Description

Technical Field

[0001] The present invention relates to the technical field of network wiring equipment, and in particular to a connection structure, a bracket, a riveted part and a method for surface treatment of the bracket. Background Art

[0002] The bracket is a commonly used cable management rack in network wiring equipment. It is a device used to standardize network wiring. It is generally used in network installation (such as local area network, etc.) and is used in conjunction with switches and installed in cabinets or racks. The bracket is used to organize the cables at the back end of the patch panel, making the back end cable routing more regular, neat and beautiful, and facilitating the maintenance of network equipment and cables.

[0003] The existing foldable bracket structure is that a bracket is connected to each other on both sides of the main board with rivets. There are two common methods for surface treatment of foldable brackets. One is to spray or electroplate the main board and the bracket separately first, and then hinge them together after the spray or electroplating is completed. However, this method of spraying or electroplating in batches leads to low surface processing efficiency of the foldable bracket, and the use of rivets also makes the processing cost of the foldable bracket high; the other is to assemble the main board and the bracket first, and then spray or electroplate the whole. However, the existing foldable bracket cannot be sprayed or electroplated at one time after assembly. It is necessary to rotate and adjust the angle of the bracket to ensure that the visible surface of the entire bracket can be completely sprayed or electroplated. This method also leads to low surface treatment efficiency of the bracket, and inevitably uses rivets, which makes its overall processing cost high.

[0004] Therefore, it is necessary to provide a connection structure, a bracket, a riveted portion and a method for treating the surface of the bracket to solve the above problems. Summary of the invention

[0005] In order to overcome the above-mentioned shortcomings, the purpose of the present invention is to provide a connection structure, a bracket, a riveted portion and a method for bracket surface treatment, which can complete the bracket surface treatment in one go, reduce the production cost of the enterprise, and improve the processing efficiency of the bracket.

[0006] In order to achieve the above purpose, the technical solution adopted by the present invention is: a method for surface treatment of a bracket, the bracket comprising a main board body and a bracket body that are rotatably connected, the main board body and the bracket body are connected by a connecting structure, the main board body and the bracket body are assembled, and the main board body and the bracket body are respectively provided with a main board connecting part and a bracket connecting part;

[0007] The assembled bracket is subjected to surface treatment, wherein the angle between the mainboard body and the bracket body during the surface treatment is a first angle.

[0008] After the treatment is completed, when the bracket body rotates around the mainboard body to a second angle, any area of ​​the working outer surface of the mainboard connecting part and the bracket connecting part is distributed with the surface treatment agent, and the first angle is different from the second angle.

[0009] Furthermore, the surface treatment of the bracket can be spraying, electroplating or baking varnish. Including but not limited to the above three methods of spraying, electroplating or baking varnish, as long as the surface of the bracket is distributed with a surface treatment agent. When spraying, powder spraying can be used, and when electroplating, the bracket can be placed in a plating tank filled with a plating solution.

[0010] A connection structure for realizing a rotatable connection between a first component and a second component, characterized in that: the first component is provided with a first connection portion,

[0011] The second component is provided with a second connecting portion,

[0012] The circles on which the moving trajectories of the points on the edge of the first connecting portion lie are the same circle, which is the first circle.

[0013] The circles on which the moving trajectories of the points on the edge of the second connecting portion lie are the same circle, which is the second circle.

[0014] The first circle and the second circle are arranged concentrically.

[0015] The present application maintains the moving trajectory of each point on the edge of the first connecting part on the same circle - the edge line of the first circle; and at the same time maintains the moving trajectory of each point on the edge of the second connecting part on the same circle - the edge line of the second circle, thereby ensuring that when the first component and the second component rotate, the first connecting part and the second connecting part will never block each other. Therefore, the first component and the second component can be sprayed, electroplated or painted after assembly, and the effect of spraying, electroplating or painting without dead angles can be achieved.

[0016] Furthermore, the mainboard connection part and the bracket connection part are arranged concentrically, and the outer edges of the mainboard connection part and the bracket connection part are both semicircular. The two concentrically arranged semicircles enable the bracket body to rotate at any angle with the riveted part as the center, and all visible surfaces of the bracket body and the mainboard body are distributed with the surface treatment agent.

