet 2 at intervals.

[0088] The advantage of adopting the above-mentioned large-diameter pouring inlet is that it is easier to pour materials into the box body A; the advantage of adopting the small-diameter pouring outlet 2 is that it is easier to align with the receiving port when pouring materials, effectively avoiding waste of materials due to seepage.

[0089] Among them, the lower surface of the box body A is provided with two vertical stacking positioning slots that are opposite to the pouring inlet and the pouring outlet 2 and match in shape and size.

[0090] After adopting the structure of the box body A with the above-mentioned vertical stacking positioning slots, when stacking vertically, the vertical stacking positioning slots on the lower surface of the upper box body A can be sleeved on the corresponding pouring inlet and pouring outlet 2 of the lower box body A, realizing neat stacking and positioning in the vertical direction and limiting in the horizontal direction, so as to better ensure the neatness, consistency and reliability of the loading boxes stacked in the height direction.

[0091] Among them, the upper surface of the box body A is rectangular, and the pouring inlet and the pouring outlet 2 are located at both ends of the rectangular length direction of the upper surface of the box body;

[0092] At the middle position of the length direction of the upper surface of the box body A, a handle 3 in the shape of a工字 (I-shaped) in the top view direction is also fixedly provided, and the handle 3 has a 冂-shaped structure when viewed in the width direction of the upper surface of the box body A.

[0093] The above-mentioned handle 3 not only has the advantages of simple structure and light weight, but also has many connection points with the box body A, so as to ensure the reliable connection between the handle 3 and the box body A; and the middle part of the I-shaped handle 3 in the top view direction is convenient for a single person to lift, and the parts at both ends of the I-shaped handle and in the 冂-shaped structure when viewed in the width direction are convenient for two or more people to lift the loading box at the same time, so it is more convenient and flexible to use.

[0094] The second embodiment is as Figures 13 to 23 shown:

[0095] The difference between this embodiment and the first embodiment is:

[0096] A locking cylinder 131 is vertically penetrated in the middle of the support plate 13, and a locking protrusion 132 is formed on the inner wall of the locking cylinder 131, and four locking protrusions 132 are evenly spaced in the circumferential direction of the locking cylinder 131;

[0097] The locking structure on the support plate 13 includes a locking disk 4 for loading and locking, and the locking disk 4 for loading and locking is a four-pointed star structure as a whole in a top view direction, and the outer diameter of the circumscribed circle of the four protruding parts of the four-pointed star structure matches the inner diameter of the locking cylinder 131, and each protruding part of the four-pointed star structure has a slot 406 that passes through along the tangent direction of the circumscribed circle near the outer end and adjacent to the upper surface; the outer end of each protruding part of the four-pointed star structure and the position adjacent to the lower surface are convexly formed with a reinforcing rib plate 407, and the middle position of the upper surface of the reinforcing rib plate 407 has a convex plug-in boss 405, and the middle lower surface of the four-pointed star structure is provided with an elastic reset structure;

[0098] The loading locking matching structure on the box body A includes a locking circular groove and a locking circular ring plate G arranged on the bottom surface of the box body A, the inner diameter of the locking circular groove matches the inner diameter of the locking cylinder 131, and the depth of the locking circular groove is less than the thickness of the loading locking lock disk 4 in the natural state; the locking circular ring plate G is coaxially fixed at the notch of the locking circular groove, and the inner side of the locking circular ring plate G has a protrusion G01 protruding from the side wall of the locking circular groove, and a locking structure is arranged on the protrusion G01, which is an axially through-hole (not shown in the figure) or a limiting groove G02 is arranged for the plug-in boss 405 to enter and limit along the circumferential direction;

[0099] Press the elastic reset structure of the loading locking lock disk 4, and then rotate the loading locking lock disk 4 so that the slot 406 on each protruding part of the loading locking lock disk 4 can be sleeved on the protrusion G01 of the locking ring plate G fixed on the box body A, and the plug-in boss 405 of the loading locking lock disk 4 can enter the locking structure of the locking ring plate G fixed at the bottom of the box body A to achieve locking.

[0100] After adopting the above-mentioned support mechanism, the loading locking lock disk 4 and the loading locking matching structure on the box body A, the box body A can be locked and fixed on the support mechanism through the loading locking lock disk 4, which is very convenient to operate.

[0101] The side surfaces of the protruding parts of the four-pointed star-shaped structure of the above-mentioned loading and locking lock disk 4 adjacent to the reinforcing rib plate 407 in the circumferential direction also serve as rotation limiting surfaces 408. When the rotation limiting surfaces 408 are in contact with the protrusion G01 on the locking ring plate G, the loading and locking lock disk 4 can be rotated into position before being locked. Then, after releasing the hand and eliminating the compression on the elastic reset mechanism, the locking function of the loading and locking lock disk 4 is realized.

[0102] During implementation, the stacking lock disk and the loading and locking lock disk 4 have the same structural dimensions, that is, the stacking lock disk and the loading and locking lock disk 4 can be used interchangeably.

