Abstract

The utility model relates to a supporting rod, which comprises an outer tube, an inner tube and a supporting disk which are sheathed and overlapped with each other, wherein one end of the outer tube is fixedly provided with an inner stopper of the stopping and butting inner tube; the outer tube is provided with a hole which is matched and combined with a positioning pin, and a spring which can support the inner tube is arranged in the outer tube; the inner tube is provided with a long sliding slot which can be used for the positioning pin to penetrate; the inner tube which is supported by the spring is arranged on the outer tube by the positioning pin. Compared with the conventionally known art, the structure of the utility model is simpler and more direct. The utility model is provided with the spring which is arranged in the outer tube, and the spring supports the inner tube so that the length of the supporting rod can be automatically adjusted; the hinged structure of the supporting disk and connecting members enables the supporting rod to automatically be aligned. The utility model causes a product to be more convenient, more practical and more affinitive to accepters.

Description

Support bar

Technical field

The utility model belongs to the construction equipment field, relates to a kind of retractable supports bar of adjusting length and levelling structure that has, and is particularly suited for the supporting tool of interior decoration.

Background technology

The support bar of commonly using, the locking of its telescopic tube elements or bar, transfer long measure a lot, comparatively progressive as 022,436,715 1 kinds of step-by-step movement support bars of Chinese patent, comprise: telescopic outer tube element, inner tubular element and a pair of supporting disk, one end of wherein said outer tube element installs bar adjusting device in, install one and adjust interior bar, contain abdomen in telescopic, in the outer tube element, the other end of outer tube element installs a pin-and-hole formula positioning and locking device, pipe is provided with guide groove in described, along the equidistant lock hole that is provided with of this guide groove direction, the outer end of pipe installs the end pivot dress supporting disk of this joint of supporting disk joint in flexible, and the outer end pivot of flexible interior bar is adorned another supporting disk, and this can pivot supporting disk.

Known support bar normally disposes locking and transfers long device, and the support bar that the market demand structure is more simple and direct makes manufacturing cost lower, but preferably has the support bar people more just who adjusts length and levelling structure voluntarily.

Summary of the invention

Problem to be solved in the utility model be to answer market urgently, overcome the deficiencies in the prior art, a kind of support bar of adjusting length and levelling structure voluntarily that has is provided.

The utility model solves its technical problem and takes following technical scheme to realize:

A kind of support bar that provides according to the utility model, comprise: outer tube, interior pipe and the supporting disk of mutual intussusception, wherein, an end of described outer tube installs one and only supports the interior stifled of interior pipe, the hole that combines with the alignment pin coupling is set on the outer tube, and one can hold the spring assembly of interior pipe in outer tube; Be provided with one on the pipe in described and can be total to the microscler chute that alignment pin passes; Interior pipe is held by dowel device on outer tube by spring.

It is to take following technical scheme further to realize that the utility model solves its technical problem:

Aforesaid support bar, wherein, described interior pipe connects by linkage element with supporting disk, the attachment that this linkage element one end setting combines with inner pipe joint end coupling, the other end is convexly equipped with the linkage element articulated section of an assembling supporting disk; Described supporting disk has the supporting disk articulated section that combines with linkage element articulated section coupling and connects by prohibiting firmware by hinge dress hole;

Aforesaid support bar wherein, is provided with the support backing plate and installs by the pin-and-hole on the supporting disk by the pin that supports on the backing plate on the described supporting disk;

Aforesaid support bar, wherein, the pin on the described support backing plate is provided with the horse-hof shape bottom, and the pin-and-hole on the described supporting disk is set to meet macropore that supports backing plate pin horse-hof shape bottom and the aperture that meets the pin neck that is communicated with this macropore.

The utility model compared with prior art has significant advantage and beneficial effect.

By above technical scheme as can be known, under its excellent structure configuration, have following advantage at least:

This case and known technology structure compared are more simple and direct rationally, load better effects if, this case are provided with the spring that the interior device of outer tube holds interior pipe, make support bar can adjust length voluntarily, the hinge assembling structure of supporting disk and connecting piece can be gone levelling by support bar, and the utility model makes the more convenient practicality of product.More affine audient.

For further understanding technology contents of the present utility model, characteristics and effect, exemplify following preferred embodiment now, and conjunction with figs. is described in detail as follows:

The specific embodiment of the present utility model is provided in detail by following most preferred embodiment.

Description of drawings

Fig. 1 is an overall structure schematic diagram of the present utility model;

Fig. 2 is the A-A line of vision structural representation of supporting disk in the utility model.

The specific embodiment

Below in conjunction with accompanying drawing and preferred embodiment, the specific embodiment, structure, feature and effect thereof that foundation the utility model is provided, describe in detail as after.

See also Fig. 1-2, a kind of support bar comprises: outer tube 1, interior pipe 2 and the supporting disk 5 of mutual intussusception, wherein, one end of described outer tube installs one and only blocks up 11 to the interior of interior pipe, and the spring 3 that the hole 12, that setting combines with alignment pin 4 couplings on the outer tube can hold interior pipe installs in outer tube; Be provided with one on the pipe in described and can be total to the microscler chute 22 that alignment pin passes; Interior pipe is held by dowel device on outer tube by spring 3, and interior pipe is subjected to the force compresses spring, and interior pipe tightens outer tube, and pipe stretched out in the pipe spring held in discharging, thereby the realization body of rod is adjusted the technique effect of length automatically.

One linkage element 6 combines with supporting disk, the attachment 61 that linkage element one end setting combines with inner pipe joint end 21 couplings, the other end is convexly equipped with the linkage element articulated section 62 of an assembling supporting disk 5, the configuration of linkage element makes the part of the force load of support bar more reasonable, the oral area that is coupled part also there is the protection effect, the load better effects if; Described supporting disk 5 has the supporting disk articulated section that combines with linkage element articulated section coupling and connects by prohibiting firmware by hinge dress hole; Supporting disk and the linkage element hinge dress that combines interior bar make support bar can realize the purpose of levelling voluntarily.

Support backing plate 7 is set on the described supporting disk to be installed by the pin-and-hole on the supporting disk 51 by the pin 71 that supports on the backing plate; Pin 71 on the described support backing plate is provided with horse-hof shape bottom 711, pin-and-hole on the described supporting disk is set to meet macropore that supports backing plate pin horse-hof shape bottom and the aperture that meets the pin neck that is communicated with this macropore, this pin-and-hole is the figure of eight, and the operator can install and be locked on the gripper shoe supporting backing plate very easily.

After the preferred embodiment that describes in detail, being familiar with this technology personage can clearly understand, do not breaking away under described claim and the spirit, can carry out various variations and modification, and the utility model also is not subject to the embodiment of illustrated embodiment in the manual.
