Description

Technical Field

[0001] This utility model relates to the field of hardware parts technology, and in particular to an F-type radial locking nut for preventing loosening of prestressed pole tensioning. Background Technology

[0002] A nut, also known as a bolt or screw, is a fastening component used in conjunction with a bolt or screw. Its main function is to securely connect mechanical equipment by engaging with the threads of the bolt or screw through its internal threads, thus achieving a fastening effect.

[0003] While existing nuts and bolts can be fitted together, some problems remain. First, current nuts and bolts require tools for connection, making them inconvenient to operate. Second, current nuts and bolts are prone to loosening after tightening, making them unsuitable for long-term use. Therefore, an F-type radial locking nut for prestressed tensioning of utility poles is needed to solve these problems. Utility Model Content

[0004] The purpose of this utility model embodiment is to provide an F-type radial locking nut for preventing loosening of prestressed pole tensioning, which aims to solve the following problems: existing nuts and bolts require tools to connect and are prone to loosening after tightening.

[0005] This utility model embodiment is implemented as follows: an F-type radial locking nut for prestressed tensioning of utility poles to prevent loosening includes: a handle and a support cover, the support cover and the handle being fixedly connected, and a nut body being fixedly mounted on the support cover; a buffer mechanism, which is fixedly mounted on the nut body, and the buffer mechanism can be placed on the bolt head to facilitate tightening the nut body onto the bolt; and a clamping mechanism, which is installed inside the support cover to press the bolt entering the support cover to prevent the nut body from loosening.

[0006] Preferably, the buffer mechanism includes: a circular groove, which is fixedly mounted on the nut body, a sleeve is slidably mounted in the circular groove, a sleeve rod is slidably mounted in the sleeve, a clamping plate is fixedly mounted on the sleeve rod, the clamping plate can be placed on the bolt head and has an opening for the bolt to pass through; and a buffer spring, whose two ends are fixedly connected to the sleeve and the sleeve rod respectively.

[0007] Preferably, the clamping mechanism includes: a support frame, which is fixedly installed inside the support cover, and a synchronization component is fixedly installed inside the support frame. Two synchronization components are provided and are hinged to clamping plates; a control component, which is installed on the support frame and connected to one clamping plate, for pushing the two clamping plates to approach each other to clamp the bolt; and a slide rod, which is fixedly installed on the inner wall of the support frame, and a slide sleeve fixedly connected to the clamping plate is sleeved on the slide rod.

Detailed Implementation

[0014] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and do not limit the present utility model.

[0015] The specific implementation of this utility model will be described in detail below with reference to specific embodiments.

[0016] Please see Figure 1 This utility model provides an F-type radial locking nut for preventing loosening of prestressed poles, the F-type radial locking nut for preventing loosening of prestressed poles includes:

[0017] The screw handle 1 and the support cover 2 are fixedly connected. The nut body 3 is fixedly installed on the support cover 2. The buffer mechanism 4 is fixedly installed on the nut body 3. The buffer mechanism 4 can be placed on the bolt head to facilitate screwing the nut body 3 onto the bolt. The clamping mechanism 5 is installed inside the support cover 2 to press the bolt that enters the support cover 2 to prevent the nut body 3 from loosening.

[0018] When using the F-type radial locking nut for prestressed tensioning and anti-loosening of the pole, first, press the buffer mechanism 4 against the part to be locked, pass the bolt through the buffer mechanism 4, turn the handle 1, and the handle 1 will drive the nut body 3 to rotate on the buffer mechanism 4, and the nut body 3 can be screwed into the bolt. The buffer mechanism 4 can provide buffering. Turn the clamping mechanism 5, and the clamping mechanism 5 can press the bolt tight, thereby preventing the bolt from loosening.

[0019] like Figure 1 As shown, in a preferred embodiment of the present invention, the buffer mechanism 4 includes: a circular groove 41, which is fixedly mounted on the nut body 3; a sleeve 42 is slidably mounted in the circular groove 41; a sleeve rod 43 is slidably mounted in the sleeve 42; a fastening plate 44 is fixedly mounted on the sleeve rod 43; the fastening plate 44 can be placed on the bolt head and has an opening for the bolt to pass through; and a buffer spring 45, whose two ends are fixedly connected to the sleeve 42 and the sleeve rod 43 respectively.

[0020] After the bolt passes through the fastening plate 44, when the nut body 3 is turned, the nut body 3 will gradually move downwards, thereby compressing the buffer spring 45, which can then play a buffering role.

[0021] like Figure 2 As shown, in a preferred embodiment of the present invention, the clamping mechanism 5 includes: a support frame 51, which is fixedly installed inside the support cover 2, and a synchronization component 52 is fixedly installed inside the support frame 51. Two synchronization components 52 are provided and are hinged to clamping plates 53; a control component 54, which is installed on the support frame 51 and connected to one clamping plate 53, for pushing the two clamping plates 53 to approach each other to clamp the bolt; and a slide rod 55, which is fixedly installed on the inner wall of the support frame 51, and a slide sleeve 56 fixedly connected to the clamping plate 53 is sleeved on the slide rod 55.

[0022] like Figure 2 As shown, in a preferred embodiment of the present invention, the synchronization component 52 includes: a linkage rod 521, which is fixedly installed on the inner wall of the support frame 51 and disposed between two abutment plates 53. A linkage block 522 is sleeved on the linkage rod 521, and a pull rod 523 is hinged on the linkage block 522. The end of the pull rod 523 away from the linkage block 522 is hinged to the abutment plate 53.

[0023] like Figure 2As shown, in a preferred embodiment of the present invention, the control component 54 includes: a threaded cylinder 541, which is rotatably mounted on a support frame 51, and a handle 542 for controlling its rotation is fixedly provided on the threaded cylinder 541; and a threaded rod 543, which is threadedly connected to the threaded cylinder 541 and fixedly connected to a clamping plate 53.

[0024] When tightening the bolt, turn the handle 542. The handle 542 drives the threaded cylinder 541 to rotate. The rotation of the threaded cylinder 541 causes the threaded rod 543 to push a clamping plate 53 to move. The movement of the clamping plate 53 causes a pull rod 523 to push the two linkage blocks 522 away from each other along the linkage rod 521. The two linkage rods 521 moving away from each other causes another pull rod 523 to pull another clamping plate 53 to move. The two clamping plates 53 can then approach each other, thereby tightening the bolt and preventing it from loosening.

[0025] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
