Description

Technical Field

[0001] The invention relates to a drawer slide rail pressing and rebounding device, and more particularly to a multifunctional slide rail pressing and rebounding device with a strong pulling protection function. Background Art

[0002] At present, the slides installed in furniture, cabinets, and drawers are mainly of two types: pull-out type and push-rebound type. The pull-out drawer slide is to pull the drawer by hand to make the drawer slide along the slide. The push-rebound drawer slide is to push the drawer inward for a certain distance and then trigger the rebound device to make the drawer automatically pop out. It is very convenient to use, and the push-rebound drawer slide can prevent children from opening the drawer, which has higher safety. Therefore, the push-rebound drawer slide is more and more widely used.

[0003] The key component of the push-rebound drawer slide is the rebounder (or rebound device), which is generally composed of a slider seat, a slider, an elastic part and a striker clamp. The slider is installed in the slider seat, and the elastic part is installed between the slider seat and the slider. A slide groove and a hook are usually provided between the slider seat and the slider for cooperation. The position of the slider in the slider seat is controlled by utilizing the different positions of the hook in the slide groove. For example, Chinese patent number ZL201711397400.0, application publication date May 4, 2018, invention name: A labor-saving push-rebound mechanism for furniture, the application case relates to a labor-saving push-rebound mechanism for furniture, including a push-rebound device, the push-rebound device at least includes a rebound bracket and a push element, the push element is positioned and / or slides on the rebound bracket, the rebound bracket is provided with a heart-shaped slide groove, the push element is provided with a sliding part and a sliding element, the sliding element is slidably arranged on the push element; the push element is positioned on the rebound bracket, and the sliding element acts on the sliding part when sliding on the push element, the sliding part slides along the track of the heart-shaped slide groove in a sequential direction, and drives the push element to slide on the rebound bracket. The push-rebound mechanism of the application case can make the drawer slide rail rebound and open after being pressed, which improves the convenience of use. However, since pull-out or push-rebound slide rails are now common, unfamiliar consumers or users do not know how to open the drawer, which can easily lead to the rebounder being damaged and failing due to improper operation by the user and forced opening of the drawer.

[0004] In addition, the existing drawer slide rail pressing and rebounding devices have high requirements for their installation positions on the slide rails and the slide rails in the drawers. It is necessary to ensure that the drawer has a pressing stroke of about 3 mm after closing. If the pressing stroke is insufficient, it is difficult to trigger the rebounder, which brings many inconveniences to the installation and adjustment of the drawer. In addition, the rebound force of the existing pressing and rebounding devices cannot be adjusted. For some larger or heavier drawers, the rebound stroke is often small due to insufficient rebound force, which also brings a lot of inconvenience to the use of the drawer. In order to improve the synchronization of the left and right slide rails on both sides of the drawer, many slide rails will design the left and right slide rails as synchronous slide rails, but setting a synchronization mechanism in the drawer has a complex structure, is difficult to manufacture, and has a high manufacturing cost.

[0005] Based on the above-mentioned deficiencies of the existing drawer slide rail push-rebound device, it is urgently necessary to design a push-rebound device that is easy to operate, install and adjust. Summary of the invention

[0048] In order to further understand the content of the present invention, the present invention is described in detail in conjunction with the accompanying drawings and embodiments.

[0049] [Example 1]