[0017] A bracket, wherein the first component is a mainboard body, and the second component is a bracket body; the first connecting portion is a mainboard connecting portion, and the second connecting portion is a bracket connecting portion; the mainboard body and the bracket body are rotatably connected. The mainboard body and the bracket body are rotatably connected to achieve foldability of the mainboard body and the bracket body, so that when the bracket is not in use, the bracket body is folded to the side of the mainboard body, effectively reducing the occupied space by nearly 50% during packaging, thereby reducing the packaging cost and transportation cost of the enterprise.

[0018] Furthermore, the bracket connection portion is fixedly connected to the side of the bracket body through the support portion, the horizontal plane on the bracket connection portion is connected to the support portion, and the plane where the bracket connection portion is located is perpendicular to the plane where the bracket body is located.

[0019] Furthermore, the support portion is provided with a snap-in protrusion protruding from its surface in the direction toward the mainboard body, and the mainboard body is provided with a snap-in slot for the snap-in protrusion to snap into when the bracket body abuts against the side of the mainboard body. By providing corresponding snap-in protrusions and snap-in slots, the bracket mainboard is not easy to be recovered when the bracket is in the working state, thereby ensuring the stability of the bracket hanging the cable in the working state. It should be noted that the snap-in protrusion and the snap-in slot are not limited to being provided on the support portion and the mainboard body respectively. When the snap-in slot is provided on the mainboard body, the snap-in protrusion provided on the support portion can also achieve the same effect.

[0020] Furthermore, the mainboard connecting parts are located on the lower surfaces of both ends of the mainboard body in the length direction and extend toward the outside of the mainboard body.

[0021] Furthermore, one of the two surfaces of the mainboard body in contact with the bracket body is provided with at least one positioning protrusion, and the other surface is provided with at least one positioning groove for the positioning protrusion to be inserted into.

[0022] Furthermore, the bracket body also includes a mounting portion, a hook is provided on one end of the mounting portion away from the supporting portion, and a plurality of buckle structures for cable tie buckles to be installed are provided on the mainboard body along its length direction. The hook is used to mount the entire bracket on a matching wiring rack to organize network cables.

[0023] The buckle structure includes a network cable slot and a T-shaped hook. The T-shaped hook facilitates the clamping of the cable buckle and improves the convenience of use. When the cable buckle is not in use, the network cable slot can also store the network cable.

[0024] It should be noted that there is no restriction on the size and arrangement of the snap-in structure, as long as the quantity and size requirements of the network cables can be met.

[0025] Furthermore, at least one groove is provided on the mainboard body along its length direction on a side away from the riveting part, and the depth of the groove is greater than the thickness of the mainboard body. The groove can enhance the overall strength of the bracket and improve the service life of the bracket.

[0026] Furthermore, the diameter of the mainboard connection part is equal to the diameter of the bracket connection part. The bracket body is connected to the mainboard bracket through the bracket connection structure. Only when the diameters of the mainboard connection part and the bracket connection part are the same, it can be ensured that all visible surfaces of the mainboard body and the bracket body can be processed at one time, so that all visible surfaces are distributed with the surface treatment agent.

[0027] A riveted part is used to flexibly connect the main board body and the bracket body. The riveted part is formed on the main board body or the bracket body by stretching and passes through the center of the bracket connection part or the main board connection part. The existing riveting parts are all rivets. After the main board body and the bracket body are connected by rivets, the whole body is sprayed, electroplated or painted.

[0028] During spraying and painting, the spraying is powder spraying. When rivets are used for locking, there is a gap between the contact surfaces of the nut and the mainboard body. The powder cannot completely enter from the gap to completely spray the above-mentioned contact surface. In addition, some powder will accumulate around the nut on the mainboard body, which leads to uneven spraying and affects the surface appearance of the bracket.

[0029] During electroplating, the rivet is locked so that there is a gap between the contact surface of the nut and the mainboard body. Since the rivet is made of iron, electroplating liquid will remain on the rivet after the electroplating is completed, causing the rivet to rust, thereby affecting the overall appearance of the bracket.

