Description

A kind of wind resistance knife flag

Technical field

The present invention relates to a kind of wind resistance knife flag.

Background technology

Knife flag is the show apparature of outdoor exhibition, no matter has wind not have the wind can to stretch, and is easy to viewing.But present knife flag But following technical problem is faced：

If the 1, outdoor display scene wind-force is too big, the askew of knife flag can be caused, be made troubles to exhibition；

2nd, knife flag side is provided with the collar or bagging, but when display scene is arranged, due to the collar or set The general bore that sets of bag is only more slightly larger than loop bar, thus the collar or bagging is more time-consuming through the process on loop bar, sternly Operating efficiency is have impact on again；

3rd, when display scene is, it is necessary to knife flag loop bar is inserted when cement or marble etc. compare the ground of rigid planar On base, base is hollow plastic device, is poured water inside when using to support knife flag loop bar, and two are typically provided on base Hole, the water inlet positioned at the discharge outlet of base bottom and above base, but easily there is gas in cavity when pouring water Not out, current do not go down phenomenon body row, and this also result in wasting time and energy in work, have a strong impact on operating efficiency；

4th, the collar or bagging above knife flag easily cause knife to design opening when display scene wind-force is larger The curling of flag is so that knife flag is wrapped on whole loop bar the meaning for losing displaying.

The content of the invention

In order to solve the above-mentioned technical problem, be arranged to knife flag when there is high wind by the present invention, and knife flag can be rotated with box haul, It is askew so as to avoid, with being fixed easily, advantage easy to install.

To achieve these goals, the technical solution adopted by the present invention is as follows：

A kind of wind resistance knife flag, including bar of helping pull a cart is stretched, the bar of helping pull a cart of stretching is made up of interior loop bar with outer loop bar, the outer loop bar It is socketed in outside the interior loop bar, the outer loop bar bottom is provided with fastening kit, and the outer loop bar top is provided with clutch shaft bearing, described On outer loop bar outer wall, the bearing inner race is fixedly connected bearing holder (housing, cover) with the outer loop bar, and the bearing outer ring is fixedly connected First cross bar, is fixedly connected the first fixed mount on the outer loop bar outer wall, first fixed mount passes through with first cross bar Torsion spring hinge is hinged.Being connected by bearing can be such that knife flag freely rotates, askew so as to avoid, while increased torsion spring be hinged, When the abatement of wind or elimination, knife flag replys original arrangement, increases aesthetics, and what convenience showed is normally carried out playing publicity Effect.Employing expansion link instead of original straight-bar simultaneously, knife flag frame is easy to carry, save space.

Can be dismantled between first cross bar and clutch shaft bearing outer ring.By between the first cross bar and clutch shaft bearing Connection is designed as dismountable connection, is convenient for carrying, save space.

The bearing outer ring is fixedly connected fixed plate, and the fixed plate is parallel with outer loop bar, is uniformly set in the fixed plate There are several buckles.Directly knife flag side can thus be secured, eliminate and be originally inserted in the knife flag collar or bagging The complicated processes of loop bar.

The outer loop bar bottom is provided with second bearing, and the second bearing is sleeved on outer loop bar outer wall, the second bearing Inner ring is fixedly connected with the outer loop bar, and the second bearing outer ring is fixedly connected the second cross bar, solid on the outer loop bar outer wall Surely the second fixed mount is connected, second fixed mount is hinged with second cross bar by torsion spring hinge.The second cross bar is increased, Knife flag can preferably be launched, while when having wind, knife flag is not susceptible to curling and causes winding.

The wind resistance knife flag also includes base, and the base and interior loop bar are the connection that can be dismantled.When display scene is During the more hard floor such as concrete floor or marble, knife flag can still be used.

The base is provided with an osculum, a water inlet and a steam vent；The osculum is located at base bottom Portion；The water inlet is located at base top with discharge outlet.Increase an exhaust outlet it is possible to prevente effectively from because the blocking of air is made The phenomenon do not entered is filled into water, operating efficiency is improve.

First cross bar or the second cross bar are provided with the buckle I that can be dismantled.Increasing buckle I can preferably fix Knife flag, winds caused by further preventing knife flag from curling occurring because of wind-force.

The buckle I is provided with through hole, and the buckle I is fixed by bolts to the first cross bar or the second cross bar by through hole On.Fixed using bolt, it is easy for installation, and can be without installing when the buckle is not needed.

Beneficial effects of the present invention install quick for easy to use, the advantages of wind resistance.

Specific embodiment

In order to be better understood by technical scheme, the invention will be further described below in conjunction with the accompanying drawings.

As shown in Figures 1 and 3, a kind of wind resistance knife flag, including bar of helping pull a cart is stretched, the bar of helping pull a cart of stretching is by interior loop bar 2 and overcoat Bar 1 is constituted, and outer loop bar 1 is socketed in outside interior loop bar 2, and the bottom of outer loop bar 1 is provided with fastening kit 3, and the top of outer loop bar 1 is provided with first axle 4 are held, clutch shaft bearing 4 is sleeved on the outer wall of outer loop bar 1, the inner ring of clutch shaft bearing 4 is fixedly connected with outer loop bar 1, clutch shaft bearing outer ring The first cross bar 6 is fixedly connected, the first fixed mount 5 is fixedly connected on outer loop bar outer wall, the first fixed mount 5 passes through with the first cross bar 6 Torsion spring hinge 17 is hinged.

As shown in figs. 4 and 5, the first cross bar includes crossbar joint 18 and the cross bar body of rod 19, between crossbar joint and the body of rod Can dismantle, be i.e. can be dismantled between the first cross bar and clutch shaft bearing outer ring, torsion spring hinge be located at crossbar joint with Between first fixed mount, the effect of being hinged is played, so design is convenient for carrying, knife flag is returned to original exhibition position during the abatement of wind Put.
