Description

Technical Field

[0001] The utility model relates to the technical field of gas supports, in particular to a bidirectional buffer gas support device. Background Art

[0002] Gas struts are widely used in furniture products. Usually, the gas struts are hinged between the cabinet door and the cabinet body, and a hinge is also hinged between the cabinet door and the cabinet body. Under the action of the hinge, the cabinet door can be flipped open. The function of the gas strut is to keep the cabinet door open when it is opened.

[0003] Conventionally, the gas strut consists of a slidingly connected cylinder and a piston rod. The cylinder is filled with inert gas. In order to achieve a buffering function during the closing process of the cabinet door, the cylinder and the piston rod are also provided with a damping structure. During the closing process of the cabinet door, the gas passes through the damping structure, which can make the cabinet door close slowly.

[0004] However, the damping effect of the damping structure inside the gas strut is poor, and there is a lot of noise when the cabinet door is closed. Moreover, the buffering function cannot be achieved when the cabinet door is opened, resulting in large vibrations when the cabinet door is opened or closed, which can easily damage the gas strut and the hinge structure, resulting in a short service life of the cabinet door.

For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0031] A bidirectional buffer gas support device according to an embodiment of the utility model is described below in conjunction with the accompanying drawings.

[0032] Reference Figure 1 A bidirectional buffer gas support device according to an embodiment of the utility model includes a gas support assembly and a buffer assembly.

[0033] The structure of the gas strut assembly includes a gas strut rod 100, a connecting head 110 and a support seat 120. One end of the gas strut rod 100 is rotatably connected to the cabinet body, and the other end of the gas strut rod 100 is fixedly connected to the connecting head 110. The connecting head 110 is rotatably connected to the support seat 120, and the support seat 120 is fixedly arranged on the cabinet door.

[0034] It is understandable that when the cabinet door is opened, the gas strut 100 can support the cabinet door.

[0035] In the structure of the structural buffer assembly, a first damper 130 and a second damper 140 are included. The first damper 130 and the second damper 140 are circumferentially distributed along the rotation axis formed by the connecting head 110 and the supporting seat 120. The first damper 130 is arranged on the connecting head 110, and the second damper 140 is arranged on the supporting seat 120.

[0036] Therefore, the distribution of the first damper 130 and the second damper 140 is reasonable, which is conducive to reducing the volume of the gas strut device. The first damper 130 and the second damper 140 can achieve a buffering effect without designing a complex damping structure inside the gas strut rod 100, thereby reducing the noise during the opening or closing process of the cabinet door. Moreover, the gas strut structure is simple, which reduces the manufacturing cost and improves the competitiveness of the product.

[0037] Specifically, the support seat 120 is provided with an abutment member 150, which is used to abut the first damper 130 to enable the first damper 130 to telescope and buffer. The connecting head 110 is provided with a rotating member 160, which is used to abut the second damper 140 to enable the second damper 140 to telescope and buffer.

[0038] Therefore, refer to Figure 5 During the closing process of the cabinet door, the gas strut 100 rotates, so that the rotating member 160 rotates along with the connecting head 110, and the rotating member 160 abuts against the first damper 130, so that the first damper 130 itself expands and contracts, so that the cabinet door closes slowly; Figure 4 During the opening process of the cabinet door, the gas strut rod 100 rotates, the abutment piece 150 abuts against the second damper 140, causing the second damper 140 itself to expand and contract, so that the cabinet door opens slowly. Therefore, compared with the traditional one-way buffering gas strut device, the utility model can achieve buffering during the opening or closing process of the cabinet door, reduce the vibration of the cabinet door, and increase the service life of the cabinet door.

[0039] In some embodiments of the present invention, the connector 110 is provided with a receiving channel 170 , which extends along the length direction of the gas strut 100 . The first damper 130 is disposed in the receiving channel 170 and can be retracted along the extending direction of the receiving channel 170 .

[0040] It can be understood that the length directions of the first damper 130 and the gas strut rod 100 are consistent, that is, the first damper 130 and the gas strut rod 100 are arranged side by side, which is beneficial to reducing the volume of the gas strut device and is beneficial to the abutment between the first damper 130 and the abutment member 150, which can effectively achieve buffering.

[0041] In order to change the damping force of the first damper 130, refer to Figure 3 , the connecting head 110 can be threadedly connected with the first adjusting bolt 180, the first adjusting bolt 180 is located at the end of the storage channel 170 away from the support seat 120, and the end of the first adjusting bolt 180 abuts against the first damper 130. Therefore, by rotating the first adjusting bolt 180, the first damper 130 can be extended and retracted to change its own length, thereby changing the damping force of the first damper 130, and further achieving the effect of changing the slow opening of the cabinet door.

[0042] It should be noted that a mounting nut 310 is disposed in the receiving channel 170 , and the mounting nut 310 is threadedly connected to the first adjusting bolt 180 , so that the first adjusting bolt 180 can achieve an adjusting function.

