Description

Technical Field

[0001] This utility model relates to the field of turnbuckle technology, specifically a multi-directional stress-dispersing turnbuckle. Background Technology

[0002] Turnbuckles, also known as turnbuckle bolts or rigging screws, are bolts used to tighten steel wires or ropes. A turnbuckle consists of an adjusting rod with left-hand and right-hand threads, a nut, and a pull rod. The adjusting rod is also fitted with an anti-theft and anti-loosening device, which is a combination of a cover plate, a fixing plate, and a guide plate connected by anti-theft and anti-loosening bolts. By rotating the adjusting rod, the nut can be moved on the pull rod, thereby adjusting the tension of the steel wire rope. After disassembly, the anti-theft and anti-loosening device does not need to be removed; it can be adjusted by sliding the guide plate along the pull rod a certain distance.

[0003] Turnbuckles are used for the reinforcement and stabilization of building structures, such as bridges and tower cranes, and are particularly suitable for power lines, such as as positioning devices for high-voltage tower tie rods. Chinese utility model patent CN208919011 U discloses an adjustable turnbuckle, comprising a first adjusting rod for fixed connection to a partition, a second adjusting rod for fixed connection to a base plate, and an adjusting assembly for controlling the distance between the first and second adjusting rods. The end of the second adjusting rod furthest from the base plate is located within the adjusting assembly and moves along the extension direction of the adjusting assembly. Both the first and second adjusting rods are fixedly connected to the adjusting assembly. This utility model controls the distance between the first and second adjusting rods, thereby achieving the effect of adjusting the perpendicularity between the base plate and the partition.

[0004] However, this utility model cannot disperse the stress intensity on the adjusting rod, resulting in excessive stress concentration and an inability to share the load, which easily leads to severe thread wear or damage and a short service life. Therefore, a multi-directional stress-dispersing turnbuckle is proposed to solve the problems mentioned above. Utility Model Content

[0005] To address the shortcomings of existing technologies, this utility model provides a multi-directional stress-dispersing turnbuckle, which has advantages such as reducing stress and improving fatigue resistance. It solves the problem that the stress intensity on the adjusting rod cannot be dispersed, resulting in excessive stress concentration, failure to share the load, and easy occurrence of severe thread wear or damage, leading to a short service life.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] A multi-directional stress-dispersing turnbuckle includes a first bolt rod, a second bolt rod, and an adjusting bracket. Both the first bolt rod and the second bolt rod are provided with stress-dispersing components on their outer sides to reduce stress and improve fatigue resistance.

A hook is fixedly connected to the inside of the adjusting frame. A connecting chain is fixedly connected to the outside of the mounting seat. Fixing frames are fixedly connected to the upper and lower sections of the adjusting frame. Support bolts are threadedly connected to the outside of the fixing frames. A protective structure for enhancing protection is provided on the outside of the adjusting frame.

[0009] Furthermore, the protective structure includes pads fixedly connected to the left and right sides of the adjustment frame, a protective frame is provided on the outer side of the pads, and a buffer plate is bonded between the pads and the protective frame.

[0010] Furthermore, the protective frame is made of aluminum alloy, and the buffer plate is made of foam board.

[0011] Furthermore, an elastic ball head, which is made of rubber, is fixedly connected to the front end of the support bolt.

[0012] Furthermore, the fixing frame is C-shaped, and the inner side of the fixing frame has threaded holes that match the support bolts.

[0013] Furthermore, both the first bolt rod and the second bolt rod are threadedly connected to the auxiliary threaded sleeve, and the top end of the connecting rod is fixedly connected to the inner wall of the adjusting frame.

[0014] Furthermore, the outer surface of the adjustment frame is fitted with four support rods to prevent it from touching the ground.

[0015] Furthermore, the first bolt rod and the second bolt rod have opposite thread directions, and both the first bolt rod and the second bolt rod are threadedly connected to the inner side of the adjusting frame.

[0016] Compared with the prior art, this utility model provides a multi-directional stress-dispersing turnbuckle, which has the following beneficial effects:

[0017] 1. This multi-directional stress-dispersing turnbuckle, by setting a stress-dispersing component, allows two auxiliary threaded sleeves to be threadedly connected to the first bolt rod and the second bolt rod respectively, thereby sharing part of the load.

Detailed Implementation

[0023] 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.

[0024] Please see Figures 1 to 3 The multi-directional stress-dispersing turnbuckle in this embodiment includes a first bolt rod 1, a second bolt rod 2, and an adjustment bracket 3. Both the first bolt rod 1 and the second bolt rod 2 are provided with stress-dispersing components on their outer sides to reduce stress and improve fatigue resistance.

