[0043] Please refer to Figure 1 , Figure 1 A schematic structural diagram of a bracket assembly 100 in an embodiment of the present application is shown. The embodiment of the present application provides a bracket assembly 100 including a bracket body 110 and a blocking member 120 .
[0044] The support body 110 is a main component used to form a component. The support body 110 can be constructed in a plate shape. Multiple components are connected to form a connection node. The component can be a steel component or a component of other materials. Figure 2 and Figure 3 , Figure 2 Shows Figure 1 A schematic structural diagram of the support body 110 of the middle support assembly 100, Figure 3 Shows Figure 2 In the partial enlarged structural schematic diagram at A in the middle, a mounting hole k for mounting a connector is provided on the bracket body 110 along the first direction F1. The connector (not shown in the figure) is a component used to connect the multiple components mentioned above. The mounting hole k includes a first hole segment k1 and a second hole segment k2 arranged in sequence along the second direction F2. Along the second direction F2, the cross-sectional area of the second hole segment k2 is smaller than the cross-sectional area of the first hole segment k1. That is, the connector can first enter the first hole segment k1 with a larger space, and then move to the second hole segment k2, so as to facilitate the installation of the connector in the second hole segment k2. The longitudinal direction of the mounting hole k is the second direction F2, and the width direction of the mounting hole k is the third direction F3. The first direction F1, the second direction F2 and the third direction F3 are perpendicular to each other. In this way, the mounting hole k is arranged roughly in a T-shape.
[0045] The blocking member 120 is a component used to block the connecting member and can limit the connecting member. The blocking member 120 is snapped into the second hole segment k2. Along the second direction F2, the cross-sectional area of the blocking member 120 is smaller than the cross-sectional area of the first hole segment k1. That is, the blocking member 120 can first enter the first hole segment k1 with a larger space, and then move to the second hole segment k2, so as to facilitate the installation of the blocking member 120 in the second hole segment k2. One end of the blocking member 120 along the second direction F2 abuts against the inner wall of the end of the second hole segment k2 away from the first hole segment k1, and the other end of the blocking member 120 along the second direction F2 is used to abut against the connecting member located in the second hole segment k2.
[0046] It should be noted that, according to the connection requirements of different components, the connector has a target position located in the second hole segment k2. When the connector is in the target position, the space defined by the connector and the inner wall of the end of the second hole segment k2 away from the first hole segment k1 is filled by the blocking member 120. That is, the blocking member 120 abuts between the connector and the inner wall of the end of the second hole segment k2 away from the first hole segment k1. When in use, the second direction F2 can be parallel to the direction of gravity, or it can be set at an angle to the direction of gravity. When the second direction F2 is set at an angle to the direction of gravity, the second direction F2 can be regarded as an obliquely downward direction. In other words, the supporting force provided by the blocking member 120 to the connector can prevent the connector from moving downward or obliquely downward, thereby achieving the limit of the connector.
[0047] It is understandable that, in order to facilitate the installation of the connector, the mounting hole k is usually set larger or longer, and a flat washer or a spring washer is used to increase the friction between the connector and the bracket body 110. However, in such a process, due to the mounting hole k being too large or too long, the connector has a tendency to slide down relative to the bracket body 110 under the action of external forces and the deadweight of the connection node. When the force during the slide is greater than the friction force mentioned above, the connector will slide down along the mounting hole k, thereby causing the connector to be misaligned, thereby affecting the reliability and use of the connection node.
[0048] In the embodiment of the present application, by providing the first hole section k1 and the second hole section k2 on the bracket body 110, the blocking member 120 and the connecting member can enter the second hole section k2 through the first hole section k1, which facilitates the installation of the blocking member 120 and the connecting member. By installing the blocking member 120 in the second hole section k2, and making the blocking member 120 abut between the inner wall of the end of the second hole section k2 away from the first hole section k1 and the connecting member, the connecting member installed in the second hole section k2 can be limited, thereby improving the situation that the connecting member moves toward the end of the second hole section k2 away from the first hole section k1, thereby improving the reliability and safety of the steel structure connection.
