[0035] The embodiments of the present invention are described in detail below. The embodiments described with reference to the accompanying drawings are exemplary. Figure 1 and Figure 2 The connector 100 according to the first embodiment of the utility model is described. The connector 100 can be used for the frame 200. However, it is not limited thereto. In the following description of the present application, the connector 100 is described in detail by taking the first frame 201 and the second frame 202 used to connect the frame 200 as an example.

[0036] like Figure 1 As shown, the connecting piece 100 for the frame 200 according to the first embodiment of the utility model includes a first connecting portion 1 and a second connecting portion 2 .

[0037] Specifically, the first connecting portion 1 is arranged along a first direction (eg Figure 1The first connecting portion 1 extends in the second direction (eg, Figure 1 At least one first connecting hole 11 is formed on one side side of the front-to-back direction (as shown), the second direction is perpendicular to the first direction, the second connecting part 2 is connected to one end of the first connecting part 1, the second connecting part 2 extends along the second direction, and at least one second connecting hole 21 is formed on one side side of the second connecting part 2 along the first direction.

[0038] For example, in Figure 1 In the example, the first connection hole 11 is formed on the front side of the first connection part 1, the front end of the second connection part 2 is connected to the right end of the first connection part 1, and the second connection hole 21 is formed on the right side of the second connection part 2. Of course, the first connection hole 11 can also be formed on the rear side of the first connection part 1, and the second connection hole 21 can be formed on the left side of the second connection part 2. The cross-sectional shape of the connector 100 is generally "L"-shaped.

[0039] With such arrangement, the structure of the connector 100 is simple, which is convenient for the production of the connector 100, thereby improving the production efficiency of the connector 100. Moreover, it is also convenient for the transportation and use of the connector 100. When the connector 100 is used for the frame 200, the adjacent first frame 201 and the second frame 202 of the frame 200 can be assembled into one by the first connecting portion 1 and the second connecting portion 2. Compared with the frame connected by welding in the conventional technology, the assembly is convenient and the assembly yield is high, thereby improving the assembly efficiency of the frame 200 and the connector 100, and also facilitating the disassembly of the connector 100 and the frame 200. In addition, the cost of assembling the frame 200 is reduced, the production cost of the frame assembly 300 is reduced, and the stability of the frame assembly 300 is improved, thereby extending the service life of the frame assembly 300. Moreover, the aesthetics of the frame 200 is also improved. In addition, by pre-setting the first connecting hole 11, the first connecting part 1 is conveniently connected to the corresponding first frame 201, and by pre-setting the second connecting hole 21, the second connecting part 2 is conveniently connected to the corresponding second frame 202, which is beneficial to the rapid assembly of the connecting member 100 and the frame 200. In addition, the frame 200 is not easily deformed during the assembly process, thereby extending the service life of the frame 200.

[0040] According to the connector 100 for the frame 200 of the utility model, the connector 100 has a simple structure and is easy to produce, thereby improving the production efficiency of the connector 100. Moreover, it is also convenient to transport and use the connector. When the connector 100 is used for the frame 200, the adjacent first frame 201 and the second frame 202 of the frame 200 can be assembled into one by the first connecting portion 1 and the second connecting portion 2, the assembly operation is convenient, and the assembly yield is high, thereby improving the assembly efficiency of the frame 200 and the connector 100, and also facilitating disassembly. In addition, the aesthetics of the frame 200 is also improved. In addition, the first connecting hole 11 and the second connecting hole 21 facilitate the quick assembly of the connector 100 and the frame 200, and the frame 200 is not easily deformed during the assembly process, thereby extending the service life of the frame 200.

[0041] According to some embodiments of the present invention, referring to Figure 1 The first connecting portion 1 has a first groove 12, and the first groove 12 is along the third direction (for example Figure 1 The third direction, the first direction (i.e., the left-right direction), and the second direction (i.e., the front-back direction) are orthogonal. Figure 1 In the example, the first groove 12 opens upward. In this way, the first groove 12 reduces the material usage of the first connecting part 1, thereby reducing the production cost of the first connecting part 1, and further reducing the production cost of the connecting piece 100. Moreover, the weight of the first connecting part 1 is also reduced, which facilitates the transportation and use of the connecting piece 100. At the same time, the first connecting part 1 has a certain structural strength, which is beneficial to the connection and coordination between the first connecting part 1 and the first frame 201. In addition, the formation of the first groove 12 reduces the difficulty of forming the first connecting hole 11, thereby facilitating the production of the connecting piece 100 and improving the production rate of the connecting piece 100. For example, the first groove 12 can also be opened downward (not shown in the figure).

