Referring to fig. 1-4, an embodiment of the present invention provides an insert box beam, where the insert box beam and a rail assembly cooperate to form an insert box rail, and two side ends of the insert box rail can reciprocate along sliding grooves on two side walls of an insert box device under the action of external force. The box girder in this embodiment may specifically include a girder main body portion 11 and an insert 12. The crossbeam main body part 11 is connected with the guide rail assembly, and is provided with a containing part 10 along the length direction, the insert 12 is arranged in the containing part 10, the insert 12 is provided with a connecting part which is used for being connected with the extractor, and when the extractor is applied with external force, the guide rail assembly is driven to move; the guide rail assembly is suitable for bearing the single-plate assembly, so that the puller and the single-plate assembly are driven to move by the reaction force when the puller receives the action of external force. In particular, in the present embodiment, the beam main body 11 is a sheet metal member.

Here, it should be noted that the sheet metal part means: the product processed by the sheet metal process is called a sheet metal part. Sheet metal is an integrated cold working process for sheet metal (typically below 6 mm) and includes shearing, punching/cutting/compounding, folding, welding, riveting, splicing, forming, and the like. The remarkable characteristic is that the thickness of the same part is consistent.

In the present embodiment, the housing 10 refers to a single-sided structure or a multi-sided structure having an opening, and is not limited to an annular groove structure having an opening.

The material of the insert 12 is not limited in the embodiment of the present disclosure, and the insert 12 may be made of a corresponding material according to the weight of the veneer inserted on the rail assembly.

Because in the embodiment of the invention, the insert box cross beam is formed by splicing the cross beam main body part 11 and the insert 12, the cross beam main body part 11 is made of a sheet metal part, the sheet metal part has better tensile elongation, and the insert 12 is made of the insert 12 with corresponding materials according to the weight of a single plate inserted on the guide rail assembly, so that the insert 12 with better yield strength and hardness can be used as the insert 12 material in application. Therefore, the cross beam of the plug box in the embodiment of the invention has low cost and strong applicability.

In some embodiments of the present invention, the connecting portion of the insert 12 is defined within the space defined by the receiving portion 10. In this way, when the extractor is connected to the connecting portion of the insert 12 and forces are applied by the extractor, the periphery of the accommodating portion 10 is stressed, so that the problem that the beam main body 11 is deformed due to overlarge stress at a certain position of the accommodating portion 10 is avoided.

The connection of the insert 12 to the extractor includes, but is not limited to, a snap-lock connection. The manner in which the insert 12 is connected to the extractor is not limited in the present embodiment.

In some embodiments of the present invention, the insert 12 comprises: an insert 12 body, a working surface connected to a side of the insert 12 body opposite the rail assembly; a limiting structure is arranged on one side of the working surface, which is away from the body of the insert 12, so that the insert 12 is matched with the accommodating part 10; the connection is formed on the side of the working surface adjacent the body of the insert 12.

The insert 12 in this embodiment is preferably formed by casting, and may be specifically formed by die casting or in-mold molding. The material of insert 12 may be, but is not limited to, specifically zinc cast or cast steel material. Since the insert 12 is to be connected to the extractor, the die cast structure can ensure the yield strength and hardness of the insert 12.

The receiving portions 10 on the beam main body portion 11 are uniformly arranged in some embodiments of the present invention. It should be understood that even though a non-uniform arrangement of the receiving portion 10 is possible, a specific arrangement may be specifically designed according to the structure of the insert case.

In some embodiments of the present invention, the beam body 11 is formed by bending a steel plate using a sheet metal process, that is, the material of the beam body 11 is a steel plate, and the steel plate may be a galvanized steel plate, specifically, a cold-rolled steel plate, and is galvanized with zinc. The steel plate is used as the material of the beam main body 11 in the present embodiment because the material is relatively low in cost and the hardness can also satisfy the product demand.

The thickness of the plate material of the beam main body 11 in the embodiment of the present invention includes, but is not limited to, 1.5mm, and the thickness of the plate material specifically selected may depend on the weight required to be carried by the box beam.

The shape of the beam body 11 bent by the sheet metal in the present embodiment includes, but is not limited to, U-shape, Z-shape, L-shape, and the like. The beam main body 11 may have an integral structure or a split structure, and may have any structure obtained by bending by a sheet metal process. In order to clarify the connection between the beam body 11 and the insert 12, the following specific embodiments are given below.

In a first specific implementation manner, as shown in fig. 3, the beam main body 11 includes a first surface connected to the rail assembly, a second surface opposite to the first surface, and a third surface located between the first surface and the second surface; wherein openings are formed on the first surface and the third surface, and the openings on the first surface and the third surface are in one-to-one correspondence; the corresponding openings communicate and correspond to the receiving portions 10.

