[0040] Reference to "embodiments" herein means that a particular feature, structure, or characteristic described in conjunction with the embodiments may be included in at least one embodiment of the present application. The appearance of the phrase in various locations in the specification does not necessarily refer to the same embodiment, nor is it an independent or alternative embodiment that is mutually exclusive with other embodiments. It is explicitly and implicitly understood by those skilled in the art that the embodiments described herein may be combined with other embodiments.

[0044] In the description of the embodiments of the present application, unless otherwise clearly specified and limited, technical terms such as "installed", "connected", "connected", "fixed" and the like should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium, and it can be the internal connection of two elements or the interaction relationship between two elements. For those of ordinary skill in the art, the specific meanings of the above terms in the embodiments of the present application can be understood according to the specific circumstances.

[0045] At present, in order to facilitate centralized management and storage of network security machines, multiple network security machines are usually placed in the same cabinet at intervals. Figure 1 As shown, the cabinet includes four cabinet columns arranged symmetrically in pairs. When the network security machine needs to be placed on the cabinet, it is usually necessary to install hanging ears and a pallet on the cabinet; wherein the hanging ears are parts installed on both sides of the front and rear panels of the network security machine or server, and are provided with openings, and the network security machine or server can be fixed on the cabinet through the hanging ears. By installing the hanging ears and the pallet on the cabinet, placing the network security machine on the pallet, and fixing the network security machine to the hanging ears, the network security machine can be successfully placed on the cabinet.

[0046] like Figure 1 As shown, the steel plate is processed into an L-shaped pallet by a bending machine, and the two ends of the L-shaped pallet are bent into hanging ears. Through the openings on the hanging ears, the two L-shaped pallets can be symmetrically fixed on the columns of the cabinet, thereby achieving the purpose of placing the network security machine on the L-shaped pallet.

[0047] like Figure 2 As shown, by symmetrically installing guide rails on the cabinet, and then fixing the network security machine to the guide rails on both sides, the purpose of fixing the network security machine on the cabinet is achieved.

[0048] However, since the size of the L-shaped pallet is fixed, it cannot be adapted to cabinet columns with different spacings, resulting in the L-shaped pallet being unable to be installed on cabinets of different sizes, and thus the L-shaped pallet being unable to be adapted to network security machines of different depths. In addition, since network security machines are different from servers, the sides of the network security machine chassis usually do not have openings or I-shaped nails for connecting and fixing to the guide rails. Therefore, when fixing the network security machine to the guide rails on both sides, additional openings are required in the chassis of the network security machine. In addition, the guide rails have a complex structure, are heavy and expensive, and choosing to install and fix the network security machine on the guide rails will increase the cost of using the network security machine and reduce economic benefits.

[0049] Based on this, an embodiment of the present application provides a bracket assembly, which includes two brackets arranged at intervals, each bracket including a support plate, a fixed plate and a pull-out plate. A support flat plate is formed by bending one side edge of the support plate inward, and the network security machine can be directly placed on the support flat plate so that the support flat plate can carry the network security machine. Compared with using a guide rail to install and fix the network security machine, there is no need to open holes in the network security machine, thereby reducing the use cost of the network security machine; by sliding the pull-out plate in the accommodating cavity formed by the fixed connection between the support plate and the fixed plate, the length of each bracket can be changed by sliding the pull-out plate in opposite directions, so that the bracket assembly can adapt to cabinet columns with different spacings, so that the bracket assembly can be installed on cabinets of different sizes, and then can adapt to and carry network security machines of different depths.

[0050] See also Figure 3-Figure 5, Figure 3 A three-dimensional diagram showing a bracket assembly provided in an embodiment of the present application installed on a cabinet is shown. Figure 4 An exploded schematic diagram of a bracket provided in an embodiment of the present application is shown. Figure 5 The cross-sectional structure diagram of the bracket provided in the embodiment of the present application is shown, wherein: Figure 3 The dotted arrow indicates outward, and the straight arrow indicates inward. As shown in the figure, the bracket assembly 10 is used to be installed in the cabinet 20 to place the network security device 30. The bracket assembly 10 includes two brackets 100 arranged at intervals, and each bracket 100 includes a support plate 110, a fixing plate 120 and a pull-out plate 130.

[0051] The edge of one end of the support plate 110 is bent outward to form a front end ear 111, and the edge of one side is bent inward to form a support plate 112. The front end ear 111 is used to be fixedly connected to the front column 21 of the cabinet, and the support plate 112 is used to support the network security device 30. The fixing plate 120 is fixedly arranged on the side of the support plate 110 away from the support plate 112.

