Technical Field
[0001] This utility model relates to the field of screw structure technology, and in particular to a screw structure with high-strength threaded connection. Background Technology
[0002] In modern industrial production and machinery manufacturing, the screw, as a key component for mechanical connection and transmission, directly affects the stability, safety, and production efficiency of equipment operation. Traditional screw connection structures have many shortcomings in strength and stability, making it difficult to meet the current requirements of high-load and high-precision operations. When equipment is subjected to large pressure, tension, or is in a vibration environment, ordinary screw connections are prone to loosening and deformation, leading to connection failure and even safety accidents in severe cases. In addition, conventional screw fixing devices lack sufficient flexibility and versatility when dealing with parts of different sizes and shapes, requiring frequent equipment replacement or adjustment of installation methods, which increases production costs and reduces production efficiency. At the same time, the complex operation of screw fixing structures not only consumes a lot of manpower and time, reducing labor productivity, but may also cause quality problems due to operational errors. Therefore, developing a high-strength threaded connection screw structure to improve the strength and stability of screw connections, enhance versatility, and simplify operation procedures is of great practical significance for promoting efficient and safe industrial production.

[0009] As a further embodiment of this utility model: two openings are provided on one side of the inner cylinder, two grooves are provided around the inner cylinder, and the grooves around the inner cylinder and the grooves on the inner wall of the outer cylinder are respectively provided with internal threads, and the threaded interfaces fit together. Two threaded rods are respectively movably connected between the outer groove of the inner cylinder and the inner groove of the outer cylinder.

[0012] As a further embodiment of this utility model: the movable ring is fixedly connected to one side of the telescopic spring, and the movable ring and the telescopic spring are movably connected around the small cylinder.

The three pressure springs are respectively fixedly connected between the clamping plate and the clamping plate.
[0013] Compared with the prior art, this utility model provides a screw structure with high-strength threaded connection, which has the following beneficial effects:
[0014] 1. This high-strength threaded connection screw structure connects the threaded rod to other components via a screw base. A baffle, support base plate, and support corner blocks provide support and positioning. Clamping plates one and two can slide on the sliding base. A locking mechanism clamps the threaded rod between clamping plates one and two. A fixing mechanism, in conjunction with the screw base, can clamp and fix different parts. This ensures the threaded rod maintains an accurate position during operation, preventing wobbling or displacement. It allows for easy position adjustment to accommodate parts of different sizes, improving the structure's versatility and practicality. The operation is convenient and efficient, reducing labor intensity.
[0015] 2. This high-strength threaded connection screw structure, by rotating the threaded screw, causes the inner cylinder's circumference grooves and the inner wall grooves of the outer cylinder to match each other. The rotation of the threaded screw gradually squeezes the inner cylinder, reducing the size of the opening inside the inner cylinder, thus tightening and fixing the threaded rod body. Initially, when the threaded screw is not rotated, the limiting ring, outer cylinder, and inner cylinder can be moved to appropriate positions according to the fixing requirements of different parts. This satisfies the fixing requirements of parts of different sizes and shapes, improves the versatility of the fixing mechanism, and provides reliable fastening force during fixing, ensuring the stability of parts on the threaded rod body and reducing working errors and safety hazards caused by loosening.
[0016] 3. This high-strength threaded connection screw structure, by pushing the handle, allows the hollow cylinder, movable bar, limiting cylinder, and threaded screw to pass sequentially through clamping plate two and clamping plate one. The movable block moves between the rod and the movable ring, and the movable ring has a certain elastic displacement space under the action of the telescopic spring, causing one end of the movable bar to pop out and enter the opening on one side of clamping plate one, fixing the parts on one side of clamping plate one. At this time, rotating the nut rotator causes the threaded screw to move towards the handle and press against one side of clamping plate two. The three pressure springs between clamping plate one and clamping plate two are compressed, generating elastic force, so that clamping plate one and clamping plate two can tightly clamp the threaded rod body. Thus, it is ensured that the threaded rod body will not loosen or shift during operation, greatly enhancing the stability and reliability of the entire screw structure and ensuring smooth operation.
