Description

Technical Field

[0001] The utility model relates to the technical field of communication engineering, in particular to a dustproof optical fiber exchange cabinet for communication engineering. Background Art

[0002] Communication engineering, also known as telecommunication engineering, formerly known as long-distance communication engineering and weak-current engineering, is an important branch of electronic engineering, a sub-major of electronic information, and also one of the basic disciplines. This discipline focuses on the principles and applications of information transmission and signal processing in the communication process. Fiber optic switch cabinets are required when installing fiber optic switches in communication engineering.

[0003] At present, a Chinese patent with announcement number CN213547734U discloses a dustproof fiber optic switch cabinet, which belongs to the field of information technology. The dustproof fiber optic switch cabinet includes a fiber optic switch cabinet body, a cabinet door, a partition board, and a dust removal component. One side of the fiber optic switch cabinet body is hingedly connected to the cabinet door, and a heat dissipation hole is provided on the side away from the cabinet door. The heat dissipation holes are evenly distributed on the side of the fiber optic switch cabinet body. The partition board is slidably connected to the middle of the fiber optic switch cabinet body. The dust removal component is arranged near the heat dissipation hole and is located inside the fiber optic switch cabinet body. A through groove is opened on the partition board corresponding to the position of the dust removal component. The cabinet is electrically connected through an anode plate and a cathode plate to perform electrostatic adsorption dust removal. The dust removal efficiency is high, and dust is automatically adsorbed to prevent dust from entering the switch during operation, thereby extending the service life of the switch.

[0004] Most existing methods for preventing dust from entering fiber optic switch cabinets used in communication projects are to filter dust in the air pumped by the fan through a filter plate when the fan dissipates heat from the fiber optic switch inside the fiber optic switch cabinet, so that the fiber optic switch cabinet has a dust-proof effect. However, the dust-proof filter plates inside most fiber optic switch cabinets are not convenient to remove and replace, and the fans are mostly fixed to the inside of the fiber optic switch cabinet with multiple bolts, which makes it inconvenient to remove and maintain the fans.

[0006] The utility model is implemented as follows: a dustproof optical fiber exchange cabinet for communication engineering, comprising an optical fiber exchange cabinet body, a cabinet door, a lock and a plurality of mounting plates, both sides of the bottom of the optical fiber exchange cabinet body are fixedly connected with slide rails, a filtering mechanism is arranged at the bottom of the optical fiber exchange cabinet body, and a limited position frame is arranged at the bottom of the filtering mechanism;

[0015] Compared with the prior art, the beneficial effects of the utility model are:

It should be understood that the specific embodiments described here are only used to explain the utility model and are not used to limit the utility model.

In addition, in the description of the present invention, "multiple" means two or more, unless otherwise clearly and specifically defined.

[0028] See also Figure 1-8 The utility model provides a technical solution: a dustproof optical fiber exchange cabinet for communication engineering, comprising an optical fiber exchange cabinet body 1, a cabinet door 2, a lock 5 and a plurality of mounting plates 6, both sides of the bottom of the optical fiber exchange cabinet body 1 are fixedly connected with slide rails 9, a filter mechanism 8 is arranged at the bottom of the optical fiber exchange cabinet body 1, and a limit position frame 4 is arranged at the bottom of the filter mechanism 8;

[0029] The filtering mechanism 8 includes two fans 801, two through holes 802, a filter plate 803 and a fixed plate 804. The through holes 802 are opened inside the fixed plate 804. The surface of the fan 801 is fixedly connected to the inner wall of the through holes 802. The top of the filter plate 803 contacts the bottom of the fixed plate 804.

[0030] In this embodiment: when the optical fiber switch is installed inside the optical fiber switch cabinet body 1 and used, the fan 801 is controlled to work, and the fan 801 can work to suck air into the filter plate 803 for filtering and then discharge it into the optical fiber switch cabinet body 1 to cool the optical fiber switch inside the optical fiber switch cabinet body 1, so that the optical fiber switch cabinet body 1 has a dust-proof effect. When the fan 801 needs to be maintained and the filter plate 803 needs to be replaced, it is only necessary to twist the two first limit buttons 15 and the two second limit buttons 17 to disengage from the slide rail 9, and the fan 801 can be pulled out for maintenance. The filter plate 803 can be pulled out for protection and replacement, thereby avoiding the problem that most existing methods for preventing dust from affecting the fiber optic switch cabinets used in communication projects are as follows: when the fan 801 dissipates heat for the fiber optic switch inside the fiber optic switch cabinet, the filter plate 803 is used to filter the dust in the air pumped by the fan 801, so that the fiber optic switch cabinet has a dust-proof effect. However, the filter plates 803 for dust-proof filtration inside most fiber optic switch cabinets are not convenient to be removed and replaced, and the fan 801 is mostly fixed to the inside of the fiber optic switch cabinet with multiple bolts, which makes it inconvenient to dismantle the fan 801 for maintenance.

[0032] In this embodiment, the bottom of the filter plate 803 is in contact with the top of the stopper 13 , so that the stopper 13 can limit the filter plate 803 , thereby achieving the effect of limiting the filter plate 803 .

