Description

Technical Field

[0001] The utility model relates to the technical field of guide rails, in particular to a dual-functional synchronous unlocking mechanism for guide rails. Background Technique

[0002] The pressing synchronous rebounding device is commonly used as a functional accessory for concealed guide rails. It stores energy when closed and leaves a space for pressing and unlocking. By pressing the drawer, the drawer and other pull-out furniture are unlocked and rebounded, realizing the automatic opening of the pull-out furniture, which is very convenient to use and improves the use safety.

[0003] However, during the use of the traditional pressing synchronous rebounding device, when storing energy during closing and releasing energy during pressing, the drawer will directly impact the cabinet body, generating relatively large noise, even damaging each component, reducing the use stability and affecting the service life of the product.

[0004] Although the existing pressing synchronous rebounding device is provided with a buffer damper on the guide rail and has a damping effect when pushed back, when the drawer is loaded, especially when the load is large, after pressing and elastically deforming, when quickly pushed back into the cabinet, the damping force value cannot play a role and will be immediately triggered to rebound, and the drawer will be immediately ejected, resulting in the drawer being unable to be normally closed, posing a safety hazard. At the same time, when storing energy during closing, if the synchronous component of the pressing rebounding mechanism does not slide to the specified limit position without other external forces, the pressing rebounding mechanism will fail, seriously affecting the normal use of the drawer. Content of the Utility Model

[0005] The purpose of the utility model is to overcome the deficiencies of the prior art and provide a dual-functional synchronous unlocking mechanism for guide rails, which has a simple structure, can have a damping deceleration effect when pressing and popping out under a large load, and can avoid the failure of the pressing rebounding mechanism caused by the synchronous component not retracting to the specified position during natural closing, improving the structural stability and ensuring the normal use of the product.

[0006] The invention object of the utility model is achieved as follows: a dual-function synchronous unlocking mechanism for a guide rail, comprising a buffer rebound component arranged on the guide rail, the buffer rebound component comprising a base installed on the fixed rail of the guide rail, an energy storage sliding module with an energy storage function, and a toggle block that is buckled or separated from the movable rail of the guide rail as it is opened and closed, wherein the energy storage sliding module has a dial pin, the base is provided with a buffer silencer component for the dial pin to move in a locking direction with a reduced speed, a synchronous unlocking component for the dial pin to synchronously unlock, and a limiting component that can prevent the energy storage sliding module from contacting the synchronous unlocking component in a naturally locked state, the buffer silencer component is rotatably connected to the end head of the base and guides the dial pin to slide to the locked position, the limiting component comprises a limiting position and a limiting spring, the limiting position is located on one side of the buffer silencer component, and the two elastic ends of the limiting spring are respectively buckled on the base and the synchronous unlocking component and elastically act on the synchronous unlocking component, so that the synchronous unlocking component is connected to the limiting position in the naturally locked state.

[0007] According to the above optimization, the limit position is integrally formed behind the synchronous unlocking component, and the synchronous unlocking component has a limit gap with the energy storage sliding module at any position of the base under the elastic action of the limit spring.

[0008] According to the above optimization, the synchronous unlocking component includes a synchronous movable block, which is slidably connected to the base forward and backward, and one end of the synchronous movable block is matched and buckled with an elastic end of a limit spring. The synchronous movable block is connected to the limit position under the elastic action of the limit spring and forms a locking position with the front end of the base for putting the energy storage sliding module in a locked state. When the drawer is closed, the dial pin slowly slides to the locking position under the guidance of the buffer and silencer component.

[0009] According to the above optimization, the inner side of the synchronous movable block is provided with an unlocking position that engages with the setting pin when pressed to unlock, and the outer side of the synchronous movable block is provided with a connecting rod for linked forward and backward swinging, and the connecting rod is connected to a synchronous rod.

[0010] According to the above optimization, the buffering and silencing component includes a buffering and silencing wheel, and the dial pin slides back along the base under the elastic action of the energy storage sliding module while pushing the buffering and silencing wheel to rotate, so that the buffering and silencing wheel are dynamically frictionally connected with the base.

