[0038] In order to solve the problems in the prior art, the present application provides a shell and a network video recorder, which has simple structure and is convenient to disassemble to ensure quick maintenance in later period.

[0039] As Figures 1-12As shown, the embodiment of the present application provides a shell, comprising: a bottom shell 1, a top shell 2 and a fastener 3.

[0040] The top of the bottom shell 1 is provided with an opening 11, and the bottom shell 1 has a lead-in edge 12 extending along a first direction X.

[0041] The top shell 2 has a guide edge 21 extending along the first direction X, and the guide edge 21 is in sliding fit with the lead-in edge 12, used for limiting the top shell 2 and the bottom shell 1 along a second direction Y, and the top shell 2 includes a first state of covering the opening 11.

[0042] The fastener 3 is arranged on one of the bottom shell 1 and the top shell 2 and detachably connected with the other one, used for limiting the top shell 2 and the bottom shell 1 along the first direction X; wherein the first direction X is perpendicular to the second direction Y. Specifically, the fastener 3 can be arranged on the bottom shell 1 and detachably connected with the top shell 2, and when connected with the top shell 2, the fastener 3 completes the limitation of the top shell 2 and the bottom shell 1 along the first direction X; the fastener 3 can also be arranged on the top shell 2 and detachably connected with the bottom shell 1, and when connected with the bottom shell 1, the fastener 3 completes the limitation of the top shell 2 and the bottom shell 1 along the first direction X.

[0043] In the present application, the guide edge 21 of the top shell 2 slides along the lead-in edge 12 of the bottom shell 1 to limit the top shell 2 and the bottom shell 1 along the first direction X, and the fastener 3 connects the top shell 2 and the bottom shell 1 to limit the top shell 2 and the bottom shell 1 along the second direction Y, so that the top shell 2 is stably kept in the first state, and when disassembled later, the bottom shell 1 and the top shell 2 are separated by the fastener 3, and then the top shell 2 is slid in the direction opposite to the installation direction to complete the disassembly of the top shell 2 and the bottom shell 1, so that the overall structure is simple and convenient for disassembly to ensure that the device can be quickly maintained later.

[0044] Specifically, the bottom shell 1 includes a bottom plate and side plates arranged around the bottom plate, and the bottom plate and the four side plates enclose the bottom shell 1 with the opening 11 at the top, wherein two opposite side plates are provided with the lead-in edge 12; the top shell 2 includes a top plate and guide edges 21 arranged at both ends of the top plate along the second direction Y, and the two guide edges 21 are located outside the two lead-in edges 12, thereby limiting the top shell 2 and the bottom shell 1 in two directions along the second direction Y.

[0045] In the related art, the shell of the existing network video recorder is generally closed by screw fastening, glueing, buckling, door locking and the like. Among them, the glueing method cannot be disassembled twice; the buckling and door locking methods need to increase many accessories, increasing the number of parts and cost; although the screw fastening method can be disassembled twice and does not need to increase additional parts, it needs a screwdriver to disassemble multiple screws, which is not convenient for quick maintenance.

[0046] In the embodiment of the present application, only the bottom shell 1, the top shell 2 and the fastener 3 are included, and the fastener 3 does not need to be arranged too much, and generally one to two fasteners can be selected, without the need to arrange parts such as buckles and door locks, so that the structure is simple, the cost is reduced, and compared with the form of installation through multiple screws, the present application can complete the limiting of the bottom shell 1 and the top shell 2 in the second direction Y through the guide edge 12 and the guide edge 21, and can complete the limiting of the bottom shell 1 and the top shell 2 in the first direction X through the fastener 3, so that only the fastener 3 is needed to connect or separate the bottom shell 1 and the top shell 2 in the dismounting process, which is convenient for dismounting and facilitates quick maintenance.

[0047] As shown in Figure 3 In some embodiments, the bottom shell 1 is provided with a stop plate 13 at one end along the first direction X, and the stop plate 13 is provided with a threaded hole 131; the top shell 2 is provided with a mounting plate 22 parallel to the stop plate 13 at one end along the first direction X, and the fastener 3 is rotatably arranged on the mounting plate 22 and used for threadedly connecting the threaded hole 131.

[0048] In the present application, the axis of the threaded hole 131 is arranged along the first direction X, the fastener 3 is a bolt of the anti-loosening stripe handle, the bolt is threadedly connected with the threaded hole 131, the stop plate 13 is connected with the mounting plate 22, and the effective fixing of the top shell 2 and the bottom shell 1 in the first direction X is realized. When the top shell 2 is dismounted, the bolt only needs to be loosened, and when the top shell 2 is fixed, the bolt only needs to be tightened, which is convenient to operate.

