Description

Technical Field

[0001] The utility model relates to the technical field of middle hexagonal screws, in particular to a middle hexagonal double-head screw. Background Art

[0002] The hexagonal stud screw is an innovative design with two different types of screw heads, usually one at one end of the screw and the other at the other end. Its structure includes a screw, a standard screw head and another type of screw head. This design gives the stud screw versatility and makes it suitable for different tools such as screwdrivers, wrenches or hexagonal wrenches. The body of the stud screw is a slender screw, usually made of metal, with threads on the surface of the screw to provide additional grip when screwing into the material. During use, the unique design of the hexagonal stud screw saves time and cost, especially for large-scale assembly. Line and high-efficiency working occasions, but in the current hexagonal double-head screws, during use, since the two thread grooves are arranged on the same rod body, this means that no matter which end of the thread groove is rotated, the thread groove of the other end will be affected, which leads to mutual restriction between the two thread heads, that is, when one of the heads is tightened or loosened, the other head will also move accordingly, and in some complex working scenarios, different torques or forces need to be applied to different ends in order to assemble or disassemble according to different needs, but the double-head screws are difficult to perform such tasks due to the limitation of the mutual influence of the two ends.

DETAILED DESCRIPTION

[0017] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0018] See also Figure 1-4 The utility model provides an embodiment: a hexagonal double-head screw, comprising a main hexagonal head 1 and a secondary hexagonal head 2 arranged at the top of the main hexagonal head 1, an anti-slip rotation connector 7 is arranged between the opposite ends of the main hexagonal head 1 and the secondary hexagonal head 2, a second anti-loosening disk 5 and a first anti-loosening disk 201 are respectively installed at the relatively far ends of the main hexagonal head 1 and the secondary hexagonal head 2, an upper screw 4 and a lower screw 3 are respectively installed at the top of the first anti-loosening disk 201 and the bottom of the second anti-loosening disk 5, and the lengths of the lower screw 3 and the upper screw 4 are both 5cm to 20cm;

[0019] The lower screw 3, the second anti-loosening plate 5, the main middle hexagonal head 1, the secondary middle hexagonal head 2 and the upper screw 4 form an integrated rod body screw structure, that is, the lower screw 3 and the upper screw 4 can rotate together under the drive of the wrench, and the two maintain the same installation torque;

[0020] A right-angle tongue plate 10 is slidably installed at one end of the main middle hexagon head 1, and an elastic reset structure 11 for forcing the right-angle tongue plate 10 to move upward is provided at the top of the second anti-loosening disk 5, and a rectangular column docking structure is provided between the top of the right-angle tongue plate 10 and the bottom of the first anti-loosening disk 201, and a shifting block 6 for pulling the right-angle tongue plate 10 and the rectangular column docking structure is provided on the outer wall of one side of the main middle hexagon head 1. When the user needs to rotate the lower screw 3 and the upper screw 4 respectively and connect the load, the rectangular column docking structure is separated by the shifting block 6, and then the secondary middle hexagon head 2 and the main middle hexagon head 1 can be connected by the anti-slip rotation connector 7 and rotate relative to each other, that is, the lower screw 3 and the upper screw 4 can apply different screwing torques to the load;

[0021] The anti-dropping rotating connecting member 7 comprises a multi-lip ring sleeve 702 fixed to the top of the main middle hexagonal head 1, and a support sleeve 701 rotatably mounted inside the multi-lip ring sleeve 702, the top of the support sleeve 701 is fixedly connected to the bottom end of the secondary middle hexagonal head 2;

[0022] When the main hexagonal head 1 and the secondary hexagonal head 2 rotate relative to each other, the support sleeve 701 and the multi-lip ring sleeve 702 make the lower screw 3 and the upper screw 4 more secure during the connection and rotation process, reducing the possibility of loosening and shaking of the connection part, especially in an environment that needs to withstand vibration or external force impact, effectively preventing accidental loosening of the screws and improving the reliability of the connection;

[0023] The rectangular column docking structure is composed of a rectangular hollow square column 8 and a rectangular solid column 9. The rectangular hollow square column 8 and the rectangular solid column 9 are both made of aluminum alloy. Aluminum alloy is a relatively light and strong material with a low density. Therefore, it is used to manufacture the rectangular hollow square column 8 and the rectangular solid column 9 to effectively reduce the weight of the overall structure of the stud screw.

