Description

Technical Field

[0001] This utility model relates to the field of double-ended screw technology, and in particular to an impact-resistant double-ended screw. Background Technology

[0002] Double-ended studs, also widely known as double-ended screws or double-ended bolts, are connecting elements that play a crucial role in mechanical engineering, specifically designed to achieve secure connections between machinery. Their core feature is the precision-machined threads at both ends. This unique design allows double-ended studs to flexibly adapt to various complex connection requirements, ensuring tight and reliable connections between mechanical components. Whether in heavy machinery, precision instrument assembly, or various industrial manufacturing processes, double-ended studs have become an indispensable fastener due to their superior connection performance and wide applicability.

[0003] Existing double-ended screw designs are generally one-piece molded, with a fixed and non-adjustable length. This limits the flexibility of double-ended screws in different application scenarios, especially when facing varying length requirements, where traditional double-ended screws cannot perfectly fit, thus weakening their wide adaptability. To meet diverse length requirements, it is necessary to prepare products in multiple specifications, which not only increases costs but also affects efficiency and convenience of use. Utility Model Content

[0004] In view of the shortcomings of the existing technology, this utility model provides an impact-resistant double-ended screw.

[0005] An embodiment of this utility model provides an impact-resistant double-ended screw, comprising:

[0006] A sleeve, both ends of which are connected to threaded rods;

[0007] An adjusting assembly includes a fixed block and two rectangular rods. The fixed block is fixedly installed inside a sleeve. Rotating columns are rotatably connected to both sides of the fixed block. The two rectangular rods are respectively fixedly installed on the two rotating columns. A rectangular hole is provided on the inner side of the threaded rod, and the rectangular rod is slidably installed in the rectangular hole on the same side.

[0008] Limiting components are provided on both sides of the rotating column, and the limiting components are used to limit the threaded rod.

[0009] Furthermore, the limiting component includes a locking block, a pressure rod, a transmission rod, and a spring. The pressure rod is slidably disposed through the sleeve. Both the locking block and the pressure rod are provided with mounting grooves. A round rod is fixedly disposed in each mounting groove. Both ends of the transmission rod are provided with movable holes. The two round rods are respectively disposed through the two movable holes. Two side plates are fixedly disposed inside the sleeve. A shaft is fixedly disposed between the two side plates. The shaft is rotatably connected through the transmission rod. Both ends of the spring are respectively fixedly disposed on the locking block and the inner side of the sleeve.

[0010] Furthermore, internal threads are provided on the inner sides of both ends of the sleeve, and the threaded rod is threadedly connected to the inner side of the sleeve.

[0011] Furthermore, a guide hole is provided on the card block, and a guide rod is slidably disposed in the guide hole, with the outer end of the guide rod fixedly disposed on the inner side of the sleeve.

[0013] Furthermore, a pressure block is fixedly provided at the outer end of the pressure rod.

[0014] Compared with the prior art, the present invention has the following beneficial effects:

[0015] 1. A sleeve is provided, and the threaded rods on both sides can rotate within the two ends of the sleeve to adjust their position, thereby adjusting the length of the threaded rod extension to meet different length requirements and increasing adaptability.

[0016] 2. An adjustment component and a limiting component are provided. Pressing the two pressure blocks on the same side inwards simultaneously will pull the two locking blocks outwards to separate them from the locking holes, allowing the threaded rod to rotate freely and adjust its position. After adjusting to the ideal position, simply release the two pressure blocks to reset the two locking blocks and lock them into the locking holes at the current position, thus limiting and fixing the threaded rod. This ensures the overall stability during use, and the operation is simple, convenient, and efficient.

[0017] In summary, this utility model features a sleeve that allows for adjustment of the threaded rod's extension length to accommodate different length requirements, thus increasing its adaptability.

Detailed Implementation

[0023] The technical solution of this utility model will be further described below with reference to the accompanying drawings and embodiments.

