Abstract
Description
Technical Field
[0001] This utility model relates to the field of electrical equipment bracket technology, and in particular to a floor-standing lifting bracket for products such as monitors and all-in-one computers, such as the VESA bracket. Background Technology
[0002] Current monitors and all-in-one PCs typically use lifting devices in conjunction with VESA brackets for easy height and angle adjustments. VESA (Video Electronics Standards Association) brackets include VESA components (such as VESA boards and VESA covers), which are used to secure the monitor. Current floor-standing lifting brackets usually employ gas springs or coil springs for lifting, with the main body consisting of a long extruded aluminum rod with a CNC lifting slot, or two extruded aluminum sleeves of different sizes. These are shipped as a single unit, consuming significant space in packaging. Furthermore, the four-bar linkage arms used in current market are often complex, limiting their application and making it difficult to meet users' needs for frequent repositioning. For example, the four-bar linkage hinge for LCD monitors disclosed in Chinese Utility Model Patent CN03251089.6 involves numerous parts, resulting in complex assembly processes, low assembly efficiency, and poor reliability. Utility Model Content
[0003] This utility model addresses the shortcomings of existing technologies by providing a linkage-type floor lifting support that has a simpler structure, more reasonable design, easier assembly and operation, higher efficiency, can be packaged separately, and can reduce the size of the shipping packaging.
[0004] To solve the above-mentioned technical problems, this utility model adopts the following technical solution: a linkage-type floor-mounted lifting bracket, comprising a base frame, a floor rod, a lifting assembly, and a VESA assembly. The floor rod is mounted on the base frame, the lifting assembly is mounted on the floor rod, and the VESA assembly is mounted on the front end of the lifting assembly. The base frame comprises longitudinal and transverse rods, which are interlocked and secured with screws. The floor rod comprises a lower and an upper rod, which are detachably assembled. The lifting assembly comprises a lower connecting rod and an upper connecting rod, which are parallel to each other and do not contact each other. A fixing head is installed at the top of the upper rod, and the upper and lower connecting rods are respectively assembled with the fixing head via pins to form a rotatable structure. Rotatable connectors are mounted at the front ends of the upper and lower connecting rods via pins, and the VESA assembly is fixedly assembled with the connectors.
[0005] Furthermore, the lower connecting rod is an upward-opening groove structure, and the upper connecting rod is a downward-opening groove structure. The upper and lower connecting rods are arranged with their openings facing each other. A tension spring is provided in the cavity between the upper and lower connecting rods. The front end of the tension spring is connected to a hook located at the front of the lower connecting rod, and the rear end is connected to a hook located at the rear of the upper connecting rod.
[0006] Furthermore, fixing ears are provided on both the front and rear ends of the upper and lower connecting rods, and recessed mounting slots are provided on both sides of the fixing head and both sides of the connector corresponding to the fixing ears, with the fixing ears respectively locked in the mounting slots; an outwardly protruding rear stop is formed on the upper edge of the mounting slot of the fixing head, and an outwardly protruding front stop is formed on the upper edge of the mounting slot of the connector, forming a stop and limiting structure for the front and rear fixing ears through the front and rear stops respectively.
[0007] Furthermore, a retaining plate is installed on the connector head, and the VESA assembly is assembled and fixed with the retaining plate.
[0008] Furthermore, the upper and lower rods are connected and fixed by a pair of connectors. The lower end of the connector is inserted into the lower rod, and the upper end is inserted into the upper rod. Screws are used to lock and fix the connector to the upper and lower rods.
[0009] Furthermore, both the longitudinal bar and the transverse bar are straight bars. A snap-fit connector is provided at the front end of the longitudinal bar, and a snap-fit interface is provided on the side at the middle position of the transverse bar. The snap-fit connector passes through the snap-fit interface and engages with the transverse bar for fixation. The snap-fit connector and the transverse bar are locked together by screws to form a T-shaped structure between the longitudinal bar and the transverse bar.
[0010] Furthermore, casters are installed at the tail end of the longitudinal bar and at both ends of the horizontal bar to allow the entire bracket to be moved easily. Once in position, the casters can be braked and parked.
[0011] Furthermore, the bottom surface of the longitudinal strut is fitted with a reinforcing cap to enhance the structural strength of the base frame and improve stability.
[0012] Furthermore, the fixing head has an inverted L-shaped structure with a docking part at its bottom. The docking part is inserted into the top of the upper rod, and the upper rod is locked and fixed to the docking part by screws.
[0013] This invention combines a connecting rod and a grounding rod, achieving product lifting while maintaining the independence of the main body and lifting structure. The lifting structure can be detached separately, and the main grounding rod can be disassembled into two sections. The chassis adopts a two-rod assembly structure, allowing users to assemble it themselves, significantly reducing packaging size. The connecting rod uses an upper and lower linkage structure, which significantly simplifies the structure compared to the traditional four-bar linkage, reduces the number of parts, lowers costs, and provides higher stability and easier adjustment.
