Description

Technical Field

[0001] This utility model relates to the field of wiring conduit technology, specifically to a robotic arm for convenient wiring conduit protection. Background Technology

[0002] Cable drag chains, also known as cable protection drag chains, are devices used to secure cables, wires, pneumatic hoses, and hydraulic hoses to facilitate their rotation and movement. They are common wiring conduits for robotic arms. Cable drag chains are divided into steel cable drag chains and plastic cable drag chains. Steel cable drag chains are made of steel and aluminum and can be customized. Plastic cable drag chains are also known as engineering plastic cable drag chains or tank chains. Depending on the usage environment and requirements, cable drag chains are classified into three types: bridge cable drag chains, fully enclosed cable drag chains, and semi-enclosed cable drag chains. Rectangular metal flexible hoses, protective sleeves, corrugated pipes, and metal flexible hoses can also be included in cable drag chain protection and mobile power supply products. Existing cable chains are generally flat and resemble tank tracks. They are composed of numerous unit links that can rotate freely. Each unit link consists of left and right chain plates and upper and lower cover plates. Each link of the cable chain can be opened without threading wires. After opening the cover plate, the wires and cables can be put into the cable chain. It is suitable for use in reciprocating motion applications and can provide traction and protection for the built-in wires and cables. CN220248820U discloses a cable chain for convenient cable routing, consisting of several cable chain knots hinged at both ends. Each cable chain knot includes a main body and a cover plate. The main body includes a left chain plate, a right chain plate, a middle connecting horizontal chain plate, and a main partition plate. The middle connecting horizontal chain plate is located in the middle of the vertical direction between the left and right chain plates, and the main partition plate is located in the middle of the horizontal direction between the left and right chain plates. The middle connecting horizontal chain plate and the main partition plate divide the inner cavity formed by the left and right chain plates into four cable routing cavities. Each cable routing cavity is equipped with a cover plate, one end of which is hinged to the left or right chain plate, and the other end is detachably snapped onto the main partition plate. This cable chain has two independent cable routing cavities on each of its upper and lower surfaces, enabling non-interference operation of different wires and cables during cable routing. Further partition plates within the cable routing cavities allow for orderly routing of multiple wires and cables within a single cavity. Cable routing pads on both sides of the partition plates provide stable clamping and protection for the wires and cables. However, this patent still has the following problems in practical use: The aforementioned device achieves the deformation of the cover plate edge by squeezing and deforming the cover plate edge, using the snap-fit ​​structure to replace the existing spring pin structure. However, both the snap-fit ​​structure and the spring pin insertion positioning require the operator to operate with both hands simultaneously, which is inconvenient. Furthermore, when disassembling, while operating the spring pin laterally, it is also necessary to lift the cover plate. Moreover, due to the low thickness of the cover plate, the actual operating surface of the fingers is also narrow, ultimately resulting in poor operational stability.

[0003] A robotic arm is proposed for convenient wiring and conduit protection to address the problems mentioned above. Utility Model Content

[0004] The purpose of this utility model is to provide a convenient cable management system for robotic arms, which solves the problem of the aforementioned devices in the background art that deform the edge of the cover plate by squeezing it to achieve the buckle structure deformation. The buckle structure replaces the existing spring pin structure. However, both the buckle structure and the spring pin insertion positioning require the operator to operate with both hands simultaneously, which is inconvenient. Furthermore, when disassembling, the operator needs to lift the cover plate while operating the spring pin laterally. Moreover, due to the low thickness of the cover plate, the actual operating surface of the fingers is also narrow, resulting in poor operational stability.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a convenient cable tray for robotic arms, comprising a drag chain body, wherein the drag chain body comprises chain links, each chain link comprises a pair of chain plates, and a support plate is fixedly connected to the bottom of each chain plate; The top of the chain plate is provided with a shielding component, the shielding component includes a top cover, a guide frame is fixedly connected to one side of the top cover, a docking frame is fixedly connected to the top of one of the chain plates, and a hollow block is slidably connected inside the guide frame; The hollow block is fixedly connected to one side with a pin, and a pressing toothed column is vertically slidably connected to the middle of the hollow block. The hollow block is symmetrically provided with a support shaft and a lifting rack inside, and an intermediate toothed cylinder is fixedly sleeved on the outside of the support shaft. The pressing tooth column is fixedly connected to a pressing plate at its top end, a sponge pad is fixedly connected to its bottom end, a spring is fixedly connected to its top end, and a locking pin is fixedly connected to its bottom end.

[0006] Preferably, the other side of the top cover is hinged to the top of another chain plate, the pin is connected through one side of the guide frame, and the end of the pin is inserted into one side of the docking frame. The guide frame overlaps with the top surface of one of the chain plates, and the bottom surface of the sponge pad is fixedly connected to the inner bottom surface of the hollow block.

