Detailed Description

In the related art, in order to further save the transport size of the shelf, a post-mounted bridge, that is, a bridge detachably installed between two cross members, has been developed. However, the rear-mounted bridge is usually fixed on the cross beam by means of screws and the like, and particularly, the bridge is difficult to install and has high risk coefficient when working aloft; or the bridge is connected with the cross beam through other connecting structures, so that the problems of complex connecting structure and high processing cost exist.

In order to solve the problems, the application provides the bridge, the cross beam, the goods shelf and the storage system, which can rapidly mount the bridge on the cross beam, is simple and convenient to operate, can limit the movement of the bridge relative to the cross beam, ensures that the goods shelf has good safety and reliability, and has a simple structure of a connecting structure between the bridge and the cross beam and is easy to process.

In order to make the above objects, features and advantages of the embodiments of the present application more comprehensible, the technical solutions of the embodiments of the present application will be described clearly and completely with reference to the accompanying drawings. It will be apparent that the described embodiments are only some, but not all, embodiments of the application. All other embodiments, which can be made by those skilled in the art based on the embodiments of the application without making any inventive effort, are intended to be within the scope of the application.

Example 1

Referring to fig. 1, an embodiment of the present application provides a shelf 100, including: two spaced-apart cross members 130 and a bridge 120 connected between the two cross members 130.

It will be appreciated that the pallet 100 further includes a support frame 110, two cross beams 130 are horizontally and spaced on the support frame 110, and the bridge 120 is connected between the two cross beams 130, for example, in fig. 1, the two cross beams 130 are horizontally spaced on the support frame 110, the bridge 120 is connected between the two cross beams 130, and the plurality of bridge 120 may be equally spaced in the extending direction of the cross beams 130, so that the two cross beams 130 and the plurality of bridge 120 connected between the two cross beams 130 together form a garage for placing goods. Wherein, along the direction vertical to the bottom surface, a plurality of storage positions can be arranged on the support frame 110.

It is understood that the support frame 110 is a support for the pallet 100, and is used to support the cross beam 130 and the like. In fig. 1, the supporting frame 110 includes four upright posts 111, the four upright posts 111 are disposed perpendicular to the bottom surface and are surrounded to form a rectangle, a supporting rod 112 is connected between two upright posts 111 at two ends of the beam 130, and an inclined included angle is formed between the supporting rod 112 and the upright posts 111, so as to improve the supporting strength of the supporting frame 110 through the supporting rod 112.

In some alternative embodiments, the end of the bridge 120 has a bearing portion 121 and a limiting portion 122, as shown in fig. 2-7, the bottom surface of the bearing portion 121 has a bearing surface 1211 facing the cross beam 130; the limiting portion 122 is connected to a side of the bearing portion 121, and a limiting hole 1221 is disposed on the limiting portion 122, where the limiting hole 1221 faces the side of the bearing portion 121. The cross beam 130 includes a cross beam body 131 and an adapter 132 disposed on the cross beam body 131, as shown in fig. 8 to 10, the top of the adapter 132 has an abutment surface 1321, the adapter 132 is provided with a receiving groove 1322, a notch of the receiving groove 1322 is disposed facing an end surface of the cross beam 120, and a limit clamping protrusion 1323 is disposed on a groove wall 1325 of the receiving groove 1322, so that when an end of the cross beam 120 is inserted into the receiving groove 1322, the limit clamping protrusion 1323 is clamped in the limit hole 1221, and the stress surface 1211 abuts against the abutment surface 1321 to limit movement of the cross beam 120 relative to the cross beam 130.

It is to be understood that the bearing portion 121 may be a bearing plate, and the limiting portion 122 may also be a limiting plate, and the bearing plate may be disposed horizontally, and the limiting plate is disposed laterally and vertically to the bearing plate.

In a specific implementation, the bridge 120 may move from the upper direction of the cross beam 130 to the direction close to the cross beam 130 (as shown in fig. 11), and the end of the bridge 120 may be directly inserted into the accommodating groove 1322 of the adaptor 132, that is, the limit part 122 at the end of the bridge 120 is inserted into the accommodating groove 1322, as shown in fig. 12 to 14, the limit clamping protrusion 1323 on the groove wall 1325 of the accommodating groove 1322 is clamped in the limit hole 1221 of the limit part 122, so that the installation between the bridge 120 and the cross beam 130 is realized, with simple structure and convenient operation; in addition, after the bridge 120 is connected with the cross beam 130, the movement of the bridge 120 relative to the cross beam 130 in the extending direction of the bridge 120 and the extending direction of the perpendicular bridge 120 can be limited, so that the risk that the bridge 120 falls off from the cross beam 130 is avoided, and the goods shelf 100 has good safety and reliability when carrying goods.

