[0002] Cables are cables made of ropes, steel cables or other similar materials used to provide support and tension. When setting up a mesh tent, cable fastening structures are used to tighten and secure the cables, which typically rely on standard bolts and turnbuckles for tightening and fixing.

[0003] Existing turnbuckles may cause the lead screw to strip when the steel cable is tightened for a long time, causing the lead screw to come out of the turnbuckle body and causing unnecessary trouble.

[0004] The existing patent (publication number: CN217422034U) describes a turnbuckle with a washer eye. In this utility model, two anti-reverse washers are threadedly connected to one end of the two screw rods inside the turnbuckle. In this way, if the screw rods slip when tightening steel cables for a long time, the two screw rods can be prevented from completely coming out of the turnbuckle under the action of the anti-reverse washers, thereby avoiding unnecessary trouble.

[0005] To address the aforementioned issues, existing patents have provided solutions. However, most existing turnbuckles lack a self-locking structure, which means that under repeated wind and vibration, the turnbuckles are prone to loosening during long-term use. This leads to a decrease in cable tension, making it difficult to provide sufficient support and affecting the overall stability of the tent.

[0006] To address this, a high-strength wind-resistant cable fastening structure for mesh tents is proposed. Utility Model Content

[0027] 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.

[0028] Please see Figures 1-6 The present invention provides the following technical solution:

[0029] A high-strength wind-resistant cable fastening structure for a mesh tent includes two fastening bolts 1. Each of the two fastening bolts 1 has a cross-shaped groove 2 at one end opposite to the other. A locking component 3 is engaged with the inner wall of the cross-shaped groove 2. Matching components 4 are fixedly connected to both sides of the locking component 3.

[0030] The locking assembly 3 includes a cross block 301, the surface of which engages with the inner wall of the cross slot 2. A ratchet 302 is fixedly connected to the rear side of the cross block 301, and a fixing plate 303 is rotatably connected to the rear side of the ratchet 302. Fixing blocks 304 are fixedly connected to both sides of the front side of the fixing plate 303, and a first spring 305 is fixedly connected to the opposite side of the fixing block 304. A pawl 306 is fixedly connected to the end of the first spring 305 away from the fixing block 304. The side of the pawl 306 near the fixing plate 303 is rotatably connected to the fixing plate 303, and the pawl 306 engages with the ratchet 302.

[0031] In this embodiment: by setting a fastening bolt 1, after the fastening bolt 1 is connected to the locking component 3 through the cross slot 2, the fastening bolt 1 can be locked by the locking component 3, so that the fastening bolt 1 will not loosen due to wind and vibration, thereby improving the stability of the fastening bolt 1 in use.

[0032] Specifically, such as Figure 5 As shown, the mating component 4 includes a fastening turnbuckle 401. The inner walls of both ends of the fastening turnbuckle 401 are threadedly connected to the surface of the fastening bolt 1. Mounting grooves 402 are provided on both sides of the fastening turnbuckle 401, and guide rods 403 are fixedly connected to the inner walls of the mounting grooves 402.

[0033] Specifically, such as Figure 5 As shown, a second spring 404 is sleeved on the surface of the guide rod 403. One end of the second spring 404 near the inner wall of the mounting groove 402 is fixedly connected to the mounting groove 402. The other end of the second spring 404 is fixedly connected to a connecting block 405. The side of the connecting block 405 near the fixing plate 303 is fixedly connected to the fixing plate 303. A through hole 406 is opened on the front side of the connecting block 405. The through hole 406 is slidably connected to the guide rod 403.

[0034] Specifically, such as Figure 5 As shown, there are four connecting blocks 405, and stainless steel sheets 5 are fixedly connected to the surface of the connecting blocks 405. The stainless steel sheets 5 are slidably connected to the inner wall of the mounting groove 402.