[0030] The riveted part in the present application is integrally formed with the mainboard body or the bracket body. In addition to eliminating the need to use additional rivets during the assembly of the bracket, effectively reducing the company's production costs, it can also ensure the overall appearance of the bracket during subsequent spraying, electroplating or painting, and will not rust.

[0031] Furthermore, the rivet portion protrudes from the surface of the mainboard body or the bracket body. When the mainboard body and the bracket body are assembled, the rivet portion passes through the corresponding bracket connection portion or mainboard connection portion and rivets, so that the mainboard body and the bracket body are riveted together. During the assembly process, no additional rivets are required to assemble the mainboard body and the bracket body, thereby effectively reducing the production cost of the enterprise.

[0032] Furthermore, the tops of both ends of the mainboard body in the length direction are respectively provided with a slot for the bracket body to rotate and snap in. When the bracket body is placed horizontally, the support part can play a certain supporting role on the support body, so that the placement of the bracket body is more stable when in use.

[0033] Beneficial effects of the present invention:

[0034] 1. In the present application, the mainboard body and the bracket body are assembled before surface treatment, and the outer edges of the mainboard connection part and the bracket connection part are semicircular structures of the same diameter, so that the assembled bracket can be surface treated once to achieve that all visible surfaces of the assembled bracket are evenly treated with the surface treatment agent, effectively improving the efficiency of the bracket surface treatment and reducing the company's production costs.

[0035] 2. In the present application, when the mainboard connection part and the bracket connection part are respectively installed on the mainboard body and the bracket body, they are connected by a connecting axis passing through the centers of the two circles to realize a foldable connection between the mainboard body and the bracket body. At the same time, when the mainboard body and the bracket body are subsequently sprayed, electroplated or painted as a whole, the semicircular structure of the mainboard connection part and the bracket connection part can also ensure that the surface treatment agent is completely distributed on all visible surfaces during the rotation of the mainboard connection part and the bracket connection part after one surface treatment, thereby effectively improving the processing efficiency of the bracket.

[0036] 3. In the present application, an integrally formed rivet portion is provided on the surface of the main board body or the bracket body. When connecting the main board body and the bracket body, there is no need to use additional screws to connect the main board connection portion and the bracket connection portion. The rivet portion can be passed through the main board connection portion and the bracket connection portion and then pressed together, so that the main board connection portion and the bracket connection portion can be riveted together, thereby effectively reducing the production cost of the enterprise.

[0037] 4. In the present application, the mainboard connection part, the bracket connection part, the mainboard body, the bracket body, the riveted part, the positioning protrusions and the positioning grooves cooperate with each other. When the bracket body is rotated to the surface treatment angle, the positioning protrusions can be inserted into the corresponding positioning grooves to avoid the relative rotation of the bracket body and the mainboard body during the surface treatment process, which affects the effect of the surface treatment. The arrangement of the mainboard connection part and the bracket connection part ensures that the visible surfaces of the assembled mainboard body and the bracket body in all states can be processed at one time, effectively improving the processing efficiency of the bracket.

DETAILED DESCRIPTION

[0051] The preferred embodiments of the present invention are described in detail below in conjunction with the accompanying drawings so that the advantages and features of the present invention can be more easily understood by those skilled in the art, thereby making a clearer and more definite definition of the protection scope of the present invention.

[0052] See attached Figures 1 to 12 The present invention provides a method for surface treatment of a bracket, wherein the bracket includes a mainboard body 1 and a bracket body 2 that are rotatably connected, and the mainboard body 1 and the bracket body 2 are assembled, and a mainboard connecting portion 12 and a bracket connecting portion 23 are respectively provided on the mainboard body 1 and the bracket body 2; here, the assembly of the mainboard body 1 and the bracket body 2 can be pre-rotated or fully installed.

[0053] The assembled bracket is subjected to surface treatment, and the angle between the mainboard body 1 and the bracket body 2 during the surface treatment is a first angle.

[0054] After the treatment is completed, when the bracket body rotates around the mainboard body to a second angle, any area of ​​the working outer surface of the mainboard connecting part 12 and the bracket connecting part 23 is distributed with the surface treatment agent, and the first angle is different from the second angle.