[0043] In a further embodiment of the present invention, referring to Figure 2 and Figure 3 The connector 110 is clamped with a sleeve 190, which is located in the receiving channel 170. The first damper 130 is slidably disposed in the sleeve 190. A boss 200 is disposed on the radial outer surface of the first damper 130, and the boss 200 abuts against one end of the sleeve 190 away from the first adjusting bolt 180.

[0044] It should be noted that when installing the first damper 130, the ring 190 can be firstly mounted on the first damper 130, and then the ring 190 can be snapped into the receiving channel 170 of the connector 110. Thus, the abutment between the ring 190 and the boss 200 can prevent the first damper 130 from falling off from the receiving channel 170.

[0045] Furthermore, during the abutment and buffering process between the abutting member 150 and the first damper 130 , the first damper 130 can slide along the axial direction of the collar 190 .

[0046] Specifically, a buckle is disposed on the outer periphery of the collar 190 , and a buckle position is disposed inside the receiving channel 170 , into which the buckle can be inserted, so that the collar 190 is fixed in the receiving channel 170 .

[0047] In a further embodiment of the utility model, a first spring 210 is provided in the receiving channel 170 , and the first spring 210 is located on the side of the collar 190 close to the first adjusting bolt 180 . The first spring 210 is used to drive the first damper 130 to slide so that the boss 200 abuts against the collar 190 .

[0048] Therefore, when the first adjusting bolt 180 adjusts the damping force of the first damper 130 , the first spring 210 can make the first damper 130 slide, ensuring that the boss 200 and the collar 190 are in contact with each other, thereby ensuring that the first damper 130 and the contact member 150 are in effective contact and buffering.

[0049] In some embodiments of the present invention, referring to Figure 2 and Figure 3 The support seat 120 is provided with a mounting groove 220 , and the second damper 140 is disposed in the mounting groove 220 and can be extended and retracted along the length direction of the mounting groove 220 .

[0050] Therefore, the second damper 140 is housed in the mounting groove 220 , making the structure of the gas strut device more compact, which helps to reduce the volume of the gas strut device.

[0051] In a further embodiment of the present invention, referring to Figure 2 The support seat 120 has two vertical plates 230 arranged opposite to each other, a mounting groove 220 is formed between the two vertical plates 230, a support shaft 240 is connected between the two vertical plates 230, and the connector 110 is rotatably disposed on the support shaft 240 and is located in the mounting groove 220.

[0052] It should be noted that the vertical plate 230 is provided with a support hole, and the support shaft 240 is installed in the support hole, and one of the two vertical plates 230 is connected to the support shaft 240 by snapping, so that the support shaft 240 is more convenient to fix.

[0053] Therefore, the second damper 140 can be placed in the installation groove 220 first, and then the support shaft 240 can be installed in the support hole, so that the assembly of the gas support device is easier.

[0054] In order to prevent the second damper 140 from detaching from the installation groove 220, buckles 250 can be provided on both sides of the abutment 150, and a slot 260 is provided on the side of the vertical plate 230 away from the installation groove 220. The buckle 250 engages with the slot 260, so that the abutment 150 can limit the second damper 140.

[0055] Moreover, the connecting head 110 is provided with an arc groove 320, which extends along the rotation direction of the connecting head 110, and the cross-section of the arc groove 320 is semicircular. Therefore, the arc groove 320 can adapt to the radial outer surface of the second damper 140 to further limit the second damper 140 and prevent the second damper 140 from detaching from the mounting groove 220.

[0056] In order to change the damping force of the second damper 140, the support seat 120 can be threadedly connected with a second adjusting bolt 270, the end of the second adjusting bolt 270 abuts against the second damper 140 and is located at the end of the mounting groove 220 away from the rotating member 160, and the second damper 140 is provided with a second spring 280 near the end of the second adjusting bolt 270, and the second spring 280 is used to drive the second damper 140 close to the rotating member 160.

[0057] Therefore, by rotating the second adjusting bolt 270, the second damper 140 can be extended and retracted to change its own length, thereby changing the damping force of the second damper 140, and further achieving the effect of changing the slow closing of the cabinet door.

[0058] When the second adjusting bolt 270 adjusts the damping force of the second damper 140 , the second spring 280 can make the second damper 140 close to the rotating member 160 , thereby ensuring that the second damper 140 and the rotating member 160 are in effective contact and buffering.

[0059] In order to prevent the support seat 120 from interfering with the bolt head of the second adjusting bolt 270 , the support seat 120 is provided with a semicircular groove 330 , which can accommodate the bolt head of the second adjusting bolt 270 .

[0060] In a further embodiment of the present utility model, the support seat 120 is provided with a limiting groove 290 , a first nut 300 is provided in the limiting groove 290 , and the first nut 300 is threadedly connected to the second adjusting bolt 270 .

[0061] It should be noted that the first nut 300 is square in shape, and the limiting groove 290 is also square in shape. The first nut 300 can be placed in the limiting groove 290 from the bottom of the support seat 120, thereby making the first nut 300 easy to install.
