[0023] The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. In order to make the above-mentioned objects, features and advantages of the present application more obvious and easy to understand, many specific details are set forth in the following description to facilitate a full understanding of the present application. However, the present application can be implemented in many other ways different from those described herein, and those skilled in the art can make similar improvements without violating the connotation of the present application. Therefore, the present application is not limited to the specific embodiments disclosed below.

[0024] See also Figure 1-Figure 7 A push-type rebound device includes a push rod assembly 1 that is elastically telescopically movable on the rebound device, a lock member 2 that cooperates with a lock seat 3 is provided on the push rod assembly 1, and the lock member 2 is elastically movable on the push rod assembly 1; When the rebound device is in a pending state, the lock element 2 is located in the rebound device and engages with the lock seat 3 to form a locked position, thereby achieving locking; During the opening process of the rebound device, the push rod assembly 1 drives the lock member 2 to extend out of the rebound device, and the lock member 2 elastically separates from the lock seat 3 to release the lock.

[0025] When the rebound mechanism is in the pending state, the lock element 2 and the lock seat 3 engage to form a latching position to lock the door, effectively preventing the door from being accidentally opened without being pressed, greatly enhancing the stability and safety of the door after it is closed. When the rebound mechanism is activated, the push rod assembly 1 drives the lock element 2 out of the rebound mechanism, and the lock element 2 elastically disengages from the lock seat 3 to release the lock. This process is smooth and natural, and does not affect the normal press-to-open operation, ensuring user convenience. At the same time, it also realizes the flexible switching between the closed door locking and press-to-open unlocking functions.

[0026] When the rebound mechanism is in its pending state, one end of the lock base 3 is positioned between the lock element 2 and the latch 5, achieving mutual locking. This unique structural design enhances the secureness and stability of the lock compared to a simple snap-on lock. In actual use, when the door is subjected to external impact or slight shaking, the restraining cooperation between the lock base 3, the lock element 2, and the latch 5 effectively resists external forces and prevents accidental unlocking. During the opening of the rebound mechanism, the lock element 2 moves linearly along the latch 5, either vertically or horizontally, and disengages from the lock base 3. This provides a clear trajectory and pattern for the unlocking process, ensuring accuracy and consistency in the unlocking action.

[0027] When the push rod assembly 1 is in a pending state, an opening slot is provided on its top for the lock member 2 to move up and down, so that the lock member 2 can move up and down linearly in cooperation with the spring.

[0028] Alternatively, when the push rod assembly 1 is in a pending state, an opening slot is provided on its left or right side for the lock member 2 to move horizontally left and right, so that the lock member 2 cooperates with the spring to move linearly left and right.

[0029] The locking member 2 moves linearly up and down or left and right on the push rod assembly 1 and has a different movement direction from the push rod assembly 1; A slot 5 is provided between the lock member 2 and the push rod assembly 1; When the rebound device is in a pending state, one end of the lock seat 3 is limited between the lock element 2 and the card slot 5, so that the lock element 2 and the lock seat 3 are locked with each other; During the opening process of the rebound device, the lock member 2 moves linearly along the locking slot 5 in the up-down or left-right direction and separates from the lock seat 3 .

[0030] The push rod assembly 1 moves linearly back and forth on the rebound device.

[0031] The lock base 3 is provided with an operating member 6, and a locking portion 7 is provided between the operating member 6 and the lock member 2. The locking portion 7 forms an anti-detachment structure to prevent the operating member 6 from being separated from the lock member 2 in the locked state. When the door body is hit, the operating member 6 will not easily separate from the lock member 2, ensuring the durability of the locking function of the rebound device. The door body can only be effectively opened in the pressed state. When the user pulls the door body, the locking portion 7 is in the locked state, thus preventing the door body from being opened without being pressed.

[0032] The locking portion 7 includes a first locking groove provided on the inner side of the lock element 2 and a second locking groove provided on the operating member 6. When the locking portion 7 is in the locked state, the first locking groove overlaps the second locking groove, which is equivalent to the two locking grooves being in a bite state. In the locked state, the locking portion 7 effectively prevents the operating member from escaping from the lock element 2 at will.

