The specific embodiment

In order further to explain the technical scheme of the utility model, come the utility model is set forth in detail through specific embodiment below.

Like Fig. 1 and cooperate Fig. 2 to shown in Figure 9, the utility model has disclosed a kind of be used to connect all right one way or the other doubling and extensible rod member folding structure, and it comprises first connector 1, second connector 2 and self-locking mechanism 3.

The rear portion of first connector 1 and second connector 2 is individually fixed on the termination to pole A; And each connector front portion reaches forward and has extended upward two auricles 11; 21, wherein second connector 2 two auricles 21 be to be located between two auricles 11 of first connector 1.

Wherein, first connector, 1 front portion reaches forward and has extended upward two auricles 11, and the last front end of auricle 11 is an arc; Nearly middle and upper part is provided with pivot hole 12; Form short slot 13 below the pivot hole, the short slot 13 in pivot hole 12 is positioned on the same vertical horizontal line, and promptly short slot 13 is to be positioned on the extended line in 12 centers of circle, pivot hole; Support surface 14 is formed at the bottom of auricle 11, is launched into 180 degree to make two connectors.

Second connector, 2 structures and first connector 1 are similar, and the last front end of auricle 21 is an arc, and nearly middle and upper part is provided with pivot hole 22, form short slot 23 below the pivot hole, and pivot hole 22 is positioned on the same vertical horizontal line with short slot 23, and support surface 24 is also formed at the bottom of auricle 21.Second connector 2 two auricles 21 be to be located between two auricles 11 of first connector 1, two connectors are connected after being arranged in pivot hole 12 and pivot hole 22 through a pivot 4.

First connector 1 is after second connector 2 is sheathed on, and the center also is provided with a self-locking mechanism 3, the back-moving spring 33 that lock pin 32 that this self-locking mechanism 3 comprises slide block 31, driven by slide block and pulling slide block reset.Wherein, slide block 31 is formed with an inner chamber, and back-moving spring 33 is positioned at the inner chamber of slide block; And be formed with elongate slots 34, two connectors on two lateral walls of slide block when sheathed, and its pivot 4 also is arranged in the elongate slots 31 of slide block, thus self-locking mechanism 3 also is hubbed between two joints; The bottom of slide block also is provided with a capping 35, and the pivot that back-moving spring 33 is resisted against in the slide block wears between place and the bottom; Lock pin 32 is to be arranged in the set pivot hole 321 of slip front, its mobilizable first connector 1 and second connector, 2 mutual the expansion in the overlapping short slot of each auricle of back, i.e. short slot 13, short slots 23 of first connector and each auricle bottom of second connector of being placed in.

When launching, it is formed when supporting, referring to figs. 1 to shown in Figure 4 with folding structure; Just the two couples of pole A are expanded to parallelly, and first connector 1 is connected with second connector 2, and the lock pin 32 that is arranged in the middle part is placed in first connector 1 and launches the overlapping

short slots

13,23 of each auricle afterwards each other with second connector 2; At this moment; In the self-locking mechanism 3, the front end of slide block 31 is fixed in the overlapping short slot, and pivot 4 is located in the middle and lower part of elongate slots 34; Make back-moving spring 33 rely on pivot 4, in the inner chamber of slide block 31, be tensioned state.Reached self-locking state thereby make between two connectors, also played certain supporting role for this junction.

In the time will folding structure being packed up, with reference to figure 5 to Fig. 7, during two couples of pole A of folding; Push slide block 31, make lock pin break away from the holding effect of two overlapping short slots, two connectors break away from connection status; At this moment, the lock pin 32 that is positioned at slide block 31 tops breaks away from the overlapping short slot of two auricles, is positioned on one of them short slot; When two connectors are movable relatively, because auricle is that to go up front end be arc, lock pin 32 can slide along auricle (like Fig. 7).The activity of lock pin 32 also drives two auricles; And then having driven pivot 4 activities, the position of pivot 4 in the elongate slots 34 of slide block 31 moves up (like Fig. 5), at this moment; Back-moving spring 33 is changed towards lax normality by original tight state gradually; The locking state of slide block 31 weakens gradually, and the annexation between two connectors reduces, two pairs of progressively doublings of pole A.

When two couples of pole A are full folding state, extremely shown in Figure 10 like Fig. 8, at this moment, and the intersection doubling gradually of two connectors, the upwards movable top to elongate slots 34 of pivot 4 is 33 pairs of connectors of back-moving spring not locking effect of relaxed state.

The folding structure of the utility model is provided with a self-locking mechanism and makes and realize self-locking between the connector through between two connectors, connecting, can make connect upon deployment between the folding parts firm, also convenient and swift during folding.Like Figure 11, Figure 12, shown in Figure 13, the utility model can be used for folding table leg, folding desktop, foldable rod member such as folding bed or folding position, middle part, it is simple in structure, and firm supporting is applied widely.

Product form of the foregoing description and graphic and non-limiting the utility model and style, the those of ordinary skill of any affiliated technical field all should be regarded as not breaking away from the patent category of the utility model to its suitable variation or modification of doing.
