Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.
[0019] Please refer to Figures 1-4, the present utility model provides a technical solution: a protection pipe for a railway signal box, which includes a left half pipe 1 and a right half pipe 2. The upper and lower ends of the left half pipe 1 and the right half pipe 2 are respectively provided with a left outer edge 3 and a right outer edge 4. A pair of left sockets and a pair of right sockets are respectively opened inside the left outer edge 3 and the right outer edge 4. A fixing pin 14 is respectively inserted inside a pair of the left sockets and the right sockets. A groove is opened inside one end of the fixing pin 14, and a fixing mechanism is arranged inside the groove. A pair of baffles 10 are arranged at the other end of the fixing pin 14, and the pair of baffles 10 are in contact with the right outer edge 4; the structures of the left half pipe 1 and the right half pipe 2 are the same. When in use, they are buckled together from both sides of the cable and fixed by the fixing pin 14. The fixing pin 14 is a whole column, which is convenient to carry. When installing, the baffle 10 needs to be lifted and the plastic retaining ring 12 needs to be removed for use.
[0020] Further, the fixing mechanism includes a slide bar 7 slidably inserted inside the groove. The two ends of the slide bar 7 are respectively connected with a round cap 8 and a spring 9. One end of the spring 9 is connected with the side wall of the groove. First chutes are obliquely opened inside the two side walls of the groove. Second chutes are obliquely opened inside the inner walls of the two sides of the left socket. A positioning pin 5 is respectively slidably inserted inside a pair of the first chutes and the second chutes. One ends of a pair of the positioning pins 5 are respectively connected with an elastic metal sheet 6. One ends of a pair of the elastic metal sheets 6 are fixedly connected with the side wall of the slide bar 7; the elastic metal sheet 6 is a kind of metal sheet that is easy to bend and has high toughness. It belongs to an existing kind of metal sheet and can bend and slide inside the first chute and the groove for pushing and pulling the positioning pin 5.
[0021] Further, a pair of placement grooves 11 are opened inside the other end of the fixing pin 14. A pair of the baffles 10 are respectively hinged inside the inner walls of a pair of the placement grooves 11. The side walls of a pair of the baffles 10 are respectively in contact with the side walls of a pair of the placement grooves 11.
[0022] Further, a plastic retaining ring 12 is sleeved on the outer wall of the slide bar 7 and located outside the fixing pin 14. The plastic retaining ring 12 is provided with an opening 13.
[0023] Through those skilled in the art, the components in this case are connected in sequence. For the specific connection and operation sequence, reference should be made to the following working principle. The detailed connection means are well-known techniques in the art. The following mainly introduces the working principle and process.
[0024] Embodiment: When in use, buckle the left half tube 1 and the right half tube 2 on the outside of the cable, align the left outer edge 3 and the right outer edge 4, then lift the baffle 10 in the placement groove 11, then insert the fixing pin 14 into the left socket and the right socket in the left outer edge 3 and the right outer edge 4, and finally pull out the plastic retaining ring 12 on the fixing pin 14 to complete the fixation. When the plastic retaining ring 12 is pulled out, the spring 9 pulls the slide bar 7 to move inward to the groove. During the movement, the slide bar 7 will push the positioning pin 5 in the first chute through the elastic metal sheet 6, so that one end of the positioning pin 5 is inserted into the first chute in the left outer edge 3 to complete the fixation. When disassembly is required, pull the round cap 8 and pull the slide bar 7 to the outside of the groove. The slide bar 7 pulls the positioning pin 5 through the elastic metal sheet 6, so that one end of the positioning pin 5 leaves the first chute in the left outer edge 3, and then pull out the fixing pin 14. The design is very convenient for disassembly and assembly, does not require tools, and is lighter in weight than bolts and nuts.
