Description

Foot frame fastening and insertion structure of combination frame

The footrest fastening and insertion structure of the creative combination frame is mainly applied to the technology of quickly and firmly fastening the foot base to the bottom of the combination frame by using the fastening body and the insertion groove.

According to the traditional conventional combination frame, the utility model comprises: front, rear, left and right four support rods, wherein the support rod is provided with a plurality of horizontal connecting plates on the upper and lower sides, and the support rods are arranged in an equidistant arrangement from top to bottom. a hooking hole, the horizontal connecting plate is provided with a hooking portion corresponding to the hooking hole of the supporting rod, thereby being hooked in the hooking hole of the supporting rod, and the screw and the nut are used at the four corners of the bottom of the combined frame The locking method is provided with four pulleys or four supporting feet.

However, in the above-mentioned conventionally used combination frame, when actually assembling the pulley or the supporting leg, it is necessary to use a screw and a nut to lock the fixed pulley or the supporting leg at the position of the four corners of the bottom of the combination frame, which not only increases the manufacturing cost, but also increases the manufacturing cost. At the same time, it will also lead to many troubles and inconveniences in assembly. It will make users feel that it is a time-consuming and labor-intensive product, and it is one of the problems and defects that have yet to be solved.

In addition, the conventionally used combination frame, when actually assembling the pulley or the supporting leg, only uses the screw and the nut to fix the pulley or the supporting leg to the bottom of the combined frame, only the radial fixing, the lack of the axial direction. Completely balanced to allow the pulley or support of the frame When the foot slides or moves, the transmission of the original force is an eccentric load, which is more likely to cause a wobble shift phenomenon, resulting in instability of the pulley or support leg of the combination frame; moreover, due to the improper speed, the overall load of the combination frame causes gravitational acceleration, resulting in Pulleys or support feet have insufficient support and are skewed or broken, which is the second problem that remains to be solved.

The creator is currently engaged in the manufacture and design of related products, accumulated many years of practical experience and experience, and has actively invested in the spirit of innovation and improvement in response to the existing problems and lack of traditional custom combination frames. And the insertion structure.

The technical means applied by the new problem solving and the effect of the prior art are as follows: the bottom of the foot is provided with a pulley or a supporting leg, and the two outer sides of the foot are provided with two fastening bodies, the fastening The outer end of the body is provided with a blocking portion, and the fastening body is provided with an embedded groove corresponding to the foot. The embedded groove is provided with a connecting portion having an outer diameter smaller than the blocking portion, and the bottom portion of the supporting portion corresponds to two buckles. At the periphery of the body, there is a positioning wall which is arranged in an L shape and extends upwards. The positioning wall is provided with an insertion groove, so that when the foot is combined with the angle steel, the groove can be fixed to the angle steel by using the embedded groove. In addition to the inner wall and the outer wall, the bottom of the angle steel can also be embedded in the insertion groove inside the positioning wall to form a fast and firm and firm fixed relationship, which can save cost, save time and labor, and can be improved. User's good feeling, with the front and rear (X-axis), left and right (Y-axis) and up-and-down (Z-axis) three-axis clamping, so that the pulley or support foot of the foot is more stable when sliding or moving, can increase The overall load capacity of the combination frame There is an improvement in efficacy, reaching for its main purpose.