[0052] At least one of the support plate 110 and the fixing plate 120 is recessed in a direction away from the other so that a receiving cavity 140 is formed between the support plate 110 and the fixing plate 120, and a first fixing member 113 is provided on a side of at least one of the support plate 110 and the fixing plate 120 facing the other, and the first fixing member 113 is located in the receiving cavity 140.

[0053] The drawer plate 130 includes a drawer main board 131 and a rear end hanging ear 132. The rear end hanging ear 132 is formed by bending an end edge of the drawer main board 131 outward. The rear end hanging ear 132 is used to be fixedly connected to the rear column 22 of the cabinet. The drawer main board 131 is provided with a first slide hole 1311 along its length. The first fixing member 113 is inserted into the first slide hole 1311, so that the drawer main board 131 is slidably connected to the support plate 110 or the fixing plate 120 to be telescoped in the accommodating cavity 140.

[0054] The network security device 30 may be a network security machine or a server with security functions. The bracket assembly 10 is processed as a whole by sheet metal processing, which not only has high structural strength but also has simple processing technology.

[0055] Specifically, Figure 3 and Figure 4As shown, the support plate 110 is an L-shaped structure as a whole. Among them, the front end hanging ear 111 is bent in the direction away from each other of the two brackets 100, and the front end hanging ear 111 can be fixedly connected to the cabinet front column 21 by opening a through hole on the front end hanging ear 111 and fixing the through hole with the mounting hole on the cabinet front column 21 by screws and nuts. The support flat plate 112 is bent in the direction of the two brackets 100 facing each other. When the network security device 30 is placed on the cabinet 20, the support flat plates 112 of the two brackets 100 are used to carry the network security device 30.

[0056] Optionally, see Figure 6 , Figure 6 The structural schematic diagram of the support plate provided by the embodiment of the present application is shown. As shown in the figure, the edge of one side of the support plate 112, that is, the edge of the side where the longer side of the support plate 112 is located, can be bent in the opposite direction toward the bottom of the support plate 112 to form a first reinforcing plate 1121, and the top of the first reinforcing plate 1121 is fitted and fixedly connected to the bottom of the support plate 112 to increase the structural strength of the support plate 112. Specifically, the first reinforcing plate 1121 can be formed at the bottom of the support plate 112 by a dead edge pressing process to further enhance the overall structural strength and stability of the support plate 112.

[0057] Combination Figure 4 and Figure 6 The fixing strips 121 on both sides of the fixing plate 120 can be fixedly connected to the support plate 110 by riveting, welding, bonding, screw fastening or clamping, so that the fixing plate 120 is fixed to the side of the support plate 110 away from the support flat plate 112. Optionally, the support plate 110 can be recessed in a direction away from the fixing plate 120, so that after the support plate 110 is fixedly connected to the fixing plate 120, the support plate 110 can form a receiving cavity 140 together with the fixing plate 120; Figure 5 As shown, the fixing plate 120 is recessed in a direction away from the supporting plate 110 so that the cross section of the fixing plate 120 is in a "J" shape, so that after the fixing plate 120 is fixedly connected to the supporting plate 110, the fixing plate 120 can form a receiving cavity 140 together with the supporting plate 110.

[0058] Alternatively, if Figure 4 As shown, a through hole array 114 can be provided at one end of the support plate 110 that is bent to form the front end hanging ear 111, and another through hole array 122 can be provided at a position of the fixing plate 120 corresponding to the through hole array 114 of the support plate 110. Specifically, the density and area size of the through hole arrays (114, 122) can be set according to the density and area size of the through holes on both sides of the network security device 30, so that the bracket assembly 10 does not affect the heat dissipation of the network security device 30.

[0059] The first fixing member 113 may be a pressure riveting screw, a pressure riveting stud or a cylindrical insert. Optionally, under the premise of ensuring that the first fixing member 113 is located in the accommodating cavity 140, the first fixing member 113 may be arranged on the side of the fixing plate 120 facing the supporting plate 110, or may be arranged on the side of the fixing plate 120 facing the supporting plate 110. Figure 3 As shown, the first fixing member 113 is arranged on the side of the support plate 110 facing the fixing plate 120. The assembly steps of each bracket 100 are as follows: first, the inner pull-out plate 130 is assembled with the support plate 110 or the fixing plate 120, and then the fixing strips 121 on both sides of the fixing plate 120 are neatly fitted with the support plate 110, and finally the fixing plate 120 and the support plate 110 are assembled together by riveting, welding, bonding, screw fastening or clamping to complete the overall structural installation of the bracket 100. The assembled bracket 100 is as shown in FIG. Figure 7 As shown, Figure 7 A schematic structural diagram of a bracket provided in an embodiment of the present application is shown.