[0042] According to other embodiments of the present invention, Figure 1 The second connecting portion 2 has a second groove 22, one side of the second groove 22 along the third direction (i.e., the up-down direction) is open, and the third direction, the first direction (i.e., the left-right direction) and the second direction (i.e., the front-back direction) are orthogonal. Figure 1In the example, the second groove 22 opens upward. In this way, the second groove 22 reduces the material usage of the second connecting part 2, thereby reducing the production cost of the second connecting part 2, and further reducing the production cost of the connecting piece 100. Moreover, the weight of the second connecting part 2 is also reduced, thereby facilitating the transportation and use of the connecting piece 100. At the same time, the second connecting part 2 has a certain structural strength, which is beneficial to the connection and cooperation between the second connecting part 2 and the second frame 202. In addition, the formation of the second groove 22 reduces the difficulty of forming the second connecting hole 21, thereby facilitating the production of the connecting piece 100 and improving the production rate of the connecting piece 100. For example, the second groove 22 may also be opened downward (not shown).

[0043] According to some further embodiments of the present invention, referring to Figure 1 , the first connecting part 1 has a first groove 12, and one side of the first groove 12 along the third direction (i.e., the up and down direction) is open. At the same time, the second connecting part 2 has a second groove 22, and one side of the second groove 22 along the third direction is open. In this way, while ensuring the structural strength of the connecting member 100, the material usage of the connecting member 100 is greatly reduced, thereby further reducing the production cost of the connecting member 100. Moreover, the weight of the connecting member 100 is also greatly reduced, which is further conducive to the transportation and use of the connecting member 100. In addition, the production difficulty of the first connecting hole 11 and the second connecting hole 21 is also reduced, thereby improving the production efficiency of the connecting member 100. It should be noted that the open sides of the first groove 12 and the second groove 22 can be located on the same side of the connecting member 100, or can be located on the upper and lower sides of the connecting member 100 respectively.

[0044] Further, refer to Figure 1 , when the first connection part 1 has the first groove 12 and the second connection part 2 has the second groove 22, the first groove 12 and the second groove 22 are connected. Figure 1 In the example, the right end of the first groove 12 is connected to the front end of the second groove 22. Therefore, in the process of forming the first groove 12 and the second groove 22, it is avoided to control the distance between the first groove 12 and the second groove 22, thereby reducing the difficulty of producing the first groove 12 and the second groove 22, thereby improving the production efficiency of the connection part. In addition, it is also avoided to use other components to separate the first groove 12 and the second groove 22, thereby further reducing the material consumption of the connector 100, thereby reducing the production cost of the connector 100.

[0045] According to some embodiments of the present invention, referring to Figure 1 When the first connection part 1 has the first groove 12 and the second connection part 2 has the second groove 22, the first groove 12 and the second groove 22 are open on the same side along the third direction (ie, the up-down direction). Figure 1 In the example, the first groove 12 and the second groove 22 are both open upward. Alternatively, the first groove 12 and the second groove 22 can also be configured to be both open downward (not shown). With such a configuration, during the production process of the connector 100, the production steps of the connector 100 are simplified, and the production efficiency of the connector 100 is improved. In addition, during the assembly process of the connector 100 and the frame 200, the connector 100 can also cooperate with the frame 200 after being turned downward, thereby improving the assembly accuracy of the connector 100 and the frame 200.

[0046] According to some embodiments of the present invention, the first connection part 1 and the second connection part 2 are integrally formed. Thus, the overall connection stability of the first connection part 1 and the second connection part 2 is enhanced, thereby improving the structural strength of the connector 100, which is conducive to the long-term stable use of the connector 100. Moreover, it is also conducive to the production and processing of the connector 100, and the assembly with the frame 200.

[0047] According to some embodiments of the present invention, referring to Figure 2 , there are multiple first connection holes 11, and the multiple first connection holes 11 are arranged at intervals along the first direction; and / or, there are multiple second connection holes 21, and the multiple second connection holes 21 are arranged at intervals along the second direction. In the description of the utility model, the meaning of "multiple" is two or more.