In addition, when the end of the bridge 120 is inserted into the accommodating groove 1322, as shown in fig. 12 to 14, the stress surface 1211 at the end of the bridge 120 abuts against the abutting surface 1321 on the adapter 132, so that when the load is placed on the bridge 120, the bridge 120 transfers the force borne by the bridge 120 to the abutting surface 1321 on the adapter 132 through the stress surface 1211, so as to avoid the risk that the bridge 120 falls off from the beam 130, ensure the transfer area of the force between the bridge 120 and the beam 130, and reduce the size that the upper surface of the bridge 120 protrudes out of the upper surface of the beam 130 after the bridge 120 is connected with the beam 130, thereby avoiding the problem that the load cannot enter and exit the shelf 100 due to the blocking of the end surface of the bridge 120 against the load or the end surface of the bridge 120 against the bottom of the load when the load enters and exits the shelf 100, and further improving the safety and reliability of the shelf 100.

In some alternative embodiments, as shown in fig. 2 to 7, there are two limiting portions 122 at the end of the bridge 120, and the two limiting portions 122 are symmetrically disposed on two sides of the bearing portion 121, and the stress surface 1211 is sandwiched between the two limiting portions 122, that is, the bearing portion 121 is sandwiched between the two limiting portions 122, and when the end of the bridge 120 is inserted into the accommodating groove 1322, the surface of the bearing portion 121 facing the cross beam 130 and abutting against the abutting surface 1321 is the stress surface 1211.

Optionally, at least one of the limiting portions 122 is provided with a limiting hole 1221, and the limiting hole 1221 faces a side of the bearing portion 121. In fig. 2 to 7, the two limiting portions 122 are provided with limiting holes 1221, and the limiting holes 1221 on the two limiting portions 122 are disposed opposite to each other.

The limiting hole 1221 may be any hole such as a square hole, an oval hole, or a trapezoid hole.

In fig. 2 to 7, the limiting hole 1221 is a square hole, and the limiting hole 1221 has a first hole edge 1221a and a second hole edge 1221b disposed opposite to each other, the first hole edge 1221a and the second hole edge 1221b being parallel to each other in the longitudinal direction of the bridge 120, such that when the limiting snap 1323 is snapped into the limiting hole 1221, the first hole edge 1221a and the second hole edge 1221b can limit the movement of the bridge 120 in the longitudinal direction of the bridge 120 (e.g., the first direction in fig. 6), and the hole edges adjacent to the first hole edge 1221a and the second hole edge 1221b, respectively, can limit the movement of the bridge 120 in the vertical ground direction (e.g., the third direction in fig. 6). In addition, when the end of the bridge 120 is inserted into the receiving groove 1322, the movement of the bridge 120 in the longitudinal direction (the second direction in fig. 6) of the cross member 130 may be restricted.

It will be appreciated that when the cargo is placed on the bridge 120, the first hole edge 1221a may limit the movement of the bridge 120 in the direction of the center of the bridge 120, so as to prevent the bridge 120 from moving too much in the direction of the bridge 120 and falling off from the cross beam 130, thereby improving the safety and reliability of the shelf 100.

During installation, an installer only needs to apply a vertical downward force to the end of the bridge 120, and the end of the bridge 120 slightly deforms the limit clamping protrusion 1323 in the process of being inserted into the accommodating groove 1322 of the adapter 132, and the limit clamping protrusion 1323 can be inserted into the limit hole 1221 by this deformation, so as to realize limit.

