Description

Technical Field

[0001] This utility model relates to the field of DCS control system accessories technology, and in particular to a modular wiring fixing device for a DCS control system. Background Technology

[0002] As a key component of industrial automation, the DCS control system has multiple control modules installed inside its outer casing. These control modules connect to a large number of wires during operation. To ensure stable signal transmission and ease of maintenance in the future, these wires must be bundled and securely fixed.

[0003] In existing technologies, the structure of devices used for fixed wiring is relatively simple, but defects have been exposed in practical applications. The installation height of control modules inside the DCS enclosure varies, while the installation position of the fixed device is preset, lacking the flexibility of height adjustment. This results in the fixed device not being able to accurately correspond to control modules in different positions, causing wiring chaos or uneven cable stress.

[0004] Meanwhile, the number of wires leading out from different control modules varies, resulting in a large variation in the diameter of the wire harness. Most existing fixing clamps are designed with a fixed diameter and cannot adaptively clamp wire harnesses of different thicknesses. When the wire harness is too thin, the clamping is not firm, and when the wire harness is too thick, it cannot be effectively closed, which seriously affects the reliability of the fixing.

[0005] Therefore, this utility model proposes a modular wiring fixing device for a DCS control system to overcome the shortcomings of the prior art. Utility Model Content

[0006] In view of the problems in the existing technology of modular wiring fixing device for DCS control system, such as the inability to flexibly adjust the fixed position to adapt to control modules in different positions in the cabinet, and the single clamping structure that is difficult to adaptively clamp wire harnesses of different thicknesses, this utility model aims to provide a modular wiring fixing device for DCS control system with an improved structure that can effectively solve the above problems.

[0007] This utility model provides a modular wiring fixing device for a DCS control system, including: an outer casing, a support frame, an adjustment mechanism, and a fixing mechanism.

[0008] The adjustment mechanism includes two sliding rails fixedly connected to the inner wall of the outer casing and two sliding blocks fixedly connected to the left and right sides of the support frame. The two sliding blocks are slidably connected to the inner walls of the two sliding rails.

[0009] The fixing mechanism includes a support block fixedly connected to the top of the support frame, two outer clamping rings rotatably connected to the top of the support block, two middle clamping rings slidably connected to the inner walls of the two outer clamping rings, two moving rings slidably connected to the inner walls of the two middle clamping rings, and two contact rings slidably connected to the inner walls of the two moving rings.

[0010] A hollow block is fixedly connected to the top of the left outer clamping ring, and a fixed block is fixedly connected to the top of the right outer clamping ring. A locking block is slidably connected to the inner wall of the fixed block, and the locking block is suitable for sliding and locking onto the inner wall of the hollow block.

[0011] Preferably, the adjustment mechanism further includes two latches, which are rotatably connected to the front side of the support frame.

[0012] Preferably, the outer wall of the sliding rail has multiple fixing grooves.

[0013] Preferably, the outer wall of the sliding block has a slot.

[0014] Preferably, the two latches are adapted to rotate through the fixing groove and enter the inner wall of the groove.

[0015] Preferably, the modular wiring fixing device of the DCS control system also includes a control module.

[0016] Preferably, the control module is installed on the inner wall of the outer casing.

[0017] Preferably, the top of the support block is rotatably connected to two outer clamping rings.

[0018] This utility model has the following beneficial effects:

[0019] 1. This utility model solves the problem of the single structure of the fixing device in the prior art, which makes it difficult to effectively clamp wires of different thicknesses, by setting a multi-layer sliding sleeve structure composed of a contact ring, a moving ring and a middle clamping ring inside the outer clamping ring. It realizes adaptive clamping of the wiring and improves the fixing reliability.

[0020] 2. This utility model solves the problem in the prior art that the installation position of the fixing device is fixed and cannot flexibly adapt to control modules of different heights in the cabinet by setting a sliding fit structure of sliding rail, sliding block and bearing frame, and setting a mechanical locking structure of buckle, fixing groove and slot. It realizes that the overall position of the fixing mechanism is adjustable and the locking is firm, thus improving the installation flexibility. Attached Figure Description

[0029] To make the objectives, technical solutions, and advantages of this utility model clearer, the technical solutions in the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this utility model, and not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the scope of protection of this utility model.

[0030] Example:

[0031] Please refer to Figures 1 to 6 This utility model provides a modular wiring fixing device for a DCS control system, including an outer casing 1 and a support frame 201. A control module 4 is installed on the inner wall of the outer casing 1. The support frame 201 is used to support the fixing mechanism 2. The modular wiring fixing device for the DCS control system also includes an adjustment mechanism 3 for adjusting the position of the support frame 201.

