Description

Technical Field

[0001] The utility model relates to the technical field of anti - skid chain packaging, and particularly relates to a storage box for truck anti - skid chains. Background Art

[0002] At present, when heavy vehicles such as trucks are driving on snowy days and muddy roads, anti - skid chains must be always prepared to ensure driving safety.

[0003] Most of these iron anti - skid chains weigh between 20 - 60KG, making it impossible for conventional plastic boxes to withstand the destructive forces caused by inertia of these anti - skid chains during stacking and transportation. Therefore, these heavy - duty anti - skid chains are usually packaged in canvas or woven bags.

[0004] Generally, there is no handle position on the canvas bag, which makes it difficult to carry the anti - skid chains. Moreover, the chains of the anti - skid chains are easily entangled and knotted in the canvas bag, making it very difficult to sort out during actual installation and use. Also, since the iron chains are extremely prone to rust and corrosion after being worn, they need to be dried and oiled for storage. Therefore, after the anti - skid chains are used, the storage bags are basically discarded and cannot be reused. Summary of the Invention

For those of ordinary skill in the art, the specific meanings of the above terms in the present utility model can be understood according to specific circumstances.

[0040] Figure 1 is the truck anti-skid chain storage box provided by the embodiment of the present application. As Figure 1 shown, the truck anti-skid chain storage box includes: a box body 10, a cover body 20, a column body 30, a handle 40, a first locking structure 50, and a second locking structure 60.

[0041] Among them, the box body 10 can be generally in the shape of a cuboid. It is open at the top, and an accommodation space for accommodating the iron chain is formed inside. The cover body 20 is rotatably connected to the box body 10 and can rotate relative to the box body to close or open the top opening of the box body for the iron chain to be put in or taken out.

[0042] The column body 30 is located inside the box body 10. It extends from the central position of the bottom of the box body along the height direction to an appropriate height. Specifically, the column body 30 can be a hollow structure composed of multiple plate-like structures supporting each other, providing a sufficient support area.

[0043] The handle 40 is arranged on the outer surface of the cover body 10. A cover body through hole 21 is arranged at the central position of the cover body 20, and the handle 40 can rotate around the central axis of the cover body through hole 21, thereby driving a relative position change between the locking structures.

[0044] The first locking structure 50 is formed at the end of the column body 30 far from the bottom of the box body, while the second locking structure 60 is located on the inner surface of the cover body. The second locking structure 60 is also connected to the handle 40 through the cover body through hole 21, so that it can rotate following the handle 40.

[0045] During actual use, as Figures 4 to 7 shown, when the second locking structure 60 rotates following the handle 40 to the locking position, it can engage with the first locking structure 50, thereby restricting the cover body 20 from flipping upward relative to the box body 10, so that the cover body 20 remains locked to close the top opening of the box body.

[0046] When the second locking structure 60 rotates following the handle 40 to the unlocking position, it will disengage from the first locking structure 50 and no longer constitute a restriction. At this time, the cover body 20 can flip upward relative to the box body 10 to open the top opening of the box body for the anti-slip chain 1 to be put in or taken out.

[0047] Preferably, as Figure 1 shown, in order to put in multiple anti-slip chains at the same time, the truck anti-slip chain storage box can also include: a partition 70. Among them, a partition through hole 71 allowing the column body 30 to pass through is opened at the center of the partition 70.

[0048] During actual use, an anti-slip chain with a certain length is rotatably put into the inside of the box body 10 in a way that surrounds the column body 30 located at the center. After putting in one anti-slip chain, the partition through hole 71 is correspondingly aligned with the column body 30 and then put into the inside of the box body 10 to form a relatively independent accommodation space. Subsequently, another anti-slip chain is put in to achieve the spaced accommodation of multiple truck anti-slip chains. The two anti-slip chains can be separated by the partition 70 and will not be entangled with each other.

[0049] The anti-skid chain storage box provided by the embodiment of the utility model, through the design of the column, the first anti-slip structure and the second anti-slip structure, enables the storage box to interact in all directions at the locking position after being locked and lifted, and the positions prone to deformation under force support each other, ensuring sufficient bearing capacity.

[0050] As Figure 8 shown, the stress point of the column is located at the center of the box, which can directly transfer the acting force to the bottom of the box, ensuring that the heavy object can be lifted without deformation. Moreover, when the stacking height of the anti-skid chains during transportation is high, a strong support point is provided by the column at the center position, avoiding the problem that conventional boxes are prone to deformation and damage due to the hollow in the middle.

