[0001] The invention relates to the field of frame structures, and in particular to a connection structure for a frame body, a frame body and an installation method. Background Art

[0002] The urn storage rack is the most widely used in the modern funeral industry. The urn storage device has various shapes, specifications and structures. However, the existing urn storage racks are basically sheet metal or plastic-formed frames, with a single structure and poor commonality. Different sizes and specifications of the grid need to be opened with different molds, resulting in a lot of unnecessary waste, which does not conform to the environmental protection and conservation concept strongly advocated by the country. In order to solve the above problems, patent document CN 205153679 U discloses an assembled storage device, which adopts a frame structure with various structural changes. The components can be universal, achieving the purpose of environmental protection and conservation. However, its longitudinal and / or vertical bars are directly installed on the joint, relying on the joint to bear the gravity transmitted by it. In this way, the joint itself must have a reliable supporting capacity, but the general structure of the connector is relatively complex and is not suitable for being made of solid materials. In this way, the connector becomes a bottleneck that limits the storage capacity and firmness of the assembled storage device. If the storage capacity and firmness of the storage device need to be improved, it is necessary to improve the firmness of the connector, which has become a common practice to improve the above patent documents.

DETAILED DESCRIPTION

[0034] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0035] The purpose of the present invention is to provide a connection structure for a frame-type frame, a frame-type frame and an installation method to solve the problems existing in the prior art, so that beams or columns in all directions can bear the load, the requirements for joint strength are reduced, and the load-bearing performance and stability of the storage rack structure are significantly improved.

[0036] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the present invention is further described in detail below with reference to the accompanying drawings and specific embodiments.

[0037] like Figure 1-2As shown, the present invention provides a connection structure for a frame-type frame, including a joint 1 and an annular support 2, the joint 1 includes a joint body 1.1, and the joint body 1.1 is provided with at least three protrusions 1.2. It should be noted that in this embodiment, the joint body 1.1 is a rectangular parallelepiped structure, but in fact, the joint body 1.1 can be any shape, such as spherical, prism-shaped, polyhedral, as long as it can ensure that adjacent protrusions 1.2 are perpendicular to each other, and the structure matched with the protrusion 1.2 is an annular support 2, and the number of the annular support 2 and the protrusion 1.2 corresponds one to one, and the protrusion 1.2 is completely inserted into the inner cavity of the annular support 2, and the protrusion 1.2 is connected to the annular support 2. It is clear that after the protrusion 1.2 is inserted into the inner cavity of the annular support 2, the protrusion 1.2 and the annular support 2 can also be connected by means of screw connection, riveting, welding, etc., so that the protrusion 1.2 can be firmly connected to the annular support 2, and after the above-mentioned installation is completed, the outer walls of adjacent annular supports 2 fit together, the horizontal annular supports 2 fit together with the outer walls of the vertical annular supports 2, and the outer walls of the horizontal annular supports 2 and the horizontal annular supports 2 also fit together. In other words, the annular supports 2 can transmit force to each other, and the joint 1 only plays a connecting role, and it does not bear the effect of gravity, thereby significantly reducing the requirements for the joint strength.

[0038] In this embodiment, the connection method between the protrusion 1.2 and the annular support 2 is simplified to an interference fit method. The protrusion 1.2 is directly inserted into the inner cavity of the annular support 2, and no other fixing method is required. This connection method can improve simplicity while ensuring the stability of the installation structure.

[0039] like Figure 1 and Figure 3 As shown, the inner surface of the annular support 2 is provided with a first ridge 3 protruding inward. After the protrusion 1.2 is installed in the inner cavity of the annular support 2, the side of the first ridge 3 can contact the protrusion 1.2. At this time, the first ridge 3 can limit the displacement of the protrusion 1.2, and the two form an interference fit installation form with each other. On the other hand, the setting of the first ridge 3 can reduce the wall thickness of the annular support 2, thereby significantly reducing the material consumption of the annular support 2. At the same time, the first ridge 3 of the vertically arranged annular support 2 can also form an effective support for the laterally arranged annular support 2 above it, thereby improving the supporting capacity of the annular support 2. In fact, the first ridge 3 is also equivalent to a reinforcing rib provided on the annular support 2, which can improve the stability of the overall structure of the annular support 2.