[0049] Moreover, the bolt of the anti-loosening stripe handle can effectively prevent the bolt from loosening, and the reliability of the connection of the top shell 2 and the bottom shell 1 is ensured.

[0050] Specifically, when the top shell 2 is in the first state, the mounting plate 22 is attached to the stop plate 13 and locked by the fastener 3, and the connection of the bottom shell 1 and the top shell 2 in the first direction X is realized.

[0051] Alternatively, the fastener 3 can also be a clamping block and a clamping groove, one of the clamping block and the clamping groove is arranged on the stop plate 13 of the bottom shell 1, and the other is arranged on the mounting plate 22 of the top shell 2, and the clamping block and the clamping groove are clamped to complete the limiting of the bottom shell 1 and the top shell 2 in the first direction X.

[0052] In some embodiments, a pressing structure is arranged between the bottom shell 1 and the top shell 2, and the pressing structure is used for limiting the top shell 2 and the bottom shell 1 along a third direction Z; wherein the third direction Z is perpendicular to the first direction X and the second direction Y.

[0053] Specifically, the first direction X is the length direction of the shell, the second direction Y is the width direction of the shell, and the third direction Z is the height direction of the shell. The pressing structure between the bottom shell 1 and the top shell 2 limits the bottom shell 1 and the top shell 2 in the third direction Z. The bottom shell 1 and the top shell 2 are limited from three aspects, so that the top shell 2 can be stably kept in the first state, and the reliability of the connection between the top shell 2 and the bottom shell 1 is further improved.

[0054] In some embodiments, the pressing structure includes a folding edge 14 arranged on the bottom shell 1 and a buckling edge 23 arranged on the top shell 2. When the top shell 2 is in the first state, the buckling edge 23 is clamped with the folding edge 14.

[0055] In this application, as the top shell 2 slides along the first direction X, when the top shell 2 slides to the first state, the buckling edge 23 on the top shell 2 is clamped with the folding edge 14 on the bottom shell 1, thereby limiting the top shell 2 and the bottom shell 1 in the third direction Z. The limiting of the top shell 2 and the bottom shell 1 in the third direction Z can be automatically completed during the sliding process. The guide edge 12 and the guide edge 21 limit the top shell 2 and the bottom shell 1 in the second direction Y. Then, the fastener 3 limits the top shell 2 and the bottom shell 1 in the first direction X, thereby effectively fixing the bottom shell 1 and the top shell 2. When disassembling the top shell 2, only the fastener 3 needs to be loosened and tightened, which is convenient for disassembly and maintenance.

[0056] In some embodiments, the direction of the buckling edge 23 is the same as the direction in which the top shell 2 slides to the first state, and the direction of the folding edge 14 is opposite to the direction in which the top shell 2 slides to the first state.

[0057] In this application, the sliding direction of the top shell 2 during installation is defined as the installation direction, and the sliding direction of the top shell 2 during disassembly is defined as the disassembly direction. The installation direction is opposite to the disassembly direction. The direction of the buckling edge 23 is the same as the installation direction, and the direction of the folding edge 14 is the same as the disassembly direction. Therefore, the clamping and separation of the buckling edge 23 and the folding edge 14 can be automatically completed during the sliding process of the top shell 2, which is convenient for disassembly.

[0058] As shown in Figure 4 , 7 , 8, 10, in some embodiments, the folding edge 14 includes a first folding edge 141 and a second folding edge 142, and the first folding edge 141 and the second folding edge 142 are arranged at both ends of the shell along the first direction X. The buckling edge 23 includes a first buckling edge 231 and a second buckling edge 232, and the first buckling edge 231 and the second buckling edge 232 are arranged at both ends of the top shell 2 along the first direction X. The first buckling edge 231 is used for clamping the first folding edge 141, and the second buckling edge 232 is used for clamping the second folding edge 142.

[0059] In the present application, when the top shell 2 is in the first state, the first buckle edge 231 is clamped with the first folded edge 141, and the second buckle edge 232 is clamped with the second folded edge 142, thereby pressing the two ends of the top shell 2 and the bottom shell 1 in the first direction X respectively, so that the top shell 2 can be pressed on the bottom shell 1, further improving the limiting effect of the bottom shell 1 and the top shell 2 in the third direction Z.

[0060] In some embodiments, the top shell 2 is provided with a first flanging structure 24 at both ends in the first direction X respectively, and the first buckle edge 231 and the second buckle edge 232 are arranged at the first flanging structure 24.

[0061] In the present application, by arranging the first flanging structure 24 at both ends of the top shell 2 in the first direction X respectively, the thickness of the top shell 2 at both ends in the first direction X is increased, thereby improving the structural strength, and by arranging the first buckle edge 231 and the second buckle edge 232 at the first flanging structure 24 respectively, the effect of not hollowing out the outer surface of the shell can be solved, the sealing effect is improved, and the appearance is more beautiful.