[0051] In addition, during storage, the anti-skid chains can be placed annularly around the column at the center position, and multiple anti-skid chains can also be spaced apart by placing partitions, ensuring that they will not be entangled when taken out during use and also facilitating storage after use.

[0052] In some embodiments, as Figure 3 shown, the handle 40 includes: a handle base 41 and a handle part 42.

[0053] Among them, the handle base 41 passes through the through-hole of the cover body and is rigidly connected to the center of the second anti-slip structure 60, forming an integral structural component that can rotate around the central axis of the through-hole of the cover body. Specifically, the handle base 41 can be a component integrally formed with the second anti-slip structure 60 and extends upward from the upper surface of the second anti-slip structure 60.

[0054] The handle part 42 forms a part for the user to hold. It is connected to the handle base 41 through a rotating shaft 43, so that the handle part 42 can rotate around an axis parallel to the outer surface of the cover body, so that the handle part 42 can be flipped back to a position close to the outer surface of the cover body 20 when not in use.

[0055] Specifically, the handle part 42 and the handle base 41 can be connected to each other by means of a metal rivet 43, so that the handle part 42 can rotate around the axis of the metal rivet 43.

[0056] More specifically, the handle 40 may further include a fixing fastener 44. The fixing fastener 44 can be fixedly connected to the handle base 42 by means of snap connection, so that the rotatable handle base 42 is stably arranged on the inner surface of the cover body and rotates around the central axis.

[0057] Preferably, in order to facilitate the stacking, transportation and placement of the box body, a receiving recess 22 adapted to the handle part is further provided on the outer surface of the cover body 20.

[0058] Thus, when the handle portion 42 rotates relative to the handle base 41 to the storage position, it can be stored inside the storage recess 22 without protruding from the surface of the lid body 20, keeping the surface of the lid body 20 flush.

[0059] During actual use, when it is necessary to unlock or lock the lid body 20, the handle portion 42 can be lifted from the storage recess by a certain angle, and then by rotating the handle portion 42, the handle base 41 is driven to rotate around the central axis of the lid through-hole, so that the second locking structure moves between the unlocking position and the locking position.

[0060] When the user needs to carry the truck anti-skid chain storage box, the handle portion 42 can be further rotated to a position substantially perpendicular to the outer surface of the lid body. By holding the handle portion 42, the truck anti-skid chain storage box can be lifted and carried to a suitable position.

[0061] In some embodiments, the storage recess 22 can be specifically provided with an additional recessed gripping portion 202 so that the user's fingers can reach in and lift the handle portion 42.

[0062] Preferably, a plurality of indication marks 23 can be provided on the outer surface of the lid body 20. These indication marks 23 have a linkage relationship with the position of the second locking structure and are respectively used to indicate whether the second locking structure 60 is currently in the locking position or the unlocking position, so as to prompt the user and avoid accidents caused by mistakenly lifting the unlocked lid body.

[0063] Preferably, as Figure 12 shown, a suitable angle limiting device 90 can also be provided between the handle base 42 and the hole wall of the lid through-hole 21. Through this angle limiting device, the second locking structure is restricted to rotate between the unlocking position and the locking position.

[0064] Since the second locking structure 60 rotates circumferentially relative to the first locking structure 50, it is easy for the second locking structure 60 to rotate too many angles and leave the locking position again to the unlocking position, which requires the user to appropriately adjust the angle. The design of the above-mentioned angle limiting device 90 can bring convenience to the user. When the user rotates and switches the state of the second locking structure 60, the user only needs to directly rotate to the limit position.

[0065] In some embodiments, as Figure 2 shown, the first locking structure 50 can include: a first structural body 51a and two first locking portions 52a.

[0066] Wherein, the two first locking portions 52a respectively extend outward from two opposite sides of the first structure body 51a. They can cooperate with the side edges of the first structure body 51a to form a square groove 53a with openings at both ends.

[0067] Correspondingly, the second locking structure 60 includes: a second structure body 61a and two second locking portions 62a.

[0068] Wherein, the upper surface of the second structure body 61a is connected to the handle 40. The two second locking portions 62a respectively extend downward from the lower surface of the second structure body 61a by a preset distance, so as to form a receiving space for receiving the first locking portion 52a. In addition, a square protrusion 63a is formed at the end of the second locking portion 62a, which is adapted to the square groove 53a.

[0069] Thus, when the first locking structure 50 and the second locking structure 60 are combined with each other, the first locking portion 51a and the second locking portion 61a can be engaged with each other to provide a strong enough supporting force to ensure that the cover body 20 will not turn over.

