Description

Technical Field

[0001] The utility model belongs to the technical field of brackets and relates to a bracket base for perforated installation. Background Art

[0002] Currently, the mainstream design for installing a perforated monitor stand is to drill a hole on the desktop, and then pass the screw through the monitor base and the desktop mounting hole in sequence, and then pass through the splint and nut at the bottom of the desktop and rotate the nut to fix it.

[0003] For example, the electronic device bracket disclosed in Chinese patent (CN204254193U) uses a fixed clamping device. When in use, a hole is drilled on the desktop or other selected fixed position, and the pressure plate 4 is clamped under the desktop or other selected fixed position. Then, the adjusting screw 3 is passed through the hole in the desktop and then through the adjusting screw hole 7; then the adjusting screw 3 is rotated to make the pressure plate 4 and the base 1 relatively close until the desktop is locked between the pressure plate 4 and the ground of the base 1.

[0004] According to the clamping device described above, the length of the adjusting screw is too long, and the pressure plate or the adjusting screw needs to be rotated multiple times to tighten the product, resulting in low product installation efficiency and relatively poor user experience.

DETAILED DESCRIPTION

[0032] The following are specific embodiments of the present invention and the accompanying drawings to further describe the technical solution of the present invention, but the present invention is not limited to these embodiments.

[0033] It should be noted that all directional indications (such as up, down, left, right, front, back, etc.) in the embodiments of the present invention are only used to explain the relative position relationship, movement status, etc. between the various components under a certain specific posture (as shown in the accompanying drawings). If the specific posture changes, the directional indication will also change accordingly.

[0034] like Figures 1 to 6 As shown, the utility model provides a perforated mounting bracket base, comprising:

[0035] The base 20 can contact a surface of the object 10 to be connected;

[0036] The screw member 30 is connected to the base 20 and can pass through the object to be connected 10; the base 20 limits the rotation of the screw member 30;

[0037] The connecting member 40 can contact the other surface of the object to be connected 10; a first connecting hole 41 is provided on the connecting member 40, and the first connecting hole 41 includes an intersecting first axis L1 and a second axis L2. The threaded member 30 slides with the connecting member 40 along the first axis L1 so that the connecting member 40 can quickly approach or move away from the object to be connected 10; the threaded member 30 is threadedly engaged with the connecting member 40 along the second axis L2 so that the connecting member 40 can tighten or loosen the object to be connected 10, and the threaded member 30 can switch between sliding engagement and threaded engagement.

[0038] It is worth mentioning that when the object to be connected 10 is set horizontally, the base 20 and the connecting member 40 are respectively arranged on the upper and lower sides of the object to be connected 10; when the object to be connected 10 is set vertically, the base 20 and the connecting member 40 are respectively arranged on the front and back sides of the object to be connected 10, wherein the object to be connected 10 can be a table top, at this time, the base 20 is located on the front of the table top, and the connecting member 40 is located on the back of the table top, and the base 20 can be used as a base when connected to a display device.

[0039] The present invention provides a perforated mounting bracket base, in which the first axis L1 on the first connecting hole 41 enables the connecting member 40 to quickly approach or move away from the object to be connected 10, and the second axis L2 on the first connecting hole 41 can lock or loosen the object to be connected 10, thereby speeding up the disassembly and assembly efficiency of the product without the need for a lengthy threaded stroke to lock or loosen the object to be connected 10.

[0040] It is further pointed out that the wall of the first connecting hole 41 is provided with a smooth surface and a threaded surface. The smooth surface is provided around the first axis L1 to form a smooth hole 411, and the threaded surface is provided around the second axis L2 to form a threaded hole 412. A channel is provided between the smooth hole 411 and the threaded hole 412 for the threaded member to switch between the smooth hole 411 and the threaded hole 412. The first axis L1 is an inclined axis, the second axis L2 is a vertical axis, and the first axis L1 intersects the second axis L2. The existence of the channel makes the smooth hole 411 and the threaded hole 412 incomplete, that is, part of the smooth hole 411 and the threaded hole 412 is missing due to the channel. The smooth hole 411 refers to the surface with a smooth inner wall.

[0041] It is worth mentioning that the intersection angle between the first axis L1 and the second axis L2 is greater than 0° and less than 45°, and the first connecting hole 41 is a through hole penetrating the connecting member 40 .