[0011] According to the above optimization, a limiting protrusion is provided at the rear end of the base, and the limiting protrusion and the base form a guide groove for the dial pin to move with the energy storage sliding module to achieve directional backward sliding, directional falling back to lock, and pressing rebound to slide forward, and a locking position is formed on one side of the limiting protrusion and the inner side of the synchronous unlocking component.

[0012] According to the above optimization, the energy storage sliding module includes an energy storage slider and a tension spring, the two elastic ends of the tension spring are respectively clamped on the front end of the energy storage slider and the base, the energy storage slider slides backward and is connected to the base under the push of the toggle block, the energy storage slider slides forward and is connected to the base under the action of the elastic potential energy of the tension spring, the dial pin is rotatably connected to the rear end of the energy storage slider, and there is a limiting gap between the energy storage slider and the synchronous unlocking component at any position.

[0013] The advantages of the utility model are:

[0014] 1) Through the cooperation of the buffer and silencer components and the base structure, after the energy storage sliding module is pushed back to store energy as the drawer is pushed, when the hand is released, the pin falls back under the action of the elastic potential energy of the energy storage sliding module and slowly falls to the locked position under the guidance of the buffer and silencer and the deceleration damping action, so as to achieve a damping and deceleration effect when pressing to pop out, which is particularly suitable for drawers with large load-bearing conditions and effectively achieves a silencing effect.

[0015] 2) Through the structural coordination of the limiting component and the synchronous unlocking component, the limiting spring can pull the synchronous unlocking component to the limiting position when not subject to external force, so that the energy storage sliding module and the synchronous unlocking component will not contact at any position during natural closing, effectively ensuring that the synchronous unlocking component will not fail due to being out of place during natural closing, and can achieve the synchronous unlocking component quickly returning to its position under the pulling force of the limiting spring after synchronous unlocking to wait for the next locking and unlocking operation, thereby ensuring the normal use of the product.

[0020] The utility model is further described below in conjunction with the accompanying drawings.

[0021] According to the attached Figures 1 to 4As shown, the dual-function synchronous unlocking mechanism for the guide rail of the utility model includes a buffer rebound component arranged on the guide rail, and the buffer rebound component includes a base 1 installed on the fixed rail of the guide rail, an energy storage sliding module 2 with energy storage function, and a toggle block that is buckled or separated from the movable rail of the guide rail as it is opened and closed. Among them, the energy storage sliding module 2 has a dial pin 23. The base 1 is provided with a buffer silencer component 3 for the dial pin 23 to move in the locking direction at a reduced speed, a synchronous unlocking component 4 for the dial pin 23 to be synchronously unlocked, and a limit component 5 that can prevent the energy storage sliding module 2 and the synchronous unlocking component 4 from contacting each other in the natural locking state. The buffer silencer component 3 is rotatably connected to the end of the base 1 and guides the dial pin 23 to slide to the locked position, and the limit component 5 includes a limit position 51 and a limit spring 52. The limit position 51 is located on one side of the buffer and silencer component 3, and the two elastic ends of the limit spring 52 are respectively buckled on the base 1 and the synchronous unlocking component 4 and elastically act on the synchronous unlocking component 4 so that the synchronous unlocking component 4 is connected to the limit position 51 when in the natural locked state.

[0022] Reference Figures 1 to 4 As shown, in further detail, the energy storage sliding module 2 includes an energy storage slider 21 and a tension spring 22. The two elastic ends of the tension spring 22 are respectively clamped on the front end of the energy storage slider 21 and the base 1. The energy storage slider 21 slides backward and is connected to the base 1 under the push of the toggle block 8, and the energy storage slider 21 slides forward and is connected to the base 1 under the elastic potential energy of the tension spring 22. The dial pin 23 is rotatably connected to the rear end of the energy storage slider 21, and there is a limit gap 53 between the energy storage slider 21 and the synchronous unlocking component 4 at any position.

[0023] The rear end of the base 1 is provided with a limiting protrusion 11. The limiting protrusion 11 and the base 1 form a guide groove 12 for the setting pin 23 to slide backward in a directional manner, fall back in a directional manner to lock, and slide forward in a directional manner by pressing and rebounding as the energy storage module moves. A locking position 6 is formed on one side of the limiting protrusion 11 and the inner side of the synchronous unlocking component 4.

