Description

The table pin

The utility model relates to a kind of pin, refer to a kind of be articulated in especially at the bottom of, with a table pin upright position, and form the table body support frame in two jiaos of spaces, make a pin that can support by body frame and pole of the table pin that is articulated in desktop under.

At present, public foldable table body movable, collection is the square vertical rotatable support of locating to articulate with the table pin under table, and this desk defective is more; Support shrinks for a long time, diastole is used, and easily causes deformation of timbering or damage, and support is short service life, and maintenance cost is acted and bothered expense high; As give it up, cause waste again.Articulate poor, the easy generation of table body support force that constitutes support by two rectangle lamellar bodies in addition and shamble, use dangerous.

The purpose of this utility model is that a kind of improved table pin will be provided, and it not only supports firmly, and long service life.

The purpose of this utility model is achieved in that a pin is by female bar, pays bar, body frame, pole and bluff piece and forms: holding section, side holding section and following holding section are arranged on female bar; Paying the bar end has and last snap-latch piece, side snap-latch piece and following snap-latch piece with respect to each holding section on female bar; Last snap-latch piece up turns down a length in vertical direction with the shaft of paying bar, and the side holding section that the side snap-latch piece is relative with it with following snap-latch piece, following holding section become tight fit; Body frame is the U-shaped lamellar body that is the groove shape, and one end both sides parallel plate respectively has a circular hole, and at the bottom of being articulated in, this end oppositely has the relative flanges of number along the parallel plate inboard, both sides that extends nearly central position; Pole is the pole of a rectangle, and the one end is coupling at the nearly middle position of body frame, and locatees, is fastened on several opposing flanges of two parallel plate inboards; The other end has perforate, is articulated in a pin; Bluff piece is flexual bluff piece, is located at the body frame outside and the pole place that is coupling; Bluff piece has clasp, is fastened on the relative button of another outside parallel plate of body frame.The following of female bar can stretch into an engaging screw, and the engaging screw is fastened on down in the fixing hole on the snap-latch piece.There is the side groove both sides, pole one place, and the inboard one group of flange of two parallel plates location wherein.The both sides at another place of pole are the plane, and inboard another group flange blocking of two parallel plates is on it.

Because adopt such scheme, the utility model structure is firm, and is safe in utilization; The table pin can bear the pressure of any direction; Long service life; Be easy to the collection carrying, do not take up space.

Below by accompanying drawing and embodiment the utility model is further described.

Among the figure: 1 female bar, 2 pairs of bars, 3 engaging screws, 4 foot supports, 5 body frames, 6 poles, 7 bluff pieces, 8 desktops, at the bottom of 9, on 11 the holding section, 12 times holding sections, 13,14 side holding sections, snap-latch piece on 21,22 times snap-latch pieces, 221 fixing holes, 23,24 side snap-latch pieces, 51,52 parallel plates, 53 circular holes, 54 flanges, 55 places that are coupling, 61 perforates, 62 side grooves, 71,72 buttons.

Referring to Fig. 2,3; The utility model embodiment mainly is made of female bar 1, a pair bar 2, on the shaft of female bar 1, establish on one holding section 11, one group of

side holding section

13,14, holding section 12 once, there are snap-latch piece 21 on, side snap-

latch piece

23,24, following snap-latch piece 22 in female relatively bar 1 each the set place, holding section that pays the end of bar 2, last snap-latch piece 21 up turns down a suitable length in vertical direction with the shaft of paying bar 2, and side snap-

latch piece

23,24,22 shafts with pair bar 2 of following snap-latch piece extend a suitable length in horizontal direction forward.

Shown in Fig. 4,5; After each snap-latch piece of paying bar 2 stretched into each holding section on relative female bar 1, last snap-latch piece 21 can resist female bar 1 inwall at the upper limb of

last holding section

11,22 side holding sections relative 13,14 of side snap-

latch piece

23,24 and following snap-latch piece, 12 one-tenth one tight fits in following holding section with it, stretch into an engaging screw 3 by the below of female bar 1 again, after being fastened on down engaging screw 3 in the fixing hole set on the snap-latch piece 22 221, to engage screw 3 and lock, pole 2 and female bar 1 are combined closely.

As shown in Figure 6; Table foot support 4 comprises a body frame 5, a pole 6 and a bluff piece 7; Body frame 5 is integrated punchings, the U-shaped lamellar body that is the groove shape, its both sides

parallel plate

51,52 ends respectively are provided with a circular hole 563, at the bottom of can being articulated in 9, at the bottom of making 9, the female bar 1 of table pin forms triangular spaces with table foot support 4, and an end is oppositely along stretching inboard, the nearly central appropriate location pole 6 that is coupling, and there are several relative flanges 54 55 both sides parallel plates, 51,52 inboards, the paraxial place of connecing.

As shown in Figure 6A; Number flange 54 can be located, blocking is executed in the pole 6 of body frame 4 inboards, that is, wherein one group of flange 54 just can make the side groove 62 of pole 6 both sides be fastened on the flange 54 of two parallel plates, 51,52 inboards with pole 6 relative engagings place, uses as the location; And the opposite position of another group flange 54 blocking poles 12, the both sides of pole 6 are plane, make pole 6 exempt to rock in two

parallel plates

51,52; Wherein a side parallel plate 51 is established a pliability bluff piece 7, and bluff piece 7 has a clasp 71, can be fastened on the button 72 of body frame 5 opposite side parallel plates 52 relative positions, with body frame 5 and the firm reinforcement of pole 6 overlappings; Be coupling the pole 6 of body frame 5 one ends, its other end also has a perforate 61, and perforate 61 is articulated in a pin appropriate location, can amount to the contraction of movable table body, diastole, firm reinforcement by table foot support 4.

As shown in Figure 7; At the bottom of table foot support 4 is articulated in a table pin, when the body frame 5 and pole 6 places of being coupling 55 of table foot support 4 strut formation one straight line, fasten body frames 5 and pole 6 overlappings with a pliability bluff piece 7 again, the female bar 1 of table pin at the bottom of being articulated in can be supported by body frame 11 and pole 6.

As shown in Figure 8; When the female bar 1 of table pin is amounted to, is contracted under the table side, only need the clasp 71 of bluff piece 7 is opened with button 72, by the application of force in the female bar of table pin 1 lateral, its inner edge at the bottom of table is amounted to again, make original shape body frame 5 in line change into doubled state with pole 6.