[0060] The rear end hanging ear 132 is bent in the direction in which the two brackets 100 are separated from each other. The way in which it is fixedly connected to the rear column 22 of the cabinet can refer to the way in which the front end hanging ear 111 is fixedly connected to the front column 21 of the cabinet, which will not be repeated here. It should be noted that in the present application, the pull-out mainboard 131 is partially located in the accommodating cavity 140 and partially located outside the accommodating cavity 140, and the rear end hanging ear 132 is always located outside the accommodating cavity 140. By pushing the pull-out mainboard 131 in the direction of the through hole array (114, 122), or pulling the pull-out mainboard 131 in the opposite direction, the pull-out mainboard 131 slides in the accommodating cavity 140, that is, it is telescoped in the accommodating cavity 140.

[0061] The first slide hole 1311 can be set in the middle of the drawer main board 131, and the width of the first slide hole 1311 is set slightly larger than the maximum width of the cross-sectional area of ​​the first fixing member 113, so that the first fixing member 113 can be inserted into the first slide hole 1311. After the first fixing member 113 on the fixing plate 120 is inserted into the first slide hole 1311, the drawer main board 131 is slidably connected with the fixing plate 120; Figure 4 and Figure 8 As shown, after the first fixing member 113 on the support plate 110 is inserted into the first slide hole 1311, the main plate 131 is pulled out and slidably connected with the support plate 110. Figure 8When the drawable main board 131 is pushed in the direction indicated by the straight arrow in the middle (in the direction indicated by the straight arrow in the middle), the length of the bracket 100 gradually decreases until the first fixing member 113 is exactly at the edge of the first slide hole 1311, so as to prevent the drawable main board 131 from being pushed excessively into the accommodating cavity 140 and causing damage to the accommodating cavity 140. At this time, the length of the bracket 100 is the smallest; when the drawable main board 131 is pulled in the opposite direction of the through hole array (114, 122), the length of the bracket 100 gradually increases until the first fixing member 113 is exactly at the other edge of the first slide hole 1311, so as to prevent the drawable main board 131 from being completely pulled out of the accommodating cavity 140. At this time, the length of the bracket 100 is the largest. In this case, the first fixing member 113 can limit the extreme position of the drawable main board 131 being pushed into the accommodating cavity 140 and pulled out of the accommodating cavity 140, which can not only prevent the drawable main board 131 from being pushed excessively and colliding with the inner side of the accommodating cavity 140, but also prevent the drawable main board 131 from being completely pulled out of the accommodating cavity 140.

[0062] In this case, the drawer mainboard 131 of each bracket 100 is pulled out to a suitable distance, and the two brackets 100 are respectively mounted and fixed on the front column 21 and the rear column 22 of the cabinet through the front hanging ears 111 and the rear hanging ears 132, and then the network security device 30 is placed on the bracket assembly 10, and the support plates 112 on both sides can carry the network security device 30. According to the different spacings between the front column 21 and the rear column 22 of the cabinet 20, the telescopic length of the bracket 100 can be adjusted, so that the bracket assembly 10 can adapt to network security devices 30 of various depths.

[0063] The bracket assembly 10 provided in the embodiment of the present application is configured such that, for each bracket 100 arranged at intervals, the edge of one end of the support plate 110 is bent outward to form a front end ear 111, and the edge of one side is bent inward to form a support flat plate 112, so that the support plate 110 can be installed on the front column 21 of the cabinet to carry the network security device 30; and, by recessing the support plate 110 or the fixing plate 120 in a direction away from each other, and by fixing the fixing plate 120 to the side of the support plate 110 away from the support flat plate 112, the support plate 110 and the fixing plate 120 are connected. A accommodating cavity 140 is formed in between; a rear end ear 132 is formed by bending outwardly at one end edge of the pull-out main board 131, so that the pull-out main board 131 can be installed on the rear column 22 of the cabinet. Furthermore, by opening a first slide hole 1311 on the pull-out main board 131, and arranging a first fixing member 113 on one side of the support plate 110 or the fixing plate 120 and in the accommodating cavity 140, and passing the first fixing member 113 through the first slide hole 1311, the pull-out main board 131 can be extended and retracted in the accommodating cavity 140 to adjust the length of each bracket 100. In the above manner, the bracket assembly 10 can adapt to cabinet columns with different spacings, so that the bracket assembly 10 can be installed on cabinets 20 of different sizes, and then carry network security devices 30 of different depths; and, there is no need to open a hole in the network security device 30, and the network security device 30 can be directly placed on the supporting plate 112 of the brackets 100 on both sides, thereby reducing the use cost of the network security device 30; further, since the pull-out mainboard 131 is retracted in the accommodating cavity 140 between the support plate 110 and the fixed plate 120, the sliding connection between the pull-out mainboard 131 and the support plate 110 or the fixed plate 120 is more stable, thereby improving the structural domain stability of the bracket assembly 10 and enhancing the ability of the bracket assembly 10 to carry the network security device 30.

