Abstract

The invention discloses a fixing device of columns, which comprises a buckle strap (1) and a buckle piece (2) for binding, a fastening card (3) is sleeved on the buckle strap, and a hole (8) is arranged on the fastening card. In binding state, after the buckle strap (1) is wound on the column, two ends of the buckle strap (1) penetrate through the hole (8) on the fastening card, then are wound on an attachment, and are tightly fixed by the buckle piece (2). The steps of the device of the invention which fixes columns on other attachments include firstly winding one end of the buckle strap on a column, leading the buckle strap to sequentially penetrate two ends of a groove of the hole of the fastening card, and then tightly pulling the two ends of the buckle strap to fasten the column. The fixing device for columns is characterized in that the buckle strap and the fastening card have anti-rust and anti-corrosion property, the buckle strap has certain flexibility, and can be bent, and a protective column on the fastening card can protect the buckle strap, the fixing device brings convenience for fixing the column, and increases the applicability of the device.

Description

A kind of fixing device of column

Technical field

The present invention relates to a kind of column is fixed on device on other attachment, relate in particular to a kind of fixing device of column.

Background technique

At present column is fixed on the attachment, normally cingulum is twined column and attachment, cause and fix and dismantle loaded down with trivial details difficulty.And in the process of twining, inevitably cingulum and binding are caused certain damage, through exposing to the weather, the corrosion that gets rusty easily has reduced working life, has increased maintenance cost.Secondly, just means of transportation such as street lamp, signaling lamp, traffic mark board are wrapped on the same roofbolt brokenly, because artificial or nature, fixed mass is low, and column tilts easily.Just become refuse after " accessories " such as last cingulums disassembles, can not reuse.

Summary of the invention

The invention provides and a kind ofly can improve the device of being tied up the column fixed mass.

The present invention adopts following technological scheme: a kind of fixing device of column comprises cingulum and the fastener that is used to bind, sheathed fastening card on cingulum.Fastening card is made up of the first cylinder rod member, the second cylinder rod member, head rod and second connecting rod, the two ends of head rod are connected with an end of the first cylinder rod member, the second cylinder rod member respectively, the two ends of second connecting rod are connected with the other end of the first cylinder rod member, the second cylinder rod member respectively, and, be located at hole on the fastening card and surround by the first cylinder rod member, the second cylinder rod member, head rod and second connecting rod and form.At binding state, cingulum is behind column, and the hole of fastening card is passed at the two ends of cingulum, tightens up on attachment and by fastener again.

Compared with prior art, the present invention has following advantage:

1, the gap affects of column and cingulum the fixing quality of column, the use of fastening card has effectively reduced the gap of cingulum and column and cingulum and attachment, make between cingulum and the column and better applying between cingulum and the attachment, increased the area of contact of cingulum and column, reduce the pressure on the unit area, improved the fixed mass of column.

2, the use of cylinder rod member has relaxed the wide-angle distortion of cingulum, and the frictional force that has reduced to stretch in fixation procedure is convenient fixing.Simultaneously, the use of cylinder rod member has increased the area of contact of cingulum and fastening card, has prolonged the working life of cingulum.

3, fastening card device uses the antirust, anti-corrosive corrosion material to make, and can improve working life.

4, the present invention adopts the mode that " module " set up, and has improved the versatility of fastening card, saves resource, the protection environment.

5, the fixing device simple structure is easy and simple to handle, and is economical and practical.

6, fixing device provided by the invention realizes the fixing of a plurality of columns on the adjunct more easily.

7, cingulum can be crooked to a certain extent, is easy to realize fixing the different column of thickness.

Embodiment

A kind of fixing device of column comprises cingulum 1 and the fastener 2 that is used to bind, sheathed fastening card 3 on cingulum 1, on fastening card, be provided with hole 8, at binding state, cingulum 1 on the column after, the hole 8 on the fastening card is passed at the two ends of cingulum 1, is tightening up on attachment and by fastener 2.

Fastening card 3 is made up of the first cylinder rod member 4, the second cylinder rod member 5, head rod 6 and second connecting rod 7, the two ends of head rod 6 are connected with an end of the first cylinder rod member 4, the second cylinder rod member 5 respectively, the two ends of second connecting rod 7 are connected with the other end of the first cylinder rod member 4, the second cylinder rod member 5 respectively, and, be located at hole 8 on the fastening card and surround by the first cylinder rod member 4, the second cylinder rod member 5, head rod 6 and second connecting rod 7 and form.

With reference to accompanying drawing the present invention is made more detailed explanation:

With reference to Fig. 1, Fig. 1 is the cingulum schematic representation.Cingulum has certain width, can increase the area of contact of cingulum and fixture and cingulum and attachment, reduces the pressure on the unit area, improves fixed mass.Cingulum has certain flexibility, has made things convenient for cingulum to pass fastening card.Cingulum constitutes with rust preventive material, improves working life.

With reference to Fig. 2, Fig. 2 is the fastener schematic representation, and the use by fastener realizes the fixing of cingulum.The concrete detailed rules and regulations of the use of fastener can an eastern patent is a kind of to be fixed on banded fastener and method thereof on the cylindrical rod with object referring to being permitted.

With reference to Fig. 3,4, Fig. 3 is fastening card pictorial diagram, Fig. 4 is fastening card three-view diagram.Fastening card is made up of the first cylinder rod member 4, the second cylinder rod member 5, head rod 6 and second connecting rod 7 fastening card in Fig. 3, and on the fastening card rectangular opening 8 is arranged.Fig. 4 a, 4b, 4c are respectively the plan view of fastening card, side view and plan view.

With reference to Fig. 5,6, Fig. 5, the 6th, the supporting operation instruction figure of fastening zipper tape during no fixture.In fixation procedure, earlier an end of cingulum is passed (Fig. 5) along the cylinder rod member of fastening card, then cingulum is passed another cylinder rod member (Fig. 6) of fastening card.

With reference to Fig. 7,8, Fig. 7,8 are to use the fixing device plan view of rectangular-shaped fastening card and the fastening card of use column.Be not difficult to find that in rectangular-shaped fastening card using process, tie is at four points (among Fig. 79 by Fig. 9,10 contrast, 10 and symmetric points, be four lines in the pictorial diagram) the wide-angle distortion takes place, and also the stress surface of the outside tension force of column is wire in this zone, damages tie easily.And in Fig. 8, it is planar that the force bearing point of the outside tension force of the fastening card column of column is rendered as, and its area of contact is big.

With reference to Fig. 9,10.Fig. 9, the 10th, fastening card operation instruction figure in the fixing device.In fixation procedure, earlier an end of the cingulum cylinder rod member along fastening card is passed, the column that hovers then passes cingulum another cylinder rod member (Fig. 9) of fastening card, at the two ends (Figure 10) of tension cingulum.

With reference to Figure 11.Figure 11 is two fixing device fixed length column schematic representation.In Figure 11, for the fixed mass that improves the long column shape thing has used two fixing devices.
