Technical Field
[0001] The utility model relates to the technical field of switch devices, in particular to a press rebounder. Background Art
[0002] Some existing furniture cabinet doors do not have handles installed, which can make the cabinet body look more simple and beautiful.
[0003] Usually, cabinet doors without handles are opened by pressing a rebounder, which is installed inside the cabinet body. When in use, pressing the cabinet door can extend the telescopic rod of the rebounder to open the cabinet door.
[0004] In the related art, the telescopic rod of the rebounder is slidably set on the shell, and the telescopic rod is driven to extend out of the shell by a spring. In order to control the extreme position of the telescopic activity of the telescopic rod, a pull hook is hinged on the side wall of the shell, and an annular guide groove is set on the side wall of the telescopic rod. The pull hook moves in the annular guide groove and can be engaged and positioned with the positioning part of the annular guide groove, thereby limiting the extension position and retraction position of the telescopic rod.
[0005] When installing the hook, first insert the hook at one end of the hook into the mounting hole of the shell, and then insert the hook at the other end of the hook into the annular guide groove. However, the annular guide groove is a closed structure, making it difficult to insert the hook into the annular guide groove, and the hook is prone to deformation. Utility Model Content
[0006] The present invention aims to solve at least one of the technical problems in the prior art. To this end, the present invention provides a push-rebound device that is easy to install, can reduce assembly difficulty, and reduce the occurrence of defective products.

[0031] A press rebounder according to an embodiment of the present utility model will be described below with reference to the accompanying drawings.
[0032] Reference Figure 1 , the utility model aims to provide an embodiment of a press rebounder.
[0033] A press rebounder according to an embodiment of the present invention includes a pop-up assembly, a swing hook 130 , a limiting structure, and a guiding structure.
[0034] Specifically, the pop-up assembly includes a housing 100, a push rod 110 slidably arranged on the housing 100, and a spring 120 that drives the push rod 110 to slide. The push rod 110 is used to push the cabinet door; a swing hook 130 is arranged between the housing 100 and the push rod 110, one end of the swing hook 130 is rotatably connected to the housing 100, and the other end of the swing hook 130 is slidably connected to the push rod 110; Figure 3 The limiting structure is provided on the housing 100, and has an accommodating groove 140 for accommodating the swing of the swing hook 130. Two protrusions 150 are provided on one side wall of the accommodating groove 140. The swing hook 130 is arranged between the two protrusions 150 to limit the extreme position of the swing of the swing hook 130; the guiding structure is provided on the push rod 110, and has an insertion groove 160 and an annular groove 170 connected to the insertion groove 160. The free end of the swing hook 130 is provided with a hook 180, and the hook 180 can be inserted into the insertion groove 160 from the outside of the push rod 110, so that the hook 180 can move along the annular groove 170 to limit the sliding position of the push rod 110.
[0035] In some embodiments of the present invention, a collar 190 is provided at one end of the swing hook 130 away from the hook 180 , and a rotating shaft portion 200 is provided on the side wall of the accommodating groove 140 , and the collar 190 can be rotatably mounted on the rotating shaft portion 200 .
[0036] It is understandable that when the swing hook 130 is installed, the collar 190 is inserted into the shaft portion 200 so that the swing hook 130 can be swingably arranged in the receiving groove 140 , and at the same time, the receiving groove 140 limits the swing direction of the swing hook 130 .
[0037] In some embodiments of the present invention, referring to Figure 4 The accommodating groove 140 is provided with a ridge 210 , and the ridge 210 and the convex portion 150 are respectively arranged on two opposite side walls of the accommodating groove 140 . When the swing hook 130 swings, the ridge 210 abuts against the swing hook 130 to limit the swing direction of the swing hook 130 .
[0038] It should be noted that the protrusion 150 and the ridge 210 are arranged in sequence along the sliding direction of the push rod 110. After the swing hook 130 enters between the two protrusions 150, the ridge 210 can abut against the swing hook 130, which can prevent the swing hook 130 from escaping from between the two protrusions 150, ensuring the accurate swing position of the swing hook 130, so that the swing hook 130 can accurately enter the insertion groove 160 through the hook 180.
[0039] In some embodiments of the present invention, the protrusion 150 is a cylindrical structure.
