[0002] Railway communication boxes are important equipment in railway communication and signaling systems, mainly used to realize train operation control, data transmission and equipment protection functions. They usually install a variety of communication devices inside, and the bottom of the communication box has multiple interfaces for connecting various communication lines and devices. However, after the cables are connected to the communication devices, in the complex operating environment of railways, the communication cables are easily affected by external factors, such as external impacts and collisions, which can cause them to loosen and fall off. In addition, the interfaces lack effective protection measures when not in use, and impurities from the external environment can easily enter, which needs to be improved. Utility Model Content

Detailed Implementation
[0017] The technical solution of this utility model will be clearly and completely described below with reference to the accompanying drawings. In addition, the forms of the various structures described in the following embodiments are merely illustrative. The interface protection device for railway communication involved in this utility model is not limited to the structures described in the following embodiments. All other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.
[0018] Example 1: like Figure 1-5As shown, an interface protection device for railway communication includes a communication box 1. A door 2 is installed on the front of the communication box 1. A communication equipment mounting bracket 3 is fixedly installed inside the communication box 1. The mounting bracket 3 facilitates the secure installation of various communication devices inside the communication box 1. The bottom of the communication box 1 has multiple interfaces 4 and multiple protective structures 5. Each protective structure 5 includes a fixing cover 51, a first L-shaped protective cover 56, and a second L-shaped protective cover 57. The top of the fixing cover 51 is fixedly installed... At the bottom of communication box 1, both L-shaped protective cover 56 and L-shaped protective cover 57 are located in front of fixed cover 51. A positioning block 55 is slidably connected inside fixed cover 51. The center of the back of L-shaped protective cover 56 is fixedly mounted on the front of positioning block 55. Anti-slip pads 58 are fixedly connected to the inner walls of both L-shaped protective cover 56 and L-shaped protective cover 57. Internal threads are provided at the front ends of the inner walls of both L-shaped protective cover 56 and L-shaped protective cover 57. The top of L-shaped protective cover 56 overlaps the communication box. At the bottom of the communication box 1, the top of the second L-shaped protective cover 57 is fixedly connected to the bottom of the communication box 1. The first L-shaped protective cover 56 is located on the left side below the interface 4, and the second L-shaped protective cover 57 is located on the right side below the interface 4. The fixed cover 51 has a screw 54 inside, and the internal thread of the positioning block 55 is connected to the outer wall of the screw 54. The right end of the screw 54 is rotatably mounted on the right side of the inner wall of the fixed cover 51 through a bearing. The left end of the screw 54 extends to the left side of the fixed cover 51 and is fixedly connected to a knob 53. The left side of the fixed cover 51... A protective cover 52 is provided on the side. An annular mounting groove is provided on the left side of the fixing cover 51. The right side of the fixing cover 51 is threaded into the inside of the annular mounting groove. The outer wall of the knob 53 is located inside the protective cover 52. The protective cover 52 is provided to protect the knob 53. When the knob 53 needs to be used, one side of the protective cover 52 is screwed out from the inside of the annular mounting groove to operate the knob 53. After the operation is completed, the protective cover 52 is screwed back into the annular mounting groove to protect the knob 53.
[0019] In this embodiment, when it is necessary to fix and protect the cable at interface 4, the cable below interface 4 can be placed inside the second L-shaped protective cover 57. Then, by rotating the knob 53 and the screw 54, the positioning block 55 is driven to slide inside the fixing cover 51. At the same time, the positioning block 55 drives the first L-shaped protective cover 56 to move to the right until the first L-shaped protective cover 56 and the second L-shaped protective cover 57 clamp and limit the cable. At this time, the anti-slip pad 58 increases the friction between the cable and the protective cover, which facilitates the protection of the cable.
[0020] Example 2: like Figure 1-5As shown, a protective plug 6 is provided in front of the L-shaped protective cover 56 and the L-shaped protective cover 57. The outer wall of the protective plug 6 is provided with external threads. The outer wall of the protective plug 6 is adapted to the interior between the L-shaped protective cover 56 and the L-shaped protective cover 57. A connecting rope 7 is fixedly connected to the front of the L-shaped protective cover 56. The top end of the connecting rope 7 is fixedly connected to the bottom of the communication box 1.
[0021] In this embodiment, when some interfaces 4 are not needed, the operator first drives the first L-shaped protective cover 56 to move, so that the first L-shaped protective cover 56 approaches the second L-shaped protective cover 57 and closes it. At this time, a protective space is formed between the first L-shaped protective cover 56 and the second L-shaped protective cover 57. Then, the protective plug 6 is rotated and installed into the interior between the first L-shaped protective cover 56 and the second L-shaped protective cover 57 through the external thread on its outer wall, thereby sealing the interface 4 and preventing impurities in the external environment from entering the interface 4. Due to the setting of the connecting rope 7, the protective plug 6 will not be lost at will and will always remain connected to the bottom of the communication box 1.
[0022] In summary, as Figure 1-5 As shown, this interface protection device for railway communication allows operators to secure and protect cables at interface 4 or seal unused interfaces 4 according to actual needs. When securing and protecting cables at interface 4, first place the cable below interface 4 inside the second L-shaped protective cover 57, then screw off the protective cover 52 and turn the knob 53. The knob 53 drives the screw 54 to rotate. Since the positioning block 55 is threaded onto the outer wall of the screw 54, the rotation of the screw 54 drives the positioning block 55 to slide inside the fixed cover 51. As the positioning block 55 slides, it drives the first L-shaped protective cover 56 to move to the right until the first L-shaped protective cover 56 is fully extended. L-shaped protective cover 56 and L-shaped protective cover 57 clamp and limit the cable. At this time, the anti-slip pad 58 increases the friction between the cable and the protective cover, which can better protect the cable and prevent the cable from loosening and falling off. Then, the protective cover 52 is screwed back into the annular mounting groove to protect the knob 53. When some interfaces 4 are not needed, the operator first drives L-shaped protective cover 56 close to L-shaped protective cover 57 and closes it. Then, the protective plug 6 is rotated and installed into the interior between L-shaped protective cover 56 and L-shaped protective cover 57 through the external thread on the outer wall to seal the interface 4 and prevent impurities in the external environment from entering the interior of the interface 4.
