In addition, some aspects disclosed in the present invention can be used alone or in any appropriate combination with other aspects disclosed in the present invention.

[0024] Example 1

[0025] like Figure 1-4 FIG. 1 is a first embodiment of the present invention, which provides a wall-mounted optical cable terminal box for railway use, comprising:

[0026] The main unit 1 includes a fixing plate 101. A mounting bracket 102 is provided on the front of the fixing plate 101. There are two mounting brackets 102. A rubber pad 103 is fixedly connected to the adjacent side of the two mounting brackets 102. A terminal box body 104 is detachably connected between the two mounting brackets 102. The side of the rubber pad 103 away from the mounting bracket 102 is in close contact with the surface of the terminal box body 104.

[0027] The fixing unit 2 includes a fixing pin 201, which is located on the right side of the front of the fixing plate 101 and is fixedly connected to the fixing plate 101. A movable pin 202 is slidably connected to the left side of the front of the fixing plate 101. Both sides of the top of the upper mounting frame 102 are fixedly connected with fixing rings 203. The ends of the fixing pin 201 and the movable pin 202 that are close to each other extend to the inner cavities of the two fixing rings 203 respectively and engage with their inner cavities.

[0028] like Figure 1-4 As shown, the fixing plate 101, the mounting frame 102 and the rubber pad 103 cooperate to support the terminal box body 104 so that the terminal box body 104 can be wall-mounted, thereby reducing the floor space. The fixed column 201, the movable column 202 and the fixing ring 203 cooperate to facilitate the installation of the mounting frame 102. At the same time, under the action of the fixing unit 2, the terminal box body 104 can be quickly installed on the wall or removed from the wall by simply pulling the pull rope 207. Therefore, the purpose of rapid installation and disassembly can be achieved, further improving the maintenance efficiency of the terminal box body 104. At the same time, since the cost of each structure in the main unit 1 and the fixing unit 2 is relatively low, it is easy to promote and use.

[0029] Example 2

[0030] Reference Figure 2 and 3 , which is the second embodiment of the present utility model, and this embodiment is based on the previous embodiment.

[0031] In this embodiment, the inner cavity of the lower mounting frame 102 is threadedly connected to a threaded rod 105 , the top of the threaded rod 105 passes through the lower mounting frame 102 and is movably connected to the bottom of the upper mounting frame 102 via a bearing.

[0032] Positioning grooves 106 are provided on both sides of the top of the lower mounting frame 102, and positioning plates 107 are fixedly connected on both sides of the bottom of the upper mounting frame 102. The bottom of the positioning plate 107 extends to the inner cavity of the positioning groove 106 and is slidably connected to the inner cavity of the positioning groove 106.

[0033] Both sides of the fixing plate 101 are fixedly connected with fixing plates 108 , and the inner cavity of the fixing plates 108 is detachably connected with mounting bolts 109 .

[0034] like Figure 2 and 3As shown, by rotating the threaded rod 105, the distance between the two mounting brackets 102 can be adjusted so that the terminal box body 104 can be clamped and fixed. The positioning groove 106 and the positioning plate 107 cooperate to limit the lower end mounting bracket 102 to prevent its angle from deflecting. The fixing piece 108 and the mounting bolt 109 cooperate to facilitate the installation of the fixing plate 101 on the wall.

[0035] Example 3

[0036] Reference Figure 2 and 4 , which is the third embodiment of the present utility model, is based on the first two embodiments.

[0037] In this embodiment, a hollow column 204 is fixedly connected to the left side of the front of the fixed plate 101, a movable piece 205 is slidably connected to the inner cavity of the hollow column 204, a connecting column 206 is fixedly connected to the right side of the movable piece 205, and the right end of the connecting column 206 passes through the outside of the hollow column 204 and is fixedly connected to the movable plug column 202.

[0038] A pull rope 207 is fixedly connected to the left side of the movable piece 205, and the left end of the pull rope 207 passes through the outside of the hollow column 204. A compression spring 208 is provided on the surface of the pull rope 207 and located in the inner cavity of the hollow column 204. One end of the compression spring 208 is fixedly connected to the inner wall of the hollow column 204, and the other end of the compression spring 208 is fixedly connected to the movable piece 205.

[0039] like Figure 2 and 4 As shown, by pulling the pull rope 207, the movable piece 205 can be driven to move inside the hollow column 204. When the movable piece 205 moves, it can squeeze the compression spring 208 and cause the compression spring 208 to deform. When the movable piece 205 moves, it can cooperate with the connecting column 206 to drive the movable plug column 202 to move, so that the movable plug column 202 is moved out from the inside of the left fixed ring 203. At this time, the mounting bracket 102 can be removed to inspect the terminal box body 104.

[0040] When in use, when the terminal box body 104 needs to be disassembled and repaired, first pull the pull rope 207 downwards. By pulling the pull rope 207, the movable piece 205 can be driven to move inside the hollow column 204. When the movable piece 205 moves, it can squeeze the compression spring 208 and cause the compression spring 208 to deform. While the movable piece 205 moves, it can cooperate with the connecting column 206 to drive the movable plug post 202 to move, so that the movable plug post 202 is moved out from the inside of the left fixing ring 203. At this time, the mounting bracket 102 can be removed. After removal, rotate the threaded rod 105 to adjust the height of the lower end mounting bracket 102 and move it downward. At this time, the distance between the two mounting brackets 102 increases, and the clamping effect on the terminal box body 104 disappears, and the terminal box body 104 can be removed.

[0041] The standard parts used in this application document can all be purchased from the market, and can be customized according to the description in the specification and drawings. The specific connection methods of each part adopt conventional means such as mature bolts, rivets, welding, etc. in the existing technology. The machinery, parts and equipment all adopt conventional models in the existing technology. The control method is automatic control through a controller. The control circuit of the controller can be implemented by simple programming by technicians in this field, which is common knowledge in this field. In addition, this application is mainly used to protect mechanical devices, so this application no longer explains the control method and circuit connection in detail.

[0042] While the present invention has been described above with reference to preferred embodiments, this is not intended to limit the present invention. Persons skilled in the art will readily appreciate that various modifications and variations may be made without departing from the spirit and scope of the present invention. Therefore, the scope of protection of the present invention shall be determined by the claims.
