Description

Technical Field

[0001] The utility model relates to the technical field of screws, in particular to a handle screw. Background Art

[0002] A screw is a general term for fasteners. A screw is a tool that uses the physical and mathematical principles of the inclined plane circular rotation and friction of an object to gradually fasten the parts of a utensil. A drawer is a pull-out box used to store items in furniture such as tables and cabinets. It has a bottom but no lid and can be pushed and pulled freely. To facilitate the use of furniture such as drawers and wardrobes, a handle is usually installed on one side of them.

[0003] However, the current drawer handle is a long rod with screw threads at one end. A matching thread is provided inside the drawer, and the long rod is directly rotated and installed inside the drawer. Since no fixing screw or other fixing device is used, the long rod handle is likely to become loose due to friction and rotation during daily use, resulting in the problem of insufficient firm installation, which causes the long rod handle to be prone to shaking or falling. Therefore, this application provides a handle screw to meet the requirements. Summary of the Utility Model

[0004] The technical problem to be solved by the utility model is to provide a handle screw to solve the problem that when the long rod is directly rotated and installed inside the drawer, since no fixing screw or other fixing device is used, the long rod handle is likely to become loose due to friction and rotation during daily use, resulting in the long rod handle being prone to shaking or falling.

[0005] To solve the above technical problem, the utility model provides the following technical solutions:

[0006] A handle screw includes a ball head rod that movably penetrates through the inside of a drawer body, and includes the drawer body. An installation groove is provided inside the drawer body. The ball head rod movably penetrates through the inside of the drawer body. One end of the ball head rod is threadedly connected with a hexagonal nut. A push rod movably penetrates through the inside of the ball head rod. A raised piece is provided on the outer wall of the push rod, and a first spring is fixedly connected to one side of the raised piece. An activity groove is provided on the inner wall of the ball head rod. The other end of the first spring is fixedly connected to the inner wall of the activity groove. A clamping groove is provided at one end of the push rod. Two contact plates are rotatably connected to both sides of the ball head rod. The contact plates are L-shaped. The raised ends of the contact plates are rotatably connected inside the ball head rod, and the raised ends are arranged at the recessed parts on the outer wall of the clamping groove. A round rod is fixedly installed at one end of the push rod. A second spring is provided on the outer wall of the round rod. One end of the second spring is fixedly installed on the push rod. A circular groove for the round rod to move is provided inside the ball head rod. A contact ring is fixedly installed on one side of the hexagonal nut. One end of the contact plate is in contact with the inner wall of the contact ring. A pressing ball is fixedly installed at one end of the ball head rod. A matching groove for placing the contact plate is provided on the outer wall of the ball head rod.

[0007] Preferably, a blocking disc is fixedly installed on the outer wall of the ball head rod.

[0008] Preferably, one side of the blocking disc is in contact with one side of the drawer body, and an anti-slip gasket is provided on one side of the blocking disc.

[0009] Preferably, an elastic piece is movably clamped on one side of the hexagonal nut, and one side of the elastic piece is in contact with the inner wall of the installation groove.

[0010] Preferably, a covering piece is threadedly connected to one end of the ball head rod, and a cylindrical protrusion is provided on the surface of the covering piece.

[0011] Preferably, one side of the covering piece is in contact with the inner wall of the drawer body.

[0012] Preferably, a recessed groove is provided on one side of the pressing ball.

[0013] Preferably, an anti-slip washer is provided on one side of the covering piece.

[0014] Compared with the prior art, the present utility model has at least the following beneficial effects:

[0015] In the above solution, by providing the abutting plates, the two abutting plates abut against the inner wall of the abutting ring. Since the frictional force between one end of the abutting plate and the inner wall of the abutting ring is relatively large, the relative displacement between the abutting ring and the abutting plate is not likely to occur. As a result, the installed hexagonal nut and the abutting ring are not likely to deflect in angle, and the spherical end of the ball head rod is not likely to deflect due to the frictional force, thereby avoiding the relative angular deflection between one end of the ball head rod and the hexagonal nut, maintaining a stable connection and increasing the reliability of the connection.

[0016] By providing an anti-slip gasket on one side of the blocking disc, the frictional force between the blocking disc and the hexagonal nut is relatively large, and the relative rotation between the ball head rod and the drawer body is not likely to occur. Thus, when a frictional force is applied to one end of the ball head rod during subsequent use, the ball head rod is prevented from rotating, and the disconnection between the ball head rod and the hexagonal nut is avoided.

[0017] By providing the elastic piece, one side of the elastic piece is in contact with the inner wall of the installation groove. The elastic piece is made of rubber with a relatively large surface frictional force. As a result, the hexagonal nut and the elastic piece are not likely to rotate relative to the installation groove of the drawer body, and the relative rotation between the ball head rod and the hexagonal nut is not likely to occur and cause loosening.

