Description

Technical Field

[0001] This utility model relates to the field of door control hardware, and in particular to a two-way buffer cabinet door gas spring. Background Technology

[0002] In the field of modern furniture hardware, cabinet door gas springs are key components for smooth opening and closing of cabinet doors, and their performance directly affects the user experience. Currently, gas springs on the market suffer from the following technical defects: First, traditional gas spring structures mostly use a single spring or gas rod design, providing only basic support and failing to effectively buffer the impact force during cabinet door movement, resulting in significant noise and vibration when the door closes. Second, existing technologies mostly focus on opening buffering while neglecting closing buffering, causing the door to impact the cabinet body instantly when closing, affecting usability, posing safety hazards, and compromising cabinet structural stability. Third, existing buffering structures are relatively complex, increasing manufacturing costs and making installation and maintenance inconvenient. Finally, the buffering adjustment mechanisms of existing gas springs are not simple enough to quickly adapt to the buffering needs of cabinet doors of different weights. To address these issues, there is an urgent need to develop a cabinet door gas spring with bidirectional buffering function, stable and reliable structure, and long service life to meet the increasingly higher quality requirements of modern furniture hardware. Utility Model Content

[0003] This utility model aims to solve at least one of the technical problems existing in the prior art. To this end, this utility model proposes a two-way buffer cabinet door gas spring, which can realize two-way buffering during the opening and closing process. The overall structure is reasonably laid out, and all components work together to ensure the stability of the buffering effect and meet the high-quality requirements of modern furniture for hardware accessories.

[0004] The technical solution adopted by this utility model to solve its technical problem is:

[0005] A two-way buffer cabinet door gas spring, including

[0006] A first connecting seat is used to connect with a cabinet door. The top surface of the first connecting seat is provided with a mounting groove, and hinge seats are provided on both sides of the mounting groove.

[0007] A hydraulic assembly includes a hydraulic rod and a slide plate. The hydraulic rod is disposed in the mounting groove. The slide plate is L-shaped and includes a long side and a short side. The short side abuts against the end face of the hydraulic rod. The long side is located on the upper side of the mounting groove. A first abutting block protruding upward is provided at the end of the long side away from the short side.

[0008] The gas strut is hinged at one end to the two hinge seats, which serves as a door opening buffer. The gas strut and the second abutment block located at one end of the hinge seat are provided with a second abutment block. The second abutment block abuts against the first abutment block, thereby driving the slide to press the hydraulic rod to serve as a door closing buffer.

[0009] The second connecting seat is located at the other end of the gas strut and is used to connect to the inner side of the cabinet.

[0010] A bidirectional buffer cabinet door gas spring according to an embodiment of this utility model has at least the following beneficial effects: when the cabinet door is opened, the gas spring itself provides a buffering effect during the opening process; when the cabinet door is closed, the gas spring resets to achieve automatic closing, and simultaneously, the second abutment block of the gas spring pushes the first abutment block of the slide plate, causing the slide plate to press against the hydraulic rod. The hydraulic rod generates a buffering force, achieving a buffering effect in the closing process and preventing the cabinet door from instantly impacting the cabinet body when closing, thus affecting the usability. The entire process achieves bidirectional buffering through the synergistic action of the hydraulic components and the gas spring. This device achieves multiple beneficial effects through innovative structural design, including bidirectional buffering during opening and closing, reduced vibration and noise, elimination of the safety hazard of sudden cabinet door opening, extended service life, simplified installation and maintenance procedures, and flexible adjustment to adapt to different cabinet door weights and usage needs. The overall structural layout is reasonable, and the components work together to ensure the stability of the buffering effect while meeting the high-quality requirements of modern furniture hardware.

Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0040] The following is for reference. Figures 1-4 A bidirectional buffer cabinet door gas spring is described in detail with reference to a specific embodiment. It is to be understood that the following description is merely illustrative and not a specific limitation of the invention.

[0041] like Figures 1-4 As shown, the cabinet door gas spring device mainly consists of a first connecting seat 100, a hydraulic assembly, a gas spring rod 180, and a second connecting seat 200. The first connecting seat 100 is used to connect to the cabinet door. Its top surface has a mounting groove 110, and hinge seats 120 are located on both sides of the mounting groove 110. This design ensures stable installation and smooth movement of the gas spring rod 180. The first connecting seat 100 adopts a U-shaped structure, including a protruding part 210 and a bottom edge 220. The mounting groove 110 is located on the top surface of the protruding part 210, and the hinge seats 120 are located on both sides of the protruding part 210. This structure enhances the overall strength and facilitates the arrangement of various components. The bottom edge 220 has first bolt holes 230 on both sides of the protruding part 210, making installation more convenient and allowing for flexible adjustment of the installation position according to different cabinet door thicknesses. One end of the mounting slot 110 is provided with an open opening 240, and slots 250 are provided on both sides of the open opening 240. A baffle 26 is installed in the slot 250. This design facilitates installation and replacement, protects the internal components, and facilitates daily maintenance.