[0040] like Figure 1-2 As shown, the joint body 1.1 is provided with a wing plate 1.3, and the side of the wing plate 1.3 is parallel to the side of the annular support 2, please refer to Figure 2 and Figure 3The wing plate 1.3 is arranged on the side facing the personnel operation. At this time, the wing plate 1.3 can cover the gap between the joint body 1.1 and the annular support 2 to improve the aesthetics. In addition, the wing plate 1.3 can also form an enlarged joint body 1.1, which also improves the stability of the joint 1 after connection to a certain extent.

[0041] like Figure 4 As shown, when the annular support 2 and the connector 1 are installed in place, the protrusion 1.2 can be fully inserted into the inner cavity of the annular support 2. At this time, the end face of the annular support 2 is in contact with the surface of the connector body 1.1. That is to say, the width of the protrusion 1.2 is smaller than the width of the connector body 1.1. In this way, the connector 1 can be smoothly installed in place and form a limiting effect on the annular support 2, thereby preventing the annular support 2 from sliding along the direction of the protrusion 1.2 after being installed on the connector 1, thereby improving the connection stability between the connector 1 and the annular support 2.

[0042] like Figure 2-4 As shown, the height of the joint body 1.1 is less than or equal to the height of the annular support 2, so as to ensure that after the joint 1 and the annular support 2 are installed, the annular support 2 can be in contact with each other to achieve force transmission. It should be noted that, please refer to Figure 1 In addition to the protrusions 1.2 and the wing plates 1.3, other protruding structures may be provided on the joint body 1.1 to achieve the purpose of improving the strength, stability and aesthetics of the joint 1.

[0043] The present invention also provides a frame type frame, such as Figure 2 As shown, the annular support 2 is respectively connected with a cross beam 2.2, a longitudinal beam 2.1 and a column 2.3, and a frame unit is composed of four cross beams 2.2, four longitudinal beams 2.1, four columns 2.3 and eight joints 1. The frame unit in this embodiment is a rectangular parallelepiped frame structure. It should be noted that the positions of the cross beam 2.2 and the longitudinal beam 2.1 can be interchanged. It is just a difference in the name. The structure can be adjusted and replaced according to the actual use. That is to say, it is only for the convenience of explaining the specific structure of this embodiment, which cannot be a limitation on the structure of the present invention. Please refer to Figure 2 , the figure shows a frame structure composed of a frame unit, in which the connection structure is mainly used at the eight corners of the frame structure, please refer to Figure 4 The figure shows a frame-type frame structure composed of multiple frame units. Of course, the frame units in the figure can also be extended upward or on both sides to be arranged in multiple numbers. One or more frame units constitute the frame-type frame of this embodiment, wherein the connection structure is not only used at the eight corners, but also at any position where the cross beam 2.2, the longitudinal beam 2.1 and the column 2.3 are connected to each other. The application of the connection structure avoids the direct load-bearing of the joint 1, thereby greatly improving the load-bearing performance and stability of the frame-type frame.

[0044] Reference again Figure 2-4 The annular support 2 is formed integrally with the crossbeam 2.2, the longitudinal beam 2.1 and the column 2.3 respectively. At this time, the crossbeam 2.2 and the longitudinal beam 2.1 can be overlapped on the column 2.3, that is, the load-bearing components of this embodiment are the crossbeam 2.2, the longitudinal beam 2.1 and the column 2.3, and all gravity is avoided from directly acting on the joint 1, thereby improving the load-bearing performance and stability of the frame structure. Furthermore, the width of the longitudinal beam 2.1 is smaller than the width of the column 2.3 or the width of the crossbeam 2.2 is smaller than the width of the column 2.3, that is, one of the longitudinal beam 2.1 or the crossbeam 2.2 is smaller than the width of the column 2.3, which can make the crossbeam 2.2, the longitudinal beam 2.1 and the joint body 1.1 cover the entire surface of the column 2.3, thereby maximizing the use of the surface of the column 2.3, so that it provides sufficient supporting force, while also avoiding the situation of missing corners affecting the appearance.