[0007] Preferably, the pressing tooth column has symmetrical teeth on both sides, the two ends of the support shaft are rotatably connected to the inner wall of the hollow block, and the support shaft is fixedly connected to the intermediate tooth cylinder.

[0008] Preferably, one side of the intermediate toothed cylinder is engaged with one side of the pressing toothed column, and the other side of the intermediate toothed cylinder is engaged with the lifting rack.

[0009] Preferably, the top end of the spring is fixedly connected to the inner top surface of the hollow block, the locking pin slides through the bottom of the hollow block, and the bottom of the locking pin is inserted into the inner bottom surface of the guide frame.

[0010] Preferably, the top surface of the support plate is provided with a partition component, the partition component includes a pair of partition plates, the top end of the partition plates is fixedly connected to a pair of arc-shaped baffles, the bottom center of the partition plates is fixedly connected to a threaded post, and the top surface of the support plate is symmetrically provided with a positioning groove and a through hole, the through hole being located in the center of the positioning groove.

[0011] Preferably, the bottom of the partition plate is inserted into the positioning groove, the threaded post is connected through the through hole, and a nut is threadedly connected to the bottom of the threaded post.

[0012] Compared with the prior art, the beneficial effects of this utility model are: This robotic arm provides convenient wiring protection, and the shielding component uses a vertical pressing drive gear rack transmission to integrate the vertical withdrawal of the locking pin and the horizontal disengagement of the pin into a single continuous action, realizing one-handed, fast, and accident-proof opening and closing of the top cover. Its internal buffer and damping structure further improves the operating feel and locking stability. The specific details are as follows: 1. Through a sophisticated gear and rack transmission mechanism, the single vertical pressing action is broken down into two consecutive steps: the vertical withdrawal of the locking pin and the horizontal disengagement of the pin column, enabling rapid one-handed opening and closing of the top cover. This design eliminates the need for simultaneous, laborious lateral operation or lifting of the spring pins at both ends, as required in traditional cable chains. It effectively avoids slippage caused by small contact surfaces, making the operation intuitive, effortless, and efficient. Moreover, the simultaneous locking of one side by both pins greatly increases installation stability. The internal sponge pad not only provides cushioning support for the pressing pin column but also reduces the potential wobbling of the locking pin caused by the spring by increasing the damping effect, improving transmission stability and operating feel, making wiring and maintenance work simpler and more convenient.

[0013] 2. The arc-shaped baffle at the top of the partition plate effectively prevents cables from accidentally crossing the partition during cable chain operation, improving the orderliness and safety of cable management. The threaded post at the bottom cooperates with the nut to provide a firm lock, while the clearance cavity designed at the bottom of the support plate ensures that the nut is fully embedded and does not protrude after locking, completely eliminating the risk of the cable chain being obstructed or damaged by bottom obstacles during movement, ensuring the stability and reliability of the cable chain operation, while making the cable layout clear and easy to classify, lay out and manage.

[0016] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0017] Please see Figures 1-5 The present invention provides a technical solution: a convenient cable protection tube for robotic arms, including a cable chain body, the cable chain body including a chain link 1, the chain link 1 including a pair of chain plates 101, and a support plate 102 fixedly connected to the bottom of the chain plate 101; the chain link 1 is an independent unit of the cable chain body, and different units are hinged together.

[0018] A shielding assembly 2 is provided on the top of the chain plate 101. The shielding assembly 2 includes a top cover 201. A guide frame 202 is fixedly connected to one side of the top cover 201. A docking frame 203 is fixedly connected to the top of one chain plate 101. A hollow block 204 is slidably connected inside the guide frame 202. A pin 205 is fixedly connected to one side of the hollow block 204. A pressing tooth 206 is vertically slidably connected to the middle of the hollow block 204. A support shaft 207 and a lifting rack 209 are symmetrically arranged inside the hollow block 204. A middle toothed cylinder 208 is fixedly sleeved on the outside of the support shaft 207. A pressing plate 210 is fixedly connected to the top of the pressing tooth 206. A sponge pad 211 is fixedly connected to the bottom of the pressing tooth 206. A spring 212 is fixedly connected to the top of the lifting rack 209. A locking pin 213 is fixedly connected to the bottom of the lifting rack 209. When wiring is required, first press... Pressing the pressing plate 210 causes the pressing pin 206 to slide vertically downwards. Through the transmission of the intermediate gear cylinder 208 and the support shaft 207, the lifting rack 209 moves upwards. As the spring 212 contracts, the locking pin 213 is pulled out from the inner bottom surface of the guide frame 202, canceling the plug-in locking state. Then, the direction of force applied by pressing the pressing plate 210 is changed, generating an oblique pushing force. The pressing plate 210 will drive the hollow block 204 and the pin 205 to move horizontally together under the action of the oblique component force. The horizontal movement causes the pin 205 to be pulled out from the docking frame 203. At this time, the top cover 201 can be directly flipped open for easy wiring. The vertical locking can be released first by a single vertical pressing operation, followed by horizontal separation, which simplifies the operation steps and avoids the inconvenience of multi-step simultaneous operation that may exist in traditional structures. The whole process is simple and convenient to operate with one hand.

