Detailed ways

The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, but not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

The purpose of the present invention is to provide a connection structure for a frame-type frame body, a frame-type frame body and an installation method, so as to solve the problems existing in the prior art, make beams or columns in various directions carry out load-bearing, and reduce the need for joints. The strength requirements significantly improve the load-bearing performance and stability of the storage rack structure.

In order to make the above objects, features and advantages of the present invention more clearly understood, the present invention will be described in further detail below with reference to the accompanying drawings and specific embodiments.

As shown in Figures 1-2, 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 cuboid structure, but in fact, the joint body 1.1 can be any shape, such as spherical, prismatic, polyhedral, as long as it can ensure that the adjacent protrusions 1.2 are perpendicular to each other. Yes, the structure that cooperates with the protrusion 1.2 is the annular support 2. The number of the annular support 2 corresponds to the number of the protrusions 1.2. The protrusion 1.2 is completely inserted into the inner cavity of the annular support 2. The protrusion 1.2 is connected with the annular support 2. It is explained 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. The supports 2 are connected, and, after the above-mentioned installation is completed, the outer walls of the adjacent annular supports 2 are attached, the lateral annular supports 2 are attached to the outer walls of the vertical annular supports 2, and the lateral annular supports 2 are attached to the lateral The outer walls of the annular supports 2 are also attached to each other, that is to say, each annular support 2 can transmit force to each other, and the joint 1 only plays the role of connection, it does not bear the effect of gravity, which can significantly reduce the friction. Joint strength requirements.

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

As shown in FIG. 1 and FIG. 3 , the inner surface of the annular support 2 is provided with a first convex rib 3 protruding inwardly. In contact with the protrusion 1.2, at this time, the first rib 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 arrangement of the first rib 3 can reduce the The wall thickness of the annular support 2 can significantly reduce the material consumption of the annular support 2, and at the same time, the first convex rib 3 of the annular support 2 arranged vertically can also form an effective support for the annular support 2 arranged horizontally on its upper part, The supporting capacity of the annular support 2 is improved. In fact, the first rib 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 .

As shown in Figure 1-2, the joint body 1.1 is provided with a wing plate 1.3. The side of the wing plate 1.3 is parallel to the side surface of the annular support 2. Please refer to Figure 2 and Figure 3. The wing plate 1.3 is set on the side facing the operator. At this time, the wing plate 1.3 can block 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 joint body 1.1 to a certain extent. stability.

As shown in Figure 4, when the annular support 2 and the joint 1 are installed in place, the protrusion 1.2 can be completely inserted into the inner cavity of the annular support 2, and the end surface of the annular support 2 is also in contact with the surface of the joint body 1.1. That is to say, the width of the protrusion 1.2 is smaller than the width of the joint body 1.1. In this way, the joint 1 can be smoothly installed in place and form a limiting effect on the annular support 2, which also prevents the annular support 2 from being installed to the joint 1. It can also slide along the direction of the protrusion 1.2 after being up, thereby improving the connection stability between the joint 1 and the annular support 2.

As shown in Figure 2-4, the height of the joint body 1.1 is less than or equal to the height of the annular support 2 to ensure that after the joint 1 and the annular support 2 are installed, the mutual contact between the annular supports 2 can be ensured to achieve force transmission. However, please refer to FIG. 1 , in addition to the protrusions 1.2 and the wings 1.3 on the joint body 1.1, other protruding structures can also be arranged to achieve the purpose of improving the strength, stability and aesthetics of the joint 1 .

The present invention also provides a frame-type frame. As shown in FIG. 2 , the annular support 2 is respectively connected with a beam 2.2, a longitudinal beam 2.1 and a column 2.3. Eight joints 1 form a frame unit. The frame unit in this embodiment is a cuboid frame structure. It should be noted that the positions of the beam 2.2 and the longitudinal beam 2.1 can be interchanged, but the name is different, and the structure is based on the actual use. It can be adjusted and replaced, that is to say, it is only to facilitate the description of the specific structure of this embodiment, and it cannot be a limitation to the structure of the present invention. Please refer to FIG. 2, which is a frame-type frame structure composed of a frame unit, wherein, The connection structure is mainly applied to the positions of the eight corners of the frame-type frame structure. Please refer to Figure 4, which is a frame-type frame structure composed of multiple frame units. Of course, the frame units in this figure can also be upwards. Or the two sides are expanded to set up multiple, one or more frame units constitute the frame type frame body of this embodiment, wherein, the connection structure is not only used in the eight corner positions, but also used in any beam 2.2, The position where the longitudinal beam 2.1 and the upright column 2.3 are connected to each other, the application of this connection structure avoids the direct load-bearing of the joint 1, and greatly improves the load-bearing performance and stability of the frame-type frame.