Optionally, the limiting clip 1323 includes a first limiting segment 1323a, a second limiting segment 1323b and a third limiting segment 1323c sequentially connected from top to bottom, where the second limiting segment 1323b is connected between the first limiting segment 1323a and the third limiting segment 1323c, and an inclined included angle is formed between the first limiting segment 1323a and the third limiting segment 1323c and the vertical direction, where the inclination degrees of the first limiting segment 1323a and the third limiting segment 1323c may be the same or different, in the embodiment of the present application, the inclination degrees of the first limiting segment 1323a and the third limiting segment 1323c are different, and specifically, the adaptive modification is performed according to the actual requirement, and the second limiting segment 1323b is parallel to the vertical direction, and because the first limiting segment 1323a of the limiting clip 1323 is in an inclined shape, the inclined shape may not need to apply a smaller vertical downward force to the end of the bridge 120, and the bridge 120 can be converted into a larger lateral pressing force to the limiting clip 1323, so that the bridge 120 is easy to install. When the spacing card 1323 is detached, the third spacing section 1323c of the spacing card 1323 is also in an inclined shape, so that the end of the bridge 120 is not required to be applied with a large vertical upward force, and the force can be converted into a large force for laterally extruding the spacing card 1323, thereby realizing the separation of the spacing hole 1221 and the spacing card 1323, and being easy to detach.

It should be appreciated that the limiting aperture 1221 may also be provided in other shapes. For example, the limiting aperture 1221 may be in the shape of a positive trapezoid or an inverted trapezoid. For another example, the stop hole 1221 may be circular or oval. The limiting aperture 1221 may be modified from these shapes, or may be formed from other polygonal or irregular straight and/or curved shapes. As the stopper hole 1221, a shape that can realize the stopper function in the first direction and the third direction as in fig. 6 may be used.

In order to further limit the falling of the bridge 120 from the cross beam 130, as shown in fig. 2 to 5, in the embodiment of the present application, a limit groove 1222 is further provided at one end of the limit part 122 facing away from the bearing part 121, a notch of the limit groove 1222 faces away from the bearing part 121, and when the bridge 120 is connected to the cross beam 130, the limit groove 1222 is inserted into a groove wall 1325 (as shown in fig. 12) of the accommodating groove 1322, so as to limit the bridge 120 along the length direction of the bridge 120, so that, while the limit clamp protrusion 1323 and the limit hole 1221 limit the bridge 120, the limit groove 1222 further limits the bridge 120 along the length direction of the bridge 120, thereby improving the reliability of limiting the bridge 120.

It should be noted that, the accommodating groove 1322 provided on the adapter 132 penetrates through the side wall of the adapter 132 facing the end of the bridge 120, so that the contour edge of the accommodating groove 1322 forms the groove wall 1325 of the accommodating groove 1322, when the bridge 120 is inserted into the accommodating groove 1322, the limiting groove 1222 is inserted into the groove wall 1325 at the bottom of the accommodating groove 1322 (as shown in fig. 12), so that the groove wall 1325 limits the movement of the bridge 120 along the length direction of the bridge 120, thereby achieving the purpose of further limiting the bridge 120, and improving the safety and reliability of the shelf 100.

Alternatively, the line between the limit slot 1222 and the limit hole 1221 is perpendicular to the length direction of the bridge 120, for example, when the shelf 100 is placed perpendicular to the ground, the bridge 120 is placed horizontally with respect to the ground, and the line between the limit slot 1222 and the limit hole 1221 is perpendicular to the ground, and the limit slot 1222 may be understood to be located below the limit hole 1221; in addition, along the length direction of the bridge 120, the slot width of the limiting slot 1222 is smaller than the width of the limiting hole 1221 (as shown in fig. 7), so that the limiting slot 1222 can limit the bridge 120 along the length direction of the bridge 120, the limiting hole 1221 can limit the bridge 120 further along the length direction of the bridge 120 on the basis of limiting the limiting slot 1222, and the risk that the bridge 120 falls off from the cross beam 130 is further reduced.

Optionally, the limiting slot 1222 has a first limiting surface 1222a and a second limiting surface 1222b opposite to each other, where the first limiting surface 1222a and the second limiting surface 1222b are parallel to each other in the length direction of the bridge 120, and an area of the first limiting surface 1222a may be greater than, equal to, or less than an area of the second limiting surface 1222 b.

Preferably, the first stop surface 1222a has an area greater than or equal to an area of the second stop surface 1222b, wherein the first stop surface 1222a faces away from the end of the bridge 120 and the second stop surface 1222b faces toward the end of the bridge 120.

It will be appreciated that when the load is placed on the bridge 120, the end of the bridge 120 moves toward the center of the bridge 120 under the gravity force of the load, and at this time, the first limiting surface 1222a of the limiting groove 1222 abuts against the side surface of the groove wall 1325 of the receiving groove 1322, and the groove wall 1325 of the receiving groove 1322 limits the movement of the end of the bridge 120 toward the center of the bridge 120, so as to prevent the end of the bridge 120 from falling off from the cross beam 130, and when the area of the first limiting surface 1222a is larger than the area of the second limiting surface 1222b (as shown in fig. 3 and 4), the limiting strength of the bridge 120 can be increased, thereby improving the safety and reliability of the shelf 100.

