Description

Container liquid bag soft structure limiting device for long-distance transportation

Technical Field

The invention relates to the technical field of container accessories, in particular to a limiting device for a soft structure of a liquid bag of a container for long-distance transportation.

Background

A container is a group tool which can load packaged or unpackaged goods and is convenient to load, unload and carry by mechanical equipment. The container transportation has the advantages of high standardization, good sealing performance, low damage rate, intensification, large scale, shift, low cost, good quality and the like, so that the safety and the efficiency of the cargo transportation are greatly improved.

The container liquid bag is a soft packaging container which is placed in a container and used for storing and transporting various non-dangerous liquid cargos, but the container liquid bag is inconvenient to fill in practical use: because the liquid bag is the software, in addition the liquid bag filling process, need open the chamber door of container, the container only has three lateral wall can provide spacingly to the liquid bag this moment, and the liquid bag is close to container open-ended one side and can outwards bulge for the chamber door can't normally be closed, even only open a chamber door, also can lead to the liquid bag outwards to bulge.

In order to solve the problem that a liquid bag of a container protrudes outwards from an opening of the container in the filling process, the patent publication with the Chinese patent publication number of CN113895807A provides a limiting part for the container, the limiting part comprises a baffle plate, a first lug and a second lug are respectively arranged on two sides of the baffle plate, the first lug and the second lug can be detachably connected in a reserved groove of the container, so that the container forms the limit on the limiting part in the front-back direction and the left-right direction, the back of the baffle plate is abutted against the liquid bag of the container to limit the liquid bag of the container, and a reserved hole is arranged on the lower side of the baffle plate to facilitate an operator to connect a drain port of the liquid bag through a pipeline.

However, the above-mentioned limiting part for container has the problem of inconvenient use, especially for the case that the liquid bag adopts two pipe joints as filling opening and drain opening respectively, this limiting part can bring the following trouble:

1. in order to facilitate installation, the height of a single limiting part cannot be set too large, so that a plurality of limiting parts need to be installed in a superposed manner, before the limiting parts are installed in the superposed manner, the infusion pipeline must be connected with the filling opening, otherwise, the problem that the filling opening cannot be connected due to too high superposed height occurs; however, the installation position of the limiting member is required to be accurately corresponding to the reserved groove of the container, the installation of the limiting member is hindered by the existence of the infusion tube, and particularly when the limiting member at a higher position is required to be installed, the installation position is too high, the requirement on the position precision is high, and the obstruction of the infusion tube is caused, so that the three factors work together, and the installation of the limiting member is extremely difficult.

2. The distance between the left end and the right end of the opening of the container is actually shorter than the distance between the bottoms of the reserved slots at the two sides of the container, so that the overall length of the limiting part is often longer than the distance between the left end and the right end of the opening of the container, and when the limiting part is installed, the limiting part needs to be arranged in an inclined mode firstly, and then the limiting part can be moved to the position corresponding to the reserved slot; therefore, only when the distance between the top of the container and the current top limit part is higher than the overall height of the single limit part, the limit parts can be continuously stacked and installed, so that the maximum stacking height of the limit parts (namely the maximum limit height of the liquid bag) is much lower than the opening height of the whole container, the filling capacity of the liquid bag of the container is limited actually, and more container storage space is wasted.

Detailed Description

The present invention will be further described with reference to the accompanying drawings and the detailed description, and it should be noted that any combination of the embodiments or technical features described below can be used to form a new embodiment without conflict.

Referring to fig. 1-12, the embodiment of the invention provides a container liquid bag soft structure limiting device for long distance transportation, which comprises a plurality of layers of limiting members 1 nested in sequence from outside to inside, wherein each limiting member 1 is provided with a baffle 11 for limiting a liquid bag;

Specifically, each limiting member 1 further has side plates 12 located on the left and right sides of the baffle plate 11; each limiting piece 1 is also provided with a bottom plate 13 positioned at the bottom end of the baffle plate 11; the back of the baffle 11 is used for limiting the container liquid bag; a containing space 10 is defined by the front surface of the baffle plate 11, the inner side surface of the side plate 12 and the top surface of the bottom plate 13, and the limiting piece on the inner layer is assembled in the containing space of the limiting piece on the outer layer;

further, the top end of the baffle plate 11 and the top end of the side plate 12 enclose a top opening 101, and the front end of the side plate 12 and the front end of the bottom plate 13 enclose a front opening 102 located in the front direction of the baffle plate 11.