[0064] In order to enhance the structural strength of the bracket 100, the present application further proposes an implementation method, please continue to refer to Figure 4 and Figure 5 As shown in the figure, the support plate 110 is provided with a first reinforcing rib 115 protruding toward the fixed plate 120 along its length direction. The drawer main board 131 is provided with a second reinforcing rib 1312 protruding toward the support plate 110 at a position corresponding to the first reinforcing rib 115. When the drawer main board 131 slides, the first reinforcing rib 115 and the second reinforcing rib 1312 abut against each other.

[0065] Since the network security device 30 is placed on the support plate 112 of the bracket 100, the force applied to the support plate 110 is relatively large, therefore, the first reinforcing rib 115 is provided on the support plate 110 along the length direction, which can increase the structural strength of the support plate 110 and effectively prevent the deformation of the support plate 110. Similarly, the second reinforcing rib 1312 is provided on the pull-out main board 131 at a position corresponding to the first reinforcing rib 115, which can increase the strength of the pull-out main board 131 and prevent the deformation of the pull-out main board 131.

[0066] For example, taking the first fixing member 113 being set on the support plate 110 as an example, two first reinforcing ribs 115 can be respectively protruded on both sides of the first fixing member 113 on the support plate 110, and correspondingly, corresponding second reinforcing ribs 1312 are protruded on the pull-out main board 131 to further strengthen the structural strength of the support plate 110 and the pull-out main board 131.

[0067] It should be noted that the position where the first reinforcing rib 115 is protruded from the support plate 110 does not conflict with the position where the through hole array 114 is set, that is, the through hole array 114 is opened at one end of the support plate 110 where the front end hanging ear 111 is set, and the first reinforcing rib 115 is protruded from the other end of the support plate 110, and the length of the first reinforcing rib 115 can be greater than the length occupied by the through hole array 114, so as to greatly increase the structural strength of the support plate 110. The second reinforcing rib 1312 can extend to both ends of the drawable main board 131, so as to maximize the structural strength of the drawable main board 131.

[0068] Furthermore, if Figure 5 As shown, in order to make the pull-out main board 131 easier to slide in the accommodating cavity 140, a first reinforcing rib 115 is provided on the support plate 110 protruding toward the fixed plate 120, and a second reinforcing rib 1312 is provided on the pull-out main board 131 protruding toward the support plate 110, so that a gap is formed between the support plate 110 and the pull-out main board 131, and a gap is formed between the pull-out main board 131 and the fixed plate 120, thereby reducing the contact area between the pull-out main board 131 and the support plate 110 and the fixed plate 120 respectively, thereby reducing the resistance of the pull-out main board 131 to sliding in the accommodating cavity 140.

[0069] When the pull-out mainboard 131 is extended and retracted in the accommodating cavity 140 , the first reinforcing rib 115 and the second reinforcing rib 1312 abut against each other, which can prevent the pull-out mainboard 131 from shaking significantly in the accommodating cavity 140 or even colliding with the two sides of the accommodating cavity 140 , thereby increasing the stability of the bracket 100 .

[0070] In some embodiments, Figure 5As shown, a smaller gap can be reserved between the first reinforcing rib 115 and the second reinforcing rib 1312 , and a reduced gap can be reserved between the side of the drawer main board 131 away from the first reinforcing rib 115 and the fixed plate 120 , so as to facilitate drawing and pulling of the drawer main board 131 in the accommodating cavity 140 .

[0071] In some embodiments, the first reinforcing rib 115 and the second reinforcing rib 1312 can be slender strips of plate material, which are respectively fixed to the side of the support plate 110 facing the fixed plate 120 and the side of the pull-out main board 131 facing the support plate 110 by welding, riveting or bonding.

