[0025] The invention will be further described in detail below with reference to the accompanying drawings. A direct-push door opener is characterized in that: it includes a bottom shell 1 and a top cover 2, a receiving cavity 3 is provided between the bottom shell 1 and the top cover 2, an opening groove 4 is provided at the front end of the receiving cavity 3, a push rod 5 is telescopically installed in the receiving cavity 3 through the opening groove 4, a first slider 6 and a second slider 7 are also provided in the receiving cavity 3, and a linkage device is provided between the first slider 6 and the second slider 7, the linkage device driving the first slider 6 and the second slider 7 to move synchronously; An elastic device is provided between the first slider 6 or the second slider 7 and the accommodating cavity 3. The elastic device pushes the first slider 6 to move outward continuously, thereby pushing the push rod 5 outward. The second slider 7 is also hinged to a sliding hook 8. Correspondingly, a slide 81 is provided in the accommodating cavity 3. A locking channel 82 is provided at the tail of the slide 81. The sliding hook 8 slides on the slide 81 or the locking channel 82. A reset device is provided on the sliding hook 8. The reset device always pushes the sliding hook 8 to swing in the direction of disengaging from the locking channel 82. The tail of the push rod 5 presses against the front end of the first slider 6, and the first slider 6 pushes the push rod 5 outward through its front end. A guide device is also provided between the push rod 5 and the receiving cavity 3. The guide device limits the extension and retraction stroke and swing amplitude of the push rod 5. The push rod 5 is also provided with a hook device at its head. Correspondingly, a pull block 51 is installed on the cabinet door. The hook device hooks with the pull block 51 when the cabinet door is closed and separates from the pull block 51 when the cabinet door is opened. The tail of the push rod 5 is also provided with a push block 52, which presses against the sliding hook 8. The push block 52 pushes the sliding hook 8 to always move in the direction of the locking track 82, thereby forcing the sliding hook 8 to hook onto the locking track 82.

[0026] The linkage device is a gear 9 installed in the movable cavity. Correspondingly, racks 91 are provided on the first slider 6 and the second slider 7, and the racks 91 mesh with the gear 9.

[0027] The linkage device is a pulley 93 installed in the movable cavity. A pull rope 94 is provided on the first slider 6 and the second slider 7. The pull rope 94 passes around the pulley 93 and its two ends are connected to the first slider 6 and the second slider 7 respectively.

[0028] The elastic device is a tension spring 10 installed between the first slider 6 and the accommodating cavity 3. The tension spring 10 always pulls the first slider 6 outward.

[0029] The elastic device is a tension spring 10 installed between the second slider 7 and the accommodating cavity 3. The tension spring 10 always pulls the second slider 7 inward.

[0030] The guiding device consists of a guide post 31 and a guide groove 32 disposed in the accommodating cavity 3. Correspondingly, a sliding groove 53 and a guide pin 54 are provided on the side wall of the push rod 5. The guide post 31 is inserted into the sliding groove 53, and the guide pin 54 is inserted into the guide groove 32.

[0031] The guide post 31 is disposed in the opening slot 4, and the guide pin 54 is disposed at the tail of the push rod 5.

[0032] The reset device is a torsion spring 55. One support foot of the torsion spring 55 is supported on the sliding hook 8, and the other end is set in the receiving groove. The torsion spring 55 pushes the sliding hook 8 to swing in the direction of disengaging from the locking track 82.

[0033] The cavity 3 is also equipped with a buffer cylinder 33 and a reset slider 34. The reset slider 34 and the cavity 3 are equipped with a reset spring 35. The reset spring 35 always pulls the reset slider 34 inward. The reset slider 34 is hooked on the push rod 5, and the buffer cylinder 33 is supported at the tail of the push rod 5.

[0034] The hook device is a hook groove 56 set at the head of the push rod 5. Correspondingly, a connecting post 57 is provided on the pull block 51, and the opening slot 4 is snapped onto the connecting post 57 and connected to it.

[0035] like Figure 9 As shown, the linkage device is a lever 95 installed in the movable cavity. One end of the lever 95 is hinged to the first slider 6, and the other end is hinged to the second slider 7.

[0036] The lever 95 is hinged to the first slider 6 via a connecting rod 96. The other end of the lever 95 is provided with a sliding groove 97, and the second slider 7 is provided with a pin that is slidably hinged in the sliding groove.

[0037] like Figure 10 As shown, the linkage device is an arc-shaped sliding groove 98 set in the movable cavity. A drag chain 99 is slidably installed in the sliding groove 98. The two ends of the drag chain 99 are respectively hinged to the first slider 6 and the second slider 7.

[0038] Working principle: such as Figure 1 As shown, during installation, the main body of this door opener can be installed on the upper or lower surface of the cabinet 41, and the pull block 51 can be installed on the cabinet door 42. It exerts force on the cabinet door. Simultaneously, the connecting hinge 43 between the cabinet door and the cabinet body must be a reset-buffered hinge with a reset-closing function (a common market accessory).

