CN2276289Y - Connecting block structure for collapsible cot - Google Patents

Abstract

The utility model discloses a connecting block structure for a collapsible cot. A transverse supporting rod on the bottom of the cot is sheathed with the connecting block, and the angle of the connecting block can be rotated; the connecting block is pivoted with a cross supporting frame, wherein, the connecting block is provided with a sleeve which is sheathed and connected to the transverse supporting rod to do a limited rotation, and one side end of the sleeve extends to form an inclined pivot base which is connected with the cross supporting frame. When the transverse supporting rod is bent, the cross supporting frame is driven by the connecting block which does the self rotation; in this way, the cross supporting frame is folded and collected smoothly.

Description

The linking block structure of folding infanette

The utility model relates to a kind of linking block structure of folding infanette.You Zhiyi applies to the interface components that infanette two bottom sides pole is set up central cross frame, makes cross can fold or launch the location with the stretching drive of the bending of both sides pole in the lump.

The folding infanette of commonly using, as shown in Figure 6, main connect four bent joint connecting rod B in top, and the bottom articulates a strut C by vertical struts A end and extends and be connected a cross Connection Block D to central authorities, constitutes cross supporter frame by four vertical struts A; During its folding, promptly shown in Fig. 7,8, when four vertical struts A are closed up to central authorities, the joint connecting rod B on its top promptly bends downwards with the pass climate and other natural phenomena of a season body of rod of middle section, and the cross strut C of bottom then makes it upwards to fold to push away by its pivot end and is with Connection Block D to rise.

Yet, in the above-mentioned structure of commonly using product, the cross strut C that is limited to the bottom is that direct pivot is connected on the Connection Block D of four vertical struts A and central authorities, and its pivot end also can't be made axial pivot, therefore bending can produce the state that pins down each other among a small circle when folding, and makes it fold non-energy smooth operation; And this kind situation is even more serious when the length and width ratio gap of infanette is big, so the general only infanette of the cross bottom bracket of tool is designed to square more.

The purpose of this utility model promptly is to provide a kind of linking block structure of folding infanette, make infanette fold the operation smooth and easy.

For achieving the above object, the utility model infanette two bottom sides pole is connected piece by it and connects a cross frame, this cross frame and both sides pole utilize be connected piece can be relative to doing rotating of three-dimensional space angle changing, infanette is folded operate smooth and easy.Wherein, this linking piece has the sleeve pipe of a noose on bottom transverse pole, and can do the rotation of limited angle, and these sleeve pipe one side elongation moulding two oblique parallel-plate bodies form a pivot seat, be articulated with the suitable end for cross frame of this pivot seat, the central authorities in bottom transverse pole establish a joint that can upwards bend in addition; Owing to can the cross that be connected the connection of piece pivot seat be folded support by its central cross Connection Block through being connected piece drive cross frame and rotating self appropriate cooperation when lateral strut upwards bends.

After adopting said structure, the utility model because be connected cross frame that piece connects and joint portion that lateral strut is constituted can be in the three-dimensional space angle changing, overcome pining down when lateral strut is relative with cross frame to bend, infanette is folded operate smooth and easy.

The utility model is described in further detail below in conjunction with graphic and embodiment.

At first consult shown in Figure 1ly, the utility model is connected piece 1 and is located at infanette two bottom sides lateral strut 2 and central cross frame 3 junctions, folds smoothly by lateral strut 2 interlock cross frames 3 when infanette integral body is folded.Wherein, be connected piece 1, shown in Fig. 2,3, has a sleeve pipe 11, in order to noose on lateral strut 2, the suitable distance of being separated by on its body one side pipe wall is provided with two radially long slot bores 111, the side pipe wall in addition of long slot bore 111 correspondences is set as a circular hole 112, the long slot bore 111 that places sleeve pipe 11 by two rivets 13 is preset in the circular holes 21 with lateral strut 2, make the cap portion 131 of rivet 13 be arranged in long slot bore 111, by other mother rib lateral rotundum 112 the nail body end riveting that rivet 13 stretches outside lateral strut 2 is put down in the circular hole 21 of lateral strut 2 again; In addition, sleeve pipe 11 is with respect to the vertical diameter moulding laterally one pivot seat 12 of long slot bore 111 tool rivets 13, and its pivot seat 12 has two parallel relative plate bodys, and suitable two correspondences of establishing bore a hole 121 on the plate body, wear wherein for cross frame 3 rod ends, and wear knot with a rivet 14.

When whole infanette by deployed condition (as Fig. 4, when 5) desiring to fold, the top bottom horizontal pole 4 of infanette, 2 can be respectively by central joint 41,21 bendings in opposite directions, four vertical struts 5 are drawn in to central authorities, simultaneously the bottom cross frame 3 of central authorities can make the bending of upwards arching upward of its four supports by the cross joint seat 31 at center, and its support is when folding, because of producing the state of a non-unidirectional relative bending with lateral strut 2, cause the start that pins down bending mutually, the utility model utilization is connected the sleeve pipe 11 of piece 1 with the rotation of its long slot bore 111 along lateral strut 2 and quilting rivet 13 works one limited angle, and cross frame 3 forms relative swinging with the pivot seat 12 that is connected piece 1 simultaneously, suitable make be connected piece 1 connect joint portion that cross frame 3 and lateral strut 2 constituted can be at the three-dimensional space angle changing, lateral strut 2 and cross frame 3 are relative to bend the action that pins down that is produced thereby overcome.

Claims (1)

1, a kind of linking block structure of folding infanette, it is characterized in that: this linking piece has the sleeve pipe of a noose on lateral strut, and on sleeve pipe, establish two so that rivet is worn the radially long slot bore of knot lateral strut, and the oblique pivot seat of jacket exterior one side elongation moulding one pivot knot cross frame, the pivot seat has two parallel plate bodys.