[0042] In addition, when assembling the product, the light hole 411 on the connecting member 40 is first plugged into the threaded member 30. At this time, the connecting member 40 is arranged obliquely, and the axial direction of the light hole 411 is arranged in the same direction as the axial direction of the threaded member 30. As the connecting member 40 continues to approach the object to be connected 10, when the connecting member 40 contacts the object to be connected 10, the connecting member 40 is adjusted so that the threaded member 30 enters the threaded hole 412 from the light hole 411 area. At this time, the axial direction of the threaded hole 412 is arranged in the same direction as the axial direction of the threaded member 30. Then, the connecting member 40 is rotated so that the connecting member 40 and the object to be connected 10 are abutted against each other, completing the assembly of the product.

[0043] According to the above assembly method, in the initial stage, the screw member 30 is engaged with the light hole 411 on the connecting member 40, so there is no thread engagement between the two, allowing the connecting member 40 to move quickly. When the connecting member 40 contacts the object 10 to be connected, the screw member 30 is engaged with the threaded hole 412 on the connecting member 40, and the connecting member 40 is rotated so that the connecting member 40 and the object 10 are abutted. Therefore, compared with the case where the screw member 30 is initially threadedly engaged with the threaded hole 412 on the connecting member 40 until the connecting member 40 and the object 10 are abutted, the assembly time is greatly shortened, thereby improving assembly efficiency.

[0044] Preferably, the connecting member 40 is arranged in a stepped shape, including a first step section 42 and a second step section 43 , and the diameter of the first step section 42 is smaller than the diameter of the second step section 43 .

[0045] Preferably, a first limiting portion 31 is provided on one end of the threaded member 30 close to the base 20 , and the base 20 is provided with a second limiting portion 21 . The first limiting portion 31 cooperates with the second limiting portion 21 to limit the rotation of the threaded member 30 .

[0046] It is further pointed out that the first limiting portion 31 includes at least one first limiting surface 311 , and the second limiting portion 21 includes at least one second limiting surface 211 , and the first limiting surface 311 and the second limiting surface 211 are offset against each other.

[0047] In this embodiment, a stopper is provided between the threaded member 30 and the base 20 because the abutment between the connector 40 and the object 10 to be connected is achieved through a threaded engagement between the connector 40 and the threaded member 30. Therefore, during the rotation of the connector 40, the threaded member 30 must remain stationary relative to the connector 40; otherwise, the threaded engagement between the two will not be achieved. To prevent the threaded member 30 from rotating during the rotation of the connector 40, one approach is to use an external tool, such as a screwdriver, to prevent the threaded member 30 from rotating, or to rotate the threaded member 30 in a direction opposite to that of the connector 40. Another approach is to provide a stopper between the threaded member 30 and the base 20 to form a stopper structure. The stopper prevents the threaded member 30 from rotating relative to the base 20 during the rotation of the connector 40. In this embodiment, a cube is provided at the end of the threaded member 30, and a groove of the same size and shape is provided in the base 20, forming a stopper.

[0048] Therefore, in order to achieve tool-free installation and convenience of product assembly, it is preferred to adopt the second method described above, that is, to set a limit portion between the screw member 30 and the base 20 to limit the circumferential rotation of the screw member 30.

[0049] Preferably, a splint 50 is further included, and a second connecting hole 51 for the threaded member 30 to pass through is provided on the splint 50. When the product is assembled, the object to be connected 10 is clamped between the base 20 and the splint 50, and the splint 50 is clamped between the object to be connected 10 and the connecting member 40.

[0050] In this embodiment, by providing the splint 50, the contact area between the connector 40 and the object 10 to be connected can be indirectly increased, thereby increasing the fastening force between the connector 40 and the object 10 to be connected, thereby ensuring the stability of the product during use.

[0051] Further preferably, the assembly direction of the splint 50 is recessed downward to form a first cavity 52 , and the second connection hole is provided on the bottom of the first cavity 52 , wherein the provision of the first cavity 52 can reduce the weight of the splint 50 .

[0052] Preferably, the base 20 is recessed downward in the assembly direction to form a second cavity 22 , and the second cavity 22 accommodates one end of the screw member 30 .

[0053] In this embodiment, by providing a second cavity 22 on the base 20, the end of the screw member 30 can be hidden in the second cavity 22. On the one hand, it can improve the aesthetics of the entire product appearance, and on the other hand, it can avoid interference with the screw member 30 when the display is installed on the base 20.

[0054] Preferably, a cover 60 is further included, and the cover 60 forms a nested fit with the second cavity 22, wherein the cavity opening of the second cavity 22 is sealed by the cover 60, and the end of the threaded member 30 close to the bottom of the second cavity 22 is arranged in the cover 60.

[0055] In this embodiment, by providing the cover 60 , the end of the screw member 30 can be further covered, thereby further improving the aesthetic appearance of the product.
