Description

Technical Field

[0001] This utility model relates to the field of screw technology, and in particular to a novel screw mounting structure and screw assembly. Background Technology

[0002] The connection between the various modules of a mold usually requires high precision and high strength fixing. The new screw mounting structure and screw assembly can meet this requirement, ensuring that the mold will not deform or loosen due to stress during stamping, injection molding and other processes, thereby improving the service life of the mold and the quality of the produced products.

[0003] In existing technologies, after installation, the interaction between the serrated spring of the limiting component and the surrounding structure, as well as the engagement of the compression strip between the contact strip and the screw fixing groove, increases the resistance to screw loosening, thus achieving an anti-loosening function. When disassembly is required, the limiting component can be removed for convenient subsequent operations.

[0004] However, in actual use, when the tightening tool does not match the screw mounting structure, the operator needs to spend more effort to adjust the angle and force of the tool to make it compatible with the screw. This undoubtedly increases the difficulty and complexity of operation and reduces work efficiency. In response to the above problems, a new screw mounting structure and screw assembly are proposed. Utility Model Content

[0005] To overcome the above shortcomings, this utility model provides a novel screw mounting structure and screw assembly, aiming to improve the problem that some existing devices cannot adapt to tightening operations.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A novel screw mounting structure includes a nut, the outer top of which has a cavity, and the cavity is provided with multiple self-adaptive mechanisms.

[0008] The adaptive mechanism includes multiple limiting rods, with sliding blocks slidably connected to the outside of each limiting rod. A reset assembly is provided inside the cavity, and the outside of each limiting rod is fixedly connected to the inside of the cavity.

[0009] As a further description of the above technical solution:

[0010] The reset assembly includes a reset spring, the outside of which is disposed inside the cavity;

[0011] As a further description of the above technical solution:

[0012] A limiting ring is fixedly connected to the outside of the limiting rod, and the outside of the limiting ring is in contact with the outside of the sliding block;

[0013] As a further description of the above technical solution:

[0014] One end of the reset spring is fixedly connected to the inside of the cavity, and the other end of the reset spring is fixedly connected to the outside of the sliding block;

[0015] As a further description of the above technical solution:

[0016] A rubber ring is fixedly connected to the outer top of the nut, and the internal thread of the nut is connected to the outside of the screw body;

[0017] As a further description of the above technical solution:

[0018] The nut is externally rotatably connected to multiple locking rods, and the screw body has a locking groove on its exterior.

[0019] As a further description of the above technical solution:

[0020] A rubber pad is fixedly connected to the outer bottom end of the nut, and the outer side of the rubber pad is in contact with the outer side of the rubber ring;

[0021] As a further description of the above technical solution:

[0022] The outer side of the locking rod engages with the outer side of the locking groove, and the outer side of the rubber ring contacts the outer side of the screw body.

[0023] This utility model has the following beneficial effects:

[0024] 1. In this utility model, by placing the tool inside the cavity, the tool presses against the sliding block, which in turn presses against the return spring inside the cavity, allowing the sliding block to make close contact with the tool. This enables the nut to drive the screw body to tighten. The adaptive screw mounting structure and components can quickly fit with the tightening tool, eliminating the need for operators to spend a lot of time adjusting the tool angle and finding a suitable force point.

[0025] 2. In this utility model, after the screw body is tightened with the nut, the nut is rotated outside the screw body. Then, when the nut is tightened to the appropriate position, the locking rod is inserted so that it engages with the locking groove outside the screw body, thereby fixing the position of the nut and preventing the nut from stripping and falling off. The secondary fixing of the nut can avoid damage to the connection structure caused by the loosening of the nut. Attached Figure Description

[0032] 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.

[0033] Reference Figures 1 to 3 The present invention provides an embodiment of a novel screw mounting structure, comprising a nut 1. In the machining process, the threads, shape, and cavity 6 of the nut 1 are finely ground to achieve the industry standard for thread precision, ensuring a tight fit with the screw. The cavity 6 is precisely sized to provide a stable installation space for the adaptive mechanism. The nut 1 has a cavity 6 at its outer top end. The cavity 6 is cylindrical, and its depth and diameter are precisely designed according to the size and working requirements of the adaptive mechanism. Multiple adaptive mechanisms are set inside the cavity 6.