[0033] The lock seat 3 is provided with an adjustment groove 8, and the action member 6 is provided with a connecting portion 9 that is limited and matched with the adjustment groove 8. The connecting portion 9 moves up and down in the adjustment groove 8 to adjust the upper and lower positions of the action member 6 on the lock seat 3.

[0034] The connecting portion 9 is annular, and its outer diameter is larger than the width of the adjusting groove 8. The strip length of the adjusting groove 8 is larger than the outer diameter of the connection between the connecting portion 9 and the operating member 6, so that the operating member 6 can move up and down along the adjusting groove 8. The connecting portion 9 is limited on one side of the adjusting groove 8 to prevent the operating member 6 from disengaging from the adjusting groove 8. This is convenient for the installer to align the operating member 6 with the lock member 2 through fine adjustment during the installation and debugging process. The connecting portion 9 and the operating member 6 are integrally connected. The connecting portion 9 is made of soft material. When the operating member 6 is installed in the adjusting groove 8 of the lock seat 3, the connecting portion 9 is directly squeezed through the adjusting groove 8. The connecting portion 9 passes through the adjusting groove 8 and is elastically deformed and reset to be limited to one side of the adjusting groove 8. A limiting ring 6.1 is provided on the operating member 6, which is limited on the other side of the adjusting groove 8. The limiting ring 6.1 and the connecting portion 9 limit the operating member 6 to the front and rear positions on the adjusting groove 8.

[0035] Alternatively, a separate rigid connection is adopted between the connecting portion 9 and the active member 6, and a screw hole for inserting the active member 6 is provided on the connecting portion 9, and a threaded column for inserting the screw hole is provided at one end of the active member 6. When adjusting, since the connecting portion 9 is pressed against the inner side of the door body and does not move, when the installer rotates the active member 6, the active member 6 and the connecting portion 9 are slightly loosened. At this time, the active member 6 and the connecting portion 9 are not completely separated, so that the active member 6 and the connecting portion 9 can move up and down along the adjustment groove 8. When the active member 6 needs to be fixed after the adjustment is completed, the active member 6 is rotated again and is tightly connected to the connecting portion 9. The limiting ring 6.1 of the connecting portion 9 and the active member 6 are both in contact with the outer side of the adjustment groove 8.

[0036] The lock seat 3 is fixed on the corresponding installation accessory, and the lock seat 3 is provided with an upper and lower adjustment part 4. The lock seat 3 and the installation accessory are connected through the upper and lower adjustment part 4, and the upper and lower position of the lock seat 3 on the installation accessory is adjusted by the upper and lower adjustment part 4.

[0037] The upper and lower adjustment parts 4 are long strip adjustment holes matched with screws. The upper and lower adjustment parts 4 are sunken slots. The lock seat 3 is fixed on the door body. By setting the upper and lower adjustment parts 4, the upper and lower installation positions of the lock seat 3 on the door body can be adjusted.

[0038] The push rod assembly 1 includes a push rod 10, which is provided with a receiving groove 11 for installing a lock member 2. A first elastic member 12 is provided between the receiving groove 11 and the lock member 2. The lock member 2 is provided with an anti-slip portion 13 limited on the inner side of the receiving groove 11. The lock member 2 is elastically limited and movable on the receiving groove 11 by the first elastic member 12 and the anti-slip portion 13.

[0039] The first elastic member 12 is a spring, and the anti-slip portion 13 is a step. The lock member 2 is elastic. When the lock member 2 is installed in the receiving groove 11, the anti-slip portion 13 squeezes into the receiving groove 11. After the anti-slip portion 13 passes over the receiving groove 11, the anti-slip portion 13 elastically deforms and abuts against the inner side of the receiving groove 11, preventing the lock member 2 from popping out of the receiving groove 11 under the action of the spring. The first elastic member 12 can provide elastic support for the lock member 2, acting as a buffer during the locking process and as an elastic automatic unlocking function during the unlocking process. The anti-slip portion 13 prevents the lock member 2 from accidentally disengaging from the receiving groove 11 during movement, thereby improving the reliability of the entire rebound device.

[0040] A position-limiting fitting portion 16 is provided between the push rod 10 and the housing 14 to allow the push rod 10 to be position-limited and telescopically movable on the housing 14 .