[0055] Before the surface treatment, the angle between the mainboard body 1 and the bracket body 2 is the first angle, and the first angle can be any angle. In the prior art, since the working outer surfaces of the mainboard body 1 and the bracket body 2 will block each other, it is impossible to achieve that all exposed positions at any angle in all areas of the outer surfaces of the mainboard body 1 and the bracket body 2 after assembly are evenly treated with the surface treatment agent through one surface treatment, that is, all visible surfaces of the bracket at any angle of rotation of the bracket body 2 can be surface treated. Therefore, it is usually necessary to separately treat the surfaces of the mainboard body 1 and the bracket body 2 before assembling them, but it is inevitable that certain scratches will be caused on the surfaces of the two during the assembly process. In the present application, the mainboard body 1 and the bracket body 2 are assembled first, and then the overall surface treatment is performed after the assembly is completed. In addition, the semicircular structure of the edge of the mainboard connection part 12 and the bracket connection part 23 in the present application allows the assembled bracket to be surface treated once so that all visible surfaces of the assembled bracket are evenly treated with the surface treatment agent, which effectively improves the efficiency of the bracket surface treatment, reduces the company's production costs, and can also avoid surface damage to the mainboard body 1 and the bracket body 2.

[0056] It should be noted that the "working outer surface" here refers to any side surface of the wire support frame when it is in working state. The area where the mainboard connection part 12 and the bracket connection part 23 are blocked or covered by each other does not belong to the "working outer surface". Figure 6 The shaded part in the figure is the “working outer surface”.

[0057] The surface treatment of the bracket can be spraying, electroplating or baking varnish. If the surface treatment method of spraying is adopted, the surface treatment agent is a coating liquid or powder; if the surface treatment method of electroplating is adopted, the surface treatment agent is an electroplating liquid. Including but not limited to the above three methods of spraying, electroplating or baking varnish, as long as the surface treatment agent can be distributed on the surface of the bracket. When spraying, powder spraying can be used, and when electroplating, the bracket can be placed in an electroplating tank filled with electroplating liquid. It should be noted that this application is not limited to only the three types of spraying, electroplating and baking varnish, but also applicable to other surface treatments such as sandblasting and painting.

[0058] See attached Figures 1 to 9 , a connection structure for realizing a rotatable connection between a first component and a second component, characterized in that: the first component is provided with a first connection portion,

[0059] The second component is provided with a second connecting portion,

[0060] The circles on which the moving trajectories of the points on the edge of the first connecting portion lie are the same circle, which is the first circle.

[0061] The circles on which the moving trajectories of the points on the edge of the second connecting portion lie are the same circle, which is the second circle.

[0062] The first circle and the second circle are arranged concentrically.

[0063] Therefore, the present application maintains the moving trajectory of each point on the edge of the first connecting part on the same circle - the edge line of the first circle; and at the same time, maintains the moving trajectory of each point on the edge of the second connecting part on the same circle - the edge line of the second circle, thereby ensuring that when the first component and the second component rotate, the first connecting part and the second connecting part will never block each other. Therefore, the first component and the second component can be sprayed or electroplated after assembly and the effect of spraying or electroplating without dead angles can be achieved.

[0064] It is not necessary to avoid the blind area of ​​spraying or electroplating caused by the mutual shielding between the first component and the second component. Fig.10 For example, the circle where the rotation trajectory of the first point A on the edge of the first connecting part when the first connecting part rotates is circle a, and the circle where the rotation trajectory of the first point B on the edge of the first connecting part when the first connecting part rotates is circle b. Since the diameters of circles a and b are different, when the first point A is at different positions, the overlapping area between the first connecting part and the second connecting part is different. Therefore, there are always areas on the first component and the second component that cannot be completely sprayed or electroplated.

[0065] The mainboard connection part 12 and the bracket connection part 23 are arranged concentrically, and the outer edges of the mainboard connection part 12 and the bracket connection part 23 are both semicircular. The two concentrically arranged semicircles enable the bracket body 2 and the mainboard body 1 to have surface treatment agents distributed on all visible surfaces when the bracket body 2 is rotated at any angle with the riveted part 11 as the center.

