Description

Technical Field

[0001] This utility model relates to the field of servo connection cable technology, and in particular to an oil-resistant power servo connection cable. Background Technology

[0002] Oil-resistant power servo cables typically refer to cables or connectors used in power servo systems. They are specifically designed to resist oil, chemicals, and potential mechanical wear. These cables are widely used in industrial fields requiring high reliability and long-term durability, such as mechanical automation, robotics, and hydraulic systems.

[0003] Existing technologies, such as the utility model patent with publication number CN223321039U, disclose a wear-resistant connecting cable for a servo motor. This patent employs a connecting cable body and anti-friction components. Multiple anti-friction components are evenly installed on the outer surface of the connecting cable body. The anti-friction components include a grounding ring, a spherical groove, and a rolling ball. The grounding ring is fixedly disposed on the outer surface of the connecting cable body. By providing multiple anti-friction components evenly spaced on the outside of the cable, when the connecting cable body of the servo motor comes into contact with the equipment during bending and stretching, the anti-friction components first contact the equipment, preventing the connecting cable body from contacting the equipment and preventing damage to the connecting cable body. Furthermore, the rolling ball on the anti-friction component extends out of the opening of the spherical groove. When the anti-friction component contacts the equipment, the rolling ball will first contact the surface of the equipment and roll on the equipment, changing sliding friction into rolling friction, reducing the wear of the anti-friction components, and increasing the service life of the anti-friction components and the connecting cable body.

[0004] In the existing technology, when using servo connection cables, there will be situations where the connection cable needs to be forcibly bent to a specific angle to connect due to the fixed position of the device interface. This will lead to continuous stress on the connection cable at the bend, resulting in accelerated wear of the surface protective layer, fatigue damage to the internal wire core, or even breakage. Utility Model Content

[0005] The purpose of this invention is to solve the problem that in the use of servo connection cables, when the device interface position is fixed, the connection cable needs to be forcibly bent to a specific angle to connect, which leads to continuous stress at the bending point, accelerated wear of the surface protective layer, fatigue damage or even breakage of the internal wire core. The proposed invention is an oil-resistant power servo connection cable.

[0006] To achieve the above objectives, this utility model adopts the following technical solution: a servo connection cable body, wherein a connector and a locking ring are mounted on the arc surface of the servo connection cable body, the locking ring is threadedly connected to the connector, and the arc surface of the locking ring is provided with a limiting structure, the limiting structure including a connecting cover, the connecting cover being rotatably connected to the locking ring, the connecting cover being movably connected to the servo connection cable body, two connecting blocks being fixedly connected to the side of the connecting cover away from the locking ring, and a rotating tube being rotatably connected to the side of the two connecting blocks close to each other, the rotating tube being movably connected to the servo connection cable body, and two limiting grooves and several positioning holes being formed on the inner wall of the rotating tube, the several positioning holes being connected to the limiting grooves and the locking ring being rotatably connected to the locking ring. The grooves are interconnected. Protective pads are fixedly connected to the inner walls of the rotating tube and the connecting cover. A fixing frame is fixedly connected to the upper surface of the connecting cover. A fixing rod is fixedly connected to the inner wall of the fixing frame. Two moving blocks are slidably connected to the arc surface of the fixing rod. Two springs are sleeved on the arc surface of the fixing rod. The two ends of the springs are fixedly connected to the moving blocks and the fixing frame, respectively. A fixing column is fixedly connected to the side of the moving block near the rotating tube. A limit rod is rotatably connected to the ends of the two fixing columns that are far apart from each other. A positioning rod is fixedly connected to the arc surface of the limit rod. A connecting rod is slidably connected to the arc surface of the positioning rod. The limit rod is slidably connected to the positioning hole and the limit groove.

[0007] The effect achieved by the above components is as follows: After the operator inserts the connector into the device, the operator can move the two moving blocks according to the position of the next interface, so that the limit rod slides out of the inner wall of the positioning hole. Then the operator rotates the rotating tube, which drives the servo cable body to rotate until the rotating tube rotates to the appropriate angle. Then the operator releases the moving blocks, and the spring rebounds, causing the limit rod to slide into the inner wall of the positioning hole. This can prevent wear and damage to the surface of the servo cable body caused by improper bending angle, and improve the service life of the servo cable body.

