[0008] Module A, which consists of a slider and a hook. The bottom of the slider is provided with an axis position, and the top of the hook is fixed with a joint shaft, which is rotatably connected to the inner wall of the axis position;

[0009] The device further comprises a module B, which is composed of a main body and a pendulum needle. A pendulum needle shaft is fixedly mounted on the bottom of the main body, an axial hole is formed inside the pendulum needle, and the inner wall of the axial hole is slidably engaged with the outer wall of the pendulum needle shaft; a pendulum needle hole is formed at the bottom of the main body, and a column is fixedly mounted on the top of the pendulum needle, and the column is slidably engaged with the inner wall of the pendulum needle hole;

[0010] It also includes an energy storage component, which is used to realize the combination of module A and module B and store energy in the rebounder formed by the combination of the two;

[0011] It also includes a locking assembly, which is used to complete the locking and unlocking between module A and module B after the rebounder stores energy.

[0012] In one possible design, the energy storage assembly includes two spring cylinders arranged on one side of the main body, and springs are provided inside the two spring cylinders. Two spring columns are provided on one side of the slider, and the two spring columns are respectively slidably engaged with the inner walls of the two spring cylinders, and the two spring columns are engaged with the springs inside the corresponding spring cylinders; guide rails are provided on both sides of the protruding part of the main body, and a plurality of limit bars are provided at the bottom of the slider, and the plurality of limit bars are grouped in pairs, wherein the two limit bars located on the same side are slidably engaged with the same guide rail to complete the sliding combination of module A and module B.

[0013] In one possible design, a guide column is fixedly installed at the bottom of the hook, and a hook lock guide groove is provided at the top of the main body. The guide column is slidably connected to the inner wall of the hook lock guide groove to complete the sliding range limitation between module A and module B; two mounting openings are provided on both sides of the two guide rails, and multiple limit strips are matched with the mounting openings on the corresponding side to assist in completing the sliding limitation between module A and module B.

[0014] In one possible design, the locking assembly includes a swing lock guide groove opened at the bottom of the slider, the swing lock guide groove cooperates with the column, and a locking point is opened on the top inner wall of the swing lock guide groove, and the locking point is engaged with the column.

[0015] In a possible design, the hook further includes a locking block and a triggering block provided on one side thereof, and both the locking block and the triggering block cooperate with the slide rail strip of the external steel ball slide rail.

[0016] In one possible design, two fixing feet are provided at the bottom of the main body, and a screw mounting hole is opened inside the main body. The screw mounting hole and the two fixing feet cooperate with the external steel ball slide rail to complete the fixation of the rebounder.

[0017] In a possible design, a correction wall is provided inside the main body. The correction wall is located between two through holes at the ends of the hook lock guide groove and cooperates with the hook lock guide groove.

[0018] In this application, when in use, align the spring column of module A with the spring cylinder of module B and install it. Push module A along the guide rail until the limit bar can just be pressed into the installation opening. At this time, the guide column is aligned with the hook lock guide groove and pressed down, and then released. Module A will be pushed to the starting point by the spring, thus completing the assembly of the rebounder.

[0019] After the rebounder is installed as a whole into the steel ball slide rail, the fixing feet and screw mounting holes can complete the fixation of the rebounder; since the hook lock guide groove and the swing lock guide groove are respectively provided on the main body and the slider, when the product is assembled into a whole and installed in the steel ball slide rail, it will be divided into a hook lock area, a connection area, a swing lock area and an unlocking area according to the settings of the hook lock guide groove and the swing lock guide groove; when the trigger block of the hook buckle in the slider is subjected to the pressure of the slide rail strip, the trigger block moves in the direction of the swing needle, and the lock block will rotate around the axis under the action of the guide groove to complete the hook lock action, so as to implement the connection of the slide rail strip; when the slider moves to the end point, the pendulum needle column will be on the slide Under the action of the guide groove in the block, it is stuck in the locking point of the swing lock area. At this time, when the pressure is withdrawn, the slider and the slide rail strip can be fixed at the shortest distance position; when the slider is under pressure from the slide rail strip again, the slider moves again to make the column enter the unlocking area. At this time, the pressure is instantly stopped, and the spring in the spring cylinder will eject the slider together with the slide rail strip; because the hook in the slider will move in the opposite direction along the guide groove, when the slider moves to the end point, the lock block will unhook and release the slide rail strip, while module A will stop at the starting point due to the limit and guide column and will not be ejected together, thus completing one action cycle;

[0020] When module A in the rebounder is in the swing lock area and the slide rail strip is not locked by the hook, the user can press the slide rail strip against the locking block of module A. At this time, the guide column of the hook can generate pressure on the side wall of the hook lock guide groove, causing the correction wall to bend, thereby making enough space to open the locking block, allowing the slide rail strip to enter and complete the hook lock.

[0021] Beneficial effects:

[0022] In the present invention, the slide rail engineering plastic rebounder, by redesigning the hook structure and developing a new swing needle, can allow the rebounder to be used normally in a temperature range of -40°C to 60°C when engineering plastic is used as the main material, greatly expanding the application range of engineering plastic as the main material. This improvement not only improves the environmental adaptability of the product, but also reduces dependence on specific materials, helping to reduce costs.

[0032] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0033] Example 1

[0034] Reference Figure 1-4 A rebounder includes: module A, module B, an energy storage component and a locking component.

[0035] Module A is mainly composed of a slider 2 and a hook 4. The bottom of the slider 2 is designed with an axis 204, which is used to install and support the joint axis 401 of the hook 4 to ensure that the hook 4 can rotate freely around the axis 204.

