They are mainly used in process control, manufacturing, building automation, and other fields to enable interconnection and communication between intelligent devices in the field.

[0003] As a key carrier for communication between industrial automation equipment, fieldbus cables are exposed to complex environments such as mechanical stress, chemical corrosion, extreme temperatures and electromagnetic interference for a long time. Existing protection technologies have the problem of weak resistance to mechanical damage, while traditional sheath materials (such as rubber and PVC) are prone to aging and cracking, and cannot withstand equipment dragging or impact from sharp objects. In order to address the above problems and defects, a fieldbus cable protection mechanism is urgently needed. Utility Model Content

[0004] The technical problem to be solved by this utility model is to provide a fieldbus cable protection mechanism to address the problem that existing fieldbus cables, as key carriers for communication between industrial automation equipment, are exposed to complex environments such as mechanical stress, chemical corrosion, extreme temperatures and electromagnetic interference for a long time. Existing protection technologies have the problem of weak resistance to mechanical damage, while traditional sheath materials (such as rubber and PVC) are prone to aging and cracking, and are difficult to withstand the limitations of equipment dragging or impact from sharp objects.

[0005] To solve the above-mentioned technical problems, this utility model provides the following technical solution:

[0006] A fieldbus cable protection mechanism includes: a bus cable body, and a fixing component, a protection component, and an extension component mounted on the bus cable body; the fixing component includes a base mounted on the bottom of the bus cable body, a top cover abutting the top of the bus cable body, a square groove formed at the bottom of the top cover, a circular groove formed on the inner wall of the square groove, a spring fixedly mounted on the inner wall of the circular groove, a connecting block fixedly mounted on the end of the spring away from the circular groove, a locking block fixedly mounted on the side of the connecting block away from the spring, a fixing pin engaging the outer wall of the locking block, a rotating shaft rotatably connected to the top of the top cover, a connecting rope fixedly connected to the outer wall of the rotating shaft, and a connecting rope fixedly connected to the connecting block at the end of the connecting rope away from the rotating shaft.

[0007] Preferably, the protective component includes a positioning seat, a limiting rod is fixedly mounted on the top of the positioning seat, a positioning cover is slidably connected to the outer wall of the limiting rod, a first protective ring is fixedly mounted on the outer wall of the positioning cover, a second protective ring is fixedly mounted on the side of the top cover near the positioning cover, and a sliding rod is fixedly mounted on the end of the second protective ring near the first protective ring, with the outer wall of the sliding rod slidably connected to the first protective ring.

[0008] Preferably, the extension assembly includes a positioning shaft mounted on the outer wall of the positioning cover. The outer wall of the positioning shaft has an annular groove. A rotating ring is rotatably connected to the outer wall of the annular groove. A screw is rotatably connected to the inner wall of the rotating ring. A fixing shaft is fixedly mounted at the end of the screw away from the positioning shaft. The end of the fixing shaft away from the screw is fixedly connected to the top cover.

[0009] Preferably, positioning plates are fixedly mounted on both sides of the top cover, and a limiting shaft is fixedly mounted on the bottom of the base, with the outer wall of the limiting shaft slidably connected to the positioning plates.

[0010] Preferably, a protective pad is fixedly fitted to the bottom of the top cover. The protective pad is a rubber pad, and the outer wall of the protective pad abuts against the bus cable body.

[0011] Preferably, the number of springs, connecting blocks, locking blocks, fixing pins and connecting ropes is two sets, and the two sets of springs, connecting blocks, locking blocks, fixing pins and connecting ropes are symmetrically distributed on both sides of the rotating shaft.