[0024] like Figures 1-4 As shown, this utility model embodiment proposes an impact-resistant double-ended screw, comprising:

[0025] Sleeve 1, both ends of sleeve 1 are provided with internal threads, and both ends of sleeve 1 are connected to threaded rods 2. The threaded rods 2 are threaded to the inner side of sleeve 1, so that the threaded rods 2 can rotate inside sleeve 1 to adjust their position, thereby adjusting the length of the threaded rods 2 to adapt to different needs.

[0026] The adjustment assembly includes a fixed block 3 and two rectangular rods 5. The fixed block 3 is fixedly installed inside the sleeve 1. Rotating columns 4 are rotatably connected to both sides of the fixed block 3. The two rectangular rods 5 are respectively fixedly installed on the two rotating columns 4. A rectangular hole 6 is provided on the inner side of the threaded rod 2. The rectangular rod 5 is slidably installed in the rectangular hole 6 on the same side, so that the rectangular rod 5 can slide in the rectangular hole 6.

[0027] Limiting components are provided on both sides of the rotating column 4. The limiting components are used to limit the threaded rod 2. The limiting components include a locking block 7, a pressure rod 8, a transmission rod 10, and a spring 16. A guide hole 15 is provided on the locking block 7. A guide rod 14 is slidably arranged in the guide hole 15. The outer end of the guide rod 14 is fixedly arranged on the inner side of the sleeve 1. The guide rod 14 is used to guide and support the locking block 7.

[0028] The rotating column 4 is provided with several locking holes 18, which are evenly distributed around the circumference. The locking block 7 is configured to cooperate with the locking holes 18, so that the locking block 7 can be locked into the locking hole 18.

[0029] The pressure rod 8 is slidably disposed through the sleeve 1, and a pressure block 17 is fixedly disposed at the outer end of the pressure rod 8. The pressure block 17 can easily press the pressure rod 8 inward. Both the locking block 7 and the pressure rod 8 are provided with mounting grooves, and round rods 9 are fixedly disposed in the mounting grooves. Both ends of the transmission rod 10 are provided with movable holes 11. The two round rods 9 are respectively disposed through the two movable holes 11, so that the round rods 9 can move in the movable holes 11 on the same side, thereby preventing the transmission rod 10 from getting stuck.

[0030] Two side plates 12 are fixedly installed inside the sleeve 1, and a shaft 13 is fixedly installed between the two side plates 12. The shaft 13 passes through the transmission rod 10 and is rotatably connected, so that the transmission rod 10 can rotate through the shaft 13. The two ends of the spring 16 are respectively fixedly installed on the locking block 7 and the inner side of the sleeve 1, so that the locking block 7 and the sleeve 1 are elastically connected. The guide rod 14 passes through the spring 16 and is movably installed to ensure the stability of the spring 16.

[0031] The detailed working process of this utility model is as follows:

[0032] 1. When making adjustments, first, press the two pressure blocks 17 on the same side inwards simultaneously. The corresponding pressure rods 8 apply pressure to the two transmission rods 10. The transmission rods 10 then pull the two locking blocks 7 outwards through the action of the shaft 13, while compressing the corresponding springs 16, so that the locking blocks 7 disengage from the original locking holes 18. At this time, the user can freely rotate the threaded rod 2 on that side to adjust the position and thus adjust the length of the threaded rod 2 extending outwards.

[0033] 2. During the rotation of the threaded rod 2, the rotating column 4 on the same side is driven to rotate synchronously through the connected rectangular rod 5. When the threaded rod 2 is adjusted to the ideal position, simply release the two pressure blocks 17, causing the two locking blocks 7 to move inward and reset under the action of the spring force 16. They then lock into the locking holes 18 at the current position, fixing the rotating column 4. The threaded rod 2 on the same side is indirectly fixed through the rectangular rod 5, thus ensuring the overall stability during use. It is worth noting that the threaded rods 2 on both sides of the equipment follow the same adjustment process, and the operation is simple, convenient, and efficient.

[0034] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of this utility model without departing from the spirit and scope of the technical solutions of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