It should be noted that, the slot width of the limit slot 1222 is matched with the thickness dimension of the slot wall 1325 of the receiving slot 1322, so that the limit slot 1222 can be inserted on the slot wall 1325 of the receiving slot 1322.

Optionally, the size of the limit slot 1222 along the length direction of the vertical bridge 120 may be determined by the user according to the requirement of the limit strength, for example, in fig. 7, the size of the limit slot 1222 along the length direction of the vertical bridge 120 may be increased to achieve the purpose of increasing the area of the first limit surface 1222a, thereby achieving the limit strength of increasing the limit strength of the limit bridge 120 moving along the length direction of the bridge 120.

Of course, the limiting slot 1222 may be omitted, as shown in fig. 6, so as to form an avoiding opening at the bottom of the limiting portion 122, so that the limiting portion 122 is inserted into the receiving slot 1322, and is blocked in the limiting hole 1221 by the limiting blocking protrusion 1323 to limit the movement of the bridge 120 relative to the cross beam 130.

Example two

Referring to fig. 2 to 5, an embodiment of the present application provides a bridge 120, which is applied to a shelf, for example, the shelf may be the shelf 100 provided in the foregoing embodiment, where the bridge 120 is connected between two cross beams of the shelf, an end portion of the bridge 120 has a bearing portion 121 and a limiting portion 122, as shown in fig. 2 to 5, a bottom surface of the bearing portion 121 has a stress surface 1211 facing the cross beam, and the stress surface 1211 is configured to abut against a top portion of the cross beam; the limiting portion 122 is connected to a side of the bearing portion 121, a limiting hole 1221 is disposed on the limiting portion 122, the limiting hole 1221 faces the side of the bearing portion 121, and the limiting hole 1221 is configured to be clamped with a limiting structure on the cross beam, so as to limit the movement of the bridge 120 relative to the cross beam.

It is to be understood that the bearing portion 121 may be a bearing plate, and the limiting portion 122 may also be a limiting plate, and the bearing plate may be disposed horizontally, and the limiting plate is disposed laterally and vertically to the bearing plate. The limiting structure on the cross beam can be a limiting clamping protrusion.

In this way, when the end of the bridge 120 is connected with the cross beam, the limit clamp on the groove wall of the accommodating groove is clamped in the limit hole 1221, so that the installation and limit between the bridge 120 and the cross beam can be realized, the structure is simple, the operation is convenient, the safety and reliability are high, in addition, after the bridge 120 is connected with the cross beam, the movement of the bridge 120 relative to the cross beam can be limited, and therefore, the movement of the bridge 120 relative to the cross beam in the extending direction of the bridge 120 and the extending direction of the vertical bridge 120 can be limited, the risk that the bridge 120 falls off from the cross beam can be avoided, and the goods shelf has good safety and reliability when carrying goods.

In addition, when the end of the bridge 120 is connected with the cross beam, the stress surface 1211 at the end of the bridge 120 is abutted against the top of the cross beam, so that when the bridge 120 is used for placing goods, the bridge 120 transmits the force borne by the bridge 120 to the cross beam through the stress surface 1211, so that the risk that the bridge 120 falls off from the cross beam is avoided, meanwhile, the force transmission area between the bridge 120 and the cross beam is ensured, the size that the upper surface of the bridge 120 protrudes out of the upper surface of the cross beam after the bridge 120 is connected with the cross beam is also reduced, and the problem that goods cannot enter and exit the shelf due to blocking of the end surface of the bridge 120 by the goods when the goods enter and exit the shelf is avoided, or the problem that the bottom of the goods is scratched by the end surface of the bridge 120 is avoided, and the safety and reliability of the shelf are further improved.

In some alternative embodiments, as shown in fig. 2 to 5, there are two limiting portions 122 at the end of the bridge 120, and the two limiting portions 122 are symmetrically disposed on two sides of the bearing portion 121, and the stress surface 1211 is sandwiched between the two limiting portions 122, that is, the bearing portion 121 is sandwiched between the two limiting portions 122.

