Description

Technical Field

[0001] This utility model relates to the field of fixing head technology, specifically to a fixing head that is not easily deformed. Background Technology

[0002] Cable clamps, also known as waterproof cable connectors or cable joints, primarily function to keep the cable outlet sealed and waterproof / dustproof, thereby ensuring the safe and reliable operation of machinery. Currently, cable clamps are widely used in the fixing and protection of wires and cables in mechanical equipment, marine electrical systems, and corrosion-resistant equipment. Most existing cable clamps rely on internal clamping components to hold the cable in place. However, under prolonged use and repeated vibrations, these clamping components are prone to stress concentration, leading to thread stripping or breakage of the clamping claws, resulting in a decrease in cable fixing force. Therefore, a less deformable clamp is proposed. Utility Model Content

[0003] In view of the problems in the prior art, this utility model provides a fixing head that is not easily deformed.

[0004] The technical solution adopted by this utility model to solve its technical problem is a non-deformable fixing head, including a cable and a fixing head body. An anti-detachment sleeve is fixedly sleeved on the outside of the cable. The inside of the fixing head body is used for the installation and insertion of the cable and the anti-detachment sleeve. A sealing ring is embedded in the inner wall of the fixing head body. The sealing ring is sleeved on the outside of the anti-detachment sleeve. An anti-detachment block is movably installed on the outside of the fixing head body. There are multiple anti-detachment blocks. A first limiting plate is fixedly connected to both sides of each anti-detachment block. An installation plate is fixedly sleeved on the outside of the fixing head body. An anti-reverse post is movably connected to the side of the installation plate near the anti-detachment block.

[0005] By adopting the above technical solution, reliable anti-detachment performance is achieved. The anti-detachment sleeve on the outside of the cable cooperates with multiple anti-detachment blocks inside the fixing head body. When the cable is pulled outward, the anti-detachment blocks abut against one side of the anti-detachment sleeve, effectively preventing the cable from being pulled out and ensuring the stability of the internal environment of the equipment. It is suitable for scenarios with high requirements for connection stability.

[0006] Specifically, the first limiting plate is movably installed inside the first sliding groove, which is formed in the inner wall of the fixed head body.

[0007] By adopting the above technical solution, the first limiting plate slides radially along the first sliding groove to prevent the anti-detachment block from detaching from the fixing head body.

[0008] Specifically, the outer side of the fixing head body is provided with a first thread and a second thread, the first thread and the second thread are separated by the mounting plate, and the first thread is adapted to the thread inside the tightening nut.

[0009] By adopting the above technical solution, the first thread is used for the threaded connection of the tightening nut, and the second thread is used for the connection between the fixed head body and the equipment.

[0010] Specifically, the bottom end of the tightening nut has a groove for inserting the anti-reverse post.

[0011] Specifically, the mounting plate has a spring cavity inside, and a spring is installed inside the spring cavity. The top end of the spring is fixedly connected to the bottom end of the second limiting plate, and the top end of the second limiting plate is fixedly connected to the bottom end of the anti-reverse post.

[0012] By adopting the above technical solution, when the tightening nut is tightened to the last few turns, the anti-loosening post will be pressed into the spring cavity and the spring will be compressed until the anti-loosening post is aligned with the groove. The spring will push the anti-loosening post into the groove. In this way, when the tightening nut is tightened, the rotational movement of the tightening nut is restricted because the anti-loosening post is stuck in the groove, thus realizing the anti-loosening function of the tightening nut.

[0013] Specifically, one side of the second limiting plate is fixedly connected to one end of the toggle block, the toggle block is slidably installed inside the second slide groove, the second slide groove is opened on the side of the mounting plate, and the second slide groove communicates with the inside of the spring cavity.

[0014] By adopting the above technical solution, the toggle block slides along the second slide groove, which can realize tool-free manual unlocking. During maintenance, pressing down the toggle block drives the second limit plate to press down, causing the anti-reverse column to retract into the spring cavity. After unlocking, the nut can be rotated in the opposite direction to tighten it.

[0015] The beneficial effects of this utility model are:

[0016] The present invention provides a non-deformable fixing head with reliable anti-detachment performance. The anti-detachment sleeve on the outside of the cable cooperates with multiple anti-detachment blocks inside the fixing head body. When the cable is pulled outward, the anti-detachment blocks abut against one side of the anti-detachment sleeve, effectively preventing the cable from being pulled out and ensuring the stability of the internal environment of the equipment. It is suitable for scenarios with high requirements for connection stability.

