Description

Modularization furniture seat connecting shaft

Technical Field

The utility model belongs to the connecting axle field, concretely relates to modularization furniture seat connecting axle.

Background

The shaft is a cylindrical object which is penetrated in the middle of a bearing or a wheel or a gear, but is also a small part of a square, and the shaft is a mechanical part which supports a rotating part and rotates together with the rotating part to transmit motion, torque or bending moment. Generally, the connecting shaft is in a metal round rod shape, each section can have different diameters, parts which do rotary motion in the machine are arranged on the shaft, but the existing connecting shaft is mostly a fixed-length connecting shaft, when the required length is changed, the connecting shafts of different models can only be replaced, and the function is single.

SUMMERY OF THE UTILITY MODEL

In order to solve the technical problem, the utility model provides a can change length after the combination as required, manifold modularization furniture seat connecting axle of function.

For realizing above-mentioned purpose, the utility model discloses a technical scheme be, a modularization furniture seat connecting axle, its structural feature is, be equipped with the center pin of screw hole including outer tube, interior sleeve pipe, center cover, backup pad and terminal surface, the outer tube pass the backup pad and with backup pad welded connection, interior sleeve pipe is inserted and is established in the outer tube, single festival axle is constituteed to outer tube, interior sleeve pipe and backup pad, single festival axle is the several, the center pin insert establish in the inner tube of several single festival axle to connect component a connecting axle with several single festival axle, the center cover establish the tip at the outer tube, the backup pad on be equipped with the through-hole of several array, the end of center pin can dismantle and be connected with the head.

As a further improvement of the utility model, the center sleeve is made of polypropylene.

As a further improvement of the utility model, the center sleeve and the outer sleeve are connected by a flat head self-tapping screw.

As a further improvement, the seal head comprises a connecting rod and a seal plate, and the connecting rod and the seal plate are integrally formed.

As a further improvement, the surface of the connecting rod is provided with threads, and the connecting rod is screwed in the threaded hole.

The utility model has the advantages that: reasonable in design, simple structure can change the combination according to the actual need environment of self to the connecting axle to change length in order to satisfy the demand, just so reduced use cost, can also play spacing and supported effect through the backup pad.

Drawings

Fig. 1 is a schematic sectional structure of the present invention;

the device comprises a base, a support plate, a central shaft, a connecting rod, a sealing plate, a support plate, a central shaft, a central sleeve, a support plate, a central shaft, a threaded hole, a through hole, an end socket, a connecting rod and a sealing plate, wherein the base comprises 1-an outer sleeve, 2-an inner sleeve, 3-a central sleeve, 4-the support plate, 5-the central.

Detailed Description

The invention is further explained with reference to the drawings, without limiting the scope of protection of the invention.

As shown in fig. 1, a modular furniture seat connecting shaft comprises an outer sleeve 1, an inner sleeve 2, a central sleeve 3, a supporting plate 4 and a central shaft 5, wherein the end face of the central shaft 5 is provided with a threaded hole 6, the outer sleeve 1 penetrates through the supporting plate 4 and is welded with the supporting plate 4, the inner sleeve 2 is inserted in the outer sleeve 1, the inner sleeve 2 and the supporting plate 4 form a plurality of single-joint shafts, the central shaft 5 is inserted in the inner sleeves 2 of the plurality of single-joint shafts and connects the plurality of single-joint shafts to form a connecting shaft, the central sleeve 3 is arranged at the end part of the outer sleeve 1, the supporting plate 4 is provided with a plurality of arrays of through holes 7, and the tail end of the central; the central sleeve 3 is made of polypropylene; the central sleeve 3 is connected with the outer sleeve 1 by a flat head self-tapping nail; the end socket 8 comprises a connecting rod 9 and a sealing plate 10, and the connecting rod 9 and the sealing plate 10 are integrally formed; the surface of the connecting rod 9 is provided with threads, and the connecting rod 9 is screwed in the threaded hole 6.

When the connecting shaft is used, when a long connecting shaft is needed, the length of the connecting shaft can be adjusted by increasing the number of single-joint shafts and the number of the central shafts 5 and then connecting the single-joint shafts and the central shafts by using a long screw rod, and a limiting effect can be formed by the supporting plate 4.

It is obvious to a person skilled in the art that the invention is not restricted to details of the above-described exemplary embodiments, but that it can be implemented in other specific forms without departing from the spirit or essential characteristics of the invention. The present embodiments are therefore to be considered in all respects as illustrative and not restrictive, the scope of the invention being indicated by the appended claims rather than by the foregoing description, and all changes which come within the meaning and range of equivalency of the claims are therefore intended to be embraced therein, and any reference signs in the claims are not intended to be construed as limiting the claim concerned.
