Description

The hinge assembly

Technical field

The utility model relates to a kind of floor spring, and the heavier gate that described floor spring support is formed with whole glass in order to regulate switching, is embedded in underground usually during use.

Background technology

Floor spring roughly all is to be embedded in underground to use, by the sleeve pipe of built-in floor spring assembly with in fact support the gate and regulate the floor spring assembly of rotating open-close and cover the sleeve pipe upper end and form with the lid that finishes installation.

Fig. 1 shows the drawing of spring assembly traditionally.As shown in Figure 1, floor spring assembly body 1 extends to length direction, is provided with the support gate at a side front end, the hinge 2 of control rotation.Fig. 2 shows the drawing of camshaft structure shape.As shown in Figure 2, hinge cam axle construction body by be provided with the revolving force that bears big reveal and pass on to door direction the power that is used to regulate the gate rotation leading section 20a hinge axis of rotation 20 and form with it one, a cam 30 that is combined on the hinge forms.So hinge 20 becomes camshaft simultaneously.If therefore hinge rotates according to the switching at gate, cam is and then rotation simultaneously also.

Fig. 3 a and Fig. 3 b show the drawing of the hinge cam axle construction body user mode that is installed in the hinge assembly.If hinge 20 rotates according to the switching at gate, will drive integraty and be bonded to cam 30 on the hinge, to regulate the switching at gate.

As shown in Figure 2, existing hinge camshaft structure body forms integraty as parts, forms cam separately.

The utility model content

The technical problems to be solved in the utility model is to provide a kind of hinge cam axle construction body, this hinge cam axle construction body uses the cam of the dual structure of being made up of overhead cam and following cam and is assembled together Contraband font upper plate with it, simplify the assembling parts program, make the assembling of hinge cam axle construction body become simpler, manufacturing is more prone to, and saves cost of manufacture.

Meanwhile, by strengthening the size of overhead cam, reduce the size of cam down, the radius of gyration of cam is diminished, and it is big that the radius of gyration of overhead cam becomes, in the pent process in gate, effect by overhead cam reduces angular velocity of rotation, to play the effect that slows down big closing speed, use undersized cam in the lower end, to use bigger space.

For solving the problems of the technologies described above, the utility model adopts following technical scheme: the utility model is to be combined in the lower end, gate by hinge, above-mentioned hinge rotated simultaneously when the gate was opened, make above-mentioned hinge return to previous status by the recuperability that acts on above-mentioned hinge, in the hinge assembly with the floor spring of closing the gate, overhead cam and following cam are combined on the hinge, keep certain intervals each other, above-mentioned cam size down is less than above-mentioned overhead cam, first jack and second jack of side formation in the square shape lower plate in order to insert first roller and second roller, opposite side in above-mentioned square shape lower plate forms the 3rd jack, one side of Contraband font upper plate forms the 4th jack and the 5th jack corresponding to first jack and second jack, above-mentioned square shape lower plate and above-mentioned Contraband font upper plate are combined on the support separately, following cam is placed on the above-mentioned square shape lower plate, sandwiching Contraband font upper plate between cam and the overhead cam down, first roller is inserted in first jack and the 4th jack, second roller is inserted in second jack and the 5th jack, the side that roller inserts rod is inserted in above-mentioned the 3rd jack, and the 3rd roller is inserted in that above-mentioned rollers is inserted rod and the invention of the floor spring hinge assembly that combines.

Compared with prior art, the utlity model has following advantage: the cam and the assembled Contraband font upper plate that is incorporated into this of the dual structure that the utility model utilization is made up of overhead cam and following cam, simplify the component-assembled program, assembling and making hinge cam axle construction body, making is become be more prone to, can save cost of manufacture again.Descend the little structure of cam greatly by overhead cam simultaneously, the radius of gyration of cam is diminished, it is big that the radius of gyration of overhead cam becomes, thereby in closing the process at gate, effect according to overhead cam reduces angular velocity of rotation, play the effect that slows down big closing speed, and use the smaller cam of size, to utilize a lot of spaces in the lower end.

The specific embodiment

Below by with reference to the accompanying drawings, embodiment of the present utility model is described.

Fig. 4 illustrates hinge camshaft of the present utility model from multi-angle.On the hinge 40 in conjunction with two cams.The size of overhead cam 42 is big, and the size of following cam 44 is less than overhead cam 42.Overhead cam 42 and following cam 44 are combined on the hinge 40 across certain intervals at the direction of principal axis of hinge cam axle.

Fig. 5 a and Fig. 5 b illustrate the hinge assembly of the utility model embodiment.

Hinge cam axle as shown in Figure 4 is combined on lower plate and the upper plate, and lower plate and upper plate are combined in the support sector again separately.As well-known in the industry, the function of compression spring plays in support sector.The following cam 504 that is combined on the hinge 500 is placed on the square shape lower plate 506.Because the size of following cam 504 greater than the peristome that is formed on the square shape lower plate 506, does not come off below square shape lower plate 506 so worry cam.Contraband font upper plate 508 is sandwiched between overhead cam 502 and the following cam 504, and square shape lower plate and Contraband font upper plate are combined in the support sector by bolt 510,512 as shown in the figure separately.Along with the hinge rotation, by action of cam, implement rectilinear motion except the remainder of hinge cam axle, this is the same with well-known principle in the industry, so detailed.Roller is bonded on lower plate and the upper plate for this reason.As shown in the figure, in conjunction with first roller, 520, the second rollers 522 and the 3rd roller 524.As shown in Figure 6, form in order to press from both sides into first jack 530 and second jack 534 of first roller 520 and second roller 522, form in order to clamp the 3rd jack 534 that roller inserts rod at opposite side in a side of square shape lower plate.Be positioned at and form the 4th jack 540 and the 5th jack 542 on first jack 530 of square shape lower plate and second jack, the 534 corresponding locational Contraband font upper plates.One end of first roller 520 is sandwiched in 530 li of first jacks, is sandwiched in 532 li of second jacks and an other end is sandwiched in an end of the 4th jack 540, the second rollers 522, and an other end is inserted in 542 li of the 5th jacks.The two ends of first roller and second roller are thinner than central part for this reason.The end that roller inserts rod 526 is clipped in 534 li of the 3rd jacks, and other end breakthrough form is formed in the jack 538 on the 3rd roller plate and protrudes, and clamps the 3rd roller 524.

In Fig. 7, illustrate the floor map and the front schematic view of hinge assembly of the present utility model.Because following cam size is little, radius of gyration is also little, has therefore improved the availability in space, has reduced the floor spring overall dimensions.Hinge assembly of the present utility model in addition can be finished by simple assembling parts separately, so easy to manufacture and can save manufacturing cost.

The above only is a preferred implementation of the present utility model; should be understood that; for those skilled in the art; under the prerequisite that does not break away from the utility model principle; can also carry out some improvement and modification to the utility model, these improvement and modification also fall in the protection domain of the utility model claim.