[0017] The present invention discloses a non-deformable fixing head with a clever anti-loosening design and convenient maintenance. When the nut is tightened to the last position, the anti-loosening post is engaged in its groove under the action of the spring, restricting the rotation of the nut and realizing the anti-loosening function. The actuating block on the side of the mounting plate is connected to the second limiting plate. During maintenance, pressing down the actuating block can retract the anti-loosening post, which can be manually unlocked without tools, making it convenient to rotate the nut in the opposite direction. This design balances the reliability of the connection with the convenience of later maintenance. Attached Figure Description

Detailed Implementation

[0025] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0026] As one embodiment of this utility model, such as Figures 1-5 As shown, the present invention discloses a non-deformable fixing head, comprising a cable 1 and a fixing head body 4. An anti-detachment sleeve 2 is fixedly sleeved on the outer side of the cable 1. The interior of the fixing head body 4 is used for the installation and insertion of the cable 1 and the anti-detachment sleeve 2. A sealing ring 10 is embedded in the inner wall of the fixing head body 4, and the sealing ring 10 is sleeved on the outer side of the anti-detachment sleeve 2. An anti-detachment block 5 is movably installed on the outer side of the fixing head body 4. There are multiple anti-detachment blocks 5, and a first limiting plate 11 is fixedly connected to both sides of each anti-detachment block 5. An mounting plate 7 is fixedly sleeved on the outer side of the fixing head body 4, and a backstop post 16 is movably connected to the side of the mounting plate 7 near the anti-detachment block 5.

[0027] In use, cable 1 and anti-disengagement sleeve 2 are passed through tightening nut 3 and inserted into the body of fixing head 4, so that anti-disengagement sleeve 2 can pass through the positions of each anti-disengagement block 5 and the sealing ring 10 can be fitted on the outside of anti-disengagement sleeve 2. By installing tightening nut 3, each anti-disengagement block 5 can be pressed into the body of fixing head 4. Since anti-disengagement sleeve 2 is located deeper in the body of fixing head 4, when cable 1 is pulled outward, anti-disengagement sleeve 2 will abut against one end of each anti-disengagement block 5, thus preventing cable 1 from being pulled out.

[0028] The present invention also includes that the first limiting plate 11 is movably installed inside the first slide groove 9, and the first slide groove 9 is formed in the inner wall of the fixed head body 4.

[0029] In use, the first limiting plate 11 slides radially along the first sliding groove 9 to prevent the anti-detachment block 5 from detaching from the fixing head body 4.

[0030] The present invention also includes a first thread 6 and a second thread 8 on the outer side of the fixing head body 4, the first thread 6 and the second thread 8 being separated by the mounting plate 7, and the first thread 6 being adapted to the thread inside the clamping nut 3.

[0031] In use, the first thread 6 is used for the threaded connection of the tightening nut 3, and the second thread 8 is used for the connection of the fixing head body 4 to the equipment.

[0032] The present invention also includes a groove 18 at the bottom end of the tightening nut 3, the groove 18 being used for the insertion of the anti-reverse post 16.

[0033] The present invention also includes a spring cavity 12 inside the mounting plate 7, a spring 17 inside the spring cavity 12, the top end of the spring 17 being fixedly connected to the bottom end face of the second limiting plate 15, and the top end of the second limiting plate 15 being fixedly connected to the bottom end of the anti-reverse post 16.

[0034] When in use, when the tightening nut 3 is tightened to the last few turns, the anti-loosening post 16 will be pressed into the spring cavity 12 and the spring 17 will be compressed until the anti-loosening post 16 is aligned with the groove 18. The spring 17 will push the anti-loosening post 16 into the groove 18. In this way, when the tightening nut 3 is tightened, the rotational movement of the tightening nut 3 is restricted because the anti-loosening post 16 is stuck in the groove 18, thus realizing the anti-loosening function of the tightening nut 3.

[0035] The present invention further includes that one side of the second limiting plate 15 is fixedly connected to one end of the toggle block 14, the toggle block 14 is slidably installed inside the second slide groove 13, the second slide groove 13 is opened on the side of the mounting plate 7, and the second slide groove 13 communicates with the inside of the spring cavity 12.

[0036] When in use, the toggle block 14 slides along the second slide groove 13, which can achieve manual unlocking without tools. During maintenance, pressing down the toggle block 14 will drive the second limit plate 15 to press down, causing the anti-reverse column 16 to retract into the spring cavity 12. After unlocking, the tightening nut 3 can be rotated in the opposite direction.

[0037] In use, the cable 1 and the anti-detachment sleeve 2 are first passed through the tightening nut 3 and inserted into the body 4 of the fixing head. The anti-detachment sleeve 2 passes through the positions of the anti-detachment blocks 5, allowing the sealing ring 10 to be fitted over the outside of the anti-detachment sleeve 2, achieving a sealing effect. Then, the tightening nut 3 is screwed onto the outside of the fixing head body 4 via the first thread 6. As the tightening nut 3 is screwed in, the anti-detachment blocks 5 are pressed into the interior of the fixing head body 4. Because the anti-detachment sleeve 2 is located deeper within the fixing head body 4, this… When the cable 1 is pulled outward, the anti-disengagement sleeve 2 will press against one end of each anti-disengagement block 5 to prevent the cable 1 from being pulled out. Then, when the tightening nut 3 is tightened to the last few turns, the anti-reverse post 16 will be pressed into the spring cavity 12 and the spring 17 will be compressed until the anti-reverse post 16 is aligned with the groove 18. The spring 17 will push the anti-reverse post 16 into the groove 18. In this way, when the tightening nut 3 is tightened, the rotational movement of the tightening nut 3 is restricted because the anti-reverse post 16 is stuck in the groove 18, thus realizing the anti-loosening function of the tightening nut 3.
