Description

Technical Field

[0001] This utility model belongs to the field of rebound device technology, specifically relating to a rebound device that features slow rebound, impact resistance, and comfortable operation. Background Technology

[0002] A rebound device is a device that uses springs, cylinders, hydraulic or damping mechanisms to return to its original position after being subjected to force. It is widely used in machining, mold manufacturing, stamping equipment, sports equipment and some daily necessities. Its main function is to automatically return the actuator to its initial position after the task is completed after triggering the force action.

[0003] However, existing rebounders still have the following problems in practical applications: most traditional rebounders rely on a single spring for rebound, which has a fast rebound speed and lacks effective buffering. It is easy to generate a large impact force at the moment of rebound, which can lead to equipment wear, loosening of parts, or even accidental injury to personnel; some rebounders have a relatively simple structure and the internal component connections are not stable enough. Under long-term repeated force, they are prone to loosening and displacement, which affects service life and stability; existing rebounders also have certain inconveniences in terms of installation and maintenance. Some assembly structures are not reasonably designed, resulting in complicated disassembly and assembly, long maintenance cycles, and increased use and maintenance costs.

[0004] Therefore, overcoming the shortcomings of the existing technology is an urgent problem to be solved in this technical field. Utility Model Content

Detailed Implementation

[0020] like Figures 1 to 4 As shown, a rebound device includes a base 10, on which a housing 20 is mounted. A tail rubber 30 is mounted at the inner rear end of the housing 20, and an inner core 40 is mounted at the inner front end of the housing 20. A tooth 50 is connected to the front end of the inner core 40, and a connecting hook 41 is provided at the rear end of the inner core 40. A hook line connecting part 31 is provided at the front end of the tail rubber 30. A return spring 60 is connected between the connecting hook 41 and the hook line connecting part 31. A locking hook line 32 adapted to the connecting hook 41 is connected inside the hook line connecting part 31. In use, when the user presses the tooth 50, the tooth 50 moves the inner core 40 backward, and the locking hook line 32 hooks the connecting hook 41. At the same time, the return spring 60 is compressed. When the tooth 50 is pressed again, the locking hook line 32 separates from the connecting hook 41, and the return spring 60 releases energy to push the inner core 40 back to its original position.

[0021] In practical implementation, the inner core 40 has a connecting post 42 at its front end. The connecting post 42 has an installation groove 421 inside, and a damping cylinder 70 is installed inside the installation groove 421. One end of the damping cylinder 70 has a cylinder connecting rod 71, and the end of the cylinder connecting rod 71 is connected to a top head 72. The inner core 40 has symmetrically opened inclined block slots 43 on both sides. Compression inclined blocks 44 are connected to the two inclined block slots 43 respectively. The two compression inclined blocks 44 are symmetrically connected to the two sides of the top head 72. In use, when the return spring 60 releases energy to push the inner core 40 forward, the compression inclined blocks 44 move inward along the inclined guide inside the outer shell 20 and simultaneously push the top head 72 to compress the damping cylinder 70, so that the damping cylinder 70 generates a damping effect, thereby slowing down and controlling the forward movement speed of the inner core 40, so that the tooth 50 can rebound slowly, preventing rapid ejection and impact, and improving the safety and stability of use.

[0022] In practical implementation, a fixing through hole 422 is provided on the front side of the connecting column 42. A fixing column 45 is connected in the fixing through hole 422. The fixing column 45 abuts against the end of the damping cylinder 70 away from the cylinder connecting rod 71, thereby fixing the damping cylinder 70 in the mounting through groove 421, ensuring the stability of the position of the damping cylinder 70 during operation, avoiding displacement or loosening. The structure is simple, the installation and operation are convenient, and the fixing effect is reliable.

[0023] In practical implementation, the tail adhesive 30 has a mounting groove 33 in the middle, the locking hook 32 has a mounting position 321 at the rear end, and the outer shell 20 has symmetrical mounting holes 21 on both rear sides. The mounting holes 21, the mounting groove 33, and the mounting position 321 are correspondingly arranged. The mounting holes 21, the mounting groove 33, and the mounting position 321 are connected to the mounting posts 80. The tail adhesive 30, the locking hook 32, and the outer shell 20 are reliably connected together through the mounting posts 80, ensuring that the position of each component is stable and the fit is tight during use. At the same time, the structure is simple, the installation is convenient, and the connection is firm.

[0024] In practical implementation, the rear end of the tooth head 50 is provided with a connecting screw groove 51, and the outer side of the connecting post 42 is provided with a connecting screw part 423 that is adapted to the connecting screw groove 51. The connecting post 42 is connected in the connecting screw groove 51. At the same time, the connecting screw part 423 and the connecting screw groove 51 are threadedly connected and fixed, so that the tooth head 50 is fixedly connected to the front end of the inner core 40, ensuring the stability of the tooth head 50 in position and reliable force during operation, while facilitating disassembly and replacement.

[0025] In practical implementation, the front end of the tooth head 50 is recessed with a mounting recess 52, in which a striking stone 53 is embedded. When in use, when an external force is applied to the striking stone 53, the striking stone 53 will transmit the force to the tooth head 50 and drive the inner core 40 to move accordingly, thereby triggering the cooperation action between the connecting hook 41 and the locking hook line 32, realizing the working process of the rebounder.

[0026] In practical implementation, the inner surface of the base 10 is provided with a mounting groove 11, and the inner sides of the mounting groove 11 are symmetrically provided with fixing slots 111. The lower sides of the outer shell 20 are symmetrically provided with fixing blocks 22. The outer shell 20 is slidably connected in the mounting groove 11. At the same time, the fixing blocks 22 are engaged with the fixing slots 111, so that the outer shell 20 is installed on the base 10, which is convenient for assembly and disassembly and can maintain structural stability during use.

[0027] In practical implementation, the inner surface of the base 10 is provided with an installation hole 12. During use, the base 10 can be screwed or snapped to the external support structure or installation component through the installation hole 12, thereby achieving a stable installation of the rebounder and facilitating disassembly or replacement according to usage requirements.

[0028] In summary, the base 10 is equipped with a housing 20. A tail rubber 30 is installed at the rear end of the housing 20, and an inner core 40 is installed at the front end. A toothed head 50 is connected to the front end of the inner core 40. A connecting hook 41 is provided at the rear end of the inner core 40. A hook wire connecting part 31 is provided at the front end of the tail rubber 30. A return spring 60 is connected between the connecting hook 41 and the hook wire connecting part 31. A locking hook wire 32 adapted to the connecting hook 41 is connected inside the hook wire connecting part 31. A connecting post 42 is provided at the front end of the inner core 40. An installation through groove 421 is provided inside the installation through groove 421. A damping cylinder 70 is installed, with a cylinder connecting rod 71 at one end. The end of the cylinder connecting rod 71 is connected to a top head 72. The inner core 40 has symmetrically opened inclined block slots 43 on both sides. Compression inclined blocks 44 are connected to the two inclined block slots 43 respectively. The two compression inclined blocks 44 are symmetrically connected to the two sides of the top head 72. The rebound device of this utility model, through the cooperation of the return spring, damping cylinder, top head and compression inclined blocks, enables the tooth head to slowly rebound after the force is released, thereby effectively reducing the rebound impact force and improving the safety and stability of use. At the same time, the structure is compact, the components are firmly connected, and the installation and maintenance are relatively convenient.
