[0030] In order to further understand the content of the present invention, the present invention is described in detail in conjunction with the accompanying drawings.

[0031] Figure 1 and Figure 2An explosion diagram of a slide rail press rebounder with a strong pull protection mechanism is shown. The strong pull protection mechanism of the press rebounder is a structural improvement on the existing slide rail press rebounder, which is installed on the slide slot seat 1 of the press rebounder. The slide slot seat 1 is provided with a swing hook slide slot 1-1 that cooperates with the swing hook 4. The main structure of the swing hook slide slot 1-1 can be found in the patent application filed by the applicant on July 1, 2019 with the patent number ZL201921007753.X and the name “A safe press rebound drawer slide”. The swing hook slide slot 1-1 includes a push slide slot, a rebound slide slot, and a closed slot located at the connection between the push slide slot and the rebound slide slot according to the functions of each slide slot. The front part of the closed slot has a deflection bevel to guide the swing hook 4 into the rebound slide slot, and one end of the push slide slot and the rebound slide slot also has a slide slot extension slot. Combined with Figure 4 As shown in (a), when the press-rebound device moves from the open state to the locked state, the swivel hook 4 moves upward along the propulsion chute and enters the chute extension groove. After releasing the propulsion force, the swivel hook 4 rebounds backward. Under the action of the closed slot, the swivel hook 4 hooks the closed slot and reaches the locked state; when the press-rebound device moves from the locked state to the open state, the inward pressing action causes the swivel hook 4 to move upward. Under the action of the deflection bevel, the swivel hook 4 swings in the direction of the rebound chute and enters the chute extension groove of the rebound chute. After releasing the pressing force, the swivel hook 4 moves in the rebound chute to complete the unlocking and rebounding. It is not difficult to see that in the locked state, the swivel hook 4 is stuck in the closed slot. If a strong pulling action is made at this time, it is bound to cause damage to the swivel hook 4 and the swivel hook chute 1-1, which will cause the press-rebound device to fail in severe cases.

[0032] The present invention provides a push-rebound strong-pull protection mechanism and a slide rail push-rebound using the same, the push-rebound strong-pull protection mechanism comprising a stopper 2 and an elastic member 3, an installation groove 1-2 is provided at the closed groove position of the swing hook slide groove 1-1 of the slide groove seat 1, the stopper 2 is installed in the installation groove 1-2, and the upper surface of the stopper 2 and the swing hook slide groove 1-1 form the closed groove position of the swing hook slide groove 1-1, the slide groove seat 1 is provided with a transition slide groove 1-3 located below the closed groove position and guiding to the rebound slide groove of the swing hook slide groove 1-1, the elastic member 3 is arranged between the slide groove seat 1 and the stopper 2, and is used to keep the stopper 2 at the closed groove position under normal circumstances, and to move the stopper 2 away when a strong pulling operation occurs to connect the closed groove position with the transition slide groove 1-3. It should be understood that the elastic force of the elastic member 3 is greater than the pulling force of the pressing rebounder on the swivel hook 4, so the stopper 2 will not move in a normal state. Only when the pressing rebounder is pulled forcefully by mistake, when the pulling force overcomes the elastic force of the elastic member 3, the stopper 2 will move. Figure 4As shown in (b), the stopper 2 is pressed down and moved away, connecting the closed slot with the transition slot 1-3. At this time, the swing hook 4 slides through the transition slot 1-3 into the rebound slot, thereby unlocking the press rebounder and effectively protecting the press rebounder from damage. By optimizing the elastic force of the elastic member 3, the press rebounder can also have the function of directly pulling the unlocking rebound.

[0033] exist Figure 1 and Figure 2 In the embodiment, there is a sliding fit relationship between the chute seat 1 and the swing hook mounting seat 5 for mounting the swing hook 4. Of course, the chute seat 1 can be used as a movable part or a fixed part. Accordingly, when the chute seat 1 is used as a movable part, the swing hook mounting seat 5 is a fixed part, and when the chute seat 1 is used as a fixed part, the swing hook mounting seat 5 is a movable part.

[0034] The present invention will be further described below in conjunction with the embodiments.

[0035] [Example]

[0036] like Figures 1 to 4 As shown, a strong pull protection mechanism for a press rebounder of the present embodiment is installed on a slide slot seat 1 of the press rebounder, and includes a stopper 2 and an elastic member 3. A mounting groove 1-2 is provided at the closed groove position of the swing hook slide slot 1-1 of the slide slot seat 1. The mounting groove 1-2 is connected front and back on the slide slot seat 1, and the mounting groove 1-2 is communicated with the closed groove position of the swing hook slide slot 1-1. The stopper 2 is installed in the mounting groove 1-2, and the upper surface of the stopper 2 is connected to the swing hook slide slot 1 -1 forms a closed slot of the swing hook slide 1-1, and the slide seat 1 is provided with a transition slide 1-3 located below the closed slot and guiding to the rebound slide of the swing hook slide 1-1. The elastic member 3 is arranged between the slide seat 1 and the stop member 2, so that the stop member 2 is located at the upper part of the installation slot 1-2, which is used to keep the stop member 2 at the closed slot under normal circumstances, and to move the stop member 2 away when a strong pulling operation occurs to connect the closed slot with the transition slide 1-3.