[0017] The parts of this device not covered herein are the same as or can be implemented using existing technologies. This utility model has a simple structure and is easy to operate. Attached Figure Description

For example, they can refer to a fixed connection or setting, a detachable connection or setting, or an integral connection or setting. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.
[0028] A high-strength threaded connection screw structure, such as Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 and Figure 6 As shown, it includes a threaded rod body 3, a screw base 2 fixedly connected to one side of the threaded rod body 3, a fixing mechanism 4 movably connected around the threaded rod body 3, a baffle 1 movably connected around one end of the threaded rod body 3, a supporting base plate 10 fixedly connected to the bottom of the baffle 1, a supporting corner block 11 fixedly connected to the bottom of the supporting base plate 10, and a supporting corner block 11 fixedly connected to one side of the baffle 1. A clamping plate 5 movably connected to one side of the threaded rod body 3.
[0029] A second clamping plate 6 is movably connected to one side of the threaded rod 3. A locking mechanism 7 is movably connected inside the first clamping plate 5 and the second clamping plate 6. A slider is provided at the bottom of the first clamping plate 5 and the second clamping plate 6. A groove base 9 is slidably connected to the bottom of the first clamping plate 5 and the second clamping plate 6. Side plates 8 are fixedly connected to both sides of the groove base 9. A guide rail is provided at the top of the support base plate 10, and the groove base 9 is slidably connected to the top of the support base plate 10.
[0030] During operation, the threaded rod 3 is connected to other components via the screw base 2. The baffle 1, support base plate 10, and support corner block 11 provide support and positioning. Clamping plate 5 and clamping plate 6 can slide on the sliding base 9. The locking mechanism 7 clamps the threaded rod 3 between clamping plate 5 and clamping plate 6. The fixing mechanism 4, in conjunction with the screw base 2, can clamp and fix different parts. As a result, the threaded rod 3 can maintain an accurate position during operation, avoiding shaking or displacement. It is convenient to adjust the position to adapt to parts of different sizes, improving the versatility and practicality of the structure. The operation process is convenient and efficient, reducing labor intensity.
[0031] To coordinate with the screw base 2 to clamp and fix the threaded rod body 3 for different parts, such as... Figure 2 and Figure 3As shown, the fixing mechanism 4 includes a limiting ring 401, an outer cylinder 402, a threaded rod 403, and an inner cylinder 404. The limiting ring 401 is movably connected to the circumference of the threaded rod 3. The outer cylinder 402 is fixedly connected to one side of the limiting ring 401, and two grooves are provided on the inner wall of the outer cylinder 402. The inner cylinder 404 is movably connected to the inside of the outer cylinder 402.
[0032] Furthermore, two openings are provided on one side of the inner cylinder 404, and two grooves are provided around the inner cylinder 404. The grooves around the inner cylinder 404 and the grooves on the inner wall of the outer cylinder 402 are respectively provided with internal threads, and the threaded interfaces match each other. Two threaded rods 403 are respectively movably connected between the outer groove of the inner cylinder 404 and the inner groove of the outer cylinder 402.
[0033] During operation, by rotating the threaded screw 403, the inner cylinder 404's grooves around its perimeter match the internal thread interface of the outer cylinder 402's inner wall groove. The rotation of the threaded screw 403 gradually squeezes the inner cylinder 404, reducing the size of the opening inside the inner cylinder 404 and thus tightening and fixing it to the threaded rod 3. Initially, when the threaded screw 403 is not rotated, the limiting ring 401, outer cylinder 402, and inner cylinder 404 can be moved to appropriate positions according to the fixing requirements of different parts. This satisfies the fixing requirements of parts of different sizes and shapes, improves the versatility of the fixing mechanism 4, and provides reliable fastening force during fixing, ensuring the stability of the parts on the threaded rod 3 and reducing working errors and safety hazards caused by loosening.
[0034] To ensure the stability of the threaded rod body 3, such as Figure 4 , Figure 5 and Figure 6 As shown, the locking mechanism 7 includes a handle 701, a threaded screw 702, a limiting cylinder 703, a hollow cylinder 704, a pressure spring 705, a nut rotator 706, a movable bar 707, a moving block 708, a movable ring 709, a telescopic spring 710, a large cylinder 711, a small cylinder 712, and a round rod 713. The threaded screw 702 is movably connected to the inside of the clamping plate 6, and the nut rotator 706 is movably connected to the circumference of the threaded screw 702.