[0049] In some embodiments, please refer to Figure 1 , and combined with reference Figure 4 and Figure 5 , Figure 4 Shows Figure 1 One of the partial enlarged structural diagrams at B in the middle, Figure 5 Shows Figure 1 The second schematic diagram of the local enlarged structure at B in the middle, Figure 5 The dotted line in the figure shows a part of the second hole segment k2 blocked by the blocking member 120. The blocking member 120 includes a plurality of sub-blocking members 120a that are clamped to the second hole segment k2. All sub-blocking members 120a abut in sequence along the second direction F2. The sub-blocking member 120a farthest from the first hole segment k1 abuts against the inner wall of the end of the second hole segment k2 farthest from the first hole segment k1, and the sub-blocking member 120a closest to the first hole segment k1 is used to abut against the connecting member located in the second hole segment k2.
[0050] Specifically, the sub-blocking member 120a closest to the first hole segment k1 is defined as the first sub-blocking member 121, and the sub-blocking member 120a farthest from the first hole segment k1 is defined as the second sub-blocking member 122. The first sub-blocking member 121 is used to abut against the connecting member located in the second hole segment k2, and the second sub-blocking member 122 abuts against the inner wall of the end of the second hole segment k2 farthest from the first hole segment k1.
[0051] The number of sub-blocking members 120a and the size of the sub-blocking members 120a along the second direction F2 can be determined according to the target position of the connecting member mentioned above, as long as the blocking member 120 formed by all sub-blocking members 120a can limit the connecting member at the target position, and no specific limitation is made here. The sizes of all sub-blocking members 120a along the second direction F2 can be the same or different. Figure 4 and Figure 5 As an example, a situation where two sub-blocking members 120 a are provided is illustrated, and the two sub-blocking members 120 a are respectively a first sub-blocking member 121 and a second sub-blocking member 122 .
[0052] In this way, by configuring the blocking member 120 to include a plurality of sub-blocking members 120a, the number and size of the sub-blocking members 120a can be selected according to specific usage conditions, thereby improving the flexibility of the blocking member 120, further adapting to the connecting member and limiting the connecting member to the target position. In this way, the flexibility and adaptability of the installation process and the connection process are improved as a whole.
[0053] In some embodiments, please refer to Figure 4 and Figure 5 , and combined with reference Figure 6 , Figure 6 Shows Figure 1 A schematic structural diagram of the first sub-blocking member 121 of the middle bracket assembly 100, wherein the first sub-blocking member 121 has a first surface s1 disposed toward the first hole segment k1 at one end thereof that is away from the second sub-blocking member 122. A recessed portion a is disposed on the first surface s1 and is recessed in a direction away from the first hole segment k1, and the recessed portion a penetrates the first sub-blocking member 121 along the first direction F1.
[0054] The recessed portion a can be used to accommodate part of the connector, and the recessed portion a forms a limiting space for the connector. In this way, it is beneficial to install the connector with the help of the recessed portion a, and the limiting effect on the connector can be achieved more stably.
[0055] In some embodiments, please refer to Figure 6 , the inner wall of the recessed portion a is configured as an arc surface. The inner wall of the recessed portion a is the first inner wall b1, and the first inner wall b1 is the portion of the first surface s1 located at the recessed portion a. The first inner wall b1 is configured as an arc surface. Further, the orthographic projection of the first inner wall b1 on the reference plane is an arc line, and the reference plane is a plane perpendicular to the first direction F1.
[0056] Since the connector can be a cylindrical structure with a threaded structure, the outer peripheral surface of the connector can be roughly regarded as an arc surface. Therefore, by configuring the inner wall of the recessed portion a as an arc surface, it can be further adapted to the shape of the connector, increasing the contact area between the inner wall of the recessed portion a and the outer peripheral surface of the connector, thereby being more conducive to achieving the limit of the connector.