[0012] Compared with the prior art, this utility model has at least the following beneficial effects:

[0013] 1. In the above solution, the bus cable body is placed on top of the base, and then the top cover is pushed towards the base. At this time, the fixing pin moves in the square groove. When the locking block is squeezed by the fixing pin, the locking block moves deeper into the round groove. When the fixing pin is fully inserted into the square groove, the locking block is no longer squeezed. The spring pushes the connecting block and the locking block towards the fixing pin until they are locked together, thereby connecting the base and the top cover and fixing the bus cable body, thus protecting the bus cable body. When the bus cable body needs to be replaced or maintained, it is only necessary to rotate the shaft. The rotation of the shaft will wrap the connecting rope around the outer wall of the shaft. The connecting rope will pull the connecting block and the locking block away from the fixing pin, so that the locking block and the fixing pin are separated. The top cover can then be separated from the base, and the bus cable body can be taken out. This improves the convenience of protecting the bus cable body and ensures the service life of the bus cable body.

[0014] 2. In the above scheme, by setting up protective ring one and protective ring two, it is beneficial to protect the outer wall of the bus cable body and prevent the outer wall of the bus cable body from being worn. By setting up a positioning shaft, a rotating ring, a screw and a fixed shaft, by rotating the rotating ring, the screw will be rotated, thereby separating the position of the positioning shaft from the screw and the fixed shaft, thereby adjusting the length of the device, which is beneficial to protect the bus cable body of different lengths.

Detailed Implementation

[0027] The fieldbus cable protection mechanism provided by this utility model will be described in detail below with reference to the accompanying drawings and specific embodiments. It should be noted that, to make the embodiments more detailed, the following embodiments are listed as best and preferred embodiments, and other alternative methods may be used by those skilled in the art; moreover, the accompanying drawings are only for more specific description of the embodiments and are not intended to specifically limit this utility model.

[0028] like Figure 1 , Figure 3 and Figure 4 As shown, an embodiment of this utility model provides a fieldbus cable protection mechanism, including: a bus cable body 1, and a fixing component 2, a protection component 3, and an extension component 4 installed on the bus cable body 1; the fixing component 2 includes a base 201 installed at the bottom of the bus cable body 1, a top cover 202 abutting the top of the bus cable body 1, a square groove 210 formed at the bottom of the top cover 202, a circular groove 203 formed on the inner wall of the square groove 210, a spring 204 providing elastic force fixedly mounted on the inner wall of the circular groove 203, a connecting block 205 fixedly mounted on the end of the spring 204 away from the circular groove 203, a locking block 206 fixedly mounted on the side of the connecting block 205 away from the spring 204, and a fixing pin 207 engaging the outer wall of the locking block 206. A rotating shaft 208 is rotatably connected to the top of the top cover 202. A connecting rope 209 is fixedly connected to the outer wall of the rotating shaft 208. The end of the connecting rope 209 away from the rotating shaft 208 is fixedly connected to the connecting block 205. There are two sets of springs 204, connecting blocks 205, locking blocks 206, fixing pins 207 and connecting ropes 209. The two sets of springs 204, connecting blocks 205, locking blocks 206, fixing pins 207 and connecting ropes 209 are symmetrically distributed on both sides of the rotating shaft 208. By limiting the number and position of springs 204, connecting blocks 205, locking blocks 206, fixing pins 207 and connecting ropes 209, it is beneficial to improve the firmness and stability of the connection between the base 201 and the top cover 202, thereby ensuring the protection effect on the bus cable body 1.

[0029] like Figure 2 and Figure 3As shown, the protective component 3 includes a positioning seat 301. A limiting rod 302 is fixedly mounted on the top of the positioning seat 301. A positioning cover 303 is slidably connected to the outer wall of the limiting rod 302. A protective ring 304 is fixedly mounted on the outer wall of the positioning cover 303. A protective ring 305 is fixedly mounted on the side of the top cover 202 near the positioning cover 303. A sliding rod 306 is fixedly mounted on the end of the protective ring 305 near the protective ring 304. The outer wall of the sliding rod 306 is slidably connected to the protective ring 304. By setting the positioning seat 301, the limiting rod 302, the positioning cover 303, the protective ring 304, the protective ring 305, and the sliding rod 306, it is beneficial to protect the bus cable body 1 through the protective ring 304 and the protective ring 305, thereby preventing the outer wall of the bus cable body 1 from being worn and thus improving the service life of the bus cable body 1.