[0045] like Figure 1-2 As shown, the column 2.3 is provided with a vertical mounting groove 2.3.1 on the side, the crossbeam 2.2 is provided with a transverse mounting groove 2.2.1 on the side, and the longitudinal beam 2.1 is provided with a longitudinal mounting groove 2.1.1 on the side. The vertical mounting groove 2.3.1, the transverse mounting groove 2.2.1 and the longitudinal mounting groove 2.1.1 are used to install the partition 5. The vertical partition 5 is used for partitioning, and the transverse partition 5 is mainly used for bearing. Each vertical mounting groove 2.3.1, the transverse mounting groove 2.2.1 and the longitudinal mounting groove 2.1.1 can be made by chip removal processing on the column 2.3, the crossbeam 2.2 and the longitudinal beam 2.1 respectively. At this time, the wall thickness of the column 2.3, the crossbeam 2.2 and the longitudinal beam 2.1 needs to reach a certain thickness. In order to reduce the amount of material used, this embodiment preferably adopts a thin-wall bending molding method, please refer to Figure 1-2 The vertical mounting groove 2.3.1, the horizontal mounting groove 2.2.1 and the longitudinal mounting groove 2.1.1 are formed by bending the outer wall thereof to form a "" shape, or by setting a second convex ridge 4 on the outer wall thereof (please refer to Figure 3 ), in the production Figure 3 The structural style shown, that is, after the second ridge 4 is set, according to the load-bearing needs, the groove width and height of the longitudinal mounting groove 2.1.1 at the position of the second ridge 4 can be set higher without changing the main body size of the longitudinal beam 2.1, so that it can accommodate a thicker horizontal partition 5, thereby improving the load-bearing capacity of the partition 5; the above methods will reduce the amount of material used, and can also ensure the supporting capacity and anti-bending deformation ability of the column 2.3, the cross beam 2.2 and the longitudinal beam 2.1 on the basis of using thin-walled parts. In order to adapt to the structural changes, the protrusion 1.2 is provided with a groove, which is used to avoid the above-mentioned "J" structure, so that the protrusion 1.2 can be smoothly inserted into the inner cavity of the column 2.3, the cross beam 2.2 and the longitudinal beam 2.1.

[0046] Please refer again Figure 3 , Figure 3 The cross-sectional view of the longitudinal beam 2.1 is shown, which can actually be called the cross-sectional view of the cross beam 2.2. For the sake of clarity, it is called the cross-sectional view of the longitudinal beam 2.1 here. The protruding height of the first ridge 3 is set according to the width of the protrusion 1.2, so that the interference fit of the protrusion 1.2 can be limited to the inner cavity of the longitudinal beam 2.1. At this time, a groove is provided on the side of the protrusion 1.2, and the two end faces of the groove are in contact with the first ridge 3, thereby forming a point contact in all directions. That is to say, the surface contact between the protrusion 1.2 and the inner wall surface of the longitudinal beam 2.1 is improved into point contact. The point contact can avoid the unstable position after the installation of the protrusion 1.2 caused by the uneven inner wall surface, and can also reduce the material consumption. It is also equivalent to setting a reinforcing rib. , ensuring the firmness when the wall thickness is reduced. What is important is that the reason why the present invention can be designed in the form of point contact is also based on the change of the stress condition of the joint 1. That is to say, since the joint 1 is no longer subjected to the main force, the main force-bearing parts are on the cross beams 2.2, the longitudinal beams 2.1 and the columns 2.3. Therefore, the joint can be improved into point contact. It should be noted that the above is only a preferred embodiment of the present invention. The wall thickness of the present invention can also be made relatively thick. In this case, the first ridge 3 will not be provided. When the above longitudinal beam 2.1 is applied to the cross beam 2.2 and placed on the front, the groove formed between the two second ridges 4 can be used to install the hinge, which is used to install the door leaf. In addition, please refer to Figure 2 , the groove on the left side of the middle column 2.3 can also be used to install a hinge, which is used to install a side-opening door.