[0057] In some embodiments, please refer to Figures 3 to 5 , and combined with reference Figure 7 , Figure 7 Shows Figure 1 One of the structural schematic diagrams of the second sub-blocking member 122 of the middle bracket assembly 100, the inner wall of the second hole segment k2 away from one end of the first hole segment k1, and the end surface of the second sub-blocking member 122 away from the first sub-blocking member 121 are constructed as arc surfaces that adapt to each other.
[0058] Specifically, the inner wall of the end of the second hole segment k2 away from the first hole segment k1 is the second inner wall b2, the end surface of the second sub-blocking member 122 away from the first sub-blocking member 121 is the second surface s2, and the second inner wall b2 and the second surface s2 are configured as circular arc surfaces that fit each other. The orthographic projections of the second inner wall b2 and the second surface s2 on the reference surface are both circular arcs. The second inner wall b2 may be a convex circular arc surface and the second surface s2 may be a concave circular arc surface, or the second inner wall b2 may be a concave circular arc surface and the second surface s2 may be a convex circular arc surface. The configuration may be made according to the specific usage, and no specific limitation is made here.
[0059] In this way, by constructing the surfaces of the second sub-blocking member 122 and the second hole segment k2 that cooperate with each other as arc surfaces that adapt to each other, it is not only beneficial to increase the contact area between the two, but also can restrict the two from each other in the third direction F3, thereby allowing the second sub-blocking member 122 to be more stably engaged in the second hole segment k2.
[0060] In some embodiments, please refer to Figures 3 to 5 , Figure 7 The inner wall of the second hole segment k2 at one end away from the first hole segment k1 is configured as an arc surface protruding away from the first hole segment k1. The end surface of the second sub-blocking member 122 away from the first hole segment k1 is configured as an arc surface protruding away from the first hole segment k1.
[0061] Specifically, the second inner wall b2 is configured as an arc surface that is convexly arranged in a direction away from the first hole segment k1, and the second surface s2 is configured as an arc surface that is convexly arranged in a direction away from the first hole segment k1. That is, the second inner wall b2 is a concave arc surface, and the second surface s2 is a convex arc surface. In this way, the second inner wall b2 and the second surface s2 are arranged in a substantially U-shape.
[0062] In this way, the structures of the second inner wall b2 and the second surface s2 can be flexibly set according to the usage. When the second inner wall b2 is a concave arc surface and the second surface s2 is a convex arc surface, it is not only easy to process and manufacture, but also easy to form a structure that partially surrounds the second sub-blocking member 122 through the second hole segment k2, which is more conducive to improving the stability of the second sub-blocking member 122 when it is installed in the second hole segment k2.
[0063] In some embodiments, please refer to Figures 4 to 6 , combined with reference Figure 8 , Figure 8 Shows Figure 1 The second structural schematic diagram of the second sub-blocking member 122 of the middle bracket assembly 100, along the second direction F2, the side surfaces of two adjacent sub-blocking members 120a facing each other are both constructed as planes and abut against each other.
[0064] Specifically, for example, the blocking member 120 includes two sub-blocking members 120a, and the two sub-blocking members 120a are respectively a first sub-blocking member 121 and a second sub-blocking member 122. Figure 6 As shown, the side surface of the first sub-blocking member 121 facing the second sub-blocking member 122 is the third surface s3. Figure 8As shown, the side surface of the second sub-blocking member 122 facing the first sub-blocking member 121 is the fourth surface s4. The third surface s3 and the fourth surface s4 are both constructed as planes and abut each other. The third surface s3 and the fourth surface s4 are parallel to each other. The third surface s3 and the fourth surface s4 can be perpendicular to the second direction F2. Of course, the third surface s3 and the fourth surface s4 can also be set at a preset angle with the second direction F2, that is, the third surface s3 and the fourth surface s4 can be tilted relative to the second direction F2. The third surface s3 and the fourth surface s4 can be determined according to the relationship between the second direction F2 and the gravity direction during specific use, forming a surface tilted relative to the gravity direction or a surface perpendicular to the gravity direction, thereby meeting different stability requirements.
