[0025] In order to make the objectives, technical solutions and advantages of the present invention more clearly understood, the present invention is further described in detail below in conjunction with specific embodiments.

[0026] like Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 and Figure 6 As shown, a buffer integrated push-button device comprises a push-button tube 1 installed in a cabinet body, a movement 3 is slidably installed inside the push-button tube 1, a sliding hole 17 is provided inside the movement 3, and a slow-release rubber sleeve 4 is sleeved on the outside of the movement 3, a push-button rod 2 is threadedly connected to one end of the movement 3, a limit plug 10 is clamped to one end of the push-button rod 2, and a door panel fixer 14 for connecting to a cabinet door is movably clamped inside the limit plug 10;

[0027] A connecting hook seat 6 is fixedly installed at the inner bottom end of the elastic tube 1, a spring 5 is connected between the connecting hook seat 6 and the movement 3, one end of the spring 5 is connected to the outside of the movement 3, and the other end of the spring 5 is sleeved on the outside of the connecting hook seat 6, a hook seat pressing block 8 is detachably installed on one side of the connecting hook seat 6, and a C-shaped hook 7 is movably installed between the connecting hook seat 6 and the hook seat pressing block 8, and the C-shaped hook 7 corresponds to the sliding hole 17;

[0028] The door panel holder 14 includes a fixing seat plate 12 , a cross hole 18 is formed on one side of the middle of the fixing seat plate 12 , an elastic fixing head 11 is movably engaged inside the cross hole 18 , and one end of the elastic fixing head 11 is engaged inside the limit plug 10 .

[0029] In this embodiment, the elastic fixing head 11 is connected with the limit plug 10 to close the cabinet door and the cabinet body. After the limit plug 10 at the top of the push rod 2 is squeezed by the door panel fixer 14, the push rod 2 moves in the push tube 1, so that the C-shaped hook 7 moves in the sliding hole 17 of the clamping seat 19, until the C-shaped hook 7 is disengaged from the sliding hole 17 in the clamping seat 19, and is moved outward by the force pushed out by the spring 5. The slow-out rubber sleeve 4 outside the movement 3 moves at the same time until it reaches the inner end of the push tube 1 and is limited. At this time, the slow-out rubber sleeve 4 moves inside the movement 3, so that the push rod 2 is slowly ejected, and finally the elastic fixing head 11 is separated from the limit plug 10, and the cabinet body and the cabinet door are opened.

[0030] As an implementation method, Figure 2 and Figure 5 As shown, the movement 3 includes a trapezoidal table 16, and threaded columns 15 and a clamping seat 19 are fixedly installed at both ends of the trapezoidal table 16. The sliding hole 17 is opened inside the clamping seat 19, and the opening of the sliding hole 17 is arranged in a funnel shape, and a V-shaped protrusion 24 is arranged inside the sliding hole 17. The V-shaped protrusion 24 divides the inside of the sliding hole 17 to form a sliding path, and the slow-out rubber sleeve 4 is sleeved on the outside of the trapezoidal table 16.

[0031] In this embodiment, the movement 3 is formed by combining a trapezoidal platform 16, a threaded column 15 and a clamping seat 19. The threaded column 15 strengthens the connection with the push rod 2 and is detachable. The C-shaped hook 7 is movable within the sliding path, and the C-shaped hook 7 is clamped by a V-shaped protrusion 24. The clamping seat 19 corresponds to the connecting hook seat 6, and the trapezoidal platform 16 corresponds to the slow-release rubber sleeve 4. The whole is easy to assemble.

[0032] As an implementation method, Figure 3 As shown, the clamping seat 19 is a semi-cylindrical body, and blocks for limiting the swing of the C-shaped hook 7 are respectively arranged on both sides of the clamping seat 19 .

[0033] In this embodiment, the stoppers on both sides of the clamping seat 19 are used to limit the swing of the C-shaped hook 7, so that the C-shaped hook 7 can slide in the clamping seat 19, which is convenient for limiting the door panel fixer 14.

[0034] As an implementation method, Figure 2 and Figure 5 As shown, the inside of the slow-release rubber sleeve 4 is provided with a through hole for accommodating the trapezoidal platform 16 , the thickness of the through hole is smaller than the thickness of the sliding hole 17 , and the outside of the slow-release rubber sleeve 4 is provided with multiple groups of oil storage tanks 20 .