[0072] In order to increase the structural strength of the front end hanging ear 111 and the rear end hanging ear 132, the present application further proposes an implementation method, please continue to refer to Figure 4 As shown in the figure, the bracket 100 further includes two L-shaped reinforcement members 150, each L-shaped reinforcement member 150 includes a second reinforcement plate 151 and a third reinforcement plate 152 connected to each other. The second reinforcement plate 151 of one L-shaped reinforcement member 150 is fixedly connected to one end of the support plate 110 bent to form a front end hanging ear 111, and the third reinforcement plate 152 is fixedly connected to the front end hanging ear 111, and the L-shaped reinforcement member 150 is used to strengthen the connection strength at the bend between the front end hanging ear 111 and the support plate 110. The second reinforcement plate 151 of the other L-shaped reinforcement member 150 is fixedly connected to one end of the drawable main board 131 bent to form a rear end hanging ear 132, and the third reinforcement plate 152 is fixedly connected to the rear end hanging ear 132, and the L-shaped reinforcement member 150 is used to strengthen the connection strength at the bend between the rear end hanging ear 132 and the drawable main board 131.

[0073] In this embodiment, two L-shaped reinforcement members 150 can be respectively arranged in front of the front end hanging ear 111 and the rear end hanging ear 132 (not shown in the figure), or Figure 4 As shown, the rear sides of the front hanging ears 111 and the rear hanging ears 132 are respectively arranged ( Figure 4 The side pointed by the dotted arrow is the back side).

[0074] The area sizes of the front hanging ear 111 and the rear hanging ear 132 can be set to be the same or different. When the area sizes of the front hanging ear 111 and the rear hanging ear 132 are the same, the area sizes of the third reinforcing plates 152 of the two L-shaped reinforcement members 150 are the same; when the area sizes of the front hanging ear 111 and the rear hanging ear 132 are different, the area sizes of the third reinforcing plates 152 of the two L-shaped reinforcement members 150 can be determined according to the areas of the front hanging ear 111 and the rear hanging ear 132 respectively. In this case, it can be ensured that when the third reinforcing plate 152 is fixedly connected to the front hanging ear 111 and the rear hanging ear 132, the third reinforcing plate 152 can completely cover the front hanging ear 111 and the rear hanging ear 132, thereby maximizing the structural strength of the front hanging ear 111 and the rear hanging ear 132. On the premise of ensuring that the second reinforcement plate 151 can be fit and fixedly connected to the end of the support plate 110 close to the front end ear 111 and the end of the pull-out main board 131 close to the rear end ear 132, the area size of the second reinforcement plate 151 can be set according to the actual structural strength requirements of the front end ear 111 and the rear end ear 132.

[0075] Specifically, the third reinforcing plate 152 of one L-shaped reinforcing member 150 can be fixedly connected to the front end hanging ear 111 by riveting, welding, bonding, screwing or clamping, and the second reinforcing plate 151 of the L-shaped reinforcing member 150 can be fixedly connected to the support plate 110. Similarly, the third reinforcing plate 152 of another L-shaped reinforcing member 150 can be fixedly connected to the rear end hanging ear 132 by riveting, welding, bonding, screwing or clamping, and the second reinforcing plate 151 of the L-shaped reinforcing member 150 can be fixedly connected to the drawer main board 131.

[0076] In this way, the wall thickness and structural strength of the front end hanging ear 111 and the rear end hanging ear 132 can be enhanced, as well as the wall thickness and structural strength of the bending part between the support plate 110 and the front end hanging ear 111 and the bending part between the pull-out main board 131 and the rear end hanging ear 132 can be enhanced, thereby reducing the deformation risk of the front end hanging ear 111 and the rear end hanging ear 132, thereby enhancing the stability between the front end hanging ear 111 and the front column 21 of the cabinet, as well as the stability between the rear end hanging ear 132 and the rear column 22 of the cabinet.

[0077] In order to limit the movement of the drawable main board 131 when the length of the bracket 100 is the smallest so as to improve the structural stability of the bracket 100, the present application further proposes an implementation method, please continue to refer to Figure 4 and Figure 8 , and combined with Fig. 9 , Fig. 9The schematic diagram of the structure of the drawer plate provided by the embodiment of the present application is shown. As shown in the figure, the end of the support plate 110 bent to form the front end hanging ear 111 is provided with a through hole array 114, and the end of the support plate 110 away from the front end hanging ear 111 is provided with a locking hole 116. The drawer main board 131 is provided with a limit member 1313 at one end provided with the rear end hanging ear 132. When the drawer main board 131 slides to the locking position toward the through hole array 114, the limit member 1313 is engaged with the locking hole 116 to limit the sliding of the drawer main board 131. After the limit member 1313 is withdrawn from the locking hole 116, the drawer main board 131 can be retracted in the accommodating cavity 140.

[0078] The through hole array 114 shown in the embodiment of the present application can refer to the aforementioned Figure 4 The through hole array 114 shown in the embodiment will not be described in detail here.