[0042] Specifically, such as Figure 3 and Figure 4 As shown, the hydraulic assembly is the core component of the device, including a hydraulic rod 130 and a sliding plate 140. The hydraulic rod 130 is disposed within the mounting groove 110, and the sliding plate 140 has an L-shaped structure, including a long side 150 and a short side 160. The short side 160 abuts against the end face of the hydraulic rod 130, and the long side 150 is located on the upper side of the mounting groove 110. A first abutment block 170 protrudes upwards at the end of the long side 150 away from the short side 160. This unique L-shaped design ensures effective transmission of buffering force while avoiding wear caused by direct contact. Similarly, the upper two sides of the mounting groove 110 should be provided with sliding grooves 350 that allow the long side 150 to move horizontally, and the width of the short side 160 is smaller than the width of the long side 150. This facilitates the movement of the sliding plate 140 while preventing it from detaching from the mounting groove 110. The sliding plate 140 is made of stainless steel or aluminum alloy, ensuring sufficient strength and elasticity while possessing excellent corrosion resistance. One end of the gas strut 180 is hinged to two hinge seats 120, and the other end has a second connecting seat 200. The gas strut 180 uses its own buffering function to buffer the opening of the door and reset to automatically close the door when closed. Additionally, the end of the gas strut 180 connected to the hinge seat 120 has a second abutment block 190, which abuts against the first abutment block 170. This allows the sliding plate 140 to press against the hydraulic rod 130, providing a door-closing buffer and preventing the cabinet door from impacting the cabinet body and affecting its usability. The gas strut 180 includes a rod body 270 and an output shaft 280. The end of the rod body 270 is hinged to the hinge seat 120, and the end of the output shaft 280 is connected to the second connecting seat 200. The end of the rod body 270 is provided with a connecting sleeve 290, the connecting sleeve 290 is provided with a first hinge hole 300, and the hinge seat 120 is provided with a second hinge hole 310 corresponding to the first hinge hole 300. The first hinge hole 300 and the second hinge hole 310 are rotatably connected by a hinge shaft. This design makes the gas strut 180 rotate more smoothly and reduces friction loss.

[0043] like Figure 1 and Figure 2As shown, the second connecting seat 200 is located at the other end of the gas strut 180 and is used to connect to the inner side of the cabinet. The second connecting seat 200 includes a rotating part 320 and a mounting part 330. The rotating part 320 is rotatably connected to the output shaft 280 on the same axis, and the mounting part 330 is rotatably connected to the side of the rotating part 320. This design ensures the free rotation of the gas strut 180 and improves the overall stability of operation. The mounting part 330 is provided with second bolt holes 340 on both sides of the rotating part 320, making the connection more secure and allowing for flexible adjustment of the installation method according to different cabinet structures. The first connecting seat 100 and the second connecting seat 200 are made of plastic, which reduces the overall weight and manufacturing cost, while also providing good wear resistance and impact resistance.

[0044] The working process of the cabinet door gas spring device is as follows: When the cabinet door is opened, the gas spring 180 uses its own buffering action to achieve a gradual buffering of the opening process, preventing the door from opening too quickly; when the cabinet door is closed, the gas spring 180 achieves an automatic closing effect, and at the same time, the second abutment block 190 of the gas spring 180 pushes the first abutment block 170 of the slide plate 140, such as... Figure 3 As shown, the sliding plate 140 presses against the hydraulic rod 130, which generates a buffering force, thus buffering the door when it closes and preventing the cabinet door from impacting the cabinet body and affecting its usability. The entire process achieves a two-way buffering function through the coordinated action of the hydraulic components and the gas strut 180. This device achieves multiple beneficial effects through its innovative structural design, including two-way buffering during opening and closing, reducing vibration and noise, eliminating the safety hazard of sudden door opening, extending service life, simplifying installation and maintenance, and flexible adjustment to adapt to different cabinet door weights and usage needs. The overall structural layout is reasonable, and the components work together to ensure the stability of the buffering effect while meeting the high-quality requirements of modern furniture hardware.
