Abstract

The utility model discloses a pull mode bar folding device, which comprises a first folded sleeve barrel and a second folded sleeve barrel, which are mutually hinged and are on the same shaft, wherein the rear end of the second folded sleeve barrel is coaxially provided with a pull sleeve barrel, a mandrel is sleeved in the second folded sleeve barrel and the pull sleeve barrel, the center portion of the mandrel is provided with a chute, and a first pin shaft is penetrated between the mandrel and the second folded sleeve barrel, a spring is mounted in the chute, a second pin shaft is penetrated between the rear end portion of the mandrel and the push sleeve barrel, the front end portion of the mandrel extends in the first folded sleeve barrel. The pull mode bar folding device can conveniently achieve fast folding, deploying and position of the bar fitting, scattered fittings can not appear during folding, disassembling and assembling tools are not needed to be further carried, and storage and carrying of folding furniture are led to be more convenient and faster.

Description

A kind of pulling type rod folding device

Technical field

The utility model relates to a kind of connection set that is used between two rod members, especially a kind of can realize two rod members open folding device with folding fast.

Background technique

A lot of Family Day staple such as Baby crib, tent or table, chair etc., be usually designed to folding form, this is very important for limited home room, simultaneously, for some article that need carry or carry, folding also can playing collected the purpose little and easy to carry that takes up room.But existing folding guest bed or removable furniture, often wait between its two sections rod members and connect and fastening by some adapter sleeves or screw-nut, the scattered problem of being inconvenient to take in of accessory that disassembles with regard to existence like this, and also need extraordinarily tool using to assist dismounting sometimes, waste time and energy, make troubles to the user.

Summary of the invention

For addressing the above problem, the utility model provides a kind of pulling type rod folding device that need not to carry in addition instrument or accessory and can realize quick folding.

The technological scheme that its technical problem that solves the utility model adopts is:

A kind of pulling type rod folding device, comprise and being hinged and coaxial first folded sleeve and second folded sleeve, the described second folded sleeve rear end is coaxially arranged with the pulling sleeve, be set with axle in described second folded sleeve and the pulling sleeve, described axle middle part be provided with chute and and second folded sleeve between cross-under first bearing pin is arranged, in the described chute spring is housed; Cross-under has second bearing pin between described mandrels backend portion and the pulling sleeve, and described axle front end probes in first folded sleeve.

As further improvement of the utility model, the part that described axle front end probes in first folded sleeve is the inclined-plane, and the true dip direction on inclined-plane is towards the hinged side of described first, second folded sleeve.

The beneficial effects of the utility model: can realize the quick folding of rod member and launch the location by this rod folding device, in the folding process scattered accessory can not appear, also need not to carry dismantling device in addition, make the collection of Folding furniture and carry all more convenient.

Description of drawings

The utility model is described in further detail below in conjunction with accompanying drawing.

Fig. 1 is the user mode figure behind the utility model suit rod member;

Fig. 2 is the structure broken away view of Fig. 1;

Fig. 3 is the partial sectional view of rod member in the folding process;

Fig. 4 is the folded state diagram of rod member.

Embodiment

With reference to Fig. 1, Fig. 2, a kind of pulling type rod folding device, comprise and being hinged and coaxial first folded sleeve 1 and second folded sleeve 2, second folded sleeve, 2 rear ends are coaxially arranged with pulling sleeve 3, be set with axle 4 in second folded sleeve 2 and the pulling sleeve 3, axle 4 middle parts be provided with chute 8 and and second folded sleeve 2 between cross-under first bearing pin 5 is arranged, spring 7 is housed in the chute 8; Cross-under has second bearing pin 6 between axle 4 rearward end and the pulling sleeve 3, and the axle front end probes in first folded sleeve 1.

When this device is used for the rod member connection, two rod members are set in the two ends of folding device, adopting bearing pin to connect in the present embodiment is sleeved on rod member on the folding device, wherein, on the rod member of pulling sleeve 3 sides pin-and-hole and chute need be set, make first bearing pin 5 pass pin-and-hole during suit, and make second bearing pin 6 pass chute.

With reference to Fig. 3, Fig. 4, when rod member needs folding, to spur sleeve 3 spurs laterally, axle 4 moves under pulling sleeve 3 drives laterally, and spring 7 is compressed, move to disengaging first folded sleeve 1 of its front end when axle after, unclamp pulling sleeve 3, axle 4 resets under spring 7 effects, at this moment, just two rod members can be folded up relatively.

In the present embodiment, the part that axle 4 front ends are probeed in first folded sleeve 1 is made into inclined-plane 41, and the true dip direction on inclined-plane is towards the hinged side of first, second folded sleeve, like this, when rod member need launch again, axle just can realize flexible automatically resetting along the inclined-plane.

For ease of user's operation, can hand-held position 9 be set on pulling sleeve 3 surfaces.

The utility model structural design is ingenious, can realize the quick folding of rod member easily and launch the location, scattered accessory can not occur in the folding process, also need not to carry in addition dismantling device, makes the collection of Folding furniture and carries all more convenient.