[0079] The shape of the locking hole 116 can be triangular, circular, rectangular or polygonal, etc. The stopper 1313 can be made of a material with a certain elasticity (such as thin stainless steel, plastic material, etc.), which can sink when compressed by external force, and can bounce back and return to its original state when the external force is removed. The locking position can refer to the position where the pull-out main board 131 slides toward the through hole array 114 until the first fixing member 113 is at the edge of the first slide hole 1311.

[0080] When the drawable mainboard 131 slides toward the through hole array 114 to the locking position, the stopper 1313 on the drawable mainboard 131 sinks under the compression of the support plate 110. When the drawable mainboard 131 slides to the locking position, the stopper 1313 slides out to the locking hole 116, pops up and returns to its original state, and then the stopper 1313 is stuck on the cross section of the locking hole 116 and engages with the locking hole 116, thereby limiting the movement of the drawable mainboard 131 along its length and width. When the drawable mainboard 131 needs to be pulled out of the accommodating cavity 140, pressing the stopper 1313 downward can make the stopper 1313 withdraw from the locking hole 116, and then the drawable mainboard 131 can slide in the accommodating cavity 140, for example, pulled outward to increase the length of the bracket 100.

[0081] Through the above method, the limit piece 1313 on the support plate 110 can slide the pull-out main board 131 toward the through hole array 114 to a locking position, that is, engage the locking hole 116 when the length of the bracket 100 is minimum, thereby limiting the movement of the pull-out main board 131 and ensuring the structural stability of the bracket 100; when the pull-out main board 131 needs to be pulled out from the accommodating cavity 140 to increase the length of the bracket 100, the limit piece 1313 is withdrawn from the locking hole 116, and the pull-out main board 131 can be slidable in the accommodating cavity 140.

[0082] In order to lock the drawable main board 131, the present application further proposes an implementation method, please continue to refer to Figure 8 and Fig. 9 , and combined with Fig.10 , Fig.10 The schematic diagram of the structure of the support plate and the pull-out plate provided in the embodiment of the present application is shown. As shown in the figure, one end of the limiter 1313 is fixedly connected to the pull-out main board 131, and the other end is suspended. A button 1314 is provided at the suspended end of the limiter 1313. A position-avoiding hole 1315 is provided on the pull-out main board 131 at a position opposite to the suspended part of the limiter 1313. The position-avoiding hole 1315 is used to provide movement space for the suspended part of the limiter 1313 and the button 1314. A protrusion 1316 is provided on the side of the limiter 1313 away from the position-avoiding hole 1315. When the pull-out main board 131 slides to the locking position toward the through hole array 114, the protrusion 1316 is engaged with the locking hole 116. When the button 1314 is moved toward the position-avoiding hole 1315, the protrusion 1316 withdraws from the locking hole 116.

[0083] One end of the limiting member 1313 can be fixed to the drawer main board 131 by riveting, welding, bonding or screw fastening.

[0084] The avoidance hole 1315 of the embodiment of the present application may be circular, rectangular or polygonal, etc., and is preferably in the same shape as the stopper 1313. The avoidance hole 1315 is located opposite to the suspended portion of the stopper 1313, so that the avoidance hole 1315 can reserve movement space for the suspended portion of the stopper 1313 and the button 1314 disposed at one end of the suspension, so that when the drawer main board 131 slides toward the through hole array 114, the stopper 1313 can have enough space to avoid under the compression of the support plate 110, so that the drawer main board 131 continues to slide toward the through hole array 114 until it slides to the locked position.

[0085] When the drawer main board 131 slides to the locked position, the suspended part of the limiter 1313, the protrusion 1316 and the button 1314 avoid the avoidance hole 1315 under the compression of the support plate 110. When the drawer main board 131 slides to the locked position, the protrusion 1316 of the limiter 1313 slides out into the locking hole 116, and the suspended part of the limiter 1313 pops up and returns to its original state. At this time, the protrusion 1316 pops up and engages with the locking hole 116 to limit the movement of the drawer main board 131 along its length and width directions. When it is necessary to pull the pull-out main board 131 out of the accommodating cavity 140, push the button 1314 toward the avoidance hole 1315, that is, press the button 1314 toward the avoidance hole 1315, and the suspended part of the limit member 1313 moves toward the avoidance hole 1315, and at the same time, the protrusion 1316 also moves toward the avoidance hole 1315 with the suspended part, so that the protrusion 1316 withdraws from the locking hole 116, and then the pull-out main board 131 can be pulled out to increase the length of the bracket 100.

