Description

Technical Field

[0001] This utility model relates to the field of iron tower reinforcement technology, specifically to an anti-loosening fastener for iron tower bolts. Background Technology

[0002] In the field of tower reinforcement technology, as an important infrastructure for industries such as power and communications, towers are subjected to harsh natural conditions such as wind, sun, rain, strong winds, and earthquakes for a long time. Under continuous vibration and alternating loads, the connecting bolts are prone to loosening. Once the bolts loosen, the stability of the tower structure will be seriously threatened, which may lead to safety accidents such as tower tilting and collapse. Therefore, it is necessary to use fasteners to reinforce the bolts at key connection points of the tower.

[0003] When using existing fasteners to reinforce tower bolts in mountainous areas, the complex terrain and turbulent airflow make the towers more susceptible to the effects of high-altitude airflow, which can easily cause violent shaking at the bolt connections. These environmental factors make the fasteners more prone to damage and aging, reducing their fastening performance and affecting the stability of the tower structure. Therefore, it is urgent to develop a tower bolt anti-loosening fastener to solve these practical problems. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model provides a tower bolt anti-loosening fastener, which solves the problem that when reinforcing tower bolts in mountainous areas, the complex terrain causes airflow turbulence, and the tower bolts sway violently due to the high-altitude airflow. Existing fasteners are easily damaged and aged due to this, resulting in reduced fastening performance and endangering the stability of the tower structure.

[0005] To achieve the above objectives, this utility model provides a tower bolt anti-loosening fastener through the following technical solution: a fastener body, wherein a through hexagonal bolt is installed inside the fastener body.

[0006] It also includes a pressing fastening mechanism, which includes a fixing sleeve fitted onto the top of the hexagonal bolt. Multiple sets of baffles are installed at equal intervals on the outside of the fixing sleeve, and the baffles are arranged radially with respect to the axis of the fixing sleeve. A pressing seat is also inserted inside the fastener body. The pressing seat has pressing grooves at equal intervals corresponding to the baffles. A limiting component is provided at the bottom of the pressing seat to cooperate with the fastener body and to limit the position of the pressing seat within the fastener body. A pressing component is provided at the top of the fastener body to resist the movement of the pressing seat.

[0007] Preferably, the limiting component includes multiple sets of limiting blocks disposed at the bottom of the lower pressure seat, and the bottom of the fastener body is provided with limiting grooves corresponding to the limiting blocks at equal intervals, and the inner wall specifications of the limiting grooves are adapted to the limiting blocks.

[0008] Preferably, the pressing component includes a fixed plate disposed on the top of the fastener body, and a threaded seat extending into the interior of the fastener body is fixedly connected to the bottom of the fixed plate. The threaded seat is threadedly connected to the inner wall of the fastener body, and the bottom of the threaded seat is in contact with the top of the pressing seat. A rubber sleeve is also sleeved on the outside of the fixed plate, and the rubber sleeve is made of silicone material to increase the friction when operating the fixed plate.

[0009] Preferably, the axes of the fixed disc, threaded seat, and lower pressure seat are collinear with the center line of the fastener body.

[0010] Preferably, the top of the fixing plate is also coated with an epoxy resin coating to isolate external rainwater from contact with the fixing plate.

[0011] Preferably, a washer is provided at the bottom of the fastener body to increase the contact area between the fastener body and the object being fixed, and the bottom end of the hexagonal bolt passes through the washer.

[0012] This utility model provides a bolt anti-loosening fastener for iron towers. Compared with the prior art, it has the following advantages.

[0021] 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.

[0022] First implementation method:

[0023] refer to Figure 1-5 A tower bolt anti-loosening fastener includes a fastener body 1, and a through hexagonal bolt 101 is installed inside the fastener body 1.

[0024] It also includes a pressing fastening mechanism 2, which includes a fixing sleeve 201 sleeved on the top of the hexagonal bolt 101. Multiple sets of baffles 202 are installed at equal intervals on the outside of the fixing sleeve 201, and the baffles 202 are arranged radially with respect to the axis of the fixing sleeve 201. A pressing seat 203 is also inserted inside the fastener body 1. The pressing seat 203 has pressing grooves 204 corresponding to the baffles 202 at equal intervals inside. A limiting component that works with the fastener body 1 is provided at the bottom of the pressing seat 203 to limit the position of the pressing seat 203 inside the fastener body 1. A pressing component 3 for resisting the movement of the pressing seat 203 is provided at the top of the fastener body 1.