[0008] Preferably, the arc surface of the spring is fitted with a bellows, and the two ends of the bellows are fixedly connected to the moving block and the fixed frame, respectively.

[0009] The effect achieved by the above components is that the bellows can protect the spring, prevent other substances from coming into direct contact with the spring, and thus improve the service life of the spring.

[0010] Preferably, the inner wall of the fixing frame is fixedly connected to two limiting blocks.

[0011] The effect achieved by the above components is that the limiting block can limit the movement of the moving block, preventing the limiting rod from completely sliding out of the inner wall of the limiting groove during the movement of the moving block.

[0012] Preferably, an auxiliary block is fixedly connected to the upper surface of the movable block.

[0013] The effect achieved by the above components is that the auxiliary block makes it easier for personnel to move the movable block, thereby improving the ease of operation for personnel.

[0014] Preferably, anti-slip pads are fixedly connected to the sides of the two auxiliary blocks that are close to each other, and the anti-slip pads have a rectangular cross-section.

[0015] The effect achieved by the above components is that the anti-slip mat can increase the friction between the person's hand and the moving block, and can prevent the person from slipping when moving the moving block.

[0016] Preferably, each of the two limiting rods has a guide block fixedly connected to one end of each other, and the guide block is slidably connected to the positioning hole.

[0017] The effect achieved by the above components is that the guide block can guide the limiting rod, making it convenient for personnel to slide the limiting rod into the inner wall of the positioning hole.

[0018] In summary, the beneficial effects of this utility model are as follows:

[0019] In this invention, by operating the limiting structure, the bending angle of the servo cable body can be limited when the connector is inserted into the device for use. This prevents wear and damage to the surface of the servo cable body caused by improper bending angle, thereby extending the service life of the servo cable body. Attached Figure Description

[0025] The present invention will be further illustrated below with reference to specific embodiments. It should be understood that these embodiments are for illustrative purposes only and are not intended to limit the scope of the present invention. Furthermore, it should be understood that after reading the teachings of this invention, those skilled in the art can make various alterations or modifications to the present invention, and these equivalent forms also fall within the scope defined by the appended claims.

[0026] Reference Figure 1 As shown, this utility model provides a technical solution: an oil-resistant power servo connection cable, including a servo connection cable body 1, a connector 4 and a locking ring 2 installed on the arc surface of the servo connection cable body 1, the locking ring 2 being threadedly connected to the connector 4, and the arc surface of the locking ring 2 being provided with a limiting structure 3.

[0027] The specific settings and functions of its limiting structure 3 will be discussed below.