[0037] In this embodiment, the stopper 2 is installed in the installation groove 1-2 so as to slide up and down, and the elastic member 3 is installed below the stopper 2. The installation groove 1-2 of the slide seat 1 limits the stopper 2, so that the stopper 2 is kept in the closed groove position under the action of the elastic member 3, thereby forming a complete swing hook slide 1-1. The above-mentioned elastic member 3 is preferably a compression spring, and the elastic force of the elastic member 3 is greater than the pulling force exerted by the pressing rebounder on the swing hook 4. Furthermore, the rear part of the stopper 2 extends out of the back of the slide seat 1, and the rear part of the stopper 2 is installed on the slide seat 1 so as to slide up and down through the guide rod 2-1, and the structure is more stable and reliable. The stopper 2 can be slidably set on the guide rod 2-1, and the guide rod 2-1 is fixed to the back of the slide seat 1. As shown Figure 3As shown, in order to facilitate the assembly of the stopper 2, in this embodiment, a section of guide rod 2-1 is fixedly provided at the upper and lower ends of the rear part of the stopper 2, respectively. The stopper 2 and the guide rod 2-1 can be made in one piece, and the back of the slide seat 1 is provided with a guide groove 1-4 that is respectively slidably matched with the above-mentioned guide rod 2-1. The elastic member 3 is sleeved on the guide rod 2-1 at the lower part of the stopper 2, and is guided by the upper and lower sections of the guide rod 2-1, so the guidance is stable. The rear part of the guide groove 1-4 is provided with an opening for the guide rod 2-1 to be inserted, that is, the cross-sectional shape of the guide groove 1-4 is similar to a "C" shape, and the guide rod 2-1 can be inserted into the guide groove 1-4 by pressing, which is convenient for the installation of the stopper 2 and more convenient for assembly and manufacturing.

[0038] In this embodiment, the upper surface of the stopper 2 is an inclined plane, and the inclination direction of the upper surface of the stopper 2 is consistent with the inclination direction of the transition chute 1-3. The upper surface of the stopper 2 forms a "V"-shaped groove with the side wall of the closed slot of the swing hook chute 1-1, which can make the swing hook 4 stay stably in the closed slot, and at the same time, it is convenient to apply downward pressure to the stopper 2 when subjected to a strong pulling force, so that the stopper 2 overcomes the elastic force of the elastic member 3 and moves downward to guide through the transition chute 1-3, so that the swing hook 4 can pass through the transition chute 1-3 and enter the rebound chute, effectively protecting the press rebounder from damage.

[0039] like Figure 1 and Figure 2 As shown, the present embodiment also discloses a slide rail pressing rebounder, comprising a slide groove seat 1, a swivel hook 4, a swivel hook mounting seat 5, and a rebound spring arranged between the slide groove seat 1 and the swivel hook mounting seat 5, the swivel hook 4 is rotatably mounted on the swivel hook mounting seat 5, the slide groove seat 1 and the swivel hook mounting seat 5 are relatively slidably matched, and a swivel hook slide groove 1-1 matched with the above-mentioned swivel hook 4 is provided on the slide groove seat 1, and the slide groove seat 1 has the above-mentioned pressing rebounder strong pulling protection mechanism. One of the slide groove seat 1 and the swivel hook mounting seat 5 is a movable part, and the other is a fixed part; in the present embodiment, it is preferred to design the swivel hook mounting seat 5 as a movable part, and design the slide groove seat 1 as a fixed part. In order to facilitate the assembly of the pressing rebounder, a slide rail pressing rebounder of the present embodiment also includes a base 6, a chute seat 1 is fixedly installed in the base 6, specifically, a buckle can be set on the side wall of the chute seat 1, a slot is set at the corresponding position of the base 6, the chute seat 1 is fixed in the base 6 by snapping, and the swing hook mounting seat 5 is slidably installed in the base 6, specifically, a sliding guide structure can be set between the swing hook mounting seat 5 and the base 6, and a rebound spring is arranged between the base 6 and the swing hook mounting seat 5 to provide the elastic force of pressing rebound. The other structures of the slide rail pressing rebounder are the same as the existing design, which will not be repeated here.

[0040] See also Figure 4As shown, in a slide rail pressing rebounder of the present embodiment, under normal circumstances, the stopper 2 can be kept in the closed slot under the action of the elastic member 3. At this time, since the elastic force applied by the rebound spring on the swing hook 4 is less than the elastic force of the elastic member 3, the stopper 2 stays stably in the closed slot, so that the swing hook 4 can stay stably in the closed slot to achieve locking. When the pressing action is performed, the swing hook 4 can enter the rebound slide groove to achieve the normal pressing and rebounding operation of the press rebounder (such as Figure 4 (a) shown); in the event of misoperation and strong pulling, the force acting on the swing hook 4 increases, when the pulling force of the swing hook 4 is greater than the elastic force of the elastic member 3, such as Figure 4 As shown in (b), the swivel hook 4 forces the stopper 2 to move downward. When the stopper 2 passes over the transition slot 1-3, the stopper 2 slides into the rebound slot along the transition slot 1-3 to achieve rebound opening, which effectively protects the press rebounder from damage, avoids the press rebounder from being damaged and fails, and improves the use stability and service life of the press rebounder.

[0041] The invention relates to a push-rebound device strong-pull protection mechanism and a slide rail push-rebound device using the same, by arranging a stopper and a transition slot at the closed slot position of the original swing hook slot. Under normal circumstances, the stopper can be kept at the closed slot position under the action of the elastic member, so as to realize the normal push-rebound operation of the push-rebound device. When a strong-pull operation occurs, the stopper can be forcibly pulled away by the swing hook to connect the closed slot position with the transition slot, so that the swing hook is introduced into the rebound slot of the swing hook slot through the transition slot to realize rebound opening, effectively avoiding the push-rebound device from being damaged and failing, and improving the use stability and service life of the push-rebound device. In addition, the strong-pull protection mechanism of the push-rebound device is cleverly designed, simple and compact in structure, good in use stability, and easy to promote and apply in the push-rebound device of the drawer slide rail.