[0024] When the drawer is closed, the toggle block 8 pushes the energy storage slider 21 to move backward along the base 1, and drives the dial pin 23 to move backward along the guide groove 12. When the drawer is closed to the specified position, the toggle block 8 separates from the energy storage slider, and the dial pin 23 moves to the left end slot of the guide groove 12. Under the elastic force of the tension spring 22, the energy storage slider 21 pulls the dial pin 23 along the guide groove 12 to fall back in the direction of the locking position 6.

[0025] Reference Figures 1 to 4As shown, for further refinement, the buffer and sound - damping component 3 includes a buffer and sound - damping wheel 31. While the dial pin 23 slides back along the base 1 under the elastic action of the energy - storage sliding module 2, it pushes the buffer and sound - damping wheel 31 to rotate, making the buffer and sound - damping wheel 31 in dynamic frictional connection with the base 1.

[0026] When the dial pin 23 quickly falls back, the dial pin 23 touches and pushes the buffer and sound - damping wheel 31. At this time, the buffer and sound - damping wheel 31 rotates and has dynamic friction with the base 1, thus effectively decelerating the dial pin 23 to achieve the buffer and sound - damping effect. At the same time, under the guidance of the buffer and sound - damping wheel 31, the dial pin 23 moves to the locking position 6.

[0027] Refer to Figures 1 to 4 As shown, for further refinement, the limiting position 51 is integrally formed at the rear of the synchronous unlocking component 4, and there is a limiting gap 53 between the synchronous unlocking component 4 and the energy - storage sliding module 2 at any position on the base 1 under the elastic action of the limiting spring 52.

[0028] Among them, the synchronous unlocking component 4 includes a synchronous moving block 41. The synchronous moving block 41 is slidably connected to the base 1 in the front - and - back direction. One end of the synchronous moving block 41 is fitted and buckled with an elastic end of the limiting spring 52. The synchronous moving block 41 is connected to the limiting position 51 under the elastic action of the limiting spring 52 and forms a locking position 6 for locking the energy - storage sliding module 2 with the front end of the base 1. When the drawer is closed, the dial pin 23 slowly slides to the locking position 6 under the guidance of the buffer and sound - damping component 3.

[0029] In this way, through the structural cooperation of the limiting component 5 and the synchronous unlocking component 4, when the synchronous unlocking component 4 is not under external force, the limiting spring 52 can pull the synchronous moving block 41 to the limiting position 51, ensuring that the energy - storage sliding module 2 and the synchronous moving block 41 will not contact at any position during natural closing, effectively guaranteeing that it will not fail due to the non - arrival of the synchronous moving block 41 during natural closing. The synchronous moving block 41 can quickly return to its original position under the pulling force of the limiting spring 52 after synchronous unlocking to wait for the next locking and unlocking operations, ensuring the normal use of the product.

[0030] In addition, an unlocking position 7 for engaging with the dial pin 23 when pressing for unlocking is provided inside the synchronous moving block 41, and a connecting rod 42 for linkage of front - and - back swinging is provided outside the synchronous moving block 41. The connecting rod 42 is connected to a synchronous rod.

[0031] When the drawer is opened, simply press the drawer to push the dialing pin 23 to move backward along the right end of the guiding groove 12 and move away from the locking position 6. After releasing the hand, under the action of the elastic potential energy of the tension spring 22, the dialing pin 23 moves forward along the guiding groove 12, and then the dialing pin 23 snaps into the unlocking position 7, and overcomes the elastic force of the spring to push the synchronous moving block 41 to move forward. Under the linkage of the connecting rod 42 and the synchronous rod, the buffer rebound components on both sides are synchronously unlocked. The structure has high running stability and good synchronous unlocking effect. After unlocking, the dialing pin 23 is separated from the unlocking position 7 and continues to move forward along the guiding groove 12 to fully open the drawer.

[0032] The above specific embodiments are only the specific embodiments with better effects of the present invention. Any structure identical or equivalent to the dual-functional synchronous unlocking mechanism for the guide rail of the present invention is within the protection scope of the present invention.