[0028] Reference Figures 2 to 4As shown in this embodiment: the limiting structure 3 includes a connecting cover 301, which is rotatably connected to the locking ring 2 and movably connected to the servo connection cable body 1. Two connecting blocks 303 are fixedly connected to the side of the connecting cover 301 away from the locking ring 2. A rotating tube 304 is rotatably connected to the side of the two connecting blocks 303 that are close to each other. The rotating tube 304 is movably connected to the servo connection cable body 1. Two limiting grooves 305 and several positioning holes 306 are opened on the inner wall of the rotating tube 304. The several positioning holes 306 communicate with the limiting grooves 305. Protective pads 302 are fixedly connected to the inner walls of both the rotating tube 304 and the connecting cover 301. A fixing bracket 3 is fixedly connected to the upper surface of the connecting cover 301. 08. A fixing rod 318 is fixedly connected to the inner wall of the fixing frame 308. Two moving blocks 310 are slidably connected to the arc surface of the fixing rod 318. Two springs 314 are sleeved on the arc surface of the fixing rod 318. The two ends of the springs 314 are fixedly connected to the moving blocks 310 and the fixing frame 308 respectively. A fixing column 315 is fixedly connected to the side of the moving block 310 near the rotating tube 304. A limit rod 307 is rotatably connected to the ends of the two fixing columns 315 that are far apart from each other. A positioning rod 316 is fixedly connected to the arc surface of the limit rod 307. A connecting rod 317 is slidably connected to the arc surface of the positioning rod 316. The limit rod 307 is slidably connected to the positioning hole 306 and the limit groove 305. After the operator inserts the connector 4 into the device, the operator can move the two moving blocks 310 according to the position of the next interface, so that the limit rod 307 slides out of the inner wall of the positioning hole 306. Then the operator rotates the rotating tube 304, which drives the servo connection cable body 1 to rotate until the rotating tube 304 rotates to a suitable angle. Then the operator releases the moving block 310, at which point the spring 314 rebounds, so that the limit rod 307 slides into the inner wall of the positioning hole 306. This can prevent wear and damage to the surface of the servo connection cable body 1 caused by improper bending angle, thereby improving the service life of the servo connection cable body 1. The arc surface of the spring 314 is fitted with a corrugated tube 311, and the two ends of the corrugated tube 311 are fixedly connected to the moving block 310 and the fixed frame 308, respectively. The bellows 311 protects the spring 314, preventing direct contact between it and other substances, thus extending its service life. Two limiting blocks 309 are fixedly connected to the inner wall of the fixing frame 308. These limiting blocks 309 limit the movement of the moving block 310, preventing the limiting rod 307 from completely sliding out of the inner wall of the limiting groove 305 during movement. An auxiliary block 312 is fixedly connected to the upper surface of the moving block 310. The auxiliary block 312 facilitates movement of the moving block 310, improving ease of operation. Anti-slip pads 313, with rectangular cross-sections, are fixedly connected to the sides of the two auxiliary blocks 312 that are close to each other.The anti-slip pad 313 increases the friction between the operator's hand and the movable block 310, preventing slippage during movement. Guide blocks 319 are fixedly connected to the ends of the two limiting rods 307 that are close to each other, and these guide blocks 319 are slidably connected to the positioning holes 306. The guide blocks 319 guide the limiting rods 307, facilitating the sliding of the limiting rods 307 into the inner wall of the positioning holes 306.

[0029] Detailed Instructions for Use: When inserting connector 4 into the device, the operator first installs connector 4 onto the servo cable body 1, then secures and stabilizes connector 4 using locking ring 2. Next, the operator inserts connector 4 into the device for connection. Then, using the two anti-slip pads 313, the operator moves auxiliary block 312 away from each other. The anti-slip pads 313 increase the friction between the operator's hand and the moving block 310, preventing slippage during movement. The auxiliary block 312 then moves the moving block 310 towards the two moving blocks 310. The moving block 310 moves in a direction away from each other. The auxiliary block 312 facilitates movement of the moving block 310, improving operational convenience. The moving block 310 then stretches the bellows 311 and spring 314. The bellows 311 protects the spring 314, preventing direct contact with other substances and extending its lifespan. The moving block 310 also moves the fixed column 315 in a direction away from each other. The fixed column 315 then moves the limiting rod 307 away from the connecting rod 317. 307 drives the positioning rod 316 and guide block 319 to move away from the positioning hole 306. The two positioning rods 316 slide on the inner wall of the connecting rod 317. The guide block 319 guides the limiting rod 307, making it easy for personnel to slide the limiting rod 307 into the inner wall of the positioning hole 306 until the moving block 310 abuts against the limiting block 309. The limiting block 309 limits the moving block 310, preventing the limiting rod 307 from completely sliding out of the inner wall of the limiting groove 305 during the movement of the moving block 310. At this point, the limiting rod 307 and guide block 319 will slide out of the positioning hole. The inner wall of 306 allows the guide block 319 and part of the limiting rod 307 to be located on the inner wall of the limiting groove 305. Then, the operator rotates the rotating tube 304 according to the position of the next interface, causing the rotating tube 304 to drive one of the protective pads 302 to rotate. At this time, the guide block 319 and the limiting rod 307 slide on the inner wall of the limiting groove 305 until the rotating tube 304 rotates to a suitable angle. Then, the operator releases the anti-slip pad 313, at which point the spring 314 rebounds, causing the two limiting rods 307 to move towards the positioning hole 306 until the guide block 319 and the limiting rod 307 slide into the inner wall of the positioning hole 306.
