Description
Technical field
The utility model relates to a kind of accessory of folding seat, refers in particular to a kind of folding seat leg by adjusting device.
Background technology
Existing folding seat and body contacting portion generally can be divided into lean against, seat portion and leg lean on, lean against, seat portion with leg by also can set level into a bed lain low simultaneously.Chair leg and back leg before the below of folding chair seat is provided with, be connected with adjusting device between front chair leg and leg lean on, the angle allowing user regulate leg to lean at any time, makes leg by reaching the angle of the most comfortable; The adjusting device that existing a lot of folding seat leg leans on is the expansion link that two blank pipes are nested together, and two blank pipe junctions are provided with spring catch, and its adjustment can only make leg lean on level or extreme lower position, and adjusting angle is too single; Existing leg also has multi-angle adjustable by adjusting device, but its complex structure, cost are high and regulate the shortcomings such as inconvenience.
Utility model content
Technical problem to be solved in the utility model is to provide a kind of leg easy to adjust, that structure is simple and durable and leans on adjusting device.
For solving the problem, a kind of folding seat leg described in the utility model is by adjusting device, comprise adjusting device body, described body is key-type, boring and larger opening, body interior is fixed with an iron plate, described iron plate is quadrangle, put and have latch on the upper surface of intrinsic side, opposite side has connecting hole, the longer side of iron plate has pawl, the crown of pawl is towards latch, described body has a U-type groove at it on the surface of larger, the upper surface of U-type groove has an oval elongated hole, the side surface of U-type groove is provided with a spring stack, on spring stack, cover has spring, in U-type groove, card has U-shaped button supporting with it, U-shaped button upper surface has bolt hole, oval elongated hole in bolt passing through bolt hole and U-type groove makes U-type groove and U-shaped button fix, described body has a fixing hole on the upper surface that it is less.
Compared with prior art, the utility model has the advantage of: easy to adjust, structure is simple and durable.
Accompanying drawing explanation
Below in conjunction with drawings and Examples, the utility model is described in further detail.
Fig. 1 is the structural representation of a kind of folding seat leg described in the utility model by adjusting device.
Fig. 2 is the part assembly drawing of Fig. 1.
Fig. 3 is the using state figure of a kind of folding seat leg described in the utility model by adjusting device.
As described in Fig. 1 to Fig. 3,1, body; 2, iron plate; 3, latch; 4, connecting hole; 5, pawl; 6, U-type groove; 7, oval elongated hole; 8, spring stack; 9, spring; 10, U-shaped button; 11, bolt hole; 12, bolt; 13, fixing hole; 14, front chair takes off; 15, leg leans on.
Detailed description of the invention
As shown in Figure 1 to Figure 3, a kind of folding seat leg described in the utility model is by adjusting device, described device is by body 1, play to connect and form with the iron plate 2 of fixation and U-shaped button 10, body 1 is in key-type, boring and larger opening, iron plate 2 one is put and is taken off 14 with front chair be connected interior one of body 1, the upper surface put in body 1 has latch 3, take off 14 sides be connected with front chair and have connecting hole 4, the longer side of iron plate 2 has pawl 5, the crown of pawl 5 is towards latch 3, body 1 has a U-type groove 6 at it on the surface of larger, the upper surface of U-type groove 6 has an oval elongated hole 7, the side surface of U-type groove 6 is provided with a spring stack 8, on spring stack 8, cover has spring 9, again U-shaped button 10 is stuck in U-type groove 6, through the bolt hole 11 on U-shaped button 10 and the oval elongated hole 7 in U-type groove 6, U-type groove 6 is fixed by bolt 12 with U-shaped button 10, body 1 opposite side has fixing hole 13 and is connected by 15 with leg.
Further illustrate, when we upwards regulate leg to lean on 15, can directly with pin leg by 15 picture on carry, pawl 5 on iron plate 2 can skip bolt 12, adjustment is decontroled after putting in place, pawl 5 is just stuck on bolt 12 and prevents it from retracting, when we need the leg of retracting upwards by 15 time, only need press U-shaped button 10, button will drive bolt 12, owing to U-type groove 6 having oval elongated hole 7, make bolt 12 can away from the latch 3 on iron plate 2, at this moment just leg can be retracted by 15, at relieving button after retraction, bolt 12 card be got back in pawl 5 and locks.
Further illustrate, Fig. 1 is example, and iron plate 2 when mounted pawl 5 must in the below of bolt 12.
Above-described embodiment is only be described preferred embodiment of the present utility model; not scope of the present utility model is limited; under the prerequisite not departing from the utility model design spirit; the various distortion that those of ordinary skill in the art make the technical solution of the utility model and improvement, all should fall in protection domain that claims of the present utility model determine.