[0062] As shown in Figure 11 , 12 Specifically, the top shell 2 and the bottom shell 1 are integrally formed by sheet metal stamping, and the first flanging structure 24, the first buckle edge 231 and the second buckle edge 232 can be directly formed in the stamping process, without the need for subsequent welding and other processing of the first buckle edge 231 and the second buckle edge 232, thereby ensuring the structural strength of the first buckle edge 231 and the second buckle edge 232, and the first buckle edge 231 and the second buckle edge 232 are located at the first flanging structure 24, without affecting the appearance of the top shell 2.

[0063] In some embodiments, the pressing structure further comprises a buckle groove 15 arranged on the guide-in edge 12, and a third buckle edge 25 arranged on the guide edge 21; wherein when the top shell 2 is in the first state, the third buckle edge 25 is clamped into the buckle groove 15.

[0064] In the present application, as the top shell 2 slides in the first direction X, the third buckle edge 25 can be clamped into the buckle groove 15, further limiting the top shell 2 and the bottom shell 1 in the third direction Z. Specifically, the buckle groove 15 is located between the first folded edge 141 and the second folded edge 142, and the third buckle edge 25 is located between the first buckle edge 231 and the second buckle edge 232, thereby limiting the middle part of the top shell 2 and the bottom shell 1 in the first direction X, so that the top shell 2 can be effectively pressed on the bottom shell 1, further improving the fixing effect of the top shell 2 and the bottom shell 1.

[0065] Specifically, the number of the buckle slot 15 and the third buckle edge 25 can be a pair, that is, two buckle slots 15 are arranged on the two guide-in edges 12 respectively, and two third buckle edges 25 are arranged on the two guide edges 21 respectively; the number of the buckle slot 15 and the third buckle edge 25 can also be multiple pairs, and the multiple pairs of buckle slots 15 and third buckle edges 25 are arranged at intervals along the first direction X. For the shell with a relatively long length in the first direction X, the number of the buckle slot 15 and the third buckle edge 25 can be increased to ensure the pressing effect of the top shell 2 on the bottom shell 1.

[0066] In some embodiments, the guide-in cut of the buckle slot 15 is opposite to the direction in which the top shell 2 slides to the first state.

[0067] In the present application, when the top shell 2 is installed, the third buckle edge 25 on the top shell 2 is first aligned with the guide-in cut of the buckle slot 15, the third buckle edge 25 enters the buckle slot 15 through the guide-in cut, and the third buckle edge 25 is clamped with the buckle slot 15 as the top shell 2 slides along the first direction X, thereby fixing the top shell 2 and the bottom shell 1 at this position. When the top shell 2 is disassembled, the top shell 2 is first slid along the disassembly direction so that the third buckle edge 25 on the top shell 2 slides at the guide-in cut, and then the top shell 2 can be separated from the bottom shell 1. The clamping and separation of the third buckle edge 25 and the buckle slot 15 can be automatically realized during the sliding process of the top shell 2, which is convenient to operate.

[0068] Specifically, the second flanging structure is adopted at the guide-in edge 12 of the bottom shell 1, which can improve the structural strength of the guide-in edge 12 and the smoothness of the contact position between the guide-in edge 12 and the top shell 2, thereby facilitating the sliding, disassembly and assembly of the top shell 2.

[0069] The third flanging structure is arranged at the guide edge 21 of the top shell 2 to increase the structural strength of the guide edge 21 of the top shell 2. The third buckle edge 25 is arranged at the third flanging structure, which can realize the effect of non-hollowing of the outer surface of the top shell 2.

[0070] The shell is slid along the guide-in edge 12 of the bottom shell 1 through the guide edge 21 of the top shell 2 to limit the top shell 2 and the bottom shell 1 along the first direction X, and the top shell 2 and the bottom shell 1 are connected through the fastener 3 to limit the top shell 2 and the bottom shell 1 along the second direction Y, so that the top shell 2 is stably kept in the first state. When disassembled later, the bottom shell 1 and the top shell 2 are separated through the fastener 3, and then the top shell 2 is slid in the direction opposite to the installation direction to complete the disassembly of the top shell 2 and the bottom shell 1. The overall structure is simple and convenient to disassemble to ensure that the shell can be quickly maintained in the later period.

[0071] The present application provides a network video recorder, which comprises the shell.

[0072] The network video recorder is a storage and forwarding part of a network video monitoring system. The network video recorder cooperates with a video encoder or a network camera to complete video recording, storage and forwarding functions. The network video recorder comprises a shell and functional modules in the shell. When the shell is assembled and maintained later, the shell in the application has a simpler structure, does not need buckles and door locks and other parts, and is convenient to disassemble and assemble, thereby realizing later rapid maintenance.