[0086] In order to improve the support capability of the bracket assembly 10 for the network security device 30, the present application further proposes an implementation method, see Fig.11 , Fig.11 A structural schematic diagram of the bracket assembly provided in an embodiment of the present application is shown. As shown in the figure, the bracket assembly 10 also includes a bottom support plate 160. The bottom support plate 160 is arranged between the two brackets 100. The two ends of the bottom support plate 160 are respectively connected to the support plates 110 of the two brackets 100. The bottom support plate 160 is used to support the network security device 30.

[0087] When the length of the two brackets 100 is greater than the depth of the network security device 30, the network security device 30 is usually placed near the front end ear 111 to facilitate cable management and regular configuration and maintenance. In this case, the overall weight of the network security device 30 is mostly borne by one end of the two brackets 100 close to the front end ear 111, which can easily cause the front end ear 111 and the front support plate 112 to deform, and easily cause the front end ear 111 to detach from the front column 21 of the cabinet.

[0088] Therefore, the bottom support plate 160 can be arranged between the two brackets 100 near the front end hanging ear 111, or in the middle between the two brackets 100, and the two ends of the bottom support plate 160 are respectively connected to the support plate 110, so that the bottom support plate 160 can support the network security device 30 together with the support plate 112, which not only reduces the load of the support plate 112 on both sides, but also reduces the load of the front end hanging ear 111, thereby improving the support capacity of the bracket assembly 10 for the network security device 30. Among them, the two ends of the bottom support plate 160 can be fixedly connected to the support plate 110, for example, by welding, bonding or riveting; the two ends of the bottom support plate 160 can also be detachably connected to the support plate 110, for example, by snapping, bolting, hinged or plugging.

[0089] In order to adapt to network security devices 30 of different widths, the present application further proposes an implementation method, see Figure 12-14 , Fig.12 The structure diagram of the bottom support plate provided in the embodiment of the present application is shown. Fig.13 The cross-sectional structure diagram of the bottom plate provided in the embodiment of the present application is shown. Fig.14 The schematic diagram of the structure of the bracket assembly provided by the embodiment of the present application is shown. As shown in the figure, the bottom support plate 160 includes a bottom plate 161, a left pull-out plate 162 and a right pull-out plate 163. The two sides of the bottom plate 161 in the length direction are bent toward each other to form a slide groove 1611; the left pull-out plate 162 and the right pull-out plate 163 are inserted into the slide groove 1611 toward each other, and the left pull-out plate 162 and the right pull-out plate 163 can slide in the slide groove 1611, and the two opposite ends of the left pull-out plate 162 and the right pull-out plate 163 are respectively connected to the two support flat plates 112.

[0090] like Fig.13 As shown, the cross section of the bottom plate 161 is a flat C-shaped structure, and the two sides of the C-shaped structure are bent to form the slide grooves 1611. The two opposite ends of the left pull-out plate 162 and the right pull-out plate 163 can be connected to the two support plates 112 by fixed connection methods such as welding, bonding or riveting, or by active connection methods such as clamping, bolting, hinged or plugging.

[0091] Among them, the left pull-out plate 162 and the right pull-out plate 163 can be completely the same symmetrical structure. The left pull-out plate 162 and the right pull-out plate 163 are inserted into the slide groove 1611 facing each other, and the left pull-out plate 162 and the right pull-out plate 163 can slide on the bottom plate 161. When the left pull-out plate 162 and the right pull-out plate 163 slide toward each other in the slide groove 1611, the length of the bottom support plate 160 is reduced, thereby reducing the distance between the two brackets 100; when the left pull-out plate 162 and the right pull-out plate 163 slide away from each other, the length of the bottom support plate 160 is increased, thereby increasing the distance between the two brackets 100. In this way, the length of the bottom support plate 160 can be changed, and then the width of the bracket assembly 10 can be changed to adapt to network security devices 30 of different widths.

[0092] In order to prevent the left pull-out plate 162 and the right pull-out plate 163 from colliding with each other and being completely pulled out of the slide slot 1611, the present application further proposes an implementation method, please continue to refer to Fig.12 and Fig.14 As shown in the figure, the left pull-out plate 162 is provided with a second slide hole 1621, and the right pull-out plate 163 is provided with a third slide hole 1631. The second fixing members 1612 are symmetrically provided at both ends of the bottom plate 161, and the second fixing members 1612 at both ends of the bottom plate 161 are respectively penetrated through the second slide hole 1621 and the third slide hole 1631 to limit the sliding distance of the left pull-out plate 162 and the right pull-out plate 163 respectively.