[0066] During the subsequent overall surface treatment of the mainboard body 1 and the bracket body 2, it can be ensured that one surface treatment can make all visible surfaces of the bracket during the rotation of the mainboard connection part 12 and the bracket connection part 23 completely distributed with the surface treatment agent, thereby effectively improving the processing efficiency of the bracket. There is no need to adjust the angle of the bracket body 2 multiple times to repeat the surface treatment, and completing it once can also make the surface treatment of the bracket more uniform, thereby ensuring its processing quality.

[0067] It should be noted that the outer edges of the first connection part and the second connection part are not limited to being only semicircular, but can also be a complete circle, as long as the first connection part and the second connection part can always cover each other during the rotation around the same center of the circle, so that in the subsequent surface treatment process, there will be no areas on the first component and the second component that cannot be completely surface treated.

[0068] See attached Figures 1 to 3 A bracket, wherein the first component is a mainboard body 1, and the second component is a bracket body 2; the first connecting portion is a mainboard connecting portion 12, and the second connecting portion is a bracket connecting portion 23; the mainboard body 1 and the bracket body 2 are rotatably connected. The mainboard body 1 and the bracket body 2 are rotatably connected to achieve the foldability of the mainboard body 1 and the bracket body 2, so that when the bracket is not in use, the bracket body 2 is folded on the side of the mainboard body 1, effectively reducing the occupied space by nearly 50% during packaging, thereby reducing the packaging cost and transportation cost of the enterprise.

[0069] See attached Figures 6 to 7 The bracket connection part 23 is fixedly connected to the side of the bracket body 2 through the support part 22, the horizontal surface on the connection part is connected to the support part 22, and the plane where the bracket connection part 23 is located is perpendicular to the plane where the bracket body 2 is located. It can be seen from the accompanying drawings that the support part 22 and the bracket connection part 23 are divided into two parts by the diameter of the bracket connection part 23.

[0070] In some embodiments, see Appendix Figure 6 The support portion 22 includes a hinge portion 8 and a receiving portion 9. The bracket connecting portion 23 is connected to the bracket body 2 through the hinge portion 8. The receiving portion 9 is arranged on the side of the hinge portion 8 and the bottom surface is connected to the bracket connecting portion 23. The plane where the support portion 22 is located is perpendicular to the plane where the bracket body 2 is located. When the bracket body 2 is rotated to the side surface thereof abutting against the mainboard body 1, one end of the receiving portion 9 is clamped in the card slot 14, so that when the bracket is working, it plays a certain supporting role on the mainboard body 1, making the overall use of the bracket more stable.

[0071] It should be noted that the size of the receiving portion 9 is not limited, as long as it is ensured that the overall primary surface treatment of the visible surface of the bracket will not be affected when the bracket body 2 is subsequently rotated, positioned, sprayed, electroplated, or painted.

[0072] In other embodiments, the support portion 22 includes a hinge portion 8, the bracket connection portion 23 is connected to the bracket body 2 through the hinge portion 8, the plane where the hinge portion 8 is located is perpendicular to the plane where the bracket body 2 is located, and the hinge portion 8 is a square with a length equal to the diameter of the bracket connection portion 23 and a height greater than or equal to the radius of the bracket connection portion 23. In this embodiment, during the subsequent bracket surface treatment, any angle within the rotation range of the bracket body 2 will not interfere with the surface treatment effect. In this case, the positioning protrusion 5 and the positioning groove 4 can also be arbitrarily set in position and quantity around the center of the bracket connection portion 23 or the mainboard connection portion 12.

[0073] In some other embodiments, see the attached Figure 7 and 11 The support portion 22 includes a hinge portion 8, and the hinge portion 8 has no receiving portion 9 on its side. Figure 7 With attached Fig.11 The shape of the hinged portion 8 is different. Fig.11 It is not a complete rectangle. When the hinged portion 8 is arranged to be attached Figure 7 When the shape is in the figure, the angle at which the bracket body 2 can rotate without affecting the complete surface treatment of the visible surface of the bracket is θ as shown in the figure, that is, setting the hinge part 8 of different shapes can enable the bracket body 2 to obtain different rotation ranges.

[0074] It should be noted that, see Appendix Figure 7 The angle θ of rotation of the bracket body 2 refers to the rivet portion 11 as the vertex, the line connecting the rivet portion 11 and the hook 24 on the bracket body 2 is one side, and the ray connecting the rivet portion 11 where the bottom surface of the mainboard body 1 is located is the other side.