[0040] The cylindrical protrusion 150 has a smaller structure, and the swing hook 130 can be made of elastically deformable metal material. Therefore, when the swing hook 130 enters between the two protrusions 150, the contact area between the swing hook 130 and the protrusion 150 is small, and only a slight elastic deformation occurs. In other words, the swing hook 130 is not easy to plastically deform during installation, and it also makes it easier to set the swing hook 130 between the two protrusions 150.
[0041] In some embodiments of the present invention, the accommodating groove 140 is provided with an avoidance hole 220, which accommodates the hook 180 extending out of the accommodating groove 140. Therefore, when the swing hook 130 swings, the hook 180 can swing with the swing hook 130, so that the hook 180 can penetrate into the insertion groove 160 and the annular groove 170.
[0042] In some embodiments of the present invention, the insertion groove 160 is V-shaped, and the groove width of the insertion groove 160 is gradually reduced in the direction close to the annular groove 170. Therefore, the insertion groove 160 can guide the hook 180 into the annular groove 170, ensuring that the hook 180 moves in the annular groove 170 along a certain direction.
[0043] In some embodiments of the present invention, a buckle 230 is provided inside the annular groove 170 , and the buckle 230 is provided away from the insertion groove 160 . The hook 180 is buckled with the buckle 230 to prevent the spring 120 from driving the push rod 110 out.
[0044] It is understandable that when the push rod 110 is in the retracted state, the hook 180 is engaged with the buckle position 230, which can prevent the spring 120 from driving the push rod 110 out, and prepare for pressing the push rod 110 to pop out.
[0045] In some embodiments of the present invention, the housing 100 is provided with a pop-up channel 240 extending from the inside to the outside, the pop-up channel 240 accommodates the passage of the push rod 110, and limiting edges 250 are provided on both horizontal sides of the pop-up channel 240. The push rod 110 is provided with an abutment portion 260, which abuts against the limiting edge 250 to prevent the push rod 110 from detaching from the housing 100.
[0046] It is understandable that after the spring 120 drives the push rod 110 to pop out from the pop-up channel 240, the limiting edge 250 can contact the abutment portion 260 of the push rod 110 to prevent the push rod 110 from separating from the housing 100, thereby limiting the pop-up position of the push rod 110.
[0047] In some embodiments of the present invention, referring to Figure 2 The housing 100 is provided with a guide rod 280 , the push rod 110 is provided with a guide sleeve 270 , the guide sleeve 270 is slidably set on the guide rod 280 , and the spring 120 is sleeved on the guide rod 280 so that the spring 120 can drive the guide sleeve 270 to slide along the guide rod 280 .
[0048] Therefore, the spring 120 drives the guide sleeve 270 to slide along the guide rod 280, so that the push rod 110 can slide horizontally and pop out, ensuring that the push rod 110 slides smoothly.
[0049] In some embodiments of the present invention, a damper 290 is coaxially provided on the push rod 110 , and the damper 290 is used to slow down the ejection speed of the push rod 110 .
[0050] Therefore, when the spring 120 drives the push rod 110 to pop out, the damper 290 can slow down the pop-out speed of the push rod 110, thereby preventing the push rod 110 from contacting the cabinet door and generating loud noise.
[0051] The working principle of the present invention is as follows: when the push rod 110 slides and retracts into the ejection channel 240, the spring 120 is in a compressed state. Figure 5 The swing hook 130 can accurately penetrate the open structure insertion groove 160 from the outside of the push rod 110 through the hook 180, and then move clockwise along the annular groove 170. Figure 6 When the hook 180 is engaged with the buckle 230, it can prevent the spring 120 from driving the push rod 110 out. By pressing the push rod 110, the spring 120 can drive the push rod 110 to extend out of the pop-up channel 240 to open the cabinet door. In addition, the limiting edge 250 can contact the abutment portion 260 of the push rod 110 to prevent the push rod 110 from separating from the housing 100.
[0052] Throughout this specification, references to terms such as "one embodiment, some embodiments, exemplary embodiments, examples, specific examples, or some examples" indicate that the specific features, structures, materials, or characteristics described in conjunction with that embodiment or example are included in at least one embodiment or example of the present invention. In this specification, illustrative uses of these terms do not necessarily refer to the same embodiment or example.