[0048] For example, the arrangement of the first connection hole 11 and the second connection hole 21 includes the following situations: first, only the first connection hole 11 is multiple, and the multiple first connection holes 11 are arranged at intervals along the first direction. Second, only the second connection hole 21 is multiple, and the multiple second connection holes 21 are arranged at intervals along the second direction. Third, Figure 2 As shown, there are a plurality of first connection holes 11 and a plurality of second connection holes 21, the plurality of first connection holes 11 are arranged at intervals along the first direction, and the plurality of second connection holes 21 are arranged at intervals along the second direction. Figure 2 In the example, two first connection holes 11 are provided, and the two first connection holes 11 are spaced apart in the left-right direction; two second connection holes 21 are provided, and the two second connection holes 21 are spaced apart in the front-back direction.

[0049] With such a configuration, when the connector 100 and the frame 200 are assembled, the connection strength between the first connector 1 and the frame 200 is further strengthened, and the connection strength between the second connector 2 and the frame 200 is further strengthened, thereby improving the assembly stability of the connector 100 and the frame 200, and further improving the use stability of the frame assembly 300. However, it is not limited to this. It should be noted that the number and arrangement of the first connection holes 11 and the second connection holes 21 can be specifically set according to actual use to better meet practical applications.

[0050] Optionally, refer to Figure 2 The connector 100 further includes a plurality of first reinforcement members 13 and a plurality of second reinforcement members 23. The plurality of first reinforcement members 13 correspond to the plurality of first connection holes 11, and the first reinforcement members 13 are disposed in the first groove 12, and the first reinforcement members 13 are connected to the inner side wall of the first groove 12. The plurality of second reinforcement members 23 correspond to the plurality of second connection holes 21, and the second reinforcement members 23 are disposed in the second groove 22, and the second reinforcement members 23 are connected to the inner side wall of the second groove 22. The first reinforcement members 13 and the second reinforcement members 23 are respectively formed with threaded holes. For example, in Figure 2 In the example, the first reinforcement 13 and the second reinforcement 23 are respectively annular, the first reinforcement 13 is opposite to the first connecting hole 11 in the front-to-back direction, the first reinforcement 13 is connected to the front side wall of the first groove 12 on one side of the front side wall thereof facing the first groove 12, the second reinforcement 23 is opposite to the second connecting hole 21 in the left-right direction, the second reinforcement 23 is connected to the right side wall of the second groove 22 on one side thereof facing the right side wall thereof.

[0051] In this way, the first reinforcement 13 strengthens the structural strength of the first connection hole 11 from the inner side wall of the first groove 12, and the second reinforcement 23 strengthens the structural strength of the second connection hole 21 from the inner side wall of the second groove 22, thereby improving the structural strength of the connector 100, thereby extending the service life of the connector 100. In addition, when the first fastener 203 passes through the first frame 201 and is inserted into the first connection hole 11, the free end of the first fastener 203 can continue to pass through the first reinforcement 13 and cooperate with the first reinforcement 13, thereby further improving the assembly stability of the first fastener 203 and the first connection part 1. When the second fastener 204 passes through the second frame 202 and is inserted into the second connection hole 21, the free end of the second fastener 204 can continue to pass through the second reinforcement 23 and cooperate with the second reinforcement 23, thereby further improving the assembly stability of the second fastener 204 and the second connection part 2, thereby further improving the assembly stability of the connector 100 and the frame 200, and improving the use stability of the frame assembly 300.

[0052] According to the frame 200 of the second embodiment of the utility model, refer to Figure 3-Figure 6 , including adjacent first frame 201 and second frame 202 , and first fastener 203 and second fastener 204 .

[0053] Specifically, the first frame 201 has at least one first accommodating cavity 2011, and the second frame 202 has at least one second accommodating cavity 2021. The first frame 201 and the second frame 202 are connected by a connecting member 100. The connecting member 100 is a connecting member 100 for the frame 200 according to the first aspect embodiment of the utility model. The first connecting portion 1 of the connecting member 100 is fitted in the first accommodating cavity 2011, and the second connecting portion 2 of the connecting member 100 is fitted in the second accommodating cavity 2021.

[0054] For example, in Figure 3-Figure 6 In the example, the first frame 201 extends in the left-right direction, the second frame 202 extends in the front-back direction, and the right end of the first frame 201 and the front end of the second frame 202 are roughly at a right angle after being spliced. The first accommodating cavity 2011 penetrates the first frame 201 in the left-right direction, the left end of the first connecting portion 1 is inserted into the end of the first accommodating cavity 2011 close to the second frame 202, the second accommodating cavity 2021 penetrates the second frame 202 in the front-back direction, and the rear end of the second connecting portion 2 is inserted into the end of the second accommodating cavity 2021 close to the first frame 201. With such a configuration, the connector 100 strengthens the connection strength between the first frame 201 and the second frame 202, improves the connection stability between the first frame 201 and the second frame 202, thereby improving the use stability of the frame 200, and is also conducive to the rapid assembly of the connector 100 and the frame 200. In addition, the first accommodating cavity 2011 and the second accommodating cavity 2021 can be used to accommodate the first connecting portion 1 and the second connecting portion 2, and the structure is simple and easy to produce, thereby improving the production efficiency of the first frame 201 and the second frame 202, and improving the production efficiency of the frame 200. In addition, the first connecting portion 1 and the first accommodating cavity 2011 are easy to assemble and disassemble, and the second connecting portion 2 and the second accommodating cavity 2021 are easy to assemble and disassemble, thereby improving the assembly efficiency and disassembly efficiency of the frame 200 and the connecting member 100.