[0019] The other side of the top cover 201 is hinged to the top of another chain plate 101. The pin 205 is connected through to one side of the guide frame 202, and the end of the pin 205 is inserted into one side of the docking frame 203. The guide frame 202 overlaps with the top surface of one chain plate 101. The bottom surface of the sponge pad 211 is fixedly connected to the inner bottom surface of the hollow block 204. When the pressing tooth 206 moves down, the sponge pad 211 is compressed, which can play a buffering and damping role. When the pressing plate 210 is released, the elastic restoring force of the sponge pad 211 helps the pressing tooth 206 to return to its original position, and cooperates with the spring 212 to maintain the stability of the lifting rack 209 and the locking pin 213 in the locked position.

[0020] The pressing tooth column 206 has symmetrical teeth on both sides. The two ends of the support shaft 207 are rotatably connected to the inner wall of the hollow block 204. The support shaft 207 is fixedly connected to the middle tooth cylinder 208. The pressing tooth column 206 cooperates with the protrusion in the hollow block 204 through the guide groove of the side wall to achieve stable vertical lifting. One side of the middle tooth cylinder 208 is meshed with one side of the pressing tooth column 206, and the other side of the middle tooth cylinder 208 is meshed with the lifting rack 209.

[0021] The top of the spring 212 is fixedly connected to the inner top surface of the hollow block 204, and the locking pin 213 slides through the bottom of the hollow block 204. The bottom of the locking pin 213 is inserted into the inner bottom surface of the guide frame 202. The locking pin 213 is inserted into the inner bottom surface of the guide frame 202 to lock the horizontal position of the hollow block 204 in the non-operating state.

[0022] The top surface of the support plate 102 is provided with a partition component 3, which includes a pair of partition plates 301. A pair of arc-shaped baffles 302 are fixedly connected to the top of the partition plates 301, and a threaded post 303 is fixedly connected to the middle of the bottom end of the partition plates 301. The top surface of the support plate 102 is symmetrically provided with a positioning groove 304 and a through hole 305, and the through hole 305 is located in the middle of the positioning groove 304. The partition plates 301 can divide the support plate 102 into several cavities, which facilitates the separate arrangement of different types of gas pipes or liquid pipes. The arc-shaped structure of the arc-shaped baffles 302 increases the difficulty for cables to cross the partition plates 301. The bottom of the partition plate 301 is inserted into the positioning groove 304, and the threaded post 303 is connected through the through hole 305. The bottom of the threaded post 303 is threaded with a nut 306. The bottom surface of the support plate 102 has a clearance cavity. The depth of the clearance cavity is greater than the height of the nut 306 and is located below the position of the through hole 305. After the partition plate 301 is inserted into the positioning groove 304 on the support plate 102, the threaded post 303 and the nut 306 are connected to achieve quick locking. Moreover, after installation, the nut 306 will be embedded in the clearance cavity on the bottom surface of the support plate 102 to prevent the protrusion of the nut 306 from affecting the movement of the cable chain.

[0023] Working principle: Before using this robotic arm for convenient cable management and conduit protection, it is necessary to check the overall condition of the device to ensure it can function properly. Figure 1 - Figure 5 As shown, firstly, the pressing plate 210 on one side of the top cover 201 is pressed vertically downward, driving the pressing tooth column 206 to slide vertically down inside the hollow block 204. Pressing the toothed column 206 drives the intermediate toothed cylinder 208 to rotate through the teeth on its side. The intermediate toothed cylinder 208 then drives the lifting rack 209, which meshes with it, to move upward, compressing the spring 212 and causing the locking pin 213 to be completely pulled out from the inner bottom surface of the guide frame 202, thus releasing the vertical lock on the hollow block 204. Subsequently, while maintaining the downward pressure, a force is applied laterally, that is, away from the docking frame 203. This oblique force causes the entire hollow block 204, together with the pin 205 on it, to slide horizontally within the guide frame 202 until the pin 205 is completely dislodged from the docking frame 203. At this point, the top cover 201 is connected by a hinge on only one side and can be easily flipped open for wiring operations. Closing is achieved by reversing the operation, and the locking process is smooth. For the separator assembly 3, during installation, the threaded post 303 at the bottom of the separator plate 301 is aligned with the through hole 305 on the support plate 102 and inserted. Simultaneously, the bottom of the separator plate 301 is embedded in the positioning groove 304 for initial positioning. Finally, the nut 306 is tightened from the bottom of the support plate 102 to complete the fixation. The nut 306 is housed in the clearance cavity at the bottom of the support plate 102, ensuring no interference during cable chain movement.

[0024] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