[0036] Module B consists of a main body 1 and a pendulum 3. A pendulum shaft 105 is fixedly mounted on the bottom of the main body 1. Pendulum 3 slides with the shaft 105 through an internal shaft hole 302, enabling reciprocating motion of the pendulum 3 on the main body 1. Furthermore, a column 301 is provided on the top of the pendulum 3, which slides with the pendulum hole 104 at the bottom of the main body 1, further ensuring the stability of the pendulum 3's motion.

[0037] To achieve the combination and energy storage of modules A and B, this embodiment incorporates an energy storage assembly. Two spring cylinders 101 are mounted on one side of the main body 1, each containing a spring. Two spring columns 201 are mounted on one side of the slider 2. These columns slide against the inner walls of the two spring cylinders 101 and are acted upon by the elastic force of the springs. When module A slides relative to module B, the spring columns 201 compress the springs, converting mechanical energy into elastic potential energy for energy storage.

[0038] In addition, guide rails 109 are provided on both sides of the protruding portion of the main body 1, and multiple limit bars 205 provided at the bottom of the slider 2 are grouped in pairs and slideably cooperate with the guide rails 109 on the same side to ensure the stability and directionality of module A and module B during the sliding process.

[0039] To lock the positions of modules A and B after the rebounder accumulates energy, this embodiment also incorporates a locking assembly. Specifically, a swing lock guide groove 202 is provided at the bottom of the slider 2, which mates with the upright 301 of the pendulum needle 3. A locking point 203 is provided on the top inner wall of the swing lock guide groove 202. When the upright 301 moves to a specific position, it engages with the locking point 203, thereby locking modules A and B.

[0040] The present application can be used in the field of steel ball slide rail technology, and can also be used in other fields applicable to the present application.

[0041] Example 2

[0042] refer to Figure 3 、 4 , based on the improvement of Example 1: the slide rail engineering plastic rebounder is applied to the field of steel ball slide rail technology;

[0043] A guide post 402 is mounted at the bottom of the hook 4 and slidably engages the hook guide slot 102 at the top of the main body 1 to limit the sliding range between modules A and B. Furthermore, mounting openings 108 on either side of the guide rail 109 cooperate with the limit bars 205 to further restrict sliding movement, ensuring that the slider 2 does not separate from the main body 1 after being ejected.

[0044] A locking block 403 and a trigger block 404 are also provided on one side of the hook 4. These two components cooperate with the slide rail strip of the external steel ball slide rail to realize the locking and unlocking functions with the external slide rail strip, thereby facilitating the energy storage, locking and unlocking pop-up of the rebounder.

[0045] A correction wall 103 is also designed inside the main body 1, which is located between the two through holes at the end of the hook lock guide groove 102. It cooperates with the hook lock guide groove to facilitate the cooperation with the external slide rail strip so that the guide column 402 completes the extrusion and bending of the correction wall 103, which is conducive to better completing the hook lock of the external slide rail strip of the locking block 403.

[0046] The bottom of the main body 1 is provided with two fixing feet 106 and the interior is provided with screw mounting holes 107. These parts cooperate with the external steel ball slide rail to complete the fixed installation of the rebounder.

[0047] The working principle and usage process of this technical solution are as follows:

[0048] During use, align the spring column 201 of module A with the spring cylinder 101 of module B and install it. Push module A along the guide rail 109 until the limit bar 205 can just be pressed into the installation opening 108. At this time, the guide column 402 is aligned with the hook lock guide groove 102 and pressed down. Then release it, and module A will be pushed to the starting point by the spring, thus completing the assembly of the rebounder.

[0049] After the rebounder is installed in the ball bearing slide rail as a whole, the fixing foot 106 and the screw mounting hole 107 can complete the fixation of the rebounder; since the hook lock guide groove 102 and the swing lock guide groove 202 are respectively provided on the main body 1 and the slider 2, when the product is assembled into a whole and installed in the ball bearing slide rail, it will be divided into a hook lock area, a connection area, a swing lock area and an unlocking area according to the settings of the hook lock guide groove 102 and the swing lock guide groove 202; when the trigger block 404 of the hook buckle 4 in the slider 2 is subjected to the pressure of the slide rail strip, the trigger block 404 moves toward the swing needle 3, and the lock block 403 will rotate around the axis 204 under the action of the guide groove 102 to complete the hook lock action, and the slide rail strip can be connected; when the slider 2 moves to the end point, the column of the swing needle 3 Under the action of the guide groove 202 in the slider 2, 301 will be locked into the locking point 203 in the swing lock area. At this time, when the pressure is withdrawn, the slider 2 and the slide rail strip can be fixed at the shortest distance position; when the slider 2 is pressed by the slide rail strip again, the slider 2 moves again to make the column 301 enter the unlocking area. At this time, the pressure is instantly stopped, and the spring in the spring cylinder 101 will eject the slider 2 together with the slide rail strip; because the hook 4 in the slider 2 will move in the opposite direction along the guide groove 102, when the slider 2 moves to the end point, the lock block 403 is unhooked, and the slide rail strip can be released. Module A will be stopped at the starting point due to the limit 205 and the guide column 402 and will not be ejected together, thus completing one action cycle;

[0050] When module A in the rebounder is in the swing locking area and the slide rail strip is not locked by the hook 4, the user can press the slide rail strip against the locking block 403 of module A. At this time, the guide column 402 of the hook 4 can generate pressure on the side wall of the hook lock guide groove 102, causing the correction wall 103 to bend, thereby making enough space to open the locking block 403, allowing the slide rail strip to enter and complete the hook lock.

[0051] The above is only a preferred specific implementation method of the present invention, but the protection scope of the present invention is not limited to this. Any technician familiar with the technical field within the technical scope disclosed by the present invention can make equivalent replacements or changes based on the technical solution and utility model concept of the present invention, which should be covered by the protection scope of the present invention.