Compared with the prior art, the container liquid bag soft structure limiting device for long-distance transportation has the following advantages that:

(1) the invention provides a limiting device of a liquid bag soft body structure of a container for long-distance transportation, which comprises a plurality of layers of limiting parts which are nested in sequence from outside to inside, wherein in the installation process, the (left and right ends of the) limiting part at the outermost layer is assembled to a reserved groove of the container, so that the container forms the front-back and left-right limiting of the limiting part at the outermost layer, and in the adjacent two layers of limiting parts, the limiting part at the outer layer forms the front-back and left-right limiting of the limiting part at the inner layer, so that once the limiting part at the outermost layer is installed, the container also forms the front-back and left-right limiting of all the limiting parts, and the front-back and left-right positioning operation of the limiting part at the inner layer is not needed, therefore, the existence of an infusion pipeline basically has no interference effect, and the installation difficulty is greatly reduced.

(2) In addition, after the outermost limiting part is installed, one or more layers of limiting parts in the outermost layer are moved upwards, so that the limiting height of the whole limiting device on the liquid bag can be increased, for the upwards-moving limiting part, (the left end and the right end of) the limiting part can be connected with the reserved groove to lock the limiting part (namely, limit the limiting part in the vertical direction), or the limiting part is connected with other locking limiting parts, so that the locking effect is achieved; and adjacent two-layer locating part between be the sliding fit from top to bottom, so whole stop device can be stepless regulation to the spacing height of container liquid bag in fact, as long as the quantity of locating part is enough, spacing height reaches the roof of container and is feasible completely, consequently helps the filling capacity of make full use of container liquid bag to and improve the utilization ratio of container storage space.

(3) Of course, for container bags with a small filling capacity, it is obvious that it is not necessary to have a too high limit height; however, if the limiting members which need to be installed in a superposed manner in the prior art are adopted, the problem that the limiting height is difficult to be suitable easily occurs, because the minimum variation unit of the limiting height in the prior art is the overall height of a single limiting member, such a situation may occur: at the more locating part that superposes of current spacing height, then spacing height is too high, is difficult to with infusion pipeline and liquid bag filling mouth separation, nevertheless superposes this locating part less, then spacing height crosses lowly, can't play good limiting displacement to the liquid bag. However, the characteristic that the container liquid bag soft structure limiting device for long-distance transportation can be adjusted in a stepless manner is utilized, and the problem that the limiting height is difficult to adapt can be well solved; the operator only needs to roughly calculate the relation between the filling capacity and the expansion height of the container liquid bag according to the bottom surface area of the container, and adjust the limiting height of the limiting device to be slightly higher than the maximum expansion height of the limiting device.

Next, the partial structural designs of the soft structure limiting device of the liquid bag of the container for long-distance transportation will be described.

Preferably, the lower part of the baffle 11 is provided with a preformed hole 111, and when the two adjacent layers of limiting members are overlapped, the preformed holes of the two layers of limiting members correspond to each other in position; the main function of the reserved hole 111 is to facilitate the worker to connect the drain port of the container liquid bag through a pipeline.

First, it should be understood that due to the physical characteristics of the liquid cargo, the pressure it exerts on the stop device increases from top to bottom, and therefore it is desirable to increase the stiffness of the stop in the lowermost position. The method can be operated as follows: for example, assuming that the whole limiting device has three limiting parts, and only two layers are needed to meet the requirement of limiting height, the limiting parts are arranged in sequence from outside to inside, then the first layer of limiting part is the outermost limiting part and is fixed, the second layer of limiting part does not move upwards so as to be overlapped with the first layer of limiting part, and only the third layer of limiting part moves upwards, so that the positions of the limiting parts of the first layer and the second layer are relatively low and relatively large under the pressure of the liquid bag, but the rigidity can be just increased by overlapping the limiting parts; for another example, if the whole limiting device has six layers of limiting members, and only three layers are needed to meet the requirement for limiting height, then three layers of limiting members can be allocated to the lowest position, two layers of limiting members can be allocated to the middle position, and only one layer of limiting member can be allocated to the highest position. Therefore, the soft structure limiting device for the liquid bag of the container for long-distance transportation can reasonably distribute the layer number of the limiting parts according to the height position so as to achieve better limiting effect.