[0050] like Figures 1 to 6 As shown, a multifunctional slide rail press rebounder with a strong pull protection function of the present embodiment includes a fixed part 12 and a movable part 13 that can slide relative to each other, and the fixed part 12 and the movable part 13 are fixed or movable relative to each other. When the press rebounder is installed on the fixed rail 51 of the slide rail 5, the fixed part 12 is stationary relative to the fixed rail 51, and the movable part 13 can slide relative to the fixed part 12. When the press rebounder is installed on the movable rail 53 of the slide rail 5, the entire press rebounder moves with the movable rail 53, and the movable part 13 can slide relative to the fixed part 12 inside the press rebounder. A striker clamp 14 is rotatably mounted on the movable part 13, and the striker clamp 14 moves relative to the fixed part 12 together with the movable part 13, and a rebound elastic member 16 for providing a rebound force is provided on the movable part 13, and the rebound elastic member 16 is preferably a tension spring, and a plurality of tension springs can be arranged side by side according to the elastic force; a clamping head slide groove 12-6 is provided on the fixed part 12 for cooperating with the striker clamp 14 to control the swinging action of the striker clamp 14, such as Figure 4 and Figure 5As shown, a chuck shaft 13-1 is provided on the movable part 13, and a striker chuck 14 is rotatably installed on the chuck shaft 13-1. A striker slot 14-1 capable of cooperating with the striker and a limit column 14-2 capable of cooperating with the chuck slot 12-6 are provided on the striker chuck 14. The chuck slot 12-6 includes a straight section and a rotary section. When the limit column 14-2 is located in the straight section, the striker chuck 14 swings out to engage with the striker. When the limit column 14-2 is located in the rotary section, the striker chuck 14 swings inward to release the striker. One of the fixed part 12 and the movable part 13 is provided with a swivel hook slot 12-5, and the other is provided with a swivel hook 15 which can sequentially swing and rotate within the trajectory of the swivel hook slot 12-5 and stay in the corresponding slot. That is, the swivel hook slot 12-5 can be arranged on the fixed part 12, and the swivel hook 15 can be arranged on the movable part 13, or the swivel hook slot 12-5 can be arranged on the movable part 13, and the swivel hook 15 can be arranged on the fixed part 12. In this embodiment, the former is preferred, that is, the swivel hook slot 12-5 is arranged on the fixed part 12, and the swivel hook 15 is arranged on the movable part 13. At this time, the fixed part 12 is the slot seat, and the movable part 13 is the slider. The above-mentioned swing hook slot 12-5 includes a push slot, a rebound slot connected in sequence, and a closed slot located at the connection between the push slot and the rebound slot. One end of the swing hook 15 is rotatably mounted on the movable part 13, and the other end of the swing hook 15 has a hook head 15-1 that slides sequentially in the swing hook slot 12-5. The matching relationship between the swing hook slot 12-5 and the swing hook 15 can be found in the patent number ZL201921007753.X filed by the applicant on July 1, 2019, entitled "A safe press-rebound drawer slide" According to the application, when the drawer is closed, the hook head 15-1 of the swing hook 15 slides from the push chute into the closed slot for positioning, at which time the striker clamp 14 clamps the striker, and the hook head 15-1 of the swing hook 15 is positioned at the closed slot, thus locking the drawer; when the drawer is pressed inward, the hook head 15-1 of the swing hook 15 is blocked by the guide slope when moving forward and swings toward the rebound chute, disengaging from the closed slot. At this time, after releasing the hand, the swing hook 15 enters the rebound chute under the action of the rebound elastic member 16, and the movable member 13 pushes the drawer to slide outward, thus opening the drawer. When the drawer is forcibly pulled when the drawer is in the closed state, the hook head 15-1 of the swing hook 15 will be deformed or even broken by excessive tension, thereby damaging the swing hook 15 and the swing hook chute 12-5, and causing the press rebounder to fail. In this embodiment, a transition slot 12-5a guiding to the rebound slot is provided below the closed slot position of the swing hook slot 12-5, and a strong pulling protection mechanism is provided at the closed slot position of the swing hook slot 12-5 for connecting the closed slot position with the transition slot 12-5a when a strong pulling operation occurs.The strong-pull protection mechanism is a mechanism that can be pulled open. Under normal conditions, the elastic force of the strong-pull protection mechanism is greater than the pulling force of the hook head 15-1 of the swivel hook 15. Therefore, the hook head 15-1 of the swivel hook 15 can stably cooperate with the closed slot of the swivel hook slide 12-5. When subjected to a strong pulling force, the force of the swivel hook 15 acting on the strong-pull protection mechanism becomes greater, which will force the strong-pull protection mechanism to open, so that the closed slot is connected to the transition slide 12-5a. At this time, the swivel hook 15 will slide along the transition slide 12-5a into the rebound slide, thereby unlocking the push-rebound device and effectively protecting the push-rebound device from damage.

[0051] like Figure 2 , Figure 3 and Figure 6 As shown, in this embodiment, as a preferred implementation mode, the above-mentioned strong pull protection mechanism includes a strong pull stopper 12-2 and a strong pull elastic member 12-3, and a sliding block groove is opened at the closed groove position of the swing hook slide 12-5, and the strong pull stopper 12-2 is slidably installed in the sliding block groove, and the upper surface of the strong pull stopper 12-2 and the swing hook slide 12-5 together form the closed groove position of the swing hook slide 12-5, and the strong pull elastic member 12-3 is arranged below the strong pull stopper 12-2. The strong pull elastic member 12-3 is used to keep the strong pull stopper 12-2 in the closed groove position under normal circumstances, and when a strong pull operation occurs, the swing hook 15 drives the strong pull stopper 12-2 to overcome the elastic force of the strong pull elastic member 12-3 and move downward to connect the closed groove position with the transition slide 12-5a. The strong pull elastic member 12-3 preferably adopts a compression spring. It should be understood that the elastic force of the strong pull elastic member 12-3 is greater than the pulling force of the pressing rebounder on the swing hook 15. Therefore, under normal conditions, the strong pull stop member 12-2 will not move. Only when an erroneous operation occurs and the pressing rebounder is forcibly pulled, when the pulling force overcomes the elastic force of the strong pull elastic member 12-3, the strong pull stop member 12-2 is pressed down and moved away, connecting the closed slot with the transition slot 12-5a. At this time, the swing hook 15 slides into the rebound slot through the transition slot 12-5a. By optimizing the elastic force of the strong pull elastic member 12-3, the pressing rebounder can also have the function of directly pulling the unlocking rebound. For other specific structures and working principles of the strong pull protection mechanism, please refer to the patent application number 202010569491.7 submitted by the applicant on June 20, 2020, entitled "A press-rebound strong pull protection mechanism and a slide rail press-rebound using the same", which will not be repeated here.