[0075] See attached Fig.12 The support portion 22 is provided with a snap-in protrusion 10 protruding from its surface in the direction toward the main board body 1, and the main board body 1 is provided with a snap-in slot 15 for the snap-in protrusion 10 to snap into when the bracket body 2 abuts against the side of the main board body 1. By providing corresponding snap-in protrusions 10 and snap-in slots 15, when the bracket main board 2 is in the working state, it is not easy to recycle, thereby ensuring the stability of the bracket hanging cables in the working state. It should be noted that the snap-in protrusion 10 and the snap-in slot 15 are not limited to being provided on the support portion 22 and the main board body 1 respectively. When the snap-in slot 15 is provided on the main board body 1, the snap-in protrusion 10 provided on the support portion 22 can also achieve the same effect.

[0076] The motherboard connection part 12 is located on the lower surface of both ends of the motherboard body 1 in the length direction, and extends toward the outside of the motherboard body 1. It is convenient to hinge the motherboard connection part 12 with the bracket connection part 23, so that the bracket body 2 can rotate around the hinge point to abut against the lower surface or side of the motherboard body 1. It should be noted that the motherboard connection part 12 is not limited to being set on the lower surface of the end of the motherboard body 1. When it is set on the side of the motherboard body 1, the effect of this application can also be achieved. See the attached Figure 3 In the present application, the lower surface of the mainboard body 1 is indicated by an arrow in the figure.

[0077] The two surfaces of the mainboard body 1 and the bracket body 2 are in contact, one of which is provided with at least one positioning protrusion 5, and the other surface is provided with at least one positioning groove 4 for the positioning protrusion 5 to be inserted into. By providing the positioning protrusion 5 and the positioning groove 4, the rotation of the bracket body 2 on the mainboard body 1 is positioned. The positioning protrusion 5 and the positioning groove 4 are both arranged around the center of the circle, so that the positioning of the bracket body 2 is more stable when it is rotated to the spraying or electroplating position or to the bracket use state position. It should be noted that the bracket use state here refers to the bracket body 2 rotating to its side against the side of the mainboard body 1.

[0078] See attached Figures 4 to 5 In some embodiments, four positioning grooves 13 are provided on the mainboard body 1, and two positioning protrusions 5 are provided on the bracket body 2. When the bracket body 2 is rotated to abut against the side of the mainboard body 1, one of the two positioning protrusions 5 is used to position the bracket body 2 to ensure the stability of the entire bracket during use. The other protrusion is used for subsequent surface treatment when the bracket body 2 is rotated to a specified surface treatment position for positioning, thereby avoiding position deviation of the bracket body 2 during the surface treatment process, thereby affecting the overall effect of the surface treatment.

[0079] The two positioning protrusions 5 are arranged in an array around the center of the bracket connecting part 23, and the two positioning protrusions 5 are specifically located on the diameter of the bracket connecting part 23. The four positioning grooves 13 on the mainboard body 1 are arranged in an array around the center of the mainboard connecting part 12, wherein two positioning grooves 13 are arranged on the diameter of the mainboard connecting part 12, and the other two positioning grooves 13 are arranged on the symmetry axis of the mainboard connecting part 12. During surface treatment, the bracket body 2 is rotated until the two positioning protrusions 5 thereon are clamped in the horizontally arranged positioning grooves 4 on the mainboard body 1. At this time, the straight line on which the length direction of the bracket body 2 is located is parallel to the straight line on which the length direction of the mainboard body 1 is located, and the best effect can be achieved during subsequent surface treatment.

[0080] In other embodiments, the number of the positioning protrusions 5 on the bracket body 2 can be set to one, and the position of the positioning grooves 4 on the mainboard body 1 can be set to two correspondingly, so that the position of the bracket body 2 during surface treatment and the position during use can be positioned. Of course, the one positioning protrusion 5 here can also be set on the mainboard body 1, and then two positioning grooves 4 are correspondingly set on the bracket body 2.

[0081] It should be noted that the specific positions of the positioning protrusions 5 and the positioning grooves 13 are not limited, as long as the settings of the positioning protrusions 5 and the positioning grooves 13 meet the requirements of the overall surface treatment of the bracket, and the position of the positioning protrusions 5 is set shallowly, and no interference will occur during the rotation of the bracket body 2.

