Description

Technical Field

[0001] The utility model relates to the technical field of video optical terminal equipment, in particular to a high temperature resistant video optical terminal equipment. Background Art

[0002] During the use of existing video optical terminals, most of their connection ports are exposed. Once the terminals are not connected for a long time, dust or even moisture will enter the inside of the connection terminals of the video optical terminals, causing corrosion, resulting in the inability to complete signal transmission later.

[0003] In the prior art, a utility model patent with authorization announcement number CN214481020U discloses a moisture-proof and high-temperature resistant video optical terminal. By movably sleeved a movable baffle on the inner side of a connecting base and then fixing a sealing strip on the rear end of the movable baffle, the movable baffle can better seal the connecting port to prevent dust and moisture from entering when the end is not connected, thereby solving the problem of insensitive connection caused by the connection port being easily corroded by moisture and dust when the existing device is used.

[0004] However, the above patent still has the following problems when in use: the number of connection ports on the video optical terminal is generally multiple, and not all of them are necessarily connected to the cable connectors during a single use, while the above patent uses an integral movable baffle to cover all connection terminals, which makes it easy for the video optical terminal to be in use and the movable baffle is in an open state, and some connection ports will be exposed to the outside, which still easily leads to the risk of connection failure due to moisture and dust corrosion of the connection ports. Therefore, a high temperature resistant video optical terminal is proposed. Utility Model Content

[0019] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0020] The utility model provides Figure 1-3 A high temperature resistant video optical terminal shown in the figure comprises a video optical terminal body 100, a mounting frame 200 is fixedly mounted at the connection port of the video optical terminal body 100, a rotatable shielding cover 300 is arranged at the front end of the mounting frame 200, the mounting frame 200 is a hollow structure, and the mounting frame 200 is fixedly mounted to the connection port position on the front of the video optical terminal body 100 to surround the connection port, and then the shielding cover 300 is rotatably mounted on the mounting frame 200, so that the shielding cover 300 is in contact with the front of the mounting frame 200 in the initial state, so as to achieve shielding protection and dustproof effect on the connection port on the video optical terminal body 100, and in order to enhance the sealing performance, a sealing ring can be configured on the mounting frame 200 to contact the back of the shielding cover 300;

[0021] It should be noted that the shielding cover 300 includes a plurality of middle covers 302 and two side covers 301, the plurality of middle covers 302 are arranged in sequence, the two side covers 301 are symmetrically arranged on both sides of the plurality of middle covers 302, the tops of the plurality of middle covers 302 are movably plugged with connecting shafts 303, and the tops of the side covers 301 are movably plugged with the outer walls of the connecting shafts 303, and the two ends of the connecting shafts 303 are movably connected with the tops of the mounting frame 200, respectively. Since the shielding cover 300 is transformed from an integrated structure into a split structure consisting of two side covers 301 and a plurality of middle covers 302 arranged between the two side covers 301, the shielding cover 300 can be adjusted according to the specific position on the video optical terminal body 100. By using the connection port, the middle cover 302 or the side cover 301 at the corresponding position is rotated open, so that the cable connector can be smoothly inserted into the connection port, thereby avoiding that other unused connection ports are directly exposed to the outside. Compared with the prior art that uses an integrated cover structure to shield and dustproof multiple connection ports, the protection effect is higher and the adaptability is higher; among them, in order to further improve the convenience of using the shielding cover 300, a torsion spring structure can be added between the side cover 301 and the middle cover 302 and the connecting shaft 303, so that the side cover 301 or the middle cover 302 can be rotated upward and the elastic reset force provided by the torsion spring structure can be used, so that the side cover 301 or the middle cover 302 can have a rotational reset power.

[0022] Furthermore, a cross groove 305 is provided in the middle of the middle cover plate 302, and a limit rod 307 is movably connected in the cross groove 305, and the limit rod 307 can move axially along the cross groove 305. A limit ring 308 is movably connected to the inner cavity of the cross groove 305, and the inner side of the limit ring 308 is fixedly connected to the outer wall of the limit rod 307, and a return spring 309 is fixedly connected between the limit ring 308 and the inner wall of the cross groove 305. Through the configuration of the limit rod 307, the limit ring 308 and the return spring 309 in the cross groove 305 in the middle cover plate 302, the limit rod 307 can be moved in the cross groove 305. The cross groove 305 can elastically extend and retract, so that when there is an external thrust, one end of the limit rod 307 can extend from the side wall of the middle cover 302, and after the external thrust is removed, the end of the limit rod 307 can automatically retract into the cross groove 305 for storage, so that the locking or unlocking between adjacent middle covers 302 can be achieved, so as to achieve the purpose of fixing multiple middle covers 302 and realizing synchronous rotation. In this way, when the corresponding connection ports of the middle covers 302 need to be connected with cable connectors, the rotation drive of multiple middle covers 302 can be completed in one step, and the operation is more convenient and efficient.

[0023] Moreover, one of the side cover plates 301 is provided with a positioning slot 306 on the side facing the middle cover plate 302, the inner side of the positioning slot 306 is connected to the cross slot 305, and the inner diameter of the positioning slot 306 is greater than or equal to the outer diameter of the limiting plug rod 307, so that when one end of the limiting plug rod 307 on the middle cover plate 302 at the sidemost position is extended, it can be inserted into the positioning slot 306, thereby locking the corresponding side cover plate 301; an inner screw hole is provided in the middle part of the other side cover plate 301, and the side cover plate 301 is threadedly connected with a knob screw 304 through the inner screw hole, and the length of the knob screw 304 is greater than the front width of the side cover plate 301. 306, the limit rod 307 and the knob screw 304 are located on the same horizontal line, and the knob screw 304 is telescopically moved while rotating on the side cover 301, so that one end of the knob screw 304 can be inserted into the cross groove 305 of the middle cover 302 at the corresponding position, so as to provide a thrust for the internal limit rod 307, so that the middle cover 302 and the side cover 301 can be synchronously locked or unlocked, which is convenient for opening the entire shielding cover 300 in one step when all the connection ports need to be used, and when a single operation is required, it is only necessary to rotate the knob screw 304, which is more functional and more adaptable to use.

[0024] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent substitutions for some of the technical features therein.