[0052] The multifunctional slide rail pressing rebounder with strong pull protection function of this embodiment can also be divided into two action situations according to the installation method of the pressing rebounder:

[0053] When the pressing rebounder is installed on the fixed rail 51 of the slide rail 5, the striker is installed on the movable rail 53 of the slide rail 5. When the drawer is closed, the movable rail 53 drives the striker to move toward the pressing rebounder. When the striker hits the striker clamp 14, it drives the striker clamp 14 to move backward. During the movement of the striker clamp 14, the striker clamp 14 is deflected outward by the clamping slot 12-6 and opens and closes with the striker. At this time, the striker clamp 14 drives the movable part 13 to move backward relative to the fixed part 12, and the swivel hook 15 moves along the pushing slot of the swivel hook slot 12-5. After it is in place, the drawer is released. At this time, the swivel hook 15 is guided into the closing slot during the retreat process to achieve the closing of the drawer; press the drawer again, and the swivel hook 15 enters the rebound slot from the closing slot to complete the pressing rebound.

[0054] When the push-rebound device is installed on the movable rail 53 of the slide rail 5, the striker is installed on the fixed rail 51 of the slide rail 5. When the drawer is closed, the movable rail 53 drives the push-rebound device to move. When the striker clamp head 14 of the push-rebound device hits the striker, it stops moving. At this time, the fixed part 12 in the push-rebound device continues to move relative to the movable part 13. Similarly, when the fixed part 12 moves, the striker clamp head 14 is deflected outwards under the action of the clamp head slide groove 12-6, and the Figure 6 (a) to Figure 6 As shown in (b), the striker clamp 14 opens and closes with the striker, and at the same time, the swing hook 15 moves along the push slide of the swing hook slide 12-5, and the drawer is released after it is in place. At this time, the swing hook 15 is guided into the closed slot during the retreat process to achieve the closing of the drawer, as shown in FIG. Figure 6 (b) state shown; press the drawer again, the swing hook 15 enters the rebound chute from the closed slot, completes the press rebound, and returns to Figure 6 The state shown in (a).

[0055] In the above two cases, if the drawer is forcibly pulled, the swing hook 15 can make the strong pull stopper 12-2 overcome the elastic force of the strong pull elastic member 12-3 downward, so that the swing hook 15 can enter the rebound chute from the transition chute 12-5a. By setting a strong pull protection mechanism at the closed slot of the swing hook chute, when a strong pull operation occurs, the strong pull protection mechanism can be used to guide the swing hook through the transition chute into the rebound chute of the swing hook chute to realize rebound opening, effectively avoiding the problem of the press rebounder being damaged and failing, and improving the use stability and service life of the press rebounder; and the above-mentioned strong pull protection mechanism has a clever structural design, a simple and compact structure, good use stability, and is easy to manufacture, and is easy to promote and apply in the drawer slide rail press rebounder.

[0063] Of course, the present invention is not limited to the specific structure of the elastic gear position adjustment mechanism mentioned above, and a push-pull mechanism similar to a screw-nut push-pull mechanism or a gear rack push-pull mechanism can also be adopted, as long as the pre-stretching length of the rebound elastic member 16 can be changed.

The axial elastic piece 43 is provided between the gear connecting piece 42 and the synchronization rod connecting piece 44. The axial elastic piece 43 is preferably a spring. In order to facilitate the installation of the axial elastic piece 43, a core column is also provided in the polygonal hole of the gear connecting piece 42. The axial elastic piece 43 is sleeved on the core column. The axial elastic piece 43 is used to make the synchronization rod connecting piece 44 on the gear connecting piece 42 have a tendency to extend outward. The end of the synchronization rod connecting piece 44 is provided with a synchronization rod plug connector 44b that is plugged with the synchronization rod 45. The synchronization rod plug connector 44b has a polygonal cross-sectional structure, and the end of the synchronization rod 45 also has a matching polygonal structure. By utilizing the above-mentioned elastic plug-in component design, the installation of the synchronization rod 45 can be facilitated when the drawer slide is installed and adjusted. During operation, only one end of the synchronization rod 45 needs to be inserted into the elastic plug-in component of the press-rebound device on one side, and the synchronization rod is pushed hard to compress the elastic plug-in component, so that the other end of the synchronization rod can be smoothly inserted into the elastic plug-in component of the press-rebound device on the other side. The connection operation is simple and convenient, and the stability is good after connection.
