Abstract

The embodiment provided by the invention discloses an adjustable bidirectional bearing. The bearing comprises a large axle bumper, a small axle bumper, a main hub disk, a steering column jacket and a fixed screw. The bearing can mitigate the bearing gap problem in machinery and furniture products, and has advantages of thin volume, strong bearing capability, simple installation, wide scope of adaptation, so as to provide a novel variety for the bearing industry.

Description

Adjustable double is to bearing

Technical field

The present invention relates to Furniture fittings, the technical fields such as mechanical five metals, be specifically related to a kind of novel bearing.

Background technique

Along with mechanical intellectuality, the multi-purpose of furniture, also more and more higher to the Functional Requirement of five metals, the present invention designs the multiduty bearing of a multi-steering, improves the needs of the polytrope of machinery and furniture.

Summary of the invention

Large in order to solve taking up room of existing bearing, gap can not regulate and control, the shortcomings such as loaded down with trivial details are installed, invent a kind of adjustable double to bearing, it can be used as the double steering structure of various machinery or furniture and uses, and the thin connection of volume of the present invention is simple, strong adaptability, validity is high, goes slick, and can put forward the applicability of movable part.

Described adjustable double is connected with workpiece by large axle bumper to bearing, and large axle bumper and the little axle bumper clamping spindle dish that is threaded, because its worm structure can effectively be adjusted at steel ball between axle bumper and main shaft disk and the gap of overcoat.Improve its validity.The present invention is double-deck steel ball structure, and the upper strata steel ball is different apart from the axle center size with the lower floor steel ball, thereby greatly improves its bearing capacity than existing bearing structure, improves again its impact resistance.

The accompanying drawing explanation

In order to be illustrated more clearly in the embodiment of the present invention or technological scheme of the prior art, below will the accompanying drawing of required use in embodiment or description of the Prior Art be briefly described, accompanying drawing in the following describes is only embodiments of the invention, to those of ordinary skills, under the prerequisite of not paying creative work, can also obtain according to these accompanying drawings other accompanying drawing.

Fig. 1 is that the bearing in the embodiment of the present invention is looked up design sketch;

Fig. 2 is the bearing side-looking design sketch in the embodiment of the present invention;

Fig. 3 is that the bearing parts in the embodiment of the present invention decomposes design sketch;

Below in conjunction with the accompanying drawing in the embodiment of the present invention; technological scheme in the embodiment of the present invention is clearly and completely described; obviously; described embodiment is only the present invention's part embodiment; embodiment based in the present invention; those of ordinary skills are not making under the creative work prerequisite, and the every other embodiment who obtains, belong to the scope of protection of the invention.

The embodiment of the invention discloses novel adjustable double to bearing, further describe below in conjunction with accompanying drawing.

Accompanying drawing 1 and accompanying drawing 2 are overall structure design sketchs, in accompanying drawing, turn to axle sleeve 7 and steering column jacket 8 to use separately, also can.

In accompanying drawing 3, around large axle bumper 1, there is the structure hole 6 that connects workpiece to be connected with other moveable workpiece, and middle have tapped hole to be connected with the hollow thread bar of little axle bumper 3, when in accompanying drawing 3, large axle bumper is threaded with little axle bumper, clamping spindle dish 2 and upper and lower steel ball 4 and 5.Form seamless connectivity, steering column jacket 7 and steering column jacket 8 can be fixed on below main shaft disk by standing screw 10, and the steering shaft that also can be used alone 7 or steering shaft 8, because in the middle of its bearing, having circular hole can pass through cable, avoided the numerous and diverse problem of wiring.

The present invention has applied specific case herein principle of the present invention and mode of execution has been set forth, and above embodiment's explanation is just for helping to understand the present invention and core concept thereof; Simultaneously, for one of ordinary skill in the art, according to inventive concept, the part that all changes in specific embodiments and applications, this description section is interpreted as the limitation of the present invention file.

Claims

1. a multipurpose adjustable double, to bearing, comprises large axle bumper, main shaft disk, little axle bumper, steel ball, steering column jacket, steering column jacket screw.

2. adjustable double is that tapped hole by large axle bumper is connected with the hollow thread bar of little axle bumper to bearing as claimed in claim 1, comes the clamping spindle dish to form the gapless contact, increases validity and stability.

3. adjustable double has the fixation workpiece hole around the large axle bumper of bearing as claimed in claim 1, can with other workpiece combination, main shaft disk has the screw hole is connected with steering column jacket to be connected with steering column jacket, has facilitated the operability of bearing installation, facilitates installation.

4. adjustable double can be used separately wherein one or two to the steering column jacket of bearing as claimed in claim 3, facilitates the needs of different parts.

5. also steering column jacket can be installed as claimed in claim 4, directly utilize the fixedly steering shaft screw hole of main shaft disk to be connected with other workpiece, increase versatility.

6. so as claimed in claim 2 little axle bumper is hollowly can pass through the electrical equipment cable, has avoided mixed and disorderly connecting line.