[0055] Combination Figure 3-Figure 6 The first fastener 203 penetrates the side wall of the first accommodating cavity 2011 and the first connecting hole 11 of the first connecting part 1 and is connected to the first connecting part 1. The second fastener 204 penetrates the side wall of the second accommodating cavity 2021 and the second connecting hole 21 of the second connecting part 2 and is connected to the second connecting part 2. For example, in Figure 3-Figure 6 In the example, one end of the first fastener 203 passes through the front side wall of the first frame 201 (i.e., the front side wall of the first accommodating cavity 2011) and is threadedly connected to the side wall of the first connecting hole 11, and one end of the second fastener 204 passes through the right side wall of the second frame 202 (i.e., the right side wall of the second accommodating cavity 2021) and is threadedly connected to the side wall of the second connecting hole 21. Both the first connecting hole 11 and the second connecting hole 21 are threaded holes formed with internal threads.

[0056] In this way, the first fastener 203 strengthens the connection strength between the first frame 201 and the first connecting portion 1, and the second fastener 204 strengthens the connection strength between the second frame 202 and the second connecting portion 2, thereby further improving the connection stability between the connecting member 100 and the first frame 201 and the second frame 202, and further improving the use stability of the frame 200, so that the frame 200 can be used normally for a long time. In addition, it is convenient to assemble and disassemble the first fastener 203 with the connecting member 100 and the first frame 201, and it is also convenient to assemble and disassemble the second fastener 203 with the connecting member 100 and the second frame 202, thereby improving the assembly efficiency and disassembly efficiency of the connecting member 100 and the frame 200. For example, the first fastener 203 and the second fastener 204 can be bolts, but are not limited to this.

[0057] According to some embodiments of the present invention, referring to Figure 4 and Figure 6 At least one first through hole 2012 opposite to the first connecting hole 11 is formed on the first frame 201, and the first fastener 203 penetrates the first through hole 2012 and the first connecting hole 11 and is connected to the first connecting portion 1. Figure 4 and Figure 6 In the example, the first perforation 2012 passes through the front side wall of the first frame 201, and the first perforation 2012 and the first connecting hole 11 are opposite to each other in the front-to-back direction. As a result, the smoothness of the first fastener 203 passing through the first frame 201 is improved, and the assembly efficiency of the first fastener 203, the first frame 201 and the first connecting portion 1 is improved, thereby improving the assembly efficiency of the frame assembly 300. In addition, the first perforation 2012 has a positioning effect on the first fastener 203, which is conducive to the rapid assembly of the first fastener 203 and the first frame 201, and the assembly accuracy is high. Moreover, the first perforation 2012 has a simple structure and is easy to produce, thereby improving the production efficiency of the first frame 201. It should be noted that the inner side wall of the first perforation 2012 can be threaded.

[0058] According to other embodiments of the present invention, Figure 4 and Figure 6 At least one second through hole 2022 opposite to the second connecting hole 21 is formed on the second frame 202, and the second fastener 204 penetrates the second through hole 2022 and the second connecting hole 21 and is connected to the second connecting portion 2. Figure 4 and Figure 6In the example, the second through-hole 2022 passes through the right side wall of the second frame 202, and the second through-hole 2022 and the first connecting hole 11 are opposite to each other in the left-right direction. Thus, the smoothness of the second fastener 204 passing through the second frame 202 is improved, and the assembly efficiency of the second fastener 204, the second frame 202 and the second connecting portion 2 is improved. In addition, the second through-hole 2022 has a positioning effect on the second fastener 204, which is conducive to the rapid assembly of the second fastener 204 and the second frame 202, and the assembly accuracy is high. Moreover, the second through-hole 2022 has a simple structure and is easy to produce, thereby improving the production efficiency of the second frame 202. It should be noted that the inner side wall of the second through-hole 2022 can be threaded.