[0039] like Figure 4 The diagram illustrates the operation of the door opener in this invention. When the cabinet door needs to be opened, the door is pressed inward. The door, via the pull block 51, presses the push rod 5 inward. As the push rod 5 moves inward, it pushes the second slider 7 inward. The second slider 7, through a linkage device, drives the first slider outward, thereby pushing the sliding hook 8 forward. Under the push of the reset device, the sliding hook is forced to separate from the locking track. This reset device can be a torsion spring, spring, or other elastic device that can generate elastic force to push the sliding hook away from the locking track. In this state, the second slider 7 loses its locking force. Under the action of the elastic device, the elastic device pushes the first and second sliders to move. The reaction force of the elastic device pushes the push rod 5 outward, opening the cabinet door, thus achieving the press-and-rebound opening of the cabinet door. When the user pulls the cabinet door outwards, the pulling force applied to the door drives the push rod to continue moving outwards via the pull block 51. The pull block 51 has a push block 52 at its tail, which presses against the sliding hook 8. As the push block 52 moves outwards, it pushes the sliding hook 8 towards the locking track 82. When the sliding hook reaches the locking track position, it forces the sliding hook 8 to engage with the locking track 8, compressing the reset device and storing energy. This forces the first and second sliders to reset the elastic device. The pulling force generated when the elastic device resets forces the sliding hook 8 to engage with the locking track 8 and prevents it from loosening.

[0040] As the cabinet door continues to open outward, the push rod 5 is guided by the guide post 31 and guide groove 32 set in the accommodating cavity 3, and the sliding groove 53 and guide pin 54 set on the side wall of the push rod 5. When the push rod 5 moves outward to its maximum outward stroke, the head of the push rod 5 will wobble, forcing the hook groove 56 of the head of the push rod 5 to separate from the connecting post 57 set on the pull block 51. At this time, the cabinet door can continue to open outward completely.

[0041] When the user needs to close the door: the cabinet door closes inward. When the closing angle of the cabinet door is less than the designed closing angle of the connecting hinge 43, the reset device inside the connecting hinge 43 will push the cabinet door to close automatically. When the cabinet door closes automatically, the connecting post 57 and the hook groove 56 collide again and hook each other. The automatic closing force of the cabinet door pushes the push rod back into the receiving cavity, thus realizing the automatic closing of the cabinet door. Compared with traditional door closers, the cabinet door can close automatically under the reset action of the hinge, so that the user does not need to manually operate it to the fully closed state. While facilitating user operation, it maintains the airtightness and aesthetics of the cabinet door after it is closed.

[0042] It should be noted that: Figure 4 , 5 As shown in Figures 6 and 7, the linkage device in this case is a gear 9 installed in the movable cavity. Correspondingly, racks 91 are provided on the first slider 6 and the second slider 7, and the racks 91 mesh with the gear 9. In this embodiment, the elastic device is a tension spring 10 installed between the first slider 6 and the accommodating cavity 3, and the tension spring 10 always pulls the first slider 6 outward. Simultaneously, the elastic device can also be a tension spring 10 installed between the second slider 7 and the accommodating cavity 3, and the tension spring 10 always pulls the second slider 7 inward. By selecting the direction of the applied elastic force, the elastic device can, under the action of the linkage device, push the first slider outward to rebound and push the push rod 5 away.

[0043] It should be noted that: Figure 7 As shown, when the linkage device is a pulley 93 installed in the movable cavity, and the first slider 6 and the second slider 7 are provided with pull ropes 94, which pass around the pulley 93 and are connected at both ends to the first slider 6 and the second slider 7 respectively, the elastic device is a tension spring 10 installed between the first slider 6 and the accommodating cavity 3. The tension spring 10 always pulls the first slider 6 outward. This pulley-type connecting device can effectively reduce the length of the slider. Compared with the first embodiment, its length can be smaller, which is beneficial to the development of product miniaturization.

[0044] It should be noted that: Figure 9 As shown, the linkage device is a lever 95 installed in the movable cavity. One end of the lever 95 is hinged to the first slider 6, and the other end is hinged to the second slider 7. Through the linkage of the lever, the first slider 6 and the second slider 7 can move in a linked manner.

[0045] It should be noted that: Figure 10 As shown, the linkage device is an arc-shaped sliding groove 98 disposed within the movable cavity. A drag chain 99 is slidably installed within the sliding groove 98, and both ends of the drag chain 99 are hinged to the first slider 6 and the second slider 7, respectively. During operation, the drag chain slides within the arc-shaped sliding groove 98, thereby driving the first slider 6 and the second slider 7 to perform linked movements.

[0046] like Figure 7 , 8 As shown, to prevent the push rod 5 from still protruding outwards after the cabinet door is opened, affecting aesthetics, a buffer cylinder 33 and a reset slider 34 are also provided in the receiving cavity 3. A reset spring 35 is installed in both the reset slider 34 and the receiving cavity 3, and the reset spring 35 constantly pulls the reset slider 34 inwards. Therefore, when the push rod separates from the pull block, the reset slider 34, under the action of the reset spring, pulls the push rod 5 inwards to reset, while the buffer cylinder slows down the push rod's retraction speed, preventing the push rod from hitting the slider and generating noise, thus making the door opener more stable and quieter. Therefore, compared with traditional door openers, the internal structure of this invention is simpler, with fewer moving parts, and higher working efficiency. At the same time, the simple and efficient mechanism can effectively reduce the difficulty of the production process, thereby reducing production costs and improving market competitiveness, and therefore can be widely promoted and used.