When the number of layers of the limiting parts is reasonably distributed, the limiting parts with multiple layers are always superposed at the lowest position, so that the problem that the drainage port cannot be connected by a pipeline due to mutual interference when the limiting parts with multiple layers are superposed together is solved, and the structural design corresponding to the positions of the reserved holes is adopted. This structural design makes the operation personnel can also make things convenient for the pipeline connection drain opening (drain opening also is the filling mouth under the circumstances a bit simultaneously) for the operation personnel when the rational distribution locating part number of piles.

Furthermore, it should be understood that the operator may adjust the layer number distribution of the position limiting element at each height position according to the actual transportation environment and the transportation tool, and does not need to process the layer number distribution according to the above distribution mode.

Preferably, the upper part of the baffle 11 is provided with a reserved notch 112, the opening of the reserved notch 112 faces upwards, and when two adjacent layers of limiting members are overlapped, the positions of the reserved notches of the two layers of limiting members are corresponding; the reserved notch 112 is mainly used for placing a transfusion pipeline and plays a certain limiting role in horizontal moving of the transfusion pipeline; or when the limiting height is close to or reaches the top of the container, the operator can conveniently detach the infusion pipeline from the liquid bag filling opening; because the highest position can be distributed with a plurality of layers of limiting parts, the structural design corresponding to the position of the reserved notch is adopted.

Preferably, for how to realize the up-and-down sliding fit, the structural design can be adopted: for two adjacent layers of limiting members, the outer layer of limiting member has a linear boss 121, the linear boss 121 is located on the inner side surface of the side plate 12 and is arranged along the height direction of the side plate 12, the inner layer of limiting member has a linear sliding chute 122, and the linear sliding chute 122 is located on the outer side surface of the side plate 12 and is arranged along the height direction of the side plate 12; the linear boss 121 of the limiting member on the outer layer is in sliding fit with the linear sliding chute 122 of the limiting member on the inner layer; the side plate of the limiting piece at the innermost layer is also provided with a linear boss.

In fact, in the embodiment of the present invention, the position-limiting members of the other layers, except the position-limiting member of the outermost layer, have the linear bosses and the linear sliding grooves, although theoretically, the position-limiting member of the innermost layer does not need the linear bosses, which may result in that the number of the position-limiting members of the whole position-limiting device cannot be further increased.

Preferably, for the outermost position limiting member, the outer side surface of the side plate 12 is provided with a connecting part 123, and the connecting part 123 is used for being detachably assembled into a preformed groove of the container, so that the container forms the front-back and left-right limiting of the outermost position limiting member. The connecting parts 123 on the left side and the right side are different in form and structure, the structural design of the first lug and the second lug in the prior art is referred to, the specific installation principle of the connecting parts 123 can refer to the prior art, and the connecting parts 123 provide a method for installing the limiting part on the outermost layer.

For how to lock the position limiting element inside the outermost layer and needing to move upwards, the structure design can be referred to: for each limiting member in the outermost layer, the linear boss 121 of the side plate 12 corresponds to the linear chute 122 in position, a plurality of threaded through holes 120 are formed in the linear boss 121 and sequentially arranged from top to bottom, and the threaded through holes 120 are communicated with the linear chute 122; for two adjacent layers of limiting members in the outermost layer, when the two limiting members are overlapped, the axes of the threaded through holes of the two limiting members are overlapped, and the threaded through holes overlapped on the same axis can form threaded fit with the same locking bolt 3; wherein the locking bolt 3 is intended to pass through a single or a plurality of threaded through holes to extend into the pregroove 2 of the container and to abut against the bottom 21 of the pregroove 2.

