DETAILED DESCRIPTION

[0016] The following will be combined with the Figs. 1-3 The application is further described in detail.

[0017] The application embodiment discloses a simple plug-in type external structure of a security video recorder hard disk. Figs. 1-3 A simple plug-in type external structure of a security video recorder hard disk mainly comprises a connecting frame 2, an elastic card 3, a mounting notch 4, a slot 5, and a limiting convex strip 6, realizes convenient and stable installation of the security video recorder hard disk, and ensures that the security video recorder hard disk is not disturbed by external factors such as vibration during equipment operation.

[0018] Refer to Fig. 1 and Fig. 2The connecting frame 2 is bolted on both sides of the security recorder hard disk 1, and the connecting frame 2 is required to be installed to realize the adaptive connection of the security recorder hard disk 1 and the security recorder host. The connecting frame 2 is composed of an L-shaped plate 201 and a U-shaped plate 202, both of which are made of high-strength engineering plastic or aluminum alloy material. The engineering plastic has the advantages of light weight, good insulation, and convenient forming, which can reduce the overall structure weight, avoid additional burden on the hard disk operation, and facilitate large-scale production and manufacturing; the aluminum alloy material has high strength and corrosion resistance, and is suitable for occasions with high structural strength requirements or harsh use environment, and the selectability of the two materials can meet the diversified use requirements. The L-shaped plate 201 and the U-shaped plate 202 are both provided with mounting slots 4, and the design precision of the mounting slots 4 is strict, whether a buckle structure or a screw hole structure is adopted, the size precision is strictly controlled, and the fitting precision with the security recorder hard disk 1 is high, so that the close and stable cooperation can ensure that the connecting frame 2 is closely attached to the hard disk 1.

[0019] Referring to Fig. 3 The elastic card 3 is installed on the U-shaped plate 202, and is used to enhance the fixing effect of the security recorder hard disk 1 in the host hard disk slot. The elastic card 3 includes an S-shaped elastic sheet 301 and a plug-in end head 302. The S-shaped elastic sheet 301 is made of high-quality spring steel, and its elasticity and fatigue life are significantly improved through heat treatment process, so that it can always maintain good elastic performance in the long-term frequent use process, and provide durable and stable clamping elastic force for the hard disk. Its surface is galvanized or nickel-plated to effectively prevent rust and ensure reliable work in complex environments such as humidity. The plug-in end head 302 is composed of a connecting sheet 3021 and a cylindrical clamping head 3022, and is made of the same or similar material as the L-shaped plate 201 and the U-shaped plate 202, which ensures the coordination of the overall structure and avoids connection problems caused by material differences. The connecting sheet 3021 is firmly and reliably connected with the S-shaped elastic sheet 301, and can be welded or riveted to ensure that the plug-in end head 302 will not fall off during the hard disk plugging process, and to protect the integrity and functionality of the elastic card 3.

[0020] Referring to Fig. 3The U-shaped plate 202 is provided with a plurality of insertion slots 5 matched with the insertion end 302, the insertion slots 5 are parallel to the inner side edge of the U-shaped plate 202, and the insertion slots 5 and the limiting convex strips 6 are integrally formed with the U-shaped plate 202. For the U-shaped plate 202 made of engineering plastic, the injection molding process is adopted to precisely control the size precision and surface flatness of the insertion slots 5 and the limiting convex strips 6, so that the smooth insertion and extraction of the elastic card 3 is ensured. For the U-shaped plate 202 made of aluminum alloy, the machining process can also achieve the same high precision requirement. When the elastic card 3 is installed, the insertion end 302 is inserted into the corresponding insertion slot 5 on one side or two insertion slots 5 above and below, and the cylindrical clamping head 3022 is smoothly inserted along the insertion slot 5. At this time, since the limiting convex strip 6 is arranged on the inner side of the insertion slot 5, the cylindrical clamping head 3022 is guided to the correct position by the limiting convex strip 6 during the insertion process, so that the insertion end 302 is accurately installed, and the problem that the elastic card 3 is invalid due to installation deviation is effectively avoided, thereby providing protection for the stable fixation of the subsequent hard disk.

[0021] The implementation principle of the simple insertion type external structure of the security recorder hard disk in the embodiment of the application is as follows: when the security recorder hard disk 1 needs to be installed in use, first, according to the hard disk slot layout of the security recorder host, the L-shaped plate 201 and the U-shaped plate 202 of the connecting frame 2 are fixed on the side of the security recorder hard disk 1 through the installation slot 4. Then, the insertion end 302 of the elastic card 3 is inserted into the corresponding insertion slot 5, at this time, the arc-shaped part of the S-shaped elastic sheet 301 protrudes from the edge part of the U-shaped plate 202, when the security recorder hard disk 1 is inserted into the host hard disk slot, the S-shaped elastic sheet 301 is tightly clamped with the positioning slot on the insertion slot, and the elastic force can ensure that the hard disk is stably fixed in the insertion slot, even if the device is disturbed by external interference such as vibration, the hard disk can also be effectively prevented from loosening and shifting.

[0022] Finally, it should be pointed out that in the description of the application, it should be pointed out that unless otherwise specified and limited, the terms "installation", "connection" and "connection" should be understood broadly, which can be mechanical connection or electrical connection, or the communication between the two elements, or direct connection, "up", "down", "left", "right" and the like are only used to represent the relative positional relationship, when the absolute position of the described object changes, the relative positional relationship may change;