[0018] By providing the anti-slip washer on one side of the covering piece, it not only plays a role in preventing the covering piece and the ball head rod from rotating, but also dust-proofs the installation groove, preventing more impurities from entering the interior of the installation groove. By providing the concave groove on one side of the pressing ball, it better conforms to the arc of the user's finger, thus facilitating the application of pressure when pushing the push rod.

[0030] Such as Figures 1-4As shown, an embodiment of the present utility model provides a handle screw, which includes a ball head rod 2 movably penetrating through the inside of a drawer body 1, and includes the drawer body 1. An installation groove is formed inside the drawer body 1. The ball head rod 2 movably penetrates through the inside of the drawer body 1. One end of the ball head rod 2 is threadedly connected with a hexagonal nut 4. A push rod 6 movably penetrates through the inside of the ball head rod 2. A raised piece is arranged on the outer wall of the push rod 6, and a first spring 7 is fixedly connected to one side of the raised piece. An activity groove 8 is formed inside the wall of the ball head rod 2. The other end of the first spring 7 is fixedly connected to the inner wall of the activity groove 8. A clamping groove 9 is formed at one end of the push rod 6. Two contact plates 10 are rotatably connected to both sides of the ball head rod 2. The contact plates 10 are L-shaped. The raised ends of the contact plates 10 are rotatably connected inside the ball head rod 2, and the raised ends are arranged at the recessed parts on the outer wall of the clamping groove 9. A round rod 11 is fixedly installed at one end of the push rod 6. A second spring 12 is arranged on the outer wall of the round rod 11. One end of the second spring 12 is fixedly installed on the push rod 6. A circular groove 13 for the movement of the round rod 11 is formed inside the ball head rod 2. A contact ring 16 is fixedly installed on one side of the hexagonal nut 4. One end of the contact plate 10 is in contact with the inner wall of the contact ring 16. A pressing ball 15 is fixedly installed at one end of the ball head rod 2. A fitting groove for placing the contact plate 10 is formed on the outer wall of the ball head rod 2.

[0031] First, press the pressing ball 15 inward, causing the push rod 6 to move in the direction of one end of the circular groove 13. While the raised piece moves inside the movable groove 8, it squeezes the first spring 7. While the push rod 6 drives the round rod 11 to move inside the circular groove 13, one end of the push rod 6 squeezes the second spring 12. Due to the movement of the push rod 6, the position of the clamping groove 9 moves, thereby pushing the raised end of the contact plate 10. Since the contact plate 10 is rotatably connected inside the ball head rod 2, and the ball head rod 2 is a symmetric structure of left and right halves, after being injection molded separately and then welded together. When the raised end of the contact plate 10 receives a thrust, it will drive the contact plate 10 to rotate around its own connecting shaft, so that the contact plate 10 fits into the mating groove on the outer wall of the ball head rod 2. At this time, pass the ball head rod 2 through the inside of the drawer body 1, keep pressing the pressing ball 15, so that the contact plate 10 is located inside the mating groove, and then rotate the hexagonal nut 4 from one end of the circular groove 13, gradually install the hexagonal nut 4 at one end of the ball head rod 2, and then release the pressing ball 15. At this time, the first spring 7 and the second spring 12 rebound, driving the push rod 6 to move away from one end of the circular groove 13. Furthermore, when the clamping groove 9 moves, the other side contacts and applies a thrust to the raised end of the contact plate 10, driving one end of the contact plate 10 to tilt up. The end of the contact plate 10 away from its own connecting shaft contacts the inner wall of the contact ring 16. By setting the contact plate 10, the two contact plates 10 abut against the inner wall of the contact ring 16. Due to the large friction between one end of the contact plate 10 and the inner wall of the contact ring 16, it is not easy for the contact ring 16 and the contact plate 10 to have relative displacement, so that the installed hexagonal nut 4 and the contact ring 16 are not easy to deflect in angle, and it is not easy for the spherical end of the ball head rod 2 to deflect due to friction, thereby avoiding relative angular deflection between one end of the ball head rod 2 and the hexagonal nut 4, maintaining stable connection and increasing the reliability of the connection.

[0032] As Figures 1-4 shown, a blocking disk 3 is fixedly installed on the outer wall of the ball head rod 2. One side of the blocking disk 3 is in contact with one side of the drawer body 1. A non-slip gasket is arranged on one side of the blocking disk 3. One side of the hexagonal nut 4 is movably clamped with an elastic piece 5. One side of the elastic piece 5 is in contact with the inner wall of the installation groove. One end of the ball head rod 2 is threadedly connected with a covering piece 14. The surface of the covering piece 14 has a cylindrical protrusion. One side of the covering piece 14 is in contact with the inner wall of the drawer body 1. A concave groove is formed on one side of the pressing ball 15. A non-slip washer is arranged on one side of the covering piece 14.