[0065] Thus, by configuring the surfaces of two adjacent sub-blocking members 120a facing each other to be flat, it is convenient to sequentially install the sub-blocking members 120a and improve the stability of the abutment between the two adjacent sub-blocking members 120a, and it is also convenient for processing and manufacturing.
[0066] Of course, in other embodiments, the third surface s3 and the fourth surface s4 may also be set as arc surfaces, and the orthographic projections of the third surface s3 and the fourth surface s4 on the reference surface are both straight lines. This can be set according to specific usage requirements and is not specifically limited here.
[0067] In some embodiments, please refer to Figures 4 to 8 A snap-fitting groove c is provided on the side wall of the sub-blocking member 120a, which matches with the hole wall of the second hole section k2.
[0068] Specifically, Figure 6 For example, the outer peripheral surface of the first sub-blocking member 121 except the first surface s1 and the third surface s3 is a side wall, and a clamping groove c is provided on the side wall of the first sub-blocking member 121. Figure 7 and Figure 8 For example, the outer peripheral surface of the second sub-blocking member 122 except the fourth surface s4 and the second surface s2 is a side wall, and a snap-in groove c is provided on the side wall of the second sub-blocking member 122. Of course, a snap-in groove c can also be provided on the second surface s2 of the second sub-blocking member 122, and the snap-in groove c located on the second surface s2 is connected to the snap-in groove c located on the side wall of the second sub-blocking member 122, that is, the bottom wall of the snap-in groove c located on the second surface s2 is connected to the snap-in groove c located on the side wall of the second sub-blocking member 122. Part of the second surface s2 constitutes the bottom wall of the snap-in groove c located on the second surface s2. In this way, it is beneficial to improve the stability of the snap-in fit between the second sub-blocking member 122 and the second hole segment k2.
[0069] In this way, by providing the engaging groove c on the side wall of the sub-blocking member 120 a , it is convenient to install the sub-blocking member 120 a in the second hole section k2 , thereby realizing the detachable connection between the sub-blocking member 120 a and the bracket body 110 .
[0070] In some embodiments, the material of the blocking member 120 includes one of carbon steel and aluminum alloy; and / or the material of the bracket body 110 includes one of carbon steel and aluminum alloy. It can be understood that carbon steel and aluminum alloy are materials with durability and certain strength, which help to improve the service life of the bracket assembly 100. Of course, the material of the blocking member 120 and the material of the bracket can be the same or different, and the material of the blocking member 120 and the material of the bracket can also be other materials with durability and certain strength, which are not specifically limited here.
[0071] Based on the same inventive concept, the embodiment of the present application provides a connection node, including a first component, a second component and a connector connecting the first component and the second component, wherein at least one of the first component and the second component is configured as the bracket assembly 100 in any of the above embodiments.
[0072] The first component and the second component may both be steel components. The connector may be a component having a threaded structure, and the first component and the second component may be fixedly connected by threaded connection. The first component may be configured as the bracket assembly 100, the second component may be configured as the bracket assembly 100, or both the first component and the second component may be configured as the bracket assembly 100, and no specific limitation is made here.
[0073] The related advantages and related implementation methods of the bracket assembly 100 are also possessed by the connection node provided in the embodiment of the present application, and will not be described in detail here.
[0074] The technical features of the above-described embodiments may be arbitrarily combined. To make the description concise, not all possible combinations of the technical features in the above-described embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.
[0075] The above-described embodiments only express several implementation methods of the present application, and the descriptions thereof are relatively specific and detailed, but they cannot be construed as limiting the scope of the patent application. It should be pointed out that, for a person of ordinary skill in the art, several variations and improvements can be made without departing from the concept of the present application, and these all belong to the protection scope of the present application. Therefore, the protection scope of the patent application shall be subject to the attached claims.