In the embodiment of the invention, the limit part 1 in the outermost layer is connected with the preformed groove 2 of the container by using the locking bolt 3 and the thread through hole 120, and it is easy to understand that when the locking bolt 3 props against the groove bottom 21 of the preformed groove 2, friction force is generated to play a role in locking; wherein, if screw through hole 120 sets up the position between baffle and sharp boss, then this space is too narrow, leads to hardly going to operate the locking bolt, if screw through hole 120 sets up in the direction that the baffle was kept away from to sharp boss, because the locating part of inlayer more, the width of its sharp boss is big more, and the width of reserve groove is fixed, and is smaller moreover, consequently, set up screw through hole 120 in the direction that the baffle was kept away from to sharp boss, lead to the problem that the locking bolt can't stretch into the reserve groove very easily. Therefore, the threaded through hole is arranged on the linear boss so as to be a very reasonable choice.

Preferably, for the outermost limiting member, the linear boss 121 of the side plate 12 is provided with at least one limiting through hole 124; referring to fig. 10, when the outermost limiting member and the adjacent limiting member are overlapped, the adjacent limiting member has a threaded through hole 120 corresponding to the limiting through hole 124 in position, so that the limiting through hole 124 can be accessed to the locking bolt. The limiting through hole 124 may be, but need not be, threaded, and before the outermost limiting member is mounted, a locking bolt is used to string all the limiting members inside the outermost layer together and extend into the limiting through hole, so that all the limiting members can be locked together when stacked together, and the inner limiting member is prevented from sliding back and forth to hinder mounting when the outermost limiting member is mounted; of course, the storage and the transportation of the limiting device can be facilitated.

Preferably, for the threaded through holes on the same side plate, if the aperture of the threaded through hole is R, the distance between adjacent threaded screw holes ranges from 0.5R to 1.5R; or, for the threaded through holes on the same side plate, the distance between adjacent threaded through holes ranges from 1 cm to 3cm. Because in the transportation, the transport means always produces various rocks, only relies on frictional force, hardly reaches ideal locking effect, and the locating part that has moved up appears the condition that glides easily under various rocks. For this purpose, a locking system can be used: for two adjacent layers of limiting parts, if the limiting part on the inner layer extends upwards relative to the limiting part on the outer layer, and the limiting part on the inner layer at least has a threaded through hole, and is completely positioned above the side plate of the limiting part on the outer layer, at least one of the threaded through holes closest to the side plate is selected to be connected with the locking bolt 3; reference is made here to fig. 11.

According to the structural design, the distance between the adjacent threaded through holes is assumed to be R or 2cm; when the limiting part on the inner layer slides downwards relative to the limiting part on the outer layer, the sliding distance is necessarily less than 2R or R +2cm; therefore, the combination of the structural design and the locking mode enables all the limiting parts (excluding the outermost layer) to slide downwards, but the sliding distance is still small enough, so that the limitation of the liquid bag is basically not influenced negatively.

For example, assuming that all the limiting members of the limiting device are allocated to four height positions in total, the total sliding distance is necessarily less than 6R or 3r +6cm.

Preferably, referring to fig. 12, when the locking bolt 3 passes through the threaded through hole 120 and extends into the preformed groove 2 of the container, the side surface of the locking bolt 3 and the side wall 22 of the preformed groove 2 near the door of the container form a clearance fit. The pressure given by the container liquid bag can push the limiting device to move outwards or bend, so that by adopting the structural design, when each limiting part of the limiting device is pushed outwards by the pressure of the liquid bag, the locking bolt 3 can prop against the side wall 22 of the preformed groove 2, which is close to one side of the container door, so as to limit the limiting part to move outwards, and the problem that the container door cannot be closed due to the outward movement or bending of the limiting part is prevented. The above structural design is to improve the rigidity by using the locking bolt, and from this point of view, the more the locking bolt is used, the better.

The above embodiments are only preferred embodiments of the present invention, and the protection scope of the present invention is not limited thereby, and any insubstantial changes and substitutions made by those skilled in the art based on the present invention are within the protection scope of the present invention.
