Description

Technical Field

[0001] This utility model belongs to the field of rebound device technology, and specifically relates to a rebound device. Background Technology

[0002] In mechanical devices and automated equipment, the bouncer is a common component that stores and releases energy to achieve a rapid response to mechanical movements. A traditional bouncer structure typically includes components such as a spring, housing, and base, which are combined through complex mechanical connections and fixing methods to achieve a specific function.

[0003] Existing technologies mainly include spring-driven rebound mechanisms and various forms of limiting and guiding mechanisms. The existing rebounders have relatively complex structures, containing multiple cooperating parts such as springs, housings, bases, limiting blocks, and guide blocks. The installation process is cumbersome, requiring precise alignment and fixation of each component to ensure proper operation. During use, friction and vibration between components can lead to wear and damage, affecting the equipment's lifespan and stability.

[0004] Existing rebound mechanisms have complex structures, leading to high production costs and difficulties in maintenance and component replacement. The installation process is cumbersome, requiring specialized technology and equipment, increasing installation costs and time. Furthermore, due to friction and vibration, existing rebound mechanisms are prone to component wear and damage, reducing equipment reliability.

[0005] In view of this, we have developed a simplified design that reduces unnecessary parts, making the structure more compact and easier to install and maintain. Through the precise matching of guide blocks and guide grooves with the slide rail, as well as the design of the guide grooves, we ensure the smooth sliding of the inner core, reduce vibration and friction, and improve the stability and accuracy of operation. The design of the limiting structure reduces the risks that may occur during operation, and the rapid rebound of the spring provides an efficient and safe energy conversion mechanism. Utility Model Content

[0006] The present invention aims to solve the technical problems of the above-mentioned prior art, such as the complex structure of the rebound device, which leads to high production costs, difficulties in maintenance and replacement of parts, and cumbersome installation process.

[0007] To achieve the above objectives, this utility model provides the following technical solution:

[0008] A rebounder includes a housing and a base, and an inner core, a positioning pin, a magnet, a spring, and a hook wire are installed in the mounting cavity formed by the housing and the base.

[0009] The inner core and the base are slidably guided together, and the front end of the inner core passes through the outer shell and the base. One end of the positioning pin is inserted into the positioning groove on the base, and the other end is guided into the hole groove of the inner core. The spring is sleeved on the outer side of the positioning pin and located at the inner end of the inner core. The magnet is located in the hole groove of the inner core. The hanging ring at one end of the hook is limited and sleeved on the support of the base, and the other end of the hook is hooked to the hook groove on the inner core.

[0010] By pressing the inner core once and squeezing the spring, the hook groove on the inner core engages with the hook line; by pressing the inner core a second time, the hook line disengages from the hook groove on the inner core, and under the spring's rebound, the inner core is partially ejected from the outer shell and base.

[0011] Preferably, the front end of the inner core has a threaded connection with teeth. This improves the strength of the connection and the ease of component replacement.

[0012] Preferably, the bottom of the base is provided with a sliding groove that cooperates with the inner core for guiding and sliding. The bottom of the base is also provided with a slide rail A that cooperates with guide groove A on the inner core for guiding and sliding, and a slide rail B that cooperates with guide groove B on the inner core for guiding and sliding. This ensures the accuracy and stability of the inner core's sliding.

[0013] Preferably, the outer casing is secured to the top outer side of the base, and mounting holes are provided on the flanges on both sides of the outer casing. This enhances the stability of the overall structure and the flexibility of installation.

[0014] Preferably, the base is equipped with a limiting block that positions the hook above it to prevent the hook from veering off course.

[0015] Preferably, the base is provided with guide grooves that cooperate with and limit the guide blocks A and B on the inner core. Guide groove A is located on guide block A, and guide groove B and hook groove are both located on guide block B. This precisely controls the sliding stroke of the inner core and improves the accuracy of motion control.

[0016] Compared with the prior art, the technical effects and advantages of this utility model are:

[0017] This rebounder achieves stable sliding and rapid rebound by precisely matching the guide block and guide groove between the inner core and the base with the slide rail, as well as the spring's elasticity storage and release mechanism. Specifically, when the inner core is pressed for the first time, the spring is compressed and stores elastic potential energy, while the hook groove on the inner core engages with the hook line; upon the second press, the hook line disengages from the inner core, the spring quickly rebounds, and pushes the inner core part out.

[0018] By optimizing the design, the structure of the bouncer was simplified, unnecessary parts were reduced, making installation and maintenance more convenient and reducing production costs. The cooperation between the guide block and guide groove and the slide rail, as well as the design of the guide groove, ensured the smooth sliding of the inner core, reduced vibration and friction, improved operational stability and accuracy, and also reduced potential risks during operation.

[0019] The rapid rebound of the spring provides an efficient energy conversion mechanism, while the limiting and guiding mechanisms reduce the possibility of component wear and damage, significantly extending the service life of the equipment and improving product reliability and durability. These characteristics make the spring rebounder perform exceptionally well in various application scenarios, meeting the requirements of rapid response and high reliability.

[0026] 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.

[0027] The following combination Figures 1 to 5 This application will be described in further detail.

