The remarkable characteristic is that the thickness of the same part is consistent.
In the present embodiment, the receiving portion 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 material of the insert 12 may be the insert 12 made of a corresponding material according to the weight of the veneer inserted on the guide rail assembly.
In the embodiment of the invention, the cross beam of the insert box 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 sheet metal parts, the sheet metal parts are made of a material with better tensile strength, and the insert 12 made of a corresponding material can be selected according to the weight of a veneer inserted on the guide rail assembly, so that the insert 12 made of a material with better yield strength and hardness can be selected as the material of the insert 12 in application. Therefore, the inserting box beam 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. Thus, when the extractor is connected to the connecting portion of the insert 12 and the force is applied by the extractor, the periphery of the accommodating portion 10 is stressed, so as to avoid the problem that the main beam body 11 is deformed due to the excessive stress applied to a certain position of the accommodating portion 10.
The connecting portion of the insert 12 is connected to the extractor in a manner including, but not limited to, snap-fit connection. The manner of connecting the insert 12 to the extractor is not limited in the embodiments of the present invention.
In some embodiments of the present invention, the insert 12 comprises: the insert 12 body is connected with a working surface on the side surface of the insert 12 body opposite to the guide rail assembly; a limiting structure is arranged on one side of the working surface, which is far away from the insert 12 body, so that the insert 12 is matched with the accommodating part 10; the connecting portion is formed on the side of the working surface adjacent to the body of the insert 12.
In the present embodiment, the insert 12 preferably adopts a casting structure, and may be specifically formed by die casting or in-mold forming. The material of the insert 12 may be, but is not limited to, cast zinc or cast steel. Because the insert 12 is connected with the extractor, the die-casting 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 portions 10 is possible, the specific arrangement may be specifically designed according to the structure of the outlet box.
In some embodiments of the present invention, the beam main body 11 is formed by bending a steel plate by a sheet metal, that is, the material of the beam main body 11 is a steel plate, and the steel plate may be a galvanized steel plate, specifically, a cold-rolled steel plate, and is electroplated with color zinc. The steel plate used in the present embodiment as the material of the beam main body portion 11 is because the material is relatively low in cost and the hardness can also meet the product requirements.
The thickness of the plate of the cross beam main body portion 11 in the embodiment of the present invention includes, but is not limited to, 1.5mm, and the thickness of the plate to be selected may be determined according to the weight to be carried by the cross beam of the box.
In the present embodiment, the shapes of the beam main body 11 bent by the sheet metal include, but are not limited to, U-shape, Z-shape, L-shape, and the like. The beam main body 11 may be an integral structure or a split structure, and may be any structure obtained by bending through a sheet metal process. In order to clarify the connection relationship between the beam main body 11 and the insert 12, the following embodiments are given below.
In a first specific implementation manner, as shown in fig. 3, the cross beam main body portion 11 includes a first surface connected to the rail assembly, a second surface disposed opposite to the first surface, and a third surface located between the first surface and the second surface; the first surface and the third surface are provided with openings, and the openings on the first surface and the third surface correspond to each other one by one; the corresponding openings communicate with each other and correspond to the receiving portion 10.
The first surface, the second surface, and the third surface of the cross beam body 11 are preferably formed in an integral structure. That is, the same plate is bent by a sheet metal process. The cross-beam main body portion 11 has a U-shaped cross section perpendicular to the longitudinal direction thereof. The U-shape may be similar to a U-shape, that is, the first surface, the second surface, and the third surface may be surfaces having a bending pattern, and the bending pattern is a reinforcing rib, which may greatly enhance the bending resistance of the beam main body portion 11. The size of the openings for the first and third faces is dependent on the size of the insert 12. The insert 12 may be fixed to any one of the first surface, the second surface, and the third surface of the beam main body 11.
Specifically, the insert 12 includes an insert 12 body, and a working surface connected to a side surface of the insert 12 body opposite to the guide rail assembly. Wherein, a limit structure 123 is arranged on one side of the working surface of the insert 12, which is far away from the body of the insert 12, so that the insert 12 is matched with the edge of the opening of the third surface; the connecting portion is formed on the side of the working surface adjacent to 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 is protruded from the receiving portion 10 to ensure that a force can be applied to the insert 12 when the beam main body portion 11 is pulled by the puller. Of course, it is preferable that the connecting portion of the insert 12 is formed on a side of the working surface close to the body of the insert 12 and is limited to the space in the housing 10, so that when a force is applied to the insert 12 by the extractor, the force can be dispersed throughout the housing 10 to avoid deformation of the housing 10 due to an excessive force applied to a certain position. The insert 12 body may be fixed to the second surface of the beam main body 11 by screws. Of course, the fixing manner of the insert 12 body and the beam main body 11 can be various, and is not listed here.
In a second specific implementation, as shown in fig. 4, the beam main body portion 11 includes: a reinforcement beam 112 connected to the rail assembly and disposed opposite to the beam body 111; the beam body 111 has an opening at a position corresponding to the accommodating portion 10. The insert 12 may then be placed in the opening and secured to the reinforcement beam 112. The beam body 111 and the reinforcement beam 112 are both formed by bending through sheet metal process.
Specifically, the insert 12 includes an insert 12 body, and a working surface connected to a side surface of the insert 12 body opposite to the guide rail assembly. Wherein, a limit structure is arranged on one side of the working surface of the insert 12, which is far away from the body of the insert 12, so that the insert 12 is matched with the edge of the opening of the beam body 111; the connecting portion is formed on the side of the working surface adjacent to the body of the insert 12. It can be understood 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 is protruded from the receiving portion 10 to ensure that a force can be applied to the insert 12 when the beam main body portion 11 is pulled by the puller. Of course, it is preferable that the connecting portion of the insert 12 is formed on a side of the working surface close to the body of the insert 12 and is limited to the space in the housing 10, so that when a force is applied to the insert 12 by the extractor, the force can be dispersed throughout the housing 10 to avoid deformation of the housing 10 due to an excessive force applied to a certain position. The insert 12 body may be fixed to the reinforcement beam 112 of the beam main body 11 by screws. Of course, the manner of fixing the insert 12 to the reinforcement beam 112 may be various, and is not listed here.
It should be noted that, the above two specific implementation manners are only given, but the present embodiment is not limited thereto, and it is within the protection scope of the embodiment of the present invention as long as the box girder has a sheet metal process to form the girder main body 11 and the insert 12 to be spliced together.
As shown in fig. 5, an embodiment of the present invention further provides a box rail, which includes any one of the box beams 1 in the above embodiments, and of course, the box rail further includes a rail assembly 2 connected to the box beam.
Because the insert box guide rail in the embodiment of the invention comprises the insert box cross beam 1, the insert box cross beam 1 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 sheet metal parts, the sheet metal parts are made of materials with better tensile strength, and the insert 12 made of corresponding materials can be selected according to the weight of a veneer inserted on the guide rail assembly, so that the insert 12 made of materials with better yield strength and hardness can be selected as the materials of the insert 12 in application. Therefore, the inserting box beam in the embodiment of the invention has low cost and strong applicability.
In some embodiments of the present invention, the box girder 1 and the rail assembly 2 are an integral structure, that is, the box girder 1 and the rail assembly 2 are obtained by bending for many times through a sheet metal process.
In some embodiments of the invention, the subrack rail further comprises: an extractor (not shown); the extractor is connected to the connection portion of the insert 12 of the cross-beam of the jack, and the connection manner of the extractor and the insert includes but is not limited to a locking connection.