[0082] See attached Figure 2 and 8 The bracket body 2 further comprises a mounting portion 21, and a hook 24 is disposed at one end of the mounting portion 21 away from the supporting portion 22. The hooks 24 can be disposed at two ends of the bottom of the mounting portion 21 facing each other, or at the bottom of the mounting portion 21 in the same direction. The arrangement of the hooks 24 can be changed according to the structure of the distribution frame assembled with the bracket, so that the bracket can be mounted on the distribution frame through the hooks 24.

[0083] The mainboard body 1 is provided with a plurality of buckle structures 6 for installing cable ties along its length. The buckle structure 6 includes a network cable slot and a T-shaped hook. The T-shaped hook facilitates the clamping of the cable ties, improving the convenience of use. When the cable ties are not used, the network cable slot can also store network cables. The network cable slot is an E-shaped slot. Of course, the shape of the network cable slot here is not limited to an E-shaped slot, as long as it can meet the insertion and storage requirements of the network cable.

[0084] It should be noted that the size and arrangement of the buckle structure 6 are not limited as long as they can meet the quantity and size requirements of the network cables.

[0085] At least one groove 13 is provided on the side of the mainboard body 1 away from the riveting portion along its length direction, and the depth of the groove 13 is greater than the thickness of the mainboard body 1. The groove 13 can enhance the overall strength of the bracket and improve the service life of the bracket.

[0086] The diameter of the mainboard connection part 12 is equal to the diameter of the bracket connection part 23. The bracket body 1 is connected to the mainboard bracket 1 through the connection structure. Only when the diameters of the mainboard connection part 12 and the bracket connection part 23 are the same, it can be ensured that all visible surfaces of the mainboard body 1 and the bracket body 2 can be processed at one time, so that all visible surfaces are distributed with the surface treatment agent.

[0087] See attached Figures 2 to 3 , a slot 14 for the bracket body 2 to be rotated and inserted is respectively provided at the top of both ends in the length direction of the mainboard body 1. In some embodiments, the support portion 22 on the bracket body 2 is perpendicular to the mounting portion 21. When the bracket is in use, the bracket body 2 is rotated to abut against the mainboard body 1 at its side. The support portion 22 is located behind the mainboard body 1. When the bracket body 2 is placed horizontally, the support portion 22 can play a certain supporting role on the support body, so that the placement of the bracket body 2 is more stable when in use.

[0088] A riveted part is used to flexibly connect the main board body 1 and the bracket body 2. The riveted part 11 is integrally formed on the main board body 1 or the bracket body 2 by stretching, and passes through the center of the bracket connecting part 23 or the main board connecting part 12. The existing riveted parts 11 are all rivets. After the main board body 1 and the bracket body 2 are connected by rivets, the whole body is sprayed, electroplated or painted.

[0089] It should be noted that the shape of the integrally formed riveted portion includes but is not limited to a cylindrical shape or other shapes, as long as the mainboard body 1 and the bracket body 2 can be finally riveted together.

[0090] During spraying and painting, the spraying is powder spraying. When rivets are used for locking, there is a gap between the contact surfaces of the nut and the mainboard body 1. The powder cannot completely enter the above-mentioned contact surface from the gap to completely spray the part. In addition, some of the powder will accumulate around the nut on the mainboard body, which leads to uneven spraying and affects the surface aesthetics of the bracket.

[0091] During electroplating, the rivet is locked so that there is a gap between the contact surface of the nut and the main board body 1. During the electroplating process, since the rivet is made of iron, electroplating liquid will remain on the rivet after the electroplating is completed, causing the rivet to rust, thereby affecting the overall appearance of the bracket.

[0092] The riveted portion 11 in the present application is integrally formed with the mainboard body 1 or the bracket body 2. In addition to eliminating the need for additional rivets during the assembly of the bracket, which effectively reduces the company's production costs, it can also ensure the overall appearance of the bracket during subsequent spraying, electroplating or painting, and will not rust.