[0024] The shift block 6 includes a rectangular slide groove 601 arranged on the outer wall of one side of the main middle hexagonal head 1, and a slide button 602 slidably installed inside the rectangular slide groove 601. One end of the slide button 602 extends to the inside of the main middle hexagonal head 1 and is fixedly connected to the outer wall of one side of the right-angle tongue plate 10. When it is necessary to release the connection between the main middle hexagonal head 1 and the secondary middle hexagonal head 2, the staff slides the slide button 602 so that the slide button 602 drives the right-angle tongue plate 10 and the rectangular solid column 9 to move downward. In this process, the rectangular slide groove 601 serves as a sliding guide for the slide button 602.

[0025] The rectangular hollow square column 8 is fixed at the center position of the bottom end of the first anti-loosening plate 201, and the rectangular solid column 9 is fixed at the center position of the top end of the right-angle tongue plate 10. The top end of the rectangular solid column 9 extends to the inside of the rectangular hollow square column 8 and is slidably connected with the rectangular hollow square column 8.

[0026] The elastic reset structure 11 is composed of guide posts and coil springs. Four guide posts are fixed at equal intervals on the top of the second anti-loosening disk 5. The top of the guide post passes through the outside of the right-angle tongue plate 10. The coil spring is mounted on the guide post. The top of the coil spring abuts against the bottom end of the right-angle tongue plate 10. When the coil spring in the elastic reset structure 11 is in a compressed state, the rectangular hollow square column 8 and the rectangular solid column 9 are separated. The staff can independently rotate the main center hexagonal head 1 or the secondary center hexagonal head 2 to make the lower screw 3 and the upper screw 4 rotate separately. If a threaded head needs to be repaired or replaced, the user can handle one of the heads relatively independently without affecting the state of the other head too much, thereby reducing the difficulty and cost of maintenance.

[0027] When the embodiment of the present application is in use, the staff can first actively screw the upper screw 4 and the lower screw 3 on the two ends of the double-headed screw to the connection point through a wrench. At this time, since the second anti-loosening plate 5, the first anti-loosening plate 201 and the secondary middle hexagonal head 2 and the main middle hexagonal head 1 are connected through the rectangular hollow square column 8 and the rectangular solid column 9, the lower screw 3, the second anti-loosening plate 5, the main middle hexagonal head 1, the secondary middle hexagonal head 2 and the upper screw 4 form an integrated rod body screw structure, that is, the lower screw 3 and the upper screw 4 can rotate together under the drive of the wrench, and the two maintain the same installation torque. When the user needs to make the lower screw 3 and the upper screw 4 rotate separately and connect the load, the staff manually dials the dial block 6, so that the dial block 6 drives the right-angle tongue plate 10 and the rectangular solid column 9 to move downward until the rectangular solid The column 9 withdraws to the outside of the rectangular hollow square column 8. At this time, the rectangular solid column 9 and the rectangular hollow square column 8 are no longer connected, and the elastic reset structure 11 is compressed and deformed by the right-angle tongue plate 10, so that the secondary hexagonal head 2 and the main hexagonal head 1 can be connected through the anti-slip rotation connector 7 and rotate relative to each other, that is, the lower screw 3 and the upper screw 4 can apply different screwing torques to the load. The design of the double-headed screw through the anti-slip rotation connector 7 and the rectangular column docking structure is not only suitable for scenarios where the two ends need to be operated independently, but also can cope with some tasks that require the two threaded heads to work together through an overall connection. That is, if a threaded head needs to be repaired or replaced, the user can handle one of the heads relatively independently, reducing the mutual constraints between the two threaded heads and will not affect the state of the other head too much.