[0032] The adjusting mechanism 3 includes two sliding rails 301 fixedly connected to the inner wall of the outer casing 1. Two sliding blocks 302 are fixedly connected to the left and right sides of the support frame 201. The two sliding blocks 302 are slidably connected to the inner walls of the two sliding rails 301 respectively. The fixing mechanism 2 includes a support block 202 fixedly connected to the top of the support frame 201. Two outer clamping rings 203 are rotatably connected to the top of the support block 202. A hollow block 207 is fixedly connected to the top of the left outer clamping ring 203. A fixing block 208 is fixedly connected to the top of the right outer clamping ring 203. A locking block 209 is slidably connected to the inner wall of the fixing block 208. The locking block 209 is suitable for sliding and engaging with the inner wall of the hollow block 207. Two middle clamping rings 204 are slidably connected to the inner walls of the two outer clamping rings 203. Two moving rings 205 are slidably connected to the inner walls of the two middle clamping rings 204. Two contact rings 206 are slidably connected to the inner walls of the two moving rings 205.

[0033] The adjustment mechanism 3 also includes two buckles 303 rotatably connected to the front side of the support frame 201. The outer wall of the sliding rail 301 is provided with multiple fixing grooves 304, and the outer wall of the sliding block 302 is provided with a slot 305. The two buckles 303 are adapted to rotatably pass through the fixing grooves 304 and enter the inner wall of the slot 305.

[0034] Please refer to Figure 2 , Figure 3 and Figure 4 The fixing mechanism 2 is located on the top of the support frame 201. The fixing mechanism 2 includes a support block 202 serving as a rotating base. The support block 202 is fixedly connected to the top of the support frame 201 by welding or integral molding. The top of the support block 202 is rotatably connected to two relatively openable outer clamping rings 203 via a rotating shaft. The inner walls of the two outer clamping rings 203 are machined with annular grooves, and two middle clamping rings 204 are slidably connected within these annular grooves. The inner walls of the two middle clamping rings 204 are also slidably connected to two movable rings 205. The moving connection has two contact rings 206 that directly contact the wire harness. When the wire is placed inside the two outer clamping rings 203, the wire first contacts the contact rings 206. When there are many wires, the two contact rings 206 are squeezed and contracted radially, sliding into the inner wall of the two moving rings 205. When there are even more wires, the two moving rings 205 are squeezed and continue to contract into the inner wall of the two middle clamping rings 204. The two middle clamping rings 204 are also squeezed into the inner wall of the outer clamping rings 203. Through this layered nested sliding compression, a continuous pushing force is generated towards the center, thereby adaptively clamping and fixing the wire.

[0035] Please refer to Figure 4To ensure the reliability of clamping, a hollow block 207 is fixedly connected to the top of the left outer clamping ring 203, and a fixing block 208 is fixedly connected to the top of the right outer clamping ring 203. A sliding groove is opened on the inner wall of the fixing block 208, and a locking block 209 is slidably connected in the sliding groove. The locking block 209 is suitable for being manually pushed to slide from the inner wall of the fixing block 208 and engage with the inner wall of the hollow block 207 after the two outer clamping rings 203 are closed. The locking block 209 makes the hollow block 207 and the fixing block 208 engage with each other, thereby fixing the position of the two outer clamping rings 203 and preventing the outer clamping rings 203 from coming off during clamping and causing the wiring to come out. The fixing mechanism 2 is used to clamp and fix the wiring of multiple control modules 4 installed on the inner wall of the outer casing 1.

[0036] As a preferred embodiment, please refer to Figure 1 , Figure 5 and Figure 6 To achieve precise adjustment and reliable locking of the adjustment mechanism 3 in the vertical position, the adjustment mechanism 3 also includes two latches 303. The two latches 303 are symmetrically rotatably connected to the front side wall of the support frame 201. The latches 303 can rotate around the connecting shaft. In order to cooperate with the two latches 303 to achieve the locking function, the outer walls of the two sliding rails 301 fixedly connected to the inner wall of the outer box 1 are provided with multiple fixed grooves 304 arranged at intervals along the vertical length direction. The multiple fixed grooves 304 are through holes, and the diameter of the fixed grooves 304 is adapted to the bolt body of the latches 303, so as to provide multiple selectable fixed height points for the support frame 201.