Referring to Figure 2-4 again, the annular support 2 is integrally formed with the beam 2.2, the longitudinal beam 2.1 and the column 2.3. At this time, the beam 2.2 and the longitudinal beam 2.1 can be overlapped on the column 2.3, that is to say, the load-bearing of this embodiment is The components are the beam 2.2, the longitudinal beam 2.1 and the column 2.3. All the gravity avoids directly acting on the joint 1, thereby improving the load-bearing performance and stability of the frame structure. Further, the width of the longitudinal beam 2.1 is smaller than that of the column. The width of 2.3 or the width of the beam 2.2 is smaller than the width of the column 2.3, that is, the width of the longitudinal beam 2.1 or the beam 2.2 is smaller than that of the column 2.3, which can make the beam 2.2, the longitudinal beam 2.1 and the joint body 1.1 cover the entire column 2.3 surface, so as to maximize the use of the surface of the column 2.3, so that it can provide sufficient supporting force, and at the same time, it also avoids the situation of missing corners affecting the appearance.

As shown in Figure 1-2, the column 2.3 is provided with a vertical installation groove 2.3.1 on the side, the beam 2.2 is provided with a lateral installation groove 2.2.1 on the side, and the longitudinal beam 2.1 is provided with a longitudinal installation groove 2.1 on the side. 1. The vertical installation slot 2.3.1, the horizontal installation slot 2.2.1 and the vertical installation slot 2.1.1 are used to install the partition 5, the vertical partition 5 is used for separation, and the horizontal partition 5 is mainly used for bearing, Each vertical installation groove 2.3.1, horizontal installation groove 2.2.1 and vertical installation groove 2.1.1 can be made by chip removal processing on the column 2.3, the beam 2.2 and the longitudinal beam 2.1 respectively. At this time, the column 2.3 is required. , the wall thickness of the beam 2.2 and the longitudinal beam 2.1 reaches a certain thickness. In order to reduce the amount of material, this embodiment preferably adopts the method of thin-wall bending. Please refer to Figure 1-2, vertical installation slot 2.3.1, horizontal installation The groove 2.2.1 and the longitudinal installation groove 2.1.1 are formed by bending the outer wall to form a zigzag shape, or by setting the second rib 4 on the outer wall where it is located (please refer to Figure 3). The structural style shown is that after the second rib 4 is installed, according to the load-bearing needs, the groove width and height of the longitudinal installation groove 2.1.1 at the position of the second rib 4 can be set without changing the size of the main body of the longitudinal beam 2.1. higher, so that it can accommodate thicker transverse partitions 5, so as to improve the load-bearing capacity of the partitions 5; the above methods will reduce the amount of material, and can also ensure the use of thin-walled parts. In order to adapt to the change of the structure, the support capacity of the beam 2.2 and the longitudinal beam 2.1 and the ability to resist bending deformation, the protrusion 1.2 is provided with a groove, which is used to avoid the above-mentioned formed several-character structure, so that the protrusion 1.2 can be Smoothly inserted into the inner cavity of column 2.3, beam 2.2 and longitudinal beam 2.1.

Please refer to FIG. 3 again. FIG. 3 shows a cross-sectional view of the longitudinal beam 2.1. In fact, it can also be called a cross-sectional view of the cross beam 2.2. The protruding height of the edge 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. The two end faces will be in contact with the first convex rib 3, thus forming the form of 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 to a point contact, and the point contact can avoid the inner wall. The unevenness of the surface caused by the installation of the bulge 1.2 after the position is unstable, it can also reduce the amount of material, and it is also equivalent to setting up a reinforcing rib to ensure the firmness in the case of a reduced wall thickness. It is important that this The reason why the invention can be designed in the form of point contact is also based on changing the force of the joint 1, that is to say, since the joint 1 is not under the action of the main force, the main force-bearing parts are in each beam 2.2, longitudinal beam 2.1 and column 2.3, therefore, the joint can be improved into point contact; it should be noted that the above is only the preferred embodiment of the present invention, and the wall thickness of the present invention can also be made into a relatively thick case, which will not Set the first ridge 3; when the above-mentioned 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 center column 2.3 in the figure can also be used to install a hinge, which is used to install a side door.