[0033] During the installation of the ball head rod 2 and the hexagon nut 4, the ball head rod 2 drives the blocking disc 3 to move to one side of the drawer body 1. Since an anti-slip gasket is provided on one side of the blocking disc 3, the frictional force between the blocking disc 3 and the hexagon nut 4 is relatively large. When the ball head rod 2 penetrates the inside of the drawer body 1, relative rotation between the ball head rod 2 and the drawer body 1 is not likely to occur, thereby avoiding the rotation of the ball head rod 2 caused by applying a frictional force to one end of the ball head rod 2 during subsequent use and preventing the disconnection of the ball head rod 2 from the hexagon nut 4. When rotating the hexagon nut 4 to install it at one end of the ball head rod 2, first stretch the elastic piece 5 with elasticity to generate deformation, and the elastic piece 5 restores its elastic deformation and is fixed on the outer wall of the hexagon nut 4. When installing the hexagon nut 4 at one end of the ball head rod 2, one side of the elastic piece 5 is in contact with the inner wall of the installation groove. The elastic piece 5 is made of rubber and has a relatively large surface frictional force, so that relative rotation between the hexagon nut 4 and the elastic piece 5 and the installation groove of the drawer body 1 is not likely to occur, and thus relative rotation and loosening between the ball head rod 2 and the hexagon nut 4 are not likely to occur. After the ball head rod 2 and the hexagon nut 4 are installed, pinch the protrusion at one end of the cover plate 14 and rotate the cover plate 14 to fix it at one end of the ball head rod 2. The anti-slip washer on one side of the cover plate 14 contacts the inner wall of the drawer body 1, which not only plays a role in preventing the rotation of the cover plate 14 and the ball head rod 2, but also dust-proofs the installation groove to prevent more impurities from entering the inside of the installation groove. By setting the concave groove on one side of the pressing ball 15, it better fits the arc of the user's finger, making it easier to apply pressure when pushing the push rod 6.

[0034] The technical solution provided by the utility model first presses the pressing ball 15 inwardly, so that the pushing rod 6 moves in the direction of one end of the circular groove 13, and the raised piece squeezes the spring 1 7 while moving inside the movable groove 8. The pushing rod 6 drives the round rod 11 to move inside the circular groove 13, and one end of the pushing rod 6 squeezes the spring 2 12. Due to the movement of the pushing rod 6, the position of the positioning groove 9 moves, thereby pushing the raised end of the contact plate 10. Since the contact plate 10 is rotatably connected to the inside of the ball head rod 2, when the raised end of the contact plate 10 is subjected to thrust, it will drive the contact plate 10 to rotate around its own connecting axis, so that the contact plate 10 fits into the matching groove on the outer wall of the ball head rod 2. At this time, the ball head rod 2 passes through the inside of the drawer body 1, and the ball head rod 2 drives the blocking plate 3 to move to one side of the drawer body 1. Since an anti-slip gasket is provided on one side of the blocking plate 3, the friction between the blocking plate 3 and the hexagonal nut 4 is relatively large, and the ball head rod 2 and The drawer bodies 1 are not prone to relative rotation. Keep pressing the pressing ball 15 so that the contact plate 10 is located inside the matching groove, and the elastic elastic sheet 5 is pulled to produce deformation. The elastic sheet 5 restores its elastic deformation and is fixed to the outer wall of the hexagonal nut 4. Then, the hexagonal nut 4 is rotated from one end of the circular groove 13, and the hexagonal nut 4 is gradually installed at one end of the ball head rod 2. One side of the elastic sheet 5 contacts the inner wall of the installation groove. Then, the pressing ball 15 is released. At this time, the spring 1 7 and the spring 2 12 rebound, driving the push rod 6 to move toward the end away from the circular groove 13. Then, when the positioning groove 9 moves, the other side contacts and applies a thrust to the raised end of the contact plate 10, driving one end of the contact plate 10 to tilt up. The end of the contact plate 10 away from its own connecting shaft contacts the inner wall of the contact ring 16. Pinch the protrusion at one end of the covering sheet 14, rotate the covering sheet 14 to fix it to one end of the ball head rod 2, and the anti-slip gasket on one side of the covering sheet 14 contacts the inner wall of the drawer body 1.

[0035] The present invention covers any substitution, modification, equivalent method and scheme made on the essence and scope of the present invention. In order to make the public have a thorough understanding of the present invention, the specific details are described in detail in the above preferred embodiments of the present invention, and those skilled in the art can fully understand the present invention without the description of these details.

[0036] The above are only preferred implementations of the present invention. It should be pointed out that, for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the principle of the present invention. These improvements and modifications should also be regarded as the protection scope of the present invention.