[0035] In this embodiment: by setting the fastening turnbuckle 401, it is easy to connect with the fastening bolt 1; by setting the mounting groove 402, the connecting block 405 can be limited, so that the position of the connecting block 405 will not shift when sliding; by setting the guide rod 403, the position of the second spring 404 can be limited, so as to prevent the second spring 404 from bending when contracting; by setting the second spring 404, the second spring 404 can provide a rebound force for the connecting block 405, so as to prevent the connecting block 405 from sliding due to the lack of rebound force; by setting the connecting block 405, it is easy to connect with the locking assembly 3; by cooperating with the mounting groove 402, the sliding connection position of the locking assembly 3 is limited; by setting the stainless steel plate 5, the stainless steel plate 5 can protect the connecting block 405 and prevent the connecting block 405 from being damaged during long-term sliding.

[0036] Specifically, such as Figure 4 As shown, the surface of the pawl 306 is provided with a corrosion-resistant coating 6.

[0037] Specifically, such as Figure 4 As shown, there are four fixing blocks 304 in total, and each pair is a group of two. Protective sleeves 7 are fixedly connected to the surface of each of the four fixing blocks 304.

[0038] In this embodiment: by setting the corrosion-resistant coating 6, the corrosion-resistant coating 6 can protect the pawl 306 and prevent the pawl 306 from being corroded when it encounters rainy weather. By setting the protective sleeve 7, the protective sleeve 7 can protect the fixing block 304 and prevent the fixing block 304 from being damaged due to accidental contact with the pawl 306.

[0039] Specifically, such as Figure 3 As shown, each of the two fastening bolts 1 has a collar 8 fixedly connected to one end of each bolt away from the other. The inner wall of the collar 8 is fitted with a secondary ring 9, and there are two secondary rings 9 in total.

[0040] Specifically, such as Figure 1 , Figure 2 As shown, both secondary rings 9 are provided with cable wires 10 on their surfaces, and the surface of the cable wires 10 is provided with rubber sleeves 11.

[0041] In this embodiment: by setting the collar 8, the collar 8 and the secondary ring 9 can prevent the cable wire 10 from falling off during the installation of the high-strength wind-resistant cable fastening structure for the net frame tent. Furthermore, the cooperation between the cable wire 10 and the rubber sleeve 11 can effectively prevent friction and wear between the cable wire 10 and the metal parts. Under the strong tension of the cable wire 10, the stability of the high-strength wind-resistant cable fastening structure for the net frame tent can be improved.

[0042] Working principle: When installing the high-strength wind-resistant cable fastening structure for the mesh tent, the fastening bolt 1 can be threaded onto the fastening turnbuckle 401. Then, align the cross slot 2 at one end of the fastening bolt 1 with the cross block 301, and connect the cross block 301 to the cross slot 2. Then, rotate the fastening turnbuckle 401, causing it to tighten the cable wire 10 through its interaction with the fastening bolt 1. As the turnbuckle 401 rotates, it drives the connecting block 405 in the mounting slot 402 to rotate. When the connecting block 405 rotates, the fixing plate 303 rotates along with it. The rotation of the fixing plate 303 causes the pawl 306 to slide on the ratchet 302. With continued rotation, the fastening bolt 1 pushes the cross block 301, and... The cross block 301 and ratchet 302 push the fixing plate 303. After the fixing plate 303 is pushed, the connecting block 405 can be moved. When the connecting block 405 moves, the mounting groove 402 can limit the connecting block 405. The second spring 404 can be squeezed by the pushing of the connecting block 405. Under the rebound force of the second spring 404, the connecting block 405 will not slide in the mounting groove 402. Thus, the fixing plate 303, ratchet 302 and cross block 301 will not slide. Under the action of the guide rod 403, the second spring 404 will not bend when squeezed. After adjusting to the required tension, the rebound force of the first spring 305 will push the pawl 306 into the ratchet 302, so that the pawl 306 and the ratchet 302 are engaged, thereby completing the locking of the fastening bolt 1.

[0043] The above are merely preferred embodiments of the present utility model and are 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.