[0093] Specifically, the second fixing member 1612 may be a pressure riveting screw, a pressure riveting stud or a cylindrical insert, etc. The second slide hole 1621 and the third slide hole 1631 may be respectively arranged in the middle of the left pull-out plate 162 and the right pull-out plate 163, and the width of the second slide hole 1621 and the third slide hole 1631 is slightly larger than the maximum width of the cross-sectional area of ​​the second fixing member 1612, so that the second fixing member 1612 can be respectively inserted into the second slide hole 1621 and the third slide hole 1631.

[0094] The second fixing member 1612 is respectively provided in the second slide hole 1621 and the third slide hole 1631, so that the left pull-out plate 162 and the right pull-out plate 163 are both slidably connected to the bottom plate 161. The left pull-out plate 162 can be kept stationary and the right pull-out plate 163 can be slid, the right pull-out plate 163 can be kept and the left pull-out plate 162 can be slid, and the left pull-out plate 162 and the right pull-out plate 163 can be slid simultaneously.

[0095] Taking the simultaneous sliding of the left and right drawer plates 162 and 163 as an example, when the left and right drawer plates 162 and 163 slide toward each other until the second fixing member 1612 is respectively located at the outermost edge of the second slide hole 1621 and the third slide hole 1631, the second fixing member 1612 can prevent the left and right drawer plates 162 and 163 from continuing to slide toward each other, so that there is a gap between the left and right drawer plates 162 and 163, thereby avoiding collision between the left and right drawer plates 162 and 163. At this time, the length of the bottom support plate 160 is at its maximum. When the left pull-out plate 162 and the right pull-out plate 163 slide away from each other and slide to the other extreme edge of the second slide hole 1621 and the third slide hole 1631 respectively, the second fixing member 1612 can prevent the left pull-out plate 162 and the right pull-out plate 163 from continuing to slide away from each other, thereby preventing the left pull-out plate 162 and the right pull-out plate 163 from being completely pulled out from the bottom plate 161. At this time, the length of the bottom support plate 160 is the largest, and the distance between the two brackets 100 is the largest.

[0096] The second fixing members 1612 at both ends of the bottom plate 161 are symmetrically arranged, and the second fixing members 1612 can limit the left pull-out plate 162 and the right pull-out plate 163 to slide toward and away from each other by the same distance, so as to better control the distance between the two brackets 100.

[0097] Optionally, two second fixing members 1612 may be symmetrically provided at both ends of the bottom plate 161. In this case, when the left drawer plate 162 and the right drawer plate 163 slide toward each other until the two second fixing members 1612 at the edges are located at the outermost edges of the second slide hole 1621 and the third slide hole 1631, respectively, the two second fixing members 1612 at the edges can prevent the left drawer plate 162 and the right drawer plate 163 from continuing to slide toward each other, thereby preventing the left drawer plate 162 and the right drawer plate 163 from sliding toward each other. 2 collides with the right drawer plate 163; when the left drawer plate 162 and the right drawer plate 163 slide away from each other until the two second fixing members 1612 in the middle are respectively located at the other extreme edges of the second slide hole 1621 and the third slide hole 1631, the second fixing member 1612 in the middle can prevent the left drawer plate 162 and the right drawer plate 163 from continuing to slide away from each other, thereby preventing the left drawer plate 162 and the right drawer plate 163 from being completely pulled out of the bottom plate 161.

[0098] like Fig.11 As shown, when the two second fixing members 1612 at the edge are respectively located at the outermost edges of the second slide hole 1621 and the third slide hole 1631, the length of the bottom support plate 160 is the smallest, and the distance between the two brackets 100 is the smallest. In this case, the bracket assembly 10 can be adapted to a cabinet 20 with a standard width of 19 inches; Fig.14As shown, when the two second fixing members 1612 in the middle are respectively located at the other extreme edges of the second slide hole 1621 and the third slide hole 1631, the length of the bottom support plate 160 is the largest, and the distance between the two brackets 100 is the largest. In this case, the bracket assembly 10 can be adapted to a cabinet 20 with a standard width of 23 inches. In addition, when the width of the cabinet 20 is a non-standard size, the left pull-out plate 162 and the right pull-out plate 163 can be pulled out in opposite directions to a suitable distance according to actual conditions, so that the length of the bottom support plate 160 can adapt to the width of the cabinet 20.

[0099] In order to facilitate fixing the two ends of the bottom support plate 160 on the brackets 100 on both sides, the present application further proposes an implementation method, please continue to refer to Figure 6 , Fig.11 and Fig.12 As shown in the figure, when the edge of one side of each support plate 112 is bent back toward the bottom of the support plate 112 to form the first reinforcing plate 1121, each support plate 112 is provided with a notch 1122 at one end where the short side is located, and each first reinforcing plate 1121 is provided with a through hole 1121a at a position corresponding to the notch 1122.