[0037] The outer walls of the two sliding blocks 302, which are fixedly connected to the left and right sides of the support frame 201, each have a slot 305 at the position corresponding to the two buckles 303. The slot 305 is a groove structure, and the depth of the slot 305 matches the locking end of the buckle 303. The position of the slot 305 corresponds to the position of the fixing groove 304 when the sliding block 302 is at the locking height. When it is necessary to fix the position of the support frame 201, the support frame 201 is first moved up and down within the sliding rail 301 by the sliding block 302 until the buckles 303 on the support frame 201 engage with the locking end of the buckle 303. When a row of fixing slots 304 on the sliding rail 301 are horizontally aligned, the operator can manually rotate the two buckles 303 so that the locking ends of the two buckles 303 pass horizontally through the aligned fixing slots 304 in sequence, and continue to penetrate into the inner wall of the slot 305 on the outer wall of the sliding block 302. The buckles 303 are simultaneously locked between the hole wall of the fixing slot 304 and the slot wall of the slot 305, thus achieving rigid locking between the sliding block 302 and the sliding rail 301, effectively preventing the fixing mechanism 2 and the wire harness carried by the fixing mechanism 2 from falling automatically due to gravity.

[0038] As another preferred embodiment, please refer to Figure 1 and Figure 2The connection relationship of the fixing mechanism 2 is optimized and defined. The support block 202 is fixedly connected to the top of the support frame 201. The lower ends of two outer clamping rings 203 are rotatably connected to the two sides of the top by pins. This rotatable connection structure ensures that the two outer clamping rings 203 can rotate relative to each other around their respective rotation axes on the support block 202 like jaws, thereby realizing the opening or closing action of the clamping space, which facilitates the insertion and removal of the wire harness.

[0039] For a preferred description of the application environment of this utility model, please refer to... Figure 1 Multiple control modules 4 are installed and fixed in an array on the inner wall of the outer casing 1. The control module 4 is the core unit of the DCS system. The fixing mechanism 2 of this utility model is set near or above the multiple control modules 4. It is specifically used to bundle, store and clamp the large number of wires led out from the terminals of the multiple control modules 4 to ensure that the wiring inside the outer casing 1 is neat and the signal is stable.

[0040] Working principle: When the position of the fixing mechanism 2 needs to be adjusted, the operator can push the support frame 201. Since the left and right sides of the support frame 201 are fixedly connected to two sliding blocks 302, and the two sliding blocks 302 are slidably connected to the inner walls of the two sliding rails 301, the support frame 201 can move up and down in the sliding rails 301 through the two sliding blocks 302, and drive the fixing mechanism 2 at the top, thereby realizing the position adjustment of the fixing mechanism 2. After adjusting to the appropriate position, the operator rotates the two buckles 303. Since the outer wall of the sliding rail 301 has multiple fixing grooves 304, and the outer wall of the sliding block 302 has a slot 305, the rotating two buckles 303 will pass through the aligned fixing grooves 304 and enter the inner wall of the slot 305. By simultaneously engaging the fixing grooves 304 and the slots 305 with the buckles 303, the sliding block 302 is fixed, thereby realizing the overall fixation of the fixing mechanism 2, so that the fixing mechanism 2 will not fall automatically due to gravity.

[0041] When it is necessary to fix the wiring of the control module 4, first open the two outer clamping rings 203 connected by rotation, and put the wiring of the control module 4 into the inner wall of the outer clamping rings 203. Since the inner walls of the two outer clamping rings 203 are slidably connected to two middle clamping rings 204, and the inner walls of the two middle clamping rings 204 are slidably connected to two moving rings 205, and the inner walls of the two moving rings 205 are slidably connected to two contact rings 206, when the wiring is put into the inner wall of the two outer clamping rings 203, the wiring will first contact the contact rings 206. When there are many wirings, the two contact rings 206 will be squeezed and retracted into the inner walls of the two moving rings 205. When there are even more wirings, the two moving rings 205 will be squeezed into the inner walls of the two middle clamping rings 204. 204 will also be squeezed into the inner wall of the outer clamping ring 203. Through mutual squeezing, a pushing force will be generated towards the center, thereby adaptively clamping and fixing the wire. After the wire is placed inside the outer clamping ring 203, the two outer clamping rings 203 are closed. Since the top of the left outer clamping ring 203 is fixedly connected to the hollow block 207 and the top of the right outer clamping ring 203 is fixedly connected to the fixing block 208, and the inner wall of the fixing block 208 is slidably connected to the locking block 209, the operator slides the locking block 209 into the inner wall of the left hollow block 207. The locking block 209 makes the hollow block 207 and the fixing block 208 engage with each other, thereby fixing the position of the two outer clamping rings 203 and preventing the wire from coming out during the clamping process.