[0033] As a technical optimization solution of the present invention, an air inlet groove 7 is provided at the bottom of the inner wall of the fiber optic switch cabinet body 1 , and the fixing plate 804 is movably connected between opposite sides of the two slide rails 9 .

[0034] In this embodiment, the air filtered by the filter plate 803 will enter the interior of the optical fiber exchange cabinet body 1 through the air inlet groove 7, thereby achieving the effect of facilitating the air to enter the interior of the optical fiber exchange cabinet body 1.

[0035] As a technical optimization solution of the utility model, both sides of the front side of the fixed plate 804 are fixedly connected with a first limit block 11, the front side of the first limit block 11 is provided with a first limit button 15, and the rear side of the first limit button 15 passes through the first limit block 11 and is connected with the internal thread of the slide rail 9.

[0036] In this embodiment: by passing the first limit button 15 through the first limit block 11, and then rotating the first limit button 15 to be connected with the internal thread of the slide rail 9, the first limit button 15 can limit the fixing plate 804, thereby achieving the effect of limiting the fixing plate 804.

[0037] As a technical optimization solution of the utility model, a slide groove 14 is opened inside the slide rail 9, and slide bars 16 are fixedly connected to both sides of the limit frame 4. The surface of the slide bar 16 is slidably connected to the inside of the slide groove 14.

[0038] In this embodiment: by inserting the slide bar 16 into the slide groove 14, the limit frame 4 can be connected to the slide rail 9, and through the internal sliding connection of the slide bar 16 and the slide groove 14, the limit frame 4 can be easily pulled, thereby achieving the effect of facilitating the connection of the limit frame 4 to the slide rail 9.

[0039] As a technical optimization solution of the utility model, the second limit blocks 12 are fixedly connected to both sides of the limit frame 4, and a second limit button 17 is provided at the bottom of the second limit block 12. The top of the second limit button 17 passes through the second limit block 12 and is connected to the internal thread of the slide rail 9.

[0040] In this embodiment, the second limiting button 17 passes through the second limiting block 12 and is connected to the inner thread of the slide rail 9, so that the limiting frame 4 can be limited, thereby achieving the effect of limiting the limiting frame 4.

[0041] As a technical optimization solution of the present invention, the front sides of the fixing plate 804 and the limiting frame 4 are both fixedly connected with a handle 10 .

[0042] In this embodiment, by holding the handle 10 , the fixing plate 804 and the limiting frame 4 can be conveniently pulled, thereby achieving the effect of conveniently pulling the fixing plate 804 and the limiting frame 4 .

[0043] As a technical optimization solution of the present utility model, an exhaust port 3 is provided on the top of the fiber optic switch cabinet body 1 .

[0044] In this embodiment, the air with high temperature inside the fiber optic switch cabinet body 1 will be discharged from the fiber optic switch cabinet body 1 through the exhaust port 3, so as to achieve the effect of conveniently discharging the hot air inside the fiber optic switch cabinet body 1.

[0045] Working principle: First, when the optical fiber switch is installed inside the optical fiber switch cabinet body 1 and used, the fan 801 is controlled to work. The fan 801 can work to suck air into the filter plate 803. The filter plate 803 will filter the dust in the air and then enter the optical fiber switch cabinet body 1 through the air inlet slot 7. At this time, the low-temperature air will cool down the optical fiber switch inside the optical fiber switch cabinet body 1, and the heated air will be discharged from the optical fiber switch cabinet body 1 through the exhaust port 3. The fan 801 can continuously work to filter the low-temperature air and blow it into the optical fiber switch cabinet body 1 to continuously cool down the optical fiber switch. While cooling the optical fiber switch installed inside the optical fiber switch cabinet body 1, dust can be prevented from entering the optical fiber switch cabinet body 1, so that the optical fiber switch cabinet body 1 has a dust-proof effect. When the filter plate 803 needs to be replaced, the second limit button 17 is turned to disengage the second limit button 17 from the slide rail 9. At this time, the limit frame 4 can be pulled forward from the bottom of the optical fiber switch cabinet body 1, and the filter plate 803 can be taken out and replaced. When it is necessary to maintain the fan 801, the first limit button 15 is turned to disengage the first limit button 15 from the slide rail 9, and the fixing plate 804 can be pulled forward from the bottom of the fiber optic switch cabinet body 1, so that the fan 801 can be easily maintained. By twisting the two first limit buttons 15 and the two second limit buttons 17 to disengage from the slide rail 9, the fan 801 can be maintained and the filter plate 803 can be replaced, avoiding the existing method of dustproofing the fiber optic switch cabinet used in most communication projects, that is, when the fan 801 is in contact with the fiber optic switch cabinet, the filter plate 803 can be replaced. When the fiber optic switch inside the cabinet is dissipating heat, the dust in the air sucked by the fan 801 is filtered through the filter plate 803, so that the fiber optic switch cabinet has a dust-proof effect. However, the dust-proof filter plates 803 inside most fiber optic switch cabinets are not convenient to remove and replace, and the fan 801 is mostly fixed to the inside of the fiber optic switch cabinet with multiple bolts, which makes it inconvenient to dismantle and maintain the fan 801. It should be noted that the fiber optic switch cabinet body 1 and the lock 5 are both existing mature technologies that have been published and will not be elaborated here.

[0046] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
