Description

Telescopic floor stand Technical Field The invention relates to the field of brackets, in particular to a telescopic floor bracket. Background With the popularity of electronic devices, such as tablet computers, cell phones, displays, etc., there is an increasing demand for holders that can flexibly support these devices. The floor support is free from being fixed on a wall surface or a tabletop, can be freely moved and placed, and is widely applied to scenes such as home, office, business display and the like. However, existing floor stands still have shortcomings in height adjustment, cross arm extension and hover stability. Conventional floor stands typically employ a telescoping construction that is highly locked by a knob or jackscrew. The adjusting mode is complex in operation, needs two hands to match, is not easy to control locking force, and is easy to fall off or difficult to lock. Meanwhile, in order to meet the requirements of different use heights, a plurality of adjustment gears are often required to be set, but the adjustment process is not smooth enough, and the user experience is poor. In addition, the cross arm of the existing floor stand is supported by adopting a gas spring or a common spiral spring. The air spring has higher cost and air leakage risk, and the common spiral spring is difficult to provide constant supporting force in the whole stroke, so that the cross arm has uneven hand feeling in the lifting process, and stable hovering at any position is difficult to realize. Therefore, we propose a telescopic floor stand to solve the above problems. Disclosure of Invention In order to solve the technical problems, the invention provides a telescopic floor support. The invention provides a telescopic floor stand, which comprises a base, wherein a fixed upright post is fixed at the top of the base, an extension upright post is embedded and installed at the top end of the fixed upright post, a high locking mechanism matched with the fixed upright post is arranged at the bottom end of the extension upright post, a sliding rail component is connected inside the extension upright post in a sliding way, a constant force scroll spring is installed in the sliding rail component, the stretching end of the constant force scroll spring is fixedly connected with the top end of the extension upright post, and a cross arm is installed on the sliding rail component. Preferably, a double-shaft torque hinge is installed at the end part of the cross arm, and an installation plate is fixed at the output end of the double-shaft torque hinge. Preferably, the base top is equipped with the mounting hole that is used for holding the fixed stand, the fixed stand is the cavity form, the connecting plate is installed to the bottom inboard of fixed stand, the base bottom is used for the shutoff board of shutoff mounting hole bottom through screw fixedly connected with, the shutoff board passes through screw and connecting plate fixed connection. Preferably, the lateral wall of fixed stand is equipped with a plurality of locking hole, high locking mechanism includes V type shell fragment and spacing post, the extension stand is cavity form, the bottom embedding of extension stand is fixed with the bottom end cap, the extension stand inboard is equipped with V type shell fragment, the department of buckling of V type shell fragment is fixed with spacing post, spacing post wears out extension stand lateral wall and locking hole cooperation, the both ends of V type shell fragment all contact with the inner wall of extension stand. Preferably, the sliding rail component comprises a U-shaped sheet metal part, a plurality of sliding blocks are fixed on two sides of the U-shaped sheet metal part, the sliding blocks are in sliding connection with the extension upright posts, a plurality of mounting seats are mounted on the inner sides of the U-shaped sheet metal part, circular arc grooves are formed in the mounting seats, the constant force scroll spring is mounted in the circular arc grooves, and one end of the cross arm is fixedly connected with the U-shaped sheet metal part. Preferably, the side wall of the extension upright post is provided with an avoidance slideway for avoiding the cross arm, and a baffle for shielding the avoidance slideway is fixed on one side of the U-shaped sheet metal part. Preferably, a decorative plate is arranged on the outer side of the cross arm. Preferably, universal wheels are arranged at four corners of the bottom of the base. Compared with the related art, the invention has the following beneficial effects: 1. Convenient and reliable height adjustment Through the high locking mechanism that V type shell fragment and spacing post are constituteed, a plurality of locking holes on the cooperation fixed column, the user only need press spacing post can easily adjust the extension height of extension stand, automatic locking after releasing, easy operation is swift, locks reliably. 2.