Optionally, at least one of the limiting portions 122 is provided with a limiting hole 1221, and the limiting hole 1221 faces a side of the bearing portion 121. In fig. 2 to 5, the two limiting portions 122 are provided with limiting holes 1221, and the limiting holes 1221 on the two limiting portions 122 are disposed opposite to each other.

In fig. 2 to 5, the limiting hole 1221 is a square hole, and the limiting hole 1221 has a first hole edge 1221a and a second hole edge 1221b that are disposed opposite to each other, where the first hole edge 1221a and the second hole edge 1221b are parallel to each other in the length direction of the bridge 120, so that when the limiting clip is engaged in the limiting hole 1221, the bridge 120 can be limited in the length direction along the vertical bridge 120.

For example, when the bridge 120 is horizontally placed, the movement of the bridge 120 in a vertical direction perpendicular to the ground may be restricted, and the first hole edge 1221a and the second hole edge 1221b may restrict the movement of the bridge 120 in a longitudinal direction of the bridge 120, for example, when goods are placed on the bridge 120, the first hole edge 1221a may restrict the movement of the bridge 120 in a center direction of the bridge 120, so as to prevent the bridge 120 from moving too much in the direction of the bridge 120 to fall off from the cross beam, thereby improving the safety reliability of the shelf.

In order to further limit the falling off of the bridge 120 from the cross beam, as shown in fig. 2 to 5, in the embodiment of the present application, a limiting slot 1222 is further disposed at an end of the limiting portion 122 facing away from the bearing portion 121, and a notch of the limiting slot 1222 facing away from the bearing portion 121, so that when the bridge 120 is connected to the cross beam, the limiting slot 1222 is inserted into a receiving structure fixed relative to the cross beam, and limits the bridge 120 along the length direction of the bridge 120.

Optionally, the accommodating structure fixed relative to the cross beam may be a groove wall of an accommodating groove disposed on the cross beam, so that when the bridge 120 is connected to the cross beam, the limiting groove 1222 is inserted into the groove wall of the accommodating groove to limit the bridge 120 along the length direction of the bridge 120, and thus, when the limiting clamp is raised and the limiting hole 1221 limits the bridge 120, the limiting groove 1222 further limits the bridge 120 along the length direction of the bridge 120, so that the reliability of limiting the bridge 120 can be improved.

It should be noted that, the cross beam may be provided with a receiving groove, and the contour edge of the receiving groove forms a groove wall of the receiving groove, when the bridge 120 is inserted into the receiving groove, the limiting groove 1222 is inserted into the groove wall at the bottom of the receiving groove, so that the groove wall 1325 limits the movement of the bridge 120 along the length direction of the bridge 120, thereby achieving the purpose of further limiting the bridge 120, and improving the safety and reliability of the shelf 100.

Optionally, the limiting slot 1222 has a first limiting surface 1222a and a second limiting surface 1222b disposed opposite to each other, the first limiting surface 1222a and the second limiting surface 1222b are parallel to each other in the length direction of the bridge 120, and the area of the first limiting surface 1222a is greater than or equal to the area of the second limiting surface 1222b, where the first limiting surface 1222a faces away from the end of the bridge 120, and the second limiting surface 1222b faces toward the end of the bridge 120.

It will be appreciated that when the load is placed on the bridge 120, the end of the bridge 120 moves toward the center of the bridge 120 under the gravity force of the load, and at this time, the first limiting surface 1222a of the limiting groove 1222 abuts against the side surface of the groove wall of the receiving groove, and the groove wall of the receiving groove limits the movement of the end of the bridge 120 toward the center of the bridge 120, so as to prevent the end of the bridge 120 from falling off the cross beam 130, and when the area of the first limiting surface 1222a is larger than the area of the second limiting surface 1222b (as shown in fig. 3 and 4), the limiting strength of the bridge 120 can be increased, thereby improving the safety and reliability of the shelf.

It should be noted that, the slot width of the limit slot 1222 is matched with the thickness dimension of the slot wall of the accommodating slot, so that the limit slot 1222 can be inserted into the slot wall of the accommodating slot.

Of course, the limiting slot 1222 may be omitted, as shown in fig. 6, so as to form an avoiding opening at the bottom of the limiting portion 122, so that the limiting portion 122 is inserted into the accommodating slot, and is engaged in the limiting hole 1221 by the limiting clip to limit the movement of the bridge 120 relative to the cross beam.