As shown in FIG. 4 , after the frame-type frame body is installed with the partition 5, each frame unit forms a storage bin capable of accommodating items, and the storage bin can be used to store items such as urns. The front of the storage bin can also be provided with a door leaf, which can be closed after storing items. Of course, the door leaf can also be provided with a door lock and other structures.

As shown in Figure 5, the upright column 2.3 is arranged in the center of the frame type frame body in Figure 3, and the column 2.3 is provided with a zigzag structure on four sides, as shown in Figure 5, which is arranged in the center of the frame type frame body in Figure 3 According to the structure of the joint 1, the joint 1 is provided with protrusions 1.2 on 6 faces. It can be seen from Figure 6 that the protrusion 1.2 at the lower part of the joint 1 is not provided with grooves, that is to say, the center joint of the frame type frame 1. After the lower protrusion 1.2 is inserted into the inner cavity of the column 2.3, the end face of the zigzag structure is in contact with the protrusion 1.2 (of course, the end face of the zigzag structure can also be provided with a first ridge 3) to form a limiting structure, so , the above-mentioned convex 1.2 groove avoidance zigzag structure is not applicable to the connection structure in all positions. As shown in Figures 1, 2, and 6, the convex 1.2 may not necessarily be provided with an open groove unless necessary. In this way, on 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 the structures such as the first rib 3 set on the inner wall of the beam 2.2, the longitudinal beam 2.1 and the column 2.3. , therefore, the protrusion 1.2 can be set in the form of a closed circumference, 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 rib 3 are installed with interference fit. Optimum installation strength.

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

(1) Insert the protrusion on the joint into the inner cavity of the beam and the longitudinal beam. Since the matching relationship between the protrusion and the beam and the longitudinal beam is an interference fit, at this time, it is necessary to tap the joint or the beam and the longitudinal beam to facilitate the It can be installed smoothly, and in order to install stably and firmly, it is necessary to make the end faces of the beams and the longitudinal beams contact the surface of the joint body;

(2) Place the partition plate in the horizontal installation groove and the vertical installation groove. It should be noted that the present invention does not limit the matching relationship between the partition plate and the horizontal installation groove and the vertical installation groove. That is to say, it can use For clearance fit, transition or interference fit can also be used. If the material of the partition is relatively hard and will provide a larger bearing capacity (such as steel plate, aluminum plate or aluminum alloy plate, etc.), it can be By means of interference fit, it is knocked and inserted into the horizontal installation slot or the vertical installation slot. At this time, high stability can be guaranteed. If it is a relatively weak material (such as plastic, etc.), a clearance fit can be used. In order to reduce the damage to the clapboard during the installation process, a bottom structure including beams, longitudinal beams, joints and clapboards is formed after the above-mentioned installation process;

(3) Insert the column into the protrusion, and similarly, it is necessary to tap the joint or the column, and make the end face of the column contact the surface of the joint body to improve stability and firmness;

(4) Place the baffle in the vertical installation slot, insert the baffle into the vertical installation slot opposite to the two columns from top to bottom, and insert the lower part of the baffle into the horizontal installation slot or the vertical installation slot, the same , the matching mode of the partition plate and the vertical installation groove can be clearance fit, transition fit or interference fit;

(5) Install the beams and longitudinal beams of the upper layer according to the method of step (1), and install the clapboard of the upper layer according to the method of step (2);

(6) When the structure of the frame-type frame needs to be expanded, the above steps (1)-(5) are repeated, as shown in FIG. 4 , to form a frame-type frame structure of multiple frame units.

In the present invention, specific examples are used to illustrate the principles and implementations of the present invention, and the descriptions of the above embodiments are only used to help understand the method and the core idea of the present invention; There will be changes in the specific implementation manner and application scope of the idea of the invention.