[0025] The stress-dispersing component includes auxiliary threaded sleeves 4 disposed on the outside of the first bolt rod 1 and the second bolt rod 2. A connecting rod 5 is fixedly connected to the outside of the auxiliary threaded sleeves 4. Mounting seats 6 are fixedly connected to the tail ends of the first bolt rod 1 and the second bolt rod 2. A hook 7 is fixedly connected to the inside of the adjusting frame 3. A connecting chain 8 is fixedly connected to the outside of the mounting seat 6. Fixing frames 9 are fixedly connected to the upper and lower sections of the adjusting frame 3. A support bolt 10 is threadedly connected to the outside of the fixing frame 9. A protective structure for enhancing protection is provided on the outside of the adjusting frame 3. The two auxiliary threaded sleeves 4 can be threadedly connected to the first bolt rod 1 and the second bolt rod 2 respectively, thereby sharing part of the load. The mounting seat 6 can be hooked to the hook 7 through the connecting chain 8, thereby pulling the first bolt rod 1 and the second bolt rod 2 up and down, playing an auxiliary pulling role. The support bolt 10 can clamp the first bolt rod 1 and the second bolt rod 2 from the left and right.

[0026] This provides support, reduces cantilever length, lowers bending stress, and thus achieves the function of reducing stress and improving fatigue resistance, effectively extending service life.

[0027] In this embodiment, the protective structure includes pads 12 fixedly connected to the left and right sides of the adjustment frame 3. A protective frame 13 is provided on the outer side of the pads 11. A buffer plate 14 is bonded between the pads 12 and the protective frame 13. The pads 12 and the protective frame 13 achieve the effect of left and right protection. The buffer plate 14 can buffer between the pads 12 and the protective frame 13, thereby reducing the impact force and protecting the outer side of the adjustment frame 3.

[0028] It should be noted that the protective frame 13 is made of aluminum alloy, and the buffer plate 14 is made of foam board.

[0029] Specifically, the front end of the support bolt 10 is fixedly connected to an elastic ball head 11, which is made of rubber. The elastic ball head 11 plays an elastic protective role, thereby preventing the support bolt 10 from damaging the threads of the first bolt rod 1 and the second bolt rod 2.

[0030] It should be noted that the fixing bracket 9 is C-shaped, and the inner side of the fixing bracket 9 is provided with threaded holes that match the support bolts 10. The threaded holes on the inner side of the fixing bracket 9 make it easy for the staff to tighten the support bolts 10 to the outside of the first bolt rod 1 and the second bolt rod 2.

[0031] Specifically, both the first bolt rod 1 and the second bolt rod 2 are threadedly connected to the auxiliary threaded sleeve 4, and the top end of the connecting rod 5 is fixedly connected to the inner wall of the adjusting frame 3. The connecting rod 5 plays the role of installation and connection, thereby ensuring the position of the auxiliary threaded sleeve 4 and preventing displacement.

[0032] It should be noted that the outer surface of the adjustment frame 3 is fitted with four support rods 15 to prevent it from touching the ground. By setting the support rods 15, when the worker lays the adjustment frame 3 flat, the support rods 15 can provide ground support, thereby preventing the adjustment frame 3 from touching the ground.

[0033] Specifically, the threads of the first bolt rod 1 and the second bolt rod 2 are opposite in direction, and both the first bolt rod 1 and the second bolt rod 2 are threadedly connected to the inner side of the adjusting frame 3.

[0034] The working principle of the above embodiments is as follows:

[0035] In use, the operator rotates the first bolt rod 1 and the second bolt rod 2 respectively, connecting them to the tension wire or rope to tighten the wire or rope. During this process, the two auxiliary threaded sleeves 4 can be threadedly connected to the first bolt rod 1 and the second bolt rod 2 respectively, thus sharing part of the load. Then, the connecting chain 8 is picked up and hung on the inside of the hook 7, so that the connecting chain 8 and the hook 7 are engaged. This allows the mounting base 6 to tighten the first bolt rod 1 and the second bolt rod 2 from top to bottom, thereby assisting in pulling and reducing pressure. Finally, the support bolt 10 on the outside of the fixing frame 9 is tightened, so that the front end of the support bolt 10 drives the elastic ball head 11 to approach the threaded part of the first bolt rod 1 and the second bolt rod 2. Finally, the first bolt rod 1 and the second bolt rod 2 are clamped from left and right, thus providing a supporting effect, reducing the cantilever length, reducing bending stress, and improving its service life.

[0036] The installation, connection, or setting methods disclosed in this embodiment are all common mechanical connection methods, and any method that can achieve its beneficial effects can be implemented.

[0037] It should be noted that the orientations or positional relationships indicated herein are based on the orientations or positional relationships shown in the accompanying drawings, and are only for the purpose of facilitating the description of this application and simplifying the description, and are not intended to indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this application.