[0093] The rivet portion 11 is protruding from the surface of the mainboard body 1 or the bracket body 2. When the mainboard body 1 and the bracket body 2 are assembled, the rivet portion 11 passes through the corresponding bracket connection portion 23 or the mainboard connection portion 12 and rivets, so that the mainboard body 1 and the bracket body 2 are riveted together. During the assembly process, no additional rivets are required to connect the mainboard body 1 and the bracket body 2, thereby effectively reducing the production cost of the enterprise.

[0094] In some embodiments, the rivet portion 11 is integrally formed on the mainboard body 1 and passes through the center of the mainboard connecting portion 12 connected to the mainboard body 1. When the mainboard body 1 is connected to the bracket body 2, the rivet portion 11 on the mainboard body 1 also passes through the center of the bracket connecting portion 23, and then the mainboard body 1 and the bracket body 2 are riveted together by riveting. During the assembly process, no additional rivets are required to assemble the mainboard body 1 and the bracket body 2, thereby effectively reducing the production cost of the enterprise.

[0095] It should be noted that the riveted portion 11 can also be integrally formed on the bracket body 2 and pass through the center of the circle on the bracket connecting portion 23. When connecting the mainboard body 1, as long as the riveted portion 11 passes through the center of the mainboard connecting portion 12 on the mainboard body 1, it is not limited to be set on the mainboard body 1.

[0096] In some embodiments, after the bracket is assembled, a clamp is used to vertically hoist the bracket. This hoisting method can reduce the space occupied during the surface treatment of the bracket, so that multiple brackets can be surface treated at the same time, thereby effectively improving the processing efficiency of the bracket; after the hoisting is completed, the bracket body 2 at both ends of the bracket is rotated so that the positioning protrusions 5 on the bracket are inserted into the corresponding positioning grooves 4, thereby positioning the position of the bracket body 2 during surface treatment; after the positioning is completed, the hoisted bracket is placed in a spraying device or an electroplating tank for spraying or electroplating.

[0097] Among them, when adjusting the position of the bracket body 2, the rotation process takes the riveted portion 11 as the center of the circle. The positioning protrusion 5 and the positioning groove 4 are set to ensure that when the bracket is subsequently surface treated, the position of the bracket body 2 relative to the mainboard body 1 will not change, and to ensure that the bracket body 2 will not block the visible surface on the mainboard body 1, thereby ensuring that the surface treatment of the bracket is completed in one time, thereby ensuring the bracket processing efficiency.

[0098] It should be noted that the positions and numbers of the positioning protrusions 5 and the positioning grooves 4 on the bracket are not limited, as long as the bracket body 2 can be positioned and the positioning will not affect the effect of spraying or electroplating.

[0099] The mainboard body 1 is provided with four positioning grooves 13, and the bracket body 2 is provided with two positioning protrusions 5. When the bracket body 2 is rotated to abut against the side of the mainboard body 1, one of the two positioning protrusions 5 positions the bracket body 2. During the surface treatment process, the bracket is always in a folded state. It should be noted that in the working state, the bracket body 2 is perpendicular to the mainboard body 1, and the folded state is a relative position relationship other than the perpendicular relationship.

[0100] The clamp used in this embodiment is a hook. When hoisting, the hook passes through the E-shaped groove on the buckle structure. The E-shaped groove that the hook passes through is the E-shaped groove close to the top of the bracket body, and the length of the line connecting the contact points on the hook and the E-shaped groove is about 0.8 mm. That is, the contact surface between the hook and the E-shaped groove is small enough, and the shielding effect generated during the spraying or electroplating process can be ignored, and will not affect the spraying or electroplating effect of the bracket as a whole.

[0101] This method can achieve the best spraying, electroplating or baking varnish effect for the bracket. It should be noted that the structure of the clamp for clamping the bracket in this method is not the content to be protected by this application, as long as it can meet the requirement of not affecting the subsequent spraying and electroplating during the process of hoisting the bracket, therefore, its specific structure will not be described in detail here.

[0102] The above implementation modes are only for illustrating the technical concept and features of the present invention, and their purpose is to enable people familiar with this technology to understand the content of the present invention and implement it, and they cannot be used to limit the protection scope of the present invention. Any equivalent changes or modifications made according to the spirit of the present invention should be included in the protection scope of the present invention.