[0041] The limiting fitting portion 16 prevents the push rod 10 from detaching from the shell 14 when it is elastically extended. The limiting fitting portion 16 includes a step groove arranged in the shell 14 and a positioning step arranged on the push rod 10. The inner cavity of the shell 14 is a hollow structure; the push rod 10 is inserted into the shell 14 from back to front, so that the positioning step can abut against the step groove in the shell 14. A fixing part 23 is provided at the rear end of the shell 14. The fixing part 23 and the shell 14 are provided with a connecting pin in the vertical (up and down) direction, and the swinging part 22 is rotatably set on the fixing part 23.

[0042] The push-type rebound device also includes a shell 14 for installing the push rod assembly 1, and the lock member 2 is provided with a slope 15. During the closing process of the rebound device, the lock member 2 retreats into the shell 14 along with the push rod assembly 1, and the slope 15 acts on the shell 14 to enable the lock member 2 to enter the accommodating groove 11 and move along the direction of locking the lock seat 3.

[0043] The push rod assembly 1 further includes a sliding member 17 fixedly connected to the push rod 10 , a second elastic member 18 is provided between the sliding member 17 and the housing 14 , and the push rod assembly 1 is elastically and telescopically arranged on the housing 14 via the second elastic member 18 .

[0044] The second elastic member 18 is a spring.

[0045] In this embodiment, the push rod 10 and the sliding member 17 are fixedly connected via a threaded structure.

[0046] The sliding member 17 is provided with an opening track groove 19, a closing track groove 20 and a closing stop position 21; A rotating swing member 22 is provided in the housing 14; During the closing process of the rebound device, the swing member 22 moves along the closing track groove 20 to the closing stop position 21; During the opening process of the rebound device, the swing member 22 moves along the closing stop position 21 to the opening track groove 19. The swing member 22 is provided with a hook limited on the track groove.

[0047] The specific movement structure of the rebound device can be referred to a rebounder disclosed in Chinese Patent No. 202211435770.X. The main improvement of this technical solution lies in the lock member 2 and the lock seat 3. The other structures are roughly the same as the rebounder disclosed in Chinese Patent No. 202211435770.X, so the specific connection structure will not be described in detail here.

[0048] The rebound device of this technical solution is fixed in the cabinet by a fixing seat, and the lock seat 3 is fixed on the inner side of the door body by screws. The rebound device of this technical solution can also be applied to a drawer.

[0049] A push-to-open sign may be provided on the door to prevent the user from forcibly pulling the door.

[0050] The specific working process of the rebound device is as follows: When the door is closed on the cabinet, the user presses the door, and the door squeezes the push rod assembly 1 and the second elastic member 18 toward the lock seat 3 and the lock member 2. The push rod assembly 1 is pushed out under the release of the elastic force of the second elastic member 18. At this time, the track groove of the sliding member 17 cooperates with the swing member 22, and the swing member 22 moves relatively along the closing stop position 21 to the opening track groove 19, so that the push rod assembly 1 gradually extends out of the rebound device, and the lock member 2 moves to the outside of the rebound device as the push rod assembly 1 extends. When the lock member 2 extends out of the outside of the rebound device and moves linearly upward to disengage from the lock seat 3, the user can open the door by hand. When the door body is closed, the operating member 6 of the lock seat 3 of the door body is first inserted into the card slot 5, and then the door body pushes the push rod assembly 1 back in the closing direction to the rebound device. When the inclined surface 15 of the lock member 2 retreats with the push rod assembly 1 to contact the shell 14, the inclined surface 15 of the lock member 2 moves linearly downward under the action of the outer side of the shell 14 to enter the card slot 5 (in the rebound device) to squeeze the first elastic member 12 and move in the direction of locking the operating member 6 of the lock seat 3 to re-lock the operating member 6 and close the door body. At this time, the second elastic member 18 is in a compressed state, and when the push rod assembly 1 retreats to the rebound device, the swing member 22 moves along the closed track groove 20 to the closed stop position 21, so that the push rod assembly 1 is positioned in the rebound device in a pending state.

[0051] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