[0047] like Figure 4 As shown, after the partition 5 is installed on the frame-type frame, each frame unit forms a storage bin that can accommodate items, and the storage bin can be used to store items such as urns. A door leaf can also be set on the front of each frame unit, i.e. the storage bin, and the door leaf can be closed after storing the items. Of course, the door leaf can also be provided with a door lock and other structures.

[0048] like Figure 5 As shown, set in Figure 3 The column 2.3 in the center of the frame body has a "J"-shaped structure on the four sides. Figure 5 As shown, Figure 3 The joint 1 structure is arranged at the center of the frame-type frame, and the joint 1 is provided with protrusions 1.2 on 6 faces. Figure 6It can be seen that the protrusion 1.2 at the bottom of the joint 1 is not provided with a groove, that is, after the protrusion 1.2 at the bottom of the frame-type frame center joint 1 is inserted into the inner cavity of the column 2.3, the end face of the "J"-shaped structure contacts the protrusion 1.2 (of course, the first convex ridge 3 can also be provided on the end face of the "J"-shaped structure) to form a limiting structure. Therefore, the groove of the protrusion 1.2 described above to avoid the "J"-shaped structure is not applicable to the connection structure in all positions, such as Figure 1 , 2 As shown in Figures 6 and 7, the protrusion 1.2 does not necessarily have an open groove unless necessary. In this way, under the premise of reducing the load-bearing requirements of the joint 1 itself, the protrusion 1.2 can be designed to be smaller. At this time, there is no need to avoid structures such as the first ridge 3 provided on the inner wall of the cross beam 2.2, the longitudinal beam 2.1 and the column 2.3. Therefore, the protrusion 1.2 can be set in a closed circle form. Even if the volume is reduced, it can still ensure that it has a certain connection strength, and the side of the protrusion 1.2 and the end of the first ridge 3 are installed by interference fit to achieve the best installation strength.

[0049] The present invention also discloses a method for installing a frame-type frame, comprising the following steps:

[0050] (1) Insert the protrusion on the joint into the inner cavity of the crossbeam and the longitudinal beam. Since the protrusion and the crossbeam and the longitudinal beam have an interference fit, it is necessary to knock the joint or the crossbeam and the longitudinal beam to facilitate smooth installation. In addition, in order to ensure stable and firm installation, the end faces of the crossbeam and the longitudinal beam need to be in contact with the surface of the joint body.

[0051] (2) Place the partition in the transverse mounting groove and the longitudinal mounting groove. It should be noted that the present invention does not limit the matching relationship between the partition and the transverse mounting groove and the longitudinal mounting groove. That is to say, it can adopt a clearance fit method or a transition or interference fit method. If the material of the partition is relatively hard and can provide a large load-bearing capacity (such as steel plate, aluminum plate or aluminum alloy plate, etc.), it can be inserted into the transverse mounting groove or the vertical mounting groove by means of interference fit. At this time, a high stability can be guaranteed. If it is a relatively weak material (such as plastic, etc.), a clearance fit method can be adopted to reduce the damage to the partition during its installation process. After the above installation process, a bottom structure including a crossbeam, a longitudinal beam, a joint and a partition is formed;

[0052] (3) Insert the column into the protrusion. Similarly, it is necessary to knock the joint or the column and make the end surface of the column contact with the surface of the joint body to improve stability and firmness;

[0053] (4) Place the partition in the vertical installation groove. The partition is inserted from top to bottom into the vertical installation grooves opposite to the two columns. The lower part of the partition is inserted into the horizontal installation groove or the vertical installation groove. Similarly, the matching mode between the partition and the vertical installation groove can be clearance fit, transition fit or interference fit;

[0054] (5) Install the upper layer of cross beams and longitudinal beams according to the method of step (1), and install the upper layer of partitions according to the method of step (2);

[0055] (6) When the structure of the frame needs to be expanded, repeat the above steps (1) to (5). Figure 4 As shown, a frame-type frame structure is formed with multiple frame units.

[0056] The present invention uses specific examples to illustrate the principles and implementation methods of the present invention. The above examples are only used to help understand the method and core ideas of the present invention. At the same time, for those skilled in the art, according to the ideas of the present invention, there will be changes in the specific implementation methods and application scope. In summary, the content of this specification should not be understood as limiting the present invention.