Of these, the first, second, and third surfaces of the beam body 11 are preferably formed as one piece. Namely, the same plate is bent by adopting a sheet metal process. The cross member body 11 has a U-shaped cross section perpendicular to the longitudinal direction thereof. The U-shape may be similar to the U-shape, that is, the first, second, and third surfaces may have bending patterns, and the bending patterns may be reinforcing ribs, so that the bending resistance of the beam main body 11 may be greatly enhanced. The size of the openings for the first and third faces is then dependent on the size of the insert 12. The insert 12 may be fixed to any one of the first, second, and third surfaces of the beam body 11.

Specifically, the insert 12 is exemplified as comprising an insert 12 body, and a working surface attached to the opposite side of the insert 12 body from the rail assembly. Wherein, a limit structure 123 is arranged on one side of the working surface of the insert 12, which is away from the body of the insert 12, so that the edge of the opening of the insert 12 and the third surface are matched; the connection is formed on the side of the working surface adjacent the body of the insert 12. It will be appreciated that since the working surface of the insert 12 can be limited to the edge of the opening of the third face, the working surface of the insert 12 protrudes from the receiving portion 10 to ensure that a force can be exerted on the insert 12 when the beam body 11 is pulled by the puller. Of course, it is preferable that the connecting portion of the insert 12 is formed at a side of the working surface near the body of the insert 12 and is defined in a space within the receiving portion 10, so that when a force is applied to the insert 12 by the puller, the force can be dispersed throughout the receiving portion 10 to avoid deformation due to an excessive force applied to a certain position of the receiving portion 10. The insert 12 body may be screwed to the second surface of the beam body 11. Of course, the body of the insert 12 and the beam body 11 may be fixed in a variety of ways, and this is not a mere example.

In a second specific embodiment, as shown in fig. 4, the beam main body 11 includes: a reinforcing beam 112 connected to the beam body 111 and disposed opposite to the beam body 111; the beam body 111 has an opening, and the position of the opening corresponds to the housing 10. The insert 12 may then be placed in the opening and secured to the reinforcement beam 112. The beam body 111 and the reinforcing beam 112 are both bent by adopting a sheet metal process.

Specifically, the insert 12 is exemplified as comprising an insert 12 body, and a working surface attached to the opposite side of the insert 12 body from the rail assembly. Wherein, a limit structure is arranged on one side of the working surface of the insert 12, which is away from the insert 12 body, so that the insert 12 is matched with the edge of the opening of the beam body 111; the connection is formed on the side of the working surface adjacent the body of the insert 12. It will be appreciated that since the working surface of the insert 12 can be limited to the edge of the opening of the beam body 111, the working surface of the insert 12 protrudes from the receiving portion 10 to ensure that a force can be applied to the insert 12 when the beam body 11 is pulled by the puller. Of course, it is preferable that the connecting portion of the insert 12 is formed at a side of the working surface near the body of the insert 12 and is defined in a space within the receiving portion 10, so that when a force is applied to the insert 12 by the puller, the force can be dispersed throughout the receiving portion 10 to avoid deformation due to an excessive force applied to a certain position of the receiving portion 10. The insert 12 body may be screwed to the reinforcing beam 112 of the beam body 11. Of course, the body of the insert 12 and the reinforcing beam 112 may be secured in a variety of ways, not specifically illustrated herein.

It should be noted that, although two specific implementations are given above, the present embodiment is not limited thereto, and any implementation where the insert box beam has a sheet metal process to form the beam main body 11 and splice the insert 12 is within the scope of the present embodiment.

As shown in fig. 5, the embodiment of the present invention further provides an incubator rail, which includes the incubator beam 1 of any one of the above embodiments, and of course, the incubator rail further includes a rail assembly 2 connected to the incubator beam.

Because the box rail in the embodiment of the invention comprises the box transverse beam 1, the box transverse beam 1 is formed by splicing the main beam body 11 and the insert 12, the main beam body 11 is made of sheet metal parts, the sheet metal parts have good tensile elongation, and the insert 12 can be made of the insert 12 with corresponding materials according to the weight of a single plate inserted on the rail assembly, so that the insert 12 can be made of materials with good yield strength and hardness in application. Therefore, the cross beam of the plug box in the embodiment of the invention has low cost and strong applicability.

In some embodiments of the present invention, the connection of the box girder 1 and the guide rail assembly 2 are in an integrated structure, that is, the box girder connection 1 and the guide rail assembly 2 are obtained through multiple bending by adopting a sheet metal process.

In some embodiments of the invention, the cartridge guide rail further comprises: a puller (not shown); the extractor is connected to the connecting portion of the insert 12 of the cross beam of the jack box in a manner including, but not limited to, a snap-lock connection.

The embodiment of the invention also provides the plug-in box equipment, which comprises the guide rail component in the embodiment, and the plug-in box equipment also comprises a box body and other components, which are not listed here.

It is to be understood that the above embodiments are merely illustrative of the application of the principles of the present invention, but not in limitation thereof. Various modifications and improvements may be made by those skilled in the art without departing from the spirit and substance of the invention, and are also considered to be within the scope of the invention.