[0070] Preferably, the interval between the two second locking portions 61a is adapted to the radial dimension of the first structure body 51a, so that the second locking structure 60 can rotate with the handle without interference with the first locking structure 50. Specifically, an arc-shaped interval can be formed between the two second locking portions 62a, which is adapted to the columnar first structure body 51a.

[0071] In some other embodiments, the present invention further provides another implementation manner of the first locking structure and the second locking structure, which can also provide a strong supporting force. Figures 9 to 1 Figure 3 shows another implementation manner of the first locking structure and the second locking structure.

[0072] As Figures 9 to 13A shown, the first locking structure 50 includes: a pair of first locking members 51b which are oppositely arranged with a preset interval therebetween.

[0073] Wherein, the first locking member 51b has a supporting portion 501b, a locking portion 502b and a limiting portion 503b.

[0074] The supporting portion 501b extends in the height direction, and the locking portion 502b extends horizontally along the cover body from the end of the supporting portion 501b. The two form a structure similar to an L shape. The limiting portion 503b is located at the end of the locking portion 502b and protrudes towards the columnar body, so as to form a limiting space in combination with the locking portion 502b and the limiting portion 503b.

[0075] Correspondingly, the second latching structure 60 includes: a columnar base 61b and a pair of second latching members 62b.

[0076] Among them, the pair of second latching members 62b are located in the same linear direction and extend respectively from the surface of the columnar base 61b to both sides. A protrusion 63b adapted to the limiting space is further formed at the end of the second latching member 62b.

[0077] Thus, when the first latching structure 50 and the second latching structure 60 are combined with each other, the first latching member 51b and the second latching member 61b can be engaged with each other to provide a sufficiently strong supporting force to ensure that the cover body 20 will not turn over.

[0078] Preferably, the latching portion 502b can be arc-shaped, and a suitable distance is spaced between the pair of latching portions 502b to form a circular space adapted to the radial dimension of the columnar base 61b, so that the second latching structure 60 can rotate following the handle without interference with the first latching structure 50.

[0079] Specifically, the second latching structure 60 may further include a pair of side walls 64b.

[0080] Among them, the side walls 64b are fixedly arranged on the inner surface of the cover body 20. The pair of side walls 64b are symmetrically arranged along the columnar base 61b and have a preset distance from the columnar base 61b, so that when the cover body 20 is turned over and closed, the side walls 64b are in contact with the outer side surface of the supporting portion 501b of the first latching structure.

[0081] Figure 13A and Figure 13B shows the force-bearing situation when the second latching structure rotates to the locking position and the lid of the truck anti-skid chain storage box outputs the locked state.

[0082] As Figure 13B shown, the size and structure settings of the mutual cooperation between the above-mentioned first latching structure 50 and the second latching structure 60 make the structural components at positions P1, P2, and P3 lock with each other when the second latching structure 60 rotates to the locking position, so that the whole box mainly bears the tensile force in the vertical direction at this time.

[0083] After the user lifts the box by the handle, the tightly engaged first latching member 51b and second latching member 62b can support each other, and the side walls 64b of the second latching structure can also support the supporting portion 501b of the first latching structure, which is in line with the material mechanics characteristics of the plastic material and enables the box to withstand a strong acting force.

[0084] During actual use, the above-mentioned mutually engaging first locking member 51b, second locking member 62b, and the column 30 form a continuous support structure within the entire box body, which abuts between the bottom of the body 20 and the box body 10.

[0085] Figure 15 Fig. shows the stacking state of multiple truck anti-skid chain storage boxes provided by the embodiments of the present application. As Figure 15 shown, when multiple truck anti-skid chain storage boxes are stacked in the height direction, the support structures inside each truck anti-skid chain storage box are located at substantially the same position. Thus, a stable support structure is formed inside the stacked box body, and the gravity borne is transmitted to the stacking ground one by one through the support structure. At this time, parts such as the side walls of the box body no longer need to bear a large pressure, ensuring that the box body will not be deformed when stacked.

[0086] Preferably, the bottom of the box body 10 and the upper surface of the cover body 20 can be provided with appropriate structural settings so that two adjacent stacked truck anti-skid chain storage boxes can be stacked conveniently and correctly, maintaining the position consistency of the internal support structure. For example, the bottom 10 of the box body 10 can be provided with a card slot 70 adapted to the upper surface of the cover body 20, and relative sliding between the two stacked boxes can be avoided through this card slot 70.

[0087] The above content is a further detailed description of the present invention in combination with specific / preferred embodiments, and it cannot be determined that the specific implementation of the present invention is limited to these descriptions. For those of ordinary skill in the art, without departing from the concept of the present invention, several deformations and improvements can still be made, and these all belong to the protection scope of the present invention.
