Abstract
Description
Technical Field
[0001] This utility model relates to the field of bolt technology, and more specifically, to a bolt with an adjustable sliding head. Background Technology
[0002] Bolts are indispensable connecting components in mechanical engineering and construction. They consist of a head and a threaded cylinder (i.e., a shank) used to securely join two or more parts with through holes together. Their working principle relies on the friction between the thread and the mating part (such as a nut or a tapped hole) and the elastic deformation of the material itself to achieve the fastening effect.
[0003] During frequent installation and disassembly operations, the grooves on the bolt heads are prone to wear, a phenomenon known as stripping. Stripping prevents the screwdriver from accurately engaging the groove, making it difficult to apply sufficient torque to turn the bolt, thus making disassembly extremely difficult or even impossible. This not only increases the time cost of maintenance and repair but may also delay important maintenance work or emergency repairs due to the inability to loosen the bolt in time. Utility Model Content
[0004] In order to overcome the shortcomings of the prior art, the purpose of this utility model is to provide a bolt with adjustable sliding head.
[0005] An adjustable bolt with a sliding head includes a first screw, a head, a first connecting block, a slider, a second connecting block, a clamping assembly, and a second screw. The head is connected to the first screw, and the first connecting block and two second connecting blocks are connected to the outer wall of the head. The slider is slidably connected to the first connecting block, and the second connecting blocks are located on the front and rear sides of the slider. The clamping assembly is connected to the side of the second connecting blocks that are close to each other. The second screw is threadedly connected to the inside of the first screw, and the second screw extends from the bottom of the first screw.
[0006] As an improvement to the above solution, the clamping assembly includes a locking ball and an elastic element. The locking balls are slidably connected to the sides of the front and rear second connecting blocks that are close to each other. The locking balls are connected to the second connecting blocks by elastic elements. The front and rear sides of the slider have slots that are adapted to the locking balls.
[0007] As an improvement to the above solution, a handle is also included, with the handle attached to the slider.
[0008] As an improvement to the above solution, anti-slip pads are also included, with anti-slip pads connected to both the front and rear sides of the slider.
[0009] As an improvement to the above solution, an anti-slip ring is also included, with the bottom of the second screw connected to the anti-slip ring.
[0010] As an improvement to the above solution, a protective pad is also included, with a protective pad attached to the bottom of the head.
[0011] The beneficial effects of this utility model are as follows: This utility model is provided with a first connecting block, a slider, and a second connecting block. When it is necessary to remove this adjustable bolt and the groove at the head is stripped, the slider can be rotated by hand or tool, thereby enabling the adjustable bolt to be quickly and effectively removed from the installation position, reducing maintenance time, improving the maintenance efficiency of this adjustable bolt, and avoiding the inability to remove the adjustable bolt due to stripped groove. It is also provided with a handle, which can be used to rotate the slider. This is suitable for situations where the slider is too close to the installation position and the gripping area is insufficient, thus improving the applicability of this adjustable bolt.

[0017] The embodiments of this utility model will be described below with reference to the accompanying drawings.
[0018] A type of bolt with adjustable sliding head, such as Figures 1-4As shown, the assembly includes a first screw 1, a head 2, a first connecting block 3, a slider 4, a second connecting block 5, a clamping assembly, an anti-slip pad 8, a handle 9, a second screw 10, an anti-slip ring 11, and a protective pad 12. The head 2 is fixedly connected to the top of the first screw 1. One first connecting block 3 and two second connecting blocks 5 are fixedly connected to the outer wall of the head 2. The slider 4 is slidably connected to the first connecting block 3, which is located inside the slider 4. The two second connecting blocks 5 are located on the front and rear sides of the slider 4, respectively. Anti-slip pads 8 are fixedly connected to both the front and rear sides of the slider 4. The anti-slip pads 8 increase the friction between the hand or tool and the slider 4, preventing slippage when rotating the slider 4. The second connecting blocks 5 are mutually... A clamping assembly is connected to each side. A handle 9 is fixedly connected to the top of the slider 4. A second screw 10 is internally threaded to the first screw 1. The second screw 10 extends from the bottom of the first screw 1. An anti-slip ring 11 is fixedly connected to the bottom of the second screw 10. When the second screw 10 is rotated, it can increase the friction between the hand or tool and the second screw 10. It can also serve as a head and tail marker for the second screw 10. A protective pad 12 is fixedly connected to the bottom of the head 2. The protective pad 12 can prevent damage caused by local stress concentration to the designated position, prevent the nut or bolt from loosening on its own, increase the safety and stability of this adjustable bolt, and also provide waterproof and dustproof protection, improving the sealing performance of this adjustable bolt.
[0019] like Figure 2 and Figure 3 As shown, the clamping assembly includes a retaining bead 6 and an elastic element 7. The retaining bead 6 is slidably connected to the side of the front and rear second connecting blocks 5 that are close to each other. The elastic element 7 is fixedly connected between the retaining bead 6 and the second connecting block 5. The elastic element 7 is set as a helical spring. The front and rear sides of the slider 4 have slots that are adapted to the retaining bead 6. The clamping assembly can fix the slider 4 and prevent the slider 4 from sliding randomly, which would cause inconvenience in installation.
[0020] Initially, the retaining bead 6 is located in the retaining groove, and the elastic element 7 is in a compressed state. The first screw 1 does not contain the second screw 10. When using this adjustable bolt, first apply glue to the inside of the first screw 1. Before the glue takes effect, align the second screw 10 with the first screw 1. Pinch the anti-slip ring 11 to rotate the second screw 10 into the first screw 1. Under the action of the threads of the first screw 1 and the second screw 10, the second screw 10 slides upward along the internal threads of the first screw 1, thereby extending the first screw 1. This allows it to adapt to different installation environments and needs, eliminating the need to prepare bolts of different lengths for specific situations, thus improving work efficiency and facilitating maintenance. When the distance between the upper end of the first screw 1 and the lower end of the second screw 10 is the required length, stop rotating the second screw 10. After the glue takes effect, it can fix the first screw 1 and the second screw 10. Then, insert the extended adjustable bolt. When the adjustable bolt needs to be removed and the groove of the head 2 is stripped, pull the slider 4 to slide it away from the head 2 along the first connecting block 3. The slider 4 squeezes the retaining bead 6, which disengages from the groove. The elastic element 7 is compressed. Grasp the slider 4 with your hand or a tool and rotate it to quickly and effectively remove the adjustable bolt from the installation position, reducing maintenance time and improving the maintenance efficiency of the adjustable bolt. This avoids the adjustable bolt being unable to be removed due to stripped groove. When the slider 4 is too close to the installation position, hold the handle 9 with your hand or a tool and rotate the slider 4 through the handle 9. This is suitable for situations where the slider 4 is too close to the installation position, resulting in insufficient gripping area, thus improving the applicability of the adjustable bolt. After removing the stripped adjustable bolt, install the new adjustable bolt in the designated position, thereby completing the maintenance of the adjustable bolt.