[0030] like Figure 3 and Figure 5 As shown, the extension component 4 includes a positioning shaft 401 mounted on the outer wall of the positioning cover 303. An annular groove 402 is formed on the outer wall of the positioning shaft 401. A rotating ring 403 is rotatably connected to the outer wall of the annular groove 402. A screw 404 is rotatably connected to the inner wall of the rotating ring 403. A fixed shaft 405 is fixedly mounted on the end of the screw 404 away from the positioning shaft 401. The end of the fixed shaft 405 away from the screw 404 is fixedly connected to the top cover 202. By setting the extension component 4, rotating the rotating ring 403 causes the rotating ring 403 to be threadedly connected to the screw 404, thereby causing the screw 404 to slide inside the positioning shaft 401. This, in turn, causes the positioning shaft 401 and the fixed shaft 405 to adjust their lengths, thereby causing the device to adjust its length according to the actual length of the bus cable body 1, thus achieving its protective effect.

[0031] like Figure 2 and Figure 4 As shown, positioning plates 211 are fixedly mounted on both sides of the top cover 202, and a limiting shaft 212 is fixedly mounted on the bottom of the base 201. The outer wall of the limiting shaft 212 is slidably connected to the positioning plates 211. By setting the positioning plates 211 and the limiting shaft 212, it is beneficial to limit the position of the base 201 and the top cover 202, thereby facilitating the disassembly and assembly of the fixing component 2.

[0032] like Figure 2 and Figure 4 As shown, a protective pad 213 is fixedly installed at the bottom of the top cover 202. The protective pad 213 is a rubber pad, and the outer wall of the protective pad 213 abuts against the bus cable body 1. By setting the protective pad 213, it is beneficial to reduce the wear on the outer wall of the bus cable body 1 by the protective pad 213 abutting against the bus cable body 1 when the base 201, the top cover 202 and the bus cable body 1 are fixed.

[0033] The technical solution provided by this utility model, during operation, involves placing the bus cable body 1 on top of the base 201, and then pushing the top cover 202 towards the base 201. At this time, the fixing pin 207 moves within the square groove 210. When the locking block 206 is pressed by the fixing pin 207, it moves deeper into the circular groove 203. When the fixing pin 207 is fully inserted into the square groove 210, the locking block 206 is no longer pressed, and the connecting block 205 and the locking block 206 are pushed towards the fixing pin 207 by the spring 204 until they are locked together, thereby securing the base 201 and the top cover 201. 02 connects and fixes the bus cable body 1, thus protecting the bus cable body 1. When the bus cable body 1 needs to be replaced or maintained, simply rotate the shaft 208. The rotation of the shaft 208 will cause the connecting rope 209 to be wrapped around the outer wall of the shaft 208. The connecting rope 209 will pull the connecting block 205 and the locking block 206 to the side away from the fixing pin 207, so that the locking block 206 and the fixing pin 207 can be separated. Then the top cover 202 can be separated from the base 201 and the bus cable body 1 can be taken out, which will improve the convenience of protecting the bus cable body 1.

[0034] By setting up a positioning seat 301, a limiting rod 302, a positioning cover 303, a first protective ring 304, a second protective ring 305, and a sliding rod 306, it is beneficial to protect the bus cable body 1 through the first protective ring 304 and the second protective ring 305, thereby preventing the outer wall of the bus cable body 1 from being worn and thus improving the service life of the bus cable body 1.

[0035] By setting the extension component 4, the rotating ring 403 is threadedly connected to the screw 404, thereby causing the screw 404 to slide inside the positioning shaft 401, which in turn causes the positioning shaft 401 and the fixed shaft 405 to adjust in length, and thus causes the device to adjust in length. This is beneficial to adjust the length of the device according to the actual length of the bus cable body 1, thereby achieving its protective effect.

[0036] The above description is only a preferred embodiment of the present utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the principle of the present utility model, and these improvements and modifications should also be considered within the protection scope of the present utility model.