[0103] The advantage of such a design is that the stacking lock disk or the loading locking lock disk 4 installed on each box A can not only meet the requirements for locking a single box A and loading it onto the exoskeleton, but also meet the requirements for stacking and fixing multiple boxes A, and has better versatility and ease of use.

[0104] During implementation, the locking protrusion 132 formed on the inner wall of the locking cylinder 131 is in an isosceles trapezoidal structure as a whole, and the side of the isosceles trapezoidal structure close to the inner wall of the locking cylinder 131 is the lower base.

[0105] The connection surface between the locking protrusion 132 and the locking cylinder 131 is larger and the connection strength is higher; at the same time, the locking protrusion 132 also acts as a reinforcing rib to improve the structural strength and durability of the locking cylinder 131, thereby ensuring that the box A is reliably locked and supported.

[0106] During implementation, the locking protrusion 132 is provided with a waist-shaped hole for observation that penetrates along the axial direction of the locking cylinder 131 .

[0107] The setting of the above-mentioned waist-shaped hole for observation can not only help reduce the material and weight, but also facilitate the observation of the position of the plug-in boss 405 during the process of rotating the loading and locking lock disk 4, so as to facilitate timely observation of the plug-in boss 405 in place and alignment, and quickly perform the locking operation.

[0108] During implementation, a plurality of reinforcing ribs distributed radially are connected between the lower surface of the support plate 13 and the outer side surface of the locking cylinder 131 .

[0109] In this way, the thickness and material of the support plate 13 can be reduced while the structural strength of the entire support plate 13 can be greatly improved, thereby ensuring that the support plate 13 structure has long-term reliability.

[0110] The bottom of the box body A is provided with a loading groove, the loading groove runs through the box body A in the thickness direction, and the groove width of the loading groove is consistent with the width of the support plate 13;

[0111] The end of the support plate 13 adjacent to the exoskeleton in the length direction is the mounting end. A limit stopper 133 is convexly formed on the upper plate surface of the mounting end of the support plate 13. The limit stopper 133 is used to abut against the outer side surface of the box body A for limiting position.

[0112] With the above structure, the box A can be accurately and quickly guided and positioned in the X direction (width direction) and Y direction (length direction) of the support plate 13, ensuring that the lock plate 4 for subsequent loading and locking is quickly aligned and locked. Specifically:

[0113] The "groove width of the loading groove is consistent with the width of the support plate 13" so that the support plate 13 can accurately fall into the loading groove and complete the guidance and limitation of the box A in the X direction (width direction) of the support plate 13; the above-mentioned "structure in which the limit block 133 abuts against the outer surface of the box A" can be used to achieve the limitation and positioning of the box A in the Y direction (length direction) of the support plate 13.

[0114] A process groove penetrating in the width direction is formed in the middle of the length direction of the upper surface of the box body A; a handle 3 is provided at the process groove.

[0115] During implementation, the process groove is fixedly connected with a handle 3 between two side walls along the length direction of the upper surface of the box body A, and preferably the handle 3 and the box body A are an integrally formed structure. In this way, the box body A structure with the handle 3 can be directly processed by the blow molding process, thereby improving the processing and production efficiency of the box body A; at the same time, the integral molding of the handle 3 and the box body A can also further improve the structural strength of the top of the box body A, and better ensure the reliability of the quality of the box body A.

[0116] During implementation, the handle 3 is in a shape of a circle when viewed along the width direction of the upper surface of the box body A; and three handles 3 are arranged at intervals along the length direction of the process groove.

[0117] The arrangement of the three handles 3 can not only multiply the structural strength of the connection between the handles 3 and the box body A and the top of the box body A, but also facilitate two people to carry the box collaboratively through the two outer handles 3. In addition, it is also convenient for a single person to carry the box with one hand or both hands, which is more practical.

[0118] A third embodiment, not shown in the figure:

[0119] The difference between this embodiment and the first embodiment is that the locking fitting structure for loading on the box body A is arranged on any side surface of the box body A in the transverse circumferential direction.

[0120] A fourth embodiment, not shown in the figure:

[0121] The difference between this embodiment and the first embodiment is that the pin head on the elastic latch constitutes the locking block 15, and the rest of the elastic latch constitutes the block driving control mechanism.

[0122] The advantages of the loading boxes of the above four embodiments are:

[0123] There is no need to bundle the loading box, that is, it can be directly fixedly connected with the locking structure on the supporting mechanism of the exoskeleton through the loading locking matching structure, so that the loading box is easier to install, fix and disassemble on the exoskeleton.

[0124] The loading box of the present invention also has the advantages of being easy to stack neatly and improving the reliability of stacking during transportation.

[0125] The above are only preferred implementations of the present invention. It should be pointed out that a number of modifications and improved technical solutions made by those skilled in the art without departing from the technical solution should also be deemed to fall within the scope of protection required by the claims.