[0028] This application discloses a rebound device, including a housing 1 and a base 2. The housing 1 is fixedly fastened to the top outer side of the base 2, and mounting holes 101 are provided on the flanges on both sides of the housing 1. The fixed fastening enhances the connection stability and prevents the housing 1 from falling off during operation. The mounting holes 101 facilitate installation and fixation, allowing the rebound device to be easily assembled with other components or equipment.

[0029] The inner core 3, positioning pin 4, magnet 5, spring 6, and hook 7 are installed in the mounting cavity formed by the outer shell 1 and the base 2. The front end of the inner core 3 is threaded with a tooth 8.

[0030] The inner core 3 is slidably guided to cooperate with the base 2. The bottom of the base 2 has a sliding groove 203 that guides the inner core 3. The guide block A305 on the inner core 3 has a guide groove A303, which cooperates with the slide rail A204 on the base 2 for sliding. The guide block B306 on the inner core 3 has a guide groove B304, which cooperates with the slide rail B205 on the base 2 for sliding. The base 2 also has a guide groove 207 that guides and limits the sliding stroke of the inner core 3. The guide groove 207 limits the guide blocks A305 and B306 on the inner core 3. The cooperation of the guide blocks and guide grooves with the slide rail ensures the smooth sliding of the inner core 3, reducing unnecessary vibration and friction. The guide groove 207 limits the sliding stroke of the inner core 3, protecting the internal structure, preventing excessive compression or stretching, and extending the service life of the equipment.

[0031] The inner core 3 is positioned through the outer shell 1 and the base 2. One end of the positioning pin 4 is inserted into the positioning groove 201 on the base 2, and the other end is guided into the hole groove 301 of the inner core 3. The spring 6 is sleeved on the outer side of the positioning pin 4 and located at the inner end of the inner core 3. The magnet 5 is located in the hole groove 301 of the inner core 3. The hanging ring 701 at one end of the hook 7 is limited and sleeved on the support column 202 of the base 2, and the other end of the hook 7 is engaged with the hook groove 302 on the inner core 3. The base 2 is provided with a limiting block 206 that limits the hook above the pin. The through-hole design of the inner core 3 increases the stability of the structure and improves the overall strength of the rebounder. The cooperation of the positioning pin 4 and the spring 6 ensures the correct position of the inner core 3, while the elasticity of the spring 6 provides a reliable energy storage and release mechanism. The base 2 also has a groove 208. The guide groove 207 and the groove 208 work together to form the switch of the rebound device. After the hook 7 and the hook groove 302 on the inner core 3 are hooked together, the guide block B306 is located above the groove 208. The design of the guide groove 207 and the groove 208 makes the opening and closing of the rebound device more stable.

[0032] Magnet 5 enhances the attraction between hook 7 and inner core 3. A single press of inner core 3, compressing spring 6, engages hook 7 with hook groove 302 on inner core 3. A second press disengages hook 7 from hook groove 302, and spring 6's rebound partially ejects inner core 3 from outer shell 1 and base 2. The hook 7's configuration allows for traction when releasing energy, while the retaining ring 701 ensures hook 7 remains in the correct position when inactive. A single operation sets the rebound state, making it easy for users. A second operation disengages hook 7 from inner core 3, and spring 6 quickly rebounds, achieving the rebound effect. This action can be rapid and powerful, suitable for applications requiring instantaneous energy release. Easy to operate and use, the precise limiting and guiding design improves device reliability. The limiting structure reduces potential operational risks, and the rapid rebound of spring 6 provides an efficient energy conversion mechanism.

[0033] The operating steps for this bouncer are as follows:

[0034] Initial press: When the user presses the inner core 3 for the first time, the spring 6 is compressed, storing elastic potential energy. At the same time, the hook groove 302 on the inner core 3 engages with the hook line 7, thus fixing the hook line 7 in place.

[0035] Positioning and limiting: The guide groove A303 on guide block A305 and the guide groove B304 on guide block B306 of inner core 3 cooperate with slide rails A204 and B205 on base 2 respectively to ensure that inner core 3 slides along the correct path. The guide groove 207 on base 2 limits the sliding stroke of inner core 3 to ensure that inner core 3 does not exceed the preset range.

[0036] Second press: The user presses the inner core 3 again, at which point the hook 7 disengages from the hook groove 302 on the inner core 3. Due to the rebound force of the spring 6, part of the inner core 3 is quickly ejected, achieving a rebound effect.

[0037] This bouncer has a simple structure and is easy to install. Through limiting and guiding mechanisms, the bouncer's movement is precisely controlled, thereby improving operational stability and accuracy. The limiting and guiding mechanisms also reduce potential accidents during operation, improving safety. The elasticity of spring 6 provides rapid rebound capability, which is very useful for applications requiring quick response. The structural fit and limiting mechanisms reduce the possibility of component wear and damage, increasing product lifespan and reliability. The design principle of this type of bouncer can be applied to various occasions, such as toys, mechanical devices, and automated equipment, and has wide applicability. This bouncer design achieves the storage and release of mechanical energy through physical principles, making it a highly efficient and practical mechanical structure.

[0038] 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.
