The specific embodiment
With reference to the accompanying drawings the specific embodiment of the present utility model is made a detailed explanation below.
According to shown in Fig. 1 to Fig. 6, the collapsible underframe of a kind of infanette described in the present embodiment, include a Connection Block 1 and four folded tube 3 hinged with Connection Block respectively, folded tube 3 diagonal along a rectangle when deployed condition distributes, four folded tube ends are hinged with the connector of four vertex positions of baby bed bottom respectively, the cross bar of four sides of infanette is all also that two tubing that are hinged form, and when underframe is folding, whole infanette is thereupon folding like this.Described Connection Block includes two the first hinged seats 11 and two the second hinged seats 12, Connection Block center offers control hole 15 longitudinally, two described the first hinged seats are symmetrical arranged centered by control hole, and two described the second hinged seats are symmetrical arranged centered by control hole; Be mutually between acute angle and adjacent the first hinged seat and the second hinged seat side and be connected with reinforcing pipe 13; Described the first hinged seat, the second hinged seat are hinged by horizontally disposed bolt and folded tube respectively, and the end of bolt is threaded connection through sidewall and the reinforcing pipe of the first hinged seat, the second hinged seat.Described reinforcing pipe 13 not only plays the function of the seat that reinforces the connection, and is also beneficial to the connection of bolt simultaneously.The folded tube end hinged with described the first hinged seat also slidably connects keeper 4, described keeper includes to slide and is plugged in the slide contact part 41 of folded tube end, and one is connected to the location division 42 of slide contact part away from folded tube one end, the bore of location division is less than the bore of slide contact part; On described slide contact part, offer the chute 412 along folded tube length direction, chute is set on the bolt hinged with folded tube slidably, and between location division and bolt, is provided with the spring 40 in order to keeper is outwards ejected in keeper; The first described hinged seat inside upper part is provided with to prop up the location division of keeper and by the horizontal location portion 18 of folded tube horizontal location, the outside of horizontal location portion is inclined plane, and described end, location division is curved end 421; When underframe launches, the curved end of location division also finally snaps into horizontal location subordinate side along the inclined plane down sliding of horizontal location portion; The end of described slide contact part be provided with trumpet-shaped for bolt, snap in snap in mouthfuls 411, snap in and mouthful be communicated with chute.Described in arranging, snap in mouth 411, the narrowest place that snaps in mouth 411 is slightly less than the external diameter of bolt, and when assembling underframe, keeper in the end step assembles, and facilitates like this installation of folded tube.By will snap in mouthful aim at a bolt firmly press can time snap in mouthful the narrowest place of inner end and produce certain deformation and make bolt slip in chute and no longer deviate from.In described control hole, be provided with Control Component 2, Control Component includes control lever 21, push jack 22 and draw ring 23, described control lever is slidably arranged in control hole 15, described draw ring is fixedly connected on control lever upper end and extend out to control hole top, described push jack is fixedly connected on both sides, control lever middle part, the top of push jack is inclined-plane 221, and inclined-plane coordinates and offsets with the location division of keeper, and location division and horizontal location portion that push jack can promote keeper in the process of moving up depart from.The curved end 421 of described location division is sealing surface, and described both ends of the spring is against between curved end inwall and bolt.The curved end that sealing surface is set is convenient to the installation of spring, without using extra connector, improves efficiency of assembling.The first described hinged seat and the top of the second hinged seat outer end are provided with folded tube location division, folded tube location division includes the longitudinal register portion 16 in order to folded tube is positioned to vertical position, and in order to folded tube is positioned to the located lateral portion 17 of horizontal level, the surface that longitudinal register portion, located lateral portion coordinate with folded tube is arc-shaped surface.Described longitudinal register portion fitted bolt is positioned at folded state by folded tube, be beneficial to collapsible underframe folding after in stable state.Described located lateral portion fitted bolt, the positioning end of keeper and the horizontal location portion of Connection Block are positioned at deployed condition by folded tube, share the stressed of bolt link position and positioning end and horizontal location portion position, guarantee the whole service life of collapsible underframe.Be mutually between obtuse angle and adjacent described the first hinged seat and the second hinged seat side and be connected with stiffening piece 14.Stiffening piece makes Connection Block overall structure more firm, prevents the first hinged seat, the stressed excessive generation deformation of the second hinged seat outer end portion or damage.
When this collapsible underframe launches, the top that only need press Connection Block downwards, each folded tube is rotated relative to Connection Block, to the curved end of location division on keeper along the inclined plane of horizontal location portion, slide and final engaging to horizontal location subordinate side, two folded tube that are connected with two the first hinged seats are fixed, and whole underframe is in deployed condition.While packing up underframe, only need to pull Control Component by draw ring, the inclined-plane that makes push jack departs from horizontal location portion in the upper location division that outwards promotes keeper in moving past journey, can make folded tube upwards rotate and realize folding of underframe, and operation is very easy.This Undercarriage structure is simply compact, easy to assembly in addition, is beneficial to the lower production cost of control.