[0025] The limiting component includes multiple sets of limiting blocks 205 disposed at the bottom of the lower pressure seat 203. The bottom of the fastener body 1 is provided with limiting grooves 206 corresponding to the limiting blocks 205 at equal intervals, and the inner wall specifications of the limiting grooves 206 are adapted to the limiting blocks 205.

[0026] The bottom of the fastener body 1 is also provided with a washer 4 to increase the contact area between the fastener body 1 and the object being fixed, and the bottom end of the hexagonal bolt 101 passes through the washer 4.

[0027] After placing the shim 4 at the bottom of the fastener body 1, align the shim 4 with the center of the fastener body 1, and insert the hex bolt 101 into the fastener body 1 and the shim 4 until it is connected to the external tower equipment.

[0028] The gasket 4 mainly increases the contact area with the tower mounting surface, disperses the pressure generated when the hexagonal bolt 101 is tightened, improves the overall stability of the tightening, and reduces the damage to the tower mounting parts caused by excessive local pressure.

[0029] By rotating the hex bolt 101, the relative position of the washer 4 and the fastener body 1 is fixed, and the hex bolt 101 is screwed into the tower installation position to complete the initial installation.

[0030] The operator inserts the lower pressure seat 203 into the fastener body 1, so that the cross baffle 202 on the outside of the fixing sleeve 201 enters the corresponding pressure groove 204 inside the lower pressure seat 203 and abuts against each other.

[0031] During the movement of the lower pressure seat 203, it drives the limiting block 205 at its bottom to move into the corresponding limiting groove 206 at the bottom of the fastener body 1, thereby limiting the rotation position of the lower pressure seat 203. The fixed lower pressure seat 203 can limit the rotation position of the fixing sleeve 201 sleeved on the top of the hexagonal bolt 101 through the cooperation of the pressing groove 204 and the cross baffle 202, thereby restricting the rotation of the hexagonal bolt 101 and preventing the hexagonal bolt 101 from rotating loose due to vibration or other external forces. This achieves the function of preventing the tower bolts from loosening and solves the problem that the tower bolts are easy to loosen during use, affecting the stability of the tower structure.

[0032] Second implementation method:

[0033] When using existing fasteners to reinforce tower bolts in coastal areas, the high humidity and salinity of the air, coupled with the strong long-term erosion effect of rainwater, make the fasteners more susceptible to damage and aging, reducing their fastening performance and affecting the stability of the tower structure.

[0034] refer to Figure 4 In the second embodiment of this utility model, the pressing component 3 includes a fixed plate 301 disposed on the top of the fastener body 1. A threaded seat 302 extending into the interior of the fastener body 1 is fixedly connected to the bottom of the fixed plate 301. The threaded seat 302 is threadedly connected to the inner wall of the fastener body 1, and the bottom of the threaded seat 302 abuts against the top of the pressing seat 203. A rubber sleeve 303 is also sleeved on the outside of the fixed plate 301. The rubber sleeve 303 is made of silicone material to increase the friction when operating the fixed plate 301.

[0035] The axes of the fixed plate 301, threaded seat 302, and pressure seat 203 are collinear with the center line of the fastener body 1. The top of the fixed plate 301 is also coated with an epoxy resin coating 304 to isolate external rainwater from contact with the fixed plate 301.

[0036] By rotating the fixed plate 301, the operator can drive the threaded seat 302, which is fixed to its bottom, to be screwed into the fastener body 1, so that the bottom of the threaded seat 302 abuts against the top of the pressure seat 203, further limiting the movement of the pressure seat 203.

[0037] Meanwhile, the fixing plate 301 can seal the top of the fastener body 1, realizing the protection function and avoiding the problem of rust and corrosion caused by external rainwater directly contacting the hexagonal bolt 101. This solves the problem of bolt rust affecting the fastening effect and shortening the bolt's service life.

[0038] The epoxy resin coating 304 utilizes its excellent waterproof and corrosion-resistant properties to further enhance the protection of the top of the fixed plate 301 against rainwater, preventing rainwater from penetrating into the interior and affecting the performance of the components.

[0039] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