[0035] In this embodiment, when the push-pull rod 2 moves inward, the slow-out rubber sleeve 4 will easily move inward at a place with a small slope due to the trapezoidal structure of the trapezoidal platform 16. Conversely, when the push-pull rod 2 is ejected, the slow-out rubber sleeve 4 will slowly eject at a place with a large slope. After the slow-out rubber sleeve 4 is limited at the end of the push-pull tube 1, it will be expanded at the place with a large slope, and then generate corresponding resistance to reduce the elastic force of the spring 5, so that the push-pull rod 2 and the limiting plug 10 will slowly eject.

[0036] As an implementation method, Figure 2 , Figure 3 and Figure 5 As shown, a latch pin 9 is installed between the connecting hook seat 6 and the spring-action tube 1 , and the connecting hook seat 6 and the clamping seat 19 are arranged corresponding to each other.

[0037] In this embodiment, the position between the connecting hook seat 6 and the spring tube 1 is fixed by the pin 9, and the semicircular setting of the connecting hook seat 6 and the clamping seat 19 reduces the distance between the connecting hook seat 6 and the clamping seat 19, making it easier for the C-shaped hook 7 to slide on the slider in the clamping seat 19.

[0038] As an implementation method, Figure 6 As shown, the inner wall of the push rod 2 and the outside of the limit plug 10 are respectively provided with matching limit blocks 22 and limit grooves 23, and the limit plug 10 is provided with a positioning hole 21 on the side facing the door panel fixer 14, and the interior of the positioning hole 21 is movably engaged with one end of the elastic fixing head 11.

[0039] In this embodiment, the spring rod 2 and the limit plug 10 are clamped together by the limit block 22 and the limit groove 23, which is convenient for assembly and maintenance, and the positioning hole 21 in the limit plug 10 is clamped together with the elastic fixing head 11 to facilitate the closing of the cabinet door and the cabinet body.

[0040] As an implementation method, Figure 1 and Figure 3 As shown, a double-sided adhesive tape is provided on one side of the door panel fixer 14 , and a fixing screw 13 is installed through the interior of the door panel fixer 14 .

[0041] The elastic fixing head 11 is a combination of a cone and a sphere, and the fixing seat plate 12 is a plastic component.

[0042] In this embodiment, the toughness of the cross hole 18 in the fixed seat plate 12 is utilized to allow the elastic fixing head 11 to have a certain amount of movable space in the fixed seat plate 12, so that it can automatically straighten itself when the user positions it incorrectly. In addition, the elastic fixing head 11 and the limit plug 10 have a good mute effect under cooperation, and the buffering force is greater when closing and opening the door, and the service life can also be greatly improved.

[0043] Working principle: when in use, after installing double-sided tape on one side of the door panel fixer 14, it is installed on the cabinet door with the fixing screw 13, and the push-spring tube 1 is installed in the cabinet body hole, and the limit plug 10 on one side of the push-spring rod 2 is clamped with the door panel fixer 14, and the door panel fixer 14 is pressed to the bottom first, and the door panel fixer 14 drives the limit plug 10 and the push-spring rod 2 to move, and the movement 3 at the bottom end of the push-spring rod 2 slides inside the push-spring tube 1, and the spring 5 is gradually compressed. At the same time, when the push-spring rod 2 moves inward, the slow-out rubber sleeve 4 moves inward easily due to the trapezoidal structural inclination of the trapezoidal platform 16, until the C-shaped hook 7 in the connecting hook seat 6 is clamped into the sliding hole 17 of the clamping seat 19, and in the sliding path in the sliding hole 17, the internal V-shaped protrusion 24 clamps the C-shaped hook 7, and the cabinet body and the cabinet door are closed;

[0044] When the limit plug 10 at the top of the push-spring rod 2 is squeezed by the door panel fixer 14 again, the C-shaped hook 7 in the connecting hook seat 6 moves in the sliding hole 17 of the clamping seat 19 until the C-shaped hook 7 is disengaged from the sliding hole 17 in the clamping seat 19, and the spring 5 drives the movement 3 and the slow-out rubber sleeve 4 to move outward under the elastic force, and then the slow-out rubber sleeve 4 is moved outward under the inner inclined surface of the trapezoidal platform 16 by the force pushed out by the spring 5 until it is limited by the inner end of the push-spring tube 1. At this time, the size of the slow-out rubber sleeve 4 at the place with a large inclination of the trapezoidal platform 16 will be enlarged, thereby increasing the ejection resistance of the push-spring rod 2, causing the push-spring rod 2 and the limit plug 10 to slowly eject, and finally the elastic fixing head 11 is separated from the limit plug 10, and the cabinet body and the cabinet door are opened.