[0035] Handle 701 is fixedly connected to one side of threaded screw 702, limiting cylinder 703 is fixedly connected to one side of threaded screw 702, and limiting cylinder 703 passes through clamp 5, hollow cylinder 704 is fixedly connected to one side of limiting cylinder 703, large cylinder 711 is fixedly connected to the inside of hollow cylinder 704, round rod 713 is fixedly connected to the inside of limiting cylinder 703, small cylinder 712 is fixedly connected to one side of large cylinder 711, and small cylinder 712 is fixedly connected to one side of round rod 713, and telescopic spring 710 is fixedly connected to one side of large cylinder 711.
[0036] The movable ring 709 is fixedly connected to one side of the telescopic spring 710, and the movable ring 709 and the telescopic spring 710 are movably connected to the periphery of the small cylinder 712. One end of the hollow cylinder 704 is movably connected to the periphery of the limiting cylinder 703. Four openings are respectively provided on one side of the clamping plate 5. One end of the four hollow cylinders 704 is movably connected to the inside of the openings of the clamping plate 5. The movable block 708 is fixedly connected to the bottom of the movable strip 707, and the four movable blocks 708 are respectively movably connected between the round rod 713 and the movable ring 709. The three pressure springs 705 are respectively fixedly connected between the clamping plate 5 and the clamping plate 6.
[0037] During operation, by pushing the handle 701, the hollow cylinder 704, movable bar 707, limiting cylinder 703, and threaded screw 702 pass sequentially through clamping plate 2 6 and clamping plate 1 5. The moving block 708 moves between the round rod 713 and the movable ring 709. The movable ring 709 has a certain elastic displacement space under the action of the telescopic spring 710, causing one end of the movable bar 707 to pop out and enter the opening on one side of clamping plate 1 5, thus fixing the parts on one side of clamping plate 1 5. At this time, rotating the nut rotator 706 causes the threaded screw 702 to move towards the handle 701 and press against one side of clamping plate 2 6. The three pressure springs 705 between clamping plate 1 5 and clamping plate 2 6 are compressed, generating elastic force, so that clamping plate 1 5 and clamping plate 2 6 can tightly clamp the threaded rod 3. This ensures that the threaded rod 3 will not loosen or shift during operation, greatly enhancing the stability and reliability of the entire screw structure and ensuring smooth operation.
[0038] Working principle: The threaded rod body 3 is connected to other components through the screw base 2. The baffle 1, the support base plate 10 and the support corner block 11 play a supporting and positioning role. The clamping plate 1 5 and the clamping plate 2 6 can slide on the sliding base 9.
[0039] Next, rotate the threaded screw 403. Since the grooves around the inner cylinder 404 and the internal thread interface of the groove on the inner wall of the outer cylinder 402 match each other, the rotation of the threaded screw 403 will gradually squeeze the inner cylinder 404, and the size of the opening inside the inner cylinder 404 will become smaller, so that it tightens and fixes the threaded rod body 3. In the initial stage when the threaded screw 403 is not rotated, the limiting ring 401, the outer cylinder 402 and the inner cylinder 404 can be moved to a suitable position according to the fixing requirements of different parts.
[0040] Finally, push the handle 701 so that the hollow cylinder 704, movable bar 707, limiting cylinder 703 and threaded screw 702 pass through clamping plate 2 6 and clamping plate 1 5 in sequence. The moving block 708 moves between the round rod 713 and the movable ring 709. The movable ring 709 has a certain elastic displacement space under the action of the telescopic spring 710, so that one end of the movable bar 707 pops out and enters the opening on one side of clamping plate 1 5, fixing the parts on one side of clamping plate 1 5. At this time, rotate the nut rotator 706 to move the threaded screw 702 towards the handle 701 and press it against one side of clamping plate 2 6. The three pressure springs 705 between clamping plate 1 5 and clamping plate 2 6 are compressed and generate elastic force, so that clamping plate 1 5 and clamping plate 2 6 can tightly clamp the threaded rod 3.
[0041] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
