Abstract

Support frame of travelling bed. At least post columns and side columns are connected to each other by connectors to form the frame body. Both the top end and the bottom end of each post column are fixed to corresponding connector respectively. Side columns are articulated each other, both the top end and the bottom end of each side column are articulated corresponding connector respectively. A distance rod is also provided between the two side columns on the right side or the left side of one end of the frame body, in which: the bottom end of the distance rod is pivoted on a sliding sleeve directly, a side column goes across a hole therein. A locking and positioning device is provided on the sliding sleeve to position it onto a side column. The middle part of the distance rod is pivoted with one end of a limiting bar, and the other end of the limiting bar is pivoted with another side column.

Description

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to the technical field of a support frame, particularly to a support frame structure of a folding bed. BACKGROUND OF THE INVENTION In the prior art, a support structure of a folding bed is as shown in FIG. 1 , and at least a column body 侧 and a side bar 2 ′ are pivotally connected by a pivot seat 3 ′ to form a frame body, and the upper and lower sides of each 4 column Γ The ends are respectively fixed on the upper and lower corresponding pivot seats 3, and the side bars 2 are pivotally connected together. The upper and lower ends of each side bar 2 are respectively pivotally connected to the upper and lower pivot seats 3 corresponding to the crossover. , above, laying a mat on the top surface of the frame, that is, forming a folding bed.

In order to make one end of the mat can be supported, it is convenient for the user to rely on the back, and a strut 4 is further disposed between the two side bars 2' on the left and right sides of the end of the frame body, and the lower end of the strut 4 Pivoted on one side bar 2, upper, middle section is inserted in one sleeve hole of double sliding sleeve 5, and the other side rod 2' is inserted in another sleeve hole of double sliding sleeve 5', the double sliding sleeve The 5' has a locking positioning device (this is a common structure, not shown) by which the double sliding sleeve 5' can be positioned on the strut 4 and the other side bar 2'. In order to prevent the wrinkles from being erected after the mat is erected, a telescopic inner tube 6 is placed over the struts 4, and when the struts 4 are erected, the inner tube 6 can be pulled out to extend the support height. , make the mat more flat after being propped up.

In this way, the locking positioning of the double sliding sleeve 5 by the locking and positioning device is released, the strut 4' is pressed down or propped up, the double sliding sleeve 5 is driven, and the struts 4 and the side bars 2 are slid. Press the strut 4 to the side of the side bar 2, so that the mat can be placed flat on the top surface of the frame, or the brace 4 can be held in place, and the double sliding sleeve can be made again by the locking positioning device. 5' is positioned on the strut 4, and the other side bar 2, so that the support of the brace 4' is positioned in an appropriate position, so that the mat can be propped up, which is convenient for the user to rely on.

However, the support frame of this structure is that the lower end of the brace 4' is pivotally connected to a side bar 2, and the brace 4 is inserted into the sleeve hole of the sliding sleeve, and is limited by the sleeve hole, in order to make The strut 4 can be erected or pressed, and the double sliding sleeve 5 must be used. Moreover, in order to have a sufficient supporting height, the struts 4 must also be covered with the inner tube 6, so that the structure is complicated. The cost is also higher. SUMMARY OF THE INVENTION It is an object of the present invention to provide a support frame that is structurally simple and low in cost. In order to achieve the above object, the solution of the present invention is:

A support frame, at least a column and a side bar are pivotally connected to form a frame body, and the upper and lower ends of each column are respectively fixed on the upper and lower corresponding pivot seats, and the side bars are pivotally connected together. The upper and lower ends of the side bar are respectively pivotally connected to the upper and lower pivot seats corresponding to the cross, and a strut is further disposed between the two side bars on the left and right sides of one end of the frame body, wherein the support The lower end of the rod is directly pivotally connected to a single sliding sleeve, and one side rod is inserted into the sleeve hole of the single sliding sleeve, and the single sliding sleeve has a locking positioning device capable of positioning the same on the side rod, the supporting rod The middle section is pivotally connected to one end of a limiting rod, and the other end of the limiting rod is pivotally connected to the other side pole.

After adopting the above structure, when the invention is used, the lock positioning position of the locking and positioning device is released, and the brace is pressed or propped up, and the single sliding sleeve is driven to slide on the side bar, so that the brace can be pressed to Adjacent to the side bar, the mat placed on the frame can be placed flat on the top surface of the frame, or the brace can be held in place, and the single sliding sleeve can be positioned on the side bar again by the locking positioning device. And with the limit action of the limit rod, the support of the strut is positioned in an appropriate position, so that the mat laid on the frame body can be propped up, which is convenient for the user to rely on.

The invention has the lower end of the strut directly pivoted on the single sliding sleeve and is limited by the limiting rod, and in order to have sufficient supporting height, the single sliding sleeve can be slid upward as much as possible without additional addition. The inner tube, therefore, has a significantly simpler structure and lower cost than the prior art double sliding sleeve and inner tube. BRIEF DESCRIPTION OF THE DRAWINGS FIG. 1 is a schematic structural view of a prior art;

Figure 2 is a schematic view of the structure of the present invention. DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS As shown in Fig. 2, the present invention discloses a support frame, at least the column 1 and the side bars 2 are pivotally connected to each other through the pivoting seat 3, and a mat is laid on the top surface of the frame body, thereby forming a folding bed.

The upper and lower ends of each of the columns 1 are respectively fixed to the upper and lower corresponding pivot seats 3. The side bars 2 are pivotally connected at their midpoints by means of pivots (not labeled), and the upper and lower ends of the rods 2 are pivotally connected to the upper and lower pivoting seats 3 respectively.

A strut 4 is further disposed between the two side bars 1 on the left and right sides of one end of the frame body, and the lower end of the strut 4 is directly pivotally connected to a single sliding sleeve 5, and a side bar 1 is inserted in the single In the sleeve hole of the sliding sleeve 5, the single sliding sleeve 5 has a locking positioning device 51 (which is a common structure, not specifically shown) which can position the single sliding sleeve 5 itself on the side rod 2, which is The middle section of 4 is pivotally connected to one end of a limiting rod 6, and the other end of the limiting rod 6 is pivotally connected to the other In use, the locking and positioning device 51 is opened, and the locking positioning of the single sliding sleeve 5 is released, and the strut 4 can be propped up, and the single sliding sleeve 5 is driven to slide on the side bar 2 until the proper position, and the locking positioning is performed. The device 51 again positions the single sliding sleeve 5 on the side bar 2, and by means of the limiting action of the limiting rod 6, the support of the strut 4 is positioned in an appropriate position, so that the mat laid on the frame body can be propped up. It is convenient for the user to rely on.