[0034] The adaptive mechanism includes multiple limiting rods 2, which provide sliding guides for the sliding block 3, allowing the sliding block 3 to slide only along the axial direction of the limiting rod 2. The sliding block 3 is slidably connected to the outside of the limiting rod 2, and the outside of the sliding block 3 is slidably connected to the limiting rod 2 through a through hole. Under the elastic force of the return spring 4 and external forces, it can slide up and down along the limiting rod 2. A reset assembly is installed inside the cavity 6, including a return spring 4. Spring steel ensures that the return spring 4 can withstand frequent compression and tension, and is not easily deformed after long-term use. One end of the return spring 4 is fixedly connected to the inside of the cavity 6, and the other end of the return spring 4 is fixedly connected to the outside of the sliding block 3. The outside of the return spring 4 is located inside the cavity 6. The outside of the limiting rod 2 is fixedly connected to the inside of the cavity 6. The outside of the limiting rod 2 is fixedly connected to the limiting ring 5. The outside of the limiting ring 5 is in contact with the outside of the sliding block 3. When the sliding block 3 slides along the limiting rod 2 to a specific position, the limiting ring 5 blocks the sliding block 3 from continuing to slide, preventing it from falling off the limiting rod 2. The outside of the limiting ring 5 is in contact with the outside of the sliding block 3.

[0035] Reference Figures 2 to 4 The internal thread of the nut 8 and the external thread of the screw body 7 are matched with each other with high precision, which can withstand large axial tensile force and torque. The screw body 7 is slender rod-shaped. Precisely machined threads are evenly distributed on the outer surface of the screw body 7. A rubber ring 12 is fixedly connected to the outer top of the nut 8. The internal thread of the nut 8 is connected to the outside of the screw body 7. Multiple locking rods 9 are rotatably connected to the outside of the nut 8. The locking rods 9 are rotated to the position aligned with the locking groove 10. The locking rods 9 are forcefully inserted into the locking groove 10, so that the outside of the locking rods 9 and the outside of the locking groove 10 are tightly engaged. The locking groove 10 is opened on the outside of the screw body 7. The shape of the locking groove 10 is generally rectangular. The depth and width are precisely designed according to the size of the locking rods 9 to ensure that the locking rods 9 can be tightly engaged in it, achieving reliable positioning and fastening.

[0036] A rubber pad 11 is fixedly connected to the outer bottom end of the nut 1. The function of the rubber pad 11 is to further enhance the buffering and sealing effect when the nut 1 and the nut 8 are engaged, while reducing the friction and wear between the nut 1 and the connected parts and protecting the surface of the connected parts. The outer side of the rubber pad 11 is in contact with the outer side of the rubber ring 12, the outer side of the locking rod 9 is engaged with the outer side of the locking groove 10, and the outer side of the rubber ring 12 is in contact with the outer side of the screw body 7.

[0037] Working principle: When the tool for tightening nut 1 is adaptive, by placing the tool inside the cavity 6, the tool presses against the sliding block 3. Under the action of the sliding block 3, the sliding block 3 presses against the return spring 4 inside the cavity 6, so that the sliding block 3 can make close contact with the tool, thereby tightening the nut 1 and the screw body 7. Because of the limit rod 2, the sliding block 3 can slide outside the limit rod 2, so that the sliding block 3 will not disengage.

[0038] After tightening the screw body 7 with the nut 1, the nut 8 is rotated outside the screw body 7. When the nut 8 is tightened to the appropriate position, the locking rod 9 is inserted, so that the locking rod 9 engages with the locking groove 10 on the outside of the screw body 7, thereby fixing the position of the nut 8 and preventing the nut 8 from stripping and falling off.

[0039] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
